ITEM 1.  CHANGE IN CONTROL OF REGISTRANT.

         On November 14, 1997, LifeRate Systems, Inc. (the "Company") entered
into a Securities Purchase Agreement (the "Purchase Agreement") with Special
Situations Private Equity Fund, L.P., Special Situations Cayman Fund, L.P.,
Special Situations Fund III, L.P. (collectively, the "Funds") and the other
purchasers named in the Purchase Agreement (the Funds and such other purchasers
are collectively referred to herein as the "Purchasers"), pursuant to which the
Company agreed to sell for cash up to 9,000,000 shares (the "Shares") of common
stock, no par value (the "Common Stock") of the Company at prices ranging from
$.50 to $.56 per share and warrants (the "Warrants") to purchase up to 9,000,000
shares of Common Stock, as well as an additional 104,000 Shares and Warrants for
cancellation of certain indebtedness (the "Financing"). The Warrants are
exercisable for a period of 10 years at a price of $1.50 per share, subject to
adjustment as provided in the Warrants. The first closing under the Purchase
Agreement was held on November 14, 1997, at which the Company sold an aggregate
of 2,500,000 Shares at a price of $.50 per share and issued an aggregate of
2,500,000 Warrants to the Funds for an aggregate purchase price of $1,250,000
and an aggregate of 104,000 Shares and Warrant for the cancellation of $52,000
of indebtedness (the "First Closing"). The interim closing called for under the
Purchase Agreement was held on November 21, 1997, at which the Company sold an
additional 1,790,000 Shares at a price of $.56 per share and issued an
additional 1,790,000 Warrants to purchasers other than the Funds for an
aggregate purchase price of $1,002,400. The Shares and Warrants acquired by the
Funds in these transactions constitute "beneficial ownership" (within the
meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of
45.6% of the Company's Common Stock as of November 21, 1997.

         The Shares and Warrants were offered pursuant to the Selling Agency
Agreement (the "Selling Agency Agreement") dated as of September 2, 1997, and as
amended as of November 14, 1997, by and between the Company and Miller Johnson &
Kuehn Incorporated ("MJK"). The Selling Agency Agreement provides that MJK is to
receive a commission of 10% of the purchase price of the Shares sold to
Purchasers other than the Funds and is to receive a non-accountable expense
allowance equal to 1% of the purchase price of Shares on which it is paid a
commission. Accordingly, the Company paid MJK commissions of $100,240 and a
non-accountable expense allowance of $10,024 with respect to the 1,790,000
Shares and Warrants sold at the interim closing. In addition, the Company paid
the fees of counsel to MJK, as well as the Funds.

         The Purchase Agreement also provides that, in the event the Company
fulfills certain conditions by January 15, 1998 (the "Second Closing
Conditions"), the Company will sell to the Funds and other Purchasers an
additional 4,500,000 Shares and Warrants to purchase 4,500,000 shares of Common
Stock at a purchase price of between $.50 and $.56 per share on or before
January 31, 1998 (the "Second Closing"). The Second Closing Conditions include
(a) the approval by the shareholders of the Company of an amendment to the
Company's Articles of Incorporation to increase the total number of authorized
shares of Common Stock to an aggregate of 75,000,000 and (b) the attainment by
the Company no later than January 15, 1998, of the following milestones: (i) the
Company's revenues derived from the sale of existing or new

<PAGE>


systems during the period from October 1, 1997, through January 15, 1998, shall
be at least $200,000; (ii) the Company shall have executed letters of intent
and/or sales contracts, each with a minimum value of $5,000, with at least five
new (excluding current or previous) customers for the sale of any existing or
new systems during the period from October 1, 1997 through January 15, 1998; and
(iii) the Company shall have made generally available for sale a commercially
marketable entry level cardiac cath lab product designed to support the data
requirements of the American College of Cardiology, with a sales price range of
$5,000-$15,000. If the Second Closing Conditions are met, the Funds will be
obligated to purchase 2,500,000 Shares at a price of $.50 per share and
2,500,000 Warrants for an aggregate purchase price of $1,250,000.

         In October 1997, eight of the Company's non-employee directors loaned
the Company an aggregate of $46,200 in order for the Company to continue
operations pending completion of the Financing. A total of $40,425 was repaid,
without interest, to seven of these non-employee directors from the proceeds of
the First Closing, and the balance of $5,775 was converted into 11,550 shares of
Common Stock at a price of $.50 per share.

         In October and November 1997, MJK and principals of MJK loaned the
Company an aggregate of $258,000 in order for the Company to continue operations
pending completion of the Financing. A total of $206,000 was repaid, without
interest, to MJK from the proceeds of the First Closing, and the balance of
$52,000 was converted into 104,000 Shares and 104,000 Warrants in the first
closing at a price of $.50 per share.

         As a condition to the First Closing, the Company's board of directors
(the "Board") was reduced from ten directors to five directors, and all of the
non-employee directors of the Company, other than Daniel Pelak and Kevin Roberg,
resigned from the Board. In addition, all of the non-employee directors of the
Company agreed to cancel all options or warrants to purchase shares of Common
Stock held by them (except for certain options to purchase an aggregate of
236,333 shares held by APF, LLC ("APF") and Dr. Anthony P. Furnary ("Furnary")
and options to purchase 10,000 shares, exercisable at $1.00 per share held by
each of William W. Chorske and William Knopf, M.D.). Under the Purchase
Agreement, the Company has also agreed, so long as the Purchasers own or have
the right to acquire at least 20% of the then outstanding shares of Common
Stock, that (a) the Company shall maintain the number of directors who
constitute the Board of Directors at five; (b) so long as the Funds own at least
2.5% of the then outstanding shares of Common Stock, the Company shall maintain
on the Board one director nominee to be designated by the Funds; and (c) for a
period of three years from the date of the Purchase Agreement, the Company shall
maintain on the Board of Directors one director nominee to be designated by MJK,
which nominee is to be mutually acceptable to the Company and MJK (the "MJK
Director").

         The Company agreed to a number of covenants under the Purchase
Agreement. So long as the Purchasers own or have the right to acquire at least
20% of the outstanding shares of Common Stock, the Company has agreed not to do
any of the following without the consent of the Funds and the MJK Director: (a)
sell Common Stock or any rights or securities convertible into or exercisable or
exchangeable for Common Stock at a purchase, exercise or conversion

<PAGE>


price, as the case may be, of less than $1.00 per share of Common Stock for a
period of three years from the date of the Purchase Agreement; (b) issue any
securities senior to the Common Stock; (c) effect any reclassification, capital
reorganization or other change of outstanding shares of capital stock of the
Company; (d) merge, consolidate or enter into any other business combination of
the Company with or into another entity (other than a merger of a wholly owned
subsidiary, in which merger the Company shall be the surviving entity); (e)
sell, lease or otherwise dispose of all or substantially all of its assets; or
(f) liquidate, dissolve or wind-up the Company.

         All of the Shares and the shares of Common Stock issuable upon exercise
of the Warrants (the "Warrant Shares") are "restricted stock," as defined in the
rules promulgated under the Securities Act of 1933, as amended (the "Securities
Act"). The Shares and Warrant Shares have certain demand and "piggyback"
registration rights under the Securities Act and the rules and regulations
promulgated thereunder as more particularly set forth in Section 4 of the
Purchase Agreement and the Company has agreed not to grant any registration or
similar rights for a period of three years. The Company is required to file a
Registration Statement under the Securities Act by December 14, 1997 registering
the resale of the Shares and Warrant Shares issued on November 14, 1997 and
November 21, 1997. The Company will also be required to register the resale of
any Shares and Warrant Shares issued in subsequent closings.

         As conditions to the First Closing, the Company also amended certain
agreements between the Company and various third parties, including (a)
Medtronic, Inc. ("Medtronic"); (b) The Atlanta Cardiology Group, P.C. ("ACG");
(c)APF and Furnary; (d) the holders of the Company's Convertible Promissory
Notes, dated July 21, 1997, in the aggregate principal amount of $500,000 (the
"July Bridge Notes"); and (e) the employment agreement with David J. Chinsky,
the Company's President and Chief Executive Officer. These amendments are
described below.

         MEDTRONIC, INC. The Company's Convertible Promissory Note, dated May
         12, 1997, in the principal amount of $1,000,000 held by Medtronic (the
         "Medtronic Note") was amended to provide that: (a) no interest will
         accrue thereunder and accrued interest will be forfeited; (b) principal
         will not become due until May 12, 2002; (c) the conversion price of the
         Medtronic Note is $1.50 per share; and (d) the Company will not be
         obligated to issue any additional warrants to Medtronic under the
         Medtronic Note. The warrant, dated May 12, 1997, to purchase 100,000
         shares of Common Stock held by Medtronic (the "Medtronic Warrant") was
         amended to provide that the exercise price is $.50 per share and that
         there was no other adjustment to the exercise price or the number of
         shares covered by the Medtronic Warrant as a result of the transactions
         contemplated by or required to be completed in connection with the
         Purchase Agreement. In addition, Medtronic waived the restrictions on
         registration rights contained in Section 8.4 of the Investment
         Agreement, dated December 26, 1995, waived its right of first refusal
         to purchase Shares or acquire Warrants, agreed not to exercise and to
         otherwise waive any of its registration rights until January 1, 2000,
         waived its superior position with respect to an underwriter's cutback
         of piggyback registration rights and waived its right of first refusal
         on the sale of the Company in certain circumstances.

         THE ATLANTA CARDIOLOGY GROUP, P.C. The Company's Convertible
         Subordinated Note, dated March 28, 1997, in the principal amount of
         $2,250,000 held by ACG (the "ACG Note") was amended to provide that no
         interest will accrue thereunder and that any accrued interest shall be
         forfeited. In addition, ACG agreed that there was no adjustment to the
         conversion price of the ACG Note or the number of shares issuable upon
         conversion of the ACG Note as a result of the transactions contemplated
         by or required to be completed in connection with the Purchase
         Agreement. ACG also agreed not to exercise and to otherwise waive any
         of its registration rights prior to January 1, 2000 and waived its
         right to designate a person to attend meetings of the Board.

         APF, LLC AND ANTHONY P. FURNARY, M.D. The Consulting Agreement, dated

         Company's obligation to make milestone royalty payments under the
         Modification Agreement, dated March 25, 1997, in the aggregate amount
         of $450,000 was terminated. The Non-Statutory Stock Option Agreement,
         dated March 4, 1997, between the Company and APF covering 550,000
         shares of Common Stock was amended to reduce the number of shares to
         200,000 and the exercise price to $1.00 per share. APF and Furnary also
         agreed (a) not to exercise and to otherwise waive any of their
         registration rights under the foregoing option or the other options
         held by them to purchase an aggregate of an additional 36,333 shares
         until January 1, 2000; (b) not to sell or otherwise transfer any shares
         of Common Stock purchased upon exercise of any of such options prior to
         January 1, 2000; and (c) that there was no other adjustment to the
         exercise price of such options or the number of shares issuable upon
         exercise thereof as a result of the transactions contemplated by or
         required to be completed in connection with the Purchase Agreement.
         Furnary also waived his right under the Master Agreement, dated March
         25, 1997, to be nominated for election to the Company's Board of
         Directors and agreed that his observer status is only exercisable by
         him personally.

         JULY 1997 BRIDGE NOTES. The holders of the July Bridge Notes and the
         warrants issued in connection with the issuance of the July Bridge
         Notes (the "July Bridge Warrants") agreed to convert all principal due
         under such notes into shares of Common Stock at a conversion price of
         $2.00 per share, in full satisfaction and discharge of such notes. Such
         holders also agreed that the Company has no obligation to (a) pay cash
         or issue any shares of Common Stock with respect to interest on the
         July Bridge Notes; or (b) issue any additional warrants thereunder. The
         July Bridge Warrants have been amended to provide that the exercise
         price is $2.00 per share and that there was no other adjustment to the
         exercise price of such warrants or the number of shares issuable upon
         exercise thereof as a result of the transactions contemplated by or
         required to be completed in connection with the Purchase Agreement.
         Holders of the July Bridge Notes further agreed not to exercise and to
         otherwise waive any of their registration rights prior to January 1,
         2000.

         WHEREAS, the Company proposes to issue and sell to the Purchasers
shares (individually, a "SHARE" and, collectively, the "SHARES") of common
stock, without par value, of the Company (the "COMMON STOCK") and to issue
warrants (the "WARRANTS"), substantially in the form of Exhibit A hereto, to
purchase shares of Common Stock (the "WARRANT SHARES");

         WHEREAS, the Company proposes to issue and sell for cash an aggregate
of up to 9,000,000 Shares and to issue Warrants to purchase up to 9,000,000

         WHEREAS, the First Closing shall relate to the sale of 2,500,000 Shares
and Warrants, any Interim Closings (which shall be deemed part of the First
Closing) shall relate to an aggregate of up to 2,000,000 Shares and Warrants and
the Second Closing (each as defined in Section 1(b) shall relate to up to
4,500,000 Shares and Warrants;

         WHEREAS, the Company proposes to issue and sell at the First Closing,
in consideration of the cancellation of certain indebtedness, an additional

         NOW THEREFORE, in consideration of the above recitals and the mutual
covenants set forth herein, the parties hereto agree as follows:


<PAGE>


         1. Sale of Stock and Delivery of Warrants; Closings.

         (a) Purchase and Sale. Subject to the terms and conditions hereof, the
Company shall issue and sell to each of the Purchasers, and each Purchaser,
severally, shall purchase from the Company, with respect to the First Closing
and the Second Closing (each as defined below), the number of Shares set forth
on such Purchaser's signature page hereto at a purchase price of $0.56 per
Share; provided, however, that the purchase price per Share shall be $0.50 with
respect to (i) the Shares purchased by Special Situations Private Equity Fund,
L.P., Special Situations Fund III, L.P. and Special Situations Cayman Fund, L.P.
(collectively, the "FUNDS"), and (ii) the 104,000 Shares to be delivered as
provided in Section 1(c)(ii) hereof to the Purchasers designated as noteholders
on the signature pages hereto. The Company shall deliver to each Purchaser, at
each Closing, Warrants for such number of Warrant Shares as shall be equal to
the number of Shares being purchased by such Purchaser at such Closing. Each
Purchaser's obligation to purchase Shares is separate and distinct from that of
each other Purchaser, and no Purchaser shall be required to purchase more than
the number of Shares specifically set forth on such Purchaser's signature page.
A Purchaser that shall purchase Shares in an Interim Closing or in the Second
Closing, but not the First Closing, shall become a Purchaser by executing a copy
of this Agreement after the First Closing, but prior to such Interim or Second
Closing, as the case may be.

         (b) Closings.

                  (i) Subject to the satisfaction (or waiver) of the conditions
         set forth in Sections 6 and 7, the first Closing (the "FIRST CLOSING")
         of the purchase and sale of Shares shall occur with respect to up to
         2,604,000 Shares and Warrants to purchase up to 2,604,000 shares of
         Common Stock at the offices of Hertzog, Calamari & Gleason, 100 Park
         Avenue, New York, New York, at 10:00 A.M. on November 14, 1997, or such
         later date as may be mutually agreed upon by the parties.

                  (ii) Subject to the satisfaction (or waiver) of the conditions
         set forth in Sections 6 and 7, a Closing or Closings (each, an "INTERIM
         CLOSING") of the purchase and sale of up to an aggregate of 2,000,000
         Shares and Warrants to purchase up to 2,000,000 shares of Common Stock
         may be held during the period (the "INTERIM PERIOD") from November 15,
         1997, through and including November 21, 1997. Such Interim Closing or
         Interim Closings shall occur at the offices of


<PAGE>


         Oppenheimer Wolff & Donnelly at 10:00 A.M. on such date or dates during
         the Interim Period as may be mutually agreed upon by the Company and
         the Purchasers in any such Closing. The Shares that shall be sold and
         the Warrants that shall be delivered at any Interim Closing shall be
         deemed to have been purchased and sold in the First Closing.

                  (iii) Subject to the satisfaction (or waiver) of the
         conditions set forth in Sections 6, 7 and 8, the second Closing (the
         "SECOND CLOSING") of the purchase and sale of Shares shall occur at the
         offices of Hertzog, Calamari & Gleason with respect to up to 4,500,000
         Shares and Warrants to purchase up to 4,500,000 shares of Common Stock
         within fifteen days following satisfaction or waiver of each of the
         conditions set forth in Sections 6, 7 and 8. The Company shall give
         each Purchaser at least fifteen days prior written notice of the date
         and time of the Second Closing.

                  (iv) Notwithstanding anything to the contrary contained
         herein, the First Closing in no event shall occur later than November
         14, 1997, and the Second Closing in no event shall occur later than
         January 30, 1998.

                  (v) The date of each Closing shall be hereinafter referred to
         as a "CLOSING DATE."

                  (c) Delivery.

                  (i) Except as provided in Section 1(c)(ii), the Company shall,
         at each Closing, deliver to each Purchaser a stock certificate
         representing the Shares purchased by such Purchaser and Warrants for
         the Warrant Shares to be delivered to such Purchaser, against payment
         of the purchase price therefor by check, payable to the order of the
         Company, or by wire transfer of immediately available funds to the
         Company in accordance with the Company's wiring instructions.

                  (ii) At the First Closing, the Company shall deliver to the
         Purchasers designated as noteholders on the signature pages hereto
         stock certificates representing an aggregate of 104,000 Shares and
         Warrants to purchase 104,000 shares of Common Stock, in the respective
         denominations listed on the signature pages hereto, against delivery
         of, and in full satisfaction and discharge of, those certain promissory
         notes, dated October 1, 1997, issued by the Company in


<PAGE>


         favor of such Purchasers in the aggregate principal
         amount of $52,000.

                  2. Representations and Warranties of Purchasers. Each of the
         Purchasers (except with respect to Section 2(i) which relates only to
         the Purchaser named therein) represents and warrants, severally, to the
         Company as follows:

                  (a) Authorization. The Purchaser has the necessary power and
         authority to execute and deliver this Agreement and to perform its
         obligations hereunder. The execution and delivery of, and the
         performance under, this Agreement by the Purchaser will not conflict
         with any rule, regulation, judgment or agreement applicable to the
         Purchaser.

                  (b) Investment Purpose. The Purchaser is purchasing the Shares
         and acquiring the Warrants, and will purchase the Warrant Shares
         (together with the Shares and the Warrants, the "SECURITIES"), for
         investment purposes only and not with a present view to, or for sale in
         connection with, a distribution thereof within the meaning of the
         Securities Act. The Purchaser understands that it must bear the
         economic risk of this investment indefinitely, unless the Securities
         are registered pursuant to the Securities Act and any applicable state
         securities or blue sky laws or an exemption from such registration is
         available. Notwithstanding anything in this Section 2(b) to the
         contrary, the Purchaser, by making the representations herein, does not
         agree to hold the Securities for any minimum or other specific term and
         reserves the right to dispose of such Securities at any time in
         accordance with or pursuant to registration or an exemption therefrom
         under the Securities Act and any applicable state securities or blue
         sky laws.

                  (c) Reliance On Exemptions. The Purchaser understands that the
         Securities are being offered and sold in reliance upon specific
         exemptions from the registration requirements of Federal and state
         securities laws and that the Company is relying upon the truth and
         accuracy of the representations and warranties of the Purchaser set
         forth herein in order to determine the availability of such exemptions
         and the eligibility of the Purchaser to acquire the Securities.

                  (d) Information. The Purchaser has been furnished all
         documents relating to the business, finances and operations of the
         Company which the Purchaser requested from the Company. The Purchaser
         has been afforded the opportunity to ask questions of the Company's


<PAGE>


         representatives concerning the Company in making the decision to
         purchase the Shares and acquire the Warrants, and such questions have
         been answered to its satisfaction. The Purchaser acknowledges having
         received a copy of the Company's Private Placement Memorandum, dated
         October 24, 1997, as amended by the supplement thereto dated November
         10, 1997, including the Exhibits thereto, relating to the offer and
         sale of the Securities (as supplemented, the "MEMORANDUM"). However,
         neither the foregoing nor any other due diligence investigation
         conducted by the Purchaser or on its behalf shall limit, modify or
         affect the representations and warranties of the Company in Section 3
         of this Agreement or the right of the Purchaser to rely thereon.

                  (e) Governmental Review. The Purchaser understands that no
         Federal or state agency or any other government or governmental agency
         has passed upon or made any recommendation or endorsement of the
         Securities.

                  (f) Purchaser's Qualifications. The Purchaser is an
         "accredited investor" as defined in Rule 501 under Regulation D of the
         Securities Act ("REGULATION D"). The Purchaser is capable of evaluating
         the merits and risks of an investment in the Securities and is
         financially capable of bearing a total loss of the investment made
         pursuant to this Agreement.

                  (g) Restrictions on Transfer. The Purchaser understands that
         it may not transfer any of the Securities unless such Securities are
         registered under the Securities Act or unless an exemption from
         registration and qualification requirements are available under the
         Securities Act and applicable state securities laws. The Purchaser
         understands that certificates representing the Shares, the Warrants and
         the Warrant Shares shall bear the following, or a substantially
         similar, legend until such time as they have been registered under the
         Securities Act or otherwise may be sold under Rule 144 under the
         Securities Act ("RULE 144"):

                  THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933 (THE "ACT") OR UNDER ANY
                  STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE SOLD,
                  TRANSFERRED OR ASSIGNED EXCEPT AS PERMITTED UNDER THE ACT AND
                  APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
                  EXEMPTION THEREFROM. UNLESS THE SECURITIES ARE SOLD PURSUANT
                  TO AN EFFECTIVE REGISTRATION STATEMENT, THE ISSUER OF THESE
                  SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND
                  SUBSTANCE SATISFACTORY TO THE ISSUER TO


<PAGE>


                  THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN
                  COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES
                  LAWS.

                  (h) Residence. The Purchaser is a resident of the jurisdiction
         set forth under its name on its signature page hereto.

                  (i) Investment Company. Special Situations Fund III, L.P. is
         registered as an "investment company" under the Investment Company Act
         of 1940.

                  3. Representations and Warranties of Company. Except as set
         forth on the Schedule of Exceptions attached hereto as Exhibit B, the
         Company represents and warrants to each Purchaser as follows:

                  (a) Organization and Good Standing. The Company is a
         corporation duly organized, validly existing and in good standing under
         the laws of the State of Minnesota, and has all necessary corporate
         power and authority to own or lease its assets and to carry on its
         business as now being conducted and presently proposed to be conducted.
         The Company is duly qualified to do business as a foreign corporation
         and is in good standing in each jurisdiction in which its ownership or
         leasing of assets, or the conduct of its business, makes such
         qualification necessary, except where the failure to be so qualified
         would not have a material adverse effect on the Company. The Company
         has no subsidiaries and no equity interests in any corporation,
         partnership, joint venture or other entity.

                  (b) Requisite Power and Authorization. The Company has all
         necessary corporate power and authority to execute and deliver this
         Agreement and to perform its obligations hereunder, including without
         limitation the issuance of the Securities. Except for approval by the
         stockholders of the Company of the Amendment (as defined in Section
         5(k) below), which approval will be required prior to the Second
         Closing, all corporate action of the Company required for the execution
         and delivery of this Agreement and the Warrants and issuance and
         delivery of the Securities has been duly and effectively taken, and no
         further actions, authorizations or consents, including, without
         limitation, any consents of the stockholders of the Company, are
         required. Each of this Agreement and the Warrants constitutes the valid
         and binding obligation of the Company, enforceable against the Company
         in accordance with its terms, except (i) as limited by applicable
         bankruptcy, insolvency, reorganization, moratorium or other laws of
         general application affecting enforcement of creditor's rights, (ii) as
         limited by general principles of equity that


<PAGE>


         restrict the availability of equitable remedies and (iii) as the
         indemnity provisions of Section 4(f) of this Agreement may be limited
         by law. The Shares, when issued, delivered and paid for in compliance
         with the provisions of this Agreement, will be validly issued, fully
         paid and non-assessable, free and clear of any and all liens, charges,
         claims or encumbrances. The Warrant Shares, if and when issued,
         delivered and paid for in compliance with the provisions of this
         Agreement and the Warrants will be validly issued, fully paid and
         non-assessable, free and clear of any and all liens, charges, claims or
         encumbrances. The Company has reserved a sufficient number of shares of
         Common Stock necessary for issuance of the Shares and the Warrant
         Shares at the First Closing and, prior to the Second Closing, will have
         reserved a sufficient number of shares of Common Stock necessary for
         issuance of the Shares and the Warrant Shares at the Second Closing.

                  (c) SEC Documents. Since March 16, 1995, the Company has filed
         with the Securities and Exchange Commission (the "SEC") all reports,
         statements, schedules and other documents (collectively, the "SEC
         DOCUMENTS") required to be filed by it pursuant to the Securities Act
         and the Securities Exchange Act of 1934 (the "EXCHANGE ACT"). Since
         October 1, 1996, all SEC Documents required to be filed were timely
         filed. As of their respective dates, the SEC Documents complied in all
         material respects with the requirements of the Securities Act or the
         Exchange Act, as the case may be, and the rules and regulations of the
         SEC promulgated thereunder, and none of the SEC Documents, at the time
         they were filed with the SEC, contained any untrue statement of a
         material fact or omitted to state a material fact required to be stated
         therein or necessary in order to make the statements therein, in light
         of the circumstances under which they were made, not misleading. As of
         their respective dates, the financial statements included in the SEC
         Documents (the "FINANCIAL STATEMENTS") complied as to form in all
         material respects with applicable accounting requirements and the
         published rules and regulations of the SEC with respect thereto. Except
         (i) as may be indicated in the notes to the Financial Statements or
         (ii) in the case of the unaudited interim statements, as permitted by
         Form 10- QSB under the Exchange Act, the Financial Statements have been
         prepared in accordance with U.S. generally accepted accounting
         principles consistently applied and fairly present in all material
         respects the financial position of the Company as of the dates thereof
         and the results of its operations and cash flows for the periods then
         ended (subject, in the case of unaudited statements, to normal
         recurring year-end adjustments and footnotes). Except as set forth in
         the Financial Statements filed with the SEC prior to the date hereof or
         the Memorandum, the Company does


<PAGE>


         not have any liabilities, whether absolute, contingent or otherwise,
         other than (i) liabilities incurred in the ordinary course of business
         subsequent to the date of such Financial Statements and (ii)
         obligations under contracts and commitments incurred in the ordinary
         course of business and not required under generally accepted accounting
         principles to be reflected in such Financial Statements, which
         liabilities and obligations referred to in clauses (i) and (ii),
         individually or in the aggregate, are not material to the financial
         condition or operating results of the Company.

                  (d) Capitalization. The capitalization of the Company as of
         the date hereof is set forth on Schedule 3(d), including (i) the
         authorized capital stock, (ii) the number of shares issued and
         outstanding, (iii) the number of shares reserved for issuance pursuant
         to stock option, employee benefit or other plans, (iv) the number of
         shares reserved for issuance or issuable pursuant to securities
         exercisable for, or convertible into or exchangeable for, any shares of
         Common Stock, (v) the number of outstanding securities convertible into
         or exchangeable for any shares of the Company's capital stock, (vi) the
         number of shares of Common Stock reserved for issuance with respect to
         the sale of the Shares and (vii) the number of shares reserved for
         issuance upon exercise of the Warrants. All outstanding shares of
         capital stock have been duly authorized and validly issued and are
         fully paid and non-assessable. Except as set forth on Schedule 3(d),
         the Company has (i) no outstanding securities convertible into or
         exchangeable for any shares of capital stock of the Company, (ii) no
         rights, options, warrants, calls or other agreements or commitments of
         any nature whatsoever relating to the purchase or other acquisition of
         any shares of its capital stock or securities convertible into or
         exchangeable for any shares of it capital stock or (iii) no shares of
         its capital stock reserved for issuance.

                  (e) No Conflicts. Neither the execution, delivery and
         performance by the Company of this Agreement nor the consummation of
         the transactions contemplated hereby has constituted or resulted in, or
         will constitute or result in, a default under or breach or violation of
         any term or provision of the Articles of Incorporation or bylaws of the
         Company or material contracts to which the Company is a party or
         Federal or state laws, rules or regulations, writs, orders, judgments
         or decrees which are applicable to the Company or its assets.

                  (f) Consents. No approval, consent, order, authorization or
         other action by, or notice to or filing with, any governmental
         authority or regulatory agency or any


<PAGE>


         other person or entity, and no lapse of a waiting period, is required
         in connection with the execution, delivery or performance by the
         Company of this Agreement, the issuance and delivery of any of the
         Securities or any other transactions contemplated hereby, except for
         (i) the filing of a Form D with the SEC, (ii) filings required under
         applicable state "blue sky" laws (which shall be duly filed and
         effective prior to each Closing if so required under such laws) and
         (iii) the filing of an amendment to the Company's Articles of
         Incorporation as set forth in Section 8(a) hereof.

                  (g) No Material Adverse Change. Since December 31, 1996, the
         business of the Company has been operated in the ordinary course and
         substantially consistent with past practice, and, except as disclosed
         in the Memorandum, there has not been any material adverse change in
         the business, assets, financial condition, results of operations,
         affairs or prospects of the Company (a "MATERIAL ADVERSE CHANGE").
         Since December 31, 1996, and except as disclosed in the Memorandum, the
         Company has not (i) paid any obligation or liability or discharged or
         satisfied any liens or encumbrances other than in the ordinary course
         of business; (ii) declared or made any payment or distribution to its
         stockholders or purchased or redeemed any of its shares of capital
         stock or other securities; (iii) mortgaged, pledged or subjected to any
         lien, charge or other encumbrance any of its assets, tangible or
         intangible, except in the ordinary course of business; (iv) sold,
         transferred or leased any of its assets except for fair value in the
         ordinary course of business; (v) increased the annual compensation
         payable to any of its officers or other employees, consultants or
         representatives by greater than $10,000; (vi) cancelled or compromised
         any debt or claim, or waived or released any right of material value;
         (vii) entered into any transaction other than in the ordinary course of
         business; (viii) issued or sold any shares of capital stock or other
         securities or granted any options, warrants or other purchase rights
         with respect thereto that are not disclosed on Schedule 3(d); or (ix)
         agreed to do any of the foregoing (other than pursuant hereto).

                  (h) Litigation. There is no action, suit, proceeding or
         investigation pending or, to the Company's knowledge, currently
         threatened against the Company or any of its directors or officers, in
         their capacities as such, (i) that questions the validity of this
         Agreement or the issuance of the Securities, or the right of the
         Company to enter into this Agreement or to consummate the transactions
         contemplated hereby, or (ii) that might result, either individually or
         in the aggregate, in any Material Adverse Change or in any change in
         the current equity ownership of


<PAGE>


         the Company. The Company is not a party or subject to the provisions of
         any order, writ, injunction, judgment, stipulation or decree of any
         court, administrative agency, commission, regulatory authority, other
         government agency or instrumentality.

                  (i) No Default. The Company is not in violation of or default
         under any provision of its Articles of Incorporation or bylaws or other
         constituent documents or in default (or, with notice or the lapse of
         time, would be in default) under any material agreement, contract,
         commitment or instrument to which it is a party or by which it or its
         properties or assets is bound or affected. To the Company's knowledge,

         violation of any material contract, commitment or instrument to which
         the Company is a party or by which any of its properties or assets are
         bound or affected.

                  (j) Compliance with Laws. The Company is in compliance with
         all laws (including, without limitation, environmental laws),
         ordinances, rules and regulations, judgments, decrees or orders of any
         regulatory authority or other governmental or administrative body or
         instrumentality, whether domestic or foreign. The Company has not
         during the past three years received any notice relating to any
         violation or potential violation of applicable law or regulations.

                  (k) Title. The Company has good and marketable title to all
         real and personal property owned by it which is material to the
         business of the Company, in each case free and clear of all liens,
         encumbrances and defects. Any property, real or personal, held under
         lease by the Company is held by it under valid and enforceable leases.

                  (l) Intellectual Property. The Company owns, or possesses

         applications, trademarks, trademark applications, trade names, service
         marks, copyrights, copyright applications, licenses, permits, know-how
         (including trade secrets and other unpatented and/or unpatentable
         proprietary or confidential information, systems or procedures) and
         other similar rights and proprietary knowledge (collectively, the
         "INTANGIBLES") necessary for the conduct of its business. To the
         Company's knowledge, the Company has not infringed, nor does it
         currently infringe, nor is it in conflict with any right of any other

                  (m) Registration Rights. The only registration rights,
         including piggyback rights, granted (or agreed to be granted) to any
         person or entity other than the Purchasers are set forth on the
         Schedule of Exceptions. None of the registration rights disclosed on
         the Schedule of Exceptions are senior in priority to the registration
         rights provided for in this Agreement. All of the registration rights
         (including, without limitation, any piggyback rights which would have
         permitted the registration of any shares under the registration
         statement to be filed pursuant to Section 4 of this Agreement) have
         been satisfied in full by the registration on Form S-3 indicated on
         such Schedule or have been waived until January 1, 2001.

                  (n) OTC Bulletin Board. The Common Stock is traded by means of
         the National Association of Securities Dealers, Inc. (the "NASD") OTC
         Bulletin Board(R) service (the "OTCBB"). The issuance and sale of the
         Securities will not, when issued and sold in accordance with this
         Agreement and the Warrants, as the case may be, violate any Rule of the
         NASD applicable to the Company or the Common Stock. The Company has not
         received notification, written or oral, that the Company has failed to
         satisfy any requirement of the NASD relating to the trading of the
         Common Stock in the OTCBB.

                  (o) Registration Statement. The Company is currently eligible
         to register the resale of its Common Stock under the Securities Act
         pursuant to a registration statement on Form SB-2. There exist no facts
         or circumstances that would inhibit or delay the preparation and filing
         of a registration statement on Form SB-2 with respect to the Shares and
         the Warrant Shares.

                  (p) No Misrepresentation. No representation or warranty by the
         Company in this Agreement (including any Exhibit or Schedule hereto)
         and no statements of the Company contained in any document (including
         without limitation any SEC Document), certificate, schedule or other
         information furnished or to be furnished by or on behalf of the Company
         pursuant to this Agreement or in connection with the transactions
         contemplated hereby, including without limitation the Memorandum,
         contains or shall contain any untrue statement of material fact or
         omits or shall omit to state a material fact required to be stated
         therein or necessary in order to make such statements, in light of the
         circumstances under which they were made, not misleading. Except for
         the transactions contemplated hereby, and except as disclosed in the
         Memorandum, no event or circumstance has occurred or exists with
         respect to the Company or its business, affairs, assets, properties,
         prospects, operations or financial condition which has not been
         publicly


<PAGE>


         disclosed, but which, under applicable law, rule or regulation, would
         be required to be disclosed by the Company in a registration statement
         filed on the date hereof by the Company under the Securities Act with
         respect to the primary issuance of the Company's securities. The
         Company has delivered true and complete copies of all documents
         requested by the Purchasers.

                  (q) Anti-Dilution and Other Shares. No stockholder of the
         Company or other person or entity has any preemptive right of
         subscription or purchase or contractual right of first refusal or
         similar right with respect to any of the Securities which has not been
         waived. Issuance of the Securities will not result in the issuance of
         any additional shares of Common Stock or the triggering of other
         anti-dilution or similar rights contained in any options, warrants,
         debentures or other securities or agreements of the Company.
         Consummation of the transactions contemplated by the agreements set
         forth as Exhibit D and the transactions contemplated by Schedule 6(j)
         shall not trigger any anti-dilution or similar rights or price or other
         adjustments which have not been waived. All of the transactions set
         forth on Schedule 6(j) are reflected in the agreements included as
         Exhibit D hereto.

                  (r) No Brokers or Finders. No person or entity has or will
         have, as a result of any act or omission by the Company, any right,
         interest or valid claim against any Purchaser for any commission, fee
         or other compensation as a finder or broker, or in any similar
         capacity, in connection with the transactions contemplated by this
         Agreement.

                  (s) Acknowledgment of Dilution. The number of Warrant Shares
         issuable upon exercise of the Warrants may increase in certain
         circumstances, including when the bid price of the Common Stock
         declines. The Company acknowledges that its obligation to issue Warrant
         Shares upon exercise of the Warrants in accordance with the terms of
         the Warrants is absolute and unconditional, regardless of the dilution
         that such issuance may have on the ownership interests of other
         stockholders. The Company acknowledges that issuance of the Securities
         will result in substantial dilution to existing stockholders of the
         Company. Taking the foregoing into account, the Board of Directors has
         determined that the issuance of the Shares and the Warrants hereunder
         and the consummation of the other transactions contemplated hereby are
         in the best interests of the Company and its stockholders.

                  (t) Independent Committee. A duly authorized committee of the
         Board of Directors of the Company comprised solely of "disinterested
         directors" as defined in Section


<PAGE>


         302A.673 of the Minnesota Business Corporation Act has unanimously
         approved this Agreement and the Warrants and the transactions
         contemplated hereby.

                  (u) Issuing Public Corporation. The Company has at least 50
         "shareholders". For purposes hereof, a "shareholder" means a person
         registered on the books or records of the Company or its transfer agent
         or registrar, as the case may be, as the owner of whole or fractional
         shares of Common Stock.

                  (v) Change of Control Payments. Neither the execution,
         delivery and performance by the Company of this Agreement or the
         Warrants nor the consummation of any of the transactions contemplated
         hereby shall require any payment by the Company, in cash or kind, under
         any agreement, plan, policy, commitment or other arrangement. There are
         no agreements, plans, policies, commitments or other arrangements with
         respect to any compensation, benefits or consideration which will be
         materially increased, or the vesting of benefits of which will be
         materially accelerated, as a result of the execution and delivery of
         this Agreement or the Warrants or the occurrence of any of the
         transactions contemplated hereby. There are no payments or other
         benefits, the value of which will be calculated on the basis of any of
         the transactions contemplated by this Agreement.

                  4. Registration Rights.

                           (a) Definitions. For purposes of this Section 4:

                           (i) "Register", "registered" and "registration" refer
                  to a registration effected by preparing and filing a
                  registration statement in compliance with the Securities Act,
                  including a registration statement pursuant to Rule 415 and
                  Rule 416 under such Act (or any successor rules), and the
                  declaration or ordering of effectiveness of such registration
                  statement by the SEC.

                           (ii) "Registrable Securities" means the Shares and
                  all shares of Common Stock issued or issuable as Warrant
                  Shares, and any shares of Common Stock issued or issuable,
                  from time to time (with any adjustments), as a distribution
                  on, in exchange for or otherwise with respect to the Shares or
                  Warrant Shares.

                           (iii) "Holder" means any person owning of record
                  Registrable Securities or any assignee of record of such
                  Registrable Securities to whom rights under this Section 4
                  have been assigned in accordance with Section


<PAGE>


                  9(e) of this Agreement and, as the case may be, the terms of
                  the Warrants.

                           (b) Shelf Registration.

                           (i) The Company, within 30 days following each
                  Closing Date, shall file a shelf registration statement under
                  the Securities Act on Form SB-2 (or, if not available, on such
                  Form as is then available to effect a registration of all
                  Registrable Securities, subject to the consent of the
                  Purchasers holding a majority of the Registrable Securities)
                  covering, and shall obtain all such qualifications and
                  compliances as may be required and as would permit the sale
                  and distribution of, all Registrable Securities issued (or, in
                  the case of Warrant Shares, issuable) at each respective
                  Closing, and shall use its best efforts to secure the
                  effectiveness of such registration statements no later than 90
                  days following each respective Closing Date. The requirement
                  to register securities sold at the Second Closing may be
                  satisfied by amending the shelf registration statement which
                  shall have been filed pursuant to this Section 4(b) with
                  respect to securities sold at the First Closing.

                           (ii) The Company shall pay all expenses incurred in
                  connection with any registration, qualification and compliance
                  (excluding underwriters' and brokers' discounts and
                  commissions), including, without limitation, all filing,
                  registration and qualification fees, printer and accounting
                  fees and reasonable fees and disbursements of one counsel for
                  the selling Holder or Holders and of counsel for the Company.

                           (iii) The Company shall use its best efforts to cause
                  the registration statement or statements filed pursuant to
                  this Section 4(b) to remain effective until the earlier of (A)
                  the date on which all Registrable Securities shall have been
                  sold or (B) the date on which all Registrable Securities, in
                  the opinion of counsel to Special Situations Private Equity
                  Fund, L.P., may be sold immediately to the public in any
                  single three-month period pursuant to Rule 144.

                           (c) Piggyback Registrations.

                           (i) The Company shall be required to notify a Holder
                  in writing at least 20 days prior to the Company's filing of
                  any registration statement under the Securities Act for
                  purposes of effecting an underwritten public offering of
                  Common Stock (including, without limitation, registration
                  statements


<PAGE>


                  relating to secondary offerings of Common Stock), and shall
                  afford a Holder an opportunity to include in such registration
                  statement all or any part of the Registrable Securities then
                  held by such Holder. A Holder desiring to include all or any
                  part of its Registrable Securities shall, within 15 days after
                  receipt of the above-described notice from the Company, notify
                  the Company in writing as to the number of Registrable
                  Securities to be included in such registration statement. If a
                  Holder shall decide not to include all of its Registrable
                  Securities in such registration statement, such Holder
                  nevertheless shall continue to have the right to include any
                  Registrable Securities in any subsequent registration
                  statement or statements as may be filed by the Company with
                  respect to underwritten public offerings of Common Stock, in
                  each instance upon the terms and conditions set forth herein.
                  The right to registration of Registrable Securities under this
                  Section 4(c) shall not be construed to limit in any way the
                  obligation of the Company to register the Registrable
                  Securities under Section 4(b).

                           (ii) The right of a Holder to include Registrable
                  Securities in a registration pursuant to this Section 4(c)
                  shall be conditioned upon such Holder's participation in such
                  underwriting and the inclusion of such Holder's Registrable
                  Securities in the underwriting to the extent provided herein.
                  If less than all securities of Holders or other persons (other
                  than the Company) included in a request for registration can
                  be included in a registration based on the good faith
                  determination of the managing underwriter, the allocation
                  among such Holders and other persons will be on a pro rata
                  basis according to the relation that the number of Registrable
                  Securities owned by each such Holder and the number of shares
                  of Common Stock owned by each such other person bears to the
                  total number of shares of Common Stock outstanding. If any
                  Holder shall disapprove of the terms of any such underwriting,
                  such Holder may elect to withdraw therefrom by written notice
                  to the Company delivered at least five business days prior to
                  the effective date of the registration statement. The Company
                  shall exclude from the registration any Registrable Securities
                  so withdrawn.

                           (iii) Notwithstanding the other provisions of this
                  Section 4(c), (A) the Company shall not be required to include
                  any Registrable Securities in any registration under Section
                  4(c) for any Holder who shall be able to sell all of such
                  Holder's Registrable Securities during


<PAGE>


                  a three-month period, beginning on the date such notice shall
                  be received by such Holder, pursuant to Rule 144 (or any
                  similar rule or regulation); (B) the Company shall not be
                  required to give such notice with respect to, or to include
                  Registrable Securities in, any such registration which shall
                  be primarily (1) a registration of a stock option plan or
                  other employee benefit plan or of securities issued or
                  issuable pursuant to any such plan, or (2) a registration of
                  securities proposed to be issued in exchange for securities or
                  assets of, or in connection with a merger or consolidation
                  with, another corporation; and (C) the Company may, in its
                  sole discretion, withdraw any such registration statement and
                  abandon the proposed offering in which any such Holder shall
                  have requested to participate.

                           (iv) The Company shall pay all expenses incurred in
                  connection with a piggyback registration pursuant to this
                  Section 4(c) (excluding underwriters' and brokers' discounts
                  and commissions), including, without limitation, all filing,
                  registration and qualification fees, printer and accounting
                  fees and reasonable fees and disbursements of one counsel for
                  the selling Holder or Holders and of counsel for the Company.

                  (d) Obligations of the Company. Whenever required to effect
         the registration of any Registrable Securities under this Agreement,
         the Company shall, as expeditiously as possible:

                           (i) Prepare and file with the SEC a registration
                  statement with respect to such Registrable Securities and use
                  its best efforts to cause such registration statement to
                  become effective.

                           (ii) Prepare and file with the SEC such amendments
                  and supplements to such registration statement and the
                  prospectus included therein as may be necessary to keep the
                  registration statement effective and comply with the
                  provisions of the Securities Act with respect to the
                  disposition of all Registrable Securities covered by such
                  registration statement for the period set forth in Section
                  4(b)(iii).

                           (iii) Furnish to each Holder (1) promptly after
                  filing with the SEC, one copy of such registration statement
                  and any amendments thereto, including each prospectus
                  contained therein, (2) on the date of effectiveness of such
                  registration statement or amendment, a notice that such
                  registration statement or amendment has been declared
                  effective and (3) such


<PAGE>


                  number of copies of a prospectus, including a preliminary
                  prospectus, in conformity with the requirements of the
                  Securities Act, and all amendments thereto, and such other
                  documents as any Holder may reasonably request, in order to
                  facilitate the disposition of the Registrable Securities owned
                  by such Holder which shall have been included in such
                  registration statement. In the case of a registration
                  statement to be filed pursuant to Section 4(b), the Company
                  also shall furnish to the Funds each letter written by or on
                  behalf of the Company to the SEC or the staff of the SEC and
                  each correspondence therefrom.

                           (iv) Use its best efforts to register and qualify the
                  Registrable Securities covered by such registration statement
                  under any applicable securities or "blue sky" laws of such
                  states and jurisdictions as shall be reasonably requested by
                  any Holder, and maintain the effectiveness of such
                  registrations and qualifications, provided, that the Company
                  shall not be required in connection therewith or as a
                  condition thereto to qualify to do business or to file a
                  general consent to service of process in any such states or
                  jurisdictions.

                           (v) Notify each Holder of Registrable Securities
                  included in such registration statement, at any time when a
                  prospectus relating thereto shall be required to be delivered
                  under the Securities Act, of the happening of any event as a
                  result of which the prospectus included in such registration
                  statement shall include an untrue statement of a material fact
                  or omit 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, and, upon such
                  notice, the Company shall promptly correct such misstatement
                  or omission and deliver to each Holder copies of the corrected
                  prospectus.

                           (vi) Take all reasonable actions required to prevent
                  the entry of any stop order issued or threatened by the SEC or
                  any state regulatory authority with respect to any
                  registration statement covering Registrable Securities, and
                  notify each Holder of any such stop order or take all
                  reasonable actions to remove it if entered.

                           (vii) Permit one counsel designated by the Holders to
                  review such registration statement and all amendments and
                  supplements thereto in a reasonable period of time prior to
                  their filing with the SEC, and not file any document in a form
                  to which such counsel shall reasonably object.

                  (e) Furnish Information. It shall be a condition precedent to
         the obligations of the Company to take any action pursuant to Section
         4(b) or Section 4(c) that a selling Holder shall furnish to the Company
         such information regarding such Holder, the Registrable Securities held
         by such Holder and the intended method of disposition of such
         Securities as reasonably shall be required to effect the registration
         of the Registrable Securities.

                  (f) Indemnification. In the event that any Registrable
         Securities shall be included in a registration statement under this
         Agreement:

                           (i) To the extent permitted by law, the Company shall
                  indemnify and hold harmless each Holder, the partners,
                  stockholders, officers and directors of each Holder, any
                  underwriter (as defined in the Securities Act) for such Holder
                  and each person, if any, who controls such Holder or
                  underwriter within the meaning of the Securities Act or the
                  Exchange Act (each, an "INDEMNIFIED PERSON") against any joint
                  or several losses, claims, damages, liabilities or expenses
                  (together with actions, proceedings or inquiries by any
                  regulatory or self-regulatory organization, whether commenced
                  or threatened, in respect thereof, "CLAIMS") to which any of
                  them may become subject insofar as such Claims arise out of or
                  are based upon (i) any untrue statement or alleged untrue
                  statement of a material fact contained in a registration
                  statement or 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, (ii) any untrue
                  statement or alleged untrue statement of a material fact
                  contained in any preliminary prospectus if used prior to the
                  effective date of such registration statement, or contained in
                  the final prospectus (as amended or supplemented, if the
                  Company shall file any amendment thereof or supplement thereto
                  with the SEC) or the omission or alleged omission to state
                  therein any material fact necessary to make the statements
                  made therein, in light of the circumstances under which the
                  statements therein were made, not misleading, or (iii) any
                  violation or alleged violation by the Company of the
                  Securities Act, the Exchange Act, any state securities law or
                  any rule or regulation thereunder relating to the offer or
                  sale of the Registrable Securities (the matters in the
                  foregoing clauses (i) through (iii) being, collectively,
                  called "VIOLATIONS"). The Company shall reimburse each
                  Indemnified Person for any reasonable legal or other expenses
                  (promptly as such expenses shall be incurred and shall be due
                  and payable)


<PAGE>


                  incurred by such Indemnified Person in connection with
                  investigating or defending any such Claim. The indemnification
                  agreement contained in this Section 4(f)(i) shall not apply
                  (i) to a Claim arising out of or based upon a Violation which
                  shall occur in reliance upon and in conformity with
                  information furnished in writing to the Company by such
                  Indemnified Person expressly for use in such registration
                  statement or any such amendment or supplement thereto; (ii) to
                  amounts paid in settlement of any Claim if such settlement
                  shall be effected without the prior written consent of the
                  Company; and (iii) for the benefit of any Indemnified Person,
                  with respect to any prospectus, if the untrue statement or
                  omission of material fact in any prospectus shall have been
                  corrected on a timely basis and the Indemnified Person shall
                  have failed to utilize such corrected prospectus. This
                  indemnity shall remain in full force and effect regardless of
                  any investigation made by or on behalf of the Indemnified
                  Person and shall survive the transfer of the Registrable
                  Securities by the Purchasers pursuant to Section 9.

                           (ii) In connection with any registration statement in
                  which a Holder shall participate, such Holder, severally and
                  not jointly, shall indemnify and hold harmless the Company,
                  each of its directors, each of its officers who shall sign the
                  registration statement, its employees and agents and each
                  person, if any, who controls the Company within the meaning of
                  the Securities Act or the Exchange Act, any underwriter and
                  any other stockholder selling securities pursuant to such
                  registration statement or any of its directors or officers or
                  any person who controls such underwriter or stockholder within
                  the meaning of the Securities Act or the Exchange Act (each,
                  an "INDEMNIFIED PARTY") against any Claim to which any of them
                  may become subject, under the Securities Act, the Exchange Act
                  or otherwise, insofar as such Claim shall arise out of or
                  shall be based upon any Violation, in each case to the extent
                  (and only to the extent) that such Violation shall occur in
                  reliance upon and in conformity with written information
                  furnished to the Company by such Holder expressly for use in
                  connection with such registration statement. Such Holder shall
                  reimburse the Indemnified Party for any reasonable legal or
                  other reasonable expenses (promptly as such expenses shall be
                  incurred and shall be due and payable) incurred in connection
                  with investigating or defending any such Claim. The indemnity
                  agreement contained in this Section 4(f)(ii) shall not apply
                  to amounts paid in settlement of any Claim if such settlement
                  shall be


<PAGE>


                  effected without the prior written consent of such Holder;
                  and, provided, further, that the total amounts payable by a
                  Holder under this Section 4(f)(ii) shall not exceed the
                  aggregate proceeds (net of discounts or commissions) actually
                  received by such Holder upon the sale of such Holder's
                  Registrable Securities included in such registration
                  statement. Notwithstanding anything to the contrary contained
                  herein, the indemnification agreement contained in this
                  Section 4(f)(ii) shall not inure to the benefit of any person
                  or entity if the untrue statement or omission of material fact
                  in any prospectus shall have been corrected on a timely basis
                  and such person or entity shall have failed to utilize such
                  corrected prospectus.

                           (iii) Promptly after receipt by an Indemnified Person
                  or Indemnified Party (the "INDEMNITEE") under this Section
                  4(f) of notice of the commencement of any action (including,
                  without limitation, any governmental action), such Indemnitee,
                  if a claim in respect thereof shall be made against any
                  indemnifying party under this Section 4(f), shall deliver to
                  the indemnifying party a written notice of the commencement
                  thereof, and the indemnifying party shall be entitled to
                  participate therein, and, to the extent it shall desire, to
                  assume the defense thereof, with counsel mutually satisfactory
                  to the Indemnitee, after which the indemnifying person shall
                  not be liable to such Indemnitee for any legal expenses
                  subsequently incurred by such Indemnitee in connection with
                  the defense thereof; provided, however, that an Indemnitee
                  shall have the right to retain its own counsel, with fees and
                  expenses to be paid by the indemnifying party, if the
                  indemnifying party shall have failed to assume the defense of
                  any such action or if, in the reasonable opinion of counsel
                  retained by the indemnifying party, representation of such
                  Indemnitee by the counsel retained would be inappropriate due
                  to actual or potential differing interests between such
                  Indemnitee and any other party represented by such counsel in
                  such action. No indemnifying person shall be responsible for
                  paying the fees and expenses of more than one separate counsel
                  for all Indemnitees. Failure to deliver written notice to the
                  indemnifying party within a reasonable time of the
                  commencement of any action, if the indemnifying party shall be
                  materially prejudiced thereby, shall relieve such indemnifying
                  party of liability, but only to the extent that such
                  indemnifying party shall be prejudiced with respect to a
                  specific claim. An indemnifying party shall not, without the
                  prior written consent of the Indemnitee, settle or compromise
                  or consent to the entry of a judgment in any pending or
                  threatened claim,


<PAGE>


                  action, suit or proceeding in respect of which indemnification
                  may be sought hereunder unless such settlement, compromise or
                  consent shall include an unconditional release of such
                  Indemnitee from all liability arising out of such claim,
                  action, suit or proceeding.

                           (iv) If the indemnification provided for in Sections
                  4(f)(i) or 4(f)(ii) hereof shall be held by a court of
                  competent jurisdiction to be unavailable to an Indemnitee in
                  respect of any liability under the Securities Act, then, and
                  in each such case, the indemnifying party, in lieu of
                  indemnifying such Indemnitee hereunder, shall to the extent
                  permitted by applicable law contribute to the amount paid or
                  payable by such Indemnitee as a result of such loss,
                  liability, claim, damage or expense in such proportion as
                  shall be appropriate to reflect the relative fault of the
                  indemnifying party on the one hand and of the Indemnitee on
                  the other in connection with the Violation that resulted in
                  such loss, liability, claim, damage or expense as well as any
                  other relevant equitable considerations. The relative fault of
                  the indemnifying party and of the Indemnitee shall be
                  determined by a court of law by reference to, among other
                  things, whether the untrue or alleged untrue statement of a
                  material fact or the omission or alleged omission to state a
                  material fact shall have related to information supplied by
                  the indemnifying party or by the Indemnitee and the parties'
                  relative intent, knowledge, access to information and
                  opportunity to correct or prevent such statement, alleged
                  statement, omission or alleged omission; provided, that, in no
                  event, shall any contribution under this Section 4(f)(iv) by
                  any Holder exceed the proceeds (net of discounts or
                  commissions) from the offering received by such Holder. No
                  person or entity guilty of fraudulent misrepresentation
                  (within the meaning of Section 11 of the Securities Act) shall
                  be entitled to contribution from any person or entity who
                  shall not have been guilty of such fraudulent
                  misrepresentation.

                  (g) Rule 144 Reporting. With a view to making available the
         benefits of certain rules and regulations of the SEC which may at any
         time permit the sale of the Registrable Securities to the public
         without registration, while a public market shall exist for the Common
         Stock of the Company, the Company shall:

                           (i) Make and keep public information available, as
                  those terms are understood and defined in Rule 144,


<PAGE>


                  at all times while the Company shall be reporting under the
                  Exchange Act;

                           (ii) Use its best efforts to file with the SEC in a
                  timely manner all reports and other documents required of the
                  Company under the Securities Act and the Exchange Act; and

                           (iii) So long as a Holder shall own any Registrable
                  Securities, furnish to the Holder forthwith upon request a
                  written statement by the Company as to its compliance with the
                  reporting requirements of Rule 144, the Securities Act and the
                  Exchange Act, a copy of the most recent annual or quarterly
                  report of the Company and such other reports and documents of
                  the Company as a Holder may reasonably request in availing
                  itself of any rule or regulation of the SEC allowing a Holder
                  to sell any such Securities without registration.

                           (h) Default Shares.

                           (i) In the event that the registration statement
                  required to be filed pursuant to Section 4(b) relating to the
                  Shares and the Warrant Shares underlying the Warrants
                  delivered at the First Closing shall not be declared effective
                  by the SEC within 90 days from the date of the First Closing,
                  the Company shall issue and deliver, free of charge and
                  without cost, to the Purchasers (i) within 10 days of such
                  ninetieth day, certificates representing a number of fully
                  paid, non-assessable shares of Common Stock equal to the
                  aggregate of 2% of the Shares and the Warrant Shares issued or
                  issuable with respect to the First Closing (with additional
                  shares issued pursuant to this Section 4(h) referred to as
                  "DEFAULT SHARES") and (ii) within 10 days of the last date of
                  each additional 30-day period in which such registration
                  statement shall not have been declared effective by the SEC,
                  additional certificates representing a number of fully paid,
                  non-assessable shares of Common Stock equal to the aggregate
                  of 2% of such Shares and Warrant Shares and any issued Default
                  Shares;

                           (ii) In the event that the registration statement
                  required to be filed pursuant to Section 4(b) relating to the
                  Shares and the Warrant Shares underlying the Warrants
                  delivered at the Second Closing shall not be declared
                  effective by the SEC within 90 days from the date of the
                  Second Closing, the Company shall issue and deliver, free of
                  charge and without cost, to the Purchasers (i) within 10 days
                  of such ninetieth day, certificates representing a number of
                  fully paid, non-


<PAGE>


                  assessable shares of Common Stock equal to the aggregate of 2%
                  of the Shares and the Warrant Shares issued or issuable with
                  respect to the Second Closing and (ii) within 10 days of the
                  last date of each additional 30-day period in which such
                  registration statement shall not have been declared effective
                  by the SEC, additional certificates representing a number of
                  fully paid, non-assessable shares of Common Stock equal to the
                  aggregate of 2% of such Shares and Warrant Shares and any
                  issued Default Shares. The obligation of the Company to issue
                  shares of Common Stock under this Section 4(h)(ii) is separate

         Agreement or the terms of the Warrants, as the case may be, in a
         private transaction exempt from registration under the Securities Act.

         in such a private transaction, other than an affiliate of the

         such Securities, to agree in writing to be bound by all the terms and
         conditions of this Agreement. A Purchaser may not assign its rights
         under this Agreement in connection with the sale of Shares or Warrant
         Shares

                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                             LIFERATE SYSTEMS, INC.

                         ------------------------------


                  FOR VALUE RECEIVED,__________________________________
_______________, or assigns (the "HOLDER"), is entitled to purchase, subject to
the provisions of this Warrant, from LifeRate Systems, Inc., a Minnesota
corporation (the "COMPANY"), up to shares of Common Stock, without par value, of
the Company (the "COMMON STOCK") at any time or from time to time during the
period commencing on the date hereof through and including the tenth anniversary
of the date hereof (the "TERMINATION DATE"), at a price per share equal to $1.50
(the "EXERCISE PRICE"). The number of shares of Common Stock to be received upon
the exercise of this Warrant and the Exercise Price may be adjusted from time to
time as hereinafter set forth. The shares of Common Stock deliverable upon any
exercise of this Warrant are hereinafter sometimes referred to as "WARRANT
SHARES". This Warrant is issued by the Company pursuant to the Securities
Purchase Agreement dated November __, 1997 (the "PURCHASE AGREEMENT") among the
Company and each of the purchasers named on the signature pages thereto and
shall be 


<PAGE>


entitled to the rights set forth therein, including certain registration rights
relating to the Warrant Shares.

                  (a) EXERCISE OF WARRANT. This Warrant may be exercised in
whole or in part at any time or from time to time until the Termination Date;
provided, however, that if the date of exercise shall be a day on which banking
institutions in the State of New York shall be authorized by law to close, then
the Warrant shall be exercisable on the next succeeding day which shall not be
such a day. This Warrant may be exercised by presentation and surrender hereof
to the Company at its principal office, or at the office of its stock transfer
agent, if any, with the Purchase Form annexed hereto duly executed and
accompanied by payment of the Exercise Price for the number of Warrant Shares
specified in such Form. As soon as practicable after each such exercise, but not
later than two (2) days following the date of such exercise, the Company shall
issue and deliver to the Holder a certificate or certificates for the Warrant
Shares issuable upon such exercise, registered in the name of the Holder or its
designee(s). If this Warrant shall be exercised in part, the Company shall, upon
surrender of the Warrant for cancellation, execute and deliver a new Warrant
evidencing the rights of the Holder thereof to purchase the balance of the
Warrant Shares purchasable hereunder. Upon receipt by the Company of the Warrant
at its office, or by the stock transfer agent of the Company at its office, in
proper form for exercise and accompanied by proper payment, the Holder shall be
deemed to be the holder of record of the Warrant Shares issuable upon such
exercise, notwithstanding that the stock transfer books of the Company shall
then be closed or that certificates representing such shares of Common Stock
shall not then have been physically delivered to the Holder.

                  (b) RESERVATION OF SHARES. The Company covenants and agrees
that it shall at all times reserve for issuance and delivery upon exercise of
the Warrant such number of shares of Common Stock as shall be required for
issuance and delivery upon exercise of the Warrant. In addition, the Company
further covenants and agrees that all Warrant Shares, upon issuance, shall be
duly and validly issued, fully paid and non-assessable and no personal liability
shall attach to the holder thereof.

                  (c) FRACTIONAL SHARES. No fractional shares of Common Stock
shall be issued upon exercise of this Warrant. All fractional shares shall be
eliminated by rounding any fraction to the nearest whole number of shares of
Common Stock.


<PAGE>


                  (d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This
Warrant shall be exchangeable, without expense, at the option of the Holder,
upon presentation and surrender hereof to the Company, or at the office of its
stock transfer agent, for other Warrants of different denominations entitling
the Holder thereof to purchase in the aggregate the same number of shares of
Common Stock purchasable hereunder. Upon surrender of this Warrant to the
Company or the office of its stock transfer agent, with the Assignment Form
annexed hereto duly executed and funds sufficient to pay any transfer tax, the
Company, without charge, shall execute and deliver new Warrants in the name of
the assignee named in such instrument of assignment and this Warrant shall be
cancelled promptly, provided that the Company shall receive from the Holder an
opinion of counsel that such assignment, as contemplated by the Holder, shall
not violate applicable Federal or state securities laws. This Warrant may be
divided or combined with other Warrants which carry the same rights upon
presentation hereof at the principal office of the Company or the office of its
stock transfer agent, together with a written notice, signed by the Holder
hereof, specifying the names and denominations in which new Warrants are to be
issued. The term "WARRANTS" as used herein shall include any warrants into which
this Warrant may be divided or exchanged. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company shall execute and deliver a new Warrant of
like tenor and date.

                  (e) RIGHTS OF HOLDER. The Holder shall not, until exercise
hereof, be entitled to any rights of a stockholder in the Company, either at law
or equity, and the rights of the Holder shall be limited to those expressed
herein.

                  (f) ANTI-DILUTION PROVISIONS. The Exercise Price in effect at
any time and the number and kind of securities purchasable upon the exercise of
this Warrant shall be subject to adjustment from time to time upon the happening
of any of the following events:

                  (i) In the event that the Company shall issue or sell any
         shares of Common Stock (except as provided in paragraph (f)(v) hereof)
         for a consideration per share less than the greater of (A) the Exercise
         Price in effect immediately prior to such issue or sale and (B) the
         Market Price (as defined in paragraph (f)(ii)(G) hereof) on the date of
         such issue or sale,


<PAGE>


         then the Exercise Price, as of the date of such issue or sale, shall be
         reduced to such lesser price (calculated to the nearest cent) as shall
         be determined by multiplying the Exercise Price in effect immediately
         prior thereto by a fraction, the numerator of which shall be the sum of
         (x) the number of shares of Common Stock outstanding immediately prior
         to the issuance or sale of such additional shares and (y) the number of
         shares of Common Stock which the aggregate consideration received for
         the issuance or sale of such additional shares would purchase at the
         greater of the Market Price on the date of such issue or sale or the
         Exercise Price then in effect, and the denominator of which shall be
         the number of shares of Common Stock outstanding immediately after the
         issuance or sale of such additional shares.

                  (ii) For the purposes of paragraph (f)(i) above, the following
         subparagraphs (A) to (G), inclusive, shall be applicable:

                           (A) If at any time the Company shall issue or sell
                  any rights to subscribe for, or any rights or options to
                  purchase, Common Stock or any stock or other securities
                  convertible into or exchangeable for Common Stock (such
                  convertible or exchangeable stock or securities being
                  hereinafter called "CONVERTIBLE SECURITIES"), whether or not
                  such rights or options or the right to convert or exchange any
                  such Convertible Securities shall be immediately exercisable,
                  and the price per share for which Common Stock shall be
                  issuable upon the exercise of such rights or options or upon
                  conversion or exchange of such Convertible Securities
                  (determined by dividing (1) the total amount, if any, received
                  or receivable by the Company as consideration for the granting
                  of such rights or options, plus the minimum aggregate amount
                  of additional consideration payable to the Company upon the
                  exercise of such rights or options, plus, in the case of any
                  such rights or options which shall relate to Convertible
                  Securities, the minimum aggregate amount of additional
                  consideration, if any, payable upon the issue or sale of such
                  Convertible Securities and upon the conversion or exchange
                  thereof, by (2) the total number of shares of Common Stock
                  issuable upon the exercise of such rights or options or upon
                  the conversion or exchange of all such Convertible Securities
                  issuable upon the exercise of such rights or options) shall be
                  less than the greater of (x) the Exercise Price in effect
                  immediately prior to the time of the issue 


<PAGE>


                  or sale of such rights or options and (y) the Market Price on
                  the date of such issue or sale, then the total number of
                  shares of Common Stock issuable upon the exercise of such
                  rights or options or upon conversion or exchange of the total
                  amount of such Convertible Securities issuable upon the
                  exercise of such rights or options shall (as of the date of
                  granting of such rights or options) be deemed to be
                  outstanding and to have been issued for such price per share,
                  and except as provided in paragraph (f)(iv), no further
                  adjustments of the Exercise Price shall be made upon the
                  actual issue of such Common Stock or of such Convertible
                  Securities, upon the exercise of such rights or options or
                  upon the actual issue of such Common Stock upon conversion or
                  exchange of such Convertible Securities.

                           (B) If at any time the Company shall issue or sell
                  any Convertible Securities, whether or not the rights to
                  exchange or convert thereunder shall be immediately
                  exercisable, and the price per share for which Common Stock
                  shall be issuable upon such conversion or exchange (determined
                  by dividing (1) the total amount received or receivable by the
                  Company as consideration for the issue or sale of such
                  Convertible Securities, plus the minimum aggregate amount of
                  additional consideration, if any, payable to the Company upon
                  the conversion or exchange thereof, by (2) the total number of
                  shares of Common Stock issuable upon the conversion or
                  exchange of all such Convertible Securities) shall be less
                  than the greater of (x) the Exercise Price in effect
                  immediately prior to the time of such issue or sale and (y)
                  the Market Price on the date of such issue or sale, then the
                  total number of shares of Common Stock issuable upon
                  conversion or exchange of all such Convertible Securities
                  shall (as of the date of the issue or sale of such Convertible
                  Securities) be deemed to be outstanding and to have been
                  issued for such price per share, and, except as provided in
                  paragraph (f)(iv) no further adjustments of the Exercise Price
                  shall be made upon the actual issue of such Common Stock upon
                  conversion or exchange of such Convertible Securities. In
                  addition, if any issue or sale of such Convertible Securities
                  shall be made upon exercise of any rights to subscribe for or
                  to purchase or any option to purchase any such Convertible
                  Securities for which adjustments of the Exercise Price shall
                  have been or shall be 


<PAGE>


                  made pursuant to other provisions of this paragraph (f)(ii),
                  no further adjustment of the Exercise Price shall be made by
                  reason of such issue or sale.

                           (C) If at any time the Company shall declare and pay
                  a dividend or make any other distribution upon the Common
                  Stock payable in Common Stock or Convertible Securities, any
                  such Common Stock or Convertible Securities, as the case may
                  be, issuable in payment of such dividend or distribution shall
                  be deemed to have been issued or sold without consideration.

                           (D) If at any time any shares of Common Stock or
                  Convertible Securities or any rights or options to purchase
                  any such Common Stock or Convertible Securities shall be
                  issued or sold for cash, the consideration received therefor
                  shall be deemed to be the amount received by the Company
                  therefor, without deduction therefrom of any expenses incurred
                  or any underwriting commissions or concessions or discounts
                  paid or allowed by the Company in connection therewith. In
                  case any shares of Common Stock or Convertible Securities or
                  any rights or options to purchase any such Common Stock or
                  Convertible Securities shall be issued or sold for a
                  consideration other than cash, the amount of the consideration
                  other than cash received by the Company shall be deemed to be
                  the fair value of such consideration as determined by the
                  Board of Directors, without deduction therefrom of any
                  expenses incurred or any underwriting commissions or
                  concessions or discounts paid or allowed by the Company in
                  connection therewith. In case any shares of Common Stock or
                  Convertible Securities or any rights or options to purchase
                  any such Common Stock or Convertible Securities shall be
                  issued in connection with any merger of another corporation
                  into the Company, the amount of consideration therefor shall
                  be deemed to be the fair value of such merged corporation as
                  determined by the Board of Directors reduced by all cash and
                  other consideration (if any) paid by the Company in connection
                  with such merger.

                           (E) If at any time the Company shall take a record of
                  the holders of Common Stock for the purpose of entitling them
                  (1) to receive a dividend or other distribution payable in
                  Common Stock or in Convertible Securities, or (2) to 


<PAGE>


                  subscribe for or purchase Common Stock or Convertible
                  Securities, then such record date shall be deemed to be the
                  date of the issue or sale of the shares of Common Stock deemed
                  to have been issued or sold upon the declaration of such
                  dividend or the making of such other distribution or the date
                  of the granting of such right of subscription or purchase, as
                  the case may be.

                           (F) The number of shares of Common Stock outstanding
                  at any given time shall not include shares owned or held by or
                  for the account of the Company, provided that such shares are
                  neither issued, sold or otherwise distributed by the Company.

                           (G) For purposes hereof, the "MARKET PRICE" shall
                  mean the closing bid price of the Common Stock in the
                  over-the-counter market, or, if the Common Stock shall be
                  quoted on The Nasdaq National Market or The Nasdaq SmallCap
                  Market or listed on a national securities exchange, on such
                  principal market or exchange on which the Common Stock may be
                  listed, in each case on the day prior to the date of
                  determination of such "Market Price". If at any time the
                  Common Stock shall not be traded in the over-the-counter
                  market or quoted or listed on The Nasdaq National Market or
                  The Nasdaq SmallCap Market or a national securities exchange,
                  the "Market Price" of a share of Common Stock shall be deemed
                  to be the higher of (x) the book value thereof (as determined
                  by any firm of independent public accountants of nationally
                  recognized standing selected by the Board of Directors) as of
                  the last day of any month ending within 60 days preceding the
                  date of determination, or (y) the fair value thereof (as
                  determined in good faith by the Board of Directors) as of a
                  date which shall be within 15 days of the date of
                  determination.

                  (iii) In case at any time the Company shall subdivide its
         outstanding shares of Common Stock into a greater number of shares, the
         Exercise Price in effect immediately prior to such subdivision shall be
         proportionately reduced. In case at any time the outstanding shares of
         Common Stock of the Company shall be combined into a smaller number of
         shares, the Exercise Price in effect immediately prior to such
         combination shall be proportionately increased.


<PAGE>


                  (iv) If the purchase or exercise price provided for in any
         right or option referred to in paragraph (f)(ii)(A), or the rate at
         which any Convertible Securities referred to in paragraph (f)(ii)(A) or
         (B) shall be convertible into or exchangeable for Common Stock, shall
         change or a different purchase or exercise price or rate shall become
         effective at any time or from time to time, then, upon such change
         becoming effective, the Exercise Price then in effect hereunder shall
         forthwith be increased or decreased to such Exercise Price as would
         have been in effect had the adjustments made upon the granting or
         issuance of such rights or options or Convertible Securities been made
         upon the basis of (A) the issuance of the number of shares of Common
         Stock theretofore actually delivered upon the exercise of such options
         or rights or upon the conversion or exchange of such Convertible
         Securities consideration received therefor and (B) the granting or
         issuance at the time of such change of any such options, rights or
         Convertible Securities then still outstanding for the consideration, if
         any, received by the Company therefor and to be received on the basis
         of such changed price.

                   (v) The Company shall not be required to make any adjustment
         to the Exercise Price in the case of:

                           (A) the granting, after the date hereof, by the
                  Company of stock options or stock awards with respect to
                  shares of Common Stock currently reserved for issuance under
                  the Company's 1993 Stock Option Plan, as amended, and Employee
                  Stock Purchase Plan, as amended;

                           (B) the issuance of shares of Common Stock pursuant
                  to the exercise of the options referred to in paragraph
                  (f)(v)(A) above or any other options outstanding as of the
                  date hereof;

                           (C) the issuance of shares of Common Stock pursuant
                  to the exercise of any warrants outstanding on the date
                  hereof; and

                           (D) the issuance of shares of Common Stock upon the
                  exercise of any of the Warrants.

                  (vi) Whenever the Exercise Price payable upon exercise of this
         Warrant shall be adjusted pursuant to this paragraph (f), the number of
         Warrant Shares purchasable upon exercise hereof simultaneously shall be
         adjusted by multiplying the number of Warrant Shares issuable
         immediately prior to such adjustment by the 


<PAGE>


         Exercise Price in effect immediately prior to such adjustment and
         dividing the product so obtained by the Exercise Price, as adjusted.

                  (g) OFFICER'S CERTIFICATE. The Company shall give notice to
each record holder of the Warrants of any event or transaction that shall result
in an adjustment in the Exercise Price, within five business days thereof, at
such Holder's address as the same appears on the books of the Company, including
a computation of such adjustment and any adjustment in the number of Warrant
Shares for which such Holder may exercise such Holder's Warrant and any further
information as shall be necessary to confirm the computation of such
adjustments.

                  (h) CERTAIN NOTICES TO HOLDERS. So long as this Warrant shall
be outstanding, if (i) the Company shall pay any dividend or make any
distribution upon the Common Stock, (ii) the Company shall offer to the holders
of the Common Stock for subscription or purchase by them any share of any class
of capital stock or any other rights or (iii) any capital reorganization of the
Company, reclassification of the capital stock of the Company, consolidation,
merger or other business combination of the Company with or into another
corporation, sale, lease or transfer of all or substantially all of the assets
of the Company to another corporation, or voluntary or involuntary dissolution,
liquidation or winding up of the Company shall be effected, then in any such
case, the Company shall cause to be mailed by certified mail to the Holder, at
least 30 days prior to the date specified in (x) or (y) below, as the case may
be, a notice containing a brief description of the proposed action and stating
the date on which (x) a record date shall be established for the purpose of such
dividend, distribution or rights offering or (y) such reclassification,
reorganization, consolidation, merger, conveyance, sale, lease, transfer,
dissolution, liquidation or winding up shall take place and the date, if any to
be fixed, as of which the holders of Common Stock or other securities shall
receive cash or other property deliverable upon such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation or
winding up.

                  (i) RECLASSIFICATION, REORGANIZATION, MERGER OR OTHER BUSINESS
COMBINATION. In case of any reclassification, capital reorganization or other
change of outstanding shares of Common Stock, or in case of any consolidation,
merger or other business combination of the Company with or into another
corporation or other entity (other than a merger with a subsidiary in which
merger the Company shall be the continuing corporation and which shall not
result in any reclassification, capital reorganization 


<PAGE>


or other change of outstanding shares of Common Stock of the class issuable upon
exercise of this Warrant) or in case of any sale, lease or conveyance to another
corporation or other entity of all or substantially all of the assets of the
Company, the Company shall cause effective provisions to be made so that the
Holder, by exercising this Warrant at any time after the consummation of such
reclassification, change, consolidation, merger, sale or conveyance, shall be
entitled to receive the stock or other securities or property to which such
Holder would have been entitled upon such consummation if such Holder had
exercised this Warrant immediately prior to such consummation. Any such
provision shall include provisions for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Warrant. The foregoing provisions of this paragraph (i) shall similarly apply to
successive reclassifications, capital reorganizations and changes of shares of
Common Stock and to successive consolidations, mergers, sales or conveyances. In
the event that, in connection with any such capital reorganization or
reclassification, consolidation, merger, sale or conveyance, additional shares
of Common Stock shall be issued in exchange, conversion, substitution or
payment, in whole or in part, for a security of the Company other than Common
Stock, any such issue shall be treated as an issue of Common Stock subject to
the provisions of paragraph (f) hereof.

                  (j) BUY-IN RIGHTS. In the event that (i)(A) the Company shall
fail for any reason to deliver shares of Common Stock to a Holder upon any
exercise of this Warrant within the time period specified in paragraph (a)
hereof, or (B) the Company shall fail to remove any restrictive legend on any
certificates evidencing such shares of Common Stock as and when required under
Section 5(i) of the Purchase Agreement and (ii) thereafter, such Holder shall
purchase (in an open market transaction or otherwise) shares of Common Stock to
make delivery in satisfaction of a sale by such Holder of (A) the shares of
Common Stock which such Holder anticipated receiving upon such exercise, or (B)
such unlegended shares of Common Stock, as the case may be (in each case, the
"SOLD SHARES"), then the Company shall pay to such Holder (in addition to any
other remedies available to the Holder) the amount by which (x) such Holder's
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased shall exceed (y) the net proceeds received by such
Holder from the sale of the Sold Shares. The Company shall make any payments
required pursuant to this paragraph (j) within five business days after receipt
of written notice from the Holder setting forth the calculation of the amount
due hereunder.


<PAGE>


                  (k) GOVERNING LAW. This Warrant shall be governed by and
construed in accordance with the law of the State of New York.

                  (l) NOTICES. Any notice required to be given or delivered to
the Company under the terms of this Warrant shall be in writing and addressed to
the Chief Executive Officer of the Company at its principal corporate offices.
Any notice required to be given or delivered to the Holder shall be in writing
and addressed to the Holder at the address indicated in the Purchase Agreement

by certified or registered mail (return receipt requested); one (1) business day
after deposit with any nationally recognized overnight courier (prepaid); or one
(1) business day after transmission by facsimile and receipt by the sender of
written facsimile confirmation.

APF, LLC
c/o Anthony P. Furnary, M.D.
7266 S.W. Eaton Court
Portland, OR 97225-6045

Dear Dr. Furnary:

Reference is made to (i) the Modification Agreement dated as of March 25, 1997
(the "Modification Agreement") by and among LifeRate Systems, Inc. (the
"Company") and you relating to the amendment of certain terms set forth in the
Prior Agreement (as such term is defined in the Modification Agreement); (ii)
the Consulting Agreement dated as of March 25, 1997 between you and the Company
(the "Consulting Agreement "); (iii) a Non-Statutory Stock Option Agreement,
dated March 4, 1997 (the "Option Agreement"), covering options to purchase
550,000 shares of common stock, no par value ("Common Stock"); (iv) two
Non-Statutory Stock Option Agreements, each dated March 4, 1997 (the "Other
Option Agreements"), covering options to purchase an aggregate of 36,333 shares
of Common Stock and (v) the Master Agreement dated as of March 25, 1997 between
the Company, APF, LLC ("APF) and Dr. Furnary. As we have discussed, the
investors in our impending private placement offering of approximately 9,000,000
shares of Common Stock (the "Shares") at $.50 per share and approximately
9,000,000 warrants (the "Warrants") to purchase shares of Common Stock (the "New
Financing") are requiring, as a condition to closing that offering, that we
obtain certain agreements from some of our major creditors.

Accordingly, notwithstanding anything in the Consulting Agreement, the
Modification Agreement, the Prior Agreement, the Option Agreement, the Other
Option Agreements or the Master Agreement to the contrary, we hereby request
that you agree to the following modifications and amendments to the Consulting
Agreement, the Modification Agreement, the Prior Agreement, the Option
Agreement, the Other Option Agreements and the Master Agreement, which
modifications and agreements are to become effective upon, and are subject to


<PAGE>


the consummation of, the first closing of the New Financing, which closing will
relate to approximately 2,500,000 Shares and approximately 2,500,000 Warrants
(the "First Closing"), on or before November 21, 1997:

         (i) Consulting Agreement. The Consulting Agreement is hereby terminated
         in its entirety effective as of the First Closing, and all rights,
         obligations and amounts owing or to become due and payable in the
         future by either party thereunder are extinguished and deemed
         satisfied.

         (ii) Modification Agreement and Prior Agreement. All "milestone royalty
         payments" payable by the Company under Section 6.2 of the Modification
         Agreement, in the aggregate amount of $450,000, shall be terminated and
         extinguished effective as of the First Closing.

         (iii) Option Agreements. The Option Agreement is revised, effective as
         of the First Closing, as follows: (x) the number of shares covered
         thereby is reduced from 550,000 shares to 200,000 shares and (y) the
         "Option Exercise Price" is changed to $1.00 per share (as so modified,
         the "Amended Option Agreement"). In addition, Dr. Furnary and APF agree
         not to sell or otherwise transfer any shares of Common Stock, purchased
         upon exercise of the Amended Option Agreement or the Other Option
         Agreements, before January 1, 2000.

in our impending private placement offering of approximately 9,000,000 shares of
Common Stock (the "Shares") at $.50 per share and approximately 9,000,000
warrants (the "Warrants") to purchase shares of Common Stock (the "New
Financing") are requiring, as a condition to closing that offering, that we
obtain certain agreements from some of our major creditors.

 Accordingly, notwithstanding anything in the Existing Agreements to the
contrary, we hereby request that you agree to the following modifications and
amendments to Existing Agreements, which modifications and agreements are to
become effective upon, and are subject to the consummation of, the first closing
of the New Financing, which closing will relate to approximately 2,500,000
Shares and approximately 2,500,000 Warrants (the "First Closing"), on or before
November 21, 1997:

         (i) Interest and Principal. The Company's obligation (x) to accrue or
         pay any interest now or hereafter owing to Medtronic in respect of the
         Note shall be eliminated and canceled and (y) to pay principal to
         Medtronic in respect of the Note is deferred, without interest, until
         May 12, 2002; provided however, that this agreement to defer principal

         shall immediately terminate in the event a voluntary or involuntary
         petition is filed in respect of the Company under the federal
         bankruptcy laws or in the event there occurs any other Event of Default
         under Section 4(c), (d), (e), (f), (g) or (h) of the Note; and,
         provided further, that, with respect to such Section 4(c), the Company
         shall have 60 days to cure the event specified in Section 4(c) before
         it shall constitute an Event of Default.

         (ii) Modification to Conversion Price. The "Conversion Price" as set
         forth in Section 2 of the Note is amended in its entirety to read as
         follows:

         (iii) No Additional Warrants. The Company's obligation to issue the
         additional warrants referred to in Section 7 (a) and (b) of the Note is
         hereby terminated and extinguished.

         (iv) Modification to Exercise Price. The "Exercise Price" of the
         Medtronic Warrant (as defined therein) is repriced at $0.50 per share
         of Common Stock.

         (v) No Anti-Dilution Adjustments. There shall be no further adjustment
         to the Exercise Price of the Medtronic Warrant or the Conversion Price
         of the Note, nor shall there by any other anti-dilution adjustment in
         the number of shares purchasable under the Medtronic Warrant or
         convertible under the Note, resulting from (x) the issuance of the
         Shares, the Warrants, shares of Common Stock underlying the Warrants
         and any Default Shares (as defined in the Securities Purchase Agreement
         pursuant to which the Shares shall be sold), (y) any and all
         conversions of existing debt of the Company into shares of Common Stock
         in connection with the New Financing and (z) any and all other
         transactions, including without limitation, issuances of options or
         warrants, or adjustments to the exercise prices of existing options,
         warrants or convertible notes, that are being made in connection with
         the New Financing as set forth on Schedule 6(j) to the Securities
         Purchase Agreement (a copy of which Schedule is attached hereto). .

         (vi) Waiver of Rights of First Refusal; Termination of Right of First
         Refusal Regarding Sale of Company. Medtronic hereby (x) waives, solely
         for purposes of the New Financing, its rights of first refusal under
         Section 3.1 of the Investment Agreement to purchase any Shares or
         Warrants in the New Financing and (y) terminates and permanently waives
         all of its rights of first refusal on the sale of the Company as set
         forth in Section 3.2 of the Investment Agreement; provided, however,
         that Medtronic shall have its rights of first refusal as set forth in
         Section 3.2 of the Investment Agreement restored in the event that, in
         the twelve months prior to a Company Sale (as defined in such Section
         3.2), 50% or more of the license revenue of the Company generated from
         LifeRate products sold for cardiovascular applications is directly
         generated as a result of referrals originating from the Medtronic
         cardiovascular sales organization.

         (vii) Registration Rights. Medtronic hereby (x) consents to the grant
         of registration rights to investors in the New Financing, to holders of
         convertible promissory notes that are converted into shares of Common
         Stock in connection with the New Financing (which 


<PAGE>


         holders were granted registration rights prior to the date hereof) and
         to holders of the Company's convertible promissory notes dated July 21,
         1997 in the aggregate principal amount of $500,000 (which holders were
         granted registration rights prior to the date hereof) and waives the
         restrictions contained in Section 8.4 of the Investment Agreement with
         respect thereto, (y) agrees not to exercise, and otherwise waives, any
         of its registration rights under Article 8 of the Investment Agreement
         prior to January 1, 2000 and (z) agrees that Section 8.2(b) of the
         Investment Agreement is deemed amended to the extent necessary to
         provide that any reduction in the number of securities to be included
         in a registration statement shall be made pro rata among Medtronic,
         other holders of securities of the Company having registration rights
         granted prior to the date of the Investment Agreement and holders of
         Registrable Securities, as defined in the Securities Purchase Agreement
         pursuant to which the Shares are to be sold.

         (viii) Assignment. This letter agreement shall be binding upon and
         inure to the benefit of the successors and assigns of Medtronic and no
         transfer of the Note, the Medtronic Warrant, or the shares of Common
         Stock issuable upon conversion of the Note or exercise of the Medtronic
         Warrant shall be made unless the transferee shall agree in writing to
         be bound by the terms and conditions hereof.

         (ix) Replacement of Note and Medtronic Warrant. Upon notice from the
         Company, Medtronic shall promptly submit the Note and the Medtronic

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is effective as of August 18, 1997 between LIFERATE
SYSTEMS, INC., a Minnesota corporation ("the Company"), and David J. Chinsky
(the "Employee")i.

herein, the Company and the Employee, each intending to be legally bound, agree
as follows:

Agreement, the Company agrees to employ the Employee as the Chief Executive
Officer and President of the Company, and the Employee accepts this employment.

commence on August 26, 1997 and will be for a period of one year subject to
earlier termination pursuant to Section 4. The Employee shall receive a
performance review at the end of the first year of employment and annually
thereafter. Subject to such review(s), this Agreement will be extended for a
one-year period. If the review does not take place, or does not take place
before the end of this term, this Agreement will be automatically renewed for
one (1) year subject to the provisions of Section 4 herein.

         4) Termination. Subject to the respective continuing obligations of the
Company and the Employee under Sections 8, 9, 10 and 11 hereof:

         (a) This Agreement may be terminated by the Company on 10 days' written
         notice to the Employee "for cause," with the basis for termination
         specified in such notice. For purposes of this Agreement, "for cause"
         will mean (i) any unlawful or criminal activity of a serious nature; or
         (ii) if not corrected within 60 days after written notice thereof, any
         willful breach of duty, habitual neglect of duty or inadequate job
         performance as


<PAGE>


         determined solely by the Board of Directors at LifeRate; or (iii) a
         material breach of any provision of this Agreement.

         (b) This Agreement may be terminated upon the Employee's death or Total

         parties.

         (e) This Agreement may be terminated by Employee upon 30 days written
         notice to the Company.

         (f) This Agreement may be terminated by the Company upon 30 days
         written notice to Employee subject to the post-termination obligations
         set forth in Section 7(b) herein.

         5) Compensation.

         (a) Base Salary. In consideration of the Employee's services under this
         Agreement, the Company agrees to pay the Employee an annual base salary
         (the "Base Salary"). The Base Salary will be set at $225,000. The Base
         Salary will be payable in accordance with the standard payroll
         practices of the Company.

         (b) Stock Options. Upon the execution of this Agreement and
         commencement of employment, the Employee will receive a stock option
         (the "Option") to purchase 200,000 shares of the Company's common
         stock, no par value (the "Common Stock"). The Option will have an
         exercise price equal to the closing bid price of the Common Stock on
         the date hereof (the "Exercise Price") representing the fair market
         value of the Common Stock on the date of acceptance of employment. In
         addition to the Option referred to above, if Employee is still employed
         after one (1) year, and subject to reasonable performance criteria
         regarding Company performance to be set by the Company and the Employee
         being met, the Employee will be eligible for additional stock options
         of 100,000 shares. The exercise price for all of these options shall be
         the fair market value of the Common Stock on the date of acceptance of
         employment. All of the above-referenced stock options will vest over
         three years at the rate of one-third per year, with the vesting period
         to begin upon the commencement of employment. The options shall be
         exercisable for a period of five (5) years from the date each are
         vested after which time the options shall expire. If Employee's
         employment terminates for any reason, Employee forfeits all rights to
         unvested options as of the date of termination. If Employee's
         employment is terminated for any reason, Employee's vested options
         shall


<PAGE>


         remain exercisable by Employee for a period of 30 days after
         termination after which time such vested options will expire.

         It is anticipated that the Company will undergo a round of financing
         within the Employee's first year of employment which may result in more
         shares of the Company's Common Stock to be issued and sold. It is the
         intent of the parties to this Agreement that the Employee shall be able
         to maintain the percentage the Employee's options represents of the
         common shares outstanding at the time of grant and before the financing
         occurred. As to the first 200,000 stock options, the parties agree that
         the percentage would be 5.23%. If that percentage is reduced by the
         issuance of shares during the next round of financing, the Employee
         shall be awarded an additional number of options to maintain that
         percentage, subject to the same price, vesting, exercise and forfeiture
         provisions as set forth herein for the original options.

         If the Employee is awarded the additional 100,000 stock options
         referenced herein, the parties agree that Employee's percentage would
         be 7.84% If that percentage has been reduced by the issuance of shares
         during the round of financing in the first year, the Employee will be
         awarded an additional number of options to maintain that percentage,
         subject to the same price, vesting, exercise and forfeiture provisions
         as set forth herein for the original options.

         (c) Bonus. The Employee shall be eligible for a performance bonus of up
         to $100,000 annually if certain performance criteria, to be established
         by the Company, are met. The Company guarantees that Employee will be
         paid a first year bonus of $100,000, under the following conditions:

                  (1)      Employee remains an employee of the Company for the
                           full year;

                  (2)      Employee terminates his employment during the first
                           year pursuant to Section 4(c) herein; and

                  3)       Employee is disabled or dies within the first year
                           pursuant to Section 4(b) herein, subject to being
                           prorated as set forth in Section 7(c) herein.

         Employee will not receive the first year bonus if he terminates his
         employment pursuant to Section 4(e) or if his employment is terminated
         by the Company pursuant to Section 4(a) herein.

         (d) Bonus Buyout. The Employer agrees to pay to Employee, on or before
         February 15, 1998, the gross amount of $108,000 (representing the

         previous employment) under the following conditions:


<PAGE>


                  (1)      The Company receives the financing it currently
                           contemplates receiving by that time. If financing is
                           secured by not received by February 15, 1998, payment
                           will be made to Employee as soon as funds are
                           received; and

                  (2)      Employee is still employed by Employer and actively
                           working on February 15, 1998 or when funds are

          Company's standard benefit program, subject to change by the Company
          for all personnel, including the following: life insurance, medical
          insurance, 160 hours of personal time off, holidays, 401(k) plan, and
          an employee stock purchase plan.

          (f) Expenses. The Company will pay or reimburse the Employee for all
          reasonable expenses (including, without limitation, expenses for
          entertainment, travel, personal business education, meals, hotel
          accommodations)( that the Employee incurs while performing his duties
          under this Agreement, provided that the Employee accounts properly for
          such expenses to the Company in accordance with Company policies. The
          Company will pay temporary living expenses of $1,000 per month for a
          period of 24 months or until the Employee moves his residence to the

          period. The Company will pay reasonable commuting costs between the
          Twin Cities and Detroit for a period of two years.

          6)      Change in Control.

         (a) For purposes of this Agreement, a "Change in Control" of the
         Company will mean the following:

                  (1)      the sale, lease, exchange or other transfer, directly
                           or indirectly, of substantially all of the assets of
                           the Company ( in one transaction or in a series of
                           related transactions) to a period or entity that is
                           not controlled by the Company;

                  (2)      the approval by the shareholders of the Company of
                           any plan or proposal for the liquidation or
                           dissolution of the Company;

                  (3)      a merger or consolidation to which the Company is a
                           party if the shareholders of the Company immediately
                           prior to effective date of such merger or
                           consolidation have "beneficial ownership" (as defined
                           in Rule 13d-3 under the Securities Exchange Act of
                           1934, as amended (the "Exchange Act")), immediately
                           following the effective date of such merger or
                           consideration, of securities of the surviving
                           corporation representing (A) more than 50%, but not
                           more than 80%, of the combined voting power of the
                           surviving corporation's then outstanding securities
                           ordinarily having the right to vote at elections of
                           directors, unless such merger or consolidation has
                           been approved in advance by the Incumbent 


<PAGE>


                           Directors, or (B) 50% or less of the combined voting
                           power of the surviving corporation's then outstanding
                           securities ordinarily having the right to vote at
                           elections of directors (regardless of any approval by
                           the Incumbent Directors);

                  (4)      any person becomes after the effective date of this
                           Agreement the "beneficial owner" (as defined in Rule
                           13d-3 of the Exchange Act), directly or indirectly,
                           of (A) 20% or more, but not 50% or more, of the
                           combined voting power of the Company's outstanding
                           securities ordinarily having the right to vote at
                           elections of directors, unless the transaction
                           resulting in such ownership has been approved in
                           advance by the Incumbent Directors, or (B) 50% or
                           more of the combined voting power of the Company's
                           outstanding securities ordinarily having the right to
                           vote at elections of directors (regardless of any
                           approval by the Incumbent Directors);

                  (5)      the Incumbent Directors cease for any reason to
                           constitute at least a majority of the Board; or

                  (6)      a change in control of the Company of a nature that
                           would be required to be reported pursuant to Section
                           13 or 15(d) of the Exchange Act, whether or not the
                           Company is then subject to such reporting
                           requirements.

         (b) For purposes of this Section 6, the Incumbent Directors will mean
         any individual who is a member of the Board on the effective date of
         this Agreement and any individual who subsequently becomes a member of
         the Board whose election, or nomination for election by the Company's
         shareholders, was approved by a vote of at least a majority of the
         directors comprising the Board on the effective date of this Agreement
         (either by specific vote or by approval of the proxy statement of the
         Company in which such individual is named as a nominee for director
         without objection to such nomination).

         (c) Subject to the limitations of Section 7(e) hereof, if a Change in
         Control occurs, the Option will become immediately exercisable in full
         and will remain exercisable for the remainder of its term, regardless
         of whether the Employee remains in the employ or service of the
         Company.

         7) Payments Upon Termination.

         (a) If this Agreement is terminated by the Company pursuant to Section
         4(a) of this Agreement for cause, the Employee will be paid his Base
         Salary through the date of termination, and any unpaid expense
         reimbursement.

         (b) If this Agreement is terminated by the Company pursuant to Section
         4(f) of this Agreement, then the Employee will be paid, in addition to
         any unpaid expense reimbursement, one year of his Base Salary as
         severance. Also, normal company 


<PAGE>


         provided benefits will be continued for the one year period. Such
         severance payments are expressly conditioned upon the Employee meeting
         his post-termination obligations as set forth herein in Section 8, 9,
         10 and 12 of this Agreement. Payments will be made twice monthly over
         the year, but shall cease if the Employee breaches his obligations
         under Sections 8, 9 or 10 of this Agreement.

                  (c) If this Agreement is terminated pursuant to Section 4(b)
                  of this Agreement, the Employee will be paid (i) his Base
                  Salary through the end of the month following his death or
                  termination as a result of Total Disability, (ii) any bonus,
                  determined in accordance with Section 5(c) of this Agreement,
                  to which the Employee would have been entitled for the fiscal
                  year in which his death or termination for Total Disability
                  occurred, pro rated to the end of the month following his
                  death or termination for Total Disability, and (iii) any
                  unpaid expense reimbursement.

         (d) If this Agreement is terminated by the Employee, following a Change
         in Control, pursuant to Section 4(c) of this Agreement for Good Reason,
         the Employee (i) will continue to be paid his then current Base Salary,
         at the same times and in the same manner as prior to his termination,
         for the remainder of the then current term of this Agreement, provided
         that such payments will continue only so long as the Employee continues
         to comply with all of the terms and conditions of Section 8, 9 and 10
         of this Agreement; (ii) will be paid any bonus, determined in
         accordance with Section 5(c) of this Agreement, to which the Employee
         would have been entitled for the entire fiscal year in which he was
         terminated had his employment with the Company not been terminated; and
         (iii) will be paid any unpaid expense reimbursement.

         (e) For purposes of this Agreement, "Good Reason" will mean the good
         faith determination by the Employee, in his sole judgment, that any one
         or more of the following events has occurred, without the Employee's
         written consent, following a Change in Control:

                  (1)      an adverse change in the Employee's status or
                           position as an executive of the Company as in effect
                           immediately prior to the Change in Control,
                           including, without limitation, any adverse change in
                           the Employee's status or position as a result of a
                           material diminution in his or her duties or
                           responsibilities (other than, if applicable, any such
                           change directly attributable to the fact that the
                           Company is no longer publicly owned) or the
                           assignment to the Employee of any duties or
                           responsibilities that, in the Employee's reasonable
                           responsibilities that, in the Employee's reasonable
                           judgment, are inconsistent with such status or
                           position, or any removal of the Employee from or any
                           failure to reappoint or reelect the Employee to such
                           position (except in connection with the termination
                           of his employment "for cause" or as a result of his
                           death or Total Disability or by the Employee other
                           than for Good Reason); provided, however, that Good
                           Reason will not include an adverse change in the
                           Employee's status 


<PAGE>


                           or position caused by an insubstantial and
                           inadvertent action that is remedied by the Company
                           promptly after receipt of written notice of such
                           change from the Employee;

                  (2)      a reduction by the Company in the Employee's annual
                           Base Salary, or an adverse change in the form or
                           timing of the payment thereof, as in effect
                           immediately prior to the Change in Control or as
                           thereafter increased;

                  (3)      the failure by the Company to continue in effect any
                           benefit plan in which the Employee (including, for
                           purposes of this paragraph, his family or dependents)
                           is participating at any time during the 90-day period
                           immediately preceding the Change in Control (or
                           benefit plans providing the Employee with at least
                           substantially similar benefits) other than as a
                           result of the normal expiration of any such benefit
                           plan in accordance with its terms as in effect
                           immediately prior to the 90-day period immediately
                           preceding the Change in Control, or the taking of any
                           action, or the failure to act, by the Company that
                           would adversely affect an Employee's continue
                           participation in any of such benefit plans on at
                           least as favorable a basis to such Employee as is the
                           case immediately prior to the Change in Control or
                           that would materially reduce the Employee's benefits
                           in the future under any such benefit plans or deprive
                           an Employee of any material benefit enjoyed by such
                           Employee immediately prior to the Change in Control;

                  (4)      the Company's requiring the Employee to be based more
                           than 30 miles from where his or her office is located
                           immediately prior to the Change in Control, except
                           for required travel pursuant to the Company's
                           business travel obligations that the Employee
                           undertook on behalf of the Company during the 90-day
                           period immediately preceding the Change in Control;

                  (5)      the failure of the Company to obtain an assumption of
                           the obligations of the Company to perform this
                           Agreement by any successor to the Company; or

                  (6)      any material breach of this Agreement by the Company.

         8) Inventions.

         (a) "Inventions," as used in this Section 8, means any discoveries,
         improvements, formulae, proprietary rights or data, trade secrets, shop
         rights, (whether or not they are in writing or reduced to practice) or
         works of authorship (whether or not they can be patented or
         copyrighted) that the Employee makes, authors, or conceives (either
         alone or with others) and that:


<PAGE>


                  (1)      concern directly the Company's business or the
                           Company's present or possible future research or
                           development;

                  (2)      result from any work the Employee performs for the
                           Company;

                  (3)      use the Company's equipment, supplies, facilities, or
                           trade secret information; or

                  (4)      the Employee develops during any such time that
                           Section 2 above obligates him to perform his
                           employment duties.

         (b) The Employee agrees that all Inventions he makes during or within
         six months after the term of this Agreement will be the Company's sole
         and exclusive property; and that all works of authorship that may be
         the subject of copyright protection shall be "works made for hire." The
         Employee will, with respect to any such Invention:

                  (1) keep current, accurate, and complete records, which will
                  belong to the Company and be kept and stored on the Company's
                  premises while the Employee is employed by the Company;

                  (2) promptly and fully disclose the existence and describe the
                  nature of the Invention to the Company in writing (and without
                  request);

                  (3) assign (and the Employee does hereby assign) to the
                  Company all of his rights to the Invention, any applications
                  he makes for patents or copyrights in any country, and any
                  patents or copyrights granted to him in any country; and

                  (4) acknowledge and deliver promptly to the Company any
                  written instruments, and perform any other acts necessary in
                  the Company's opinion to preserve property rights in the
                  Invention against forfeiture, abandonment, or loss and to
                  obtain and maintain letters patents and/or copyrights on the
                  Invention and to vest the entire right and title to the
                  Invention in the Company.

         The requirements of this subsection 8(b) do not apply to an Invention
         for which no equipment, supplies, facility or trade secret information
         of the Company was used and which was developed entirely on the
         Employee's own time, and (x) which does not relate directly to the
         Company's business or to the Company's actual or demonstrably
         anticipated research or development, or (y) which does not result from
         any work the Employee performed for the Company. Except as previously
         disclosed to the Company in writing, the Employee does not have, and
         will not assert, any claims to or rights under any Inventions as having
         been made, conceived, authored or acquired by the Employee prior to his
         employment by the Company.

         9) Confidential Information and Trade Secrets. Employee recognizes and
acknowledges that he may have access to confidential information and trade
secrets concerning

limitation, books and records relating to operation, finances, cash, bank
accounts, accounting; sales personnel and management; actual and potential

maintenance costs; pricing matters; market place analyses; computer software;
database programs; and internal procedures, standards and productivity tools.
The protection of this confidential information and trade secrets against
authorized disclosure and use is of critical important to Company, and Employee
agrees that he will not, directly or indirectly, at any time while employed by
company and within two (2) years after termination with Company, with or without
cause, make any independent use of, or disclosure to any person other than an
employee of Company, or any organization except as authorized by Company, any
confidential information or trade secrets of Company. This provision shall not
be applicable to information disclosed by the Employee during testimony under
subpoena in any court or before any administrative agency or during any
governmental inquiry or investigation.

         10) Competitive Activities. The Employee agrees that during his
employment with the Company and for a period of two years after his employment
with the Company ends:

         (a)      He will not alone, or in any capacity with another firm or
                  person:

                  (1)      directly or indirectly engage in any commercial
                           activity that competes with the Company's business,
                           as the Company has conducted it during the five years
                           before the Employee's employment with the Company
                           ends, (A) within any state in the United States, or
                           (B) within any country in which the Company directly
                           or indirectly markets or services products or
                           provides services or reasonably intends during such
                           period to market or service products or provide
                           services;

                  (2)      in any way interfere or attempt to interfere with the
                           Company's relationships with any of its current or
                           potential customers; or

                  (3)      employ or attempt to employ any of the Company's then
                           employees on behalf of any other entity competing
                           with the Company.

         (b)      He will, prior to accepting employment with any new employer,
                  inform that employer of this Agreement and provide that
                  employer with a copy of this Agreement.

         (c)      Nonsolicitation. The Employee further agrees that during his
                  employment and for a period of two years after his employment
                  with the Company ends, that he will not directly or
                  indirectly:


<PAGE>


                  (1)      Induce any customers of Company to patronize any
                           similar business which competes with Company;

                  (2)      canvas, solicit, or accept any similar business from
                           any customer of Company;

                  (3)      request or advise any customers of Company to
                           withdraw, reduce, or cancel such customer's business
                           with Company;

                  (4)      disclose to any other person, firm, partnership, or
                           corporation the names, addresses or telephone
                           numbers, or other protected information of any of the
                           customers of Company; or,

                  (5)      induce, canvas, solicit, request or advise any
                           employees of Company, to accept employment with any
                           person, firm or business which competes with any
                           business of Company.

         11) Conflicting Business. The Employee agrees that he will not transact
business with the Company personally, or as agent, owner, partner or shareholder
of any other entity; provided, however, that the Employee may enter into any
business transaction that is, in the opinion of the Board, reasonable, prudent
or necessary to the Company, so long as any such business transaction is at
arm's length as though between independent and prudent individuals.

         12) No Adequate Remedy. The Employee understands that if he fails to
fulfill his obligations under this Agreement, the damages to the Company would
be very difficult to determine. Therefore, in addition to any other rights or
remedies available to the Company at law, in equity or by statute, the Employee
hereby consents to the specific enforcement by the Company of Sections 8, 9 and
10 of this Agreement through an injunction or restraining order issued by an
appropriate court. The Employee will also be reasonable for the Company's costs
and attorneys' fees incurred by the Company in enforcing any of the provisions
of this Agreement.

         13) Indemnification. The Company shall indemnify the Employee for all
acts as an officer and director of the Company to the fullest extent permitted
by the Articles of Incorporation, the Bylaws of the Company and Minnesota law.
The Employee shall also be covered by the Company's directors' and officers'
insurance policy.

         14) Miscellaneous.

         (a)      Successors and Assigns. Except as provided in the next
                  sentence, this Agreement may not be assigned without the
                  Employee's consent, which consent will not be unreasonably
                  withheld. In any event, the Company may assign this Agreement
                  without the consent of the Employee in connection with a
                  merger, consolidation, assignment, sale, or other disposition
                  of substantially all of its assets or business.


<PAGE>


         (b)      Modification. This Agreement may be modified or amended only
                  by a writing signed by each of the parties hereto.

         (c)      Governing Law. The laws of the State of Minnesota will govern
                  the validity, construction, and performance of this Agreement,
                  without regard to the conflict of laws provisions of any other
                  jurisdictions. Any legal proceeding related to this Agreement
                  will be brought in an appropriate Minnesota court, and each of
                  the parties hereto hereby consents to the exclusive
                  jurisdiction of that court for this purpose.

         (d)      Construction. Wherever possible, each provision of this
                  Agreement will be interpreted so that it is valid under
                  applicable law. If any provision of this Agreement is to any
                  extent invalid under applicable law in any jurisdiction, that
                  provision will still be effective to the extent it remains
                  valid. The remainder of this Agreement also will continue to
                  be valid, and the entire Agreement will continue to be valid
                  in other jurisdictions.

         (e)      Non-Waiver. No failure or delay by either the Company or the
                  Employee in exercising any right or remedy under this
                  Agreement will waive any provision of the Agreement. Nor will
                  any single or partial exercise by either the company or the
                  Employee of any right of remedy under this Agreement preclude
                  either of them from otherwise or further exercising these
                  rights or remedies, or any other rights or remedies granted by
                  any law or any related document.

         (f)      Counterparts. This Agreement may be executed in two or more
                  counterparts, each of which will constitute one and the same
                  instrument.

         (g)      Entire Agreement. This Agreement supersedes all previous and
                  contemporaneous oral negotiations, commitments, writings, and
                  understandings among the parties hereto concerning the matters
                  in this Agreement, including, without limitation, any policy
                  or personnel manuals of the Company or any of its subsidiaries
                  or affiliates.

         (h)      Notices. All notices and other communications required or
                  permitted under this Agreement will be in writing and hand
                  delivered or sent by registered first-class mail, postage
                  prepaid, and will be effective upon receipt if hand delivered,

                  the following addresses or such other addresses as either

                        AMENDMENT TO EMPLOYMENT AGREEMENT

         This Amendment ("Amendment") is made and entered into effective as of
November 13, 1997, by and between LifeRate Systems, Inc., a Minnesota
corporation (the "Company"), and David J. Chinsky (the "Employee").

                                    RECITALS

         A. The Company and the Employee entered into an Employment Agreement,
dated as of August 18, 1997, (the "Employment Agreement"), pursuant to which the
Company has agreed to employ the Employee as its Chief Executive Officer and
President.

         B. The Company intends to issue and sell an aggregate of approximately
9,000,000 shares of common stock ("Common Stock") at prices ranging from $.50 to
$.56 per share and warrants to purchase approximately 9,000,000 shares of Common
Stock (the "Financing") to certain investors, including Special Situations
Private Equity Fund, L.P., Special Situations Fund III, L.P. and Special
Situations Cayman Fund, L.P. (the "Investors"), which would result in a "Change
in Control" as defined in Section 6 of the Employment Agreement.

         C. The Company desires to amend the Employment Agreement such that the
Financing would not result in a Change of Control under the Employment Agreement
or any stock option agreements between the Company and the Employee issued
pursuant to the Employment Agreement.

         D. In order to facilitate the completion of the Financing, the Employee
has agreed to waive his right with respect to a portion of additional options
that he would otherwise be entitled to receive under the Employment Agreement as
result of the Financing.

         E. The Employee is willing to enter into this Amendment in exchange for
adjustment to the exercise price of options to purchase shares of Common Stock
granted, or to be granted, by the Company to the Employee pursuant to the
Employment Agreement and the grant of additional options.

         Accordingly, the parties, each intending to be legally bound, hereby
agree as follows:

         1. Amendment to Exercise Price of Stock Options. Section 5(b) of the
Employment Agreement is hereby amended to the extent necessary to provide that
the exercise price of the options referred to therein, including any options
that the Company may be obligated to issue pursuant to the second and third
paragraphs thereof, shall be $0.50 per share.

         2. Amendment of Definition of Change in Control. Section 6(b) of the
Employment Agreement is hereby amended in its entirety as follows:

         (b) For purposes of this Section 6, the Incumbent Directors will mean
         any individuals who are members of the Board immediately following the
         first closing of the Financing (relating to 2,500,000 shares and
         warrants to purchase 2,500,000 


<PAGE>


         shares), any individual who is elected to the Board pursuant to the
         Securities Purchase Agreement pursuant to which the securities sold in
         the Financing will be issued and any individual who subsequently
         becomes a member of the Board whose election, or nomination for
         election by the Company's shareholders, was approved by a vote of at
         least a majority of the Incumbent Directors then in office (either by
         specific vote or by approval of the Company's proxy statement in which
         such individual is named as a nominee for director without objection to
         such nomination).

         Section 6 of the Employment Agreement is hereby amended by adding the
following subsection (d) at the end thereof:

         (d) Notwithstanding any other provision of this Agreement, if Special
         Situations Private Equity Fund, L.P., Special Situations Fund III, L.P.
         or Special Situations Cayman Fund, L.P. (collectively, "Special
         Situations Fund") shall become, individually or collectively, in one or
         more transactions, the "beneficial owner", of any of the Company's
         securities, such ownership, regardless of the percentage of the
         Company's combined voting power owner or controlled, shall not
         constitute a "Change in Control", whether or not the issuance of such
         securities by the Company to Special Situations Fund would be required
         to be reported pursuant to Section 13 or 15(d) of the Exchange Act.

         Notwithstanding any other provision of the Employment Agreement or this
Agreement, the election of directors pursuant to the Securities Purchase
Agreement pursuant to which securities will be sold in the Financing shall not
constitute a "Change in Control" under the Employment Agreement.

         3. Stock Options. The Company and the Employee acknowledge and agree
that the Employee will be entitled to options to purchase an aggregate of
650,000 shares of Common Stock at a price of $.50 per share pursuant to Section
5(b) of the Employment Agreement following completion of the Financing, and the
Employee hereby waives his right to receive any additional options under the
Employment Agreement as a result of the Financing. At or before the closing of
the Financing, the Company and the Employee shall enter into a stock option
agreement, in the form attached hereto as Exhibit A, covering 650,000 shares of
Common Stock at a purchase price of $.50 per share, representing the aggregate
number of options to which the Employee will be entitled pursuant to Section
5(b) of the Employment Agreement following completion of the Financing.

         4. Bonus. Section 5(c) of the Employment Agreement is amended to the
extent necessary to provide that, at the option of the Company, any bonus that
becomes due and payable under Section 5(c) of the Employment Agreement may be
paid in cash or shares of Common Stock having a fair market value, at the time
such bonus becomes due and payable, equal to the amount of such bonus, or any
combination of cash and shares of Common Stock. The Company shall pay the
Employee the $108,000 bonus payable pursuant to Section 5(d) of the Employment
Agreement within fifteen (15) days of the first closing of the Financing
(relating to 2,500,000 


<PAGE>


shares and warrants to purchase 2,500,000 shares). Notwithstanding anything to
the contrary in this Section 4, the Employee acknowledges that if payment in
shares of Common Stock of any bonus payable under Section 5(c) of the Employment
Agreement would result in an adjustment in the exercise price or conversion
price of any option, warrant, convertible note or other security or right in
existence on the date of such payment, or would result in an adjustment in the
number of shares purchasable under such an option, warrant, convertible note or
other security or right, then such bonus shall be paid in cash.

         5. No Other Amendment. Except as set forth herein, the Employment
Agreement shall remain in full force and effect in accordance with its original
terms.

         IN WITNESS WHEREOF, the Company and the Employee have executed this
Amendment as of the date first written above.

                      NON-STATUTORY STOCK OPTION AGREEMENT

         THIS AGREEMENT is entered into and effective as of November 13, 1997
(the "Date of Grant"), by and between LifeRate Systems, Inc. (the "Company") and
David J. Chinsky (the "Optionee").

            A. The Optionee has entered into an Employment Agreement with the
Company dated August 18, 1997, as amended on November 13, 1997 (as amended, the
"Employment Agreement"), pursuant to which the Optionee is employed by the
Company as President and Chief Executive Officer.

            B. Pursuant to the Employment Agreement, the Company has agreed to
grant to the Optionee certain options to purchase shares of common stock, and
the Company desires to advance the interests of the Company by granting to the
Optionee an option to purchase shares of common stock of the Company.

            C. The Company intends to issue and sell an aggregate of
approximately 9,000,000 shares of common stock ("Common Stock") at prices
ranging from $.50 to $.56 per share and warrants to purchase approximately
9,000,000 shares of Common Stock (the "Financing") to certain investors,
including Special Situations Private Equity Fund, L.P., Special Situations Fund
III, L.P. and Special Situations Cayman Fund, L.P. Upon completion of the
Financing, the Optionee will become entitled to certain options under the second
and third paragraphs of Section 5(b) of the Employment Agreement.

            D. Although the option being granted pursuant to this Agreement is
not being granted under any formal stock option plan of the Company, capitalized
terms that are not defined herein shall have the meaning set forth in the
Employment Agreement or the Company's 1993 Stock Option Plan (the "Plan"), as
the case may be, as such agreement or plan may be amended from time to time.

         Accordingly, the parties hereby agree as follows:

Agreement. The Option is not intended to be an "incentive stock option," as that

(the "Code").

                  (a) In the event that the Optionee's employment or other
         service with the Company and all Subsidiaries (as defined in the Plan)
         is terminated by reason of the Optionee's death, Total Disability (as
         defined in the Employment Agreement) or Retirement (as defined in the
         Plan), this Option shall remain exercisable to the extent exercisable
         as of such termination for a period of one year after such termination
         in the case of death or Total Disability or January 31, 2000, whichever
         is later, and three months in the case of Retirement or January 31,
         2000, whichever is later (but in no event after the Time of
         Termination).

                  (b) In the event the Optionee's employment or other service
         with the Company and all Subsidiaries is terminated for any reason
         other than death, Total Disability or Retirement, all rights of the
         Optionee under this Agreement shall immediately terminate without
         notice of any kind, and this Option shall no longer be exercisable;
         provided, however, that if such termination is due to any reason other
         than termination by the Company or any Subsidiary "for cause" (as
         defined in the Employment Agreement), this Option shall remain
         exercisable to the extent exercisable 


<PAGE>


         as of such termination for a period of thirty (30) days or January 31,
         2000, whichever is later (but in no event after the Time of
         Termination).

                  (c) Notwithstanding anything in this Agreement to the
         contrary, in the event that the Optionee materially breaches the terms
         of Sections 9 or 10 of the Employment Agreement, whether such breach
         occurs before or after termination of the Optionee's employment or
         other service with the Company or any Subsidiary, the Committee in its
         sole discretion may immediately terminate all rights of the Optionee
         under this Agreement without notice of any kind.

         3.3. Change in Control.

                  (a) For purposes of this Section 3.3, the term "Change in
         Control" shall have the meaning set forth in Section 6 of the
         Employment Agreement, as may be amended from time to time, whether
         before or after the date hereof.

                  (b) If any events constituting a Change in Control of the
         Company shall occur, then this Option shall become immediately
         exercisable in full until the Time of Termination, whether or not the
         Optionee remains in the employ or service of the Company or any
         Subsidiary. In addition, if a Change in Control of the Company shall
         occur, the Committee, in its sole discretion, and without the consent
         of the Optionee, may determine that the Optionee shall receive, with
         respect to some or all of the Option Shares, as of the effective date
         of any such Change in Control of the Company, cash in an amount equal
         to the excess of the Fair Market Value (as defined in the Plan) of such
         Option Shares immediately prior to the effective date of such Change in
         Control of the Company over the option exercise price per share of this
         Option.

                  (c) Notwithstanding anything in this Section 3.3 to the
         contrary, if, with respect to the Optionee, acceleration of the
         exercisability of this Option or the payment of cash in exchange for
         all or part of this Option as provided above (which acceleration or
         payment could be deemed a payment within the meaning of Section
         280G(b)(2) of the Code), together with any other payments which the
         Optionee has the right to receive from the Company or any corporation
         which is a member of an "affiliated group" (as defined in Section
         1504(a) of the Code without regard to Section 1504(b) of the Code) of
         which the Company is a member, would constitute a "parachute payment"
         (as defined in Section 280G(b)(2) of the Code), then the acceleration
         of exercisability and the payments to the Optionee as set forth herein
         shall be reduced to the largest amount as, in the sole judgment of the
         Committee, will result in no portion of such payments being subject to
         the excise tax imposed by Section 4999 of the Code; provided, that such
         reduction shall be made only if the aggregate amount of the payments
         after such reduction exceeds the difference between (A) the amount of
         such payments absent such reduction minus (B) the aggregate amount of
         the excise tax imposed under section 4999 of the Code attributable to
         any such excess parachute payments arising in connection with such
         Change in Control. The determination as to whether any such decrease in
         the payments to be made in connection with this Agreement is necessary
         must be made in good faith by legal counsel or 


<PAGE>


         a certified public accountant selected by the Company and reasonably
         acceptable to the Optionee, and such determination will be conclusive
         and binding. In the event that a reduction is necessary, the Optionee
         will have the right to designate the particular payments or benefits
         that are to be reduced or eliminated so that no portion of the payments
         or benefits to be made or provided to the Optionee will be excess
         parachute payments subject to the excise tax under Code section 4999.

         3.4. Cancellation of Option. This Option shall become exercisable if,
and only if, the first closing of the Financing (relating to approximately
2,500,000 shares and warrants to purchase approximately 2,500,000 shares) (the
"First Closing") is completed by December 31, 1997. If the first closing of the
Financing is not completed by such date, this Option shall become null and void,
the Optionee shall not have any right to purchase any shares of Common Stock
hereunder, and the Prior Option Agreements, as defined below, shall remain in
full force and effect.

                            MANNER OF OPTION EXERCISE

         4.1. Notice. This Option may be exercised by the Optionee in whole or
in part from time to time, subject to the conditions contained herein, by
delivery, in person or by registered mail, to the Company at its principal
executive office in Edina, Minnesota (Attention: Chief Financial Officer), of a
written notice of exercise. Such notice shall be in a form satisfactory to the
Committee, shall identify the Option, shall specify the number of Option Shares
with respect to which the Option is being exercised, and shall be signed by the
person or persons so exercising the Option. Such notice shall be accompanied by
payment in full of the total purchase price of the Option Shares purchased. In
the event that the Option is being exercised by any person or persons other than
the Optionee (such as by the Optionee's heir(s) or legal representative(s), in
the event of death or disability of Optionee), the notice shall be accompanied
by appropriate proof of right of such person or persons to exercise the Option.
As soon as practicable after the effective exercise of the Option, the Optionee
shall be recorded on the stock transfer books of the Company as the owner of the
Option Shares purchased, and the Company shall deliver to the Optionee one or
more duly issued stock certificates evidencing such ownership.

         4.2. Payment. At the time of exercise of this Option, the Optionee
shall pay the total purchase price of the Option Shares to be purchased solely
in cash (including a personal check or a certified or bank cashier's check,
payable to the order of the Company); provided, however, that the Committee, in
its sole discretion, may allow such payments to be made, in whole or in part, by
delivery of a Broker Exercise Notice or a promissory note (containing such terms
and conditions as the Committee may in its discretion determine), by transfer
from the Optionee to the Company of Previously Acquired Shares, or by a
combination thereof. For purposes of this Agreement, the terms "Broker Exercise
Notice" and "Previously Acquired Shares" shall have the meanings set forth in
the Plan. In the event the Optionee is permitted to pay the total purchase price
of this Option in whole or in part with Previously Acquired Shares, the value of
such shares shall be equal to their Fair Market Value on the date of exercise of
this Option.

         4.3. Investment Purpose. The Company shall not be required to issue or
deliver any shares of Common Stock under this Option unless (1)(a) such shares
are covered by an effective and current registration statement under the
Securities Act of 1933 and applicable state securities laws or (b) if the
Committee has determined not to so register such shares, exemptions from
registration under the Securities Act of 1933 and applicable state securities
laws are available for such issuance (as determined by counsel to the Company)
and the Company has received from the Optionee (or, in the event of death or
disability, the Optionee's heir(s) or legal representative(s)) any
representations or agreements requested by the Company in order to permit such
issuance to be made pursuant to such exemptions, and (2) the Company has
obtained any other consent, approval or permit from any state or federal
governmental agency which the Committee shall, in its sole discretion upon the
advice of counsel, deem necessary or advisable. In the event that, at the time
of the attempted exercise of this Option, any of these conditions to the
issuance of a certificate for shares of Common Stock have not been satisfied,
such exercise shall be deemed withdrawn and the Company shall return any
payments made with respect thereto unless the Optionee, within 15 days after
being informed of the nonsatisfaction of such conditions, gives the Company
written notice that he or she wants such exercise to remain suspended (in which
event such exercise shall be deemed to be effective on the earliest date upon
which such conditions have been satisfied). Unless a registration statement
under the Securities Act of 1933 is in effect with respect to the issuance or
transfer of Option Shares, each certificate representing any such shares shall
be restricted by the Company as to transfer unless the Company receives an
opinion of counsel satisfactory to the Company to the effect that registration
under the Securities Act of 1933 and applicable state securities laws is not
required with respect to such transfer.

                               NONTRANSFERABILITY

         Other than pursuant to a qualified domestic relations order (as defined
in the Code), no right or interest of the Optionee in this Option prior to the
exercise of such Option shall be assignable or transferable, or subjected to any
lien, during the lifetime of the Optionee, either voluntarily or involuntarily,
directly or indirectly, by operation of law or otherwise, including execution,
levy, garnishment, attachment, pledge, divorce or bankruptcy. The Optionee
shall, however, be entitled to designate a beneficiary to receive the Option
upon such Optionee's death. In the event of the Optionee's death, such
Optionee's rights and interest in the Option shall be transferable by
testamentary will or the laws of descent and distribution, and exercise of the
Option may be made by the Optionee's legal representatives, heirs or legatees.
Any attempt to transfer or encumber this Option other than in accordance with
this Agreement shall be null and void and shall void this Option.

                             LIMITATION OF LIABILITY

         Nothing in this Agreement shall be construed to (a) limit in any way
the right of the Company to terminate the employment or service of the Optionee
at any time, or (b) be evidence of any agreement or understanding, express or
implied, that the Company will retain the Optionee in any particular position,
at any particular rate of compensation or for any particular period of time.

                                WITHHOLDING TAXES

         The Company is entitled to (a) withhold and deduct from future wages of
the Optionee (or from other amounts which may be due and owing to the Optionee
from the Company), or make other arrangements for the collection of, all legally
required amounts necessary to satisfy any federal, state or local withholding
and employment-related tax requirements attributable to the grant or exercise of
this Option or otherwise incurred with respect to this Option, or (b) require
the Optionee promptly to remit the amount of such withholding to the Company
before acting on the Optionee's notice of exercise of this Option. In the event
that the Company is unable to withhold such amounts, for whatever reason, the
Optionee hereby agrees to pay to the Company an amount equal to the amount the
Company would otherwise be required to withhold under federal, state or local
law.

                                   ADJUSTMENTS

         In the event of any reorganization, merger, consolidation,
recapitalization, liquidation, reclassification, stock dividend, stock split,
combination of shares, rights offering, extraordinary dividend or divestiture
(including a spin-off) or any other change in the corporate structure or shares
of the Company, the Committee (or, if the Company is not the surviving
corporation in any such transaction, the board of directors of the surviving
corporation), in order to prevent dilution or enlargement of the rights of the
Optionee, shall make appropriate adjustment (which determination shall be
conclusive) as to the number, kind and exercise price of securities subject to
this Option.

hereunder shall be governed by the laws of the State of Minnesota.

         9.3. Entire Agreement. This Agreement and the Employment Agreement set
forth the entire agreement and understanding of the parties hereto with respect
to the grant and exercise of this Option and supersede all prior agreements,
arrangements, plans and understandings relating to the grant and exercise of
options to purchase shares of Common Stock. The Non-Statutory Stock Option
Agreements, dated August 26, 1997, between the Company and the Optionee,
covering 200,000 and 100,000 shares, respectively (the "Prior Option
Agreements"), shall be canceled effective upon completion of the First Closing,
provided that such First Closing occurs by December 31, 1997. The Company and
the Optionee acknowledge that this Option satisfies the Company's obligation to
issue options under the second and third paragraphs of Section 5(b) of the
Employment Agreement as a result of the Financing.

registered under the Securities Act of 1933 on a Registration Statement on Form
S-8 (or any successor form); provided that the Company shall not be required to
file such Form S-8 prior to January 1, 2000.

         The parties hereto have executed this Agreement effective the day and
year first above written.
