§2. THE CREDIT FACILITY.

     §2.1 Revolving Credit Loans. Subject to the terms and conditions set forth in this Agreement and the Post Closing
Letter, each of the Revolving Credit Lenders severally agrees to lend to the Borrowers, and the
Borrowers may borrow (and repay and reborrow) from time to time between the Closing Date and the
Revolving Credit Maturity Date upon notice by the Borrowers to the Agent given in accordance with
§2.7, such sums as are requested by the Borrowers for the purposes set forth in §2.9 up to a
maximum aggregate principal amount outstanding (after giving effect to all amounts requested) at
any one time equal to the lesser of (i) such Revolving Credit Lender’s Revolving Credit Commitment
and (ii) such Revolving Credit Lender’s Revolving Credit Commitment Percentage of the sum of (A)
the Borrowing Base Availability minus (B) the sum of (1) the amount of all outstanding
Revolving Credit Loans and Swing Loans, and (2) the aggregate amount of Letter of Credit
Liabilities; provided, that, in all events no Default or Event of Default shall have
occurred and be continuing; and provided, further, that the outstanding principal
amount of the Revolving Credit Loans (after giving effect to all amounts requested), Swing Loans
and Letter of Credit Liabilities shall not at any time exceed the Total Commitment or cause a
violation of the covenant set forth in §9.1. The Revolving Credit Loans shall be made pro
rata in accordance with each Revolving Credit Lender’s Revolving Credit Commitment
Percentage. Each request for a Revolving Credit Loan hereunder shall constitute a representation
and warranty by the Borrowers that all of the conditions required of Borrowers set forth in §10 and
§11 have been satisfied on the date of such request, and to the extent all of the conditions
required of Borrowers set forth in §10 and §11 are not satisfied or deemed satisfied as of the date
of such request, such shall not result in any Material Adverse Effect. The Agent may assume that
the conditions in §10 and §11 have been satisfied unless it receives prior written notice from a
Revolving Credit Lender that such conditions have not been satisfied. No Revolving Credit Lender
shall have any obligation to make Revolving Credit Loans to Borrowers in the maximum aggregate
principal outstanding balance of more than the principal face amount of its Revolving Credit Note
or its Commitment, as applicable.

     §2.2 Notes. The Revolving Credit Loans shall, if requested by each Lender, be evidenced by separate
promissory notes of the Borrowers in substantially the form of Exhibit A hereto
(collectively, the “Revolving Credit Notes”), dated of even date with this Agreement (except as
otherwise provided in §18.3) and completed with appropriate insertions. One Revolving Credit Note
shall be payable to the order of each Revolving Credit Lender which so requests the issuance of a
Revolving Credit Note in the principal amount equal to such Revolving Credit Lender’s Revolving
Credit Commitment or, if less, the outstanding amount of all Revolving Credit Loans made by such
Revolving Credit Lender, plus interest accrued thereon, as set forth below.

     §2.3 Facility Unused Fee. The Borrowers agree to pay to the Agent for the account of the Revolving Credit Lenders
(other than any Defaulting Lender) in accordance with their respective Revolving Credit Commitment
Percentages a facility unused fee calculated at the rate

27

 

per annum as set forth below on the
average daily amount by which the Total Commitment exceeds the outstanding principal amount of
Revolving Credit Loans, Swing Loans and the face amount of Letters of Credit Outstanding during
each calendar quarter or portion thereof commencing on the date hereof and ending on the Revolving
Credit Maturity Date; provided such fee shall not accrue until one hundred and twenty (120) days
after the Closing Date. The facility unused fee shall be calculated for each day based on the
ratio (expressed as a percentage) of (a) the average daily amount of the outstanding principal
amount of the Revolving Credit Loans and Swing Loans and the face amount of Letters of Credit
Outstanding during such quarter to (b) the Total Commitment, and if such ratio is less than or
equal to fifty percent (50%), the facility unused fee shall be payable at the rate of 0.50%, and if
such ratio is greater than fifty percent (50%), the facility unused fee shall be payable at the
rate of 0.40%. The facility unused fee shall be payable quarterly in arrears on the fifth
(5th) day of each calendar quarter for the immediately preceding calendar quarter or
portion thereof, and on any earlier date on which the Revolving Credit Commitments shall be reduced
or shall terminate as provided in §2.4, with a final payment on the Revolving Credit Maturity Date.

     §2.4 Reduction and Termination of the Revolving Credit Commitments. The Borrowers shall have the right at any time and from time to time upon five (5) Business
Days’ prior written notice to the Agent to reduce by $5,000,000 or an integral multiple of
$1,000,000 in excess thereof (provided that in no event shall the Total Commitment be
reduced in such manner to an amount less than $50,000,000) or to terminate entirely the Revolving
Credit Commitments, whereupon the Revolving Credit Commitments of the Revolving Credit Lenders
shall be reduced pro rata in accordance with their respective Revolving Credit Commitment
Percentages of the amount specified in such notice or, as the case may be, terminated, any such
termination or reduction to be without penalty except as otherwise set forth in §4.8;
provided, however, that no such termination or reduction shall be permitted if,
after giving effect thereto, the sum of Outstanding Revolving Credit Loans, the Outstanding Swing
Loans and the Letter of Credit Liabilities would exceed the Revolving Credit Commitments of the
Revolving Credit Lenders as so terminated or reduced. Promptly after receiving any notice from the
Borrowers delivered pursuant to this §2.4, the Agent will notify the Revolving Credit Lenders of
the substance thereof. Any reduction of the Revolving Credit Commitments shall also result in a
proportionate reduction (rounded to the next lowest integral multiple of $100,000) in the maximum
amount of Swing Loans and Letters of Credit. Upon the effective date of any such reduction or
termination, the Borrowers shall pay to the Agent for the respective accounts of the Revolving
Credit Lenders the full amount of any facility fee under §2.3 then accrued on the amount of the
reduction. No reduction or termination of the Revolving Credit Commitments may be reinstated.

     §2.5 Swing Loan Commitment.

          (a) Subject to the terms and conditions set forth in this Agreement, Swing Loan Lender agrees
to lend to the Borrowers (the “Swing Loans”), and the Borrowers may borrow (and repay and reborrow)
from time to time between the Closing Date and the date which is five (5) Business Days prior to
the Revolving Credit Maturity Date upon notice by the Borrowers to the Swing Loan Lender given in
accordance with this §2.5, such sums as are requested by the Borrowers for the purposes set forth
in §2.9 in an aggregate principal amount at any one time outstanding not exceeding the Swing Loan
Commitment; provided that in all events (i) no Default or Event of Default shall have
occurred and be continuing; (ii) no Revolving

28

 

Credit Lender shall be a Defaulting Lender (provided
Swing Loan Lender may, in its sole discretion, be entitled to waive this condition); (iii) the
outstanding principal amount of the Revolving Credit Loans and Swing Loans (after giving effect to
all amounts requested) plus Letter of Credit Liabilities shall not at any time exceed the
Total Commitment; and (iv) the outstanding principal amount of the Revolving Credit Loans and Swing
Loans (after giving effect to all amounts requested), plus Letter of Credit Liabilities shall not
at any time exceed the lesser of (A) the Total Commitment or (B) the Borrowing Base Availability.
Swing Loans shall constitute “Revolving Credit Loans” for all purposes hereunder. The funding of a
Swing Loan hereunder shall constitute a representation and warranty by the Borrowers that all of
the conditions set forth in §10 and §11 have been satisfied on the date of such funding. The Swing
Loan Lender may assume that the conditions in §10 and §11 have been satisfied unless Swing Loan
Lender has received written notice from a Revolving Credit Lender that such conditions have not
been satisfied. Each Swing Loan shall be due and payable within five (5) Business Days of the date
such Swing Loan was provided and Borrowers hereby agree (to the extent not repaid as contemplated
by §2.5(d) below) to repay each Swing Loan on or before the date that is five (5) Business Days
from the date such Swing Loan was provided.

          (b) The Swing Loans shall be evidenced by a separate promissory note of the Borrowers in
substantially the form of Exhibit B hereto (the “Swing Note”), dated the date of this
Agreement and completed with appropriate insertions. The Swing Loan Note shall be payable to the
order of the Swing Loan Lender in the principal face amount equal to the Swing Loan Commitment and
shall be payable as set forth below.

          (c) Borrowers shall request a Swing Loan by delivering to the Swing Loan Lender a Loan Request
executed by an Authorized Officer no later than 1:00 p.m. (Eastern time) on the requested Drawdown
Date specifying the amount of the requested Swing Loan (which shall be in the minimum amount of
$1,000,000) and providing the wire instructions for the delivery of the Swing Loan proceeds. The
Loan Request shall also contain the statements and certifications required by §2.7(i) and (ii).
Each such Loan Request shall be irrevocable and binding on the Borrowers and shall obligate the
Borrowers to accept such Swing Loan on the Drawdown Date. Notwithstanding anything herein to the
contrary, a Swing Loan shall be a Base Rate Loan and shall bear interest at the Base Rate plus the
Applicable Margin for Revolving Credit Base Rate Loans. The proceeds of the Swing Loan will be
disbursed by wire by the Swing Loan Lender to the Borrowers no later than 3:00 p.m. (Eastern time).

          (d) The Swing Loan Lender shall, within two (2) Business Days after the Drawdown Date with
respect to such Swing Loan, request each Revolving Credit Lender, including the Swing Loan Lender,
to make a Revolving Credit Loan pursuant to §2.1 in an amount equal to such Revolving Credit
Lender’s Revolving Credit Commitment Percentage of
the amount of the Swing Loan outstanding on the date such notice is given. In the event that
the Borrowers do not notify the Agent in writing otherwise on or before noon (Eastern time) of the
second (2nd) Business Day after the Drawdown Date with respect to such Swing Loan, Agent
shall notify the Revolving Credit Lenders that such Revolving Credit Loan shall be a Revolving
Credit LIBOR Rate Loan with an Interest Period of one (1) month, provided that the making of such
Revolving Credit LIBOR Rate Loan will not be in contravention of any other provision of this
Agreement, or if the making of a Revolving Credit LIBOR Rate Loan would be in contravention of this
Agreement, then such notice shall indicate that such loan shall be a

29

 

Revolving Credit Base Rate
Loan. Borrowers hereby irrevocably authorize and direct the Swing Loan Lender to so act on its
behalf, and agrees that any amount advanced to the Agent for the benefit of the Swing Loan Lender
pursuant to this §2.5(d) shall be considered a Revolving Credit Loan pursuant to §2.1. Unless any
of the events described in paragraph (h), (i) or (j) of §12.1 shall have occurred (in which event
the procedures of §2.5(e) shall apply), each Revolving Credit Lender shall make the proceeds of its
Revolving Credit Loan available to the Swing Loan Lender for the account of the Swing Loan Lender
at the Agent’s Head Office prior to 12:00 noon (Eastern time) in funds immediately available no
later than the third (3rd) Business Day after the date such notice is given just as if the
Revolving Credit Lenders were funding directly to the Borrowers, so that thereafter such
Obligations shall be evidenced by the Revolving Credit Notes. The proceeds of such Revolving
Credit Loan shall be immediately applied to repay the Swing Loans.

          (e) If for any reason a Swing Loan cannot be refinanced by a Revolving Credit Loan pursuant to
§2.5(d) (including due to a Defaulting Lender’s failure to fund), each Revolving Credit Lender
will, on the date such Revolving Credit Loan pursuant to §2.5(d) was to have been made, purchase an
undivided participation interest in the Swing Loan in an amount equal to its Revolving Credit
Commitment Percentage of such Swing Loan (or portion thereof). Each Revolving Credit Lender will
immediately transfer to the Swing Loan Lender in immediately available funds the amount of its
participation and upon receipt thereof the Swing Loan Lender will deliver to such Revolving Credit
Lender a Swing Loan participation certificate dated the date of receipt of such funds and in such
amount.

          (f) Whenever at any time after the Swing Loan Lender has received from any Revolving Credit
Lender such Revolving Credit Lender’s participation interest in a Swing Loan, the Swing Loan Lender
receives any payment on account thereof, the Swing Loan Lender will distribute to such Revolving
Credit Lender its participation interest in such amount (appropriately adjusted in the case of
interest payments to reflect the period of time during which such Revolving Credit Lender’s
participating interest was outstanding and funded); provided, however, that in the
event that such payment received by the Swing Loan Lender is required to be returned, such
Revolving Credit Lender will return to the Swing Loan Lender any portion thereof previously
distributed by the Swing Loan Lender to it.

          (g) Each Revolving Credit Lender’s obligation to fund a Revolving Credit Loan as provided in
§2.5(d) or to purchase participation interests pursuant to §2.5(e) shall be absolute and
unconditional and shall not be affected by any circumstance, including, without limitation, (i) any
setoff, counterclaim, recoupment, defense or other right which such Revolving Credit Lender or the
Borrowers may have against the Swing Loan Lender, the Borrowers or anyone else for any reason
whatsoever; (ii) the occurrence or continuance of a Default or an
Event of Default; (iii) any adverse change in the condition (financial or otherwise) of the
Borrowers or any of their respective Subsidiaries; (iv) any breach of this Agreement or any of the
other Loan Documents by the Borrowers or any Lender; or (v) any other circumstance, happening or
event whatsoever, whether or not similar to any of the foregoing. Any portions of a Swing Loan not
so purchased or converted may be treated by the Agent and Swing Loan Lender as against such
Revolving Credit Lender as a Revolving Credit Loan which was not funded by the non-purchasing
Revolving Credit Lender as contemplated by §2.8 and §12.5, and shall have such rights and remedies
against such Revolving Credit Lender as are set forth in

30

 

§§2.8, 12.5 and 14.5. Each Swing Loan,
once so sold or converted, shall cease to be a Swing Loan for the purposes of this Agreement, but
shall be a Revolving Credit Loan made by each Revolving Credit Lender under its Revolving Credit
Commitment.

     §2.6 Interest on Loans.

          (a) Each Revolving Credit Base Rate Loan shall bear interest for the period commencing with
the Drawdown Date thereof and ending on the date on which such Revolving Credit Base Rate Loan is
repaid or converted to a Revolving Credit LIBOR Rate Loan at the rate per annum equal to the sum of
the Base Rate plus the Applicable Margin for Revolving Credit Base Rate Loans.

          (b) Each Revolving Credit LIBOR Rate Loan shall bear interest for the period commencing with
the Drawdown Date thereof and ending on the last day of each Interest Period with respect thereto
at the rate per annum equal to the sum of LIBOR determined for such Interest Period plus the
Applicable Margin for Revolving Credit LIBOR Rate Loans.

          (c) The Borrowers promise to pay interest on each Loan in arrears on each Interest Payment
Date with respect thereto.

          (d) Base Rate Loans and LIBOR Rate Loans may be converted to Loans of the other Type as
provided in §4.1.

     §2.7 Requests for Revolving Credit Loans. Except with respect to the initial Revolving Credit Loan on the Closing Date, the Borrowers
shall give to the Agent written notice executed by an Authorized Officer in the form of Exhibit
D hereto (or telephonic notice confirmed in writing in the form of Exhibit D hereto) of
each Revolving Credit Loan requested hereunder (a “Loan Request”) by 1:00 p.m. (Eastern time) one
(1) Business Day prior to the proposed Drawdown Date with respect to Revolving Credit Base Rate
Loans and two (2) Business Days prior to the proposed Drawdown Date with respect to Revolving
Credit LIBOR Rate Loans. Each such notice shall specify with respect to the requested Revolving
Credit Loan the proposed principal amount of such Revolving Credit Loan, the Type of Revolving
Credit Loan, the initial Interest Period (if applicable) for such Revolving Credit Loan and the
Drawdown Date. Promptly upon receipt of any such notice, the Agent shall notify each of the
Revolving Credit Lenders thereof. Each such Loan Request shall be irrevocable and binding on the
Borrowers and shall obligate the Borrowers to accept the Revolving Credit Loan requested from the
Revolving Credit Lenders on the proposed Drawdown Date. Nothing herein shall prevent the Borrowers
from seeking recourse against any Revolving
Credit Lender that fails to advance its proportionate share of a requested Revolving Credit
Loan as required by this Agreement. Each Loan Request shall be (a) for a Revolving Credit Base
Rate Loan in a minimum aggregate amount of $1,000,000 or an integral multiple of $100,000 in excess
thereof; or (b) for a Revolving Credit LIBOR Rate Loan in a minimum aggregate amount of $1,000,000
or an integral multiple of $250,000 in excess thereof; provided, however, that
there shall be no more than ten (10) Revolving Credit LIBOR Rate Loans outstanding at any one time.

31

 

     §2.8 Funds for Loans.

          (a) Not later than 3:00 p.m. (Eastern time) on the proposed Drawdown Date of any Revolving
Credit Loans, each of the Revolving Credit Lenders will make available to the Agent, at the Agent’s
Head Office, in immediately available funds, the amount of such Lender’s Commitment Percentage of
the amount of the requested Loans which may be disbursed pursuant to §2.1 or §2.2. Upon receipt
from each such Revolving Credit Lender of such amount, and upon receipt of the documents required
by §10 and §11 and the satisfaction of the other conditions set forth therein, to the extent
applicable, the Agent will make available to the Borrowers the aggregate amount of such Revolving
Credit Loans made available to the Agent by the Revolving Credit Lenders by crediting such amount
to the account of the Borrowers maintained at the Agent’s Head Office. The failure or refusal of
any Revolving Credit Lender to make available to the Agent at the aforesaid time and place on any
Drawdown Date the amount of its Commitment Percentage of the requested Loans shall not relieve any
other Revolving Credit Lender from its several obligation hereunder to make available to the Agent
the amount of such other Lender’s Commitment Percentage of any requested Loans, including any
additional Revolving Credit Loans that may be requested subject to the terms and conditions hereof
to provide funds to replace those not advanced by the Lender so failing or refusing. In the event
of any such failure or refusal, the Lenders not so failing or refusing shall be entitled to a
priority secured position as against the Lender or Lenders so failing or refusing to make available
to the Borrowers the amount of its or their Commitment Percentage for such Loans as provided in
§12.5.

          (b) Unless the Agent shall have been notified by any Lender prior to the applicable Drawdown
Date that such Lender will not make available to Agent such Lender’s Commitment Percentage of a
proposed Loan, Agent may in its discretion assume that such Lender has made such Loan available to
Agent in accordance with the provisions of this Agreement and the Agent may, if it chooses, in
reliance upon such assumption make such Loan available to the Borrowers, and such Lender shall be
liable to the Agent for the amount of such advance. If such Lender does not pay such corresponding
amount upon the Agent’s demand therefor, the Agent will promptly notify the Borrowers, and the
Borrowers shall promptly pay such corresponding amount to the Agent. The Agent shall also be
entitled to recover from the Lender or the Borrowers, as the case may be, interest on such
corresponding amount in respect of each day from the date such corresponding amount was made
available by the Agent to the Borrowers to the date such corresponding amount is recovered by the
Agent at a per annum rate equal to (i) from the Borrowers at the applicable rate for such Loan or
(ii) from a Lender at the Federal Funds Effective Rate.

     §2.9 Use of Proceeds. The Borrowers will use the proceeds of the Loans and the Letters of Credit solely to (a)
pay closing costs in connection with this Agreement; (b) repay existing construction loans, fund
future redevelopment and/or development projects, tenant improvements within Net Rentable Area and
property and equipment acquisitions; (c) to make Distributions permitted by this Agreement; and (d)
for general working capital purposes (including to finance direct and indirect investments in real
estate used or intended to be used as a data center).

32

 

     §2.10 Letters of Credit.

          (a) Subject to the terms and conditions set forth in this Agreement, at any time and from time
to time from the Closing Date through the day that is thirty (30) Business Days prior to the
Revolving Credit Maturity Date, the Issuing Lender shall issue such Letters of Credit as the
Borrowers may request upon the delivery of a written request in the form of Exhibit E
hereto (a “Letter of Credit Request”) to the Issuing Lender, provided that (i) no Default
or Event of Default shall have occurred and be continuing, (ii) upon issuance of such Letter of
Credit, the Letter of Credit Liabilities shall not exceed Thirty-Five Million Dollars ($35,000,000)
but shall be automatically increased on a pro rata basis with increases in the Total Commitment,
(iii) in no event shall the sum of (A) the Revolving Credit Loans Outstanding, (B) the Swing Loans
Outstanding and (C) the amount of Letter of Credit Liabilities (after giving effect to all Letters
of Credit requested) exceed the Total Commitment, (iv) in no event shall the outstanding principal
amount of the Revolving Credit Loans, Swing Loans and Letters of Credit Liabilities (after giving
effect to any requested Letters of Credit) exceed the Total Commitment or the Borrowing Base
Availability or cause a violation of the covenant set forth in §9.1, (v) the conditions set forth
in §§10 and 11 shall have been satisfied, (vi) no Revolving Credit Lender is a Defaulting Lender
(provided Issuing Lender may, in its sole discretion, be entitled to waive this condition), unless
the Issuing Lender has entered into arrangements, including the delivery of cash collateral,
satisfactory to the Issuing Lender (in its sole discretion) with the Borrower or such Defaulting
Lender to eliminate the Issuing Lender’s actual or potential Fronting Exposure with respect to the
Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that
Letter of Credit and all other Letter of Credit Liabilities as to which the Issuing Lender has
actual or potential Fronting Exposure, as it may elect in its sole discretion, and (vii) in no
event shall any amount drawn under a Letter of Credit be available for reinstatement or a
subsequent drawing under such Letter of Credit. The Issuing Lender may assume that the conditions
in §10 and §11 have been satisfied unless it receives written notice from a Revolving Credit Lender
that such conditions have not been satisfied. Each Letter of Credit Request shall be executed by
an Authorized Officer of Borrowers. The Issuing Lender shall be entitled to conclusively rely on
such Person’s authority to request a Letter of Credit on behalf of Borrowers. The Issuing Lender
shall have no duty to verify the authenticity of any signature appearing on a Letter of Credit
Request. The Borrowers assume all risks with respect to the use of the Letters of Credit. Unless
the Issuing Lender and the Majority Lenders otherwise consent, the term of any Letter of Credit
shall not exceed a period of time commencing on the issuance of the Letter of Credit and ending one
year after the date of issuance thereof, subject to extension pursuant to an “evergreen” clause
reasonably acceptable to Agent and Issuing Lender (but in any event the term shall not extend
beyond the Revolving Credit Maturity Date). The amount available to be drawn under any Letter of
Credit shall reduce on a dollar-for-dollar basis the amount available to be drawn under the Total
Commitment as a Revolving Credit Loan.

          (b) Each Letter of Credit Request shall be submitted to the Issuing Lender at least three (3)
Business Days (or such shorter period as the Issuing Lender may approve) prior to the date upon
which the requested Letter of Credit is to be issued. Each such Letter of Credit Request shall
contain (i) a statement as to the purpose for which such Letter of Credit shall be used (which
purpose shall be in accordance with the terms of this Agreement), and (ii) a certification by an
Authorized Officer or the chief financial or chief accounting officer of Parent Borrower that the
Borrowers are and will be in compliance with all covenants under the Loan Documents after giving
effect to the issuance of such Letter of Credit. The Borrowers shall further deliver to the
Issuing Lender such additional applications (which application as of the

33

 

date hereof is in the form
of Exhibit I attached hereto) and documents as the Issuing Lender may require, in
conformity with the then standard practices of its letter of credit department applicable to all or
substantially all similarly situated borrowers, in connection with the issuance of such Letter of
Credit; provided that in the event of any conflict, the terms of this Agreement shall
control.

          (c) The Issuing Lender shall, subject to the conditions set forth in this Agreement, issue the
Letter of Credit on or before three (3) Business Days following receipt of the documents last due
pursuant to §2.10(b). Each Letter of Credit shall be in form and substance reasonably satisfactory
to the Issuing Lender in its reasonable discretion.

          (d) Upon the issuance of a Letter of Credit, each Revolving Credit Lender shall be deemed to
have purchased a participation therein from Issuing Lender in an amount equal to its respective
Commitment Percentage of the amount of such Letter of Credit. No Revolving Credit Lender’s
obligation to participate in a Letter of Credit shall be affected by any other Revolving Credit
Lender’s failure to perform as required herein with respect to such Letter of Credit or any other
Letter of Credit.

          (e) Upon the issuance of each Letter of Credit, the Borrowers shall pay to the Issuing Lender
(i) for its own account, a Letter of Credit fronting fee calculated at the rate set forth in the
Agreement Regarding Fees, and (ii) for the accounts of the Revolving Credit Lenders (including the
Issuing Lender) in accordance with their respective percentage shares of participation in such
Letter of Credit, a Letter of Credit fee calculated at the rate per annum equal to the Applicable
Margin then applicable to Revolving Credit LIBOR Rate Loans on the amount available to be drawn
under such Letter of Credit. Such fees shall be payable in quarterly installments in arrears with
respect to each Letter of Credit on the fifth day of each calendar quarter following the date of
issuance and continuing on each quarter or portion thereof thereafter, as applicable, or on any
earlier date on which the Commitments shall terminate and on the expiration or return of any Letter
of Credit. In addition, the Borrowers shall pay to Issuing Lender for its own account within ten
(10) Business Days of demand of Issuing Lender the standard issuance, documentation and service
charges applicable to all or substantially all similarly situated borrowers for Letters of Credit
issued from time to time by Issuing Lender.

          (f) In the event that any amount is drawn under a Letter of Credit by the beneficiary thereof,
the Borrowers shall reimburse the Issuing Lender by having such amount drawn treated as an
outstanding Revolving Credit Base Rate Loan under this Agreement (Borrowers being deemed to have
requested a Revolving Credit Base Rate Loan on such date in an amount equal to the amount of such
drawing and such amount drawn shall be treated as an
outstanding Revolving Credit Base Rate Loan under this Agreement) and the Agent shall promptly
notify each Revolving Credit Lender by telex, telecopy, telegram, telephone (confirmed in writing)
or other similar means of transmission, and each Revolving Credit Lender shall promptly and
unconditionally pay to the Agent, for the Issuing Lender’s own account, an amount equal to such
Revolving Credit Lender’s Revolving Credit Commitment Percentage of such Letter of Credit (to the
extent of the amount drawn). Borrowers further hereby irrevocably authorize and direct Agent to
notify the Revolving Credit Lenders of Borrowers’ intent to convert such Revolving Credit Base Rate
Loan to a Revolving Credit LIBOR Rate Loan with an Interest Period of one (1) month on the third
(3rd) Business Day following the funding by the

34

 

Revolving Credit Lenders of their
advance under this §2.10(f), provided that the making of such Revolving Credit LIBOR Rate Loan
shall not be a contravention of any provision of this Agreement. If and to the extent any
Revolving Credit Lender shall not make such amount available on the Business Day on which such draw
is funded, such Revolving Credit Lender agrees to pay such amount to the Agent forthwith on demand,
together with interest thereon, for each day from the date on which such draw was funded until the
date on which such amount is paid to the Agent, at the Federal Funds Effective Rate until three (3)
days after the date on which the Agent gives notice of such draw and at the Federal Funds Effective
Rate plus one percent (1.0%) for each day thereafter. Further, such Revolving Credit Lender shall
be deemed to have assigned any and all payments made of principal and interest on its Revolving
Credit Loans, amounts due with respect to its participations in Letters of Credit and any other
amounts due to it hereunder to the Agent to fund the amount of any drawn Letter of Credit which
such Revolving Credit Lender was required to fund pursuant to this §2.10(f) until such amount has
been funded (as a result of such assignment or otherwise). In the event of any such failure or
refusal, the Revolving Credit Lenders not so failing or refusing shall be entitled to a priority
secured position for such amounts as provided in §12.5. The failure of any Revolving Credit Lender
to make funds available to the Agent in such amount shall not relieve any other Revolving Credit
Lender of its obligation hereunder to make funds available to the Agent pursuant to this §2.10(f).

          (g) If after the issuance of a Letter of Credit pursuant to §2.10(c) by the Issuing Lender,
but prior to the funding of any portion thereof by a Revolving Credit Lender, for any reason a
drawing under a Letter of Credit cannot be refinanced as a Revolving Credit Loan, each Revolving
Credit Lender will, on the date such Revolving Credit Loan pursuant to §2.10(f) was to have been
made, purchase an undivided participation interest in the Letter of Credit in an amount equal to
its Revolving Credit Commitment Percentage of the amount of such Letter of Credit. Each Revolving
Credit Lender will immediately transfer to the Issuing Lender in immediately available funds the
amount of its participation and upon receipt thereof the Issuing Lender will deliver to such
Revolving Credit Lender a Letter of Credit participation certificate dated the date of receipt of
such funds and in such amount.

          (h) Whenever at any time after the Issuing Lender has received from any Revolving Credit
Lender any such Revolving Credit Lender’s payment of funds under a Letter of Credit and thereafter
the Issuing Lender receives any payment on account thereof, then the Issuing Lender will distribute
to such Revolving Credit Lender its participation interest in such amount (appropriately adjusted
in the case of interest payments to reflect the period of time during which such Revolving Credit
Lender’s participation interest was outstanding and funded); provided, however,
that in the event that such payment received by the Issuing Lender is
required to be returned, such Revolving Credit Lender will return to the Issuing Lender any
portion thereof previously distributed by the Issuing Lender to it.

          (i) The issuance of any supplement, modification, amendment, renewal or extension to or of any
Letter of Credit shall be treated in all respects the same as the issuance of a new Letter of
Credit.

          (j) Borrowers assume all risks of the acts, omissions, or misuse of any Letter of Credit by
the beneficiary thereof. Neither Agent, Issuing Lender nor any Lender will be responsible for (i)
the form, validity, sufficiency, accuracy, genuineness or legal effect of any

35

 

Letter of Credit or
any document submitted by any party in connection with the issuance of any Letter of Credit, even
if such document should in fact prove to be in any or all respects invalid, insufficient,
inaccurate, fraudulent or forged; (ii) the form, validity, sufficiency, accuracy, genuineness or
legal effect of any instrument transferring or assigning or purporting to transfer or assign any
Letter of Credit or the rights or benefits thereunder or proceeds thereof in whole or in part,
which may prove to be invalid or ineffective for any reason; (iii) failure of any beneficiary of
any Letter of Credit to comply fully with the conditions required in order to demand payment under
a Letter of Credit; (iv) errors, omissions, interruptions or delays in transmission or delivery of
any messages, by mail, cable, telegraph, telex or otherwise; (v) errors in interpretation of
technical terms; (vi) any loss or delay in the transmission or otherwise of any document or draft
required by or from a beneficiary in order to make a disbursement under a Letter of Credit or the
proceeds thereof; (vii) for the misapplication by the beneficiary of any Letter of Credit of the
proceeds of any drawing under such Letter of Credit; and (viii) for any consequences arising from
causes beyond the control of Agent or any Lender. None of the foregoing will affect, impair or
prevent the vesting of any of the rights or powers granted to Agent, Issuing Lender or the Lenders
hereunder. In furtherance and extension and not in limitation or derogation of any of the
foregoing, any act taken or omitted to be taken by Agent, Issuing Lender or the other Lenders in
good faith will be binding on Borrowers and will not put Agent, Issuing Lender or the other Lenders
under any resulting liability to Borrowers; provided nothing contained herein shall relieve
Issuing Lender for liability to Borrowers arising as a result of the gross negligence or willful
misconduct of Issuing Lender as determined by a court of competent jurisdiction after the
exhaustion of all applicable appeal periods.

     §2.11 Increase in Total Commitment.

          (a) Provided that no Default or Event of Default has occurred and is continuing, subject to
the terms and conditions set forth in this §2.11, the Borrowers shall have the option at any time
and from time to time before the date that is thirty (30) days prior to the Revolving Credit
Maturity Date (or the extended maturity date if Borrowers exercise their extension option pursuant
to §2.12) to request an increase in the Total Commitment to not more than $200,000,000 by giving
written notice to the Agent (an “Increase Notice”; and the amount of such requested increase is the
“Commitment Increase”), provided that any such individual increase must be in a minimum
amount of $25,000,000. Upon receipt of any Increase Notice, the Agent shall consult with Arrangers
and shall notify the Borrowers of the amount of facility fees to be paid to any Revolving Credit
Lenders who provide an additional Revolving Credit Commitment in connection with such increase in
the Total Commitment (which shall be in addition to the fees to be paid to Agent or Arrangers
pursuant to the Agreement Regarding Fees).
If the Borrowers agree to pay the facility fees so determined, then the Agent shall send a
notice to all Revolving Credit Lenders (the “Additional Commitment Request Notice”) informing them
of the Borrowers’ request to increase the Total Commitment and of the facility fees to be paid with
respect thereto. Each Revolving Credit Lender who desires to provide an additional Revolving
Credit Commitment upon such terms shall provide Agent with a written commitment letter specifying
the amount of the additional Revolving Credit Commitment by which it is willing to provide prior to
such deadline as may be specified in the Additional Commitment Request Notice. If the requested
increase is oversubscribed then the Agent and the Arrangers shall allocate the Commitment Increase
among the Revolving Credit Lenders who provide such commitment letters on such basis mutually
acceptable to each of the Borrowers, Agent and

36

 

Arrangers. If the additional Revolving Credit
Commitments so provided are not sufficient to provide the full amount of the Commitment Increase
requested by the Borrowers, then the Agent, Arrangers or Borrowers may, but shall not be obligated
to, invite one or more banks or lending institutions (which banks or lending institutions shall be
reasonably acceptable to Agent, Arrangers and Parent Borrower) to become a Revolving Credit Lender
and provide an additional Revolving Credit Commitment. The Agent shall provide all Revolving
Credit Lenders with a notice setting forth the amount, if any, of the additional Revolving Credit
Commitment to be provided by each Revolving Credit Lender and the revised Revolving Credit
Commitment Percentages which shall be applicable after the effective date of the Commitment
Increase specified therein (the “Commitment Increase Date”). In no event shall any Revolving
Credit Lender be obligated to provide an additional Revolving Credit Commitment.

          (b) On any Commitment Increase Date the outstanding principal balance of the Revolving Credit
Loans shall be reallocated among the Revolving Credit Lenders such that after the applicable
Commitment Increase Date the outstanding principal amount of Revolving Credit Loans owed to each
Revolving Credit Lender shall be equal to such Revolving Credit Lender’s Revolving Credit
Commitment Percentage (as in effect after the applicable Commitment Increase Date) of the
outstanding principal amount of all Revolving Credit Loans. The participation interests of the
Revolving Credit Lenders in Swing Loans and Letters of Credit shall be similarly adjusted. On any
Commitment Increase Date those Revolving Credit Lenders whose Revolving Credit Commitment
Percentage is increasing shall advance the funds to the Agent and the funds so advanced shall be
distributed among the Revolving Credit Lenders whose Revolving Credit Commitment Percentage is
decreasing as necessary to accomplish the required reallocation of the outstanding Revolving Credit
Loans. The funds so advanced shall be Revolving Credit Base Rate Loans until converted to
Revolving Credit LIBOR Rate Loans which are allocated among all Revolving Credit Lenders based on
their Revolving Credit Commitment Percentages.

          (c) Upon the effective date of each increase in the Total Commitment pursuant to this §2.11
the Agent may unilaterally revise Schedule 1.1 and the Borrowers shall, if requested by
such Lender, execute and deliver to the Agent new Revolving Credit Notes for each Revolving Credit
Lender whose Revolving Credit Commitment has changed so that the principal amount of such Revolving
Credit Lender’s Revolving Credit Note shall equal its Revolving Credit Commitment. The Agent shall
deliver such replacement Revolving Credit Notes to the respective Revolving Credit Lenders in
exchange for the Revolving Credit Notes replaced thereby which shall be surrendered by such
Revolving Credit Lenders. Such new Revolving Credit Notes shall provide that they are replacements
for the surrendered Revolving Credit Notes
and that they do not constitute a novation, shall be dated as of the Commitment Increase Date
and shall otherwise be in substantially the form of the replaced Revolving Credit Notes.

          (d) Notwithstanding anything to the contrary contained herein, the obligation of the Agent and
the Revolving Credit Lenders to increase the Total Commitment pursuant to this §2.11 shall be
conditioned upon satisfaction or waiver of the following conditions precedent which must be
satisfied or waived prior to the effectiveness of any increase of the Total Commitment:

37

 

               (i) Payment of Activation Fee. The Borrowers shall pay (A) to the Agent those fees
described in and contemplated by the Agreement Regarding Fees with respect to the applicable
Commitment Increase, and (B) to the Arrangers such facility fees as the Revolving Credit Lenders
who are providing an additional Revolving Credit Commitment may require to increase the aggregate
Revolving Credit Commitment, which fees shall, when paid, be fully earned and non-refundable under
any circumstances. The Arrangers shall pay to the Revolving Credit Lenders acquiring the increased
Revolving Credit Commitment certain fees pursuant to their separate agreement; and

               (ii) No Default. On the date any Increase Notice is given and on the date such
increase becomes effective, both immediately before and after the Total Commitment is increased,
there shall exist no Default or Event of Default; and

               (iii) Representations True. The representations and warranties made by the Borrowers
in the Loan Documents or otherwise made by or on behalf of the Borrowers in connection therewith or
after the date thereof shall have been true and correct in all material respects when made and
shall also be true and correct in all material respects on the date of such Increase Notice and on
the date the Total Commitment is increased, both immediately before and after the Total Commitment
is increased; and

               (iv) Additional Documents and Expenses. The Borrowers shall execute and deliver to
Agent and the Revolving Credit Lenders such additional documents (including, without limitation,
amendments to the Security Documents), instruments, certifications and opinions as the Agent may
reasonably require, including, without limitation, a Compliance Certificate, demonstrating
compliance with all covenants set forth in the Loan Documents after giving effect to the increase,
and the Borrowers shall pay the cost of any mortgagee’s title insurance policy or any endorsement
or update thereto or any updated UCC searches, all recording costs and fees, and any and all
intangible taxes or other documentary or mortgage taxes, assessments or charges or any similar
fees, taxes or expenses which are demanded in connection with such increase.

     §2.12 Extension of Revolving Credit Maturity Date. The Borrowers shall have the one-time right and option to extend the Revolving Credit
Maturity Date to March 28, 2014, upon satisfaction or waiver of the following conditions precedent,
which must be satisfied prior to the effectiveness of any extension of the Revolving Credit
Maturity Date:

          (a) Extension Request. The Borrowers shall deliver written notice of such request
(the “Extension Request”) to the Agent not earlier than the date which is ninety (90) days and not
later than the date which is thirty (30) days prior to the Revolving Credit Maturity Date (as
determined without regard to such extension). Any such Extension Request shall be irrevocable and
binding on the Borrowers.

          (b) Payment of Extension Fee. The Borrowers shall pay to the Agent for the
pro rata accounts of the Revolving Credit Lenders in accordance with their
respective Revolving Credit Commitments an extension fee in an amount equal to twenty five (25)
basis points on the Total Commitment in effect on the Revolving Credit Maturity Date (as determined
without

38

 

regard to such extension), which fee shall, when paid, be fully earned and non-refundable
under any circumstances.

          (c) No Default. On the date the Extension Request is given and on the Revolving
Credit Maturity Date (as determined without regard to such extension) there shall exist no Default
or Event of Default.

          (d) Representations and Warranties. The representations and warranties made by the
Borrowers in the Loan Documents or otherwise made by or on behalf of the Borrowers in connection
therewith or after the date thereof shall have been true and correct in all material respects when
made and shall also be true and correct in all material respects on the date the Extension Request
is given and on the Revolving Credit Maturity Date (as determined without regard to such extension)
other than for changes in the ordinary course of business permitted by this Agreement that have not
had a Material Adverse Effect.

          (e) Updated Appraisals. Agent at its option, or at the direction of the Required
Lenders, shall have obtained at Borrowers’ expense updates to existing Appraisals and determined
the current Appraised Values of the Mortgaged Properties.

§3. REPAYMENT OF THE LOANS.

     §3.1 Stated Maturity. The Borrowers promise to pay on the Revolving Credit Maturity Date and there shall become
absolutely due and payable on the Revolving Credit Maturity Date all of the Revolving Credit Loans,
Swing Loans and other Letter of Credit Liabilities outstanding on such date, together with any and
all accrued and unpaid interest thereon.

     §3.2 Mandatory Prepayments. If at any time (including, without limitation, as a result of the application of §2.13) the
sum of the aggregate outstanding principal amount of the Revolving Credit Loans, the Swing Loans
and the Letter of Credit Liabilities exceeds (a) the Total Commitment or (b) the sum of the
Borrowing Base Availability, then the Borrowers shall, within ten (10) Business Days after receipt
of notice from Agent of such occurrence pay the amount of such excess to the Agent for the
respective accounts of the Revolving Credit Lenders, as applicable, for application to the
Revolving Credit Loans as provided in §3.4, together with any additional amounts payable pursuant
to §4.8, except that the amount of any Swing Loans shall be paid solely to the Swing
Loan Lender. In the event there shall have occurred a casualty with respect to any Mortgaged
Property and the Borrowers are required to repay the Loans pursuant to §7.7 or a Taking and the
Borrowers are required to repay the Loans pursuant to a Mortgage or §7.7, the Borrowers shall
prepay the Loans concurrently with the date of receipt by such Borrower or the Agent of any
Insurance Proceeds or Condemnation Proceeds in respect of such casualty or Taking, as applicable,
or as soon thereafter as is reasonably practicable, in the amount required pursuant to the relevant
provisions of §7.7 or such Mortgage.

     §3.3 Optional Prepayments.

          (a) Each Borrower shall have the right, at its election, to prepay the outstanding amount of
the Revolving Credit Loans and Swing Loans, as a whole or in part, at any time without penalty or
premium; provided, that if any prepayment of the outstanding amount of any Revolving Credit
LIBOR Rate Loans pursuant to this §3.3 is made on a date that

39

 

is not the last day of the Interest
Period relating thereto, such prepayment shall be accompanied by the payment of any amounts due
pursuant to §4.8.

          (b) The Borrowers shall give the Agent, no later than 10:00 a.m. (Eastern time) at least three
(3) days prior written notice of any prepayment pursuant to this §3.3, in each case specifying the
proposed date of prepayment of the Loans and the principal amount to be prepaid (provided that (i)
any such notice may be revoked or modified upon one (1) day’s prior notice to the Agent) and (ii)
any such notice may be conditioned upon the consummation of a transaction. Notwithstanding the
foregoing, no prior notice shall be required for the prepayment of any Swing Loan.

     §3.4 Partial Prepayments. Each partial prepayment of the Loans under §3.3 shall be in a minimum amount of $1,000,000
or an integral multiple of $100,000 in excess thereof, shall be accompanied by the payment of
accrued interest on the principal prepaid to the date of payment. Each partial payment under §3.2
and §3.3 shall be applied first to the principal of any Outstanding Swing Loans, then, in the
absence of instruction by the Borrowers, to the principal of Revolving Credit Loans (and with
respect to each category of Loans, first to the principal of Base Rate Loans, and then to the
principal of LIBOR Rate Loans).

     §3.5 Effect of Prepayments. Amounts of the Revolving Credit Loans prepaid under §3.2 and §3.3 prior to the Revolving
Credit Maturity Date may be reborrowed as provided in §2.

§4. CERTAIN GENERAL PROVISIONS.

     §4.1 Conversion Options.

          (a) The Borrowers may elect from time to time to convert any of its outstanding Revolving
Credit Loans to a Revolving Credit Loan of another Type and such Revolving Credit Loans shall
thereafter bear interest as a Base Rate Loan or a LIBOR Rate Loan, as applicable; provided
that (i) with respect to any such conversion of a LIBOR Rate Loan
to a Base Rate Loan, the Borrowers shall give the Agent at least one (1) Business Day’s prior
written notice of such election, and such conversion shall only be made on the last day of the
Interest Period with respect to such LIBOR Rate Loan unless the Borrowers pay Breakage Costs as
required under this Agreement; (ii) with respect to any such conversion of a Base Rate Loan to a
LIBOR Rate Loan, the Borrowers shall give the Agent at least three (3) LIBOR Business Days’ prior
written notice of such election and the Interest Period requested for such Loan, the principal
amount of the Loan so converted shall be in a minimum aggregate amount of $1,000,000 or an integral
multiple of $250,000 in excess thereof and, after giving effect to the making of such Loan, there
shall be no more than ten (10) Revolving Credit LIBOR Rate Loans outstanding at any one time; and
(iii) no Loan may be converted into a LIBOR Rate Loan when any Default or Event of Default has
occurred and is continuing. All or any part of the outstanding Revolving Credit Loans of any Type
may be converted as provided herein, provided that no partial conversion shall result in a
Revolving Credit Base Rate Loan in a principal amount of less than $1,000,000 or an integral
multiple of $100,000 or a Revolving Credit LIBOR Rate Loan in a principal amount of less than
$1,000,000 or an integral multiple of $250,000. On the date on which such conversion is being
made, each Lender shall take such action as is necessary to transfer its Commitment Percentage of
such Loans to its Domestic Lending Office

40

 

or its LIBOR Lending Office, as the case may be. Each
Conversion/Continuation Request relating to the conversion of a Base Rate Loan to a LIBOR Rate Loan
shall be irrevocable by the Borrowers.

          (b) Any LIBOR Rate Loan may be continued as such Type upon the expiration of an Interest
Period with respect thereto by compliance by the Borrowers with the terms of §4.1; provided
that no 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 Base Rate Loan on the last day of the
Interest Period relating thereto ending during the continuance of any Default or Event of Default.

          (c) In the event that the Borrowers do not notify the Agent of their election hereunder with
respect to any LIBOR Rate Loan, such Loan shall be automatically continued at the end of the
applicable Interest Period as a LIBOR Rate Loan for an Interest Period of one month unless such
Interest Period shall be greater than the time remaining until the Revolving Credit Maturity Date,
in which case such Loan shall be automatically converted to a Base Rate Loan at the end of the
applicable Interest Period.

     §4.2 Fees. The Borrowers agree to pay to KeyBank and the Arrangers for their own account certain fees
for services rendered or to be rendered in connection with the Loans as provided pursuant to a fee
letter dated September 28, 2010 between the Borrowers, KeyBank and the Arrangers (the “Agreement
Regarding Fees”).

     §4.3 [Intentionally Omitted.]

     §4.4 Funds for Payments.

          (a) All payments of principal, interest, facility fees, Letter of Credit fees, closing fees
and any other amounts due hereunder or under any of the other Loan Documents shall be made to the
Agent, for the respective accounts of the Lenders and the Agent, as the case may be, at the Agent’s
Head Office, not later than 3:00 p.m. (Eastern time) on the day when due (or such later time as is
acceptable to the Agent in the event of a payment in full of all Loans and a termination of
Commitments hereunder), in each case in lawful money of the United States in immediately available
funds. To the extent not already paid pursuant to the preceding sentence, the Agent is hereby
authorized to charge the accounts of the Borrowers with KeyBank, on the dates when the amount
thereof shall become due and payable, with the amounts of the principal of and interest on the
Loans and all fees, charges, expenses and other amounts owing to the Agent and/or the Lenders
(including the Swing Loan Lender) under the Loan Documents. Subject to the foregoing, all payments
made to Agent on behalf of the Lenders, and actually received by Agent, shall be deemed received by
the Lenders on the date actually received by Agent.

          (b) All payments by the Borrowers 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 now
or hereafter imposed or levied by the United States of America or any political subdivision thereof
or taxing or other authority therein or any jurisdiction from or through which a payment is made by
the Borrowers, excluding any income Taxes, franchise

41

 

Taxes imposed in lieu of income Taxes and any
Taxes imposed by a jurisdiction as a result of any connection between a Lender and such
jurisdiction other than any connection arising solely from executing, delivering, performing its
obligations under, or enforcing any Loan Document (“Non-Excluded Taxes”), unless the Borrowers are
compelled by law to make such deduction or withholding. If any such obligation is imposed upon the
Borrowers with respect to any amount payable by the Borrowers hereunder or under any of the other
Loan Documents, the Borrowers will pay to the Agent, for the account of the Lenders (including the
Swing Loan Lender) or (as the case may be) the 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 or the Agent to receive the same net amount which the Lenders or
the Agent would have received on such due date had no such obligation been imposed upon the
Borrowers; provided, however, that the Borrowers shall not be required to increase
any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are
attributable to such Lender’s failure to comply with the requirements of §4.4(c) or such Lender’s
failure to comply with Sections 1471 through 1474 of the Code or any regulations promulgated
thereunder (the “FATCA”) to establish an exemption from withholding thereunder; (ii) that
are branch profits taxes imposed by the United States or any similar taxes imposed by any other
jurisdiction under the laws of which a Lender is organized or in which its applicable lending
office is located; or (iii) in the case of a Non-U.S. Lender, that are imposed on amounts payable
to such Lender at the time such Lender becomes a party to this Agreement (or designates a new
lending office), except to the extent that such Lender (or its assignor, if any) was entitled, at
the time of designation of a new lending office (or assignment) to receive additional amounts from
the Borrowers with respect to such Non-Excluded Taxes pursuant to this §4.4(b). The Borrowers will
deliver promptly to the Agent certificates or other valid vouchers for all Taxes or other charges
deducted from or paid with respect to payments made by the Borrowers hereunder or under any other
Loan Document. In the event a Lender receives a refund or credit of any Non-Excluded Taxes paid by
the Borrowers pursuant to this section, such Lender will pay to the Borrowers the amount of such
refund or credit (and any interest received with respect thereto) promptly upon receipt
thereof; provided that if at any time thereafter such Lender is required to return such
refund or credit, the Borrowers shall promptly repay to such Lender the amount of such refund or
credit, net of any reasonable incremental additional costs.

          (c) Each Lender that is not a United States Person (as such term is defined in Section
7701(a)(30) of the Code) for U.S. federal income tax purposes (a “Non-U.S. Lender”) , to the extent
such Lender is lawfully able to do so, shall provide the Borrowers on or prior to the Closing Date
(in the case of each Lender listed on the signature pages hereof on the Closing Date) or on or
prior to the date of the Assignment and Acceptance Agreement pursuant to which it becomes a Lender
(in the case of each other Lender), and at such other times as may be necessary in the
determination of the Borrowers, with (x) two (2) original copies of Internal Revenue Service Form
W-8BEN, W-8ECI and/or W-8IMY (or, in each case, any successor forms), properly completed and duly
executed by such Lender, and any other such duly executed form(s) or statement(s) (including
whether such Lender has complied with the FATCA) which may, from time to time, be prescribed by law
and, which, pursuant to applicable provisions of (i) an income tax treaty between the United
States and the country of residence of such Lender, (ii) the Code, or (iii) any applicable rules or
regulations in effect under (i) or (ii) above, establish that such Lender is not subject to
deduction or withholding of United States federal income tax with respect to any payments to such
Lender of principal, interest, fees or other amounts payable

42

 

under any of the Loan Documents, or
(y) if such Lender is not a “bank” or other Person described in Section 881(c)(3) of the Code, a
Certificate Regarding Non-Bank Status together with two (2) original copies of Internal Revenue
Service Form W-8BEN (or any successor form), properly completed and duly executed by such Lender,
and such other documentation required under the Code and requested by the Borrowers to establish
that such Lender is not subject to deduction or withholding of United States federal income tax
with respect to any payments to such Lender of interest payable under any of the Loan Documents.
Each Lender that is a United States Person (as such term is defined in Section 7701(a)(30) of the
Code) for United States federal income tax purposes (a “U.S. Lender”) and is not an exempt
recipient within the meaning of Treasury Regulations Section 1.6049-4(c) shall provide the
Borrowers on or prior to the Closing Date (or, if later, on or prior to the date on which such
Lender becomes a party to this Agreement) two (2) original copies of Internal Revenue Service From
W-9 (or any successor form), properly completed and duly executed by such Lender, certifying that
such U.S. Lender is entitled to an exemption from United States backup withholding tax, or
otherwise prove that it is entitled to such an exemption. Each Lender required to deliver any
forms, certificates or other evidence with respect to United States federal income tax withholding
matters pursuant to this section hereby agrees, from time to time after the initial delivery by
such Lender of such forms, certificates or other evidence, whenever a lapse in time or change in
circumstances renders such forms, certificates or other evidence obsolete or inaccurate in any
material respect, that such Lender shall promptly provide the Borrowers two (2) new original copies
of Internal Revenue Service Form W-9, W-8BEN, W-8ECI and/or W-8IMY (or, in each case, any
successor form), or a Certificate Regarding Non-Bank Status and two (2) original copies of Internal
Revenue Service Form W-8BEN (or any successor form), as the case may be, properly completed and
duly executed by such Lender, and such other documentation required under the Code and requested by
the Borrowers to confirm or establish that such Lender is not subject to deduction or withholding
of United States federal income tax with respect to payments to such Lender
under the Loan Documents, or notify the Borrowers of its inability to deliver any such forms,
certificates or other evidence.

          (d) The obligations of the Borrowers to the Lenders under this Agreement (and of the Revolving
Credit Lenders to make payments to the Issuing Lender with respect to Letters of Credit and to the
Swing Loan Lender with respect to Swing Loans) shall be absolute, unconditional and irrevocable,
and shall be paid and performed strictly in accordance with the terms of this Agreement, under all
circumstances whatsoever, including, without limitation, the following circumstances: (i) any lack
of validity or enforceability of this Agreement, any Letter of Credit or any of the other Loan
Documents; (ii) any improper use which may be made of any Letter of Credit or any improper acts or
omissions of any beneficiary or transferee of any Letter of Credit in connection therewith; (iii)
the existence of any claim, set-off, defense or any right which the Borrowers or any of their
Subsidiaries or Affiliates may have at any time against any beneficiary or any transferee of any
Letter of Credit (or persons or entities for whom any such beneficiary or any such transferee may
be acting) or the Lenders (other than the defense of payment to the Lenders in accordance with the
terms of this Agreement) or any other person, whether in connection with any Letter of Credit, this
Agreement, any other Loan Document, or any unrelated transaction; (iv) any draft, demand,
certificate, statement or any other documents presented under any Letter of Credit proving to be
insufficient, forged, fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect whatsoever; (v) any breach of any agreement between Borrowers or any of
their Subsidiaries or Affiliates and

43

 

any beneficiary or transferee of any Letter of Credit; (vi)
any irregularity in the transaction with respect to which any Letter of Credit is issued, including
any fraud by the beneficiary or any transferee of such Letter of Credit; (vii) payment by the
Issuing Lender under any Letter of Credit against presentation of a sight draft, demand,
certificate or other document which does not comply with the terms of such Letter of Credit,
provided that such payment shall not have constituted gross negligence or willful
misconduct on the part of the Issuing Lender as determined by a court of competent jurisdiction
after the exhaustion of all applicable appeal periods; (viii) any non-application or misapplication
by the beneficiary of a Letter of Credit of the proceeds of such Letter of Credit; (ix) the
legality, validity, form, regularity or enforceability of the Letter of Credit; (x) the failure of
any payment by Issuing Lender to conform to the terms of a Letter of Credit (if, in Issuing
Lender’s good faith judgment, such payment is determined to be appropriate); (xi) the surrender or
impairment of any security for the performance or observance of any of the terms of any of the Loan
Documents; (xii) the occurrence of any Default or Event of Default; and (xiii) any other
circumstance or happening whatsoever, whether or not similar to any of the foregoing,
provided that such other circumstances or happenings shall not have been the result of
gross negligence or willful misconduct on the part of the Issuing Lender or the Swing Loan Lender,
as applicable as determined by a court of competent jurisdiction after the exhaustion of all
applicable appeal periods.

     §4.5 Computations. All computations of interest on the Loans (other than Base Rate Loans at the prime rate,
which shall be based on a 365/366-day year as the case may be) 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, 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 Loans and Letter of Credit Liabilities as reflected on the records of the Agent from
time to time shall be considered prima facie evidence of such amount absent manifest error.

     §4.6 Suspension of LIBOR Rate Loans. In the event that, prior to the commencement of any Interest Period relating to any LIBOR
Rate Loan, the Agent shall determine that adequate and reasonable methods do not exist for
ascertaining LIBOR for such Interest Period, or the Agent shall reasonably determine that LIBOR
will not accurately and fairly reflect the cost of the Lenders making or maintaining LIBOR Rate
Loans for such Interest Period, the Agent shall forthwith give notice of such determination (which
shall be conclusive and binding on the Borrowers and the Lenders absent manifest error) to the
Borrowers and the Lenders. In such event (a) any Loan Request with respect to a LIBOR Rate Loan
shall be automatically withdrawn and shall be deemed a request for a Base Rate Loan and (b) each
LIBOR Rate Loan will automatically, on the last day of the then current Interest Period applicable
thereto, become a Base Rate Loan, and the obligations of the Lenders to make LIBOR Rate Loans shall
be suspended until the Agent determines that the circumstances giving rise to such suspension no
longer exist, whereupon the Agent shall so notify the Borrowers and the Lenders.

     §4.7 Illegality. Notwithstanding any other provisions herein, if after the date hereof any law, regulation,
treaty or directive shall be enacted or the interpretation or application thereof shall make it
unlawful, or any central bank or other governmental authority having jurisdiction

44

 

over a Lender or
its LIBOR Lending Office shall assert that it is unlawful, for any Lender to make or maintain LIBOR
Rate Loans, such Lender shall forthwith give notice of such circumstances to the Agent and the
Borrowers and thereupon (a) the commitment of the Lenders to make LIBOR Rate Loans shall forthwith
be suspended and (b) the LIBOR Rate Loans then outstanding shall be converted automatically to 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. Notwithstanding the foregoing, before giving such
notice, the applicable Lender shall designate a different lending office if such designation will
void the need for giving such notice and will not, in the reasonable judgment of such Lender, be
otherwise materially disadvantageous to such Lender or increase any costs payable by Borrowers
hereunder.

     §4.8 Additional Interest. If any LIBOR Rate Loan or any portion thereof is repaid or is converted to a Base Rate Loan
for any reason on a date which is prior to the last day of the Interest Period applicable to such
LIBOR Rate Loan, or if repayment of the Loans has been accelerated as provided in §12.1, the
Borrowers will pay to the Agent upon demand for the account of the applicable Lenders in accordance
with their respective Commitment Percentages (or to the Swing Loan Lender with respect to a Swing
Loan), in addition to any amounts of interest otherwise payable hereunder, the Breakage Costs.
Borrowers understand, agree and acknowledge the following: (i) no Lender has any obligation to
purchase, sell and/or match funds in connection with the use of LIBOR as a
basis for calculating the rate of interest on a LIBOR Rate Loan; (ii) LIBOR is used merely as
a reference in determining such rate; and (iii) Borrowers have accepted LIBOR as a reasonable and
fair basis for calculating such rate and any Breakage Costs. Borrowers further agree to pay the
Breakage Costs, if any, whether or not a Lender elects to purchase, sell and/or match funds.

     §4.9
Additional Costs, Etc. Notwithstanding anything herein to the contrary, if after the date hereof any 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
charged with the administration or the interpretation thereof and directives and instructions at
any time or from time to time hereafter made upon or otherwise issued to any Lender or the 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 Agent to any tax, levy, impost, duty, charge, fee, deduction or
withholding of any nature with respect to this Agreement, the other Loan Documents, such Lender’s
Commitment, a Letter of Credit or the Loans (other than taxes based upon or measured by the gross
receipts, income or profits of such Lender or the Agent or its franchise tax), or

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

          (c) impose or increase or render applicable any special deposit, reserve, assessment,
liquidity, capital adequacy or other similar requirements (whether or not having the force of law
and which are not already reflected in any amounts payable by Borrowers

45

 

hereunder) against assets
held by, or deposits in or for the account of, or loans by, or commitments of an office of any
Lender, or

          (d) impose on any Lender or the Agent any other conditions or requirements with respect to
this Agreement, the other Loan Documents, the Loans, such Lender’s Commitment, a Letter of Credit
or any class of loans 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, the Letters of Credit or such Lender’s Commitment, or

               (ii) to reduce the amount of principal, interest or other amount payable to any Lender or the
Agent hereunder on account of such Lender’s Commitment or any of the Loans or the Letters of
Credit, or

               (iii) to require any Lender or the Agent to make any payment or to forego any interest or
other sum payable hereunder, the amount of which payment or foregone interest or other sum is
calculated by reference to the gross amount of any sum receivable or
deemed received by such Lender or the Agent from the Borrowers hereunder, then, and in each
such case, the Borrowers will (and as to clauses (a) and (b) above, subject to the provisions of
Section §4.4), within thirty (30) days of demand made by such Lender or (as the case may be) the
Agent at any time and from time to time and as often as the occasion therefor may arise, pay to
such Lender or the Agent such additional amounts as such Lender or the Agent shall determine in
good faith to be sufficient to compensate such Lender or the Agent for such additional cost,
reduction, payment or foregone interest or other sum. For the avoidance of doubt, the provisions
of this §4.9 shall not apply with respect to Taxes, which shall be governed by §4.4(b) and §4.4(c).

     §4.10 Capital Adequacy. If after the date hereof any Lender determines that (a) the adoption of or change in any
law, rule or regulation regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by any governmental authority charged with the
administration thereof, or (b) compliance by such Lender or its parent bank holding company with
any directive of any such entity regarding capital adequacy, has the effect of reducing the return
on such Lender’s or such holding company’s capital as a consequence of such Lender’s commitment to
make Loans or participate in Letters of Credit hereunder to a level below that which such Lender or
holding company could have achieved but for such adoption, change or compliance (taking into
consideration such Lender’s or such holding company’s then existing policies with respect to
capital adequacy and assuming the full utilization of such entity’s capital) by any amount deemed
by such Lender to be material, then such Lender may notify the Borrowers thereof. The Borrowers
agree to pay to such Lender the amount of such reduction in the return on capital as and when such
reduction is determined, upon presentation by such Lender of a statement of the amount setting
forth the Lender’s calculation thereof. In determining such amount, such Lender may use any
reasonable averaging and attribution methods generally applied by such Lender.

46

 

     §4.11 Breakage Costs. Borrowers shall pay all Breakage Costs required to be paid by them pursuant to this
Agreement and incurred from time to time by any Lender within fifteen (15) days from receipt of
written notice from Agent.

     §4.12 Default Interest; Late Charge. Following the occurrence and during the continuance of any Event of Default, and regardless
of whether or not the Agent or the Lenders shall have accelerated the maturity of the Loans, all
Loans shall bear interest payable on demand at a rate per annum equal to three percent (3.0%) above
the interest rate that would otherwise be in effect hereunder (the “Default Rate”), until such
amount shall be paid in full (after as well as before judgment), and the fee payable with respect
to Letters of Credit shall be increased to a rate equal to three percent (3.0%) above the Letter of
Credit fee that would otherwise be applicable to such time, or if any of such amounts shall exceed
the maximum rate permitted by law, then at the maximum rate permitted by law. In addition, the
Borrowers shall pay a late charge equal to three percent (3.0%) of any amount of interest and/or
principal payable on the Loans or any other amounts payable hereunder
or under the other Loan Documents, which is not paid by the Borrowers within ten (10) days of
the date when due.

     §4.13 Certificate. A certificate setting forth any amounts payable pursuant to §4.8, §4.9, §4.10, §4.11 or
§4.12 and a reasonably detailed explanation of such amounts which are due, submitted by any Lender
or the Agent to the Borrowers, shall be presumptively correct in the absence of manifest error.

     §4.14 Limitation on Interest. Notwithstanding anything in this Agreement or the other Loan Documents to the contrary, all
agreements between or among the Borrowers, the Lenders and the Agent, whether now existing or
hereafter arising and whether written or oral, are hereby limited so that in no contingency,
whether by reason of acceleration of the maturity of any of the Obligations or otherwise, shall the
interest contracted for, charged or received by the Lenders exceed the maximum amount permissible
under applicable law. If, from any circumstance whatsoever, interest would otherwise be payable to
the Lenders in excess of the maximum lawful amount, the interest payable to the Lenders shall be
reduced to the maximum amount permitted under applicable law; and if from any circumstance the
Lenders shall ever receive anything of value deemed interest by applicable law in excess of the
maximum lawful amount, an amount equal to any excessive interest shall be applied to the reduction
of the principal balance of the Obligations and to the payment of interest or, if such excessive
interest exceeds the unpaid balance of principal of the Obligations, such excess shall be refunded
to the Borrowers. All interest paid or agreed to be paid to the Lenders shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread throughout the full
period until payment in full of the principal of the Obligations (including the period of any
renewal or extension thereof) so that the interest thereon for such full period shall not exceed
the maximum amount permitted by applicable law. This Section shall control all agreements between
or among the Borrowers, the Lenders and the Agent.

     §4.15 Certain Provisions Relating to Increased Costs and Non-Funding Lenders. If a Lender gives notice of the existence of the circumstances set forth in §4.7 or any
Lender requests compensation for any losses or costs to be reimbursed pursuant to any one or more
of the provisions of §4.4(b) (as a result of the imposition of U.S. withholding taxes on amounts
paid to such Lender under this Agreement), §4.9 or §4.10, then, such Lender, as applicable, shall
use

47

 

reasonable efforts in a manner consistent with such institution’s practice in connection with
loans like the Loan of such Lender to eliminate, mitigate or reduce amounts that would otherwise be
payable by Borrowers under the foregoing provisions, provided that such action would not be
otherwise materially prejudicial to such Lender, including, without limitation, by designating
another of such Lender’s offices, branches or affiliates; the Borrowers agreeing to pay all
reasonably incurred costs and expenses incurred by such Lender in connection with any such action.
Notwithstanding anything to the contrary contained herein, if no Default or Event of Default shall
have occurred and be continuing, and if any Lender (a) has given notice of the existence of the
circumstances set forth in §4.7 or has requested payment or
compensation for any losses or costs to be reimbursed pursuant to any one or more of the
provisions of §4.4(b) (as a result of the imposition of U.S. withholding taxes on amounts paid to
such Lender under this Agreement), §4.9 or §4.10 and following the request of Borrowers has been
unable to take the steps described above to mitigate such amounts (each, an “Affected Lender”) or
(b) has failed to make available to Agent its pro rata share of any Loan or participation in a
Letter of Credit or Swing Loan and such failure has not been cured (a “Non-Funding Lender”), then,
within thirty (30) days after such notice or request for payment or compensation or failure to
fund, as applicable, Borrowers shall have the right as to such Affected Lender or Non-Funding
Lender, as applicable, to be exercised by delivery of written notice delivered to the Agent and the
Affected Lender or Non-Funding Lender, as applicable, to elect to cause the Affected Lender or
Non-Funding Lender, as applicable, to transfer its Commitment. The Agent shall promptly notify the
remaining Lenders that each of such Lenders shall have the right, but not the obligation, to
acquire a portion of the Commitment, pro rata based upon their relevant Commitment Percentages, of
the Affected Lender or Non-Funding Lender, as applicable (or if any of such Lenders does not elect
to purchase its pro rata share, then to such remaining Lenders in such proportion as approved by
the Agent). In the event that the Lenders do not elect to acquire all of the Affected Lender’s or
Non-Funding Lender’s Commitment, then the Agent shall endeavor to obtain a new Lender to acquire
such remaining Commitment. Upon any such purchase of the Commitment of the Affected Lender or
Non-Funding Lender, as applicable, the Affected Lender’s or Non-Funding Lender’s interest in the
Obligations and its rights hereunder and under the Loan Documents shall terminate at the date of
purchase, and the Affected Lender or Non-Funding Lender, as applicable, shall promptly execute all
documents reasonably requested to surrender and transfer such interest. The purchase price for the
Affected Lender’s or Non-Funding Lender’s Commitment shall equal any and all amounts outstanding
and owed by Borrowers to the Affected Lender or Non-Funding Lender, as applicable, including
principal, prepayment premium or fee, and all accrued and unpaid interest or fees.

     §5. COLLATERAL SECURITY.

     §5.1 Collateral. The Obligations shall be secured by a perfected first priority lien and security interest
to be held by the Agent for the benefit of the Lenders on the Collateral, pursuant to the terms of
the Security Documents.

     §5.2 Appraisals; Adjusted Value.

          (a) Upon Borrowers’ request, which request may not be made more often than one (1) time
annually, Agent shall obtain current Appraisals of each of the Mortgaged Properties. Additionally,
in the event that Borrowers elect to extend the Revolving Credit Maturity Date as

48

 

provided in §2.12
or at Agent’s option, or at the direction of the Required Lenders, to be exercised not more
frequently than annually, or to the extent requested by Borrowers, the Agent may obtain current
Appraisals of each of the Mortgaged Properties. In any such case, such Appraisals will be ordered
by Agent in order to determine the current Appraised Value of the Mortgaged Properties and other
Real Estate, as applicable, and the Borrowers shall pay to Agent within thirty (30) days of demand
all reasonable out-of-pocket costs of such Appraisals.

          (b) Notwithstanding the provisions of §5.2(a), the Agent may, for the purpose of determining
the current Appraised Value of the Mortgaged Properties and other Real Estate, as applicable,
obtain new Appraisals or an update to existing Appraisals with respect to such property, or any of
them, as the Agent shall determine (i) at any time that the regulatory requirements of any Lender
generally applicable to real estate loans of the category made under this Agreement as reasonably
interpreted by such Lender shall explicitly require more frequent Appraisals, or (ii) at any time
during the continuance of an Event of Default, or (iii) with the consent of the Required Lenders,
if the Agent reasonably believes that there has been a material change with respect to any such
property including, without limitation, a material change in the market in which any such property
is located which may affect the value of such property. The reasonable out-of-pocket expense of
such Appraisals and/or updates performed pursuant to this §5.2(b) shall be borne by the Borrowers
and payable to Agent within thirty (30) days of demand; provided the Borrowers shall not be
obligated to pay for an Appraisal of a property obtained pursuant to this §5.2(b) more often than
once annually. Upon receipt, Agent shall provide a copy of the Appraisal to Borrower.

          (c) The Borrowers acknowledge that the Agent has the right to approve any Appraisal performed
pursuant to this Agreement. The Borrowers further agree that the Lenders and Agent do not make any
representations or warranties with respect to any such Appraisal and shall have no liability as a
result of or in connection with any such Appraisal for statements contained in such Appraisal,
including without limitation, the accuracy and completeness of information, estimates, conclusions
and opinions contained in such Appraisal, or variance of such Appraisal from the fair value of such
property that is the subject of such Appraisal given by the local tax assessor’s office, or the
Borrowers’ idea of the value of such property.

     §5.3 Addition of Mortgaged Properties.

          (a) After the Closing Date, Parent Borrower shall have the right, subject to the consent of
the Agent and the Required Lenders (which consent shall not be unreasonably withheld) and the
satisfaction by Parent Borrower of the conditions set forth in this §5.3, to add Potential
Collateral to the Collateral. Parent Borrower from time to time after the Closing Date may also
request that certain Real Estate of one or more Subsidiary Borrowers (collectively, the “Subsidiary
Borrower Collateral”) be included as a Mortgaged Property for the purpose of increasing the
Borrowing Base Availability. In the event Parent Borrower desires to add additional Potential
Collateral or Subsidiary Borrower Collateral as aforesaid, Parent Borrower shall provide written
notice to the Agent of such request (which the Agent shall promptly furnish to the Lenders),
together with all documentation and other information required to permit the Agent to determine
whether such Real Estate is Eligible Real Estate. Thereafter, the Agent shall have ten (10)
Business Days from the date of the receipt of such documentation and other information to advise
Parent Borrower whether the Required Lenders consent to the acceptance

49

 

of such Subsidiary Borrower
Collateral or Potential Collateral. If a Lender shall fail to respond to Agent within such ten
(10) Business Day period, such Lender shall be deemed to have approved such proposed Subsidiary
Borrower Collateral or Potential Collateral. Notwithstanding the foregoing, no Subsidiary Borrower
Collateral or Potential Collateral shall be included as Collateral unless and until the following
conditions precedent shall have been satisfied:

               (i) such Subsidiary Borrower Collateral or Potential Collateral shall be Eligible Real Estate;

               (ii) the owner of any Subsidiary Borrower Collateral (and any indirect owner of such
Subsidiary Borrower) shall have executed a Joinder Agreement and satisfied the conditions of §5.5;

               (iii) Parent Borrower or the owner of the Subsidiary Borrower Collateral or Potential
Collateral, as applicable, shall have executed and delivered to the Agent all Eligible Real Estate
Qualification Documents (which may include an assignment of interests with respect to any direct or
indirect interests in the owner of such Subsidiary Borrower Collateral), all of which instruments,
documents or agreements shall be in form and substance reasonably satisfactory to the Agent;

               (iv) after giving effect to the inclusion of such Subsidiary Borrower Collateral or Potential
Collateral, each of the representations and warranties made by or on behalf of the Borrowers or any
of their respective Subsidiaries contained in this Agreement, the other Loan Documents or in any
document or instrument delivered pursuant to or in connection with this Agreement shall be true in
all material respects both as of the date as of which it was made and shall also be true as of the
time of the replacement or addition of Mortgaged Properties, with the same effect as if made at and
as of that time (it being understood and agreed that any representation or warranty which by its
terms is made as of a specified date shall be required to be true and correct only as of such
specified date), and no Default or Event of Default shall have occurred and be continuing, and the
Agent shall have received a certificate of Parent Borrower to such effect; and

               (v) the Agent shall have consented to, and Agent shall have received the prior written consent
of the Required Lenders to, the inclusion of such Real Estate as a Mortgaged Property.

     Notwithstanding the foregoing, in the event such Subsidiary Borrower Collateral or Potential
Collateral does not qualify as Eligible Real Estate, so long as the conditions set forth in clauses
(ii), (iii) and (iv) of this §5.3 have been satisfied, such Subsidiary Borrower Collateral or
Potential Collateral shall be included as Collateral so long as the Agent shall have received the
prior written consent of each of the Lenders to the inclusion of such Real Estate as a Mortgaged
Property.

          (b) Parent Borrower may, at its option, obtain preliminary approval of the Required Lenders of
Subsidiary Borrower Collateral or Potential Collateral by delivering to the

50

 

Agent and each of the
Lenders the following with respect to such Subsidiary Borrower Collateral or Potential Collateral:

               (i) a physical description of the Real Estate;

               (ii) current rent rolls, historic operating statements and operating and capital budgets (if
available to Parent Borrower), and projected operating and near-term capital expenditure budgets
for such Real Estate reasonably satisfactory to the Required Lenders;

               (iii) a current environmental report, a current engineering report and similar information
reasonably satisfactory to the Required Lenders; and

               (iv) a certification to the knowledge of Parent Borrower that such Real Estate will satisfy
(or is anticipated to satisfy upon the acceptance of such Real Estate as Collateral) each of the
other conditions to the acceptance of Real Estate as Collateral. The Required Lenders shall have
ten (10) Business Days following receipt of all of the foregoing items to grant or deny preliminary
approval for such proposed Subsidiary Borrower Collateral or Potential Collateral. If a Lender
shall fail to respond within such ten (10) Business Day period, such Lender shall be deemed to have
approved such proposed Subsidiary Borrower Collateral or Potential Collateral. Agent shall notify
Parent Borrower if and when the Required Lenders have granted such preliminary approval. In the
event that the Required Lenders grant such preliminary approval, Parent Borrower may satisfy the
remaining requirements to the acceptance of such Collateral as provided in §5.3(a). Such Real
Estate shall not be included in the calculation of the Borrowing Base Availability until the
requirements of §5.3(a) are satisfied.

     §5.4 Release of Mortgaged Property. Provided no Default or Event of Default shall have occurred hereunder and be continuing (or
would exist immediately after giving effect to the transactions contemplated by this §5.4), upon
reasonable approval by the Agent if the Removal Conditions are satisfied, and otherwise upon
reasonable approval by the Required Lenders, the Agent shall release a Mortgaged Property from the
lien or security title of the Security Documents encumbering the same in connection with a sale,
other disposition or refinance upon the request of Parent Borrower subject to and upon the
following terms and conditions:

          (a) Parent Borrower shall deliver to the Agent written notice of its desire to obtain such
release no later than ten (10) days prior to the date on which such release is to be effected;

          (b) Parent Borrower shall submit to the Agent with such request a Compliance Certificate
prepared using the financial statements of Parent Borrower most recently provided or required to be
provided to the Agent under §6.4 or §7.4 adjusted in the best good faith estimate of Parent
Borrower to give effect to the proposed release and demonstrating that no Default or Event of
Default with respect to the covenants referred to therein shall exist after giving effect to such
release;

          (c) all release documents to be executed by the Agent shall be in form and substance
reasonably satisfactory to the Agent;

51

 

          (d) Parent Borrower shall pay all reasonable costs and expenses of the Agent in connection
with such release, including without limitation, reasonable attorney’s fees;

          (e) Parent Borrower shall pay to the Agent for the account of the Lenders a release price,
which payment shall be applied to reduce the outstanding principal balance of the Loans as provided
in §3.4, in an amount equal to the amount necessary, if any, to reduce the outstanding principal
balance of the Loans so that no violation of the covenant set forth in §9.1 shall occur; and

          (f) without limiting or affecting any other provision hereof, any release of a Mortgaged
Property will not cause the Borrowers to be in violation of the covenants set forth in §9.6.

Notwithstanding the foregoing, it shall require the consent of all the Lenders to approve any
requested release of the Mortgaged Property located at 2901 Coronado Drive, Santa Clara,
California.

     §5.5 Additional Subsidiary Borrowers. In the event that Parent Borrower shall request that certain Real Estate of a Subsidiary of
Parent Borrower be included as a Mortgaged Property as contemplated by §5.3 and such Real Estate is
approved for inclusion as a Mortgaged Property in accordance with the terms hereof, Parent Borrower
shall cause each such Subsidiary (and any entity having an interest in such Subsidiary of Parent
Borrower) to execute and deliver to Agent a Joinder Agreement, and such Subsidiary (and any such
entity) shall become a Subsidiary Borrower hereunder. Each such Subsidiary shall be specifically
authorized, in accordance with its respective organizational documents, to be a Borrower hereunder
and to execute such Security Documents as Agent may require. Parent Borrower shall further cause
all representations, covenants and agreements in the Loan Documents with respect to Borrowers to be
true and correct with respect to each such Subsidiary. In connection with the delivery of such
Joinder Agreement, Parent Borrower shall deliver to the Agent such organizational agreements,
resolutions, consents, opinions and other documents and instruments as the Agent may reasonably
require.

     §5.6 Release of Certain Subsidiary Borrowers. In the event that all Mortgaged Properties owned by a Subsidiary Borrower shall have been
released as Collateral for the Obligations in accordance with the terms of this Agreement, then
such Subsidiary Borrower shall be released by Agent from liability under this Agreement.

     §5.7 Release of Collateral. Upon the refinancing or repayment of the Obligations in full and termination of the
obligation to provide additional Loans or Letters of Credit to Borrowers, then the Agent shall be
entitled to release the Collateral from the lien and security interest of the Security Documents
and to release the Borrowers.

§6. REPRESENTATIONS AND WARRANTIES.

     The Borrowers represent and warrant to the Agent and the Lenders as follows, each as of the
Closing Date hereof, and as of the date of a request for a funding of any Loan hereunder; provided
however, to the extent such representation and warranty is not true or accurate as of the

52

 

date of a
request for funding of any Loan hereunder, such shall not have, or be deemed to have, any Material
Adverse Effect.

     §6.1 Corporate Authority, Etc.

          (a) Incorporation; Good Standing. Parent Borrower is a Delaware limited partnership
duly organized pursuant to its articles of organization or formation filed with the Delaware
Secretary of State, and is validly existing and in good standing under the laws of Delaware.
Parent Borrower (i) has all requisite power to own its property and conduct its business as now
conducted and as presently contemplated, and (ii) is in good standing and is duly authorized to do
business in the jurisdictions where the Mortgaged Properties owned or leased by it are located and
in each other jurisdiction where a failure to be so qualified in such other jurisdiction could have
a Material Adverse Effect.

          (b) Subsidiaries. Each of the Subsidiary Borrowers and each of the Subsidiaries of
the Borrowers (i) is a corporation, limited partnership, general partnership, limited liability
company or trust duly organized under the laws of its State of organization and is validly existing
and in good standing under the laws thereof, (ii) has all requisite power to own its property and
conduct its business as now conducted and as presently contemplated and (iii) is in good standing
and is duly authorized to do business in each jurisdiction where a Mortgaged Property owned or
leased by it is located (to the extent required by applicable law) and in each other jurisdiction
where a failure to be so qualified could have a Material Adverse Effect.

          (c) Authorization. The execution, delivery and performance of this Agreement and the

director or such employee or, to the knowledge of the Borrowers, any corporation, partnership,
trust or other entity in which any partner, officer, trustee, director, or any such employee has a
substantial interest or is an officer, director, trustee or partner, which are on terms less
favorable to the Borrowers than those that would be obtained in a comparable arms-length
transaction.

and each ERISA Affiliate has fulfilled its obligation, if any, under the minimum funding standards

reason to believe that the Agent and the Lenders may not rely on the accuracy thereof) or (b)
budgets, projections and other forward-looking speculative information prepared in good faith by
the Borrowers (except to the extent the related assumptions were when made manifestly
unreasonable).

credit for the purpose of purchasing or carrying any “margin security” or “margin stock” as such
terms are used in Regulations T, U and X of the Board of Governors of the Federal Reserve System,
12 C.F.R. Parts 220, 221 and 224.

     §6.20 Environmental Compliance. Except as set forth on Schedules 6.20(d) or as specifically set forth in the

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

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 in the case of
clauses (i) through (iii) above could reasonably be expected to have a Material Adverse Effect.

          (c) To the knowledge of the Borrowers, (i) no portion of the Real Estate is used for the
handling, processing, storage or disposal of Hazardous Substances except in compliance with
applicable Environmental Laws, and no underground tank or other underground storage receptacle for

expected to have a Material Adverse Effect; (iv) there have been no Releases on, upon, from or into
any real property in the vicinity of any of the Real Estate which, through soil or groundwater
contamination, may have come to be located on, and which could be reasonably anticipated to have a

          (d) Except as set forth on Schedule 6.20(d) or for such matters that shall be complied
with as of the Closing Date, by virtue of the transactions set forth herein and contemplated
hereby, or as a condition to the recording of the Mortgages or to the effectiveness of any other
transactions contemplated hereby, none of the Borrowers, their respective Subsidiaries nor the Real
Estate will become subject to any applicable Environmental Law requiring the performance of
environmental site assessments, or the removal or remediation of Hazardous Substances, or the
giving of notice to any governmental agency or the recording or delivery to other Persons of an
environmental disclosure document or statement pursuant to applicable Environmental Laws.

58

 

          (e) There are no existing or closed sanitary or solid waste landfills, or hazardous waste
treatment, storage or disposal facilities on or, to Borrowers’ actual knowledge, affecting the Real
Estate except where such existence could not reasonably be expected to have a Material Adverse
Effect.

          (f) The Borrowers have not received any written notice from any party that any use, operation,
or condition of the Borrower’s business on any Real Estate has caused any adverse condition on any
other property that could reasonably be expected to result in a claim under applicable

knowledge of any existing facts or circumstances that could reasonably be expected to form the
basis for such a claim.

     §6.21 Subsidiaries; Organizational Structure. Schedule 6.21(a) sets forth, as of the date hereof and after giving effect to the
reorganization previously disclosed to the Agent, all of the Subsidiaries of Parent Borrower, the
form and jurisdiction of organization of each of the Subsidiaries, and the owners of the direct and
indirect ownership interests therein. Schedule 6.21(b) sets forth, as of the date hereof,
all of the Unconsolidated Subsidiaries of Parent Borrower and its Subsidiaries, the form and
jurisdiction of organization of each of the Unconsolidated Subsidiaries, Parent Borrower’s or its
Subsidiary’s ownership interest therein and the other owners of the applicable Unconsolidated
Subsidiary. No Person owns any legal, equitable or beneficial interest in any of the Persons set
forth on Schedules 6.21(a) and 6.21(b) except as set forth on such Schedules.

     §6.22 Leases. The Borrowers have delivered to the Agent true and complete copies of the Leases and any
amendments thereto relating to each Mortgaged Property required to be delivered as a part of the
Eligible Real Estate Qualification Documents as of the date hereof. An accurate and complete Rent
Roll in all material respects as of the date of inclusion of each Mortgaged Property in the
Collateral with respect to all Leases of any portion of the Mortgaged Property has been provided to
the Agent. The Leases previously delivered to Agent as described in the preceding sentence
constitute as of the date thereof the sole agreements relating to leasing or licensing of space at
such Mortgaged Property and in the Building relating thereto. No tenant under any Lease is
entitled to any free rent, partial rent, rebate of rent payments, credit, offset or deduction in
rent, including, without limitation, lease support payments or lease buy-outs, except as reflected
in such Leases or such Rent Roll. Except as set forth in Schedule 6.22, the Leases
reflected therein are, as of the date of inclusion of the applicable Mortgaged Property in the
Collateral, in full force and effect in accordance with their respective terms, without any payment
default or any other material default thereunder, nor are there any defenses, counterclaims,
offsets, concessions or rebates available to any tenant thereunder, and except as reflected in
Schedule 6.22, no Borrower has given or made, any notice of any payment or other material
default, or any claim, which remains uncured or unsatisfied, with respect to any of the Leases, and
to the best of the knowledge and belief of the Borrowers, there is no basis for any such claim or
notice of default by any tenant which would result in a Material Adverse Effect. Borrower knows of
no condition which with the giving of notice or the passage of time or both would constitute a
default on the part of any tenant with respect to the material terms under a Lease or of the
respective Borrower as landlord under the Lease. No security deposit or advance rental or fee
payment has been made by any lessee or licensor under the Leases except as may be specifically
designated in the copies of the Leases furnished to the Agent. No property other than

59

 

the Mortgaged
Property which is the subject of the applicable Lease is necessary to comply with the requirements
(including, without limitation, parking requirements) contained in such Lease.

     §6.23 Property. Except as set forth in Schedule 6.23 or as set forth in the written engineer reports
provided to Agent on or before the date hereof, all of the Mortgaged Properties, and all major
building systems located thereon, are structurally sound, in good condition and working order and
free from material defects, subject to ordinary wear and tear, except for such portion of such Real
Estate which is not occupied by any tenant and which may not be in final working order pending
final build-out of such space. All of the other Real Estate of the Borrowers and their respective
Subsidiaries is structurally sound, in good condition and working order, subject to ordinary wear
and tear, except for such portion of such Real Estate which is not occupied by any tenant and where
such defects have not had and could not reasonably be expected to have a Material Adverse Effect.
Each of the Mortgaged Properties, and the use and operation thereof, is in material compliance with
all applicable federal and state law and governmental regulations and any local ordinances, orders
or regulations, including without limitation, laws, regulations and ordinances relating to zoning,
building codes, subdivision, fire protection, health, safety, handicapped access, historic
preservation and protection, wetlands, tidelands, and Environmental Laws except in cases that would
not reasonably cause a Material Adverse Effect. All water, sewer, electric, gas, telephone and
other utilities necessary for the use and operation of the
Mortgaged Property are installed to the property lines of the Mortgaged Property through
dedicated public rights of way or through perpetual private easements with respect to which the
applicable Mortgage creates a valid and enforceable first lien subject to Permitted Liens and,
except in the case of drainage facilities, are connected to the Building located thereon with valid
permits and are adequate to service the Building in compliance with applicable law. The streets
abutting the Mortgaged Property are dedicated and accepted public roads, to which the Mortgaged
Property has direct access or are perpetual private ways (with direct access to public roads) to
which the Mortgaged Property has direct access and with respect to which the applicable Mortgage
creates a valid and enforceable first lien. There are no unpaid or outstanding real estate or
other taxes or assessments on or against any of the Mortgaged Properties which are payable by any
Borrower (except only real estate or other taxes or assessments, that are not yet delinquent or are
being protested as permitted by this Agreement). Each Mortgaged Property is separately assessed
for purposes of real estate tax assessment and payment. There are no unpaid or outstanding real
estate or other taxes or assessments on or against any other property of the Borrowers or any of
their respective Subsidiaries which are payable by any of such Persons in any material amount
(except only real estate or other taxes or assessments, that are not yet delinquent or are being
protested as permitted by this Agreement). There are no pending, or to the knowledge of Borrowers
threatened or contemplated, eminent domain proceedings against any of the Mortgaged Properties.
None of the Mortgaged Properties is now damaged in any material respects as a result of any fire,
explosion, accident, flood or other casualty. None of the Borrowers has received any outstanding
notice from any insurer or its agent requiring performance of any work with respect to any of the
Mortgaged Properties or canceling or threatening to cancel any policy of insurance, and each of the
Mortgaged Properties complies with the material requirements of all of the Borrowers’ insurance
carriers. Except as listed on Schedule 6.23, the Borrowers have no Management Agreements
for any of the Mortgaged Properties. No person or entity has any right or option to acquire any
Mortgaged Property or any Building thereon or any portion thereof or interest therein, except for
certain tenants pursuant to the terms of their Leases with Subsidiary Borrowers.

60

 

     §6.24 Brokers. None of the Borrowers nor any of their respective Subsidiaries has engaged or otherwise
dealt with any broker, finder or similar entity in connection with this Agreement or the Loans
contemplated hereunder.

     §6.25 Other Debt. None of the Borrowers is in default of the payment of any Indebtedness or the performance
of any material obligation under any related agreement, mortgage, deed of trust, security
agreement, financing agreement or indenture to which any of them is a party involving Indebtedness
individually or in the aggregate in excess of $25,000,000. None of the Borrowers is a party to or
bound by any agreement, instrument or indenture that may require the subordination in right or time
or payment of any of the Obligations to any other indebtedness or obligation of any Borrower.
Schedule 6.25 hereto sets forth all agreements, mortgages, deeds of trust, financing
agreements or other material agreements binding upon the Borrowers or their respective properties
and entered into by the Borrowers as of the date of this Agreement with
respect to any Indebtedness of the Borrowers, and the Borrowers have provided the Agent with
true, correct and complete copies thereof.

     §6.26 Solvency. As of the Closing Date and after giving effect to the transactions contemplated by this
Agreement and the other Loan Documents, including all Loans made or to be made hereunder, and,
including, without limitation the provisions of §37 hereof, no Borrower is insolvent on a balance
sheet basis such that the sum of such Person’s assets exceeds the sum of such Person’s liabilities,
each Borrower is able to pay its debts as they become due, and each Borrower has sufficient capital
to carry on its business.

     §6.27 No Bankruptcy Filing. No Borrower is contemplating either the filing of a petition by it under any state or
federal bankruptcy or insolvency laws or the liquidation of its assets or property, and the
Borrowers have no knowledge of any Person contemplating the filing of any such petition against it.

     §6.28 No Fraudulent Intent. Neither the execution and delivery of this Agreement or any of the other Loan Documents nor
the performance of any actions required hereunder or thereunder is being undertaken by any Borrower
with or as a result of any actual intent by any of such Persons to hinder, delay or defraud any
entity to which any of such Persons is now or will hereafter become indebted.

     §6.29 Transaction in Best Interests of Borrowers; Consideration. The transaction evidenced by this Agreement and the other Loan Documents is in the best
interests of each Borrower. The direct and indirect benefits to inure to the Borrowers pursuant to
this Agreement and the other Loan Documents constitute substantially more than “reasonably
equivalent value” (as such term is used in §548 of the Bankruptcy Code) and “valuable
consideration,” “fair value,” and “fair consideration,” (as such terms are used in any applicable
state fraudulent conveyance law), in exchange for the benefits to be provided by the Borrowers
pursuant to this Agreement and the other Loan Documents, and but for the willingness of each
Subsidiary Borrower to be a co-borrower of the Loan, the Borrowers would be unable to obtain the
financing contemplated hereunder which financing will enable the Borrowers to have available
financing to conduct and expand their business.

61

 

     §6.30 OFAC. None of the Borrowers is (or will be) a person with whom any Lender is restricted from
doing business under OFAC (including, those Persons named on OFAC’s Specially Designated and
Blocked Persons list) or under any statute, executive order (including the September 24, 2001
Executive Order Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to
Commit, or Support Terrorism), or other governmental action and is not and shall not engage in any
dealings or transactions or otherwise be associated with such
persons. In addition, Borrowers hereby agree to provide to the Lenders any additional
information that a Lender deems necessary from time to time in order to ensure compliance with all
applicable laws concerning money laundering and similar activities.

     §7. AFFIRMATIVE COVENANTS.

     The Borrowers covenant and agree that, so long as any Loan, Note or Letter of Credit is
outstanding or any Lender has any obligation to make any Loans or issue Letters of Credit:

     §7.1 Punctual Payment. The Borrowers will duly and punctually pay or cause to be paid the principal and interest
on the Loans and all interest and fees provided for in this Agreement, all in accordance with the
terms of this Agreement and the Notes, as well as all other sums owing pursuant to the Loan
Documents in accordance with the terms hereof.

     §7.2 Maintenance of Office. The Borrowers will maintain their respective chief executive office at 1050 17th Street,
Suite 800, Denver, Colorado 80265, or at such other place in the United States of America as the
Borrowers shall designate upon prompt written notice to the Agent and the Lenders, where notices,
presentations and demands to or upon the Borrowers in respect of the Loan Documents may be given or
made.

     §7.3 Records and Accounts. The Borrowers will keep, and cause each of their respective Subsidiaries to keep true and
accurate records and books of account in which full, true and correct entries will be made in
accordance with GAAP (in each case, in all material respects). Neither any Borrower nor any of
their respective Subsidiaries shall, without the prior written consent of the Agent, not to be
unreasonably withheld, (x) make any material change to the accounting policies/principles used by
such Person in preparing the financial statements and other information described in §6.4 or §7.4,
or (y) change its fiscal year. Agent and the Lenders acknowledge that REIT’s fiscal year is a
calendar year.

     §7.4 Financial Statements, Certificates and Information. Borrowers will deliver or cause to be delivered to the Agent with sufficient copies for
each of the Lenders:

          (a) within five (5) days of the filing of REIT’s Form 10-K with the SEC, if applicable, but in
any event not later than one hundred twenty (120) days after the end of each calendar year, the
audited Consolidated balance sheet of the REIT and its Subsidiaries at the end of such year, and
the related audited consolidated statements of income, changes in capital and cash flows for such
year, setting forth in comparative form the figures for the previous fiscal year and all such
statements to be in reasonable detail, prepared in accordance with GAAP, together with a
certification by an Authorized Officer or the chief financial officer or accounting officer of the
REIT that the information contained in such financial statements fairly presents in all
material respects the financial position of the REIT and its Subsidiaries, and accompanied by
an

62

 

auditor’s report prepared without qualification as to the scope of the audit by a member firm

of the Mortgaged Properties, the Borrowers shall promptly and diligently comply with the
recommendations of the Environmental Engineer concerning the maintenance, operation or upkeep of

renewal or replacement prior to the expiration date of the current policies.

          (b) All policies of insurance required by this Agreement shall contain clauses or endorsements
to the effect that (i) no act or omission of the Borrowers or anyone acting for the Borrowers

deduction in respect of any liability of the Borrowers and the Agent, (iii) such insurance is
primary and without right of contribution from any other insurance which may be available, (iv)

or registered mail, and (v) that the Agent or the Lenders shall not be liable for any premiums
thereon or subject to any assessments thereunder, and shall in all events be in amounts sufficient
to avoid any coinsurance liability.

          (c) The insurance required by this Agreement may be effected through a blanket policy or
policies covering additional locations and property of the Borrowers and other Persons not included
in the Mortgaged Property, provided that such blanket policy or policies comply with all of
the terms and provisions of this §7.7 and contain endorsements or clauses assuring that any claim
recovery will not be less than that which a separate policy would provide, including a loss payable
endorsement favoring the Agent. The policy will be endorsed with a per location aggregate that
applies to the commercial general liability insurance.

          (d) All policies of insurance required by this Agreement shall be issued by companies licensed
to do business in the State where the policy is issued and also in the States where the Mortgaged
Property is located and having a rating in Best’s Key Rating Guide of at least “A” and a financial
size category of at least “X.”

          (e) No Borrower shall carry separate insurance, concurrent in kind or form or contributing in
the event of loss, with any insurance required under this Agreement unless such insurance complies
with the terms and provisions of this §7.7.

          (f) In the event of any loss or damage to the Mortgaged Property in excess of $1,000,000, the
Borrowers shall give prompt written notice to the insurance carrier and the Agent. Subject to the
provisions of (g) below, each Borrower hereby irrevocably authorizes and empowers the Agent, at the
Agent’s option and in the Agent’s sole discretion or at the request of the Required Lenders in
their sole discretion, as its attorney in fact, to make proof of such loss, to adjust and
compromise any claim under insurance policies, to appear in and prosecute any action arising from
such insurance policies, to collect and receive Insurance Proceeds and Condemnation Proceeds, and
to deduct therefrom the Agent’s reasonable expenses incurred in the collection of such Insurance
Proceeds; provided, however, that so long as no Event of Default has occurred and
is continuing and so long as the applicable Borrower shall in good faith

69

 

diligently pursue such claim, the applicable Borrower may make proof of loss and appear in any
proceedings or negotiations with respect to the adjustment of such claim, except that the
applicable Borrower may not settle, adjust or compromise any such claim without the prior written
consent of the Agent, which consent shall not be unreasonably withheld or delayed;
provided, further, that the applicable Borrower may make proof of loss and adjust
and compromise any claim under casualty insurance policies which is in an amount less than
$1,000,000 so long as no Event of Default has occurred and is continuing and so long as the
applicable Borrower shall in good faith diligently pursue such claim. Subject to the provisions of
(g) below, the Borrowers further authorize the Agent, at the Agent’s option, to (i) apply the
balance of such Insurance Proceeds and Condemnation Proceeds to the payment of the Obligations
whether or not then due, or (ii) if the Agent shall require the reconstruction or repair of the
Mortgaged Property, to hold the balance of such proceeds as trustee to be used to pay taxes,
charges, sewer use fees, water rates and assessments which may be imposed on the Mortgaged Property
which are then due and payable and the Obligations as they become due during the course of
reconstruction or repair of the Mortgaged Property and to pay, in accordance with such terms and
conditions as the Agent or other lenders of construction projects may prescribe, for the costs of
reconstruction or repair of the Mortgaged Property, and upon completion of such reconstruction or
repair to pay the excess to Borrower.

          (g) Notwithstanding the foregoing or anything to the contrary contained in the Mortgages, the
Agent shall make net Insurance Proceeds and Condemnation Proceeds available to the Borrowers to
reconstruct and repair the Mortgaged Property, in accordance with such terms and conditions as the
Agent may prescribe in the Agent’s discretion for the disbursement of the proceeds,
provided that (i) the cost of such reconstruction or repair is not estimated by the Agent
to exceed fifty percent (50%) of the replacement cost of the damaged Building (as reasonably
estimated by the Agent), (ii) no Default or Event of Default shall have occurred and be continuing,
(iii) the Borrowers shall have provided to the Agent additional security reasonably satisfactory to
Agent in an amount equal to the amount reasonably estimated by the Agent to be the amount in excess
of such proceeds which will be required to complete such repair or restoration, (iv) for
restorations in excess of $2,000,000, the Agent shall have approved the plans and specifications,
construction budget, construction contracts, and construction schedule for such repair or
restoration (provided that the Agent shall not disapprove such plans and specifications if
the Building is to be restored to substantially its condition immediately prior to such damage),
(v) the Borrowers shall have delivered to the Agent written agreements binding upon not less than
seventy-five percent (75%) of the tenants or other parties having present or future rights to
possession of any portion of the affected Mortgaged Property or having any right to require repair,
restoration or completion of the Mortgaged Property or any portion thereof (determined by reference
to those tenants in the aggregate occupying or having rights to occupy not less than seventy-five
percent (75%) of the Net Rentable Area of the Building so damaged), agreeing upon a date for
delivery of possession of the Mortgaged Property or their respective portions thereof, to permit
time which is sufficient in the judgment of the Agent for such repair or restoration and approving
the plans and specifications for such repair or restoration, or other evidence satisfactory to the
Agent that none of such tenants or other parties may terminate their Leases as a result of such
casualty or as a result of having a right to approve the plans and specifications for such repair
or restoration, (vi) the Agent shall reasonably determine that such repair or reconstruction can be
completed prior to the Revolving Credit Maturity Date, (vii) the Agent shall receive evidence
reasonably satisfactory to it that any such restoration, repair or

70

 

rebuilding complies in all respects with any and all applicable state, federal and local laws,
ordinances and regulations, including without limitation, zoning laws, ordinances and regulations,
and that all required permits, licenses and approvals relative thereto have been or will be issued
in a manner so as not to materially impede the progress of restoration, (viii) the Agent shall
receive evidence reasonably satisfactory to it that the insurer under such policies of fire or
other casualty insurance does not assert any defense to payment under such policies against any
Borrower or the Agent, and (ix) with respect to any Taking, Agent shall determine that following
such repair or restoration there shall be no more than the lesser of (i) a twenty-five percent
(25%) reduction in occupancy or rental income from the Mortgaged Property so affected by such
specific condemnation or taking (excluding any proceeds from rental loss insurance or proceeds from
such award allocable to rent) or (ii) a fifteen percent (15%) reduction in occupancy or in rental
income from all of the Mortgaged Properties (excluding any proceeds from rental loss insurance or
proceeds of such award allocable to rent), after giving effect to the current condemnation or
taking and any previous condemnations or takings which may have occurred. Any excess Insurance
Proceeds shall be paid to the Borrowers, or if an Event of Default has occurred and is continuing,
such proceeds shall be applied to the payment of the Obligations, unless in either case by the
terms of the applicable insurance policy the excess proceeds are required to be returned to such
insurer. Any excess Condemnation Proceeds shall be applied to the payment of the Obligations. In
no event shall the provisions of this section be construed to extend the Revolving Credit Maturity
Date or to limit in any way any right or remedy of the Agent upon the occurrence of an Event of
Default hereunder. If the Mortgaged Property is sold then the new owners shall be required to
secure and maintain their own insurance as listed above or if the Mortgaged Property is acquired by
the Agent, then the Agent shall be required to procure its own insurance as listed above. There
shall be no assignment of the policy to either the new owners or Agent.

     §7.8 Taxes. The Borrowers will, and will cause their respective Subsidiaries to, duly pay and
discharge, or cause to be paid and discharged, all taxes, assessments and other governmental
charges imposed upon them or upon the Mortgaged Properties or the other Real Estate, sales and
activities, or any part thereof, or upon the income or profits therefrom that if unpaid might by
law become a lien or charge upon any of its property or other Liens affecting any of the Collateral
or other property of Borrowers, or, with respect to their respective Subsidiaries that could
reasonably be expected to have a Material Adverse Effect, provided that any such tax,
assessment, charge or levy or claim need not be paid if the validity or amount thereof shall
currently be contested in good faith by appropriate proceedings which shall suspend the collection
thereof with respect to such property, neither such property nor any portion thereof or interest
therein would be in any danger of sale, forfeiture or loss by reason of such proceeding and such
Borrower or any such Subsidiary shall have set aside on its books adequate reserves in accordance
with GAAP; and provided, further, that forthwith upon the commencement of
proceedings to foreclose any lien that may have attached as security therefor, such Borrower or any
such Subsidiary either (i) will provide a bond issued by a surety reasonably acceptable to the
Agent and sufficient to stay all such proceedings or (ii) if no such bond is provided, will pay
each such tax, assessment, charge or levy.

     §7.9 Inspection of Properties and Books. The Borrowers will, and will cause their respective
Subsidiaries to, permit the Agent and the Lenders, at the Borrowers’ expense and upon reasonable
prior notice, to visit and inspect any of the properties of the Borrowers or any of

71

 

their respective Subsidiaries (subject to the rights of tenants under their Leases, and Agent
and Lender agree to use commercially reasonable efforts not to interfere with such rights) during
normal business hours, to examine the books of account of the Borrowers and their respective
Subsidiaries (and to make copies thereof and extracts therefrom) and to discuss the affairs,
finances and accounts of the Borrowers and their respective Subsidiaries with, and to be advised as
to the same by, their respective officers, partners or members, all at such reasonable times and
intervals as the Agent or any Lender may reasonably request, provided that so long as no
Default or Event of Default shall have occurred and be continuing, the Borrowers shall not be
required to pay for such visits and inspections more often than once in any twelve (12) month
period. The Lenders shall use good faith efforts to coordinate such visits and inspections so as
to minimize the interference with and disruption to the normal business operations of the Borrowers
and their respective Subsidiaries.

     §7.10 Compliance with Laws, Contracts, Licenses, and Permits. The Borrowers will, and will
cause each of their respective Subsidiaries to, comply in all respects with (i) all applicable laws
and regulations now or hereafter in effect wherever its business is conducted, including all
Environmental Laws, (ii) the provisions of its corporate charter, partnership agreement, limited
liability company agreement or declaration of trust, as the case may be, and other charter
documents and bylaws, (iii) all agreements and instruments to which it is a party or by which it or
any of its properties may be bound, (iv) all applicable decrees, orders, and judgments, and (v) all
licenses and permits required by applicable laws and regulations for the conduct of its business or
the ownership, use or operation of its properties, except where a failure to so comply with any of
clauses (i) through (v) could not reasonably be expected to have a Material Adverse Effect. If any
authorization, consent, approval, permit or license from any officer, agency or instrumentality of
any government shall become necessary or required in order that the Borrowers or their respective
Subsidiaries may fulfill any of its obligations hereunder, the Borrowers or such Subsidiary will
immediately take or cause to be taken all reasonable steps necessary to obtain such authorization,
consent, approval, permit or license and furnish the Agent and the Lenders with evidence thereof.
Borrowers shall develop and implement such programs, policies and procedures as are necessary to
comply with the Patriot Act and shall promptly advise Agent in writing in the event that Borrowers
shall determine that any investors in Borrowers are in violation of such act.

     §7.11 Further Assurances. The Borrowers will and will cause each of their respective
Subsidiaries to, cooperate with the Agent and the Lenders and execute such further instruments and
documents as the Lenders or the Agent shall reasonably request to carry out to their satisfaction
the transactions contemplated by this Agreement and the other Loan Documents.

     §7.12 Management. The Borrowers shall not enter into any Management Agreement with a third
party manager for the Mortgaged Property without the prior written consent of the Agent (which
shall not be unreasonably withheld), and after such approval, no such Management Agreement shall be
modified in any material respect or terminated without Agent’s prior written approval, such
approval not to be unreasonably withheld. Agent may condition any approval of a new manager upon
the execution and delivery to Agent of collateral assignment of such Management Agreement to Agent
and a subordination of the manager’s rights thereunder to the rights of the Agent and the Lenders
under the Loan Documents. The Management Agreements

72

 

described on Schedule 6.23 hereto relating to the initial Mortgaged Properties are
approved by Agent.

     §7.13 Leases of the Property. The Borrowers will give notice to the Agent of any proposed new

copy of the proposed Lease and any and all agreements or documents related thereto, current
financial information for the proposed tenant and any guarantor of the proposed Lease and such
other information as the Agent may reasonably request. No Borrower will lease all or any portion
of a Mortgaged Property or amend, supplement or otherwise modify, terminate or cancel, or accept
the surrender of, or consent to the assignment or subletting of, or grant any concessions to or
waive the performance of any obligations of any tenant, lessee or licensee under, any now existing
or future Lease at any Mortgaged Property without the prior written consent of the Agent not to be
unreasonably withheld, conditioned or delayed; provided, however, that without the
prior written approval of Agent, the Borrower may enter into a new Lease for a Mortgaged Property
involving less than 1.0 mega watts of critical power and the Borrower may amend, supplement or
otherwise modify, terminate or cancel, or accept the surrender of, or consent to the assignment or
subletting of, or grant any concessions to or waive the performance of any obligations of any
tenant, lessee or licensee under any now existing or future Lease at a Mortgaged Property involving
less than 500 kilo watts of critical power, provided that such Lease is consistent with sound
leasing and management practices for similar properties, and provided, further,
that without the prior written approval of Agent, Borrower may (i) enter into expansions of any
Lease by up to an additional 500 kilo watts of critical power, (ii) expand or contract power,
“so-called” cross connects, “so-called” remote hands, “so-called” interconnection services, and
other similar services offered in the ordinary course of business with respect to any now existing
or future Lease, and/or (iii) provide abatements or credits to any tenant, lessee or licensee in
the ordinary course of business under any now existing or future Lease. In addition, any
concessions or waivers of performance already contained in Leases in place as of the Closing Date
are hereby approved by Agent. If a Borrower submits to Agent a written request for approval with
respect to a proposed Lease and/or any such action with respect to a Lease and Agent fails to
approve or disapprove any such proposed Lease and/or any such action within seven (7) days after
Agent receives from such Borrower such request together with a copy of the final version of such
proposed Lease, as applicable, then Borrower may provide to the Agent a second written request for
approval with respect to a proposed Lease which includes the following in all capital, bolded,
block letters on the first page thereof:

“THE FOLLOWING REQUEST REQUIRES A RESPONSE WITHIN FIVE (5) DAYS OF
RECEIPT. FAILURE TO DO SO WILL BE DEEMED AN APPROVAL OF THE
REQUEST.”

and if the foregoing legend is included by the Borrower in its communication, the Agent shall be
deemed to have approved or consented to such proposed Lease and/or such action if the Agent fails
to object to such proposed Lease and/or such action within five (5) days (without counting the day
of receipt) of Agent’s receipt of such second notice.

     Agent agrees, upon request, to enter into a non-disturbance agreement in form and substance
reasonably acceptable to the Agent and any such tenant and/or licensee.

Subsidiary to, directly or indirectly, engage in any line of business other than the ownership,
operation and development of Data Center Properties or businesses incidental thereto.

     §7.15 Registered Servicemark. Without prior written notice to the Agent, none of the
Mortgaged Properties shall be owned or operated by the Borrowers under any registered or protected

(other than the “CoreSite(s)” name and the “CoreSite(s)” logo).

     §7.16 Ownership of Real Estate. Without the prior written consent of Agent, all Real Estate
and all interests (whether direct or indirect) of Parent Borrower or REIT in any real estate assets

Subsidiaries of additional Real Estate, either by acquiring title to such Real Estate directly in
the name of Parent Borrower or any such Subsidiary or by acquiring direct or indirect ownership
interests in a partnership, corporation or limited liability company that owns directly such Real
Estate (subject in all respects to compliance by Parent Borrower and its Subsidiaries with the
terms of this Agreement), the sales price of which is paid in whole or in part by the issuance of

79

 

     The Borrowers shall:

               (i) in the event of any change in applicable Environmental Laws governing the assessment,
release or removal of Hazardous Substances, take all reasonable action as required by such Laws

Borrowers) to confirm that no Hazardous Substances are or ever were Released or disposed of on the
Mortgaged Properties in violation of applicable Environmental Laws; and

               (ii) if any Release or disposal of Hazardous Substances which Borrowers may be legally
obligated to contain, correct or otherwise remediate or which may otherwise expose such Borrowers
to liability shall occur or shall have occurred on any Mortgaged Property (including without
limitation any such Release or disposal occurring prior to the acquisition or leasing of such
Mortgaged Property by the Borrowers), the relevant Borrower shall, after obtaining knowledge

financial resources is taking reasonable action to remediate or manage such event to the reasonable
satisfaction of the Agent or has taken and is diligently pursuing a challenge to any such alleged
legal obligation through appropriate administrative or judicial proceedings. The Agent may, at its
own cost and expense, engage its own Environmental Engineer to review the environmental assessments
and the compliance with the covenants contained herein.

     At any time after an Event of Default shall have occurred hereunder and is continuing, the
Agent may at its election (and will at the request of the Required Lenders) obtain such
environmental assessments of any or all of the Mortgaged Properties prepared by an Environmental
Engineer as may be necessary or advisable for the purpose of evaluating or confirming (i) whether
any Hazardous Substances are present in the soil or water at or adjacent to any such Mortgaged
Property in a quantity or condition that is required to be contained, corrected or otherwise
remediated by the owner or operator of the Mortgaged Property pursuant to applicable Environmental
Laws and (ii) whether the use and operation of any such Mortgaged Property complies with all
Environmental Laws to the extent required by the Loan Documents. Additionally, at any time that
the Agent or the Required Lenders shall have reasonable and objective grounds to believe that a
Release or threatened Release of Hazardous Substances may have occurred at or from any Mortgaged
Property which the owner or operator of such property would be obligated to contain, correct or
otherwise remediate pursuant to applicable Environmental Laws or which otherwise may expose such
Person to liability under Environmental Laws, or that any of the Mortgaged Property is not in
compliance with Environmental Laws to the extent required by the Loan Documents, Borrowers shall
promptly upon the request of Agent obtain and deliver to Agent such environmental assessments of
such Mortgaged Property prepared by an Environmental Engineer as may be reasonably necessary or
advisable for the purpose of evaluating or confirming (i) whether any Hazardous Substances are
present in the soil or water at or adjacent to such Mortgaged Property and (ii) whether the use and
operation of such Mortgaged Property complies with all Environmental Laws to the extent required by
the Loan Documents. Environmental assessments may include detailed visual

80

 

inspections of such Mortgaged Property including, without limitation, any and all storage
areas, storage tanks, drains, dry wells and leaching areas, and the taking of soil samples, as well
as such other investigations or analyses as are reasonably necessary or appropriate for a complete
determination of the compliance of such Mortgaged Property and the use and operation thereof with
all applicable Environmental Laws. All environmental assessments contemplated by this §8.6 shall
be at the sole cost and expense of the Borrowers.

     §8.7 Distributions.

          (a) Parent Borrower shall not pay any Distribution to the partners, members or other owners of
Parent Borrower, and REIT shall not pay any Distribution to its shareholders, if such Distribution
is in excess of the amount which (i) when added to the amount of all other Distributions paid in
the same calendar quarter and (A) the preceding calendar quarters from the date of this Agreement
or (B) the preceding three (3) calendar quarters (whichever is less), would exceed ninety-five
percent (95%) of such Person’s Funds from Operations for such period; provided that (x) the
limitations contained in this §8.7(a) shall not preclude the Parent Borrower from making
Distributions each year to its owners, pro rata in accordance with percentage interests, such that
the amount received by REIT is sufficient to cover (i) the liability of REIT for Taxes plus (ii) an
amount equal to the greater of: (1) the amount estimated by REIT in good faith after reasonable
diligence to be necessary to permit REIT to distribute to its shareholders with respect to any
calendar year (whether made during such year or after the end thereof) 100% of the “real estate
investment trust taxable income” of REIT within the meaning of Section 857(b)(2) of the Code,
determined without regard to deductions for dividends paid and the exclusions set forth in Sections
857(b)(2)(C), (D), (E) and (F) of the Code but including therein all net capital gains and net
recognized built-in gains within the meaning of Treasury Regulations Section 1.337(d)-6 (whether or
not such gains might otherwise be excluded or excludable therefrom); or (2) the amount that is
estimated by REIT in good faith after reasonable diligence to be necessary either to maintain the
REIT Status of REIT (if REIT exists) or to enable REIT to avoid the incurrence of any tax for any
calendar year that could be avoided by reason of a distribution by REIT to its shareholders, with
such distributions to be made as and when determined by REIT, whether during or after the end of
the relevant calendar year; and (y) REIT shall be allowed to pay Distributions of the amount
received pursuant to this §8.7(a) to its shareholders.

          (b) In the event that an Event of Default shall have occurred and be continuing, (i) Parent
Borrower shall make no Distributions, and REIT shall not pay any Distribution to its shareholders,
other than, if REIT exists and has elected REIT Status, Distributions pro rata in accordance with
percentage interests to the owners of Parent Borrower such that REIT receives an amount that is
estimated by REIT in good faith after reasonable diligence to be necessary either to maintain the
REIT Status of REIT under the Code for any calendar year, or to enable REIT to avoid the payment of
any tax for any calendar year that could be avoided by reason of a distribution by REIT to its
shareholders, with such distributions to be made as and when determined by REIT, whether during or
after the end of the relevant tax year and REIT shall be allowed to make Distributions of such
amounts to its shareholders.

          (c) Notwithstanding the foregoing, at any time when an Event of Default under §12.1(a), (b),
(h), (i) or (j) shall have occurred or the maturity of the Obligations has been

81

 

accelerated, Parent Borrower shall not, and shall not permit REIT to, make any Distributions
whatsoever, directly or indirectly.

     §8.8 Asset Sales. Except for the transactions described on Schedule 7.24 or

material asset other than pursuant to a bona fide arm’s length transaction. No Borrower shall
sell, transfer or otherwise dispose of any Real Estate in one transaction or a series of
transactions during any four (4) consecutive fiscal quarters in excess of an amount equal to
thirty-five percent (35%) of Gross Asset Value, except as the result of a condemnation or casualty
and except for the granting of Permitted Liens, as applicable, without the prior written consent of
Agent and the Required Lenders.

     §8.9 [Intentionally Omitted.]

     §8.10 Restriction on Prepayment of Indebtedness. Borrower will not (a) prepay, redeem,
defease, purchase or otherwise retire the principal amount, in whole or in part, of any
Indebtedness other than the Obligations after the occurrence of any Event of Default;
provided, that the foregoing shall not prohibit (x) the prepayment of Indebtedness which is
financed solely from the proceeds of a new loan which would otherwise be permitted by the terms of
§8.1; and (y) the prepayment, redemption, defeasance or other retirement of the principal of
Indebtedness secured by Real Estate which is satisfied solely from the proceeds of a sale of the
Real Estate securing such Indebtedness; and (b) modify any document evidencing any Indebtedness

could result in such use becoming a non-conforming use under any zoning ordinance or any other
applicable land use law, rule or regulation. No Borrower shall initiate any change in any laws,
requirements of governmental authorities or obligations created by private contracts and Leases
which now or hereafter may materially adversely affect the ownership, occupancy, use or operation
of any Mortgaged Property.

Schedule 6.15 attached hereto and Schedule 7.24 hereto and (iii) transactions
pursuant to the reasonable requirements of the business of such Person and upon fair and reasonable

85

on behalf of the Borrowers or any of their respective Subsidiaries contained in this Agreement, the
other Loan Documents or in any document or instrument delivered pursuant to or in connection with
this Agreement shall be true in all material respects both as of the date as of which they were
made and shall also be true in all material respects as of the time of the making of such Loan or
the issuance of such Letter of Credit, with the same effect as if made at and as of that time,
except to the extent of changes resulting from transactions permitted by the Loan Documents (it

          (e) any of the Borrowers shall fail to perform any other term, covenant or agreement contained
herein or in any of the other Loan Documents which they are required to perform (other than those

the other Loan Documents), and such failure shall continue for thirty (30) days after Borrower
receives from Agent written notice thereof, and in the case of a default that cannot be cured
within such thirty (30)-day period despite Borrower’s diligent efforts but is susceptible of being
cured within ninety (90) days of Borrower’s receipt of Agent’s original notice, then Borrower shall
have such additional time as is reasonably necessary to effect such cure, but in no event in excess
of ninety (90) days from Borrower’s receipt of Lender’s original notice;

constituted;

          (k) there shall remain in force, undischarged, unsatisfied and unstayed, for more than sixty
(60) days one or more uninsured or unbonded final judgments against Parent Borrower or any
Subsidiary Borrower that, either individually or in the aggregate, exceed $25,000,000;

          (l) any of the Loan Documents shall be canceled, terminated, revoked or rescinded otherwise
than in accordance with the terms thereof or the express prior written agreement, consent or
approval of the Required Lenders, or any action at law, suit in equity or other legal proceeding to
cancel, revoke or rescind any of the Loan Documents shall be commenced by or on behalf of any of
the Borrowers, or any court or any other governmental or regulatory authority or agency of
competent jurisdiction shall make a determination, or issue a judgment, order, decree or ruling, to

accordance with the terms thereof;

88

 

          (m) any dissolution, termination, partial or complete liquidation, merger or consolidation of

the Borrowers shall occur other than as permitted under the terms of this Agreement or the other
Loan Documents;

          (n) with respect to any Guaranteed Pension Plan, an ERISA Reportable Event shall have occurred
and such event reasonably would be expected to result in liability of any of the Borrowers to pay
money to the PBGC or such Guaranteed Pension Plan in an aggregate amount exceeding $25,000,000 and
one of the following shall apply with respect to such event: (x) such event in the circumstances
occurring reasonably would be expected to result in the termination of such Guaranteed Pension Plan

          (o) any Change of Control shall occur;

          (p) an Event of Default under any of the other Loan Documents shall occur;

then, and upon any such Event of Default, the Agent may, and upon the request of the Required

Agreement, the Notes, the Letters of Credit and the other Loan Documents 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 Borrowers;
provided that in the event of any Event of Default specified in §12.1(h), §12.1(i) or
§12.1(j), all such amounts shall become immediately due and payable automatically and without any
requirement of presentment, demand, protest or other notice of any kind from any of the Lenders or
the Agent. Upon demand by Agent or the Majority Lenders in their absolute and sole discretion
after the occurrence and during the continuance of an Event of Default, and regardless of whether
the conditions precedent in this Agreement for a Revolving Credit Loan have been satisfied, the
Revolving Credit Lenders will cause a Revolving Credit Loan to be made in the undrawn amount of all
Letters of Credit. The proceeds of any such Revolving Credit Loan will be pledged to and held by
Agent as security for any amounts that become payable under the Letters of Credit and all other
Obligations. In the alternative, if demanded by Agent in its absolute and sole discretion after
the occurrence and during the continuance of an Event of Default, Borrowers will deposit with and
pledge to Agent cash in an amount equal to the amount of all undrawn Letters of Credit. Such
amounts will be pledged to and held by Agent for the benefit of the Lenders as security for any
amounts that become payable under the Letters of Credit and all other Obligations. Upon any draws
under Letters of Credit, at Agent’s sole discretion, Agent may apply any such amounts to the
repayment of amounts drawn thereunder and upon the expiration of the Letters of Credit any
remaining amounts will be applied to the payment of all other Obligations or if there are no
outstanding Obligations and Lenders have no further obligation to make Revolving Credit Loans or
issue Letters of Credit or if such excess no longer exists, such proceeds deposited by Borrowers
will be released to Borrowers.

     §12.2 Certain Cure Periods; Limitation of Cure Periods.

89

 

          (a) Notwithstanding anything contained in §12.1 to the contrary, (i) no Event of Default shall
exist hereunder upon the occurrence of any failure described in §12.1(b) in the event that the
Borrowers cure such Default within five (5) Business Days after the date such payment is due,
provided that no such cure period shall apply to any payments due upon the maturity of the
Notes, and (ii) no Event of Default shall exist hereunder upon the occurrence of any failure
described in §12.1(e) in the event that, if such Default consists of the failure to provide
insurance as required by §7.7, the Borrowers cure such Default within fifteen (15) days following
receipt of written notice of such Default or with respect to the occurrence of any other failure
described in §12.1(e) in the event such failure shall continue for thirty (30) days after Borrower
receives from Agent written notice thereof, and in the case of a default that cannot be cured
within such thirty (30) day period despite Borrower’s diligent efforts but is susceptible of being
cured within ninety (90) days of Borrower’s receipt of Agent’s original notice, then Borrower shall
have such additional time as is reasonably necessary to effect such cure, but in no event in excess
of ninety (90) days from Borrower’s receipt of Agent’s original notice, provided that the
provisions of this clause (ii) shall not pertain to any default consisting of a failure to comply
with §8.1, §8.2, §8.3, §8.4, §8.7, §8.8, or §8.14, or to any Default excluded from any provision of
cure of defaults contained in any other of the Loan Documents.

          (b) In the event that there shall occur any Default that affects only certain Mortgaged
Property or the owner(s) thereof (if such owner is a Subsidiary Borrower), then the Borrowers may
elect to cure such Default (so long as no other Default or Event of Default would arise as a
result) by electing to have Agent remove such Mortgaged Property from the calculation of Borrowing
Base Availability and by reducing the outstanding Loans by the amount of the Borrowing Base
Availability attributable to such Mortgaged Property, in which event such removal and reduction
shall be completed within thirty (30) days after receipt of notice of such Default from the Agent
or the Required Lenders.

     §12.3 Termination of Commitments. If any one or more Events of Default specified in §12.1(h),
§12.1(i) or §12.1(j) shall occur, then immediately and without any action on the part of the Agent
or any Lender any unused portion of the credit hereunder shall terminate and the Lenders shall be
relieved of all obligations to make Loans or issue Letters of Credit to the Borrowers. If any
other Event of Default shall have occurred, the Agent may, and upon the election of the Majority
Lenders shall, by notice to the Borrowers terminate the obligation to make Revolving Credit Loans
and issue Letters of Credit to the Borrowers. No termination under this §12.3 shall relieve the
Borrowers of their obligations to the Lenders arising under this Agreement or the other Loan
Documents.

     §12.4 Remedies. To the extent permitted by applicable law, in case any one or more Events of
Default shall have occurred and be continuing, and whether or not the Lenders shall have
accelerated the maturity of the Loans pursuant to §12.1, the Agent on behalf of the Lenders may,
and upon the consent of the Required Lenders shall, proceed to protect and enforce their rights and
remedies under this Agreement, the Notes and/or any of the other Loan Documents by suit in equity,
action at law or other appropriate proceeding, including to the full extent permitted by applicable
law the specific performance of any covenant or agreement contained in this Agreement and the other
Loan Documents, the obtaining of the ex parte appointment of a receiver, and, if any amount shall
have become due, by declaration or otherwise, the enforcement of the payment thereof. No remedy
herein conferred upon the Agent or the holder of any Note is

90

 

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 now or hereafter existing at law or
in equity or by statute or any other provision of law. Notwithstanding the provisions of this
Agreement providing that the Loans may be evidenced by multiple Notes in favor of the Lenders, the
Lenders acknowledge and agree that only the Agent may exercise any remedies arising by reason of a
Default or Event of Default. If any Borrower fails to perform any agreement or covenant contained
in this Agreement or any of the other Loan Documents beyond any applicable period for notice and
cure, Agent may itself perform, or cause to be performed, any agreement or covenant of such Person
contained in this Agreement or any of the other Loan Documents which such Person shall fail to
perform, and the out-of-pocket costs of such performance, together with any reasonable expenses,
including reasonable attorneys’ fees actually incurred (including attorneys’ fees incurred in any
appeal) by Agent in connection therewith, shall be payable by Borrowers upon demand and shall
constitute a part of the Obligations and shall if not paid within thirty (30) days after demand
bear interest at the rate for overdue amounts as set forth in this Agreement. In the event that
all or any portion of the Obligations is collected by or through an attorney-at-law, the Borrowers
shall pay all costs of collection including, but not limited to, reasonable attorney’s fees.

     §12.5 Distribution of Collateral Proceeds. In the event that, following the occurrence and
during the continuance of any Event of Default, any monies are received in connection with the
enforcement of any of the Loan Documents, or otherwise with respect to the realization upon any of
the Collateral or other assets of Borrowers, such monies shall be distributed for application as
follows:

          (a) First, to the payment of, or (as the case may be) the reimbursement of the Agent for or in
respect of, all reasonable out-of-pocket costs, expenses, disbursements and losses which shall have
been paid, incurred or sustained by the Agent in accordance with the terms of the Loan Documents to
protect or preserve the Collateral or in connection with the collection of such monies by the
Agent, for the exercise, protection or enforcement by the Agent of all or any of the rights,
remedies, powers and privileges of the Agent or the Lenders under this Agreement or any of the
other Loan Documents or in respect of the Collateral or in support of any provision of adequate
indemnity to the Agent against any taxes or liens which by law shall have, or may have, priority
over the rights of the Agent or the Lenders to such monies;

          (b) Second, to all other Obligations (including any Letter of Credit Liabilities and any
interest, expenses or other obligations incurred after the commencement of a bankruptcy) in such
order or preference as the Required Lenders shall determine; provided, that (i) Swing Loans
shall be repaid first, (ii) distributions in respect of such other Obligations shall include, on a
pari passu basis, any Agent’s fee payable pursuant to §4.2; (iii) in the event that any Lender
shall have wrongfully failed or refused to make an advance under §2.5(d), §2.7 or §2.10(f) and such
failure or refusal shall be continuing, advances made by other Lenders during the pendency of such
failure or refusal shall be entitled to be repaid as to principal and accrued interest in priority
to the other Obligations described in this subsection (b); and

          (c) Third, the excess, if any, shall be returned to the Borrowers or to such other Persons as
are entitled thereto.

91

 

§13. SETOFF.

     Regardless of the adequacy of any Collateral, during the continuance of any Event of Default,
any deposits (general or specific, time or demand, provisional or final, regardless of currency,
maturity, or the branch where such deposits are held) or other sums credited by or due from any
Lender or any Affiliate thereof to the Borrowers and any securities or other property of the
Borrowers in the possession of such Lender or any Affiliate may, without notice to any Borrower
(any such notice being expressly waived by Borrowers) but with the prior written approval of Agent,
be applied to or set off against the payment of Obligations and any and all other liabilities,
direct, or indirect, absolute or contingent, due or to become due, now existing or hereafter
arising, of the Borrowers to such Lender. Each of the Lenders agrees with each other Lender that
if such Lender shall receive from a Borrower, whether by voluntary payment, exercise of the right
of setoff, or otherwise, and shall retain and apply to the payment of the Note or Notes held by
such Lender (but excluding the Swing Loan Note) any amount in excess of its ratable portion of the
payments received by all of the Lenders with respect to the Notes held by 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 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.

§14. THE AGENT.

     §14.1 Authorization. The 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 Agent, together with such powers as 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 Agent. The obligations of the Agent hereunder
are primarily administrative in nature, and nothing contained in this Agreement or any of the other
Loan Documents shall be construed to constitute the Agent as a trustee for any Lender or to create
an agency or fiduciary relationship. Agent shall act as the contractual representative of the
Lenders hereunder, and notwithstanding the use of the term “Agent”, it is understood and agreed
that Agent shall not have any fiduciary duties or responsibilities to any Lender by reason of this
Agreement or any other Loan Document and is acting as an independent contractor, the duties and
responsibilities of which are limited to those expressly set forth in this Agreement and the other
Loan Documents. The Borrowers and any other Person shall be entitled to conclusively rely on a
statement from the Agent that it has the authority to act for and bind the Lenders pursuant to this
Agreement and the other Loan Documents.

     §14.2 Employees and Agents. The 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 Agent may utilize the services of such Persons as the Agent may reasonably
determine, and all reasonable fees and expenses of any such Persons shall be paid by the Borrowers.

92

 

     §14.3 No Liability. Neither the 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 (a) 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 Agent or such other Person, as the case may be, shall be
liable for losses due to its willful misconduct or gross negligence as finally determined by a
court of competent jurisdiction after the expiration of all applicable appeal periods or (b) any
action taken or not taken by Agent with the consent or at the request of the Required Lenders. The
Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of
Default, except with respect to defaults in the payment of principal, interest and fees required to
be paid to the Agent for the account of the Lenders, unless the Agent has received notice from a
Lender or the Borrowers referring to the Loan Documents and describing with reasonable specificity
such Default or Event of Default and stating that such notice is a “notice of default”.

     §14.4 No Representations. The Agent shall not be responsible for the execution or validity or
enforceability of this Agreement, the Notes, any of the other Loan Documents or any instrument at
any time constituting, or intended to constitute, collateral security for the Notes, or for the
value of any such collateral security or for the validity, enforceability or collectability of any
such amounts owing with respect to the Notes, or for any recitals or statements, warranties or
representations made herein, or any agreement, instrument or certificate delivered in connection
therewith or in any of the other Loan Documents or in any certificate or instrument hereafter
furnished to it by or on behalf of the Borrowers 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 herein or in any of the other Loan Documents. The Agent shall not be bound
to ascertain whether any notice, consent, waiver or request delivered to it by the Borrowers or any
holder of any of the Notes shall have been duly authorized or is true, accurate and complete. The
Agent has not 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 Borrowers or any of their respective Subsidiaries, or the value of the Collateral
or any other assets of the Borrowers or any of their respective Subsidiaries. Each Lender
acknowledges that it has, independently and without reliance upon the Agent 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. Each Lender also acknowledges that it will,
independently and without reliance upon the Agent or any other Lender, based upon such information
and documents as it deems appropriate at the time, continue to make its own credit analysis and
decisions in taking or not taking action under this Agreement and the other Loan Documents.
Agent’s Special Counsel has only represented Agent and KeyBank in connection with the Loan
Documents and the only attorney client relationship or duty of care is between Agent’s Special
Counsel and Agent or KeyBank. Each Lender has been independently represented by separate counsel on
all matters regarding the Loan Documents and the granting and perfecting of liens in the
Collateral.

     §14.5 Payments.

93

 

          (a) A payment by the Borrowers to the Agent hereunder or under any of the other Loan Documents
for the account of any Lender shall constitute a payment to such Lender. The Agent agrees to
distribute to each Lender not later than one Business Day after the Agent’s receipt of good funds,
determined in accordance with the Agent’s customary practices, such Lender’s pro rata share of
payments received by the Agent for the account of the Lenders except as otherwise expressly
provided herein or in any of the other Loan Documents. In the event that the Agent fails to
distribute such amounts within one Business Day as provided above, the Agent shall pay interest on
such amount at a rate per annum equal to the Federal Funds Effective Rate from time to time in
effect.

          (b) If in the opinion of the 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
liability, it may refrain from making such distribution until its right to make such distribution
shall have been adjudicated by a court of competent jurisdiction. If a court of competent
jurisdiction shall adjudge that any amount received and distributed by the Agent is to be repaid,
each Person to whom any such distribution shall have been made shall either repay to the 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.

     §14.6 Holders of Notes. Subject to the terms of §18, the Agent may deem and treat the payee
of any Note 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.

     §14.7 Indemnity. The Lenders ratably agree hereby to indemnify and hold harmless the Agent
from and against any and all claims, actions and suits (whether groundless or otherwise), losses,
damages, costs, expenses (including any expenses for which the Agent has not been reimbursed by the
Borrowers as required by §15), and liabilities of every nature and character arising out of or
related to this Agreement, the Notes, or any of the other Loan Documents or the transactions
contemplated or evidenced hereby or thereby, or the Agent’s actions taken hereunder or thereunder,
except to the extent that any of the same shall be directly caused by the Agent’s willful
misconduct or gross negligence as finally determined by a court of competent jurisdiction after the
expiration of all applicable appeal periods. The agreements in this §14.7 shall survive the
payment of all amounts payable under the Loan Documents.

     §14.8 Agent as Lender. In its individual capacity, KeyBank 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 as it would have were it not also the Agent.

     §14.9 Resignation. The Agent may resign at any time by giving thirty (30) calendar days’
prior written notice thereof to the Lenders and the Borrowers. The Required Lenders may remove the
Agent from its capacity as Agent in the event of the Agent’s gross negligence or willful
misconduct. Any such resignation or removal may at Agent’s option also constitute Agent’s
resignation as Issuing Lender and Swing Loan Lender. Upon any such resignation, or removal, the
Required Lenders, subject to the terms of §18.1, shall have the right to appoint as a successor
Agent and, if applicable, Issuing Lender and Swing Loan Lender, any Lender or any

94

 

bank whose senior debt obligations are rated not less than “A” or its equivalent by Moody’s or
not less than “A” or its equivalent by S&P and which has a net worth of not less than $500,000,000;
provided that any such replacement Agent shall have a Commitment Percentage of not less than ten
percent (10%). Unless a Default or Event of Default shall have occurred and be continuing, such
successor Agent and, if applicable, Issuing Lender and Swing Loan Lender, shall be reasonably
acceptable to the Borrowers. If no successor Agent shall have been appointed and shall have
accepted such appointment within thirty (30) days after the retiring Agent’s giving of notice of
resignation or the Required Lender’s removal of the Agent, then the retiring or removed Agent may,
on behalf of the Lenders, appoint a successor Agent, which shall be any Lender or any financial
institution whose senior debt obligations are rated not less than “A2” or its equivalent by Moody’s
or not less than “A” or its equivalent by S&P and which has a net worth of not less than
$500,000,000. Upon the acceptance of any appointment as Agent and, if applicable, Issuing Lender
and Swing Loan Lender, hereunder by a successor Agent and, if applicable, Issuing Lender and Swing
Loan Lender, such successor Agent and, if applicable, Issuing Lender and Swing Loan Lender, shall
thereupon succeed to and become vested with all the rights, powers, privileges and duties of the
retiring or removed Agent and, if applicable, Issuing Lender and Swing Loan Lender, and the
retiring or removed Agent and, if applicable, Issuing Lender and Swing Loan Lender, shall be
discharged from its duties and obligations hereunder as Agent and, if applicable, Issuing Lender
and Swing Loan Lender. After any retiring Agent’s resignation or removal, the provisions of this
Agreement and the other Loan Documents shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Agent, Issuing Lender and Swing
Loan Lender. If the resigning or removed Agent shall also resign as the Issuing Lender, such
successor Agent shall issue letters of credit in substitution for the Letters of Credit, if any,
outstanding at the time of such succession or shall make other arrangements satisfactory to the
current Issuing Lender, in either case, to assume effectively the obligations of the current Agent
with respect to such Letters of Credit. Upon any change in the Agent under this Agreement, the
resigning or removed Agent shall execute such assignments of and amendments to the Loan Documents
as may be necessary to substitute the successor Agent for the resigning or removed Agent.

     §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 Agent may and, if (a) so requested by the Required Lenders and (b) the Lenders have provided to
the Agent such additional indemnities and assurances in accordance with their respective Commitment
Percentages against expenses and liabilities as the Agent may reasonably request, shall proceed to
exercise all or any legal and equitable and other rights or remedies as it may have;
provided, however, that unless and until the Agent shall have received such
directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default or Event of Default as it shall deem to be in the best
interests of the Lenders. Without limiting the generality of the foregoing, if Agent reasonably
determines payment is in the best interest of all the Lenders, Agent may without the approval of
the Lenders pay taxes and insurance premiums and spend money for maintenance, repairs or other
expenses which may be necessary to be incurred, and Agent shall promptly thereafter notify the
Lenders of such action. Each Lender shall, within thirty (30) days of request therefor, pay to the
Agent its Commitment Percentage of the reasonable costs incurred by the Agent in taking any such
actions hereunder to the extent that such costs shall not be promptly reimbursed to the Agent by
the Borrowers or out of the Collateral within such period with

95

 

respect to the Mortgaged Properties. The Required Lenders may direct the Agent in writing as
to the method and the extent of any such exercise, the Lenders hereby agreeing to indemnify and
hold the Agent harmless in accordance with their respective Commitment Percentages from all
liabilities incurred in respect of all actions taken or omitted in accordance with such directions,
except to the extent that any of the same shall be directly caused by the Agent’s willful
misconduct or gross negligence as finally determined by a court of competent jurisdiction after the
expiration of all applicable appeal periods, provided that the Agent need not comply with
any such direction to the extent that the Agent reasonably believes the Agent’s compliance with
such direction to be unlawful in any applicable jurisdiction or commercially unreasonable under the
UCC as enacted in any applicable jurisdiction.

     §14.11 Bankruptcy. In the event a bankruptcy or other insolvency proceeding is commenced by
or against any Borrower with respect to the Obligations, the Agent shall have the sole and
exclusive right to file and pursue a joint proof claim on behalf of all Lenders. Any votes with
respect to such claims or otherwise with respect to such proceedings shall be subject to the vote
of the Required Lenders or all of the Lenders as required by this Agreement. Each Lender
irrevocably waives its right to file or pursue a separate proof of claim in any such proceedings
unless Agent fails to file such claim within thirty (30) days after receipt of written notice from
the Lenders requesting that Agent file such proof of claim.

     §14.12 Request for Agent Action. Agent and the Lenders acknowledge that in the ordinary
course of business of the Borrowers, (a) Borrowers will enter into leases or rental agreements
covering Mortgaged Properties that may require the execution of a Subordination, Attornment and
Non-Disturbance Agreement in favor of the tenant thereunder, (b) a Mortgaged Property may be
subject to a Taking, (c) a Borrower may desire to enter into easements or other agreements
affecting the Mortgaged Properties, or take other actions or enter into other agreements in the
ordinary course of business which similarly require the consent, approval or agreement of the
Agent. In connection with the foregoing, the Lenders hereby expressly authorize the Agent to (w)
execute and deliver to the Borrowers Subordination, Attornment and Non-Disturbance Agreements with
any tenant under a Lease upon such terms as Agent in its good faith judgment determines are
appropriate (Agent in the exercise of its good faith judgment may agree to allow some or all of the
casualty, condemnation, restoration or other provisions of the applicable Lease to control over the
applicable provisions of the Loan Documents), (x) execute releases of liens in connection with any
Taking, (y) execute consents or subordinations in form and substance satisfactory to Agent in
connection with any easements or agreements affecting the Mortgaged Property, or (z) execute
consents, approvals, or other agreements in form and substance satisfactory to the Agent in
connection with such other actions or agreements as may be necessary in the ordinary course of
Borrowers’ business.

     §14.13 Reliance by Agent. The Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument,
document or other writing (including any electronic message, Internet or intranet website posting
or other distribution) believed by it to be genuine and to have been signed, sent or otherwise
authenticated by an Authorized Officer. The Agent also may rely upon any statement made to it
orally or by telephone and believed by it to have been made by the proper Person, and shall not
incur any liability for relying thereon. In determining compliance with any condition hereunder to
the making of a Loan, that by its terms must be fulfilled to the satisfaction of a Lender, the

96

 

Agent may presume that such condition is satisfactory to such Lender unless the Agent shall
have received notice to the contrary from such Lender prior to the making of such Loan. The Agent
may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and
other experts selected by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts.

     §14.14 Approvals. If consent is required for some action under this Agreement, or except as
otherwise provided herein an approval of the Lenders, the Majority Lenders or the Required Lenders
is required or permitted under this Agreement, each Lender agrees to give the Agent, within ten
(10) days of receipt of the request for action together with all reasonably requested information
related thereto (or such lesser period of time required by the terms of the Loan Documents), notice
in writing of approval or disapproval (collectively “Directions”) in respect of any action
requested or proposed in writing pursuant to the terms hereof. To the extent that any Lender does
not approve any recommendation of Agent, such Lender shall in such notice to Agent describe the
actions that would be acceptable to such Lender. If consent is required for the requested action,
any Lender’s failure to respond to a request for Directions within the required time period shall
be deemed to constitute a Direction to take such requested action. In the event that any
recommendation is not approved by the requisite number of Lenders and a subsequent approval on the
same subject matter is requested by Agent, then for the purposes of this paragraph each Lender
shall be required to respond to a request for Directions within five (5) Business Days of receipt
of such request. Agent and each Lender shall be entitled to assume that any officer of the other
Lenders delivering any notice, consent, certificate or other writing is authorized to give such
notice, consent, certificate or other writing unless Agent and such other Lenders have otherwise
been notified in writing.

     §14.15 Borrowers Not Beneficiary. Except for the provisions of §14.9 relating to the
appointment of a successor Agent, the provisions of this §14 are solely for the benefit of the
Agent and the Lenders, may not be enforced by the Borrowers, and except for the provisions of
§14.9, may be modified or waived without the approval or consent of the Borrowers.

     §14.16 Defaulting Lenders.

     (a) Notwithstanding anything to the contrary contained in this Agreement, if any Lender
becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender,
to the extent permitted by applicable Legal Requirements:

          (i) That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent
with respect to this Agreement shall be restricted as set forth in §27.

          (ii) Any payment of principal, interest, fees or other amounts received by the Agent for the
account of that Defaulting Lender (whether voluntary or mandatory, at maturity, or otherwise, and
including any amounts made available to the Agent by that Defaulting Lender pursuant to §13), shall
be applied at such time or times as may be determined by the Agent as follows: first, to the
payment of any amounts owing by that Defaulting Lender to the Agent hereunder; second, to the
payment on a pro rata basis of any amounts owing by that Defaulting Lender to the Issuing Lender or
Swing Loan Lender hereunder; third, if so determined by the Agent or requested by the Issuing
Lender or Swing Loan Lender, to be held as cash collateral for

97

 

future funding obligations of that Defaulting Lender of any participation in any Swing Loan or
Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default
exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund
its portion thereof as required by this Agreement, as determined by the Agent; fifth, if so
determined by the Agent and the Borrower, to be held in a non-interest bearing deposit account and
released in order to satisfy obligations of that Defaulting Lender to fund Loans under this
Agreement; sixth, to the payment of any amounts owing to the Lenders, the Issuing Lender or Swing
Loan Lender as a result of any judgment of a court of competent jurisdiction obtained by any
Lender, the Issuing Lender or Swing Loan Lender against that Defaulting Lender as a result of that
Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default
or Event of Default exists or non-defaulting Lenders have been paid in full all amounts then due,
to the payment of any amounts owing to the Borrower as a result of any judgment of a court of
competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that
Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to that Defaulting
Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x)
such payment is a payment of the principal amount of any Loans or Letter of Credit Liabilities in
respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such
Loans or Letter of Credit Liabilities were made at a time when the conditions set forth in §11 were
satisfied or waived, such payment shall be applied solely to pay the Loans of, and Letter of Credit
Liabilities owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the
payment of any Loans of, or Letter of Credit Liabilities owed to, that Defaulting Lender. Any
payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or
held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this
§14.16(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender
irrevocably consents hereto.

          (iii) That Defaulting Lender (x) shall not be entitled to receive any facility unused fee
pursuant to §2.3 for any period during which that Lender is a Defaulting Lender (and the Borrower
shall not be required to pay any such fee that otherwise would have been required to have been paid
to that Defaulting Lender) and (y) shall be limited in its right to receive Letter of Credit Fees
as provided in §2.10(e).

          (iv) During any period in which there is a Defaulting Lender, for purposes of computing the
amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations
in Letters of Credit or Swing Loans pursuant to §2.5 and/or 2.10, the “Commitment Percentage” of
each non-Defaulting Lender shall be computed without giving effect to the Commitment of that
Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only
if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default
exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or
fund participations in Letters of Credit and Swing Loans shall not exceed the positive difference,
if any, of (1) the Commitment of that non-Defaulting Lender minus (2) the aggregate
Outstanding of the Loans of and Letter of Credit Liabilities held by that Lender.

          (v) During any period that a Lender is a Defaulting Lender, the Borrower may, by giving
written notice thereof to the Agent, such Defaulting Lender, and the other Lenders, demand that
such Defaulting Lender assign its Commitment to an Eligible Assignee

98

 

subject to and in accordance with the provisions of §18.1. No party hereto shall have any
obligation whatsoever to initiate any such replacement or to assist in finding an Eligible
Assignee. In addition, any Lender who is not a Defaulting Lender may, but shall not be obligated,
in its sole discretion, to acquire the face amount of all or a portion of such Defaulting Lender’s
Commitment via an assignment subject to and in accordance with the provisions of §18.1. No such
assignment shall be effective unless and until, in addition to the other conditions thereto set
forth herein, the parties to the assignment shall make such additional payments to the Agent in an
aggregate amount sufficient with any applicable amounts held pursuant to the immediately preceding
subsection (f), upon distribution thereof as appropriate (which may be outright payment, purchases
by the assignee of participations or subparticipations, or other compensating actions, including
funding, with the consent of the Borrower and the Agent, the applicable pro rata share of Loans
previously requested but not funded by the Defaulting Lender, to each of which the applicable
assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment
liabilities then owed by such Defaulting Lender to the Agent, the Issuing Lender or any Lender
hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) such Defaulting
Lender’s full pro rata share of all Loans and participations in Letters of Credit and Swing Loans.
Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any
Defaulting Lender hereunder shall become effective under any Legal Requirement without compliance
with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a
Defaulting Lender for all purposes of this Agreement until such compliance occurs.

          (b) Defaulting Lender Cure. If the Borrower, the Agent, Swing Loan Lender and the
Issuing Lender agree in writing in their sole discretion that a Defaulting Lender should no longer
be deemed to be a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of
the effective date specified in such notice and subject to any conditions set forth therein (which
may include arrangements with respect to any Cash Collateral), that Lender will, to the extent
applicable, purchase that portion of outstanding Loans of the other Lenders or take such other
actions as the Agent may determine to be necessary to cause the Loans and funded and unfunded
participations in Letters of Credit and Swing Loans to be held on a pro rata basis by the Lenders
in accordance with their Applicable Percentages (without giving effect to §14.16(a)(iv)), whereupon
that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made
retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while
that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise
expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will
constitute a waiver or release of any claim of any party hereunder arising from that Lender’s
having been a Defaulting Lender.

§15. EXPENSES.

     The Borrowers agree to pay, to the extent incurred by Agent (a) the reasonable costs of
producing and reproducing this Agreement, the other Loan Documents and the other agreements and
instruments mentioned herein, (b) any recording, mortgage, documentary or intangibles taxes in

thereof after the occurrence of a Default or Event of Default and (ii) any litigation, proceeding
or dispute whether arising hereunder or otherwise, in any way related to the Agent’s or any of the

similar system for the dissemination and sharing of documents and information in connection with
the Loans. The covenants of this §15 shall survive the repayment of the Loans and the termination

§16. INDEMNIFICATION.

     The Borrowers, jointly and severally, agree to indemnify and hold harmless the Agent, the
Lenders and the Arrangers and each director, officer, employee, agent and Affiliate thereof and
Person who controls the Agent or any Lender or the Arrangers against any and all claims, actions
and suits, whether groundless or otherwise, and from and against any and all liabilities, losses,

agree to pay promptly the reasonable fees and expenses of such counsel. If, and to the extent that
the obligations of the Borrowers under this §16 are unenforceable for any reason, the Borrowers
hereby agree to make the maximum contribution to the payment in satisfaction of such obligations
which is permissible under applicable law. The provisions of this §16 shall survive the repayment
of the Loans and the termination of the obligations of the Lenders hereunder.

§17. SURVIVAL OF COVENANTS, ETC.

     All covenants, agreements, representations and warranties made herein, in the Notes, in any of
the other Loan Documents or in any documents or other papers delivered by or on behalf of the
Borrowers or any of their respective Subsidiaries pursuant hereto or thereto shall be deemed to
have been relied upon by the Lenders and the Agent, notwithstanding any investigation heretofore or

herein contemplated, and shall continue in full force and effect so long as any amount due under
this Agreement or the Notes or any of the other Loan Documents remains outstanding or any Letters
of Credit remain outstanding or any Lender has any obligation to make any Loans or issue any
Letters of Credit. The indemnification obligations of the Borrowers provided herein and in the
other Loan Documents shall survive the full repayment of amounts due and the termination of the
obligations of the Lenders hereunder and thereunder to the extent provided herein and therein. All
statements contained in any certificate delivered to any Lender or the Agent at any time by or on
behalf of the Borrowers or any of their respective Subsidiaries pursuant hereto or in connection

§18. ASSIGNMENT AND PARTICIPATION.

     §18.1 Conditions to Assignment by Lenders. Except as provided herein, each Lender may assign
to one or more Eligible Assignee all or a portion of its interests, rights and obligations under
this Agreement (including all or a portion of its Commitment Percentage and Commitment and the same
portion of the Loans at the time owing to it and the Notes held by it); provided that (a)
the Agent and the Issuing Lender shall have each given its prior written consent to such
assignment, which consent shall not be unreasonably withheld or delayed (b) each such assignment
shall be of a constant, and not a varying, percentage of all the assigning Lender’s

101

 

rights and obligations under this Agreement with respect to the Revolving Credit Commitment in
the event an interest in the Revolving Credit Loans is assigned, (c) the parties to such assignment
shall execute and deliver to the Agent, for recording in the Register (as hereinafter defined) an
Assignment and Acceptance Agreement in the form of Exhibit H annexed hereto, together with
any Notes subject to such assignment, (d) in no event shall any assignment be to any Person
controlling, controlled by or under common control with, or which is not otherwise free from
influence or control by, any Borrower or REIT, (e) such assignee shall acquire an interest in the
Loans of not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof (or if
less, the remaining Loans of the assignor), unless waived by the Agent, and so long as no Default
or Event of Default exists hereunder, Parent Borrower, and (f) such assignee shall be subject to
the terms of any intercreditor agreement among the Lenders and the Agent. Upon execution,
delivery, acceptance and recording of such Assignment and Acceptance Agreement, (i) the assignee
thereunder shall be a party hereto and all other Loan Documents executed by the Lenders and, to the
extent provided in such Assignment and Acceptance Agreement, have the rights and obligations of a
Lender hereunder, (ii) the assigning Lender shall, upon payment to the Agent of the registration
fee referred to in §18.2, be released from its obligations under this Agreement arising after the
effective date of such assignment with respect to the assigned portion of its interests, rights and
obligations under this Agreement, and (iii) the Agent may unilaterally amend Schedule 1.1
to reflect such assignment. In connection with each assignment, the assignee shall represent and
warrant to the Agent, the assignor and each other Lender as to whether such assignee is
controlling, controlled by, under common control with or is not otherwise free from influence or
control by, the Borrowers and REIT.

     §18.2 Register. The Agent shall maintain on behalf of the Borrowers a copy of each assignment
delivered to it and a register or similar list (the “Register”) for the recordation of the names
and addresses of the Lenders and the Commitment Percentages of and principal amount of and interest
on 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 Borrowers, the Agent and the Lenders may
treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes,
notwithstanding notice to the contrary. The Register shall be available for inspection by the
Borrowers and the Lenders at any reasonable time and from time to time upon reasonable prior
notice. Upon each such recordation, the assigning Lender agrees to pay to the Agent a registration
fee in the sum of $3,500.

     §18.3 New Notes. Upon its receipt of an Assignment and Acceptance Agreement executed by the
parties to such assignment, together with each Note subject to such assignment, the Agent shall
record the information contained therein in the Register. Within five (5) Business Days after
receipt of notice of such assignment from Agent, the Borrowers, at their own expense, shall execute
and deliver to the Agent, in exchange for each surrendered Note, a new Note (if requested by the
subject Lender) to the order of such assignee in an amount equal to the amount assigned to such
assignee pursuant to such Assignment and Acceptance Agreement and, if the assigning Lender has
retained some portion of its obligations hereunder, a new Note to the order of the assigning Lender
in an amount equal to the amount retained by it hereunder. Such new Notes shall provide that they
are replacements for the surrendered Notes, shall be in an aggregate principal amount equal to the
aggregate principal amount of the surrendered Notes, shall be dated the effective date of such
Assignment and Acceptance Agreement and shall

102

 

otherwise be in substantially the form of the assigned Notes. The surrendered Notes shall be
canceled and returned to the Borrowers.

     §18.4 Participations. Each Lender may sell participations to one or more Lenders or other
entities in all or a portion of such Lender’s rights and obligations under this Agreement and the
other Loan Documents; provided that (a) any such sale or participation shall not affect the
rights and duties of the selling Lender hereunder, (b) such participation shall not entitle such
participant to any rights or privileges under this Agreement or any Loan Documents, including
without limitation, rights granted to the Lenders under §4.8, §4.9 and §4.10, (c) such
participation shall not entitle the participant to the right to approve waivers, amendments or
modifications, (d) such participant shall have no direct rights against the Borrowers, (e) such
sale is effected in accordance with all applicable laws, and (f) such participant shall not be a
Person controlling, controlled by or under common control with, or which is not otherwise free from
influence or control by any of the Borrowers; provided, however, such Lender may
agree with the participant that it will not, without the consent of the participant, agree to (i)
increase, or extend the term or extend the time or waive any requirement for the reduction or
termination of, such Lender’s Commitment, (ii) extend the date fixed for the payment of principal
of or interest on the Loans or portions thereof owing to such Lender (other than pursuant to an
extension of the Revolving Credit Maturity Date pursuant to §2.12), (iii) reduce the amount of any
such payment of principal, (iv) reduce the rate at which interest is payable thereon or (v) release
any Borrower (except as otherwise permitted under §5.4, §5.6 or §5.7). Each Lender that sells a
participation shall, acting solely for this purpose as an agent of the Borrowers, maintain at one
of its offices a register for the recordation of the names and addresses of its participants, and
the amount and terms of its participations (the “Participant Register”). The entries in the
Participant Register shall be conclusive, and such Lender and the Agent shall treat each Person
whose name is recorded in the Participant Register pursuant to the terms hereof as the owner of
such participation for all purposes of this Agreement, notwithstanding notice to the contrary.

     §18.5 Pledge by Lender. Any Lender may at any time pledge all or any portion of its interest
and rights under this Agreement (including all or any portion of its Note) to any of the twelve
Federal Reserve Banks organized under §4 of the Federal Reserve Act, 12 U.S.C. §341 or to such
other Person as the Agent may approve to secure obligations of such lenders. No such pledge or the
enforcement thereof shall release the pledgor Lender from its obligations hereunder or under any of
the other Loan Documents.

     §18.6 No Assignment by Borrowers. The Borrowers shall not assign or transfer any of their
rights or obligations under this Agreement without the prior written consent of each of the
Lenders.

     §18.7 Disclosure. Borrowers, at no cost or expense, agree to promptly cooperate with any
Lender in connection with any proposed permitted assignment or participation of all or any portion
of its Commitment. The Borrowers agree that in addition to disclosures made in accordance with
standard banking practices any Lender may disclose information, subject to such proposed
participant entering into a confidentiality agreement providing substantially the same protection
to the Borrowers as this Agreement, obtained by such Lender pursuant to this Agreement to assignees
or participants and potential assignees or participants hereunder, subject to the provisions of
this §18.7. Each Lender agrees for itself that it shall in accordance with its

103

 

customary procedures hold confidential all non-public information obtained from Borrowers that
has been identified in writing as confidential by any of them, and shall use reasonable efforts in
accordance with its customary procedures to not disclose such information to any other Person, it
being understood and agreed that, notwithstanding the foregoing, a Lender may make (a) disclosures
to its participants (provided such Persons are advised of the provisions of this §18.7 and sign a
confidentiality agreement reasonably acceptable to Borrower), (b) disclosures to its directors,
officers, employees, Affiliates, accountants, appraisers, legal counsel and other professional
advisors of such Lender (provided that such Persons who are not employees of such Lender are
advised of the provision of this §18.7 and sign a confidentiality agreement reasonably acceptable
to Borrower), (c) disclosures customarily provided or reasonably required by any potential or
actual bona fide assignee, transferee or participant or their respective directors, officers,
employees, Affiliates, accountants, appraisers, legal counsel and other professional advisors in
connection with a potential or actual assignment or transfer by such Lender of any Loans or any
participations therein (provided such Persons are advised of the provisions of this §18.7 and sign
a confidentiality agreement reasonably acceptable to Borrower), (d) disclosures to bank regulatory
authorities or self-regulatory bodies with jurisdiction over such Lender, or (e) disclosures
required or requested by any other governmental authority or representative thereof or pursuant to
legal process; provided that, unless specifically prohibited by applicable law or court order, each
Lender shall notify Borrowers of any request by any governmental authority or representative
thereof prior to disclosure (other than any such request in connection with any examination of such
Lender by such government authority) for disclosure of any such non-public information prior to
disclosure of such information. In addition, each Lender may make disclosure of such information
to any contractual counterparty in swap agreements or such contractual counterparty’s professional
advisors (so long as such contractual counterparty or professional advisors agree to be bound by
the provisions of this §18.7 and sign a confidentiality agreement reasonably acceptable to
Borrower). Non-public information shall not include any information which is or subsequently
becomes publicly available other than as a result of a disclosure of such information by a Lender,
or prior to the delivery to such Lender is within the possession of such Lender if such information
is not known by such Lender to be subject to another confidentiality agreement with or other
obligations of secrecy to the Borrowers, or is disclosed with the prior approval of Borrowers.
Nothing herein shall prohibit the disclosure of non-public information to the extent necessary to
enforce the Loan Documents.

     §18.8 Titled Agents. The Titled Agents shall not have any additional rights or obligations
under the Loan Documents, except for those rights, if any, as a Lender.

Lenders acknowledge that, pursuant to such activities, KeyBank or its Affiliates may receive
information regarding such Persons (including information that may be subject to confidentiality
obligations in favor of such Person) and acknowledge that the Agent shall be under no obligation to
provide such information to them.

§27. CONSENTS, AMENDMENTS, WAIVERS, ETC.

     Except as otherwise expressly provided in this Agreement, any consent or approval required or
permitted by this Agreement may be given, and any term of this Agreement or of any other instrument
related hereto or mentioned herein may be amended, and the performance or observance by the
Borrowers of any terms of this Agreement or such other instrument or the continuance of any Default

retroactively or prospectively) with, but only with, the written consent of the Required Lenders.
Notwithstanding the foregoing, none of the following may occur without the written consent of each
Lender adversely affected thereby: (a) a reduction in the rate of interest on the Notes (other
than a reduction or waiver of default interest); (b) an increase in the amount of the Commitments
of the Lenders (except as provided in §2.11 and §18.1); (c) a forgiveness, reduction or waiver of
the principal of any unpaid Loan or any interest thereon or fee payable under the Loan Documents;
(d) a change in the amount of any fee payable to a Lender hereunder; (e) the postponement of any

action. The provisions of §14 may not be amended without the written consent of the Agent.
There shall be no amendment, modification or waiver of any provision in the Loan Documents with
respect to Swing Loans without the consent of the Swing Loan Lender, nor any amendment,
modification or waiver of any provision in the Loan Documents with respect to Letters of Credit
without the consent of the Issuing Lender. No waiver shall extend to or affect any obligation not

on the part of the Agent or any Lender in exercising any right shall operate as a waiver thereof or
otherwise be prejudicial thereto. Notwithstanding anything to the contrary herein, no Defaulting
Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder

jurisdiction, and shall not in any manner affect such clause or provision in any other
jurisdiction, or any other clause or provision of this Agreement in any jurisdiction.

the Borrowers under this Agreement and the other Loan Documents.

CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

BETWEEN THE PARTIES ARE SET FORTH BELOW.

or mutilation of any Note, and in the case of any such loss, theft or destruction, upon delivery of

upon surrender and cancellation of the applicable Note, Borrowers will execute and deliver, in lieu
thereof, a replacement Note, identical in form and substance to the applicable Note and dated as of

assigns, and no other Person shall be a direct or indirect legal beneficiary of, or have any direct
or indirect cause of action or claim in connection with, this Agreement or any of the other Loan
Documents. All conditions to the performance of the obligations of the Agent and the Lenders under
this Agreement, including the obligation to make Loans and issue Letters of Credit, are imposed
solely and exclusively for the benefit of the Agent and the Lenders and no other Person shall have
standing to require satisfaction of such conditions in accordance with their terms or be entitled
to assume that the Agent and the Lenders will refuse to make Loans or issue Letters of Credit in
the absence of strict compliance with any or all thereof and no other Person shall, under any
circumstances, be deemed to be a beneficiary of such conditions, any and all of which may be freely
waived in whole or in part by the Agent and the Lenders at any time if in their sole discretion
they deem it desirable to do so. In particular, the Agent and the Lenders make no representations
and assume no obligations as to third parties concerning the quality of the construction by the
Borrowers or any of their Subsidiaries of any development or the absence therefrom of defects.

§33. PATRIOT ACT.

Borrowers that, pursuant to the requirements of the Patriot Act, it is required to obtain, verify

and other information that will allow such Lender or the Agent, as applicable, to identify
Borrowers in accordance with the Patriot Act.

§34. [Intentionally Omitted.]

a joint borrowing basis as set forth in this Agreement is solely as an accommodation to the
Borrowers and at their request. Accordingly, the Agent and the Lenders are entitled to

110

 

rely, and shall be exonerated from any liability for relying upon, any Loan Request or Letter
of Credit Request or any other request or communication made by a purported officer of any Borrower
without the need for any consent or other authorization of any other Borrower and upon any
information or certificate provided on behalf of any Borrower by a purported officer of such
Borrower, and any such request or other action shall be fully binding on each Borrower as if made
by it.

     §36.3 Waiver of Automatic or Supplemental Stay. Each of the Borrowers represents, warrants
and covenants to the Lenders and Agent that in the event of the filing of any voluntary or
involuntary petition in bankruptcy by or against the other of the Borrowers at any time following
the execution and delivery of this Agreement, none of the Borrowers shall seek a supplemental stay
or any other relief, whether injunctive or otherwise, pursuant to Section 105 of the Bankruptcy
Code or any other provision of the Bankruptcy Code, to stay, interdict, condition, reduce or
inhibit the ability of the Lenders or Agent to enforce any rights it has by virtue of this
Agreement, the Loan Documents, or at law or in equity, or any other rights the Lenders or Agent
has, whether now or hereafter acquired, against the other Borrowers or against any property owned
by such other Borrowers.

     §36.4 Waiver of Defenses. To the extent permitted by applicable law, each of the Borrowers
hereby waives and agrees not to assert or take advantage of any defense based upon:

          (a) Any right to require Agent or the Lenders to proceed against the other Borrowers or any
other Person or to proceed against or exhaust any security held by Agent or the Lenders at any time
or to pursue any other remedy in Agent’s or any Lender’s power or under any other agreement before
proceeding against a Borrower hereunder or under any other Loan Document;

          (b) The defense of the statute of limitations in any action hereunder or the payment or
performance of any of the Obligations;

          (c) Any defense that may arise by reason of the incapacity, lack of authority, death or
disability of any other Person or Persons or the failure of Agent or any Lender to file or enforce
a claim against the estate (in administration, bankruptcy or any other proceeding) of any other
Person or Persons;

          (d) Any failure on the part of Agent or any Lender to ascertain the extent or nature of any
Collateral or any insurance or other rights with respect thereto, or the liability of any party
liable under the Loan Documents or the obligations evidenced or secured thereby;

          (e) Demand, presentment for payment, notice of nonpayment, protest, notice of protest and all
other notices of any kind (except for such notices as are specifically required to be provided to
Borrowers pursuant to the Loan Documents), or the lack of any thereof, including, without limiting
the generality of the foregoing, notice of the existence, creation or incurring of any new or
additional indebtedness or obligation or of any action or non-action on the part of any Borrower,
Agent, any Lender, any endorser or creditor of Borrowers or on the part of any other Person
whomsoever under this or any other instrument in connection with any obligation or evidence of
indebtedness held by Agent or any Lender;

111

 

          (f) Any defense based upon an election of remedies by Agent or any Lender, including any
election to proceed by judicial or nonjudicial foreclosure of any security, whether real property
or personal property security, or by deed in lieu thereof, and whether or not every aspect of any
foreclosure sale is commercially reasonable, or any election of remedies, including remedies
relating to real property or personal property security, which destroys or otherwise impairs the
subrogation rights of a Borrower or the rights of a Borrower to proceed against the other Borrowers
for reimbursement, or both;

          (g) Any right or claim of right to cause a marshaling of the assets of Borrowers;

          (h) Any principle or provision of law, statutory or otherwise, which is or might be in
conflict with the terms and provisions of this Agreement;

          (i) Any duty on the part of Agent or any Lender to disclose to Borrowers any facts Agent or
any Lender may now or hereafter know about Borrowers or the Collateral, regardless of whether Agent
or any Lender has reason to believe that any such facts materially increase the risk beyond that
which each Borrower intends to assume or has reason to believe that such facts are unknown to
Borrowers or has a reasonable opportunity to communicate such facts to Borrowers, it being
understood and agreed that each Borrower is fully responsible for being and keeping informed of the
financial condition of the other Borrowers, of the condition of the Mortgaged Property or the
Collateral and of any and all circumstances bearing on the risk that liability may be incurred by
Borrowers hereunder and under the other Loan Documents;

          (j) Any inaccuracy of any representation or other provision contained in any Loan Document;

          (k) Subject to compliance with the provisions of this Agreement, any sale or assignment of the
Loan Documents, or any interest therein;

          (l) Subject to compliance with the provisions of this Agreement, any sale or assignment by a
Borrower or any other Person of any Collateral, or any portion thereof or interest therein, not
consented to by Agent or any Lender;

          (m) Any invalidity, irregularity or unenforceability, in whole or in part, of any one or more
of the Loan Documents;

          (n) Any lack of commercial reasonableness in dealing with the Collateral;

          (o) Any deficiencies in the Collateral or any deficiency in the ability of Agent or any Lender
to collect or to obtain performance from any Persons now or hereafter liable for the payment and
performance of any obligation hereby guaranteed;

          (p) An assertion or claim that the automatic stay provided by 11 U.S.C. §362 (arising upon the
voluntary or involuntary bankruptcy proceeding of the other Borrowers) or any other stay provided
under any other debtor relief law (whether statutory, common law, case law or otherwise) of any
jurisdiction whatsoever, now or hereafter in effect, which may be or become applicable, shall
operate or be interpreted to stay, interdict, condition, reduce or inhibit the ability

112

 

of Agent or any Lender to enforce any of its rights, whether now or hereafter required, which
Agent or any Lender may have against a Borrower or the Collateral owned by it;

          (q) Any modifications of the Loan Documents or any obligation of Borrowers relating to the
Loan by operation of law or by action of any court, whether pursuant to the Bankruptcy Code, or any
other debtor relief law (whether statutory, common law, case law or otherwise) of any jurisdiction
whatsoever, now or hereafter in effect, or otherwise;

          (r) Any release of a Borrower or of any other Person from performance or observance of any of
the agreements, covenants, terms or conditions contained in any of the Loan Documents by operation
of law, Agent’s or the Lenders’ voluntary act or otherwise;

          (s) Any action, occurrence, event or matter consented to by Borrowers under any provision
hereof, or otherwise;

          (t) The dissolution or termination of existence of any Borrower;

          (u) Either with or without notice to Borrowers, any renewal, extension, modification,
amendment or another changes in the Obligations, including but not limited to any material
alteration of the terms of payment or performance of the Obligations;

          (v) Any defense of Borrowers, including without limitation, the invalidity, illegality or
unenforceability of any of the Obligations; or

          (w) To the fullest extent permitted by law, any other legal, equitable or surety defenses
whatsoever to which Borrowers might otherwise be entitled, it being the intention that the
obligations of Borrowers hereunder are absolute, unconditional and irrevocable.

     §36.5 Waiver. Each of the Borrowers waives, to the fullest extent that each may lawfully so
do, the benefit of all appraisement, valuation, stay, extension, homestead, exemption and
redemption laws which such Person may claim or seek to take advantage of in order to prevent or
hinder the enforcement of any of the Loan Documents or the exercise by Lenders or Agent of any of
their respective remedies under the Loan Documents and, to the fullest extent that the Borrowers
may lawfully so do, such Person waives any and all right to have the assets comprised in the
security intended to be created by the Security Documents (including, without limitation, those
assets owned by the other of the Borrowers) marshaled upon any foreclosure of the lien created by
such Security Documents. Each of the Borrowers further agrees that the Lenders and Agent shall be
entitled to exercise their respective rights and remedies under the Loan Documents or at law or in
equity in such order as they may elect. Without limiting the foregoing, each of the Borrowers
further agrees that upon the occurrence of an Event of Default, the Lenders and Agent may exercise
any of such rights and remedies without notice to either of the Borrowers except as required by law
or the Loan Documents and agrees that neither the Lenders nor Agent shall be required to proceed
against the other of the Borrowers or any other Person or to proceed against or to exhaust any
other security held by the Lenders or Agent at any time or to pursue any other remedy in Lender’s
or Agent’s power or under any of the Loan Documents before proceeding against a Borrower or its
assets under the Loan Documents.

113

 

     §36.6 Subordination. So long as the Loans are outstanding, each of the Borrowers hereby
expressly waives any right of contribution from or indemnity against the other, whether at law or
in equity, arising from any payments made by such Person pursuant to the terms of this Agreement or
the Loan Documents, and each of the Borrowers acknowledges that it has no right whatsoever to
proceed against the other for reimbursement of any such payments. In connection with the
foregoing, each of the Borrowers expressly waives any and all rights of subrogation to the Lenders
or Agent against the other of the Borrowers, and each of the Borrowers hereby waives any rights to
enforce any remedy which the Lenders or Agent may have against the other of the Borrowers and any
rights to participate in any Collateral or any other assets of the other Borrowers. In addition to
and without in any way limiting the foregoing, each of the Borrowers hereby subordinates any and
all indebtedness it may now or hereafter owe to such other Borrowers to all indebtedness of the
Borrowers to the Lenders and Agent, and agrees with the Lenders and Agent that neither of the
Borrowers shall claim any offset or other reduction of such Borrower’s obligations hereunder
because of any such indebtedness and shall not take any action to obtain any of the Collateral or
any other assets of the other Borrowers.

     §36.7 Waiver of Rights Under Anti-Deficiency Rules. Without limiting any other provision of
this §36, each Borrower understands and acknowledges that, if the Agent forecloses judicially or
nonjudicially against any real property Collateral for the Obligations, such foreclosure could
impair or destroy any right or ability that such Borrower may have to seek reimbursement,
contribution, or indemnification for any amounts paid by such Borrower under this Agreement. Each
Borrower further understands and acknowledges that in the absence of this waiver such potential
impairment or destruction of such Borrower’s rights, if any, may entitle such Borrower to assert a
defense to this Agreement based on California Code of Civil Procedure §580d as interpreted in
Union Bank v. Gradsky, (1968) 265 CA 2d 40, 71 CR 64, on the grounds, among others, that
the Agent or the Lenders should be estopped from pursuing such Borrower because their election to
foreclose may have impaired or destroyed such subrogation, reimbursement, contribution, or
indemnification rights of such Borrower. By execution of this Agreement, each Borrower
intentionally, freely, irrevocably, and unconditionally: (i) waives and relinquishes that defense
and agrees that such Borrower will be liable under this Agreement even though the Agent has
foreclosed judicially or nonjudicially against any real or personal property Collateral for the
Obligations; (ii) agrees that such Borrower will not assert that defense in any action or
proceeding which the Agent or the Lenders may bring to enforce this Agreement; and (iii)
acknowledges and agrees that until the Obligations have been indefeasibly paid in full, the rights
and defenses waived by such Borrower in this Agreement include any right or defense that such
Borrower may have or be entitled to assert based on or arising out of California Civil Code §2848.

     §36.8 Further Waivers. Each Borrower intentionally, freely, irrevocably and unconditionally
waives and relinquishes all rights which may be available to it under any provision of California
law or under any California judicial decision, including, without limitation, Section 580a and
726(b) of the California Code of Civil Procedure, to limit the amount of any deficiency judgment or
other judgment which may be obtained against such Borrower under this Agreement to not more than
the amount by which the unpaid Obligations exceeds the fair market value or fair value of any real
or personal property securing the Obligations, including, without limitation, all rights to an
appraisement of, judicial or other hearing on, or other determination of the value of said
property. Each Borrower acknowledges

114

 

and agrees that, as a result of the foregoing waiver, the Agent or the Lenders may be entitled
to recover from such Borrower an amount which, when combined with the value of any real or personal
property foreclosed upon by the Agent (or the proceeds of the sale of which have been received by
the Agent and the Lenders) and any sums collected by the Agent and the Lenders from any other
Borrower, the other guarantors or other Persons, might exceed the amount of the Obligations.

§37. ACKNOWLEDGMENT OF BENEFITS; EFFECT OF AVOIDANCE PROVISIONS.

          (a) Without limiting any other provision of §36, each Subsidiary Borrower acknowledges that it
has received, or will receive, significant financial and other benefits, either directly or
indirectly, from the proceeds of the Loans made by the Lenders to the Borrowers pursuant to this
Agreement; that the benefits received by such Subsidiary Borrower are reasonably equivalent
consideration for such Subsidiary Borrower’s execution of this Agreement and the other Loan
Documents to which it is a party; and that such benefits include, without limitation, the access to
capital afforded to the Borrowers pursuant to this Agreement from which the activities of such
Subsidiary Borrower will be supported, the refinancing of certain existing indebtedness of such
Subsidiary Borrower secured by such Subsidiary Borrower’s Mortgaged Property from the proceeds of
the Loans, and the ability to refinance that indebtedness at a lower interest rate and otherwise on
more favorable terms than would be available to it if the Mortgaged Property owned by such
Subsidiary Borrower were being financed on a stand-alone basis and not as part of a pool of assets
comprising the security for the Obligations. Each Subsidiary Borrower is executing this Agreement
and the other Loan Documents in consideration of those benefits received by it and each Subsidiary
Borrower desires to enter into an allocation and constribution agreement with each other Subsidiary
Borrower as set forth in this §37 and agrees to subordinate and subrogate any rights or claims it
may have against other Subsidiary Borrowers as and to the extent set forth in §36.

          (b) In the event any one or more Subsidiary Borrowers (any such Subsidiary Borrower, a
“Funding Borrower”) is deemed to have paid an amount in excess of the principal amount
attributable to it (such principal amount, the “Allocable Principal Balance”) (any deemed
payment in excess of the applicable Allocable Principal Balance, a “Contribution”) as a
result of (a) such Funding Borrower’s payment of and/or performance on the Obligations and/or (b)
Agent’s and/or any Lender’s realization on the Collateral owned by such Funding Borrower (whether
by foreclosure, deed in lieu of foreclosure, private sale or other means), then after payment in
full of the Loans and the satisfaction of all of Subsidiary Borrowers’ other obligations under the
Loan Documents, such Funding Borrower shall be entitled to contribution from each benefited
Subsidiary Borrower for the amount of the Contribution so benefited (any such contribution, a
“Reimbursement Contribution”), up to such benefited Subsidiary Borrower’s then current
Allocable Principal Balance. Any Reimbursement Contributions required to be made hereunder shall,
subject to §36, be made within ten (10) days after demand therefor.

          (c) If a Subsidiary Borrower (a “Defaulting Borrower”) shall have failed to make a
Reimbursement Contribution as hereinabove provided, after the later to occur of (a) payment of the
Loan in full and the satisfaction of all of all Subsidiary Borrowers’ other obligations to Lenders
or (b) the date which is 366 days after the payment in full of the Loans, the Funding Borrower to
whom such Reimbursement Contribution is owed shall be subrogated

115

 

to the rights of Lenders against such Defaulting Borrower, including the right to receive a
portion of such Defaulting Borrower’s Collateral in an amount equal to the Reimbursement
Contribution payment required hereunder that such Defaulting Borrower failed to make;
provided, however, if Agent returns any payments in connection with a bankruptcy of
a Subsidiary Borrower, all other Subsidiary Borrowers shall jointly and severally pay to Agent and
Lenders all such amounts returned, together with interest at the Default Rate accruing from and
after the date on which such amounts were returned.

          (d) In the event that at any time there exists more than one Funding Borrower with respect to
any Contribution (in any such case, the “Applicable Contribution”), then Reimbursement
Contributions from Defaulting Borrowers pursuant hereto shall be equitably allocated among such
Funding Borrowers. In the event that at any time any Subsidiary Borrower pays an amount hereunder
in excess of the amount calculated pursuant to this paragraph, that Subsidiary Borrower shall be
deemed to be a Funding Borrower to the extent of such excess and shall be entitled to a
Reimbursement Contribution from the other Borrowers in accordance with the provisions of this §37.

          (e) It is the intent of each Subsidiary Borrower, the Agent and the Lenders that in any
proceeding under the Bankruptcy Code or any similar debtor relief laws, such Subsidiary Borrower’s
maximum obligation hereunder shall equal, but not exceed, the maximum amount which would not
otherwise cause the obligations of such Subsidiary Borrower hereunder (or any other obligations of
such Subsidiary Borrower to the Agent and the Lenders under the Loan Documents) to be avoidable or
unenforceable against such Subsidiary Borrower in such proceeding as a result of applicable Laws,
including, without limitation, (i) Section 548 of the Bankruptcy Code and (ii) any state fraudulent
transfer or fraudulent conveyance act or statute applied in such proceeding, whether by virtue of
Section 544 of the Bankruptcy Code or otherwise. The Laws under which the possible avoidance or
unenforceability of the obligations of such Subsidiary Borrower hereunder (or any other obligations
of such Subsidiary Borrower to the Agent and the Lenders under the Loan Documents) shall be
determined in any such proceeding are referred to herein as “Avoidance Provisions”. Accordingly, to
the extent that the obligations of a Subsidiary Borrower hereunder would otherwise be subject to
avoidance under the Avoidance Provisions, the maximum Obligations for which such Subsidiary
Borrower shall be liable hereunder shall be reduced to the greater of (A) the amount which, as of
the time any of the Obligations are deemed to have been incurred by such Subsidiary Borrower under
the Avoidance Provisions, would not cause the obligations of such Subsidiary Borrower hereunder (or
any other obligations of such Subsidiary Borrower to the Agent and the Lenders under the Loan
Documents), to be subject to avoidance under the Avoidance Provisions or (B) the amount which, as
of the time demand is made hereunder upon such Subsidiary Borrower for payment on account of the
Obligations, would not cause the obligations of such Subsidiary Borrower hereunder (or any other
obligations of such Subsidiary Borrower to the Agent and the Lenders under the Loan Documents), to
be subject to avoidance under the Avoidance Provisions. The provisions of this §37(e) are intended
solely to preserve the rights of the Agent and the Lenders hereunder to the maximum extent that
would not cause the obligations of any Subsidiary Borrower hereunder to be subject to avoidance
under the Avoidance Provisions, and no Subsidiary Borrower or any other Person shall have any right
or claim under this Section as against the Agent and the Lenders that would not otherwise be
available to such Person under the Avoidance Provisions.

     FOR VALUE RECEIVED, the undersigned (collectively, “Maker”), hereby promise to pay to
                                         (“Payee”), or order, in accordance with the terms of that
certain Credit Agreement, dated as of September 28, 2010, as from time to time in effect, among
CoreSite, L.P., the Subsidiary Borrowers, KeyBank National Association, for itself and as Agent,
and such other Lenders as may be from time to time named therein (the “Credit Agreement”), to the
extent not sooner paid, on or before the Revolving Credit Maturity Date, the principal sum of
                     ($                    ), or such amount as may be advanced by the Payee under the Credit
Agreement as a Revolving Credit Loan with daily interest from the date thereof, computed as
provided in the Credit Agreement, on the principal amount hereof from time to time unpaid, at a
rate per annum on each portion of the principal amount which shall at all times be equal to the
rate of interest applicable to such portion in accordance with the Credit Agreement, and with
interest on overdue principal and, to the extent permitted by applicable law, on overdue
installments of interest and late charges at the rates provided in the Credit Agreement. Interest
shall be payable on the dates specified in the Credit Agreement, except that all accrued interest
shall be paid at the stated or accelerated maturity hereof or upon the prepayment in full hereof.
Capitalized terms used herein and not otherwise defined herein shall have the meanings set forth in
the Credit Agreement.

     Payments hereunder shall be made to the Agent for the Payee at 127 Public Square, Cleveland,
Ohio 44114-1306, or at such other address as Agent may designate from time to time, or made by wire
transfer in accordance with wiring instructions provided by the Agent.

     This Note is one of one or more Revolving Credit Notes evidencing borrowings under and is
entitled to the benefits and subject to the provisions of the Credit Agreement. The principal of
this Note may be due and payable in whole or in part prior to the Revolving Credit Maturity Date
and is subject to mandatory prepayment in the amounts and under the circumstances set forth in the
Credit Agreement, and may be prepaid in whole or from time to time in part, all as set forth in the
Credit Agreement.

     Notwithstanding anything in this Note to the contrary, all agreements between the undersigned
Maker and the Lenders and the Agent, whether now existing or hereafter arising and whether written
or oral, are hereby limited so that in no contingency, whether by reason of acceleration of the
maturity of any of the Obligations or otherwise, shall the interest contracted for, charged or
received by the Lenders exceed the maximum amount permissible under applicable law. If, from any
circumstance whatsoever, interest would otherwise be payable to the Lenders in excess of the
maximum lawful amount, the interest payable to the Lenders shall be reduced to the maximum amount
permitted under applicable law; and if from any circumstance the Lenders shall ever receive
anything of value deemed interest by applicable law in excess of the maximum lawful amount, an
amount equal to any excessive interest shall be applied to the reduction of the principal balance
of the Obligations of the undersigned Maker and to the payment of interest or, if such excessive
interest exceeds the unpaid balance of principal of

A-1

 

the Obligations of the undersigned Maker, such excess shall be refunded to the undersigned
Maker. All interest paid or agreed to be paid to the Lenders shall, to the extent permitted by
applicable law, be amortized, prorated, allocated and spread throughout the full period until
payment in full of the principal of the Obligations of the undersigned Maker (including the period
of any renewal or extension thereof) so that the interest thereon for such full period shall not
exceed the maximum amount permitted by applicable law. This paragraph shall control all agreements
between the undersigned Maker and the Lenders and the Agent.

     In case an Event of Default shall occur, the entire principal amount of this Note may become
or be declared due and payable in the manner and with the effect provided in said Credit Agreement.

     This Note shall be governed by the laws of the State of New York, including, without
limitation, New York General Obligations Law Section 5-1401.

     The undersigned Maker and all guarantors and endorsers, to the extent permitted by applicable
law, hereby waive presentment, demand, notice, protest, notice of intention to accelerate the
indebtedness evidenced hereby, notice of acceleration of the indebtedness evidenced hereby and all
other demands and notices in connection with the delivery, acceptance, performance and enforcement
of this Note, except as specifically otherwise provided in the Credit Agreement, and assent to
extensions of time of payment or forbearance or other indulgence without notice.

     FOR VALUE RECEIVED, the undersigned (collectively, “Maker”), hereby promise to pay to

Exhibit 10.6

CORESITE REALTY CORPORATION

RESTRICTED STOCK AGREEMENT

     This Restricted Stock Agreement (the “Agreement”) is entered into effective as of
___________, 2010 (the “Effective Date”), by and between CoreSite Realty Corporation, a
Maryland corporation (the “Company”), and __________________ (“Holder”).

     WHEREAS, on December 22, 2009, Holder was granted a Class B Interest (as defined in the LLC
Agreement (as defined below)) in CRP Master Holdings, LLC (“Master Holdco”), the details of
which are set forth on Exhibit A (the “Interest”);

     WHEREAS, the Interest was governed by that certain Amended and Restated Limited Liability
Company Agreement of Master Holdco, as amended from time to time (the “LLC Agreement”);

     WHEREAS, the LLC Agreement provides that in connection with an initial public offering of the
equity securities of Master Holdco or one of its successors or affiliates, the Manager (as defined
in the LLC Agreement) may require the Holder to exchange his or her Interest for another class of
equity securities of Master Holdco, its successor or their affiliates;

     WHEREAS, the Company is the sole general partner of CoreSite L.P., a Delaware partnership (the
“Partnership”) and will operate as a self-administered and self-managed real estate
investment trust within the meaning of Section 856 of the Internal Revenue Code of 1986, as amended
(a “REIT”);

     WHEREAS, in connection with the initial public offering of shares of common stock of the
Company, which entity, together with the Partnership, is the successor to Master Holdco, the
Manager and the board of directors of the Company (the “Board”) have each determined that
the Holder shall exchange his or her Interest for a number of shares of common stock of the Company
(the “Common Stock”) as set forth on Exhibit A (such shares of Common Stock are referred to
as the “Restricted Shares”), subject to the terms and conditions of, this Agreement (the
“Exchange”);

     WHEREAS, the Board has approved this Agreement which will govern the Restricted Shares; and

     WHEREAS, the Company and Holder wish to enter into this Agreement which will govern and set
forth the terms of the Restricted Shares.

     NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and
valuable consideration, including the conversion and exchange of the Interest, the receipt and
sufficiency of which are hereby acknowledged, the Company and Holder hereby agree as follows:

ARTICLE I.

GENERAL

     1.1 Restricted Shares. Holder is the holder of such number of Restricted Shares as is
set forth on Exhibit A. The Restricted Shares shall be subject to the terms and conditions of this
Agreement.

     1.2 Exchange. Holder acknowledges that the Restricted Shares have been issued to
Holder in exchange for all of Holder’s rights with respect to the Interest and that as of the
Effective Date, he or she no longer has any rights with respect to the Interest. The Holder hereby
agrees and consents to the Exchange
and understands and acknowledges that the Restricted Shares are being issued in full
settlement of all of the Holder’s rights under the LLC Agreement or under any other documents or
agreements related to or in

 

 

connection with the Interest or any other interest in Master Holdco or
any of its affiliates, predecessors or successors. The Holder agrees that he or she shall execute
such additional documents and take such actions as may be requested by the Company in order to
effect the Exchange.

     1.3 Ownership, Rights as a Shareholder and Custody. Holder is the owner of the Restricted
Shares and has all the rights of a shareholder with respect thereto, including the right to vote
such Restricted Shares and to receive all dividends or other distributions paid with respect to
such Restricted Shares. Such ownership of Restricted Shares shall be evidenced by book entries on the records of the
Company. Unless provided otherwise pursuant to another agreement between the Holder and the
Company or its successor, promptly following the vesting of Restricted Shares pursuant to this
Agreement, shares evidencing such Restricted Shares shall be transferred into Holder’s brokerage account or participant trust maintained
with the Company’s agent or, in the Company’s sole discretion, stock certificate(s) shall be issued
and delivered to Holder (or his/her permitted transferees) by the Company with such legends as
shall be determined by the Company.

ARTICLE II.

FORFEITURE, VESTING, NON-TRANSFERABILITY

     2.1 Forfeiture. Unless otherwise determined by the Committee, or as otherwise set
forth in a written agreement between the Holder and the Company, the Partnership or any of their
subsidiaries, any Restricted Shares which have not vested as of the date Holder incurs a
Termination of Employment (as defined below) shall automatically be forfeited by Holder on the date
of such Termination of Employment without any additional consideration therefore and without any
further action by the Company. The Committee in its discretion may accelerate the vesting of any
Restricted Shares.

     2.2 Vesting of Restricted Shares.

          (a) The number of Restricted Shares that are designated as vested on Exhibit A shall be fully
vested and non-forfeitable as of the Effective Date.

          (b) The number of Restricted Shares that are designated as unvested on Exhibit A shall vest,
if at all, as indicated on Exhibit A, subject to the Holder’s continued employment with or service
to the Company, the Partnership or any of their subsidiaries.

     2.3 Nontransferability. No unvested Restricted Shares or any interest or right
therein or part thereof shall be subject to disposition by transfer, alienation, anticipation,
pledge, encumbrance, assignment or any other means whether such disposition be voluntary or
involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or
equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null
and void and of no effect

     2.4 Adjustment Upon Changes in Capitalization, Merger or Asset Sale.

     (a) Changes in Capitalization. Subject to any required action by the shareholders of
the Company, the number of Restricted Shares subject to this Agreement, shall be equitably
adjusted, as determined by the Committee, for any change in the number of issued shares of Common
Stock resulting

2

 

from a stock split, reverse stock split, stock dividend, spin-off, combination or
reclassification of the Common Stock, or any other change in the number of issued shares of Common
Stock effected without receipt of consideration by the Company; provided, however, that a
conversion of any convertible securities of the Company, the issuance of Restricted Shares to any
other employee of the Company or its subsidiaries, or the exchange by the Company of any Common
Units of the Partnership (as defined in the Partnership Agreement) for shares of Common Stock shall
not be deemed to have been “effected without receipt of consideration.” Such adjustment, if any,
shall be made by the Committee, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of
any class, or securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number of Restricted Shares subject
to this Agreement.

          (b) Merger or Asset Sale. In the event of a merger of the Company with or into another
corporation, or the sale of substantially all of the assets of the Company, the Agreement shall be
assumed by the successor corporation or a parent or subsidiary of the successor corporation. In
the event that the successor corporation or a parent or subsidiary of the successor corporation
refuses to assume the Agreement, the Restricted Shares shall vest and the transfer restrictions set
forth in this Agreement shall immediately lapse.

ARTICLE III.

OTHER PROVISIONS

     3.1 Definitions. For purposes of this Agreement, the terms set forth below shall have
the following meanings:

          (a) “Committee” means the Board of Directors of the Company or a committee appointed
by the Board to administer this Agreement.

          (b) “Termination of Employment” means the time when the engagement of Holder as an
employee of or service provider to the Company, the Partnership or any of their subsidiaries is
terminated for any reason, with or without cause, including, but not by way of limitation, by
resignation, discharge, death or retirement, but excluding (x) terminations where there is
simultaneous commencement by the former Holder of a relationship with the Company, the Partnership
or one of their subsidiaries as an employee and (y) at the discretion of the Committee,
terminations which result in a temporary severance of the service relationship.

     3.2 Taxes.

          (a) Holder represents to the Company and the Partnership that the Holder has reviewed with his
or her own tax advisors the federal, state, local and foreign tax consequences of this investment
and the transactions contemplated by this Agreement. Holder is relying solely on such advisors and
not on any statements or representations of the Company or any of its agents. Holder understands
that Holder (and not the Company) shall be responsible for his or her own tax liability that may
arise as a result of this investment or the transactions contemplated by this Agreement.

          (b) Holder understands that Holder may be taxed on the Exchange with respect to all of the
Restricted Shares, both vested and unvested. Holder shall be solely responsible for any tax
consequences associated with the Restricted Shares. In the event the Company or the Partnership
determines that any tax withholding shall become due in connection with the Restricted Shares, the
Holder shall make appropriate arrangements for the payment to the Company (or its subsidiary, as
applicable) of all amounts, if any, which the Company (or its subsidiary, as applicable) is
required to withhold under

3

 

applicable law with respect to the Restricted Shares. The Company may
refuse to issue any Restricted Shares to Holder until Holder satisfies the tax withholding
obligations. To the maximum extent permitted by law, the Company (or its subsidiary, as applicable)
has the right to retain without notice from Restricted Shares transferable to Holder upon vesting
or from compensation payable to Holder, shares of Common Stock or cash having a value sufficient to
satisfy the tax withholding obligation in the event the tax withholding obligation is not satisfied
by the Holder.

     3.3 Not a Contract of Employment. Nothing in this Agreement shall confer upon Holder
any right to continue to serve as an employee or other service provider of the Company, the
Partnership or any of their subsidiaries.

     3.4 Governing Law. The laws of the State of Delaware shall govern the
interpretation, validity, administration, enforcement and performance of the terms of this
Agreement regardless of the law that might be applied under principles of conflicts of laws.

     3.5 Administration of the Agreement. The Committee shall have the authority, in its
discretion, to construe and interpret the terms of this Agreement, to prescribe, amend and rescind
rules and regulations relating to the Agreement and to make all other determinations deemed
necessary or advisable for administering the Agreement. The Committee’s decisions and
interpretations shall be final and binding on Holder and all other persons.

     3.6 Amendment, Suspension and Termination. This Agreement may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time to time by the
Committee, provided, that, except as may otherwise be provided, directly or indirectly, in this
Agreement, no amendment, modification, suspension or termination of this Agreement shall adversely
effect the Restricted Shares without the prior written consent of Holder.

     3.7 Notices. Notices required or permitted hereunder shall be given in writing and
shall be deemed effectively given upon personal delivery or upon deposit in the United States mail
by certified mail, with postage and fees prepaid, addressed to Holder at his or her address shown
in the Company records, and to the Company at its principal executive office.

     3.8 Successors and Assigns. The Company may assign any of its rights under this
Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the
successors and assigns of the Company. Subject to the restrictions on transfer herein set forth,
this Agreement shall be binding upon Holder and his or her heirs, executors, administrators,
successors and assigns.

     3.9 Entire Agreement. This Agreement and the exhibits constitute the entire agreement
among the parties hereto pertaining to the subject matter of this Agreement and supersede all prior
agreements and understandings pertaining thereto, including the LLC Agreement. No oral
understandings, oral statements, oral promises or oral inducements between the parties hereto
relating to this Agreement exist. No representations, warranties, covenants or conditions, express
or implied, whether by statute or otherwise, other than as set forth in this Agreement, have been
made by the parties hereto. The parties hereto agree
that, effective as of the Effective Date, the Holder shall no longer have any rights or
obligations under the LLC Agreement

     3.10 Third Party Beneficiaries. This Agreement shall inure to the benefit of the
parties hereto and, with respect to Section 1.2 and 3.9, to Master Holdco and its affiliates,
successors and predecessors, and their officers, directors and equity holders (each of whom shall
be deemed to be intended third party beneficiaries hereunder).

4

 

     3.11 Execution. This Agreement may be executed in two or more counterparts, or by
facsimile transmission, each of which shall be deemed to be an original and all of which taken
together shall constitute one and the same instrument.

     3.12 REIT Status. This Agreement shall be interpreted and construed in a manner
consistent with the Company’s status as a REIT. Notwithstanding anything in this Agreement to the
contrary, no Restricted Shares shall become vested:

          (a) to the extent such Restricted Shares could cause Holder to be in violation of the
Ownership Limit (as defined in the Company’s Articles of Incorporation, as amended from time to
time); or

          (b) if, in the discretion of the Committee, the vesting of such Restricted Shares could impair
the Company’s status as a REIT.

     3.13 Clawback. To the extent required by applicable law or any applicable securities
exchange listing standards, the Restricted Shares and any proceeds thereof shall be subject to
clawback as determined by the Committee, which clawback may include forfeiture, repurchase and/or
recoupment of the Restricted Shares and amounts paid or payable pursuant to or with respect to the
Restricted Shares.
