breach of the director's duty of loyalty to the corporation or its stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of
law, (3)&nbsp;pursuant to Section&nbsp;174 of the DGCL, which provides for liability of directors for unlawful payments of dividends or unlawful stock purchases or redemptions, or (4)&nbsp;for

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Reference
is also made to Section&nbsp;145 of the DGCL, which provides that a corporation may indemnify any person, including an officer or director, who is, or is threatened to be
made, party to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of such
corporation, by reason of the fact that such person was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the corporation's best interest and, for criminal proceedings, had no reasonable cause to believe that his conduct was unlawful. A Delaware corporation may indemnify any officer or
director in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to
be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the
expenses that such officer or director actually and reasonably incurred. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;PETCO's
certificate of incorporation and bylaws currently provide for indemnification of the officers and directors to the full extent permitted by applicable law. In addition, PETCO has
entered into indemnification agreements with its directors and officers which generally provide for indemnification of the officers and directors to the fullest extent permitted under Delaware law,
including under circumstances for which indemnification would otherwise be discretionary under Delaware law. </FONT></P>

against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not PETCO would have the power or obligation to indemnify him or her against

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to
existing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. </FONT></P>

Item 4.    Description of Securities.
Not applicable.
Item 5.    Interests of Named Experts and Counsel.
Not applicable.
Item 6.    Indemnification of Directors and Officers.
PETCO is incorporated under the laws of the State of Delaware. Reference is made to Section 102(b)(7) of the Delaware General Corporation Law, or DGCL,
which enables a corporation in
2
its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of the director's fiduciary duty, except (1) for any
breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of
law, (3) pursuant to Section 174 of the DGCL, which provides for liability of directors for unlawful payments of dividends or unlawful stock purchases or redemptions, or (4) for
any transaction from which a director derived an improper personal benefit.
Reference
is also made to Section 145 of the DGCL, which provides that a corporation may indemnify any person, including an officer or director, who is, or is threatened to be
made, party to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of such
corporation, by reason of the fact that such person was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer,
employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the corporation's best interest and, for criminal proceedings, had no reasonable cause to believe that his conduct was unlawful. A Delaware corporation may indemnify any officer or
director in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to
be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the
expenses that such officer or director actually and reasonably incurred.
PETCO's
certificate of incorporation and bylaws currently provide for indemnification of the officers and directors to the full extent permitted by applicable law. In addition, PETCO has
entered into indemnification agreements with its directors and officers which generally provide for indemnification of the officers and directors to the fullest extent permitted under Delaware law,
including under circumstances for which indemnification would otherwise be discretionary under Delaware law.
PETCO
has purchased and intends to maintain insurance on behalf of any person who is or was a director or officer of PETCO, or is or was a director or officer of PETCO serving at the
request of PETCO as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against certain liabilities asserted
against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not PETCO would have the power or obligation to indemnify him or her against
such liability under the provisions of its certificate of incorporation or bylaws.
Item 7.    Exemption from Registration Claimed.
Not applicable.
Item 8.    Exhibits.
A list of exhibits filed with this Registration Statement is set forth in the Exhibit Index and is incorporated herein by reference.

foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high
end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective
Registration Statement; and
(iii)
To
include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material
change to such information in this Registration Statement;
provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
(2)  That,
for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3)  To
remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the
offering.
(b)  The
undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the
Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(c)  Insofar
as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to
existing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
(d)  PETCO
has previously received a favorable determination letter from the Internal Revenue Service ("IRS") conerning the qualification of the Plan under Section 401(a) and
related provisions of the Internal Revenue Code of 1986, as amended. PETCO intends to submit the Plan, as currently amended and restated, and any amendments thereto, to the IRS in a timely manner,
with a request for a favorable determination letter with respect to the Plan, as so amended and restated, and will make all changes required by the IRS in order to so qualify the Plan.
