ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Pursuant to a Common Stock Purchase Agreement dated June 6, 1999
between the Issuer and Hewlett-Packard (the "Stock Purchase Agreement"),
Hewlett-Packard on June 28, 1999 acquired 1,357,143 shares of the Issuer's

working capital. A copy of the Stock Purchase Agreement is filed as exhibit 1
to this Schedule 13D and is incorporated herein by reference.

ITEM 4.           PURPOSE OF TRANSACTION.

         The purpose of the transaction was for Hewlett-Packard to make an
equity investment in the Issuer in connection with the establishment of a
long-term sales, marketing and research alliance with respect to blood
analysis products manufactured by the Issuer. Concurrently, with the
execution of the Stock Purchase Agreement, Hewlett-Packard and the Issuer
entered into a distribution agreement with respect to such alliance.

         Except as described below, Hewlett-Packard does not have any present
plan or proposal as a stockholder which relates to, or would result in any
action with respect to, the matters listed in paragraphs (b) through (j) of Item
4 of Schedule 13D. In the future, Hewlett-Packard may purchase additional
securities of the Issuer in the open market or in private transactions.

         Pursuant to the terms of the Stock Purchase Agreement, the Issuer has
agreed that during the period ending June 28, 2001 (the "Two Year Period"), it
shall not, with certain exceptions, issue any additional shares of its capital
unless (A) Hewlett-Packard has first been offered (subject to the preemptive
rights of certain other shareholders) the right to purchase such shares. In
addition, during the Two-Year Period the Issuer shall not without
Hewlett-Packard's consent issue additional shares of capital stock to any person
(other than Hewlett-Packard) in an amount which would, when aggregated with the
capital stock owned by such person, provide such person with more than 20% of
the fully diluted voting power of the Issuer.

         Under the Stock Purchase Agreement, Hewlett-Packard shall have the
right to increase its ownership in the Issuer through open market transactions
or in block transactions from existing shareholders, subject to applicable
provisions of the Minnesota Business Corporation Act, Minnesota Statutes,
Chapter 302A. To the extent the Issuer opts out of the provisions of Minnesota
Statutes, Section 302A.671 ("Control Share Acquisition Act") with respect to any
shareholder or potential shareholder of the Issuer, the Issuer shall similarly
and at the same time opt out with respect to Hewlett-Packard. During the period
ending June 28, 2002, and so long as the Hewlett-Packard owns at least three
percent of the voting power of the Issuer, the Issuer shall not implement any
shareholder rights plan or poison pill.

                  During the Two-Year Period, the Issuer shall not seek or
encourage any Takeover Proposal (as defined in the Stock Purchase Agreement)
from any person other than Hewlett-Packard unless the Issuer's board of
directors in good faith has determined, after receiving the advice of a
nationally recognized investment bank and the Issuer's outside legal counsel,
that there has been a

sustained and substantial deterioration in the Issuer's business that
requires the Issuer's board of directors to seek a sale of the business
because the Issuer lacks any other practical alternative.

                  Pursuant to the Stock Purchase Agreement, the Issuer has
agreed that the number of directors comprising its Board of directors shall be
not less than seven and not more than nine. Hewlett-Packard shall be entitled to
nominate one director to the Issuer's board of directors, except that such right
shall be suspended to the extent Hewlett-Packard's ownership falls below 3% of
the voting power of the Issuer and in that event Hewlett-Packard shall cause any
director so nominated and elected to resign. At any time Hewlett-Packard obtains
18% of the voting power of the Issuer, Hewlett-Packard shall be entitled to
nominate one additional director to the Issuer's board of directors, except such
right shall be suspended to the extent Hewlett-Packard's ownership falls below
18% of the voting power of the Issuer because of the sale of Common Stock owned
by it or otherwise falls below 15% of the voting power of the Issuer and in that
event Hewlett-Packard shall cause one of its two directors so nominated and
elected to resign. As long as Hewlett-Packard holds Common Stock having at least
18% of the voting power of the Company, Hewlett-Packard shall be entitled to
nominate that number of directors (rounded to the nearest whole) proportionate
to its voting power in the Issuer. So long as 20% or more of the Issuer's voting
power is owned by persons who are not affiliates of the Issuer or
Hewlett-Packard, the Issuer shall have at least three independent directors. If
Hewlett-Packard is entitled to nominate one or more directors, the board of
directors of the Issuer shall use its reasonable best efforts to cause such
nominee(s) to be elected to the board of directors.

         ITEM 5.  INTEREST IN SECURITIES OF THE ACT.

         The aggregate number of shares beneficially owned by Hewlett-Packard is
1,809,524 which represents 7.0% of the Issuer's outstanding Common Stock (based
upon the representation of the Issuer in the Stock Purchase Agreement that it
had 24,176,205 shares of Common Stock outstanding as of June 6, 1999).

         Hewlett-Packard has the sole power to vote the 1,809,524 shares
beneficially owned by it (including the shares that would be received upon
complete exercise of the Warrant) and has the sole power to dispose of such
shares.

         Other than the acquisition of the Shares and the Warrant as described
in this statement, there have been no transactions by Hewlett-Packard in the
Issuer's Common Stock during the past sixty days.

ITEM 6.        CONTRACTS, ARRANGEMENTS, UNDERSTANDING OR RELATIONSHIPS WITH
               RESPECT TO SECURITIES OF THE ISSUER.

(a) STOCK PURCHASE AGREEMENT

The Stock Purchase Agreement is described and/or referred to in Items 3 - 5
and is attached as Exhibit 1.

(b) WARRANT

The Warrant is referred to in Items 3 and 5 and is attached as Exhibit 2.

(c) AGREEMENTS WITH AMARFOUR LLC AND BCC ACQUISITION II LLC

As an inducement for Hewlett-Packard to enter into the Stock Purchase
Agreement and to consummate the transactions contemplated thereby, certain
shareholders of the Issuer, Amarfour LLC ("Amarfour") and BCC Acquisition II
LLC ("BCC"), have each entered into separate letter agreements with
Hewlett-Packard as contemplated by Section 9.9 of the Stock Purchase
Agreement. The letter agreement between Amarfour and Hewlett-Packard is
attached as Exhibit 3 and the letter agreement between BCC and
Hewlett-Packard is attached as Exhibit 4. Pursuant to such letter agreements,
Amarfour and BCC have each undertaken that, upon Hewlett-Packard's request,
they will enter into separate agreements with Hewlett-Packard with respect to
the matters set forth in Section 9.9 of the Stock Purchase Agreement. As a
result of such undertakings, and subject to Hewlett-Packard obtaining
ownership of shares representing 12% or more of the voting power of the
Issuer, Amarfour and BCC shall be obligated, at Hewlett-Packard's election,
to not transfer "in block" any shares, warrants, options or convertible
securities in the Issuer (except to their majority controlled financial
investor affiliates) unless they have first offered Hewlett-Packard the right
to purchase such shares, warrants, options or convertible securities under
terms and conditions no less favorable to Hewlett-Packard than as proposed to
be offered to any third party. For purposes of the preceding sentence, "in
block" shall mean (1) shares, warrants, options or convertible securities
representing 5% or more of the fully diluted voting power of the Issuer and
(2) with respect to transferees who (prior to the proposed transfer) are 5%
shareholders, shares, warrants, options or convertible securities
representing the lower of 3% of the fully diluted voting power of the Issuer
or that amount which would cause such transferee to hold more than 9% of the
fully diluted voting power of the Issuer. The above described transfer
restrictions shall only be effective during the Two-Year Period and shall be
suspended at such times, if any, during the Two-Year Period that
Hewlett-Packard's voting power in the Issuer falls below (a) 12% due to
transfer of the Issuer's equity by Hewlett-Packard and/or (b) 10% for any
other reason.

NOW, THEREFORE, in consideration of the mutual covenants contained in this
Agreement, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Purchaser
hereby agree as follows:

SECTION 1. AUTHORIZATION AND ISSUANCE OF THE SECURITIES. Subject to the terms

delivery to the Purchaser of 1,357,143 shares of its Common Stock (the

<PAGE>

3.2 DELIVERY OF THE SHARES AND THE WARRANTS. At the Closing, the Company

Also at the Closing, the Purchaser shall pay to the Company the Price.

SECTION 4. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. Except as set forth
on the Schedule of Exceptions attached hereto as EXHIBIT B, the Company
hereby represents and warrants as of the date hereof to the Purchaser as
follows:

4.1 ORGANIZATION AND STANDING. Each of the Company and its Subsidiary (as
hereinafter defined in this Section 4.1) has been duly incorporated and is
validly existing as a corporation in good standing under the laws of the
jurisdiction of its organization, has full corporate power and authority to own
or lease its properties and conduct its business as presently conducted, and is
duly qualified as a foreign corporation and is in good standing in all
jurisdictions in which the character of the property owned or leased or the
nature of the business transacted by it makes qualification necessary (except
where the failure to be so qualified would not have a material adverse effect on
the business, properties, financial condition or results or operations of the
Company or its Subsidiary). Other than Diametrics Medical, Ltd., formerly known
as Biomedical Sensors, Ltd., (the "Subsidiary"), the Company has no subsidiaries
or equity interest in any other entity.

4.2 CORPORATE POWER; AUTHORIZATION. The Company has all requisite corporate
power, and has taken all requisite corporate action, to execute and deliver this
Agreement and the Warrants, to sell and issue the Shares and the Warrants, to
issue the shares issuable upon exercise of the Warrants (the "Warrant Shares")
and to carry out and perform all of its obligations hereunder and thereunder.
Each of this Agreement and the Warrants constitutes the legal, valid and binding
obligation of the Company, enforceable in accordance with its terms, except (i)
as limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws relating to or affecting the enforcement of creditors' rights
generally, (ii) as limited by equitable principles generally, and (iii) as
rights to indemnity or contributions hereunder may be limited by federal or
state securities laws or principles of public policy. The execution and delivery
of this Agreement and the Warrants do not, and the performance of this Agreement
and the Warrants and the compliance with the provisions hereof and thereof and
the issuance, sale and delivery of the Shares, the Warrants and the Warrant
Shares by the Company will not, conflict with, or result in a breach or
violation of the terms, conditions or provisions of, or constitute a default
under, or result in the creation or imposition of any lien pursuant to the terms
of, the Articles of Incorporation or Bylaws of the Company or any statute, law,
rule or regulation applicable to the Company or its Subsidiary, or any state or
federal order, judgment or decree applicable to the Company or its Subsidiary,
or any indenture, mortgage, lease or other agreement or instrument to which the
Company or its Subsidiary or any of the properties of such person is subject,
except such as would not have a material adverse effect on the business,
properties, financial condition or results of operations of the Company or its
Subsidiary.

4.3 ISSUANCE AND DELIVERY OF THE SHARES AND WARRANT SHARES; GRANT OF THE
WARRANTS. The Shares, when issued and paid for in compliance with the provisions
of this Agreement, will be validly issued, fully paid and nonassessable and
issued in compliance with all applicable federal and state securities laws.
Further, the Shares, when issued and paid for in compliance with the provisions
of this Agreement, will not be subject to preemptive, co-sale, right of first
refusal or any other similar rights of the shareholders of the Company or any
liens or encumbrances. In addition, the Warrant Shares when issued and paid for
in accordance with the terms of the Warrants will be validly issued, fully paid
and nonassessable, and will not be subject to preemptive, co-sale, right of
first refusal or any other similar rights of the shareholders of the Company or
any liens or encumbrances, other than those created by the Purchaser or arising
under federal or state securities laws. The Company has not granted any
registration rights which are still in effect with respect to its securities
other than the registration rights set forth herein. Issuance of the Shares, the
Warrants and the Warrant Shares or any of them does not and will not constitute
a default under or give rise to a right of termination, cancellation,
restriction or acceleration of any right or obligation of the Company or its
Subsidiary or a loss of any benefit to which the Company or its Subsidiary is
entitled under any provision of any agreement, contract or other instrument
binding upon or applicable to the Company or its Subsidiary or any of the
properties, assets, licenses, franchises, permits or other similar
authorizations of either of them.

4.4 SEC DOCUMENTS; FINANCIAL STATEMENTS. The Company has filed in a timely
manner all documents that it was required to file with the Securities and
Exchange Commission ("SEC") under Sections 13, 14(a) and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), during the 36 months
preceding the date of this Agreement. As of their respective filing dates (or,
if amended, when amended), all documents filed by the Company with the SEC,
whether under the Exchange Act or under the Securities Act of 1933, as amended
(the "Securities Act"), during such 36-month period (the "SEC Documents")
complied in all material respects with the requirements of the Exchange Act or
the Securities Act, as the case may be. None of the SEC Documents as of their
respective dates contained any untrue statement of material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances under which they were
made, not misleading. The consolidated financial statements of the Company and
its Subsidiary included in the SEC Documents (the "Financial Statements") comply
as to form in all material respects with applicable accounting requirements and
with the published rules and regulations of the SEC with respect thereto. The
Financial Statements have been prepared in accordance with generally accepted
accounting principles consistently applied and fairly present the consolidated
financial position of the Company and its Subsidiary at the dates thereof and
the results of their operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal, recurring adjustments
and the absence of footnotes). There is no material liability or commitment of
the Company or its Subsidiary that is required to be reflected in the Financial
Statements which is not reflected in the most recent Financial Statements except
commitments made since the date of such Financial Statements in the ordinary
course of business. There have not been any changes in the assets, liabilities,
financial condition or operations of the Company or its Subsidiary from those
reflected in the most recent Financial Statements, except changes in the
ordinary course of business that have not had and are not reasonably expected to
have a


                                       3
<PAGE>


material adverse effect on the business, properties, financial condition
or results of operations of the Company or its Subsidiary.

4.5 INTELLECTUAL PROPERTY. (a) Each of the Company and its Subsidiary has
sufficient title and ownership of all material patents, patent rights,
inventions, trademarks, service marks, copyrights, trade secrets, proprietary
rights, processes and know-how (collectively, "Intellectual Property") owned or
used by it or that are necessary for the conduct of its business as presently
conducted and believes it can obtain, on commercially reasonable terms, any
additional rights necessary for its business as proposed to be conducted, and
the Intellectual Property does not, and will not, conflict with or constitute an
infringement of the rights of others;

    (b) There are no outstanding options, licenses (whether to or from the
Company) or agreements of any kind relating to the Intellectual Property
described in paragraph (a) of this Section 4.5 or granting rights to any
other person to manufacture, license, produce, assemble, market or sell
products or services derived or derivable from the Intellectual Property of
the Company or its Subsidiary, nor is the Company or its Subsidiary bound by
or a party to any options, licenses or agreements of any kind with respect to
the Intellectual Property of any other person or entity;

    (c) Neither the Company nor its Subsidiary has received any
communications alleging that such person or any of its employees has violated
or infringed or, by conducting its business as proposed, would violate or
infringe, any of the Intellectual Property of any other person or entity;

    (d) Neither the Company nor its Subsidiary is aware that any of its
employees is 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 interfere
with the use of such employee's best efforts to promote the interests of the
Company or its Subsidiary with respect to the Intellectual Property of the
Company or its Subsidiary or otherwise or that would conflict with the
business of the Company or its Subsidiary as proposed to be conducted; and

    (e) Neither the execution nor delivery of this Agreement, nor the
carrying on of the business of the Company or its Subsidiary by the employees
of such person, nor the conduct of the business of the Company or its
Subsidiary as proposed, will, to the Company's knowledge, conflict with or
result in a breach of the terms, conditions, or provisions of, or constitute
a default under, any contract, covenant, or instrument under which any of
such employees is now obligated. The Company does not believe it is or will
be necessary to utilize any inventions of any of the employees of the Company
or its Subsidiary (or people such person currently intends to hire) made
prior to their employment by such person.

4.6 PROPERTIES. The Company and its Subsidiary have good and valid title to all
of the properties and assets reflected as owned by the Company or its Subsidiary
in the Financial Statements, free and clear of all material liens, mortgages
(statutory or otherwise), security interests, pledges, claims or encumbrances
except those, if any, disclosed in the Financial Statements. The Company and its
Subsidiary hold their leased properties under valid and


                                      4
<PAGE>


binding leases, with such exceptions as are not materially significant in
relation to the business of the Company or its Subsidiary. The Company and
its Subsidiary own or lease all of such properties as are necessary to its
operations as now conducted.

4.7 CAPITALIZATION. The authorized capital stock of the Company consists of
35,000,000 shares of Common Stock and 5,000,000 shares of preferred stock. There
are 24,176,205 shares of Common Stock and no shares of Preferred Stock
outstanding as of the Effective Date, and, excluding the exercise of vested
options and warrants outstanding at the discretion of the holder thereof and
shares purchased through the Company's existing employee stock purchase plan,
immediately prior to the Closing, 24,176,205 shares of Common Stock and no
shares of Preferred Stock will be outstanding. The certificates evidencing the
Shares and the Warrant Shares will be in due and proper legal form and will be
duly authorized for issuance by the Company. All of the issued and outstanding
securities of the Company have been duly authorized and validly issued, are
fully paid and nonassessable, have been issued in compliance with federal, state
and other applicable laws and were issued without violation of any preemptive,
co-sale or other right. Except as otherwise disclosed in the SEC Documents and
in the Financial Statements, there is no outstanding option, warrant, agreement
or other right calling for the issuance or redemption of, and there is no
commitment, plan or arrangement to issue or redeem, any securities of the
Company. The Company does not have any binding agreement with respect to the
acquisition or purchase of the securities of or owned by any person or entity or
the acquisition of the business, assets or liabilities of any person or entity,
and the Company does not have any agreement or understanding with respect to the
disposition or sale of its business, or any of its material assets or property.

4.8 LITIGATION. There is no pending or, to the Company's knowledge, threatened,
action, suit or other proceeding to which the Company or its Subsidiary is a
party or to which the property or assets of the Company or its Subsidiary is
subject which might result in a material adverse effect on the business,
properties, financial condition or results of operations of the Company or its
Subsidiary.

4.9 NO DEFAULTS. Neither the Company nor its Subsidiary is in violation or
default of any provisions of its Articles of Incorporation or Bylaws, or any
organizational documents, or in breach with respect to any provision of any
agreement, judgment, decree, order, mortgage, deed of trust, lease franchise,
license, indenture, permit or other instrument to which it is a party or by
which it or any of its properties are bound which violation, default or breach
would have a material adverse effect on the business, properties, financial
condition or results of operations of the Company or its Subsidiary, and there
does not exist any state of facts which constitutes an event of default on the
part of the Company or its Subsidiary as defined in such documents or which,
with notice or lapse of time or both, would constitute such an event of default.

4.10 MATERIAL AGREEMENTS. Each of the Company and its Subsidiary is a party to
all agreements that are necessary for the conduct of the business of such person
as presently conducted and all such agreements are currently in effect. Neither
the Company nor its Subsidiary is in breach of any provision of any such
agreement where such breach would have a material adverse effect on the
business, properties, financial condition or results of operations of the
Company or its Subsidiary.

form under the United States Hart-Scott-Rodino Antitrust Improvements Act of

federal, state, local, and foreign income and franchise tax returns and has paid
or accrued all taxes shown as due thereon except for such taxes as are being
contested in good faith, and the Company has no knowledge of any tax deficiency
which has been or might be asserted or threatened against the Company or its

Subsidiary.

Company and the Purchaser.

SECTION 5. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser hereby
represents and warrants as of the date hereof to the Company as follows:

5.1 INVESTMENT PURPOSES.

          (a) The Purchaser acknowledges that the Shares and the Warrants are
being issued in reliance upon the exception from the registration requirements
of the Securities Act provided by Section 4(2) thereof and as such the Shares
and the Warrants will be "restricted securities" within the meaning of Rule 144.

          (b) The Purchaser is acquiring the Shares and the Warrants pursuant to
this Agreement in the ordinary course of its business and for its own account
for investment only and with no present intention of distributing any of such
Shares or Warrants or any arrangement or understanding with any other persons
regarding the distribution of such Shares or Warrants except in each case as
conforms with all applicable requirements of the Securities Act, applicable blue
sky laws and all rules and regulations promulgated thereunder.

          (c) The Purchaser will not, directly or indirectly, offer, sell,
pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase
or otherwise acquire or take a pledge of) any of the securities purchased
hereunder except in compliance with the Securities Act, applicable blue sky
laws, and the rules and regulations promulgated thereunder.

          (d) The Purchaser has, in connection with its decision to acquire the
Shares and the Warrants, relied with respect to the Company and its affairs
solely upon the SEC Documents and the other information delivered to the
Purchaser by the Company as described in Section 4.4 above and the
representations and warranties of the Company contained herein.

          (e) The Purchaser is an "accredited investor" within the meaning of
Rule 501 of Regulation D promulgated under the Securities Act.

          (f) The Purchaser has full right, power, authority and capacity to
enter into this Agreement and to consummate the transactions contemplated hereby
and has taken all necessary action to authorize the execution, delivery and
performance of this Agreement. Upon the execution and delivery of this Agreement
by the Purchaser, this Agreement shall constitute a valid and binding obligation
of the Purchaser, enforceable in accordance with its terms, except (i) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws relating to or affecting the enforcement of creditors' rights
generally, (ii) as limited by equitable principles generally, including any
specific performance, and (iii) as to those provisions of Section 10 relating to
indemnity or contribution.

5.2 NO ADVICE. The Purchaser understands that nothing in this Agreement or any
other materials presented to the Purchaser in connection with the acquisition of
the Shares and the Warrants constitutes legal, tax or investment advice to the
Purchaser. The Purchaser has consulted such legal, tax and investment advisors
as it, in its sole discretion, has deemed necessary or appropriate in connection
with its purchase of the Shares and the Warrants.


                                       7
<PAGE>


5.3 RESTRICTION ON TRANSFER. The Purchaser understands that: (a) other than to a
person directly or indirectly controlling, controlled by, or in common control
with, the Purchaser (any such person, an "Affiliate"), neither the Shares nor
the Warrants will be transferable in the absence of a registration under the
Securities Act or an exemption therefrom or in the absence of compliance with
any term of this Agreement; (b) the Company may provide stop transfer
instructions to its transfer agent with respect to the Shares and the Warrants
in order to enforce the restrictions contained in this Section 5.3 and (c) each
certificate representing Shares shall be in the name of the Purchaser and shall
bear substantially the following legend:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "SECURITIES ACT"), OR REGISTERED OR QUALIFIED UNDER THE SECURITIES
          LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY ONLY BE SOLD,
          PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF BY PURCHASER IF
          SUBSEQUENTLY REGISTERED UNDER THE SECURITIES ACT AND REGISTERED OR
          QUALIFIED UNDER ANY APPLICABLE STATE OR OTHER SECURITIES LAWS, UNLESS
          THE COMPANY DETERMINES THAT EXEMPTION FROM SUCH REGISTRATION
          REQUIREMENT IS AVAILABLE."

5.4 BROKER'S FEE. The Purchaser represents that there are no brokers or finders
entitled to compensation by the Purchaser in connection with any of the
transactions referred to herein or contemplated hereby, and shall indemnify the
Company for any such fees for which the Purchaser is responsible.

SECTION 6. COVENANTS OF THE PARTIES.

6.1 ACCESS TO INFORMATION. For a period beginning on the Effective Date and
continuing until the Closing, the Company shall afford to the Purchaser and its
agents and representatives full access, at reasonable times and in a reasonable
manner, to all of its premises, facilities, properties, books and records and
shall make its directors, officers, agents reasonably available to confer with
the Purchaser and its agents and representatives. The Purchaser shall have the
right to make copies, extracts and summaries of all such reports, books, records
and information, subject, however, to any obligations of the Company to any
other persons. The Company shall notify the Purchaser of any material change in
the business of the Company or in its operations or properties, or of any
governmental complaints, investigations or hearings (or communications
indicating the same may be contemplated) or of the institution, continuation or
threat of any litigation involving the Company or any affiliate of the Company
or any of its assets, and will keep the Purchaser informed of such events.

6.2 MAINTENANCE OF LISTING. For so long as the Company is obligated to register
Registrable Securities as provided in Section 10, the Company will use its
reasonable best efforts to maintain its listing on The Nasdaq National Market or
a national securities exchange, as defined in the Exchange Act.

6.3 FILINGS. The parties shall consult and fully cooperate with and provide
assistance to each other in preparing and filing as soon as practicable all
consents, approvals and authorizations


                                     8
<PAGE>

necessary or advisable to be made or obtained from any third party or
governmental agency in order to consummate the transactions contemplated
hereby.

6.4 PURCHASE RIGHT. During the period ending on the date two years after the
Closing Date (the "Two-Year Period"), the Company shall not issue any
additional shares of Common Stock or preferred stock (other than pursuant to
(1) employee/director compensation plan(s), including options, approved by a
majority of the independent directors of the Company, (2) options, warrants
and convertible debt outstanding on the Effective Date, (3) warrants granted
in connection with commercially standard credit/financing arrangements
approved by a majority of the board of directors and exercisable, in
aggregate, into no more than the number of shares representing 5% of the
outstanding Common Stock on the Effective Date and (4) after complying with
the provisions of Sections 6.7 and 6.8, lock-up or option agreements in
connection with a definitive acquisition agreement referred to in Section 6.7
and 6.8) unless (A) the Purchaser has first been offered (subject to the
preemptive rights of the "Purchasers" under the Preferred Stock Purchase
Agreement referred to in Section 9.6 to maintain their pro rata ownership in
the Company) the right to purchase such shares (i) under terms and conditions
at least as favorable to the Purchaser as those proposed to be offered to any
third party or (ii) if such shares are proposed to be sold in an underwritten
public offering, under terms and conditions at least as favorable to the
Purchaser as those proposed to be offered in the public offering and (B) the
Purchaser does not accept such offer within ten-business days after the date
of such offer. In addition, during the Two-Year Period the Company shall not
without the Purchaser's consent issue additional shares of Common Stock or
preferred stock to any person (other than the Purchaser) in an amount which
would, when aggregated with the Common Stock or preferred stock owned by such
person, provide such person with more than 20% of the fully diluted voting
power of the Company. For the purposes of this Agreement, (i) "voting power"
means the ownership of shares of capital stock of the Company entitling the
holder to vote for the election of directors generally, (ii) any calculation
of the percentage of "voting power" shall be based (both in the numerator and
denominator) on the number of shares possessing such voting power actually
outstanding without regard to warrants, options or convertible securities and
(iii) any calculation of the percentage of "fully diluted voting power" shall
be based (both in the numerator and denominator) on the number of shares
possessing such voting power that would be outstanding giving effect to the
exercise or conversion of warrants, options and convertible securities.

6.5 OPEN MARKET PURCHASES. The Purchaser shall have the right to increase its
ownership in the Company through open market transactions or in block
transactions from existing shareholders, subject to applicable provisions of the
Minnesota Business Corporation Act, Minnesota Statutes, Chapter 302A. To the
extent the Company opts out of the provisions of Minnesota Statutes, Section
302A.671 ("Control Share Acquisition Act") with respect to any shareholder or
potential shareholder of the Company, the Company shall similarly and at the
same time opt out with respect to the Purchaser.

6.6 CHANGE OF CONTROL. During the period ending three years after the Closing
Date, and so long as the Purchaser owns at least three percent of the voting
power of the Company, the Company shall not implement any shareholder rights
plan or poison pill.


                                       9
<PAGE>


6.7 NON-SOLICITATION. During the Two-Year Period, the Company shall not seek or
encourage any Takeover Proposal from any person other than the Purchaser unless
the Company's board of directors in good faith has determined, after receiving
the advice of a nationally recognized investment bank and the Company's outside
legal counsel, that there has been a sustained and substantial deterioration in
the Company's business that requires the Company's board of directors to seek a
sale of the business because the Company lacks any other practical alternative
(a "Required Sale Situation"). For purposes of this Agreement, "Takeover
Proposal" means any proposal for a merger (other than a reincorporation or
reorganization which does not change the outstanding ownership of the Company)
or business combination of the Company or any of its Subsidiaries or any
proposal or offer to acquire in any manner, directly or indirectly, a 33% or
greater equity interest in, a 33% or greater portion of the voting securities
of, or a 33% or greater portion of the assets of the Company and its
Subsidiaries taken as a whole. If a Takeover Proposal (the "First Proposal") is
presented during a Required Sale Situation, the Company shall provide the
Purchaser with the details of the First Proposal (including price, terms and the
identity of the offeror) and ten-business days to respond with a counter
proposal before the Company may accept the First Proposal or enter into any
lock-up/break-up agreement with respect thereto. If the Purchaser agrees to meet
the First Proposal (as to price and terms) within such initial ten-business day
period, then the Company may, for an additional ten-business day period
thereafter, solicit a superior proposal (based on price and terms) (the "Second
Proposal") to the First Proposal. In the event that a Second Proposal is
presented within such second ten-business day period, the Company shall provide
the Purchaser with the details of the Second Proposal (including price, terms
and the identity of the offeror). The Company may not accept such Second
Proposal (or enter into any lock-up/break-up agreement with respect thereto)
during an additional ten-business day period. If the Purchaser offers a superior
proposal (based on price and terms) to the Second Proposal (the "Topping Bid")
within such third ten-business day period, the Company shall enter into a
definitive acquisition agreement with the Purchaser on the basis of such Topping
Bid, which definitive agreement shall not provide for a "superior
offer/fiduciary out" and shall require, at the Purchaser's election, a
shareholder vote even in the face of a subsequent competing offer, unless
otherwise prohibited by law. If the Purchaser fails to offer a Topping Bid
within such third ten-business day period, the Company may accept the Second
Proposal. If the Company is permitted to accept a First Proposal or a Second
Proposal but fails to consummate the transaction contemplated thereby within 180
days after it is permitted to accept such Proposal, the provisions of this
Section 6.7 shall be once again complied with AB INITIO. Any definite
acquisition agreement entered into pursuant to the First Proposal or the Second
Proposal need not provide for a "superior offer/fiduciary out" and may require a
shareholder vote even in the face of a subsequent competing offer, unless
otherwise prohibited by law.

6.8 THIRD-PARTY UNSOLICITED OFFER. If during the Two-Year Period a person other
than the Purchaser presents the Company with any unsolicited Takeover Proposal
(the "First Proposal"), the Company shall provide the Purchaser with the details
of the First Proposal (including price, terms and the identity of the offeror)
and ten-business days to respond with a counter proposal before the Company may
accept the First Proposal or enter into any lock-up/break-up agreement with
respect thereto. If the Purchaser agrees to meet the First Proposal (as to price
and terms) within such initial ten-business day period, then the Company may,
for an additional ten-business day period thereafter, solicit a superior
proposal (based on price and terms) (the


                                     10
<PAGE>


"Second Proposal") to the First Proposal. In the event that a Second Proposal
is presented within such second ten-business day period, the Company shall
provide the Purchaser with the details of the Second Proposal (including
price, terms and the identity of the offeror). The Company may not accept
such Second Proposal (or enter into any lock-up/break-up agreement) during an
additional ten-business day period. If the Purchaser offers a superior offer
(based on price and terms) to the Second Proposal (the "Topping Bid") within
such third ten-business day period, the Company shall enter into a definitive
acquisition agreement (including appropriate lock-up/break-up agreement) with
the Purchaser on the basis of such Topping Bid and such agreement shall not
provide for a "superior offer/fiduciary out" and shall require, at the
Purchaser's election, a shareholder vote even in the face of a subsequent
competing offer, unless otherwise prohibited by law. If the Purchaser fails
to offer a Topping Bid within such third ten-business day period, the Company
may accept the Second Proposal. If the Company is permitted to accept a First
Proposal or a Second Proposal but fails to consummate the transaction
contemplated thereby within 180 days after it is permitted to accept such
Proposal, the provisions of this Section 6.8 shall be once again complied
with AB INITIO. Any definite acquisition agreement entered into pursuant to
the First Proposal or the Second Proposal need not provide for a "superior
offer/fiduciary out" and may require a shareholder vote even in the face of a
subsequent competing offer, unless otherwise prohibited by law.

6.9 BREAK-UP FEE/TERMINATION. If the Purchaser agrees to meet a First Proposal
under Section 6.7 or 6.8 above (but does not provide a Topping Bid) and the
Company enters into a definitive acquisition agreement with a third party within
180 days of the expiration of the Two-Year Period, the Company shall pay the
Purchaser 3% of the value of the transaction. The provisions of Section 6.7 and
6.8 shall terminate and be of no further force unless the Purchaser owns 14% of
the voting power of the Company by the close of business on November 30, 2000.

6.10 GOVERNANCE. The number of directors comprising the Company Board of
Directors shall be not less than seven and not more than nine. The Purchaser
shall be entitled to nominate one director to the Company's Board of Directors,
except that such right shall be suspended to the extent the Purchaser's
ownership falls below 3% of the voting power of the Company and in that event
the Purchaser shall cause any director so nominated and elected to resign. At
any time the Purchaser obtains 18% of the voting power of the Company, the
Purchaser shall be entitled to nominate one additional director to the Company's
Board of Directors, except such right shall be suspended to the extent the
Purchaser's ownership falls below 18% of the voting power of the Company because
of the sale of Common Stock owned by it or is otherwise falls below 15% of the
voting power of the Company and in that event the Purchaser shall cause one of
its two directors so nominated and elected to resign. As long as the Purchaser
holds Common Stock having at least 18% of the voting power of the Company, the
Purchaser shall be entitled to nominate that number of directors (rounded to the
nearest whole) proportionate to its voting power in the Company. So long as 20%
or more of the Company's voting power is owned by persons who are not affiliates
of the Company or the Purchaser, the Company shall have at least three
independent directors. If the Purchaser is entitled to nominate one or more
directors, the board of directors of the Company shall use its reasonable best
efforts to cause such nominee(s) to be elected to the board of directors.

<PAGE>


7.1 SURVIVAL. Notwithstanding any investigation made by any party to this
Agreement, all covenants, agreements, representations and warranties made by the
Company and the Purchaser herein and in the certificates for the securities
delivered pursuant hereto shall survive the execution of this Agreement, the
delivery to the Purchaser of the certificates representing the Shares and the
Warrants, and the payment thereof, until the fifth anniversary of the Closing
Date, except for the representations set forth in Section 4.2, 4.7 and 4.16 and
the representations set forth in the first three sentences of Section 4.3, which
shall survive indefinitely, and the representations as to taxes set forth in
Section 4.14, which shall survive for the longer of (i) the fifth anniversary of
the Closing Date and (ii) the period expiring 90 days after the expiration of
the period during which a claim by the applicable taxing authority for a
deficiency or other tax adjustment would not be barred by the statute of
limitations applicable to such taxes (any such period an "Indemnity Period").

7.2 PURCHASER'S RIGHT TO INDEMNIFICATION. Subject to the provisions of this
Section 7, the Company hereby agrees to indemnify and hold harmless the
Purchaser and the employees, agents, directors, officers, equity holders,
successors, predecessors, assigns and affiliates of any of them (collectively,
the "Purchaser Indemnified Parties") from and against (i) any and all losses,
obligations, liabilities, damages, claims, deficiencies, costs and expenses
(including, but not limited to, the amount of any settlement entered into
pursuant hereto and all reasonable legal and other expenses incurred in
connection with the investigation, prosecution or defense of the matter but
excluding consequential damages) (collectively, "Claims"), which may be asserted
against or sustained or incurred by the Purchaser Indemnified Parties in
connection with, arising out of, or relating to (A) any breach or alleged breach
of any of the representations, warranties, agreements and covenants made by the
Company herein or in any certificate or other document delivered to any
Purchaser Indemnified Party by or on behalf of the Company in connection with
this Agreement; or (B) any false, incorrect or misleading representation or
warranty made by or on behalf of the Company herein or in any certificate or
other document delivered to any Purchaser Indemnified Party by or on behalf of
the Company in connection with this Agreement; and (ii) any and all costs and
expenses (including, but not limited to, reasonable legal expenses) incurred by
any Purchaser Indemnified Party in connection with the enforcement of its rights
under this Agreement. No claim for indemnification pursuant to this Section 7
may be commenced after the relevant Indemnity Period; PROVIDED, HOWEVER, that
claims made within such Indemnity Period shall survive to the extent of the
Claim covered thereby until such Claim is finally determined and, if applicable,
paid. The parties to this Agreement acknowledge that such indemnification
provisions apply only with respect to the Shares, the Warrants, the Warrant
Shares and the shares of Common Stock issued or issuable as dividends on, or
other distributions with respect to the Shares, the Warrants and the Warrant
Shares; and any other security issued or issuable in exchange for, or in
replacement of, the Shares, the Warrants and the Warrant Shares.

7.3 PROCEDURE FOR CLAIMS.

          (a) Promptly, but in any event within 10 days after obtaining
knowledge of any claim or demand which may give rise to, or could reasonably
give rise to, a claim for indemnification hereunder (an "Indemnification
Claim"), the Purchaser, to the extent it desires to be indemnified for any
claims for any such claim or demand, shall give written notice to the Company
of such


                                      12
<PAGE>


Indemnification Claim ("Notice of Claim"). A Notice of Claim shall be given
with respect to all Indemnification Claims; PROVIDED, HOWEVER, that the failure
to give a timely Notice of Claim to the Company shall not relieve the Company
from any liability that it may have to the Purchaser Indemnified Parties
hereunder to the extent that the Company is not prejudiced by such failure. The
Notice of Claim shall set forth the amount (or a reasonable estimate) of the
loss, damage or expense suffered, or which may be suffered, by the Purchaser
Indemnified Party as a result of such Indemnification Claim and the aggregate
amount of all Indemnification Claims to date and a brief description of the
facts giving rise to such Indemnification Claim. The Purchaser shall furnish to
the Company such information (in reasonable detail) as the Purchaser may have
with respect to such Indemnification Claim (including copies of any summons,
complaint or other pleading which may have been served on it and any written
claim, demand, invoice, billing or other document evidencing or asserting the
same).

          (b) If the claim or demand set forth in the Notice of Claim is a claim
or demand asserted by a third party (a "Third Party Claim"), the Company shall
have fifteen days (or such shorter period (but not less than ten days) if any
answer or other response or filing with respect to the pleadings served by the
third party is required prior to the fifteenth day) after the date of receipt by
the Company of the Notice of Claim (the "Notice Date") to notify the Purchaser
in writing of the election by the Company to defend the Third Party Claim on
behalf of the Purchaser Indemnified Parties.

          (c) If the Company elects to defend a Third Party Claim on behalf of
the Purchaser Indemnified Parties, the Purchaser shall make available to the
Company and its agents and representatives all records and other materials in
the Purchaser's possession which are reasonably required in the defense of the
Third Party Claim and the Company shall pay any expenses payable in connection
with the defense of the Third Party Claim as they are incurred (whether incurred
by the Purchaser or the Company).

          (d) If the Company has assumed control of the defense, the Company may
contest or settle the Third Party Claim on such terms as the Company may choose,
PROVIDED, HOWEVER, that the Company will not have the right, without the prior
written consent of the Purchaser, to settle any such claim if such settlement
(i) arises from or is part of any criminal action, suit or proceeding (ii)
contains a stipulation to, confession of judgment with respect to, or admission
or acknowledgment of, any liability or wrongdoing on the part of any Purchaser
Indemnified Party, (iii) relates to any foreign federal, state or local tax
matters, (iv) provides for injunctive relief, or other relief other than
damages, which is binding on any Purchaser Indemnified Party, (v) does not fully
release all Purchaser Indemnified Parties with respect to the relevant Third
Party Claim or (vi) has any res judicata or collateral estoppel effect that
could be adverse to any Purchaser Indemnified Party.

          (e) If the Company elects to defend a Third Party Claim, the Purchaser
Indemnified Parties shall have the right to participate in the defense of the
Third Party Claim, at the Purchaser Indemnified Parties' expense (and without
the right to indemnification for such expense under this Agreement); PROVIDED,
HOWEVER, that the reasonable fees and expenses of counsel retained by the
Purchaser Indemnified Parties shall be at the expense of the Company if (A) the
use of the counsel chosen by the Company to represent the Purchaser Indemnified
Parties would present


                                    13
<PAGE>


such counsel with a conflict of interest; (B) the parties to such proceeding
include both Purchaser Indemnified Parties and the Company and there may be
legal defenses available to Purchaser Indemnified Parties which are different
from or additional to those available to the Company; (C) within ten days
after being advised by the Company of the identity of counsel to be retained
to represent the Purchaser Indemnified Parties, the Purchaser Indemnified
Party affected by such claim shall have objected to the retention of such
counsel for valid reasons (which shall be stated in a written notice to the
Company), and the Company shall not have retained different counsel
reasonably satisfactory to the Purchaser Indemnified Party; or (iv) the
Company shall authorize the Purchaser Indemnified Parties to retain separate
counsel at the expense of the Company.

          (f) If the Company elects to defend a Third Party Claim, and does not
defend a Third Party Claim in good faith, the Purchaser Indemnified Parties
shall have the right, in addition to any other right or remedy it may have
hereunder, at the sole and exclusive expense of the Company, to defend such
Third Party Claim; PROVIDED, HOWEVER, that such expenses shall be payable by the
Company only if and when such Third Party Claim becomes payable.

          (g) The Purchaser shall cooperate with the Company in the defense of
Third Party Claims. Subject to the foregoing, (i) the Purchaser Indemnified
Parties shall not have any obligation to participate in the defense of or to
defend any Third Party Claim and (ii) the Purchaser Indemnified Parties' defense
of or participation in the defense of any Third Party Claim shall not in any way
diminish or lessen the right to indemnification as provided in this Section 7.

shall enter into agreements with Purchaser that provide that when Purchaser
owns shares representing 12% or more of the voting power of the Company, they
will not transfer "in block" any shares, warrants, options or convertible
securities in the Company (except to their majority controlled financial
investor affiliates) unless they have first offered the Purchaser the right
to purchase such shares, warrants, options or convertible securities under
terms and conditions no less favorable to the Purchaser than as proposed to
be offered to any third party. For purposes of the preceding sentence, "in
block" shall mean (1) shares, warrants, options or convertible securities
representing 5% or more of the fully diluted voting power of the Company and
(2) with respect to transferees who (prior to the proposed transfer) are 5%
shareholders, shares, warrants, options or convertible securities
representing the lower of 3% of the fully diluted voting power of the Company
or that amount which would cause such transferee to hold more than 9% of the
fully diluted voting power of the Company. The agreements shall also provide
that if Purchaser sells or otherwise transfers shares of the Company such
that its voting power represents less than 12% of the voting power of the
Company or if the Purchaser is diluted such that its voting power represents
less than 10% of the voting power of the Company, then such transfer
restrictions shall be suspended. Fully diluted voting power shall have the
meaning provided in Section 6.4.

SECTION 10. REGISTRATION OF THE SHARES; COMPLIANCE WITH THE SECURITIES ACT.

10.1 DEFINITIONS. As used in this Section 10, the following terms shall have the
following meanings:

          (a) "Commission" shall mean the Securities and Exchange Commission, or
any other federal agency at the time administering the Securities Act.

          (b) "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, or any similar federal statute and the rules and regulations
thereunder, all as the same shall be in effect at the time.


                                     16
<PAGE>


          (c) "Register," "registered" and "registration" shall refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act, and the declaration or ordering of the
effectiveness of such registration statement, and compliance with applicable
state securities laws.

          (d) "Registrable Securities" shall mean (i) the Shares, (ii) the
Warrant Shares, (iii) other shares of the Company purchased by Purchaser so
long as Purchaser is deemed an affiliate of the Company and provided that
such shares shall only be deemed Registrable Securities if they are included
in a registration statement together with at least 33-1/3% of the Shares, and
(iv) stock issued in respect of the stock referred to in (i), (ii) or (iii)
as a result of a stock split, stock dividend, recapitalization or
combination. Notwithstanding the foregoing, Registrable Securities shall not
include otherwise Registrable Securities (i) sold to or through a broker or
dealer or underwriter in a public distribution or a public securities
transaction, (ii) sold in a transaction exempt from the registration and
prospectus delivery requirements of the Securities Act under Section 4(1)
thereof or (iii) the registration rights associated with such securities have
been terminated pursuant to Section 10.9 of this Agreement.

          (e) "Securities Act" shall mean the Securities Act of 1933, as
amended, or any similar federal statute and the rules and regulations
thereunder, all as the same shall be in effect at the time.

10.2 REQUESTED REGISTRATION.

          (a) If the Company shall receive from the Purchaser a written request
that the Company effect any registration with respect to not less than 33-1/3%
of the issued and outstanding Registrable Securities held by the Purchaser, the
Company shall as soon as practicable use its reasonable best efforts to register
(including, without limitation, the execution of an undertaking to file
post-effective amendments and any other governmental requirements) all
Registrable Securities which the Purchaser requests to be registered; PROVIDED,
that the Company shall not be obligated to file a registration statement
pursuant to this Section 10.2 (i) prior to two years from the Closing Date; (ii)
within 12 months of a prior request under this Section 10.2; (iii) within 120
days following the effective date of any registered offering of the Company's
securities to the general public in which the Purchaser shall have been able
effectively to register all Registrable Securities as to which registration
shall have been requested by the Purchaser; (iv) in any registration having an
aggregate offering price (before deduction of underwriting discounts and
expenses of sale) of less than $7,500,000; or (v) after the Company has effected
three such registrations pursuant to this Section 10.2; PROVIDED, HOWEVER, that
the Company shall be required to effect only one such registration to a
transferee (other than an affiliated entity), after permitted transfer of this
Agreement, pursuant to Section 12.6.

          The Company shall file a registration statement covering the
Registrable Securities so requested to be registered as soon as practical, but
in any event within 90 days after receipt of the request of the Purchaser, and
shall use reasonable best efforts to have such registration statement promptly
declared effective by the Commission whether or not all Registrable Securities
requested to be registered can be included; PROVIDED, HOWEVER, that if the
Company shall furnish


                                  17
<PAGE>


to the Purchaser a certificate signed by the President of the Company stating
that in the good-faith judgment of the Board of Directors it would be
seriously detrimental to the Company and its shareholders for such
registration statement to be filed within such 90-day period and it is
therefore essential to defer the filing of such registration statement, the
Company shall have an additional period of not more than 90 days after the
expiration of the initial 90-day period within which to file such
registration statement; PROVIDED, that during such time the Company may not
file a registration statement for securities to be issued and sold for its
own account.

          (b) If the Purchaser intends to distribute the Registrable Securities
covered by its request by means of an underwriting, it shall so advise the
Company as a part of its request. In that event, if so requested in writing by
the Company, the Purchaser shall negotiate with an underwriter selected by the
Company with regard to the underwriting of such requested registration. The
Company and the Purchaser shall enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting. Notwithstanding any other provision of this Section 10.2, if the
managing underwriter advises the Purchaser in writing that marketing factors
require a limitation of the number of shares to be underwritten, the Company
shall so advise the Purchaser, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
reduced accordingly; PROVIDED, HOWEVER, that securities to be included in such
registration statement as a result of piggyback registration rights as well as
any securities to be offered by the Company shall be excluded from the
registration statement prior to the exclusion of any Registrable Securities held
by the Purchaser.

10.3 PIGGYBACK REGISTRATION.

          (a) If at any time or from time to time the Company shall determine
to register any of its securities, for its own account or the account of any
of its shareholders, other than a registration relating solely to employee
benefit plans, or a registration relating solely to an SEC Rule 145
transaction, a transaction relating solely to the sale of debt or convertible
debt instruments or a registration on any form (other than Form S-1, S-2 or
S-3, or their successor forms) which does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of Registrable Securities, the Company will (i) give to the
Purchaser written notice thereof as soon as practicable prior to filing the
registration statement and (ii) include in such registration and in any
underwriting involved therein all the Registrable Securities (except that
only Shares and Warrant Shares may be included during the two years following
the Closing) specified in a written request, made within 15 days after
receipt of such written notice from the Company by the Purchaser, except as
set forth in subsection 10.3(b).

          (b) If the registration is for a registered public offering
involving an underwriting, the Company shall so advise the Purchaser as a
part of the written notice given pursuant to Section 10.3(a). In such event,
the right of the Purchaser to registration pursuant to this Section 10.3
shall be conditioned upon the Purchaser's participation in such underwriting
and the inclusion of the Purchaser's Registrable Securities in the
underwriting. The Purchaser and the Company shall enter into an underwriting
agreement in customary form with the underwriter or underwriters selected for
such underwriting by the Company. Notwithstanding any other provision of this


                                     18
<PAGE>


Section 10.3, if the managing underwriter determines that marketing factors
require a limitation of the number of shares to be underwritten, the managing
underwriter may limit the number of Registrable Securities to be included in
the registration and underwriting.

10.4 EXPENSES OF REGISTRATION. All expenses incurred in connection with
the registrations pursuant to Sections 10.2 and 10.3, including without
limitation all registration, filing and qualification fees, printing expenses,
fees and disbursements of counsel for the Company and expenses of any special
audits of the Company's financial statements incidental to or required by such
registration, shall be borne by the Company, except that the Company shall not
be required to pay underwriters' fees, discounts or commissions relating to
Registrable Securities or fees of a separate legal counsel of the Purchaser.

10.5 REGISTRATION PROCEDURES. In the case of each registration effected
by the Company pursuant to this Agreement, the Company will keep the Purchaser
advised in writing as to the initiation of each registration and as to the
completion thereof. At its expense the Company will:

     (a) keep such registration pursuant to Sections 10.2 and 10.3
continuously effective for a period of 120 days, or, in each case, such
reasonable period necessary to permit the Purchaser to complete the distribution
described in the registration statement relating thereto, whichever first
occurs;

     (b) promptly prepare and file with the Commission such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to comply with the provisions
of the Securities Act, and to keep such registration statement effective for
that period of time specified in Section 10.5(a);

     (c) furnish such number of prospectuses and other documents
incident thereto as the Purchaser from time to time may reasonably request;

     (d) use reasonable best efforts to obtain the withdrawal of
any order suspending the effectiveness of a registration statement, or the
lifting of any suspension of the qualification of any of the Registrable
Securities for sale in any jurisdiction, at the earliest possible moment;

     (e) register or qualify such Registrable Securities for offer and sale
under the securities or Blue Sky laws of such jurisdictions as the Purchaser
or underwriter reasonably requires (except that the Company shall not be
required to go register or qualify in any jurisdiction in which it would be
required to execute a general consent to service of process), and keep such
registration or qualification effective during the period set forth in
Section 10.5(a);

     (f) cause all Registrable Securities covered by such registrations to be
listed on each securities exchange, including NASDAQ, on which similar
securities issued by the Company are then listed;

     (g) cause its accountants to issue to the underwriter, if any, comfort
letters and updates thereof, in customary form and covering matters of the
type customarily covered in such letters with respect to underwritten
offerings;

                                   19
<PAGE>


     (h) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the
Purchaser reasonably requests in order to expedite or facilitate the
disposition of such Registrable Securities;

     (i) make available for inspection by Purchaser, 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 seller, underwriter, attorney, accountant or agent in
connection with such registration statement;

     (j) if the offering is underwritten, at the request of the Purchaser
furnish (i) an opinion of counsel representing the Company for the purposes
of such registration, addressed to the underwriters, stating that such
registration statement has become effective under the Securities Act and that
(A) to the best knowledge of such counsel, no stop order suspending the
effectiveness thereof has been issued and no proceedings for that purpose
have been instituted or are pending or contemplated under the Securities Act,
(B) the registration statement, the related prospectus and each amendment or
supplement thereof comply as to form in all material respects with the
requirements of the Securities Act (except that such counsel need not express
any opinion as to financial statements or other financial data contained
therein) and (C) to such other effects as reasonably may be requested by
counsel for the underwriters and (ii) a letter from the independent public
accountants retained by the Company, addressed to the underwriters and to
such seller, stating that they are independent public accountants within the
meaning of the Securities Act and that, in the opinion of such accountants,
the financial statements of the Company included in the registration
statement or the prospectus, or any amendment or supplement thereof, comply
as to form in all material respects with the applicable accounting
requirements of the Securities Act, and such letter shall additionally cover
such other financial matters (including information as to the period ending
no more than five business days prior to the date of such letter) with
respect to such registration as such underwriters reasonably may request; and

     (k) notify the Purchaser at any time a prospectus covered by such
registration statement is required to be delivered under the Securities Act,
of the happening of any event of which it has knowledge 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.

Notwithstanding any other provision of this Section 10, (i) the Company shall
not be required to file a registration statement during any period that such
filing is not permitted and (ii) the Purchaser shall suspend any sale of
Registrable Securities at the request of the Company for a period not exceeding
90 days.

<PAGE>


     (a) In the event of a registration of any of the Registrable
Securities under the Securities Act pursuant to Sections 10.2 or 10.3, the
Company will indemnify and hold harmless the Purchaser, each underwriter of such
Registrable Securities thereunder and each other person, if any, who controls
the Purchaser or underwriter within the meaning of the Securities Act, against
any losses, claims, damages or liabilities, joint or several, to which the
Purchaser, underwriter or controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such Registrable Securities were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein, or any amendment or supplement thereof, or arise
out of or are based upon 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 any violation by the Company of any rule or
regulation promulgated under the Securities Act or any state securities law
applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration, and will reimburse the
Purchaser, each of its officers, directors and partners, and each person
controlling the Purchaser, each such underwriter and each person who controls
any such underwriter, for any reasonable legal and any other expenses incurred
in connection with investigating, defending or settling any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage or liability arises
out of or is based on any untrue statement or omission based upon written
information furnished to the Company by an instrument duly executed by the
Purchaser or underwriter specifically for use therein.

     (b) The Purchaser will indemnify and hold harmless the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company and each underwriter within the meaning of the Securities Act,
against all claims, losses, expenses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission
(or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse the Company, such directors, officers, partners, persons or
underwriters for any reasonable legal or any other expenses incurred in
connection with investigating, defending or settling any such claim, loss,
damage, liability or action, in each case to the extent, but only to the
extent, that such untrue statement (or alleged untrue statement) or omission
(or alleged omission) is made in such registration statement, prospectus,
offering circular or other document in reliance upon and in conformity with
written information furnished to the Company by an instrument duly executed
by the Purchaser specifically for use therein; PROVIDED, HOWEVER, the total
amount for which the Purchaser, its officers, directors and partners, and any
person controlling the Purchaser, shall be liable under this Section 10.6(b)
shall not in any event exceed the aggregate proceeds received by the
Purchaser from the sale of Registrable Securities in such registration.

     (c) Each party entitled to indemnification under this Section 10.6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified
Party has actual knowledge of any claims as to which indemnity may be sought,
and shall permit the Indemnifying Party to assume the defense of any such
claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall
not be unreasonably withheld), and the Indemnified Party may participate in
such defense at such party's expense, and provided further that the failure
of any Indemnified Party to give notice as provided herein shall not relieve
the Indemnifying Party of its obligations hereunder, unless such failure
resulted in actual detriment to the Indemnifying Party. No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof
the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect of such claim or litigation.

     (d) Notwithstanding the foregoing, to the extent that the provisions on
indemnification contained in the underwriting agreement entered into among
the Purchaser, the Company and the underwriters in connection with the
underwritten public offering are in conflict with the foregoing provisions,
the provisions in the underwriting agreement shall be controlling as to the
Registrable Securities included in the public offering.

     (e) If the indemnification provided for in this Section 10.6 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 thereunder, 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 hand in connection with the statements or omissions which resulted in
such loss, liability, claim, damage or expense as well as any other relevant
equitable considerations. The relevant fault of the indemnifying party and
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. Notwithstanding the foregoing, the amount
the Purchaser shall be obligated to contribute pursuant to this Section
10.6(e) shall be limited to an amount equal to the proceeds to the Purchaser
of the Restricted Securities sold pursuant to the registration statement
which gives rise to such obligation to contribute (less the aggregate amount
of any damages which the Purchaser has otherwise been required to pay in
respect of such loss, claim, damage, liability or action or any substantially
similar loss, claim, damage, liability or action arising from the sale of
such Restricted Securities).

     (f) The indemnification provided by this Section 10.6 shall be a
continuing right to indemnification and shall survive the registration and
sale of any securities by any Person entitled to indemnification hereunder
and the expiration or termination of this Agreement.

                                      22

10.7 LOCKUP AGREEMENT. The Purchaser agrees in connection with any
registration of the Company's securities (whether or not the Purchaser is
participating in such registration), upon the request of the Company and the
underwriters managing any underwritten offering of the Company's securities,
not to sell, make any short sale of, loan, grant any option for the purchase
of, or otherwise dispose of any Registrable Securities (other than those

underwriters may reasonably specify.

10.8 INFORMATION BY THE PURCHASER. The Purchaser included in any registration
shall promptly furnish to the Company such information regarding the
Purchaser and the distribution proposed by the Purchaser as the Company may
request in writing and as shall be required in connection with any
registration referred to herein.

10.9     TERMINATION OF RIGHTS.

     (a) The rights of the Purchaser to cause the Company to register

Purchaser is able to dispose of all of its Registrable Securities in one
three-month period pursuant to the provisions of Rule 144.

     (b) Notwithstanding the provisions of Section 10.9(a), all rights of the
Purchaser under this Agreement shall terminate at 5:00 P.M. Central time on

                            DIAMETRICS MEDICAL, INC.

                             STOCK PURCHASE WARRANT

THE WARRANTS EVIDENCED HEREBY AND THE SHARES OF STOCK ISSUABLE UPON EXERCISE
THEREOF HAVE NOT BEEN REGISTERED UNDER SECURITIES ACT OF 1933, AS AMENDED, AND
MAY NOT BE OFFERED OR SOLD WITHOUT REGISTRATION UNLESS AN EXEMPTION FROM
REGISTRATION IS AVAILABLE UNDER SUCH ACT OR THE RULES OR REGULATIONS PROMULGATED
THEREUNDER.

                                                                  June 28, 1999

                                     WARRANT

     To Subscribe for and Purchase Common Stock of Diametrics Medical, Inc.

     VOID AFTER 5:00 P.M., MINNEAPOLIS, MINNESOTA TIME, ON AUGUST 4, 2003,
OR IF NOT A BUSINESS DAY, AS DEFINED HEREIN, AT 5:00 P.M., MINNEAPOLIS TIME, ON
                    THE IMMEDIATELY PRECEDING BUSINESS DAY

This certifies that, for valuable consideration, receipt of which is hereby
acknowledged, Hewlett-Packard Company, and permitted successors and assigns
("Holder") is entitled to purchase from Diametrics Medical, Inc. a Minnesota
corporation (the "Company") up to and including 452,381 fully paid and
nonassessable shares (the "Number of Shares") of the common stock of the
Company, $.01 par value (the "Common Stock"), on the terms set forth herein
at an exercise price per share equal to $8.40 (the "Purchase Price"). The
Number of Shares and the Purchase Price may be adjusted from time to time as
described in this Warrant.

1.       EXERCISE.

1.1      TIME FOR EXERCISE. This Warrant may be exercised in whole or in part
at any time, and from time to time, during the period commencing on the date
of this Warrant and expiring on August 4, 2003.

1.2      MANNER OF EXERCISE. This Warrant shall be exercised by delivering it
to the Company with the exercise form duly completed and signed, specifying
the number of shares as to which the Warrant is being exercised at that time
(the "Exercise Number"). The Holder shall simultaneously deliver to the
Company cash or a certified check or wire transfer in an amount equal to the
Exercise Number multiplied by the Purchase Price, and the Holder shall be
entitled to receive the full Exercise Number of shares of Common Stock.

1.3      EFFECTIVE DATE OF EXERCISE. Promptly (but in any case within ten
business days) after any exercise, the Company shall deliver to the Holder
(a) duly executed certificates in the name or


<PAGE>

names specified in the exercise notice representing the aggregate number of
shares issuable upon such exercise, and (b) if this Warrant is exercised only
in part, a new Warrant of like tenor exercisable for the balance of the
Number of Shares. Such certificates shall be deemed to have been issued, and
the person receiving them shall be deemed to be a holder of record of such
shares, as of the close of business on the date the  actions required in
Section 1.2 shall have been completed or, if on that date   the stock
transfer books of the Company are closed, as of the next business day.

2.       TRANSFER OF WARRANTS AND STOCK.

2.1      TRANSFER RESTRICTIONS. This Warrant shall be freely transferable by
the Holder in accordance with the terms hereof; provided, however, that
neither this Warrant nor the securities issuable upon its exercise may be
sold, transferred or pledged unless the Company shall have been supplied with
reasonably satisfactory evidence that such transfer is not in violation of
the Securities Act of 1933, as amended (the "Securities Act"), and any
applicable state securities laws. The Company may place a legend to that
effect on this Warrant, any replacement Warrant and each certificate
representing shares issuable upon exercise of this Warrant. Subject to the
satisfaction of this condition only, this Warrant shall be freely
transferable by the Holder.

2.2      MANNER OF TRANSFER. Upon delivery of this Warrant to the Company
with the assignment form duly completed and signed, the Company will promptly
(but in any case within five (5) business days) execute and deliver to each
transferee and, if applicable, the Holder, Warrants of like tenor evidencing
the rights (a) of the transferee(s) to purchase the Number of Shares
specified for each in the assignment forms, and (b) of the Holder to purchase
any untransferred portion, which in the aggregate shall equal the number of
Shares of the original Warrant. If this Warrant is properly assigned in
compliance with Section 2, it may be exercised by an assignee without having
a new Warrant issued.

2.3      LOSS, DESTRUCTION OF WARRANT CERTIFICATES. Upon receipt of (a)
evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of any Warrant and (b) except in the case of
mutilation, an indemnity or security reasonably satisfactory to the Company,
the Company will promptly (but in any case within five (5) business days)
execute and deliver a replacement Warrant of like tenor representing the
right to purchase the same Number of Shares.

3.       COST OF ISSUANCES. The Company shall pay all expenses, transfer
taxes and other charges payable in connection with the preparation, issuance
and delivery of stock certificates or replacement Warrants, except for any
transfer tax or other charge imposed as a result of (a) any issuance of
certificates in any name other than the name of the Holder, or (b) any
transfer of the Warrant. The Company shall not be required to issue or
deliver any Stock certificate or Warrant until it receives reasonably
satisfactory evidence that any such tax or other charge has been paid by the
Holder.

4.       ANTI-DILUTION PROVISIONS. If any of the following events occur at
any time hereafter during the life of this Warrant, then the Purchase Price
and the Number of Shares immediately prior to such event shall be changed as
described in order to prevent dilution:

                                     2
<PAGE>


4.1      DIVIDENDS; STOCK SPLITS ETC. In case the Company shall (a) pay a
dividend in shares of Common Stock or make a distribution in shares of Common
Stock, (b) subdivide or reclassify its outstanding shares of Common Stock
into a greater number of shares, or (c) combine or reclassify its outstanding
shares of Common Stock into a smaller number of shares, the Number of Shares
purchasable upon the exercise of this Warrant immediately prior thereto shall
be adjusted so that the Number of Shares purchasable upon exercise of this
Warrant shall be determined by multiplying the Number of Shares theretofore
purchasable upon the exercise of this Warrant by a fraction, of which the
numerator shall be the number of shares of Common Stock outstanding
immediately following such action and of which the denominator shall be the
number of shares of Common Stock outstanding immediately prior thereto. Such
adjustment shall be made whenever any event listed above shall occur and
shall become effective immediately after the record date in the case of a
dividend and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification. If the Company
declares a dividend in money on its Common Stock and at substantially the
same time offers its Stockholders a right to purchase new shares of Common
Stock or of capital stock of any other class from the proceeds of such
dividend, or for an amount substantially equal to such dividend, all shares
of Common Stock or of capital stock of any other class so issued shall for
purposes hereof be deemed issued as a Stock dividend.

4.2      ISSUANCE OF RIGHTS OR WARRANTS TO HOLDERS. In case the Company shall
issue rights, options or warrants to all holders of its shares of Common
Stock entitling them (for a period expiring within 45 days after the record
date therefor) to subscribe for or purchase shares of Common Stock at a price
per share which is lower at the record date mentioned below than the then
Current Market Price per share of Common Stock (as hereinafter defined), the
Number of Shares thereafter purchasable upon the exercise of this Warrant
shall be determined by multiplying the Number of Shares theretofore
purchasable upon exercise of this Warrant by a fraction, of which the
numerator shall be the number of shares of Common Stock outstanding on such
record date plus the number of additional shares of Common Stock offered for
subscription or purchase, and of which the denominator shall be the number of
shares of Common Stock outstanding on such record date plus the number of
shares which the aggregate offering price of the total number shares of
Common Stock so offered would purchase at the then Current Market Price per
share of Common Stock. For purposes of this Section 4.2, the issuance of
rights, options or warrants to subscribe for or purchase securities
convertible into Common Stock shall be deemed to be the issuance of rights,
options or warrants to purchase the Common Stock into which such securities
are convertible at an aggregate offering price equal to the aggregate
offering price of such securities plus the minimum aggregate amount (if any)
payable upon conversion of such securities into Common Stock.

4.3      MERGER; CONSOLIDATION; SALE OF ASSETS. In case of (a) the
consolidation or the merger of the Company, (b) the sale of all or
substantially all of the properties and assets of the Company to any Person,
(c) any capital reorganization by the Company, or (d) any voluntary or
involuntary dissolution, liquidation, or winding up of the Company, this
Warrant shall, after any such event, entitle the Holder to receive upon
exercise the number of shares of Stock or other securities or property
(including cash) of the Person (if applicable) resulting from such event,
which the holder of securities deliverable upon exercise of this Warrant (at
the time of such

                                     3
<PAGE>

event) would have been entitled to receive upon such event; and in any such
case the provisions of Section 4 with  respect to the rights and interests
thereafter of the holders of this Warrant   shall be appropriately adjusted
so as to be applicable, as nearly as practicable, to any shares of Stock or
other securities or any property (including cash) thereafter deliverable upon
exercise of this Warrant. The Person resulting from such sale or
consolidation or surviving such merger or to which such sale shall be made
shall execute and deliver to the Holder a supplemental agreement as provided
in Section 6.5 below. Any adjustment pursuant to this Section 4.3 which shall
be approved in good faith by the Board of Directors of the Company pursuant
to a resolution delivered to the Holder shall be conclusive for all purposes
hereof. For the purposes of this Agreement "person" means any individual,
partnership, firm, corporation, limited liability company or partnership,
association, trust, unincorporated organization or other entity, as well as
any syndicate or group that would be deemed to be a person under Section
13(d)(3) of the Securities Exchange Act of 1934, as amended.

4.4      OTHER DISTRIBUTIONS. In case the Company shall distribute to all
holders of its shares of Common Stock shares of Stock other than Common Stock
or evidences of its indebtedness or assets (excluding cash dividends or
distributions payable out of consolidated earnings or retained earnings and
dividends or distributions referred to in Section 4.1 above) or rights,
options, warrants or convertible or exchangeable securities containing the
right to subscribe for or purchase shares of Common Stock (excluding those
referred to in Section 4.2 above), then in each case the Number of Shares
thereafter purchasable upon the exercise of this Warrant shall be determined
by multiplying the Number of Shares theretofore purchasable upon the exercise
of this Warrant, by a fraction of which the numerator shall be the Current
Market Price per share of Common Stock on the record date mentioned below in
this Section 4.4 plus the then fair value (as reasonably determined by the
Board of Directors of the Company in good faith, whose determination shall be
conclusive absent manifest error, irrespective of the accounting treatment
thereof) of the portion of the shares of Stock other than Common Stock or
assets or evidences of indebtedness so distributed or of such subscription
rights, options or warrants, or of such convertible or exchangeable
securities applicable to one share of Common Stock, and of which the
denominator shall be the Current Market Price per share of Common Stock on
such record date. Such adjustment shall be made whenever any such
distribution is made, and shall become effective immediately after the record
date for the determination of Stockholders entitled to receive such
distribution.

4.5      ADDITIONAL ADJUSTMENT OF PURCHASE PRICE. Whenever the Number of
Shares purchasable upon the exercise of this Warrant is adjusted, as provided
herein, the Purchase Price payable upon exercise of this Warrant shall be
adjusted by multiplying such Purchase Price immediately prior to such
adjustment by a fraction, of which the numerator shall be the Number of
Shares purchasable upon the exercise of this Warrant immediately prior to
such adjustment, and of which the denominator shall be the Number of Shares
so purchasable immediately thereafter.

4.6      NO DE MINIMIS ADJUSTMENTS. No adjustment in the Purchase Price shall
be required unless such adjustment would require an increase or decrease of
at least 1% in such price; provided, however, that any adjustments which by
reason of this Section 4.6 are not required to be made shall be carried
forward and taken into account in any subsequent adjustment. All

                                     4
<PAGE>


calculations under this Section 4.6 shall be made to the nearest
one-twentieth of a cent or to the nearest one-hundredth of a share, as the
case may be.

4.7      TREASURY SHARES. For the purpose of Section 4, shares of Common
Stock or other securities held in the treasury of the Company shall not be
deemed to be outstanding, and the sale or other deposition of any shares of
Common Stock or other securities held in the treasury of the Company shall be
deemed an issuance thereof.

4.8      CORPORATE ACTION. Before taking any action which would cause an
adjustment reducing the Purchase Price below the then par value, if any, of
the shares of Common Stock issuable upon exercise of this Warrant, the
Company shall take any corporate action which may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock at such adjusted Purchase
Price.

4.9      INDEPENDENT PUBLIC ACCOUNTANTS. The certificate of a "Big Five" firm
of independent public accountants selected by the Board of Directors of the
Company shall be conclusive evidence of the correctness of any computation
made under Section 4.

4.10     NOTICE OF CERTAIN EVENTS. In case at any time prior to the
expiration date of this Warrant:

                  (i) the Company shall declare a dividend (or any other
         distribution) on the Common Stock (other than a dividend in cash out of
         retained earnings); or

                  (ii) the Company shall authorize the granting to the holders
         of Common Stock of rights or warrants to subscribe for or purchase any
         shares of stock of any class or of any other rights; or

                  (iii) there shall be any reclassification of the Common Stock
         of the Company (other than a subdivision or combination of its
         outstanding Common Stock); or

                  (iv) there shall be any capital reorganization by the
         Company; or

                  (v) there shall be a consolidation or merger involving the
         Company or sale of all or substantially all of the Company's property
         and assets (except a merger or other reorganization in which the
         Company shall be the surviving corporation or a consolidation, merger
         or sale with a wholly-owned subsidiary); or

                  (vi) there shall be voluntary or involuntary dissolution,
         liquidation and winding up by the Company or dividend or distribution
         to holders of Common Stock (other than the customary cash and stock
         dividends); or

                  (vii) any other action shall occur which would give rise to an
         adjustment to the Purchase Price or the Number of Shares hereunder,
         then in any one or more of said cases, the Company shall cause to be
         delivered to the Holder, at the earliest practicable time (and, in any
         event, not less than 25 days before any record date or other date set
         for definitive action), notice of the date on which the books of the
         Company shall close or a

                                     5
<PAGE>


         record shall be taken for such dividend, distribution or subscription
         rights or such reorganization, sale, consolidation, merger,
         dissolution, liquidation or winding up shall take place, as the case
         may be. Such notice shall also set forth such facts as shall indicate
         the effect of such action (to the extent such effect may be known at
         the date of such notice) on the Purchase Price and the kind and amount
         of the shares of stock and other securities and property deliverable
         upon exercise of this Warrant. Such notice shall also specify the date,
         if known, as of which the holders of record of the Common Stock shall
         participate in said dividend, distribution or subscription rights or
         shall be entitled to exchange their shares of the Common Stock for
         securities or other property (including cash) deliverable upon such
         reorganization, sale, consolidation, merger, dissolution, liquidation
         or winding up, as the case may be (on which date, in the event of
         voluntary or involuntary dissolution, liquidation, or winding up of
         the Company, other than dissolution, liquidation or winding up
         following a consolidation or merger of the Company with or into, or
         sale of substantially all of its assets to, another corporation, the
         rights to exercise this Warrant shall terminate).

4.11     OTHER SECURITIES ADJUSTMENTS. If as a result of Section 4, a Holder
is entitled to receive any securities other than Common Stock upon exercise
of this Warrant, the number and purchase price of such securities shall
thereafter be adjusted from time to time in the same manner as provided
pursuant to Section 4 for Common Stock. The allocation of purchase price
between various securities shall be made in writing by the Board of Directors
of the Company in good faith at the time of the event by which the holder
became entitled to receive new securities, and a copy sent to the Holder.

4.12     NOTICES OF ADJUSTMENTS. When any adjustment is required to be made
under Section 4, the Company shall promptly (a) determine such adjustments,
(b) prepare and retain on file a statement describing in reasonable detail
the method used in arriving at the adjustment; and (c) cause a copy of such
statement, together with any agreement required by Section 6.5, to be mailed
to the Holder within 10 days after the date on which the circumstances giving
rise to such adjustment occurred.

4.13     COMPUTATIONS AND ADJUSTMENTS. Upon each computation of an adjustment
under this Section 4, the Purchase Price shall be computed to the nearest
cent and the Number of Shares shall be calculated to the next highest whole
share. However, the fractional amount shall be used in calculating any future
adjustments. No fractional shares of Common Stock shall be issued in
connection with the exercise of this Warrant, but the Company shall, in the
case of the final exercise under this Warrant, make a cash payment for any
fractional shares based on the Current Market Price of the Common Stock on
the date of exercise. Notwithstanding any changes in the Purchase Price or
the Number of Shares, this Warrant, and any Warrants issued in replacement or
upon transfer thereof, may continue to state the initial Purchase Price and
the Number of Shares. Alternatively, the Company may elect to issue a new
Warrant or Warrants of like tenor for the additional shares of Common Stock
purchasable hereunder or, upon surrender of the existing Warrant, to issue a
replacement Warrant evidencing all the Warrants to which the Holder is
entitled after such adjustments.

                                     6
<PAGE>

4.14     EXERCISE BEFORE PAYMENT DATE. In the event that this Warrant is
exercised after the record date for any event requiring an adjustment, but
prior to the actual event, the Company may elect to defer payment of the
adjusted amount to the Holder until the actual event occurs; provided,
however, that the Company shall deliver a due bill or other appropriate
instrument to the Holder transferable to the same extent as the other
securities issuable on exercise evidencing the Holder's right to receive such
additional amount upon the occurrence of the event requiring such adjustment.

4.15     CURRENT MARKET PRICE. "Current Market Price" for the Common Stock on
any given date means (a) the closing price on the previous trading day for
the Common Stock on the principal stock exchange on which the Common Stock is
traded (or, in the case of issuances of stock options with an exercise price
equal to fair market value on the date of grant pursuant to the terms of a
plan, such date) or (b) if not so traded, the closing price (or, if no
closing price is available, the average of the bid and asked prices) for such
date on the NASDAQ if the Common Stock is listed on the NASDAQ or (c) if not
listed on any exchange or quoted on the NASDAQ, such value as may be
determined in good faith by the Company's Board of Directors, which
determination shall be conclusively binding on the parties.

5.       REDEMPTION.

5.1      REDEMPTION AT COMPANY'S OPTION. The Company may, upon 30 days prior
written notice (the "Redemption Notice") to the Holder, redeem all, but not
less than all of the Warrants granted hereunder that have not been exercised
before the date referred to in Section 5.2(d) at a redemption price of $0.05
per Warrant (the "Redemption Price"), so long as the Current Market Price (as
defined in Section 4.15(a) and (b) above) is greater than the following
prices (the "Target Prices") for any period of 20 consecutive trading days
preceding the date the Redemption Notice is given:

<TABLE>

          August 5, 2000-- August 4, 2001                          $14.52

          August 5, 2001-- August 4, 2002                          $17.42

          August 5, 2002-- August 4, 2003                          $20.90
</TABLE>

          The date fixed for redemption of this Warrant is referred to herein as
the "Redemption Date."

5.2      REDEMPTION NOTICE. The Redemption Notice shall specify (a) the
Redemption Price, (b) the Redemption Date, (c) the place where this Warrant
shall be delivered and the Redemption Price paid, and (d) that the right to
exercise the Warrant shall terminate at 5:00 p.m. (Minneapolis time) on the
business day immediately preceding the Redemption Date. No failure to mail
such notice nor any defect therein or in the mailing thereof shall affect the
validity of the proceedings for such redemption except as to a Holder (I) to
whom notice was not mailed (ii) whose notice was defective.

                                     7
<PAGE>

5.3      FAILURE TO EXERCISE. Any right to exercise this Warrant shall
terminate at 5:00 p.m. (Minneapolis time) on the business day immediately
preceding the Redemption Date. On and after the Redemption Date, the Holder
shall have no further rights except to receive, upon surrender of this
Warrant, the Redemption Price.

5.4      SURRENDER OF WARRANT. From and after the Redemption Date, the
Company shall, at the place specified in the Redemption Notice, upon
presentation and surrender to the Company by or on behalf of the Holder of
the Warrant to be redeemed, deliver or cause to be delivered to or upon the
written order of the Holder a sum in cash equal to the Redemption Price of
this Warrant. From and after the Redemption Date and upon the deposit or
setting aside by the Company of a sum sufficient to redeem this Warrant, it
shall expire and become void and all rights hereunder, except the right to
receive payment of the Redemption Price, shall cease.

5.5      ADJUSTMENTS. If the shares of Common Stock are subdivided or
combined into a greater or smaller number of shares of Common Stock, the
Target Prices shall be proportionally adjusted by the ratio which the total
number of shares of Common Stock outstanding immediately prior to such event
bears to the total number of shares of Common Stock to be outstanding
immediately after such event.

6.       COVENANTS. The Company agrees that:

6.1      RESERVATION OF STOCK. During the period in which this Warrant may be
exercised, the Company will reserve sufficient authorized but unissued
securities to enable it to satisfy its obligations on exercise of this
Warrant and shall use its reasonable best efforts to cause all shares of
Common Stock issued upon the exercise of this Warrant to be listed on any
exchanges on which the Common Stock is then listed. If at any time the
Company's authorized securities shall not be sufficient to allow the exercise
of this Warrant, the Company shall take such corporate action as may be
necessary to increase its authorized but unissued securities to be sufficient
for such purpose;

6.2      NO LIENS, ETC. All securities that may be issued upon exercise of
this Warrant will, upon issuance, be validly issued, fully paid,
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, and shall be listed on any exchanges on which that class of
securities is listed;

6.3      FURNISH INFORMATION. During the term of this Warrant, the Company
will promptly deliver to the Holder copies of all financial statements,
reports and proxy statements which the Company shall have sent to its
stockholders generally;

6.4      STOCK AND WARRANT TRANSFER BOOKS. Except upon dissolution,
liquidation or winding up or for ordinary holidays and weekends, the Company
will not at any time close its stock or warrant transfer books so as to
result in preventing or delaying the exercise or transfer of this Warrant; and

                                     8
<PAGE>

6.5      MERGER; CONSOLIDATION OR SALE OF ASSETS OF THE COMPANY. Except in
the case of a merger or consolidation where the consideration is payable
entirely in cash or obligations, the Company will not merge or consolidate
with or into any Person, or sell or otherwise transfer its property, assets
and business substantially as an entirety to a successor Person, unless the
Person resulting from such merger or consolidation (if not the Company), or
such successor Person, shall expressly assume, by supplemental agreement
reasonably satisfactory in form to the then Majority Holders (as defined
below) and executed and delivered to the Holder, the due and punctual
performance and observance of each and every covenant and condition of this
Agreement to be performed and observed by the Company. "Majority Holders", as
of any date, shall mean the holders of this Warrant (or replacement warrants
issued pursuant hereto) and of the substantially similar warrants issued
contemporaneously herewith pursuant to the Common Stock Purchase Agreement
(or replacement warrants issued pursuant thereto) who together have rights to
exercise such warrants for a majority of the Warrant Shares (as defined in
the Common Stock Purchase Agreement).

7.       STATUS OF HOLDER.

7.1      NOT A STOCKHOLDER. Unless the Holder exercises this Warrant in
writing, the Holder shall not be entitled to any rights (a) as a stockholder
of the Company with respect to the shares as to which the Warrant is
exercisable including, without limitation, the right to vote or receive
dividends or other distributions, or (b) to receive any notice of any
proceedings of the Company except as otherwise provided in this Warrant.

7.2      LIMITATION OF LIABILITY. Unless the Holder exercises this Warrant in
writing, the Holder's rights and privileges hereunder shall not give rise to
any liability for the Purchase Price or as a stockholder of the Company,
whether to the Company or its creditors.

8.       REGISTRATION RIGHTS. The shares purchasable upon exercisable of this
Warrant shall be Registerable Securities as defined in Section 10.1 of the
Common Stock Purchase Agreement.

9.       GENERAL PROVISIONS.

9.1      COMPLETE AGREEMENT; Modifications. This Warrant and any documents
referred to herein or executed contemporaneously herewith constitute the

         Re:    Diametrics Medical, Inc.

Dear Sirs:

Reference is made to the Common Stock Purchase Agreement between Diametrics
Medical, Inc. and Hewlett-Packard Company to be entered into on the date
hereof substantially in the form attached hereto as Exhibit A (the "Purchase
Agreement"). All capitalized terms used but not otherwise defined in this
letter shall have the meanings ascribed to them in the Purchase Agreement.

Based on our review of Company's recent SEC filings, we understand that you
have a significant ownership position in Company. The Purchaser is unwilling
to enter into the Purchase Agreement absent your assurance regarding certain
matters addressed in Section 9.9 of the Purchase Agreement. In order to
further induce the Purchaser to enter into the Purchase Agreement and to
consummate the transactions contemplated thereby, the Purchaser hereby
requests that you agree as follows:

1. Upon the written request of the Purchaser, following the closing
contemplated under the Purchase Agreement, you will promptly enter into an
agreement with the Purchaser in accordance with the terms of Section 9.9 of
the Purchase Agreement. Such agreements will be suspended at such times, if
any, during the Two-Year Period that the Purchaser's owned voting power in
Company falls below (a) 12% due to transfers of Company equity by the
Purchaser and/or (b) 10% for any other reason. Such agreement shall only be
effective during the Two-Year Period.

2. You believe that, as a shareholder of Company, you will derive substantial
indirect benefit from the Purchaser's execution, delivery and performance of
the Purchase Agreement and the consummation of the transactions contemplated
thereby.

      Re:         Diametrics Medical, Inc.

Dear Mr. Craves:

Reference is made to the Common Stock Purchase Agreement between Diametrics
Medical, Inc. and Hewlett-Packard Company to be entered into on the date
hereof substantially in the form attached hereto as Exhibit A (the "Purchase
Agreement"). All capitalized terms used but not otherwise defined in this
letter shall have the meanings ascribed to them in the Purchase Agreement.

Based on our review of Company's recent SEC filings, we understand that you
have a significant ownership position in Company. The Purchaser is unwilling
to enter into the Purchase Agreement absent your assurance regarding certain
matters addressed in Section 9.9 of the Purchase Agreement. In order to
further induce the Purchaser to enter into the Purchase Agreement and to
consummate the transactions contemplated thereby, the Purchaser hereby
requests that you agree as follows:

1. Upon the written request of the Purchaser, following the closing
contemplated under the Purchase Agreement, you will promptly enter into an
agreement with the Purchaser in accordance with the terms of Section 9.9 of
the Purchase Agreement. Such agreements will be suspended at such times, if
any, during the Two-Year Period that the Purchaser's owned voting power in
Company falls below (a) 12% due to transfers of Company equity by the
Purchaser and/or (b) 10% for any other reason. Such agreement shall only be
effective during the Two-Year Period.

2. You believe that, as a shareholder of Company, you will derive substantial
indirect benefit from the Purchaser's execution, delivery and performance of
the Purchase Agreement and the consummation of the transactions contemplated
thereby.

Please execute a copy of this letter in the space indicated to confirm your
agreement with the matters set forth in clauses (1) and (2) above, and
forward the signed letter by facsimile to the attention of Ross Katchman at
650/857-4837, with hard copy to follow by U.S. Mail.

Thank you for your cooperation in this matter.


                               Sincerely,

                               HEWLETT-PACKARD COMPANY
