4.                                       No Waiver. The execution, delivery and performance of this Agreement by Lender and the acceptance by Lender of performance of Borrower hereunder (a) shall not constitute a waiver or release by Lender of any default that may now or hereafter exist under the Loan Documents, (b) shall not constitute a novation of the Loan Documents as it is the intent of the parties to modify the Loan Documents as expressly set out herein, and (c) except as expressly provided in this Agreement, shall be without prejudice to, and is not a waiver or release of, Lender’s rights at any time in the future to exercise any and all rights conferred upon Lender by the Loan Documents or otherwise at law or in equity, including but not limited to the right to accelerate the Indebtedness, if not already accelerated, and to institute collection proceedings against Borrower and/or any right against any other person or entity not a party to this Agreement.  Similarly, the execution, delivery, and performance of this Agreement by Borrower and the acceptance by Borrower of the performance by Lender hereunder shall not, subject to the express provisions of this Agreement, constitute a waiver or release of any of Borrower’s rights under the Loan Documents; provided, however, that Borrower waives any and all claims now or hereafter arising from or related to any delay by Lender in exercising any rights or remedies under the Loan Documents, including, without limitation, any delay in foreclosing on any collateral securing the Indebtedness.

5.                                       Forbearance. So long as this Agreement is not terminated as provided herein, the Lender agrees not to foreclose or attempt to foreclose any collateral securing the Indebtedness, institute suit for

3

collection of the Indebtedness against Borrower or any guarantor, or exercise any other remedies available to it under the Loan Documents or under applicable law for a period of time commencing on the date hereof and extending through and including May 31, 2003 at 5:00 p.m. (the “Forbearance Period”).  Upon termination of the Forbearance Period, or otherwise under the provisions of this Agreement, or if all amounts due and owing under the Credit Agreement, the Indebtedness or other Loan Documents, are not paid in full on or before the expiration of the Forbearance Period, Lender may seek to foreclose upon any collateral and to exercise any other remedies to which Lender may be entitled under the Loan Documents, or applicable law to collect amounts due under the Indebtedness, the Credit Agreement or any other Loan Documents.  Borrower agrees that Borrower will not during the Forbearance Period, initiate any action of any kind against Lender with respect to the Loan Documents, exercise any remedy available under the Loan Documents or otherwise, or make or suffer to exist any type of demand upon Lender with respect to the Obligations.

6.                                       Interest Rate.  During the Forbearance Period, all Indebtedness owed by Borrower to Lender under the Loan Documents shall continue to bear interest at the per annum rate equal to the sum of the Prime Rate plus four percent (4.0%).  The Prime Rate shall be that variable per annum rate announced, from time to time, by the Lender as its Prime Rate.

7.                                       Interest Payments. Borrower shall continue to make the interest payments required by the Forbearance Agreement on or before the 15^th day of each month until the Indebtedness is paid in full.  Such payments shall continue on March 15, 2003, at which time the Borrower shall pay all accrued and unpaid interest due on the Indebtedness.

8.                                       Final Payment.  The Borrower shall pay all outstanding principal and all accrued and unpaid interest on or before the end of the Forbearance Period.

9.                                       Loan Fee.  Borrower acknowledges and affirms that a loan fee in the amount of $50,000.00 is due and owing to the Lender pursuant to the terms of the Second A&R Forbearance Agreement (the “Loan Fee”).  Borrower shall pay Lender the Loan Fee on or before the expiration of the Forbearance Period or upon an event of default as set forth herein, and such payment shall not be applied to the payment of the Indebtedness. Notwithstanding the foregoing, if the Borrower pays the Lender the entire outstanding Indebtedness on or before the expiration of the Forbearance Period and provided no event of default has occurred, the Lender agrees to waive the payment of the Loan Fee.

10.                                 Forbearance Fee.  Borrower acknowledges and affirms that a forbearance fee in the aggregate amount of $100,000.00 is due and owing to the Lender pursuant to the terms of the Third A&R Forbearance Agreement (the “Forbearance Fee”).  The Borrower shall pay the Lender the Forbearance Fee on or before the expiration of the Forbearance Period or upon an event of default as set forth herein, and such payment shall not be applied to the payment of the Indebtedness.  Notwithstanding the foregoing, if the Borrower pays the Lender the entire outstanding Indebtedness on or before the expiration of the Forbearance Period and provided no event of default has occurred, the Lender agrees to waive the payment of the Forbearance Fee.

11                                    Tangible Net Worth.   Paragraph 6.3(H) of the Credit Agreement is amended to read as follows:  “Permit its Tangible Net Worth plus Subordinated Debt to be less than $2,000,000.00.”

13.                                 Borrowing Base Certificate and Compliance Statement.   Prior to the 20^th day of each and every month hereafter, the Borrower shall provide to Lender a Borrowing Base Certificate and Compliance Statement in the form attached hereto as Exhibit “A” signed by an officer of Borrower.

Agreement, the A&R Forbearance Agreement, the Second A&R Forbearance Agreement and the Third A&R Forbearance Agreement, the terms of which shall remain in full effect unless modified herein.  Upon Borrower’s failure to fully and faithfully timely pay Lender any of the payments set forth in this Agreement, the term of this Agreement shall immediately end and terminate without the necessity of notice or demand, and Lender shall be entitled to pursue any and all remedies.  Upon the occurrence of Borrower’s failure to fully and faithfully perform any other obligation with respect to the Loan Documents, the Borrower shall be entitled to such notice and opportunity to cure, if any, as provided in the Loan Documents.

17.                                 Patents.  Borrower hereby agrees that it will take any action reasonably requested by the Lender to insure the attachment, perfection and first priority of, and the ability of the Lender to enforce, the Lender’s security interest in all of the Borrower’s patents received, patent applications or patents that are pending and other intellectual property including, without limitation, any filings that may need to be made with the United States Patent and Trademark Office, any other governmental entity or agency or any other entity or agency of any kind.

18.                                 Representations and Warranties. In order to induce Lender to execute, deliver, and perform this Agreement, Borrower warrants and represents to Lender that:

(a)                                  this Agreement is not being made or entered into with the actual intent to hinder, delay, or defraud any entity or person;

(b)                                 this Agreement is not intended by the parties to be a novation of the Loan Documents and, except as expressly modified herein, all terms, conditions, rights and obligations as set out in the Loan Documents are hereby reaffirmed and shall otherwise remain in full force and effect as originally written and agreed;

(c)                                  no action or proceeding, including, without limitation, a voluntary or involuntary petition for bankruptcy under any chapter of the Federal Bankruptcy Code, has been instituted by or against the Borrower;

(d)                                 to the best of Borrower’s knowledge, and with the sole exception of financial statements projecting profitability for the periods ending September 30, 2002, and December 31, 2002, all balance sheets, and cash flow statements, and all information provided by Borrower to Lender prior to the date hereof, including, without limitation, all financial statements, balance sheets, and cash flow statements, were, at the date of delivery, and are, as of the date hereof, true and correct in all material respects.  Borrower recognizes and acknowledges that Lender is entering into this Agreement based in part on the financial information provided to Lender by Borrower and that the truth and correctness of that financial information is a material inducement to Lender in entering into this Agreement.  During the term of this Agreement, Borrower agrees to advise Lender promptly in writing of any and all new information, facts, or occurrences that would in any way materially supplement, contradict, or affect any financial statements, balance sheets, cash flow statements, or similar items furnished to Lender;

(e)                                  this Agreement and the Loan Documents constitute the entire agreement among Lender and Borrower with respect to this matter;

6

(f)                                    Borrower hereby reaffirms to Lender that Lender has a perfected first priority secured interest in all of Borrower’s patents received, applied for or that are pending and other intellectual property and that Lender has the ability to enforce Lender’s security interest in such patents and other intellectual property; and

19.                                 Bankruptcy.   In entering into this Agreement, Borrower and Lender hereby stipulate, acknowledge and agree that Lender gave up valuable rights and agreed to forbear from exercising legal remedies available to it in exchange for the promises, representations, acknowledgments and warranties of Borrower as contained herein and that Lender would not have entered into this Agreement but for such promises, representations, acknowledgments, agreements, and warranties, all of which have been accepted by Lender in good faith, the breach of which by Borrower in any way, at any time, now or in the future, would admittedly and confessedly constitute cause for dismissal of any such bankruptcy petition pursuant to 11 U.S.C. § 1112(b).  As additional consideration for Lender agreeing to forbear from immediately enforcing its rights and remedies under this Agreement and in the Loan Documents, including but not limited to the institution of foreclosure or collection proceedings, Borrower agrees that in the event a bankruptcy petition under any Chapter of the Bankruptcy Code (11 U.S.C. §101, et seq.) is filed by or against any Borrower at any time after the execution of this Agreement, Lender shall be entitled to the immediate entry of an order from the appropriate bankruptcy court granting Lender complete relief from the automatic stay imposed by §362 of the Bankruptcy Code (11 U.S.C. §362) to exercise its foreclosure and other rights, including but not limited to obtaining a foreclosure judgment and foreclosure sale, upon the filing with the appropriate court of a motion for relief from the automatic stay with a copy of this Agreement attached thereto.  Borrower specifically agrees (i) that upon filing a motion for relief from the automatic stay, Lender shall be entitled to relief from the stay without the necessity of an evidentiary hearing and without the necessity or requirement of the Lender to establish or prove the value of any collateral, the lack of adequate protection of its interest in any collateral, or the lack of equity in any collateral; (ii) that the lifting of the automatic stay hereunder by the appropriate bankruptcy court shall be deemed to be “for cause” pursuant to §362(d)(1) of the Bankruptcy Code (11 U.S.C. §362 (d)(1); and (iii) that Borrower will not directly or indirectly oppose or otherwise defend against Lender’s efforts to gain relief from the automatic stay. This provision is not intended to preclude Borrower from filing for protection under any Chapter of the Bankruptcy Code.  The remedies prescribed in this paragraph are not exclusive and shall not limit Lender’s rights under the Loan Documents, this Agreement or under any law.  All of the above terms and conditions have been freely bargained for and are all supported by reasonable and adequate consideration and the provisions herein are material inducements for Lender entering into this Agreement.

20.                                 Release.  Borrower hereby remises, releases, and forever discharges Lender, its successors and assigns, its officers, directors, employees, agents and attorneys (collectively, “Released Parties”) of and from all actions, causes of action, suits, proceedings, debts, contracts, claims, damages, liability and demands whatsoever, known or unknown, in law or equity, which Borrower ever had or now has, by reason of any matter, cause, or thing whatsoever arising from the actions or inactions of the Released Parties prior to the date hereof including any matter relating to the Agreement, the Loan Documents (collectively, “Released Matters”); and Borrower covenants not to sue any of the Released Parties with respect to the Released Matters.  The release and covenant not to sue set forth in this Section are intended by the parties to be as

7

broad and comprehensive as possible.  However, this release will not cover any intentional torts or acts of gross negligence.

(a)                                  Borrower files a petition for bankruptcy under any chapter of the Federal Bankruptcy Code or takes advantage of any other debtor relief law, or an involuntary petition for bankruptcy under any chapter of the Federal Bankruptcy Code is filed against Borrower, or any other judicial action is taken with respect to Borrower by any creditor;

(b)                                 Lender discovers that any representation or warranty made herein by Borrower was or is untrue, incorrect or misleading in any material respect;

(c)                                  After the date of this Agreement, and except for the financial covenants set forth in Section 6.3 (I) and (J) of the Credit Agreement, Borrower’s breach or default in the performance of any covenant or agreement contained in this Agreement or the Loan Documents;

(d)                                 Lender receives any draft or request for payment in respect of any letter of credit.

(e)                                  Borrower’s failure to comply with any of the terms and conditions of this Agreement.

22.                                 Authorization To File Financing Statements. The Borrower hereby irrevocably authorizes Lender at any time and from time to time to file in any Uniform Commercial Code jurisdiction any financing statements and amendments thereto that: (i) indicate the collateral as that set forth in the Loan Documents, and (ii) contain any other information required by part 5 of Article 9 of the Uniform Commercial Code for the sufficiency or filing office acceptance of any financing statement or amendment.  The Borrower agrees to furnish any of the foregoing information to the Lender promptly upon request. The Borrower ratifies its authorization for the Lender to have filed any like initial financing statements or amendments thereto if filed prior to the date hereof.  The Lender may add any supplemental language to any such financing statement as the Lender may determine to be necessary or helpful in acquiring or preserving rights against third parties.
