If,  for  any  period,  the  Company  has  any  subsidiary  whose  accounts  are
consolidated  with those of the  Company,  then in  respect  of such  period the

consolidated subsidiaries.


                                      -3-



            3.2  Inspection.  Without  prejudice  to the rights of the  Investor
under  Statutory  Law, the Company shall permit the Investor,  at the Investor's
expense,  to visit and inspect the  Company's  properties;  examine its books of
account and records; and discuss the Company's affairs,  finances,  and accounts
with its officers,  directors,  Key Employee and independent  public  accountant
during normal  business  hours of the Company as may be reasonably  requested by
the  Investor;  provided,  however,  that the  Company  shall  not be  obligated
pursuant  to this  Section  3.2 to  provide  access to any  information  that it
reasonably  considers to be a trade secret or confidential  information  (unless
covered by an enforceable  confidentiality  agreement, in form acceptable to the
Company) or the disclosure of which would adversely  affect the  attorney-client
privilege between the Company and its counsel.

            3.3 Further  Information.  The Company  shall  provide the  Investor
prompt written notice of material events and communications (oral or in writing)
with and from  any  Person  interested  in  acquiring  the  Company  or  forming
strategic relationships.

            3.4   Confidentiality.   The  Investor  agrees  that  it  will  keep
confidential and will not disclose,  divulge, or use for any purpose (other than
to monitor its investment in the Company) any confidential  information obtained
from  the  Company  pursuant  to  the  terms  of  this  Agreement,  unless  such
confidential  information (a) is known or becomes known to the public in general
(other than as a result of a breach of this Section 3.4 by the Investor), (b) is
or has been independently  developed or conceived by the Investor without use of
the  Company's  confidential  information,  or (c) is or has been made  known or
disclosed to the Investor by a third party without a breach of any obligation of
confidentiality  such third party may have to the  Company;  provided,  however,
that the Investor may disclose  confidential  information  (i) to its attorneys,
accountants,  consultants,  and other  professionals  to the extent necessary to
obtain their  services in  connection  with  monitoring  its  investment  in the
Company;  (ii) to any prospective  purchaser of any Registrable  Securities from
the Investor, if such prospective purchaser agrees to be bound by the provisions
of this Section 3.4; (iii) to any Affiliate,  partner, member,  stockholder,  or
wholly owned  subsidiary  of such  Investor in the ordinary  course of business,
provided  that the  Investor  informs  such  Person  that  such  information  is
confidential  and directs  such Person to maintain the  confidentiality  of such
information;  or (iv) as may  otherwise  be required by law,  provided  that the
Investor  promptly  notifies the Company of such disclosure and takes reasonable
steps to  minimize  the  extent of any such  required  disclosure.  The  Company
acknowledges  that  certain  officers  of the  Investor  are in the  business of
venture  capital  investing and therefore  review the business plans and related
proprietary information of many enterprises, including enterprises that may have
products or services  that  compete  directly  or  indirectly  with those of the
Company.  Nothing in this  Agreement  shall preclude or in any way restrict such
officers of the Investor  from  investing  or  participating  in any  particular
enterprise,  regardless of whether such enterprise has products or services that
compete with those of the Company.

      4. Rights to Future Stock Issuances.

            4.1 Right of First  Offer.  Subject to the terms and  conditions  of
this Section 4.1 and  applicable  securities  laws,  if the Company  proposes to
offer or sell  any New  Securities,  the  Company  shall  first  offer  such New
Securities  to the  Investor.  The Investor  shall be entitled to apportion  the
right of first offer  hereby  granted to it among itself and its  Affiliates  in
such proportions as it deems appropriate.

               (a) The Company  shall give  notice  (the "Offer  Notice") to the
Investor, stating (i) its bona fide intention to offer such New Securities, (ii)
the number of such New Securities to be offered,  and (iii) the price and terms,
if any, upon which it proposes to offer such New Securities.


                                      -4-



               (b) By  notification to the Company within thirty (30) days after
the Offer Notice is given,  the Investor,  through itself and/or its Affiliates,
may  elect to  purchase  or  otherwise  acquire,  at the  price and on the terms
specified in the Offer Notice,  up to that portion of such New Securities  which
equals  the  proportion  that the  Common  Stock  issued  and held and any other
Derivative Securities then held, by the Investor bears to the total Common Stock
of the Company then  outstanding  (assuming full  conversion and exercise of all
Derivative Securities).  The closing of any sale pursuant to this Section 4.1(b)
shall occur within sixty (60) days of the date that the Offer Notice is given.

               (c) If all New Securities referred to in the Offer Notice are not
elected to be purchased or acquired as provided in Section  4.1(b),  the Company
may,  during the ninety (90) day period  following the  expiration of the period
provided in Section 4.1(b), offer and sell the remaining unsubscribed portion of
such New  Securities to any Person or Persons at a price not less than, and upon
terms no more  favorable  to the  offeree  than,  those  specified  in the Offer
Notice.  If the Company does not enter into an agreement for the sale of the New
Securities  within such period,  or if such agreement is not consummated  within
thirty (30) days of the execution thereof, the right provided hereunder shall be
deemed to be revived and such New  Securities  shall not be offered unless first
reoffered to the Investor in accordance with this Section 4.1.

               (d) The  right of first  offer in this  Section  4.1 shall not be
applicable to Permitted Issuances.

            4.2  Termination.  The  covenants  set  forth in  Section  4.1 shall
terminate  and  be  of  no  further  force  or  effect  immediately  before  the
consummation of the IPO.

      5. Right of Co-Sale.

               (a)  Exercise of Right.  Subject to the terms and  conditions  of
this Section 5 and applicable  securities  laws, if any Founder  intends to sell
any capital stock  (including  any Common Stock) to any third party (a "Proposed
Founder  Transfer"),  such Founder must deliver  written  notice (the  "Proposed
Transfer  Notice") to the Investor not later than  forty-five (45) days prior to
the  consummation  of such Proposed  Founder  Transfer;  such Proposed  Transfer
Notice shall contain the material terms and conditions (including price and form
of  consideration)  of the  Proposed  Founder  Transfer  and the identity of the
Prospective Transferee.  The Investor shall have the right to, and may elect to,
participate on a pro rata basis in the Proposed  Founder Transfer (the "Right of
Co-Sale") as set forth in Section 5(b) below and otherwise on the same terms and
conditions  specified in the Proposed  Transfer  Notice  (provided  that if such
Founder is selling capital stock other than Common Stock, the price set forth in
the Proposed Transfer Notice shall be appropriately adjusted into Common Stock).
If the Investor desires to exercise its Right of Co-Sale, the Investor must give
the selling Founder written notice to that effect within fifteen (15) days after
receipt  of the  Proposed  Transfer  Notice,  and upon  giving  such  notice the
Investor shall be deemed to have effectively  exercised the Right of Co-Sale and
such selling Founder shall not consummate such Proposed Founder Transfer without
the  inclusion  of the shares of Common  Stock of the  Investor  as to which the
Right of Co-Sale has been exercised.


                                      -5-



               (b) Shares Includable. Upon exercise of the Right of Co-Sale, the
Investor  may include in the Proposed  Founder  Transfer all or any part of such
Investor's  Common Stock equal to the product  obtained by  multiplying  (i) the
aggregate  number of shares of Common  Stock owned by the  Investor  immediately
before  consummation of the Proposed  Founder  Transfer by (ii) a fraction,  the
numerator  of which is the number of shares of  capital  stock to be sold in the
Proposed Founder  Transfer,  and the denominator of which is the total number of
shares  of  capital  stock  owned  by  the  Founders  immediately  prior  to the
consummation of the Proposed  Founder  Transfer.  In the event that the Investor
exercises such Right of Co-Sale in accordance  with the terms and conditions set
forth herein, and the Prospective Transferee is unwilling to purchase the shares
described  in the  Proposed  Transfer  Notice plus the number of shares that the
Investor  is entitled  to sell  pursuant to the Right of Co-Sale,  the number of
shares of  capital  stock  that the  selling  Founder  may sell in the  Proposed
Founder Transfer shall be reduced on a pro rata basis.

               (c)  Delivery of  Certificates.  The  Investor  shall  effect its
participation  in the Proposed  Founder  Transfer by  delivering  to the selling
Founder,  no later than fifteen (15) days after the  Investor's  exercise of the
Right of Co-Sale,  a duly executed power of attorney relating to the sale of the
number of shares of Common  Stock  that the  Investor  elects to  include in the
Proposed Founder Transfer.

               (d) Purchase  Agreement.  The parties hereby agree that the terms
and conditions of any sale pursuant to this Section 5 will be  memorialized  in,
and governed by, a written  purchase and sale agreement with customary terms and
provisions for such a transaction and the parties further  covenant and agree to
enter  into such an  agreement  as a  condition  precedent  to any sale or other
transfer pursuant to this Section 5.

               (e) Deliveries.  The shares covered by the power of attorney that
the Investor delivers to the selling Founder pursuant to Section 5(c) above will
be  transferred  to the  Prospective  Transferee  against  payment  therefor  in
consummation of the sale  contemplated by the Proposed Founder Transfer pursuant
to the terms and conditions  specified in the Proposed  Transfer  Notice and the
purchase  and  sale  agreement,  and  the  selling  Founder  shall  concurrently
therewith  remit or direct  payment to the  Investor of that portion of the sale
proceeds to which the  Investor is  entitled by reason of its  participation  in
such sale. If any  Prospective  Transferee or Transferees  refuse(s) to purchase
securities  subject to the Right of Co-Sale  from the  Investor  exercising  its
Right of  Co-Sale  hereunder,  no  Founder  may sell any  capital  stock to such
Prospective Transferee or Transferees unless and until, simultaneously with such
sale, such Founder purchases all securities subject to the Right of Co-Sale from
the Investor on the same terms and conditions  (including the proposed  purchase
price) as set forth in the Proposed Transfer Notice.


                                      -6-



               (f) Additional  Compliance.  If any Proposed  Founder Transfer is
not  consummated  within sixty (60) days after receipt of the Proposed  Transfer
Notice by the Investor,  the Founder proposing the Proposed Founder Transfer may
not sell any capital stock unless they first comply in full with each  provision
of this  Section 5. The  exercise or election  not to exercise  any right by the
Investor  hereunder  shall not adversely  affect its right to participate in any
other purchases or sales of capital stock subject to this Section .

               (g) Violation of Co-Sale Right.  If any Founder  purports to sell
any  capital  stock in  contravention  of the Right of  Co-Sale  (a  "Prohibited
Transfer"),  the Investor  may, in addition to such remedies as may be available
by law,  in equity or  hereunder,  require  such  Founder to  purchase  from the
Investor the number of shares of Common Stock that the Investor  would have been
entitled  to sell to the  Prospective  Transferee  under this  Section 5 had the
Prohibited  Transfer been effected  pursuant to and in compliance with the terms
of Section  5. The sale will be made on the same  terms and  subject to the same
conditions  as would  have  applied  had the  Founder  not  made the  Prohibited
Transfer, except that the sale (including,  without limitation,  the delivery of
the  purchase  price)  must be made within  twenty (20) days after the  Investor
learns of the  Prohibited  Transfer,  as opposed to the timeframe  prescribed in
Section  5(f).  Such Founder  shall also  reimburse the Investor for any and all
reasonable and documented out-of-pocket fees and expenses,  including reasonable
legal fees and  expenses,  incurred  pursuant to the  exercise or the  attempted
exercise of the Investor's rights under Section 5.

      6. Anti-Dilution Protection.

               (a) If at any time or from  time to time  after  the date of this
Agreement,  the Company issues or sells, or is deemed by the express  provisions
of this Section 6 to have issued or sold,  Additional Shares of Common Stock (as
defined in Section 6(d) hereof),  for an Effective  Price (as defined in Section
6(d))  less than the then  applicable  Adjusted  Price Per Share (as  defined in
Section  6(d)),  then in each such  case,  in  consideration  of the  Investor's
payment of the requisite par value of the Common Stock to be issued  pursuant to
this Section 6.1(a), the Company shall issue an additional share of Common Stock
to the  Investor,  as of the  opening of  business  on the date of such issue or
sale, the nominal Euro value of such additional  share to be calculated by using
the following formula:

                           D = ((A * B)/C)  - B

                  For purpose of the foregoing formula:

                  A =    Adjusted Price Per Share.
                  B      Nominal  amount of the  Common  Stock of the  Company
                         issued  to  the  Investor   pursuant  to  the  Purchase
                         Agreement.
                  C =    Effective Price of Additional Shares of Common Stock.
                  D =    Nominal value of the  additional  share of Common Stock
                         to be issued to the  Investor.

      If D is not divisible by 50, the nominal value of the additional  share of
Common Stock to be issued to the  Investor  shall be the value that results from
rounding D to the next higher value divisible by 50.


                                      -7-



               (b) For the purpose of the adjustment required under this Section
6, the consideration received by the Company for any issue or sale of securities
shall (i) to the extent it  consists  of cash,  be computed at the net amount of
cash  received by the Company  after  deduction of any  underwriting  or similar
commissions,  compensation  or  concessions  paid or allowed  by the  Company in
connection with such issue or sale but without deduction of any expenses payable
by the Company,  (ii) to the extent it consists of property  other than cash, be
computed at the fair value of that  property as  determined in good faith by the
managing  directors of the  Company,  and (iii) if  Additional  Shares of Common
Stock,  Convertible Securities (as defined in Section 6(c)) or rights or options
to purchase either Additional  Shares of Common Stock or Convertible  Securities
are issued or sold  together  with other stock or  securities or other assets of
the Company for a consideration which covers both, be computed as the portion of
the consideration so received that may be reasonably determined in good faith by
the  managing  directors to be  allocable  to such  Additional  Shares of Common
Stock, Convertible Securities or rights or options.

               (c) For the purpose of the adjustment required under this Section
6, if the  Company  issues or sells (i)  stock or other  securities  convertible
into,  Additional  Shares of Common Stock (such  convertible stock or securities
being herein referred to as "Convertible  Securities") or (ii) rights or options
for the purchase of Additional Shares of Common Stock or Convertible  Securities
and if the  Effective  Price of such  Additional  Shares of Common Stock is less
than the Price Per Share,  in each case the Company  shall not be deemed to have
issued the Additional Shares of Common Stock at the time of the issuance of such
rights or options or  Convertible  Securities.  The  adjustment  to the Adjusted
Price Per Share shall occur upon the  issuance of shares of Common  Stock issued
due to the sale or upon the  conversion or exercise of such rights or options or
Convertible Securities.

               (d) For  purposes of this  Section 6, the  following  terms shall
have the meaning assigned below:


                                    (i)  "Additional  Shares  of  Common  Stock"
                  shall mean all shares of Common Stock issued by the Company or
                  deemed to be issued  pursuant  to this  Section  6, other than
                  Permitted Issuances.

                                    (ii)  "Adjusted  Price Per Share" shall mean
                  initially,  (euro)50.70  for each Euro nominal value of shares
                  of Common Stock of the Company  (subject to adjustment for any
                  splits,  reserve  splits,  combinations or similar events) and

or partnerships  wholly owned or benefiting  such parties) of such  Shareholder,
provided, that such transfer shall be contingent upon the transferee providing a
written  instrument  to the Company  notifying  the Company of such transfer and
such  transferee  becoming a party to this Agreement by executing and delivering
an  additional  counterpart  signature  page to this  Agreement  to the Company.
Notwithstanding the foregoing,  up to five percent (5%) of the shares of capital
stock held by Andy Roesch as of the date hereof, may by transferred  without the
Investor's prior written consent to a third party, provided, such third party is

providing  a written  instrument  to the Company  notifying  the Company of such
transfer and such transferee becoming a party to this Agreement by executing and
delivering an additional  counterpart  signature  page to this  Agreement to the
Company.  Thereafter,  in each  such  case of  permissible  transfer  hereunder,
following the delivery of the required written  instrument and signature page to
the Company,  such transferee  shall be deemed a "Shareholder"  for all purposes
hereunder.

            8.2 Shareholder Action. The Shareholders shall duly and promptly and
in the form required by law, resolve any shareholder resolution,  enter into any
agreement,  execute any  transaction and perform any other action (whether legal
or factual ) that is or may become  necessary  in order to enable the Company to
fulfill  its  obligations  and  covenants  under this  Agreement,  the  Purchase
Agreement  or any other part of the  Transaction  Agreements  (as defined in the
Purchase  Agreement),  including,  without  limitation,  the issuance of capital
stock  upon any  conversion  of the Long Term Note (as  defined in the Long Term
Note). The obligation pursuant to the immediately  preceding sentence to perform
any action  required in  connection  with any  conversion  of the Long Term Note
includes,  without limitation,  the shareholders' resolution for the increase of
the Company's  share capital as required  under the terms of the Long Term Note,
the admission of the Conversion Holder as sole subscriber to the new share under
such capital  increase,  the waiver of any shareholder other than the Conversion
holder  to  participate  in  such  capital  increase,  the  cooperation  in  the
subscription  by the Conversion  Holder of the new share,  and the filing of the
Capital Increase to the Commercial Register.

non-exclusive  jurisdiction  of the  courts  of  competent  jurisdiction  of the
Republic of Germany with respect to any action brought by the Conversion  Holder
(as  defined in the Long Term Note) to enforce  its rights to convert  such Long
Term Note.

            8.3   Administrative   Board.   The  parties   shall   establish  an
Administrative  Board  as  provided  by  Sec.  7 of  the  Restated  Articles  of
Association,  by executing a shareholders'  resolution substantially in the form
attached to this  Agreement as Exhibit  8.3.  The Investor  will always have the
right to nominate at least 50% of the members of this Administrative  Board. One
member appointed by the Investor shall be appointed  chairman.  The Shareholders
shall  at  any  time  implement   such   nominations  by  passing  the  required
shareholders'  resolutions and shall abstain from any resolutions and actions in
contravention thereof.

            9.1 Successors and Assigns. The Investor hereby agrees that it shall
not, and may not,  assign any of its rights and  obligations  hereunder,  unless

will be valid, legal, and enforceable to the maximum extent permitted by law.

right,  power, or remedy  accruing to any party under this  Agreement,  upon any
breach or default of any other party under this Agreement, shall impair any such
right,  power, or remedy of such nonbreaching or nondefaulting  party, nor shall
it be construed to be a waiver of or acquiescence to any such breach or default,

default theretofore or thereafter  occurring.  All remedies,  whether under this
Agreement or by law or otherwise  afforded to any party, shall be cumulative and
not alternative.


                                      -12-
