     which (a) the total amount of interest which would have otherwise accrued
     hereunder on each installment of principal prepaid or not so drawn, during
     the period beginning on the date of such prepayment or failure to draw and
     ending on the last day of the applicable LIBOR Rate Loan Interest Period
     (the "REEMPLOYMENT PERIOD"), exceeds (b) the total amount of interest which
     would accrue, during the Reemployment Period, on any readily marketable

     payment, such bond or other obligation of the United States of America to
     be in an amount equal (as nearly as may be) to the amount of principal so
     paid or not drawn after elected and to have maturity at the end of the
     Reemployment Period, and the interest to accrue thereon to take account of
     amortization of any discount from par or accretion of premium above par at
     which the same is selling at the time of designation. Each such amount is
     hereinafter referred to as an "INSTALLMENT AMOUNT".

<Page>

                                      -17-

          (ii)   Second, each Installment Amount shall be treated as payable on
     the last day of the LIBOR Rate Loan Interest Period which would have been
     applicable had such principal installment not been prepaid or not borrowed.

          (iii)  Third, the amount to be paid on each such breakage date shall
     be the present value of the Installment Amount determined by discounting
     the amount thereof from the date on which such Installment Amount is to be
     treated as payable, at the same yield to maturity as that payable upon the
     bond or other obligation of the United States of America designated as
     aforesaid by the Administrative Agent.

     If by reason of an Event of Default the Administrative Agent elects to
declare a LIBOR Rate Loan to be immediately due and payable, then any breakage
fee with respect to such LIBOR Rate Loan shall become due and payable in the
same manner as though the Borrower had exercised such right of prepayment.

     LIBOR BUSINESS DAY. Any day on which commercial banks are open for
international business (including dealings in Dollar deposits) in London.

Dollars for a period of time comparable to such Interest Period which appears on
the Telerate page 3750 (or such other page as may replace that page on the
Telerate service) as of 11:00 a.m. London time on the date that is two (2) LIBOR
Business Days prior to the beginning of such Interest Period; PROVIDED, HOWEVER,
if the rate described above does not appear on the Telerate System on any
applicable interest determination date, the LIBOR Rate shall be the rate
(rounded upwards as described above, if necessary) for deposits in Dollars for a
period of time substantially equal to the Interest Period which appears on the
Reuters Page "LIBO" (or such other page as may replace the LIBO Page on that
service for the purpose of displaying such rates), as of 11:00 a.m. London time
on the date that is two (2) LIBOR Business Days prior to the beginning of such
Interest Period.

     If both the Telerate and Reuters systems are unavailable, then the rate for
that date will be determined on the basis of the offered rates for deposits in
Dollars for a period of time comparable to the Interest Period which are offered
by four major banks in the London interbank market at approximately 11:00 a.m.
London time on the date that is two (2) LIBOR Business Days prior to the

<Page>

                                      -18-

beginning of such Interest Period. The principal London office of each of the
four major London banks will be requested to provide a quotation of its Dollar
deposit offered rate. If at least two such quotations are provided, the rate for
that date will be the arithmetic mean of the quotations. If fewer than two
quotations are provided as requested, the rate for that date will be determined
on the basis of the rates quoted for loans in Dollars to leading European banks
for a period of time comparable to the Interest Period by major banks in New
York City at approximately 11:00 a.m. New York City time on the date that is two
(2) LIBOR Business Days prior to the beginning of such Interest Period. In the
event that the Administrative Agent is unable to obtain any quotation as
provided above, it will be deemed that the LIBOR Rate cannot be determined.

     In the event that the Board of Governors of the Federal Reserve System
shall impose a reserve requirement with respect to LIBOR deposits of the
Lenders, then for any period during which such reserve requirement shall apply,
the LIBOR Rate shall be equal to the amount determined above divided by an
amount equal to one (1.00) minus the Eurocurrency Reserve Rate.

          (a) REVOLVING CREDIT LOANS. Subject to the provisions of Section 2.5
and the other terms and conditions set forth in this Agreement, each of the
Lenders severally agrees to lend to the Borrower and the Borrower may borrow,
repay, and reborrow from each Lender from time to time from the Closing Date up
to but not including the Maturity Date upon notice by the Borrower to the
Administrative Agent given in accordance with Section 2.5 hereof, such sums as
are requested by the Borrower up to a maximum aggregate principal amount

and warranty by the Borrower that the conditions set forth in Section 10 have

Section 11 have been satisfied on the date of such request and will be satisfied
on the proposed Drawdown Date of the requested Revolving Credit Loan or Swing
Loan, PROVIDED that the making of such representation and warranty by the
Borrower shall not limit the right of any Lender not to lend if such conditions
have not been met. No Revolving Credit Loan or Swing Loan shall be required to

the conditions contained in Section 10 have been satisfied as of the Closing
Date and all of the conditions set forth in Section 11 have been met at the time
of any request for a Revolving Credit Loan or Swing Loan.

          (b) SWING LOANS.

               (i)     BASIC TERMS. During the term of this Agreement, the Swing
     Lender agrees, on the terms and conditions set forth in this Agreement, to
     make certain loans to the Borrower (each, a "SWING LOAN") pursuant to this
     Section 2.1(b)(i) from time to time in amounts

<Page>

                                      -30-

     such that after giving effect to such loan (A) the aggregate principal
     amount of Swing Loans does not at any time exceed the Swing Loan
     Commitment, and (B) the outstanding amount of all Revolving Credit Loans,
     Swing Loans, Competitive Bid Loans and the Maximum Drawing Amount on all
     Letters of Credit outstanding shall not exceed the Total Commitment in
     effect at such time. Each Swing Loan shall be in an aggregate principal
     amount of at least $2,000,000 (except that any Swing Loan may be in the
     aggregate available amount of Swing Loans determined in accordance with the
     immediately preceding sentence). Within the foregoing limits, the Borrower
     may borrow under this Section 2.1(b)(i), repay or, to the extent permitted
     by Section 2.9, prepay Swing Loans and reborrow at any time during the term
     of this Agreement under this Section 2.1(b)(i). Notwithstanding anything to
     the contrary contained herein, the Swing Lender shall not make a Swing Loan
     after the occurrence and during the continuance of an Event of Default. No
     Swing Loan may be outstanding on the last Business Day of any calendar
     month.

               (ii)    CONVERSION OF SWING LOANS TO REVOLVING CREDIT LOANS. The
     Swing Lender may, on behalf of the Borrower (which hereby irrevocably
     directs the Swing Lender to act on its behalf), on notice given by the
     Swing Lender no later than 12:00 noon (New York City time), on the Business
     Day on or immediately following the funding of any Swing Loan, request each
     Lender to make, and each Lender (including the Swing Lender) hereby agrees
     to make, an Alternate Base Rate Loan, in an amount (with respect to each
     Lender, its "SWING LOAN REFUND AMOUNT") equal to such Lender's Commitment
     Percentage of the aggregate principal amount of the Swing Loans (the
     "REFUNDED SWING LOANS") outstanding on the date of such notice, to repay
     the Swing Lender. Unless any of the events described in Sections 12.1(g) or
     (h) with respect to the Borrower shall have occurred and be continuing or
     Revolving Credit Loans cannot otherwise be made on such date (in which case
     the terms of Section 2.1(b)(iii) shall govern), each Lender shall make such
     Alternate Base Rate Loan available to the Administrative Agent at its
     address specified in or pursuant to Section 19(b) in immediately available
     funds, not later than 1:00 P.M. (New York City time), on the Business Day
     immediately following the date of such notice. The Swing Lender shall be
     deemed to have made such Alternate Base Rate Loan in an amount equal to (x)
     the amount of such Swing Loan less (y) the aggregate amount of the Swing
     Loan Refund Amount of all other Lenders. The Administrative Agent shall pay
     the proceeds of such Alternate Base Rate Loans to the Swing Lender, which
     shall

<Page>

                                      -31-

     immediately apply such proceeds to repay Refunded Swing Loans. Effective on
     the day such Alternate Base Rate Loans are made, the portion of the Swing
     Loans so paid (or deemed paid in the case of the Swing Lender) shall no
     longer be outstanding as Swing Loans, shall no longer be due as Swing Loans
     under the Note held by the Swing Lender, and shall be due as Alternate Base
     Rate Loans under the respective Notes issued to the Lenders (including the
     Swing Lender) in accordance with each Lender's Swing Loan Refund Amount.
     The Borrower authorizes the Swing Lender to charge the Borrower's accounts
     with the Administrative Agent (up to the amount available in each such
     account) in order to immediately pay the amount of such Refunded Swing
     Loans to the extent amounts received from the Lenders are not sufficient to
     repay in full such Refunded Swing Loans.

               (iii)   PURCHASE OF PARTICIPATIONS IN SWING LOANS. If, prior to
     the time Revolving Credit Loans would have otherwise been made pursuant to
     Section 2.1(b)(ii), any of the events described in Sections 12.1(g) or (h)
     with respect to the Borrower shall have occurred and be continuing or
     Revolving Credit Loans cannot otherwise be made on such date, each Lender
     shall, on the date such Revolving Credit Loans were to have been made
     pursuant to the notice referred to in Section 2.1(b)(ii) (the "REFUNDING
     DATE"), purchase an undivided participating interest in the Swing Loans in
     an amount equal to such Lender's Swing Loan Refund Amount. On the Refunding
     Date, each Lender shall transfer to the Swing Lender, in immediately
     available funds, such Lender's Swing Loan Refund Amount, and upon receipt
     thereof the Swing Lender shall deliver to such Lender a Swing Loan
     participation certificate dated the date of the Swing Lender's receipt of
     such funds and in the Swing Loan Refund Amount of such Lender.

               (iv)    PAYMENTS ON PARTICIPATED SWING LOANS. Whenever, at any
     time after the Swing Lender has received from any Lender such Lender's
     Swing Loan Refund Amount pursuant to Section 2.1(b)(iii), the Swing Lender
     receives any payment on account of the Swing Loans in which the Lenders
     have purchased participations pursuant to Section 2.1(b)(iii), the Swing
     Lender will promptly distribute to each such Lender its ratable share
     (determined on the basis of the Swing Loan Refund Amounts of all of the
     Lenders) of such payment (appropriately adjusted, in the case of interest
     payments, to reflect the period of time during which such Lender's
     participating interest was outstanding and funded); PROVIDED, HOWEVER, that
     in the event that such payment received by the Swing Lender is required to
     be

<Page>

                                      -32-

     returned, such Lender will return to the Swing Lender any portion thereof
     previously distributed to it by the Swing Lender.

               (v)     OBLIGATIONS TO REFUND OR PURCHASE PARTICIPATIONS IN SWING
     LOANS ABSOLUTE. Each Lender's obligation to transfer the amount of a Swing
     Loan made in accordance with Section 2.1(b)(i) to the Swing Lender as
     provided in Section 2.1(b)(ii) or to purchase a participating interest
     pursuant to Section 2.1(b)(iii) shall be absolute and unconditional and
     shall not be affected by any circumstance, including, without limitation,
     (A) any setoff, counterclaim, recoupment, defense or other right which such
     Lender, the Borrower or any other Person may have against the Swing Lender
     or any other Person, other than the Swing Lender's gross negligence or
     willful misconduct in connection with making any such Swing Loan, (B) the
     occurrence or continuance of a Default or an Event of Default or the
     termination or reduction of the Commitments, (C) any adverse change in the
     condition (financial or otherwise) of the Borrower or any other Person, (D)
     any breach of this Agreement by the Borrower, any other Lender or any other
     Person, or (E) any other circumstance, happening or event whatsoever,
     whether or not similar to any of the foregoing.

     Section 2.2.   INCREASE OF TOTAL COMMITMENT. Unless a Default or an Event
of Default has occurred and is continuing, the Borrower, by written notice to
the Administrative Agent, may request on up to four (4) occasions during the
term of this Agreement that the Total Commitment be increased by an amount not
less than $25,000,000 per request and not more than $200,000,000 in the
aggregate (such that the Total Commitment after such increase shall never exceed
$800,000,000); PROVIDED that for any such request (a) the Borrower shall not
have requested the one-year extension of the Maturity Date pursuant to the
definition thereof, (b) any Lender which is a party to this Agreement prior to
such request for increase, at its sole discretion, may elect to increase its
Commitment but shall not have any obligation to so increase its Commitment, and
(c) in the event that each Lender does not elect to increase its Commitment, the
Arrangers shall use commercially reasonable efforts to locate additional lenders
willing to hold commitments for the requested increase, and the Borrower may
also identify additional lenders willing to hold commitments for the requested
increase, PROVIDED that the Administrative Agent shall have the right to approve
any such additional lender, which approval will not be unreasonably withheld or
delayed. In the event that lenders commit to any such increase, the Total
Commitment and the Commitments of the committed Lenders shall be increased, the
Commitment Percentages of the Lenders shall be adjusted, new Notes shall be
issued, the Borrower shall make such

<Page>

                                      -33-

borrowings and repayments as shall be necessary to effect the reallocation of
the Commitments, and other changes shall be made to the Loan Documents as may be
necessary to reflect the aggregate amount, if any, by which Lenders have agreed
to increase their respective Commitments or make new Commitments in response to
the Borrower's request for an increase in the Total Commitment pursuant to this
Section 2.2, in each case without the consent of the Lenders other than those
Lenders increasing their Commitments. The fees payable by the Borrower upon any
such increase in the Total Commitment shall be agreed upon by the Arrangers and
the Borrower at the time of such increase.

     Notwithstanding the foregoing, nothing in this Section 2.2 shall constitute
or be deemed to constitute an agreement by any Lender to increase its Commitment
hereunder.

     Section 2.3.   THE NOTES. The Revolving Credit Loans shall, and Swing Loans
may, be evidenced by the Notes. Return and cancellation of the "Notes" under the
Original Agreement and issuance of initial Notes under this Agreement shall be
governed by Section 27 hereof. A Revolving Credit Note shall be payable to the
order of each Lender, and a Swing Loan promissory note may, at the Swing
Lender's direction, be payable to the order of the Swing Lender, in an aggregate
principal amount equal to such Lender's Commitment or Swing Lender's commitment
to make Swing Loans, as the case may be. The Borrower irrevocably authorizes
each Lender to make or cause to be made, at or about the time of the Drawdown
Date of any Loan or at the time of receipt of any payment of principal on such
Lender's Notes, an appropriate notation on such Lender's Note Record reflecting
the making of such Revolving Credit Loan, Swing Loan or (as the case may be) the
receipt of such payment. The outstanding amount of the Loans set forth on such
Lender's Note Record shall be PRIMA FACIE evidence of the principal amount
thereof owing and unpaid to such Lender, but the failure to record, or any error
in so recording, any such amount on such Lender's Note Record shall not limit or
otherwise affect the obligations of the Borrower hereunder or under any Note to
make payments of principal of or interest on any Note when due. The
Administrative Agent hereby agrees to provide the Borrower with a statement
concerning the outstanding amount of the Loans, in reasonable detail, on a
monthly basis. Although each Note shall be dated the Closing Date, interest in
respect thereof shall be payable only for the periods during which the Loans
evidenced thereby to the Borrower are outstanding, and although the stated
amount of such Notes shall be equal to the Total Commitment as of the date
hereof, such Notes shall be enforceable, with respect to obligations of the
Borrower to pay the principal amount thereof, only to the extent of the unpaid
principal amount of the Loans to them as of any date of determination.

</Table>

     Such fee shall be payable quarterly, in arrears, on the fifteenth (15th)
day of each January, April, July, and October, or, if all of the Commitments are
terminated pursuant to the terms hereof, such fee shall be prorated to such
termination date from the last date of payment thereof.

     The Facility Fee Percentage to be used in calculating the Facility Fee
shall vary from time to time in accordance with MCRLP's then applicable (if any)
(x) Moody's debt rating, (y) S&P's debt rating and (z) any Third Debt Rating, as
set forth below in this paragraph, and the Facility Fee Percentage shall be
adjusted effective on the next Business Day following any change in MCRLP's
Moody's debt rating or S&P's debt rating or Third Debt Rating, as the case may
be. MCRLP shall notify the Administrative Agent in writing promptly after
becoming aware of any change in any of its debt ratings. In order to qualify for
a Facility Fee Percentage based upon a debt rating, MCRLP shall maintain debt
ratings from at least two (2) nationally recognized rating agencies reasonably
acceptable to the Administrative Agent, one of which must be Moody's or S&P so
long as such Persons are in the business of providing debt ratings for the REIT
industry; PROVIDED that if MCRLP fails to maintain at least two debt ratings,
the Facility Fee Percentage shall be based upon an S&P rating of less than BBB-
in the table above. In addition, MCRLP may, at its option, obtain and maintain
three debt ratings (of which one must be from Moody's or S&P except as set forth
in the previous sentence). If at any time of determination of the Facility Fee
Percentage, (a) MCRLP has then current debt ratings from two (2) rating
agencies, then the Facility Fee Percentage shall be based on the lower of such
ratings, or (b) MCRLP has then current debt ratings from three (3) rating
agencies, then the Facility Fee Percentage shall be based on the lower of the
two highest ratings.

     (g)  ADMINISTRATIVE FEE. The Borrower shall pay to the Administrative Agent

     Section 2.5.   REQUESTS FOR REVOLVING CREDIT LOANS AND SWING LOANS.

     The following provisions shall apply to each request by the Borrower for a

     Completed Revolving Credit Loan Request and Completed Swing Loan Request
     shall be in a minimum amount of $2,000,000 or an integral multiple of
     $500,000 in excess thereof. Each Completed Revolving Credit Loan Request
     and Completed Swing Loan Request shall be irrevocable and binding on the
     Borrower and shall obligate the Borrower to accept the Loans requested from
     the Lenders on the proposed Drawdown Date, unless, in the case of Revolving
     Credit Loans only, such Completed Revolving Credit Loan Request is
     withdrawn (x) in the case of a request for a Revolving Credit LIBOR Rate
     Loan, at least three (3) Business Days prior to the proposed Drawdown Date
     for such Revolving Credit Loan, and (y) in the case of a request for a
     Alternate Base Rate Loan, at least one (1) Business Day prior to the
     proposed Drawdown Date for such Revolving Credit Loan.

          (ii)   Each Completed Revolving Credit Loan Request and Completed
     Swing Loan Request may be delivered by the Borrower to the Administrative
     Agent by 12:00 p.m. noon (New York City time) on any Business Day. In the
     case of Revolving Credit Loans, such delivery shall be at least one (1)
     Business Day prior to the proposed Drawdown Date of any Alternate Base Rate
     Loan, and at least three (3) Business Days prior to the proposed Drawdown
     Date of any Revolving Credit LIBOR Rate Loan; in the case of Swing Loans,

          (iii)  Each Completed Revolving Credit Loan Request and Completed

     or a Swing Loan, (2) the principal amount of the Loan requested, (3) the
     proposed Drawdown Date of such Loan, (4) if a Completed Revolving Credit
     Loan Request, the Interest Period applicable

     to such Revolving Credit Loan, and (5) if a Completed Revolving Credit Loan
     Request, the Type of such Revolving Credit Loan being requested.

          (iv)   No Lender shall be obligated to fund any Revolving Credit Loan

          Swing Loan Request has been timely received by the Administrative
          Agent as provided in subsection (i) above; and

          Credit Loan to be made pursuant to the Completed Revolving Credit Loan
          Request or, as the case may be, to the Swing Loan to be made pursuant
          to the Completed Swing Loan Request, all of the conditions contained
          in Section 10 shall have been satisfied as of the Closing Date and all
          of the conditions set forth in Section 11 shall have been met,
          including, without limitation, the condition under Section 11.1 that
          there be no Default or Event of Default under this Agreement; and

                 (c)  the Administrative Agent shall have received a
          certificate in the form of EXHIBIT D hereto signed by the chief
          financial officer or senior vice president of finance or other thereon
          designated officer of the Borrower setting forth computations
          evidencing compliance with the covenants contained in Sections 9.1 and
          9.6 on a PRO FORMA basis after giving effect to such requested Loan
          (including, to the extent necessary to evidence compliance thereunder,
          the estimated results for all Real Estate to be acquired with the
          proceeds of such requested Loan), and, certifying that, both before
          and after giving effect to such requested Loan, no Default or Event of
          Default exists or will exist under this Agreement or any other Loan
          Document, and that after taking into account such requested Loan, no
          Default or Event of Default will exist as of the Drawdown Date or

     request is received by the Administrative Agent (in the case of an
     Alternate Base Rate Loan or Swing Loan) and on the same day or the Business
     Day following the day a Completed Revolving Credit Loan Request is received
     by the Administrative Agent (in the case of a Revolving Credit LIBOR Rate
     Loan).

     Section 2.6.   CONVERSION OPTIONS.

          (a) The Borrower may elect from time to time by delivering a
Conversion Request in the form of EXHIBIT L to convert any outstanding Revolving
Credit Loan to a Revolving Credit Loan of another Type, PROVIDED that (i) with
respect to any such conversion of a Revolving Credit LIBOR Rate Loan to an
Alternate Base Rate Loan, the Borrower shall give the Administrative Agent at
least three (3) Business Days prior written notice of such election; (ii) with
respect to any such conversion of an Alternate Base Rate Loan to a Revolving
Credit LIBOR Rate Loan, the Borrower shall give the Administrative Agent at
least three (3) LIBOR Business Days prior written notice of such election; (iii)
with respect to any such conversion of a Revolving Credit LIBOR Rate Loan into a
Alternate Base Rate Loan, such conversion shall only be made on the last day of
the Interest Period with respect thereto unless the Borrower pays the related
LIBOR Breakage Costs at the time of such conversion and (iv) no Revolving Credit
Loan may be converted into a Revolving Credit LIBOR Rate Loan when any Default
or Event of Default has occurred and is continuing. All or any part of
outstanding Revolving Credit Loans of any Type may be converted into a Revolving
Credit Loan of another Type as provided herein, PROVIDED that any partial
conversion shall be in an aggregate principal amount of $2,000,000 or a integral
multiple of $500,000 in excess thereof. Each Conversion Request relating to the
conversion of a Alternate Base Rate Loan to a Revolving Credit LIBOR Rate Loan
shall be irrevocable by the Borrower.

          (b) Any Revolving Credit Loan of any Type may be continued as such
upon the expiration of the Interest Period with respect thereto (i) in the case
of Alternate Base Rate Loans, automatically and (ii) in the case of Revolving
Credit LIBOR Rate Loans by compliance by the Borrower with the notice provisions
contained in Section 2.6(a) or (c); PROVIDED that no Revolving Credit LIBOR Rate
Loan may be continued as such when any Default or Event of Default has occurred
and is continuing but shall be automatically converted to a Alternate Base Rate
Loan on the last day of the first Interest Period relating thereto ending during
the continuance of any Default or Event of Default. The Administrative Agent
shall notify the Lenders promptly when any such automatic conversion
contemplated by this Section 2.6(b) is scheduled to occur.

          (c) In the event that the Borrower does not notify the Administrative
Agent of its election hereunder with respect to the continuation of any
Revolving Credit LIBOR Rate Loan as such, the affected Revolving Credit LIBOR
Rate Loan shall automatically be continued as a Revolving Credit LIBOR Rate Loan
with an Interest Period of one (1) month at the end of the applicable Interest
Period other than during the continuance of a Default or

<Page>
                                      -39-

Event of Default, in which case it will be continued as a Alternate Base Rate
Loan at the end of the applicable Interest Period. In such event, the Borrower
shall be deemed to have requested a Revolving Credit LIBOR Rate Loan hereunder
and shall be subject to all provisions of this Agreement relating to LIBOR Rate
Loans, including, without limitation, those set forth in Sections 4.5, 4.6, and
4.8 hereof.

          (d) The Borrower may not request or elect a Revolving Credit LIBOR
Rate Loan pursuant to Section 2.5, elect to convert a Alternate Base Rate Loan
to a Revolving Credit LIBOR Rate Loan pursuant to Section 2.6(a), elect to
continue a Revolving Credit LIBOR Rate Loan pursuant to Section 2.6(b) or have
continued a Revolving Credit LIBOR Rate Loan pursuant to Section 2.6(c) if,
after giving effect thereto, there would be greater than twenty (20) Revolving
Credit LIBOR Rate Loans then outstanding. Any Loan Request for a Revolving
Credit LIBOR Rate Loan that would create greater than twenty (20) Revolving
Credit LIBOR Rate Loans outstanding shall be deemed to be a Loan Request for a
Alternate Base Rate Loan.

     Section 2.7.   FUNDS FOR REVOLVING CREDIT LOANS AND SWING LOANS.

          (a) Subject to the other provisions of this Section 2, not later
than 12:00 p.m. (New York City time) on the proposed Drawdown Date of any
Revolving Credit Loan and not later than 1:00 p.m. (New York City time) on the
proposed Drawdown Date of any Swing Loan, each of the Lenders (or in the case of
a Swing Loan, the Swing Lender) will make available to the Administrative Agent,
at the Administrative Agent's Head Office, in immediately available funds, the
amount of such Lender's Commitment Percentage of the amount of the requested
Revolving Credit Loan, or, in the case of a Swing Loan, the requested Swing Loan
amount; PROVIDED that each Lender shall provide notice to the Administrative
Agent of its intent not to make available its Commitment Percentage of any
requested Revolving Credit Loan as soon as possible after receipt of any
Completed Revolving Credit Loan Request, and in any event not later than 4:00
p.m. (New York City time) on (x) the Business Day prior to the Drawdown Date of
any requested Alternate Base Rate Loan and (y) the third Business Day prior to
the Drawdown Date of any requested Revolving Credit LIBOR Rate Loan. Upon
receipt from each Lender of such amount, the Administrative Agent will make
available to the Borrower, in the Borrower's account with the Administrative
Agent or as otherwise directed to the Administrative Agent by the Borrower, the
aggregate amount of such Loan made available to the Administrative Agent by the
Lenders; all such funds received by the Administrative Agent by the times set
forth above will be made available to the Borrower not later than 2:00 p.m. on
the same Business Day. Funds received after such time will be made available by
not later than 12:00 p.m. on the next Business Day. The Administrative Agent
hereby agrees to

<Page>

                                      -40-

promptly provide the Borrower with a statement confirming the particulars of
each Revolving Credit LIBOR Rate Loan, in reasonable detail, when each such Loan
is made. The failure or refusal of any Lender to make available to the
Administrative Agent at the aforesaid time and place on any Drawdown Date the
amount of its Commitment Percentage of the requested Revolving Credit Loan shall
not relieve any other Lender from its several obligation hereunder to make
available to the Administrative Agent the amount of its Commitment Percentage of
any requested Revolving Credit Loan but in no event shall the Administrative
Agent (in its capacity as Administrative Agent) have any obligation to make any
funding or shall any Lender be obligated to fund more than its Commitment
Percentage of the requested Revolving Credit Loan or to increase its Commitment
Percentage on account of such failure or otherwise.

          (b) The Administrative Agent may, unless notified to the contrary
by any Lender prior to a Drawdown Date, assume that such Lender has made
available to the Administrative Agent on such Drawdown Date the amount of such
Lender's Commitment Percentage of the Loan to be made on such Drawdown Date, and
the Administrative Agent may (but it shall not be required to), in reliance upon
such assumption, make available to the Borrower a corresponding amount. If any
Lender makes available to the Administrative Agent such amount on a date after
such Drawdown Date, such Lender shall pay to the Administrative Agent on demand
an amount equal to the product of (i) the average, computed for the period
referred to in clause (iii) below, of the weighted average interest rate paid by
the Administrative Agent for federal funds acquired by the Administrative Agent
during each day included in such period, MULTIPLIED BY (ii) the amount of such
Lender's Commitment Percentage of such Revolving Credit Loan, MULTIPLIED BY
(iii) a fraction, the numerator of which is the number of days that elapsed from
and including such Drawdown Date to the date on which the amount of such
Lender's Commitment Percentage of such Revolving Credit Loan shall become
immediately available to the Administrative Agent, and the denominator of which
is 360. A statement of the Administrative Agent submitted to such Lender with
respect to any amounts owing under this paragraph shall be PRIMA FACIE evidence
of the amount due and owing to the Administrative Agent by such Lender. If the
amount of such Lender's Commitment Percentage of such Revolving Credit Loans is
not made available to the Administrative Agent by such Lender within three (3)
Business Days following such Drawdown Date, the Administrative Agent shall be
entitled to recover such amount from the Borrower on demand, with interest
thereon at the rate per annum applicable to the Revolving Credit Loans made on
such Drawdown Date.

     Section 2.8.   REPAYMENT OF THE REVOLVING CREDIT LOANS AND SWING LOANS AT
MATURITY. The Borrower promises to pay on the Maturity Date, and there shall
become absolutely due and payable on the Maturity Date, all unpaid principal of

<Page>

                                      -41-

the Revolving Credit Loans and Swing Loans outstanding on such date, together
with any and all accrued and unpaid interest thereon, the unpaid balance of the
Commitment Fee or Facility Fee accrued through such date, and any and all other
unpaid amounts due under this Agreement, the Notes or any other of the Loan
Documents.

     Section 2.9.   OPTIONAL REPAYMENTS OF REVOLVING CREDIT LOANS AND SWING
LOANS. The Borrower shall have the right, at its election, to prepay the
outstanding amount of the Revolving Credit Loans and Swing Loans, in whole or in
part, at any time without penalty or premium; PROVIDED that the outstanding
amount of any Revolving Credit LIBOR Rate Loans may not be prepaid unless the
Borrower pays any LIBOR Breakage Costs for each Revolving Credit LIBOR Rate Loan
so prepaid at the time of such prepayment. The Borrower shall give the
Administrative Agent, no later than 11:00 a.m., New York City time, at least one
(1) Business Day's prior written notice of any prepayment pursuant to this
Section 2.9 of any Alternate Base Rate Loans, and at least three (3) LIBOR
Business Days' notice of any proposed prepayment pursuant to this Section 2.9 of
Revolving Credit LIBOR Rate Loans, specifying the proposed date of prepayment of
Revolving Credit Loans and the principal amount to be prepaid. Same day notice
is permitted for prepayment pursuant to this Section 2.9 of Swing Loans so long
as such notice is delivered not later than 12:00 p.m. (New York City time). Each
such partial prepayment shall be in an amount of $2,000,000 or integral multiple
of $500,000 in excess thereof or, if less, the outstanding balance of the
Revolving Credit Loans or Swing Loans then being repaid, shall be accompanied by
the payment of all charges outstanding on all Revolving Credit Loans or Swing
Loans so prepaid and of all accrued interest on the principal prepaid to the
date of payment, and shall be applied, in the absence of instruction by the
Borrower, first to the principal of Swing Loans, then to Alternate Base Rate
Loans and then to the principal of Revolving Credit LIBOR Rate Loans, at the
Administrative Agent's option.

     Section 2.10.  REDUCTION OF TOTAL COMMITMENT. The Borrower shall have the
right at any time and from time to time upon five (5) Business Days prior
written notice to the Administrative Agent to reduce by $10,000,000 or an
integral multiple thereof or terminate entirely the unborrowed portion of the
Total Commitment (with outstanding Letters of Credit and Swing Loans to be
considered as being borrowed for the purposes hereof), whereupon the Commitments
of the Lenders shall be reduced pro rata in accordance with their respective
Commitment Percentages of the amount specified in such notice or, as the case
may be, terminated. Promptly after receiving any notice of the Borrower
delivered pursuant to this Section 2.10, the Administrative Agent will notify
the Lenders of the substance thereof. Upon the effective date of any such
reduction or termination, the Borrower shall pay to the Administrative Agent for
the respective accounts of the Lenders the full amount of any Facility Fee

<Page>

                                      -42-

then accrued on the amount of the reduction. No reduction of the Commitments may
be reinstated.

     Section 2A.    COMPETITIVE BID LOANS.

     Section 2A.1.  THE COMPETITIVE BID OPTIONS. In addition to the Revolving
Credit Loans and Swing Loans made pursuant to Section 2 hereof, and provided
that at the time of such request no Default or Event of Default has occurred and
is continuing and MCRLP maintains an Investment Grade Credit Rating from two
nationally-recognized rating agencies reasonably acceptable to the
Administrative Agent (one of which must be Moody's or S&P so long as such
Persons are in the business of providing debt ratings for the REIT industry),
the Borrower may from time to time request Competitive Bid Loans pursuant to the
terms of this Section 2A. The Lenders may, but shall have no obligation to, make
such offers and the Borrower may, but shall have no obligation to, accept such
offers in the manner set forth in this Section 2A. Notwithstanding any other
provision herein to the contrary, at no time shall the aggregate principal
amount of Competitive Bid Loans outstanding at any time exceed the lesser of (a)
the Total Commitment minus the sum of (i) the aggregate outstanding principal
amount of Revolving Credit Loans and Swing Loans, plus (ii) the Maximum Drawing
Amount of Letters of Credit outstanding at such time, or (b) $300,000,000.

     Section 2A.2.  COMPETITIVE BID LOAN ACCOUNTS: COMPETITIVE BID NOTES.

          (a) The obligation of the Borrower to repay the outstanding
principal amount of any and all Competitive Bid Loans, plus interest at the
applicable Competitive Bid Rate or the sum of the Competitive Bid Margin plus
the applicable LIBOR Rate (as the case may be) accrued thereon, shall be
evidenced by this Credit Agreement and by individual loan accounts (the
"COMPETITIVE BID LOAN ACCOUNTS" and individually, a "COMPETITIVE BID LOAN
ACCOUNT") maintained by the Administrative Agent on its books for each of the
Lenders, it being the intention of the parties hereto that, except as provided
for in paragraph (b) of this Section 2A.2, the Borrower's obligations with
respect to Competitive Bid Loans are to be evidenced only as stated herein and
not by separate promissory notes and shall hereby constitute an absolute promise
to pay when due, without notice, demand, presentment or setoff.

          (b) Any Lender may at any time, and from time to time, request that
any Competitive Bid Loans outstanding to such Lender be evidenced by a
promissory note of the Borrower in substantially the form of EXHIBIT G hereto
(each, a "COMPETITIVE BID NOTE"), dated as of the Closing Date and completed
with appropriate insertions. One Competitive Bid Note shall be payable to the
order of each Lender in an amount equal to the principal amount of the
Competitive Bid Loan made by such Lender to the Borrower, and representing

<Page>

                                      -43-

the obligation of the Borrower to pay such Lender such principal amount or, if
less, the outstanding principal amount of any and all Competitive Bid Loans made
by such Lender, plus interest at the applicable Competitive Bid Rate or the sum
of the Competitive Bid Margin plus the applicable LIBOR Rate accrued thereon, as
set forth herein. Upon execution and delivery by the Borrower of a Competitive
Bid Note, the Borrower's obligation to repay any and all Competitive Bid Loans
made to them by such Lender and all interest thereon shall thereafter be
evidenced by such Competitive Bid Note.

          (c) The Borrower irrevocably authorizes (i) each Lender to make or
cause to be made, in connection with a Drawdown Date of any Competitive Bid Loan
or at the time of receipt of any payment of principal on such Lender's
Competitive Bid Note in the case of a Competitive Bid Note, and (ii) the
Administrative Agent to make or cause to be made, in connection with a Drawdown
Date of any Competitive Bid Loan or at the time of receipt of any payment of
principal on such Lender's Competitive Bid Loan Account in the case of a
Competitive Bid Loan Account, an appropriate notation on such Lender's records
or on the schedule attached to such Lender's Competitive Bid Note or a
continuation of such schedule attached thereto, or the Administrative Agent's
records, as applicable, reflecting the making of the Competitive Bid Loan or the
receipt of such payment (as the case may be) and may, prior to any transfer of a
Competitive Bid Note, endorse on the reverse side thereof the outstanding
principal amount of Competitive Bid Loans evidenced thereby. The outstanding
amount of the Competitive Bid Loans set forth on such Lender's record or the
Administrative Agent's records, as applicable, shall be PRIMA FACIE evidence of
the principal amount thereof owing and unpaid to such Lender, but the failure to
record, or any error in so recording, any such amount shall not limit or
otherwise affect the obligations of the Borrower hereunder to make payments of
principal of or interest on any Competitive Bid Loan when due.

     Section 2A.3.  COMPETITIVE BID QUOTE REQUEST; INVITATION FOR COMPETITIVE
BID QUOTES.

          (a) When the Borrower wishes to request offers to make Competitive
Bid Loans under this Section 2A, it shall transmit to the Administrative Agent
by telex or facsimile a Competitive Bid Quote Request substantially in the form
of EXHIBIT H hereto (a "COMPETITIVE BID QUOTE REQUEST") so as to be received no
later than 11:00 a.m. (New York City time) (i) four (4) Business Days prior to
the requested Drawdown Date in the case of a Competitive Bid Loan bearing
interest calculated by reference to the LIBOR Rate (a "LIBOR COMPETITIVE BID
LOAN") or (ii) one (1) Business Day prior to the requested Drawdown Date in the
case of an Competitive Bid Loan bearing interest calculated by reference to a
fixed rate of interest (an "ABSOLUTE COMPETITIVE BID LOAN"), specifying:

<Page>

                                      -44-

                  (A)  the requested Drawdown Date (which must be a Business
Day);

                  (B)  the aggregate amount of such Competitive Bid Loans, which
shall be $5,000,000 or larger multiple of $1,000,000;

                  (C)  the duration of the Interest Period applicable thereto,
subject to the provisions of the definition of Interest Period; and

                  (D)  whether the Competitive Bid Quotes requested are for
LIBOR Competitive Bid Loans or Absolute Competitive Bid Loans.

The Borrower may request offers to make Competitive Bid Loans for more than one
Interest Period in a single Competitive Bid Quote Request. No new Competitive
Bid Quote Request shall be given until the Borrower has notified the
Administrative Agent of its acceptance or non-acceptance of the Competitive Bid
Quotes relating to any outstanding Competitive Bid Quote Request.

          (b) Promptly upon receipt of a Competitive Bid Quote Request, the
Administrative Agent shall send to the Lenders by telecopy or facsimile
transmission an Invitation for Competitive Bid Quotes substantially in the form
of EXHIBIT I hereto, which shall constitute an invitation by the Borrower to
each Lender to submit Competitive Bid Quotes in accordance with this Section 2A.

     Section 2A.4.  ALTERNATIVE MANNER OF PROCEDURE. If, after receipt by the
Administrative Agent and each of the Lenders of a Competitive Bid Quote Request
from the Borrower in accordance with Section 2A.3, the Administrative Agent or
any Lender shall be unable to complete any procedure of the auction process
described in Sections 2A.5 through 2A.6 (inclusive) due to the inability of such
Person to transmit or receive communications through the means specified
therein, such Person may rely on telephonic notice for the transmission or
receipt of such communications. In any case where such Person shall rely on
telephone transmission or receipt, any communication made by telephone shall, as
soon as possible thereafter, be followed by written confirmation thereof.

     Section 2A.5.  SUBMISSION AND CONTENTS OF COMPETITIVE BID QUOTES.

          (a) Each Lender may, but shall be under no obligation to, submit a
Competitive Bid Quote containing an offer or offers to make Competitive Bid
Loans in response to any Competitive Bid Quote Request. Each Competitive Bid
Quote must comply with the requirements of this Section 2A.5 and must be
submitted to the Administrative Agent by telex or facsimile transmission at its

on the third LIBOR Business Day prior to the proposed Drawdown Date, in the case
of a LIBOR Competitive Bid Loan or (ii) 10:00 a.m. (New York City time) on the
proposed Drawdown Date, in the case of an Absolute Competitive Bid Loan,
provided that Competitive Bid Quotes may be submitted by the Administrative
Agent in its capacity as a Lender only if it submits its Competitive Bid Quote

Lenders, in the case of a LIBOR Competitive Bid Loan or (y) 15 minutes prior to
the deadline for the other Lenders, in the case of an Absolute Competitive Bid
Loan. Subject to the provisions of Sections 10 and 11 hereof, any Competitive
Bid Quote so made shall be irrevocable except with the written consent of the
Administrative Agent given on the instructions of the Borrower.

          (b) Each Competitive Bid Quote shall be in substantially the form
of EXHIBIT J hereto and shall in any case specify:

                  (i)    the proposed Drawdown Date;

                  (ii)   the principal amount of the Competitive Bid Loan for
which each proposal is being made, which principal amount (w) may be greater
than or less than the Commitment of the quoting Lender, (x) must be $1,000,000
or a larger multiple of $500,000, (y) may not exceed the aggregate principal
amount of Competitive Bid Loans for which offers were requested and (z) may be

Loans for which offers being made by such quoting Lender may be accepted;

                  (iii)  the Interest Periods for which Competitive Bid Quotes
are being submitted;

                  (iv)   in the case of a LIBOR Competitive Bid Loan, the margin

for each such Competitive Bid Loan, expressed as a percentage (specified to the
nearest 1/10,000th of 1%) to be added to or subtracted from such LIBOR Rate;

                  (v)    in the case of an Absolute Competitive Bid Loan, the
rate of interest per annum (specified to the nearest 1/10,000th of 1%) (the
"COMPETITIVE BID RATE") offered for each such Absolute Competitive Bid Loan; and

                  (vi)   the identity of the quoting Lender.

A Competitive Bid Quote may include up to five (5) separate offers by the

<Page>

                                      -46-

in Section 10.18, be funded by a Lender's Designated Bank. A Lender making a
Competitive Bid Quote may, but shall not be required to, specify in its
Competitive Bid Quote whether the related Competitive Bid Loans are intended to
be funded by such Lender's Designated Bank, as provided in Section 18.10.

          (c) Any Competitive Bid Quote shall be disregarded if it:

                  (i)    is not substantially in the form of EXHIBIT J
hereto;

                  (ii)   contains qualifying, conditional or similar
language;

                  (iii)  proposes terms other than or in addition to those
set forth in the applicable Invitation for Competitive Bid Quotes; or

                  (iv)   arrives after the time set forth in Section 2A.5(a)
hereof.

     Section 2A.6.  NOTICE TO BORROWER. The Administrative Agent shall promptly
notify the Borrower of the terms (a) of any Competitive Bid Quote submitted by a
Lender that is in accordance with Section 2A.5 and (b) of any Competitive Bid
Quote that amends, modifies or is otherwise inconsistent with a previous
Competitive Bid Quote submitted by such Lender with respect to the same
Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall
be disregarded by the Administrative Agent unless such subsequent Competitive
Bid Quote is submitted solely to correct a manifest error in such former
Competitive Bid Quote and was received by the Administrative Agent within the
time period required in Section 2A.5(a) for receipt of Competitive Bid Quotes.
The Administrative Agent's notice to the Borrower shall specify (i) the
aggregate principal amount of Competitive Bid Loans for which offers have been
received for each Interest Period specified in the related Competitive Bid Quote
Request, (ii) the respective principal amounts and Competitive Bid Margins or
Competitive Bid Rates, as the case may be, so offered, and the identity of the
respective Lenders submitting such offers, and (iii) if applicable, limitations
on the aggregate principal amount of Competitive Bid Loans for which offers in
any single Competitive Bid Quote may be accepted.

Not later than 11:00 a.m. (New York City time) on (a) the third Business Day
prior to the proposed Drawdown Date, in the case of a LIBOR Competitive Bid Loan
or (b) the proposed Drawdown Date, in the case of an Absolute Competitive Bid
Loan, the Borrower shall notify the Administrative Agent of its acceptance or
non-acceptance of each Competitive Bid Quote in substantially the form of
EXHIBIT K hereto. The Borrower may accept any Competitive Bid Quote in whole or
in part; PROVIDED THAT:

<Page>

                                      -47-

                  (i)    the aggregate principal amount of each Competitive Bid
Loan may not exceed the applicable amount set forth in the related Competitive
Bid Quote Request;

                  (ii)   acceptance of offers may only be made on the basis of
ascending Competitive Bid Margins or Competitive Bid Rates, as the case may be,
and

                  (iii)  the Borrower may not accept any offer that is described
in Section 2A.5(c) or that otherwise fails to comply with the requirements of
this Agreement.

The Administrative Agent shall promptly notify each Lender which submitted a
Competitive Bid Quote of the Borrower's acceptance or non-acceptance thereof. At
the request of any Lender which submitted a Competitive Bid Quote and with the
consent of the Borrower, the Administrative Agent will promptly notify all
Lenders which submitted Competitive Bid Quotes of (a) the aggregate principal
amount of, and (b) the range of Competitive Bid Rates or Competitive Bid Margins
of, the accepted Competitive Bid Loans for each requested Interest Period.

     Section 2A.8. ALLOCATION BY ADMINISTRATIVE AGENT. If offers are made by two
(2) or more Lenders with the same Competitive Bid Margin or Competitive Bid
Rate, as the case may be, for a greater aggregate principal amount than the
amount in respect of which offers are accepted for the related Interest Period,
the principal amount of Competitive Bid Loans in respect of which such offers
are accepted shall be allocated by the Administrative Agent among such Lenders
as nearly as possible (in such multiples, not less than $1,000,000, as the
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determination by the Administrative Agent of
the amounts of Competitive Bid Loans shall be conclusive in the absence of
manifest error.

     Section 2A.9. FUNDING OF COMPETITIVE BID LOANS. If, on or prior to the
Drawdown Date of any Competitive Bid Loan, the Total Commitment has not
terminated in full and if, on such Drawdown Date, the applicable conditions of
Sections 10 and 11 hereof are satisfied, and the Administrative Agent shall have
received a certificate in the form of EXHIBIT D hereto, the Lender or Lenders
whose offers the Borrower has accepted will fund each Competitive Bid Loan so
accepted. Such Lender or Lenders will make such Competitive Bid Loans by
crediting the Administrative Agent for further credit to the Borrower's
specified account with the Administrative Agent, in immediately available funds
not later than 1:00 p.m. (New York City time) on such Drawdown Date.

                                      -48-

     Section 2A.10. FUNDING LOSSES. If, after acceptance of any Competitive Bid
Quote pursuant to Section 2A, the Borrower (a) fails to borrow any Competitive
Bid Loan so accepted on the date specified therefor, or (b) repays the
outstanding amount of the Competitive Bid Loan on or prior to the last day of
the Interest Period relating thereto, the Borrower shall indemnify the Lender
making such Competitive Bid Quote or funding such Competitive Bid Loan against
any loss or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Lender to fund or maintain such
unborrowed Loans, including, without limitation compensation as provided in
Section 4.8.

     Section 2A.11. REPAYMENT OF COMPETITIVE BID LOANS; INTEREST. The principal
of each Competitive Bid Loan shall become absolutely due and payable by the
Borrower on the last day of the Interest Period relating thereto, and the
Borrower hereby absolutely and unconditionally promises to pay to the
Administrative Agent for the account of the relevant Lenders at or before 1:00
p.m. (New York City time) on the last day of the Interest Periods relating
thereto the principal amount of all such Competitive Bid Loans, plus interest
thereon at the applicable Competitive Bid Rates or the sum of the Competitive
Bid Margin plus the applicable LIBOR Rate (as the case may be). The Competitive
Bid Loans shall bear interest at the rate per annum specified in the applicable
Competitive Bid Quotes. Interest on the Competitive Bid Loans shall be payable
(a) on the last day of the applicable Interest Periods, and if any such Interest
Period is longer than three months, also on the last day of the third month
following the commencement of such Interest Period, and (b) on the Maturity Date
for all Loans. Subject to the terms of this Credit Agreement, the Borrower may
make Competitive Bid Quote Requests with respect to new borrowings of any
amounts so repaid prior to the Maturity Date. The provisions of Section 2.6
shall not apply to Competitive Bid Loans.

     Section 2A.12. OPTIONAL REPAYMENT OF COMPETITIVE BID LOANS. The Borrower
shall have the right, at its election, to repay the outstanding amount of any of
the Competitive Bid Loans, as a whole or in part, at any time without penalty or
premium, PROVIDED that any full or partial prepayment of the outstanding amount
of any Competitive Bid Loan pursuant to this Section 2A.12 may be made only on
the last day of the Interest Period relating thereto, or, if made prior to such
date, shall be made subject to the provisions of Section 2A.10 hereof. The
Borrower shall give the Administrative Agent no less than three (3) Business
Days notice of any proposed prepayment pursuant to this Section 2A.12,
specifying the proposed date of prepayment of the Competitive Bid Loan and the
principal amount to be prepaid. Each such partial prepayment of any Competitive

by the payment of accrued interest on the principal prepaid to the date of
prepayment.

                                      -49-

     Section 3.1.   LETTER OF CREDIT COMMITMENTS.

          Section 3.1.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the
terms and conditions hereof and the execution and delivery by the Borrower of a
letter of credit application on the Fronting Bank's customary form as part of a
Completed Revolving Credit Loan Request (a "LETTER OF CREDIT APPLICATION"), the
Fronting Bank on behalf of the Lenders and in reliance upon the agreement of the
Lenders set forth in Section 3.1.4 and upon the representations and warranties
of the Borrower contained herein, agrees, in its individual capacity, to issue,
extend and renew for the account of the Borrower one or more standby or
documentary letters of credit (individually, a "LETTER OF CREDIT"), in such form
as may be requested from time to time by the Borrower and reasonably agreed to
by the Fronting Bank; PROVIDED, HOWEVER, that, after giving effect to such
Completed Revolving Credit Loan Request, (a) the Maximum Drawing Amount shall
not exceed $100,000,000 at any one time and (b) the sum of (i) the Maximum
Drawing Amount on all Letters of Credit and (ii) the amount of all Revolving
Credit Loans, Swing Loans and Competitive Bid Loans outstanding shall not exceed
the Total Commitment in effect at such time. The Fronting Bank shall give the
Administrative Agent prompt notice of the issuance of each Letter of Credit, and
the Administrative Agent shall forward such notice to Lenders in accordance with
Section 14.12.

          Section 3.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
Application shall be completed to the reasonable satisfaction of the
Administrative Agent and the Fronting Bank. In the event that any provision of
any Letter of Credit Application shall be inconsistent with any provision of
this Agreement (including provisions applicable to a Completed Revolving Credit
Loan Request), then the provisions of this Agreement shall, to the extent of any
such inconsistency, govern.

          Section 3.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit
issued, extended or renewed hereunder shall, among other things, (i) provide for
the payment of sight drafts for honor thereunder when presented in accordance
with the terms thereof and when accompanied by the documents described therein,
and (ii) have an expiry date no later than the earlier of (x) one year from the
date of issuance or (y) the date which is thirty (30) days prior to the Maturity
Date. Each Letter of Credit so issued, extended or renewed shall be subject to
the Uniform Customs.

          Section 3.1.4. REIMBURSEMENT OBLIGATIONS OF LENDERS. Each Lender
severally agrees that it shall be absolutely liable, without regard to the
occurrence of any Default or Event of Default or any other condition precedent
whatsoever, to the extent of such Lender's Commitment Percentage, to

<Page>

                                      -50-

reimburse the Fronting Bank on demand pursuant to Section 3.3 for the amount of
each draft paid by the Fronting Bank under each Letter of Credit to the extent
that such amount is not reimbursed by the Borrower pursuant to Section 3.2 (such
agreement for a Lender being called herein the "LETTER OF CREDIT PARTICIPATION"
of such Lender).

     Section 3.2.   REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce
the Fronting Bank to issue, extend and renew each Letter of Credit and the
Lenders to participate therein, the Borrower hereby agrees, except as
contemplated in Section 3.3 below, to reimburse or pay to the Fronting Bank, for
the account of the Fronting Bank or (as the case may be) the Lenders, with
respect to each Letter of Credit issued, extended or renewed by the Fronting
Bank hereunder,

          (a) except as otherwise expressly provided in Section 3.2(b) or
Section 3.3, on each date that any draft presented under such Letter of Credit
is honored in accordance with its terms by the Fronting Bank, or the Fronting
Bank otherwise makes a payment with respect thereto in accordance with
applicable law, (i) the amount paid by the Fronting Bank under or with respect
to such Letter of Credit, and (ii) any amounts payable pursuant to Section 4.5
hereof under, or with respect to, such Letter of Credit, and

          (b) upon the termination of the Total Commitment, or the acceleration
of the Reimbursement Obligations with respect to all Letters of Credit in
accordance with Section 12, an amount equal to the then Maximum Drawing Amount
on all Letters of Credit, which amount shall be held by the Administrative Agent
as cash collateral for the benefit of the Fronting Bank, the Lenders and the
Administrative Agent for all Reimbursement Obligations.

     Each such payment shall be made to the Administrative Agent at the
Administrative Agent's Head Office in immediately available funds. Interest on
any and all amounts not converted to a Revolving Credit Loan pursuant to Section
3.3 and remaining unpaid by the Borrower under this Section 3.2 at any time from
the date such amounts become due and payable (whether as stated in this Section
3.2, by acceleration or otherwise) until payment in full (whether before or
after judgment) shall be payable to the Administrative Agent for the benefit of
the Lenders on demand at the rate specified in Section 4.9 for overdue principal
on the Revolving Credit Loans.

     Section 3.3.   LETTER OF CREDIT PAYMENTS; FUNDING OF A LOAN. If any draft
shall be presented or other demand for payment shall be made under any Letter of
Credit, the Fronting Bank shall notify the Borrower and the Lenders of the date
and amount of the draft presented or demand for payment and of the date and time
when it expects to pay such draft or honor such demand for payment, and, except
as provided in this Section 3.3, the Borrower shall reimburse Administrative

<Page>

                                      -51-

Agent, as set forth in Section 3.2 above. Notwithstanding anything contained in
Section 3.2 above or this Section 3.3 to the contrary, however, unless the
Borrower shall have notified the Administrative Agent and the Fronting Bank
prior to 11:00 a.m. (New York time) on the Business Day immediately prior to the
date of such drawing that the Borrower intends to reimburse the Fronting Bank
for the amount of such drawing with funds other than the proceeds of the Loans,
the Borrower shall be deemed to have timely given a Completed Revolving Credit
Loan Request pursuant to Section 2.5 to the Administrative Agent, requesting a
Alternate Base Rate Loan on the date on which such drawing is honored and in an
amount equal to the amount of such drawing. The Borrower may thereafter convert
any such Alternate Base Rate Loan to a Revolving Credit Loan of another Type in
accordance with Section 2.6. Each Lender shall, in accordance with Section 2.7,
make available such Lender's Commitment Percentage of such Revolving Credit Loan
to the Administrative Agent, the proceeds of which shall be applied directly by
the Administrative Agent to reimburse the Fronting Bank for the amount of such
draw. In the event that any Lender fails to make available to the Administrative
Agent the amount of such Lender's Commitment Percentage of such Revolving Credit
Loan on the date of the drawing, the Administrative Agent shall be entitled to
recover such amount on demand from such Lender plus any additional amounts
payable under Section 2.7(b) in the event of a late funding by a Lender. The
Fronting Bank is irrevocably authorized by the Borrower and each of the Lenders
to honor draws on each Letter of Credit by the beneficiary thereof in accordance
with the terms of the Letter of Credit. The responsibility of the Fronting Bank
to the Borrower and the Lenders shall be only to determine that the documents
(including each draft) delivered under each Letter of Credit in connection with
such presentment shall be in conformity in all material respects with such
Letter of Credit.

     Section 3.4.   OBLIGATIONS ABSOLUTE. The Borrower's obligations under this
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Administrative Agent, the
Fronting Bank, any Lender or any beneficiary of a Letter of Credit. The Borrower
further agrees with the Administrative Agent, the Fronting Bank and the Lenders
that the Administrative Agent, the Fronting Bank and the Lenders shall not be
responsible for, and the Borrower's Reimbursement Obligations under Section 3.2
shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon (so long as the documents delivered
under each Letter of Credit in connection with such presentment shall be in the
form required by, and in conformity in all material respects with, such Letter
of Credit), even if such documents should in fact prove to be in any or all
respects invalid, fraudulent or forged, or any dispute between or among any of
the Borrower, the beneficiary of any Letter of Credit or any

<Page>

                                      -52-

financing institution or other party to whom any Letter of Credit may be
transferred, or any claims or defenses whatsoever of the Borrower against the
beneficiary of any Letter of Credit or any such transferee. If done in good
faith and absent gross negligence, the Administrative Agent, the Fronting Bank
and the Lenders shall not be liable for any error, omission, interruption or
delay in transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit. The Borrower agrees that
any action taken or omitted by the Administrative Agent, the Fronting Bank or
any Lender under or in connection with each Letter of Credit and the related
drafts and documents, if done in good faith and absent gross negligence, shall
be binding upon the Borrower and shall not result in any liability on the part
of the Administrative Agent, the Fronting Bank or any Lender to the Borrower.

     Section 3.5.   RELIANCE BY ISSUER. To the extent not inconsistent with
Section 3.4, the Administrative Agent and the Fronting Bank shall be entitled to
rely, and shall be fully protected in relying upon, any Letter of Credit, draft,
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document 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, independent accountants and other experts selected by the
Administrative Agent or the Fronting Bank. The Administrative Agent and the
Fronting Bank shall in all cases be fully protected by the Lenders in acting, or
in refraining from acting, under this Section 3 in accordance with a request of
the Majority Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon the Lenders and all future holders of the
Notes or of a Letter of Credit Participation.

     Section 3.6.   LETTER OF CREDIT FEE. The Borrower shall pay to the
Administrative Agent a fee (in each case, a "LETTER OF CREDIT FEE") in an amount
equal to the Applicable L/C Percentage of the face amount of each outstanding
Letter of Credit, which fee (a) shall be payable quarterly in arrears on the
first day of each calendar quarter for the immediately preceding calendar
quarter, with a final payment on the Maturity Date or any earlier date on which
the Commitments shall terminate (which Letter of Credit Fee shall be pro-rated
for any calendar quarter in which such Letter of Credit is issued, drawn upon or
otherwise reduced or terminated) and (b) shall be for the accounts of the
Lenders as follows: (i) an amount equal to 0.125% per annum of the face amount
of the Letter of Credit shall be for the account of the Fronting Bank and (ii)
the remainder of the Letter of Credit Fee shall be for the accounts of the
Lenders (including the Fronting Bank) pro rata in accordance with their
respective Commitment Percentages. In respect of each Letter of Credit, the
Borrower shall also pay to the Fronting Bank for the Fronting Bank's own
account, at such other time or times as such charges are customarily made by the
Fronting

<Page>

                                      -53-

Bank, the Fronting Bank's customary issuance, amendment, negotiation or
document examination and other administrative fees as in effect from time to
time.

     Section 3.7.   EXISTING LETTERS OF CREDIT. Those letters of credit issued
for the account of the Borrower by the Fronting Bank under the Original
Agreement prior to its being amended and restated by this Agreement and which
are outstanding on the date hereof, which Letters of Credit are identified on
SCHEDULE 3.7 hereto (the "EXISTING LETTERS OF CREDIT"), shall for all purposes
be deemed to be Letters of Credit issued under this Agreement.

     Section 4.     CERTAIN GENERAL PROVISIONS.

     Section 4.1.   FUNDS FOR PAYMENTS.

          (a) All payments of principal, interest, fees, and any other amounts
due hereunder or under any of the other Loan Documents shall be made to the
Administrative Agent, for the respective accounts of the Lenders or (as the case
may be) the Administrative Agent, at the Administrative Agent's Head Office, in
each case in Dollars and in immediately available funds.

          (b) All payments by the Borrower hereunder and under any of the other
Loan Documents shall be made without setoff or counterclaim and free and clear
of and without deduction for any taxes, levies, imposts, duties, charges, fees,
deductions, withholdings, compulsory liens, restrictions or conditions of any
nature now or hereafter imposed or levied by any jurisdiction or any political
subdivision thereof or taxing or other authority therein unless the Borrower is
compelled by law to make such deduction or withholding. If any such obligation
is imposed upon the Borrower with respect to any amount payable by it hereunder
or under any of the other Loan Documents, the Borrower shall pay to the
Administrative Agent, for the account of the Lenders or (as the case may be) the
Administrative Agent, on the date on which such amount is due and payable
hereunder or under such other Loan Document, such additional amount in Dollars
as shall be necessary to enable the Lenders to receive the same net amount which
the Lenders would have received on such due date had no such obligation been
imposed upon the Borrower. The Borrower will deliver promptly to the
Administrative Agent certificates or other valid vouchers for all taxes or other
charges deducted from or paid with respect to payments made by the Borrower
hereunder or under such other Loan Document.

     Section 4.2.   COMPUTATIONS. All computations of interest on the Loans and
of other fees to the extent applicable shall be based on a 360-day year and paid
for the actual number of days elapsed. Except as otherwise provided in the
definition of the term "INTEREST PERIOD" with respect to LIBOR Rate Loans,

<Page>

                                      -54-

whenever a payment hereunder or under any of the other Loan Documents becomes
due on a day that is not a Business Day, the due date for such payment shall be
extended to the next succeeding Business Day, and interest shall accrue during
such extension. The outstanding amount of the Loans as reflected on the Note
Records from time to time shall constitute PRIMA FACIE evidence of the principal
amount thereof.

     Section 4.3.   INABILITY TO DETERMINE LIBOR RATE. In the event, prior to
the commencement of any Interest Period relating to any LIBOR Rate Loan, the
Administrative Agent shall reasonably determine that adequate and reasonable
methods do not exist for ascertaining the LIBOR Rate that would otherwise
determine the rate of interest to be applicable to any LIBOR Rate Loan during
any Interest Period, the Administrative Agent shall forthwith give notice of
such determination (which shall be conclusive and binding on the Borrower) to
the Borrower and the Lenders. In such event (a) any Loan Request or Competitive
Bid Request with respect to LIBOR Rate Loans shall be automatically withdrawn
and shall be deemed a request for Alternate Base Rate Loans (in the case of
Revolving Credit Loans) or Absolute Competitive Bid Loans (in the case of
Competitive Bid Loans), (b) each Revolving Credit LIBOR Rate Loan will
automatically, on the last day of the then current Interest Period thereof,
become a Alternate Base Rate Loan, and (c) the obligations of the Lenders to
make LIBOR Rate Loans shall be suspended until the Administrative Agent
reasonably determines that the circumstances giving rise to such suspension no
longer exist, whereupon the Administrative Agent shall so notify the Borrower
and the Lenders.

     Section 4.4.   ILLEGALITY. Subject to Sections 4.11 and 4.12 hereof, but
notwithstanding any other provisions herein, if any present or future law,
regulation, treaty or directive or in the interpretation or application thereof
shall make it unlawful for any Lender to make or maintain LIBOR Rate Loans, such
Lender shall forthwith give notice of such circumstances to the Borrower and the
other Lenders and thereupon (a) the commitment of such Lender to make LIBOR Rate
Loans or convert Alternate Base Rate Loans to LIBOR Rate Loans shall forthwith
be suspended and (b) such Lender's Commitment Percentage of Revolving Credit
LIBOR Rate Loans then outstanding shall be converted automatically to Alternate
Base Rate Loans on the last day of each Interest Period applicable to such LIBOR
Rate Loans or within such earlier period as may be required by law, all until
such time as it is no longer unlawful for such Lender to make or maintain LIBOR
Rate Loans. Subject to Sections 4.11 and 4.12 hereof, the Borrower hereby agrees
to promptly pay the Administrative Agent for the account of such Lender, upon
demand, any additional amounts necessary to compensate such Lender for any costs
incurred by such Lender in making any conversion required by this Section 4.4
prior to the last day of an Interest Period with respect to a LIBOR Rate Loan,
including any interest or fees payable by such

<Page>

                                      -55-

Lender to lenders of funds obtained by it in order to make or maintain its LIBOR
Rate Loans hereunder.

     Section 4.5.   ADDITIONAL COSTS, ETC. Subject to Sections 4.11 and 4.12
hereof, if any present or future applicable law, which expression, as used
herein, includes statutes, rules and regulations thereunder and interpretations
thereof by any competent court or by any governmental or other regulatory body
or official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Lender or the Administrative
Agent by any central bank or other fiscal, monetary or other authority (whether
or not having the force of law), shall:

          (a) subject any Lender or the Administrative Agent to any tax, levy,
impost, duty, charge, fee, deduction or withholding of any nature with respect
to this Agreement, the other Loan Documents, any Letters of Credit, such
Lender's Commitment or the Loans (other than taxes based upon or measured by the
income or profits of such Lender or the Administrative Agent), or

          (b) materially change the basis of taxation (except for changes in
taxes on income or profits) of payments to any Lender of the principal of or the
interest on any Loans or any other amounts payable to the Administrative Agent
or any Lender under this Agreement or the other Loan Documents, or

          (c) impose or increase or render applicable (other than to the extent
specifically provided for elsewhere in this Agreement) any special deposit,
reserve, assessment, liquidity, capital adequacy or other similar requirements
(whether or not having the force of law) against assets held by, or deposits in
or for the account of, or loans by, or letters of credit issued by, or
commitments of an office of any Lender, or

          (d) impose on any Lender or the Administrative Agent any other
conditions or requirements with respect to this Agreement, the other Loan
Documents, any Letters of Credit, the Loans, such Lender's Commitment, or any
class of loans, letters of credit or commitments of which any of the Loans or
such Lender's Commitment forms a part;

and the result of any of the foregoing is

              (i)   to increase the cost to any Lender of making, funding,
          issuing, renewing, extending or maintaining any of the Loans or such
          Lender's Commitment or any Letter of Credit, or

<Page>

                                      -56-

              (ii)  to reduce the amount of principal, interest,
          Reimbursement Obligation or other amount payable to such Lender or the
          Administrative Agent hereunder on account of such Lender's Commitment,
          any Letter of Credit or any of the Loans, or

              (iii) to require such Lender or the Administrative Agent to
          make any payment or to forego any interest or Reimbursement Obligation
          or other sum payable hereunder, the amount of which payment or
          foregone interest or Reimbursement Obligation or other sum is
          calculated by reference to the gross amount of any sum receivable or
          deemed received by such Lender or the Administrative Agent from the
          Borrower hereunder,

then; and in each such case arising or occurring in the immediately preceding
365 days from such demand, the Borrower will, within thirty (30) days after
demand made by such Lender or (as the case may be) the Administrative Agent at
any time and from time to time and as often as the occasion therefor may arise,
within the shorter of such maximum allowable period as permitted by law or such
Lender's internal policies (but no longer than one year or the occurrence of the
Maturity Date, if sooner) pay to such Lender such additional amounts as such
Lender shall determine in good faith to be sufficient to compensate such Lender
for such additional cost, reduction, payment or foregone interest or other sum,
PROVIDED that such Lender is generally imposing similar charges on its other
similarly situated borrowers.

     Section 4.6.   CAPITAL ADEQUACY. Subject to Sections 4.11 and 4.12 hereof,
if after the date hereof any Lender or the Administrative Agent determines in
good faith that (i) the adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by a court or governmental
authority with appropriate jurisdiction, or (ii) compliance by such Lender or
the Administrative Agent or any Person controlling such Lender or the
Administrative Agent with any law, governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law) of any such
Person regarding capital adequacy, has the effect of reducing the return on such
Lender's or the Administrative Agent's Commitment with respect to any Loans to a
level below that which such Lender or the Administrative Agent could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or the Administrative Agent's then existing policies with respect
to capital adequacy and assuming full utilization of such entity's capital) by
any amount deemed by such Lender or (as the case may be) the Administrative
Agent to be material, then such Lender or the Administrative Agent may notify
the Borrower of such fact. To the extent that the amount of such reduction in
the return on capital is

<Page>

                                      -57-

not reflected in the Alternate Base Rate, the Borrower agrees to pay such Lender
or (as the case may be) the Administrative Agent the amount of such reduction in
the return on capital as and when such reduction is determined, within thirty
(30) days after presentation by such Lender or (as the case may be) the
Administrative Agent of a certificate in accordance with Section 4.7 hereof
which certificate shall be presented within the shorter of such maximum
allowable period as permitted by law or such Lender's internal policies (but no
longer than one year or the occurrence of the Maturity Date, if sooner). Each
Lender shall allocate such cost increases among its customers in good faith and
on an equitable basis.

     Section 4.7.   CERTIFICATE. A certificate setting forth any additional
amounts payable pursuant to Sections 4.5 or 4.6 and a brief explanation of such
amounts which are due, submitted by any Lender or the Administrative Agent to
the Borrower shall be PRIMA FACIE evidence that such amounts are due and owing.

     Section 4.8.   INDEMNITY. In addition to the other provisions of this
Agreement regarding such matters, the Borrower agrees to indemnify the
Administrative Agent and each Lender and to hold the Administrative Agent and
each Lender harmless from and against any loss, cost or expense (including LIBOR
Breakage Costs, but excluding any loss of Applicable Margin on the relevant
Loans) that the Administrative Agent or such Lender may sustain or incur as a
consequence of (a) the failure by the Borrower to pay any principal amount of or
any interest on any LIBOR Rate Loans as and when due and payable, including any
such loss or expense arising from interest or fees payable by the Administrative
Agent or such Lender to lenders of funds obtained by it in order to maintain its
LIBOR Rate Loans, (b) the failure by the Borrower to make a borrowing or
conversion after the Borrower has given or is deemed pursuant to Section 2.6(c)
to have given a Completed Revolving Credit Loan Request or Competitive Bid
Request for a LIBOR Rate Loan or a Conversion Request to convert a Alternate
Base Rate Loan into a LIBOR Rate Loan, and (c) the making of any payment of a
LIBOR Rate Loan or the making of any conversion of any such Loan to a Alternate
Base Rate Loan on a day that is not the last day of the applicable Interest
Period with respect thereto, including interest or fees payable by the
Administrative Agent or a Lender to lenders of funds obtained by it in order to
maintain any such LIBOR Rate Loans.

     Section 4.9.   INTEREST DURING EVENT OF DEFAULT. During the continuance of
an Event of Default, outstanding principal and (to the extent permitted by
applicable law) interest on the Loans and all other amounts payable hereunder or
under any of the other Loan Documents shall bear interest at a rate per annum
equal to four percent (4%) above the rate otherwise then in effect until such
amount shall be paid in full (after as well as before judgment).

<Page>

                                      -58-

     Section 4.10.  [Intentionally Omitted]

     Section 4.11.  REASONABLE EFFORTS TO MITIGATE. Each Lender agrees that as
promptly as practicable after it becomes aware of the occurrence of an event or
the existence of a condition that would cause it to be affected under Sections
4.4, 4.5 or 4.6, such Lender will give notice thereof to the Borrower, with a
copy to the Administrative Agent and, to the extent so requested by the Borrower
and not inconsistent with regulatory policies applicable to such Lender, such
Lender shall use reasonable efforts and take such actions as are reasonably
appropriate (including the changing of its lending office or branch) if as a
result thereof the additional moneys which would otherwise be required to be
paid to such Lender pursuant to such sections would be reduced other than for de
minimis amounts, or the illegality or other adverse circumstances which would
otherwise require a conversion of such Loans or result in the inability to make
such Loans pursuant to such sections would cease to exist, and in each case if,
as determined by such Lender in its sole discretion, the taking such actions
would not adversely affect such Loans.

     Section 4.12.  REPLACEMENT OF LENDERS. If any Lender (an "AFFECTED LENDER")
(i) makes demand upon the Borrower for (or if the Borrower is otherwise required
to pay) amounts pursuant to Sections 4.4, 4.5 or 4.6, or (ii) is unable to make
or maintain LIBOR Rate Loans as a result of a condition described in Section
4.4, the Borrower may, within 90 days of receipt of such demand, notice (or the
occurrence of such other event causing the Borrower to be required to pay such
compensation or causing Section 4.4 to be applicable) as the case may be, by
notice (a "REPLACEMENT NOTICE") in writing to the Administrative Agent and such
Affected Lender (A) request the Affected Lender to cooperate with the Borrower
in obtaining a replacement lender satisfactory to the Administrative Agent and
the Borrower (the "REPLACEMENT LENDER"); (B) request the non-Affected Lenders to
acquire and assume all of the Affected Lender's Loans and Commitment, and/or
participate in Letters of Credit, as provided herein, but none of such Lenders
shall be under an obligation to do so; or (C) designate a Replacement Lender
which is an Eligible Assignee and is reasonably satisfactory to the
Administrative Agent other than when an Event of Default has occurred and is
continuing and absolutely satisfactory to the Administrative Agent when an Event
of Default has occurred and is continuing. If any satisfactory Replacement
Lender shall be obtained, and/or any of the non-Affected Lenders shall agree to
acquire and assume all of the Affected Lender's Loans and Commitment, and/or
participate in Letters of Credit, then such Affected Lender shall assign, in
accordance with Section 18, all of its Commitment, Loans, Notes and other rights
and obligations under this Agreement and all other Loan Documents to such
Replacement Lender or non-Affected Lenders, as the case may be, in exchange for
payment of the principal amount so assigned and all interest and fees accrued on
the amount so assigned, plus all other

<Page>

                                      -59-

Obligations then due and payable to the Affected Lender; PROVIDED, HOWEVER, that
(x) such assignment shall be in accordance with the provisions of Section 18,
shall be without recourse, representation or warranty and shall be on terms and
conditions reasonably satisfactory to such Affected Lender and such Replacement
Lender and/or non-Affected Lenders, as the case may be, and (y) prior to any
such assignment, the Borrower shall have paid to such Affected Lender all
amounts properly demanded and unreimbursed under Sections 4.4, 4.5 and 4.8.

     Section 5.     GUARANTIES.

     Section 5.1.   GUARANTIES. Each of the Guarantors will jointly and
severally guaranty all of the Obligations pursuant to its Guaranty. The
Obligations are full recourse obligations of the Borrower and each Guarantor,
and all of the respective assets and properties of the Borrower and each such
Guarantor shall be available for the payment in full in cash and performance of
the Obligations (subject to Permitted Liens and senior claims enforceable as
senior in accordance with applicable law, without the Lenders hereby agreeing to
any such senior claim that is otherwise prohibited by this Agreement). Other
than during the continuance of a Default or Event of Default, at the request of
the Borrower, the Guaranty of any Subsidiary Guarantor shall be released by the
Administrative Agent if and when all of the Real Estate owned or ground-leased
by such Subsidiary Guarantor shall cease (not thereby creating a Default or
Event of Default) to be owned by such Subsidiary Guarantor or by any other
Borrower, Guarantor, Subsidiary or other Affiliate of any of same, PROVIDED the
foregoing shall never permit the release of MCRC.

     Section 5.2.   SUBSIDIARY GUARANTY PROCEEDS. (a) Notwithstanding any
provision of this Agreement or any other Loan Document to the contrary, the
Administrative Agent and the Lenders agree with the Borrower that any funds,
claims, or distributions actually received by the Administrative Agent or any
Lender for the account of any Lender as a result of the enforcement of, or
pursuant to a claim relating solely to the Loans under, any Subsidiary Guaranty,
net of the Administrative Agent's and the Lenders' expenses of collection
thereof (such net amount, "SUBSIDIARY GUARANTY PROCEEDS"), shall be made
available for distribution equally and ratably (in proportion of the aggregate
amount of principal, interest and other amounts then owed in respect of the
Obligations or of the issuance of Public Debt, as the case may be) among the
Administrative Agent, the Lenders and the trustee or trustees of any Public Debt
so long as the Administrative Agent receives written notice of the amounts then
owed under the Public Debt; PROVIDED that such agreement to distribute
Subsidiary Guaranty Proceeds shall not be effective if the holders of the Public
Debt have the benefit of guaranties at any time from the Subsidiaries of the

<Page>

                                      -60-

Borrower and have not made a reciprocal agreement to share the proceeds of such
guaranties with the Lenders. The Administrative Agent is hereby authorized, by
the Borrower, by each Lender and by the Borrower on behalf of each Subsidiary
Guarantor to make such Subsidiary Guaranty Proceeds available pursuant to the
immediately preceding sentence. No Lender shall have any interest in any amount
paid over by the Administrative Agent or any other Lender to the trustee or
trustees in respect of any Public Debt (or to the holders thereof) pursuant to
the foregoing authorization. This Section 5.2 shall apply solely to Subsidiary
Guaranty Proceeds, and not to any payments, funds, claims or distributions
received by the Administrative Agent or any Lender directly or indirectly from
Borrower or any other Person (including a Subsidiary Guarantor) other than from
a Subsidiary Guarantor pursuant to the enforcement of, or the making of a claim
relating solely to the Loans under, a Subsidiary Guaranty. The Borrower is aware
of the terms of the Subsidiary Guarantees, and specifically understands and
agrees with the Administrative Agent, and the Lenders that, to the extent
Subsidiary Guaranty Proceeds are distributed to holders of Public Debt or their
respective trustees, such Subsidiary Guarantor has agreed that the Obligations
under this Agreement and any other Loan Document will not be deemed reduced by
any such distributions, and each Subsidiary Guarantor shall continue to make
payments pursuant to its Subsidiary Guaranty until such time as the Obligations
have been paid in full (and the Commitments have been terminated and any Letter
of Credit Participations reduced to zero).

          (b) Nothing contained in this Section 5.2 shall be deemed (i) to
limit, modify, or alter the rights of the Administrative Agent or any of the
Lenders under any Subsidiary Guaranty or other Guaranty, (ii) to subordinate the
Obligations to any Public Debt, or (iii) to give any holder of Public Debt (or
any trustee for such holder) any rights of subrogation.

          (c) This Section 5.2, and each Guaranty, are for the sole benefit of
the Administrative Agent, the Lenders and their respective successors and
assigns. Nothing contained herein or in any Guaranty shall be deemed for the
benefit of any holder of Public Debt, or any trustee for such holder, nor shall
anything contained herein or therein be construed to impose on the
Administrative Agent or any Lender any fiduciary duties, obligations or
responsibilities to the holders of any Public Debt or their trustees (including,
but not limited to, any duty to pursue any Guarantor for payment under its
Subsidiary Guaranty).

     Section 6.     REPRESENTATIONS AND WARRANTIES. The Borrower for itself and
for each Guarantor insofar as any such statements relate to such Guarantor
represents and warrants to the Administrative Agent and the Lenders all of the
statements contained in this Section 6.

              other jurisdiction would not have a materially adverse effect on
              the

              similar, as applicable, to (a) (i) or (ii) above shall be included
              in each such subsequent Guarantor's Subsidiary Guaranty, and the
              Borrower shall be deemed to make for itself and on behalf of each

              Subsidiaries. Except as disclosed in SCHEDULE 6.1(b), no shares
              of, or equity interests in, any of MCRC's Subsidiaries held by
              MCRC are subject to any restrictions on transfer pursuant to any
              of MCRC's Subsidiaries' applicable partnership, charter, by-laws
              or any shareholder agreements, voting agreements, voting trusts,

investigations of any kind pending or, to the knowledge of the Borrower and the
Guarantors, threatened against the Borrower, any Guarantor or any of their
respective Subsidiaries before any court, tribunal or administrative agency or

individually or in the aggregate, to have a Material Adverse Effect or
materially impair the rights of the Borrower or such Guarantor to carry on their
respective businesses substantially as now conducted by them, or result in any
substantial liability not adequately covered by insurance, or for which adequate
reserves are not maintained, as reflected in the applicable financial statements
of MCRLP and MCRC, or which question the validity of this Agreement or any of
the other Loan Documents, or any action taken or to be taken pursuant hereto or

respective Subsidiaries) are bound or any decree, order, judgment, statute,
license, rule or regulation, in any of the foregoing cases in a manner that

imposition of substantial penalties or have a Material Adverse Effect.

     Section 6.10.  TAX STATUS.

          (a) (i) Each of the Borrower, the Guarantors and their respective

basis for any such claim.

<Page>

                                      -68-

otherwise encumbered or transferred any of their respective interests in any
Subsidiary (including in the case of MCRC, its interests in MCRLP, and in the
case of the Borrower, its interests in the Operating Subsidiaries) or in any
Partially-Owned Entity.

     Section 6.14.  ABSENCE OF LIENS The Borrower or a Guarantor is the owner of

or for transactions that have been determined by the Board of Directors of the
relevant Borrower, Guarantor or Subsidiary (or its respective general partner)

party to any transaction with the Borrower, any Guarantor or any of their
respective Subsidiaries (other than for or in connection with services as
employees, officers and directors), including any contract, agreement or other
arrangement providing for the furnishing of services to or by, providing for
rental of real or personal property to or from, or otherwise requiring payments
to or from any officer, partner, director or such employee or, to the knowledge
of the Borrower, any corporation, partnership, trust or other entity in which
any officer, partner, director, or any such employee or natural Person related
to such officer, partner, director or employee or other Person in which such
officer, partner, director or employee has a direct or indirect beneficial
interest has a substantial interest or is an officer, director, trustee or
partner.

     Section 6.16.  EMPLOYEE BENEFIT PLANS.

          Section 6.16.1 IN GENERAL. Each Employee Benefit Plan and each
     Guaranteed Pension Plan has been maintained and operated in compliance in
     all material respects with the provisions of ERISA and, to the extent
     applicable, the Code, including but not limited to the provisions
     thereunder respecting prohibited transactions and the bonding of
     fiduciaries and other persons handling plan funds as required by Section
     412 of ERISA. The Borrower has heretofore delivered to the Administrative
     Agent the most recently completed annual report, Form 5500, with all
     required attachments, and actuarial statement required to be submitted
     under Section 103(d) of ERISA, with respect to each Guaranteed Pension
     Plan.

          Section 6.16.2 TERMINABILITY OF WELFARE PLANS. No Employee Benefit
     Plan, which is an employee welfare benefit plan within the meaning of
     Section 3(1) or Section 3(2)(B) of ERISA, provides benefit coverage
     subsequent to termination of

<Page>

                                      -69-

employment, except as required by Title I, Part 6 of ERISA or the applicable
state insurance laws. The Borrower may terminate each such Plan at any time (or
at any time subsequent to the expiration of any applicable bargaining agreement)
in the discretion of the Borrower without material liability to any Person other
than for claims arising prior to termination.

     Section 6.16.3 GUARANTEED PENSION PLANS. Each contribution required to be
made to a Guaranteed Pension Plan, whether required to be made to avoid the
incurrence of an accumulated funding deficiency, the notice or lien provisions
of Section 302(f) of ERISA, or otherwise, has been timely made. No waiver of an
accumulated funding deficiency or extension of amortization periods has been
received with respect to any Guaranteed Pension Plan, and neither the Borrower
nor any Guarantor nor any ERISA Affiliate is obligated to or has posted security
in connection with an amendment to a Guaranteed Pension Plan pursuant to Section
307 of ERISA or Section 401(a)(29) of the Code. No liability to the PBGC (other
than required insurance premiums, all of which have been paid) has been incurred
by the Borrower nor any Guarantor nor any ERISA Affiliate with respect to any
Guaranteed Pension Plan and there has not been any ERISA Reportable Event (other
than an ERISA Reportable Event as to which the requirement of 30 days notice has
been waived), or any other event or condition which presents a material risk of
termination of any Guaranteed Pension Plan by the PBGC. Based on the latest
valuation of each Guaranteed Pension Plan (which in each case occurred within
twelve months of the date of this representation), and on the actuarial methods
and assumptions employed for that valuation, the aggregate benefit liabilities
of all such Guaranteed Pension Plans within the meaning of Section 4001 of ERISA
did not exceed the aggregate value of the assets of all such Guaranteed Pension
Plans, disregarding for this purpose the benefit liabilities and assets of any
Guaranteed Pension Plan with assets in excess of benefit liabilities, by more
than $500,000.

     Section 6.16.4 MULTIEMPLOYER PLANS. Neither the Borrower nor any Guarantor
nor any ERISA Affiliate has incurred any material liability (including secondary
liability) to any Multiemployer Plan as a result of a complete or partial
withdrawal from such Multiemployer Plan under Section 4201 of ERISA or as a
result of a sale of assets described in Section 4204 of ERISA. Neither the
Borrower nor any ERISA Affiliate has been notified that any Multiemployer Plan
is in reorganization or insolvent under and within the meaning of Section 4241
or Section 4245 of ERISA or is at material risk of entering reorganization or
becoming insolvent, or that any Multiemployer Plan intends to terminate or has
been terminated under Section 4041A of ERISA.

     Section 6.17.  REGULATIONS U AND X. The proceeds of the Loans shall be used
for the purposes described in Section 7.12. No portion of any Loan is to be
used, and no portion of any Letter of Credit is to be obtained, for the purpose
of purchasing or carrying any "margin security" or "margin stock" as such terms
are used in Regulations U and X of the Board of Governors of the Federal Reserve
System, 12 C.F.R. Parts 221 and 224, PROVIDED the Borrower may purchase MCRC
stock as long as it does not at any time cause the Lenders to be in violation of
Regulations U and X and such action does not otherwise constitute a Default or
an Event of Default.

     Section 6.18.  ENVIRONMENTAL COMPLIANCE. The Borrower has caused
environmental assessments to be conducted and/or taken other steps to
investigate the past and present environmental condition and usage of the Real
Estate and the operations conducted thereon. Except as disclosed in the
environmental assessments provided to the Administrative Agent pursuant to
Section 10.7 and based upon such assessments and/or investigation, to the
Borrower's knowledge, the Borrower has determined that:

          (a)  None of the Borrower, any Guarantor, any of their respective
Subsidiaries or any operator of the Real Estate or any portion thereof, or any
operations thereon is in violation, or alleged violation (in writing), of any
judgment, order, law, license, rule or regulation pertaining to environmental
matters, including without limitation, those arising under the Resource
Conservation and Recovery Act ("RCRA"), the Comprehensive Environmental
Response, Compensation and Liability Act of 1980 as amended ("CERCLA"), the
Superfund Amendments and Reauthorization Act of 1986 ("SARA"), the Federal Clean
Water Act, the Federal Clean Air Act, the Toxic Substances Control Act, or any
state or local statute, regulation, ordinance or order relating to health,
safety or the environment (hereinafter "ENVIRONMENTAL LAWS"), which violation or
alleged violation (in writing) has, or its remediation would have, by itself or
when aggregated with all such other violations or alleged violations, a Material
Adverse Effect or constitutes a Disqualifying Environmental Event.

          (b)  None of the Borrower, any Guarantor or any of their respective
Subsidiaries has received notice from any third party, including, without
limitation, any federal, state or local governmental authority, (i) that it has
been identified by the United States Environmental Protection Agency ("EPA") as
a potentially responsible party under CERCLA with respect to a site listed on
the National Priorities List, 40 C.F.R. Part 300 Appendix B (1986), (ii) that
any hazardous waste, as defined by 42 U.S.C. Section 6903(5), any hazardous
substances as defined by 42 U.S.C. Section 9601(14), any pollutant or
contaminant as defined by 42 U.S.C. Section 9601(33) or any toxic substances,
oil or hazardous materials or other chemicals or substances regulated by any
Environmental

                                      -71-

Laws ("HAZARDOUS SUBSTANCES") which it has generated, transported or disposed of
has been found at any site at which a federal, state or local agency or other
third party has conducted or has ordered that the Borrower, any Guarantor or any
of their respective Subsidiaries conduct a remedial investigation, removal or
other response action pursuant to any Environmental Law, or (iii) that it is or
shall be a named party to any claim, action, cause of action, complaint, or
legal or administrative proceeding (in each case, contingent or otherwise)
arising out of any third party's incurrence of costs, expenses, losses or
damages of any kind whatsoever in connection with the release of Hazardous
Substances; which event described in any such notice would have a Material
Adverse Effect or constitutes a Disqualifying Environmental Event.

          (c)  (i) No portion of the Real Estate has been used for the handling,
processing, storage or disposal of Hazardous Substances except in accordance
with applicable Environmental Laws; and no underground tank or other underground

or any Partially-Owned Entity may be liable or for which a lien may be imposed
on any Real Estate; provided any of which events described in clauses (i)
through (iv) above would have a Material Adverse Effect or constitute a
Disqualifying Environmental Event with respect to any Unencumbered Property.

cause each Guarantor and each Guarantor's Subsidiaries to, and the Borrower will

Guarantor or any of their respective Subsidiaries that could reasonably be

from discontinuing the operation and maintenance of any of its properties or any
of those of its Subsidiaries if such discontinuance is, in the judgment of the
Borrower, desirable in the conduct of its or their business and such

properties and those of its Subsidiaries used or useful in the conduct of its
business or the business of its Subsidiaries to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment,
ordinary wear and tear excepted, (b) to cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of MCRC may be necessary so that the business carried on in connection
therewith may be properly conducted at all times, and (c) to cause each of its
Subsidiaries to continue to engage primarily in the businesses now conducted by
it and in related businesses, consistent with the requirements of the fourth
sentence of this Section 7.7; PROVIDED that nothing in this Section 7.7 shall
prevent MCRC from discontinuing the operation and maintenance of any of its
properties or any of those of its Subsidiaries if such discontinuance is, in the
judgment of MCRC, desirable in the conduct of its or their business and such
discontinuance does not cause a Default or an Event of Default hereunder and
does not in the aggregate materially adversely affect the business of MCRC and
its Subsidiaries on a consolidated basis.

operations and real estate portfolios in similar geographic areas and in
amounts, containing such terms, in such forms and for such periods as may be
reasonable and prudent for such businesses.

     Section 7.9.   TAXES. The Borrower will, and will cause each Guarantor to,
pay or cause to be paid real estate taxes, other taxes, assessments and other
governmental charges against the Real Estate before the same become delinquent
and will duly pay and discharge, or cause to be paid and discharged, before the
same shall become overdue, all taxes, assessments and other governmental charges
imposed upon its sales and activities, or any part thereof, or upon the income
or profits therefrom, as well as all claims for labor, materials, or supplies
that if unpaid might by law become a lien or charge upon any of the Real Estate;

appropriate proceedings and if the Borrower or such Guarantor shall have set
aside on its books adequate reserves with respect thereto; and PROVIDED FURTHER

charges, levies or claims forthwith upon the commencement of proceedings to

<Page>

                                      -81-

an Event of Default if such breach results in an aggregate amount in excess of

jurisdiction for which payment is required to be made and has not been timely
made.

     Section 7.10.  INSPECTION OF PROPERTIES AND BOOKS. The Borrower will, and
will cause each Guarantor to, permit the Lenders, coordinated through the
Administrative Agent, (a) on an annual basis as a group, or more frequently if

Event of Default shall have occurred and be continuing, to visit and inspect any
of the properties of the Borrower, any Guarantor or any of their respective
Subsidiaries, and to examine the books of account of the Borrower, the
Guarantors and their respective Subsidiaries (and to make copies thereof and
extracts therefrom) and (b) to discuss the affairs, finances and accounts of the
Borrower, the Guarantors and their respective Subsidiaries with, and to be
advised as to the same by, its officers, all at such reasonable times and
intervals during normal business hours as the Administrative Agent may

Default; and PROVIDED FURTHER that such Person has executed a confidentiality
agreement in substantially the form previously executed by the Administrative
Agent. The Administrative Agent and each Lender agrees to treat any non-public

validity or amount thereof shall currently be contested in good faith by
appropriate proceedings and if the Borrower or such Guarantor shall have set
aside on its books adequate reserves with respect thereto; and PROVIDED FURTHER

solely for general working capital needs (including letters of credit) and other
general corporate purposes.

     Section 7.13.  ACQUISITION OF UNENCUMBERED PROPERTIES. The Borrower shall
promptly, but in any event within thirty (30) days of the acquisition of an
Unencumbered Property or the qualification of any Real Estate as an Unencumbered
Property, deliver to the Administrative Agent a copy of the Title Policy or
commitment for a Title Policy and the final environmental site assessment for
such Unencumbered Property.

     Section 7.14.  ADDITIONAL GUARANTORS; SOLVENCY OF GUARANTORS.

          (a)  If, after the Closing Date, a Subsidiary that is not a Guarantor,
(i) acquires any Real Estate that then or thereafter qualifies under (a)-(d) of
the definition of Unencumbered Property and is wholly-owned or ground leased
under an Eligible Ground Lease, or (ii) extends, holds or acquires any
Intercompany Secured Debt, in each case the Borrower shall cause such Person
(which Person must be or become a wholly-owned Subsidiary) to execute and
deliver a Guaranty to the Administrative Agent and the Lenders in substantially
the form of EXHIBIT B hereto. Such Guaranty shall evidence consideration and
equivalent value. The Borrower will not permit any Guarantor that owns or ground
leases any Unencumbered Properties to have any Subsidiaries unless such
Subsidiary's business, obligations and undertakings are exclusively related to
the business of such Guarantor in the ownership of the Unencumbered Properties.

          (b)  The Borrower, MCRC, and each Subsidiary Guarantor is solvent,
other than for Permitted Event(s) permitted by this Agreement which shall be the
only Non-Material Breaches under this Section 7.14(b). The Borrower and MCRC
each acknowledge that, subject to the indefeasible payment and performance in
full of the Obligations, the rights of contribution among each of the them and
the Subsidiary Guarantors are in accordance with applicable laws and in
accordance with each such Person's benefits under the Loans and this Agreement.
The Borrower further acknowledges that, subject to the indefeasible payment and
performance in full of the Obligations, the rights of subrogation of the
Subsidiary Guarantors as against the Borrower and MCRC are in accordance with
applicable laws.

     Section 7.15.  FURTHER ASSURANCES. The Borrower will, and will cause each
Guarantor to, cooperate with, and to cause each of its Subsidiaries to cooperate
with, the Administrative Agent and the Lenders and execute such further

<Page>

                                      -83-

instruments and documents as the Lenders or the Administrative Agent shall
reasonably request to carry out to their reasonable satisfaction the
transactions contemplated by this Agreement and the other Loan Documents.

     Section 7.16.  [Intentionally Omitted]

     Section 7.17.  ENVIRONMENTAL INDEMNIFICATION. The Borrower covenants and
agrees that it and its Subsidiaries will indemnify and hold the Administrative
Agent and each Lender, and each of their respective Affiliates, harmless from
and against any and all claims, expense, damage, loss or liability incurred by
the Administrative Agent or any Lender (including all reasonable costs of legal
representation incurred by the Administrative Agent or any Lender in connection
with any investigative, administrative or judicial proceeding, whether or not
the Administrative Agent or any Lender is party thereto, but excluding, as
applicable for the Administrative Agent or a Lender, any claim, expense, damage,
loss or liability as a result of the gross negligence or willful misconduct of
the Administrative Agent or such Lender or any of their respective Affiliates)
relating to (a) any Release or threatened Release of Hazardous Substances on any
Real Estate; (b) any violation of any Environmental Laws with respect to
conditions at any Real Estate or the operations conducted thereon; (c) the
investigation or remediation of off-site locations at which the Borrower, any
Guarantor or any of their respective Subsidiaries or their predecessors are
alleged to have directly or indirectly disposed of Hazardous Substances; or (d)
any action, suit, proceeding or investigation brought or threatened with respect
to any Hazardous Substances relating to Real Estate (including, but not limited
to, claims with respect to wrongful death, personal injury or damage to
property). In litigation, or the preparation therefor, the Lenders and the
Administrative Agent shall be entitled to select their own counsel and
participate in the defense and investigation of such claim, action or
proceeding, and the Borrower shall bear the expense of such separate counsel of
the Administrative Agent and the Lenders if (i) in the written opinion of
counsel to the Administrative Agent and the Lenders, use of counsel of the
Borrower's choice could reasonably be expected to give rise to a conflict of
interest, (ii) the Borrower shall not have employed counsel reasonably
satisfactory to the Administrative Agent and the Lenders within a reasonable
time after notice of the institution of any such litigation or proceeding, or
(iii) the Borrower authorizes the Administrative Agent and the Lenders to employ
separate counsel at the Borrower's expense. It is expressly acknowledged by the
Borrower that this covenant of indemnification shall survive the payment of the
Loans and shall inure to the benefit of the Administrative Agent and the Lenders
and their respective Affiliates, their respective successors, and their
respective assigns under the Loan Documents permitted under this Agreement.

     Section 7.18.  RESPONSE ACTIONS. The Borrower covenants and agrees that
if any Release or disposal of Hazardous Substances shall occur or shall have
occurred on any Real Estate owned by it or any of its Subsidiaries, the Borrower
will cause the prompt containment and removal of such Hazardous Substances and
remediation of such Real Estate if necessary to comply with all Environmental
Laws.

     Section 7.19.  ENVIRONMENTAL ASSESSMENTS. If the Majority Lenders have
reasonable grounds to believe that a Disqualifying Environmental Event has
occurred with respect to any Unencumbered Property, after reasonable notice by
the Administrative Agent, whether or not a Default or an Event of Default shall
have occurred, the Majority Lenders may determine that the affected Real Estate
no longer qualifies as an Unencumbered Property; PROVIDED that prior to making
such determination, the Administrative Agent shall give the Borrower reasonable
notice and the opportunity to obtain one or more environmental assessments or
audits of such Unencumbered Property prepared by a hydrogeologist, an
independent engineer or other qualified consultant or expert approved by the
Administrative Agent, which approval will not be unreasonably withheld, to
evaluate or confirm (i) whether any Release of Hazardous Substances has occurred
in the soil or water at such Unencumbered Property and (ii) whether the use and
operation of such Unencumbered Property materially complies with all
Environmental Laws (including not being subject to a matter that is a
Disqualifying Environmental Event). Such assessment will then be used by the
Administrative Agent to determine whether a Disqualifying Environmental Event
has in fact occurred with respect to such Unencumbered Property. All such
environmental assessments shall be at the sole cost and expense of the Borrower.

     Section 7.20.  EMPLOYEE BENEFIT PLANS.

          (a)  IN GENERAL. Each Employee Benefit Plan maintained by the
Borrower, any Guarantor or any of their respective ERISA Affiliates will be
operated in compliance in all material respects with the provisions of ERISA
and, to the extent applicable, the Code, including but not limited to the
provisions thereunder respecting prohibited transactions.

          (b)  TERMINABILITY OF WELFARE PLANS. With respect to each Employee
Benefit Plan maintained by the Borrower, any Guarantor or any of their
respective ERISA Affiliates which is an employee welfare benefit plan within the
meaning of Section 3(1) or Section 3(2)(B) of ERISA, the Borrower, such
Guarantor, or any of their respective ERISA Affiliates, as the case may be, has
the right to terminate each such plan at any time (or at any time subsequent to
the expiration of any applicable bargaining agreement) without material
liability other than liability to pay claims incurred prior to the date of
termination.

          (c)  UNFUNDED OR UNDERFUNDED LIABILITIES. The Borrower will not, and
will not permit any Guarantor to, at any time, have accruing or accrued unfunded
or underfunded liabilities with respect to any Employee Benefit Plan, Guaranteed
Pension Plan or Multiemployer Plan, or permit any condition to exist under any
Multiemployer Plan that would create a withdrawal liability.

     Section 7.21.  NO AMENDMENTS TO CERTAIN DOCUMENTS. The Borrower will not,
and will not permit any Guarantor to, at any time cause or permit its
certificate of limited partnership, agreement of limited partnership, articles
of incorporation, by-laws, certificate of formation, operating agreement or
other charter documents, as the case may be, to be modified, amended or
supplemented in any respect whatever, without (in each case) the express prior
written consent or approval of the Administrative Agent, if such changes would
adversely affect MCRC's REIT status or otherwise materially adversely affect the
rights of the Administrative Agent and the Lenders hereunder or under any other
Loan Document.

     Section 7.22.  [Intentionally Omitted]

partner and management of MCRLP); PROVIDED, HOWEVER, if at least three (3) of

Majority Lenders to such position(s) such that, after such appointment, such
acceptable replacement individuals, together with the Key Management Individuals

Mitchell E. Hersh, Timothy M. Jones, Barry Lefkowitz, Roger W. Thomas and
Michael A. Grossman, and such replacement individuals as are reasonably

transfers of cash and cash equivalents upstream to MCRLP and MCRC, and shall
continue to follow such ordinary course of business. MCRLP shall not make net
transfers of cash and cash equivalents downstream to its and MCRC's Subsidiaries

granting or effect of such liens does not otherwise constitute a Default or
Event of Default), revenues or assets, whether now owned or hereafter acquired,

purposes of this clause, non-cash assets or interests in non-cash assets which
are distributed to equity interest holders of the Borrower shall be valued at
the value of such assets used in calculating Consolidated Total Capitalization)

                                      -93-

distributing Person is the subject of a Permitted Event; PROVIDED, HOWEVER, that
the Borrower may at all times make Distributions (after taking into account all
available funds of MCRC from all other sources) in the minimum aggregate amount
required in order to enable MCRC to continue to qualify as a REIT. In the event
that MCRC or MCRLP raises equity during the term of this Agreement, the
permitted percentage of Distributions will be adjusted based on the total
declared distribution per share and partnership units over the most recent four
(4) quarters to Funds From Operations per weighted average share and partnership
unit based on the most recent four (4) quarters.

     (b)  MCRC will not, during any period when any Event of Default has

Distributions required to be made by MCRC in order to maintain its status as a

liabilities (with the meaning of Section 4001 of ERISA) of all Guaranteed
Pension Plans exceeding the value of the aggregate assets of such Plans,
disregarding for this purpose the benefit liabilities and assets of any such
Plan with assets in excess of benefit liabilities; PROVIDED that none of (a) -
(e) shall be an Event of Default under Section 12.1(c) if the prohibited matters

<Page>

                                      -96-

Administrative Agent within five (5) Business Days being deemed to be its

     Subsidiaries, the Guarantors and any other wholly-owned Subsidiary
     (excluding any such Indebtedness or liabilities owed to the Borrower or any
     Guarantor; PROVIDED that, as to MCRC, MCRC has a corresponding Indebtedness
     or liability to the Borrower),

               (ii)   all Indebtedness or liabilities of each Partially-Owned
     Entity (including for Capitalized Leases), but only to the extent, if any,
     that said Indebtedness or liability is Recourse to the Borrower, the
     Guarantors or their respective Subsidiaries or any of their respective

<Page>

                                      -97-

     assets (other than their respective interests in such Partially-Owned
     Entity); PROVIDED that Recourse Indebtedness arising from such Person's
     acting as general partner or guarantor of collection only (and not of
     payment or performance) of a Partially-Owned Entity shall be limited to the
     amount by which the Indebtedness exceeds the liquidation value of the Real
     Estate and other assets owned by such Partially-Owned Entity if the
     creditor owed such Indebtedness is required by law or by contract to seek
     repayment of such Indebtedness from such Real Estate and other assets
     before seeking repayment from such Person, and

               (iii)  Indebtedness or liabilities of each Partially-Owned Entity
     to the extent of the pro-rata share of such Indebtedness or liability
     allocable to the Borrower, the Guarantors or their respective Subsidiaries
     without double counting.

          (b)  For purposes of Sections 9.1-9.8 hereof, Consolidated Adjusted
Net Income, Revised Consolidated Adjusted Net Income, Adjusted Unencumbered
Property NOI and Revised Adjusted Unencumbered Property NOI (and all defined
terms and calculations using such terms) shall be adjusted (i) to deduct the
actual results of any Real Estate disposed of by the Borrower, a Guarantor or
any of their respective Subsidiaries during the relevant fiscal period (for
Revised Consolidated Adjusted Net Income and Revised Adjusted Unencumbered
Property NOI only), (ii) to include the pro forma results of any Real Estate
acquired by the Borrower, a Guarantor or any of their respective Subsidiaries
during the relevant fiscal period, with such pro forma results being calculated
by (x) using the Borrower's pro forma projections for such acquired property,
subject to the Administrative Agent's reasonable approval, if such property has
been owned by the Borrower, a Guarantor or any of their respective Subsidiaries
for less than one complete fiscal quarter or (y) using the actual results for
such acquired property and adjusting such results for the appropriate period of
time required by the applicable financial covenant, if such property has been
owned by the Borrower, a Guarantor or any of their respective Subsidiaries for
at least one complete fiscal quarter (for Revised Consolidated Adjusted Net
Income and Revised Adjusted Unencumbered Property NOI only) and (iii) to the
extent applicable, to include the pro rata share of results attributable to the
Borrower from unconsolidated Subsidiaries of MCRC, the Borrower and their
respective Subsidiaries and from unconsolidated Partially-Owned Entities;
PROVIDED that income shall not be included until received without restriction in
cash by the Borrower.

          (c)  For purposes of Sections 9.1 - 9.8 hereof, together with each
other section of this Agreement that refers or relates to GAAP, if any change in
GAAP after the Financial Statement Date results in a change in the calculation
to be performed in any such section, solely as a result of such change in GAAP,
then

<Page>

                                      -98-

(i) the Borrower's compliance with such covenant(s) or section shall be
determined on the basis of GAAP in effect as of the Financial Statement Date,
and (ii) the Administrative Agent and the Borrower shall negotiate in good faith
a modification of any such covenant(s) or sections so that the economic effect
of the calculation of such covenant(s) or sections using GAAP as so changed is
as close as feasible to what the economic effect of the calculation of such
covenant(s) or sections would have been using GAAP in effect as of the Financial
Statement Date.

          (d)  For purposes of Sections 9.1-9.8 hereof, Consolidated Total
Capitalization and the Section 9.6 Sum (as such term is defined in Section 9.6
hereof) shall be adjusted (without double-counting) to include the Eligible Cash
1031 Proceeds from any Real Estate disposed of by the Borrower, a Guarantor or
any of their respective Subsidiaries and for which the results have been
deducted pursuant to Section 9.9(b).

or any of their respective Subsidiaries in this Agreement or any of the other

following occurs with respect to a Guaranteed Pension Plan: (i) an ERISA
Reportable Event, or a failure to make a required installment or other payment
(within the meaning of Section 302(f)(1) of ERISA), PROVIDED that the
Administrative Agent determines in its reasonable discretion that such event (A)
could be expected to result in liability of the Borrower or any of its
Subsidiaries to the PBGC or such Guaranteed Pension Plan in an aggregate amount
exceeding $5,000,000 and (B) could constitute grounds for the termination of

Court of a trustee to administer such Guaranteed Pension Plan; or (iii) the
institution by the PBGC of proceedings to terminate such Guaranteed Pension
Plan; to the extent that any breach of Section 6.16 or Section 7.20 is a matter
that constitutes a specific breach of a provision of this Section 12.1(l), the
breach of Section 6.16 or Section 7.20 shall not be a Non-Material Breach.

          (m)  Notwithstanding the provisions of Section 8.4(a), any person or
group of persons (within the meaning of Section 13 or 14 of the Securities
Exchange Act of 1934, as amended) shall have acquired beneficial ownership
(within the meaning of Rule 13d-3 promulgated by the Securities and Exchange
Commission under said Act) of 40% or more of the outstanding shares of common
stock of MCRC in a transaction or a series of related transactions and, if at
any time within one (1) year following such acquisition (i) fewer than three (3)
of the five (5) Key Management Individuals (as defined in Section 7.23) remain
active in the executive and/or operational management in their current (or
comparable) positions with MCRC or (ii) individuals who were directors of MCRC
on the date of such acquisition shall cease to constitute a majority of the
voting members of the board of directors of MCRC.

then, and in any such event, so long as the same may be continuing, the
Administrative Agent may, and upon the request of the Required Lenders shall, by
notice in writing to the Borrower, declare all amounts owing with respect to
this Agreement, the Notes and the other Loan Documents and all Reimbursement
Obligations to be, and they shall thereupon forthwith become, immediately due
and payable without presentment, demand, protest or other notice of any kind,
all of which are hereby expressly waived by the Borrower and each Guarantor;
PROVIDED that in the event of any Event of Default specified in Section 12.1(g)
or Section 12.1(h), all such amounts shall become immediately due and payable
automatically and without any requirement of notice from any of the Lenders or
the any of Administrative Agent or action by the Lenders or the Administrative
Agent.

     A Non-Material Breach shall require that the Borrower commence and continue
to exercise reasonable diligent efforts to cure such breach (which shall occur
within any specific time period for curing a Non-Material Breach elsewhere set
forth in this Agreement if any). Such efforts may include (and for a Permitted
Event shall include) the release of the affected Person(s) (other than MCRC) as
the Guarantor pursuant to Section 5 so long as such release (i) cures such
Non-Material Breach (ii) does not otherwise cause a Default or Event of Default,
and (iii) does not have a Material Adverse Effect on the Borrower, the remaining
Guarantors, and their respective Subsidiaries, taken as a whole. Continuing
failure of the Borrower to comply with the requirements to commence and continue
to exercise reasonable diligent efforts to cure such Non-Material

<Page>

                                      -107-

Breach shall constitute a material breach after notice from the Administrative
Agent.

     Section 12.2.  TERMINATION OF COMMITMENTS. If any one or more Events of
Default specified in Section 12.1(g) or Section 12.1(h) shall occur, any unused
portion of the Commitments hereunder shall forthwith terminate and the Lenders
shall be relieved of all obligations to make Loans to the Borrower and the
Administrative Agent and any Fronting Bank shall be relieved of all further
obligations to issue, extend or renew Letters of Credit. If any other Event of
Default shall have occurred and be continuing, whether or not the Lenders shall
have accelerated the maturity of the Loans pursuant to Section 12.1, the
Administrative Agent may, and upon the request of the Required Lenders shall, by
notice to the Borrower, terminate the unused portion of the credit hereunder,
and upon such notice being given such unused portion of the credit hereunder
shall terminate immediately and each of the Lenders shall be relieved of all
further obligations to make Loans, the Administrative Agent and any Fronting
Bank shall be relieved of all further obligations to issue, extend or renew
Letters of Credit. No such termination of the credit hereunder shall relieve the
Borrower or any Guarantor of any of the Obligations or any of its existing
obligations to the Lenders arising under other agreements or instruments.

     Section 12.3.  REMEDIES. In the event that one or more Events of Default
shall have occurred and be continuing, whether or not the Lenders shall have
accelerated the maturity of the Loans pursuant to Section 12.1, the Required
Lenders may direct the Administrative Agent to proceed to protect and enforce
the rights and remedies of the Administrative Agent and the Lenders under this
Agreement, the Notes, any or all of the other Loan Documents or under applicable
law by suit in equity, action at law or other appropriate proceeding (including
for the specific performance of any covenant or agreement contained in this
Agreement or the other Loan Documents or any instrument pursuant to which the
Obligations are evidenced and, to the full extent permitted by applicable law,
the obtaining of the EX PARTE appointment of a receiver), and, if any amount
shall have become due, by declaration or otherwise, proceed to enforce the
payment thereof or any other legal or equitable right or remedy of the
Administrative Agent and the Lenders under the Loan Documents or applicable law.
No remedy herein conferred upon the Lenders or the Administrative Agent or the
holder of any Note or purchaser of any Letter of Credit Participation is
intended to be exclusive of any other remedy and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or
under any of the other Loan Documents or now or hereafter existing at law or in
equity or by statute or any other provision of law.

     Section 13.    SETOFF. Without demand or notice, during the continuance of
any Event of Default, any deposits (general or specific, time or demand,
provisional

<Page>

                                      -108-

or final, regardless of currency, maturity, or the branch at which such deposits
are held, but specifically excluding tenant security deposits, other fiduciary
accounts and other segregated escrow accounts required to be maintained by the
Borrower for the benefit of any third party) or other sums credited by or due
from any of the Lenders to the Borrower or its Subsidiaries or any other
property of the Borrower or its Subsidiaries in the possession of the
Administrative Agent or a Lender may be applied to or set off against the
payment of the Obligations. Each of the Lenders agrees with each other Lender
that (a) if pursuant to any agreement between such Lender and the Borrower
(other than this Agreement or any other Loan Document), an amount to be set off
is to be applied to Indebtedness of the Borrower to such Lender, other than with
respect to the Obligations, such amount shall be applied ratably to such other
Indebtedness and to the Obligations, and (b) if such Lender shall receive from
the Borrower or its Subsidiaries, whether by voluntary payment, exercise of the
right of setoff, counterclaim, cross action, enforcement of the Obligations by
proceedings against the Borrower or its Subsidiaries at law or in equity or by
proof thereof in bankruptcy, reorganization, liquidation, receivership or
similar proceedings, or otherwise, and shall retain and apply to the payment of
the Note or Notes held by, or Reimbursement Obligations owed to, such Lender any
amount in excess of its ratable portion of the payments received by all of the
Lenders with respect to the Notes held by, and Reimbursement Obligations owed
to, all of the Lenders, such Lender will make such disposition and arrangements
with the other Lenders with respect to such excess, either by way of
distribution, PRO TANTO assignment of claims, subrogation or otherwise, as shall
result in each Lender receiving in respect of the Notes held by it or
Reimbursement Obligations owed it, its proportionate payment as contemplated by
this Agreement; PROVIDED that if all or any part of such excess payment is
thereafter recovered from such Lender, such disposition and arrangements shall
be rescinded and the amount restored to the extent of such recovery, but without
interest. Notwithstanding the foregoing, no Lender shall exercise a right of
setoff if such exercise would limit or prevent the exercise of any other remedy
or other recourse against the Borrower or its Subsidiaries; and PROVIDED
FURTHER, if a Lender receives any amount in connection with the enforcement by
such Lender against any particular assets held as collateral for Secured
Indebtedness existing on the date hereof and unrelated to the Obligations which
is owing to such Lender by the Borrower, such Lender shall not be required to
ratably apply such amount to the Obligations.

     Section 14.    THE ADMINISTRATIVE AGENT.

     Section 14.1.  AUTHORIZATION. (a) The Administrative Agent is authorized to
take such action on behalf of each of the Lenders and to exercise all such
powers as are hereunder and under any of the other Loan Documents and any
related documents delegated to the Administrative Agent, together with such
powers as

<Page>

                                      -109-

are reasonably incident thereto, PROVIDED that no duties or responsibilities not
expressly assumed herein or therein shall be implied to have been assumed by the
Administrative Agent. The relationship between the Administrative Agent and the
Lenders is and shall be that of agent and principal only, and nothing contained
in this Agreement or any of the other Loan Documents shall be construed to
constitute the Administrative Agent as a trustee or fiduciary for any Lender.
Subject to the terms and conditions hereof, the Administrative Agent shall
discharge its functions as "Administrative Agent" with the same degree of care
as it performs administrative services for loans in which it is the sole lender.

The Administrative Agent and the Fronting Bank shall be fully justified in
failing or refusing to take any action under Section 3 hereof unless it shall
first have received such advice or concurrence of the Majority Lenders as it
reasonably deems appropriate or it shall first be indemnified to its reasonable
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.

          (b)  The Borrower, without further inquiry or investigation, shall,
and is hereby authorized by the Lenders to, assume that all actions taken by the
Administrative Agent hereunder and in connection with or under the Loan
Documents are duly authorized by the Lenders. The Lenders shall notify the
Borrower of any successor to Administrative Agent in accordance with Section
14.11 by a writing signed by Required Lenders.

     Section 14.2.  EMPLOYEES AND AGENTS. The Administrative Agent may exercise
its powers and execute its duties by or through employees or agents and shall be
entitled to take, and to rely on, advice of counsel concerning all matters
pertaining to its rights and duties under this Agreement and the other Loan
Documents. The Administrative Agent may utilize the services of such Persons as
the Administrative Agent in its sole discretion may reasonably determine, and
all reasonable fees and expenses of any such Persons shall be paid by the
Borrower.

     Section 14.3.  NO LIABILITY. Neither the Administrative Agent, nor any of
its shareholders, directors, officers or employees nor any other Person
assisting them in their duties nor any agent or employee thereof, shall be
liable for any waiver, consent or approval given or any action taken, or omitted
to be taken, in good faith by it or them hereunder or under any of the other
Loan Documents, or in connection herewith or therewith, or be responsible for
the consequences of any oversight or error of judgment whatsoever, except that
the Administrative Agent shall be liable for losses due to its willful
misconduct or gross negligence.

<Page>

                                      -110-

     Section 14.4.  NO REPRESENTATIONS. Neither the Administrative Agent nor the
Syndication Agents shall be responsible for the execution or validity or
enforceability of this Agreement, the Notes, the Letters of Credit, or any of
the other Loan Documents or for the validity, enforceability or collectibility
of any such amounts owing with respect to the Notes, or for any recitals or
statements, warranties or representations made herein or in any of the other
Loan Documents or in any certificate or instrument hereafter furnished to it by
or on behalf of any Guarantor or the Borrower or any of their respective
Subsidiaries, or be bound to ascertain or inquire as to the performance or
observance of any of the terms, conditions, covenants or agreements in this
Agreement or the other Loan Documents. Neither the Administrative Agent nor the
Syndication Agents shall be bound to ascertain whether any notice, consent,
waiver or request delivered to it by the Borrower or any Guarantor or any holder
of any of the Notes shall have been duly authorized or is true, accurate and
complete. Neither the Administrative Agent nor the Syndication Agents has made
nor does it now make any representations or warranties, express or implied, nor
does it assume any liability to the Lenders, with respect to the
creditworthiness or financial condition of the Borrower or any of its
Subsidiaries or any Guarantor or any of the Subsidiaries or any tenant under a
Lease or any other entity. Each Lender acknowledges that it has, independently
and without reliance upon the Administrative Agent, the Syndication Agents or
any other Lender, and based upon such information and documents as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.

     Section 14.5.  PAYMENTS.

          (a)  A payment by the Borrower to the Administrative Agent hereunder
or any of the other Loan Documents for the account of any Lender shall
constitute a payment to such Lender. The Administrative Agent agrees to
distribute to each Lender such Lender's pro rata share of payments received by
the Administrative Agent for the account of the Lenders, as provided herein or
in any of the other Loan Documents. All such payments shall be made on the date
received, if before 1:00 p.m., and if after 1:00 p.m., on the next Business Day.
If payment is not made on the day received, interest thereon at the overnight
federal funds effective rate shall be paid pro rata to the Lenders.

          (b)  If in the reasonable opinion of the Administrative Agent the
distribution of any amount received by it in such capacity hereunder, under the
Notes or under any of the other Loan Documents might involve it in material
liability, it may refrain from making distribution until its right to make
distribution shall have been adjudicated by a court of competent jurisdiction,
PROVIDED that interest thereon at the overnight federal funds effective rate
shall be paid pro rata to the Lenders. If a court of competent jurisdiction
shall adjudge that any amount received and distributed by the Administrative
Agent

<Page>

                                      -111-

is to be repaid, each Person to whom any such distribution shall have been made
shall either repay to the Administrative Agent its proportionate share of the
amount so adjudged to be repaid or shall pay over the same in such manner and to
such Persons as shall be determined by such court.

          (c)  Notwithstanding anything to the contrary contained in this
Agreement or any of the other Loan Documents, any Lender that fails (i) to make
available to the Administrative Agent its pro rata share of any Loan or to
purchase any Letter of Credit Participation or (ii) to comply with the
provisions of Section 13 with respect to making dispositions and arrangements
with the other Lenders, where such Lender's share of any payment received,
whether by setoff or otherwise, is in excess of its pro rata share of such
payments due and payable to all of the Lenders, in each case as, when and to the
full extent required by the provisions of this Agreement, or to adjust promptly
such Lender's outstanding principal and its pro rata Commitment Percentage as
provided in Section 2.1, shall be deemed delinquent (a "DELINQUENT LENDER") and
shall be deemed a Delinquent Lender until such time as such delinquency is
satisfied. A Delinquent Lender shall be deemed to have assigned any and all
payments due to it from the Borrower, whether on account of outstanding Loans,
interest, fees or otherwise, to the remaining nondelinquent Lenders for
application to, and reduction of, their respective pro rata shares of all
outstanding Loans. The Delinquent Lender hereby authorizes the Administrative
Agent to distribute such payments to the nondelinquent Lenders in proportion to
their respective pro rata shares of all outstanding Loans. If not previously
satisfied directly by the Delinquent Lender, a Delinquent Lender shall be deemed
to have satisfied in full a delinquency when and if, as a result of application
of the assigned payments to all outstanding Loans of the nondelinquent Lenders,
the Lenders' respective pro rata shares of all outstanding Loans have returned
to those in effect immediately prior to such delinquency and without giving
effect to the nonpayment causing such delinquency.

     Section 14.6.  HOLDERS OF NOTES. The Administrative Agent may deem and
treat the payee of any Notes or the purchaser of any Letter of Credit
Participation as the absolute owner or purchaser thereof for all purposes hereof
until it shall have been furnished in writing with a different name by such
payee or by a subsequent holder, assignee or transferee.

     Section 14.7.  INDEMNITY. The Lenders ratably and severally agree hereby to
indemnify and hold harmless the Administrative Agent (in its capacity as such
and not in its capacity as a Lender) and its Affiliates from and against any and
all claims, actions and suits (whether groundless or otherwise), losses,
damages, costs, expenses (including any expenses for which the Administrative
Agent has not been reimbursed by the Borrower as required by Section 15), and
liabilities of every nature and character arising out of or related to this
Agreement, the Notes, or

<Page>

                                      -112-

any of the other Loan Documents or the transactions contemplated or evidenced
hereby or thereby, or the Administrative Agent's actions taken hereunder or
thereunder, except to the extent that any of the same shall be directly caused
by the Administrative Agent's or such Affiliate's willful misconduct or gross
negligence.

     Section 14.8.  ADMINISTRATIVE AGENT AS LENDER. In its individual capacity
as a Lender, JPMorgan shall have the same obligations and the same rights,
powers and privileges in respect to its Commitment and the Loans made by it, and
as the holder of any of the Notes and as the purchaser of any Letter of Credit
Participations, as it would have were it not also the Administrative Agent.

     Section 14.9.  NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Lender
hereby agrees that, upon learning of the existence of a default, Default or an
Event of Default, it shall (to the extent notice has not previously been
provided) promptly notify the Administrative Agent thereof. The Administrative
Agent hereby agrees that upon receipt of any notice under this Section 14.9 it
shall promptly notify the other Lenders of the existence of such default,
Default or Event of Default.

     Section 14.10. DUTIES IN THE CASE OF ENFORCEMENT. In case one or more
Events of Default have occurred and shall be continuing, and whether or not
acceleration of the Obligations shall have occurred, the Administrative Agent
shall, if (a) so requested by the Required Lenders and (b) the Lenders have
provided to the Administrative Agent such additional indemnities and assurances
against expenses and liabilities as the Administrative Agent may reasonably
request, proceed to enforce the provisions of this Agreement and exercise all or
any such other legal and equitable and other rights or remedies as it may have
in respect of enforcement of the Lenders' rights against the Borrower and the
Guarantors under this Agreement and the other Loan Documents. The Required
Lenders may direct the Administrative Agent in writing as to the method and the
extent (other than when such direction as to extent requires Unanimous Lender
Approval under Section 25) of any such enforcement, the Lenders (including any
Lender which is not one of the Required Lenders) hereby agreeing to ratably and
severally indemnify and hold the Administrative Agent harmless from all
liabilities incurred in respect of all actions taken or omitted in accordance
with such directions other than actions taken in gross negligence or willful
misconduct, PROVIDED that the Administrative Agent need not comply with any such
direction to the extent that the Administrative Agent reasonably believes the
Administrative Agent's compliance with such direction to be unlawful or
commercially unreasonable in any applicable jurisdiction.

     Section 14.11. SUCCESSOR ADMINISTRATIVE AGENT. JPMorgan, or any successor
Administrative Agent, may resign as Administrative Agent at any time by

<Page>

                                      -113-

giving written notice thereof to the Lenders and to the Borrower. In addition,
the Required Lenders may remove the Administrative Agent in the event of the
Administrative Agent's gross negligence or willful misconduct or in the event
that the Administrative Agent ceases to hold a Commitment of at least
$20,000,000 or a Commitment Percentage of at least five percent (5%) under this
Agreement. Any such resignation or removal shall be effective upon appointment
and acceptance of a successor Administrative Agent, as hereinafter provided.
Subject to the next sentence, any such resignation or removal, the Required
Lenders shall have the right to appoint a successor Administrative Agent, which
is a Lender under this Agreement, PROVIDED that so long as no Default or Event
of Default has occurred and is continuing the Borrower shall have the right to
approve any successor Administrative Agent, which approval shall not be
unreasonably withheld. Notwithstanding the preceding sentence, upon the
resignation of JPMorgan as the Administrative Agent, the Borrower may elect a
Syndication Agent to become the successor Administrative Agent for all purposes
under this Agreement and the other Loan Documents. If, in the case of a
resignation by the Administrative Agent, no successor Administrative Agent shall
have been so appointed by the Required Lenders and, if applicable, approved by
the Borrower, and shall have accepted such appointment, within thirty (30) days
after the retiring Administrative Agent's giving of notice of resignation, then
the retiring Administrative Agent may, on behalf of the Lenders, appoint any one
of the other Lenders as a successor Administrative Agent; PROVIDED that the
Administrative Agent shall have first submitted the names of two (2) Lenders to
the Borrower and, within ten (10) Business Days of such submission the Borrower
shall not have selected one of such Lenders as the successor Administrative
Agent. Upon the acceptance of any appointment as Administrative Agent hereunder
by a successor Administrative Agent, 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 all further duties and
obligations as Administrative Agent under this Agreement. After any
Administrative Agent's resignation or removal hereunder as Administrative Agent,
the provisions of this Section 14 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement.

     Section 14.12. NOTICES. Any notices or other information required hereunder
to be provided to the Administrative Agent and any formal statement or notice
given by the Administrative Agent to the Borrower or any Lender shall be
promptly forwarded by the Administrative Agent to each of the other Lenders.

     Section 15.    EXPENSES. The Borrower agrees to pay (a) the reasonable
costs of incurred by JPMorgan and Fleet and the Arrangers in producing this

harmless the Administrative Agent, the Syndication Agents, the Arrangers and
each of the Lenders and the shareholders, directors, agents, officers,
subsidiaries and affiliates of the Administrative Agent, the Syndication Agents,
the Arrangers and each of the Lenders from and against any and all claims,
actions and suits sought or brought by a third party, whether groundless or
otherwise, and from and against any and all liabilities, losses, settlement
payments, obligations, damages and expenses of every nature and character,
including reasonable legal fees and expenses, arising out of or resulting in any
way from this Agreement or any of the other Loan Documents or the transactions

choice could reasonably be expected to give rise to a conflict of interest, (ii)
the Borrower shall not have employed counsel reasonably satisfactory to the
Administrative Agent, the Syndication Agents, the Arrangers or the Lenders, as
the case may be, within a reasonable time after notice of the institution of any

the case may be, to employ separate counsel at the Borrower's expense. If and to
the extent that the obligations of the Borrower under this Section 16 are
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment in satisfaction of such obligations which is
permissible under applicable law. The provisions of this Section 16 shall
survive the repayment of the Loans and the termination of the obligations of the
Lenders hereunder and shall continue in full force and effect as long as the
possibility of any such claim, action, cause of action or suit exists.

representations and warranties made herein, in the Notes, in any of the other

investigation heretofore or hereafter made by any of them, and shall survive the
making by the Lenders of any of the Loans and the issuance, extension or renewal
of any Letters of Credit, as herein contemplated, and shall continue in full
force and effect so long as any Letter of Credit or any amount due under this
Agreement or the Notes or any of the other Loan Documents remains outstanding or
any Lender has any obligation to make any Loans or the Administrative Agent or

as agent on its behalf and to exercise such powers under this Agreement and the
other Loan Documents as are delegated to the Administrative Agent by the terms

each Assignment and Assumption delivered to it and a register or similar list

and the Commitment Percentages of, and principal amount of the Loans owing to,
the Lenders from time to time. The entries in the Register shall be conclusive,
in the absence of manifest error, and the Borrower, the Administrative Agent and

or more banks or other entities in all or a portion of such Lender's rights and
obligations under this Agreement and the other Loan Documents without notice or
consent of the Borrower, Administrative Agent or any other party hereto;
PROVIDED that (a) any such sale or participation shall not affect the rights and
duties of the selling Lender hereunder to the Borrower and the Administrative
Agent and the Lender shall continue to exercise all approvals, disapprovals and
other functions of a Lender, (b) the only rights granted to the participant
pursuant to such participation arrangements with respect to waivers, amendments
or modifications of, or approvals under, the Loan Documents shall be the rights

behalf of such Designating Lender subject to the terms of this Section 18.10 and
the provisions in Sections 18.1 and 18.5 shall not apply to such designation. No
Lender may designate more than one (1) Designated Bank. The parties to each such
designation shall execute and deliver to the Administrative Agent for its
acceptance a Designation Agreement. Upon such receipt of an appropriately
completed Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Bank, the Administrative Agent will accept
such Designation Agreement and will give prompt notice thereof to the Borrower,
whereupon, (i) the Borrower shall execute and deliver to the Designating Lender
a Designated Bank Note payable to the order of the Designated Bank, (ii) from
and after the effective date specified in the Designation Agreement, the
Designated Bank shall become a party to this Agreement with a right to make
Competitive Bid Loans on behalf of its Designating Lender pursuant to Section 2A
after the Borrower has accepted a Competitive Bid Loan (or portion thereof) of
such Designating Lender, and (iii) the Designated Bank shall not be required to
make payments with respect to any obligations in this Agreement except to the
extent of excess cash flow of such Designated Bank which is not otherwise
required to repay obligations of such Designated Bank which are then due and
payable; PROVIDED, HOWEVER, that regardless of such designation and assumption
by the Designated Bank, the Designating Lender shall be and remain obligated to
the Borrower, the Administrative Agent and the other Lenders for each and every
of the obligations of the Designating Lender and its related Designated Bank
with respect to this Agreement, including, without limitation, any
indemnification obligations hereunder and any sums otherwise payable to the
Borrower by the Designated Bank. Each Designating Lender shall serve as the
administrative agent of the Designated Bank and shall on behalf of, and to the
exclusion of, the Designated Bank: (i) receive any and all payments made for the
benefit of the Designated Bank and (ii) give and receive all communications and
notices and take all actions hereunder, including, without limitation, votes,
approvals, waivers, consents and amendments under or relating to this Agreement
and the other Loan Documents. Any such notice, communication, vote, approval,

administrative agent for the Designated Bank and shall not be signed by the
Designated Bank on its own behalf but shall be binding on the Designated Bank to
the same extent as if actually signed by the Designated Bank. The Borrower, the
Administrative Agent and Lenders may rely thereon without any requirement that
the Designated Bank sign or acknowledge the same. No

<Page>

                                      -121-

     ($4,720,000),  as amended and  restated by Amended and  Restated  Term Note
     between Kings  Brothers and Bank dated as of June 24, 1999, in the original
     principal amount of Three Million Seven Hundred  Forty-Five  Thousand Eight

          e. Patent Security  Agreement dated as of August 30, 2000, among Bank,
     Delaware Color, Logical, Georgia Color and Alorex Corp..

     2.  Guarantors.  Kings Brothers and Dr. Wang  (collectively,  "Guarantors")
have  guaranteed  to Bank full  payment and  performance  by Borrower of all the
Obligations, and those guaranty obligations remain in full force and effect.

     3.  Transaction.  Borrower and  Guarantors  have requested Bank to agree as
follows:

          a.  To  consent  to  the  exchange  by  Delaware  Color  of all of the
     outstanding stock of its wholly-owned  subsidiary,  Logical,  for 1,700,000
     shares of common stock of Delaware Color held by Digital Color Print,  Inc.
     ("DCP"),  a Nevada  corporation,  and a warrant to  purchase  shares of the
     common  stock  of  Logical  or DCP,  as set  forth  in the  Share  Exchange
     Agreement (the "Share Exchange  Agreement") among Delaware Color,  Logical,
     DCP and the shareholders of DCP;

          b. To release Logical from its obligations under the Obligations; and

          c. To release Bank's liens on the assets of Logical.

Bank has agreed to such requests,  subject to the execution and delivery of this
Agreement.

     NOW THEREFORE,  for and in  consideration of ONE HUNDRED DOLLARS ($100) and
other good and valuable consideration,  the receipt and sufficiency of which are
hereby acknowledged, the parties hereto, intending to be legally bound, covenant
and agree as follows:

     1. Recitals;  Definitions.  The foregoing recitals are true and correct and
are hereby incorporated herein by this reference. All capitalized terms utilized
herein,  not  defined  herein but defined in the Loan  Agreement  shall have the
definitions ascribed thereto in the Loan Agreement.

     2. Release of Liability. Effective upon consummation (the "Closing") of the
transactions  set  forth in the  Share  Exchange  Agreement  but not  before  or
otherwise,  Bank releases  Logical from all liabilities and obligations  arising
under the Obligations after the Closing, expressly reserving, however, liability
under the express provisions of this Amendment.  Notwithstanding the immediately
preceding  sentence,  (a) Logical  shall remain liable for all  liabilities  and
obligations  due and payable or to be performed  prior to the Closing and (b) if
at any  time  all or any  part  of any  payment  applied  by  Bank to any of the
Obligations  prior to Closing  must be returned by Bank for any reason,  whether
upon the claim of a preference,  fraudulent transfer,  prior lien or other claim
of  a  creditor,   debtor  in   possession,   trustee  in  bankruptcy  or  other
representative  of  creditors of Borrower,  or  otherwise,  and whether by court

                                       2
<PAGE>

order,  administrative  order or  non-judicial  settlement,  the  obligations of
Logical  shall be  reinstated  and  Logical  shall be liable for the full amount
returned as if such  amount had never been  received  by Bank.  Further,  if the
transaction  described in the Share Exchange Agreement or any portion thereof is
hereafter  rescinded or reversed under  bankruptcy  law,  creditors' or debtors'
rights law or  otherwise,  whether as a preference,  a fraudulent  conveyance or
otherwise,  Logical shall be deemed,  for all purposes and without the execution
and  delivery  of any  further  documentation,  to  have  re-assumed  all of the
Obligations retroactive to the date of Closing.

     3. Release of Collateral.  Upon  effectiveness  of the release of liability
pursuant to the  foregoing  Section 2, Bank shall  release  all liens,  security
interests and  encumbrances  owned by Bank on any personal  property of Logical.
Bank shall execute and deliver such  instruments  as are required to release all
such  liens,   security  interests  and  encumbrances  promptly  upon  Logical's
delivering  to  Bank  the  instruments   required  to  evidence  such  releases.
Notwithstanding the immediately preceding sentence, if the transaction described
in the Share Exchange Agreement or any portion thereof is hereafter rescinded or
reversed under  bankruptcy law,  creditors' or debtors' rights law or otherwise,
whether as a  preference,  a  fraudulent  conveyance  or  otherwise,  the liens,
security  interest of encumbrances  of Bank in the personal  property of Logical
shall be deemed,  for all purposes and without the execution and delivery of any
further documentation, to be reimposed on the assets of Logical. The immediately
preceding  sentence  shall be included in the  release  instruments  executed by
Bank.

     4. Delaware Color and Guarantors. Delaware Color and each of the Guarantors
consents  to the  execution  of this  Agreement,  the release of Logical and the
release of the  collateral  described  above and confirms  that its  obligations
under and in regard to the Obligations remain in full force and effect.

     5.  Conditions.  Bank's  agreements  set forth  herein  are  subject to and
conditioned   upon   satisfaction   of  the   following   conditions  to  Bank's
satisfaction:

          a.  Costs.  Payment by Borrower  of all Bank's  costs and  expenses in
     regard to the investigation,  review and approval of this transaction,  the
     preparation  of this  Agreement and all documents and  agreements  required
     hereby and the administration thereof,  including,  without limitation, (i)
     all legal fees,  expenses and  disbursements  and other actual  third-party
     expense  reimbursements  incurred or sustained by Bank in  connection  with
     this transaction,  (ii) all recording and filing fees,  intangibles  taxes,
     documentary and revenue  stamps,  other taxes or other expenses and charges
     payable in connection  with this Agreement or any agreements or instruments
     executed in connection  herewith and (iii) all costs,  expenses  (including
     fees and expenses of outside consultants), related to the administration of
     the transactions contemplated hereby.

          b. Other Documents. The execution and delivery of such other documents
     and  agreements  as Bank  shall  require to  evidence  and  consummate  the
     transactions described herein.

     6. General Provisions.

          a. Legal Counsel.  Borrower acknowledges and agrees that legal counsel
     to Bank does not represent Borrower as Borrower's  attorney,  that Borrower
     has  retained  (or has had an  opportunity  to  retain)  counsel of its own
     choice and has not and will not rely upon any advice from  Bank's  counsel.
     In no event shall  Borrower's  reimbursement  of expenses  pursuant to this
     Agreement(even  if  effected  by payment  directly  by  Borrower  to Bank's
     counsel) be deemed to establish any  attorney-client  relationship  between
     Borrower and Bank's counsel.

                                       3

          b. No Waiver.  The execution and delivery of this  Agreement  does not
     constitute,  and shall not be construed as, a waiver by Bank of any default
     or Event of Default under any document,  agreement or instrument.  No delay
     or omission of Bank or any subsequent holder of the obligations of Borrower
     to Bank to  exercise  any  right,  remedy,  power or  privilege  after  the
     occurrence  of such  default or Event of Default  shall be  construed  as a
     waiver of any such default, or acquiescence therein.

          c. Headings.  The headings of the articles,  sections,  paragraphs and
     subdivisions  of this Agreement are for  convenience of reference only, are
     not to be considered a part hereof, and shall not limit or otherwise affect
     any of the terms hereof.

          d. Survival of Covenants. All covenants,  agreements,  representations
     and  warranties  made  herein  and in  certificates  or  reports  delivered
     pursuant  hereto  shall be deemed to have been  material  and  relied on by
     Bank,  notwithstanding  any investigation made by or on behalf of Bank, and
     shall survive the execution and delivery to Bank of this Amendment. All the
     terms and  conditions of the  instruments  and  agreements  amended by this
     Agreement are hereby ratified, affirmed and approved as herein amended.

          e. Continuing Obligation; Benefits. This Amendment, and each and every
     provision hereof, is a continuing  obligation and shall (i) be binding upon
     each of the parties  hereto and their  respective  heirs,  representatives,
     successors and assigns, and (ii) inure to the benefit of and be enforceable
     by  the  parties  hereto  and  their  respective  heirs,   representatives,
     successors and assigns; provided, that none of Delaware Color or Guarantors
     or any  thereof  may assign all or any part of this  Agreement  without the
     prior written consent of Bank,  which consent may be granted or withheld in
     the sole discretion of Bank.

          f.  Controlling Law. This Agreement shall be governed by and construed
     in accordance with the laws of the State of Georgia.

          g. Standard of Review. Any document, writing or instrument required or
     permitted  to be  delivered  to Bank under this  Agreement  shall be deemed
     satisfactory  only  if  approved  by  Bank  in the  exercise  of  its  sole
     discretion, and any act or approval permitted to be done by Bank under this
     Agreement shall be in Bank's sole discretion.

          h.  Miscellaneous.  This  Agreement  may not be  varied,  altered,  or
     amended except by a written instrument executed by an authorized officer of
     the Bank.  This  Agreement  may be executed in any number of  counterparts,
     each of which, when executed and delivered,  shall be an original, but such
     counterparts  shall together  constitute one and the same  instrument.  Any
     provision in this Agreement which may be unenforceable or invalid under any
     law  shall  be  ineffective  to the  extent  of  such  unenforceability  or
     invalidity  without  affecting the  enforceability or validity of any other
     provisions hereof.

          i. General Waivers. To the fullest extent permitted by Applicable Law,
     Delaware Color and Guarantors waive (i) presentment, demand and protest and
     notice of presentment,  protest, default,  nonpayment,  maturity,  release,
     compromise,  settlement,  extension  or  renewal  of any or all  commercial
     paper, accounts, contract rights, documents, instruments, chattel paper and
     guaranties  at any time  held by Bank on which  Obligors  may in any way be
     liable;  (ii) notice prior to Bank's  taking  possession  or control of any

                                       4

     collateral  or any bond or  security  which  might be required by any court
     prior to allowing  Bank to exercise any of Bank's  remedies,  including the
     issuance  of an  immediate  writ of  possession;  (iii) the  benefit of all
     valuation,  appraisement and exemption laws; (iv) any right upon payment in
     full of the Obligations to require Bank to terminate its security  interest
     in any  collateral  until the execution of an agreement  indemnifying  Bank
     from any loss or damage Bank may incur as the result of  dishonored  checks
     or other items of payment  received by Bank from any obligor or any Account
     Debtor  and  applied  to the  obligations  owed to Bank;  and (v) notice of
     Bank's acceptance hereof or of any document required hereby.

          j. Loan Documents.  From and after the date hereof,  all references in
     any of the Loan  Documents  to any  document or  agreement  amended by this
     Agreement  shall mean and refer to such document or agreement as amended by
     this Amendment.

          k.  Representations  and  Warranties.  The  parties  hereto,  and  the
     individuals  executing this  Agreement on behalf of all entity  signatories
     hereto,  represent and warrant to Bank that (a) each entity is in existence
     and in good  standing  under  the laws of the  state of  Georgia  and their
     respective  states of organization,  (b) the Articles of Incorporation  and
     Bylaws of all entities have not been amended  since June 30, 2001,  and (c)
     the execution and delivery of this  Agreement  have been  authorized by all
     requisite corporate action by and on behalf of all entities. Delaware Color
     and  Guarantors  hereby  reaffirm and restate  each and every  warranty and
     representation  set forth in the Loan  Agreement  and the  other  documents
     evidencing, securing or otherwise relating to the Obligations.

          l.  Release.  Delaware  Color,  Logical,  Kings  Brothers and Dr. Wang
     hereby waive, release and discharge Bank from any and all claims,  demands,
     actions or causes of action  arising  out of or in any way  relating to the
     Obligations  and any  documents,  agreements,  dealings,  or other  matters
     connected with the Obligations,  including,  without limitation,  all known
     and unknown matters, claims, transactions, or things occurring prior to the
     date of Closing.

          m. No Novation.  This Agreement shall not constitute a novation of the
     Obligations  or of the terms and  provisions of the  documents  evidencing,
     securing and otherwise  relating to the Obligations  shall remain valid and
     in full force and effect as amended here.

          n. No Waiver or Implication.  Nothing herein shall constitute a waiver
     by Bank of any default, whether known or unknown, which may exist under the
     Loan  Documents.  No action,  inaction  or  agreement  by Bank,  including,
     without limitation, any release, extension,  indulgence, waiver, consent or
     agreement of  modification  which may have occurred or have been granted or
     entered  into (or which may be  occurring  or be granted  or  entered  into
     hereunder  or  otherwise)  with  respect to  nonpayment  of the Loan or any
     portion thereof,  or with respect to matters involving security or obligors
     for the Loan,  or with  respect to any other  matter  relating to the Loan,
     shall require or imply any future extension, indulgence, waiver, consent or
     agreement by Bank.  Delaware Color and Guarantors  hereby  acknowledge  and
     agree that Bank has made no agreement, and is in no way obligated, to grant
     any future release, extension,  indulgence,  waiver or consent with respect
     to the Loan or any matter relating to the Loan.
