                               PURCHASE AGREEMENT


         This Series C Preferred Stock Purchase Agreement (this "Agreement"),
dated as of March 3, 2000, is by and among (i) NET VALUE HOLDINGS, INC., a
Delaware corporation (the "Company"), and (ii) the Purchasers listed on the
Purchaser Schedule attached hereto (each individually, a "Purchaser," and all of
them, collectively, the "Purchasers").

         Capitalized terms used and not otherwise defined upon first usage
herein are defined in Section 9.1 hereof.

1.       Sale And Purchase of Purchased Shares.

         1.1. Agreement to Sell and Purchase Purchased Shares. The Company
hereby agrees to issue and sell to each Purchaser and, subject to all of the
terms and conditions hereof and in reliance on the representations and
warranties set forth or referred to herein, each Purchaser severally agrees to
purchase (i) such number of shares (collectively, the "Purchased Shares") of
Series C Preferred Stock (also referred to herein as the "Series C Preferred")
as is equal to the result obtained when the aggregate purchase price (as to each
Purchaser, the "Aggregate Purchase Price") being paid by each such Purchaser (as
set forth opposite such Purchaser's name on the Purchaser Schedule attached
hereto as Exhibit A) is divided by the Per Share Purchase Price (as such term is
defined in Section 1.2, below) therefor, and (ii) a Closing Warrant exercisable
for such number of shares of Common Stock as is set forth opposite such
Purchaser's name on the Purchaser Schedule attached hereto as Exhibit A. The
term "Purchased Shares" as used in this Agreement also includes any securities
issued or issuable with respect to the original Purchased Shares upon the
occurrence of an Adjustment Event and any securities into which any of the
original Purchased Shares are converted or convertible, directly or indirectly,
or for which any of the original Purchased Shares are exchanged or exchangeable,
directly or indirectly.

         1.2. Purchase Price. The purchase price per share (the "Per Share
Purchase Price") to be paid at Closing by the Purchasers for each of the
Purchased Shares shall be equal to the lesser of (i) $12.00 per share (as
adjusted on the occurrence of an Adjustment Event if the Closing Date shall
occur after the date of this Agreement), and (ii) 80% of the average of the
closing market prices of the Common Stock on each of the three (3) trading days
prior to the occurrence of the Closing Date; provided, however, that if the Per
Share Purchase Price as calculated pursuant to clauses (i) and (ii) of this
sentence would be less than $6.00 per share, (as adjusted from time to time on
the occurrence of an Adjustment Event) then (x) the Per Share Purchase Price
shall be equal to $6.00 per share (as adjusted from time to time on the
occurrence of an Adjustment Event), and (y) the Purchasers shall in such case be
under no obligation to consummate the purchase of the Purchased Shares pursuant
to the terms of this Agreement; provided, further, that the Per Share Purchase
Price shall be equitably adjusted on the occurrence of an Adjustment Event. No
consideration in addition to the Aggregate Purchase Price payable by each
Purchaser in respect of the Purchased Shares being purchased by such Purchaser
shall be payable by such Purchaser in respect of the Closing Warrant being
issued to such Purchaser at Closing.

         1.3. Closing. The closing of the initial purchase and sale of the
Purchased Shares (the "Closing") will take place on or before March 3, 2000 at
the offices of Bingham Dana LLP, 150 Federal Street, Boston, Massachusetts
02110, simultaneously with the execution and delivery of this Agreement, or at
such other time, date, and place as the Company and the Purchasers may agree
(the date on which the Closing actually occurs, the "Closing Date").

         In order to induce the Purchasers to enter into this Agreement and to

each of the Purchasers, as follows:

         2.1. Organization and Authority. The Company is a corporation duly
organized, validly existing, and in good standing under the laws of the State of
Delaware. The Company has all requisite corporate power and authority to own or
lease and operate its properties and to carry on its business as now conducted
and as proposed to be conducted.

         2.2. Corporate Power; Binding Effect; Non-Contravention. The Company
has all requisite power and full legal right to execute and deliver this
Agreement and the Ancillary Agreements, and to perform all of its obligations
hereunder and thereunder in accordance with the respective terms hereof and
thereof. This Agreement and the Ancillary Agreements and the transactions
contemplated hereby and thereby have been duly approved and authorized by all
requisite




<PAGE>


                                       -4-

corporate action on the part of the Company, and this Agreement has been duly
executed and delivered by the Company and constitutes, and each of the Ancillary
Agreements, when executed and delivered by the Company at the Closing, will
constitute, a legal, valid, and binding obligation of the Company, enforceable
against it in accordance with its respective terms. The execution, delivery, and
performance by the Company of this Agreement and the Ancillary Agreements in
accordance with their respective terms, and the consummation by the Company of
the transactions contemplated hereby or thereby, will not result (with or
without the giving of notice or the lapse of time or both) in any conflict,
violation, breach, or default, or the creation of any Lien, or the termination,
acceleration, vesting, or modification of any right or obligation, under or in
respect of (x) the charter documents or by-laws of the Company, (y) any
judgment, decree, order, statute, rule, or regulation binding on or applicable
to the Company, or (z) any agreement or instrument to which the Company is a
party or by which it or any of its assets is or are bound.

         2.3. Foreign Qualification. The Company is duly qualified to do
business and in good standing as a foreign corporation in the Commonwealth of
Pennsylvania and the State of California, which jurisdiction is the only
jurisdiction in which the character of the properties owned or leased by it or
the nature of its activities makes such qualification necessary, other than any
jurisdictions in which the failure so to qualify or be in good standing would
not, either in any case or in the aggregate, have a Material Adverse Effect.

         2.4. Subsidiaries. The Company does not have any Subsidiaries nor does
it own any legal and/or beneficial interests in any other Person other than as
set forth on Schedule 2.4 hereto.

         2.5. Capitalization.

         (a) Immediately prior to the Closing, not giving effect to the sale and
purchase of the Purchased Shares or any of the other Acquired Securities
provided for in this Agreement, the authorized and the outstanding capital stock
of the Company (on a fully diluted basis including all Derivative Securities)
will be as set forth in Schedule 2.5(a), and all such outstanding shares of
capital stock will be owned (of record and beneficially) by the persons and in
the amounts there indicated. All such outstanding shares of capital stock will
be duly authorized, validly issued, fully paid, and nonassessable, and will have
been issued free and clear of Liens. No adjustment has previously been made (or
should have been made) nor will any adjustment be required to be made as a
result of the Company's issuance of the Purchased Shares or any of the other
Acquired Securities to the rate at which shares of Series A Preferred Stock, the
Series B Preferred Stock and any other capital stock or Derivative Securities of
the Company are convertible into or exercisable for shares of Common Stock (by
reason of any "anti-dilution" provisions or agreements or otherwise).

         (b) Except as set forth in Schedule 2.5(b), the Company does not have,
is not bound by, and has no obligation to grant or enter into, any (i)
outstanding subscriptions, options, warrants, calls, commitments, or agreements
of any character calling for it to issue, deliver, or sell, or cause to be
issued, delivered, or sold, any shares of its capital stock, any membership
interests or any other equity security, or any securities described in the
following clause, or (ii) securities convertible into, exchangeable for, or
representing the right to subscribe for, purchase, or otherwise acquire any
shares of its capital stock, any membership interests or any other equity
security. Except as set forth in Schedule 2.5(b), no adjustment has previously
been made (or should have been made) nor will any adjustment be required to be
made as a result of the Company's issuance of the Purchased Shares or any of the
other Acquired Securities to the number of shares of capital stock or Derivative
Securities of the Company into which any subscriptions, options, warrants,
calls, commitments or agreements are convertible (by reason of any
"anti-dilution" provisions or agreements or otherwise).

                                       -5-



         (c) Except as set forth in Schedule 2.5(c), the Company (i) has no
outstanding obligations, contractual or otherwise, to repurchase, redeem, or
otherwise acquire any shares of capital stock or other equity securities of the
Company, (ii) is not a party to or bound by, and has no knowledge of, any
agreement or instrument relating to the voting of any of its securities, and
(iii) is not a party to or bound by any agreement or instrument under which any
person has the right to require it to effect, or to include any securities held
by such person in, any registration under the Securities Act. There are no other
agreements, contracts, instruments or documents, except as set forth in Schedule
2.5(c), which govern or affect in any way the rights of the holders of
securities, including any class of capital stock, of the Company.

         (d) The Company has reserved, solely for the purpose of issuance upon
conversion of shares of Series C Preferred and upon exercise of the Closing
Warrants and Compensation Warrants (if any), a number of shares of Common Stock
sufficient to cover the conversion of all such shares of Series C Preferred and
exercise of the Closing Warrants and Compensation Warrants (if any), as the case
may be. The Company has reserved, solely for the purpose of issuance of any
Dividend Shares as may be issued, a sufficient number of shares of Series C
Preferred to cover any such issuance.

         2.6. Lawful Issuance. All of the outstanding shares of capital stock,
membership interests, and other securities of the Company were offered, issued,
and sold, and the Purchased Shares and other Acquired Securities have been
offered and at the Closing will be issued and sold, in compliance with (i) all
applicable preemptive or similar rights of all persons, and (ii) assuming the
truthfulness and accuracy of the representations made by the Purchasers in
Section 3 hereof, all applicable provisions of the Securities Act and the rules
and regulations thereunder, and all applicable state securities laws and the
rules and regulations thereunder. No person has any valid right to rescind any
purchase of any shares of capital stock or other securities of the Company.

         2.7 Valid Issuance of Purchased Shares. The Purchased Shares and other
Acquired Securities being issued and sold by the Company hereunder shall, upon
issuance pursuant to the terms hereof, be duly authorized and validly issued,
fully paid and non-assessable and free and clear of any Lien, security interest,
option or other charge or encumbrance. The Common Stock issuable upon the
conversion of the Purchased Shares and exercise of the Closing Warrants and
Compensation Warrants (if any), as the case may be, shall be duly authorized and
validly issued, fully paid and non-assessable and free and clear of any Lien,
security interest, option or other charge or encumbrance. The issuance of the
Purchased Shares and other Acquired Securities are not and will not be subject
to any pre- emptive rights or similar rights with respect to such Purchased
Shares and other Acquired Securities.

         2.8.     Financial Statements.

         The Company has delivered to the Purchasers copies of (i) the unaudited
balance sheet of the Company as of December 31, 1999, and the related statements
of profit and loss and changes in stockholders' equity for the twelve month
period ended on that date, and (ii) the unaudited balance sheet of the Company
as of December 31, 1999 (the "Most Recent Balance Sheet"), and the related
unaudited statements of profit and loss for the period commencing January 1,
2000 and ended on January 31, 2000. Each of such financial statements was
prepared in accordance with GAAP applied on a basis consistent with prior
periods, subject, in the case of the unaudited financial statements referred to
above to the absence of footnotes, and subject to adjustments consisting of
normal year-end accruals, the effect of which absence of footnotes and year-end
accruals, both individually and in the aggregate, is not in any case material.
Each of such balance sheets is true and correct in all material respects and
fairly presents the financial condition of the Company as of its date; and each
of such statements of profit and loss fairly presents the results of operations
of the Company for the period covered thereby.

been:

         (a) any (i) acquisition (by purchase, lease as lessee, license as

licensor, or otherwise) by the Company of any material properties or assets, or
(ii) other transaction by, or any agreement or commitment on the part of, the

Adverse Effect, except as set forth on Schedule 2.9(a);

         (b) any material change in the condition (financial or otherwise),

Effect;

         (c) any material transaction or material change in compensation by the

         (d) any damage, destruction, or loss, whether or not covered by
insurance, that, either in any case or in the aggregate, has caused, or could
reasonably be expected to cause, a Material Adverse Effect;

         (e) any declaration, setting aside, or payment of any dividend or any
other distribution (in cash, stock, and/or property or otherwise) in respect of
any shares of the capital stock or other securities of the Company;

         (f) any issuance of any shares of the capital stock or other securities

employees, or independent contractors, or any bonus payments or arrangements
made to or with any of such officers, employees, or independent contractors,
except as set forth in Schedule 2.9(h);

         (i) any forgiveness or cancellation of any debt or claim by the Company
or any waiver by the Company of any right of material value, other than

<PAGE>
                                       -7-

Company, or (ii) on any of the capital stock, other securities, properties, or

         (l) any material change in the financial or tax accounting principles,

referred to in this Section 2.9.

         2.10.    Properties, Leases, Etc.

         (a) Title to Properties; Condition of Personal Properties. The Company
has (i) good and marketable title to all of the assets and properties owned by
it, including without limitation all assets and properties reflected in the Most
Recent Balance Sheet (in each case excluding any assets and properties sold or
otherwise disposed of to persons other than Affiliates in the ordinary course of
business since the date of such balance sheet), free and clear of all Liens,
(ii) valid title to the lessee interest in all assets and properties leased by
them as lessee, free and clear of all Liens, and (iii) full right to hold and
use all of its assets and properties used in or necessary to its businesses and
operations, in each case all free and clear of all Liens, and in each case
subject to applicable laws and the terms of any lease under which the Company
leases such assets or properties as lessee; except where the failure to have the
title or right set forth in clauses (i) through (iii) would not have a Material
Adverse Effect. All such assets and properties are in good condition and repair,
reasonable wear and tear excepted, and are adequate and sufficient to carry on
the businesses of the Company as presently conducted and as proposed to be
conducted.

         (b) No Owned Real Properties. The Company does not own any real
property or any interest (other than a leasehold interest) in any real property.

         (c) Leased Properties. Schedule 2.10(c) sets forth a complete and
correct description of all leases of real or personal property under which the
Company is lessor or lessee. Complete and correct copies of all such leases and
all amendments, supplements, and modifications thereto, other than any personal
property lease with an annual rent of less than $10,000 and total remaining
rental payments of less than $20,000, have been delivered to the Purchasers.
Each such lease is valid and subsisting and no event or condition exists that
constitutes, or after notice or lapse of time or both would constitute, a
default thereunder by the Company or, to the Company's knowledge, any other
party thereto. The Company's leasehold interests are subject to no Lien, and the
Company is in quiet possession of the properties covered by such leases. The
Company has established adequate reserves which are reflected in the Most Recent
Balance Sheet, for the anticipated costs of any property renovation and repairs
to its leased premises required to be performed or paid for by it upon
termination of any of its leases of real property.

         2.11. Indebtedness. Except to the extent reflected or reserved in the
Most Recent Balance Sheet, and except as set forth on Schedule 2.11, the Company
has no Indebtedness in excess of $25,000 outstanding. The Company is not in
default with respect to any outstanding Indebtedness or any instrument or
agreement relating thereto, and no such Indebtedness or any instrument or
agreement relating thereto purports to limit the issuance of any securities by
the Company or the operation of its business. Complete and correct copies of all
instruments and agreements (including all amendments, supplements, waivers, and
consents) relating to any Indebtedness of the Company have been furnished to the
Purchasers.

         2.12. Absence of Undisclosed Liabilities. Except to the extent
reflected or reserved in the Most Recent Balance Sheet, and except as set forth
on Schedule 2.12, or incurred after the date of such balance sheet in the
ordinary course of business (other than in connection with any transactions with
Affiliates), or incurred in connection with the transactions contemplated by
this Agreement and described in Schedule 2.9(j), the Company does not have any
material liabilities or obligations of any nature, whether accrued, absolute,
contingent, or otherwise (including without limitation liabilities as guarantor
or otherwise with respect to obligations of others) and whether due or to become
due.

         2.13.    Tax Matters.

         (a) Filing of Tax Returns and Payment of Taxes. The Company has filed
all Tax Returns required to be filed by it, each such Tax Return has been
prepared in compliance with all applicable laws and regulations, and all such
Tax Returns are true and accurate in all material respects. All Taxes due and
payable by the Company have been paid, and the Company will not be liable for
any additional Taxes in respect of any taxable period ending on or before the
Closing Date in an amount that exceeds the corresponding reserve therefor, if
any, reflected in the accounting records of the Company as of the Closing Date.
No claim has ever been made by a taxing authority in a jurisdiction where the
Company does not pay Tax or file Tax Returns that the Company is or may be
subject to Taxes assessed by such jurisdiction. There are no Liens for Taxes
(other than current Taxes not yet due and payable) on the assets of the Company.

         (b) Audit History, Extensions, Etc. There is no action, suit, taxing
authority proceeding, or audit with respect to any Tax now in progress, pending,
or to the best of the Company's knowledge, threatened, against or with respect
to the Company. No deficiency or proposed adjustment in respect of Taxes that
has not been settled or otherwise resolved has been asserted or assessed by any
taxing authority against the Company. The Company has not consented to extend
the time in which any Tax may be assessed or collected by any taxing authority.
The Company has not requested or been granted an extension of the time for
filing any Tax Return to a date on or after the Closing Date.

         (c) Membership in Affiliated Groups, Etc. The Company has never been a
member of any Affiliated Group, or filed or been included in a combined,
consolidated, or unitary Tax Return. The Company is not a party to or bound by
any tax sharing or allocation agreement or has any current or potential
contractual obligation to indemnify any other person with respect to Taxes.

         (d) Withholding Taxes. The Company has withheld and paid all Taxes
required to have been withheld and paid by it in connection with amounts paid or
owing to any employee, creditor, independent contractor, or other Person.

         2.14. Litigation, Etc. Except as set forth in Schedule 2.14, no
litigation, arbitration, action, suit, claim, demand, proceeding or
investigation (whether conducted by or before any judicial or regulatory body,
arbitrator, commission or other person) is pending or, to the Company's
knowledge, threatened, against the Company, nor is there any basis therefor
known to the Company, where an adverse result would have a Material Adverse
Effect.

         2.15.    Safety, Zoning, and Environmental Matters.

         (a) The Company is not nor has it been in violation in any material
respect of any applicable statute, law, or regulation relating to occupational
health or safety, and no charge, complaint, action, suit, proceeding, hearing,
investigation, claim, demand, or notice has been filed or commenced against or
received by it alleging any failure by it to comply with any such statute, law,
or regulation, nor is there any basis therefor known to the Company.

         (b) To the best of the Company's knowledge, none of the real properties
presently owned, leased, or operated by the Company, nor any leasehold
improvements thereto, nor any business conducted by the Company thereon, are in
violation of any applicable land use or zoning requirements, including without
limitation any building line or use or occupancy restriction, any public utility
or other easement, any limitation, condition, or covenant of record, or any
zoning or building law, code, or ordinance, where such violation would have a

provider thereof and there is no basis for any such legal action or proceeding.

Section 4975 of the Code.

             (3) No communication, report, or disclosure has been made that, at

Employee Benefit Plan.

             (4) No Employee Benefit Plan provides welfare benefits subsequent
to termination of employment to employees or their beneficiaries (except to the
extent required by applicable state insurance laws and Title I, Part 6 of
ERISA).

             (5) The Company has not undertaken to maintain any Employee Benefit
Plan for any specific period of time and each such plan is terminable at the
sole discretion of the Company, subject only to such constraints as may imposed
by applicable law.

bargaining agreement or is or has been subject to the minimum funding

Plan for which a separate fund of assets is or is required to be maintained,
full payment has been made of all amounts that, under the terms of each such
plan, it is required to have paid as contributions to that plan as of the end of
such plan's most recently ended year.

charging the Company with infringement or unlawful use of any patent, trademark,
copyright, or other proprietary right is pending or, to the Company's knowledge,
threatened; nor is there any basis for any such litigation or proceeding.

         (d) No officer, director, employee, or consultant of the Company is
presently obligated under or bound by any agreement or instrument, or any

usually carried by reasonable and prudent companies conducting businesses
similar to that of the Company (such insurance coverage at all times to be at
least as protective as the insurance currently carried by the Company and
described in Schedule 2.21). The Company shall not cause or permit any
assignment or change in beneficiary and shall not borrow against any such
policy.

         5.13. Taxes. The Company will pay and discharge, or cause to be paid
and discharged, before they become delinquent, all taxes, assessments, and other
governmental charges imposed upon the Company or any of the properties, sales,
or activities of the Company, or any part thereof, or upon the income or profits
therefrom, as well as all claims for labor, materials, or supplies, which, if
unpaid might by law give rise to a Lien upon any of its properties; provided,
however, that any such tax, assessment, charge, levy, or claim need not be paid
if the validity or amount thereof is currently being contested in good faith by
appropriate proceedings and if the Company has set aside on its books adequate
reserves with respect thereto.

         5.14. Compliance with Laws, Contracts, Licenses, and Permits. The
Company will comply in all material respects with (a) its charter documents and
by-laws, (b) all judgments, decrees, orders, statutes, rules, and regulations
binding on or applicable to the Company or its business or properties, and (c)
any agreement or instrument to which it is a party or by which it or any of its
properties are subject (including, without limitation, the Ancillary
Agreements). If at any time any authorization, consent, approval, permit, or
license from any officer, agency, or instrumentality of any government becomes
necessary or required in order that the Company may fulfill any of its
obligations hereunder, the Company will, after providing adequate written notice
to the holders of shares of Series C Preferred Stock, promptly take or cause to
be taken all necessary steps within its power to obtain such authorization,
consent, approval, permit, or license and will, upon written request, promptly
furnish each such holder with evidence thereof.

         5.15. Employee Benefit Plans. The Company will take all actions
necessary to maintain, fund, and administer its Employee Benefit Plans in all
material respects in accordance with applicable federal, state, and local law.

         5.16. Compensation of Officers and Senior Management. The compensation
of all officers and senior management of the Company will be as determined from
time to time by the Compensation Committee (if any) of the Board of Directors.

         5.17. Reservation of Shares; Compliance with Securities Laws. The
Company has and will continue at all times to reserve the appropriate number of
shares of Common Stock solely for the purpose of issuance upon conversion of
outstanding shares of Series C Preferred Stock and exercise of the Closing
Warrants and Compensation Warrants (if any). The Company will file within the
required time periods all filings, notices and other documents required by
applicable federal and state securities laws in connection with the transactions
contemplated by this Agreement.

         5.18. Senior Management and Employee Non-Disclosure Agreement. The
Company will at all times ensure that (a) each employee, including each member
of senior management, has executed and delivered to the Company the standard
form agreement (approved by the non- management members of the Company's Board
of Directors) with respect to the confidentiality of the Company's proprietary
and confidential information and the assignment to the Company of any and all
rights each employee might have or acquire with respect to technology,
inventions, developments, etc., developed in connection with his/her employment
with the Company, and (b) each member of the Company's senior management and
certain other key employees, in each case that the Chief Executive Officer and
the Chief Operating Officer shall have determined is appropriate, has executed
and delivered to the Company a confidentiality, non-disclosure, inventions
assignment and non-competition and non-solicitation agreement approved by the
non-management members of the Board of Directors.

         5.19. Intentionally Omitted.

         5.20 Registration Requirements.

         (a) No earlier than April 1, 2000, but no later than May 31, 2000, the
Company shall (i) file with the SEC a registration statement on Form S1
(together with any prospectus included therein, a "Registration Statement")
pursuant to Rule 415 of the Securities Act in order to register with the SEC the
continuous resale by the Purchasers, from time to time, of all shares of Common
Stock constituting Immediately Registrable Securities that may be acquired by
the Purchasers, through the Nasdaq SmallCap Market or the facilities of any
national securities exchange on which the Common Stock is then traded, or in
privatelynegotiated transactions, and (ii) use its reasonable best efforts to
file an application for listing (a "Listing Application") of such Common Stock
on the NASDAQ SmallCap Market (the "NSCM") or any other nationally recognized
securities exchange (collectively with the NSCM, the "Exchange"). The Company
shall use its best efforts to cause such Registration Statement to be declared
effective on or before the 90th day after the Closing Date; provided, however,
that if the SEC shall not have declared such Registration Statement effective on
or before the 120th day after the Closing Date, the Company shall then issue a
Compensation Warrant to each Purchaser on the 121st day (the "Compensation
Trigger Date") after the Closing Date and, thereafter, an additional
Compensation Warrant on each 30-day anniversary of such Compensation Trigger
Date for so long as the SEC shall not have declared such Registration Statement
effective. The Company shall further cause a Listing Application covering shares
of Common Stock issued or issuable in respect of, on exercise of, or on
conversion of, or constituting any Acquired Securities to be filed with the
Exchange on or before the 120th day following the Closing Date and shall, upon
filing thereof, use its reasonable best efforts to cause such securities to be
accepted for trading upon the Exchange. Each Purchaser agrees to furnish
promptly to the Company in writing all information required for preparation of
the Registration Statement or thereafter required from time to time to be
disclosed in order to make the information previously furnished to the Company
by such holder not misleading.

         (b) If at any time following the filing of a Registration Statement by
the Company, the Company shall qualify to file a registration statement on Form
S3 under the Securities Act, the Company shall thereafter be entitled to replace
any Form S1 registration statement referred to in Section 5.20(a) above with a
registration statement on Form S3 that has been declared effective by the SEC.
Any such Form S3 used to replace a Form S1 pursuant to this Section 5.20(b),
together with any prospectus included in such Form S3, shall thereafter be
referred to as a "Registration Statement" and any Form S1 that is so replaced
shall cease to be referred to by that term for purposes of this Agreement.

         (c) The Company shall pay all Registration Expenses (as defined below)
in connection with any registration, qualification or compliance hereunder, and
each Purchaser shall pay all Selling Expenses (as defined below) and other
expenses that are not Registration Expenses relating to the Common Stock resold
by such Purchaser. "Registration Expenses" shall mean all expenses, except for
Selling Expenses, incurred by the Company in complying with the registration
provisions herein described, including without limitation, all registration,
qualification and filing fees (including all SEC and Nasdaq fees), printing
expenses, escrow fees, fees and disbursements of counsel for the Company and for
any underwriter (unless paid by such underwriter), blue sky fees and expenses,
the expense of any special audits incident to or required by any such
registration and the reasonable fees and disbursements of one counsel to all
selling Purchasers. "Selling Expenses" shall mean only selling commissions,
underwriting discounts and stock transfer taxes applicable to the Common Stock
sold by each Purchaser and all fees and disbursements of counsel for any
Purchaser (which counsel, if any, shall be additional to the one counsel to all
selling Purchasers referenced in the preceding sentence).



<PAGE>


                                      -19-



         (d) In the case of the registration effected by the Company pursuant to
these registration provisions, the Company will use its best efforts to:

             (1) keep such registration statement on Form S1 or Form S3
effective until the earlier of (A) the second anniversary of the date on which
the Registration Statement first becomes effective, (B) the date as of which all
of the Immediately Registrable Securities have been resold, or (C) the time as
of which all of the Common Stock held by the Purchasers can be sold within a
given threemonth period without compliance with the registration requirements of
the Securities Act pursuant to Rule 144;

             (2) prepare and file with the SEC such amendments and supplements
to the Registration Statement and the prospectus used in connection therewith as
may be necessary to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by the Registration
Statement;

             (3) furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Purchaser from time to time may reasonably request;

             (4) cause all Common Stock registered as described herein to be
listed on each securities exchange and quoted on each quotation service on which
the common equity securities of the Company are then listed or quoted;

             (5) provide a transfer agent and registrar for all Common Stock
registered pursuant to the Registration Statement and a CUSIP number for all
such Common Stock;

             (6) otherwise use its best efforts promptly to comply with all
applicable rules and regulations of the SEC;

             (7) file the documents required of the Company and otherwise use
its best efforts promptly to obtain, if applicable, and maintain requisite blue
sky clearance in (A) all jurisdictions in which any of the Acquired Securities
are originally sold, and (B) all other states specified in writing by a
Purchaser, provided as to clause (B), however, that the Company shall not be
required to qualify to do business or consent to service of process in any state
in which it is not now so qualified or has not so consented; and

             (8) with respect to the initial filing of the Registration
Statement as of the date of declaration of effectiveness, obtain an opinion of
counsel to the Company in customary form and reasonably acceptable to each
Purchaser addressed to each Purchaser selling registrable securities pursuant to
the Registration Statement. The Company shall use its best efforts to qualify
for use of Form S1 or Form S3 under the Securities Act to register the resale of
the Common Stock issuable upon the conversion of the Shares and to maintain such
qualification during the periods described in subsection (c)(i) hereof and to be
listed on the Nasdaq SmallCap market and maintain such listing unless listed on
NASDAQ NMS or another national exchange.

         (e) The Company shall furnish to each Purchaser upon request a
reasonable number of copies of the prospectus and a supplement to or an
amendment of such prospectus as may be necessary in order to facilitate the
public sale or other disposition of all or any of the Common Stock held by the
Purchaser.





<PAGE>


                                      -20-



         (f) With a view to making available to the Purchasers the benefits of
Rule 144 and any other rule or regulation of the SEC that may at any time permit
a Purchaser to sell Common Stock to the public without registration or pursuant
to registration, the Company covenants and agrees to: (i) make and keep public
information available, as those terms are understood and defined in Rule 144,
until the earlier of (A) the second anniversary of the Closing Date or (B) the
date as of which all of the Common Stock shall have been resold: (ii) file with
the SEC in a timely manner all reports and other documents required of the
Company under the Exchange Act; and (iii) furnish to any Purchaser upon request,
as long as the Purchaser owns any Common Stock, (A) a written statement by the
Company that it has complied with the reporting requirements of the Exchange
Act, (B) a copy of the most recent annual or quarterly report of the Company,
and (C) such other information as may be reasonably requested in order to avail
any Purchaser of any rule or regulation of the SEC that permits the selling of
any such Common Stock without registration.

         (g) The Company may, at any time, refuse to permit a Purchaser to
resell any Common Stock pursuant to the Registration Statement; provided,
however, that in order to exercise this right at any time, the Company must
deliver a certificate in writing to the Purchasers, signed by a senior executive
officer of the Company, to the effect that suspension of the sale of shares
under the Registration Statement until such time as the Company can make an
appropriate filing with the SEC is necessary in the good faith determination of
the Company's Board of Directors because a sale pursuant to the Registration
Statement, in its then current form, would be reasonably likely to constitute a
violation of the federal securities laws, which certificate shall specify
whether such filing is required to correct information in the Registration
Statement which was incorrect when included therein (a "Corrective Filing") or
to update or supplement the information therein to reflect new information (a
"Supplemental Filing"). In such an event, the Company shall use its best efforts
to amend the Registration Statement if necessary and take all other actions
necessary to allow such sale under the federal securities laws, and shall notify
the Purchasers promptly after it has determined that such sale has become
permissible under the federal securities laws. Notwithstanding the foregoing,
the Company shall not be entitled to exercise its right to suspend any sales
under the Registration Statement for a Corrective Filing more than one (1) time
in any twelve (12) month period, and the Company shall use its best efforts to
limit any period during which such Registration Statement may be withdrawn,
whether for a Corrective Filing or a Supplemental Filing, to a period not in
excess of thirty (30) days; provided, that all officers and directors of the
Company, and any other Persons to whom the Company has given registration
rights, also agree to suspend the sales of any of the Company's securities owned
by such Person during any such period.

         5.21 Indemnification and Contribution.

         (a) The Company agrees to indemnify and hold harmless each Purchaser
and its officers, directors, controlling persons and affiliates from and against
any losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) to which such Purchaser may become subject (under the Securities Act,
state law, common law or otherwise) insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are
based upon, any untrue statement of a material fact contained in, or omission of
a material fact from, the Registration Statement, or arise out of any failure by
the Company to fulfill any undertaking included in the Registration Statement or
this Agreement, and the Company will, as incurred, reimburse such Purchaser for
any legal or other expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim; provided however, that
the Company shall not be liable in any such case to the extent that such loss,
claim, damage or liability arises out of, or is based upon, an untrue statement
made in such Registration Statement in reliance upon and in conformity with
information furnished to the Company in writing by or on behalf of such
Purchaser specifically


<PAGE>


                                      -21-




for use in preparation of the Registration Statement. The Company will reimburse
the Purchasers for any legal or other expenses reasonably incurred and
documented in investigating, defending or preparing to defend any such action,
proceeding or claim notwithstanding the absence of a judicial determination as
to the propriety and enforceability of the obligations under this section and
the possibility that such payments might later be held to be improper, provided,
that to the extent any such payment is ultimately held to be improper, the
persons receiving such payments shall promptly refund them.

         (b) Each Purchaser, severally and not jointly, agrees to indemnify and
hold harmless the Company from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which the Company
may become subject (under the Securities Act, state law, common law or
otherwise) insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, an untrue
statement made in such Registration Statement in reliance upon and in conformity
with information furnished to the Company in writing by or on behalf of such
Purchaser specifically for use in preparation of the Registration Statement;
provided, however, that no Purchaser shall be liable in any such case for any
untrue statement included in any Prospectus which statement has been corrected,
in writing, by such Purchaser and delivered to the Company before the sale from
which such loss occurred and in no event shall any Purchaser be liable for any
amount in excess of the net proceeds received for the sale of its Common Stock
pursuant to such Registration Statement.

         (c) Promptly after receipt by any indemnified person of a notice of a
claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 5.21, such
indemnified person shall notify the indemnifying person in writing of such claim
or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and the indemnifying person shall have been notified thereof,
the indemnifying person shall be entitled to participate therein, and, to the
extent that it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to the indemnified person. After notice from the
indemnifying person to such indemnified person of the indemnifying person's
election to assume the defense thereof, the indemnifying person shall not be
liable to such indemnified person for any legal expenses subsequently incurred
by such indemnified person in connection with the defense thereof; provided,
however, that if there exists or shall exist a conflict of interest that would
make it inappropriate in the reasonable judgment of the indemnified person for
the same counsel to represent both the indemnified person and such indemnifying
person or any affiliate or associate thereof, the indemnified person shall be
entitled to retain its own counsel at the expense of such indemnifying person.

         (d) If the indemnification provided for in this Section 5.21 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) hereof in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand and the Purchasers
on the other in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities (or actions in respect thereof), as
well as any other relevant equitable considerations. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or a Purchaser on the other and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Company and the Purchasers agree that it would not be just and equitable if
contribution pursuant to this subsection (d) were determined by pro rata
allocation


<PAGE>


                                      -22-



(even if the Purchasers were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable
considerations referred to above in this subsection (d). The amount paid or
payable by an indemnified party as a result of the losses, claims, damages, or
liabilities (or actions in respect thereof) referred to above in this subsection
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this subsection (d), no
Purchaser shall be required to contribute any amount in excess of the amount, if
any, by which the amount received by the Purchaser from the sale of the Common
Stock to which such loss relates exceeds the amount of any damages which such
Purchaser has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Purchasers' obligations in this subsection (d)
to contribute are several in proportion to their respective sales of Common
Stock.

         5.22 U.S. Real Property Holding Corporation. The Company covenants that
it will operate in a manner such that it will not become a "United States real
property holding corporation" as that term is defined in Section 897(c)(2) of
the Internal Revenue Code of 1986, as amended ("USRPHC"), and the regulations
thereunder. The Company agrees to make determinations as to its status as a
USRPHC, and will file statements concerning those determinations with the
Internal Revenue Service, in the manner and at the times required under Reg.
1.897-2(h), or any supplementary or successor provision thereto. Within 30 days
of a request from a Purchaser, the Company will inform the requesting party, in
the manner set forth in Reg. 1.897-2(h) or any supplementary or successor
provision thereto, whether that party's interest in the Company constitutes a
United States real property interest (within the meaning of Internal Revenue
Code Section 897(c)(1) and the regulations thereunder) and whether the Company
has provided to the Internal Revenue Service all required notices as to its
USRPHC status.

         5.23 Permitted Transactions. Notwithstanding any contrary provision
hereof, the Company shall have the right to effect any of the transactions or
other actions set forth on Schedule 5.23 hereto without prior notice to, or the
prior consent of the holders of, the Series C Preferred Stock being required in
connection therewith.

         5A. Pre-Emptive Rights.

         5A.1. Participation Rights. Subject to the exclusions set forth in
Section 5A.3 below, and to the provisions of the following sentence in this
Section 5A.1, if at any time after the Closing and prior to the earlier of (x) a
Qualified Public Offering and (y) the date one (1) year after the occurrence of
Closing, the Company authorizes the offer, issuance, or sale, or offers, issues
or sells to any Person (the "Offeree") any shares of Common Stock, Derivative
Securities (as defined in the Purchase Agreement) or other securities of the
Company (whether as newly issued shares or other securities or from the
Company's treasury) in an offering not registered under the Securities Act, the
Company will first offer to sell, by written notice, to each holder of shares of
Series C Preferred Stock a portion (such holder's "Portion") of such shares or
securities authorized to be offered, issued or sold, or proposed to be offered,
issued or sold equal to the product obtained by multiplying (i) the number of
such shares or securities authorized to be offered, issued or sold, or proposed
to be offered, issued or sold, by (ii) the quotient obtained by dividing (A) the
number of shares of Common Stock held by such holder of Series C Preferred Stock
(for this purpose including on an as-if-converted basis the shares of Conversion
Stock held by such holder), by (B) the sum of (I) the aggregate number of shares
of Common Stock issued and outstanding as of such date and (II) the aggregate
number of shares of Conversion Stock (calculated on an as-if-converted basis).


<PAGE>


                                      -23-


         5A.2. Procedure. Each holder of Series C Preferred Stock will be
entitled (but not obligated) to purchase all or part of such holder's Portion at
the same price and on the same terms as such stock or securities are to be
offered to the Offeree. Each such holder may exercise such purchase rights
within 10 days after receipt of written notice from the Company describing in
reasonable detail the stock or securities to be offered to the Offeree, the
purchase price thereof, the payment terms, and such holder's percentage
allotment. If any such holder fails in whole or in part to exercise the purchase
rights hereunder within such 10-day period (other than by reason of the
Company's failure to comply with the provisions of this Section 5A), then the
other holders of Series C Preferred Stock shall have the right to acquire such
Portion (which right may be exercised by any such holder by indication in such
holder's notice to the Company of its exercise of purchase rights hereunder such
holder's desire to acquire additional securities, or otherwise). If
oversubscribed for, any such Portion not purchased by the holder initially
entitled thereto shall be allocated among the other holders of Purchased Shares
desiring to acquire such Portion pro rata in proportion to the numbers of shares
of Common Stock held by each such other holder (including for this purpose
shares of Conversion Stock, calculated on an as-if-converted basis). The Company
may sell so much, and only so much, of any Portion as to which no holders of
Series C Preferred Stock, having been offered the right to purchase such Portion
in accordance with all of the provisions of this Section 5A, have exercised such
purchase rights, to the Offeree at the same price and on the same terms as those
offered to such holder, provided, that if the whole of such holder's Portion of
such securities is not sold to the Offeree within 60 days following the lapse of
the 10-day exercise period provided to the holders of Series C Preferred Stock,
such unsold securities will once again be subject to the purchase rights
hereunder. In the event that shares of Common Stock or Derivative Securities are
authorized to be issued and sold by the Company for services, property, or other
non-cash consideration, each holder of Series C Preferred Stock will be allowed
to participate in such issue and sale by substituting cash in the amount of the
fair market value, per share, of such non-cash consideration.

         5A.3. Excluded Transactions. The prohibitions and rights provided in
this Section 5A will not apply to (i) shares of Common Stock issued by the
Company pursuant to stock dividends, stock splits, recapitalizations, and
similar transactions; (ii) shares of Common Stock issued upon conversion or
exchange, directly or indirectly, of the Series C Preferred Stock; (iii) options
or other rights to purchase or receive Common Stock, and any shares of Common
Stock issued upon the exercise thereof or upon such a purchase, in each case to
officers, directors, consultants, agents and employees of the Company pursuant
to the Company's incentive stock option plan or other equity incentive plan,
each as approved by a majority of the non-management members of the Board of
Directors; (iv) shares of Common Stock issued pursuant to a registration
statement on Form S-4 or Form S-8 (or any applicable successor form); (v)
non-cash consideration issued or paid in connection with the acquisition of
another entity (whether through merger or otherwise), provided, that such
issuance is otherwise permitted under the terms of the Company's Certificate of
Incorporation; (vi) securities issued in any transaction for a strategic purpose
and not primarily to raise equity capital; and (vii) warrants to purchase
capital stock of the Company (and the capital stock issued upon exercise
thereof) issued to a national banking association and which shall not result in
the right of such national banking association to purchase greater than 1% of
the capital stock of the Company on a fully-diluted basis.

         5A.4. Termination of Rights. The prohibitions and rights provided for
in this Section 5A shall terminate automatically upon the closing of a Qualified
Public Offering.

         6. Registration and Transfer of Securities.

        6.1. Transfer and Exchange of Capital Stock. The Company will maintain
at its principal executive office a register in which will be entered the names
and addresses of the holders of the capital stock and the particulars (including
without limitation the class thereof) of the respective capital stock held by
them and of all transfers of shares of capital stock or conversions of shares of
capital stock from one class to another. Upon surrender at such office of any




<PAGE>


                                      -24-



certificate representing shares of capital stock for registration of conversion,
exchange, or (subject to compliance with applicable federal and state securities
laws and the applicable provisions of this Agreement, including without
limitation the conditions set forth in Section 7.2 hereof) transfer, the Company
will issue, at its expense, one or more new certificates, in such denomination
or denominations as may be requested, for shares of such capital stock and
registered as such holder may request. Any certificate representing shares of
capital stock surrendered for registration of transfer will be duly endorsed, or
accompanied by a written instrument of transfer duly executed by the holder of
such certificate or his attorney duly authorized in writing. The Company will
pay shipping and insurance charges, from and to each holder's principal office,
upon any transfer, exchange, or conversion provided for in this Section 6.1.

         6.2. Replacement of Purchased Shares. In the case of any loss, theft,
destruction, or mutilation of the certificate representing any Purchased Shares,
upon receipt of evidence thereof reasonably satisfactory to the Company, and (i)
in the case of any such loss, theft, or destruction, upon delivery of an
indemnity bond in such reasonable amount as the Company may determine, or (ii)
in the case of any such mutilation, upon the surrender to the Company at its
principal office of such mutilated certificate for cancellation, the Company
will execute and deliver, in lieu thereof, new certificates of like tenor. Any
old stock certificate in lieu of which any such new stock certificate has been
so executed and delivered by the Company will not be deemed to be outstanding
for any purpose of this Agreement or otherwise.

         6.3. Reliance on Register. The Company may rely for all purposes
hereunder on record ownership as shown on the register described in this Section
6 (except to the extent that such register fails to reflect a transfer of which
the Company received due notice in accordance with Section 7.2 of this
Agreement).

         7. Restrictions on Transfer.

         7.1. General Restriction. Subject to Section 10.6, the Purchased Shares
and all securities issued in exchange therefor or upon conversion or exercise
thereof (for purposes of this Section 7, the "Restricted Securities"), will be
transferable only upon the satisfaction of the conditions set forth in this
Section 7. Any transfer or purported transfer in violation of this Section 7
will be void.

         7.2. Notice of Transfer. Subject to Section 10.6, prior to any transfer
of any Restricted Securities, the holder thereof will give written notice to the
Company describing in reasonable detail the manner and terms of the proposed
transfer and the identity of the proposed transferee, accompanied by the written
agreement of the proposed transferee to be bound by all of the provisions hereof
applicable to holders of such Restricted Securities hereunder or thereunder. The
Company may request an opinion of counsel of such holder prior to such transfer
to the effect that such transfer is exempt from the registration requirements of
the Securities Act of 1933, as amended.

subject to the restrictions on transfer set forth in this Section 7, the
certificates representing such Purchased Shares will bear restrictive legends in

         registered under the Securities Act of 1933, as amended (the
         "Securities Act"), and may be transferred only pursuant to an effective
         registration statement under the Securities Act or in accordance with

                                      -25-

         "The securities represented by this certificate are subject to certain
         restrictions on transfer set forth in a Series C Preferred Stock
         Purchase Agreement, dated as of March3, 2000, by and among the issuer
         of such securities and the registered holder of this certificate (or
         such holder's predecessor-in-interest) and certain others. A copy of
         such agreement is on file and may be inspected by the registered
         holder of this certificate at the principal executive office of the
         issuer."

         7.4. Termination of Restrictions. The restrictions imposed by this
Section 7 upon the transferability of Restricted Securities will terminate as to
any particular Restricted Securities when such Restricted Securities have been
sold pursuant to an effective registration statement under the Securities Act,
or pursuant to Rule 144 under the Securities Act or any other exemption from the
registration requirements of the Securities Act pursuant to which the transferee
receives securities that are not "restricted securities" within the meaning of
that term as defined in Rule 144(a)(3). Whenever any of such restrictions
terminates as to any Restricted Securities, the holder thereof will be entitled
to receive from the Company, at the Company's expense, new certificates
representing such Purchased Shares, without restrictive legends.

provision of this Agreement that is for the benefit of the holders of Series C
Preferred Stock may be waived (either generally or in a particular instance, and
either retroactively or prospectively), and any consent, approval, or other
action to be given or taken by the holders of Series C Preferred Stock pursuant
