     or threatened release of any hazardous waste or substance by any person on,

     disposal, release or threatened release occurring prior to Borrower's
     ownership or interest in the properties, whether or not the same was or
     should have been known to Borrower. The provisions of this section of the
     Agreement, including the obligation to indemnify, shall survive the payment

     superior to Lender's Security interests and rights in and to such
     Collateral.

     Binding Effect. This Agreement, the Note and all Security Agreements
     directly or indirectly securing repayment of Borrower's Loan and Note are
     binding upon Borrower as well as upon Borrower's successors,
     representatives and assigns, and are legally enforceable in accordance with
     their respective terms.

     business or commercial related purposes.

CESSATION OF ADVANCES. If Lender has made any commitment to make any Loan to
Borrower, whether under this Agreement or under any other agreement, Lender

(a) Borrower or any Guarantor is in default under the terms of this Agreement or
any of the Related Documents or any other agreement that Borrower or any
Guarantor has with Lender; (b) Borrower becomes insolvent, files a petition in
bankruptcy or similar proceedings, or is adjudged a bankrupt; (c) there occurs a
material adverse change in Borrower's financial condition, in the financial
condition of any Guarantor, or in the value of any Collateral securing any Loan;

interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts

without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts. Borrower authorizes Lender, to the extent permitted by applicable law,
to charge or setoff all sums owing on the indebtedness against any and all such
accounts.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

     Default on Indebtedness. Failure of Borrower to make any payment when due
     on the Loans.

     Other Defaults. Failure of Borrower or any Grantor to comply with or to
     perform when due any other term, obligation, covenant or condition
     contained in this Agreement or in any of the Related Documents, or failure
     of Borrower to comply with or to perform any other term, obligation,
     covenant or condition contained in any other agreement between Lender and
     Borrower.

     False Statements. Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Borrower or any Grantor under this
     Agreement or the Related Documents is false or misleading in any material
     respect, either now or at the time made or furnished.

     Defective Collateralization. This Agreement or any of the Related Documents
     ceases to be in full force and effect (including failure of any Security
     Agreement to create a valid and perfected Security interest) at any time
     and for any reason.
 
     Insolvency. The dissolution or termination of Borrower's existence as a
     going business, the insolvency of Borrower, the appointment of a receiver
     for any part of Borrower's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Borrower.

     Creditor or Forfeiture Proceedings. Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceedings, self-help,
     repossession or any other method, by any creditor of Borrower, any creditor
     of any Grantor against any collateral securing the Indebtedness, or by any
     governmental agency. This includes a garnishment, attachment, or levy on or
     of any of Borrower's deposit accounts with Lender.

     Events Affecting Guarantor. Any of the preceding events occurs with respect
     to any Guarantor of any of the Indebtedness or such Guarantor dies or
     becomes incompetent or any Guarantor revokes any guaranty of the
     indebtedness.
 
     Change in Ownership. Any change in ownership of twenty-five percent (25%)
     or more of the common stock of Borrower.
 
     Insecurity. Lender, in good faith, deems itself insecure.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, all
commitments and obligations of Lender under this Agreement or the Related
Documents or any other agreement immediately will terminate (including any
obligation to make Loan Advances or disbursements), and, at Lender's option, all
Loans immediately will become due and payable, all without notice of any kind to
Borrower, except that in the case of an Event of Default of the type described
in the "Insolvency" subsection above, such acceleration shall be automatic and
not optional.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of 
this Agreement:

     Amendments. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or

lawsuit, Borrower agrees upon Lender's request to submit to the jurisdiction of 
the courts of Strafford County, the State of New Hampshire. This Agreement shall
be governed by and construed in accordance with the laws of the State of New 
Hampshire.

Caption Headings. Caption headings in this Agreement are for convenience 
purposes only and are not to be used to interpret or define the provisions of 
this Agreement.

Consent to Loan Participation. Borrower agrees and consents to Lender's sale or 
transfer, whether now or later, of one or more participation interests in the 
Loans to one or more purchasers, whether related or unrelated to Lender. Lender 
may provide, without any limitation whatsoever, to any one or more purchasers, 
or potential purchasers, any information or knowledge Lender may have about 
Borrower or about any other matter relating to the Loan, and Borrower hereby 
waives any rights to privacy it may have with respect to such matters. Borrower 
additionally waives any and all notices of sale of participation interests, as 
well as all notices of any repurchase of such participation interests. Borrower 
also agrees that the purchasers of any such participation interests will be 
considered as the absolute owners of such interests in the Loans and will have 
all the rights granted under the participation agreement or agreements 
governing the sale of such participation interests. Borrower further waives all
rights of offset or counterclaim that it may have now or later against Lender 
or against any purchaser of such a participation interest and unconditionally 
agrees that either Lender or such purchaser may enforce Borrower's obligation 
under the Loans irrespective of the failure or insolvency of any holder of any 
interest in the Loans. Borrower further agrees that the purchaser of any such 
participation interests may enforce its interests irrespective of any personal 
claims or defenses that Borrower may have against Lender.

Costs and Expenses. Borrower agrees to pay upon demand all of Lender's 
out-of-pocket expenses, including without limitation attorneys' fees. Incurred 
in connection with the preparation, execution, enforcement and collection of 
this Agreement or in connection with the Loans made pursuant to this Agreement. 
Lender may pay someone else to help collect the Loans and to enforce this 
Agreement, and Borrower will pay that amount. This includes, subject to any 
limits under applicable law, Lender's attorneys' fees and Lender's legal 
expenses, whether or not there is a lawsuit, including attorneys' fees for 
bankruptcy proceedings (including efforts to modify or vacate any automatic stay
or injunction), appeals, and any anticipated post-judgment collection services. 
Borrower also will pay any court costs, in addition to all other sums provided 
by law.

Notices. All notices required to be given under this Agreement shall be given in
writing and shall be effective when actually delivered or when deposited with a 
nationally recognized overnight courier or deposited in the United States mail, 
first class, postage prepaid, addressed to the party to whom the notice is to be
given at the address shown above. Any party may change its address for notices 
under this Agreement by giving formal written notice to the other parties, 
specifying that the purpose or the notice is to change the party's address. To 
the extent permitted by applicable law, if there is more than one Borrower, 
notice to any Borrower will constitute notice to all Borrowers. For notice 
purposes, Borrower agrees to keep Lender informed at all times of Borrower's 
current address(es).

Severability. If a court of competent jurisdiction finds any provision of this 
Agreement to be invalid or unenforceable as to any person or circumstance, such 
finding shall not render that provision invalid or unenforceable as to any other
persons or circumstances. If feasible, any such offending provision shall be 
deemed to be modified to be within the limits of enforceability or validity; 
however, if the offending provision cannot be so modified, it shall be stricken
and all other provisions of this Agreement in all other respects shall remain 
valid and enforceable.

Subsidiaries and Affiliates of Borrower. To the extent the context of any 
provisions of this Agreement makes it appropriate, including without limitation 
any representation, warranty or covenant, the word "Borrower" as used herein 
shall include all subsidiaries and affiliates of Borrower. Notwithstanding the 
foregoing however, under no circumstances shall this Agreement be construed to 
require Lender to make any Loan or other financial accommodation to any 
subsidiary or affiliate of Borrower.

Successors and Assigns. All covenants and agreements contained by or on behalf 
of Borrower shall bind its successors and assigns and shall inure to the benefit
of Lender, its successors and assigns. Borrower shall not, however, have the 
right to assign its rights under this Agreement or any interest therein, without
the prior written consent of Lender.

Survival. All warranties, representations, and covenants made by Borrower in 
this Agreement or in any certificate or other instrument delivered by Borrower 
to Lender under this Agreement shall be considered to have been relied upon by 
Lender and will survive the making of the Loan and delivery to Lender of the 
Related Documents, regardless of any investigation made by Lender or on Lender's
behalf.

Time is of the Essence. Time is of the essence in the performance of this 
Agreement.

Waiver. Lender shall not be deemed to have waived any rights under this 
Agreement unless such waiver is given in writing and signed by Lender. No delay 
or omission on the part of Lender in exercising any right shall operate as a 
waiver of such right or any other right. A waiver by Lender of a provision of 
this Agreement shall not prejudice or constitute a waiver of Lender's right 
otherwise to demand strict compliance with that provision or any other provision
of this Agreement. No prior waiver by Lender, nor any course of dealing between 
Lender and Borrower, or between Lender and any Grantor, shall constitute a 
waiver of any of Lender's rights or of any obligations of Borrower or of any 
Grantor as to any future transactions. Whenever the consent of Lender is 
required under this Agreement, the granting of such consent by Lender in any 
instance shall not constitute continuing consent in subsequent instances where 
such consent is required, and in all cases such consent may be granted or 
withheld in the sole discretion of Lender.
