                                   ARTICLE II
                  REPRESENTATIONS AND WARRANTIES OF THE SELLERS

         To induce the Purchaser to enter into this Agreement, to purchase the
Purchased Assets and to perform its other obligations under this Agreement, the
Seller represents and warrants to the Purchaser as follows:

         2.1      VALIDITY AND EXECUTION OF AGREEMENT. The Seller has the full
legal right, capacity and power required to enter into, execute and deliver
this Agreement and each of the Ancillary Agreements to which it is a party
and to perform fully its obligations hereunder and thereunder. This Agreement
and each of the Ancillary Agreements to which it is a party have been duly
<PAGE>

executed and delivered by the Seller, and, assuming this Agreement and each of
the Ancillary Agreements constitutes a valid and binding obligation of the
Purchaser and each other party thereto, constitutes a valid and binding
obligation of the Seller, enforceable in accordance with its terms, subject to
the qualifications that enforcement of the rights and remedies created hereby is
subject to (a) bankruptcy, insolvency, reorganization, moratorium and other laws
of general application affecting the rights and remedies of creditors and (b)
general principles of equity (regardless of whether such enforcement is
considered in a proceeding in equity or at law).

         2.2      NO CONFLICT. Except as described in SCHEDULE 2.2, neither the
execution and delivery of this Agreement and each of the Ancillary Agreements by
the Seller nor the performance by the Seller of the transactions contemplated
hereby or thereby will: (a) violate, conflict with, result in the acceleration
of, or entitle any party to accelerate the maturity or the cancellation of the
performance of any obligation under, or result in the creation or imposition of
any Lien in or upon any of the properties or assets of the Seller or constitute
a default (or an event which might, with the passage of time or the giving of
notice, or both, constitute a default) under any mortgage, indenture, deed of
trust, lease, contract, loan or credit agreement, license or other instrument to
which the Seller is a party or by which it or any of its respective properties
or assets may be bound or affected; or (b) violate or conflict with any
provision of any Law or Order applicable to the Seller or the Business or
require any consent or approval of or filing or notice with any Governmental or
Regulatory Body by the Seller or the Business, as the case shall be.

         2.3      GOOD TITLE CONVEYED. The Bill of Sale endorsements,
assignments and other instruments to be executed and delivered by the Seller
to Purchaser at the Closing will be valid and binding obligations of the
Seller, enforceable in accordance with their respective terms, and will
effectively vest in Purchaser good, valid and marketable title to all the
Purchased Assets to be transferred to Purchaser pursuant to and as
contemplated by this Agreement free and clear of all Liens (other than
Permitted Liens).

         2.4      ASSETS NECESSARY TO THE BUSINESS. Except for government
permits, licenses and other consents and authorizations of any Governmental
or Regulatory Body required to be obtained by the Purchaser, the Purchaser
will have all necessary assets and rights, including rights to be conveyed
under the Ancillary Agreements, to carry on the Business in all material
respects in the same manner and to the same extent as conducted by the Seller
at the date hereof.

         2.5      FINANCIAL STATEMENTS; BOOKS AND RECORDS. (a) Schedule 2.5 sets
forth the following: (a) an unaudited balance sheet of the Seller as at June 30,
1998 and 1999 and the related unaudited statement of income, retained earnings
and cash flows for the years then ended, and (b) an unaudited balance sheet of
the Seller as at December 31, 1999 and the related unaudited statement of income
for the six months then ended. Except as set forth on Schedule 2.5(a), such
financial statements have been prepared in accordance with generally accepted
accounting principles ("GAAP") consistently applied throughout the periods
indicated. Each such balance sheet fairly presents the financial condition of
the Seller as at the respective date thereof and reflects all claims against and
all obligation, debts and liabilities of the Seller, fixed or contingent, as at
the date thereof, required to be shown thereon in accordance with GAAP, and the
related statements of income, retained earnings and cash flows fairly present
the results of operations, retained earnings and cash flows of the Seller for
the periods indicated.
<PAGE>

         (b) The Seller has made available to Parent or the Purchaser copies of
all of the Books and Records of the Seller. Except as described in SCHEDULE 2.5,
to the best knowledge of the Seller, each of the Books and Records as supplied
to Parent or the Purchaser is true, correct, complete and current in all
material respects and, as applicable, accurately reflects all actions taken by
the Seller since the date of inception of the Business, and all signatures
contained therein are the true signatures of the Persons whose signatures they
purport to be.

         2.6      NO MATERIAL ADVERSE CHANGE. Except as described in SCHEDULE
2.6, since January 1, 2000, there has been no material adverse change in the
business, operations, income or condition (financial or otherwise), assets or
properties of the Seller, nor is any such change threatened, nor has there
been any damage, destruction or loss which could reasonably be expected to
have a Material Adverse Effect on the Seller, whether or not covered by
insurance.

         2.7      TAX MATTERS. Except as described in SCHEDULE 2.7, (i)
Seller has properly and timely filed or caused to be filed all Tax Returns
required by applicable law to be filed by it and has paid all Taxes properly
due for the periods covered by such Tax Returns; (ii) all such Tax Returns
were correct and complete; (iii) there are no security interests in any of
the Purchased Assets that arose in connection with any failure (or alleged
failure) to pay any Tax (except for Liens for Taxes not yet due); and (iv)
Seller has not been a party to any tax allocation or sharing arrangement.

         2.8      LITIGATION. There are no outstanding Orders by which the
Seller, or any of the assets or properties of the Seller are bound, and,
except as described in SCHEDULE 2.8, there is no Action or Proceeding pending
or, to the knowledge of the Seller, threatened (whether or not the defense
thereof or liabilities in respect thereof are covered by insurance) against
or affecting the Seller or any of the assets or properties of the Seller,
nor, to the knowledge of the Seller, are there any facts which are likely to
give rise to any such Action or Proceeding which if adversely decided, would
have a Material Adverse Effect on the Seller.

         2.9      CONTRACTS AND OTHER AGREEMENTS. SCHEDULE 2.9 sets forth the
Material Contracts to which the Seller is a party or to which any of the assets
or properties of the Seller, is bound or subject. The Seller has delivered true
and complete copies of all of the Material Contracts to Parent or the Purchaser.
All of the Material Contracts are valid, subsisting, in full force and effect
and binding upon the Seller and, to the knowledge of the Seller, the other
parties thereto in accordance with their terms, subject to the qualifications
that enforcement of the rights and remedies created thereby is subject to (i)
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting the rights and remedies of creditors and (ii) general
principles of equity (regardless of whether such enforcement is considered in a
proceeding in equity or at law). The Seller has satisfied in full or provided
for all of its liabilities and obligations under such Material Contracts
requiring performance prior to the date hereof in all material respects, and is
not in default under any of them, nor, to the knowledge of the Seller, does any
condition exist that with notice or lapse of time or both would constitute such
a default. To the knowledge of the Seller, no other party to any such Material
Contract is in default thereunder, nor does any condition exist that with notice
or lapse of time or both would constitute such a default. Except as set forth
on SCHEDULE 2.9 under the heading "Required Consents/Contracts," no approval or
consent of any Person is needed for any of the Material Contracts to continue to
be in full force and effect. Assuming receipt of all consents set forth

<PAGE>

under the heading "Required Consents/Contracts" in SCHEDULE 2.9, all of the
Seller's rights under such Material Contracts will be in full force and effect
following consummation of the transactions contemplated by this Agreement.

         2.10     TRANSACTIONS WITH AFFILIATES. Except as set forth on SCHEDULE
2.10, no Affiliate of the Seller has: (a) borrowed money from or loaned money to
the Seller which remains outstanding; (b) had any contractual or other claim,
express or implied, of any kind whatsoever against the Seller; (c) had any
interest in any property or assets used by the Seller; (d) engaged in any other
transaction with the Seller; or (e) owned, directly or indirectly, any interest
in (except not more than five percent (5%) stockholdings for investment purposes
in securities of publicly held and traded companies), or served as a director,
employee or consultant of or otherwise received remuneration from, any Person
which is, or has engaged in business as, a competitor, lessor, lessee, customer
or supplier of the Seller.

         2.11     OPERATIONS. Except as expressly authorized by this
Agreement or as set forth on SCHEDULE 2.11, since January 1, 2000, the Seller
has not:

                  (a) merged with or into or consolidated with any other Person,

Rights shall continue to be in full force and effect and enforceable by the
Purchaser following the transactions contemplated by this Agreement. All
Intellectual Property Rights purported to be owned by the Seller held by any
employee, director or consultant have been validly assigned to the Seller. The
Seller's Intellectual Property Rights are sufficient to carry on the Business as
presently conducted. The Seller has exclusive ownership of or license to use all
Intellectual Property Rights identified in SCHEDULE 2.16 or has obtained any
licenses, releases or assignments reasonably necessary to use all third parties'
Intellectual Property Rights in works embodied in its products. To the knowledge
of the Seller, the business activities or products of the Business do not

programming processes, software and other information required for or incident
to its products or its business as presently conducted or contemplated. The
Seller has taken all reasonable measures to protect and preserve the security
and confidentiality of its Intellectual Property Rights. The Purchaser
understands that no employees or consultants of the Seller involved in the
design, review, evaluation or development of products or Intellectual Property
Rights have executed nondisclosure or deeds or assignment of inventions
agreements sufficient to protect the confidentiality of the Seller's
Intellectual Property Rights and to vest in the Seller exclusive ownership of
such Intellectual Property Rights. All material trade secrets and other material
confidential information of the Seller are presently valid and protectable and
are not part of the public domain or knowledge, nor, have they been used,
divulged or appropriated for the benefit of any Person other than the Seller or
otherwise to the detriment of the Seller or the Business. No employee or
consultant of the Seller has used any material trade secrets or other material
confidential information of any other Person in the course of their work for the
Business.
                  (c) The Seller is the exclusive owner of all right, title and
interest in its Intellectual Property Rights as purported to be owned by the
Seller, and such Intellectual Property Rights are valid and in full force and
effect. No university, government agency (whether federal or state) or other
organization has sponsored research and development conducted by the Seller or
has any claim of right to or ownership of or other encumbrance upon the
Intellectual Property Rights of the Seller. The Seller is not aware of any
infringement by others of its copyrights or other Intellectual Property Rights
in any of its products, technology or services, or any violation of the
confidentiality of any of its proprietary information. The Seller is not making
unlawful use of any confidential information or trade secrets of any past or
present employees of the Seller.

                  (d) The Purchaser understands that no key employees, including
all developers (contract or otherwise) of or to the Seller, have executed and
delivered to and in favor of the Seller agreements regarding the protection of
confidential and proprietary information and the assignment to the Seller of
Intellectual Property Rights arising from the services performed for the Seller
by such persons.

Except as set forth on SCHEDULE 2.17 under the heading "Required
Consents/Permits," no material Permit is required to be obtained by the Seller
in connection with the properties or assets used in the Business. The Company
has not received any notice of any claim of revocation of any such Permit. The
Seller has no knowledge of any event which would be likely to give rise to such
a claim.

         2.18 COMPLIANCE WITH LAWS. The Seller (a) is in compliance with all,
and not in violation of any, and has not received any claim or notice that it is
not in compliance in any material respect with, or that it is in violation in
any material respect of, any Law or Order to which the Seller or any of the
assets or properties of the Seller (including the use and occupancy thereof) are
subject and (b) has not failed in any material respect to obtain or to adhere to
the requirements of any Permit necessary in connection with its assets or
properties.

         2.19 BROKERS. All negotiations relating to this Agreement and the
transactions contemplated hereby have been carried out by the Seller directly
with the Purchaser, without the intervention of any other Person on behalf of
the Seller in such manner as to give rise to any valid claim by any Person
against the Seller or the Purchaser for a finder's fee, brokerage commission or
similar payment.

         2.20 ACQUISITION OF ON2.COM SHARES.

                  (a) The Seller represents and warrants that the Share
Consideration is being acquired for its own account, with no intention of
transferring or assigning any participation or any interest therein, and without
a view to the distribution of any portion thereof, except in accordance with the
Securities Act. The Seller will not sell, assign, transfer or encumber any of
such shares unless (i) a registration statement under the Securities Act with
respect thereto is in effect and the prospectus included therein meets the
requirements of Section 10 of the Securities Act or (ii) the Purchaser has
received a written opinion of its counsel that, after an investigation of the
relevant facts, such counsel is of the opinion that such proposed sale,
assignment, transfer or encumbering does not require registration under the
Securities Act; PROVIDED, that the Seller may transfer the Share Consideration
to its Shareholders in accordance with their holdings of the Company pursuant to
a plan of complete liquidation.

                  (b) The Seller understands that (i) the Share Consideration is
not being registered under Securities Act and must be held indefinitely unless
the Share Consideration is subsequently registered thereunder or any exemption
from such registration is available and therefore (ii) the Seller may be
required to bear the economic risk of its investment in the Share Consideration
for an indefinite period of time, (iii) the Share Consideration is not being
registered under the Securities Act in part on the ground that the issuance
thereof is exempt under Section 4(2) of the Securities Act as a transaction by
an issuer not involving any public offering and (iv) the Purchaser's reliance on
such exemption is predicated in part on the foregoing representation and
warranty of the Seller.
<PAGE>

                  (c) The Seller understands that the Purchaser will have an
appropriate stop order placed on its stock records indicating the existence of
the terms of this Agreement, and that each certificate representing the Share
Consideration, shall bear the following or a substantially similar legend:

         "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED
OR ENCUMBERED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT, OR UNLESS
THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT THAT SUCH
SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY
REQUIREMENTS OF SAID ACT."

                  or in certificates delivered pursuant to this Agreement; and

                           (ii) any and all Damages arising out of or in any way

<PAGE>

                           (iii) any Cost incurred and actually paid by the

Shareholders from and against;

                           (i) any and all Damages incurred by the Seller or any
                  Shareholder arising out of, relating to or based upon any
                  inaccuracy in, or breach of, any of the representations or
                  warranties, covenants or agreements of Parent or the Purchaser
                  contained in or incorporated into this Agreement or in
                  certificates delivered pursuant to this Agreement;

                           (ii) any and all Damages arising out of the
                  Purchaser's failure to perform the Assumed Obligations that
                  arise after the Closing Date; and

                           (iii) any Cost incurred by the Seller or any
                  Shareholder in connection with the enforcement of this
                  Agreement.

The rights of the Seller and the Shareholders to be indemnified hereunder shall
not be limited or affected by any investigation conducted or notice or knowledge
obtained by or on behalf of such persons.

         7.4 METHOD OF ASSERTING CLAIMS. The party making a claim under this
Article 7 is referred to as the "Indemnified Party" and the party against whom
such claims are asserted under this Article 7 is referred to as the
"Indemnifying Party". All claims by any Indemnified Party under this Article 7
shall be asserted and resolved as follows:

                  (a) Whenever an Indemnified Party becomes aware of a claim for
which an Indemnifying Party would be liable to an Indemnified Party hereunder,
the Indemnified Party shall with reasonable promptness notify in writing the
Indemnifying Party of such claim, identifying the representation or warranty on
which such claim is based, the basis for such claim or demand, and the amount or
the estimated amount thereof to the extent then determinable (which estimate
shall not be conclusive of the final amount of such claim and demand; the "Claim
Notice"); PROVIDED, that any failure to give a Claim Notice will not be deemed a
waiver of any rights of the Indemnified Party except to the extent the rights of
the Indemnifying Party are actually prejudiced by such failure. If the basis of
such claim is a claim or demand by a third party, the Indemnifying Party, upon
request of the Indemnified Party, shall retain counsel (who shall be reasonably
acceptable to the Indemnified Party) to represent the Indemnified Party and
shall pay the reasonable fees and disbursements of such counsel with regard
thereto; PROVIDED, that any Indemnified Party is hereby authorized prior to the
date on which it receives written notice from the Indemnifying Party designating
such counsel, to retain counsel, whose fees and expenses shall be at the expense
of the Indemnifying Party, to file any motion, answer or other pleading and take
such other action which it reasonably shall deem necessary to protect its
interests or those of the Indemnifying Party until the date on which the
Indemnified Party
<PAGE>

receives such notice from the Indemnifying Party. After the Indemnifying Party
shall retain such counsel, the Indemnified Party shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party unless (x) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(y) representation of both parties by the same counsel would be inappropriate
due to actual or potential differing interests between them. The Indemnifying
Party shall not, in connection with any proceedings or related proceedings in
the same jurisdiction, be liable for the fees and expenses of more than one such
firm for the Indemnified Party (except to the extent the Indemnified Party
retained counsel to protect its (or the Indemnifying Party's) rights prior to
the selection of counsel by the Indemnifying Party). If requested by the
Indemnifying Party, the Indemnified Party agrees to cooperate with the
Indemnifying Party and its counsel in contesting any claim or demand which the
Indemnifying Party defends. A claim or demand may not be settled by either party
without the prior written consent of the other party (which consent shall not be
unreasonably withheld) unless, as part of such settlement, the Indemnified Party
shall receive a full and unconditional release reasonably satisfactory to such
Indemnified Party.

                  (b) Whenever any Indemnified Party shall have a claim against
any Indemnifying Party hereunder which does not involve a claim or demand being
asserted against or sought to be collected from it by a third party, the
Indemnified Party shall send a Claim Notice with respect to such claim to the
Indemnifying Party.

                  (c) After delivery of a Claim Notice, so long as any right to
indemnification exists pursuant to this Article 7, the affected parties each
agree to retain all Books and Records related to such Claim Notice. In each
instance, the Indemnified Party shall have the right to be kept fully informed
by the Indemnifying Party and its legal counsel with respect to any legal
proceedings. Any information or documents made available to any party hereunder
and designated as confidential by the party providing such information or
documents and which is not otherwise generally available to the public and not
already within the knowledge of the party to whom the information is provided
(unless otherwise covered by the confidentiality provisions of any other
agreement among the parties hereto, or any of them), and except as may be
required by applicable law, shall not be disclosed to any third Person (except
for the representatives of the party being provided with the information, in
which event the party being provided with the information shall request its
representatives not to disclose any of such information which it has agreed
hereunder to keep confidential).

         7.5 LIMITATIONS ON THE SELLER'S OBLIGATIONS. Notwithstanding the
provisions of Section 7.2, no claim for indemnification under Section 7.2 may be
made (a) unless the aggregate amount of Damages or Taxes (aggregating all claims
for indemnification under such Section) exceeds Fifty Thousand dollars
($50,000), and then only to the extent that this threshold is exceeded, claims
may be made from first dollar from and after such threshold has been exceeded.
In no event shall the Seller be liable for claims in excess of the value of the
Escrowed Shares.

         7.6 GENERAL PROVISIONS. The following general provisions shall apply to
any claim for indemnification under this Article 7:
<PAGE>

                  (a) The amount of any claim subject to indemnification shall
be determined after taking into account the present value of any tax benefits
(net of tax detriments) accruing to the Indemnified Party or any Affiliate as a
result of such claim.

                  (b) Except as otherwise set forth in this Section 7.6(b), with
respect to any breach, violation or nonfulfillment of or default in the
performance of any representation, warranty or covenant of this Agreement for
which a right to claim indemnification is provided in this Article 7, after the
Closing a claim or an action under and pursuant to the terms, conditions and
limitations of this Article 7 shall be the sole and exclusive right and remedy
of the Purchaser and the Seller, and neither the Purchaser nor the Seller shall
have any other claim, cause of action, right, or remedy for such breach,
violation, non-fulfillment or default against the other based upon this
Agreement, any provision of any securities or other statute, law, rule or
regulation or based upon any other cause of action arising at law or in equity;
PROVIDED, that if for any reason a court of competent jurisdiction shall refuse
to enforce this provision, and shall permit the Purchaser or the Seller to
assert any action based other than upon the right to claim indemnification as
provided in this Article 7, the Purchaser and the Seller agree that the amount
of such other claim shall be subject to and limited by the provisions of this
Article 7. The provisions of this Section 7.6(b) shall not preclude the
prosecution of any action or proceeding based on fraud that, if found to exist,
would be sufficient to give rise to the right of rescission with respect to the
transactions contemplated by this Agreement.

                  (c) The obligations of the Seller shall be satisfied as
provided in the Escrow Agreement.

         7.7 CHARACTER OF INDEMNITY PAYMENTS. All amounts paid pursuant to
Article VII shall be treated by such parties as adjustments to the consideration
paid with respect to the Purchased Assets sold by the Seller.


                                  ARTICLE VIII

and

                  (b) by the Purchaser, on the one hand, or by the Seller, on
the other hand, by written notice to the other party hereto, if the Closing
shall not have occurred on or prior to the close of business on April 3, 2000
(unless such delay has been caused by a breach of this Agreement by the party
seeking such termination); and

                  (c) by the Purchaser or by the Seller, if any Judgment shall
have been enacted, entered, promulgated or enforced which prohibits or enjoins
the consummation of the sale and purchase of the Share Consideration and such
Judgment is or shall have become final and nonappealable.
<PAGE>

         8.2 SURVIVAL AFTER TERMINATION. If this Agreement is terminated
pursuant to Section 8.1, (a) this Agreement shall become null and void and of no
further force and effect, except for the provisions of Article 4 relating to the
obligation to keep confidential certain information and (b) there shall be no
liability on the part of the Seller or the Purchaser or their respective
Affiliates.
