EXHIBIT 99.(d)(2) STOCKHOLDER AGREEMENT STOCKHOLDER AGREEMENT (this "Agreement") dated as of May 4, 2000 among ShopKo Stores, Inc., a Wisconsin corporation, SKO Holdings, Inc. a Delaware corporation and a wholly owned subsidiary of ShopKo Stores, Inc. (collectively, "Holder"), Merck & Co., Inc., a New Jersey corporation ("Parent"), and PV Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"). Parent, Merger Sub and ProVantage Health Services, Inc., a Delaware corporation (the "Company"), propose to enter into a Merger Agreement (the "Merger Agreement") on the date of this Agreement providing for the making of a tender offer by Merger Sub (the "Offer") for shares of Common Stock, par value $0.01 per share, of the Company (the "Company Common Stock"), at a purchase price of $12.25 per share, and a subsequent merger (the "Merger") between the Company and the Merger Sub. Holder owns the number of shares of Company Common Stock (the "Shares") or options to purchase Company Common Stock (the "Stock Options" and collectively, with the Shares, the "Optioned Securities"), or has the right to vote the number of Shares or other securities (the "Voting Securities"), listed on Schedule 1. Parent and the Merger Sub have required, as a condition to entering into the Merger Agreement, that the Holder enter into this Agreement. The Holder believes that it is in the best interest of the Company and its stockholders to induce Parent and the Merger Sub to enter into the Merger Agreement and, therefore, the Holder is willing to enter into this Agreement. Accordingly, in consideration of the mutual covenants and agreements set forth herein and in consideration of $1.00 and such other valuable consideration the receipt of which is hereby acknowledged, the parties hereto agree as follows: 1. The Option. Subject to the terms of this Agreement, Holder hereby ---------- grants the Merger Sub an irrevocable option (the "Option") to purchase all, and not less than all, of the Optioned Securities of Holder at the price of $12.25 per share (or such higher price as may be paid pursuant to the Offer), payable in cash, without interest. The obligation to pay the exercise price for the Option shall be a joint and several obligation of Parent and Merger Sub. 2. Exercise of the Option; Term. ---------------------------- (a) On the terms and subject to the conditions of this Agreement, the Merger Sub may exercise the Option at any time after the date on which all waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), applicable to the exercise of the Option have expired or been terminated by written notice to Holder specifying a date and time for the closing not later than thirty (30) business days from the date of such notice (which date and time may be two business days after the delivery of such notice) and after the Offer has expired or been terminated; provided, however, that the Option may not be exercised after it has expired in accordance with the terms hereof. (b) The Option shall expire on the earliest of: (1) the purchase of the Optioned Securities by the Merger Sub pursuant to the Offer; (2) the Effective Time (as defined in the Merger Agreement); (3) the termination of the Merger Agreement: (A) pursuant to the mutual consent of the Company and Parent pursuant to Section 7.01(a) of the Merger Agreement; (B) pursuant to Section 7.01(b) of the Merger Agreement (regarding failure of the Offer to be consummated by December 31, 2000); (C) pursuant to Section 7.01(c) of the Merger Agreement (regarding illegality or prohibition of the Offer or the Merger); (D) pursuant to Section 7.01(d) of the Merger Agreement (regarding a Superior Proposal); (E) pursuant to Section 7.01(e) of the Merger Agreement (regarding termination by Parent on the happening of certain events); or (4) thirty (30) days after termination or expiration of the Offer (such earliest date being referred to in this Agreement as the "Expiration Date"). (c) If the Company receives an Acquisition Proposal (as defined in the Merger Agreement) which the Company in good faith, after compliance with Section 5.02 of the Merger Agreement, believes is a Superior Proposal (as defined in the Merger Agreement) and gives written notice to Parent of such Superior Proposal in compliance with Section 5.02 of the Merger Agreement, Parent and Merger Sub will not exercise the Option (if it is then exercisable) for a period commencing on the date of such written notice and ending on the first to occur of: (1) one business day after the Company can properly terminate the Merger Agreement pursuant to Section 7.01(d), (2) written notice to Parent and Merger Sub from the Company that such Superior Proposal is not being pursued, which notice shall be provided by the Company to Parent and Merger Sub in writing promptly upon any such determination, and (3) the date on which the Company -2- receives a written and binding offer that is at least as favorable, from a financial point of view, to the stockholders of the Company as the Superior Proposal (such period is referred to herein as the "Review Period"). (d) Merger Sub and Parent agree that if Merger Sub exercises the Option and the Merger Agreement remains in full force and effect (i) the Shares purchased by Merger Sub pursuant to the Option shall be treated for purposes of the Merger Agreement and the Offer as if such Shares were purchased by Merger Sub in the Offer and (ii) Parent and Merger Sub will ensure that the transactions contemplated by the Merger Agreement (including the Offer and the Merger) are consummated. Merger Sub and Parent further agree that if Merger Sub exercises the Option and the Merger Agreement is not in full force and effect (i) Parent and Merger Sub will cause the Merger Agreement to again become in full force and effect (or to cause a merger agreement containing the same economic terms to become in force and effect) and (ii) Parent and Merger Sub will ensure that the transactions contemplated by the Merger Agreement (or any replacement merger agreement), including the Offer and the Merger, are fully consummated. 3. Closing. At the closing: ------- (a) against delivery of the Optioned Securities, free and clear of all liens, claims, charges and encumbrances of any kind or nature whatsoever, Parent shall cause the Merger Sub to make payment to Holder of the aggregate price for Holder's Optioned Securities by wire transfer of immediately available funds; and (b) Holder shall deliver to the Merger Sub a duly executed certificate or certificates representing the number of Optioned Securities purchased from Holder, together with transfer powers endorsed in blank relating to such certificates and, if requested by the Merger Sub, an irrevocable proxy duly executed by Holder, authorizing such persons as the Merger Sub shall designate to act for Holder as his lawful agents, attorneys and proxies, with full power of substitution, to vote in such manner as each such agent, attorney and proxy or his substitute shall in his sole discretion deem proper, and otherwise act with respect to the Optioned Securities at any meeting (whether annual or special and whether or not an adjourned meeting) of the Company's stockholders or otherwise, and revoking any prior proxies granted by Holder with respect to the Holder's Optioned Securities. Notwithstanding any provision of this Agreement to the contrary, the Holder shall validly tender its Shares pursuant to the Offer and shall not withdraw such Shares prior to the expiration of the Offer, and its obligation to sell any Optioned Securities shall be satisfied, solely with respect to the Shares so tendered, upon the purchase of such Shares by the Merger Sub pursuant to the Offer. -3- 4. Covenants of the Holder. ----------------------- (a) During the period from the date of this Agreement until the Expiration Date, except in accordance with the provisions of this Agreement, Holder agrees that it will not: (i) sell, sell short, transfer, pledge, hypothecate, assign or otherwise dispose of, or enter into any contract, option, hedging arrangement or other arrangement or understanding with respect to the sale, transfer, pledge, hypothecation, assignment or other disposition of, any Optioned Securities or Voting Securities; (ii) deposit any Optioned Securities or Voting Securities into a voting trust, or grant any proxies or enter into a voting agreement with respect to any Optioned Securities or Voting Securities; or (iii) except for actions permitted by Section 5.02 of the Merger Agreement, initiate, solicit or knowingly encourage, directly or indirectly, any inquiries or the making or implementation of any proposal that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal (as defined in the Merger Agreement) or enter into discussions or negotiate with any person or entity in furtherance of such inquiries or to obtain a Acquisition Proposal, or agree to or endorse any Acquisition Proposal. (b) Any additional shares of Company Common Stock, warrants, options or other securities or rights exercisable for, exchangeable for or convertible into shares of Company Common Stock (collectively, "Equity Securities") acquired by Holder will become subject to this Agreement and shall, for all purposes of this Agreement, be considered Optioned Securities or Voting Securities, as the case may be. (c) Holder agrees not to engage in any action or omit to take any action which would have the effect of preventing or disabling Holder from delivering its Optioned Securities to the Merger Sub or otherwise performing its obligations under this Agreement. To the extent that any Optioned Securities (other than Company Common Stock) may not be assigned by Holder to the Merger Sub without exercising, exchanging or converting such Optioned Securities for or into Company Common Stock, Holder agrees to exercise, exchange or convert such Optioned Securities for or into Company Common Stock prior to the closing of the purchase of such Optioned Securities upon exercise of the Option. -4- 5.

Voting of Equity Securities. Holder hereby agrees that, from the date --------------------------- hereof until the Expiration Date, at any meeting of the stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, it shall (a) vote all Voting Securities of Holder in favor of the Merger; (b) not vote any Voting Securities in favor of any action or agreement which would result in a breach in any material respect of any covenant, representation or warranty or any other obligation of the Company under the Merger Agreement; and (c) vote all Voting Securities of Holder against any action or agreement which would impede, interfere with or attempt to discourage the Offer or the Merger, including, but not limited to: (i) any Acquisition Proposal (other than the Offer and the Merger) involving the Company or any of its subsidiaries; (ii) any change in the management or board of directors of the Company, except as otherwise agreed to in writing by the Merger Sub; (iii) any material change in the present capitalization or dividend policy of the Company; or (iv) any other material change in the Company's corporate structure or business.
