Definitions: "Current assets," and "current liabilities" shall have the meanings ascribed to them in accordance with generally accepted accounting principles. "Tangible net worth" means the excess of total assets over total liabilities, determined in accordance with generally accepted accounting 2 3 principles, excluding however all assets which would be classified as intangible assets under generally accepted accounting principles, including without limitation goodwill, licenses, patents, trademarks, trade names, copyrights, capitalized software and organizational costs, licences and franchises.

Deferred Revenues: For purposes of the above quick asset ratio, deferred revenues shall not be counted as current liabilities. For purposes of the above debt to tangible net worth ratio, deferred revenues shall not be counted in determining total liabilities but shall be counted in determining tangible net worth for purposes of such ratio. For all other purposes deferred revenues shall be counted as liabilities in accordance with generally accepted accounting principles. Subordinated Debt: "Liabilities" for purposes of foregoing covenants do not include indebtedness which is subordinated to the indebtedness to Silicon under a subordination agreement in form specified by Silicon or by language in the instrument evidencing the indebtedness which is acceptable to Silicon." 4.

It is understood by the parties hereto, however, that such waiver does not constitute a waiver of any other provision or term of the Loan Agreement or any related document, nor an agreement to waive in the future these covenants or any other provision or term of the Loan Agreement or any related document. 5. Fee. Borrower shall pay to Silicon a fee in the amount of $5,000, which shall be in addition to interest and all other amounts due Silicon and shall not be refundable. 6. Representations True.
