STOCK OPTION AGREEMENT

     This Stock Option Agreement (this  "Agreement") is made and entered into as
of November  22,  1999,  between  The DII Group,  Inc.,  a Delaware  corporation
("Company"), and Flextronics International Ltd., a Singapore company ("Parent").
Capitalized  terms used in this  Agreement but not defined herein shall have the
meanings ascribed to such terms in the Merger Agreement (as defined below).

                                    RECITALS

     A. Concurrently with the execution and delivery of this Agreement, Company,
Parent and Slalom Acquisition  Corp., a Delaware  corporation and a wholly owned
subsidiary of Parent ("Merger Sub"),  are entering into an Agreement and Plan of
Merger (the "Merger  Agreement"),  that provides,  among other things,  upon the
terms and  subject to the  conditions  thereof,  for Company and Parent to enter
into a business combination transaction (the "Merger").

     B. As a  condition  to  Parent's  willingness  to  enter  into  the  Merger
Agreement, Parent has required that Company agree, and Company has so agreed, to
grant to Parent an option to acquire  shares of Company  Common Stock  ("Company
Shares"), upon the terms and subject to the conditions set forth herein.

     In  consideration  of  the  foregoing  and  of  the  mutual  covenants  and
agreements  set forth herein and in the Merger  Agreement and for other good and
valuable   consideration,   the  receipt  and   adequacy  of  which  are  hereby
acknowledged, the parties agree as follows:

     1. Grant of Option.  Company hereby grants to Parent an irrevocable  option
(the  "Option"),  exercisable  following the occurrence of an Exercise Event (as
defined in Section  2(a)),  to acquire up to a number of Company Shares equal to
19.9% of the shares of Company  Common  Stock issued and  outstanding  as of the
date, if any,  upon which an Exercise  Notice (as defined in Section 2(b) below)
shall have been delivered (the "Option  Shares"),  in the manner set forth below
by paying  cash at a price of $65.406  per share  (the  "Exercise  Price").  The
Option  shall not be  transferable  except to the Company  pursuant to Section 8
below.

     2. Exercise of Option; Maximum Proceeds

     (a) For all purposes of this Agreement,  an "Exercise Event" shall mean any
of (i) the occurrence of a Company  Triggering Event (as such term is defined in
the Merger  Agreement) other than any event under clause (vii) of the definition
of Company Triggering Event, (ii) a public announcement of an Option Acquisition
Proposal  (as defined  below)  shall have been made prior to the date the Merger
Agreement is terminated  pursuant to the terms thereof (the "Merger  Termination
Date") and the  occurrence  of one or more of the following on or after the date
of the announcement of such Option Acquisition Proposal:  (1) the requisite vote
of the  stockholders of Company in favor of the Merger  Agreement and the Merger
shall not have been obtained at the Company  Stockholders' Meeting (as such term
is defined in the Merger  Agreement);  (2) a tender offer or exchange  offer for
15% or more of the  outstanding  shares of Company  Common Stock shall have been
commenced  (other than by Parent or an affiliate of Parent);  (3) for any reason
Company shall have failed to call and hold the Company





Stockholders'  Meeting by the Outside Date (as defined in the Merger Agreement);
or (4)  Company  shall have  failed to take all  actions  necessary  to hold the
Company Stockholders'  Meeting as promptly as practicable,  and in any event (to
the  extent   permissible  under  applicable  law)  within  45  days  after  the
declaration  of  effectiveness  of  the   Registration   Statement,   (iii)  the
acquisition  by any person  (other than  Parent) or "group"  (as  defined  under
Section 13(d) of the Exchange Act and the rules and  regulations  thereunder) of
beneficial  ownership of 25% or more of the total outstanding  voting securities
of the  Company  or any of its  subsidiaries,  or  (iv)  the  commencement  of a
solicitation  within the meaning of Rule  14a-1(l) by any person or entity other
than Parent or its Board of Directors  (or any person or entity acting on behalf
of  Parent or its  Board of  Directors)  seeking  to alter  the  composition  of
Company's  Board  of  Directors.   For  purposes  of  this  Agreement,   "Option
Acquisition  Proposal"  shall mean any offer or proposal (other than an offer or
proposal  by  Parent)   relating  to  any   transaction  or  series  of  related
transactions  involving:  (A) any purchase  from Company or  acquisition  by any
person or "group" (as defined  under  Section  13(d) of the Exchange Act and the
rules  and  regulations  thereunder)  of more than a 10%  interest  in the total
outstanding  voting  securities  of  Company or any of its  subsidiaries  or any
tender offer or exchange offer that if consummated would result in any person or
"group" (as defined  under  Section  13(d) of the Exchange Act and the rules and
regulations thereunder) beneficially owning 10% or more of the total outstanding
voting  securities  of  Company  or  any  of its  subsidiaries  or  any  merger,
consolidation,  business  combination or similar transaction  involving Company;
(B) any sale, lease, exchange,  transfer, license, acquisition or disposition of
more than 10% of the assets of Company  (other  than sales of  inventory  in the
ordinary course of business); or (C) any liquidation or dissolution of Company.

     (b) Parent may deliver to Company a written  notice (an "Exercise  Notice")
specifying  that it wishes to exercise and close a purchase of Option  Shares at
any time following the  occurrence,  prior to  termination of the Option,  of an
Exercise  Event and  specifying  the total number of Option  Shares it wishes to
acquire.  Unless such Exercise  Notice is withdrawn by Parent,  the closing of a
purchase of Option Shares (a "Closing")  specified in such Exercise Notice shall
take  place  at the  principal  offices  of  Company  upon  such  date as may be
designated by Parent in writing.

     (c) The  Option  shall  terminate  upon  the  earliest  to occur of (i) the
Effective  Time  (as  such  term  is  defined  in the  Merger  Agreement),  (ii)
termination of the Merger Agreement other than pursuant to Section 7.1(b),  (d),
(f) or (h) thereof,  (iii) 14 months  following  the  termination  of the Merger
Agreement  pursuant  to  Section  7.1(b),  (d),  (f) or (h),  and (iv) 14 months
following the first occurrence of an Exercise Event; provided,  however, that if
the Option is  exercisable  but cannot be exercised by reason of any  applicable
government  order or because the waiting  period  related to the issuance of the
Option  Shares under the HSR Act shall not have expired or been  terminated,  or
because any other condition to closing has not been  satisfied,  then the Option
shall not  terminate  until the tenth  business  day after  such  impediment  to
exercise  shall have been  removed or shall have become final and not subject to
appeal.

     (d) If Parent at any time,  whether  before or after receipt of any Company
Termination  Fee pursuant to Section  7.3(b) of the Merger  Agreement,  receives
proceeds in connection  with any sales or other  dispositions  of this Option or
Option  Shares  (including  on surrender  of this Option to Company  pursuant to
Section 8 hereof or by selling Option Shares to


                                      -2-



Company  pursuant to Section 6(f) or Section 9 hereof),  plus any  dividends (or
equivalent  distributions under Section 7(a) hereof) received by Parent declared
on Option Shares,  less the Exercise  Price  multiplied by the number of Company
Shares  purchased by Parent pursuant to the Option,  which,  taken together with
any Company  Termination  Fee paid or payable  pursuant to Section 7.3(b) of the
Merger  Agreement,  exceeds  three and  one-half  percent  (3.5%) of the Company
Equity Value (as defined  below),  then all proceeds to Parent in excess of such
sum shall be promptly remitted in cash by Parent to Company. For the purposes of
this Agreement,  "Company Equity Value" means the product of the average closing
price of Company  Common Stock on the Nasdaq  National  Market over the five (5)
trading days prior to the Closing  with respect to the first  exercise by Parent
of the Option,  and the sum of: (A) all shares of Company  Common Stock that are
outstanding  as of the close of business on the date  immediately  preceding the
Closing  with  respect to the first  exercise by Parent of the  Option;  (B) all
shares of Company Common Stock issuable upon conversion of all shares of capital
stock that,  at the time of the Closing  with  respect to the first  exercise by
Parent of the Option,  is convertible  into shares of Company Common Stock;  and
(C) all shares of Company Common Stock  issuable upon  conversion of all options
and warrants to acquire Company Common Stock that are  outstanding,  at the time
of the Closing with respect to the first exercise by Parent of the Option (other
than pursuant to this Agreement).

     3. Conditions to Closing.  The obligation of Company to issue Option Shares
to Parent  hereunder is subject to the  conditions  that (a) any waiting  period
under the HSR Act  applicable  to the  issuance of the Option  Shares  hereunder
shall have expired or been  terminated;  (b) all material  consents,  approvals,
orders or authorizations of, or registrations, declarations or filings with, any
Governmental  Entity,  if any,  required in connection  with the issuance of the
Option  Shares  hereunder  shall have been obtained or made, as the case may be;
and (c) no  preliminary  or permanent  injunction or other order by any court of
competent jurisdiction  prohibiting or otherwise restraining such issuance shall
be in effect.  It is understood  and agreed that at any time during which Parent
shall be entitled to deliver to Company an Exercise Notice, the parties will use
their  respective  reasonable  efforts to satisfy all conditions to Closing,  so
that a Closing may take place as promptly as practicable.

     4.  Closing.  At any  Closing,  Company  shall  deliver  to Parent a single
certificate  in  definitive  form  representing  the  number of  Company  Shares
designated by Parent in its Exercise Notice consistent with this Agreement, such
certificate  to be  registered  in the name of Parent and to bear the legend set
forth in Section 9 hereof,  against delivery of payment by Parent to the Company
of the aggregate  purchase  price for the Company Shares so designated and being
purchased  by  delivery  of a certified  check,  bank check or wire  transfer of
immediately available funds.

     5.  Representations  and  Warranties  of Company.  Company  represents  and
warrants to Parent that (a) Company is a  corporation  duly  organized,  validly
existing  and in good  standing  under the laws of the State of Delaware and has
the corporate  power and authority to enter into this Agreement and to carry out
its obligations  hereunder;  (b) the execution and delivery of this Agreement by
Company and consummation by Company of the transactions contemplated hereby have
been duly  authorized by all necessary  corporate  action on the part of Company
and no other  corporate  proceedings  on the part of Company  are  necessary  to
authorize this Agreement


                                      -3-



or any of the transactions contemplated hereby; (c) this Agreement has been duly
executed and  delivered by Company and  constitutes  a legal,  valid and binding
obligation of Company and,  assuming this Agreement  constitutes a legal,  valid
and binding  obligation of Parent, is enforceable  against Company in accordance
with its terms,  except as enforceability may be limited by bankruptcy and other
similar laws affecting the rights of creditors  generally and general principles
of equity;  (d)  except for any  filings,  authorizations,  approvals  or orders
required under the HSR Act and any required  filings of under state  securities,
or "blue sky" laws,  Company has taken all necessary  corporate and other action
to authorize and reserve for issuance and to permit it to issue upon exercise of
the Option,  and at all times from the date hereof until the  termination of the
Option will have reserved for issuance,  a sufficient number of unissued Company
Shares for  Parent to  exercise  the Option in full and will take all  necessary
corporate or other action to authorize  and reserve for issuance all  additional
Company  Shares or other  securities  which may be issuable  pursuant to Section
7(a) upon exercise of the Option, all of which, upon their issuance and delivery
in accordance  with the terms of this Agreement and payment  therefor by Parent,
will be validly issued,  fully paid and nonassessable;  (e) upon delivery of the
Company  Shares and any other  securities to Parent upon exercise of the Option,
Parent will acquire such Company  Shares or other  securities  free and clear of
all claims, liens,  charges,  encumbrances and security interests of any kind or
nature  whatsoever,  excluding  those  imposed by Parent;  (f) the execution and
delivery  of this  Agreement  by Company  do not,  and the  performance  of this
Agreement by the Company will not, (i) violate the Certificate of  Incorporation
or  Bylaws  of the  Company,  (ii)  conflict  with or  violate  any  law,  rule,
regulation,  judgment,  decree or order  applicable to the Company or any of its
subsidiaries or by which they or any of their respective  properties is bound or
affected 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 rise to any right of termination,  amendment,  acceleration or cancellation
of, or result in the creation of a material lien or  encumbrance on any material
property  or assets of  Company  or any of its  subsidiaries  pursuant  to,  any
material contract,  agreement,  instrument or obligation to which Company or any
of its subsidiaries is a party or by which Company or any of its subsidiaries or
any of their material  property is bound or affected;  and (g) the execution and
delivery  of this  Agreement  by Company  do not,  and the  performance  of this
Agreement by Company will not, require any consent,  approval,  authorization or
permit of, or filing with, or notification to, any Governmental  Entity,  except
pursuant  to  applicable  state  securities  or blue sky laws and the HSR Act or
applicable corresponding laws of any foreign jurisdiction.

     6. Registration Rights

     (a) Following the termination of the Merger  Agreement,  Parent  (sometimes
referred  to herein as the  "Holder")  may by  written  notice (a  "Registration
Notice") to Company (the "Registrant")  request the Registrant to register under
the Securities Act all or any part of the shares acquired by the Holder pursuant
to this  Agreement  (such shares  requested to be  registered  the  "Registrable
Securities")  in order to permit the sale or other  disposition  of such  shares
pursuant to a bona fide firm  commitment  underwritten  public offering in which
the Holder and the  underwriters  shall  effect as wide a  distribution  of such
Registrable  Securities as is reasonably  practicable (a "Permitted  Offering");
provided,  however, that any such Registration Notice must relate to a number of
shares  equal to at least 2% of the  outstanding  shares of Common  Stock of the
Registrant on a fully diluted basis and that any rights to require  registration
hereunder  shall


                                      -4-



terminate  with  respect to any shares that may be sold  pursuant to Rule 144(k)
under the  Securities Act or at such time as all of the  Registrable  Securities
may be sold in any three month period  pursuant to Rule 144 under the Securities
Act.

     (b) The Registrant shall use all reasonable  efforts to effect, as promptly
as  practicable,  the  registration  under the Securities Act of the Registrable
Securities  requested to be registered  in the  Registration  Notice;  provided,
however,  that (i) the Holder shall not be entitled to more than an aggregate of
two effective registration  statements hereunder,  and provided further, that if
the Registrant  withdraws a filed  registration  statement at the request of the
Holder  (other  than as the  result of a  material  change  in the  Registrant's
business or the Holder's  learning of new material  information  concerning  the
Registrant),  then  such  filing  shall  be  deemed  to have  been an  effective
registration  for purposes of this clause (i), (ii) the  Registrant  will not be
required to file any such registration  statement during any period of time (not
to exceed 45 days after a Registration Notice in the case of clause (A) below or
90 days after a  Registration  Notice in the case of clauses  (B) and (C) below)
when (A) the  Registrant  is in possession  of material  non-public  information
which it reasonably  believes  would be detrimental to be disclosed at such time
and such information would have to be disclosed if a registration statement were
filed at that time;  (B) the  Registrant is required under the Securities Act to
include  audited  financial  statements  for any  period  in  such  registration
statement and such  financial  statements are not yet available for inclusion in
such registration statement; or (C) the Registrant determines, in its reasonable
judgment, that such registration would interfere with any financing, acquisition
or other material transaction  involving the Registrant and (iii) the Registrant
will not be required  to maintain  the  effectiveness  of any such  registration
statement for a period greater than 90 days. If  consummation of the sale of any
Registrable  Securities  pursuant  to a  registration  hereunder  does not occur
within  180 days  after  the  filing  with the SEC of the  initial  registration
statement  therefor,  the provisions of this Section 6 shall again be applicable
to any proposed registration. The Registrant shall use all reasonable efforts to
cause any  Registrable  Securities  registered  pursuant to this Section 6 to be
qualified for sale under the  securities or blue sky laws of such  jurisdictions
as the Holder may  reasonably  request and shall continue such  registration  or
qualification  in effect in such  jurisdictions  until  the  Holder  has sold or
otherwise  disposed  of all  of  the  securities  subject  to  the  registration
statement;  provided,  however,  that the  Registrant  shall not be  required to
qualify to do  business  in, or consent  to general  service of process  in, any
jurisdiction by reason of this provision.

     (c) The registration  rights set forth in this Section 6 are subject to the
condition  that the Holder shall provide the  Registrant  with such  information
with respect to the Holder's Registrable  Securities,  the plan for distribution
thereof,  and such  other  information  with  respect  to the  Holder as, in the
reasonable  judgment of counsel for the  Registrant,  is necessary to enable the
Registrant to include in a registration statement all material facts required to
be disclosed with respect to a registration  thereunder,  including the identity
of the Holder and the Holder's plan of distribution.

     (d) A  registration  effected under this Section 6 shall be effected at the
Registrant's expense,  except for underwriting discounts and commissions and the
fees and  expenses of counsel to the Holder,  and the  Registrant  shall use all
reasonable efforts to provide to the underwriters such documentation  (including
certificates,  opinions of counsel and "comfort"


                                      -5-



letters from auditors) as are customary in connection with  underwritten  public
offerings and as such  underwriters may reasonably  require.  In connection with
any  registration,  the  Holder  and  the  Registrant  agree  to  enter  into an
underwriting  agreement  reasonably  acceptable to each such party,  in form and
substance  customary  for  transactions  of  this  type  with  the  underwriters
participating in such offering.

     (e) Indemnification

          (i) The Registrant  will  indemnify the Holder,  each of its directors
     and officers and each person who controls the Holder  within the meaning of
     Section 15 of the Securities Act, and each  underwriter of the Registrant's
     securities,  with respect to any registration,  qualification or compliance
     which has been effected  pursuant to this Agreement,  against all expenses,
     claims,  losses,  damages or liabilities  (or actions in respect  thereof),
     including  any of the foregoing  incurred in settlement of any  litigation,
     commenced or  threatened,  arising out of or based on any untrue  statement
     (or  alleged  untrue  statement)  of  a  material  fact  contained  in  any
     registration statement, prospectus, offering circular or other document, or
     any amendment or  supplement  thereto,  incident to any such  registration,
     qualification or compliance, or based on any omission (or alleged omission)
     to state therein a material fact required to be stated therein or necessary
     to make the statements therein, in light of the circumstances in which they
     were made, not  misleading,  or any violation by the Registrant of any rule
     or  regulation  promulgated  under the  Securities  Act  applicable  to the
     Registrant  in  connection  with any such  registration,  qualification  or
     compliance,  and the Registrant  will reimburse the Holder and, each of its
     directors  and officers and each person who controls the Holder  within the
     meaning of Section 15 of the Securities  Act, and each  underwriter for any
     legal  and any  other  expenses  reasonably  incurred  in  connection  with
     investigating,  preparing  or  defending  any  such  claim,  loss,  damage,
     liability or action; provided that the Registrant will not be liable in any
     such case to the extent that any such claim,  loss,  damage,  liability  or
     expense  arises out of or is based on any untrue  statement  or omission or
     alleged  untrue  statement  or  omission,  made  in  reliance  upon  and in
     conformity  with written  information  furnished to the  Registrant  by the
     Holder or director or officer or controlling person or underwriter  seeking
     indemnification.

          (ii) The Holder will indemnify the  Registrant,  each of its directors
     and officers and each underwriter of the Registrant's securities covered by
     such  registration  statement  and each person who controls the  Registrant
     within the meaning of Section 15 of the Securities Act, against all claims,
     losses, damages and liabilities (or actions in respect thereof),  including
     any of the foregoing incurred in settlement of any litigation, commenced or
     threatened,  arising  out of or based on any untrue  statement  (or alleged
     untrue  statement)  of a material fact  contained in any such  registration
     statement, prospectus, offering circular or other document, or any omission
     (or  alleged  omission)  to state  therein a material  fact  required to be
     stated therein or necessary to make the statements  therein not misleading,
     or any violation by the Holder of any rule or regulation  promulgated under
     the  Securities  Act  applicable to the Holder in connection  with any such
     registration,   qualification   or  compliance,   and  will  reimburse  the
     Registrant, such directors, officers or control persons or underwriters for
     any legal or any other  expenses  reasonably  incurred in  connection  with
     investigating,  preparing  or  defending  any  such  claim,  loss,  damage,
     liability  or action,  in each case to the extent,  but only to the extent,
     that such untrue  statement (or alleged  untrue  statement) or omission (or
     alleged  omission)  is  made in such  registration  statement,


                                      -6-



     prospectus,  offering  circular or other  document in reliance  upon and in
     conformity  with written  information  furnished to the  Registrant  by the
     Holder  expressly  for use  therein;  provided  that in no event  shall any
     indemnity under this Section 6(e) exceed the gross proceeds of the offering
     received by the Holder.

          (iii) Each party entitled to  indemnification  under this Section 6(e)
     (the  "Indemnified  Party")  shall  give  notice to the party  required  to
     provide  indemnification  (the  "Indemnifying  Party")  promptly after such
     Indemnified  Party has actual  knowledge of any claim as to which indemnity
     may be  sought,  and shall  permit  the  Indemnifying  Party to assume  the
     defense of any such claim or any litigation resulting  therefrom,  provided
     that counsel for the  Indemnifying  Party, who shall conduct the defense of
     such claim or litigation, shall be approved by the Indemnified Party (whose
     approval shall not unreasonably be withheld), and the Indemnified Party may
     participate  in such defense at such party's  expense;  provided,  however,
     that the Indemnifying Party shall pay such expense if representation of the
     Indemnified  Party by counsel retained by the  Indemnifying  Party would be
     inappropriate  due to actual or potential  differing  interests between the
     Indemnified  Party and any other party  represented by such counsel in such
     proceeding,  and provided further that the failure of any Indemnified Party
     to give notice as provided herein shall not relieve the Indemnifying  Party
     of its obligations  under this Section 6(e) unless the failure to give such
     notice is materially  prejudicial to the  Indemnifying  Party's  ability to
     defend such action. No Indemnifying Party, in the defense of any such claim
     or litigation  shall,  except with the consent of each  Indemnified  Party,
     consent to entry of any  judgment or enter into any  settlement  which does
     not include as an unconditional  term thereof the giving by the claimant or
     plaintiff  to such  Indemnified  Party of a release  from all  liability in
     respect  to such  claim  or  litigation.  No  Indemnifying  Party  shall be
     required to indemnify any Indemnified  Party with respect to any settlement
     entered into without such  Indemnifying  Party's prior consent (which shall
     not be unreasonably withheld).

     (f) Purchase in Lieu of  Registration.  Notwithstanding  anything herein to
the contrary, following delivery of a Registration Notice, Company will have the
option,  exercisable by written  notice  delivered to the Holder within ten (10)
business days after Company's receipt of a Registration  Notice,  irrevocably to
agree to purchase all or any part of the Registrable  Securities covered by such
Registration  Notice,  for cash at per share  price  equal to the average of the
closing sale prices of Company  Common Stock on the Nasdaq  National  Market for
the ten (10) trading days  immediately  preceding  the date of the  Registration
Notice.  Any purchase of Registrable  Securities by Company  hereunder will take
place at a closing to be held at the principal  executive  offices of Company or
its  counsel  at any  reasonable  date and time  designated  by  Company  in its
purchase notice,  within ten (10) business days following  delivery of Company's
purchase notice, or at such other place and time as Company and the Holder shall
agree, and the purchase price shall be paid in immediately available funds.

     7. Adjustment Upon Changes in Capitalization; Rights Plans

     (a) In the  event of any  change in the  Company  Shares by reason of stock
dividends,  stock splits, reverse stock splits, mergers (other than the Merger),
recapitalizations,  combinations, exchanges of shares and the like, the type and
number of shares or  securities  subject to the Option  and the  Exercise  Price
shall be  adjusted  appropriately,  and  proper  provision


                                      -7-



shall be made in the agreements  governing such transaction so that Parent shall
receive,  upon  exercise of the Option,  the number and class of shares or other
securities or property that Parent would have received in respect of the Company
Shares if the Option had been exercised  immediately  prior to such event or the
record date therefor, as applicable.

     (b) Prior to such time as the Option is  terminated,  and at any time after
the Option is exercised (in whole or in part, if at all),  the Company shall not
(i) adopt (or permit the adoption of) a  shareholders  rights plan that contains
provisions for the distribution or exercise of rights  thereunder as a result of
Parent or any affiliate or transferee  being the  beneficial  owner of shares of
the Company by virtue of the Option being  exercisable  or having been exercised
(or as a result of beneficially  owning shares issuable in respect of any Option
Shares),  or (ii) take any other  action which would  prevent or disable  Parent
from  exercising its rights under this Agreement or enjoying the full rights and
privileges possessed by other holders of Company Common Stock generally.

     8.  Surrender of Option.  If, at any time prior to the  termination  of the
Option,  any person or "group" (as defined  under  Section 13(d) of the Exchange
Act and the  rules and  regulations  thereunder)  (an  "Acquiring  Person")  (a)
becomes  the  beneficial  owner  of  more  than  a 50%  interest  in  the  total
outstanding voting securities of Company or any of its subsidiaries or (b) shall
have  entered into an agreement  with  Company  for, or shall have  effected,  a
merger,  consolidation,  business  combination or similar transaction  involving
Company,  or any sale,  lease (other than in the ordinary  course of  business),
exchange,  transfer,  license  (other than in the ordinary  course of business),
acquisition  or  disposition  of more than 50% of the  assets of  Company,  then
Parent  may,  at its sole option and upon  Parent's  written  request to Company
prior to the  termination  of the  Option,  surrender  the  Option to Company in
exchange for the payment by Company to Parent in immediately  available funds of
an amount equal to the product of: (x) the excess, if any, of (i) the greater of
(A) the highest price per share paid by the  Acquiring  Person for any shares of
Company Common Stock in such transaction  (or, if there is no readily  available
per share price in such transaction,  the aggregate  consideration paid or to be
paid by the  Acquiring  Person in such  transaction,  divided  by the  aggregate
number of shares of Company  Common Stock  acquired by the  Acquiring  Person in
such  transaction  (the  value  of  any  consideration  other  than  cash  to be
determined,  in the case of consideration  with a readily  ascertainable  market
value, by reference to such market value and, in any case where the market value
of the consideration is not so ascertainable, by agreement in good faith between
Parent and  Company)) or (B) the highest  closing  sale price of Company  Common
Stock on the Nasdaq  National  Market during the 20 trading days ending with the
trading  day  immediately  preceding  the  date of such  request  over  (ii) the
Exercise Price,  multiplied by (y) the total number of Option Shares as to which
the Option has not theretofore  been  exercised.  Upon the delivery by Parent to
Company of a surrender  request,  each party shall take all actions necessary to
consummate  such  surrender  transaction  as  expeditiously  as  possible.  Upon
exercise of its right to  surrender  the Option or any portion  thereof and full
payment  therefor to Parent  pursuant  to this  Section 8, any and all rights of
Parent  with  respect  to the  portion  of the  Option so  surrendered  shall be
terminated.

     9.  Restrictions  on Transfer;  Right of First Refusal.  Prior to the fifth
anniversary  of the date  hereof  (the  "Expiration  Date"),  Parent  shall  not
directly or indirectly, by operation of law


                                      -8-



or otherwise,  sell,  assign,  pledge,  or otherwise  dispose of or transfer any
Option Shares,  other than (a) to Company,  (b) to an affiliate or subsidiary of
Parent,  (c)  pursuant  to a  Permitted  Offering  (as  defined  above),  (d) in
"broker's  transactions"  or to a "market  maker",  as such terms are defined in
Rule 144 under the  Securities  Act, (e) to secure loans to Parent or guarantees
of loans to any affiliate of Parent,  or (f) in accordance  with this Section 9.
At any time after the first  occurrence  of an  Exercise  Event and prior to the
fifth  anniversary of the date hereof,  if Parent shall desire to sell,  assign,
transfer  or  otherwise  dispose  of all or any of the  Option  Shares  acquired
pursuant to this  Agreement,  other than as permitted by clauses (a) through (e)
of the preceding sentence,  it shall give Company written notice of the proposed
transaction,  identifying the proposed transferee and setting forth the terms of
the  proposed  transaction.  Such  notice  shall be deemed an offer by Parent to
Company to purchase all, but not less than all of the Option  Shares  covered by
such notice,  which may be accepted within five (5) business days of receipt, on
the same terms and conditions and at the same price at which Parent is proposing
to transfer  such Option  Shares to such  transferee.  The  purchase of any such
shares by Company shall be settled  within five (5) business days of the date of
the  acceptance of the offer and the purchase price shall be paid in immediately
available  funds.  In the event of the failure or refusal of Company to purchase
all the Option Shares covered by Parent's  notice,  Parent may sell all, but not
less than all, of such Option Shares to the proposed  transferee at no less than
the price  specified and on terms no more favorable to the transferee than those
set  forth in  Parent's  notice  to  Company,  provided  that  such sale must be
completed  within ninety (90) days of the receipt by Company of Parent's  notice
of its proposed transfer. In addition, prior to any transfer of Option Shares by
Parent,  other than any transfer to Company or a transfer  pursuant to Section 6
hereof,  Parent  shall,  if requested  by Company,  deliver to Company a written
opinion of counsel  reasonably  satisfactory  to Company to the effect that such
transfer may be effected without  registration  under the Securities Act and any
applicable state securities laws.

     10. No Distribution;  Restrictive  Legends.  Parent represents and warrants
that the Option and any Option  Shares  purchased  by it  hereunder is being and
will  be  acquired  by it  without  a  view  to  any  distribution  thereof  and
acknowledges  that it may not sell or offer to sell the  Option  and any  Option
Shares other than in a transaction registered under the Securities Act or exempt
from registration thereunder. Each certificate representing Option Shares issued
to Parent  hereunder  (other  than  certificates  representing  shares sold in a
registered  public  offering  pursuant  to Section 6) shall  include a legend in
substantially the following form:

     THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  AND MAY BE REOFFERED OR SOLD
     ONLY  IF SO  REGISTERED  OR IF  AN  EXEMPTION  FROM  SUCH  REGISTRATION  IS
     AVAILABLE.

     11. Listing and HSR Filing. The Company,  upon the request of Parent, shall
promptly  file an  application  to list the Company  Shares to be acquired  upon
exercise of the Option for quotation on the Nasdaq National Market and shall use
its  reasonable   efforts  to  obtain  approval  of  such  listing  as  soon  as
practicable.  Promptly  after the date hereof,  each of the parties hereto shall
promptly file with the Federal Trade  Commission  and the Antitrust  Division of
the United States Department of Justice all required premerger  notification and
report forms and other


                                      -9-



documents  and  exhibits  required  to be filed  under the HSR Act to permit the
acquisition of the Company Shares subject to the Option at the earliest possible
date.

     12. Binding  Effect.  This Agreement shall be binding upon and inure to the
benefit of the parties  hereto and their  respective  successors  and  permitted
assigns. Nothing contained in this Agreement, express or implied, is intended to
confer  upon any person  other  than the  parties  hereto  and their  respective
successors and permitted assigns any rights or remedies of any nature whatsoever
by reason of this Agreement.

     13. Specific  Performance.  The parties recognize and agree that if for any
reason any of the  provisions of this  Agreement are not performed in accordance
with their specific terms or are otherwise  breached,  immediate and irreparable
harm or injury would be caused for which money  damages would not be an adequate
remedy.  Accordingly,  each party agrees that in addition to other  remedies the
other party shall be entitled to an  injunction  restraining  any  violation  or
threatened violation of the provisions of this Agreement.  In the event that any
action shall be brought in equity to enforce the  provisions  of the  Agreement,
neither party will allege, and each party hereby waives the defense,  that there
is an adequate remedy at law.

     14. Entire  Agreement.  This Agreement and the Merger Agreement  (including
the appendices and exhibits thereto) constitute the entire agreement between the
parties with respect to the subject  matter hereof and supersede all other prior
agreements and  understandings,  both written and oral, between the parties with
respect to the subject matter hereof.

     15.  Further  Assurances.  Each party will  execute  and  deliver  all such
further  documents and  instruments  and take all such further  action as may be
necessary in order to consummate  as promptly as  practicable  the  transactions
contemplated hereby.

     16. Severability.  In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal,  void or  unenforceable,  the  remainder of this  Agreement  will
continue in full force and effect and the application of such provision to other
persons or  circumstances  will be  interpreted  so as  reasonably to effect the
intent of the parties hereto.  The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve,  to the extent  possible,  the  economic,  business and other
purposes of such void or unenforceable provision.

     17.  Notices.  All notices and other  communications  hereunder shall be in
writing  and shall be deemed  given if  delivered  personally  or by  commercial
delivery service, or sent via telecopy (receipt confirmed) to the parties at the
following  addresses or telecopy  numbers (or at such other  address or telecopy
numbers for a party as shall be specified by like notice):
