Digital is the beneficial owner of all of the 18,090.45 shares of Series D Preferred Stock of the Company. 4 PROPOSAL NO. 1 APPROVAL TO CONVERT ALL OF THE OUTSTANDING SHARES OF SERIES D PREFERRED STOCK INTO COMMON STOCK At the Meeting, the stockholders of the Company will vote on a proposal to approve the conversion into shares of Common Stock all of the outstanding shares of the Company's Series D Preferred Stock, $.01 par value per share (the "Series D Preferred Stock"), that were issued to Digital in connection with the Company's acquisition of the AltaVista business from Compaq and Digital on August 18, 1999. On June 29, 1999, the Company entered into a Purchase and Contribution Agreement among itself, Compaq, Digital, a wholly owned subsidiary of Compaq, AltaVista Company, a wholly owned subsidiary of Digital ("AltaVista"), and Zoom Newco Inc., a wholly owned subsidiary of the Company ("Newco") (the "Purchase and Contribution Agreement"), which provided, among other things, that (1) Compaq and Digital contribute to Newco certain assets and liabilities constituting the AltaVista division of Digital, (2) Compaq and/or Digital receive 18,994,975 shares of the Company's Common Stock, 18,090.45 shares of the Company's Series D Preferred Stock and a three-year promissory note of the Company in the principal amount of $220,000,000, and (3) Compaq and/or Digital receive approximately 19% of the outstanding shares of the common stock of Newco and the Company will own the balance of the outstanding capital stock of Newco. Following the satisfaction of all closing conditions set forth in the Purchase and Contribution Agreement, the acquisition closed on August 18, 1999 (the "Closing"). As of the Closing, the 18,090.45 shares of the Series D Preferred Stock had an aggregate stated value of $180,000,000 and shall be converted, upon stockholder approval of the Conversion, into 1,809,045 shares of Common Stock. Compaq Computer Corporation ("Compaq") will abstain from voting any of its shares of Common Stock on the proposal to approve the Conversion. In connection with the sale of the AltaVista division to the Company, Compaq received 18,994,975 shares of the Company's Common Stock, representing approximately ___% of the outstanding shares of Common Stock. NASD rules require stockholder approval for the issuance of 20% or more of the Company's outstanding Common Stock. Because the conversion of the Series D Preferred Stock would result in Compaq receiving more than 20% of the Company's outstanding Common Stock, the Series D Preferred Stock may not be converted into shares of Common Stock without stockholder approval. If the stockholders approve the Conversion at the Meeting, the 18,090.45 shares of Series D Preferred Stock held by Compaq shall be converted into 1,809,045 shares of Common Stock, with the result that Compaq would hold shares of Common Stock representing, in the aggregate, approximately ___% of the outstanding shares of Common Stock. 5 Series D Preferred Stock of the Company The designations, amount, voting powers, preferences and rights of the Series D Preferred Stock are set forth in the Certificate of Designations of Series D Preferred Stock of the Company as filed with the Secretary of State of the State of Delaware. The following is a summary of the principal terms of the Series D Preferred Stock. Dividends and Distributions The holders of Series D Preferred Stock are entitled to receive cumulative dividends, payable quarterly from the date of issuance, at an annual return rate of 11.0% of the stated value per share ($9,950) for the first six months after issuance and 14.0% for the following six months. Thereafter, the annual return rate will increase by 50 basis points for each subsequent six month period up to a maximum annual return rate of 16.0%. Each holder of Series D Preferred Stock is also entitled to receive any dividend paid on the Common Stock through the date of the Conversion. However, no quarterly dividends will accrue or be payable for the first six months after issuance in the event that the Conversion occurs prior to the date six months after issuance. The dividends are payable at the option of the Company in cash, marketable securities or freely tradeable Common Stock, or any combination thereof. There are currently no outstanding dividends due to the holders of shares of Series D Preferred Stock. The Series D Preferred Stock ranks in preference: (i) junior to the Company's Series B Convertible Preferred Stock and Series C Convertible Preferred Stock; (ii) senior to the Common Stock; and (iii) at least pari passu with any other class or series of capital stock thereafter created, in each case as to distribution of assets upon voluntary or involuntary liquidation or dissolution. Voting Holders of Series D Preferred Stock are entitled to one vote per share on all matters submitted to stockholders for a vote. While any shares of Series D Preferred Stock are outstanding, the Company may not, without the approval of holders of at least a majority of the outstanding shares of Series D Preferred Stock voting as a separate class: (i) change the rights, preferences or privileges of the Series D Preferred Stock or any capital stock of the Company so as to affect adversely the Series D Preferred Stock; (ii) create any new class or series of securities senior to or on a parity with the Series D Preferred Stock; (iii) redeem or purchase any shares of Series D Preferred Stock; (iv) increase the number of authorized shares of Series D Preferred Stock; (v) increase the par value of the Common Stock; (vi) at any time more than six months after the date of issuance, sell, lease or otherwise dispose of all or substantially all of its assets or properties, or approve any sale, lease or other disposition of all or substantially all of the assets or properties of any subsidiary; (vii) at any time more than six months after the date of issuance, enter into any merger or consolidation, or approve any merger or 6 consolidation involving a subsidiary (other than one in which the holders of voting capital stock of the Company or such subsidiary immediately prior to such merger or consolidation continue to hold at least a majority by voting power of the surviving or acquiring corporation or, if the surviving or acquiring corporation is a subsidiary of another corporation immediately following such merger or consolidation, the parent corporation of such surviving or resulting corporation); or (viii) approve any dissolution or liquidation of the Company. Liquidation Upon voluntary or involuntary liquidation or dissolution of the Company, each holder of the Series D Preferred Stock will be entitled to receive before any distributions are made to holders of any junior shares, an amount per share equal to the sum of (i) the stated value plus (ii) the per share amount of accrued and unpaid dividends. After payment of all such preferential amounts, the remaining assets and funds of the Company shall be distributed among the holders of shares of Series D Preferred Stock, Common Stock and any other class or series of stock entitled to participate in liquidation distributions with the holders of Common Stock, pro rata based on the number of shares of Common Stock held by each (assuming conversion into Common Stock of all such shares). Certain corporate events including a consolidation or merger in which the stockholders of the Company do not continue to own at least 50% of the voting power of the acquiring company or a sale of all or substantially all of the assets of the Company, shall be deemed to be liquidation events. Mandatory Redemption On the seventh anniversary of the date of the initial issuance of the Series D Preferred Stock, the Company will be required to redeem all of the outstanding shares of Series D Preferred Stock at a redemption price equal to the sum of the stated value per share plus any accrued and unpaid dividends. Automatic Conversion In the event that the stockholders of the Company shall at any meeting of stockholders approve the Conversion, by a majority of votes cast at such a meeting, all of the outstanding shares of Series D Preferred Stock will automatically be converted into an aggregate of 1,809,045 shares of Common Stock, subject to customary adjustments for stock splits and similar events. Upon the Conversion, Digital, as the holder of all outstanding shares of Series D Preferred Stock, will receive 1,809,045 shares of Common Stock. Reason for the Conversion and Certain Considerations Under the Purchase and Contribution Agreement, the Company agreed to promptly prepare and file with the Securities and Exchange Commission this Proxy Statement, call the Meeting and use its best efforts to obtain stockholder approval of the Conversion. 7 The Board of Directors is of the opinion that the Conversion is advisable and in the best interests of the Company and its stockholders. Stockholders should consider the following possible effects, as well as the other information contained in this Proxy Statement, in evaluating the Conversion. Consequences if this Proposal is Not Approved To the extent that the date of the Conversion is postponed or delayed, the annual return rate received by the holders of Series D Preferred Stock increases every six-month period up to a maximum of 16.0%. If the shares of Series D Preferred Stock are not converted prior to the seventh anniversary of the date of their issuance, the Company will be required to redeem all then outstanding shares of Series D Preferred Stock for $180,000,000, plus all accrued but unpaid dividends. At the time of such redemption, the Company may not have sufficient funds available for redemption, or may have allocated such funds for other capital purposes which it will have determined are in the best interests of the Company and its stockholders. Upon any liquidation or deemed liquidation of the Company, holders of Series D Preferred Stock will be entitled to receive the sum of the stated value of such shares, accrued and unpaid dividends and the ratable distribution, if any, made in respect of the Common Stock. Until any Conversion, the Company may not, without the approval of the holders of at least a majority of the outstanding shares of Series D Preferred Stock, voting as a separate class, take any of the actions described above under "Series D Preferred Stock of the Company - Voting." Consequences if this Proposal is Approved After the Conversion, the holder of Series D Preferred Stock will no longer be entitled to receive any preferential dividends or distributions or any redemption rights. In addition, the holder of Series D Preferred Stock will no longer have any special voting rights as to any matters. After the Conversion, the holder of Series D Preferred Stock will have the right to cast an aggregate of 1,809,045 votes on all matters submitted to a vote of the holders of Common Stock. THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE IN FAVOR OF THE CONVERSION INTO COMMON STOCK OF ALL OF THE OUTSTANDING SHARES OF SERIES D PREFERRED STOCK. THE BOARD OF DIRECTORS HOPES THAT STOCKHOLDERS WILL ATTEND THE MEETING. WHETHER OR NOT YOU PLAN TO ATTEND, YOU ARE URGED TO COMPLETE, SIGN, DATE, AND RETURN THE ENCLOSED PROXY IN THE ACCOMPANYING ENVELOPE. PROMPT RESPONSE WILL GREATLY FACILITATE ARRANGEMENTS FOR THE MEETING AND YOUR COOPERATION IS APPRECIATED. 8 GENERAL Other Matters The Board of Directors knows of no other business which will be presented for consideration at the Meeting other than that described above. However, if any other business should properly come before the Meeting, it is the intention of the persons named in the enclosed proxy to vote, or otherwise act, in accordance with their best judgment on such matters. Stockholder Proposals for 1999 Annual Meeting Any proposal that a stockholder of the Company wishes to be considered for inclusion in the Company's proxy materials for its 1999 Annual Meeting of Stockholders pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), must be received by the Secretary of the Company at its offices, 100 Brickstone Square, First Floor, Andover, Massachusetts 01810 no later than ______, 1999.

The Secretary must receive such notice no later than _________, 1999. If a stockholder fails to provide timely notice of a proposal to be presented at the 1999 Annual Meeting, the proxies designated by the Board of Directors of the Company will have discretionary authority to vote on that proposal if it is properly brought before the 1999 Annual Meeting. Costs of Solicitation The cost of solicitation of proxies, including expenses in connection with preparing and mailing this Proxy Statement, will be borne by the Company.
