(a)Payment of Taxes. Pay and discharge all taxes, assessments and governmental charges or levies imposed upon it or upon its income, profits or business, or upon any properties belonging to it, prior to the date on which penalties attach thereto, and all lawful claims that, if unpaid, might become a lien or charge upon any of the Collateral, provided that Borrower shall not be required to pay any such tax, assessment, charge, levy or claim that is being contested in good faith and by appropriate proceedings if Borrower shall have set aside on its books sufficient reserves with respect thereto.

(b)Preservation of Corporate Existence, etc. Preserve and maintain its corporate existence, rights, franchises and privileges in the jurisdiction of its incorporation, and qualify and remain qualified as a foreign corporation in each jurisdiction in which such qualification is necessary or desirable in view of its business and operations or the ownership or lease of its properties.

Borrower will not declare or pay any dividends, or redeem, retire, or otherwise acquire for value any of its capital stock (or rights, options or warrants to purchase such shares) now or hereafter outstanding, return any capital to its stockholders as such, or make any distribution of assets to its stockholders as such.

4.EVENTS OF DEFAULT. All Obligations shall, at the option of Lender, become immediately due and payable, without presentment, demand, protest or notice, upon the occurrence of an event of default under the Note or upon any other failure of Borrower to pay or perform any obligation to Lender under the Note or this Agreement (an “Event of Default”).

5.REMEDIES. Upon the occurrence of any Event of Default, and at any time thereafter, Lender shall have the rights and remedies of a lender under the Uniform Commercial Code in addition to the rights and remedies provided herein, in the Note, or in any other instrument or paper executed by Borrower and all other rights and remedies available to a Lender at law or in equity. Borrower agrees to pay on demand all costs and expenses (including reasonable attorneys’ fees) incurred or paid by Lender in enforcing the Obligations. Borrower hereby irrevocably appoints Lender the true and lawful attorney for Borrower with full power of substitution, in the name of Lender or in the name of Borrower or otherwise, for the sole benefit of Lender but at the sole expense of Borrower, in the event of a default hereunder: (a) to demand, collect, receive payment of, receipt for, settle, compromise or adjust, and give discharges and releases in respect of the Collateral; (b) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral and to enforce any other rights in respect thereof; (c) to settle, compromise or adjust any suit, action or proceeding described in clause (b) above and, in connection

therewith, to give such discharges or releases as Lender may deem appropriate; (d) to endorse checks, notes, drafts, acceptances, money orders or other instruments or documents evidencing or securing the Collateral. The powers conferred on Lender by this Agreement are solely to protect the interest of Lender and shall not impose any duty upon Lender to exercise any such power, and if Lender shall exercise any such power, he shall be accountable only for amounts that he actually receives as a result thereof and shall not be responsible to Borrower except for willful misconduct.

6.WAIVER. No failure or delay on the part of Lender in exercising any of his rights or remedies hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or remedy preclude any other or future exercise thereof or of any other right or remedy. All rights and remedies under this Agreement are cumulative, and shall not be exclusive of any rights and remedies otherwise available. No waiver by Lender of any default by Borrower shall be effective unless in writing. Borrower waives demand, notice, protest, notice of acceptance of this Agreement, notice of extensions of credit, Collateral received or delivered or other action taken in reliance hereon. Borrower assents to any extension or postponement of the time of payment or any other indulgence, to any substitution, exchange or release of any of the Collateral, to the addition or release of any party or person primarily or secondarily liable, to the acceptance of partial payment thereof and the settlement, compromise, adjustment or discharge of any thereof, all in such manner and at such time or times as Lender may deem advisable, without affecting the Obligations of Borrower hereunder in any manner.

7.PROTECTION OF COLLATERAL. In the absence of willful misconduct, Lender shall have no duty as to the collection or protection of the Collateral or any income thereon, nor as to the preservation of rights against prior parties, nor as to the preservation of any rights pertaining thereto beyond the safe custody of the Collateral in the possession of Lender. Lender may exercise its rights with respect to the Collateral without resort or regard to other collateral or sources of payment or reimbursement for the Obligations of Borrower.

8.FURTHER ASSURANCES. Borrower shall execute and deliver to Lender any and all writings and do any and all things reasonably requested by Lender to carry into effect the provisions and intent of this Agreement. Without limiting the foregoing, Borrower will take all actions necessary to assign its contract rights to Lender or any other purchaser by or through Lender following an Event of Default.

9.ENFORCEMENT COSTS. Borrower shall be obligated to pay to or reimburse Lender for all costs incurred or paid by Lender, including reasonable attorneys’ fees, in connection with the enforcement of its rights under this Agreement.

10.NOTICES. Any demand upon, or notice to, Borrower that Lender may elect to give shall be in writing and delivered personally, via overnight priority U.S. mail or a nationally recognized overnight courier, and deemed delivered the first business day following the date of mailing if not personally delivered, to the address shown at the beginning of this Agreement or as modified by any notice given after the date hereof.

11.BINDING AGREEMENT. The Agreement shall bind Borrower and Borrower’s successors and assigns and shall inure to the benefit of Lender and its successors and assigns.

12.GOVERNING LAW. This Agreement and all rights and obligations hereunder, including matters of construction, validity and performance, shall be governed by the laws of the Commonwealth of Massachusetts without regard to choice or conflict of law principles.
