At
reasonable times, and on at least one Business Days notice, Silicon, or its agents, shall have the right to inspect the Collateral, and the right to audit and copy Borrowers books and records; provided, however, that, so
long as no Event of Default has occurred and is continuing, audits shall be conducted by Silicon no more often than once every 6 months (it being understood that audits taking place at one or more locations of Borrower during substantially the same
overall examination period shall constitute but a single audit for purposes of the foregoing proviso).

At reasonable times, and on at least one Business Days notice, Silicon, or its agents, shall have the right to inspect the Collateral, and the right
to audit and copy Borrowers books and records. Without limiting the generality of the foregoing, during Phase II, the first audit following the date that Phase II becomes in effect (or, if no Revolving Loans are outstanding on the date that
Phase II becomes in effect, then the first audit following the date on which the first Revolving Loan is made during Phase II) is anticipated to be completed within 30 days following such date, and Silicon shall have the right to conduct subsequent
audits at such frequency as Silicon in its good faith business judgment determines (and in any event no less frequent than once every 6 months).

available funds; and (b) wire transfers, ACH transfers, and cash each shall be deemed applied by Silicon on account of the Obligations the same Business Day as deemed received by Silicon). For purposes of the foregoing, any such funds received after
12:00 Noon on any day shall be deemed received on the next Business Day. Silicon shall not, however, be required to credit Borrowers account for the amount of any item of payment which is unsatisfactory to Silicon in its good faith business
judgment, and Silicon may charge Borrowers loan account for the amount of any item of payment which is returned to Silicon unpaid.



3.Fee.In consideration for Silicon entering into this Amendment and the above-referenced Amended and Restated Schedule, Borrower shall pay
Silicon (in lieu of the $50,000 fee due on June 27, 2005 pursuant to the Loan Agreement, absent giving effect to this Amendment) a fee of $35,000 concurrently with the execution and delivery of this Amendment,
