      THIS JOINT VENTURE AGREEMENT (this "AGREEMENT"), effective as of April 10,
2005, is made by and between BRIDGETECH HOLDINGS INTERNATIONAL, INC., a Delaware
corporation ("BRIDGETECH"), and AMCARE LABS INTERNATIONAL, INC., a Delaware

                     Thirty Thousand Dollars ($30,000) (the "INITIAL

                  with US generally accepted accounting principles. Each Party
                  will be entitled to require Newco1 and Newco2 to provide to it
                  all such information as may be required for the purposes of
                  the preparation of their respective accounts in accordance
                  with such generally accepted accounting principles and the
                  requirements of the law applicable in their respective
                  jurisdictions. Each Party will be entitled to receive all such
                  information relating to the affairs of Newco1 and Newco2 as
                  may be requested at any time and from time to time by any
                  Party. Newco1 and Newco2 will provide to the Parties regular
                  and periodic reports on the business, operations and financial
                  and other affairs of Newco1 and Newco2.

            (f)   Newco1 and Newco2 shall each keep their funds separate from
                  those of any other person and shall maintain its own

            (g)   Any transactions or agreements between Newco1 or Newco2 and
                  any of their affiliates, including BRIDGETECH and AMCARE, will
                  be entered into on an arms'-length basis upon terms that are
                  (i) no less favorable to Newco1 or Newco2, respectively, than
                  would apply in a transaction with a person that is not an
                  affiliate, or (ii) subject to Section 3.3(e)(vii), fully

                  Newco2 by June 15, 2005.

      3.6   Compliance with Laws Regarding Payments. None of Newco1, Newco2 or
            any of their officers and directors, nor anyone for whose acts or
            defaults they may be vicariously liable or anyone acting on behalf
            of any of them, including any Party hereto, shall make any payments
            in violation of applicable law in connection with or in any way
            relating to or affecting this Agreement or the business to be
            carried on by Newco1 or Newco2, nor shall such persons make any
            payments in violation of any applicable code of conduct of either
            BRIDGETECH or AMCARE, provided that such code of conduct is
            commercially reasonable. The Parties acknowledge that the laws of
            the United States of America, including the Foreign Corrupt
            Practices Act, prohibit any direct or indirect payment of money or
            anything of value to any governmental official, international
            organization, political Party or candidate for political office for
            the purpose of obtaining or retaining business. The Parties
            represent and warrant to each other that in the performance of their
            obligations under this Agreement or otherwise in connection with
            this Agreement they have not made and agree that they will not make
            any such prohibited payment.

                  Agreement, BRIDGETECH and AMCARE, will not, except in
                  situations to which the exclusivity provisions in Section 4.1
                  above do not apply because of applicable law, rules or
                  regulations:

                  (i)   establish or operate, directly or indirectly, a
                        pathology lab or clinical research organization in the
                        Territory, other than through Newco1 and Newco2;

                  (ii)  own any interest in, directly or indirectly, or
                        otherwise participate in, directly or indirectly, any
                        entity other than Newco1 or Newco2 that is involved in
                        any aspect of either a MTF or clinical research
                        organization in the Territory, or

                  (iii) compete, directly or indirectly, in the Territory in any
                        other activity undertaken by Newco1 or Newco2 in the
                        Territory.

      4.3 Definitions. For purposes of this Section 4, the term "AFFILIATE"
means, for any person, any stockholder, partner, member or other equity owner of
such person or any other person directly or indirectly controlling, controlled
by or under common control with such person.

5.    Term and Termination.

      5.1   Term. Subject to Sections 5.3, the Project will have an initial term
            of 10 years (the "PROJECT TERM"), at the end of which time the
            Project Term may be extended for additional 1 year terms (all such
            renewal terms shall be considered part of the "Project Term"),
            unless either Party notifies the other no later than 60 days before
            the end of the Project Term that it does not wish to extend the
            Project Term.

      5.2   End of Project Term. Unless the Project Term is terminated
            previously pursuant to Section 5.3, at the end of the Project Term,
            the Parties will enter into negotiations with each other for the
            purpose of determining a price at which either Party would purchase
            the other Party's shares in Newco1 and/or Newco2. Unless otherwise
            agreed the purchase price will be payable in cash at closing. If the
            Parties are unable to agree upon a price for either or both of
            Newco1 and Newco2, then the Parties will jointly retain, or cause
            Newco1 and Newco2, as applicable, to retain, an internationally
            recognized investment bank or other financial advisor to solicit a
            purchaser or purchasers for all the outstanding shares of Newco1
            and/or Newco2, together or separately, each as a going concern with
            all outstanding contracts, including those to which BRIDGETECH,
            AMCARE or their affiliates are a Party, other than any outstanding
            indebtedness of Newco1 and Newco2 to the Parties which will be
            repaid upon sale. In the event that no bids are received within 180
            days after the end of the Project Term for Newco1 or Newco2,
            respectively, or if for any reason a proposed sale to a successful
            bidder does not occur within 180 days after the end of the Project
            Term, then the Parties will require that Newco1 and Newco2
            (whichever receives no bids or remains unsold at the end of the
            prescribed periods) be wound up in accordance with applicable law.
            From the end of the Project Term until such time as Newco1 and
            Newco2 are sold or wound up as provided above, this Agreement and
            the Related Agreements shall remain in effect, and Newco1 and Newco2
            shall be operated in the ordinary course of business.

                  procedure, formula, or improvement that is commercially

      8.2   Nondisclosure. Each Party shall treat as confidential, and the
            Parties shall together cause Newco1 and Newco2 to treat as
            confidential, all Confidential Information of the other Party, shall
            not use such Confidential Information except as set forth herein,
            and shall use reasonable efforts not to disclose such Confidential
            Information to any third party. Without limiting the foregoing, each
            of the Parties shall use at least the same degree of care which it
            uses to prevent the disclosure of its own confidential information
            of like importance to prevent the disclosure of Confidential
            Information disclosed to it by the other Party under this Agreement.
            Neither BRIDGETECH nor AMCARE shall be entitled to access, use or
            disclose any Confidential Information of the other Party solely by
            virtue of the provision of such Confidential Information by the
            Disclosing Party to Newco1 or Newco2.

      8.3   Exceptions. Notwithstanding the above, neither Party shall have
            liability to the other with regard to any Confidential Information
            of the other which the Restricted Party can prove: (i) was in the
            public domain at the time it was disclosed or has entered the public
            domain through no fault of the Restricted Party; (ii) was known to
            the Restricted Party, without restriction, at the time of disclosure
            (iii) is disclosed with the prior written approval of the Disclosing
            Party; (iv) was independently developed by the Restricted Party
            without any use of the Confidential Information of the other Party,
            (v) becomes known to the Restricted Party, without restriction, from
            a source other than the Disclosing Party without breach of this
            Agreement by the Restricted Party and otherwise not in violation of
            the Disclosing Party's rights; (vi) is disclosed generally to third
            parties by the Disclosing Party without restrictions similar to
            those contained in this Agreement; or (vii) is disclosed pursuant to
            the order or requirement of a court, administrative agency, or other
            governmental body; provided, however, that the Restricted Party
            shall provide prompt notice thereof to the Disclosing Party to
            enable the Disclosing Party to seek a protective order or otherwise
            prevent or restrict such disclosure.

      8.4   Return of Confidential Information. Upon expiration or termination
            of the Project, each Party shall return or destroy, and together
            shall cause Newco1 and/or Newco2, as applicable, to return or
            destroy, all Confidential Information received from the other Party.

      8.5   Confidentiality of Agreement. Each Party shall be entitled to
            disclose the existence of this Agreement, but agrees that the terms
            and conditions of this Agreement shall be treated as Confidential
            Information and shall not be disclosed to any third party; provided,
            however, that each Party may disclose the terms and conditions of
            this Agreement: (i) as required by any court or other governmental
            body; (ii) as otherwise required by law; (iii) to legal counsel of
            the Parties; (iv) in confidence, to accountants, banks, and
            financing sources and their advisors; (v) in connection with the
            enforcement of this Agreement or rights under this Agreement; (vi)
            in confidence, in connection with an actual or proposed merger,
            acquisition, or similar transaction or (vii) in accordance with
            Section 9, below.

      8.6   Intellectual Property. Each of BRIDGETECH and AMCARE acknowledge
            that, during the course of the Project, BRIDGETECH or AMCARE may
            license or otherwise permit Newco1 or Newco2 to use certain patents,
            trademarks, trade names, service marks, domain names, copyrights,
            designs, processes, formulae, methods, schematics, technology,
            invention, trade secrets, know-how, computer software programs or
            applications and tangible or intangible proprietary information or
            material (collectively, "INTELLECTUAL PROPERTY") owned or licensed
            by such Party (the "OWNER") in order to permit Newco1 and Newco2 to
            perform their obligations under the Project Documents or otherwise.
            The Parties acknowledge and agree that, and the Parties shall cause
            Newco1

                                       16

<PAGE>

            and Newco2 to acknowledge and agree that, except to the extent that
            (i) such Intellectual Property is expressly and specifically
            contributed in writing by the Owner thereof as part of an equity
            contribution to Newco1 or Newco2 to which the other Party consents
            in writing, or (ii) such Intellectual Property is expressly and
            specifically sold to Newco1 or Newco2 by the Owner thereof in
            accordance with the provisions of this Agreement, none of Newco1,
            Newco2 or the non-Owner Party shall acquire any rights, express or
            implied, in the Intellectual Property other than those specified in
            Project Document pursuant to which such license or right to use was
            granted. For the avoidance of doubt, in no event shall Newco1 or
            Newco2 license or otherwise permit the non-Owner Party or any third
            party to use any such Intellectual Property to which it may be given
            access pursuant to the terms of the Project Documents without the
            prior written consent of the Owner.

      8.7   Remedies. Any breach of the restrictions contained in this Section 8
            is a breach of this Agreement which may cause irreparable harm to
            the non-breaching Party. Any such breach shall entitle the
            non-breaching Party to injunctive relief in addition to all legal
            remedies.

9.    Press Release and Announcements. BRIDGETECH and AMCARE agree that no
      public release or announcement concerning the transactions contemplated
      hereby shall be issued or made by or on behalf of any Party without the
      prior consent of the other Party, except that either Party may, after
      consultation with counsel, make announcements that such Party reasonably
      may determine are necessary to comply with applicable law. AMCARE
      acknowledges and agrees that BRIDGETECH may be required to announce the
      terms of this Agreement and make publicly available this Agreement and
      that no breach of this Section 9 shall be deemed to result therefrom.
      Notwithstanding the foregoing, BRIDGETECH and AMCARE shall cooperate to
      prepare a joint press release to be issued in connection with the Closing.

10.   Indemnification.

      10.1  Indemnification. Each Party (the "Indemnifying Party") will defend,
            indemnify, and hold the other Party and its Affiliates, officers and
            directors, shareholders, and each of its and their successors and
            permitted assigns (the "Indemnified Parties"), harmless from and
            against any and all liabilities, judgments, losses, actual damages,
            costs, and expenses (including without limitation reasonable
            attorneys' and experts' fees) which any or all of them may hereafter
            incur themselves or pay out to another by reason of any claim, suit,
            or proceeding brought by a third party, at law or in equity, that
            arises out of or relates to (i) a material breach of any
            representation, warranty, covenant, obligation or other provision of
            this Agreement by the Indemnifying Party or (ii) any other Event of
            Default, except to the extent caused by the gross negligence or
            willful misconduct of an Indemnified Party.

      10.2  Indemnification Procedures. To the extent that the indemnification
            described in Section 10.1 above relates to a claim, suit or
            proceeding by a third party, the Indemnifying Party must keep the
            Indemnified Parties fully informed regarding the status or progress
            of any claim, suit, settlement or proceeding related hereto. The
            defense of the Indemnified Parties shall be provided by attorneys
            selected and retained by the Indemnifying Party at its sole cost and
            expense, which attorneys shall be subject to the prior written
            approval of the Indemnified Parties (not to be unreasonably
            withheld, conditioned or delayed). The Indemnified Parties shall
            have the right to participate, and be represented by attorneys or
            other representatives of their choosing (at their sole cost and
            expense) in the defense of such claim, suit or proceeding and all
            settlement negotiations relative thereto. The Indemnifying Party
            shall have the right to determine all matters in connection with the
            claim, suit or proceeding including, without limitation, in
            connection with negotiations relating to the settlement thereof,
            provided, however, that any settlement of such claim,

                                       17

<PAGE>

            suit or proceeding shall require the Indemnified Parties to be
            released of all liability with respect thereto. In the event that
            the Indemnifying Party fails or refuses to indemnify any Party with
            respect to any claim or matter indemnified under this Section 10
            after written notice and a reasonable opportunity to do so, said
            Indemnified Party shall have the right to defend such claim or
            matter at the sole cost and expense of the Indemnifying Party,
            through attorneys selected by the Indemnified Party in its sole
            discretion. The indemnities set forth in this Section 10 shall
            survive expiration or earlier termination of this Agreement.

      10.3  Exclusion of Consequential Damages. NOTWITHSTANDING ANYTHING TO THE
            CONTRARY CONTAINED IN THIS AGREEMENT, NEITHER PARTY SHALL, UNDER ANY
            CIRCUMSTANCES, BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS,
            CONSEQUENTIAL, INCIDENTAL, SPECIAL, PUNITIVE, OR INDIRECT DAMAGES
            ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS
            CONTEMPLATED HEREUNDER, EVEN IF THE PARTY HAS BEEN APPRISED OF THE
            LIKELIHOOD OF SUCH DAMAGES.

11.   Dispute Resolution Procedure.

      11.1  General. The Parties desire to resolve disputes arising out of this
            Agreement without litigation. Accordingly, except as otherwise
            provided in this Section 11, all disputes, controversies, or claims
            arising out of or relating to this Agreement or an Event of Default
            (as defined in this Agreement), or the breach, termination, or
            validity of this Agreement (a "Dispute"), shall be resolved in
            accordance with this Section 11.

      11.2  Discussions to Resolve Dispute. At the written request of either
            Party identifying a Dispute, the Parties to the Dispute shall
            appoint knowledgeable, responsible representatives to meet and
            negotiate in good faith to attempt to resolve the Dispute. The
            Parties intend that these negotiations be conducted by non-lawyer,
            business representatives, including at least one senior executive of
            each Party to the dispute. The location, format, frequency,
            duration, and conclusion of these discussions shall be left to the
            discretion of the representatives. Discussion and correspondence
            among the representatives for purposes of these negotiations shall
            be treated as confidential information developed for purposes of
            settlement, exempt from discovery and production, which shall not be
            admissible in any arbitration or other proceeding. Documents
            identified in or provided with such communications, but which were
            not prepared for purposes of the negotiations, are not so exempted.

      11.3  Arbitration. Any Dispute not resolved by negotiation pursuant to
            Section 11.2 within thirty (30) days of the written request for
            negotiation, shall be finally resolved, at the initiative of either
            Party, by binding arbitration in accordance with this Section 11 and
            the International Arbitration Rules of the American Arbitration
            Association (the "AAA Rules").

      11.4  Venue. Any arbitration under this Section 11 shall be conducted
            pursuant to the Federal Arbitration Act, 9 U.S.C. Section 1 et seq.,
            in New York, New York or such other location as may be agreed by the
            Parties.

      11.5  Selection of Arbitrators. There shall be one arbitrator, who shall
            have at least five (5) years' experience in or with the health care
            industry. If the Parties are unable to agree on the selection of the
            arbitrator within twenty-one (21) days of the notice of arbitration,
            the arbitrator shall be chosen in accordance with the AAA Rules.

                                       18

<PAGE>

      11.6  Waiver of Special, Consequential, and Punitive Damages. The award of
            the arbitrator may not include any element of special,
            consequential, or punitive damages, and the right to claim such
            damages is hereby expressly waived by each Party.

      11.7  Provisional Relief. Either Party may seek from any court of
            competent jurisdiction any provisional relief that may be required
            to protect its rights or rights created pursuant to this Agreement,
            without prejudice to its agreement to arbitrate Disputes under this
            Section 11.

      11.8  Jurisdiction. The Parties hereby consent to the non-exclusive
            jurisdiction of the Courts of the State of New York for purposes of
            any application for provisional relief under Section 11.7 or to
            enforce any provision of this Section 11, or any arbitration award
            hereunder, but both Parties remain free to seek similar relief from
            any court in any other jurisdiction in which such relief may be
            needed.

      11.9  Award; Fees and Expenses. The award of the arbitrator may be entered
            in any court of competent jurisdiction. The fees and costs of the
            Parties to any dispute resolved by arbitration under this Section
            11, including without limitation the arbitrator's fees and all
            attorneys' fees and expenses, shall be allocated in the award.

12.   Miscellaneous.

      12.1  Binding Effect. This Agreement shall be binding on and inure to the
            benefit of the Parties and their respective successors and permitted
            assigns.

      12.2  Assignment. This Agreement shall not be assigned by either Party
            without the prior written consent of the other Party, not to be
            unreasonably delayed or withheld, and any purported such assignment
            without such consent shall be void. For purposes of this Section
            12.2, a merger involving a Party shall be deemed to result in an
            assignment of this Agreement to the surviving entity in the merger,
            regardless of whether the Party is the surviving entity or merging
            entity to such merger.

            (a)   Each notice, communication and delivery under this Agreement

            other than those as to which it is contrary, invalid or

            applicable law and regulation.

      12.5  Amendment; No Waiver. This Agreement shall only be amended upon the
            written agreement of each Party hereto. No waiver by either Party of
            any one or more defaults by the other Party in the performance of
            any of the provisions of this Agreement shall operate or be
            construed as a waiver of any other default or defaults whether of a
            like kind or different nature. No delay by either Party in the
            enforcement of any of its rights under this Agreement shall be
            deemed to be a waiver of such rights.

            by this Agreement, nothing in this Agreement shall create or be
            deemed to create a partnership or joint venture between the Parties

            whatsoever upon any person other than BRIDGETECH, AMCARE, Newco1 and
            Newco2 and shall not create, or be interpreted as creating, any
            standard of care, duty or liability to any person not a Party

      12.9  Governing Law. The Project Documents will be governed by the laws of

      12.10 Certain Rules of Construction. The following rules of construction
            will apply throughout this Agreement and any Project Document.

            (a)   Headings. Any headings used in this Agreement or in any other
                  Project Documents are for the purpose of convenience only and
                  shall not affect the meaning or interpretation of the
                  agreement or document in question.

            (b)   Words of Inclusion. The word "including" will not be construed
                  to be a term of limitation, so that references to "included"
                  matters or items will be regarded as illustrative and will not
                  be interpreted as a limitation on, or an exclusive listing of,
                  the matters or items referred to.

            (c)   Singular and Plural Forms; Genders. Whenever the context so
                  requires, the singular includes the plural and the plural
                  includes the singular, and the gender of any pronoun includes
                  the other genders.

      12.11 Counterparts. This Agreement may be executed by each Party upon a
            separate copy, and in several counterparts, each of which will be
            deemed to be an original and all of which, taken together, shall
            constitute one and the same instrument.

                            (Signature page follows.)

<PAGE>

                         ARTICLE II. STOCK CERTIFICATES

      2.1 Stock Certificates. Stock certificates shall be issued in consecutive
order and shall be numbered in the order in which they are issued. They shall be
signed by the President or the Secretary (any of which signatures may be a
facsimile), and the seal of the Corporation or a facsimile of it shall be
affixed to the stock certificate.

      2.2 List of Stockholders. The Corporation shall maintain an alphabetical
record of the names and addresses of its Stockholders and the number of shares
of stock held by each, which shall be maintained and made available in
accordance with the DGCL.

      2.3 Transfers of Stock. Transfers of stock of the Corporation shall be
made in the stock records of the Corporation upon surrender of the certificate
for such stock signed by the person in whose name the certificate is registered
or on his behalf by a person legally authorized to so sign (or accompanied by a

subject to any other restrictions placed on the transfer of such stock.

      2.4 Lost Certificates. The Corporation may issue a new stock certificate
in place of any certificate or certificates previously issued by the Corporation
and alleged to have been lost or destroyed upon the making of an affidavit of
that fact by the person claiming the certificate to be lost or destroyed and, if
the President in his sole discretion deems it appropriate, the delivery of a
commercial indemnity bond issued by a company approved by him in such sum as he
may direct as indemnity against any claim that may be made against the
Corporation with respect to the certificate alleged to have been lost or
destroyed.

                       ARTICLE III. STOCKHOLDERS' MEETINGS

      3.1 Annual Meetings of Stockholders. The annual meeting of the
Stockholders of the Corporation shall be held within the first four months after
the end of each fiscal year of the Corporation at such time and place, within or
without the State of Delaware, as may from time to time be fixed by the Board or
the President; provided that the failure to hold an annual meeting shall not
work a forfeiture of or otherwise affect valid corporate acts.

      3.2 Special Meetings of Stockholders. Special meetings of the Stockholders
may be called at any time by the Board or the President, or by the Corporation
upon the written request of the holder or holders of at least 15 percent of the
outstanding shares of stock of the Corporation. Special meetings of the
Stockholders shall be held at such time and place, within or without the State
of Delaware, as may be determined by the person or persons calling the meeting.

      3.3 Notice. The Secretary or the officer or persons calling the meeting
shall deliver a written notice of the place, if any, day and time of each
meeting of the Stockholders, not less than ten (10) nor more than sixty (60)
days before the date of the meeting, to each Stockholder of record entitled to
vote at such meeting. Such notice shall be given in any manner permitted by

<PAGE>

the DGCL. If mailed, such notice shall be deemed to be delivered five (5) days
after it is deposited in the United States mail with first class postage thereon
prepaid, addressed to the Stockholder at his address as it appears on the stock
records of the Corporation. The notice of a special meeting of the Stockholders
shall state the purpose or purposes for which the meeting is called. If the
meeting is to be held by means of remote communication pursuant to the DGCL, the
notice shall state the means of remote communications, if any, by which
Stockholders and proxy holders may be deemed to be present in person and vote at
such meeting. Notice of a meeting of the Stockholders need not be given to any
Stockholder who signs a waiver of notice, either before or after the meeting.
Attendance of a Stockholder at a meeting, either in person or by proxy, shall of
itself constitute waiver of notice of such meeting and waiver of any and all
objections to the place of the meeting, the time of the meeting, and the manner
in which it has been called or convened, except when a Stockholder attends the
meeting solely for the purpose of stating, at the beginning of the meeting, any
such objection or objections to the transaction of business.

      3.4 Quorum. At all meetings of the Stockholders, the holders of a majority
of the outstanding shares of stock of the Corporation entitled to vote,
represented in person or by proxy, shall constitute a quorum for the transaction
of business.

      3.5 Voting. Except as otherwise required by law, the Bylaws or any lawful
agreement between or among the Stockholders, all resolutions adopted and
business transacted shall require the favorable vote of the holders of a
majority of the shares of stock represented at the meeting and entitled to vote
on the subject matter. Except as otherwise required by law, by the Certificate
of Incorporation, by filings with the Delaware Secretary of State fixing and
determining the voting rights of the stock of the Corporation or by the Bylaws,
at any meeting of the Stockholders, each Stockholder of the Corporation shall
have one vote, in person or by proxy, for each share of stock having voting
rights standing in his name on the books of the Corporation at the record date
fixed or otherwise determined for such meeting.

      3.6 Adjournment. The holders of a majority of the shares of stock
represented at a meeting, whether or not a quorum is present, may adjourn such
meeting from time to time. If a quorum is not present, the holders of the shares
of stock present in person or represented by proxy at the meeting, and entitled
to vote, shall have the power, by the affirmative vote of the holder of such
shares of stock, which represent a majority of the votes which may be cast by
the holders of such shares of stock, to adjourn the meeting to another time
and/or place. Unless the adjournment is for more than thirty (30) days or unless
a new record date is set for the adjourned meeting, no notice of the adjourned
meeting need be given to any Stockholder provided that the time, place, if any,
and the means of remote communication, if any, by which Stockholders and proxy
holders may be deemed to be present in person and vote at the adjourned meeting
were announced at the meeting at which the adjournment was taken. At the
adjourned meeting, the Corporation may transact any business which might have
been transacted at the original meeting.

      3.7 Presiding Officer. The President shall preside at meetings of the
Stockholders; provided, however, that the President may delegate his authority
to preside at meetings of the Stockholders pursuant to Section 5.2.

<PAGE>

      3.8 Written Consent of the Stockholders. Any action required to be taken
at a meeting of the Stockholders of the Corporation, or any action that may be
taken at a meeting of the Stockholders, may be taken without a meeting if a
consent in writing setting forth the action so taken shall be signed by persons
who would be entitled to vote at a meeting those shares of stock having voting
power to cast not less than the minimum number of votes that would be necessary
to authorize or take such action at a meeting at which all shares of stock
entitled to vote were present and voted. Prompt notice shall be given of the
taking of corporate action without a meeting by less than unanimous written
consent to those Stockholders on the record date whose shares of stock were not
represented on the written consent. For purposes of written consent by the
Stockholders, the record date for determining Stockholders entitled to take
action pursuant to this Section 3.8 shall be the date when the consent is first
executed and action shall be deemed taken when executed by the last necessary
signature.

                         ARTICLE IV. BOARD OF DIRECTORS

      4.1 Powers of Board. Subject to the Certificate of Incorporation, the
Bylaws, and any lawful agreement between or among the Stockholders, including
that certain Joint Venture Agreement, dated as of April 10, 2005, by and between
Bridgetech Holdings International, Inc. and Amcare Labs International, Inc. (the
"Joint Venture Agreement") and any management agreement contemplated thereby,
the business and affairs of the Corporation shall be managed by the Board.

      4.2 Number of Board; Conduct of Meetings of Board. The members of the
Board of Directors shall be determined as provided in the Joint Venture
Agreement. In the event that the Joint Venture Agreement shall no longer be in
effect, the Board shall consist of three directors, each of whom shall be
elected at an annual meeting of the Stockholders, to serve until his successor
is elected and qualified, or until his earlier death, resignation or removal.

      4.3 Removal of Board. Members of the Board of Directors shall be removed
only as provided in the Joint Venture Agreement. In the event that the Joint
Venture Agreement shall no longer be in effect, at any meeting of the
Stockholders with respect to which notice of such purpose has been given, the
entire Board or any individual director may be removed, with or without cause,
by the affirmative vote of the holders of a majority of the shares of stock of
the Corporation entitled to vote.

      4.4 Board Vacancies. Except as otherwise provided in this Section 4.4 or
in the Joint Venture Agreement, any vacancy occurring in the Board may be filled
by the affirmative vote of a majority of the remaining directors though less
than a quorum of the Board, or by the sole remaining director, as the case may
be, or, if the vacancy is not so filled, or if no director remains, by the
Stockholders. Any vacancy arising as a result of the removal of a director by
the Stockholders may be filled by the Stockholders or, if the Stockholders so
authorize, by the remaining director or directors, but only for the unexpired
term of his predecessor in office. The Board may fill a vacancy created by an
increase in the number of directors resulting from an amendment of Section 4.2,
but only for a term of office continuing until the next annual election of
directors by the Stockholders and the election and qualification of a successor.

<PAGE>

      4.5 Meetings; Notice.

            (a) Time and Location. The Board shall meet annually immediately
following the annual meeting of the Stockholders; provided that the failure to
hold the annual meeting shall not work a forfeiture or otherwise affect valid
corporate acts. A special meeting of the Board may be called at any time by the
President, or by any two directors, on ten (10) days' notice.

            (b) Notice. Notice shall be given (i) in person, either orally or in
writing (which includes a telephone call to the director, but does not include
either (A) a telephone call to such directors' assistant or (B) the leaving of a
message), (ii) by nationally recognized next business day delivery service for
next business day delivery, (iii) by fax, or (iv) by electronic mail. Such
notice shall be addressed to the director at his address as it appears on the
stock records of the Corporation or, if he is not a Stockholder, at his business
address. Notice of a special meeting may be waived by an instrument in writing.
Attendance of a director at a meeting shall constitute a waiver of notice of the
meeting and waiver of any and all objections to the place of the meeting, the
time of the meeting and the manner in which it has been called or convened,
except when a director states, at the beginning of the meeting, any such
objection or objections to the transaction of business. Any meeting of the Board
may be held within or without the State of Delaware at such place as may be
determined by the person or persons calling the meeting.

            (c) Quorum. Unless otherwise provided in the Joint Venture
Agreement, all of the directors shall constitute a quorum for the transaction of
business.

            (d) Voting. Except as otherwise provided in the Certificate of
Incorporation, these Bylaws or the Joint Venture Agreement, all resolutions
adopted and all business transacted by the Board shall require the affirmative

directors, subject to the following:

            (a) Each such committee shall have and may exercise, consistent with

of action without a meeting if a consent in writing, setting forth the action so
taken, shall be signed by all of the members of such committee and be filed with
the minutes of the proceedings of such committee). Each such committee shall
keep minutes or other records of its proceedings and shall report its actions to
the Board as requested and at regularly scheduled meetings of the Board.

            (d) The designation of any such committee and the delegation thereto

of any responsibility imposed by law.

      4.7 Reliance on Records and Third Parties. A member of the Board or a
member of any committee designated by the Board shall, in the performance of
such member's duties, be fully protected in relying in good faith upon the

      7.1 Indemnification.

      (a) General. The Corporation shall indemnify each person who is or was a
director or officer of the Corporation (including the heirs, executors,
administrators or estate of such person) or is or was serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise to the full extent permitted under DGCL
Section 145(a), (b) and (c) or any other provisions of the laws of the State of
Delaware.

      (b) Procedure. If any such indemnification is requested pursuant to the
foregoing, the Board shall cause a determination to be made (unless a court has
ordered the indemnification or indemnification is required by DGCL Section
145(c)) pursuant to DGCL Section 145(d) as to whether indemnification of the
party requesting indemnification is proper in the circumstances because he has
met the applicable standard of conduct set forth in DGCL Sections 145(a) or (b).
Upon any such determination that such indemnification is proper, the Corporation
shall make indemnification payments of liability, cost, payment or expense
asserted against, or paid or incurred by, him in his capacity as such a director
or officer to the maximum extent permitted by said sections of such laws.

      (c) Interim Payment of Expenses. Expenses incurred by a person who is or
was a director or officer of the Corporation (including the heirs, executors,
administrators or estate of such person) or is or was serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise in defending a civil or criminal
action, suit, or proceeding may be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding, as authorized by the
Board, upon receipt of an agreement or an undertaking by or on behalf of such
person to repay such amount, unless it is ultimately determined that he or she
is not entitled to be indemnified by the Corporation as authorized in, or as
permitted by, this Article 7. The Board may pay such expenses of such person
upon such other terms and conditions as the Board deems appropriate.

      (d) Subsequent Amendment. No amendment, termination or other elimination
of this Article 7 or of any relevant provisions of the DGCL or any other
applicable laws shall affect or diminish in any way the rights to
indemnification under this Article 7 with respect to any action,

<PAGE>

suit or proceeding arising out of, or relating to, any event or act or omission
occurring or fact or circumstance existing prior to such amendment, termination
or other elimination.

      (e) Other Rights. The indemnification and advancement of expenses provided
by, or granted pursuant to, the other subsections of this Section 7.1 shall not
be deemed exclusive of any other rights to which a director or officer, seeking
indemnification or advancement of expenses may be entitled under any applicable
law, agreement, vote of Stockholders or disinterested directors or otherwise,
both as to action in his official capacity and as to action in any other
capacity while holding such office; provided, however, that indemnification of a
director shall not be permitted with respect to liability (i) for any breach of
the director's duty of loyalty to the Corporation or its Stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under DGCL Section 174, or (iv) for any
transaction from which the director derived an improper personal benefit.
Nothing contained in this Article 7 shall be deemed to prohibit, and the
Corporation is specifically authorized to enter into, agreements which provide
indemnification rights and procedures permitted by the DGCL.

      (f) Continuation of Right to Indemnification. All rights to
indemnification under this Article 7 (including those arising pursuant to
subsection (e) above) shall continue as to a person who has ceased to be a
director or officer, shall inure to the benefit of heirs, executors,
administrators and the estate of such person, and shall be deemed to be a
contract between the Corporation and each such person or entity. This Article 7
shall be binding upon any successor corporation to the Corporation, whether by
way of merger, consolidation or otherwise.

      (g) Savings Clause. If this Article 7 or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify persons or entities specified in this
Article 7 to the full extent permitted by any applicable portion of this Article
7 that shall not have been invalidated and to the full extent permitted by
applicable law.

      7.2 Insurance. The Corporation may purchase and maintain insurance at its
expense, to protect itself and any such person or entity against any such
liability, cost, payment or expense whether or not the Corporation would have
the power to indemnify such person or entity against such liability, cost,
payment or expense.

                           ARTICLE VIII. MISCELLANEOUS

designated by the Board shall have authority to vote shares of stock or any
other securities owned by the Corporation and to execute proxies and written
waivers and consents in relation thereto.

See attached.

<PAGE>

                              STOCKHOLDER AGREEMENT

      THIS STOCKHOLDER AGREEMENT (this "Agreement") is made as of this ___ day
of _______, 2005, by and among _____________, a Delaware corporation (the
"Company"), and those certain individuals listed as Common Stockholders on
Schedule 1 attached hereto (collectively, the "Common Stockholders"). The Common
Stockholders and their successors and assigns, and each future stockholder of
the Company who signs a signature page to this Agreement are hereinafter
sometimes referred to collectively as the "Stockholders".

                                   Background

      A. In connection with the transactions described in that certain Joint
Venture Agreement by and among Bridgetech Holdings International, Inc.
("Bridgetech") and Amcare Labs International, Inc. ("Amcare"), dated as of April
10, 2005 (the "Joint Venture Agreement"), the Company has agreed to issue up to
1,000 shares of the Company's $.001 par value of common stock (the "Common
Stock") to Bridgetech and Amcare. Any term used herein but not defined herein
shall have the meaning given that term in the Joint Venture Agreement.

      B. The Company and the Stockholders desire to enter into this Agreement
for the purpose, among others, of prescribing the manner and terms by which the
Stockholders' shares of Common Stock (the "Shares"), may be transferred.

      C. The execution and delivery of this Agreement is a condition to the
Closing under the Joint Venture Agreement.

      In consideration of the premises and the covenants and undertakings
hereinafter set forth, the parties hereto agree as follows:

      1. CAPITALIZATION. Set forth on Schedule 1 attached hereto is a list of
all the Stockholders of the Company and their respective ownership of Shares
immediately following the Closing.

      2. TRANSFER RESTRICTIONS ON SHARES.

      (a) General. No holder of Shares shall sell, offer, assign, pledge or
otherwise dispose of any interest in any Shares (whether with or without
consideration and whether voluntarily or involuntarily or by operation of law),
except pursuant to (i) any sale of Shares to the public pursuant to an
underwritten offering registered under the Securities Act of 1933, as amended
(the "Securities Act"), or to the public through a broker, dealer or market
maker pursuant to the provisions of Rule 144 adopted under the Securities Act or
(ii) the provisions of this Section 2 or Section 3.

      (b) Permitted Transfers. A Stockholder may transfer all or a portion of
its Shares (i) in the case of a Stockholder that is an individual, to a spouse,
sibling, lineal ancestor or descendant, natural or adopted, or to a trust or
other estate planning entity for the benefit of the

<PAGE>

Stockholder or any of such persons; and (ii) in the case of a Stockholder that
is a Person other than an individual, to or among its Affiliates (clauses (i)
and (ii) collectively referred to herein as "Permitted Transferees"). As a
condition to any transfer pursuant to this Section 2(b), the transferee must
agree in writing that it and its heirs, successors and assigns, shall be subject
to and bound by the provisions of this Agreement. Notwithstanding the foregoing,
no party hereto shall avoid the provisions of this Agreement by making one or
more transfers to Permitted Transferees and then disposing of all or any portion
of such party's interest in any such Permitted Transferee. For purposes of this
Agreement, an "Affiliate" of a Person means any Stockholder, partner, member or
other equity owner of such Person or any other Person directly or indirectly
controlling, controlled by or under common control with such Person. "Person"
means an individual, a partnership, a corporation, a limited liability company,
an association, a joint stock company, a trust, a joint venture, an
unincorporated organization and a governmental entity or any department, agency
or political subdivision thereof.

      (c) Right of First Refusal.

            (i) Notice of Offer to Sell Shares. Except as provided in Sections
      2(a) and 2(b) above, if any Stockholder shall desire to sell, exchange or
      in any other manner dispose of all or any of the Shares now owned or
      hereafter acquired by it (such Stockholder being hereinafter referred to
      as the "Selling Stockholder"), it must first receive a bona fide written
      offer from a third-party prospective purchaser to purchase such Shares,
      and then deliver to other Stockholders (the "Non-Selling Stockholders") a
      written notice ("Notice") containing the following information:

            (A)   The name and address of the prospective purchaser of such
                  Shares;

            (B)   The number of Shares that the Selling Stockholder desires to
                  sell;

            (C)   The price being offered to the Selling Stockholder and, in
                  reasonable detail, the terms of payment and any other terms
                  and conditions of such offer, including but not limited to the
                  fair market value (as hereinafter defined) of any non-cash
                  consideration; and

            (D)   The proposed closing date for the transaction, which shall be
                  not less than sixty-five (65) days or more than one hundred
                  twenty (120) days after the date of delivery of the Notice.

            (ii) Offer to Non-Selling Stockholders. For a period of sixty (60)
      days after the giving of the Notice by the Selling Stockholder, the
      Non-Selling Stockholders shall have the option to purchase all or any of
      their pro-rata portion of the Shares that are proposed to be sold at the
      price and upon the terms and conditions set forth in the Notice. Such
      option shall be exercisable by written notice from such Non-Selling
      Stockholder to the Selling Stockholder within such sixty (60) day period.
      A failure by any Non-Selling Stockholder to give written notice of
      exercise within such sixty (60) day period shall be deemed a rejection by
      such Non-Selling Stockholder of its option to purchase. If a Non-
<PAGE>

      Selling Stockholder does not exercise its option to purchase all the
      Shares to which it is first entitled, each remaining Non-Selling
      Stockholder shall then have the option to purchase its pro rata portion of
      the Shares that will not be purchased by the other Non-Selling
      Stockholders, which option shall be exercisable by notice in writing to
      the Selling Stockholder and to each of the other Non-Selling Stockholders
      within five (5) days after the date of express rejection by all other
      Non-Selling Stockholders or the expiration of the options to the
      Non-Selling Stockholder who did not elect to purchase such Shares,
      whichever is earlier. For purposes of the foregoing sentence, the Shares
      available for purchase shall be allocated pro rata among the Non-Selling
      Stockholders desiring to purchase such Shares, which allocation shall be
      based on the number of Shares owned by each Non-Selling Stockholder in
      relation to the total number of Shares held by all Non-Selling
      Stockholders who wish to purchase Shares.

            (iii) Non-Cash Consideration for Shares. If any consideration to be
      received by a Selling Stockholder from a prospective purchaser of its
      Shares consists of property other than cash, then the Non-Selling
      Stockholders who exercise their option(s) to purchase the Selling
      Stockholder's Shares, may deliver to the Selling Stockholder, in payment
      of the non-cash portion of the purchase price for the Shares proposed to
      be sold, an amount of cash equal to the fair market value of the non-cash
      consideration that has been offered to the Selling Stockholder. For
      purposes hereof, the "fair market value" of non-cash consideration shall
      in each case be agreed upon by the Selling Stockholder and the Non-Selling
      Stockholder purchasing its Shares as provided in this Agreement, or, in
      the absence of such agreement, such "fair market value" shall be
      determined by an appraisal thereof by three independent qualified
      appraisers, one being selected by the Selling Stockholder, one being
      selected by the Non-Selling Stockholder hereto desiring to purchase the
      Selling Stockholder's Shares, and the third appraiser being selected by
      the two appraisers thus chosen. The cost of any such appraisal shall be
      borne equally by the parties to the appraisal proceeding. All decisions to
      be made by the Non-Selling Stockholders purchasing Shares from the Selling
      Stockholder shall be made by the affirmative vote of those holding a
      majority of Shares held by all such Non-Selling Stockholders. Any closing
      provided for herein may be extended for such reasonable period of time as
      may be necessary in order for a required appraisal to be completed. In the
      event of an appraisal pursuant to this Section 2, the parties agree to be
      bound thereby.

            (iv) Closings. If any Non-Selling Stockholder shall exercise an
      option to purchase that is granted to such Non-Selling Stockholder in this
      Section 2, the closing of the purchase and sale transaction shall be held
      at the principal office of the Company on a date designated by the
      purchaser or purchasers, which date in no event shall be later than 90
      days after the Selling Stockholder gives the Notice. If there is more than
      one Non-Selling Stockholder purchasing the Shares, the Selling Stockholder
      may require that all such Non-Selling Stockholders close concurrently on
      the same date.

            (v) Right to Transfer. If the Non-Selling Stockholders do not elect
      to purchase all the Shares that a Selling Stockholder desires to sell,
      subject to Section 2(d) below, the Selling Stockholder shall have the
      right to sell the Shares to the prospective purchaser named in the Notice
      on the terms and conditions set forth in the Notice until such date that
      is 120 days after the date of the Notice. In addition, as a condition to
      any

<PAGE>

      such sale, the purchaser of the Shares must agree in writing that it and
      its heirs, successors and assigns, shall be subject to and bound by the
      provisions of this Agreement. In the event that the Selling Stockholder
      does not sell or otherwise dispose of such Shares within the such period
      of time, the right of first offer provided for in this Section 2(c) shall
      continue to be applicable to any subsequent disposition of such Shares.

      (d) Right of Co-Sale (Tag-Along). In the event that a Selling Stockholder
proposes to dispose of Shares representing not less than fifteen percent(15%) of
the then-outstanding Shares to a third party (other than in accordance with
Sections 2(a) and 2(b)), after compliance with the provisions of Section 2(c),
the other Stockholders shall have the right to offer and sell a proportionate
number of Shares to the prospective purchaser acquiring such Selling
Stockholder's Shares, at the same price and on the same terms and conditions as
outlined in the Notice (the "Co-Sale Right"), in accordance with the following
procedure:

            (i) Such Selling Stockholder shall, prior to sale and after
      compliance with the provisions of Section 2(c), give notice (the "Co-Sale
      Notice") to the Stockholders of the Co-Sale Right and the aggregate number
      of Shares proposed to be sold to the third-party purchaser (taking into
      account any Offered Shares to be purchased by Non-Selling Stockholders
      pursuant to Section 2(c) above).

            (ii) Each Stockholder shall have fifteen (15) days after receipt of
      such notice to determine if it desires to offer Shares to the third-party
      acquiring such Selling Stockholder's Shares. A failure by a Stockholder to
      give written notice of exercise within such fifteen (15) day period shall
      be deemed a rejection by such Stockholder of its Co-Sale Right.

            (iii) Such Selling Stockholder shall cause the proposed purchaser to
      offer, in writing to each Stockholder, if Stockholder has elected to
      participate in the sale of the Shares (a "Participating Stockholder"), to
      purchase at the offer price indicated in the Co-Sale Notice, all or any
      part of that number of Shares equal to the product obtained by multiplying
      (i) the aggregate number of offered Shares (less any Offered Shares to be
      purchased by Non-Selling Stockholders pursuant to Section 2(c) above) by
      (ii) a fraction, the numerator of which is the number of Shares owned by
      such Participating Stockholder immediately before the time of the sale and
      the denominator of which is the sum of (x) the number of the Shares then
      owned by all Participating Stockholders and (y) the number of Shares owned
      by the Selling Stockholder. The Shares to be transferred by the Selling
      Stockholder shall be correspondingly reduced by the aggregate sum of such
      product for such Participating Stockholder.

            (iv) A Participating Stockholder shall effect its participation in
      the sale by promptly delivering to the Selling Stockholder for transfer to
      the proposed purchaser one or more certificates, properly endorsed for
      transfer, which represent the type and number of Shares that such
      participant elects to sell.

            (v) The stock certificate or certificates that the Participating
      Stockholder delivers to the Selling Stockholder pursuant to subsection
      (iv) above shall be transferred

<PAGE>

      to the proposed purchaser in consummation of the sale of the offered
      Shares (together with the Selling Stockholders Shares) pursuant to the
      terms and conditions specified in the Co-Sale Notice, and the Selling
      Stockholder shall concurrently therewith remit to the Participating
      Stockholder that portion of the sale proceeds to which the Participating
      Stockholder is entitled by reason of its participation in such sale.

<PAGE>

            (e) Prohibited Transfers Void. Any purported transfer of Shares in
violation of this Agreement shall be void and shall not transfer any interest or
title to any Shares to the purported transferee. The Company shall not be
required to transfer on its books any Shares sold or transferred in violation of
any of the provisions set forth in this Agreement or to treat as owner of those
Shares or to pay dividends to any transferee to whom any of those Shares shall
have been so sold or transferred.

      3. SALE OF THE COMPANY (Drag-along Rights).

      (a) If at any time the Board, in accordance with the Bylaws and the Joint
Venture Agreement, approves a sale of all or substantially all the Company's
assets (determined on a consolidated basis) or a sale or exchange of all or
substantially all the Company's outstanding capital stock (whether by merger,
sale, recapitalization, consolidation, reorganization, combination or otherwise)
to any third party in an arm's-length transaction (an "Approved Sale"), each
Stockholder shall vote for, consent to and raise no objections against such
Approved Sale and shall waive any dissenters' rights, appraisal rights or
similar rights in connection therewith. If the Approved Sale is structured as a
sale of stock, each Stockholder shall agree to sell all its Shares and rights to
acquire Shares on the terms and conditions approved by the Board. Each
Stockholder shall take all necessary and desirable actions in its capacity as a
Stockholder in connection with the consummation of the Approved Sale as
requested by the Company (including attendance at meetings in person or by proxy
for purposes of obtaining a quorum and execution of written consents in lieu of
meetings).

      (b) In order to secure each Stockholder's obligation to vote its Shares
and other voting securities of the Company in accordance with the provisions of
this Section 3, each Stockholder hereby appoints the Secretary of the Company
(the "Representative") as true and lawful proxy and attorney-in-fact, with full
power of substitution, to vote all of his, her or its Shares and other voting
securities of the Company for the approval and consummation of an Approved Sale
and all such other matters as expressly provided for in this paragraph. The
Representative may exercise the irrevocable proxy granted to it hereunder at any
time any Stockholder fails to comply with the provisions of this paragraph. The
proxies and powers granted by each Stockholder pursuant to this paragraph (c)
are coupled with an interest and are given to secure the performance of each
Stockholder's obligations and duties under this Section 3. Such proxies and
powers shall be irrevocable for so long as such Stockholder holds any Shares and
shall survive the death, incompetency, disability, bankruptcy or dissolution of
such Stockholder and the subsequent holders of his, her or its Shares.

      (c) The provisions of this Section 3 shall terminate upon the consummation
of an initial public offering by the Company of its debt or equity securities.

      4. REPRESENTATIONS AND WARRANTIES. Each Stockholder represents and
warrants that (a) this Agreement has been duly authorized, executed and
delivered by such Stockholder and constitutes the valid and binding obligation
of such Stockholder, enforceable in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, arrangement, moratorium, fraudulent conveyance or other similar
laws or by general equitable principles, and (b) such Stockholder has not
granted and is not a

<PAGE>

party to any proxy, voting trust or other agreement which is inconsistent with,
conflicts with or violates any provision of this Agreement. No holder of Shares
shall grant any proxy or become party to any voting trust or other agreement
that is inconsistent with, conflicts with or violates any provision of this
Agreement.

      5. LEGEND ON SHARE CERTIFICATES. Upon the execution of this Agreement, the
certificates of Common Stock subject to this Agreement shall bear the following
legend:

      "THE VOTING AND TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE
      ARE SUBJECT TO THE PROVISIONS OF THE STOCKHOLDER AGREEMENT DATED AS OF MAY
      ___, 2005, AS AMENDED AND IN EFFECT FROM TIME TO TIME, AMONG THE COMPANY
      AND THE STOCKHOLDERS NAMED THEREIN, A COPY OF WHICH IS ON FILE AT THE
      OFFICES OF THE COMPANY."

<PAGE>

      6. TRANSFERS; FUTURE SALES; STOCK DIVIDENDS. Prior to (i) the Company
issuing shares to any Person, or (ii) any holder of Shares transferring any
Shares (other than pursuant to an Initial Public Offering) to any Person, the
Company or such holder shall cause the prospective Stockholder or transferee to
be bound by this Agreement and to execute and deliver to the Company and the
other Stockholders a counterpart signature page to this Agreement in the form of
Exhibit A hereto. Such Stockholder or transferee of Shares of Common Stock shall
be deemed to be a Stockholder hereunder in respect of those shares from and
after the date such transferee executes this Agreement. Promptly following such
action, the Company shall amend Schedule 1 attached hereto and provide such
Schedule 1, as amended, to the other parties to this Agreement. If, from time to
time, during the term of this Agreement there is any stock dividend, stock split
or similar other change in the character or amount of any of the outstanding
Common Stock of the Company, then in such event any and all such new,
substituted or additional securities to which the Stockholders are entitled by
reason of their ownership of Common Stock shall be immediately subject to the
terms of this Agreement with the same force and effect as the shares of capital
stock presently subject to this Agreement.

      7. TERMINATION OF AGREEMENT. This Agreement shall terminate upon the
earlier of (a) the consummation of a Qualified Public Offering (as defined
below) of any of its Shares, (b) the liquidation or sale of the Company (whether
by sale or transfer of more than 50% of its stock through a sale or merger, or a
sale of all or substantially all of its assets), or (c) as provided in the Joint
Venture Agreement. For purposes of this Agreement, a "Qualified Public Offering"
means a firm commitment underwritten Public Offering (as defined below) of
shares of the Company's Common Stock in which the net proceeds payable to the
Company shall be at least $50 million (before payment of underwriters' discounts
and commissions). "Public Offering" means any offering by the Company of its
equity or debt securities to the public pursuant to an effective registration
statement under the Securities Act of 1933, as then in effect, or any comparable
statement under any similar federal statute then in force (other than an
offering pursuant to a registration on Form S-4, S-8 or any comparable or
successor forms); or (c) the written consent of the parties to this Agreement.

      8. AGREEMENT BINDING. This Agreement shall inure to the benefit of and be
binding upon the Stockholders and each of their heirs, successors and permitted
assigns. It shall also be binding upon any transferee and their heirs,
successors and permitted assigns of such transferee who has received any Shares.

      9. ENTIRE AGREEMENT. This Agreement, the Joint Venture Agreement and the
documents listed in the Joint Venture Agreement constitute the entire agreement
of the parties as to the subject matter herein contained, superseding any and
all prior or contemporaneous oral and prior written agreements, understandings,
letters of intent or commitment letters.

      10. AMENDMENT OR WAIVER OF AGREEMENT. Except as otherwise expressly
provided herein, any term of this Agreement may be amended and the observance of
any term of this Agreement may be waived (either generally or in a particular
instance, either retroactively or prospectively and either for a specified
period of time or indefinitely) with the written consent of (a) the Company and
(b) each of the Stockholders. Any amendment or waiver effected in accordance
with this Section 10 shall be binding upon each Stockholder and each

<PAGE>

transferee of the Shares. Notwithstanding anything to the contrary in this
Section 10, subject to compliance with the terms of this Agreement, the Company
shall be entitled to include additional Stockholders as parties to this
Agreement in accordance with the provisions of Section 6 above, and to treat
such purchasers as Stockholders hereunder, by amending Schedule 1 attached
hereto and providing such Schedule 1, as amended, to the other parties to this
Agreement.

      11. NOTICES. All communications and notices provided for hereunder shall
be sent in accordance with the notice provision in the Joint Venture Agreement.

      12. GOVERNING LAW. This Agreement is made pursuant to, and will be
governed by and construed in accordance with, the laws of the State of Delaware
applicable to contracts executed and to be performed wholly within such state.

      13. INVALIDITY. If any portion or portions of this Agreement shall be
adjudged, declared, held, or ruled to be invalid for any reason, such invalidity
shall not be deemed to impair the validity of any other provision of this
Agreement.

      14. GENDER AND NUMBER REFERENCES. All references to any gender shall
include all genders; all references to the singular shall include the plural;
and all references to the plural shall include the singular, unless the context
indicates otherwise.

      15. REMEDIES. The parties hereto shall be entitled to enforce their rights
under this Agreement specifically, to recover damages by reason of any breach of
any provision of this Agreement and to exercise all other rights existing in
their favor. The parties hereto agree and acknowledge that money damages would
not be an adequate remedy for any breach of the provisions of this Agreement and
that the Company and any Stockholder may in its sole discretion apply to any
court of law or equity of competent jurisdiction for specific performance and/or
injunctive relief (without posting a bond or other security) in order to enforce
or prevent any violation of the provisions of this Agreement.

      16. BUSINESS DAYS. If any time period for giving notice or taking action
hereunder expires on a day which is a Saturday, Sunday or legal holiday in the
state in which the Company's chief executive office is then located, the time
period shall automatically be extended to the business day immediately following
such Saturday, Sunday or legal holiday.

      17. DESCRIPTIVE HEADINGS, ETC. The descriptive headings of this Agreement
are inserted for convenience only and do not constitute a part of this
Agreement. The use of the term "including" herein shall mean "including without
limitation."

      18. NO STRICT CONSTRUCTION. The parties hereto have participated jointly
in the negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as it was drafted jointly by the parties hereto, and no presumption or burden of
proof shall arise favoring or disfavoring any party hereto by virtue of the
authorship of any of the provisions of this Agreement.

      19. COUNTERPARTS. This Agreement may be executed in multiple counterparts
(including by means of faxed signature pages), each of which shall be an
original and all which taken together shall constitute one and the same
agreement.
