Item 1.01 Entry into a Material Definitive Agreement

On July 31, 2014 Alion Science and Technology Corporation (the “Company” or “Alion”)  entered into a First Amendment to Second Amended and Restated Credit Agreement (the “Amendment”) to extend the Maturity Date of the Second Amended and Restated Credit Agreement dated as of May 2, 2014 by and among Alion, Wells Fargo Bank National Association, as administrative agent, and the lenders party thereto (the “Credit Agreement”).  The Amendment extends the Maturity Date of the Credit Agreement to the earlier of (a) August 15, 2014, (b) the date on which Alion’s secured notes due November 2014 become due and payable in full whether by acceleration or otherwise, and (c) the date on which Alion’s unsecured notes due February 2015 become due and payable in full whether by acceleration or otherwise.

A copy of the Amendment is attached to this current report on Form 8-K as Exhibit 10.48 and it is incorporated by reference as though it were fully set forth herein. The foregoing summary description of the Amendment and the transactions contemplated thereby is not intended to be complete, and it is qualified in its entirety by the complete text of the Amendment.

The Company has filed a registration statement on Form S-1 (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) relating to an offer to exchange its existing unsecured notes due February 2015 for new securities (the “Exchange Offer”), but it has not yet been declared effective by the SEC. Security holders and investors are urged to read the Registration Statement and any amendments to the Registration Statement because they contain important information regarding the contemplated Exchange Offer. Security holders and investors are able to obtain copies of any documents filed with the SEC regarding the Exchange Offer, free of charge, at the SEC’s website (www.sec.gov), at the Company’s website (www.alionscience.com) or by contacting Alion Science and Technology Corporation, 1750 Tysons Boulevard, Suite 1300, McLean, Virginia 22102, (703) 918-4480, Attention: Kevin Boyle, Senior Vice President, General Counsel & Secretary.

This Form 8-K does not constitute an offer to sell or exchange any securities nor specifically does it constitute a solicitation of the Exchange Offer, nor shall there be any sale or exchange of any securities in any state or other jurisdiction in which such offer, solicitation or sale or exchange would be unlawful prior to the registration or qualification of any such securities or offer under the securities laws of any such state or other jurisdiction. The Exchange Offer will be made only through a registration statement under the Securities Act of 1933, as amended, and related materials.
