     G. All terms, covenants and conditions contained in this Amendment shall have the same meaning
as in the Lease, and shall govern should a conflict exist with previous terms and conditions.

AGREEMENT:

     NOW, THEREFORE, in consideration of the foregoing recitals and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant
hereby agree as follows:

     1. Recitals. The recitals set forth above are hereby incorporated herein as if fully
set forth.

 

 

     2. Capitalized Terms. All capitalized terms used herein shall have the same meanings
ascribed to them in the Lease, unless otherwise defined in the Amendment.

     3. Additional Space. Tenant wishes to lease from Landlord, and Landlord wishes to
lease to Tenant, in addition to the Current Premises, approximately 5,362 rentable square feet of
space on the fourth floor of the Building as approximately depicted on Exhibit A, attached
hereto and incorporated herein (the “Additional Space”). Effective on the date on which Landlord
tenders possession of the Additional Space to Tenant with Landlord’s Work under Exhibit B
substantially complete (the “Additional Space Commencement Date”), the Premises subject to the
Lease shall consist of the Current Premises as expanded to include the Additional Space totaling
20,357 rentable square feet, and all references in the Lease to the “Premises” shall refer to such
expanded space.

     4. Term. The existing Term, which is scheduled to expire December 31, 2008, is hereby
extended to expire on December 31, 2010.

     5. Rent Schedule. For the Additional Space, effective the Additional Space
Commencement Date, Tenant shall pay $11,617.67 monthly as Basic Rent. In addition for the Current
Premises, Tenant shall continue to pay Basic Rent as provided for in the Lease through December 31,
2008 and effective January 1, 2009, Tenant shall pay Basic Rent for the entire Premises, as herein

     6. Condition of Premises.

          (a) Tenant acknowledges that Landlord shall have no obligation to perform any construction or
make any additional improvements or alterations, or to afford any allowance to Tenant for
improvements or alterations, in connection with this Amendment, other than as is set forth in this
Paragraph 6. Except as is provided in this Paragraph 6, Tenant accepts the Additional Space in its
“as is” condition.

          (b) Landlord shall tender possession of the Additional Space with all the work to be performed
by Landlord pursuant to Exhibit B to this Lease substantially completed, endeavoring to do
so by July 1, 2007, provided that Landlord effectuates an early termination of the existing
tenant’s lease and a timely vacating of such space (the “Scheduled Commencement Date”). Tenant
shall deliver a punch list of items not completed within thirty (30) days after Landlord tenders
possession of the Additional Space and Landlord agrees to proceed with due diligence to perform its
obligations regarding such items. Tenant shall, at Landlord’s request, execute and deliver a
memorandum agreement provided by Landlord in the form of Exhibit C attached hereto, setting
forth the actual Additional Space Commencement Date, Termination Date and, if necessary, a revised
rent schedule to take into consideration any changes of dates in the rent schedule as provided in
this Amendment. Should Tenant fail to do so within thirty (30) days after Landlord’s request, the
information set forth in such memorandum provided by Landlord shall be conclusively presumed to be
agreed and correct.

 

 

          (c) Tenant agrees that in the event of the inability of Landlord to deliver possession of the
Additional Space on the Scheduled Commencement Date for any reason, Landlord shall not be liable
for any damage resulting from such inability and Tenant shall continue in occupancy of, and paying
rent on account of, the Current Premises at the rate payable under the Lease; but Tenant shall not
be liable for any rent for the Additional Space until the time when Landlord can, after notice to
Tenant, deliver possession of the Additional Space to Tenant. No such failure to give possession
on the Scheduled Commencement Date shall affect the other obligations of Tenant under this Lease,
except that if Landlord is unable to deliver possession of the Additional Space within one hundred
twenty (120) days after the Scheduled Commencement Date (other than as a result of strikes,
shortages of materials, tenancies or similar matters beyond the reasonable control of Landlord and
Tenant is notified by Landlord in writing as to such delay), Tenant shall have the option to
deliver a termination notice, unless and to the extent that said delay is as a result of: (a)
Tenant’s failure to agree to plans and specifications and/or construction cost estimates or bids;
(b) Tenant’s request for materials, finishes or installations other than Landlord’s standard except
those, if any, that Landlord shall have expressly agreed to furnish without extension of time
agreed by Landlord; (c) Tenant’s material change in plans or specifications; or, (d) performance or
completion by a party employed by Tenant (each of the foregoing, a “Tenant Delay”). If any delay
is the result of a Tenant Delay, the Additional Space Commencement Date and the payment of rent as
set forth in this Amendment shall be accelerated by the number of days of such Tenant Delay.
Subject to the foregoing, if Landlord fails to substantially complete such work and deliver
possession of the Additional Space within thirty (30) days after delivery of the termination
notice, this Amendment shall be cancelled and of no force or effect, and the Lease shall continue
in full force and effect without reference to this Amendment.

          (d) Landlord shall permit Tenant, or any agent, employee or contractor of Tenant, after the
existing tenant has vacated the Additional Space, to enter, use or occupy the Additional Space
prior to the Additional Space Commencement Date for the purpose of installing Tenant’s furniture,
fixtures and equipment. Such entry, use or occupancy shall be subject to all the provisions of
this Lease other than the payment of any increase in rent pursuant to this Amendment for the period
of time prior to the Additional Space Commencement Date. Said early possession shall not advance
the Termination Date.

     7. Tenant’s Proportionate Share For the Additional Space. Effective as of the
Additional Space Commencement Date, Tenant’s Proportionate Share for the Additional Space shall be
4.67% .

     8. Base Year for Operating Expenses for the Additional Space. Calendar year 2008;
provided that if the Additional Space Commencement Date is prior to August 1, 2007, then the Base
Year is calendar year 2007.

     9. Base Year for Taxes for the Additional Space. Calendar year 2008; provided that if
the Additional Space Commencement Date is prior to August 1, 2007, then the Base Year is calendar
year 2007.

     10. Security Deposit. None.

 

 

     11. Estimated Cost of Electrical Service. Effective the Additional Space Commencement
Date, Tenant shall pay Cost of Tenant’s Electricity for Lights & Plugs attributable to the
Additional Space at the rate of $7,238.70 annually in monthly installments of $603.23 in addition
to the monthly payments for Cost of Tenant’s Electricity for Lights & Plugs for the Current
Premises.

     12. Use and Restrictions on Use. Sections 5.1, 5.3 and 5.4 of the Original Lease
shall be deleted in their entirety and the following substituted therefor:

          (a) “The Premises are to be used solely for general office purposes. Tenant shall not do or
permit anything to be done in or about the Premises which will in any way obstruct or interfere
with the rights of other tenants or occupants of the Building or injure, annoy, or disturb them, or
allow the Premises to be used for any improper, immoral, unlawful, or objectionable purpose, or
commit any waste. Tenant shall not do, permit or suffer in, on, or about the Premises the sale of
any alcoholic liquor without the written consent of Landlord first obtained. Tenant shall comply
with all governmental laws, ordinances and regulations applicable to the use and occupancy of the
Premises by Tenant and shall promptly comply with all governmental orders and directions for the
correction, prevention and abatement of any violations in the Building or appurtenant land, caused
or permitted by, or resulting from the specific use by, Tenant, or in or upon, or in connection
with, the Premises, all at Tenant’s sole expense. Tenant shall not do or permit anything to be
done on or about the Premises or bring or keep anything into the Premises which will in any way
increase the rate of, invalidate or prevent the procuring of any insurance protecting against loss
or damage to the Building or any of its contents by fire or other casualty or against liability for
damage to property or injury to persons in or about the Building or any part thereof, other than as
permitted herein.

          (b) Tenant shall not, and shall not direct, suffer or permit any of its agents, contractors,
employees, licensees or invitees (collectively, the “Tenant Entities”) to at any time handle, use,
manufacture, store or dispose of in or about the Premises or the Building any (collectively
“Hazardous Materials”) flammables, explosives, radioactive materials, hazardous wastes or
materials, toxic wastes or materials, or other similar substances, petroleum products or
derivatives or any substance subject to regulation by or under any federal, state and local laws
and ordinances relating to the protection of the environment or the keeping, use or disposition of
environmentally hazardous materials, substances, or wastes, presently in effect or hereafter
adopted, all amendments to any of them, and all rules and regulations issued pursuant to any of
such laws or ordinances (collectively “Environmental Laws”), nor shall Tenant suffer or permit any
Hazardous Materials to be used in any manner not fully in compliance with all Environmental Laws,
in the Premises or the Building and appurtenant land or allow the environment to become
contaminated with any Hazardous Materials. Notwithstanding the foregoing, Tenant may handle,
store, use or dispose of products containing small quantities of Hazardous Materials (such as
aerosol cans containing insecticides, toner for copiers, paints, paint remover and the like) to the
extent customary and necessary for the use of the Premises for general office purposes; provided
that Tenant shall always handle, store, use, and dispose of any such Hazardous Materials in a safe
and lawful manner and never allow such Hazardous Materials to contaminate the Premises, Building
and appurtenant land or the environment. Tenant shall protect, defend, indemnify and hold each and
all of the Landlord Entities (as defined in Lease) harmless from and against any and all loss,
claims, liability or costs (including court costs and

 

 

attorney’s fees) incurred by reason of any actual or asserted failure of Tenant to fully
comply with all applicable Environmental Laws, or the presence, handling, use or disposition in or
from the Premises of any Hazardous Materials by Tenant or any Tenant Entity (even though
permissible under all applicable Environmental Laws or the provisions of this Lease), or by reason
of any actual or asserted failure of Tenant to keep, observe, or perform any provision of this
Section.

          (c) Tenant and the Tenant Entities will be entitled to the non-exclusive use of the common
areas of the Building as they exist from time to time during the Term, including the parking
facilities, subject to Landlord’s rules and regulations regarding such use. However, in no event
will Tenant or the Tenant Entities park more vehicles in the parking facilities than Tenant’s
Proportionate Share of the total parking spaces available for common use. The foregoing shall not
be deemed to provide Tenant with an exclusive right to any parking spaces or any guaranty of the
availability of any particular parking spaces or any specific number of parking spaces.”

     13. Indemnification. Section 10.1 “Tenant’s Indemnity” as stated in the Original
Lease shall be deleted in its entirety and the following substituted therefore:

          (a) None of the Landlord Entities shall be liable and Tenant hereby waives all claims against
them for any damage to any property or any injury to any person in or about the Premises or the
Building by or from any cause whatsoever (including without limiting the foregoing, rain or water
leakage of any character from the roof, windows, walls, basement, pipes, plumbing works or
appliances, the Building not being in good condition or repair, gas, fire, oil, electricity or
theft), except that such waiver shall not apply to the extent such claim is caused by or is arising
from the negligence or willful misconduct of Landlord or its agents, employees or contractors.
Tenant shall protect, indemnify and hold the Landlord Entities harmless from and against any and
all loss, claims, liability or costs (including court costs and attorney’s fees) incurred by reason
of (a) any damage to any property (including but not limited to property of any Landlord Entity) or
any injury (including but not limited to death) to any person occurring in, on or about the
Premises or the Building to the extent that such injury or damage shall be caused by or arise from
any actual or alleged act, neglect, fault, or omission by or of Tenant or any Tenant Entity to meet
any standards imposed by any duty with respect to the injury or damage; (b) the conduct or
management of any work or thing whatsoever done by the Tenant in or about the Premises or from
transactions of the Tenant concerning the Premises; (c) Tenant’s failure to comply with any and all
applicable governmental laws, ordinances and regulations applicable to the condition or use of the
Premises or its occupancy; or (d) any material breach or default on the part of Tenant in the
performance of any covenant or agreement on the part of the Tenant to be performed pursuant to this
Lease. The provisions of this Article shall survive the termination of this Lease with respect to
any claims or liability accruing prior to such termination.”

     14. Insurance. Section 10.2 “Tenant Insurance” as stated in the Original Lease shall
be deleted in its entirety and the following substituted therefor:

“Tenant shall keep in force throughout the Term: (a) a Commercial General Liability insurance
policy or policies to protect the Landlord Entities against any liability to the public or to any

 

 

invitee of Tenant or a Landlord Entity incidental to the use of or resulting from any accident
occurring in or upon the Premises with a limit of not less than $1,000,000 per occurrence and not
less than $2,000,000 in the annual aggregate, or such larger amount as Landlord may reasonably
require from time to time, covering bodily injury and property damage liability and $1,000,000
products/completed operations aggregate; (b) Business Auto Liability covering owned, non-owned and
hired vehicles with a limit of not less than $1,000,000 per accident; (c) Workers’ Compensation
Insurance with limits as required by statute and Employers Liability with limits of $500,000 each
accident, $500,000 disease policy limit, $500,000 disease--each employee; (d) All Risk or Special
Form coverage protecting Tenant against loss of or damage to Tenant’s alterations, additions,
improvements, carpeting, floor coverings, panelings, decorations, fixtures, inventory and other
business personal property situated in or about the Premises to the full replacement value of the
property so insured; and, (e) Business Interruption Insurance.

The aforesaid policies shall (a) be provided at Tenant’s expense; (b) be issued by an insurance
company with a minimum Best’s rating of 

“A-:VII” during the Term; and (c) provide that said
insurance shall not be canceled unless thirty (30) days prior written notice (ten days for
non-payment of premium) shall have been given to Landlord; a certificate of Liability insurance on
ACORD Form 25 or comparable alternate and a certificate of Property insurance on ACORD Form 28 or
comparable alternate shall be delivered to Landlord by Tenant upon the Commencement Date and at
least thirty (30) days prior to each renewal of said insurance.

Whenever Tenant shall undertake any alterations, additions or improvements in, to or about the
Premises (“Work”) the aforesaid insurance protection must extend to and include injuries to persons
and damage to property arising in connection with such Work, without limitation including liability
under any applicable structural work act, and such other insurance as Landlord shall require; and
the policies of or certificates evidencing such insurance must be delivered to Landlord prior to
the commencement of any such Work.”

     15. Tenant’s Authority (OFAC). If Tenant signs as a corporation, partnership, trust
or other legal entity each of the persons executing this Lease on behalf of Tenant represents and
warrants that Tenant has been and is qualified to do business in the state in which the Building is
located, that the entity 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, the International Emergency Economic Powers Act, 50
U.S.C. §§ 1701-06, the Patriot Act, Public Law 107-56, Executive Order 13224 (September 23, 2001)
or any Executive Order of the President issued 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.

 

 

     16. Renewal Option. Tenant shall, provided the Lease is in full force and effect and
Tenant is not in default under any of the other terms and conditions of the Lease at the time of
notification or commencement, have one (1) successive option to renew this Lease for a term of
three (3) years, for the portion of the Premises being leased by Tenant as of the date the renewal
term is to commence, on the same terms and conditions set forth in the Lease, except as modified by
the terms, covenants 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 increased 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. Said request shall be made no earlier than thirty (30) days
prior to the first date on which Tenant may exercise its option under this Paragraph. In no event
shall the 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.

     17. Right of First Offer. Provided Tenant is not then in default under the terms,
covenants and conditions of the Lease and subject to superior rights of other tenants of the
Building as of the execution of this Amendment, Tenant shall have the one-time right of first offer
to lease any space on the fourth and/or fifth floors of the Building (any such space, referred to
as an “Expansion Space”) at such time as an Expansion Space is vacated by the prior tenant and
Landlord proposes to offer such space to the public for lease. In such event, Landlord shall give
written notice to Tenant of the date of availability of the Expansion Space and the terms and
conditions on which Landlord intends to offer it to the public and Tenant shall have a period of
ten (10) business days in which to exercise Tenant’s right to lease the Expansion Space pursuant to
the terms and conditions contained in Landlord’s notice, failing which Landlord may lease the
Expansion Space to any third party on whatever basis Landlord desires, and Tenant shall have no
further rights with respect to that particular portion of the Expansion Space. Without limiting
the generality of the foregoing, if Landlord leases a particular Expansion Space to a third party
pursuant to the preceding sentence and such Expansion Space is subsequently vacated again during
the Term of this Lease or any renewal hereof, Tenant shall not have a new right of first offer to
lease such Space. If Tenant exercises its right to lease hereunder, effective as of the date
Landlord delivers the Expansion Space, the Expansion Space shall automatically be included within
the Premises and subject to all the terms and conditions of the Lease, except as set forth in
Landlord’s notice 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.

          (b) 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) Nothing herein shall be construed as to prohibit Landlord from extending the term of the
lease of any existing tenant.

          (f) 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.

     18. 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.

     19. Parking Garage. Section 2.2(c) of the Original Lease is modified as of the
Additional Space Commencement Date to change “One” to “Two” in the first line of the second
sentence thereof.

 

 

     20. 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.

(The remainder of this page is intentionally left blank.)

 

 

     21. Storage Space License. Effective as of the complete execution of this Amendment, the
Storage Space License, as attached to the Second Amendment, is modified by substituting “200
rentable square feet of storage space” for “400 rentable square feet of storage space” with a
License fee of $2,000.00 per annum, payable in equal monthly installments of $166.67 in lieu of
$4,000.00 per annum, payable in equal monthly installments of $333.33 as state therein.

     22. 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.

herein, each Revolving Credit Lender agrees to make Revolving Loans to the Borrower from time to
time during the Revolving Credit Availability Period in an aggregate principal amount that will not
result in such Lender’s Revolving Credit Exposure exceeding such Lender’s Revolving Credit
Commitment at such time; provided that the total Revolving Credit Exposure (after giving

Revolving Loans.

AutoBorrow Agreement; provided that (x) the aggregate amount of Revolving Loans made
in accordance with the terms of the AutoBorrow Agreement shall not exceed $10,000,000 at any
time and (y) Revolving Loans made to finance the reimbursement of an LC Disbursement shall

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

provided further that the Borrower shall use Swing Loan Borrowings to

would cause the aggregate principal balance of all Swing Loans outstanding to exceed the
Swing Loan Commitment, in which case the Borrower may use Base Rate Revolving Credit
Borrowings to finance such reimbursement, but only to the extent of such excess. Each such
telephonic Advance Request 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. Promptly

Loan to be made as part of the requested Borrowing, and provided that no Default under

therefrom, (i) in the case of a LIBOR Borrowing, on the date three Business Days after such
Advance Request is delivered to the Agent and (ii) in the case of a Base Rate Borrowing, on

          (c) Interest on Revolving Loans. Subject to Section 2.3 hereof, each Revolving Loan
made to the Borrower by the Lenders hereunder shall bear interest at a rate per annum equal to the
Base Rate plus the Applicable Margin; provided that all Revolving Loans made in accordance
with the AutoBorrow Agreement shall bear interest at a rate per annum equal to the Eurodollar Rate
applicable to Revolving Loans having an Interest Period of one month, plus the Applicable
Margin. Notwithstanding the foregoing, (i) all Revolving Loans which are not paid when due shall
automatically 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 (i) of Section 9.1 shall
have occurred and be continuing, the principal of all Revolving Loans hereunder shall automatically
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, the principal of all Revolving Loans hereunder
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. Except as otherwise provided in Section 2.3(b) hereof, accrued
interest on each Revolving Loan shall be payable in arrears on the first day of each month;
provided that interest accrued at the Post-Default Rate shall be payable on demand, and all
accrued interest on Revolving Loans shall be payable upon expiration of the Revolving Credit
Availability Period. All interest hereunder shall be

- 23 -

 

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.

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

promissory notes in such form payable to the order of the payee named therein.

          (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.

          (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

grant of a security interest pursuant to this Agreement and the other Loan Documents (i) would
invalidate the underlying rights of such Credit Party under such license or lease, (ii) is
prohibited by such license or lease, without the consent of any other party thereto, (iii) would

Collateral shall include, and the Credit Party shall be deemed to have granted a security interest
in, any of such Credit Party’s rights, interests, licenses or leases and any other rights and
assets that would not constitute Collateral if the foregoing provisions of this sentence governed,
if and to the extent that the issuer of or other party to such license or lease has consented to
such grant or to the extent that any term of any such rights, interests, licenses or leases would
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
prudent and commercially reasonable business practices, the Credit Parties shall not abandon any
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
all other relevant information pertaining to such domain names, and the administrative contacts
used in connection with the registration of such domain names are identified on Schedule
4.2 hereof. No Credit Party will change such domain name servers without 10 days’ prior notice
to the

 - 48 - 

 

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
entered into by any Credit Party in the ordinary course of such Credit Party’s business) in an
amount equal to or greater than $100,000, such Credit Party will promptly notify the Lender thereof
and, at the request and option of the Lender, such Debtor will deliver such promissory note or
other instrument or tangible chattel paper to the Lender to be held as Collateral hereunder,
together with an endorsement thereof reasonably satisfactory in form and substance to the Lender.

          (m) If, now or at any time hereafter, any Credit Party shall obtain or hold any investment
property or electronic chattel paper in an amount equal to or greater than $100,000, such Credit
Party will promptly notify the Lender thereof and, at the request and option of the Lender, such
Credit Party will take or cause to be taken such steps as the Lender may reasonably request for the
Lender to obtain “control” (as provided in Sections 9-105 and 9-106 of the Uniform Commercial Code
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,
of the Credit Parties (taken as a whole) from that set forth in the December 31, 2007 financial
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
statements in accordance with GAAP, except (i) as referred to or reflected or provided for in the
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
the Credit Parties material to their business is in good operating condition and repair (ordinary
wear and tear excepted), and all necessary replacements of and repairs thereto have be made so as
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.

renewals or extensions of any thereof) affecting each Leasehold Property, regardless of whether
such Credit Party is the landlord or tenant (whether directly or as an assignee or successor in
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).

          (b) Except for the Disclosed Matters set forth in Schedule 5.6 and except with respect
to any other matters that, individually or in the aggregate, could not reasonably be expected to
result in a Material Adverse Effect, the Credit Parties (i) have not failed to comply with any
Environmental Law or to obtain, maintain or comply with any permit, license or other approval
required in connection with the operation of the Credit Parties’ business to be in compliance with
all applicable Environmental Laws, (ii) have not become subject to any Environmental Liability;

likelihood of, a Material Adverse Effect.

Credit Party is in compliance with all laws, regulations, policies and orders of any Governmental
Authority applicable to it or its property and all indentures, agreements and other instruments
binding upon it or its property, except where the failure to do so, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse Effect.

adequate reserves with

 - 53 - 

 

respect thereto in accordance with GAAP, which reserves shall be acceptable to Agent, or (b)
to the extent that the failure to do so could not reasonably be expected to result in a Material
Adverse Effect.

     5.10 ERISA. Except as set forth on Schedule 5.10, no Credit Party has any Pension
Plans. No ERISA Event has occurred or is reasonably expected to occur that, when taken together
with all other such ERISA Events for which liability is reasonably expected to occur, could

intention to terminate any Pension Plan with respect to which any Credit Party would incur a cost
of more than $100,000 to terminate such Plan, including amounts required to be contributed to fund
such Plan on Plan termination and all costs and expenses associated therewith, including without
limitation attorneys’ and actuaries’ fees and expenses in connection with such termination and a
reasonable estimate of expenses and settlement or judgment costs and attorneys’ fees and expenses
in connection with litigation related to such termination.

     5.11 Disclosure. As of the Effective Time, the Credit Parties have disclosed to the Agent all

value on a consolidated, going concern basis (i.e., 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 that could be obtained for such

contracts, each account receivable is for a liquidated amount maturing as stated in the duplicate
invoice covering such sale or rendition of services, a copy of which has been furnished or is

offset, Lien, deduction, defense, dispute, counterclaim or any other adverse condition except for
disputes resulting in returned goods where the amount in controversy is deemed by the Agent to be
immaterial and Liens arising in the ordinary course of business under applicable law in favor of
subcontractors, materialmen and mechanics in respect of work performed in connection with such
account receivable; provided that the Credit Parties shall pay all amounts required to be
paid to any such subcontractor, materialman or mechanic in accordance with the terms of the
agreement relating to such account receiveable;

of each respective invoice related thereto;

          (f) To the best knowledge of the Credit Parties, the account debtor under each account
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

          (g) To the best knowledge of the Credit Parties, there are no proceedings or actions which are
threatened or pending against any account debtor which might result in any material adverse change
in such account debtor’s financial condition or the collectability of any account receivable.

payable in whole (or in part, in which case any principal not so declared to be due and payable may

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

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.

prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received
upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return
receipt requested” function, as available, return e-mail or other written acknowledgement),
provided that if such notice or other communication is not sent during the normal business hours of
the recipient, such notice or communication shall be deemed to have been sent at the opening of
business on the next business day for the recipient, and (ii) notices or communications posted to
an Internet or intranet website shall be deemed received upon the deemed receipt by the intended
recipient at its e-mail address as described in the foregoing clause (i) of notification that such
notice or communication is available and identifying the website address therefor.

          (c) The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT
PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF BORROWER MATERIALS OR THE
ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM BORROWER
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
communications hereunder by notice to the other parties hereto. Each other Lender may change its
address, telecopier or telephone number for notices and other communications hereunder by notice to
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.
Furthermore, each Public Lender agrees to cause at least one individual at or on behalf of such
Public Lender to at all times have selected the “Private Side Information” or similar designation
on the content declaration screen of the Platform in order to enable such Public Lender or its
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
that are not made available through the “Public Side Information” portion of the Platform and that
may contain material non-public information with respect to the Borrower or its securities for
purposes of United States Federal or state securities laws.

          (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
