The Borrower has requested that the Lender make certain amendments to the Credit Agreement, which the Lender is willing to do pursuant to the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants and agreements herein contained, it is agreed as follows:

1. Defined Terms.

(a) Capitalized terms used in this Amendment which are defined in the Credit Agreement shall have the same meanings as defined therein, unless otherwise defined herein.

1

(b) The following definition set forth in Section 1.1 of the Credit Agreement is hereby amended in its entirety as follows:

“Floating Rate” means an annual interest rate equal to the sum of “Daily Three Month LIBOR plus the Margin, which interest rate shall, in each case, change when and as “Daily Three Month LIBOR changes.

(c) The following new definitions are hereby added to Section 1.1 of the Credit Agreement in appropriate alphabetical order:

“EBITDA” means, with respect to any period of determination, Net Income or Net Loss for such period, plus Interest Expense, tax expense, amortization expense, depreciation expense and extraordinary losses and minus extraordinary gains, in each case as determined in accordance with GAAP to the extent included in the determination of such Net Income or Net Loss.

“Minimum Liquidity Amount” means $3,000,000.

“Thirteenth Amendment” means that certain Thirteenth Amendment to Credit and Security Agreement, dated as of January 27, 2010, between the Borrower and the Lender, amending this Agreement.

(d) The following definition set forth in Section 1.1 of the Credit Agreement is hereby deleted: “Wells Fargo Base Rate.”

2. Amendment to Section 2.12(b). Section 2.12(b) of the Credit Agreement is hereby amended in its entirety as follows:

(b) Upon the effectiveness of the Thirteenth Amendment, the Margins shall be four percent (4.00%) for Floating Rate Advances, and four percent (4.00%) for LIBOR Advances. The Margins shall be adjusted as set forth in the table below upon the Borrower achieving EBITDA as set forth in the table below:

2

Any such adjustments shall be effective on the first calendar day of the month following the month of receipt by the Lender of the Borrower’s financial statements delivered pursuant to Section 6.1(b) if, and only if, (i) such financial statements evidence the required EBITDA set forth in the table above, and (ii) on the date that the reduction in the Margins would otherwise be effective, no Event of Default has occurred and is continuing. If the Borrower fails to timely deliver financial statements as agreed, no reduction in Margins shall be made and the Lender may notify the Borrower that an Event of Default has occurred and adjust the Margins to 4.00%, and impose the Default Rate.

If amended or restated financial statements would change previously calculated Margins, or if the Lender determines that any financial statements have materially misstated the Borrower’s financial condition, then the Lender may, using the most accurate information available to it, recalculate the financial test or tests governing the Margins and retroactively increase the Margins from the date of receipt of such amended or restated financial statements and charge the Borrower additional interest, which may be imposed on it from the beginning of the appropriate month to which the restated statements or recalculated financial tests relate or to the beginning of the fiscal quarter in which any Event of Default has occurred, as Lender in its sole discretion deems appropriate.

3. Amendments to Sections 2.13(f) and (g). Sections 2.13(f) and (g) of the Credit Agreement are hereby amended in their entirety as follows:

(f) Termination and Line Reduction Fees. If the Credit Facility is terminated (i) by the Lender during a Default Period, (ii) by the Borrower (A) as of a date other than the Maturity Date or (B) as of the Maturity Date but without the Lender having received written notice of such termination at least 90 days before the Maturity Date, or if the Borrower reduces the Maximum Line, the Borrower shall pay to the Lender a fee in an amount equal to a percentage of the Maximum Line (or the reduction of the Maximum Line, as the case may be) as follows: (A) two and one-half percent (2.50%) if the termination or reduction occurs on or before June 2, 2010; and (B) one and one-half percent (1.50%) if the termination or reduction occurs anytime thereafter.

(g) Contracted Funds Breakage Fees. The Borrower may prepay the principal amount of the Revolving Note at any time, whether voluntarily or by acceleration, provided, however, that if the principal amount of any Revolving Note LIBOR Advance is prepaid, the Borrower shall pay to the Lender immediately upon demand a contracted funds breakage fee equal to the sum of the discounted monthly differences for each month from the month of prepayment through the month in which such Interest Period matures, calculated as follows for each such month:

(i) Determine the amount of interest which would have accrued each month on the amount prepaid at the LIBOR Advance rate applicable

3

to such amount had it remained outstanding until the last day of the applicable Interest Period.

(ii) Subtract from the amount determined in (i) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such Interest Period at LIBOR in effect on the date of prepayment for new loans made for such term in a principal amount equal to the amount prepaid.

(iii) If the result obtained in (ii) for any month is greater than zero, discount that difference by LIBOR used in (ii) above.

Borrower acknowledges that a prepayment may result in Lender incurring additional costs, expenses and/or liabilities, and that it is difficult to ascertain the full extent of such costs, expenses and/or liabilities. Borrower therefore agrees to pay the above-described prepayment fee and agrees that said prepayment fee represents a reasonable estimate of the prepayment costs, expenses and/or liabilities of the Lender.

4. Amendment to Section 6.2. A new clause (e) is hereby added to Section 6.2 of the Credit Agreement immediately following clause (d) thereof as follows:

(e) Minimum Liquidity. Commencing January 1, 2010, the Borrower shall not permit the sum of Availability plus cash on hand at any time to be less than the Minimum Liquidity Amount, tested monthly.

5. Amendment to Section 6.6(d). Section 6.6(d) of the Credit Agreement is hereby amended in its entirety as follows:

(d) an investment in a Subsidiary to be organized under the laws of Hong Kong.

6. Replacement of Exhibit C. Exhibit C attached to the Credit Agreement is hereby replaced with Exhibit C attached to this Amendment.

7. No Other Changes. All of the terms and conditions of the Credit Agreement and the Loan Documents as amended by this Amendment shall remain in full force and effect.

8. Amendment Fee. The Borrower shall pay the Lender as of the date hereof a fully earned, non-refundable fee in the amount of $30,000 (“Amendment Fee”) in consideration of the Lender’s execution and delivery of this Amendment. The Amendment Fee shall be due and payable upon execution of this Amendment.

It is the intention of the Borrower, the Guarantor and each Subordinated Creditor in providing this release that the same shall be effective as a bar to each and every claim, demand and cause of action specified, and in furtherance of this intention it waives and relinquishes all rights and benefits under Section 1542 of the Civil Code of the State of California, which provides:

The Borrower hereby agrees that the Lender may, at any time or from time to time in its sole discretion and without further authorization by the Borrower, make a loan to the Borrower under the Credit Agreement, or apply the proceeds of any loan, for the purpose of paying any such fees, disbursements, costs and expenses, and the Amendment Fee.

15. Miscellaneous. This Amendment, the Acknowledgement and Agreement of Guarantor, and the Acknowledgment and Agreement of Subordinated Creditors may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original and all of which counterparts, taken together, shall constitute one and the same instrument.
