         In consideration of the mutual promises, covenants and conditions
hereinafter set forth, the parties hereto mutually agree as follows:

                                   SECTION 1

                      Authorization and Sale of the Warrant

         1.1 Authorization. The Company has, or before the Closing (as
hereinafter defined) will have, authorized the sale and issuance of a stock
purchase warrant (the "Warrant") in the form attached hereto as Exhibit A for
the purchase of up to 750,000 shares (the "Warrant Shares") of Common Stock, par

         1.2 Sale and Purchase of the Warrant. Subject to the terms and
conditions hereof and in reliance upon the representations and agreements
contained herein, at the Closing the Company will issue and sell to the Investor
and the Investor will purchase from the Company, the Warrant at a purchase price
of $0.01 per Warrant Share.

                                   SECTION 2

                             Closing Date; Delivery

         2.1 Closing Date. The closing for the purchase and sale of the Warrant
(the "Closing") shall be held at the offices of Dorsey & Whitney LLP, 220 South
Sixth Street, Minneapolis, MN 55402, on January 28, 2000, at 10:00 a.m. or at
such other time and place as the Company and the Investor mutually agree upon
(the "Closing Date").

         2.2 Closing. At the Closing, the Company will deliver to the Investor
the Warrant against payment of the purchase price therefor by check payable to
the order of the Company or wire transfer.

                                   SECTION 3

                         Representations of the Company

         Subject to and except as disclosed by the Company in the Schedule of
Exceptions attached hereto as Exhibit B, the Company hereby represents to the
Investor as follows:

         3.1 Organization and Standing. The Company is a corporation duly
organized, validly existing, and in good standing under the laws of the State of
Minnesota. The Company

                                       1
<PAGE>   5


has all requisite corporate power to own and operate its properties and assets,
and to carry on its business as presently conducted and as proposed to be
conducted. The Company is qualified to do business as a foreign corporation in
each jurisdiction in which such qualification is required and where the failure
to be so qualified would have a material adverse effect on the Company's
business, results of operations or financial condition.

         3.2 Corporate Power. The Company has all requisite legal and corporate
power to execute and deliver this Agreement, to sell and issue the Warrant and
to carry out and perform its obligations under the terms of this Agreement.

         3.3 Capitalization. The authorized capital stock of the Company
consists of 100,000,000 shares of Common Stock, of which 17,001,646 shares are
issued and outstanding. All issued and outstanding shares have been duly
authorized and validly issued, and are fully paid and nonassessable. The Company
by appropriate action by the Board of Directors has reserved (or shall have
reserved prior to the Closing) the appropriate number of shares of Common Stock
for issuance upon exercise of the Warrant. The Company has reserved 8,420,000
shares of Common Stock for issuance pursuant to stock options, of which
6,766,700 shares are subject to outstanding options and of which 1,653,300
shares remain available for future issuance to employees, directors, officers,
consultants and advisors of the Company, pursuant to stock purchase or stock
options to be approved by the Company's Board of Directors.

         Except as set forth above, there are no preemptive or other outstanding
rights, options, warrants, conversion rights, understandings or agreements for
the purchase or acquisition from the Company of any shares of its capital stock
or other securities of the Company. To the best of the Company's knowledge,
there are not any agreements, understandings or arrangements among the
shareholders relating to the transfer of outstanding capital stock of the
Company.

         3.4 Authorization. All corporate action on the part of the Company, its
directors and shareholders necessary for the sale and issuance of the Warrants
and Warrant Shares and the performance of the Company's obligations hereunder
and the reservation of the Warrant Shares has been taken or will be taken prior
to the Closing. This Agreement and the Warrant are valid and binding obligations
of the Company, enforceable in accordance with their respective terms, subject
to laws of general application relating to bankruptcy, insolvency and the relief
of debtors and subject to general equity principles and to limitations on the
availability of equitable relief, including specific performance. The Warrant
Shares, when issued in compliance with the provisions of this Agreement and the
Warrant, will be validly issued and will be fully paid and nonassessable, and
will be free of any liens or encumbrances; provided, however, that the Warrant
Shares and the Underlying Stock may be subject to restrictions on transfer under
state and/or federal securities laws and as set forth herein.

         3.5 Financial Statements. The Company has delivered to the Investor its
audited financial statements (balance sheet and profit and loss statement,
statement of shareholders' equity and statement of cash flows including notes
thereto) at May 31, 1999 and for the fiscal year then ended and its unaudited
financial statements (balance sheet and profit and loss statement) as at, and
for the six-month period ended November 30, 1999 (the "Financial Statements").
The Financial Statements have been prepared in accordance with generally



                                      2
<PAGE>   6


accepted accounting principles applied on a consistent basis throughout the
periods indicated and with each other, except that unaudited Financial
Statements may not contain all footnotes required by generally accepted
accounting principles. The Financial Statements fairly present the financial
condition and operating results of the Company as of the dates, and for the
periods, indicated therein, subject in the case of the unaudited Financial
Statements to normal year-end audit adjustments. Except as set forth in the
Financial Statements, the Company has no material liabilities, contingent or
otherwise, other than (i) liabilities incurred in the ordinary course of
business subsequent to November 30, 1999 and (ii) obligations under contracts
and commitments incurred in the ordinary course of business and not required
under generally accepted accounting principles to be reflected in the Financial
Statements, which, in both cases, individually or in the aggregate, are not
material to the financial condition or operating results of the Company.

         3.6 Absence of Changes. To the Company's knowledge, since November 30,
1999, the Company has not obtained any material loss or interference with its
business from fire, explosion, flood or other calamity, whether or not covered
by insurance; and there loss has not been any material adverse change in the
business, properties, results of operations or financial condition of the
Company.

         3.7 Title to Properties and Assets; Liens, etc. The Company has good
and marketable title to all of its properties and assets, in each case subject
to no mortgage, pledge, lien, lease, encumbrance or charge, other than (i) the
lien of current taxes not yet due and payable, and (ii) possible minor liens and
encumbrances which do not in any case materially detract from the value of the
property subject thereto or materially impair the operations of the Company, and
which have not arisen otherwise than in the ordinary course of business. With
respect to the property and assets it leases, the Company is in material
compliance with such leases and, to the best of its knowledge, holds a valid
leasehold interest free of any material liens, claims or encumbrances.

         3.8 No Conflict with Other Instruments; Compliance with Laws. The
execution, delivery and performance of this Agreement and the Warrant will not
result in any violation of, be in conflict with, or constitute a default under,
with or without the passage of time or the giving of notice: (i) any provision
of the Company's Articles of Incorporation or Bylaws; (ii) any provision of any
judgment, decree or order to which the Company is a party or by which it is
bound; (iii) any material contract, obligation or commitment to which the
Company is a party or by which it is bound; or (iv) to the Company's knowledge,
any statute, rule or governmental regulation applicable to the Company.

         3.9 Patents, Trademarks and Trade Secrets. There are no pending or, to
the Company's knowledge, threatened claims against the Company alleging that the
Company's business, as conducted or as proposed to be conducted, infringes or
conflicts with the rights of others under patents, service marks, trade names,
trademarks, copyrights, trade secrets or other proprietary rights. To the
Company's knowledge, the Company's business as now conducted does not, and as
proposed to be conducted will not, infringe or conflict with the rights of
others, including rights under patents, service marks, trade names, trademarks,
copyrights, trade secrets and other proprietary rights. To the Company's
knowledge, it owns or possesses sufficient legal rights to all the patents,
copyrights, trademarks, trade names, service marks, trade secrets and



                                      3
<PAGE>   7


other rights necessary for the operation of its business as now conducted and as
proposed to be conducted without conflict or infringement against the rights of
others.

         3.10 Litigation, etc. There are no actions, suits or proceedings
pending, which questions the validity of this Agreement or the right of the
Company to enter into such agreement, or which might result, either individually
or in the aggregate, in any material adverse change in the assets, conditions or
affairs of the Company, financial or otherwise.

         3.11 Governmental Consent, etc. No consent, approval or authorization
of, or designation, declaration or filing with, any governmental authority on
the part of the Company is required in connection with the valid execution,
delivery and performance of this Agreement, or the offer, sale or issuance of
the Warrant and the Warrant Shares.

         3.12 Offering. Based in part on the representations of the Investors
set forth in Section 4 hereof, the offer, sale and issuance of the Warrant and
the Warrant Shares in conformity with the terms of this Agreement constitute
transactions exempt from the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act").

         3.13 Permits. To its knowledge, the Company has all franchises,
permits, licenses, and any similar authority necessary for the conduct of its
business as now being conducted by it, the lack of which could materially and
adversely affect the business, properties, results of operations or financial
condition of the Company. To its knowledge, the Company is not in default in any
material respect under any of such franchises, permits, licenses, or other
similar authority.

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

         3.15 Tax Returns and Payments. The Company has filed all tax returns
and reports as required by law. These returns and reports are true and correct
in all material respects. The Company has paid all taxes and other assessments
due.

any distribution thereof, and it has no present intention of selling or
distributing the Warrant or Warrant Shares. The Investor understands that the

provisions of the Securities Act which depends upon, among other things, the
bona fide nature of the investment intent as expressed herein.

         4.4 Rule 144 and Rule 144A. The Investor acknowledges that, because
they have not been registered under the Securities Act, the Warrant and Warrant

The Investor is aware of the provisions of Rule 144 and Rule 144A promulgated
under the Securities Act, which rules permit limited resale of securities
purchased in a private placement subject to the satisfaction of certain
conditions.

now exists for any of the securities issued by the Company.

         4.6 Access to Data. The Investor has received and reviewed such

concerning the purchase of the Warrant and Warrant Shares and has had an
opportunity to discuss the Company's business, management and financial affairs
with its management and to obtain any additional information necessary to verify
the accuracy of the information given to such Investor. The foregoing, however,
does not limit or modify the representations and warranties of the Company in
Section 3 of this Agreement or the right of the Investor to rely thereon.

         4.7 Legends. The Investor acknowledges and accepts that all
certificates for the Warrant and Warrant Shares shall bear restrictive legends
preventing its free transfer.

                                   SECTION 8

                              Additional Agreements

         8.1 Requested Registration. After the Company has qualified for the use
of Form S-3 under the Securities Act, Investor shall have the right to request
registrations of Warrant Shares on Form S-3 thereafter under this Section 8.1
(such requests shall be in writing and shall state the number of Warrant Shares
to be disposed of and the intended method of disposition of such shares),
provided that the Company shall not be required to effect a registration
pursuant to this Section 8.1 unless the Investor proposes to dispose of Warrant
Shares which it reasonably anticipates will have an aggregate disposition price
(before deduction of underwriting discounts and expenses of sale) of at least
one million dollars ($1,000,000), provided further that the Company shall not be
required to effect a registration pursuant to this Section 8.1 if at the time of
the request for a registration on Form S-3, the Company in good faith gives
notice within thirty (30) days of such request that it is engaged or has fixed
plans to engage within sixty (60) days of the time of the request in a firmly
underwritten registered public offering (but such notice may not be given more
than once in any six (6) month period), provided further that the Company



                                      7
<PAGE>   11


shall not be required to effect more than one registration pursuant to this
Section 8.1 in any twelve (12) month period, and provided further that the
Company shall not be required to file more than two registrations on Form S-3
with respect to Warrant Shares. Upon receipt of a proper request for
registration pursuant to this Section 8.1, the Company will as soon as
practicable but in any event within ninety (90) days, use its diligent efforts
to effect such registration (including, without limitation, the execution of an
undertaking to file post-effective amendments, appropriate qualification under
applicable blue sky or other state securities laws and appropriate compliance
with applicable regulations issued under the Securities Act) as may be so
requested and as would permit or facilitate the sale and distribution of all or
such portion of the Warrant Shares as are specified in such request provided
that the Company shall not be obligated to take any action to effect any such
registration, qualification or compliance pursuant to this Section 8.1 in any
particular jurisdiction in which the Company would be required to execute a
general consent to service of process in effecting such registration,
qualification or compliance unless the Company is already subject to service in
such jurisdiction and except as may be required by the Securities Act.

         Subject to this Section 8.1(b) and Section 8.1(d), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable after receipt of the request of the
Investor.

                  (c) Underwriting. If the Investor intends to distributed
         Warrant Shares by means of an underwriting, it shall so advise the
         Company as a part of their request made pursuant to Section 8.1.

         The Company shall together with Investor enter into an underwriting
agreement in customary form with the underwriter or underwriters selected for
such underwriting by the Company with the approval of the Investor, which
approval shall not be unreasonably withheld.

         If the Investor disapproves of the terms of the underwriting, the
Investor may elect to withdraw therefrom by written notice to the Company and
the underwriter.

         If the underwriter does not limit the number of shares of Common Stock
to be underwritten, the Company may include securities for its own account or
the account of others in such registration if the underwriter so agrees and if
the number of shares of Common Stock which would otherwise have been included in
such registration and underwriting will not thereby be limited.

                  (d) Delay of Registration. If the Company shall furnish to the
         Investor a certificate signed by the president of the Company stating
         that, in the good faith judgment of the Board of Directors of the
         Company, it would be seriously detrimental to the Company and its
         shareholders for such registration statement to be filed on or before
         the date filing would be required and it is therefore essential to
         defer the filing of such registration statement, then the Company may
         direct that such request for registration be delayed for a period not
         in excess of ninety (90) days, such right to delay a request to be
         exercised by the Company not more than once in any 180-day period.

         8.2 Company Registration.

                  (a) If at any time or from time to time, the Company shall
         determine to register any of its Common Stock, for its own account or
         for the account of others, other than a registration relating solely to
         employee benefit plans or a registration relating solely to a
         reorganization, merger or other transaction on Form S-4 (or any
         comparable or successor form or forms), the Company will:

                           (i) promptly give to the Investor written notice
                  thereof (which shall include a list of the jurisdictions in
                  which the Company intends to attempt to qualify such
                  securities under the applicable blue sky or other state
                  securities laws); and

                           (ii) include in such registration (and any related
                  qualification under blue sky laws or other compliance), and in
                  any underwriting involved therein, all Warrant Shares
                  specified in a written request or requests, made within ten
                  (10) days after receipt of such written notice from the
                  Company, by the Investor; provided that the rights set forth
                  in this Section 8.2 shall not apply to the Company's initial
                  public offering of shares of Common Stock.

                  (b) Underwriting. If the registration of which the Company
         gives notice is for a registered public offering involving an
         underwriting, the Company shall so advise the Investor as a part of the
         written notice given pursuant to Section 8.2(a)(i). In such event the
         right of the Investor to registration pursuant to Section 8.2 shall be
         conditioned upon its participation in such underwriting and the
         inclusion of its Warrant Shares in the underwriting to the extent
         provided herein. The Investor shall (together with the Company) enter
         into an underwriting agreement in customary form with the underwriter
         or underwriters selected for such underwriting by the Company.
         Notwithstanding any other provision of this Section 8.2, if the
         underwriter determines that marketing factors require a limitation of
         the number of shares to be underwritten, the underwriter may limit the
         number of Warrant Shares to be included in the registration and
         underwriting pursuant to this Section 8.2 to not less than five percent
         (5%) of the total number of shares covered by the registration. The
         Company will advise the Investor of any such limitation.

         No Warrant Shares excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration. If
the Investor disapproves of the terms of any such underwriting, the Investor may
elect to withdraw therefrom by written notice to the Company and the
underwriter. The Warrant Shares so withdrawn from such underwriting shall also
be withdrawn from such registration.

         8.3 Expenses of Registration. All registration expenses incurred in
connection with any registration pursuant to Section 8.1 and Section 8.2 shall
be borne by the Company. All selling expenses incurred in connection with any
registrations hereunder shall be borne by the Investor. The Company shall not,
however, be required to pay for expenses of any registration which subsequently
is withdrawn by the Investor, unless the withdrawal is based upon material



                                      9
<PAGE>   13


adverse information concerning the Company of which the Investor was not aware
at the time of such request, in which case such expenses shall be borne by the
Investor.

         8.4 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Article 8,
the Company will keep the Investor advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

                  (a) keep such registration, qualification or compliance
         effective for a period of one hundred twenty (120) days or until the
         Investor has completed the distribution described in the registration
         statement relating thereto, whichever first occurs; and

                  (b) furnish such number of prospectuses and other documents
         incident thereto as the Investor from time to time may reasonably
         request.

         8.5 Indemnification

                  (a) The Company will indemnify the Investor, each of its
         officers, directors, and partners, and each person controlling the
         Investor within the meaning of the Securities Act, with respect to
         which registration, qualification or compliance has been effected
         pursuant to this Article 8, against all claims, losses, damages and
         liabilities (or actions in respect thereof) arising out of or based on
         (i) any untrue statement (or alleged untrue statement) of a material
         fact contained in any prospectus, offering circular or other similar
         document (including any related registration statement, notification or
         the like) incident to any such registration, qualification or
         compliance, or based on any omission (or alleged omission) to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein not misleading in the light of the
         circumstances under which they were made, or (ii) any violation by the
         Company of any federal, state or common law rule or regulation
         applicable to the Company in connection with any such registration,
         qualification or compliance, and will reimburse the Investor, each of
         its officers, directors, partners and legal counsel, and each person
         controlling the Investor, for any legal and any other expenses
         reasonably incurred in connection with investigating or defending any
         such claim, loss, damage, liability or action, as incurred, provided
         that the Company will not be liable in any such case to the extent that
         any such claim, loss, damage, liability or expense arises out of or is
         based on any untrue statement or omission based upon written
         information furnished to the Company by the Investor and stated to be
         specifically for use therein or furnished by the Investor to the
         Company in response to a request by the Company stating specifically
         that such information will be used by the Company therein.

                  (b) The Investor will indemnify the Company, each of its
         directors and officers, each legal counsel and independent accountant
         of the Company, each person who controls the Company within the meaning
         of the Securities Act, against all claims, losses, damages and
         liabilities (or actions in respect thereof) arising out of or based on
         any untrue statement (or alleged untrue statement) of a material fact
         contained in any such registration statement, prospectus, offering
         circular or other similar document, or any omission (or alleged
         omission) to state therein a material fact required to be stated



                                     10
<PAGE>   14


         therein or necessary to make the statements therein not misleading in
         the light of the circumstances under which they were made, and will
         reimburse the Company, such directors, officers, persons, or control
         persons for any legal or any other expenses reasonably incurred in
         connection with investigating or defending any such claim, loss,
         damage, liability or action, as incurred, in each case to the extent,
         but only to the extent, that such untrue statement (or alleged untrue
         statement) or omission (or alleged omission) is made in such
         registration statement, prospectus, offering circular or other document
         in reliance upon and in conformity with written information furnished
         to the Company by the Investor and stated to be specifically for use
         therein or furnished by the Investor to the Company in response to a
         request by the Company stating specifically that such information will
         be used by the Company therein; provided, however, that the obligations
         of the Investor hereunder shall be limited to an amount equal to the
         proceeds to each the Investor of Warrant Shares sold as contemplated
         herein.

                  (c) Each party entitled to indemnification under this Section
         8.5 (the "Indemnified Party") shall give notice to the party required
         to provide indemnification (the "Indemnifying Party") promptly after
         such Indemnified Party has received written notice of any claim as to
         which indemnity may be sought, and shall permit the Indemnifying Party
         to assume the defense of any such claim or any litigation resulting
         therefrom, provided that counsel for the Indemnifying Party, who shall
         conduct the defense of such claim or litigation, shall be approved by
         the Indemnified Party (whose approval shall not unreasonably be
         withheld). The Indemnified Party may participate in such defense at
         such party's expense; provided, however, that the Indemnifying Party
         shall bear the expense of such defense of the Indemnified Party if
         representation of both parties by the same counsel would be
         inappropriate due to actual or potential conflicts of interest. The
         failure of any Indemnified Party to give notice within a reasonable
         period of time as provided herein shall relieve the Indemnifying Party
         of its obligations under this Section 8.5 only to the extent that such
         failure to give notice shall materially adversely prejudice the
         Indemnifying Party in the defense of any such claim or any such
         litigation and any such failure to give notice shall not relieve the
         Indemnifying Party of any liability that it may have to any Indemnified
         Party otherwise than under this Section 8.5. No Indemnifying Party, in
         the defense of any such claim or litigation, shall, except with the
         consent of each Indemnified Party, consent to entry of any judgment or
         enter into any settlement which does not include as an unconditional
         term thereof the giving by the claimant or plaintiff to such
         Indemnified Party of a release from all liability in respect to such
         claim or litigation.

                  (d) If the indemnification provided for paragraphs (a) through
         (c) of this Section 8.5 is unavailable or insufficient to hold harmless
         an Indemnified Party under such paragraphs in respect of any losses,
         claims, damages or liabilities or actions in respect thereof referred
         to therein, then each Indemnifying Party shall in lieu of indemnifying
         such Indemnified Party contribute to the amount paid or payable by such
         Indemnified Party as a result of such losses, claims, damages,
         liabilities or actions in such proportion as appropriate to reflect the
         relative fault of the Company, on the one hand, and the underwriters
         and the Investor, on the other, in connection with the statements or
         omissions which resulted in such losses, claims, damages, liabilities
         or actions as well as any other relevant equitable considerations. The
         relative fault shall be determined by



                                      11
<PAGE>   15


         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact relates to information supplied by the
         Company, on the one hand, or the underwriters or the Investor, on the
         other, and to the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such statement or
         omission. The Company and the Investor agree that it would not be just
         and equitable if contributions pursuant to this paragraph were
         determined by pro rata allocation or by any other method of allocation
         which did not take account of the equitable considerations referred to
         above in this paragraph. The amount paid or payable by an Indemnified
         Party as a result of the losses, claims, damages, liabilities or action
         in respect thereof, referred to above in this paragraph, 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
         paragraph, the Investor shall not be required to contribute any amount
         in excess of the lesser of (i) the proportion that the public offering
         price of shares sold by the Investor under such registration statement
         bears to the total public offering price of all securities sold
         thereunder, but not to exceed the proceeds received by the Investor for
         the sale of Warrant Shares covered by such registration statement and
         (ii) the amount of any damages which they would have otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission. No person guilty of fraudulent misrepresentations (within the
         meaning of Section 11(f) of the Securities Act), shall be entitled to
         contribution from any person who is not guilty of such fraudulent
         misrepresentation.

                  (e) Notwithstanding the foregoing, to the extent that the
         provisions on indemnification and contribution contained in the
         underwriting agreement entered into in connection with the underwritten
         public offering are in conflict with the foregoing provisions, the
         provisions in the underwriting agreement shall control.

                  (f) The obligations of the Company and the Investor under this
         Section 8.5 shall survive the completion of any offering of Registrable
         Securities in a registration statement under this Article 8, and
         otherwise.

         8.6 Information by the Investor. The Investor shall furnish to the
Company such information regarding the Investor and the distribution proposed by
the Investor as the Company may request in writing and as shall be required in
connection with any registration, qualification or compliance referred to in
this Article 8.

         8.7 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Warrant Shares to the public without registration, after such time
as a public market exists for the Common Stock of the Company, the Company
agrees to at all times after ninety (90) days after the effective date of the
first registration under the Securities Act filed by the Company for an offering
of its securities to the general public:

                  (a) facilitate the sale of the Warrant Shares to the public,
         without registration under the Securities Act, pursuant to Rule 144
         under the Securities Act, provided that this shall not require the
         Company to file reports under the Securities Act and the Securities



                                       12
<PAGE>   16



         Exchange Act of 1934 as amended (the "Exchange Act") at any time prior
         to the Company's being otherwise required to file such reports.

                  (b) make and keep public information available, as those terms
         are understood and defined in Rule 144 under the Securities Act;

                  (c) file with the Commission in a timely manner all reports
         and other documents required of the Company under the Securities Act
         and the Exchange Act, (at any time after it has become subject to such
         reporting requirements); and

                  (d) so long as the Investor owns the Warrant or Warrant Shares
         to furnish to the Investor forthwith upon request a written statement
         by the Company as to its compliance with the reporting requirements of
         said Rule 144, and of the Securities Act and the Exchange Act (at any
         time after it has become subject to such reporting requirements), a
         copy of the most recent annual or quarterly report of the Company, and
         such other reports and documents so filed by the Company as the
         Investor may reasonably request in availing itself of any rule or
         regulation of the Commission allowing the Investor to sell any such
         securities without registration.

         8.8 "Market Stand-off" Agreement. The Investor agrees not to sell or
otherwise transfer or dispose of any Common Stock (or other securities) of the
Company held by it for a period not to exceed one hundred eighty (180) days
following the effective date of a registration statement of the Company filed
under the Securities Act if so requested by the Company and underwriter of
Common Stock (or other securities) of the Company, provided that:

                  (a) such agreement shall apply only to the first underwritten
         registered public offering of the Company; and

                  (b) such agreement shall not apply to securities included in
         such registration statement pursuant to Section 8.2.

         8.9 Termination of Registration Rights. All rights and duties provided
for in this Section 8 shall terminate, at such time as the Investor is able to
dispose of all of his Registrable Securities in one three-month period pursuant
to the provisions of Rule 144.

         8.10 Right of First Refusal. The Company is hereby granted the right of
first refusal (the "First Refusal Right"), exercisable in connection with any
proposed sale or other transfer of the Warrant or any Warrant Shares. For
purposes of the First Refusal Right, the term "transfer" shall include any
assignment, pledge, encumbrance or other disposition for value of the Warrant or
Warrant Shares intended to be made by the Investor.

         8.11 Notice of Intended Disposition. In the event the Investor desires
to accept a bona fide third-party offer for the Warrant or any or all of the
Warrant Shares (the Warrant or Warrant shares subject to such offer to be
hereinafter called, solely for the purposes of the First Refusal Right, the
"Target Shares"), the Investor shall promptly (i) deliver to the Secretary of
the Company written notice (the "Disposition Notice") of the offer and the basic
terms and conditions thereof, including the proposed purchase price, and (ii)
provide satisfactory proof that



                                       13
<PAGE>   17


the disposition of the Target Shares to the third-party offeror would not be in
contravention of the provisions set forth in this Agreement and the Warrant.

         8.12 Exercise of Right The Company (or its assignees) shall, for the
period of ten (10) business days following receipt of the Disposition Notice,
have the right to repurchase all of the Target Shares specified in the
Disposition Notice upon substantially the same terms and conditions specified
therein. Such right shall be exercisable by written notice (the "Exercise
Notice") delivered to the Investor prior to the expiration of the ten (10)
business day exercise period. If such right is exercised, then the Company (or
its assignees) shall effect the repurchase of the Target Shares, including
payment of the purchase price, not more than five (5) business days after
delivery of the Exercise Notice; and at such time the Investor shall deliver to
the Company the certificates representing the Target Shares to be repurchased,
each certificate to be properly endorsed for transfer.

         Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the Company
(or its assignees) shall have the right to pay the purchase price in the form of
cash equal in amount to the value of such property. As determined in good faith
by the Company's board of directors.

         8.13 Non-Exercise of Right. In the event the Exercise Notice is not
given to the Investor within ten (10) business days following the date of the
Company's receipt of the Disposition Notice, the Investor shall have a period of
thirty (30) days thereafter in which to sell or otherwise dispose of the Target
Shares upon terms and conditions (including the purchase price) no more
favorable to the third-party purchaser than those specified in the Disposition
Notice; provided, however, that any such sale or disposition must not be
effected in contravention of the provisions of this Agreement and the Warrant.
The third-party purchaser shall acquire the Target Shares free and clear of all
the terms and provisions of this Agreement. In the event the Investor does not
sell or otherwise dispose of the Target Shares within the specified thirty-(30)
day period, the Company's First Refusal Right shall continue to be applicable to
any subsequent disposition of the Target Shares by the Investor until such right
lapses in accordance with Section 8.16.

         8.14 Recapitalization. In the event of any stock dividend, stock split,
recapitalization or other transaction affecting the Company's outstanding common
stock as a class effected without receipt of consideration, then any new,
substituted or additional securities or other property which is by reason of
such transaction distributed with respect to the Warrant Shares shall be
immediately subject to the Company's First Refusal Right hereunder, but only to
the extent the Warrant Shares are at that time covered by such right.

         8.15 Lapse. The First Refusal Right shall lapse and cease to have
effect upon a firm commitment underwritten public offering pursuant to an
effective registration statement under the Securities Act.
