Introductory Note.

On July 7, 2010, DynCorp International Inc., a Delaware corporation (“DynCorp International”), completed its merger (the “Merger”) with Delta Tucker Sub, Inc. (“Merger Sub”), a Delaware corporation and a wholly-owned subsidiary of Delta Tucker Holdings, Inc., a Delaware corporation (“Parent”), pursuant to the Agreement and Plan of Merger dated as of April 11, 2010, by and among DynCorp International, Parent and Merger Sub (the “Merger Agreement”). Pursuant to the Merger Agreement, Merger Sub merged with and into DynCorp International. DynCorp International was the surviving corporation in the Merger (the “Surviving Corporation”) and, as a result of the Merger, became a wholly-owned subsidiary of Parent. Parent and Merger Sub are entities created on behalf of affiliated funds and/or managed accounts of Cerberus Capital Management, L.P., a private investment firm (“Cerberus”). The Merger Consideration (as defined in Item 3.03 below) was funded through equity financing provided by affiliates of Cerberus, borrowings under DynCorp International’s new Senior Credit Facility (as defined in Item 1.01 below), the issuance and sale of the Notes (as defined in Item 1.01 below) and DynCorp International’s cash on hand.

In connection with the Merger, DynCorp International entered into new senior secured credit facilities on July 7, 2010 (the “Senior Credit Facility”), by and among DynCorp International, Parent, the other guarantors party thereto from time to time, Bank of America, N.A., as administrative agent and collateral agent, Banc of America Securities LLC, Citigroup Global Markets Inc., Barclays Capital Inc. and Deutsche Bank Securities Inc., as joint lead arrangers and joint bookrunners and the lenders party thereto from time to time. The Senior Credit Facility consists of a $570 million term loan facility and a $150 million revolving credit facility.

On July 7, 2010, DynCorp International issued $455 million aggregate principal amount of 10.375% Senior Notes due 2017 (the “Notes”) pursuant to the purchase agreement entered into on June 29, 2010 by and among Merger Sub and Banc of America Securities LLC, Citigroup Global Markets Inc., Barclays Capital Inc. and Deutsche Bank Securities Inc., the initial purchasers of the Notes (the “Initial Purchasers”), as amended by the Joinder Agreement dated July 7, 2010, by and among DynCorp International, the Guarantors (as defined below) and the Initial Purchasers. The Notes were issued under an indenture dated as of July 7, 2010, by and among DynCorp International, the guarantors party thereto (the “Guarantors”) and Wilmington Trust FSB, as trustee. The Notes will mature on July 1, 2017. Interest on the Notes is payable on January 1 and July 1 of each year, commencing on January 1, 2011.

On July 7, 2010, DynCorp International and the Guarantors entered into a registration rights agreement with the Initial Purchasers (the “Registration Rights Agreement”) with respect to the Notes. Pursuant to the Registration Rights Agreement, DynCorp International has agreed to cause to become effective a registration statement relating to the offer and exchange of the Notes for registered notes (the “exchange notes”) having identical terms as the Notes (except that the exchange notes will not be subject to restrictions on transfer or to any increase in the interest rate as described in the Registration Rights Agreement).
