                         AGREEMENT AND PLAN OF MERGER

          AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated June 19, 2000,
                                              ---------
by and between BLAZE SOFTWARE, INC., a Delaware corporation (the "Company"), and
                                                                  -------
BROKAT AKTIENGESELLSCHAFT, a German corporation which is in the process of
changing its name from BROKAT Infosystems Aktiengesellschaft (the "Parent").
                                                                   ------

                                   RECITALS

          (a) The management board (Vorstand) of the Parent and the board of
directors of the Company have determined that the merger of Merger Sub with and
into the Company on the terms and subject to the conditions set forth on this
Agreement (the "Merger"), with the Company surviving as a wholly owned
                ------
subsidiary of the Parent, is advisable and that it is in the best interests of
their respective corporations and stockholders to combine the respective
businesses of the Parent and the Company, and consequently have approved the
merger of Merger Sub with and into the Company (the "Merger") and have approved
                                                     ------
and adopted the Merger and this Agreement, in accordance with the General
Corporation Law of the State of Delaware (the "DGCL") and the laws of Germany.
                                               ----

          (b) Concurrently with the execution of this Agreement, as a condition
to the willingness of the Parent to enter into this Agreement, (i) certain
holders (the "Principal Stockholders") of the Company's common stock, par value
              ----------------------
$0.0001 per share ("Company Common Stock"), are entering into one or more
                    --------------------
stockholders' agreements, dated as of the date hereof, with the Parent and the
Company, copies of which are attached to this Agreement as Exhibit A (the

"Company Voting Agreements").
--------------------------

          (c) For federal income tax purposes it is intended that the Merger
shall qualify as a reorganization under the provisions of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), and the rules and
                                                ----
regulations promulgated under the Code.

          (d) Certain terms used in this Agreement which are not capitalized
have the meanings specified in Section 8.1.

          NOW, THEREFORE, the parties to this Agreement, intending to be legally
bound by this Agreement, agree as follows:
<PAGE>

                                  ARTICLE II

                                  THE MERGER

    Section 2.1  The Merger.

          (a) As promptly as practicable following the date hereof, the Parent
and the Company shall appoint a United States bank or trust company or other
independent financial institution in the United States (the "Exchange Agent") to
                                                             --------------
act as exchange agent for the Share Exchange (as defined in Section 2.2 (a)(ii)
hereof) and the delivery of the Merger Consideration (as defined in Section
2.1(c) hereof).  Following such appointment, the Exchange Agent (as agent for
the Parent) shall cause to be incorporated pursuant to the DGCL a corporation
which shall be a constituent company in the Merger ("Merger Sub") and which
                                                     ----------
shall not transact any business other than participating in the Merger as
described herein.  To accommodate the transactions described in this Article I
and Article II, the Exchange Agent shall hold all the issued and outstanding
shares of common stock, par value $0.01 per share, of the Merger Sub (the
"Merger Sub Common Stock") as agent for the Parent; at and following the
------------------------
Effective Time, the Exchange Agent shall receive and hold the Merger
Consideration and the Exchange Fund solely as agent for the Company's
shareholders.  The Parent and the Company shall enter into an exchange agent
agreement with the Exchange Agent in form and substance reasonably satisfactory
to the Parent and the Company, which agreement shall set forth the duties,
responsibilities and obligations of the Exchange Agent consistent with the terms
of this Agreement.

          (b) Upon the terms and subject to the conditions set forth in this
Agreement, at the Effective Time, in accordance with the DGCL, Merger Sub shall
be merged with and into the Company in accordance with this Agreement and the
separate corporate existence of Merger Sub shall cease.  The Company shall be
the surviving corporation in the Merger (sometimes referred to as the "Surviving
                                                                       ---------
Corporation") and shall continue to be governed by the laws of the State of
-----------
Delaware, and the separate corporate existence of the Company with all its
rights, privileges, immunities, powers and franchises shall continue unaffected
by the Merger.

    Section 2.2  Effective Time.  As soon as practicable following the
satisfaction or, if permissible, waiver of the conditions set forth in Article
VI but in no event later than the third business day following such satisfaction
or waiver (unless another date is agreed to by each of the parties in writing),
the Company, Merger Sub and the Parent will cause a Certificate of Merger (the
"Certificate of Merger") to be signed, acknowledged and delivered for filing
----------------------
with the Secretary of State of the State of Delaware as provided in Section 251
of the DGCL.  The Merger shall become effective at the time when a Certificate
of Merger has been duly filed with the Secretary of State of the State of
Delaware or such other subsequent date or time as shall be agreed upon

                                       2
<PAGE>

by the parties and set forth in the Certificate of Merger and in accordance with
the DGCL (the "Effective Time").
               --------------

    Section 2.3 Closing. Subject to the satisfaction or waiver of all of the
conditions to closing contained in Article VI hereof, the closing of the
Merger (the "Closing") shall take place (a) at the offices of Paul, Weiss,
             -------
Rifkind, Wharton & Garrison, New York, New York at 12:00 (noon, New York time)
on the third business day after the day on which the last to be fulfilled or
waived of such conditions (other than those conditions that by their nature are
to be satisfied at the Closing, but subject to the fulfillment or waiver of
those conditions) shall be satisfied or waived in accordance with this Agreement
or (b) at such other place and time or on such other date as the Company and the
Parent may agree in writing (the "Closing Date").
                                  ------------

    Section 2.4 Effects of the Merger. The Merger shall have the effects set
forth in the DGCL, including Section 259 of the DGCL, and in accordance
therewith, at the Effective Time, all the properties, rights, privileges, powers
and franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all debts, liabilities and duties of the Company and Merger Sub
shall become the debts, liabilities and duties of the Surviving Corporation.

    Section 2.5 The Certificate of Incorporation. The certificate of
incorporation of Merger Sub in effect immediately prior to the Effective Time
shall, from and after the Effective Time, be the certificate of incorporation of
the Surviving Corporation until duly amended as provided therein or by
applicable law; provided, however, that at the Effective Time, the certificate
of incorporation of the Surviving Corporation shall be amended so that the name
of the Surviving Corporation shall be "Blaze Software, Inc."

    Section 2.6 The By-Laws. The by-laws of Merger Sub in effect immediately
prior to the Effective Time shall, from and after the Effective Time, be the
by-laws of the Surviving Corporation until duly amended as provided therein or

to receive the Merger Consideration and any distribution or dividend under
Section 2.2(c) in each case without interest.

      Section 3.2  Exchange of Certificates.

          (a) The Share Exchange.  Consistent with the terms of this Agreement,
as soon as practicable following the signing of this Agreement and in no event
later than five business days following the Effective Time (unless otherwise
agreed to by each of the parties in writing):

          (b)  the Parent shall issue the Parent Common Stock underlying the
Parent ADSs to be issued on behalf of the Parent in connection with the Merger
and cause American Depositary Receipts ("ADRs") representing Parent ADSs
                                         ----
representing such Parent Common Stock (such Parent ADSs, together with any
dividends or distributions with respect thereto to which the holders of
Certificates may be entitled pursuant to Section 2.2(c) and with the proceeds
held in the Exchange Trust, being hereinafter referred to as the "Exchange
                                                                  --------
Fund") to be delivered to the Exchange Agent, for the benefit of the holders of
Certificates, for exchange in accordance with this Article II, through the
Exchange Agent, issuable pursuant to Section 2.1(c) in exchange for outstanding
shares of Company Common Stock; and

          (c) the Exchange Agent shall contribute, on behalf of the former
stockholders of the Company, all of the issued and outstanding shares of
Surviving Corporation Common Stock to the Parent as a contribution in kind (the
"Share Exchange").
 --------------

          Subject to Section 5.20, the Share Exchange shall be effected in
accordance with Sections 52, 203, 185 et seq. (including in particular Section
187) of the German Stock Corporation Law (Aktiengesetz), in each case to the
extent each such provision may be applicable, by registering the increase of the
Parent stated share capital by contribution-in-kind (the "Share Capital
                                                          -------------
Increase") with the commercial register (Handelsregister) for the Parent.  At
the Effective Time, the obligation of the parties to effect the Share Exchange
shall be unconditional.

          (b) Exchange Procedures.  Promptly after the Effective Time, and in no
event later than five business days thereafter (unless otherwise agreed to by
each of the parties in writing), the Surviving Corporation shall cause the
Exchange Agent to mail to each holder of record of a Certificate (other than the
Company, the Parent, Merger Sub or any Parent Subsidiary) (i) a letter of
transmittal specifying that delivery shall be effected, and that risk of loss
and title to the Certificates shall pass, only upon proper delivery of the
Certificates (or affidavits of loss in lieu of Certificates) to the Exchange
Agent, in a form and with other customary

                                       5
<PAGE>

provisions reasonably specified by the Parent and the Company, and (ii)
instructions for surrendering the Certificates to the Exchange Agent in exchange
for (A) an ADR representing the number of whole Parent ADSs pursuant to Section
2.2(f), (B) cash in lieu of any fractional Parent ADSs, and (C) any unpaid
dividends and other distributions (if any) pursuant to Section 2.2(c). Upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed, the holder of that Certificate shall
be entitled to receive in exchange (1) an ADR representing that number of whole
Parent ADSs that the holder is entitled to receive under this Article II, (2) a
check in the amount (after giving effect to any required tax withholding) of (x)
any cash in lieu of fractional Parent ADSs plus (y) any unpaid dividends (other
than stock dividends) and any other dividends or other distributions that such
holder has the right to receive under the provisions of this Article II (if
any), and the Certificate so surrendered shall immediately be canceled. No
interest will be paid or accrued on any amount payable upon due surrender of the
Certificates. In the event of a transfer of ownership of shares of Company
Common Stock that is not registered in the transfer records of the Company, an
ADR representing the proper number of Parent ADSs, together with a check for any
cash to be paid upon the surrender of the Certificate and any other dividends or
distributions (if any) in respect of those shares, may be issued or paid to such
a transferee if the Certificate formerly representing such Shares of Company
Common Stock is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect the transfer and to evidence that any applicable
stock transfer taxes have been paid. If any ADRs for shares of Parent ADSs is to
be issued in a name other than that in which the surrendered Certificate is
registered, it shall be a condition of such exchange that the person requesting
such exchange shall pay any transfer or other taxes required by reason of the
issuance of certificates for shares of Parent Common Stock in a name other than
that of the registered holder of the surrendered Certificate, or shall establish
to the satisfaction of the Parent or the Exchange Agent that such tax has been
paid or is not applicable.

          (c) Distributions with Respect to Unexchanged Company Common Stock.
Whenever a dividend or other distribution is declared by the Parent in respect
of Parent Common Stock and the record date for that dividend or other
distribution is at or after the Effective Time, that declaration shall include
dividends or other distributions in respect of all ADSs issuable under this
Agreement.  No dividends or other distributions in respect of the Parent ADSs
shall be paid to any holder of any unsurrendered Certificate until that
Certificate is surrendered for exchange in accordance with this Article II.
Subject to the effect of applicable laws, following surrender of any such
Certificate, there shall be issued or paid to the holder of the ADRs
representing whole shares of Parent ADSs issued in exchange therefor, without
interest, (i) at the time of such surrender, the dividends or other
distributions with a record date at or after the Effective Time and a payment
date on or prior to the date of issuance of such whole Parent ADSs and not
previously paid, and (ii) at the appropriate

                                       6
<PAGE>

payment date, the dividends or other distributions payable with respect to such
whole shares of Parent Common Stock with a record date at or after the Effective
Time but with a payment date subsequent to surrender. For purposes of dividends
or other distributions in respect of Parent ADSs, all Parent ADSs to be issued
pursuant to the Merger shall be deemed issued and outstanding as of the
Effective Time.

          (d) No Further Ownership Rights in Company Common Stock.  Until
surrendered as contemplated by this Section 2.2, each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive the ADR representing Parent ADSs and cash in lieu of any fractional
Parent ADSs, as contemplated by this Section 2.2.  All Parent ADSs, together
with any cash paid under Section 2.2(c) or Section 2.2(f) issued upon the
surrender for or exchange of Certificates in accordance with the terms of this
Agreement, shall be deemed to have been issued in full satisfaction of all
rights pertaining to the shares of Company Common Stock formerly represented by
such Certificates.

          (e) No Further Transfers.  After the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers on the records of the Company of the shares of Company
Common Stock that were outstanding immediately prior to the Effective Time.

          (f) Fractional Shares.

              (i) No ADRs representing fractional Parent ADSs shall be issued
upon the surrender for exchange of Certificates, and such fractional interest
will not entitle its owner to receive dividends or to any other rights of a
holder of Parent ADSs. Notwithstanding any other provision of this Agreement,
each holder of shares of Company Common Stock exchanged pursuant to the Merger
who would otherwise have been entitled to receive a fraction of a Parent ADS
(after taking into account all Certificates delivered by such holder) shall
receive from the Exchange Agent, in accordance with the provisions of this
Article II, a cash payment in lieu of such fractional Parent ADS, as applicable,
representing such holder's proportionate interest, if any, in the net proceeds
from the sale by the Exchange Agent in one or more transactions (which sale
transactions shall be made at such times, in such manner and on such terms as
the Exchange Agent shall determine in its reasonable discretion) on behalf of
all such holders of the aggregate of the fractional Parent ADSs, as applicable,
which would otherwise have been issued (the "Excess Parent ADSs"). The sale of
                                             ------------------
the Excess Parent ADSs by the Exchange Agent shall be executed on the Nasdaq
National Market, at such time the Parent ADSs are quoted on the Nasdaq National
Market, and shall be executed in round lots to the extent practicable. Until the
net proceeds of such sale or sales have been distributed to the holders of
Certificates, the Exchange Agent will hold such proceeds in trust (the "Exchange
                                                                        --------
Trust") for the holders of Certificates. All commissions, transfer taxes and
-----
other out-of-pocket transaction costs, including the

                                       7
<PAGE>

expenses and compensation of the Exchange Agent, incurred in connection with
this sale of the Excess Parent ADSs shall be paid by the Parent. As soon as
practicable after the determination of the amount of cash, if any, to be paid to
holders of Certificates in lieu of any fractional shares of Parent ADSs, the
Exchange Agent shall make available such amounts to such holders of Certificates
without interest. The Exchange Agent shall determine the portion of such net
proceeds to which each holder of shares of Company Common Stock shall be
entitled, if any, by multiplying the amount of the aggregate net proceeds by a
fraction the numerator of which is the amount of the fractional share interest
to which such holder of shares of Company Common Stock is entitled (after taking
into account all shares of Company Common Stock then held by such holder) and
the denominator of which is the aggregate amount of fractional interests to
which all holders of Certificates representing shares of Company Common Stock
are entitled.

          (ii) Notwithstanding the provisions of subsection (i) of this Section
2.2(f), the Parent may elect, at its option exercised prior to the Effective
Time and in lieu of the issuance and sale of Excess Parent ADSs and the making
of the payments contemplated in such subsection, to pay to the Exchange Agent an
amount in cash sufficient for the Exchange Agent to pay each holder of shares of
Company Common Stock an amount in cash equal to the product obtained by
multiplying (A) the fractional interest to which such holder would otherwise be
entitled (after taking into account all shares of Company Common Stock held at
the Effective Time by such holder) by (B) the closing price for a share of
Parent ADSs on the Nasdaq National Market (or, if there is not yet a closing
price for Parent ADSs on such market, the closing price for the Parent Common
Stock underlying such Parent ADS on the Neuer Market (as defined in Section
4.6)) on the first business day immediately following the Effective Time and, in
such case, all references in this Agreement to the cash proceeds of the sale of
the Excess Shares and similar references shall be deemed to mean and refer to
the payments calculated as set forth in this Section 2.2(f)(ii).

          (g) Termination of Exchange Fund.  Any Parent ADSs and any portion of
the Exchange Fund or of dividends or other distributions with respect to the
Parent ADSs deposited by the Parent with the Exchange Agent (including the
proceeds of any investments of those funds) that remains unclaimed by the former
stockholders of the Company within one year after the Effective Time shall be
delivered by the Exchange Agent to a depositary bank deposited by the Parent,
upon demand, whereupon such depositary bank shall hold the Exchange Fund on
behalf of holders of unsurrendered Certificates, and any former stockholders of
the Company who have not theretofore complied with this Article II shall
thereafter look only to such depositary bank for payment of their claim for
Merger Consideration and any dividends and other distributions issuable or
payable pursuant to Section 2.1 and Section 2.2(c) upon due surrender of their
Certificates (or affidavits of loss in lieu of Certificates), in each case,
without any interest and the Parent shall cause the depositary bank to satisfy
such

                                       8
<PAGE>

claim. Notwithstanding the foregoing, none of the Parent, the Surviving
Corporation, the Exchange Agent, the depositary bank or any other person shall
be liable to any former holder of shares of Company Common Stock for any amount
properly delivered to a public official under applicable abandoned property,
escheat or similar laws.

          (h) Lost, Stolen or Destroyed Certificates.  In the event any
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such Certificate to be lost,
stolen or destroyed and the posting by such person of a bond in the form
customarily required by the Parent 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 Parent ADSs, any
unpaid dividends or other distributions and any cash payment in lieu of a
fractional share in respect of that Certificate issuable or payable under this
Article II upon due surrender thereof and deliverable in respect of the shares
of Company Common Stock represented by such Certificate under this Agreement, in
each case, without interest.

          (i) No Liability.  None of the Parent, the Surviving Corporation or
the Exchange Agent shall be liable to any person in respect of any Parent ADSs,
any dividends or distributions with respect to Parent ADSs or any cash from the
Exchange Fund, in each case properly delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

    Section 3.3 No Appraisal Rights. In accordance with Section 262(b)(1) of
the DGCL, no appraisal rights shall be available to holders of shares of Company
Common Stock in connection with the Merger.

    Section 3.4 Adjustments to Prevent Dilution. In the event that prior to the
Effective Time there is a change in the number of shares of Company Common Stock
or shares of Parent Common Stock or securities convertible or exchangeable into
or exercisable for shares of Company Common Stock or shares of Parent Common
Stock issued and outstanding as a result of a distribution, reclassification,
stock split (including a reverse stock split), stock dividend or distribution or
other similar transaction, the Exchange Ratio shall be equitably adjusted to
eliminate the effects of that event.

    Section 3.5 Withholding Rights. Each of the Exchange Agent and Parent shall
be entitled to deduct and withhold from any amounts otherwise payable pursuant
to this Agreement to any holder of a Certificate such amounts as it is required
to deduct and withhold with respect to the making of such payment under the
Code, or any provisions of Law (as defined in Section 3.5(a)(ii) hereof). To the
extent that amounts are so withheld by the Exchange Agent or the Parent, as the
case may be, such withheld amounts shall be treated for purposes of this
Agreement as having been paid to

                                       9
<PAGE>

the holder of a Certificate in respect to which such deduction and withholding
was made by the Exchange Agent or Parent, as the case may be.

    Section 3.6 Treatment of Stock Options/Restricted Stock.

          (a) On June 14, 2000, the Company established a trust, which trust was
funded by the Company promptly after its establishment with shares of the
Company Common Stock in order to satisfy the obligations of the Company under
the outstanding Company Stock Options and the outstanding Company Warrants (as
defined in Section 2.7(a)) (the "Trust").  Prior to the Effective Time, the
                                 -----
Company shall issue and deliver to the Trust such number of shares of Company
Common Stock to satisfy the obligations under all outstanding Company Stock
Options immediately prior to the Effective Time.

          (b) Each Company Stock Option granted prior to the Effective Time and
which remains outstanding immediately prior to the Effective Time shall cease to
represent a right to acquire shares of Company Common Stock and shall be
converted, at the Effective Time, into an option to acquire from the Trust, on
the same terms and conditions as were applicable under the Company Stock Option
(but taking into account any changes thereto, except for any acceleration
thereof, by reason of this Agreement or the transactions contemplated hereby as
may be provided for in the Company's Option Plans, in any award agreement or in
such option), that number of Parent ADSs determined by multiplying the number of
shares of Company Common Stock subject to such Company Stock Option by the
Exchange Ratio, rounded, if necessary, to the nearest whole Parent ADS, at a
price per share (rounded to the nearest one-hundredth of a cent) equal to the
per share exercise price specified in such Company Stock Option divided by the
Exchange Ratio; provided, however, that in the case of any Company Stock Option
to which Section 421 of the Code applies by reason of its qualification under
Section 422 of the Code, the option price, the number of shares subject to such
option and the terms and conditions of exercise of such option shall be
determined in a manner consistent with the requirements of Section 424(a) of the
Code.46

          (c) At the Effective Time, each right of the Company to repurchase
shares of Company Common Stock from optionees pursuant to the Company's Option
Plans ("Repurchase Right") shall be assigned to the Trust, and shall apply to
        ----------------
the Parent ADSs received in exchange for the shares of Company Common Stock
pursuant to Section 2.2 hereof, on the same terms and conditions as were
applicable under the Company's Option Plans (but taking into account any changes
thereto, except for any acceleration thereof, by reason of this Agreement or the
transactions contemplated hereby as may be provided for in the Company's Option
Plans, in any award agreement or in such option).  Prior to the Effective Time,
the

                                       10
<PAGE>

Company shall obtain from holders of the shares of Company Common Stock subject
to Repurchase Rights (such shares being referred to as "Company Restricted
                                                        ------------------
Stock") waivers (as may be reasonably requested by the Parent and in the form
-----
reasonably satisfactory to the Parent) waiving any and all rights to accelerate
the vesting of the shares of Company Common Stock.

          (d) Prior to the Effective Time, the Company shall (i) cause the plan
administrator of each of the Company's Option Plans to determine that the
adjustments pursuant to this Section 2.6 are sufficient to not cause any vesting
in connection with the Merger, and (ii) deliver to the holders of Company Stock
Options and Company Restricted Stock appropriate notices setting forth such
holders' rights (including that (A) such Company Stock Options or Company
Restricted Stock have not accelerated in connection with the Merger, and (B) the
Trust shall satisfy the obligations under the Company Stock Options) and the
agreements evidencing the grants of such Company Stock Options shall continue in
effect on the same terms and conditions (subject to the adjustments required by
this Section 2.6).

          (e) No later than 15 business days following the Effective Time, the
Parent shall file a registration statement on Form S-8 (or any successor or
other appropriate forms), with respect to the Parent ADSs subject to such
Company Stock Options or shares of Company Restricted Stock and shall use
commercially reasonable efforts to maintain the effectiveness of such
registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
Company Stock Options or shares of Company Restricted Stock remain outstanding.

    Section 3.7  Treatment of Warrants.

          (a) Each warrant to purchase shares of Company Common Stock ("Company
                                                                        -------
Warrant") granted prior to the Effective Time and which remains outstanding
-------
immediately prior to the Effective Time shall cease to represent a right to
acquire shares of Company Common Stock and shall be converted, at the Effective
Time, into a warrant to acquire from the Trust, on the same terms and conditions
as were applicable under the Company Warrants, that number of shares of Parent
ADSs determined by multiplying the number of shares of Company Common Stock
subject to such Company Warrant by the Exchange Ratio, rounded, if necessary, to
the nearest whole Parent ADS, at a price per share (rounded to the nearest one-
hundredth of a cent) equal to the per share exercise price specified in such
Company Warrant divided by the Exchange Ratio.  As soon as practicable after the
Effective Time, the Parent shall deliver to the holders of Company Warrants
appropriate notices setting forth such holders' rights and the agreements
evidencing the grants of such Company Warrants shall continue in effect on the
same terms and conditions.

                                       11
<PAGE>

          (b) Prior to the Effective Time, the Company shall deliver to the
holders of Company Warrants appropriate notices setting forth such holders'
rights (including that the Trust shall satisfy the obligations under the Company
Warrants) and the agreements evidencing the grants of such Company Warrants
shall continue in effect on the same terms and conditions (subject to the
adjustments required by this Section 2.7).

                                  ARTICLE IV

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

validly existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, as the case may be, and has the requisite power

its properties and to carry on its business as it is now being conducted.  Each
of the Company and each Company Subsidiary is duly qualified or licensed to do
business, and is in good standing, in each jurisdiction where the character of
the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except for such failures to be

aggregate, have no Material Adverse Effect on the Company.  For purposes of this
Agreement, "Material Adverse Effect on the Company" means any state of affairs
            --------------------------------------
or change that has had, or will have, a material adverse effect on the business,
assets, properties, results of operations or condition (financial or otherwise)
of the Company and the Company Subsidiaries, taken as a whole, or that has
materially impaired or will materially impair the ability of the Company to
perform its obligations under this Agreement or to consummate the Merger and the
other transactions contemplated by this Agreement, except that none of the
following shall be deemed in themselves to constitute a Material Adverse Effect
on the Company:  (i) any change in the market price or trading volume of the
Company Common Stock after the date hereof, (ii) any change in general economic
conditions, (iii) any adverse change affecting the e-commerce industry
generally, and (iv) transaction costs, taxes, accounting changes, integration
costs and other effects that result directly from the announcement or
consummation of the transactions contemplated by this Agreement.

reasonable efforts (through its agents or otherwise) to solicit from its
stockholders proxies in favor of the adoption of this Agreement, and shall take
all other action necessary or advisable to secure Requisite Company Vote, except
to the extent that the Board of Directors of the Company determines in good
faith (after consultation with the Company's counsel) that doing so would be
inconsistent with its fiduciary duties to the Company's stockholders under
applicable Laws.

    Section 6.6 Access to Information; Confidentiality.

          (a) Except as required under any confidentiality agreement or similar
agreement or arrangement to which the Parent or the Company or any of their

regulatory organization with whose rules the parties are required to comply,
from the date of this Agreement to the Effective Time, the Parent and the
Company shall (and shall cause their respective subsidiaries to):  (i) provide
to the other (and its officers, directors, employees, accountants, consultants,

between the Parent and the Company with respect to the information disclosed
under this Section 5.6.

    Section 6.7 No Solicitation.

          (a) The Company agrees that, prior to the Effective Time, it shall
not, and shall not authorize or permit any Company Subsidiaries or any of its or
the Company Subsidiaries' Representatives, directly or indirectly, to (i)
solicit, initiate or encourage any inquiries or the making of any offer or
proposal with respect to (x) any merger, consolidation, share exchange,
recapitalization, business combination or similar transaction, (y) any sale,

for shares of capital stock representing 5% or more of the voting power of the
Company, other than the transactions contemplated by this Agreement (any of the

respective Representatives) that has submitted or proposed to submit any
Takeover Proposal, (iii) provide to any person any non-public information or
data relating to the Company or any Company Subsidiary for the purpose of
facilitating the making of any Takeover Proposal, or (iv) agree to approve or
recommend any Takeover Proposal or otherwise enter into any agreement,
arrangement or understanding requiring it to abandon, terminate or fail to
consummate the Merger or any other transactions contemplated by this Agreement;
provided, however, that if the Board of Directors of the Company determines in
good faith (after consultation with the Company's legal counsel) that failure to
do so would be inconsistent with its fiduciary duties to the Company's
stockholders under applicable Laws, the Company may, in response to any Superior
Proposal, or any Takeover Proposal that would reasonably be expected to lead to
a Superior Proposal, which proposal was not solicited by it and which did not
otherwise result from a breach of this Section 5.7, and subject to providing
prior written notice of its decision to take such action to the Parent and
compliance with the other requirements of this Section 5.7, (A) furnish
information with respect to the Company and the Company Subsidiaries to any
person making a Superior Proposal pursuant to a customary confidentiality
agreement (as determined in good faith by the Company after consultation with
its independent legal counsel), (B) participate in discussions or negotiations
regarding such Superior Proposal or (C) enter into a definitive agreement
providing for the implementation of a Superior Proposal (as defined below) if
the Company or the Board of Directors is simultaneously terminating this

<PAGE>

          (b) In addition to the obligations of the Company set forth in
paragraph (a) of this Section 5.7, the Company shall as promptly as is
practicable advise the Parent orally and in writing of any request for
information relating to any Takeover Proposal, the material terms and conditions
of such request or Takeover Proposal and the identity of the person making such
request or Takeover Proposal.  The Company will keep the Parent informed of the
status (including amendments or proposed amendments) of any such request or
Takeover Proposal.

          (c) Nothing contained in this Section 5.7 shall prohibit the Company
from taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act, or from making any other disclosure
to the Company's stockholders, that is required by applicable Law or by the
Board of Directors' fiduciary duties.

          (d) The Company will immediately cease and cause to be terminated any
existing activities, discussions or negotiations by the Company or its
Representatives with any parties conducted heretofore with respect to any of the
foregoing, and will promptly inform the Representatives of the obligations
undertaken in this Section 5.7.

          (e) The Board of Directors of the Company will not withdraw or modify,
or propose to withdraw or modify, in any manner adverse to the Parent, its
approval or recommendation of this Agreement or the Merger except in connection
with a Superior Proposal and then only upon or after the termination of this
Agreement pursuant to Section 7.1(h) and payment to the Parent of the amounts
referred to in Section 7.3(b).

          (f) For purposes of this Agreement:

               (i) "Superior Proposal" means any bona fide written proposal made

recapitalization, reorganization, liquidation, dissolution or similar
transaction, for consideration to the Company's stockholders consisting of cash
and/or securities, over 50% of the shares of the Company's capital stock then
outstanding on terms which the Board of Directors of the Company determines in
their good faith judgment (after consultation with the Company's financial
advisors), to be more favorable to the Company's stockholders than the Merger
and for which financing, to the extent required, is then committed or which a
majority of the members of the Board of Directors of the Company determines in
their good faith judgment (after such consultation), is likely to be obtained by
such third party.

                                       45

    Section 6.8 Employee Benefits Matters.

          (a) Effective as of the Effective Time and for a one-year period
following the Effective Time, the Parent shall provide, or cause the Surviving
Corporation and its subsidiaries and successors to provide, those persons who,
at the Effective Time, were employees of the Company and its subsidiaries
("Covered Employees"), with benefits and compensation during their continuing
  -----------------
employment that are substantially equivalent, in the aggregate, to the
compensation and benefits provided to such employees as of the date of this
Agreement; provided that the foregoing shall not apply to the Company's 2000
Employee Stock Purchase Plan, which shall be terminated upon or prior to the
Effective Time; provided, further, that nothing herein shall restrict the Parent
or the Surviving Corporation from terminating the employment of any such
employees in accordance with applicable laws and contractual rights, if any, of
such employees.

          (b) The Parent will, or will cause the Surviving Corporation to:  (i)
waive all limitations as to pre-existing conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable to
the Covered Employees under any welfare plan that such employees may be eligible
to participate in after the Effective Time; (ii) provide each such Covered
Employee with credit for any co-payment and deductibles paid prior to the
Effective Time in satisfying any applicable deductible or out-of-pocket
requirements under any welfare plans that such employees are eligible to
participate in after the Effective Time; and (iii) provide each Covered Employee
with credit for purposes of vesting and eligibility for all service with the
Company and its affiliates under each employee benefit plan, program, or
arrangement of the Parent or its affiliates in which such employees are eligible
to participate to the extent such service was credited for similar purposes
under similar plans of the Company or its subsidiaries; provided, however, that
in no event shall the Covered Employees be entitled to any credit to the extent
that it would result in a duplication of benefits with respect to the same
period of service.

consummation of the Offer to pay all amounts provided under all of the Company's
Benefit Plans in accordance with their terms, and (ii) honor and cause the

rights amend or terminate any Benefit Plan in accordance with its terms.

          (d) The Parent and the Company shall jointly determine, no later than
June 30, 2000, an appropriate number of options to be granted between the date

good faith, jointly identify the optionees and determine the amount and terms of
individual grants.

    Section 6.9 Directors' and Officers' Indemnification and Insurance.

          (a) The Parent agrees that the Certificate of Incorporation and By-
laws of the Surviving Corporation will contain provisions with respect to
exculpation and indemnification at least as favorable to employees, agents,
directors or officers of the Company and the Company Subsidiaries (the
"Indemnified Parties") as those provided in the certificate of incorporation or
 -------------------
by-laws of the Company as in effect on the date hereof, which provisions will
not be amended, repealed or otherwise modified for a period of six years from
the Effective Time in any manner that would adversely affect the rights
thereunder of individuals who, immediately prior to the Effective Time, were
directors, officers, employees or agents of the Company, unless such
modification is required by law; provided, however, that in the event any claim
or claims are asserted or made within such six-year period, all rights to
indemnification in respect of any such claim or claims shall continue until
final disposition of any and all such claims.  The foregoing parties are
expressly made third party beneficiaries to the provisions of this Section 5.9.
The Parent also agrees to indemnify all Indemnified Parties to the fullest
extent permitted by applicable law with respect to all acts and omissions
arising out of such individuals' services as officers, directors, employees or
agents of the Company or any of the Company Subsidiaries or as trustees or
fiduciaries of any plan for the benefit of employees, or otherwise on behalf of,
the Company or any of the Company Subsidiaries, occurring prior to the Effective
Time, including the transactions contemplated by this Agreement.  Without
limiting of the foregoing, in the event any such Indemnified Party is or becomes
involved in any capacity in any action, proceeding or investigation in
connection with any matter, including the transactions contemplated by this
Agreement, occurring prior to, and including, the Effective Time, the Parent
will pay as incurred such Indemnified Party's legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith.

          (b) The Parent agrees that the Company and, at and after the Effective
Time, the Surviving Corporation shall cause to be maintained in effect for not
less than six years from the Effective Time the current policies of the
directors' and officers' liability insurance maintained by the Company; provided
that the Surviving Corporation may substitute therefor policies of at least the
same coverage containing terms and conditions which are at least as favorable
and provided that such substitution shall not result in any gaps or lapses in
coverage with respect to matters occurring prior to the Effective Time; and
provided, further, that the Surviving Corporation shall not

                                       47
<PAGE>

be required to pay an annual premium in excess of 175% of the last annual
premium paid by the Company prior to the date of this Agreement and if the
Surviving Corporation is unable to obtain the insurance required by this Section
5.9(b) it shall obtain as much comparable insurance as possible for an annual
premium equal to such maximum amount.

    Section 6.10  Letters of Accountants.

          (a) The Company shall cause to be delivered to the Parent "comfort"

satisfactory to the Company and reasonably customary in scope and substance for
letters delivered by independent public accountants in connection with
transactions contemplated by this Agreement.

conditions provided in this Agreement and to applicable legal requirements, each
of the parties to this Agreement agrees to use commercially reasonable efforts
to take, or cause to be taken, all action, and to do, or cause to be done, and
to assist and cooperate with the other parties to this Agreement in doing, as
promptly as practicable, all things necessary, proper or advisable under
applicable laws and regulations to ensure that the conditions set forth in
Article VI are satisfied and to consummate and make effective the transactions
contemplated by this Agreement. If at any time after the Effective Time any
further action is necessary or desirable to carry out the purposes of this
Agreement, including the execution of additional instruments, the proper
officers and directors of each party to this Agreement shall take all such
necessary or desirable action.

    Section 6.12 Consents; Filings; Further Action.

          (a) Upon the terms and subject to the conditions of this Agreement,
each of the parties to this Agreement shall use commercially reasonable efforts
to (i) take, or cause to be taken, all appropriate action, and do, or cause to
be done, all things necessary, proper or advisable under applicable Law or
otherwise to consummate and make effective the Merger and the other transactions
contemplated by

                                       48
<PAGE>

this Agreement, (ii) obtain from Governmental Entities any consents, licenses,

made by the Parent or the Company or any of their subsidiaries in connection
with the authorization, execution and delivery of this Agreement and the
consummation of the Merger and the other transactions contemplated by this
Agreement, (iii) make all necessary filings, and thereafter make any other
submissions either required or deemed appropriate by each of the parties, with
respect to this Agreement and the Merger and the other transactions contemplated
by this Agreement required under (A) the Securities Act, the Exchange Act and
any other applicable federal or Blue Sky Laws, (B) the HSR Act, (C) the DGCL and
the German Stock Corporation Law (Aktiengesetz), (D) any other applicable Law
and (E) the rules and regulations of the Nasdaq National Market. The parties to
this Agreement shall cooperate and consult with each other in connection with
the making of all such filings, including by providing copies of all such
documents to the nonfiling party and its advisors prior to filing, and none of
the parties will file any such document if any of the other parties shall have
reasonably objected to the filing of such document. No party to this Agreement
shall consent to any voluntary extension of any statutory deadline or waiting
period or to any voluntary delay of the consummation of the Merger and the other
transactions contemplated by this Agreement at the behest of any Governmental
Entity without the consent and agreement of the other parties to this Agreement,
which consent shall not be unreasonably withheld or delayed.

          (b) Without limiting the generality of Section 5.12(a), each party to
this Agreement shall promptly inform the others of any material communication
from the Federal Trade Commission, the Department of Justice or any other
domestic or foreign government or governmental or multinational authority
regarding any of the transactions contemplated by this Agreement.  If any party
or any affiliate thereof receives a request for additional information or
documentary material from any such government or authority with respect to the
transactions contemplated by this Agreement, then such party will endeavor in
good faith to make, or cause to be made, as soon as reasonably practicable and
after consultation with the other party, an appropriate response in compliance
with such request.  The Parent will advise the Company promptly in respect of
any understandings, undertakings or agreements (oral or written) which the
Parent proposes to make or enter into with the Federal Trade Commission, the
Department of Justice or any other domestic or foreign government or
governmental or multinational authority in connection with the transactions
contemplated by this Agreement.  In furtherance and not in limitation of the
foregoing, the Parent shall use commercially reasonable efforts to resolve such
objections, if any, as may be asserted with respect to the transactions
contemplated by this Agreement under any antitrust, competition or trade
regulatory laws, rules or regulations of any domestic or foreign government or
governmental authority or any multinational authority.  Notwithstanding the
foregoing, nothing in this Section 5.12 shall require, or be construed to
require, the Parent or the Company, in connection with the receipt of any
regulatory approval, to proffer to, or agree to (A) sell or hold separate and
agree to sell, divest or to discontinue or limit, before or after the Effective
Time, any assets,

                                       49
<PAGE>

businesses, or interest in any assets or businesses of the Parent, the Company
or any of their respective affiliates (or to the consent to any sale, or
agreement to sell, or discontinuance or limitation by the Parent or the Company,
as the case may be, of any of its assets or businesses) or (B) agree to any
conditions relating to, or changes or restriction in, the operations of any such
asset or businesses which, in either case, could reasonably be expected to
result in a Material Adverse Effect on the Parent or a Material Adverse Effect
on the Company.

          Section 6.13  Plan of Reorganization.  This Agreement is intended to
constitute a "plan of reorganization" within the meaning of Section 1.368-2(g)
of the income tax regulations promulgated under the Code.  From and after the
date of this Agreement and until the Effective Time, each party to this
Agreement shall use commercially reasonable efforts to cause the Merger to
qualify, and will not, without the prior written consent of the parties to this
Agreement, take any actions or cause any actions to be taken which could prevent
the Merger from qualifying, as a reorganization under the provisions of Section
368(a) of the Code.  Following the Effective Time, and consistent with any such
consent, (i) none of the Surviving Corporation, the Parent or any of their
affiliates shall take any action or cause any action to be taken which would
cause the Merger to fail to so qualify as a reorganization under Section 368(a)
of the Code and (ii) the Surviving Corporation and the Parent shall comply with
the record keeping and reporting requirements of Sections 368(a) and 367 of the
Code.

          Section 6.14  Public Announcements.  The initial press release
concerning the Merger shall be a joint press release and, thereafter, the Parent
and Merger Sub and the Company shall consult with each other before issuing any
press release or otherwise making any public statements with respect to this
Agreement or any of the transactions contemplated by this Agreement and shall
not issue any such press release or make any such public statement prior to such
consultation, except to the extent required by applicable Law or the
requirements of the Nasdaq National Market and the Neuer Markt, in which case
the issuing party shall use commercially reasonable efforts to consult with the
other parties before issuing any such release or making any such public
statement.

          Section 6.15  Stock Exchange Listings and De-Listings.  Each of the
Company and the Parent shall use commercially reasonable efforts to cause (i)
the Parent ADSs to be issued in the Merger to be approved for quotation on the
Nasdaq National Market subject to official notice of issuance, prior to the
Effective Time, and (ii) if necessary, the Parent Common Stock underlying the
Parent ADSs to be approved for listing on the Neuer Markt subject to official
notice of issuance, prior to the Effective Time.  The parties shall use their
commercially reasonable efforts to cause the Surviving Corporation to cause the
Company Common Stock to be de-listed from Nasdaq National Market and de-
registered under the Exchange Act as soon as practicable following the Effective
Time.

          Section 6.16  Expenses.  Except as otherwise provided in Section
7.3, whether or not the Merger is consummated, all Expenses incurred in
connection with this Agreement and the Merger and the other transactions
contemplated by this Agreement shall be paid by the party incurring such
Expense, except that Expenses incurred in connection with the filing fee for the
Proxy Statement and printing and mailing the Proxy Materials (other than legal,
accounting, investment and banking, expert and consultant fees and expenses) and
the filing fee under the HSR Act shall be shared equally by the Parent and the
Company.

          Section 6.17  Takeover Statutes; Exon-Florio.  If any Takeover
Statute is or may become applicable to the Merger or the other transactions
contemplated by this Agreement, each of the Parent and the Company and its
respective board of directors shall grant such approvals and take such actions
as are necessary so that such transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement, any necessary filings
are made and otherwise act to eliminate or minimize the effects of such statute
or regulation on such transactions.  In addition, if the Parent so requests, the
Parent and the Company shall cooperate to file a notification pursuant to
Section 721(a) of the Exon-Florio Amendment to the Defense Production Act of
1950

          Section 6.18  Dividends.  The Company shall coordinate with the
Parent the declaration, setting of record dates and payment dates of dividends
on Company Common Stock so that holders of Company Common Stock do not receive
dividends on both Company Common Stock and Parent ADS received in the Merger in
respect of any calendar quarter or fail to receive a dividend on either Company
Common Stock or Parent Common Stock received in the Merger in respect of any
calendar quarter.

          Section 6.19  Control of the Company's Operations.  Nothing
contained in this Agreement shall give the Parent or the Company, directly or
indirectly, rights to control or direct the other party's operations prior to
the Effective Time.

          Section 6.20  Certain Obligations of the Parent.

              (a) Certain obligations of the Parent set forth in this Agreement,
including those obligations designed to survive the consummation of the Share
Exchange, may require additional corporate actions specified in the German Stock
Corporation Law (Aktiengesetz), including Sections 52, 203 and 185 et seq.
thereof, be taken by or with respect to the Parent. As required by law, certain
of such obligations of the Parent shall be incorporated in agreements in
connection with the contributions in kind to the Parent, which agreements shall
be entered into by the Parent and the Exchange Agent in the context of the Share
Exchange pursuant to Sections 52 and 183 et seq. of the German Stock Corporation
Law (Aktiengesetz).

authorized by their board of directors of the Company and by the management
board of the Parent;

          (b) by either the Parent or the Company, if the Effective Time shall
not have occurred on or before December 31, 2000; provided, however, that the
right to terminate this Agreement under this Section 7.1(b) shall not be
available to the party whose failure to fulfill any obligation under this
Agreement shall have been the cause of, or resulted in, the failure of the
Effective Time to occur on or before such date;

          (c) by either the Parent or the Company, if any order, injunction or
decree preventing the consummation of the Merger shall have been entered by any
court of competent jurisdiction or Governmental Entity and shall have become
final and nonappealable;

          (d) by the Parent or the Company, if this Agreement shall fail to
receive the Requisite Company Vote at the Company Stockholders Meeting or any
adjournment or postponement thereof;

          (e) by the Parent, upon a breach of any material representation,
warranty, covenant or agreement on the part of the Company set forth in this
Agreement, or if any representation or warranty of the Company shall have become
untrue, in either case such that the conditions set forth in either of Section
6.2(a) or 6.2(c) would not be satisfied (a "Terminating Company Breach");
                                            --------------------------

                                       55
<PAGE>

provided, however, that, if such Terminating Company Breach is curable by the
Company through the exercise of commercially reasonable efforts and for so long
as the Company continues to exercise such commercially reasonable efforts, the
Parent may not terminate this Agreement under this Section 7.1(e);

          (f) by the Company, upon breach of any material representation,
warranty, covenant or agreement on the part of the Parent set forth in this
Agreement, or if any representation or warranty of the Parent shall have become
untrue, in either case such that the conditions set forth in either of Section
6.3(a) or 6.3(c) would not be satisfied (a "Terminating Parent Breach");
                                            -------------------------
provided, however, that, if such Terminating Parent Breach is curable by the
Parent through commercially reasonable efforts and for so long as the Parent
continues to exercise such commercially reasonable efforts, the Company may not
terminate this Agreement under this Section 7.1(f);

          (g) by the Parent, if (i) the Board of Directors of the Company
withdraws, modifies or changes its approval or recommendation of this Agreement
in a manner adverse to the Parent or shall have resolved to do so, (ii) the
Board of Directors of the Company shall have recommended to the stockholders of
the Company a Takeover Proposal or shall have resolved to do so, or (iii) a
tender offer or exchange offer for 10% or more of the outstanding shares of

business days of such commencement the Board of Directors of the Company shall
have failed to recommend against acceptance of such tender offer or exchange
offer by its stockholders (including by taking no position with respect to the
acceptance of such tender offer or exchange offer by its stockholders);

          (h) by the Company, if the Board of Directors of the Company shall
have concluded in good faith (after consultation with the Company's counsel)
that failure to so terminate would be inconsistent with its fiduciary duties
under applicable Laws and, on or prior to such date, any person or group (other
than the Parent) shall have made a public announcement or otherwise communicated
to the Company and its stockholders with respect to a Superior Proposal;
provided, however, that the Company may not terminate this Agreement pursuant to

the Parent of written notice of such determination of the Company (which written
notice will inform the Parent of the material terms and conditions of the
Superior Proposal); provided, further, however, that such termination under this
Section 7.1(h) shall not be effective until the Company has made payment to the
Parent of the amounts required to be paid pursuant to Section 7.3(b).

have approved the Share Capital Increase.

    Section 8.2 Effect of Termination. Except as provided in Section 8.2, in
the event of termination of this Agreement pursuant to Section 7.1, this
Agreement shall forthwith become void, there shall be no liability under this
Agreement on the part of the Parent or the Company or any of their respective
Representatives, and all rights and obligations of each party to this Agreement
shall cease, subject to the remedies of the parties as set forth in Sections

any party from liability for the breach of any of its representations and
warranties or the breach of any of its covenants or agreements set forth in this
Agreement.

    Section 8.3 Expenses Following Certain Termination Events.

          (a) Except as set forth in this Section 7.3, all Expenses incurred in
connection with this Agreement and the transactions contemplated by this
Agreement shall be paid in accordance with the provisions of Section 5.16.  For
purposes of this Agreement, "Expenses" consist of all out-of-pocket expenses
                             --------
(including, all fees and expenses of counsel, accountants, investment bankers,
experts and consultants to a party to this Agreement and its affiliates)
incurred by a party or on its behalf in connection with or related to the
authorization, preparation, negotiation, execution and performance of this
Agreement, the preparation, printing, filing and mailing of the Proxy Statement
or the Proxy Materials, the solicitation of stockholder approval and all other

Agreement.

          (b) If this Agreement (i) is terminated by the Parent pursuant to
Section 7.1(g), (ii) is terminated by the Company pursuant to Section 7.1(h) or
(iii) is terminated by the Company or the Parent pursuant to Section 7.1(d),
then, subject to the proviso below, the Company shall (x) on the date specified
in the penultimate sentence of this Section 7.3 in the case of a termination
pursuant to Section 7.1(d), or (y) simultaneously with a termination of this
Agreement in the case of a termination pursuant to Section 7.1(g) or 7.1(h), pay
to the Parent (by wire transfer of immediately available funds to an account
designated by the Parent) a termination fee of U.S.$20,000,000 plus, subject to
the last sentence of this Section 7.3, the reimbursement of all of Parent's
actual and documented out-of-pocket expenses (including all investment banking,
legal, accounting and other similar expenses) up to a maximum reimbursable
amount of U.S.$2,000,000 (the "Parent Expenses"); provided, however, that the
                               ---------------
Company shall not be obligated to pay such fee to the Parent if this Agreement
is terminated pursuant to Section 7.1(d) unless (i) at the time of the Company
Stockholders Meeting, the Company has received a bona fide alternative
Acquisition Proposal or a third party has made or publicly announced its
intention to

                                       57
<PAGE>

make a bona fide Acquisition Proposal and (ii) within 12 months after the
termination of this Agreement, the Company enters into a definitive agreement
providing for an alternative Acquisition Proposal with any third party or an
alternative Acquisition Proposal is consummated with any third party. If a
termination fee becomes payable as a result of a termination pursuant to Section
7.1(d), then such termination fee shall be paid promptly (and in any event
within two (2) days of receipt by Company of a written notice from the Parent)
following the earlier of the execution of such definitive agreement providing
for an alternative Acquisition Proposal or the consummation of an alternative
Acquisition Proposal, as the case may be. In addition, in the event the Parent
or the Company terminates this Agreement pursuant to Section 7.1(d) and at the
time of the Company Stockholders Meeting the Company has received a bona fide
alternative Acquisition Proposal or a third party has made or publicly announced
its intention to make a bona fide Acquisition Proposal, the Company shall
promptly on demand reimburse all of the Parent Expenses and thereafter be
obligated to pay the termination fee referred to above only in the event such
fee becomes payable pursuant to this Section 7.3(b).

          (c) Each of the Parent and the Company agrees that the payments
provided for in Section 7.3(b) shall be the sole and exclusive remedy of the
parties upon a termination of this Agreement pursuant to Section 7.1(d), (g) or
(h), as the case may be, and such remedy shall be limited to the payment
stipulated in Section 7.3(b).

          (d) The Company acknowledges that the agreements contained in this
Section 7.3 are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, the Parent would not enter into
this Agreement; accordingly, if the Company fails to pay promptly the amounts
due pursuant to Section 7.3(b), and, in order to obtain such payment, the Parent
commences a suit which results in a judgment against the Company for all or a
portion of such amounts, the Company shall pay to the Parent's Expenses in
connection with such suit, together with interest on the amounts payable to the
Parent at the prime rate of Deutsche Bank in effect on the date such payment was
required to be made.

                                   RECITALS

representing any shares of Company Common Stock or Preferred Stock (other than
shares of Company Common Stock or Preferred Stock owned by the Company or by the
Parent, Merger Sub or any Parent Subsidiary) shall thereafter represent only the
right to receive the Merger Consideration and any distribution or dividend under
Section 2.2(c) in each case without interest.

           Section 3.2  Exchange of Certificates.

          (a) The Share Exchange.  Consistent with the terms of this Agreement,
as soon as practicable following the Effective Time:

              (i)  the Parent shall issue the Parent Common Stock to be
delivered on behalf of the Parent in connection with the Merger and cause the
certificates representing the number of shares of Parent Common Stock (such
Parent

                                       4
<PAGE>

Common Stock, together with any dividends or distributions with respect thereto
to which the holders of Certificates may be entitled pursuant to Section 2.2(c)
and such cash and with the proceeds held in the Exchange Trust (as defined in
Section 2.2(f)), being hereinafter referred to as the "Exchange Fund") to be
                                                       -------------
delivered to the Exchange Agent prior to the Effective Time and reasonably
acceptable to the Company for the benefit of the holders of Certificates, for
exchange in accordance with this Article II, through the Exchange Agent in
exchange for outstanding shares of Company Common Stock or Preferred Stock; and

                (ii) the Exchange Agent shall contribute, on behalf of the
former stockholders of the Company, all of the issued and outstanding shares of
Surviving Corporation Common Stock to the Parent as a transfer in kind (the
"Share Exchange").
 ---------------

          Subject to Section 5.22, the Share Exchange shall be effected in
accordance with Section 52 and Sections 203, 185 et seq. (including in
particular Section 187) of the German Stock Corporation Law (Aktiengesetz), in
each case to the extent each such provision may be applicable, by registering
the increase of the Parent stated share capital from authorized capital by
contribution in kind (the "Share Capital Increase") with the commercial register
                           ----------------------
(Handelsregister) for the Parent and admission of the Parent Common Stock for
quotation on the Neuer Markt.  At the Effective Time, the obligation of the
parties to effect the Share Exchange shall be unconditional.  Schedule
2.2.(a)(ii) sets forth certain actions necessary to effect the Share Capital
Increase and the Share Exchange.

          (b) Exchange Procedures.  Promptly after the Effective Time, the
Surviving Corporation shall cause the Exchange Agent to mail to each holder of
record of a Certificate (other than the Company, the Parent, Merger Sub or any
Parent Subsidiary) (i) a letter of transmittal specifying that delivery shall be
effected, and that risk of loss and title to the Certificates shall pass, only
upon delivery of the Certificates (or affidavits of loss in lieu of
Certificates) to the Exchange Agent, in a form and with other customary
provisions reasonably specified by the Parent, and (ii) instructions for
surrendering the Certificates in exchange for (A) certificates representing
shares of Parent Common Stock  (B) cash in lieu of any fractional shares, and
(C) any unpaid dividends and other distributions (if any) pursuant to Section
2.2(c).  Upon surrender of a Certificate for cancellation to the Exchange Agent
together with such letter of transmittal, duly executed, the holder of that
Certificate shall be entitled to receive in exchange (1) a certificate
representing that number of whole shares of Parent Common Stock that the holder
is entitled to receive under this Article II, (2) a check in the amount (after
giving effect to any required tax withholding) of (x) any cash in lieu of
fractional shares plus (y) any unpaid dividends (other than stock dividends) and
any other dividends or other distributions that such holder has the right to
receive under the provisions of this Article II (if any), and the Certificate so
surrendered shall

                                       5
<PAGE>

immediately be canceled; provided, however, that 20% of such Merger
Consideration shall be delivered into an escrow account pursuant to Section
7.4(d) if required thereby. No interest will be paid or accrued on any amount
payable upon due surrender of the Certificates. In the event of a transfer of
ownership of shares of Company Common Stock or Preferred Stock that is not
registered in the transfer records of the Company, a certificate representing
the proper number of shares of Parent Common Stock, together with a check for
any cash to be paid upon the surrender of the Certificate and any other
dividends or distributions (if any) in respect of those shares, may be issued or
paid to such a transferee if the Certificate formerly representing such shares
of Company Common Stock or Preferred Stock is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect the transfer and to
evidence that any applicable stock transfer taxes have been paid. If any
certificate for shares of Parent Common Stock is to be issued in a name other
than that in which the surrendered Certificate is registered, it shall be a
condition of such exchange that the person requesting such exchange shall pay
any transfer or other taxes required by reason of the issuance of certificates
for shares of Parent Common Stock in a name other than that of the registered
holder of the surrendered Certificate, or shall establish to the satisfaction of
the Parent or the Exchange Agent that such tax has been paid or is not
applicable.

          (c) Distributions with Respect to Unexchanged Company Common Stock.
Whenever a dividend or other distribution is declared by the Parent in respect
of Parent Common Stock and the record date for that dividend or other
distribution is at or after the Effective Time, that declaration shall include
dividends or other distributions in respect of all shares issuable under this
Agreement.  No dividends or other distributions in respect of the Parent Common
Stock shall be paid to any holder of any unsurrendered Certificate until that
Certificate is surrendered for exchange in accordance with this Article II.
Subject to the effect of applicable laws, following surrender of any such
Certificate, there shall be issued or paid to the holder of the certificates
representing whole shares of Parent Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender, the dividends or other
distributions with a record date after the Effective Time and a payment date on
or prior to the date of issuance of such whole Parent Common Stock and not
previously paid, and (ii) at the appropriate payment date, the dividends or
other distributions payable with respect to such whole shares of Parent Common
Stock with a record date after the Effective Time but with a payment date
subsequent to surrender.  For purposes of dividends or other distributions in
respect of Parent Common Stock, all shares of Parent Common Stock to be issued
pursuant to the Merger shall be deemed issued and outstanding as of the
Effective Time.

          (d) No Further Ownership Rights in Company Common Stock.  Until
surrendered as contemplated by this Section 2.2, each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive the certificate representing shares of Parent Common Stock and cash in
lieu of any

                                       6
<PAGE>

fractional shares of Parent Common Stock, as contemplated by this Section 2.2.
All shares of Parent Common Stock, together with any cash paid under Section
2.2(c) or Section 2.2(f) issued upon the surrender for or exchange of
Certificates in accordance with the terms of this Agreement, shall be deemed to
have been issued in full satisfaction of all rights pertaining to the shares of
Company Common Stock or Preferred Stock formerly represented by such
Certificates.

          (e) No Further Transfers.  After the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers on the records of the Company of the shares of Company
Common Stock or Preferred Stock that were outstanding immediately prior to the
Effective Time.

          (f)  Fractional Shares.

               (i) No certificates or scrip representing fractional shares of
Parent Common Stock shall be issued upon the surrender for exchange of
Certificates, and such fractional share interest will not entitle its owner to
vote, to receive dividends or to any other rights of a holder of Parent Common
Stock. Notwithstanding any other provision of this Agreement, each holder of
shares of Company Common Stock or Preferred Stock exchanged pursuant to the
Merger who would otherwise have been entitled to receive a fraction of a share
of Parent Common Stock (after taking into account all Certificates delivered by
such holder) shall receive from the Exchange Agent, in accordance with the
provisions of this Article II, a cash payment in lieu of such fractional shares
of Parent Common Stock, as applicable, representing such holder's proportionate
interest, if any, in the net proceeds from the sale by the Exchange Agent in one
or more transactions (which sale transactions shall be made at such times, in
such manner and on such terms as the Exchange Agent shall determine in its
reasonable discretion) on behalf of all such holders of the aggregate of the
fractional shares of Parent Common Stock, as applicable, which would otherwise
have been issued (the "Excess Parent Shares"). The sale of the Excess Parent
shares by the Exchange Agent shall be executed on the Neuer Markt segment of the
Frankfurt Stock Exchange (the "Neuer Markt") and shall be executed in round lots
to the extent practicable. Until the net proceeds of such sale or sales have
been distributed to the holders of Certificates, the Exchange Agent will hold
such proceeds in trust (the "Exchange Trust") for the holders of Certificates.
All commissions, transfer taxes and other out-of-pocket transaction costs,
including the expenses and compensation of the Exchange Agent, incurred in
connection with this sale of the Excess Parent shares shall be paid by the
Parent. As soon as practicable after the determination of the amount of cash, if
any, to be paid to holders of Certificates in lieu of any fractional shares of
Parent Common Stock, the Exchange Agent shall make available such amounts to
such holders of Certificates without interest. The Exchange Agent shall
determine the portion of such net proceeds to which each holder of shares of
Company

                                       7
<PAGE>

Common Stock or Preferred Stock shall be entitled, if any, by multiplying the
amount of the aggregate net proceeds by a fraction the numerator of which is the
amount of the fractional share interest to which such holder of shares of
Company Common Stock or Preferred Stock is entitled (after taking into account
all shares of Company Common Stock or Preferred Stock then held by such holder)
and the denominator of which is the aggregate amount of fractional interests to
which all holders of Certificates representing shares of Company Common Stock or
Preferred Stock are entitled.

                (ii) Notwithstanding the provisions of subsection (i) of this
Section 2.2(f), the Parent may elect, at its option exercised prior to the
Effective Time and in lieu of the issuance and sale of Excess Parent Shares and
the making of the payments contemplated in such subsection, to pay to the
Exchange Agent an amount in cash sufficient for the Exchange Agent to pay each
holder of shares of Company Common Stock or Preferred Stock an amount in cash
equal to the product obtained by multiplying (A) the fractional interest to
which such holder would otherwise be entitled (after taking into account all
shares of Company Common Stock or Preferred Stock held at the Effective Time by
such holder) by (B) the closing price for a share of Parent Common Stock on the
Neuer Markt on the first business day immediately following the Effective Time
and, in such case, all references in this Agreement to the cash proceeds of the
sale of the Excess Parent Shares and similar references shall be deemed to mean
and refer to the payments calculated as set forth in this Section 2.2(f)(ii).

          (g) Termination of Exchange Fund.  Any shares of Parent Common Stock
and any portion of the Exchange Fund or of dividends or other distributions with
respect to the Parent Common Stock deposited by the Parent with the Exchange
Agent (including the proceeds of any investments of those funds) that remains
unclaimed by the former stockholders of the Company within one year after the
Effective Time shall be delivered by the Exchange Agent to a depositary bank
designated by the Parent, upon demand, whereupon such depositary bank shall hold
the Exchange Fund on behalf of holders of unsurrendered Certificates, and any
former stockholders of the Company who have not theretofore complied with this
Article II shall thereafter look only to such depositary bank for payment of
their Merger Consideration and any dividends and other distributions issuable or
payable pursuant to Section 2.1 and Section 2.2(c) upon due surrender of their
Certificates (or affidavits of loss in lieu of Certificates), in each case,
without any interest.  Notwithstanding the foregoing, none of the Parent, the
Surviving Corporation, the Exchange Agent, the depositary bank or any other
person shall be liable to any former holder of shares of Company Common Stock or
Preferred Stock for any amount properly delivered to a public official under
applicable abandoned property, escheat or similar laws.

          (h) Lost Certificates.  In the event any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed and the posting
by such person

                                       8
<PAGE>

of a bond in the form customarily required by the Parent 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 shares of Parent Common Stock, any unpaid dividends or other
distributions and any cash payment in lieu of a fractional share in respect of
that Certificate issuable or payable under this Article II upon due surrender
thereof and deliverable in respect of the shares of Company Common Stock or
Preferred Stock represented by such Certificate under this Agreement, in each
case, without interest.

          Section 3.3  Dissenters' Rights.  Any issued and outstanding
Company Shares held by any Shareholder who, in accordance with Oregon Law,
dissents from the merger (a "Dissenting Shareholder") and requires appraisal of
                             ----------------------
such Dissenting Shareholder's shares ("Dissenting Shares") shall not be
                                       -----------------
converted or cancelled as described elsewhere in this Section 2, but instead
shall become the right to receive from the Surviving Corporation such
consideration as may be determined to be due to such dissenting Shareholder
pursuant to Oregon Law; provided, however, that Dissenting Shares outstanding at
the Effective and held by a Dissenting Shareholder who shall after the Effective
Time withdraw such Dissenting Shareholder's demand for appraisal or lose such
Dissenting Shareholder's right of appraisal as provided by Oregon Law shall be
deemed to be converted as of the Effective Time into the right to receive the
consideration that would otherwise have been payable in respect thereof if no
dissent had been made.

          Section 3.4  Adjustments to Prevent Dilution.  In the event that
prior to the Effective Time there is a change in the number of shares of Company
Common Stock or Preferred Stock or shares of Parent Common Stock or securities
convertible or exchangeable into or exercisable for shares of Company Common
Stock or Preferred Stock or shares of Parent Common Stock issued and outstanding
as a result of a distribution, reclassification, stock split (including a
reverse stock split), stock dividend or distribution or other similar
transaction, the Exchange Ratio shall be equitably adjusted to eliminate the
effects of that event.

          Section 3.5  Withholding Rights.  Each of the Exchange Agent and
the Parent shall be entitled to deduct and withhold from any amounts otherwise
payable pursuant to this Agreement to any holder of a Certificate such amounts
as it is required to deduct and withhold with respect to the making of such
payment under the Code, or any provisions of Law.  To the extent that amounts
are so withheld by the Exchange Agent or the Parent, as the case may be, such
withheld amounts shall be treated for purposes of this Agreement as having been
paid to the holder of a Certificate in respect to which such deduction and
withholding was made by the Exchange Agent or the Parent, as the case may be.

                                       9
<PAGE>

      Section 3.6  Treatment of Stock Options/Restricted Stock.

          (a) On June 14, 2000, the Company established a trust, which trust was
funded by the Company promptly after its establishment with shares of the
Company Common Stock in order to satisfy the obligations of the Company under
the outstanding Company Stock Options (the "GemStone Systems, Inc. Rabbi
                                            ----------------------------
Trust").  Prior to the Effective Time, the Company shall issue and deliver to
the Trust such number of shares of Company Common Stock to satisfy the
obligations under all outstanding Company Stock Options immediately prior to the
Effective Time.

          (b) Each Company Stock Option granted prior to the Effective Time and
which remains outstanding immediately prior to the Effective Time shall cease to
represent a right to acquire shares of Company Common Stock and shall be
converted, at the Effective Time, into an option to acquire, on the same terms
and conditions as were applicable under the Company Stock Option (but taking
into account any changes thereto, except for any acceleration thereof, by reason
of this Agreement or the transactions contemplated hereby as may be provided for
in the Company's Option Plans, in any award agreement or in such option), that
number of Parent Common Stock determined by multiplying the number of shares of
Company Common Stock subject to such Company Stock Option by the Exchange Ratio,
rounded, if necessary, to the nearest whole share of Parent Common Stock, at a
price per share (rounded to the nearest one-hundredth of a cent) equal to the
per share exercise price specified in such Company Stock Option divided by the
Exchange Ratio; provided, however, that in the case of any Company Stock Option
to which Section 421 of the Code applies by reason of its qualification under
Section 422 of the Code, the option price, the number of shares subject to such
option and the terms and conditions of exercise of such option shall be
determined in a manner consistent with the requirements of Section 424(a) of the
Code.  In the event that American Depositary Shares representing Parent Common
Stock ("Parent ADSs") are quoted on NASDAQ and registered under the Exchange Act
        -----------
(as defined below), such Company Stock Options shall be deemed exercisable for
Parent ADSs (taking into account the ratio of Parent ADSs to Parent Common
Stock).

          (c) Prior to the Effective Time, the Company shall deliver to the
holders of Company Stock Options appropriate notices setting forth such holders'
rights (including that such Company Stock Options have not accelerated in
connection with the Merger) and the agreements evidencing the grants of such
Company Stock Options shall continue in effect on the same terms and conditions
(subject to the adjustments required by this Section 2.6).

          (d) Promptly after a registered public offering of the Parent's equity
securities in the United States following the Effective Time, the Parent shall
file a registration statement on Form S-8 (or any successor or other appropriate
forms), with respect to the Parent ADSs subject to such Company Stock Options
and shall use commercially reasonable efforts to maintain the effectiveness of
such registration statement or registration

                                       10
<PAGE>

statements (and maintain the current status of the prospectus or prospectuses
contained therein) for so long as such Company Stock Options remain outstanding.
With respect to those individuals who subsequent to the Merger will be subject
to the reporting requirements under Section 16(a) of the Securities Exchange Act
of 1934, as amended (together with the rules and regulations promulgated
thereunder, the "Exchange Act"), where applicable, the Parent shall administer
                 ------------
the Company's Option Plans in a manner consistent with the exemptions provided
by Rule 16b-3 promulgated under the Exchange Act.

          Section 3.7  Exchange of Affiliate Debt.    On the Closing Date, all
indebtedness of the Company or any of the Company Subsidiaries owed to the
Shareholder or to any affiliate of the Shareholder (in such capacity, each an
"Affiliated Lender"), aggregating $7,067,900 on the date hereof, and including
------------------
amounts to be advanced under Section 5.24, shall be assigned and transferred by
such Affiliated Lender to the Parent in exchange for shares of Parent Common
Stock having a value (based upon a fixed value per share of Parent Common Stock
of $114.78) equal to the amount of principal of and accrued but unpaid interest
on such indebtedness to Affiliated Lenders.

validly existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, as the case may be, and has the requisite power
and authority and all necessary governmental approvals to own, lease and operate
its properties and to carry on its business as it is now being conducted.  Each
of the Company and each Company Subsidiary is duly qualified or licensed to do
business, and is in good standing, in each jurisdiction where the character of
the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except as set forth in Section

be expected to result in a Material Adverse Effect on the Company (as defined
below)).

transaction contemplated by this Agreement or otherwise), whether formal or
informal, oral or written, under which any employee or former employee of the
Company has any present or future right to benefits or under which the Company
has any present or future liability. All such plans, agreements, programs,
policies and arrangements shall be collectively referred to as the "Benefit
                                                                    -------

          (e) Each Benefit Plan is in material compliance with all applicable
Law.  Each Benefit Plan which is intended to qualify under Section 401(a) of the
Code has been issued a favorable determination letter by the Internal Revenue
Service and has not been amended in a manner, and no event has occurred since
such date, which would cause any such plan to fail to remain so qualified.  Each
Benefit Plan that requires registration with a relevant Governmental Entity has
been so registered.

          (f) Except as set forth on Section 3.10(f) of the Company Disclosure
Letter, there are no actions, liens, suits or Claims pending or threatened

which the Company has or could reasonably be expected to have any direct or
indirect actual or contingent material liability.

          (g) Each Benefit Plan which is a "group health plan" (as defined in
Section 607(1) of ERISA) is in material compliance with the provisions of the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, the Health
Insurance Portability and Accountability Act and any other applicable Law.

          (h) There are no (i) Benefit Plans maintained by the Company pursuant
to which welfare benefits are provided to current or former employees beyond
their retirement or other termination of service, other than coverage mandated
by applicable Law, the cost of which is fully paid by the current or former
employees or their dependents; or (ii) unfunded Benefit Plan obligations with
respect to any employee of the Company which are not fairly reflected by
reserves shown on the Company's financial statements for March 31, 2000.

          (i) The consummation of the transactions contemplated by this
Agreement will not (i) entitle any current or former employee of the Company to
severance pay, unemployment compensation or any similar payment, (ii) except as

meaning of Section 502(l) of ERISA as to which the Company has or reasonably
could be expected to have any direct or indirect actual material liability.

          (j) No Benefit Plan is a "multiemployer plan" or "multiple employer

thereunder.

or any "party in interest" (as defined in Section 3(18) of ERISA), has engaged
in any non-exempt prohibited transaction (within the meaning of Section 4975 of
the Code or Section 406 of ERISA) which could reasonably be expected to result
in any material liability to the Company.

          (l) None of the employees is represented by a union, and no union
organizing efforts have been conducted within the last five years or are now
being conducted.  The Company does not currently have, nor to knowledge of the
Company, is there now threatened, a strike, picket, work stoppage, work slowdown

          Section 5.1  Organization and Qualification; Subsidiaries.

          (a) The Parent has been duly organized and is validly existing and in
good standing under the laws of its jurisdiction of incorporation or
organization, and has the requisite power and authority and all necessary
governmental approvals to own, lease and operate its properties and to carry on
its business as it is now being conducted.  Each of the Parent and the
subsidiaries of the Parent (each a

<PAGE>

"Parent Subsidiary") is duly qualified or licensed to do business, and is in
 -----------------
good standing, in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing necessary, except for such failures to be so qualified or licensed
and in good standing that, individually or in the aggregate, have not resulted
and could not reasonably be expected to result in a Material Adverse Effect on
the Parent. For purposes of this Agreement, "Material Adverse Effect on the
                                             ------------------------------
Parent" means any change in or effect on (or an event or circumstance involving
------
a prospective change in or effect on) the business, assets, properties, results
of operations or condition (financial or otherwise) of the Parent or any Parent
Subsidiaries that is or could reasonably be expected to be materially adverse to
the Parent and the Parent Subsidiaries, taken as a whole, or that could
reasonably be expected to materially impair the ability of the Parent to perform
its obligations under this Agreement or to consummate the Merger and the other
transactions contemplated by this Agreement.

          (b) Section 4.1 of the disclosure letter previously delivered by the
Parent to the Company (the "Parent Disclosure Letter") sets forth a complete and
                            ------------------------

organization and the ownership or other interest therein of the Parent and of
each other Parent Subsidiary.  Neither the Parent nor any Parent Subsidiary
holds any interest in any person other than the Parent Subsidiaries so listed.

          Section 5.2  Charter Documents.    The copies of the Parent's
articles of association (Satzung) and management board (Vorstand) Rules of
Procedure (Geschaftsordnung), each as amended through the date of this
Agreement, that have been furnished to the Company, are complete and correct
copies of those documents.  The Parent is not in violation of any of the

          (c) As of May 19, 2000, (i) 27,311,184 shares of Parent Common Stock
were issued and outstanding, all of which were validly issued and are fully
paid, nonassessable and not subject to preemptive rights, (ii) the authorized
capital I of the Parent consisted of 10,337,589 shares of Parent Common Stock,
(iii) the authorized capital II of the Parent consisted of 2,600,000 shares of

voting securities of the Parent were issued, reserved for issuance or
outstanding and, since such date, no shares of capital stock or other voting
securities or options in respect thereof have been issued except upon the
exercise of the Parent Stock Options outstanding on such date.  On May 26, 2000,
the Parent's shareholders authorized the issuance of convertible bonds in an
aggregate principal amount of Euro 2,600,000 which may be used in connection
with employee participation schemes and the Parent's shareholders resolved to

<PAGE>

bearer shares and authorized the management board to purchase own shares of up
to 10% of the share capital for a time period of 18 months.  No other increase
of share capital has been resolved since May 19, 2000.  The Parent has
sufficient authorized share capital to proceed with the Share Capital increase
as set forth in this Agreement.

          (b) Between December 31, 1999 and the date of this Agreement, no
options to purchase shares of Parent Common Stock ("Parent Stock Options") have

under agreements or arrangements described in Section 4.3(b) of the Parent
Disclosure Letter, there are no options, warrants, calls, conversion rights,
stock appreciation rights, redemption rights, repurchase rights or other rights,
agreements, arrangements or commitments of any character to which the Parent is
a party or by which the Parent is bound relating to the issued or unissued
capital stock of the Parent or any Parent Subsidiary or obligating the Parent or
any Parent Subsidiary to issue or sell any shares of capital stock of, other
equity interests in, or securities exchangeable for or convertible in the
capital stock or other equity interest in the Parent or any Parent Subsidiary.
None of the Parent Stock Options which are subject to vesting will vest as a
result of the consummation of the Merger.

          (c) Subject to Section 5.22, the shares of Parent Common Stock to be
delivered in connection with the Merger have been duly authorized by all
necessary corporate action, and when issued in accordance with this Agreement,
will be validly issued, fully paid, nonassessable and will not be subject to
preemptive rights.  Each outstanding share of capital stock of each Parent
Subsidiary is duly authorized, validly issued, fully paid, nonassessable and not
subject to preemptive rights and each such share owned by the Parent or a Parent
Subsidiary is free and clear of all Liens, except where failure to own such
shares free and clear, individually or in the aggregate, has not resulted and
could not reasonably be expected to result in a Material Adverse Effect on the
Parent.

          Section 5.4  Authority.

          (a) The Parent has all necessary corporate power and authority to
execute and deliver this Agreement and, subject to compliance with Section 52 of
the German Stock Corporation Law (Aktiengesetz), the resolutions of the

             (iii) result in any breach of or constitute a default (or an event

cancellation of, or result in the creation of a Lien on any property or asset of
the Parent or any Parent Subsidiary under, any Contract to which the Parent or
any Parent Subsidiary is a party or by which any of them or their assets or
properties is or may be bound or affected, except for any such breaches,

correct and complete list in all material respects of Contracts to which the

          Section 5.10  Litigation.  Except as disclosed in Section 4.10 of
the Parent Disclosure Letter, there is no Claim pending or, to the knowledge of
the Parent, threatened against the Parent or any Parent Subsidiary before any
Governmental Entity that, individually or in the aggregate, has resulted or
could reasonably be expected to result in a Material Adverse Effect on the
Parent.  Neither the Parent nor any Parent Subsidiary is subject to any
outstanding order, writ, injunction or decree which, individually or in the
aggregate, has resulted or could reasonably be expected to result in a Material
Adverse Effect on the Parent.

          Section 5.11  Intellectual Property.  To the knowledge of the
Parent, the Parent owns, or is validly licensed or otherwise has the right to
use all Intellectual Property that is material to the conduct of the business of
the Parent and the Parent Subsidiaries, taken as a whole.  To the knowledge of
the Parent, as of the date of this Agreement, no suits, actions or proceedings
are pending, and no person has threatened in a writing delivered to the Parent
since January 1, 1999 to commence any suit, action or proceeding, alleging that
the Parent or any Parent Subsidiaries are infringing the rights of any person
with regard to any Intellectual Property, except for suits, actions or
proceedings that, individually or in the aggregate, would not have a Material
Adverse Effect on the Parent.  To the knowledge of the Parent, no person is
infringing the Intellectual Property rights of the Parent or any Parent
Subsidiary, except for infringements which, individually or in the aggregate,
would not have a Material Adverse Effect on the Parent.

          Section 5.12  Taxes.  Except to the extent that failure to do so,
individually or in the aggregate, has not resulted and could not reasonably be
expected to result in a Material Adverse Effect on the Parent, the Parent and
the Parent Subsidiaries have filed all Tax returns and reports to be filed by
them and have paid, or established adequate reserves for, all Taxes required to
be paid by them.  Except as, individually or in the aggregate, has not resulted
and could not reasonably be expected to result in a Material Adverse Effect on
the Parent, no deficiencies for any Taxes have been proposed, asserted or
assessed against the Parent or any Parent Subsidiaries, and no requests for
waivers of the time to assess any such Taxes are pending.

          Section 5.13  Brokers.  No broker, finder or investment banker
other than the Parent Financial Advisor is entitled to any brokerage, finder's
or other fee or commission in connection with the Merger or the other
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of the Parent.  Prior to the date of this Agreement, the Parent has
made available to the Company a complete and correct copy of all agreements
between the Parent and the Parent Financial Advisor under which the Parent
Financial Advisor would be entitled to any payment relating to the Merger or
such other transactions.

          Section 5.14  Compliance with Laws.  The Parent is in compliance
with all applicable Laws except where failure to so comply would not have a
Material Adverse Effect on the Parent.

          Section 5.15  Parental Approval.  Apart from the Requisite Parent
Approval and the resolutions of the management board and the supervisory board
of the Parent with respect to the listing of the Parent Common Stock for
quotation on the Neuer Markt, no other resolution of the general meeting, the
management board or the supervisory board of the Parent is necessary for the
Parent to perform its obligations under this Agreement, and to consummate the
Merger and the other transactions contemplated by this Agreement.  The quotation
of the Parent Common Stock on the

                                       42
<PAGE>

Neuer Markt shall be for unrestricted trading apart from any requirements
resulting from the Stockholders Agreement between the Parent and the Shareholder
("the Neuer Markt Quotation").

          Section 5.16  Full Disclosure.  No Document delivered by or on
behalf of the Parent in connection with this Agreement contains an untrue
statement of a material fact or omits to state a material fact required to be
stated there in or necessary to make the statements made, in the context in
which made, not materially false or misleading.

receipt of advice to such effect from independent legal counsel (who may be the
Company's regularly engaged independent legal counsel).

          Section 6.6  Access to Information; Confidentiality.

the Company or a Company Subsidiary, including by way of a tender offer or
exchange offer by any person (other than the Company or a Company Subsidiary)

          (a) Effective as of the Effective Time of the Merger and for a one-

Company and its subsidiaries ("Covered Employees"), with benefits and
                               -----------------
compensation during their continuing employment that are substantially
comparable, in the aggregate, to the

<PAGE>

compensation and benefits provided to such employees as of the date of this
Agreement; provided that nothing herein shall restrict the Parent or the
Surviving Corporation from terminating the employment of any such employees in
accordance with applicable laws and contractual rights, if any, of such
employees.

          (b) The Parent will, or will cause the Surviving Corporation to:  (i)

with credit for purposes of vesting and eligibility for all service with the
Company and its affiliates under each employee benefit plan, program, or
arrangement of the Parent or its affiliates in which such employees are eligible
to participate to the extent such service was credited for similar purposes
under similar plans of the Company or its subsidiaries; provided, however, that
in no event shall the Covered Employees be entitled to any credit to the extent
that it would result in a duplication of benefits with respect to the same
period of service.

          (c) The Parent shall (i) cause the Surviving Corporation after the
consummation of the Offer to pay all amounts provided under all of the Company's
Benefit Plans in accordance with their terms, and (ii) honor and cause the

with respect to any Benefit Plans which become effective as a result of such
change in control in accordance with their terms, subject in each case to all
rights amend or terminate any Benefit Plan in accordance with its terms.

          (d) The Parent and the Company shall endeavor in good faith to
determine, no later than June 30, 2000, an appropriate number of options to be
granted (including the identity of the optionees and the amount of individual
grants) between the date of this Agreement and the Effective Time.

          Section 6.9  Directors' and Officers' Indemnification and Insurance.

          (a) The Parent agrees that all rights to indemnification now existing

Company Subsidiaries (the "Indemnified Parties") as provided in their respective
                           -------------------
charters or by-laws, in an agreement between an Indemnified Party and the
Company or one of the Company Subsidiaries, or otherwise in effect on the date
of this Agreement shall survive the Merger and shall continue in full force and
effect for a period of not less than six years from the Effective Time; provided
that in the event

                                       49
<PAGE>

any claim or claims are asserted or made within such six-year period, all rights
to indemnification in respect of any such claim or claims shall continue until
final disposition of any and all such claims. The Parent also agrees to
indemnify all Indemnified Parties to the fullest extent permitted by applicable
law with respect to all acts and omissions arising out of such individuals'
services as officers, directors, employees or agents of the Company or any of
the Company Subsidiaries or as trustees or fiduciaries of any plan for the
benefit of employees, or otherwise on behalf of, the Company or any of the
Company Subsidiaries, occurring prior to the Effective Time, including the
transactions contemplated by this Agreement. Without limiting of the foregoing,
in the event any such Indemnified Party is or becomes involved in any capacity
in any action, proceeding or investigation in connection with any matter,
including the transactions contemplated by this Agreement, occurring prior to,
and including, the Effective Time, the Parent will pay as incurred such
Indemnified Party's legal and other expenses (including the cost of any
investigation and preparation) incurred in connection therewith.

          (b) The Parent agrees that the Company and, from and after the
Effective Time, the Surviving Corporation shall cause to be maintained in effect

and officers' liability insurance in such amounts and on such terms and
conditions as are customary for companies similar to the Company.

          Section 6.10  Letters of Accountants.

          (a) The Company shall use its reasonable best efforts to cause to be
delivered to the Parent "comfort" letters of Ernst & Young, the Company's
independent public accountants, as to the Parent's financial information, dated

substance reasonably satisfactory to the Parent and reasonably customary in

connection with transactions contemplated by this Agreement.

          (b) The Parent shall use its reasonable best efforts to cause to be

the case of the Parent, consistent with the fiduciary duties of the Parent's
Management Board and Supervisory Board, and to assist and cooperate with the
other parties to this Agreement in doing, as promptly as practicable, all things
necessary, proper or advisable under applicable laws and regulations to ensure
that the conditions set forth in Article VI are satisfied and to consummate and
make effective the transactions contemplated by this Agreement. If at any time
after the Effective Time any further action is necessary or desirable to carry
out the purposes of this Agreement, including the execution of additional
instruments, the proper officers and directors of each party to this Agreement
shall take all such necessary or desirable action.

          Section 6.12  Consents; Filings; Further Action.

          (a) Upon the terms and subject to the conditions of this Agreement,
each of the parties to this Agreement shall use its reasonable best efforts to
(i) take, or cause to be taken, all appropriate action, and do, or cause to be
done, all things necessary, proper or advisable under applicable Law or
otherwise to consummate and make effective the Merger and the other transactions
contemplated by this Agreement, (ii) obtain from Governmental Entities any
consents, licenses, permits, waivers, approvals, authorizations or orders
required to be obtained or made by the Parent or the Company or any of their
subsidiaries in connection with the authorization, execution and delivery of
this Agreement and the consummation of the Merger and the other transactions
contemplated by this Agreement, (iii) make all necessary filings, and thereafter
make any other submissions either required or deemed appropriate by each of the

HSR Act, (C) the ORS and the German Stock Corporation Law (Aktiengesetz), (D)
any other applicable Law and (E) the rules and regulations of the Neuer Markt.
The parties to this Agreement shall cooperate and consult with each other in
connection with the making of all such filings, including by providing copies of
all such documents to the nonfiling party and its advisors prior to filing, and
none of the parties will file any such document if any of the other parties
shall have reasonably objected to the filing of such document.  No party to this
Agreement shall consent to any voluntary extension of any statutory deadline or
waiting period or to any voluntary delay of the consummation of the Merger and
the other transactions contemplated by this Agreement at the behest of any
Governmental Entity without the consent and agreement of the other parties to
this Agreement, which consent shall not be unreasonably withheld or delayed.

          (b) Without limiting the generality of Section 5.15(a), each party to
this Agreement shall promptly inform the others of any material communication
from the Federal Trade Commission, the Department of Justice or any other
domestic or foreign government or governmental or multinational authority

                                       51
<PAGE>

regarding any of the transactions contemplated by this Agreement.  If any party
or any affiliate thereof receives a request for additional information or
documentary material from any such government or authority with respect to the
transactions contemplated by this Agreement, then such party will endeavor in
good faith to make, or cause to be made, as soon as reasonably practicable and
after consultation with the other party, an appropriate response in compliance
with such request.  The Parent will advise the Company promptly in respect of
any understandings, undertakings or agreements (oral or written) which the
Parent proposes to make or enter into with the Federal Trade Commission, the
Department of Justice or any other domestic or foreign government or
governmental or multinational authority in connection with the transactions
contemplated by this Agreement.  In furtherance and not in limitation of the
foregoing, the Parent shall use its reasonable best efforts to resolve such
objections, if any, as may be asserted with respect to the transactions
contemplated by this Agreement under any antitrust, competition or trade
regulatory laws, rules or regulations of any domestic or foreign government or
governmental authority or any multinational authority.  Notwithstanding the
foregoing, nothing in this Section 5.15 shall require, or be construed to
require, the Parent or the Company, in connection with the receipt of any
regulatory approval, to proffer to, or agree to (A) sell or hold separate and
agree to sell, divest or to discontinue or limit, before or after the Effective
Time, any assets, businesses, or interest in any assets or businesses of the
Parent, the Company or any of their respective affiliates (or to the consent to

the Company, as the case may be, of any of its assets or businesses) or (B)
agree to any conditions relating to, or changes or restriction in, the
operations of any such asset or businesses which, in either case, could
reasonably be expected to result in a Material Adverse Effect on the Parent or a
Material Adverse Effect on the Company or to materially and adversely impact the

          Section 6.13  Plan of Reorganization.  This Agreement is intended to

date of this Agreement and until the Effective Time, each party to this
Agreement shall use its reasonable best efforts to cause the Merger to qualify,
and will not, without the prior written consent of the parties to this
Agreement, knowingly take any actions or cause any actions to be taken which
could prevent the Merger from qualifying, as a reorganization under the
provisions of Section 368(a) of the Code.  Following the Effective Time, and
consistent with any such consent, none of the Surviving Corporation, the Parent
or any of their affiliates shall knowingly take any action or knowingly cause
any action to be taken which would cause the Merger to fail to so qualify as a
reorganization under Section 368(a) of the Code.

          Section 6.14  Public Announcements.  The initial press release
concerning the Merger shall be a joint press release and, thereafter, the Parent

<PAGE>

Merger Sub and the Company shall consult with each other before issuing any
press release or otherwise making any public statements with respect to this
Agreement or any of the transactions contemplated by this Agreement and shall
not issue any such press release or make any such public statement prior to such
consultation, except to the extent required by applicable Law or the
requirements of the Neuer Markt, in which case the issuing party shall use its
reasonable best efforts to consult with the other parties before issuing any
such release or making any such public statement.

          Section 6.15  Stock Exchange Listings.  The Parent shall use its
reasonable best efforts to cause the shares of the Parent Common Stock to be
approved for listing on the Neuer Markt subject to official notice of issuance,
prior to the Effective Time and the Parent anticipates that the Parent ADSs will
be approved for quotation on NASDAQ.

          Section 6.16  Expenses.  Except as otherwise provided in Section
7.3, whether or not the Merger is consummated, all Expenses (as defined in
Section 7.3(a)) incurred in connection with this Agreement and the Merger and
the other transactions contemplated by this Agreement shall be paid by the party
incurring such Expense, except that Expenses incurred in connection with the
filing fee for the filing fee under the HSR Act shall be shared equally by the
Parent and the Company.

          Section 6.17  Takeover Statutes.  If any Takeover Statute is or may
become applicable to the Merger or the other transactions contemplated by this
Agreement, each of the Parent, Merger Sub and the Company and its respective
board of directors shall grant such approvals and take such actions as are
necessary so that such transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise act to
eliminate or minimize the effects of such statute or regulation on such
transactions.

          Section 6.18  Dividends.  The Company shall coordinate with the
Parent the declaration, setting of record dates and payment dates of dividends
on Company Common Stock so that holders of Company Common Stock do not receive
dividends on both Company Common Stock and Parent Common Stock received in the
Merger in respect of any calendar quarter or fail to receive a dividend on
either Company Common Stock or Parent Common Stock received in the Merger in
respect of any calendar quarter.

          Section 6.19  Control of the Company's Operations.  Nothing
contained in this Agreement shall give the Parent or the Company, directly or

          Section 6.20  Fairness Hearing.

             (a) As soon as practicable after the signing of this Agreement, the
Company, Merger Sub and the Parent shall prepare and file with the Oregon
Director of the Department of Consumer and Business Services (the "Director")
                                                                   --------
the documents required by the Director to hold a hearing on the fairness of the
terms of the Merger and this Agreement pursuant to the ORS (the "Fairness
                                                                 --------
Hearing").  Each of the Company and the Parent shall use its reasonable best
-------
efforts to ensure that (i) holders of Company Common Stock have received
adequate notice of the Fairness Hearing, (ii) holders of Company Common Stock
have the right to appear at the Fairness Hearing, and (iii) the Director is
advised that the Company and the Parent will rely on the exemption provided by
Section 3(a)(10) of the Securities Act based on the Director's approval of the
transactions contemplated hereby.  The Company shall prepare with the assistance
of the Parent, and the Company will distribute, any information statement to the
holders of Company Common Stock as may be required by the Director or applicable
Oregon Law.  Each of the Company, the Shareholder, Merger Sub and the Parent
shall use its reasonable best efforts to cause the Director to approve the
fairness of terms of the Merger and this Agreement.  Following the approval by
the Director, the Company shall use its reasonable best efforts to cause to be
delivered to the Parent an opinion from Tonkon Torp LLP, counsel to the Company,
dated and delivered as of the Effective Time, and addressed to the Parent to the
effect that the Fairness Hearing is a proceeding by an official or agency of a
state governmental authority expressly authorized by law to grant the approval
of the exchange of securities pursuant to Section 3(a)(10) of the Securities
Act.

             (b) If the Director either (i) declines to hold the Fairness
Hearing, or (ii) after holding the Fairness Hearing determines not to issue an
order permitting the issuance of Parent Common Stock in a transaction exempt
from registration under the Securities Act pursuant to Section 3(a)(10) of the
Securities Act, then the Parent may (but is under no obligation to) (A) prepare
and file a Registration Statement to register under the Securities Act the
shares of Parent Common Stock to be issued in connection with the Merger (or
Parent ADSs representing Parent Common Stock) or, (B) seek an exemption from the
registration requirements under the Securities Act for the issuance of the
shares of Parent Common Stock to be issued (directly or in the form of Parent
ADSs) in connection with the Merger. In the event the Parent files such
Registration Statement or seeks such exemption, the Company shall furnish
promptly such information concerning the business, properties, Contracts,
assets, liabilities, personnel and other aspects of the Company and the Company
Subsidiaries as the Parent or the Parent's Representatives may reasonably
request in connection therewith. In the event the Parent does not file a
Registration Statement within 60 days of the occurrence of either event set
forth in clause (i) or (ii) of this Section 5.20(b) the Company may terminate
this agreement pursuant to Section 7.1(h).

Contracts, assets, liabilities, personnel and other aspects of the Company and
the Company Subsidiaries as the Parent or the Parent's Representatives may
reasonably request in connection with the Parent's preparation and filing of any
proxy statement, Registration Statement under the Securities Act, Exchange Act
and/or Blue Sky Laws or any other filings that the Parent may be required to
make under U.S. or German Laws or stock exchange rules (whether or not in
connection with the Merger) (collectively, "Parent Filings").  The information
supplied by the Company for inclusion in such Parent Filings shall not contain
any untrue statement of a material fact or fail to state any material fact
required to be stated in such Parent Filings or necessary in order to make the
statements in such Parent Filings not misleading, including any information that
Parent should set forth in an amendment or supplement to such Parent filings.

Law (Aktiengesetz), including Section 52 and Sections 203, 185 et seq. thereof,
be taken by or with respect to the Parent.  As required by law, certain of such
obligations of the Parent shall be incorporated in agreements in connection with

voting securities of the Company beneficially owned by it to be counted as

beneficially owned or held of record by the Shareholder or as to which the
Shareholder has, directly or indirectly, the right to vote or direct the voting,
in favor of the approval and adoption of, and against any action or agreement
that would compete, impede, or interfere with the approval and adoption of, the
Merger Agreement, the Merger and any action required in furtherance thereof.

          (b) At the Closing, the Shareholder shall enter into a Stockholders
Agreement with the Parent in the form attached as Exhibit A, pursuant to which

credit lines or enter into a bridge loan substantially in the form attached as
Exhibit B.  At closing all outstanding debt owed to the Shareholder shall be

all funding obligations of the Shareholder and any related lending facilities
will terminate.

          Section 6.25  Security of Shareholder Obligation.  The Company
agrees that, prior to the Effective Time, it shall establish, in a manner

an unrestricted ADR program and has a class of Parent Common Stock registered
under the Exchange Act, Parent will use its reasonable efforts to allow the
Parent Common Stock issued pursuant to this Agreement to be deposited in the

or otherwise in respect of (i) any inaccuracy in or any breach of any
representation, warranty, covenant or agreement of the Shareholder contained in
this Agreement or in any documents delivered by the Shareholder pursuant to this
Agreement, or (ii) any breach of any covenant or agreement of such Shareholder
contained in Article V.

               (b) Notice and Opportunity to Defend.
                   --------------------------------

                   (i) All claims by the Parent under this Section 7.4 shall be
asserted and resolved as follows: Promptly after receipt by the Parent of notice
of any Claim or circumstances which, with the lapse of time, would or might give
rise to a Claim or the commencement (or threatened commencement) of a Claim
including any action, proceeding or investigation (an "Asserted Liability") that
                                                       ------------------
may result in a Loss, the Parent shall give notice thereof (the "Claims Notice")
                                                                 -------------
to the Shareholder. The Claims Notice shall describe the Asserted Liability in
reasonable detail, and shall indicate the amount (estimated, if necessary and to
the extent feasible) of the Loss that has been or may be suffered by the Parent.

                   (ii) The Shareholder may elect to compromise or defend, at
its own expense and by its own counsel, any Asserted Liability. If the
Shareholder elects to compromise or defend such Asserted Liability, it shall
within 30 days (or sooner, if the nature of the Asserted Liability so requires)
notify the Parent of its intent to do so, and the Parent shall cooperate, at the
expense of the Shareholder, in the compromise of, or defense against, such
Asserted Liability. If the Shareholder elects not to compromise or defend the
Asserted Liability, fails to notify the Parent of its election as herein
provided or contests its obligation to indemnify under this Agreement, the
Parent may pay, compromise or defend such Asserted Liability.

                                       62
<PAGE>

Notwithstanding the foregoing, neither the Shareholder nor the Parent may settle
or compromise any Asserted Liability over the objection of the other; provided,
however, consent to settlement or compromise shall not be unreasonably withheld.
In any event, the Parent and the Shareholder may participate, at their own
expense, in the defense of such Asserted Liability. If the Shareholder chooses
to defend any Asserted Liability, the Parent shall make available to the
Shareholder any books, records or other documents within its control that are
necessary or appropriate for such defense.

          (c) The Shareholder shall not be obligated to pay any amounts for
indemnification under this Section 7.4 until the aggregate amounts for
indemnification under Section 7.4 equals U.S.$300,000 (the "Basket Amount"),
                                                            -------------
whereupon the Shareholder shall be obligated to pay in full all such amounts for
such indemnification, in excess of the Basket Amount.

          (d) The Company and the Shareholder shall discharge the entirety of
their indemnity obligations under this Article VII through one of the following
three means:

              (i)  on or prior to the Closing, the Company shall purchase, from
an insurance company or companies reasonably satisfactory to the Parent,
representation and warranty insurance providing at least $20 million of coverage
with a deductible of no greater than the Basket Amount; or

              (ii) on or prior to the Closing, the Shareholder shall cause a
major international bank to issue a letter of credit to the Parent, in a form
and on terms reasonably satisfactory to the Parent, in an amount equal to $20
million and backing the indemnification obligations under this Article VII,
which letter of credit is secured by up to 20% of the Merger Consideration
deposited pursuant to the proviso in the second sentence of Section 2.2(b);or

              (iii) on or prior to the Closing, the Shareholder shall use the
Merger Consideration deposited pursuant to the proviso in the second sentence of
Section 2.2(b) to secure the indemnification obligation under this Article 7 in
another manner reasonably satisfactory to the Parent and consistent with the
requirements of German Law.

          In the event the Shareholder or the Company determine prior to July 1,
2000 that alternative (i) will not be available, the Company and Parent will
amend this Agreement so as to result in an additional 8,712 Parent Shares to be
issued as Merger consideration to the shareholders of the Company.

          Section 8.5  Tax Matters.

          Liability for Taxes and Related Matters.  Notwithstanding the
provisions of Section 7.4 of this Agreement:

                                       63
<PAGE>

          (a) Liability for Taxes.  From and after the Closing Date, the
              -------------------
Shareholder shall be liable and indemnify Parent for all Taxes imposed on the
Company or any Company Subsidiary or for which the Company or any Company
Subsidiary may otherwise be liable for any taxable year or period that ends on
or before the Closing Date and, with respect to any taxable year or period
beginning before and ending after the Closing Date, the portion of such taxable
year or period ending on and including the Closing Date, except for Taxes in an
amount equal to the accrued and unpaid Taxes of the Company and the Company
Subsidiaries reflected on the Interim Financials or reflected on the books and
records of the Company since March 31, 2000, in the ordinary course of business
consistent with past practice and relating to operations since March 31, 2000.
The Shareholder shall be entitled to any refund of Taxes of the Company received
for such periods.

          (b) Taxes for Short Taxable Year.  For purposes of Section 7.5(a),
              ----------------------------
whenever it is necessary to determine the liability for Taxes of the Company or
any Company Subsidiary for a portion of a taxable year or period that begins
before and ends after the Closing Date, the determination of the Taxes of the
Company or any Company Subsidiary for the portion of the year or period ending
on, and the portion of the year or period beginning after, the Closing Date
shall be determined by assuming that the Company and the Company Subsidiaries
had a taxable year or period which ended at the close of the Closing Date,
except that exemptions, allowances or deductions that are calculated on an
annual basis, such as the deduction for depreciation, shall be apportioned on a
time basis.

          (c) Adjustment to Purchase Price.  Any payment by Parent or the
              ----------------------------
Shareholder under this Section 7.5 will be an adjustment to the purchase price.

          (d) Tax Returns.  The Shareholder shall prepare and file or cause to
              -----------
be prepared and filed all Tax Returns with respect to the Company and the
Company Subsidiaries which are required to be filed on or before the Closing
Date.  The Shareholder shall pay any Taxes due in respect of such Tax Returns,
except for Taxes in an amount equal to the accrued and unpaid Taxes of the
Company and the Company Subsidiaries reflected on the Interim Financials or
reflected on the books and records of the Company since March 31, 2000, in the
ordinary course of business consistent with past practice and relating to
operations since March 31, 2000.  Parent shall file or cause to be filed all Tax
Returns with respect to the Company and the Company Subsidiaries which are
required to be filed after the Closing Date and shall cause the Company to remit
any Taxes due in respect of such Tax Returns.  The Shareholder shall pay Parent
the Taxes for which the Shareholder is liable pursuant to Section 7.5(a) but
which are payable with Tax Returns to be filed by Parent pursuant to the
previous sentence within 10 days prior to the due date for the filing of such
Tax Returns.

          (e) Contest Provisions.  Parent shall promptly notify Shareholder in
              ------------------
writing upon receipt by Parent or the Company (or any Company Subsidiary) of
notice of any pending or threatened Federal, state, local or foreign

                                       64
<PAGE>

income or franchise tax audits or assessments which may affect the tax
liabilities of the Company or any Company Subsidiary for which the Shareholder
would be required to indemnify Parent pursuant to Section 7.5(a), provided that
failure to comply with this provision shall not affect Parent's right to
indemnification hereunder. The Shareholder shall have the sole right to
represent the Company's interests in any tax audit or administrative or court
proceeding relating to taxable periods ending on or before the Closing Date, and
to employ counsel of their choice at their expense. Notwithstanding the
foregoing, the Shareholder shall not be entitled to settle, either
administratively or after the commencement of litigation, any claim for Taxes
which would adversely affect the liability for Taxes of Parent or the Company
(or any Company Subsidiary) for any period after the Closing Date to any extent
(including the imposition of income tax deficiencies, the reduction of asset
basis or cost adjustments, the lengthening of any amortization or depreciation
periods, the denial of amortization or depreciation deductions, or the reduction
of loss or credit carryforwards) without the prior written consent of Parent.
Such consent shall not be unreasonably withheld, and shall not be necessary to
the extent that the Shareholder has indemnified Parent against the effects of
any such settlement.

          The Shareholder shall be entitled to participate at its expense in the
defense of any claim for Taxes for a year or period ending after the Closing
Date which may be the subject of indemnification by the Shareholder pursuant to
Section 7.5(a) and, with the written consent of Parent, and at its sole expense,
may assume the entire defense of such tax claim.  Neither Parent nor the Company
may agree to settle any tax claim for the portion of the year or period ending
on the Closing Date which may be the subject of indemnification by the
Shareholder under Section 7.5(a) without the prior written consent of the
Shareholder, which consent shall not be unreasonably withheld.

               (f) Any tax sharing agreement or arrangement, whether or not
written, that may have been entered into by the Shareholder and the Company or
any Company Subsidiary shall be terminated as of the Closing Date, and no
payments which are owed by or to the Company or any Company Subsidiary pursuant
thereto shall be made thereunder.

               (g) Assistance and Cooperation.  After the Closing Date, each of
                   --------------------------
the Shareholder and Parent shall:

                   (i)  assist (and cause their respective affiliates to assist)
the other parties in preparing any Tax Returns or reports which such other
parties are responsible for preparing and filing in accordance with Section 7.5;

                   (ii) cooperate fully in preparing for any audits of, or
disputes with taxing authorities regarding, any Tax Returns of the Company or
any Company Subsidiary;

                                       65
<PAGE>

                (iii) make available to the other party or parties and to any
taxing authority as reasonably requested all information, records and documents
relating to Taxes of the Company or any Company Subsidiary;

                (iv) provide timely notice to the other party or parties in
writing of any pending or threatened tax audits or assessments of the Company or
any Company Subsidiary for taxable periods for which the other party or parties
may have a liability under this Section 7.5; and

                (v)  furnish the other party or parties with copies of all
correspondence received from any taxing authority in connection with any tax
audit or information request with respect to any such taxable period of the
Company or any Company Subsidiary.

          (h) Section 1445.  On or prior to the Closing Date, the Company shall
              ------------
deliver a true and accurate certification satisfying the requirements of Section
1.1445-2(c)(3) of the Treasury Regulations.  In compliance with Section 1.897-
2(h)(2) and Section 1.1445-2(c)(3) of the Treasury Regulations, notification
that such certification has been given shall be made to the IRS.

          (i) Survival of Obligations.  The obligations of the parties set forth
              -----------------------
in this Section 7.5 shall be unconditional and absolute and shall remain in
effect during the applicable statute of limitation as to time and any liability
or the Shareholder under this section shall be subject to Section 7.4(d).
