              ---------

amount equal to the Required Payment by the Investor.

          3.2 Conversion. Any outstanding principal and interest on the Note
              ----------

authorized sufficient shares of Common Stock for such conversion, without the
payment of any additional consideration by the Investor (i) at any time at the
sole option of the Investor, or (ii) automatically simultaneously with the
consummation of an equity offering by the Company where the gross proceeds to
the Company from such equity offering are at least Ten Million Dollars
($10,000,000), with the proceeds of the Note included in such calculation of
gross proceeds of such equity offering all in accordance with the provisions of
Section 2 of the Note.

     4.   Other Terms.
          -----------

          4.1 Security. To secure all indebtedness, liabilities, and obligations
              --------
of Company of any nature whatsoever which Investor may now or hereafter have,
own or hold, an which are now or hereafter owing to Investor pursuant to the
Note (the "Liabilities"), the Company shall execute in favor of the Investor the
Security Agreement, in the form attached hereto as Exhibit B, together with all
                                                   ---------

or maintain the perfection of the Investor's security interest thereunder.

          4.2 Agreements Regarding Interest and Other Charges. The Investor and
              -----------------------------------------------
the Company hereby agree that the only charge imposed or to be imposed by the
Investor upon the Company for the use of money is and will be the interest
required under the Note, which interest will be at the rates which are or will
be expressed in simple interest terms in the Note as of the date of such Note.
The Company hereby acknowledges and agrees that the Investor has not imposed on
it any minimum borrowing requirements, reserve or escrow balances, or
compensating balances relating in any way to this Agreement. In no event shall
the amount of interest due and payable under this Agreement, the Note or any of
the other financing documents exceed the maximum rate of interest allowed by
applicable law and, in the event any such payment is inadvertently made by the
Company or inadvertently received by the Investor, such excess sum shall be
credited as a payment of principal. It is the express intent hereof that the
Company not pay and the Investor not receive, directly or indirectly or in any
manner, interest in excess of that which may be lawfully paid under applicable
law.

conducted. The Company is duly qualified, in good standing and authorized to do
business in each jurisdiction in which the character of its properties or the
nature of its businesses requires such qualification or authorization, except

               (b) The Common Stock or other equity securities issuable upon
conversion of the Note in accordance with its terms, shall be prior to issuance,
duly authorized and reserved for issuance and, when issued, will be duly

          5.2 Authorization. The Company has the corporate power and has taken
              -------------
all necessary corporate action to authorize it to issue, sell and deliver the
Note and to execute, deliver and perform this Agreement and the Note, in
accordance with their respective terms, and to consummate the transactions
contemplated hereby and thereby. This Agreement has been duly executed and
delivered by the Company and is, along with the Note, a legal, valid and binding
obligation of the Company enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, moratorium, or other
laws affecting the enforcement of creditors' rights generally or by general
equitable principles (regardless of whether such enforceability is considered in
an action, suit or proceeding in equity or at law).

          5.3 Subsidiaries. The Subsidiaries of the Company are listed on
              ------------

Materially Adverse Effect. The Company owns all of the outstanding capital stock
of each Subsidiary, except as set forth on Schedule 5.3.
                                           ------------

          5.4 Compliance with Other Documents and Contemplated Transactions. The
              -------------------------------------------------------------
execution, delivery and performance by the Company of this Agreement and the
Note in accordance with their respective terms, and the consummation of the
transactions contemplated hereby and thereby, do not and will not (i) require

been obtained from, or require the Company to effect any filing or registration
which has not already been effected with, any federal, state or local regulatory
authority, (ii) violate any Applicable Law with respect to the Company, except
any such violation which would not be reasonably likely to have a Materially
Adverse Effect, (iii) conflict with, result in a breach of, or constitute a
default under (a) the Certificate of Incorporation or the

<PAGE>

Bylaws of the Company or (b) any indenture, agreement, credit facility or other
instrument to which the Company or any Subsidiary of the Company is a party or
by which any such company or its properties may be bound or (iv) result in or
require the creation or imposition of any Lien upon or with respect to any
property now owned or hereafter acquired by the Company or any of its
Subsidiaries.

              -------------------                         ------------
the Company is in substantial compliance with all Applicable Laws, except any
non-compliance which would not be reasonably likely to have a Materially Adverse
Effect.

          5.6 Title to Properties. Except as set forth on Schedule 5.6, the
              -------------------                         ------------
Company has good and marketable title to, or a valid leasehold interest in, all
of its assets. None of such assets is subject to any Liens, except for Permitted
Liens. Except for financing statements evidencing Permitted Liens, no financing
statement under the Uniform Commercial Code and no other filing which names the
Company as debtor or which covers or purports to cover any of the Company's
assets is on file in any state or other jurisdiction, and the Company has not
signed any such financing statement or filing (except as described above) or any
security agreement that has not been terminated, authorizing any secured party
thereunder to file any such financing statement or filing.

          5.7 Litigation. There is no action, suit or proceeding pending or, to
              ----------
the best of the Company's knowledge, threatened against or in any other manner
relating directly and adversely to, the Company or any of its properties in any
court or before any arbitrator of any kind or before or by any governmental
body, except as described on Schedule 5.7 attached hereto, and no such action,
                             ------------
suit, proceeding or investigation (i) calls into question the validity of this
Agreement, or (ii) if determined adversely to the Company, would be reasonably
likely to have a Materially Adverse Effect.

          5.8 Taxes. All federal, state and other tax returns of the Company and
              -----
its Subsidiaries required by law to be filed have been duly filed and all
federal, state and other taxes, assessments and other governmental charges or
levies upon the Company and any of its Subsidiaries and any of their properties,
income, profits and assets, which are due and payable, have been paid, except
any such taxes, assessments or other governmental charges or levies (i) the
payment of which is being contested in good faith by appropriate proceedings,
(ii) for which adequate reserves have been provided on the books of the Company
and (iii) as to which no Lien other than a Permitted Lien has attached and no
foreclosure, distraint, sale or similar proceedings have been commenced. The
charges, accruals and reserves on the books of the Company in respect of taxes
are, in the judgment of the Company, adequate.

          5.9 Financial Statements. The Company has furnished or caused to be
              --------------------
furnished to the Investor its consolidated audited balance sheet and statements
of operations and cash flows for the fiscal year ended January 29, 2000 and its
consolidated unaudited balance sheet and statements of operations and cash flows
for the nine (9) month period ending October 28, 2000 (collectively, the
"Financials"), which as of the date hereof are complete and correct in all
respects and present fairly in accordance with generally accepted accounting
principles the Company's financial position on and as at such dates and the
results of operations for the periods
<PAGE>

then ended. There are no liabilities, contingent or otherwise, of the Company
which are not disclosed in such Financials.

          5.10 No Adverse Change. Since January 29, 2000, there has occurred no
               -----------------
event which is reasonably likely to have a Materially Adverse Effect.

          5.11 ERISA. The Company and each ERISA Affiliate and each of their
               -----
respective Plans are in substantial compliance with ERISA and the Internal
Revenue Code (the "Code"), and neither the Company nor any of its ERISA
Affiliates has incurred any accumulated funding deficiency with respect to any
such Plan within the meaning of ERISA or the Code. The Company has not incurred
any material liability to the Pension Benefit Guaranty Corporation or any
successor thereto in connection with any such Plan. The assets of each such Plan
which is subject to Title IV of ERISA are sufficient to provide the benefits
under such Plan for which the Pension Benefit Guaranty Corporation or any
successor thereto would guarantee payment if such Plan were terminated, and such
assets are also sufficient to provide all other benefits due under the Plan
prior to and upon termination. No Reportable Event has occurred and is
continuing with respect to any such Plan. No such Plan or trust created
thereunder, or any party in interest, fiduciary, trustee or administrator
thereof, has engaged in a "prohibited transaction" (as such term is defined in
Section 406 of ERISA or Section 4975 of the Code) which would subject such Plan
or any other Plan of the Company, or any of its ERISA Affiliates, any trust
created thereunder, or any party in interest, fiduciary, trustee or
administrator thereof, or any party dealing with any such Plan or any such trust
to the tax or penalty on "prohibited transactions" imposed by Section 502 of
ERISA or Section 4975 of the Code. Neither the Company nor any of its ERISA
Affiliates is a participant in or obliged to make any payment to a
Multi-employer Plan.

          5.12 Absence of Default, etc. The Company is in compliance with all
               -----------------------
the provisions of its Certificate of Incorporation and Bylaws, and no event has
occurred or failed to occur, which has not been remedied or waived, the
occurrence or non-occurrence of which constitutes, or which with the passage of
time or giving of notice or both would constitute a default or breach by the
Company under any indenture, agreement, credit facility or other instrument
(collectively, the "Company Agreements") or under any judgment, decree or order
to which the Company or any of its Subsidiaries is a party or by which the
Company or any of its Subsidiaries or their properties may be bound or affected,
except any such default or breach which would not be reasonably likely to have a
Materially Adverse Effect. All Company Agreements are in full force and effect,
and the Company has no knowledge that any party to any Company Agreement is
seeking or presently intends to seek to (i) terminate, amend or modify such
Company Agreement or (ii) upon expiration of such Company Agreement, not renew
such Company Agreement on terms substantially similar to those currently
contained in such Company Agreement.

          5.13 Intellectual Property Rights. The Company owns or possesses
               ----------------------------
sufficient legal rights to all patents, patent applications, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, know-how, concepts,
computer programs and software, technical data, proprietary rights, proprietary
processes and other information necessary for its business as previously
conducted, as now conducted and as currently proposed to be conducted by the
Company (each such item, the "Company Intellectual Property") without any
conflict
<PAGE>

with or infringement of the rights of others. Schedule 5.13 contains a complete
                                              -------------
list of all issued patents, service marks, trademarks and registered copyrights
of the Company, any pending applications therefor and registrations, renewals,
extensions and the like thereof and all other patentable Company Intellectual
Property as to which the Company intends to file applications describing where
the Company is currently in the application process. Except for proprietary
information agreements with its employees and consultants, and licenses or
agreements entered into in the ordinary course of the Company's business,
consistent with past practices, there are no outstanding options, licenses, or
agreements of any kind relating to any of the Company Intellectual Property, nor
is the Company bound by or a party to any options, licenses, or agreements of
any kind with respect to the patents, patent applications, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, know-how, concepts,
computer programs, technical data, proprietary rights, proprietary processes and
information of any other person or entity. No person or entity has the right to
purchase any of the Company Intellectual Property owned by the Company. Each of
the federal, state and other governmental registrations with any country
pertaining to the Company Intellectual Property is valid and in full force and
effect. No claims are pending against the Company by any person with respect to
the use of any Company Intellectual Property or challenging or questioning the
validity or effectiveness of any license or agreement relating to the same. To
the best of the Company's knowledge, none of its employees, agents or
contractors is obligated under any contract (including licenses, covenants, or
commitments of any nature) or other agreement, or is 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 interests of the
Company, or that would conflict with the Company's business as it is currently
proposed to be conducted. To the best of the Company's knowledge, neither the
execution nor 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 currently proposed will 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. The Company has no plan to, and does not believe it is or will be
necessary to utilize, any inventions of any of its employees (or individuals it
currently intends to hire) made prior to their employment by the Company that
would infringe the rights of others. Schedule 5.13 sets forth a list of all
                                     -------------
jurisdictions in which the Company is operating under a trade name, and each
jurisdiction in which any such trade name is registered. No patent listed on
Schedule 5.13 has been or is now involved in any interference, reissue,
-------------
reexamination or opposition proceeding, nor is the Company aware of any
potentially interfering patent or patent application of any third party. No
person or entity is presently selling or marketing a product which is covered by
such patents, and such patents have not been challenged or threatened in any
way. None of the current or former employees of the Company are named as an
inventor on any pending patent application. All patents listed on Schedule 5.13
                                                                  -------------
are currently in compliance with formal legal requirements (including payment of
filing, examination and maintenance fees and proofs of working or use), and,
there is nothing which would render such patents invalid or unenforceable, and
they are not subject to any maintenance fees or taxes or actions falling due
within ninety days after the date of Closing.

          5.14 Environmental Matters. Except as is described on Schedule 5.14
               ---------------------                            -------------

or any other Person any complaint, notice of violation, alleged violation,
investigation or advisory action or notice of potential liability regarding

Environmental Laws with regard to the Properties, nor is the Company aware that
any governmental authority is contemplating delivering to the Company any such
notice. There has been no pending or, to the Company's knowledge, threatened

potential liability under Environmental Laws with regard to any of the
Properties.

               (d) Hazardous Materials have not been generated, treated, stored,
disposed of, at, on or under any of the Property, except in substantial
compliance with all Environmental Laws, or in a manner that could give rise to

location, except in substantial compliance with all Environmental Laws, nor in a
manner that could reasonably be anticipated to give rise to material liability
under Environmental Laws.

               (e) The Company is not a party to any governmental,
administrative actions or judicial proceedings pending under any Environmental
Law with respect to any of the Properties, nor are there any consent decrees or
other decrees, consent orders, administrative orders or other orders, or other

with respect to any of the Properties.

               ----------------------------------------------------------
Company is not: (i) an "investment company" or a Company "controlled by an
investment company" or (ii) required to register, in each case, under the
provisions of the Investment Company Act of 1940, as amended, and neither the
entering into or performance by the Company of this Agreement violates any
provision of such Act or requires under such Act any consent, approval or
authorization of, or registration with, the Securities and Exchange Commission
(the "Commission") or any other governmental or public body or authority
pursuant to any provisions of such Act. The Company is not a "public utility
holding company" within the meaning of the Public Utility Holding Company Act of

(the "Securities Act") and from the registration or qualification requirements
of the laws of any applicable state or other jurisdiction, and neither the
