ISS And Glass Lewis Recommend Quovadx Stockholders Vote ``FOR'' Proposed $3.20 Per Share Cash Merger with Quartzite Holdings

Quovadx, Inc. (NASDAQ: QVDX), a global software and vertical solutions company, today announced that Institutional Shareholder Services (ISS) and Glass, Lewis & Co. (Glass Lewis), two leading independent proxy advisory firms, recommend that Quovadx stockholders vote "FOR" the proposed merger of Quovadx, Inc. and a subsidiary of Quartzite Holdings, Inc. (a wholly owned subsidiary of Battery Ventures VII, L.P.) Under terms of the agreement, Quovadx stockholders will be entitled to receive $3.20 per share in cash for each share of Quovadx stock owned. The stockholder vote on the transaction will take place at a special meeting of Quovadx stockholders to be held Wednesday, July 18, 2007 at 9:00 A.M., local time, at Harlequin Plaza, North Building First Floor Conference Room, 7600 East Orchard Road, Greenwood Village, Colorado 80111. ISS and Glass Lewis provide voting advice to hundreds of institutional investors, mutual and pension funds and other fiduciaries. In recommending that Quovadx stockholders vote "FOR" the proposed merger, ISS stated(a): "The one-day announcement premium and the 60-day announcement premium are 25.5 percent and 20.1 percent, respectively. Based on our review of the terms of the transaction and the factors described [in our report], in particular the merger premium, we believe that the merger agreement warrants shareholder support.” Glass Lewis concluded that: "Overall, we believe the proposed transaction to be fair to shareholders. Given the thoroughness of the sales process, absence of significant conflicts of interest, and unanimous support of the board, we believe the transaction is in the interest of shareholders. Furthermore, we note that the proposed consideration approaches a three year high value for shareholders. Accordingly, we recommend that shareholders vote FOR the proposal." (a)Permission to use quotes neither sought nor received. "We are pleased that both ISS and Glass Lewis agree with the Quovadx board of directors’ recommendation that stockholders vote in favor of these proposals,” said Harvey A. Wagner, Quovadx chief executive officer. "We believe that the $3.20 per share cash merger, which was carefully considered and unanimously approved by the board of directors, provides an attractive transaction for our stockholders.” Both ISS and Glass Lewis recommend that Quovadx stockholders vote to approve three separate proposals, including: A vote FOR the proposed agreement and plan of merger by and among Quovadx, Inc.; Quartzite Holdings, Inc., a wholly owned subsidiary of Battery Ventures VII, L.P.; and Quartzite Acquisition Sub, Inc., a wholly owned subsidiary of Quartzite Holdings; A vote FOR a pre-closing restructuring of Quovadx, under which Quovadx will effect the sale of certain assets used in the operation of its Integration Solutions division to ISD Acquisition Corp, a wholly owned subsidiary of Battery Ventures, immediately prior to the closing of the merger; and A vote FOR a proposal to approve any adjournments or postponements of the special meeting of Quovadx stockholders, if necessary or appropriate, to permit further solicitation of proxies if there are insufficient votes today to approve and adopt the merger agreement.
