         DM Management Company, of 25 Recreation Park Drive, Hingham,

substitutions thereto or therefor and any or all proceeds thereof, viz: Specific
business assets located at: its Tilton, New Hampshire facility (the premises),
as set forth in SCHEDULE A attached and made a part hereof; to secure Debtors

         DEBTOR hereby warrants and covenants:

1.   That except for the security interest granted hereby DEBTOR is, or to the
     extent that this agreement states that the Collateral is to be acquired
     after the date hereof, will be, the owner of the Collateral free from any
     adverse lien, security interest or other encumbrance; and that DEBTOR will
     defend the Collateral against all claims and demands of all persons, at any
     time claiming the same or any interest;

2.   That the Collateral is not used or bought primarily for personal, family or

     PARTY of any change in the location of the Collateral within said State;
     and that DEBTOR will not remove the Collateral from said State without the
     written consent of SECURED PARTY;

4.   That no Financing Statement covering any Collateral or any proceeds hereof
     is on file in any public office, and at the request of SECURED PARTY,
     DEBTOR will join with SECURED PARTY in executing one or more Financing
     Statements pursuant to the Uniform Commercial Code in form satisfactory to
     SECURED PARTY and will pay the cost of filing the same in all public
     offices wherever filing is deemed by SECURED PARTY to be necessary or
     desirable;

5.   That DEBTOR will not sell or offer to sell or otherwise transfer the
     Collateral or any interest therein without the written consent of SECURED
     PARTY, except within the normal course of its business;

6.   That DEBTOR will have and maintain insurance at all times with respect to
     all Collateral against risks of fire (including so-called extended
     coverage), theft, and other risks as SECURED PARTY may require, containing
     such terms, in such form, for such periods and written by such companies as
     may be satisfactory to SECURED PARTY, such insurance to be payable to
     SECURED PARTY and DEBTOR as their interests may appear; that all policies
     of insurance shall provide for ten days' written minimum


                                       2

    
     cancellation notice to SECURED PARTY and at request of SECURED PARTY
     copies of such policies shall be delivered to and held by it.

7.   That DEBTOR will keep the Collateral free from any adverse lien, security
     interest or encumbrance except those set forth on Exhibit A hereto
     ("permitted Encumbrances") and in good order and repair and will not waste
     or destroy the Collateral or any part thereof; that DEBTOR will not use the
     Collateral in violation of any statute or ordinance; that SECURED PARTY may
     examine and inspect the Collateral at any time, wherever located; and that
     the security interest set forth in this Security Agreement does not violate
     the provisions of any prior security agreements;

8.   That DEBTOR will pay promptly when due all taxes and assessments upon the
     Collateral or for its use or operation or upon this agreement or upon any
     note or notes evidencing the Obligations;

9.   At all reasonable times, and with reasonable notice, the DEBTOR will permit
     the SECURED PARTY, its accountants, auditors, or attorneys to make such
     examination and inspection of the DEBTOR's books, accounts, orders,
     correspondence and other records, relating to the collateral including the
     making of copies thereof or extracts therefrom, as the SECURED PARTY may
     request;

10.  At the request of the SECURED PARTY, the DEBTOR will execute and deliver to
     the SECURED PARTY such further documents and instruments of assurance and
     will do such further acts as the SECURED PARTY may deem necessary or
     advisable to assure to the SECURED PARTY all rights given or intended to be
     given to the SECURED PARTY hereby or hereunder;

         At its option, and upon five (5) days prior written notice to Debtor,
except for Permitted Encumbrances, SECURED PARTY may discharge taxes, liens or
security interests or other encumbrances at any time levied or placed on the
Collateral, and may pay for insurance on the Collateral and may pay for the
maintenance and preservation of the Collateral. DEBTOR agrees to reimburse
SECURED PARTY on demand for any payment made or any expense incurred by SECURED
PARTY pursuant to the foregoing authorization.

         Until an event of default under the Loan Agreement shall occur and be
continuing, DEBTOR may have possession of the Collateral and use it in any
lawful manner not inconsistent with this agreement and not inconsistent with any
policy of insurance thereon.

         DEBTOR shall be in default under this agreement upon the occurrence of
any event of default specified in the Loan Agreement.

         Upon the occurrence and continuance of such an event of default SECURED
PARTY may declare all obligations secured hereby immediately due and payable and
shall have the remedies of a secured party under the Uniform Commercial Code.
SECURED PARTY may require DEBTOR to assemble the Collateral and make it
available to SECURED PARTY at a place to be designated by SECURED PARTY which is
reasonably convenient to both parties. Whenever notification with respect to the
sale or other disposition of the Collateral is required by law, such
notification of the time and place of public sale, or of the date after which a
private sale or other intended disposition is to be made, shall be deemed
reasonable if mailed, postage prepaid, addressed to DEBTOR at the mailing
address hereinabove given at least ten (10) days before the time of such public
sale or the date after which any such private sale or other intended disposition
is to be made, as 



                                       3


the case may be. Expenses of retaking, holding, preparing for sale, selling or
the like shall include SECURED PARTY's reasonable attorneys' fees and legal
expenses.

         No waiver by SECURED PARTY of any default shall operate as a waiver of
any other default or of the same default on a future occasion.

         All rights of SECURED PARTY hereunder shall inure to the benefit of its
successors and assigns; and all obligations of the DEBTOR shall bind its
successors or assigns.

         Schedule A may be amended hereafter by the submission from DEBTOR to
SECURED PARTY of a list of additional equipment purchased with proceeds of the
funds borrowed under the Loan Agreement.

         This agreement shall become effective when it is signed by DEBTOR. This
agreement and all rights and obligations hereunder, including matters of
construction, validity and performance, shall be governed by the law of New
Hampshire.


Executed on the day and year first above written.
