be opportunities to distribute the Product in the OTC Market in countries
outside the Territory. If during the Term, either party identifies such an

other items) the price, term, minimum purchase requirements, and other principal
terms under which OSUR is willing to grant Distributor rights to the Product in
the OTC Market in such country. For a period of thirty (30) days following the
date of the Product Notice, the parties shall negotiate in good faith regarding
the terms and conditions of a distribution agreement with respect thereto. If,
following such 30-day period, the parties have not executed and delivered a
mutually acceptable form of distribution agreement, then (i) Distributor's right
of first negotiation with respect to all countries outside the Territory under
this Section 2.4 shall terminate and (ii) OSUR shall be free to offer the right
to distribute the Product in the OTC Market in any country outside the
Territory. Schedule 2.4 herein is a complete and accurate list (as of the date

by OSUR with a third party to distribute such product.

     2.5     INDEPENDENT CONTRACTOR. Distributor is, and at all times shall be,
an independent contractor. Nothing contained in this Agreement shall he
construed as constituting Distributor as an agent, partner, joint venturer or
employee of OSUR, or cause OSUR to be liable for any of the debts or obligations
of Distributor; nor shall Distributor have the right or authority to act for or
incur any liability or obligation of any kind, express or implied, in the name
of or on behalf of OSUR or its Affiliates.

3.   OBLIGATIONS.

directly or indirectly, import, promote, market, use, sell or otherwise
distribute or provide (or arrange any promotion, marketing, use, sale,
distribution or provision of) the Product (a) in any country or territory
outside of the Territory (unless Distributor has acquired additional
distribution rights to such countries or territories from OSUR) or (b) in any
market other than the OTC Market. Distributor shall notify OSUR of any sale or
order of Product or other occurrence that violates this Section 3.1.2 promptly
upon learning thereof.

             3.1.3       SALES LEADS OUTSIDE OF THE TERRITORY OR OTC MARKET.
Distributor shall refer to OSUR all sales leads that come to its attention with
respect to the use of the Product outside of the Territory or OTC Market and, as
soon as reasonably possible, inform OSUR of the identity of such sales lead.

             3.1.4       PRODUCT LABELING; SUPPORTING MATERIALS; TRAINING.
Distributor shall ensure that all Product purchased hereunder is distributed
into the OTC Market only with the labeling, inserts and instructions approved in
writing by OSUR. Distributor shall produce and use sufficient quantities of
promotional materials, including sales aids, brochures, product briefs,
advertisements and similar materials relating to the Product (including
references and descriptions on its website) for purposes of promoting,
marketing, selling and distributing the Product in the OTC Market; provided that
all such materials (in print, electronic or any other type of media) shall be
subject to the written approval of OSUR prior to their use (which approval shall
not be unreasonably withheld or delayed). In addition, Distributor shall provide
appropriate customer support to maintain and foster customer satisfaction.

             3.1.5       COMPLIANCE WITH LAWS. Distributor shall comply with all
applicable treaties, laws, rules and regulations in connection with its
promotion, marketing, use, sale or distribution of the Product in the OTC
Market, its supply of the Distributor Components (as defined below) and its
performance of its obligations under this Agreement. Without limiting the
generality of the foregoing, Distributor shall comply with all applicable FDA or
other regulatory approvals, clearances or registrations obtained by OSUR for the
sale or distribution of the Product in the OTC Market.

             3.1.6       COMPETITION. During the Term, Distributor and its
Affiliates shall not, directly or indirectly, (a) import, market, manufacture,
use, promote, sell, distribute or purchase any cryosurgical wart or lesion
removal product that directly competes with the Product (a "Competing Product")
or (b) engage in, provide services for or acquire or hold an interest in any
company, entity or business (as owner, stockholder, partner, co-venturer,
director, officer, employee, consultant or otherwise) that imports,
manufactures, markets, promotes, sells or distributes a Competing Product.
Notwithstanding the foregoing, nothing contained herein shall be deemed to
prevent or preclude an entity not party to this Agreement from acquiring an
equity ownership interest in Distributor (the "Acquiring Party") under
circumstances where such Acquiring Party becomes an Affiliate of Distributor and
has a business, existing prior to such acquisition, under which it imports,
markets, manufactures, uses, promotes, sells or distributes a Competing Product.
In the event of such an acquisition by an Acquiring Party, OSUR shall have the

                                        4
<Page>

right to terminate this Agreement upon not less than twelve (12) months prior
written notice to Distributor. If any provision of this Section 3.1.6 shall be
held unenforceable because of scope, duration or area of its applicability, it
shall be deemed modified to the extent necessary to make it enforceable, while
preserving its intent.

             3.1.7       MARKETING PLAN. Distributor shall develop a written
annual plan for the marketing and sale of the Product in the OTC Market and
Territory. Distributor shall deliver such plan to OSUR within thirty (30) days
after the date of this Agreement. In addition, Distributor shall provide OSUR
with a written update of its marketing and sales plan at least sixty (60) days

acknowledge that OSUR has obtained FDA clearance to manufacture, market, sell,
use and distribute the Product in the OTC Market in the United States, but has
not yet sought any required regulatory approval, clearance or registration in
Canada. OSUR shall have no obligation to sell or supply Product to Distributor
for sale or distribution in Canada, and Distributor shall have no right to
distribute Product in Canada, until OSUR obtains any required regulatory
approvals, clearances or registration for the import, distribution and sale of
the Product in the OTC Market in Canada. OSUR shall use commercially reasonable
efforts to obtain such required regulatory approvals, clearances and
registrations for the Product in Canada, but there is no assurance,
representation or warranty that OSUR will be successful in such efforts and its
failure to obtain any such regulatory approval, clearance or registration in
Canada shall not constitute a breach of this Agreement. OSUR shall use
commercially reasonable efforts to maintain all approvals, clearances or
registrations of the FDA and, to the extent obtained, any regulatory authority
in Canada, for the manufacturing, marketing, sale, use or distribution of the
Product in the OTC Market in the Territory. All such approvals, clearances and
registrations shall be maintained in the name of OSUR. Distributor shall, at
OSUR's expense, cooperate and provide reasonable assistance and technical
support in obtaining and maintaining all such approvals, clearances and
registrations; OSUR shall comply with all applicable treaties, laws, rules and
regulations within the Territory, including the Quality System Regulations
promulgated by the FDA, in connection with its provision of the Product to
Distributor and its performance of its obligations under this Agreement.

             3.2.2       TRAINING. OSUR shall provide reasonable technical
support and training to Distributor in the use and performance of the Product,
which training shall be at times and places and for durations mutually agreed to
by the parties.

     3.3     TECHNICAL SUPPORT. OSUR shall provide and maintain, at its own
expense, adequate support services and a staff properly trained in all aspects
of the Product to provide the Distributor with such levels of technical support

current and reasonably anticipated sales volumes of the Product in the OTC
Market.

                                       ***

                         (b)   The Parties acknowledge that the Total Assembly
Contractor Costs for Product to be distributed in Canada ("Canadian Product")
may be different than as set forth above because of different or additional
labeling requirements in Canada. OSUR shall use commercially reasonable efforts
to minimize any increase in such costs for Canadian Product. In the event the
Total Assembly Contractor Costs for Canadian Product are different than as set
forth above, the Price for such Canadian Product shall be determined by
incorporating such different costs in the foregoing formula and the Price, as
recalculated, shall be the Price for Canadian Product. Nothing in this Section

United States. Canadian Product purchased at a different Price determined in
accordance with this Section 4.4.1 (b) shall only be distributed by Distributor

the U.S. Department of Labor for Urban Wage Earners and Clerical Workers (Base

and/or publication of the Index shall be transferred to any other governmental
department, bureau, or agency, or shall be discontinued, then the index most
nearly the same as the Index shall be used.

             4.4.3       TAXES; FREIGHT. Prices for Product are EX WORKS

     10.1    CONFIDENTIAL INFORMATION.

             10.1.1      DEFINITION OF "CONFIDENTIAL INFORMATION". As used in
this Agreement, the term "Confidential Information" shall, subject to Section

             10.1.2      OBLIGATIONS OF CONFIDENTIALITY AND NON-USE.

                         (a)   During the term and at all times thereafter,
neither Distributor nor OSUR shall disclose any of the other party's
Confidential Information. The foregoing shall not prohibit disclosures: (i) made
to such party's employees, agents or advisors who have a "need to know" the
other party's Confidential Information to the extent necessary to perform such
party's duties and obligations, or to enforce such party's rights, under this
Agreement; or (ii) compelled to be made by any requirement of law or pursuant to
any legal or investigative proceeding before any court, or governmental or
regulatory authority, agency or commission so long as the party so compelled to
make disclosure of Confidential Information pertaining to the other party
provides prior written notice to such other party and uses its commercially
reasonable efforts to cooperate with such other party to obtain a protective
order or other similar determination with respect to such Confidential
Information.

                         (b)   During the Term and at all times thereafter,
Distributor and OSUR shall not use any of the other party's Confidential
Information for its own direct or indirect benefit, or the direct or indirect
benefit of any third party, except that each of Distributor and OSUR may use the
other party's Confidential Information to the extent necessary to perform its
duties and obligations, or to enforce such party's rights, under this Agreement.

                         (c)   Each of Distributor and OSUR shall (i) take
reasonable steps, whether by instruction, agreement, or otherwise, to cause its
employees, agents and advisors who may have access to Confidential Information
of the other party, to comply with its obligations under this Section 10 and
(ii) shall be liable for the breach of this Section 10 by any of its employees,
agents or advisors who may have access to Confidential Information of the other
party.

     10.2    EXCEPTIONS. Confidential Information shall not include information
that: (a) is available from governmental agencies under the United States
Freedom of Information Act; (b) a party can prove on the basis of the written
record, was known by the receiving party at time of disclosure; (c) the
receiving party can prove on the basis of the written record to have been
independently developed for the receiving party after the time of disclosure by
employees or third parties who have not had access to corresponding Confidential
Information; or (d) was received by the receiving party, without restriction,
from a third party not under any obligation to the other party not to disclose
it and otherwise not in violation of the other party's rights.

     10.3    REMEDIES. Any breach of the restrictions contained in this Section
10 by either Distributor or OSUR is a material breach of this Agreement, which
may cause irreparable harm to the other party entitling such other party to
injunctive relief in addition to all other legal remedies.

     10.4    PRESS RELEASE. The parties acknowledge that it is their intention
to issue a press release concerning the execution of this Agreement. The parties
shall cooperate in

                                       17
<Page>

the preparation of such a release, which shall be subject to approval (not to be
unreasonably withheld or delayed) of both parties.

11.  TERM AND TERMINATION.

     11.1    TERM. The term of this Agreement shall begin on the Effective Date
and end on the last day of the fifth Contract Year or on such earlier date as
this Agreement may be terminated pursuant to Section 11.2 of this Agreement (the
"Initial Term"). Thereafter, this Agreement shall automatically be renewed for
successive periods of one (1) year each (each, a "Renewal Term," and together
with the Initial Term, the "Term") so long as Distributor has met its minimum
purchase commitment under Section 6.2 for each Contract Year.

     11.2    TERMINATION.

             11.2.1      BY REASON OF MATERIAL BREACH. This Agreement may be
terminated by either Distributor or OSUR upon notice if the other party
materially breaches any term or condition of this Agreement (other than a breach
covered by Section 11.2.2) and fails to remedy the breach within thirty (30)
days after being given notice thereof.

             11.2.2      BY REASON OF FAILURE TO PAY AMOUNTS OWING. Either OSUR
or Distributor shall have the right to terminate this Agreement if the other
party shall have failed to pay timely any amounts due under this Agreement which
nonpayment has not been cured within thirty (30) days of receipt of notice
thereof.

             11.2.3      FAILURE TO MEET MINIMUM PURCHASE COMMITMENTS. If
Distributor fails to order, accept delivery and pay for the volume of Products
identified in Section 6.2 as the minimum purchase commitment for any Contract
Year, then OSUR shall have the right at any time to convert Distributor's rights
hereunder to non-exclusive rights by giving Distributor written notice of such
action at least thirty (30) days prior to the effective date of such action. If
Distributor fails to order, accept delivery and pay for at least 150,000 Units
of the Products in any Contract Year, then OSUR shall have the right to then
terminate this Agreement by giving Distributor written notice of such action at
least thirty (30) days prior to the effective date of such action.

             11.2.4      BY REASON OF BANKRUPTCY OR SIMILAR PROCEEDINGS. This
Agreement may be terminated in its entirety by either party upon notice if the
other party: (a) becomes the subject of any voluntary or involuntary proceeding
under the U.S. Bankruptcy Code or state insolvency proceeding and such
proceeding is not terminated within sixty (60) days of its commencement; or (b)
ceases to be actively engaged in business.

             11.2.5      BY REASON OF INSURANCE CHANGES. If (i) OSUR experiences
a material increase in the cost of obtaining or maintaining liability insurance
coverage as a direct consequence of losses related to the sale or distribution
of Product into the OTC Market and Distributor does not agree to an increase in
the Price to reimburse OSUR for such increased costs, then OSUR shall have the
right to terminate this Agreement upon

                                       18
<Page>

not less than one hundred eighty (180) days written notice to Distributor, or
(ii) OSUR is no longer able to obtain or maintain liability insurance coverage
as a result of this Agreement or the sale or distribution of Product into the
OTC Market, then OSUR shall have the right to terminate this Agreement
immediately upon written notice to Distributor.

     11.3    EFFECT OF TERMINATION.

             11.3.1      SUBSISTING OBLIGATIONS. Termination or expiration of
this Agreement shall not relieve the parties of any obligation arising prior to
the effective date of such termination or expiration and shall not constitute a
waiver of any right of the parties under this Agreement as a result of breach or
default.

             11.3.2      REMEDIES UPON BREACH. If this Agreement is validly
terminated by either Distributor or OSUR pursuant to Section 11.2 of this
Agreement, then subject to the limitations set forth in Sections 7.2, 7.3 and
12.5 of this Agreement, any and all rights and remedies available to the
non-breaching party, whether under this Agreement, at law or in equity shall be
preserved and survive the termination of this Agreement.

             11.3.3      RETURN OF CONFIDENTIAL INFORMATION. Upon expiration of
this Agreement or its termination by either party, each party, as the other may
direct, shall destroy or return to the other promptly all tangible materials
provided to it by the other that embody the other's Confidential Information and
shall erase or delete all such Confidential Information embodied in any
magnetic, optical or similar medium or stored or maintained on any information
storage or retrieval device, and shall provide an officer's certificate
regarding such destruction, return, erasure or deletion. Notwithstanding the
foregoing, and subject to the provisions set forth in Section 10 of this
Agreement, each party's outside legal counsel may retain one (l) copy of such
materials for archival purposes.

             11.3.4      INVENTORY. Following expiration of this Agreement or
its termination by either party, (i) Distributor may continue selling any
inventory of Product remaining in its possession for a period of six (6) months
after such expiration or termination and (ii) OSUR may complete, or cause the
Assembly Contractor to complete, assembly of Product with its or the Assembly
Contractor's remaining inventory of components and Distributor shall purchase
such Product and any other finished Product inventory held by OSUR or the
Assembly Contractor at the Price set forth therein and, at OSUR's request, all
remaining components not then assembled into Product remaining in OSUR's or the
Assembly Contractor's inventory at OSUR's cost therefor and Distributor may sell
such Product and components without limitation as to time.

expiration or termination of this Agreement for any reason: Section 1, 2.3 (last
sentence only), 4.3, 4.4.1, 4.4.3, 4.8, 4.9, 5.3, 5.4, 7, 8 ,9, 10, 11.3, and

     12.3    FORCE MAJEURE. Notwithstanding anything to the contrary set forth
herein, neither party shall be liable in damages, nor shall either party have
the right to terminate this Agreement for any delay or default in performing any

governmental restrictions or regulations, wars or insurrections, strikes, fire,
floods, work stoppages, lack of materials, and unforeseen occurrences or other
occurrences beyond the control of the affected party; provided, however, that

unenforceable or void, this Agreement shall continue in full force and effect
without such provision; provided that this severability provision shall not be
effective if it materially changes the economic benefit of this Agreement to

constitute one and the same instrument. A facsimile transmission of a signed

Agreement, Distributor and OSUR shall bear their own respective expenses
incident to the preparation, negotiation, execution and delivery of this
Agreement and to the performance of their respective obligations under this

             12.13.1     AGREEMENT TO UTILIZE ALTERNATE DISPUTE RESOLUTION.
Except for matters which relate to the enforcement of Section 10 of this
Agreement, which

                                       21
<Page>

matters shall not be required to be submitted to mediation or arbitration, any
controversy or claim between Distributor and OSUR arising out of or relating to
this Agreement, or any breach of this Agreement, including without limitation,
any claim that this Agreement, or any part thereof, is invalid, illegal or
otherwise voidable or void, shall be submitted to neutral third party dispute
resolution in the form of mediation before a mutually selected and agreed upon
mediator who shall be neutral and experienced in the type of business
contemplated herein. Should the parties be unable to agree on a mediator or
should mediation fail, the parties shall then submit the dispute to arbitration
before and in accordance with the then current commercial arbitration rules of
the American Arbitration Association. Judgment upon an arbitration award may be
entered in any court having competent jurisdiction and shall be binding, final
and non-appealable. No punitive or exemplary damages shall be awarded against
either Distributor or OSUR. This Section 12.13.1 shall be deemed to be
self-executing, and in the event either party fails to appear at any properly
noticed arbitration proceeding, an award may be entered against such party
notwithstanding said failure to appear. Such arbitration shall take place in a
neutral location as the parties may mutually agree. Each party shall bear its
own costs incurred in connection with the mediation or arbitration proceeding.

             12.13.2     RIGHT TO SEEK INJUNCTIVE RELIEF PRESERVED. Nothing in
the Agreement shall be construed as limiting or precluding either party from
bringing any action in any court of competent jurisdiction for injunctive or
other extraordinary relief as such party deems necessary or appropriate to
compel the other party to comply with its obligations under Section 10 of this
Agreement.

             12.13.3     ENTIRE AGREEMENT. This Agreement constitutes the entire
and exclusive agreement and understanding between Distributor and OSUR with
respect to the subject matter of this Agreement, and supersedes and cancels all
previous negotiations, agreements, and commitments, whether oral or in writing,
in respect to the subject matter of this Agreement.
