AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of August 13, 2003, among CareScience, Inc., a Pennsylvania corporation (the "Company"), Quovadx, Inc., a Delaware corporation ("Parent"), and Carlton Acquisition Corp., a Pennsylvania corporation and a wholly-owned subsidiary of Parent ("Merger Subsidiary").

WHEREAS, the Board of Directors of the Company (the "Company Board") has unanimously (i) determined that this Agreement and the transactions contemplated hereby, including the Offer (as defined herein) and the Merger (as defined herein), are fair to and in the best interests of the shareholders of the Company, (ii) determined that the consideration to be paid in the Offer and the Merger is fair to and in the best interests of the shareholders of the Company, (iii) approved this Agreement and the transactions contemplated hereby, including the Offer and the Merger, and (iv) resolved to recommend that the shareholders of the Company accept the Offer and tender their Shares (as defined below) to Merger Subsidiary and, if necessary, approve and adopt this Agreement, the Merger and the other transactions contemplated hereby;

WHEREAS, the respective Boards of Directors of Parent and Merger Subsidiary have approved this Agreement and the transactions contemplated hereby, including the Offer and the Merger;

WHEREAS, in furtherance thereof, it is proposed that Merger Subsidiary shall, as promptly as practicable, commence an exchange offer (the "Offer") to acquire all of the outstanding shares of common stock, no par value per share, of the Company (the "Shares"), at a price for each Share of (i) $1.40 in cash (such price, or such higher price per share in cash that may be made pursuant to the Offer, is referred to as the "Cash Portion"), and (ii) 0.1818 of a share of Common Stock, par value $0.01 per share (the "Parent Common Stock"), of Parent (such fraction of a share, or such higher fraction of a share that may be made pursuant to the Offer, is referred to as the "Stock Portion") (subject to adjustment as set forth in Section 2.2 hereof) (such Cash Portion and Stock Portion being hereinafter referred to as the "Offer Price"), in accordance with the terms and subject to the conditions provided herein;

WHEREAS, also in furtherance thereof, it is proposed that, following the consummation of the Offer, Merger Subsidiary will merge with and into the Company (the "Merger") and that the Shares not tendered and accepted pursuant to the Offer will thereupon be converted into the right to receive both cash and a fraction of a share of Parent Common Stock in the amounts set forth in Section 2.1 hereof;

WHEREAS, concurrently with the execution of this Agreement, the officers and directors of the Company listed on Schedule A, in their capacity as shareholders, are entering into Affiliate Agreements in substantially the form attached hereto as Exhibit A;

WHEREAS, Parent, Merger Subsidiary and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe various conditions to consummation of the Merger.

NOW, THEREFORE, in consideration of the foregoing and the mutual premises, representations, warranties, covenants and agreements herein contained, the parties hereto, intending to be legally bound, hereby agree as follows:

ARTICLE I

THE OFFER AND THE MERGER

SECTION 1.1 The Offer.

(a) Provided that (i) this Agreement shall not have been terminated in accordance with Section 9.1 and (ii) none of the events set forth in Annex A hereto that would entitle Parent and Merger Subsidiary to fail to consummate the Offer shall have occurred and be continuing (and shall not have been waived by Parent), as promptly as practicable, Merger Subsidiary shall (and Parent shall

cause Merger Subsidiary to) commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), the Offer for any and all of the Shares, at the Offer Price. The obligation of Merger Subsidiary to accept for payment and to pay for any Shares tendered (and the obligation of Parent to cause Merger Subsidiary to accept for payment and to pay for any Shares tendered) shall be subject only to (i) the condition that at least 80% of the outstanding Shares be validly tendered and not withdrawn (the "Minimum Condition"), and (ii) the other conditions set forth in Annex A. Merger Subsidiary expressly reserves the right to increase the Offer Price or to make any other changes in the terms and conditions of the Offer; provided, however, that unless previously approved by the Company in writing, no change may be made that (i) decreases the Offer Price or the Cash Portion or the Stock Portion thereof, (ii) changes the form or combination of consideration to be paid in the Offer, (iii) reduces the number of Shares to be purchased in the Offer, (iv) amends the conditions set forth in Annex A to broaden the scope of such conditions, add any additional conditions, or otherwise adversely affect the holders of Shares, (v) extends the Offer except as provided in Section 1.1(b), or (vi) amends or waives the Minimum Condition. It is agreed that the conditions set forth in Annex A are for the sole benefit of Parent and Merger Subsidiary and may be waived by Parent and Merger Subsidiary, in whole or in part at any time and from time to time, in their sole discretion, other than the Minimum Condition, as to which prior written Company approval is required. The failure by Parent and Merger Subsidiary at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right, and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time. The Company agrees that no Shares held by the Company or its Subsidiary will be tendered in the Offer.

(b) Subject to the terms and conditions thereof, the Offer shall expire at midnight, New York City time, on the date that is twenty (20) business days after the date the Offer is commenced; provided, however, that without the consent of the Company Board (the "Company Board"), Merger Subsidiary may (i) from time to time extend the Offer, if at the scheduled expiration date of the Offer any of the conditions to the Offer shall not have been satisfied or waived, until such time as such conditions are satisfied or waived, but not beyond the termination of this Agreement pursuant to Article IX; (ii) extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the "SEC") or the staff thereof applicable to the Offer; or (iii) include a subsequent offering period (as such term is defined in Rule 14d-1 under the Exchange Act) to the Offer for a period up to twenty (20) business days. Subject to the terms and conditions of the Offer and this Agreement, Merger Subsidiary shall (and Parent shall cause Merger Subsidiary to) accept for payment, and pay for, all Shares validly tendered and not withdrawn pursuant to the Offer that Merger Subsidiary becomes obligated to accept for payment and pay for pursuant to the Offer, as promptly as practicable after the expiration of the Offer. No fraction of a share of Parent Common Stock will be issued in connection with the payment of the Stock Portion upon consummation of the Offer, but in lieu thereof each tendering shareholder who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that otherwise would be received by such holder) in the Offer shall receive from Parent an amount of cash (rounded to the nearest whole cent), without interest, equal to the product obtained by multiplying such fraction by the closing price of one (1) share of Parent Common Stock on the first date Merger Subsidiary accepts Shares for exchange in the Offer, as reported on the Nasdaq National Market ("Nasdaq"). With respect to any such Shares the Cash Portion shall be net to the seller thereof in cash, subject to reduction only for any applicable federal back-up withholding or stock transfer taxes payable by such seller.

(c) As soon as practicable after the date of this Agreement, Parent shall prepare and file with the SEC a registration statement on Form S-4 to register the offer and sale of Parent Common Stock pursuant to the Offer (the "Registration Statement"). The Registration Statement will include a preliminary prospectus containing the information required under Rule 14d-4(b) promulgated under the Exchange Act (the "Preliminary Prospectus"). As soon as practicable on the date the Offer is

commenced, Parent and Merger Subsidiary shall file with the SEC a Tender Offer Statement on Schedule TO (together with all amendments and supplements thereto, and including all exhibits thereto, the "Schedule TO") with respect to the Offer and shall cause the Offer Documents to be disseminated to holders of Shares. The Schedule TO shall contain as an exhibit or incorporate by reference the Preliminary Prospectus (or portions thereof) and forms of the related letter of transmittal and summary advertisement, if any. Parent and Merger Subsidiary agree that they shall cause the Schedule TO, the Preliminary Prospectus and all amendments or supplements thereto (which together constitute the "Offer Documents") to comply in all material respects with the Exchange Act and the rules and regulations thereunder and other applicable Laws (as defined in Section 4.1(c)). Parent and Merger Subsidiary further agree that the Offer Documents, on the date first published, sent or given to the Company's shareholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation or warranty is made by Parent or Merger Subsidiary with respect to information supplied by the Company or any of its shareholders in writing specifically for inclusion or incorporation by reference in the Offer Documents. The Company agrees that the information provided by the Company in writing specifically for inclusion or incorporation by reference in the Offer Documents shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of Parent, Merger Subsidiary and the Company agrees promptly to correct any information provided by it for use in the Registration Statement or the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and Parent and Merger Subsidiary further agree to take all steps necessary to cause the Schedule TO as so corrected to be filed with the SEC and the other Offer Documents as so corrected to be disseminated to the Company's shareholders, in each case as and to the extent required by applicable federal securities laws. The Company and its counsel shall be given reasonable opportunity to review and comment on the Schedule TO, the Registration Statement and the Offer Documents prior to the filing thereof with the SEC. Parent and Merger Subsidiary agree to provide in writing to the Company and its counsel with any comments Parent, Merger Subsidiary or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after receipt of such comments and shall provide Company and its counsel with a reasonable opportunity to participate in the response of Parent or Merger Subsidiary to such comments. Parent shall use all reasonable efforts to have the S-4 declared effective under the Securities Act as promptly as practicable after its filing and to maintain such effectiveness for so long as shall be required for the issuance of Parent Common Stock pursuant to the Offer. Following the time the S-4 is declared effective, Parent shall file the final prospectus included therein under Rule 424(b) promulgated pursuant to the Securities Act.

SECTION 1.2 Company Actions With Respect to the Offer.

(a) The Company hereby approves of and consents to the Offer and represents that the Company Board, at a meeting duly called and held, subject to the terms and conditions set forth herein, has unanimously (i) determined that this Agreement and the transactions contemplated hereby, including the Offer and the Merger, taken together, are at a price and on terms that are advisable and fair to and in the best interests of the Company and its shareholders; (ii) approved this Agreement and the transactions contemplated hereby, including the Offer and the Merger, in all respects; and (iii) resolved to recommend that the shareholders of the Company accept the Offer, tender their Shares thereunder to Merger Subsidiary and approve and adopt this Agreement and the Merger, provided that such recommendation may be withdrawn, amended or modified in accordance with Section 5.4 hereof. To the extent that such recommendation is not withheld, withdrawn, amended or modified in accordance with Section 5.4 hereof, the Company consents to the inclusion of such recommendation and approval in the Offer Documents. In addition, ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Company, L.L.C. has delivered to the Company Board its opinion referred to in Section 4.1(t). The Company has been advised by each

of its directors and executive officers that they each intend to tender all Shares beneficially owned by them to Merger Subsidiary pursuant to the Offer.

(b) The Company shall file with the SEC, concurrently with the filing of the Schedule TO, a Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments and supplements thereto, and including all exhibits thereto, the "Schedule 14D-9") containing the recommendations and opinion described in Section 1.2(a) (unless withdrawn in accordance with Section 5.4 hereof, or as modified or amended in accordance with Section 5.4 hereof) and shall cause the Schedule 14D-9 to be mailed to the shareholders of the Company, together with the Offer Documents, promptly after the commencement of the Offer; provided, that the Company Board may withhold, withdraw, amend or modify its recommendation and recommend a Superior Proposal in accordance with the terms of Section 5.4. The Company agrees that it shall cause the Schedule 14D-9 to comply in all material respects with the Exchange Act and the rules and regulations thereunder and other applicable Laws. The Company further agrees that the Schedule 14D-9, on the date first published, sent or given to the Company's shareholders, shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation or warranty is made by the Company with respect to information supplied by Parent or Merger Subsidiary in writing specifically for inclusion or incorporation by reference in the Schedule 14D-9. Parent and Merger Subsidiary agree that the information provided by them specifically in writing for inclusion or incorporation by reference in the Schedule 14D-9 shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the Company, Parent and Merger Subsidiary agrees promptly to correct any information provided by it for use in the Schedule 14D-9 or the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and the Company further agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and be disseminated to the Company's shareholders, in each case as and to the extent required by applicable federal securities laws. Parent and its counsel shall be given reasonable opportunity to review and comment on the Schedule 14D-9 prior to the filing thereof with the SEC. The Company agrees to provide in writing to Parent and its counsel any comments the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments and shall provide Parent and Merger Subsidiary and their counsel with a reasonable opportunity to participate in the response of Company to such comments.

(c) In connection with the Offer, the Company shall, or shall cause its transfer agent, promptly following a request by Parent, to furnish Parent with such information, including updated lists of the shareholders of the Company, mailing labels and updated lists of security positions, and such assistance as Parent or its agents may reasonably request in communicating the Offer to the record and beneficial holders of Shares. Subject to any applicable Laws, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Merger, Parent and Merger Subsidiary and their agents shall hold in confidence the information contained in any such labels, listings and files, will use such information only in connection with the Offer and the Merger and, if this Agreement shall be terminated, will deliver, and will use their reasonable efforts to cause their agents to deliver, to the Company all copies and any extracts or summaries from such information then in their possession or control.

(d) Solely in connection with the tender and purchase of Shares pursuant to the Offer and the consummation of the Merger, the Company hereby waives any and all rights of first refusal it may have with respect to Shares owned by, or issuable to, any person, other than rights to repurchase unvested shares, if any, that may be held by persons pursuant to the grant of restricted stock purchase rights or following exercise of employee stock options.

SECTION 1.3 Boards of Directors and Committees.

(a) Effective upon the acceptance for payment by Merger Subsidiary of Shares pursuant to the Offer (the "Appointment Date") and from time to time thereafter, if the Minimum Condition has been met, and subject to the second to last sentence of this Section 1.3(a), Parent shall be entitled to designate up to such number of directors, rounded up to the next whole number, on the Company Board as will give Parent representation on the Company Board equal to the product of the number of directors on the Company Board (giving effect to any increase in the number of directors pursuant to this Section 1.3) and the percentage that such number of Shares so purchased bears to the total number of outstanding Shares, and the Company shall use its best efforts to, upon request by Parent, promptly, at the Company's election, either increase the size of the Company Board or secure the resignation of such number of directors as is necessary to enable Parent's designees to be elected to the Company Board and to cause Parent's designees to be so elected. At such times, and subject to the second to last sentence of this Section 1.3(a), the Company shall use its best efforts to cause the individuals designated by Parent to constitute the same percentage as is on the Company Board of (i) each committee of the Company Board, (ii) each board of directors of each subsidiary of the Company (subject to applicable Laws and except to the extent described in Schedule 1.3(a)) and (iii) each committee of each such board of directors. Notwithstanding the foregoing, the Company shall use its commercially reasonable efforts to ensure that two of the members of the Company Board as of the date hereof (the "Continuing Directors") shall remain members of such Board until the Effective Time. If a Continuing Director resigns from the Company Board, Parent, Merger Subsidiary and the Company shall permit the remaining Continuing Director or Directors to appoint the resigning Director's successor who shall be deemed to be a Continuing Director.

(b) The Company's obligation to appoint designees to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly take all action required pursuant to such Section and Rule in order to fulfill its obligations under this Section 1.3 and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors as is required under such Section and Rule in order to fulfill its obligations under this Section 1.3. Parent shall promptly supply to the Company in writing and be solely responsible for any information with respect to itself and its nominees, officers, directors and affiliates required by such Section and Rule.

(c) Following the Appointment Date, if there shall be any Continuing Directors, any amendment of this Agreement, any termination of this Agreement by the Company, any extension by the Company of the time for the performance of any of the obligations or other acts of Parent or Merger Subsidiary or any waiver of any of the Company's rights hereunder or any other determination with respect to any action to be taken or not to be taken by the Company relating to this Agreement, will require the concurrence of a majority of such Continuing Directors.

SECTION 1.4 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Pennsylvania Business Corporation Law of 1988 (the "PBCL"), Merger Subsidiary shall be merged with and into the Company at the Effective Time (as defined herein). At the Effective Time, the separate corporate existence of Merger Subsidiary shall cease, and the Company (i) shall continue as the surviving corporation as a direct wholly-owned subsidiary of Parent (Merger Subsidiary and the Company are sometimes hereinafter referred to as "Constituent Corporations" and, as the context requires, the Company, after giving effect to the Merger, is sometimes hereinafter referred to as the "Surviving Corporation"), (ii) shall succeed to and assume all the rights and obligations of Merger Subsidiary in accordance with the PBCL, (iii) shall continue under the name "CareScience, Inc." and (iv) shall be governed by the laws of the Commonwealth of Pennsylvania.

SECTION 1.5 Merger Without Shareholder Vote. In the event that Parent, Merger Subsidiary or any other Subsidiary of Parent, shall acquire at least eighty percent (80%) of the then-outstanding Shares pursuant to the Offer or otherwise, each of the parties hereto shall take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after such acquisition, without a meeting of shareholders of the Company, in accordance with Section 1924(b) of the PBCL.

SECTION 1.6 Closing. The closing of the Merger (the "Closing") shall take place at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP, Two ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ as soon as practicable, but in any case on or prior to the third business day after all of the conditions set forth in Article VIII hereof shall have been fulfilled or waived in accordance with this Agreement. At the time of the Closing, the Company and Merger Subsidiary will file a articles of merger with the Department of State of the Commonwealth of Pennsylvania and make all other filings or recordings required by the PBCL in connection with the Merger.

SECTION 1.7 Effective Time of the Merger. The Merger shall, subject to the PBCL, become effective as of such time as the articles of merger are duly filed with the Department of State of the Commonwealth of Pennsylvania or at such later time as is specified in the articles of merger (the "Effective Time").

SECTION 1.8 Effects of the Merger. From and after the Effective Time, the Surviving Corporation shall possess all the rights, privileges, powers and franchises and be subject to all of the restrictions, disabilities and duties of the Company and Merger Subsidiary, all as provided under the PBCL.

SECTION 1.9 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Merger Subsidiary, the officers and directors of the Company and Merger Subsidiary will take all such lawful and necessary action.

ARTICLE II

EFFECT OF THE MERGER ON THE CAPITAL
STOCK OF THE CONSTITUENT CORPORATIONS

SECTION 2.1 Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any Shares or any shares of capital stock of Merger Subsidiary:

(a) each Share owned by the Company or owned by Parent, Merger Subsidiary or any subsidiary of any of the Company, Parent or Merger Subsidiary immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto;

(b) each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation; and

(c) each Share outstanding immediately prior to the Effective Time shall, except as otherwise provided in Section 2.1(a) or as provided in Section 2.3 with respect to dissenting shares, be converted into the right to receive (x) the Cash Portion in cash per Share, without any interest thereon and (y) a fraction of a share of Parent Common Stock equal to the Stock Portion (subject to adjustment as set forth in Section 2.2(h) hereof) (the Cash Portion and the Stock Portion, and cash in lieu of fractional shares as specified below, are collectively referred to as the "Merger Consideration") upon surrender of the certificate representing such share of Company Common Stock in the manner provided in Section 2.2.

SECTION 2.2 Surrender and Payment. (a) Prior to the Effective Time, Parent shall appoint a bank or trust company (the "Exchange Agent") for the purpose of exchanging certificates representing Shares for the Merger Consideration. Parent will, or will cause Merger Subsidiary to, make available to the Exchange Agent, as needed, the Merger Consideration to be paid in respect of the Shares (the "Exchange Fund"). For purposes of determining the Merger Consideration to be made available, Parent shall assume that no holder of Shares will perfect his right to demand cash payment of the fair market value of his Shares pursuant to Chapter 15 of the PBCL. Promptly after the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of Shares at the Effective Time a letter of transmittal for use in such exchange (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the certificates representing Shares to the Exchange Agent). The Exchange Agent shall, pursuant to irrevocable instructions, make the payments provided in this Section 2.2. The Exchange Fund shall not be used for any other purpose, except as provided in this Agreement.

(b) Each holder of Shares that have been converted into a right to receive the Merger Consideration, upon surrender to the Exchange Agent of a certificate or certificates representing such Shares, together with a properly completed letter of transmittal covering such Shares and other customary documentation, will be entitled to receive the Merger Consideration payable in respect of such Shares. As of the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate previously representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, without interest, upon surrender of the certificates representing such Shares, as contemplated hereby.

(c) If any portion of the Merger Consideration is to be paid to a person other than the registered holder of the Shares represented by the certificate or certificates surrendered in exchange therefor, it shall be a condition to such payment that the certificate or certificates so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a person other than the registered holder of such Shares or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable. For purposes of this Agreement, "person" means an individual, a corporation, a partnership, a limited liability company, an association, a trust or any other entity or organization, including a government or political subdivision or any agency or instrumentality thereof.

(d) After the Effective Time, there shall be no further registration of transfers of Shares. If, after the Effective Time, certificates representing Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article II.

(e) Required Withholding. Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of the Shares such amounts as may be required to be deducted or withheld therefrom under the U.S. Internal Revenue Code or under any provision of state, local or foreign tax law or under any other applicable legal requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

(f) Lost, Stolen or Destroyed Certificates. In the event that any certificates representing Shares ("Certificates") shall have been lost, stolen or destroyed, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable with respect thereto; provided, however, that Parent may, in

its discretion and as a condition precedent to the payment of such Merger Consideration, require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such reasonable and customary amount as it may direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Exchange Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

(g) Any portion of the Exchange Fund made available to the Exchange Agent pursuant to this Agreement that remains unclaimed by the holders of Shares six months after the Effective Time shall be returned to Parent, upon Parent's demand, and any such holder who has not exchanged his Shares for the Merger Consideration in accordance with this Section 2.2 prior to that time shall thereafter look only to Parent for payment of the Merger Consideration in respect of his Shares. Notwithstanding the foregoing, Parent shall not be liable to any holder of Shares for any amount paid to a public official pursuant to and in accordance with the requirements of applicable abandoned property, escheat or similar laws.

(h) In the event that Parent changes (or establishes a record date for changing) the number of, or provides for the exchange of, shares of Parent Common Stock issued and outstanding prior to the Appointment Date or the Effective Time, as a result of a stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction with respect to the outstanding Parent Common Stock, and the record date therefore shall be prior to the Appointment Date or the Effective Date, the Stock Portion per Share of the Offer Price or the Merger Consideration, respectively, shall be adjusted accordingly to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to such stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction. In the event that the Company changes (or establishes a record date for changing) the number of, or provides for the exchange of, the Shares issued and outstanding prior to the Appointment Date or the Effective Time, as a result of a stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction with respect to the Shares, and the record date therefore shall be prior to the Appointment Date or the Effective Date, the Offer Price or the Merger Consideration per Share, respectively, shall be adjusted accordingly to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to such stock split, stock dividend, recapitalization, reclassification, reorganization or similar transaction.

(i) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 2.2(a) to pay for Shares for which the right to a determination of fair market value, as contemplated by Section 2.3, have been perfected shall be returned to Parent upon Parent's demand.

(j) Fractional Shares. No fraction of a share of Parent Common Stock will be issued in connection with the payment of the Stock Portion of the Merger Consideration, but in lieu thereof each holder of a Certificate who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that otherwise would be received by such holder) in the Merger shall receive from Parent an amount of cash (rounded to the nearest whole cent), without interest, equal to the product obtained by multiplying such fraction by the closing price of one (1) share of Parent Common Stock on the Effective Time, as reported on the Nasdaq.

SECTION 2.3 Dissenting Shares. Notwithstanding Section 2.1, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to and has demanded cash payment of the fair value for such Shares in accordance with Subchapter D of Chapter 15 or Subchapter E of Chapter 25 of the PBCL (the "Dissenting Shares") shall not be converted into the right to receive the Merger Consideration as provided in Section 2.1 of this Agreement, unless and until such holder fails to perfect or withdraws or otherwise loses his right to a determination of the fair value of the shares and payment under Subchapter D of Chapter 15 of the PBCL or Subchapter E of Chapter 25, as applicable. If, after the Effective Time, any such holder fails to perfect or withdraws or loses his right to a determination of the fair value of the Shares under the PBCL, such Dissenting Shares shall

The Company will provide any notices required to be provided under the 1995 Plan and the 1998 Plan and will obtain any consents necessary to effectuate the foregoing cash-out of Company Options for those Holders who so agree to the cash-out.

SECTION 5.2 Affiliate Agreements. Promptly following the date hereof, the Company will obtain the signature of each the officers and directors of the Company listed on Schedule A hereto of an Affiliate Agreement in substantially the form attached as Exhibit A hereto.

SECTION 5.3 Access to Information. From the date hereof until the Effective Time, the Company will give Parent, its counsel, financial advisors, auditors and other authorized representatives full access (during normal business hours and upon reasonable notice) to the offices, properties, officers, employees, accountants, auditors, counsel and other representatives, books and records of the Company and its Subsidiary, will furnish to Parent, its counsel, financial advisors, auditors and other authorized representatives such financial, operating and property related data and other information as such persons may reasonably request, and will instruct the Company's and its Subsidiary's employees, counsel and financial advisors to cooperate with Parent in its investigation of the business of the Company and its Subsidiary.

SECTION 5.4 No Solicitation.

(a) The Company agrees that neither the Company nor its Subsidiary nor any of the respective officers, directors, employees, agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by the Company or its Subsidiary) of the Company or its Subsidiary shall, (i) initiate, continue, solicit or encourage, directly or indirectly, any inquiries or the making of any proposal or offer (including, without limitation, any proposal or offer to shareholders of the Company) with respect to a merger, consolidation or similar transaction involving, or any purchase of all or any significant portion of the assets or any equity securities of, the Company or its Subsidiary (any such proposal or offer being hereinafter referred to as an "Acquisition Proposal"), or (ii) engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any person relating to an Acquisition Proposal, or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal or enter into any agreement or understanding with any other person or entity with the intent to effect any Acquisition Proposal. Notwithstanding the foregoing, prior to the Appointment Date the Company may, in the event that a third party that has made (and not withdrawn) a bona fide Acquisition Proposal that the Company Board reasonably concludes in good faith (after consultation with its financial advisor) constitutes, or is likely to lead to, a Superior Proposal, (i) engage or participate in discussions or negotiations with such third party and/or (ii) furnish to such third party nonpublic information relating to Company or its Subsidiary pursuant to a confidentiality agreement with terms no less favorable to Company than those contained in the Confidentiality Agreement; provided, that in each case (x) neither Company nor any representative of Company and its Subsidiary shall have violated any of the restrictions set forth in this Section 5.4, (y) the Company Board reasonably concludes in good faith, after consultation with its outside legal counsel, that in light of such Acquisition Proposal the failure to take such action would be reasonably expected to be a violation of the fiduciary obligations of the Company Board to the Company's shareholders, and (z) contemporaneously with furnishing any such information to such person or group, the Company furnishes such information to Parent (to the extent such information has not been previously furnished by Company to Parent). The Company will take all necessary steps to inform the individuals or entities referred to in the first sentence hereof of the obligations undertaken in this Section 5.4. The Company will notify Parent promptly, orally and in writing (including the names of any party making, the principal terms of, and any written materials provided in connection with, any such proposal, request or inquiry), if any such inquiries or proposals are received by, any such information is requested from, or any such negotiations or discussions are sought to be initiated or continued with the Company. Immediately following the execution of this Agreement, the Company will request each person which has heretofore executed a confidentiality agreement in connection with its consideration of acquiring the Company or any portion thereof to return all confidential information heretofore furnished to such person by or on behalf of the Company. The Company will keep Parent fully and promptly informed of the status and details (including amendments or proposed amendments) of, and will promptly provide copies of any written materials provided in connection with, any such request, proposal or inquiry.

For purposes of this Agreement, "Superior Proposal" means any bona fide Acquisition Proposal (1) to acquire, directly or indirectly, all of the Shares then outstanding, or all or substantially all of the assets of the Company, (2) that contains terms and conditions that the Board of Directors reasonably determines in good faith (after consultation with its financial advisor) to be more favorable from a financial point of view to the Company's shareholders than the Offer and the Merger, (3) that the Company Board reasonably determines in its good faith judgment (after consultation with its financial advisor and its legal counsel) to be reasonably capable of being completed (taking into account all legal, financial, regulatory and other aspects of the proposal and the person making the proposal), (4) that does not contain a "right of first refusal" or "right of first offer" with respect to any counter-proposal that Parent might make, and (5) that does not contain any "due diligence" condition and for which any financing upon which it is conditioned is committed.

(b) Except as set forth in this Section 5.4(b), the Company Board shall not make a change in its recommendation that the shareholders of the Company accept the offer, tender their Shares thereunder to Merger Subsidiary and adopt this Agreement and the Merger (a "Change in the Company Recommendation"). Notwithstanding the foregoing, if the Company Board determines in its reasonable good faith judgment prior to the Acceptance Date, after consultation with outside legal counsel, that the failure to make a Change in the Company Recommendation would be a violation of its fiduciary duties to the Company's shareholders, then the Company Board may make a Change in the Company Recommendation, but only (i) after providing written notice to Parent (a "Notice of Superior Proposal") advising Parent that the Company Board has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the person making such Superior Proposal and (ii) if Parent does not, within two business days of Parent's receipt of the Notice of Superior Proposal, make an offer that the Company Board determines in its good faith judgment (after consultation with its financial advisors) to be at least as favorable to the Company's shareholders as such Superior Proposal.

SECTION 5.5 Fair Price Structure. If any "fair price," "control share acquisition" or "moratorium" statute or other anti-takeover or similar statute or regulation or any state "blue sky" statute shall become applicable to the transactions contemplated hereby, the Company and the members of the Company Board shall use their best efforts to grant such approvals and take such actions as are necessary so that the transactions contemplated hereby and thereby may be consummated as promptly as practicable on the terms contemplated hereby and thereby and otherwise act to minimize the effects of such statute or regulation on the transactions contemplated hereby or thereby.

SECTION 5.6 Employee Plans. Except as set forth in Schedule 5.6, the Company and its ERISA Affiliates, as applicable, shall each terminate, effective as of the day immediately preceding the Effective Time, any and all group severance, separation or salary continuation plans, programs, or arrangements.
