(1)     Under the 1996 Stock Option Plan (the "OPTION PLAN"), 2,929,500 shares
        are subject to outstanding options to purchase Class A Common Stock. The
        Proposed Maximum Offering Price Per Share with respect to such 2,929,500
        shares was estimated pursuant to Rule 457(h) by reference to the
        exercise price of such options. The weighted average exercise price of
        such 2,929,500 shares subject to outstanding options under the Option
        Plan is $1.11.

(2)     Estimated in accordance with Rule 457(h) solely for the purpose of
        calculating the registration fee. The Proposed Maximum Offering Price
        Per Share was determined by reference to the fair market value of the
        Class A Common Stock (the "FMV"), or, the average of the high and low
        sale prices reported in the Nasdaq National Market on November 7, 1997.

(3)     Under the 1997 Stock Plan (the "PLAN"), 1,117,000 shares are subject to
        outstanding options to purchase Class A Common Stock. The Proposed
        Maximum Offering Price Per Share with respect to such 1,117,000 shares
        was estimated pursuant to Rule 457(h) by reference to the weighted
        average exercise price of such options, which is $11.50.

(4)     Estimated in accordance with Rule 457(h) solely for the purpose of
        calculating the registration fee. The Proposed Maximum Offering Price
        Per Share was determined to be 85% of the FMV.

(5)     Under the 1997 Director Option Plan (the "OPTION PLAN"), 70,000 shares
        are subject to outstanding options to purchase Class A common Stock. The
        Proposed Maximum Offering Price Per Share with respect to such 70,000
        shares was estimated pursuant to Rule 457(h) by reference to the
        weighted average exercise price of such options, which is $11.50.

                                     PART II


ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

        There are hereby incorporated by reference into this Registration
Statement the following documents and information heretofore filed with the
Securities and Exchange Commission (the "COMMISSION") by International
Manufacturing Services, Inc. (the "REGISTRANT"):

        1.      The Registrant's Registration Statement on Form S-1 (File No.
                333-34557), as amended (the "REGISTRATION STATEMENT"), filed
                pursuant to the Securities Act of 1933, as amended (the
                "SECURITIES ACT"), relating to the Company's initial public
                offering of its Class A Common Stock (the "OFFERING").

        2.      The description of Registrant's Class A Common Stock contained
                in the Registrant's Registration Statement on Form 8-A (File No.
                000-1018797) pursuant to Section 12 of the Exchange Act,
                including any amendment or report filed for the purpose of
                updating such description.


        All documents filed by Registrant pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Exchange Act after the date hereof, and prior to the filing of
a post-effective amendment which indicates that all securities offered hereunder
have been sold or which de-registers all securities then remaining unsold under
this registration statement, shall be deemed to be incorporated by reference
herein and to be part hereof from the date of filing of such documents.

ITEM 4. DESCRIPTION OF SECURITIES.

        Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        The validity of the issuance of shares of Class A Common Stock offered
pursuant to the Offering will be passed upon for the Registrant by Wilson
Sonsini Goodrich & Rosati, Professional Corporation ("WSGR"), Palo Alto,
California. Jeffrey D. Saper, a member of WSGR, is Secretary of the Company. As
of October 22, 1997, the effective date of the Registration Statement on Form
S-1, Mr. Saper beneficially owned 23,945 shares of Class A Common Stock and a
$31,875 principal amount 12% junior subordinated note, and certain members of
WSGR, and investment partnerships of which such persons are partners,
beneficially owned 23,006 shares of Class A Common Stock and $30,625 principal
amount 12% junior subordinated notes.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's certificate of incorporation includes a provision that eliminates
the personal liability of its directors for monetary damages for breach or
alleged breach of their duty of care to the Company or its stockholders. In
addition, as permitted by Section 145 of the Delaware General Corporation Law,
the certificate of incorporation of the Registrant provides, inter alia, that
each person who is made a party or is threatened to be made a party to or
otherwise involved in any action, suit or proceeding, whether


                                      II-1
<PAGE>   4
civil, criminal, administrative or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she is or was a director or officer of the
Company or, while a director or officer of the Company, is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan (hereinafter an
"indemnitee"), whether the basis of such proceeding is alleged action in an
official capacity as a director or officer or in any other capacity while
serving as a director or officer, shall be indemnified and held harmless by the
Company to the fullest extent authorized by the Delaware General Corporation
Law, as the same exists or may hereafter be amended, against all expense,
liability and loss (including attorney's fees, judgements, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith and such indemnification
shall continue as to an indemnitee's heirs, executors and administrators;
provided, however, that, except with respect to the proceedings brought by an
indemnitee to enforce rights to indemnification (subject to certain restrictions
and as more fully described in the Registrant's certificate of incorporation),
the Company shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if such proceeding (or any
part thereof) was authorized by the Board of Directors of the Company. The right
to indemnification conferred in the Registrant's certificate of incorporation
includes the right to be paid by the Company the expenses incurred in connection
with any such proceeding in advance of its final disposition; provided, however,
that, if and to the extent that the Delaware General Corporation Law requires,
such an advancement of expenses incurred by an indemnitee in his or her capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service with respect to an employee benefit plan, shall be made only
upon delivery to the Company of an undertaking by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that such indemnitee is not entitled to be indemnified for such expenses
under the Company's certificate of incorporation or otherwise.

                 The Registrant's policy is to enter into indemnification
agreements with each of its directors and executive officers that provide the
maximum indemnity allowed directors and executive officers by Section 145 of the
Delaware General Corporation Law and the bylaws, as well as certain additional
procedural protections. The indemnity agreements provide that all directors and
executive officers will be indemnified to the fullest possible extent not
prohibited by law against all expenses (including attorney's fees) and
settlement amounts paid or incurred by them in any action or proceeding,
including any derivative action by or in the right of the Registrant, on account
of their services as directors or executive officers of the Registrant or as the
directors or officers of any other Company or enterprise when they are serving
in such capacities at the request of the Registrant. Pursuant to the indemnity
agreements, the Company will not be obligated to indemnify or advance expenses
to an indemnified party with respect to proceedings or claims initiated by the
indemnified party and not by way of defense, except with respect to proceedings
specifically authorized by the Board of Directors or brought to enforce a right
of indemnification under such indemnity agreement, the Company's certificate of
incorporation, bylaws or any statute or law, or as otherwise required by Section
145 of the Delaware General Corporation Law. Also under the indemnity
agreements, the Company is not obligated to indemnify the indemnified party for
(i) any expenses incurred by the indemnified party with respect to any
proceeding instituted by the indemnified party to enforce or interpret the
agreement, if a court of competent jurisdiction determines that each of the
material assertions made by the indemnified party in such proceeding was not
made in good faith or was frivolous, (ii) acts, omissions or transactions on the
part of the indemnified party from which such party may not be relieved of
liability under applicable law, or (iii) expenses and the payment of profits
arising from the purchase and sale by the indemnified party of securities in
violation of Section 16(b) of the Exchange Act, or any similar successor
statute.

        The indemnification provisions in the certificate of incorporation and
the indemnification agreements entered into by and between the Registrant and
its directors and officers, may be sufficiently broad to permit indemnification
of the Registrant's officers and directors for liabilities arising under the
1933 Act.

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.


                                      II-3
<PAGE>   6
        (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 foregoing 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.

                                     PART II

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

        There are hereby incorporated by reference into this Registration
Statement the following documents and information heretofore filed with the
Securities and Exchange Commission (the "COMMISSION") by International
Manufacturing Services, Inc. (the "REGISTRANT"):

        1.      The Registrant's Registration Statement on Form S-1 (File No.
                333-34557), as amended (the "REGISTRATION STATEMENT"), filed
                pursuant to the Securities Act of 1933, as amended (the
                "SECURITIES ACT"), relating to the Company's initial public
                offering of its Class A Common Stock (the "OFFERING").

        2.      The description of Registrant's Class A Common Stock contained
                in the Registrant's Registration Statement on Form 8-A (File No.
                000-1018797) pursuant to Section 12 of the Exchange Act,
                including any amendment or report filed for the purpose of
                updating such description.

        All documents filed by Registrant pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Exchange Act after the date hereof, and prior to the filing of
a post-effective amendment which indicates that all securities offered hereunder
have been sold or which de-registers all securities then remaining unsold under
this registration statement, shall be deemed to be incorporated by reference
herein and to be part hereof from the date of filing of such documents.

ITEM 4. DESCRIPTION OF SECURITIES.

        Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

        The validity of the issuance of shares of Class A Common Stock offered
pursuant to the Offering will be passed upon for the Registrant by Wilson
Sonsini Goodrich & Rosati, Professional Corporation ("WSGR"), Palo Alto,
California. Jeffrey D. Saper, a member of WSGR, is Secretary of the Company. As
of October 22, 1997, the effective date of the Registration Statement on Form
S-1, Mr. Saper beneficially owned 23,945 shares of Class A Common Stock and a
$31,875 principal amount 12% junior subordinated note, and certain members of
WSGR, and investment partnerships of which such persons are partners,
beneficially owned 23,006 shares of Class A Common Stock and $30,625 principal
amount 12% junior subordinated notes.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's certificate of incorporation includes a provision that eliminates
the personal liability of its directors for monetary damages for breach or
alleged breach of their duty of care to the Company or its stockholders. In
addition, as permitted by Section 145 of the Delaware General Corporation Law,
the certificate of incorporation of the Registrant provides, inter alia, that
each person who is made a party or is threatened to be made a party to or
otherwise involved in any action, suit or proceeding, whether

                                      II-1
4
civil, criminal, administrative or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she is or was a director or officer of the
Company or, while a director or officer of the Company, is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan (hereinafter an
"indemnitee"), whether the basis of such proceeding is alleged action in an
official capacity as a director or officer or in any other capacity while
serving as a director or officer, shall be indemnified and held harmless by the
Company to the fullest extent authorized by the Delaware General Corporation
Law, as the same exists or may hereafter be amended, against all expense,
liability and loss (including attorney's fees, judgements, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith and such indemnification
shall continue as to an indemnitee's heirs, executors and administrators;
provided, however, that, except with respect to the proceedings brought by an
indemnitee to enforce rights to indemnification (subject to certain restrictions
and as more fully described in the Registrant's certificate of incorporation),
the Company shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if such proceeding (or any
part thereof) was authorized by the Board of Directors of the Company. The right
to indemnification conferred in the Registrant's certificate of incorporation
includes the right to be paid by the Company the expenses incurred in connection
with any such proceeding in advance of its final disposition; provided, however,
that, if and to the extent that the Delaware General Corporation Law requires,
such an advancement of expenses incurred by an indemnitee in his or her capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service with respect to an employee benefit plan, shall be made only
upon delivery to the Company of an undertaking by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that such indemnitee is not entitled to be indemnified for such expenses
under the Company's certificate of incorporation or otherwise.

                 The Registrant's policy is to enter into indemnification
agreements with each of its directors and executive officers that provide the
maximum indemnity allowed directors and executive officers by Section 145 of the
Delaware General Corporation Law and the bylaws, as well as certain additional
procedural protections. The indemnity agreements provide that all directors and
executive officers will be indemnified to the fullest possible extent not
prohibited by law against all expenses (including attorney's fees) and
settlement amounts paid or incurred by them in any action or proceeding,
including any derivative action by or in the right of the Registrant, on account
of their services as directors or executive officers of the Registrant or as the
directors or officers of any other Company or enterprise when they are serving
in such capacities at the request of the Registrant. Pursuant to the indemnity
agreements, the Company will not be obligated to indemnify or advance expenses
to an indemnified party with respect to proceedings or claims initiated by the
indemnified party and not by way of defense, except with respect to proceedings
specifically authorized by the Board of Directors or brought to enforce a right
of indemnification under such indemnity agreement, the Company's certificate of
incorporation, bylaws or any statute or law, or as otherwise required by Section
145 of the Delaware General Corporation Law. Also under the indemnity
agreements, the Company is not obligated to indemnify the indemnified party for
(i) any expenses incurred by the indemnified party with respect to any
proceeding instituted by the indemnified party to enforce or interpret the
agreement, if a court of competent jurisdiction determines that each of the
material assertions made by the indemnified party in such proceeding was not
made in good faith or was frivolous, (ii) acts, omissions or transactions on the
part of the indemnified party from which such party may not be relieved of
liability under applicable law, or (iii) expenses and the payment of profits
arising from the purchase and sale by the indemnified party of securities in
violation of Section 16(b) of the Exchange Act, or any similar successor
statute.

        The indemnification provisions in the certificate of incorporation and
the indemnification agreements entered into by and between the Registrant and
its directors and officers, may be sufficiently broad to permit indemnification
of the Registrant's officers and directors for liabilities arising under the
1933 Act.

S-1 (File No. 333-34557), as amended, which was declared effective by the
Commission on October 22, 1997.

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.

                                      II-3

        (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 foregoing 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.
