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.</FONT>

<P>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<FONT size=2 face="serif">(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 the provisions
described under &#147;Item 6 -- Indemnification of Directors and Officers&#148; above, 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>

Item 4: Description of Securities.
Not Applicable.
Item 5: Interests of Named Experts and Counsel.
Not Applicable.
Item 6. Indemnification of Directors and Officers.
Delaware General Corporation Law
Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by
reason of such person being or having been a director, officer, employee or agent to Ultra Clean Holdings, Inc. The Delaware General Corporation Law provides that Section 145 is not exclusive of other rights to which those seeking indemnification
may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.
Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable
to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for any breach of the director's duty of loyalty to the corporation or its stockholders, for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of law, for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions, or for any transaction from which the director derived an
improper personal benefit.
Amended and Restated Certificate of Incorporation and Bylaws
Article 8 of Ultra Clean Holdings, Inc.'s amended and restated certificate of incorporation provides that a director of Ultra Clean Holdings, Inc. shall not be liable to Ultra Clean
Holdings, Inc. or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by Delaware law. In addition, Article 8 of Ultra Clean Holdings, Inc.'s amended and restated certificate of
incorporation provides that each person (and the heirs, executors or administrators of such person) who was or is a party or is threatened to be made a party to, or is involved in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director of Ultra Clean Holdings, Inc. or is or was serving at the request of Ultra Clean Holdings, Inc. as a director of another
corporation,
2
partnership, joint venture, trust or other enterprise, shall be indemnified and held harmless by Ultra Clean Holdings, Inc. to the fullest extent permitted by Delaware law. The right to indemnification conferred in Article
8 also includes the right to be paid by Ultra Clean Holdings, Inc. the expenses incurred in connection with any such proceeding in advance of its final disposition to the fullest extent authorized by Delaware law.
Article 8 of Ultra Clean Holdings, Inc.'s amended and restated certificate of incorporation provides that Ultra Clean Holdings, Inc. may, by action of its board of directors, provide
indemnification to such of the officers, employees and agents of Ultra Clean Holdings, Inc. to such extent and to such effect as its board of directors shall determine to be appropriate and authorized by Delaware law. Article 8 also provides that
Ultra Clean Holdings, Inc. shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of Ultra Clean Holdings, Inc. or is or was serving at the request of Ultra Clean Holdings,
Inc. as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss incurred by such person in any such capacity or arising out of his status as such,
whether or not Ultra Clean Holdings, Inc. would have the power to indemnify him against such liability under Delaware law.
Indemnification Agreements and Directors' and Officers' Liability Insurance
The Registrant has entered into indemnification agreements with its directors and officers. The indemnification agreements provide indemnification to such directors and officers under certain
circumstances for acts or omissions which may not be covered by directors' and officers' liability insurance. The Registrant also intends to obtain directors' and officers' liability insurance, which insures against liabilities
that its directors or officers may incur in such capacities.
Registration Rights Agreement
Section 2.04 of the Registration Rights Agreement dated as of December 2, 2002 between Ultra Clean Holdings, Inc. and FP-Ultra Clean, LLC, the Registrant's majority shareholder (the
"Registration Rights Agreement"), provides that Ultra Clean Holdings, Inc. will indemnify and hold harmless FP-Ultra Clean, LLC and certain other persons (together, the "Shareholders") holding securities covered by a registration
statement ("Registrable Securities"), its officers, directors, employees, partners and agents, and each person, if any, who controls such Shareholder within the meaning of Section 15 of the Securities Act of 1933, as amended, or Section 20
of the Securities Exchange Act of 1934, as amended, from and against any and all losses, claims, damages, liabilities and expenses (including reasonable expenses of investigation and reasonable attorneys' fees and expenses)
("Damages") caused by or relating to any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities (as amended or supplemented if Ultra
Clean Holdings, Inc. shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by or relating to any omission or alleged omission to state therein a material fact required to be stated therein or necessary
to make the statements therein not misleading, except insofar as such Damages are caused by or related to any such untrue statement or omission or alleged untrue statement or omission so made based upon information furnished in writing to Ultra
Clean Holdings, Inc. by such Shareholder or on such Shareholder's behalf expressly for use therein, provided that, with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus, or
in any prospectus, as the case may be, the indemnity agreement contained in this paragraph shall not apply to the extent that any Damages result from the fact that a current copy of the prospectus (or such amended or supplemented prospectus, as the
case may be) was not sent or given to the person asserting any such Damages at or prior to the written confirmation of the sale of the Registrable Securities concerned to such person if it is determined that Ultra Clean Holdings, Inc. has provided
such prospectus to such Shareholder and it was the responsibility of such Shareholder to provide such person with a current copy of the prospectus (or such amended or supplemented prospectus, as the case may be) and such current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be) would have cured the defect giving rise to such Damages. Ultra Clean Holdings, Inc. also agreed to indemnify any underwriters of the Registrable Securities, their officers
and directors and each person who controls such underwriters within the meaning of Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934, as amended, on substantially the same basis as that of the
indemnification of the Shareholders as provided above.
Item 7: Exemption From Registration Claimed.

Item 9: Undertakings.
(a) The undersigned Registrant hereby undertakes:
(1) 	   To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to include any material information with respect to the plan
of distribution not previously disclosed in the Registration Statement or any material change to such information in the 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 the 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 the provisions
described under "Item 6 -- Indemnification of Directors and Officers" above, 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.
