Complete the box(es) on the reverse side to make tender to receive shares of Abacus Innovations Corporation (“Splitco”) common stock, each of which is subject to proration, adjustment and certain limitations as set forth in the Agreement and Plan of Merger (the “Merger Agreement”) dated as of January 26, 2016, among Lockheed Martin, Splitco, Leidos Holdings, Inc. (“Leidos”) and Lion Merger Co. (“Merger Sub”), and the Prospectus—Offer to Exchange, dated             , 2016 (the “Prospectus”).

This Letter of Transmittal relates to the offer by Lockheed Martin to exchange all shares of common stock of Splitco (“Splitco common stock”) which are owned by Lockheed Martin for shares of common stock of Lockheed Martin (“Lockheed Martin common stock”) that are validly tendered and not properly withdrawn. Immediately following consummation of the exchange offer, Merger Sub, a wholly-owned subsidiary of Leidos, will be merged with and into Splitco, with Splitco as the surviving company and a wholly-owned subsidiary of Leidos (the “Merger”). In the Merger, each share of Splitco common stock will be converted into the right to receive one share of Leidos common

stock. Accordingly, shares of Splitco common stock will not be transferred to participants in the exchange offer; participants instead will receive shares of Leidos common stock in the Merger. As a result, you will not be able to trade shares of Splitco common stock before they convert into Leidos common stock in the Merger. There can be no assurance that Leidos common stock when issued in connection with the Merger will trade at the same prices as Leidos common stock trades prior to the Merger.

Although Lockheed Martin has mailed the Prospectus to the extent required by U.S. law, including to stockholders located outside the United States, the Prospectus is not an offer to buy, sell or exchange and it is not a solicitation of an offer to buy or sell any shares of Lockheed Martin common stock, shares of Leidos common stock or shares of Splitco common stock in any jurisdiction in which such offer, sale or exchange is not permitted. Countries outside the United States generally have their own legal requirements that govern securities offerings made to persons resident in those countries and often impose stringent requirements about the form and content of offers made to the general public. None of Lockheed Martin, Leidos or Splitco has taken any action under non-U.S. laws or regulations to facilitate a public offer to exchange shares of Lockheed Martin common stock, shares of Leidos common stock or shares of Splitco common stock outside the United States. Accordingly, the ability of any non-U.S. person or any U.S. person residing outside of the United States to tender shares of Lockheed Martin common stock in the exchange offer will depend on whether there is an exemption available under the laws of such person’s home country or country of residence, as applicable, that would permit the person to participate in the exchange offer without the need for Lockheed Martin, Leidos or Splitco to take any action to facilitate a public offering in that country. For example, some countries exempt transactions from the rules governing public offerings if they involve persons who meet certain eligibility requirements relating to their status as sophisticated or professional investors. Non-U.S. stockholders and stockholders residing outside of the United States should consult their advisors in considering whether they may participate in the exchange offer in accordance with the laws of their home countries or countries of residence, as applicable, and, if they do participate, whether there are any restrictions or limitations on transactions in the shares of Lockheed Martin common stock, Leidos common stock or Splitco common stock or that may apply in such countries. Lockheed Martin, Leidos, Splitco and the information agent cannot provide any assurance about whether such limitations may exist.
