Attn: Robert W. Stockton

Suite 500

Houston, TX 77042

Dear Mr. Stockton:

This letter amends an approval and agreement letter executed by the Fisheries Finance Program on December 1, 2005, and amended on September 14, 2006, approving in principle a $16,442,000 loan to Omega Protein, Inc. (the “Company”). This letter approves the second portion of the loan (the “Second Tranche”). Under the Agreement each disbursement will require the Company’s issuance of a separate promissory note to the United States of America. The Company now requests a disbursement in the amount of $10,000,000 (the “Second Tranche”).

Upon full compliance with this approval and agreement letter (the “Approval Letter”), and otherwise in accordance with the Approval Letter, Subtitle V of Title 46 of the U.S. Code, formerly known as “Title XI of the Merchant Marine Act of 1936,” 46 U.S.C. 53701, et seq., and the Magnuson-Stevens Fishery Conservation and Management Act, 16 U.S.C. Section 1801 et seq., as amended, and the outstanding guidance and instructions of the Financial Services Division, we will issue a United States Promissory Note (the “Second Tranche Note”) and do all things necessary to effect the Second Tranche.

The purpose of the Second Tranche is to finance or refinance 79.60% of the combined $12,562,298 depreciated actual cost of the Company’s reconstruction of a menhaden fishing vessel and the addition of a new dryer at the Reedville, Virginia facility (the “Project”).

(2.1) The Second Tranche Note shall, in form and substance, be similar to our customary form of United States Promissory Note and shall involve the following amount and other basic terms:

(2.2) We shall direct that the proceeds of the Second Tranche Note be paid, first, directly to the parties to whom the Company is indebted for the Project’s eligible cost and, second to the Company (as reimbursement of the Company’s funds previously expended for the Project’s eligible cost) to the extent that the amount of the Second Tranche Note exceeds the amount of the Company’s outstanding indebtedness for the Project’s eligible cost.

(3.1) Security for the Second Tranche Note shall be such security agreements, undertakings, and other documents of whatsoever nature deemed by us, in our sole discretion, necessary to accomplish the intent and purpose of the Approval Letter and otherwise protect our interest (collectively, the “Security Documents”). The Security Documents shall, in form and substance, be similar to our customary form of security documents insofar as such customary form of Security Documents is, in our sole discretion, consistent with and appropriate for the Second Tranche.

(3.2) The Company and the other parties specified below shall, as additional security for the Second Tranche Note, be bound by and subject to the following special requirements, special covenants, and all provisions pertaining to them.
