Acquisition Sub, Inc., a Massachusetts corporation and a wholly owned subsidiary
of Parent ("Merger Sub") and Interleaf,  and subject to the conditions set forth
therein (including  approval by the stockholders of Interleaf),  Merger Sub will
be merged with and into Interleaf (the  "Merger"),  with each share of Interleaf
Common Stock being  converted  into the right to receive 0.3465 shares of common
stock, par value $.0001 per share, of BroadVision  ("BroadVision  Common Stock")
(as  adjusted  for  any  stock  split,  stock  dividend,  reverse  stock  split,
reclassification,  recapitalization or other similar transaction) (the "Exchange
Ratio").  The  description   contained  in  this  Item  3  of  the  transactions
contemplated  by the  Reorganization  Agreement  is qualified in its entirety by
reference to the full text of the Reorganization  Agreement,  a copy of which is
attached to this Schedule 13D as Exhibit 99.1.

     To facilitate the  consummation of the Merger (as defined in Item 4 below),
certain  stockholders  of Interleaf  have entered  into Voting  Agreements  with

Agreement (as defined in Item 4 below) with BroadVision.

ITEM 4. PURPOSE OF TRANSACTION

     (a) - (b) As  described  in Item 3 above,  this  statement  relates  to the
merger of Merger Sub, a wholly-owned  subsidiary of  BroadVision,  with and into

<PAGE>
CUSIP No. 458729209               SCHEDULE 13D                      Page 4 of 13


the separate  existence of Merger Sub will cease and Interleaf  will continue as
the  surviving  corporation  and as a  wholly-owned  subsidiary  of  BroadVision
("Surviving   Corporation").   The  officers  and  directors  of  the  Surviving
Corporation  after  the  Effective  Time  shall  be as  mutually  determined  by
Interleaf and  BroadVision  prior to the  Effective  Time and shall serve as the
officers  and  directors of the  Surviving  Corporation  until their  respective
successors are elected and qualified or duly appointed,  as the case may be. The
Articles  of  Organization  of the  Surviving  Corporation  shall be amended and
restated as of the Effective Time to conform to the Articles of  Organization of
Merger  Sub as in effect  immediately  prior to the  Effective  Time;  provided,
however,  that  at the  Effective  Time  the  Articles  of  Organization  of the
Surviving  Corporation  shall  be  amended  so that  the  name of the  Surviving
Corporation  shall be Interleaf,  Inc. The Bylaws of the  Surviving  Corporation
shall be amended and restated as of the Effective  Time to conform to the Bylaws
of Merger Sub as in effect immediately prior to the Effective Time.

     MERGER CONSIDERATION. In connection with the Merger, holders of outstanding
Interleaf  Common  Stock will  receive,  in exchange for each share of Interleaf
Common  Stock  held by them,  0.3465  shares  of  BroadVision  Common  Stock (as
adjusted   for  any  stock  split,   stock   dividend,   reverse   stock  split,
reclassification,  recapitalization  or other similar  transaction)  (i.e.,  the
Exchange Ratio). A warrant to purchase Interleaf Common Stock shall be converted
into the right to receive,  upon the exercise  thereof,  the number of shares of
BroadVision  Common Stock that the holder  thereof  would have received had such
holder  exercised the warrant  immediately  prior to the Effective  Time and the
shares of  Interleaf  Common Stock that would have been held by such holder upon
such exercise were  converted into  BroadVision  Common Stock and the holders of
warrants  to  purchase  Interleaf  Series  D  Preferred  Stock,  to  the  extent
outstanding immediately prior to the Effective Time, shall be converted into the
right to receive, upon the exercise thereof, the number of shares of BroadVision
Common  Stock  that the  holder  thereof  would have  received  had such  holder
exercised  such warrants and elected to convert the shares of Series D Preferred
Stock  issuable  upon such  exercise,  in each  case,  immediately  prior to the
Effective  Time,  and the shares of Interleaf  Common Stock that would have been
held by such  holder upon such  exercise  and  conversion  were  converted  into
BroadVision  Common  Stock In  addition,  BroadVision  will  assume all  options
outstanding under Interleaf's 1993 Stock Option Plan, 1993 Director Stock Option
Plan,  1994  Employee  Stock  Option  Plan,  1997 Key Man Stock  Option Plan and
Agreement,  and 1998 Key Man Stock Option Plan and Agreement. In accordance with
the  terms of the  Reorganization  Agreement,  BroadVision  and  Interleaf  will
mutually agree as to the treatment of  Interleaf's  1998 Employee Stock Purchase
Plan. If the Merger is consummated,  Interleaf Common Stock will be deregistered
under the Exchange Act and delisted from the Nasdaq National Market.

     REPRESENTATIONS,   WARRANTIES,   COVENANTS  AND  CLOSING  CONDITIONS.   The
Reorganization  Agreement contains customary  representations  and warranties on
the part of Interleaf and  BroadVision,  and the  consummation  of the Merger is
subject to customary closing conditions, including, without limitation, approval
by the stockholders of Interleaf,  regulatory  approval and the occurrence of no
material  adverse effect with respect to a party. The  Reorganization  Agreement
also contains  covenants  regarding the activities of Interleaf and  BroadVision
prior  to  the  earlier  of  the  Effective  Time  and  the  termination  of the
Reorganization  Agreement.  Interleaf  has agreed to conduct its business in the
ordinary course and in a commercially  reasonable manner. In addition,  a number
of corporate  actions by Interleaf  during the period pending the closing of the
Merger   require   BroadVision's   approval,   including   borrowings,   capital
expenditures and stock option grants above specified  minimums.  BroadVision has
agreed to conduct its  business  in the  ordinary  course and in a  commercially
reasonable manner.

     TERMINATION OF THE MERGER AGREEMENT.  The  Reorganization  Agreement may be
terminated prior to the Effective Time,  whether before or after approval of the
Merger by the stockholders of BroadVision and the stockholders of Interleaf: (i)
by  mutual  written  consent  of the  Boards of  Directors  of  BroadVision  and
Interleaf;  (ii)  subject  to  certain  exceptions,  by  either  BroadVision  or
Interleaf if the Merger shall not have been  consummated by July 31, 2000; (iii)
by  either  BroadVision  or  Interleaf  in  connection  with  certain  legal  or
governmental actions having the effect of permanently restraining,  enjoining or
otherwise  prohibiting  the  Merger;  (iv)  subject to certain  limitations,  by
BroadVision or Interleaf if the Interleaf Stockholders' Meeting shall have
<PAGE>

been held and the  Reorganization  Agreement  and the Merger shall not have been
approved by the necessary vote of the Interleaf  shareholders;  (v) by Interleaf
if (at any  time  prior  to the  adoption  and  approval  of the  Reorganization
Agreement  and  approval  of  the  Merger  by  the  Interleaf   shareholders)  a
"Triggering  Event" (as  defined  in the  Reorganization  Agreement)  shall have
occurred;  (vi) subject to certain  limitations,  by BroadVision or Interleaf if
the BroadVision  Stockholders'  Meeting shall have been held and the issuance of
BroadVision  Common  Stock in the  Merger  shall not have been  approved  by the
necessary  vote  of  the  BroadVision  stockholders;  (vii)  by  BroadVision  if
Interleaf's representations and warranties in the Reorganization Agreement shall
be or become  materially  inaccurate or if any of  Interleaf's  covenants in the
Reorganization  Agreement  shall  have been  breached  and not cured  within the
period required by the Merger Agreement; or (viii) by Interleaf if BroadVision's
representations  and  warranties  in the  Reorganization  Agreement  shall be or
become  materially  inaccurate  or if  any  of  BroadVision's  covenants  in the
Reorganization  Agreement  shall  have been  breached  and not cured  within the
period required by the Merger Agreement.

     The description  contained in this Item 4 of the transactions  contemplated
by the Reorganization Agreement is qualified in its entirety by reference to the
full text of the Reorganization  Agreement,  a copy of which is attached to this
Schedule 13D as Exhibit 99.1.

     VOTING  AGREEMENTS.  As an  inducement  to  BroadVision  to enter  into the
Reorganization  Agreement,  each of the  officers  and  directors  of  Interleaf
(individually, a "Interleaf Voting Agreement Stockholder" and, collectively, the
"Interleaf Voting Agreement  Stockholders")  has entered into a Voting Agreement
dated as of January 26, 2000 (individually, an "Interleaf Voting Agreement" and,
collectively, the "Interleaf Voting Agreements") with BroadVision. The number of
shares of Interleaf  Common Stock  beneficially  owned by each of the  Interleaf
Voting Agreement  Stockholders is set forth on Schedule II to this Schedule 13D.
The Interleaf Voting Agreement  Stockholders,  who beneficially own an aggregate
of 589,176  outstanding  shares of Interleaf Common Stock (assuming the issuance
of exercisable  options as of January 6, 2000 by the Interleaf  Voting Agreement
Stockholders) (representing approximately 4.2% of the shares of Interleaf Common
Stock as of January 6, 2000) have agreed  that,  prior to the  Expiration  Date,
they will vote their shares of Interleaf  Common Stock in favor of: (i) approval
of the Merger; (ii) approval and adoption of the Reorganization  Agreement;  and
(iii) each of the other actions  contemplated by the  Reorganization  Agreement.
The Interleaf Voting Agreement  Stockholders  have also delivered to BroadVision
irrevocable  proxies with respect to the matters covered by the Interleaf Voting
Agreements. In addition, subject to certain de minimis exceptions, the Interleaf
Voting  Agreement  Stockholders  have agreed not to transfer any  securities  of
Interleaf  owned by them  unless  and  until  the  proposed  transferee  of such
Interleaf  securities  shall have (i) executed a  counterpart  of the  Interleaf
Voting Agreement and an irrevocable proxy and (ii) agreed to hold such Interleaf
securities  subject to all of the terms and  provisions of the Interleaf  Voting
Agreement. BroadVision did not pay any additional consideration to any Interleaf
Voting  Agreement  Stockholders in connection with the execution and delivery of
the Interleaf Voting Agreements. The description contained in this Item 4 of the
transactions contemplated by the Interleaf Voting Agreements is qualified in its
entirety  by  reference  to the  full  text  of the  form  of  Interleaf  Voting
Agreement, a copy of which is attached to this Schedule 13D as Exhibit 99.2.

     STOCK OPTION AGREEMENT.  Also as an inducement to BroadVision to enter into
the  Reorganization  Agreement,  BroadVision and Interleaf  entered into a Stock
Option  Agreement  dated January 26, 2000 (the "Option  Agreement")  pursuant to
which  Interleaf  granted  BroadVision  the right under  certain  conditions  to
purchase up to 2,688,572  shares of Interleaf Common Stock (the "Option Shares")
at a purchase  price  equal to the  lesser of (a)  $52.69,  or (b) the  Exchange
Ratio,  multiplied  by the  average  of the  closing  sales  price of a share of
BroadVision  Common Stock as reported on the Nasdaq  National  Market for the 20
consecutive  trading days ending on the second  trading day preceding the notice
date. Subject to certain conditions,  the option granted in the Option Agreement
may be  exercised,  in whole or in part,  on any one  occasion,  if an "Exercise
Event" (as defined in the  Reorganization  Agreement)  has occurred.  The Option
becomes  exercisable  for this  reason,  the  Option  shall  terminate  upon the
earliest to occur of: (i) the date on which the Merger  becomes  effective;  (b)
the date on which the Reorganization Agreement is terminated pursuant to Section
8.1  thereof,  if an Exercise  Event (as  defined in Section  4(b) of the Option
Agreement)  shall not have  occurred on or prior to such date;  or (c) the first
anniversary of the date six months after the date on which BroadVision  receives
written  notice from  Interleaf  of the  occurrence  of an  Exercise  Event (the
"Exercise  Event Notice  Date");  provided,  however,  that if an Exercise Event
occurs, and if, by reason of any

<PAGE>

CUSIP No. 458729209               SCHEDULE 13D                      Page 6 of 13

applicable Legal Requirement, order, judgment, decree or other legal impediment,
the Option cannot be exercised on the first  anniversary  of the Exercise  Event
Notice Date, then the Termination  Date shall be extended until the date 30 days
after the date on which such  impediment is removed.  The rights of  BroadVision
and the  obligations  of  Interleaf  set forth in Sections 7, 8, 9 and 10 of the
Option Agreement shall not terminate on the Termination  Date, but shall survive
beyond the Termination Date as provided in those Sections.

     In addition, BroadVision has agreed that in the event receives net proceeds
in connection with any sale or other  disposition of the Option or Option Shares
(including,  without limitation, any amounts received by BroadVision pursuant to
Sections 7, 8 or 9) which, together with any proceeds received by BroadVision in
connection  with  any  prior  such  sale  or   disposition,   any  dividends  or
distributions  received by  BroadVision on any Option Shares and any amount paid
to  BroadVision  pursuant  to Sections  8.3(b) and 8.3(c) of the  Reorganization
Agreement prior thereto or thereafter, are in excess of the Threshold Amount (as
defined herein), then all net proceeds to BroadVision in excess of the Threshold
Amount shall be remitted to the Company promptly  following receipt thereof.  As
used herein,  "Threshold  Amount"  shall mean the amount equal to the greater of
(i)  $35,000,000  or (ii) the  product of (A) 200,000 and (B) the average of the
closing  sales price of a share of  BroadVision  Common Stock as reported on the
Nasdaq National Market for the five consecutive trading days ending on the first
trading day preceding the first occurrence of an Exercise Event.

     (c) Not applicable.

     (d) If the Merger is  consummated,  Interleaf  will  become a  wholly-owned
subsidiary of BroadVision and BroadVision will  subsequently  determine the size
and  membership  of the Board of  Directors  of  Interleaf  and the  officers of
Interleaf.

     (e) None,  other  than a change  in the  number  of  outstanding  shares of
Interleaf Common Stock as contemplated by the Reorganization Agreement.

     (f) Upon  consummation of the Merger,  Interleaf will become a wholly-owned
subsidiary of BroadVision.

     (g) Upon  consummation  of the  Merger,  the  Articles of  Organization  of
Interleaf will be amended and restated in a form satisfactory to BroadVision.

     (h) Upon consummation of the Merger,  the Interleaf Common Stock will cease
to be quoted on any quotation system or exchange.

     (i) Upon consummation of the Merger, the Interleaf Common Stock will become
eligible for  termination of  registration  pursuant to Section  12(g)(4) of the
Exchange Act.

     (j) Other than as described  above,  BroadVision  currently  has no plan or
proposal  which relates to, or may result in, any of the matters listed in Items
4(a) -(i) of Schedule 13D  (although  BroadVision  reserves the right to develop
such plans).

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

     (a) - (b) As a result of the Interleaf Voting  Agreements,  BroadVision has
shared power to vote an aggregate of 3,277,748  shares of Interleaf Common Stock
(assuming the issuance of  exercisable  options as of January 6, 2000 subject to
the Interleaf Voting  Agreements ) for the limited purposes  described in Item 4
above. As a result of the Option Agreement  granted to BroadVision,  BroadVision
may be deemed to be the beneficial  owner of an additional  2,688,572  shares of
Interleaf  Common Stock (assuming  exercise of the Option as described in Item 4
above). In the aggregate,  such shares (representing a total of 3,277,748 shares
of Interleaf  Common Stock  (assuming the issuance of exercisable  options as of
January 6, 2000 by the Interleaf Voting Agreement Stockholders)) would represent
approximately  19.7% of the shares of Interleaf  Common Stock  outstanding as of
January 6, 2000 after giving effect to the exercise of the Option.

     To  BroadVision's  knowledge,  no  shares  of  Interleaf  Common  Stock are
beneficially  owned by any of the  persons  named in Schedule I, except for such

                 AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

     THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION  ("Agreement") is made
and entered  into as of January 26,  2000,  by and among:  BROADVISION,  INC., a
Delaware corporation ("Parent"); INFINITI ACQUISITION SUB, INC., a Massachusetts
corporation  and a  wholly  owned  subsidiary  of  Parent  ("Merger  Sub");  and
INTERLEAF,   INC.,  a  Massachusetts   corporation  (the   "Company").   Certain
capitalized terms used in this Agreement are defined in Exhibit A.

                                    RECITALS

     A. Parent,  Merger Sub and the Company  intend to effect a merger of Merger
Sub into the Company (the  "Merger") in accordance  with this  Agreement and the
Massachusetts  Business  Corporation Law (the "MBCL").  Upon consummation of the
Merger,  Merger Sub will cease to exist,  and the  Company  will become a wholly
owned subsidiary of Parent.

     B. It is  intended  that the Merger  qualify  as a tax-free  reorganization
within the meaning of Section  368(a) of the Internal  Revenue Code of 1986,  as
amended (the "Code").  For financial reporting purposes,  it is anticipated that
the Merger be accounted for as a purchase.

     C. The respective boards of directors of Parent, Merger Sub and the Company
have approved this Agreement and approved the Merger.

     D. In order to induce Parent to enter into this Agreement and to consummate
the Merger,  concurrently  with the execution and delivery of this Agreement the
Company is entering into a stock option agreement with Parent (the "Stock Option
Agreement"),  pursuant  to which the  Company  has  granted to Parent an option,
exercisable under the  circumstances  specified  therein,  to purchase shares of
Company Common Stock.

                                    AGREEMENT

Unless otherwise determined by Parent prior to the Effective Time:

               (a) the Articles of  Organization  of the  Surviving  Corporation

               (c) the  directors  and  officers  of the  Surviving  Corporation
immediately after the Effective Time shall be the respective individuals who are
directors and officers of Merger Sub immediately prior to the Effective Time.

          1.5 Conversion of Shares.

               (a) At the  Effective  Time,  by virtue of the Merger and without
any  further  action on the part of  Parent,  Merger  Sub,  the  Company  or any
stockholder of the Company:

                    (i) any  shares of  Company  Common  Stock  then held by the
Company or any wholly owned  Subsidiary of the Company (or held in the Company's
treasury)  shall be  canceled  and  retired  and shall  cease to  exist,  and no
consideration shall be delivered in exchange therefor;

                    (ii) any shares of Company Common Stock then held by Parent,
Merger Sub or any other wholly owned  Subsidiary of Parent shall be canceled and
retired and shall cease to exist,  and no  consideration  shall be  delivered in
exchange therefor;

                    (iii)  except as provided in clauses  "(i)" and "(ii)" above
and subject to Sections 1.5(b),  1.5(c) and 1.5(d), each share of Company Common
Stock then outstanding  shall be converted into the right to receive 0.3465 of a
share of Parent Common Stock;

                                        2
<PAGE>
                    (iv) each  share of the  common  stock,  $0.01 par value per
share,  of Merger  Sub then  outstanding  shall be  converted  into one share of
common stock of the Surviving Corporation; and

                    (v) (x) the Finpiave Warrant (as defined in Section 2.3(b)),
to the extent  outstanding  immediately  prior to the Effective  Time,  shall be
converted into the right to receive,  upon the exercise  thereof,  the number of
shares of Parent  Common Stock that the holder  thereof  would have received had
such holder  exercised the Finpiave Warrant  immediately  prior to the Effective
Time and the  shares of Company  Common  Stock that would have been held by such
holder upon such exercise were  converted  into Parent Common Stock  pursuant to
this  Section  1.5; and (y) each of the Series D Warrants (as defined in Section
2.3(b)),  to the extent  outstanding  immediately  prior to the Effective  Time,
shall be converted  into the right to receive,  upon the exercise  thereof,  the
number of shares of Parent  Common  Stock  that the  holder  thereof  would have
received had such holder  exercised such Series D Warrant and elected to convert
the  shares  of Series D (as  defined  in  Section  2.3(b))  issuable  upon such
exercise, in each case,  immediately prior to the Effective Time, and the shares
of Company  Common  Stock that  would  have been held by such  holder  upon such
exercise and conversion were converted into Parent Common Stock pursuant to this
Section 1.5.

The fraction of a share of Parent  Common Stock  specified in clause  "(iii)" of
the  preceding  sentence (as such  fraction may be adjusted in  accordance  with
Section 1.5(b)) is referred to as the "Exchange Ratio."

               (b) If,  between  the date of this  Agreement  and the  Effective
Time, the outstanding  shares of Company Common Stock or Parent Common Stock are
changed into a different number or class of shares by reason of any stock split,
division  or  subdivision  of  shares,  stock  dividend,  reverse  stock  split,
reclassification,  recapitalization  or  other  similar  transaction,  then  the
Exchange Ratio shall be appropriately adjusted.

               (c) If any shares of Company Common Stock outstanding immediately
prior to the Effective Time are unvested or are subject to a repurchase  option,
risk of forfeiture or other  condition  under any  applicable  restricted  stock
purchase  agreement  or other  agreement  with the  Company  or under  which the
Company has any rights,  then,  unless the terms  governing  such Company Common
Stock provide that such restriction, repurchase right or risk of forfeiture will
be automatically waived in connection with the transactions contemplated by this
Agreement,  the shares of Parent Common Stock issued in exchange for such shares
of Company Common Stock will also be unvested and subject to the same repurchase
option, risk of forfeiture or other condition, and the certificates representing
such shares of Parent Common Stock may  accordingly  be marked with  appropriate
legends.

               (d) No  fractional  shares of Parent Common Stock shall be issued
in  connection  with the  Merger,  and no  certificates  or  scrip  for any such
fractional shares shall be issued.  Any holder of Company Common Stock who would
otherwise  be entitled to receive a fraction of a share of Parent  Common  Stock
(after aggregating all fractional shares of Parent Common Stock issuable to such
holder)  shall,  in lieu of such fraction of a share and upon  surrender of such
holder's  Company Stock  Certificate(s)  (as defined in Section 1.6), be paid in
cash the dollar amount  (rounded to the nearest whole cent),  without  interest,
determined by

                                        3
<PAGE>
multiplying such fraction by the closing price of a share of Parent Common Stock
on the Nasdaq National Market on the date the Merger becomes effective.

          1.6 Closing of the Company's  Transfer  Books.  At the Effective Time:
(a) all shares of Company  Common  Stock  outstanding  immediately  prior to the
Effective  Time shall  automatically  be canceled and retired and shall cease to
exist,  and all holders of  certificates  representing  shares of Company Common
Stock that were outstanding  immediately prior to the Effective Time shall cease
to have any rights as  stockholders  of the Company;  and (b) the stock transfer
books of the  Company  shall be closed  with  respect  to all  shares of Company
Common Stock  outstanding  immediately  prior to the Effective  Time. No further
transfer of any such shares of Company  Common Stock shall be made on such stock
transfer books after the Effective  Time. If, after the Effective  Time, a valid
certificate  previously  representing  any  shares of  Company  Common  Stock (a
"Company Stock  Certificate")  is presented to the Exchange Agent (as defined in
Section 1.7) or to the  Surviving  Corporation  or Parent,  such  Company  Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.7.

          1.7 Exchange of Certificates.

               (a) On or  prior  to the  Closing  Date,  Parent  shall  select a
reputable  bank or trust  company to act as  exchange  agent in the Merger  (the
"Exchange Agent").  Promptly after the Effective Time, Parent shall deposit with
the Exchange  Agent (i)  certificates  representing  the shares of Parent Common
Stock  issuable  pursuant to this  Section 1, and (ii) cash  sufficient  to make
payments in lieu of fractional  shares in accordance  with Section  1.5(d).  The
shares of Parent  Common Stock and cash  amounts so deposited  with the Exchange
Agent,  together  with any dividends or  distributions  received by the Exchange
Agent with respect to such shares, are referred to collectively as the "Exchange
Fund."

               (b) As soon as reasonably  practicable  after the Effective Time,
Parent will cause the Exchange  Agent will mail to the record holders of Company
Stock  Certificates (i) a letter of transmittal in customary form and containing
such  provisions  as  Parent  may  reasonably  specify  (including  a  provision
confirming that delivery of Company Stock  Certificates  shall be effected,  and
risk of loss and title to  Company  Stock  Certificates  shall  pass,  only upon
delivery of such Company Stock  Certificates  to the Exchange  Agent),  and (ii)
instructions for use in effecting the surrender of Company Stock Certificates in
exchange for certificates  representing Parent Common Stock. Upon surrender of a
Company Stock  Certificate to the Exchange  Agent for exchange,  together with a
duly  executed  letter  of  transmittal  and  such  other  documents  as  may be
reasonably  required  by the  Exchange  Agent or Parent,  (A) the holder of such
Company Stock  Certificate  shall be entitled to receive in exchange  therefor a
certificate  representing the number of whole shares of Parent Common Stock that
such holder has the right to receive  pursuant to the  provisions of Section 1.5
(and cash in lieu of any fractional  share of Parent Common Stock),  and (B) the
Company Stock Certificate so surrendered shall be canceled. Until surrendered as
contemplated by this Section  1.7(b),  each Company Stock  Certificate  shall be
deemed,  from and after  the  Effective  Time,  to  represent  only the right to
receive shares of Parent Common Stock (and cash in lieu of any fractional  share
of Parent  Common  Stock) as  contemplated  by Section 1. If any  Company  Stock
Certificate  shall have been  lost,  stolen or  destroyed,  Parent  may,  in its
discretion  and as a condition  precedent  to the  issuance  of any  certificate
representing  Parent  Common  Stock,  require the owner of such lost,  stolen or

                                        4
<PAGE>
destroyed Company Stock  Certificate to provide an appropriate  affidavit and to
deliver  a bond (in such sum as  Parent  may  reasonably  direct)  as  indemnity
against any claim that may be made  against the  Exchange  Agent,  Parent or the
Surviving Corporation with respect to such Company Stock Certificate.

               (c) No  dividends  or other  distributions  declared or made with
respect to Parent Common Stock with a record date after the Effective Time shall
be paid to the  holder  of any  unsurrendered  Company  Stock  Certificate  with
respect to the shares of Parent  Common  Stock that such holder has the right to
receive  in  the  Merger  until  such  holder   surrenders  such  Company  Stock
Certificate in accordance with this Section 1.7 (at which time such holder shall
be entitled,  subject to the effect of  applicable  escheat or similar  laws, to
receive all such dividends and distributions, without interest).

               (d) Any portion of the Exchange  Fund that remains  undistributed
to holders of Company Stock Certificates as of the first anniversary of the date
on which the Merger becomes  effective shall be delivered to Parent upon demand,
and  any  holders  of  Company  Stock  Certificates  who  have  not  theretofore
surrendered their Company Stock Certificates in accordance with this Section 1.7
shall thereafter look only to Parent for satisfaction of their claims for Parent
Common Stock,  cash in lieu of fractional  shares of Parent Common Stock and any
dividends or distributions with respect to Parent Common Stock.

               (e)  Each  of  the  Exchange  Agent,  Parent  and  the  Surviving
Corporation  shall be entitled  to deduct and  withhold  from any  consideration
payable or  otherwise  deliverable  pursuant to this  Agreement to any holder or
former  holder of Company  Common  Stock such  amounts as may be  required to be
deducted or withheld  therefrom under the Code or any provision of state,  local
or  foreign  tax law or under any other  applicable  Legal  Requirement.  To the
extent such amounts are so deducted or withheld,  such amounts  shall be treated
for all purposes  under this Agreement as having been paid to the Person to whom
such amounts would otherwise have been paid.

               (f) Neither Parent nor the Surviving  Corporation shall be liable
to any holder or former  holder of Company  Common  Stock or to any other Person
with respect to any shares of Parent Common Stock (or dividends or distributions
with respect thereto), or for any cash amounts, delivered to any public official
pursuant to any applicable  abandoned property law, escheat law or similar Legal
Requirement.

          1.8 Dissenting Shares.

               (a)  Notwithstanding  any  provision  of  this  Agreement  to the
contrary,  the shares of any holder of Company Common Stock who has demanded and
perfected  appraisal rights for such shares in accordance with the MBCL and who,
as of the Effective Time, has not  effectively  withdrawn or lost such appraisal
rights (the  "Dissenting  Shares"),  shall not be converted  into or represent a
right to receive  Parent  Common  Stock  pursuant to Section 1.5, but the holder
thereof shall only be entitled to such rights as are granted by the MBCL.

               (b)  Notwithstanding  the  foregoing,  if any holder of shares of
Company  Common Stock who demands  appraisal of such shares under the MBCL shall
effectively

                                        5
<PAGE>
withdraw the request for appraisal or lose the right to  appraisal,  then, as of
the later of the Effective Time and the occurrence of such event,  such holder's
shares shall  automatically  be converted  into and represent  only the right to
receive  Parent  Common  Stock and cash in lieu of  fractional  shares,  without
interest thereon, upon surrender of the Company Stock Certificates  representing
such shares.

               (c) The  Company  shall  give  Parent  (i)  prompt  notice of any
written demands for appraisal of any shares of Company Common Stock, withdrawals
of such  demands  and any  other  instruments  served  pursuant  to the MBCL and
received by Company,  which relate to any such demand for appraisal and (ii) the
opportunity to participate in all negotiations and proceedings  which take place
prior to the  Effective  Time with  respect to demands for  appraisal  under the
MBCL.  Company shall not,  except with the prior written consent of Parent or as
may be required by applicable law,  voluntarily make any payment with respect to
any demands for  appraisal of Company  Common Stock or offer to settle or settle
any such demands.

          1.9 Tax Consequences.  For federal income tax purposes,  the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code.  The parties to this  Agreement  hereby adopt this Agreement as a "plan of
reorganization"  within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

          1.10 Further  Action.  If, at any time after the Effective  Time,  any
further action is determined by Parent to be necessary or desirable to carry out
the purposes of this  Agreement or to vest the Surviving  Corporation  with full
right,  title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving  Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

(ii) none of the Company  SEC  Documents  contained  any untrue  statement  of a
material fact or omitted to state a material fact required to be stated  therein

financial  statements  may not contain  footnotes  and are subject to normal and
recurring year-end adjustments that will not,  individually or in the aggregate,
be material in amount),  and (iii)  fairly  present the  consolidated  financial

of the Unaudited  Interim Balance Sheet);  and (b) all other assets reflected in
the  books  and  records  of the  Acquired  Corporations  as being  owned by the
Acquired Corporations. All of said assets are owned by the Acquired Corporations
free and clear of any  Encumbrances,  except  for (i) any lien for Taxes not yet

any case or in the  aggregate)  materially  detract from the value of the assets
subject  thereto or  materially  impair the  operations  of any of the  Acquired
Corporations, and (iii) liens described in the Company Disclosure Schedule.

          2.7 Receivables;  Customers.  All existing accounts  receivable of the
Acquired  Corporations  (including  those accounts  receivable  reflected on the
Unaudited  Interim  Balance  Sheet  that have not yet been  collected  and those

collected  in full  when due,  without  any  counterclaim  or set off (net of an
allowance for doubtful  accounts not to exceed $966,000 in the  aggregate).  The
Company  has not  received  any  written  notice  or  other  written  (including
electronic)   communication,   and  has  not  received  any  other  information,
indicating that any customer or other Person accounting for more than 10% of the
gross  revenues  received  by the  Acquired  Corporations  from  the sale of the
Company's BladeRunner and QuickSilver products since the launch of such products
may cease  dealing  with the  Company  or may  otherwise  reduce  the  volume of
business transacted by such Person with the Company below historical levels.

          2.8  Real  Property;  Equipment;  Leasehold.  All  material  items  of
equipment  and  other  tangible  assets  owned  by or  leased  to  the  Acquired
Corporations  are adequate for the uses to which they are being put, are in good
and safe condition and repair (ordinary wear and tear excepted) and are adequate
for the conduct of the  business of the Acquired  Corporations  in the manner in
which such business is currently being conducted.

          2.9 Proprietary Assets.

               (a) Part 2.9(a)(i) of the Company Disclosure Schedule sets forth,
with respect to each  Proprietary  Asset owned by the Acquired  Corporations and
registered with any Governmental Body or for which an application has been filed
with any Governmental  Body, (i) a brief description of such Proprietary  Asset,
and (ii) the names of the jurisdictions  covered by the applicable  registration
or application.  Part 2.9(a)(ii) of the Company Disclosure  Schedule  identifies
and provides a brief  description of all other  Proprietary  Assets owned by the
Acquired  Corporations  that  are  material  to the  business  of  the  Acquired
Corporations. Part 2.9(a)(iii) of the Company Disclosure Schedule identifies and
provides a brief  description  of, and identifies any ongoing royalty or payment
obligations  in excess of $10,000 per quarter with respect to, each  Proprietary
Asset that is licensed or otherwise made available to the Acquired  Corporations
by any Person and is  material  to the  business  of the  Acquired  Corporations
(except for any Proprietary Asset that is licensed to the Acquired  Corporations
under any third party software license generally available to the public or that
was at the time the license was entered into available on substantially  similar
terms to companies  that are similarly  situated),  and  identifies the Contract
under which such Proprietary Asset is being licensed or otherwise made available
to such  Acquired  Corporation.  The Acquired  Corporations  have good and valid
title  to  all of the  Acquired  Corporation  Proprietary  Assets  owned  by the
Acquired  Corporations,  free and clear of all Encumbrances,  except for (i) any
lien for Taxes not yet due and payable, and (ii) minor liens that have arisen in
the  ordinary  course  of  business  and  that  do not  (individually  or in the

                                       11
<PAGE>
aggregate)  materially  detract from the value of the assets subject  thereto or
materially  impair the  operations of either of the Acquired  Corporations.  The
Acquired  Corporations  have a valid right to use, license and otherwise exploit
all  Proprietary  Assets  required to be identified in Part  2.9(a)(iii)  of the
Company  Disclosure  Schedule subject to the terms of any applicable  Contracts.
Except as set forth in Part 2.9(a)(iv) of the Company Disclosure Schedule,  none
of the Acquired  Corporations  has  developed  jointly with any other Person any
Acquired  Corporation  Proprietary Asset that is material to the business of the
Acquired  Corporations  with  respect to which such other Person has any rights.
There is no  Acquired  Corporation  Contract  (with  the  exception  of end user
license  agreements in the form  previously  delivered or made available (at the
offices of Skadden,  Arps,  Slate,  Meagher & Flom LLP or Craig Newfield) by the
Company to Parent)  pursuant  to which any Person has any right  (whether or not
currently  exercisable)  to use,  license  or  otherwise  exploit  any  Acquired
Corporation Proprietary Asset, other than Acquired Corporation Contracts for the
distribution of products of the Acquired Corporations by distributors, resellers
and channel partners.

               (b) The Acquired  Corporations have taken reasonable measures and
precautions  to protect and maintain the  confidentiality,  secrecy and value of
all  material   Acquired   Corporation   Proprietary   Assets  (except  Acquired
Corporation  Proprietary  Assets whose value would be unimpaired by disclosure).
Without  limiting the  generality of the  foregoing,  (i) all current and former
employees of the Acquired  Corporations who are or were involved in, or who have
contributed to, the creation or development of any material Acquired Corporation
Proprietary  Asset have executed and delivered to the Acquired  Corporations  an
agreement  (containing no material exceptions to or exclusions from the scope of
its  coverage)  that is  substantially  identical to the form of  Invention  and
Nondisclosure  Agreement previously delivered by the Company to Parent, and (ii)
all current and former  consultants and independent  contractors to the Acquired
Corporations  who are or were  involved  in,  or who have  contributed  to,  the
creation or development of any material Acquired  Corporation  Proprietary Asset
have executed and delivered to the Company an agreement  (containing no material
exceptions  to  or  exclusions   from  the  scope  of  its  coverage)   that  is
substantially  identical  to one of  the  two  forms  of  Contractor  Agreements
previously  delivered  to  Parent.  No  current  or  former  employee,  officer,
director, stockholder, consultant or independent contractor has any right, claim
or interest in or with respect to any Acquired Corporation Proprietary Asset.

               (c) To the knowledge of the Company:  (i) all patents,  trademark
registrations  currently  used in the  business  of the  Acquired  Corporations,
service  mark  registrations  currently  used in the  business  of the  Acquired
Corporations   and  copyright   registrations   held  by  any  of  the  Acquired
Corporations  are valid,  enforceable and subsisting;  (ii) none of the Acquired
Corporation  Proprietary Assets and no Proprietary Asset that is currently being
developed  by any of the  Acquired  Corporations  (either  by itself or with any
other Person)  infringes,  misappropriates  or conflicts  with any rights in any
Proprietary Asset owned or used by any other Person;  (iii) none of the products
that are or have been designed, created, developed,  assembled,  manufactured or
sold by any of the Acquired  Corporations  is  infringing,  misappropriating  or
making any unlawful or unauthorized  use of any Proprietary  Asset owned or used
by any  other  Person,  and none of such  products  has at any  time  infringed,
misappropriated  or made any  unlawful or  unauthorized  use of, and none of the
Acquired Corporations has received any notice or other communication (in writing
or  otherwise)  of any  actual,  alleged,  possible or  potential  infringement,
misappropriation or unlawful or unauthorized use of, any

                                       12
<PAGE>
Proprietary  Asset owned or used by any other  Person;  (iv) no other  Person is
materially  infringing,  misappropriating or making any unlawful or unauthorized
use of, and no  Proprietary  Asset owned or used by any other Person  materially
infringes or conflicts with, any Acquired Corporation Proprietary Asset.

               (d) The Acquired  Corporation  Proprietary  Assets constitute all
the Proprietary Assets necessary to enable the Acquired  Corporations to conduct
their  business  in the  manner  in which  such  business  has been and is being
conducted.  None  of the  Acquired  Corporations  has  (i)  licensed  any of the
material Acquired  Corporation  Proprietary Assets to any Person on an exclusive
basis, or (ii) entered into any covenant not to compete or Contract limiting its
ability to exploit fully any material Acquired Corporation Proprietary Assets or
to transact business in any market or geographical area or with any Person.

               (e) None of the Acquired  Corporations has disclosed or delivered
to any Person,  or permitted  the  disclosure or delivery to any escrow agent or
other Person,  of any Acquired  Corporation  Source Code. No event has occurred,
and no circumstance or condition  exists,  that (with or without notice or lapse
of time) will, or could  reasonably be expected to, result in the  disclosure or
delivery to any Person of any Acquired Corporation Source Code. Part 2.10(a)(ii)
of the Company  Disclosure  Schedule  identifies each Contract pursuant to which
the Company has deposited or is required to deposit with an  escrowholder or any
other Person any Acquired Corporation Source Code, and further describes whether
the execution of this Agreement or the  consummation of any of the  transactions
contemplated  hereby  could  reasonably  be expected to result in the release or
disclosure of any Acquired Corporation Source Code.

               (f) To the  knowledge of the  Company,  each  computer,  computer
program and other item of software  (whether  installed  on a computer or on any
other piece of equipment,  including  firmware) that is currently used by any of
the Acquired Corporations and material for their internal business operations is
Year 2000 Compliant.  To the knowledge of the Company, each computer program and
other item of software that is currently generally offered for sale or otherwise
made  available to any Person by any of the Acquired  Corporations  is Year 2000
Compliant.  For purposes of this Section  2.9, a computer,  computer  program or
other item of software  shall be deemed to be "Year 2000  Compliant"  only if it
meets the  definition of "Year 2000  Compliant" set forth as of the date of this
Agreement on the Company's web page under the heading "Year 2000 Statement."

               (g) Except  with  respect to  demonstration  or trial  copies and
except for security routines intended to restrict the end-user to use within the
scope of such end-user's license, no product, system, program or software module
designed,  developed,  sold,  licensed or otherwise made available by any of the
Acquired  Corporations  to any Person  contains  any "back  door,"  "time bomb,"
"Trojan horse," "worm," "drop dead device,"  "virus" or other software  routines
or hardware components  designed by or on behalf of any Acquired  Corporation to
permit  unauthorized  access or to disable or erase  software,  hardware or data
without the consent of the user.

                    (ii) any Contract (A) relating to the acquisition, transfer,

Corporations  under any third party software license which is or was at the time
the license was entered into generally available to the public or that is or was
at the time the license was entered  into  available  on  substantially  similar
terms to companies that are similarly situated,  or (2) any Proprietary Asset is
licensed by any of the Acquired  Corporations  to any Person on a  non-exclusive
basis),  or (B) of the type  required to be set forth in Part 2.9 of the Company
Disclosure Schedule;

                    (iii) any Contract that provides for  indemnification of any

                    (vii)  any  other  Contract,  the  breach  of  which  by any
Acquired  Corporation  could  reasonably be expected to have a Material  Adverse

The Company has delivered or made  available  (at the offices of Skadden,  Arps,
Slate,  Meagher & Flom LLP or Craig Newfield) to Parent an accurate and complete
copy of each Acquired Corporation Contract that constitutes a Material Contract.

               (b)  Each  Acquired   Corporation  Contract  that  constitutes  a
Material  Contract is valid and in full force and effect,  and is enforceable in
accordance with its terms,  subject to (i) laws of general application  relating
to  bankruptcy,  insolvency  and the  relief of  debtors,  and (ii) rules of law
governing specific performance, injunctive relief and other equitable remedies.

<PAGE>
               (c) None of the Acquired  Corporations  has violated or breached,
or  committed  any  default  under,  any  Acquired   Corporation  Contract  that
constitutes a Material  Contract,  except for violations,  breaches and defaults
that  have not had and would  not  reasonably  be  expected  to have a  Material
Adverse  Effect on the  Acquired  Corporations;  and,  to the  knowledge  of the
Company,  no other  Person has violated or  breached,  or committed  any default
under, any Acquired  Corporation  Contract that constitutes a Material Contract,
except for  violations,  breaches and  defaults  that have not had and would not
reasonably  be  expected  to have a  Material  Adverse  Effect  on the  Acquired
Corporations.  To the knowledge of the Company,  no event has  occurred,  and no
circumstance or condition exists, that (with or without notice or lapse of time)
will, or would reasonably be expected to, (A) result in a violation or breach of
any of the provisions of any Acquired  Corporation  Contract that  constitutes a
Material  Contract,  (B) give any  Person  the right to  declare  a  default  or
exercise any remedy under any Acquired  Corporation  Contract that constitutes a

Contract  that  constitutes  a Material  Contract,  except in each such case for
defaults, acceleration rights, termination rights and other rights that have not
had and would not  reasonably be expected to have a Material  Adverse  Effect on
the  Acquired  Corporations.  Since  September  30,  1999,  none of the Acquired
Corporations  has  received  any  written  notice  or other  written  (including
electronic)  communication  regarding any actual or possible violation or breach
of, or default  under,  any Acquired  Corporation  Contract  that  constitutes a
Material Contract,  except in each such case for defaults,  acceleration rights,
termination  rights and other rights that have not had and would not  reasonably
be expected to have a Material Adverse Effect on the Acquired Corporations.

          2.11 Sale of Products;  Performance of Services.  Since  September 30,
1999,  no  customer  or other  Person  has  asserted  or  threatened  in writing
(including an electronic  communication)  to assert any claim against any of the

behalf  of any of the  Acquired  Corporations,  or (b) based  upon any  services

Corporations  is, and has at all times since January 1, 1998 been, in compliance
with all applicable Legal Requirements,  except where the failure to comply with
such Legal Requirements has not had and would not reasonably be expected to have
a Material  Adverse  Effect on the Acquired  Corporations.  Since  September 30,
1999, none of the Acquired

                                       15
<PAGE>
Corporations  has  received  any  written  notice  or other  written  (including
electronic)  communication  from any Governmental Body or other Person regarding

               (a)   The   Acquired    Corporations    hold   all   Governmental
Authorizations  necessary to enable the Acquired  Corporations  to conduct their
respective businesses in the manner in which such businesses are currently being
conducted, except where the failure to hold such Governmental Authorizations has
not had and would not  reasonably be expected to have a Material  Adverse Effect
on the Acquired Corporations. All such Governmental Authorizations are valid and
in full force and effect.  Each Acquired  Corporation is, and at all times since

requirements of such Governmental Authorizations, except where the failure to be
in   compliance   with  the  terms  and   requirements   of  such   Governmental
Authorizations  has not had and  would  not  reasonably  be  expected  to have a
Material Adverse Effect on the Acquired Corporations.  Since September 30, 1999,
none of the  Acquired  Corporations  has  received  any written  notice or other
written  (including   electronic)   communication  from  any  Governmental  Body

                                       16
<PAGE>
accordance  with  generally  accepted  accounting   principles.   Each  Acquired
Corporation  will  establish,  in the ordinary course of business and consistent
with  its  past  practices,  reserves  in  accordance  with  generally  accepted
accounting principles for the payment of all Taxes for the period from September
30, 1999 through the Closing Date.

               (c) No Acquired Corporation Return is currently under examination
or audit by any  Governmental  Body.  No extension  or waiver of the  limitation
period  applicable to any of the Acquired  Corporation  Returns has been granted
(by the  Company  or any  other  Person)  that is still in  effect,  and no such
extension or waiver has been  requested  from any Acquired  Corporation  that is
still in effect.

               (d) No claim or Legal  Proceeding is pending or, to the knowledge
of the Company,  has been  threatened in writing  against or with respect to any
Acquired  Corporation  in respect of any material Tax.  There are no unsatisfied
liabilities for material Taxes (including liabilities for interest, additions to
tax and penalties  thereon and related  expenses)  with respect to any notice of
deficiency or similar document received by any Acquired Corporation with respect
to any material Tax (other than  liabilities  for Taxes  asserted under any such
notice of deficiency or similar document which are being contested in good faith
by the Acquired  Corporations  and with respect to which  reserves in accordance
with generally accepted accounting  principles for payment have been established
on the Unaudited Interim Balance Sheet).  None of the Acquired  Corporations has
been,  and none of the Acquired  Corporations  will be,  required to include any
material  adjustment in taxable  income for any Tax period (or portion  thereof)
pursuant  to Section  481 or 263A of the Code (or any  comparable  provision  of
state or foreign Tax laws) as a result of transactions or events  occurring,  or
accounting methods employed, prior to the Closing.

               (e) The Company has delivered to Parent all documents relevant to
all agreements,  Plans, arrangements or other Contracts covering any employee or
independent  contractor or former  employee or independent  contractor of any of
the  Acquired   Corporations   that,   considered   individually  or  considered
collectively  with any  other  such  Contracts,  will,  or could  reasonably  be
expected to, give rise  directly or indirectly to the payment of any amount that
would not be deductible  pursuant to Section 280G or Section 162 of the Code (or
any comparable  provision  under state Tax laws).  With respect to the documents
provided pursuant to the preceding sentence,  the Company has provided to Parent
the following  information:  (i) the name of each person who the Company expects
to be a "disqualified  individual"  within the meaning of Section 280G(c) of the
Code; and (ii) the "base amount" within the meaning of Section 280G(b)(3) of the
Code for each such individual.

               (f) None of the  Acquired  Corporations  is, or has ever been,  a
party to or bound by any Tax indemnity  agreement,  Tax sharing  agreement,  Tax
allocation agreement or similar Contract.

arrangement (collectively, the "Plans") sponsored, maintained, contributed to or
required  to be  contributed  to by any of the  Acquired  Corporations  for  the
benefit of any current or former  employee of any of the Acquired  Corporations.
None  of  the  Acquired   Corporations  is  obligated  to  make  any  severance,
termination or similar  payment to any current or former employee or director in
excess of six months of such employee's or director's salary.

               (b) None of the  Acquired  Corporations  maintains,  sponsors  or
contributes  to, and none of the  Acquired  Corporations  has at any time in the
past maintained,  sponsored or contributed to, any employee pension benefit plan
(as defined in Section 3(2) of the Employee  Retirement  Income  Security Act of
1974, as amended  ("ERISA"),  or any similar pension benefit plan under the laws
of any  foreign  jurisdiction,  whether  or not  excluded  from  coverage  under
specific  Titles or  Subtitles  of ERISA for the benefit of  employees or former
employees of any of the Acquired Corporations (a "Pension Plan").

               (c) With respect to each Plan,  the Company has delivered or made
available (at the offices of Skadden,  Arps, Slate,  Meagher & Flom LLP or Craig
Newfield) to Parent:  (i) an accurate and complete copy of such Plan  (including
all  amendments  thereto);  (ii) an  accurate  and  complete  copy of the annual
report,  if required  under  ERISA,  with  respect to such Plan for the last two
years;  (iii) an accurate  and  complete  copy of the most recent  summary  plan
description,  together with each summary of material modifications,  if required
under ERISA,  with respect to such Plan,  (iv) if such Plan is funded  through a
trust or any third party funding  vehicle,  an accurate and complete copy of the
trust or other funding agreement (including all amendments thereto) and accurate

accurate and complete copy of the most recent determination letter received from
the Internal Revenue Service with respect to such Plan (if such Plan is intended
to be qualified under Section 401(a) of the Code).

               (d)  None  of  the  Acquired  Corporations  is or has  ever  been
required to be treated as a single  employer with any other Person under Section
4001(b)(1) of ERISA or Section 414(b),  (c), (m) or (o) of the Code,  except for
the Acquired  Corporations.  None of the Acquired  Corporations  has ever been a
member of an "affiliated  service group" within the meaning of Section 414(m) of
the Code. None of the Plans identified in the Company  Disclosure  Schedule is a
multiemployer  plan (within the meaning of Section 3(37) of ERISA) or subject to
Title IV of ERISA. None of the Acquired Corporations has ever made a complete or
partial withdrawal from a multiemployer plan, as such term is defined in Section
3(37) of ERISA, resulting in "withdrawal  liability," as such term is defined in
Section 4201 of ERISA (without regard to subsequent  reduction or waiver of such
liability under either Section 4207 or 4208 of ERISA).

               (e) None of the Acquired  Corporations has any binding commitment
to create  any  Welfare  Plan or any  Pension  Plan,  or to modify or change any
existing Welfare Plan or Pension Plan (other than to comply with applicable law)
in a manner that would affect any current or former  employee or director of any
of the Acquired Corporations.

               (f) No Plan provides death,  medical or health benefits  (whether
or not insured)  with  respect to any current or former  employee or director of
any of the Acquired

                                       18
<PAGE>
Corporations  after any  termination  of service of such  employee  or  director
(other than benefit  coverage  mandated by applicable  law,  including  coverage
provided pursuant to Section 4980B of the Code).

               (g) Each of the Plans has been operated and  administered  in all
material  respects  in  accordance  with its  terms  and with  applicable  Legal
Requirements,   including   ERISA,   the  Code  and  applicable   foreign  Legal
Requirements.  Part  2.17(g) of the Company  Disclosure  Schedule  lists (i) the
former  employees  of the  Acquired  Corporations  who,  as of the  date of this
Agreement,  have elected  continuation  coverage under Section 4980B of the Code
with  respect  to  themselves  or  their   dependents  and  (ii)  the  qualified
beneficiaries  (within the meaning of Section 4980B(g)(1) of the Code) under the
Plans who, as of the date of this Agreement,  have elected continuation coverage
under Section 4980B of the Code.

               (h) Each of the Plans  intended  to be  qualified  under  Section
401(a)  of the Code has  received  a  favorable  determination  letter  from the
Internal  Revenue  Service,  and nothing has occurred  that could  reasonably be
expected to adversely affect such determination.

               (i)  Neither  the  execution,  delivery  or  performance  of this
Agreement,  nor the consummation of the Merger or any of the other  transactions
contemplated  by this  Agreement,  will result in any bonus,  golden  parachute,
severance or other payment or  obligation  to any current or former  employee or
director of any of the Acquired Corporations (whether or not under any Plan), or
materially  increase the benefits  payable or provided under any Plan, or result
in any  acceleration  of the time of payment  or  vesting of any such  benefits.
Without  limiting the  generality of the  foregoing  (and except as set forth in
Part 2.17(i) of the Company Disclosure Schedule), the consummation of the Merger
will not result in the acceleration of vesting of any unvested Company Options.

               (j) Part 2.17(j) of the Company  Disclosure  Schedule  contains a
list of all salaried  employees of each of the Acquired  Corporations  as of the
date of this Agreement,  and correctly reflects, in all material respects, their
salaries, any other compensation payable to them (including compensation payable
pursuant to bonus,  deferred  compensation  or commission  arrangements),  their
dates of employment and their positions.  None of the Acquired Corporations is a
party to any collective bargaining contract or other Contract with a labor union
involving any of its employees.  To the extent permitted by Legal  Requirements,
all employees of the Acquired Corporations are "at will" employees.

               (k) Part 2.17(k) of the Company  Disclosure  Schedule  identifies
each employee of any of the Acquired  Corporations who is not fully available to
perform work because of disability or other leave.

material respects with all applicable Legal  Requirements and Contracts relating
to employment,  employment practices, wages, bonuses and terms and conditions of
employment, including employee compensation matters.

               (m) Each of the Acquired  Corporations  has good labor relations,
and none of the Acquired  Corporations has any knowledge of any facts indicating
that (i) the

                                       19
<PAGE>
consummation of the Merger or any of the other transactions contemplated by this
Agreement will have a material  adverse effect on the labor  relations of any of
the Acquired  Corporations,  or (ii) any of the employees of any of the Acquired
Corporations  intends  to  terminate  his or her  employment  with the  Acquired
Corporation with which such employee is employeed.

               (n) With  respect to any Plan  maintained  for  employees  of the
Acquired  Corporations  who are  based  outside  of the  United  States  (each a
"Foreign Plan"), if applicable:  (i) the fair market value of the assets of each
funded  Foreign Plan,  the liability of each insurer for any Foreign Plan funded
through  insurance,  or the book reserve  established  for any unfunded  Foreign
Plan,  together  with any accrued  contributions,  is  sufficient  to procure or
provide  for all  accrued  benefit  obligations  under  each such  Foreign  Plan
according to the  actuarial  assumptions  and  valuations  most recently used to
determine   employer   contributions   or  the  accruals  of  employer   benefit
obligations;  and (ii) the consummation of the transactions contemplated by this
Agreement  will  not by  itself  create  or  otherwise  result  in any  material
liability with respect to any Foreign Plan.

          2.18 Environmental  Matters.  Each of the Acquired Corporations (a) is
in compliance in all material respects with all applicable  Environmental  Laws,
and (b) possesses  all permits and other  Governmental  Authorizations  required
under  applicable  Environmental  Laws, and is in compliance  with the terms and
conditions thereof.  None of the Acquired  Corporations has received any written
notice or other written  (including  electronic)  communication,  whether from a
Governmental Body, citizens group, Employee or otherwise,  that alleges that any
of the Acquired  Corporations is not in compliance with any  Environmental  Law,
and,  to the  knowledge  of the  Company,  there are no  circumstances  that may
prevent or interfere  with the  compliance  by any of the Acquired  Corporations
with any Environmental  Law in the future. To the knowledge of the Company,  (i)
all  property  that is leased to,  controlled  by or used by any of the Acquired
Corporations,  and all surface water,  groundwater  and soil  associated with or
adjacent to such property, is free of any material  environmental  contamination
of any nature, (ii) none of the property leased to, controlled by or used by any
of the Acquired Corporations  contains any underground storage tanks,  asbestos,

property  leased to,  controlled by or used by any of the Acquired  Corporations
contains  any septic  tanks in which  process  wastewater  or any  Materials  of
Environmental Concern have been disposed of. To the knowledge of the Company, no
Acquired  Corporation  has ever  sent or  transported,  or  arranged  to send or
transport,  any Materials of Environmental  Concern to a site that,  pursuant to
any  applicable  Environmental  Law,  (1)  has  been  placed  on  the  "National
Priorities  List" of  hazardous  waste sites or any similar  state list,  (2) is
otherwise designated or identified as a potential site for remediation, cleanup,
closure or other environmental  remedial activity,  or (3) is subject to a Legal
Requirement to take "removal" or "remedial" action as detailed in any applicable
Environmental  Law or to make payment for the cost of cleaning up any site. (For
purposes of this Section 2.18 and Section 3.9: (A) "Environmental Law" means any
federal,  state,  local or foreign  Legal  Requirement  relating to pollution or
protection of human health or the environment  (including  ambient air,  surface
water,  ground water, land surface or subsurface  strata),  including any law or
regulation relating to emissions, discharges, releases or threatened releases of
Materials of Environmental  Concern,  or otherwise  relating to the manufacture,
processing,  distribution,  use,  treatment,  storage,  disposal,  transport  or
handling  of  Materials  of  Environmental   Concern;   and  (B)  "Materials  of
Environmental  Concern" include  chemicals,  pollutants,  contaminants,  wastes,
toxic substances,

                                       20

petroleum  and  petroleum  products  and  any  other  substance  that  is now or
hereafter  regulated by any  Environmental  Law or that is otherwise a danger to
health, reproduction or the environment.)

insurance  programs  and  arrangements  relating  to the  business,  assets  and
operations of the Acquired  Corporations  are in full force and effect and, when
taken together, provide adequate insurance coverage for the business, assets and
operations of the Acquired  Corporations  for all risks normally insured against
by a Person carrying on the same businesses as the Acquired Corporations.

          2.20 Transactions  with Affiliates.  Between the date of the Company's
last proxy statement filed with the SEC and the date of this Agreement, no event
has  occurred  that would be required to be reported by the Company  pursuant to
Item 404 of  Regulation  S-K  promulgated  by the SEC.  Part 2.20 of the Company
Disclosure  Schedule  identifies each Person who is (or who may be deemed to be)
an "affiliate"  (as that term is used in Rule 145 under the  Securities  Act) of
the Company as of the date of this Agreement.

          2.21 Legal Proceedings; Orders.

used by any of the Acquired Corporations;  or (ii) that challenges,  or that may
have the effect of preventing, delaying, making illegal or otherwise interfering
with,  the  Merger  or  any of  the  other  transactions  contemplated  by  this
Agreement. To the knowledge of the Company, no event has occurred, and no claim,
dispute or other  condition  or  circumstance  exists that could  reasonably  be
expected to, give rise to or serve as a basis for the  commencement  of any such
Legal Proceeding.

               (b) There is no material  order,  writ,  injunction,  judgment or
decree to which any of the Acquired Corporations,  or any of the assets owned or
used by any of the Acquired  Corporations,  is subject.  To the knowledge of the
Company,  no officer or key  employee  of any of the  Acquired  Corporations  is
subject to any order, writ,  injunction,  judgment or decree that prohibits such
officer or other employee from engaging in or continuing  any conduct,  activity
or practice relating to the business of any of the Acquired Corporations.

<PAGE>
otherwise apply to the Merger,  this Agreement or any of the other  transactions
contemplated  by this Agreement.  This Agreement and the Stock Option  Agreement

against  the  Company in  accordance  with their  terms,  subject to (i) laws of
general  application  relating  to  bankruptcy,  insolvency  and the  relief  of
debtors, and (ii) rules of law governing specific performance, injunctive relief

impair the operations of any of the Acquired Corporations); or

               (f) result in, or increase the  likelihood  of, the disclosure or
delivery to any escrowholder or other Person of any Acquired  Corporation Source
Code, or the transfer of any material asset of any of the Acquired  Corporations
to any Person.

          3.4 Absence of  Changes.  Between  September  30, 1999 and the date of
this Agreement,  there has not been any material adverse change in the business,
financial condition, capitalization,  assets, liabilities, operations or results
of operations of Parent,  and no event has occurred or  circumstance  has arisen
that, in combination with any other events or circumstances, could reasonably be
expected to result in any material  adverse  change in the  business,  financial
condition,  capitalization,   assets,  liabilities,  operations  or  results  of
operations of Parent.

          3.5 Liabilities. Parent does not have any accrued, contingent or other
liabilities  of any  nature,  either  matured  or  unmatured,  except  for:  (a)
liabilities reflected in the Unaudited Parent Interim Balance Sheet or the notes
thereto; (b) normal and recurring current liabilities that have been incurred by
Parent  since  September  30,  1999  in the  ordinary  course  of  business  and
consistent with past practices; or (c) liabilities arising out of this Agreement
and the transactions contemplated herein.

          3.6  Compliance  with  Legal  Requirements.  Parent is, and has at all
times  since  January 1, 1998 been,  in  compliance  with all  applicable  Legal
Requirements,  except  where the failure to comply with such Legal  Requirements
has not had and would not  reasonably  be  expected  to have a Material  Adverse
Effect on Parent.  Since September 30, 1999, Parent has not received any written
notice  or  other  written   (including   electronic)   communication  from  any
Governmental Body or other Person regarding any actual or possible violation of,
or failure to comply with, any Legal Requirement.

          3.7 Tax Matters.

               (a) Each of the material  Tax Returns  required to be filed by or
on behalf of Parent  with any  Governmental  Body with  respect  to any  taxable

or will be filed on or before the applicable due date  (including any extensions
of such due date),  and (ii) has been,  or will be when  filed,  prepared in all
material  respects in compliance  with all applicable  Legal  Requirements.  All
amounts shown on the Parent Returns to be due on or before the Closing Date have
been or will be paid on or before the Closing Date.

               (b) The Unaudited Parent Interim Balance Sheet accrues all actual
and  contingent  liabilities  for Taxes  with  respect  to all  periods  through
September 30, 1999 in accordance with generally accepted accounting principles.

               (c) No claim or Legal  Proceeding is pending or, to the knowledge
of Parent,  has been  threatened in writing against or with respect to Parent in
respect of any material Tax. There are no unsatisfied  liabilities  for material
Taxes  (including  liabilities  for  interest,  additions  to tax and  penalties
thereon  and  related  expenses)  with  respect to any notice of  deficiency  or
similar document received by Parent with respect to any material Tax (other than
liabilities  for Taxes  asserted  under any such notice of deficiency or similar
document  which are being  contested in good faith by Parent and with respect to
which reserves in accordance with generally accepted  accounting  principles for
payment have been established on the Unaudited Parent Interim Balance Sheet).

          3.8 Environmental Matters. Parent (a) is in compliance in all material
respects with all applicable  Environmental  Laws, and (b) possesses all permits
and other Governmental  Authorizations  required under applicable  Environmental
Laws, and is in compliance with the terms and conditions thereof. Parent has not
received   any  written   notice  or  other   written   (including   electronic)
communication,  whether from a Governmental  Body,  citizens group,  Employee or
otherwise,  that alleges that Parent is not in compliance with any Environmental
Law,  and,  to the  knowledge  of Parent,  there are no  circumstances  that may
prevent or interfere with the compliance by Parent with any Environmental Law in
the future.  To the  knowledge of Parent,  (i) all  property  that is leased to,
controlled by or used by Parent,  and all surface  water,  groundwater  and soil
associated  with  or  adjacent  to  such  property,  is  free  of  any  material
environmental  contamination of any nature, (ii) none of the property leased to,
controlled  by or  used  by  Parent  contains  any  underground  storage  tanks,
asbestos,  equipment using PCBs,  underground injection wells, and (iii) none of
the  property  leased to,  controlled  by or used by Parent  contains any septic
tanks in which process wastewater or any Materials of Environmental Concern have
been  disposed  of. To the  knowledge  of  Parent,  Parent  has not ever sent or
transported,  or arranged to send or transport,  any Materials of  Environmental
Concern to a site that,  pursuant to any applicable  Environmental  Law, (1) has
been placed on the "National  Priorities  List" of hazardous  waste sites or any
similar  state list,  (2) is otherwise  designated  or identified as a potential
site for remediation, cleanup, closure or other environmental remedial activity,
or (3) is subject to a Legal  Requirement to take "removal" or "remedial" action
as detailed in any applicable  Environmental Law or to make payment for the cost
of cleaning up any site.

          3.9 Legal Proceedings.  There is no pending Legal Proceeding,  and (to
the  knowledge  of  Parent)  no Person  has  threatened  to  commence  any Legal
Proceeding:  (a) that  involves  Parent  or any of the  assets  owned or used by
Parent;  or (b) that  challenges,  or that may have the  effect  of  preventing,
delaying, making illegal or otherwise interfering with, the Merger or any of the
other transactions  contemplated by this Agreement.  To the knowledge of Parent,
no event has occurred,  and no claim, dispute or other condition or circumstance
exists that could  reasonably  be expected  to, give rise to or serve as a basis
for the commencement of any such Legal Proceeding.

          3.10  Authority;  Binding  Nature of Agreement.  Parent and Merger Sub
have the right,  power and  authority to perform  their  obligations  under this
Agreement  and the Stock  Option  Agreement;  and the  execution,  delivery  and
performance  by Parent  and Merger Sub of this  Agreement  and the Stock  Option
Agreement  have  been duly  authorized  by all  necessary  action on the part of
Parent and Merger Sub and their  respective  boards of  directors.  This and the
Stock Option Agreement  constitute the legal,  valid and binding  obligations of
Parent and Merger Sub,  enforceable  against them in accordance  with its terms,
subject to (a) laws of general  application  relating to bankruptcy,  insolvency
and the relief of debtors, and (b) rules of law governing specific  performance,
injunctive relief and other equitable remedies.

          3.11 No Vote  Required.  No vote of the holders of Parent Common Stock
is required to authorize the Merger.

          3.12 Non-Contravention;  Consents.  Neither the execution and delivery
of this  Agreement by Parent and Merger Sub nor the  consummation  by Parent and
Merger Sub of

                                       26
<PAGE>
the Merger will (a)  conflict  with or result in any breach of any  provision of
the certificate of  incorporation  or bylaws of Parent or Merger Sub, (b) result
in a  default  by Parent or Merger  Sub under any  Contract  to which  Parent or
Merger Sub is a party, except for any default that has not had and will not have
a Material  Adverse Effect on Parent,  or (c) result in a violation by Parent or
Merger Sub of any order, writ, injunction, judgment or decree to which Parent or
Merger Sub is subject,  except for any  violation  that has not had and will not
have a Material  Adverse  Effect on  Parent.  Except as may be  required  by the
Securities Act, the Exchange Act, state securities or "blue sky" laws, the MBCL,
the HSR Act, any foreign  antitrust law or regulation,  the NASD Bylaws (as they
relate to the S-4 Registration Statement and the Prospectus/Proxy Statement) and
the Frankfurt Stock Exchange, Parent is not and will not be required to make any
filing with or give any notice to, or to obtain any Consent from,  any Person in
connection with the execution,  delivery or performance of this Agreement or the
consummation of the Merger.

          3.13  Valid  Issuance.  The  Parent  Common  Stock to be issued in the
Merger will, when issued in accordance with the provisions of this Agreement, be
validly issued, fully paid and nonassessable.

          3.14  Financial  Advisor.  Except for Goldman  Sachs & Co., no broker,
finder or investment banker is entitled to any brokerage,  finder's or other fee
or  commission in  connection  with the Merger or any of the other  transactions
contemplated by this Agreement based upon  arrangements  made by or on behalf of
Parent.

          3.15  Disclosure.  None of the  information  to be  supplied  by or on
behalf of Parent for inclusion in the Form S-4  Registration  Statement will, at
the time the  Form  S-4  Registration  Statement  becomes  effective  under  the
Securities Act, 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  therein,  in the light of the circumstances under which they are
made, not misleading.  None of the information to be supplied by or on behalf of
Parent for  inclusion in the  Prospectus/Proxy  Statement  will, at the time the
Prospectus/Proxy  Statement is mailed to the  stockholders  of the Company or at
the  time  of  the  Company   Stockholders'   Meeting  (or  any  adjournment  or
postponement  thereof),  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  therein,  in the light of the circumstances  under which
they are made, not misleading.  The Prospectus/Proxy Statement will comply as to
form in all material  respects  with the  provisions of the Exchange Act and the
rules  and  regulations  promulgated  by the  SEC  thereunder,  except  that  no
representation  or warranty is made by Parent with respect to statements made or
incorporated by reference  therein based on information  supplied by the Company
for inclusion or incorporation by reference in the Prospectus/Proxy Statement.

representation  or warranty  made by Parent in this  Agreement;  (ii) any event,
condition,  fact or circumstance that occurs, arises or exists after the date of
this  Agreement and that would cause or constitute a material  inaccuracy in any
representation  or  warranty  made by  Parent  in  this  Agreement  if (A)  such
representation  or  warranty  had been  made as of the  time of the  occurrence,
existence or discovery of such event,  condition,  fact or circumstance,  or (B)
such event, condition,  fact or circumstance had occurred,  arisen or existed on
or  prior  to the date of this  Agreement;  (iii)  any  material  breach  of any
covenant  or  obligation  of  Parent  in this  Agreement;  and (iv)  any  event,
condition,  fact or circumstance that would make the timely  satisfaction of any

notification given to the Company pursuant to this Section 4.4(b) shall limit or
otherwise  affect  any  of  the   representations,   warranties,   covenants  or
obligations of Parent contained in this Agreement.

becomes  aware of any  information,  that should be disclosed in an amendment or
supplement  to the  Form  S-4  Registration  Statement  or the  Prospectus/Proxy

cooperate with Parent in filing such  amendment or supplement  with the SEC and,
if appropriate,  in mailing such amendment or supplement to the  stockholders of
the Company.  If any event relating to Parent occurs, or if Parent becomes aware
of any  information,  that should be disclosed in an amendment or  supplement to

Company  Stockholders'  Meeting;  provided,  however,  that Parent  shall not be
required  (i)  to  qualify  to do  business  as a  foreign  corporation  in  any
jurisdiction  in which it is not now qualified or (ii) to file a general consent
to service of process in any jurisdiction.

          5.2 Company Stockholders' Meeting.

               (a) The  Company  shall  take  all  action  necessary  under  all
applicable Legal  Requirements to call, give notice of and hold a meeting of the
holders of Company  Common Stock to vote on the approval of this  Agreement (the
"Company  Stockholders'  Meeting").  The Company  Stockholders' Meeting shall be
held (on a date selected by the Company in consultation with Parent) as promptly
as  practicable  (and in any  event  within  45 days,  so long as such  Form S-4
Registration  Statement  remains  in effect  and not  subject  to any stop order
during such 45-day period) after the Form S-4 Registration Statement is declared
effective  under the  Securities  Act. The Company shall ensure that all proxies
solicited in connection with the Company  Stockholders' Meeting are solicited in
compliance with all applicable Legal Requirements.

               (b)  Subject to Section  5.2(c):  (i) the Proxy  Statement  shall
include a  statement  to the effect that the board of  directors  of the Company
recommends that the Company's  stockholders  vote to adopt this Agreement at the
Company  Stockholders'  Meeting (the  recommendation  of the Company's  board of
directors that the Company's  stockholders  vote to adopt this  Agreement  being
referred to as the "Company Board  Recommendation");  and (ii) the Company Board
Recommendation shall not be withdrawn or modified in a manner adverse to Parent,
and no  resolution  by the board of  directors  of the Company or any  committee
thereof to  withdraw  or modify the  Company  Board  Recommendation  in a manner
adverse to Parent shall be adopted or proposed.

               (c) Notwithstanding anything to the contrary contained in Section
5.2(b),  the Company  Board  Recommendation  may be  withdrawn  or modified in a
manner adverse to Parent if (1) the Company's  board of directors has determined
in compliance with the requirements set forth in Section  4.3(a)(B) to accept an
Acquisition  Proposal that constitutes a Superior Offer, (2) the Company's board
of  directors  determines  in good faith,  after  having  taken into account the
advice of its outside legal counsel,  that the withdrawal or modification of the
Company Board Recommendation is required in order for such board of directors to
comply  with its  fiduciary  obligations  to the  Company's  stockholders  under
applicable  law,  (3) the  Company  Board  Recommendation  is not  withdrawn  or
modified  in a manner  adverse to Parent at any time  within two  business  days
after  Parent  receives  written  notice  from the Company  confirming  that the
Company's board of directors has determined to accept such Superior  Offer,  and
(4)  simultaneously  with the  withdrawal or  modification  of the Company Board
Recommendation, the Company makes the payments called for by Sections 8.3(a) and
8.3(b).

          5.3 Regulatory Approvals.  Each party shall use all reasonable efforts
to file, as soon as practicable  after the date of this Agreement,  all notices,
reports  and  other  documents  required  to be  filed  by such  party  with any
Governmental  Body  with  respect  to the  Merger  and  the  other  transactions
contemplated  by  this   Agreement,   and  to  submit  promptly  any  additional
information  requested  by any such  Governmental  Body.  Without  limiting  the
generality of the  foregoing,  the Company and Parent shall,  promptly after the
date of this Agreement,  prepare and file the  notifications  required under the
HSR Act and any applicable  foreign  antitrust laws or regulations in connection
with the Merger. The Company and Parent shall respond as promptly as practicable
to (i) any inquiries or requests  received from the Federal Trade  Commission or
the Department of Justice for additional  information or documentation  and (ii)
any inquiries or

                                       35
<PAGE>
requests received from any state attorney general,  foreign antitrust  authority
or other Governmental Body in connection with antitrust or related matters. Each
of the Company and Parent  shall (1) give the other party  prompt  notice of the
commencement or threat of commencement of any Legal  Proceeding by or before any
Governmental  Body with  respect to the Merger or any of the other  transactions
contemplated  by this  Agreement,  (2) keep the other  party  informed as to the
status of any such Legal Proceeding or threat, and (3) promptly inform the other
party  of any  communication  to or  from  the  Federal  Trade  Commission,  the
Department  of Justice or any other  Governmental  Body  regarding  the  Merger.
Except  as  may  be  prohibited  by  any  Governmental  Body  or  by  any  Legal
Requirement, the Company and Parent will consult and cooperate with one another,
and will consider in good faith the views of one another, in connection with any
analysis,  appearance,  presentation,  memorandum,  brief, argument,  opinion or
proposal  made or submitted in  connection  with any Legal  Proceeding  under or
relating to the HSR Act or any other foreign, federal or state antitrust or fair
trade law. In addition,  except as may be prohibited by any Governmental Body or
by any Legal  Requirement,  in  connection  with any Legal  Proceeding  under or
relating to the HSR Act or any other foreign, federal or state antitrust or fair
trade law or any other similar Legal Proceeding,  each of the Company and Parent
will permit authorized  Representatives of the other party to be present at each
meeting or conference  relating to any such Legal  Proceeding and to have access
to and be consulted in connection with any document, opinion or proposal made or
submitted to any Governmental Body in connection with any such Legal Proceeding.

          5.4 Stock Options.

               (a) At the  Effective  Time,  all rights with  respect to Company
Common Stock under each Company Option then outstanding  shall be converted into
and become rights with respect to Parent  Common Stock,  and Parent shall assume
each such Company  Option in  accordance  with the terms (as in effect as of the
date of this  Agreement)  of the stock option plan under which it was issued and
the terms of the stock  option  agreement  by which it is evidenced as set forth
herein.  From and after the Effective  Time,  (i) each Company Option assumed by
Parent  may be  exercised  solely for shares of Parent  Common  Stock,  (ii) the
number of shares of Parent  Common  Stock  subject to each such  Company  Option
shall be equal to the number of shares of Company  Common Stock  subject to such
Company  Option  immediately  prior  to the  Effective  Time  multiplied  by the
Exchange  Ratio,  rounding down to the nearest whole share,  (iii) the per share
exercise  price under each such Company Option shall be adjusted by dividing the
per share  exercise  price under such Company  Option by the Exchange  Ratio and
rounding up to the nearest cent and (iv) any  restriction on the exercise of any
such  Company  Option  shall  continue  in full  force and  effect and the term,
exercisability,  vesting  schedule and other  provisions of such Company  Option
shall otherwise remain  unchanged,  except to the extent that any restriction on
exercise,  term,  exercisability,  vesting schedule and other provisions of such
Company  Option are  automatically  waived in connection  with the  transactions
contemplated  by this  Agreement;  provided,  however,  that each Company Option
assumed by Parent in accordance  with this Section  5.4(a) shall,  in accordance
with its terms,  be subject to further  adjustment as appropriate to reflect any
stock  split,   stock   dividend,   reverse   stock   split,   reclassification,
recapitalization or other similar transaction  subsequent to the Effective Time.
Parent  shall  file with the SEC,  no later than 30 days after the date on which
the Merger becomes effective,  a registration  statement on Form S-8 relating to
the shares of Parent Common Stock  issuable with respect to the Company  Options
assumed by Parent in accordance

                                       36
<PAGE>
with this Section 5.4(a).  Notwithstanding any of the foregoing to the contrary,
in lieu of assuming  outstanding  Company Options,  Parent may, at its election,
cause such  outstanding  Company  Options to be replaced by issuing  replacement
stock options in  substitution  therefor  (each,  a "Substitute  Option").  Each
Substitute  Option shall (i) be  exercisable  solely for shares of Parent Common
Stock,  (ii) cover a number of shares of Parent Common Stock equal to the number
of shares of Company  Common Stock covered by the Company Option for which it is
substituted, multiplied by the Exchange Ratio, rounded down to the nearest whole
share,  (iii) have a per share  exercise  price equal to the per share  exercise
price of the Company Option for which it is substituted, divided by the Exchange
Ratio,  rounded  up to the  nearest  whole  cent  and  (iv)  have  substantially
identical  terms as the Company  Option for which it is  substituted  including,
without limitation,  any restriction on the exercise of any such Company Option,
the term, exercisability,  vesting schedule and other provisions of such Company
Option,   except  to  the  extent  that  any  restriction  on  exercise,   term,
exercisability, vesting schedule and other provisions of such Company Option are
automatically  waived in connection with the  transactions  contemplated by this
Agreement;  provided,  however, that each Substituted Option shall be subject to
further  adjustment as appropriate to reflect any stock split,  stock  dividend,
reverse  stock  split,  reclassification,   recapitalization  or  other  similar
transaction subsequent to the Effective Time.

               (b) All  actions  taken by the  Company  and Parent  pursuant  to
Sections 5.4(a) and (b) above with respect to Company Options that are incentive
stock options  within the meaning of Section 422 of the Code shall not adversely
affect the tax status of such Company Options.

               (c) Prior to the  Effective  Time,  the  Company  shall  take all
action that may be necessary  (under the plans pursuant to which Company Options
are  outstanding and otherwise) to effectuate the provisions of this Section 5.4
and to ensure  that,  from and after the  Effective  Time,  holders  of  Company
Options  have no rights  with  respect  thereto  other than  those  specifically
provided in this Section 5.4.

          5.5  Employee  Benefits.  Parent  agrees  that  all  employees  of the
Acquired  Corporations who are employed by Parent, the Surviving  Corporation or
any Subsidiary of the Surviving Corporation immediately after the Effective Time
("Continuing  Employees")  shall be eligible to continue to  participate  in the
Surviving  Corporation's  health and/or welfare benefit plans in accordance with
the terms of such plans,  which plans shall provide benefits not materially less
favorable in the aggregate to those provided to such employees immediately prior
to the Effective Time; provided,  however,  that (a) nothing in this Section 5.5
or elsewhere in this Agreement  shall limit the right of Parent or the Surviving
Corporation to amend or terminate any such health and/or welfare benefit plan at
any time,  and (b) if Parent or the Surviving  Corporation  terminates  any such
health and/or welfare benefit plan, then, subject to any appropriate  transition
period,  the Continuing  Employees  shall be eligible to participate in Parent's
health,   vacation  and  other  non-equity  based  employee  benefit  plans,  to
substantially the same extent as similarly situated employees of Parent. Nothing
in this Section 5.5 or elsewhere in this Agreement  shall be construed to create
a right in any employee to employment with Parent, the Surviving  Corporation or
any other  Subsidiary of the  Surviving  Corporation  and,  subject to any other
binding agreement between an employee and Parent,  the Surviving  Corporation or
any Subsidiary of the Surviving  Corporation,  the employment of each Continuing

                                       37
<PAGE>
Employee shall be "at will" employment.  The Company agrees to take (or cause to
be  taken)  all  actions  necessary  or  appropriate  to  terminate,   effective
immediately  prior to the Effective Time, any employee benefit plan sponsored by
any of the Acquired  Corporations (or in which any of the Acquired  Corporations
participate)  that contains a cash or deferred  arrangement  intended to qualify
under section 401(k) of the Code. To the extent permitted by Legal Requirements,
following  the  Effective  Time,  Continuing  Employees  shall  be  eligible  to
participate in any employee benefit plan sponsored by the Parent that contains a
cash or deferred  arrangement  intended to qualify under  section  401(k) of the
Code to the same  extent  as  other  similarly  situated  employees  of  Parent.
Following the Effective  Time, with respect to each plan in which any Continuing
Employee participates,  for purposes of determining  eligibility to participate,
vesting,  and  entitlement  to benefits,  including for  severance  benefits and
vacation entitlement (but not for accrual of pension benefits), service with the
Acquired  Corporations  (or  predecessor  employers  to the extent the  Acquired
Corporations  provided  past  service  credit)  shall be treated as service with
Parent, the Surviving Corporation or any affiliate of either; provided, however,
that such service shall not be  recognized  to the extent that such  recognition
would  result in a  duplication  of  benefits.  To the extent  permitted  by the
applicable  insurance  carrier,  such  service  also shall apply for purposes of
satisfying any waiting periods,  evidence of insurability  requirements,  or the
application of any preexisting condition limitations. To the extent permitted by
the  applicable  insurance  carrier,  each such plan  shall  waive  pre-existing
condition limitations to the same extent waived under the applicable plan of the
Acquired  Corporation.  To the  extent  permitted  by the  applicable  insurance
carrier, Continuing Employees shall be given credit under the applicable plan of
Parent,  the Surviving  Corporation  or any affiliate of either for amounts paid
under a  corresponding  benefit  plan  during the same  period for  purposes  of
applying  deductibles,  copayments  and  out-of-pocket  maximums  as though such
amounts  had been  paid in  accordance  with the  terms  and  conditions  of the
successor or replacement plan.

          5.6 Indemnification of Officers and Directors.

               (a) All rights to indemnification existing in favor of any Person
who is now, or had been at any time prior to the date of this  Agreement  or who
becomes prior to the Effective  Time, a director and officer of the Company (the
"Indemnified  Persons") for acts and omissions  occurring prior to the Effective
Time, as provided in the  Company's  bylaws (as in effect as of the date of this
Agreement) and as provided in the indemnification agreements between the Company
and said Indemnified  Persons (as in effect as of the date of this Agreement) in
the  forms  disclosed  by the  Company  to  Parent  prior  to the  date  of this
Agreement,  shall  survive  the Merger and shall be  observed  by the  Surviving
Corporation to the fullest extent available under Massachusetts law for a period
of six years from the Effective Time. Parent hereby guarantees the observance of
such rights to indemnification by the Surviving Corporation.

               (b) From the Effective  Time until the third  anniversary  of the
Effective  Time, the Surviving  Corporation  shall  maintain in effect,  for the
benefit of the Indemnified  Persons with respect to acts or omissions  occurring
prior to the Effective  Time,  the existing  policy of directors'  and officers'
liability  insurance  maintained by the Company as of the date of this Agreement
in the  form  disclosed  by the  Company  to  Parent  prior  to the date of this
Agreement (the "Existing  Policy");  provided,  however,  that (i) the Surviving
Corporation  may  substitute  for the  Existing  Policy a policy or  policies of
comparable coverage, and (ii) the

                                       38
<PAGE>
Surviving  Corporation  shall not be  required  to pay annual  premiums  for the
Existing  Policy (or for any  substitute  policies) in excess of $300,000 in the
aggregate.  In the event any future annual  premiums for the Existing Policy (or
any  substitute  policies)  exceeds  $300,000 in the  aggregate,  the  Surviving
Corporation  shall be entitled to reduce the amount of coverage of the  Existing
Policy  (or any  substitute  policies)  to the  amount of  coverage  that can be
obtained for an annual premium equal to $300,000.

               (c) This Section 5.6 shall survive the consummation of the Merger
and is intended to benefit  and may be enforced by the  Indemnified  Persons and
shall  be  binding  on all  successors  and  assigns  of  Parent  and  Surviving
Corporation.

          5.7 Additional Agreements.

               (a) Subject to Section  5.7(b),  Parent and the Company shall use
all reasonable  efforts to take, or cause to be taken, all actions  necessary to
consummate the Merger and make effective the other transactions  contemplated by
this Agreement. Without limiting the generality of the foregoing, but subject to
Section 5.7(b), each party to this Agreement (i) shall make all filings (if any)
and give all  notices  (if any)  required  to be made and given by such party in
connection  with the  Merger  and the other  transactions  contemplated  by this
Agreement, (ii) shall use all reasonable efforts to obtain each Consent (if any)
required  to be  obtained  (pursuant  to any  applicable  Legal  Requirement  or
Contract,  or otherwise)  by such party in connection  with the Merger or any of
the other transactions  contemplated by this Agreement,  and (iii) shall use all
reasonable  efforts to lift any restraint,  injunction or other legal bar to the
Merger.  The Company shall promptly deliver to Parent a copy of each such filing
made,  each such  notice  given and each such  Consent  obtained  by the Company
during the Pre-Closing Period.

               (b)  Notwithstanding  anything to the contrary  contained in this
Agreement,  Parent shall not have any obligation  under this  Agreement:  (i) to
dispose  of or  transfer  or cause  any of its  Subsidiaries  to  dispose  of or
transfer any assets,  or to commit to cause any of the Acquired  Corporations to
dispose of any assets;  (ii) to discontinue or cause any of its  Subsidiaries to
discontinue  offering  any product or service,  or to commit to cause any of the
Acquired  Corporations to discontinue offering any product or service;  (iii) to
license or otherwise make available, or cause any of its Subsidiaries to license
or otherwise make available,  to any Person,  any technology,  software or other
Proprietary  Asset,  or to commit to cause any of the Acquired  Corporations  to
license or otherwise  make available to any Person any  technology,  software or
other Proprietary  Asset; (iv) to hold separate or cause any of its Subsidiaries
to hold  separate any assets or operations  (either  before or after the Closing
Date),  or to commit to cause any of the Acquired  Corporations to hold separate
any assets or  operations;  or (v) to make or cause any of its  Subsidiaries  to
make any commitment (to any Governmental Body or otherwise) regarding its future
operations or the future operations of any of the Acquired Corporations.

          5.8  Disclosure.  Parent and the Company shall consult with each other
before issuing any press release or otherwise  making any public  statement with
respect  to the  Merger or any of the other  transactions  contemplated  by this
Agreement.  Without limiting the generality of the foregoing,  the Company shall
not,  and shall not permit any of its  Representative  to,  make any  disclosure
regarding  the  Merger or any of the  other  transactions  contemplated  by this
Agreement  unless (a) Parent  shall have  approved  such  disclosure  or (b) the
Company shall

                                       39
<PAGE>
reasonably  determine  after  consultation  with outside legal counsel that such
disclosure is required by applicable law.

Registration  Statement,  the Company,  Merger Sub and Parent shall  execute and
deliver to Cooley Godward LLP and to Skadden,  Arps,  Slate,  Meagher & Flom LLP
tax  representation  letters in forms  reasonably  requested  by the  respective
counsels.  Parent,  Merger  Sub and the  Company  shall  each  confirm to Cooley
Godward LLP and to Skadden,  Arps,  Slate,  Meagher & Flom LLP the  accuracy and
completeness  as of  the  Effective  Time  of  the  tax  representation  letters
delivered pursuant to the immediately preceding sentence. Parent and the Company
shall use all  reasonable  efforts prior to and following the Effective  Time to
cause the Merger to qualify as a tax free reorganization under Section 368(a)(1)
of the Code.  Following delivery of the tax  representation  letters pursuant to
the first sentence of this Section 5.9, each of Parent and the Company shall use
its  reasonable  efforts to cause Cooley Godward LLP and Skadden,  Arps,  Slate,
Meagher & Flom LLP, respectively,  to deliver to it a tax opinion satisfying the
requirements of Item 601 of Regulation S-K promulgated under the Securities Act.
In rendering  such  opinions,  each of such counsel shall be entitled to rely on
the tax representation letters referred to in this Section 5.9.

          5.10  Listing  and  Frankfurt  Stock  Exchange.  Parent  shall use all
reasonable  efforts to cause the shares of Parent  Common  Stock being issued in
the Merger to be approved  for listing  (subject to notice of  issuance)  on the
Nasdaq National Market and to obtain the requisite approval for the consummation
of the Merger by the Frankfurt Stock Exchange.

          5.11 Resignation of Officers and Directors.  The Company shall use all
reasonable  efforts to obtain and  deliver to Parent on or prior to the  Closing

consummate the  transactions  contemplated  by this Agreement are subject to the

the Company  contained in this Agreement shall be accurate in all respects as of

               (a) by mutual written consent of Parent and the Company;

               (b) by either  Parent or the Company if the Merger shall not have
     been  consummated  by July 31, 2000 (unless the failure to  consummate  the
     Merger is  attributable  to a failure  on the part of the party  seeking to
     terminate this Agreement to perform any material  obligation required to be
     performed by such party at or prior to the Effective Time);

               by  either  Parent  or  the  Company  if  a  court  of  competent
     jurisdiction  or other  Governmental  Body  shall  have  issued a final and
     nonappealable  order,  decree  or  ruling,  or shall  have  taken any other
     action,  having  the  effect  of  permanently  restraining,   enjoining  or
     otherwise prohibiting the Merger;

               by either Parent or the Company if (i) the Company  Stockholders'
     Meeting  (including any adjournments and postponements  thereof) shall have
     been held and completed and the Company's  stockholders  shall have taken a
     final vote on a proposal to adopt this  Agreement,  and (ii) this Agreement
     shall  not have  been  adopted  at such  meeting  by the  Required  Company
     Stockholder  Vote (and shall not have been  adopted at any  adjournment  or
     postponement  thereof);  provided,  however,  that (A) a party shall not be
     permitted to terminate  this  Agreement  pursuant to this Section 8.1(d) if
     the  failure to obtain  such  stockholder  approval  is  attributable  to a
     failure  on the  part of such  party to  perform  any  material  obligation
     required to be performed by such party at or prior to the  Effective  Time,
     and (B) the Company  shall not be  permitted to  terminate  this  Agreement
     pursuant to this  Section  8.1(d)  unless the  Company  shall have made the
     payment  required to be made to Parent pursuant to Section 8.3(a) and shall
     have paid to Parent  any fee  required  to be paid to Parent  prior to such
     termination pursuant to Section 8.3(c);

               by Parent (at any time prior to the adoption of this Agreement by
     the Required  Company  Stockholder  Vote) if a Triggering  Event shall have
     occurred;

               by  Parent  if  (i)  any  of the  Company's  representations  and
     warranties  contained in this Agreement  shall be inaccurate as of the date
     of this Agreement,  or shall have become inaccurate as of a date subsequent
     to the date of this Agreement (as if made on such  subsequent  date),  such
     that the condition set forth in Section 6.1 would not be satisfied, or (ii)
     any of the Company's  covenants contained in this Agreement shall have been
     breached  such that the  condition  set forth in  Section  6.2 would not be
     satisfied;  provided,  however,  that  if an  inaccuracy  in the  Company's
     representations  and warranties

                                       44
<PAGE>
     or a breach of a covenant  by the Company is curable by the Company and the
     Company is  continuing  to  exercise  all  reasonable  efforts to cure such
     inaccuracy or breach,  then Parent may not terminate this  Agreement  under
     this Section 8.1(f) on account of such inaccuracy or breach;

               by  the  Company  if  (i)  any of  Parent's  representations  and
     warranties  contained in this Agreement  shall be inaccurate as of the date
     of this Agreement,  or shall have become inaccurate as of a date subsequent
     to the date of this Agreement (as if made on such  subsequent  date),  such
     that the condition set forth in Section 7.1 would not be satisfied, or (ii)
     if any of Parent's  covenants  contained in this Agreement  shall have been
     breached  such that the  condition  set forth in  Section  7.2 would not be
     satisfied;   provided,   however,   that  if  an   inaccuracy  in  Parent's
     representations  and  warranties  or a breach  of a  covenant  by Parent is
     curable by Parent and  Parent is  continuing  to  exercise  all  reasonable
     efforts  to cure  such  inaccuracy  or  breach,  then the  Company  may not
     terminate  this  Agreement  under  this  Section  8.1(g) on account of such
     inaccuracy or breach; or

               by the Company if the board of  directors  of the  Company  shall
     have  approved a  Superior  Offer in  compliance  with  Section  4.3(a)(B),
     including  having  made the  payments  called  for by  Sections  8.3(a) and
     8.3(b).

          8.2 Effect of  Termination.  In the event of the  termination  of this
Agreement  as provided in Section  8.1,  this  Agreement  shall be of no further
force or effect;  provided,  however, that (a) this Section 8.2, Section 8.3 and
Section 9 (and the  Confidentiality  Agreement) shall survive the termination of
this Agreement and shall remain in full force and effect,  and (b) except as set
forth in Section 8.3(d), the termination of this Agreement shall not relieve any
party from any  liability  for any  breach of any  representation,  warranty  or
covenant contained in this Agreement.

          8.3 Expenses; Termination Fees.

               (a)  Except  as set  forth  in this  Section  8.3,  all  fees and
expenses  incurred  in  connection  with  this  Agreement  and the  transactions
contemplated  by  this  Agreement  shall  be paid by the  party  incurring  such
expenses, whether or not the Merger is consummated;  provided, however, that (i)
Parent and the Company  shall share  equally all fees and  expenses,  other than
attorneys'  fees,  incurred  in  connection  with (A) the filing,  printing  and
mailing  of  the  Form  S-4  Registration  Statement  and  the  Prospectus/Proxy
Statement and any  amendments or  supplements  thereto and (B) the filing by the
parties  hereto of the premerger  notification  and report forms relating to the
Merger  under the HSR Act and the filing of any notice or other  document  under
any applicable  foreign antitrust law or regulation;  and (ii) if this Agreement
is terminated by Parent or the Company  pursuant to Section  8.1(d) or by Parent
pursuant  to  Section  8.1(e)  or if  Section  4.3(a)(B)  or  Section  5.2(c) so
requires, then the Company shall make a nonrefundable cash payment to Parent (in
addition to any fee that may be payable  pursuant to Section  8.3(b) or 8.3(c)),
at the time  specified in the next  sentence or in Section  4.3(a)(B) or Section
5.2(c) as applicable, in an amount equal to the aggregate amount of all fees and
expenses (including all attorneys' fees,  accountants' fees,  financial advisory
fees and filing  fees)  that have been paid or that may become  payable by or on
behalf of Parent in connection with the

                                       45
<PAGE>
preparation and negotiation of this Agreement and the Stock Option Agreement and
otherwise in  connection  with the Merger in an  aggregate  amount not to exceed
$2,000,000. In the case of termination of this Agreement by the Company pursuant
to Section 8.1(d), the nonrefundable payment referred to in clause "(ii)" of the
proviso  to the  first  sentence  of this  Section  8.3(a)  shall be made by the
Company  prior  to such  termination;  and in the  case of  termination  of this
Agreement  by Parent  pursuant to Section  8.1(d) or 8.1(e),  the  nonrefundable
payment  referred to clause "(ii)" of the proviso to the first  sentence of this
Section  8.3(a) shall be made by the Company within two business days after such
termination.

               (b) If this Agreement is terminated by Parent pursuant to Section
8.1(e) or if Section  4.3(a)(B) or Section 5.2(c) so requires,  then the Company
shall pay to Parent,  within two business days after such  termination or at the
time  specified  in  Section  4.3(a)(B)  or  Section  5.2(c)  as  applicable,  a
nonrefundable cash fee in the amount of $30,000,000. Any fee required to be paid
pursuant to this Section 8.3(b) shall be in addition to any payment  required to
be made pursuant to Section 8.3(a).

               (c) If this  Agreement  is  terminated  by Parent or the  Company
pursuant to Section 8.1(d) and at the time of the Company  Stockholders' Meeting
an Acquisition Proposal disclosed, announced, commenced, submitted or made prior
thereto shall remain  outstanding  (each such Acquisition  Proposal a "Competing
Proposal"),  then the Company shall pay to Parent,  at the time specified in the
next sentence,  a nonrefundable  cash fee in the amount of  $10,000,000.  In the
case of termination of this Agreement by the Company pursuant to Section 8.1(d),
the fee referred to in the preceding sentence shall be paid by the Company prior
to such termination,  and in the case of termination of this Agreement by Parent
pursuant to Section 8.1(d),  the fee referred to in the preceding sentence shall
be paid by the Company within two business days after such termination.  Any fee
required to be paid pursuant to this Section  8.3(c) shall be in addition to any
payment  required to be made pursuant to Section  8.3(a).  Immediately  upon the
earlier of entering into a definitive  agreement with respect to or consummation
of, at any time within six months after the termination of this  Agreement,  any
transaction  contemplated  by any Competing  Proposal,  the Company shall pay to
Parent an additional  nonrefundable  cash fee in the amount of $20,000,000.  Any
fee required to be paid pursuant to this Section  8.3(c) shall be in addition to
any payment required to be made pursuant to Section 8.3(a).

               (d) If this  Agreement is terminated  pursuant to Section  8.1(g)
because  of a breach by  Parent of any  representation,  warranty  or  covenant,
Parent  shall  pay  to  the  Company,   within  two  business  days  after  such
termination,  a cash fee in the amount of $30,000,000 as liquidated  damages and
as the sole and  exclusive  remedy to the  Company  as a result of such  breach.
Parent  and  the  Company  agree  that  it  would  be  extremely   difficult  or
impracticable  to determine  the Company's  actual  damages in the event of such
breach and that the cash fee required to be paid pursuant to this Section 8.3(d)
is a reasonable estimate of the Company's damages and not a penalty.

     SECTION 9. MISCELLANEOUS PROVISIONS

          9.1 Amendment.  This Agreement may be amended with the approval of the
respective  boards of directors  of the Company and Parent at any time  (whether
before  or after the  approval  of this  Agreement  by the  stockholders  of the
Company); provided, however, that after

                                       46

shall  operate as a waiver of such power,  right,  privilege  or remedy;  and no
single or partial exercise of any such power,  right,  privilege or remedy shall
preclude any other or further  exercise  thereof or of any other  power,  right,
privilege or remedy.

               (b) No party shall be deemed to have waived any claim arising out
of  this  Agreement,  or any  power,  right,  privilege  or  remedy  under  this
Agreement, unless the waiver of such claim, power, right, privilege or remedy is
expressly  set forth in a written  instrument  duly  executed  and  delivered on
behalf of such party;  and any such waiver shall not be  applicable  or have any
effect except in the specific instance in which it is given.

representations and warranties contained in this Agreement or in any certificate

Delaware; (b) if any such action is commenced in a state court, then, subject to
applicable  law,  no party  shall  object to the  removal of such  action to any

     8.4 Severability.  If any provision of this Voting Agreement or any part of
any  such  provision  is  held  under  any   circumstances   to  be  invalid  or
unenforceable  in any  jurisdiction,  then (a) such  provision  or part  thereof
shall, with respect to such  circumstances and in such  jurisdiction,  be deemed
amended to conform to applicable  laws so as to be valid and  enforceable to the
fullest  possible  extent,  (b)  the  invalidity  or  unenforceability  of  such
provision  or part thereof  under such  circumstances  and in such  jurisdiction
shall not  affect the  validity  or  enforceability  of such  provision  or part
thereof under any other circumstances or in any other jurisdiction,  and (c) the
invalidity  or  unenforceability  of such  provision or part  thereof  shall not
affect the validity or  enforceability of the remainder of such provision or the
validity or enforceability of any other provision of this Voting Agreement. Each
provision of this Voting  Agreement is separable  from every other  provision of
this Voting Agreement,  and each part of each provision of this Voting Agreement
is separable from every other part of such provision.

     8.5  Entire  Agreement.  This  Voting  Agreement,  the  Proxy and any other
documents  delivered by the parties in connection herewith constitute the entire
agreement  between the parties  with  respect to the subject  matter  hereof and
thereof  and  supersede  all prior  agreements  and  understandings  between the
parties with respect thereto. No addition to or modification of any provision of
this Voting  Agreement shall be binding upon either party unless made in writing
and signed by both parties.

     8.6 Assignment;  Binding Effect.  Except as provided  herein,  neither this
Voting  Agreement  nor any of the  interests  or  obligations  hereunder  may be
assigned or delegated by Stockholder  and any attempted or purported  assignment
or delegation of any of such interests or obligations shall be void.  Subject to
the preceding sentence,  this Voting Agreement shall be binding upon Stockholder
and his heirs,  estate,  executors,  personal  representatives,  successors  and
assigns,  and shall  inure to the  benefit  of  Parent  and its  successors  and
assigns. Without

                                        6
<PAGE>
limiting  any of the  restrictions  set forth in Section 2 or  elsewhere in this
Voting Agreement, this Voting Agreement shall be binding upon any Person to whom
any Subject  Securities  are  transferred.  Nothing in this Voting  Agreement is
intended  to confer on any Person  (other  than  Parent and its  successors  and
assigns) any rights or remedies of any nature.

     8.7 Specific  Performance.  The parties agree that irreparable damage would
occur in the event that any of the  provisions  of this Voting  Agreement or the
Proxy was not performed in accordance  with its specific  terms or was otherwise
breached.  Stockholder  agrees  that,  in the event of any breach or  threatened
breach by  Stockholder  of any covenant or  obligation  contained in this Voting
Agreement  or in the Proxy,  Parent  shall be entitled (in addition to any other
remedy that may be  available  to it,  including  monetary  damages) to seek and
obtain (a) a decree or order of specific  performance  to enforce the observance
and  performance  of  such  covenant  or  obligation,   and  (b)  an  injunction
restraining such breach or threatened  breach.  Stockholder  further agrees that
neither Parent nor any other Person shall be required to obtain, furnish or post
any bond or similar instrument in connection with or as a condition to obtaining
any remedy referred to in this Section 8.8, and Stockholder  irrevocably  waives
any right he may have to require  the  obtaining,  furnishing  or posting of any
such bond or similar instrument.

     8.8  Non-Exclusivity.  The rights and  remedies of Parent under this Voting
Agreement  are not  exclusive of or limited by any other rights or remedies that
it may have,  whether at law, in equity, by contract or otherwise,  all of which
shall be cumulative (and not  alternative).  Without  limiting the generality of
the  foregoing,  the rights and remedies of Parent under this Voting  Agreement,
and the obligations and liabilities of Stockholder  under this Voting Agreement,
are  in  addition  to  their  respective  rights,   remedies,   obligations  and
liabilities  under common law  requirements  and under all applicable  statutes,
rules and  regulations.  Nothing in this  Voting  Agreement  shall  limit any of
Stockholder's  obligations,  or the  rights or  remedies  of  Parent,  under any
Affiliate  Agreement  between  Parent and  Stockholder;  and nothing in any such
Affiliate Agreement shall limit any of Stockholder's obligations,  or any of the
rights or remedies of Parent, under this Voting Agreement.

     8.9 Governing Law; Venue.

          (a)  This  Voting  Agreement  and the  Proxy  shall  be  construed  in
accordance  with,  and  governed  in all  respects  by, the laws of the State of
Delaware (without giving effect to principles of conflicts of laws).

          (b) Any legal action or other legal proceeding relating to this Voting
Agreement  or the  Proxy or the  enforcement  of any  provision  of this  Voting
Agreement  or the Proxy may be brought or  otherwise  commenced  in any state or
federal court located in the County of San Francisco, California. Stockholder:

               (i)  expressly  and  irrevocably  consents  and  submits  to  the
jurisdiction  of each  state and  federal  court  located  in the  County of San
Francisco,  California  (and  each  appellate  court  located  in the  State  of
California), in connection with any such legal proceeding;

                                        7
<PAGE>
               (ii)  agrees  that  service of any  process,  summons,  notice or
document by U.S.  mail  addressed to him at the address set forth in Section 8.4
shall constitute effective service of such process,  summons, notice or document
for purposes of any such legal proceeding;

               (iii)  agrees  that each state and federal  court  located in the
County of San Francisco,  California,  shall be deemed to be a convenient forum;
and

               (iv)  agrees  not to assert  (by way of  motion,  as a defense or
otherwise), in any such legal proceeding commenced in any state or federal court
located in the County of San Francisco,  California,  any claim that Stockholder
is not subject  personally to the  jurisdiction  of such court,  that such legal
proceeding  has been brought in an  inconvenient  forum,  that the venue of such
proceeding  is improper or that this Voting  Agreement or the subject  matter of
this Voting Agreement may not be enforced in or by such court.

Nothing  contained  in this  Section  8.9 shall be deemed to limit or  otherwise
affect the right of Parent to commence any legal proceeding or otherwise proceed
against Stockholder in any other forum or jurisdiction.

          (c)  STOCKHOLDER  IRREVOCABLY  WAIVES  THE  RIGHT  TO A JURY  TRIAL IN
CONNECTION WITH ANY LEGAL  PROCEEDING  RELATING TO THIS VOTING  AGREEMENT OR THE
PROXY OR THE ENFORCEMENT OF ANY PROVISION OF THIS VOTING AGREEMENT OR THE PROXY.

     8.10 Counterparts.  This Voting Agreement may be executed by the parties in
separate counterparts,  each of which when so executed and delivered shall be an
original,  but all such counterparts shall together  constitute one and the same
instrument.

     8.11  Captions.  The captions  contained in this Voting  Agreement  are for
convenience of reference  only,  shall not be deemed to be a part of this Voting
Agreement and shall not be referred to in connection  with the  construction  or
interpretation of this Voting Agreement.

     8.12  Attorneys'  Fees.  If any  legal  action  or other  legal  proceeding
relating to this Voting  Agreement or the  enforcement  of any provision of this
Voting Agreement is brought against  Stockholder,  the prevailing party shall be
entitled to recover  reasonable  attorneys'  fees, costs and  disbursements  (in
addition to any other relief to which the prevailing party may be entitled).

     8.13 Waiver;  Termination. No failure on the part of Parent to exercise any
power, right,  privilege or remedy under this Voting Agreement,  and no delay on
the part of Parent in  exercising  any power,  right,  privilege or remedy under
this Voting Agreement, shall operate as a waiver of such power, right, privilege
or remedy; and no single or partial exercise of any such power, right, privilege
or remedy shall preclude any other or further  exercise  thereof or of any other
power, right, privilege or remedy. Parent shall not be deemed to have waived any
claim  available to Parent arising out of this Voting  Agreement,  or any power,
right,  privilege  or remedy of Parent under this Voting  Agreement,  unless the
waiver of such claim, power, right, privilege

                                        8
<PAGE>
or remedy is  expressly  set forth in a written  instrument  duly  executed  and
delivered on behalf of Parent;  and any such waiver shall not be  applicable  or
have any effect  except in the  specific  instance in which it is given.  If the
Reorganization  Agreement is terminated,  this Voting  Agreement shall thereupon
terminate.

gender shall  include the masculine  and neuter  genders;  and the neuter gender

in the construction or interpretation of this Voting Agreement.

          (c) As  used  in  this  Voting  Agreement,  the  words  "include"  and
"including,"  and  variations  thereof,  shall  not be  deemed  to be  terms  of
limitation,  but rather  shall be deemed to be  followed  by the words  "without
limitation."

          (d) Except as  otherwise  indicated,  all  references  in this  Voting
Agreement to "Sections" and "Exhibits" are intended to refer to Sections of this
Voting Agreement and Exhibits to this Voting Agreement.

                            FORM OF IRREVOCABLE PROXY

     The undersigned stockholder of INTERLEAF, INC., a Massachusetts corporation
(the  "Company"),  hereby  irrevocably (to the fullest extent  permitted by law)
appoints and constitutes  Randall Bolten,  Scott Neely and BROADVISION,  INC., a
Delaware corporation ("Parent"),  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 outstanding shares of
capital stock of the Company 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 the  Company  which  the
undersigned may acquire on or after the date hereof.  (The shares of the capital
stock of the Company  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 the undersigned agrees that 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 the  Voting  Agreement,  dated as of the date  hereof,  between
Parent  and  the  undersigned  (the  "Voting  Agreement"),  and  is  granted  in
consideration  of Parent  entering  into the  Agreement  and Plan of Merger  and
Reorganization,  dated as of the date hereof, among Parent, Infiniti Acquisition
Sub, Inc. and the Company (the "Reorganization 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  Reorganization  Agreement or the effective time of the
merger contemplated thereby (the "Merger") at any meeting of the stockholders of
the Company,  however called,  or in connection with any solicitation of written
consents from stockholders of the Company, in favor of the approval and adoption
of the Reorganization  Agreement and the approval of the Merger, and in favor of
each of the other actions contemplated by the Reorganization Agreement.

     The undersigned may vote the Shares on all other matters.

     This proxy shall be binding  upon the heirs,  estate,  executors,  personal
representatives,  successors  and  assigns  of the  undersigned  (including  any
transferee of any of the Shares).

     If any  provision  of this proxy or any part of any such  provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such  jurisdiction,  be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible  extent,  (b) the invalidity or
unenforceability  of such provision or part thereof under such circumstances and
in such  jurisdiction  shall not affect the validity or  enforceability  of such
provision  or  part  thereof  under  any  other  circumstances  or in any  other
jurisdiction,  and (c) the invalidity or  unenforceability  of such provision or
part thereof shall not affect the validity or enforceability of the remainder of
such provision or the validity or  enforceability of any other provision of this

                                       11
<PAGE>
proxy.  Each provision of this proxy is separable from every other  provision of
this proxy,  and each part of each  provision  of this proxy is  separable  from
every other part of such provision.

     This proxy shall terminate upon the earlier of the valid termination of the

                             STOCK OPTION AGREEMENT

     THIS STOCK  OPTION  AGREEMENT  ("Option  Agreement")  is entered into as of
January 26, 2000, by and between  INTERLEAF,  INC., a Massachusetts  corporation
(the "Company"), and BROADVISION, INC., a Delaware corporation (the "Grantee").

                                    RECITALS

     A. The Grantee, Infiniti Acquisition Sub, Inc., a Massachusetts corporation
and a wholly owned subsidiary of the Grantee ("Merger Sub"), and the Company are
entering  into an Agreement and Plan of Merger and  Reorganization  of even date
herewith (as amended from time to time, the  "Reorganization  Agreement")  which
provides  (subject to the conditions set forth therein) for the merger of Merger
Sub into the Company (the "Merger").

     B. In  order to  induce  the  Grantee  to  enter  into  the  Reorganization
Agreement, the Company has agreed to enter into this Option Agreement.

                                    AGREEMENT

     The parties to this Option Agreement,  intending to be legally bound, agree
as follows:

     1.  Certain  Definitions.  Capitalized  terms used but not  defined in this
Option  Agreement  shall  have  the  meanings  assigned  to  such  terms  in the
Reorganization Agreement.

     2. Grant of Option. The Company hereby grants to the Grantee an irrevocable
option (the "Option") to purchase,  out of the  authorized but unissued  Company
Common Stock, a number of shares of Company Common Stock equal to up to 19.9% of
the number of shares of Company  Common Stock  outstanding as of the date hereof
(the shares of Company  Common  Stock  purchasable  pursuant  to the Option,  as
adjusted as set forth herein,  being referred to as the "Option  Shares"),  at a
price per Option Share equal to the Exercise Price.  For purposes of this Option
Agreement,  the applicable  "Exercise Price" shall be equal to the lesser of (a)
$52.69,  or (b) the  Exchange  Ratio,  multiplied  by the average of the closing
sales price of a share of Parent Common Stock as reported on the Nasdaq National
Market for the 20  consecutive  trading  days  ending on the second  trading day
preceding the Notice Date (as defined in Section 4(c)).

     3. Term. The Option shall  terminate on the earliest of the following dates
(the "Termination  Date"):  (a) the date on which the Merger becomes  effective;
(b) the date on which the  Reorganization  Agreement is  terminated  pursuant to
Section 8.1 thereof, if an Exercise Event (as defined in Section 4(b)) shall not
have  occurred  on or prior to such date;  or (c) the date six months  after the
date on which the  Grantee  receives  written  notice  from the  Company  of the
occurrence of an Exercise  Event (the "Exercise  Event Notice Date");  provided,
however,  that if an Exercise Event occurs,  and if, by reason of any applicable
Legal Requirement, order, judgment, decree or other legal impediment, the Option
cannot be exercised on the six month  anniversary  of the Exercise  Event Notice
Date, then the  Termination  Date shall be extended until the date 30 days after
the date on which such impediment is removed. The rights of the Grantee

                                        1
<PAGE>
and the  obligations  of the  Company set forth in Sections 7, 8, 9 and 10 shall
not terminate on the Termination  Date, but shall survive beyond the Termination
Date as provided in those Sections.

     4. Exercise of Option.

          (a) The Grantee may exercise the Option,  in whole or in part,  at any
time and from time to time on or  before  the  Termination  Date  following  the
occurrence  of an  Exercise  Event.  If the  Grantee  exercises  the Option with
respect  to  any  Option   Shares   prior  to  the   Termination   Date,   then,
notwithstanding anything to the contrary contained in this Option Agreement, the
Grantee shall be entitled to purchase such Option Shares in accordance  with the
terms of this Option Agreement after the Termination Date.

          (b) For purposes of this Option  Agreement,  an "Exercise Event" shall
be deemed to have occurred if:

               (i) either the  Grantee  or the  Company  shall have the right to
terminate the Reorganization Agreement pursuant to Section 8.1(d) thereof and at
the  time  of  the  Company's  Stockholders'  Meeting  an  Acquisition  Proposal
disclosed,  announced,  commenced,  submitted or made prior thereto shall remain
outstanding; or

               (ii)  the  Grantee   shall  have  the  right  to  terminate   the
Reorganization Agreement pursuant to Section 8.1(e) thereof.

          (c) To exercise  the Option  with  respect to any Option  Shares,  the
Grantee  shall deliver to the Company a written  notice (an  "Exercise  Notice")
specifying:  (i) the number of Option Shares the Grantee will purchase; (ii) the
place at which such  Option  Shares are to be  purchased;  and (iii) the date on
which such  Option  Shares are to be  purchased,  which shall not be sooner than
three  business  days nor later than 20 business days after the date of delivery
of such Exercise  Notice to the Company.  (The date of delivery of such Exercise
Notice to the Company is referred to as the  applicable  "Notice  Date," and the
Option shall be deemed to have been  validly  exercised on such Notice Date with
respect to the Option Shares  referred to in such Exercise  Notice.) The closing
of the  purchase of such Option  Shares (the  applicable  "Closing")  shall take
place at the place  specified in such Exercise  Notice and on the date specified
in such Exercise  Notice (the applicable  "Closing  Date");  provided,  however,
that: (A) if such purchase  cannot be consummated on such Closing Date by reason
of any applicable  Legal  Requirement,  order,  judgment,  decree or other legal
impediment, then the Grantee may extend the Closing Date to a date not more than
20 business days after the date on which such impediment is removed;  and (B) if
prior  notification to or approval of any Governmental  Body is required,  or if
any  waiting  period  must  expire or be  terminated,  in  connection  with such
purchase,  then (1) the Company  shall  promptly  cause to be filed any required
notice or  application  required  to be filed by the  Company  and shall use all
reasonable  efforts to cause  such  notice or  application  to be  processed  as
expeditiously  as possible,  (2) the Company shall cooperate with the Grantee in
the filing of any such notice or application required to be filed by the Grantee
and in the  obtaining  of any  such  approval  required  to be  obtained  by the
Grantee, and (3) the Grantee may extend the Closing Date to a date not more than
20 business  days after the latest date on which any required  notification  has
been made,  any  required  approval has been  obtained or any  required  waiting
period has expired or been terminated.

                                        2
<PAGE>
          (d) If the Grantee  receives net proceeds in connection  with any sale
or  other  disposition  of the  Option  or  Option  Shares  (including,  without
limitation,  any amounts received by the Grantee pursuant to Sections 7, 8 or 9)
which, together with any proceeds received by the Grantee in connection with any
prior such sale or disposition,  any dividends or distributions  received by the
Grantee on any Option  Shares and any amount  paid to the  Grantee  pursuant  to
Sections  8.3(b) and 8.3(c) of the  Reorganization  Agreement  prior  thereto or
thereafter,  are in excess of the Threshold Amount (as defined herein), then all
net proceeds to the Grantee in excess of the Threshold  Amount shall be remitted
to the Company promptly  following receipt thereof.  As used herein,  "Threshold
Amount"  shall mean the amount equal to the greater of (i)  $35,000,000  or (ii)
the product of (A)  200,000 and (B) the average of the closing  sales price of a
share of Parent Common Stock as reported on the Nasdaq  National  Market for the
five  consecutive  trading days ending on the first  trading day  preceding  the
first occurrence of an Exercise Event.

     5. Payment and Delivery of Certificate.

          (a) On each Closing Date, the Grantee shall pay to the Company by wire
in immediately  available funds an amount equal to the applicable Exercise Price
multiplied  by the number of Option  Shares to be  purchased by the Grantee from
the Company on such Closing Date.

          (b) At each Closing, simultaneously with the delivery of the available
funds  referred to in Section  5(a),  the Company shall deliver to the Grantee a
certificate  representing the Option Shares being purchased at such Closing. The
Company represents,  warrants and covenants that such Option Shares will be duly
authorized,  validly issued, fully paid, nonassessable and free and clear of all
Encumbrances, except as may be specifically provided in this Option Agreement.

          (c) The certificate  representing  the Option Shares delivered at each
Closing  shall  be  endorsed   with  a   restrictive   legend  that  shall  read
substantially as follows:

          THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY NOT BE SOLD OR
          OTHERWISE  TRANSFERRED  UNLESS  REGISTERED UNDER SAID ACT OR UNLESS AN
          EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SAID ACT IS AVAILABLE.

If at any time the Grantee  delivers to the Company  evidence  (in the form of a
copy of a letter  from the staff of the SEC or an opinion of counsel  reasonably
satisfactory to the Company,  or in some other form) that the legend referred to
above is not required for purposes of the Securities Act, then the Company shall
promptly  replace such certificate with a certificate that does not include such
legend.

     6. Adjustment Upon Changes in Capitalization, Etc.

          (a) If the outstanding shares of Company Common Stock are changed into
a  different  number  or class of shares  or  securities  by reason of any stock
split, division or

                                        3
<PAGE>
subdivision of shares,  stock dividend,  reverse stock split,  reclassification,
recapitalization  or other  similar  transaction,  then the  number  or class of
shares or other securities subject to the Option, the applicable Exercise Price,
the  Designated  Price (as  defined in Section  7(c)) and the other  numbers and
dollar  amounts   referred  to  in  this  Option  Agreement  shall  be  adjusted
appropriately, and the Company shall ensure that proper provision is made in the
agreements and other  documents  governing such  transaction so that the Grantee
shall  receive  upon  exercise  of the  Option  the  same  number  and  class of
outstanding  shares or other  securities that the Grantee would have received in
respect of the Company Common Stock if the Option had been exercised immediately
prior to such  transaction  or  event or the  record  date for  determining  the
stockholders   entitled  to  participate  in  such   transaction  or  event,  as
applicable.

          (b) If any additional  shares of Company Common Stock are issued after
the date of this Option Agreement (other than pursuant to a transaction or event
described in Section  6(a)),  then the number of shares of Company  Common Stock
then  remaining  subject to the Option shall be increased to the number by which
(i) 19.9% of the number of shares of the Company Common Stock  outstanding after
the issuance of such additional shares exceeds (ii) the sum of (A) the number of
Option Shares  purchasable under the Option immediately prior to the issuance of
such  additional  shares and (B) the number of shares of  Company  Common  Stock
issued upon the exercise of the Option prior to the issuance of such  additional
shares.

          (c) If the Company shall enter into an agreement  (i) to  consolidate,
exchange  shares or merge with any Person,  other than the Grantee or one of the
Grantee's  Subsidiaries,  or (ii) to sell,  lease or  otherwise  transfer all or
substantially all of its assets to any Person,  other than the Grantee or one of
the Grantee's Subsidiaries,  then the Company shall ensure that proper provision
is made in the agreements and other documents governing such transaction so that
the Option shall, upon the consummation of such transaction,  become exercisable
for the stock, securities,  cash or other property that would have been received
by the Grantee if the Grantee had exercised the Option immediately prior to such
transaction  or the record date for  determining  the  stockholders  entitled to
participate in such transaction, as appropriate.

          (d) The  provisions  of  Sections  7, 8, 9 and 10  shall  apply  (with
appropriate  adjustments)  to  any  securities  for  which  the  Option  becomes
exercisable pursuant to this Section 6.

     7. Repurchase at the Request of the Grantee.

          (a) If, at any time during the period  commencing  upon the occurrence
of the first Exercise Event and ending on the date six months after the Exercise
Event Notice Date, the Grantee delivers to the Company a notice stating that the
Grantee is  exercising  its rights under this Section 7, then the Company  shall
repurchase  from the  Grantee (i) that  portion of the Option that then  remains
unexercised,  (ii) all of the shares of Company Common Stock  beneficially owned
by the Grantee that were  previously  purchased by the Grantee upon  exercise of
the Option,  and (iii) the  Grantee's  right to receive  all Option  Shares with
respect to which the Option was previously exercised but which have not yet been
issued and  delivered  to the Grantee.  (The date on which the Grantee  delivers
such notice to the Company is referred to as the "Grantee  Request  Date.") Such
repurchase   shall  be  at  an   aggregate   price  (the   "Grantee   Repurchase
Consideration") equal to the sum of:

                                        4
<PAGE>
               (i) the  aggregate  number of Option Shares with respect to which
the Option has been exercised on or prior to the Grantee  Request Date and which
are beneficially owned by the Grantee, multiplied by the Designated Price;

               (ii) the aggregate  number of Option Shares with respect to which
the Option has been  exercised  on or prior to the  Request  Date but which have
not, as of the Grantee  Request  Date been issued and  delivered to the Grantee,
multiplied by the Designated Price; and

               (iii) the  number  of Option  Shares  with  respect  to which the
Option has not been exercised on or prior to the Grantee Request Date multiplied
by the amount (if any) by which the  Designated  Price  exceeds  the  applicable
Exercise Price.

          (b) If the Grantee exercises its rights under this Section 7, then the
Company shall,  within three  business days after the Grantee  Request Date, pay
the Grantee  Repurchase  Consideration  to the Grantee in immediately  available
funds, and the Grantee shall thereupon  surrender to the Company the certificate
or certificates evidencing the shares of Company Common Stock repurchased by the
Company pursuant to this Section 7.

          (c) For  purposes of this Option  Agreement,  the  "Designated  Price"
means the  highest of (i) the  highest  purchase  price per share paid after the
date of this Option  Agreement  and on or prior to the  applicable  Request Date
pursuant  to any tender or  exchange  offer  made for  shares of Company  Common
Stock,  (ii) the  highest  price per share  paid or to be paid by any Person for
shares of Company Common Stock pursuant to any agreement  contemplating a merger
or other business combination transaction involving the Company that was entered
into after the date of this Option  Agreement and on or prior to the  applicable
Request Date,  (iii) the highest bid price per share of Company  Common Stock as
quoted on the Nasdaq  National  Market (or if Company Common Stock is not quoted
on the Nasdaq National Market, the highest bid price per share of Company Common
Stock as quoted on any other market comprising a part of the Nasdaq Stock Market
or, if the  shares  of  Company  Common  Stock are not  quoted  thereon,  on the
principal  trading market (as defined in Regulation M under the Exchange Act) on
which such  shares are traded as  reported by a  recognized  source)  during the
90-day  period  ending  on the  applicable  Request  Date,  or (iv) the  highest
Exercise  Price paid or payable  for any Option  Shares.  If any  portion of the
consideration  paid or to be paid  pursuant  to  clause  "(i)" or  "(ii)" of the
preceding  sentence is in a form other than cash, then the value of the non-cash
portion  of  such  consideration  shall  be  determined  in  good  faith  by  an
independent  investment banking firm mutually  acceptable to the Company and the
Grantee,  and such  firm's  determination  of such  value  shall  be  final  and
conclusive for all purposes under this Option Agreement.

          (d) The Company hereby undertakes to use reasonable  efforts to obtain
all required  regulatory and legal approvals and to file any required notices as
promptly as practicable in order to accomplish  any repurchase  contemplated  by
this Section 7. Nonetheless,  to the extent that the Company is prohibited under
any applicable  Legal  Requirement  from  repurchasing  the Option or the Option
Shares in full,  the  Company  shall  immediately  so  notify  the  Grantee  and
thereafter  deliver or cause to be delivered,  from time to time, to the Grantee
the  portion of the  Grantee  Repurchase  Consideration  that is  required to be
delivered  pursuant hereto and that it is no longer  prohibited from delivering,
within  three  business  days after the date  which the  Company is no longer so
prohibited, provided, however, that if the Company at any time after delivery to
it of a notice of repurchase  pursuant to Section 7(a) is  prohibited  under any

                                        5
<PAGE>
applicable  Legal  Requirement  from  delivering  to  the  Grantee  the  Grantee
Repurchase Consideration, the Grantee may revoke its notice of repurchase either
in whole or in part  whereupon,  in the case of revocation in part,  the Company
shall promptly (i) deliver to the Grantee that portion of the Grantee Repurchase
Consideration  that the Company is not prohibited from  delivering  after taking
into  account any such  revocation  and (ii)  deliver,  as  appropriate,  to the
Grantee,  either  (A) a new  agreement  evidencing  the right of the  Grantee to
purchase  that number of shares of Company  Common  Stock equal to the number of
shares of Company Common Stock purchasable  immediately prior to the delivery of
the  notice of  repurchase  less the number of shares of  Company  Common  Stock
covered by the portion of the Option  repurchased  and/or (B) a certificate  for
the number of Option Shares covered by the revocation.

          (e) In connection with any repurchase by the Company of any portion of
the Option or shares of Company  Common  Stock  pursuant to this  Section 7, the
Grantee  will be required  to  represent  and  warrant to the  Company  that the
Grantee  has good and valid  title to such  portion  of the  Option or shares of
Company Common Stock, free and clear of all adverse claims, immediately prior to
the consummation of such repurchase.

     8. Repurchase at the Request of the Company.

          (a) If the Grantee has acquired Option Shares pursuant to the exercise
of the Option, then, at any time during the period beginning six months from the
Exercise  Event Notice Date and ending 12 months from the Exercise  Event Notice
Date (the "Purchase Period"), the Company may require the Grantee, upon delivery
to the Grantee of a notice  stating  that the Company is  exercising  its rights
under this  Section 8, to sell to the Company all, but not less than all, of the
Option Shares held by the Grantee.  (The date on which the Company delivers such
notice to the  Grantee is  referred  to as the  "Company  Request  Date.")  Such
repurchase   shall  be  at  an   aggregate   price  (the   "Company   Repurchase
Consideration")  equal to the sum of the aggregate  number of Option Shares held
by the Grantee multiplied by the Designated Price.

          (b) The closing of any  repurchase of Option  Shares  pursuant to this
Section 8 shall take place on the date  designated  by the Company in the notice
delivered  pursuant to Section 8(a),  which date shall be no more than 20 and no
less than three  business  days from the Company  Request  Date.  On the closing
date, the Company shall pay the Company Repurchase  Consideration to the Grantee
in immediately available funds, and the Grantee shall thereupon surrender to the
Company the certificate or certificates  evidencing the shares of Company Common
Stock repurchased by the Company pursuant to this Section 8.

     9. First Refusal.

          (a) If the Grantee  desires to sell,  assign,  transfer  or  otherwise
dispose of all or any of the shares of Company Common Stock or other  securities
acquired by it pursuant to the exercise of the Option,  it will give the Company
written notice of the proposed transaction (the "Offeror's Notice"), identifying
the  proposed  transferee,  the  proposed  purchase  price and the terms of such
proposed transaction. For 10 business days following receipt of such notice, the
Company  shall have the option to elect by written  notice to purchase  all, but
not less than all, of the shares  specified in Offeror's Notice at the price and
upon the terms set forth in such notice.

          (b) The closing of any repurchase of shares of Option Shares  pursuant
to this  Section 9 shall take place  within 10  business  days of the  Company's
election to purchase such

                                        6
<PAGE>
shares.  On the closing date,  the Company  shall pay the purchase  price to the
Grantee  in  immediately  available  funds,  and  the  Grantee  shall  thereupon
surrender to the Company the certificate or  certificates  evidencing the shares
of Company Common Stock repurchased by the Company pursuant to this Section 9.

          (c) If the Company  does not elect to  purchase  the shares of Company
Common Stock or other securities designated in the Offeror's Notice, the Grantee
may,  within 60 days from the date of the  Offeror's  Notice sell such shares of
Company Common Stock or other  securities to the proposed  transferee at no less
than the price specified and on terms not more favorable than those set forth in
the Offeror's  Notice,  provided,  however,  that the provisions of this Section
9(c) will not limit the rights the Grantee may otherwise have if the Company has
elected to purchase such shares of Company Common Stock or other  securities and
wrongfully refuses to complete such purchase.

          (d) The requirements of this Section 9 will not apply to (i) any sale,
assignment,  transfer or  disposition  to an affiliate of the Grantee;  provided
that such  affiliate  agrees  to be bound by the terms  hereof or (ii) any sale,
assignment, transfer or disposition as a result of which the proposed transferee
would own beneficially  not more than 2% of the outstanding  voting power of the
Company.

     10. Registration Rights.

          (a) The Company  shall,  if  requested  by the Grantee at any time and
from time to time within two years  after the first  exercise of the Option (the
"Registration Period"), as expeditiously as practicable, prepare, file and cause
to be declared effective up to two registration  statements under the Securities
Act (including,  at the sole discretion of the Company,  a "shelf"  registration
statement  under Rule 415 under the Securities Act or any successor  provision),
if  registration  under  the  Securities  Act is (in the  Grantee's  good  faith
judgment)  necessary  or  desirable  in order to permit the  offering,  sale and
delivery,  in accordance with the intended  method of sale or other  disposition
stated by the  Grantee,  of any or all shares of Company  Common  Stock or other
securities  that have been acquired or are issuable upon exercise of the Option.
No other securities may be included in any such registration statement,  without
the  Grantee's  prior  written  consent.  The Company  shall use all  reasonable
efforts to cause each such registration statement to become effective, to obtain
all consents or waivers of other parties that are required  therefor and to keep
such  registration  statement  effective for such period as may be as reasonably
necessary to effect such sale or other  disposition.  In  addition,  the Company
shall use all  reasonable  efforts to register  such shares or other  securities
under any  applicable  state  securities  laws.  The  obligations of the Company
hereunder to file a registration statement and to maintain its effectiveness may
be  suspended  for one or more  periods  of time  not  exceeding  90 days in the
aggregate if the Board of Directors of the Company shall have determined in good
faith that the filing of such  registration  statement or the maintenance of its
effectiveness  would require  disclosure of material  nonpublic  information and
that the disclosure  thereof would  materially and adversely affect the Company.
For  purposes  of  determining  whether two  requests  have been made under this
Section 10, only requests  relating to a registration  statement that has become
effective  under the  Securities  Act and that  remained  effective for a period
ending on the earlier of 180 days after becoming  effective or until the Grantee
had disposed of all shares covered thereby shall be counted.

                                        7
<PAGE>
          (b) The expenses  associated  with the  preparation  and filing of any
registration  statement pursuant to this Section 10 and any sale covered thereby
(including  any fees  related  to blue sky  qualifications  and  filing  fees in
respect of the National Association of Securities Dealers,  Inc.) shall be borne
and paid by, and shall be for the sole  account  of,  the  Company  (except  for
underwriting  discounts or  commissions or brokers' fees in respect to shares to
be sold by the Grantee and the fees and disbursement of the Grantee's counsel).

          (c) The Grantee shall provide all information  reasonably requested by
the Company for inclusion in any  registration  statement to be filed hereunder.
If during the  Registration  Period the Company shall propose to register  under
the  Securities  Act the offering,  sale and delivery of Company Common Stock by
the  Company  for cash  pursuant  to a firm  commitment  underwriting,  it shall
(without  limiting the Company's other  obligations under this Section 10) allow
the Grantee the right to  participate  in such  registration  provided  that the
Grantee  participates  in the  underwriting;  provided,  however,  that,  if the
managing underwriter of such offering advises the Company in writing that in its
opinion the number of shares of Company Common Stock requested to be included in
such  registration  exceeds  the number that can be sold in such  offering,  the
Company shall,  after fully  including  therein all securities to be sold by the
Company,  include the shares requested to be included therein by the Grantee pro
rata (based on the number of shares  intended to be included  therein)  with the
shares  intended to be included  therein by Persons  other than the Company.  In
connection with any offering, sale and delivery of Company Common Stock pursuant

     13. Miscellaneous.

          (a) Waiver. No failure on the part of any party to exercise any power,
right, privilege or remedy under this Option Agreement, and no delay on the part
of any party in  exercising  any power,  right,  privilege  or remedy under this
Option Agreement,  shall operate as a waiver of such power, right,  privilege or
remedy; and no single or partial exercise of any such power, right, privilege or
remedy  shall  preclude  any other or further  exercise  thereof or of any other
power,  right,  privilege or remedy. No party shall be deemed to have waived any
claim arising out of this Option Agreement,  or any power,  right,  privilege or
remedy  under this Option  Agreement,  unless the waiver of such  claim,  power,
right,  privilege or remedy is expressly set forth in a written  instrument duly
executed and delivered on behalf of such party; and any such waiver shall not be
applicable  or have any effect  except in the  specific  instance in which it is
given.

to be delivered to any party under this Option Agreement shall be in writing and

          (c) Entire  Agreement;  Counterparts.  This Option  Agreement  and the
agreements  referred to herein constitute the entire agreement and supersede all
prior agreements and understandings,  both written and oral, between the parties
with respect to the subject matter hereof and thereof. This Option Agreement may
be executed in two  counterparts,  each of which shall be deemed an original and
all of which shall constitute one and the same instrument.

          (d) Binding Effect; Benefit;  Assignment.  This Option Agreement shall
be binding upon, and shall be enforceable by and inure solely to the benefit of,
the  parties  hereto and their  respective  successors  and  assigns;  provided,
however,  that neither this Option Agreement nor any of the rights,  interest or
obligations  hereunder may be assigned by either party without the prior written
consent  of the  other  party,  and any  attempted  assignment  of  this  Option
Agreement or any of such rights,  interest or  obligations  without such consent
shall be void and of no effect.  Nothing in this  Option  Agreement,  express or
implied,  is intended to or shall confer upon any Person (other than the parties
hereto and any permitted successors and assigns) any right, benefit or remedy of
any nature under or by reason of this Option Agreement.

          (e) Amendment and  Modification.  This Option Agreement may be amended
with the approval of the  respective  boards of directors of the Company and the
Grantee at any time.  This  Option  Agreement  may not be  amended  except by an
instrument in writing signed on behalf of each of the parties hereto.

          (f) Further  Actions.  The Company agrees to cooperate  fully with the
Grantee  and to  execute  and  deliver  such  further  documents,  certificates,
agreements and  instruments  and to take such other actions as may be reasonably
requested by the Grantee to evidence or reflect the transactions contemplated by
this Option  Agreement  and to carry out the intent and  purposes of this Option
Agreement.

          (g)  Headings.  The  bold-faced  headings  contained  in  this  Option
Agreement are for  convenience  of reference  only,  shall not be deemed to be a
part of this Option  Agreement and shall not be referred to in  connection  with
the construction or interpretation of this Option Agreement.

          (h)  Applicable  Law;  Jurisdiction.  This Option  Agreement  shall 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 any action  between  any of the
parties  arising  out of or  relating  to this  Option  Agreement  or any of the
transactions  contemplated  by this  Option  Agreement:  (a) each of the parties
irrevocably and  unconditionally  consents and submits to the  jurisdiction  and
venue of the state and federal courts located in the State of Delaware; (b) each
of the parties  irrevocably  waives the right to trial by jury;  and (c) each of
the parties irrevocably  consents to service of process by first class certified

mail, return receipt  requested,  postage prepaid,  to the address at which such
party is to receive notice in accordance with Section 12(b).

          (i)  Severability.  If any term,  provision,  covenant or  restriction
contained in this Option Agreement is held by a court of competent  jurisdiction
or other authority to be invalid, void,  unenforceable or against its regulatory
policy,  the  remainder of the terms,  provisions,  covenants  and  restrictions
contained  in this Option  Agreement  shall  remain in full force and effect and
shall in no way be affected, impaired or invalidated.

          (j) Specific Performance.  The Company agrees that (i) in the event of
any breach or threatened  breach by the Company of any  covenant,  obligation or
other provision set forth in this Option Agreement,  the Grantee may be entitled
(in addition to any other remedy that may be available to it) to (A) a decree or
order of  specific  performance  or  mandamus  to  enforce  the  observance  and
performance  of  such  covenant,  obligation  or  other  provision,  or  (B)  an
injunction  restraining such breach or threatened  breach,  and (ii) neither the
Grantee  nor any other  Person  shall be  required  to provide any bond or other
security  in  connection  with  any  such  decree,  order  or  injunction  or in
connection with any related action or proceeding.

          (k) Attorneys' Fees. In any action at law or suit in equity to enforce
this  Option  Agreement  or the  rights  of any of the  parties  hereunder,  the
prevailing  party  in such  action  or suit  shall  be  entitled  to  receive  a
reasonable  sum for its  attorneys'  fees and all  other  reasonable  costs  and
expenses incurred in such action or suit.

          (l)  Non-Exclusivity.  The rights and  remedies of the Company and the
Grantee under this Option Agreement are not exclusive of or limited by any other
rights or remedies which either of them may have,  whether at law, in equity, by
contract or otherwise,  all of which shall be cumulative (and not  alternative).
Without limiting the generality of the foregoing, the rights and remedies of the
Company and the Grantee under this Option  Agreement,  and the  obligations  and
liabilities of the Company and the Grantee under this Option  Agreement,  are in
addition to their respective rights, remedies, obligations and liabilities under
all applicable Legal  Requirements and under the Reorganization  Agreement.  The
covenants  and  obligations  of the Company  set forth in this Option  Agreement
shall be construed as independent of any other agreement or arrangement  between
the Company,  on the one hand, and the Grantee,  on the other.  The existence of
any  claim or cause of action  by the  Company  against  the  Grantee  shall not
constitute a defense to the  enforcement of any of such covenants or obligations
against the Company.

          (m) Construction.

               (i)  For  purposes  of  this  Agreement,   whenever  the  context
requires:  the singular  number shall  include the plural,  and vice versa;  the
masculine  gender shall  include the feminine and neuter  genders;  the feminine
gender shall  include the masculine  and neuter  genders;  and the neuter gender
shall include the masculine and feminine genders.

               (ii) The parties  hereto agree that any rule of  construction  to
the effect that  ambiguities are to be resolved against the drafting party shall
not be applied in the construction or interpretation of this Agreement.

limitation,  but rather  shall be deemed to be  followed  by the words  "without
limitation."

               (iv) Unless otherwise specified,  references in this Agreement to
"Sections" are intended to refer to Sections of this Agreement.
