The Prospectus and Letter of Transmittal more fully describe the Exchange Offer. These materials are being forwarded to you as the beneficial owner of Old Notes carried by us for your account or benefit but not registered in your name. A tender of any Old Notes may be made only by us as the registered holder and pursuant to your instructions. Therefore, PETCO urges beneficial owners of Old Notes registered in the name of a broker, dealer, commercial bank, trust company or other nominee to contact such registered holder promptly if they wish to tender Old Notes in the Exchange Offer. Accordingly, we request instructions as to whether you wish us to tender any or all of your Old Notes held by us for your account pursuant to the terms and subject to the conditions set forth in the Prospectus and Letter of Transmittal. We urge you to read carefully the Prospectus and Letter of Transmittal before instructing us to tender your Old Notes. Your instructions to us should be forwarded as promptly as possible in order to permit us to tender Old Notes on your behalf in accordance with the provisions of the Exchange Offer. Your attention is directed to the following: 1. The Exchange Offer will expire at 5:00 p.m., New York City time on June , 2002, unless extended (such date and time, as the same may be extended, the "Expiration Date"). Tendered Old Notes may be withdrawn, subject to the procedures described in the Prospectus, at any time before the Expiration Date. 2. The Old Notes will be exchanged for the Exchange Notes at the rate of $1,000 principal amount of Exchange Notes for each $1,000 principal amount of Old Notes validly tendered and not withdrawn before the Expiration Date. The Exchange Notes will bear interest from the most recent interest payment date to which interest has been paid on the Old Notes. The Exchange Notes are substantially identical to the Old Notes, except that the Exchange Notes have been registered under the federal securities laws and will not bear any legend restricting their transfer. <Page> 3. Notwithstanding any other term of the Exchange Offer, PETCO may terminate or amend the Exchange Offer as provided in the Prospectus and will not be required to accept for exchange, or exchange any Exchange Notes for, any Old Notes not accepted for exchange prior to such termination. 4. Any transfer taxes applicable to the exchange of the Old Notes pursuant to the Exchange Offer will be paid by PETCO, except as otherwise provided in the Prospectus and in Instruction 8 of the Letter of Transmittal. 5. Based on an interpretation of the Securities Act by the staff of the Securities and Exchange Commission, PETCO believes that Exchange Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be offered for resale, resold and otherwise transferred by holders thereof without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the holder: (a) is acquiring Exchange Notes in its ordinary course of business; (b) is not engaging in, does not intend to engage in, and has no arrangement or understanding with any person to participate in, the distribution of the Exchange Notes; (c) is not an "affiliate" of PETCO, as such term is defined in Rule 405 under the Securities Act; and (d) the holder is not acting on behalf of any person who could not truthfully make these statements. To participate in the Exchange Offer, holders must represent to PETCO that each of these statements is true. If the holder is a broker-dealer that will receive Exchange Notes for its own account in exchange for Old Notes that were acquired as a result of market-making activities or other trading activities, it must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes.
