                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company hereby represents and warrants to the Investor as follows:

         3.1. Organization and Standing; Articles of Incorporation and Bylaws.
The Company is a corporation duly organized and validly existing under, and by
virtue of, the laws of the State of Minnesota and is in good standing under such
laws. The Company is qualified to do business as a foreign corporation in every
jurisdiction in which the failure to so qualify would have a material adverse
effect on the business, assets, operating results, prospects or financial
condition of the Company (a "Material Adverse Effect"). The Company has the
requisite corporate power and authority 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 has previously delivered to the Investor true and
accurate copies of the Restated Articles of Incorporation and Bylaws, as
presently in effect, of the Company.

         3.2. Corporate Power. The Company has all requisite legal and corporate
power and authority to enter into this Agreement and the Registration Rights

Note Shares.

         3.3. Subsidiaries and Affiliates. Except as set forth on Schedule 3.3,
the Company does not own or control, directly or indirectly, any interest or
investment in any corporation, partnership, association or other form of

shall include references to the subsidiaries listed on Schedule 3.3, unless the
context requires otherwise.

         3.4. Capitalization. The authorized capital stock of the Company
consists of 8,333,333 shares of Common Stock, $.01 par value, 4,537,028 shares
of which are issued and outstanding as of June 30, 2000, and 333,333 shares of
preferred stock, of which 40,000 shares have been issued as Series A 8%
Convertible Preferred Stock (the "Series A Preferred Stock") and are outstanding
as of June 30, 2000,. All such issued and outstanding shares have been duly
authorized and validly issued, are fully paid and non-assessable, and have been
offered, issued, sold and delivered by the Company in compliance with applicable
federal and state securities laws. Except as set forth in Schedule 3.4 attached
hereto, there are no outstanding rights, options, warrants, conversion rights or
agreements for the purchase or acquisition from the Company of any shares of its
capital stock or other securities other than rights created by this Agreement.

         3.5. Authorization. All corporate action on the part of the Company and
its directors, officers and shareholders necessary for the authorization,
execution, delivery and performance of all obligations of the Company under the
Transaction Documents and any document contemplated hereby, for the
authorization, issuance and delivery of the Purchased Shares, has been (or will
be) taken prior to the Closings with respect to issuance of the Purchased Shares
and/or Note Shares issued by the Company at the Closings. The Agreement
constitutes a valid and binding obligation of the Company and are enforceable
against the Company in accordance with their terms, except as enforceability may
be limited by bankruptcy, insolvency or other laws

                                      -3-
<PAGE>

affecting the enforcement of creditors' rights generally, and except that the
availability of the remedy of specific performance or other equitable relief is
subject to the discretion of the court before which any proceeding therefor may
be brought.

         3.6. Validity of Stock. The Purchased Shares and the Note Shares, when
issued, sold and delivered in compliance with the provisions of this Agreement
and will be validly issued, fully paid and nonassessable, will be free of any
liens or encumbrances, and will not be subject to any preemptive rights, rights
of first refusal or redemption rights, other than as provided herein and in the
Restated Articles of Incorporation and the Bylaws (the "Bylaws") of the Company.
The Purchased Shares and the Note Shares are not subject to any preemptive
rights or rights of first refusal or redemption rights (other than as provided
herein and in the Restated Articles of Incorporation and the Bylaws) and, upon
issuance, will be validly issued, fully paid and non-assessable.

         3.7. Material Liabilities. Except as disclosed on Schedule 3.7 attached
hereto, the Company has no liabilities or obligations, absolute or contingent
(individually or in the aggregate), except obligations and liabilities incurred
in the ordinary course of business that are not individually or in the aggregate
material to the Company.

         3.8. Contracts and Commitments. Except as disclosed on Schedule 3.8,
other than this Agreement, the Company has no contracts, agreements or
instruments to which it is a party and that involve a commitment by, or revenue
to, the Company in excess of $20,000 annually. All contracts, agreements or
instruments to which the Company is a party are valid and binding upon the
Company and, to best knowledge and belief of the Company, the other parties
thereto, and are in full force and effect and enforceable in accordance with
their terms. Neither the Company nor, to best knowledge and belief of the
Company, any other party to any such contract, agreement or instrument, has
breached any provision of, or is in default under, the terms thereof, and, there
are no existing facts or circumstances that would prevent the work in process of
the Company or its contracts and agreements from maturing in due course into
fully collectible accounts receivable.

         3.9. Intellectual Property Rights. Schedule 3.9 hereto sets forth a
complete and correct list of (i) all patents (the "Patents"), trademarks, trade
names (including all federal and state registration pertaining thereto) and
registered copyrights owned by the Company or any subsidiary of the Company
(collectively, the "Proprietary Intellectual Property") and (ii) all patents,
trademarks, trade names, copyrights, technology and processes used by the
Company or any subsidiary of the Company in their businesses which are material
to their businesses and are used pursuant to a license or other right granted by
a third party (collectively, the "Licensed Intellectual Property," and together
with the Proprietary Intellectual Property referred to as "Intellectual
Property"). A true and complete list of all such licenses and agreements with
respect to Licensed Intellectual Property is set forth in Schedule 3.9. Each of
the federal, state and other governmental registrations with any country
pertaining to the Proprietary Intellectual Property is valid and in full force
and effect. The Company owns, or has the right to use pursuant to valid and
effective agreements, all Intellectual Property, and the consummation of the
transactions contemplated hereby will not materially adversely alter or impair
any such rights. No claims are pending against the Company by any person with
respect to the use of any

                                       -4-
<PAGE>

Intellectual Property or challenging or questioning the validity or
effectiveness of any license or agreement relating to the same that would be
likely to result in a Material Adverse Effect, and the current use by the
Company of the Intellectual Property does not in any material respect infringe
upon the rights of any third party. Schedule 3.9 sets forth a list of all
jurisdictions in which the Company is operating under a trade name, and each
jurisdiction in which any such trade name is registered. No Patent has been or
is now involved in any interference, reissue, reexamination or opposition
proceeding, nor is the Company aware of any potentially interfering patent or
patent application of any third party. To the knowledge of the Company, no
person or entity is presently selling or marketing a product which is covered by
the Patents, and the Patents have not been challenged or threatened in any way.
Further, no current or former Company employee is named as an inventor on any
pending patent application. All the Patents are currently in compliance with
formal legal requirements (including payment of filing, examination and
maintenance fees and proofs of working or use), and to the best knowledge of the
Company, there is nothing which would render the Patents invalid or
unenforceable, and they are not subject to any maintenance fees or taxes or
actions falling due within ninety days after the date of Closing.

         3.10. Company Computer Software and Hardware.

               (a) Schedule 3.10(a) hereto sets forth a true and complete list
as of June 30, 2000 of: (a) all software and associated documentation owned by
the Company material to the business of the Company, other than custom-developed
software developed for and assigned to a Company customer, owned by the Company,
(such items set forth on Schedule 3.10(a) together with all software and
associated documentation material to the business of the Company developed by
the Company since the date of its incorporation are hereinafter referred to as
the "Company Proprietary Software"); (b) all software (other than the Company
Proprietary Software and "shrink-wrap" software) used in connection with the
business of the Company (the "Company Licensed Software" and together with the
Company Proprietary Software, the "Company Software"). Subject to any
limitations described in Schedule 3.10(a), the Company has all rights that are
necessary or appropriate to distribute, license or sublicense the Company
Software to third parties and to appoint others to do any of the foregoing.
Except as described in Schedule 3.10(a) the Company has all technical and
descriptive materials to run its business in accordance with its historical
practices, except as would not have a Material Adverse Effect. The Company
Proprietary Software consists of: (a) source and object code embodied in
magnetic media; and (b) all development and procedural tools, documentation, and
manuals necessary to maintain, enhance, develop derivative works, support and
service the Company Proprietary Software, including licenses to use compilers,
assemblers, libraries and other aids.

               (b) The Company has a valid right, title and interest in and to
all intellectual property rights in the Company Proprietary Software, including
all worldwide copyrights, trade secrets, trademarks, moral rights, and
proprietary and confidential information rights therein. The Company Proprietary
Software is free and clear of all liens, claims and encumbrances, except as
noted in Schedule 3.10(b). The use of the Company Licensed Software and the use
and distribution of the Company Proprietary Software does not breach any terms
of any contract or agreement and is in compliance with all applicable laws,
regulations and codes of any foreign, U.S., state or local authority, including
without limitation, all U.S. Export Administration

                                       -5-
<PAGE>

Regulations. The Company has been granted under the license agreements relating
to the Company Licensed Software (the "Company License Agreements") valid and
subsisting license rights with respect to all software comprising the Company
Licensed Software. The Company is in compliance with each of the terms and
conditions of each of the Company License Agreements except to the extent
failure to so comply, individually or in the aggregate, would not have a
Material Adverse Effect. To the knowledge of the Company, in the case of any
commercially available "shrink-wrap" software programs (such as Lotus 1-2-3 or
Microsoft Word), the Company has not made and is not using any unauthorized
copies of any such software programs and, to the knowledge of the Company, none
of the employees, agents or representatives of the Company have made or are
using any such unauthorized copies, except as would not have a Material Adverse
Effect.

               (c) The Company Proprietary Software and, to the best knowledge
and belief of the Company, the Company Licensed Software does not infringe the
patent, copyright, or trade secret rights or any other intellectual property
right of any third party which may exist anywhere in the world.

               (d) Except as set forth in Schedule 3.10(d), the Company has not
granted rights in the Company Software to any third party except for rights
granted to customers in the ordinary course of business pursuant to contracts
with customers.

               (e) To the knowledge of the Company, the Company Software and the
related computer hardware used by the Company in its operations (the "Company
Hardware") are adequate in all material respects, when taken together with the
other assets, resources and personnel of the Company, to run the business of the
Company in the same manner as such business has operated, except as would not
result in a Material Adverse Effect. Schedule 3.10(e) contains a summary
description of any problems experienced by the Company in the past six months
with respect to the Company Software or Company Hardware and the provision of
services to Company clients which have arisen outside the ordinary course of
business and would result in a Material Adverse Effect.

               (f) To the knowledge of the Company, the Software is "Millennium
Compliant" (defined below). For the purposes of this Agreement "Millennium
Compliant" means:

                   (i) the functions, calculations, and other computing
processes of the Software (collectively, "Processes") perform in a consistent
manner regardless of the date in time on which the Processes are actually
performed and regardless of the date input to the Software, whether before, on,
or after January 1, 2000 and whether or not the dates are affected by leap
years;

                   (ii) the Company Software accepts, calculates, compares,
sorts, extracts, sequences, and otherwise processes date inputs and date values,
and returns and displays date values, in a consistent manner regardless of the
dates used, whether before, on, or after January 1, 2000;

                                      -6-
<PAGE>

                   (iii) the Company Software will function without
interruptions caused by the date in time on which the Processes are actually
performed or by the date input to the Software, whether before, on, or after
January 1, 2000;

                   (iv) the Company Software accepts and responds to two-digit
year-date input in a manner that resolves any ambiguities as to the century in a
defined, predetermined, and appropriate manner; and

                   (v) the Company Software stores and displays date information
in ways that are unambiguous as to the determination of the century.

         3.11. Compliance with Other Instruments. The Company is not in
violation of any term of its Restated Articles of Incorporation or Bylaws or any
provision of any mortgage, indenture, contract, agreement or instrument to which
it is a party or by which it or its assets are bound; any judgment, decree or
order binding upon the Company; or, in any material respect, any statute, rule
or regulation applicable to the Company. The execution, delivery and performance
of and compliance with the Transaction Documents, the issuance of the Purchased
Shares and the Note Shares on the terms set forth in this Agreement will not
result in any such violation or be in conflict with or constitute a default
under any of the terms or provisions described in the first sentence of this
section, or result in the creation of any mortgage, pledge, lien, encumbrance or
charge upon any of the properties or assets of the Company pursuant to any such
term or provision. There is no such provision that materially and adversely
affects the business, financial condition, affairs, operations, properties or
assets of the Company taken as a whole. To the knowledge of the Company, no
employee of the Company is in violation of any term of any employment contract,
patent or trade secret disclosure agreement or any other contract or agreement,
by reason of such person's employment by the Company and the nature of the
business conducted or to be conducted by the Company.

         3.12. Litigation and Other Proceedings. Except as disclosed on Schedule
3.12 attached hereto, there are no actions, proceedings or investigations
pending against the Company, or its respective properties (or any basis therefor
or, to the Company's knowledge, threat thereof) that, either in any case or in
the aggregate, might result in any Material Adverse Effect or in any material
impairment of the right or ability of the Company to carry on its business as
now conducted or as proposed to be conducted, or in any material liability on
the part of the Company, and none that challenges the validity of this Agreement
or any action taken or to be taken in connection herewith. The foregoing
includes, without limiting its generality, actions pending or, to the knowledge
of the Company, threatened (or any threat thereof) involving the prior
employment of any of the Company's employees, or their use in connection with
the Company's business of any information or techniques allegedly proprietary to
any former employers.

         3.13. Employees. Except as disclosed on Schedule 3.13 attached hereto,
the Company has no employment contracts with any of its employees not expressly
terminable at will, and has no collective bargaining agreements covering any of
its employees. The Company is not aware of any proposed, threatened or actual
union organization activity affecting the Company's current or prospective
operations.

                                      -7-

         3.14. Registration Rights. Except as disclosed on Schedule 3.14
attached hereto, and except as provided for in the Registration Rights
Agreement, the Company is under no obligation to register any of its presently
outstanding securities or any of its securities that may hereafter be issued
pursuant to this or any other existing agreement.

         3.15. Governmental Consents. No consent, approval or authorization of,
or registration, declaration, designation, qualification or filing with, any
governmental authority on the part of the Company, other than the Shareholder
Approval and the filing of the Certificate of Amendment, is required in
connection with the valid execution and delivery of the Transaction Documents,
the offer, sale or issuance of the Purchased Shares and the Note Shares, or the
consummation of any other transaction contemplated hereby other than as provided
by applicable securities laws.

         3.16. Title to Property and Assets. Except as disclosed on Schedule
3.16 attached hereto, the Company has good and marketable title to its
respective properties and assets and has good title to all its leasehold
interests, in each case subject to no mortgage, pledge, lien, lease, encumbrance
or charge.

         3.17. Customers and Suppliers. As of June 30, 2000, the Company has no
knowledge that any customer or supplier of the Company has taken or contemplates
taking any steps that could disrupt the business relationship of the Company
with such customer or supplier or could result in a diminution in the value of
the Company, in either case in a manner that would have a material adverse
effect on business or financial condition of the Company.

         3.18. Minute Books. The minute books of the Company provided to the
Investor contain a materially complete summary of all meetings of directors and
shareholders since January 1, 1998, and reflect all transactions referred to in
such minutes accurately in all material respects.

         3.19. Licenses and Permits; Compliance with Law. The Company holds all
licenses, certificates, permits, franchises and rights from all appropriate
federal, state or other public authorities necessary for the conduct of its
business and the use of its assets. The Company is presently conducting its
business so as to comply in all material respects with all applicable statutes,
ordinances, rules, regulations and orders of any governmental authority.
Further, the Company is not presently charged with or, to the knowledge of the
Company, under governmental investigation with respect to, any actual or alleged
violation of any statute, ordinance, rule or regulation. The Company is not
presently the subject of any pending or, to the Company's knowledge, threatened
adverse proceeding by any regulatory authority having jurisdiction over its
business, properties or operations. None of the execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby will
result in the termination of any such license, certificate, permit, franchise or
right held by the Company.

         3.20. Employment; No Conflicting Agreements. None of the officers,
directors, or key employees of the Company are obligated under any contract
(including licenses, covenants, or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would conflict with his or her obligation to use his
or her

                                      -8-
<PAGE>

best efforts to promote the interests of the Company or that would conflict with
the business of the Company as presently, or proposed to be, conducted.

         3.21. Indebtedness to Directors and Officers. Except as disclosed on
Schedule 3.21, the Company is not indebted to any of its directors or officers
or party to any contract with any affiliate of its directors or officers, and,
to the knowledge of the Company, none of such directors or officers has a claim
of any nature against the Company.

         3.22. Disclosure. No representation or warranty by the Company in the
Transaction Documents or in any written statement or certificate furnished to
the Investor in connection with the transactions contemplated by the Transaction
Documents contains, or will contain, any untrue statement of a material fact or

of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
covering employees (or former employees) employed in the United States,
maintained or contributed to by the Company or any ERISA Affiliate (as
hereinafter defined), or to which the Company or any ERISA Affiliate contributes
or is obligated to make payments thereunder or otherwise may have any liability
("Pension Benefit Plans"). For purposes of this Agreement, "ERISA Affiliate"

compensation or other benefits to employees and former employees, including all
stock bonus, stock option, restricted stock, stock appreciation right, stock
purchase, bonus, incentive, deferred compensation, severance and vacation plans

each Welfare Plan, the Company has delivered or made available to the Investor
true, complete and correct copies of each Welfare Plan, insurance contract,
summary plan description, plan document, ADP/ACP test reports and Form 5500
filings for the past three (3) reporting years. Each Welfare Plan has been

                                      -10-
<PAGE>

the applicable provisions of ERISA and the Code. With respect to any Welfare
Plan that is an employee welfare benefit plan (as defined in Section 3(1) of
ERISA), no such Welfare Plan provides benefits including death or medical
benefits beyond termination of employment or retirement, except as otherwise
required by law, and each Welfare Plan may be amended or terminated without
liability at any time by the Company. To the extent required, the Welfare Plans
have complied with the continuation coverage requirements of Sections 601
through 609 of ERISA and Sections 162(k) and 4980B of the Code and with the
notice and coverage certification requirements of Section 701 of ERISA and
Section 9801 of the Code with respect to all employees, their dependents and
beneficiaries. During the last five years, to the Company's knowledge, there has

meaning of Section 406 of ERISA and Section 4975 of the Code that was not
otherwise exempt from the provisions thereof.

contribute, and neither has ever been required to contribute, to any
multi-employer plan within the meaning of Section 3(37)(A) of ERISA. Neither the
Company nor any ERISA Affiliate has ever withdrawn (in a partial or complete
withdrawal) from or incurred any liability (including any contingent liability
under Section 4204 of ERISA) with respect to any such multi-employer plan
covering employees (or former employees) employed in the United States.

or quotation of its Common Stock, and such Common Stock is currently listed or
quoted on the Nasdaq SmallCap Market.

(as defined in Rule 501 of Regulation D), and the Investor has such experience

instrument or agreement to which the Investor is a party or is subject, or by

sell, assign, transfer, pledge, encumber, hypothecate or otherwise dispose of
any Common Stock in the absence of an effective registration statement,
qualification or authorization relating thereto under federal and applicable
state securities laws or an opinion of qualified counsel satisfactory to the
Company to the effect that the proposed transaction will neither constitute or
result in any violation of the federal or state securities laws. Subject to
Section 7.3 of this Agreement, any certificate or other document that may be
issued representing any shares of Common Stock may be endorsed with a legend to
this effect.

election to the Board of Directors, which number shall increase to three
individuals upon the 2nd Closing (the "Additional Investor Designee", together
with the Initial Investor Designees, the "Investor Designees"). As promptly as
practicable after the 1st Closing, the Company shall use its best efforts to
obtain the resignation of one current member of the Board of Directors and cause
the nomination and election to the two vacant director positions the Initial
Investor Designees. Upon the 2nd Closing, the Company shall use its best efforts
to obtain the resignation one member of the Board of Directors, which member
shall not be an Investor Designee, and cause the nomination and election of the
Additional Investor Designee to the vacant director position thereby created,
and at the next annual or special meeting of stockholders of the Company held
for the purpose of electing directors, the Company shall use its best efforts to
cause the nomination and election of the Investor Designees. In connection
therewith, the Company agrees to solicit proxies for, and recommend that its
stockholders vote in favor of, the Investor Designees. If an Investor Designee
shall cease to be a member of the Board of Directors for any reason other than
expiration of his or her term, the Company shall promptly, upon the request of
the Investor, use its best efforts to cause the election or appointment of a
person selected by the Investor to replace such designee.

         7.9. Full Access. From the date hereof to the earlier of December 31,
2000 or the 2nd Closing, the Investor may, through its employees, agents and
representatives, make or cause to be made such investigation of the Company as
the Investor deems necessary or advisable and shall have full access to the
auditors and attorneys of the Company. The Company shall permit the Investor and
its employees, agents and representatives, on reasonable notice, to have access
during normal business hours to its premises, personnel and books and records.
The Company shall cooperate to provide access to its customers, clients,
suppliers, lenders and such other parties as the Investor may reasonably
request. The Company shall, and shall cause its officers, attorneys and
accountants to furnish the Investor with such financial and operating data and
other information as the Investor from time to time shall reasonably request. No
investigation by the Investor shall in any way affect or otherwise diminish the
representations, warranties and covenants of the Company hereunder.

         7.10. Restrictions Pending the 2nd Closing. The Company shall not, at
any time after the date hereof, and prior to the earlier of December 31, 2000 or

discharged, when due and payable, all lawful taxes, assessments and governmental

levies forthwith upon the commencement of proceedings to foreclose any lien that
may have attached as security therefor;

               (b) promptly pay, or cause to be paid, when due, in conformance

and correct entries will be made of all dealings or transactions in relation to
its business and affairs in accordance with generally accepted accounting

               (g) duly observe and conform to, and cause its subsidiaries, if

exceeds the compensation customarily paid to management in companies of similar

compensation for any officer or senior manager other than such changes as are
approved by a majority of the disinterested members of the Board of Directors or
any compensation committee thereof;

               (f) enter into any transaction, including, without limitation,

or obligate itself to issue, any additional shares of any class or series of
capital stock of the Company or any obligation or security exercisable for,

                                  ARTICLE VIII
                                 INDEMNIFICATION

         8.1. Obligation to Indemnify. Subject to the limitations set forth in
this Article VIII, each party hereto shall indemnify and hold the other party
harmless from and against any and all losses, claims, damages, expenses or
liabilities (including, without limitation, the costs of any investigation or
suit and counsel fees related thereto) ("Damages") asserted against, imposed
upon or incurred by such other party resulting from a breach by the indemnifying
party of any of its representations, warranties or covenants made in the
Transaction Documents or from any misrepresentation in or omission from any
certificate or other instrument furnished or to be furnished pursuant to the
Transaction Documents.

         8.2. General Indemnification Procedures.

              (a) A party seeking indemnification pursuant to Section 8.1 (an
"Indemnified Party") shall give prompt notice to the party from whom such
indemnification is sought (the "Indemnifying Party") of the assertion of any
indemnifiable claim for Damages or the commencement of any action, suit or
proceeding, in respect of which indemnity may be sought hereunder and will give
the Indemnifying Party such information with respect thereto as the Indemnifying
Party may reasonably request, but failure to give such notice shall not relieve
the Indemnifying Party of any liability hereunder (except to the extent that the
Indemnifying Party has suffered actual prejudice thereby). If any Indemnifying
Party shall be obligated to indemnify an Indemnified Party hereunder, such
Indemnifying Party shall pay to such Indemnified Party the amount to which such
Indemnified Party shall be entitled.

                                      -22-
<PAGE>

              (b) The Indemnifying Party shall have the right exercisable by
written notice to the Indemnified Party within fifteen (15) days of receipt of
notice from the Indemnified Party of the commencement of or assertion of any
claim or action, suit or proceeding by a person not a party to this Agreement
(other than an Affiliate (as defined in Section 9.3) of any party hereto) in
respect of which indemnity may be sought hereunder (a "Third Party Claim"), to
assume the defense and control the settlement of such Third Party Claim. The
Indemnifying Party or the Indemnified Party, as the case may be, shall have the
right to participate in (but not control), at its own expense, the defense of
any Third Party Claim which the other is defending as provided in this
Agreement. The Indemnifying Party, if it shall have assumed the defense of any
Third Party Claim as provided in this Agreement, shall not consent to a
settlement of, or the entry of any judgment arising from, any such Third Party
Claim without the prior written consent of the Indemnified Party (which consent
shall not be unreasonably withheld or delayed).

              (c) No action or claim for indemnification under Section 8.1
arising out of or resulting from a breach of representations and warranties
contained in Articles III and IV herein shall be brought or made until such time
as all indemnifiable claims of a party exceed $20,000 or after the period
concluding on the third anniversary of the Closing Date (the "Expiration Date");
provided, however, that the foregoing time limitations shall not apply to: (i)
any of the representations and warranties contained in Sections 3.2, 3.4, 3.5
and 3.6., each of which shall survive indefinitely; (ii) any such claims that
have been the subject of a good faith written notice from the Indemnified Party
to the Indemnifying Party, prior to the Expiration Date, which notice specifies
in reasonable detail the nature and basis for such claim (which shall survive
until the final resolution of such claim), or (iii) the warranties and
representations set forth in Section 3.23 hereof, which shall survive until such
time as the limitations period has run for all tax periods ended prior to the
Closing Dates, which shall be deemed to be the Expiration Date for Section 3.23.

                                   ARTICLE IX
                                  MISCELLANEOUS

         9.1. Governing Law. This Agreement shall be governed by and construed
under the laws of the State of Georgia.

         9.2. Survival. The representations, warranties, covenants and
agreements made herein shall survive any investigation made by the Investor and
the closings of the transactions contemplated hereby.

         9.3. Successors and Assigns. Except as otherwise expressly provided in
this Article IX, the provisions of this Agreement shall inure to the benefit of,
and be binding upon, the successors, assigns, heirs, executors and
administrators of the Investor. The rights, remedies and entitlements of the
Investor under this Agreement may be assigned in full or in part at any time
after the date of this Agreement to an Affiliate (as defined below). Any
assignment to a non-Affiliate shall require prior written consent of the
Company. No such assignment, whether to an Affiliate or a non-Affiliate, shall
be effective unless the transferee, as a condition to such transfer, agrees in
writing that he or it will receive and hold such securities subject to the

                                      -23-
<PAGE>

provisions of this Agreement. In all cases of assignment, the Investor shall
give the Company written notice, stating the name and address of said transferee
and identifying the securities that are being assigned. For purposes of this
Article IX, an "Affiliate" shall mean any direct or indirect general or limited
partner or member, and a person that directly or indirectly, through one or more
intermediaries, controls, is controlled by, or is under common control with, the
Investor. The Company may not assign its rights hereunder.

         9.4. Entire Agreement; Amendment. This Agreement, the Registration
Rights Agreement and the other documents delivered pursuant hereto constitute
the full and entire understanding and agreement among the parties with regard to
the subjects hereof and thereof. Neither this Agreement nor any term hereof may
be amended, waived, discharged or terminated orally, but only by a written
instrument signed by the holders of at least a majority of the shares of
Purchase Shares then issued and outstanding and a representative of the Company
so authorized by its Board of Directors.

         9.5. Notices. All notices and other communications required or
permitted hereunder shall be given in writing and shall be deemed effectively
given upon personal delivery or three (3) business days following upon deposit
with the United States Postal Service, by certified mail, return receipt
requested, postage prepaid, or otherwise delivered by hand or by messenger,

or at such other address as the Company shall have furnished to the Investor.

         9.6. Delays or Omissions: Remedies Cumulative. No delay or omission to
exercise any right, power or remedy accruing to the Investor, upon any breach or
default under this Agreement, shall impair any such right, power or remedy of
the Investor or be construed to be a waiver of any such breach or default, or an
acquiescence therein, or of or in any similar breach or default thereafter
occurring; nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. All
of the Investor's remedies, either under this Agreement, or by law or otherwise
afforded to the Investor, shall be cumulative and not alternative.

         9.7. Agent's Fees. Except as set forth in Schedule 3.26, each party (i)
represents and warrants that it has retained no finder or broker in connection
with the transactions contemplated by this Agreement (except as disclosed to the
other parties hereto as of the date hereof) and (ii) hereby agrees to indemnify
and to hold the other parties harmless of and from any liability for commissions
or compensation in the nature of an agent's, finder's or broker's fee to any
broker or other person or firm (and the cost and expenses of defending against
such liability or asserted liability) for which said party is responsible.

         9.8. Expenses. Each party shall bear its own expenses and legal fees
(and expenses and disbursements of its legal counsel) incurred on its behalf
with respect to this Agreement and the transactions contemplated hereby.

         9.9. Construction of Certain Terms. The titles of the articles,
sections, and subsections of this Agreement are for convenience of reference
only and are not to be considered in construing this Agreement. Wherever the
words "including," "include" or "includes" are used in this Agreement, they
shall be deemed followed by the words "without limitation." References to any
gender shall be deemed to mean any gender.

         9.10. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

         9.11. Legends. Each of the Purchased Shares and the Note Shares will
bear the following legend:

               The securities represented by this certificate and the securities
               issuable upon conversion hereof have not been registered with the
               United States Securities and Exchange Commission under the
               Securities Act of 1933 (the "Securities Act"), or the securities
               commission of any state under any state securities law. The
               securities represented by this certificate may not be offered,
               sold or otherwise transferred unless (i) a registration statement
               under the Securities Act and any applicable state securities laws
               shall have become effective with regard thereto, or (ii) in the
               opinion of counsel

                                      -25-

               acceptable to the Company, registration under the Securities Act
               and applicable state securities laws is not required in
               connection with such proposed transfer.

         9.12. Timely Performance. Time is of the essence as to the performance
of the obligations required of the respective parties under this Agreement.

                                    ARTICLE X
                                   TERMINATION

         10.1. Termination.

               (a) This Agreement may be terminated at any time prior to the 2nd
Closing whether before or after the Special Meeting:

                    (i) by mutual written consent of the Company and the
          Investor, effective as of the date specified in the mutual consent; or

                    (ii) by either the Company or the Investor, effective as of
          the date of mailing or other transmission of notice, if a court of
          competent jurisdiction or other governmental entity has issued a
          nonappealable final order, decree or ruling or taken any other
          nonappealable final action, in each case having the effect of
          permanently restraining, enjoining or otherwise prohibiting the
          purchase by the Investor or the issuance by the Company of the
          Purchased Shares or Note Shares; or

                    (iii) by the Company or the Investor, effective as of the
          date of mailing or other transmission of notice, at any time prior to
          the 2nd Closing, if there has been a material breach of any
          representation, warranty, covenant or agreement, or a failure to
          satisfy any condition precedent to closing on the part of the other
          party set forth in the Agreement, which breach or failure would impair
          the ability of the breaching party to consummate the transactions
          contemplated by the Agreement and which, in the case of a failure of a
          condition precedent, is such that it cannot be cured prior to the date
          fixed for closing; provided, however, that such termination shall not
          limit limitation for such breach of the Agreement.

               (b) If not terminated prior to the 2nd Closing as provided in
this Article X, this Agreement shall terminate if the 2nd Closing does not occur
on or before December 31, 2000, or such later date to which the parties may
reasonably agree.

               (c) This Agreement shall terminate, with the exception of the
provisions of Article VIII herein, at such time after the 2nd Closing as the
Investor owns less than ten percent (10%) of the issued and outstanding Common
Stock of the Company.

                                      -27-

                          REGISTRATION RIGHTS AGREEMENT

         This REGISTRATION RIGHTS AGREEMENT (the "AGREEMENT") is entered into as
of August 30, 2000, by and between XATA CORPORATION, a Minnesota corporation
(the "COMPANY") and JOHN DEERE SPECIAL TECHNOLOGIES GROUP, INC., a Delaware
corporation (the "INVESTOR").

                                    RECITALS:

         A. Concurrently herewith, the Company has agreed to sell to the
Investor up to 3,147,000 shares (the "PURCHASED SHARES") of Common Stock of the
Company (the "COMMON STOCK") pursuant to that certain Stock Purchase Agreement
of even date herewith (the "STOCK PURCHASE AGREEMENT") between the Company and
the Investor

         B. Concurrently herewith, the Company has granted to the Investor an
option to convert that certain $1,000,000 Promissory Note from the Company to
the Investor (the "NOTE") into shares (the "NOTE SHARES") of Common Stock
pursuant to the Stock Purchase Agreement.

         C. Concurrently herewith, XATA Investment Partners, LLC has agreed to
sell to the Investor up to 200,000 shares (the "SELLING STOCKHOLDER SHARES") of
Common Stock pursuant to the Selling Stockholder Agreement.

         D. It is a condition to the consummation of the transactions
contemplated by the Stock Purchase Agreement that the Company and the Investor
enter into this Agreement whereby the Company shall grant, and the Investor
shall obtain, the rights relating to the registration of the Registrable
Securities under the Securities Act, as set forth in this Agreement.

         NOW, THEREFORE, in consideration of the mutual promises and covenants
hereinafter set forth, the parties agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

         1.1. Certain Definitions. For purposes of this Agreement:

              (a) The term "COMMISSION" means the Securities and Exchange
Commission.

              (b) The term "FORM S-3" means such form under the Securities Act
as is in effect on the date hereof or any successor form under the Securities
Act;

<PAGE>

              (c) The term "HOLDERS" means the Investor and any other person
holding Registrable Securities to whom these registration rights have been
transferred pursuant to Section 2.8 hereof.

              (d) The terms "REGISTER," "REGISTERED" and "REGISTRATION" refer to
a registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended, or
successor statute (the "SECURITIES ACT"), and the declaration or ordering of
effectiveness of such registration statement or document.

              (e) The term "REGISTRABLE SECURITIES" means (i) the Purchased
Shares and the Note Shares, (ii) the Selling Stockholder Shares and (iii) any
other shares of Common Stock issued as (or issuable upon the conversion or
exercise of any warrant, right or other security which is issued as) a dividend
or other distribution with respect to, or in exchange for or in replacement of,
the Registrable Securities; provided, however, that the foregoing definition
shall exclude in all cases any Registrable Securities sold by a person in a
transaction in which his or her rights under this Agreement are not assigned.
Notwithstanding the foregoing, shares of Common Stock or other securities will
only be treated as Registrable Securities if and so long as they have not been
(A) sold to or through a broker or dealer or underwriter in a public
distribution or a public securities transaction, or (B) sold in a transaction
exempt from the registration and prospectus delivery requirements of the
Securities Act under Section 4(1) thereof so that all transfer restrictions, and
restrictive legends with respect thereto, if any, are removed upon the
consummation of such sale and are not eligible for resale under Rule 144.

                                   ARTICLE II
                               REGISTRATION RIGHTS

         2.1. Demand Registration.

              (a) If the Company shall receive, any time and from time to time
on or after the date hereof, a written request from the Holders of 25% of the
Registrable Securities then outstanding that the Company file a registration
statement under the Securities Act, then the Company shall, within ten (10) days
of the receipt thereof, give written notice of such request to all Holders and
shall, subject to the limitations of subsection 2.1(b) and 2.1(d), use its best
efforts to effect as soon as practicable, the registration under the Securities
Act of all Registrable Securities which the Holders request in writing to be
registered within twenty (20) days of the mailing of such notice by the Company.

              (b) If the Holders initiating the registration request hereunder
("INITIATING HOLDERS") intend to distribute the Registrable Securities covered
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to this Section 2.1 and the Company
shall include such information in the written notice referred to in subsection
2.1(a). The underwriter will be selected by a majority in interest of the
Initiating Holders and reasonably approved by the Company. In such event, the
right of any Holder to include its Registrable Securities in such registration
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's Registrable Securities in

                                      -2-
<PAGE>

the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder) to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company as provided in subsection 2.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this
Section 2.1, if the underwriter advises the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the Initiating Holders shall so advise all Holders of
Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares of Registrable Securities that may be included in the
underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder. The Company shall
have the right to include securities for its own account in such registration,
if permitted by the registration form to be filed and the underwriter so agrees,
but only if such inclusion will not limit the number of securites offered by the
Holders.

              (c) Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting a registration statement pursuant to this Section 2.1, a
certificate signed by the President or Chief Executive Officer 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 and it is therefore essential to
defer the filing of such registration statement, the Company shall have the
right to defer such filing for a period of not more than ninety (90) days after
receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right more than once in any twelve (12) month
period.

              (d) In addition and without limitation of Section 2.11 hereof, the
Company shall not be obligated to effect, or to take any action to effect, any
registration pursuant to this Section 2.1:

                   (i) After the Company has effected two registrations pursuant
to Section 2.1 and such registrations have been declared or ordered effective;

                   (ii) During the ninety (90) day period prior to the Company's
good faith estimate of the date of filing of a registration subject to Section
2.2 hereof; provided that the Company (i) is using its best efforts to cause
such registration statement to become effective and (ii) provides written notice
of such proposed filing to the Holders within thirty (30) days after receipt of
the written request from the Holders pursuant to Section 2.1(a); or

                   (iii) If the Initiating Holders proposed to dispose of shares
of Registrable Securities that may be immediately registered on Form S-3 (or any
successor form that provides for short-form registration) pursuant to a request
made pursuant to Section 2.3 below; or

                   (iv) If the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an

                                      -3-
<PAGE>

aggregate price to the public (net of any underwriters' discounts or
commissions) of less than $100,000; or

                   (v) If the Company has, within the six (6) month period
preceding the date of such request, effected two (2) registrations on Form S-3
for the Holders pursuant to this Section 2.1 that have been declared or ordered
effective.

         2.2. Company Registration.

              (a) If the Company proposes to register (including for this
purpose a registration effected by the Company for shareholders other than the
Holders) any of its securities under the Securities Act in connection with the
public offering of such securities solely for cash (other than registration
relating solely to the sale of securities to participants in a Company stock
plan, an offering or sale of securities pursuant to a Form S-4 (or successor
form) registration statement or a registration in which the only stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being registered), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty (20) days after mailing of such notice by the
Company, the Company shall, subject to the provisions of Section 2.7, cause to
be registered under the Securities Act all of the Registrable Securities that
each such Holder has requested to be registered.

              (b) In connection with any offering involving an underwriting of
shares of the Company's capital stock, the Company shall not be required under
Section 2.2(a) to include any of the Holders' securities in such underwriting
unless they accept the terms of the underwriting as agreed upon between the
Company and the underwriters selected by it (or by other persons entitled to
select the underwriters), and then only in such quantity as the underwriters
determine in their sole discretion will not jeopardize the success of the
offering by the Company. If the total amount of securities, including
Registrable Securities, requested by shareholders to be included in such
offering exceeds the amount of securities sold other than by the Company that
the underwriters determine in their sole discretion is compatible with the
success of the offering, the underwriters may limit the amount of securities to
be included in the registration and underwriting by the selling shareholders.
The Company shall so advise all Holders of Registrable Securities which would
otherwise be registered and underwritten pursuant hereto, and the number of
securities that may be included in the registration and underwriting shall be
allocated first, among the initiating holders on a pro rata basis, or as the
Company and the initiating holders, if any, may determine and second, among the
Holders and other participating holders, other than initiating holders, if any,
requesting registration in proportion, as nearly as practicable, to the
respective amounts of securities, including Registrable Securities, that such
holders, including Holders, have requested pursuant to this Section 2.2 to
include in such registration. If any Holder disapproves of the terms of any such
underwriting, he may elect to withdraw therefrom by written notice to the
Company and the underwriters. Any Registrable Securities excluded or withdrawn
from such underwriting shall be withdrawn from such registration.

                                      -4-
<PAGE>

         2.3. Form S-3 Registration. In case the Company shall receive from the
Holders of Registrable Securities a written request or requests that the Company
effect a registration on Form S-3 and any related qualification or compliance
with respect to all or a part of the Registrable Securities owned by such
Holders, the Company will:

              (a) Promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders; and

              (b) As soon as practicable, effect such registration and all such
qualifications and compliances as may be requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any Holder of Holders
joining in such request as are specified in a written request given within
fifteen (15) days after receipt of such written notice from the Company;
provided, however; that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 2.3 if:

                   (i) Form S-3 is not available for such offering by the
Holders;

                   (ii) The Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public (net of any underwriters' discounts or commissions) of less
than $100,000; or

                   (iii) The Company has, within the twelve (12) month period
preceding the date of such request, effected two (2) registrations on Form S-3
for the Holders pursuant to this Section 2.3 that has been declared or ordered
effective.

              (c) Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders.

         2.4. Obligations of the Company. Whenever required under this Section 2
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

              (a) Prepare and file with the Commission a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of twenty-five percent (25%) of the Registrable Securities registered
thereunder, keep such registration statement effective for up to one hundred
eighty (180) days.

              (b) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to

                                      -5-
<PAGE>

the disposition of all securities covered by such registration statement for up
to one hundred eighty (180) days.

              (c) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

              (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or blue sky
laws of such jurisdictions as shall be reasonably requested by the Holders;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions.

              (e) In the event of an underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering, and each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

              (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing, such obligation to continue until the earlier of (i) the sale of all
Registrable Securities registered pursuant to a registration statement of which
such prospectus forms a part or (ii) the withdrawal of such registration
statement.

              (g) Cause all such Registrable Securities registered pursuant to
this Agreement to be listed on each securities exchange on which similar
securities issued by the Company are then listed.

              (h) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to this Agreement and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

              (i) Make available for inspection by any Holder of Registrable
Securities covered by such registration statement, any underwriter participating
in any disposition pursuant to such registration statement and any attorney,
accountant or other agent retained by any such seller or underwriter, all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors, employees and independent
accountants to supply all information reasonably requested by any such Holder,
underwriter, attorney, accountant or agent in connection with such registration
statement, in each case pursuant to confidentiality agreements, as appropriate.

                                      -6-
<PAGE>

              (j) Cause the Company's officers to make presentations to
potential purchasers of the Registrable Securities, as reasonably requested by
any Holder of Registrable Securities covered by such registration statement or
any underwriter participating in any disposition pursuant to such registration
statement.

              (k) Permit any Holder of Registrable Securities, which Holder, in
the sole judgment exercised in good faith of such Holder, might be deemed to be
a controlling person of the Company (within the meaning of the Securities Act or
the Exchange Act), to participate in the preparation of any registration
statement covering such Holder's Registrable Securities and to include therein
material, furnished to the Company in writing, which in the reasonable judgment
of such Holder should be included and which is reasonably acceptable to the
Company.

              (l) Use its best efforts to furnish, at the request of any Holder
requesting registration of Registrable Securities pursuant to this Section 2, on
the date that such Registrable Securities are delivered to the underwriters for
sale in connection with a registration pursuant to this Section 2, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities become effective, (i) an opinion, dated such
date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities and (ii) a letter
dated such date, from the independent certified public accountants of the
Company, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters, if any, and to the Holders requesting registration of
Registrable Securities.

              (m) Otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission and make available to its security
holders, in each case as soon as practicable, an earning statement covering a
period of at least twelve (12) months, beginning after the effective date of the
registration statement, which earning statement shall satisfy the provisions of
Section 11(a) of the Securities Act.

         2.5. Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 2 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

         2.6. Expenses of Registration.

              (a) Expenses of Demand Registration. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 2.1, including
(without limitation) all registration, filing and qualification fees, stock
transfer taxes, printers' and accounting fees, and fees and disbursements of
counsel for the Company, shall be borne by the Company; provided, however, that
the Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to

                                      -7-
<PAGE>

Section 2.1 if the registration request is subsequently withdrawn at the request
of the Holders of a majority of the Registrable Securities to be registered (in
which case all participating Holders shall bear such expenses), unless the
Holders of a majority of the Registrable Securities agree to forfeit their right
to one (1) demand registration pursuant to Section 2.1.

              (b) Expenses of Company Registration. All expenses other than
underwriting discounts and commissions reasonably incurred in connection with
registrations, filings or qualifications of Registrable Securities pursuant to
Section 2.2 for each Holder, including (without limitation) all registration,
filing, and qualification fees, printers' and accounting fees, and fees and
disbursements of counsel for the Company, shall be borne by the Company.

              (c) Expenses of Registration on Form S-3. All expenses other than
underwriting discounts and commissions incurred in connection with registrations
requested pursuant to Section 2.3, including (without limitation) all
registration, filing, qualification, printers' and accounting fees and the fees
and disbursements of one counsel for the selling Holders selected by them, shall
be borne by the Company.

         2.7. Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 2:

              (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any "underwriter" (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Securities Exchange Act of 1934,
as amended (the "EXCHANGE ACT"), against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "VIOLATION"):

                   (i) Any untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained in such registration statement or any amendments or supplements
thereto;

                   (ii) The omission to state therein a material fact required
to be stated therein, or necessary to make the statements therein not
misleading;

                   (iii) The omission to state in any preliminary prospectus or
final prospectus a material fact necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading; or

                   (iv) Any material violation by the Company of the Securities
Act, the Exchange Act, any state securities law or any rule or regulation
promulgated under the Securities Act, the Exchange Act or any state securities
law.

The Company will pay to each such Holder, underwriter or controlling person, as
actually incurred, any legal or other expenses reasonably incurred by them in
connection with

                                      -8-
<PAGE>

investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
2.7(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability, or action if such settlement is effected without the consent
of the Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable to any Holder, underwriter or controlling person for any such
loss, claim, damage, liability, or action to the extent that it arises out of or
is based upon a Violation which occurs; (A) in reliance upon and in conformity
with written information furnished for use in connection with such registration
by any such Holder, underwriter or controlling person; or (B) as a result of
failure of any holder to deliver a prospectus, at all or in a timely manner,
provided further, that in no event shall any indemnity under this subsection
2.7(a) exceed the net proceeds from the offering received by the Company.

              (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act or the Exchange
Act, any underwriter, any other Holder selling securities in such registration
statement and any controlling person of any such underwriter or other Holder,
against any losses, claims, damages, or liabilities (joint or several) to which
any of the foregoing persons may become subject, under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereto) arise out of or are
based upon any Violation, in each case to the extent that such Violation occurs
in reliance upon and in conformity with written information furnished by such
Holder for use in connection with such registration; and each such Holder will
pay, as actually incurred, any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this subsection 2.7(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 2.7(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder (which consent shall not be unreasonably
withheld); provided further, that in no event shall any indemnity under this
subsection 2.7(b) exceed the net proceeds from the offering received by such
Holder.

              (c) Promptly after receipt by an indemnified party under this
Section 2.7 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.7, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the reasonable fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any

                                      -9-
<PAGE>

liability to the indemnified party under this Section 2.7, but the omission so
to deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 2.7.

              (d) If the indemnification provided for in this Section 2.7 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the Violation(s) that resulted in such loss, liability, claim,
damage or expense as well as any other relevant equitable considerations;
provided, that in no event shall any contribution by a Holder or the Company
under this subsection 2.7(d) exceed the net proceeds from the offering received
by such Holder or the Company, respectively. The relative fault of the
indemnifying party and of the indemnified party shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties'
relative intent, knowledge, access to information, and opportunity to correct or
prevent such statement or omission.

              (e) The obligations of the Company and Holders under this Section
2.7 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 2, and otherwise. No indemnifying
party, in the defense of any such loss, claim, change, liability or action,
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 a provision
thereof, the giving by the claimant or plaintiff to such indemnified party of a
release from all liability in respect to such loss, claim, damage, liability or
action.

         2.8. Assignment of Registration Rights. The rights to cause the Company
to register Registrable Securities pursuant to this Section 2 may be assigned
(but only with all related obligations) by a Holder to (i) any "affiliate" of
such Holder (as defined under the Securities Act), (ii) such Holder's spouse,
parents, siblings, children or grandchildren, or other members of such Holder's
immediate or extended family (including relatives by marriage), or to a
custodian, trustee or other fiduciary for the account of such Holder or members
of such Holder's immediate or extended family in connection with an estate
planning transaction, or (iii) a transferee or assignee of at least 100,000
shares of such securities (as adjusted for stock dividends, combinations,
recapitalizations, splits and otherwise), provided the Company is, within a
reasonable time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned and such transferee or
assignee agrees to become a party to this Agreement. For the purposes of
determining the number of shares of Registrable Securities held by a transferee
or assignee, the holdings of transferees and assignees of a business entity who
are affiliates, retired affiliates of such entity (including spouses and
ancestors, lineal descendants and siblings of such affiliates or affiliates who
acquire Registrable Securities by gift, will or intestate succession) shall be
aggregated together and with the business entity; provided that all assignees
and transferees who would not qualify individually for assignment of
registration rights shall have a

                                      -10-
<PAGE>

single attorney-in-fact for the purpose of exercising any rights, receiving
notices or taking any action under Section 2.

         2.9 Limitations on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of a majority of the Registrable Securities then outstanding,
enter into any agreement with any holder or prospective holder of any securities
of the Company which would allow such holder or prospective holder (a) to
include such securities in any registration filed under Section 2.1 or 2.3
hereof, unless under the terms of such agreement, such holder or prospective
holder may include such securities in any such registration only to the extent
that the inclusion of its securities will not reduce the amount of the
Registrable Securities of the Holders which is included, or (b) to make a demand
registration which could result in such registration statement being declared
effective within one hundred eight (180) days of the effective date of any
registration effected pursuant to Section 2.1 or 2.3 hereof.

         2.10. Reports under Securities Exchange Act of 1934. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the Commission that may at
any time permit a holder to sell securities of the Company to the public
pursuant to a registration on Form S-3 or without registration, the Company
agrees to:

              (a) Make and keep public information available, as those terms are
understood and defined in Commission Rule 144, at all times after the effective
date of the first registration statement filed by the Company for the offering
of its securities to the general public so long as the Company remains subject
to the periodic reporting requirements under Sections 13 or 15(d) of the
Exchange Act;

              (b) File with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

              (c) Furnish to any Holder, so long as accurate and so long as the
Holder owns any Registrable Securities, forthwith upon request (i) a written
statement by the Company that it has complied with the reporting requirements of
Commission Rule 144 (at any time after ninety (90) days after the effective date
of the first registration statement filed by the Company), the Securities Act
and the Exchange Act (at any time after it has become subject to such reporting
requirements), or that it qualifies as a registrant whose securities may be
resold pursuant to Form S-3 (or any successor form that provides for short-form
registration), (ii) a copy of the most recent annual or quarterly report of the
Company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the Commission which permits the selling of any such
securities without registration or pursuant to such form.

         2.11 Termination of Registration Rights. The right of any Holder to
request registration or inclusion in any registration pursuant to Section 2.1,
2.2 or 2.3 hereof shall terminate at such time as such Holder owns less than
five percent (5%) of the outstanding capital stock of the

                                      -11-
<PAGE>

Company and such Holder can sell all of such Holder's Registrable Securities
under Rule 144 during any ninety (90) day period.

         2.12. Consolidations; Mergers. The Company shall not, directly or
indirectly, enter into any merger, consolidation or reorganization in which the
Company is not the surviving corporation unless the proposed surviving
corporation shall, prior to such merger, consolidation or reorganization, agree
in writing to assume the obligations of the Company under this Agreement, and
for that purpose references hereunder to "Registrable Securities" shall be
deemed to be references to the securities that the Investor or the Holders of
Registrable Securities would be entitled to receive in exchange for Registrable
Securities under any such merger, consolidation or reorganization.
