Item 1.01.     Entry into a Material Definitive Agreement

     (a) New Term Loans.

     We, together with Brandywine Operating Partnership, L.P., the subsidiary through which we own our assets and conduct our business, and certain subsidiaries of our operating partnership, entered into two term loan credit agreements, effective as of September 21, 2004. One credit agreement (“Credit Agreement I”) provides for a loan (“Loan I”) in a principal amount of up to $320 million and the other credit agreement (“Credit Agreement II”) provides for a loan (“Loan II”) in a principal amount of up to $113 million. We used the proceeds of Loan I and Loan II, together with a portion of the proceeds from our recent sale of 7,750,000 common shares, to fund a portion of the consideration payable in our acquisition of The Rubenstein Company, L.P. (including to repay a portion of the mortgage debt assumed as part of the transaction), and to pay related fees and expenses. Each of Credit Agreement I and Credit Agreement II, like the Revolving Credit Facility, is recourse to us and to those of our subsidiaries that are parties, as guarantors, to Credit Agreement I and Credit Agreement II (which are the same subsidiaries that are guarantors of the Revolving Credit Facility).

     Loan I matures on May 24, 2007 and Loan II matures on September 20, 2008. There is no scheduled principal amortization of either Loan I or Loan II. Loan I is subject to mandatory prepayment in an amount equal to proceeds of equity that we may hereafter issue and is also subject to mandatory prepayment in an amount equal to net proceeds of debt that we sell in a publicly registered transaction. Loan I is also subject to mandatory prepayment in an amount equal to net proceeds of debt that we sell in any privately placed, non-Rule 144A or 144A (with no registration rights) offering to the extent the net proceeds exceed $115 million. Loan II is subject to mandatory prepayment in an amount equal to the first $115 million of net proceeds of debt that we sell in any privately placed, non-Rule 144A or 144A (with no registration rights) offering.

     Loan I bears interest at a per annum floating rate equal to: (i) the higher of (x) the prime rate announced publicly by JP Morgan Chase Bank or (y) the federal funds rate plus .50% per annum, plus, in either case, between .05% and .70%, depending on our debt rating, whether Loan I is outstanding more than 90 days and our leverage ratio or (ii) a Eurodollar rate that is the rate at which Eurodollar deposits for similar interest periods are offered plus between 1.05% and 1.70%, depending on our debt rating, whether Loan I is outstanding for more than 90 days and our leverage ratio. Loan II bears interest at a per annum floating rate equal to: (i) the higher of (x) the prime rate announced publicly by JP Morgan Chase Bank or (y) the federal funds rate plus .50% per annum, plus, in either case, between .30% and .95%, depending on our debt rating, whether Loan II is outstanding for more than 90 days and our leverage ratio or (ii) a Eurodollar rate that is the rate at which Eurodollar deposits for similar interest periods are offered plus between 1.30% and 1.95%, depending on our debt rating, whether Loan II is outstanding for more than 90 days and our leverage ratio.

     The agreements providing for Loan I and Loan II contain financial and operating covenants similar to those in the agreement providing for the Revolving Credit Facility. Financial covenants include minimum interest coverage, fixed charge, minimum net worth ratios and other financial tests. Operating covenants include limitations on our ability to incur additional indebtedness, grant

                  THIRTEENTH AMENDMENT TO AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                     BRANDYWINE OPERATING PARTNERSHIP, L.P.

                  THIS THIRTEENTH AMENDMENT, dated as of September 21, 2004 (the
"Amendment"), further amends the Amended and Restated Agreement of Limited
Partnership Agreement (as amended to date, the "Partnership Agreement") of
BRANDYWINE OPERATING PARTNERSHIP, L.P., a Delaware limited partnership (the
"Partnership"). Capitalized terms used herein but not defined herein shall have
the meanings given such terms in the Partnership Agreement.

                                   BACKGROUND

         A. Pursuant to the Partnership Agreement, Brandywine Realty Trust (the
"General Partner"), as the general partner of the Partnership, has the power and
authority to issue additional Partnership Interests to persons on such terms and
conditions as the General Partner may deem appropriate.

         B. The General Partner, pursuant to the exercise of such power and
authority and in accordance with the Partnership Agreement, has determined to
execute this Amendment to the Partnership Agreement to evidence the issuance of
additional Partnership Interests and the admission of the other signatories
hereto as Limited Partners of the Partnership in exchange for certain
contributions of interests in real estate and real estate related assets that
are being made to the Partnership on the date hereof pursuant to the
Contribution Agreement dated as of August 18, 2004 by and among the Partnership
and the other parties thereto.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt,
adequacy and sufficiency of which are hereby acknowledged, the parties hereto,
intending to be legally bound, hereby amend the Partnership Agreement as
follows:

         1. The Partnership Agreement is hereby amended to reflect the admission
as a Limited Partner on the date hereof of the Persons set forth on Schedule A
attached hereto (the "Admitted Partners") and the ownership by such Persons of
the number of Class A Units listed opposite each Person's name on Schedule A.
Attached as Schedule B is a list of the Partners of the Partnership prior to the
admission of the Admitted Partners, together with the number and class of
Partnership Interests owned by such partners.

         2. The Partnership Interests issued hereby shall constitute Class A
Units under the Partnership Agreement; provided that any distribution to be
received by the Admitted Partners on the Class A Units issued to them on the
date hereof on account of the fiscal quarter in which they are admitted to the
Partnership shall be pro-rated to reflect the portion of the fiscal quarter of
the Partnership for which the Admitted Partners held such Class A Units and
shall not be pro-rata in accordance with their then Percentage Interests;
provided further that the Redemption Right granted to holders of Class A Units
in Article XV of the Partnership Agreement shall not be exercisable by the
holders of the Class A Units issued on the date hereof to the Admitted Partners
until the first anniversary of the date hereof, except that (i) if the holder of
any such Class A Units dies, such holder's estate shall thereupon be permitted
to exercise the Redemption Right with respect to all of such Class A Units held
by it notwithstanding the foregoing restriction and (ii) if a Change of Control
(as defined below) of the General Partner occurs, the foregoing restriction on
exercise of the Redemption Right shall automatically terminate with respect to
all of such Class A Units.




         3. As used herein, the term "Change of Control" shall mean:

            (i)     the acquisition in one or more transactions by any "Person"
                    (as the term person is used for purposes of Sections 13(d)
                    or 14(d) of the Exchange Act) of "Beneficial ownership"
                    (within the meaning of Rule 13d-3 promulgated under the
                    Exchange Act) of twenty-five percent (25%) or more of the
                    combined voting power of the General Partner's then
                    outstanding voting securities (the "Voting Securities"),
                    provided that for purposes of this clause (i) Voting
                    Securities acquired directly from the General Partner by any
                    Person shall be excluded from the determination of such
                    Person's Beneficial ownership of Voting Securities (but such
                    Voting Securities shall be included in the calculation of
                    the total number of Voting Securities then outstanding); or

            (ii)    approval by shareholders of the General Partner of:

                    (A)  a merger, reorganization or consolidation involving the
                         General Partner if the shareholders of the General
                         Partner immediately before such merger, reorganization
                         or consolidation do not or will not own directly or
                         indirectly immediately following such merger,
                         reorganization or consolidation, more than fifty
                         percent (50%) of the combined voting power of the
                         outstanding voting securities of the General Partner
                         resulting from or surviving such merger, reorganization
                         or consolidation in substantially the same proportion
                         as their ownership of the Voting Securities outstanding
                         immediately before such merger, reorganization or
                         consolidation; or

                    (B)  a complete liquidation or dissolution of the General
                         Partner; or

                    (C)  an agreement for the sale or other disposition of all
                         or substantially all of the assets of the General
                         Partner; or




            (iii)   acceptance by shareholders of the General Partner of shares
                    in a share exchange if the shareholders of the General
                    Partner immediately before such share exchange do not or
                    will not own directly or indirectly immediately following
                    such share exchange more than fifty percent (50%) of the
                    combined voting power of the outstanding voting securities
                    of the entity resulting from or surviving such share
                    exchange in substantially the same proportion as their
                    ownership of the Voting Securities outstanding immediately
                    before such share exchange.

         4. By execution of this Amendment to the Partnership Agreement by the
General Partner, the Admitted Partners agree to be bound by each and every term
of the Partnership Agreement as amended from time to time in accordance with the
terms of the Partnership Agreement.

         5. On the date of this Amendment, each of the Admitted Partners shall
execute and deliver to Brandywine Realty Trust an Irrevocable Proxy coupled with
an Interest in the form set forth on Exhibit 1 hereto attached.

         6. Except as expressly set forth in this Amendment to the Partnership
Agreement, the Partnership Agreement is hereby ratified and confirmed in each
and every respect.







         IN WITNESS WHEREOF, this Amendment to the Partnership Agreement has
been executed and delivered as of the date first above written.

to a Credit Party or one of its Subsidiaries solely as a result of such Credit
Party (or Subsidiary) being a partner or member in such joint venture shall be
treated as not recourse to such Credit Party (or Subsidiary) as long as the only
assets owned by such Credit Party (or Subsidiary) are its equity interest in
such joint venture and any contributed capital held to fund such equity
interest.

                                   SECTION 2

                                 CREDIT FACILITY

2.1.     TERM LOANS.

         (a) Term Loans. Subject to the terms and conditions set forth herein,
each Lender severally agrees, on the Effective Date, to make a term loan
(collectively, the "Term Loans") to the Borrowers, in Dollars, in an amount
equal to such Lender's Term Loan Commitment Percentage of the aggregate amount
of Term Loans requested by the Borrowers to be made on such date; provided that
(i) the aggregate amount of Term Loans made may not exceed the Term Loan
Committed Amount and (ii) the Term Loans shall only be made in a single funding.
By no later than 11:00 a.m. on the Effective Date, and in no event later than
11:00 a.m. on October 21, 2004, the Borrowers shall submit an irrevocable
written Notice of Borrowing in the form of Exhibit 2.1(a) to the Administrative
Agent setting forth (A) the amount requested, (B) the specific use of the
proceeds of the requested Term Loans, (C) a certification that the Borrowers
have complied in all respects with Section 5.1 and (D) the date of borrowing.
The Administrative Agent shall provide copies of such Notice of Borrowing to
each Lender. The Commitments shall permanently terminate upon the making of the
Term Loans.

         (b) Funding of Term Loans. On the Effective Date, each Lender will make
its Term Loan Commitment Percentage of the aggregate amount of Term Loans
requested by the Borrowers available to the Administrative Agent by deposit, in
Dollars and in immediately available funds, at the Administrative Agent's office
at the Agency Services Address or at such other address as the Administrative
Agent may designate in writing. The amount of the Term Loans will then be made
available to the Borrowers by the Administrative Agent by crediting the account
of the Borrowers on the books of such office of the Administrative Agent, to the
extent the amount of such Term Loans are made available to the Administrative
Agent. All Term Loans made on the Effective Date shall be Base Rate Loans.
Thereafter, all or any portion of the Term Loans may be converted into
Eurodollar Loans in accordance with the terms of Section 2.1(d) and the
definition of "Interest Period" set forth in Section 1.1.

         No Lender shall be responsible for the failure or delay by any other
Lender in its obligation to make a Term Loan hereunder; provided, however, that
the failure of any Lender to fulfill its obligations hereunder shall not relieve
any other Lender of its obligations hereunder. Unless the Administrative Agent
shall have been notified by any Lender prior to the date of the Term Loans that
such Lender does not intend to make available to the Administrative Agent its
portion of the Term Loans to be made on such date, the Administrative Agent may
assume that such Lender has

                                      -23-


or will make the amount of its Term Loan available to the Administrative Agent
on the Effective Date, and the Administrative Agent in reliance upon such
assumption, may (in its sole discretion but without any obligation to do so)
make available to the Borrowers a corresponding amount. If such corresponding
amount is not in fact made available to the Administrative Agent, the
Administrative Agent shall be able to recover such corresponding amount from
such Lender. If such Lender does not pay such corresponding amount forthwith
upon the Administrative Agent's demand therefor, the Administrative Agent will
promptly notify the Borrowers, and the Borrowers shall immediately pay such
corresponding amount to the Administrative Agent. The Administrative Agent shall
also be entitled to recover from such Lender or the Borrowers, as the case may
be, interest on such corresponding amount in respect of each day from the date
such corresponding amount was made available by the Administrative Agent to the
Borrowers to the date such corresponding amount is recovered by the
Administrative Agent at a per annum rate equal to (i) from the Borrowers at the
Adjusted Base Rate and (ii) from such Lender at the Federal Funds Rate if paid
within two Business Days of the date of drawing and thereafter at a rate equal
to the Base Rate.

         (c) Term Notes. Upon the request of any Lender, the Borrowers shall
provide such Lender with a duly executed Term Note, evidencing the Term Loans
made by such Lender, in an original principal amount equal to such Lender's Term
Loan Commitment Percentage of the aggregate amount of the Term Loans requested
by the Borrowers to be made on such date and substantially in the form of
Exhibit 2.1(c).

         (d) Continuations and Conversions. The Borrowers shall have the option
with respect to all or any part of the Term Loans, on any Business Day, to
continue existing Eurodollar Loans for a subsequent Interest Period, to convert
Base Rate Loans into Eurodollar Loans, or to convert Eurodollar Loans into Base
Rate Loans; provided, however, that (i) each such continuation or conversion
must be requested by the Borrowers pursuant to a written Notice of
Continuation/Conversion, in the form of Exhibit 2.1(d), in compliance with the
terms set forth below, (ii) except as provided in Section 3.11, Eurodollar Loans
may only be continued or converted on the last day of the Interest Period
applicable thereto, (iii) Eurodollar Loans may not be continued nor may Base
Rate Loans be converted into Eurodollar Loans during the existence and
continuation of a Default or Event of Default and (iv) any request to continue a
Eurodollar Loan that fails to comply with the terms hereof or any failure to
request a continuation of a Eurodollar Loan at the end of an Interest Period
shall result in a conversion of such Eurodollar Loan to a Base Rate Loan on the
last day of the applicable Interest Period. Each continuation or conversion must
be requested by the Borrowers no later than 11:00 a.m. (A) one Business Day
prior to the date for a requested conversion of a Eurodollar Loan to a Base Rate
Loan or (B) three Business Days prior to the date for a requested continuation
of a Eurodollar Loan or conversion of a Base Rate Loan to a Eurodollar Loan, in
each case pursuant to a written Notice of Continuation/Conversion submitted to
the Administrative Agent (which shall promptly notify each of the Lenders) which
shall set forth (x) whether the Borrowers wish to continue or convert such Loans
and (y) if the request is to continue a Eurodollar Loan or convert a Loan to a
Eurodollar Loan, the Interest Period applicable thereto.

         (e) Minimum Amounts/Restrictions on Loans. Each request for a
conversion or continuation of a Term Loan shall be subject to the requirements
that (i) each Eurodollar Loan shall be in a minimum amount of $1,000,000 and in
integral multiples of $100,000 in excess

                                      -24-


thereof, (ii) each Base Rate Loan shall be in a minimum amount of $500,000 and
(iii) no more than four Eurodollar Loans shall be outstanding at any one time.
For the purposes of this Section 2.1(e), all Eurodollar Loans with the same
Interest Periods beginning on the same date shall be considered as one
Eurodollar Loan, but Eurodollar Loans with different Interest Periods, even if
they begin or end on the same date, shall be considered as separate Eurodollar
Loans.

2.2.     JOINT AND SEVERAL LIABILITY OF THE BORROWERS.

         (a) Each of the Borrowers is accepting joint and several liability
hereunder in consideration of the financial accommodation to be provided by the
Lenders under this Credit Agreement, for the mutual benefit, directly and
indirectly, of each of the Borrowers and in consideration of the undertakings of
each of the Borrowers to accept joint and several liability for the obligations
of each of them.

         (b) Each of the Borrowers jointly and severally hereby irrevocably and
unconditionally accepts, not merely as a surety but also as a co-debtor, joint
and several liability with the other Borrower with respect to the payment and
performance of all of the Obligations arising under this Credit Agreement and
the other Credit Documents, it being the intention of the parties hereto that
all the Obligations shall be the joint and several obligations of each of the
Borrowers without preferences or distinction among them.

         (c) If and to the extent that either of the Borrowers shall fail to
make any payment with respect to any of the Obligations as and when due or to
perform any of the Obligations in accordance with the terms thereof, then in
each such event, the other Borrower will make such payment with respect to, or
perform, such Obligation.

         (d) The obligations of each Borrower under the provisions of this
Section 2.2 constitute full recourse obligations of such Borrower, enforceable
against it to the full extent of its properties and assets.

         (e) Except as otherwise expressly provided herein, to the extent
permitted by law, each Borrower hereby waives notice of acceptance of its joint
and several liability, notice of occurrence of any Default or Event of Default
(except to the extent notice is expressly required to be given pursuant to the
terms of this Credit Agreement), or of any demand for any payment under this
Credit Agreement, notice of any action at any time taken or omitted by the
Administrative Agent or the Lenders under or in respect of any of the
obligations hereunder, any requirement of diligence and, generally, all demands,
notices and other formalities of every kind in connection with this Credit
Agreement. Each Borrower hereby assents to, and waives notice of, any extension
or postponement of the time for the payment of any of the Obligations, the
acceptance of any partial payment thereon, any waiver, consent or other action
or acquiescence by the Administrative Agent or the Lenders at any time or times
in respect of any default by either Borrower in the performance or satisfaction
of any term, covenant, condition or provision of this Credit Agreement, any and
all other indulgences whatsoever by the Administrative Agent or the Lenders in
respect of any of the obligations hereunder, and the taking, addition,
substitution or release, in whole or in part, at any time or times, of any
security for any of such obligations or the addition, substitution or release,
in whole or in part, of either Borrower. Without limiting the generality of the
foregoing, each Borrower assents to any other action or delay in acting or any
failure to act on the part of the

                                      -25-


Administrative Agent or the Lenders, including, without limitation, any failure
strictly or diligently to assert any right or to pursue any remedy or to comply
fully with applicable laws or regulations thereunder which might, but for the
provisions of this Section 2.2, afford grounds for terminating, discharging or
relieving such Borrower, in whole or in part, from any of its obligations under
this Section 2.2, it being the intention of each Borrower that, so long as any
of the Obligations hereunder remain unsatisfied, the obligations of such
Borrower under this Section 2.2 shall not be discharged except by performance
and then only to the extent of such performance. The obligations of each
Borrower under this Section 2.2 shall not be diminished or rendered
unenforceable by any winding up, reorganization, arrangement, liquidation,
reconstruction or similar proceeding with respect to either Borrower or a
Lender. The joint and several liability of the Borrowers hereunder shall
continue in full force and effect notwithstanding any absorption, merger,
amalgamation or any other change whatsoever in the name, membership,
constitution or place of formation of either Borrower or any of the Lenders.

         (f) The provisions of this Section 2.2 are made for the benefit of the
Lenders and their successors and assigns, and may be enforced by them from time
to time against either of the Borrowers as often as occasion therefor may arise
and without requirement on the part of the Lenders first to marshal any of its
claims or to exercise any of its rights against the other Borrower or to exhaust
any remedies available to it against the other Borrower or to resort to any
other source or means of obtaining payment of any of the Obligations hereunder
or to elect any other remedy. The provisions of this Section 2.2 shall remain in
effect until all the Obligations shall have been paid in full or otherwise fully
satisfied. If at any time, any payment, or any part thereof, made in respect of
any of the Obligations is rescinded or must otherwise be restored or returned by
the Lenders upon the insolvency, bankruptcy or reorganization of either of the
Borrowers, or otherwise, the provisions of this Section 2.2 will forthwith be
reinstated and in effect as though such payment had not been made.

         (g) Notwithstanding any provision to the contrary contained herein or
in any of the other Credit Documents, to the extent the obligations of either
Borrower shall be adjudicated to be invalid or unenforceable for any reason
(including, without limitation, because of any applicable state or federal law
relating to fraudulent conveyances or transfers) then the obligations of such
Borrower hereunder shall be limited to the maximum amount that is permissible
under applicable law (whether federal or state and including, without
limitation, the Bankruptcy Code).

2.3.     APPOINTMENT OF BOP.

         BRT hereby appoints BOP to act as its agent for all purposes under this
Credit Agreement (including, without limitation, with respect to all matters
related to the borrowing and repayment of Loans) and agrees that (i) BOP may
execute such documents on behalf of BRT as BOP deems appropriate in its sole
discretion and BRT shall be obligated by all of the terms of any such document
executed on its behalf, (ii) any notice or communication delivered by the
Administrative Agent or the Lender to BOP shall be deemed delivered to BRT and
(iii) the Administrative Agent or the Lenders may accept, and be permitted to
rely on, any document, instrument or agreement executed by BOP on behalf of BRT.

                                      -26-

         Notwithstanding anything herein to the contrary, no recourse shall be
had against Brandywine Realty Services Partnership or any past, present or
future shareholder, officer, director or trustee of BRT for any obligation of
the Credit Parties under the Credit Documents, or for any claim based thereon or
otherwise in respect thereof; provided, however, that this Section 2.4 shall not
restrict or limit any claim against any such Person arising out of or occurring
with respect to fraud or any intentional misrepresentation or any act or
omission that is willful or wanton or constitutes gross negligence or willful
misconduct.

                                   SECTION 3

Adjusted Base Rate. All Eurodollar Loans shall accrue interest at the Adjusted
Eurodollar Rate.

         (b) Default Rate of Interest. Upon the occurrence, and during the
continuance, of an Event of Default as set forth in Section 9.1(a), the
principal of and, to the extent permitted by law, interest on the Loans and any
other amounts owing hereunder or under the other Credit Documents (including
without limitation fees and expenses) shall bear interest, payable on demand, at
a per annum rate equal to four percent (4%) plus the rate which would otherwise
be applicable (or if no rate is applicable, then the rate for Base Rate Loans
plus four percent (4%) per annum); provided that unless the Loans have been
accelerated, interest, including the default rate of interest, shall only be due
and payable on the Interest Payment Dates.

         (c) Interest Payments. Interest on Loans shall be due and payable in
arrears on each Interest Payment Date. If an Interest Payment Date falls on a
date which is not a Business Day, such Interest Payment Date shall be deemed to
be the succeeding Business Day, except that in the case of Eurodollar Loans
where the succeeding Business Day falls in the succeeding calendar month, such
Interest Payment Date shall be the preceding Business Day.

3.2.     PLACE AND MANNER OF PAYMENTS.

         All payments of principal, interest, fees, expenses and other amounts
to be made by a Borrower under this Credit Agreement shall be made by such
Borrower unconditionally and without deduction for any counterclaim, defense,
recoupment or setoff and received not later than 2:00 p.m. on the date when due,
in Dollars and in immediately available funds, to the Administrative Agent at
its offices in New York City, New York. Payments received after such time shall
be deemed to have been received on the next Business Day. The Borrowers shall,
at the time they make any payment under this Credit Agreement, specify to the
Administrative Agent, the Loans, fees or other amounts payable by the Borrowers
hereunder to which such payment is to be applied (and in the event that they
fail to specify, or if such application would be inconsistent with the terms
hereof, the Administrative Agent shall, subject to Section 3.7, distribute such
payment to the Lenders in such manner as the Administrative Agent may deem
appropriate). The Administrative Agent will distribute any such payment to the
Lenders on the day received if such
                                      -27-


payment is received prior to 2:00 p.m.; otherwise the Administrative Agent will
distribute such payment to the Lenders on the next succeeding Business Day.
Whenever any payment hereunder shall be stated to be due on a day which is not a
Business Day, the due date thereof shall be extended to the next succeeding
Business Day (subject to accrual of interest and fees for the period of such
extension), except that in the case of Eurodollar Loans, if the extension would
cause the payment to be made in the next following calendar month, then such
payment shall instead be made on the next preceding Business Day.

3.3.     PAYMENTS.

         (a) Voluntary Prepayments. The Borrowers shall have the right to prepay
Term Loans, in whole or in part from time to time without premium or penalty;
provided, however, that (i) Eurodollar Loans may only be prepaid on three
Business Days' prior written notice to the Administrative Agent and any
prepayment of Eurodollar Loans will be subject to Section 3.13, (ii) (x) in the
case of Eurodollar Loans, each such partial prepayment shall be in the minimum

thereof, or (y) in the case of Base Rate Loans, each such partial prepayment
shall be in the minimum principal amount of $500,000 and integral multiples of
$100,000 in excess thereof.

         (b) Mandatory Prepayments.

                  (i) In the event one or more Capital Markets Transactions
         consisting of the issuance of equity (including pursuant to any
         over-allotment of shares granted to the underwriters of any such equity
         offering) is consummated after the date hereof, 100% of the net
         proceeds therefrom shall be applied by the Borrowers to permanently
         reduce the Term Loans outstanding.

                  (ii) In the event one or more Capital Markets Transactions
         consisting of the issuance of publicly registered (144A or otherwise)
         debt securities or any secured or unsecured debt financings (other than
         pursuant to a refinancing of existing indebtedness of the Borrowers but
         including any proceeds in excess of such amount being refinanced) are
         consummated, 100% of the net proceeds therefrom shall be applied by the
         Borrowers to permanently reduce the Term Loans outstanding.

                  (iii) In the event one or more Capital Markets Transactions
         consisting of the issuance of privately placed, non-144A or 144A (with
         no registration rights) debt securities is consummated in excess of
         $113 million, 100% of the net proceeds in excess of such $113 million
         shall be applied by the Borrowers to permanently reduce the Term Loans
         outstanding.

         (c) Application of Prepayments. All amounts required to be paid
pursuant to Section 3.3(b) shall be applied first to Base Rate Loans and then to
Eurodollar Loans. Amounts prepaid on account of Term Loans may not be
reborrowed. All prepayments hereunder shall be subject to Section 3.13.

                                      -28-


3.4.     FEES.

         (a) Administrative Fees. The Borrowers agree to pay to the
Administrative Agent, for its own account, an annual fee as agreed to between
the Borrowers and the Administrative Agent in the Fee Letter.

3.5.     PAYMENT IN FULL AT MATURITY.

         On the Maturity Date, the entire outstanding principal balance of all
Term Loans, together with accrued but unpaid interest and all other sums owing
with respect thereto, shall be due and payable in cash in full, unless
accelerated sooner pursuant to Section 9.2.

3.6.     COMPUTATIONS OF INTEREST AND FEES.

         (a) Except for Base Rate Loans bearing interest based on the Prime
Rate, which shall be calculated on the basis of a 365 or 366 day year as the
case may be, all computations of interest and fees hereunder shall be made on
the basis of the actual number of days elapsed over a year of 360 days. Interest
shall accrue from and include the date of borrowing (or continuation or
conversion) but exclude the date of payment.

         (b) It is the intent of the Lenders and the Credit Parties to conform
to and contract in strict compliance with applicable usury law from time to time
in effect. All agreements between the Lenders and the Credit Parties are hereby
limited by the provisions of this paragraph which shall override and control all
such agreements, whether now existing or hereafter arising and whether written
or oral. In no way, nor in any event or contingency (including but not limited
to prepayment or acceleration of the maturity of any obligation), shall the
interest taken, reserved, contracted for, charged, or received under this Credit
Agreement, under the Notes or otherwise, exceed the maximum nonusurious amount
permissible under applicable law. If, from any possible construction of any of
the Credit Documents or any other document, interest would otherwise be payable
in excess of the maximum nonusurious amount, any such construction shall be
subject to the provisions of this paragraph and such interest shall be
automatically reduced to the maximum nonusurious amount permitted under
applicable law, without the necessity of execution of any amendment or new
document. If any Lender shall ever receive anything of value which is
characterized as interest on the Loans under applicable law and which would,
apart from this provision, be in excess of the maximum lawful amount, an amount
equal to the amount which would have been excessive interest shall, without
penalty, be applied to the reduction of the principal amount owing on the Loans
and not to the payment of interest, or refunded to the Credit Parties or the
other payor thereof if and to the extent such amount which would have been
excessive exceeds such unpaid principal amount of the Loans. The right to demand
payment of the Loans or any other indebtedness evidenced by any of the Credit
Documents does not include the right to receive any interest which has not
otherwise accrued on the date of such demand, and the Lenders do not intend to
charge or receive any unearned interest in the event of such demand. All
interest paid or agreed to be paid to the Lenders with respect to the Loans
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated, and spread throughout the full stated term (including any renewal or
extension) of the Loans so that the amount of interest on account of such
indebtedness does not exceed the maximum nonusurious amount permitted by
applicable law.

                                      -29-


3.7.     PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

         (a) Loans. Each Term Loan borrowing, each payment or prepayment of
principal of any Term Loan, each payment of fees (other than administrative fees
payable pursuant to Section 3.4), and each conversion or continuation of any
Term Loan, shall (except as otherwise provided in Section 3.10) be allocated pro
rata among the Lenders in accordance with the respective Term Loan Commitment
Percentages of the Lenders (or, if the Commitments of the Lenders have expired
or been terminated, in accordance with the respective principal amounts of the
outstanding Loans of the Lenders); provided that, if any Lender shall have
failed to pay its applicable pro rata share of any Term Loan, then any amount to
which such Lender would otherwise be entitled pursuant to this Section 3.7 shall
instead be payable to the Administrative Agent until the share of such Loan not
funded by such Lender has been repaid; provided further, that in the event any
amount paid to any Lender pursuant to this Section 3.7 is rescinded or must
otherwise be returned by the Administrative Agent, each Lender shall, upon the
request of the Administrative Agent, repay to the Administrative Agent the
amount so paid to such Lender, with interest for the period commencing on the
date such payment is returned by the Administrative Agent until the date the
Administrative Agent receives such repayment at a rate per annum equal to,
during the period to but excluding the date two Business Days after such
request, the Federal Funds Rate, and thereafter, at the Base Rate plus two
percent (2%) per annum.

         (b) Sharing of Payments. The Lenders agree among themselves that,
except to the extent otherwise provided herein, in the event that any Lender
shall obtain payment in respect of any Loan or any other obligation owing to
such Lender under this Credit Agreement through the exercise of a right of
setoff, banker's lien or counterclaim, or pursuant to a secured claim under
Section 506 of the Bankruptcy Code or other security or interest arising from,
or in lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means
(other than in connection with an assignment pursuant to Section 3.14 or Section
11.3), in excess of its pro rata share of such payment as provided for in this
Credit Agreement, such Lender shall promptly pay in cash or purchase from the
other Lenders a participation in such Loans and other obligations in such
amounts, and make such other adjustments from time to time, as shall be
equitable to the end that all Lenders share such payment in accordance with
their respective ratable shares as provided for in this Credit Agreement. The
Lenders further agree among themselves that if payment to a Lender obtained by
such Lender through the exercise of a right of setoff, banker's lien,
counterclaim or other event as aforesaid shall be rescinded or must otherwise be
restored, each Lender which shall have shared the benefit of such payment shall,
by payment in cash or a repurchase of a participation theretofore sold, return
its share of that benefit (together with its share of any accrued interest
payable with respect thereto) to each Lender whose payment shall have been
rescinded or otherwise restored. The Credit Parties agree that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including setoff, banker's lien or counterclaim,
with respect to such participation as fully as if such Lender were a holder of
such Loan or other obligation in the amount of such participation. Except as
otherwise expressly provided in this Credit Agreement, if any Lender shall fail
to remit to the Administrative Agent or any other Lender an amount payable by
such Lender to the Administrative Agent or such other Lender pursuant to this
Credit Agreement on the date when such amount is due, such payments

                                      -30-


shall be made together with interest thereon for each date from the date such
amount is due until the date such amount is paid to the Administrative Agent or
such other Lender at a rate per annum equal to the Federal Funds Rate. If under
any applicable bankruptcy, insolvency or other similar law, any Lender receives
a secured claim in lieu of a setoff to which this Section 3.7 applies, such
Lender shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Lenders under this
Section 3.7 to share in the benefits of any recovery on such secured claim.

3.8.     CAPITAL ADEQUACY.

         If, after the date hereof, any Lender has determined that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender, or its parent corporation, with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's (or parent corporation's)
capital or assets as a consequence of its commitments or obligations hereunder
to a level below that which such Lender, or its parent corporation, could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's (or parent corporation's) policies with respect to
capital adequacy), then, upon notice from such Lender to the Borrowers and the
Administrative Agent, the Borrowers shall be obligated to pay to such Lender
such additional amount or amounts as will compensate such Lender (or parent
corporation) on an after-tax basis (after taking into account applicable
deductions and credits in respect of the amount indemnified) for such reduction.
Each determination by any such Lender of amounts owing under this Section shall,
absent manifest error, be conclusive and binding on the parties hereto. This
covenant shall survive the termination of this Credit Agreement and the payment
of the Loans and all other amounts payable hereunder.

3.9.     INABILITY TO DETERMINE INTEREST RATE.

         If prior to the first day of any Interest Period, the Administrative
Agent shall have determined in good faith (which determination shall be
conclusive and binding upon the Borrowers) that, by reason of circumstances
affecting the relevant market, adequate and reasonable means do not exist for
ascertaining the Adjusted Eurodollar Rate or the Eurodollar Rate for such
Interest Period, the Administrative Agent shall give telecopy or telephonic
notice thereof to the Borrowers and the Lenders as soon as practicable
thereafter, and will also give prompt written notice to the Borrowers and the
Lenders when such conditions no longer exist. If such notice is given (a) any
Eurodollar Loans requested to be made on the first day of such Interest Period
shall be made as Base Rate Loans and (b) any Loans that were to have been
converted on the first day of such Interest Period to or continued as Eurodollar
Loans shall be converted to or continued as Base Rate Loans. Until such notice
has been withdrawn by the Administrative Agent, no further Eurodollar Loans
shall be made or continued as such, nor shall the Borrowers have the right to
convert Base Rate Loans to Eurodollar Loans.

                                      -31-


3.10.    ILLEGALITY.

         Notwithstanding any other provision herein, if the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
occurring after the Closing Date shall make it unlawful for any Lender to make
or maintain Eurodollar Loans as contemplated by this Credit Agreement, (a) such
Lender shall promptly give written notice of such circumstances to the Borrowers
and the Administrative Agent (which notice shall be promptly withdrawn whenever
such circumstances no longer exist), (b) the commitment of such Lender hereunder
to make Eurodollar Loans, continue Eurodollar Loans as such and convert a Base
Rate Loan to Eurodollar Loans shall forthwith be cancelled and, until such time
as it shall no longer be unlawful for such Lender to make or maintain Eurodollar
Loans, such Lender shall then have a commitment only to make a Base Rate Loan
when a Eurodollar Loan is requested and (c) such Lender's Loans then outstanding
as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans
on the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrowers shall pay to
such Lender such amounts, if any, as may be required pursuant to Section 3.13;
provided that no such payments shall be required if the conversion of a
Eurodollar Loan occurs within 30 days of the last day of the Interest Period of
such Eurodollar Loan.

3.11.    REQUIREMENTS OF LAW.

         If the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof applicable to any Lender, or compliance by
any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority, in each case made
subsequent to the Closing Date (or, if later, the date on which such Lender
becomes a Lender):

         (a) shall subject such Lender to any tax of any kind whatsoever with
respect to any Eurodollar Loans made by it, or its obligation to make Eurodollar
Loans, or change the basis of taxation of payments to such Lender in respect
thereof (except for Non-Excluded Taxes covered by Section 3.12 (including
Non-Excluded Taxes imposed solely by reason of any failure of such Lender to
comply with its obligations (if any) under Section 3.12(b)) and changes in taxes
measured by or imposed upon the overall net income, or franchise tax (imposed in
lieu of such net income tax), of such Lender or its applicable lending office,
branch, or any Affiliate thereof);

         (b) shall impose, modify or hold applicable any reserve, special
deposit, compulsory loan or similar requirement against assets held by, deposits
or other liabilities in or for the account of, advances, loans or other
extensions of credit by, or any other acquisition of funds by, any office of
such Lender which is not otherwise included in the determination of the Adjusted
Eurodollar Rate hereunder; or

         (c) shall impose on such Lender any other condition (excluding any tax
of any kind whatsoever);

                                      -32-


and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Loans or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, upon notice to the Borrowers from such
Lender, through the Administrative Agent, in accordance herewith, the Borrowers
shall be obligated to promptly pay such Lender, upon its demand, any additional
amounts necessary to compensate such Lender on an after-tax basis (after taking
into account applicable deductions and credits in respect of the amount
indemnified) for such increased cost or reduced amount receivable, provided
that, in any such case, the Borrowers may elect to convert the Eurodollar Loans
made by such Lender hereunder to Base Rate Loans by giving the Administrative
Agent at least one Business Day's notice of such election, in which case the
Borrowers shall promptly pay to such Lender, upon demand, without duplication,
such amounts, if any, as may be required pursuant to Section 3.13. If any Lender
becomes entitled to claim any additional amounts pursuant to this Section 3.11,
it shall provide prompt notice thereof to the Borrowers, through the
Administrative Agent, certifying (x) that one of the events described in this
Section 3.11 has occurred and describing in reasonable detail the nature of such
event, (y) as to the increased cost or reduced amount resulting from such event
and (z) as to the additional amount demanded by such Lender and a reasonably
detailed explanation of the calculation thereof. Such a certificate as to any
additional amounts payable pursuant to this Section 3.11 submitted by such
Lender, through the Administrative Agent, to the Borrowers shall be conclusive
and binding on the parties hereto in the absence of manifest error. This
covenant shall survive the termination of this Credit Agreement and the payment
of the Loans and all other amounts payable hereunder.

3.12.    TAXES.

         (a) Except as provided below in this Section 3.12, all payments made by
the Borrowers under this Credit Agreement and any Notes shall be made free and
clear of, and without deduction or withholding for or on account of, any present
or future income, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, now or hereafter imposed, levied, collected,
withheld or assessed by any court, or governmental body, agency or other
official, excluding taxes measured by or imposed upon the overall net income of
any Lender or its applicable lending office, or any branch or Affiliate thereof,
and all franchise taxes, branch taxes, taxes on doing business or taxes on the
overall capital or net worth of any Lender or its applicable lending office, or
any branch or Affiliate thereof, in each case imposed in lieu of net income
taxes: (i) by the jurisdiction under the laws of which such Lender, applicable
lending office, branch or Affiliate is organized or is located, or in which its
principal executive office is located, or any nation within which such
jurisdiction is located or any political subdivision thereof; or (ii) by reason
of any connection between the jurisdiction imposing such tax and such Lender,
applicable lending office, branch or Affiliate other than a connection arising
solely from such Lender having executed, delivered or performed its obligations,
or received payment under or enforced, this Credit Agreement or any Notes. If
any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions
or withholdings ("Non-Excluded Taxes") are required to be withheld from any
amounts payable to the Administrative Agent or any Lender hereunder or under any
Notes, (a) the amounts so payable to the Administrative Agent or such Lender
shall be increased to the extent necessary to yield to the Administrative Agent
or such Lender (after payment of all Non-Excluded Taxes) interest on any such
other amounts payable hereunder at the rates or in the amounts specified in this
Credit Agreement and any Notes, provided, however, that the Borrowers shall be
entitled to deduct and withhold any Non-Excluded Taxes and shall not be required
to increase any such amounts payable to any Lender that is not organized under
the laws of the United States of America or a state thereof if such Lender fails
to comply with the requirements of paragraph (b) of

                                      -33-


this Section 3.12 whenever any Non-Excluded Taxes are payable by the Borrowers,
and (b) as promptly as possible after request therefor the Borrowers shall send
to the Administrative Agent for its own account or for the account of such
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrowers showing payment thereof. If the Borrowers fail to pay
any Non-Excluded Taxes when due to the appropriate taxing authority or fail to
remit to the Administrative Agent the required receipts or other required
documentary evidence, the Borrowers shall indemnify the Administrative Agent and
any Lender for any incremental taxes, interest or penalties that may become
payable by the Administrative Agent or any Lender as a result of any such
failure. The agreements in this subsection shall survive the termination of this
Credit Agreement and the payment of the Loans and all other amounts payable
hereunder.

         (b) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof shall:

                  (i) (A) on or before the date of any payment by the Borrowers
         under this Credit Agreement or Notes to such Lender, deliver to the
         Borrowers and the Administrative Agent (x) two duly completed copies of
         United States Internal Revenue Service Form W8-BEN or W8-ECI, or
         successor applicable form, as the case may be, certifying that it is
         entitled to receive payments under this Credit Agreement and any Notes
         without deduction or withholding of any United States federal income
         taxes and (y) an Internal Revenue Service Form W-8 or W-9, or successor
         applicable form, as the case may be, certifying that it is entitled to
         an exemption from United States backup withholding tax;

                           (B) deliver to the Borrowers and the Administrative
                  Agent two further copies of any such form or certification on
                  or before the date that any such form or certification expires
                  or becomes obsolete and after the occurrence of any event
                  requiring a change in the most recent form previously
                  delivered by it to the Borrowers; and

                           (C)      obtain such extensions of time for filing
                  and complete such forms or certifications as may reasonably be
                  requested by the Borrowers or the Administrative Agent; or

                  (ii) in the case of any such Lender that is not a "bank"
         within the meaning of Section 881(c)(3)(A) of the Internal Revenue
         Code, such Lender shall (a) represent to the Borrowers (for the benefit
         of the Borrowers and the Administrative Agent) that it is not a bank
         within the meaning of Section 881(c)(3)(A) of the Internal Revenue
         Code, (b) furnish to the Borrowers, on or before the date of any
         payment by the Borrowers, with a copy to the Administrative Agent, two
         accurate and complete original signed copies of Internal Revenue
         Service Form W-8, or successor applicable form certifying to such
         Lender's legal entitlement at the date of such certificate to an
         exemption from U.S. withholding tax under the provisions of Section
         881(c) of the Internal Revenue Code with respect to payments to be made
         under this Credit Agreement and any Notes (and to deliver to the
         Borrowers and the Administrative Agent two further copies of such form
         on or before the date it expires or becomes obsolete and after

                                      -34-


                  the occurrence of any event requiring a change in the most
                  recently provided form and, if necessary, obtain any
                  extensions of time reasonably requested by the Borrowers or
                  the Administrative Agent for filing and completing such
                  forms), and (c) agree, to the extent legally entitled to do
                  so, upon reasonable request by the Borrowers, to provide to
                  the Borrowers (for the benefit of the Borrowers and the
                  Administrative Agent) such other forms as may be reasonably
                  required in order to establish the legal entitlement of such
                  Lender to an exemption from withholding with respect to
                  payments under this Credit Agreement and any Notes.

         Notwithstanding the above, if any change in treaty, law or regulation
         has occurred after the date such Person becomes a Lender hereunder
         which renders all such forms inapplicable or which would prevent such
         Lender from duly completing and delivering any such form with respect
         to it and such Lender so advises the Borrowers and the Administrative
         Agent then such Lender shall be exempt from such requirements. Each
         Person that shall become a Lender or a participant of a Lender pursuant
         to Section 11.3 shall, upon the effectiveness of the related transfer,
         and if applicable, be required to provide all of the forms,
         certifications and statements required pursuant to this subsection (b);
         provided that in the case of a participant of a Lender, the obligations
         of such participant of a Lender pursuant to this subsection (b) shall
         be determined as if such participant of a Lender were a Lender except
         that such participant of a Lender shall furnish all such required
         forms, certifications and statements to the Lender from which the
         related participation shall have been purchased.

3.13.    COMPENSATION.

         The Borrowers promise to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur as a
consequence of (a) default by the Borrowers in making a borrowing of, conversion
into or continuation of Eurodollar Loans, after the Borrowers have given a
notice requesting the same in accordance with the provisions of this Credit
Agreement, (b) default by the Borrowers in making any prepayment of a Eurodollar
Loan after the Borrowers have given a notice thereof in accordance with the
provisions of this Credit Agreement and (c) any continuation, conversion,
payment or prepayment of Eurodollar Loans on a day which is not the last day of
an Interest Period with respect thereto. Such indemnification shall be
calculated by the Administrative Agent and shall include, without limitation, an
amount equal to (i) the amount of interest which would have accrued on the
amount so prepaid, or not so borrowed, converted or continued, for the period
from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of the applicable Interest Period (or, in the case of a
failure to borrow, convert or continue, the Interest Period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Eurodollar Loans provided for herein minus (ii) the amount of
interest which would have accrued to such Lender on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank
Eurodollar market. The agreements in this Section 3.13 shall survive the
termination of this Credit Agreement and the payment of the Loans and all other
amounts payable hereunder. Notwithstanding the foregoing, any prepayment of a
Eurodollar Loan made hereunder (as a result of a mandatory requirement of this
Credit Agreement) within thirty (30) days of the end of the Interest Period with
respect to such Eurodollar Loan, shall not be subject to this Section 3.13.

                                      -35-


3.14.    MITIGATION; MANDATORY ASSIGNMENT.

         Each Lender shall use reasonable efforts to avoid or mitigate any
increased cost or suspension of the availability of an interest rate under
Sections 3.8 through 3.13 inclusive to the greatest extent practicable
(including transferring the Loans to another lending office or one of its
Affiliates) unless, in the opinion of such Lender, such efforts would be likely
to have an adverse effect upon it. In the event a Lender makes a request to the
Borrowers for additional payments in accordance with Section 3.8, 3.9, 3.10,
3.11, 3.12 or 3.13 or a Lender becomes a Defaulting Lender, then, provided that
no Default or Event of Default has occurred and is continuing at such time, the
Borrowers may, at their own expense (such expense to include any transfer fee
payable to the Administrative Agent under Section 11.3(b) and any expense
pursuant to Section 3.13), and in their sole discretion, require such Lender to
transfer and assign in whole (but not in part), without recourse (in accordance
with and subject to the terms and conditions of Section 11.3(b)), all of its
interests, rights and obligations under this Credit Agreement to an Eligible
Assignee which shall assume such assigned obligations (which Eligible Assignee
may be another Lender, if a Lender accepts such assignment); provided that (a)
such assignment shall not conflict with any law, rule or regulation or order of
any court or other Governmental Authority and (b) the Borrowers or such assignee
shall have paid to the assigning Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the portion of
the Loans hereunder held by such assigning Lender and all other amounts owed to
such assigning Lender hereunder, including amounts owed pursuant to Sections 3.8
through 3.13. Notwithstanding such assignment, and without limiting any other
provision of this Credit Agreement, such assigning Lender shall continue to
benefit from the provisions of Sections 3.8, 3.11, 3.12 and 11.5 with respect to
the period before the effectiveness of such assignment.

                                   SECTION 4

                                   GUARANTY

4.1.     GUARANTY OF PAYMENT.

         Subject to Section 4.7, each of the Guarantors hereby, jointly and
severally, absolutely, irrevocably and unconditionally guarantees to each Lender
the prompt payment of the Obligations in cash in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration or otherwise). This
Guaranty is a guaranty of payment and not of collection and is a continuing
guaranty and shall apply to all Obligations whenever arising.

4.2.     OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors hereunder are absolute, irrevocable
and unconditional, irrespective of the value, genuineness, validity, regularity
or enforceability of any of the Credit Documents or any other agreement or
instrument referred to therein, to the fullest extent permitted by applicable
law, irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor.
Each Guarantor agrees that this Guaranty may be enforced by the Lenders without
the necessity at any time of resorting to or exhausting any other security or
collateral and without the necessity at any time of having recourse to the Notes
or any other of the Credit Documents or any collateral, if any, hereafter


                                      -36-


securing the Obligations or otherwise and each Guarantor hereby waives the right
to require the Lenders to proceed against the Borrowers or any other Person
(including a co-guarantor) or to require the Lenders to pursue any other remedy
or enforce any other right. Each Guarantor further agrees that it shall have no
right of subrogation, indemnity, reimbursement or contribution against the
Borrowers or any other Guarantor of the Obligations for amounts paid under this
Guaranty until such time as the Lenders have been paid in full, all Commitments
under this Credit Agreement have been terminated and no Person or Governmental
Authority shall have any right to request any return or reimbursement of funds
from the Lenders in connection with monies received under the Credit Documents.
Each Guarantor further agrees that nothing contained herein shall prevent the
Lenders from suing on the Notes or any of the other Credit Documents or
foreclosing any security interest in or Lien on any collateral, if any, securing
the Obligations or from exercising any other rights available to any of them
under this Credit Agreement, the Notes, any of the other Credit Documents, or
any other instrument of security, if any, and the exercise of any of the
aforesaid rights and the completion of any foreclosure proceedings shall not
constitute a discharge of any of any Guarantor's obligations hereunder; it being
the purpose and intent of each Guarantor that its obligations hereunder shall be
absolute, independent, irrevocable and unconditional under any and all
circumstances. Neither any Guarantor's obligations under this Guaranty nor any
remedy for the enforcement thereof shall be impaired, modified, changed or
released in any manner whatsoever by an impairment, modification, change,
release or limitation of the liability of the Borrowers or by reason of the
bankruptcy or insolvency of the Borrowers. Each Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof of reliance of by the Administrative Agent or any Lender
upon this Guaranty or acceptance of this Guaranty. The Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon this Guaranty. All
dealings between the Borrowers and any of the Guarantors, on the one hand, and
the Administrative Agent and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon this
Guaranty. The Guarantors further agree to all rights of set-off as set forth in
Section 11.2.

4.3.     MODIFICATIONS.

         Each Guarantor agrees that (a) all or any part of the security now or
hereafter held for the Obligations, if any, may be exchanged, compromised or
surrendered from time to time; (b) the Lenders shall not have any obligation to
protect, perfect, secure or insure any such security interests, liens or
encumbrances now or hereafter held, if any, for the Obligations or the
properties subject thereto; (c) the time or place of payment of the Obligations
may be changed or extended, in whole or in part, to a time certain or otherwise,
and may be renewed or accelerated, in whole or in part; (d) the Borrowers and
any other party liable for payment under the Credit Documents may be granted
indulgences generally; (e) any of the provisions of the Notes or any of the
other Credit Documents may be modified, amended or waived; (f) any party
(including any co-guarantor) liable for the payment thereof may be granted
indulgences or be released; and (g) any deposit balance for the credit of the
Borrowers or any other party liable for the payment of the Obligations or liable
upon any security therefor may be released, in whole or in part, at, before or
after the stated, extended or accelerated maturity of the Obligations, all
without notice to or further assent by such Guarantor, which shall remain bound
thereon, notwithstanding any such exchange, compromise, surrender, extension,
renewal, acceleration, modification, indulgence or release.

                                      -37-

all extensions of credit to the Borrowers by the Lenders; (b) presentment and
demand for payment or performance of any of the Obligations; (c) protest and
notice of dishonor or of default (except as specifically required in this Credit
Agreement) with respect to the Obligations or with respect to any security
therefor; (d) notice of the Lenders obtaining, amending, substituting for,
releasing, waiving or modifying any security interest, lien or encumbrance, if
any, hereafter securing the Obligations, or the Lenders' subordinating,
compromising, discharging or releasing such security interests, liens or
encumbrances, if any; (e) all other notices to which such Guarantor might
otherwise be entitled; and (f) the benefit of any laws that exonerate or limit
the liability of guarantors or sureties, and any defenses provided by these
laws.

4.5.     REINSTATEMENT.

         The obligations of the Guarantors under this Guaranty shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Obligations is rescinded or must be
otherwise restored by any holder of any of the Obligations, whether as a result
of any proceedings in bankruptcy or reorganization or otherwise, and each
Guarantor agrees that it will indemnify the Administrative Agent and each Lender
on demand for all reasonable costs and expenses (including, without limitation,
reasonable fees of counsel) incurred by the Administrative Agent or such Lender
in connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment
constituted a preference, fraudulent transfer or similar payment under any
bankruptcy, insolvency or similar law.

4.6.     REMEDIES.

         The Guarantors agree that, as between the Guarantors, on the one hand,
and the Administrative Agent and the Lenders, on the other hand, the Obligations
may be declared to be forthwith due and payable as provided in Section 9 (and
shall be deemed to have become automatically due and payable in the
circumstances provided in Section 9) notwithstanding any stay, injunction or
other prohibition preventing such declaration (or preventing such Obligations
from becoming automatically due and payable) as against any other Person and
that, in the event of such declaration (or such Obligations being deemed to have
become automatically due and payable), such Obligations (whether or not due and
payable by any other Person) shall forthwith become due and payable by the
Guarantors.

4.7.     LIMITATION OF GUARANTY.

         It is the intention and agreement of the Guarantors, the Administrative
Agent and the Lenders that the obligations of each Guarantor hereunder shall be
valid and enforceable against each Guarantor to the maximum extent permitted by
applicable law. Notwithstanding any provision to the contrary contained herein
or in any of the other Credit Documents, to the extent the obligations of any
Guarantor shall be adjudicated or declared to be invalid or unenforceable for
any reason (including, without limitation, because of any applicable state or
federal law relating to fraudulent conveyances or transfers) then the
obligations of such Guarantor hereunder shall be limited to the maximum amount
that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

                                      -38-


4.8.     RIGHTS OF CONTRIBUTION.

         The Credit Parties agree among themselves that, in connection with
payments made hereunder, each Credit Party shall have contribution rights
against the other Credit Parties as permitted under applicable law. Such
contribution rights shall be subordinate and subject in right of payment to the
obligations of the Credit Parties under the Credit Documents and no Credit Party
shall exercise such rights of contribution until all the Obligations have been
paid in full and the Commitments terminated.

maintained, operated, and funded in compliance with its own terms and in

Single Employer Plan, as of the last annual valuation date prior to the date on
which this representation is made or deemed made (determined, in each case, in

ERISA or Section 4975 of the Code) or breach of fiduciary responsibility has
occurred with respect to a Plan which has subjected or may subject any Credit
Party, any Subsidiary of a Credit Party or any ERISA Affiliate to any liability
under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Code,
or under any agreement or other instrument pursuant to which any Credit Party,
any Subsidiary of a Credit Party or any ERISA Affiliate has agreed or is
required to indemnify any person against any such liability.

         (e) No Credit Party, Subsidiary of a Credit Party or ERISA Affiliate
has material liability with respect to "expected post-retirement benefit
obligations" within the meaning of the Financial Accounting Standards Board
Statement 106. Each Plan which is a welfare plan (as defined in Section 3(1) of
ERISA) to which Sections 601-609 of ERISA and Section 4980B of the Code apply
has been administered in compliance in all material respects with such sections.

shall notify the Administrative Agent and promptly thereafter (but in any event
within thirty (30) days after such event): (a) execute a Joinder Agreement in

         (a) Termination of Commitments. Declare the Commitments terminated
whereupon the Commitments shall be immediately terminated.

accrued interest in respect of all Loans, and any and all other indebtedness or

action by the Administrative Agent or the Lenders, which notice or other action
is expressly waived by the Credit Parties.

Notwithstanding the fact that enforcement powers reside primarily with the

separate right of payment and shall be considered a separate "creditor" holding
a separate "claim" within the meaning of Section 101(5) of the Bankruptcy Code
or any other insolvency statute.

9.3.     ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.

         Notwithstanding any other provisions of this Credit Agreement, after

collected or received by the Administrative Agent or any Lender on account of
amounts outstanding under any of the Credit Documents shall be paid over or
delivered as follows:

                  FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Administrative Agent in connection with enforcing the rights of
         the Lenders under the Credit Documents;

                  SECOND, to payment of any fees owed to the Administrative
         Agent;

                  THIRD, to the payment of all reasonable out-of-pocket costs
         and expenses, (including, without limitation, reasonable attorneys'
         fees) of each of the Lenders in connection with enforcing its rights
         under the Credit Documents;

                  FOURTH, to the payment of all accrued fees and interest
         payable to the Lenders hereunder;

                  FIFTH, to the payment of the outstanding principal amount of
         the Loans, pro rata, as set forth below;

                  SIXTH, to all other Obligations which shall have become due
         and payable under the Credit Documents and not repaid pursuant to
         clauses "FIRST" through "FIFTH" above; and

                  SEVENTH, to the payment of the surplus, if any, to whoever may
         be lawfully entitled to receive such surplus.

                                      -63-


In carrying out the foregoing, (a) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category and (b) each of the Lenders shall receive an amount equal to
its pro rata share (based on the proportion that the then outstanding Loans held
by such Lender bears to the aggregate then outstanding Loans) of amounts
available to be applied pursuant to clauses "THIRD", "FOURTH," "FIFTH," and
"SIXTH" above.

obligations or liabilities shall be read into this Credit Agreement or any of
the other Credit Documents, or shall otherwise exist against the Administrative
Agent. The provisions of this Section are solely for the benefit of the
Administrative Agent and the Lenders and none of the Credit Parties shall have
any rights as a third party beneficiary of the provisions hereof. In performing
its functions and duties under this Credit Agreement and the other Credit
Documents, the Administrative Agent shall act solely as an agent of the Lenders
and does not assume and shall not be deemed to have assumed any obligation or
relationship of agency or trust with or for any Credit Parties.

10.2.    DELEGATION OF DUTIES.

         The Administrative Agent may execute any of its duties hereunder or
under the other Credit Documents by or through agents or attorneys-in-fact and
shall be entitled to advice of counsel concerning all matters pertaining to such
duties. The Administrative Agent shall not be responsible for the negligence or
misconduct of any agents or attorneys-in-fact selected by it with reasonable
care.

10.3.    EXCULPATORY PROVISIONS.

         No Agent-Related Person shall be (a) liable for any action lawfully
taken or omitted to be taken by it under or in connection herewith or in
connection with any of the other Credit Documents (except for such Person's own
gross negligence or willful misconduct) or (b) responsible in any manner to any
of the Lenders for any recitals, statements, representations or warranties made
by any of the Credit Parties contained herein or in any of the other Credit
Documents or in any certificate, report, document, financial statement or other
written or oral statement referred to or provided for in, or received by an
Agent-Related Person under or in

                                      -64-


connection herewith or in connection with the other Credit Documents, or the
enforceability or sufficiency of this Credit Agreement or any of the other
Credit Documents, or for any failure of the Credit Parties to perform their
obligations hereunder or thereunder. No Agent-Related Person shall be
responsible to any Lender for the effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Credit Agreement, or any
of the other Credit Documents or for any representations, warranties, recitals
or statements made herein or therein or made by the Credit Parties in any
written or oral statement or in any financial or other statements, instruments,
reports, certificates or any other documents in connection herewith or therewith
furnished or made by an Agent-Related Person to the Lenders or by or on behalf
of the Credit Parties to an Agent-Related Person or any Lender or be required to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, provisions, covenants or agreements contained herein or therein or
as to the use of the proceeds of the Loans or of the existence or possible
existence of any Default or Event of Default or to inspect the properties, books
or records of the Credit Parties. No Agent-Related Person is a trustee for the
Lenders or owes any fiduciary duty to the Lenders.

10.4.    RELIANCE ON COMMUNICATIONS.

         The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to any of the Credit Parties, independent accountants and
other experts selected by the Administrative Agent with reasonable care). The
Administrative Agent may deem and treat each Lender as the owner of its
interests hereunder for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Administrative
Agent in accordance with Section 11.3(b). The Administrative Agent shall be
fully justified in failing or refusing to take any action under this Credit
Agreement or under any of the other Credit Documents unless it shall first
receive such advice or concurrence of the Required Lenders (or, to the extent
provided in Section 11.6, all of the Lenders) as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense (other than any liability or expense resulting from
the gross negligence or willful misconduct of the Administrative Agent) which
may be incurred by it by reason of taking or continuing to take any such action.
The Agent-Related Persons shall in all cases be fully protected in acting, or in
refraining from acting, hereunder or under any of the other Credit Documents in
accordance with a request of the Required Lenders (or to the extent specifically
provided in Section 11.6, all the Lenders) and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders
(including their successors and assigns).

10.5.    NOTICE OF DEFAULT.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Lender or a Credit Party
referring to the applicable Credit Document, describing such Default or Event of
Default and stating that such notice is a "notice of default." In the event that
the Administrative Agent receives such a notice, or otherwise becomes aware of a
Default or Event of Default, the Administrative Agent shall give prompt notice
thereof to the Lenders. The Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by
the Required Lenders (or, to the extent provided in Section 11.6, all of the
Lenders).

                                      -65-


10.6.    NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that no Agent-Related Person has
made any representations or warranties to it and that no act by any
Agent-Related Person hereafter taken, including any review of the affairs of any
Credit Party, shall be deemed to constitute any representation or warranty by
any Agent-Related Person or any other Lender. Each Lender represents to the
Administrative Agent and the Arranger that it has, independently and without
reliance upon any Agent-Related Person or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, assets, operations, property, financial
and other conditions, prospects and creditworthiness of the Credit Parties and
made its own decision to make its Loans hereunder and enter into this Credit
Agreement. Each Lender also represents that it will, independently and without
reliance upon any Agent-Related Person or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Credit Agreement, and to make such investigation as it deems
necessary to inform itself as to the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Credit
Parties. Except for notices, reports and other documents expressly required to
be furnished to the Lenders by the Administrative Agent hereunder, no
Agent-Related Person shall have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations,
assets, property, financial or other conditions, prospects or creditworthiness
of the Credit Parties which may come into the possession of any Agent-Related
Person.

10.7.    INDEMNIFICATION.

         The Lenders agree to indemnify each Agent-Related Person (to the extent
not reimbursed by the Credit Parties and without limiting the obligation of the
Credit Parties to do so), ratably according to their respective Commitments (or
if the Commitments have expired or been terminated, in accordance with the
respective principal amounts of outstanding Loans of the Lenders), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including without limitation at any time
following payment in full of the Obligations) be imposed on, incurred by or
asserted against such Agent-Related Person in any way relating to or arising out
of this Credit Agreement or the other Credit Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by such
Agent-Related Person under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or willful
misconduct of such Agent-Related Person. If any indemnity furnished to the
Administrative Agent for any purpose shall, in the opinion of the Administrative
Agent, be insufficient or become impaired, the Administrative Agent may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity (except against its gross negligence or
willful misconduct) is furnished. The agreements in this Section 10.7 shall
survive the payment of the Obligations and all other amounts payable hereunder
and under the other Credit Documents.

                                      -66-


10.8.    ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.

         The Person serving as the Administrative Agent and its Affiliates may
make loans to, accept deposits from and generally engage in any kind of business
with the Credit Parties as though the Person serving as the Administrative Agent
were not the Administrative Agent hereunder. With respect to the Loans made, the
Person serving as the Administrative Agent shall have the same rights and powers
under this Credit Agreement as any Lender and may exercise the same as though it
were not the Administrative Agent, and the terms "Lender" and "Lenders" shall
include the Person serving as the Administrative Agent in its individual
capacity.

10.9.    SUCCESSOR AGENT.

         The Administrative Agent (a) may, at any time, resign upon twenty (20)
days written notice to the Lenders or (b) may be removed, with the consent of
the Borrowers, for willful misconduct or gross negligence by written notice from
the Required Lenders; provided that no consent of the Borrowers shall be
required during the existence and continuation of an Event of Default. Upon any
such resignation or removal, the Required Lenders shall have the right to
appoint a successor Administrative Agent. In the case of the Administrative
Agent's resignation or removal, if no successor Administrative Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within forty-five (45) days after the notice of resignation or
removal, then the retiring Administrative Agent shall select a successor
Administrative Agent provided such successor is a Lender hereunder or an
Eligible Assignee. If no such successor shall have been appointed by the
Administrative Agent, and shall have accepted such appointment, within
forty-five (45) days after such notice of resignation, such notice shall
nevertheless become effective and the Lenders shall perform all of the duties of
the Administrative Agent hereunder until such time, if any, as the Required
Lenders appoint a successor as provided above. Upon the acceptance of any
appointment as the Administrative Agent hereunder by a successor, if any, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring or removed
Administrative Agent, and the retiring or removed Administrative Agent shall be
discharged from its duties and obligations as the Administrative Agent, as
appropriate, under this Credit Agreement and the other Credit Documents and the
provisions of this Section 10.9 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was the Administrative Agent under
this Credit Agreement.

         JPMorgan Chase Bank, as syndication agent hereunder, may resign at any
time without any requirement that a successor syndication agent be appointed in
its stead.

                                   SECTION 11

                                 MISCELLANEOUS

11.1.    NOTICES.

         Except as otherwise expressly provided herein, all notices and other
communications shall have been duly given and shall be effective (a) when
delivered, (b) when transmitted via telecopy (or other facsimile device), (c)
the Business Day following the day on which the same has been delivered prepaid
or on an invoice arrangement to a reputable national overnight air courier
service, or (d) the third Business Day following the day on which the same is
sent by certified or registered mail, postage prepaid, in each case to the
respective parties at the address or telecopy numbers set forth on Schedule
11.1, or at such other address or numbers as such party may specify by written
notice to the other parties hereto.

11.2.    RIGHT OF SET-OFF.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default and the commencement of remedies described in
Section 9.2, each Lender is authorized at any time and from time to time,
without presentment, demand, protest or other notice of any kind (all of which
rights being hereby expressly waived), to set off and to appropriate and apply
any and all deposits (general or special) and any other indebtedness at any time
held or owing by such Lender (including, without limitation, branches, agencies
or Affiliates of such Lender wherever located) to or for the credit or the
account of any Credit Party against obligations and liabilities of such Credit
Party to the Lenders hereunder, under the Notes, the other Credit Documents or
otherwise, irrespective of whether the Administrative Agent or the Lenders shall
have made any demand hereunder and although such obligations, liabilities or
claims, or any of them, may be contingent or unmatured, and any such set-off
shall be deemed to have been made immediately upon the occurrence of an Event of
Default even though such charge is made or entered on the books of such Lender
subsequent thereto. The Credit Parties hereby agree that any Person purchasing a
participation in the Loans and Commitments hereunder pursuant to Section 11.3(c)
or 3.7(b) may exercise all rights of set-off with respect to its participation
interest as fully as if such Person were a Lender hereunder.

11.3. BENEFIT OF AGREEMENT.

(a) Generally. This Credit Agreement shall be binding upon and inure to the
benefit of and be enforceable by the respective successors and assigns of the
parties hereto; provided that none of the Credit Parties may assign and transfer
any of its interests (except as permitted by Section 8.4 or 8.5) without the
prior written consent of the Lenders (and any attempt at such assignment or
transfer without such consent shall be null and void); and provided further that
the rights of each Lender to transfer, assign or grant participations in its
rights and/or obligations hereunder shall be limited as set forth in subsections
(b) and (c) of this Section 11.3. Notwithstanding the above (including anything
set forth in subsections (b) and (c) of this Section 11.3), nothing herein shall
restrict, prevent or prohibit the Administrative Agent or any of its Affiliates
from granting any assignment or participation in any Loan under the terms of

                                      -68-


Section 11.3 hereof; provided, that the consent of the Administrative Agent and
the Borrowers shall not be required for the grant of such assignment or
participation, or shall restrict, prevent or prohibit any Lender from (A)
pledging or assigning a security interest in its rights hereunder or under its
Notes, if any, to secure obligations of such Lender, including any pledge or
assignment to a Federal Reserve Bank in support of borrowings made by such
Lender from such Federal Reserve Bank; provided that no such pledge or
assignment shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto, or
(B) granting assignments or participations (x) in such Lender's funded Loans
under the terms of Section 11.3 hereof; provided, that the consent of the
Administrative Agent and the Borrowers shall not be required for the grant of
such assignment or participation, (y) in such Lender's Loans and/or Commitments
hereunder to its parent company and/or to any other Affiliate of such Lender or
(z) to any existing Lender or Affiliate thereof.

         (b) Assignments. In addition to the assignments permitted by Section
11.3(a), each Lender may, with the prior written consent of the Borrowers and
the Administrative Agent (provided that no consent of the Borrowers shall be
required during the existence and continuation of an Event of Default), which
consent shall not be unreasonably withheld or delayed, assign all or a portion
of its rights and obligations hereunder pursuant to an assignment agreement
substantially in the form of Exhibit 11.3(b) to one or more Eligible Assignees;
provided that (i) any such assignment shall be in a minimum aggregate amount of
$1,000,000 of the Commitments (or the remaining amount of Commitments held by
such Lender) unless otherwise agreed by the Borrowers and Administrative Agent
to reduce such minimum amount and (ii) each such assignment shall be of a
constant, not varying, percentage of all of the assigning Lender's rights and
obligations under the Commitment being assigned. Any assignment hereunder shall
be effective upon satisfaction of the conditions set forth above and delivery to
the Administrative Agent of a duly executed assignment agreement. Upon the
effectiveness of any such assignment, the assignee shall become a "Lender" for
all purposes of this Credit Agreement and the other Credit Documents and, to the
extent of such assignment, the assigning Lender shall be relieved of its
obligations hereunder to the extent of the Loans and Commitment components being
assigned. The Borrowers agree that upon notice of any assignment to an assignee
that was not theretofore a Lender, they will promptly provide to such assignee a
new Note. Each Lender agrees that, in the event it assigns all of its Commitment
hereunder, it shall promptly return the Note or Note(s) executed by the
Borrowers in its favor.

         By executing and delivering an assignment agreement in accordance with
this Section 11.3(b), the assigning Lender thereunder and the assignee
thereunder shall be deemed to confirm to and agree with each other and the other
parties hereto as follows: (i) such assigning Lender warrants that it is the
legal and beneficial owner of the interest being assigned thereby free and clear
of any adverse claim and the assignee warrants that it is an Eligible Assignee;
(ii) except as set forth in clause (i) above, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Credit Agreement, any of the other Credit Documents or any other instrument or
document furnished pursuant hereto or thereto, or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Credit
Agreement, any of the other Credit Documents or any other instrument or document
furnished pursuant hereto or thereto or the financial condition of any Credit
Party or the performance or observance by any Credit Party of any of its
obligations under this Credit Agreement, any of the other Credit Documents or
any other

                                      -69-


instrument or document furnished pursuant hereto or thereto; (iii) such
assigning Lender and such assignee each represents and warrants that it is
legally authorized to enter into such assignment agreement; (iv) such assignee
confirms that it has received a copy of this Credit Agreement, the other Credit
Documents and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such assignment
agreement; (v) such assignee will independently and without reliance upon the
Administrative Agent, such assigning Lender or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Credit Agreement and the other Credit Documents; (vi) such assignee
appoints and authorizes the Administrative Agent to take such action on its
behalf and to exercise such powers under this Credit Agreement or any other
Credit Document as are delegated to the Administrative Agent by the terms hereof
or thereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all the obligations which by the terms of this Credit Agreement and the other
Credit Documents are required to be performed by it as a Lender.

         (c) Participations. In addition to the participations permitted by
Section 11.3(a), each Lender may, without the consent of, or notice to, the
Borrowers or the Administrative Agent, sell, transfer or grant participations in
all or any part of such Lender's interests and obligations hereunder; provided
that (i) such selling Lender shall remain a "Lender" for all purposes under this
Credit Agreement (such selling Lender's obligations under the Credit Documents
remaining unchanged) and the participant shall not constitute a Lender
hereunder, (ii) no such participant shall have, or be granted, rights to approve
any amendment or waiver relating to this Credit Agreement or the other Credit
Documents except to the extent any such amendment or waiver would (A) reduce the
principal of or rate of interest on or fees in respect of any Loans in which the
participant is participating or increase any Commitments with respect thereto,
or (b) postpone the date fixed for any payment of principal (including the
extension of the final maturity of any Loan or the date of any mandatory
prepayment), interest or fees in which the participant is participating, (iii)
sub-participations by the participant (except to an Affiliate of the
participant) shall be prohibited and (iv) any such participations shall be in a
minimum aggregate amount of $1,000,000 of the Commitments and in integral
multiples of $100,000 in excess thereof. In the case of any such participation,
the participant shall not have any rights under this Credit Agreement or the
other Credit Documents (the participant's rights against the selling Lender in
respect of such participation to be those set forth in the participation
agreement with such Lender creating such participation) and all amounts payable
by the Credit Parties hereunder shall be determined as if such Lender had not
sold such participation; provided, however, that such participant shall be
entitled to receive additional amounts under Sections 3.8, 3.11, 3.12 and 3.13
to the same extent that the Lender from which such participant acquired its
participation would be entitled to the benefit of such cost protection
provisions.

         (d) The Administrative Agent shall maintain at the Administrative
Agent's office at the Agency Services Address a copy of each assignment
agreement delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Commitments of, and principal amount of the
Loans owing to, each Lender pursuant to the terms hereof from time to time (the
"REGISTER"). The entries in the Register shall be conclusive absent manifest
error, and the Borrowers, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Credit Agreement, notwithstanding
notice to the contrary. The Register shall be available for inspection by the
Borrowers and any Lender, at any reasonable time and from time to time upon
reasonable prior notice.

                                      -70-


11.4.    NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Administrative Agent or any
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Credit Parties and the
Administrative Agent or any Lender shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, power or privilege hereunder or
under any other Credit Document preclude any other or further exercise thereof
or the exercise of any other right, power or privilege hereunder or thereunder.
The rights and remedies provided herein are cumulative and not exclusive of any
rights or remedies which the Administrative Agent or any Lender would otherwise
have. No notice to or demand on any Credit Party in any case shall entitle any
Credit Party to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Administrative Agent
or the Lenders to any other or further action in any circumstances without
notice or demand.

11.5.    PAYMENT OF EXPENSES; INDEMNIFICATION.

         The Credit Parties agree to: (a) pay all reasonable out-of-pocket costs
and expenses of (i) each Agent-Related Person in connection with (A) the
negotiation, preparation, execution and delivery, syndication and administration
of this Credit Agreement and the other Credit Documents and the documents and
instruments referred to therein (including, without limitation, the reasonable
fees and expenses of Paul, Hastings, Janofsky & Walker LLP, counsel to the
Administrative Agent) and (B) any amendment, waiver or consent relating hereto
and thereto including, but not limited to, any such amendments, waivers or
consents resulting from or related to any work-out, renegotiation or restructure
relating to the performance by the Credit Parties under this Credit Agreement,
and (ii) the Agent-Related Persons and the Lenders in connection with (A)
enforcement of the Credit Documents and the documents and instruments referred
to herein and therein, including, without limitation, in connection with any
such enforcement, the reasonable fees and disbursements of counsel for the
Agent-Related Persons and each of the Lenders, and (B) any bankruptcy or
insolvency proceeding of a Credit Party or any of its Subsidiaries, and (b)
indemnify the Agent-Related Persons, each Lender and its officers, directors,
employees, representatives, Affiliates and agents from and hold each of them
harmless against any and all losses, liabilities, claims, damages or expenses
incurred by any of them as a result of, or arising out of, or in any way related
to, or by reason of, any investigation, litigation or other proceeding (whether
or not any Agent-Related Person or any Lender is a party thereto) related to (i)
the entering into and/or performance of any Credit Document or the use of
proceeds of any Term Loans or the consummation of any other transactions
contemplated in any Credit Document, including, without limitation, the
reasonable fees and disbursements of counsel incurred in connection with any
such investigation, litigation or other proceeding (but excluding any such
losses, liabilities, claims, damages or expenses to the extent incurred by
reason of the gross negligence or willful misconduct on the part of the Person
to be indemnified), (ii) any Environmental Claim and (iii) any claims for
Non-Excluded Taxes.

                                      -71-


11.6.    AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing and signed by the Required Lenders and the Credit Parties; provided that
no such amendment, change, waiver, discharge or termination shall without the
written consent of each Lender affected thereby:

         (a) extend the final maturity of any Loan or any portion thereof or
postpone any other date fixed for any payment of principal;

         (b) reduce the rate or extend the time of payment of interest (other
than as a result of waiving the applicability of any post-default increase in
interest rates) thereon or fees hereunder;

         (c) reduce or waive the principal amount of any Loan;

         (d) change the Commitment of a Lender from the amount thereof in
effect, other than pursuant to an assignment permitted under Section 3.14 or
11.3(b) or any reduction of the Commitment by the Borrowers pursuant to Section
2.1(f);

         (e) release either Borrower from its obligations, or all or
substantially all of the Guarantors from their obligations, under the Credit
Documents; provided that the Administrative Agent may release a Guarantor if an
equity interest in a Guarantor is transferred in accordance with Section 8.5 or
equity is issued in accordance with Section 11.20;

         (f) amend, modify or waive any provision of this Section 11.6 or
Section 3.3(b), 3.4(a), 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 5.1, 9.1(a), 11.2,
11.3, 11.5 or 11.10 or any provision of any Credit Document which, by its
express terms, requires the consent, approval, agreement or satisfaction of all
of the Lenders;

         (g) reduce any percentage specified in, or otherwise modify, the
definition of Required Lenders; or

         (h) consent to the assignment or transfer by any Credit Party of any of
its rights and obligations under (or in respect of) the Credit Documents other
than any assignment or transfer by a Guarantor permitted under this Credit
Agreement.

Any amendment, change or waiver of any provision of this Credit Agreement or any
other Credit Document at a time when a Default or Event of Default is in
existence, and that would have the effect of eliminating such Default or Event
of Default, shall not be deemed to be effective for the purpose of determining
whether the conditions precedent set forth in Section 5.1 have been satisfied
unless the Required Lenders shall have consented to such amendment, change or
waiver.

If any amendment, waiver or consent with respect to the Credit Documents has
been delivered in writing to a Lender by the Administrative Agent, and such
amendment, waiver or consent requires only the approval of the Required Lenders
to become effective, then such Lender shall have ten Business Days from the date
of receipt of such amendment, waiver or consent to respond thereto. Failure of a
Lender to timely respond to such amendment, waiver or consent shall be deemed an
approval by such Lender to such amendment, waiver or consent.

                                      -72-


No provision of Section 10 may be amended or modified without the consent of the
Administrative Agent.

Notwithstanding the fact that the consent of all the Lenders is required in
certain circumstances as set forth above, (x) each Lender is entitled to vote as
such Lender sees fit on any reorganization plan that affects the Loans and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy
Code supersedes the unanimous consent provisions set forth herein and (y) the
Required Lenders may consent to allow a Credit Party to use cash collateral in
the context of a bankruptcy or insolvency proceeding.

11.7.    COUNTERPARTS/TELECOPY.

         This Credit Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. Delivery of executed
counterparts by telecopy shall be as effective as an original and shall
constitute a representation that an original will be delivered.

11.8.    HEADINGS.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

11.9.    DEFAULTING LENDER.

         Each Lender understands and agrees that if such Lender is a Defaulting
Lender then notwithstanding the provisions of Section 11.6 it shall not be
entitled to vote on any matter requiring the consent of the Required Lenders or
to object to any matter requiring the consent of all the Lenders; provided,
however, that all other benefits and obligations under the Credit Documents
shall apply to such Defaulting Lender.

11.10. SURVIVAL OF INDEMNIFICATION AND REPRESENTATIONS AND WARRANTIES.

         All indemnities set forth herein and all representations and warranties
made herein shall survive the execution and delivery of this Credit Agreement,
the making of the Loans, and the repayment of the Loans and other Obligations
and the termination of the Commitments hereunder.

11.11. GOVERNING LAW; JURISDICTION.

         (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
Any legal action or proceeding with respect to this Credit Agreement or any
other Credit Document may be brought in the courts of the State of New York in
New York County, or of the United States for the Southern District of New York
and, by execution and delivery of this Credit Agreement, each Credit Party

                                      -73-


hereby irrevocably accepts for itself and in respect of its property, generally
and unconditionally, the jurisdiction of such courts. Each Credit Party further
irrevocably consents to the service of process out of any of the aforementioned
courts in any such action or proceeding by the mailing of copies thereof by
registered or certified mail, postage prepaid, to it at the address for notices
pursuant to Section 11.1, such service to become effective fifteen (15) days
after such mailing. Nothing herein shall affect the right of a Lender to serve
process in any other manner permitted by law or to commence legal proceedings or
to otherwise proceed against a Credit Party in any other jurisdiction. Each
Credit Party agrees that a final judgment in any action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law; provided that nothing in this Section
11.11(a) is intended to impair a Credit Party's right under applicable law to
appeal or seek a stay of any judgment.

         (b) Each Credit Party hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Credit Agreement or any
other Credit Document in the courts referred to in subsection (a) hereof and
hereby further irrevocably waives and agrees not to plead or claim in any such
court that any such action or proceeding brought in any such court has been
brought in an inconvenient forum.

11.12. WAIVER OF JURY TRIAL.

         EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR
THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY.

11.13.   TIME.

         All references to time herein shall be references to Eastern Standard
Time or Eastern Daylight Time, as the case may be, unless specified otherwise.

11.14.   SEVERABILITY.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

11.15.   ENTIRETY.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede
all prior agreements and understandings, oral or written, if any, including any
commitment letters or correspondence relating to the Credit Documents or the
transactions contemplated herein and therein.

                                      -74-


11.16. BINDING EFFECT.

         (a) This Credit Agreement shall become effective at such time as all of
the conditions set forth in Section 5.1 have been satisfied or waived by the
Lenders and it shall have been executed by the Credit Parties and the
Administrative Agent, and the Administrative Agent shall have received copies
hereof (telefaxed or otherwise) which, when taken together, bear the signatures
of each Lender, and thereafter this Credit Agreement shall be binding upon and
inure to the benefit of the Credit Parties, the Administrative Agent and each
Lender and their respective successors and assigns.

         (b) This Credit Agreement shall be a continuing agreement and shall
remain in full force and effect until all Loans, interest, fees and other
Obligations have been paid in full and all Commitments have been terminated.
Upon termination, the Credit Parties shall have no further obligations (other
than the indemnification provisions that survive) under the Credit Documents;
provided that should any payment, in whole or in part, of the Obligations be
rescinded or otherwise required to be restored or returned by the Administrative
Agent or any Lender, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, then the Credit Documents shall automatically be
reinstated and all amounts required to be restored or returned and all costs and
expenses incurred by the Administrative Agent or any Lender in connection
therewith shall be deemed included as part of the Obligations.

11.17. CONFIDENTIALITY.

         Each Lender agrees that it will use its reasonable best efforts to keep
confidential and to cause any representative designated under Section 7.11 to
keep confidential any non-public information from time to time supplied to it
under any Credit Document; provided, however, that nothing herein shall prevent
the disclosure of any such information to (a) the extent a Lender in good faith
believes such disclosure is required by Requirement of Law, (b) counsel for a
Lender or to its accountants and other advisors, (c) bank examiners, auditors or
comparable Persons or any regulatory body having jurisdiction over a Lender, (d)
any Affiliate of a Lender, (e) any other Lender, or any assignee, transferee or
participant, or, subject to an agreement containing provisions substantially the
same as those of this Section, (i) any potential assignee, transferee or
participant, of all or any portion of any Lender's rights under this Credit
Agreement who is notified of the confidential nature of the information or (ii)
any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to the Borrowers and their obligations, (f) any
other Person in connection with any litigation to which any one or more of the
Lenders is a party or (g) any other Person to whom disclosure of such
information a Lender believes is necessary or appropriate in its reasonable
judgment in connection with the exercise of remedies or enforcement of rights
hereunder; and provided further that no Lender shall have any obligation under
this Section 11.17 to the extent any such information becomes available on a
non-confidential basis from a source other than a Credit Party or that any
information becomes publicly available other than by a breach of this Section
11.17.

                                      -75-


11.18.   FURTHER ASSURANCES.

         The Credit Parties agree, upon the request of the Administrative Agent,
to promptly take such actions as are necessary to carry out the intent of this
Credit Agreement and the other Credit Documents.

11.19.   RELEASE OF GUARANTORS.

         If a Guarantor issues equity and as a result thereof such Guarantor is
no longer a Material Subsidiary or no longer qualifies as the owner of
Unencumbered Properties, then, as long as no Default or Event of Default exists
after giving effect to the issuance of such equity and the disqualification as
Unencumbered Properties of all properties owned by such Guarantor, the Lenders
agree to release such Guarantor from its obligations hereunder.

11.20.   USA PATRIOT ACT.

         Each Lender hereby notifies the Borrowers that pursuant to the
requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001)) (the "PATRIOT ACT"), it is required to obtain, verify and
record information that identifies the Borrowers, which information includes the
name and address of the Borrowers and other information that will allow such
Lender to identify the Borrowers in accordance with the Patriot Act.

11.21.   LIMITATION ON LIABILITY.

         Each Credit Party waives any right to assert or make any claim against
any Lender or the Administrative Agent for (or to sue any Lender or the
Administrative Agent upon any claim for) any special, indirect, incidental,
punitive or consequential damages in respect of any breach or wrongful conduct
(whether the claim is based on contract, tort or duty imposed by law) in
connection with, arising out of or in any way related to this Agreement, any
other Credit Document or the transactions contemplated hereby or thereby, or any
act, omission or event in connection therewith.

Subsidiaries solely as a result of such Credit Party (or Subsidiary) being a
partner or member in such joint venture shall be treated as not recourse to such
Credit Party (or Subsidiary) as long as the only assets owned by such Credit
Party (or Subsidiary) are its equity interest in such joint venture and any
contributed capital held to fund such equity interest.

                                   SECTION 2

                                CREDIT FACILITY

2.1.     TERM LOANS.

         (a) Term Loans. Subject to the terms and conditions set forth herein,
each Lender severally agrees, on the Effective Date, to make a term loan
(collectively, the "Term Loans") to the Borrowers, in Dollars, in an amount
equal to such Lender's Term Loan Commitment Percentage of the aggregate amount
of Term Loans requested by the Borrowers to be made on such date; provided that
(i) the aggregate amount of Term Loans made may not exceed the Term Loan
Committed Amount and (ii) the Term Loans shall only be made in a single funding.
By no later than 11:00 a.m. on the Effective Date, and in no event later than
11:00 a.m. on October 21, 2004, the Borrowers shall submit an irrevocable
written Notice of Borrowing in the form of Exhibit 2.1(a) to the Administrative
Agent setting forth (A) the amount requested, (B) the specific use of the
proceeds of the requested Term Loans, (C) a certification that the Borrowers
have complied in all respects with Section 5.1 and (D) the date of borrowing.
The Administrative Agent shall provide copies of such Notice of Borrowing to
each Lender. The Commitments shall permanently terminate upon the making of the
Term Loans.

         (b) Funding of Term Loans. On the Effective Date, each Lender will make
its Term Loan Commitment Percentage of the aggregate amount of Term Loans
requested by the Borrowers available to the Administrative Agent by deposit, in
Dollars and in immediately available funds, at the Administrative Agent's office
at the Agency Services Address or at such other address as the Administrative
Agent may designate in writing. The amount of the Term Loans will then be made
available to the Borrowers by the Administrative Agent by crediting the account
of the Borrowers on the books of such office of the Administrative Agent, to the
extent the amount of such Term Loans are made available to the Administrative
Agent. All Term Loans made on the Effective Date shall be Base Rate Loans.
Thereafter, all or any portion of the Term Loans may be converted into
Eurodollar Loans in accordance with the terms of Section 2.1(d) and the
definition of "Interest Period" set forth in Section 1.1.

                                      -23-


         No Lender shall be responsible for the failure or delay by any other
Lender in its obligation to make a Term Loan hereunder; provided, however, that
the failure of any Lender to fulfill its obligations hereunder shall not relieve
any other Lender of its obligations hereunder. Unless the Administrative Agent
shall have been notified by any Lender prior to the date of the Term Loans that
such Lender does not intend to make available to the Administrative Agent its
portion of the Term Loans to be made on such date, the Administrative Agent may
assume that such Lender has or will make the amount of its Term Loan available
to the Administrative Agent on the Effective Date, and the Administrative Agent
in reliance upon such assumption, may (in its sole discretion but without any
obligation to do so) make available to the Borrowers a corresponding amount. If
such corresponding amount is not in fact made available to the Administrative
Agent, the Administrative Agent shall be able to recover such corresponding
amount from such Lender. If such Lender does not pay such corresponding amount
forthwith upon the Administrative Agent's demand therefor, the Administrative
Agent will promptly notify the Borrowers, and the Borrowers shall immediately
pay such corresponding amount to the Administrative Agent. The Administrative
Agent shall also be entitled to recover from such Lender or the Borrowers, as
the case may be, interest on such corresponding amount in respect of each day
from the date such corresponding amount was made available by the Administrative
Agent to the Borrowers to the date such corresponding amount is recovered by the
Administrative Agent at a per annum rate equal to (i) from the Borrowers at the
Adjusted Base Rate and (ii) from such Lender at the Federal Funds Rate if paid
within two Business Days of the date of drawing and thereafter at a rate equal
to the Base Rate.

         (c) Term Notes. Upon the request of any Lender, the Borrowers shall
provide such Lender with a duly executed Term Note, evidencing the Term Loans
made by such Lender, in an original principal amount equal to such Lender's Term
Loan Commitment Percentage of the aggregate amount of the Term Loans requested
by the Borrowers to be made on such date and substantially in the form of
Exhibit 2.1(c).

         (d) Continuations and Conversions. The Borrowers shall have the option
with respect to all or any part of the Term Loans, on any Business Day, to
continue existing Eurodollar Loans for a subsequent Interest Period, to convert
Base Rate Loans into Eurodollar Loans, or to convert Eurodollar Loans into Base
Rate Loans; provided, however, that (i) each such continuation or conversion
must be requested by the Borrowers pursuant to a written Notice of
Continuation/Conversion, in the form of Exhibit 2.1(d), in compliance with the
terms set forth below, (ii) except as provided in Section 3.11, Eurodollar Loans
may only be continued or converted on the last day of the Interest Period
applicable thereto, (iii) Eurodollar Loans may not be continued nor may Base
Rate Loans be converted into Eurodollar Loans during the existence and
continuation of a Default or Event of Default and (iv) any request to continue a
Eurodollar Loan that fails to comply with the terms hereof or any failure to
request a continuation of a Eurodollar Loan at the end of an Interest Period
shall result in a conversion of such Eurodollar Loan to a Base Rate Loan on the
last day of the applicable Interest Period. Each continuation or conversion must
be requested by the Borrowers no later than 11:00 a.m. (A) one Business Day
prior to the date for a requested conversion of a Eurodollar Loan to a Base Rate
Loan or (B) three Business Days prior to the date for a requested continuation
of a Eurodollar Loan or conversion of a Base Rate Loan to a Eurodollar Loan, in
each case pursuant to a written Notice of Continuation/Conversion submitted to
the Administrative Agent (which shall promptly notify each of the Lenders) which
shall set forth (x) whether the Borrowers wish to continue or convert such Loans
and (y) if the request is to continue a Eurodollar Loan or convert a Loan to a
Eurodollar Loan, the Interest Period applicable thereto.

                                      -24-


         (e) Minimum Amounts/Restrictions on Loans. Each request for a
conversion or continuation of a Term Loan shall be subject to the requirements
that (i) each Eurodollar Loan shall be in a minimum amount of $1,000,000 and in
integral multiples of $100,000 in excess thereof, (ii) each Base Rate Loan shall
be in a minimum amount of $500,000 and (iii) no more than four Eurodollar Loans
shall be outstanding at any one time. For the purposes of this Section 2.1(e),
all Eurodollar Loans with the same Interest Periods beginning on the same date
shall be considered as one Eurodollar Loan, but Eurodollar Loans with different
Interest Periods, even if they begin or end on the same date, shall be
considered as separate Eurodollar Loans.

2.2.     JOINT AND SEVERAL LIABILITY OF THE BORROWERS.

         (a) Each of the Borrowers is accepting joint and several liability
hereunder in consideration of the financial accommodation to be provided by the
Lenders under this Credit Agreement, for the mutual benefit, directly and
indirectly, of each of the Borrowers and in consideration of the undertakings of
each of the Borrowers to accept joint and several liability for the obligations
of each of them.

         (b) Each of the Borrowers jointly and severally hereby irrevocably and
unconditionally accepts, not merely as a surety but also as a co-debtor, joint
and several liability with the other Borrower with respect to the payment and
performance of all of the Obligations arising under this Credit Agreement and
the other Credit Documents, it being the intention of the parties hereto that
all the Obligations shall be the joint and several obligations of each of the
Borrowers without preferences or distinction among them.

         (c) If and to the extent that either of the Borrowers shall fail to
make any payment with respect to any of the Obligations as and when due or to
perform any of the Obligations in accordance with the terms thereof, then in
each such event, the other Borrower will make such payment with respect to, or
perform, such Obligation.

         (d) The obligations of each Borrower under the provisions of this
Section 2.2 constitute full recourse obligations of such Borrower, enforceable
against it to the full extent of its properties and assets.

         (e) Except as otherwise expressly provided herein, to the extent
permitted by law, each Borrower hereby waives notice of acceptance of its joint
and several liability, notice of occurrence of any Default or Event of Default
(except to the extent notice is expressly required to be given pursuant to the
terms of this Credit Agreement), or of any demand for any payment under this
Credit Agreement, notice of any action at any time taken or omitted by the
Administrative Agent or the Lenders under or in respect of any of the
obligations hereunder, any requirement of diligence

                                      -25-


and, generally, all demands, notices and other formalities of every kind in
connection with this Credit Agreement. Each Borrower hereby assents to, and
waives notice of, any extension or postponement of the time for the payment of
any of the Obligations, the acceptance of any partial payment thereon, any
waiver, consent or other action or acquiescence by the Administrative Agent or
the Lenders at any time or times in respect of any default by either Borrower in
the performance or satisfaction of any term, covenant, condition or provision of
this Credit Agreement, any and all other indulgences whatsoever by the
Administrative Agent or the Lenders in respect of any of the obligations
hereunder, and the taking, addition, substitution or release, in whole or in
part, at any time or times, of any security for any of such obligations or the
addition, substitution or release, in whole or in part, of either Borrower.
Without limiting the generality of the foregoing, each Borrower assents to any
other action or delay in acting or any failure to act on the part of the
Administrative Agent or the Lenders, including, without limitation, any failure
strictly or diligently to assert any right or to pursue any remedy or to comply
fully with applicable laws or regulations thereunder which might, but for the
provisions of this Section 2.2, afford grounds for terminating, discharging or
relieving such Borrower, in whole or in part, from any of its obligations under
this Section 2.2, it being the intention of each Borrower that, so long as any
of the Obligations hereunder remain unsatisfied, the obligations of such
Borrower under this Section 2.2 shall not be discharged except by performance
and then only to the extent of such performance. The obligations of each
Borrower under this Section 2.2 shall not be diminished or rendered
unenforceable by any winding up, reorganization, arrangement, liquidation,
reconstruction or similar proceeding with respect to either Borrower or a
Lender. The joint and several liability of the Borrowers hereunder shall
continue in full force and effect notwithstanding any absorption, merger,
amalgamation or any other change whatsoever in the name, membership,
constitution or place of formation of either Borrower or any of the Lenders.

         (f) The provisions of this Section 2.2 are made for the benefit of the
Lenders and their successors and assigns, and may be enforced by them from time
to time against either of the Borrowers as often as occasion therefor may arise
and without requirement on the part of the Lenders first to marshal any of its
claims or to exercise any of its rights against the other Borrower or to exhaust
any remedies available to it against the other Borrower or to resort to any
other source or means of obtaining payment of any of the Obligations hereunder
or to elect any other remedy. The provisions of this Section 2.2 shall remain in
effect until all the Obligations shall have been paid in full or otherwise fully
satisfied. If at any time, any payment, or any part thereof, made in respect of
any of the Obligations is rescinded or must otherwise be restored or returned by
the Lenders upon the insolvency, bankruptcy or reorganization of either of the
Borrowers, or otherwise, the provisions of this Section 2.2 will forthwith be
reinstated and in effect as though such payment had not been made.

         (g) Notwithstanding any provision to the contrary contained herein or
in any of the other Credit Documents, to the extent the obligations of either
Borrower shall be adjudicated to be invalid or unenforceable for any reason
(including, without limitation, because of any applicable state or federal law
relating to fraudulent conveyances or transfers) then the obligations of such
Borrower hereunder shall be limited to the maximum amount that is permissible
under applicable law (whether federal or state and including, without
limitation, the Bankruptcy Code).

                                      -26-


2.3.     APPOINTMENT OF BOP.

         BRT hereby appoints BOP to act as its agent for all purposes under this
Credit Agreement (including, without limitation, with respect to all matters
related to the borrowing and repayment of Loans) and agrees that (i) BOP may
execute such documents on behalf of BRT as BOP deems appropriate in its sole
discretion and BRT shall be obligated by all of the terms of any such document
executed on its behalf, (ii) any notice or communication delivered by the
Administrative Agent or the Lender to BOP shall be deemed delivered to BRT and
(iii) the Administrative Agent or the Lenders may accept, and be permitted to
rely on, any document, instrument or agreement executed by BOP on behalf of BRT.

2.4.     NON-RECOURSE.

         Notwithstanding anything herein to the contrary, no recourse shall be
had against Brandywine Realty Services Partnership or any past, present or
future shareholder, officer, director or trustee of BRT for any obligation of
the Credit Parties under the Credit Documents, or for any claim based thereon or
otherwise in respect thereof; provided, however, that this Section 2.4 shall not
restrict or limit any claim against any such Person arising out of or occurring
with respect to fraud or any intentional misrepresentation or any act or
omission that is willful or wanton or constitutes gross negligence or willful
misconduct.

                                   SECTION 3

                    GENERAL PROVISIONS APPLICABLE TO LOANS

3.1.     INTEREST.

         (a) Interest Rate. All Base Rate Loans shall accrue interest at the
Adjusted Base Rate. All Eurodollar Loans shall accrue interest at the Adjusted
Eurodollar Rate.

         (b) Default Rate of Interest. Upon the occurrence, and during the
continuance, of an Event of Default as set forth in Section 9.1(a), the
principal of and, to the extent permitted by law, interest on the Loans and any
other amounts owing hereunder or under the other Credit Documents (including
without limitation fees and expenses) shall bear interest, payable on demand, at
a per annum rate equal to four percent (4%) plus the rate which would otherwise
be applicable (or if no rate is applicable, then the rate for Base Rate Loans
plus four percent (4%) per annum); provided that unless the Loans have been
accelerated, interest, including the default rate of interest, shall only be due
and payable on the Interest Payment Dates.

         (c) Interest Payments. Interest on Loans shall be due and payable in
arrears on each Interest Payment Date. If an Interest Payment Date falls on a
date which is not a Business Day, such Interest Payment Date shall be deemed to
be the succeeding Business Day, except that in the case of Eurodollar Loans
where the succeeding Business Day falls in the succeeding calendar month, such
Interest Payment Date shall be the preceding Business Day.

                                      -27-


3.2. PLACE AND MANNER OF PAYMENTS.

         All payments of principal, interest, fees, expenses and other amounts
to be made by a Borrower under this Credit Agreement shall be made by such
Borrower unconditionally and without deduction for any counterclaim, defense,
recoupment or setoff and received not later than 2:00 p.m. on the date when due,
in Dollars and in immediately available funds, to the Administrative Agent at
its offices in New York City, New York. Payments received after such time shall
be deemed to have been received on the next Business Day. The Borrowers shall,
at the time they make any payment under this Credit Agreement, specify to the
Administrative Agent, the Loans, fees or other amounts payable by the Borrowers
hereunder to which such payment is to be applied (and in the event that they
fail to specify, or if such application would be inconsistent with the terms
hereof, the Administrative Agent shall, subject to Section 3.7, distribute such
payment to the Lenders in such manner as the Administrative Agent may deem
appropriate). The Administrative Agent will distribute any such payment to the
Lenders on the day received if such payment is received prior to 2:00 p.m.;
otherwise the Administrative Agent will distribute such payment to the Lenders
on the next succeeding Business Day. Whenever any payment hereunder shall be
stated to be due on a day which is not a Business Day, the due date thereof
shall be extended to the next succeeding Business Day (subject to accrual of
interest and fees for the period of such extension), except that in the case of
Eurodollar Loans, if the extension would cause the payment to be made in the
next following calendar month, then such payment shall instead be made on the
next preceding Business Day.

3.3. PAYMENTS.

         (a) Voluntary Prepayments. The Borrowers shall have the right to prepay
Term Loans, in whole or in part from time to time without premium or penalty;
provided, however, that (i) Eurodollar Loans may only be prepaid on three
Business Days' prior written notice to the Administrative Agent and any
prepayment of Eurodollar Loans will be subject to Section 3.13, (ii) (x) in the
case of Eurodollar Loans, each such partial prepayment shall be in the minimum
principal amount of $1,000,000 and integral multiples of $100,000 in excess
thereof, or (y) in the case of Base Rate Loans, each such partial prepayment
shall be in the minimum principal amount of $500,000 and integral multiples of
$100,000 in excess thereof.

         (b) Mandatory Prepayments. In the event one or more Capital Markets
Transactions consisting of the issuance of privately placed, non-144A or 144A
(with no registration rights) debt securities is consummated, 100% of the net
proceeds therefrom shall be applied by the Borrowers to permanently reduce the
Term Loans outstanding.

         (c) Application of Prepayments. All amounts required to be paid
pursuant to Section 3.3(b) shall be applied first to Base Rate Loans and then to
Eurodollar Loans. Amounts prepaid on account of Term Loans may not be
reborrowed. All prepayments hereunder shall be subject to Section 3.13.

                                      -28-


3.4.     FEES.

         (a) Administrative Fees. The Borrowers agree to pay to the
Administrative Agent, for its own account, an annual fee as agreed to between
the Borrowers and the Administrative Agent in the Fee Letter.

3.5.     PAYMENT IN FULL AT MATURITY.

         On the Maturity Date, the entire outstanding principal balance of all
Term Loans, together with accrued but unpaid interest and all other sums owing
with respect thereto, shall be due and payable in cash in full, unless
accelerated sooner pursuant to Section 9.2.

3.6.     COMPUTATIONS OF INTEREST AND FEES.

         (a) Except for Base Rate Loans bearing interest based on the Prime
Rate, which shall be calculated on the basis of a 365 or 366 day year as the
case may be, all computations of interest and fees hereunder shall be made on
the basis of the actual number of days elapsed over a year of 360 days. Interest
shall accrue from and include the date of borrowing (or continuation or
conversion) but exclude the date of payment.

         (b) It is the intent of the Lenders and the Credit Parties to conform
to and contract in strict compliance with applicable usury law from time to time
in effect. All agreements between the Lenders and the Credit Parties are hereby
limited by the provisions of this paragraph which shall override and control all
such agreements, whether now existing or hereafter arising and whether written
or oral. In no way, nor in any event or contingency (including but not limited
to prepayment or acceleration of the maturity of any obligation), shall the
interest taken, reserved, contracted for, charged, or received under this Credit
Agreement, under the Notes or otherwise, exceed the maximum nonusurious amount
permissible under applicable law. If, from any possible construction of any of
the Credit Documents or any other document, interest would otherwise be payable
in excess of the maximum nonusurious amount, any such construction shall be
subject to the provisions of this paragraph and such interest shall be
automatically reduced to the maximum nonusurious amount permitted under
applicable law, without the necessity of execution of any amendment or new
document. If any Lender shall ever receive anything of value which is
characterized as interest on the Loans under applicable law and which would,
apart from this provision, be in excess of the maximum lawful amount, an amount
equal to the amount which would have been excessive interest shall, without
penalty, be applied to the reduction of the principal amount owing on the Loans
and not to the payment of interest, or refunded to the Credit Parties or the
other payor thereof if and to the extent such amount which would have been
excessive exceeds such unpaid principal amount of the Loans. The right to demand
payment of the Loans or any other indebtedness evidenced by any of the Credit
Documents does not include the right to receive any interest which has not
otherwise accrued on the date of such demand, and the Lenders do not intend to
charge or receive any unearned interest in the event of such demand. All
interest paid or agreed to be paid to the Lenders with respect to the Loans
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated, and spread throughout the full stated term (including any renewal or
extension) of the Loans so that the amount of interest on account of such
indebtedness does not exceed the maximum nonusurious amount permitted by
applicable law.

                                      -29-


3.7.     PRO RATA TREATMENT.

         Except to the extent otherwise provided herein:

         (a) Loans. Each Term Loan borrowing, each payment or prepayment of
principal of any Term Loan, each payment of fees (other than administrative fees
payable pursuant to Section 3.4), and each conversion or continuation of any
Term Loan, shall (except as otherwise provided in Section 3.10) be allocated pro
rata among the Lenders in accordance with the respective Term Loan Commitment
Percentages of the Lenders (or, if the Commitments of the Lenders have expired
or been terminated, in accordance with the respective principal amounts of the
outstanding Loans of the Lenders); provided that, if any Lender shall have
failed to pay its applicable pro rata share of any Term Loan, then any amount to
which such Lender would otherwise be entitled pursuant to this Section 3.7 shall
instead be payable to the Administrative Agent until the share of such Loan not
funded by such Lender has been repaid; provided further, that in the event any
amount paid to any Lender pursuant to this Section 3.7 is rescinded or must
otherwise be returned by the Administrative Agent, each Lender shall, upon the
request of the Administrative Agent, repay to the Administrative Agent the
amount so paid to such Lender, with interest for the period commencing on the
date such payment is returned by the Administrative Agent until the date the
Administrative Agent receives such repayment at a rate per annum equal to,
during the period to but excluding the date two Business Days after such
request, the Federal Funds Rate, and thereafter, at the Base Rate plus two
percent (2%) per annum.

         (b) Sharing of Payments. The Lenders agree among themselves that,
except to the extent otherwise provided herein, in the event that any Lender
shall obtain payment in respect of any Loan or any other obligation owing to
such Lender under this Credit Agreement through the exercise of a right of
setoff, banker's lien or counterclaim, or pursuant to a secured claim under
Section 506 of the Bankruptcy Code or other security or interest arising from,
or in lieu of, such secured claim, received by such Lender under any applicable
bankruptcy, insolvency or other similar law or otherwise, or by any other means
(other than in connection with an assignment pursuant to Section 3.14 or Section
11.3), in excess of its pro rata share of such payment as provided for in this
Credit Agreement, such Lender shall promptly pay in cash or purchase from the
other Lenders a participation in such Loans and other obligations in such
amounts, and make such other adjustments from time to time, as shall be
equitable to the end that all Lenders share such payment in accordance with
their respective ratable shares as provided for in this Credit Agreement. The
Lenders further agree among themselves that if payment to a Lender obtained by
such Lender through the exercise of a right of setoff, banker's lien,
counterclaim or other event as aforesaid shall be rescinded or must otherwise be
restored, each Lender which shall have shared the benefit of such payment shall,
by payment in cash or a repurchase of a participation theretofore sold, return
its share of that benefit (together with its share of any accrued interest
payable with respect thereto) to each Lender whose payment shall have been
rescinded or otherwise restored. The Credit Parties agree that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including setoff, banker's lien or counterclaim,
with respect to such participation as fully as if such Lender were a holder of
such Loan or other obligation in the amount of such participation. Except as
otherwise expressly provided in this Credit Agreement, if any Lender shall fail
to remit to the Administrative Agent or any other Lender an amount payable by
such Lender to the Administrative Agent or such other Lender pursuant to this
Credit Agreement on the date when such amount is due, such payments shall be
made together with interest thereon for each date from the date such amount is
due until the date such amount is paid to the Administrative Agent or such other
Lender at a rate per annum equal to the Federal Funds Rate. If under any
applicable bankruptcy, insolvency or other similar law, any Lender receives a
secured claim in lieu of a setoff to which this Section 3.7 applies, such Lender
shall, to the extent practicable, exercise its rights in respect of such secured
claim in a manner consistent with the rights of the Lenders under this Section
3.7 to share in the benefits of any recovery on such secured claim.

                                      -30-


3.8.     CAPITAL ADEQUACY.

         If, after the date hereof, any Lender has determined that the adoption
or the becoming effective of, or any change in, or any change by any
Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender, or its parent corporation, with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's (or parent corporation's)
capital or assets as a consequence of its commitments or obligations hereunder
to a level below that which such Lender, or its parent corporation, could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's (or parent corporation's) policies with respect to
capital adequacy), then, upon notice from such Lender to the Borrowers and the
Administrative Agent, the Borrowers shall be obligated to pay to such Lender
such additional amount or amounts as will compensate such Lender (or parent
corporation) on an after-tax basis (after taking into account applicable
deductions and credits in respect of the amount indemnified) for such reduction.
Each determination by any such Lender of amounts owing under this Section shall,
absent manifest error, be conclusive and binding on the parties hereto. This
covenant shall survive the termination of this Credit Agreement and the payment
of the Loans and all other amounts payable hereunder.

3.9.     INABILITY TO DETERMINE INTEREST RATE.

         If prior to the first day of any Interest Period, the Administrative
Agent shall have determined in good faith (which determination shall be
conclusive and binding upon the Borrowers) that, by reason of circumstances
affecting the relevant market, adequate and reasonable means do not exist for
ascertaining the Adjusted Eurodollar Rate or the Eurodollar Rate for such
Interest Period, the Administrative Agent shall give telecopy or telephonic
notice thereof to the Borrowers and the Lenders as soon as practicable
thereafter, and will also give prompt written notice to the Borrowers and the
Lenders when such conditions no longer exist. If such notice is given (a) any
Eurodollar Loans requested to be made on the first day of such Interest Period
shall be made as Base Rate Loans and (b) any Loans that were to have been
converted on the first day of such Interest Period to or continued as Eurodollar
Loans shall be converted to or continued as Base Rate Loans. Until such notice
has been withdrawn by the Administrative Agent, no further Eurodollar Loans
shall be made or continued as such, nor shall the Borrowers have the right to
convert Base Rate Loans to Eurodollar Loans.

                                      -31-


3.10.    ILLEGALITY.

         Notwithstanding any other provision herein, if the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
occurring after the Closing Date shall make it unlawful for any Lender to make
or maintain Eurodollar Loans as contemplated by this Credit Agreement, (a) such
Lender shall promptly give written notice of such circumstances to the Borrowers
and the Administrative Agent (which notice shall be promptly withdrawn whenever
such circumstances no longer exist), (b) the commitment of such Lender hereunder
to make Eurodollar Loans, continue Eurodollar Loans as such and convert a Base
Rate Loan to Eurodollar Loans shall forthwith be cancelled and, until such time
as it shall no longer be unlawful for such Lender to make or maintain Eurodollar
Loans, such Lender shall then have a commitment only to make a Base Rate Loan
when a Eurodollar Loan is requested and (c) such Lender's Loans then outstanding
as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans
on the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law. If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of the
then current Interest Period with respect thereto, the Borrowers shall pay to
such Lender such amounts, if any, as may be required pursuant to Section 3.13;
provided that no such payments shall be required if the conversion of a
Eurodollar Loan occurs within 30 days of the last day of the Interest Period of
such Eurodollar Loan.

3.11.    REQUIREMENTS OF LAW.

         If the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof applicable to any Lender, or compliance by
any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority, in each case made
subsequent to the Closing Date (or, if later, the date on which such Lender
becomes a Lender):

         (a) shall subject such Lender to any tax of any kind whatsoever with
respect to any Eurodollar Loans made by it, or its obligation to make Eurodollar
Loans, or change the basis of taxation of payments to such Lender in respect
thereof (except for Non-Excluded Taxes covered by Section 3.12 (including
Non-Excluded Taxes imposed solely by reason of any failure of such Lender to
comply with its obligations (if any) under Section 3.12(b)) and changes in taxes
measured by or imposed upon the overall net income, or franchise tax (imposed in
lieu of such net income tax), of such Lender or its applicable lending office,
branch, or any Affiliate thereof);

         (b) shall impose, modify or hold applicable any reserve, special
deposit, compulsory loan or similar requirement against assets held by, deposits
or other liabilities in or for the account of, advances, loans or other
extensions of credit by, or any other acquisition of funds by, any office of
such Lender which is not otherwise included in the determination of the Adjusted
Eurodollar Rate hereunder; or

         (c) shall impose on such Lender any other condition (excluding any tax
of any kind whatsoever);

                                      -32-


and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Loans or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, upon notice to the Borrowers from such
Lender, through the Administrative Agent, in accordance herewith, the Borrowers
shall be obligated to promptly pay such Lender, upon its demand, any additional
amounts necessary to compensate such Lender on an after-tax basis (after taking
into account applicable deductions and credits in respect of the amount
indemnified) for such increased cost or reduced amount receivable, provided
that, in any such case, the Borrowers may elect to convert the Eurodollar Loans
made by such Lender hereunder to Base Rate Loans by giving the Administrative
Agent at least one Business Day's notice of such election, in which case the
Borrowers shall promptly pay to such Lender, upon demand, without duplication,
such amounts, if any, as may be required pursuant to Section 3.13. If any Lender
becomes entitled to claim any additional amounts pursuant to this Section 3.11,
it shall provide prompt notice thereof to the Borrowers, through the
Administrative Agent, certifying (x) that one of the events described in this
Section 3.11 has occurred and describing in reasonable detail the nature of such
event, (y) as to the increased cost or reduced amount resulting from such event
and (z) as to the additional amount demanded by such Lender and a reasonably
detailed explanation of the calculation thereof. Such a certificate as to any
additional amounts payable pursuant to this Section 3.11 submitted by such
Lender, through the Administrative Agent, to the Borrowers shall be conclusive
and binding on the parties hereto in the absence of manifest error. This
covenant shall survive the termination of this Credit Agreement and the payment
of the Loans and all other amounts payable hereunder.

3.12.    TAXES.

         (a) Except as provided below in this Section 3.12, all payments made by
the Borrowers under this Credit Agreement and any Notes shall be made free and
clear of, and without deduction or withholding for or on account of, any present
or future income, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, now or hereafter imposed, levied, collected,
withheld or assessed by any court, or governmental body, agency or other
official, excluding taxes measured by or imposed upon the overall net income of
any Lender or its applicable lending office, or any branch or Affiliate thereof,
and all franchise taxes, branch taxes, taxes on doing business or taxes on the
overall capital or net worth of any Lender or its applicable lending office, or
any branch or Affiliate thereof, in each case imposed in lieu of net income
taxes: (i) by the jurisdiction under the laws of which such Lender, applicable
lending office, branch or Affiliate is organized or is located, or in which its
principal executive office is located, or any nation within which such
jurisdiction is located or any political subdivision thereof; or (ii) by reason
of any connection between the jurisdiction imposing such tax and such Lender,
applicable lending office, branch or Affiliate other than a connection arising
solely from such Lender having executed, delivered or performed its obligations,
or received payment under or enforced, this Credit Agreement or any Notes. If
any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions
or withholdings ("Non-Excluded Taxes") are required to be withheld from any
amounts payable to the Administrative Agent or any Lender hereunder or under any
Notes, (a) the amounts so payable to the Administrative Agent or such Lender
shall be increased to the extent necessary to yield to the Administrative Agent
or such Lender (after payment of all Non-Excluded Taxes) interest on any such
other amounts payable hereunder at the rates or in the amounts specified in this
Credit Agreement and any Notes, provided, however, that the Borrowers shall be
entitled to deduct and withhold any Non-Excluded Taxes and shall not be required
to increase any such amounts payable to any Lender that is not organized under
the laws of the United States of America or a state thereof if such Lender fails
to comply with the requirements of paragraph (b) of

                                      -33-


this Section 3.12 whenever any Non-Excluded Taxes are payable by the Borrowers,
and (b) as promptly as possible after request therefor the Borrowers shall send
to the Administrative Agent for its own account or for the account of such
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrowers showing payment thereof. If the Borrowers fail to pay
any Non-Excluded Taxes when due to the appropriate taxing authority or fail to
remit to the Administrative Agent the required receipts or other required
documentary evidence, the Borrowers shall indemnify the Administrative Agent and
any Lender for any incremental taxes, interest or penalties that may become
payable by the Administrative Agent or any Lender as a result of any such
failure. The agreements in this subsection shall survive the termination of this
Credit Agreement and the payment of the Loans and all other amounts payable
hereunder.

         (b) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof shall:

                  (i) (A) on or before the date of any payment by the Borrowers
         under this Credit Agreement or Notes to such Lender, deliver to the
         Borrowers and the Administrative Agent (x) two duly completed copies of
         United States Internal Revenue Service Form W8-BEN or W8-ECI, or
         successor applicable form, as the case may be, certifying that it is
         entitled to receive payments under this Credit Agreement and any Notes
         without deduction or withholding of any United States federal income
         taxes and (y) an Internal Revenue Service Form W-8 or W-9, or successor
         applicable form, as the case may be, certifying that it is entitled to
         an exemption from United States backup withholding tax;

                           (B) deliver to the Borrowers and the Administrative
                  Agent two further copies of any such form or certification on
                  or before the date that any such form or certification expires
                  or becomes obsolete and after the occurrence of any event
                  requiring a change in the most recent form previously
                  delivered by it to the Borrowers; and

                           (C) obtain such extensions of time for filing and
                  complete such forms or certifications as may reasonably be
                  requested by the Borrowers or the Administrative Agent; or

                  (ii) in the case of any such Lender that is not a "bank"
         within the meaning of Section 881(c)(3)(A) of the Internal Revenue
         Code, such Lender shall (a) represent to the Borrowers (for the benefit
         of the Borrowers and the Administrative Agent) that it is not a bank
         within the meaning of Section 881(c)(3)(A) of the Internal Revenue
         Code, (b) furnish to the Borrowers, on or before the date of any
         payment by the Borrowers, with a copy to the Administrative Agent, two
         accurate and complete original signed copies of Internal Revenue
         Service Form W-8, or successor applicable form certifying to such
         Lender's legal entitlement at the date of such certificate to an
         exemption from U.S. withholding tax under the provisions of Section
         881(c) of the Internal Revenue Code with respect to payments to be made
         under this Credit Agreement and any Notes (and to deliver to the
         Borrowers and the Administrative Agent two further copies of such form
         on or before the date it expires or becomes obsolete and after the
         occurrence of any event requiring a change in the most recently
         provided form and, if necessary, obtain any extensions of time
         reasonably requested by the Borrowers or the Administrative Agent for
         filing and completing such forms), and (c) agree, to the extent legally
         entitled to do so, upon reasonable request by the Borrowers, to provide
         to the Borrowers (for the benefit of the Borrowers and the
         Administrative Agent) such other forms as may be reasonably required in
         order to establish the legal entitlement of such Lender to an exemption
         from withholding with respect to payments under this Credit Agreement
         and any Notes.

                                      -34-


         Notwithstanding the above, if any change in treaty, law or regulation
         has occurred after the date such Person becomes a Lender hereunder
         which renders all such forms inapplicable or which would prevent such
         Lender from duly completing and delivering any such form with respect
         to it and such Lender so advises the Borrowers and the Administrative
         Agent then such Lender shall be exempt from such requirements. Each
         Person that shall become a Lender or a participant of a Lender pursuant
         to Section 11.3 shall, upon the effectiveness of the related transfer,
         and if applicable, be required to provide all of the forms,
         certifications and statements required pursuant to this subsection (b);
         provided that in the case of a participant of a Lender, the obligations
         of such participant of a Lender pursuant to this subsection (b) shall
         be determined as if such participant of a Lender were a Lender except
         that such participant of a Lender shall furnish all such required
         forms, certifications and statements to the Lender from which the
         related participation shall have been purchased.

3.13.    COMPENSATION.

         The Borrowers promise to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur as a
consequence of (a) default by the Borrowers in making a borrowing of, conversion
into or continuation of Eurodollar Loans, after the Borrowers have given a
notice requesting the same in accordance with the provisions of this Credit
Agreement, (b) default by the Borrowers in making any prepayment of a Eurodollar
Loan after the Borrowers have given a notice thereof in accordance with the
provisions of this Credit Agreement and (c) any continuation, conversion,
payment or prepayment of Eurodollar Loans on a day which is not the last day of
an Interest Period with respect thereto. Such indemnification shall be
calculated by the Administrative Agent and shall include, without limitation, an
amount equal to (i) the amount of interest which would have accrued on the
amount so prepaid, or not so borrowed, converted or continued, for the period
from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of the applicable Interest Period (or, in the case of a
failure to borrow, convert or continue, the Interest Period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Eurodollar Loans provided for herein minus (ii) the amount of
interest which would have accrued to such Lender on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank
Eurodollar market. The agreements in this Section 3.13 shall survive the
termination of this Credit Agreement and the payment of the Loans and all other
amounts payable hereunder. Notwithstanding the foregoing, any prepayment of a
Eurodollar Loan made hereunder (as a result of a mandatory requirement of this
Credit Agreement) within thirty (30) days of the end of the Interest Period with
respect to such Eurodollar Loan, shall not be subject to this Section 3.13.

                                      -35-


3.14.    MITIGATION; MANDATORY ASSIGNMENT.

         Each Lender shall use reasonable efforts to avoid or mitigate any
increased cost or suspension of the availability of an interest rate under
Sections 3.8 through 3.13 inclusive to the greatest extent practicable
(including transferring the Loans to another lending office or one of its
Affiliates) unless, in the opinion of such Lender, such efforts would be likely
to have an adverse effect upon it. In the event a Lender makes a request to the
Borrowers for additional payments in accordance with Section 3.8, 3.9, 3.10,
3.11, 3.12 or 3.13 or a Lender becomes a Defaulting Lender, then, provided that
no Default or Event of Default has occurred and is continuing at such time, the
Borrowers may, at their own expense (such expense to include any transfer fee
payable to the Administrative Agent under Section 11.3(b) and any expense
pursuant to Section 3.13), and in their sole discretion, require such Lender to
transfer and assign in whole (but not in part), without recourse (in accordance
with and subject to the terms and conditions of Section 11.3(b)), all of its
interests, rights and obligations under this Credit Agreement to an Eligible
Assignee which shall assume such assigned obligations (which Eligible Assignee
may be another Lender, if a Lender accepts such assignment); provided that (a)
such assignment shall not conflict with any law, rule or regulation or order of
any court or other Governmental Authority and (b) the Borrowers or such assignee
shall have paid to the assigning Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the portion of
the Loans hereunder held by such assigning Lender and all other amounts owed to
such assigning Lender hereunder, including amounts owed pursuant to Sections 3.8
through 3.13. Notwithstanding such assignment, and without limiting any other
provision of this Credit Agreement, such assigning Lender shall continue to
benefit from the provisions of Sections 3.8, 3.11, 3.12 and 11.5 with respect to
the period before the effectiveness of such assignment.

                                   SECTION 4

                                   GUARANTY

4.1.     GUARANTY OF PAYMENT.

         Subject to Section 4.7, each of the Guarantors hereby, jointly and
severally, absolutely, irrevocably and unconditionally guarantees to each Lender
the prompt payment of the Obligations in cash in full when due (whether at
stated maturity, as a mandatory prepayment, by acceleration or otherwise). This
Guaranty is a guaranty of payment and not of collection and is a continuing
guaranty and shall apply to all Obligations whenever arising.

4.2.     OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors hereunder are absolute, irrevocable
and unconditional, irrespective of the value, genuineness, validity, regularity
or enforceability of any of the Credit Documents or any other agreement or
instrument referred to therein, to the fullest extent permitted by applicable
law, irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor.
Each Guarantor agrees that this Guaranty may be enforced by the Lenders without
the necessity at any time of resorting to or exhausting any other security or
collateral and without the necessity at any time of having recourse to the Notes
or any other of the Credit Documents or any collateral, if any, hereafter

                                      -36-


securing the Obligations or otherwise and each Guarantor hereby waives the right
to require the Lenders to proceed against the Borrowers or any other Person
(including a co-guarantor) or to require the Lenders to pursue any other remedy
or enforce any other right. Each Guarantor further agrees that it shall have no
right of subrogation, indemnity, reimbursement or contribution against the
Borrowers or any other Guarantor of the Obligations for amounts paid under this
Guaranty until such time as the Lenders have been paid in full, all Commitments
under this Credit Agreement have been terminated and no Person or Governmental
Authority shall have any right to request any return or reimbursement of funds
from the Lenders in connection with monies received under the Credit Documents.
Each Guarantor further agrees that nothing contained herein shall prevent the
Lenders from suing on the Notes or any of the other Credit Documents or
foreclosing any security interest in or Lien on any collateral, if any, securing
the Obligations or from exercising any other rights available to any of them
under this Credit Agreement, the Notes, any of the other Credit Documents, or
any other instrument of security, if any, and the exercise of any of the
aforesaid rights and the completion of any foreclosure proceedings shall not
constitute a discharge of any of any Guarantor's obligations hereunder; it being
the purpose and intent of each Guarantor that its obligations hereunder shall be
absolute, independent, irrevocable and unconditional under any and all
circumstances. Neither any Guarantor's obligations under this Guaranty nor any
remedy for the enforcement thereof shall be impaired, modified, changed or
released in any manner whatsoever by an impairment, modification, change,
release or limitation of the liability of the Borrowers or by reason of the
bankruptcy or insolvency of the Borrowers. Each Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof of reliance of by the Administrative Agent or any Lender
upon this Guaranty or acceptance of this Guaranty. The Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon this Guaranty. All
dealings between the Borrowers and any of the Guarantors, on the one hand, and
the Administrative Agent and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon this
Guaranty. The Guarantors further agree to all rights of set-off as set forth in
Section 11.2.

4.3.     MODIFICATIONS.

         Each Guarantor agrees that (a) all or any part of the security now or
hereafter held for the Obligations, if any, may be exchanged, compromised or
surrendered from time to time; (b) the Lenders shall not have any obligation to
protect, perfect, secure or insure any such security interests, liens or
encumbrances now or hereafter held, if any, for the Obligations or the
properties subject thereto; (c) the time or place of payment of the Obligations
may be changed or extended, in whole or in part, to a time certain or otherwise,
and may be renewed or accelerated, in whole or in part; (d) the Borrowers and
any other party liable for payment under the Credit Documents may be granted
indulgences generally; (e) any of the provisions of the Notes or any of the
other Credit Documents may be modified, amended or waived; (f) any party
(including any co-guarantor) liable for the payment thereof may be granted
indulgences or be released; and (g) any deposit balance for the credit of the
Borrowers or any other party liable for the payment of the Obligations or liable
upon any security therefor may be released, in whole or in part, at, before or
after the stated, extended or accelerated maturity of the Obligations, all
without notice to or further assent by such Guarantor, which shall remain bound
thereon, notwithstanding any such exchange, compromise, surrender, extension,

4.4.     WAIVER OF RIGHTS.

         Each Guarantor expressly waives to the fullest extent permitted by
applicable law: (a) notice of acceptance of this Guaranty by the Lenders and of
all extensions of credit to the Borrowers by the Lenders; (b) presentment and
demand for payment or performance of any of the Obligations; (c) protest and
notice of dishonor or of default (except as specifically required in this Credit
Agreement) with respect to the Obligations or with respect to any security
therefor; (d) notice of the Lenders obtaining, amending, substituting for,
releasing, waiving or modifying any security interest, lien or encumbrance, if
any, hereafter securing the Obligations, or the Lenders' subordinating,
compromising, discharging or releasing such security interests, liens or
encumbrances, if any; (e) all other notices to which such Guarantor might
otherwise be entitled; and (f) the benefit of any laws that exonerate or limit
the liability of guarantors or sureties, and any defenses provided by these
laws.

4.5.     REINSTATEMENT.

         The obligations of the Guarantors under this Guaranty shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Obligations is rescinded or must be
otherwise restored by any holder of any of the Obligations, whether as a result
of any proceedings in bankruptcy or reorganization or otherwise, and each
Guarantor agrees that it will indemnify the Administrative Agent and each Lender
on demand for all reasonable costs and expenses (including, without limitation,
reasonable fees of counsel) incurred by the Administrative Agent or such Lender
in connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment
constituted a preference, fraudulent transfer or similar payment under any
bankruptcy, insolvency or similar law.

4.6.     REMEDIES.

         The Guarantors agree that, as between the Guarantors, on the one hand,
and the Administrative Agent and the Lenders, on the other hand, the Obligations
may be declared to be forthwith due and payable as provided in Section 9 (and
shall be deemed to have become automatically due and payable in the
circumstances provided in Section 9) notwithstanding any stay, injunction or
other prohibition preventing such declaration (or preventing such Obligations
from becoming automatically due and payable) as against any other Person and
that, in the event of such declaration (or such Obligations being deemed to have
become automatically due and payable), such Obligations (whether or not due and
payable by any other Person) shall forthwith become due and payable by the
Guarantors.

4.7.     LIMITATION OF GUARANTY.

         It is the intention and agreement of the Guarantors, the Administrative
Agent and the Lenders that the obligations of each Guarantor hereunder shall be
valid and enforceable against each Guarantor to the maximum extent permitted by
applicable law. Notwithstanding any provision to the contrary contained herein
or in any of the other Credit Documents, to the extent the obligations of any
Guarantor shall be adjudicated or declared to be invalid or unenforceable for
any reason (including, without limitation, because of any applicable state or
federal law relating to fraudulent conveyances or transfers) then the
obligations of such Guarantor hereunder shall be limited to the maximum amount
that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

                                      -38-


4.8.     RIGHTS OF CONTRIBUTION.

         The Credit Parties agree among themselves that, in connection with
payments made hereunder, each Credit Party shall have contribution rights
against the other Credit Parties as permitted under applicable law. Such
contribution rights shall be subordinate and subject in right of payment to the
obligations of the Credit Parties under the Credit Documents and no Credit Party
shall exercise such rights of contribution until all the Obligations have been
paid in full and the Commitments terminated.

                                      -45-


6.15.    COMPLIANCE WITH ERISA.

         Except as would not result in or be reasonably expected to result in a
Material Adverse Effect:

         (a) During the five-year period prior to the date on which this
representation is made or deemed made: (i) no ERISA Event has occurred, and, to
the best of each Credit Party's, each Subsidiary of a Credit Party's and each
ERISA Affiliate's knowledge, no event or condition has occurred or exists as a
result of which any ERISA Event could reasonably be expected to occur, with
respect to any Plan; (ii) no "accumulated funding deficiency," as such term is
defined in Section 302 of ERISA and Section 412 of the Code, whether or not
waived, has occurred with respect to any Plan; (iii) each Plan has been
maintained, operated, and funded in compliance with its own terms and in
material compliance with the provisions of ERISA, the Code, and any other
applicable federal or state laws; and (iv) no Lien in favor or the PBGC or a
Plan has arisen or is reasonably likely to arise on account of any Plan.

         (b) The actuarial present value of all "benefit liabilities" (as
defined in Section 4001(a)(16) of ERISA), whether or not vested, under each
Single Employer Plan, as of the last annual valuation date prior to the date on
which this representation is made or deemed made (determined, in each case, in
accordance with Financial Accounting Standards Board Statement 87, utilizing the
actuarial assumptions used in such Plan's most recent actuarial valuation
report), did not exceed as of such valuation date the fair market value of the
assets of such Plan.

has incurred, or, to the best of each such party's knowledge, is reasonably
expected to incur, any withdrawal liability under ERISA to any Multiemployer
Plan or Multiple Employer Plan. No Credit Party, Subsidiary of a Credit Party or
ERISA Affiliate would become subject to any withdrawal liability under ERISA if
any such party were to withdraw completely from all Multiemployer Plans and
Multiple Employer Plans as of the valuation date most closely preceding the date
on which this representation is made or deemed made. No Credit Party, Subsidiary
of a Credit Party or ERISA Affiliate has received any notification that any
Multiemployer Plan is in reorganization (within the meaning of Section 4241 of
ERISA), is insolvent (within the meaning of Section 4245 of ERISA), or has been
terminated (within the meaning of Title IV of ERISA), and no Multiemployer Plan
is, to the best of each such party's knowledge, reasonably expected to be in
reorganization, insolvent, or terminated.

         (d) No prohibited transaction (within the meaning of Section 406 of
ERISA or Section 4975 of the Code) or breach of fiduciary responsibility has
occurred with respect to a Plan which has subjected or may subject any Credit
Party, any Subsidiary of a Credit Party or any ERISA Affiliate to any liability
under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Code,
or under any agreement or other instrument pursuant to which any Credit Party,
any Subsidiary of a Credit Party or any ERISA Affiliate has agreed or is
required to indemnify any person against any such liability.

                                      -46-


         (e) No Credit Party, Subsidiary of a Credit Party or ERISA Affiliate
has material liability with respect to "expected post-retirement benefit
obligations" within the meaning of the Financial Accounting Standards Board
Statement 106. Each Plan which is a welfare plan (as defined in Section 3(1) of
ERISA) to which Sections 601-609 of ERISA and Section 4980B of the Code apply
has been administered in compliance in all material respects with such sections.

6.16.    ORGANIZATION STRUCTURE/SUBSIDIARIES.

         As of the Closing Date, (a) Schedule 6.16 is a complete and accurate
organization chart of the Combined Parties, and (b) no Credit Party has any
Subsidiaries or owns an interest, directly or indirectly, in any joint venture,
except as set forth on Schedule 6.16. The outstanding equity interest of all
Subsidiaries of the Credit Parties are validly issued, fully paid and
non-assessable and are owned by the Credit Parties free and clear of all Liens.

         Upon the occurrence of an Event of Default, and at any time thereafter

immediately become due and payable without the giving of any notice or other
action by the Administrative Agent or the Lenders, which notice or other action
is expressly waived by the Credit Parties.

Notwithstanding the fact that enforcement powers reside primarily with the

separate right of payment and shall be considered a separate "creditor" holding
a separate "claim" within the meaning of Section 101(5) of the Bankruptcy Code
or any other insolvency statute.

9.3.     ALLOCATION OF PAYMENTS AFTER EVENT OF DEFAULT.

         Notwithstanding any other provisions of this Credit Agreement, after

amounts outstanding under any of the Credit Documents shall be paid over or
delivered as follows:

         the Lenders under the Credit Documents;

                  SECOND, to payment of any fees owed to the Administrative

         fees) of each of the Lenders in connection with enforcing its rights
         under the Credit Documents;

                  FOURTH, to the payment of all accrued fees and interest
         payable to the Lenders hereunder;

                  FIFTH, to the payment of the outstanding principal amount of
         the Loans, pro rata, as set forth below;

                  SIXTH, to all other Obligations which shall have become due
         and payable under the Credit Documents and not repaid pursuant to
         clauses "FIRST" through "FIFTH" above; and

                  SEVENTH, to the payment of the surplus, if any, to whoever may
         be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category and (b) each of the Lenders shall receive an amount equal to
its pro rata share (based on the proportion that the then outstanding Loans held
by such Lender bears to the aggregate then outstanding Loans) of amounts
available to be applied pursuant to clauses "THIRD", "FOURTH," "FIFTH," and
"SIXTH" above.

genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without

Administrative Agent may deem and treat each Lender as the owner of its
interests hereunder for all purposes unless a written notice of assignment,
negotiation or transfer thereof shall have been filed with the Administrative
Agent in accordance with Section 11.3(b). The Administrative Agent shall be
fully justified in failing or refusing to take any action under this Credit

receive such advice or concurrence of the Required Lenders (or, to the extent
provided in Section 11.6, all of the Lenders) as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense (other than any liability or expense resulting from
the gross negligence or willful misconduct of the Administrative Agent) which
may be incurred by it by reason of taking or continuing to take any such action.
The Agent-Related Persons shall in all cases be fully protected in acting, or in
refraining from acting, hereunder or under any of the other Credit Documents in
accordance with a request of the Required Lenders (or to the extent specifically
provided in Section 11.6, all the Lenders) and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders
(including their successors and assigns).

10.5.    NOTICE OF DEFAULT.

         The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Administrative Agent has received notice from a Lender or a Credit Party
referring to the applicable Credit Document, describing such Default or Event of
Default and stating that such notice is a "notice of default." In the event that
the Administrative Agent receives such a notice, or otherwise becomes aware of a
Default or Event of Default, the Administrative Agent shall give prompt notice
thereof to the Lenders. The Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by
the Required Lenders (or, to the extent provided in Section 11.6, all of the
Lenders).

                                      -65-


10.6.    NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Lender expressly acknowledges that no Agent-Related Person has
made any representations or warranties to it and that no act by any
Agent-Related Person hereafter taken, including any review of the affairs of any
Credit Party, shall be deemed to constitute any representation or warranty by
any Agent-Related Person or any other Lender. Each Lender represents to the
Administrative Agent and the Arranger that it has, independently and without
reliance upon any Agent-Related Person or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own appraisal
of and investigation into the business, assets, operations, property, financial
and other conditions, prospects and creditworthiness of the Credit Parties and
made its own decision to make its Loans hereunder and enter into this Credit
Agreement. Each Lender also represents that it will, independently and without
reliance upon any Agent-Related Person or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Credit Agreement, and to make such investigation as it deems
necessary to inform itself as to the business, assets, operations, property,
financial and other conditions, prospects and creditworthiness of the Credit
Parties. Except for notices, reports and other documents expressly required to
be furnished to the Lenders by the Administrative Agent hereunder, no
Agent-Related Person shall have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations,
assets, property, financial or other conditions, prospects or creditworthiness
of the Credit Parties which may come into the possession of any Agent-Related
Person.

10.7.    INDEMNIFICATION.

         The Lenders agree to indemnify each Agent-Related Person (to the extent
not reimbursed by the Credit Parties and without limiting the obligation of the
Credit Parties to do so), ratably according to their respective Commitments (or
if the Commitments have expired or been terminated, in accordance with the
respective principal amounts of outstanding Loans of the Lenders), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including without limitation at any time
following payment in full of the Obligations) be imposed on, incurred by or
asserted against such Agent-Related Person in any way relating to or arising out
of this Credit Agreement or the other Credit Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by such
Agent-Related Person under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the gross negligence or willful
misconduct of such Agent-Related Person. If any indemnity furnished to the
Administrative Agent for any purpose shall, in the opinion of the Administrative
Agent, be insufficient or become impaired, the Administrative Agent may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity (except against its gross negligence or
willful misconduct) is furnished. The agreements in this Section 10.7 shall
survive the payment of the Obligations and all other amounts payable hereunder
and under the other Credit Documents.

                                      -66-


10.8.    ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.

         The Person serving as the Administrative Agent and its Affiliates may
make loans to, accept deposits from and generally engage in any kind of business
with the Credit Parties as though the Person serving as the Administrative Agent
were not the Administrative Agent hereunder. With respect to the Loans made, the
Person serving as the Administrative Agent shall have the same rights and powers
under this Credit Agreement as any Lender and may exercise the same as though it
were not the Administrative Agent, and the terms "Lender" and "Lenders" shall
include the Person serving as the Administrative Agent in its individual
capacity.

10.9.    SUCCESSOR AGENT.

         The Administrative Agent (a) may, at any time, resign upon twenty (20)
days written notice to the Lenders or (b) may be removed, with the consent of
the Borrowers, for willful misconduct or gross negligence by written notice from
the Required Lenders; provided that no consent of the Borrowers shall be
required during the existence and continuation of an Event of Default. Upon any
such resignation or removal, the Required Lenders shall have the right to
appoint a successor Administrative Agent. In the case of the Administrative
Agent's resignation or removal, if no successor Administrative Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within forty-five (45) days after the notice of resignation or
removal, then the retiring Administrative Agent shall select a successor
Administrative Agent provided such successor is a Lender hereunder or an
Eligible Assignee. If no such successor shall have been appointed by the
Administrative Agent, and shall have accepted such appointment, within
forty-five (45) days after such notice of resignation, such notice shall
nevertheless become effective and the Lenders shall perform all of the duties of
the Administrative Agent hereunder until such time, if any, as the Required
Lenders appoint a successor as provided above. Upon the acceptance of any
appointment as the Administrative Agent hereunder by a successor, if any, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring or removed
Administrative Agent, and the retiring or removed Administrative Agent shall be
discharged from its duties and obligations as the Administrative Agent, as
appropriate, under this Credit Agreement and the other Credit Documents and the
provisions of this Section 10.9 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was the Administrative Agent under
this Credit Agreement.

         JPMorgan Chase Bank, as syndication agent hereunder, may resign at any
time without any requirement that a successor syndication agent be appointed in
its stead.

                                      -67-


                                   SECTION 11

                                 MISCELLANEOUS

11.1.    NOTICES.

         Except as otherwise expressly provided herein, all notices and other
communications shall have been duly given and shall be effective (a) when
delivered, (b) when transmitted via telecopy (or other facsimile device), (c)
the Business Day following the day on which the same has been delivered prepaid
or on an invoice arrangement to a reputable national overnight air courier
service, or (d) the third Business Day following the day on which the same is
sent by certified or registered mail, postage prepaid, in each case to the
respective parties at the address or telecopy numbers set forth on Schedule
11.1, or at such other address or numbers as such party may specify by written
notice to the other parties hereto.

11.2.    RIGHT OF SET-OFF.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default and the commencement of remedies described in
Section 9.2, each Lender is authorized at any time and from time to time,
without presentment, demand, protest or other notice of any kind (all of which
rights being hereby expressly waived), to set off and to appropriate and apply
any and all deposits (general or special) and any other indebtedness at any time
held or owing by such Lender (including, without limitation, branches, agencies
or Affiliates of such Lender wherever located) to or for the credit or the
account of any Credit Party against obligations and liabilities of such Credit
Party to the Lenders hereunder, under the Notes, the other Credit Documents or
otherwise, irrespective of whether the Administrative Agent or the Lenders shall
have made any demand hereunder and although such obligations, liabilities or
claims, or any of them, may be contingent or unmatured, and any such set-off
shall be deemed to have been made immediately upon the occurrence of an Event of
Default even though such charge is made or entered on the books of such Lender
subsequent thereto. The Credit Parties hereby agree that any Person purchasing a
participation in the Loans and Commitments hereunder pursuant to Section 11.3(c)
or 3.7(b) may exercise all rights of set-off with respect to its participation
interest as fully as if such Person were a Lender hereunder.

11.3.             BENEFIT OF AGREEMENT.

         (a) Generally. This Credit Agreement shall be binding upon and inure to
the benefit of and be enforceable by the respective successors and assigns of
the parties hereto; provided that none of the Credit Parties may assign and
transfer any of its interests (except as permitted by Section 8.4 or 8.5)
without the prior written consent of the Lenders (and any attempt at such
assignment or transfer without such consent shall be null and void); and
provided further that the rights of each Lender to transfer, assign or grant
participations in its rights and/or obligations hereunder shall be limited as
set forth in subsections (b) and (c) of this Section 11.3. Notwithstanding the
above (including anything set forth in subsections (b) and (c) of this Section
11.3), nothing herein shall restrict, prevent or prohibit the Administrative
Agent or any of its Affiliates from granting any assignment or participation in
any Loan under the terms of

                                      -68-


Section 11.3 hereof; provided, that the consent of the Administrative Agent and
the Borrowers shall not be required for the grant of such assignment or
participation, or shall restrict, prevent or prohibit any Lender from (A)
pledging or assigning a security interest in its rights hereunder or under its
Notes, if any, to secure obligations of such Lender, including any pledge or
assignment to a Federal Reserve Bank in support of borrowings made by such
Lender from such Federal Reserve Bank; provided that no such pledge or
assignment shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto, or
(B) granting assignments or participations (x) in such Lender's funded Loans
under the terms of Section 11.3 hereof; provided, that the consent of the
Administrative Agent and the Borrowers shall not be required for the grant of
such assignment or participation, (y) in such Lender's Loans and/or Commitments
hereunder to its parent company and/or to any other Affiliate of such Lender or
(z) to any existing Lender or Affiliate thereof.

         (b) Assignments. In addition to the assignments permitted by Section
11.3(a), each Lender may, with the prior written consent of the Borrowers and
the Administrative Agent (provided that no consent of the Borrowers shall be
required during the existence and continuation of an Event of Default), which
consent shall not be unreasonably withheld or delayed, assign all or a portion
of its rights and obligations hereunder pursuant to an assignment agreement
substantially in the form of Exhibit 11.3(b) to one or more Eligible Assignees;
provided that (i) any such assignment shall be in a minimum aggregate amount of
$1,000,000 of the Commitments (or the remaining amount of Commitments held by
such Lender) unless otherwise agreed by the Borrowers and Administrative Agent
to reduce such minimum amount and (ii) each such assignment shall be of a
constant, not varying, percentage of all of the assigning Lender's rights and
obligations under the Commitment being assigned. Any assignment hereunder shall
be effective upon satisfaction of the conditions set forth above and delivery to
the Administrative Agent of a duly executed assignment agreement. Upon the
effectiveness of any such assignment, the assignee shall become a "Lender" for
all purposes of this Credit Agreement and the other Credit Documents and, to the
extent of such assignment, the assigning Lender shall be relieved of its
obligations hereunder to the extent of the Loans and Commitment components being
assigned. The Borrowers agree that upon notice of any assignment to an assignee
that was not theretofore a Lender, they will promptly provide to such assignee a
new Note. Each Lender agrees that, in the event it assigns all of its Commitment
hereunder, it shall promptly return the Note or Note(s) executed by the
Borrowers in its favor.

         By executing and delivering an assignment agreement in accordance with
this Section 11.3(b), the assigning Lender thereunder and the assignee
thereunder shall be deemed to confirm to and agree with each other and the other
parties hereto as follows: (i) such assigning Lender warrants that it is the
legal and beneficial owner of the interest being assigned thereby free and clear
of any adverse claim and the assignee warrants that it is an Eligible Assignee;
(ii) except as set forth in clause (i) above, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Credit Agreement, any of the other Credit Documents or any other instrument or
document furnished pursuant hereto or thereto, or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Credit
Agreement, any of the other Credit Documents or any other instrument or document
furnished pursuant hereto or thereto or the financial condition of any Credit
Party or the performance or observance by any Credit Party of any of its
obligations under this Credit Agreement, any of the other Credit Documents or


                                      -69-



any other instrument or document furnished pursuant hereto or thereto; (iii)
such assigning Lender and such assignee each represents and warrants that it is
legally authorized to enter into such assignment agreement; (iv) such assignee
confirms that it has received a copy of this Credit Agreement, the other Credit
Documents and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such assignment
agreement; (v) such assignee will independently and without reliance upon the
Administrative Agent, such assigning Lender or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Credit Agreement and the other Credit Documents; (vi) such assignee
appoints and authorizes the Administrative Agent to take such action on its
behalf and to exercise such powers under this Credit Agreement or any other
Credit Document as are delegated to the Administrative Agent by the terms hereof
or thereof, together with such powers as are reasonably incidental thereto; and
(vii) such assignee agrees that it will perform in accordance with their terms
all the obligations which by the terms of this Credit Agreement and the other
Credit Documents are required to be performed by it as a Lender.

         (c) Participations. In addition to the participations permitted by
Section 11.3(a), each Lender may, without the consent of, or notice to, the
Borrowers or the Administrative Agent, sell, transfer or grant participations in
all or any part of such Lender's interests and obligations hereunder; provided
that (i) such selling Lender shall remain a "Lender" for all purposes under this
Credit Agreement (such selling Lender's obligations under the Credit Documents
remaining unchanged) and the participant shall not constitute a Lender
hereunder, (ii) no such participant shall have, or be granted, rights to approve
any amendment or waiver relating to this Credit Agreement or the other Credit
Documents except to the extent any such amendment or waiver would (A) reduce the
principal of or rate of interest on or fees in respect of any Loans in which the
participant is participating or increase any Commitments with respect thereto,
or (b) postpone the date fixed for any payment of principal (including the
extension of the final maturity of any Loan or the date of any mandatory
prepayment), interest or fees in which the participant is participating, (iii)
sub-participations by the participant (except to an Affiliate of the
participant) shall be prohibited and (iv) any such participations shall be in a
minimum aggregate amount of $1,000,000 of the Commitments and in integral
multiples of $100,000 in excess thereof. In the case of any such participation,
the participant shall not have any rights under this Credit Agreement or the
other Credit Documents (the participant's rights against the selling Lender in
respect of such participation to be those set forth in the participation
agreement with such Lender creating such participation) and all amounts payable
by the Credit Parties hereunder shall be determined as if such Lender had not
sold such participation; provided, however, that such participant shall be
entitled to receive additional amounts under Sections 3.8, 3.11, 3.12 and 3.13
to the same extent that the Lender from which such participant acquired its
participation would be entitled to the benefit of such cost protection
provisions.

         (d) The Administrative Agent shall maintain at the Administrative
Agent's office at the Agency Services Address a copy of each assignment
agreement delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Commitments of, and principal amount of the
Loans owing to, each Lender pursuant to the terms hereof from time to time (the
"REGISTER"). The entries in the Register shall be conclusive absent manifest
error, and the Borrowers, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof


                                      -70-



as a Lender hereunder for all purposes of this Credit Agreement, notwithstanding
notice to the contrary. The Register shall be available for inspection by the
Borrowers and any Lender, at any reasonable time and from time to time upon
reasonable prior notice.

11.4. NO WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Administrative Agent or any
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between the Credit Parties and the
Administrative Agent or any Lender shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, power or privilege hereunder or
under any other Credit Document preclude any other or further exercise thereof
or the exercise of any other right, power or privilege hereunder or thereunder.
The rights and remedies provided herein are cumulative and not exclusive of any
rights or remedies which the Administrative Agent or any Lender would otherwise
have. No notice to or demand on any Credit Party in any case shall entitle any
Credit Party to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Administrative Agent
or the Lenders to any other or further action in any circumstances without
notice or demand.

11.5.    PAYMENT OF EXPENSES; INDEMNIFICATION.

         The Credit Parties agree to: (a) pay all reasonable out-of-pocket costs
and expenses of (i) each Agent-Related Person in connection with (A) the
negotiation, preparation, execution and delivery, syndication and administration
of this Credit Agreement and the other Credit Documents and the documents and
instruments referred to therein (including, without limitation, the reasonable
fees and expenses of Paul, Hastings, Janofsky & Walker LLP, counsel to the
Administrative Agent) and (B) any amendment, waiver or consent relating hereto
and thereto including, but not limited to, any such amendments, waivers or
consents resulting from or related to any work-out, renegotiation or restructure
relating to the performance by the Credit Parties under this Credit Agreement,
and (ii) the Agent-Related Persons and the Lenders in connection with (A)
enforcement of the Credit Documents and the documents and instruments referred
to herein and therein, including, without limitation, in connection with any
such enforcement, the reasonable fees and disbursements of counsel for the
Agent-Related Persons and each of the Lenders, and (B) any bankruptcy or
insolvency proceeding of a Credit Party or any of its Subsidiaries, and (b)
indemnify the Agent-Related Persons, each Lender and its officers, directors,
employees, representatives, Affiliates and agents from and hold each of them
harmless against any and all losses, liabilities, claims, damages or expenses
incurred by any of them as a result of, or arising out of, or in any way related
to, or by reason of, any investigation, litigation or other proceeding (whether
or not any Agent-Related Person or any Lender is a party thereto) related to (i)
the entering into and/or performance of any Credit Document or the use of
proceeds of any Term Loans or the consummation of any other transactions
contemplated in any Credit Document, including, without limitation, the
reasonable fees and disbursements of counsel incurred in connection with any
such investigation, litigation or other proceeding (but excluding any such
losses, liabilities, claims, damages or expenses to the extent incurred by
reason of the gross negligence or willful misconduct on the part of the Person
to be indemnified), (ii) any Environmental Claim and (iii) any claims for
Non-Excluded Taxes.



                                      -71-



11.6.    AMENDMENTS, WAIVERS AND CONSENTS.

         Neither this Credit Agreement nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing and signed by the Required Lenders and the Credit Parties; provided that
no such amendment, change, waiver, discharge or termination shall without the
written consent of each Lender affected thereby:

         (a) extend the final maturity of any Loan or any portion thereof or
postpone any other date fixed for any payment of principal;

         (b) reduce the rate or extend the time of payment of interest (other
than as a result of waiving the applicability of any post-default increase in
interest rates) thereon or fees hereunder;

         (c) reduce or waive the principal amount of any Loan;

         (d) change the Commitment of a Lender from the amount thereof in
effect, other than pursuant to an assignment permitted under Section 3.14 or
11.3(b) or any reduction of the Commitment by the Borrowers pursuant to Section
2.1(f);

         (e) release either Borrower from its obligations, or all or
substantially all of the Guarantors from their obligations, under the Credit
Documents, or release any of the Contributors from their obligations under the
Contributor Guaranty; provided that the Administrative Agent may release a
Guarantor if an equity interest in a Guarantor is transferred in accordance with
Section 8.5 or equity is issued in accordance with Section 11.20;

         (f) amend, modify or waive any provision of this Section 11.6 or
Section 3.3(b), 3.4(a), 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 5.1, 9.1(a), 11.2,
11.3, 11.5 or 11.10 or any provision of any Credit Document which, by its
express terms, requires the consent, approval, agreement or satisfaction of all
of the Lenders;

         (g) reduce any percentage specified in, or otherwise modify, the
definition of Required Lenders; or

         (h) consent to the assignment or transfer by any Credit Party of any of
its rights and obligations under (or in respect of) the Credit Documents other
than any assignment or transfer by a Guarantor permitted under this Credit
Agreement.

Any amendment, change or waiver of any provision of this Credit Agreement or any
other Credit Document at a time when a Default or Event of Default is in
existence, and that would have the effect of eliminating such Default or Event
of Default, shall not be deemed to be effective for the purpose of determining
whether the conditions precedent set forth in Section 5.1 have been satisfied
unless the Required Lenders shall have consented to such amendment, change or
waiver.

If any amendment, waiver or consent with respect to the Credit Documents has
been delivered in writing to a Lender by the Administrative Agent, and such
amendment, waiver or consent requires only the approval of the Required Lenders
to become effective, then such Lender shall have ten Business Days from the date
of receipt of such amendment, waiver or consent to respond thereto. Failure of a


                                      -72-



Lender to timely respond to such amendment, waiver or consent shall be deemed an
approval by such Lender to such amendment, waiver or consent.

No provision of Section 10 may be amended or modified without the consent of the
Administrative Agent.

Notwithstanding the fact that the consent of all the Lenders is required in
certain circumstances as set forth above, (x) each Lender is entitled to vote as
such Lender sees fit on any reorganization plan that affects the Loans and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy
Code supersedes the unanimous consent provisions set forth herein and (y) the
Required Lenders may consent to allow a Credit Party to use cash collateral in
the context of a bankruptcy or insolvency proceeding.

11.7.    COUNTERPARTS/TELECOPY.

         This Credit Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument. Delivery of executed
counterparts by telecopy shall be as effective as an original and shall
constitute a representation that an original will be delivered.

11.8.    HEADINGS.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

11.9.    DEFAULTING LENDER.

         Each Lender understands and agrees that if such Lender is a Defaulting
Lender then notwithstanding the provisions of Section 11.6 it shall not be
entitled to vote on any matter requiring the consent of the Required Lenders or
to object to any matter requiring the consent of all the Lenders; provided,
however, that all other benefits and obligations under the Credit Documents
shall apply to such Defaulting Lender.

11.10.   SURVIVAL OF INDEMNIFICATION AND REPRESENTATIONS AND WARRANTIES.

         All indemnities set forth herein and all representations and warranties
made herein shall survive the execution and delivery of this Credit Agreement,
the making of the Loans, and the repayment of the Loans and other Obligations
and the termination of the Commitments hereunder.

11.11.   GOVERNING LAW; JURISDICTION.

         (a) THIS CREDIT AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
Any legal action or proceeding with respect to this Credit Agreement or any
other Credit Document may be brought in the courts of the State of New York in
New York County, or of the United States for the Southern District of New York
and, by execution and delivery of this Credit Agreement, each Credit Party


                                      -73-



hereby irrevocably accepts for itself and in respect of its property, generally
and unconditionally, the jurisdiction of such courts. Each Credit Party further
irrevocably consents to the service of process out of any of the aforementioned
courts in any such action or proceeding by the mailing of copies thereof by
registered or certified mail, postage prepaid, to it at the address for notices
pursuant to Section 11.1, such service to become effective fifteen (15) days
after such mailing. Nothing herein shall affect the right of a Lender to serve
process in any other manner permitted by law or to commence legal proceedings or
to otherwise proceed against a Credit Party in any other jurisdiction. Each
Credit Party agrees that a final judgment in any action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law; provided that nothing in this Section
11.11(a) is intended to impair a Credit Party's right under applicable law to
appeal or seek a stay of any judgment.

         (b) Each Credit Party hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Credit Agreement or any
other Credit Document in the courts referred to in subsection (a) hereof and
hereby further irrevocably waives and agrees not to plead or claim in any such
court that any such action or proceeding brought in any such court has been
brought in an inconvenient forum.

11.12. WAIVER OF JURY TRIAL.

         EACH OF THE PARTIES TO THIS CREDIT AGREEMENT HEREBY IRREVOCABLY WAIVES
ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT
OF OR RELATING TO THIS CREDIT AGREEMENT, ANY OF THE OTHER CREDIT DOCUMENTS OR
THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY.

11.13.   TIME.

         All references to time herein shall be references to Eastern Standard
Time or Eastern Daylight Time, as the case may be, unless specified otherwise.

11.14.   SEVERABILITY.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

11.15.   ENTIRETY.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede
all prior agreements and understandings, oral or written, if any, including any
commitment letters or correspondence relating to the Credit Documents or the
transactions contemplated herein and therein.


                                      -74-



11.16. BINDING EFFECT.

         (a) This Credit Agreement shall become effective at such time as all of
the conditions set forth in Section 5.1 have been satisfied or waived by the
Lenders and it shall have been executed by the Credit Parties and the
Administrative Agent, and the Administrative Agent shall have received copies
hereof (telefaxed or otherwise) which, when taken together, bear the signatures
of each Lender, and thereafter this Credit Agreement shall be binding upon and
inure to the benefit of the Credit Parties, the Administrative Agent and each
Lender and their respective successors and assigns.

         (b) This Credit Agreement shall be a continuing agreement and shall
remain in full force and effect until all Loans, interest, fees and other
Obligations have been paid in full and all Commitments have been terminated.
Upon termination, the Credit Parties shall have no further obligations (other
than the indemnification provisions that survive) under the Credit Documents;
provided that should any payment, in whole or in part, of the Obligations be
rescinded or otherwise required to be restored or returned by the Administrative
Agent or any Lender, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, then the Credit Documents shall automatically be
reinstated and all amounts required to be restored or returned and all costs and
expenses incurred by the Administrative Agent or any Lender in connection
therewith shall be deemed included as part of the Obligations.

11.17. CONFIDENTIALITY.

         Each Lender agrees that it will use its reasonable best efforts to keep
confidential and to cause any representative designated under Section 7.11 to
keep confidential any non-public information from time to time supplied to it
under any Credit Document; provided, however, that nothing herein shall prevent
the disclosure of any such information to (a) the extent a Lender in good faith
believes such disclosure is required by Requirement of Law, (b) counsel for a
Lender or to its accountants and other advisors, (c) bank examiners, auditors or
comparable Persons or any regulatory body having jurisdiction over a Lender, (d)
any Affiliate of a Lender, (e) any other Lender, or any assignee, transferee or
participant, or, subject to an agreement containing provisions substantially the
same as those of this Section, (i) any potential assignee, transferee or
participant, of all or any portion of any Lender's rights under this Credit
Agreement who is notified of the confidential nature of the information or (ii)
any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to the Borrowers and their obligations, (f) any
other Person in connection with any litigation to which any one or more of the
Lenders is a party or (g) any other Person to whom disclosure of such
information a Lender believes is necessary or appropriate in its reasonable
judgment in connection with the exercise of remedies or enforcement of rights
hereunder; and provided further that no Lender shall have any obligation under
this Section 11.17 to the extent any such information becomes available on a
non-confidential basis from a source other than a Credit Party or that any
information becomes publicly available other than by a breach of this Section
11.17.


                                      -75-



11.18.   FURTHER ASSURANCES.

         The Credit Parties agree, upon the request of the Administrative Agent,
to promptly take such actions as are necessary to carry out the intent of this
Credit Agreement and the other Credit Documents.

11.19.   RELEASE OF GUARANTORS.

         If a Guarantor issues equity and as a result thereof such Guarantor is
no longer a Material Subsidiary or no longer qualifies as the owner of
Unencumbered Properties, then, as long as no Default or Event of Default exists
after giving effect to the issuance of such equity and the disqualification as
Unencumbered Properties of all properties owned by such Guarantor, the Lenders
agree to release such Guarantor from its obligations hereunder.

11.20.   USA PATRIOT ACT.

         Each Lender hereby notifies the Borrowers that pursuant to the
requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001)) (the "PATRIOT ACT"), it is required to obtain, verify and
record information that identifies the Borrowers, which information includes the
name and address of the Borrowers and other information that will allow such
Lender to identify the Borrowers in accordance with the Patriot Act.

11.21.   LIMITATION ON LIABILITY.

         Each Credit Party waives any right to assert or make any claim against
any Lender or the Administrative Agent for (or to sue any Lender or the
Administrative Agent upon any claim for) any special, indirect, incidental,
punitive or consequential damages in respect of any breach or wrongful conduct
(whether the claim is based on contract, tort or duty imposed by law) in
connection with, arising out of or in any way related to this Agreement, any
other Credit Document or the transactions contemplated hereby or thereby, or any
act, omission or event in connection therewith.

declared effective by the Commission or (ii) if after it has become effective,
such registration is interfered with by any stop order, injunction or other
order or requirement of the Commission or other governmental agency or court for
any reason and has not thereafter become effective.

                           2.1.6    Limitations on Registration on Demand.

                                    (i) In no event shall the Trust be required
to effect more than three registrations pursuant to this Section 2.1.

                                    (ii) Notwithstanding anything herein, if the
Trust reasonably believes that the filing of a registration statement with the
Commission would adversely affect the contemplated activities of the Trust, then
the Trust may postpone the filing of the applicable registration statement for a
period not in excess of 60 days or, in the event the filing is being postponed
in connection with a proposed underwritten public offering of the Trust's
securities, for such longer period (not to exceed an additional 30 days) as may
be reasonably requested by the managing underwriter for such proposed offering.

                                    (iii) Notwithstanding anything herein, if
the filing of a registration statement pursuant to this Agreement would require
the Trust to include in a filing with the Commission financial statements of
probable or completed acquisitions in order that such registration statement be
in compliance with rules and regulations of the Commission, then the Trust may
delay the filing of such registration statement until it has included the
requisite financial statements (including any necessary pro forma financial
information) in a filing with the Commission.

                  2.2      Registration Procedures.

                           2.2.1    In connection with the  registration of any
Registrable Securities under the Securities Act as provided in Section 2.1, the
Trust shall as promptly as reasonably practicable:

                                    (i) prepare and file with the Commission the
requisite registration statement to effect such registration and thereafter use
commercially reasonable efforts to cause such registration statement to become
and remain effective;

                                    (ii) use commercially reasonable efforts to
prepare and file with the Commission such amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be
necessary to keep such registration statement effective and to comply with
provisions of the Securities Act with respect to the disposition of all
Registrable Securities covered by such registration statement until all of such
Registrable Securities have been sold thereunder;

                                    (iii) furnish to the Investor such number of
conformed copies of such registration statement and of each such amendment and
supplement thereto (in each case including all exhibits), such number of copies
of the prospectus contained in such registration statement (including each
preliminary prospectus and any summary prospectus) and any other prospectus
filed under Rule 424 under the Securities Act, in conformity with the
requirements of the Securities Act, and such number of copies of such other
documents as the Investor may reasonably request;

                                    (iv) use commercially reasonable efforts (x)
to register or qualify all Registrable Securities under such other securities or
Blue Sky laws of such States of the United States of America where an exemption
is not available and as the Investor shall reasonably request, (y) to keep such
registration or qualification in effect for so long as such registration
statement remains in effect, and (z) to take any other action which may




reasonably be necessary or advisable to enable the Investor to consummate the
disposition in such jurisdictions of the Registrable Securities to be sold by
the Investor, except that the Trust shall not for any such purpose be required
to qualify generally to do business as a foreign trust in any jurisdiction
wherein it would not, but for the requirements of this paragraph (iv), be
obligated to be so qualified or to consent to general service of process in any
such jurisdiction;

                                    (v) notify the Investor upon discovery that,
or upon the happening of any event as a result of which, the prospectus included
in the registration statement filed pursuant to this agreement, as then in
effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, in the light of the circumstances under which they were
made, and promptly prepare and furnish to the Investor such number of copies of
a supplement to or an amendment of such prospectus as may be necessary so that,
as thereafter delivered to the purchasers of such securities, such prospectus
shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances under which they were
made;

                                    (vi) use commercially reasonable efforts to
list all Registrable Securities covered by such registration statement on any
national securities exchange or over-the-counter market, if any, on which
Registrable Securities covered by such registration statement are then listed.

         The Investor agrees that upon receipt of any notice from the Trust of
the happening of an event of the kind described in Section 2.2.1(v), the
Investor shall forthwith discontinue its disposition of Registrable Securities
pursuant to the registration statement relating to such Registrable Securities
until the Investor's receipt of the copies of the supplemented or amended
prospectus contemplated by Section 2.2.1(v).

                  2.3      Holdback Agreements; Information Blackout.

                           2.3.1    Holdback  Agreements.  In connection with an
underwritten public offering of securities of the Trust, the Investor agrees
that, if required by the underwriter or underwriters, it will not effect any
public sale or distribution, including any sale pursuant to Rule 144 under the
Securities Act, of any Registrable Securities, during the period commencing 10
days prior to the expected commencement of the offering and ending 45 days after
the closing of such offering.

                           2.3.2    Information  Blackout.  At any time when a
registration statement effected pursuant to this Section 2 relating to
Registrable Securities is effective, upon written notice from the Trust to the
Investor that the Trust has determined in good faith that sale of Registrable
Securities pursuant to the registration statement would require disclosure by
the Trust of non-public material information not otherwise required, in the
judgment of the Trust, to be disclosed under applicable law, the Investor shall
suspend sales of Registrable Securities pursuant to such registration statement
until the earlier of (a) 45 days after the Trust makes such good faith
determination and (b) such time as the Trust notifies the Investor that such
material information has been disclosed to the public or has ceased to be
material or that sales pursuant to such registration statement may otherwise be
resumed.

                  2.4 Preparation; Investor Cooperation. In connection with the
preparation and filing of any registration statement under the Securities Act in
which the Investor is a selling shareholder, the Trust shall give the Investor
not less than 15 days prior written notice of the preparation of such
registration statement and give the Investor and their counsel and accountants
the opportunity to review and comment on, at the Investor's expense, the
registration statement, each prospectus included therein or filed with the
Commission, and each amendment thereof or supplement thereto (provided that the
Investor shall furnish the Trust with comments on any such amendment or
supplement as promptly as the Trust shall reasonably require). The Investor will




furnish to the Trust such information as the Trust may reasonably request in
connection with the registration and related proceedings under this Section 2.

                  2.5      Indemnification.

                           2.5.1    Indemnification  by  the  Trust. In the
event of any registration of any securities of the Trust under the Securities
Act in which the Investor is a selling shareholder, the Trust shall, and hereby
does, indemnify and hold harmless the Investor from and against any losses,
claims, damages or liabilities, insofar as losses, claims, damages, or
liabilities (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon (a) any untrue statement or
alleged untrue statement of any material fact contained in any registration
statement under which such securities were registered under the Securities Act,
any preliminary prospectus, final prospectus, or summary prospectus contained
therein, or any amendment or supplement thereto, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (b) any violation by
the Trust, its trustees, officers, employees or agents of this Agreement or any
law applicable to and in connection with such registration, and the Trust shall
reimburse the Investor for any legal or any other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
liability, action or proceeding described in clauses (a) or (b); provided,
however, that the Trust shall not be liable in any such case to the extent that
any such loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in such
registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity
with information furnished to the Trust by the Investor. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Investor and shall survive the transfer of such securities by the
Investor.

                           2.5.2    Indemnification  by the Investor.  If any
Registrable Securities are included in any registration statement, the Investor
shall indemnify and hold harmless (in the same manner and to the same extent as
set forth in Section 2.5.1 above) the Trust and each trustee, officer and
employee of the Trust and each Person who controls the Trust within the meaning
of the Securities Act, with respect to any statement or alleged statement in or
omission or alleged omission from such registration statement, any preliminary
prospectus, final prospectus or summary prospectus contained therein, or any
amendment or supplement thereto, if such statement or alleged statement or
omission or alleged omission was made in reliance upon and in conformity with
information furnished to the Trust by the Investor.

                           2.5.3    Notice of  Claims,  Etc.  Promptly after
receipt by an indemnified party of notice of the commencement of any action or
proceeding involving a claim referred to in the preceding paragraphs of this
Section 2.5, such indemnified party shall, if a claim in respect thereof is to
be made against an indemnifying party, immediately give written notice to the
latter of the commencement of such action; provided, however, that the failure
of any indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding paragraphs of this
Section 2.5, except to the extent that the indemnifying party is materially
prejudiced by such failure. In case any such action is brought against an
indemnified party, unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may exist
in respect of such claim, the indemnifying party shall be entitled to
participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified to the extent that the indemnifying
parties may agree, with counsel reasonably satisfactory to such indemnified





party, and after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party shall not
be liable to such indemnified party for any legal or other expenses subsequently
incurred by the latter in connection with the defense thereof other than
reasonable out of pocket costs related to the indemnified party's cooperation
with the indemnifying party, unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties arises in respect of such claim after the assumption of the defense
thereof. No indemnifying party shall be liable for any settlement of any action
or proceeding effected without its written consent, which consent shall not be
unreasonably withheld, delayed or conditioned. Consent of the indemnified party
shall be required for the entry of any judgment or to enter into a settlement
only when such judgment or settlement does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such indemnified party of a
release from all liability in respect such claim or litigation.

                           2.5.4    Contribution.  If the indemnification
provided for in this Section 2.5 shall for any reason be held by a court to be
unavailable to an indemnified party under Section 2.5.1 or 2.5.2 hereof in
respect of any loss, claim, damage or liability, or any action in respect
thereof, then, in lieu of the amount paid or payable under Sections 2.5.1 or
2.5.2 hereof, the indemnified party and the indemnifying party under Sections
2.5.1 or 2.5.2 hereof shall contribute to the aggregate losses, claims, damages
and liabilities (including legal or other expenses reasonably incurred in
connection with investigating the same), (i) in such proportion as shall be
appropriate to reflect the relative benefits received by the Trust and the
Investor or (ii) if the allocation provided by clause (i) above is not permitted
by applicable law, in such proportion as is appropriate to reflect the relative
fault of the Trust and the Investor that resulted in such loss, claim, damage or
liability, or action in respect thereof, as well as any other relevant equitable
considerations. No Person guilty of fraudulent misrepresentation (within the
meaning of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation. In addition, no Person
shall be obligated to contribute hereunder any amounts in payment for any
settlement of any action or claim, effected without such Person's written
consent, which consent shall not be unreasonably withheld.

         3. Decisions; Modification; Waivers. All decisions by, and notices
from, the Investor hereunder shall be made by the holders of not less than a
majority of the Registrable Securities outstanding held by the Investor and all
other holders of Registrable Securities shall be bound by any such decision.
This Agreement may be modified or amended only with the written consent the
Trust, the Partnership and the Investor holding not less than a majority of the
Registrable Securities. No party shall be released from its obligations
hereunder without the written consent of the other party. The observance of any
term of this Agreement may be waived (either generally or in a particular
instance and either retroactively or prospectively) by the party entitled to
enforce such term, but any such waiver shall be effective only if in a writing
signed by the party against which such waiver is to be asserted. Except as
otherwise specifically provided herein, no delay on the part of any party hereto
in exercising any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any waiver on the part of any party hereto of any right,
power or privilege hereunder operate as a waiver of any other right, power or
privilege hereunder nor shall any single or partial exercise of any right, power
or privilege hereunder preclude any other or further exercise thereof or the
exercise of any right, power or privilege hereunder.

         4. Entire Agreement. This Agreement represents the entire understanding
and agreement between the parties hereto with respect to the subject matter
hereof and supersedes all other prior and contemporaneous agreements and
understandings, both written and oral, between the parties with respect to the
subject matter hereof.

         5. Severability. If any provision of this Agreement, or the application
of such provision to any party or circumstance, shall be held invalid, the
remainder of this Agreement or the application of such provision to other
parties or circumstances, to the extent permitted by law, shall not be affected
thereby; provided, that the parties shall negotiate in good faith with respect
to an equitable modification of the provision or application thereof held to be
invalid.

permitted to be given under this Agreement shall be in writing and shall be

                                   ARTICLE II
                         RESTRICTIONS ON DISPOSITIONS OF
                              PROTECTED PROPERTIES

         2.1. GENERAL PROHIBITION ON DISPOSITION OF PROTECTED PROPERTIES. The
REIT, the Partnership and the Subsidiary Partnership agree for the benefit of
each Protected Partner (and the Indirect Owners thereof), for the term of the
Tax Protection Period applicable with respect to a Protected Property, not to
directly or indirectly sell, exchange, transfer, or otherwise dispose of such a
Protected Property or any interest therein (without regard to whether such
disposition is voluntary or involuntary) in a transaction that would cause any
of the Protected Partners (or Indirect Owners thereof) to recognize any
Protected Gain.

         Without limiting the foregoing, the term "sale, exchange, transfer or
disposition" by the Partnership shall be deemed to include, and the prohibition
shall extend to:

              (a) any direct or indirect disposition by any direct or indirect
Subsidiary of any Protected Property or any interest therein;

              (b) any direct or indirect disposition by the Partnership or the
Subsidiary Partnership of any Protected Property (or any direct or indirect
interest therein) that is subject to Section 704(c)(1)(B) of the Code and the
Treasury Regulations thereunder; and


                                       4


              (c) any distribution by the Partnership or the Subsidiary
Partnership to a Protected Partner that is subject to Section 737 of the Code
and the Treasury Regulations thereunder;

         Without limiting the foregoing, a disposition shall include any
transfer, voluntary or involuntary, in a foreclosure proceeding, pursuant to a
deed in lieu of foreclosure, or in a bankruptcy proceeding.

         2.2. EXCEPTIONS WHERE NO GAIN RECOGNIZED. Notwithstanding the
restrictions set forth in Section 2.1, the Partnership or any Subsidiary may
dispose of any Protected Property (or an interest therein) if such disposition
qualifies as a like-kind exchange under Section 1031 of the Code, or an
involuntary conversion under Section 1033 of the Code, or other transaction
(including, but not limited to, a contribution of property to any entity that
qualifies for the non-recognition of gain under Section 721 or Section 351 of
the Code, or a merger or consolidation of the Partnership with or into another
entity that qualifies for taxation as a "partnership" for federal income tax
purposes (a "Successor Partnership")) that, as to each of the foregoing, does
not result (in the year of such disposition or in a later year) in the
recognition of any taxable income or gain to any Protected Partner (or Indirect
Owners) with respect to any of the Preferred Units or OP Units. In further
clarification thereof:

              (a) in the case of a Section 1031 like-kind exchange, if such
exchange is with a "related party" within the meaning of Section 1031(f)(3) of
the Code, any direct or indirect disposition by such related party of the
Protected Property or any other transaction prior to the expiration of the two
(2) year period following such exchange that would cause Section 1031(f)(1) to
apply with respect to such Protected Property (including by reason of the
application of Section 1031(f)(4)) shall be considered a violation of Section
2.1 by the Partnership;

              (b) in the event that at the time of the exchange or other
disposition the Protected Property is secured, directly or indirectly, by
indebtedness that is guaranteed by a Partner Guarantor (or for which a Protected
Partner (or Indirect Owner) otherwise has personal liability) and the transferee
is not a Subsidiary of the Partnership that both is more than 50% owned,
directly or indirectly by the Partnership and is and will continue to be under
the legal control of the Partnership (which shall include a partnership or
limited liability company in which the Partnership or a wholly owned subsidiary
of the Partnership is the sole managing general partner or sole managing member,
as applicable), (a) either (I) such indebtedness shall be repaid in full or (II)
the Partnership shall obtain from the lenders with respect to such indebtedness
a full and complete release of liability for each of the Protected Partners (or
Indirect Owners) that has guaranteed, or otherwise has liability for, such
indebtedness, and (b) if such indebtedness is a Guaranteed Debt and the Tax
Protection Period with respect to Article 3 shall not have expired, the
Partnership shall comply with its covenants set forth in Article 3 below with
respect to such Guaranteed Debt and the Partner Guarantors that are considered
to have liability for such Guaranteed Debt (determined under Section 3.4
treating such events as a repayment of the Guaranteed Debt); and

              (c) in the event of a merger or consolidation involving the
Partnership (or any Subsidiary) and a Successor Partnership, the Successor
Partnership shall have agreed in writing for the benefit of the Protected
Partners (and the Indirect Owners thereof) that all of the restrictions
contained in this Agreement shall continue to apply, including but not limited
to, those with respect to each Protected Property.

         2.3. MERGERS. Any merger or consolidation involving the Partnership or
any Subsidiary of the Partnership, whether or not the Partnership or Subsidiary
is the surviving entity in such merger or consolidation, that results in a
Protected Partner (or an Indirect Owner) being required to recognize part or all
of the Protected Gain shall be deemed to be a disposition of the Protected
Property for purposes of Section 2.1 and Article 4 shall fully apply.


                                       5



         2.4. TAX TREATMENT OF THE TRANSACTION AND THE LOGAN TRANSACTION. The
REIT, the Partnership and the Subsidiary Partnership covenant that except to the
extent a contrary position is required as a result of a change in law after the
date hereof, the Transaction and the Logan Transaction will be reported for tax
purposes on all tax returns and submissions, as follows: (i) the contributions
by the Protected Partners pursuant to the Contribution Agreement related to the
Transaction shall be treated for all purposes as a contribution of property to
the Partnership under Section 721 of the Code in which no gain or loss is
recognized by any Protected Partner (or Indirect Owner) for federal income tax
purposes, (ii) none of the TRCALP Cash Consideration, Deferred Payments, or
Alternate Cash Consideration (each as defined in the Contribution Agreement)
distributed to the Protected Partners shall be treated as giving rise to a
transfer of money or other property that would have to be taken into account
under Treasury Regulations Section 1.707-3 as part of a disguised sale, and
(iii) the Logan Transaction shall be treated for all purposes as a contribution
of property to Subsidiary Partnership under Section 721 of the Code in which no
gain or loss is recognized by any Protected Logan Partner. The parties hereto
agree that they shall not take any income tax position inconsistent with
treating the Transaction and the Logan Transaction as resulting in the
non-recognition of gain or loss to all Protected Partners (and Indirect Owners
thereof). The Protected Partners acknowledge that the foregoing is not a
guarantee that such treatment will be respected for income tax purposes and the
Partnership and the Subsidiary Partnership shall have no liability to a
Protected Partner (or Indirect Owner) as a result of the Internal Revenue
Service successfully asserting a contrary position.

                                  ARTICLE III

                ALLOCATION OF LIABILITIES; GUARANTEE OPPORTUNITY
                       AND DEFICIT RESTORATION OBLIGATIONS

         3.1. MINIMUM LIABILITY ALLOCATION. During the Tax Protection Period,
the Partnership will offer to each Protected Partner (or, at the request of an
Indirect Owner thereof, such Indirect Owner) the opportunity (i) to enter into
Qualified Guarantees of Qualified Guarantee Indebtedness (other than Incurred
Indebtedness), in such amount or amounts so as to cause the amount of
partnership liabilities allocated to such Protected Partner for purposes of
Section 752 of the Code to be not less than such Protected Partner's Minimum
Liability Amount and to cause the amount of partnership liabilities with respect
to which such Protected Partner will be considered to be "at risk" for purposes
of Section 465 of the Code to be not less than such Protected Partner's Minimum
Liability Amount, as provided in this Article 3, and (ii) to enter into a
Qualified Guarantee of Qualified Guarantee Indebtedness, meeting the additional
requirements of Sections 3.2(vii) and (viii), incurred by the Partnership
pursuant to Section 2 of the Contribution Agreement ("Incurred Indebtedness") in
order to cause each Protected Partner's share of the Incurred Indebtedness
(within the meaning of Treasury Regulation Section 1.707-5(b)) (such Protected
Partner's "Allocable Share of the Incurred Indebtedness") to equal such
Protected Partner's share of the cash distribution traceable to the Incurred
Indebtedness (within the meaning of Treasury Regulation Section 1.707-5(b)) used
to fund the TRCALP Cash Consideration, Deferred Payments, and/or Alternate Cash
Consideration. In order to minimize the need for Protected Partners to enter
into Qualified Guarantees, the Partnership will use the optional method under
Treasury Regulation Section 1.752-3(a)(3) to allocate Nonrecourse Liabilities
considered secured by a Protected Property to the Protected Partners to the
extent that the "built-in gain" with respect to those properties exceeds the
amount of the Nonrecourse Liabilities considered secured by such Protected
Property allocated to the Protected Partners under Treasury Regulation Section
1.752-3(a)(2).

         3.2. QUALIFIED GUARANTEE INDEBTEDNESS, INCURRED INDEBTEDNESS AND
QUALIFIED GUARANTEE; TREATMENT OF QUALIFIED GUARANTEE INDEBTEDNESS AND INCURRED
INDEBTEDNESS AS GUARANTEED DEBT. In order for an offer by the Partnership of an
opportunity to guarantee indebtedness to satisfy the requirements of this
Article 3, (1) the indebtedness to be guaranteed must also satisfy conditions


                                       6



(i) through (vi) set forth in this Section 3.2 (indebtedness satisfying all such
conditions is referred to as "Qualified Guarantee Indebtedness"); and with
respect to Incurred Indebtedness, the indebtedness must satisfy the additional
conditions or other requirements set forth in (vii) and (viii) of this Section
3.2; (2) the guarantee by the Partner Guarantors must be pursuant to a Guarantee
Agreement substantially in the form attached hereto as Schedule 3.7 that
satisfies the conditions set forth in Sections 3.2(i) and (iii) (a "Qualified
Guarantee"); (3) the amount of debt offered to be guaranteed by the Partner
Guarantor, if pursuant to Section 3.4, must not exceed the portion of the
Guaranteed Amount for which a replacement guarantee is being offered; and (4)
the debt to be guaranteed must be considered indebtedness of the Partnership for
purposes of determining the adjusted tax basis of the interests of partners in
the Partnership in their partnership interests. If, and to the extent that, a
Partner Guarantor elects to guarantee Qualified Guarantee Indebtedness pursuant
to an offer made in accordance with this Article 3 or guarantees Incurred
Indebtedness, such indebtedness thereafter shall be considered a Guaranteed Debt
and subject to all of this Article 3.

         The conditions that must be satisfied at all times with respect to any
Guaranteed Debt or Incurred Indebtedness (but as to Incurred Indebtedness only
with respect to clauses (i), (iii), (iv), (vii) and (viii) below) offered
pursuant to this Article 3 hereof and the guarantees with respect thereto are as
follows:

              (i) each such guarantee shall be a "bottom dollar guarantee" in
that the lender for the Guaranteed Debt is required to pursue all other
collateral and security for the Guaranteed Debt (other than any "bottom dollar
guarantees" permitted pursuant to this clause (i) and/or Section 3.3 below)
prior to seeking to collect on such a guarantee, and the lender shall have
recourse against the guarantee only if, and solely to the extent that, the total
amount recovered by the lender with respect to the Guaranteed Debt after the
lender has exhausted its remedies as set forth above is less than the aggregate
of the Guaranteed Amounts with respect to such Guaranteed Debt (plus the
aggregate amounts of any other guarantees (x) that are in effect with respect to
such Guaranteed Debt at the time the guarantees pursuant to this Article 3 are
entered into, or (y) that are entered into after the date the guarantees
pursuant to this Article 3 are entered into with respect to such Guaranteed Debt
and that comply with Section 3.5 below, but only to the extent that, in either
case, such guarantees are "bottom dollar guarantees" with respect to the
Guaranteed Debt), and the maximum aggregate liability of each Partner Guarantor
for all Guaranteed Debt shall be limited to the amount actually guaranteed by
such Partner Guarantor;

              (ii) the fair market value of the property collateral (not
including any guarantees) against which the lender has recourse pursuant to the
Guaranteed Debt, determined as of the time the guarantee is entered into (an
independent appraisal relied upon by the lender in making the loan will be the
conclusive evidence of such fair market value when the guarantee is being
entered into in connection with the closing of such loan), shall not be less
than 140% of the sum of (x) Guaranteed Debt, plus (y) the aggregate amounts of
any other guarantees that are in effect with respect to such Guaranteed Debt at
the time the guarantees pursuant to this Article 3 are entered into with respect
to such Guaranteed Debt and that comply with Section 3.2(v) below, but only to
the extent that such guarantees are "bottom dollar guarantees" with respect to
the Guaranteed Debt);

              (iii) (A) the executed guarantee must be executed by and delivered
to the lender, (B) the execution of the guarantee by the Partner Guarantors must
be acknowledged by the lender, and (C) the guarantee must be enforceable under
the laws of the state governing the loan and in which the property securing the
loan is located;

              (iv) as to each Partner Guarantor that is executing a guarantee
pursuant to this Agreement, there must be no other person that would be
considered to "bear the economic risk of loss," within the meaning of Treasury


                                       7



Regulation Section 1.752-2, or would be considered to be "at risk" for purposes
of Section 465(b) with respect to that portion of such debt for which such
Partner Guarantor is being made liable for purposes of satisfying the
Partnership's obligations to such Partner Guarantor under this Article 3;

              (v) the aggregate Guaranteed Amounts with respect to the
Guaranteed Debt will not exceed 35% of the amount of the Guaranteed Debt
outstanding at the time the guarantee is executed. Except for guarantees already
in place at the time a guarantee opportunity is presented to the Protected
Partners, at no time can there be guarantees with respect to the Guaranteed Debt
that are provided by other persons that are "pari passu" with or at a lower
level of risk than the guarantees provided by the Protected Partners. If there
are guarantees already in place at the time a guarantee opportunity is presented
to the Protected Partners that are "pari passu" with or at a lower level of risk
than the guarantees provided by the Protected Partners, then the amount of
Guaranteed Debt subject to such existing guarantees shall be added to the
Guaranteed Amount for purposes of calculating the 35% limitation set forth in
this Section 3.2(v); and

              (vi) the obligor with respect to the Guaranteed Debt is the
Partnership or, in the case of Guaranteed Debt other than Incurred Indebtedness,
an entity in which the Partnership owns, directly and indirectly, not less than
51% of the economic interests and which is and will continue to be under the
legal control of the Partnership (which shall include a partnership or limited
liability company in which the Partnership or a wholly-owned subsidiary of the
Partnership is the sole managing general partner or sole managing member, as
applicable).

         The Partnership shall be deemed to satisfy the requirements of Sections
3.2(i), (ii) and (v) if, in lieu of offering a bottom dollar guarantee of
indebtedness secured by specific properties, it offers a bottom dollar guarantee
(or an indemnity of an existing guarantor) of a general unsecured obligation of
the Partnership which is recourse, without limitation, to all of the assets of
the Partnership and is made by a third party institutional lender with financial
covenants that are standard for such a loan. Such a guarantee may be "pari
passu" with or at a higher level of risk than another bottom dollar guarantee of
such indebtedness provided that the aggregate amount of such other guarantee is
less than $65 million.

         The additional conditions that must be satisfied at all times with
respect to Incurred Indebtedness offered pursuant to this Article 3 hereof and
the guarantees with respect thereto are as follows:

              (vii) the amount of the Incurred Indebtedness shall equal the
amount specified by the Protected Partners as TRCALP Cash Consideration,
Deferred Payments and/or Alternate Cash Consideration in connection with Section
2 of the Contribution Agreement so that all of the cash designated as a
"debt-financed distribution" shall qualify as a debt-financed distribution
attributable to the Incurred Indebtedness with respect to each Protected
Partner, no portion of which is taken into account as a "transfer of money" for
purposes of Section 707 and Treasury Regulation Sections 1.707-1 through
1.707-9;

              (viii) notwithstanding Section 3.2 (vi) or 3.4 hereto, the obligor
with respect to the Incurred Indebtedness shall at all times be the Partnership,
such Incurred Indebtedness shall be a recourse obligation of the Partnership
where the Lender has recourse, without limitation, to all of the assets of the
Partnership, the term of the Incurred Indebtedness is not less than forty-eight
(48) months, and such indebtedness is a distinct and separate liability of the
Partnership in an amount equal to the TRCALP Cash Consideration, Deferred
Payment and/or Alternate Cash Consideration made to the Protected Partners and
for which such Protected Partner Partner Guarantors solely bear the economic
risk of loss within the meaning of Treasury Regulation Section 1.752-2.


                                       8



         3.3. COVENANT WITH RESPECT TO GUARANTEED DEBT COLLATERAL. The
Partnership covenants with the Partner Guarantors with respect to the Guaranteed
Debt that (A) it will comply with the requirements set forth in Section 2.2(b)
upon any disposition of any collateral for a Guaranteed Debt, whether during or
following the Tax Protection Period, and (B) it will not at any time, whether
during or following the Tax Protection Period, pledge the collateral with
respect to a Guaranteed Debt to secure any other indebtedness (unless such other
indebtedness is, by its terms, subordinate in all respects to the Guaranteed
Debt for which such collateral is security) or otherwise voluntarily dispose of
or reduce the amount of such collateral unless either (i) after giving effect
thereto the conditions in Section 3.2 would continue to be satisfied with
respect to the Guaranteed Debt and the Guaranteed Debt otherwise would continue
to be Qualified Guarantee Indebtedness, or in the case of Guaranteed Debt other
than Incurred Indebtedness (ii) the Partnership (A) obtains from the lender with
respect to the original Guaranteed Debt a full and complete release of any
Partner Guarantor unless the Partner Guarantor expressly requests that it not be
released, and (B) if the Tax Protection Period has not expired, offers to each
Partner Guarantor with respect to such original Guaranteed Debt, not less than
30 days prior to such pledge or disposition, the opportunity to enter into a
Qualified Guarantee of other Partnership indebtedness that constitutes Qualified
Guarantee Indebtedness (with such replacement indebtedness thereafter being
considered a Guaranteed Debt and subject to this Article 3) in an amount equal
to the amount of such original Guaranteed Debt that was guaranteed by such
Partner Guarantor.

         3.4. REPAYMENT OR REFINANCING OF GUARANTEED DEBT. The Partnership shall
not, at any time during the Tax Protection Period applicable to a Partner
Guarantor, repay or refinance all or any portion of any Guaranteed Debt unless
(i) after taking into account such repayment, each Partner Guarantor would be
entitled, pursuant to Treasury Regulation Section 1.752-2 (and not Treasury
Regulation Section 1.752-3), to include in its adjusted tax basis for its
Preferred Units or OP Units an amount of Guaranteed Debt equal to its Minimum
Liability Amount plus its Allocable Share of Incurred Indebtedness, or (ii)
alternatively, the Partnership, not less than 30 days prior to such repayment or
refinancing, offers to the applicable Partner Guarantors the opportunity to
enter into a Qualified Guarantee with respect to other Qualified Guarantee
Indebtedness in an amount sufficient so that, taking into account such
guarantees of such other Qualified Guarantee Indebtedness each Partner Guarantor
who guarantees such other Qualified Guarantee Indebtedness in the amount
specified by the Partnership would be entitled, pursuant to Treasury Regulation
Section 1.752-2 (and not Treasury Regulation Section 1.752-3), to include in its
adjusted tax basis for its OP Units or Preferred Units debt equal to the Minimum
Liability Amount plus its Allocable Share of Incurred Indebtedness for such
Partner Guarantor. Notwithstanding the foregoing, under no circumstances shall
the Partnership prepay or refinance prior to the expiration of its term a
Guaranteed Debt which is an Incurred Indebtedness unless the Partnership
simultaneously incurs a new Incurred Indebtedness in the exact same amount,
which is a distinct and separate liability of the Partnership and allows each of
the Protected Partners the opportunity to make a Qualified Guarantee of such
indebtedness in an amount equal to its Allocable Share of the Incurred
Indebtedness (provided that the term of such "refinanced" Incurred Indebtedness
may be forty-eight (48) months less the number of full months that has run on
the term of the prior Incurred Indebtedness which such new Incurred Indebtedness
is refinancing). If an Incurred Indebtedness is at the end of the (48) month
period refinanced with Qualified Guarantee Indebtedness which is not Incurred
Indebtedness, then such Allocable Share of Incurred Indebtedness shall be
considered a Minimum Liability Amount and Schedule 3.1 shall be amended
accordingly.

         3.5. LIMITATION ON ADDITIONAL GUARANTEES WITH RESPECT TO DEBT SECURED
BY COLLATERAL FOR GUARANTEED DEBT. The Partnership shall not offer the
opportunity or make available to any person or entity other than a Protected
Partner a guarantee of any Guaranteed Debt or other debt that is secured,
directly or indirectly, by any collateral for Guaranteed Debt unless such
Guaranteed Debt is not Incurred Indebtedness and (i) such debt by its terms is
subordinate in all respects to the Guaranteed Debt or, if such other guarantees


                                       9



are of the Guaranteed Debt itself, such guarantees by their terms must be paid
in full before the lender can have recourse to the Partner Guarantors (i.e., the
first dollar amount of recovery by the applicable lenders must be applied to the
Guaranteed Amount); provided that the foregoing shall not apply with respect to
additional guarantees of Guaranteed Debt so long as the conditions set forth in
Sections 3.2(ii) and (v) would be satisfied immediately after the implementation
of such additional guarantee (determined in the case of Section 3.2(ii), based
upon the fair market value of the collateral for such Guaranteed Debt at the
time the additional guarantee is entered into and adding the amount of such
additional guarantee(s) to the sum of the applicable Guaranteed Amounts plus any
other preexisting "bottom dollar guarantees" previously permitted pursuant to
this Section 3.5 or Sections 3.2(i) and (ii) above, for purposes of making the
computation provided for in Section 3.2(ii)), and (ii) and such other guarantees
do not have the effect of reducing the amount of the Guaranteed Debt that is
includible by any Partner Guarantor in its adjusted tax basis for its Preferred
Units or OP Units pursuant to Treasury Regulation Section 1.752-2.

         3.6. PROCESS. Whenever the Partnership is required under this Article 3
to offer to one or more of the Partner Guarantors an opportunity to guarantee
Qualified Guarantee Indebtedness, the Partnership shall be considered to have
satisfied its obligation if the other conditions in this Article 3 are satisfied
and, not less than thirty (30) days prior to the date that such guarantee would
be required to be executed in order to satisfy this Article 3, the Partnership
sends by first class mail, return receipt requested, to the last known address
of each such Partner Guarantor (as reflected in the records of the Partnership)
the Guarantee Agreement to be executed (which shall be substantially in the form
of Schedule 3.7 hereto, with such changes thereto as are necessary to reflect
the relevant facts) and a brief letter explaining the relevant circumstances
(including, as applicable, that the offer is being made pursuant to this Article
3, the circumstances giving rise to the offer, a brief summary of the terms of
the Qualified Guarantee Indebtedness to be guaranteed, a brief description of
the collateral for the Qualified Guarantee Indebtedness, a statement of the
amount to be guaranteed, the address to which the executed Guarantee Agreement
must be sent and the date by which it must be received, and a statement to the
effect that, if the Protected Partner fails to execute and return such Agreement
within the time period specified, the Partner Guarantor thereafter would lose
its rights under this Article 3 with respect to the amount of debt that the
Partnership is required to offer to be guaranteed and depending upon the Partner
Guarantor's circumstances and other circumstances related to the Partnership,
the Partner Guarantor could be required to recognize taxable gain as a result
thereof, either currently or prior to the expiration of the Tax Protection
Period, that otherwise would have been deferred. If a notice is properly sent in
accordance with this procedure, the Partnership shall have no responsibility as
a result of the failure of a Partner Guarantor either to receive such notice or
to respond thereto within the specified time period.

         3.7. PRESUMPTION AS TO SCHEDULE 3.7. The form of the Guarantee
Agreement attached hereto as Schedule 3.7 shall be conclusively presumed to
satisfy the conditions set forth in Section 3.2(i) and to have caused the
Guaranteed Debt to be considered allocable to the Protected Partner who enters
into such Guarantee Agreement pursuant to Treasury Regulation Sections 1.752-2
and 1.707-5(b) so long as all of the following conditions are met with respect
such Guaranteed Debt:

              (i) there are no other guarantees in effect with respect to such
Guaranteed Debt (other than the guarantees contemporaneously being entered into
by the Partner Guarantors pursuant to this Article 3 or, in the case of Incurred
Indebtedness, that comply with the paragraph following Section 3.2(vi));

              (ii) the collateral securing such Guaranteed Debt is not, and
shall not thereafter become, collateral for any other indebtedness that is
senior to or pari passu with such Guaranteed Debt;


                                       10



              (iii) no additional guarantees with respect to such Guaranteed
Debt will be entered into during the applicable Tax Protection Period pursuant
to the proviso set forth in Section 3.5;

              (iv) the lender with respect to such Guaranteed Debt is not the
Partnership, any Subsidiary or other entity in which the Partnership owns a
direct or indirect interest, the REIT, any other partner in the Partnership, or
any person related to any partner in the Partnership as determined for purposes
of Treasury Regulation Section 1.752-2 or any person that would be considered a
"related party" as determined for purposes of Section 465 of the Code; and

              (v) none of the REIT, nor any other partner in the Partnership,
nor any person related to any partner in the Partnership as determined for
purposes of Treasury Regulation Section 1.752-2 shall have provided, or shall
thereafter provide, collateral for, or otherwise shall have entered into, or
shall thereafter enter into, a relationship that would cause such person to be
considered to bear the risk of loss with respect to such Guaranteed Debt, as
determined for purposes of Treasury Regulation Section 1.752-2 or that would
cause such entity to be considered "at risk" with respect to such Guaranteed
Debt, as determined for purposes of Section 465 of the Code.

                                   ARTICLE IV
                               REMEDIES FOR BREACH

         4.1. MONETARY DAMAGES. In the event that the Partnership or the
Subsidiary Partnership breaches its obligations set forth in Article 2, Article
3, Article 5, Article 6 or Article 7 with respect to a Protected Partner (or
Indirect Owner thereof), the Protected Partner's (and Indirect Owner's) sole
right shall be to receive from the Partnership, and the Partnership shall pay to
such Protected Partner (or Indirect Owner thereof) as damages, an amount equal
to:

              (a) in the case of a violation of Section 2.4 or Articles 3, 5, 6,
or 7, the aggregate federal, state and local income taxes (including any
interest and penalties that are determined to be applicable) incurred by the
Protected Partner (or its Indirect Owners) as a result of the income or gain
allocated to, or otherwise recognized by, such Protected Partner (or its
Indirect Owners) by reason of such breach;

              (b) in the case of a violation of Article 2 (other than Section
2.4), the aggregate federal, state, and local income taxes (including any
interest and penalties that are determined to be applicable) incurred with
respect the Protected Gain incurred with respect to the Protected Property that
is allocable to such Protected Partner (or Indirect Owners thereof) under the
Partnership Agreement;

plus in the case of either (a) or (b), an amount equal to the aggregate federal,
state, and local income taxes payable by the Protected Partner (or Indirect
Owners thereof) (including any interest and penalties that are determined to be
applicable) as a result of the receipt of any payment required under this
Section 4.1 on a fully grossed up basis (i.e., so that the amount remaining to
the Protected Partner (or Indirect Owners) after the payments of any federal,
state and local taxes on all such payments due to the Protected Partners (or
Indirect Owners) is the amount required to be paid to the Protected Partner (or
Indirect Owners) under Section 4.1(a) or (b) before calculation of such
amounts.)

         For purposes of computing the amount of federal, state, and local
income taxes required to be paid by a Protected Partner (or Indirect Owners
thereof), (i) any deduction for state income taxes payable as a result thereof
actually allowed in computing federal income taxes shall be taken into account,
and (ii) a Protected Partner's (or Indirect Owner's) tax liability shall be
computed using the highest federal, state and local marginal income tax rates
that would be applicable to such Protected Partner's (or Indirect Owner's)
taxable income (taking into account the character of such income or gain) for


                                       11



the year with respect to which the taxes must be paid, without regard to any
deductions, losses or credits that may be available to such Protected Partner
(or Indirect Owner) that would reduce or offset its actual taxable income or
actual tax liability if such deductions, losses or credits could be utilized by
the Protected Partner (or Indirect Owner) to offset other income, gain or taxes
of the Protected Partner (or Indirect Owner), either in the current year, in
earlier years, or in later years.

         4.2. PROCESS FOR DETERMINING DAMAGES. If the Partnership or the
Subsidiary Partnership has breached or violated any of the covenants set forth
in Article 2, Article 3, Article 5, Article 6 or Article 7 (or a Protected
Partner (or Indirect Owner thereof)) asserts that the Partnership has breached
or violated any of the covenants set forth in Article 2, Article 3, Article 5,
Article 6, or Article 7), the Partnership and the Protected Partner (or Indirect
Owners thereof) agree to negotiate in good faith to resolve any disagreements
regarding any such breach or violation and the amount of damages, if any,
payable to such Protected Partner (or Indirect Owners thereof) under Section 4.1
(and to the extent applicable, Section 4.4). If any such disagreement cannot be
resolved by the Partnership and such Protected Partner (or Indirect Owner
thereof) within (i) sixty (60) days after the receipt of notice from the
Partnership of such breach and the amount of income to be recognized by reason
thereof, (ii) sixty (60) days after the receipt of a notice from the Protected
Partner (or Indirect Owner) that the Partnership has breached its obligation,
which notice shall set forth the amount of income asserted to be recognized by
the Protected Partner (or Indirect Owner) as a result of the breach, or (iii)
ten (10) days following the receipt of notice from the Internal Revenue Service,
or other taxing authority, asserting that the Protected Partner (or Indirect
Owners) recognized taxable income as a result of a breach of this Agreement or
on account of an actual or constructive cash distribution under Subchapter K of
the Code (or the corresponding provision of state or local law) that exceeded
the Protected Partner's adjusted income tax basis in the Units, the Partnership
and the Protected Partner (or Indirect Owner) shall, in the case of an event
described in clauses (i) and (ii) above, jointly retain a nationally recognized
big four independent public accounting firm (an "Accounting Firm") to act as an
arbitrator to resolve as expeditiously as possible all points of any such
disagreement (including, without limitation, whether a breach of any of the
covenants set forth in Article 2, Article 3, Article 5, Article 6 or Article 7,
has occurred and, if so, the amount of damages to which the Protected Partner
(or Indirect Owners thereof) is entitled as a result thereof, determined as set
forth in Section 4.1 (and to the extent applicable, Section 4.4). All
determinations made by the Accounting Firm with respect to the resolution of any
breach or violation of any of the covenants set forth in Article 2, Article 3,
Article 5, Article 6 or Article 7 and the amount of damages payable to the
Protected Partner (or Indirect Owners) under Section 4.1 (and to the extent
applicable, Section 4.4) shall, subject to a subsequent notice received pursuant
to clause (iii) and the last sentence of this Section 4.2, be final, conclusive
and binding on the Partnership and the Protected Partner (or Indirect Owner);
provided, however, that a Protected Partner (or Indirect Owner) shall be
permitted to make a claim for a breach of this Agreement at any time and without
regard to any determination made by the Accounting Firm. The fees and expenses
of any Accounting Firm incurred in connection with any such determination shall
be shared equally by the Partnership and the Protected Partner (or Indirect
owner), provided that if the amount determined by the Accounting Firm to be owed
by the Partnership to the Protected Partner (or Indirect Owner) is more than
five percent (5%) higher than the amount proposed by the Partnership to be owed
to such Protected Partner (or Indirect Owner) prior to the submission of the
matter to the Accounting Firm, then all of the fees and expenses of any
Accounting Firm incurred in connection with any such determination shall be paid
by the Partnership, and if the amount determined by the Accounting Firm to be
owed by the Partnership to the Protected Partner (or Indirect Owner) is less
than 95% of the amount proposed by the Protected Partner (or Indirect Owner) to
be owed to the Protected Partner (or Indirect Owner) prior to the submission of
the matter to the Accounting Firm then all of the fees and expenses of any
Accounting Firm incurred in connection with any such determination shall be paid
by the Protected Partner (or Indirect Owner). In the case of any event described
in clause (iii) of this Section 4.2, the amount shown as due by the Internal
Revenue Service or other taxing authority shall be presumed to be damages
resulting from a breach of this Agreement and the amount of any such damages
shall be increased by the amount of interest and penalties required to be paid


                                       12



by the Protected Partner (or Indirect Owners thereof) so that the amount of the
damages under this Section 4.1 shall not be less than the amount required to be
paid to the Internal Revenue Service or other taxing authority in respect of the
notice, grossed up for any additional amount required so that the net amount
remaining after the reduction in the proceeds received on account of federal,
state, and local taxes, plus interest and penalties, will be the amount of all
taxes interest and penalties required to be paid by the Protected Partner (or
Indirect Owner).

         4.3. REQUIRED NOTICES; TIME FOR PAYMENT. In the event that there has
been a breach of Article 2, Article 3, Article 5, Article 6, or Article 7 the
Partnership shall provide to the Protected Partners notice of the transaction or
event giving rise to such breach not later than at such time as the Partnership
provides to the Protected Partners the Schedule K-1's to the Partnership's
federal income tax return as required in accordance with Section 7.4 below. All
payments required under this Article 4 to any Protected Partner (or Indirect
Owners) shall be made to such Protected Partner (or Indirect Owners) on or
before April 15 of the year following the year in which the gain recognition
event giving rise to such payment took place; provided, that, if the Protected
Partner (or Indirect Owners) is required to make estimated tax payments that
would include such gain, the Partnership shall make a payment to the Protected
Partner (or Indirect Owners) on or before the due date for such estimated tax
payment and such payment from the Partnership shall be in an amount that
corresponds to the amount of the estimated tax being paid by such Protected
Partner (or Indirect Owners) at such time. In the event of a payment made after
the date required pursuant to this Section 4.3, interest shall accrue on the
aggregate amount required to be paid from such date to the date of actual
payment at a rate equal to the higher of (i) the "prime rate" of interest, as
published in the Wall Street Journal (or if no longer published there, as
announced by Citibank) effective as of the date the payment is required to be
made plus 10% or (ii) twenty percent, but not to exceed the maximum amount
permitted by law.

         4.4. ADDITIONAL DAMAGES FOR BREACHES OF SECTION 2.2(B), SECTION 3.2
AND/OR SECTION 3.3. Notwithstanding any of the foregoing in this Article 4, in
the event that the Partnership or the Subsidiary Partnership should breach any
of its covenants set forth in Section 2.2(b), Section 3.2 and/or Sections 3.3
(i) or (ii) and a Protected Partner (or Indirect Owner) is required to make a
payment in respect of such indebtedness that it would not have had to make if
such breach had not occurred (an "Excess Payment"), then, in addition to the
damages provided for in the other Sections of this Article 4, the Partnership
shall pay to such Protected Partner (or Indirect Owners) an amount equal to the
sum of (i) the Excess Payment plus (ii) the aggregate federal, state and local
income taxes, if any, computed as set forth in Section 4.1, required to be paid
by such Protected Partner (or Indirect Owners) by reason of this Section 4.4
becoming operative (for example, because the breach by the Partnership and this
Section 4.4 caused all or any portion of the indebtedness in question no longer
to be considered debt includible in adjusted tax basis by the affected Protected
Partner pursuant to Treasury Regulation Section 1.752-2(a)), plus (iii) an
amount equal to the aggregate federal, state and local income taxes required to
be paid by the Protected Partner, (or Indirect Owners) computed as set forth in
Section 4.1, as a result of any payment required under this Section 4.4.

                                   ARTICLE V
                      SECTION 704(C) METHOD AND ALLOCATIONS

         5.1. APPLICATION OF "TRADITIONAL METHOD." Notwithstanding any provision
of the Partnership Agreement, the Partnership and the Subsidiary Partnership
shall use the "traditional method" under Regulations Section 1.704-3(b) for
purposes of making all allocations under Section 704(c) of the Code (with a
"curative allocation" to offset the effects of the "ceiling rule," upon any sale
of a Protected Property).



                                       13



                                   ARTICLE VI
               ALLOCATIONS OF LIABILITIES PURSUANT TO REGULATIONS
                                UNDER SECTION 752

         6.1. ALLOCATION METHODS TO BE FOLLOWED. All tax returns prepared by the
Partnership with respect to the Tax Protection Period that allocate liabilities
of the Partnership for purposes of Section 752 and the Treasury Regulations
thereunder shall treat each Partner Guarantor as being allocated for federal
income tax purposes an amount of recourse debt (in addition to any nonrecourse
debt otherwise allocable to such Partner Guarantor in accordance with the
Partnership Agreement and Treasury Regulations Section 1.752-3 and any other
recourse liabilities allocable to such Partner Guarantor by reason of guarantees
of indebtedness entered into pursuant to other agreements with the Partnership)
pursuant to Treasury Regulation Section 1.752-2 equal to the sum of such Partner
Guarantor's Minimum Liability Amount and Allocable Share of Incurred
Indebtedness, as set forth on Schedule 3.1 hereto and as may be reduced pursuant
to the terms of this Agreement, and the Partnership and the REIT shall not,
during or with respect to the Protected Period, take any contrary or
inconsistent position in any federal, state or local income tax returns
(including, without limitation, information returns, such as Schedules K-1,
provided to partners in the Partnership and returns of Subsidiaries of the
Partnership) or any dealings involving the Internal Revenue Service (including,
without limitation, any audit, administrative appeal or any judicial proceeding
involving the income tax returns of the Partnership or the tax treatment of any
holder of partnership interests the Partnership).

         6.2. EXCEPTION TO REQUIRED ALLOCATION METHOD. Notwithstanding the
provisions of this Agreement, the Partnership shall not be required to make
allocations of Guaranteed Debt, Incurred Indebtedness or other recourse debt of
the Partnership to the Protected Partners as set forth in this Agreement if and
to the extent that the Partnership determines in good faith that there may not
be "substantial authority" (within the meaning of Section 6662(d)(2)(B)(i) of
the Code) for such allocation; provided that the Partnership shall provide to
each Protected Partner (or in the event of their death or disability, their
executor, guardian or custodian, as applicable), notice of such determination
and if, within forty-five (45) days after the receipt thereof, the Partnership
is provided an opinion of a law firm recognized as expert in such matters or a
nationally recognized public accounting firm to the effect that there is
"substantial authority" (within the meaning of Section 6662(d)(2)(B)(i) of the
Code) for such allocations, the Partnership shall continue to make allocations
of Guaranteed Debt or other recourse debt of the Partnership to the Protected
Partners as set forth in this Agreement; provided further that if there shall
have been a judicial determination in a proceeding to which the Partnership is a
party and as to which the Protected Partners (or Indirect Owners) have been
allowed to participate as and to the extent contemplated in Article 7 to the
effect that such allocations are not correct, Section 6.1 shall not apply unless
the matter is being appealed to an applicable court of appeals and the opinion
described above from counsel or accountants engaged by a Protected Partner (or
Indirect Owner) shall have been provided, except that such opinion shall be to
the effect that it is more likely than not that such allocations will be
respected. In no event shall this Section 6.2 be construed to relieve the
Partnership from any liability arising from a failure by the Partnership to
comply with one or more of the provisions of Article 3 of this Agreement.

         6.3. COOPERATION IN THE EVENT OF A CHANGE. If a change in the
Partnership's allocations of Guaranteed Debt or other recourse debt of the
Partnership to the Protected Partners is required by reason of circumstances
described in Section 6.2, the Partnership and its professional tax advisors
shall cooperate in good faith with each Protected Partner (or Indirect Owners
thereof) (or in the event of their death or disability, their executor, guardian
or custodian, as applicable) and their professional tax advisors to develop
alternative allocation arrangements and/or other mechanisms that protect the
income tax positions of the Protected Partners (and Indirect Owners) in the


                                       14



manner contemplated by the allocations of Guaranteed Debt or other recourse debt
of the Partnership to the Protected Partners (and Indirect Owners) as set forth
in this Agreement.

                                   ARTICLE VII
                                 TAX PROCEEDINGS

         7.1. NOTICE OF TAX AUDITS. If any claim, demand, assessment (including
a notice of proposed assessment) or other assertion is made with respect to
Taxes against the Protected Partners (or Indirect Owners) or the Partnership the
calculation of which involves a matter covered in this Agreement or the tax
treatment of the Transaction or the Logan Transaction ("Tax Claim") or if the
REIT or the Partnership receives any notice from any jurisdiction with respect
to any current or future audit, examination, investigation or other proceeding
("Proceeding") involving the Protected Partners (or Indirect Owners) or the
Partnership or that otherwise could involve a matter covered in this Agreement
and could directly or indirectly affect the Protected Partners (or Indirect
Owners) (adversely or otherwise), then the REIT or the Partnership, as
applicable, shall promptly notify the Protected Partners of such Tax Claim or
Proceeding.

         7.2. CONTROL OF TAX PROCEEDINGS. The REIT, as the general partner of
the Partnership shall have the right to control the defense, settlement or
compromise of any Proceeding or Tax Claim; provided, however, that the REIT
shall not consent to the entry of any judgment or enter into any settlement with
respect to such Tax Claim or Proceeding without the prior written consent of the
Protected Partners (unless, and only to the extent, that any Taxes required to
be paid by the Protected Partners (or Indirect Owners) as a result thereof would
be required to be reimbursed by the Partnership and the REIT under Article 4 and
the Partnership and the REIT agree in connection with such settlement or
consent, to make such required payments); provided further that the Partnership
shall keep the Protected Partners (and Indirect Owners) duly informed of the
progress thereof to the extent that such Proceeding or Tax Claim could directly
or indirectly affect (adversely or otherwise) the Protected Partners (or
Indirect Owners) and that the Protected Partners (or Indirect owners) shall have
the right to review and comment on any and all submissions made to the to
Internal Revenue Service, a court, or other governmental body with respect to
such Tax Claim or Proceeding and that the Partnership will consider such
comments in good faith. Notwithstanding the foregoing, the Protected Partners
shall have the right, with counsel of their choosing, to jointly control, with
the REIT, any Proceeding or Tax Claim relating to the tax treatment of the
Transaction or the Logan Transaction.

         7.3. TIMING OF TAX RETURNS; PERIODIC TAX INFORMATION. The Partnership
shall cause to be delivered to each Protected Partner, no later than April 15 of
each year (beginning in 2005), an estimate of the Schedules K-1 that the
Partnership or Subsidiary Partnership, as applicable, is required to deliver to
such Protected Partners with respect to the prior taxable year, and a final
Schedule K-1 by July 15. In addition, the Partnership and the Subsidiary
Partnership agree to provide to the Protected Partners, upon request, an
estimate of the taxable income expected to be allocable for a specified taxable
year from the Partnership or Subsidiary Partnership to each Protected Partner
and the entities that they control, provided that such estimates shall not be
required to be provided more frequently than once each calendar quarter.

                                  ARTICLE VIII
           AMENDMENT OF THIS AGREEMENT; WAIVER OF CERTAIN PROVISIONS;
                        APPROVAL OF CERTAIN TRANSACTIONS

         8.1. AMENDMENT. This Agreement may not be amended, directly or
indirectly (including by reason of a merger between the Partnership and another
entity) except by a written instrument signed by both the REIT, as general
partner of the Partnership, and each of the Protected Partners.


                                       15



         8.2. WAIVER. Notwithstanding the foregoing, upon written request by the
Partnership, each Protected Partner (or Indirect Owner), in its sole discretion,
may waive the payment of any damages that is otherwise payable to such Protected
Partner (or Indirect Owner) pursuant to Article 4 hereof. Such a waiver shall be
effective only if obtained in writing from the affected Protected Partner (or
Indirect Owner).

                                   ARTICLE IX
                                  MISCELLANEOUS

         9.1. ADDITIONAL ACTIONS AND DOCUMENTS. Each of the parties hereto
hereby agrees to take or cause to be taken such further actions, to execute,
deliver, and file or cause to be executed, delivered and filed such further
documents, and will obtain such consents, as may be necessary or as may be
reasonably requested in order to fully effectuate the purposes, terms and
conditions of this Agreement.

         9.2. ASSIGNMENT. No party hereto shall assign its or his rights or
obligations under this Agreement, in whole or in part, except by operation of
law, without the prior written consent of the other parties hereto, and any such
assignment contrary to the terms hereof shall be null and void and of no force
and effect.

         9.3. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
shall inure to the benefit of the Protected Partners, the Indirect Owners and
their respective successors and permitted assigns, whether so expressed or not.
This Agreement shall be binding upon the REIT, the Partnership, the Subsidiary
Partnership and any entity that is a direct or indirect successor, whether by
merger, transfer, spin-off or otherwise, to all or substantially all of the
assets of either the REIT or the Partnership (or any prior successor thereto as
set forth in the preceding portion of this sentence), provided that none of the
foregoing shall result in the release of liability of the REIT and the
Partnership hereunder. The REIT, the Partnership, and the Subsidiary Partnership
covenant with and for the benefit of the Protected Partners (and Indirect Owners
thereof) not to undertake any transfer of all or substantially all of the assets
of either entity (whether by merger, transfer, spin-off or otherwise) unless the
transferee has in writing acknowledged and agreed to be bound by this Agreement,
provided that the foregoing shall not be deemed to permit any transaction
otherwise prohibited by this Agreement.

         9.4. TRANSFER OR DEATH. If a Protected Partner (or Indirect Owner)
transfers its direct or indirect interest in Preferred Units, OP Units or
interests in Subsidiary Partnership in a fully taxable transaction or dies while
holding OP Units, Preferred Units or interests in Subsidiary Partnership, and
the transferee of such OP Units, Preferred Units or interests in Subsidiary
Partnership receives a basis step-up in connection with such event such that the
adjusted basis of the interest is equal to the greater of the fair market value
of the interest or the share of the Partnership's or the Subsidiary
Partnership's indebtedness allocable to the interest under Section 752 of the
Code, then such transferee of the OP Units, Preferred Units or interests in
Subsidiary Partnership formerly owned, directly or indirectly, by such Protected
Partner (or Indirect Owner) (the "Affected Interest") will not be eligible to
receive an indemnity payment under Section 4.1, hereof, or to recover damages
for a breach of this Agreement other than pursuant to Section 2.2(b) or Section
3.3 with respect to such Affected Interest with respect to events occurring
subsequent to such death or transfer. The Protected Partners (and Indirect
Owners) agree not to take any action which would intentionally prevent a
transferee of a direct or indirect interest in Preferred Units, OP Units or
interests in Subsidiary Partnership, in a fully taxable transaction or upon
death, from receiving a basis step-up.

         9.5. MODIFICATION; WAIVER. No failure or delay on the part of any party
hereto in exercising any power or right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,


                                       16



preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the parties hereunder are cumulative
and not exclusive of any rights or remedies which they would otherwise have. No
modification or waiver of any provision of this Agreement, nor consent to any
departure by any party therefrom, shall in any event be effective unless the
same shall be in writing, and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given. No notice to
or demand on any party in any case shall entitle such party to any other or
further notice or demand in similar or other circumstances.

         9.6. REPRESENTATIONS AND WARRANTIES REGARDING AUTHORITY;
NONCONTRAVENTION.

                  9.6.1. Representations and Warranties of the REIT and the

general principles of equity. The execution and delivery of this Agreement by
each of the REIT, the Partnership and the Subsidiary Partnership do not, and the
performance by each of its respective obligations hereunder will not, conflict
with, or result in any violation of (i) the Partnership Agreement or (ii) any
other agreement applicable to the REIT, the Partnership and/or the Subsidiary
Partnership, other than, in the case of clause (ii), any such conflicts or
violations that would not materially adversely affect the performance by the
Partnership, the Subsidiary Partnership or the REIT of their obligations
hereunder.

                  9.6.2. Representations and Warranties of the Protected
Partners. Each of the Protected Partners has the requisite power and authority

of the Protected Partners.

         9.7. CAPTIONS. The Article and Section headings contained in this
Agreement are inserted for convenience of reference only, shall not be deemed to
