Exhibit A hereto, which Exhibit is made a part of this Agreement, Wildform will
provide to On2 the services indicated on such Exhibit (the "Transition
Services") during the time period for each such Transition Service set forth in
such Exhibit (hereinafter referred to as the "Time Periods" for all of the
Transition Services, and the "Time Period" for each Transition Service).

      2.2 Personnel. In providing the Transition Services, Wildform, as it deems
necessary or appropriate in its sole discretion, may (i) use its personnel, and
(ii) employ the services of third parties to the extent such third party

Amount in accordance with the Asset Purchase Agreement, Wildform shall deliver
each Deliverable in accordance with the timeframe (the "Timeframe") set forth in
Exhibit B, which Exhibit is made a part of this Agreement. On2 will use
commercially reasonable efforts to cooperate with Wildform as necessary in
completing the Development Work and delivery of the Deliverables. Upon receipt
of each Deliverable, On2 shall have a period of thirty (30) working days within
which to inspect such Deliverable based upon the relevant Specification (an
"Acceptance Period"). Should On2 find that any Deliverable does not
substantially conform to the relevant Specification, On2 shall promptly so
notify Wildform in writing, which notice shall provide sufficiently detailed
explanation of the non-conformities so as to allow Wildform to reproduce them
(any such notice is referred to herein as a "Nonconformance Notice"). Each of
the Deliverables shall be deemed accepted by On2 unless On2 delivers to Wildform
a Nonconformance Notice within thirty (30) business days of the delivery of such
Deliverable. In the event that Wildform receives such Nonconformance Notice from
On2, Wildform shall make commercially reasonable efforts to modify such
Deliverable and re-deliver it to On2 after any such modification is completed.
Each Deliverable shall be deemed to have been accepted by On2 when either (i)
On2 notifies Wildform in writing of its acceptance of such Deliverables or (ii)
On2 does not deliver a Nonconformance Notice to Wildform within the Acceptance
Period. Notwithstanding anything herein to the contrary, On2 shall not
unreasonably withhold acceptance of any Deliverable.

      3.2 Program Errors. During the Term, Wildform shall resolve Program Errors
in the manner provided in Exhibit A.

Date with the first payment being payable 30 days from the Effective Date, and
each subsequent payment payable within thirty (30) days of the preceding payment
and (b) $50,000 upon On2's acceptance of the Deliverables pursuant to Section
3.1 hereof; and (ii) the Payment Shares, issuable upon the 12-month anniversary

                                    ARTICLE V

                                 CONFIDENTIALITY

      5.1 Use of Confidential Information. The Receiving Party represents and
warrants to the Disclosing Party that:

            5.1.1 it will keep and maintain all Confidential Information of the
Disclosing Party in strict confidence, using such degree of care as is
appropriate to avoid unauthorized use or disclosure;

            5.1.2 it will not, directly or indirectly, disclose any Confidential
Information to any third party, except as contemplated by this Agreement or with
the Disclosing Party's prior written consent;

            5.1.3 it will not make use of any Confidential Information for its
own purposes, such as creation of a competitive product; or for the benefit of
anyone or any entity other than as contemplated by this Agreement;

            5.1.4 upon the Disclosing Party's written request, at the earlier of
the end of the Term, or receipt of notice from the Disclosing Party of a breach
by it of this Agreement or an Annex, the Receiving Party will deliver promptly
to the Disclosing Party or, at the Receiving Party's option, will destroy all
memoranda, notes, records, reports, media and other documents and materials (and
all copies thereof) regarding or including any Confidential Information which
the Receiving Party may then possess or have under its control; and

            5.1.5 it will take no action with respect to the Confidential
Information that is inconsistent with its confidential and proprietary nature.

      5.2 Exceptions to Non-Disclosure Obligations. Notwithstanding the
foregoing, the Receiving Party shall be permitted to disclose Confidential
Information without any violation of this Agreement if such disclosure is
required by law, but in such event the Receiving Party shall notify the
Disclosing Party in writing in advance of such disclosure, and provide the
Disclosing Party with copies of any related information so that the Disclosing
Party may take appropriate action to protect its Confidential Information. The
Receiving Party acknowledges that the disclosure of Confidential Information of
the Disclosing Party may cause irreparable injury to the Disclosing Party and
damages that may be difficult to ascertain. The Disclosing Party shall,
therefore, be entitled to injunctive relief upon a disclosure or threatened
disclosure of any Confidential Information of the Disclosing Party in violation
of this Agreement, in addition to such other remedies as may be available at law
or in equity. Without limitation of the foregoing, the Receiving Party shall
promptly advise the Disclosing Party in the event that the Receiving Party
learns or has reason to believe that any person or entity that has had access to
Confidential Information of the Disclosing Party through the Receiving Party has
violated or intends to violate the terms of this Agreement.

      5.3 Receiving Party's Duty of Care. Receiving Party shall protect the
Confidential Information from unauthorized use or disclosure by exercising the
same degree of care that Receiving Party uses with respect to information of its
own of a similar nature, but in no event less than reasonable care, until five
(5) years from the later of the Effective Date or the date of receipt of such
Confidential Information. Notwithstanding the prior sentence, with respect to
Receiving Party's employees, Receiving Party shall only disclose Confidential
Information to a Receiving Party employee who has a need to know such
Confidential Information for purposes of this Agreement or any customer
sublicense and is informed of the confidential nature of the Confidential
Information. The foregoing notwithstanding, each Party shall be liable for any
failure by such Party's employees, agents or representatives to comply with the
provisions of this Section 5 as fully as if such employees, agents or
representatives were a party to this Agreement.

      (c)   Payment Shares. The Payment Shares to be issued by On2 to Wildform
            hereunder: (i) are duly authorized; and (ii) when issued and

            issued, fully paid, non-assessable and not subject to preemptive
            rights; and (iii) when issued and exchanged pursuant to the terms of
            this Agreement, shall have been approved for listing on the American
            Stock Exchange (or such other trading market or exchange on which
            the Common Stock is listed or quoted for trading on the date in
            question).

      6.2 Wildform Warranties. Wildform makes the following representations and
warranties to On2.

            best of Wildform's knowledge as of the Effective Date, the
            Deliverables marked as Deliverable #2 will not infringe any
            Intellectual Property Rights held by any third party.

      (b)   Investment Representation. Wildform acknowledges that it is aware
            that the Payment Shares have not been registered under the Act.
            Wildform represents and warrants to the Buyer that such Wildform is
            acquiring the Payment Shares for investment purposes and not with a
            view to or for sale in connection with any distribution thereof or

<PAGE>

            and that there is no assurance that Buyer's business or operations
            will be successful. Wildform has considered carefully the risks
            attendant to an investment in the Payment Shares and acknowledges
            that, as a consequence of such risks, such Wildform could lose its
            entire investment in the Payment Shares. Wildform acknowledges that,
            at a reasonable time prior to the Effective Date, Buyer furnished to
            it the information specified in paragraph (b)2(ii)(A) or (B) of, and

            of, Rule 502 promulgated under Exchange Act.

      (c)   Restricted Securities. Wildform understands that the Payment Shares
            will be "restricted securities" under applicable federal securities
            laws and the rules of the Securities and Exchange Commission
            promulgated thereunder. Wildform acknowledges that it may dispose of
            the Payment Shares only pursuant to an effective registration
            statement under the Act or an exception from registration if
            available. Wildform further understands that, except as provided in
            the Registration Rights Agreement (as defined below), Buyer has no
            obligation to register the sale of the Payment Shares or take any
            other action so as to permit sales pursuant to the Act. Wildform
            further understands that applicable state securities laws may impose
            additional constraints upon the sale of securities

      6.3 No Warranty. EXCEPT AS PROVIDED IN SUBSECTIONS 6.1 AND 6.2 ABOVE, THE

this Agreement or the transactions contemplated hereby shall be instituted by a
party in a Federal or state court sitting in the jurisdiction and venue of the
other party, which shall be the exclusive jurisdiction and venue of said legal
proceedings and each party hereto waives any objection which such party may now
or hereafter have to the laying of venue of any such action, suit or proceeding,
and irrevocably submits to the jurisdiction of any such court in any such
action, suit or proceeding. Any and all service of process and any other notice
in any such action, suit or proceeding shall be effective against such party (or
the subsidiary of such party) when transmitted in accordance with Section 10.8.
Nothing contained herein shall be deemed to affect the right of any party hereto
to serve process in any manner permitted by law.

      10.9 No Implied Waivers. No delay or omission by either party to exercise

the date hereof, the Company will prepare and file with the Commission a
registration statement under the Securities Act (the "Registration Statement")
effecting the registration of the Shares. If Company, in its sole discretion,
determines that the method of disposition shall be an underwritten public
offering, Company may designate the managing underwriter of such offering,
subject to the approval of Wildform, which approval shall not be withheld
unreasonably. The Registration Statement will be filed on a form available to
the Company, with respect to the Shares. The Company will use commercially
reasonable efforts to cause such Registration Statement to become effective
prior to the 12-month anniversary of the date hereof. The Company agrees to:

            (1) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective for
the distribution period (determined pursuant to subparagraph (11) below) and as
may be necessary to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such Registration
Statement;

                                      -2-
<PAGE>

            (2) furnish to each Holder and to each underwriter such number of
copies of the Registration Statement and the prospectus included therein
(including each preliminary prospectus and each document incorporated by
reference therein to the extent then required by the rules and regulations of
the Commission) as such Persons may reasonably request in order to facilitate
the public sale or other disposition of the Registrable Securities covered by
such Registration Statement;

            (3) if applicable, use commercially reasonable efforts to register
or qualify the Registrable Securities covered by such Registration Statement
under the securities or blue sky laws of such jurisdictions as the Holder or, in
the case of an underwritten public offering, the managing underwriter, shall
reasonably request, provided that the Company will not be required to qualify
generally to transact business in any jurisdiction where it is not then required
to so qualify or to take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject;

            (4) immediately notify Holder and each underwriter, at any time when
a prospectus relating to such Registration Statement is required to be delivered
under the Securities Act, of the happening of any event as a result of which the
prospectus contained in such Registration Statement, as then in effect, includes
an untrue statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing and as promptly as
practicable amend or supplement the prospectus or take other appropriate action
so that the prospectus does not include an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
then existing;

            (5) in the case of an underwritten public offering, enter into such
customary agreements, including an underwriting agreement, and furnish, at the
request of the underwriters, such opinions of counsel, and "cold comfort"
letters from the independent accountants for the Company as are, in each case,
customary in form and substance;

            (6) make available for inspection by Holder (or its designated
representative), any underwriter participating in any distribution pursuant to
such Registration Statement, and any attorney, accountant or other agent
retained by such representative of the Holder or underwriter (the "Inspectors"),
all financial and other records, pertinent corporate documents and properties of
the Company (collectively, the "Records"), and cause the Company's officers,
directors and employees to supply all information reasonably requested by any
such Inspector in connection with such Registration Statement; provided that the
Company may require the Inspectors to conduct their investigation in a manner
that does not unreasonably disrupt the Company's operations and to execute such
reasonable confidentiality agreements as the Company may reasonably determine to
be advisable;

            (7) cause the Registrable Securities to be listed on any national
securities exchange if the Common Stock is or becomes so listed;

            (8) use commercially reasonable efforts to keep effective and
maintain for the period specified in subparagraph (11) a registration,
qualification, approval or listing obtained to cover the Registrable Securities
as may be necessary for the Holder to dispose thereof and shall from time to
time amend or supplement any prospectus used in connection therewith to the
extent necessary in order to comply with applicable law;

            (9) use commercially reasonable efforts to cause the Registrable
Securities to be registered with or approved by such other governmental agencies
or authorities as may be necessary by virtue of the business and operations of
the Company to enable the Holder to consummate the disposition of such
Registrable Securities;

                                      -3-
<PAGE>

            (10) take such other actions as are reasonably requested by the
Holder or the underwriters, if any, in order to expedite, facilitate or
consummate the disposition of such Registrable Securities; and

            (11) the period of distribution of Registrable Securities in a firm
commitment underwritten public offering shall be deemed to extend until each
underwriter has completed the distribution of all securities purchased by it
(but not more than six months) and the period of distribution of Registrable
Securities in any other registration shall be deemed to extend until the earlier
of the sale of all Registrable Securities covered thereby or eighteen months.

      Holder, upon receipt of notice from the Company of the happening of any
event of the kind described in subsection (4) of this Section 2.03, shall
forthwith discontinue disposition of the Registrable Securities until Holder's
receipt of the copies of the supplemented or amended prospectus contemplated by
subsection (4) of this Section 2.03 or until it is advised in writing by the
Company that the use of the prospectus may be resumed, and it has received
copies of any additional or supplemental filings which are incorporated by
reference in the prospectus, and, if so directed by the Company, Holder will, or
will request the managing underwriter or underwriters, if any, to, deliver to
the Company (at the Company's expense) all copies in their possession or
control, other than permanent file copies then in Holder's possession, of the
prospectus covering such Registrable Securities current at the time of receipt
of such notice; provided, however, that the Company may not require the Holder
to discontinue disposition of the Registrable Securities for more than 90 days
in any one-year period. If the Company shall give any such notice, the time
periods specified in subsection (11) of this Section 2.03 shall be extended by
the number of days during the period from and including the date of the giving
of such notice to and including the date when Holder shall have received the
copies of the supplemented or amended prospectus contemplated by subsection (4)
of this Section 2.03 hereof or the notice that they may resume use of the
prospectus.

      In connection with each registration hereunder with respect to an
underwritten public offering, the Company and Holder agrees to enter into a
written agreement with the managing underwriter or underwriters selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between
underwriters and companies of the Company's size and investment stature,
provided that such agreement shall not contain any such provision applicable to
the Company or the Holder that is inconsistent with the provisions hereof; and
further provided, that the time and place of the closing under said agreement
shall be as mutually agreed upon among the Company, the Holder and such managing
underwriter; and provided further that the Holder shall not be required to
indemnify the underwriters except with respect to information regarding the
Holder furnished in writing by or on behalf of the Holder expressly for
inclusion in any Registration Statement or prospectus relating to the
Registrable Securities, or any amendment or supplement thereto, and the
liability of the Holder shall not be greater in amount than the dollar amount of
the proceeds received by the Holder from the sale of the Registrable Securities
giving rise to such indemnification. Each the Holder shall supply to the Company
the information relating to the Holder that is required by the Securities Act
and the rules and regulations thereunder to be included in a Registration
Statement which registers Registrable Securities of the Holder and the Holder
shall execute all consents, powers of attorney, registration statements and
other documents reasonably required to be signed by the Holder in order to
effectuate the registration or disposition of Registrable Securities by the
Holder.

      Section 2.02. Expenses.

            (1) "Registration Expenses" means all expenses incident to the
Company's performance under or compliance with this Agreement, including without
limitation, all registration and filing fees, blue sky fees and expenses,
printing expenses, listing fees, fees and disbursements of counsel and

                                      -4-
<PAGE>

independent public accountants for the Company, fees of the National Association
of Securities Dealers, Inc., transfer taxes, fees of transfer agents and
registrars, costs of insurance and reasonable out-of-pocket expenses; provided,
however, that Registration Expenses shall not include any expenses incurred
directly by the Holder for legal counsel.

            (2) The Company will pay all Registration Expenses in connection
with each Registration Statement filed pursuant to this Agreement, whether or
not the Registration Statement becomes effective.

      Section 2.03. Indemnification. (1) In the event of a registration of any
Registrable Securities under the Securities Act pursuant to this Agreement, the
Company will indemnify and hold harmless Holder and each Person, if any, who
controls Holder within the meaning of the Securities Act and the Exchange Act,
against any losses, claims, damages or liabilities (including reasonable
attorneys' fees) ("Losses"), joint or several, to which Holder or such
controlling Person may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as such Losses (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement under which such
Registrable Securities were registered under the Securities Act pursuant to this
Agreement, any preliminary prospectus or final prospectus contained therein, or
any amendment or supplement thereof, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse as incurred Holder and each such controlling Person for any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such Loss or actions; provided, however, that the Company will
not be liable in any such case if and to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission so made in conformity
with information furnished by Holder or its controlling Person in writing
specifically for use in such Registration Statement or prospectus.

            (2) Holder agrees to indemnify and hold harmless the Company, its
directors, officers, employees and agents and each Person, if any, who controls
the Company within the meaning of the Securities Act or of the Exchange Act to
the same extent as the foregoing indemnity from the Company to Holder, but only
with respect to information regarding Holder furnished by or on behalf of Holder
for inclusion in any Registration Statement or prospectus relating to the
Registrable Securities, or any amendment or supplement thereto; provided,
however, that the liability of Holder shall not be greater in amount than the
dollar amount of the proceeds received by Holder from the sale of the
Registrable Securities giving rise to such indemnification.

            (3) Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to any indemnified party under this Section 2.07, unless (and only to the
extent) the indemnifying party shall have been materially prejudiced by such
failure to give notice, and such failure to give notice shall not relieve the
indemnifying party from any obligation of indemnification or contribution
arising otherwise than under this Section 2.07. In case any such action shall be
brought against any indemnified party and it shall notify the indemnifying party
of the commencement thereof, the indemnifying party shall be entitled to
participate in and, to the extent it shall wish, to assume and undertake the
defense thereof with counsel reasonably satisfactory to such indemnified party
and, after notice from the indemnifying party to such indemnified party of its
election so to assume and undertake the defense thereof, the indemnifying party
shall not be liable to such indemnified party under this Section 2.07 for any
legal expenses subsequently incurred by such indemnified party in connection
with the defense thereof; provided, however, that, (i) if the indemnifying party
has failed to assume the defense and employ counsel or (ii) if the defendants in
any such action include both the indemnified party and the indemnifying party
and counsel to the indemnified party shall have reasonably concluded that the
interests of the indemnified party conflict with the interests of the
indemnifying party, then the indemnified party shall have the right to select a
separate counsel reasonably acceptable to the indemnifying party and to assume
such legal defense and otherwise to participate in the defense of such action,
with the reasonable expenses and fees of such separate counsel and other
reasonable expenses related to such participation to be reimbursed by the
indemnifying party as incurred.

                                      -5-
<PAGE>

            (4) If the indemnification provided for in this Section 2.07 is
unavailable to the Company or the Holder or is insufficient to hold them
harmless in respect of any Losses, then each such indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Losses as between the
Company on the one hand and Holder on the other, in such proportion as is
appropriate to reflect the relative fault of the Company on the one hand and of
Holder on the other in connection with the statements or omissions which
resulted in such Losses, as well as any other relevant equitable considerations.
The relative fault of the Company on the one hand and Holder on the other shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statements of a material fact or the omission or alleged omission to
state a material fact has been made by, or relates to, information supplied by
such party, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

      No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
Person who is not guilty of such fraudulent misrepresentation.

      Section 2.08. Reports Under the Securities Act and Exchange Act. With a
view to making available to the Holder the benefits of Rule 144 promulgated
under the Securities Act and any other rule or regulation of the Commission that
may at any time permit a Holder to sell securities of the Company to the public
without registration or pursuant to a registration on Form S-3, the Company
agrees to:

      (a) Use reasonable commercial efforts to file with the SEC in a timely
manner and make and keep available all reports and other documents required of
the Company under the Securities Act and the Exchange Act so long as the Company
remains subject to such requirements and the filing and availability of such
reports and other documents is required for the applicable provisions of Rule
144; and

      (b) take such action as reasonably is necessary to enable the Holder to
