LOAN AND SECURITY AGREEMENT

     THIS LOAN AND SECURITY AGREEMENT (this “Agreement”) dated as of the Effective Date between
SILICON VALLEY BANK, a California corporation with a loan production office located at 275 Grove
Street, Suite 2-200, Newton, Massachusetts 02466 (“Bank”), and ASPEN AEROGELS, INC., a Delaware
corporation with offices located at 30 Forbes Road, Building B, Northborough, Massachusetts 01532
(“Borrower”), provides the terms on which Bank shall lend to Borrower and Borrower shall repay
Bank. The parties agree as follows:

     1 ACCOUNTING AND OTHER TERMS

     Accounting terms not defined in this Agreement shall be construed following GAAP.
Calculations and determinations must be made following GAAP. Capitalized terms not otherwise
defined in this Agreement shall have the meanings set forth in Section 13. All other terms
contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the
Code to the extent such terms are defined therein.

     2 LOAN AND TERMS OF PAYMENT

     2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding
principal amount of all Credit Extensions and accrued and unpaid interest thereon as and when due
in accordance with this Agreement.

     2.1.1 Revolving Advances.

          (a) Availability. Subject to the terms and conditions of this Agreement and to
deduction of Reserves, following the Account Transition Period, Bank shall make Advances not
exceeding the Availability Amount. Amounts borrowed under the Revolving Line may be repaid, and
prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and
conditions precedent herein.

          (b) Termination; Repayment. The Revolving Line terminates on the Revolving Line
Maturity Date, when the principal amount of all Advances, the unpaid interest thereon, and all
other Obligations relating to the Revolving Line shall be immediately due and payable.

     2.1.2 Letters of Credit Sublimit.

          (a) As part of the Revolving Line and subject to deduction of Reserves, following the Account
Transition Period, Bank shall issue or have issued Letters of Credit denominated in Dollars or a
Foreign Currency for Borrower’s account. The aggregate Dollar Equivalent amount utilized for the
issuance of Letters of Credit shall at all times reduce the amount otherwise available for Advances
under the Revolving Line. The aggregate Dollar Equivalent of the face amount of outstanding
Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit
Reserve) may not exceed the lesser of (A) Two Million Dollars ($2,000,000), minus (i) the
sum of all amounts used for Cash Management Services, and minus (ii) the FX Reduction
Amount, or (B) the lesser of Revolving Line or the Borrowing Base, minus (i) the sum of all
outstanding principal amounts of any Advances (including any amounts used for Cash Management
Services), and minus (ii) the FX Reduction Amount.

          (b) If, on the Revolving Line Maturity Date (or the effective date of any termination of this
Agreement), there are any outstanding Letters of Credit, then on such date Borrower shall provide
to Bank cash collateral in an amount equal to 105% of the Dollar Equivalent of the face amount of
all such Letters of Credit plus all interest, fees, and costs due or to become due in connection
therewith (as estimated by Bank in its good faith business judgment), to secure all of the
Obligations relating to such Letters of Credit. All Letters of Credit shall be in form and
substance acceptable to Bank in its sole discretion and shall be subject to the terms and
conditions of Bank’s standard Application and Letter of Credit Agreement (the “Letter of Credit
Application”). Borrower agrees to execute any further documentation in connection with the Letters
of Credit as Bank may reasonably request. Borrower further agrees to be bound by the regulations
and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for
Borrower’s account or by Bank’s interpretations of any Letter of Credit issued by Bank for
Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any
error, negligence, or mistake, whether of omission or commission, in following Borrower’s
instructions or those contained in the Letters of Credit or any modifications, amendments, or
supplements thereto.

 

 

          (c) The obligation of Borrower to immediately reimburse Bank for drawings made under Letters
of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement, such Letters of Credit, and the Letter of Credit
Application.

          (d) Borrower may request that Bank issue a Letter of Credit payable in a Foreign Currency. If
a demand for payment is made under any such Letter of Credit, Bank shall treat such demand as an
Advance to Borrower of the Dollar Equivalent of the amount thereof (plus fees and charges in
connection therewith such as wire, cable, SWIFT or similar charges).

          (e) To guard against fluctuations in currency exchange rates, upon the issuance of any Letter
of Credit payable in a Foreign Currency, Bank shall create a reserve (the “Letter of Credit
Reserve”) under the Revolving Line in an amount equal to ten percent (10%) of the face amount of
such Letter of Credit. The amount of the Letter of Credit Reserve may be adjusted by Bank from
time to time to account for fluctuations in the exchange rate. The availability of funds under the
Revolving Line shall be reduced by the amount of such Letter of Credit Reserve for as long as such
Letter of Credit remains outstanding.

     2.1.3 Foreign Exchange Sublimit. As part of the Revolving Line and subject to the deduction
of Reserves, following the Account Transition Period, Borrower may enter into foreign exchange
contracts with Bank under which Borrower commits to purchase from or sell to Bank a specific amount
of Foreign Currency (each, a “FX Forward Contract”) on a specified date (the “Settlement Date”).
FX Forward Contracts shall have a Settlement Date of at least one (1) FX Business Day after the
contract date. The aggregate amount of FX Forward Contracts at any one time may not exceed ten
(10) times the lesser of (A) Two Million Dollars ($2,000,000), minus (i) the sum of all
amounts used for Cash Management Services, and minus (ii) the Dollar Equivalent of the face
amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and
any Letter of Credit Reserve), or (B) the lesser of Revolving Line or the Borrowing Base,
minus (i) the sum of all outstanding principal amounts of any Advances (including any
amounts used for Cash Management Services), and minus (ii) the Dollar Equivalent of the
face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of
Credit and any Letter of Credit Reserve). The amount otherwise available for Credit Extensions
under the Revolving Line shall be reduced by an amount equal to ten percent (10%) of each
outstanding FX Forward Contract (the “FX Reduction Amount”). Any amounts needed to fully reimburse
Bank for any amounts not paid by Borrower in connection with FX Forward Contracts will be treated
as Advances under the Revolving Line and will accrue interest at the interest rate applicable to
Advances.

     2.1.4 Cash Management Services Sublimit. Borrower may, following the Account Transition
Period, use the Revolving Line for Bank’s cash management services, which may include merchant
services, direct deposit of payroll, business credit card, and check cashing services identified in
Bank’s various cash management services agreements (collectively, the “Cash Management Services”),
in an aggregate amount not to exceed the lesser of (A) Two Million Dollars ($2,000,000),
minus (i) the Dollar Equivalent of the face amount of any outstanding Letters of Credit
(including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), and
minus (ii) the FX Reduction Amount, or (B) the lesser of Revolving Line or the Borrowing
Base, minus (i) the sum of all outstanding principal amounts of any Advances, minus
(ii) the Dollar Equivalent of the face amount of any outstanding Letters of Credit (including drawn
but unreimbursed Letters of Credit and any Letter of Credit Reserve), and minus (iii) the
FX Reduction Amount. Any amounts Bank pays on behalf of Borrower for any Cash Management Services
will be treated as Advances under the Revolving Line and will accrue interest at the interest rate
applicable to Advances.

     2.2 Overadvances. If, at any time, the sum of (a) the outstanding principal amount of any
Advances (including any amounts used for Cash Management Services and the outstanding principal
amount of any EXIM Loans); plus (b) the face amount of any outstanding Letters of Credit
(including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve); plus
(c) the FX Reduction Amount exceeds the lesser of either the Revolving Line or the Borrowing Base
(such excess amount being an “Overadvance”), Borrower shall immediately pay to Bank in cash such
Overadvance. Without limiting Borrower’s obligation to repay Bank any amount of the Overadvance,
Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance, on demand, at
the Default Rate.

     2.3 Payment of Interest on the Credit Extensions.

          (a) Interest Rate; Advances. Subject to Section 2.3(b), the principal amount
outstanding under the Revolving Line shall accrue interest at a floating per annum rate equal to
Prime Rate plus one percent (1.00%); provided, however, when Borrower is at or
above the Liquidity Threshold, the principal amount

-2-

 

outstanding under the Revolving Line shall
accrue interest at a floating per annum rate equal to the Prime Rate plus
one-half percent (0.50%). Such interest shall in any event be payable monthly, in arrears, in
accordance with Section 2.3(f) below.

          (b) Default Rate. Immediately upon the occurrence and during the continuance of an
Event of Default, Obligations shall bear interest at a rate per annum which is four percentage
points (4.00%) above the rate that is otherwise applicable thereto (the “Default Rate”) unless Bank
otherwise elects from time to time in its sole discretion to impose a smaller increase. Fees and
expenses which are required to be paid by Borrower pursuant to the Loan Documents (including,
without limitation, Bank Expenses) but are not paid when due shall bear interest until paid at a
rate equal to the highest rate applicable to the Obligations. Payment or acceptance of the
increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely
payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit
any rights or remedies of Bank.

          (c) Adjustment to Interest Rate. Changes to the interest rate of any Credit Extension
based on changes to the Prime Rate shall be effective on the effective date of any change to the
Prime Rate and to the extent of any such change.

          (d) Computation; 360-Day Year. In computing interest, the date of the making of any
Credit Extension shall be included and the date of payment shall be excluded; provided, however,
that if any Credit Extension is repaid on the same day on which it is made, such day shall be
included in computing interest on such Credit Extension. Interest shall be computed on the basis
of a 360-day year for the actual number of days elapsed.

          (e) Debit of Accounts. Bank may debit any of Borrower’s deposit accounts, including
the Designated Deposit Account, for principal and interest payments or any other amounts Borrower
owes Bank when due. These debits shall not constitute a set-off.

          (f) Payment; Interest Computation; Float Charge. Interest is payable monthly on the
last calendar day of each month. In computing interest on the Obligations, all Payments received
after 12:00 noon Eastern time on any day shall be deemed received on the next Business Day. In
addition, Bank shall be entitled to charge Borrower a “float” charge in an amount equal to three
(3) Business Days interest, at the interest rate applicable to the Advances, on all Payments
received by Bank; provided, that when Borrower is at or above the Liquidity
Threshold, such “float” charge shall not apply. The float charge for each month shall be payable
on the last day of the month. Bank shall not, however, be required to credit Borrower’s account
for the amount of any item of payment which is unsatisfactory to Bank in its good faith business
judgment, and Bank may charge Borrower’s Designated Deposit Account for the amount of any item of
payment which is returned to Bank unpaid.

     2.4 Fees. Borrower shall pay to Bank:

          (a) Commitment Fee. A fully earned, non refundable commitment fee of Seventy Five
Thousand Dollars ($75,000), payable on the Effective Date;

          (b) Anniversary Fee. A fully earned, non refundable anniversary fee of Twenty Seven
Thousand Five Hundred Dollars ($27,500), payable on the date that is three hundred sixty five (365)
days after the Effective Date

          (c) Letter of Credit Fee. Bank’s customary fees and expenses for the issuance or
renewal of Letters of Credit, (including, without limitation, a letter of credit fee of two percent
(2.00%) per annum of the Dollar Equivalent of the face amount of each Letter of Credit issued),
upon the issuance of such Letter of Credit, each anniversary of the issuance during the term of
such Letter of Credit, and upon the renewal of such Letter of Credit by Bank;

          (d) Unused Revolving Line Facility Fee. A fee (the “Unused Revolving Line Facility
Fee”), payable quarterly, in arrears, following the Account Transition Period, in an amount equal
to one-half percent (0.50%) per annum of the average unused portion of the Revolving Line. The
unused portion of the Revolving Line, for purposes of this calculation, shall equal the difference
between (x) the Revolving Line amount (as it may be reduced from time to time) and (y) the average
for the period of the daily closing balance of the Revolving Line outstanding plus the sum of the
aggregate amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of
Credit and any Letter of Credit Reserve, plus the sum of any Reserves). Borrower shall not be
entitled to any credit, rebate or repayment of any Unused Revolving Line Facility Fee previously
earned by Bank

-3-

 

pursuant to this Section notwithstanding any termination of the Agreement or the
suspension or termination of Bank’s obligation to make loans and advances hereunder; and

          (e) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and
expenses for documentation and negotiation of this Agreement) incurred through and after the
Effective Date, when due.

     2.5 Payments; Application of Payments.

          (a) All payments (including prepayments) to be made by Borrower under any Loan Document shall
be made in immediately available funds in U.S. Dollars, without setoff or counterclaim, before
12:00 noon Eastern time on the date when due. Payments of principal and/or interest received after
12:00 noon Eastern time are considered received at the opening of business on the next Business
Day. When a payment is due on a day that is not a Business Day, the payment shall be due the next
Business Day, and additional fees or interest, as applicable, shall continue to accrue until paid.

          (b) Subject to Section 6.3(c), Bank shall apply the whole or any part of collected funds
against the Revolving Line or credit such collected funds to a depository account of Borrower with
Bank (or an account maintained by an Affiliate of Bank), the order and method of such application
to be in the sole discretion of Bank. Borrower shall have no right to specify the order or the
accounts to which Bank shall allocate or apply any payments required to be made by Borrower to Bank
or otherwise received by Bank under this Agreement when any such allocation or application is not
specified elsewhere in this Agreement.

Report;

          (b) the representations and warranties in this Agreement shall be true, accurate, and complete
in all material respects on the date of the Transaction Report and on the Funding Date of each

materiality in the text thereof; and provided, further that those representations
and warranties expressly referring to a specific date shall be true, accurate and complete in all
material respects as of such date, and no Default or Event of Default shall have occurred and be

Responsible Officer or his or her designee. Bank may rely on any telephone notice given by a
person whom Bank believes is a Responsible Officer or designee. Bank shall credit Advances to the
Designated Deposit Account. Bank may make Advances under this Agreement based on instructions from
a Responsible Officer or his or her designee or without instructions if the Advances are necessary
to meet Obligations which have become due.

     4 CREATION OF SECURITY INTEREST

     4.1 Grant of Security Interest. Borrower hereby grants Bank, to secure the payment
and performance in full of all of the Obligations, a continuing security interest in, and pledges
to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and
all proceeds and products thereof.

     4.2 Priority of Security Interest. Borrower represents, warrants, and covenants that the
security interest granted herein is and shall at all times continue to be a first priority
perfected security interest in the Collateral (subject only to Permitted Liens that may have
superior priority to Bank’s Lien under this Agreement or the Export-Import Agreement). If Borrower
shall acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing signed by
Borrower of the general details thereof and grant to Bank 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 Bank.

          If this Agreement is terminated, Bank’s Lien in the Collateral shall continue until the
Obligations (other than inchoate indemnity obligations) are repaid in full in cash. Upon payment
in full in cash of the Obligations and at such time as Bank’s obligation to make Credit Extensions
has terminated, Bank shall, at Borrower’s sole cost and expense, release its Liens in the
Collateral and all rights therein shall revert to Borrower.

          Notwithstanding the foregoing, it is expressly acknowledged and agreed that the security
interest created in this Agreement only with respect to Export-Related Accounts Receivable,
Export-Related Inventory and Export-Related General Intangibles (as such terms are defined in the
Export-Import Agreement) is subject to and subordinate to the security interest granted to Bank in
the Export-Import Agreement with respect to such Export-Related Accounts Receivable, Export-Related
Inventory and Export-Related General Intangibles.

     4.3 Authorization to File Financing Statements. Borrower hereby authorizes Bank to file
financing statements, without notice to Borrower, with all appropriate jurisdictions to perfect or
protect Bank’s interest or rights hereunder, including a notice that any disposition of the
Collateral, by either Borrower or any other Person not in accordance with this Agreement, may be
deemed to violate the rights of Bank under the Code.

     5 REPRESENTATIONS AND WARRANTIES

          Borrower represents and warrants as follows:

     5.1 Due Organization; Authorization; Power and Authority. Borrower and each of its
Subsidiaries are duly existing and in good standing as a Registered Organization in its
jurisdiction of formation and each is qualified and licensed to do business and each is in good
standing in any jurisdiction in which the conduct of each of its business or its ownership of
property requires that it be qualified except where the failure to do so could not reasonably be
expected to have a material adverse effect on Borrower’s business. In connection with this
Agreement, Borrower has delivered to Bank completed certificates each signed by Borrower and
Guarantor, respectively, entitled “Perfection Certificate”. Borrower represents and warrants to
Bank that (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on
the signature page hereof; (b) Borrower is an organization of the type and is organized in the
jurisdiction set forth in the Perfection Certificate; (c) the Perfection Certificate accurately
sets forth Borrower’s organizational identification number or accurately states that Borrower has
none; (d) the Perfection Certificate accurately sets forth Borrower’s place of business, or, if
more than one, its chief executive office as well as Borrower’s mailing address (if different than
its chief executive office); (e) except as set forth on the Perfection Certificate, Borrower (and
each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of
formation, organizational structure or type, or any organizational number assigned by its
jurisdiction; and (f) all other information set forth on the Perfection Certificate pertaining to
Borrower and each of its Subsidiaries is accurate and complete (it being understood and agreed that
Borrower may from time to time update certain information in the Perfection Certificate after the
Effective Date to the extent permitted by one or more specific provisions in this Agreement). If
Borrower is not now a Registered Organization but later becomes one, Borrower shall promptly notify
Bank of such occurrence and provide Bank with Borrower’s organizational identification number.

     The execution, delivery and performance by Borrower of the Loan Documents to which it is a
party have been duly authorized, and do not (i) conflict with any of Borrower’s organizational
documents, (ii) contravene, conflict with, constitute a default under or violate any material
Requirement of Law, (iii) contravene, conflict or violate any applicable order, writ, judgment,
injunction, decree, determination or award of any Governmental Authority by which Borrower or any
of its Subsidiaries or any of their property or assets may be bound or affected, (iv) require any
action by, filing, registration, or qualification with, or Governmental Approval from, any

-6-

 

Governmental Authority (except such Governmental Approvals which have already been obtained and are
in full force and effect) or (v) constitute an event of default under any material agreement by
which Borrower is bound. Borrower is not in default under any agreement to which it is a party or
by which it is bound in which the default could reasonably be expected to have a material adverse
effect on Borrower’s business.

     5.2 Collateral. Borrower has good title to, has rights in, and the power to transfer each
item of the Collateral upon which it purports to grant a Lien hereunder, free and clear of any and
all Liens except Permitted Liens. Borrower has no deposit accounts other than the deposit accounts
with Bank, the deposit accounts, if any described in the Perfection Certificate delivered to Bank
in connection herewith, or of which Borrower has given Bank notice and taken such actions as are
necessary to give Bank a perfected security interest therein. The Accounts are bona fide, existing
obligations of the Account Debtors.

          The Collateral is not in the possession of any third party bailee (such as a warehouse) except
as otherwise provided in the Perfection Certificate. None of the components of the Collateral
shall be maintained at locations other than as provided in the Perfection Certificate or as
permitted pursuant to Section 7.2. In the event that Borrower, after the date hereof, intends to
store or otherwise deliver any portion of the Collateral to a bailee, then Borrower will first
receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in
form and substance satisfactory to Bank in its sole discretion.

          All Inventory is in all material respects of good and marketable quality, free from material
defects, except normal and customary quality issues occurring in the ordinary course of business,
in amounts consistent with past practices.

          Borrower is the sole owner of the Intellectual Property which it owns or purports to own
except for (a) non-exclusive licenses granted to its customers in the ordinary course of business,
(b) over-the-counter software that is commercially available to the public, and (c) material
Intellectual Property licensed to Borrower and noted on the Perfection Certificate. Each Patent
which it owns or purports to own and which is material to Borrower’s business is valid and
enforceable, and no part of the Intellectual Property which Borrower owns or purports to own and
which is material to Borrower’s business has been judged invalid or unenforceable, in whole or in
part, except to the extent in each of the above such invalidity or unenforceability would not have
a material adverse effect on Borrower’s business, taken as a whole. To the best of Borrower’s
knowledge, no claim has been made that any part of the Intellectual Property violates the rights of
any third party except to the extent such claim would not have a material adverse effect on
Borrower’s business, taken as a whole.

     5.3 Accounts Receivable; Inventory. For any Eligible Account in any Borrowing Base
Certificate, all statements made and all unpaid balances appearing in all invoices, instruments and
other documents evidencing such Eligible Accounts are and shall be true and correct and all such
invoices, instruments and other documents, and all of Borrower’s Books are genuine and in all
respects what they purport to be. Whether or not an Event of Default has occurred and is
continuing, Bank may, after consultation with Borrower, notify any Account Debtor owing Borrower
money of Bank’s security interest in such funds and verify the amount of such Eligible Account.
All sales and other transactions underlying or giving rise to each Eligible Account shall comply in
all material respects with all applicable laws and governmental rules and regulations. Borrower
has no knowledge of any actual or imminent Insolvency Proceeding of any Account Debtor whose
accounts are Eligible Accounts in any Borrowing Base Certificate. To the best of Borrower’s
knowledge, all signatures and endorsements on all documents, instruments, and agreements relating
to all Eligible Accounts are genuine, and all such documents, instruments and agreements are
legally enforceable in accordance with their terms.

     5.4 Litigation. There are no actions or proceedings pending or, to the knowledge of the
Responsible Officers, threatened in writing by or against Borrower or any of its Subsidiaries
involving more than, individually or in the aggregate, One Hundred Fifty Thousand Dollars
($150,000).

     5.5 Financial Condition. All consolidated financial statements for Borrower delivered to Bank
fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s
consolidated results of operations. There has not been any material deterioration in Borrower’s
consolidated financial condition since the date of the most recent financial statements submitted
to Bank.

     5.6 Solvency. The fair salable value of Borrower’s assets (including goodwill minus
disposition costs) exceeds the fair value of its liabilities; Borrower is not left with
unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay
its debts (including trade debts) as they mature.

-7-

 

     5.7 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled”
by an “investment company” under the Investment Company Act of 1940, as amended. Borrower is not
engaged as one of its important activities in extending credit for margin stock (under Regulations
X, T and U of the Federal Reserve Board of Governors). Borrower has complied in all material
respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries
is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company” of a
“holding company” as each term is defined and used in the Public Utility Holding
Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation
of which could reasonably be expected to have a material adverse effect on its business. Except as
described in the Perfection Certificate or otherwise disclosed to Bank, none of Borrower’s or any
of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the
best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or
transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries
have obtained all consents, approvals and authorizations of, made all declarations or filings with,
and given all notices to, all Governmental Authorities that are necessary to continue their
respective businesses as currently conducted, the absence of which could reasonably be expected to
have a materially adverse effect on the Borrower.

     5.8 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other
equity securities except for Permitted Investments.

     5.9 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required
tax returns and reports, and Borrower has timely paid all foreign, federal, state and local taxes,
assessments, deposits and contributions owed by Borrower. Borrower may defer payment of any
contested taxes, provided that Borrower (a) in good faith contests its obligation to pay the taxes
by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in
writing of the commencement of, and any material development in, the proceedings, (c) posts bonds
or takes any other steps required to prevent the Governmental Authority levying such contested
taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”.
Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years
which could result in additional taxes becoming due and payable by Borrower. Borrower has paid all
amounts necessary to fund all present pension, profit sharing and deferred compensation plans in
accordance with their terms, and Borrower has not withdrawn from participation in, and has not
permitted partial or complete termination of, or permitted the occurrence of any other event with
respect to, any such plan which could reasonably be expected to result in any liability of
Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or
any other governmental agency.

     5.10 Use of Proceeds. Borrower shall use the proceeds of the Credit Extensions solely as
working capital to fund its general business requirements and not for personal, family, household
or agricultural purposes.

     5.11 Full Disclosure. No written representation, warranty or other statement of Borrower in
any certificate or written statement given to Bank, as of the date such representation, warranty,
or other statement was made, taken together with all such written certificates and written
statements given to Bank, contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained in the certificates or statements not
misleading (it being recognized by Bank that the projections and forecasts provided by Borrower in
good faith and based upon reasonable assumptions are not viewed as facts and that actual results
during the period or periods covered by such projections and forecasts may differ from the
projected or forecasted results).

     5.12 Definition of “Knowledge.” For purposes of the Loan Documents, whenever a representation
or warranty is made to Borrower’s knowledge or awareness, to the “best of” Borrower’s knowledge, or
with a similar qualification, knowledge or awareness means the actual knowledge, after reasonable
investigation, of the Responsible Officers.

     6 AFFIRMATIVE COVENANTS

          Borrower shall do all of the following:

     6.1 Government Compliance. (a) Maintain its and all its Subsidiaries’ legal existence and
good standing in their respective jurisdictions of formation and maintain qualification in each

adverse effect on Borrower’s business or operations. Borrower shall comply, and have each
Subsidiary comply, with all laws, ordinances and regulations to which it is subject, the
noncompliance with which could have a material adverse effect on Borrower’s business.

more;

days after the end of each month.

          (c) Borrower shall provide Bank with prompt written notice of Borrower’s knowledge of an event
that affects the value of the Intellectual Property and that would have a material adverse effect
on Borrower’s business, taken as a whole.

     6.3 Accounts Receivable.

          (a) Schedules and Documents Relating to Accounts. Borrower shall deliver to Bank
transaction reports and schedules of collections, as provided in Section 6.2, on Bank’s standard
forms; provided, however, that Borrower’s failure to execute and deliver the same
shall not affect or limit Bank’s Lien and other rights in all of Borrower’s Accounts, nor shall
Bank’s failure to advance or lend against a specific Account affect or limit Bank’s Lien and other
rights therein. If requested by Bank, Borrower shall furnish Bank with copies (or, at Bank’s
request after the occurrence and during the continuance of an Event of Default, originals) of all
contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery
receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of
which gave rise to such Accounts. In addition, Borrower shall deliver to Bank, on its request, the
originals of all instruments, chattel paper, security agreements, guarantees and other documents
and property evidencing or securing any Accounts, in the same form as received, with all necessary
endorsements, and copies of all credit memos.

          (b) Disputes. Borrower shall promptly notify Bank of all disputes or claims relating
to Accounts, to the extent such disputes or claims involve amounts in excess of Two Hundred Fifty
Thousand Dollars ($250,000) in the aggregate for all Account Debtors. Borrower may forgive
(completely or partially), compromise, or settle any Account for less than payment in full, or
agree to do any of the foregoing so long as (i) Borrower does so in good faith, in a commercially
reasonable manner, in the ordinary course of business, in arm’s-length transactions, and reports
the same to Bank in the regular reports provided to Bank; (ii) no Default or Event of Default has
occurred and is continuing; and (iii) after taking into account all such discounts, settlements and
forgiveness, the total outstanding Advances will not exceed the Availability Amount.

          (c) Collection of Accounts. Borrower shall have the right to collect all Accounts,
unless and until a Default or an Event of Default has occurred and is continuing. All payments on,
and proceeds of, Accounts shall be deposited directly by the applicable Account Debtor into a
lockbox account, or such other “blocked account” as Bank may specify, pursuant to a blocked account
agreement in form and substance satisfactory to Bank in its sole discretion. Whether or not an
Event of Default has occurred and is continuing, Borrower shall immediately deliver all payments on
and proceeds of Accounts to an account maintained with Bank to be applied (i) prior to an Event of
Default, to the Revolving Line pursuant to the terms of Section 2.5(b) hereof, and (ii) after the
occurrence and during the continuance of an Event of Default, pursuant to the terms of Section 9.4
hereof; provided, however, when Borrower is at or above the Liquidity Threshold,
such payments and proceeds shall be transferred to an account of Borrower maintained at Bank.

          (d) Returns. Provided no Event of Default has occurred and is continuing, if any
Account Debtor returns any Inventory having an aggregate value in excess of Two Hundred Fifty
Thousand Dollars ($250,000) to Borrower, Borrower shall promptly (i) determine the reason for such
return, (ii) issue a credit memorandum to the Account Debtor in the appropriate amount, and (iii)
provide a copy of such credit memorandum to Bank, upon request from Bank. In the event any
attempted return occurs after the occurrence and during the continuance of any Event of Default,
Borrower shall immediately notify Bank of the return of the Inventory.

          (e) Verification. Bank may, from time to time, after consultation with Borrower,
verify directly with the respective Account Debtors the validity, amount and other matters relating
to the Accounts, either in the name of Borrower or Bank or such other name as Bank may choose.

          (f) No Liability. Bank shall not be responsible or liable for any shortage or
discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of
which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any Account, or for settling
any Account in good faith for less than the full amount thereof, nor shall Bank be deemed to be
responsible for any of Borrower’s obligations under any contract or agreement giving rise to an
Account. Nothing herein shall, however, relieve Bank from liability for its own gross negligence
or willful misconduct.

     6.4 Remittance of Proceeds. Except as otherwise provided in Section 6.3(c), deliver, in kind,
all proceeds arising from the disposition of any Collateral to Bank in the original form in which
received by Borrower

-10-

 

not later than the following Business Day after receipt by Borrower, to be
applied to the Obligations (1) prior to an Event of Default, pursuant to the terms of Section
2.5(b) hereof, and (2) after the occurrence and during the continuance of an Event of Default,
pursuant to the terms of Section 9.4 hereof; provided that, if no Event of Default
has occurred and is continuing, Borrower shall not be obligated to remit to Bank the proceeds of
the sale of surplus, worn out or obsolete Equipment disposed of by Borrower in good faith in an
arm’s length transaction for an aggregate purchase price of Five Hundred Thousand Dollars
($500,000) or less (for all such transactions in any fiscal year). Borrower agrees that it will
maintain all proceeds of Collateral in an account maintained with Bank. Nothing in this Section
limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement.

     6.5 Taxes; Pensions; Withholding. Timely file, and require each of its Subsidiaries to timely
file, all required tax returns and reports and timely pay, and require each of its Subsidiaries to
timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions
owed by Borrower and each of its Subsidiaries, except for deferred payment of any taxes contested
pursuant to the terms of Section 5.9 hereof, and shall deliver to Bank, on demand, appropriate
certificates attesting to such payments, and pay all amounts necessary to fund all present pension,
profit sharing and deferred compensation plans in accordance with their terms.

     6.6 Access to Collateral; Books and Records. In addition to the Initial Audit, at reasonable
times, on one (1) Business Day’s notice (provided no notice is required if an Event of Default has
occurred and is continuing), Bank, or its agents, shall have the right, up to two (2) times per
year (or more frequently (i) after the occurrence and during the continuance of an Event of
Default, as Bank shall determine necessary, or (ii) at the direction of EXIM Bank), to inspect the
Collateral and the right to audit and copy Borrower’s Books. The foregoing inspections and audits
shall be at Borrower’s expense, and the charge therefor shall be $850 per person per day (or such
higher amount as shall represent Bank’s then-current standard charge for the same), plus reasonable
out-of-pocket expenses. In the event Borrower and Bank schedule an audit more than ten (10) days
in advance, and Borrower cancels or seeks to reschedule the audit with less than ten (10) days
written notice to Bank, then (without limiting any of Bank’s rights or remedies), Borrower shall
pay Bank a fee of $1,000 plus any out-of-pocket expenses incurred by Bank to compensate Bank for
the anticipated costs and expenses of the cancellation or rescheduling.

     6.7 Insurance. Keep its business and the Collateral insured for risks and in amounts standard
for companies in Borrower’s industry and location and as Bank may reasonably request. Insurance
policies shall be in a form, with companies, and in amounts that are satisfactory to Bank. All
property policies shall have a lender’s loss payable endorsement showing Bank as an additional
lender loss payee and waive subrogation against Bank. All liability policies shall show, or have
endorsements showing, Bank as an additional insured. All policies (or their respective
endorsements) shall provide that the insurer shall give Bank at least twenty (20) days notice
before canceling, amending, or declining to renew its policy. At Bank’s request, Borrower shall
deliver certified copies of policies and evidence of all premium payments. Proceeds payable under
any policy shall, at Bank’s option, be payable to Bank on account of the Obligations.
Notwithstanding the foregoing, (a) so long as no Event of Default has occurred and is continuing,
Borrower shall have the option of applying the proceeds of any casualty policy up to Two Hundred
Fifty Thousand Dollars ($250,000) with respect to any loss, but not exceeding Five Hundred Thousand
Dollars ($500,000) in the aggregate for all losses under all casualty policies in any one year,
toward the replacement or repair of destroyed or damaged property; provided that any such
replaced or repaired property (i) shall be of equal or like value as the replaced or repaired
Collateral and (ii) shall be deemed Collateral in which Bank has been granted a first priority
security interest, and (b) after the occurrence and during the continuance of an Event of Default,
all proceeds payable under such casualty policy shall, at the option of Bank, be payable to Bank on
account of the Obligations. If Borrower fails to obtain insurance as required under this Section
6.7 or to pay any amount or furnish any required proof of payment to third persons and Bank, Bank
may make all or part of such payment or obtain such insurance policies required in this Section
6.7, and take any action under the policies Bank deems prudent.

     6.8 Operating Accounts.

          (a) Maintain all of its and its Subsidiaries’, if any, depository, operating accounts and
securities accounts with Bank and Bank’s Affiliates with all excess funds maintained at or invested
through Bank or an affiliate of Bank; provided, however, Aspen GmbH may maintain
depository, operating accounts and securities accounts in a financial institution located in the
Federal Republic of Germany (the “German Accounts”), in an aggregate amount not to exceed Two
Hundred Fifty Thousand Dollars ($250,000) at any time; provided further, that
Borrower shall have up to sixty (60) days to provide Bank evidence satisfactory to Bank, in its
sole discretion, that, during such sixty (60) day period (the “Account Transition Period”),
Borrower has transitioned all of its and its

-11-

 

Subsidiaries existing depository, operating accounts
and securities accounts maintained at financial institutions other than Bank or Bank’s Affiliates
(other than the German Accounts) to accounts with Bank or Bank’s Affiliates.

          (b) Provide Bank five (5) days prior-written notice before establishing any Collateral Account
at or with any bank or financial institution other than Bank or Bank’s Affiliates. For each
Collateral Account that Borrower at any time maintains, Borrower shall cause the applicable bank or
financial institution (other than Bank) at or with which any Collateral Account is maintained to
execute and deliver a Control Agreement or other appropriate instrument with respect to such
Collateral Account to perfect Bank’s Lien in such Collateral Account in accordance with the terms
hereunder which Control Agreement may not be terminated without the prior written consent of Bank.
The provisions of the previous sentence shall not apply to the German accounts or to deposit
accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments
to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such.

     6.9 Financial Covenants.

          Maintain at all times, to be certified by Borrower as of the last day of each month, unless
otherwise noted, on a consolidated basis with respect to Borrower and its Subsidiaries, unless
otherwise noted:

     6.10 Protection of Intellectual Property Rights. (i) Protect, defend and maintain the
validity and enforceability of its material Intellectual Property; (ii) promptly advise Bank in
writing of material infringements of its Intellectual Property; and (iii) not allow any
Intellectual Property material to Borrower’s business to be abandoned, forfeited or dedicated to
the public without Bank’s written consent, other than where any of the foregoing would not have a
material adverse effect on Borrower’s business, taken as a whole.

     6.11 Litigation Cooperation. From the date hereof and continuing through the termination of
this Agreement, make available to Bank, without expense to Bank, Borrower and its officers,
employees and agents and Borrower’s Books, to the extent that Bank may deem them reasonably
necessary to prosecute or defend any third-party suit or proceeding instituted by or against Bank
with respect to any Collateral or relating to Borrower.

     6.12 Creation/Acquisition of Subsidiaries. Notwithstanding and without limiting the negative
covenant contained in Section 7.3 hereof, in the event Borrower or any Subsidiary creates or
acquires any Subsidiary, Borrower and such Subsidiary shall promptly notify Bank of the creation or
acquisition of such new Subsidiary and, at Bank’s request, in its sole discretion, take all such
action as may be reasonably required by Bank to cause each such Subsidiary to, in Bank’s sole
discretion, become a co-Borrower or Guarantor under the Loan Documents and grant a continuing
pledge and security interest in and to the assets of such Subsidiary (substantially as described on
Exhibit A hereto); and Borrower shall grant and pledge to Bank a perfected security
interest in the stock, units or other evidence of ownership of each Subsidiary.

     6.13 Further Assurances. Execute any further instruments and take further action as Bank
reasonably requests to perfect or continue Bank’s Lien in the Collateral or to effect the purposes
of this Agreement. Borrower shall deliver to Bank, within five (5) days after the same are sent or
received, copies of all correspondence, reports, documents and other filings with any Governmental
Authority regarding compliance with or maintenance of Governmental Approvals or Requirements of Law
or that could reasonably be expected to have a material effect on any of the Governmental Approvals
or otherwise on the operations of Borrower or any of its Subsidiaries.

          Borrower shall not do any of the following without Bank’s prior written consent:

     7.1 Dispositions. Convey, sell, lease, transfer, assign, or otherwise dispose of

of the United States.

     7.2 Changes in Business, Management, Ownership or Business Locations. (a) Engage in or permit

immediately after giving effect to such transaction or related series of such transactions (other

investors so long as Borrower identifies to Bank the venture
capital investors prior to the closing of the transaction and provides to Bank a description
of the material terms of the transaction).

          Borrower shall not, without at least thirty (30) days prior written notice to Bank: (1) add

Thousand Dollars ($50,000) to a bailee at a location other than to a bailee and at a location
already disclosed in the Perfection Certificate, (2) change its jurisdiction of organization, (3)
change its organizational structure or type, (4) change its legal name, or (5) change any
organizational number (if any) assigned by its jurisdiction of organization. If Borrower intends
to deliver any portion of the Collateral valued, individually or in the aggregate, in excess of
Fifty Thousand Dollars ($50,000) to a bailee, and Bank and such bailee are not already parties to a
bailee agreement governing both the Collateral and the location to which Borrower intends to
deliver the Collateral, then Borrower will first receive the written consent of Bank, and such
bailee shall execute and deliver a bailee agreement in form and substance satisfactory to Bank in
its sole discretion.

not permit any Collateral to be subject to any Liens other than the first priority security
interest granted herein or Permitted Liens, or enter into any agreement, document, instrument or
other arrangement (except with or in favor of Bank except as otherwise permitted herein) with any
Person which directly or indirectly prohibits or has the effect of prohibiting Borrower or any
Subsidiary from assigning, mortgaging, pledging, granting a security interest in or upon, or
encumbering any of Borrower’s or any Subsidiary’s Intellectual Property, except as is otherwise
described in the Perfection Certificate, permitted in Section 7.1 hereof and in the definition of

material transaction with any Affiliate of Borrower, except for transactions that are in the
ordinary course of Borrower’s business, upon fair and reasonable terms that are no less favorable

permitted under the terms of the subordination, intercreditor, or other similar agreement to which

company”, under the Investment Company Act of 1940, as amended, or undertake as one of its
important activities extending credit to purchase or carry margin stock (as defined in Regulation U
of the Board of Governors of the Federal Reserve System), or use the proceeds of any Credit
Extension for that purpose; fail to meet the minimum funding requirements of ERISA, permit a
Reportable Event or non-exempt Prohibited Transaction, as defined in ERISA, to occur; fail to
comply with the Federal Fair Labor Standards Act or violate any other law or regulation, if the
violation could reasonably be expected to have a material adverse effect on Borrower’s business, or

Corporation or its successors or any other governmental agency.

     8 EVENTS OF DEFAULT

          Any one of the following shall constitute an event of default (an “Event of Default”) under
this Agreement:

     8.1 Payment Default. Borrower fails to (a) make any payment of principal or interest on any
Credit Extension on its due date, or (b) pay any other Obligations within three (3) Business Days
after such Obligations are due and payable (which three (3) Business Day cure period shall not
apply to payments due on the Revolving Line Maturity Date). During the cure period, the failure to
make or pay any payment specified under clause (a) or (b) hereunder is not an Event of Default (but
no Credit Extension will be made during the cure period);

     8.2 Covenant Default.

          (a) Borrower fails or neglects to perform any obligation in Sections 6.2 (provided,
however, Borrower shall have five (5) Business Days from the scheduled due date to cure any
default under clauses 6.2(a) (ii)-(vi) and clause 6.2(a)(viii)), 6.4, 6.6, 6.7, 6.8, or 6.9, or
violates any covenant in Section 7; or

          (b) Borrower fails or neglects to perform, keep, or observe any other term, provision,
condition, covenant or agreement contained in this Agreement or any Loan Documents, and as to any
default (other than those specified in this Section 8) under such other term, provision, condition,
covenant or agreement that can be cured, has failed to cure the default within ten (10) days after
the occurrence thereof; provided, however, that if the default cannot by its nature
be cured within the ten (10) day period or cannot after diligent attempts by Borrower be cured
within such ten (10) day period, and such default is likely to be cured within a reasonable time,
then Borrower shall have an additional period (which shall not in any case exceed thirty (30) days)
to attempt to cure such default, and within such reasonable time period the failure to cure the
default shall not be deemed an Event of Default (but no Credit Extensions shall be made during such
cure period). Cure periods provided under this section shall not apply, among other things, to
financial covenants or any other covenants set forth in clause (a) above;

     9 BANK’S RIGHTS AND REMEDIES

     9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, without
notice or demand, do any or all of the following:

          (a) declare all Obligations immediately due and payable (but if an Event of Default described
in Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank);

          (b) stop advancing money or extending credit for Borrower’s benefit under this Agreement or
under any other agreement between Borrower and Bank;

          (c) demand that Borrower (i) deposit cash with Bank in an amount equal to 105% of the Dollar
Equivalent of the aggregate face amount of all Letters of Credit remaining undrawn plus all
interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its
good faith business judgment), to secure all of the Obligations relating to such Letters of Credit,
as collateral security for the repayment of any future drawings under such Letters of Credit, and
Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all letter of credit
fees scheduled to be paid or payable over the remaining term of any Letters of Credit;
provided, however, if an Event of Default described in Section 8.5 occurs, the
obligation of Borrower to cash collateralize all Letters of Credit remaining undrawn shall
automatically become effective without any action by Bank;

          (d) terminate any FX Forward Contracts;

          (e) settle or adjust disputes and claims directly with Account Debtors for amounts on terms
and in any order that Bank considers advisable, notify any Person owing Borrower money of Bank’s
security interest in such funds, and verify the amount of such account;

          (f) make any payments and do any acts it considers necessary or reasonable to protect the
Collateral and/or its security interest in the Collateral. Borrower shall assemble the Collateral
if Bank requests and make it available as Bank designates. Bank may enter premises where the
Collateral is located, take and maintain possession of any part of the Collateral, and pay,
purchase, contest, or compromise any Lien which appears to be prior or superior to its security
interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of
its premises, without charge, to exercise any of Bank’s rights or remedies;

          (g) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any
amount held by Bank owing to or for the credit or the account of Borrower;

          (h) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for
sale, and sell the Collateral. Bank is hereby granted a non-exclusive, royalty-free license or
other right to use, without charge, Borrower’s labels, Patents, Copyrights, mask works, rights of
use of any name, trade secrets, trade names, Trademarks, and advertising matter, or any similar
property as it pertains to the Collateral, in completing production of, advertising for sale, and
selling any Collateral and, in connection with Bank’s exercise of its rights under this Section,
Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit;

          (i) place a “hold” on any account maintained with Bank and/or deliver a notice of exclusive
control, any entitlement order, or other directions or instructions pursuant to any Control
Agreement or similar agreements providing control of any Collateral;

          (j) demand and receive possession of Borrower’s Books; and

-16-

 

          (k) exercise all rights and remedies available to Bank under the Loan Documents or at
law or equity, including all remedies provided under the Code (including disposal of the Collateral
pursuant to the terms thereof).

     9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful
attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of
Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b)
sign Borrower’s name on any invoice or bill of lading for any Account or drafts against Account
Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account
Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle, and adjust all
claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge,
encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the
Collateral into the name of Bank or a third party as the Code permits. Borrower hereby appoints
Bank as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect
or continue the perfection of Bank’s security interest in the Collateral regardless of whether an
Event of Default has occurred until all Obligations have been satisfied in full and Bank is under
no further obligation to make Credit Extensions hereunder. Bank’s foregoing appointment as
Borrower’s attorney in fact, and all of Bank’s rights and powers, being coupled with an interest,
are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to
provide Credit Extensions terminates.

     9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.7
or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to
pay under this Agreement or any other Loan Document, Bank may obtain such insurance or make such
payment, and all amounts so paid by Bank are Bank Expenses and immediately due and payable, bearing
interest at the then highest rate applicable to the Obligations, and secured by the Collateral.
Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such insurance
at the time it is obtained or within a reasonable time thereafter. No payments by Bank are deemed
an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

     9.4 Application of Payments and Proceeds. If an Event of Default has occurred and is
continuing, Bank may apply any funds in its possession, whether from Borrower account balances,
payments, proceeds realized as the result of any collection of Accounts or other disposition of the
Collateral, or otherwise, to the Obligations in such order as Bank shall determine in its sole
discretion. Any surplus shall be paid to Borrower or to other Persons legally entitled thereto;
Borrower shall remain liable to Bank for any deficiency. If Bank, in its good faith business
judgment, directly or indirectly enters into a deferred payment or other credit transaction with
any purchaser at any sale of Collateral, Bank shall have the option, exercisable at any time, of
either reducing the Obligations by the principal amount of the purchase price or deferring the
reduction of the Obligations until the actual receipt by Bank of cash therefor.

     9.5 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking
practices regarding the safekeeping of the Collateral in the possession or under the control of
Bank, Bank shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any
loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act
or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss,
damage or destruction of the Collateral.

     9.6 No Waiver; Remedies Cumulative. Bank’s failure, at any time or times, to require strict
performance by Borrower of any provision of this Agreement or any other Loan Document shall not
waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance
herewith or therewith. No waiver hereunder shall be effective unless signed by the party granting
the waiver and then is only effective for the specific instance and purpose for which it is given.
Bank’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Bank
has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one
right or remedy is not an election and shall not preclude Bank from exercising any other remedy
under this Agreement or other remedy available at law or in equity, and Bank’s waiver of any Event
of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a waiver,
election, or acquiescence.

     9.7 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by
Bank on which Borrower is liable.

     11 CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

          Massachusetts law governs the Loan Documents without regard to principles of conflicts of law.
Borrower and Bank each submit to the exclusive jurisdiction of the State and Federal courts in
Massachusetts; provided, however, that nothing in this Agreement shall be deemed to
operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction
to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or
other court order in favor of Bank. Borrower expressly submits and consents in advance to such
jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any
objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non
conveniens and hereby consents to the granting of such legal or equitable relief as is deemed
appropriate by such

-18-

 

court. Borrower hereby waives personal service of the summons, complaints, and
other process issued in such action or suit and agrees that service of such summons, complaints,
and other process may be made by registered or certified mail addressed to Borrower at the address
set forth in Section 10 of this Agreement and that service so made shall be deemed completed upon
the earlier to occur of Borrower’s actual receipt thereof or three (3) days after
deposit in the U.S. mails, proper postage prepaid. NOTWITHSTANDING ANYTHING TO THE CONTRARY
SET FORTH HEREINABOVE, BANK SHALL SPECIFICALLY HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING
AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK DEEMS NECESSARY
OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANK’S RIGHTS AGAINST
BORROWER OR ITS PROPERTY.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A
JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN
DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER
CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH
PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

     12 GENERAL PROVISIONS

     12.1 Termination Prior to Maturity Date. This Agreement may be terminated prior to the
Revolving Line Maturity Date by Borrower, effective three (3) Business Days after written notice of
termination is given to Bank or if Bank’s obligation to fund Credit Extensions terminates pursuant
to the terms of Section 2.1.1(b). Notwithstanding any such termination, Bank’s lien and security
interest in the Collateral shall continue until Borrower fully satisfies its Obligations. Upon
payment in full of the Obligations and at such time as Bank’s obligation to make Credit Extensions
has terminated, Bank shall release its liens and security interests in the Collateral and all
rights therein shall revert to Borrower.

     12.2 Successors and Assigns. This Agreement binds and is for the benefit of the successors
and permitted assigns of each party. Borrower may not assign this Agreement or any rights or
obligations under it without Bank’s prior written consent (which may be granted or withheld in
Bank’s discretion). Bank has the right, without the consent of or notice to Borrower, to sell,
transfer, assign, negotiate, or grant participation in all or any part of, or any interest in,
Bank’s obligations, rights, and benefits under this Agreement and the other Loan Documents;
provided, that, prior to the occurrence and during the continuance of an Event of
Default, any such sale, transfer, assignment, negotiation or grant of a participation to a Person
or entity other than an institutional lender shall require Borrower’s prior written consent, such
consent not to be unreasonably withheld.

     12.3 Indemnification. Borrower agrees to indemnify, defend and hold Bank and its directors,
officers, employees, agents, attorneys, or any other Person affiliated with or representing Bank
(each, an “Indemnified Person”) harmless against: (a) all obligations, demands, claims, and
liabilities (collectively, “Claims”) claimed or asserted by any other party in connection with the
transactions contemplated by the Loan Documents; and (b) all losses or expenses (including Bank
Expenses) in any way suffered, incurred, or paid by such Indemnified Person as a result of,
following from, consequential to, or arising from transactions between Bank and Borrower
contemplated by the Loan Documents (including reasonable attorneys’ fees and expenses), except for
Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful
misconduct.

     12.4 Time of Essence. Time is of the essence for the performance of all Obligations in this
Agreement.

     12.5 Correction of Loan Documents. Bank may correct patent errors and fill in any blanks in
the Loan Documents consistent with the agreement of the parties.

     12.6 Severability of Provisions. Each provision of this Agreement is severable from every
other provision in determining the enforceability of any provision.

     12.7 Amendments in Writing; Waiver; Integration. No purported amendment or modification of
any Loan Document, or waiver, discharge or termination of any obligation under any Loan Document,
shall be enforceable or admissible unless, and only to the extent, expressly set forth in a writing
signed by the party against which enforcement or admission is sought. Without limiting the
generality of the foregoing, no oral promise or

-19-

 

statement, nor any action, inaction, delay, failure
to require performance or course of conduct shall operate as, or evidence, an amendment, supplement
or waiver or have any other effect on any Loan Document. Any waiver granted shall be limited to
the specific circumstance expressly described in it, and shall not apply to any subsequent or other
circumstance, whether similar or dissimilar, or give rise to, or evidence, any obligation or
commitment to grant any further waiver. The Loan Documents represent the entire agreement about
this subject matter and
supersede prior negotiations or agreements. All prior agreements, understandings,
representations, warranties, and negotiations between the parties about the subject matter of the
Loan Documents merge into the Loan Documents.

     12.8 Counterparts. This Agreement may be executed in any number of counterparts and by
different parties on separate counterparts, each of which, when executed and delivered, is an
original, and all taken together, constitute one Agreement.

     12.9 Survival. All covenants, representations and warranties made in this Agreement continue
in full force until this Agreement has terminated pursuant to its terms and all Obligations (other
than inchoate indemnity obligations and any other obligations which, by their terms, are to survive
the termination of this Agreement) have been paid in full and satisfied. The obligation of
Borrower in Section 12.3 to indemnify Bank shall survive until the statute of limitations with
respect to such claim or cause of action shall have run.

     12.10 Confidentiality. In handling any confidential information, Bank shall exercise the same
degree of care that it exercises for its own proprietary information, but disclosure of information
may be made: (a) to Bank’s Subsidiaries or Affiliates (such Subsidiaries and Affiliates, together
with Bank, collectively, “Bank Entities”); (b) to prospective transferees or purchasers of any
interest in the Credit Extensions (provided, however, Bank shall use commercially
reasonable efforts to obtain any prospective transferee’s or purchaser’s agreement to the terms of
this provision); (c) as required by law, regulation, subpoena, or other order; (d) to Bank’s
regulators or as otherwise required in connection with Bank’s examination or audit; (e) as Bank
considers appropriate in exercising remedies under the Loan Documents; and (f) to third-party
service providers of Bank so long as such service providers have executed a confidentiality
agreement with Bank with terms no less restrictive than those contained herein. Confidential
information does not include information that is either: (i) in the public domain or in Bank’s
possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank;
or (ii) disclosed to Bank by a third party if Bank does not know that the third party is prohibited
from disclosing the information.

     Bank Entities may use the confidential information for reporting purposes and the development
and distribution of databases and market analyses so long as such confidential information is
aggregated and anonymized prior to distribution, unless otherwise expressly permitted by Borrower.
The provisions of the immediately preceding sentence shall survive the termination of this
Agreement.

     12.11 Attorneys’ Fees, Costs and Expenses. In any action or proceeding between Borrower and
Bank arising out of or relating to the Loan Documents, Bank shall be entitled to recover its
reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief
to which it may be entitled.

     12.12 Right of Set Off. Borrower hereby grants to Bank, a lien, security interest and right
of set off as security for all Obligations to Bank, whether now existing or hereafter arising upon
and against all deposits, credits, collateral and property, now or hereafter in the possession,
custody, safekeeping or control of Bank or any entity under the control of Bank (including a Bank
subsidiary) or in transit to any of them. At any time after the occurrence and during the
continuance of an Event of Default, without demand or notice, Bank may set off the same or any part
thereof and apply the same to any liability or obligation of Borrower even though unmatured and
regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO
REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES
THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR
OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

     12.13 Electronic Execution of Documents. The words “execution,” “signed,” “signature” and
words of like import in any Loan Document shall be deemed to include electronic signatures or the
keeping of records in electronic form, each of which shall be of the same legal effect, validity
and enforceability as a manually executed signature or the use of a paper-based recordkeeping
systems, as the case may be, to the extent and as provided for in any applicable law, including,
without limitation, any state law based on the Uniform Electronic Transactions Act.

     12.14 Captions. The headings used in this Agreement are for convenience only and shall not
affect the interpretation of this Agreement.

     12.15 Construction of Agreement. The parties mutually acknowledge that they and their
attorneys have participated in the preparation and negotiation of this Agreement. In cases of
uncertainty this Agreement shall be construed without regard to which of the parties caused the
uncertainty to exist.

     12.16 Relationship. The relationship of the parties to this Agreement is determined solely by
the provisions of this Agreement. The parties do not intend to create any agency, partnership,
joint venture, trust, fiduciary or other relationship with duties or incidents different from those
of parties to an arm’s-length contract.

     12.17 Third Parties. Nothing in this Agreement, whether express or implied, is intended to:
(a) confer any benefits, rights or remedies under or by reason of this Agreement on any Persons
other than the express parties to it and their respective permitted successors and assigns; (b)
relieve or discharge the obligation or liability of any Person not an express party to this
Agreement; or (c) give any Person not an express party to this Agreement any right of subrogation
or action against any party to this Agreement.

     12.18 Borrower Agreement; Cross-Collateralization; Cross-Default; Conflicts. Both this
Agreement and the EXIM Borrower Agreement shall continue in full force and effect, and all rights
and remedies under this Agreement and the EXIM Borrower Agreement are cumulative. The term
“Obligations” as used in this Agreement and in the EXIM Borrower Agreement shall include without
limitation the obligation to pay when due all loans made pursuant to the EXIM Borrower Agreement
(the “EXIM Loans”) and all interest thereon and the obligation to pay when due all Advances made
pursuant to the terms of this Agreement and all interest thereon. Without limiting the generality
of the foregoing, the security interest granted herein covering all “Collateral” as defined in this
Agreement and as defined in the EXIM Borrower Agreement shall secure all EXIM Loans and all
Advances and all interest thereon, and all other Obligations. Any Event of Default under this
Agreement shall also constitute a default under the EXIM Borrower Agreement, and any default under
the EXIM Borrower Agreement shall also constitute an Event of Default under this Agreement. In the
event Bank assigns its rights under this Agreement and/or under any note evidencing EXIM Loans
and/or its rights under the Borrower Agreement and/or under any note evidencing Advances, to any
third party, including, without limitation, the EXIM Bank, whether before or after the occurrence
of any Event of Default, Bank shall have the right (but not any obligation), in its sole
discretion, to allocate and apportion Collateral to the EXIM Borrower Agreement and/or note
assigned and to specify the priorities of the respective security interests in such Collateral
between itself and the assignee, all without notice to or consent of the Borrower. Should any term
of the Agreement conflict with any term of the EXIM Borrower Agreement, the more restrictive term
in either agreement shall govern Borrower.

than Fifty Thousand Dollars ($50,000) in the aggregate is in the possession of any third party
bailee (such as at a warehouse).

 

 

In the event that Borrower, after the date hereof, intends to store or otherwise deliver the
Collateral with a value in excess of Fifty Thousand Dollars ($50,000) in the aggregate to such a
bailee, then Borrower shall first receive, the prior written consent of Bank and such bailee must
acknowledge in writing that the bailee is holding such Collateral for the benefit of Bank.
Borrower hereby ratifies, confirms and reaffirms, all and singular, the terms and disclosures
contained in a certain Perfection Certificate, dated as of March 31, 2011, and acknowledges,
confirms and agrees the disclosures and information above Borrower provided to Bank in such
Perfection Certificate remains true and correct in all material respects as of the date hereof.

9. AUTHORIZATION TO FILE. Borrower hereby authorizes Bank to file UCC financing statements
without notice to Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in order
to further perfect or protect Bank’s interest in the Collateral, including a notice that any
disposition of the Collateral, by either the Borrower or any other Person, shall be deemed to
violate the rights of the Bank under the Code.

10. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever necessary
to reflect the changes described above.

11. RATIFICATION OF LOAN DOCUMENTS. Borrower hereby ratifies, confirms, and reaffirms all
terms and conditions of the Loan Agreement, each other Loan Document and all security or other
collateral granted to the Bank, and confirms that the indebtedness secured thereby includes,
without limitation, the Obligations.

12. NO DEFENSES OF BORROWER. Borrower hereby acknowledges and agrees that Borrower has no
offsets, defenses, claims, or counterclaims against Bank with respect to the Obligations, or
otherwise, and that if Borrower now has, or ever did have, any offsets, defenses, claims, or
counterclaims against Bank, whether known or unknown, at law or in equity, all of them are hereby
expressly WAIVED and Borrower hereby RELEASES Bank from any liability thereunder.

13. CONTINUING VALIDITY. Borrower understands and agrees that in modifying the existing
Obligations, Bank is relying upon Borrower’s representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to this Loan
Modification Agreement, the terms of the Existing Loan Documents remain unchanged and in full force
and effect. Bank’s agreement to modifications to the existing Obligations pursuant to this Loan
Modification Agreement in no way shall obligate Bank to make any future modifications to the
Obligations. Nothing in this Loan Modification Agreement shall constitute a satisfaction of the
Obligations. It is the intention of Bank and Borrower to retain as liable parties all makers of
Existing Loan Documents, unless the party is expressly released by Bank in writing. No maker will
be released by virtue of this Loan Modification Agreement.

14. RIGHT OF SET-OFF. In consideration of Bank’s agreement to enter into this Loan
Modification Agreement, Borrower hereby reaffirms and hereby grants to Bank, a lien, security
interest and right of set off as security for all Obligations to Bank, whether now existing or
hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter
in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank
(including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and
during the continuance of an Event of Default, without demand or notice, Bank may set off the same
or any part thereof and apply the same to any liability or obligation of Borrower even though
unmatured and regardless of the adequacy of any other collateral securing the loan. ANY AND ALL
RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL
WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH
DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY
WAIVED.

15. CONFIDENTIALITY. In handling any confidential information, Bank shall exercise the
same degree of care that it exercises for its own proprietary information, but disclosure of
information may be made: (a) to Bank’s Subsidiaries or Affiliates; (b) to prospective transferees
or purchasers of any interest in the Credit Extensions (provided, however, Bank
shall use commercially reasonable efforts to obtain any prospective transferee’s or purchaser’s
agreement to the terms of this provision); (c) as required by law, regulation, subpoena, or other
order; (d) to Bank’s regulators or as otherwise required in connection with Bank’s examination or
audit; (e) as Bank considers appropriate in exercising remedies under the Loan Documents; and (f)
to third-party service providers of

 

 

Bank so long as such service providers have executed a confidentiality agreement with Bank with
terms no less restrictive than those contained herein. Confidential information does not include
information that is either: (i) is in the public domain or in Bank’s possession when disclosed to
Bank, or becomes part of the public domain after disclosure to Bank; or (ii) is disclosed to Bank
by a third party, if Bank does not know that the third party is prohibited from disclosing the
information.

     Bank may use confidential information for the development of databases, reporting purposes,
and market analysis so long as such confidential information is aggregated and anonymized prior to
distribution unless otherwise expressly permitted by Borrower. The provisions of the immediately
preceding sentence shall survive the termination of the Loan Agreement.

16. JURISDICTION/VENUE. Section 11 of the Loan Agreement is hereby incorporated by
reference in its entirety.

17. COUNTERSIGNATURE. This Loan Modification Agreement shall become effective only when it
shall have been executed by Borrower and Bank.

2. DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by the Collateral as
described in the Loan Agreement and EXIM Loan Agreement and the “Intellectual Property Collateral”
as described in a certain Intellectual Property Security Agreement, dated as of March 31, 2011
(together with any other collateral security granted to Bank, the “Security Documents”).
Hereinafter, the Security Documents, together with all other documents evidencing or securing the

3. DESCRIPTION OF CHANGE IN TERMS.

Five Million Dollars ($25,000,000), together with an executed copy of each

executed and/or delivered in connection therewith.

entered into as of June 14, 2011 by and between Borrower and the

consents to the consummation of the Transaction and waives any Event of Default that may otherwise

Purchase Agreement, as evidenced by a certain Amendment No. 2 to Subordinated Note and Warrant

contained in the Fidelity Note Purchase Agreement attached at Exhibit A hereto, in each
case without any material amendment or modification thereto (it being agreed that any

(iii) an incumbency certificate giving the name and bearing a specimen signature of
each individual who shall be so authorized (but only to the extent any signatories have

at a warehouse). In the event that Borrower, after the date hereof, intends to store or otherwise
deliver the Collateral with a value in excess of Fifty Thousand Dollars ($50,000) in the aggregate
to such a bailee, then Borrower shall first receive, the prior written consent of Bank and such

disclosures contained in a certain Perfection Certificate, dated as of March 31, 2011, and

hereof.

Obligations, Bank is relying upon Borrower’s representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to this Loan
Modification Agreement, the terms of the Existing Loan Documents remain unchanged and in full force
and effect. Bank’s agreement to modifications to the existing Obligations pursuant to this Loan
Modification Agreement in no way shall obligate Bank to make any future modifications to the
Obligations. Nothing in this Loan Modification Agreement shall constitute a satisfaction of the
Obligations. It is the intention of Bank and Borrower to retain as liable parties all makers of
Existing Loan Documents, unless the party is expressly released by Bank in writing. No maker will
be released by virtue of this Loan Modification Agreement.

14. RIGHT OF SET-OFF. In consideration of Bank’s agreement to enter into this Loan
Modification Agreement, Borrower hereby reaffirms and hereby grants to Bank, a lien, security

order; (d) to Bank’s regulators or as otherwise required in connection with Bank’s examination or
audit; (e) as Bank

 

 

considers appropriate in exercising remedies under the Loan Documents; and (f) to third-party
service providers of Bank so long as such service providers have executed a confidentiality
agreement with Bank with terms no less restrictive than those contained herein. Confidential
