                                 COMPANY SUMMARY

         Datakey, Inc. was incorporated under the laws of the State of Minnesota
in 1976 under the name "The Systems Group, Inc." In 1980, the Company changed
its name to Datakey, Inc. The Company provides product, subsystem and system
solutions to record, store and transmit electronic information. Datakey also
manufactures and sells products and systems directed to the information security
market which enable user identification and authentication, secure data exchange
and information validation. It also provides OEM products, consisting of
proprietary memory keys, cards and other custom-shaped tokens that serve as a
convenient way to carry electronic information and are packaged to survive in
portable environments.

         The Company's first portable memory products, consisting of an
electronic key and support electronics, were introduced in 1981 for applications
requiring convenient storage, transportation and management of information. The
Company's current products utilize semiconductor technology to provide a storage
device more versatile than conventional portable information products such as
keys, badges and magnetic stripe cards. The Company's current product line of
portable memory devices and associated interface products provide up to
32,768,000 bits of data storage which are used in a wide range of applications
including communications security, computer security, facility security, vending
and process control.

         Each of the Company's portable memory systems consist of one or more
portable memory devices, access devices and, for certain models, interface
modules containing microprocessors. These components, together with the user's
processor-based equipment, function as an integrated system allowing
instantaneous processing of personalized data carried within a portable data
carrier. Through the incorporation of advanced semiconductor memory technology,
the Company's portable memory device is able to store and carry substantial
amounts of information. When the memory device is used in conjunction and with
the other components of the Company's system, information can be selectively
altered, added to or erased, as required, to effectively and reliably manage or
control a particular activity or transaction.

         In 1997, the Company introduced end-user systems that utilize smart
cards or smart keys and are designed to provide advanced information security
utilizing digital signatures and encryption. These systems incorporate hardware
and software to provide a higher level of security than is obtainable with
current software only solutions.

         The Company's principal executive offices are located at 407 West
Travelers Trail, Burnsville, Minnesota 55337, and its telephone number is (612)
890-6850.

                                  RISK FACTORS

         An investment in the Securities offered hereby involves a high degree
of risk. The Securities offered hereby should not be purchased by persons who
cannot afford the entire loss of their investment. Prospective investors should
carefully consider the following factors, in addition to the other information
presented in this Prospectus, in evaluating the Company and its businesses. This
Prospectus contains certain forward-looking statements. The Company's actual
results could differ materially from the results currently anticipated by
management of the Company in such forward-looking statements as a result of a
variety of factors, including, but not limited to, "Risk Factors" described
below, and elsewhere, in this Prospectus.

   1. Losses: The Company incurred losses of $2,289,000 and $2,909,000 in 1998
and 1999, respectively, related primarily to the development of its information
security products. The Company expects material additional losses to continue
through 2000. The Company's ability to achieve profitability depends on
significantly increasing sales of its information security products, and based
on financial results to date, there is no assurance the Company will be
successful in this regard.

   2. Reliance on information security products: The Company's future growth and
profitability directly depends on the success of its information security
(Information Security Solutions or ISS) products, which is subject to all of the
risks inherent in the establishment of any new business venture. The Company's
development, manufacture and distribution of its information security products
is consuming the majority of the Company's cash and is unprofitable. Sales
levels of such products lie far below the Company's projections set at the
beginning of 1999, and there is no assurance that sales of ISS products will
ever be sufficient for the Company to attain profitability. If, for any reason,
the Company is unsuccessful in significantly increasing the sales of its
information security products and attaining overall profitability, the Company's
ability to continue operations in its current form would be doubtful.

   3. Dependence on customer acceptance: While Datakey performs market research
and beta testing to determine the viability of its new products, actual user
acceptance will ultimately dictate the success of the marketing and sales
efforts of new products such as SignaSURE CIP and ESS. Based on the Company's
experience to date, no assurances exist that Datakey's products will ultimately
receive satisfactory customer acceptance or that investments already made and
additional investments planned for 2000 will result in an acceptable financial
return.

   4. Need for additional capital: Even though the Company raised $5,500,000
pursuant to its October 1999 and February 2000 private offerings and an
additional $1,065,565 from the exercise of outstanding warrants since January 1,
2000, the Company may require additional capital later in 2000, the amount of
which will depend primarily on the sales levels of the Company's information
security products. To date, the Company has not been able to accurately project
future information security product sales, and there is no assurance that its
current sales projections will be met. If the Company is not successful in
significantly increasing the sales levels of its integrated system solutions
products in 2000, the Company may be forced at some point in 2000 or thereafter
to curtail or discontinue operations unless it was then in a position to obtain
the required additional capital. Such capital may not be available on terms
satisfactory to the Company, or at all.

   5. Volatility of Stock Price: The market price of the Company's Common Stock
has appreciated substantially since November 1, 1999, rising from $1.00 per
share to $16.813 per share on March 14, 2000. The Company is not aware of any

<PAGE>

particular event or circumstance which might account for this increase, although
it is aware that technology companies are currently deemed to be attractive
investments. However, any unfavorable disclosure relating to the Company's
development or marketing of its ISS product line, product effectiveness,
competition, as well as other matters would likely materially adversely impact
the market price of the Company's Common Stock.

   6. Risk of rapid technological change: In the information security market,
Datakey faces significant risks due to the rapid and continual changes in
available technology. Datakey's information security end-user products such as
SignaSURE CIP and SignaSURE ESS integrate hardware tokens with software that
provides a much higher level of security than software implementations alone.
Software only solutions may be developed in the future which could provide this
security. Such development could materially adversely affect Datakey's business.

   7. Price competition: While Datakey believes that its strategy of providing
token-based product solutions at a price that is competitive with software-only
products is attainable, there are no assurances that competitive pressures will
not force the Company to accept reduced margins to compete in the future. Large
companies with significantly greater resources have recognized the need for
information security and will likely enter this market as competitors with much
greater financial resources. A portion of the end-user's product cost consists
of royalties and license fees, which would need to be re-negotiated in order to
maintain acceptable profit margins.

   8. Dependence on Management and Technical Personnel: The Company's ability to
meet its projections for the Company's information security business depends
upon the efforts and abilities of its management team, its software engineers
and other technical personnel. The Company's inability to retain such highly
skilled persons due either to its current economic circumstances or the intense
competition faced in the market for such persons would substantially limit the
Company's ability to further its efforts in this new business venture.

   9. Delays in product delivery schedules: Datakey's success depends to a
certain extent on its ability to meet its currently scheduled development
timetable. Delays in the release of new products, as well as enhancements to
current products, will cause operational inefficiencies, increased development
costs and reduced revenues and may affect customer acceptance.

   10. Risk of integrated information security products: Although the Company's
new products are designed to operate seamlessly with popular application
programs, new application programs that integrate information security into
their product could erode the future market for these Datakey products.

   11. Dependence on new marketing and sales organization: The future revenue of
Datakey end-user systems is dependent on the success of a new and untested
marketing and direct sales organization.

   12. Competition from other information transmission media: Corporate
utilization of the Internet and internal intranets dictate a need for
information security, but there are no assurances that other, more secure
information transmission media may not become available in the future that would
preclude the need for the type of information security the Company's products
offer.

                                 USE OF PROCEEDS

         The Company is not selling any of the Shares and will not receive any
proceeds from the sale of the Shares by the Selling Shareholders.

(1)      Includes an aggregate of (i) 488,275 shares that may be purchased by
         certain Selling Shareholders upon exercise of warrants issued in May
         1998 and October 1999, which shares are not being offered hereby, and
         (ii) 880,000 shares that may be purchased by the Selling Shareholders
         upon exercise of warrants issued in February 2000, which shares are
         being offered hereby.


<PAGE>

(2)      The above numbers assume that the Selling Shareholders will exercise
         the Warrants for cash. If the Selling Shareholders use the cashless
         exercise alternative, the actual number of shares of Common Stock
         issued will be fewer, depending on the market value of the underlying
         shares of Common Stock immediately prior to exercise.

(3)      The percentage of shares beneficially owned by each Selling Shareholder
         is based on 8,887,879 shares of Common Stock outstanding, including
         8,007,879 shares outstanding as of March 16, 2000 and 880,000 shares
         to be outstanding if all February 2000 warrants are exercised. Assumes
         the sale of all the Shares being offered hereby.

(4)      The shares shown for each of Betty Johnson, David B. Johnson and the
         David B. Johnson Family Foundation, respectively, each of whom is a
         Selling Shareholder, are not included in the holdings of the others
         even though each may be deemed to beneficially own all of the shares.
         Betty Johnson and David Johnson are married.

(5)      Includes 10,000 shares owned by Mr. Lipkin's daughter for which he has
         dispositive power and shares voting power.

(6)      Includes 6,300 shares and a warrant to purchase 6,529 shares held
         jointly by Daniel Perkins and Patrice Perkins, husband and wife. Shares
         held in individual trusts are included in the respective holdings.

(7)      Does not include the shares held by Miller, Johnson & Kuehn,
         Incorporated ("MJK"), a Selling Shareholder. David Johnson, Paul Kuehn,
         Stanley Rahm and Eldon Miller are principals of MJK and may be deemed
         to beneficially own such shares.


         The Selling Shareholders and the officers and directors of any of such
Selling Shareholders have not held any positions or office or had any other
material relationship with the Company or any of its affiliates within the past
three years.

         The Company has agreed with the Selling Shareholders to file with the
Commission, under the Securities Act, a Registration Statement of which this
Prospectus forms a part, with respect to the resale of the Shares, and has
agreed to prepare and file such amendments and supplements to the Registration
Statement as may be necessary to keep the Registration Statement effective until
the earlier of (i) one year from the effectiveness of the Registration
Statement, or (ii) the date on which all of the Shares have been sold.

                              PLAN OF DISTRIBUTION

         All or a portion of the Shares offered by the Selling Shareholders
hereby may be sold from time to time by the Selling Shareholders or by pledgees,
donees, transferees or other successors in interest. Such sales may be made in
the over-the-counter market or otherwise at prices and at terms then prevailing
or at prices related to the then current market price, or in negotiated
transactions. The Shares may be sold by one or more of the following means: (a)
ordinary brokerage or market making transactions and transactions in which the
broker or dealer solicits purchasers; (b) block trades in which the broker or
dealer so engaged will attempt to sell the Shares as agent but may position and
resell a portion of the block as principal to facilitate the transaction; and
(c) purchases by a broker or dealer as principal and resales by such broker or
dealer for its account pursuant to this Prospectus. In effecting sales, brokers
or dealers engaged by the Selling Shareholders may arrange for other brokers or
dealers to participate. Brokers or dealers will receive commissions or discounts
from the Selling Shareholders in amounts to be negotiated immediately prior to
the sale. Such brokers or dealers and any other participating brokers or dealers
may be deemed to be "underwriters" within the meaning of the Securities Act in
connection with such sales. In addition, any securities covered by this
Prospectus which qualify for sale pursuant to Rule 144 under the Act may be sold
under Rule 144 rather than pursuant to this Prospectus.

         The Company and the Selling Shareholders have agreed to indemnify each
other against certain liabilities, including liabilities arising under the
Securities Act.

                            DESCRIPTION OF SECURITIES

         The aggregate number of shares of stock which the Company has the
authority to issue is 12,500,000 shares, consisting of 11,000,000 shares of
Common Stock, par value $.05, 400,000 shares of Convertible Preferred Stock,
150,000 shares of Series A Convertible Cumulative Preferred Stock and 950,000
shares of undesignated shares. Holders of Common Stock have no cumulative voting
rights and no preemptive rights. Upon liquidation or dissolution, the holders of
Common Stock will be entitled to share ratably in all assets available for
distribution after the payment or provision for payment of all debts and
liabilities and subject to the rights of the holders of any preferred stock
which may be outstanding. Each share of Common Stock is entitled to dividends as
may from time to time be declared by the Board of Directors out of funds legally
available therefor. The shares of Common Stock are quoted on the Nasdaq SmallCap
Market under the symbol "DKEY." The outstanding shares of Common Stock are, and
the shares of Common Stock offered hereby will be, fully paid and nonassessable.

                                  LEGAL MATTERS

         Certain legal matters associated with the Shares being offered hereby
will be passed upon for the Company by Fredrikson & Byron, P.A., Minneapolis,
Minnesota.

Item 15.  Indemnification of Directors and Officers.

         Section 302A.521 of the Minnesota Business Corporation Act provides
that a corporation shall indemnify any person who was or is threatened to be
made a party to any proceeding by reason of the former or present official
capacity of such person, against judgments, penalties and fines, including,
without limitation, excise taxes assessed against such person with respect to an
employee benefit plan, settlements and reasonable expenses, including attorneys'
fees and disbursements, incurred by such person in connection with the
proceeding, if, with respect to the acts or omissions of such person complained
of in the proceeding, such person has not been indemnified by another
organization or employee benefit plan for the same expenses with respect to the
same acts or omissions, acted in good faith, received no improper personal
benefit and Section 302A.255 (which pertains to director conflicts of interest),
if applicable, has been satisfied; in the case of a criminal proceeding, had no
reasonable cause to believe the conduct was unlawful; and in the case of acts or
omissions by person in their official capacity for the corporation, reasonably
believed that the conduct was in the best interests of the corporation, or in
the case of acts or omissions by persons in their capacity for other
organizations, reasonably believed that the conduct was not opposed to the best
interests of the corporation.

         Section 302A.521 also permits Minnesota corporations to amend their
Articles of Incorporation to limit or eliminate personal liability of directors
to the corporation or its shareholders for monetary damages for breach of
fiduciary duty; however, forbids any limitation or elimination of director
liability for (i) a breach of the director's duty of loyalty, (ii) acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law, (iii) corporate distributions which are either illegal or in
contravention of restrictions in the Articles, Bylaws or any agreement to which
the corporation is a party, (iv) violations of Minnesota securities laws, (v)
any transaction from which the director derived an improper personal benefit, or
(vi) any act or omission occurring prior to the effective date of the provision
in the corporation's Articles eliminating or limiting liability.

         Article 6.1 of the Registrant's Restated Articles of Incorporation, as
amended, reads as follows:


<PAGE>

         To the fullest extent permitted by the Minnesota Business Corporation
         Act as the same exists or may hereafter be amended, a director of this
         corporation shall not be personally liable to the corporation or its
         shareholders for monetary damages for breach of fiduciary duty as a
         director.

         The Company's Amended Bylaws provide for the indemnification of its
directors, officers, employees and agents in accordance with, and to the fullest
extent permitted by, Section 302A.521 of the Minnesota Business Corporation Act,
as amended from time to time.

         Insofar as the indemnification of liabilities arising under the 1933
Act, as amended, may be permitted to directors, officers and controlling persons
of the Company pursuant to the provisions of its Restated Articles of
Incorporation, Restated Bylaws and the provisions of the Minnesota Business
Corporation Act, or otherwise, the Company has been advised by counsel that in
the opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Act, as amended, and is, therefore,
unenforceable.

Item 16.  Exhibits.

         See Exhibit Index on page following signatures.

Item 17.  Undertakings.

(a)      The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which it offers or sells securities,
a post-effective amendment to this registration statement to:

                  (i) Include any prospectus required by section 10(a)(3) of the
                  Securities Act;

                  (ii) Reflect in the prospectus any facts or events arising
                  after the effective date of the Registration Statement (or the
                  most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represents a fundamental
                  change in the information set forth in the registration
                  statement; and

                  (iii) Include any additional material information with respect
                  to the plan of distribution not previously disclosed in the
                  Registration Statement or any material change to such
                  information in the Registration Statement.

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports file by the Registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement.

         (2) That for determining liability under the Securities Act of 1933,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.


<PAGE>

         (3) To remove from registration by means of a post-effective amendment
any of the securities that remain unsold at the termination of the offering.

(b) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

(c) The undersigned Registrant further undertakes that:

         (1) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

         (2) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

(d) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

RE:      Registration Statement on Form S-3 - Exhibit 5.1

Gentlemen/Ladies:

         We have acted as counsel for Datakey, Inc. (the "Company") in
connection with the Company's filing of a Registration Statement on Form S-3
(the "Registration Statement") relating to the registration under the Securities
Act of 1933 (the "Act") of an offering of 1,680,000 shares of Common Stock of
the Company by persons who are currently holders of Common Stock of the Company
(the "Shares") or who may become such holders upon exercise of outstanding
warrants (the "Warrants").

         In connection with rendering this opinion, we have reviewed the
following:

         1.       The Company's Restated Articles of Incorporation, as amended;

         2.       The Company's Bylaws, as amended;

         3.       Certain corporate resolutions, including resolutions of the
                  Company's Board of Directors pertaining to the issuance by the
                  Company of the Shares and the Warrants;

         4.       The Warrants; and.

         5.       The Registration Statement.

         Based upon the foregoing and upon representations and information
provided by the Company, we hereby advise you that in our opinion:

         1.       The Company's Restated Articles of Incorporation validly
                  authorize the issuance of the Shares registered pursuant to
                  the Registration Statement.

         2.       The Shares to be sold by the selling shareholders named in the
                  Registration Statement are or, upon exercise in accordance
                  with the terms and conditions of the Warrants, will be validly
                  issued and outstanding, fully paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" included in the Registration Statement and the related Prospectus.

Very truly yours,

FREDRIKSON & BYRON, P.A.


By /s/ Robert K. Ranum
Robert K. Ranum, Vice President






                            STOCK PURCHASE AGREEMENT


         This Agreement is made and entered into as of the 11th day of February,
2000, between Datakey, Inc., a Minnesota corporation (the "Company") and each of
the persons listed on Schedule 1 to this Agreement (the "Investors"). Reference
to any exhibits herein refers to the exhibits included in the Company's offering
materials dated February 3, 2000 (the "Offering Materials").

         For good and valuable consideration, the receipt and adequacy of which
are hereby acknowledged by the Company and each of the Investors, the Company
and the Investors agree as follows:

         1. Sale and Purchase of Securities. Subject to the terms and conditions
hereof, the Company agrees to sell to each Investor at the Closing (as defined
herein), and each Investor severally agrees to purchase from the Company at the
Closing, that number of shares of the Company's Common Stock (the "Shares") set
forth opposite each Investor's name on Schedule 1 at a purchase price of five
dollars ($5.00) per share, together with a five-year warrant in the form
attached hereto as Exhibit A (the "Warrant") to purchase that number of Shares
of the Company's Common Stock set forth on Schedule 1 at an exercise price of
five dollars ($5.00) per share. The Shares and the Warrants are referred to
herein collectively as the "Securities."

         2. Closing. The closing shall take place at the offices of Fredrikson &
Byron, P.A., Minneapolis, Minnesota 55402, at 1:00 p.m., Minneapolis time, on
Friday, February 11th, 2000 (the "Closing") and/or at such other place or time
as may be mutually acceptable to the Investors and the Company. At the Closing,
subject to the satisfaction of the conditions in Section 6 below, the Company
will deliver to each Investor a certificate representing the Shares purchased by
such Investor, together with a Warrant representing the right to purchase that
number of shares of Common Stock of the Company set forth opposite each
Investor's name on Schedule 1, against payment of the purchase price therefor by
certified check or wire transfer to the Company in the amounts set forth after
their respective names in Schedule 1 hereto.

         3. Representations and Warranties by the Company. To induce each
Investor to enter into this Agreement and to purchase the number of Securities
set forth after his or its name on Schedule 1, the Company hereby represents and
warrants to each Investor that:

                  3.1 Organization, Standing, Etc. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Minnesota, and has the requisite corporate power and authority to own
its properties and to carry on its business in all material respects as it is
now being conducted. The Company is duly qualified to do business as a foreign
corporation and is in good standing in all states or jurisdictions in which the
ownership or lease of its property or the conduct of its business requires such
qualification and the failure to be so qualified would have a materially adverse
effect on the Company's business.


<PAGE>

                  3.2 Authorization and Enforceability. The Company has full
legal power, right and authority to enter into this Agreement and the
Registration Rights Agreement among the Company and the Investors, the form of
which is attached hereto as Exhibit B (the "Registration Rights Agreement") and
to issue the Securities. This Agreement, the Registration Rights Agreement and
the Securities, have been duly authorized, executed and delivered on behalf of
the Company and are the valid and binding obligations of the Company,
enforceable in accordance with their respective terms and subject, as to
enforcement, to applicable bankruptcy, insolvency, reorganization, moratorium
and other laws affecting the rights of creditors generally, to the exercise of
judicial discretion as to the availability of equitable remedies such as
specific performance in injunction and subject, as to enforcement of the
indemnification provisions, to limitations under applicable securities laws. The
Securities when delivered pursuant to the terms of this Agreement will be
validly issued, fully paid and nonassessable.

                  3.3 Subsidiaries. The Company has one wholly owned subsidiary,

                          REGISTRATION RIGHTS AGREEMENT


         This Registration Rights Agreement is made and entered into as of the
11th day of February 2000, by and among Datakey, Inc., a Minnesota corporation
(the "Company") and the Investors listed on Schedule A attached hereto
(individually, an "Investor" and collectively, the Investors").

                                    RECITALS

         A. The Investors and the Company have entered into that certain Stock
Purchase Agreement, dated February 11, 2000 (the "Purchase Agreement").

         B. It is a condition to the transactions contemplated in the Purchase
Agreement that the Company provide the registration and other rights provided
herein and the parties hereto desire to provide for such rights on the terms and
conditions contained herein.

         NOW, THEREFORE, in consideration of the premises and covenants
contained herein, the parties hereto agree as follows:

         1. Defined Terms. Unless otherwise noted, all capitalized terms used
herein shall have the meanings afforded them in the Purchase Agreement and the
Exhibits attached thereto.

         2. Required Registration. Within 45 days of the Closing date (the "File
Date"), the Company shall file a Registration Statement under the Securities Act
of 1933, as amended (the "Securities Act"), in accordance with the provisions of
either Form S-1 or Form S-3, as required by the Securities and Exchange
Commission (the "Commission") covering (i) the resale of the Shares and (ii) the
issuance and resale of the Warrant Shares, and will use its best efforts to have
such Registration Statement become effective with the Commission as soon as
possible thereafter, and in any event, within 90 days of the date on which it is
filed. The Shares and the Warrants Shares are referred to herein as the
"Registrable Stock."

         3. Registration - General Provisions. In connection with the
registration of the Registrable Stock under the Securities Act, the Company
will:

                  (a) prepare and file with the Commission a registration
statement with respect to the Registrable Stock, within 45 days of the Closing
date of the Purchase Agreement, and use its best efforts to cause such
registration statement to become effective within 90 days of the date it is
filed and keep the prospectus which is a part of such Registration Statement
current until the earlier of the date on which: (i) all Registrable Stock has
been sold, or (ii) one year after the date it is declared effective by the
Commission;

                  (b) prepare and file with the Commission such amendments to
such Registration Statement and supplements to the prospectus contained therein
as may be necessary to keep such Registration Statement effective for the period
required by Section 3(a) above;


<PAGE>

                  (c) provide the Investors' counsel with reasonable
opportunities to review and comment on, and otherwise participate in, the
preparation of such Registration Statement;

                  (d) furnish to the Investors participating in such
registration and to the underwriters of the securities being registered, if any,
such reasonable number of copies of the Registration Statement, preliminary
prospectus, final prospectus and such other documents as the Investors and
underwriters may reasonably request in order to facilitate the public offering
of such securities;

                  (e) use its diligent, good faith efforts to register or
qualify the securities covered by such Registration Statement under such state
securities or blue sky laws of such jurisdictions as the Investors may
reasonably request, except that the Company shall not for any purpose be
required to execute a general consent to service of process (which shall not
include a "Uniform Consent to Service of Process" or other similar consent to
service of process which relates only to actions or proceedings arising out of
or in connection with the sale of securities, or out of a violation of the laws
of the jurisdiction requesting such consent) or to qualify to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified;

                  (f) notify the Investors, promptly after it shall receive
notice thereof, of the time when such Registration Statement has become
effective or a supplement to any prospectus forming a part of such Registration
Statement has been filed with the Commission;

                  (g) notify the Investors promptly of any request by the
Commission for the amending or supplementing of such Registration Statement or
prospectus or for additional information;

                  (h) prepare and file with the Commission, promptly upon the
request of the Investors, any amendments or supplements to such Registration
Statement or prospectus which, in the opinion of counsel for the Investors (and
concurred in by counsel for the Company), is required under the Securities Act
or the rules and regulations promulgated thereunder in connection with the
distribution of the shares of the Company's common stock by the Investors;

                  (i) prepare and promptly file with the Commission and promptly
notify the Investors of the filing of such amendment or supplement to such
Registration Statement or prospectus as may be necessary to correct any
statements or omissions if, at the time when a prospectus relating to such
securities is required to be delivered under the Securities Act, any event shall
have occurred as the result of which any such prospectus or any other prospectus
as then in effect would include an untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein, in the
light of the circumstances in which they were made, not misleading;

                  (j) advise the Investors, and the Investors' counsel, if any,
promptly after it shall receive notice or obtain knowledge thereof, of the
issuance of any stop order by the Commission suspending the effectiveness of

<PAGE>

such Registration Statement or the initiation or threatening of any proceeding
for that purpose and promptly use its best efforts to prevent the issuance of
any stop order or to obtain its withdrawal if such stop order should be issued;

                  (k) not file any amendment or supplement to such Registration
Statement or prospectus to which the Investors shall have reasonably objected on
the grounds that such amendment or supplement does not comply in all material
respects with the requirements of the Securities Act or the rules and
regulations promulgated thereunder, after having been furnished with a copy
thereof at least five business days prior to the filing thereof, unless in the
opinion of counsel for the Company the filing of such amendment or supplement is
reasonably necessary to protect the Company from any material liabilities under
any applicable federal or state law and such filing will not violate applicable
law; and

                  (l) at the request of the Investors, furnish on the effective
date of the Registration Statement and, if such registration includes an
underwritten public offering, at the closing provided for in the underwriting
agreement: (i) opinions, dated such respective dates, of the counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the Investors making such request, covering such
matters as such underwriters or Investors may reasonably request, and (ii)
letters, dated such respective dates, from the independent certified public
accountants of the Company, addressed to the underwriters, if any, and to the
Investors, covering such matters as such underwriters or Investors may
reasonably request, in which letter such accountants shall state (without
limiting the generality of the foregoing) that they are independent certified
public accountants within the meaning of the Securities Act and that in the
opinion of such accountants the financial statements and other financial data of
the Company included in the Registration Statement or the prospectus or any
amendment or supplement thereto comply in all material respects with the
applicable accounting requirements of the Securities Act.

         4. Registration Expense. The Company shall pay all Registration
Expenses (as defined below) in connection with the inclusion of shares of the
Company's common stock in any Registration Statement, or application to register
or qualify such shares under state securities laws, filed by the Company
hereunder, other than as set forth herein. For purposes of this Agreement, the
term "Registration Expenses" means the filing fees payable to the Commission,
any state agency and the NASD; the fees and expenses of the Company's legal
counsel and independent certified public accountants in connection with the
preparation and filing of the Registration Statement (and all amendments and
supplements thereto) with the Commission; and all expenses relating to the
printing of the Registration Statement, prospectuses and various agreements
executed in connection with the Registration Statement. Notwithstanding the
foregoing, the Investors will pay the fees and expenses of any legal counsel the
Investors may engage, as well as the Investors' proportionate share of any
custodian fees or commission or discounts which may be payable to any
underwriter.

         5. Penalty Payments. In the event that the Registration Statement
relating to the resale of the Registrable Stock is not (i) filed with the
Commission by the Company on or before the File Date, or (ii) declared effective
by the Commission within 120 days of the Closing date, then, the Company shall
pay the Investors the following amounts ("Penalty Payments"): (i) 1% of the
purchase price of the Stock (the "Purchase Price") paid by the Investors to the

<PAGE>

Company if (A) the Registration Statement is not filed with the Commission by
the File Date, and/or (B) the Registration Statement is not declared effective
by the Commission within 120 days of the Closing date, (ii) an additional 1% of
the Purchase Price if the Registration Statement is not declared effective by
the Commission within 150 days of the Closing date, and (iii) an additional 3%
of the Purchase Price for each 30-day period thereafter in which the
Registration Statement is not declared effective by the Commission. Penalties
for failure to file and/or to obtain effectiveness shall be cumulative. The
Company shall be liable to the Investor for a full 30-day period, determined in
accordance with the above schedule, regardless of by how many days it misses one
of the targeted filing or effective dates set forth above. All such Penalty
Payments shall be immediately payable by the Company to the Investors (on a pro
rata basis based on the number of shares of Stock purchased by each under the
Purchase Agreement) via wire transfer of immediately available funds by the
close of business on last day of each respective period set forth above.

         6. Indemnification. With respect to the registration of the resale of
the shares of Registrable Stock:

         (a) to the fullest extent permitted by law, the Company will indemnify
and hold harmless each Investor, the trustees, partners, officers, directors and
agents of each Investor, any underwriter (as defined in the Securities Act) for
such Investor and each person, if any, who controls such Investor 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") by the Company: (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
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 in connection with the offering
covered by the Registration Statement; and the Company will reimburse each such
Investor, trustee, partner, officer, director, agent, underwriter or controlling
person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the indemnity agreement contained in this
Section 6 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 in any such case 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 in reliance upon and in conformity with written information furnished to
it expressly for use in connection with such registration by an Investor,
trustee, partner, officer, director, agent, underwriter or controlling person of
an Investor.


<PAGE>

                  (b) to the extent permitted by law, each Investor will
indemnify and hold harmless the Company, each of its directors, each of its
officers, each person, if any, who controls the Company within the meaning of
the Securities Act, any underwriter and any other Investor selling securities
under the Registration Statement or any of such other Investor's, trustees,
partners, directors or officers or any person who controls such Investor,
against any losses, claims, damages or liabilities (joint or several) to which
the Company or any such director, officer, controlling person, underwriter or
other such Investor, or trustee, partner, director, officer or controlling
person of such other Investor 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 (and only to the extent) that
such Violation occurs in reliance upon and in conformity with written
information furnished by such Investor and stated to be specifically for use in
connection with such registration; and each such Investor will reimburse any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, underwriter or other Investor, or trustee, partner,
officer, director or controlling person of such other Investor in connection
with investigating or defending any such loss, claim, damage, liability or
action if it is judicially determined that there was such a Violation; provided,
however, that the indemnity agreement contained in this Section 6 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 Investor,
which consent shall not be unreasonably withheld; provided further, that in no
event shall any indemnity under this Section 6 exceed the gross proceeds from
the offering received by such Investor unless the Violation is the result of
fraud on the part of such Investor.

                  (c) promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action (including any governmental
action), such indemnified party shall, if a claim in respect thereof is to be
made against any indemnifying party under this Section, 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 shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party; and provided further, that if there is more than one
indemnified party, the indemnifying party shall pay for the fees and expenses of
one counsel for any and all indemnified parties to be mutually agreed upon by
such indemnified parties, unless representation of an indemnified party by the
counsel retained by the other indemnified parties would be inappropriate due to
actual or potential differing interests between such indemnified parties. The
failure to deliver written notice to the indemnifying party within a reasonable
time of the commencement of any such action, if materially prejudicial to its
ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party under this Section, 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.


<PAGE>

                  (d) if the indemnification provided for in this Section is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any losses, claims, damages or liabilities referred to
herein, the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability 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, claim, damage or liability, as well as any other relevant equitable
considerations. 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 or alleged 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. No person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11 of the Securities Act) shall
be entitled to contribution from any person or entity who shall not have been
guilty of such fraudulent misrepresentation.

                  (e) the obligation of the Company and the Investors under this
Section shall survive the completion of any offering for resale of shares of the
Registrable Stock in the Registration Statement, and otherwise.

         7. Limitation on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of all of the Investors, enter into any agreement with any person or persons
providing for the granting to such holder of registration rights pari passu or
senior to those granted to Investors pursuant to this Agreement, or of
registration rights which might cause a reduction in the number of shares
includable by the Investors in any registration.

         8. Miscellaneous.

                  (a) The Company shall not hereafter enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Investors in this Agreement.

                  (b) Except as otherwise provided herein, the provisions of
this Agreement may not be amended, modified or supplemented, and waivers or
consents to or departures from the provisions hereof may not be given or made
unless the Company has obtained the written consent of the Investors.

                  (c) All notices and other communications provided for or
permitted hereunder shall be made by hand delivery, telex, facsimile, overnight
courier or registered first-class mail:

                  (i) if to an Investor, at the address set forth on Schedule A
         attached hereto;

                  (ii) if to the Company, at the address set forth in the
         Purchase Agreement.


<PAGE>

All such notices and communications shall be deemed to have been duly given:
when delivered, if by hand, overnight courier or mail; when the appropriate
answer back is received, if by telex; when transmission is confirmed by the
sending unit, if by facsimile.

                  (d) This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one an the same agreement.

                  (e) The headings to this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

                  (f) This Agreement shall be governed by and construed in
accordance with the laws of the State of Minnesota without giving effect to the
principles of choice or conflict of law thereof. Each of the Company and the
Investors irrevocably consent to the exclusive jurisdiction of the United States
Federal courts and state courts, located in Hennepin County, Minnesota, in any
suit or proceeding relating to, based on or arising under this Agreement and
irrevocably agree that all claims in respect of such suit or proceeding may be
determined in such courts. The Company irrevocably waives the defense of an
inconvenient forum to the maintenance of such suit or proceeding. Service of
process on the Company mailed by first class mail shall be deemed in every
respect effective service of process upon the Company in any such suit or
proceeding. Nothing herein shall affect the right of any Investor to serve
process in any manner permitted by law.

                  (g) In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of such provision in every other respect and of the
remaining provisions contained herein shall not be in any way impaired thereby,
it being intended that all of the rights and privileges of the Investors and the
Company shall be enforceable to the fullest extent permitted by law.

                  (h) The remedies provided for in this Agreement shall be
cumulative and in addition to all other remedies available, at law or in equity,
and nothing herein shall limit a holder's right to pursue actual damages for any
failure by the Company to comply with the terms of this Agreement.
