W I T N E S S E T H:

WHEREAS, Bank and Borrowers have entered into that certain Loan and Security Agreement dated as of December 20, 2000 (as amended, restated, modified or supplemented from time to time, the “Loan Agreement”); and

WHEREAS, the Guarantors, together with Protein Operating Company, a Delaware corporation (“POC”), Protein Securities Company, a Delaware corporation (“PSC”), and Protein (U.S.A.) Company, a Delaware corporation (“Protein USA”; POC, PSC and Protein USA are herein after collectively referred to as the “Former Protein Subsidiaries”); entered into that certain Unconditional Guaranty in favor of Bank dated as of December 20, 2000 (as amended, restated, modified or supplemented from time to time, the “Guaranty”), pursuant to which the Guarantors and the Former Protein Subsidiaries guaranteed to Bank the payment of all obligations of Borrowers to Bank however arising, including, without limitation, amounts due under the Loan Agreement; and

NOW, THEREFORE, in consideration of the foregoing premises, and other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

All capitalized terms used herein and not otherwise expressly defined herein shall have the respective meanings given to such terms in the Loan Agreement.

The Loan Agreement is amended by deleting the reference to “$12,000,000” in Section 2(a)(ii)(1) and inserting “$10,000,000” in lieu thereof.

The Loan Agreement is amended by deleting Sections 2(k) and substituting the following in lieu thereof:

(k) Contribution and Indemnification among Borrowers. Each Borrower is obligated to repay the Secured Obligations as joint and several obligors under this Agreement. To the extent that any Borrower shall, under this Agreement as a joint and several obligor, repay any of the Secured Obligations constituting Revolving Loans made to the other Borrower hereunder or other Secured Obligations incurred directly and primarily by the other Borrower (an “Accommodation Payment”), then the Borrower making such Accommodation Payment shall be entitled to contribution and indemnification from, and be reimbursed by, the other Borrower in an amount equal to such other Borrower’s “Allocable Amount” (as defined below). As of any date of determination, the “Allocable Amount” of each Borrower shall be equal to the maximum amount of liability for Accommodation Payments which could be asserted against such Borrower hereunder without (i) rendering such Borrower “insolvent” within the meaning of Section 101(31) of Title 11 of the United States Code (the “Bankruptcy Code”), Section 2 of the Uniform Fraudulent Transfer Act (the “UFTA”), or Section 2 of the Uniform Fraudulent Conveyance Act (“UFCA”), (ii) leaving such Borrower with unreasonably small capital or assets, within the meaning of Section 548 of the Bankruptcy Code, Section 4 of the UFTA, or Section 4 of the UFCA, or (iii) leaving such Borrower unable to pay its debts as they become due within the meaning of Section 548 of the Bankruptcy Code, Section 4 of the UFTA, or Section 5 of the UFCA. All rights and claims of contribution, indemnification and reimbursement under this paragraph shall be subordinate in right of payment to the prior payment in full of the Secured Obligations.

The Loan Agreement is amended by deleting Section 4(c)(ii) and inserting the following in lieu thereof:

(ii) Commitment Fee. Borrower shall pay to Bank a commitment fee at the per annum rate of 0.375% multiplied by the actual daily amount of the Availability. The commitment fee shall accrue at all times through and including the Termination Date and shall be due and payable quarterly in arrears on (a) the last Business Day of each September, December, March, and June commencing with December 31, 2005, and (b) the Maturity Date.

The Loan Agreement is amended by deleting Section 4(d) and substituting the following in lieu thereof:

(d) Usury. Regardless of any provision contained in any Loan Document, if the Bank shall ever be entitled to contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the Loan, any amount in excess of the Maximum Rate, and, the Bank ever does so, then such excess shall be deemed a partial prepayment of principal and treated hereunder as such and any remaining excess shall be refunded to the Borrowers. In determining if the interest paid or payable exceeds the Maximum Rate, the Borrowers and the Bank shall, to the maximum extent permitted under applicable Law, (a) treat all extensions of credit to the Borrowers by the Bank as but a single extension of credit (and the Bank and the Borrowers agree that such is the case and that provision herein for multiple extensions of credit is for convenience only), (b) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments and the effects thereof, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Loan. However, if the Loan is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Amount, the Bank shall refund such excess, and, in such event, the Bank shall not, to the maximum extent permitted by applicable law, be subject to any penalties provided by any such laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Maximum Amount. If the laws of the State of Texas are applicable for purposes of determining the “Maximum Rate” or the “Maximum Amount,” then those terms mean the “weekly ceiling” from time to time in effect under Texas Finance Code § 303.305, as amended (the Texas Finance Code is referred to herein as the “Act”). The Borrowers agree that Chapter 346 of the Texas Finance Code, as amended (which regulates certain revolving credit loan accounts and revolving tri-party accounts), does not apply to the Loan.

The interest rates provided for in Section 4(a) shall be computed on the basis of a year of 360 days and the actual number of days elapsed; provided, however, any calculation of the Maximum Rate shall be computed on the basis of the actual days elapsed in a year of 365 or 366 days as appropriate, unless the Act permits any applicable interest rate ceiling to be calculated on the basis of a 360-day year and twelve 30-day months.

The Loan Agreement is amended by deleting Sections 6(a), 6(b) and 6(c) and substituting the following in lieu thereof:

(a) Fixed Charge Coverage Ratio. Permit the Fixed Charge Coverage Ratio for the Borrowers and their Subsidiaries, on a consolidated basis, to be less than 1.25 to 1, as measured on a quarterly basis using the consolidated results of the four fiscal quarter period ending with the applicable reporting period as required by Section 9(a)(2).

(b) Minimum Net Income. Permit the net income (in accordance with GAAP) of the Borrowers and their Subsidiaries, on a consolidated basis, to be less than $0.00 for any two (2) consecutive fiscal quarters of the Parent.

(2) Quarterly Financial Statements. As soon as available, but in any event within 45 days after the end of each fiscal quarter of each fiscal year of Parent, Borrowers will deliver to the Bank a consolidated [and consolidating] balance sheet of Parent and its Subsidiaries as at the end of such fiscal quarter, and the related consolidated [and consolidating] statements of income or operations, Shareholders’ Equity and cash flows for such fiscal quarter and for the portion of Parent’s fiscal year then ended, setting forth in each case in comparative form the figures for the corresponding fiscal quarter of the previous fiscal year and the corresponding portion of the previous fiscal year, all in reasonable detail and certified by a Responsible Officer of Parent as fairly presenting the financial condition, results of operations, Shareholders’ Equity and cash flows of Parent and its Subsidiaries in accordance with GAAP, subject only to normal year-end audit adjustments and the absence of footnotes.

The Loan Agreement is amended by deleting Section 9(a)(4) and inserting the following in lieu thereof:

outstanding principal balance on any Revolving Loan, at least quarterly within forty-five (45) days of the end of each calendar quarter, (1) a borrowing base certificate, in form acceptable to Bank, specifying the book value of the Collateral as of the last day of the preceding week and identifying any items of Collateral as to which a representation, covenant or, in the case of Receivables, any condition set forth in Section 2(a)(i) is not true, (2) a detailed aging of Receivables and an accounts payable aging, both prepared as of the last day of such calendar quarter end and in such form as required by Bank, including the names and addresses of Borrowers’ Customers and (3) a detailed inventory report listing locations of Inventory and the types and values of Inventory at each such location, in such form as Bank may require. Borrowers will also conduct a physical inventory count each year and adjust its records to reflect the results of the count. At Bank’s request, Borrowers shall deliver such information more or less often than described above and such other information with respect to the collateral as Bank may reasonably request.

The Loan Agreement is amended by deleting Section 15(a) and substituting the following in lieu thereof:
