General

This announcement is being made in connection with the proposed acquisition of Maconomy by Deltek. This announcement does not constitute an offer or invitation to acquire or exchange securities in Deltek or Maconomy in the United States, in any state or in any other jurisdiction pursuant to the tender offer or otherwise. The solicitation and the offer to buy Maconomy shares will be made only pursuant to an offer document, including the acceptance form attached thereto (collectively, the “Offer Document”) filed with the Danish Financial Supervisory Authority (the “DFSA”). Maconomy shareholders are urged to read the Offer Document carefully and in its entirety because it contains important information about the tender offer.

The tender offer will be made solely through the Offer Document, which will provide and contain the full terms and conditions of the tender offer, including details of how to tender Maconomy shares. Any response to the tender offer should be made only on the basis of the information contained in the Offer Document.

The tender offer will not be made, directly or indirectly, in or into Australia, Canada or Japan and will not be capable of acceptance from within Australia, Canada or Japan. Accordingly, copies of this announcement and all other documents relating to the tender offer are not being, and must not be, mailed or otherwise forwarded, distributed or sent in, into or from Australia, Canada or Japan. Persons receiving such documents (including, without limitation, nominees, trustees and custodians) should observe these restrictions and must not mail or otherwise forward, distribute or send such documents in, into or from Australia, Canada or Japan. Doing so may invalidate any related purported acceptance of the tender offer.

The implications of the tender offer for Maconomy shareholders may be affected by the laws of the relevant jurisdictions. Maconomy shareholders should inform themselves about and observe any applicable legal requirements. It is the responsibility of each Maconomy shareholder to satisfy himself or herself as to the full observance of the laws of the relevant jurisdiction in connection therewith, including the obtaining of any governmental, exchange control or other consents which may be required to be observed and the payment of any issue, transfer or other taxes in such jurisdictions. The distribution of this announcement in jurisdictions other than Denmark and the United States may be restricted by law and therefore persons in such jurisdictions into whose possession this announcement comes should inform themselves about and observe such restrictions.

For U.S. securities law purposes, the tender offer described in this announcement will be made for the securities of a foreign company by means of a voluntary offer in accordance with the Danish Securities Trading Act (Consolidation Act No. 795 of 20 August 2009 as subsequently amended) and Executive Order No. 221 of 10 March 2010 on Takeover Bids issued by the DFSA. The tender offer is subject to disclosure and procedural requirements of a foreign country that are different from those of the United States. Financial statements relating to Maconomy included in this press release or incorporated in the Offer Document are prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of United States companies.

It may be difficult to enforce your rights and any claim that one may have arising under United States federal securities laws, since Maconomy is located in a foreign country, and some or all of its officers and directors may be residents of a foreign country. You may not be able to sue Maconomy or its officers or directors in a foreign court for violations of the U.S. securities laws. It may be difficult to compel Maconomy and its affiliates to subject themselves to a U.S. court’s judgment.

Investors should be aware that Deltek may purchase securities otherwise than pursuant to the tender offer, such as in the open market or privately negotiated purchases.

Forward-Looking Statements

This announcement contains “forward-looking statements” with respect to certain of Deltek’s and/or Maconomy’s plans and their current goals and expectations relating to their future financial condition, performance and results and other similar matters. Forward-looking statements may be identified by words such as “believe,” “belief,” “expect,” “intend,” “may,” “plan,” “should,” “would” or other similar words. By their nature, forward-looking statements involve substantial risk and uncertainties because they relate to future events and circumstances which Deltek or Maconomy are not able to accurately predict or which are beyond the control of Deltek and/or Maconomy, including amongst other things, U.S. and Danish domestic and global economic business conditions, market-related risks such as fluctuations in interest rates and exchange rates, the policies and actions of regulatory authorities, the impact of competition, inflation, deflation, the timing impact and other uncertainties of future acquisitions or combinations within relevant industries, as well as the impact of tax and other legislation and other regulations in the jurisdictions in which Deltek, Maconomy or their respective affiliates operate. As a result, the actual future financial condition, performance and results of Deltek or Maconomy may differ materially from the plans, goals and expectations set forth in any forward-looking statements. Before making a decision to tender Maconomy shares in the tender offer, Maconomy shareholders should be aware that the occurrence of any such event (or any of the additional events described as risk factors in Deltek’s filings with the U.S. Securities and Exchange Commission) could have a material adverse effect on Deltek’s and/or Maconomy’s future financial conditions, performance and results. Any forward-looking statement made by either Deltek or Maconomy speaks only as of the date of the Offer Document. Neither Deltek nor Maconomy undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, save in respect of any requirement under applicable laws, rules or regulations.
