WHEREAS, the Borrower,
the Lenders and the Administrative Agent have amended the Loan Agreement from time to time to, among other things, adjust the payment dates for certain such principal and interest payments.

WHEREAS, after giving effect to the payment described in Clause 1 below, there is currently accrued and unpaid interest under the Loan Agreement in an amount set forth

periodic cash payments by the Borrower to the Lenders as set forth below.

|4. | The parties hereto hereby agree that $2,400,000 in accrued and unpaid interest under the Loan Agreement set forth in Clause 2 above be capitalized, converted into and considered a
Tranche B1 Loan advanced by the Lenders to the Borrower under the Loan Agreement and that $2,435,564 in accrued and unpaid interest under the Loan Agreement set forth in Clause 2 above be capitalized, converted into and considered a Tranche B2 Loan
advanced by the Lenders to the Borrower under the Loan Agreement.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

principal of Tranche B Loan (made up of $2,400,000 in principal of Tranche B1 Loan and $2,435,564 in principal of Tranche B2 Loan), for an aggregate outstanding principal amount borrowed and due to the Lenders under the Loan Agreement of

|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | The definition of Maturity Date in Section 1.1 of the Loan Agreement, as such definition was amended by the Waiver and Amendment Agreement entered into as of
August 23, 2007 by the parties below, is hereby amended by replacing the phrase (a) with respect to a Loan, April 30, 2009 thereof with the following: (a) with respect to a Tranche A Loan and a Tranche B1 Loan,
January 31, 2010 and with respect to a Tranche B2 Loan, December 15, 2008. As a result, payment in full of the total outstanding $10,000,000 in principal amount of Tranche A Loan and the total outstanding $2,400,000 in principal
amount of Tranche B1 Loan pursuant to the Loan Agreement shall become due and payable on January 31, 2010, and payment in full of the total outstanding $2,435,564 in principal amount of Tranche B2 Loan shall become due and payable on
December 15, 2008. For the avoidance of doubt, any failure to pay any such principal amount when due shall trigger the operation of the provisions of Section 2.3(c) of the Loan Agreement.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | Without prejudice to the terms of Section 2.3(c) of the Loan Agreement, interest shall accrue on the Tranche A Loan and the Tranche B Loan at the Loan Rate from the date
hereof. Notwithstanding any amendment to, or waiver of any obligations or Defaults or Events of Default under, the Loan Agreement to the contrary made prior to the date hereof, the Borrower shall make payments of interest in arrears with respect to
the Tranche A Loan and the Tranche B Loan at the Loan Rate on December 31, 2008 (including, without limitation, all interest which shall have accrued on the Tranche B2 Loan from and after the date hereof) and on each subsequent Payment Date in
accordance with Section 2.1(f) of the Loan Agreement. For the avoidance of doubt, any failure to pay interest when due shall trigger the operation of the provisions of Section 2.3(c) of the Loan Agreement. The Waiver and Amendment
Agreement entered into as of August 23, 2007 by the parties below is hereby amended by deleting clause 3 thereof, and the Amendment Agreement entered into as of October 10, 2007 by the parties below is hereby amended by deleting clauses 1
and 2 thereof.
|-- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | If the Borrower achieves a consolidated EBITDA of US$6.0 million or greater during a fiscal quarter, then the Borrower shall pay to the Lenders an aggregate of
US$600,000 within thirty days of the end of such fiscal quarter, such amount to be applied to and reduce, first, any accrued and unpaid interest and, second, the outstanding principal amount of the Tranche B Loan (in which case such amount shall
first be applied to the outstanding principal amount of the Tranche B2 Loan, if any). For purposes of this Clause 8, EBITDA is defined as net income (loss), before interest expense, income tax (expense) benefit, other income (expense), net,
depreciation of property, plant and equipment and specific charges (representing, to the extent applicable,
