R E C I T A L S:

WHEREAS, Borrower and Lender entered into a Letter Loan Agreement dated October 31, 2007 (which as the same may have been or may hereafter be amended from time to time is herein called the “Loan Agreement”; the terms defined therein being used herein as therein defined unless otherwise defined herein); and

WHEREAS, Borrower and Lender desire to amend the Loan Agreement to extend the Maturity Date and amend certain terms and provisions of the Loan Agreement.

A G R E E M E N T:

1. Amendments to the Loan Agreement. The Loan Agreement is, effective the date hereof, and subject to the satisfaction of the conditions precedent set forth in Section 2 hereof, hereby amended as follows:

(a) Section 1 of the Loan Agreement is hereby amended in its entirety to read as follows:

“(a) Commitment. Subject to the terms and conditions set forth herein, Lender agrees to make loans (each of which is a “Loan”, and collectively the “Loans”) to Borrower, on a revolving basis (the “Borrowing Base Facility”) from time to time during the period commencing on the date hereof and continuing through July 1, 2011 (the “Maturity Date”), the maturity date of the promissory note evidencing the Borrowing Base Facility, such amounts as Borrower may request hereunder; provided, however, the total principal amount (the “Borrower’s Loan Limit”) outstanding at any time shall not exceed the lesser of (i) an amount equal to the Borrowing Base and (ii) $10,000,000 minus the aggregate face amount of any Letters of Credit. Subject to the terms and conditions hereof, Borrower may borrow, repay and reborrow hereunder. If at any time the outstanding advances under the Borrowing Base Facility exceed the Borrower’s Loan Limit as shown on any reports delivered to Lender under Section 6(d)(ii) or as indicated by Lender’s own records, Borrower shall, on the date of the delivery of such report to Lender or on the date of notice from Lender as to Lender’s records, prepay on the Borrowing Base Facility such amount as may be necessary to eliminate such excess, plus all accrued but unpaid interest thereon. The sums advanced under the Borrowing Base Facility shall be used for general corporate purposes and working capital. As used in this Agreement, the term “Borrowing Base” shall have the meaning set forth in Exhibit A attached hereto.

(b) Interest Rates. The Advance(s) evidenced by this Agreement may be drawn down and remain outstanding as up to five (5) LIBOR Rate Advances

Second Amendment to Loan Agreement – Page 1

and/or a CB Floating Rate Advance. Borrower shall pay interest to Lender on the outstanding and unpaid principal amount of each CB Floating Rate Advance at the CB Floating Rate plus the Applicable Margin and each LIBOR Rate Advance at the Adjusted LIBOR Rate. Interest shall be calculated on the basis of the actual number of days elapsed in a year of 360 days, unless that calculation would result in a usurious interest rate, in which case interest will be calculated on the basis of a 365 or 366 day year, as the case may be. In no event shall the interest rate applicable to any Advance exceed the maximum rate allowed by law. Any interest payment which would for any reason be deemed unlawful under applicable law shall be applied to principal.

(c) Notice and Manner of Electing Interest Rates on Advances. Borrower shall give Lender written notice (effective upon receipt) of Borrower’s intent to draw down an Advance under this Agreement no later than 2:00 p.m. Central time, on the date of disbursement, if the full amount of the drawn Advance is to be disbursed as a CB Floating Rate Advance and no later than 11:00 a.m. Central time three (3) Business Days before disbursement, if any part of such Advance is to be disbursed as a LIBOR Rate Advance. Borrower’s notice must specify: (i) the disbursement date, (ii) the amount of each Advance, (iii) the type of each Advance (CB Floating Rate Advance or LIBOR Rate Advance), and (iv) for each LIBOR Rate Advance, the duration of the applicable Interest Period; provided, however, that Borrower may not elect an Interest Period ending after the Maturity Date. Each LIBOR Rate Advance shall be in a minimum amount of $100,000. All notices under this subparagraph are irrevocable. By Lender’s close of business on the disbursement date and upon fulfillment of the conditions set forth herein and in any other of the Loan Documents, Lender shall disburse the requested Advances in immediately available funds by crediting the amount of such Advances to Borrower’s account with Lender.

(d) Conversion and Renewals. Borrower may elect from time to time to convert one type of Advance into another or to renew any Advance by giving Lender written notice no later than 2:00 p.m. Central time, on the date of the conversion into or renewal of a CB Floating Rate Advance and 11 a.m. Central time three (3) Business Days before conversion into or renewal of a LIBOR Rate Advance, specifying: (i) the renewal or conversion date, (ii) the amount of the Advance to be converted or renewed, (iii) in the case of conversion, the type of Advance to be converted into (CB Floating Rate Advance or LIBOR Rate Advance), and (iv) in the case of renewals of or conversion into a LIBOR Rate Advance, the applicable Interest Period, provided that (1) the minimum principal amount of each LIBOR Rate Advance outstanding after a renewal or conversion shall be $100,000; (2) a LIBOR Rate Advance can only be converted on the last day of the Interest Period for the Advance; and (3) Borrower may not elect an Interest Period ending after the Maturity Date. All notices given under this subparagraph are irrevocable. If Borrower fails to give Lender the notice specified above for the renewal or conversion of a LIBOR Rate Advance by 11:00 a.m. Central time three (3) Business Days before the end of the Interest Period for that Advance, the Advance shall automatically be converted to a CB Floating Rate Advance on the last day of the Interest Period for the Advance.

Second Amendment to Loan Agreement – Page 2

(e) Interest Payments. Interest on the Advances shall be paid as follows:

(i) For each CB Floating Rate Advance, on the last day of each month beginning with the first month following disbursement of the Advance or following conversion of an Advance into a CB Floating Rate Advance, and at the maturity or conversion of the Advance into a LIBOR Rate Advance; and

(ii) For each LIBOR Rate Advance, on the last day of the Interest Period for the Advance and, if the Interest Period is longer than three (3) months, at three-month intervals beginning with the day three (3) months from the date the Advance is disbursed.

(f) Prepayments and Funding Loss Indemnification. Borrower may prepay all or any part of any CB Floating Rate Advance at any time without premium or penalty. Borrower shall pay Lender amounts sufficient (in Lender’s reasonable opinion) to compensate Lender for any loss, cost, or expense incurred as a result of:

(i) Any payment of a LIBOR Rate Advance on a date other than the last day of the Interest Period for the Advance, including, without limitation, acceleration of the Advances by Lender pursuant to this Agreement or the other Loan Documents; or

(ii) Any failure by Borrower to borrow or renew a LIBOR Rate Advance on the date specified in the relevant notice from Borrower to Lender.

(g) Principal Payments. Borrower promises to pay all Advances then outstanding on the Maturity Date.

(h) Default Rate of Interest. After an Event of Default has occurred, whether or not Lender elects to accelerate the maturity of the Note because of such Event of Default, all Advances outstanding under this Agreement shall bear interest at a per annum rate equal to the interest rate being charged on the Advance plus 3% (the “Default Rate”) from the date Lender elects to impose such rate. Imposition of such rate shall not affect any limitations contained in this Agreement on Borrower’s right to repay principal on any LIBOR Rate Advance before the expiration of the Interest Period for that Advance.

(i) Additional Costs. If any applicable domestic or foreign law, treaty, government rule or regulation now or later in effect (whether or not it now applies to Lender) or the interpretation or administration thereof by a governmental authority charged with such interpretation or administration, or compliance by Lender with any guideline, request or directive of such an authority (whether or not having the force of law), shall (1) affect the basis of taxation of payments to Lender of any amounts payable by Borrower under this Agreement or the other Loan Documents (other than taxes imposed on the overall net income of Lender

Second Amendment to Loan Agreement – Page 3

by the jurisdiction or by any political subdivision or taxing authority of the jurisdiction in which Lender has its principal office), or (2) impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, Federal Deposit Insurance Corporation deposit insurance premiums or assessments) against assets of, deposits with or for the account of, or credit extended by Lender, or (3) impose any other condition with respect to this Agreement or the other Loan Documents and the result of any of the foregoing is to increase the cost to Lender of extending, maintaining or funding any Advance or to reduce the amount of any sum receivable by Lender on any Advance, or (4) affect the amount of capital required or expected to be maintained by Lender (or any corporation controlling Lender) and Lender determines that the amount of such capital is increased by or based upon the existence of Lender’s obligations under this Agreement or the other Loan Documents and the increase has the effect of reducing the rate of return on Lender’s (or its controlling corporation’s) capital as a consequence of the obligations under this Agreement or the other Loan Documents to a level below that which Lender (or its controlling corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy) by an amount deemed by Lender to be material, then Borrower shall pay to Lender, from time to time, upon request by Lender, additional amounts sufficient to compensate Lender for the increased cost or reduced sum receivable. Whenever Lender shall learn of circumstances described in this section which are likely to result in additional costs to Borrower, Lender shall give prompt written notice to Borrower of the basis for and the estimated amount of any such anticipated additional costs. A statement as to the amount of the increased cost or reduced sum receivable, prepared in good faith and in reasonable detail by Lender and submitted by Lender to Borrower, shall be conclusive and binding for all purposes absent manifest error in computation.

(j) Illegality. If any applicable domestic or foreign law, treaty, rule or regulation now or later in effect (whether or not it now applies to Lender) or the interpretation or administration thereof by a governmental authority charged with such interpretation or administration, or compliance by Lender with any guideline, request or directive of such an authority (whether or not having the force of law), shall make it unlawful or impossible for Lender to maintain or fund the LIBOR Rate Advances, then, upon notice to Borrower by Lender, the outstanding principal amount of the LIBOR Rate Advances, together with accrued interest and any other amounts payable to Lender under this Agreement or the other Loan Documents on account of the LIBOR Rate Advances shall be repaid (i) immediately upon Lender’s demand if such change or compliance with such requests, in Lender’s judgment, requires immediate repayment, or (ii) at the expiration of the last Interest Period to expire before the effective date of any such change or request provided, however, that subject to the terms and conditions of this Agreement and the other Loan Documents Borrower shall be entitled to simultaneously replace the entire outstanding balance of any LIBOR Rate Advance repaid in accordance with this section with a CB Floating Rate Advance in the same amount.

Second Amendment to Loan Agreement – Page 4

(k) Inability to Determine Interest Rate. If Lender determines that (i) quotations of interest rates for the relevant deposits referred to in the definition of Adjusted LIBOR Rate are not being provided in the relevant amounts or for the relevant maturities for purposes of determining the interest rate on a LIBOR Rate Advance as provided in this Agreement, or (ii) the relevant interest rates referred to in the definition of Adjusted LIBOR Rate do not accurately cover the cost to Lender of making, funding or maintaining LIBOR Rate Advances, then Lender shall, at Lender’s option, give notice of such circumstances to Borrower, whereupon (1) the obligation of Lender to make LIBOR Rate Advances shall be suspended until Lender notifies Borrower that the circumstances giving rise to the suspension no longer exists and (2) Borrower shall repay in full the then outstanding principal amount of each LIBOR Rate Advance, together with accrued interest, on the last day of the then current Interest Period applicable to the LIBOR Rate Advance; provided, however, that, subject to the terms and conditions of this Agreement and the other Loan Documents, Borrower shall be entitled to simultaneously replace the entire outstanding balance of any LIBOR Rate Advance repaid in accordance with this section with an Advance bearing interest at the CB Floating Rate plus the Applicable Margin for CB Floating Rate Advances in the same amount. If the Lender determines on any day that quotations of interest rates for the relevant deposits referred to in the definition of Adjusted One Month LIBOR Rate are not being provided for purposes of determining the interest rate on any CB Floating Rate Advance on any day, then each CB Floating Rate Advance shall hear interest at the Prime Rate plus the Applicable Margin for CB Floating Rate Advances until Lender determines that quotations of interest rates for the relevant deposits referred to in the definition of Adjusted One Month LIBOR Rate are being provided.

(l) Obligations Due on Non-Business Day. Whenever any payment under this Agreement becomes due and payable on a day that is not a Business Day, if no Event of Default then exists, the maturity of the payment shall be extended to the next succeeding Business Day, except, in the case of a LIBOR Rate Advance, if the result of the extension would be to extend the payment into another calendar month, the payment must be made on the immediately preceding Business Day.

(m) Application of Payments. Payments shall be allocated among principal, interest and fees at the discretion of Lender unless otherwise agreed or required by applicable law. Acceptance by Lender of any payment which is less than the payment due at the time shall not constitute a waiver of Lender’s right to receive payment in full at that time or any other time.

(n) Commitment Fee. In consideration of Lender’s commitment to make Advances, Borrower will pay to Lender a commitment fee (the “Commitment Fee”) determined on a daily basis by applying 0.30% per annum to the unused portion of the Borrower’s Loan Limit on each day during the term of the Borrowing Base Facility, determined for each such day by deducting from the amount of the Borrower’s Loan Limit at the end of such day the Facility Usage. For the purposes of this subparagraph (n), the term “Facility Usage” mean the

Second Amendment to Loan Agreement – Page 5

aggregate amount of outstanding Advances under the Borrowing Base Facility. The Commitment Fee shall be due and payable quarterly in arrears on the last day of each March, June, September and December, commencing on June 30, 2009, and at the Maturity Date.”

(b) The definition of “Consolidated Tangible Net Worth” in Section 8(a) of the Loan Agreement is hereby amended in its entirety to read as follows:

“Consolidated Tangible Net Worth” means all of Borrower’s and its Subsidiaries’ assets less the sum of (i) the aggregate book value of Consolidated Intangible Assets, (ii) advances to and investments in joint ventures, (iii) accounts receivable from the holders of equity interests and Borrower’s Affiliates and (iv) Consolidated Total Liabilities.”

(c) Subparagraph (ii) of Section 8(b) of the Loan Agreement is hereby amended in its entirety to read as follows:

“(ii) Total Liabilities to Tangible Net Worth Ratio. Permit, as of the end of each calendar quarter, the ratio of its Consolidated Total Liabilities (excluding any Subordinated Debt) to Consolidated Tangible Net Worth to be more than 1.50 to 1.”
