NOW THEREFORE, in consideration of the above-referenced recitals, and other good and valuable consideration, the receipt and adequacy of which is hereby conclusively acknowledged, the parties hereto intending to be legally bound, agree as follows: 1. Rights Offering. (a) As soon as reasonably practicable after the date of this Agreement, the Board of Directors of Terra will call a meeting of the Terra shareholders ("Terra Shareholders") as soon as practicable to seek their approval to delegate to the Board of Directors the power to effectuate the Rights Offering in an amount equal to the Subscription Amount, in accordance with the Spanish Corporation Law of 1989 (Texto Refundido de la Ley de Sociedades Anonimas). The Terra Shareholders shall agree that necessary terms and conditions, including in order to permit Telefonica to subscribe to the shares of the Subscription Stock in accordance with Section 2 below, shall be determined by the Board of Directors or the Delegated Committee of the Board of Directors (the "Committee") at a meeting of such Board or Committee to be held in order to carry out the Rights Offering. The per share subscription price shall be the closing price per share of the Terra Capital Stock on the Spanish Continuous Market Exchange (Systema de Interconexion Bursatil- Mercado Continuo) ("SCME") on May 16, 2000. The Rights Offering shall be effective, available for subscription, completed and the proceeds therefrom received by Terra at least ten full SCME trading days prior to the period during which the Terra Average Price is to be calculated pursuant to the terms of the Reorganization Agreement. (b) As soon as practicable following the date of this Agreement, Terra shall (i) prepare and file with the CNMV a relevant fact disclosure (hecho relevante), (ii) prepare and arrange to have a prior notice to the CMNV outlining the proposed transaction (comunicacion previa) and have registered with and verified by the CMNV a prospectus (folleto), and (iii) prepare and file with the U.S. Securities and Exchange Commission a registration statement on Form F-1 (the "Registration Statement"), if necessary, relating to the Rights Offering. Terra shall use its reasonable best efforts to have such prospectus registered, and the Registration Statement, if required, filed with and declared effective, by the relevant securities authorities as promptly as practicable after such filings. Terra shall also use its reasonable best efforts to (i) obtain all necessary state securities law or "Blue Sky" permits and approvals required to carry out the Rights Offering, (ii) make the filings with and obtain the authorization of the listing of Terra Shares on the Spanish Stock Exchange and the verification by the NSEC and the Managing Companies of the Spanish Stock Exchanges and (iii) make the filing with and obtain the approval of the Nasdaq National Market to authorize the quotation of the ADSs. 2. Telefonica Commitment. Subject to the terms and conditions of this Agreement, Telefonica agrees that it shall subscribe for all of the shares of the Subscription Stock not subscribed for by other shareholders of Terra in the Rights Offering; provided, however, that in no event shall Telefonica be required to subscribe for in excess of the entire Subscription Amount in connection with the Rights Offering. 3. Voting of Terra Shares. Telefonica agrees that it shall vote all of its Terra Shares, which Telefonica represents to constitute approximately 66.6% of the outstanding Terra Shares (all such shares, as they may be adjusted as a result of any stock split, stock dividend, reclassification, merger, reorganization, recapitalization or other change in the capital structure of Terra, as well as any Terra Shares acquired after the date hereof and prior to the meeting at which a vote of the Terra Shareholders is held in respect of the matters contemplated hereby or by the Reorganization Agreement, the "Subject Shares"), in favor of the matters to be voted upon by the holders of Terra Shares pursuant to the transaction contemplated hereby and by the Reorganization Agreement. Telefonica agrees that it shall vote all such Terra Shares against any matter upon which the Terra Shareholders are asked to vote involving any amendment of the Terra Articles or the Terra By-Laws or any proposals or transactions involving Terra or its Subsidiaries that, in any such case, would prevent or materially delay consummation of the transactions contemplated hereby or by the Reorganization Agreement or change in any manner the voting rights of any class of capital stock of Terra. 4.

Telefonica further agrees that it shall not sell, transfer, pledge, assign or otherwise dispose of (collectively, "Transfer") or enter into any 2 contract, option or other arrangement with respect to the Transfer of, or the creation or offer of any derivative security in respect of, the Subject Shares to any person or commit or agree, or announce an intention to, take any of the foregoing actions. 5.
