computed on the basis of a year of 360 days, and in each case shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). The applicable Base
Rate shall be determined by the Agent, and such determination shall be conclusive absent manifest
error.

          (d) Repayment of Revolving Loans. The Borrower unconditionally promises to pay to the
Agent for the account of each Revolving Credit Lender the then unpaid principal amount of such
Lender’s Revolving Loans on the Revolving Credit Maturity Date. In addition, if following any
reduction in the Revolving Credit Commitments or at any other time the Revolving Credit Exposure
shall exceed the Revolving Credit Commitment at such time, the Borrower shall first, repay Swing
Loans, second, repay Revolving Loans, and third, to the extent necessary, provide cash collateral
for Total LC Exposure as specified in Section 2.4(h), in an aggregate amount equal to such excess.
In addition, at all times when the AutoBorrow Agreement is in effect, the Borrower shall repay
outstanding Revolving Loans in accordance with the terms of the AutoBorrow Agreement.

          (e) Loan Accounts. Each Revolving Credit Lender shall maintain in accordance with its
usual practice an account evidencing the indebtedness of the Borrower to such Lender resulting from
each Revolving Loan made by such Lender, including the amounts of principal and interest payable
and paid to such Lender from time to time hereunder. The Agent shall maintain accounts in which it
shall record the amount of each Revolving Loan made hereunder, the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each Revolving Credit
Lender hereunder and the amount of any sum received by the Agent hereunder for the account of the
Revolving Credit Lenders and each Revolving Credit Lender’s share thereof. The entries made in the
account maintained by the Agent pursuant to this subsection 2.1(e) shall absent manifest error be
prima facie evidence of the existence and amounts of the obligations recorded therein;
provided that the failure of the Agent to maintain such account or any error therein shall
not in any manner affect the obligation of the Borrower to repay the Revolving Loans in accordance
with the terms of this Agreement.

          (f) Revolving Credit Notes. Prior to the Restatement Date, the Borrower shall
prepare, execute and deliver to each Revolving Credit Lender a Revolving Credit Note in the
principal amount of such Lender’s Revolving Credit Commitment. Thereafter, the Revolving Loans of
each Revolving Credit Lender evidenced by such Revolving Credit Note and interest thereon shall at
all times (including after assignment pursuant to Section 11.4) be represented by one or more
promissory notes in such form payable to the order of the payee named therein.

     2.2 [Reserved.]

     2.3 LIBOR Borrowings.

          (a) General. Each Revolving Loan initially shall be a Base Rate Loan. Thereafter,
the Borrower may elect to convert any portion of the outstanding Revolving Loans to a LIBOR
Borrowing. The Borrower may elect different options for continuations and conversions with respect
to different portions of the affected Borrowing, except with respect to Swing Loans, in which case
the Loans comprising each such portion shall be considered a separate Borrowing. The Borrower
shall not be permitted to select any Interest Period for any LIBOR Borrowing that ends after the
Revolving Credit Maturity Date.

          (b) Interest on LIBOR Borrowings. Each LIBOR Borrowing shall bear interest during the
applicable Interest Period at a rate per annum equal to the Eurodollar Rate plus the Applicable
Margin. Notwithstanding the foregoing, (i) all LIBOR Borrowings which are not paid when due shall
automatically be converted into Base Rate Borrowings and shall bear interest until paid in full at
the Post-Default Rate, (ii) during the period when any Event of Default of the type described in
clauses (g), (h) or

- 24 -

 

(i) of Section 9.1 shall have occurred and be continuing, all LIBOR Borrowings shall
automatically be converted into Base Rate Borrowings and shall bear interest, after as well as
before judgment, at the Post-Default Rate, (iii) if there shall occur and be continuing any Event
of Default (other than an Event of Default of the type described in clauses (g), (h) or (i) of
Section 9.1), following written notice delivered to the Borrower from the Agent at the request of
the Required Lenders, all LIBOR Borrowings shall automatically be converted into Base Rate
Borrowings and shall bear interest, after as well as before judgment, at the Post-Default Rate
during the period beginning on the date such Event of Default first occurred, and ending on the
date such Event of Default is cured or waived. Accrued interest on each LIBOR Borrowing shall be
payable in arrears on the last Business Day of the Interest Period applicable to such LIBOR
Borrowing; provided that (a) in the case of a LIBOR Borrowing with a Interest Period of
more than three months’ duration, accrued interest shall be due on the last Business Day of such
Interest Period and on the last Business Day of each three month period, and (b) interest accrued
at the Post-Default Rate shall be payable on demand. All interest hereunder shall be computed on
the basis of a year of 360 days, and in each case shall be payable for the actual number of days
elapsed (including the first day but excluding the last day). The applicable Eurodollar Rate or
Eurodollar Base Rate shall be determined by the Agent, and such determination shall be conclusive
absent manifest error.

          (c) Procedure for Requesting LIBOR Borrowings. To request that any portion of the
outstanding Revolving Loans be converted into a LIBOR Borrowing, or, to request that any LIBOR
Borrowing continue as a LIBOR Borrowing for an additional Interest Period, the Borrower shall
notify the Agent of such request by telephone (i) in the case of a LIBOR Borrowing, not later than
1:00 p.m., Boston, Massachusetts time, three Business Days before the date of the proposed
conversion or continuation of such Borrowing. Each such Interest Election Request made by the
Borrower shall be irrevocable and shall be confirmed promptly by hand delivery, telecopy or
electronic transmission to the Agent of a written Advance Request in the form of Exhibit B
hereto, setting forth all of the information required to be set forth therein, and signed by a
Designated Financial Officer of the Borrower. No Swing Loan shall be converted from a Base Rate
Borrowing to a LIBOR Borrowing. Promptly following receipt of an Interest Election Request, the
Agent shall advise each affected Lender of the details thereof and of such Lender’s portion of each
resulting Borrowing. Subject to the provisions of subsection 2.3(f) and provided that no Default
or Event of Default shall have occurred and be continuing and the Agent, at the request of the
Required Lenders shall have so notified the Borrower, upon receipt of an Interest Election Request,
the Lenders shall on the requested date of conversion or continuation (i) convert the Base Rate
Loan requested to be converted into a LIBOR Loan for the Interest Period set forth in such Interest
Election Request and/or (ii) continue the LIBOR Loan requested to be continued as a LIBOR Loan for
the additional Interest Period set forth in such Interest Election Request. Each Lender at its
option may make any LIBOR Loan by causing any domestic or foreign branch of any Affiliate of such
Lender to make such Loan; provided that any exercise of such option shall not affect the obligation
of the Borrower to repay such Loan in accordance with the terms of this Agreement.

          (d) Incomplete Interest Election Requests. If any Interest Election Request is
incomplete in any respect, then such Interest Election Request shall be void and the Borrowing
which was the subject matter of such Interest Election Request shall continue as a Base Rate
Borrowing. If, with respect to any existing LIBOR Borrowing, the Borrower fails to deliver an
Interest Election Request to continue such LIBOR Borrowing at least three Business Days prior to
the expiration of the Interest Period for such existing LIBOR Borrowing, such LIBOR Borrowing shall
automatically convert to a Base Rate Borrowing at the expiration of such Interest Period.

          (e) Limit on LIBOR Borrowings. At the commencement of each Interest Period for a
LIBOR Borrowing, such Borrowing shall be in an aggregate amount at least equal to $500,000 or any
greater multiple of $100,000. Borrowings of more than one Type may be outstanding at the same
time; provided that there shall not at any time be more than a total of seven (7) LIBOR
Borrowings outstanding.

- 25 -

 

          (f) Alternate Rate of Interest. If prior to the commencement of any Interest Period
for a LIBOR Borrowing, (i) the Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the Eurodollar
Rate or the Eurodollar Base Rate for such Interest Period, (ii) the Agent is advised by the
Required Revolving Credit Lenders that the Eurodollar Rate or the Eurodollar Base Rate for such
Interest Period will not adequately and fairly reflect the cost to such Lenders of making or
maintaining their Loans included in such LIBOR Borrowing, or (iii) if the Agent or any Lender shall
have determined in good faith that as a result of any Change in Law it is unlawful or impossible
for any Lender to make or maintain any LIBOR Borrowing; then in each case the Agent shall give
notice thereof to the Borrower and the affected Lenders by telephone or telecopy as promptly as
practicable thereafter and, until the Agent notifies the Borrower and such Lenders that the
circumstances giving rise to such notice no longer exist, any Interest Election Request submitted
by the Borrower shall be ineffective; provided that if as a result of a Change in Law the
Lenders are prohibited from maintaining any outstanding LIBOR Borrowing, upon notice from the
Agent, the Borrower shall immediately (A) convert such LIBOR Borrowing to a Base Rate Loan, or (B)
repay such LIBOR Borrowing in full, together with all interest accrued thereon and all fees and
other amounts payable to the Lenders hereunder (in either case, subject to the provisions of
subsection 2.3(g) of this Agreement with respect to redeployment costs).

          (g) Break Funding Payments. In the event of (i) the payment of any principal of any
LIBOR Loan other than on the last day of the Interest Period applicable thereto (including as a
result of an Event of Default), (ii) the conversion of any LIBOR Loan other than on the last day of
the Interest Period applicable thereto, or (iii) the failure to borrow, convert, continue or prepay
any LIBOR Loan on the date specified in any notice delivered pursuant hereto (regardless of whether
such notice is permitted to be revocable and is revoked in accordance herewith), then, in any such
event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to
such event, as determined by such Lender in a manner consistent with its customs and practices. In
the event that any Lender is entitled to receive compensation pursuant to this subsection 2.3(g),
such Lender shall deliver a certificate to the Borrower setting forth the amount or amounts that
such Lender is entitled to receive, and the Borrower shall pay such Lender such amount or amounts
within three (3) days after receipt of such certificate.

     2.4 Letters of Credit.

          (a) General. Subject to the terms and conditions set forth herein, in addition to the
Revolving Loans provided for in Section 2.1 and the Swing Loans provided for in Section 2.6(a), the
Borrower may request the issuance of Letters of Credit for its own account by the Issuing Lender,
in a form reasonably acceptable to the Issuing Lender, at any time and from time to time during the
Revolving Credit Availability Period. Letters of Credit issued hereunder shall constitute
utilization of the Revolving Credit Commitments and, without limitation of the provisions of
Section 2.1 (a), in no event shall the Total LC Exposure at any time exceed $10,000,000. In the
event of any inconsistency between the terms and conditions of this Agreement and the terms and
conditions of any form of letter of credit application or other agreement submitted by the Borrower
to, or entered into by the Borrower with, the Issuing Lender relating to any Letter of Credit, the
terms and conditions of this Agreement shall control. Each of the letters of credit identified on
Schedule 2.4 (collectively, the “Existing Letters of Credit”) shall be deemed to
have been issued pursuant hereto, and from and after the Restatement Date shall be subject to and
governed by the terms and conditions hereof so long as they remain outstanding.

          (b) Procedures for Issuance, Amendment and Extension of Letters of Credit.

          (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the
request of the Borrower delivered to the Issuing Lender (with a copy to the Agent) in the
form of an LC Application, appropriately completed and signed by a Designated Financial

- 26 -

 

Officer of the Borrower. Such LC Application must be received by the Issuing Lender
and the Agent not later than 11:00 a.m. Boston, Massachusetts time at least two Business
Days (or such later date and time as the Agent and the Issuing Lender may agree in a
particular instance in their sole discretion) prior to the proposed issuance date or date of
amendment, as the case may be. In the case of a request for an initial issuance of a Letter
of Credit, such LC Application shall specify in form and detail satisfactory to the Issuing
Lender: (A) the proposed issuance date of the requested Letter of Credit (which shall be a
Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address
of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of
any drawing thereunder; (F) the full text of any certificate to be presented by such
beneficiary in case of any drawing thereunder; (G) the purpose and nature of the requested
Letter of Credit; and (H) such other matters as the Issuing Lender may reasonably require.
In the case of a request for an amendment of any outstanding Letter of Credit, such LC
Application shall specify in form and detail reasonably satisfactory to the Issuing Lender
(A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which
shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other
matters as the Issuing Lender may reasonably require. Additionally, the Borrower shall
furnish to the Issuing Lender and the Agent such other documents and information pertaining
to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as
the Issuing Lender or the Agent may require.

          (ii) Promptly after receipt of any LC Application, the Issuing Lender will confirm with
the Agent (by telephone or in writing) that the Agent has received a copy of such LC
Application from the Borrower and, if not, the Issuing Lender will provide the Agent with a
copy thereof. Unless the Issuing Lender has received written notice from any Lender, the
Agent or any Loan Party, at least one Business Day prior to the requested date of issuance
or amendment of the applicable Letter of Credit, that one or more applicable conditions in
Article 6 shall not then be satisfied, then, subject to the terms and conditions hereof, the
Issuing Lender shall, on the requested date, issue a Letter of Credit for the account of the
Borrower or enter into the applicable amendment, as the case may be, in each case in
accordance with the Issuing Lender’s usual and customary business practices. Immediately
upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the Issuing Lender a risk
participation in such Letter of Credit in an amount equal to the product of such Lender’s
Applicable Percentage multiplied by the amount of such Letter of Credit.

          (iii) Promptly after its delivery of any Letter of Credit or any amendment to a Letter
of Credit to an advising bank with respect thereto or to the beneficiary thereof, the
Issuing Lender will also deliver to the Borrower and the Agent a true and complete copy of
such Letter of Credit or amendment.

          (iv) If the Borrower so requests in any applicable LC Application, the Issuing Lender
may, in its sole and absolute discretion, agree to issue a Letter of Credit that has
automatic extension provisions (each, an “Auto-Extension Letter of Credit”);
provided that any such Auto-Extension Letter of Credit must permit the Issuing
Lender to prevent any such extension at least once in each twelve-month period (commencing
with the date of issuance of such Letter of Credit) by giving prior notice to the
beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each
such twelve-month period to be agreed upon at the time such Letter of Credit is issued.
Unless otherwise directed by the Issuing Lender, the Borrower shall not be required to make
a specific request to the Issuing Lender for any such extension. Once an Auto-Extension
Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may
not require) the Issuing Lender to permit the extension of such Letter of Credit at any time
to

- 27 -

 

an expiry date not later than the L/C Expiration Date; provided, however, that
the Issuing Lender shall not permit any such extension if (A) the Issuing Lender has
determined that it would not be permitted, or would have no obligation, at such time to
issue such Letter of Credit in its revised form (as extended) under the terms hereof (by
reason of the provisions of clause (ii) or (iii) of Section 2.03(a) or otherwise), or (B) it
has received notice (which may be by telephone or in writing) on or before the day that is
five Business Days before the Non-Extension Notice Date (1) from the Agent that the Required
Lenders have elected not to permit such extension or (2) from the Agent, any Lender or the
Borrower that one or more of the applicable conditions specified in Section 4.02 is not then
satisfied, and in each such case directing the Issuing Lender not to permit such extension.

          (c) Drawings and Reimbursements; Funding of Participations.

          (i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a
drawing under such Letter of Credit, the Issuing Lender shall notify the Borrower and the
Agent thereof. Not later than 11:00 a.m. Boston, Massachusetts time on the date of any
payment by the Issuing Lender under a Letter of Credit (each such date, an “Honor
Date”), the Borrower shall reimburse the Issuing Lender through the Agent in an amount
equal to the amount of such drawing (each such obligation of the Borrower, a
“Reimbursement Obligation”). If the Borrower fails to pay any Reimbursement
Obligation to the Issuing Lender by such time, the Agent shall promptly notify each Lender
of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed
Amount”), and the amount of such Lender’s Applicable Percentage thereof. In such event,
the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans to be
disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, but subject to
the amount of the unutilized portion of the Commitments and the conditions set forth in
Section 6.2 (other than the delivery of an Advance Request). Any notice given by the
Issuing Lender or the Agent pursuant to this Section 2.4(c)(i) may be given by telephone if
immediately confirmed in writing; provided that the lack of such an immediate
confirmation shall not affect the conclusiveness or binding effect of such notice.

          (ii) Each Lender shall upon any notice pursuant to Section 2.4(c)(i) make funds
available to the Agent for the account of the Issuing Lender in an amount equal to its
Applicable Percentage of the Unreimbursed Amount not later than 1:00 p.m. Boston,
Massachusetts time on the Business Day specified in such notice by the Agent, whereupon,
subject to the provisions of Section 2.4(c)(iii), each Lender that so makes funds available
shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The Agent
shall remit the funds so received to the Issuing Lender.

          (iii) With respect to any Unreimbursed Amount that is not fully refinanced by a
Borrowing of Base Rate Loans because the conditions set forth in Section 6.2 cannot be
satisfied or for any other reason, the Borrower shall be deemed to have incurred from the
Issuing Lender an LC Disbursement in the amount of the Unreimbursed Amount that is not so
refinanced, which LC Disbursement shall be due and payable on demand (together with
interest) and shall bear interest at the Default Rate. In such event, each Lender’s payment
to the Agent for the account of the Issuing Lender pursuant to Section 2.4(c)(ii) shall be
deemed payment in respect of its participation in such LC Disbursement and shall constitute
an LC Advance from such Lender in satisfaction of its participation obligation under this
Section 2.4.

          (iv) Until each Lender funds its Base Rate Loan or LC Advance pursuant to this Section
2.4(c) to reimburse the Issuing Lender for any amount drawn under any Letter of

- 28 -

 

Credit, interest in respect of such Lender’s Applicable Percentage of such amount shall
be solely for the account of the Issuing Lender.

          (v) Each Lender’s obligation to make Base Rate Loans or LC Advances to reimburse the
Issuing Lender for amounts drawn under Letters of Credit, as contemplated by this Section
2.4(c), shall be absolute and unconditional and shall not be affected by any circumstance,
including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender
may have against the Issuing Lender, the Borrower or any other Person for any reason
whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence,
event or condition, whether or not similar to any of the foregoing; provided, however, that
each Lender’s obligation to make Committed Loans pursuant to this Section 2.4(c) is subject
to the conditions set forth in Section 6,2 (other than delivery by the Borrower of an
Advance Request). No such making of an LC Advance shall relieve or otherwise impair the
obligation of the Borrower to reimburse the Issuing Lender for the amount of any payment
made by the Issuing Lender under any Letter of Credit, together with interest as provided
herein.

          (vi) If any Lender fails to make available to the Agent for the account of the Issuing
Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of
this Section 2.4(c) by the time specified in Section 2.4(c)(ii), the Issuing Lender shall be
entitled to recover from such Lender (acting through the Agent), on demand, such amount with
interest thereon for the period from the date such payment is required to the date on which
such payment is immediately available to the Issuing Lender at a rate per annum equal to the
greater of the Federal Funds Effective Rate and a rate determined by the Issuing Lender in
accordance with banking industry rules on interbank compensation, plus any administrative,
processing or similar fees customarily charged by the Issuing Lender in connection with the
foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the
amount so paid shall constitute such Lender’s Loan included in the relevant Borrowing or LC
Advance in respect of the relevant LC Disbursement, as the case may be. A certificate of
the Issuing Lender submitted to any Lender (through the Agent) with respect to any amounts
owing under this clause (vi) shall be conclusive absent manifest error.

          (d) Repayment of Participations.

          (i) At any time after the Issuing Lender has made a payment under any Letter of Credit
and has received from any Lender such Lender’s LC Advance in respect of such payment in
accordance with Section 2.4(c), if the Agent receives for the account of the Issuing Lender
any payment in respect of the related Unreimbursed Amount or interest thereon (whether
directly from the Borrower or otherwise, including proceeds of cash collateral applied
thereto by the Agent), the Agent will distribute to such Lender its Applicable Percentage
thereof in the same funds as those received by the Agent.

          (ii) If any payment received by the Agent for the account of the Issuing Lender
pursuant to Section 2.4(c)(i) is required to be returned under any of the circumstances
described in Section 11.15 (including pursuant to any settlement entered into by the Issuing
Lender in its discretion), each Lender shall pay to the Agent for the account of the Issuing
Lender its Applicable Percentage thereof on demand of the Agent, plus interest thereon from
the date of such demand to the date such amount is returned by such Lender, at a rate per
annum equal to the Federal Funds Effective Rate from time to time in effect. The
obligations of the Lenders under this clause shall survive the payment in full of the
Obligations and the termination of this Agreement.

- 29 -

 

          (e) Obligations Absolute. The obligation of the Borrower to reimburse the Issuing
Lender for Reimbursement Obligations and to repay each LC Disbursement shall be absolute,
unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including the following:

          (i) any lack of validity or enforceability of such Letter of Credit, this Agreement, or
any other Loan Document;

          (ii) the existence of any claim, counterclaim, setoff, defense or other right that the
Borrower or any Subsidiary may have at any time against any beneficiary or any transferee of
such Letter of Credit (or any Person for whom any such beneficiary or any such transferee
may be acting), the Issuing Lender or any other Person, whether in connection with this
Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement
or instrument relating thereto, or any unrelated transaction;

          (iii) any draft, demand, certificate or other document presented under such Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any
statement therein being untrue or inaccurate in any respect; or any loss or delay in the
transmission or otherwise of any document required in order to make a drawing under such
Letter of Credit;

          (iv) any payment by the Issuing Lender under such Letter of Credit against presentation
of a draft or certificate that does not strictly comply with the terms of such Letter of
Credit; or any payment made by the Issuing Lender under such Letter of Credit to any Person
purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of
creditors, liquidator, receiver or other representative of or successor to any beneficiary
or any transferee of such Letter of Credit, including any arising in connection with any
proceeding under any Debtor Relief Law; or

          (v) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, including any other circumstance that might otherwise constitute a defense
available to, or a discharge of, the Borrower or any Subsidiary, except any circumstance or
happening caused by the gross negligence or willful misconduct of the Issuing Lender.

The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that
is delivered to it in accordance with the procedures set forth herein and, in the event of any
claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will
promptly notify the Issuing Lender. The Borrower shall be deemed to have waived any such claim
against the Issuing Lender and its correspondents unless such notice is given as aforesaid.

          (f) Role of Issuing Lender. Each Lender and the Borrower agree that, in paying any
drawing under a Letter of Credit, the Issuing Lender shall not have any responsibility to obtain
any document (other than any sight draft, certificates and documents expressly required by the
Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or
the authority of the Person executing or delivering any such document. None of the Issuing Lender,
the Agent, any of their respective Related Parties nor any correspondent, participant or assignee
of the Issuing Lender shall be liable to any Lender for (i) any action taken or omitted in
connection herewith at the request or with the approval of Lenders or the Required Lenders, as
applicable; (ii) any action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document
or instrument related to any Letter of Credit or Issuer Document. The Borrower hereby assumes all
risks of the acts or omissions of any beneficiary or transferee with respect to

- 30 -

 

its use of any Letter of Credit; provided, however, that this assumption is not
intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may
have against the beneficiary or transferee at law or under any other agreement. None of the
Issuing Lender, the Agent, any of their respective Related Parties nor any correspondent,
participant or assignee of the Issuing Lender, shall be liable or responsible for any of the
matters described in clauses (i) through (v) of Section 2.4(e); provided, however, that
anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against the
Issuing Lender, and the Issuing Lender may be liable to the Borrower, to the extent, but only to
the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the
Borrower which were caused by the Issuing Lender’s willful misconduct or gross negligence or the
Issuing Lender’s willful failure to pay under any Letter of Credit after the presentation to it by
the beneficiary of a sight draft and certificate(s) strictly complying with the terms and
conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the
Issuing Lender may accept documents that appear on their face to be in order, without
responsibility for further investigation, and the Issuing Lender shall not be responsible for the
validity or sufficiency of any instrument transferring or assigning or purporting to transfer or
assign a 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.

          (g) Cash Collateral. If either (i) an Event of Default shall occur and be continuing
and the Borrower receives notice from the Agent or the Required Lenders demanding the deposit of
cash collateral pursuant to this paragraph, or (ii) the Borrower shall be required to provide cash
collateral for Total LC Exposure pursuant to subsections 2.1(d) or 2.9(b), the Borrower shall
immediately deposit with the Agent an amount in cash equal to, in the case of an Event of Default,
the Total LC Exposure as of such date plus any accrued and unpaid interest thereon and, in the case
of any cash collateral required to be provided pursuant to subsections 2.1(d) or 2.9(b), the amount
required under subsections 2.1(d) or 2.9(b), as the case may be; provided that the
obligation to deposit such cash collateral shall become effective immediately, and such deposit
shall become immediately due and payable, without demand or other notice of any kind, upon the
occurrence of any Event of Default described in clause (g) or (h) of Section 9.1. Such deposit
shall be held by the Agent as collateral in the first instance for the Total LC Exposure under this
Agreement and thereafter for the payment of any other obligations of the Credit Parties hereunder.
Cash collateral shall be maintained in blocked, non-interest bearing deposit accounts at Bank of
America.

          (h) Applicability of ISP and UCP. Unless otherwise expressly agreed by the Issuing
Lender and the Borrower when a Letter of Credit is issued (including any such agreement applicable
to an Existing Letter of Credit), (i) the rules of the ISP shall apply to each standby Letter of
Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most
recently published by the International Chamber of Commerce at the time of issuance shall apply to
each commercial Letter of Credit.

          (i) Confirmation of Existing Letters of Credit Issued Under Prior Credit Agreement.
All Existing Letters of Credit (including those issued under the Prior Credit Agreement)
outstanding on the Restatement Date shall be deemed to be Letters of Credit issued hereunder.

     2.5 Loans and Borrowings; Funding of Borrowings.

          (a) Loans and Borrowings. Each Loan shall be made as part of a Borrowing consisting
of Loans made by the Lenders ratably in accordance with their respective Commitments. The Failure
of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall
be responsible for any other Lender’s failure to make Loans as required herein.

- 31 -

 

          (b) Funding of Borrowings. Each Lender shall make each Loan (other than a Swing Loan)
to be made by it hereunder on the proposed date thereof by wire transfer of immediately available
funds by 2:00 p.m., Boston, Massachusetts time to the account of the Agent most recently designated
by it for such purpose by notice to the Lenders. The Agent will make such Loans (other than Swing
Loans) available to the Borrower by promptly crediting the amounts so received, in like funds, to
one or more accounts of the Borrower maintained with the Agent in Boston, Massachusetts; provided
that (i) Revolving Base Rate Loans made to finance the reimbursement of an LC Disbursement under
any Letter of Credit as provided in subsection 2.4(c) shall be remitted by the Agent to the Issuing
Lender and (ii) Revolving Credit Base Rate Loans made to finance the refunding of Swing Loans as
provided in Section 2.6(d)(i) shall be remitted by the Agent to the Swing Loan Lender.

          (c) Agent’s Assumption that Each Lender will Make Loans. Unless the Agent shall have
received notice from a Lender prior to the proposed date of any Borrowing (other than a Swing Loan
Borrowing) that such Lender will not make available to the Agent such Lender’s share of such
Borrowing, the Agent may assume that such Lender has made such share available on such date in
accordance with paragraph (b) of this Section 2.5 and may, in reliance upon such assumption, make
available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made
its share of the applicable Borrowing available to the Agent, then the applicable Lender agrees to
pay to the Agent forthwith on demand in immediately available funds such corresponding amount with
interest thereon, for each day from and including the date such amount is made available to the
Borrower but excluding the date of payment to the Agent, at the greater of the Federal Funds
Effective Rate and a rate determined by the Agent in accordance with banking industry rules on
interbank compensation, plus any administrative, processing or similar fees customarily charged by
the Agent in connection with the foregoing. If such Lender pays such amount to the Agent, then
such amount shall constitute such Lender’s Loan included in such Borrowing.

     2.6 Swing Loan Facility.

          (a) The Swing Loan. Subject to the terms and conditions hereinafter set forth, upon
notice by the Borrower made to the Swing Loan Lender in accordance with Section 2.6(b)(i), the
Swing Loan Lender hereby agrees to make Swing Loans to the Borrower from time to time on any
Business Day during the period between the Restatement Date and the Business Day immediately prior
to the expiration of the Revolving Credit Availability Period in an aggregate principal amount not
to exceed the Swing Loan Commitment. The Swing Loans shall be payable with interest accrued
thereon on the Business Day immediately prior to the expiration of the Revolving Credit
Availability Period. Amounts borrowed by the Borrower under this Section 2.6 may be repaid and
reborrowed, subject to the conditions hereof. At the time that each Swing Loan Borrowing is made,
such Borrowing shall be in an aggregate amount that is at least equal to $100,000 or any greater
multiple of $100,000. Notwithstanding any other provisions of this Agreement and in addition to
the Swing Loan Commitment limitation set forth above at no time shall the sum of (i) the aggregate
principal amount of all outstanding Swing Loans (after giving effect to all amounts requested and
the application of the proceeds thereof) plus (ii) the aggregate principal amount of all
outstanding Revolving Loans (after giving effect to all amounts requested and the application of
the proceeds thereof), plus (iii) the aggregate LC Exposure, exceed the aggregate amount of the
Revolving Credit Commitments of all the Lenders; provided, however, that subject to
the limitations set forth in this Section 2.6(a) from time to time the ratio of (x) the sum of the
aggregate Revolving Credit Exposure of the Swing Loan Lender (both in its capacity as the Swing
Loan Lender and in its capacity as a Revolving Credit Lender) to (y) the sum of the aggregate
Revolving Credit Exposure of all Lenders (including the Swing Loan Lender both in its capacity as
the Swing Loan Lender and in its capacity as a Revolving Credit Lender) may exceed its Applicable
Percentage.

- 32 -

 

          (b) Requests for Swing Loans.

          (i) When the Borrower desires the Swing Loan Lender to make a Swing Loan, it shall send
to the Agent and the Swing Loan Lender a written request (or telephonic notice, if
thereafter promptly confirmed in writing) (a “Swing Loan Request”), which request
shall set forth (x) the principal amount of the proposed Swing Loan, and (y) the proposed
date of Borrowing of such Swing Loan (which date shall be a Business Day). Each such Swing
Loan Request must be received by the Swing Loan Lender not later than 1:00 p.m. (Boston,
Massachusetts time) on the proposed date of Borrowing of the Swing Loan being requested.
Each Swing Loan Request shall be irrevocable and binding on the Borrower and shall obligate
the Borrower to borrow the Swing Loan from the Swing Loan Lender on the proposed date of
Borrowing.

          (ii) Upon satisfaction of the applicable conditions set forth in this Agreement, at or
before the close of business on the proposed date of Borrowing, the Swing Loan Lender shall
make the Swing Loan available to the Borrower by crediting the amount of the Swing Loan to
an account designated by the Borrower to the Swing Loan Lender; provided that Swing Loans
made to finance the reimbursement of an LC Disbursement under any Letter of Credit as
provided in Section 2.4(c) shall be remitted by the Agent to the Issuing Lender.

          (iii) Notwithstanding the foregoing, the Swing Loan Lender shall not advance any Swing
Loans after it has received notice from any Lender or any Credit Party that a Default under
Section 9.1(a)(ii) or an Event of Default has occurred and is continuing and stating that no
new Swing Loans are to be made until such Default or Event of Default has been cured or
waived in accordance with the provisions of this Agreement.

          (c) Interest on Swing Loans. Each Swing Loan shall be a Base Rate Loan and shall bear
interest for the account of the Swing Loan Lender thereof until repaid in full at the rate per
annum equal to the Base Rate plus the Applicable Margin for Base Rate Loans. The Borrower
promises to pay interest on the Swing Loans in arrears on each Interest Payment Date with respect
thereto. All such interest payable with respect to the Swing Loans shall be payable for the
account of the Swing Loan Lender.

          (d) Refundings of Swing Loans; Participations in Swing Loans.

          (i) The Swing Loan Lender, at any time in its sole and absolute discretion, may, on
behalf of the Borrower (which hereby irrevocably directs the Swing Loan Lender to act on its
behalf) request each Revolving Credit Lender, including the Swing Loan Lender, in its
capacity as a Revolving Credit Lender, to make a Revolving Loan in an amount equal to such
Revolving Credit Lender’s Applicable Percentage of the amount of the Swing Loans (the
“Refunded Swing Loans”) outstanding on the date such notice is given. Upon such
request, unless any of the Events of Default described in Section 9.1 (g) or (h) shall have
occurred (in which event the procedures of Section 2.6(d)(ii) shall apply), each Revolving
Credit Lender shall make the proceeds of its Revolving Loan available to the Agent, for the
account of the Swing Loan Lender, at the Agent’s office prior to 11:00 a.m. Boston,
Massachusetts time in funds immediately available on the Business Day next succeeding the
date such notice is given. The proceeds of such Revolving Loans shall be immediately
applied to repay the Refunded Swing Loans.

          (ii) If, prior to the making of a Revolving Loan pursuant to Section 2.6(d)(i), an
Event of Default described in Section 9.1 (g) or (h) shall have occurred, each Revolving
Credit Lender will, on the date such Revolving Loan was to have been made, purchase an
undivided participation interest in the Refunded Swing Loan in an amount equal to its
Applicable

- 33 -

 

Percentage of such Refunded Swing Loan. Each Revolving Credit Lender will immediately
transfer to the Swing Loan Lender, in immediately available funds, the amount of its
participation in such Refunded Swing Loan.

          (iii) 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 Refunded Swing Loan
pursuant to Section 2.6(d)(ii) above, 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
participation 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 as such payment is required to be returned by the
Swing Loan Lender.

          (iv) If any Revolving Credit Lender does not make available to the Swing Loan Lender
any amounts for the purpose of refunding a Swing Loan pursuant to Section 2.6(d)(i) above or
to purchase a participation interest in a Swing Loan pursuant to Section 2.6(d)(ii) above
(any such amounts payable by any Revolving Credit Lender being referred to herein as
“Refunding or Participation Amounts”) on the applicable due date with respect thereto, then
the applicable Revolving Credit Lender shall pay to the Swing Loan Lender forthwith on
demand such Refunding or Participation Amounts with interest thereon for each day from and
including the date such amount is made available to the Swing Loan Lender but excluding the
date of payment to the Swing Loan Lender, at the Federal Funds Effective Rate. If such
Lender pays such amount to the Swing Loan Lender, then such amount shall constitute such
Revolving Credit Lender’s Loan included in such refunding Borrowing or the consideration for
the purchase of such participation interest, as the case may be.

          (v) The failure or refusal of any Revolving Credit Lender to make available to the
Swing Loan Lender at the aforesaid time and place the amount of its Refunding or
Participation Amounts (x) shall not relieve any other Revolving Credit Lender from its
several obligations hereunder to make available to the Swing Loan Lender the amount of such
other Revolving Credit Lender’s Refunding or Participation Amounts and (y) shall not impose
upon such other Revolving Credit Lender any liability with respect to such failure or
refusal or otherwise increase the Revolving Credit Commitment of such other Revolving Credit
Lender.

          (vi) Each Revolving Credit Lender severally agrees that its obligation to make
available to the Swing Loan Lender its Refunding or Participation Amount as described above
shall (except to the extent expressly set forth in Section 2.6(d)(iv)) be absolute and
unconditional and shall not be affected by any circumstance, including (A) any set-off,
counterclaim, recoupment, defense or other right which such Revolving Credit Lender may have
against the Swing Loan Lender, the Borrower or any other Person for any reason whatsoever,
(B) the occurrence or continuance of any Default, the termination of the Revolving Credit
Commitments or any other condition precedent whatsoever, (C) any adverse change in the
condition (financial or otherwise) of any Credit Party or any other Person, (D) any breach
of any of the Loan Documents by any of the Credit Parties or any other Lender, or (E) any
other circumstance, happening or event, whether or not similar to any of the foregoing;
provided, however, that the obligation of each Revolving Credit Lender to
make available to the Swing Loan Lender its Refunding or Participation Amount in respect of
any Swing Loan is subject to the condition that the Swing Loan Lender believes in good faith
that all conditions under Section 6.2 were satisfied at the time such Swing Loan was made;
provided further that the Swing Loan

- 34 -

 

Lender shall have been deemed to have believed in good faith that such conditions were
satisfied unless, prior to the making of such Swing Loan, either (1) the Swing Loan Lender
shall have received notice from any other Lender or any Credit Party that a Default existed
as such time, or (2) the most recent Compliance Certificate received from the Borrower
indicating that a Default has occurred and is continuing and, in either case, such Default
had not been cured or waived at the time of the making of such Swing Loan.

     2.7 Expiration, Termination or Reduction of Commitments.

          (a) Expiration of Revolving Credit Commitments. Unless previously terminated, the
Revolving Credit Commitments shall expire at the close of business on the Revolving Credit Maturity
Date.

          (b) Reduction of Revolving Credit Commitments. The Borrower may at any time and from
time to time reduce the Revolving Credit Commitments or the Swing Loan Commitment; provided that
(i) each reduction of the Revolving Credit Commitments or the Swing Loan Commitment shall be in an
amount that is at least equal to $500,000 or any greater multiple of $100,000, and (ii) the
Borrower shall not reduce (A) the Revolving Credit Commitments if, after giving effect to any
concurrent repayment, the total Revolving Credit Exposure would exceed the total Revolving Credit
Commitments or (B) the Swing Loan Commitment if, after giving effect to any concurrent repayment of
the Swing Loans in accordance with Section 2.6 or prepayment of the Loans in accordance with
Section 2.9, the aggregate principal amount of outstanding Swing Loans would exceed the Swing Loan
Commitment, after giving effect to such termination or reduction. The Borrower shall notify the
Agent of any election to reduce the Revolving Credit Commitment or the Swing Loan Commitment at
least three Business Days prior to the effective date of such reduction, specifying the effective
date thereof. Each notice of reduction of the Revolving Credit Commitment or the Swing Loan
Commitment shall be irrevocable. Each reduction of the Revolving Credit Commitment shall be
permanent and shall be made ratably among the Revolving Credit Lenders in accordance with their
respective Revolving Credit Commitments.

          (c) Optional Termination of Commitments. The Borrower shall have the right at any
time to terminate the Commitments. The Borrower shall notify the Agent of any election to
terminate Commitments under this Section 2.7(c) at least three Business Days prior to the effective
date of such termination, specifying such election and the effective date thereof. Promptly
following receipt of any notice, the Agent shall advise the Lenders of the contents thereof. Each
notice delivered by the Borrower pursuant to this Section 2.7(e) shall be irrevocable; provided
that a notice of termination of Commitments delivered by the Borrower may state that such notice is
conditioned upon the effectiveness of other credit facilities, in which case such notice may be
revoked by the Borrower (by notice to the Agent on or prior to the specified effective date) if
such condition is not satisfied. Any termination of Commitments shall be permanent.

     2.8 Payments Generally; Pro Rata Treatment; Sharing of Set-Offs; Collection.

          (a) Payments Generally. The Borrower shall be obligated to make each payment required
to be made by the Borrower hereunder (whether of principal, interest, fees or reimbursement of LC
Disbursements, or otherwise) prior to 1:00 p.m. Boston, Massachusetts time, on the date when due,
in immediately available funds, in U.S. dollars, without set-off or counterclaim. Any amounts
received after such time on any date may, in the discretion of the Agent, be deemed to have been
received on the next succeeding Business Day for purposes of calculating interest thereon. All
payments shall be made to the Agent at its offices in Boston, Massachusetts, except that payments
pursuant to Sections 2.4, 2.11, 2.12, 11.3 and subsection 2.3(g) shall be made directly to the
Persons entitled thereto. The Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate

- 35 -

 

recipient promptly following receipt thereof, and the Borrower shall have no liability in the
event timely or correct distribution of such payments is not so made. If any payment shall be due
on a day that is not a Business Day, the date for payment shall be extended to the next succeeding
Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable
for the period of such extension. Notwithstanding anything to the contrary set forth herein, all
payments of interest, fees and other amounts (including, without limitation, payments of principal)
due to be paid by the Borrower hereunder shall be made through the automatic withdrawal from the
Borrower’s deposit account with the Agent of amounts equal to the amounts of such interest, fees or
other amounts due to be paid by the Borrower hereunder, and the Borrower hereby irrevocably
authorizes and directs the Agent to take such actions as may be necessary to effectuate such
automatic withdrawals, and, upon funding of any such withdrawal in an amount sufficient to make a
payment of interest, fees or other amounts due hereunder, the Borrower’s obligation to make such
payment shall be discharged. The Borrower expressly acknowledges and agrees that if any such
withdrawal is not in an amount sufficient to satisfy the amount of any interest, fees or other
amounts (including, without limitation, principal payments) due hereunder, the Borrower shall
remain obligated to pay the full amount of such interest, fees or other amounts as and when the
same shall become due.

          (b) Application of Payments. If at any time insufficient funds are received by and
available to the Agent to pay fully all amounts of principal, unreimbursed LC Disbursements,
interest and fees then due hereunder under any circumstances, including, without limitation during,
or as a result of the exercise by the Agent or the Lenders of remedies hereunder or under any other
Loan Document and applicable law, such funds shall be applied (i) first, to pay fees, costs and
expenses then due hereunder ratably among the parties entitled thereto under the Loan Documents in
accordance with the amounts of fees, costs and expenses then due to such parties, (ii) second, to
pay interest then due hereunder ratably among the parties entitled thereto under the Loan Documents
in accordance with the amount of interest then due to such parties; (iii) third, to pay principal
and unreimbursed LC Disbursements then due hereunder ratably among the parties entitled thereto in
accordance with the amounts of principal and unreimbursed LC Disbursements then due to such
parties, and (iv) fourth, to any other Obligations then due from the Credit Parties to the Agent,
the Issuing Lender or the Lenders.

          (c) Pro Rata Treatment. If any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of set-off or otherwise) on account of the Loans made by it
(other than pursuant to Sections 2.4, 2.6, 2.11 or 2.12), then, if there is any Unreimbursed Amount
outstanding in respect of which the Issuing Lender has not received payment in full from such
Lender pursuant to Section 2.4(c) (the amount of such Unreimbursed Amount being such Revolving
Credit Lender’s “LC Deficiency Amount”) or if there is any Swing Loan outstanding in
respect of which, pursuant to Section 2.6(d)(i) or (ii), the Swing Loan Lender has not received
payment in full from such Lender pursuant to Section 2.6(d)(i) or (ii) (the amount of such Swing
Loan being such Lender’s “SL Deficiency Amount”), such Lender shall both (a) purchase a
participation in such Unreimbursed Amount in an amount equal to the amount obtained by multiplying
the amount of such payment obtained by such Lender (the “Payment Amount”) by a fraction,
the numerator of which is such LC Deficiency Amount and the denominator of which is the sum of such
LC Deficiency Amount plus such SL Deficiency Amount (such sum being the “Aggregate
Deficiency” with respect to such Payment Amount), and (b) purchase a participation in such
Swing Loan in an amount equal to the amount obtained by multiplying such Payment Amount by a
fraction, the numerator of which is such SL Deficiency and the denominator of which is such
Aggregate Deficiency. If, after giving effect to the foregoing, any Lender shall, by exercising
any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans (or participations in LC Disbursements) (other than pursuant to
Sections 2.4, 2.6, 2.11 or 2.12), resulting in such Lender receiving payment of a greater
proportion of the aggregate principal amount of its Loans (and participations in LC Disbursements)
and accrued interest thereon than the proportion of such amounts received by any other Lender, then
the Lender receiving such greater proportion shall purchase

- 36 -

 

(for cash at face value) participations in the Loans (and LC Disbursements) of the other
Lenders to the extent necessary so that the benefit of such payments shall be shared by all the
Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on
their respective Loans (and participations in LC Disbursements); provided that (i) if any
such participations are purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price restored to the extent of
such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed
to apply to any payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans (or participations in LC Disbursements) to any assignee or
participant, other than to any Credit Party or any Subsidiary or Affiliate thereof (as to which the
provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to
the extent it may effectively do so under applicable law, that any Lender acquiring a participation
pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor
of the Borrower in the amount of such participation.

          (d) Agent’s Assumption that Borrower will Make Payments. Unless the Agent shall have
received notice from the Borrower prior to the date on which any payment is due to the Agent for
the account of the Lenders or the Issuing Lender entitled thereto (the “Applicable Recipient”)
hereunder that the Borrower will not make such payment, the Agent may assume that the Borrower has
made such payment on such date in accordance herewith and may, in reliance upon such assumption,
distribute to the Applicable Recipient the amount due. In such event, if the Borrower has not in
fact made such payment, then each Applicable Recipient severally agrees to repay to the Agent
forthwith on demand the amount so distributed to such Applicable Recipient with interest thereon,
for each day from and including the date such amount is distributed to it to but excluding the date
of payment to the Agent, at the Federal Funds Effective Rate.

          (e) Lender’s Failure to Make Payment. If any Lender shall fail to make any payment
required to be made by it pursuant to subsections 2.4(c), 2.5(c), 2.6(d)(i) or (ii), or 2.8(d),
then the Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any
amounts thereafter received by the Agent for the account of such Lender to satisfy such Lender’s
obligations under such subsection until all such unsatisfied obligations are fully paid.

     2.9 Prepayment of Loans.

          (a) Optional Prepayments of Loans. The Borrower shall have the right at any time and
from time to time to prepay the Revolving Loans (including the Swing Loans) in whole or in part,
subject to prior notice in accordance with subsection 2.9(d) in the case of LIBOR Loans, and
subject to the payment of any amounts due under subsection 2.3(g). The amount of any optional
prepayment in respect of the Revolving Loans shall be applied first, to the repayment of Swing
Loans and, second, to the repayment of Revolving Loans.

          (b) Mandatory Prepayments. The Borrower shall be obligated to, and shall, make
prepayments of the Loans hereunder (and, if applicable as provided in Section 2.9(c), reduce the
Revolving Credit Commitments hereunder) as follows:

          (i) Incurrence of Debt. Without limiting the obligation of the Borrower to
obtain the consent of the Required Lenders to any incurrence of Indebtedness not otherwise
permitted hereunder, the Borrower agrees, on the closing of any incurrence of Indebtedness
by any Credit Party (other than Indebtedness permitted pursuant to Section 8.1) to prepay
the Loans hereunder (and provide cash collateral for Total LC Exposure as specified in
subsection 2.4(h)), and, if applicable as provided in Section 2.9(c), the Revolving Credit
Commitments hereunder

- 37 -

 

shall be subject to automatic reduction, upon the date of such incurrence of
Indebtedness, in an aggregate amount equal to 100% of the amount of the Net Cash Payments
from such incurrence of Indebtedness received by any Credit Party, such prepayment and
reduction to be effected in each case in the manner and to the extent specified in
subsection 2.9(c) below.

          (ii) Sale of Assets. Without limiting the obligation of the Borrower to obtain
the consent of the Required Lenders to any Disposition not otherwise permitted hereunder,
the Borrower agrees, on or prior to the occurrence of any Disposition by any Credit Party,
to deliver to the Agent a statement certified by a Designated Financial Officer of the
Borrower, in form and detail reasonably satisfactory to the Agent, of the estimated amount
of the Net Cash Payments of such Disposition that will (on the date of such Disposition) be
received by any Credit Party in cash, indicating on such certificate, whether the Borrower
intends to reinvest such Net Cash Payments (to the extent Net Cash Payments from
Dispositions do not exceed $1,000,000 in the aggregate after the Effective Time) or will be
prepaying the Loans, as hereinafter provided, and the Borrower will be obligated to either
(A) cause the applicable Credit Party to reinvest such Net Cash Payments (to the extent Net
Cash Payments from Dispositions do not exceed $1,000,000 in the aggregate after the
Effective Time) within 180 days after receipt (or, if within such 180 day period the
Borrower or any Credit Party enters into contracts related to the reinvestment of such Net
Cash Payments, such longer period not to exceed 365 days after the original date of receipt
of such Net Cash Payments as is contemplated by such contracts) into replacement assets or
the repair of existing assets or (B) to the extent such Net Cash Payments exceed $1,000,000
in the aggregate after the Effective Time, prepay the Loans hereunder (and provide cover for
Total LC Exposure as specified in Section 2.4(h)), and, if applicable, as provided in
Section 2.9(c), the Revolving Credit Commitments hereunder shall be subject to automatic
reduction, as follows:

     (x) upon the date of such Disposition, or on the date (the
“Reinvestment Date”) which is 180 days after such date (or such
longer period not to exceed 365 days as contemplated by contracts related to
the reinvestment of such Net Cash Payments) if the Borrower had indicated on
the certificate delivered as hereinabove required that it intended to
reinvest the Net Cash Payments of such Disposition, in an aggregate amount
equal to 100% of the amount of such Net Cash Payments, to the extent
received by any Credit Party in cash on the date of such Disposition or, if
applicable, the Reinvestment Date to the extent of any Net Cash Payments not
so reinvested; and

     (y) thereafter, quarterly, on the date of the delivery by the Borrower
to the Administrative Agent pursuant to Section 7.1 of the financial
statements for any quarterly fiscal period or fiscal year, to the extent any
Credit Party shall receive Net Cash Payments during the quarterly fiscal
period ending on the date of such financial statements in cash under
deferred payment arrangements or Investments entered into or received in
connection with any Disposition, an amount equal to (A) 100% of the
aggregate amount of such Net Cash Payments minus (B) any transaction
expenses associated with Dispositions and not previously deducted in the
determination of Net Cash Payments plus (or minus, as the
case may be) (C) any other adjustment received or paid by any Credit Party
pursuant to the respective agreements giving rise to Dispositions and not
previously taken into account in the determination of the Net Cash Payments.

Prepayments of Loans (and cover for Total LC Exposure) shall be effected in each case in the manner
and to the extent specified in paragraph (c) of this Section 2.9; provided that if at the
time of any such Disposition a Default shall have occurred and be continuing, the Credit Parties
shall not have the right to

- 38 -

 

reinvest any Net Cash Payments and shall instead prepay the Loans by 100% of the amount of Net Cash
Payments received from such Disposition.

          (iii) Proceeds of Casualty Events. Upon the date 180 days following the
receipt by any Credit Party of the proceeds of insurance, condemnation award or other
compensation in respect of any Casualty Event affecting any property of any Credit Party (or
upon such earlier date as such Credit Party, as the case may be, shall have determined not
to repair or replace the property affected by such Casualty Event), except to the extent Net
Cash Payments from Casualty Events do not exceed $1,500,000 in the aggregate after the
Effective Time, the Borrower shall prepay the Loans (and provide cover for Total LC Exposure
as specified in Section 2.4(h)), and, if applicable as provided in Section 2.9(c), the
Revolving Credit Commitments shall be subject to automatic reduction, in an aggregate
amount, if any, equal to 100% of the Net Cash Payments from such Casualty Event not
theretofore applied or committed to be applied to the repair or replacement of such property
(it being understood that if Net Cash Payments committed to be applied are not in fact
applied within twelve months after receipt thereof, then such Net Cash Payments shall be
applied to the prepayment of Loans and cover for Total LC Exposure and reduction of
Commitments as provided in this clause (iii) at the expiration of such 180 day period), such
prepayment and reduction to be effected in each case in the manner and to the extent
specified in paragraph (c) of this Section 2.9; provided that if a Default has
occurred and is continuing, no Net Cash Payments from any Casualty Event may be applied to
the repair or replacement of any property and such Net Cash Payments shall be applied in
stead to prepay the Loans by 100% of the amount of Net Cash Payments received from such
Casualty Event.

          (c) Application.

          (i) In the event of any mandatory prepayment of Loans pursuant to subsection (b) of
this Section 2.9, the proceeds shall be applied as follows:

          (A) first, to the extent that a repayment of Swing Loans shall at such time be
required pursuant to Section 2.9(a), to the repayment of Swing Loans, but only to
such extent (with no reduction in the Commitments);

          (B) second, to the extent that total Revolving Credit Exposure shall at such
time exceed the total Revolving Credit Commitments at such time, such prepayment
shall be applied to the repayment of Revolving Loans to be shared and applied
ratably among the Revolving Credit Lenders in proportion to their respective
Revolving Credit Commitments (with no reduction in the Commitments); and

          (C) third, the amount of any mandatory prepayment shall be applied to repay
Revolving Loans, and, second, to provide cash collateral for Total LC Exposure as
specified in Section 2.4(h), with a corresponding permanent reduction in the
Revolving Credit Commitments.

          (d) Notification of Certain Prepayments. The Borrower shall notify the Agent by
telephone (confirmed by telecopy) of any voluntary prepayment of any LIBOR Loan not later than 1:00
p.m., Boston, Massachusetts time, three Business Days before the date of such prepayment. The
Borrower shall notify the Agent of any mandatory prepayment of the Loans pursuant to subsection
2.9(b) hereunder as soon as practicable. The Borrower shall notify the Agent by telephone
(confirmed by telecopy) of any prepayment of Swing Loans under Sections 2.9(a) or 2.9(b) not later
than 1:00 p.m., Boston, Massachusetts time, on the date of such prepayment, which date shall be a
Business Day. Each

- 39 -

 

such notice shall be irrevocable and shall specify the prepayment date and the principal
amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of any such
notice relating to a Borrowing (other than a Swing Loan Borrowing), the Agent shall advise the
Lenders of the contents thereof.

          (e) Prepayments Accompanied by Interest. All prepayments shall be accompanied by
accrued interest through the date of prepayment.

     2.10 Fees.

          (a) Unused Fee. The Borrower shall pay to the Agent for the account of each Lender
unused fees in respect of the Revolving Credit Commitments, in an aggregate amount equal to the
product of (x) the Applicable Unused Fee Rate, multiplied by (y) the daily average unused
amounts of the respective Revolving Credit Commitment of such Lender (excluding with respect to the
Swing Loan Lender the amount of any Swing Loans) during the period from and including the date on
which the Effective Time shall occur to but excluding the date on which the Revolving Credit
Commitments terminate; provided, that at any time when the Swing Loan Lender is the only
Lender hereunder, the amount of any Swing Loans outstanding shall be applied to reduce the daily
average unused amounts of the Revolving Credit Commitment of such Lender for purposes of this
Section 2.10(b). Accrued unused fees shall be payable monthly in arrears on the first day of each
month and on the date on which the Revolving Credit Commitments terminate. All unused fees shall
be computed on the basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

          (b) Letter of Credit Fees. The Borrower shall pay with respect to Letters of Credit
issued hereunder the following fees:

          (i) with respect to each standby or documentary Letter of Credit issued hereunder, to
the Agent for the accounts of the Revolving Credit Lenders a participation fee with respect
to their participations in such Letters of Credit which fee shall accrue at a rate per annum
equal to the Applicable Margin then used in determining interest on LIBOR Loans on the
average daily amount of such Lender’s LC Exposure (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the
Restatement Date to but excluding the later of the date on which there shall no longer be
any Letters of Credit outstanding hereunder, and

          (ii) with respect to each documentary or standby Letter of Credit issued hereunder, to
the Issuing Lender, a fronting fee equal to 0.25% per annum of the face amount of each
Letter of Credit, along with the Issuing Lender’s standard fees with respect to the
issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings
thereunder.

Accrued fees for Letters of Credit shall be computed on the basis of a year of 360 days and shall
be payable for the actual number of days elapsed (including the first day but excluding the last
day), and shall be payable monthly in arrears on the first day of each month and on the date the
Revolving Credit Commitments terminate, commencing on the first such date to occur after the date
hereof, provided that any such fees accruing after the date on which the Revolving Credit
Commitments terminate shall be payable on demand.

          (c) The Borrower agrees to pay to the Agent, for its own account, fees payable in the amounts
and at the times set forth in the Fee Letter and as otherwise separately agreed in writing between
the Borrower and the Agent.

 - 40 - 

 

          (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds.
Fees paid shall not be refundable under any circumstances, absent manifest error in the
determination thereof.

     2.11 Increased Costs.

          (a) If any Change in Law shall:

          (i) impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit extended by,
any Lender or the Issuing Lender; or

          (ii) impose on any Lender or the Issuing Lender or the London interbank market any
other condition affecting this Agreement or LIBOR Loans made by such Lender or any Letter of
Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any LIBOR Loan (or of maintaining its obligation to make any such Loan) or to increase
the cost to such Lender or the Issuing Lender of participating in, issuing or maintaining any
Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the
Issuing Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay
to such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will
compensate such Lender or the Issuing Lender, as the case may be, for such additional costs
incurred or reduction suffered.

          (b) If any Lender or the Issuing Lender reasonably determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return on such Lender’s
or the Issuing Lender’s capital or on the capital of such Lender’s or the Issuing Lender’s holding
company, if any, as a consequence of this Agreement or the Loans made by, or participations in
Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Lender, to a
level below that which such Lender or the Issuing Lender or such Lender’s or the Issuing Lender’s
holding company could have achieved but for such Change in Law (taking into consideration such
Lender’s or the Issuing Lender’s policies and the policies of such Lender’s or the Issuing Lender’s
holding company with respect to capital adequacy), then from time to time the Borrower will pay to
such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will
compensate such Lender or the Issuing Lender, or such Lender’s or the Issuing Lender’s holding
company, for any such reduction suffered.

          (c) A certificate of a Lender or the Issuing Lender setting forth the amount or amounts
necessary to compensate such Lender or the Issuing Lender or its holding company, as the case may
be, as specified in subsections 2.11(a) or 2.11(b) above shall be delivered to the Borrower and
shall be conclusive so long as it reflects a reasonable basis for the calculation of the amounts
set forth therein and does not contain any manifest error. The Borrower shall pay such Lender or
the Issuing Lender the amount shown as due on any such certificate within 10 days after receipt
thereof.

          (d) Failure or delay on the part of any Lender or the Issuing Lender to demand compensation
pursuant to this Section 2.11 shall not constitute a waiver of such Lender’s or the Issuing
Lender’s right to demand such compensation; provided that the Borrower shall not be
required to compensate a Lender or the Issuing Lender pursuant to this Section 2.11 for any
increased costs or reductions incurred more than six months prior to the date that such Lender or
the Issuing Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to
such increased costs or reductions and of such Lender’s or the Issuing Lender’s intention to claim
compensation therefor; provided further that, if the Change in Law giving rise to such
increased costs or reductions is (i) retroactive and (ii)

 - 41 - 

 

occurred within such six-month period, then the six-month period referred to above may be
extended to include the period of retroactive effect thereof, but in no event any period prior to
the Restatement Date.

     2.12 Taxes.

          (a) Any and all payments by or on account of any Obligations of the Borrower hereunder shall
be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes;
provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other
Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional sums payable under
this Section 2.12) the Agent, any Lender or the Issuing Lender (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower
shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

          (b) In addition, the Borrower shall pay all Other Taxes to the relevant Governmental Authority
in accordance with applicable law.

          (c) The Borrower shall indemnify the Agent, each Lender and the Issuing Lender, within 10 days
after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes
(including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts
payable under this Section 2.12) paid by the Agent, such Lender or the Issuing Lender, as the case
may be (and any penalties, interest and reasonable expenses arising therefrom or with respect
thereto during the period prior to the Borrower making the payment demanded under this paragraph
(c)), whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the Borrower by a Lender or the Issuing Lender, or by the Agent on its own
behalf or on behalf of a Lender or the Issuing Lender shall be conclusive absent manifest error.

          (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the
Borrower to a Governmental Authority, the Borrower shall deliver to the Agent the original or a
certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy
of the return reporting such payment or other evidence of such payment reasonably satisfactory to
the Agent.

          (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax
under the law of a jurisdiction in which the Borrower is located, or any treaty to which such
jurisdiction is a party, with respect to payments under this Agreement shall deliver to the
Borrower (with a copy to the Agent), at the time or times prescribed by applicable law or
reasonably requested by the Borrower, such properly completed and executed documentation prescribed
by applicable law as will permit such payments to be made without withholding or at a reduced rate.

     2.13 Mitigation Obligations; Replacement of Lenders

          (a) Designation of a Different Lending Office. If any Lender requests compensation
under Section 2.11, or if the Borrower is required to pay any additional amount to any Lender or
any Governmental Authority for the account of any Lender pursuant to Section 2.12, then such Lender
shall use reasonable efforts to designate a different lending office for funding or booking its
Loans hereunder, or to assign its rights and obligations hereunder to another of its offices,
branches or Affiliates, if, in the judgment of such Lender, such designation or assignment (i)
would eliminate or reduce amounts payable pursuant to Section 2.11 or 2.12, as the case may be, in
the future and (ii) would not subject such Lender to any material unreimbursed cost or expense and
would not otherwise be materially disadvantageous to

 - 42 - 

 

such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by
any Lender in connection with any such designation or assignment.

          (b) Replacement of Lenders. If any Lender requests compensation under Section 2.11,
or if the Borrower is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.11, or if any Lender defaults in its
obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon
notice to such Lender and the Agent, require such Lender to assign and delegate, without recourse
(in accordance with and subject to the restrictions contained in Section 11.4, all its interests,
rights and obligations under this Agreement to an assignee that shall assume such obligations
(which assignee may be another Lender, if a Lender accepts such assignment); provided that
(i) the Borrower shall have received the prior written consent of the Agent and the Issuing Lender,
which consents shall not unreasonably be withheld or delayed, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Loans (and participations in LC
Disbursements), accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such
assignment resulting from a claim for compensation under Section 2.11 or payments required to be
made pursuant to Section 2.12, such assignment will result in a reduction in such compensation or
payments. A Lender shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply.

ARTICLE III

Guarantee by Guarantors

     3.1 The Guarantee. The Guarantors hereby guarantee to each Lender, the Issuing Lender and the
Agent and their respective successors and permitted assigns the prompt payment in full when due
(whether at stated maturity, by acceleration or otherwise) of the Obligations. The Guarantors
hereby further agree that if the Borrower shall fail to pay in full when due (whether at stated
maturity, by acceleration or otherwise) any of the Obligations, the Guarantors will promptly pay
the same, without any demand or notice whatsoever, and that in the case of any extension of time of
payment or renewal of any of the Obligations, the same will be promptly paid in full when due
(whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such
extension or renewal.

     3.2 Obligations Unconditional. The obligations of the Guarantors under Section 3.1 are
absolute and unconditional irrespective of the value, genuineness, validity, regularity or
enforceability of this Agreement, the other Loan Documents or any other agreement or instrument
referred to herein or therein, or any substitution, release or exchange of any other guarantee of
or security for any of the Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise constitute a legal or
equitable discharge or defense of a surety or guarantor, it being the intent of this Section 3.2
that the obligations of the Guarantors hereunder shall be absolute and unconditional under any and
all circumstances. Without limiting the generality of the [text missing]

          (i) at any time or from time to time, without notice to such Guarantors, the time for
any performance of or compliance with any of the Obligations shall be extended, or such
performance or compliance shall be waived;

 - 43 - 

 

          (ii) any of the acts mentioned in any of the provisions hereof or of the other Loan
Documents or any other agreement or instrument referred to herein or therein shall be done
or omitted;

          (iii) the maturity of any of the Obligations shall be accelerated, or any of the
Obligations shall be modified, supplemented or amended in any respect, or any right
hereunder or under the other Loan Documents or any other agreement or instrument referred to
herein or therein shall be waived or any other guarantee of any of the Obligations or any
security therefor shall be released or exchanged in whole or in part or otherwise dealt
with; or

          (iv) any lien or security interest granted to, or in favor of, the Agent, the Issuing
Lender or any Lender or Lenders as security for any of the Obligations shall fail to be
perfected.

This Guarantee is a guaranty of payment and not of collection. The Guarantors hereby expressly
waive diligence, presentment, demand of payment, protest and all notices whatsoever, and any
requirement that the Agent, the Issuing Lender or any Lender exhaust any right, power or remedy or
proceed against the Borrower hereunder or under the other Loan Documents or any other agreement or
instrument referred to herein or therein, or against any other Person under any other guarantee of,
or security for, any of the Obligations.

     3.3 Reinstatement. The obligations of the Guarantors under this Article 3 shall be
automatically reinstated if and to the extent that for any reason any payment by or on behalf of
the Borrower in respect of the Obligations is rescinded or must be otherwise restored by any holder
of any of the Obligations, whether as a result of any proceedings in bankruptcy or reorganization
or otherwise, and each Guarantor agrees that it will indemnify the Agent, the Issuing Lender and
each Lender on demand for all reasonable costs and expenses (including fees and expenses of
counsel) incurred by the Agent, any Lender or the Issuing Lender in connection with such rescission
or restoration, including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or similar payment under
any bankruptcy, insolvency or similar law.

     3.4 Subrogation. Until such time as the Obligations shall have been indefensibly paid in
full, each of the Guarantors hereby waives all rights of subrogation or contribution, whether
arising by contract or operation of law (including, without limitation, any such right arising
under the Federal Bankruptcy Code of 1978, as amended) or otherwise by reason of any payment by it
pursuant to the provisions of this Article 3 and further agrees with the Borrower for the benefit
of each creditor of the Borrower (including, without limitation, the Agent, the Issuing Lender and
each Lender) that any such payment by it shall constitute a contribution of capital by such
Guarantor to the Borrower.

     3.5 Remedies. The Guarantors agree that, as between the Guarantors and the Lenders, the
Obligations of the Borrower hereunder may be declared to be forthwith due and payable as provided
in Section 9.2 (and shall be deemed to have become automatically due and payable in the
circumstances provided in Section 9.2) for purposes of Section 3.1 notwithstanding any stay,
injunction or other prohibition preventing such declaration (or such Obligations from becoming
automatically due and payable) as against the Borrower and that, in the event of such declaration
(or such Obligations being deemed to have become automatically due and payable), such Obligations
(whether or not due and payable by the Borrower) shall forthwith become due and payable by the
Guarantors for purposes of Section 3.1.

     3.6 Instrument for the Payment of Money. Each of the Guarantors hereby acknowledges that the
guarantee in this Article 3 constitutes an instrument for the payment of money, and consents and

 - 44 - 

 

agrees that the Agent, the Issuing Lender, or any Lender, at its sole option, in the event of
a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to
summary judgment or such other expedited procedure as may be available for a suit on a note or
other instrument for the payment of money.

     3.7 Continuing Guarantee. The guarantee in this Article 3 is a continuing guarantee, and
shall apply to all Obligations whenever arising.

     3.8 General Limitation on Amount of Obligations Guaranteed. In any action or proceeding
involving any state or non-U.S. corporate law, or any state or Federal or non-U.S. bankruptcy,
insolvency, reorganization or other law affecting the rights of creditors generally, if the
obligations of the Guarantors under Section 3.1 would otherwise be held or determined to be void,
invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the
amount of its liability under Section 3.1, then, notwithstanding any other provision hereof to the
contrary, the amount of such liability shall, without any further action by the Guarantors, any
Lender, Agent or other Person, be automatically limited and reduced to the highest amount that is
valid and enforceable and not subordinated to the claims of other creditors as determined in such
action or proceeding.

ARTICLE IV

Any of the foregoing terms which are defined in the Uniform Commercial Code shall have the meaning
provided in the Uniform Commercial Code, as amended and in effect from time to time, as
supplemented and expanded by the foregoing.

The term “Collateral” shall in no event include (a) any Energy Conservation Financing Collateral or

be rendered ineffective pursuant to the Uniform Commercial Code or any other applicable law
(including any federal, state or foreign bankruptcy, insolvency or similar law).

 - 46 - 

 

     4.2 Special Warranties and Covenants of the Credit Parties. Each Credit Party hereby warrants
and covenants to the Agent and the Lenders that:

          (a) Such Credit Party has delivered to the Agent a Perfection Certificate in substantially the
form of Exhibit C hereto. All information set forth in such Perfection Certificate is true
and correct in all material respects and the facts contained in such Perfection Certificate are
accurate in all material respects as of the date of this Agreement. Each Credit Party agrees to
supplement its Perfection Certificate promptly after obtaining information which would require a
material correction or addition to such Perfection Certificate.

          (b) No Credit Party will change its jurisdiction of organization, principal or any other place
of business, or the location of any Collateral from the locations set forth in the Perfection
Certificate delivered by such Credit Party, or make any change in its name or conduct its business
operations under any fictitious business name or trade name, without, in any such case, at least
fifteen (15) days’ prior written notice to the Agent; provided that the inventory of such Credit
Party may be in the possession of manufacturers or processors in any jurisdiction in which all
necessary UCC financing statements have been filed by the Agent and with respect to which the Agent
has received waiver letters from all landlords, warehousemen and processors in form and substance
acceptable to the Agent.

          (c) Except for Collateral that is obsolete or no longer used in their business, the Credit
Parties will keep the Collateral in good order and repair (normal wear excepted) and adequately
insured at all times in accordance with the provisions of Section 7.5. The Credit Parties will pay
promptly when due all taxes and assessments on the Collateral or for its use or operation, except
for taxes and assessments permitted to be contested as provided in Section 7.4. Following the
occurrence and during the continuance of an Event of Default, the Agent may at its option discharge
any taxes or Liens to which any Collateral is at any time subject (other than Permitted Liens), and
may, upon the failure of the Credit Parties to do so in accordance with this Agreement, purchase
insurance on any Collateral and pay for the repair, maintenance or preservation thereof, and each
Credit Party agrees to reimburse the Agent on demand for any payments or expenses incurred by the
Agent or the Lenders pursuant to the foregoing authorization and any unreimbursed amounts shall
constitute Obligations for all purposes hereof.

          (d) The Agent may at reasonable times request and each Credit Party shall deliver copies of
all customer lists and vendor lists.

          (e) To the extent, if any, that such Credit Party’s signature is required therefor, each
Credit Party will promptly execute and deliver to the Agent such financing statements and
amendments thereto, certificates and other documents or instruments as may be necessary to enable
the Agent to perfect or from time to time renew the security interest granted hereby, including,
without limitation, such financing statements and amendments thereto, certificates and other
documents as may be necessary to perfect a security interest in any additional Collateral hereafter
acquired by such Credit Party or in any replacements or proceeds thereof. Each Credit Party
authorizes and appoints the Agent, in case of need, to execute such financing statements,
certificates and other documents pertaining to the Agent’s security interest in the Collateral in
its stead if such Credit Party’s signature is required therefor and such Credit Party fails to so
execute such documents, with full power of substitution, as such Debtor’s attorney in fact. Each
Credit Party further agrees that a carbon, photographic or other reproduction of a security
agreement or financing statement is sufficient as a financing statement under this Agreement and
the other Loan Documents.

          (f) Each Credit Party hereby irrevocably authorizes the Agent, at any time and from time to
time, to file in any jurisdiction financing statements and amendments thereto that (i) indicate the
Collateral (x) as all assets of such Credit Party or words of similar effect, regardless of whether
any

 - 47 - 

 

particular asset falls within the scope of Article 9 of the Uniform Commercial Code of the
Commonwealth of Massachusetts or such jurisdiction or (y) as being of an equal or lesser scope or
with greater detail and (ii) which contain any other information required by Article 9 of the
Uniform Commercial Code (including Part 5 thereof) for the sufficiency or filing office acceptance
of any financing statement or amendment, including whether (A) any Credit Party is an organization,
the type of organization and any organization identification number issued to such Credit Party and
(B) in the case of a financing statement filed as a fixture filing or indicating Collateral as
as-extracted collateral or timber to be cut, a sufficient description of the real property to which
the Collateral relates. The Credit Parties agree to furnish any such information to the Agent
promptly upon reasonable request. Each Credit Party also ratifies its authorization for the Agent
to have filed in any Uniform Commercial Code jurisdiction any like initial financing statements or
amendments thereto if filed prior to the date hereof.

          (g) Each Credit Party agrees that it will join with the Agent in executing and, at its own
expense, will file and refile, or permit the Agent to file and refile such financing statements,
continuation statements and other documents (including, without limitation, this Agreement and
licenses to use software and other property protected by copyright), in such offices (including,
without limitation, the PTO, the United States Copyright Office, and appropriate state patent,
trademark and copyright offices), as the Agent may reasonably deem necessary or appropriate,
wherever required or permitted by law in order to perfect and preserve the rights and interests
granted to the Agent in Patents, Trademarks and Copyrights hereunder. Each Credit Party will give
the Agent notice of each office at which records of such Credit Party pertaining to all intangible
items of Collateral are kept. Except as may be provided in such notice, the records concerning all
intangible Collateral are and will be kept at the address shown in the respective Perfection
Certificate for such Credit Party as the principal place of business of such Credit Party.

          (h) The Credit Parties are the sole and exclusive owners of the websites and domain names
listed on Schedule 4.2 hereto and have registered such domain names with the applicable
authority for registration of the same which provides for the exclusive use by the Credit Parties
of such domain names. The websites do not contain, to the knowledge of the Credit Parties, any
material, the publication of which may result in (a) the violation of rights of any person or (b) a
right of any person against the publisher or distributor of such material.

          (i) The Credit Parties shall, annually by the end of the first calendar quarter following the
previous calendar year, provide written notice to the Agent of all applications for registration of
Patents, Trademarks or Copyrights, to the extent such applications exist, made during the preceding
calendar year. The Credit Parties shall file and prosecute diligently all applications for
registration of Patents, Trademarks or Copyrights now or hereafter pending that would be necessary
to the business of the Credit Parties to which any such applications pertain, and to do all acts,
in any such instance, necessary to preserve and maintain all rights in such registered Patents,
Trademarks or Copyrights unless such Patents, Trademarks or Copyrights are not material to the
business of the Credit Parties, as reasonably determined by the Credit Parties consistent with
prudent and commercially reasonable business practices. Any and all costs and expenses incurred in
connection with any such actions shall be borne by the Credit Parties. Except in accordance with

right to file a Patent, Trademark or Copyright application or any pending Patent, Trademark or
Copyright application or any registered Patent, Trademark or Copyright, in each case material to
its business, without the consent of the Agent.

          (j) The domain name servers used in connection with the domain names of the Credit Parties and

Agent. No Credit Party will cause a change in the identity of any domain name administrative
contact without 10 days’ prior notice to the Agent.

          (k) If any Credit Party is, now or at any time hereafter, a beneficiary under a letter of
credit in an amount equal to or greater than $100,000, such Credit Party shall promptly notify the
Agent thereof and, at the request and option of the Agent, such Credit Party shall, pursuant to an
agreement in form and substance satisfactory to the Agent, either (i) arrange for the issuer and
any confirmer or other nominated person of such letter of credit to consent to an assignment to the
Agent of the proceeds of the letter of credit or (ii) arrange for the Agent to become the
transferee beneficiary of the letter of credit, with the Agent agreeing, in each case, that the
proceeds of the letter of credit are to be applied by the Agent against the Obligations as provided
in this Agreement.

          (l) To the extent any Credit Party shall, now or at any time hereafter, hold or acquire any
promissory note or other instrument or tangible chattel paper (other than a construction contract

          (m) If, now or at any time hereafter, any Credit Party shall obtain or hold any investment

of the Commonwealth of Massachusetts, as amended and in effect from time to time) of such
Collateral.

          (n) No Credit Party holds any commercial tort claims, as defined in Article 9 of the Uniform
Commercial Code, except as indicated in the Perfection Certificates attached hereto as Exhibit
C. If any of the Credit Parties shall at any time acquire a commercial tort claim, such Credit
Party shall immediately notify the Lender in a writing signed by such Credit Party of the brief
details thereof and grant to the Lender in such writing a security interest therein and in the
proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and
substance reasonably satisfactory to the Lender.

          (o) If any Credit Party has accounts receivable in respect of which the account debtor is
located in Minnesota, the Credit Parties represent and warrant that the applicable Credit Party has
filed and shall file all legally-required Notice of Business Activities Reports and comparable
reports with the appropriate government authorities.

     4.3 Fixtures, etc. It is the intention of the parties hereto that none of the Collateral
shall become fixtures and, except as set forth on Schedule 4.3 attached hereto and except
for Collateral which becomes a fixture pursuant to any construction contract entered into by a
Credit Party the ordinary course of such Credit Party’s business, each Credit Party will take all
such reasonable action or actions as may be necessary to prevent any of the Collateral from
becoming fixtures. Without limiting the generality of the foregoing, each Credit Party will, if
requested by the Agent, use commercially reasonable efforts to obtain waivers of Liens, in form
satisfactory to the Agent, from each lessor of real property on which any of the Collateral is or
is to be located to the extent requested by the Agent.

     4.4 Right of Agent to Dispose of Collateral, etc. Upon the occurrence and during the
continuance of any Event of Default, but subject to the provisions of the Uniform Commercial Code
or

 - 49 - 

 

other applicable law, in addition to all other rights under applicable law and under the Loan
Documents, the Agent shall have the right to take possession of the Collateral and, in addition
thereto, the right to enter upon any premises on which the Collateral or any part thereof may be
situated and remove the same therefrom. The Agent may require the Credit Parties to make the
Collateral (to the extent the same is moveable) available to the Agent at a place to be designated
by the Agent or transfer any information related to the Collateral to the Agent by electronic
medium. Unless the Collateral is perishable or threatens to decline speedily in value or is of a
type customarily sold on a recognized market, the Agent will give the Credit Parties at least ten
(10) days’ prior written notice of the time and place of any public sale thereof or of the time
after which any private sale or any other intended disposition thereof is to be made. Any such
notice shall be deemed to meet any requirement hereunder or under any applicable law (including the
Uniform Commercial Code) that reasonable notification be given of the time and place of such sale
or other disposition.

     4.5 Right of Agent to Use and Operate Collateral, etc. Upon the occurrence and during the
continuance of any Event of Default, subject to the provisions of the Uniform Commercial Code or
other applicable law, the Agent shall have the right and power (a) to take possession of all or any
part of the Collateral, and to exclude the Credit Parties and all persons claiming under the Credit
Parties wholly or partly therefrom, and thereafter to hold, store, and/or use, operate, manage and
control the same, and (b) to grant a license to use, or cause to be granted a license to use, any
or all of the Patents, Trademarks and Copyrights (in the case of Trademarks, along with the
goodwill associated therewith), but subject to the terms of any licenses. Upon any such taking of
possession, the Agent may, from time to time, at the expense of the Credit Parties, make all such
repairs, replacements, alterations, additions and improvements to and of the Collateral as the
Agent may deem proper. In any such case the Agent shall have the right to manage and control the
Collateral and to carry on the business and to exercise all rights and powers of the Credit Parties
in respect thereto as the Agent shall deem best, including the right to enter into any and all such
agreements with respect to the operation of the Collateral or any part thereof as the Agent may see
fit; and the Agent shall be entitled to collect and receive all rents, issues, profits, fees,
revenues and other income of the same and every part thereof. Such rents, issues, profits, fees,
revenues and other income shall be applied to pay the expenses of holding and operating the
Collateral and of conducting the business thereof, and of all maintenance, repairs, replacements,
alterations, additions and improvements, and to make all payments which the Agent may be required
or may elect to make, if any, for taxes, assessments, insurance and other charges upon the
Collateral or any part thereof, and all other payments which the Agent may be required or
authorized to make under any provision of this Agreement (including reasonable legal costs and
attorneys’ fees). The Agent shall apply the remainder of such rents, issues, profits, fees,
revenues and other income as provided in Section 4.6.

     4.6 Proceeds of Collateral. After deducting all reasonable costs and expenses of collection,
storage, custody, sale or other disposition and delivery (including reasonable legal costs and
attorneys’ fees) and all other charges against the Collateral, the Agent shall apply the residue of
the proceeds of any such sale or disposition to the Obligations in accordance with the terms hereof
and any surplus shall be returned to the Credit Parties or to any Person or party lawfully entitled
thereto (including, if applicable, any holders of Subordinated Indebtedness). In the event the
proceeds of any sale, lease or other disposition of the Collateral are insufficient to pay all of
the Obligations in full, the Credit Parties will be liable for the deficiency, together with
interest thereon at the Post-Default Rate, and the cost and expenses of collection of such
deficiency, including (to the extent permitted by law), without limitation, reasonable attorneys’
fees, expenses and disbursements.

ARTICLE V

Representations and Warranties

     Each Credit Party represents and warrants to the Lenders, the Issuing Lender and the Agent, as
to itself and each other Credit Party, that:

     5.1 Organization; Powers. Each Credit Party has been duly formed or organized and is validly
existing and in good standing under the laws of its jurisdiction of organization. Each Credit
Party has all requisite power and authority to carry on its business as now conducted and is
qualified to do business in, and is in good standing in, every jurisdiction where such
qualification is required, except where the failure to have such power or authority or to be so
qualified or in good standing, individually or in the aggregate, could not reasonably be expected
to result in a Material Adverse Effect.

     5.2 Authorization; Enforceability. The borrowing of the Loans and the grant of security
interests pursuant to the Loan Documents are within the power and authority of the Credit Parties
and have been duly authorized by all necessary action on the part of the Credit Parties. This
Agreement and the other Loan Documents have been duly authorized, executed and delivered by the
Credit Parties and constitute legal, valid and binding obligations of the Credit Parties,
enforceable in accordance with their respective terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and
subject to general principles of equity, regardless of whether considered in a proceeding in equity
or at law.

     5.3 Governmental Approvals; No Conflicts. The borrowing of the Loans and the grant of the
security interests pursuant to the Loan Documents (a) do not require any consent or approval of,
registration or filing with, or any other action by, any Governmental Authority which has not been
obtained, except as disclosed on Schedule 5.3, (b) will not violate any applicable law,
policy or regulation or the organizational documents of the Credit Parties or any order of any
Governmental Authority, (c) will not violate or result in a default under any indenture, agreement
or other instrument binding upon the Credit Parties, or any assets, or give rise to a right
thereunder to require any payment to be made by the Credit Parties, and such violation or default
or right to payment would have a Material Adverse Effect, and (d) except for the Liens created by
the Loan Documents, will not result in the creation or imposition of any Lien on any asset of the
Credit Parties.

     5.4 Financial Condition; No Material Adverse Change.

          (a) The Credit Parties have heretofore delivered to the Lenders the following financial
statements:

          (i) the consolidated balance sheets and statements of operations, shareholders’ equity
and cash flows of the Borrower and all Subsidiaries of the Borrower, as of and for the
fiscal years ended December 31, 2005, December 31, 2006 and December 31, 2007, in each case,
audited and accompanied by an opinion of the Borrower’s independent public accountants;

          (ii) the unaudited consolidated balance sheet and statements of operations,
shareholders’ equity and cash flows of the Borrower and all Subsidiaries of the Borrower and
all Subsidiaries of the Borrower, as of and for the fiscal year-to-date period ended March
31, 2008, certified by a Designated Financial Officer that such financial statements fairly
present in all material respects the financial condition of the Borrower and all
Subsidiaries of the Borrower as at such date and the results of the operations of the
Borrower and all Subsidiaries of the Borrower

 - 51 - 

 

for the period ended on such date and that all such financial statements, including the
related schedules and notes thereto have been prepared in all material respects in
accordance with GAAP applied consistently throughout the periods involved, except as
disclosed on Schedule 5.4; and

          (iii) the projected consolidated balance sheets, statements of operations and cash
flows for the Borrower and all Subsidiaries of the Borrower on a monthly basis for fiscal
year 2008.

Except as disclosed on Schedule 5.4, such financial statements (except for the projections)
present fairly, in all material respects, the respective consolidated financial position and
results of operations and cash flows of the respective entities as of such respective dates and for
such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of
footnotes in the case of such unaudited or pro forma statements. The projections were prepared by
the Borrower in good faith and were based on assumptions that were reasonable when made, it being
understood, that actual results during the periods covered thereby may differ from the projected
results.

          (b) Except as disclosed on Schedule 5.4, since December 31, 2007, there has been no
material adverse change in the business, assets, operations or condition, financial or otherwise,

statements referred to in clause (ii) of paragraph (a) above.

          (c) None of the Credit Parties has on the date hereof any contingent liabilities, liabilities
for taxes, unusual forward or long-term commitments or unrealized or anticipated losses from any
unfavorable commitments in each case that are material and would need to be disclosed on financial

financial statements described in this Section 5.4, (ii) as provided for in Schedule 5.4
annexed hereto, or (iii) as otherwise permitted pursuant to this Agreement.

     5.5 Properties.

          (a) Each Credit Party has good and marketable title to, or valid, subsisting and enforceable
leasehold interests in, all its Property material to its business. All machinery and equipment of

to preserve and maintain the value and operating efficiency of such machinery and equipment.

          (b) Set forth on Schedule 5.5 hereto is a complete list of all Patents, Trademarks and
Copyrights. Each Credit Party owns, or is licensed to use, all Patents, Trademarks and Copyrights
and other intellectual property material to its business (“Proprietary Rights”), and to the
knowledge of the Borrower, the use thereof by the Credit Parties does not infringe upon the rights
of any other Person, except for any such infringements that, individually or in the aggregate,
could not reasonably be expected to result in a Material Adverse Effect.

          (c) Schedule 5.5 clearly identifies all Patents, Trademarks and Copyrights that have
been duly registered in, filed in or issued by the PTO or the United States Register of Copyrights
(collectively, the “Registered Proprietary Rights”). The Registered Proprietary Rights
have been properly maintained and renewed in accordance with all applicable provisions of law and
administrative regulations in the United States, as applicable. The Credit Parties have taken
commercially reasonable steps to protect the Registered Proprietary Rights material to their
businesses and to maintain the confidentiality of all Proprietary Rights that are not generally in
the public domain.

interest) under such lease, sublease or assignment. Except as specified in Schedule 5.5,
each agreement listed in clause (ii) of the immediately preceding sentence is in full force and
effect and the Borrower has no knowledge of any default that has occurred and is continuing
thereunder, and each such agreement constitutes the legal, valid and binding obligation of each
applicable Credit Party, enforceable against such Credit Party in accordance with its terms, except
as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or limiting creditors’ rights generally or by equitable principles.

     5.6 Litigation and Environmental Matters.

          (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Credit Parties, threatened against or
affecting any Credit Party as to which there is a reasonable possibility of an adverse
determination and that, if adversely determined, could reasonably be expected, individually or in
the aggregate, to result in a Material Adverse Effect (other than the Disclosed Matters set forth
in part (a) of Schedule 5.6).

Adverse Effect.

receivable had the capacity to contract at the time any contract or other document giving rise to
an account receivable was executed and such account debtor is not insolvent; and

of the following actions, at the same or different times: (i) terminate the Commitments, and
thereupon the Commitments shall terminate immediately, (ii) notify the Borrower that the
outstanding principal of the Loans shall bear

- 76 -

 

interest at the Post-Default Rate, and thereupon the outstanding principal of the Loans shall
bear interest at the Post-Default Rate, (iii) declare the Loans then outstanding to be due and
payable in whole (or in part, in which case any principal not so declared to be due and payable may
thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared
to be due and payable, together with accrued interest thereon and all fees and other Obligations,
shall become due and payable immediately, without presentment, demand, protest or other notice of
any kind, all of which are hereby waived by the Credit Parties, and (iv) the Agent, the Issuing
Lender, and the Lenders may exercise all of the rights as secured party and mortgagee hereunder or
under the other Loan Documents; and in case of any event with respect to the Credit Parties or any
Subsidiary described in clause (g) or (h) of Section 9.1, the Commitments shall automatically
terminate, the principal of the Loans then outstanding shall automatically bear interest at the

secured party and mortgagee hereunder or under the other Loan Documents to the extent permitted by
applicable law.

     9.3 Receivership. Without limiting the generality of the foregoing or limiting in any way the
rights of the Agent or the Lenders hereunder or under the other Loan Documents or otherwise under
applicable law, at any time after (i) the entire principal balance of any Loan shall have become
due and payable (whether at maturity, by acceleration or otherwise) and (ii) the Agent shall have
provided to the Borrower not less than ten (10) days’ prior written notice of its intention to
apply for a receiver, the Agent shall be entitled to apply for and have a receiver appointed under
state or federal law by a court of competent jurisdiction in any action taken by the Agent to
enforce the Lenders’ and the Agent’s rights and remedies hereunder and under the other Loan
Documents in order to manage, protect, preserve, sell and otherwise dispose of all or any portion
of the Collateral and continue the operation of the business of the Credit Parties, and to collect
all revenues and profits thereof and apply the same to the payment of all expenses and other
charges of such receivership, including the compensation of the receiver, and to the payment of the
Loans and other fees and expenses due hereunder and under the Loan Documents as aforesaid until a
sale or other disposition of such Collateral shall be finally made and consummated. TO THE EXTENT
PERMITTED BY APPLICABLE LAW, EACH CREDIT PARTY HEREBY IRREVOCABLY CONSENTS TO AND WAIVES ANY RIGHT
TO OBJECT TO OR OTHERWISE CONTEST THE APPOINTMENT OF A RECEIVER AS PROVIDED ABOVE. EACH CREDIT
PARTY (I) GRANTS SUCH WAIVER AND CONSENT KNOWINGLY AFTER HAVING DISCUSSED THE IMPLICATIONS THEREOF
WITH COUNSEL, (II) ACKNOWLEDGES THAT (A) THE UNCONTESTED RIGHT TO HAVE A RECEIVER APPOINTED FOR THE
FOREGOING PURPOSES IS CONSIDERED ESSENTIAL BY AGENT IN CONNECTION WITH THE ENFORCEMENT OF THE
LENDERS’ AND THE AGENT’S RIGHTS AND REMEDIES HEREUNDER AND UNDER THE OTHER LOAN DOCUMENTS, AND (B)
THE AVAILABILITY OF SUCH APPOINTMENT AS A REMEDY UNDER THE FOREGOING CIRCUMSTANCES WAS A MATERIAL
FACTOR IN INDUCING THE LENDERS TO MAKE THE LOANS TO THE BORROWER; AND (III) AGREES TO ENTER INTO
ANY AND ALL STIPULATIONS IN ANY LEGAL ACTIONS, OR AGREEMENTS OR OTHER INSTRUMENTS IN CONNECTION
WITH THE FOREGOING AND TO COOPERATE FULLY WITH THE AGENT AND THE LENDERS IN CONNECTION WITH THE
ASSUMPTION AND EXERCISE OF CONTROL BY THE RECEIVER OVER ALL OR ANY PORTION OF THE COLLATERAL. THE
LENDERS AND AGENT ACKNOWLEDGE AND AGREE THAT NOTHING IN THIS SECTION 9.3 SHALL BE DEEMED TO
CONSTITUTE A WAIVER OF THE RIGHT OF CREDIT PARTIES TO FILE FOR PROTECTION UNDER TITLE 11 OF THE
UNITED STATES CODE AT ANY TIME.

ARTICLE X

The Agent

     10.1 Appointment and Authorization.

          (a) Each of the Lenders and the Issuing Lender hereby irrevocably appoints the Agent as its
agent and authorizes the Agent to take such actions on its behalf and to exercise such powers as
are delegated to the Agent by the terms of this Agreement and the other Loan Documents, together
with such actions and powers as are reasonably incidental thereto. The provisions of this Article
X are solely for the benefit of the Agent, the Lenders and the Issuing Lender, and, except with
respect to Section 10.6, neither the Borrower nor any Credit Party shall have rights as a third
party beneficiary of any such provisions.

          (b) The Agent shall also act as the “collateral agent” under the Loan Documents and each of
the Lenders and the Issuing Lender hereby irrevocably appoints and authorizes the Agent to act as
the agent of such Lender and the Issuing Lender for purposes of acquiring, holding and enforcing
any and all Liens on Collateral granted by any of the Loan Parties to secure any of the
Obligations, together with such powers and discretion as are reasonably incidental thereto. In
this connection, the Agent, as “collateral agent” and any co-agents, sub-agents and
attorneys-in-fact appointed by the Agent pursuant to Section 10.5 or otherwise for purposes of
holding or enforcing any Lien on the Collateral (or any portion thereof) granted hereunder or under
any other Loan Document, or for exercising any rights and remedies thereunder at the direction of
the Agent), shall be entitled to the benefits of all provisions of this Article X and Article XI,
as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the
Loan Documents as if set forth in full herein with respect thereto.

     10.2 Agent’s Rights as Lender. The Person serving as Agent hereunder shall have the same
rights and powers in its capacity as a Lender as any other Lender and may exercise the same as
though it were not Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly
indicated or unless the context otherwise requires, include the Person serving as Agent hereunder
in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money
to, act as the financial advisor or in any other advisory capacity for and generally engage in any
kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person
were not the Agent hereunder and without any duty to account therefor to the Lenders.

     10.3 Duties As Expressly Stated. Neither the Agent nor the Issuing Lender shall have any
duties or obligations except those expressly set forth in this Agreement and the other Loan
Documents. Without limiting the generality of the foregoing, (a) neither the Agent nor the Issuing
Lender shall be subject to any fiduciary or other implied duties, regardless of whether a Default
has occurred and is continuing, (b) neither the Agent nor the Issuing Lender shall have any duty to
take any discretionary action or exercise any discretionary powers, except discretionary rights and
powers expressly contemplated by this Agreement and the other Loan Documents that the Agent or
Issuing Lender is required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as is required hereunder with respect to such action) and (c) except as
expressly set forth herein and in the other Loan Documents, neither the Agent nor the Issuing
Lender shall have any duty to disclose, or shall be liable for the failure to disclose, any
information relating to any Credit Party or any of their respective Subsidiaries that is
communicated to or obtained by the financial institution serving as the Agent or the Issuing Lender
or any of its Affiliates in any capacity. Neither the Agent nor the Issuing Lender shall be liable
for any action taken or not taken by it with the consent or at the request of the Required Lenders
(or such other number or percentage of the Lenders as is required hereunder with respect to such
action) or all of the Lenders if expressly required, or in the absence of its own gross

- 78 -

 

negligence or willful misconduct. Neither the Agent nor the Issuing Lender shall be deemed to
have knowledge of any Default other than a Default of the types specified in Section 9.1 (a) unless
and until written notice thereof is given to the Agent or the Issuing Lender by the Borrower or a
Lender, and the Agent shall not be responsible for or have any duty to ascertain or inquire into
(i) any statement, warranty or representation made in, or in connection with, this Agreement or the
other Loan Documents, (ii) the contents of any certificate, report or other document delivered
hereunder or under any of the other Loan Documents or in connection herewith of therewith, (iii)
the performance or observance of any of the covenants, agreements or other terms or conditions set
forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or
genuineness of this Agreement, the other Loan Documents or any other agreement, instrument or
document, or (v) the satisfaction of any condition set forth in Article 6 or elsewhere herein,
other than to confirm receipt of items expressly required to be delivered to the Agent or the
Issuing Lender. Neither the Agent nor the Issuing Lender shall, except to the extent the Agent
expressly instructed by the Required Lenders with respect to collateral security hereunder and
under the other Loan Documents, be required to initiate or conduct any litigation or collection
proceedings hereunder or under any other Loan Document; provided, however, that the Agent shall not
be required to take any action which exposes the Agent to personal liability or which is contrary
to the Loan Documents or applicable law.

     10.4 Reliance By Agent. The Agent and the Issuing Lender 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 believed by it to be genuine and to have been
signed or sent by the proper Person. The Agent and the Issuing Lender also may rely upon any
statement made to it orally or by telephone and believed by it to be made by the proper Person, and
shall not incur any liability for relying thereon. The Agent and the Issuing Lender may consult
with legal counsel (who may be counsel for the Borrower), 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. The Agent and the Issuing Lender shall be
fully justified in failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if
so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action (it being understood
that this provision shall not release the Agent from performing any action with respect to the
Borrower expressly required to be performed by it pursuant to the terms hereof) under this
Agreement. The Agent and the Issuing Lender shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the other Loan Documents in accordance with a
request of the Required Lenders (or, if so specified by this Agreement, all Lenders), and such
request and any action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Loans.

     10.5 Action Through Sub-Agents. The Agent and the Issuing Lender may perform any and all of
its duties, and exercise its rights and powers, by or through any one or more sub-agents appointed
by the Agent or the Issuing Lender. The Agent and the Issuing Lender and any such sub-agent may
perform any and all its duties and exercise its rights and powers through its Related Parties. The
exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the
Related Parties of the Agent and the Issuing Lender and any such sub-agent, and shall apply to its
activities in connection with the syndication of the credit facilities provided for herein as well
as activities of the Agent or the Issuing Lender.

     10.6 Resignation of Agent and Appointment of Successor Agent. Subject to the appointment and
acceptance of a successor Agent as provided in this paragraph, the Agent may resign at any time by
notifying the Lenders, the Issuing Lender and the Credit Parties. Upon any such resignation, the
Required Lenders shall have the right, in consultation with the Credit Parties, to appoint a
successor

- 79 -

 

Agent. If no successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Agent gives notice of its resignation,
then the retiring Agent may, on behalf of the Lenders and the Issuing Lender, appoint a successor
Agent, which shall be a bank with an office in Boston, Massachusetts or New York, New York, or an
Affiliate of any such bank. Upon the acceptance of a successor’s appointment as Agent hereunder,
such successor shall succeed to and become vested with all of the rights, powers, privileges and
duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of
its duties and obligations hereunder or under the other Loan Documents. The fees payable by the
Borrower to a successor Agent shall be the same as those payable to its predecessor unless
otherwise agreed between the Borrower and such successor. After the retiring Agent’s resignation
hereunder and under the other Loan Documents, the provisions of this Article and Section 11.3 shall
continue in effect for the benefit of such retiring Agent, its sub- agents and their respective
Related Parties in respect of any actions taken or omitted to be taken by any of them while the
retiring Agent was acting as Agent.

Any resignation by Bank of America as Agent pursuant to this Section shall also constitute its
resignation as Issuing Lender and Swing Loan Lender. Upon the acceptance of a successor’s
appointment as Agent hereunder, (a) such successor shall succeed to and become vested with all of
the rights, powers, privileges and duties of the retiring Issuing Lender and Swing Loan Lender, (b)
the retiring Issuing Lender and Swing Loan Lender shall be discharged from all of their respective
duties and obligations hereunder or under the other Loan Documents, and (c) the successor Issuing
Lender shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding
at the time of such succession or make other arrangements satisfactory to the retiring Issuing
Lender to effectively assume the obligations of the retiring Issuing Lender with respect to such
Letters of Credit.

     10.7 Lenders’ Independent Decisions. Each Lender acknowledges that it has, independently and
without reliance upon the Agent, the Issuing Lender or any other Lender and based on such documents
and information 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, the Issuing Lender or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its own decisions in
taking or not taking action under or based upon this Agreement and the other Loan Documents, any
related agreement or any document furnished hereunder or thereunder. Except as explicitly provided
herein, neither the Agent nor the Issuing Lender has any duty or responsibility, either initially
or on a continuing basis, to provide any Lender with any credit or other information with respect
to such operations, business, property, condition or creditworthiness, whether such information
comes into its possession on or before the first Event of Default or at any time thereafter.
Neither the Agent nor the Issuing Lender shall be deemed a trustee or other fiduciary on behalf of
any party.

     10.8 Indemnification. Each Lender agrees to indemnify and hold harmless the Agent and the
Issuing Lender (to the extent not reimbursed under Section 11.3, but without limiting the
obligations of the Borrower under Section 11.3), ratably in accordance with the aggregate principal
amount of the respective Commitments of and/or Loans and Total LC Exposure held by the Lenders (or,
if all of the Commitments shall have been terminated or expired, ratably in accordance with the
aggregate outstanding amount of the Loans and Total LC Exposure held by the Lenders), for any and
all liabilities (including pursuant to any Environmental Law), obligations, losses, damages,
penalties, actions, judgments, deficiencies, suits, costs, expenses (including reasonable
attorney’s fees) or disbursements of any kind and nature whatsoever that may be imposed on,
incurred by or asserted against the Agent or the Issuing Lender (including by any Lender) arising
out of or by reason of any investigation in or in any way relating to or arising out of any Loan
Document or any other documents contemplated by or referred to therein for any action taken or
omitted to be taken by the Agent or the Issuing Lender under or in respect of any of the Loan
Documents or other such documents or the transactions contemplated thereby

- 80 -

 

(including the costs and expenses that the Borrower is obligated to pay under Section 11.3,
but excluding, unless a Default has occurred and is continuing, normal administrative costs and
expenses incident to the performance of its agency duties hereunder) or the enforcement of any of
the terms hereof or thereof or of any such other documents; provided, however, that no Lender shall
be liable for any of the foregoing to the extent they are determined by a court of competent
jurisdiction in a final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of the party to be indemnified. The agreements set forth in this Section 10.8
shall survive the payment of all Loans and other obligations hereunder and shall be in addition to
and not in lieu of any other indemnification agreements contained in any other Loan Document.

     10.9 No Other Duties, Etc. Anything herein to the contrary notwithstanding, no Lender holding
a title listed on the cover page hereof shall have any powers, duties or responsibilities under
this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as Agent,
a Lender or the Issuing Lender hereunder.

     10.10 Agent May File Proofs of Claim. In case of the pendency of any proceeding under any
Debtor Relief Law or any other judicial proceeding relative to any Credit Party, the Agent
(irrespective of whether the principal of any Loan or Reimbursement Obligation shall then be due
and payable as herein expressed or by declaration or otherwise and irrespective of whether the
Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention
in such proceeding or otherwise.

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans, Reimbursement Obligations and all other Obligations that are owing
and unpaid and to file such other documents as may be necessary or advisable in order to have the
claims of Lenders, the Issuing Lender and the Agent (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Lenders, the Issuing Lender and the Agent
and their respective agents and counsel and all other amounts due the Lenders, the Issuing Lender
and the Agent under Sections 2.10 and 11.3) allowed in such judicial proceeding; and

          (b) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender and the L/C Issuer to make such
payments to the Agent and, in the event that the Agent shall consent to the making of such payments
directly to the Lenders and the Issuing Lender, to pay to the Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the Agent and its agents and
counsel, and any other amounts due the Agent under Sections 2.10 and 11.3. Nothing contained
herein shall be deemed to authorize the Agent to authorize or consent to or accept or adopt on
behalf of any Lender or the Issuing Lender any plan of reorganization, arrangement, adjustment or
composition affecting the Obligations or the rights of any Lender or the Issuing Lender or to
authorize the Agent to vote in respect of the claim of any Lender or the Issuing Lender in any such
proceeding.

     10.11 Guaranty Matters. Each Lender and the Issuing Lender hereby irrevocably authorizes the
Agent, at its option and in its discretion, to release any Guarantor from its obligations under the
Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.
Upon request by the Agent at any time, each Lender and the Issuing Lender will confirm in writing
the Agent’s authority to release any Guarantor from its obligations under the Guaranty pursuant to
this Section 10.11.

- 81 -

 

     10.12 Collateral Matters.

          (a) Each Lender and the Issuing Lender hereby irrevocably authorizes and directs the Agent to
enter into the Collateral Documents for the benefit of such Lender and the Issuing Lender. Each
Lender and the Issuing Lender hereby agrees, and each holder of any Note by the acceptance thereof
will be deemed to agree, that, except as otherwise set forth in Section 11.2, any action taken by
the Required Lenders, in accordance with the provisions of this Agreement or the Collateral
Documents, and the exercise by the Required Lenders of the powers set forth herein or therein,
together with such other powers as are reasonably incidental thereto, shall be authorized and
binding upon all of Lenders and the Issuing Lender. The Agent is hereby authorized (but not
obligated) on behalf of all of Lenders and the Issuing Lender, without the necessity of any notice
to or further consent from any Lender or the Issuing Lender from time to time prior to, an Event of
Default, to take any action with respect to any Collateral or Collateral Documents which may be
necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the
Collateral Documents.

          (b) Each Lender and the Issuing Lender hereby irrevocably authorize the Agent, at its option
and in its discretion:

          (i) to release any Lien on any property granted to or held by the Agent under any Loan
Document (A) upon termination of the Commitments and payment in full of all Obligations
(other than contingent indemnification obligations) and the expiration or termination of all
Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory
to Agent and the Issuing Lender shall have been made), (B) that is sold or to be sold as
part of or in connection with any sale permitted hereunder or under any other Loan Document,
(C) that is sold, transferred, assigned, financed or otherwise disposed of in connection
with an Energy Conservation Project or Renewable Energy Project, (D) subject to Section
11.2, if approved, authorized or ratified in writing by the Required Lenders, (E) in
connection with any foreclosure sale or other disposition of Collateral after the occurrence
of an Event of Default or (F) as otherwise provided under Section 11.13; and

          (ii) to subordinate any Lien on any property granted to or held by the Agent under any
Loan Document to the holder of any Lien on such property that is permitted by this Agreement
or any other Loan Document.

Upon request by the Agent at any time, each Lender and the Issuing Lender will confirm in writing
the Agent’s authority to release or subordinate its interest in particular types or items of
Collateral pursuant to this Section 10.12.

          (c) Subject to (b) above, the Agent is hereby irrevocably authorized by each Lender and the
Issuing Lender, to execute such documents as may be necessary to evidence the release or
subordination of the Liens granted to the Agent for the benefit of the Agent, the Lenders and the
Issuing Lender herein or pursuant hereto upon the applicable Collateral; provided that (i) the
Agent shall not be required to execute any such document on terms which, in the Agent’s opinion,
would expose the Agent to or create any liability or entail any consequence other than the release
or subordination of such Liens without recourse or warranty and (ii) such release or subordination
shall not in any manner discharge, affect or impair the Obligations or any Liens upon (or
obligations of the Borrower or any other Credit Party in respect of) all interests retained by the
Borrower or any other Credit Party, including the proceeds of the sale, all of which shall continue
to constitute part of the Collateral. In the event of any sale or transfer of Collateral, or any
foreclosure with respect to any of the Collateral, the Agent shall be authorized to deduct all
expenses reasonably incurred by the Agent from the proceeds of any such sale, transfer or
foreclosure.

- 82 -

 

          (d) The Agent shall have no obligation whatsoever to any Lender, the Issuing Lender or any
other Person to assure that the Collateral exists or is owned by the Borrower or any other Credit
Party or is cared for, protected or insured or that the Liens granted to the Agent herein or in any
of the Collateral Documents or pursuant hereto or thereto have been properly or sufficiently or
lawfully created, perfected, protected or enforced or are entitled to any particular priority, or
to exercise or to continue exercising at all or in any manner or under any duty of care, disclosure
or fidelity any of the rights, authorities and powers granted or available to Agent in this Section
10.12 or in any of the Collateral Documents, it being understood and agreed that in respect of the
Collateral, or any act, omission or event related thereto, the Agent may act in any manner it may
deem appropriate, in its sole discretion, given the Agent’s own interest in the Collateral as one
of the Lenders and that the Agent shall have no duty or liability whatsoever to the Lenders or the
Issuing Lender.

          (e) Each Lender and the Issuing Lender hereby appoints each other Lender as agent for the
purpose of perfecting the Lenders’ and the Issuing Lender’s security interest in assets which, in
accordance with Article 9 of the UCC can be perfected only by possession. Should any Lender or the
Issuing Lender (other than the Agent) obtain possession of any such Collateral, such Lender or the
Issuing Lender shall notify the Agent thereof, and, promptly upon the Agent’s request therefor
shall deliver such Collateral to the Agent or in accordance with the Agent’s instructions.

          (b) Electronic Communications. Notices and other communications to Lenders and the
Issuing Lender hereunder may be delivered or furnished by electronic communication (including
e-mail and Internet or intranet websites) pursuant to procedures approved by the Agent, provided
that the foregoing shall not apply to notices to any Lender or the Issuing Lender pursuant to
Article II if such Lender or the Issuing Lender, as applicable has notified the Agent that it is
incapable of receiving notices under such Article by electronic communication. The Agent or the
Borrower may, in its discretion, agree to accept notices and other communications to it hereunder

MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR
FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH BORROWER
MATERIALS OR THE PLATFORM. In no event shall the Agent or any of its Related Parties
(collectively, the “Agent Parties”) have any liability to the Borrower, any Lender, the Issuing
Lender or any other Person for losses, claims, damages, liabilities or expenses of any kind
(whether in tort, contract or otherwise) arising out of the Borrower’s or the Agent’s transmission
of Borrower Materials through the Internet, except to the extent that such losses, claims, damages,
liabilities or expenses are determined by a court of competent jurisdiction to have resulted from
the gross negligence or willful misconduct of such Agent Party; provided, however, that in no event
shall any Agent Party have any liability to the Borrower, any Lender, the Issuing Lender or any
other Person for indirect, special, incidental, consequential or punitive damages (as opposed to
direct or actual damages).

          (d) Change of Address, Etc. Each of the Borrower, the Agent, the Issuing Lender and
Swing Loan Lender may change its address, telecopier or telephone number for notices and other

the Borrower, the Agent, the Issuing Lender and Swing Loan Lender. In addition, each Lender agrees
to notify the Agent from time to time to ensure that the Agent has on record (i) an effective
address, contact name, telephone number, telecopier number and electronic mail address to which
notices and other communications may be sent and (ii) accurate wire instructions for such Lender.

delegate, in accordance with such Public Lender’s compliance procedures and applicable Law,
including United States Federal and state securities Laws, to make reference to Borrower Materials

- 84 -

 

          (e) Reliance by Agent, Issuing Lender and Lenders. The Agent, the Issuing Lender and
the Lenders shall be entitled to rely and act upon any notices (including telephonic Advance
Requests) purportedly given by or on behalf of the Borrower even if (i) such notices were not made
in a manner specified herein, were incomplete or were not preceded or followed by any other form of
notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any
confirmation thereof. The Borrower shall indemnify the Agent, the Issuing Lender, each Lender and
the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from
the reliance by such Person on each notice purportedly given by or on behalf of the Borrower. All
telephonic notices to and other telephonic communications with the Agent may be recorded by the
Agent, and each of the parties hereto hereby consents to such recording.

     11.2 Waivers; Amendments.

          (a) No failure or delay by the Agent, the Issuing Lender, or the Lenders in exercising any
right or power hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such
a right or power, preclude any other or further exercise thereof or the exercise of any other right
or power. The rights and remedies of the Agent, the Issuing Lender, and the Lenders hereunder and
under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of this Agreement or consent to any
departure by any Credit Party or Subsidiary therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) of this Section 11.2, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which given. Without
limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit
shall not be construed as a waiver of any Default, regardless of whether the Agent, any Lender or
the Issuing Lender may have had notice or knowledge of such Default at the time.

          (b) Neither this Agreement nor any other Loan Document nor any provision hereof or thereof may
be waived, amended or modified except pursuant to an agreement or agreements in writing entered
into by the Borrower and the Required Lenders or by the Borrower and the Agent with the written
consent of the Required Lenders and the Agent; provided that no such agreement shall:

          (i) increase the Commitment of any Lender without the written consent of such Lender
and the Agent;

          (ii) reduce the principal amount of any Loan or Reimbursement Obligation or reduce the
rate of interest thereon (other than the decision not to charge, or to cease to charge,
Post-Default Interest), or reduce any fees payable hereunder, without the written consent of
each Lender affected thereby;

          (iii) postpone the scheduled date of payment of the principal amount of any Loan or
Reimbursement Obligation other than mandatory prepayments of the Loans required under
Section 2.9(b), or any interest thereon, or any fees payable hereunder, or reduce the amount
of, waive or excuse any such payment, change the maturity date of any Loan, or postpone the
scheduled date of expiration of any Commitment, or extend the ultimate expiration date of
any Letter of Credit beyond the Revolving Credit Maturity Date, without the written consent
of each Lender affected thereby;

          (iv) except as expressly set forth in clause (x) below, change Section 2.9(c) in a
manner that would alter the application of prepayments thereunder, or change Section 2.8(b)
or

- 85 -

 

(c) in a manner that would alter the pro rata sharing of payments required thereby,
without in each case the written consent of each Lender;

          (v) alter the rights or obligations of the Borrower to prepay Loans (other than
mandatory prepayments of Loans under Section 2.9(b)) without the written consent of each
Lender affected thereby;

          (vi) change any of the provisions of this Section 11.2 or the definition of “Required
Lenders” or any other provision hereof specifying the number or percentage of Lenders
required to waive, amend or modify any rights hereunder or under any other Loan Document or
make any determination or grant any consent hereunder or thereunder, without the written
consent of each Lender;

          (vii) release any of the Guarantors from its obligations in respect of its Guarantee
under Article 3 or release any material portion of the Collateral (or terminate any Lien
with respect thereto), except as expressly permitted in this Agreement, without the written
consent of each Lender;

          (viii) waive any of the conditions precedent specified in Section 6.1 without the
written consent of each Lender and the Agent; or

          (ix) subordinate the Loans to any other Indebtedness, without the written consent of
each Lender;

provided
further that no such agreement shall amend, modify or otherwise affect the
rights or duties of the Agent, the Swing Loan Lender or the Issuing Lender hereunder without the
prior written consent of the Agent, the Swing Loan Lender or the Issuing Lender, as the case may
be.

          (c) Anything in this Agreement to the contrary notwithstanding, no waiver or modification of
any provision of this Agreement that has the effect (either immediately or at some later time) of
enabling the Borrower to satisfy a condition precedent to the making of any of Loan shall be
effective against all Lender unless the Required Lenders shall have concurred with such waiver or
modification.

     11.3 Expenses; Indemnity: Damage Waiver.

          (a) The Credit Parties jointly and severally agree to pay, or reimburse the Agent or the
Lenders, as applicable, for paying, (i) all reasonable out-of-pocket expenses incurred by the Agent
and its Affiliates, including the reasonable fees, charges and disbursements of Special Counsel, in
connection with the syndication of the credit facilities provided for herein, the preparation of
this Agreement and the other Loan Documents or any amendments, modifications or waivers of the
provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall
be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Lender in
connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand
for payment thereunder, (iii) all out-of-pocket expenses incurred by the Agent, the Issuing Lender,
or any Lender, including the fees, charges and disbursements of any counsel for the Agent, the
Issuing Lender, or any Lender, in connection with the enforcement or protection of their rights in
connection with this Agreement and the other Loan Documents, including their rights under this
Section 11.3, or in connection with the Loans made or Letters of Credit issued hereunder, including
in connection with any workout, restructuring or negotiations in respect thereof, and (iv) all
Other Taxes levied by any Governmental Authority in respect of this Agreement or any of the other
Loan Documents or any other document referred to herein or therein

- 86 -

 

and all costs, expenses, taxes, assessments and other charges incurred in connection with any
filing, registration, recording or perfection of any security interest contemplated by any Loan
Document or any other document referred to therein.

          (b) The Credit Parties jointly and severally agree to indemnify the Agent, the Issuing Lender,
each Lender and each Related Party of any of the foregoing Persons (each such Person being called
an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including the fees, charges and disbursements of any
counsel for any Indemnitee and settlement costs, incurred by or asserted against any Indemnitee
arising out of, in connection with, or as a result of (i) the execution or delivery of this
Agreement, the other Loan Documents or any agreement or instrument contemplated hereby, the
performance by the parties hereto and thereto of their respective obligations hereunder or
thereunder or the consummation of the transactions contemplated hereby or any other transactions
contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use of the proceeds
therefrom (including any refusal by the Issuing Lender to honor a demand for payment under a Letter
of Credit if the documents presented in connection with such demand do not strictly comply with the
terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property owned, leased or operated by any Credit Party or any Subsidiary,
or any Environmental Liability related in any way to any Credit Party or any Subsidiary, or (iv)
any actual or prospective claim, litigation, investigation or proceeding relating to any of the
foregoing, whether based on contract, tort or any other theory and regardless of whether any
Indemnitee is a party thereto; provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related
expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to
have resulted from the gross negligence or willful misconduct of such Indemnitee.

          (c) To the extent that the Credit Parties fail to pay any amount required to be paid by them
to the Agent under paragraph (a) or (b) of this Section 11.3, each Lender severally agrees to pay
to the Agent such Lender’s Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that
the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the
case may be, was incurred by or asserted against the Agent in its capacity as such. To the extent
that the Credit Parties fail to pay any amount required to be paid by them to the Issuing Lender
under paragraph (a) or (b) of this Section 11.3, each Revolving Credit Lender severally agrees to
pay to the Issuing Lender such Lender’s Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage, liability or
related expense, as the case may be, was incurred by or asserted against the Issuing Lender in its
capacity as such.

          (d) To the extent permitted by applicable law, none of the Credit Parties shall assert, and
each Credit Party hereby waives, any claim against any Indemnitee, on any theory of liability, for
special, indirect, consequential or punitive damages (as opposed to direct or actual damages)
arising out of, in connection with, or as a result of, this Agreement, the other Loan Documents or
any agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby,
any Loan or Letter of Credit or the use of the proceeds thereof.

          (e) All amounts due under this Section 11.3 shall be payable within ten (10) Business Days
after written demand therefor.

          (f) The agreements in this Section 11.3 shall survive the resignation of the Agent, the
Issuing Lender and the Swing Loan Lender, the termination of the Commitments and the repayment,
satisfaction or discharge of all other Obligations.

     11.4 Successors and Assigns.

          (a) Successors and Assigns, Generally. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that no Credit Party may assign or otherwise transfer any of its
rights or obligations hereunder without the prior written consent of each Lender, the Issuing
Lender and the Agent no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this
Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this
Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions
of subsection (f) of this Section (and any other attempted assignment or transfer by any party
hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their respective successors and
assigns permitted hereby and, to the extent expressly contemplated hereby, Participants to the
extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby,
the Related Parties of the Agent, the Issuing Lender, and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

          (b) Assignments by Lenders. Any Lender may at any time assign to one or more
assignees all or a portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans (including for purposes of this subsection (b),
participations in L/C Obligations and in Swing Line Loans) at the time owing to it); provided that
any such assignment shall be subject to the following conditions:

          (i) Minimum Amounts:

          (A) in the case of an assignment of the entire remaining amount of the
assigning Lender’s Commitment and the Loans at the time owing to it or in the case
of an assignment to a Lender or an Affiliate of a Lender no minimum amount need be
assigned; and

          (B) in any case not described in subsection (b)(i)(A) of this Section, the
aggregate amount of the Commitment (which for this purpose includes Loans
outstanding thereunder) or, if the Commitment is not then in effect, the principal
outstanding balance of the Loans of the assigning Lender subject to each such
assignment, determined as of the date the Assignment and Assumption with respect to
such assignment is delivered to Agent or, if “Trade Date” is specified in the
Assignment and Assumption, as of the Trade Date, shall not be less than $5,000,000,
unless each of Agent and, so long as no Event of Default has occurred and is
continuing, the Borrower otherwise consents (each such consent not to be
unreasonably withheld or delayed); provided, however, that concurrent assignments to
members of an Assignee Group and concurrent assignments from members of an Assignee
Group to a single Eligible Assignee (or to an Eligible Assignee and members of its
Assignee Group) will be treated as a single assignment for purposes of determining
whether such minimum amount has been met;

          (ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender’s rights and obligations
under this Agreement with respect to the Loans or the Commitment assigned, except that this
clause (ii) shall not apply to the Swing Loan Lender’s rights and obligations in respect of
Swing Loans;

- 88 -

 

          (iii) Required Consents. No consent shall be required for any assignment
except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

          (A) the consent of Borrower (such consent not to be unreasonably withheld or
delayed) shall be required for any assignment to a Competitor and for any other
assignment; provided, that the consent of the Borrower shall not be required in
connection with any assignment to a non-Competitor if (1) an Event of Default has
occurred and is continuing at the time of such assignment or (2) such assignment is
to a Lender or an Affiliate of a Lender;

          (B) the consent of Agent (such consent not to be unreasonably withheld or
delayed) shall be required for assignments in respect of any Revolving Credit
Commitment if such assignment is to a Person that is not a Lender or an Affiliate of
such Lender; and

          (C) the consent of the Issuing Lender (such consent not to be unreasonably
withheld or delayed) shall be required for any assignment that increases the
obligation of the assignee to participate in exposure under one or more Letters of
Credit (whether or not then outstanding).

          (iv) Assignment and Assumption. The parties to each assignment shall execute
and deliver to the Agent an Assignment and Assumption, together with a processing and
recordation fee in the amount of $3,500.00; provided, however, that the Agent may, in its
sole discretion, elect to waive such processing and recordation fee in the case of any
assignment. The assignee, if it is not a Lender, shall deliver to Agent an Administrative
Questionnaire.

          (v) No Assignment to Borrower. No such assignment shall be made to Borrower or
any of Borrower’s Affiliates or Subsidiaries.

          (vi) No Assignment to Natural Persons. No such assignment shall be made to a
natural person.

Subject to acceptance and recording thereof by the Agent pursuant to subsection (c) of this
Section, from and after the effective date specified in each Assignment and Assumption, the
assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations
under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be
entitled to the benefits of Sections 2.11, 2.12 and 11.3 with respect to facts and circumstances
occurring prior to the effective date of such assignment. Upon request, the Borrower (at its
expense) shall execute and deliver a Note to the assignee Lender. Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with this subsection
shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with subsection (d) of this Section.

          (c) Register. The Agent, acting solely for this purpose as an agent of the Borrower,
shall maintain at the Agent’s office a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the Commitments of, and
principal amounts of the Loans and Reimbursement Obligations owing to, each Lender pursuant to the
terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive,
and the

- 89 -

 

Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for inspection by the
Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

          (d) Participations. Any Lender may at any time, without the consent of, or notice to,
the Borrower or the Agent, sell participations to any Person (other than a natural person or
Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in
all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or
a portion of its Commitment and/or the Loans (including such Lender’s participations in
Reimbursement Obligations and/or Swing Loans) owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and (iii) the
Borrower, the Agent, the Issuing Lender and the Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation shall provide that
such Lender shall retain the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the Participant, agree to
any amendment, waiver or other modification described in the first proviso to Section 11.2 that
affects such Participant. Subject to subsection (e) of this Section, the Borrower agrees that each
Participant shall be entitled to the benefits of Sections 2.11 and 2.12 to the same extent as if it
were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled to the benefits
of Section 11.8 as though it were a Lender, provided such Participant agrees to be subject to
Section 2.8 as though it were a Lender.

          (e) Limitations upon Participant Rights. A Participant shall not be entitled to
receive any greater payment under Section 2.11 or 2.12 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with the Borrower’s prior written consent. A
Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 2.12 unless Borrower is notified of the participation sold to such Participant
and such Participant agrees, for the benefit of Borrower, to comply with Section 2.12(e) as though
it were a Lender.

          (f) Certain Pledges. Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement (including under its Note, if any) to
secure obligations of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any
of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

          (g) Resignation as Issuing Lender or Swing Loan Lender. Notwithstanding anything to
the contrary contained herein, if at any time Bank of America assigns all of its Commitment and
Loans pursuant to subsection (b) above, Bank of America may, (i) upon 30 days’ notice to the
Borrower and the Lenders, resign as Issuing Lender and/or (ii) upon 30 days’ notice to the
Borrower, resign as Swing Loan Lender. In the event of any such resignation as Issuing Lender or
Swing Loan Lender, the Borrower shall be entitled to appoint from among Lenders a successor Issuing
Lender or Swing Loan Lender hereunder; provided, however, that no failure by the Borrower
to appoint any such successor shall affect the resignation of Bank of America as Issuing Lender or
Swing Loan Lender, as the case may be. If Bank of America resigns as Issuing Lender, it shall
retain all the rights, powers, privileges and duties of the Issuing Lender hereunder with respect
to all Letters of Credit outstanding as of the effective date of its resignation as Issuing Lender
and all Reimbursement Obligations with respect thereto (including the right to require the Lenders
to make Base Rate Loans or fund risk participations in Unreimbursed Amounts

- 90 -

 

pursuant to Section 2.4(c)). If Bank of America resigns as Swing Loan Lender, it shall retain
all the rights of Swing Loan Lender provided for hereunder with respect to Swing Loans made by it
and outstanding as of the effective date of such resignation, including the right to require the
Lenders to make Base Rate Loans or fund risk participations in Swing Loans pursuant to Section
2.6(d). Upon the appointment of a successor Issuing Lender and/or Swing Loan Lender, (a) such
successor shall succeed to and become vested with all of the rights, powers, privileges and duties
of the retiring Issuing Lender or Swing Loan Lender, as the case may be, and (b) the successor
Issuing Lender shall issue letters of credit in substitution for the Letters of Credit, if any,
outstanding at the time of such succession or make other arrangements satisfactory to Bank of
America to effectively assume the obligations of Bank of America with respect to such Letters of
Credit.

     11.5 Survival. All covenants, agreements, representations and warranties made by the Credit
Parties and their Subsidiaries herein and in the other Loan Documents, and in the certificates or
other instruments delivered in connection with or pursuant to this Agreement and the other Loan
Documents, shall be considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the other Loan Documents and the making of
any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such
other party or on its behalf and notwithstanding that the Agent, the Issuing Lender or any Lender
may have had notice or knowledge of any Default or incorrect representation or warranty at the time
any credit is extended hereunder, and shall continue in full force and effect so long as the
principal of or any accrued interest on any Loan or any fee or any other Obligation payable under
this Agreement or the other Loan Documents is outstanding and unpaid or any Letter of Credit is
outstanding and so long as the Commitments have not expired or terminated. The provisions of
Sections 2.11, 2.12, and 10.3 and subsection 2.3(g) shall survive and remain in full force and
effect regardless of the consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the Commitments or the
termination of this Agreement or any other Loan Document or any provision hereof or thereof.

     11.6 Counterparts; Integration; References to Agreement; Effectiveness. This Agreement may be
executed in counterparts (and by different parties hereto on different counterparts), each of which
shall constitute an original, but all of which when taken together shall constitute a single
contract. This Agreement and any separate letter agreements with respect to fees payable to the
Agent or its counsel constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Whenever there is a reference in any Loan Document or UCC
Financing Statement to the “Credit Agreement” to which the Agent, the Lenders and the Credit
Parties are parties, such reference shall be deemed to be made to this Agreement among the parties
hereto. Except as provided in Section 6.1, this Agreement shall become effective when it shall
have been executed by the Agent and when the Agent shall have received counterparts hereof which,
when taken together, bear the signatures of each of the other parties hereto, and thereafter shall
be binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy
shall be effective as delivery of a manually executed counterpart of this Agreement.

     11.7 Severability. Any provision of this Agreement held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

     11.8 Right of Setoff. Each Credit Party hereby grants to the Agent, and each Lender that from
time to time maintains any deposit accounts, holds any funds or otherwise becomes indebted to the
Credit

- 91 -

 

Parties a security interest in all deposits (general or special, time or demand, provisional
or final) and funds at any time held and other indebtedness at any time owing by the Agent, or any
Lender to or for the credit or the account of any Credit Party as security for the Obligations, and
the Credit Parties hereby agree that the Agent, and each Lender are hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) or other funds at any time held
and other indebtedness at any time owing by the Agent, or such Lender to or for the credit or the
account of any Credit Party against any and all of the Obligations, irrespective of whether or not
the Agent or the Lenders shall have made any demand under this Agreement and although any of the
Obligations may be unmatured. The rights of the Agent and each Lender under this Section 11.8 are
in addition to any other rights and remedies (including other rights of setoff) which the Agent or
any such Lender may have.

     11.9 Subordination by Credit Parties. The Credit Parties hereby agree that all present and
future Indebtedness of any Credit Party to another Credit Party (“Intercompany
Indebtedness”) shall be subordinate and junior in right of payment and priority to the
Obligations, and each Credit Party agrees not to make, demand, accept or receive any payment in
respect of any present or future Intercompany Indebtedness, including, without limitation, any
payment received through the exercise of any right of setoff, counterclaim or cross claim, or any
collateral therefor, unless and until such time as the Obligations shall have been indefeasibly
paid in full; provided that, so long as no Default shall have occurred and be continuing
and no Default shall be caused thereby, the Credit Parties may make and receive such payments as
shall be customary in the ordinary course of the Credit Parties’ business. Without in any way
limiting the foregoing, in the event of any insolvency or bankruptcy proceedings, or any
receivership, liquidation, reorganization, dissolution or other similar proceedings relative to any
Credit Party or to its businesses, properties or assets, the Lenders shall be entitled to receive
payment in full of all of the Obligations before any Credit Party shall be entitled to receive any
payment in respect of any present or future Intercompany Indebtedness.

SCHEDULE
A

BANK OF AMERICA

Bank of America, N.A.
 

This agreement is made as of this 19 day of October, 2007, by and between each of the
undersigned customers (individually and collectively the “Customer”) and each of the undersigned
banks which maintain a bank account with the Customer (individually and collectively the “Bank”).

Customer has requested that Bank provide to Customer the services constituting the Bank
“AutoBorrow” program. For and in consideration of the promises contained herein and the performance
of obligations specified herein, it is agreed as fellows:

Definitions.

As used herein, the following terms shall have the meaning defined below:

	1.	 	Account: Customer’s Bank demand deposit account number 4602281935 or Customer’s substitute
or replacement demand deposit account if actually linked to the Line of Credit under the
AutoBorrow arrangement established under this Agreement.
	 
	2.	 	Borrowing Increment Amount: Specified whole dollar amount in which advances of funds shall be
made from the Line of Credit to the Account. For purposes of this Agreement, the Borrowing
Increment Amount shall be $1.00
	 
	3.	 	Borrowing Target: The minimum amount of collected funds Customer wishes to maintain in
Account; any balance less than the Borrowing Target shall trigger an incremental advance from
the Line of Credit if sufficient credit is available, as provided in Step 3, below under
“Operation of AutoBorrow.” For the purposes of this Agreement, the Borrowing Target shall be
$0.00.
	 
	4.	 	Line of Credit: Line of credit extended to Customer by Bank in the maximum principal amount
of $15,000,000.00, as evidenced by a Note dated December 29, 2004, or any lesser amount
established under the terms of the borrowing base set forth in the Loan Agreement between the
Bank and the Customer dated December 29, 2004, as those documents may be modified, amended,
extended or renewed. The term shall also include any line of credit replacing the Line of
Credit if the replacement is actually linked to the Account under the AutoBorrow arrangement
established under this Agreement.
	 
	5.	 	Repaying Increment Amount: Specified whole dollar amount in which funds transfers shall be
made from the Account to the Line of Credit. For purposes of this Agreement, the Repaying
Increment Amount shall be $1.00.
	 
	6.	 	Repaying Target: The maximum amount of collected funds Customer wishes to maintain in
Account; any whole dollar incremental balance in excess of the Repaying Target shall be
transferred from the account to pay down the Line of Credit if there exists an outstanding
principal balance on the Line of Credit, as provided in Step 2, below under “ Operation of
AutoBorrow.” For purposes of this Agreement, the Repaying Target shall be $0.00.

Operation of AutoBorrow.

	 	Step 1.	 	At the end of each banking day, Bank will determine the collected balance in the
Account and the outstanding Line of Credit principal balance.
	 
	 	Step 2.	 	If the collected funds in the Account are in excess of the Repaying Target by an
amount at least equal to the Repaying Increment Amount, Bank shall transfer funds in excess
of the Repaying Target amount from the Account in multiples of the Repaying Increment
Amount up to the amount necessary to pay off the Line of Credit principal balance.
Notwithstanding the foregoing, if the amount necessary to pay off the Line of Credit
principal balance is leas than the Repaying Increment Amount, Bank shall transfer only from
the account the whole dollar amount necessary to pay off the outstanding Line of Credit
principal balance.
	 
	 	Step 3.	 	If the collected balance in the Account is less than the Borrowing Target and funds
are available under the Line of Credit, Bank shall advance funds from the Line of Credit to
the Account in multiples of the Borrowing Increment Amount in order to bring the Account
balance up to the Borrowing Target. Notwithstanding the foregoing, if the amount available
in the Line of Credit is less than the Borrowing Increment Amount, Bank shall advance
available funds, in any whole dollar amount, to the Account.

 

 

Confirmations and Statements.

After each funds transfer, Bank will provide to Customer a written confirmation noting the date and
amount of each transfer. Customer will also receive a monthly AutoBorrow statement reflecting
activity in the Account.

Set Off

Bank is hereby authorized at any time to set off and charge against any deposit account of
Customer, as well as any money, instruments, securities, documents, chattel paper, credits, claims,
demands, income and any other property, rights and interests of any Customer which at any time
shall come into the possession or custody or under the control of Bank or any of its agents,
affiliates or correspondents, without notice or demand, any and all obligations due under any
document evidencing or securing the Line of Credit.

Related Documents.

This Agreement incorporates by reference each term, condition, representation, and warranty
contained in the documents evidencing and securing the Line of Credit including, but not limited
to, the Loan Agreement, Note, Borrowing Resolutions, Collateral Pledge Agreement, Security
Agreement and other pledges of collateral, and each term, condition, representation, and warranty
contained in the Depositor’s Agreement, Signature Cards and Corporate Resolutions relating to the
Account. To the extent that any such document conflicts with this Agreement, such document
controls.

Term and Termination.

This Agreement shall terminate immediately upon expiration or termination of the Line of Credit.
Otherwise, termination by Bank shall be effective 30 days after written notice is either hand
delivered or sent via certified mail to the Customer’s address set forth below. Unless terminated
by Bank, this Agreement shall remain in effect until Bank receives written notice of termination
from Customer and has been afforded a reasonable opportunity to act on such notice. This Agreement
may not be assigned by Customer.

Fees.

Customer agrees to compensate Bank for providing the AutoBorrow services in accordance with the
Bank rate schedule, which is subject to change from time to time.

Interest on Account.

Customer authorizes Bank of America, N.A., to debit the Account to pay any interest accrued and
owing on the Line of Credit.

Limitation of Liability.

Bank shall not be liable to Customer for failure to perform as contemplated or required by this
Agreement unless such failure is the result of the gross negligence or willful misconduct of Bank,
its employees, or agents. Bank shall not be liable under any circumstances to Customer or any third
party for any failure to perform if the failure is due to conditions beyond the control of Bank,
including, but not limited to, strikes, riots, war, military or national emergencies, acts of God,
natural disasters, fire, outages of computers or associated equipment, or failure of transportation
or communication methods or power supplies. In no event shall Bank be liable for special, indirect,
or consequential damages, even if advised of the possibility of such damages.

Arbitration.

Any controversy or claim between or among the parties hereto including but not limited to those
arising out of or relating to this instrument, agreement or document or any related instruments,
agreements or documents, including any claim based on or arising from an alleged tort, shall be
determined by binding arbitration in accordance with the Federal Arbitration Act (or if not
applicable, the applicable state law), the rules 01 practice and procedure for the arbitration of
commercial disputes of J.A.M.S./Endispute or any successor thereof (“J.A.M.S.”), and the “special
rules” set forth below. In the event of any inconsistency, the “special rules” shall control.
Judgment upon any arbitration award may be entered in any court having jurisdiction. Any party to
this instrument, agreement, or document may bring an action, including a summary or expedited
proceeding, to compel arbitration of any controversy or claim to which this agreement applies in
any court having jurisdiction over such action.

 

 

(i)Special Rules. The arbitration shall be conducted in the county of any borrower’s domicile at
time of the execution of this instrument, agreement or document and administered by J.A.M.S. who
will appoint an arbitrator; if J.A.M.S. is unable or legally precluded from administering the
arbitration, then the American Arbitration Association will serve. All arbitration hearing will be
commenced within 90 days of the demand for arbitration; further, the arbitrator shall only, upon a
showing of cause, be permitted to extend the commencement of such hearing for up to an additional
60 days.

(ii)Reservation of Rights. Nothing in this arbitration provision shall be deemed to (1) limit the
applicability of any otherwise applicable statutes of limitation or repose and any waivers
contained in this instrument, agreement, or document; or (iii) be a waiver by the Bank of the
protection afforded to it by 12 U.S.C. Sec. 91 or any substantially equivalent state law; or (iii)
limit the right of the Bank hereto (a) to exercise self help remedies such as (but not limited to)
setoff, or (b) to foreclose against any real or personal property collateral, or(c) to obtain from
a court provisional or ancillary remedies such as (but not limited to) injunctive relief, writ of
possession or the appointment of a receiver. The Bank may exercise such self help rights, foreclose
upon such property, or obtain such provisional or ancillary remedies before, during or after the
pendency of any arbitration proceeding brought pursuant to this instrument, agreement or document.
Neither this exercise of self help remedies nor the institution or maintenance of an action for
foreclosure or provisional or ancillary remedies shall constitute a waiver of the right of any
party, including the claimant in any such action, to arbitrate the merits of the controversy or
claim occasioning resort to such remedies.

Amendments.

This Agreement constitutes the complete understanding of Customer and Bank as to the AutoBorrow
services, and specifically excludes all previous written or oral representations. No amendments to

	Re:	 	Amended and Restated Credit and Security Agreement,

Ladies & Gentlemen:

     Pursuant to the above-referenced Credit Agreement, enclosed are copies of consolidated and
consolidating financial statements of the Core Ameresco Companies for the fiscal [quarter] [year]
ended               
       (the “Fiscal Period”), prepared in accordance with GAAP. Capitalized terms used
but not defined herein shall have the meanings set forth in the Credit Agreement.

     As required, a review of the activities of the Credit Parties during the Fiscal Period has
been made under the supervision of the undersigned with a view to determining whether, during the
Fiscal Period, the Credit Parties have kept, observed, performed and fulfilled each and every
covenant and condition of the Credit Agreement. To the best of my knowledge and belief there
neither exists on the date of this certificate, nor existed during the Fiscal Period, any Default
or Event of Default, except as set forth on any attachment hereto. There has been no change in
GAAP since the date of the last audited financial statements delivered to you by the Borrower which
has or could have an effect on the financial statements accompanying such certificate, except such
changes as are set forth on any attachment hereto.

     As further required, attached are covenant calculations showing compliance by the Core
Ameresco Companies with the financial covenants set forth in Section 8.10 of the Credit Agreement.

	 	 	 	 	 
	 	Very truly yours,

partnership interests, limited liability company interests and shares of capital stock, as
applicable, of the Listed Companies as listed on Schedule I attached hereto (the
“Pledged Equity”) (together with the appropriate powers duly endorsed in blank), and, to
the extent such collateral is not certificated, the appropriate assignment and control documents,
and (b) the promissory notes payable to the Pledgors as listed in Schedule II attached
hereto (the “Pledged Notes”, and together with the Pledged Equity and any additional
investment property, securities, securities entitlements, or collateral pledged hereunder, the
“Pledged Collateral”), and each Pledgor hereby grants to the Administrative Agent for
itself and for the benefit of the other Secured Parties a security interest in all of the Pledged
Collateral as security for the due and punctual payment and performance of the Secured Obligations
described in Section 3 hereof.

     3. Secured Obligations. The security interest hereby granted shall secure the due and
punctual payment and performance of the following liabilities and obligations of the Pledgors
(herein called the “Secured Obligations”):

          (a) Principal of and premium, if any, and interest on the Loans; and

          (b) Any and all other obligations and indebtedness of any of the Credit Parties to the Secured
Parties or any of them, whether direct or indirect, absolute or contingent, due or to become due or
now existing or hereafter arising or incurred under the Credit Agreement, any other Loan Document
or under any Hedging Agreement permitted by the Credit Agreement, all as amended from time to time
including, without limitation, any and all Reimbursement Obligations, any and all other fees,
premiums and penalties.

     4. Special Warranties and Covenants of the Pledgors. Each Pledgor hereby warrants and
covenants to the Secured Parties with respect to the Pledged Collateral for which it is the
“Pledgor,” as set forth on Schedules I and II, that:

          (a) The Pledged Collateral is duly and validly pledged with the Administrative Agent for the
benefit of the Secured Parties in accordance with law, the Administrative Agent for the benefit of
the Secured Parties has a First Priority security interest in such Pledged Collateral, and each
Pledgor warrants and will defend the Secured Parties’ right, title and security interest in and to
the Pledged Collateral against the claims and demands of all Persons whomsoever.

          (b) Each Pledgor has good title to the Pledged Collateral, free and clear of all Liens, except
as expressly set forth in or permitted under the Credit Agreement.

          (c) All of the Pledged Equity has been duly and validly issued and is fully paid and
nonassessable.

          (d) The Pledged Equity constitutes the amount and percentage of partnership interests, limited
liability company interests or shares, as applicable, of the presently issued and

2

 

outstanding partnership interests, limited liability company interests or capital stock of the
Listed Companies, as applicable, as set forth on Schedule I.

          (e) If any additional partnership interests, limited liability company interests or shares of
capital stock of any class of the Listed Companies or if any promissory notes of the Listed
Companies or other securities of the Listed Companies are acquired by any Pledgor after the date
hereof, the same shall constitute Pledged Collateral and shall be deposited with and pledged to the
Administrative Agent for itself and for the benefit of the other Secured Parties as provided in
Section 2 hereof simultaneously with such acquisition. The Pledgors will promptly notify the
Administrative Agent of the date and amount of any loans made from time to time by the Pledgors to
the Listed Companies as permitted by the Credit Agreement.

          (f) No Pledgor will sell, convey or otherwise dispose of any of the Pledged Collateral, nor
will any Pledgor create, incur or permit to exist any Lien with respect to any of the Pledged
Collateral or the proceeds thereof, other than Liens with respect to the Pledged Collateral created
hereby or Liens which are otherwise permitted under the Loan Documents and except as permitted by
the Credit Agreement.

          (g) If any additional partnership interests, limited liability company interests or shares of
capital stock of any class of the Listed Companies are issued, any such partnership interests,
limited liability company interests or additional shares of capital stock shall be deposited with
and pledged to the Administrative Agent for itself and for the benefit of the other Secured Parties
simultaneously with such issuance as provided in Section 2 hereof.

          (h) The Pledged Notes evidence the amount of outstanding indebtedness for money borrowed of
the respective issuers thereof indicated on Schedule II hereto.

          (i) If any additional promissory notes are acquired by any Pledgor from the issuers of the
Pledged Notes or any other Person, the same shall constitute Pledged Notes and Pledged Collateral
and shall be deposited with and pledged to the Administrative Agent for itself and the benefit of
the other Secured Parties as provided in Section 2 hereof simultaneously with such acquisition.
Upon the request of the Administrative Agent, the Pledgors will promptly notify the Administrative
Agent of any loans made from time to time to such issuers as permitted by the Credit Agreement.

     5. Distributions. In case, upon the dissolution, winding up, liquidation or
reorganization of the Listed Companies whether in bankruptcy, insolvency or receivership
proceedings or upon an assignment for the benefit of creditors or any other marshaling of the
assets and liabilities of the Listed Companies or otherwise, any sum shall be paid or any property
shall be distributed upon or with respect to any of the Pledged Collateral, such sum shall be paid
over to the Administrative Agent for the benefit of the Secured Parties as collateral security for
the Secured Obligations. In case any stock dividend shall be declared on any of the Pledged
Collateral, or any share of stock or fraction thereof shall be issued pursuant to any stock split
involving any of the Pledged Collateral, or, any distribution of capital or profits shall be made
on any of the Pledged Collateral, or any property shall be distributed upon or with respect to the
Pledged Collateral, the limited partnership interests, limited liability company interests, shares,

3

 

cash or other property so distributed shall be delivered to the Administrative Agent to be
held for the benefit of the Secured Parties as collateral security for the Secured Obligations.

     6. Events of Default. The Pledgors shall be in default under this Agreement upon the
happening of any Event of Default, as defined in the Credit Agreement (herein called an “Event
of Default”).

     7. Rights and Remedies of Secured Parties. Upon the occurrence and during the
continuance of any Event of Default, the Secured Parties shall have the following rights and
remedies:

          (a) All rights and remedies provided by law, including, without limitation, those provided by
the Uniform Commercial Code;

          (b) All rights and remedies provided in this Agreement; and

          (c) All rights and remedies provided in the Credit Agreement or in the Loan Documents, or in
any other agreement, document or instrument pertaining to the Secured Obligations.

     8. Right to Transfer into Name of Administrative Agent, etc. Upon the occurrence and
during the continuance of an Event of Default, but subject to the provisions of the Uniform
Commercial Code or other applicable law, with 10 days prior written notice to the Pledgors, the
Administrative Agent may cause all or any of the Pledged Collateral to be transferred into its name
or into the name of its nominee or nominees (such transfer, a “Transfer”). So long as no
Event of Default shall have occurred and be continuing, each Pledgor shall be entitled to exercise
as such Pledgor shall deem fit, but in a manner not inconsistent with the terms hereof or of the
Secured Obligations, the voting power with respect to the Pledged Collateral.

     9. Right of Administrative Agent to Exercise Voting Power, etc. Upon the occurrence
and during the continuance of an Event of Default and following a Transfer, the Administrative
Agent for the benefit of the Secured Parties shall be entitled to exercise the voting power with
respect to the Pledged Collateral, to receive and retain, as collateral security for the Secured
Obligations, any and all dividends or other distributions at any time and from time to time
declared or made upon any of the Pledged Collateral, and to exercise any and all rights of payment,
conversion, exchange, subscription or any other rights, privileges or options pertaining to the
Pledged Collateral as if it were the absolute owner thereof, including, without limitation, the
right to exchange, at its discretion, any and all of the Pledged Collateral upon the merger,
consolidation, reorganization, recapitalization or other readjustment of the Listed Companies or,
upon the exercise of any such right, privilege or option pertaining to the Pledged Collateral, and
in connection therewith, to deposit and deliver any and all of the Pledged Collateral with any
committee, depositary, transfer agent, registrar or other designated agency upon such terms and
conditions as the Administrative Agent may determine, all without liability except to account for
property actually received, but the Administrative Agent shall have no duty to exercise any of the
aforesaid rights, privileges or options and shall not be responsible for any failure to do so or
delay in so doing.

4

 

     10. Right of Administrative Agent to Dispose of Collateral, etc. Upon the occurrence
and during the continuance of an Event of Default, the Administrative Agent shall have the right at
any time or times thereafter to sell, resell, assign and deliver all or any of the Pledged
Collateral in one or more parcels at any exchange or broker’s board or at public or private sale.
Unless the Pledged Collateral is perishable or threatens to decline speedily in value or is of a
type customarily sold on a recognized market, the Administrative Agent will give the Pledgors at
least ten (10) days’ prior written notice in accordance with Section 20 hereof of the time and
place of any public sale thereof or of the time after which any private sale or any other intended
disposition of any of the Pledged Collateral is to be made. Any such notice shall be deemed to
meet any requirement hereunder or under any applicable law (including the Uniform Commercial Code)
that reasonable notification be given of the time and place of such sale or other disposition.
Such notice may be given without any demand of performance or other demand, all such demands being
hereby expressly waived by each Pledgor. All such sales shall be at commercially reasonable price
or prices and either for cash or on credit or for future delivery (without assuming any
responsibility for credit risk). At any such sale or sales, to the extent permitted by law, any
Secured Party may purchase any or all of the Pledged Collateral to be sold thereat upon such terms
as the Administrative Agent may deem best. Upon any such sale or sales the Pledged Collateral so
purchased shall be held by the purchaser absolutely free from any claims or rights of whatsoever
kind or nature, including any equity of redemption and any similar rights, all such equity of
redemption and any similar rights being hereby expressly waived and released by each Pledgor. In
the event any consent, approval or authorization of any governmental agency will be necessary to
effectuate any such sale or sales, each Pledgor shall execute, and hereby agrees to cause the
Listed Companies to execute, all such applications or other instruments as may be required.

     Each Pledgor recognizes that the Administrative Agent may be unable to effect a public sale of
all or a part of the Pledged Collateral by reason of certain prohibitions contained in the
Securities Act of 1933, as amended (the “Securities Act”) or otherwise but may be compelled
to resort to one or more private sales to a restricted group of purchasers, each of whom will be
obligated to agree, among other things, to acquire such Pledged Collateral for its own account, for
investment and not with a view to the distribution or resale thereof. Each Pledgor acknowledges
that private sales so made may be at prices and upon other terms less favorable to the seller than
if such Pledged Collateral were sold at public sales without such restrictions, and that the
Administrative Agent has no obligation to delay sale of any such Pledged Collateral for the period
of time necessary to permit such Pledged Collateral to be registered for public sale under the
Securities Act. Each Pledgor agrees that any such private sales shall not be deemed to have been
made in a commercially unreasonable manner solely because they shall have been made under the
foregoing circumstances.

     11. Collection of Amounts Payable on Account of Pledged Collateral, etc. Upon the
occurrence and during the continuance of any Event of Default, the Administrative Agent may, but
without obligation to do so, demand, sue for and/or collect any money or property at any time due,
payable or receivable, to which it may be entitled hereunder, on account of, or in exchange for,
any of the Pledged Collateral and shall have the right, for and in the name, place and stead of
each Pledgor, to execute endorsements, assignments or other instruments of conveyance or transfer
with respect to all or any of the Pledged Collateral.

5

 

     12. Care of Pledged Collateral in Administrative Agent’s Possession. Beyond the
exercise of reasonable care to assure the safe custody of the Pledged Collateral while held
hereunder, the Administrative Agent shall have no duty or liability to collect any sums due in
respect thereof or to protect or preserve rights pertaining thereto, and shall be relieved of all
responsibility for the Pledged Collateral upon surrendering the same to the Pledgors.

     13. Proceeds of Collateral. By way of enlargement and not by way of limitation of the
rights of the Administrative Agent under applicable law or the Credit Agreement or Loan Documents,
the Administrative Agent shall receive and apply the proceeds of any sale or sales of the Pledged
Collateral, together with any other additional collateral security at the time received and held
hereunder, to the Secured Obligations (including, without limitation, the Loans) in accordance with
the terms of the Credit Agreement. In the event the proceeds of any sale, lease or other
disposition of the Pledged Collateral hereunder are insufficient to pay all of the Secured
Obligations in full, each Pledgor will be liable for the deficiency, together with interest thereon
at the maximum rate provided in the Credit Agreement, and the cost and expenses of collection of
such deficiency, including (to the extent permitted by law), without limitation, reasonable
attorneys’ fees, expenses and disbursements.

     14. Credit Agreement. Notwithstanding any other provision of this Agreement, the
rights of the parties hereunder are subject to the provisions of the Credit Agreement, including
the provisions thereof pertaining to the rights and responsibilities of the Administrative Agent.
In the event that any provision of this Agreement is in conflict with the terms of the Credit
Agreement, the Credit Agreement shall control. Unless the context shall otherwise clearly
indicate, the terms “Secured Party” and “Secured Parties” as used herein shall be deemed to include
the Administrative Agent acting on behalf of the Secured Parties pursuant to the Credit Agreement.
The term “Administrative Agent” as used herein shall include Bank of America, N.A., or any other
Person acting as Administrative Agent for the Secured Parties pursuant to the terms of the Credit
Agreement.

     15. Waivers, etc. Each Pledgor hereby waives presentment, demand, notice, protest
and, except as is otherwise provided herein, all other demands and notices in connection with this
Agreement or the enforcement of the Secured Parties’ rights hereunder or in connection with any
Secured Obligations or any Pledged Collateral; consents to and waives notice of the granting of
renewals, extensions of time for payment or other indulgences to the other Listed Companies or the
other Pledgors or to any third party, or substitution, release or surrender of any collateral
security for any Secured Obligation, the addition or release of Persons primarily or secondarily
liable on any Secured Obligation or on any collateral security for any Secured Obligation, the
acceptance of partial payments on any Secured Obligation or on any collateral security for any
Secured Obligation and/or the settlement or compromise thereof. No delay or omission on the part
of the Secured Parties in exercising any right hereunder shall operate as a waiver of such right or
of any other right hereunder. Any waiver of any such right on any one occasion shall not be
construed as a bar to or waiver of any such right on any future occasion. Each Pledgor further
waives any right it may have under the laws of The Commonwealth of Massachusetts, under the laws of
any state in which any of the Pledged Collateral may be located or which may govern the Pledged
Collateral, or under the laws of the United States of America, to notice (other than any
requirement of notice provided herein or in any other Loan Documents) or to a judicial hearing

6

 

prior to the exercise of any right or remedy provided by this Agreement to the Administrative
Agent or the Secured Parties and waives its rights, if any, to set aside or invalidate any sale
duly consummated in accordance with the foregoing provisions hereof on the grounds (if such be the
case) that the sale was consummated without a prior judicial hearing. Each Pledgor’s waivers under
this Section have been made voluntarily, intelligently and knowingly and after such Pledgor has
been apprized and counseled by its attorneys as to the nature thereof and its possible alternative
rights.

     16. Termination; Assignment, etc. When all the Secured Obligations have been paid in
full and have been terminated and the Commitments of the Lenders to make any Loan under the Credit
Agreement have terminated or expired and no Letters of Credit remain outstanding, this Agreement
and the security interest in the Pledged Collateral created hereby shall terminate. No waiver by
the Administrative Agent or by any other holder of Secured Obligations of any default shall be
effective unless in writing nor operate as a waiver of any other default or of the same default on
a future occasion. In the event of a sale or assignment by any Secured Party of all or any of the
Secured Obligations held by it, any Secured Party may assign or transfer its rights and interest
under this Agreement in whole or in part to the purchaser or purchasers of such Secured
Obligations, whereupon such purchaser or purchasers shall become vested with all of the powers and
rights of a Secured Party hereunder.

     17. Reinstatement. Notwithstanding the provisions of Section 16, this Agreement shall
continue to be effective or be reinstated, as the case may be, if at any time any amount received
by any Secured Party in respect of the Secured Obligations is rescinded or must otherwise be
restored or returned by any such Secured Party upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of any of the Listed Companies, any Pledgor or upon the appointment
of any intervener or conservator of, or trustee or similar official for, the Listed Companies or
any Pledgor, or any substantial part of their respective properties, or otherwise, all as though
such payments had not been made.

     18. Governmental Approvals, etc. Upon the exercise by the Administrative Agent of any
power, right, privilege or remedy pursuant to this Agreement which requires any consent, approval,
qualification or authorization of any governmental authority or instrumentality, each Pledgor will
execute and deliver, or will cause the execution and delivery of, all applications, certificates,
instruments and other documents and papers that the Administrative Agent or any Secured Party may
be required to obtain for such governmental consent, approval, qualification or authorization.

     19. Restrictions on Transfer, etc. To the extent that any restrictions imposed by the
charter, certificate of limited partnership, limited partnership agreement, operating agreement or
by-laws of any of the Listed Companies or any other document or instrument would in any way affect
or impair the pledge of the Pledged Collateral hereunder or the exercise by the Administrative
Agent of any right granted hereunder, including, without limitation, the right of the
Administrative Agent to dispose of the Pledged Collateral upon the occurrence and during the
continuance of any Event of Default, each Pledgor hereby waives such restrictions to the extent
permitted by applicable securities laws, and represents and warrants that it has caused the Listed
Companies to take all necessary action to waive such restrictions, and each Pledgor

7

 

hereby agrees that it will take any further action which the Administrative Agent may
reasonably request in order that the Administrative Agent may obtain and enjoy the full rights and
benefits granted to the Administrative Agent by this Agreement free of any such restrictions.

     20. Notices. All notices, consents, approvals, elections and other communications
hereunder shall be in writing (whether or not the other provisions of this Agreement expressly so
provide) and shall be deemed to have been duly given if delivered in accordance with the terms of
the Credit Agreement.

     21. Miscellaneous. This Agreement shall inure to the benefit of and be binding upon
the Administrative Agent, the Secured Parties and each Pledgor and their respective successors and
assigns, and the term “Secured Parties” shall be deemed to include any other holder or holders of
any of the Secured Obligations. In case any provision in this Agreement shall be invalid, illegal
or unenforceable, the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each of which shall be
an original, but all of which together shall constitute one instrument.

     22. Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement, including the
validity hereof and the rights and obligations of the parties hereunder, shall be construed in
accordance with and governed by the laws of The Commonwealth of Massachusetts. Each Pledgor, to
the extent that it may lawfully do so, hereby consents to service of process, and to be sued, in
any state or federal court located in The Commonwealth of Massachusetts, as well as to the
jurisdiction of all courts to which an appeal may be taken from such courts, for the purpose of any
suit, action or other proceeding arising out of any of its obligations hereunder or with respect to
the transactions contemplated hereby, and expressly waives any and all objections it may have as to
venue in any such courts. Each Pledgor further agrees that a summons and complaint commencing an
action or proceeding in any of such courts shall be properly served and shall confer personal
jurisdiction if served personally or by certified mail to it in accordance with Section 20 hereof
or as otherwise provided under the laws of The Commonwealth of Massachusetts. Nothing in this
Agreement shall affect any right the Administrative Agent or any Secured Party may otherwise have
to bring an action or proceeding relating to this Agreement against any Pledgor or its properties
in the courts of any jurisdiction. EACH PLEDGOR IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN
ANY SUIT, ACTION OR OTHER PROCEEDING INSTITUTED BY OR AGAINST SUCH PLEDGOR IN RESPECT OF ITS
OBLIGATIONS HEREUNDER OR THE TRANSACTIONS CONTEMPLATED HEREBY.

and collectively the “Delaware or Massachusetts Parties”), the Lenders from time to time party
thereto (the “Lenders”), and Bank of America, N.A., as administrative agent for the Lenders (the
“Administrative Agent”). Except as otherwise defined herein, terms defined in the Credit Agreement
are used herein as therein defined.

     We have acted as special counsel for the Credit Parties in connection with the Credit
Agreement and the other Loan Documents, as defined below, and the documents and agreements
delivered pursuant to the Loan Documents at the Effective Time. We note that prior to the
negotiation of the transactions contemplated by the Prior Credit Agreement we did not act as

 

 

counsel to the Credit Parties with respect to any matters. We also note that we do not act as
general counsel to the Borrower or any of its subsidiaries. The Borrower and its subsidiaries (a)
have in-house counsel and (b) regularly retain the services of various outside counsel.
Accordingly, our knowledge of the business and affairs of the Credit Parties is necessarily
limited.

     In connection with this opinion, we have reviewed the following documents:

	 	(1)	 	the Credit Agreement;
	 
	 	(2)	 	the Revolving Credit Notes issued by the Borrower as of the date hereof;
	 
	 	(3)	 	the Swing Loan Note;
	 
	 	(4)	 	the Pledge Agreement;
	 
	 	(5)	 	the Subordination Agreement;
	 
	 	(6)	 	the Uniform Commercial Code (“UCC”) Financing Statements copies of which are
attached hereto as Exhibit A (the “UCC Financing Statements”);
	 
	 	(7)	 	the Perfection Certificates completed and executed by the Borrower and each
Guarantor;
	 
	 	(8)	 	the Certificate of Incorporation, Certificate of Formation, bylaws, operating
agreements, and other organizational documents of the Borrower and each of the
Guarantors; and
	 
	 	(9)	 	the Certificate of good standing for the Borrower and each of the Guarantors.

     The documents in clauses (1) through (5) are sometimes collectively referred to herein as the
“Loan Documents” and each individually as a “Loan Document”. The UCC Financing Statements include
those financing statements filed in connection with the Prior Credit Agreement. The documents in
clause (8) and (9) are collectively referred to herein as the “Organizational Documents”. We
express no opinion as to any of the agreements, documents or instruments referred to herein other
than the Loan Documents, UCC Financing Statements, and Organizational Documents, and our opinion in
paragraphs 1 and 2 below concerning the legal existence and good standing of the Borrower and each
of the Delaware or Massachusetts Parties is based solely on such certificates and is given as of
the date of such certificates.

     In addition to the foregoing, we have examined (a) the original or certified, conformed or
photostatic copies for the Borrower and each Guarantor of their (i) Organizational Documents, as
amended to date, (ii) its bylaws or limited liability company operating agreement, as applicable,
as amended to date, and (iii) records of all corporate proceedings relating to the Loans; (b) the
certificate of officers’ of the Credit Parties attached hereto as Exhibit B (the “Officers’
Certificate”); and (c) such other documents, records, certificates and legal matters as we have
deemed necessary or relevant for purposes of issuing the opinions hereinafter expressed. We

2

 

have also examined the Uniform Commercial Code as enacted and in effect in The Commonwealth of
Massachusetts on the date hereof (“MA UCC”).

     In our examination we have also assumed the genuiness of all signatures (other than those on
behalf of the Borrower and the Guarantors), the legal capacity of the natural Persons, the
authenticity of all documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photostatic copies, and the authenticity of the
originals of such copies. As to any facts material to this letter, we have relied solely upon (and
have assumed without investigating the accuracy or completeness of) written certificates,
statements and representations of officers and other representatives of the Borrower and the
Guarantors (including without limitation the representations and warranties contained in the Loan
Documents), and upon certificates of public officials.

     With respect to Chapter 271, §49 of the Massachusetts General Laws, we have assumed with your
permission that you and each Lender are subject to control, regulation or examination by one or
more state or federal regulatory agencies. Section 49 provides that it is unlawful to take or
receive in exchange for a loan recovery of interest and expenses which in the aggregate exceed 20%
per annum unless the lender shall have made the filing contemplated by §49 prior to making the loan
or is a “lender subject to control, regulation or examination by a state or federal regulatory
agency.”

     We have not made any independent review or investigation as to any factual matters in
connection with the issuance of the opinions contained herein (including, without limitation,
conducting any docket searches or other searches) and any limited inquiry undertaken by us during
the preparation of this opinion letter should not in any way be regarded as such investigation.
Whenever our opinion with respect to the existence of facts is indicated to be based upon our
knowledge or the like, we are referring to the actual knowledge of only those Choate, Hall &
Stewart LLP attorneys who were actively involved in our representation of the Borrower and the
Guarantors in connection with the transactions contemplated by the Loan Documents.

     Our opinions contained herein are subject to the qualifications (a) that validity and
enforceability may be subject to (i) bankruptcy, insolvency, reorganization, moratorium,
fraudulent transfer, fraudulent conveyance, equitable subordination or other similar laws or
doctrines now or hereafter in effect relating to creditors’ rights generally, (ii) general
principles of equity (regardless of whether considered at a proceeding in equity or at law),
including without limitation the principle that equitable remedies, such as the remedy of specific
performance, are subject to the discretion of the court before which any proceeding therefor may be
brought, (iii) statutory and decisional law concerning recourse by creditors to security in
absence of notice and hearing and (iv) duties and standards imposed on parties, including,
without limitation, the duties of good faith and fair dealing; (b) that we express no
opinion as to the validity or enforceability of (i) any provision contained in any of the
Loan Documents providing for rights of indemnity and/or contribution, (ii) any provision
contained in any of the Loan Documents purporting to waive (or having the effect of waiving) any
rights under the constitution or laws of the United States of America or any state or commonwealth,
or any provision purporting to waive any rights in connection with any bankruptcy or insolvency or
which is otherwise contrary to public policy, (iii) any choice of law provision in any of
the Loan

3

 

Documents, or any provision restricting access to legal or equitable remedies, (iv)
any provision which provides that any jurisdiction is the exclusive forum for any dispute,
(v) the rights and remedies purportedly granted to the Administrative Agent and Lenders in
Sections 4.4, 4.5 and 9.2 of the Credit Agreement, and any similar section in any other Loan
Document, or any consent to receivership or similar proceeding contained in Section 9.3 of the
Credit Agreement, and any similar section in any other Loan Document, (vi) any provision
providing that the failure to exercise any right, remedy or option under any Loan Document shall
not operate as a waiver thereof, or any provision providing that amendments, waivers or
modifications to any Loan Document must be in writing, (vii) any provision contained in any
Loan Documents providing for the release of, or having the effect of releasing, any Person
prospectively from any liability from its own wrongful or negligent acts or for breach of any
agreement, (viii) any powers of attorney purported to be granted in any of the Loan
Documents, (ix) any provision providing for the payment of interest on overdue installments
of interest, default interest or prepayment premiums or charges and (x) any provision
purporting to establish an evidentiary standard; and (c) certain portions of the Loan
Documents may be unenforceable in whole or in part, although the inclusion of such provisions
therein does not render the Loan Documents invalid, and the Loan Documents contain adequate
provisions for the practical realization of the principal rights and benefits purported to be
afforded thereby (subject to the other qualifications contained in this opinion and the economic
consequences of any delay that may arise from the unenforceability of any provision).

     In rendering this opinion, we have assumed that no party will exercise any right or remedy
except in an equitable and commercially reasonable manner and in good faith, and that each party to
any of the Loan Documents has received the agreed upon consideration, and, if a Loan Document does
not recite that it is executed as an instrument under the seal, that such consideration is legally
sufficient. We have also assumed that each party to the Loan Documents has all requisite power and
authority and has taken all necessary corporate or other action (including, without limitation,
obtaining all governmental approvals, authorizations and consents and making all necessary filings
with all applicable governmental entities required on its part) necessary to authorize, execute,
enter into and perform its obligations under each Loan Document to which it is a party and to
effect the respective transactions contemplated thereby, and that each such Loan Document
constitutes the legal, valid and binding obligation of each such other party and is enforceable
against each such other party in accordance with the respective terms thereof. We have also
assumed that all laws, rules, regulations and decisions applicable to this opinion are generally
available in terms of access and distribution following publication or other release and are in a
format which makes legal research reasonably feasible.

     The opinions expressed herein do not purport to cover, and we express no opinion with respect
to the applicability of, Section 548 of the United States Bankruptcy Code or any comparable
provision of state law. In addition, we express no opinion as to whether a subsidiary may
guarantee or otherwise become liable for, or pledge its assets to secure, indebtedness incurred by
its parent except to the extent such subsidiary may be determined to have benefited from the
incurrence of such indebtedness, or as to whether such benefit may be measured other than by the
extent to which the proceeds of such indebtedness are directly or indirectly made available to such
subsidiary for its corporate purposes.

4

 

     We have also assumed that for each Guarantor such Guarantor’s obligations under its Guarantee
and any Loan Documents to which it is a party are in furtherance of its corporate purposes and
necessary or convenient to the conduct, promotion or attainment of its business, that each such
Guarantor has obtained consideration that is fair and sufficient to support its Guarantee and any
Loan Document to which it is a party and that a court of competent jurisdiction would deem such
consideration to have been duly received by each such Guarantor.

     We express no opinion as to any of the agreements, documents or instruments referred to herein
other than the Loan Documents. We also express no opinion as to any matters that would be excluded
by Section 19 of the Legal Opinion Accord of the ABA Section of Business Law were it to govern this
letter unless such matter is expressly contained in this opinion. We also express no opinion as to
any matters that arise solely as a result of any laws, orders, rules, regulations or limitations
created or issued by any federal, state or municipal authority or any agency or subdivision
thereof, which regulates any portion of the Borrower’s or any Guarantors’ business. We direct your
attention to the fact that our opinions are limited in scope consistent with the Legal Opinion
Principles issued by the Committee on Legal Opinions of the American Bar Association’s Business Law
Section as published in 53 Business Lawyers 831 (May, 1998).

     With regard to the opinions expressed in paragraphs (1) and (2) below as to the valid
existence and good standing and as to the valid organization or incorporation, of the Borrower and
the Delaware or Massachusetts Parties as applicable, we have assumed the accuracy and completeness
of, and have relied solely upon, certificates of governmental officials, dated on or after May 26,
2008.

     We note that you are relying on the opinions of Kennedy Covington Lobdell & Hickman, L.L.P.
(with respect to matters of North Carolina law), Parsons Behle & Latimer (with respect to matters
of Nevada law), Frost Brown Todd LLC (with respect to matters of Kentucky and Tennessee law) and
Porter & Hedges LLP (with respect to matters of Texas law) (such opinions collectively referred to
as the “Local Counsel Opinions”) as to the due organization and existence of AmerescoSolutions,
Sierra Energy, E.Three, Enertech, Federal Solutions and Solar-Solutions (collectively, referred to
as the “Non-Delaware or Massachusetts Companies”), respectively, and the due authorization,
execution and delivery of the documents to be executed and delivered by the Non-Delaware or
Massachusetts Companies and to such other matters as set forth in the Local Counsel Opinions. We
express no opinion regarding the matters contained in the Local Counsel Opinions or to any choice
of laws applicable to the obligations of the Non-Delaware or Massachusetts Companies. We have
assumed herein the due authorization, execution and delivery of the Credit Agreement and other Loan
Documents by the Non-Delaware or Massachusetts Companies, that all actions have been taken by the
Non-Delaware or Massachusetts Companies which are necessary to creating a valid, legal and binding
obligation under applicable state law, that the Non-Delaware or Massachusetts Companies do not
violate any applicable state law or regulation by incurring the obligations contained in the Credit
Agreement and that the laws of The Commonwealth of Massachusetts (without giving effect to any
choice of laws provisions thereunder) apply to the obligations of the Non-Delaware or Massachusetts
Companies under the Credit Agreement and other Loan Documents.

     Our opinions herein are limited to the effect on the subject transactions of the internal laws
of the Commonwealth of Massachusetts (without giving affect to conflicts of laws

5

 

principles), the Delaware General Corporation Law, the Delaware Limited Liability Company Act
and the Uniform Commercial Code in effect on the date hereof in the State of Delaware (“DE UCC”),
in each case, in our experience, normally applicable to credit transactions of the type
contemplated by the Loan Documents. We express no opinion as to the applicability or effect of any
other laws. We render no opinion on matters except as specifically stated herein.

     In rendering our opinions set forth in paragraphs 8 and 9 below, we have assumed that no part
of the Collateral identified in the Loan Documents in respect of which provision is made in the
Loan Documents for a lien or security interest (other than the Non-Delaware or Massachusetts
Companies) consists of property subject to a United States statute or treaty providing for a
national or international recordation, registration, or certificate of title, or specifying a place
for filing different from that specified in Article 9 of the DE UCC or MA UCC. Without limiting
any other provisions contained in this opinion, our opinion in paragraph 10 below is rendered
solely to the extent that the MA UCC as in effect on the date hereof, is applicable to such matters
and we express no opinion as to such applicability.

     We have made no examination of, and express no opinion herein as to (i) the right, title or
interest of any Person to any of the property, tangible or intangible, that constitutes any of the
Collateral; (ii) the existence of any liens, security interests, charges or encumbrances (other
than those created by the Loan Documents) on the Collateral; (iii) the value of any security
granted to the Administrative Agent; (iv) the creation or enforceability of any security interest
other than in the Collateral; (v) the ranking or priority of any liens or security interests; (vi)
the perfection of any security interest in any collateral other than the Collateral; or (vii)
matters regarding the classification of property as real or Personal property. We have assumed
that the Collateral is in existence.

     We also call your attention to the following provisions of the DE UCC and the MA UCC:

	 	(i)	 	the effectiveness of DE UCC and MA UCC financing statements will lapse at a
statutorily defined time (generally five years after the date of filing) unless a
continuation statement is filed prior to such lapse in accordance with the DE UCC
or the MA UCC, as applicable;
	 
	 	(ii)	 	Section 9-507(c) of each of the DE UCC and MA UCC provides that, if a debtor
so changes its name that a filed financing statement becomes seriously misleading, the
filing is not effective to perfect a security interest in collateral acquired by such
debtor more than four months after the change unless an amendment to the financing
statement which renders the financing statement not seriously misleading is filed
within four months after the change;
	 
	 	(iii)	 	under certain circumstances described in Section 9-315 of each of the DE UCC
and MA UCC, the rights of a secured party to enforce a perfected security interest in
proceeds of collateral may be limited;
	 
	 	(iv)	 	continued perfection of security interest may require the filing of new
appropriate financing statements or of amendments to financing statements in the event
of a

6

 

	 	 	 	change of the name, location or legal identity of structure of the borrower or, in
certain cases, the location of the collateral;

	 	(v)	 	Section 552 of the United States Bankruptcy Code (11 U.S.C. § 552) limits the
extent to which property acquired by a debtor after the commencement of a case under
the Bankruptcy Code may be subject to a lien resulting from any security agreement
entered into the debtor before the commencement of the case; and
	 
	 	(vi)	 	under certain circumstances described in Section 9-320 of each of the DE UCC
and MA UCC, purchasers of collateral may take the same free of a perfected security
interest.

     Based on the foregoing, and subject to the qualifications set forth herein, it is our opinion
that:

     1. The Borrower is a validly existing corporation, in good standing under the laws of the
State of Delaware, and has the requisite power and authority to own its properties and, to our
knowledge, to transact the business in which it is engaged.

     2. Planergy is a validly existing corporation, in good standing under the laws of the State of
Delaware. Each of Exelon, Hawaii, Solar-Products, Solar, Solar-Technologies, Woodland and
Northampton is a limited liability company validly existing and in good standing under the laws of
the State of Delaware. Select is a corporation validly existing and in good standing under the
laws of the Commonwealth of Massachusetts. Each of the Delaware or Massachusetts Parties has the
requisite power and authority to own its respective properties and, to our knowledge, to transact
its respective business in which it is engaged.

     3. The Borrower and each Delaware or Massachusetts Party have the power to execute, deliver
and carry out the terms and provisions of each of the Loan Documents to which the Borrower and each
Delaware or Massachusetts Party is a party, and the Borrower and each Delaware or Massachusetts
Party have taken or caused to be taken all necessary action to authorize the execution, delivery
and performance of each of the Loan Documents to which the Borrower or any such Delaware or
Massachusetts Party, as applicable, is a party.

     4. Neither the execution and delivery of the Loan Documents by the Borrower or any of the
Delaware or Massachusetts Parties who is a party thereto, nor compliance with any of the provisions
thereof, will violate any law or regulation applicable to the Borrower or any Delaware or
Massachusetts Party, result in the creation or imposition of any Lien upon any of the property of
the Borrower or any Delaware or Massachusetts Party (except in favor of the Administrative Agent)
or, to our knowledge, any order or decree of any court or governmental instrumentality specifically
naming the Borrower or any Delaware or Massachusetts Party or violate any provision of any of the
Organizational Documents of the Borrower or any Delaware or Massachusetts Party.

     5. The execution, delivery and performance of the Loan Documents by each of the Borrower and
each Delaware or Massachusetts Party, respectively, does not require and will not require the
consent of, any exemption by, or any registration or filing (other than filing the

7

 

Financing Statements pursuant to the MA UCC or DE UCC, as applicable) with any court,
government or regulatory authority.

     6. Each of the Loan Documents has been duly executed and delivered by each of the Credit
Parties which is a party thereto. The Loan Documents are the valid and binding obligations of each
of the Credit Parties, to the extent each of them is a party thereto, enforceable against each such
Credit Party in accordance with their respective terms.

     7. Relying upon the representations and warranties of the Borrower in Section 5.8 of the
Credit Agreement, the Borrower and the Guarantors are not individually or collectively (a) an
“investment company” within the meaning of the Investment Company Act of 1940, as amended, or (b) a
“bank holding company” within the meaning of the Bank Holding Company Act of 1956, as amended.

     8. Assuming that (a) each of the Credit Parties has authenticated the provisions in Section
4.1 of the Credit Agreement that provide a description of the Collateral, (b) value has been given
to the Credit Parties by the Administrative Agent and each other party seeking to obtain the
benefit of the Credit Agreement and Pledge Agreement and (c) the Credit Parties (other than the
Non-Delaware or Massachusetts Companies) have rights in such collateral as contemplated by Section
9-203 of the MA UCC, the Credit Agreement creates in favor of the Agent, for its own benefit and
the ratable benefit of the other Lenders, a valid and enforceable security interest in that part of
the Collateral in which a security interest may be created under Article 9 of the MA UCC.

     9. Under the MA UCC (including the conflict of laws provisions thereof), the internal laws of
the Commonwealth of Massachusetts (with respect to Select) and the State of Delaware (with respect
to Planergy, Exelon, Hawaii, Solar-Products, Solar, Solar-Technologies, Woodland and Northampton)
govern the perfection, by the filing of financing statements, of the Administrative Agent’s
security interest in the Collateral of each Credit Party (other than the Non-Delaware or
Massachusetts Companies) in which a security interest may be perfected by filing. Upon the proper
filing of the UCC Financing Statements in the Office of the Secretary of the Commonwealth of
Massachusetts (with respect to Select) and the Office of the Secretary of State of the State of
Delaware (with respect to Planergy, Exelon, Hawaii, Solar-Products, Solar, Solar-Technologies,
Woodland and Northampton), assuming the accuracy of the assumptions in paragraph 8, the security
interests of the Administrative Agent on behalf of the Lenders in the Collateral in which a
security interest may be created under Article 9 of the MA UCC or DE UCC, as applicable, will be
perfected to the extent that the MA UCC or DE UCC, as applicable, provides that such security
interests may be perfected solely by the filing of financing statements.

     10. Assuming that (a) any certificated securities or instruments (as such terms are defined in
the MA UCC) which constitute part of the Collateral (as defined in the Credit Agreement) are
delivered to the Administrative Agent in The Commonwealth of Massachusetts and that the
Administrative Agent takes possession of such certificated securities or instruments in good faith
and without notice, prior to or on the date of such delivery, of an adverse claim thereto, within
the meaning of the MA UCC, and further assuming that the Administrative Agent retains continuous
possession thereof, (b) value has been given to the Borrower by the

8

 

Administrative Agent and each other party seeking to obtain the benefit of the Pledge
Agreement, and (c) the Borrower has rights in such Collateral as contemplated by Section 9-203 of
the MA UCC, the security interest granted to the Administrative Agent by the Borrower pursuant to
the Pledge Agreement creates in favor of the Administrative Agent a perfected security interest in
the Borrower’s right, title and interest in any such certificated securities or instruments in
favor of the Administrative Agent.

     11. Relying upon the representations and warranties of the Borrower in Section 5.15 of the
Credit Agreement, the making of the Loans, the use of the proceeds thereof as required by the
Credit Agreement and the security arrangements contemplated by the Loan Documents will not violate
or be inconsistent with any of the provisions of Regulation T, U or X of the Board of Governors of
the Federal Reserve System.

     We render no opinion on matters except as specifically stated herein. This opinion is given
and speaks only as of the date hereof and is limited to our knowledge of the facts and the laws,
statutes, rules and regulations, and judicial and administrative interpretations thereof, as
currently in effect. These are all subject to change and such change may be made with retroactive
effect. We assume no obligation to advise the Administrative Agent or other Lenders of changes of
any kind that may hereafter be brought to our attention even if such changes would affect our
opinion or to update or supplement this opinion after the date hereof. This opinion is solely for
the benefit of the Administrative Agent and other Lenders solely in connection with the closing
this day under the Credit Agreement, is not to be used or relied upon by such Persons for any other
purpose, and may not be furnished, quoted or otherwise referred to, or relied upon by any other
Person for any purpose without our prior written consent, except that this opinion may be relied
upon by independent auditors and financial institutions in connection the participation or
assignment of the interests of the Administrative Agent and Lenders in the Loan Documents, as
permitted by the terms thereof.

Very truly yours

FORM OF SOLVENCY CERTIFICATE

     The undersigned, Chief Financial Officer of Ameresco, Inc., a Delaware corporation (the
“Borrower”) is duly authorized to execute this certificate on this           
           day of June, 2008, on
behalf of itself and the Guarantors under the Credit Agreement defined below.

W I T N E S S E T H:

     WHEREAS, the Borrower has entered into an Amended and Restated Credit and Security Agreement
dated as of the date hereof (as amended and modified from time to time, the “Credit Agreement”;
capitalized terms used but not otherwise defined herein shall have the meanings provided in the
Credit Agreement) with the Guarantors party thereto (the “Guarantors” and together with the
Borrower, the “Credit Parties”), the Lenders from time to time party thereto, and Bank of America,
N.A., as administrative agent (the “Agent”), pursuant to which the Lenders have established credit
facilities in the aggregate principal amount of $50,000,000 (the “Credit Facilities”) in favor of
the Borrower;

     WHEREAS, each of the Credit Parties will benefit substantially and directly from the
establishment of the Credit Facilities in favor of the Borrower;

     WHEREAS, to secure their respective obligations under and relating to the Credit Facilities,
the Credit Parties have executed and delivered to the Agent the Loan Documents referenced in the
Credit Agreement (the grant of security interests, transfers, incurrence of obligations and other
transactions relating to the execution, delivery and performance of the obligations under the Loan
Documents, and any other transactions and transfers related thereto, shall be referred to herein
collectively as the “Transactions”);

     WHEREAS, the undersigned has carefully reviewed the Credit Agreement and the various other
Loan Documents, and also the contents of this Certificate, and in connection herewith has made such
investigations and inquiries as he has deemed reasonably necessary and prudent therefor, and
further acknowledges that the Agent and the Lenders are relying on the truth and accuracy of this
Certificate in connection with the establishment of the Credit Facilities;

     WHEREAS, the following terms, as used in this Certificate, shall have the following meanings:

     “fair value” shall mean the amount at which the assets of an entity would change hands
between a willing buyer and a willing seller, within a commercially reasonable period of
time, each having knowledge of the relevant facts, neither being under any compulsion to
act, with equity to both;

 

 

     “indebtedness” shall mean all obligations and liabilities, whether matured or
unmatured, liquidated or unliquidated, disputed or undisputed, secured or unsecured, or
subordinated, and also includes all identified contingent liabilities;

     “identified contingent liabilities” shall mean the maximum reasonably estimated
liabilities that may result from pending litigation, asserted claims and assessments,
guaranties, environmental conditions, uninsured risks, and other contingent obligations
known to management;

     “present fair saleable value” shall mean the amount that may be realized within a
reasonable time, considered to be six months to one year, either through collection or sale
at the regular market value, conceiving the latter as the amount which could be obtained for
such properties within such period by a capable and diligent businessman from an interested
buyer who is willing to purchase under ordinary selling conditions).

     NOW, THEREFORE, ON THE BASIS OF THE FOREGOING, and the inquiries and considerations set forth
below, the undersigned hereby certifies that, both before and after giving effect to the
consummation of the Transactions:

     1. I am, and at all pertinent times mentioned herein, have been, the duly qualified and acting
Chief Financial Officer of the Borrower, and have responsibility for the management of the
financial affairs of the Credit Parties, and the preparation of the financial statements of the
Credit Parties.

     2. The financial information, projections and assumptions which underlie and form the basis
for the representations made in this Certificate were believed by the Credit Parties to be fair and
reasonable when made, were accurately computed and were made in good faith and continue to be
believed by the Credit Parties to be reasonable as of the date hereof.

     3. I have carefully reviewed the contents of this Certificate, and I have conferred with
counsel for the purpose of discussing the meaning of this Certificate.

     4. The fair value and present fair saleable value on a going concern basis of all assets and
property of the Credit Parties, on a consolidated basis, is greater than the total amount of
indebtedness of the Credit Parties, on a consolidated basis.

     5. The aggregate fair value and present fair saleable value on a going concern basis of the
assets of the Credit Parties, on a consolidated basis, exceeds the amount that will be required to
pay the probable liabilities of the Credit Parties, on a consolidated basis, in respect of their
indebtedness, as such indebtedness becomes absolute and matured.

     6. The Credit Parties, on a consolidated basis, do not and will not have an unreasonably small
capital for them to carry on their businesses as now conducted and as proposed to be conducted
after the closing of the Transactions. The undersigned recognizes that “unreasonably small
capital” is dependent upon the nature of the particular business or businesses conducted or to be
conducted, and the statement made in the preceding sentence is

2

 

based upon the current and anticipated future capital requirements for the current and
anticipated future conduct of the businesses of the Credit Parties.

     7. The Credit Parties, on a consolidated basis, will have sufficient cash flow to enable them
to pay their debts as they mature.

     8. The Credit Parties, on a consolidated basis, do not intend or believe that they have or
will incur indebtedness that is or will be beyond their ability to pay as such indebtedness
matures.

     9. The Credit Parties, on a consolidated basis, do not intend, in consummating the
Transactions, to hinder, delay, or defraud either present or future creditors or any other person
to which the Credit Parties, on a consolidated basis, are or will become, on or after the date
hereof, indebted.

first mentioned above, on behalf of the Credit Parties.

     6. Base Year for Operating Expenses. The Base Year for Operating Expenses shall be
calendar year 2010. Section 9.1 of the Lease, is modified as follows: The definition of “Operating
Expenses” as originally set forth therein shall now be modified to include the following: There
shall be no escalation charges for the first twelve months of the Term and the Base Year shall be
calculated on a full twelve month period, with such calculation reflecting a fully occupied
building. It is also understood that the management fee previously allowed shall now be more
specifically defined by including the following: Operating Expenses shall include a management fee

Notice to Landlord.

     10. Tenant Electricity. Landlord shall install a check-meter or submeter, within
sixteen (16) weeks after execution of this Amendment, which will measure Tenant’s actual
consumption of electricity in the Premises. From and after the date such meter is placed into
service, the third sentence of Section 7.4(b) of the Lease is amended in its entirety to state as
follows: “Landlord shall charge Tenant for (i) all electricity consumed in the Premises based on
check-meter or submeter readings, at the same rate as is charged to Landlord by the applicable
utility provider, plus (ii) as part of operating expenses, Tenant’s Proportionate Share of the
electricity and natural gas used in connection with the HVAC system and common areas for the
Building. Landlord shall provide Tenant with submeter readings and electric bill and rate
information so that Tenant can verify the amounts charged by Landlord to Tenant. From and after
the date such meter is placed into service, the definition “Cost of Tenant’s Electricity for Lights
and Plugs,” as defined in Section 1.1 of the Lease shall be null and void.

     11. Renewal Option. In lieu of all other renewal options provided for in the Lease,
Tenant shall, provided Tenant is not in default under any of the material terms and conditions of
the Lease at the time of notification, have one (1) option to renew this Lease for a term of five
(5) years, for the portion of the Premises being leased by Tenant as of the date the renewal term

3

 

is to commence, on the same terms and conditions set forth in the Lease, except as modified by
the terms, and conditions as set forth below:

          (a) If Tenant elects to exercise said option, then Tenant shall provide Landlord with written
notice no earlier than the date which is twelve (12) months prior to the expiration of the Term of
the Lease but no later than the date which is nine (9) months prior to the expiration of the Term
of this Lease. If Tenant fails to provide such notice, Tenant shall have no further or additional
right to extend or renew the Term of the Lease.

          (b) The Basic Rent in effect at the expiration of the Term of the Lease shall be adjusted to
reflect the current fair market rental for comparable space in the Building and in other similar
buildings in the same rental market as of the date the renewal term is to commence, taking into
account the specific provisions of the Lease which will remain constant. Landlord shall advise
Tenant of the new Basic Rent for the Premises no later than sixty (60) days after receipt of
Tenant’s written request therefor. For purposes of this Lease, Tenant’s written exercise of the
option shall serve as the written request therefor. In no event shall the new Basic Rent be less
than the Basic Rent in the preceding period.

          (c) This option is not transferable; the parties hereto acknowledge and agree that they intend
that the aforesaid option to renew this Lease shall be “personal” to Tenant as set forth above and
that in no event will any assignee or sublessee have any rights to exercise the aforesaid option to
renew except for an affiliate of Tenant.

     12. Right of First Refusal to Lease. All previous rights of first offer and other
expansion rights provided for in the Lease are hereby deleted. In lieu thereof, provided Tenant is
not then in default under the Lease, Tenant shall have the right to lease, after expiration of the
current lease thereof, (i) approximately 1,172 rentable square feet on the 4th floor of
the Building as shown on Exhibit C, and (ii) approximately 1,474 rentable square feet on
the 4th floor of the Building as shown on Exhibit C (each, an “Expansion Space”)
at such time as Landlord receives an offer from a third party to lease an Expansion Space which
Landlord is prepared to accept (the “Offer”). In such a case, Landlord shall give written notice
to Tenant of the Offer, in all its particulars and Tenant shall have a period of ten (10) business
days in which to exercise Tenant’s right to lease the Expansion Space, failing which Landlord may
lease all or some portion of the Expansion Premises to the third party on the basis of the Offer.
In the event such third party does not lease the Expansion Space pursuant to the Offer, Landlord
shall be obligated to follow the foregoing procedure for any subsequent Offer which it receives.
If such third party does lease the Expansion Space pursuant to the Offer, Tenant’s right of first
refusal with respect to that Expansion Space shall continue. If Tenant exercises its option to
include the Expansion Space hereunder, effective on the delivery date specified in the Offer, the
Expansion Space shall automatically be included in the Premises and subject to all the terms and
conditions of the Lease, except as set forth in the Offer and as follows:

          (a) Tenant’s Proportionate Share shall be recalculated, using the total square footage of the
Premises, as increased by the Expansion Space.

4

 

          (b) Except as set forth in the Offer, the Expansion Space shall be leased on an “as is” basis
and Landlord shall have no obligation to improve the Expansion Space or grant Tenant any
improvement allowance thereon.

          (c) If requested by Landlord, Tenant shall, prior to the beginning of the term for the
Expansion Space, execute a written memorandum confirming the inclusion of the Expansion Space and
the Basic Rent for the Expansion Space.

          (d) Notwithstanding the foregoing, Tenant shall have no right to lease the Expansion Space if
the Termination Date under this Lease is prior to the date on which the term of the lease of the
Expansion Space would expire under the terms under which Landlord intends to offer the Expansion
Space to the public (“Expansion Termination Date”) (e.g., if only one year remains in the term of
this Lease but Landlord requires a minimum term of three years for the Expansion Space, Tenant
would have no right to lease the Expansion Space). However, if Tenant has a remaining renewal
option which, if properly exercised, would extend the Termination Date of this Lease to or beyond
the Expansion Termination Date, Tenant shall have the right to lease the Expansion Space if,
concurrently with its exercise of that right, it also exercises such renewal option.

          (e) The current term of the lease of the 1,172 RSF Expansion Space expires on May 31, 2012,
and the current term of the lease of the 1,474 RSF Expansion Space expires on April 30, 2012.
However, nothing herein shall be construed as to prohibit Landlord from extending the term of the
lease of any existing tenant or of any future tenant who first leases the Expansion Space after
compliance with this Paragraph 12.

          (f) This option is not transferable; the parties hereto acknowledge and agree that they intend
that the aforesaid right of first refusal shall be “personal” to Tenant as set forth above and that
in no event will any assignee or sublessee have any rights to exercise the aforesaid right except
for an affiliate of Tenant.

     13. Right of First Offer to Purchase. Landlord hereby grants to Tenant a Right of
First Offer to purchase the Property which includes the land in Framingham Massachusetts along with
the Building and other improvements, (for this Right of First Offer Period, hereinafter the
“Building”) during the “Right of First Offer Period,” which shall commence on the date of this
Amendment and shall terminate upon expiration of this Lease.

          (a) If, during the Right of First Offer Period, Landlord decides to sell the Building,
Landlord shall provide to Tenant a letter of intent specifying the specific terms upon which
Landlord wishes to sell the Building (the “Offering Notice”). If Tenant desires to purchase the
Building, Tenant shall, within fifteen (15) business days after receipt of the Offering Notice,
notify Landlord, in writing, either (i) that Tenant intends to exercise its Right of First Offer on
the terms stated in the Offering Notice, or (ii) that Tenant declines to exercise its Right of
First Offer. If Tenant fails to give such notice within such fifteen (15) business day period,
Tenant will be deemed to have declined to exercise its Right of First Offer. If Tenant declines,
or is deemed to have declined, to exercise its Right of First Offer, Tenant shall have no further
exclusive or special right or option to purchase the Building, and, at Landlord’s request,

5

 

Tenant shall so confirm in a recordable instrument. This shall not, however, preclude Tenant
from consideration as a purchaser in an open market purchase of the Building.

          (b) If the Building is sold to a third party after full compliance with the terms of this
Amendment and an Offering Notice, Tenant’s Right of First Offer thereafter shall be null and void
and shall not be binding on such purchaser nor applicable to any subsequent sale of the Building.

          (c) If Tenant decides to purchase the Building under the terms of the Offering Notice, the
Tenant shall within the fifteen (15) business day period execute the letter of intent presented by
the Landlord and make a non-refundable deposit per the terms of the letter of intent, and close the
transaction within 60 days.

          (d) Notwithstanding anything in the foregoing to the contrary, Tenant’s Right of First Offer
shall not apply to, and Tenant shall have no right to purchase the Building in connection with, (i)
the sale or transfer of the Building to an affiliate of Landlord or Landlord’s investment manager
(which sale or transfer shall not, however, void Tenant’s Right of First Offer on a later sale or
transfer in an arms length transaction), or (ii) the sale or proposed sale of the Building to a
third party where the Building is a portion of a package or portfolio sale including one or more
additional properties (and upon completion of such third party sale, Tenant’s Right of First Offer
shall be null and void).

          (e) This option is not transferable; the parties hereto acknowledge and agree that they intend
that the aforesaid right of first offer shall be “personal” to Tenant as set forth above and that
in no event will any assignee or sublessee have any rights to exercise the aforesaid right except
for an affiliate, or shareholder of Tenant.

     14. Commissions. Each of the parties represents and warrants that it has not dealt
with any broker or finder in connection with this Amendment, except for Richards Barry Joyce &
Partners, LLC, whose commission shall be paid by the Landlord pursuant to a separate agreement.
Each party agrees to indemnify and hold the other harmless from any and all claims for commissions
or fees in connection with the Premises and this Amendment from any other real estate broker or
agent.

     15. Parking Garage. The second sentence of Section 2.2(c) of the Original Lease, as
modified, is replaced in its entirety by the following: “Three (3) of Tenant’s Share of Parking
Spaces shall be available for Tenant’s use, on a non-exclusive, unreserved basis, in the parking
garage on the Property.”

     16. Assignment and Subletting. In the first sentence of Section 6.3 of the Lease, the
words “sixty percent (60%)” are replaced by “fifty percent (50%).”

     17. Relocation. Section 15.5 of the Lease is deleted in its entirety. Landlord shall
have no right of relocation.

6

 

     18. Signage. So long as Tenant is not in default and occupies not less than 20,357
rentable square feet in the Building, Tenant shall be permitted to install identification signage
on the exterior of the Building. Such signage (1) shall be consistent in size and quality with
existing and any previous such signage at the Building, (2) shall be installed at Tenant’s sole
expense, and only after first receiving Landlord’s approval of plans and specifications therefor,
such approval not to be unreasonably withheld, as well as any necessary permits, and (3) must
comply with all applicable laws, codes and ordinances. At the expiration or earlier termination of
the Term, Tenant shall remove all such signage and repair any damage caused by such removal, all at
Tenant’s sole cost and expense.

     19. Generator. Tenant will be permitted to install and maintain a generator, at its
sole expense, for use for emergency backup power, on Landlord’s property at a location designated
by Landlord, subject to the following terms and conditions:

          (a) The location of the generator must be acceptable to Landlord in its sole and absolute
discretion.

          (b) The specifications for the generator itself and for its installation, including mounting,

     22. Incorporation. Except as modified herein, all other terms and conditions of the
Lease and the Storage Space License shall continue in full force and effect and Tenant hereby
ratifies and confirms its obligations thereunder. Tenant acknowledges that as of the date of the
Amendment, Tenant (i) is not in default under the terms of the Lease; (ii) has no defense, set off
or counterclaim to the enforcement by Landlord of the terms of the Lease; and (iii) is not aware of
any action or inaction by Landlord that would constitute a default by Landlord under the Lease.

     23. Tenant’s Authority (OFAC). Tenant represents and warrants that Tenant has been
and is qualified to do business in the state in which the Building is located, that Tenant has full
right and authority to enter into this Lease, and that all persons signing on behalf of the entity
were authorized to do so by appropriate actions. Tenant agrees to deliver to Landlord,
simultaneously with the delivery of this Lease, a corporate resolution, proof of due authorization
by partners, or other appropriate documentation reasonably acceptable to Landlord evidencing the
due authorization of Tenant to enter into this Lease. To Tenant’s knowledge, neither Tenant, nor
any persons or entities holding any legal or beneficial interest whatsoever in Tenant, are (i) the
target of any sanctions program that is established by Executive Order of the President or
published by the Office of Foreign Assets Control, U.S. Department of the Treasury (“OFAC”); (ii)
designated by the President or OFAC pursuant to the Trading with the Enemy Act, 50 U.S.C. App. § 5,

pursuant to such statutes; or (iii) named on the following list that is published by OFAC: “List
of Specially Designated Nationals and Blocked Persons.” If the foregoing representation is untrue
at any time during the Term, an Event of Default will be deemed to have occurred, without the
necessity of notice to Tenant.

     24. Limitation of Landlord Liability. Redress for any claim against Landlord under
this Amendment and the Lease shall be limited to and enforceable only against and to the extent of
Landlord’s interest in the Property. The obligations of Landlord under this Amendment and the
Lease are not intended to be and shall not be personally binding on, nor shall any resort be had to
the private properties of, any of its or its investment manager’s trustees, directors, officers,
partners, beneficiaries, members, stockholders, employees, or agents, and in no case shall Landlord
be liable to Tenant hereunder for any lost profits, damage to business, or any form of special,
indirect or consequential damages.

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of the day and year
first written above.

     3.2 Each disbursement of the TI Allowance shall be subject to satisfaction of each of the
following conditions as of the time of such disbursement:

          3.2.1 The disbursement should be based upon a schedule of values provided by Tenant indicating
the percent complete and or materials purchased and/or on site, subject to retention of up to ten
per cent (10%) excluding the final disbursement and any excess balance as is described below of up
to $78,883.38 which may be applied to Rent; and

          3.2.2 Receipt by Landlord of sworn statements, waivers of lien and other documents and
assurances pertaining to the Tenant’s Work sufficient to protect Landlord against mechanics’ and
other liens; and

          3.2.3 Receipt of assurances satisfactory to Landlord that the undisbursed balance of the TI
Allowance after such disbursement is adequate to complete the remaining Tenant’s Work; and

          3.2.4 Tenant is then in full compliance with all the terms and provisions of the Lease and has
not committed or suffered any act or omission which constitutes, or will constitute with the
passage of time, an incurable Event of Default of Tenant under the Lease or a material breach by
Tenant of any term or provision of this Agreement.

     3.3 Notwithstanding the foregoing, until such time as Tenant has decided to apply the excess
balance of $78,883.38 as is described below at which such time, withholding shall cease, Landlord
shall be entitled to withhold up to 10% of any draw request to be disbursed upon completion of the
Tenant’s Work as assurance that the Tenant’s Work will be properly completed. Any final
disbursement from the deposit will also be conditioned upon Tenant’s satisfaction of its
obligations under Paragraph 5 below.

shall be borne by Tenant. If the TI Allowance amount exceeds the total cost of Tenant’s Work,
Tenant may apply such excess, up to a maximum of $78,883.38, as a credit against base rent. The TI
Allowance may only be applied towards the cost of actual improvements to the Premises, and not the

shall have no obligation to disburse any portion of the TI Allowance as to which the conditions to
disbursement thereof are not satisfied by June 30, 2012.

4. Contracts and Contractors for the Tenant’s Work. Tenant shall make all such contracts
and arrangements as shall be necessary or desirable for the construction and installation of the
Tenant’s Work. Tenant agrees to retain contractors, subcontractors and materialmen who are of good
reputation and experienced in and favorably known for the construction of space comparable to the
Premises in the metropolitan area where the Building is located and that are properly licensed for
the work they are to perform. Tenant shall provide Landlord with a list of all contractors,
subcontractors and materialmen to be utilized by or for Tenant with respect to the Tenant’s Work
and provide true, correct and complete copies of all contracts relating to the Tenant’s Work. Such
contractors, subcontractors, materialmen and contracts must be satisfactory to Landlord in
Landlord’s reasonable discretion, and shall not be employed or executed, as the case may be,
without Landlord’s written approval first obtained which approval shall not be unreasonably
withheld, conditioned, or delayed. Tenant and Tenant’s contractors shall use qualified craftsmen
and laborers who are compatible with the trade unions operating in the Building (if any) and Tenant
shall take promptly upon Landlord’s written demand all reasonable measures necessary to avoid labor
unrest in the Premises and in the Building which is caused by Tenant or Tenant’s contractors.
Before commencing any work in the Building, Tenant and its contractor must acknowledge in writing
that they have received, reviewed and agreed to be bound by Landlord’s Construction Rules and
Regulations for the Building, a copy of which is attached to this Exhibit as Schedule IV.

5. Construction. Promptly upon Landlord’s approval of the Tenant’s Plans, Tenant shall
apply for, and supply to Landlord upon issuance, a building permit and any other required
governmental permits, licenses or approvals. Upon issuance of such approvals, Tenant shall
commence the Tenant’s Work and shall diligently prosecute the Tenant’s Work to completion. Tenant
agrees to cause the Tenant’s Work to be constructed in a good and workmanlike manner using
materials specified in the Tenant’s Plans or their reasonable equivalent (first-class quality
materials, if not specified), at its sole cost and expense in accordance with the provisions of the
Lease. Any costs incurred by Landlord in providing utilities, supervision or other services needed
for the accomplishment of the Tenant’s Work shall be reimbursed by Tenant to Landlord. Upon
completion of the Tenant’s Work, to the extent appropriate, Tenant shall provide to Landlord: (i)
an architect’s certificate of final completion; (ii) copies of all necessary governmental permits,
including, but not limited to, a certificate of occupancy; (iii) the sworn statement of the general
contractor; (iv) final lien waivers from all contractors, subcontractors and materialmen; and (v)
any other information or documentation reasonably requested in writing by Landlord to evidence
lien-free completion of construction and payment of all of the cost thereof. Landlord shall have
the right to observe the performance of the Tenant’s Work and Tenant shall take all such actions
with respect thereto as Landlord may, in its good faith determination, deem advisable from time to
time to assure that the Tenant’s Work and the manner of performance thereof shall not be injurious
to the engineering and construction of the

6. Miscellaneous.

     6.1 All rights and remedies of Landlord herein created or otherwise existing at law or equity
are cumulative, and the exercise of one or more such rights or remedies shall not be deemed to
exclude or waive the right to the exercise of any other rights or remedies. All such rights and
remedies may be exercised and enforced concurrently and whenever and as often as deemed desirable.

     6.2 This Exhibit B shall not be deemed applicable to any additional space added to the
original Premises at any time or from time to time, whether by any options under the Lease or
otherwise, or to any portion of the original Premises or any additions thereto in the event of a
renewal or extension of the original term of the Lease, whether by any options under the Lease or
otherwise.

     6.3 Tenant shall, before commencing any of the Tenant’s Work, and for so long as any Tenant’s
Work shall continue, comply with the insurance requirements in Schedule III and
Schedule IV. In the event Tenant fails to so comply, Landlord shall have the option, but
not the obligation to procure the required insurance and charge Tenant the cost of such compliance
as additional rent.

lesser standard as shall be acceptable to Landlord and authorized to transact business in the state
in which the Building is located, protecting Landlord against liabilities arising out of the
operations of subcontractors and sub-subcontractors as well as Tenant’s contractor (“Contractor”)
with respect to all the Tenant’s Work, including at least and in amounts not less than:

          (a) Worker’s Compensation & Employers Liability: Statutory limits required by applicable

agreements contained in the Contract Documents, personal injury (employees’ exclusion deleted)
$5,000,000 per occurrence Bodily Injury and Property Damage, $5,000,000 combined single limit.

require deletion of the “x, c, u” exclusion, if applicable.

          (c) Comprehensive Auto Liability including owned, non-owned, or hired vehicles coverage:

in subparagraph (d) above and Tenant shall reimburse Landlord for the actual cost thereof.

     2. Contractor shall either have the Landlord added as an additional named insured to the
preceding Commercial or Comprehensive General Liability insurance policy or shall supply a separate
Landlord’s Protective policy, with limits as specified, naming the Landlord as named insured, and
said General Liability or Landlord’s Protective policy shall be maintained in force until the

Landlord. To the extent the policy is not a Landlord’s Protective policy, it shall be
endorsed to indicate that it is primary as respects Landlord, not contributory with any other
insurance available to the Landlord and not subject to reduction of coverage as to Landlord by
reason of any claim asserted against Contractor other than in connection with the Tenant’s Work or
by reason of any misstatement, act or omission of any party other than Landlord applying for or
insured by such insurance.

     4. Each insurance policy and any certificate furnished in lieu of a policy shall state that it
will not be cancelled, reduced or materially changed without thirty (30) days’ prior written notice
to Landlord. In the event Tenant fails to provide replacement coverage at least three (3) business

insurance and Tenant shall reimburse Landlord for the cost thereof as additional rent; but Landlord
shall not have any obligation to secure any such insurance.

the event of foreclosure of the Mortgage and Lender wishes to have Lessee confirm the priority of
the Mortgage over the Lease.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions set forth herein, the
parties hereto agree as follows:

     7. Lessee hereby covenants and agrees that all its rights and interests whatsoever under the
Lease in the Leased Premises and the Property are and shall remain subject and subordinate to the
lien of the Mortgage, to all of the rights and interests of Lender under the Mortgage and to all
the terms, conditions and provisions thereof, to all advances made or to be made thereunder or
under the Note, and to any increases, renewals, extensions, modifications, substitutions,
consolidations or replacements thereof or of the Note.

     8. So long as Lessee is not in default (beyond any period given Lessee in the Lease to cure
such default) in the payment of rent or additional charges or in the performance of any of the
other terms, covenants or conditions of the Lease on its part to be performed, Lessee shall not be
disturbed by Lender in its possession of the Leased Premises during the term of the Lease, or any
extension or renewal thereof, or in the enjoyment of Lessee’s rights under the Lease.

     9. If the interest of the Lessor under the Lease shall be acquired by Lender or any purchaser
(“Purchaser”) by reason of exercise of the power of sale or the foreclosure of the Mortgage or
other proceedings brought to enforce the rights of the holder thereof, by deed in lieu of
foreclosure or by any other method, and Lender or Purchaser succeeds to the interest of Lessor
under the Lease, Lessee shall attorn to Lender or Purchaser as its lessor, said attornment to be
effective and self-operative without the execution of any other instruments on the part of either
party hereto immediately upon Lender’s or Purchaser’s succeeding to the interest of the Lessor

under the Lease, and the Lease shall continue in accordance with its terms between Lessee as
lessee and Lender or Purchaser as lessor; provided, however, that:

          (a) Lender or Purchaser shall not be personally liable under the Lease and Lender’s or
Purchaser’s liability under the Lease shall be limited to the ownership interest of Lender or
Purchaser in the Property;

          (b) Lender or Purchaser shall not be liable for any act or omission of any prior lessor
(including Lessor);

          (c) Lender or Purchaser shall not be subject to any offsets or defenses which Lessee might
have against any prior lessor (including Lessor);

          (d) Lender or Purchaser shall not be bound by any prepayment of rent or deposit, rental
security or any other sums deposited with any prior lessor (including Lessor) under the Lease, with
the exception of the Prepayment of Monthly Rent pursuant to the Amendment, unless actually received
by Lender or Purchaser;

          (e) Lender or Purchaser shall not be bound by any agreement or modification of the Lease made
without Lender’s or Purchaser’s written consent;

          (f) Lender or Purchaser shall not be bound to commence or complete any construction or to make
any contribution toward construction or installation of any improvements upon the Leased Premises
or the Property required under the Lease or any expansion or rehabilitation of existing
improvements thereon, or for the payment of any tenant allowance or incentive, or for restoration
of improvements following any casualty not required to be insured under the Lease or for the costs
of any restorations in excess of any proceeds recovered under any insurance required to be carried
under the Lease; and

          (g) Lender or Purchaser shall not be bound by any radius restriction or other restriction on
competition beyond the Property.

The obligation of Lessee to attorn as described in this Paragraph 3 is independent of Lender’s
nondisturbance obligation under Paragraph 2. Lessee expressly acknowledges and agrees that a
default by Lessee under the Lease (beyond any period given Lessee in the Lease to cure such
default), (i) shall terminate Lender’s nondisturbance obligation, and (ii) shall not terminate
Lessee’s attornment obligation or any other agreements by Lessee set forth herein; provided,
however, at Purchaser’s sole option, Purchaser may elect to reject Lessee’s attornment by written
notice to Lessee delivered within thirty (30) days following acquisition of the interest of Lessor.
If Purchaser accepts such attornment, Purchaser shall be entitled to exercise any or all of its
rights and remedies under the Lease and/or at law or in equity by reason of default by Lessee under
the Lease (beyond any period given Lessee in the Lease to cure such default).

     10. Lessee certifies to Lender that the Lease is presently in full force and effect with no
defaults thereunder by Lessor or by Lessee and unmodified except as indicated hereinabove; that the
term thereof has commenced and the full rental is now accruing thereunder; that Lessee has accepted
possession of the Leased Premises and that any improvements required by the terms

of the Lease to be made by Lessor have been completed to the satisfaction of Lessee; that any
tenant allowances or other payments to be made by Lessor to Lessee have been made; that no rent
under the Lease has been paid more than thirty (30) days in advance of its due date; that the
address for notices to be sent to Lessee is as set forth in the Lease; and that Lessee has no
charge, lien, claim or offset under the Lease or otherwise, against rents or other charges due or
to become due thereunder.

     11. Lessee agrees with Lender that from and after the date hereof, Lessee will not enter into
any agreements amending the Lease without Lender’s prior written consent and that Lessee will not
terminate or seek to terminate the Lease by reason of any act or omission of the Lessor thereunder
until Lessee shall have given written notice, by certified mail, return receipt requested, of said
act or omission to Lender, which notice shall be addressed to Massachusetts Mutual Life Insurance
Company, c/o Babson Capital Management LLC, 1500 Main Street, Suite 2100, Springfield,
Massachusetts 01115-5189, Attention: Managing Director, Real Estate Investment Division, and until
a reasonable period of time shall have elapsed following the giving of such notice, but not greater
than ninety (90) days, during which period Lender shall have the right, but shall not be obligated,
to remedy such act or omission.

     12. Lessee covenants that it will not subordinate the Lease to any other mortgage or deed of
trust without Lender’s prior written consent.

     13. Lessor, by its execution of this Agreement, does hereby authorize Lessee to make all rent
and additional rent payments due under the Lease to Lender, should Lender notify Lessee in writing
that Lender is invoking its right under the Mortgage to receive all rent and additional rent
payments due under the Lease.

     14. This Agreement shall inure to the benefit of and shall be binding upon Lessee and Lender,
and their respective heirs, personal representatives, successors and assigns. This Agreement may
not be altered, modified or amended except in writing signed by all of the partied hereto. In the
event any one or more of the provisions contained in this Agreement shall for any reason be held to
be invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Agreement, but this Agreement shall
be construed as if such invalid, illegal or unenforceable provision had never been contained
herein. This Agreement shall be governed by and construed according to the laws of the state where
the Property is located.
