and approve this Agreement and the Merger.

     2.2.  The Merger.  Promptly following the execution of this Agreement and
           ----------
as soon as is practicable after the satisfaction or waiver of the other

Acquiror Common Stock to be reserved for issuance upon exercise of any of the

set forth on Schedule 1 hereto and collectively referred to as the "Options") of
                                                                    -------

Common Stock issued and outstanding immediately prior to the Effective Time
shall be converted, subject to Section 2.4.3 and Section 2.4.4, into the right
to receive .05863746 of a share of Acquiror Common Stock.  All such shares of
Target Common Stock shall no longer be outstanding and shall automatically be

representing any such shares shall thereafter represent the shares of Acquiror
Common Stock into 

                                       5
<PAGE>
 
which such Target Common Stock has been converted. Certificates previously
representing shares of Target Common Stock shall be exchanged for certificates
representing whole shares of Acquiror Common Stock issued in consideration
therefor upon the surrender of such certificates in accordance with Section 2.7
(or in the case of a lost, stolen or destroyed certificate, upon delivery of an
affidavit (and bond, if required) in the manner provided in Section 2.9).

          2.4.2.  Conversion of Target Preferred Stock.  Each share of Target

Preferred Stock issued and outstanding immediately prior to the Effective Time
shall be converted, subject to Section 2.4.3 and Section 2.4.4, into the right
to receive .05863746 of a share of Acquiror Common Stock.  All such shares of

canceled and retired and shall cease to exist, and each certificate previously
representing any such shares shall thereafter represent the shares of Acquiror

provided in Section 2.9).

          2.4.3.  Canceled Shares.  Each share of capital stock of the Target

held in the treasury of the Target shall automatically cease to be outstanding,
be canceled and retired and no payment or conversion into Acquiror Common Stock
will be made with respect thereto.

          2.4.4.  Fractional Shares.  No certificates or scrip representing
                  -----------------                                        
fractional shares of Acquiror shall be issued in connection with the Merger, and
such fractional share interests will be canceled and thereafter will not entitle
the owner thereof to vote or to any rights as a stockholder of Acquiror.

     2.5.  Assumption of Options.
           ---------------------

          2.5.1.  At the Effective Time, each outstanding Option, whether vested
or unvested, shall be assumed by Acquiror and constitute an option to acquire,
on the same terms and conditions as were applicable under such Option prior to
the Effective Time, the number (rounded down to the nearest whole number) of
shares of Acquiror Common Stock as the holder of such Option would have been
entitled to receive pursuant to the Merger had such holder exercised such Option
in full immediately prior to the Effective Time (not taking into account whether
or not such Option was in fact exercisable), at a price per share equal to (x)
the aggregate exercise price for the Target Common Stock purchasable pursuant to
such Option (not taking into account whether or not such Option was in fact
exercisable) divided by (y) the number of shares of Acquiror Common Stock deemed
purchasable pursuant to such assumed Option (rounded to the nearest whole
number).  At and after the Effective Time, Acquiror will honor all obligations
with respect to such Options under the terms of such Options as in effect on the
date hereof.

          2.5.2.  As soon as practicable after the Closing Date, Acquiror shall
deliver to each holder of an outstanding Option an appropriate notice setting
forth such holder's rights pursuant thereto, and such Option shall otherwise
continue in effect on the same terms and conditions as were in effect prior to
the Effective Time.

<PAGE>
 
          2.5.3.  It is the intention of the parties that the Options assumed by
the Acquiror qualify following the Effective Time as incentive stock options as
defined in Section 422 of the Code to the extent the Options qualified as
incentive stock options immediately prior to the Effective Time.

     2.6.  Charter Documents, Directors, Officers.  At and as of the Effective
           --------------------------------------         
Time, (i) the Certificate of Incorporation and the By-laws of the Target shall
be the Certificate of Incorporation and By-laws of the Surviving Corporation
until thereafter amended as provided by the DGCL, (ii) the directors of the Sub
immediately prior to the Effective Time will be the initial directors of the
Surviving Corporation, until their successors are elected and qualified and
(iii) the officers of the Sub immediately prior to the Effective Time will be
the initial officers of the Surviving Corporation, until their successors are
elected and qualified.

     2.7.  Escrow of Acquiror Common Stock.  Notwithstanding the provisions of
           -------------------------------

-
Shares of the Principals (the "Holdback Amount") allocated on a pro rata basis
                               ---------------
between both Principals. On the date eighteen (18) months after the Closing Date
(or the first business day thereafter) (the "Indemnification Termination Date"),
                                             --------------------------------
the escrow agent will distribute all shares of Merger Shares remaining in the
escrow account from the Holdback Amount after the escrow agent's application of
amounts held pursuant to the Escrow Agreement in payment of the Target and
Principals' indemnification obligations to Acquiror and Sub to an account in the
United States designated by the Stockholder Representative (as defined in the
Escrow Agreement) to the escrow agent in writing at least ten (10) business days
prior to the Indemnification Termination Date. The escrow agent may withhold
from the payment any amounts then in dispute relating to indemnification
obligations of the indemnifying shareholders (the "Sellers") arising under this
Agreement and the Escrow Agreement.

     2.8.  Capital Stock of Sub.  At the Effective Time, each share of Common
           --------------------
Stock of Sub issued and outstanding immediately prior to the Effective Time
shall be converted into the right to receive one (1) validly issued, fully paid
and nonassessable share of Common Stock of Surviving Corporation. Each stock
certificate of Sub evidencing ownership of any such shares shall continue to
evidence ownership of such shares of capital stock of the Surviving Corporation.

     2.9.  Delivery of Certificates.  At the Effective Time, Acquiror shall make
           ------------------------
available, and each holder of Target Common Stock or Target Preferred Stock
(together with the Target Common Stock, the "Target Stock") shall be entitled to
                                             ------------
receive upon surrender to Acquiror or its representatives of any certificate or
certificates evidencing such Target Stock (the "Certificates") for cancellation
                                                ------------
together with any reasonable supporting documentation requested by Acquiror,
including a tax identification number, the aggregate number of Merger Shares to
be issued pursuant to Section 2.4 into which such Target Stock shall have been
converted in the Merger, and upon such surrender of each Certificate and
delivery by Acquiror of the aggregate number of Merger Shares in exchange
therefor, such Certificates shall forthwith be canceled. Until so surrendered,
each Certificate shall be deemed for all corporate purposes to evidence only the
right to receive upon such surrender the aggregate number of Merger Shares into
which the Target Stock represented thereby shall have been converted.

            -------------------------------------------
Common Stock issued upon the surrender for exchange of Certificates in
accordance with the terms of this Article 2 shall be deemed to have been issued
(and paid) in full satisfaction of all rights pertaining to the shares of Target
Stock theretofore represented by such Certificates, and there shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Target Stock which were outstanding immediately
prior to the Effective Time. If, after the Effective Time, Certificates are
presented to the Surviving Corporation for any reason, they shall be canceled
and exchanged as provided in this Article 2, except as otherwise provided by
law.

     2.11.  Lost, Stolen or Destroyed Certificates.  In the event that any
            --------------------------------------
Certificate shall have been lost, stolen or destroyed, upon the making of an

stolen or destroyed and, if required by Acquiror, the posting by such Person of
a bond in such reasonable amount as Acquiror may direct as indemnity against any
claim that may be made against it with respect to such Certificate, the Exchange
Agent will issue in exchange for such lost, stolen or destroyed Certificate the
Acquiror Common Stock and any unpaid dividends or distributions with respect to
Acquiror Common Stock, to which they are entitled pursuant hereto.

take any action contrary to such intention.

            --------------

agency in order for the parties to consummate the transactions contemplated by

     4.4.  Brokers' Fees. Neither of the Principals nor the Target has any
           -------------

     4.5.  Investment.
           ----------

          4.5.1.  Each of the Sellers of Target Stock understands that (i) the

available, and (iii) the Seller has no right to require such registration or
qualification.

          4.5.2.  The Merger Shares to be received by the Sellers pursuant to
this Agreement will be acquired for each Seller's own account and not with a
view to, or intention of, distribution thereof in violation of the Securities
Act, any applicable state securities laws or foreign securities laws, and the
Merger Shares will not be disposed of in contravention of the Securities Act or
any applicable state securities laws or foreign securities laws.

          4.5.3.  Each Seller is an accredited investor as such term is defined
in Section 501 of Regulation D of the Securities Act, has substantial knowledge
and experience in financial and business matters, has specific experience making
investment decisions of a similar nature, and is capable, without the use of a

Seller will provide the Acquiror with such information concerning any prior
investment experience, business or professional experience and other information
as the Acquiror may deem necessary to further evaluate the foregoing
representations.

          4.5.4.  Each Seller has carefully reviewed and understands the risks
of, and other considerations relating to, an investment in the Merger Shares.

          4.5.5.  Each Seller is able to bear the economic risk of his
investment in the Merger Shares for an indefinite period of time because the
Merger Shares have not been registered under the Securities Act and, therefore,
cannot be sold unless subsequently registered under the Securities Act or an
exemption from such registration is available and are subject to additional
restrictions, including without limitation, rights of repurchase, rights of
first refusal and restrictions on transfer as provided in this Agreement.

the Ordinary Course of Business which individually or in the aggregate have not
had a Materially Adverse Effect on the Target, and there has not been a Material

each case, could reasonably be expected to have a Material Adverse Effect on the
Target. The Target is not in default with respect to any order, writ, injunction

such failures to comply which, individually and in the aggregate, would not have
a Material Adverse Effect on the Target, and the Target has all necessary
permits, licenses and other authorizations required to conduct its business in
all material respects as conducted. To the Knowledge of the Target and the
Principals, there is no existing rule, regulation or order, whether federal or

which it is now conducting business or in which it proposes to conduct business.

as conducted and, to the Knowledge of the Target and the Principals, as proposed
to be conducted, and no claim is pending or, to the Knowledge of the Target,
threatened to the effect that the operations of the Target infringe upon,
misappropriate, violate or conflict with the asserted rights of any other Person

Knowledge of the Target and the Principals, threatened to the effect that any
such Intellectual Property owned or licensed by the Target, or which the Target
otherwise has the right to use, is invalid or unenforceable by the Target, and,
to the Knowledge of the Target and the Principals, there is no basis for any
such claim (whether or not pending or threatened).  The Target has not granted
or assigned to any other Person any right to license or sell the software,
trademarks, service marks, Internet domain names, trade names, trade dress,
logos or trade secrets of the Target.  Schedule 4.13.1 hereto sets forth (i) all
                                       ---------------

          4.13.2.  Proprietary Information of Third parties.  No third party has
                   ----------------------------------------                     
claimed in writing or has a valid basis to claim that any Person employed by or
affiliated with the Target has (i) violated or is violating any of the terms or
conditions of such Person's employment, non-competition or nondisclosure
agreement with such third party, (ii) disclosed or is disclosing or utilized or
is utilizing any trade secret or proprietary information or documentation of
such third party or (iii) interfered or is interfering in the employment
relationship between such third party and any of its present or former
employees.  No third party has requested in writing information from the Target
which could reasonably be interpreted to suggest that such a claim might be
contemplated.  No Person employed by the Target has employed or proposes to
employ, any trade secret or any information or documentation in violation of the
proprietary rights of any former employer, and, to the Knowledge of the Target
and the Principals, no Person employed by the Target has violated any
confidential relationship which such Person may have had with any third party,
in connection with the development, manufacture or sale of any product or
proposed product or the development or sale of any service or proposed service
of the Target and there is no reason to believe there will be any such
employment or violation.  None of the execution, delivery or performance of this
Agreement, or the carrying on of the business of the Target as officers,
employees or agents by any officer, director or key employee of the Target or
the conduct of the business of the Target will conflict with or result in a
breach of the terms, conditions or provisions of or constitute a default under
any contract, covenant or instrument under which any such Person is obligated.

inquiry or proposal is made, or any information is requested with respect to any
Proposed Acquisition Transaction.

                                  ARTICLE VII.

                             ----------------------

     The parties agree as follows with respect to the period following the
Closing.

     7.1.  General.  In case at any time after the Closing any further
           -------
action is necessary to carry out the purposes of this Agreement, each of the

or documents in any legal proceeding, interrogatory, subpoena, civil
investigative demand, or similar process) to disclose any Confidential
Information of another party, such party will notify the other party promptly of
the request or requirement so that the party whose Confidential Information is
at issue may seek an appropriate protective order or waive compliance with the
provisions of this Section 7.4. If, in the absence of a protective order or the
receipt of a waiver hereunder, any party is, on the advice of counsel, compelled
to disclose any Confidential Information to any tribunal or else stand liable
for contempt, such party may disclose the Confidential Information to the
tribunal; provided, however, that the disclosing party shall use his or its

parties agree that the court making the determination of invalidity or
unenforceability shall have the power to reduce the scope, duration, or area of

portion of the Merger Shares will be imprinted with a legend substantially in

          This stock certificate was originally issued on March 8, 1999, and has
          ----------------------------------------------------------------------
     not been registered under the Securities Act of 1933, as amended.  The
     ----------------------------------------------------------------------
     transfer of this stock certificate is subject to certain restrictions set
     -------------------------------------------------------------------------
     forth in the Agreement and Plan of Merger.  The issuer of this stock
     --------------------------------------------------------------------
     certificate will furnish a copy of these provisions to the holder hereof
     ------------------------------------------------------------------------
     without charge upon written request.
     ----------------------------------- 

          7.8.2.  Transfer Restrictions.  No shareholder of the Target receiving
                  ---------------------                                         
Merger Shares may transfer any Merger Shares except as provided in this Section
7.8.2.

          (a) Each holder desiring to transfer a stock certificate evidencing a
portion of the Merger Shares first must furnish the Acquiror with (i) a written
opinion reasonably satisfactory to the Acquiror in form and substance from
counsel reasonably satisfactory to the Acquiror by reason of experience to the
effect that the holder may transfer the stock certificate as desired without
registration under the Securities Act and (ii) a written undertaking executed by
the

                                      28
<PAGE>
 
desired transferee reasonably satisfactory to the Acquiror in form and substance
agreeing to be bound by the restrictions on transfer contained herein.

          (b) (i) For a period of one year from and after the Closing Date, the
Principals shall not sell or otherwise transfer their portion of the Merger
Shares; (ii) for a period of one year from and after the first year following
the Closing Date, neither Principal shall sell or otherwise transfer more than
one-third of the Merger Shares he received on the Closing Date; (iii) from and
after the second year following the Closing Date, the Principals may sell or
otherwise transfer their Merger Shares in accordance with Section 7.8.2(a);
provided, however, that if the Acquiror breaches the Employment Agreement of a
-----------------                                                             
Principal, such Principal may immediately sell or otherwise transfer his
respective Merger Shares in accordance with Section 7.8.2(a).

          7.8.3.  Right to Repurchase.  In the event that either Principal's
                  -------------------                                       
Employment Agreement is terminated for any reason other than (i) the Principal's
death or disability or (ii) a material breach of the Employment Agreement by the
Acquiror, the Acquiror shall have the right to repurchase such proportion of the
Principal's Merger Shares for a price of $0.10 per share as determined by the
following formula:
                                     24 - n
                                     ------
                                       24

               where n = the number of full months worked by the
                         respective Principal since the Closing Date
    
For the purposes of this caluculation, the Holdback Amount shall be counted as
part of the Principal's Merger Shares.  The Acquiror's right to repurchase under
this Section 7.8.3 shall be a right to repurchase Principal's Merger Shares not
then held in escrow.  In the event there is a sale of all or substantially all
of the Acquiror's assets or any merger, consolidation or stock sale that results
in the holders of the Acquiror's capital stock immediately prior to such
transaction owning less than 50% of the voting power of the Acquiror's capital
stock immediately after such transaction (a "Change of Control"), the Acquiror's
                                             -----------------                  
right to repurchase the shares as set forth above shall only be applicable to
one-half of the Merger Shares which otherwise would have been subject to the
repurchase right under this Section 7.8.3 as of the date of such Change of
Control; provided, however, that in the event the acquiror in such a Change of
         -----------------                                                    
Control transaction does not assume a Principal's Employment Agreement in full
or upon substantially the same or better terms, the Acquiror's right to
repurchase the shares as set forth above shall terminate with respect to all of
the Merger Shares.

          7.8.4.  Right of First Refusal.  For a period of two years commencing
                  ----------------------                                       
upon the Closing Date, if either Principal proposes to sell or otherwise
transfer his Merger Shares at any time from and after the Closing Date, such
Principal shall notify the Acquiror in accordance with Section 12.7 hereof that
it proposes to complete a transfer of some or all, as the case may be, of its
Merger Shares prior to the consummation of such transfer.  The notice shall
specify the number of Merger Shares to be transferred, the price at which such
shares are to be transferred and the other terms and conditions of such proposed
transfer.  The Merger Shares proposed to be transferred as set forth in the
notice shall be subject to an option of the Acquiror ("Right of First Refusal")
                                                       ----------------------  
to purchase such Merger Shares at the same price and on the same terms and
conditions as are set forth in the notice.  The Acquiror must exercise its Right
of First Refusal within a reasonable time period following

                                      29

receipt of the notice of the proposed transfer by notifying the appropriate
Principal in accordance with Section 12.7 hereof.

opinions, instruments, and other documents required to effect the transactions
contemplated hereby will be reasonably satisfactory in form and substance to the
Principals.

     The Principals may waive any condition specified in this Section 8.2 if
they execute a writing so stating at or prior to the Closing.

                                  ARTICLE IX.

                    REMEDIES FOR BREACHES OF THIS AGREEMENT
                    ---------------------------------------

     9.1.  Survival of Representations and Warranties.  All of the 
           ------------------------------------------
representations and warranties of the Principals and the Target contained in
Article 4 above (other than Section 4.6 above) and all of the representations
and warranties of the Acquiror contained in Article 5 and Section 2.12 above
shall survive the Closing hereunder (even if the damaged party knew or had
reason to know of any misrepresentation or breach of warranty at the time of
Closing) and continue in full force and effect for a period of eighteen months
thereafter; provided, however, that the representations and warranties contained
            -----------------
in Section 4.6 above shall survive the Closing hereunder until the expiration of
all relevant statutes of limitation (including any extensions thereof).

     9.2.  Indemnification Provisions for Benefit of the Acquiror.
           ------------------------------------------------------ 

          9.2.1.  In the event either of the Principals or the Target breaches
any of their representations, warranties and covenants contained herein (except
for the representations and warranties contained in Section 4.6), and, if there
is an applicable survival period pursuant to Section 9.1 above, provided that
the Acquiror Indemnified Party (as defined herein) makes a written claim for
indemnification against any of the Principals pursuant to Section 9.4 below
within the applicable time periods, then each of the Sellers shall indemnify
Acquiror and its partners, officers, directors, employees, stockholders and
agents ("Acquiror Indemnified Parties") from and against the entirety of any
         ----------------------------                                       
Adverse Consequences the Acquiror Indemnified Party may suffer through and after
the date of the claim for indemnification (including any Adverse Consequences
the Acquiror Indemnified Party may suffer after the end of any applicable
survival period) resulting from, arising out of, relating to, in the nature of,
or caused by the breach; provided, however, that the Sellers shall not have any
                         -----------------                                     
obligation to indemnify the Acquiror Indemnified Party from and against any
Adverse Consequences resulting from, arising out of, relating to, in the nature
of, or caused by the breach of any representation or warranty of the Principals
or the Target contained in Article 4 above until the Acquiror Indemnified Party
has suffered Adverse Consequences by reason of all such breaches in excess of a
$50,000 aggregate deductible (after which point the Sellers will be obligated
only to indemnify the Acquiror from and against further such Adverse
Consequences); provided further, however, that in no event shall such Sellers be
               ----------------  -------                                        
liable pursuant to this Section 9.2.1 to the Acquiror Indemnified Parties, on
any claim or claims made by the Acquiror Indemnified

                                      32
<PAGE>
 
Parties, for any Adverse Consequences in excess of the aggregate value of the
shares (which value is to be determined in accordance with Section 9.2.4) then
held in escrow pursuant to Section 2.7.

          9.2.2.  In the event the Principals or Sellers breach their
representations and warranties contained in Section 4.6, and, if there is an
applicable survival period pursuant to Section 9.1 above, provided that the
Acquiror Indemnified Party makes a written claim for indemnification against any
of the Principals pursuant to Section 9.4 below, then each of the Principals
shall, jointly and severally, indemnify and hold harmless such Acquiror
Indemnified Party from and against the entirety of any Adverse Consequences the
Acquiror Indemnified Party may suffer through and after the date of the claim
for indemnification (including any Adverse Consequences the Acquiror Indemnified
Party may suffer after the end of any applicable survival period) resulting
from, arising out of, relating to, in the nature of, or caused by the breach;
provided, however, that the Principals shall not have any obligation to
-----------------                                                      
indemnify the Acquiror Indemnified Party from and against any Adverse
Consequences resulting from, arising out of, relating to, in the nature of, or
caused by the breach of any representation or warranty of the Principals
contained in Section 4.6 above until the Acquiror Indemnified Party has suffered
Adverse Consequences by reason of all such breaches in excess of a $50,000
aggregate deductible (after which point the Sellers will be obligated only to
indemnify the Acquiror from and against further such Adverse Consequences).

          9.2.3.  Each of the Principals agrees to indemnify the Acquiror from
and against the entirety of any Adverse Consequences the Acquiror may suffer
resulting from, arising out of, relating to, in the nature of, or caused by any
liability of the Target (i) for any Taxes of the Target with respect to any Tax
year or portion thereof ending on or before the Closing Date (or for any Tax
year beginning before and ending after the Closing Date to the extent allocable
(determined in a manner consistent with Article 10) to the portion of such
period beginning before and ending on the Closing Date), to the extent such
income Taxes are not reflected in the reserve for Tax liability (rather than any
reserve for deferred Taxes established to reflect timing differences between
book and Tax income) shown on the face of the Target's Most Recent Balance Sheet
(rather than in any notes thereto), as such reserve is adjusted for the passage
of time through the Closing Date in accordance with the past custom and practice
of the Target in filing their Tax Returns and (ii) for the unpaid Taxes of any
Person (other than the Target) under Reg.  (S)1.1502-6 (or any similar provision
of state, local, or foreign law), as a transferee or successor, by contract, or
otherwise.

          9.2.4.  The indemnification obligations of the Principals or the
Target hereunder shall be satisfied by either the transfer of Merger Shares or
the payment of cash to the Acquiror Indemnified Party, at the election of the
party owning such obligation.  In the event that the Seller Representatives (as
defined in the Escrow Agreement) elect to satisfy their indemnification
obligations by the transfer of Merger Shares, such shares shall be valued for
this purpose as the value of the closing trade price of the Acquiror's Common
Stock on the date of execution of this Agreement.

     9.3. Indemnification Provisions for Benefit of the Principals. In the event
          --------------------------------------------------------
the Acquiror breaches any of its representations, warranties, and covenants
contained herein, and, if there is an applicable survival period pursuant to
Section 9.1 above, provided that a Principal makes a written claim for
indemnification against the Acquiror pursuant to Section 9.4 below within two
years, then

                                      33
<PAGE>
 
the Acquiror agrees to indemnify each of the Principals from and against the
entirety of any Adverse Consequences the Principal may suffer through and after
the date of the claim for indemnification (including any Adverse Consequences
the Principal may suffer after the end of any applicable survival period)
resulting from, arising out of, relating to, in the nature of, or caused by the
breach provided, however, that the Acquirors shall not have any obligation to
       -----------------
indemnify the Principal from and against any Adverse Consequences resulting
from, arising out of, relating to, in the nature of, or caused by the breach of
any representation or warranty of the Principals or the Target contained in
Article 5 above until the Principal has suffered Adverse Consequences by reason
of all such breaches in excess of a $50,000 aggregate deductible (after which
point the Acquiror will be obligated only to indemnify the Principal from and
against further such Adverse Consequences); provided further, however, that in
                                            -------------------------
no event shall the Acquiror be liable pursuant to this Article 9 to the
Principals, on any claim or claims made by Principals, for any Adverse
Consequences in excess of the aggregate value of the shares (which value is to
be determined in accordance with Section 9.2.4) then held in escrow pursuant to
Section 2.7.

     9.4.  Procedure for Claims between Parties
           ------------------------------------

          9.4.1.  Any Acquiror Indemnified Party or Seller Indemnified Party
seeking indemnification hereunder shall, within the relevant limitation period
provided for in Section 9.1 above, give to the party obligated to provide
indemnification to such Indemnified Party (the "Indemnitor") a notice (a "Claim
                                                ----------                -----
Notice") describing in reasonable detail the facts giving rise to any claims for
------                                                                          
indemnification hereunder and shall include in such Claim Notice (if then known)
the amount or the method of computation of the amount of such claim, and a
reference to the provision of this Agreement or any agreement, document or
instrument executed pursuant hereto or in connection herewith upon which such
claim is based provided that failure to give such notice shall not relieve the
Indemnitor of its obligations hereunder except to the extent it shall have been
prejudiced by such failure.

          9.4.2.  In the event that the indemnitee is an Acquiror Indemnified
Party, all provisions set forth in Article 9 regarding notices to, or consents
of, the Sellers shall be determined by the Seller Representative (as defined in
the Escrow Agreement) and shall be binding upon all Sellers.

     9.5.  Matters Involving Third parties
           -------------------------------

          9.5.1.  If any third party shall notify any party (the "Indemnified
                                                                  -----------
Party") with respect to any matter (a "Third Party Claim") which may give rise
-----                                  -----------------                      
to a claim for indemnification against any other party (the "Indemnifying
                                                             ------------
Party") under this Section 9.1, then the Indemnified Party shall promptly notify
each Indemnifying Party thereof in writing; provided, however, that no delay on
                                            -----------------                  
the part of the Indemnified Party in notifying any Indemnifying Party shall
relieve the Indemnifying Party from any obligation hereunder unless (and then
solely to the extent) the Indemnifying Party thereby is prejudiced.

          9.5.2.  Any Indemnifying Party will have the right to assume the
defense of the Third Party Claim with counsel of his or its choice reasonably
satisfactory to the Indemnified Party at any time within 15 days after the
Indemnified Party has given notice of the Third Party Claim; provided, however,
                                                             ----------------- 
that the Indemnifying Party must conduct the defense of the Third Party Claim
actively and diligently thereafter in order to preserve its rights in this
regard; and provided further
            ----------------                                                  

                                      34
<PAGE>
 
that the Indemnified Party may retain separate co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim.

          9.5.3.  So long as the Indemnifying Party has assumed and is
conducting the defense of the Third Party Claim in accordance with Section 9.4.2
above, (i) the Indemnifying Party will not consent to the entry of any judgment
or enter into any settlement with respect to the Third Party Claim without the
prior written consent of the Indemnified Party (not to be withheld unreasonably)
unless the judgment or proposed settlement involves only the payment of money
damages by one or more of the Indemnifying Parties and does not impose an
injunction or other equitable relief upon the Indemnified Party and (ii) the
Indemnified Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnifying Party (not to be withheld unreasonably).

          9.5.4.  In the event none of the Indemnifying Parties assumes and
conducts the defense of the Third Party Claim in accordance with Section 9.5.2
above, however, (i) the Indemnified Party may defend against, and consent to the
entry of any judgment or enter into any settlement with respect to, the Third
Party Claim in any manner he or it reasonably may deem appropriate (and the
Indemnified Party need not consult with, or obtain any consent from, any
Indemnifying Party in connection therewith) and (ii) the Indemnifying Parties
will remain responsible for any Adverse Consequences the Indemnified Party may
suffer resulting from, arising out of, relating to, in the nature of, or caused
by the Third Party Claim to the fullest extent provided in this Article 9.

     9.6.  Determination of Adverse Consequences. The parties shall make
           -------------------------------------
appropriate adjustments for Tax consequences and insurance coverage and take
into account the time cost of money (using a mutually agreed upon rate as the
discount rate) in determining Adverse Consequences for purposes of this Article
9.

     9.7.  Other Indemnification Provisions.  The parties acknowledge and agree
           --------------------------------
that the foregoing indemnification provisions in this Article 9 shall be the
exclusive remedy of the parties for any breach of the representations and
warranties contained herein. Each of the Principals hereby agrees that he or it
will not make any claim for indemnification against the Target by reason of the
fact that he or it was a director, officer, employee, or agent of any such
entity or was serving at the request of any such entity as a partner, trustee,
director, officer, employee, or agent of another entity (whether such claim is
for judgments, damages, penalties, fines, costs, amounts paid in settlement,
losses, expenses, or otherwise and whether such claim is pursuant to any
statute, charter document, bylaw, agreement, or otherwise) with respect to any
action, suit, proceeding, complaint, claim, or demand brought by a party against
such other party (whether such action, suit, proceeding, complaint, claim, or
demand is pursuant to this Agreement, applicable law, or otherwise).

                                   ARTICLE X.

                                  TAX MATTERS
                                  -----------

     The following provisions shall govern the allocation of responsibility as
between Acquiror and Principals for certain Tax matters following the Closing
Date:

                                      35
<PAGE>
 
     10.1.  Tax Periods Ending on or Before the Closing Date. Acquiror shall
            ------------------------------------------------
prepare or cause to be prepared and file or cause to be filed all Tax Returns
for the Target for all periods ending on or prior to the Closing Date which are
filed after the Closing Date. Acquiror shall permit the Principals to review and
comment on each such Tax Return described in the preceding sentence prior to
filing and shall make such revisions to such Tax Returns as are reasonably
requested by the Principals. The Principals shall reimburse Acquiror for Taxes
of the Target with respect to such periods within 15 days after payment by
Acquiror or the Target of such Taxes to the extent such Taxes are not reflected
in the reserve for Tax liability (rather than any reserve for deferred Taxes
established to reflect timing differences between book and Tax income) shown on
the face of the Closing Balance Sheet.

     10.2.  Tax Periods Beginning Before and Ending After the Closing Date
            --------------------------------------------------------------
Acquiror shall prepare or cause to be prepared and file or cause to be filed any
Tax Returns of the Target for Tax periods which begin before the Closing Date
and end after the Closing Date. The Principals shall pay to Acquiror within 15
days after the date on which Taxes are paid with respect to such periods an
amount equal to the portion of such Taxes which relates to the portion of such
taxable period ending on the Closing Date to the extent such Taxes are not
reflected in the reserve for Tax liability (rather than any reserve for deferred
Taxes established to reflect timing differences between book and Tax income)
shown on the face of the Closing Balance Sheet. For purposes of this Section, in
the case of any Taxes that are imposed on a periodic basis and are payable for a
taxable period that includes (but does not end on) the Closing Date, the portion
of such Tax which relates to the portion of such taxable period ending on the
Closing Date shall (i) in the case of any Taxes other than Taxes based upon or
related to income or receipts, be deemed to be the amount of such Tax for the
entire taxable period multiplied by a fraction the numerator of which is the
number of days in the taxable period ending on the Closing Date and the
denominator of which is the number of days in the entire taxable period, and
(ii) in the case of any Tax based upon or related to income or receipts be
deemed equal to the amount which would be payable if the relevant taxable period
ended on the Closing Date. Any credits relating to a taxable period that begins
before and ends after the Closing Date shall be taken into account as though the
relevant taxable period ended on the Closing Date. All determinations necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of the Target.

     10.3.  Refunds and Tax Benefits.  Any Tax refunds that are received by
            ------------------------
Acquiror or the Target, and any amounts credited against Tax to which Acquiror
or the Target become entitled, that relate to Tax periods or portions thereof
ending on or before the Closing Date shall be for the account of the Principals,
and Acquiror shall pay over to the Principals any such refund or the amount of
any such credit within 15 days after receipt or entitlement thereto. In
addition, to the extent that a claim for refund or a proceeding results in a
payment or credit against Tax by a Taxing authority to the Acquiror or the
Target of any amount accrued on the Closing Balance Sheet, the Acquiror shall
pay such amount to the Principals within 15 days after receipt or entitlement
thereto.

     10.4.  Cooperation on Tax Matters.
            --------------------------

          10.4.1.  The Acquiror, the Target and the Principals shall cooperate
fully, as and to the extent reasonably requested by the other party, in
connection with the filing of Tax Returns pursuant to this Agreement and any
audit, litigation or other proceeding with respect to Taxes.

                                      36
<PAGE>
 
Such cooperation shall include the retention and (upon the other party's
request) the provision of records and information which are reasonably relevant
to any such audit, litigation or other proceeding and making employees available
on a mutually convenient basis to provide additional information and explanation
of any material provided hereunder. The Target and the Principals agree (i) to
retain all books and records with respect to Tax matters pertinent to the Target
relating to any taxable period beginning before the Closing Date until the
expiration of the statute of limitations (and, to the extent notified by the
Acquiror or the Principals, any extensions thereof) of the respective taxable
periods, and to abide by all record retention agreements entered into with any
Taxing authority, and (ii) to give the other party reasonable written notice
prior to transferring, destroying or discarding any such books and records and,
if the other party so requests, the Target or the Principals, as the case may
be, shall allow the other party to take possession of such books and records.

          10.4.2.  The Acquiror and the Principals further agree, upon request,
to use their best efforts to obtain any certificate or other document from any
governmental authority or any other Person as may be necessary to mitigate,
reduce or eliminate any Tax that could be imposed (including, but not limited
to, with respect to the transactions contemplated hereby).

          10.4.3.  The Acquiror and the Principals further agree, upon request,
to provide the other party with all information that either party may be
required to report pursuant to (S)6043 of the Code and all Treasury Department
Regulations promulgated thereunder.

     10.5.  Tax Sharing Agreements.  All Tax sharing agreements or similar 
            ----------------------
agreements with respect to or involving the Target shall be terminated as of the
Closing Date and, after the Closing Date, the Target shall not be bound thereby
or have any liability thereunder.

     10.6.  Certain Taxes.  All transfer, documentary, sales, use, stamp,
            -------------
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement shall be paid by the
Principals when due, and the Principals will, at their own expense, file all
necessary Tax Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration and other Taxes and fees, and, if
required by applicable law, Acquiror will, and will cause its Affiliates to,
join in the execution of any such Tax Returns and other documentation.

                                  ARTICLE XI.

                                  TERMINATION
                                  -----------

     11.1.  Termination of Agreement.  Certain of the parties may terminate
            ------------------------
this Agreement as provided below:

          11.1.1.  the Acquiror and the Principals may terminate this Agreement
by mutual written consent at any time prior to the Closing;

          11.1.2.  the Acquiror may terminate this Agreement by giving written
notice to the Principals at any time prior to the Closing (i) in the event that
either of the Principals has breached any material representation, warranty, or
covenant contained in this Agreement in any material respect, the Acquiror has
notified the Principals of the breach, and the breach has continued without
<PAGE>
 
cure for a period of 30 days after the notice of breach or (ii) if the Closing
shall not have occurred on or before March 16, 1999, by reason of the failure of
any condition precedent under Section 8.1 hereof (unless the failure results
primarily from the Acquiror itself breaching any representation, warranty, or
covenant contained in this Agreement); and

          11.1.3.  the Principals may terminate this Agreement by giving written
notice to the Acquiror at any time prior to the Closing (i) in the event the
Acquiror has breached any material representation, warranty, or covenant
contained in this Agreement in any material respect, any of the Principals has
notified the Acquiror of the breach, and the breach has continued without cure
for a period of 30 days after the notice of breach or (ii) if the Closing shall
not have occurred on or before March 16, l999, by reason of the failure of any
condition precedent under Section 8.2 hereof (unless the failure results
primarily from any of the Principals themselves breaching any representation,
warranty, or covenant contained in this Agreement).

     11.2.  Effect of Termination.  If any party terminates this  Agreement
            ---------------------
pursuant to Section 11.1 above, all rights and obligations of the parties
hereunder shall terminate without any liability of any party to any other party
(except for any liability of any party then in breach); provided, however, that
                                                        -----------------
Sections 7.4, 7.7 and 9.1-9.6, inclusive, shall survive termination.

                                 MISCELLANEOUS
                                 -------------

     12.1.  No Third-party Beneficiaries.  This Agreement shall not confer any

nonetheless shall remain responsible for the performance of all of its
obligations hereunder).

     12.4.  Counterparts.  This Agreement may be executed in one or
            ------------
more counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.
