agreement  between the Company and Roan Meyers Associates L.P. dated February 6,
2002 (the "Agreement").

SECTION I.     TRANSFER OR EXCHANGE OF WARRANT.

     The Company  shall be entitled to treat the  Warrantholder  as the owner in
fact hereof for all purposes and shall not be bound to recognize  any  equitable
or other claim to or interest in this  Warrant on the part of any other  person.
This Warrant shall be transferable only with the consent of the Company and such
transfer  will be effective  only upon  reflection  on the books of the Company,
maintained  at its principal  office upon  delivery of this Warrant  Certificate
duly  endorsed  by the  Warrantholder  or by his  duly  authorized  attorney  or
representative,  or accompanied by proper evidence of succession,  assignment or
authority to transfer.  Upon any  registration  of transfer,  the Company  shall
deliver a new  Warrant  Certificate  or  Certificates  to the  persons  entitled
thereto.

SECTION II.    TERM OF WARRANT; EXERCISE OF WARRANTS.

     A. Vesting. A portion of this Warrant Certificate representing the right to
purchase  500,000  shares  of  Warrant  Stock  shall  vest  immediately  and  be
exercisable  on  or  after  February  6,  2002.  The  portion  of  this  Warrant
Certificate representing the right to purchase the remaining 1,000,000 shares of
Warrant  Stock shall vest and become  exercisable  in  increments of 200,000 for
each $1 million in capital financing  received by the Company for which a fee is
due to the Warrantholder pursuant to an agreement,  the terms of which are to be
agreed  upon  prior  to such  financings  as  described  in  paragraph  2 of the
Agreement.

     B.  Termination.  The  Company  may,  in its sole  discretion,  extend  the
Termination Date with respect to the exercise of this Warrant upon notice to the
Warrantholder. As used herein, "Termination Date" shall be deemed to include any
such extensions.

     C.  Exercise.  This Warrant shall be exercised by surrender to the Company,
at its principal office, of this Warrant Certificate, together with the Purchase
Form attached hereto duly completed and signed,  and upon

<PAGE>

payment to the Company of the Exercise Price for the number of shares of Warrant
Stock in  respect  of which  this  Warrant  is then  exercised.  Payment  of the
aggregate  Exercise Price shall be made in cash or by certified or official bank
check.

     D. Warrant Certificate.  Subject to Section III hereof, upon such surrender
of this Warrant Certificate and payment of the Exercise Price as aforesaid,  the
Company  shall issue and cause to be delivered  to or upon the written  order of
the Warrantholder a certificate or certificates for the number of full shares of
Warrant  Stock so purchased  upon the exercise of such  Warrant,  together  with
cash, as provided in Section VI hereof,  in respect of any fractional  shares of
Warrant  Stock  otherwise  issuable upon such  surrender.  Such  certificate  or
certificates  representing the Warrant Stock shall be deemed to have been issued
and any person so  designated to be named therein shall be deemed to have become
a holder of record of such shares of Warrant  Stock as of the date of receipt by
the Company of this Warrant  Certificate  and payment of the  Exercise  Price as
aforesaid;  provided, however, that if, at the date of surrender of this Warrant
Certificate  and  payment of the  Exercise  Price,  the  transfer  books for the
Warrant  Stock or other  class of stock  purchasable  upon the  exercise of this
Warrant  shall be closed,  the  certificate  or  certificates  for the shares of
Warrant Stock in respect of which this Warrant is then exercised shall be deemed
issuable as of the date on which such books shall next be opened (whether before
or after the Termination Date) and until such date the Company shall be under no
duty to deliver  any  certificate  for such  shares of Warrant  Stock;  provided
further,  however,  that the transfer books of record, unless otherwise required
by law, shall not be closed at any one time for a period longer than twenty (20)
days. The rights of purchase  represented by this Warrant shall be  exercisable,
at the  election  of the  Warrantholder,  either in full or from time to time in
part,  and, in the event that this Warrant is exercised in respect of fewer than
all of the shares of Warrant  Stock  purchasable  on such  exercise  at any time
prior  to  the  Termination  Date,  a new  Warrant  Certificate  evidencing  the
remaining Warrant or Warrants will be issued,  and the Company shall deliver the
new Warrant  Certificate  or  Certificates  pursuant to the  provisions  of this
Section.

SECTION III.   PAYMENT OF TAXES.

     The Company will pay all documentary  stamp taxes, if any,  attributable to
the initial  issuance of the shares of Warrant  Stock upon the  exercise of this
Warrant;  provided,  however,  that the Warrantholder shall pay any tax or taxes
which  may be  payable  in  respect  of any  transfer  involved  in the issue or
delivery of Warrant  Certificates or the  certificates for the shares of Warrant
Stock in a name  other than that of the  Warrantholder  in respect of which this
Warrant or shares of Warrant Stock are issued.

SECTION IV.    MUTILATED OR MISSING WARRANT CERTIFICATES.

     In case  this  Warrant  Certificate  shall be  mutilated,  lost,  stolen or
destroyed,  the Company shall,  at the request of the  Warrantholder,  issue and
deliver,  in  exchange  and  substitution  for  and  upon  cancellation  of this
certificate if mutilated, or in lieu of and in substitution for this certificate
if lost,  stolen or  destroyed,  a new  Warrant  Certificate  of like  tenor and
representing an equivalent right or interest,  but only upon receipt of evidence
satisfactory  to the Company of such loss,  theft or destruction of this Warrant
Certificate and indemnity, if requested, also satisfactory to the Company.

SECTION V.     RESERVATION OF SHARES OF WARRANT STOCK.

     There has been  reserved,  and the Company shall at all times keep reserved
so long as this Warrant remains outstanding,  out of its authorized Common Stock
a number of shares of Common Stock sufficient to provide for the exercise of the
rights of purchase  represented  by this  Warrant.  The  transfer  agent for the
Common Stock and every subsequent transfer agent for any shares of the Company's
capital  stock  issuable  upon the exercise of this Warrant will be  irrevocably
authorized and directed at all times to reserve such number of authorized shares
as shall be requisite for such purpose.

                                       2
<PAGE>

SECTION VI.    FRACTIONAL SHARES.

     No  fractional  shares or scrip  representing  fractional  shares  shall be
issued upon the  exercise of this  Warrant.  With  respect to any  fraction of a
share called for upon the exercise of this Warrant, the Company shall pay to the
Warrantholder an amount in cash equal to such fraction multiplied by the current
market price of such fractional share. "Market Price", as of any date means, (i)
the last  reported  sale price for the shares of Common Stock as reported by the
National  Association of Securities Dealers Automated  Quotation National Market
System,  ("NASDAQ-NMS"),  (ii) the  closing  bid price for the  shares of Common
Stock as reported by the National  Association of Securities  Dealers  Automated
Quotation  System  ("NASDAQ") if the shares are not traded on NASDAQ-NMS,  (iii)
the average of the closing bid and closing  asked  prices of the Common Stock as
reported  by the  National  Quotations  Bureau if the  shares  are not traded on
NASDAQ;  (iv) the last  reported  sale price,  if the shares of Common Stock are
listed  on a  national  securities  exchange  or (v) if market  value  cannot be
calculated as of such date on any of the foregoing  basis, the fair market price
determined  by the Board of  Directors of the  Company,  acting with  reasonable
business judgment.

SECTION VII.   EXERCISE PRICE; ANTI-DILUTION PROVISIONS.

     A. Exercise  Price.  The shares of Warrant Stock shall be purchasable  upon
the exercise of this Warrant, at the applicable Exercise Price. The Company may,
in its sole discretion,  reduce the Exercise Price applicable to the exercise of
this Warrant upon notice to the Warrantholder.  As used herein, "Exercise Price"
shall be deemed to include any such reduction.

     If the Company  shall at any time issue  Common Stock by way of dividend or
other  distribution  on any  stock of the  Company  or  effect a stock  split or
reverse  stock split of the  outstanding  shares of Common  Stock,  the Exercise
Price shall be  proportionately  decreased in the case of such  issuance (on the
day following the date fixed for  determining  stockholders  entitled to receive
such  dividend or other  distribution  or such stock  split) or increased in the
case of such  reverse  stock  split (on the date that such  reverse  stock split
shall become effective), by multiplying the Exercise Price in effect immediately
prior to the stock dividend or other distribution,  stock split or reverse stock
split by a fraction,  the  numerator  of which is the number of shares of Common
Stock   outstanding   immediately   prior  to  such  stock   dividend  or  other
distribution,  stock split or reverse stock split,  and the denominator of which
is the number of shares of Common Stock outstanding immediately after such stock
dividend or other distribution, stock split or reverse stock split.

     B. No  Impairment.  The Company (a) will not  increase the par value of any
shares of stock  receivable  upon the exercise of this Warrant  above the amount
payable therefor upon such exercise, and (b) will take all such action as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and  nonassessable  shares of Common  Stock upon the exercise of this
Warrant.

     C. Number of Shares  Adjusted.  Upon any  adjustment of the Exercise  Price
pursuant to this Warrant, the Warrantholder shall thereafter (until another such
adjustment)  be entitled to purchase upon the exercise of this  Warrant,  at the
new Exercise Price, the number of shares,  calculated to the nearest full share,
obtained by multiplying the number of shares of Warrant Stock initially issuable
upon exercise of this Warrant by the Exercise Price in effect on the date hereof
and dividing the product so obtained by the new Exercise Price.

SECTION VIII.  RECLASSIFICATION, REORGANIZATION OR MERGER.

     In case of any reclassification,  capital reorganization or other change of
outstanding  shares of Common  Stock of the Company  (other than a change in par
value or as a result of an issuance of Common  Stock by way of dividend or other
distribution  or of a stock  split or  reverse  stock  split)  or in case of any
consolidation or merger of the Company with or into another  corporation  (other
than a merger with a subsidiary  in which  merger the Company is the  continuing
corporation  and  which  does  not  result  in  any  reclassification,   capital
reorganization  or other  change of  outstanding  shares of Common  Stock of the
Company  issuable  upon  exercise  of this  Warrant)  or in case of any  sale or
conveyance to another  corporation of the property of the Company as an entirety
or substantially as an entirety,  the Company shall cause effective provision to
be made so that the Warrantholder shall have the right thereafter, by exercising
this  Warrant,  to  purchase  the kind and  amount  of shares of stock and other
securities and property the Warrantholder would have been entitled to receive if
the  Warrantholder  had  exercised  this  Warrant

                                       3
<PAGE>

immediately  prior to such  reclassification,  capital  reorganization  or other
change,  consolidation,  merger,  sale or conveyance.  Any such provision  shall
include  provision for adjustments which shall be as nearly equivalent as may be
practicable  to the  adjustments  provided for in this  Warrant.  The  foregoing
provisions   of   this   Section   shall    similarly    apply   to   successive
reclassifications, capital reorganizations and changes of shares of Common Stock
and to successive consolidations, mergers, sales and conveyances.

SECTION IX.    REGISTRATION RIGHTS

     The Company  shall use its best  efforts to file a  registration  statement
(the  "Registration  Statement")  under the Act to  register  the  resale of the
Warrant Stock.  The Company further agrees to use its best efforts to cause such
Registration Statement to become effective.

     In connection with the  Registration  Statement,  the  Warrantholder  shall
provide the Company,  from time to time, as reasonably requested by the Company,
written information  concerning its ownership of the Company's  securities,  its
intentions  concerning  the sale of its Warrant  Stock and such other matters as
are  required  in order to enable the  Company to  prepare,  file and obtain the
effectiveness  of  such  Registration  Statement.  Notwithstanding  any  of  the
foregoing,  the Company shall not be required to maintain the  effectiveness  of
the  Registration  Statement with respect to any Warrant Stock for more than two
(2) years after the purchase of such Warrant Stock pursuant to the terms hereof.

     The Company shall bear the entire cost and expense of any such registration
hereunder.  Notwithstanding the foregoing, the Warrantholder shall bear the fees
of all persons retained by it, such as counsel and accountants, and any transfer
taxes or underwriting  discounts or commissions applicable to the Warrant Shares
sold by it pursuant to the Registration Statement.

SECTION X.     NOTICES TO WARRANTHOLDERS.

Company shall pay any dividend or make any distribution upon the Common Stock or

stating  the date on which (i) a record is to be taken for the  purpose  of such
dividend  or  distribution,  or  (ii)  such  reclassification,   reorganization,
consolidation, merger, conveyance, lease, dissolution, liquidation or winding up
is to take place and the date,  if any, as of which the holders of Common  Stock
of record  shall be  entitled  to  exchange  their  shares  of Common  Stock for
securities   or  other   property   deliverable   upon  such   reclassification,
reorganization,  consolidation,  merger, conveyance, dissolution, liquidation or
winding up.

of the Company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

be treated as continuing intact while the individual is on sick leave or other
leave of absence approved by the Company. Where the period of leave exceeds 90
days and the individual's right to reemployment is not guaranteed either by
statute or by contract, the employment relationship will be deemed to have
terminated on the 91st day of such leave.

the day of such determination, as reported in The Wall Street Journal or such
other source as the Board deems reliable, or;

Stock, the Fair Market Value thereof shall be determined in good faith by the

number of shares of Common Stock which have been authorized for issuance under
the Plan but not yet placed under option.

            (q) "Subsidiary" shall mean a corporation, domestic or foreign, of
which not less than 50% of the voting shares of stock are held by the Company or

such Employee (or any other person whose stock would be attributed to such
Employee pursuant to Section 424(d) of the Code) would own stock and/or hold
outstanding options to purchase stock possessing five percent (5%) or more of
the total combined voting power or value of all classes of stock of the Company
or of a Subsidiary, or (ii) which permits his or her rights to purchase stock
under all employee stock purchase plans of the Company and Subsidiaries to
accrue at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) worth of
stock (determined at the fair market value of the stock at the time such option
is granted) for each calendar year in which such option is outstanding at any
time.

        4. Offering Periods. The Plan shall be implemented by consecutive and
overlapping Offering Periods, with the first Offering Period beginning the First
Commencement Date and continuing unless terminated in accordance with the Plan.
The Board shall have the power to change the duration of Offering Periods with
respect to future offerings without stockholder approval if such change is
announced at least fifteen (15) days prior to the scheduled beginning of the
first Offering Period to be affected. Absent action by the Board, each Offering
Period shall be for a period of approximately twenty-four months (24) and new
Offering Periods shall commence on the first Trading Day of April and October of
each year and shall terminate on the last Trading Day in the March or September
twenty-four (24) months later; provided, however, that the first Offering Period
under the Plan shall commence on the First Commencement Date and shall terminate
on the last Trading Day in March 1995.

        5. Participation.

            (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office at
least 14 days prior to the applicable Enrollment Date.

            (b) Payroll deductions for a participant shall commence on the first
payroll period following the Enrollment Date and shall end on the last payroll
period in the Offering Period, unless sooner terminated by the participant as
provided in paragraph 10.

                                      -3-

<PAGE>

        6. Payroll Deductions.

            (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day
during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period, and the aggregate of such payroll deductions during the Offering Period
shall not exceed ten percent (10%) of the participant's Compensation during said
Offering Period.

            (b) All payroll deductions made for a participant shall be credited
to his or her account under the Plan and will be withheld in whole percentages
only. A participant may not make any additional payments into such account.

            (c) A participant may discontinue his or her participation in the
Plan as provided in paragraph 10, or may increase or decrease the rate of his or
her payroll deductions during the current Purchase Period by filing with the
Company a new subscription agreement authorizing such a change in the payroll
deduction rate. The change in rate shall be effective with the first full
payroll period following five (5) business days after the Company's receipt of
the new subscription agreement unless the Company elects to process a given
change in participation more quickly. A participant's subscription agreement
shall remain in effect for successive Purchase Periods and Offering Periods
unless terminated as provided in paragraph 10. The Board shall be authorized to
limit the number of participation rate changes during any Offering Period.

            (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and paragraph 3(b) herein, a participant's
payroll deductions may be decreased to 0% at such time during any Purchase
Period which is scheduled to end during the current calendar year (the "Current
Purchase Period") that the aggregate of all payroll deductions which were
previously used to purchase stock under the Plan in a prior Purchase Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Purchase Period equal $21,250. Payroll deductions
shall recommence at the rate provided in such participant's subscription
agreement at the beginning of the first Purchase Period which is scheduled to
end in the following calendar year, unless terminated by the participant as
provided in paragraph 10.

            (e) At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but will not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefit attributable to sale or early disposition of
Common Stock by the Employee.

            7. Grant of Option. On the Enrollment Date of each Offering Period,
each eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of

                                      -4-

<PAGE>

shares of the Company's Common Stock determined by dividing such Employee's
payroll deductions accumulated prior to such Exercise Date and retained in the
Participant's account as of the Exercise Date by the applicable Purchase Price;
provided that in no event shall an Employee be permitted to purchase during each
Purchase Period more than a number of shares of Common Stock determined by
dividing $12,500 by the fair market value of a share of the Company's Common
Stock on the Enrollment Date, and provided further that such purchase shall be
subject to the limitations set forth in Section 3(b) and 12 hereof. Exercise of
the option shall occur as provided in Section 8, unless the participant has
withdrawn pursuant to Section 10, and the option shall expire on the last day of
the Offering Period.

        8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in paragraph 10 below, his or her option for the purchase of shares of
Common Stock will be exercised automatically on each Exercise Date, and the
maximum number of full shares of Common Stock subject to option shall be
purchased for such participant at the applicable Purchase Price with the
accumulated payroll deductions in his or her account. No fractional shares of
Common Stock will be purchased; any payroll deductions accumulated in a
participant's account which are not sufficient to purchase a full share of
Common Stock shall be retained in the participant's account for the subsequent
Purchase Period, subject to earlier withdrawal by the participant as provided in
paragraph 10. Any other monies left over in a participant's account after the
final Exercise Date of an Offering Period shall be returned to the participant.
During a participant's lifetime, a participant's option to purchase shares of
Common Stock hereunder is exercisable only by him or her.

        9. Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares of Common Stock occurs, the Company shall arrange the
delivery to each participant, as appropriate, of a certificate representing the
shares of Common Stock purchased upon exercise of his or her option.

        10. Withdrawal; Termination of Employment.

            (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account will be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period will be automatically terminated, and no further payroll deductions for
the purchase of shares of Common Stock will be made during the Offering Period.
If a participant withdraws from an Offering Period, payroll deductions will not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

            (b) Upon a participant's ceasing to be an Employee for any reason or
upon termination of a participant's employment relationship (as described in
Section 2(g)), the payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option will be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under paragraph 14, and such participant's option
will be automatically terminated.

                                      -5-

<PAGE>

        11. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

        12. Stock.

            (a) The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 2,300,000 shares,
subject to adjustment upon changes in capitalization of the Company as provided
in paragraph 18. If on a given Exercise Date the number of shares of Common
Stock with respect to which options are to be exercised exceeds the number of
shares of Common Stock then available under the Plan, the Company shall make a
pro rata allocation of the shares of Common Stock remaining available for
purchase in as uniform a manner as shall be practicable and as it shall
determine to be equitable.

            (b) The participant will have no interest or voting right in shares
of Common Stock covered by his or her option until such option has been
exercised.

            (c) Shares of Common Stock to be delivered to a participant under
the Plan will be registered in the name of the participant or in the name of the
participant and his or her spouse.

        13. Administration.

            (a) Administrative Body. The Plan shall be administered by the Board
of the Company or a committee of members of the Board appointed by the Board.
The Board or its committee shall have full and exclusive discretionary authority
to construe, interpret and apply the terms of the Plan, to determine eligibility
and to adjudicate all disputed claims filed under the Plan. Every finding,
decision and determination made by the Board or its committee shall, to the full
extent permitted by law, be final and binding upon all parties. Members of the
Board who are eligible Employees are permitted to participate in the Plan,
provided that:

                (1) Members of the Board who are eligible to participate in the
Plan may not vote on any matter affecting the administration of the Plan or the
grant of any option pursuant to the Plan.

                (2) If a Committee is established to administer the Plan, no
member of the Board who is eligible to participate in the Plan may be a member
of the Committee.

            (b) Rule 16b-3 Limitations. Notwithstanding the provisions of
Subsection (a) of this Section 13, in the event that Rule 16b-3 promulgated
under The Securities Exchange Act of 1934, as amended, or any successor
provision ("Rule 16b-3") provides specific requirements for the administrators
of plans of this type, the Plan shall be only administered by such a body and in
such a manner as shall comply with the applicable requirements of Rule 16b-3.
Unless permitted by Rule 16b-3, no discretion concerning decisions regarding the
Plan shall be afforded to any committee or person that is not "disinterested" as
that term is used in Rule 16b-3.

                                      -6-

<PAGE>

        14. Designation of Beneficiary.

            (a) A participant may file a written designation of a beneficiary
who is to receive any shares of Common Stock and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares of Common Stock and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death prior to exercise of the option. If a participant is
married and the designated beneficiary is not the spouse, spousal consent shall
be required for such designation to be effective.

            (b) Such designation of beneficiary may be changed by the
participant (and his or her spouse, if any) at any time by written notice. In
the event of the death of a participant and in the absence of a beneficiary
validly designated under the Plan who is living at the time of such
participant's death, the Company shall deliver such shares of Common Stock
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares of Common
Stock and/or cash to the spouse or to any one or more dependents or relatives of
the participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

        15. Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares of Common Stock under the Plan may be assigned, transferred,
pledged or otherwise disposed of in any way (other than by will, the laws of
descent and distribution or as provided in paragraph 14 hereof) by the
participant. Any such attempt at assignment, transfer, pledge or other
disposition shall be without effect, except that the Company may treat such act
as an election to withdraw funds from an Offering Period in accordance with
paragraph 10.

        16. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

        17. Reports. Individual accounts will be maintained for each participant
in the Plan. Statements of account will be given to participating Employees at
least annually, which statements will set forth the amounts of payroll
deductions, the Purchase Price, the number of shares of Common Stock purchased
and the remaining cash balance, if any.

        18. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.

            (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves as well as the price per share of
Common Stock covered by each option under the Plan which has not yet been
exercised, shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or

                                      -7-

<PAGE>

decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration". Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issue by the Company of shares of stock
of any class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an option. The Board may,
if it so determines in the exercise of its sole discretion, make provision for
adjusting the Reserves, as well as the price per share of Common Stock covered
by each outstanding option, in the event the Company effects one or more
reorganizations, recapitalizations, rights offerings or other increases or
reductions of shares of its outstanding Common Stock.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Periods will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

            (c) Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each option under the Plan shall be assumed or
an equivalent option shall be substituted by such successor corporation or a
parent or subsidiary of such successor corporation, unless the Board determines,
in the exercise of its sole discretion and in lieu of such assumption or
substitution, to shorten the Offering Periods then in progress by setting a new
Exercise Date (the "New Exercise Date"). If the Board shortens the Offering
Periods then in progress in lieu of assumption or substitution in the event of a
merger or sale of assets, the Board shall notify each participant in writing, at
least ten (10) days prior to the New Exercise Date, that the Exercise Date for
his or her option has been changed to the New Exercise Date and that his or her
option will be exercised automatically on the New Exercise Date, unless prior to
such date he has withdrawn from the Offering Period as provided in paragraph 10.
For purposes of this paragraph, an option granted under the Plan shall be deemed
to be assumed if, following the sale of assets or merger, the option confers the
right to purchase, for each share of stock subject to the option immediately
prior to the sale of assets or merger, the consideration (whether stock, cash or
other securities or property) received in the sale of assets or merger by
holders of Common Stock for each share of Common Stock held on the effective
date of the transaction (and if such holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding shares of Common Stock); provided, however, that if such
consideration received in the sale of assets or merger was not solely common
stock of the successor corporation or its parent (as defined in Section 424(e)
of the Code), the Board may, with the consent of the successor corporation and
the participant, provide for the consideration to be received upon exercise of
the option to be solely common stock of the successor corporation or its parent
equal in fair market value to the per share consideration received by holders of
Common Stock in the sale of assets or merger.

        19. Amendment or Termination.

            (a) The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in paragraph 18, no
such termination can affect

                                       -8-

<PAGE>

options previously granted, provided that an Offering Period may be terminated
by the Board of Directors on any Exercise Date if the Board determines that the
termination of the Plan is in the best interests of the Company and its
stockholders. Except as provided in paragraph 18, no amendment may make any
change in any option theretofore granted which adversely affects the rights of
any participant. To the extent necessary to comply with Rule 16b-3 or under
Section 423 of the Code (or any successor rule or provision or any other
applicable law or regulation), the Company shall obtain stockholder approval in
such a manner and to such a degree as required.

            (b) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Purchase Periods and/or
Offering Periods, limit the frequency and/or number of changes in the amount
withheld during Purchase Periods and/or Offering Periods, establish the exchange
ratio applicable to amounts withheld in a currency other than U.S. dollars,
permit payroll withholding in excess of the amount designated by a participant
in order to adjust for delays or mistakes in the Company's processing of
properly completed withholding elections, establish reasonable waiting and
adjustment periods and/or accounting and crediting procedures to ensure that
amounts applied toward the purchase of Common Stock for each participant
properly correspond with amounts withheld from the participant's Compensation,
and establish such other limitations or procedures as the Board (or its
committee) determines in its sole discretion advisable which are consistent with
the Plan.

        20. Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        21. Conditions Upon Issuance of Stock. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares of Common Stock pursuant thereto shall comply with all
applicable provisions of law, domestic or foreign, including, without
limitation, the Securities Act of 1933, as amended, the Securities Exchange Act
of 1934, as amended, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the shares may then be listed, and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

        As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

        22. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under paragraph 19.

                                      -9-

<PAGE>

        23. Additional Restrictions of Rule 16b-3. The terms and conditions of
options granted hereunder to, and the purchase of shares by, persons subject to
Section 16 of the Exchange Act shall comply with the applicable provisions of
Rule 16b-3. This Plan shall be deemed to contain, and such options shall
contain, and the shares issued upon exercise thereof shall be subject to, such
additional conditions and restrictions as may be required by Rule 16b-3 to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

        24. Automatic Transfer to Low Price Offering Period. To the extent
permitted by Rule 16b-3 of the Exchange Act, if the Fair Market Value of the
Common Stock on any Exercise Date in an Offering Period is lower than the Fair
Market Value of the Common Stock on the Enrollment Date of such Offering Period,
then all participants in such Offering Period shall be automatically withdrawn
from such Offering Period immediately after the exercise of their options on
such Exercise Date and automatically re-enrolled in the immediately following
Offering Period as of the first day thereof.

                        1993 EMPLOYEE STOCK PURCHASE PLAN

                             SUBSCRIPTION AGREEMENT

_____ Original Application                          Enrollment Date: ___________

_____ Change in Payroll Deduction Rate

_____ Change of Beneficiary(ies)

        1. __________________________ hereby elects to participate in the
Sanmina-SCI Corporation 1993 Employee Stock Purchase Plan (the "Employee Stock
Purchase Plan") and subscribes to purchase shares of the Company's Common Stock
in accordance with this Subscription Agreement and the Employee Stock Purchase
Plan.

        2. I hereby authorize payroll deductions from each paycheck in the
amount of ____% of my Compensation on each payday (not to exceed 10%) during the
Offering Period in accordance with the Stock Purchase Plan. (Please note that no
fractional percentages are permitted.)

        3. I understand that said payroll deductions shall be accumulated for
the purchase of shares of Common Stock at the applicable Purchase Price
determined in accordance with the Employee Stock Purchase Plan. I understand
that if I do not withdraw from an Offering Period, any accumulated payroll
deductions will be used to automatically exercise my option.

        4. I have received a copy of the complete "Sanmina-SCI Corporation 1993
Employee Stock Purchase Plan." I understand that my participation in the
Employee Stock Purchase Plan is in all respects subject to the terms of the
Plan. I understand that the grant of the option by the Company under this
Subscription Agreement is subject to obtaining shareholder approval of the
Employee Stock Purchase Plan.

        5. Shares purchased for me under the Employee Stock Purchase Plan should
be issued in the name(s) of (employee and/or spouse only):_____________________.

        6. I understand that if I dispose of any shares of Common Stock received
by me pursuant to the Plan within 2 years after the Enrollment Date (the first
day of the Offering Period during which I purchased such shares of Common Stock)
or within 1 year after the Exercise Date (the date I purchased such shares of
Common Stock), I will be treated for federal income tax purposes as having
received ordinary income at the time of such disposition in an amount equal to
the excess of the fair market value of the shares of Common Stock at the time
such shares of Common Stock were delivered to me over the price which I paid for
the shares of Common Stock. I HEREBY AGREE TO

<PAGE>

NOTIFY THE COMPANY IN WRITING WITHIN 30 DAYS AFTER THE DATE OF ANY DISPOSITION
OF MY SHARES OF COMMON STOCK AND I WILL MAKE ADEQUATE PROVISION FOR FEDERAL,
STATE OR OTHER TAX WITHHOLDING OBLIGATIONS, IF ANY, WHICH ARISE UPON THE
DISPOSITION OF THE COMMON STOCK. The Company may, but will not be obligated to,
withhold from my compensation the amount necessary to meet any applicable
withholding obligation including any withholding necessary to make available to
the Company any tax deductions or benefits attributable to sale or early
disposition of Common Stock by me. If I dispose of such shares of Common Stock
at any time after the expiration of the 1-year and 2-year holding periods
described above, I understand that I will be treated for federal income tax
purposes as having received income only at the time of such disposition, and
that such income will be taxed as ordinary income only to the extent of an
amount equal to the lesser of (1) the excess of the fair market value of the
shares of Common Stock at the time of such disposition over the purchase price
which I paid for the shares of Common Stock, or (2) 15% of the fair market value
of the shares of Common Stock on the first day of the Offering Period. The
remainder of the gain, if any, recognized on such disposition will be taxed as
capital gain. I UNDERSTAND THAT THIS TAX SUMMARY IS ONLY A SUMMARY AND IS
SUBJECT TO CHANGE.

        7. I hereby agree to be bound by the terms of the Employee Stock
Purchase Plan. The effectiveness of this Subscription Agreement is dependent
upon my eligibility to participate in the Employee Stock Purchase Plan.

        8. In the event of my death, I hereby designate the following as my
beneficiary(ies) to receive all payments and shares of Common Stock due me under
the Employee Stock Purchase Plan:
