Exhibit 1 SAVE ATG ----------------- -------------- --------------- -------------- ---------------- Home Rationale SEC Filings News Contact ----------------- -------------- --------------- -------------- ---------------- WELCOME During the 10+ year history of ATG, members of the MWTG Group have worked with ATG's customers and worked in industry implementing solutions on the ATG platform. Most recently, a group advised by MWTG has become one of ATG's largest stockholders. We strongly believe in the Company's greatest assets - its customer base, strong product innovations and high customer loyalty - and we believe these assets should be protected and profitably enhanced. We have always had enormous respect for ATG, for the outstanding achievements of its employees and for the culture of innovation and integrity that has contributed to its success. As a stockholder of ATG, we believe that the ATG board owes a duty to pursue stockholder value and to guide ATG to profitable growth for the benefit of its stockholders. Our decision to solicit your proxy is entirely motivated by what we believe is in the best interests of stockholders from a financial perspective. Our opposition is based on our commitment to stockholder value and our belief, which we believe is shared by many other stockholders, that the proposed merger, under the plan management has proposed, is not in the best interests of ATG's stockholders. To that end, we are soliciting your proxy to vote AGAINST the proposed merger. -------------------------------------------------------------------------------- MITCHELL-WRIGHT TECHNOLOGY GROUP, LLC, MITCHELL-WRIGHT, LLC, SSH PARTNERS I, LP, ARCADIA PARTNERS, L.P., ARCADIA CAPITAL MANAGEMENT, LLC, JAMES DENNEDY AND RICHARD ROFE ARE PARTICIPANTS IN A SOLICITATION OF PROXIES FROM THE SHAREHOLDERS OF ART TECHNOLOGY GROUP, INC.

SAVE ATG ----------------- -------------- --------------- -------------- ---------------- Home Rationale SEC Filings News Contact ----------------- -------------- --------------- -------------- ---------------- RATIONALE The following is a summary of what we believe to be the consequences of the proposed merger. They are the primary reasons why we believe stockholders should vote AGAINST the issuance of shares of ATG common stock in connection with the proposed merger. ATG'S FINANCIAL POSITION WILL DETERIORATE. In our opinion, neither ATG nor Primus has demonstrated a management culture or commitment to profitability. The proposed merger combines two companies with a history of losses. The combination creates an entity with merely the possibility of greater revenue but with the CERTAINTY of increased operating expenses. Should the additional revenue expected by management from the merger fail to materialize or the full level of cost reductions not be implemented, ATG's cash balance would quickly erode to a level well below the $30 million cash level cited by management as a critical threshold. ATG'S STRATEGIC POSITION WILL NOT MATERIALLY IMPROVE. While the proposed merger would enhance ATG's product portfolio, ATG would still be a software company with less than $100 million of revenue on an enterprise basis. ATG would still lack the size and breadth of offering required to be truly competitive in the software industry. In addition, the weak financial position that we believe would result from the merger would limit ATG's strategic options in the future. THE INTEGRATION RISK OF THE PROPOSED MERGER IS SUBSTANTIAL. We believe that the odds are against the success of this merger given management's post-merger operating plan. The complexity of putting two companies together, in a difficult economy, when each company is unable to consistently produce profits, presents daunting and unacceptable challenges. THE FINANCIAL IMPACT ON ATG STOCKHOLDERS WILL BE NEGATIVE. Management has asked shareholders to accept tremendous risk by approving the merger agreement without, in our opinion, providing an action plan that would produce financial results to justify the additional financial risk, operating risk and dilution that would result from the merger. ATG has several valuable assets - its customer base, strong product innovations, and high customer loyalty. We believe these assets should be protected and profitably enhanced. The company faces challenges in managing its business, but these challenges were known before this transaction, and management needs to focus all of its attention on resolving them. We profoundly disagree, however, with management's assertion that ATG needs to make this acquisition. To undertake the proposed merger under the currently proposed plan is to wager that management can grow revenue in time to cover the company's cost structure. We have seen little in ATG's management's experience that leads us to believe that this is possible. Instead, we believe that the proposed merger deteriorates the financial position of ATG and does not solve key strategic problems. It creates immediate risk and intermediate-term incremental challenges, and we believe it comes at a high price to ATG stockholders. We do not believe that ATG should stand still. On the contrary, we believe that ATG would benefit greatly from enhancing its product portfolio and proliferating those products across its installed base. However, for any small software company to survive it must be strong - and that means it must be profitable. We would prefer ATG focus on becoming profitable by aligning costs with realized revenue and investing in additional operating costs only as the revenue demands it. We believe that profitable operations would improve customers' attitudes towards ATG, bolster the stock price and put ATG in control of its future. -------------------------------------------------------------------------------- MITCHELL-WRIGHT TECHNOLOGY GROUP, LLC, MITCHELL-WRIGHT, LLC, SSH PARTNERS I, LP, ARCADIA PARTNERS, L.P., ARCADIA CAPITAL MANAGEMENT, LLC, JAMES DENNEDY AND RICHARD ROFE ARE PARTICIPANTS IN A SOLICITATION OF PROXIES FROM THE SHAREHOLDERS OF ART TECHNOLOGY GROUP, INC.
