proposed to be conducted. Neither the execution nor delivery of this Agreement
or the Related Agreements, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as presently
proposed, will, to the Company's knowledge, conflict with or result in a breach
of the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any employee is now obligated. The
Company does not believe it is or will be necessary to utilize any inventions,
trade secrets or proprietary information of any of its employees made prior to

                (a) The Company is not in violation or default of any term of
its Certificate of Incorporation or Bylaws, or of any material term of any

<PAGE>

with this Agreement, and the Related Agreements, and the issuance and sale of
the Shares pursuant hereto and the Conversion Shares pursuant to the Certificate
of Incorporation, will not, with or without the passage of time or giving of
notice, result in any such material violation, or be in conflict with or
constitute a default under any such material term, or result in the creation of
any mortgage, pledge, lien, encumbrance or charge upon any of the properties or
assets of the Company or the suspension, revocation, impairment, forfeiture or
nonrenewal of any permit, license, authorization or approval applicable to the
Company, its business or operations or any of its assets or properties.

                (b) The Company has avoided every condition, and has not
performed any act, the occurrence of which would result in the Company's loss of

Effect.

           3.13 Litigation. There is no action, suit, proceeding or
investigation pending or to the Company's knowledge currently threatened against
the Company or its officers that questions the validity of this Agreement, or
the Related Agreements or the right of the Company to enter into any of such
agreements, or to consummate the transactions contemplated hereby or thereby, or
which might have, either individually or in the aggregate, Material Adverse
Effect or result in a change in the current equity ownership of the Company, nor
is the Company aware that there is any basis for any of the foregoing. The
foregoing includes, without limitation, actions pending or threatened (or any
basis therefor known to the Company) involving the prior employment of any of
the Company's employees, their use in connection with the Company's business of
any information or techniques allegedly proprietary to any of their former
employers, or their obligations under any agreements with prior employers. The
Company is not a party or subject to the provisions of any order, writ,
injunction, judgment or decree of any court or government agency or
instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or which the Company intends to initiate.

employment, social security and wage withholding taxes) and installments of
estimated taxes, assessments, deficiencies, levies, imports, duties, license
fees, registration fees, withholdings, or other similar charges of every kind,
character or description imposed by any governmental or quasi-governmental
authorities, and any interest, penalties or additions to tax imposed thereon or
in connection therewith (collectively, "Taxes") due as of the Closing Date. The
Company has timely filed or has obtained presently effective extensions with
respect to all Federal, state, county, local and foreign tax returns
(collectively, "Tax Returns") that the Company is required to file. The Tax
Returns are true and correct and all taxes shown thereon to be due have been
timely paid. No penalties or other charges are or will become due with respect
to any such Tax Returns as the result of the late filing thereof. The Company
has either paid or established in the Financial Statements adequate reserves for
the payment of all such Taxes due or claimed to be due by any taxing authority
in connection with any such Tax Returns. None of the Company's federal income
tax returns have been audited by the Internal Revenue Service, and no
controversy with respect to taxes of any type is pending or, to the knowledge of
the Company, threatened. The Company has withheld or collected from each payment
made to its employees the amount of all

                                        9

<PAGE>

taxes required to be withheld or collected therefrom (including, but not limited
to, federal income taxes and Federal Insurance Contribution Act taxes) and has
paid all such amounts to the appropriate taxing authorities when due. The
Company's net operating losses for federal income tax purposes, as set forth in
the Financial Statements, are not subject to any limitations imposed by Section
382 of the Internal Revenue Code of 1986 as amended (the "Code"), and
consummation of the transactions contemplated by this Agreement of by any other
agreement, understanding or commitment, contingent or otherwise, to which the
Company is a party or by which it is otherwise bound will not have the effect of
limiting the Company's ability to use such net operating losses in full to
offset such taxable income.

           3.15 Employees. The Company has no collective bargaining agreements
with any of its employees. There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company. The
Company is not delinquent in payments to any of its employees for any wages,
salaries, commissions, bonuses or other direct compensation for any services
performed by them to date or amounts required to be reimbursed to such employees
and upon any termination of the employment of any such employees. Schedule 3.15
sets forth a true, correct and complete list of all employment, severance,
non-competition, deferred compensation and similar arrangements between the
Company and all officers, employees and consultants of the Company and all such
arrangements with former officers, employees and consultants of the Company
pursuant to which the Company is obligated to make any payments or provide any
benefits. To the Company's knowledge, no employee of the Company, nor any
consultant with whom the Company has contracted, is in violation of any term of
any employment contract, proprietary information agreement or any other
agreement relating to the right of any such individual to be employed by, or to
contract with, the Company because of the nature of the business to be conducted
by the Company; and to the Company's knowledge the continued employment by the
Company of its present employees, and the performance of the Company's contracts
with its independent contractors, will not result in any such violation. The
Company has not received any notice alleging that any such violation has
occurred. No employee of the Company has been granted the right to continued
employment by the Company or to any material compensation following termination
of employment with the Company. The Company is not aware that any officer or key
employee, or that any group of key employees, intends to terminate his, her or
their employment with the Company, nor does the Company have a present intention
to terminate the employment of any officer, key employee or group of key
employees.

Agreements and Market Stand-off Agreements.

           (a)  Each former and current employee, officer and consultant of the
Company has executed an Assignment of Inventions, Non-Disclosure and
Non-Competition Agreement in the form of Exhibit H attached hereto. No current
employee, officer or consultant of the Company has excluded works or inventions
made prior to his or her employment with the Company from his or her assignment
of inventions pursuant to such employee, officer or consultant's Assignment of
Inventions, Non-Disclosure and Non-Competition Agreement.

           (b)  Each key employee of the Company and each holder of options to
purchase equity and debt convertible into equity has executed a market stand-off

           3.17 Obligations of Management. Each officer of the Company is
currently devoting one hundred percent (100%) of his or her business time to the
conduct of the business of the Company. The Company is not aware that any
officer or key employee of the Company is planning to work less than full time
at the Company in the future. To the Company's knowledge, no officer or key
employee plans to work for a competing enterprise, whether or not such officer
or key employee is or will be compensated by such enterprise.

and no registrations or declarations are required to be filed in connection with
the execution and delivery of this Agreement and the issuance of the Shares and
the Conversion Shares, except such as has been duly and validly obtained or

licenses and any similar authority necessary for the conduct of its business as
now being conducted by it, the lack of which could materially and adversely
affect the business, properties, prospects or financial condition of the Company
and believes it can obtain, without undue burden or expense, any similar
authority for the conduct of its business as planned to be conducted.

           3.20 Environmental and Safety Laws. To the Company's knowledge, the
Company is not in violation of any applicable statute, law or regulation
relating to the environment or occupational health and safety, and to its
knowledge, no material expenditures are or will be required in order to comply

reasonable expenses incurred on behalf of the Company and (c) for other standard

the Company, or any members of their immediate families, are indebted to the
Company or have any direct or indirect ownership interest in any firm or
corporation with which the Company is affiliated or with which the Company has a

(other than such contracts as relate to any such person's ownership of capital
stock or other securities of the Company). Except as may be disclosed in the

Adverse Effect on such assets, liabilities, financial condition, operations or

               (b)  Any resignation or termination of any officer or key

               (k)  Any sale, assignment or transfer of any patents, trademarks,
copyrights, trade secrets or other intangible assets;

               (l)  Any change in any material agreement to which the Company is
a party or by which it is bound which has had or would reasonably be expected to
have a Material Adverse Effect;

               (m)  Any other event or condition of any character that, either
individually or cumulatively, has had or would reasonably be expected to have a
Material Adverse Effect; or

               (n)  Any arrangement or commitment by the Company to do any of
the acts described in subsection (a) through (m) above.

         3.10  Title to Properties and Assets; Liens, Etc. The Company has good
and marketable title to its properties and assets, including the properties and
assets reflected in the most recent balance sheet included in the Financial
Statements, and good title to its leasehold estates, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than (a) those
resulting from taxes which have not yet become delinquent, (b) minor liens and
encumbrances which do not materially detract from the value of the property
subject thereto or materially impair the operations of the Company and (c) those
that have otherwise arisen in the ordinary course of business. All facilities,
machinery, equipment, fixtures, vehicles and other properties owned, leased or
used by the Company are in good operating condition and repair and are
reasonably fit and usable for the purposes for which they are being used. The
Company is in compliance with all material terms of each lease to which it is a
party or is otherwise bound.

          3.11 Patents and Trademarks.

               (a)  The Company owns or possesses sufficient legal rights to all
patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information and other proprietary rights and processes necessary for
its business as now conducted and as presently proposed to be conducted, without
any known infringement of the rights of others. There are no outstanding
options, licenses or agreements of any kind relating to the foregoing, nor is
the Company bound by or a party to any options, licenses or agreements of any
kind with respect to the patents, trademarks, service marks, trade names,
copyrights, trade secrets, licenses, information and other proprietary rights
and processes of any other person or entity other than such licenses or
agreements arising from the purchase of "off the shelf" or standard products,
and those arising in the ordinary course of business.

               (b)  The Company is not aware of any allegations that the Company
has violated or, by conducting its business as presently proposed, would violate
any of the

                                       7

<PAGE>

patents, trademarks, service marks, trade names, copyrights or trade secrets or
other proprietary rights of any other person or entity.

               (c)  The Company is not aware that any of its employees is
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with their duties to
the Company or that would conflict with the Company's business as presently
proposed to be conducted. Neither the execution nor delivery of this Agreement
or the Related Agreements, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as presently
proposed, will, to the Company's knowledge, conflict with or result in a breach
of the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any employee is now obligated. The
Company does not believe it is or will be necessary to utilize any inventions,
trade secrets or proprietary information of any of its employees made prior to
their employment by the Company, except for inventions, trade secrets or
proprietary information that have been assigned to the Company.

               (d)  The Company is not aware of any claims by any other person
or entity contesting the validity, enforceability, use or ownership of any of
the patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information and other proprietary rights and processes necessary for
its business as now conducted and as presently proposed to be conducted. The
Company is not aware of any infringement or misappropriation by any other person
or entity with respect to any of the patents, trademarks, service marks, trade
names, copyrights, trade secrets, licenses, information and other proprietary
rights and processes necessary for its business as now conducted and as
presently proposed to be conducted.

          3.12 Compliance with Other Instruments.

               (a)  The Company is not in violation or default of any term of
its Certificate of Incorporation or Bylaws, or of any material term of any
mortgage, indenture, contract, agreement, instrument or contract to which it is
party or by which it is bound or of any judgment, decree, order, or writ. The
execution, delivery, and performance of and compliance with this Agreement, and
the Related Agreements, and the issuance and sale of the Shares pursuant hereto
and the Conversion Shares pursuant to the Certificate of Incorporation, will
not, with or without the passage of time or giving of notice, result in any such
material violation, or be in conflict with or constitute a default under any
such material term, or result in the creation of any mortgage, pledge, lien,
encumbrance or charge upon any of the properties or assets of the Company or the
suspension, revocation, impairment, forfeiture or nonrenewal of any permit,
license, authorization or approval applicable to the Company, its business or
operations or any of its assets or properties.

               (b)  The Company has avoided every condition, and has not
performed any act, the occurrence of which would result in the Company's loss of
any right granted under any license, distribution agreement or other agreement
to which the Company is a party if such loss would have a Material Adverse
Effect.

                                        8

<PAGE>

          3.13 Litigation. There is no action, suit, proceeding or investigation
pending or to the Company's knowledge currently threatened against the Company
or its officers that questions the validity of this Agreement, or the Related
Agreements or the right of the Company to enter into any of such agreements, or
to consummate the transactions contemplated hereby or thereby, or which might
have, either individually or in the aggregate, Material Adverse Effect or result
in a change in the current equity ownership of the Company, nor is the Company
aware that there is any basis for any of the foregoing. The foregoing includes,
without limitation, actions pending or threatened (or any basis therefor known
to the Company) involving the prior employment of any of the Company's
employees, their use in connection with the Company's business of any
information or techniques allegedly proprietary to any of their former
employers, or their obligations under any agreements with prior employers. The
Company is not a party or subject to the provisions of any order, writ,
injunction, judgment or decree of any court or government agency or
instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or which the Company intends to initiate.

          3.14 Tax Returns and Payments. The Company has paid all federal,
state, local and foreign taxes (including, without limitation, income, profit,
franchise, sales, use, real property, personal property, ad valorem, excise,
employment, social security and wage withholding taxes) and installments of
estimated taxes, assessments, deficiencies, levies, imports, duties, license
fees, registration fees, withholdings, or other similar charges of every kind,
character or description imposed by any governmental or quasi-governmental
authorities, and any interest, penalties or additions to tax imposed thereon or
in connection therewith (collectively, "Taxes") due as of the Closing Date. The
Company has timely filed or has obtained presently effective extensions with
respect to all Federal, state, county, local and foreign tax returns
(collectively, "Tax Returns") that the Company is required to file. The Tax
Returns are true and correct and all taxes shown thereon to be due have been
timely paid. No penalties or other charges are or will become due with respect
to any such Tax Returns as the result of the late filing thereof. The Company
has either paid or established in the Financial Statements adequate reserves for
the payment of all such Taxes due or claimed to be due by any taxing authority
in connection with any such Tax Returns. None of the Company's federal income
tax returns have been audited by the Internal Revenue Service, and no
controversy with respect to taxes of any type is pending or, to the knowledge of
the Company, threatened. The Company has withheld or collected from each payment
made to its employees the amount of all taxes required to be withheld or
collected therefrom (including, but not limited to, federal income taxes and
Federal Insurance Contribution Act taxes) and has paid all such amounts to the
appropriate taxing authorities when due. The Company's net operating losses for
federal income tax purposes, as set forth in the Financial Statements, are not
subject to any limitations imposed by Section 382 of the Internal Revenue Code
of 1986 as amended (the "Code"), and consummation of the transactions
contemplated by this Agreement of by any other agreement, understanding or
commitment, contingent or otherwise, to which the Company is a party or by which
it is otherwise bound will not have the effect of limiting the Company's ability
to use such net operating losses in full to offset such taxable income.

          3.15 Employees. The Company has no collective bargaining agreements
with any of its employees. There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company. The
Company is not delinquent in payments to any of its employees for any wages,
salaries, commissions, bonuses or other direct

                                       9

<PAGE>

compensation for any services performed by them to date or amounts required to
be reimbursed to such employees and upon any termination of the employment of
any such employees. Schedule 3.15 sets forth a true, correct and complete list
of all employment, severance, non-competition, deferred compensation and similar
arrangements between the Company and all officers, employees and consultants of
the Company and all such arrangements with former officers, employees and
consultants of the Company pursuant to which the Company is obligated to make

registering the Shares or the Conversion Shares or any shares of its Common

foregoing, the Company acknowledges that in order for the Asset Sale to qualify
as a tax-free transaction under Section 368(a)(1)(C) of the Internal Revenue
Code of 1986, as amended, the Purchaser is required to, and is planning to and
