                  NOW, THEREFORE, in consideration of the foregoing and the
covenants and agreements set forth in this Agreement, and intending to be

                  1. Termination. Lycos, TMCS and Newco mutually consent to
terminate the Merger Agreement pursuant to Section 11.1(a) of the Merger

the termination of the Transaction Agreements, none of the parties hereto nor
their respective subsidiaries, officers, directors, 

employees, agents or representatives shall have any liability or obligation under the Transaction Agreements. 3. Payment of Certain Fees. (a) If a Triggering Event described in paragraph (i) of Section 3(c) below occurs on or prior to July 15, 1999, then within 2 business days of the occurrence of such Triggering Event, Lycos will pay (x) to USAi the sum of $25.5 million in cash and (y) to TMCS the sum of $9.5 million in cash.

(c) A "Triggering Event" shall mean any of the following events or transactions occurring on or after the date hereof: (i) Lycos shall have entered into an agreement to engage in an Acquisition Transaction (as defined below) with any person (the term "person" for purposes of this Agreement having the meaning assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations thereunder) other than USAi, TMCS or any of their respective Subsidiaries or the Board of Directors of Lycos shall have recommended that the stockholders of Lycos approve or accept any Acquisition Transaction.

erwise) of beneficial ownership (the term "beneficial ownership" for purposes of this Agreement having the meaning assigned thereto in Section 13(d) of the Exchange Act, and the rules and regulations thereunder, but without regard to the passage of time) of securities representing 20% or more of the voting power of Lycos in any transaction or series of related transactions unless such Acquisition Transaction referred to in this clause (y) consists solely of an acquisition of a person and/or assets by Lycos in which Lycos issues securities of Lycos and following such Acquisition Transaction, Lycos will control such assets and/or a majority of the voting power of such person, as applicable, and such person (including any affiliates of such person and any group in which such person is a participant) will not, directly or indirectly, control Lycos (it being agreed that a widely-dispersed public offering of securities by Lycos or a private placement of Lycos securities to a financial institution that is qualified to file a Schedule 13G under the Exchange Act shall not give rise to an Acquisition Transaction under this clause (y)), or (z) any substantially similar transaction; provided, however, that in no event shall the transactions contemplated by the merger agreement entered into on October 5, 1998, and amended and restated on November 23, 1998, by Lycos and Wired Ventures Inc. or any merger, consolidation, purchase or similar transaction involving only Lycos and one or more of its wholly owned Subsidiaries or involving only any two or more of such wholly owned Subsidiaries, be deemed to be an Acquisition Transaction. For purposes of this Agreement, "Subsidiary" shall mean with respect to any party, any corporation, partnership, limited liability company, or other organization, whether incorporated or unincorporated, which is consolidated with such party for financial reporting purposes; (ii) Lycos shall have authorized, recommended or publicly announced its intention to authorize, recommend or propose, to engage in an Acquisition Transaction with any specific person other than USAi, TMCS or any of their respective Subsidiaries or shall have announced its intention to authorize or engage in, any negotiations regarding an Acquisition Transaction with any specific person other than USAi, TMCS or any of their respective Subsidiaries, or any authorization or recommendation described in this paragraph (ii), or any proposal by Lycos to engage in an Acquisition Transaction with any specific person other than USAi, TMCS or any of their respective Subsidiaries, becomes the subject of public disclosure; or (iii) Any person other than USAi, TMCS or any of their respective Subsidiaries shall have made a bona fide proposal to Lycos or its stockholders that is or becomes the subject of public disclosure to engage in an Acquisition Transaction. None of USAi, TMCS or any of their respective Subsidiaries will encourage any person to make a proposal that is referred to in this clause (iii). -3-

(d) Notwithstanding anything to the contrary in this Agreement, the aggregate amount of fees to be paid by Lycos pursuant to this Section 3 shall not exceed $35 million. 4. Standstill. On or prior to July 15, 1999, none of USAi, TMCS or any of their respective Subsidiaries will, directly or indirectly, acquire or offer to acquire any shares of Lycos's common stock, par value $.01 per share (the "Common Stock"), or propose to the Board of Directors of Lycos, or publicly announce any proposal relating to, a merger or consolidation or similar transaction involving Lycos; provided, however, that the provisions of this Section 4 shall terminate in the event a Triggering Event described in clause (iii) of Section 3(c) above occurs. 5. Releases. Each of USAi (on its behalf and on behalf of Newco, L Merger Sub and T Merger Sub), TMCS and Lycos, hereby releases and discharges the others (and such other's directors, officers, representatives, employees, attorneys, advisors, agents, parents, subsidiaries, affiliated persons and entities, predecessors, successors and assigns and all persons acting in concert with any such party) (the "Released Persons") from all manner of claims, actions, causes of action or suits, at law or in equity, known or unknown, which each now has or hereafter can, shall, or may have by reason of any matter, cause or thing whatsoever relating to or arising out of the Transaction Agreements, excepting only any claim, action, cause of action or suit arising (a) by virtue of an undertaking or promise contained in this Termination Agreement or (b) by virtue of transactions or dealings undertaken in the ordinary course of business and not arising out of, in connection with or in any way related to the Transaction Agreements. Nothing in this Section 3 shall in any way constitute an agreement by any party hereto to indemnify any other party hereto against any third party claim or, except as specifically set forth herein, waive, release, limit or restrict any claim which any party may have against any person or entity not a party to this Termination Agreement. 6. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties. 7. Entire Agreement. This Termination Agreement and the Confidentiality Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. 8. Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Delaware (without giving effect to choice of law principles thereof). -4-
