<PAGE>   4

amended, and the rules thereunder, other applicable state securities laws and
Regulation D of the Securities Act of 1933, as amended (the "Securities Act").

        2.7 Litigation. There is no action, suit, proceeding or investigation
pending or, to the Company's knowledge, currently threatened against the Company
that questions the validity of the Agreements or the right of the Company to
enter into them, or to consummate the transactions contemplated hereby or
thereby, or that might result, either individually or in the aggregate, in any
material adverse changes in the assets, condition or affairs of the Company,
financially or otherwise, or any change in the current equity ownership of the
Company, nor is the Company aware that there is any basis for the foregoing. The
foregoing includes, without limitation, actions, suits, proceedings or
investigations pending or threatened 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.

        2.8 Patents and Trademarks. The Company owns or possesses sufficient
legal rights to all patents, trademarks, service marks, trade names, domain
names, copyrights, trade secrets, licenses, information and proprietary rights
and processes necessary for its business as now conducted and as proposed to be
conducted without any conflict with, or infringement of, the rights of others,
which conflict or infringement would have a material adverse effect on the
assets, condition or affairs of the Company, financially or otherwise. 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, proprietary
rights and processes of any other person or entity. The Company has not received
any communications alleging that the Company has violated or, by conducting its
business as proposed, would violate any of the patents, trademarks, service
marks, trade names, copyrights, trade secrets or other proprietary rights or
processes of any other person or entity. 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
the use of such employee's best efforts to promote the interest of the Company
or that would conflict with the Company's business as proposed to be conducted.
Neither the execution or delivery of this Agreement, nor the carrying on of the
Company's business by the employees of the Company, nor the conduct of the
Company's business as 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 such
employee is now obligated. The Company does not believe it is or will be
necessary

                                      -4-
<PAGE>   5

to use any inventions of any of its employees (or persons it currently intends
to hire) made prior to their employment by the Company.

        2.9 Compliance with Other Instruments.

                (a) The Company is not in violation or default of any provisions
of its Restated Certificate or Bylaws or of any instrument, judgment, order,
writ, decree or contract to which it is a party or by which it is bound, or of
any provision of federal or state statute, rule or regulation applicable to the
Company which would have a material adverse effect on the assets, condition or
affairs of the Company, financially or otherwise. The execution, delivery and
performance of the Agreements and the consummation of the transactions
contemplated hereby or thereby will not result in any such violation or be in
conflict with or constitute, with or without the passage of time and giving of
notice, either a default under any such provision, instrument, judgment, order,
writ, decree or contract or an event which results in the creation of any lien,
charge or encumbrance upon any assets of the Company or the suspension,
revocation, impairment, forfeiture or nonrenewal of any material permit,
license, authorization or approval applicable to the Company, its business or
operations or 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
which would have a material adverse effect on the assets, condition or affairs
of the Company, financially or otherwise.

        2.10 Agreements; Action.

secret or other proprietary right to or from the Company, or (iii) the grant of

advances to any person, or (iv) sold, exchanged or otherwise disposed of any of
its assets or rights, other than the sale of its inventory in the ordinary
course of business.

and proposed transactions involving the same person or entity (including persons

the Stock and all information which the Company believes is reasonably necessary

"Business Plan"). The representations and warranties of the Company contained in
this Agreement and the exhibits attached hereto and in any certificate furnished
or to be furnished to Purchasers at the Closing do not contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements contained herein or therein not misleading in light of
the circumstances under which they were made. To the extent the Business Plan
was prepared by management of the Company, the Business Plan and the financial

and the Company reasonably believes there is a reasonable basis for such
projections.

indirectly, to any of its officers or directors or to their respective spouses
or children, in any amount whatsoever other than in connection with expenses or

percent of the outstanding capital stock of) any publicly traded companies that
may compete with the Company. To the Company's knowledge, none of the Company's

3. Representations and Warranties of the Purchasers. Each Purchaser hereby
represents and warrants to the Company that:

        3.1 Authorization. The Agreements, when executed and delivered by the
Purchaser, will constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with their terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and any other laws of general application affecting enforcement of
creditors' rights generally, and as limited by laws relating to the availability
of a specific performance, injunctive relief, or other equitable remedies, or
(b) to the extent the indemnification provisions contained in the Investors
Rights Agreement may be limited by applicable federal or state securities laws.

        3.2 Purchase Entirely for Own Account. This Agreement is made with the
Purchaser in reliance upon the Purchaser's representation to the Company, which
by the Purchaser's execution of this Agreement, the Purchaser hereby confirms,
that the Securities to be acquired by the Purchaser will be acquired for
investment for the Purchaser's own account, not as a nominee or agent, and not
with a view to the resale or distribution of any part thereof, and that the
Purchaser has no present intention of selling, granting any participation in, or
otherwise distributing the same. By executing this Agreement, the Purchaser
further represents that the Purchaser does not presently have any contract,
undertaking, agreement or arrangement with any person to sell, transfer or grant
participation to such person or to any third person, with respect to any of the
Securities. The Purchaser represents that it has full power and authority to
enter into this Agreement. The Purchaser has not been formed for the specific
purpose of acquiring the Securities.

        3.3 Disclosure of Information. The Purchaser has had an opportunity to
discuss the Company's business, management, financial affairs and the terms and
conditions of the offering of the Stock with the Company's management and has
had an opportunity to review the Company's facilities. The Purchaser understands
that such discussions, as well as the written information issued by the Company,
were intended to describe the aspects of the Company's business which it
believes to be material. The foregoing, however, does not limit or modify the
representations and warranties of the Company in Section 2 of this Agreement or
the right of the Purchaser to rely thereon.

        3.4 Restricted Securities. The Purchaser understands that the Securities
have not been, and will not be, registered under the Securities Act, by reason
of a specific exemption from the registration provisions of the Securities Act
which depends upon, among other things, the bona fide nature of the investment
intent and the accuracy of the Purchaser's

                                      -9-
<PAGE>   10

representations as expressed herein. The Purchaser understands that the
Securities are "restricted securities" under applicable U.S. federal and state
securities laws and that, pursuant to these laws, the Purchaser must hold the
Securities indefinitely unless they are registered with the Securities and
Exchange Commission and qualified by state authorities, or an exemption from
such registration and qualification requirements is available. The Purchaser
acknowledges that the Company has no obligation to register or qualify the
Securities for resale, except as set forth in the Investors Rights Agreement.
The Purchaser further acknowledges that if an exemption from registration or
qualification is available, it may be conditioned on various requirements
including, but not limited to, the time and manner of sale, the holding period
for the Securities, and on requirements relating to the Company which are
outside of the Purchaser's control, and which the Company is under no obligation
and may not be able to satisfy.

        3.5 No Public Market. The Purchaser understands that no public market
now exists for any of the securities issued by the Company, and that the Company
has made no assurances that a public market will ever exist for the Securities.

        3.6 Legends. The Purchaser understands that the Securities and any
securities issued in respect of or exchange for the Securities, may bear one or
all of the following legends:

                (a) "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR
        INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
        DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED
        WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN
        OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
        REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933."

                (b) Any legend required by the Blue Sky laws of any state to the
extent such laws are applicable to the shares represented by the certificate so
legended.

        3.7 Accredited Investor. The Purchaser is an "accredited investor" as
defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

        3.8 Foreign Investors. If the Purchaser is not a United States person
(as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as
amended), such Purchaser hereby represents that it has satisfied itself as to
the full observance of the laws of its jurisdiction in connection with any
invitation to subscribe for the Stock or any use of this Agreement, including
(a) the legal requirements within its jurisdiction for the purchase of the
Stock, (b) any foreign exchange restrictions applicable to such purchase, (c)
any governmental or other consents that may need to be obtained, and (d) the
income tax and other tax consequences, if any, that may be relevant to the
purchase, holding, redemption,

                                      -10-
<PAGE>   11

sale, or transfer of the Stock. Such Purchaser's subscription and payment for
and continued beneficial ownership of the Stock, will not violate any applicable
securities or other laws of the Purchaser's jurisdiction.

4. Conditions of the Purchasers' Obligations at Closing. The obligations of each
Purchaser to the Company under this Agreement are subject to the fulfillment, on
or before the Closing, of each of the following conditions, unless otherwise

affairs of the Company, financially or otherwise, or any change in the current
equity ownership of the Company, nor is the Company aware that there is any
basis for the foregoing. The foregoing includes, without limitation, actions,
suits, proceedings or investigations pending or threatened 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

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, proprietary
rights and processes of any other person or entity. The Company has not received

business as proposed, would violate any of the patents, trademarks, service
marks, trade names, copyrights, trade secrets or other proprietary rights or
processes of any other person or entity. 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
the use of such employee's best efforts to promote the interest of the Company
or that would conflict with the Company's business as proposed to be conducted.
Neither the execution or delivery of this Agreement, nor the carrying on of the
Company's business by the employees of the Company, nor the conduct of the
Company's business as proposed, will, to the Company's knowledge, conflict with

to the Company which would have a material adverse effect on the assets,
condition or affairs of the Company, financially or otherwise. The execution,
delivery and performance of the Agreements and the consummation of the
transactions contemplated hereby or thereby will not result in any such
violation or be in conflict with or constitute, with or without the passage of
time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company or the suspension, revocation, impairment, forfeiture or nonrenewal of
any material permit, license, authorization or approval applicable to the
Company, its business or operations or 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
which would have a material adverse effect on the assets, condition or affairs
of the Company, financially or otherwise.

        3. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS. Each Purchaser
hereby severally represents and warrants to the Company that:

               3.1 AUTHORIZATION. The Agreements, when executed and delivered by
the Purchaser, will constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with their terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and any other laws of general application affecting enforcement of
creditors' rights generally, and as limited by laws relating to the availability
of a specific performance, injunctive relief, or other equitable remedies, or
(b) to the extent the indemnification provisions contained in the Investors
Rights Agreement may be limited by applicable federal or state securities laws.

               3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made
with the Purchaser in reliance upon the Purchaser's representation to the
Company, which by the Purchaser's execution of this Agreement, the Purchaser
hereby confirms, that the Securities to be

                                      -9-
<PAGE>   10

acquired by the Purchaser will be acquired for investment for the Purchaser's
own account, not as a nominee or agent, and not with a view to the resale or
distribution of any part thereof, and that the Purchaser has no present
intention of selling, granting any participation in, or otherwise distributing
the same. By executing this Agreement, the Purchaser further represents that the
Purchaser does not presently have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participation to such
person or to any third person, with respect to any of the Securities. The
Purchaser represents that it has full power and authority to enter into this
Agreement. The Purchaser has not been formed for the specific purpose of
acquiring the Securities.

               3.3 DISCLOSURE OF INFORMATION. The Purchaser has had an
opportunity to discuss the Company's business, management, financial affairs and
the terms and conditions of the offering of the Stock with the Company's
management and has had an opportunity to review the Company's facilities. The
Purchaser understands that such discussions, as well as the written information
issued by the Company, were intended to describe the aspects of the Company's
business which it believes to be material. The foregoing, however, does not
limit or modify the representations and warranties of the Company in Section 2
of this Agreement or the right of the Purchaser to rely thereon.

               3.4 RESTRICTED SECURITIES. The Purchaser understands that the
Securities have not been, and will not be, registered under the Securities Act,
by reason of a specific exemption from the registration provisions of the
Securities Act which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of the Purchaser's representations as
expressed herein. The Purchaser understands that the Securities are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, the Purchaser must hold the Securities indefinitely
unless they are registered with the Securities and Exchange Commission and
qualified by state authorities, or an exemption from such registration and
qualification requirements is available. The Purchaser acknowledges that the
Company has no obligation to register or qualify the Securities for resale,
except as set forth in the Investors Rights Agreement. The Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Securities,
and on requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

               3.5 NO PUBLIC MARKET. The Purchaser understands that no public
market now exists for any of the securities issued by the Company, and that the
Company has made no assurances that a public market will ever exist for the
Securities.

               3.6 LEGENDS. The Purchaser understands that the Securities and
any securities issued in respect of or exchange for the Securities, may bear one
or all of the following legends:

                      (a) "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT
        BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED
        FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE

        DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED
        WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN
        OPINION OF COUNSEL IN A FORM REASONABLY SATISFACTORY TO THE COMPANY THAT
        SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933."

                      (b) Any legend required by the Blue Sky laws of any state

person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986,
as amended), such Purchaser hereby represents that it has satisfied itself as to
the full observance of the laws of its jurisdiction in connection with any
invitation to subscribe for the Stock or any use of this Agreement, including
(a) the legal requirements within its jurisdiction for the purchase of the
Stock, (b) any foreign exchange restrictions applicable to such purchase, (c)
any governmental or other consents that may need to be obtained, and (d) the
income tax and other tax consequences, if any, that may be relevant to the
purchase, holding, redemption, sale, or transfer of the Stock. Such Purchaser's
subscription and payment for and continued beneficial ownership of the Stock,
will not violate any applicable securities or other laws of the Purchaser's
jurisdiction.
