     or under any instrument by which the Company or any Subsidiary is bound, in
     each case which default materially and adversely affects the business,
     operations, assets, financial condition or prospects of the Company and its
     subsidiaries taken as a whole.

     of employment, nor is there any strike involving the Company or any of its
     Subsidiaries pending or, to the knowledge of its executive officers,

     reorganization or has been terminated within the meaning of Title IV of
     ERISA, and has no Multiemployer Plan that is reasonably expected to be in
     reorganization or to be terminated where such reorganization or termination
     has had or could reasonably be expected to have, through increases in the
     contributions required to be made or otherwise, a material adverse effect
     on the business, condition, operations (financial or otherwise) or
     prospects of the Company and its Subsidiaries taken as a whole.

     Purchaser and the consummation by the Purchaser of the transactions
     contemplated hereby have been duly authorized by all necessary corporate
     action on behalf of the Purchaser.  This Agreement has been duly executed
     and delivered by the Purchaser and constitutes a valid and binding
     agreement of the Purchaser enforceable against the Purchaser in accordance
     with its terms, except that (i) such enforcement may be subject to

     the purpose of investment and not with a view to or for sale in connection
     with any "distribution" (within the meaning of the Securities Act) thereof,
     and the Purchaser has no present intention or plan to effect any
     distribution of the Shares, the Warrants or the Underlying Series A

                -----------------------------------------                   
     take all permissible and appropriate action to ensure that one person
     selected by Purchaser is nominated and elected to serve on the Company's
     board of directors (it being understood that, notwithstanding the
     introduction to Section 4, the Company's obligations under this Section 4.4
     commence on the Closing Date).

          4.6  Share Repurchases.  (a)  The Company will not repurchase or
               -----------------                                          
     redeem any shares of any Common Stock or its other equity securities if,
     after giving effect to such repurchase or redemption, either (i) the Shares
     of Common Stock owned by the Purchaser and its Affiliates would equal or
     exceed 5.0% of the Company's Outstanding Common Stock or (ii) the Purchaser
     Shares (as defined in Section 7.12) owned by the Purchaser and its
     Affiliates would equal or exceed 15% of the Company's Outstanding Common
     Stock (the circumstances described in clause (i) and (ii) above each a

     Section 4.6.  For purposes of the foregoing, the term "Outstanding" means
     shares issued and outstanding, includes shares of Common Stock which the
     Purchaser may acquire directly or indirectly upon exercise of the Warrant

     convertible securities or other similar instruments owned by any Person
     other than the Company or an affiliate of the Company.

          (b)  In the event a proposed repurchase or redemption would cause the
     Company to cross a Threshold, at least 30 days before such repurchase or
     redemption the Company shall (i) notify the Purchaser of such proposed
     repurchase or redemption and (ii) offer to repurchase or redeem such number
     of Purchaser Shares owned by the Purchaser or its Affiliates as necessary
     to prevent the proposed purchase or redemption from causing the Company to
     cross a Threshold on substantially the same terms (as to both consideration
     and timing) as are applicable to the proposed repurchase or redemption of
     such other shares.

                                      12

 
          4.7  Additional Ventures.  Subject to the last two sentences of this
               -------------------                                            
     Section 4.7, in the event the Company proposes to join with any third-party
     who is not an Affiliate (an "unaffiliated Third-Party"), whether through a
     joint venture, partnership, co-ownership of another entity or otherwise
     (each a "Venture"), to provide cash management or data processing services
     or related technology and related services to customers or potential
     customers, the Company agrees that it will first explore in good faith with
     the Purchaser whether the Purchaser or one of its Affiliates desires to
     join with the Company in developing the Venture.  If the Purchaser or one
     of its Affiliates does wish to join with the Company in developing such
     Venture, the Company and the Purchaser or such Affiliate of the Purchaser
     will negotiate in good faith for a reasonable period of time to establish
     mutually acceptable terms and conditions upon which the Company and the
     Purchaser or its Affiliates may establish such Venture.  This Section 4.7
     will not apply if an unaffiliated Third Party proposes to contribute as an
     integral part of the Venture products or services (other than healthcare
     decision support information products or services) or good will which is
     not reasonably believed by the Company to be available from Purchaser or
     its Affiliates.  For purposes hereof, "healthcare decision support
     information products or services" means products or services which
     facilitate the accumulation, manipulation and repackaging of healthcare
     data for marketing to the healthcare industry.

          4.8  Conduct of Business.  Prior to the earlier of (i) the Closing
               -------------------                                          
     Date and (ii) December 31, 1994, the Company and its Subsidiaries will
     conduct their businesses only in the ordinary and usual course of such
     businesses and will not issue any additional equity securities except
     pursuant to a Plan.

     5.  Additional Shares.
         ----------------- 

          In the event that, during any calendar quarter (treating the period
     from the date of this Agreement through December 31, 1994 as a calendar
     quarter for purposes of this Section 5) on the first day of which the
     Purchaser (together with its Affiliates) owns a minimum of 500,000
     Purchaser Shares (as defined in Section 7.12), the Company shall issue
     additional shares of Common Stock ("Additional Third-Party Shares")
     otherwise than (i) to employees of the Company or its Subsidiaries, other
     than pursuant to options, warrants or other rights to acquire such shares
     granted to such employees, in an aggregate amount of not more than 100,000
     shares per calendar year, (ii) pursuant to options, warrants or other
     rights granted to employees of the Company or a Subsidiary (and not
     transferable to any Person who is not an employee of the Company or a
     Subsidiary) to acquire such shares at prices not less than the market price
     thereof (as defined in Section 6(h) of the Certificate of Designation) on
     the date of the grant of each such option, warrant or other right, or (iii)
     pursuant to

                                      13

 
     a Plan, on or before the fifth day after the end of such calendar quarter
     the Company shall offer to issue to the Purchaser additional shares of
     Common Stock ("Additional Common Shares") or additional shares of Series A
     Preferred Stock ("Additional Series A Preferred Shares") in accordance with
     this Section 5.1.  In each such case:

               (i)  the number of Additional Shares so offered shall equal 17.6%
          of the number of Additional Third-Party Shares issued during such
          calendar quarter (rounded to the nearest whole share), and 33-1/3% of
          the Additional Shares so offered to the Purchaser shall be Additional
          Common Shares and 66-2/3% of the Additional Shares so offered shall be
          Additional Series A Preferred Shares;

               (ii)  except as otherwise provided in clause (iii), below, the
          offer price of each Additional Share so offered shall be determined by
          dividing the aggregate of the consideration received by the Company
          with respect to the Additional Third-Party Shares issued during such
          calendar quarter by the total number of such Additional Third-Party
          Shares so issued (provided, however, that if any of the events
                            --------  -------                           
          described in Section 6 of the Certificate of Designation giving rise
          to an adjustment in the Conversion Rate (as defined therein) shall
          theretofore have occurred, for purposes of this Section 5 an
          Additional Series A Preferred Share shall be deemed to be such
          fraction or multiple of a Series A Preferred Share which would, after
          giving effect to such event, produce a Conversion Rate of 1.00), and

               (iii)  if the Additional Third-Party Shares were issued pursuant
          to options, warrants or other similar rights to acquire such shares
          and such options, warrants or other similar rights were themselves
          issued in a Permitted Transaction, the offer price of each Additional
          Share so offered shall be the market price thereof (as defined in
          Section 6(h) of the Certificate of Designation) determined as of the
          last business day of the applicable calendar quarter.  ("Permitted
          Transaction", as used in this clause (iii), means a transaction in
          which the Company acquires assets or a business operation from a
          Person or Persons who are not affiliates of the Company and, in
          connection with such acquisition, issues to such Person or Persons or
          their employees options, warrants or other similar rights to acquire a
          number of shares of the Company's Common Stock up to (but not
          exceeding 500,000.

     The Company's offer to the Purchase shall be in writing and shall set forth
     a calculation of the applicable offer price.  The Purchaser may accept such
     offer on or before the 15th day after such offer is received by it by
     paying to the Company, at its office set forth in Section 7.5 (and in
     immediately available funds), an amount determined as described above, and

                                      14

 
     the Company shall thereupon issue the appropriate number of Additional
     Common Shares and Additional Series A Preferred Shares to the Purchaser.
     The Company shall not at any time issue additional shares of Common Stock
     (otherwise than pursuant to a Plan) unless at the same time it takes all
     corporate action necessary and reserves for issuance a sufficient number of
     shares of Common Stock and Series A Preferred Stock to carry out its
     obligations under this Section 5.1.

     issuance and delivery of the Shares, for a period of three years from the
     latest date set forth under the signatures hereto, regardless of any
     investigation made by or on behalf of any party.

          7.12.  Transfer of Shares.
                 ------------------ 

               (a)  The term "Purchaser Shares", as used in this Section 7.12,
          means at any point in time (x) the Common Shares then owned by the
          Purchaser or its Affiliates, (y) the shares of Common Stock issuable
          upon conversion of the Series A Preferred Shares then owned by the
          Purchaser or its Affiliates, and (z) the Warrants and Series A
          Preferred Shares then owned by the Purchaser or its Affiliates or
          issuable upon exercise of the Warrants (excluding, however, any shares
          of Common Stock acquired by the Purchaser or its Affiliates from
          Persons other than the Company).  The term "Free Purchaser Shares"
          means (i) from the Closing Date through the date nine months
          thereafter, 0% of the Purchaser Shares, (ii) thereafter through the
          date two years after the Closing Date, 66-2/3% of the Purchaser Shares
          as they exist as of the first day of such period, and (iii) thereafter
          100% of the Purchaser Shares (with such percentages calculated based
          upon the sum of the number of shares of Common Stock (x) owned by the
          Purchaser and its Affiliates, (y) with respect to Series A Preferred
          Shares, issuable upon exercise of Series A Preferred Shares owned by
          the Purchaser or its Affiliates, and (z) with respect to the Warrants,
          issuable upon conversion of underlying Series A Preferred Shares
          issuable upon exercise of the Warrants).

               (b) the Purchaser understands and agrees that the Shares and the
          Warrants have not been, and the Underlying Series A Preferred Shares
          at the time of their delivery upon exercise of the Warrants and any
          Additional Shares upon their issuance and delivery will not have been,
          registered under the Securities Act or the securities laws of any
          state and that they may be sold or otherwise disposed of only in one
          or more transactions registered under the Securities Act and, where
          applicable, such laws, or as to which an exemption from the
          registration requirements of the Securities Act and, where applicable,
          such laws are available.  The Purchaser understands and agrees that
          each certificate representing the Shares, Warrants, Underlying Series
          A Preferred Shares and Additional Shares shall bear, until so
          registered or until a holder of such Shares causes to be delivered to
          the Company an opinion of counsel reasonably acceptable to the Company
          to the affect that such legend is not

                                      19

 
          necessary in order to assure compliance with the Securities Act's
          registration provisions, the following legend:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS.
     THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD OR
     TRANSFERRED FOR VALUE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION OF THEM
     UNDER THE SECURITIES ACT OF 1933 AND/OR APPLICABLE STATE SECURITIES LAWS,
     OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER THAT SUCH
     REGISTRATION(S) IS (ARE) NOT REQUIRED THEREUNDER.

               (c)  The Purchaser may, at any time and from time to time, sell
          or otherwise transfer (x) any Purchaser Shares to any Affiliate of the
          Purchaser which agrees to be bound by the terms of this Agreement
          without any further limitation whatsoever and (y), subject to Section
          7.12(b), any Free Purchaser Shares to any Person; except that
          notwithstanding the foregoing, the Purchaser may only sell or
          otherwise transfer pursuant to clause (y) above Free Purchaser Shares
          (A) in a widely dispersed public distribution, (B) in a private
          placement in which no one party acquires the right to purchase in
          excess of 2% of the voting shares of the Company, (C) in an assignment
          to a single party (e.g. a broker or investment banker) for the purpose
                             - -                                                
          of conducting a widely dispersed public distribution on the
          transferor's behalf or (D) in any other manner permitted by the
          Federal Reserve Board.  For purposes of this paragraph (c),
          percentages of the Company's outstanding voting securities shall
          include shares issuable upon exercise or conversion of Series A
          Preferred stock, the Warrants or other similar securities owned by the
          Purchaser or its Affiliates but shall not include shares issuable upon
          exercise or conversion of convertible securities, options, warrants or
          other similar instruments owned by Persons who are not Affiliates of
          the Purchaser.

          7.13.  Governing Law; Jurisdiction.  THIS AGREEMENT SHALL BE GOVERNED
     BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
     NEW YORK.  THE COMPANY HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL
     COURTS LOCATED IN NEW YORK, NEW YORK, SHALL HAVE EXCLUSIVE JURISDICTION TO

     ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION,
     IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING
     OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT.
     THE COMPANY HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND
     OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF
     SUCH SUMMONS, COMPLAINT AND OTHER PROCESS MAY BE MADE BY REGISTERED OR

Agreement to be duly executed, all as of the day and year first above written.

                            (a Delaware Corporation)


     C.I.S. TECHNOLOGIES,INC., a Delaware corporation (the "Company"), hereby
certifies that BT Holdings (New York), Inc., a New York Corporation, its
successors and assigns, registered on the books of the Company maintained for
such purposes as the registered holder hereof (the "Holder"), for value
received, is entitled to purchase from the Company Five Hundred Thousand
(500,000) fully paid and non-assessable shares of Series A Participating
Convertible Preferred Stock of the Company, $0.01 par value ("Preferred
Shares"), at the purchase price of Three and 25/100 dollars ($3.25) per
Preferred Share (the "Exercise Price") (the number of Preferred Shares and
Exercise Price being subject to adjustment as hereinafter provided) upon the
terms and conditions herein provided.  Certain capitalized terms used herein
which are otherwise not defined are defined in the Stock and Warrant Purchase
Agreement of even date herewith (the "Agreement") to which Holder and the
Company are parties.

     1.   Exercise of Warrants.

          (a) Subject to subsection (b) of this Section 1, upon presentation and
     surrender of this Warrant Certificate, with the attached Purchase Form duly
     executed, at the principal office of the Company at Tulsa, Oklahoma, or at
     such other place as the Company may designate by notice to the Holder
     hereof, together with a certified or bank cashier's check payable to the
     order of the Company in the amount of the Exercise Price times the number
     of Preferred Shares being purchased, the Company shall deliver to the
     Holder hereof, as promptly as practicable, certificates representing the
     Preferred Shares being purchased.  This Warrant may be exercised in whole
     or in part; and, in case of exercise hereof in part only, the Company, upon
     surrender hereof, will deliver to the Holder a new Warrant Certificate or
     Warrant Certificates of like tenor entitling the Holder to purchase the
     number of Preferred Shares as to which this Warrant has not been exercised.

          (b) This Warrant must be exercised on or prior to November 23, 1997
     after which time it will be void and of no further force or effect.

     2.   Rights and Obligations of Warrant Holder.

          (a) The Holder of this Warrant Certificate shall not, by virtue
     hereof, be entitled to any rights of a shareholder in the Company, either
     at law or in equity; provided if any certificate representing the Preferred
     Shares is issued to the Holder hereof upon exercise of this Warrant, such
     Holder shall, for all purposes, be deemed to have become the holder of
     record of such Preferred Shares on the date on which this Warrant
     Certificate, together with a duly executed Purchase Form, was surrendered
     and payment of the Exercise Price was made, irrespective of the date of
     delivery of such Preferred Share certificate.  The rights of the Holder of
     this Warrant are limited to those expressed herein and the Holder of this
     Warrant, by its acceptance hereof, consents to and agrees to be bound by
     and to comply with all the provisions of this Warrant Certificate.  In
     addition, the Holder of this Warrant Certificate, by accepting the same,
     agrees that the Company may deem and treat the person in whose name this
     Warrant Certificate is registered on the books of the Company maintained
     for such purpose as the absolute, true and lawful owner for all purposes
     whatsoever, notwithstanding any notation of ownership or other writing
     thereon, and the Company shall not be affected by any notice to the
     contrary.

          (b) No Holder of this Warrant Certificate, as such, shall be entitled
     to vote or receive dividends or to be deemed the holder of Preferred Shares
     for any purpose, nor shall anything contained in this Warrant Certificate
     be construed to confer upon any Holder of this Warrant Certificate, as
     such, any of the rights of a shareholder of the Company or any right to
     vote, give or withhold consent to any action by the Company, whether upon
     any recapitalization, issue of stock, reclassification of stock,
     consolidation, merger, conveyance or otherwise, receive notice of meetings
     or other action affecting shareholders (except for notices provided for
     herein), receive dividends, subscription rights or otherwise, until this
     Warrant shall have become exercisable and been exercised and the Preferred
     Shares purchasable upon the exercise thereof shall have become deliverable
     as provided herein; provided that any such exercise on any date when the
     stock transfer books

 
     of the Company shall be closed shall constitute the person or persons in
     whose name or names the certificate or certificates for those Preferred
     Shares are to be issued as the record holder or holders thereof for all
     purposes at the opening of business on the next succeeding day on which
     such stock transfer books are open, and the Warrant surrendered shall not
     be deemed to have been exercised, in whole or in part as the case may be,
     until the next succeeding day on which the stock transfer books are open
     for the purpose of determining entitlement to dividends on the Company's
     Participating Convertible Series A Preferred stock.

     3.   Shares Underlying Warrants.  The Company covenants and agrees that all
Preferred Shares delivered upon exercise of this Warrant shall, upon delivery
and payment therefor, be duly and validly authorized and issued, fully-paid and
non-assessable, and free from all stamp-taxes, liens, and charges with respect
to the purchase thereof.  In addition, the Company agrees at all times to
reserve and keep available an authorized number of Preferred Shares sufficient
to permit the exercise in full of this Warrant.

     4.   Disposition of Warrants or Preferred Shares.  The Holder of this
Warrant Certificate and any transferee hereof or of the Preferred Shares
issuable upon the exercise of this Warrant Certificate, by their acceptance
hereof, hereby understand and agree that the Warrant, and the Preferred Shares
issuable upon the exercise hereof, have not been registered under either the
Securities Act of 1933 (the "Act") or applicable state securities laws (the
"State Acts") and shall not be sold, pledged, hypothecated, donated or otherwise
transferred (whether or not for consideration) except upon the issuance to the
Company of a favorable opinion of counsel and/or submission to the Company of
such evidence as may be satisfactory to counsel for the Company, in each such
case, to the effect that any such transfer shall not be in violation of the Act
and the State Acts.  It shall be a condition to the transfer of this Warrant
that any transferee thereof deliver to the Company its written agreement to
accept and be bound by all of the terms and conditions of this Warrant
Certificate.

     5.   Adjustments.

          (a) Stock Dividends.  If after the date hereof, the number of
              ---------------                                          
     outstanding shares of the Company's common stock, $.01 par value ("Common
     Shares"), is increased by a stock dividend payable in Common Shares or
     Preferred Shares or by a split-up of Common Shares, then, on the day
     following the date fixed for the determination of holders of Common Shares
     entitled to receive such stock dividend or split-up, the number of
     Preferred Shares issuable on exercise of the Warrants shall be increased in
     proportion to such increase in outstanding Common Shares or Preferred
     Shares and the then applicable Exercise Price shall be correspondingly
     decreased.

          (b) Aggregation of Shares.  If after the date hereof, the number of
              ---------------------                                          
     outstanding Common Shares is decreased by a combination or reclassification
     of Common Shares, then, after the effective date of such combination or
     reclassification, the number of Preferred Shares issuable on exercise of
     the Warrants shall be decreased in proportion to such decrease in
     outstanding Common Shares and the then applicable Exercise Price shall be
     correspondingly increased.

          (c) Special Stock Dividend.  If after the date hereof, shares of any
              ----------------------                                          
     class of the Company (other than Common Shares) are issued by way of a
     stock dividend on outstanding Common Shares then, commencing with the day
     following the date fixed for the determination of holders of Common Shares
     entitled to receive such stock dividend, in addition to any Preferred
     Shares receivable upon exercise of the Warrants, the Holder shall, upon
     such exercise of the Warrants, be entitled to receive, as nearly as
     practicable, the same number of shares of dividend stock, plus any shares
     issued upon any subsequent change, replacement, subdivision or combination
     thereof to which the holders would have been entitled had their Warrants
     been exercised immediately prior to such stock dividend.

          (d)  Issuance of Shares Below Market.  If on a date after the date
               -------------------------------                              
     hereof ("New Issue") the Company issues and sells Common Shares, Preferred
     Shares, or a combination thereof at a price per share less than the market
     price per Common Share (determined as provided in the following paragraph)
     on the New Issue Date, the Exercise Price in effect at the opening of
     business on the day following such issuance and sale shall be adjusted by
     multiplying such Exercise Price by a fraction of which (i) the numerator
     shall be the aggregate number of Common Shares and Preferred Shares
     outstanding at the close of business on the New Issue Date plus the number
     of Common Shares which the aggregate of the offering price of the total
     number of Common Shares, Preferred Shares, or combination thereof so issued
     and sold would purchase at such current market price, and (ii) the
     denominator shall be the aggregate number of Common Shares and Preferred
     Shares outstanding at the close of business on the New Issue Date plus the
     number of Common Shares, Preferred Shares, or combination thereof so
     offered and sold, such adjustment to become effective immediately after the
     opening of business on the day following the date, and contingent upon the
     actual occurrence, of such issuance and sale.

          For purposes of the preceding paragraph, the "market price per Common
     Share" shall be the average of the daily closing prices for any period of
     five to ten consecutive business days selected by the Company commencing
     not more than 20 business days before the day in question.  "Business day"
     means any Monday, Tuesday, Wednesday, Thursday and Friday other than any
     day on which securities are not traded on the principal exchange or
     principal market through which Common Shares are traded.  The closing price
     for each such day shall be the last reported sales price, regular way, or,
     in

                                       2

 
     case no such reported sale takes place on such day, the average of the
     reported closing bid and asked prices, regular way, in either case on the
     New York Stock Exchange, Inc. or, if the Common Shares are not listed or
     admitted to trading on such Exchange, on the principal national securities
     exchange on which the Common Shares are listed or admitted to trading or,
     if not listed or admitted to trading on any national securities exchange,
     on the NASDAQ Stock Market, Inc. National Market or, if the Common Shares
     are not listed or admitted to trading on any national securities exchange
     or quoted on such National Market, the fair market value as determined in
     good faith by the board of directors of the Company, whose determination
     shall, absent demonstrable error, be conclusive.

          (e) Reorganization.  If after the date hereof any capital
              --------------                                       
     reorganization or reclassification of the Common Shares, or consolidation
     or merger of the Company with another Corporation, or the sale of all or
     substantially all of its assets to another corporation shall be effected,
     then, as a condition of such reorganization, reclassification,
     consolidation, merger or sale, lawful and fair provisions shall be made
     whereby the Holders shall thereafter have the right to purchase and receive
     in lieu of the Preferred Shares immediately theretofore purchasable and
     receivable upon the exercise of the rights represented hereby, such shares
     of stock, securities or assets as may be issued or payable with respect to
     or in exchange for a number of outstanding Common Shares equal to the
     number of Preferred Shares immediately theretofore purchasable and
     receivable upon the exercise of the rights represented by the Warrants had
     such reorganization, reclassification, consolidation, merger or sale not
     taken place and in any such case appropriate provisions shall be made with
     respect to the rights and interests of the Holders to the end that the
     provisions hereof (including, without limitation, provisions for
     adjustments of the Exercise Price and the number of Preferred Shares
     purchasable upon the exercise of the Warrants) shall thereafter be
     applicable as nearly as may be in relation to any share of stock,
     securities, or assets thereafter deliverable upon the exercise hereof.  The
     Company shall not effect any such consolidation, merger or sale unless
     prior to the consummation thereof the successor corporation (if other than
     the Company) resulting from such consolidation or merger, or the
     corporation purchasing such assets, shall assume by written instrument
     executed and delivered to the Holders the obligation to deliver to the
     Holders such shares of stock, securities or assets as, in accordance with
     the foregoing provisions, such holders may be entitled to purchase.

          (f) Notice to Warrant Holders of Adjustment.  Whenever the number of
              ---------------------------------------                         
     Preferred Shares purchasable or the Exercise Price hereunder is adjusted as
     herein provided, the Company shall cause to be mailed to the Holder in
     accordance with the provisions of this Section a notice (i) stating that
     the number of Preferred Shares purchasable upon exercise or the Exercise
     Price of this Warrant has been adjusted, (ii) setting forth the adjusted
     number of Preferred Shares purchasable upon the exercise of this Warrant or
     the adjusted Exercise Price, and (iii) showing in reasonable detail the
     computations and the facts, including the amount of consideration received
     or deemed to have been received by the Company, upon which such adjustments
     are based.

     6.   Loss or Destruction.  Upon receipt of evidence satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant
Certificate and, in the case of any such loss, theft or destruction, upon
delivery of an indemnity agreement or bond satisfactory in form, substance and
amount to the Company or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant Certificate, the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant Certificate of like tenor.

     7.   Survival.  The various rights and obligations of the Holder hereof as
set forth herein shall survive the exercise of the Warrants represented hereby
and the surrender of this Warrant Certificate.

     8.   Notices.  Whenever any notice, payment of any purchase price, or other
communication is required to be given or delivered under the terms of this
Warrant, it shall be in writing and delivered by hand delivery or United States
registered or certified mail, return receipt requested, postage prepaid, and
will be deemed to have been given or delivered on the date such notice, purchase
price or other communication is so delivered or posted, as the case may be; and,
if to the Company, it will be addressed as follows:

               C.I.S. Technologies, Inc.

and if to the Holder, it will be addressed to the registered Holder at his

GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE
OF NEW YORK.  THE COMPANY HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL
COURTS LOCATED IN NEW YORK, NEW YORK, SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR
