           INTRODUCTORY STATEMENT REGARDING TENDER OFFER OF SHARES OF
                SMARTFLEX SYSTEMS INC,. -- CUSIP NUMBER 83169K108
                                  SCHEDULE 13D


         On July 6, 1999, SSI Acquisition Corp., a Delaware corporation ("SSI")
and Saturn Electronics and Engineering, Inc., a Michigan corporation (the
"Parent") entered into an Agreement and Plan of Merger (the "Merger Agreement")
with Smartflex Systems, Inc., a Delaware Corporation (the "Company") under which
SSI would tender for all of the issued and outstanding shares of common stock of
the Company (the "Shares"). SSI and Parent entered into a Stock Tender and
Voting Agreement with each of the directors and executive officers of the
Company (all of whom are reporting persons filing this Schedule 13D) which
provided generally that such director or officer would tender his or her shares
within 10 days following commencement of the tender offer and would vote their
shares in favor of the merger of SSI with and into the Company. The Company
believes each of the directors and officers of the Company acted independently
and anticipated that the effectiveness of their respective obligations under the
Stock Tender and Voting Agreement should be conditioned upon commencement of a
tender offer in accordance with the Merger Agreement. The Company also believes
that the directors and officers did not comprise a "group" as defined in Rule
13d-5(b)(1) of the Securities Exchange Act of 1934 (the "Exchange Act") because
each of the directors and officers entered into a Stock Tender and Voting
Agreement severally with SSI and Parent and did not enter into any agreement
with the other directors and/or officers of the Company. Further, none of the
Company's executive officers' or directors' obligations under their respective
Stock Tender and Voting Agreements are conditioned upon, or are related to, the
performance by any other of the Company's executive officers or directors of the
obligations under their respective Stock Tender and Voting Agreements. If a
group was formed within the definition of Rule 13d-5(b)(1) the Company believes
that the group would have been formed only upon the commencement of the tender
offer which occurred on July 14, 1999.

         Each of the directors and officers of the Company filing this Schedule
13D is doing so as a precautionary measure but does not concede that he or she
is a member of a group or that this Statement is required under Regulation 13D
of the Exchange Act. The Company believes that if this Statement is required,
the commencement time of the 10-day period referenced in Rule 13d-1(a) would be
concurrent with the tender offer on July 14, 1999.

         The filing of this Schedule 13D shall not be construed as an admission
that the individuals signing herein are the beneficial owners of any securities
covered by this Schedule 13D.


ITEM 1.   SECURITY AND ISSUER

         The class of equity securities to which this statement on Schedule 13D
(the "Statement") relates is the common stock, par value $.0025 per share (the
"Common Stock"), of Smartflex Systems, Inc., a Delaware corporation (the
"Company"). The principal executive offices of the Company are located at 14312
Franklin Avenue, Tustin, California 92781.


ITEM 2.   IDENTITY AND BACKGROUND

         This Statement is filed on behalf of the potential members of a group
within the meaning of Rule 13d-5(b)(1) under the Securities Exchange Act of 1934
listed below (the "Individuals"). The name, business address, present principal
occupation or employment and the name, principal business and address of the
corporation in which such employment is conducted are set forth below for each
Individual.

ITEM 4.   PURPOSE OF TRANSACTION

          The purpose of each Stock Tender and Voting Agreement was to have the

purchase of all of the outstanding shares of the Company (the "Tender Offer").
Pursuant to the Stock Tender and Voting Agreements, each Individual has agreed
to tender all shares of common stock of the Company beneficially owned by them
(the "Shares") pursuant to the Tender Offer within 10 business days of
commencement of the Tender Offer. Each Individual agreed to vote the Shares in
favor of the merger of SSI with and into the Company and agreed to not take
certain specified actions which would impede the proposed merger. Furthermore,
each Individual delivered an irrevocable proxy to SSI's parent corporation,
Saturn Electronic & Engineering, Inc. (the "Parent"), pursuant to which each
Individual irrevocably appoints Wallace K. Tsuha, Jr., Jereen G. Trudell and
Parent to exercise the proxy to vote the Shares in favor of the merger of SSI
with and into the Company. Such proxies shall remain in effect until termination
of the Agreement and Plan of Merger dated July 6, 1999, by and among the

          The information required by paragraphs (a) and (b) of this Item 5 is
set forth in Items 7-13 of the cover page to this Statement for each Individual,
which information is incorporated herein by reference.

          On June 24, 1999 and effective May 18, 1999, William L. Healey, the
Company's President, Chief Executive Officer and Chairman of the Board of
Directors, terminated and waived all of his rights under the Stock Option
Agreement between the Company and Mr. Healey dated January 14, 1997. Such Stock
Option Agreement provided for the grant of options to Mr. Healey to purchase
35,000 Shares at an exercise price of $16.50 per share.

          On May 19, 1999, the Company's non-employee directors, William E.
Bendush, Alan V. King, William A. Klein and Gary E. Liebl, each received an
automatic grant of non-qualified stock options to purchase 3,000 Shares at an
exercise price of $3.50 per Share. Such options are automatically granted to
non-employee directors of the Company each time such directors are reelected to
the Board of Directors.

          Each of William L. Healey, Anthony R.W. Richardson, Christopher J.
Rollison and James Cogan are participants in the Company's 1995 Employee Stock
Purchase Plan. On May 1, 1999, Messrs. Healey, Richardson and Rollison each
purchased 1,000 Shares at a price of $2.92 per Share, pursuant to the Company's
1995 Employee Stock Purchase Plan (Mr. Cogan had not yet become a participant in
the 1995 Employee Stock Purchase Plan as of such date).

          AGREEMENT AND PLAN OF MERGER, dated as of July 6, 1999 (this
"Agreement"), among SATURN ELECTRONICS & ENGINEERING, INC., a corporation
organized under the laws of Michigan ("Parent"), SSI ACQUISITION CORP., a
Delaware corporation and a wholly owned subsidiary of Parent ("Purchaser"), and
SMARTFLEX SYSTEMS, INC., a Delaware corporation (the "Company").

                              W I T N E S S E T H:

          WHEREAS, the Boards of Directors of Parent, Purchaser and the
Company have each unanimously determined that it is in the best interests of
their respective shareholders for Parent to acquire the Company upon the terms
and subject to the conditions set forth herein;

          WHEREAS, in furtherance of such acquisition, it is proposed
that Purchaser shall make a cash tender offer (the "Offer") to acquire all the
issued and outstanding shares of common stock, $.0025 par value, of the Company
(the "Shares") for U.S. $10.50 per Share (such amount being hereinafter referred
to as the "Per Share Amount") net to the seller in cash, upon the terms and
subject to the conditions of this Agreement and the Offer;

          WHEREAS, the Board of Directors of the Company (the "Board"),
including all the disinterested directors on the Board, has unanimously approved
the making of the Offer and resolved and agreed to recommend that holders of
Shares tender their Shares pursuant to the Offer;

          WHEREAS, also in furtherance of such acquisition, the Boards
of Directors of Parent, Purchaser and the Company have each unanimously approved
the merger (the "Merger") of Purchaser with and into the Company in accordance
with the Business Corporation Act of the State of Delaware ("Delaware Law")
following the consummation of the Offer and upon the terms and subject to the
conditions set forth herein;

          WHEREAS, to induce Parent and Purchaser to enter into this
Agreement, Parent has required that Purchaser and each of the shareholders of
the Company listed on Schedule I attached hereto (the "Shareholders") enter into
a Stock Tender and Voting Agreement, dated today's date (the "Shareholder
Agreements"), pursuant to which each Shareholder agrees, among other things, to
validly tender its Shares into, and not to withdraw its Shares from, the Offer,
and to vote its Shares in favor of the Merger, in each case subject to the terms
and conditions set forth therein; and

          WHEREAS, also in furtherance of such acquisition, the Boards
of Directors of the Parent, the Purchaser and the Company have each unanimously
approved the execution, delivery and performance of the Shareholder Agreements
in accordance with applicable law.

          NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements herein contained, and intending to be legally
bound hereby, Parent, Purchaser and the Company hereby agree as follows:
<PAGE>   7


                                    ARTICLE I

                                    THE OFFER


          SECTION 1.01.  The Offer. (a) Provided that this Agreement
shall not have been terminated in accordance with Section 8.01 and none of the
events set forth in Annex A hereto shall have occurred or be existing, Purchaser
shall commence the Offer as promptly as reasonably practicable after the date
hereof, but in no event later than five business days after the date hereof. The
obligation of Purchaser to accept for payment and pay for Shares tendered
pursuant to the Offer shall be subject to the condition (the "Minimum
Condition") that at least the number of Shares that combined with the Shares
already owned by Parent, Purchaser or any of their affiliates shall constitute a
majority of the then outstanding Shares on a fully diluted basis (including,
without limitation, all Shares issuable upon the conversion of any convertible
securities or upon the exercise of any options, warrants or rights) shall have
been validly tendered and not withdrawn prior to the expiration of the Offer and
also shall be subject to the satisfaction of the other conditions set forth in
Annex A hereto. Purchaser expressly reserves the right to waive any such
condition, to increase the price per Share payable in the Offer, and to make any
other changes in the terms and conditions of the Offer; provided, however, that,
without the prior written consent of the Company, no change may be made which
decreases the price per Share payable in the Offer or which changes or waives
the Minimum Condition or which changes the form of consideration to be paid in
the Offer or which extends the period that the Offer is outstanding for one or
more periods not to exceed thirty days in the aggregate or which reduces the
maximum number of Shares to be purchased in the Offer or which imposes
conditions to the Offer in addition to those set forth in Annex A hereto. The
Per Share Amount shall, subject to applicable withholding of taxes, be paid net
to the seller in cash, upon the terms and subject to the conditions of the
Offer. Subject to the terms and conditions of the Offer (including, without
limitation, the Minimum Condition), Purchaser shall pay, as promptly as
practicable after expiration of the Offer, for all Shares validly tendered into
and not withdrawn from, the Offer.

          (b)  As soon as reasonably practicable on the date of
commencement of the Offer, Purchaser shall file with the Securities and Exchange
Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1 (together with
all amendments and supplements thereto, the "Schedule 14D-1") with respect to
the Offer and the other Transactions (as hereinafter defined), which shall have
been provided to the Company and to which the Company shall not have reasonably
objected. The Schedule 14D-1 shall contain or shall incorporate by reference an
offer to purchase (the "Offer to Purchase") and forms of the related letter of
transmittal and any related summary advertisement (the Schedule 14D-1, the Offer
to Purchase and such other documents, together with all supplements and
amendments thereto, being referred to herein collectively as the "Offer
Documents"). Each of Parent, Purchaser and the Company agree to correct promptly
any information provided by it for use in the Offer Documents which shall have
become false or misleading, and Parent and Purchaser further agree to take all
steps necessary to cause the Schedule 14D-1 as so corrected to be filed with the
SEC and the other Offer Documents as so

                                       2

<PAGE>   8

corrected to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws.

          SECTION 1.02.  Company Action. (a) The Company hereby approves
of and consents to the Offer and represents and warrants that (i) the Board, at
a meeting duly called and held on July 6, 1999, has unanimously (A) determined
that this Agreement, the Shareholder Agreements and the transactions
contemplated hereby and thereby, including, without limitation, each of the
Offer, the Merger and the tender of Shares pursuant to the Shareholder
Agreements, are fair to and in the best interests of the shareholders of the
Company, (B) approved and adopted this Agreement and the transactions,
including, without limitation, the Offer, the Merger and the tender of Shares
pursuant to the Shareholder Agreements, contemplated hereby and thereby, (C)
taken all action to render the provisions of the Rights Agreement, dated as of
July 17, 1996, between the Company and The First National Bank of Boston, as
Rights Agent, and of Section 203 of the Delaware Law inapplicable to the Offer,
the Merger and the Shareholder Agreements, and (D) recommend that the
shareholders of the Company accept the Offer and approve and adopt this
Agreement and the transactions, including, without limitation, the Merger,
contemplated hereby, and (ii) SG Cowen Securities Corporation ("SG Cowen") has
delivered to the Board an opinion to the effect that the consideration to be
received by the holders of Shares (other than Parent, Purchaser and their
affiliates) pursuant to each of the Offer and the Merger is fair to such holders
of Shares from a financial point of view, it being understood and acknowledged
that such opinion has been rendered to the Board and may only be relied upon by
the Board, the Company and any successors thereto. Subject only to the
provisions of Sections 6.04 and 8.01(e) below, the Company hereby consents to
the inclusion in the Offer Documents of the recommendation of the Board
described in the immediately preceding sentence; provided, however, that the
Board may withdraw such consent in the exercise of its fiduciary duties as
contemplated in Sections 6.04 and 8.01(e) below.

          (b)  As soon as reasonably practicable on the date of
commencement of the Offer, the Company shall file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with all
amendments and supplements thereto, the "Schedule 14D-9") containing, subject
only to the provisions of Sections 6.04 and 8.01(d) below, the recommendation of
the Board described in Section 1.02(a) and shall disseminate the Schedule 14D-9
to the extent required by Rule 14d-9 promulgated under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and any other applicable federal
securities laws. Each of the Company, Parent and Purchaser agree to correct
promptly any information provided by it for use in the Schedule 14D-9 which
shall have become false or misleading, and the Company further agrees to take
all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with
the SEC and disseminated to holders of Shares, in each case as and to the extent
required by applicable federal securities laws. Prior to the Company's filing of
the Schedule 14D-9, such Schedule shall have been provided to Purchaser and
Parent and shall not have been reasonably objected to.

          (c)  The Company shall promptly furnish Purchaser with mailing
labels containing the names and addresses of all record holders of Shares and
with security position listings of Shares held in stock depositories, each as of
a recent date, together with all other

                                       3
<PAGE>   9

available listings and computer files containing names, addresses and security
position listings of record holders and beneficial owners of Shares. The Company
shall furnish Purchaser with such additional information, including, without
limitation, updated listings and computer files of shareholders, mailing labels
and security position listings, and such other assistance as Parent, Purchaser
or their agents may reasonably request. Subject to the requirements of
applicable law, and except for such steps as are necessary to disseminate the
Offer Documents and any other documents necessary to consummate the Offer or the
Merger, Parent and Purchaser shall hold in confidence the information contained
in such labels, listings and files, shall use such information only in
connection with the Offer and the Merger and, if this Agreement shall be
terminated in accordance with Section 8.01, shall deliver to the Company, or
certify to the Company destruction of, all copies of such information then in
their possession.

          (d)  (i)  The Company will, promptly following the purchase and
payment for by Purchaser of all Shares validly tendered and not withdrawn
pursuant to the Offer, take all actions necessary to cause persons designated by
Parent to become directors of the Company so that the total number of persons so
designated equals that number of directors, rounded up to the next whole number,
which represents the product of (x) the total number of directors on the Board
of Directors of the Company multiplied by (y) the percentage that the number of
Shares so accepted for payment and paid for plus any Shares beneficially owned
by Parent, Purchaser or their respective affiliates on the date when Parent so
accepts for payment and pays for any Shares pursuant to the Offer bears to the
number of Shares outstanding at the time of such acceptance for payment and
payment. In furtherance thereof, the Company will increase the size of its Board
of Directors, or use best efforts to secure the resignation of directors, or
both, as is necessary to permit Parent's designees to be elected to the
Company's Board of Directors; provided, however, prior to the Effective Time (as
defined in Section 2.2), subject to the provisions of Section 1.02(d)(ii), the
Company's Board of Directors shall always have at least two members who are
directors of the Company as of the date hereof (the "Continuing Directors"). At
such time, the Company, if so requested, will cause persons designated by Parent
to constitute at least the same percentage of each committee of the Company's
Board of Directors as determined above in this Section 1.02(d)(i). The Company's
obligations to appoint designees to its Board of Directors shall be subject to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The
Company shall promptly take all actions required pursuant to such section and
rule in order to fulfill its obligations under this Section 1.02(d)(i). Parent
and Purchaser will supply the Company with all information which the Company
shall reasonably request with respect to nominees to the Company's Board of
Directors in order for the Company to make the filing required by Section 14(f)
of the Exchange Act. Except with respect to the information provided by Parent
or Purchaser pursuant to the immediately preceding sentence, the Company agrees
that none of the information attached to the Offer Documents pursuant to Section
14(f) or Rule 14f-1 shall contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements contained therein, in light of the circumstances in which they were
made, not misleading.

               (ii) Following the election or  appointment  of the designees of
Parent pursuant to Section 1.02(d)(i) and prior to the Effective Time, any
amendment or termination of this Agreement, extension for the performance of the
obligations or other acts of Parent and

                                       4
<PAGE>   10

Purchaser under this Agreement, waiver of the rights of the Company under this
Agreement, or action taken by the Company pursuant to, or that is described in,
Article 8 and Sections 1.01(a), 6.06, 8.04 and 8.05, notwithstanding anything
herein to the contrary, will (if and to the extent that there are any then
serving Continuing Directors) require the approval of a majority of the
Continuing Directors. If, prior to the Effective Time, the number of Continuing
Directors is fewer than two, the remaining Continuing Director, if any, will be
entitled to appoint a director to fill the vacancy created and such appointee
will be a Continuing Director for the purpose of this Agreement. The Continuing
Directors may not be removed prior to the Effective Time except for cause.


                                   ARTICLE II

                                   THE MERGER

          SECTION 2.01.  The Merger. Upon the terms and subject to the
conditions set forth in Article VII, and in accordance with Delaware Law, at the
Effective Time (as hereinafter defined), Purchaser shall be merged with and into
the Company. As a result of the Merger, the separate corporate existence of
Purchaser shall cease and the Company shall continue as the surviving
corporation of the Merger (the "Surviving Corporation"), and shall continue to
be governed by the laws of the State of Delaware.

          SECTION 2.02.  Effective Time; Closing. As promptly as
practicable after the satisfaction or, if permissible, waiver of the conditions
set forth in Article VII, the parties hereto shall cause the Merger to be
consummated by filing a certificate of merger in substantially the form of
Exhibit A hereto, or in such other form as the parties shall otherwise agree
(the "Certificate of Merger"), with the Delaware Secretary of State, in such
form as is required by, and executed in accordance with the relevant provisions
of, Delaware Law (the date and time of such filings being, collectively, the
"Effective Time"). Prior to such filing, a closing shall be held at the offices
of Honigman Miller Schwartz and Cohn, 2290 First National Building, Detroit,
Michigan 48226, or such other place as the parties shall agree, for the purpose
of confirming the satisfaction or waiver, as the case may be, of the conditions
set forth in Article VII.

          SECTION 2.03.  Effect of the Merger. At the Effective Time, the
effect of the Merger shall be as provided in the applicable provisions of
Delaware Law. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time, all the property, rights, privileges, powers and
franchises of the Company and Purchaser shall vest in the Surviving Corporation,
and all debts, liabilities, obligations, restrictions, disabilities and duties
of the Company and Purchaser shall become the debts, liabilities, obligations,
restrictions, disabilities and duties of the Surviving Corporation.

          SECTION 2.04.  Articles  of  Incorporation;   Bylaws.  (a)  The
Articles of Incorporation of Purchaser, as in effect immediately prior to the
Effective Time, shall be the Articles of Incorporation of the Surviving
Corporation until thereafter amended as provided by


                                       5
<PAGE>   11

applicable law and such Articles of Incorporation; provided, however, that, at
the Effective Time, Article I of the Articles of Incorporation of the Surviving
Corporation shall be amended to read as follows: "The name of the corporation is
Smartflex Systems, Inc. "

          (b)  The Bylaws of Purchaser, as in effect immediately prior to
the Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended as provided by law, the Articles of Incorporation of the
Surviving Corporation and such Bylaws.

          SECTION 2.05.  Directors and Officers. The directors of
Purchaser immediately prior to the Effective Time shall be the initial directors
of the Surviving Corporation, each to hold office in accordance with the
Articles of Incorporation and Bylaws of the Surviving Corporation, and the
officers of Purchaser immediately prior to the Effective Time shall be the
initial officers of the Surviving Corporation, in each case until their
respective successors are duly elected or appointed and qualified.

          SECTION 2.06.  Conversion  of  Securities.  At the  Effective  Time,
by virtue of the Merger and without any action on the part of Purchaser, the
Company or the holders of any of the Shares:

          (a)  Each Share issued and outstanding immediately prior to the
     Effective Time (other than any Shares to be cancelled pursuant to Section
     2.06(b)) shall be cancelled and shall be converted automatically into the
     right to receive an amount equal to the Per Share Amount in cash (the
     "Merger Consideration"), payable, without interest, to the holder of such
     Share, upon surrender, in the manner provided in Section 2.08, of the
     certificate that formerly evidenced such Share;

          (b)  Each Share owned by Purchaser, Parent or any direct or
     indirect wholly owned subsidiary of Parent or of the Company immediately
     prior to the Effective Time shall be cancelled and retired without any
     conversion thereof and no payment or distribution shall be made with
     respect thereto; and

          (c)  Each share of common stock, without par value, of
     Purchaser issued and outstanding immediately prior to the Effective Time
     shall be converted into and exchanged for one validly issued, fully paid
     and nonassessable share of Common Stock, $.0025 par value per share, of the
     Surviving Corporation.

          SECTION 2.07.  Employee and Director Stock Options. In accordance with
the terms of the Company's 1993 Equity Incentive Plan, 1994 Equity Incentive
Plan, 1995 Equity Incentive Plan and Acquisition Stock Plan (the "Stock Option
Plans"), each outstanding option to purchase Shares granted under the Stock
Option Plans shall, immediately prior to the Effective Time, become exercisable
regardless of the vesting schedule contained in any stock option agreement or in
any of the Stock Option Plans. Each outstanding option to purchase Shares
granted under the Stock Option Plans or otherwise shall be cancelled at the
Effective Time. In the event that any unexercised option is cancelled by the
Company, each holder of a cancelled option shall be entitled to receive, at the
Effective Time or as soon as practicable thereafter, from

                                       6
<PAGE>   12

the Company, in consideration for the cancellation of such option, an amount in
cash equal to the product of (i) the number of Shares previously subject to such
option and (ii) the excess, if any, of the Merger Consideration over the
exercise price per Share previously subject to such option (the "Spread").

          SECTION 2.08.  Surrender of Shares; Stock Transfer Books. (a)
Prior to the Effective Time, Purchaser shall designate a bank or trust company
to act as agent (the "Paying Agent") for the holders of Shares in connection
with the Merger to receive the funds to which holders of Shares shall become
entitled pursuant to Section 2.06(a), and at the Effective Time Purchaser shall
deposit with such Paying Agent an amount sufficient to pay the aggregate Merger
Consideration. Such funds shall be invested by the Paying Agent as directed by
the Surviving Corporation, provided that such investments shall be in
obligations of or guaranteed by the United States of America or of any agency
thereof and backed by the full faith and credit of the United States of America
or in commercial paper obligations rated A-1 or P-1 or better by Moody's
Investors Service, Inc. or Standard & Poor's Corporation, respectively.

          (b)  Promptly after the Effective Time, the Surviving
Corporation shall cause to be mailed to each person who was, at the Effective
Time, a holder of record of Shares entitled to receive the Merger Consideration
pursuant to Section 2.06(a) a form of letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the certificates
evidencing such Shares (the "Certificates") shall pass, only upon proper
delivery of the Certificates to the Paying Agent) and instructions for use in
effecting the surrender of the Certificates pursuant to such letter of
transmittal. Upon surrender to the Paying Agent of a Certificate, together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, and such other documents as may be required
pursuant to such instructions, the holder of such Certificate shall be entitled
to receive in exchange therefor the Merger Consideration for each Share formerly
evidenced by such Certificate, and such Certificate shall then be cancelled. No
interest shall accrue or be paid on the Merger Consideration payable upon the
surrender of any Certificate for the benefit of the holder of such Certificate.
If payment of the Merger Consideration is to be made to a person other than the
person in whose name the surrendered Certificate is registered on the stock
transfer books of the Company, it shall be a condition of payment that the
Certificate so surrendered shall be endorsed properly or otherwise be in proper
form for transfer and that the person requesting such payment shall have paid
all transfer and other taxes required by reason of the payment of the Merger
Consideration to a person other than the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation that such taxes either have been paid or are not applicable. In the
event any certificate representing Shares shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such certificate to be lost, stolen or destroyed, the Paying Agent will issue in
exchange for such lost, stolen or destroyed certificate the Merger Consideration
deliverable in respect thereof as determined in accordance with this Article II;
provided, however, the person to whom the Merger Consideration is paid shall, as
a condition precedent to the payment thereof, give the Surviving Corporation a
bond in such sum as it may direct or otherwise indemnify the Surviving
Corporation in a manner satisfactory to it against any claim that may be made
against the

                                       7
<PAGE>   13

Surviving Corporation with respect to the certificate alleged to have been lost,
stolen or destroyed.

          (c)  At any time following the sixth month after the
Effective Time, the Surviving Corporation shall be entitled to require the
Paying Agent to deliver to it any funds which had been made available to the
Paying Agent and not disbursed to holders of Shares (including, without
limitation, all interest and other income received by the Paying Agent in
respect of all funds made available to it) and, thereafter, such holders shall
be entitled to look only to the Surviving Corporation (subject to abandoned
property, escheat and other similar laws) only as general creditors thereof with
respect to any Merger Consideration that may be payable upon due surrender of
the Certificates held by them. Notwithstanding the foregoing, neither the
Surviving Corporation nor the Paying Agent shall be liable to any holder of a
Share for any Merger Consideration delivered in respect of such Share to a
public official pursuant to any abandoned property, escheat or other similar
law.

          (d)  At the close of business on the day of the Effective
Time, the stock transfer books of the Company shall be closed and, thereafter,
there shall be no further registration of transfers of Shares on the records of
the Company. From and after the Effective Time, the holders of Shares
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to such Shares except as otherwise provided herein or by
applicable law.


                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby represents and warrants to Parent and Purchaser that:

          SECTION 3.01.  Organization and Qualification; Subsidiaries.
Each of the Company and each subsidiary of the Company (a "Subsidiary"), is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation and has the requisite power and
authority and all necessary governmental approvals to own, lease and operate its
properties and to carry on its business as it is now being conducted, except
where the failure to be so organized, existing or in good standing or to have
such power, authority and governmental approvals would not, individually or in
the aggregate, have a Material Adverse Effect (as defined below). The Company
and each Subsidiary is duly qualified or licensed as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character of
the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except for such failures to be
so qualified or licensed and in good standing that would not, individually or in
the aggregate, have a Material Adverse Effect. When used in connection with the
Company or any Subsidiary, the term "Material Adverse Effect" means any change
or changes, event(s), condition(s), development(s) or effect(s) that adversely
affects, or may be reasonably likely to adversely affect, individually or in the
aggregate, the business, operations, results of operations, properties,
condition, financial

condition, cash flows, assets or liabilities (including, without limitation,
contingent liabilities) of the Company and the Subsidiaries taken as a whole and
the value of the Shares, in any case, by an amount equal to at least $2,500,000;
provided, however, that a Material Adverse Effect shall not include any adverse
effect resulting from general economic conditions or conditions generally
affecting the contract manufacturing market. A true and complete list of all the
Subsidiaries, together with the jurisdiction of incorporation of each Subsidiary
and the percentage of the outstanding capital stock (calculated on a fully
diluted basis) of each Subsidiary owned by the Company, each other Subsidiary
and any third party, is set forth in Section 3.01 of the Disclosure Schedule,
which has been delivered prior to the date of this Agreement by the Company to
Parent (the "Disclosure Schedule"). Except as disclosed in such Section 3.01,
the Company does not directly or indirectly own any equity or similar interest
in, or any interest convertible into or exchangeable or exercisable for any
equity or similar interest in, any corporation, partnership, joint venture or
other business association or entity.

          SECTION 3.02.  Articles of Incorporation and Bylaws. The
Company has heretofore furnished to Parent a complete and correct copy of the
Articles of Incorporation and the Bylaws or equivalent organizational documents,
each as amended to date, of the Company and each Subsidiary. Such Articles of
Incorporation, Bylaws and equivalent organization documents are in full force
and effect. Neither the Company nor any Subsidiary is in violation of any
provision of its Articles of Incorporation, Bylaws or equivalent organizational
documents.

          SECTION 3.03.  Capitalization. The authorized capital stock of
the Company consists of 5,000,000 shares of preferred stock (none of which is
issued and outstanding) and 25,000,000 Shares. As of the date hereof, (i)
6,493,994 Shares are issued and outstanding, all of which are validly issued,
fully paid and nonassessable, (ii) no Shares are held by the Subsidiaries or in
the Company's treasury, and (iii) 994,502 Shares are reserved for issuance
pursuant to stock options granted pursuant to the Company's Stock Option Plans
or otherwise. Except as set forth in this Section 3.03 or Section 3.03 of the
Disclosure Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
capital stock of the Company or any Subsidiary or obligating the Company or any
Subsidiary to issue or sell any shares of capital stock of, or other equity
interests in, the Company or any Subsidiary (including, without limitation, any
securities which are convertible into or exchangeable for Shares of capital
stock of, or other equity interests in, the Company or any Subsidiaries). All
Shares subject to issuance as aforesaid, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
will be duly authorized, validly issued, fully paid and nonassessable. Except as
set forth in Section 3.03 of the Disclosure Schedule, there are no outstanding
contractual obligations of the Company or any Subsidiary to repurchase, redeem
or otherwise acquire any Shares or any capital stock of any Subsidiary or to
provide funds to, or make any investment (in the form of a loan, capital
contribution or otherwise) in, any Subsidiary or any other person. Each
outstanding share of capital stock of each Subsidiary is duly authorized,
validly issued, fully paid and nonassessable and, except as set forth in Section
3.03 of the Disclosure Schedule, is owned free and clear of all liens and
encumbrances.

          SECTION 3.04.  Authority Relative to this Agreement. Subject to
approval by the affirmative vote of the shareholders of the Company, the Company
has all necessary power and authority to execute and deliver this Agreement, to
perform its obligations hereunder and to consummate the transactions, including,
without limitation, the Merger, contemplated hereby (the "Transactions"). The
execution and delivery of this Agreement by the Company and the consummation by
the Company of the Transactions have been duly and validly authorized by all
necessary corporate action and no other corporate proceedings on the part of the
Company are necessary to authorize this Agreement or to consummate the
Transactions (other than, with respect to the Merger, the approval and adoption
of this Agreement by the affirmative vote of the holders of a majority of the
outstanding Shares as required by Delaware Law and the Company's Certificate of
Incorporation, and the filing and recordation of the Certificate of Merger as
required by Delaware Law). This Agreement has been duly and validly executed and
delivered by the Company and, assuming the due authorization, execution and
delivery by Parent and Purchaser, constitutes a legal, valid and binding
obligation of the Company.

          SECTION 3.05.  No Conflict; Required Filings and Consents.
Except as set forth in Section 3.05 of the Disclosure Schedule, (a) the
execution and delivery of this Agreement by the Company do not, and the
performance of this Agreement by the Company will not, (i) conflict with or
violate the Articles of Incorporation or Bylaws or equivalent organizational
documents of the Company or any Subsidiary, (ii) conflict with or violate any
law, rule, regulation, order, judgment or decree applicable to the Company or
any Subsidiary or by which any property or asset of the Company or any
Subsidiary is bound or subject or (iii) result in any breach of or constitute a
default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any right of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or other
encumbrance of any nature on any property or asset of the Company or any
Subsidiary pursuant to, any material note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any Subsidiary is a party or by which the Company or any
Subsidiary or any property or asset of the Company or any Subsidiary is bound or
subject. Any costs and expenses which occur or are reasonably likely to occur as
a result of the failure to obtain the consent of the other parties to the
contracts and agreements listed in Section 3.05 of the Disclosure Schedule prior
to the Effective Time shall be borne by the Company and its Subsidiaries and
shall be considered in determining whether a Material Adverse Effect has
occurred.

          (b)  The execution and delivery of this Agreement by the
Company do not, and the performance of this Agreement by the Company will not,
require any consent, approval, authorization or permit of, or filing with, or
notification to, any governmental or regulatory authority, domestic or foreign,
except (i) for applicable requirements, if any, of the Exchange Act, state
securities or "blue sky" laws ("Blue Sky Laws") and state takeover laws, the
premerger notification requirements of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, and the rules and regulations promulgated
thereunder (the "HSR Act") and the filing and recordation of the Certificate of
Merger as required by Delaware Law, and (ii) where failure to obtain such
consents, approvals, authorizations or permits, or to make such filings or
notifications, would not prevent or delay consummation of the Offer or the
Merger, or otherwise


                                       10

prevent the Company from performing its obligations under this Agreement, or
would not, individually or in the aggregate, have a Material Adverse Effect.

          SECTION 3.06.  Compliance. Except as set forth in Section 3.06
of the Disclosure Schedule, neither the Company nor any Subsidiary is, in any
material respect, in conflict with, or in default or violation of, (i) any law,
rule, regulation, order, judgment or decree applicable to the Company or any
Subsidiary or by which any property or asset of the Company or any Subsidiary is
bound or subject or (ii) any material note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any Subsidiary is a party or by which the Company or any
Subsidiary or any property or asset of the Company or any Subsidiary is bound or
subject.

          SECTION 3.07.  SEC Filings; Financial Statements. (a) The
Company has filed all forms, reports and documents required to be filed by it
with the SEC in the past three years, and has heretofore delivered to Parent, in
the form filed with the SEC, (i) its Annual Reports on Form 10-K for the fiscal
years ended December 31, 1996, 1997 and 1998, respectively, (ii) its Quarterly

relating to the Company's meetings of shareholders (whether annual or special)
held in the past three years and (iv) all other forms, reports and other
registration statements (other than Quarterly Reports on Form 10-Q not referred
to in clause (ii) above) filed by the Company with the SEC in the past three
years (the forms, reports and other documents referred to in clauses (i), (ii),
(iii) and (iv) above being referred to herein, collectively, as the "SEC
Reports"). The most recent SEC Report filed by the Company is its Quarterly
Report on Form 10-Q for the period ended March 31, 1999. The SEC Reports (i)
were prepared in accordance with the requirements of the Securities Act of 1933,
as amended (the "Securities Act"), and the Exchange Act, as the case may be, and
the rules and regulations promulgated thereunder and (ii) did not, at the time
they were filed, contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements made therein, in the light of the circumstances under which
they were made, not misleading. No Subsidiary is required to file any form,
report or other document with the SEC.

          (b)  Each of the consolidated financial statements (including, in
each case, any notes thereto) contained in the SEC Reports was prepared from the
books and records of the Company in accordance with generally accepted
accounting principles applied on a consistent basis ("GAAP") throughout the
periods indicated (except as may be indicated in the notes thereto and except,
in the case of unaudited statements, as may be permitted under the Exchange Act)
and each fairly presents the consolidated financial position, results of
operations and changes in shareholders' equity and cash flows of the Company and
the consolidated Subsidiaries as at the respective dates thereof and for the
respective periods indicated therein (subject, in the case of unaudited
financial statements, to normal year-end audit adjustments).

          (c)  Except as and to the extent set forth on the consolidated balance
sheet of the Company and the consolidated Subsidiaries as at December 31, 1998
including the notes thereto (the "1998 Balance Sheet"), or as reflected on the
consolidated balance sheet of the

                                       11

<PAGE>   17

Company and the consolidated Subsidiaries as at May 31, 1999 or in Section 3.07
of the Disclosure Schedule, neither the Company nor any Subsidiary has any
liability or obligation of any nature (whether accrued, absolute, contingent or
otherwise) which would be required to be reflected on a balance sheet, or in the
notes thereto, prepared in accordance with GAAP.

          SECTION 3.08.  Absence of Certain Changes or Events. Since
December 31, 1998, except as set forth in Section 3.08 of the Disclosure
Schedule or as contemplated by this Agreement or disclosed in any SEC Report
filed since December 31, 1998 and prior to the date of this Agreement, the
Company and the Subsidiaries have conducted their businesses only in the
ordinary course and in a manner consistent with past practice and, since
December 31, 1998, there has not been (i) any Material Adverse Effect with
respect to the Company, (ii) any damage, destruction or loss (whether or not
covered by insurance) with respect to any property or asset of the Company or
any Subsidiary and having, individually or in the aggregate, a Material Adverse
Effect with respect to the Company, (iii) any material change by the Company in
its accounting methods, principles or practices, with respect to the Company
(iv) any revaluation by the Company of any asset (including, without limitation,
any writing down of the value of inventory or writing off of notes or accounts
receivable), other than in the ordinary course of business consistent with past
practice, (v) any failure by the Company to revalue any asset in accordance with
GAAP consistent with past practice, (vi) any entry by the Company or any
Subsidiary into any commitment or transaction material to the Company and the
Subsidiaries taken as a whole, (vii) any declaration, setting aside or payment
of any dividend or distribution in respect of any capital stock of the Company
or any redemption, purchase or other acquisition of any of its securities,

bonus, insurance, severance, deferred compensation, pension, retirement, profit
sharing, stock option (including, without limitation, the granting of stock
options, stock appreciation rights, performance awards or restricted stock
awards), stock purchase or other employee benefit plan, or any other increase in
the compensation payable or to become payable to any officers or key employees
of the Company or any Subsidiary, except customary increases in compensation to
employees generally incurred in the ordinary course of business consistent with
past practice, (ix) any entering into, renewal, modification or extension of,
any material contract, arrangement or agreement with any affiliate of the
Company, or (x) any entering into, renewal, modification or extension of, any
contract, arrangement or agreement with any other party having, individually or
in the aggregate, a Material Adverse Effect with respect to the Company.

          SECTION 3.09.  Absence of Litigation. Except as set forth in
Section 3.09 of the Disclosure Schedule or as disclosed in the SEC Reports filed
prior to the date of this Agreement, there is no claim, action, proceeding or
investigation pending or, to the knowledge of the Company, threatened against
the Company or any Subsidiary, or any property or asset of the Company or any
Subsidiary, before any court, arbitrator or administrative, governmental or
regulatory authority or body, domestic or foreign, which (i) the amount in
controversy is or could reasonably be expected to be at least $50,000, (ii)
seeks to, or is reasonably likely to, delay or prevent the consummation of any
Transaction or (iii) which, if adversely determined against the Company would
limit, in any material respect, the Company's ability to conduct its business as
currently conducted. As of the date hereof, except as set forth in Section 3.09
of the Disclosure Schedule, neither the Company nor any Subsidiary nor any
property or asset of the Company or any Subsidiary is subject to any order,
writ, judgment, injunction, decree, determination or award. Except as set forth
in Section 3.09 of the Disclosure


                                       12

Schedule, the Company and each Subsidiary has notified its insurance companies,
in accordance with the terms and conditions of its insurance policies, of any
pending or, to the knowledge of the Company, threatened litigation, and no
insurance company has denied coverage, reserved its rights to deny coverage or
otherwise advised the Company or any of its Subsidiaries of any defenses
available to such insurance company to deny coverage for any such pending or, to
the knowledge of the Company, threatened litigation.

          SECTION 3.10.  Employee Benefit Plans. (a) Section 3.10 of the
Disclosure Schedule contains a true and complete list of (i) all employee
benefit plans (within the meaning of Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) and all bonus, stock option,
stock purchase, restricted stock, incentive, deferred compensation, retiree
medical or life insurance, supplemental retirement, severance or other benefit
plans, programs or arrangements, and all employment, termination, severance or
other contracts or agreements to which the Company or any Subsidiary is a party,
with respect to which the Company or any Subsidiary has any obligation or which
are maintained, contributed to or sponsored by the Company or any Subsidiary for
the benefit of any current or former employee, officer or director of the
Company or any Subsidiary and (ii) each employee benefit plan for which the
Company or any Subsidiary could incur liability under Title IV of ERISA, or in
respect of which the Company or any Subsidiary remains secondarily liable under
Section 4204 of ERISA (collectively, the "Plans"). Except as set forth in
Section 3.10 of the Disclosure Schedule, no Plan is a "defined benefit plan"
within the meaning of Section 3(35) of ERISA and no Plan is subject to Title IV
of ERISA. Each Plan is in writing and the Company has previously furnished
Parent with a true and complete copy of each Plan and a true and complete copy
of each material document prepared in connection with each such Plan, including,
without limitation, (i) a copy of each trust or other funding arrangement, (ii)
each summary plan description and summary of material modifications, (iii) the
most recently filed Internal Revenue Service ("IRS") Form 5500, (iv) the most
recently received IRS determination letter for each such Plan, and (v) the most
recently prepared financial statement in connection with each such Plan. Except
as set forth in Section 3.10 of the Disclosure Schedule, neither the Company nor
any Subsidiary has any express or implied commitment (i) to create, incur
liability with respect to or cause to exist any other employee benefit plan,
program or arrangement, (ii) to enter into any contract or agreement to provide
compensation or benefits to any individual or (iii) to modify, change or
terminate any Plan, other than with respect to a modification, change or
termination required by ERISA or the Internal Revenue Code of 1986, as amended
(the "Code").

          (b)  Except as disclosed in Section 3.10 of the Disclosure
Schedule, none of the Plans (i) provides for the payment of separation,
severance, termination or similar-type benefits to any person, (ii) obligates
the Company or any Subsidiary to pay separation, severance, termination or other
benefits as a result of any Transaction or (iii) obligates the Company or any
Subsidiary to make any payment or provide any benefit that could be subject to a
tax under Section 4999 of the Code. Except as disclosed in Section 3.10 of the
Disclosure Schedule, none of the Plans provides for or promises retiree medical,
disability or life insurance

                                       13
<PAGE>   19

benefits to any current or former employee, officer or director of the Company
or any Subsidiary.

          (c)  Except as set forth in Section 3.10 of the Disclosure
Schedule, each Plan which is intended to be qualified under Section 401(a) or
401(k) of the Code has received a favorable determination letter from the IRS
that such Plan is so qualified, and each trust established in connection with
any Plan which is intended to be exempt from federal income taxation under
Section 501(a) of the Code has received a determination letter from the IRS that
such trust is so exempt. To the knowledge of the Company, no fact or event has
occurred since the date of any such determination letter from the IRS that could
adversely affect the qualified status of any such Plan or the exempt status of
any such trust. Each trust maintained or contributed to by the Company or any
Subsidiary which is intended to be qualified as a voluntary employees'
beneficiary association exempt from federal income taxation under Sections
501(a) and 501(c)(9) of the Code has received a favorable determination letter
from the IRS that it is so qualified and so exempt, and, to the knowledge of the
Company, no fact or event has occurred since the date of such determination by
the IRS that could adversely affect such qualified or exempt status.

          (d)  There has been no prohibited transaction (within the
meaning of Section 406 of ERISA or Section 4975 of the Code) with respect to any
Plan. Neither the Company nor any Subsidiary is currently liable or has
previously incurred any liability for any tax or penalty arising under Section
4971, 4972, 4979, 4980 or 4980B of the Code or Section 502(c) of ERISA, and no
fact or event exists which could give rise to any such liability. Neither the
Company nor any Subsidiary has incurred any liability under, arising out of or
by operation of Title IV of ERISA, including, without limitation, any liability
in connection with (i) the termination or reorganization of any employee pension
benefit plan subject to Title IV of ERISA or (ii) the withdrawal from any
Multiemployer Plan or Multiple Employer Plan, and no fact or event exists which
could give rise to any such liability.

          (e)  To the knowledge of the Company, each Plan is now and
has been operated in all respects in accordance with the requirements of all
applicable laws, including, without limitation, ERISA and the Code, and the
Company and each Subsidiary have performed all obligations required to be
performed by them under, are not in any respect in default under or in violation
of, and have no knowledge of any default or violation by any party to, any Plan.
All contributions, premiums or payments required to be made with respect to any
Plan have been timely made ,are fully deductible for income tax purposes and no
such deduction previously claimed has been challenged by any government entity.
The 1998 Balance Sheet reflects an accrual of all amounts of employer
contributions and premiums accrued but unpaid with respect to the Plans.

          (f)  The Company and the Subsidiaries have not incurred
any liability under, and have complied in all material respects with, the Worker
Adjustment Retraining Notification Act and the regulations promulgated
thereunder ("WARN") and do not reasonably expect to incur any such liability as
a result of actions taken or not taken prior to the Effective Time. Section
3.10(f) of the Disclosure Schedule lists (i) all the employees terminated or
laid off by the


                                       14

<PAGE>   20

Company or any Subsidiary during the 90 days prior to the date hereof and (ii)
all the employees of the Company or any Subsidiary who have experienced a
reduction in hours of work of more than 50% during any month during the 90 days
prior to the date hereof and describes all notices given by the Company and the
Subsidiaries in connection with WARN. The Company will, by written notice to
Parent and Purchaser, update Section 3.10(f) of the Disclosure Schedule to
include any such terminations, layoffs and reductions in hours from the date
hereof through the Effective Time and will provide Parent and Purchaser with any
related information which they may reasonably request.

          SECTION 3.11.  Labor Matters. Except as set forth in Section
3.11 of the Disclosure Schedule, (i) there are no controversies pending or, to
the knowledge of the Company, threatened between the Company or any Subsidiary,
on the one hand, and any of their respective employees or former employees, on
the other hand; (ii) neither the Company nor any Subsidiary is a party to any
collective bargaining agreement or other labor union contract applicable to
persons employed by the Company or any Subsidiary, nor, to the knowledge of the
Company, are there any activities or proceedings of any labor union to organize
any such employees; (iii) neither the Company nor any Subsidiary has breached or
otherwise failed to comply with any provision of any such agreement or contract
and there are no grievances outstanding against the Company or any Subsidiary
under any such agreement or contract; (iv) there are no unfair labor practice
complaints pending or, to the knowledge of the Company, threatened against the
Company or any Subsidiary before the National Labor Relations Board or any
current union representation questions involving employees of the Company or any
Subsidiary; and (v) there is no strike, slowdown, work stoppage or lockout, or,
to the knowledge of the Company, threat thereof, by or with respect to any
employees of the Company or any Subsidiary. Section 3.11 of the Disclosure
Letter sets forth an accurate and complete list of all agreements or
arrangements with employees, consultants (excluding attorneys and investment
banking firms) and agents of the Company or any Subsidiary, including (without
limitation, employment, consulting, severance, stay-bonus, termination or other
agreements or arrangements) where the total compensation to any such employee,
consultant or agent under any such agreement or arrangement (or series of
related agreements or arrangements) exceeds $100,000 in any year.

          SECTION 3.12.  Offer Documents; Schedule 14D-9; Proxy
Statement. Neither the Schedule 14D-9 nor any information supplied by the
Company for inclusion in the Offer Documents shall, at the respective times the
Schedule 14D-9, the Offer Documents, or any amendments or supplements thereto
are filed with the SEC or are first published, sent or given to shareholders of
the Company, as the case may be, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in the light of the circumstances
under which they are made, not misleading. In the event that Purchaser has not
designated a majority of the members of the Board pursuant to the terms of
Section 1.02(d) above and a shareholder vote is required, neither the
information supplied by the Company for inclusion in the proxy statement to be
sent to the shareholders of the Company in connection with the Special
Shareholders' Meeting (as defined in Section 6.01 hereof), nor the information
statement to be sent to shareholders of the Company in connection with the

supplemented, being referred to herein as the "Proxy Statement") shall not, at
the date the Proxy Statement (or any amendment or supplement thereto) is first
mailed to shareholders of the Company, at the time of the Special Shareholders'
Meeting, if applicable and at the Effective Time, be false or misleading with
respect to any material fact, or omit to state any material fact required to be
stated therein or necessary in order to make the statements made therein, in the
light of the circumstances under which they are made, not misleading or
necessary to correct any statement in any earlier communication with respect to
the solicitation of proxies for the Special Shareholders' Meeting which shall
have become false or misleading. The Schedule 14D-9 and the Proxy Statement
shall comply in all material respects as to form with the requirements of the
Exchange Act and the rules and regulations thereunder. Notwithstanding the
foregoing, the Company makes no representation or warranty with respect to any
information which is supplied in writing by Parent or Purchaser or which is
excerpted from or derived from public sources other than the Company's public
filings with the SEC.

          SECTION 3.13.  Tangible Property; Real Property and Leases. (a)
The Company and the Subsidiaries have good and marketable title to all their

Schedule, and subject to (i) liens for taxes, assessments or governmental

Company or any Subsidiary is subject to any governmental decree or order to be

parcel of real property owned or leased by the Company or any Subsidiary and of
the leases and other documents described in the immediately preceding sentence,
and accurate and complete copies of each such lease and other documents have
been provided to the Parent.

          SECTION 3.14.  Trademarks, Patents and Copyrights. Except as
set forth in Section 3.14 of the Disclosure Schedule, the Company and the
Subsidiaries own or possess adequate licenses or other valid rights to use all
material patents, patent rights, trademarks, trademark rights, trade names,
trade dress, trade name rights, copyrights, servicemarks, trade secrets,
applications for trademarks and for servicemarks, mask works, know-how and other
proprietary rights and information (collectively, "Proprietary Rights") used or
held for use in connection with the business of the Company and the Subsidiaries
as conducted since June 30, 1997, as currently conducted or as contemplated to
be conducted, and the Company is unaware of any assertion or claim challenging
the validity of any of such Proprietary Rights. Except as set forth in Section
3.14 of the Disclosure Schedule, the conduct of the business of the Company and
the Subsidiaries did not, does not and will not conflict in any way with any
Proprietary Rights of any third party that, individually or in the aggregate,
would have a Material Adverse Effect with respect to the Company. Except as set
forth in Section 3.14 of the Disclosure Schedule, there are no infringements of
any Proprietary Rights owned by or licensed by or to the Company or any
Subsidiary. Except as set forth in Section 3.14 of the Disclosure Schedule,
neither the Company nor any Subsidiary has licensed or otherwise permitted the
use by any third party of any Proprietary Rights.

          SECTION 3.15.  Taxes. The Company and the Subsidiaries have
filed all federal, state, local and foreign tax returns and reports (as defined
below) required to be filed by them and have paid and discharged all taxes (as
defined below) that have become due as of the date hereof, other than such
payments as are being contested in good faith by appropriate proceedings and
other than such payments as to which adequate reserves are set forth on the 1998
Balance Sheet. Neither the IRS nor any other taxing authority or agency,
domestic or foreign, is now asserting or, to the knowledge of the Company,
threatening to assert against the Company or any Subsidiary any deficiency or
claim for additional taxes or interest thereon or penalties in connection
therewith. To the knowledge of the Company's management, no tax return or
taxable period of the Company is under examination by any taxing authority, and
Company has not received written notice of any pending audit by any taxing
authority. Except as set forth on Schedule 3.15 of the Disclosure Schedule, the
Company is not a party to any agreement or contract which would result in
payment of any "excess parachute payment" within the meaning of Section 280G of
the Code. The Company has not been and is not a United States real property
holding company (as defined in Section 897(c)(2) of the Code) during the
applicable period specified in Section 897(c)(1)(A)(ii) of the Code). Neither
the Company nor any Subsidiary has granted any waiver of any statute of
limitations with respect to, or any extension of a period for the assessment of,
any federal, state, county, municipal or foreign income tax which is currently
in effect. The accruals and reserves for taxes reflected in the 1998 Balance
Sheet are adequate to cover all taxes accruable through such date (including
interest and penalties, if any, thereon) in accordance with GAAP. Neither the
Company nor any Subsidiary has made an election under Section 341(f) of the Code
or agreed to have Section 341(f)(2) of the Code apply to any disposition of a
subsection (f) asset owned by the Company or any of the Subsidiaries. For

subdivision or agency thereof, including interest, penalties, additions to tax
or additional amounts thereto. For purposes of this Agreement, "tax return"
shall mean any report, return, declaration or other information required to be
supplied to a taxing authority in connection with taxes. The Transactions,
including the Offer and the Merger, will not cause any change in the taxes
payable by any Subsidiary of the Company.

Agreement, the following terms shall have the following meanings: (i) "Hazardous

Subsidiaries or any affiliate of either the Company or any Subsidiary, have been

contractually assumed any liability of any other person involving Hazardous
Substances or Environmental Laws. Any costs which occur or are reasonably likely
to occur relating to the matters reflected in Section 3.16 of the Disclosure
Schedule shall be borne by the Company and its Subsidiaries and, to the extent
such costs are in excess of $50,000, such excess shall be considered in
determining whether a Material Adverse Effect has occurred.

          SECTION 3.17.  Material Contracts. Each contract or agreement
to which the Company or any of the Subsidiaries is a party that is material to
the Company or any Subsidiary (a "Material Contract"), or that is between the

facts exists that, with notice or the passage of time, or both, would constitute

Company, any third party under such Material Contracts. The Company or the
applicable Subsidiary and, to the knowledge of the Company, any third party
thereto, has duly complied in all material respects with the provision of each
Material Contract to which it is a party. An accurate and complete list of each
Material Contract and each Affiliate Contract is set forth in Section 3.17 of
the Disclosure Schedule, and accurate and complete copies of each Material

arrangements made by or on behalf of the Company. The Company has heretofore
furnished to Parent a complete and correct copy of all agreements among the
Company or any of its Subsidiaries, on the one hand, and SG Cowen (the "Broker

Engagement") pursuant to which such firms would be entitled to any payment
relating to the Transactions.

computerized systems, manufacturing equipment and other systems owned or used by
the Company or any Subsidiary, or licensed by the Company or any Subsidiary, as

under the laws of the jurisdiction of its incorporation and has the requisite
power and authority and all necessary governmental approvals to own, lease and
operate its properties and to carry on its business as it is now being
conducted, except where the failure to be so organized, existing or in good
standing or to have such power, authority and governmental approvals would not,
individually or in the aggregate, have a material adverse effect on the business
or operations of Parent and Purchaser and their respective subsidiaries, taken
as a whole.

          SECTION 4.02.  Authority Relative to This Agreement. Each of
Parent and Purchaser has all necessary corporate power and authority to execute
and deliver this Agreement, to perform its obligations hereunder and to
consummate the Transactions. The execution and delivery of this Agreement by
Parent and Purchaser and the consummation by Parent and Purchaser of the
Transactions have been duly and validly authorized by all necessary corporate
action and no other corporate proceedings on the part of Parent or Purchaser are
necessary to authorize this Agreement or to consummate the Transactions (other
than with respect to the Merger, the filing and recordation of the Certificate
of Merger as required by Delaware Law). This Agreement has been duly and validly
executed and delivered by Parent and Purchaser and, assuming the due
authorization, execution and delivery by the Company, constitutes a legal, valid
and binding obligation of each of Parent and Purchaser enforceable against each
of Parent and Purchaser in accordance with its terms.

          SECTION 4.03.  No Conflict; Required Filings and Consents. (a)

rights of termination, amendment, acceleration or cancellation of, or result in
the creation of a lien or other encumbrance on any property or asset of Parent
or Purchaser pursuant to, any note, bond, mortgage, indenture,

                                       20

contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Parent or Purchaser is a party or by which Parent or
Purchaser or any property or asset of either of them is bound or subject.

          (b)  The execution and delivery of this Agreement by Parent and
Purchaser do not, and the performance of this Agreement by Parent and Purchaser
will not, require any consent, approval, authorization or permit of, or filing
with or notification to, any governmental or regulatory authority, domestic or
foreign, except (i) for applicable requirements, if any, of the Exchange Act,
Blue Sky Laws and state takeover laws, the HSR Act and filing and recordation of
the Certificate of Merger as required by Delaware Law and (ii) where failure to
obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, would not prevent or delay consummation of the Offer
or the Merger, or otherwise prevent Parent or Purchaser from performing their
respective obligations under this Agreement.

statements made therein, in the light of the circumstances under which they are
made, not misleading. The information supplied by Parent for inclusion in the
Proxy Statement and the information statement to be sent to the Company's
shareholders will not, on the date the Proxy Statement (or any amendment or
supplement thereto) is first mailed to shareholders of the Company, at the time
of the Special Shareholders' Meeting, if applicable, and at the Effective Time,
contain any statement which, at such time and in light of the circumstances
under which it is made, is false or misleading with respect to any material
fact, or omits to state any material fact required to be stated therein or
necessary in order to make the statements therein not false or misleading or
necessary to correct any statement in any earlier communication with respect to
the solicitation of proxies for the Special Shareholders' Meeting which shall
have become false or misleading. Notwithstanding the foregoing, Parent and
Purchaser make no representation or warranty with respect to any information
supplied by the Company or any of its representatives which is contained in any
of the foregoing documents or the Offer Documents. The Offer Documents shall
comply in all material respects as to form with the requirements of the Exchange
Act and the rules and regulations thereunder.

which is made in writing by such person and which, if consummated, would provide
consideration per Share to the shareholders of the Company in excess of the Per
Share Amount (a "Superior Proposal"), if, and only to the extent that, the Board
determines in good faith, based upon the advice of SG Cowen and the written
advice of Stradling Yocca Carlson & Rauth, that such action is required for the
Board to comply with its fiduciary duties to shareholders under Delaware Law.

          SECTION 6.05.  Employee Benefits Matters; Employment Agreements. For a
period of one year from the Effective Time, Parent shall, or shall cause the
Company or the Surviving Corporation to, maintain the Plans (other than the
Stock Option Plans, the Company's 1995 Employee Stock Purchase Plan and the
Company's 1999 Key Employees Stock Ownership Plan) which the Company maintains
for the benefit of, or which are open to, a majority of the employees of the
Company on the terms in effect on the date hereof, or such other plans,
arrangements or programs as will provide employees with benefits that in the
aggregate are substantially equivalent to those provided under the Plans (other
than the Stock Option Plans, the Company's 1995 Employee Stock Purchase Plan and
the Company's 1999 Key Employees Stock Ownership Plan) as in effect on the date
hereof. In addition, Parent shall, or shall cause the Surviving Corporation to,
assume and agree to perform those agreements and policies listed in Schedule
6.05 of the Disclosure Schedule in the same manner and to the same extent that
the Company is required to perform such agreements and policies as of the date
hereof, and Parent shall not, and shall cause the Surviving Corporation to not,
withdraw or modify the obligations of Parent or the Surviving Corporation
thereunder, as the case may be, without obtaining the prior consent of the other
party or parties thereto, or the current beneficiaries thereof.

          SECTION 6.06.  Directors' and Officers' Indemnification and Insurance.

          (a)  The Articles of Incorporation and Bylaws of the Surviving
Corporation shall contain provisions no less favorable with respect to
indemnification than are set forth in Article VII of the Bylaws of the Company,
which provisions shall not be amended, repealed or otherwise modified for a
period of six years from the Effective Time in any manner that would affect
adversely the rights thereunder of individuals who at the Effective Time were
directors, officers, employees, fiduciaries or agents of the Company, unless
such modification shall be required by law. Any determinations made pursuant to
Section 3 of Article VII of the Bylaws of the Company with respect to the
appropriateness of indemnification shall be made in good faith.

          (b)  The Company shall, to the extent permitted by Delaware Law,
indemnify and hold harmless, and, after the Effective Time, the Surviving
Corporation shall, to the extent permitted by Delaware Law, indemnify and hold
harmless, each present and former director, officer, employee, fiduciary and
agent of the Company and each Subsidiary (collectively, the "Indemnified
Parties") against all costs and expenses (including reasonable attorneys' fees),
judgments, fines, losses, claims, damages, liabilities and settlement amounts
paid in connection with any claim, action, suit, proceeding or investigation
(whether arising before or after the Effective Time), whether civil, criminal,
administrative or investigative, arising out of or pertaining to any action or
omission in their capacity as an officer, director, employee, fiduciary or
agent, whether occurring before or after the Effective Time, for a period of six
years after the date hereof. In the event of any such claim, action, suit,
proceeding or investigation, (i) the Company or the Surviving Corporation, as
the case may be, shall pay the reasonable fees and expenses of counsel selected
by the Indemnified Parties, which counsel shall be reasonably satisfactory to
the Company or the Surviving Corporation, promptly after statements therefor are
received and (ii) the Company and the Surviving Corporation shall cooperate in
the defense of any such matter; provided, however, that neither the Company nor
the Surviving Corporation shall be liable for any settlement effected without
its written consent (which consent shall not be

                                       26
<PAGE>   32
unreasonably withheld); provided further that neither the Company nor the
Surviving Corporation shall be obligated pursuant to this Section 6.06(b) to pay
the fees and expenses of more than one counsel for all Indemnified Parties in
any single action except to the extent that two or more of such Indemnified
Parties shall have conflicting interests in the outcome of such action; and
provided further that, in the event that any claim for indemnification is
asserted or made within such six-year period, all rights to indemnification in
respect of such claim shall continue until the disposition of such claim.

          (c)  Prior to the Effective Time the Company shall, and
after the Effective Time the Surviving Corporation shall, make reasonable
advances to the Indemnified Parties to cover expenses for which such Indemnified
Parties would otherwise be entitled to indemnification pursuant to this Section
6.06, subject to receipt of an undertaking by the Indemnified Parties to
reimburse the Company for all such amounts advanced if it is subsequently
determined that the Company is not required to indemnify such Indemnified Party.

          (d)  The Surviving Corporation shall use its best efforts
to maintain in effect for six years from the Effective Time, if available, the
current directors' and officers' liability insurance policies maintained by the
Company (provided that the Surviving Corporation may substitute therefor
policies of at least the same coverage containing terms and conditions which are
not materially less favorable) with respect to matters occurring on or prior to
the Effective Time; provided, however, that in no event shall the Surviving
Corporation be required to expend pursuant to this Section 6.06(d) more than an
amount per year equal to 150% of current annual premiums paid by the Company for
such insurance, which amount shall be increased by 5% for each year hereafter.

          (e)  In the event the Company or the Surviving Corporation
or any of their respective successors or assigns (i) consolidates with or merges
into any other person and shall not be the continuing or surviving corporation
or entity of such consolidation or merger or (ii) transfers all or substantially
all of its properties and assets to any person, then, and in each such case,
proper provision shall be made so that the successors and assigns of the Company
or the Surviving Corporation, as the case may be, or at Parent's option, Parent,
shall assume the obligations set forth in this Section 6.06.

          SECTION 6.07.  Notification of Certain Matters. The Company
shall give prompt notice to Parent, and Parent shall give prompt notice to the
Company, of (i) the occurrence, or non-occurrence, of any event the occurrence,
or non-occurrence, of which causes any representation or warranty contained in
this Agreement to be untrue or inaccurate in any material respect and (ii) any
failure of the Company, Parent or Purchaser, as the case may be, to comply with
or satisfy any material covenant, condition or agreement to be complied with or
satisfied by it hereunder.

          SECTION 6.08.  Further Action; Reasonable Best Efforts. Upon
the terms and subject to the conditions hereof (including, without limitation,
Section 6.04), each of the parties hereto shall (i) make promptly its respective
filings, and thereafter make any other required submissions, under the HSR Act
with respect to the Transactions and (ii) use its reasonable best

                                       27
<PAGE>   33
efforts to take, or cause to be taken, all appropriate action, and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the Transactions,
including, without limitation, using its reasonable best efforts to obtain all
licenses, permits (including, without limitation, environmental permits),
consents, approvals, authorizations, qualifications and orders of governmental
authorities and parties to contracts with the Company and the Subsidiaries as
are necessary for the consummation of the Transactions and to fulfill the
conditions to the Offer and the Merger. In case at any time after the Effective
Time any further action is necessary or desirable to carry out the purposes of
this Agreement, the proper officers and directors of each party to this
Agreement shall use their reasonable best efforts to take all such action.

          SECTION 6.09.  Public Announcements. Parent and the Company shall
consult with each other before issuing any press release or otherwise
making any public statements with respect to this Agreement or any Transaction
and shall not issue any such press release or make any such public statement
prior to such consultation, except as may be required by law or any listing
agreement with a national securities exchange or The Nasdaq Stock Market to
which Parent or the Company is a party.

          SECTION 6.10.  Confidentiality  Agreement.  Upon the  acceptance  for
payment of Shares pursuant to the Offer, the Confidentiality Agreement shall be
deemed to have terminated without further action by the parties thereto.

          SECTION 6.11   Financial Statements. As soon as they are made
available to senior management of the Company, the Company shall make available
to Parent copies of all internally generated monthly, quarterly and annual
financial statements, consisting of consolidated balance sheets, and statements
of income and of cash flows.

          SECTION 6.12   SEC Reports. The Company shall timely file all
quarterly, annual and other reports and information required to be filed by it
with the SEC under the Exchange Act for all periods through and including the
Effective Time and, promptly after making such filing, shall provide Parent with
an accurate and complete copy thereof. The delivery to Parent of copies of any
such reports and information shall constitute a representation and warranty by
the Company to Parent that such report or information was prepared in accordance
with the requirements of the Exchange Act and did not, at the time it was filed,
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements made
therein, in light of the circumstances in which they were made, not misleading.

          SECTION 6.13   Customer Calls. The Company shall, and shall
cause each of its Subsidiaries and the officers, directors, employees and agents
of the Company and its Subsidiaries to, participate with Parent in visiting and
communicating with customers of the Company and its Subsidiaries, as reasonably
requested by Parent prior to the Effective Time.

                            CONDITIONS TO THE MERGER

          SECTION 7.01.  Conditions to the Merger. The respective obligations
of each party to effect the Merger shall be subject to the satisfaction at or
prior to the Effective Time of the following conditions:

          (a)  Shareholder Approval. This Agreement and the Transactions,

     including, without limitation, the Merger, shall have been approved and
     adopted by the affirmative vote of the shareholders of the Company (unless
     the vote of the shareholders is not required by Delaware Law);

          (b)  No Order. No foreign, United States or state governmental
     authority or other agency or commission or foreign, United States or state
     court of competent jurisdiction shall have enacted, issued, promulgated,
     enforced or entered any law, rule, regulation, executive order, decree,
     injunction or other order (whether temporary, preliminary or permanent)
     which is then in effect and has the effect of making the acquisition of
     Shares by Parent or Purchaser or any affiliate of either of them or the
     consummation of the Merger illegal or otherwise restricting, preventing or
     prohibiting consummation of the Transactions;

          (c)  Offer. Purchaser or its permitted assignee shall have
     purchased all Shares validly tendered and not withdrawn pursuant to the
     Offer; provided, however, that this condition shall only be applicable to
     the obligations of Parent or Purchaser if Purchaser's failure to purchase
     such Shares is not in breach of this Agreement or the terms of the Offer;
     and

          (d)  HSR Act and Foreign Antitrust Laws. Any waiting period
     (and any extension thereof) applicable to the consummation of the Merger
     under the HSR Act shall have expired or been terminated, and consummation
     of the Merger shall not result in a violation of any applicable material
     foreign antitrust or competition law, rule or regulation.


                                  ARTICLE VIII

                        TERMINATION, AMENDMENT AND WAIVER

          (a)  By mutual written consent duly authorized by the Boards of
     Directors of Parent, Purchaser and the Company; or

          (b)  By Parent, Purchaser or the Company if (i) the Effective
     Time shall not have occurred on or before December 31, 1999; provided,
     however, that the right to terminate this Agreement under this Section
     8.01(b) shall not be available to any party whose failure to fulfill any
     obligation under this Agreement has been the cause of, or resulted in, the
     failure of the Effective Time to occur on or before such date or (ii) any
     court of competent jurisdiction in the United States or other governmental
     authority shall have issued an order, decree, ruling or taken any other
     action restraining, enjoining or otherwise prohibiting the Offer or the
     Merger and such order, decree, ruling or other action shall have become
     final and nonappealable; or

          (c)  By Parent, upon approval of its Board of Directors, if (i)
     due to an occurrence or circumstance that would result in a failure to
     satisfy any condition set forth in Annex A hereto, Purchaser shall have (A)
     failed to commence the Offer within 60 days following the date of this
     Agreement, (B) terminated the Offer without having accepted any Shares for
     payment thereunder or (C) failed to pay for Shares pursuant to the Offer
     within 90 days following the commencement of the Offer; unless such action
     or inaction under (A), (B) or (C) shall have been caused by or resulted
     from the failure of Parent or Purchaser to perform in any material respect
     any covenant or agreement of either of them contained in this Agreement or
     the material breach by Parent or Purchaser of any representation or
     warranty of either of them contained in this Agreement or (ii) prior to the
     purchase of Shares pursuant to the Offer, the Board or any committee
     thereof shall have publicly withdrawn or modified in a manner adverse to
     Purchaser or Parent or, after receipt of a proposal involving a Competing
     Transaction, upon the request of Parent, shall not have, within four
     business days after receipt of Parent's request, publicly reaffirmed, its
     approval or recommendation of the Offer, this Agreement, the Merger, the
     Shareholder Agreements or any other Transaction, or shall have recommended
     another merger, consolidation, business combination, recapitalization,
     reorganization or similar transaction involving, or acquisition of, the
     Company or its assets, or another tender offer or exchange offer for
     Shares, or shall have resolved to do any of the foregoing; or

          (d)  By the Parent, upon approval of its Board of Directors, if
     the Company shall have materially breached its obligations under Section
     6.04 above; or

          (e)  By the Company, upon approval of the Board, if Parent or
     Purchaser shall materially breach any of its obligations hereunder and
     shall fail to cure such breach within ten days after written notice thereof
     from the Company or if due to an occurrence or circumstance that would
     result in a failure to satisfy any of the conditions set forth in Annex A
     hereto, Purchaser shall have (A) failed to commence the Offer within 60
     days following the date of this Agreement, (B) terminated the Offer without
     having accepted any Shares for payment thereunder or (C) failed to pay for
     Shares pursuant to the Offer within 90 days following the commencement of
     the Offer, unless such action or inaction under (A), (B), and (C) shall
     have been caused by or resulted from the failure of the

                                       30
<PAGE>   36

     Company to perform in any material respect any covenant or agreement of it
     contained in this Agreement or the material breach by the Company of any
     representation or warranty of it contained in this Agreement; or

          (f) by the Company or Parent, prior to the purchase of Shares pursuant
     to the Offer, if the Board, in full compliance with the provisions of
     Section 6.04 above, shall have approved the execution by the Company of a
     definitive agreement relating to a Superior Proposal.

          SECTION 8.02.  Effect of Termination. In the event of the termination
of this Agreement pursuant to Section 8.01, this Agreement shall forthwith
become void, and there shall be no liability on the part of any party hereto,
except as set forth in Sections 8.03 and 9.01, and nothing herein shall relieve
any party from liability for any breach hereof.

          SECTION 8.03.  Fees and Expenses.  (a) In the event that

          (i)  any person shall have commenced a tender or exchange offer
     for 25% or more (or which, assuming the maximum amount of securities which
     could be purchased, would result in any person beneficially owning 25% or
     more) of the then outstanding Shares or otherwise publicly announced a
     Competing Transaction for the direct or indirect acquisition of the Company
     or all or substantially all of its assets and (w) the Board does not
     recommend against the Competing Transaction, (x) the Offer shall have
     remained open for at least 20 business days, (y) the Minimum Condition
     shall not have been satisfied and (z) this Agreement shall have been
     terminated pursuant to Section 8.01; or

          (ii) this Agreement is terminated (x) pursuant to Section 8.01(c)(ii)
     or (y) pursuant to Section 8.01(d) or (z) pursuant to Section 8.01(f);

then, in any such event, the Company shall pay Parent promptly (but in no event
later than one business day after the first of such events shall have occurred)
a fee of U.S. $2,500,000 (the "Fee"), which amount shall be payable in
immediately available funds.

          (b)  Except as set forth above, all costs and expenses incurred in
connection with this Agreement and the Transactions shall be paid by the party
incurring such expenses, whether or not any Transaction is consummated.

          SECTION 8.04.  Amendment. This Agreement may be amended by the
parties hereto by action taken by or on behalf of their respective Boards of
Directors at any time prior to the Effective Time; provided, however, that,

which would reduce the amount or change the type of consideration into which
each Share shall be converted upon consummation of the Merger. This Agreement
may not be amended except by an instrument in writing signed by the parties
hereto.

other act of any other party hereto, (ii) waive any inaccuracy in the

binding upon and inure solely to the benefit of each party hereto, and nothing
in this Agreement, express or implied, is intended to or shall confer upon any
other person any right, benefit or remedy of any nature whatsoever under or by
reason of this Agreement, other than Section 6.06 (which is intended to be for
the benefit of the persons covered thereby and may be enforced by such persons).

                             Conditions to the Offer


          Notwithstanding any other provision of the Offer, Purchaser shall not
be required to accept for payment or pay for any Shares tendered pursuant to the
Offer, and may terminate or amend the Offer and may postpone the acceptance for
payment of and payment for Shares tendered, if (i) the Minimum Condition shall
not have been satisfied, (ii) any applicable waiting period under the HSR Act
shall not have expired or been terminated prior to the expiration of the Offer,
(iii) acceptance for payment of and payment for Shares tendered would result in
a violation of any applicable material foreign antitrust or competition law,
rule or regulation, or (iv) at any time on or after the date of this Agreement,
and prior to the acceptance for payment of Shares, any of the following
conditions shall exist:

          (a)  there shall have been entered any order, preliminary or
     permanent injunction, decree, judgment or ruling in any action or
     proceeding before any court or governmental, administrative or regulatory
     authority or agency, which makes illegal or otherwise directly or
     indirectly restrains or prohibits or makes materially more costly the
     making of the Offer, the acceptance for payment of, or payment for, any
     Shares by Parent, Purchaser or any other affiliate of Parent, or the
     consummation of any other Transaction;

          (b)  there shall have occurred any Material Adverse Effect with
     respect to the Company;

          (c)  (i)  the Board or any committee thereof (x) shall have
     publicly withdrawn or modified in a manner adverse to Parent or Purchaser
     the approval or recommendation of the Offer, the Merger, the Shareholder
     Agreements or the Agreement, (y) after the Company's receipt of a proposal
     involving a Competing Transaction, shall have failed to reaffirm such
     approval or recommendation upon request by Parent within four business days
     after the Company's receipt of Parent's request or (z) shall have approved
     or recommended any takeover proposal or any other acquisition of Shares
     other than the Offer and the Merger, or (ii) the Board or any committee
     thereof shall have resolved to do any of the foregoing;

          (d)  there shall have been any breach of warranty by, the
     Company in the Agreement as a result of which, individually or in the
     aggregate, there is, or may reasonably be expected to occur a Material
     Adverse Effect with respect to the Company;

          (e)  the Company shall have failed to perform in any material
     respect any obligation or to comply in any material respect with any
     material agreement or material covenant of the Company to be performed or
     complied with by it under the Agreement;


                                       37
<PAGE>   43

          (f)  the Agreement shall have been terminated in accordance with its
     terms; or

          (g)  Purchaser and the Company shall have agreed (i) that Purchaser
     shall terminate the Offer or (ii) that Purchaser shall postpone the
     acceptance for payment of or payment for Shares thereunder which, in the
     sole judgment of Purchaser, in any such case, and regardless of the
     circumstances (including any action or inaction by Parent or any of its
     affiliates) giving rise to any such condition, makes it inadvisable to
     proceed with such acceptance for payment or payment.

          The foregoing conditions are for the sole benefit of Purchaser and
Parent and may be asserted by Purchaser or Parent regardless of the
circumstances giving rise to any such condition or may be waived by Purchaser or
Parent in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent or Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right; the waiver
of any such right with respect to particular facts and other circumstances shall
not be deemed a waiver with respect to any other facts and circumstances; and
each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time.

                       STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among William L. Healey ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A. Concurrently herewith Saturn, Merger Sub and Smartflex Systems,
Inc., a Delaware corporation ("Smartflex"), are entering into an Agreement and
Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which
Merger Sub agrees to make a tender offer (the "Offer") for all of the
outstanding shares of common stock, $.0025 par value (the "Common Stock") of
Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B. Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 250,379 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C. As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D. Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

         THEREFORE, the parties agree as follows:

         1.  Agreement to Tender and Vote; Irrevocable Proxy.

             1.1 Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

             1.2 Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against

<PAGE>   2

         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

                  1.3. Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.       Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

                  2.1 Ownership of Shares. On the date hereof the Existing
Shares are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

                  2.2 Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of
Stockholder's obligations under this Agreement. The execution and delivery of
this Agreement by Stockholder will not violate any agreement, contract or
arrangement to which Stockholder is a party or is bound, including, without
limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

                                       2
<PAGE>   3

transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or regulation
applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

            2.3. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fees from Stockholder in connection with this Agreement
or the transactions contemplated hereby exclusive of any commission or finder's
fees referred to in the Merger Agreement.

         3. Representations and Warranties of Saturn and Merger Sub. Saturn and

            3.1 Authority. Each of Saturn and Merger Sub has full legal
right, power and authority to enter into and perform all of its obligations

constitutive documents of Saturn or Merger Sub, or any other agreement, contract
or arrangement to which Saturn or Merger Sub is a party or is bound. This
Agreement has been duly executed and delivered by each of Saturn and Merger Sub
and constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

            3.2. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fee from Saturn or Merger Sub in connection with this
Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4. Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger
Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5. Expenses. Except as provided in Section 19, each party hereto will
pay all of its expenses in connection with the transactions contemplated by this

and other advisers. The provisions of this Section 5 will survive the Closing
hereunder.

         6. Confidentiality. Stockholder recognizes that successful consummation
of the transactions contemplated by this Agreement may be dependent upon
confidentiality with respect to these matters. In this connection, pending
public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal




                                       3
<PAGE>   4

counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1 Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                      (a) sell, transfer, pledge, encumber, assign or otherwise
dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                      (b) grant any proxies, deposit any Shares into a voting
trust or enter into a voting agreement with respect to any Shares; or

                      (c) solicit, initiate or encourage the submission of any
proposal or offer from any person (other than Saturn or Merger Sub) relating to
any acquisition or purchase of all or any material portion of the assets of, or
any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

            7.2 Stockholder agrees, while this Agreement is in effect, to
notify Saturn promptly of the number of any shares of Common Stock beneficial
ownership of which is acquired by Stockholder after the date hereof.

         8. Legend and Stop Transfer Instructions. Immediately after the
execution of this Agreement (and from time to time prior to the termination of
this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

            THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
            EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN
            COMPLIANCE WITH THE TERMS AND CONDITIONS OF THE STOCK TENDER
            AND VOTING AGREEMENT AND ARE SUBJECT TO THE IRREVOCABLE PROXY
            REFERRED TO THEREIN, EACH DATED AS OF JULY 6, 1999, AS SUCH
            AGREEMENT MAY BE AMENDED FROM TIME TO TIME, AND COPIES OF
            WHICH ARE ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
            ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9. Survival of Representation and Warranties. Except as expressly set
forth herein, none of the representations, warranties, covenants and agreements
made by Stockholder, Saturn or Merger Sub in this Agreement will survive the
Closing hereunder.

        10. Notices. All notices or other communication required or permitted

         11. Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12. Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13. Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States

<PAGE>   7

District Court for the Central District of California and, in connection
therewith, each party to this Agreement hereby consents to the jurisdiction of
such courts and agrees that any service of process in connection with any
dispute arising out of this Agreement or the Merger may be given to any other
party hereto by certified mail, return receipt requested, at the respective
addresses set forth in Section 10 above.

         14. Injunctive Relief. The parties agree that in the event of a breach
of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15. Counterparts; Facsimile Signatures. This Agreement may be executed
in any number of counterparts (including by facsimile signature), each of which
will be deemed to be an original and all of which together will constitute one
and the same document.

         16. Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17. Further Assurances. Each party hereto will execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18. Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

         19. Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20. Amendment and Modification. This Agreement may be amended, modified
and supplemented only by a written document executed by Saturn, Merger Sub and
Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among William E. Bendush ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A.  Concurrently herewith Saturn, Merger Sub and Smartflex Systems,
Inc., a Delaware corporation ("Smartflex"), are entering into an Agreement and
Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which
Merger Sub agrees to make a tender offer (the "Offer") for all of the
outstanding shares of common stock, $.0025 par value (the "Common Stock") of
Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B.   Stockholder beneficially owns (as defined in Rule 13d-3
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")), as of the date hereof, 17,875 shares of Common Stock (the "Existing
Shares", together with any shares of Common Stock beneficial ownership of which
is acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C.  As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D.  Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

         THEREFORE, the parties agree as follows:

         1.  Agreement to Tender and Vote; Irrevocable Proxy.

             1.1   Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

             1.2   Voting. Stockholder hereby agrees that, during the time this
         Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against





<PAGE>   2




         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

             1.3.  Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.  Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

             2.1   Ownership of Shares. On the date hereof the Existing Shares
are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

             2.2   Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of

limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or regulation
applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

             2.3.  Finder's Fees. No person is, or will be, entitled to any

or the transactions contemplated hereby exclusive of any commission or finder's

Agreement has been duly executed and delivered by each of Saturn and Merger Sub
and constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

             3.2.  Finder's Fees. No person is, or will be, entitled to any

Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4.  Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger
Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5.  Expenses. Except as provided in Section 19, each party hereto will

         6.  Confidentiality. Stockholder recognizes that successful
consummation of the transactions contemplated by this Agreement may be dependent
upon confidentiality with respect to these matters. In this connection, pending
public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal

Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1   Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                        (a)   sell, transfer, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                        (b)   grant any proxies, deposit any Shares into a
voting trust or enter into a voting agreement with respect to any Shares; or

                        (c)   solicit, initiate or encourage the submission of
any proposal or offer from any person (other than Saturn or Merger Sub) relating
to any acquisition or purchase of all or any material portion of the assets of,
or any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

           8.     Legend and Stop Transfer Instructions. Immediately after the

this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
                  EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN
                  COMPLIANCE WITH THE TERMS AND CONDITIONS OF THE STOCK TENDER
                  AND VOTING AGREEMENT AND ARE SUBJECT TO THE IRREVOCABLE PROXY
                  REFERRED TO THEREIN, EACH DATED AS OF JULY 6, 1999, AS SUCH

                  WHICH ARE ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
                  ISSUER.

Immediately after the execution of this Agreement (and from time to time prior

         11.   Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12.   Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13.   Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States





                                       6

<PAGE>   7


District Court for the Central District of California and, in connection
therewith, each party to this Agreement hereby consents to the jurisdiction of
such courts and agrees that any service of process in connection with any
dispute arising out of this Agreement or the Merger may be given to any other
party hereto by certified mail, return receipt requested, at the respective
addresses set forth in Section 10 above.

         14.   Injunctive Relief. The parties agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15.   Counterparts; Facsimile Signatures. This Agreement may be
executed in any number of counterparts (including by facsimile signature), each
of which will be deemed to be an original and all of which together will
constitute one and the same document.

         16.   Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17.   Further Assurances. Each party hereto will execute and deliver
such additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18.   Third Party Beneficiaries. Nothing in this Agreement, expressed
or implied, will be construed to give any person other than the parties hereto
any legal or equitable right, remedy or claim under or by reason of this
Agreement or any provision contained herein.

         19.   Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20.   Amendment and Modification. This Agreement may be amended,
modified and supplemented only by a written document executed by Saturn, Merger
Sub and Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).





                                       9

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


     STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July 6,
1999 by and among Alan V. King ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

     A.   Concurrently herewith Saturn, Merger Sub and Smartflex Systems, Inc.,
a Delaware corporation ("Smartflex"), are entering into an Agreement and Plan of
Merger of even date herewith (the "Merger Agreement"), pursuant to which Merger
Sub agrees to make a tender offer (the "Offer") for all of the outstanding
shares of common stock, $.0025 par value (the "Common Stock") of Smartflex, at a
price of $10.50 per share (the "Offer Price"), in cash, following which
Smartflex will be merged with and into Merger Sub, with Smartflex as the
Surviving Corporation (the "Merger").

     B.   Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 21,875 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

     C.   As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

     D.   Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

     THEREFORE, the parties agree as follows:

     1.   Agreement to Tender and Vote; Irrevocable Proxy.

          1.1  Tender. Stockholder agrees to validly tender all Shares
     beneficially owned by it pursuant to the Offer within ten business days of
     commencement of the Offer, and not withdraw any such Shares, except to the
     extent that the tender of shares (including Shares acquired after the date
     hereof) pursuant to the Offer would subject Stockholder to liability under
     Section 16(b) of the Exchange Act.

          1.2  Voting. Stockholder hereby agrees that, during the time this
     Agreement is in effect, at any meeting of the stockholders of Smartflex,
     however called, and in any action by consent of the stockholders of
     Smartflex, Stockholder will: (a) vote all Shares beneficially owned by it
     in favor of the Merger; (b) vote all Shares beneficially owned by it
     against any action or agreement that would result in a breach of any
     covenant or any representation or warranty or any other obligation or
     agreement of Smartflex under or pursuant to the Merger Agreement; (c) vote
     all Shares beneficially owned by it against
<PAGE>   2

     any action or agreement that would impede, interfere with, delay, postpone
     or attempt to discourage, the Merger or the Offer including, but not
     limited to, (i) any corporate transaction not entered into in the ordinary
     course of business (other than the Merger), including, but not limited to,
     a merger, other business combination, reorganization, consolidation,
     recapitalization, dissolution or liquidation involving Smartflex, (ii) a
     sale or transfer of a material amount of assets of Smartflex or any of its
     subsidiaries, (iii) any change in the board of directors of Smartflex, (iv)
     any material change in the capitalization of Smartflex, (v) any change in
     the charter, by-laws or other organizational or constitutive documents of
     Smartflex, or (vi) any other material change in the corporate structure or
     business of Smartflex; and (d) without limiting the foregoing, consult with
     Saturn and vote all Shares beneficially owned by it in such manner as is
     determined by Saturn to be in compliance with the provisions of this
     Section 1.2. Stockholder acknowledges receipt and review of a copy of the
     Merger Agreement. Notwithstanding the foregoing, Stockholder may take any
     action in his or her role as a director or officer of Smartflex as
     permitted under Sections 6.04 and 8.01(e) of the Merger Agreement. This
     Agreement is intended to bind Stockholder only with respect to the specific
     matters set forth herein and shall not prohibit the Stockholder from acting
     in accordance with his or her fiduciary duties to Smartflex.

          1.3. Irrevocable Proxy. Contemporaneously with the execution of this
     Agreement: (i) Stockholder will deliver to Saturn a proxy in the form
     attached hereto as Exhibit A, which will be irrevocable to the fullest
     extent permitted by law (the "Proxy"), with respect to all Shares owned of
     record by Stockholder; and (ii) Stockholder will cause to be delivered to
     Saturn additional Proxies executed on behalf of each record owner of any
     Shares owned beneficially (but not owned of record) by Stockholder.

     2.   Representations and Warranties of Stockholder. Stockholder represents
and warrants to Saturn and Merger Sub as follows:

          2.1  Ownership of Shares. On the date hereof the Existing Shares are

transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing

applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

          2.3. Finder's Fees. No person is, or will be, entitled to any

enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions

respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

     11.  Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

     12.  Assigns. This Agreement will be binding upon and inure to the benefit
of the parties hereto and their respective successors, assigns and personal
representatives, but neither this Agreement nor any of the rights, interests or
obligations hereunder will be assigned by any of the parties hereto without the
prior written consent of the other parties, except that Merger Sub may assign
any or all of its rights and obligations hereunder to Saturn or any direct or
indirect wholly-owned subsidiary of Saturn without the consent of Stockholder or
Company, but no such transfer will relieve Merger Sub of its obligations under
this Agreement if such subsidiary does not perform the obligations of Merger Sub
hereunder.

     13.  Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States

                                       6
<PAGE>   7

District Court for the Central District of California and, in connection
therewith, each party to this Agreement hereby consents to the jurisdiction of
such courts and agrees that any service of process in connection with any
dispute arising out of this Agreement or the Merger may be given to any other
party hereto by certified mail, return receipt requested, at the respective
addresses set forth in Section 10 above.

     14.  Injunctive Relief. The parties agree that in the event of a breach of
any provision of this Agreement, the aggrieved party may be without an adequate
remedy at law. The parties therefore agree that in the event of a breach of any
provision of this Agreement, the aggrieved party will be entitled to obtain in
any court of competent jurisdiction a decree of specific performance or to
enjoin the continuing breach of such provision, in each case without the
requirement that a bond be posted, as well as to obtain damages for breach of
this Agreement. By seeking or obtaining such relief, the aggrieved party will
not be precluded from seeking or obtaining any other relief to which it may be
entitled.

     15.  Counterparts; Facsimile Signatures. This Agreement may be executed in
any number of counterparts (including by facsimile signature), each of which
will be deemed to be an original and all of which together will constitute one
and the same document.

     16.  Severability. Any term or provision of this Agreement which is invalid
or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

     17.  Further Assurances. Each party hereto will execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

     18.  Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

     19.  Legal Expenses. In the event any legal proceeding is commenced by any
party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

     20.  Amendment and Modification. This Agreement may be amended, modified
and supplemented only by a written document executed by Saturn, Merger Sub and
Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

     The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

     This proxy is irrevocable, is coupled with an interest and is granted in
connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

     The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Shares at any time until the earlier to occur of the
valid termination of the Merger Agreement pursuant to Section 8.01 thereof or
the Effective Time at any meeting of the stockholders of Smartflex, however
called, or in any written action by consent of stockholders of Smartflex: (a) in
favor of the Merger; (b) against any action or agreement that would result in a
breach of any covenant or any representation or warranty or any other obligation
or agreement of Smartflex under or pursuant to the Merger Agreement; or (c)
against any action or agreement that would impede, interfere with, delay,
postpone, or attempt to discourage the Merger or the Offer including, but not
limited to, (i) any corporate transaction not entered into in the ordinary
course of business (other than the Merger), including, but not limited to, a
merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

     This proxy will be binding upon the heirs, successors and assigns of the
undersigned (including any transferee of any of the Shares).

     Any term or provision of this proxy which is invalid or unenforceable, in
any jurisdiction will, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering invalid or unenforceable
the remaining terms and provisions of this proxy or affecting the validity or
enforceability of any of the terms or provisions of this proxy in any other
jurisdiction. If any provision of this proxy is so broad as to be unenforceable,
the provision will be interpreted to be only so broad as is enforceable.

     This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among William A. Klein ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A.  Concurrently herewith Saturn, Merger Sub and Smartflex Systems,
Inc., a Delaware corporation ("Smartflex"), are entering into an Agreement and
Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which
Merger Sub agrees to make a tender offer (the "Offer") for all of the
outstanding shares of common stock, $.0025 par value (the "Common Stock") of
Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B.  Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 15,875 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C.  As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D.  Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

         THEREFORE, the parties agree as follows:

         1.  Agreement to Tender and Vote; Irrevocable Proxy.

             1.1   Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

             1.2   Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against






<PAGE>   2



         any action or agreement that would result in a breach of any covenant
         or any representation or warranty or any other obligation or agreement
         of Smartflex under or pursuant to the Merger Agreement; (c) vote all
         Shares beneficially owned by it against any action or agreement that
         would impede, interfere with, delay, postpone or attempt to discourage,
         the Merger or the Offer including, but not limited to, (i) any
         corporate transaction not entered into in the ordinary course of
         business (other than the Merger), including, but not limited to, a
         merger, other business combination, reorganization, consolidation,
         recapitalization, dissolution or liquidation involving Smartflex, (ii)
         a sale or transfer of a material amount of assets of Smartflex or any
         of its subsidiaries, (iii) any change in the board of directors of
         Smartflex, (iv) any material change in the capitalization of Smartflex,
         (v) any change in the charter, by-laws or other organizational or
         constitutive documents of Smartflex, or (vi) any other material change
         in the corporate structure or business of Smartflex; and (d) without
         limiting the foregoing, consult with Saturn and vote all Shares
         beneficially owned by it in such manner as is determined by Saturn to
         be in compliance with the provisions of this Section 1.2. Stockholder
         acknowledges receipt and review of a copy of the Merger Agreement.
         Notwithstanding the foregoing, Stockholder may take any action in his
         or her role as a director or officer of Smartflex as permitted under
         Sections 6.04 and 8.01(e) of the Merger Agreement. This Agreement is
         intended to bind Stockholder only with respect to the specific matters
         set forth herein and shall not prohibit the Stockholder from acting in
         accordance with his or her fiduciary duties to Smartflex.

             1.3.  Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.  Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

             2.1   Ownership of Shares. On the date hereof the Existing Shares
are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

             2.2   Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of
Stockholder's obligations under this Agreement. The execution and delivery of
this Agreement by Stockholder will not violate any agreement, contract or
arrangement to which Stockholder is a party or is bound, including, without
limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the








                                       2

<PAGE>   3


transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or regulation
applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

             2.3.  Finder's Fees. No person is, or will be, entitled to any
commission or finder's fees from Stockholder in connection with this Agreement
or the transactions contemplated hereby exclusive of any commission or finder's

right, power and authority to enter into and perform all of its obligations
under this Agreement. The execution and delivery of this Agreement by Saturn and

constitutive documents of Saturn or Merger Sub, or any other agreement, contract
or arrangement to which Saturn or Merger Sub is a party or is bound. This
Agreement has been duly executed and delivered by each of Saturn and Merger Sub
and constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

             3.2.  Finder's Fees. No person is, or will be, entitled to any
commission or finder's fee from Saturn or Merger Sub in connection with this
Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4.  Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger

counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

         7.    Certain Covenants of Stockholder.

               7.1   Except in accordance with the provisions of this Agreement,
Stockholder agrees, while this Agreement is in effect, not to, directly or
indirectly:

                     (a)   sell, transfer, pledge, encumber, assign or otherwise
dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                     (b)   grant any proxies, deposit any Shares into a voting
trust or enter into a voting agreement with respect to any Shares; or

                     (c)   solicit, initiate or encourage the submission of any
proposal or offer from any person (other than Saturn or Merger Sub) relating to
any acquisition or purchase of all or any material portion of the assets of, or
any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

         8.    Legend and Stop Transfer Instructions. Immediately after the
execution of this Agreement (and from time to time prior to the termination of
this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

               THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
               EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN
               COMPLIANCE WITH THE TERMS AND CONDITIONS OF THE STOCK TENDER AND

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9.    Survival of Representation and Warranties. Except as expressly

         11.   Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12.   Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13.   Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States









                                       6
<PAGE>   7



District Court for the Central District of California and, in connection
therewith, each party to this Agreement hereby consents to the jurisdiction of
such courts and agrees that any service of process in connection with any
dispute arising out of this Agreement or the Merger may be given to any other
party hereto by certified mail, return receipt requested, at the respective
addresses set forth in Section 10 above.

         14.   Injunctive Relief. The parties agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15.   Counterparts; Facsimile Signatures. This Agreement may be
executed in any number of counterparts (including by facsimile signature), each
of which will be deemed to be an original and all of which together will
constitute one and the same document.

         16.   Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17.   Further Assurances. Each party hereto will execute and deliver
such additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18.   Third Party Beneficiaries. Nothing in this Agreement, expressed
or implied, will be construed to give any person other than the parties hereto
any legal or equitable right, remedy or claim under or by reason of this
Agreement or any provision contained herein.

         19.   Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20.   Amendment and Modification. This Agreement may be amended,
modified and supplemented only by a written document executed by Saturn, Merger
Sub and Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).





                                       9

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among Gary E. Liebl ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A.  Concurrently herewith Saturn, Merger Sub and Smartflex Systems,
Inc., a Delaware corporation ("Smartflex"), are entering into an Agreement and
Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which
Merger Sub agrees to make a tender offer (the "Offer") for all of the
outstanding shares of common stock, $.0025 par value (the "Common Stock") of
Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B.  Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 15,875 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C.  As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D.  Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

         THEREFORE, the parties agree as follows:

         1.  Agreement to Tender and Vote; Irrevocable Proxy.

             1.1    Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

             1.2    Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against








<PAGE>   2






         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

             1.3.   Irrevocable Proxy. Contemporaneously with the execution of
         this Agreement: (i) Stockholder will deliver to Saturn a proxy in the
         form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.  Representations and Warranties of Stockholder. Stockholder

         7.       Certain Covenants of Stockholder.

                  7.1   Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                        (a)    sell, transfer, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                        (b)    grant any proxies, deposit any Shares into a
voting trust or enter into a voting agreement with respect to any Shares; or

                        (c)    solicit, initiate or encourage the submission of
any proposal or offer from any person (other than Saturn or Merger Sub) relating
to any acquisition or purchase of all or any material portion of the assets of,
or any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

           8.     Legend and Stop Transfer Instructions. Immediately after the
execution of this Agreement (and from time to time prior to the termination of
this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
                  EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN
                  COMPLIANCE WITH THE TERMS AND CONDITIONS OF THE STOCK TENDER
                  AND VOTING AGREEMENT AND ARE SUBJECT TO THE IRREVOCABLE PROXY

                  WHICH ARE ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
                  ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

           9.     Survival of Representation and Warranties. Except as expressly
set forth herein, none of the representations, warranties, covenants and

         11.   Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12.   Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13.   Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States




                                       6


<PAGE>   7



District Court for the Central District of California and, in connection
therewith, each party to this Agreement hereby consents to the jurisdiction of
such courts and agrees that any service of process in connection with any
dispute arising out of this Agreement or the Merger may be given to any other
party hereto by certified mail, return receipt requested, at the respective
addresses set forth in Section 10 above.

         14.  Injunctive Relief. The parties agree that in the event of a breach
of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15.  Counterparts; Facsimile Signatures. This Agreement may be executed
in any number of counterparts (including by facsimile signature), each of which
will be deemed to be an original and all of which together will constitute one
and the same document.

         16.  Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17.  Further Assurances. Each party hereto will execute and deliver
such additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18.  Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

         19.  Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20.  Amendment and Modification. This Agreement may be amended,
modified and supplemented only by a written document executed by Saturn, Merger
Sub and Stockholder.

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

                   1.2 Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against

<PAGE>   2

         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

                  1.3. Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.       Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

                  2.1 Ownership of Shares. On the date hereof the Existing
Shares are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the

limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

                                       2
<PAGE>   3


transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or
regulation applicable to Stockholder, or (ii) any order, judgment or decree by
which Stockholder is bound.

            2.3. Finder's Fees. No person is, or will be, entitled to any

has been duly executed and delivered by each of Saturn and Merger Sub and
constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

            3.2. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fee from Saturn or Merger Sub in connection with this
Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4. Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger
Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5. Expenses. Except as provided in Section 19, each party hereto will
pay all of its expenses in connection with the transactions contemplated by this

and other advisers. The provisions of this Section 5 will survive the Closing
hereunder.

         6. Confidentiality. Stockholder recognizes that successful consummation
of the transactions contemplated by this Agreement may be dependent upon
confidentiality with respect to these matters. In this connection, pending
public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal

                                       3
<PAGE>   4



counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein
or in the Merger Agreement and except for filings required pursuant to the
Exchange Act, and the rules and regulations thereunder or disclosures
Stockholder's legal counsel advises in writing are necessary in order to
fulfill Stockholder's obligations imposed by law, in which event Stockholder
will give prompt prior notice of such disclosure to Saturn and cooperate with
Saturn in obtaining a protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1     Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                         (a) sell, transfer, pledge, encumber, assign or
otherwise  dispose of, or enter into any contract, option or other arrangement
or understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                         (b) grant any proxies, deposit any Shares into a voting
trust or enter into a voting agreement with respect to any Shares; or

                         (c) solicit,  initiate or encourage  the  submission of
any proposal or offer from any person (other than Saturn or Merger Sub) relating
to any acquisition or purchase of all or any material portion of the
assets of, or any equity interest in (other than pursuant to the exercise of
options outstanding on the date hereof), Smartflex or any subsidiary of
Smartflex, or any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary
of Smartflex (each a "Competing Transaction"), or participate in any
discussions or negotiations regarding, or furnish to any other person any
information with respect to, or otherwise, cooperate in any way with, or
assist or participate in, facilitate or encourage, any effort or attempt by
any person (other than Saturn and Merger Sub) to do or seek any of the
foregoing, Stockholder will cease and cause to be terminated any existing
activities, discussions or negotiations by or on its behalf with any person
(other than Saturn and Merger Sub) conducted heretofore with respect to
any Competing Transaction and will promptly notify Saturn following receipt of
any request by any person (other than Saturn or Merger Sub) relating to any
possible Competing Transaction or information concerning Smartflex. Nothing
contained herein will prohibit Stockholder, solely in his capacity as an
officer or as a member of the board of directors of Smartflex (the "Board"),
from furnishing information to, or entering into discussions or negotiations
with, any person (other than Saturn and Merger Sub) in connection with an
unsolicited proposal involving a fully-financed (as represented by such person)
Competing Transaction which is made in writing by such person (other than
Saturn and Merger Sub) and which, if consummated, would provide consideration
per share, of Common Stock to the stockholders of Smartflex in excess of the
Offer Price if, and only to the extent that, the Board determines in good
faith, based upon the advice of SG Cowen Securities Corporation and the
written advice of Stradling Yocca Carlson & Rauth, that such action is required
for the Board to comply with its fiduciary duties to stockholders under
Delaware law.

             7.2 Stockholder agrees, while this Agreement is in effect, to

ownership of which is acquired by Stockholder after the date hereof.

         8.  Legend and Stop Transfer Instructions. Immediately after the
execution of this Agreement (and from time to time prior to the termination of
this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

             THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
             EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN
             COMPLIANCE WITH THE TERMS AND CONDITIONS OF THE STOCK TENDER

             WHICH ARE ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
             ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9.  Survival of Representation and Warranties. Except as expressly set

         11. Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12. Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13. Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that

Agreement or the Merger may be given to any other party hereto by certified
mail, return receipt requested, at the respective addresses set forth in
Section 10 above.

         14. Injunctive Relief. The parties agree that in the event of a breach
of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15. Counterparts; Facsimile Signatures. This Agreement may be executed

and the same document.

         16. Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17. Further Assurances. Each party hereto will execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18. Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

         19. Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20. Amendment and Modification. This Agreement may be amended, modified
and supplemented only by a written document executed by Saturn, Merger Sub and
Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

                                       9
<PAGE>   10


         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among John W. Hohener ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A. Concurrently herewith Saturn, Merger Sub and Smartflex Systems,
Inc., a Delaware corporation ("Smartflex"), are entering into an Agreement and
Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which
Merger Sub agrees to make a tender offer (the "Offer") for all of the
outstanding shares of common stock, $.0025 par value (the "Common Stock") of
Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B. Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 57,113 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C. As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D. Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

         THEREFORE, the parties agree as follows:

         1. Agreement to Tender and Vote; Irrevocable Proxy.

            1.1 Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

            1.2 Voting. Stockholder hereby agrees that, during the time this
         Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against

<PAGE>   2

         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

                  1.3. Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.       Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

                  2.1 Ownership of Shares. On the date hereof the Existing
Shares are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned

additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

                  2.2 Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of

limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

                                       2
<PAGE>   3

transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or
regulation applicable to Stockholder, or (ii) any order, judgment or decree by
which Stockholder is bound.

            2.3. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fees from Stockholder in connection with this Agreement
or the transactions contemplated hereby exclusive of any commission or finder's
fees referred to in the Merger Agreement.

         3. Representations and Warranties of Saturn and Merger Sub. Saturn and

right, power and authority to enter into and perform all of its obligations

constitutive documents of Saturn or Merger Sub, or any other agreement, contract
or arrangement to which Saturn or Merger Sub is a party or is bound. This
Agreement has been duly executed and delivered by each of Saturn and Merger Sub
and constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

            3.2. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fee from Saturn or Merger Sub in connection with this
Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4. Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger
Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5. Expenses. Except as provided in Section 19, each party hereto will
pay all of its expenses in connection with the transactions contemplated by this

and other advisers. The provisions of this Section 5 will survive the Closing
hereunder.

         6. Confidentiality. Stockholder recognizes that successful consummation
of the transactions contemplated by this Agreement may be dependent upon
confidentiality with respect to these matters. In this connection, pending
public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal

                                       3
<PAGE>   4



counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein
or in the Merger Agreement and except for filings required pursuant to the
Exchange Act, and the rules and regulations thereunder or disclosures
Stockholder's legal counsel advises in writing are necessary in order to
fulfill  Stockholder's obligations imposed by law, in which event Stockholder
will give prompt prior notice of such disclosure to Saturn and cooperate with
Saturn in obtaining a protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1 Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                      (a) sell,  transfer,  pledge,  encumber, assign or
otherwise  dispose of, or enter into any contract, option or other  arrangement
or understanding with respect to the sale, transfer, pledge,  encumbrance,
assignment or other disposition of, any of the Shares;

                      (b) grant any proxies, deposit any Shares into a
voting trust or enter into a voting agreement with respect to any Shares; or

                      (c) solicit,  initiate or encourage  the
submission of any proposal or offer from any person (other than Saturn or
Merger Sub) relating to any acquisition or purchase of all or any material
portion of the assets of, or any equity interest in (other than pursuant to the
exercise of options outstanding on the date hereof), Smartflex or any
subsidiary of Smartflex, or any merger, consolidation, business combination,
reorganization, recapitalization or similar transaction involving Smartflex or
any subsidiary of Smartflex (each a "Competing Transaction"), or participate in
any discussions or negotiations regarding, or furnish to any other person any
information with respect to, or otherwise, cooperate in any way with, or assist
or participate in, facilitate or encourage, any effort or attempt by any person
 (other than Saturn and Merger Sub) to do or seek any of the foregoing,
Stockholder will cease and cause to be terminated any existing activities,
discussions or negotiations by or on its behalf with any person (other than
Saturn and Merger Sub) conducted heretofore with respect to any Competing
Transaction and will promptly notify Saturn following receipt of any request
by any person (other than Saturn or Merger Sub) relating to any possible
Competing Transaction or information concerning Smartflex. Nothing contained
herein will prohibit Stockholder, solely in his capacity as an officer or as a
member of the board of directors of Smartflex (the "Board"), from furnishing
information to, or entering into discussions or negotiations with, any person
(other than Saturn and Merger Sub) in connection with an unsolicited proposal
involving a fully-financed (as represented by such person) Competing
Transaction which is made in writing by such person (other than Saturn and
Merger Sub) and which, if consummated, would provide consideration per share, of
Common Stock to the stockholders of Smartflex in excess of the Offer Price if,
and only to the extent that, the Board determines in good faith, based upon the
advice of SG Cowen Securities Corporation and the written advice of Stradling
Yocca Carlson & Rauth, that such action is required for the Board to comply with
its fiduciary duties to stockholders under Delaware law.

            7.2 Stockholder agrees, while this Agreement is in effect, to
notify Saturn promptly of the number of any shares of Common Stock beneficial
ownership of which is acquired by Stockholder after the date hereof.

         8. Legend and Stop Transfer Instructions. Immediately after the
execution of this Agreement (and from time to time prior to the termination of
this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

            THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
            EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN
            COMPLIANCE WITH THE TERMS AND CONDITIONS OF THE STOCK TENDER
            AND VOTING AGREEMENT AND ARE SUBJECT TO THE IRREVOCABLE PROXY
            REFERRED TO THEREIN, EACH DATED AS OF JULY 6, 1999, AS SUCH

            ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9. Survival of Representation and Warranties. Except as expressly set
forth herein, none of the representations, warranties, covenants and agreements

         11. Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12. Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13. Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States
District Court for the Central District of California and, in connection
therewith, each party to

                                       6
<PAGE>   7




this Agreement hereby consents to the jurisdiction of such courts and agrees
that any service of process in connection with any dispute arising out of this
Agreement or the Merger may be given to any other party hereto by certified
mail, return receipt requested, at the respective addresses set forth in
Section 10 above.

         14. Injunctive Relief. The parties agree that in the event of a breach
of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15. Counterparts; Facsimile Signatures. This Agreement may be executed
in any number of counterparts (including by facsimile signature), each of which
will be deemed to be an original and all of which together will constitute one
and the same document.

         16. Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17. Further Assurances. Each party hereto will execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18. Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

         19. Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20. Amendment and Modification. This Agreement may be amended, modified
and supplemented only by a written document executed by Saturn, Merger Sub and
Stockholder.

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and

record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as

undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date

exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,

by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

     Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among Richard D. Bell ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A.       Concurrently herewith Saturn, Merger Sub and Smartflex
Systems, Inc., a Delaware corporation ("Smartflex"), are entering into an
Agreement and Plan of Merger of even date herewith (the "Merger Agreement"),
pursuant to which Merger Sub agrees to make a tender offer (the "Offer") for all
of the outstanding shares of common stock, $.0025 par value (the "Common Stock")
of Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B.       Stockholder beneficially owns (as defined in Rule 13d-3
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")), as of the date hereof, 75,649 shares of Common Stock (the "Existing
Shares", together with any shares of Common Stock beneficial ownership of which
is acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C.       As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D.       Saturn and Merger Sub have entered into the Merger Agreement
in reliance on Stockholder's representations, warranties, covenants and
agreement hereunder.

         THEREFORE, the parties agree as follows:

         1.       Agreement to Tender and Vote; Irrevocable Proxy.

                  1.1 Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

                   1.2 Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against


<PAGE>   2

         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

                  1.3. Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.       Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

                  2.1 Ownership of Shares. On the date hereof the Existing
Shares are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

                  2.2 Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of

limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

<PAGE>   3


transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or regulation
applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

                  2.3. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fees from Stockholder in connection with this Agreement
or the transactions contemplated hereby exclusive of any commission or finder's
fees referred to in the Merger Agreement.

Agreement has been duly executed and delivered by each of Saturn and Merger Sub
and constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

                  3.2. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fee from Saturn or Merger Sub in connection with this
Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4.       Termination. This Agreement (other than the provisions of
Sections 5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger
Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5.       Expenses. Except as provided in Section 19, each party hereto
will pay all of its expenses in connection with the transactions contemplated by

counsel and other advisers. The provisions of this Section 5 will survive the
Closing hereunder.

         6.       Confidentiality. Stockholder recognizes that successful
consummation of the transactions contemplated by this Agreement may be dependent
upon confidentiality with respect to these matters. In this connection, pending
public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal


                                       3
<PAGE>   4


counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1 Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                  (a) sell, transfer, pledge, encumber, assign or otherwise

dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                  (b) grant any proxies, deposit any Shares into a voting
trust or enter into a voting agreement with respect to any Shares; or

                  (c) solicit, initiate or encourage the submission of any
proposal or offer from any person (other than Saturn or Merger Sub) relating to
any acquisition or purchase of all or any material portion of the assets of, or
any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

this Agreement), Stockholder will cause Smartflex to provide for each

                  ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9.       Survival of Representation and Warranties. Except as expressly
set forth herein, none of the representations, warranties, covenants and
agreements made by Stockholder, Saturn or Merger Sub in this Agreement will
survive the Closing hereunder.

         11.      Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12.      Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13.      Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States
District Court for the Central District of California and, in connection
therewith, each party to


                                       6

<PAGE>   7

this Agreement hereby consents to the jurisdiction of such courts and agrees
that any service of process in connection with any dispute arising out of this
Agreement or the Merger may be given to any other party hereto by certified
mail, return receipt requested, at the respective addresses set forth in Section
10 above.

         14.      Injunctive Relief. The parties agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15.      Counterparts; Facsimile Signatures. This Agreement may be
executed in any number of counterparts (including by facsimile signature), each
of which will be deemed to be an original and all of which together will
constitute one and the same document.

         16.      Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17.      Further Assurances. Each party hereto will execute and deliver
such additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18.      Third Party Beneficiaries. Nothing in this Agreement,
expressed or implied, will be construed to give any person other than the
parties hereto any legal or equitable right, remedy or claim under or by reason
of this Agreement or any provision contained herein.

         19.      Legal Expenses. In the event any legal proceeding is commenced
by any party to this Agreement to enforce or recover damages for any breach of
the provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among James Cogan ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A.       Concurrently herewith Saturn, Merger Sub and Smartflex
Systems, Inc., a Delaware corporation ("Smartflex"), are entering into an
Agreement and Plan of Merger of even date herewith (the "Merger Agreement"),
pursuant to which Merger Sub agrees to make a tender offer (the "Offer") for all
of the outstanding shares of common stock, $.0025 par value (the "Common Stock")
of Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B.       Stockholder beneficially owns (as defined in Rule 13d-3
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")), as of the date hereof, no shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C.       As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D.       Saturn and Merger Sub have entered into the Merger Agreement
in reliance on Stockholder's representations, warranties, covenants and
agreement hereunder.

         THEREFORE, the parties agree as follows:

         1.       Agreement to Tender and Vote; Irrevocable Proxy.

                  1.1 Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

                   1.2 Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against

<PAGE>   2



         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

                  1.3. Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.       Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

                  2.1 Ownership of Shares. On the date hereof the Existing
Shares are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

                  2.2 Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of

Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation

applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

                  2.3. Finder's Fees. No person is, or will be, entitled to any
commission or finder's fees from Stockholder in connection with this Agreement
or the transactions contemplated hereby exclusive of any commission or finder's

and constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

                  3.2. Finder's Fees. No person is, or will be, entitled to any

Agreement or the transactions contemplated hereby exclusive of any commission or
finder's fees referred to in the Merger Agreement.

         4.       Termination. This Agreement (other than the provisions of
Sections 5, 6 and 19 which will survive any termination of this Agreement), will

Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5.       Expenses. Except as provided in Section 19, each party hereto

public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal

<PAGE>   4

counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1 Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                      (a)      sell, transfer, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                      (b)      grant any proxies, deposit any Shares into a
voting trust or enter into a voting agreement with respect to any Shares; or

                      (c)      solicit, initiate or encourage the submission of
any proposal or offer from any person (other than Saturn or Merger Sub) relating
to any acquisition or purchase of all or any material portion of the assets of,
or any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

                  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
                  EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN

                  ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9.       Survival of Representation and Warranties. Except as expressly
set forth herein, none of the representations, warranties, covenants and
agreements made by Stockholder, Saturn or Merger Sub in this Agreement will

         11.      Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12.      Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13.      Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States
District Court for the Central District of California and, in connection
therewith, each party to


                                       6

<PAGE>   7

this Agreement hereby consents to the jurisdiction of such courts and agrees
that any service of process in connection with any dispute arising out of this
Agreement or the Merger may be given to any other party hereto by certified
mail, return receipt requested, at the respective addresses set forth in Section
10 above.

         14.      Injunctive Relief. The parties agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15.      Counterparts; Facsimile Signatures. This Agreement may be
executed in any number of counterparts (including by facsimile signature), each
of which will be deemed to be an original and all of which together will
constitute one and the same document.

         16.      Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17.      Further Assurances. Each party hereto will execute and deliver
such additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18.      Third Party Beneficiaries. Nothing in this Agreement,
expressed or implied, will be construed to give any person other than the
parties hereto any legal or equitable right, remedy or claim under or by reason
of this Agreement or any provision contained herein.

         19.      Legal Expenses. In the event any legal proceeding is commenced
by any party to this Agreement to enforce or recover damages for any breach of
the provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20.      Amendment and Modification. This Agreement may be amended,
modified and supplemented only by a written document executed by Saturn, Merger
Sub and Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


         STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July
6, 1999 by and among Christopher Rollison ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

         A. Concurrently herewith Saturn, Merger Sub and Smartflex Systems,
Inc., a Delaware corporation ("Smartflex"), are entering into an Agreement and
Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which
Merger Sub agrees to make a tender offer (the "Offer") for all of the
outstanding shares of common stock, $.0025 par value (the "Common Stock") of
Smartflex, at a price of $10.50 per share (the "Offer Price"), in cash,
following which Smartflex will be merged with and into Merger Sub, with
Smartflex as the Surviving Corporation (the "Merger").

         B. Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 50,292 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

         C. As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

         D. Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

         THEREFORE, the parties agree as follows:

         1. Agreement to Tender and Vote; Irrevocable Proxy.

            1.1 Tender. Stockholder agrees to validly tender all Shares
         beneficially owned by it pursuant to the Offer within ten business days
         of commencement of the Offer, and not withdraw any such Shares, except
         to the extent that the tender of shares (including Shares acquired
         after the date hereof) pursuant to the Offer would subject Stockholder
         to liability under Section 16(b) of the Exchange Act.

            1.2 Voting. Stockholder hereby agrees that, during the time
         this Agreement is in effect, at any meeting of the stockholders of
         Smartflex, however called, and in any action by consent of the
         stockholders of Smartflex, Stockholder will: (a) vote all Shares
         beneficially owned by it in favor of the Merger; (b) vote all Shares
         beneficially owned by it against any action or agreement that would
         result in a breach of any covenant or any representation or warranty or
         any other obligation or agreement of Smartflex under or pursuant to the
         Merger Agreement; (c) vote all Shares beneficially owned by it against



<PAGE>   2

         any action or agreement that would impede, interfere with, delay,
         postpone or attempt to discourage, the Merger or the Offer including,
         but not limited to, (i) any corporate transaction not entered into in
         the ordinary course of business (other than the Merger), including, but
         not limited to, a merger, other business combination, reorganization,
         consolidation, recapitalization, dissolution or liquidation involving
         Smartflex, (ii) a sale or transfer of a material amount of assets of
         Smartflex or any of its subsidiaries, (iii) any change in the board of
         directors of Smartflex, (iv) any material change in the capitalization
         of Smartflex, (v) any change in the charter, by-laws or other
         organizational or constitutive documents of Smartflex, or (vi) any
         other material change in the corporate structure or business of
         Smartflex; and (d) without limiting the foregoing, consult with Saturn
         and vote all Shares beneficially owned by it in such manner as is
         determined by Saturn to be in compliance with the provisions of this
         Section 1.2. Stockholder acknowledges receipt and review of a copy of
         the Merger Agreement. Notwithstanding the foregoing, Stockholder may
         take any action in his or her role as a director or officer of
         Smartflex as permitted under Sections 6.04 and 8.01(e) of the Merger
         Agreement. This Agreement is intended to bind Stockholder only with
         respect to the specific matters set forth herein and shall not prohibit
         the Stockholder from acting in accordance with his or her fiduciary
         duties to Smartflex.

                  1.3. Irrevocable Proxy. Contemporaneously with the execution
         of this Agreement: (i) Stockholder will deliver to Saturn a proxy in
         the form attached hereto as Exhibit A, which will be irrevocable to the
         fullest extent permitted by law (the "Proxy"), with respect to all
         Shares owned of record by Stockholder; and (ii) Stockholder will cause
         to be delivered to Saturn additional Proxies executed on behalf of each
         record owner of any Shares owned beneficially (but not owned of record)
         by Stockholder.

         2.       Representations and Warranties of Stockholder. Stockholder
represents and warrants to Saturn and Merger Sub as follows:

                  2.1 Ownership of Shares. On the date hereof the Existing
Shares are all of the Shares currently beneficially owned by Stockholder. On the
Closing Date, the Shares will constitute all of the shares of Common Stock owned
beneficially by Stockholder. Stockholder does not have any rights to acquire any
additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting
agreements or voting trusts, and claims of every kind (other than the
encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

                  2.2 Power; Binding Agreement. Stockholder has the full legal
capacity, right, power and authority to enter into and perform all of

limitation, any voting agreement, stockholders agreement or voting trust. This
Agreement has been duly executed and delivered by Stockholder and constitutes a
legal, valid and binding agreement of Stockholder, enforceable in accordance
with its terms. Neither the execution or delivery of this Agreement nor the
consummation by Stockholder of the

transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation

applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

            2.3. Finder's Fees. No person is, or will be, entitled to any

enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,

applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

            3.2. Finder's Fees. No person is, or will be, entitled to any

finder's fees referred to in the Merger Agreement.

         4. Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts

Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

         5. Expenses. Except as provided in Section 19, each party hereto will

counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

         7.       Certain Covenants of Stockholder.

                  7.1 Except in accordance with the provisions of this
Agreement, Stockholder agrees, while this Agreement is in effect, not to,
directly or indirectly:

                      (a) sell, transfer, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

                      (b) grant any proxies, deposit any Shares into a
voting trust or enter into a voting agreement with respect to any Shares; or

                      (c) solicit, initiate or encourage the submission of
any proposal or offer from any person (other than Saturn or Merger Sub) relating
to any acquisition or purchase of all or any material portion of the assets of,
or any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

this Agreement), Stockholder will cause Smartflex to provide for each
certificate representing Shares beneficially owned by Stockholder to bear a
legend in the following form:

             THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
             EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN

             ISSUER.

Immediately after the execution of this Agreement (and from time to time prior
to the termination of this Agreement), Stockholder will cause Smartflex to
require the transfer agent for its Common Stock to make a notation in its
records prohibiting the transfer of any of the Shares, except in accordance with
the terms and conditions of this Agreement.

         9.  Survival of Representation and Warranties. Except as expressly set
forth herein, none of the representations, warranties, covenants and agreements
made by Stockholder, Saturn or Merger Sub in this Agreement will survive the
Closing hereunder.

         10. Notices. All notices or other communication required or permitted
hereunder will be in writing, will be given by hand delivery, U.S. Express Mail

         11. Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

         12. Assigns. This Agreement will be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns and
personal representatives, but neither this Agreement nor any of the rights,
interests or obligations hereunder will be assigned by any of the parties hereto
without the prior written consent of the other parties, except that Merger Sub
may assign any or all of its rights and obligations hereunder to Saturn or any
direct or indirect wholly-owned subsidiary of Saturn without the consent of
Stockholder or Company, but no such transfer will relieve Merger Sub of its
obligations under this Agreement if such subsidiary does not perform the
obligations of Merger Sub hereunder.

         13. Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States
District Court for the Central District of California and, in connection
therewith, each party to



                                       6

<PAGE>   7

this Agreement hereby consents to the jurisdiction of such courts and agrees
that any service of process in connection with any dispute arising out of this
Agreement or the Merger may be given to any other party hereto by certified
mail, return receipt requested, at the respective addresses set forth in Section
10 above.

         14. Injunctive Relief. The parties agree that in the event of a breach
of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party will be entitled
to obtain in any court of competent jurisdiction a decree of specific
performance or to enjoin the continuing breach of such provision, in each case
without the requirement that a bond be posted, as well as to obtain damages for
breach of this Agreement. By seeking or obtaining such relief, the aggrieved
party will not be precluded from seeking or obtaining any other relief to which
it may be entitled.

         15. Counterparts; Facsimile Signatures. This Agreement may be executed
in any number of counterparts (including by facsimile signature), each of which
will be deemed to be an original and all of which together will constitute one
and the same document.

         16. Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

         17. Further Assurances. Each party hereto will execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

         18. Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

         19. Legal Expenses. In the event any legal proceeding is commenced by
any party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

         20. Amendment and Modification. This Agreement may be amended, modified
and supplemented only by a written document executed by Saturn, Merger Sub and
Stockholder.

                            Form Of Irrevocable Proxy

         The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

         This proxy is irrevocable, is coupled with an interest and is granted
in connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

         The attorneys and proxies named above will be empowered, and may
exercise this proxy, to vote the Shares at any time until the earlier to occur
of the valid termination of the Merger Agreement pursuant to Section 8.01
thereof or the Effective Time at any meeting of the stockholders of Smartflex,
however called, or in any written action by consent of stockholders of
Smartflex: (a) in favor of the Merger; (b) against any action or agreement that
would result in a breach of any covenant or any representation or warranty or
any other obligation or agreement of Smartflex under or pursuant to the Merger
Agreement; or (c) against any action or agreement that would impede, interfere
with, delay, postpone, or attempt to discourage the Merger or the Offer
including, but not limited to, (i) any corporate transaction not entered into in
the ordinary course of business (other than the Merger), including, but not
limited to, a merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

         This proxy will be binding upon the heirs, successors and assigns of
the undersigned (including any transferee of any of the Shares).

         Any term or provision of this proxy which is invalid or unenforceable,
in any jurisdiction will, as to that jurisdiction, be ineffective to the extent
of such invalidity or unenforceability without rendering invalid or
unenforceable the remaining terms and provisions of this proxy or affecting the
validity or enforceability of any of the terms or provisions of this proxy in
any other jurisdiction. If any provision of this proxy is so broad as to be
unenforceable, the provision will be interpreted to be only so broad as is
enforceable.

         This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.

                        STOCK TENDER AND VOTING AGREEMENT


     STOCK TENDER AND VOTING AGREEMENT (this "Agreement"), dated as of July 6,
1999 by and among Cheryl Moreno ("Stockholder"), Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Saturn"), and SSI Acquisition Corp.,
a Delaware corporation and a wholly-owned subsidiary of Saturn ("Merger Sub").

                                    RECITALS

     A.   Concurrently herewith Saturn, Merger Sub and Smartflex Systems, Inc.,
a Delaware corporation ("Smartflex"), are entering into an Agreement and Plan of
Merger of even date herewith (the "Merger Agreement"), pursuant to which Merger
Sub agrees to make a tender offer (the "Offer") for all of the outstanding
shares of common stock, $.0025 par value (the "Common Stock") of Smartflex, at a
price of $10.50 per share (the "Offer Price"), in cash, following which
Smartflex will be merged with and into Merger Sub, with Smartflex as the
Surviving Corporation (the "Merger").

     B.   Stockholder beneficially owns (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as
of the date hereof, 3,500 shares of Common Stock (the "Existing Shares",
together with any shares of Common Stock beneficial ownership of which is
acquired by Stockholder after the date hereof and prior to the termination
hereof, hereinafter collectively referred to as the "Shares").

     C.   As a condition to their willingness to enter into the Merger
Agreement, Saturn and Merger Sub have requested that Stockholder agree, and
Stockholder has agreed, to enter into this Agreement.

     D.   Saturn and Merger Sub have entered into the Merger Agreement in
reliance on Stockholder's representations, warranties, covenants and agreement
hereunder.

     THEREFORE, the parties agree as follows:

     1.   Agreement to Tender and Vote; Irrevocable Proxy.

          1.1  Tender. Stockholder agrees to validly tender all Shares
     beneficially owned by it pursuant to the Offer within ten business days of
     commencement of the Offer, and not withdraw any such Shares, except to the
     extent that the tender of shares (including Shares acquired after the date
     hereof) pursuant to the Offer would subject Stockholder to liability under
     Section 16(b) of the Exchange Act.

          1.2  Voting. Stockholder hereby agrees that, during the time this
     Agreement is in effect, at any meeting of the stockholders of Smartflex,
     however called, and in any action by consent of the stockholders of
     Smartflex, Stockholder will: (a) vote all Shares beneficially owned by it
     in favor of the Merger; (b) vote all Shares beneficially owned by it
     against any action or agreement that would result in a breach of any
     covenant or any representation or warranty or any other obligation or
     agreement of Smartflex under or pursuant to the Merger Agreement; (c) vote
     all Shares beneficially owned by it against

<PAGE>   2

     any action or agreement that would impede, interfere with, delay, postpone
     or attempt to discourage, the Merger or the Offer including, but not
     limited to, (i) any corporate transaction not entered into in the ordinary
     course of business (other than the Merger), including, but not limited to,
     a merger, other business combination, reorganization, consolidation,
     recapitalization, dissolution or liquidation involving Smartflex, (ii) a
     sale or transfer of a material amount of assets of Smartflex or any of its
     subsidiaries, (iii) any change in the board of directors of Smartflex, (iv)
     any material change in the capitalization of Smartflex, (v) any change in
     the charter, by-laws or other organizational or constitutive documents of
     Smartflex, or (vi) any other material change in the corporate structure or
     business of Smartflex; and (d) without limiting the foregoing, consult with
     Saturn and vote all Shares beneficially owned by it in such manner as is
     determined by Saturn to be in compliance with the provisions of this
     Section 1.2. Stockholder acknowledges receipt and review of a copy of the
     Merger Agreement. Notwithstanding the foregoing, Stockholder may take any
     action in his or her role as a director or officer of Smartflex as
     permitted under Sections 6.04 and 8.01(e) of the Merger Agreement. This
     Agreement is intended to bind Stockholder only with respect to the specific
     matters set forth herein and shall not prohibit the Stockholder from acting
     in accordance with his or her fiduciary duties to Smartflex.

          1.3. Irrevocable Proxy. Contemporaneously with the execution of this
     Agreement: (i) Stockholder will deliver to Saturn a proxy in the form
     attached hereto as Exhibit A, which will be irrevocable to the fullest
     extent permitted by law (the "Proxy"), with respect to all Shares owned of
     record by Stockholder; and (ii) Stockholder will cause to be delivered to
     Saturn additional Proxies executed on behalf of each record owner of any
     Shares owned beneficially (but not owned of record) by Stockholder.

     2.   Representations and Warranties of Stockholder. Stockholder represents
and warrants to Saturn and Merger Sub as follows:

          2.1 Ownership of Shares. On the date hereof the Existing Shares are
all of the Shares currently beneficially owned by Stockholder. On the Closing

additional shares of Common Stock other than pursuant to options issued under
the Stock Option Plans (as defined in the Merger Agreement), Stockholder
currently has with respect to the Existing Shares, and at Closing will have with
respect to the Shares, good, valid and marketable title, free and clear of all
liens, encumbrances, restrictions, options, warrants, rights to purchase, voting

encumbrances created by this Agreement and other than restrictions on transfer
under applicable, Federal and State securities laws).

          2.2 Power; Binding Agreement. Stockholder has the full legal capacity,
right, power and authority to enter into and perform all of Stockholder's

agreement, stockholders agreement or voting trust. This Agreement has been duly
executed and delivered by Stockholder and constitutes a legal, valid and binding
agreement of Stockholder, enforceable in accordance with its terms. Neither the
execution or delivery of this Agreement nor the consummation by Stockholder of
the

                                       2
<PAGE>   3

transactions contemplated hereby will (a) other than filings required under the
federal or state securities laws, require any consent or approval of or filing
with any Governmental or other regulatory body, or (b) constitute a violation
of, conflict with or constitute, a default under (i) any law, rule or regulation
applicable to Stockholder, or (ii) any order, judgment or decree by which
Stockholder is bound.

          2.3. Finder's Fees. No person is, or will be, entitled to any

constitutes a legal, valid and binding agreement of Saturn and Merger Sub,
enforceable in accordance with its terms. Neither the execution of this
Agreement nor the consummation by Saturn or Merger Sub of the transactions
contemplated hereby will (a) require any consent or approval of or filing with
any governmental or other regulatory body, or (b) constitute a violation of,
conflict with or constitute a default under (i) any law, rule or regulation
applicable to Saturn or Merger Sub, or (ii) any order, judgment or decree to
which Saturn or Merger Sub is bound.

          3.2. Finder's Fees. No person is, or will be, entitled to any

finder's fees referred to in the Merger Agreement.

     4.   Termination. This Agreement (other than the provisions of Sections
5, 6 and 19 which will survive any termination of this Agreement), will
terminate on the earliest to occur of (a) the date on which Merger Sub accepts
for payment the Shares tendered in the Offer, so long as the Shares are so
tendered and not withdrawn, (b) the Effective Time (as defined in the Merger
Agreement), and (c) simultaneously with the termination of the Merger Agreement
in accordance with its terms.

public disclosure, Stockholder agrees that it will not disclose or discuss these
matters with anyone (other than officers, directors, legal


                                       3
<PAGE>   4

counsel and advisors of Stockholder or Smartflex, if any) not a party to this
Agreement, without prior written consent of Saturn, except as provided herein or
in the Merger Agreement and except for filings required pursuant to the Exchange
Act, and the rules and regulations thereunder or disclosures Stockholder's legal
counsel advises in writing are necessary in order to fulfill Stockholder's
obligations imposed by law, in which event Stockholder will give prompt prior
notice of such disclosure to Saturn and cooperate with Saturn in obtaining a
protective order or in limiting such disclosure.

     7.   Certain Covenants of Stockholder.

          7.1  Except in accordance with the provisions of this Agreement,
Stockholder agrees, while this Agreement is in effect, not to, directly or
indirectly:

               (a)  sell, transfer,  pledge,  encumber,  assign or otherwise
dispose of, or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, encumbrance,
assignment or other disposition of, any of the Shares;

               (b)  grant any proxies, deposit any Shares into a voting trust or
enter into a voting agreement with respect to any Shares; or

               (c)  solicit, initiate or encourage the submission of any
proposal or offer from any person (other than Saturn or Merger Sub) relating to
any acquisition or purchase of all or any material portion of the assets of, or
any equity interest in (other than pursuant to the exercise of options
outstanding on the date hereof), Smartflex or any subsidiary of Smartflex, or
any merger, consolidation, business combination, reorganization,
recapitalization or similar transaction involving Smartflex or any subsidiary of
Smartflex (each a "Competing Transaction"), or participate in any discussions or
negotiations regarding, or furnish to any other person any information with
respect to, or otherwise, cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any person (other than
Saturn and Merger Sub) to do or seek any of the foregoing, Stockholder will
cease and cause to be terminated any existing activities, discussions or
negotiations by or on its behalf with any person (other than Saturn and Merger
Sub) conducted heretofore with respect to any Competing Transaction and will
promptly notify Saturn following receipt of any request by any person (other
than Saturn or Merger Sub) relating to any possible Competing Transaction or
information concerning Smartflex. Nothing contained herein will prohibit
Stockholder, solely in his capacity as an officer or as a member of the board of
directors of Smartflex (the "Board"), from furnishing information to, or
entering into discussions or negotiations with, any person (other than Saturn
and Merger Sub) in connection with an unsolicited proposal involving a
fully-financed (as represented by such person) Competing Transaction which is
made in writing by such person (other than Saturn and Merger Sub) and which, if
consummated, would provide consideration per share, of Common Stock to the
stockholders of Smartflex in excess of the Offer Price if, and only to the
extent that, the Board determines in good faith, based upon the advice of SG
Cowen Securities Corporation and the written advice of Stradling Yocca Carlson &
Rauth, that such action is required for the Board to comply with its fiduciary
duties to stockholders under Delaware law.

     11.  Entire Agreement; Amendment. This Agreement, together with the
documents expressly referred to herein, constitute the entire agreement among
the parties hereto with respect to the subject matter contained herein and
supersede all prior agreements and understandings among the parties with respect
to such subject matter. This Agreement may not be modified, amended, altered or
supplemented except by an agreement in writing executed by the party against
whom such modification, amendment, alteration or supplement is sought to be
enforced.

     12.  Assigns. This Agreement will be binding upon and inure to the benefit
of the parties hereto and their respective successors, assigns and personal
representatives, but neither this Agreement nor any of the rights, interests or
obligations hereunder will be assigned by any of the parties hereto without the
prior written consent of the other parties, except that Merger Sub may assign
any or all of its rights and obligations hereunder to Saturn or any direct or
indirect wholly-owned subsidiary of Saturn without the consent of Stockholder or
Company, but no such transfer will relieve Merger Sub of its obligations under
this Agreement if such subsidiary does not perform the obligations of Merger Sub
hereunder.

     13.  Governing Law; Jurisdiction; and Consent to Service. Except as
expressly set forth below, this Agreement will be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
In addition, each of Stockholder, Merger Sub and Saturn hereby agrees that any
dispute arising out of this Agreement will be heard in the United States
District Court for the Central District of California and, in connection
therewith, each party to

                                       6
<PAGE>   7

this Agreement hereby consents to the jurisdiction of such courts and agrees
that any service of process in connection with any dispute arising out of this
Agreement or the Merger may be given to any other party hereto by certified
mail, return receipt requested, at the respective addresses set forth in Section
10 above.

     14.  Injunctive Relief. The parties agree that in the event of a breach of
any provision of this Agreement, the aggrieved party may be without an adequate
remedy at law. The parties therefore agree that in the event of a breach of any
provision of this Agreement, the aggrieved party will be entitled to obtain in
any court of competent jurisdiction a decree of specific performance or to
enjoin the continuing breach of such provision, in each case without the
requirement that a bond be posted, as well as to obtain damages for breach of
this Agreement. By seeking or obtaining such relief, the aggrieved party will
not be precluded from seeking or obtaining any other relief to which it may be
entitled.

     15.  Counterparts; Facsimile Signatures. This Agreement may be executed in
any number of counterparts (including by facsimile signature), each of which
will be deemed to be an original and all of which together will constitute one
and the same document.

     16.  Severability. Any term or provision of this Agreement which is invalid
or unenforceable in any jurisdiction will, as to such jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision will be interpreted
to be only so broad as is enforceable.

     17.  Further Assurances. Each party hereto will execute and deliver such
additional documents as may be necessary or desirable to consummate the
transactions contemplated by this Agreement.

     18.  Third Party Beneficiaries. Nothing in this Agreement, expressed or
implied, will be construed to give any person other than the parties hereto any
legal or equitable right, remedy or claim under or by reason of this Agreement
or any provision contained herein.

     19.  Legal Expenses. In the event any legal proceeding is commenced by any
party to this Agreement to enforce or recover damages for any breach of the
provisions hereof, the prevailing party in such legal proceeding will be
entitled to recover in such legal proceeding from the losing party such
prevailing party's costs and expenses incurred in connection with such legal
proceedings, including reasonable attorneys fees. The provisions of this Section
19 will survive the Closing hereunder.

     20.  Amendment and Modification. This Agreement may be amended, modified
and supplemented only by a written document executed by Saturn, Merger Sub and
Stockholder.

                                    EXHIBIT A

                            Form Of Irrevocable Proxy

     The undersigned stockholder of Smartflex Systems, Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Wallace K. Tsuha, Jr., Jereen Trudell and
Saturn Electronics & Engineering, Inc. ("Saturn"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the issued and outstanding shares of capital stock of Smartflex owned of
record by the undersigned as of the date of this proxy, which shares are
specified on the final page of this proxy and (ii) any and all other shares of
capital stock of Smartflex which the undersigned may acquire after the date
hereof (the shares of the capital stock of Smartflex referred to in (clauses (i)
and (ii) of the immediately preceding sentence are collectively referred to as
the "Shares"). Upon the execution hereof all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.

     This proxy is irrevocable, is coupled with an interest and is granted in
connection with a Stock Tender and Voting Agreement, dated as of the date
hereof, among Saturn, SSI Acquisition Corp. and the undersigned (the "Stock
Tender Agreement"), and is granted in consideration of Saturn entering into the
Agreement and Plan of Merger, dated as of the date hereof, among Saturn, SSI
Acquisition Corp. and Smartflex (the "Merger Agreement"). Capitalized terms used
but not otherwise defined in this proxy have the meanings ascribed to such terms
in the Merger Agreement.

     The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Shares at any time until the earlier to occur of the
valid termination of the Merger Agreement pursuant to Section 8.01 thereof or
the Effective Time at any meeting of the stockholders of Smartflex, however
called, or in any written action by consent of stockholders of Smartflex: (a) in
favor of the Merger; (b) against any action or agreement that would result in a
breach of any covenant or any representation or warranty or any other obligation
or agreement of Smartflex under or pursuant to the Merger Agreement; or (c)
against any action or agreement that would impede, interfere with, delay,
postpone, or attempt to discourage the Merger or the Offer including, but not
limited to, (i) any corporate transaction not entered into in the ordinary
course of business (other than the Merger), including, but not limited to, a
merger, other business combination, reorganization, consolidation,
recapitalization, dissolution or liquidation involving Smartflex, (ii) a sale or
transfer of a material amount of assets of Smartflex or any of its subsidiaries,
(iii) any change in the board of directors of Smartflex, (iv) any material
change in the capitalization of Smartflex, (v) any change in the charter,
by-laws or other organizational or constitutive documents of Smartflex, or (v)
any other material change in the corporate structure or business of Smartflex.

     This proxy will be binding upon the heirs, successors and assigns of the
undersigned (including any transferee of any of the Shares).

                                       9

<PAGE>   10


     Any term or provision of this proxy which is invalid or unenforceable, in
any jurisdiction will, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering invalid or unenforceable
the remaining terms and provisions of this proxy or affecting the validity or
enforceability of any of the terms or provisions of this proxy in any other
jurisdiction. If any provision of this proxy is so broad as to be unenforceable,
the provision will be interpreted to be only so broad as is enforceable.

     This proxy will terminate immediately upon the earlier of the valid
termination of the Merger Agreement pursuant to Section 8.01 thereof or the
Effective Time.
