corporation duly organized, validly existing and in good standing under the laws
of the State of California and has all requisite corporate power and authority
to own its properties and to carry on its business as currently conducted. The
Company is duly licensed or qualified to do business as a foreign corporation in
each jurisdiction where the failure to do so would constitute a Material Adverse
Change (as defined in Section 3.6 below).

               3.2 Authorization. The Company has all necessary corporate power
and has taken or will take prior to the Closing all necessary corporate action
required for the due authorization, execution, delivery and performance by the

Agreements") and any other agreements or instruments to be executed by the
Company in connection herewith or therewith and the consummation of the
transactions contemplated herein or therein, and for the due authorization,
issuance and delivery of the Preferred Shares. The issuance of the Preferred
Shares does not require any further corporate action and is not and will not,
except as provided in the Related Agreements, be subject to any preemptive
right, right of first refusal or the like. This Agreement, the Related
Agreements and the other agreements and instruments to be executed by the
Company in connection herewith or therewith will each, when executed by the
Company, be a valid and binding obligation of the Company enforceable in
accordance with its respective terms, except as such enforceability may be
limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or
other similar federal or state laws affecting the rights of creditors, (ii)
rules of law governing specific performance, injunctive relief or other
equitable remedies (whether considered in a proceeding at law or in equity) or
(iii) indemnification provisions to the extent limited by statutes, judicial
decisions or public policy considerations.

               3.3 Government Approvals. No consent, approval, license or
authorization of, or designation, declaration or filing with, any court or
governmental authority is or will be required on the part of the Company in
connection with the execution, delivery and performance by the Company of this
Agreement, any of the Related Agreements and any other agreements or instruments
executed by the Company in connection herewith or therewith, or in connection
with the issuance of the Preferred Shares the failure of which would cause a
Material Adverse Change except for (i) those which have already been made or
granted, (ii) those required to be made pursuant to (A) Section 25102(f) of the
California Corporate Securities Law of 1968, as amended, and the rules
thereunder (the "Law"), or (b) the securities laws of any other state in which

Company as of the Closing Date and immediately prior to the Closing Date is
10,000,000 shares of Common Stock and 2,400,000 shares of Preferred Stock, all
of which have been designated Series A Preferred Stock (the "Series A Shares").
There are issued and outstanding 2,000,000 shares of the Company's Common Stock.

conversion rights and agreements for the purchase or acquisition from the
Company of any shares of its capital stock is set forth in Section 3.4 of the
Disclosure Schedule), except that the Company has (i) reserved 1,165,000 shares
of its Common Stock for issuance under the Company's 1998 Stock Option Plan to
its employees, consultants, directors or officers and (ii) reserved 2,316,279

of the Company to Common Stock of the Company. Except as set forth in Section

agreement or understanding between any persons or entities which affects or
relates to the voting or giving of written consents with respect to any
securities or by any director of the Company, except as provided for in the
Related Agreements.

               3.5 Subsidiaries. The Company has neither any subsidiaries nor
any joint venture relationships nor any investment or other equity or
equity-like interest in, or any outstanding loan or advance to or from, any
person, including, without limitation, any officer, director or shareholder of
the Company except travel, meal and similar reimbursement obligations created in
the ordinary course of business.

               3.6 Financial Information. The Company has attached hereto as
Schedule 3.6 to the Disclosure Schedule the unaudited financial statements of
the Company for the period ended December 15, 1998 (the "Unaudited Financial
Statements"). The Unaudited Financial Statements are in accordance with the
books and records of the Company and present fairly in accordance with generally
accepted accounting principles applied on a basis consistent with prior periods
the financial condition and results of operations of the Company as of the dates
and for the periods shown, subject to year end adjustments which will not be
material, and subject to the absence of footnotes otherwise required. The

none of the business, financial condition, operations, property or affairs of
the Company has been materially adversely affected by any occurrence or
development, individually or in the aggregate, whether or not insured against.
"Material Adverse Change" means any change in, or effect on, the business,
conditions, affairs or operations of the Company (including all subsidiaries, if
any) or in any of its properties or assets, or any material impairment of the
right or ability of the Company (including all subsidiaries, if any) to carry on
its business as now conducted or as proposed to be conducted in the future (the
"Business") (x) that is, or is reasonably likely to be, materially adverse to
the results of the operations or the financial condition of the Company (or any
subsidiary) or the Business or (y) that requires or is reasonably likely to
require the expenditure of Ten Thousand Dollars ($10,000) or more, individually
or in the aggregate.

               3.7 Events Subsequent to the Date of the Financial Statements.
Since November 30, 1998, the Company has not (i) issued any capital interest,

under contracts entered into in the ordinary course of business except travel,

into any commitment (contingent or otherwise) to do any of the foregoing.

               3.8 Litigation . There is no litigation or governmental
proceeding pending or, to the knowledge of the Company, threatened against the
Company or its predecessor or affecting any of the Company's properties or
assets, or against any officer, key employee or shareholder of the Company or
its predecessor in his capacity as such, nor, to the knowledge of the Company,
has there occurred any event which questions the validity of this Agreement and
the Related Agreements or any action taken or to be taken in connection
herewith, including in each case, without limitation, actions pending or, to the
knowledge of the Company, threatened, involving the prior employment of any of
the Company's employees, the use in connection with the Business of any
information or techniques allegedly proprietary to any of its former employees,
or their obligations under any agreements with prior employers. There is no
governmental investigation pending or, to the best knowledge of the Company,
threatened against the Company or its predecessor or affecting any of the
Company's properties or assets, or against any officer, key employee or
shareholder of the Company or its predecessor in his capacity as such. Neither
the Company, nor, to the best of its knowledge, any officer, key employee or
shareholder of the Company or its predecessor, in his capacity as such, is in
default with respect to any order, writ, injunction, decree, ruling or decision
of any court, commission, board or other government agency which may materially
and adversely affect the Business or assets of the Company. There is no action,
suit, proceeding or investigation by the Company currently pending or which the
Company currently intends to initiate.

               3.9 Compliance with Laws and Other Instruments. The Company is as
of the Closing Date in compliance with all of the provisions of this Agreement
and of its Restated Articles and in all material respects with the provisions of
(i) each judgment, decree and judicial order by which it is bound or to which it
or any of its properties are subject and to its knowledge, each statute, rule or
regulation applicable to the Company and (ii) each mortgage, indenture, lease,
license, other agreement or instrument by which it is bound or to which it or
any of its properties are subject. Neither the execution, delivery or
performance of this Agreement and the Related Agreements, nor the offer,
issuance, sale or delivery of the Preferred Shares in accordance with the
provisions of this Agreement and the Restated Articles, with or without the
giving of notice or passage of time, or both, will violate, or result in any
breach of, or constitute a default under, or result in the imposition of any
encumbrance in any material respect upon any asset of the Company pursuant to
any provision of the Company's Restated Articles, or, to the best knowledge of
the Company, any statute, rule or regulation applicable to the Company, or any
judgment, decree, judicial order, mortgage, indenture, lease, license or other
agreement or instrument by which the Company is bound or to which the Company or
any of its properties are subject, or, to the best knowledge of the Company,
will cause the Company to lose the benefit of any material right or privilege it
currently enjoys or cause any person who is expected to normally do business
with the Company to discontinue to do so on substantially the same basis.

<PAGE>   6

               3.10 Taxes. The Company has filed all tax returns (including
statements of estimated taxes owed) required to be filed within the applicable
periods for such filings and has paid all taxes required to be paid (other than
those contested in good faith for which adequate reserves have been
established), and has established adequate reserves (net of estimated tax
payments already made) for the payment of all taxes payable in respect of the
period subsequent to the last periods covered by such returns. There is no
pending dispute with any taxing authority relating to any of such returns and
the Company has not received notice of any proposed liability for any tax to be
imposed upon the properties or assets of the Company. No deficiencies for any
tax are currently assessed against the Company, and no tax returns of the
Company have ever been audited, and, to the actual knowledge of the Company,
there is no such audit pending or threatened. There is no tax lien, whether
imposed by any federal, state or local taxing authority, outstanding against the
assets, properties or business of the Company or its predecessor, except such
liens for taxes not yet due and payable as may accrue in the ordinary course of
business and for which the Company has established reasonable reserves and as
would not, in any case, constitute a Material Adverse Change. For the purposes
of this Agreement, the term "tax" shall include all federal, state and local
taxes, including income, franchise, property, sales, withholding, payroll and
employment taxes.

               3.11 Real Property.

                      (a) Schedule 3.11 to the Disclosure Schedule sets forth
the addresses and uses of all real property that the Company owns, leases or
subleases, and any material lien or encumbrance on any such owned real property
or the Company's leasehold interest therein, specifying in the case of each such
lease or sublease, the name of the lessor or sublessor, as the case may be, and
the lease term. Copies of all leases have been provided to special counsel to
the Purchasers.

                      (b) The Company has good and marketable title to, and owns
free and clear of all liens and encumbrances, all property listed as owned by
the Company on Schedule 3.11, and, to the knowledge of the Company, there is no
material violation of any law, regulation or ordinance (including without
limitation laws, regulations or ordinances relating to zoning, environmental,
city planning or similar matters) relating to any real property owned, leased or
subleased by the Company.

                      (c) There are no defaults by the Company or, to the
knowledge of the Company, by any other party thereto, which might curtail in any
material respect the current use of the Company's property listed on Schedule
3.11. The performance by the Company of this Agreement and the Related
Agreements will not result in the termination of, or in any increase of any
amounts payable under, any lease listed on Schedule 3.11.

               3.12 Personal Property. Except for property sold or otherwise
disposed of in the ordinary course of business since September 30, 1998, the
Company owns free and clear of any liens or encumbrances, all of the personal
property reflected as owned by the Company in the balance sheet contained in the
Unaudited Financial Statements, and all other material items of personal
property acquired by the Company through the date hereof. All material items of
such personal property are in good operating condition, normal wear and tear
excepted.

               3.13 Patents, Trademarks, etc.

                      (a) Set forth on Schedule 3.13 is a list of all patents,
patent rights, patent applications, trademarks, trademark applications, service
marks, service mark applications, trade names and registered copyrights, and all
applications for such that are in the process of being prepared, owned by or
registered in the

<PAGE>   7

name of the Company, or of which the Company is a licensor or licensee or in
which the Company has any right, except licenses to commercially available
software legally in the possession of the Company and having a purchase price of
less than $2,000 per copy. The Company owns and possesses sufficient right,
title and interest in and to, or has obtained licenses to use, all software,
software tools, works of authorship, copyrights, know-how, trade secrets and
registered trade names (and to its best knowledge owns and possesses sufficient
right, title and interest in and to, or has obtained licenses to use, all
patentable inventions and common law tradenames) used in or necessary for the
conduct of its Business, free and clear of all liabilities, charges, liens,
pledges, mortgages, restrictions, adverse claims, security interests, rights of
others and encumbrances (including, without limitation, distribution rights)
(all of which are referred to as "Proprietary Rights"), except, in each case,
where such failure would not constitute a Material Adverse Change. The foregoing
representation as it relates to Third Party Technology (as defined herein) is
limited to the Company's interest pursuant to the Third Party Licenses (as
defined herein), all of which are, to the best knowledge of the Company, valid
and enforceable and in full force and effect and which grant the Company such
rights to Third Party Technology as are employed in or necessary to the
Business. Schedule 3.13 contains (i) an accurate and complete description of all
registered and unregistered trademarks and trade names owned or licensed to the
Business, and a list of all licenses and other agreements relating thereto and
(ii) a list of all licenses and other agreements with third parties (the "Third
Party Licenses") relating to any software, copyrights, works of authorship,
technology, know-how or processes that the Company is licensed or otherwise
authorized by such third parties to use, market, distribute or incorporate into
products distributed by the Company, except licenses to commercially available
software legally in the possession of the Company and having a purchase price of
less than $2,000 per copy (such software, technology, know-how and processes are
collectively referred to as the "Third Party Technology"). All of the copyrights
in any of the Company Products (including but not limited to any works of
authorship incorporated in or distributed with such products) used by the
Company in connection with the Business are owned by the Company, or licensed to
the Company, and are in full force and effect, and the consummation of the
transactions contemplated hereby will not alter or impair any such rights. No
claims have been asserted against the Company, and to the best knowledge of the
Company (actual knowledge in the case of common law trademarks and tradenames
and patents) there are no claims which are reasonably likely to be asserted
against the Company or which have been asserted against others by any person
challenging the Company's use or distribution of any trademarks, tradenames,
copyrights, works of authorship, trade secrets, software, technology, know-how
or processes utilized by the Company (including, without limitation, the Third
Party Technology) or challenging or questioning the validity or effectiveness of
any license or agreement relating thereto (including, without limitation, the
Third Party Licenses). The use of any trademarks, tradenames, copyrights, works
of authorship, software, technology, know-how or processes by the Company in its
Business does not infringe on the rights of, constitute misappropriation of, or
in any way involve unfair competition with respect to, any proprietary
information or intangible property right of any third person or entity,
including, without limitation, any patent, trade secret, copyright, trademark or
tradename; provided, however, that such representation is made only to the
Company's actual knowledge with respect to common law trademarks and tradenames,
technology, patent or similar intangible property right where infringement is
possible without wrongful taking and where no readily accessible and exhaustive
search process would serve to have warned the Company.

                      (b) To the best knowledge of the Company, all designs,
drawings, specifications, source code, object code, documentation, flow charts
and diagrams incorporated in any of the Company's Proprietary Rights (the
"Company Components") constitute original creations of and were written,
developed and created solely and exclusively by employees of the Company
without the assistance of any third party or entity or were created by, or with
the assistance of, third parties who assigned ownership of or licensed their
rights to the Company in valid and enforceable agreements. The Company has at
all times used commercially

<PAGE>   8

reasonable efforts to treat its trade secrets as confidential and has not
disclosed or otherwise dealt with such items in such a manner as to cause the
loss of such trade secrets by release into the public domain.

                      (c) To the best knowledge of the Company, no employee of
the Company is in violation of any term of any employment contract, patent
disclosure agreement, confidentiality agreement or any other contract or
agreement relating to the relationship of any such employee with the Company or,
to the best knowledge of the Company, any other party because of the nature of
the Business.

               3.14 Agreements of Directors, Officers and Employees. To the best
knowledge of the Company, no director, officer or employee of or consultant to
the Company is in violation of any restrictive covenants contained in any
employment contract, non-competition agreement, non-disclosure agreement, patent
disclosure or assignment agreement or other contract or agreement relating to
the right of any such director, officer, employee or consultant to be employed
or engaged by the Company because of the nature of the Business, or relating to
the use of trade secrets or proprietary information of others.

               3.15 Governmental Approvals. The Company has all the permits,
licenses, orders, franchises and other rights and privileges of all federal,
state, local or foreign governmental or regulatory bodies necessary for the
Company to conduct its business as presently conducted, except, in each case,
where such failure would not constitute a Material Adverse Change. All such
permits, licenses, orders, franchises and other rights and privileges are in
full force and effect except, in each case, where such failure would not
constitute a Material Adverse Change and, to the best knowledge of the Company,
no suspension or cancellation of any of them is threatened, and none of such
permits, licenses, orders, franchises or other rights and privileges will be
adversely affected by the Closing.

               3.16 Contracts and Commitments. All contracts, obligations or
commitments to which the Company is a party or by which it is bound (including
purchase orders to the Company or placed by the Company) which involve
obligations of, or payments to, the Company in excess of Five Thousand Dollars
($5,000) and all agreements between the Company and its officers, directors,
consultants and employees are set forth on the list attached hereto as Schedule
3.17 (the "Contracts"), copies of which have been delivered to special counsel
to the Purchasers. All of the Contracts are valid and binding obligations of the
Company and in full force and effect in all material respects and enforceable by
the Company in accordance with their respective terms in all material respects,
except as such enforceability may be limited by (i) applicable bankruptcy,
insolvency, reorganization, moratorium or other similar federal or state laws
affecting the rights of creditors, (ii) rules of law governing specific
performance, injunctive relief or other equitable remedies (whether considered
in a proceeding at law or in equity) or (iii) indemnification provisions to the
extent limited by statutes, judicial decisions or public policy considerations.
The Company is not in material default under any of such Contracts. To the best
knowledge of the Company, no other party to any of the Contracts is in material
default thereunder.

               3.17 Securities Act. The Company has complied and will comply
with all applicable federal or state securities laws in connection with the
issuance and sale of the Preferred Shares, and, in reliance on the
representations and warranties of the Purchasers in Section 4 hereof, the
Company hereby asserts that (i) the offer, sale and issuance of the Preferred
Shares in conformity with the terms of this Agreement will not result in a
violation of the requirements of Section 5 of the Securities Act of 1933, as
amended (the "Act"), or the qualification or registration requirements of the
Law or other applicable blue sky laws and (ii) neither the Company nor, to the
best knowledge of the Company, anyone acting on its behalf has offered any of
the Preferred Shares, or similar securities, or solicited any offers to purchase
any of such securities, in such a manner as to bring the issuance and sale of
the Preferred Shares under the registration provisions of the Act.

<PAGE>   9

               3.18 Registration Rights. The Company has not granted or agreed
to grant any rights relating to registration of its capital stock under the Act
or state securities laws other than those contained in this Agreement or the
Related Agreements.

               3.19 Insurance Coverage. Schedule 3.20 to the Disclosure Schedule
contains an accurate summary of the insurance policies currently maintained by
the Company. There are currently no claims in excess of Ten Thousand Dollars
($10,000) in the aggregate pending against the Company under any insurance
policies currently in effect and covering the property, business or employees of
the Company, and all premiums due and payable with respect to the policies
maintained by the Company have been paid to date.

               3.20 Employee Matters. Except as set forth in Schedule 3.21
hereof, the Company does not have in effect, and its assets are not subject to,
any employment agreements, consulting agreements, deferred compensation, pension
or retirement agreements or arrangements, bonus, incentive or profit-sharing
plans or arrangements, or labor or collective bargaining agreements, written or
oral. The Company is in compliance, and its predecessor was in compliance, in
all material respects, with all applicable laws and regulations relating to
labor, employment, fair employment practices, terms and conditions of
employment, and wages and hours. Each officer, director, employee and consultant
of the Company has executed an agreement regarding confidentiality and
proprietary information, the form of which is attached hereto as Exhibit C.
Except as set forth in Schedule 3.21 hereof, the Company is not aware that any
officer, director or employee 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 in any material way with the use of his or her best efforts to
promote the interests of the Company, conflict with the Company's Business or
prevent any such employee from assigning inventions to the Company. Neither the
execution nor delivery of this Agreement or the Related Agreements, nor the
carrying on 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 of such employees is now obligated. Furthermore, the
Company does not believe that it will be necessary for the Company to utilize
any inventions of any of its employees made prior to their employment by the
Company except in cases where obtaining a license to do such is expected to be
routine and license fees are not material to the Business.

               3.21 Labor Agreements and Actions. The Company is not bound by or
subject to (and none of its assets or properties are bound by or subject to) any
contract, commitment or arrangement with any labor union, and no labor union has
requested or, to the knowledge of the Company, has sought to represent any of
the employees, representatives or agents of the Company. There is no strike or
other labor dispute involving the Company pending, or to the knowledge of the
Company threatened, which could constitute a Material Adverse Change, nor is the
Company aware of any labor organization activity involving its employees. The
Company is not aware that any officer or key employee, or that any group of key
employees, intends to terminate his, her or its employment with the Company, nor
does the Company have a current intention to terminate the employment of any of
the foregoing. Subject to general principles related to wrongful termination of
employees, the employment of each officer and employee of the Company is
terminable at the will of the Company.

               3.22 No Brokers or Finders. No person has or will have, as a
result of the transactions contemplated by this Agreement, any right, interest
or claim against or upon the Company for any commission, fee or other
compensation as a finder or broker because of any act or omission by the
Company. -

               3.23 Transactions with Affiliates. There are no loans, leases or
other continuing transactions involving more than $10,000 (in the aggregate)
annually between the Company, any officer or director of the Company or any
person owning five percent (5%) or more of the voting power of the Company on
the one hand and any respective family member or affiliate of such officer,
director or shareholder on the other hand.

               3.24 Assumptions, Guarantees, etc. of Indebtedness of Other
Persons. The Company has not assumed, guaranteed, endorsed or otherwise become
directly or contingently liable on or for any indebtedness of any other person,
except guarantees by endorsement of negotiable instruments for deposit or
collection or similar transactions in the ordinary course of business.

               3.25 Disclosures. Neither this Agreement, any Schedule or Exhibit
to this Agreement, the Related Agreements, the Unaudited Financial Statements,
nor any other agreement, document or written statement made by the Company and
furnished by the Company to the Purchasers or the Purchasers' special counsel in
connection with the transactions contemplated hereby, contains any untrue
statement of material fact or, when taken as a whole, omits to state any
material fact necessary to make the statements contained herein or therein not
misleading. There is no fact known to the Company that has not been disclosed
herein or in any other agreement, document or written statement furnished by the
Company to the Purchasers or their special counsel in connection with the
transactions contemplated hereby which is specific to the Company, as opposed to
the industry in which the Company operates, and which materially adversely
affects or is reasonably likely to materially and adversely affect the business,
properties, assets or financial condition of the Company.

        4.     Representations and Warranties of Purchasers and Restrictions on
               Transfer Imposed by the Securities Act.

               4.1 Representations and Warranties by the Purchasers. Each of the
Purchasers, severally and not jointly, represents and warrants to the Company as
follows:

                      (a) Investment Intent. This Agreement is made with each
Purchaser in reliance upon such Purchaser's representations to the Company,
evidenced by such Purchaser's execution of this Agreement, that such Purchaser
is acquiring the Preferred Shares and the Common Stock issuable upon conversion
of the Preferred Shares (collectively the "Securities") for investment for such
Purchaser's own account and not with a view to, or for resale in connection
with, any distribution or public offering thereof within the meaning of the Act
and the Law (or other applicable blue sky laws). Each Purchaser has the full
right, power and authority to enter into and perform this Agreement and the
Related Agreements, and this Agreement and the Related Agreements constitute
valid and binding obligations upon it enforceable in accordance with their
terms, except as such enforceability may be limited by (i) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar federal or
state laws affecting the rights of creditors, (ii) rules of law governing
specific performance, injunctive relief or other equitable remedies (whether
considered in a proceeding at law or in equity) or (iii) indemnification
provisions to the extent limited by statutes, judicial decisions or public
policy considerations.

                      (b) Shares Not Registered . Each Purchaser understands and
acknowledges that the offering of the Preferred Shares pursuant to this
Agreement will not be registered under the Act or qualified under the Law (or
other applicable blue sky laws) on the grounds that the offering and sale of
securities contemplated by this Agreement are exempt from registration under the
Securities Act and exempt from qualification pursuant to the applicable
provisions of the Law (and the relevant provisions of other applicable blue sky
laws), and that the Company's reliance upon such exemptions is predicated upon
such Purchaser's

<PAGE>   11

representations set forth in this Agreement. Each Purchaser acknowledges and
understands that the Securities must be held indefinitely unless the Securities
are subsequently registered under the Act and qualified under the Law (or other
applicable blue sky laws) or an exemption from such registration and such
qualification is available.

                      (c) No Transfer . Each Purchaser covenants that in no
event will it dispose of any of the Securities (other than in conjunction with
an effective registration statement for the Securities under the Act) unless and
until (i) such Purchaser shall have notified the Company of the proposed
disposition and shall have furnished the Company with a statement of the
circumstances surrounding the proposed disposition and (ii) if reasonably
requested by the Company, such Purchaser shall have furnished the Company with
an opinion of counsel reasonably satisfactory in form and substance to the
Company to the effect that (X) such disposition will not require registration
under the Act and (y) appropriate action necessary for compliance with the Act,
the Law and any other applicable state, local or foreign law has been taken. It
is agreed that the Company will not require opinions of counsel for transactions
by a Purchaser made pursuant to Rule 144.

                      (d) Permitted Transfers. Notwithstanding the provisions of
subsection (b) above, no registration statement or opinion of counsel shall be
necessary for a transfer by such Purchaser, if it is a partnership, to a partner
of such partnership or a former partner of such partnership who leaves such
partnership after the date hereof, or to the estate of any such partner or
former partner or the transfer by gift, will or intestate succession of any
partner to his spouse or lineal descendants or ancestors, if the transferee
agrees in writing to be bound by the terms of this Agreement and the Related
Agreements to the same extent as if he were an original Purchaser hereunder
provided that the Company shall receive written notice of such transfer within
thirty (30) days of its completion.

                      (e) Knowledge and Experience. Each Purchaser (i) has such
knowledge and experience in financial and business matters as to be capable of
evaluating the merits and risks of such Purchaser's prospective investment in
the Securities, (ii) has the ability to bear the economic risks of such
Purchaser's prospective investment, (iii) has been furnished with and has had
access to such information as such Purchaser has considered necessary to make a
determination as to the purchase of the Securities together with such additional
information as is necessary to verify the accuracy of the information supplied,
(iv) has had all questions which have been asked by such Purchaser
satisfactorily answered by the Company and (v) has not been offered the
Securities by any form of advertisement, article, notice or other communication
published in any newspaper, magazine, or similar media or broadcast over
television or radio, or any seminar or meeting whose attendees have been invited
by any such media.

                      (f) Accredited Investor . Each Purchaser is an "accredited
investor" within the meaning of Rule 501 promulgated by the Securities and
Exchange Commission ("SEC") under the Act.

                      (g) Authorization. All action on the part of each of the
Purchaser's partners, board of directors, and shareholders, as applicable,
necessary for the authorization, execution, delivery and performance of this
Agreement and the Related Agreements by each Purchaser, the purchase of and
payment for the Preferred Shares and the performance of all of each Purchaser's
obligations hereunder and under the Related Agreements has been taken or will be
taken prior to the Closing. This Agreement and the Related Agreements, when
executed and delivered by each Purchaser, shall constitute valid and binding
obligations of the Purchasers, enforceable in accordance with their terms,
subject to laws of general application relating to bankruptcy, insolvency and
the relief of debtors and rules of law governing specific performance,
injunctive relief or other

<PAGE>   12

equitable remedies; provided, however, that the Purchaser makes no
representation as to the enforceability of the indemnification provisions
contained in the Rights Agreement.

                      (h) Holding Requirements. Each Purchaser understands that
if the Company does not (i) register its Common Stock with the SEC pursuant to
Section 12 of the Securities Exchange Act of 1934, as amended ("Exchange Act"),
(ii) become subject to Section 15(d) of the Exchange Act, (iii) supply
information pursuant to Rule 15c2-11 thereunder or (iv) have a registration
statement covering the Securities (or a filing pursuant to the exemption from
registration under Regulation A of the Act covering the Securities) under the
Securities Act in effect when it desires to sell the Securities, such Purchaser
may be required to hold the Securities for an indeterminate period. Each
Purchaser also understands that any sale of the Securities that might be made by
such Purchaser in reliance upon Rule 144 under the Act may be made only in
limited amounts in accordance with the terms and conditions of that rule.

               4.2 Legends. Each certificate representing the Securities shall
be endorsed with the following legends:

                      (a) Federal Legend. THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), AND ARE "RESTRICTED SECURITIES" AS DEFINED IN RULE 144
PROMULGATED UNDER THE ACT. THE SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE OR
OTHERWISE DISTRIBUTED EXCEPT (i) IN CONJUNCTION WITH AN EFFECTIVE REGISTRATION
STATEMENT FOR THE SHARES UNDER THE ACT OR (ii) IN COMPLIANCE WITH RULE 144, OR
(iii) PURSUANT TO AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY, THAT SUCH
REGISTRATION OR COMPLIANCE IS NOT REQUIRED AS TO SAID SALE, OFFER OR
DISTRIBUTION.

                      (b) Other Legends. Any other legends required by the Law
or other applicable state blue sky laws. The Company need not register a
transfer of legended Securities, and may also instruct its transfer agent not to
register the transfer of the Securities, unless the conditions specified in each
of the foregoing legends are satisfied.

                      Removal of Legend and Transfer Restrictions. Any legend
endorsed on a certificate pursuant to subsection 4.2(a) and the stop transfer
instructions with respect to such legend Securities shall be removed, and the
Company shall issue a certificate without such legend to the holder of such
Securities if such Securities are registered under the Act and a prospectus
meeting the requirements of Section 10 of the Act is available or if such holder
satisfies the requirements of Rule 144(k) and, where reasonably deemed necessary
by the Company, the holder of the Securities provides the Company with an
opinion of counsel for such holder, reasonably satisfactory to the Company, to
the effect that (i) such holder meets the requirements of Rule 144(k) or (ii) a
public sale, transfer or assignment of such Securities may be made without
registration.

               4.4 Rule 144. Each Purchaser is aware of the adoption of Rule 144
by the SEC promulgated under the Act, which permits limited public resales of
securities acquired in a nonpublic offering, subject to the satisfaction of
certain conditions. Each Purchaser understands that under Rule 144, the
conditions include, among other things, the availability of certain current
public information about the issuer and the resale occurring not less than one
(1) year after the party has purchased and paid for the securities to be sold.
