NOW, THEREFORE, in consideration of the premises and the mutual covenants and promises herein contained, the parties hereto agree as follows:

1. Definitions

As used above and in this Agreement, the following terms shall have the meanings ascribed to them below:

1.1 “Availability” shall mean, at any time, the amount of the Revolving Advances and Letters of Credit available to Borrower at such time based on the applicable advance percentage multiplied by the value of eligible Collateral as set forth in the Loan Agreement, as determined by Lender in its sole discretion, and subject to the applicable sublimits and reserves established by Lender in its sole discretion.

1.2 “Borrower” shall mean OPTA SYSTEMS, LLC, a Delaware limited liability company, and its successors and assigns, including, without limitation, a receiver, administrator, custodian, liquidator, trustee or debtor-in-possession on behalf of such person or on behalf of any such successor or assign.

1.3 “Collateral” shall have the meaning set forth in the Loan Agreement.

1.4 “Collections” shall mean all cash or other immediately available funds received by Lender for application to the Obligations, whether as proceeds of Collateral or otherwise.

1.6 “Financing Agreements” shall mean, collectively, the Loan Agreement and all agreements, documents and instruments at any time executed and/or delivered by Borrower, any obligor or any other person with, to or in favor of Lender in connection therewith or related thereto, as all of the foregoing now exist or may hereafter be amended, modified, supplemented, extended, renewed, restated or replaced.

1.12 “Revolving Advances” shall have the meaning set forth in the Loan Agreement.

1.13 “Settlement Period” shall mean each week or such other period of time as the parties may agree between settlements in respect of the Participation as provided in Section 3.3 hereof.

1.14 All capitalized terms as used herein shall have the meanings given to such terms in the Loan Agreement, unless otherwise defined herein. All references to Participant and Lender pursuant to the definitions set forth above, or to any other person herein, shall include their respective successors and assigns. All references to any term in the plural shall include the singular and all references to any term in the singular shall include the plural. For purposes of this Agreement, all references to the pro rata share of Participant herein shall be determined based on the Participation Percentage.

2. Purchase and Sale of Participation

2.1 Lender hereby agrees to sell to Participant and Participant hereby unconditionally and irrevocably agrees to purchase from Lender an undivided fractional interest in all present and future Loans made from time to time by Lender to Borrower equal to the Participation Percentage, but in no event to exceed the Participant Commitment at any time outstanding. Participant hereby assumes its pro rata share of all commitments and obligations of Lender under the Financing Agreements or otherwise in connection with the Loans and Letters of Credit. Such interests of Participant in the Loans and Letters of Credit provided for in this Section 2.1 are referred to herein as the “Participation.” Participant shall participate in the Collections and the Collateral, but only to the extent necessary to earn interest (or other compensation, if any) as provided below and to be repaid principal to the extent of the Participation.

2.2 The relationship between Lender and Participant under this Agreement is and shall be that of a seller and purchaser of an undivided fractional interest, not a debtor-creditor relationship. Lender has not guaranteed repayment to Participant of, nor agreed to repurchase from Participant, any portion of the Participation at any time. Lender does not assume and shall not have any liability to Participant for the repayment of monies paid hereunder by Participant to Lender on account of the purchase of the Participation or interest thereon (or other compensation, if any). Nothing contained herein shall confer upon Lender or Participant any interest in, or subject either of them to any liability for, or in respect of, the business, assets, profits, losses or liabilities of the other, except only as to the Participation.

2.3 Participant shall pay Lender the amount of the Participant Commitment in immediately available U.S. funds no later than July 26, 2005. An amount equal to eighty percent (80%) of the outstanding Revolving Advances shall constitute the purchase price for the Participation and belong to Lender and the balance (if any) of the Participant Commitment shall be deposited by Lender into a segregated non-interest bearing account belonging to Participant (the “Loan Funding Account”) for use by Lender in funding Participant’s share of any future Revolving Advances to be made under the Loan Agreement during the Forbearance Period (as defined in the 7/22/05 Forbearance Agreement). Furthermore, Participant shall deposit with Lender (no later than July 26, 2005) immediately available U.S. funds in the amount of $800,000.00 (the “Cash Collateral”) which will be held in a segregated non-interest bearing account and serve as additional collateral for repayment of the Obligations owing to Lender under the Loan Agreement and the Guaranty. Participant hereby grants to Lender a first-priority lien and security interest in the Cash Collateral. Contemporaneously with and only upon Participant’s execution of this Agreement payment by Participant to Lender of the Participant Commitment and the Cash Collateral, Lender will release its Lien on the Collateral that constitutes Intellectual Property Rights. Participant shall pay Lender a fee (the “Servicing Fee”) for administering the Loans in an amount equal to one-half of one percent (.5%) of the average daily amount of Revolving Advances outstanding under the Loan Agreement. The Servicing Fee shall be payable monthly (for all or any portion of a month) upon demand by Lender. Furthermore, Participant shall, upon request by Lender, reimburse Lender for all of Lender’s costs and expenses (including attorneys’ fees) incurred in relation to the negotiation and documentation of this Agreement and the transactions contemplated by this Agreement.

2.4 Participant shall be deemed to have purchased its Participation to each Loan on the date such Loan is made, but Participant’s right to receive its share of any interest paid in respect thereof shall accrue from the date Lender receives immediately available funds from Participant for its Participation Percentage in such Loan.

2.5 Nothing contained in this Agreement and no action taken by Lender with respect to the Loan Agreement or this Agreement shall impair, limit, release, discharge, alter, amend or modify the duties, obligations and liabilities of Participant under the Guaranty.

3. Administration

3.1 The Obligations, the Collateral, and the Collections shall be held by Lender in Lender’s name, but, to the extent of the Participation, as agent for Participant solely as to Participant’s share of Collections received by Lender and subject to Participant’s rights with respect thereto as set forth herein. Except with respect to Participant’s pro rata share of Collections actually received and retained by Lender, Lender shall not be an agent or trustee for Participant in administering or servicing the Financing Agreements, nor with respect to any rights, remedies or benefits thereunder, including making the Loans, providing Letters of Credit, the perfection of security interests and other liens in the Collateral, attempts to effect Collections, execution of agreements in connection therewith, or the exercise of any other rights and remedies of a lender or secured party with respect thereto. Lender shall not be deemed a fiduciary for Participant.

3.2 Lender shall have the right to carry out the provisions of the Financing Agreements with Borrower, and to exercise all rights and privileges accruing to it by reason of the provisions thereof, and to enforce its rights thereunder for the joint benefit of Lender and Participant, according to Lender’s discretion and the exercise of its business judgment, in accordance with its normal operating procedures. Lender will use normal prudence and judgment in the servicing of the arrangements of Lender with Borrower and to the carrying out of the terms of the Financing Agreements. Except as otherwise specifically provided herein, Lender shall have the right to agree to amendments, modifications, waivers or releases of Borrower, and with respect to any provision of the Financing Agreements or any rights of Lender in and to any Collateral or to consent to any action or failure to act by Borrower. Lender shall not have any liability to Participant with respect to any action taken or omitted by Lender, its employees or agents, in connection with the Financing Agreements or for any error in judgment, except for its own gross negligence or willful misconduct. Lender does not assume, and shall not have, any responsibility or liability, express or implied, for the enforceability or collectability of the Financing Agreements, the Collateral or the condition of Borrower, financial or otherwise, or the Collateral, or for the accuracy of any credit or other information furnished by or on behalf of Borrower, unless Lender has acted with gross negligence or willful misconduct.

3.3 Lender shall transmit to Participant after the end of each Settlement Period a statement of the account of Borrower with Lender summarizing the Loans, the status of the

Collateral and the Collections received by Lender during such preceding Settlement Period. The statement of account for such Settlement Period shall state the net loan balance and Collateral balance with Borrower, and the net amount either due from Lender to Participant or the net amount due from Participant to Lender, as the case may be, and the balance in the Loan Funding Account both before and after the credit or debit, as the case may be, to such Account on account of Revolving Advances made or repaid during such Settlement Period. Any sums due from Lender to Participant on account of the net amount of the principal amount of Revolving Advances repaid in excess of the principal amount of Revolving Advances made during such Settlement Period shall be paid by crediting such Account. Any sums due from Participant to Lender on account of the net amount of the principal amount of Revolving Advances made in excess of Revolving Advances repaid during such Settlement Period shall be paid by debiting such Account. Any sums due from Participant to Lender will be paid within five (5) business days of demand made by Lender. In the event that Participant fails to purchase and pay for the Participation as required pursuant to this Agreement or otherwise defaults in its obligations to Lender under this Agreement, Participant shall pay all costs and expenses of every kind incurred by Lender for collection or enforcement of same, including attorneys’ fees and legal expenses. So long as Participant shall be in default of any of its obligations hereunder or under the Guaranty and any amount of obligations shall be due and owing, Participant shall not be entitled to any payments pursuant to the settlement provided for in this Section 3.3 or other payments pursuant to Section 4 below, or to any right to approve any amendments or waivers as provided herein. Any amounts so withheld from Participant will be applied to the amounts owing by Participant. Lender’s books and records showing the account between Lender and Borrower and statements of account rendered to Participant shall be considered accurate unless objected to by Participant in writing within fifteen (15) days from their date.

3.4 Lender will deliver to Participant on or about the tenth (10th) day of each calendar month, a copy of the monthly statement of account with Borrower for the preceding calendar month.

3.5 In the event of the liquidation of the Collateral, all costs and expenses of collection of the Loans and/or disposition or realization upon the Collateral, including, without limitation, attorneys’ fees and expenses, shall constitute a part of the Loans by Lender to Borrower under this Agreement and shall be borne by Lender and Participant pro rata in accordance with their respective interests in the Loans hereunder. In the event of liquidation, all Collections thereafter received shall be applied as follows: (a) first, to the payment in full of the expenses of the collection and enforcement of the Obligations and for the protection, preservation, maintenance or sale, disposition or other realization upon any of the Collateral, including all reasonable expenses, liabilities and advances incurred or made by Lender in connection therewith (including attorneys’ fees and legal expenses); (b) second, to the payment of interest, fees and indemnities payable by Borrower under the Financing Agreements; and (c) third, to the payment in full of all other Obligations (and in the case of Letters of Credit, to be held as cash collateral) in such amounts, order and manner as Lender may determine.

3.6 Lender may (with or without Participant’s consent) modify, alter or amend any provision of the Financing Agreements or waive or release any rights against Borrower. Furthermore, Lender may release any Collateral without the consent of Participant: (i) upon the termination of the Loan Agreement and payment and satisfaction in full by Borrower of all

Loans and the delivery of cash collateral in respect of Letters of Credit, (ii) constituting property being sold or disposed of by Borrower in connection with any sale or other disposition permitted under the Loan Agreement, (iii) constituting property in which Borrower owned no interest at the time the security interest was granted or at any time thereafter, (iv) constituting property leased to Borrower under a lease which has expired or been terminated in a transaction permitted under the Loan Agreement or (v) upon the sale or other disposition of any Collateral which in the good faith determination of Lender is not material or otherwise in connection with the liquidation by Lender of the Collateral.

3.7 Except as otherwise provided in Section 3.8 below, Lender shall not, intentionally and with actual knowledge, make Revolving Advances to Borrower that would cause the aggregate principal amount of the outstanding Revolving Advances to exceed the Availability as of the date of such Revolving Advances, without Participant’s consent, except that:

(a) in the event Lender obtains actual knowledge that the outstanding Revolving Advances exceeds the Availability, Lender shall use all reasonable efforts to make arrangements with Borrower, acceptable to Lender, intended to eliminate such excess amounts within a reasonable time;

(b) Lender may, from time to time, make Revolving Advances with actual knowledge that such Revolving Advances will cause the total outstanding Revolving Advances to exceed the Availability at such time by an amount up to ten percent (10%) of such Availability, provided, that, as of the date of the first such Revolving Advances, Lender has made arrangements with the Borrower intended to eliminate such excess amounts within a reasonable time.

3.8 Lender may, from time to time, at its option, intentionally and with actual knowledge, make Revolving Advances in excess of the Availability at such time by more than ten percent (10%) of such Availability or make Revolving Advances in excess of the Maximum Line, but such Revolving Advances shall be for the sole account of Lender, except as Lender and Participant may otherwise agree. Any such Revolving Advances made by Lender intentionally and with actual knowledge that cause the total outstanding Revolving Advances to exceed the Availability at such time by more than ten percent (10%) or the Maximum Line, as the case may be, shall be prior in right of payment to all other Revolving Advances, such that any Collections shall be applied first to the Revolving Advances which exceed the Availability and thereafter to the balance of the Revolving Advances.

3.9 In the event that at any time, whether before or after the termination of this Agreement, there shall be any claim, action, suit or proceeding of any kind, arising directly or indirectly out of the financing arrangements between Lender and Borrower under or in relation to the Financing Agreements or otherwise, including, without limitation, any action brought against Lender by Borrower, or by any other person claiming by, through or under Borrower, to recover damages for any act taken or omitted by Lender under the Financing Agreements or in pursuing any rights or remedies of Lender against Borrower, any account debtors of Borrower, or for recovery or return of payments or Collateral or proceeds thereof received by Lender, then Participant shall be required to pay to Lender its pro rata share of such amount as Lender shall be

required to pay by reason of a judgment, final decree, or other order, entered in connection with any such claim, action, suit or proceeding or by reason of any compromise or settlement agreed to by Lender, including, without limitation, all interest and costs assessed against or incurred by Lender in defending or compromising such action. Lender shall notify Participant of the commencement against Lender of any such claim, action, suit or proceeding which Lender, in good faith, believes may result in a material judgment against Lender; provided, that, the failure to give such notice shall not entitle Participant to any greater rights or reduce Participant’s obligations with respect to such claim, action, suit or proceeding or otherwise than if Lender did not herein specifically obligate itself to give such notice to Participant. Participant shall not, under the terms of this Section 3.9 or otherwise have any obligation or liability to Lender in the case of Lender’s own gross negligence or willful misconduct.

3.10 If Borrower becomes subject to a case under the U.S. Bankruptcy Code and if Lender desires to permit the use of cash collateral or to provide financing to Borrower under either Section 363 or Section 364 of the U.S. Bankruptcy Code, Lender may, in its discretion, continue to make Loans and provide Letters of Credit after the commencement and during the continuation of such case and such Loans and Letters of Credit shall be subject to the Participation and the terms hereof. Notwithstanding anything to the contrary contained in Section 3.6 hereof, the consent of Participant to any amendments or waivers with respect to the Financing Agreements in connection therewith shall not be required to the extent such amendments make the terms of the Financing Agreements more favorable or such amendments or waivers are required as a result of the commencement of the case of Borrower under the U.S. Bankruptcy Code.

4. Compensation

4.1 Lender agrees to accrue and account to Participant on or about the tenth (10th) day of each calendar month, the interest due Participant in respect of the Participation during the previous calendar month. Participant shall accrue interest in respect of the closing daily balances in the Borrower’s loan account for each day during the immediately preceding calendar month as such interest is earned and actually received by Lender from Borrower pursuant to the terms of the Financing Agreements, to the extent of the actual amounts funded in respect thereof by Participant pursuant to the Participation, at a rate equal to the interest rate payable to Lender under the terms of the Financing Agreements and in the event Lender exercises its option to receive the higher rate of interest provided for in the Loan Agreement after an Event of Default then at such higher rate. Any amount accrued and payable in respect of interest to Participant hereunder shall bear interest at the Base Rate and shall be calculated and payable monthly in arrears and shall be calculated on the basis of a three hundred sixty (360) day year based on actual days elapsed. The interest rate shall increase or decrease by an amount equal to each increase or decrease in the Base Rate, effective on the effective date of any such change. All accrued interest and any other sums owing to Participant will be paid within five (5) business days following the end of the Forbearance Period under the 7/22/05 Forbearance Agreement.

4.2 The interest earned and due Participant in respect of the Loans as set forth above shall be the sole compensation to Participant. Without limiting the foregoing, in no event shall Participant be entitled to any compensation in the form of any unused line fee, any letter of credit fee, any forbearance fee, any termination fee, or any other fee paid by Borrower to Lender pursuant to the Loan Agreement.

5. Credit Decision: Independent Investigation

5.1 Lender makes no representation or warranty (express or implied) and shall have no responsibility, as to the validity, value, enforceability or collectability of the Participation or the Obligations, the Financing Agreements, or as to the title to, validity, priority, value, perfection or sufficiency of the Collateral, or any other guarantees or collateral of any kind, or as to the financial condition of Borrower or any account debtors. Participant has conducted its own independent investigation as to the business and financial condition of Borrower, and is thoroughly familiar with, and has complete and current information concerning the financial condition and creditworthiness of Borrower and the Collateral. Participant has, independently and without reliance upon Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Participant has not in any way relied on Lender or any of its employees in purchasing the Participation. Participant agrees that it will, independently and without reliance upon Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis and decisions with respect to the Participation sold and transferred to it pursuant to this Agreement.

5.2 Participant acknowledges that it has received and reviewed or had the opportunity to receive and review copies of the Financing Agreements and such financial data or other information concerning Borrower or the Collateral existing on the date hereof as Participant has requested from Borrower or Lender.

5.3 Participant acknowledges that Borrower is in material breach and default of its duties and obligations under the Loan Agreement.

D. Notwithstanding Borrower’s breaches and defaults, Participant has acquired from Lender, upon the terms and conditions set forth in a Participation Agreement dated July 26, 2005 (the “Participation Agreement”), an undivided fractional interest in all present and future loans and other financial accommodations provided by Lender to Borrower under the Loan Agreement and, to the extent necessary to repay the Participation, an undivided fractional interest in the Collateral; and

(a) The Participant Commitment is hereby temporarily increased from $3,200,000 to $5,200,000 by restating Section 1.10 of the Participation Agreement to read as follows:

1.10 “Participant Commitment” shall mean (i) $5,200,000 for the period from and including August 25, 2005 to and including September 30, 2005, at which time the Maximum Line under the Loan Agreement is reduced to an amount not greater than $4,000,000, and (ii) $3,200,000 at all other times.
