of six directors, four of whom will be designated by DLJ Merchant Banking
Partners, L.P., and two of whom will be designated by the Other Stockholders;
provided that one of the directors designated by DLJ Merchant Banking Partners,
L.P. shall not be either an "Affiliate" or an "Associate" (a) such terms are
used within the meaning of Rule 12b-2 under the Exchange Act) of the DLJ
Entities or the Other Stockholders (the "Independent Director") and such

            (b) Each Stockholder entitled to vote for the election of directors
to the Board agrees that it will vote its Shares or execute written consents, as
the case may be, and take all other necessary action (including causing the
Company to call a special meeting of stockholders) in order to ensure that the
composition of the Board is as set forth in this Section 2.1; provided that
neither the DLJ Entities, on the one hand, nor the Other Stockholders, on the
other hand, shall be required to vote for the board-designees of the other if
the aggregate number of Shares held by such other is less than 10% of such
other's Aggregate Ownership.

            2.2 Removal. Each Stockholder agrees that if, at any time, it is
then entitled to vote for the removal of directors of the Company, it will not
vote any of its Shares in favor of the removal of any director who shall have
been designated or nominated pursuant to Section 2.1 unless such removal shall
be for cause or the Persons entitled to designate or nominate such director
shall have consented to such removal in writing.

            2.3 Vacancies. If, as a result of death, disability, retirement,
resignation, removal (with or without cause) or otherwise, there shall exist or
occur any vacancy of the Board:

            (a) the Person or Persons entitled under Section 2.1 to designate or
nominate such director whose death, disability, retirement, resignation or
removal resulted in such vacancy may designate another individual (the
"Nominee") to fill such capacity and serve as a director of the Company; and

            (b) each Stockholder then entitled to vote for the election of the
Nominee as a director of the Company agrees that it will vote its Shares, or
execute a written consent, as the case may be, in order to ensure that the
Nominee is elected to the Board.

            2.4 Meetings. The Board shall hold a regularly scheduled meeting at
least once every calendar quarter.

            2.5 Action by the Board. (a) A quorum of the Board shall consist of
four directors, of whom at least three must be designees of DLJ Merchant Banking
Partners, L.P.; provided that the DLJ Entities shall have the right at any time
to increase the number of directors necessary to constitute a quorum of the
Board. All actions of the Board shall require the affirmative vote of at least a
majority of the directors at a duly convened meeting of the Board at which a
quorum is present or the unanimous written consent of the Board; provided that,
in the event there is a vacancy on the Board and an individual has been
nominated to fill such vacancy, the first order of business shall be to fill
such vacancy.

            (b) The Board may create executive, compensation and audit
committees, as well as such other committees as it may determine. The DLJ
Entities shall be entitled to majority representation on any committee created
by the Board and, to the extent not prohibited by or inadvisable under
applicable law, the Other Stockholders shall be entitled to at least one
representative on any such committee.

            2.6 Conflicting Charter or Bylaw Provisions. Each Stockholder shall
vote its Shares or execute written consents, as the case may be, and take all
other actions necessary, to ensure that the Company's Charter and Bylaws
facilitate and do not at any time conflict with any provision of this Agreement.

Rathmullen Holdings Limited shall

                                       8
<PAGE>

fulfill or have fulfilled its obligation to purchase a total of 552,000 "C"
Ordinary Shares ("Omnitron Shares") of Omnitron Services Limited with revenues
earned by the Commission Company ("Commission Company Revenues") pursuant to the
terms of the Omnitron Agreement, the Company shall issue to Melia and Graham (or
their Permitted Transferees), to the extent such Persons are still employed by
the Company, and to the Kent Trust, in each case for no additional
consideration, an aggregate number of additional Shares equal to 800,000
multiplied by a fraction the numerator of which is the number of Omnitron Shares
purchased with Commission Company Revenues and the denominator of which is
552,000, which additional Shares shall be issued to Melia and Graham (or their
Permitted Transferees) and the Kent Trust on the basis of 40%, 40% and 20%,
respectively. "Commission Company" has the meaning assigned to it in the
Omnitron Agreement and "Omnitron Agreement" means the Subscription and
Shareholders Agreement dated May 23, 1994 between Rathmullen Holdings Limited,
Omnitron Limited and Omnitron Services Limited.

            (b) The parties hereto acknowledge that the Company desires to
acquire additional contract manufacturing facilities and that such acquisitions
may require additional equity investment in the Company. The DLJ Entities (and
their Permitted Transferees) shall have the exclusive right to provide any such
additional cash equity at the same cost per Share basis as the Shares acquired
by the DLJ Entities pursuant to the Securities Purchase Agreement. In connection
with any such additional equity investment by the DLJ Entities, Melia and Graham
may invest additional cash equity at the same cost per Share basis as the DLJ
Entities in an amount up to 20% of such additional equity investment.

                            RESTRICTIONS ON TRANSFER

            3.1 General. (a) Until the earlier of (i) the tenth anniversary of
the date hereof and (ii) the date upon which the number of Shares held by the
DLJ Entities and their Permitted Transferees falls below 20% of the Aggregate
Ownership of the DLJ Entities, no Other Stockholder may, directly or indirectly,
sell, assign, transfer, grant a participation in, pledge or otherwise dispose of
("transfer") any Shares (or solicit any offers to buy or otherwise acquire, or
to take a pledge of, any Shares), except as permitted or required by Articles 3,
4 and 5 of this Agreement.

            (b) After the first anniversary of the Initial Public Offering, any
Other Stockholder may sell any Shares owned by such Stockholder to a Third Party
pursuant to Rule

                                       9
<PAGE>

144; provided that until the third anniversary of the Initial Public Offering
(the "Restriction Termination Date"), such Stockholder may sell Shares owned by
such Stockholder pursuant to this clause (b) only to the extent that, after
giving effect to such sale, the aggregate number of Shares held by such
Stockholder is at least equal to the greater of (i) 40% of such Stockholder's
Aggregate Ownership and (ii) the percentage of such Stockholder's Aggregate
Ownership that is equal to the aggregate number of shares then beneficially
owned by the DLJ Entities, without duplication, as a percentage of the DLJ
Entities' Aggregate Ownership.

            (c) After the Restriction Termination Date, any Other Stockholder
may (in addition to sales pursuant to Rule 144) sell Shares owned by such
Stockholder to a Third Party; provided that (i) the aggregate number of Shares
sold by such Stockholder in any calendar year shall not exceed 25% of such
Stockholder's Aggregate Ownership and (ii) such Shares shall not be sold to any
Person considered by the Board to be a potential competitor of, or otherwise
adverse to, the Company or any of its Stockholders.

            (d) Any Other Stockholder may, subject to the limitations set forth
in Sections 5.1(d) and 5.2(b), sell Shares owned by such Stockholder in a Public
Offering; provided that (i) in each of the first two Public Offerings, the
number of Shares that may be sold by such Stockholder in such Public Offering
shall not exceed the lesser of (x) 50% of such Stockholder's Pro Rata Portion
and (y) 20% of such Stockholder's Aggregate Ownership and (ii) thereafter, the
number of Shares that may be sold by such Stockholder in any Public Offering
shall not exceed the lesser of (x) such Stockholder's Pro Rata Portion and (y)
50% of such Stockholder's Aggregate Ownership. "Pro Rata Portion" means, with
respect to each Other Stockholder, the number or Shares beneficially owned by
such Stockholder immediately prior to any Public Offering multiplied by a
fraction the numerator of which is the number of Shares to be sold by the DLJ
Entities and their Permitted Transferees in such Public Offering and the
denominator of which is the aggregate number of shares beneficially owned by the
DLJ Entities and their Permitted Transferees, without duplication, immediately
prior to such Public Offering.

            (e) No Stockholder may transfer any Shares at any time except in
compliance with applicable federal, state or foreign securities laws.

            3.2 Legend on Share Certificates. (a) In addition to any other
legend that may be required, each certificate for Shares that is issued to any
Stockholder shall bear a legend in substantially the following form:

                                       10
<PAGE>

            "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
      1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR
      SOLD EXCEPT IN COMPLIANCE THEREWITH. THIS SECURITY IS ALSO SUBJECT TO
      ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE STOCKHOLDERS
      AGREEMENT DATED AS OF JANUARY 20, 1995, COPIES OF WHICH MAY BE OBTAINED
      UPON REQUEST FROM MANUFACTURERS' SERVICES LIMITED AND ANY SUCCESSOR
      THERETO."

            (b) If any Shares shall cease to be Registrable Stock, the Company
shall, upon the written request of the holder thereof, issue to such holder a
new certificate evidencing such Shares without the first sentence of the legend
required by Section 3.2 (a) endorsed thereon. If any Shares cease to be subject
to any restrictions on transfer set forth in this Agreement, the Company shall,
upon the written request of the holder thereof, issue to such holder a new
certificate evidencing such shares without the second sentence of the legend
required by Section 3.2(a) endorsed thereon.

            3.3 Permitted Transferees. Notwithstanding anything in this
Agreement to the contrary, any Stockholder may at any time transfer any or all
of its Shares to one or more of its Permitted Transferees without the consent of
the Board or any other Stockholder or group of Stockholders so long as (i) such
Permitted Transferee shall have agreed in writing to be bound by the terms of
this Agreement, and (ii) the transfer to such Permitted Transferee is not in
violation of applicable federal, state or foreign securities laws.

            3.4 The Trusts. (a) Each of the Trusts and its trustees shall take
all necessary action so that the provisions of the relevant trust documents are
not inconsistent or in conflict with the provisions of Articles 3, 4 and 5 and,
in the event of any inconsistency or conflict between such trust documents and
this Agreement, the provisions of this Agreement shall control.

            (b) Each of the Trusts and its trustees agree that, so long as any
Trust shall own any Shares or shares (or interest therein) of Manufacturers'
Services Limited L.L.C. USA Group ("LLC Shares"), none of the Trusts or their
trustees shall transfer any interest in such Trust to any Person other than a
Person that is a beneficiary, or a Person of a class entitled to become a
beneficiary, of such Trust on the date hereof.

            (c) Each of the Trusts and its trustees agree that, so long as any
Trust shall own any LLC Shares (or

                                       11
<PAGE>

interest therein), none of the Trusts or their trustees shall transfer any LLC
Shares (or interest therein) to any Person. Each of the Trusts and its trustees
agree that the Company or its designee shall have the option, exercisable at any
time, to purchase all of the LLC Shares (or interests therein) owned by the
Trusts for an aggregate amount equal to $1.00, to be divided among the Trusts
based on their respective proportionate interests in all such LLC Shares.

            (d) Each of the Trusts and its trustees agree that, so long as such
Trust shall beneficially own any Shares, such Trust shall not (i) conduct any
business other than the holding of cash, Shares and LLC Shares (or interest in
such LLC Shares) and (ii) incur any liabilities, whether accrued, contingent,
absolute, determined, determinable or otherwise.

                        RIGHTS TO PARTICIPATE IN A SALE;
                             RIGHTS TO COMPEL A SALE

            4.1 Right to Participate in a Sale. (a) If any of the DLJ Entities
(the "Section 4.1 Seller") proposes to sell in one or more series of related
transactions Shares constituting 40% or more of the then outstanding Shares,
calculated on a Fully Diluted basis, to a Third Party (a "Section 4.1 Sale"),
the Section 4.1 Seller shall provide written notice of such proposed Section 4.1
Sale to the Other Stockholders ("Section 4.1 Notice"); provided that none of the
rights described in this Section 4.1 shall apply (i) to transfers to Permitted
Transferees of such DLJ Entity or Entities, (ii) to transfers pursuant to a
Public Offering or Rule 144 or (iii) unless prior to or as a result of the
proposed transfer the DLJ Entities would hold less than 50% of the Aggregate
Ownership of the DLJ Entities. The Section 4.1 Notice shall identify the number
of Shares subject to the Section 4.1 Sale, the per Share consideration for which
a sale is proposed to be made (the "Section 4.1 Sale Price") and all other
material terms and conditions of the proposed Section 4.1 Sale. Each Other
Stockholder shall, as to Shares held by it, have the option, exercisable by
irrevocable written notice to the Section 4.1 Seller within 15 days after
receipt of the Section 4.1 Notice (the "Section 4.1 Notice Period"), to
participate in the Section 4.1 Sale for up to the number of Shares held by such
Stockholder as is specified in such notice to the Section 4.1 Seller (the
"Participating Shares"); provided that if the aggregate number of Shares
proposed to be sold by the Section 4.1 Seller, the other DLJ Entities, if any,
and the Other Stockholders in such Section 4.1 Sale exceeds the number of shares
that such Third Party is willing to purchase (the "Purchase Shares"), then (i)
the number of

                                       12
<PAGE>

Shares to be sold by each of the Other Stockholders participating in such
Section 4.1 Sale shall be the lesser of (A) the number of Shares specified in
the written notice to the Section 4.1 Seller and (B) an amount equal to its
Section 4.1 Pro Rata Portion of the Purchase Shares and (ii) the number of
Shares to be sold by the Section 4.1 Seller and the other DLJ Entities, if any,
shall be an amount equal to the Purchase Shares reduced by the number of Shares
to be sold by the participating Other Stockholders. "Section 4.1 Pro Rata
Portion" means, with respect to each Other Stockholder at the time of the
Section 4.1 Sale, the proportion (expressed as a percentage) that its ownership
of Shares bears to all Shares outstanding at such time. Each participating Other
Stockholder shall deliver to the Section 4.1 Seller the certificate or
certificates representing the Participating Shares of such Other Stockholder,
together with a limited Power-of-attorney authorizing the Section 4.1 Seller to
transfer such Shares pursuant to the terms and conditions set forth in the
Section 4.1 Notice. Delivery of such certificate or certificates representing
the Participating Shares to be transferred and the limited power-of-attorney
authorizing the Section 4.1 Seller to transfer such Shares shall constitute an
irrevocable acceptance of the Section 4.1 Sale by the Other Stockholder.

            (b) The per Share consideration to be paid to the Section 4.1 Seller
and each Other Stockholder participating in the Section 4.1 Sale shall be the
Section 4.1 Sale Price.

            (c) Promptly after the consummation of the sale of the Participating
Shares of the Other Stockholders pursuant to the Section 4.1 Sale, the Section
4.1 Seller shall notify such Other Stockholders thereof, shall remit to each of
such Other Stockholders the total consideration for the Participating Shares of
each such Other Stockholder transferred pursuant thereto as computed pursuant to
Section 4.1(b), and shall furnish such other evidence of the completion and time
of completion of such transfer and the terms thereof as may be reasonably
requested by such Other Stockholders.

            (d) If at the termination of the Section 4.1 Notice Period any Other
Stockholder shall not have elected to participate in the Section 4.1 Sale, such
Other Stockholder will be deemed to have waived any of and all of its rights
under this Section 4.1 with respect to the sale of any of its Shares pursuant to
such Section 4.1 Sale. The Section 4.1 Seller shall have 120 days following such
termination of the Section 4.1 Notice Period in which to sell the applicable
Shares on substantially the same terms and conditions as were contained in the
Section 4.1 Notice, at a price not higher than 110% of the price contained in
the Section 4.1 Notice. Promptly after any sale pursuant to

                                       13
<PAGE>

this Section 4.1, the Section 4.1 Seller shall notify the Company of the
consummation thereof and shall furnish such evidence of the completion thereof
(including time of completion) of such transfer and of the terms thereof as the
Company may request. If, at the end of such 120-day period, the Section 4.1
Seller has not completed the sale of all applicable Shares, the Section 4.1
Seller shall return to the Other Stockholders the limited power-of-attorney (and
all copies thereof) together with all certificates representing the Shares which
such Other Stockholders delivered for sale pursuant to this Section 4.1, and all
the restrictions on transfer contained in this Agreement with respect to Shares
owned by such Other Stockholders shall again be in effect.

            (e) Notwithstanding anything contained in this Section 4.1, there
shall be no liability on the part of any DLJ Entity to any Other Stockholder if
the sale of Shares pursuant to this Section 4.1 is not consummated for whatever
reason. Any decision as to whether to sell Shares shall be at the Section 4.1
Seller's sole and absolute discretion.

            (f) The rights of Other Stockholders described in this Section 4.1
shall terminate upon the Initial Public Offering.

            4.2 Right to Compel Participation in Certain Transfers. (a) If the
DLJ Entities (including all Permitted Transferees of the DLJ Entities) should
transfer Shares constituting not less than 100% of the Aggregate Ownership of
such DLJ Entities to any Third Party (other than pursuant to a pledge as
security for a loan) (a "Section 4.2 Sale"), the DLJ Entities may, at their
option, require all but not less than all the Other Stockholders (including all
Permitted Transferees of the Other Stockholders) to participate in such
transfer. Not later than 15 days prior to the proposed date of the Section 4.2
Sale, the DLJ Entities shall provide written notice of the Section 4.2 Sale to
the Other Stockholders ("Section 4.2 Notice") and a copy of the agreement
pursuant to which such Shares are proposed to be transferred (the "Section 4.2
Agreement"). The Section 4.2 Notice shall identify the transferee, the number of
Shares subject to the Section 4.2 Sale, the per Share consideration for which a
transfer is proposed to be made (the "Section 4.2 Sale Price") and all other
material terms and conditions of the Section 4.2 Sale. Each Other Stockholder
shall be required to participate in the Section 4.2 Sale on the terms and
conditions set forth in the Section 4.2 Notice and to tender all its Shares, as
set forth below. Within 10 days following receipt of the Section 4.2 Notice (the
"Section 4.2 Notice Period"), each of the Other Stockholders shall deliver in
escrow to a representative of the DLJ Entities designated in the Section

                                       14
<PAGE>

4.2 Notice certificates representing all Shares held by such Other Stockholder,
duly endorsed, together with all other documents required to be executed in
connection with such Section 4.2 Sale or, if such delivery is not permitted by
applicable law, an unconditional agreement to deliver such Shares pursuant to
this Section 4.2(a) at the closing for such Section 4.2 Sale against delivery to
such Other Stockholder of the consideration therefor. In the event that a Other
Stockholder should fail to deliver such certificates to the DLJ Entities, the
Company shall cause the books and records of the Company to show that such
Shares are bound by the provisions of this Section 4.2(a) and that such Shares
shall be transferred to the Third Party immediately upon surrender for transfer
by the Other Stockholder thereof.

            (b) If, within 120 days after the DLJ Entities give the Section 4.2
Notice, they have not completed the transfer of all the Shares subject to the
Section 4.2 Sale, the DLJ Entities shall return to each of the Other
Stockholders all certificates representing Shares that such Other Stockholders
delivered for transfer pursuant hereto, together with any documents in the
possession of the DLJ Entities executed by the Other Stockholders in connection
with such proposed transfer, and all the restrictions on transfer contained in
this Agreement or otherwise applicable at such time with respect to Shares owned
by the Other Stockholders shall again be in effect.

            (c) Promptly after the consummation of the transfer of Shares of the
DLJ Entities and the Other Stockholders pursuant to this Section 4.2, the DLJ
Entities shall give notice thereof to the Other Stockholders, shall remit to
each of the Other Stockholders who have surrendered their certificates the total
consideration for the Shares of such Other Stockholders transferred pursuant
thereto and shall furnish such other evidence of the completion and time of
completion of such transfer and the terms thereof as may be reasonably requested
by such Other Stockholders. The per Share consideration to be paid to the DLJ
Entities and the Other Stockholders shall be the Section 4.2 Sale Price.

            4.3 Improper Transfer. Any attempt to transfer any Shares not in
compliance with this Agreement shall be null and void and neither the Company
nor any transfer agent shall give any effect in the Company's stock records to
such attempted transfer.

                               REGISTRATION RIGHTS

            5.1 Demand Registration. (a) One or more DLJ Entities or their
Permitted Transferees may make a written request and, after the Restriction
Termination Date, the Other Stockholders may make a written request (any such
requesting Person, a "Selling Stockholder") that the Company effect the
registration under the Securities Act of such Selling Stockholder's Registrable
Stock, and specifying the intended method of disposition thereof. The Company
will promptly give written notice of such requested registration (a "Demand
Registration") at least 30 days prior to the anticipated filing date of the
registration statement relating to such Demand Registration to all other
Stockholders, and thereupon will use its best efforts to effect, as
expeditiously as possible, the registration under the Securities Act of:

            (i) the Registrable Stock that the Company has been so requested to
      register by the Selling Stockholder, then held by the Selling Stockholder;
      and

            (ii) subject to Section 5.2, all other Registrable Stock that any
      other Stockholder entitled to request the Company to effect an Incidental
      Registration (as such term is defined in Section 5.2) pursuant to Section
      5.2 (all such Stockholders, together with the Selling Stockholder, the
      "Holders") has requested the Company to register by written request
      received by the Company within 15 days after the receipt by such Holders
      of such written notice given by the Company,

all to the extent necessary to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Stock so to be
registered; provided that, subject to Sections 5.1(c) and (e), (i) the Company
shall not be obligated to effect more than four Demand Registrations for the DLJ
Entities and their Permitted Transferees collectively, on the one hand, and one
Demand Registration for the Other Stockholders collectively, on the other hand,
pursuant to this Section 5.1 and (ii) the Company will not be required to effect
more than one Demand Registration in any six-month period; and provided further
that the number of shares of Registrable Stock required to be registered by the
Selling Stockholder must (i) in the case of a Demand Registration made by one or
more DLJ Entities or their Permitted Transferees, have a fair-market value in
the reasonable opinion of DLJ Merchant Banking Partners, L.P. exercised in good
faith of at least (A) $10,000,000 if the Demand Registration would constitute an
Initial Public Offering and (B) $5,000,000 in all other

                                       16
<PAGE>

cases or (ii) in the case of a Demand Registration made by the Other
Stockholders, have a fair market value in the reasonable opinion of the managing
underwriter of at least $5,000,000.

            Notwithstanding the foregoing, in the event of a request for a
Demand Registration made by the Other Stockholders, (i) the Company shall have
the option to either (A) proceed with such Demand Registration pursuant to the
provisions of this Section 5.1 or (B) proceed with a registered primary offering
of Common Stock, in which case, the Other Stockholders shall have the rights set
forth in Section 5.2 and, subject to Sections 5.1(c) and (e), shall have no
further rights to request a Demand Registration pursuant to this Section 5.1 and
(ii) the restrictions contained in the proviso to Section 3.1(d) shall be
applicable to any such sale.

            Promptly after the expiration of the 15-day period referred to in
Section 5.1(a) (ii), the Company will notify all the Holders to be included in
the Demand Registration of the other Holders and the number of shares of
Registrable Stock requested to be included therein. The Selling Stockholder
requesting a registration under this Section 5.1(a) may, at any time prior to
the effective date of the registration statement relating to such registration,
revoke such request, without liability to any of the other Holders, by providing
a written notice to the Company revoking such request, in which case such
request, so revoked, shall not be considered a Demand Registration.

            (b) The Company will pay all Registration Expenses in connection
with any Demand Registration.

            (c) A registration requested pursuant to this Section 5.1 shall not
be deemed to have been effected unless the registration statement relating
thereto (i) has become effective under the Securities Act and (ii) has remained
effective for a period of at least 90 days (or such shorter period in which all
Registrable Stock of the Holders included in such registration has actually been
sold thereunder); provided that if after any registration statement requested
pursuant to this Section 5.1 becomes effective (i) such registration statement
is interfered with by any stop order, injunction or other order or requirement
of the Commission or other governmental agency or court solely due to the
actions or omissions to act of the Company and (ii) less than 75% of the
Registrable Stock included in such registration has been sold thereunder, such
registration statement shall be at the sole expense of the Company and shall not
be considered a Demand Registration.

                                       17

            (d) If a Demand Registration involves a Public Offering and the
managing underwriter shall advise the Company and the Selling Stockholder that,
in its view, (i) the number of Shares requested to be included in such
registration (including Common Stock which the Company proposes to be included
which is not Registrable Stock) or (ii) the inclusion of some or all of the
Shares owned by the Holders, in either case, exceeds the largest number of
Shares which can be sold without having an adverse effect on such offering,
including the price at which such Shares can be sold (the "Maximum Offering
Size"), the Company will include in such registration, in the priorities listed
below, up to the Maximum Offering Size:

            the Demand Registration was made by any DLJ Entity or its Permitted
Transferee:

            (A) first, all Benchmark Shares requested to be registered by the
      Selling Stockholder and by all other DLJ Entities and their Permitted
      Transferees (allocated, if necessary for the offering not to exceed the
      Maximum Offering Size, pro rata among such entities on the basis of the
      relative number of shares of Registrable Stock requested to be
      registered);

            (B) second, all Registrable Stock other than Benchmark Shares
      requested to be included in such registration by all DLJ Entities and
      their Permitted Transferees and any other Holder (allocated, if necessary
      for the offering not to exceed the Maximum Offering Size, pro rata among
      such DLJ Entities and their Permitted Transferees and such other Holders
      on the basis of the relative number of shares of Registrable Stock
      (excluding any Benchmark Shares) requested to be included in such
      registration); and

            (C) third, any Common Stock proposed to be registered by the
      Company; and

            the Demand Registration was made by the Other Stockholders:

            (A) first, all Shares requested to be registered by the Other
      Stockholders (allocated, if necessary for the offering not to exceed the
      Maximum Offering Size, pro rata among such entities on the basis of the
      relative number of shares of Registrable Stock requested to be
      registered);

            (B) second, all Benchmark Shares requested to be registered by the
      DLJ Entities and their Permitted Transferees (allocated, if necessary for
      the offering not to exceed the Maximum Offering Size, pro rata among

                                       18
<PAGE>

      such entities on the basis of the relative number of shares of Registrable
      Stock requested to be registered);

            (C) third, all Registrable Stock other than Benchmark Shares
      requested to be included in such registration by all DLJ Entities and
      their Permitted Transferees and any other Holder (allocated, if necessary
      for the offering not to exceed the Maximum Offering Size, pro rata among
      such DLJ Entities and their Permitted Transferees and such other Holders
      on the basis of the relative number of shares of Registrable Stock
      (excluding any Benchmark Shares) requested to be included in such
      registration); and

            (4) fourth, any Common Stock proposed to be registered by the
      Company.

            (e) If Registrable Stock representing at least 50% of the number of
Shares requested to be registered by any Person or Persons making a Demand
Registration and their Permitted Transferees is not included in any Demand
Registration, then such Stockholders may request that the Company effect an
additional registration under the Securities Act of all or part of such
Stockholders' Registrable Stock in accordance with the provisions of this
Section 5.1, and (i) the Company shall pay the Registration Expenses in
connection with such additional registration and (ii) such additional
registration shall not be considered a Demand Registration.

            (f) The Company shall not be required to effect registration
pursuant to this Section 5.1 if a majority of the Board determines in good faith
that owing to the business or market conditions or the business or financial
condition of the Company it is inappropriate at such time to undertake a public
offering of Common Stock; provided that the Company may elect not to effect
registration on such grounds only once in any three year period beginning on the
date of such election by the Company, and that within six months shall effect
such registration.

            5.2 Incidental Registration. (a) If the Company proposes to register
any of its Common Stock under the Securities Act (other than a registration (A)
on Form S-8 or S-4 or any successor or similar forms, (B) relating to Common
Stock issuable upon exercise of employee stock options or in connection with any
employee benefit or similar plan of the Company or (C) in connection with a
direct or indirect acquisition by the Company of another company), whether or
not for sale for its own account, it will each such time, subject to the
provisions of Section 5.2(b), give prompt written notice at least 30 days prior
to

                                       19
<PAGE>

the anticipated filing date of the registration statement relating to such
registration to each DLJ Entity and each Other Stockholder, which notice shall
set forth such Stockholder's rights under this Section 5.2 and shall offer such
Stockholders the opportunity to include in such registration statement such
number of shares of Registrable Stock as each such Stockholder may request (an
"Incidental Registration"). Upon the written request of any such Stockholder
made within 15 days after the receipt of notice from the Company (which request
shall specify the number of shares of Registrable Stock intended to be disposed
of by such Stockholder), the Company will use its best efforts to effect the
registration under the Securities Act of all Registrable Stock which the Company
has been so requested to register by such Stockholders, to the extent requisite
to permit the disposition of the Registrable Stock so to be registered; provided
that (I) if such registration involves a Public Offering, all such Stockholders
requesting to be included in the Company's registration must sell their
Registrable Stock to the underwriters selected as provided in Section 5.4 (f) on
the same terms and conditions as apply to the Company and (II) if, at any time
after giving written notice of its intention to register any stock pursuant to
this Section 5.2(a) and prior to the effective date of the registration
statement filed in connection with such registration, the Company shall
determine for any reason not to register such stock, the Company shall give
written notice to all such Stockholders and, thereupon, shall be relieved of its
obligation to register any Registrable Stock in connection with such
registration (without prejudice, however, to rights of any DLJ Entity or Other
Stockholder under Section 5.1). No registration effected under this Section 5.2
shall relieve the Company of its obligations to effect a Demand Registration to
the extent required by Section 5.1. The Company will pay all Registration
Expenses in connection with each registration of Registrable Stock requested
pursuant to this Section 5.2.

            (b) If a registration pursuant to this Section 5.2 involves a Public
Offering (other than in the case of a Public Offering requested by any DLJ
Entity or any of their Permitted Transferees or the Other Stockholders in a
Demand Registration; in which case the provisions with respect to priority of
inclusion in such offering set forth in Section 5.1(d) shall apply) and the
managing underwriter advises the Company that, in its view, the number of Shares
that the Company and such Stockholders intend to include in such registration
exceeds the Maximum Offering Size, the Company will include in such
registration, in the following priority, up to the Maximum Offering Size:

                                       20
<PAGE>

            (i) first, so much of the Common Stock proposed to be registered by
      the Company as would not cause the offering to exceed the Maximum Offering
      Size;

            (ii) second, all Benchmark Shares requested to be included in such
      registration statement by the DLJ Entities and their Permitted Transferees
      (allocated, if necessary for the offering not to exceed the Maximum
      Offering Size, pro rata among such entities on the basis of the relative
      number of shares of Registrable Stock requested to be so included); and

            (iii) third, all Registrable Stock other than Benchmark Shares
      requested to be included in such registration by any DLJ Entity and its
      Permitted Transferees or any Other Stockholder pursuant to this Section
      5.2 (allocated, if necessary for the offering not to exceed the Maximum
      Offering Size, pro rata among such Stockholders on the basis of the
      relative number of shares of Registrable Stock (excluding any Benchmark
      Shares) so requested to be included in such registration).

            (c) Notwithstanding the foregoing, in the event of a request for
inclusion of Shares owned by Other Stockholders pursuant to this Section 5.2,
the restrictions contained in the proviso to Section 3.1(d) shall be applicable
to any such sale.

            5.3 Holdback Agreements. If any registration of Registrable Stock
shall be in connection with a Public Offering, each DLJ Entity and its Permitted
Transferees and each Other Stockholder agrees not to effect any public sale or
distribution, including any sale pursuant to Rule 144, or any successor
provision, under the Securities Act, of any Registrable Stock, and not to effect
any such public sale or distribution of any other Common Stock of the Company or
of any stock convertible into or exchangeable or exercisable for any Common
Stock of the Company (in each case, other than as part of such Public Offering)
during the 14 days prior to the effective date of such registration statement
(except as part of such registration) or during the period after such effective
date equal to the lesser of (i) such period of time as agreed between such
managing underwriter and the Company and (ii) 180 days.

            5.4 Registration Procedures. Whenever Stockholders request that any
Registrable Stock be registered pursuant to Section 5.1 or 5.2, the Company
will, subject to the provisions of such Sections, use its best efforts to effect
the registration and the sale of such Registrable Stock in accordance with the
intended method of

                                       21
<PAGE>

disposition thereof as quickly as practicable, and in connection with any such
request:

            (a) The Company will as expeditiously as possible prepare and file
with the Commission a registration statement on any form for which the Company
then qualifies or which counsel for the Company shall deem appropriate and which
form shall be available for the sale of the Registrable Stock to be registered
thereunder in accordance with the intended method of distribution thereof, and
use its best efforts to cause such filed registration statement to become and
remain effective for a period of not less than 90 days.

            (b) The Company will, if requested, prior to filing a registration
statement or prospectus or any amendment or supplement thereto, furnish to
participating Stockholder and each underwriter, if any, of the Registrable Stock
covered by such registration statement copies of such registration statement as
proposed to be filed, and thereafter the Company will furnish to such
Stockholder and underwriter, if any, such number of copies of such registration
statement, each amendment and supplement thereto (in each case including all
exhibits thereto and documents incorporated by reference therein), the
prospectus included in such registration statement (including each preliminary
prospectus) and such other documents as such Stockholder or underwriter may
reasonably request in order to facilitate the disposition of the Registrable
Stock owned by such Stockholder.

            (c) After the filing of the registration statement, the Company will
promptly notify each Stockholder holding Registrable Stock covered by such
registration statement of any stop order issued or threatened by the Commission
and take all reasonable actions required to prevent the entry of such stop order
or to remove it if entered.

            (d) The Company will use its best efforts to (i) register or qualify
the Registrable Stock covered by such registration statement under such other
securities or blue sky laws of such jurisdictions in the United States as any
Stockholder holding such Registrable Stock reasonably (in light of such
Stockholder's intended plan of distribution) requests and (ii) cause such
Registrable Stock to be registered with or approved by such other governmental
agencies or authorities as may be necessary by virtue of the business and
operations of the Company and do any and all other acts and things that may be
reasonably necessary or advisable to enable such Stockholder to consummate the
disposition of the Registrable Stock owned by such Stockholder; provided that
the Company will not be required

                                       22
<PAGE>

to (A) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this paragraph (d), (B) subject itself
to taxation in any such jurisdiction or (C) consent to general service of
process in any such jurisdiction.

            (e) The Company will immediately notify each Stockholder holding
such Registrable Stock, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the occurrence of an event
requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable Stock, such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading and promptly prepare and make available to
each such Stockholder any such supplement or amendment.

            (f) (i) The DLJ Entities will have the right, in their sole
discretion, to select an underwriter or underwriters in connection with any
Public Offering resulting from the exercise by any such DLJ Entity or its
Permitted Transferee of a Demand Registration, which underwriter or underwriters
may include any Affiliate of any DLJ Entity and (ii) the Company will select an
underwriter or underwriters in connection with any other Public Offering. In
connection with any Public Offering, the Company will enter into customary
agreements (including an underwriting agreement in customary form) and take such
other actions as are reasonably required in order to expedite or facilitate the
disposition of Registrable Stock in any such Public Offering, including the
engagement of a "qualified independent underwriter" in connection with the
qualification of the underwriting arrangements with the NASD.

            (g) Upon the execution of confidentiality agreements in form and
substance satisfactory to the Company, the Company will make available for
inspection by any Stockholder and any underwriter participating in any
disposition pursuant to a registration statement being filed by the Company
pursuant to this Section 5.4 and any attorney, accountant or other professional
retained by any such Stockholder or underwriter (collectively, the
"Inspectors"), all financial and other records, pertinent corporate documents
and properties of the Company (collectively, the "Records") as shall be
reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any Inspectors in connection with
such registration statement. Records that the Company determines, in good

                                       23
<PAGE>

faith, to be confidential and that it notifies the Inspectors are confidential
shall not be disclosed by the Inspectors unless (i) the disclosure of such
Records is necessary to avoid or correct a misstatement or omission in such
registration statement or (ii) the release of such Records is ordered pursuant
to a subpoena or other order from a court of competent jurisdiction. Each
Stockholder agrees that information obtained by it as a result of such
inspections shall be deemed confidential and shall not be used by it as the
basis for any market transactions in the securities of the Company or its
Affiliates unless and until such is made generally available to the public. Each
Stockholder further agrees that it will, upon learning that disclosure of such
Records is sought in a court of competent jurisdiction, give notice to the
Company and allow the Company, at its expense, to undertake appropriate action
to prevent disclosure of the Records deemed confidential.

            (h) The Company will furnish to each such Stockholder and to each
such underwriter, if any, a signed counterpart, addressed to such underwriter,
of (i) an opinion or opinions of counsel to the Company and (ii) a comfort
letter or comfort letters from the Company's independent public accountants,
each in customary form and covering such matters of the type customarily covered
by opinions or comfort letters, as the case may be, as a majority of such
Stockholders or the managing underwriter therefor reasonably requests.

            (i) The Company will otherwise use its best efforts to comply with
all applicable rules and regulations of the SEC, and make available to its
stockholders, as soon as reasonably practicable, an earnings statement covering
a period of 12 months, beginning within three months after the effective date of
the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act.

            The Company may require each such Stockholder to promptly furnish in
writing to the Company such information regarding the distribution of the
Registrable Securities as the Company may from time to time reasonably request
and such other information as may be legally required in connection with such
registration.

            Each such Stockholder agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
5.4(e), such Stockholder will forthwith discontinue disposition of Registrable
Securities pursuant to the registration statement covering such Registrable
Securities until such Stockholder's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 5.4(e), and, if so directed by the

                                       24
<PAGE>

Company, such Stockholder will deliver to the Company all copies, other than any
permanent file copies then in such Stockholder's possession, of the most recent
prospectus covering such Registrable Stock at the time of receipt of such
notice. In the event that the Company shall give such notice, the Company shall
extend the period during which such registration statement shall be maintained
effective (including the period referred to in Section 5.4 (a)) by the number of
days during the period from and including the date of the giving of notice
pursuant to Section 5.4(e) to the date when the Company shall make available to
such Stockholder a prospectus supplemented or amended to conform with the
requirements of Section 5.4(e).

            5.5 Indemnification by the Company. The Company agrees to indemnify
and hold harmless each Stockholder holding Registrable Stock covered by a
registration statement, its officers, directors and agents, and each person, if
any, who controls such Stockholder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages and liabilities caused by any untrue statement or
alleged untrue statement of a material fact contained in any registration
statement or prospectus relating to the Registrable Stock (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by 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
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
furnished in writing to the Company by such Stockholder or on such Stockholder'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
such loss, claim, damage, liability or expense results from the fact that a
current copy of the prospectus (or, in the case of a prospectus, the prospectus
as amended or supplemented) was not sent or given to the person asserting any
such loss, claim, damage, liability or expense at or prior to the written
confirmation of the sale of the Registrable Stock concerned to such person if it
is determined that the Company has provided such prospectus and it was the
responsibility of such Stockholder 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

                                       25
<PAGE>

cured the defect giving rise to such loss, claim, damage, liability or expense.
The Company also agrees to indemnify any underwriters of the Registrable Stock,
their officers and directors and each person who controls such underwriters on
substantially the same basis as that of the indemnification of the Stockholders
provided in this Section 5.5.

            5.6 Indemnification by Participating Stockholders. Each Stockholder
holding Registrable Stock included in any registration statement agrees,
severally but not jointly, to indemnify and hold harmless the Company, its
officers, directors and agents and each person, if any, who controls the Company
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act to the same extent as the foregoing indemnity from the Company
to such Stockholder, but only (i) with respect to information furnished in
writing by such Stockholder or on such Stockholder's behalf expressly for use in
any registration statement or prospectus relating to the Registrable Stock, or
any amendment or supplement thereto, or any preliminary prospectus or (ii) to
the extent that any loss, claim, damage, liability or expense described in
Section 5.5 results from the fact that a current copy of the prospectus (or, in
the case of a prospectus, the prospectus as amended or supplemented) was not
sent or given to the person asserting any such loss, claim, damage, liability or
expense at or prior to the written confirmation of the sale of the Registrable
Stock concerned to such person if it is determined that it was the
responsibility of such Stockholder 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
loss, claim, damage, liability or expense. Each such Stockholder also agrees to
indemnify and hold harmless underwriters of the Registrable Securities, their
officers and directors and each person who controls such underwriters on
substantially the same basis as that of the indemnification of the Company
provided in this Section 5.6. As a condition to including Registrable Stock in
any registration statement filed in accordance with Article 5 hereof, the
Company may require that it shall have received an undertaking reasonably
satisfactory to it from any underwriter to indemnify and hold it harmless to the
extent customarily provided by underwriters with respect to similar securities.

            5.7 Conduct of Indemnification Proceedings. In case any proceeding
(including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to this Article 5,
such person (an "Indemnified Party") shall

                                       26
<PAGE>

promptly notify the person against whom such indemnity may be sought (the
"Indemnifying Party") in writing and the Indemnifying Party shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
such Indemnified Party, and shall assume the payment of all fees and expenses;
provided that the failure of any Indemnified Party so to notify the Indemnifying
Party shall not relieve the Indemnifying Party of its obligations hereunder
except to the extent that the Indemnifying Party is materially prejudiced by
such failure to notify. In any such proceeding, any Indemnified Party shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless (i) the Indemnifying
Party and the Indemnified Party shall have mutually agreed to the retention of
such counsel or (ii) in the reasonable judgment of such Indemnified Party
representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them. It is understood that the
Indemnifying Party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all such Indemnified Parties, and that all such fees
and expenses shall be reimbursed as they are incurred. In the case of any such
separate firm for the Indemnified Parties, such firm shall be designated in
writing by the Indemnified Parties. The Indemnifying Party shall not be liable
for any settlement of any proceeding effected without its written consent, but
if settled with such consent, or if there be a final judgment for the plaintiff,
the Indemnifying Party shall indemnify and hold harmless such Indemnified
Parties from and against any loss or liability (to the extent stated above) by
reason of such settlement or judgment. No Indemnifying Party shall, without the
prior written consent of the Indemnified Party, effect any settlement of any
pending or threatened proceeding in respect of which any Indemnified Party is or
could have been a party and indemnity could have been sought hereunder by such
Indemnified Party, unless such settlement includes an unconditional release of
such Indemnified Party from all liability arising out of such proceeding.

            5.8 Contribution. If the indemnification provided for in this
Article 5 is unavailable to the Indemnified Parties in respect of any losses,
claims, damages or liabilities referred to herein, then each such Indemnifying
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such losses,
claims, damages or liabilities (i) as between the Company and the Stockholders
holding Registrable Stock covered by a registration statement on the one hand
and the underwriters

                                       27
<PAGE>

on the other, in such proportion as is appropriate to reflect the relative
benefits received by the Company and such Stockholders on the one hand and the
underwriters on the other, from the offering of the Registrable Securities, or
if such allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also the relative
fault of the Company and such Stockholders on the one hand and of such
underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations and (ii) as between the Company on the one
hand and each such Stockholder on the other, in such proportion as is
appropriate to reflect the relative fault of the Company and of each such
Stockholder in connection with such statements or omissions, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and such Stockholders on the one hand and such underwriters on the other
shall be deemed to be in the same proportion as the total proceeds from the
offering (net of underwriting discounts and commissions but before deducting
expenses) received by the Company and such Stockholders bear to the total
underwriting discounts and commissions received by such underwriters, in each
case as set forth in the table on the cover page of the prospectus. The relative
fault of the Company and such Stockholders on the one hand and of such
underwriters on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company and such Stockholders or by such underwriters. The
relative fault of the Company on the one hand and of each such Stockholder on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such party,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

            The Company and the Stockholders agree that it would not be just and
equitable if contribution pursuant to this Section 5.8 were determined by pro
rata allocation (even if the underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such

                                       28
<PAGE>

Indemnified Party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 5.8, no underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Securities underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages which such underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission, and no
Stockholder shall be required to contribute any amount in excess of the amount
by which the total price at which the Registrable Securities of such Stockholder
were offered to the public exceeds the amount of any damages which such
Stockholder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. Each such Stockholder's obligation
to contribute pursuant to this Section 5.8 is several in the proportion that the
proceeds of the offering received by such Stockholder bears to the total

                        STOCKHOLDERS AGREEMENT AMENDMENT

      AMENDMENT dated as of November 26, 1999 among DLJ Investment Partners II,
L.P., a Delaware limited partnership, DLJ Investment Funding II, Inc., a
Delaware corporation, DLJ ESC II L.P., a Delaware limited partnership and DLJ
Investment Partners, L.P., a Delaware limited partnership (each a "Mezzanine
Holder" and collectively the "Mezzanine Holders"), the parties appearing on the
signature page hereto under the caption "Existing Stockholders", and
Manufacturers' Services Limited, a Delaware corporation (the "Company").

      WHEREAS, pursuant to the Preferred Stock and Warrant Subscription
Agreement dated as of November 26, 1999 (the "Subscription Agreement") among the
Company and the Mezzanine Holders, the Mezzanine Holders are acquiring from the
Company (i) shares of preferred stock, par value $.001 per share (the "Preferred
Stock"), of the Company and (ii) warrants (the "Warrants") to purchase common
stock, par value $.001 per share (the "Common Stock"), of the Company, which
will be exercisable only upon the occurrence of certain events;

      WHEREAS, the Company has previously entered into a Stockholders Agreement
dated as of January 20, 1995 (the "Stockholders Agreement") among the DLJ
Entities (as defined therein), the Founding Stockholders (as defined therein),
the Company and the other parties thereto as of the date hereof;

      WHEREAS, the Stockholders Agreement may be amended or otherwise modified
by an instrument in writing executed by the Company, with the approval of the
board of directors of the Company, and Stockholders (as defined in the
Stockholders Agreement) holding at least 95% of the outstanding Shares (as
defined in the Stockholders Agreement); and

      WHEREAS, in connection with the acquisition of the Preferred Stock and the
Warrants by the Mezzanine Holders, the Company (with the approval of the board
of directors of the Company) and Stockholders holding at least 95% of the
outstanding Shares desire to amend or otherwise modify the Stockholders
Agreement as set forth in this Amendment.

      NOW, THEREFORE, in consideration of the covenants and agreements contained
herein and the Subscription Agreement, the parties hereto amend and otherwise
modify the Stockholders Agreement as follows:

<PAGE>

      SECTION 1. Parties to Stockholders Agreement. From the date of this
Amendment, the Mezzanine Holders shall be deemed to be parties to the
Stockholders Agreement, subject to Sections 10(b) and 10(c) of this Amendment.

      SECTION 2. Definitions; Interpretation. (a) Capitalized terms used but not
defined in this Amendment shall have the meanings ascribed to them in the
Stockholders Agreement. Each reference to "hereof', "hereunder", "herein" or
"hereby" and each other similar reference and each reference to "this Agreement"
and each other similar reference contained in the Stockholders Agreement shall
from and after the date of this Amendment refer to the Stockholders Agreement as
amended hereby.

      (b) Section 1.1 of the Stockholders Agreement is amended (i) to the extent
that the following terms do not appear in Section 1.1 of the Stockholders
Agreement, by the addition of such terms and (ii) to the extent that the
following terms appear in Section 1.1 of the Stockholders Agreement, by amending
and restating such terms as follows:

      "Company Securities" means with respect to any Stockholder, the Common
Stock (and securities convertible into or exchangeable for Common Stock), the
Preferred Stock and any options, warrants (including the Warrants) or other
rights to acquire Common Stock, Preferred Stock or any other equity security
issued by the Company.

      "Registrable Stock" means any Company Securities until (i) a registration
statement covering such Company Securities has been declared effective by the
SEC and such securities have been disposed of pursuant to such effective
registration statement, (ii) such Company Securities are sold under
circumstances in which all of the applicable conditions of Rule 144 are met or
under which they may be sold pursuant to Rule 144(k) or (iii) such Company
Securities are otherwise transferred, the Company has delivered a new
certificate or other evidence of ownership for such Company Securities not
bearing the legend required pursuant to this Agreement and such Company
Securities may be resold without subsequent registration under the Securities
Act.

      (c) As used in the Stockholders Agreement, the following terms shall have
the following interpretations unless expressly provided to the contrary in this
Amendment: (i) "Other Stockholders" shall be deemed to exclude the Mezzanine
Holders and (ii) "Stockholder" shall be deemed to include the Mezzanine Holders
(subject to Section 10(b) of this Amendment).

      SECTION 3. Corporate Governance. (a) The Board shall consist of seven
directors, six of whom will be designated as set forth in Section 2.1 of the

                                       2
<PAGE>

Stockholders Agreement and one of whom will be designated by DLJ Investment
Partners II, L.P. (such director, the "Investment Partners Director"). DLJ
Merchant Banking Partners, L.P. hereby waives its right pursuant to Section 2.1
of the Stockholders Agreement to designate this seventh director.

      (b) For so long as the Mezzanine Holders shall own any Preferred Stock,
Warrants or Shares issued upon exercise of the Warrants, each other Stockholder
who is a party hereto agrees that (i) it will vote its Shares or execute written
consents, as the case may be, and take all other necessary action (including
causing the Company to call a special meeting of stockholders) in order to
ensure the election of the Investment Partners Director, (ii) if, at any time,
it is then entitled to vote for the removal of directors of the Company, it will
not vote any of its Shares in favor of the removal of the Investment Partners
Director unless such removal shall be for cause or DLJ Investment Partners II,
L.P. shall have consented to such removal in writing and (iii) the provisions of
Section 2.3 of the Stockholders Agreement shall apply mutatis mutandis.

      (c) The Investment Partners Director shall be entitled to be appointed to
such committees of the Board as may be reasonably determined by the Chairman of
the Board.

      SECTION 4. Transferability. (a) Any Mezzanine Holder may at any time
transfer any or all of its Company Securities to one or more Persons without the
consent of the Company or any other Stockholder, so long as such transfer is not
in violation of applicable federal, state or foreign securities laws. None of
the provisions of Article 3 of the Stockholders Agreement shall apply to the
Mezzanine Holders or their Company Securities, other than the provisions of
Section 3.2 relating to legends which shall apply to their Company Securities
mutatis mutandis.

      (b) Without the consent of DLJ Investment Partners II, L.P., the DLJ
Entities and their Permitted Transferees may not (i) directly or indirectly
transfer any Shares, (ii) request a Demand Registration pursuant to Section 5.1
of the Stockholders Agreement or (iii) request any Incidental Registration
pursuant to Section 5.2 of the Stockholders Agreement, other than, in the case
of clause (i), in connection with a transaction which would constitute a Change
of Control of the Company under the Certificate of Designations, Preferences and
Rights relating to the Preferred Stock. The restrictions contained in the
foregoing sentence shall expire upon the first to occur of the following: (x)
the Mezzanine Holders (defined for purposes of this Section 4(b) to exclude any
Person to whom the initial Mezzanine Holders have transferred any Company
Securities) shall cease to hold any Preferred Stock; (y) one year after the
Demand Registration rights of the Mezzanine Holders have become exercisable
pursuant to Section 6 hereof; and (z)

                                       3
<PAGE>

the Mezzanine Holders shall have failed to request Incidental Registration of
any Company Securities in connection with two registrations of Company
Securities under the Securities Act for which the Mezzanine Holders had
piggyback registration rights pursuant to Section 7 hereof. Nothing in this
Section 4(b) shall be interpreted to restrict the right of the DLJ Entities to
transfer any Shares to their Permitted Transferees in accordance with Section
3.3 of the Stockholders Agreement.

      SECTION 5. Certain Agreements Regarding a Sale. (a) The Mezzanine Holders
shall be considered "Other Stockholders" for purposes of Section 4. 1 of the
Stockholders Agreement with respect to any Shares issued upon the exercise of
the Warrants.

      (b) The Mezzanine Holders shall be considered "Other Stockholders" for the
purposes of Section 4.2 of the Stockholders Agreement with respect to the
Warrants and any Shares issued upon the exercise of the Warrants. The right of
the DLJ Entities under such Section 4.2, at their option, to require all but not
less than all the Other Stockholders (including all Permitted Transferees of the
Other Stockholders) to participate in such transfer shall be deemed to include
the right to require the Mezzanine Holders to exercise their respective Warrants
and to sell to such Third Party the Shares received as a result of such exercise
for the same consideration per Share and otherwise on the same terms and
conditions as the sale by the DLJ Entities; provided that any Mezzanine Holder
that holds Warrants the exercise price per Share of which is greater than the
per share price at which Shares are to be sold to the Third Party may, if
required by the DLJ Entities to exercise such Warrants, in place of such
exercise, submit to irrevocable cancellation thereof without any liability for
payment of any exercise price with respect thereto.

      SECTION 6. Demand Registration. The Mezzanine Holders shall have demand
registration rights with respect to their Registrable Stock on the same terms
and conditions as the demand registration rights of the DLJ Entities as set
forth in Section 5.1 of the Stockholders Agreement, and the provisions of such
Section 5.1 shall apply mutatis mutandis to the Registrable Stock of the
Mezzanine Holders as though such Mezzanine Holders were "Selling Stockholders",
subject to the following modifications:

      (a) The Mezzanine Holders may request a Demand Registration only after the
earlier to occur of the following: (i) the date that is three years from the
date of this Amendment and (ii) the date that is six months from the date of the
Initial Public Offering.

                                       4
<PAGE>

      (b) The Company shall not be obligated to effect more than three Demand
Registrations for the Mezzanine Holders.

      (c) The number of shares of Registrable Stock required to be registered by
the Mezzanine Holders in connection with a Demand Registration must have a fair
market value in the reasonable opinion of DLJ Investment Partners II, L.P.
exercised in good faith of at least $5,000,000 or, if less than $5,000,000,
constitute all of the remaining shares of Preferred Stock or Common Stock, as
the case may be, held by the Mezzanine Holders.

      (d) If a Demand Registration requested by the Mezzanine Holders involves a
Public Offering and the managing underwriter shall advise the Company and such
Mezzanine Holders that, in its view, (i) the number of Company Securities
requested to be included in such registration (including Common Stock which the
Company proposes to be included which is not Registrable Stock) or (ii) the
inclusion of some or all of the Company Securities owned by the Holders, in
either case, exceeds the Maximum Offering Size, the Company will include in such
registration Company Securities up to the Maximum Offering Size in the priority
set forth in Section 5.1(d) of the Stockholders Agreement in the case of a
Demand Registration made by a DLJ Entity or its Permitted Transferee, with the
exception that first priority shall be given to all Registrable Stock requested
to be registered by the Selling Stockholder and by all other Mezzanine Holders
(allocated, if necessary for the offering not to exceed the Maximum Offering
Size, pro rata among such entities on the basis of the relative number of shares
of Registrable Stock requested to be registered).

      (e) Counsel for the Stockholders participating in any Demand Registration
requested by the Mezzanine Holders shall be selected by the Mezzanine Holders.

      SECTION 7. Piggyback Registration Rights. The Mezzanine Holders shall have
piggyback registration rights with respect to their Registrable Stock on the
same terms and conditions as the piggyback registration rights of the DLJ
Entities and the Other Stockholders as set forth in Section 5.2 of the
Stockholders Agreement, and the provision of such Section 5.2 (other than those
of Section 5.2(c), which are not applicable) shall apply mutatis mutandis to the
Registrable Stock of the Mezzanine Holders; provided that if a registration for
which the Mezzanine Holders have piggyback registration rights involves a Public
Offering and the managing underwriter advises the Company that, in its view, the
number of Company Securities that the Company and Stockholders entitled to
participate therein intend to include in such registration exceeds the Maximum
Offering Size,

                                       5
<PAGE>

the Company will include in such registration Company Securities up to the
Maximum Offering Size in the following priority:

      (a) in the case of a Public Offering by the Company for its own account,
in the priority set forth in Section 5.2(b) of the Stockholders Agreement;
provided that (i) any Shares proposed by Mezzanine Holders exercising piggyback
registration rights to be included in such registration shall have priority
equal to the Benchmark Shares; and (ii) any Company Securities other than Shares
proposed by Mezzanine Holders exercising piggyback registration rights to be
included in such registration shall have priority below any Shares proposed to
be registered by the Company but above any Benchmark Shares;

      (b) in the case of a Public Offering requested by any DLJ Entity or any of
their Permitted Transferees, in the priority set forth in Section 5.1(d) of the
Stockholders Agreement applicable to a Demand Registration made by a DLJ Entity
or its Permitted Transferee; provided that any Company Securities proposed by
Mezzanine Holders exercising piggyback registration rights to be included in
such registration shall have priority equal to the Benchmark Shares; and

      (c) in the case of a Public Offering requested by any Other Stockholder,
in the priority set forth in Section 5.1(d) of the Stockholders Agreement
applicable to a Demand Registration made by an Other Stockholder, provided that
any Company Securities proposed by Mezzanine Holders exercising piggyback
registration rights to be included in such registration shall have priority
equal to the Shares requested to be registered by the Other Stockholders.

      SECTION 8. Holdback Agreement. With respect to any registration of
Registrable Stock in connection with a Public Offering in which the Mezzanine
Holders are selling Company Securities, the Mezzanine Holders shall be bound by
the covenants and agreements applicable to the DLJ Entities and the Other
Stockholders in Section 5.3 of the Stockholders Agreement.

      SECTION 9. Registration Procedures. The registration procedures and other
covenants and agreements contained in Sections 5.4 through 5.10 of the
Stockholders Agreement shall apply to the Mezzanine Holders.

      SECTION 10. Miscellaneous.

      (a) Redemption of Preferred Stock upon Initial Public Offering. In
connection with the Initial Public Offering, the Company agrees to use its best
efforts to redeem the Preferred Stock in accordance with Section 5(a) of the
Certificate of Designations, Preferences and Rights of the Preferred Stock,
subject

                                       6
<PAGE>

to any required approval of the lenders under the Company's senior credit
facility, which approval the Company shall use its best efforts to obtain.

      (b) Assignability. Notwithstanding Section 6.4 of the Stockholders
Agreement, any Mezzanine Holder may, in connection with a transfer of Company
Securities other than pursuant to a Public Offering, assign its rights (in whole
or in part) under the Stockholders Agreement (other than its rights under
Article 2) to another Person; provided that such Person executes and delivers to
the Company an agreement to be bound by the terms of the Stockholders Agreement
applicable to the Mezzanine Holders (such Person, following such execution and
delivery, being deemed to be a "Mezzanine Holder" for purposes of this
Amendment).

      (c) Amendment; Waiver, Termination. Section 6.5 of the Stockholders
Agreement is amended by the insertion of the following at the end thereof: ";
and provided further that any amendment or other modification of this
Agreement that would adversely affect any Mezzanine Holder may be effected
only with the consent of such Stockholder."

      (d) Notices. All notices, requests and other communications to the
Mezzanine Holders shall be given to:
