PLEDGE AGREEMENT

        This AMENDED PLEDGE AND SECURITY AGREEMENT effective as of the 15th day of January 2002, is by and between Boston Biomedica, Inc. (hereafter the “Pledgor”) and Commerce Bank & Trust Company, a Massachusetts Trust Company organized pursuant to Chapter 172 of the laws of the Commonwealth of Massachusetts, with a principal place of business at 386 Main Street, Worcester, Massachusetts (hereafter the “Lender”).

PRELIMINARY STATEMENTS:

        WHEREAS, Resort Accommodations International, LLC (the "Borrower") is a Massachusetts limited liability company owned by Richard T. Schumacher ("Guarantor").

        WHEREAS, Guarantor is the Chairman and Chief Executive Officer of the Pledgor.

        WHEREAS, on the date hereof, Borrower, Guarantor and Lender are executing and delivering loan documentation to amend certain terms of the loan arrangement currently existing between Borrower, Lender and Guarantor, pursuant to which (i) Lender will, among other things, increase its loan to Borrower by $980,000 from $1,438,000 to $2,418,000 (the “Loan”) pursuant to a Sixth Restated Loan Agreement between Borrower and Lender dated the date hereof (the “Loan Agreement”) and a Sixth Note Modification Agreement between Borrower and Lender dated the date hereof (the “Note”); and (ii) Guarantor will ratify his Unlimited Guaranty dated February 27, 1998 (the “Unlimited Guaranty”) of Borrower’s obligations under the Loan Agreement and the Note, and will secure the obligations of Borrower under the Loan Agreement and the Note and the obligations of Guarantor under the Unlimited Guaranty by further amending that certain Pledge Agreement between Guarantor and Lender dated February 27, 1998, as amended (the “Guarantor’s Pledge Agreement”).

        WHEREAS, the additional proceeds to be received by Borrower in connection with the Loan will be used to satisy various obligations of the Borrower and the Guarantor.

        WHEREAS, Lender has determined that Borrower and Guarantor do not have sufficient collateral to secure the Loan and have thus conditioned the Loan on the receipt from Pledgor of (i) a guaranty of Guarantor’s obligations under the Limited Guaranty, such guaranty to be in the form attached hereto (the “Pledgor’s Guaranty”), and (ii) a pledge of a $1.0 million to be held in an interest bearing account to be held by Lender for the purpose of securing Pledgor’s obligations under the Pledgor’s Guaranty.

        WHEREAS, a special committee of the Board of Directors of Pledgor has reviewed the transactions contemplated between Borrower, Lender and Guarantor and, after deliberation and consideration of alternatives to such transactions, has determined that it is in the best interest of the Pledgor to enter into the Pledgor’s Guaranty and this Pledge Agreement because, among other things, the proceeds from the Loan will (i) enable Guarantor to repay his personal financial debts and obligations which will relieve him of financial pressures that have been and would continue to be a substantial distraction to him and the Pledgor’s business and (ii) avoid the need for the Guarantor to sell a significant portion of his stock of the Pledgor to repay the Loan, thereby eliminating the potential adverse effect on the Pledgor’s stock price and the negative impression that such sales of stock would create to the public stockholders of Pledgor.

        WHEREAS, in connection with this Pledge Agreement, the Pledgor is pledging up to $1,000,000 held in an interest bearing account described in SECTION 1 below (the “Collateral”).

        NOW THEREFORE, in consideration of the mutual premises contained herein and in order to induce the Lender to make the Loan to the Pledgor, the Pledgor agrees as follows:

         SECTION 1.  Pledge.  The Pledgor pledges to the Lender and grants to the Lender a security interest in, the following (the "Collateral"):

Up to $1,000,000 held in Account Number 99001550 at Commerce Bank & Trust Company located at 386 Main Street, Worcester, MA or such other interest bearing account agreed to by the Lender and the Company.

         SECTION 2.   Security for Obligations.  This Agreement secures the payment of up to $1,000,000 of the obligations of the Borrower now or hereafter existing under the Note whether for principal, interest, fees, expenses or otherwise and all other obligations of the Pledgor now or hereafter existing under this Pledge and Security Agreement (all such obligations of the Pledgor being the “Obligations”).

         SECTION 3.  Representation and Warranties.  The Pledgor represents and warrants as follows:

        (a)         The execution, delivery and performance by the Pledgor of this Agreement (A) does not and will not violate (i) any provision of law applicable to the Pledgor, any governmental rule or regulation or (ii) any order of any court or other agency of government binding on the Pledgor or any material indenture, agreement or other instrument to which Pledgor is a party, or by which the Pledgor or any of the Pledgor’s material property is bound, and (B) will not be in conflict with, result in a material breach of or constitute (with due notice and/or lapse of time) a material default under, any such indenture, agreement or other instrument, or result in the creation or imposition of any lien, charge or encumbrance of any nature whatsoever on any property or assets of the Pledgor other than as contemplated by this Agreement.

        (b)         The Pledgor is the legal owner of the Collateral free and clear of any lien, security interest, option or other charge or encumbrance except for the security interest created by this Agreement.

        (c)         The pledge of the Collateral pursuant to this Agreement secures the payment of the Obligations and creates a valid and perfected first priority security interest in the Collateral.

        (d)         No authorization, approval or other action by, and no notice to or filing with, any governmental authority or regulatory body is required either for the pledge by the Pledgor of the Collateral pursuant to this Agreement or for the execution, delivery or performance of this Agreement by the Pledgor.

        (e)         This Agreement constitutes the legal, valid and binding obligation of the Pledgor enforceable against the Pledgor in accordance with its terms, except as the enforceability thereof may be subject to bankruptcy, insolvency, moratorium and other laws affecting the rights and remedies of creditors and secured parties and to the exercise of judicial discretion in accordance with general equitable principles.

Upon the payment in full of the Obligations, the Pledgor shall be entitled to the return, upon request and at its expense, of such of the Collateral as shall not have been sold or otherwise applied pursuant to the terms hereof.

         SECTION 13.  No Waiver; Cumulative Remedies.  No failure on the part of the Lender to exercise, or to delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy by the Lender preclude any other further exercise thereof or the exercise of any other right, power or remedy.

         SECTION 14.  Governing Law; Terms.  This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts (except as required by mandatory provisions of law and except to the extent that validity or perfection of the security interest hereunder, or remedies hereunder, in respect of any particular Collateral are governed by the laws of a jurisdiction other than the Commonwealth of Massachusetts). Unless otherwise defined herein, terms defined in Article 9 of the Uniform Commercial Code in the Commonwealth of Massachusetts are used herein as therein defined.
