AGREEMENT

The parties agree as follows:

1 	ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement will be construed following 
GAAP. Calculations and determinations must be made following GAAP.  The term 
"financial statements" includes the notes and schedules.  The terms "including"
and "includes" always mean "including (or includes) without limitation," in 
this or any Loan Document.  This Agreement shall be construed to impart upon 
Bank a duty to act reasonably at all times.

2 	LOAN AND TERMS OF PAYMENT

2.1 	Advances.

Borrower jointly and severally promises to pay Bank the unpaid principal amount
of all Advances and interest on the unpaid principal amount of the Advances.

2.1.1 	Revolving Advances.

a) Bank will make Advances not exceeding the lesser of (A) the Committed 
Revolving Line or (B) the Borrowing Base. Amounts borrowed under this Section 
may be repaid and reborrowed during the term of this Agreement.

b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by
3:00 p.m. Eastern time on the Business Day the Advance is to be made.  Borrower
must promptly confirm the notification by delivering to Bank the
Payment/Advance Form attached as Exhibit B.  Bank will credit Advances to
Borrower's 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.  Bank may rely on any telephone notice given by a person whom Bank 
believes is a Responsible Officer or designee. Borrower will indemnify Bank for
any loss Bank suffers due to reliance.

c) The Committed Revolving Line terminates on the Revolving Maturity Date, when

or decreases when the Prime Rate changes.  Interest is computed on a 360 day 
year for the actual number of days elapsed. 

b) Payments.  Interest due on the Committed Revolving Line is payable on the 
last day of each month.  Bank may debit any of Borrower's deposit accounts 
including Account Number       0700763970           bjh_   for principal and 
interest payments or any amounts Borrower owes Bank.  Bank will notify Borrower

b) the representations and warranties in Section 5 must be materially true on 
the date of the Payment/Advance Form and on the effective date of each Advance

that the representations and warranties of Section 5 remain true.

4 	CREATION OF SECURITY INTEREST

4.1 	Grant of Security Interest.

Borrower continues to grant Bank a continuing security interest in all 
presently existing and later acquired Collateral to secure all Obligations and 
performance of each of Borrower's duties under the Loan Documents.  Except for
Permitted Liens, any security interest will be a first priority security 
interest in the Collateral.  Bank may place a "hold" on any deposit account 
pledged as Collateral. If this Agreement is terminated, Bank's lien and 
security interest in the Collateral will continue until Borrower fully 
satisfies its Obligations.

5 	REPRESENTATIONS AND WARRANTIES

	Borrower represents and warrants as follows: 

5.1 	Due Organization and Authorization.

Borrower and each Subsidiary is duly existing and in good standing in its state
of formation and qualified and licensed to do business in, and in good standing
in, any state in which the conduct of its business or its ownership of property
requires that it be qualified.

The execution, delivery and performance of the Loan Documents have been duly 
authorized, and do not conflict with Borrower's formation documents, nor 
constitute an event of default under any material agreement by which Borrower 
is bound.  Borrower is not in default under any agreement to which or by which 
it is bound in which the default could cause a Material Adverse Change.

5.2 	Collateral.

Borrower has good title to the Collateral, free of Liens except Permitted 
Liens.  The Accounts are bona fide, existing obligations, and the service or 
property has been performed or delivered to the account debtor or its agent for
immediate shipment to and unconditional acceptance by the account debtor.  
Borrower has no notice of any actual or imminent Insolvency Proceeding of any 
account debtor whose accounts are an Eligible Account in any Borrowing Base 
Certificate.  All Inventory is in all material respects of good and marketable 
quality, free from material defects.  Borrower is the sole owner of the 
Intellectual Property, except for non-exclusive licenses granted to its 
customers in the ordinary course of business.  Each Patent is valid and 
enforceable and no part of the Intellectual Property has been judged invalid or
unenforceable, in whole or in part, and no claim has been made that any part of
the Intellectual Property violates the rights of any third party.  

5.3 	Litigation.

Except as shown in the Schedule, there are no actions or proceedings pending 
or, to Borrower's knowledge, threatened by or against Borrower or any 
Subsidiary  in which an adverse decision could cause a Material Adverse Change.

5.4 	No Material Adverse Change in Financial Statements.

All consolidated financial statements for Borrower, and any Subsidiary, 
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.

5.5 	Solvency.

The fair salable value of Borrower's assets (including goodwill minus 
disposition costs) exceeds the fair value of its liabilities; the 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.

5.6 	Regulatory Compliance.

Borrower is not an "investment company" or a company "controlled" by an 
"investment company" under the Investment Company Act.  Borrower is not engaged
as one of its important activities in extending credit for margin stock (under 
Regulations G, T and U of the Federal Reserve Board of Governors).  Borrower 
has complied with the Federal Fair Labor Standards Act.  Borrower has not 
violated any laws, ordinances or rules, the violation of which could cause a 
Material Adverse Change.  None of Borrower's or any Subsidiary's 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 Subsidiary has timely filed all required tax returns and paid, or made
adequate provision to pay, all taxes, except those being contested in good 
faith with adequate reserves under GAAP.  Borrower and each Subsidiary has 
obtained all consents, approvals and authorizations of, made all declarations 
or filings with, and given all notices to, all government authorities that are 
necessary to continue its business as currently conducted.

5.7 	Subsidiaries.

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

5.8 	Full Disclosure.

No representation, warranty or other statement of Borrower in any certificate 
or written statement 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.

Borrower will do all of the following:

6.1 	Government Compliance.

Borrower will maintain its and all Subsidiaries' legal existence and good 
standing in its jurisdiction of formation and maintain qualification in each

effect on Borrower's business or operations.  Borrower will comply, and have 
each Subsidiary comply, with all laws, ordinances and regulations to which it 
is subject, noncompliance with which could have a material adverse effect on 
Borrower's business or operations or cause a Material Adverse Change.

8 	EVENTS OF DEFAULT

Any one of the following is an Event of Default:

8.1 	Payment Default.

If Borrower fails to pay any of the Obligations when due;

8.2 	Covenant Default.

If Borrower does not perform any obligation in Section 6 or violates any 
covenant in Section 7 or does not perform or observe any other material term, 
condition or covenant in this Agreement, any Loan Documents, or in any 
agreement between Borrower and Bank and as to any default under a term, 
condition or covenant that can be cured, has not cured the default within 10 
days after it occurs, or if the default cannot be cured within 10 days or 
cannot be cured after Borrower's attempts within 10 day period, and the default
may be cured within a reasonable time, then Borrower has an additional period 
(of not more than 30 days) to attempt to cure the default.  During the 
additional time, the failure to cure the default is not an Event of Default 
(but no Advances will be made during the cure period);

8.3 	Material Adverse Change.

(i) If there occurs a material impairment in the perfection or priority of the 
Bank's security interest in the Collateral or in the value of such Collateral 
which is not covered by adequate insurance or (ii) if the Bank determines, 
based upon information available to it and in its reasonable judgment, that 
there is a reasonable likelihood that Borrower will fail to comply with one or 
more of the financial covenants in Section 6 during the next succeeding 
financial reporting period.

8.4 	Attachment.

If any material portion of Borrower's assets is attached, seized, levied on, or
comes into possession of a trustee or receiver and the attachment, seizure or 
levy is not removed in 10 days, or if Borrower is enjoined, restrained, or 
prevented by court order from conducting a material part of its business or if 
a judgment or other claim becomes a Lien on a material portion of Borrower's 
assets, or if a notice of lien, levy, or assessment is filed against any of 
Borrower's assets by any government agency and not paid within 10 days after 
Borrower receives notice.  These are not Events of Default if stayed or if a 
bond is posted pending contest by Borrower (but no Advances will be made during
the cure period);

8.5 	Insolvency.

If Borrower becomes insolvent or if Borrower begins an Insolvency Proceeding or
an Insolvency Proceeding is begun against Borrower and not dismissed or stayed 
within 30 days (but no Advances will be made before any Insolvency Proceeding 
is dismissed);

8.6 	Other Agreements.

If there is a default in any agreement between Borrower and a third party that 
gives the third party the right to accelerate any Indebtedness exceeding 
$100,000 or that could cause a Material Adverse Change;

8.7 	Judgments.

If a money judgment(s) in the aggregate of at least $50,000 is rendered against
Borrower and is unsatisfied and unstayed for 10 days (but no Advances will be 
made before the judgment is stayed or satisfied); or

8.8 	Misrepresentations.

If Borrower or any Person acting for Borrower makes any material 
misrepresentation or material misstatement now or later in any warranty or 
representation in this Agreement or in any writing delivered to Bank or to 
induce Bank to enter this Agreement or any Loan Document.

9 	BANK'S RIGHTS AND REMEDIES

9.1 	Rights and Remedies.

When 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) Settle or adjust disputes and claims directly with account debtors for 
amounts, on terms and in any order that Bank considers advisable;

d) Make any payments and do any acts it considers necessary or reasonable to 
protect its security interest in the Collateral.  Borrower will assemble the 
Collateral if Bank requires 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;

e) 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;

f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, 
advertise for sale, and sell the Collateral.  Bank is 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, service marks, 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; and

	Dispose of the Collateral according to the Code.

9.2 	Power of Attorney.

Effective only when an Event of Default occurs and continues, Borrower 
irrevocably appoints Bank as its lawful attorney to:  (i) endorse Borrower's 
name on any checks or other forms of payment or security; (ii) sign Borrower's 
name on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance 
policies; (iv) settle and adjust disputes and claims about the Accounts 
directly with account debtors, for amounts and on terms Bank determines 
reasonable; and (v) transfer the Collateral into the name of Bank or a third 
party as the Code permits.  Bank may exercise the power of attorney to sign 
Borrower's name on any documents necessary to perfect or continue the 
perfection of any security interest regardless of whether an Event of Default 
has occurred.  Bank's appointment as Borrower's attorney in fact, and all of 
Bank's rights and powers, coupled with an interest, are irrevocable until all 
Obligations have been fully repaid and performed and Bank's obligation to 
provide Advances terminates.

9.3 	Accounts Collection.

When an Event of Default occurs and continues, Bank may notify any Person owing
Borrower money of Bank's security interest in the funds and verify the amount 
of the Account.  Borrower must collect all payments in trust for Bank and, if 
requested by Bank, immediately deliver the payments to Bank in the form 
received from the account debtor, with proper endorsements for deposit.

9.4 	Bank Expenses.

If Borrower fails to pay any amount or furnish any required proof of payment to
third persons Bank may make all or part of the payment or obtain insurance 
policies required in Section 6.5, and take any action under the policies Bank 
deems prudent.  Any amounts paid by Bank are Bank Expenses and immediately due 
and payable, bearing interest at the then applicable rate and secured by the 
Collateral.  No payments by Bank are deemed an agreement to make similar 
payments in the future or Bank's waiver of any Event of Default.

9.5 	Bank's Liability for Collateral.

If Bank complies with reasonable banking practices it is not liable 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 	Remedies Cumulative.

Bank's rights and remedies under this Agreement, the Loan Documents, and all 
other agreements 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 Bank's waiver of any Event of Default is not a 
continuing waiver. Bank's delay is not a waiver, election, or acquiescence. No 
waiver is effective unless signed by Bank and then is only effective for the 
specific instance and purpose for which it was given.

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.

10.2 	Subrogation and Similar Rights.

Notwithstanding any other provision of this Agreement or any other Loan 
Document, each Borrower irrevocably waives all rights that it may have at law 
or in equity (including, without limitation, any law subrogating the Borrower 
to the rights of Bank under the Loan Documents) to seek contribution, 
indemnification, or any other form of reimbursement from any other Borrower, 
or any other Person now or hereafter primarily or secondarily liable for any of
the Obligations, for any payment made by the Borrower with respect to the 
Obligations in connection with the Loan Documents or otherwise and all rights 
that it might have to benefit from, or to participate in, any security for the 
Obligations as a result of any payment made by the Borrower with respect to the
Obligations in connection with the Loan Documents or otherwise.  Any agreement 
providing for indemnification, reimbursement or any other arrangement 
prohibited under this Section 10.2 shall be null and void.  If any payment is 
made to a Borrower in contravention of this Section 10.2, such Borrower shall 
hold such payment in trust for Bank and such payment shall be promptly 
delivered to Bank for application to the Obligations, whether matured or 
unmatured.

10.3 	Waivers of Notice.

Each Borrower waives notice of acceptance hereof; notice of the existence, 
creation or acquisition of any of the Obligations; notice of an Event of 
Default; notice of the amount of the Obligations outstanding at any time; 
notice of intent to accelerate; notice of acceleration; notice of any adverse 
change in the financial condition of any other Borrower or of any other fact 
that might increase the Borrower's risk; presentment for payment; demand; 
protest and notice thereof as to any instrument; default; and all other notices
and demands to which the Borrower would otherwise be entitled.  Each Borrower 
waives any defense arising from any defense of any other Borrower, or by reason
of the cessation from any cause whatsoever of the liability of any other 
Borrower.  Bank's failure at any time to require strict performance by any 
Borrower of any provision of the Loan Documents shall not waive, alter or 
diminish any right of Bank thereafter to demand strict compliance and 
performance therewith.  Nothing contained herein shall prevent Bank from 
foreclosing on the Lien of any deed of trust, mortgage or other security 
instrument, or exercising any rights available thereunder, and the exercise of 
any such rights shall not constitute a legal or equitable discharge of any 
Borrower.  Each Borrower also waives any defense arising from any act or 
omission of Bank that changes the scope of the Borrower's risks hereunder. Each
Borrower hereby waives any right to assert against Bank any defense (legal or 
equitable), setoff, counterclaim, or claims that such Borrower individually may
now or hereafter have against another Borrower or any other Person liable to 
Borrower with respect to the Obligations in any manner or whatsoever.

10.4 	Subrogation Defenses.

Each Borrower waives the benefits, if any, of any statutory or common law rule 
that may permit a borrower to assert any defenses of a surety or guarantor, or 
that may give a borrower the right to require a senior creditor to marshal 
assets, and Borrower agrees that it shall not assert any such defenses or 
rights.

10.5 	Right to Settle, Release.

The liability of Borrowers hereunder shall not be diminished by (i) any 
agreement, understanding or representation that any of the Obligations is or 
was to be guaranteed by another Person or secured by other property, or (ii) 
any release or unenforceability, whether partial or total, or rights, if any, 
which Borrower may now or hereafter have against any other Person, including 
another Borrower, or property with respect to any of the Obligations.

Without notice to any Borrower and without affecting the liability of any 
Borrower hereunder, Bank may (i) compromise, settle, renew, extend the time for
payment, change the manner or terms of payment, discharge the performance of, 
decline to enforce, or release all or any of the Obligations with respect to a 
Borrower, (ii) grant other indulgences to a Borrower in respect of the 
Obligations, (iii) modify in any manner any documents, relating to the 
Obligations with respect to a Borrower, (iv) release, surrender or exchange 
any deposits or other property securing the Obligations, whether pledged by a 
Borrower or any other Person, or (v) compromise, settle renew, or extend the 
time for payment, discharge the performance of, decline to enforce, or release 
all or any obligations of any guarantor, endorser or other Person who is now 
or may hereafter be liable with respect to any of the Obligations.

11 	CHOICE OF LAW , VENUE AND JURY TRIAL WAIVER

THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE 
INTERNAL LAWS OF THE COMMONWEALTH OF MASSACHUSETTS WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAW.  EACH OF BORROWER AND BANK HEREBY SUBMITS TO THE EXCLUSIVE

MASSACHUSETTS, BUT IF FOR ANY REASON THE BANK IS DENIED ACCESS TO SUCH COURTS, 
THEN THE VENUE WILL BE IN THE STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF

DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT 
CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR

CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT.  EACH 
PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL
