Under this shelf registration process, we may offer and sell, from time to time, any combination of common stock, preferred stock, debt securities or warrants at a total offering price not to exceed $250,000,000, in one or more classes or series, in one or more offerings and at prices and on terms that we determine at the time of the offering.

Each time we offer any of our securities under this prospectus, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplements may add, update or change information contained in this prospectus. To the extent that any statement we make in a prospectus supplement is inconsistent with statements made in this prospectus, the statements made in this prospectus will be deemed modified or superceded by those made in the prospectus supplement.

Unless the context otherwise requires, the terms "we," "our," "us," "the company," "the registrant" and "VCA Antech" refer to VCA Antech, Inc. and its consolidated subsidiaries. VCA ANTECH, INC. OUR BUSINESS We are a leading animal health care services company and operate the largest networks of veterinary diagnostic laboratories and freestanding, full-service animal hospitals in the United States. Our network of veterinary diagnostic laboratories provides sophisticated testing and consulting services used by veterinarians in the detection, diagnosis, evaluation, monitoring, treatment and prevention of diseases and other conditions affecting animals. Our animal hospitals offer a full range of general medical and surgical services for companion animals. We treat diseases and injuries, offer pharmaceutical products and perform a variety of pet wellness programs, including health examinations, diagnostic testing, routine vaccinations, spaying, neutering and dental care. DIAGNOSTIC LABORATORIES We operate the largest full-service, veterinary diagnostic laboratory network serving all 50 states. At March 31, 2004, we operated 23 diagnostic laboratories. Our state-of-the-art, automated diagnostic laboratories service a diverse client base of over 14,000 clients, and non-affiliated clients generated approximately 94% of our laboratory revenue in 2003. We connect our laboratories to our customers with what we believe is the industry's largest transportation network, which picks up an average of 23,000 to 28,000 requisitions daily through an extensive network of drivers and independent couriers. In 2003, we derived approximately 69% of our laboratory revenue from major metropolitan areas, where we offer twice-a-day pick-up service and same-day results. In addition, in these areas we generally offer to report results within three hours of pick-up. Outside of these areas, we typically provide test results to veterinarians before 8:00 a.m. the day following pick-up. Our diagnostic spectrum includes over 300 different tests in the areas of chemistry, pathology, endocrinology, serology, hematology and microbiology, as well as tests specific to particular diseases. In 2003, we performed approximately 22.5 million tests and handled roughly 8.0 million requisitions. Although modified to address the particular requirements of the species tested, the tests performed in our veterinary laboratories are similar to those performed in human clinical laboratories and utilize similar laboratory equipment and technologies. ANIMAL HOSPITALS At March 31, 2004, we operated 247 animal hospitals in 34 states that were supported by over 820 veterinarians. Subsequently, on June 1, 2004, as a result of our merger with National PetCare Centers, Inc., we acquired an additional 68 animal hospitals in 11 states. We did not previously have operations in two of these states. With the acquisition of NPC, we employed an additional 173 veterinarians. In addition to general medical and 1 surgical services, we offer specialized treatments for companion animals, including advanced diagnostic services, internal medicine, oncology, ophthalmology, dermatology and cardiology. We also provide pharmaceutical products for use in the delivery of treatments by our veterinarians and pet owners. Our facilities typically are located in high-traffic, densely populated areas and have an established reputation in the community with a stable client base. Part of our growth strategy for our animal hospital business involves the acquisition of high-quality practices whose value we believe we can increase by the services and scale we can provide. Our principal offices are located at 12401 West Olympic Boulevard, Los Angeles, California 90064. Our telephone number is (310) 571-6500. ---------------- 2 CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS Some of the statements under "Prospectus Summary" and elsewhere in this prospectus are forward-looking statements.

We may temporarily invest net proceeds from the sale of our securities in short-term securities. We will not receive any proceeds from the sale of shares of our common stock by the selling stockholder. All proceeds from those sales will be for the account of the selling stockholder. See "Selling Stockholder" and "Plan of Distribution." SELLING STOCKHOLDER We are registering 3,396,937 shares of common stock covered by this prospectus for re-offers and resales by the selling stockholder named below. We are registering these shares to permit the selling stockholder to resell the shares when it deems appropriate. The selling stockholder may resell all, a portion or none of its shares at any time. The selling stockholder may also sell, transfer or otherwise dispose of some or all of its shares of our common stock in transactions exempt from the registration requirements of the Securities Act of 1933, as amended. We do not know when or in what amounts the selling stockholder may offer shares for sale under this prospectus. The following table sets forth (i) the selling stockholder, (ii) the number of shares of common stock that the selling stockholder beneficially owns prior to the offering and the number of shares being registered for resale by the selling stockholder, and (iii) the number of shares of our common stock that will be beneficially owned by the selling stockholder upon completion of this offering, assuming that all of the shares of common stock offered by the selling stockholder under this prospectus have been sold. The number of shares of common stock outstanding as of July 22, 2004 was 40,957,118. As used in this prospectus, "selling stockholder" includes the selling stockholder named in the table below and its transferees, pledges, donees, heirs or other successors-in-interest selling shares received from the selling stockholder listed below as a gift, partnership distribution or other non-sale-related transfer after the date of this prospectus.

On September 20, 2000, we completed a leveraged recapitalization with an entity controlled by Leonard Green & Partners, L.P. In connection with that transaction, we entered into a 10-year management services agreement with Leonard Green & Partners. The agreement was terminated on November 27, 2001. The agreement provided that Leonard Green & Partners would provide general investment-banking services, management, consulting and financial planning services and transaction-related financial advisory and investment banking services to us and our subsidiaries. We paid a one-time structuring fee of $7.5 million to Leonard Green & Partners in September 2000 under the agreement. The management agreement provided that Leonard Green & Partners would receive an annual fee of $2.5 million as compensation for the general services and normal and customary fees for transaction-related services. In 2001 and 2000, we paid management fees in an aggregate amount of $2.3 million and $620,000. In connection with the termination of this agreement, we paid Leonard Green & Partners $8.0 million. John M. Baumer currently serves on our board of directors, and until July 2004, John G. Danhakl and Peter Nolan served on our board of directors. Messrs. Baumer, Danhakl and Nolan are partners of Leonard Green & Partners, L.P. PLAN OF DISTRIBUTION We currently intend to offer and sell pursuant to one or more prospectus supplements, from time to time, any combination of common stock, preferred stock, debt securities or warrants at a total offering price not to exceed $250,000,000, in one or more classes or series, in one or more underwritten or other public offerings and at prices and on terms that we determine at the time of the offering. In addition, the selling stockholder currently intends to offer and sell, from time to time, the common stock in one or more underwritten or other public offerings. However, we and/or the selling stockholder also may offer and sell our securities, as applicable: o through agents; o through a block trade in which the broker or dealer engaged to handle the block trade will attempt to sell the securities as agent, but may position and resell a portion of the block as principal to facilitate the transaction; o directly to one or more purchasers (through a specific bidding or auction process or otherwise); or o through a combination of any of these methods of sale. The distribution of our securities may be effected from time to time in one or more transactions either: o at a fixed price or prices, which may be changed; o at market prices prevailing at the time of sale; o at prices relating to the prevailing market prices; or o at negotiated prices. Offers to purchase our securities may be solicited by agents designated by us and/or the selling stockholder from time to time. Any agent involved in the offer or sale of our securities will be named, and any commissions payable by us and/or the selling stockholder to the agent will be described, in the applicable prospectus supplement. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any agent may be deemed to be an underwriter, as such term is defined in the Securities Act, of the securities so offered and sold. 6 If we and/or the selling stockholder offer and sell our securities through an underwriter or underwriters, we and/or the selling stockholder will execute an underwriting agreement with the underwriter or underwriters. The names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transactions, including compensation of the underwriters and dealers, which may be in the form of discounts, concessions or commissions, if any, will be described in the applicable prospectus supplement, which will be used by the underwriters to make resales of our securities. That prospectus supplement and this prospectus will be used by the underwriters to make resales of our securities. If underwriters are used in the sale of any of our securities in connection with this prospectus, those securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters and us and/or the selling stockholder at the time of sale. Our securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters. If any underwriter or underwriters are used in the sale of our securities, unless otherwise indicated in a related prospectus supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to some conditions precedent and that with respect to a sale of our securities the underwriters will be obligated to purchase all such securities if any are purchased. If any underwriters are involved in the offer and sale, they will be permitted to engage in transactions that maintain or otherwise affect the price of the common stock or other securities of ours. These transactions may include over-allotment transactions, purchases to cover short positions created by the underwriter in connection with the offering and the imposition of penalty bids. If an underwriter creates a short position in the common stock in connection with the offering, i.e., if it sells more shares of common stock than set forth on the cover page of the applicable prospectus supplement, the underwriter may reduce that short position by purchasing common stock in the open market. In general, purchases of common stock to reduce a short position could cause the price of the common stock to be higher than it might be in the absence of such purchases. As noted above, underwriters may also choose to impose penalty bids on other underwriters and/or selling group members. This means that if underwriters purchase common stock on the open market to reduce their short position or to stabilize the price of the common stock, they may reclaim the amount of the selling concession from those underwriters and/or selling group members who sold such common stock as part of the offering. If we and/or the selling stockholder offer and sell our securities through a dealer, we, the selling stockholder or an underwriter will sell our securities to the dealer, as principal. The dealer may then resell our securities to the public at varying prices to be determined by the dealer at the time of resale. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of our securities so offered and sold. The name of the dealer and the terms of the transactions will be set forth in the applicable prospectus supplement. We and/or the selling stockholder may solicit offers to purchase our securities directly and we and/or the selling stockholder may sell our securities directly to institutional or other investors, who may be deemed to be an underwriter within the meaning of the Securities Act with respect to any resales of those securities. The terms of these sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement. We and/or the selling stockholder may enter into agreements with agents, underwriters and dealers under which we and/or the selling stockholder may agree to indemnify the agents, underwriters and dealers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make with respect to these liabilities. The terms and conditions of this indemnification or contribution will be described in the applicable prospectus supplement. Some of the agents, underwriters or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us and/or the selling stockholder in the ordinary course of business. We and/or the selling stockholder may authorize our respective agents or underwriters to solicit offers to purchase our securities at the public offering price under delayed delivery contracts. The terms of these delayed delivery contracts, including when payment for and delivery of our securities sold will be made under the contracts and any conditions to each party's performance set forth in the contracts, will be described in the applicable prospectus supplement. The compensation received by underwriters or agents soliciting purchases of our securities under delayed delivery contracts will also be described in the applicable prospectus supplement. 7 From time to time, the selling stockholder may pledge or grant a security interest in some or all of our shares of common stock owned by it. If the selling stockholder defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell such common stock from time to time by this prospectus. The selling stockholder also may transfer and donate our common stock owned by it in other circumstances. The number of shares of our common stock beneficially owned by selling stockholder will decrease as and when the selling stockholder transfers or donates its shares of our common stock or defaults in performing obligations secured by its shares of our common stock. The plan of distribution for the securities offered and sold under this prospectus will otherwise remain unchanged, except that the transferees, donees, pledgees, other secured parties or other successors in interest will be the selling stockholder for purposes of this prospectus. Unless we specify otherwise in the related prospectus supplement, each series of securities offered by us will be a new issue with no established trading market, other than our common shares which are listed on the Nasdaq National Market. If we sell any common shares pursuant to a prospectus supplement, the shares will be listed on the Nasdaq National Market subject to official notice of issuance. We may elect to list any series of securities on any exchange, but will not be obligated to do so and may discontinue any market making at any time without notice. Therefore there may not be a liquid market for the securities. Any underwritten offering in which members of the National Association of Securities Dealers, Inc., or NASD, act as underwriters will be made in compliance with NASD Conduct Rules 2710 (Corporate Financing Rule) and 2720 (Distribution of Securities of Members and Affiliates). Pursuant to these rules, underwriting compensation, as defined in the applicable NASD Conduct Rules, will not exceed 8% in connection with the offering.

Subordinated debt securities will be paid only if all payments due under our senior indebtedness, including any outstanding senior debt securities, have been made. The prospectus supplement will describe the debt securities and the price or prices at which we will offer the debt securities. The description will include: o the title and form of the debt securities; o any limit on the aggregate principal amount of the debt securities or the series of which they are a part; o the person to whom any interest on a debt security of the series will be paid; o the date or dates on which we must repay the principal; o the rate or rates at which the debt securities will bear interest; o if any, the date or dates from which interest will accrue, and the dates on which we must pay interest; o the place or places where we must pay the principal and any premium or interest on the debt securities; o the terms and conditions on which we may redeem any debt security, if at all; o any obligation to redeem or purchase any debt securities, and the terms and conditions on which we must do so; o the denominations in which we may issue the debt securities; o the manner in which we will determine the amount of principal of or any premium or interest on the debt securities; o the currency in which we will pay the principal of and any premium or interest on the debt securities; o the principal amount of the debt securities that we will pay upon declaration of acceleration of their maturity; o the amount that will be deemed to be the principal amount for any purpose, including the principal amount that will be due and payable upon any maturity or that will be deemed to be outstanding as of any date; o if applicable, that the debt securities are defeasible and the terms of such defeasance; o if applicable, the terms of any right to convert debt securities into, or exchange debt securities for, shares of common stock or other securities or property; o whether we will issue the debt securities in the form of one or more global securities and, if so, the respective depositaries for the global securities and the terms of the global securities; 11 o the subordination provisions that will apply to any subordinated debt securities; o the events of default applicable to the debt securities and the right of the trustee or the holders to declare the principal amount of any of the debt securities due and payable; o the affirmative and negative covenants contained in the indentures; and o any other terms of the debt securities not inconsistent with the applicable indentures. We may sell the debt securities at a substantial discount below their stated principal amount. We will describe U.S. federal income tax considerations, if any, applicable to debt securities sold at an original issue discount in the prospectus supplement. An "original issue discount security" is any debt security sold for less than its face value, and which provides that the holder cannot receive the full face value if maturity is accelerated. The prospectus supplement relating to any original issue discount securities will describe the particular provisions relating to acceleration of the maturity upon the occurrence of an event of default. In addition, we will describe U.S. federal income tax or other considerations applicable to any debt securities that are denominated in a currency or unit other than U.S. dollars in the prospectus supplement. CONVERSION AND EXCHANGE RIGHTS The prospectus supplement will describe, if applicable, the terms on which you may convert debt securities into or exchange them for common stock or other securities or property. The conversion or exchange may be mandatory or may be at your option. The prospectus supplement will describe how the number of shares of common stock or other securities or property to be received upon conversion or exchange would be calculated. SUBORDINATION OF SUBORDINATED DEBT SECURITIES The indebtedness underlying the subordinated debt securities will be payable only if all payments due under our senior indebtedness, including any outstanding senior debt securities, have been made. If we distribute our assets to creditors upon any dissolution, winding-up, liquidation or reorganization or in bankruptcy, insolvency, receivership or similar proceedings, we must first pay all amounts due or to become due on all senior indebtedness before we pay the principal of, or any premium or interest on, the subordinated debt securities. In the event the subordinated debt securities are accelerated because of an event of default, we may not make any payment on the subordinated debt securities until we have paid all senior indebtedness or the acceleration is rescinded. If we experience a bankruptcy, dissolution or reorganization, holders of senior indebtedness may receive more, ratably, and holders of subordinated debt securities may receive less, ratably, than our other creditors. The indenture for subordinated debt securities may not limit our ability to incur additional senior indebtedness. FORM, EXCHANGE AND TRANSFER We will issue debt securities only in fully registered form, without coupons, and only in specified denominations and integral multiples thereof. The holder of a debt security may elect, subject to the terms of the indentures and the limitations applicable to global securities, to exchange them for other debt securities of the same series of any authorized denomination and of similar terms and aggregate principal amount. Holders of debt securities may present them for exchange as provided above or for registration of transfer, duly endorsed or with the form of transfer duly executed, at the office of the transfer agent we designate for that purpose. We will not impose a service charge for any registration of transfer or exchange of debt securities, but we may require a payment sufficient to cover any tax or other governmental charge payable in connection with the transfer or exchange. We will name the transfer agent in the prospectus supplement. We may designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, but we must maintain a transfer agent in each place where we will make payment on debt securities. 12 If we redeem the debt securities, we will not be required to issue, register the transfer of or exchange any debt security during a specified period prior to mailing a notice of redemption. We are not required to register the transfer of or exchange of any debt security selected for redemption, except the unredeemed portion of the debt security being redeemed. GLOBAL SECURITIES The debt securities may be represented, in whole or in part, by one or more global securities that will have an aggregate principal amount equal to that of all debt securities of that series. Each global security will be registered in the name of a depositary identified in the prospectus supplement. We will deposit the global security with the depositary or a custodian, and the global security will bear a legend regarding the restrictions on exchanges and registration of transfer. No global security may be exchanged in whole or in part for debt securities registered, and no transfer of a global security in whole or in part may be registered, in the name of any person other than the depositary or any nominee or successor of the depositary unless: o the depositary is unwilling or unable to continue as depositary; or o the depositary is no longer in good standing under the Exchange Act or other applicable statute or regulation. The depositary will determine how all securities issued in exchange for a global security will be registered. As long as the depositary or its nominee is the registered holder of a global security, we will consider the depositary or the nominee to be the sole owner and holder of the global security and the underlying debt securities. Except as stated above, owners of beneficial interests in a global security will not be entitled to have the global security or any debt security registered in their names, will not receive physical delivery of certificated debt securities and will not be considered to be the owners or holders of the global security or underlying debt securities. We will make all payments of principal, premium and interest on a global security to the depositary or its nominee. The laws of some jurisdictions require that some purchasers of securities take physical delivery of such securities in definitive form. These laws may prevent you from transferring your beneficial interests in a global security. Only institutions that have accounts with the depositary or its nominee and persons that hold beneficial interests through the depositary or its nominee may own beneficial interests in a global security. The depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants. Ownership of beneficial interests in a global security will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by the depositary or any such participant. The policies and procedures of the depositary may govern payments, transfers, exchanges and others matters relating to beneficial interests in a global security. We and the trustee will assume no responsibility or liability for any aspect of the depositary's or any participant's records relating to, or for payments made on account of, beneficial interests in a global security. PAYMENT AND PAYING AGENTS We will pay principal and any premium or interest on a debt security to the person in whose name the debt security is registered at the close of business on the regular record date for such interest. We will pay principal and any premium or interest on the debt securities at the office of our designated paying agent. Unless the prospectus supplement indicates otherwise, the corporate trust office of the trustee will be the paying agent for the debt securities. Any other paying agents we designate for the debt securities of a particular series will be named in the prospectus supplement. We may designate additional paying agents, rescind the designation of any paying agent or 13 approve a change in the office through which any paying agent acts, but we must maintain a paying agent in each place of payment for the debt securities. The paying agent will return to us all money we pay to it for the payment of the principal, premium or interest on any debt security that remains unclaimed for a specified period. Thereafter, the holder may look only to us for payment, as an unsecured general creditor. CONSOLIDATION, MERGER AND SALE OF ASSETS Unless we indicate otherwise in a prospectus supplement, each indenture will provide that, so long as any securities remain outstanding, we may not consolidate or enter into a share exchange with or merge into any other person, in a transaction in which we are not the surviving corporation, or sell, convey, transfer or lease our properties and assets substantially as an entirety to any person, unless: o the successor assumes our obligations under the debt securities and the indenture; and o we meet the other conditions described in the indenture. EVENTS OF DEFAULT Unless we indicate otherwise in a prospectus supplement, events of default under each indenture will include the following: o failure to pay the principal of or any premium on any debt security when due; o failure to pay any interest on any debt security when due, for more than a specified number of days past the due date; o failure to deposit any sinking fund payment when due; o failure to perform any covenant or agreement in the indenture that continues for a specified number of days after written notice has been given by the trustee or the holders of a specified percentage in aggregate principal amount of the debt securities of that series; o events of bankruptcy, insolvency or reorganization; and o any other event of default specified in the prospectus supplement. If an event of default occurs and continues, both the trustee and holders of a specified percentage in aggregate principal amount of the outstanding securities of that series may declare the principal amount of the debt securities of that series to be immediately due and payable. The holders of a specified percentage in aggregate principal amount of the outstanding securities of that series may rescind and annul the acceleration if all events of default, other than the nonpayment of accelerated principal, have been cured or waived. Except for its duties in case of an event of default, the trustee will not be obligated to exercise any of its rights or powers at the request or direction of any of the holders, unless the holders have offered the trustee reasonable indemnity. If they provide this indemnification, the holders of a specified percentage in aggregate principal amount of the outstanding securities of any series may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. No holder of a debt security of any series may institute any proceeding with respect to the indentures, or for the appointment of a receiver or a trustee, or for any other remedy, unless: o the holder has previously given the trustee written notice of a continuing event of default; 14 o the holders of a specified percentage in aggregate principal amount of the outstanding securities of that series have made a written request upon the trustee, and have offered reasonable indemnity to the trustee, to institute the proceeding; o the trustee has failed to institute the proceeding for a specified period of time after its receipt of the notification; and o the trustee has not received a direction inconsistent with the request within a specified number of days from the holders of a specified percentage in aggregate principal amount of the outstanding securities of that series. MODIFICATION AND WAIVER We and the trustee may change an indenture without the consent of any holders with respect to specific matters, including: o to fix any ambiguity, defect or inconsistency in the indenture; and o to change anything that does not materially adversely affect the interests of any holder of debt securities of any series. In addition, under the indentures, the rights of holders of a series of notes may be changed by us and the trustee with the written consent of the holders of at least a specified percentage in aggregate principal amount of the outstanding debt securities of each series that is affected. These changes may include: o extending the fixed maturity of the series of notes; o reducing the principal amount, reducing the rate of or extending the time of payment of interest, or any premium payable upon the redemption, of any debt securities; or o reducing the percentage of debt securities the holders of which are required to consent to any amendment. The holders of a specified percentage in principal amount of the outstanding debt securities of any series may waive any past default under the indenture with respect to debt securities of that series, except a default in the payment of principal, premium or interest on any debt security of that series or in respect of a covenant or provision of the indenture that cannot be amended without each holder's consent. Except in limited circumstances, we may set any day as a record date for the purpose of determining the holders of outstanding debt securities of any series entitled to give or take any direction, notice, consent, waiver or other action under the indentures. In limited circumstances, the trustee may set a record date. To be effective, the action must be taken by holders of the requisite principal amount of such debt securities within a specified period following the record date. DEFEASANCE To the extent stated in the prospectus supplement, we may elect to apply the provisions in the indentures relating to defeasance and discharge of indebtedness, or to defeasance of restrictive covenants, to the debt securities of any series. The indentures may provide that, upon satisfaction of the requirements described below, we may terminate all of our obligations under the debt securities of any series and the applicable indenture, known as legal defeasance, other than our obligation: o to maintain a registrar and paying agents and hold monies for payment in trust; o to register the transfer or exchange of the notes; and 15 o to replace mutilated, destroyed, lost or stolen notes. In addition, we may terminate our obligation to comply with any restrictive covenants under the debt securities of any series or the applicable indenture, known as covenant defeasance. We may exercise our legal defeasance option even if we have previously exercised our covenant defeasance option. If we exercise either defeasance option, payment of the notes may not be accelerated because of the occurrence of events of default. To exercise either defeasance option as to debt securities of any series, we must irrevocably deposit in trust with the trustee money and/or obligations backed by the full faith and credit of the United States that will provide money in an amount sufficient in the written opinion of a nationally recognized firm of independent public accountants to pay the principal of, premium, if any, and each installment of interest on the debt securities. We may only establish this trust if, among other things: o no event of default shall have occurred or be continuing; o in the case of legal defeasance, we have delivered to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the Internal Revenue Service a ruling or there has been a change in law, which in the opinion of our counsel, provides that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred; o in the case of covenant defeasance, we have delivered to the trustee an opinion of counsel to the effect that the holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred; and o we satisfy other customary conditions precedent described in the applicable indenture. NOTICES We will mail notices to holders of debt securities as indicated in the prospectus supplement. TITLE We may treat the person in whose name a debt security is registered as the absolute owner for the purpose of making payment and for all other purposes. GOVERNING LAW The indentures and the debt securities will be governed by and construed in accordance with the laws of the state of New York. WARRANTS The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. We may issue, together with other securities or separately, warrants to purchase our securities. We may issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant 16 agent, all as shall be set forth in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants of the series being offered and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. The applicable prospectus supplement will describe the following terms, where applicable, of warrants in respect of which this prospectus is being delivered: o the title of the warrants; o the designation, amount and terms of the securities for which the warrants are exercisable and the procedures and conditions relating to the exercise of such warrants; o the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of warrants issued with each such security; o the price or prices at which the warrants will be issued; o the aggregate number of warrants; o any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants; o the price or prices at which the securities purchasable upon exercise of the warrants may be purchased; o if applicable, the date on and after which the warrants and the securities purchasable upon exercise of the warrants will be separately transferable; o if applicable, a discussion of the material U.S. federal income tax considerations applicable to the exercise of the warrants; o any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants; o the date on which the right to exercise the warrants shall commence, and the date on which the right shall expire; o the maximum or minimum number of warrants which may be exercised at any time; and o information with respect to book-entry procedures, if any. Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any. EXERCISE OF WARRANTS Each warrant will entitle the holder thereof to purchase for cash the amount of securities at the exercise price as shall in each case be set forth in, or be determinable as set forth in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as set forth in the applicable prospectus supplement relating to the warrants offered thereby. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we 17 will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants. ENFORCEABILITY OF RIGHTS OF HOLDERS OF WARRANTS Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as a warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, that holder's warrants. ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW We are subject to Section 203 of the Delaware General Corporation Law. Section 203 provides that specified persons who, together with affiliates and associates, own, or within three years did own, 15% or more of the outstanding voting stock of a corporation cannot engage in specified business combinations with the corporation for a period of three years after the date on which the person became an interested stockholder, unless: o prior to the date, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; o upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock of the corporation outstanding at the time the transaction commenced, excluding those shares owned by persons who are directors and also officers, and employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or o on or subsequent to the date, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder. Section 203 defines "business combination" to include: o any merger or consolidation involving the corporation and the interested stockholder; o any sale, transfer, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation; o subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; or o the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation. ANTI-TAKEOVER PROVISIONS OF OUR CHARTER Our bylaws provide that candidates for director may be nominated only by the board of directors or by a stockholder who gives written notice to us generally not less than 60 days nor more than 90 days prior to the annual meeting of stockholders. The board of directors may consist of one or more members to be determined from time to time by the board of directors. The board of directors currently consists of five members divided into three different classes. As a result, only one class of directors will be elected at each annual meeting of our stockholders, with the 18 other classes continuing for the remainder of their respective terms. Between stockholder meetings, the board of directors may appoint new directors to fill vacancies or newly created directorships. Our certificate of incorporation requires that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by a consent in writing. Our certificate of incorporation also provides that the authorized number of directors may be changed only by resolution of the board of directors. Delaware law and these charter provisions may have the effect of deterring hostile takeovers or delaying changes in control of our management, which could depress the market price of our common stock. INDEMNIFICATION OF DIRECTORS AND OFFICERS AND LIMITATION OF LIABILITY Our certificate of incorporation and bylaws allow us to eliminate the personal liability of our directors and to indemnify directors and officers to the fullest extent permitted by the Delaware General Corporation law. We also entered into indemnity agreements with each of our directors and officers, which provide for mandatory indemnity of an officer or director made party to a "proceeding" by reason of the fact that he or she is or was a director of ours, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to our best interests. These agreements also obligate us to advance expenses to a director provided that he or she will repay advanced expenses in the event he or she is not entitled to indemnification. Directors are also entitled to partial indemnification, and indemnification for expenses incurred as a result of acting at our request as a director, officer or agent of an employee benefit plan or other partnership, corporation, joint venture, trust or other enterprise owned or controlled by us. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the above statutory provisions or otherwise, we have been advised that in the opinion of the Securities and Exchange Commission that indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. TRANSFER AGENT AND REGISTRAR The transfer agent and registrar for our common stock is U.S. Stock Transfer Corporation. LISTING Our common stock is quoted on The Nasdaq Stock Market's National Market under the symbol "WOOF." LEGAL MATTERS The validity of our securities will be passed upon for us by our legal counsel, Akin Gump Strauss Hauer & Feld LLP, Los Angeles, California.
