                                                           _______________, 1995



         Dear Shareholder of Integrated Medical Systems, Inc.:

                   You are cordially invited to attend a Special Meeting of
         Shareholders of Integrated Medical Systems, Inc., a Colorado
         corporation (the "Company"), which will be held on ______, _____, 1995,
         at ______________, commencing at  ___m. local time.  At this meeting
         you will be asked to consider and vote upon the approval and adoption
         of an Agreement and Plan of Merger dated August 2, 1995 (the "Merger
         Agreement"), providing for the merger (the "Merger") of a wholly-owned
         subsidiary of Eli Lilly and Company, an Indiana corporation ("Lilly"),
         with and into the Company.  As a result of the Merger, the Company will
         become a subsidiary of Lilly, and Company shareholders will receive
         cash or other securities as described below.  The enclosed Proxy
         Statement-Prospectus describes the proposed Merger in detail and should
         be read carefully in its entirety.

                   The Merger is required to be approved by the affirmative vote
         of the holders of at least two-thirds of the outstanding shares of
         common stock, Series B Preferred Stock ("Series B Stock") and Series C
         Preferred Stock ("Series C Stock"), voting together as a single class,
         and the affirmative vote of at least two-thirds of the outstanding
         shares of each of the Series B Stock and the Series C Stock, each
         voting separately as a class.  As of ___________, 1995, the directors
         of the Company and their affiliates (other than Lilly or any wholly-
         owned subsidiary of Lilly) owned an aggregate of 3,337,795 shares of
         Company common stock representing 51% of the Company common stock
         entitled to vote on the Merger and 1,581,562 shares of Series B Stock
         representing 79% of the Series B Stock entitled to vote on the Merger.
         All of these shareholders have agreed with Lilly to vote the shares of
         Company common stock or Series B Stock owned by them (or acquired in
         the future) in favor of the Merger.  In addition, Lilly, through its
         wholly-owned subsidiaries, owns 160,200 shares of Company common stock
         and all of the Series C Stock entitled to vote on the Merger and
         intends to vote all of such shares in favor of the Merger.  The shares
         of Company common stock, Series B Stock and Series C Stock collectively
         owned by these shareholders and Lilly represent approximately 70% of
         the Company common stock, Series B Stock and Series C Stock entitled to
         vote as a class on the Merger.  Thus, upon the vote of these
         shareholders in accordance with such agreements, shareholder approval
         of the Merger is assured.

                   As a result of the Merger,

              (a)  each issued and outstanding share of common stock of the
                   Company (other than dissenting shares or shares owned by
                   Lilly or a subsidiary of Lilly) will be converted into the
                   right to receive, at the holder's election, either $8.00 in
                   cash, without interest, or one share of Series D Preferred
                   Stock ("Series D Stock"), a newly created class of preferred
                   stock of the Company which will have the preferences,
                   limitations and relative rights described in the enclosed
                   Proxy Statement-Prospectus and in the Articles of Merger of
                   the surviving corporation, and

              (b)  each issued and outstanding share of Series B Stock of the
                   Company (other than dissenting shares) will, at the holder's
                   election, (i) convert into the right to receive either (A)
                   $5.33 per share in cash, without interest, plus an amount, in
                   cash, without interest, equal to the amount of all accrued
                   and unpaid dividends on such a share of Series B Stock

 
                   to the effective date of the Merger, or (B) two-thirds of a
                   share of Series D Stock plus an amount, in cash, without
                   interest, equal to the amount of all accrued and unpaid
                   dividends on such a share of Series B Stock to the effective
                   date of the Merger, or (ii) will remain outstanding (with the
                   amended preferences, limitations and relative rights
                   described in the Articles of Incorporation of the surviving
                   corporation), and

              (c)  each issued and outstanding share of Series C Stock of the
                   Company (other than dissenting shares) will be converted into
                   one share of common stock of the surviving corporation.

                   Company shareholders have dissenters' rights with respect to
         their shares and must closely follow the procedures set forth in the
         Proxy Statement-Prospectus in order to properly perfect such rights.

                   The Board of Directors has received the opinion of the
         investment banking firm of Smith Barney Inc. to the effect that, based
         on the matters described therein, the consideration to be offered in
         the Merger to IMS shareholders (other than Lilly and its subsidiaries)
         is fair to such shareholders from a financial point of view.  The
         opinion is attached as Appendix C to the Proxy Statement-Prospectus.

                   Based on certain factors described in the Proxy Statement-
         Prospectus, the Board of Directors of the Company has determined that
         the Merger is fair and in the best interests of the Company and its
         shareholders.  Accordingly, the Board of Directors has approved the
         Merger Agreement and the Merger and recommends that the shareholders
         vote for adoption and approval of the Merger Agreement and the Merger.
         Each of the Directors has agreed with Lilly to so vote shares held by
         the director and, in certain cases, members of his immediate family.

                   In addition, approval of the Merger by the Company's
         shareholders also includes approval of an amendment to the Company's
         1994 Stock Option Plan (the "Plan") in order to increase the number of
         shares of common stock authorized to be issued under the Plan from
         400,000 shares to 838,600 shares, which equals the total number of
         shares subject to options previously granted under the Plan.  Approval
         of the Merger also includes approval of an amendment to the Company's
         articles of incorporation, effective upon consummation of the Merger,
         which will, among other things, eliminate the voting rights of the
         Series B Stock other than as required by Colorado law and make the
         Series B Stock parity stock with the Series D Stock upon liquidation,
         dissolution or winding-up of IMS.

                   Please complete, sign and mail promptly the enclosed Proxy,
         whether or not you intend to be present in person at the Special
         Meeting.  If you attend the Special Meeting, you may vote your shares
         in person even if you have previously submitted a Proxy.

                   DO NOT SEND IN YOUR SHARE CERTIFICATES WITH YOUR PROXY.

                                        Respectfully,

Plan to increase the number of shares available under such plan from 400,000
shares of Company Common Stock to 838,600 shares of Company Common Stock, which
equals the total number of shares subject to options previously granted under
the Plan.

 
         Approval of the Merger by IMS shareholders will also include approval
of an amendment to the Articles of Incorporation of IMS, effective upon
consummation of the Merger, which will, among other things, eliminate the voting

Stock upon the liquidation, dissolution or winding-up of IMS.

                                    SUMMARY

           The following is a brief summary of certain information contained
     elsewhere in this Proxy Statement-Prospectus.  This summary is qualified in
     its entirety by the more detailed information contained in this Proxy
     Statement-Prospectus, in its Appendices and in the documents referred to
     herein, to which reference is made for a more complete statement of the
     matters discussed below.

     THE COMPANIES

          Integrated Medical Systems, Inc.

           Integrated Medical Systems, Inc. ("IMS" or the "Company") was founded
     in 1985.  IMS develops and operates computerized medical communications
     networks that link participants in the healthcare delivery and payment
     systems enabling such participants to convert routine and specialized
     messages from manual to automated media and to provide a practical means
     for providers and payers to integrate the services they provide.
     Healthcare, and especially the individual physician's practice of medicine,
     generates prolific requirements for multi-location, multi-system clinical,
     financial and administrative communication and information transfer and
     management.  IMS believes that it is the nation's leading provider of
     physician-focused, multi-participant, multi-media, bi-directional automated
     healthcare communications through a common user interface, in terms of
     total number of transactions, variety of transactions, number of
     physicians, number and variety of  interfaced host healthcare information
     systems, number of institutions (hospitals, managed care plans, clinical
     laboratories, ancillary care providers and healthcare information and
     administrative services) and number of operational networks and markets
     served.

           The mailing address and telephone number of IMS's principal executive
     offices are 15000 West 6th Avenue, Suite 400, Golden, Colorado 80401, (303)
     279-6116.  See "BUSINESS OF IMS."

          Eli Lilly and Company

           Eli Lilly and Company ("Lilly") was incorporated in 1901 under the
     laws of the state of Indiana to succeed to the drug manufacturing business
     founded in Indianapolis, Indiana, in 1876 by Colonel Eli Lilly.  Lilly is
     engaged in the discovery, development, manufacture, and sale of products
     and the provision of services in one industry segment--Life Sciences.
     Lilly's principal products are human pharmaceuticals and animal health
     products.  Products are manufactured or distributed through owned or leased
     facilities in the United States, Puerto Rico, and 26 other countries, in 19
     of which Lilly owns or has an interest in manufacturing facilities.  Its
     products are sold in approximately 117 countries.  Through its PCS Health
     Systems, Inc. subsidiary ("PCS"), Lilly also provides pharmacy benefit
     management services in the United States.

           Most of Lilly's products were discovered or developed through Lilly's
     research and development activities, and the success of Lilly's business
     depends to a great extent on the introduction of new products resulting
     from these research and development activities.  Research efforts are
     primarily directed toward the discovery of products to diagnose and treat
     diseases in human beings and animals and to increase the efficiency of
     animal food production.

           Trans-IMS Corporation, a Colorado corporation and a wholly-owned
     subsidiary of Lilly ("Subsidiary"), is a corporation recently organized in
     connection with the Merger and has not conducted any other business.

           The principal executive offices of Lilly and Subsidiary are located
     at Lilly Corporate Center, Indianapolis, Indiana 46285, and their telephone
     number at that location is (317) 276-2000.

 
     THE SPECIAL MEETING

          Time, Date and Place

           The special meeting of IMS shareholders (the "Special Meeting") will
     be held on ________, 1995, at _____ A.M. local time, at
     __________________________________.

          Purpose of the Meeting

           At the Special Meeting, the IMS shareholders will be asked to
     consider and vote upon the proposed merger (the "Merger") of Subsidiary
     into IMS.  The Merger will result in IMS becoming a subsidiary of Lilly,
     with all of IMS's outstanding voting stock being owned by Lilly and all of
     IMS's other shareholders owning non-voting Series D Preferred Stock and
     Series B Preferred Stock.

          Record Date and Outstanding Shares

           Holders of record (the "Record Holders") of shares of (i) common
     stock, without par value, of IMS (the "Company Common Stock"), (ii) Series
     B Preferred Stock, par value $1.00 per share, of IMS (the "Series B
     Preferred Stock") and (iii) Series C Preferred Stock, par value $1.00 per
     share, of IMS (the "Series C Preferred Stock") at the close of business on
     ________, 1995 (the "Record Date"), will be entitled to notice of and to
     vote at the Special Meeting.  Each issued and outstanding share of Company
     Common Stock, Series B Preferred Stock and Series C Preferred Stock is
     entitled to one vote per share with respect to the Merger.  On the Record
     Date, there were 6,584,002 shares of Company Common Stock issued and
     outstanding held by approximately 197 holders, 2,000,000 shares of Series B
     Preferred Stock issued and outstanding held by approximately 23 holders and
     3,000,000 shares of Series C Preferred Stock issued and outstanding all of
     which were held by wholly-owned subsidiaries of Lilly.

          Required Vote

           Under Colorado law and the Articles of Incorporation of IMS, the
     affirmative vote of two-thirds of the outstanding shares of Company Common
     Stock, Series B Preferred Stock and Series C Preferred Stock, voting
     together as a single class, and the affirmative vote of two-thirds of the
     outstanding shares of each of the Series B Preferred Stock and the Series C
     Preferred Stock, each voting separately as a class, are required to approve
     the Merger.  In addition, pursuant to the Merger Agreement, it is a
     condition to the consummation of the Merger that the Merger be approved by
     the affirmative vote of shares representing at least a majority of the
     voting power of the outstanding shares of Company Common Stock and Series B
     Preferred Stock that are not owned by Lilly or its subsidiaries.

           As of the Record Date, the directors of IMS and their affiliates
     (other than Lilly or any subsidiary of Lilly) owned an aggregate of
     3,337,795 shares of Company Common Stock, representing approximately 51% of
     the Company Common Stock entitled to vote on the Merger, and 1,581,562
     shares of Series B Preferred Stock, representing 79% of the Series B
     Preferred Stock entitled to vote on the Merger.  All of these shareholders
     have agreed with Lilly to vote their shares in favor of the Merger.  In
     addition, Lilly, through its wholly-owned subsidiaries, owns 160,200 shares
     of Company Common Stock and all of the Series C Preferred Stock and will
     vote those shares in favor of the Merger.  The shares of Company Common
     Stock, Series B Preferred Stock and Series C Preferred Stock collectively
     owned by these shareholders and Lilly represent approximately 70% of the
     Company Common Stock, Series B Preferred Stock and Series C Preferred Stock
     entitled to vote as a class on the Merger.  Thus, upon the vote of these
     shareholders in accordance with such agreements, shareholder approval of
     the Merger is assured.

                                       2

 
     THE MERGER

          Conversion of Shares of Company Common Stock, Series B Preferred Stock
     and Series C Preferred Stock

           Pursuant to the Merger, (i) each outstanding share of Company Common
     Stock (other than shares held by IMS as treasury shares, shares owned by
     Lilly or any subsidiary of Lilly, or shares as to which dissenters' rights
     have been perfected under Colorado law) will be converted into, at the
     holder's election, either (a) $8.00 in cash, without interest, or (b) one
     share of Series D Preferred Stock, (ii) each outstanding share of Series B
     Preferred Stock (other than shares as to which dissenters' rights have been
     perfected under Colorado law) will either (a) be converted into, at the
     holder's election, either (1) $5.33 in cash, without interest, plus an
     amount, in cash, without interest, equal to the amount of all accrued and
     unpaid dividends on such share of Series B Preferred Stock to the effective
     date of the Merger or (2) two-thirds of a share of Series D Preferred Stock
     plus an amount, in cash, without interest, equal to the amount of all
     accrued and unpaid dividends on such share of Series B Preferred Stock to
     the effective date of the Merger or (b) remain outstanding (with the
     amended preferences, limitations and rights set forth in the Articles of
     Incorporation of the surviving corporation) and (iii) each outstanding
     share of Series C Preferred Stock of the Company will be converted into one
     share of common stock of the surviving corporation.  The cash and Series D
     Preferred Stock to be issued in connection with the Merger is referred to
     as the "Merger Consideration".

           No fractional shares of Series D Preferred Stock will be issued, but,
     in lieu thereof, cash payments will be made to each holder of Series B
     Preferred Stock in respect of any fractional share that would otherwise be
     issuable to such holder (after aggregating all of the shares of Series D
     Preferred Stock to be issued to such holder) in an amount equal to such
     fractional part of a share of Series D Preferred Stock multiplied by $8.00.
     No such holder shall be entitled to dividends, voting rights or any other
     shareholder right in respect of any fractional share.

          Election; Form of Election Procedures

           Subject to the election procedures set forth below, each record
     holder immediately prior to the Effective Date of the Merger of shares of
     Company Common Stock or Series B Preferred Stock (other than Lilly or any
     subsidiary of Lilly) will be entitled (i) to elect to receive cash for any
     or all of such shares (a "Cash Election"), or (ii) to elect to receive
     Series D Preferred Stock for any or all of such shares (a "Stock
     Election").  In addition, each record holder immediately prior to the
     Effective Date of shares of Series B Preferred Stock will be entitled to
     elect to retain those shares of Series B Preferred Stock, as amended by the
     Articles of Merger (an "Election to Retain Series B Preferred Stock").  ALL
     SUCH ELECTIONS SHALL BE MADE ON A FORM OF ELECTION (A "FORM OF ELECTION")
     THAT WILL BE MAILED SEPARATELY TO SHAREHOLDERS OF RECORD ON THE EFFECTIVE
     DATE FOLLOWING THE MERGER.  To be effective, a Form of Election must be
     properly completed, signed and submitted to Citibank, N.A., as exchange
     agent (the "Exchange Agent"), and (except if an Election to Retain Series B
     Preferred Stock is made or deemed to have been made) accompanied by the
     certificates representing the shares of Company Common Stock or Series B
     Preferred Stock as to which the election is being made (or by an
     appropriate guarantee of delivery of such certificates by a commercial bank
     or trust company in the United States or a member of a registered national
     securities exchange or the National Association of Securities Dealers,
     Inc.).  All duly completed Forms of Election must be received by the
     Exchange Agent no later than 5:00 p.m., New York City Time, on
     __________________ (the "Election Deadline").  A HOLDER OF COMPANY COMMON
     STOCK OR SERIES B PREFERRED STOCK WHO DOES NOT SUBMIT A PROPERLY COMPLETED
     AND SIGNED FORM OF ELECTION WHICH IS RECEIVED BY THE EXCHANGE AGENT PRIOR
     TO THE ELECTION DEADLINE SHALL BE DEEMED TO HAVE MADE A CASH ELECTION, IN
     THE CASE OF A HOLDER OF COMPANY COMMON STOCK, AND AN ELECTION TO RETAIN
     SERIES B PREFERRED STOCK, IN THE CASE OF A HOLDER OF SERIES B PREFERRED
     STOCK.  An election may be revoked, but

                                       3

 
     only by written notice received by the Exchange Agent prior to the Election
     Deadline.  See "THE MERGER AGREEMENT - Form of Election Procedures."

           SHAREHOLDERS SHOULD NOT SEND IN ANY SHARE CERTIFICATES WITH THEIR
     PROXY CARDS.

          Effect of the Merger on Company Options and Company Warrants

           Each holder of outstanding options to purchase Company Common Stock
     (the "Company Options") on the Effective Date will have the right,
     immediately following the Merger, to elect to have such Company Options
     converted, in whole or in part, into (i) the right to receive $8.00 in
     cash, without interest, for each share of Company Common Stock for which
     such Company Option was exercisable as of the Effective Date (except that
     in lieu of paying the exercise price of such Company Option, the holder
     thereof may elect to net the amount of the exercise price against and to
     that extent reduce the $8.00 otherwise receivable), or (ii) the right to
     purchase, for the same exercise price, one share of Series D Preferred
     Stock for each share of Company Common Stock for which such Company Option
     was exercisable as of the Effective Date or (iii) fully vested options to
     acquire shares of Common Stock of Lilly ("Lilly Common Stock") under the
     1994 Lilly Stock Plan registered on Form S-8 ("Lilly Options").  Any
     election pursuant to clause (ii) above must be for a whole number of shares
     of Series D Preferred Stock.

           Each holder of outstanding warrants to purchase Company Common Stock
     (the "Company Warrants") on the Effective Date (other than any warrants
     owned by Lilly or any of its subsidiaries) will have the right to elect to
     have such Company Warrants converted into (i) the right to receive $8.00 in
     cash, without interest, for each share of Company Common Stock for which
     such Company Warrant was exercisable as of the Effective Date (except that
     in lieu of paying the exercise price of such Company Warrant, the holder
     thereof may elect to net the amount of the exercise price against and to
     that extent reduce the $8.00 otherwise receivable) or (ii) the right to
     purchase, for the same exercise price, one share of Series D Preferred
     Stock for each share of Company Common Stock for which such Company Warrant
     was exercisable as of the Effective Date.  Each warrant to purchase Series
     C Preferred Stock owned by Lilly or any of its subsidiaries will, on the
     Effective Date, be converted into the right to purchase one share of common
     stock of the surviving corporation for each share for which such warrant
     was exercisable as of the Effective Date.

           A Form of Election for use by holders of Company Options and Company
     Warrants will be mailed separately to the holders thereof following the
     consummation of the Merger.  To be effective, a Form of Election must be
     properly completed, signed and received by the Exchange Agent by the
     Election Deadline.  HOLDERS OF COMPANY OPTIONS OR COMPANY WARRANTS WHO DO
     NOT PROPERLY COMPLETE AND RETURN A FORM OF ELECTION BY THE ELECTION
     DEADLINE WILL BE DEEMED TO HAVE ELECTED TO RECEIVE THE LILLY OPTIONS, IN
     THE CASE OF A COMPANY OPTION, OR THE RIGHT TO PURCHASE SHARES OF SERIES D
     PREFERRED STOCK, IN THE CASE OF COMPANY WARRANTS.  See "THE MERGER
     AGREEMENT - Effect of the Merger on Company Options and Company Warrants."

          Recommendation of IMS's Board of Directors

           THE BOARD OF DIRECTORS OF IMS (WITH ONE DIRECTOR ABSENT) HAS
     UNANIMOUSLY DETERMINED THAT THE PROPOSED MERGER IS FAIR AND REASONABLE AND
     IN THE BEST INTERESTS OF IMS AND ITS SHAREHOLDERS (OTHER THAN LILLY AND ITS
     SUBSIDIARIES) AND RECOMMENDS APPROVAL AND ADOPTION OF THE MERGER AGREEMENT
     BY IMS SHAREHOLDERS (EXCEPT THAT THE TWO DIRECTORS WHO ARE AFFILIATED WITH
     LILLY ABSTAINED FROM THE BOARD'S DELIBERATIONS AND VOTE).  For a discussion
     of the factors considered by IMS's Board of Directors in approving the
     Merger, see

                                       4

 
     "SPECIAL FACTORS TO BE CONSIDERED - Recommendation of the IMS Board of
     Directors; Fairness of the Merger."

          Opinion of Financial Advisor

           Smith Barney Inc. ("Smith Barney") has delivered its written opinion
     dated August 2, 1995 to the effect that the consideration to be offered to
     IMS's shareholders (other than Lilly and its subsidiaries) in the Merger
     was fair from a financial point of view as of the date of such opinion.  A
     copy of Smith Barney's opinion, which sets forth the assumptions made,
     procedures followed, matters considered, limitations on and the scope of
     the review by Smith Barney in rendering its opinion, is attached to this
     Proxy Statement-Prospectus as Appendix C and should be read carefully in
     its entirety.  See "SPECIAL FACTORS TO BE CONSIDERED - Opinion of Financial
     Advisor."

          Prior Relationship/Agreements of the Parties

           Lilly, through PCS, has been a shareholder of IMS since November
     1994, when Lilly acquired the PCS pharmacy benefit management services
     business of McKesson Corporation ("McKesson").  As a result of that
     acquisition, Lilly, through PCS, has owned, or had the right to acquire,
     about 28% of the Company Common Stock on a fully-diluted basis.

           By acquiring PCS, Lilly also acquired various contract rights that
     are described below.  In some instances, IMS has disputed whether those
     rights continue to exist and, if so, the extent of those rights.  Under the
     McKesson Sponsorship Agreement, PCS has claimed various rights to utilize
     IMS Networks to send and receive information between IMS Network Sites and
     PCS clients, and to link IMS Networks to PCS's transaction processing and
     data base management infrastructure to send and receive information in
     support of a variety of services.  In addition, under this Agreement, IMS
     has agreed that it will not introduce "Prescription Benefit Management
     Services" without the approval and except on terms acceptable to PCS.  See
     "SPECIAL FACTORS TO BE CONSIDERED - Prior Agreements/Relationship of the
     Parties-McKesson Sponsorship Agreement."

           Under the McKesson Stockholder's Rights Agreement, PCS has claimed
     various rights, including the right to elect two directors of IMS, rights
     of access for "McKesson Products Lines" to the physicians who are
     "Subscribers" to IMS Networks, and rights of approval over agreements for
     the operation of an IMS Network with any entity engaged in a business
     defined as a "McKesson Product Line."

           In addition, under this Agreement, PCS has claimed a right of first
     offer to purchase any "New Securities" that IMS proposes to sell, subject
     to certain exceptions, and a right to approve any prospective purchasers of
     "New Securities" who are engaged in any of the businesses defined as
     "McKesson Product Lines."  See "SPECIAL FACTORS TO BE CONSIDERED - Prior
     Agreements/Relationship of the Parties-McKesson Stockholder's Rights
     Agreement."

           Lilly has also loaned to IMS an aggregate of $5 million and has
     agreed to continue to loan to IMS from time to time at IMS's request
     additional funds as required to fund the then current cash requirements of
     IMS but not to exceed $1.5 million per month.  Each loan is due and payable
     upon the earlier of any breach of the Merger Agreement by IMS (subject to
     certain rights of IMS to cure such breach) or July 1, 1996 with interest at
     the annual rate of 10%.  Each loan is subordinated to all IMS indebtedness
     outstanding on the date of such loan and is secured by a pledge of most of
     the assets of IMS, including shares of subsidiaries.

                                       5

 
          Put/Call Agreements

           Lilly will offer each holder of Company Common Stock, Series B
     Preferred Stock, Company Options or Company Warrants (a "Holder") the
     opportunity to enter into a Put/Call Agreement that would apply to any or
     all of the Holder's shares of Series D Preferred Stock as the Holder may
     elect (the "Subject Shares").

           Under a Put/Call Agreement, a Holder will have the right to require
     Lilly to purchase any or all of the Holder's Subject Shares during each of
     two Put Periods at a price of $8.00 per share, plus any unpaid dividends
     accrued to the purchase date (the "Purchase Price").  The initial Put
     Period shall be a period of at least 10 business days beginning on the
     first anniversary of the Merger; the second Put Period shall be a period of
     at least 10 business days beginning approximately 30 months after the
     Merger.

           Under a Put/Call Agreement, Lilly will have the right to require a
     Holder to sell any or all of the Holder's Subject Shares to Lilly at the
     Purchase Price in whole at any time or in part from time to time after the
     third anniversary of the Merger.

           The stock certificates representing the Subject Shares will bear a
     restrictive legend and must be deposited into an escrow accompanied by an
     undated stock power endorsed in blank relating to the Subject Shares.  The
     Holder will have the right to sell, assign, donate, pledge or otherwise
     transfer or encumber any or all of the Subject Shares and any related
     rights and obligations under the Put/Call Agreement only with Lilly's prior
     written consent, which will be granted under certain specified conditions.
     See "PUT/CALL AGREEMENTS."

          Amendment to Employee Stock Option Plan

           Approval of the Merger by IMS shareholders will include approval of
     an amendment to the Integrated Medical Systems, Inc. 1994 Employee Stock
     Option Plan (the "1994 Employee Stock Option Plan") to increase the number
     of shares available under such plan from 400,000 shares of Company Common
     Stock to 838,600 shares of Company Common Stock, which equals the total
     number of shares subject to options previously granted under the Plan.  See
     "AMENDMENT TO THE IMS 1994 EMPLOYEE STOCK OPTION PLAN."

          Amendment to Articles of Incorporation

           Approval of the Merger by IMS shareholders will also include approval
     of an amendment to the Articles of Incorporation of IMS, effective upon
     consummation of the Merger, which will, among other things, eliminate the
     voting rights of the Series B Preferred Stock other than as required by
     Colorado law and make the Series B Preferred Stock parity stock with Series
     D Preferred Stock upon the liquidation, dissolution or winding-up of IMS.
     See "AMENDMENT TO THE ARTICLES OF INCORPORATION OF IMS."  For a description
     of the amended preferences, limitations and relative rights of the Series B
     Preferred Stock following the Merger, see "DESCRIPTION OF CAPITAL STOCK OF
     IMS - Series B Preferred Stock."

          Conditions to the Merger

           The obligations of Lilly, Subsidiary and IMS to consummate the Merger
     are subject to the satisfaction of certain conditions, including approval
     of the Merger by IMS's shareholders at the Special Meeting.  Other
     conditions to each party's obligations to consummate the Merger may be
     waived by such party, subject to applicable law and certain limitations
     imposed by the Merger Agreement.  Neither Lilly

                                       6

 
     nor IMS presently intends to waive any such conditions although each of
     them reserves the right to do so.  See "THE MERGER AGREEMENT - Conditions
     to the Merger."

          Governmental and Regulatory Approvals

           In connection with prior exercises of Warrants to purchase Series C
     Preferred Stock, Lilly filed a Notification with the Federal Trade
     Commission and the Department of Justice pursuant to the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976, as amended (the "HSR Act") on February
     27, 1995, seeking clearance to acquire 50% or more of the voting stock of
     IMS.  No second request for additional information was received and the
     mandatory waiting period expired on March 29, 1995.  As a result, no
     further action is required under the HSR Act in connection with the Merger
     provided that the Merger is completed by March 29, 1996.  See "SPECIAL
     FACTORS TO BE CONSIDERED - Governmental and Regulatory Approvals."

          Effective Date

           The Merger will become effective at such time as the Articles of
     Merger setting forth the principal terms of the Merger provided for in the
     Merger Agreement is duly filed with the Colorado Secretary of State in
     accordance with Colorado law (the "Effective Date").  Under the Merger
     Agreement, the required filing is expected to be made as soon as
     practicable after the satisfaction or waiver of all conditions to the
     Merger, including the approval of the Merger by IMS shareholders at the
     Special Meeting.  It is anticipated that if the Merger is approved at the
     Special Meeting and all other conditions to the Merger have been fulfilled
     or waived, the Effective Date will occur on the date of the Special Meeting
     or as soon as practicable thereafter.  See "THE MERGER AGREEMENT - The
     Merger."

          Termination

           The Merger Agreement may be terminated at any time prior to the
     Effective Date:  (i) by mutual consent of Lilly, Subsidiary and IMS; (ii)
     by Lilly and Subsidiary, or by IMS, respectively, if, at or before the
     Effective Date, any condition set forth in the Merger Agreement for the
     benefit of Lilly and Subsidiary or IMS, respectively, will not have been
     timely met and such failure will not have been cured or eliminated, or by
     its nature cannot be cured or eliminated; (iii) by Lilly and Subsidiary or
     by IMS if the closing of the Merger (the "Closing") will not have occurred
     on or before December 31, 1995, or such later date as may have been agreed
     upon by the parties or as is provided for in the Merger Agreement in
     connection with Lilly's right to delay or suspend the effectiveness of the
     Registration Statement; or (iv) by Lilly and Subsidiary or by IMS in
     certain other specific circumstances.  Upon the termination of the Merger
     Agreement under certain specific circumstances, IMS or Lilly may be
     required to pay the other a $4 million termination fee.  See "THE MERGER
     AGREEMENT - Termination" and "- Liability of the Parties Upon Termination."

          Dissenters' Rights

           Record Holders who object to the Merger may, under certain
     circumstances and by following prescribed statutory procedures, receive
     cash for their shares of Company Common Stock or Series B Preferred Stock
     in lieu of the consideration described above.  The failure of a dissenting
     shareholder to follow such procedures, which are described more fully
     elsewhere in this Proxy Statement-Prospectus, may result in termination or
     waiver of such shareholder's rights as a dissenter.  See "RIGHTS OF
     DISSENTING SHAREHOLDERS."

                                       7

 
          Accounting Treatment

           It is expected that the Merger will be treated as a "purchase" for
     financial accounting purposes in accordance with generally accepted
     accounting principles ("GAAP").  See "SPECIAL FACTORS TO BE CONSIDERED -
     Accounting Treatment of the Merger."

          Certain Federal Income Tax Consequences of the Merger

           A holder of Company Common Stock or Series B Preferred Stock (or
     Company Warrants) who elects to receive cash in exchange for all or a
     portion of his or her IMS stock (or warrants) will recognize taxable gain
     or loss for federal income tax purposes with respect to those shares (or
     warrants) in an amount equal to the difference between (a) the amount of
     the cash received by such holder and (b) the holder's adjusted tax basis in
     the shares of IMS stock (or warrants) surrendered in exchange therefor.

           A holder of Company Common Stock or Series B Preferred Stock who
     elects to exchange such stock for Series D Preferred Stock and does not
     enter into a Put/Call Agreement with respect to such stock should not
     recognize taxable gain or loss for federal income tax purposes with respect
     to such stock (except with respect to any cash received in lieu of
     fractional shares).

           The treatment of a holder of Company Common Stock or Series B
     Preferred Stock who elects to exchange such stock for Series D Preferred
     Stock and enters into a Put/Call Agreement with respect to such stock is
     uncertain, and is discussed in greater detail below under "CERTAIN FEDERAL
     INCOME TAX CONSEQUENCES OF THE MERGER - Receipt of Series D Preferred Stock
     Subject to Put and Call Rights."  Any such holder should consult his or her
     own tax advisor regarding the consequences of the transaction.

           Each holder of Company Common Stock, Series B Preferred Stock,
     Company Warrants or Company Options is urged to read the summary of
     principal federal income tax consequences of the Merger set forth below
     under "CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER," and to
     consult with his or her own tax advisor as to the specific tax consequences
     of the Merger to that holder.

(1) The unaudited consolidated pro forma per share data for the year ended
    December 31, 1994 and for the six months ended June 30, 1995 are based on
    Lilly's historical results from continuing operations adjusted to reflect
    the impact of the Merger as if it had occurred on January 1, 1994 and
    January 1, 1995, respectively. The consolidated pro forma per share data
    also assumes the number of shares of Lilly common stock outstanding and the
    weighted average number of shares of Lilly common stock outstanding used in
    the earnings per share calculations are reduced for the effect of the
    disposition of Guidant Corporation ("Guidant"). In addition, the unaudited
    pro forma consolidated earnings per share from continuing operations for the
    year ended December 31, 1994 assumes the acquisition of PCS was consummated
    on January 1, 1994.

    The unaudited consolidated pro forma book value per share at June 30, 1995
    reflects the impact of (i) the Merger; (ii) exclusion of the respective
    Guidant balances including elimination of the minority interest in Guidant;
    (iii) the effect of the tender of shares of Lilly common stock from the
    Guidant exchange offer on treasury stock; and (iv) recognition of the
    estimated net gain from the disposition of discontinued operations.

    The unaudited pro forma per share data is not necessarily indicative of
    Lilly's consolidated per share data had the Merger, Guidant transaction, or
    acquisition of PCS reflected therein actually been consummated at the
    assumed dates, nor is it necessarily indicative of Lilly's consolidated per
    share data for any future period. The unaudited pro forma consolidated per
    share data should be read in conjunction with Lilly's consolidated financial
    statements and notes thereto incorporated by reference in this Proxy
    Statement-Prospectus.

    Additional pro forma financial information, balance sheet and income
    statement are not presented since IMS does not fall within the definition of
    a "significant subsidiary" as defined in Rule 1-02 of Regulation S-X.

                              THE SPECIAL MEETING

TIME, DATE AND PLACE

              The Special Meeting will be held on ________, 1995, at _____ A.M.
local time, at ________________________.

PURPOSE OF THE MEETING

          At the Special Meeting, the IMS shareholders will be asked to consider
and vote upon the proposed merger of Subsidiary into IMS.  The Merger will
result in IMS becoming a subsidiary of Lilly, with all of IMS's outstanding
voting stock being owned by Lilly and all of IMS's other shareholders owning
non-voting Series D Preferred Stock and Series B Preferred Stock.

RECORD DATE AND OUTSTANDING SHARES

          Record Holders of shares of Company Common Stock, Series B Preferred
Stock and Series C Preferred Stock at the close of business on the Record Date
will be entitled to notice of and to vote at the Special Meeting.  Each issued
and outstanding share of Company Common Stock, Series B Preferred Stock and
Series C Preferred Stock is entitled to one vote per share with respect to the
Merger.  On the Record Date, there were 6,584,002 shares of Company Common Stock
issued and outstanding held by approximately 197 holders, 2,000,000 shares of
Series B Preferred Stock issued and outstanding held by approximately 23 holders
and 3,000,000 shares of Series C Preferred Stock issued and outstanding all of
which were held by wholly-owned subsidiaries of Lilly.

REQUIRED VOTE

          Under Colorado law and the Articles of Incorporation of IMS, the
affirmative vote of two-thirds of the outstanding shares of Company Common
Stock, Series B Preferred Stock and Series C Preferred Stock, voting together as
a single class, and the affirmative vote of two-thirds of the outstanding shares
of each of the Series B Preferred Stock and the Series C Preferred Stock, each
voting separately as a class, are required to approve the Merger.  In addition,
pursuant to the Merger Agreement, it is a condition to the consummation of the
Merger that the Merger be approved by the affirmative vote of shares
representing at least a majority of the voting power of the outstanding shares
of Company Common Stock and Series B Preferred Stock that are not owned by Lilly
or its subsidiaries.

          As of the Record Date, the directors of IMS and their affiliates
(other than Lilly or any subsidiary of Lilly) owned an aggregate of 3,337,795
shares of Company Common Stock, representing approximately 51% of the Company
Common Stock entitled to vote on the Merger, and 1,581,562 shares of Series B
Preferred Stock, representing 79% of the Series B Preferred Stock entitled to
vote on the Merger.  All of these shareholders have agreed with Lilly to vote
their shares in favor of the Merger.  In addition, Lilly, through its wholly-
owned subsidiaries, owns 160,200 shares of Company Common Stock and all of the
Series C Preferred Stock and will vote those shares in favor of the Merger.  The
shares of Company Common Stock, Series B Preferred Stock and Series C Preferred
Stock collectively owned by these shareholders and Lilly represent approximately
70% of the Company Common Stock, Series B Preferred Stock and Series C Preferred
Stock entitled to vote as a class on the Merger.  Thus, upon the vote of these
shareholders in accordance with such agreements, shareholder approval of the
Merger is assured.

          The Board of Directors of IMS (with one director absent) has
unanimously approved the proposed Merger and recommends approval and adoption of
the Merger Agreement by IMS shareholders (except that Dr. Hunt and Mr. Moley, as
Lilly's representatives on the Board, abstained from the Board's deliberations
and vote).  Each of the Boards of Directors of Lilly and Subsidiary, and Lilly,
as the sole

                                       10

 
shareholder of Subsidiary, have approved the proposed Merger.  Lilly shareholder
approval is not required for the consummation of the Merger.

REVOCABILITY OF PROXIES

          Shares of Company Common Stock, Series B Preferred Stock and Series C
Preferred Stock represented by a properly executed proxy received by IMS will,
unless such proxy is properly revoked prior to the Special Meeting, be voted at
the Special Meeting in accordance with the instructions thereon.  Shares
represented by properly executed proxies that do not contain instructions to the
contrary will be voted FOR approval of the proposed Merger and in the discretion
of the proxy holder as to any other matter that may properly come before the
Special Meeting or any adjournment or postponement thereof.  Abstention from
voting on the Merger will have the practical effect of voting against the Merger
since it is one less vote for approval.  The Board of Directors of IMS knows of
no other business that will be presented for consideration at the Special
Meeting other than the proposal to approve the Merger Agreement and the related
matters described in this Proxy Statement-Prospectus.  Proxies are being
solicited hereby on behalf of the Board of Directors of IMS.

          Any shareholder may revoke his or her proxy at any time before it is
voted by executing and delivering to IMS a proxy bearing a later date, by
delivering a written notice to the Secretary of IMS stating that the proxy is
revoked, or by voting in person at the Special Meeting.

SOLICITATION OF PROXIES

          The cost of the solicitation of proxies, including expenses incurred
by brokerage houses, nominees and fiduciaries in forwarding proxy materials to
beneficial owners, will be paid by IMS. In addition to solicitation by mail,
officers, directors and regular employees of IMS may solicit proxies by
telephone, telegram or by personal interview. Such persons will receive no
additional compensation for such services.

                        SPECIAL FACTORS TO BE CONSIDERED

     RISK FACTORS APPLICABLE TO IMS

               In addition to the other information contained elsewhere herein,
     shareholders of IMS, and particularly those who, if the Merger is approved,
     choose to receive Series D Preferred Stock, or options or warrants to
     acquire Series D Preferred Stock, or to hold their shares of Series B
     Preferred Stock, should carefully consider the risks of holding IMS equity
     securities, including the following:

               Possible Inability to Pay Dividends or Redeem Preferred Stock.
     The financial condition of IMS resulting from the factors described below
     may preclude it under state corporate law from paying dividends on Series B
     Preferred Stock or Series D Preferred Stock or from redeeming Series D
     Preferred Stock in accordance with the terms of such securities.  Lilly is
     not obligated to provide additional financing to IMS to permit IMS to pay
     dividends on preferred stock or to redeem Series D Preferred Stock in the
     future.  Accordingly there can be no assurance that IMS will pay future
     dividends as they accrue or redeem outstanding Series D Preferred Stock in
     a timely manner, if ever.  However, holders of Series D Preferred Stock who
     elect to enter into Put/Call Agreements will have the right to require
     Lilly to purchase such shares as provided in those agreements.  See
     "PUT/CALL AGREEMENTS."

               Controlling Shareholder.  Upon completion of the Merger, Lilly
     and/or its affiliates will own 100% of the Company's outstanding voting
     stock and will be the controlling shareholder of the Company.  Accordingly,
     Lilly will be able to control virtually every aspect of the Company's
     affairs.

               Historical Operating Losses and Negative Cash Flow From
     Operations.  As a result of its rapid growth, the investment required to
     establish its operating networks and the time required for networks to
     generate positive cash flow, the Company has incurred significant operating
     and net losses and negative cash flow since its inception.  At June 30,
     1995, IMS had an accumulated deficit of approximately $29.9 million.   The
     Company had net losses of approximately $3.7 million, $5.9 million and $4.3
     million for the fiscal years ended December 31, 1992, 1993 and 1994,
     respectively, and $6.5 million for the six month period ended June 30,
     1995.  The Company expects to continue to generate negative cash flow from
     operating activities while it emphasizes development and expansion of its
     IMS MEDACOM/(R)/ networks and until its operating networks have established
     a sponsor base generating sufficient recurring revenue to cover direct
     network operating expenses and the costs of corporate support and overhead.
     There can be no assurance that the Company will achieve or sustain
     profitability in the future.

               Long Sales Cycle; Dependence on Licensing Revenue.  The Company's
     long term recurring cash flow is dependent upon the Company being able to
     establish a substantial number of sponsors for its various networks and
     increasing the number of physicians with which the networks have
     connectivity.  The Company normally anticipates that it will take from 12
     to 36 months before a new network will generate a positive cash flow.
     During this period, the Company will expend substantial time, efforts and
     funds to obtain sponsors for a network, to market to physician subscribers
     and to increase network usage.  If the Company is unable to establish
     networks with a sufficient number of sponsors to provide positive cash
     flow, the Company will continue to incur losses in the future.  Moreover,
     pending the establishment of additional recurring revenue from fees paid by
     sponsors of networks, the Company will rely on fees from the periodic sales
     of network licenses and fees from existing sponsors.  There are no
     assurances that the Company will be able to generate sufficient cash flow
     therefrom to meet the Company's cash requirements.

               Competition.  The market for healthcare information systems is
     intensely competitive.  Computerized medical office management and data
     communication systems are offered to physicians, hospitals, payors and
     other potential network sponsors by a wide range of vendors, including
     manufacturers of computer equipment, software vendors, hospital information
     systems companies and systems integrators.  In addition, certain claims
     processing organizations, hospitals, third party administrators, insurers
     and/or other organizations provide direct computer communication links
     between the physician and the

                                       12

 
     organization.  These business firms have financial and other resources more
     extensive than those of the Company.

               The Company relies on copyrights, trademarks and service marks,
     nondisclosure and noncompetition agreements and technical measures to
     protect its proprietary rights pertaining to its software products and
     network technology.  Such protection may not preclude competitors from
     developing networks and software with features similar to those developed
     by the Company.  The Company's business and anticipated future success
     depend on its technology, expertise and experience, all of which could be
     duplicated by competitors.  There can be no assurance that future
     competition will not have a material adverse effect on the Company's
     business, financial condition and results of operations.

               In addition, the network services industry in general is impacted
     by evolving standards and technology.  The Company's ability to anticipate
     or guide these standards in the health care sector and to continue to apply
     advances in computer and telecommunications technology in the operation of
     its networks will be significant factors in the Company's success.  Many of
     the Company's competitors have significantly greater financial, technical,
     product development and marketing resources than the Company, and there is
     no assurance that the Company will remain competitive.

               Consolidation of the Healthcare Industry.  The rapid emergence of
     managed care plans and especially the movement toward risk sharing or
     capitated provider payment methodologies is resulting in dramatic changes
     in the healthcare industry.  The Company's market is being complicated by
     the formation of new multi-provider integrated delivery systems in which
     the goals of payors, provider institutions and hospitals become aligned.
     Many healthcare providers are consolidating to create larger healthcare
     delivery enterprises with greater regional market power.  As a result, the
     number of potential sponsors for the Company's networks could be reduced,
     thereby shrinking the Company's total market.

               Dependence on Key Management and Personnel.  The Company depends
     to a significant extent on certain executive officers and technical
     personnel.  The Company's growth and future success will depend in large
     part on its ability to attract, motivate and retain highly qualified
     personnel, in particular, trained and experienced professionals capable of
     developing, selling and installing healthcare information networks.
     Competition for such personnel is intense and there can be no assurance
     that the Company will be successful in hiring, motivating, training or
     retraining such qualified personnel.  The loss of key personnel or the
     inability to hire or retain qualified personnel could have a material
     adverse effect on the Company's business, financial condition and results
     of operations.  The Company does not currently maintain any key man life
     insurance policies on any of its management personnel or employees and does
     not have employment agreements with most of them.

               Limited Experience in Expanding Networks.  Because most of the
     Company's networks have become operational in the last two years, usage of
     many of these networks to date has been limited.  The Company will depend
     upon the growth of recurring revenue from these networks as they mature,
     without which the Company's future results may be adversely affected.  The
     Company's marketing strategy relies heavily on its ability to recruit local
     and national sponsors willing to pay fees to the Company to communicate
     with physicians and others using the networks.  There is no assurance that
     this marketing approach will be successful.  The Company's marketing
     efforts have been focused upon convincing hospitals, clinical laboratories,
     pharmacies, imaging centers and other medical payers and providers to
     convert from a traditional proprietary communications system approach of
     paper and phone based communications with physicians to the Company's
     nonproprietary and open architecture automated network solution.  There can
     be no assurance that these conversions will occur or that the Company's
     network services will be the method of communication employed by such
     users.

                                       13

 
     BACKGROUND TO THE MERGER

               Lilly, through its subsidiary, PCS, has been a shareholder of IMS
     since November 1994, when Lilly acquired the PCS pharmacy benefits
     management services business of McKesson.  At that time McKesson owned
     160,200 shares of Company Common Stock, 2,625,000 shares of Series C
     Preferred Stock and Warrants to buy an aggregate of 875,000 shares of
     Series C Preferred Stock at prices of $5 to $7 per share.  (See "- Prior
     Agreements/Relationship of the Parties - Stock Purchases by McKesson"
     below.)  Each share of Series C Preferred Stock is convertible into one
     share of Company Common Stock.  At the time McKesson also held various
     agreements with IMS that are described below under "- Prior
     Agreements/Relationship of the Parties - McKesson Sponsorship Agreement"
     and "- Prior Agreements/Relationship of the Parties - McKesson
     Stockholder's Rights Agreement."  By acquiring PCS, Lilly acquired
     McKesson's IMS shares and Warrants and contract rights.  In January 1995,
     PCS exercised a Warrant to purchase 375,000 shares of Series C Preferred
     Stock at a price of $5 per share.  As a result of the foregoing, since
     November 1994, Lilly, through PCS, has owned, or had the right to acquire,
     about 28% of the Company Common Stock on a fully-diluted basis and has been
     entitled to have two representatives on the IMS Board of Directors.  Mr.
     Kevin Moley, an employee of PCS, has served as a Lilly representative on
     the IMS Board since November 1994.  Mr. Moley served as a McKesson
     representative on the IMS Board since January 1994 and also served as
     interim Chief Executive Officer of IMS for the period from July 1994 to
     December 1994.  Dr. Michael Hunt has served as a Lilly representative on
     the IMS Board since December 1994.

               In December 1994, Lilly indicated to IMS that it was considering
     the possibility of proposing a transaction in which Lilly would acquire
     some or all of the shares of Company Common Stock that it did not already
     own.  At a meeting held on December 20, 1994, the IMS Board established a
     special committee (the "Special Committee") to consider and explore any
     proposal received from Lilly for such a transaction, as well as to consider
     and explore alternative transactions.  The Special Committee consisted of
     Messrs. Charles I. Brown, Alan S. Danson, John W. Hanes, Jr., David R.
     Holbrooke, James A. Larson and John A. McChesney, none of whom is an
     officer, employee or affiliate of Lilly and only one of whom, Mr. Brown, is
     an executive officer of IMS.  The Special Committee was authorized to
     retain a financial advisor and legal counsel.  At the request of the
     Special Committee, IMS retained special legal counsel to work with IMS's
     regular outside counsel and the investment banking firm of Smith Barney to
     serve as financial advisor in connection with any proposal from Lilly or
     other similar alternative transaction.

               On January 16, 1995, representatives of Smith Barney and IMS's
     legal counsel met with representatives of Lehman Brothers ("Lehman"),
     Lilly's financial advisors.  At that meeting, Lehman indicated that Lilly
     was aware of IMS's need for working capital.  Lehman stated that Lilly
     would be prepared to make a proposal to acquire the remainder of the shares
     of IMS it did not own in a cash transaction valued in the $5.50 to $6.50
     per share range if IMS were interested in receiving such a proposal.  Over
     the course of the next several weeks, the Special Committee met several
     times by telephone with its legal and financial advisors to review that
     possible proposal and to discuss the alternatives that were available to
     IMS in light of the contract rights that may be held by Lilly as a result
     of its acquisition of PCS.  The alternatives considered by the Special
     Committee included a merger or other strategic transaction with Lilly or
     with other possible parties, an initial public offering, a private
     placement of securities with new or existing investors and the
     establishment of additional sponsor arrangements.  The Special Committee,
     with the advice of Smith Barney, determined that this value range was
     inadequate and that a proposal in that range would not warrant further
     exploration.  In mid-February, following these meetings, Smith Barney
     advised Lehman that IMS did not want to pursue a transaction in that value
     range although it might be willing to consider a proposal for a transaction
     at a higher value.  Lehman also was advised that IMS would begin to explore
     alternative transactions to raise needed working capital, such as an
     initial public offering of shares of Company Common Stock.

               In the course of further discussions to see if Lilly would
     consider proposing a higher value, IMS provided Lilly with certain
     information about IMS that was not available publicly and that had not

                                       14

 
     previously been made available to IMS shareholders.  This information
     included business plans prepared by IMS's senior management which included
     forecasts and projections of the future financial performance of IMS.  The
     financial forecasts furnished to Lilly by IMS included annual revenue
     estimates for 1995 through 1999 of approximately $32 million, $53 million,
     $82 million, $115 million and $140 million, respectively, and operating
     profits (before minority interest and provision for income taxes) for the
     same years at approximately $1 million, $10 million, $22 million, $37
     million and $48 million, respectively.  Numbers of physicians connected to
     IMS networks for the same years were forecast to be approximately 33,000,
     53,000, 76,000, 98,000 and 114,000, respectively.  All of the estimates
     assumed that at least $27.7 million in additional working capital during
     the five years would be required.  These estimates were prepared by senior
     management concerning the anticipated future performance of IMS as a stand-
     alone entity, without giving effect to any offer from Lilly, including the
     Merger.

               IMS does not as a matter of course make public, or disclose
     generally to its shareholders, any projections as to future performance or
     earnings, and the projections set forth above are included in this Proxy
     Statement-Prospectus only because the information was made available to
     Lilly by IMS.  IMS has informed Lilly that the projections were not
     prepared with a view to public disclosure or compliance with the published
     guidelines of the Commission or the guidelines established by the American
     Institute of Certified Public Accountants regarding projections or
     forecasts.  IMS also has informed Lilly that its financial forecasts are,
     in general, prepared solely for internal use and capital budgeting and
     other management decision-making purposes and are subjective in many
     respects and thus susceptible to various interpretations and periodic
     revision based on actual experience and business developments.  Projected
     information of this type is based on estimates and assumptions that are
     inherently subject to significant economic and competitive uncertainties
     and contingencies, all of which are difficult to predict and many of which
     are beyond the control of IMS or Lilly and their respective financial
     advisors.  Many of the assumptions upon which the projections were based
     are dependent upon economic forecasting (both general and specific to IMS's
     business), which is inherently uncertain and subjective.  Accordingly,
     actual results may vary materially from such projections, and none of IMS
     or Lilly or their respective financial advisors assumes any responsibility
     for the accuracy or validity of any of the projections.  The inclusion of
     the foregoing projections should not be regarded as an indication that IMS
     or Lilly considers such projections an accurate prediction of future
     events, and Lilly has not relied on them as such.

               During March and April of 1995, IMS undertook to explore several
     alternative transactions aimed at raising working capital.  During this
     period the Special Committee met frequently by telephone with IMS's legal
     counsel and Smith Barney.  Two additional current directors who are members
     of IMS's senior management, Messrs. Kevin R. Green and James T. Murphy, who
     were not then directors, participated in many of these meetings by
     invitation of the Special Committee.  Substantial progress was made
     preparing IMS for an initial public offering that might be effected with
     Smith Barney serving as lead underwriter.  IMS also had discussions with
     third parties about possible minority investments by such third parties in
     IMS.  At a meeting of the IMS Board on April 21, 1995, the Board heard a
     presentation from Smith Barney concerning the viability of an initial
     public offering of IMS stock at that time.  Dr. Hunt, one of the members of
     the IMS Board employed by Lilly, stated that Lilly would prefer to have IMS
     suspend efforts toward an initial public offering or placement of shares
     with minority investors and instead explore a transaction in which Lilly
     would acquire IMS.  The Board determined that the working capital needs of
     IMS would not permit IMS to suspend these financing efforts and authorized
     management to proceed with preparations for an initial public offering to
     be consummated as soon as possible and to continue discussions with Lilly
     or potential minority investors to bridge IMS's working capital needs until
     the public offering could be completed.  Shortly after this meeting, Lilly
     advised IMS that it believed the contract rights obtained from McKesson
     provided Lilly a right of prior approval of any sale of stock to one such
     potential investor, although not over certain other sales or an initial
     public offering.

               On May 1, 1995, Lilly sent a letter to IMS outlining the terms of
     a proposed transaction Lilly was prepared to discuss with IMS.  Under this
     proposal, Lilly would obtain control of IMS through a series of purchases
     of Company Common Stock.  The proposed transaction contemplated purchases
     by

                                       15

 
     Lilly from the IMS shareholders at a price of $7.00 per share of Company
     Common Stock (subject to adjustment) and purchases by Lilly from IMS of
     newly issued shares ranging in price from $5.25 to $6.00 per share of
     Company Common Stock (subject to adjustment).  Lilly would also commit to
     make an offer to any remaining holders of Company Common Stock three years
     after acquisition of control at a price of $8.29 per share of Company
     Common Stock (calculated based on a $7.00 per share price, plus interest on
     such amount in the amount of 6% per annum).

               The Special Committee met with IMS's legal counsel and Smith
     Barney to discuss this proposed transaction on May 2, 1995.  Smith Barney
     advised the Special Committee that, while the proposed transaction would
     provide needed working capital to IMS and liquidity to IMS shareholders,
     the offer appeared to be low and did not include any premium for either
     control or strategic value.  Smith Barney believed that IMS could sell
     shares in the contemplated initial public offering in the same $7.00 per
     share range.  The Special Committee and its advisors discussed the fact
     that a transaction with Lilly would eliminate the uncertainty caused by the
     differing interpretations of Lilly's contract rights and also would
     eliminate the risk that a financing could not be completed if the business
     did not achieve projected results in the near term.

               Following this meeting, representatives of IMS and its legal
     counsel and Smith Barney had further conversations with representatives of
     Lilly about the proposed transaction.  Lilly was advised that the proposed
     transaction did not provide enough value for the IMS shareholders and that
     a structure that would result in a tax-free transaction for IMS
     shareholders was preferred.  On May 9, 1995, members of the Special
     Committee, Messrs. Green and Murphy, IMS's legal counsel and Smith Barney
     met with representatives of Lilly, Lehman and Lilly's counsel to continue
     negotiations concerning a possible transaction.  Lilly indicated that if
     the parties could agree on the parameters of a proposed transaction, Lilly
     would offer to provide interim financing to IMS and thus would ask that IMS
     suspend efforts toward an initial public offering or other financing.  At
     this meeting the parties agreed to negotiate a non-binding term sheet
     providing for a transaction that would provide $8.00 per share of Company
     Common Stock with an opportunity for tax deferral to IMS shareholders and
     would provide Lilly with control of IMS.  Lilly indicated that, as part of
     any such transaction, it would require that the members of the Board, in
     their individual capacity as shareholders, enter into appropriate support
     arrangements aimed at ensuring that the transaction would be consummated.
     Over the next several weeks the parties negotiated successive drafts of the
     non-binding term sheet.

               On June 12, 1995, Lilly and IMS executed a "Non-Binding Term
     Sheet" (the "Term Sheet") pursuant to which they agreed to discuss a
     definitive agreement under which Lilly or an affiliated entity would
     acquire IMS on terms outlined in the Term Sheet.  Those terms with some
     modifications are reflected in the Merger Agreement.

               The Term Sheet did not create any legal obligations, except that
     (1) IMS agreed that until such time as IMS reasonably determined and
     notified Lilly that the parties could not reach a definitive agreement, IMS
     would conduct its business in the ordinary course and any extraordinary
     transaction material to its business would be discussed with and approved
     by Lilly; (2) IMS agreed that it would immediately suspend all efforts to
     finance its business through a public offering or private placement of its
     shares or otherwise, or to sell IMS or any of its business or assets, until
     such time as IMS reasonably determined and notified Lilly that the parties
     could not reach a definitive agreement; and (3) IMS and Lilly agreed that
     they would keep the proposed transaction strictly confidential.  In
     addition, Lilly agreed to loan IMS $3 million upon execution of the Term
     Sheet, and IMS agreed to amend the Warrant held by PCS to defer the
     increase in exercise price of $6 to $7 per share scheduled for July 12,
     1995 until 30 days after the earlier of the termination of the definitive
     agreement and such time as IMS or Lilly reasonably determined and notified
     the other party that the parties could not reach a definitive agreement.

               Upon execution of the Term Sheet, Lilly loaned IMS $3 millon to
     be repaid on July 1, 1996 with interest at the annual rate of 10%.  The
     loan is subordinated to the indebtedness outstanding on

                                       16

 
     June 12, 1995 and is secured by a pledge of most of the assets of IMS,
     including shares of subsidiaries.  The loan becomes immediately due and
     payable if IMS breaches the Merger Agreement, subject to certain rights of
     IMS to cure such breach.  On July 27, 1995, Lilly loaned IMS an additional
     $1 million on the same terms as applied to the June 12 loan.

               Following the execution of the Term Sheet, Lilly engaged in a due
     diligence review of the business and operations of IMS.  While this review
     was ongoing, the parties negotiated the terms of the Merger Agreement.
     During the course of the extensive negotiations and discussions concerning
     the Merger Agreement, the Special Committee met frequently by telephone
     with IMS's legal counsel and Smith Barney and also received periodic
     updates from Mr. Brown, who participated actively in such negotiations and
     discussions as a member of the Special Committee and of senior management
     of IMS.

               On August 2, 1995, a meeting of the IMS Board was held at which
     five members of the Special Committee and Messrs. Green and Murphy were in
     attendance.  One member of the Special Committee was unable to attend and
     Dr. Hunt and Mr. Moley, as Lilly's representatives on the Board, did not
     attend except for a brief period during which they were in attendance at
     the invitation and request of the other members in attendance.  Smith
     Barney and legal counsel reviewed with the Board the terms of the Merger
     and the Merger Agreement.  Smith Barney orally advised the Board that, in
     its opinion, as of the date of such opinion, the consideration to be
     received by IMS shareholders (other than Lilly and its subsidiaries) in the
     Merger was fair to such shareholders from a financial point of view.  The
     Board discussed at length the conditions to the parties' obligations to
     consummate the Merger and the risk that one or more of those conditions
     would not be satisfied.  In that connection, the Board invited Dr. Hunt and
     Mr. Moley to join the meeting to discuss with the Board Lilly's
     expectations and intentions with respect to IMS's employees and its
     business plans.  Dr. Hunt and Mr. Moley assured the Board that Lilly
     intended to continue to operate the business as an open architecture
     utility model.  Lilly also stated that it did not anticipate any
     significant personnel changes at that time.

               At Lilly's request, each of the IMS directors, other than Dr.
     Hunt and Mr. Moley, agreed to enter into support agreements concurrently
     with the execution of the Merger Agreement.  Pursuant to the support
     agreements, each such person, in his capacity as an IMS shareholder, agreed
     that until the Merger is consummated or the Merger Agreement is terminated
     he will not transfer his IMS shares (subject to certain exceptions), will
     vote his IMS shares in favor of the Merger and will refrain from soliciting
     or supporting other proposals for the merger or sale of IMS.  Each such
     person also agreed to exchange any shares of Series B Preferred Stock that
     he owns for cash and/or Series D Preferred Stock as he may elect pursuant
     to Merger Agreement, and to waive any rights that he may have to register
     IMS securities under the Securities Act or to require IMS to provide
     information to facilitate public resales of such securities.

               Based on its review and consideration of the proposed Merger and
     the Merger Agreement, the Board determined that the proposed Merger was
     fair and reasonable and in the best interests of the Company and its
     shareholders (other than Lilly and its subsidiaries) and approved the
     Merger and the Merger Agreement.  The Merger Agreement was executed on
     August 2, 1995.

     LILLY'S PURPOSE OF THE MERGER

               For Lilly, the Merger will provide an opportunity to forge closer
     ties with health care providers and payers, allowing it to deliver
     information quickly to people who provide care and make health care
     decisions.  For Lilly, the primary purpose for the Merger is to expand
     Lilly's pharmaceutical management services by connecting to the existing
     25,000 physicians connected to IMS Networks.  Lilly intends to utilize the
     connectivity to provide disease management utilization tools to the
     existing base and future IMS subscribers.  Lilly's desire is to expand its
     technological intervention capabilities and connectivity to not only
     physicians but to all disparate sources of the health care community.  IMS
     is expected to play an integral role in the creation and expansion of this
     health care network.

     RECOMMENDATION OF THE IMS BOARD OF DIRECTORS; FAIRNESS OF THE MERGER

               The Board of Directors of IMS (with one director absent) has
     approved the Merger, determined that the proposed Merger is fair and
     reasonable and in the best interests of the Company and its shareholders
     (other than Lilly and its subsidiaries) and recommended that such
     shareholders approve and adopt the Merger Agreement (except that Dr. Hunt
     and Mr. Moley, as Lilly's representatives on the Board, abstained from the
     Board's deliberations and vote).  The Board based its recommendation on a
     number of factors, including the following:

               (a)  Information with respect to the financial condition, results
     of operations, business and prospects of the Company, and, in particular,
     the failure of the Company to meet its budgeted results for the year to
     date and the need for substantial amounts of working capital in the near
     term.

               (b)  The oral opinion of Smith Barney, delivered to the Board on
     August 2, 1995 and subsequently confirmed in writing, that the
     consideration to be received by IMS's shareholders (other than Lilly)
     pursuant to the Merger was fair to such shareholders from a financial point
     of view as of the date of such opinion and its subsidiaries.

               (c)  Possible alternatives to the Merger (including continuing to
     operate as an independent entity, engaging in another strategic transaction
     or selling stock publicly or privately), the range of possible values to
     the Company's shareholders of such alternatives, and the timing and
     likelihood of actually accomplishing those alternatives.

               (d)  The fact that Lilly has reported that it has available
     liquid assets sufficient to promptly consummate the Merger.

               (e)  The terms and conditions of the Merger Agreement, including
     the amount and form of the consideration to be received thereunder, and the
     fact that the terms of the Merger Agreement and the consideration paid to
     shareholders were determined through arm's-length negotiations with the
     Special Committee and that members of the Special Committee voted
     unanimously (with one member absent) for approval of the Merger and the
     Merger Agreement.

               (f)  The uncertainty that exists as to the rights Lilly has under
     the McKesson contracts obtained as part of its acquisition of PCS and the
     likelihood that such uncertainty would limit the alternatives to the Merger
     available to IMS and affect the cost and timing of pursuing any such
     alternative.

               (g)  The impact of the Merger on the Company's employees and its
     business plans.

               (h)  The willingness of each member of the Board, in his
     individual capacity as shareholder, to support the Merger and to enter into
     the support agreements required by Lilly in connection with the proposed
     Merger Agreement.

               In view of the wide variety of factors considered in connection
     with its evaluation of the Merger, the IMS Board found it impracticable to,
     and did not, quantify or otherwise assign relative weights to the specific
     factors considered in reaching their decisions.

     OPINION OF FINANCIAL ADVISOR

               IMS retained Smith Barney as its financial advisor in connection
     with the Merger.  In connection with such engagement, IMS requested that
     Smith Barney evaluate the fairness, from a financial point of view, to the
     IMS shareholders (other than Lilly and its affiliates) of the Cash Election
     and the Stock Election (collectively, the "Elections") to be offered to
     such shareholders in the Merger. Smith Barney rendered an oral opinion to
     the IMS Board on August 2, 1995, which was subsequently confirmed in
     writing, in each case to the effect that, as of the date of such

                                       18

 
     opinion, the Elections to be offered to the IMS shareholders (other than
     Lilly and its subsidiaries) in the Merger was fair, from a financial point
     of view, to such shareholders.

               The full text of the written opinion of Smith Barney, dated
     August 2, 1995, which sets forth the assumptions made, procedures followed,
     matters considered, limitations on and the scope of the review by Smith
     Barney in rendering its opinion, is attached as Appendix C to this Proxy
     Statement-Prospectus. SHAREHOLDERS ARE URGED TO READ THE OPINION IN ITS
     ENTIRETY.

               In connection with rendering its oral opinion and preparing its
     written and oral presentations to the IMS Board, Smith Barney performed a
     variety of financial analyses, including those summarized below.  The
     summary set forth below does not purport to be a complete description of
     the analyses performed by Smith Barney in this regard.  Smith Barney's
     opinion is directed only to the fairness, from a financial point of view,
     to the IMS shareholders of the consideration to be received by such
     shareholders in the Merger, does not address the relative merits of the
     Merger as compared to any alternative business strategies that might exist
     for IMS or the effect of any other transaction in which IMS may engage nor
     does it address any other aspect of the Merger. Smith Barney's opinion does
     not constitute a recommendation to any IMS shareholder as to how such
     shareholder should vote with respect to the Merger. In addition, Smith
     Barney was not asked to, and did not, express any opinion as to the
     relative merits of receiving the cash consideration or the stock
     consideration in the Merger and, accordingly, Smith Barney's opinion does
     not constitute a recommendation to any IMS shareholder as to whether to
     make a Cash Election and receive the cash consideration or not to make a
     Cash Election and receive the stock consideration. Smith Barney was not
     asked to, and did not, express any opinion as to (a) what the value of the
     Series D Preferred Stock actually will be when issued to IMS shareholders
     pursuant to the Merger or the price at which the Series D Preferred Stock
     will trade, if at all, subsequent to the Merger, (b) any Election to
     Retain Series B Preferred Stock or (c) the relative fairness of the Merger 
     to the holders of the Company Common Stock and the holders of the Series B 
     Preferred Stock. The summary of Smith Barney's opinion set forth below is
     qualified in its entirety by reference to the full text of such opinion
     attached as Appendix C.

               In arriving at its opinion, Smith Barney reviewed the Merger
     Agreement and held discussions with certain senior officers, directors and
     other representatives and advisors of IMS concerning the business,
     operations and prospects of IMS.  Smith Barney examined certain business
     and financial information relating to IMS as well as certain financial
     forecasts and other data for IMS which were provided to Smith Barney by the
     management of IMS.  Smith Barney reviewed the financial terms of the Merger
     as set forth in the Merger Agreement in relation to, among other things:
     IMS's historical and projected earnings and the capitalization and
     financial condition of IMS.  Smith Barney considered, to the extent
     publicly available, the financial terms of certain other transactions that
     Smith Barney considered comparable to the Merger and analyzed certain
     financial and other publicly available information relating to the
     businesses of other companies whose operations Smith Barney considered
     comparable to those of IMS.  Smith Barney also conducted such other
     analyses and examinations and considered such other financial, economic and
     market criteria as Smith Barney deemed necessary to arrive at its opinion.

               In rendering its opinion, Smith Barney assumed and relied,
     without independent verification, upon the accuracy and completeness of all
     financial and other information publicly available or furnished to or
     otherwise reviewed by or discussed with Smith Barney.  Except as described
     herein, Smith Barney did not conduct any review or investigation of IMS or
     Lilly.  With respect to financial forecasts and other information provided
     to or otherwise reviewed by or discussed with Smith Barney, Smith Barney
     assumed that such forecasts and other information were reasonably prepared
     on bases that reflected the best currently available estimates and
     judgments of IMS's management as to the expected future financial
     performance of IMS.  In addition, Smith Barney did not make, nor was it
     provided with, an independent evaluation or appraisal of the assets,
     liabilities (contingent or otherwise) or reserves of IMS nor did Smith
     Barney make any physical inspection of the properties or assets of IMS.  No
     limitations were imposed on Smith Barney with respect to the investigations
     made or procedures followed by Smith Barney in rendering its opinion.
     Smith Barney's opinion necessarily is based on financial, stock market and
     other conditions and circumstances existing and disclosed to Smith Barney
     as of the date of its opinion.

               In preparing its opinion to the Board of Directors of IMS, Smith
     Barney performed a variety of financial and comparative analyses, including
     those described below.  The summary of such analyses does not purport to be
     a complete description of the analyses underlying Smith Barney's opinion or
     of its presentations to the IMS Board.  The preparation of a fairness
     opinion is a complex analytical

                                       19

 
     process involving various determinations as to the most appropriate and
     relevant methods of financial analyses and application of those methods to
     the particular circumstances and, therefore, such opinion is not readily
     susceptible to summary description.  In arriving at its opinion, Smith
     Barney did not attribute any particular weight to any analysis or factor
     considered by it, but rather made qualitative judgments as to the
     significance of each analysis and factor.  Accordingly, Smith Barney
     believes that its analyses must be considered as a whole and that selecting
     portions of its analyses or the factors considered by it, without
     considering all analyses and factors, could create a misleading or
     incomplete view of the processes underlying such analyses and its opinion.
     In its analyses, Smith Barney made numerous assumptions with respect to
     IMS, industry performance, general business, economic, market and financial
     conditions and other matters, many of which are beyond the control of IMS.
     The estimates contained in such analyses are not necessarily indicative of
     actual values or predictive of future results or values, which may be
     significantly more or less favorable than those suggested by such analyses.
     In addition, analyses relating to the value of businesses or securities do
     not purport to be appraisals or to reflect the prices at which businesses
     or securities may actually be sold.  Accordingly, such analyses and
     estimates are inherently subject to substantial uncertainty.

               Comparable Company Analysis.  Using publicly available
     information, Smith Barney analyzed, among other things, the closing stock
     prices and market values of the following health care information
     technology companies:  Cerner Corp.; CliniCom, Inc.; CyCare Systems, Inc.;
     GMIS Inc.; HBO & Company ("HBO"); HCIA, Inc.; Health Management Systems,
     Inc.; Medaphis Corp.; Medic Computer Systems, Inc.; Medicus Systems Corp.;
     Phamis, Inc.; and Shared Medical Systems Corp. (collectively, the
     "Comparable Companies").  Smith Barney compared the results of IMS to the
     results of the Comparable Companies.

               Smith Barney compared market values as multiples of historical
     and estimated net income.  The high, low and mean multiples of net income
     of the Comparable Companies for the latest twelve months ("LTM") were 63.3,
     19.0 and 40.6.  The high, low and mean multiples of estimated 1996 net
     income of the Comparable Companies were 35.6, 15.8 and 26.1, respectively.
     Smith Barney also compared the total enterprise values (equity market value
     plus total debt and the book value of preferred stock, minus cash and cash
     equivalents) to historical earnings before interest and taxes ("EBIT") and
     to historical earnings before interest, taxes, depreciation and
     amortization ("EBITDA") and the total enterprise values plus capitalized
     leases to historical revenues and to historical earnings before interest,
     taxes, depreciation, amortization and rent ("EBITDAR").  The high, low and
     mean multiples of LTM EBIT of the Comparable Companies were 35.3, 11.1 and
     24.5, respectively; of EBITDA of the Comparable Companies, 28.4, 8.6 and
     17.9, respectively.  The high, low and mean multiples of LTM revenues of
     the Comparable Companies were 6.5, 1.5 and 3.9, respectively; of EBITDAR of
     the Comparable Companies, 24.7, 8.5 and 16.6, respectively.

               Using a range of representative multiples derived from these
     calculations of total enterprise value plus capitalized leases to LTM
     revenues, Smith Barney derived a range of implied equity value of IMS of
     approximately $67.7 million to $90.6 million, which reflected a range of
     implied value per share of Company Common Stock (or equivalent) of $4.68
     to $6.26.  Using a range of representative multiples derived from these
     calculations of market value to estimated 1996 net income, Smith Barney
     derived a range of implied equity value of IMS of approximately $69.0
     million to $93.4 million, which reflected a range of implied value per
     share of Company Common Stock (or equivalent) of $4.77 to $6.46.

               Selected Merger and Acquisition Transactions Analysis.  Using
     publicly available information, Smith Barney analyzed the purchase prices
     and transaction values in the following selected merger and acquisition
     transactions involving health care information services companies:
     HBO/CliniCom; HBO/First Data Health System Group; Medaphis Corp./Automation
     Atwork; Thomson Corp./MEDSTAT Group; HBO/Serving Software; and Inforum
     Inc./MEDSTAT Systems Inc. (collectively, the "Comparable Transactions").

                                       20

 
               Smith Barney compared the purchase prices as multiples of
     historical net income and book value.  The high, low and mean multiples of
     LTM net income were 66.2, 12.0 and 38.6, respectively; of book value, 7.5,
     2.5 and 4.5, respectively.  Smith Barney also compared transaction values
     as a multiple of historical revenues and EBIT.  The high, low and mean
     multiples of LTM revenues were 7.9, 1.4 and 4.8, respectively; of LTM EBIT,
     49.4, 6.4 and 30.7, respectively.

               Using a range of representative multiples derived from these
     calculations of transaction value to LTM revenues, Smith Barney derived a
     range of implied equity value of IMS of approximately $82.6 million to
     $110.7 million, which reflected a range of implied value per share of
     Company Common Stock (or equivalent) of $5.71 to $7.66.

               No company, transaction or business used in the comparable
     company and selected merger and acquisition transactions analyses is
     identical to IMS or the Merger.  Accordingly, an analysis of the results of
     the foregoing is not entirely mathematical; rather it involves complex
     considerations and judgments concerning differences in financial and
     operating characteristics and other factors that could affect the
     acquisition or public trading value of the comparable companies or the
     business segment or company to which they are being compared.

               Discounted Cash Flow Analysis.  Smith Barney performed a
     discounted cash flow analysis of the projected free cash flow of IMS for
     the fiscal years ended December 31, 1996 through December 31, 1998,
     assuming, among other things, discount rates of 30%, 35% and 40% and
     terminal multiples of 1998 EBITDA of 5.0, 6.0, 7.0 and 8.0.  Utilizing
     these assumptions, Smith Barney arrived at a range of implied equity value
     of IMS of approximately $90.6 million to $118.7 million, which reflected a
     range of implied value per share of Company Common Stock (or equivalent) of
     $6.26 to $8.21.

               Initial Public Offering Analysis.  Smith Barney also analyzed the
     continued viability and attractiveness of an initial public offering of
     shares of Company Common Stock.  However, Smith Barney concluded that an
     initial public offering was not viable and was therefore irrelevant in
     their analysis of the fairness of the consideration to be received by
     shareholders of IMS in the Merger.

               Smith Barney is a nationally recognized investment banking firm
     and as part of its investment banking business, Smith Barney is regularly
     engaged in the valuation of businesses and their securities in connection
     with mergers and acquisitions, negotiated underwritings, secondary
     distributions of listed and unlisted securities, private placements and
     valuations for estate, corporate and other purposes.  The Special Committee
     selected Smith Barney because of Smith Barney's experience in transactions
     similar to the Merger as well as Smith Barney's knowledge of the health
     care information services industry generally.

               As compensation for Smith Barney's services as financial advisor
     to IMS in connection with the Merger, IMS has agreed to pay Smith Barney:
     (i) a retainer fee of $100,000; (ii) an opinion fee of $500,000, which was
     payable upon delivery by Smith Barney of its opinion; and (iii) a
     transaction fee of approximately $______, payable upon consummation of the
     Merger, against which the retainer fee and the opinion fee will be
     credited.  IMS has also agreed to reimburse Smith Barney for certain
     expenses incurred in connection with its engagement and to indemnify Smith
     Barney and its affiliates against certain liabilities, including certain
     liabilities under the Federal securities laws relating to, arising out of
     or in connection with its engagement.  In the ordinary course of its
     business, Smith Barney may trade the securities of Lilly for its own
     account and for the accounts of its customers and, accordingly, may at any
     time hold a long or short position in such securities.

     PRIOR AGREEMENTS/RELATIONSHIPS OF THE PARTIES

               In June, 1993, McKesson made its initial investment in IMS by
     purchasing 50,000 shares of Company Common Stock at $5 per share, and in
     September 1993 by purchasing a note in the principal amount of $500,000
     convertible into Company Common Stock.  Pursuant to a Stock Purchase
     Agreement, dated January 6, 1994, McKesson purchased 1,250,000 shares of
     Series C Preferred Stock at a price of $4 per share in January 1994 payable
     in part by cancellation of the $500,000 convertible note, and purchased
     1,000,000 shares at a price of $5 per share in July 1994.  Also pursuant to
     that Agreement, McKesson acquired Warrants to purchase an aggregate of
     1,250,000 shares of Series C Preferred Stock at initial exercise prices of
     $5 to $6 per share.  McKesson purchased from an IMS shareholder an
     additional 110,200 shares of Company Common Stock at $5 per share in April,
     1994.  PCS exercised a Warrant in November 1994 for 375,000 shares of
     Series C Preferred Stock at $5 per share.  On November 21, 1994, Lilly
     acquired the PCS pharmacy benefits management services business of
     McKesson, together with McKesson's IMS shares, Warrants and contract
     rights.  In January 1995, PCS exercised a Warrant for 375,000 additional
     shares of Series C Preferred Stock, at a price of $5 per share.  PCS
     continues to hold a Warrant to purchase 500,000 shares of Series C
     Preferred Stock at a price of $6 or $7 per share, depending on the date of
     exercise, exercisable until July 1996.

          McKesson Sponsorship Agreement

               McKesson and IMS entered into a Network Sponsorship and
     Participation Agreement, dated November 17, 1993 (the "McKesson Sponsorship
     Agreement"), under which McKesson was granted various rights to utilize IMS
     Networks to send and receive information between IMS Network sites and
     McKesson's clients, and to link IMS Networks to McKesson's transaction
     processing and data base management infrastructure to send and receive
     information in support of a variety of services.  Under the Agreement,
     McKesson paid a sponsorship fee of $1 million which was subsequently
     credited against the purchase of shares of Series C Preferred Stock in July
     1994 described above.  All of McKesson's rights under this Agreement are
     now held by PCS as a result of Lilly's acquisition of PCS in November 1994.

               Term.  The McKesson Sponsorship Agreement will continue until
               ----                                                         
     December 1998 and will be renewed automatically for successive one-year
     terms unless McKesson cancels the Agreement or fails to make certain
     minimum payments to IMS.

               Network Services.  IMS is obligated to provide certain services
               ----------------                                               
     to McKesson, including:

              (a)  With respect to existing IMS Networks located in the top
          fifty U.S. markets, IMS will provide, or in some cases will use its
          best efforts to provide, access for McKesson Product Lines to all
          Subscribers designated by McKesson.

              (b)  IMS will provide access for the McKesson Product Lines to all
          Subscribers designated by McKesson in all new IMS Networks established
          in the top fifty U.S. markets, and McKesson will have the right to
          become the initial Sponsor for such new IMS Networks.

              (c)  IMS will provide access for the McKesson Product Lines to all
          current subscribers designated by McKesson in IMS Networks in
          secondary markets.  IMS and McKesson will negotiate in good faith the
          terms on which access would be made available to McKesson to new
          Subscribers in such Networks.

              (d)  IMS will provide and maintain for each IMS Network the
          ComCenter System, related personnel and services needed to support
          current and future IMS Networks.

              (e)  IMS will assist McKesson to develop and implement a plan to
          recruit prospective subscribers specified by McKesson for access to
          the McKesson Product Lines.

                                       22

 
              (f)  IMS will develop and execute a technical implementation plan
          for each IMS Network, including meetings with appropriate personnel of
          McKesson and McKesson's clients.

              (g)  IMS will be responsible for installation of licensed software
          and for providing training, support, IMS Network administration and
          updates and enhancements of licensed software to subscribers sponsored
          by McKesson.

              Fees.  In exchange for the services described above, McKesson is
              ----                                                            
     obligated to pay IMS certain message volume fees related to the volume of
     messages for each subscriber site sponsored by McKesson, plus annual
     minimum sponsor fees, plus certain installation and training fees.  To
     date, no fees have become payable under the McKesson Sponsorship Agreement
     and the first $1 million of fees under the Agreement was prepaid by
     McKesson and is unused as of the date hereof.

              Approval Rights.  IMS will not introduce Prescription Benefit
              ---------------                                              
     Management Services throughout the term of the McKesson Sponsorship
     Agreement without the approval and except on terms acceptable to McKesson.

              Database/Information Services.  McKesson may elect to use IMS
              -----------------------------                                
     Networks to provide physicians and other health care entities with access
     to McKesson proprietary data base/information services.  Subject to certain
     limitations, McKesson has the right to capture and compile data transmitted
     across IMS Networks in connection with McKesson Product Lines and to
     generate, use and sell compilations, analyses and reports based on such
     data.

              Obligations of McKesson.  McKesson will provide reasonable and
              -----------------------                                       
     appropriate cooperation with IMS's efforts to recruit potential
     Subscribers, and will provide IMS Network participants with access to the
     data center of PCS consistent with access customarily provided to PCS
     clients.

         McKesson Stockholder's Rights Agreement

              In connection with McKesson's initial purchase of Series C
     Preferred Stock, IMS and McKesson executed a Stockholder's Rights
     Agreement, dated January 6, 1994 (the "McKesson Stockholder's Rights
     Agreement").  Under that Agreement, McKesson was granted (1) certain
     information and inspection rights, and rights to register shares of Company
     Common Stock under the Securities Act; (2) the right to elect two directors
     of IMS if the Board of Directors consisted of eight directors, or at least
     20% of the directors if the Board of Directors consisted of more than eight
     directors; (3) the right to designate one member of the IMS Operating
     Company Advisory Board and one member of the IMS Business Development Group
     Advisory Board; (4) during the period the McKesson Sponsorship Agreement
     remains in effect, the right to have IMS ensure that any joint venture
     agreements, or other agreements for the operation of the IMS Networks,
     provide McKesson access for the McKesson Product Lines to all Subscribers
     designated by McKesson, and for such access to have the benefit of certain
     preferred pricing provisions under the McKesson Sponsorship Agreement; (5)
     the right to cause IMS to spend up to a total of $500,000 for regional or
     technical development efforts as directed by McKesson; (6) during the
     period that the McKesson Sponsorship Agreement is in effect, the right to
     approve the introduction by IMS of any Prescription Benefit Management
     Services and the terms thereof; and (7) during the period that the McKesson
     Sponsorship Agreement is in effect, the right to approve, subject to
     certain exceptions, any joint venture agreement, or other agreement, for
     the operation of an IMS Network with any entity engaged in a business
     defined as a McKesson Product Line.

              Under the McKesson Stockholder's Rights Agreement, McKesson was
     granted a right of first offer to purchase all or a portion of "New
     Securities" which IMS may, from time to time, propose to sell.  For this
     purpose, "New Securities" includes, subject to certain exceptions, any
     capital stock and rights, options or warrants to purchase capital stock and
     securities convertible into capital stock.  The right of first offer does
     not apply to:  (i) sales to persons who were directors, officers, employees
     or shareholders as of January 6, 1994; (ii) sales of up to 15% of New
     Securities per investor to accredited individual investors; (iii) sales of
     up to 15% of New Securities per investor to institutional investors; (iv)
     any sales of up to 5% per investor of New Securities to significant IMS
     customers, which means customers generating at least 5% of IMS's annual
     revenues; or (v) any sales of up to 15% per investor of New Securities to
     potential investors which the IMS Board of Directors identifies as
     potential strategic partners of IMS.

              However, the exceptions set forth in clauses (i) through (v) do
     not apply to potential investors which are engaged to any degree, and for
     clauses (ii) and (iii) have invested to any degree, in any of the
     Businesses defined as McKesson Product Lines (as defined in the McKesson
     Sponsorship Agreement).  In addition, if IMS sells New Securities to a
     purchaser pursuant to clauses (i) through (v), McKesson has the right to
     purchase capital stock on the same terms as those offered to such purchaser
     in such amounts as will preserve McKesson's percentage of equity ownership
     in IMS.  Furthermore, McKesson has approval rights for prospective
     purchasers of New Securities to the extent that they are engaged in any of
     the businesses defined as McKesson Product Lines.

              Nothing in the right of first offer is to constrain IMS's ability,
     at the sole discretion of its Board  of Directors, to effect a public
     offering of stock.  The right of first offer expires upon, and shall not be
     applicable to, the first sale of Company Common Stock to the public
     pursuant to a registration

                                       24

 
     statement filed under the Securities Act involving at least 15% of IMS's
     aggregate outstanding shares after giving effect to the public offering and
     resulting in gross proceeds of at least $15 million.

              McKesson's right of first offer and approval rights described
     above are now claimed by Lilly's subsidiary, PCS.  IMS has asserted (and
     PCS has disagreed) that certain of McKesson's rights under the McKesson
     Stockholder's Rights Agreement could be asserted only by McKesson and that
     such rights would not be enforceable by Lilly or PCS.  If the Merger is
     effected, this potential dispute will be avoided.

         Lilly Loans to IMS

              In accordance with the Term Sheet and Merger Agreement, on July
     12, 1995, July 27, 1995 and August 28, 1995, Lilly loaned IMS $3 million,
     $1 million and $1 million, respectively.  Each loan is due and payable upon
     the earlier of any breach of the Merger Agreement by IMS (subject to
     certain rights of IMS to cure such breach) or July 1, 1996 with interest at
     the annual rate of 10%.  Each loan is subordinated to the indebtedness
     outstanding on the date of such loan and is secured by a pledge of most of
     the assets of IMS, including shares of subsidiaries.

              Pursuant to the Merger Agreement, Lilly has agreed to continue to
     advance to IMS from time to time (subject to certain exceptions), at IMS's
     request, funds, as required to fund the then current cash requirements of
     IMS but not to exceed $1.5 million per month.  Each such advance will be on
     terms and conditions that are substantially similar to those contained in
     the earlier loans.  IMS and Lilly currently anticipate that the aggregate
     amount of such loans will be approximately $_______________ by the date of
     the Special Meeting.

     ACCOUNTING TREATMENT OF THE MERGER

              The Merger will be accounted for as a purchase in accordance with
     GAAP.  Accordingly, a determination of the fair market value of IMS's
     assets and liabilities will be made in order to allocate the purchase price
     of the assets acquired and the liabilities assumed.  From and after the
     Effective Date, IMS's results of operations will be included in Lilly's
     consolidated results of operation.

     INTERESTS OF CERTAIN PERSONS IN THE MERGER

              Under the Merger Agreement, at the Effective Date, nine senior
     executives of IMS will each be offered severance agreements with Lilly
     pursuant to which Lilly will agree not to reduce such executive's rates of
     compensation or benefits payable to such persons for one year from the
     Effective Date and will pay an amount equal to one year's base salary if
     during the one year period such person's employment is terminated by action
     of IMS for any reason other than for cause or if such person resigns
     because he is required by IMS to relocate to any office not within
     reasonable commuting distance from his place of residence.  See "THE MERGER
     AGREEMENT - Certain Understandings and Agreements."

              Certain provisions of the employment arrangement of Kevin R. Green
     with IMS require IMS to pay to Mr. Green an amount equal to two years'
     salary under certain circumstances in the event of a change of control of
     IMS, such as the Merger.  See "MANAGEMENT OF IMS - Certain Transactions."
     Directors and officers of IMS will be afforded certain future rights to
     indemnification for liabilities which may arise from service as an officer
     or director of IMS prior to the Merger.

     NO STOCK EXCHANGE OR NASDAQ LISTING; RESALES OF SERIES D PREFERRED STOCK
     AND SERIES B PREFERRED STOCK

              The shares of Series D Preferred Stock will not be listed on any
     stock exchange or traded on the National Association of Securities Dealers
     Automated Quotations ("NASDAQ") National Market System.  In addition, it is
     likely that there will be fewer than 300 holders of Series D Preferred
     Stock and therefore that IMS will not be subject to the reporting
     requirements of Section 12(g) or 15(d) of the

                                       25

 
     Exchange Act once it has filed its first annual report on Form 10-K in
     March 1996.  Also, any shares that the holders elect to make subject to
     Put/Call Agreements will be subject to contractual restrictions on
     transfer, as described below under "PUT/CALL AGREEMENTS."  Accordingly, it
     is not expected that any trading market will develop for shares of Series D
     Preferred Stock.

              Subject to the foregoing, the shares of Series D Preferred Stock
     to be issued in the Merger to persons who elect to receive such shares, and
     any shares that are subsequently issued upon conversion of Series B
     Preferred Stock, will be freely transferable, except for any shares
     received by "affiliates" of IMS, as that term is defined in Rule 405 under
     the Securities Act at the time of the Merger.

              IMS affiliates may resell such shares of Series D Preferred Stock
     only in compliance with the resale provisions of Rule 145 under the
     Securities Act or as otherwise permitted by the Securities Act.  Under Rule
     145, during the first two years following the Merger, such shares could be
     sold publicly by an IMS affiliate only if IMS is then making publicly
     available adequate current information pursuant to Rule 144(c), and if the
     number of shares to be sold, together with the number of shares sold by
     such affiliate within the three months preceding such sale, does not exceed
     one percent of the outstanding shares of Series D Preferred Stock.  After
     such two years, such shares could be sold publicly without compliance with
     the volume limitations if at the time of sale the seller is not an
     affiliate of IMS provided that IMS continues to make available the
     information required by Rule 144(c).  It is not expected that IMS will be
     making such information publicly available except during the limited period
     that it will be subject to the reporting requirements of Section 15(d) of
     the Exchange Act.  After a period of three years following the Merger, such
     shares could be sold publicly without compliance with the volume and
     current public information requirements noted above if at the time of sale
     the seller is not, and has not been for at least three months, an affiliate
     of IMS.  Currently, the only persons expected to be "affiliates" of IMS at
     the time of the Merger are the officers and directors of IMS, certain
     members of their families, and certain affiliated entities.  Persons who
     continue to be affiliates of IMS after the Merger would remain subject to
     the requirement to make public resales in accordance with all of the
     provisions of Rule 144 while they retain that status.

              Shares of Series D Preferred Stock that are issued subsequent to
     the Merger upon the conversion of Company Options or Company Warrants may
     be subject to transfer restrictions under the securities laws, depending on
     whether the sale of those shares to the holder was registered under the
     Securities Act, whether such holder is then an affiliate of IMS and whether
     IMS is then making publicly available adequate current information.

              Any shares of Series B Preferred Stock that remain outstanding
     following the Merger will be subject to the same limitations on transfer
     described above that apply to Series D Preferred Stock.  In addition, the
     Series B Preferred Stock is currently held by only 23 persons and IMS
     anticipates that a substantial number of these holders will elect to
     exchange their shares of Series B Preferred Stock for the Merger
     Consideration.  Seven IMS directors who collectively own more than a
     majority of the shares of Series B Preferred Stock have already committed
     to do so.  Accordingly, IMS does not expect that any trading market for the
     shares of Series B Preferred Stock will develop.

     GOVERNMENTAL AND REGULATORY APPROVALS

              In connection with exercises of Warrants, Lilly filed a
     Notification with the Federal Trade Commission and the Department of
     Justice pursuant to the HSR Act on February 27, 1995, seeking clearance to
     acquire 50% or more of the voting stock of IMS.  No second request for
     additional information was received and the mandatory waiting period
     expired on March 29, 1995.  As a result, no further action is required
     under the HSR Act in connection with the Merger provided that the Merger is
     completed by March 29, 1996.

     MARKET PRICES

              IMS.  No public market exists for the Company Common Stock or the
     Series B Preferred Stock and, accordingly, market price information is not
     available for such stock.

               Lilly.  The shares of Lilly Common Stock are listed and
     principally traded on the New York Stock Exchange, Inc. (the "NYSE").  On
     August 2, 1995, the last full trading day prior to the first public
     announcement of the Merger, the reported closing price per share of Lilly
     Common Stock on the NYSE Composite Tape was $77.  On ________, 1995, the
     reported closing price per share of Lilly Common Stock on the NYSE
     Composite Tape was $______.

                              THE MERGER AGREEMENT

              The following is a brief summary of the Merger Agreement, a copy
     of which is included as an exhibit to the Registration Statement of which
     this Proxy Statement-Prospectus is a part and is incorporated herein by
     reference. Such summary is qualified in its entirety by reference to the
     Merger Agreement.

     THE MERGER

              The Merger Agreement provides that, upon the terms and subject to
     the satisfaction or waiver of certain conditions set forth therein,
     Subsidiary will be merged into IMS, the separate corporate existence of
     Subsidiary will cease and IMS will continue as the surviving corporation.
     The Merger will become effective on the Effective Date upon the filing with
     the Secretary of State of the State of Colorado of duly executed Articles
     of Merger in accordance with Section 7-111-105 of the Colorado Business
     Corporation Act.

              Pursuant to the Merger, (i) each outstanding share of Company
     Common Stock (other than shares held by IMS as treasury shares, shares
     owned by Lilly or any subsidiary of Lilly, or shares as to which
     dissenters' rights have been perfected under Colorado law) will be
     converted into, at the holder's election, either (a) $8.00 in cash, without
     interest, or (b) one share of Series D Preferred Stock, (ii) each
     outstanding share of Series B Preferred Stock (other than shares as to
     which dissenters' rights have been perfected under Colorado law) will
     either (a) be converted into, at the holder's election, either (1) $5.33 in
     cash, without interest, plus an amount, in cash, without interest, equal to
     the amount of all accrued and unpaid dividends on such share of Series B
     Preferred Stock to the Effective Date or (2) two-thirds of a share of
     Series D Preferred Stock plus an amount, in cash, without interest, equal
     to the amount of all accrued and unpaid dividends on such share of Series B
     Preferred Stock to the Effective Date or (b) remain outstanding (with the
     amended preferences, limitations and rights set forth in the Articles of
     Incorporation of the surviving corporation), (iii) each outstanding share
     of Series C Preferred Stock of the Company will be converted into one share
     of common stock of the surviving corporation and (iv) each share of common
     stock of Subsidiary then issued and outstanding will be converted into and
     become 120,000 shares of common stock of the surviving corporation.

              No fractional shares of Series D Preferred Stock will be issued
     but in lieu thereof cash payments will be made to each holder of Series B
     Preferred Stock in respect of any fractional share that would otherwise be
     issuable to such holder (after aggregating all of the shares of Series D
     Preferred Stock to be issued to such holder) in an amount equal to such
     fractional part of a share of Series D Preferred Stock multiplied by $8.00.
     No such holder shall be entitled to dividends, voting rights or any other
     shareholder right in respect of any fractional share.

              In addition, each holder of Company Common Stock, Series B
     Preferred Stock, Company Options or Company Warrants will be offered the
     right to enter into a Put/Call Agreement with Lilly with respect to any or
     all of the shares of Series D Preferred Stock that such holder may acquire.
     See "PUT/CALL AGREEMENTS."

              If the Merger is adopted by the requisite vote of the shareholders
     of IMS and certain other conditions to the Merger are satisfied or waived,
     the Closing will be held promptly thereafter, or if later, on the day three
     business days following the date on which the last of the required
     conditions to the Closing has been fulfilled or waived, or at such other
     time as is agreed upon by Lilly and IMS.

                                       28

 
     DESCRIPTION OF ELECTION PROCEDURES

              Subject to the election procedures set forth below, each record
     holder immediately prior to the Effective Date of shares of Company Common
     Stock or Series B Preferred Stock (other than Lilly or any subsidiary of
     Lilly) will be entitled (i) to make a Cash Election for any or all of such
     shares, or (ii) to make a Stock Election for any or all of such shares.  In
     addition, each record holder immediately prior to the Effective Date of
     shares of Series B Preferred Stock will be entitled to make an Election to
     Retain Series B Preferred Stock.

              Elections must be made by mailing to the Exchange Agent a duly
     completed Form of Election.  To be effective, a Form of Election must be
     properly completed, signed and submitted to the Exchange Agent and (except
     if an Election to Retain Series B Stock is made or deemed to have been
     made), accompanied by the certificates representing the shares of Company
     Common Stock or Series B Preferred Stock as to which the election is being
     made (or by an appropriate guarantee of delivery of such certificates by a
     commercial bank or trust company in the United States or a member of a
     registered national securities exchange or the National Association of
     Securities Dealers, Inc.).  All duly completed Forms of Election must be
     received by the Exchange Agent by the Election Deadline.  Lilly will have
     the discretion, which it may delegate in whole or in part to the Exchange
     Agent, to determine whether Forms of Election have been properly completed,
     signed and submitted or revoked and to disregard immaterial defects in
     Forms of Election.  The decision of Lilly (or the Exchange Agent) in such
     matters will be conclusive and binding.  Neither Lilly nor the Exchange
     Agent will be under any obligation to notify any person of any defect in a
     Form of Election submitted to the Exchange Agent.

              A HOLDER OF COMPANY COMMON STOCK OR SERIES B PREFERRED STOCK WHO
     DOES NOT SUBMIT A PROPERLY COMPLETED AND SIGNED FORM OF ELECTION WHICH IS
     RECEIVED BY THE EXCHANGE AGENT PRIOR TO THE ELECTION DEADLINE WILL BE
     DEEMED TO HAVE MADE A CASH ELECTION, IN THE CASE OF A HOLDER OF COMPANY
     COMMON STOCK, AND AN ELECTION TO RETAIN SERIES B PREFERRED STOCK, IN THE
     CASE OF A HOLDER OF SERIES B PREFERRED STOCK.  If Lilly or the Exchange
     Agent determines that any purported Cash Election, Stock Election or
     Election to Retain Series B Preferred Stock was not properly made, the
     shareholder making such purported Election will be deemed to have made a
     Cash Election, in the case of a holder of Company Common Stock, and an
     Election to Retain Series B Preferred Stock, in the case of Series B
     Preferred Stock.

              An election may be revoked, but only by written notice received by
     the Exchange Agent prior to the Election Deadline.  Upon any such
     revocation, unless a duly completed Form of Election is thereafter
     submitted in accordance with the procedures described herein, such shares
     will be deemed to be Cash Election shares, in the case of Company Common
     Stock, and Election to Retain Series B Preferred Stock shares, in the case
     of Series B Preferred Stock.

     PROCEDURES FOR EXCHANGE OF CERTIFICATES

              IMS SHAREHOLDERS THAT WISH TO SUBMIT A FORM OF ELECTION SHOULD
     DELIVER THEIR STOCK CERTIFICATES TOGETHER WITH SUCH FORM OF ELECTION OR
     PROVIDE FOR, AND COMPLY WITH THE REQUIREMENTS OF, GUARANTEED DELIVERY.

              As soon as reasonably practicable after the Effective Date (unless
     the Company, prior to the Effective Date, agrees to an earlier mailing),
     Lilly will instruct the Exchange Agent to mail to each holder of record
     (other than (x) holders of dissenting shares or (y) Lilly or any subsidiary
     of Lilly) of a certificate or certificates which immediately prior to the
     Effective Date evidenced outstanding shares of Company Common Stock or
     Series B Preferred Stock (the "Certificates"), (i) a letter of transmittal,
     (ii) instructions for use in effecting the surrender of the Certificates in
     exchange for certificates evidencing shares of Series D Preferred Stock or
     cash and (iii) a Form of Election.  With respect to a holder of a
     Certificate, other than a Certificate representing Series B Preferred Stock
     for which a valid Election to

                                       29

 
     Retain Series B Preferred Stock, or a deemed Election to Retain Series B
     Preferred Stock, has been made, upon surrender of a Certificate for
     cancellation to the Exchange Agent together with such letter of
     transmittal, duly executed and such other customary documents as may be
     required pursuant to such instructions, the holder of such Certificate will
     be entitled to receive in exchange therefor (A) certificates evidencing
     that number of shares of Series D Preferred Stock which such holder has the
     right to receive in respect of the shares of Company Common Stock or Series
     B Preferred Stock formerly evidenced by such Certificate, (B) cash which
     such holder is entitled to receive, (C) cash in lieu of a fractional share
     of Series D Preferred Stock which such holder is entitled to receive and
     (D) any dividends or other distributions to which such holder is entitled,
     and the Certificate so surrendered will be cancelled; provided, however,
                                                           --------  ------- 
     that as to any holder who executed a Put/Call Agreement with respect to any
     shares of Series D Preferred Stock, the certificates evidencing such shares
     will be delivered to the Escrow Agent under the Escrow Agreement
     contemplated by the Put/Call Agreements.  In the event of a transfer of
     ownership of shares which is not registered in the transfer records of the
     Company, for transferees who elect to receive the Merger Consideration, a
     certificate evidencing the proper number of shares of Series D Preferred
     Stock and/or cash may be issued and/or paid to that transferee if the
     Certificate evidencing such transferred shares is presented to the Exchange
     Agent, accompanied by all documents required to evidence and effect such
     transfer and by evidence that any applicable stock transfer taxes have been
     paid.  Until surrendered, each Certificate, other than a Certificate
     representing shares of Series B Preferred Stock for which a valid Election
     to Retain Series B Preferred Stock, or a deemed Election to Retain Series B
     Stock, has been made, will be deemed at any time after the Effective Date
     to evidence only the right to receive upon such surrender the appropriate
     Merger Consideration.

              No dividends or other distributions declared or made with respect
     to Series D Preferred Stock will be paid to the holder of any unsurrendered
     Certificate with respect to the shares of Series D Preferred Stock
     evidenced thereby, and no other part of the Merger Consideration will be
     paid to any such holder until the holder of such Certificate surrenders
     such Certificate.  No interest will accrue or be paid on the Merger
     Consideration.

              All shares of Series D Preferred Stock issued and cash paid upon
     conversion of the shares of Company Common Stock or Series B Preferred
     Stock in accordance with the terms of the Merger Agreement will be deemed
     to have been issued or paid in full satisfaction of all rights pertaining
     to such shares of Company Common Stock or Series B Preferred Stock.  On the
     Effective Date, each holder of a certificate or certificates up to that
     time representing shares of Company Common Stock or Series B Preferred
     Stock, other than a holder of a certificate or certificates representing
     Series B Preferred Stock for which a valid Election to Retain Series B
     Preferred Stock, or a deemed Election to Retain Series B Preferred Stock,
     has been made, will cease to have any rights as a shareholder of the
     Company and will not be deemed to be a shareholder of, or be entitled to
     any rights of a shareholder with respect to, the surviving corporation but
     thereafter will have only the rights described herein.

              Neither Lilly nor IMS will be liable to any shareholder for any
     shares or cash in respect of shares delivered to a public official pursuant
     to any applicable abandoned property, escheat or similar law.  In the event
     any Certificate has been lost, stolen or destroyed, upon the making of an
     affidavit of that fact by the person claiming such certificate to be lost,
     stolen or destroyed and, if required by the Company, the posting by such
     person of a bond in a form and an amount specified by Lilly and reasonably
     acceptable to the Company as indemnity against any claim that may be made
     against it with respect to such Certificate, the Exchange Agent will issue
     in exchange for such lost, stolen or destroyed Certificate the Merger
     Consideration, without any interest or dividends or other payments thereon,
     upon due surrender of and deliverable in respect of such Certificate
     pursuant to the Merger Agreement.

              IMS will be entitled to deduct and withhold from the consideration
     otherwise payable pursuant to the Merger Agreement such amounts as IMS is
     required to deduct and withhold with respect to the making of such payment
     under the Internal Revenue Code (the "Code"), or any provision of state,
     local or foreign tax law.

                                       30

 
              After the Effective Date, there will be no transfers on the stock
     transfer books of the Company of any shares of Company Common Stock, other
     than any shares of Company Common Stock held by Lilly or any subsidiary of
     Lilly, or any shares of Series B Preferred Stock which were outstanding
     immediately prior to the Effective Date other than shares of Series B
     Preferred Stock for which a valid Election to Retain Series B Stock, or a
     deemed Election to Retain Series B Stock, has been made.  If, after the
     Effective Date, Certificates formerly representing shares of Company Common
     Stock which were outstanding immediately prior to the Effective Date, other
     than any shares of Company Common Stock held by Lilly or any subsidiary of
     Lilly, or shares of Series B Preferred Stock which were outstanding
     immediately prior to the Effective Date (for which a valid Election to
     Retain Series B Stock has not been made or deemed to be made) are presented
     to the Company or the Exchange Agent, they will be cancelled and (subject
     to applicable abandoned property, escheat and similar laws and, in the case
     of Dissenting Shares, subject to applicable law) exchanged for Merger
     Consideration.

              SHAREHOLDERS SHOULD NOT SEND IN ANY CERTIFICATES WITH THEIR
                                  PROXY CARDS

     EFFECT OF THE MERGER ON COMPANY OPTIONS AND COMPANY WARRANTS

              Each holder of outstanding Company Options on the Effective Date
     will have the right immediately following the Merger to elect to have such
     Company Options converted, in whole or in part, into (i) the right to
     receive $8.00 in cash, without interest, for each share of Company Common
     Stock for which such Company Option was exercisable as of the Effective
     Date (except that in lieu of paying the exercise price of such Company
     Option, the holder thereof may elect to net the amount of the exercise
     price against and to that extent reduce the $8.00 otherwise receivable), or
     (ii) the right to purchase for the same exercise price one share of Series
     D Preferred Stock for each share of Company Common Stock for which such
     Company Option was exercisable as of the Effective Date, or (iii) fully
     vested Lilly Options to acquire shares of Lilly Common Stock under the 1994
     Lilly Stock Plan.  Any election pursuant to clause (ii) above must be for a
     whole number of shares of Series D Preferred Stock.

              Each Company Option for which an election to convert into Lilly
     Options is duly made will be converted as follows:  each such Company
     Option will become a Lilly Option with an exercise price that bears the
     same relationship to the fair market value of Lilly Common Stock on the
     Effective Date (as such value is determined under the 1994 Lilly Stock
     Plan) as the exercise price of the Company Option bears to $8.00, and the
     number of shares subject to the Lilly Option will be the number that
     results in the Lilly Option having the same aggregate "spread" as existed
     on the Company Option.  (For this purpose, the aggregate "spread" on the
     Company Option shall be (x) the difference between $8.00 and the exercise
     price of the Company Option multiplied by (y) the number of shares subject
     to the Company Option; and the aggregate "spread" on the Lilly Option shall
     be (x) the difference between the exercise price of the Lilly Option and
     the fair market value of Lilly Common Stock on the Effective Date
     multiplied by (y) the number of shares subject to the Lilly Option.)  By
     way of illustration, if a holder owns a Company Option on 100 shares of
     Company Common Stock at an exercise price of $2.00 per share, then the
     aggregate "spread" is $600, i.e., ($8.00 - $2.00) x 100.  If the fair
     market value of Lilly Common Stock on the Effective Date is $80 per share,
     the exercise price of the Lilly Option will be $20, i.e., 2/8 = 20/80, and
     the number of Lilly shares subject to the Lilly Option will be 10, i.e.,
     the aggregate "spread" of $600 divided by the per share "spread" of $60
     under the Lilly Option.  The other terms and conditions of the Lilly Option
     will, to the extent practicable and permitted under the 1994 Lilly Stock
     Plan, be substantially the same as the Company Option for which the Lilly
     Option is substituted.  Notwithstanding the foregoing, no Lilly Option to
     purchase a fractional share of Lilly Common Stock will be issued to a
     holder of a Company Option.  In lieu thereof, a cash payment will be made
     in respect of any such Lilly Option that would otherwise be issuable to
     such holder (after aggregating all of the Lilly Options to be issued to
     such holder) in an amount equal to such fractional part of a Lilly Option
     multiplied by the "spread" on a Lilly Option for one share of Lilly Common
     Stock.

                                       31

 
              Each holder of outstanding Company Warrants on the Effective Date
     (other than warrants owned by Lilly or any of its subsidiaries) will have
     the right to elect to have such Company Warrants converted into (i) the
     right to receive $8.00 in cash, without interest, for each share of Company
     Common Stock for which such Company Warrant was exercisable as of the
     Effective Date (except that in lieu of paying the exercise price of such
     Company Warrant, the holder thereof may elect to net the amount of the
     exercise price against and to that extent reduce the $8.00 otherwise
     receivable) or (ii) the right to purchase for the same exercise price one
     share of Series D Preferred Stock for each share of Company Common Stock
     for which such Company Warrant was exercisable as of the Effective Date.
     Each warrant to purchase Series C Preferred Stock owned by Lilly or any of
     its subsidiaries will, on the Effective Date, be converted into the right
     to purchase one share of common stock of the surviving corporation for each
     share for which such warrant was exercisable as of the Effective Date.

              A Form of Election for use by holders of Company Options and
     Company Warrants will be mailed separately to holders thereof following the
     Merger.  To be effective, a Form of Election must be properly completed,
     signed and received by the Exchange Agent by the Election Deadline.
     HOLDERS OF COMPANY OPTIONS OR COMPANY WARRANTS WHO DO NOT PROPERLY COMPLETE
     AND RETURN THE FORM OF ELECTION BY THE ELECTION DEADLINE WILL BE DEEMED TO
     HAVE ELECTED TO RECEIVE THE LILLY OPTIONS, IN THE CASE OF A COMPANY OPTION,
     OR THE RIGHT TO PURCHASE SHARES OF SERIES D PREFERRED STOCK, IN THE CASE OF
     COMPANY WARRANTS.

              In addition, each holder of a Company Option or a Company Warrant
     will be offered the right to enter into a Put/Call Agreement with Lilly
     with respect to any and all of the shares of Series D Preferred Stock that
     such holder may acquire.  See "PUT/CALL AGREEMENTS."

         Certain Other Agreements

              Pursuant to the Merger Agreement, IMS has agreed to take all
     action necessary in accordance with applicable law and its Articles of
     Incorporation and By-Laws to convene the Special Meeting as promptly as
     practicable to consider and vote upon the approval and adoption of the
     Merger Agreement and to consider and vote upon such other matters as may be
     necessary to effectuate the transactions provided for therein.  The Board
     of Directors of IMS has resolved to recommend, and except as the Board of
     Directors determines in good faith, based on the advice of outside counsel
     to IMS, is required to satisfy its fiduciary duties, IMS has agreed that
     the Board of Directors will continue to recommend, and will take all lawful
     action to solicit proxies for and otherwise obtain, such approval and
     adoption.  Lilly has agreed to vote, or cause its subsidiaries to vote, any
     shares of capital stock of the Company held by Lilly or such subsidiaries
     and entitled to vote in favor of the approval and adoption of the Merger
     Agreement and the transactions contemplated thereby.

              IMS has agreed that neither it nor any of its subsidiaries or
     Controlled Affiliated Entities or any of their respective employees, agents
     or representatives (including, without limitation, its investment bankers)
     will, directly or indirectly, solicit or enter into any agreement or
     understanding with, or otherwise encourage inquiries or proposals from, or
     furnish any non-public information concerning IMS or any subsidiary or
     affiliated entity to, any person or entity other than Lilly or a
     representative thereof with respect to the acquisition (by purchase, merger
     or otherwise) of any or all of the capital stock of IMS or any subsidiary
     or affiliated entity or any or all of the assets of IMS or any of its
     subsidiaries or affiliated entities

                                       34

 
     or any other material corporate transactions relating to IMS or its
     subsidiaries or affiliated entities; provided, however, that IMS may engage
                                          --------  -------                     
     in discussions or negotiations with a third party who, unsolicited, seeks
     to initiate such discussions or negotiations and may pursuant to
     confidentiality agreements furnish such party information concerning IMS
     and its business, properties and assets, provided that the Board of
     Directors of IMS will conclude in good faith on the basis of the advice of
     IMS's outside counsel that such action is necessary to satisfy the
     fiduciary duties of the Board of Directors.  Should IMS receive an
     unsolicited offer for such a transaction, or obtain information that such
     an offer is likely to be made, IMS has agreed to provide Lilly with prompt
     notice thereof, including the identity of the prospective offeror and the
     terms and conditions of such offer.

              Lilly, Subsidiary and the Company have agreed to use, and the
     Company has agreed to cause its Controlled Subsidiaries and Controlled
     Affiliated Entities to use, their best efforts to take, or cause to be
     taken, all action, and to do, or cause to be done, all things necessary,
     proper or advisable under applicable laws and regulations to consummate and
     make effective the Merger, including, without limitation, using their
     best efforts to satisfy the conditions to the Merger described under
     " -Conditions to the Merger" below.

              Lilly has agreed to advance to the Company from time to time,
     subject to certain conditions, at the Company's request, funds, as required
     to fund the then current cash requirements of the Company but not to exceed
     $1.5 million per month. See "SPECIAL FACTORS TO BE CONSIDERED -Prior
     Agreements/Relationships of the Parties - Lilly Loans to IMS."

              In addition, Lilly has agreed to offer to enter into agreements at
     or prior to the Closing with specified members of IMS's management under
     which the Company would agree not to reduce such person's respective rates
     of compensation and benefits for the one year period beginning on the
     Effective Date and Lilly would pay, or cause the Company to pay, such
     person an amount equal to one year's base salary if during the one-year
     period beginning on the Effective Date such person's employment is
     terminated by action of the Company for any reason other than for cause or
     such person resigns because he is required by the Company to relocate to
     any office not within reasonable commuting distance of his or her
     residence.  Such agreement will also contain a non-compete provision for
     the period during which such person is receiving such severance payments.
     See "SPECIAL FACTORS TO BE CONSIDERED - Interests of Certain Persons in the
     Merger."

              Lilly has agreed that it will not, prior to the third anniversary
     of the Closing, engage in or cause, or otherwise permit to occur, a merger
     (other than the Merger) or other extraordinary transaction that would
     result in the holders of the Series D Preferred Stock being deemed for
     Federal income tax purposes to have sold their shares of Series D Preferred
     Stock in such merger or other extraordinary transaction.

     CONDITIONS TO THE MERGER

              The respective obligations of each of Lilly, Subsidiary and IMS to

     the Effective Date, of certain conditions, including:  (i) the approval of
     the Merger by IMS shareholders; (ii) the receipt of all consents,

     threatened by any public authority or private person before any court,
     agency or governmental or administrative body or other entity of competent
     jurisdiction which, in the reasonable opinion of Lilly or IMS, creates any
     substantial likelihood that the consummation of the Merger will be
     restrained, enjoined or otherwise prevented or that any material damages
     will be recovered or other material relief obtained as a result of the
     Merger or as a result of any agreement entered

                                       35

     the Merger Agreement, which in the reasonable opinion of Lilly creates any
     reasonable possibility of material interference with the ability of Lilly,
     through representatives designated by it, to manage following the Effective
     Date the business theretofore conducted by IMS and its subsidiaries; (vii)
     the receipt by Lilly on or prior to the Effective Date of a statement
     pursuant to Section 1445(b)(2) of the Code and Treasury Regulations Section
     1.1445-2(c)(3) thereunder, certifying that the shares of capital stock of

                              PUT/CALL AGREEMENTS

              The following is a brief summary of the terms of the form of
     Put/Call Agreement, a copy of which is attached as Appendix B to this Proxy
     Statement-Prospectus and is incorporated herein by reference.  Such summary
     is qualified in its entirety by reference to the Put/Call Agreement.

     GENERAL

              Lilly will offer each holder of Company Common Stock, Series B
     Preferred Stock, Company Options or Company Warrants (a "Holder") the
     opportunity to enter into a Put/Call Agreement that would apply to any or
     all of the Holder's shares of Series D Preferred Stock as the Holder may
     elect (the "Subject Shares").

     PUT RIGHT

              Under a Put/Call Agreement, a Holder will have the right to
     require Lilly to purchase any or all of the Holder's Subject Shares during
     each of two Put Periods at a price of $8.00 per share, plus any unpaid
     dividends accrued to the purchase date (the "Purchase Price").

              The initial Put Period shall be a period of at least 10 business
     days beginning on the first anniversary of the Merger; the second Put
     Period shall be a period of at least 10 business days beginning
     approximately 30 months after the Merger.  However, Lilly will have the
     right to defer commencement of a Put Period, or to suspend a Put Period
     that has commenced, or to defer the making of purchases pursuant to the
     exercise of a Put in order to permit compliance with all applicable laws;
     provided, however, that Lilly will use its commercially reasonable efforts
     --------  -------                                                         
     to cause such compliance so as to avoid or minimize any such deferral or
     suspension, except that if commencement or continuation of a Put Period, or
     the making of purchases pursuant to the exercise of a Put, would require
     the disclosure to the Holder of information about IMS or Lilly that, in
     Lilly's reasonable judgment, it is not then in the best interests of IMS or
     Lilly to disclose, Lilly may, in its discretion, defer the commencement of,
     or may suspend, the Put Period or defer such purchases, for up to 90 days.

     CALL RIGHT

              Under a Put/Call Agreement, Lilly will have the right to require a
     Holder to sell any or all of the Holder's Subject Shares to Lilly at the
     Purchase Price in whole at any time or in part from time to time after the
     third anniversary of the Merger.

     ESCROW

              The stock certificates representing the Subject Shares will bear a
     restrictive legend and must be deposited into an escrow accompanied by an
     undated stock power endorsed in blank relating to the Subject Shares.  To
     that end, the Exchange Agent will, following the Merger, deliver directly
     to the Escrow Agent the certificates for any Subject Shares issued in the
     Merger.  The escrowed certificates will be held in the escrow pending
     possible purchase by Lilly pursuant to the put/call rights, but if for any
     reason the Escrow Agreement has not been terminated by December 31, 2001,
     the Escrow Agent shall promptly release the escrowed shares to the Holders.

                                       38

 
     TRANSFERS OF SUBJECT SHARES

              The Holder will have the right to sell, assign, donate, pledge or
     otherwise transfer or encumber any or all of the Subject Shares and any
     related rights and obligations under the Put/Call Agreement only with
     Lilly's prior written consent.  Lilly will grant such consent provided
     that:

              (i) the transferee shall have executed and delivered an agreement
          reasonably satisfactory to Lilly confirming that the Subject Shares
          being transferred will remain subject to the Put/Call Agreement;

              (ii) the certificates for the Subject Shares being transferred
          remain deposited in the escrow and the transferee shall have executed
          and delivered to the Escrow Agent an undated stock power for those
          Subject Shares (subject to certain exceptions where the transfer is a
          bona fide pledge);

              (iii)  Lilly is reasonably satisfied that the transfer will comply
          with all applicable securities laws and other legal requirements and
          will not result in the outstanding Series D Preferred Stock being held
          of record by 500 or more persons within the meaning of Section 12(g)
          of the Exchange Act, as amended, and the rules and regulations
          thereunder.

     NO RESTRICTIONS ON LILLY

              The existence of any Put/Call Agreement will not impair or
     restrict in any way Lilly's right, following the Merger, to transfer all or
     any of its interest in IMS or to cause IMS to merge, sell its assets or
     engage in other extraordinary transactions, including, without limitation,
     transactions that would result in the cashing out of Series D Preferred
     Stock or the exchange of Series D Preferred Stock for other securities,
     except that prior to the third anniversary of the Merger Lilly will not
     cause IMS to engage in a merger or other extraordinary transaction that
     would result in a Holder's being deemed for Federal income tax purposes to
     have sold Subject Shares in such merger or other extraordinary transaction.
     Lilly will represent that, as of the date of the Put/Call Agreement, it has
     no present intention to cause IMS to engage in such a merger or other
     extraordinary transaction prior to the fifth anniversary of the Merger.

              If pursuant to a merger, consolidation, recapitalization,
     reorganization, sale of substantially all of the assets or other such
     transaction involving IMS, the outstanding shares of Series D Preferred
     Stock are converted into or exchanged for cash, property or securities of
     IMS or any other issuer, then the put and call rights shall apply to such
     cash, property or securities and the Purchase Price and other terms of the
     Put/Call Agreement shall be subject to appropriate adjustment, so as to
     preserve unchanged to the fullest extent possible the rights and
     obligations of the parties to the Put/Call Agreement.

          SUBMISSION TO JURISDICTION

              Any action or proceeding arising out of a Put/Call Agreement may
     be heard and determined by any state or federal court sitting in the State
     of Colorado.

               AMENDMENT TO THE ARTICLES OF INCORPORATION OF IMS

              Approval of the Merger by IMS shareholders will include approval
     of an amendment to the Articles of Incorporation of IMS (as amended, the
     "New Charter") set forth in the Articles of Merger, effective upon
     consummation of the Merger, as described below.  The following is a summary
     of such amendments, and is qualified in its entirety by reference to the
     Articles of Merger which are attached hereto as Appendix A to this Proxy
     Statement-Prospectus.  For a more complete description of the preferences,
     limitations and relative rights of the capital stock of IMS following the
     Merger, see "DESCRIPTION OF CAPITAL STOCK OF IMS."

     CAPITALIZATION

              The New Charter changes the total authorized capital of IMS from
     25,000,000 shares of common stock, without par value, and 7,000,000 shares
     of preferred stock, $0.01 par value, to 20,000,000 shares of common stock,
     without par value, 2,000,000 shares of Series B Preferred Stock, $1.00 par
     value and 12,000,000 shares of Series D Preferred Stock, $0.01 par value.

              The New Charter will also establish the Series D Preferred Stock
     with the preferences, limitations and relative rights as described under
     "DESCRIPTION OF IMS CAPITAL STOCK - Series D Preferred Stock."  Inasmuch
     as, pursuant to terms of the Merger, the Series C Preferred Stock will be
     converted into shares of common stock of IMS, references to the Series C
     Preferred Stock have been eliminated from the New Charter.

     VOTING RIGHTS

              Under the New Charter, following the Merger, holders of Series B
     Preferred Stock and Series D Preferred Stock will have no voting rights
     other than those voting rights required by the Colorado Business
     Corporation Act and other than, in the case of Series D Preferred Stock,
     rights to elect directors following certain failures in the payment of
     dividends and the redemption of the Series D Preferred Stock.  Prior to the
     Merger, holders of the Series B Preferred Stock have voting rights
     identical and equal to the voting rights of the Company Common Stock.

              In addition, the New Charter explicitly reduces the vote required
     for any matter that pursuant to the Colorado Corporation Code (as in effect
     immediately prior to July 1, 1994) required a two-thirds vote of all of the
     outstanding shares of the corporation entitled to vote or all of the
     outstanding shares of each class where class voting was required to only a
     majority of all the votes entitled to be cast on the matter by each voting
     group entitled to vote separately on the matter.

     LIQUIDATION RIGHTS

              Under the New Charter, following the Merger, the Series B
     Preferred Stock and the Series D Preferred Stock will be parity stock in
     respect of the rights to payments upon the liquidation, dissolution or
     winding-up of IMS.  Prior to the Merger, the rights of the holders of
     Series B Preferred Stock upon the liquidation, dissolution and winding-up
     of IMS are superior to similar rights for all other classes of IMS capital
     stock.

     CONVERSION RIGHTS

              The Articles of Incorporation of IMS prior to the Merger provide
     that the Series B Preferred Stock is convertible into Company Common Stock.
     However, they also provide that, upon a merger of IMS with another entity,
     the shares of Series B Preferred Stock shall, after such merger, be
     convertible into the kind and number of shares of stock or other securities
     or property to which such holder would have been entitled if, immediately
     prior to such merger, such holder had converted his shares of

                                       40

 
     Series B Preferred Stock into Company Common Stock.  Accordingly, following
     the Merger, shares of Series B Preferred Stock will be convertible into, at
     the holder's option, either $5.33 in cash, without interest, or two-thirds
     of a share of Series D Preferred Stock.

                        COMPARISON OF SHAREHOLDER RIGHTS

              The following is a summary of the material differences between the
     rights of IMS shareholders prior to the Merger and following the Merger.
     As IMS is the surviving corporation in the Merger with Subsidiary, the
     differences arise from the New Charter set forth in the Articles of Merger,
     to be effective upon consummation of the Merger (a copy of which is
     attached hereto as Appendix A to this Proxy Statement-Prospectus), as well
     as from the new By-Laws ("New By-Laws") to be adopted by IMS following the
     Merger.  This summary does not purport to be a complete statement of the
     rights of holders of Company Common Stock and Series B Preferred Stock
     following the Merger under, and is qualified in its entirety by reference
     to, Colorado law, as well as the Articles of Merger and the By-Laws in
     effect prior to and following the Merger.  For a description of the rights
     preferences, limitations and relative rights of the capital stock of IMS
     following the Merger, see "DESCRIPTION OF CAPITAL STOCK OF IMS."

     VOTING RIGHTS

              The New Charter explicitly reduces the vote required for any
     matter that pursuant to the Colorado Corporation Code (as in effect
     immediately prior to July 1, 1994) required a two-thirds vote of all of the
     outstanding shares of the corporation entitled to vote or all of the
     outstanding shares of each class where class voting was required to only a
     majority of all the votes entitled to be cast on the matter by each voting
     group entitled to vote separately on the matter.

     NOTICE OF SHAREHOLDER MEETINGS

              In the By-Laws of IMS in effect prior to the Merger, written
     notice of each meeting of the shareholders was required to be given to each
     shareholder of record not less than 10 nor more than 50 days before the
     date of the meeting.  The New By-Laws have changed the notice requirement
     to not less than 10 nor more than 60 days before the date of the meeting.
     In addition, the New By-Laws add a provision that at least 20 days notice
     be given if a sale, lease, exchange or other disposition of all or
     substantially all of the property and assets of the Company not in the
     usual and regular course of business is to be voted on.

     CONFLICTING INTEREST TRANSACTIONS

              The Colorado law and the New By-Laws contain provisions relating
     to certain conflicting interest transactions and the approval of such
     transactions by the Board of Directors.  The Board of Directors or a
     committee thereof cannot authorize a loan by the Company to a director of
     the Company or to an entity in which a director of the Company is a
     director or officer or has a financial interest, or a guaranty by the
     Company of an obligation of a director of the Company or of an obligation
     of an entity in which a director of the Company is a director or officer or
     has a financial interest, until at least 10 days after written notice of
     the proposed authorization of the loan or guaranty has been given to the
     shareholders who would be entitled to vote thereon if the issue of the loan
     or guaranty were submitted to a vote of shareholders.

     VOTE REQUIRED FOR EXTRAORDINARY MATTERS

              Generally, only the common stock is entitled to vote on matters
     submitted to a shareholder vote.  However, the New By-Laws provide that if
     a voting group is entitled to vote separately on a particular proposal,
     then such a proposal must be approved by a majority of all the votes
     entitled to be cast by such voting group.  Under Colorado law, holders of
     the shares of a particular class are entitled to vote

                                       41

 
     as a separate voting group on an amendment to the articles of incorporation
     or on a merger which (a) increases or decreases the aggregate number of
     authorized shares of that class, (b) effects an exchange or
     reclassification of all or part of the shares of the class into shares of
     another class, (c) effects an exchange or reclassification, or create the
     right of exchange, of all or part of the shares of another class into
     shares of the class, (d) changes the designation, preferences, limitations
     or relative rights of all or part of the shares of the class, (e) changes
     the shares of all or part of the class into a different number of shares of
     the same class, (f) creates a new class of shares having rights or
     preferences with respect to distributions or dissolutions that are prior,
     superior or substantially equal to the shares of the class, (g) increases
     the rights, preferences, or number of authorized shares of any class that,
     after giving effect to the amendment, have rights or preferences with
     respect to distributions or to dissolution that are prior, superior or
     substantially equal to the shares of the class, (h) limits or denies an
     existing preemptive right of all or a part of the shares of the class, and
     (i) cancels or otherwise affects rights to distributions or dividends that
     have accumulated but have not yet been declared on all or part of the
     shares of the class.

     INDEMNIFICATION

              The Articles of Incorporation in effect prior to the Merger state
     that the Company possesses and may exercise all powers of indemnification
     of directors, officers, employees, agents and other persons, and all powers
     and authority incidental thereto without regard to whether or not such
     powers and authority are provided for by Colorado law.  Although the New
     Charter does not provide for indemnification, the New By-Laws provide that
     the Company will indemnify any person who was, is or is threatened to be
     made a named defendant or respondent in a proceeding because the person is
     or was a director against specified liabilities incurred in, related to, or
     as a result of, the proceeding to the fullest extent permitted by law,
     including without limitation in circumstances in which, in the absence of a
     provision to the contrary in the by-laws, indemnification would be
     discretionary under the Colorado Business Corporation Act, if (a) the
     person conducted himself or herself in good faith; (b) the person
     reasonably believed:  (i) in the case of conduct in an official capacity
     with the Company, that his or her conduct was in the Company's best
     interests; and (ii) in all other cases, that his or her conduct was at
     least not opposed to the Company's best interests; and (c) in the case of
     any criminal proceeding, the person had no reasonable cause to believe his
     or her conduct was unlawful.

              In accordance with Colorado law, the New By-Laws provide that the
     Company will not indemnify a director under the provisions described above
     in connection with a proceeding by or in the right of the Company in which
     the director was adjudged liable to the Company or in connection with any
     other proceeding charging that the director derived an improper personal
     benefit, whether or not involving action in an official capacity, in which
     proceeding the director was adjudged liable on the basis that he or she
     derived an improper personal benefit.

              In addition to the foregoing, the New By-Laws provide that the
     Company will indemnify a person who was wholly successful, on the merits or
     otherwise, in the defense of any proceeding to which the person was a party
     because the person is or was a director, against reasonable expenses
     incurred by him or her in connection with the proceeding.

              In addition, the New By-Laws provide that the Company will
     indemnify an officer, employee, fiduciary or agent of the Company to the
     same extent as to a director.

     HOLDERS OF SERIES B PREFERRED STOCK

         Voting Rights

              Under the New Charter, following the Merger, holders of Series B
     Preferred Stock and Series D Preferred Stock will have no voting rights
     other than those voting rights required by the Colorado Business
     Corporation Act and other than, in the case of the Series D Preferred
     Stock, rights to elect

                                       42

 
     directors following certain failures in the payment of dividends and the
     redemption of the Series D Preferred Stock.  Prior to the Merger, holders
     of the Series B Preferred Stock have voting rights identical and equal to
     the voting rights of the Company Common Stock.

         Liquidation Rights

              Under the New Charter, following the Merger, the Series B
     Preferred Stock and the Series D Preferred Stock will be parity stock in
     respect of the rights to payments upon the liquidation, dissolution or
     winding-up of IMS.  Prior to the Merger, the rights of the holders of
     Series B Preferred Stock upon the liquidation, dissolution and winding-up
     of IMS are superior to similar rights for all other classes of IMS capital
     stock.

         Conversion Rights

              The Articles of Incorporation of IMS prior to the Merger provide
     that the Series B Preferred Stock is convertible into Company Common Stock.
     However, they also provide that, upon a merger of IMS with another entity,
     the shares of Series B Preferred Stock shall, after such merger, be
     convertible into the kind and number of shares of stock or other securities
     or property to which such holder would have been entitled if, immediately
     prior to such merger, such holder had converted his shares of Series B
     Preferred Stock into Company Common Stock.  Accordingly, following the
     Merger, shares of Series B Preferred Stock will be convertible into, at the
     holder's option, either $5.33 in cash, without interest, or two-thirds of a
     share of Series D Preferred Stock.

                      DESCRIPTION OF CAPITAL STOCK OF IMS

              The following are summaries of the terms of the capital stock of
     IMS following the consummation of the Merger, including the amendment to
     the Articles of Incorporation described in "AMENDMENT TO THE ARTICLES OF
     INCORPORATION OF IMS."  Such summaries are qualified in their entirety by
     reference to the provisions of the Articles of Incorporation of IMS to be
     in effect following the Merger, which can be found in the Articles of
     Merger, which is attached as Exhibit A to the Merger Agreement which is
     attached as Appendix A to this Proxy Statement-Prospectus.

     AUTHORIZED CAPITAL STOCK

              Following the Merger, the aggregate number of shares that IMS
     shall have authority to issue is 20,000,000 shares of common stock, without
     par value, 12,000,000 shares of Series D Preferred Stock, $0.01 par value,
     and 2,000,000 shares of Series B Preferred Stock, $1.00 par value.

     COMMON STOCK

              Following the Merger, each shareholder of record of common stock
     entitled to vote will have one vote for each share of such stock standing
     in his name on the books of the corporation, except that in the election of
     directors such holder will have the right to vote such number of shares for
     as many persons as there are directors to be elected.  Cumulative voting
     will not be allowed in the election of directors or for any other purpose.
     Pursuant to the Merger Agreement, immediately following the Merger, all the
     common stock of IMS will be held by Lilly.

                                       43

 
     SERIES D PREFERRED STOCK

         Rank

              Shares of Series D Preferred Stock will have a preference over
     shares of IMS's common stock upon liquidation, dissolution or winding-up of
     IMS.

         Dividends

              Holders of Series D Preferred Stock will be entitled to receive,
     if, as and when declared by the Board of Directors out of funds legally
     available therefor, cumulative cash dividends at an annual rate of $0.62
     per share, in preference to and in priority over any dividends with respect
     to the common stock of IMS.  Dividends will begin to accrue and be
     cumulative (regardless of whether such dividends have been declared by the
     Board of Directors) beginning on the date of issuance, and will be payable
     annually in arrears each December 31 until and unless redeemed by IMS.

         Voting Rights

              Outstanding shares of Series D Preferred Stock will have no voting
     rights other than voting rights required by the Colorado Business
     Corporation Act or as otherwise provided below.

              Whenever, at any time or times, dividends payable on any share or
     shares of Series D Preferred Stock are in arrears in an amount equal to at
     least two full annual dividends (whether or not declared and whether or not
     consecutive and whether or not funds are legally available for such
     dividends), the holders of record of the outstanding Series D Preferred
     Stock will have the exclusive right, voting separately as a single class,
     to elect one director of IMS at a special meeting of shareholders of IMS or
     at IMS's next annual meeting of shareholders, and at each subsequent annual
     meeting of shareholders.  At elections for such director, the holders of
     shares of Series D Preferred Stock will be entitled to cast one vote for
     each share held.

              Upon a failure by IMS to redeem any shares of Series D Preferred
     Stock pursuant to any demand duly made pursuant to a holder's redemption
     right discussed in "- Redemption - At the Option of Holders" below (whether
     or not such failure results from IMS's failure to have sufficient funds
     legally available for such redemption), then the holders of record of the
     Series D Preferred Stock will have, as their sole remedy in respect of such
     failure, the exclusive right, voting separately as a single class, to elect
     the smallest number of directors of IMS that will constitute a majority of
     the authorized number of members of the Board of Directors (including new
     directorships created) at a special meeting of shareholders of IMS or at
     IMS's next annual meeting of shareholders, and at each subsequent annual
     meeting of shareholders.  At elections for such directors, the holders of
     shares of Series D Preferred Stock will be entitled to cast one vote for
     each share held.  If such holders exercise such right to elect a majority
     of the directors, then following the election of such directors and during
     the period in which a majority of the directors are persons elected by such
     holders (or the successors of such directors), IMS will be required to
     redeem all of the shares of Series D Preferred Stock for which redemption
     was duly demanded as soon as practicable if and to the extent that funds
     are legally available therefor.

              Upon the vesting of a right of the holders of the Series D
     Preferred Stock to elect any directors, the maximum authorized number of
     members of the Board will be automatically increased, (i) in case of a
     right because of a failure to pay dividends, by one and, (ii) in the case
     of a right because of a failure to redeem, by the maximum number of members
     of the Board of Directors immediately up to that time authorized (but
     excluding from such maximum number the member, if any, authorized because
     of a failure to pay dividends), plus one, and the vacancy or vacancies so
     created will be filled by vote of the holders of the outstanding Series D
     Preferred Stock as set forth below.  A special meeting of the shareholders
     of IMS then entitled to vote will be called by the Chairman of the Board of
     Directors or the

                                       44

 
     President or the Secretary of IMS, if requested in writing by the holders
     of record of not less than 25% of the Series D Preferred Stock then
     outstanding.  At such special meeting, or, if such special meeting will not
     have been called, then at the next annual meeting of shareholders of IMS,
     the holders of the Series D Preferred Stock will elect, voting as above
     provided, a director or directors to fill such vacancy or vacancies created
     by the automatic increase in the number of members of the Board of
     Directors.  At any and all such meetings for such election, the holders of
     a majority of the outstanding shares of the Series D Preferred Stock will
     be necessary to constitute a quorum for such election, whether present in
     person or by proxy, and such director or directors will be elected by the
     vote of at least a plurality of shares held by such shareholders present or
     represented at the meeting.  Any director elected by holders of the Series
     D Preferred Stock pursuant to this Section may be removed at any annual or
     special meeting, by vote of a majority of the outstanding shares of the
     Series D Preferred Stock, with or without cause.  In case a director so
     elected will vacate such position, such vacancy may be filled by unanimous
     agreement of the remaining directors so elected, or their successors then
     in office, if any, or may be filled in the same manner as is provided above
     for the initial election of a director by the holders of the Series D
     Preferred Stock.

              The right of the holders of the Series D Preferred Stock, voting
     separately as a class, to elect one director of the Board because of a
     failure to pay dividends will continue until, and only until, such time as
     all arrears in dividends (whether or not declared) on the Series D
     Preferred Stock will have been paid or declared and set apart for payment,
     at which time such right will terminate, except as expressly provided by
     law, subject to revesting in the event of each and every subsequent failure
     of the character above-mentioned.  The right of such holders, voting
     separately as a class, to elect directors because of a failure to redeem
     will continue until, and only until, such time as IMS has redeemed all of
     the shares of Series D Preferred Stock for which redemption was duly
     demanded at which time such right will terminate, except as expressly
     provided by law.  Upon any termination of the right of the holders of the
     Series D Preferred Stock as a class to vote for a director or directors as
     herein provided, the term of office of any such director or directors then
     in office will terminate immediately.

         Redemption

              At the Option of Holders.  During the period of 30 days beginning
              ------------------------                                         
     on the fifth anniversary of the Effective Date, any one or more holders of
     shares of Series D Preferred Stock, at the option of such holders, may
     demand that IMS redeem any or all of their shares of Series D Preferred
     Stock at a redemption price of $8.00 per share, plus an amount equal to all
     accrued and unpaid dividends thereon (whether or not declared) to and
     including the date of redemption.  Such demand will be made by delivering
     to IMS at its principal executive offices a written demand during the 30-
     day period.  Such demand must specify the number of shares to be redeemed
     and will be irrevocable, except with the consent of IMS.  Following receipt
     of any such demand, IMS may, at its option, choose to redeem, or not to
     redeem, shares in accordance with such demand and the provisions described
     herein.  If shares are to  be so redeemed, IMS will fix a redemption date
     that will be not later than 90 days after such fifth anniversary.  IMS will
     give notice of redemption by first class mail, postage prepaid, mailed not
     less than 20 days prior to the date fixed for redemption to the holders
     whose shares are to be redeemed at their respective addresses appearing on
     the stock books of IMS.  Notice so mailed will be conclusively presumed to
     have been duly given whether or not actually received.  Such notice must
     state:  (i) the date fixed for redemption; (ii) the redemption price; (iii)
     the number of shares of Series D Preferred Stock to be redeemed and if less
     than all the shares held by such holder are to be redeemed, the number of
     shares to be so redeemed from such holder; (iv) the place where
     certificates for such shares are to be surrendered for payment of the
     redemption price; and (v) that after the close of business on such date
     fixed for redemption the shares to be so redeemed will not accrue
     dividends.  If IMS does not redeem all of the shares of Series D Preferred
     Stock for which redemption has been duly demanded, the sole remedy of the
     holders of such shares in respect of such failure to redeem will be the
     exercise of the voting rights described under "- Voting Rights" above.  For
     these purposes, IMS will be considered to have redeemed any shares for
     which redemption has been duly demanded if such shares are thereafter
     purchased by IMS or any person or entity that then owns, directly or
     indirectly, at least 50% of IMS's then outstanding common stock.

                                       45

 
              At the Option of IMS.  On and after the fifth anniversary of the
              --------------------                                            
     Effective Date, IMS, at its option, may redeem any or all shares of Series
     D Preferred Stock at a redemption price of $8.00 per share, plus an amount
     equal to all accrued and unpaid dividends thereon (whether or not declared)
     to and including the date of redemption.

              Redemption Procedures.  If IMS redeems less than all of the shares
              ---------------------                                             
     for which demands for redemption were duly made, or if less than all of the
     outstanding shares of Series D Preferred Stock are to be redeemed at the
     option of IMS, the shares to be redeemed will be selected pro rata (subject
     to rounding to avoid fractional shares) as nearly as practicable or by lot,
     or by such other method as IMS's Board may determine to be equitable;
     provided, however, that if IMS is proposing to redeem shares at its option
     --------  -------                                                         
     and any shares for which demands for redemption were duly made have not
     been redeemed, then priority will be given to the redemption of such shares
     for which such demands were duly made.

              Notice of any redemption at the option of IMS will be given by
     first class mail, postage prepaid, mailed not less than 30 nor more than 60
     days prior to the date fixed for redemption to the holders of record of the
     Series D Preferred Stock to be redeemed at their respective addresses
     appearing on the stock books of IMS.  The IMS Board will fix a record date
     for determining holders of record who are entitled to receive notice of any
     redemption, not more than 10 days prior to the mailing of such notice.
     Notice so mailed will be conclusively presumed to have been duly given
     whether or not actually received.  Such notice will state:  (i) the date
     fixed for redemption; (ii) the redemption price; (iii) the number of shares
     of Series D Preferred Stock to be redeemed and if less than all the shares
     held by such holder are to be redeemed, the number of shares to be so
     redeemed from such holder; (iv) the place where certificates for such
     shares are to be surrendered for payment of the redemption price; and (v)
     that after the close of business on such date fixed for redemption the
     shares to be so redeemed will not accrue dividends.

              Upon surrender in accordance with the notice of redemption, the
     certificate for any shares of Series D Preferred Stock so redeemed (duly
     endorsed or accompanied by appropriate instruments of transfer, if so
     required by IMS in such notice), the holders of record of such shares will
     be entitled to receive the redemption price, without interest.  In case
     fewer than all the shares represented by any such certificate are redeemed,
     a new certificate will be issued representing the unredeemed shares without
     cost to the holder thereof.

              Notice of redemption having been mailed as provided above, from
     and after the redemption date (unless default will be made by IMS in
     providing money for the payment of the redemption price) dividends on the
     shares of the Series D Preferred Stock called for redemption will cease to
     accrue, and said shares will no longer be deemed to be outstanding, and all
     rights of the holders thereof as shareholders of IMS (except the right to
     receive from IMS the redemption price) will cease.

         Preemptive Rights

              No holder of Series D Preferred Stock will, because of such
     holder's ownership of such stock, have a preemptive right to purchase,
     subscribe for or take any part of any capital stock of IMS nor will any
     such holder have a preemptive right to purchase, subscribe for or take any
     part of notes, debentures, bonds or any other securities of IMS, including,
     but not limited to, securities convertible into or carrying options or
     warrants to purchase capital stock of IMS.

         Liquidation Preference

              Upon any voluntary or involuntary liquidation, dissolution or
     winding-up of IMS, the holders of the Series D Preferred Stock will be
     entitled to receive out of the assets of IMS available for distribution to
     shareholders, before any distribution of assets is made to the holders of
     shares of common stock, an amount in cash equal to $8.00 per share, plus an
     amount equal to all accumulated and unpaid dividends on such shares of
     Series D Preferred Stock to and including the date of such liquidation,

                                       46

 
     dissolution or winding-up.  If, upon any voluntary or involuntary
     liquidation, dissolution or winding-up of IMS, the amounts payable with
     respect to the Series D Preferred Stock and any parity stock are not paid
     in full, the holders of the Series D Preferred Stock and such parity stock
     will share ratably in any such distribution of assets of IMS in proportion
     to the full respective preferential amounts (including accumulated and
     unpaid dividends) to which they are entitled.  After payment to the holders
     of the Series D Preferred Stock (including accumulated and unpaid
     dividends) described in this paragraph, the holders of Series D Preferred
     Stock will be entitled to no further participation in any distribution of
     assets of IMS.

         Conversion Rights

              Holders of the Series D Preferred Stock will have no rights to
     convert the Series D Preferred Stock into any other class of capital stock
     of IMS.

         Cancellation of Redeemed Shares

              All shares of Series D Preferred Stock redeemed as described in "-
     Redemption" above will be cancelled and will not be issuable by IMS.

         No Other Rights

              The shares of Series D Preferred Stock will not have any
     preferences, voting powers or relative, participating or other special
     rights except as set forth above and in the Articles of Incorporation or as
     otherwise required by applicable law.

     SERIES B PREFERRED STOCK

         Dividends

              The Series B Preferred Stock will earn cumulative dividends at a
     rate of 10% of the Liquidation Value (i.e., $.10 per share annually), which
     will be payable quarterly each September 30, December 31, March 31 and June
     30 until and unless converted as provided under "- Conversion" below.  All
     payments of dividends on the Series B Preferred Stock and the outstanding
     Series D Preferred Stock will be made in pari passu among the holders of
                                           -- ---- -----                     
     the Series D Preferred Stock and the holders of the Series B Preferred
     Stock and no holder of Series D Preferred Stock or holder of Series B
     Preferred Stock will be preferred over the other.  See "- Series D
     Preferred Stock" above.

         Voting Rights

              Outstanding shares of Series B Preferred Stock will have no voting
     rights other than such voting rights as will be required by the Colorado
     Business Corporation Act.

         Preemptive or Purchase Rights

              Holders of Series B Preferred Stock will not have preemptive
     rights to purchase, subscribe for or take any part of any capital stock of
     IMS nor will any such holders have preemptive rights to purchase, subscribe
     for or take any part of notes, debentures, bonds or any other securities of
     IMS, including, but not limited to, securities convertible into or carrying
     options or warrants to purchase capital stock of IMS.

                                       47

 
         Rights on Liquidation, Dissolution and Winding-up of IMS

              Upon any liquidation, dissolution or winding-up of IMS, the
     holders of the Series B Preferred Stock will be entitled to be paid, before
     any distribution or payment is made to the holders of the outstanding
     common stock, an amount in cash equal to $1.00 per share plus accrued and
     unpaid dividends (the "Series B Liquidation Value"), and the holders of the
     Series B Preferred Stock will not be entitled to any further or additional
     payment.  The Series B Preferred Stock and the Series D Preferred Stock
     will be parity stock in respect of rights to payment upon liquidation,
     dissolution or winding-up.

         Conversion

              The holders of the Series B Preferred Stock will have conversion
     rights as follows (the "Series B Conversion Rights"):

              Right to Convert.  Each share of Series B Preferred Stock will be
              ----------------                                                 
     convertible, at the option of the holder thereof, at any time, into either
     (i) the Series B Liquidation Value, payable in cash, of the Series B
     Preferred Stock on the date of conversion, without interest, or (ii) two-
     thirds of a share of the Series D Preferred Stock.

              Mechanics of Conversion.  Before any holders of Series B Preferred
              -----------------------                                           
     Stock will be entitled to convert their shares into cash or shares of
     Series D Preferred Stock, such holder must surrender the certificate or
     certificates therefor, duly endorsed, and must give written notice to IMS
     that such holder elects to convert the shares into cash or Series D
     Preferred Stock.  IMS will, as soon as practicable thereafter, either pay
     the required cash to the holder of Series B Preferred Stock or issue and
     deliver to such holder of Series B Preferred Stock a certificate or
     certificates for the number of shares of Series D Preferred Stock to which
     such holder will be entitled.  Such shares of Series D Preferred Stock will
     be subject to redemption by the Company as described above in "- Series D
     Preferred Stock - Redemption."

              Fractional Shares.  No fractional shares of Series D Preferred
              -----------------                                             
     Stock will be issued upon conversion of the Series B Preferred Stock.
     Fractional shares will not be issued; and, in lieu of fractional shares to
     which the holder would otherwise be entitled, IMS will pay cash equal to
     said fraction multiplied by 150% of the Series B Liquidation Value of a
     share of the Series B Preferred Stock.

              Changes in Series D Preferred Stock.  IMS will not issue any
              -----------------------------------                         
     shares of Series D Preferred Stock other than those shares issued in
     connection with the Merger or any shares subsequently issued upon
     conversion of Series B Preferred Stock as provided above or upon exercise
     of the Company Options and the Company Warrants contemplated by the
     Articles of Merger.

              The number of shares of Series D Preferred Stock outstanding at
     any time after the Effective Date may not be increased by a stock dividend
     payable in shares of Series D Preferred Stock or by a subdivision or split-
     up of shares of Series D Preferred Stock.

              The number of shares of Series D Preferred Stock outstanding at
     any time after the Effective Date may not be decreased by a combination of
     the outstanding shares of Series D Preferred Stock.

              If at any time after the Effective Date there occurs any capital
     reorganization, or any reclassification of the capital stock of IMS (other
     than a change in par value or as a result of a stock dividend or
     subdivision, split-up or combination of shares), or the consolidation or
     merger of IMS with or into another person (other than a consolidation or
     merger in which IMS is the continuing entity and which does not result in
     any change in the Series D Preferred Stock), or the sale or other
     disposition of all or substantially all of the properties and assets of IMS
     as an entity to any other person, the shares of Series B Preferred Stock
     will, after such reorganization, reclassification, consolidation, merger,
     sale or other

                                       48

 
     disposition, be convertible into the kind and number of shares of stock or
     other securities or property of IMS or of the entity resulting from such
     consolidation or surviving such merger or to which such properties and
     assets will have been sold or otherwise disposed to which such holder would
     have been entitled if, immediately prior to such reorganization,
     reclassification, consolidation, merger, sale or other disposition, such
     holder had converted his shares of Series B Preferred Stock into Series D
     Preferred Stock.  The provisions of this paragraph similarly apply to
     successive reorganizations, reclassifications, consolidations, mergers,
     sales or other dispositions.

         Notices of Record Date

              In the event of any taking by IMS of a record of the holders of
     any class of securities for the purpose of determining the holders thereof
     who are entitled to receive any dividend (other than a cash dividend) or
     other distribution, IMS will mail to each holder of Series B Preferred
     Stock, at least 20 days prior to the specified date, a notice specifying
     the date on which any such record is to be taken for the purpose of such
     dividend or distribution.

         Reservation of Stock Issuable Upon Conversion

              IMS will at all times reserve and keep available out of its
     authorized but unissued shares of Series D Preferred Stock solely for the
     purpose of effecting the conversion of the shares of Series B Preferred
     Stock such number of its shares of Series D Preferred Stock as will from
     time to time be sufficient to effect the conversion of all outstanding
     shares of the Series B Preferred Stock.

         Protective Provisions

              For as long as any of the Series B Preferred Stock is outstanding,
     IMS will not, without first obtaining the approval (by vote or written
     consent, as provided by law) of the holders of at least 51% of the
     outstanding shares of Series B Preferred Stock, alter or change the rights,
     preferences or privileges of the Series B Preferred Stock.

         No Reissuance of Preferred Stock

              No share or shares of Series B Preferred Stock acquired by IMS by
     reason of redemption, purchase, conversion or otherwise will be reissued,
     and all such shares will be cancelled, retired and eliminated from the
     shares that IMS will be authorized to issue.

         Amendment and Waiver

              Amendments, modifications or waivers of any of the above terms of
     the Series B Preferred Stock will be binding and effective if the prior
     written consent of holders of at least 51% of the Series B Preferred Stock
     outstanding at the time such action is taken is obtained; provided that no
     such action will change (a) the rate at which or the manner in which
     dividends on the Series B Preferred Stock accrue or the times at which such
     dividends become payable, unless the prior written consent of the holders
     of at least 91% of the Series B Preferred Stock then outstanding is
     obtained, (b) the Series B Conversion Rights or the number of shares or
     class of stock into which the Series B Preferred Stock is convertible,
     unless the prior written consent of the holders of at least 91% of the
     Series B Preferred Stock then outstanding is obtained or (c) the percentage
     required to approve any change described in clauses (a) and (b) above,
     unless the prior written consent of the holders of at least 91% of the
     Series B Preferred Stock then outstanding is obtained.

             CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

              The following discussion is a summary of the principal federal
     income tax consequences of the Merger to holders of IMS  stock, warrants
     and options.  The discussion is applicable to persons who hold their stock
     (or warrants) as capital assets and to persons who received their options
     in consideration for personal services rendered to IMS.  The discussion
     assumes that the IMS stock is not, and the Series D Preferred Stock will
     not be, traded on an established securities market or an over-the-counter
     market or quoted in an interdealer quotation system.  The discussion is
     based on laws, regulations, rulings and decisions currently in effect, all
     of which are subject to change (which change could apply retroactively).
     Certain of the consequences described below are based on provisions of the
     Code that have not yet been the subject of final regulations or other
     definitive guidance by the Internal Revenue Service.  The discussion does
     not take account of rules that are applicable to persons that are subject
     to special treatment under the Code, including without limitation, foreign
     persons.  The discussion also does not address state, local or foreign tax
     consequences of the Merger.  No rulings have been or will be requested from
     the Internal Revenue Service with respect to the tax consequences of the
     Merger.  Each holder of IMS stock should consult his or her own tax advisor
     as to the specific tax consequences of the Merger to that holder.

              Receipt of Cash.  A holder of Company Common Stock or Series B
     Preferred Stock (or Company Warrants) who elects to receive cash in
     exchange for all or a portion of his or her IMS stock (or Company Warrants)
     will recognize taxable gain or loss for federal income tax purposes with
     respect to those shares (or Company Warrants) in an amount equal to the
     difference between (a) the amount of the cash received by such holder and
     (b) the holder's adjusted tax basis in the shares of IMS stock (or Company
     Warrants) surrendered in exchange therefor.  Such gain or loss will be
     long-term capital gain or loss if such IMS stock (or Company Warrants) are
     considered to have been held for more than one year.

              Receipt of Series D Preferred Stock Without Entering Into Put/Call
     Agreement.  The exchange of all or a portion of a holder's Company Common
     Stock or Series B Preferred Stock for Series D Preferred Stock by a holder
     who elects not to have such stock subject to a Put/Call Agreement should be
     treated as part of a tax-free reorganization under Section 368(a)(1)(E) of
     the Code.  Accordingly, such holder should not recognize taxable gain or
     loss for federal income tax purposes with respect to those shares of IMS
     stock exchanged for Series D Preferred Stock, and the aggregate tax basis
     of the Series D Preferred Stock received in the exchange should be equal to
     the basis of the IMS stock exchanged therefor.

              Receipt of Series D Preferred Stock Subject to Put/Call Agreement.
     The federal income tax treatment of the exchange of all or a portion of a
     holder's IMS stock for Series D Preferred Stock by a holder who elects to
     have such stock subject to a Put/Call Agreement is uncertain.  The
     transaction could be treated generally as a nontaxable exchange of stock
     for stock pursuant to a tax-free reorganization of IMS, or it could be
     treated as a taxable exchange of IMS stock for a deferred payment
     obligation issued by Lilly.  Based on the relevant facts and circumstances,
     however, the better view is that the transaction should be treated
     generally as a nontaxable exchange of stock for stock pursuant to a
     reorganization described in Section 368(a)(1)(E) of the Code. Consistent
     with that view, Lilly and IMS intend to treat the transaction in accordance
     with its form and the Series D Preferred Stock that is subject to a
     Put/Call Agreement as constituting stock of IMS that is owned by the holder
     of the Series D Preferred Stock, and neither Lilly nor IMS will claim an
     interest deduction with respect thereto.  (The tax consequences of the
     possible treatment as a taxable deferred payment sale are described below
     under "Alternative Characterization".)  In addition, while the
     characterization of the put and call rights with Lilly under the Put/Call
     Agreement is not free from doubt, they should be viewed as a property right
     that is separate from the Series D Preferred Stock.

              If the transaction is treated generally as a nontaxable exchange,
     the consequences to such a holder should be similar to those described
     under "Receipt of Series D Preferred Stock Without Entering Into Put/Call
     Agreement" above, except that such a holder should recognize taxable gain
     (but possibly not loss) for federal income tax purposes in respect of the
     net fair market value (if any) to the holder of the put and call rights
     with Lilly.  Any such gain or loss should be long-term capital gain or loss
     if such IMS stock

                                       50

 
     is considered to have been held for more than one year.  The aggregate tax
     basis of the Series D Preferred Stock received in the exchange should
     generally be equal to the basis of the IMS stock exchanged therefor,
     subject to possible adjustment in respect of the put and call rights with
     Lilly.  The holder's tax basis in the put rights should be equal to their
     fair market value.

              Holders of IMS stock who receive Series D Preferred Stock that is
     subject to a Put/Call Agreement will be treated for federal income tax
     purposes as entering into a "conversion transaction" as defined in Section
     1258(c) of the Code.  As a result, in the absence of regulations or other
     guidance to the contrary, any amount that otherwise would be treated as
     capital gain arising from the disposition of the Series D Preferred Stock
     (or from the expiration or termination of the call options with Lilly) will
     be treated instead as ordinary income to the extent that the gain does not
     exceed the amount of interest income that would have accrued on the
     holder's net investment in the conversion transaction.  For this purpose,
     the net investment is equal to the fair market value of the Series D
     Preferred Stock plus the net fair market value of the put and call rights
     (if any) at the time of the Merger, and the interest on such net investment
     is computed by utilizing a rate equal to 120 percent of the applicable
     Federal rate (which is based on prevailing market interest rates on U.S.
     Government debt instruments having a maturity comparable to that of the
     conversion transaction).  Under regulations that have not yet been issued,
     the amount of gain that is recharacterized as ordinary income should be
     reduced to reflect ordinary income received in respect of the conversion
     transaction, including dividend income.

              Discount Preferred Stock.  If and to the extent that the fair
     market value of the Series D Preferred Stock received in the Merger (as
     determined without taking account of any put and call options with Lilly)
     is less than $8.00 per share (i.e., the Series D Preferred Stock's
                                   ----                                
     redemption price at maturity), the Series D Preferred Stock will have an
     issue price that is less than its redemption price at maturity.  Under
     Section 305(c) of the Code, in general (subject to regulations that have
     not yet been issued in final form), a holder of such stock will be deemed
     to receive distributions from IMS, equal in the aggregate to the difference
     between the issue price and the redemption price at maturity of such Series
     D Preferred Stock, on a constant yield basis over the life of the Series D
     Preferred Stock.  Such a deemed distribution will be taxable to a holder of
     the Series D Preferred Stock as ordinary dividend income to the extent of
     the current and accumulated earnings and profits of IMS in the year of the
     deemed distribution.  A holder's adjusted tax basis in the Series D
     Preferred Stock will be increased by the amount of such dividend income
     recognized by the holder.  To the extent that the amount of the deemed
     distributions is greater than the current and accumulated earnings and
     profits of IMS, the deemed distributions will be treated as a non-taxable
     return of capital (to the extent of the holder's basis in the Series D
     Preferred Stock) and there should be no net effect on a holder's tax basis
     in those shares as a result of such deemed distributions.  If and to the
     extent such deemed distributions exceed the holder's tax basis in the
     Series D Preferred Stock, they will be treated as taxable gain.

              Alternative Characterization.  The Internal Revenue Service may
     take the position that the exchange of IMS stock for Series D Preferred
     Stock by a holder who elects to have such stock subject to a Put/Call
     Agreement should be treated as a taxable purchase of IMS stock by Lilly in
     exchange for its deferred payment obligation rather than as a nontaxable
     exchange pursuant to a tax-free reorganization.  In that case, a holder of
     IMS stock will recognize taxable gain or loss equal to the difference
     between (a) the amount realized (in general, $8.00 per share of Series D
     Preferred Stock) and (b) the holder's adjusted tax basis in the shares of
     IMS stock exchanged therefor.  Such gain or loss will be long-term capital
     gain or loss if such IMS stock is considered to have been held for more
     than one year.

              Under the foregoing characterization, unless a holder elects to
     recognize gain in the taxable year of the Merger, the exchange of IMS stock
     for a deferred payment obligation (i.e., the Series D Preferred Stock
                                        ----                              
     subject to the Put/Call Agreement) issued by Lilly should be eligible for
     installment sale treatment under Section 453 of the Code.  In general, such
     installment sale gain would be recognized proportionally as proceeds are
     received by the holder upon a redemption or other disposition of the
     deferred payment obligation or upon a pledge of the deferred payment
     obligation to secure a loan. Under Section 453A

                                       51

 
     of the Code, a holder who reports such gain on the installment method
     generally would be required to pay to the Internal Revenue Service interest
     on the deferred tax liability if the sales price of the IMS stock by such
     holder exceeds $150,000 and the face amount of all installment obligations
     held by the taxpayer which arose during, and are outstanding as of the
     close of, the taxable year exceeds $5 million.

              Election to Retain Series B Preferred Stock.  A holder of Series B
     Preferred Stock who elects to retain such stock will not recognize any
     taxable gain or loss in respect of such stock at the time of the Merger.
     Upon a subsequent redemption of such stock for cash or a conversion of such
     stock into Series D Preferred Stock, the tax consequences to the holder
     generally will be as described under "Receipt of Cash", "Receipt of Series
     D Preferred Stock Without Entering Into Put/Call Agreement", "Receipt of
     Preferred Stock Subject to Put/Call Agreement" and "Accrued Dividend on
     Series B Preferred", as the case may be, except that (x) payments in
     respect of accrued dividends will be taxable as ordinary dividend income to
     the extent of the current and accumulated earnings and profits of IMS for
     the taxable year and (y) in the case of a conversion of the Series B
     Preferred Stock into Series D Preferred Stock, the risk that such
     conversion will be treated as described in "Alternative Characterization"
     is probably greater than the risk of such treatment to a holder who
     acquires such stock at the time of the Merger.

              Accrued Dividend on Series B Preferred.  IMS believes that it
     will have no accumulated or current earnings and profits for the taxable
     year in which the Merger takes place.  Accordingly, any accrued dividend
     on the Series B Preferred Stock that is paid at the time of the Merger
     should be treated as a non-taxable return of capital that reduces the
     holder's tax basis in the Series B Preferred Stock (to the extent thereof)
     and, to the extent such accrued dividend exceeds such tax basis, it will be
     treated as taxable gain.  Such gain will be long-term capital gain if the
     Series B Preferred Stock is considered to have been held for more than one
     year.

              Cash in Lieu of Fractional Shares.  In the event that a holder of
     IMS stock receives, in the Merger, cash in lieu of a fractional share of
     IMS stock, such holder will recognize taxable gain or loss in an amount
     equal to the difference between (a) the amount of such cash and (b) the
     portion of the holder's adjusted tax basis in the IMS stock that is
     allocable to such fractional share.  Such gain loss will be long-term
     capital gain or loss if such IMS stock is considered to have been held for
     more than one year.

              Exercise of Warrants.  A holder of Company Warrants who exercises
     his or her warrants so as to receive (or be deemed to receive) Company
     Common Stock and elects to receive Series D Preferred Stock pursuant to the
     Merger generally should be subject to the same federal income tax
     consequences as described above, except that (i) the holder's initial tax
     basis in the Company Common Stock received (or deemed to be received) upon
     exercise of the warrants generally will equal the exercise price plus the
     holder's tax basis in the warrants, and (ii) the holder's holding period in
     the Company Common Stock will begin on the exercise date of the warrants.

              Exchange of Warrants.  A holder of Company Warrants who elects to
     exchange all or a portion of his or her warrants for warrants in respect of
     Series D Preferred Stock should recognize taxable gain or loss for federal
     income tax purposes in an amount equal to the difference between (a) the
     fair market value of the warrants in respect of Series D Preferred Stock
     received by such holder and (b) the adjusted basis of the Company Warrants
     surrendered in exchange therefor.  Such gain or loss will be long-term
     capital gain or loss if the Company Warrants are considered to have been
     held for more than one year.  The holding period of warrants in respect of
     Series D Preferred Stock received in the exchange will begin the day after
     the exchange.

              Treatment of Series D Preferred Stock.  Assuming the Series D
     Preferred Stock is respected as stock of IMS for federal income tax
     purposes (see "Receipt of Series D Preferred Stock Subject to Put/Call
     Agreement" and "Alternative Characterization" above), distributions in
     respect of such stock will be taxable as ordinary dividend income to the
     extent of the current and accumulated earnings and profits of IMS for the
     taxable year.  To the extent that the amount of such distributions is
     greater than the current

                                       52

 
     and accumulated earnings and profits of IMS, the distributions will be
     treated as a non-taxable return of capital that reduces the holder's tax
     basis in such stock (to the extent thereof), and to the extent the
     distributions exceed such tax basis they will be treated as taxable gain.
     See also "Discount Preferred Stock" above.  In general, a corporate holder
     of Series D Preferred Stock that is subject to a Put/Call Agreement will
     not be eligible for the dividends received deduction.

              Subject to the preceding discussion (including the discussion of
     conversion transactions under Section 1258 of the Code), gain or loss on
     the sale, exchange, or redemption of the Series D Preferred Stock generally
     will be capital gain or loss.  Such gain or loss will be long-term capital
     gain or loss if the Series D Preferred Stock is considered to have been
     held for more than one year.  The holding period of the Series D Preferred
     Stock received by a holder of Company Common Stock or Series B Preferred
     Stock generally will include the period during which the shares of Company
     Common Stock or Series B Preferred Stock, respectively, surrendered in
     exchange therefor were held, assuming the exchange is treated as part of a
     tax-free reorganization under Section 368(a)(1)(E) of the Code.  See
     "Exercise of Warrants" above for a discussion of the holding period of a
     holder of warrants who receives stock upon the exercise of those warrants.

              Treatment of Stock Options -- Cash Out of Option.  Each holder of
     a Company Option who received the option in connection with his or her
     performance of personal services for IMS (an "Optionee") and who elects to
     receive cash in exchange for the option will be required to recognize
     compensation taxable as ordinary income for federal income tax purposes in
     an amount equal to the amount of cash received.

              --  Conversion to Lilly Option.  An Optionee who elects to have
     his or her Company Option converted into a Lilly Option should not be
     required to recognize income for federal income tax purposes as a result of
     such conversion.  Rather, the Optionee will generally be required to
     recognize compensation taxable as ordinary income for federal income tax
     purposes at the time of the exercise of the Lilly Option.

              --  Conversion to Option to Purchase Series D Preferred Stock
     Without Entering Into Put/Call Agreement.  An Optionee who elects to have
     his or her Company Option converted into an option to purchase Series D
     Preferred Stock and who elects not to have the Put/Call Agreement apply to
     such stock should not be required to recognize income for federal income
     tax purposes with respect to the converted option prior to the exercise of
     the option.  At the time of the exercise of the option, the Optionee would
     be required to recognize compensation taxable as ordinary income for
     federal income tax purposes equal to the excess of the fair market value of
     such stock at the time of exercise over the exercise price of the option
     and the Optionee will have a basis in the stock equal to the sum of the
     exercise price plus the amount of income required to be recognized.  The
     Optionee's holding period in the stock will begin on the exercise date of
     the option.  See "Discount Preferred Stock" and "Treatment of Series D
     Preferred Stock" above with respect to the treatment of Series D Preferred
     Stock received by an Optionee pursuant to the exercise of an option.  In
     the event that an option is redeemed for cash, the Optionee will be
     required to recognize compensation taxable as ordinary income in an amount
     equal to the amount of cash received upon redemption.

              --  Conversion to Option to Purchase Series D Preferred Stock With
     Put/Call Agreement.  Although the federal income tax consequences from such
     conversion are not free from doubt, an Optionee who elects to have his or
     her Company Option converted into an option to purchase Series D Preferred
     Stock and who elects to have the Put/Call Agreement apply to such stock
     probably would not be required to recognize income for federal income tax
     purposes with respect to the converted option prior to the exercise of the
     option.  At the time of the exercise of the option, the Optionee would be
     required to recognize compensation taxable as ordinary income for federal
     income tax purposes equal to the excess of the fair market value of such
     stock at the time of exercise over the exercise price of the option and the
     Optionee will have a basis in the stock equal to the sum of the exercise
     price plus the amount of income

                                       53

 
     required to be recognized.  The Optionee's holding period in the stock will
     begin on the exercise date of the option.  See "Discount Preferred Stock"
     and "Treatment of Series D Preferred Stock" above with respect to the
     treatment of Series D Preferred Stock received by an Optionee pursuant to
     the exercise of an option.  In the event that an option is redeemed for
     cash, the Optionee will be required to recognize compensation taxable as
     ordinary income in an amount equal to the amount of cash received upon
     redemption.

              It is possible that an Optionee who elects to have his or her
     option converted into an option to purchase Series D Preferred Stock and
     who elects to have a Put/Call Agreement apply to such stock would be
     required to recognize income for federal income tax purposes at the time
     that the Optionee's 12-month or 30-month put rights become exercisable.  If
     the alternative treatment described in this paragraph applies, the Optionee
     would be required to recognize compensation taxable as ordinary income for
     federal income tax purposes at the time that the applicable put right
     becomes exercisable in an amount equal to the excess, if any, of (i) the
     amount that could be received by the Optionee if the Optionee put the stock
     to Lilly at such time over (ii) the sum of the exercise price of the Option
     and, with respect to the 30-month put right, any amount previously
     recognized by the Optionee as compensation with respect to the option.  The
     Optionee would also be required to recognize compensation taxable as
     ordinary income at the time that he or she exercises the option equal to
     the excess, if any, of (i) the fair market value at the time of exercise of
     the stock subject to the option over (ii) the sum of the exercise price of
     the option and any amount previously recognized by the Optionee as
     compensation with respect to the option.  If, at the time that the option
     is exercised, the excess of the fair market value of the stock subject
     thereto over the exercise price thereof is less than the amount of income
     previously recognized by the Optionee with respect to the option, the
     Optionee would not be entitled to a deduction for federal income tax
     purposes with respect to such difference, but may be entitled to take a
     capital loss with respect thereto, although the ability to take such loss
     is not free from doubt.

              --  Federal Employment Tax.  In general, any amount required to be
     recognized as compensation taxable as ordinary income with respect to an
     option will also be treated as wages for purposes of the health insurance
     portion of FICA withholding taxes, and for other federal employment tax
     purposes.

                       RIGHTS OF DISSENTING SHAREHOLDERS

              Pursuant to the terms of the Merger Agreement, if holders of
     capital stock of IMS have exercised dissenters' rights in connection with
     the Merger in accordance with the provisions of Article 113 of the Colorado
     Business Corporation Act ("Article 113"), any Dissenting Shares (as defined
     below) will not be converted into the Merger Consideration but will be
     converted into the right to receive such consideration as may be determined
     to be due with respect to such Dissenting Shares pursuant to the laws of
     the State of Colorado.

              The following summary of the provisions of Article 113 is not
     intended to be a complete statement of such provisions and is qualified in
     its entirety by reference to the full text of Article 113, a copy of which
     is attached to this Proxy Statement-Prospectus as Appendix D and is
     incorporated herein by reference.

              If the Merger is approved by the required vote of IMS's
     shareholders and is not abandoned or terminated, each holder of shares of
     Company Common Stock or Series B Preferred Stock who does not vote in favor
     of the Merger and who follows the procedures set forth in Article 113 will
     be entitled to have his shares of Company Common Stock or Series B
     Preferred Stock purchased by IMS for cash at their Fair Value (as defined
     below).  The "Fair Value" of shares of Company Common Stock or Series B
     Preferred Stock will be determined as of the day before the first
     announcement of the terms of the proposed Merger, excluding any
     appreciation or depreciation in anticipation of the proposed Merger, except
     to the extent that exclusion would be inequitable.  The shares of Company
     Common Stock or Series B Preferred Stock with respect to which holders have
     perfected their purchase demand in accordance with Article 113 and have not
     effectively withdrawn or lost such rights are referred to in this Proxy
     Statement-Prospectus as the "Dissenting Shares."

              Prior to the vote taken to approve the proposed Merger at the
     Special Meeting, a shareholder who wishes to assert dissenters' rights must
     (a) deliver written notice to IMS of his intent to demand payment for
     shares if the proposed Merger is approved and (b) not vote any of his
     shares in favor of the proposed Merger.  Within 10 days after approval of
     the Merger by IMS's shareholders, IMS must mail a notice of such approval
     (the "Approval Notice") to all shareholders who are entitled to demand
     payment for their shares under Article 113, together with a copy of Article
     113 and a form for demanding payment.  If a shareholder's shares are held
     of record by a third party (for example, a broker), the record holder must
     either assert the dissenters' rights or must consent to the beneficial
     owner's assertion of dissenters' rights.

              A shareholder of IMS electing to exercise dissenters' rights must,
     within 30 days after the date on which the Approval Notice is mailed to
     such shareholder, demand in writing from IMS the purchase of his or her
     shares of Company capital stock and payment to the shareholder of their
     Fair Value and must submit the certificate(s) representing the Dissenting
     Shares to IMS in accordance with the terms of the Approval Notice.  A
     shareholder who does not demand payment and deposit share certificates as
     required by the date set in the Approval Notice is not entitled to payment
     for shares under Article 113.  A holder who elects to exercise dissenters'
     rights should mail or deliver his or her written demand for payment to IMS
     at its principal offices directed to the attention of James A. Larson,
     Secretary.  The demand should specify the holder's name and mailing
     address, the number of shares of Company Common Stock or Series B Preferred
     Stock owned by such shareholder and state that such holder is demanding
     purchase of his or her shares in payment of their Fair Value.  Upon the
     later of the Effective Time and receipt by IMS of each payment demand made
     pursuant to Article 113, IMS must pay the amount IMS estimates to be the
     Fair Value of the Dissenting Shares, plus interest at the rate of interest
     then paid by IMS on its principal bank loans, to each dissenter who has
     complied with the requirements of Article 113 and who has not yet received
     payment, together with certain financial information of IMS, an explanation
     of how interest was calculated and a copy of Article 113.

                                       55

 
              Any holder of Dissenting Shares who has not accepted an offer made
     by IMS may, within 30 days after IMS first offered payment for his or her
     shares, notify IMS in writing of his or her own estimate of the Fair Value
     of his or her shares and demand payment of the estimated amount, plus
     interest, less any payment made under Article 113, if (i) the holder of
     Dissenting Shares believes that the amount offered or paid by IMS under
     Article 113 is less than the Fair Value of the shares, or that the interest
     due was incorrectly calculated, (ii) IMS fails to make payment within 60
     days after the date set by IMS as the date by which it must receive the
     payment demand, or (iii) IMS, having failed to consummate the proposed
     Merger, does not return share certificates deposited by a holder as
     required by Article 113.  If IMS and the shareholder fail to agree upon the
     Fair Value of the shares, then within 60 days after receiving the payment
     demand IMS must petition the District Court of Jefferson County (the
     "Court") to determine the Fair Value of such holder's shares of Company
     capital stock.  If IMS does not commence the proceeding within the 60-day
     period, it must pay each holder of Dissenting Shares whose demand remains
     unresolved the amount demanded.  IMS must make all holders of Dissenting
     Shares whose demands remain unresolved parties to the proceeding as an
     action against their shares.  The Court may appoint one or more persons as
     appraisers to receive evidence and recommend a decision on the question of
     Fair Value.  Each holder of Dissenting Shares made a party to the
     proceeding is entitled to judgment for the amount, if any, by which the
     Court finds that the Fair Value of his or her shares, plus interest,
     exceeds the amount paid by IMS.

              If any holder of shares of Company Common Stock or Series B
     Preferred Stock who demands the purchase of his or her shares under Article
     113 fails to perfect, or effectively withdraws or loses his or her right
     to, such purchase, the shares of such holder will be converted into the
     right to receive the Merger Consideration, in the case of the Company
     Common Stock, or be deemed to have made an Election to Retain Series B
     Preferred Stock in the case of the Series B Preferred Stock, each in
     accordance with the Merger Agreement.

                 SELECTED CONSOLIDATED FINANCIAL DATA OF LILLY
             (IN MILLIONS, EXCEPT OTHER DATA AND PER SHARE AMOUNTS)

              The following selected consolidated financial data for the five
     years ended December 31, 1994 are derived from consolidated financial
     statements of Lilly which have been audited by Ernst & Young LLP,
     independent auditors. The financial data for the six months ended June 30,
     1995 and June 30, 1994 are derived from unaudited consolidated financial
     statements. The consolidated financial data for the six-month periods ended
     June 30, 1995 and June 30, 1994 include all adjustments, consisting of
     normal recurring accruals, which Lilly considers necessary for a fair
     presentation of the consolidated financial position and consolidated
     results of operations for these periods. Operating results for the six
     months ended June 30, 1995 are not necessarily indicative of the results
     that may be expected for the entire year ending December 31, 1995. The
     following data should be read in conjunction with the information
     concerning Lilly incorporated by reference in this Proxy Statement-

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                     OF IMS

         OVERVIEW

              The Company develops and operates computer based communication
     networks that automate routine and specialized text, voice, data and image
     exchanges from hospitals, managed care organizations, clinical
     laboratories, pharmaceutical companies, pharmacy chains and other
     healthcare providers to physicians. The networks, generally referred to as
     IMS MEDACOM/(R)/ Networks, enable such healthcare entities ("sponsors") to
     be linked with participating physician offices and physicians to be linked
     to each other to facilitate the exchange of clinical, financial and
     administrative information related to the delivery of healthcare services.

              Sponsors pay various fees to utilize an IMS MEDACOM/(R)/ Network
     to communicate with selected physicians or other network users in a given
     market on a single network (a "local" sponsor) or on several networks (a
     "national" sponsor). Physicians are not charged fees to participate on a
     network for basic network communication services and generally are
     designated for participation on a network, with the approval of the
     physician, by a sponsor seeking to improve communication with certain
     physicians. Generally, licenses to physicians for the proprietary IMS
     software installed at the physician practice sites on devices owned by
     physicians are directly maintained with IMS.

              IMS markets its software and networks under three general
     arrangements.

           Large Markets

              In 26 of the largest 50 metropolitan markets in the United States,
     the Company operates, directly or under a contract with a local network
     partner, IMS MEDACOM/(R)/ Networks in which all healthcare providers,
     suppliers, payors and others in the market have an opportunity to utilize
     the network for various aspects of medical communication needs. The "open
     architecture" networks may be utilized by any sponsor which intends to
     communicate with physicians or other sponsors in the market area under a
     "network services agreement" ("NSA"). Under an NSA, local sponsors contract
     with IMS or the network, for implementation of an individualized automated
     communications plan utilizing the network for an annual fee determined by
     either (a) the size of the sponsoring institution and scope of the network
     design, or (b) the volume and characteristics of communications with
     designated physician sites or other external sites (pharmacies, clinics,
     ancillary treatment services, etc.). In addition to annual sponsor fees,
     IMS may receive implementation fees, as well as incremental development and
     deployment fees for custom software interfaces or workstation applications
     as requested by the sponsor. The typical term for an NSA is five years,
     though shorter participation commitments are available under significantly
     higher fee structures. Most NSAs include general renewal upon expiration at
     increased or renegotiated fees. NSA revenue is recognized as earned monthly
     by prorating the fixed annual fee while certain custom development or
     implementation fees are recognized upon project completion.

              The Company intends to aggressively pursue the development of open
     architecture IMS MEDACOM/(R)/ Networks in at least the 50 largest
     metropolitan markets, measured by the number of practicing physicians in
     the market.

           Smaller Market Networks

              In selected smaller markets (typically those with less than 1,500
     practicing physicians), a local healthcare service provider or management
     entity contracts with IMS to receive a license of IMS technology and to
     implement a network under a network license agreement ("NLA"). Under an
     NLA, the licensee generally receives a nonexclusive license to use the IMS
     proprietary software for a fixed period, generally a five year term with
     annual renewals thereafter. The licensee can operate a network on its own
     or retain

                                       60

 
     IMS to manage the network. All physician site licenses under an NLA are
     with the Company so the Company retains the right in most cases to permit
     other local sponsors or licensees or national sponsors to communicate with
     the NLA physicians. At the Company's option, the NLA licensee receives a
     negotiated portion of local and national sponsorship fees in the
     nonexclusive territory to implement the network service.

              Typically, NLA licensees pay fees at approximately 50% of the
     corresponding aggregate five-year fees under an NSA, and include a defined
     obligation for the NLA licensee to staff, operate, market and support the
     local network and attain physician participation.

              The NLA license fee is recognized as revenue in the year in which
     the NLA licensee receives the installation of the network software. Any
     technology support and maintenance fees associated with the NLA are
     recognized on a prorated monthly basis. In addition, the Company may
     receive implementation fees that are recognized as earned. Other NLA
     revenue sources include optional monthly management services fees for
     services provided by the Company, generally at the election of the NLA
     licensee, to provide network oversight and operation, and custom
     development or new services implementation fees that are recognized upon
     project completion.

           Certain National Sponsors

              National network sponsors enter into national sponsor agreements
     ("NSPA") pursuant to which the licensee is afforded the right to
     communicate with designated physicians or other users in various networks.
     Typically, the NSPA provides fees determined as an annual charge per
     physician or other recipient of the communication or of the sites to which
     the communication is directed, usually based upon the sponsor's
     communication application and annualized communications volumes, with
     annual minimum fees. As the number of national sponsors increase, the
     Company expects that incremental recurring revenue will increase as will
     profit margin as there is minimal additional expense incurred and most of
     the significant operations/expenses related to network usage are covered by
     fees paid by local sponsors. The Company recognizes the annual minimum fees
     prorated monthly until actual network communication fees exceed the
     minimum.

     RESULTS OF OPERATIONS

              The following discussion of the results of operations and
     financial condition of the Company should be read in conjunction with the
     Company's Consolidated Financial Statements and Notes thereto included
     elsewhere in this Proxy Statement-Prospectus. The table below sets forth
     certain items of revenue and expenses reflected in the Company's income
     statement and the percentages of total revenue represented by the items.

         SIX MONTHS ENDED JUNE 30, 1995 COMPARED TO SIX MONTHS ENDED JUNE 30,
         1994 (UNAUDITED)

                   NET SALES AND FEE REVENUE.  Total revenue increased $1.7
         million (27%) from $6.2 million in 1994 to $7.9 million for the first
         half of 1995.  Sponsor revenue under Network Service Agreements
         increased 67%, however, from $3.3 million in the first half of 1994 to
         $5.4 million in the first half of 1995, reflecting an increased number
         of operating networks, a greater number of sponsors participating in
         the networks and a substantial increase in the number of physicians
         with which networks are connected.  Sponsorship revenue under NSAs
         increased in each quarter for the last 10 fiscal quarters, again
         reflecting the growth of the Company's IMS MEDACOM/(R)/ networks.  The
         Company anticipates continued expansion of both the number of NSAs and
         networks in operation and plans to emphasize such growth in the next
         one to two years.

                   Revenue from Network License Agreements declined from $2.9
         million in the first half of 1994 to $1.4 million in the first half of
         1995.  The 1994 first half was exceptionally strong, reflecting
         recognition of substantial revenue from the sale of a network license
         for Hawaii in the first half of 1994 and several other smaller
         licenses.  In the first half of 1995, the Company completed only two
         license sale transactions which reflects the historical fluctuation in
         this revenue as network licenses sold in smaller markets are
         unpredictable in nature and generally require 12 to 18 months from the
         time the licensee initially indicates interest in a network until the
         sale is completed and the initial network installation is in place.

                   Network license service revenue increased from $69,000 in the
         first half of 1994 to $1.1 million in the first half of 1995,
         reflecting increased management service fees, implementation fees and
         recognition of a portion of initial license fees sold in previous
         periods.  Service revenue tends to reflect services provided to
         licensees and sponsors that became participants on networks in previous
         periods and therefor should tend to increase as the number of licenses
         for which IMS will provide network management increases and as the
         number of sponsors under NSAs increase.

                                       62

 
                   SALARIES AND BENEFITS.  Salaries and benefits increased
         approximately $3.8 million or 81% in the first half of 1995 compared to
         the first half of 1994, and due to only slightly increased revenue in
         the first half of 1995, salaries and benefits represented 107% of
         revenue in the first half of 1995 compared to 75% of revenue in the
         first half of 1994.  The substantial increase reflects an increase in
         the number of employees from 146 at the beginning of 1994 to 275 at the
         beginning of 1995.

                   FACILITIES AND RELATED EXPENSES.  Facilities and related
         expenses are composed of rent, equipment, maintenance and depreciation,
         telephone, utilities, insurance and taxes.  Facilities expenses
         increased $1.0 million over the first half of 1994 to $2.4 million for
         the first half of 1995, or 74%.  The Company incurred increases due to
         opening of additional administrative offices in Denver in January 1995
         and opening more field offices.  Rent and related facilities expenses
         in 1995 for the San Diego office closed at the end of 1994 were charged
         to reorganization in 1994 and are not included in the first half 1995
         facilities expenses, although such expenses were paid in 1995.
         Telephone expenses increased 137% over the comparable period in 1994,
         reflecting substantially increased network traffic.

                   SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and
         administrative ("SG&A") expenses include travel and entertainment,
         marketing, sales and promotion expenses and other uncategorized
         expenses.  SG&A expenses increased approximately $1.2 million, or 52%,
         in the first half of 1995 compared to the first half of 1994.  Travel
         and related selling expenses increased due to the Company's transition
         to a national sales force in late 1994 and other SG&A expenses
         increased as the level of activities rose due to the Company's growth.

         YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993

                   NET SALES AND FEE REVENUE.  Net sales and fee revenue
         increased approximately $10.1 million or 128% from 1993 to 1994.  The
         growth in net sales and fee revenue is attributable to an increase in
         the number of NSAs and to an increase in revenue per contract.  The
         number of hospital NSAs increased from 76 in 1993 to 109 in 1994, or
         43%, and other NSAs increased from 38 at the end of 1993 to 66 in 1994,
         or 74%.  Revenue from hospital NSAs increased from $5.1 million in 1993
         to $7.5 million in 1994, or 47%.  Revenue from other sponsor NSAs and
         from NLAs increased from $2.7 million in 1993 to $10.4 million in 1994,
         or 285%.

                   SALARIES AND BENEFITS.  Salaries and benefits increased $4.6
         million or 64%, for fiscal 1994 compared to fiscal 1993.  Salaries and
         benefits as a percentage of revenue were 66% in 1994 compared to 92% in
         1993 because revenue was substantially higher in 1994.  The increase in
         salaries and benefits was due to the addition of field, technical and
         corporate employees required to support the increase in NSAs,
         installation of NLAs and to enhance network software.  The Company also
         transitioned to a national sales force in late 1994, increasing the
         selling staff from eight at the end of 1993 to 14 at the end of 1994.

                   FACILITIES AND RELATED EXPENSES.  Facilities expenses
         increased approximately $1.5 million to $3.2 million in 1994, or 90%.
         These expenses increased principally from increased costs for rent,
         depreciation and telephone expenses, new field offices and depreciation
         from increased computer equipment purchases as a result of an increase
         in the number of sponsor contracts.  Telephone expenses, including long
         distance charges, increased 114% due to the large increase in the
         number of network messages transmitted over phone lines.

                   SELLING, GENERAL AND ADMINISTRATIVE.  SG&A were $5.8 million
         or 33% of revenue for 1994 compared to $2.6 million or 34% of revenue
         for 1993, representing an increase of $3.2 million, or 124%.  The
         increase included travel and related expenses which increased
         approximately 100% to $1.65 million, marketing sales and promotions
         which increased 58% to approximately $.8 million and executive training
         services in 1994 for which there were no similar expenditures in the
         prior year.  Substantially all the increases were related generally to
         the Company's increased business activity in 1994.

                                       63

 
                   COST OF SUBSIDIARY LITIGATION.  Litigation involving the
         Company, two subsidiaries and certain directors was commenced in 1992.
         The cost of this litigation was substantial and materially affected the
         Company's cash flow and loss for 1992, 1993 and 1994.  Costs of
         litigation, representing professional fees and expenses and the cost of
         indemnifying a director, were $1.7 million in 1993 and $785,000 in 1994
         when the litigation was substantially concluded.  The litigation
         resulted in judgment in favor of the Company and the directors
         following trials.  The Company is not currently involved in any
         material litigation.

                   REORGANIZATION COSTS.  In 1994, the Company closed its San
         Diego office and charged the costs to expenses for 1994.  Approximately
         $100,000 of the $479,000 of expenses relate to net leasehold expenses
         which will be paid over the remaining term of the lease and
         approximately $280,000 represents expenses and severance compensation
         to be paid in 1995 to the former chairman and founder of the Company
         who continued on as a director following the reorganization.

         LIQUIDITY AND CAPITAL RESOURCES

                   The Company has incurred and expects to continue to incur
         significant operating and net losses and to continue to generate
         negative cash flow from operating activities while it emphasizes
         development and enhancement of networks and until the Company
         establishes sufficient sponsor revenue for each network.  In view of
         the anticipated negative cash flow from operating activities and the
         cash required for the continuing development of the Company's products
         and services, the expansion of existing networks and the construction
         and acquisition of new networks, the Company will require substantial
         amounts of capital for the balance of fiscal 1995 and the foreseeable
         future from outside sources.

                   IMS had working capital of $617,000 at December 31, 1994
         compared to a working capital deficit of $612,000 at June 30, 1995.  At
         June 30, 1995, IMS had $1,318,000 cash and cash equivalents on hand
         compared to $1,358,000 at December 31, 1994.  This increase was
         attributable to sale of receivables remaining under NLAs, and
         borrowings from Lilly.  IMS's contract receivables at December 31, 1994
         was $6,803,000 compared to $3,103,000 at June 30, 1995, again because
         of sales of contract receivables.

                   The Company had an accumulated deficit of approximately $23.4
         million at December 31, 1994 and approximately $29.9 million at June
         30, 1995.  Since December 31, 1994, the Company has funded operations
         primarily through $4 million in borrowings from Lilly and $1.9 million
         from the exercise by Lilly of a warrant to purchase 375,000 shares of
         Series C Preferred Stock (see "SPECIAL FACTORS TO BE CONSIDERED -
         Background to the Merger"), and $4.3 million from the sale of
         receivables under network license and service agreements to financial
         institutions on a discounted cash flow basis.  In addition, the Company
         has used portions of a $1 million line of credit which is secured by
         guarantees of certain directors and of which there was no amount
         outstanding as of June 30, 1995.

                   The Company believes that the relationship with Lilly created
         by the Merger will add financial credibility to the Company as well as
         add direct financing from Lilly through either future debt or equity
         capital infusions from Lilly.  Consequently, the Company anticipates a
         more rapid growth pattern than if the Merger were not consummated.

                   If the Merger is not consummated, which is not expected, IMS
         would continue to fund its operations with revenue from operations,
         sale of equity securities, sale of contract receivables and potential
         debt financing.  The failure to obtain sufficient amounts from such
         future financing efforts would result in the delay or abandonment of
         some or all of the Company's development and expansion plans which
         could have a material adverse effect on the Company's business and
         competitive position.

                                BUSINESS OF IMS

                   Founded in 1985, the Company develops and operates
         computerized medical communication networks that link participants in
         the healthcare delivery system to deliver routine and specialized
         messages in automated format.  The Company's networks provide a
         practical means for healthcare providers and payers to develop
         integrated information delivery management programs.  Healthcare, and
         especially the individual physician's practice of medicine, generates
         prolific requirements for multi-location, multi-system clinical,
         financial and administrative communications and information transfer.
         The Company believes that it is a leading provider of physician-
         focused, multi-participant, multi-media, bi-directional automated
         healthcare communications through a common user connection based on
         total number of communications delivered, variety of communications,
         number of physician participants, number and variety of connected host
         healthcare information systems, number of institutions (hospitals,
         managed care plans, clinical laboratories, ancillary care providers and
         healthcare information and administrative services) and number of
         operational networks and markets served.

                   The first IMS medical communication network was deployed in
         1988.  Since that time, IMS has developed networks in more than 43
         areas across the United States.  IMS has pioneered the concept of
         "open" architecture (available on a fee-for-use basis regardless of the
         user's affiliation) medical communication networks (the "IMS
         MEDACOM/(R)/ Networks").

                   IMS MEDACOM/(R)/ Networks connect healthcare information
         systems and departmental workstations utilizing proprietary network
         controller software and proprietary message handling software on
         personal computers at the user's site.  IMS MEDACOM/(R)/ networks
         increase the timeliness and accuracy of clinical communications, ease
         the burden of compliance with managed care and financial transaction
         requirements and reduce the information management burden for
         physicians, hospitals and other network users.  Also, unlimited
         communication between all physicians in a given network is available.
         The Company estimates that over 30 million total messages were
         delivered over IMS MEDACOM/(R)/ Networks in 1994.

                   The Company's core set of three software connectivity tools
         are: RELAY/TM/, which provides a system integration of diverse formats;
         ComCenter, the network switch which distributes messages among network
         users; and PC-COM, the software on each workstation which enables the
         user to access the network.  These software components are installed as
         a network in each healthcare market area in which the Company operates.
         A local operations staff of IMS employees manages the connectivity of
         the various communications software of network users, provides on-going
         training and workstation support and works with network sponsors to
         continually expand their services and applications provided to
         physicians and other users over the network.

                   Physicians gain access to networks at no cost.  Network
         sponsors are healthcare institutions, organizations and services which
         communicate regularly with physicians in the normal course of business.
         Sponsors pay annual network communications or license fees that
         typically relate to the number of physicians the sponsor chooses to
         reach on the network.  As more sponsors pay for network connectivity,
         the Company receives additional license and implementation fees and
         more physicians are connected.  Growing numbers of sponsors and
         physicians on networks lead to increased usage and acceptance and,
         ultimately, revenue to the Company.

         INDUSTRY BACKGROUND

                   Changes and cost containment pressures in the nation's
         healthcare system are placing new demands on providers and payers.  An
         aging population, advances in technology and the rapid growth of
         managed care have all resulted in increased demand for the timely and
         cost-effective collection, analysis, management, sharing and
         communication of information among healthcare providers and between
         them and payers. This change has caused a reorientation of the role of
         healthcare information systems from transaction

                                       65

 
         processing of episodic health service events to active decision support
         and cumulative tracking and reporting of comprehensive, multi-point
         courses of care. In response, an entirely new sub-industry has been
         created-integrated healthcare communication networking.

                   The physician's office is now the focal point of hundreds of
         monthly communication "transactions."  Historically, the healthcare
         industry focused on automation of provider claims submissions.  In
         fact, in medical practices, there are multiple communications, clinical
         and administrative messages and information exchanges required to
         fulfill the service that results in just one payment claim submission
         to a payer.   While there are estimated to be approximately 2.5 billion
         claims that flow from providers to payers annually, the Company
         believes that the total physician-focused medical communications volume
         is eight to ten times as large.

                   Not only must physicians deal with increasing amounts of
         information, they also must manage and synthesize inputs from, and
         reply appropriately to, an ever more diverse group of other service
         providers, payers and intermediaries.  These institutions and referral
         services recognize the need to improve communication with physicians,
         the patients they serve and the employers who ultimately fund a
         significant portion of the medical services.  The driving force behind
         this need is concern for the timely delivery of quality patient care.
         In today's environment, healthcare depends upon efficient information
         management and communication transactions.

                   The Company estimates that nationwide there are 570,000
         private practicing physicians engaged in direct patient care within
         approximately 200,000 medical practices.  Approximately 50% of these
         physicians practice in the largest 50 markets.  Further, approximately
         70% of the practices are somewhat automated with either an in-office
         computer or a link into a computer service.  Most of these computers
         today can be characterized as medical practice management systems with
         applications limited to various levels of sophistication in patient,
         scheduling, billing and accounting processes.

                   While vitally important to the administrative operation of a
         medical practice, billing and patient account management activities
         address only a portion of a physician's practice automation and
         communication requirements.  Other automated systems and services
         should directly support the provision of clinical care, before, during
         and following the patient encounter.  Most of these communications are
         presently nonintegrated, nonautomated media: voice, printed text,
         facsimile, clinical graphic printouts and handwritten notations with
         the attendant problems of routing delays, filing mistakes, recipient
         unavailability, transcription errors and other mechanical management
         problems.  The Company's IMS MEDACOM/(R)/ Networks improve the
         physician's professional service environment by (i) simplifying
         information access, (ii) eliminating delivery delays, (iii) integrating
         diverse communications and data sources into a common and easy-to-use
         format at the point-of-care, and (iv) providing automated access to the
         full range of clinical referral and support services typically required
         by the physician.  Ultimately, communications with hospitals, other
         service providers and payers, such as insurance companies or managed
         care providers, are improved, thereby increasing efficiency and quality
         of care and helping to hold costs down.

                   Other attempts to address these challenges usually result in
         proprietary, single function automated communication between physicians
         and other entities (such as a laboratory or a managed care provider),
         with no ability or right to link with others.  The technologies have
         ranged from simplistic transaction telephone terminals, to dedicated
         fax machines, smart modem printers, uni-directional communication
         software protocols or the in-office installation of single purpose
         mainframe terminals or personal computers.  Because these efforts each
         addressed only the specific needs of one entity in linking with the
         physician and the applications were driven from the perspective of
         large institutional information systems departments, they are often
         characterized by difficulty of use and require that the physician's
         office staff install and learn to operate a variety of incompatible
         devices and communications protocols.  The result has often been
         limited deployment and minimal use.

                                       66

 
                   With the rapid emergence of managed care and the movement
         toward risk sharing or "capitated" provider payment methodologies,
         integration of healthcare delivery will be accelerated.  Essentially,
         healthcare payers are forcing healthcare providers to assume the
         economic risks of healthcare.

                   This change creates increased provider dependence upon
         information and multi-point communications.  There is now a demand for
         new and more sophisticated information processing systems at the point
         of care, accessible, as appropriate, by other providers and by payers.
         Basic systems which served practice automation during the past decade
         are of decreasing value in the evolving practice environment.  To
         participate fully in the managed care world, physician offices must be
         able to record, store, analyze and distribute clinical information,
         automate the processing and communication of third-party reimbursement
         transactions, validate patient eligibility and comply with health plan
         formulated treatment regimens, pharmaceutical therapies and
         governmental regulation.

                   Medical practice is further complicated by the formation of
         new multi-provider integrated delivery systems ("IDS") to address full
         capitation of the medical treatment risk for entire patient
         populations. IDS' create a new need for automated medical
         communications to coordinate care across diverse and otherwise
         unrelated providers.  With integrated delivery, goals of payers,
         provider institutions and hospitals become aligned with an emphasis on
         coordination, cooperation, information sharing and mutual
         accountability to achieve the organizational, operational and financial
         goals of the participants.

                   Physician practices, and in particular primary care
         practices, are positioned at the apex  for implementing the IDS
         strategies.  The Company believes that these industry factors will
         continue to position physicians as the focal point for constructing
         true integrated healthcare delivery and cause hospitals, payers and
         physician organizations to seek access to open architecture, automated
         medical communication networks which fulfill the efficient
         communication needs of all participants.

         STRATEGY

                   The Company's objective is to be the leading provider of
         physician-focused automated medical communication networks and services
         which deliver decision-critical information to the healthcare industry.
         IMS MEDACOM/(R)/ Network services are designed to improve healthcare
         information technology to assist physicians, other healthcare providers
         and payers to better manage all aspects of patient care through the
         application of efficient, accurate and timely communication.  The
         Company's strategy includes the following key elements:

         .    Focus on Physician Office Requirements: The Company attracts
              physician participation on networks by emphasizing ease of use,
              minimal investment and immediate and relevant value to the
              practice.  There is no charge to physicians for the Company's
              software, installation, training, on-going support or messages and
              communications services.  A physician can use an existing office
              computer to serve as the IMS MEDACOM/(R)/ Network communications
              workstation ("NCW") with the Company's PC-Com/TM/ software.  The
              Company believes that its physician focus creates an on-going
              relationship and alliance that will accelerate the attraction of
              network sponsors and generate new network uses and applications
              with potential revenue sources for the Company.

         .    Establish IMS MEDACOM/(R)/ Networks in Additional Markets: The
              Company is working to develop owned and operated IMS MEDACOM/(R)/
              Networks in the largest 50 markets (based on numbers of practicing
              physicians); and become the "utility" for computerized medical
              communications across the entire spectrum of healthcare delivery
              in the market area.  In smaller markets, the Company licenses the
              operation of its IMS MEDACOM/(R)/ Networks to one or more
              qualified local operators.

         .    Add Additional Sponsors to Existing Networks: In the largest 50
              markets in which the Company establishes IMS MEDACOM/(R)/
              Networks, the addition of local sponsors generates both
              significant financial leverage and attracts additional physician
              participation which in turn increases the

                                       67

 
              importance of the network in the local market.  The addition of
              national sponsors which communicate with physicians across several
              IMS MEDACOM/(R)/ Networks also add leveraged revenue for the
              Company in both operated and licensed networks.

         .    Technology and Services Leadership:  The Company has established a
              single method of access for physicians and other users.  This
              method combines open architecture, ease of use and bi-directional
              communications and employs a common look and feel for network
              users.  The system is simple, utilizes whatever computer operating
              system is in place and is easily upgradable.  The Company intends
              to extend this presence and reputation for successful new service
              integration into higher speed transmissions, more complex system
              interfaces and an array of physician "desktop" information
              management services.

         HEALTH CARE INDUSTRY INFORMATION NEEDS

                   Today 60% of health care occurs outside the hospital and 80%
              of health system patient encounters begin in the community
              physician's office.  Consequently, a great deal of patient care
              information must be relayed in a timely manner between
              geographically disparate locations.  For example, primary care
              physicians confer with specialists; pharmacists communicate with
              physicians; managed care providers require pre-authorizations
              before procedures are scheduled and referrals authorized; and
              hospital staff consult with physicians, insurers, home care
              agencies and other providers.  The volume of information that must
              be exchanged within a health care community is increasing
              exponentially and the stakeholders in health care systems are
              becoming more diverse.

                   As early as 1985, there were attempts to provide
              communication links between physicians and hospitals.  Most of
              these early attempts failed for a variety of reasons:

         .    the systems were closed, requiring expensive investments in
              proprietary equipment that was limited in use and cumbersome to
              access;

         .    the networks appeared to be self-serving because they were
              installed by hospitals or other entities for limited specialized
              uses; and only provided for hospital-physician communication; and

         .    the information available over the network did not include
              important clinical data such as test results or X-rays, and lacked
              features such as physician-to-physician voice messaging,
              electronic signature and continuing medical education programs.

                   IMS created IMS MEDACOM/(R)/ Networks to fulfill the need for
         an effective, easy-to-use communication system available to all users
         on all equipment.  IMS's proprietary networks improve the efficiency
         and effectiveness of medical communication and information management.

         IMS MEDACOM/(R)/ NETWORK

         Design

                   A network to support the electronic exchange of text, voice,
         graphics and images in the health care industry must be highly reliable
         and provide connectivity to any computer system in use by both
         subscribers and sponsors.  The Company provides this service through
         proprietary software which can run on most hardware, and which is
         delivered by a full range of field operational services, all of which
         it has developed since 1985.

                   Each IMS MEDACOM/(R)/ Network has at its core the ComCenter,
         a communications controller and switch which hosts proprietary IMS
         software.  The participants in a local healthcare delivery system can
         be connected as a network through the ComCenter to automate routine and
         specialized communications.  The network converts transactions such as
         clinical results reporting, referral notifications, admission forms,
         medical transcriptions, consultant reports, clinical monitor tracings,
         medical records,

                                       68

 
         calendars, prescriptions, third party claims and managed care encounter
         protocols from mail, fax, phone or courier distribution to a common
         computerized, bi-directional pathway. Physician offices (subscribers)
         join the network at no cost for the service when the Company's
         proprietary workstation software ("PC-COM") is installed on their
         computer. Healthcare institutions, such as hospitals, pay annual
         communications and license fees to become network sponsors with the
         right to communicate electronically with their designated group of
         physicians. The sponsors link into the local IMS MEDACOM/(R)/ Network
         using both interfaces to their own proprietary automated systems with
         the Company's RELAY/TM/ software and an unlimited site license for PC-
         COM to enable in-house computers across their organization to become
         network communication workstations ("NCWs"). Each institutional
         department or function of the hospital can format standard automated
         transactions for an unlimited range of routine communications to
         physicians or other network participants using the Company's
         proprietary computer protocols (Script) and imbedding the Scripts in
         the subscriber NCWs under a multi-level directory-driven communications
         module.

                   The ComCenter maintains the network directory of users,
         message ordering system and transaction log.  In the largest 50
         markets, each ComCenter is installed in a centrally located office
         leased by the Company that houses an IMS network staff which develops,
         coordinates and supports the network.  The network staff also provides
         training with scheduled classes covering all aspects of network use and
         benefits along with new sponsor and subscriber orientation and
         specialty training covering new sponsor applications or network
         enhancements.

                   The networks do not process data or provide and operate
         value-added data management or storage applications.  The IMS strategy
         is focused on connectivity, message delivery, automated message
         handling systems, facilitating functional systems integration
         initiatives and enabling the practical implementation of multi-provider
         organized delivery systems.  During 1995 the Company deployed its
         ComCenter NT software, based upon the MicroSoft Windows NT/(R)/ network
         operating system, to enhance its core strategy, gain flexibility in
         scaling ComCenters and to add communications options such as on-line
         sessions, "near-time" automated response host inquires and single point
         access for national sponsors communicating across multiple networks.

                   The IMS MEDACOM/(R)/ Network provides multi-platform
         functionality.  The RELAY/TM/ software enables the network to permit
         sponsors to automate virtually any communication to any network user
         from any host computer system that can generate a print stream.
         Utilizing RELAY/TM/, the Company has connected networks with healthcare
         information systems sold by all of the major computer or software
         vendors.  The majority of the NCWs on the Company's various networks
         are IBM-compatible, DOS-based personal computers, either stand-alone
         units or as participants on a local area network.  The Company's
         software can also be installed on computers operating under other
         operating systems, such as UNIX, ZENIX and AIX.  The Company has
         designed a Microsoft Windows/(R)/ based operating system version for
         its software which is scheduled for release to network users during the
         first half of 1996.

                   A key feature of IMS MEDACOM/(R)/ Networks is that
         communication for every NCW is bi-directional.  As opposed to general
         purpose E-mail systems, or special purpose EDI applications (such as
         electronic claims submission), the IMS MEDACOM/(R)/ Network permits a
         message to be launched to or from a designated NCW.  In this way,
         network participants are assured that their network messages have been
         received at the destination and the receiver can process the message
         instantly because it is resident as electronic media on the NCW.

                   The IMS MEDACOM/(R)/ Networks connect participants using
         modems and basic phone lines, and because the highest volume message is
         usually clinical results from a local source, the majority of
         communication occurs within the telephone company's local area,
         eliminating most long distance charges for network participants.  Where
         higher-speed bandwidth (such as fiber optic cable) is available and
         desired by network participants, the entire suite of IMS MEDACOM/(R)/
         Network software is compatible with other transmission media.

                                       69

 
         Using an IMS Network

                   A key design consideration for the IMS MEDACOM(R) Network is
         simplicity of use.  The use of menus, help facilities, graphic
         highlights and consistent colors contributes to a high level of
         acceptance and utilization by physicians, office staff and other
         participants.

                   Using the Company's updated operating software, information
         sent on a network is routed over dial-up telephone lines through a
         network ComCenter computer which utilizes Microsoft Windows NT(C)
         client-server technology and hosts IMS message switching software. The
         updated network ComCenter allows for a wide variety of connection and
         integration with the many information systems currently being used in
         the health care industry and lends itself well to the open architecture
         networks of IMS.

                   Each Network participant requires a computer workstation,
         which is an IBM-PC or fully compatible DOS personal computer (or other
         computer and operating system), running PC-Com/TM/, the IMS MEDACOM(R)
         communications software.  The network's multi-platform functionality
         allows Network participants to use existing computer equipment as
         Network workstations.  These workstations communicate with the network
         ComCenter through modems and phone lines.

                   To communicate using an IMS MEDACOM(R) Network, a sender
         creates a message and sends it from his personal computer. Using IMS's
         proprietary software, his computer then automatically dials the phone
         number of the network ComCenter and sends the message.  Once the
         ComCenter has received a message, it checks its directory to ensure
         that the message is being sent to the appropriate computer and then
         dials the phone number of the recipient.  When that computer answers,
         the ComCenter automatically forwards the message to the recipient's
         computer.  Unless using one of the on-line options, the sender is not
         directly linked to the recipient computer.  This solves most of the
         security issues associated with interactive electronic communications.

                   Messages are automatically delivered to the recipient's
         computer hard disk drive 24 hours per day, without operator
         intervention.  The network ComCenter maintains a directory of all of
         the Network sponsors and subscribers which can be easily updated.  In
         addition to the name, address and office telephone number of the
         physician, directory space is provided to list the physician's practice
         specialties and other profile information.  Directory updates are
         automatically distributed to all IMS MEDACOM(R) Network members.

              Participants' workstation computers are not restricted to Network
         functions.  The network software operates "in the background" while the
         computer may be used for other clinical, financial and administrative
         applications.  If an IMS MEDACOM(R) message is received while the
         computer is in use, a waiting messages display appears in the upper
         right-hand corner of the computer screen.  The operator can quickly
         read the new message without leaving the application he or she is in at
         that time.  In a similar fashion, after a message has been created, the
         operator can continue with other work while the transmission to the
         network ComCenter takes place in the background.

              If the operator chooses to process waiting messages, a screen is
         displayed that shows all of the new messages, who sent them, to whom
         they are addressed and the date and time at which they were sent.  The
         subject of the message is also displayed.

         Customizing the Network

                   One of the powerful features of the IMS MEDACOM(R) Network is
         that it allows for network messages to contain attached data files,
         such as voice messages, medical images or text from a word processor.
         This permits the recipient to handle the appropriate disposition of the
         transmitted material.  Text files, such as those that might come from a
         word processor, can be printed or copied to a disk for processing.
         After the operator has printed the message and processed any attached
         files, the system can

                                       70

 
         automatically send an acknowledgment to the message originator,
         indicating that the message was received and processed.  Message
         forward and reply functions are also available.

                   Customized screens can be created for different types of
         messages, such as hospital pre-admissions, patient referrals and
         eligibility.  In addition, a network sponsor can elect to broadcast a
         message to all its participants on the network or to create a list of
         people to whom a single message is to be sent.  This latter facility
         might be used, for example, by a hospital to send the next day's
         surgery schedule to all surgeons.

         Sources of Network Revenue

                   There are generally three levels of participation on IMS
         MEDACOM(R) Networks:  national sponsors, local sponsors and physician
         subscribers.  Sponsors pay various fixed and message related fees to
         "communicate" with selected physician Subscribers or other network
         users.

                   Local Sponsors.  Local sponsors include local organizations
         that desire to use a network to improve the quality of their services
         to physicians, improve the efficiency of their operations and
         strengthen relationships with physicians or other users.  Such
         organizations include hospitals, clinics, specialists, imaging centers,
         home care agencies, independent pharmacies, transcription services,
         etc.  These entities enter into one to five year network services
         agreements and pay annual fees and other charges for network use.

                   National Sponsors.  National sponsors include healthcare
         organizations or providers that desire to communicate with a wide range
         of physicians or other network users in multiple markets.  Such
         organizations include pharmaceutical companies, clinical laboratories,
         pharmacy chains, managed care/insurance companies, medical publishers,
         etc., and usually are also sponsors of more than one, and generally
         all, other IMS medical information networks located throughout the
         United States.

                   Physician Subscribers.  Each physician or medical practice is
         a key influence or client for a wide range of local and national
         sponsors.  Physician subscribers create revenue by attracting local and
         national sponsors which pay to use the network to communicate with
         subscribers.  Although some sponsors' fees are dependent upon the
         number of physicians with which communication is sought, no network
         revenue is provided by physicians.

         Network Support

                   The Company provides extensive centralized network
         monitoring, field and sponsor staff training, technical implementation
         resources and real time support from its Golden, Colorado offices.  The
         network services division delivers: (a) network design services
         including on-site sponsor requirement evaluations and RELAY/TM/
         specification development; (b) RELAY/TM/ and other interface
         programming, testing and installation; (c) call-in support with direct
         technician interfaces who operate an automated problem logging,
         tracking, resolution and follow-up system; and (d) a national training
         center, housed in a separate, purpose-built facility with a curriculum
         that covers a Company orientation, the industry, the Company's
         technology and products, policies and procedures and a variety of
         application and programming credentialing.

         (3)  Operated under a joint venture or similar arrangement.  
              See "Co-Ventures" below.

                   In markets where IMS MEDACOM/(R)/ Networks are in place, the
         Company estimates that there are around 150,000 physicians in practice,
         of which 18% are subscribers to an IMS network.  Physician subscribers
         connected to IMS MEDACOM/(R)/ Networks have grown from 845 at December
         31, 1991 to 14,713 at December 31, 1994 and 27,433 at July 31, 1995.

                   At July 31, 1995, IMS and networks operated by IMS or
         affiliates had sponsorship agreements with 102 sponsors, with remaining
         terms of two to five years.  Eighty-three of the sponsors were
         hospitals or hospital systems, managed care providers or payers, six
         were laboratories, and five other sponsors.  In addition, IMS has
         network license agreements with 20 licensee hospitals or healthcare
         organizations, which authorize the licensee to use IMS network software
         to set up and operate a proprietary network in smaller markets.  IMS
         and national sponsors are usually authorized to communicate with users
         of the licensee's network.  The licensee frequently retains IMS to
         manage its network or to provide various ancillary services.  Sponsors
         and licensees each pay initial implementation fees, annual fees and
         other charges for specialized or additional services for fixed contract
         terms, generally five years, renewable thereafter for negotiated fees.

                   Pursuant to each venture arrangement, an open network is
         established and operated as a separate business consistent with the
         operation of other networks by IMS in other areas.  Local sponsors
         contract with the venture for network participation.  IMS and the
         venturer are generally reimbursed for services provided to the venture
         and operating profits are shared according to ownership interest.
         Revenue from national sponsors who contract with IMS is shared between
         IMS and the venture entity.  Financial information from these entities
         is included with the consolidated financial information for IMS and its
         subsidiaries.

         PRODUCT DEVELOPMENT

                   The healthcare information systems industry, particularly
         communications networking, is characterized by rapid change and a
         continuing need for high level of development and improvement of
         software and services.  In order to maintain and improve new sponsor
         participation on networks, increase physician participation and
         accelerate the revenue per sponsor, the Company believes that its
         networks must continue to be viewed as technologically competent,
         functionally flexible and expandable, ubiquitous in

                                       73

 
         systems integration capability and powerful in terms both of
         encompassing the full range of sponsor automation requirements and
         adding increasing value at the physician's desktop.

                   The implementation of the ComCenter NT technology has opened
         up a broad range of product development opportunities for the Company.
         Most of these development activities are responses to requests or
         suggestions from current network participants.  These include data file
         level host system integration; a Windows/TM/ version of the PC-Com
         (NCW) software; enhanced UNIX functionality; broader LAN integration;
         bridges to the most popular institutional E-Mail systems; real-time
         remote display of clinical monitor activity (ICU, CPU, fetal, etc.);
         enterprise wide master indexing of patient activity integrated from
         outside the institution into the physician's office; a full set of
         financial/claim EDI activities as well as practice management system
         interfaces; and enhanced network access using single point connection
         into multiple ComCenters of more than one network.

                   The Company also recognizes that technology and service
         venture alliances with major corporations in the healthcare, technology
         and communications fields can bring a valuable level of product
         development expertise and opportunity to its networks.  The Company has
         been approached by national healthcare support service vendors which
         desire to create enhanced value applications of their core activities
         by adding a network communications capability.  Arrangements have been
         consummated for a technology and service relationship in claims
         processing; for point-of-service material management; and  for
         automated physician/pharmacy communications.

                   As of August 31, 1995, approximately 215 computer programmers
         and technical personnel of the Company and ventures with which the
         Company is affiliated are involved at different times and in varying
         degrees, in product development and enhancement and software support.
         IMS MEDACOM/(R)/ is committed to identifying existing software
         systems/programs and/or developing new programs that bring added value
         to IMS MEDACOM/(R)/ Network participants.  Many of IMS's network
         applications were developed in cooperation with health care providers
         and payers. The Company intends to continue this strategy of developing
         services in cooperation with key customers in targeted sectors.  No
         assurance can be given that the Company will be able to develop such
         services or products nor that they will have general acceptance in the
         marketplace.

         SALES AND MARKETING

                   The Company markets its services and software licenses
         through a direct sales force consisting, as of July 31, 1995, of 15
         direct field sales executives located throughout the United States,
         regional sales vice presidents for both the eastern and western United
         States, and a Vice President of Technical Sales Support.  The Company's
         sales offices are located in Arizona, California, Georgia, Illinois,
         Massachusetts, Ohio, Pennsylvania, South Carolina and Texas.  The sales
         force is managed by a Senior Vice President who is also a member of the
         Company's Management Committee.  The sales executives are supported by
         the field operations General Managers and the Director of Operations
         resident at each IMS MEDACOM/(R)/ Network.  Also, the sales staff
         receives marketing and administrative support from the Company's
         strategic development division which includes a director of marketing,
         media relations manager and industry marketing specialists.

                   The Company generates sales through referrals from sponsors
         and physicians, healthcare information systems consultants, industry
         seminars and trade shows, news articles in the trade and general
         business press, direct mail campaigns and advertisements in trade
         journals.  In addition, the Company's relatively large installed
         physician base attracts direct inquiries from national or regional
         healthcare service organizations that desire an automated
         communications link with their affiliated physicians or other
         providers.  Also, as a result of consolidations and the restructuring
         of local/regional healthcare delivery into integrated systems, the
         Company's base of installed institutions provides leveraged
         introductions to a number of new sales prospects.

                                       74

 
                   The principal potential sponsors for the Company's services
         include the largest health care providers and payers.  The Company has
         identified six target sponsor groups within the health care sector:
         hospitals, clinical laboratories, pharmaceutical companies, pharmacies,
         managed care providers, and other provider/payers.

                   No single customer accounted for more than 10% of the
         Company's total revenues for the year ended December 31, 1993.  One
         customer, a hospital system licensee under an NLA, accounted for
         approximately 19% of the Company's total revenue in its fiscal year
         ending December 31, 1994.

         COMPETITION

                   The health care communications industry is competitive.  Many
         hospitals, third party administrators, claims processing organizations,
         hospital systems vendors, systems integrators, insurers, managed care
         organizations, and a few small companies provide physicians with some
         form of communications link to one or more specific organizations.
         Major companies which have provided network systems to the health care
         industry include Baxter International (through its IBAX subsidiary),
         McDonnell Douglas, IBM through the IBM Information Network, Physicians
         Computer Network, Healthworks Alliance, Inc. and AmeriTech's Health
         Network Ventures. In addition, certain companies have expressed an
         intention to provide communications solutions to the health care
         industry, many of which have substantially greater resources than the
         Company.

         EMPLOYEES

                   As of August 31, 1995, the Company had 261 full-time
         employees, of which 175 are technical and engaged in maintaining or
         developing IMS products or services, 19 are marketing and sales, and 36
         are involved in administration and finance and 31 provide non-technical
         operation support in IMS business units which operate various networks.
         In addition, the Company's network ventures employ an additional 51
         people.  None of the Company's employees is represented by a union.
         The Company believes that its relationship with its employees is good.

         PROPERTIES

                   The Company's corporate offices are located at 15000 West
         Sixth Avenue, Golden, Colorado.  These premises are leased pursuant to
         a lease agreement which expires on January 31, 1998 and has a renewal
         term of five years.  The lease covers approximately 23,500 square feet
         of office space for which the Company pays annual rent of $142,400.
         The Company also leases approximately 42,500 square feet of additional
         office space in 21 offices throughout the country where the network
         provides service.  These offices range in size from approximately 700
         square feet to 3,000 square feet.  The Company pays annual rent in the
         aggregate amount of approximately $605,300 for this space.

                   The Company plans to lease space from time to time as it
         establishes new networks. Other than such anticipated space, the
         Company believes that its facilities are adequate for its present
         operations.

   (2)  Exercised warrants to purchase 27,000 shares at $2.50 per share.



         COMPENSATION OF DIRECTORS

             All directors are reimbursement for actual out-of-pocket expenses
        incurred in connection with attending meetings.

        LIMITATIONS ON LIABILITY OF OFFICERS AND DIRECTORS

             The Company's Amended Articles of Incorporation prior to the Merger
        and the New By-Laws following the Merger, each contain a provision
        eliminating or limiting director liability to the Company and its
        shareholders for monetary damages arising from acts or omissions in the
        director's capacity as a director.  The provisions do not, however,
        eliminate or limit the personal liability of a director (i) for any
        breach of such director's duty of loyalty to the Company or its
        shareholders, (ii) for acts or omissions not in good faith or which
        involve intentional misconduct or a knowing violation of law, (iii)
        under the Colorado statutory provision making directors personally
        liable, under a negligence standard, for unlawful dividends or unlawful
        stock purchases or redemptions, or (iv) for any transaction from which
        the director derived an improper personal benefit.  This provision
        offers persons who serve on the Board of Directors of the Company
        protection against awards of monetary damages resulting from breaches of
        their duty of care (except as indicated above).  As a result of these
        provisions, the ability of the Company or a shareholder thereof to
        successfully prosecute an action against a director for a breach of his
        duty of care is limited.  However, the provisions do not affect the
        availability of equitable remedies such as an injunction or rescission
        based upon a director's breach of his duty of care.  The Commission has
        taken the position that these provisions will have no effect on claims
        arising under the federal securities laws.

        CERTAIN TRANSACTIONS

             The Company has issued warrants to purchase 10,000 shares
        (aggregate) of its common stock to eight directors of the Company as
        consideration for their guarantee of the Company's revolving line of
        credit.

             During 1993 and 1994, the Company paid $61,000 and $125,000,
        respectively, to David R. Holbrooke, a director, as reimbursement for
        costs and expenses incurred by him directly or indirectly in connection
        with certain litigation or claims related to IMS-NET of Northern
        California, Inc. and related matters, concluded in early 1995, in
        accordance with obligations of the Company to provide indemnification
        for such expenses.

             The Company's founder and former Chairman, President and Chief
        Executive Officer, John A. McChesney, was an employee and maintained an
        office for the Company near San Diego, California through 1994. In early
        1995, Mr. McChesney resigned as an officer and employee of the Company,
        but remained as a director. In connection with the change, the Company
        agreed to continue Mr. McChesney's compensation through 1995, to pay
        certain office expenses incurred in closing the San Diego office and to
        pay office rent through June 1995.  As a result, the Company charged
        $479,439 to expenses of reorganization in the fourth quarter of 1994,
        including amounts to be paid to Mr. McChesney in 1995.  In connection
        with the resignation, Mr. McChesney has entered into a noncompetition
        and confidentiality agreement with the Company.

             The Company advanced Kevin Green, the Company's President and Chief
        Executive Officer, approximately $90,000 in connection with his
        relocation from Phoenix, Arizona to Golden, Colorado in June 1995.  Mr.
        Green repaid the Company $60,000 of the advance and the balance was

                                       83

 
        deemed by the Compensation Committee of the Board of Directors to be
        relocation expense payable by the Company.

             Kevin Green has an employment arrangement with the Company's Board
        of Directors, completed in connection with his relocation to Denver in
        June 1995, which includes the obligation of the Company to pay him a
        severance payment equal to 24 months compensation at the rate of
        compensation then paid to him, in the event, upon a change of control of
        the Company (such as the Merger), Mr. Green reasonably determines that
        due to circumstances which have changed as a result of the change of
        control he is unable to perform his services as the Chief Executive
        Officer and President of the Company in the manner in which he was
        expected to perform such services prior to the change of control.

             In 1994, the Company sold software and equipment valued at $177,500
        to RMBA Associates, a company owned by Robert M. Bryce, a director of
        the Company at that time.  RMBA resold these assets and other services
        of RMBA to a client which operates an IMS MEDACOM/(R)/ Network to which
        the Company provides services.

             In 1993, David Holbrooke, a director of the Company advanced the
        Company $250,000.  In addition, three directors (Robert Bryce, David
        Holbrooke and Charles Brown) each advanced $75,000 to the Company in
        1993.  These advances bore interest at prime plus 3% annually, were
        secured by assignments of cash flows, and were repaid in 1993.

             In January 1994, the Company issued warrants to purchase 79,302
        shares of Company Common Stock at $4.00 per share to John McChesney as
        compensation for guarantees of certain company obligations in prior
        years and repaid $166,938 to Mr. McChesney for advances made to the
        Company in prior years.

             In December 1994, the Company exchanged  4,000 shares of Company
        Common Stock and 2,000 warrants to purchase Company Common Stock for
        each of the 81 outstanding limited partnership interests in a limited
        partnership of which a subsidiary corporation was the general partner.
        The partnership held an exclusive license to operate an IMS network in
        Colorado.  Seven of the Company's directors and three other officers of
        the Company were also limited partners in the partnership and held a
        total of 32 partnership interests, in exchange for which the Company
        issued 128,000 shares Company Common Stock and warrants to purchase
        64,000 shares at $5.00 per share.  The exchanges with each of the
        Company offices and directors were on the same terms as the exchanges
        with each of the other 37 nonaffiliated limited partners.


                              AMENDMENT TO THE IMS
                        1994 EMPLOYEE STOCK OPTION PLAN

                   On April 22, 1995, subject to shareholder approval, the Board
         of Directors of IMS approved an amendment to the 1994 Plan increasing
         the number of shares of common stock issuable under the 1994 Plan from
         400,000 shares to 838,600 shares which equals the total number of
         options previously granted under the 1994 Plan.  Under the proposed
         amendment the first sentence of Section 2 of the 1994 Plan would be
         amended to read as follows:

                   "The number of shares of the Company's No Par Value Common
                   Stock ("Common Stock") which may be optioned under this Plan
                   is 838,600 shares."

                   The other terms of the 1994 Plan would remain unchanged.
         Approval of the Merger by IMS shareholders will be deemed to include
         approval of the proposed amendment.  Following the Merger,

                                       84

 
         no additional options will be granted under the 1994 Plan.  The
         description of the proposed amendment to the 1994 Plan is a summary and
         does not purport to be fully descriptive.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Integrated Medical Systems, Inc.:


We have audited the accompanying consolidated balance sheet of INTEGRATED
MEDICAL SYSTEMS, INC. (a Colorado corporation) and subsidiaries as of December
31, 1994, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the two years in the period ended December 31,
1994. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Integrated Medical
Systems, Inc. and subsidiaries as of December 31, 1994, and the results of their
operations and their cash flows for each of the two years in the period ended
December 31, 1994, in conformity with generally accepted accounting principles.

As explained in Notes 2 and 4 to the consolidated financial statements,
effective January 1, 1993, the Company changed its method of accounting for
income taxes.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

                               DECEMBER 31, 1994
                               -----------------
                (Including Notes Applicable to Unaudited Periods
                for the Six Months Ended June 30, 1995 and 1994)


(1)  ORGANIZATION AND LIQUIDITY
     --------------------------

     Organization
     ------------

     Integrated Medical Systems, Inc., ("IMS" or the "Company") develops and
markets medical communication networks and related products and services to
hospitals, managed care companies, clinical laboratories and other healthcare
organizations throughout the United States.

     Merger
     ------

     On August 2, 1995, the Company and Eli Lilly and Company ("Lilly") signed
an Agreement and Plan of Merger through which Lilly will acquire 100% of the
Company's common stock.

     Liquidity
     ---------

     Since its inception, the Company has incurred significant losses from
operations, cash flow deficits and had an accumulated deficit at December 31,
1994 and June 30, 1995 of approximately $23.4 million and $29.9 million,
respectively.  Through December 31, 1994, the Company relied on the sale of
preferred and common equity on capital contributions from joint venturers to
fund operating losses.  In the six months ended June 30, 1995, the Company
raised approximately $4.7 million from the exercise of Series C preferred stock
purchase warrants and from the sale of the rights to the remaining payments due
under certain network license agreements (see Notes 8 and 10) and through August
28, 1995 Lilly has provided loans to IMS of $5 million (see Note 3).  In
addition to ongoing sales of network licenses and service agreements, funding
through the sale of equity, the sale of network license contracts receivable or
the issuance of debt instruments, which management believes will be available in
1995, will be required to fund planned 1995 operations and network expansion.
As of December 31, 1994, the Company has working capital of approximately
$617,000 and has cancelable and noncancelable network services agreements, joint
venture agreements and agreements for the sale of licenses of approximately $44
million, net of receivables sold subsequent to year end.  Of this amount,
approximately $34 million will be collected over the next three years at the
rate of approximately $14 million, $11 million and $9 million in each of these
years, respectively.

     In management's opinion, these events will provide sufficient cash
resources to fund operations through fiscal 1995. To the extent these events do
not provide sufficient cash flow, management believes Lilly will continue to
provide the funding necessary for the Company to continue its development and
expansion until it is self sufficient.

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     ------------------------------------------

     Unaudited Financial Statements
     ------------------------------

     The consolidated financial statements and related notes to consolidated
financial statements as of June 30, 1995, and for the six months ended June 30,
1994 and 1995, are unaudited.  In the opinion of management, the unaudited
consolidated financial statements reflect all adjustments necessary for a fair
presentation.  All such adjustments were of a normal and recurring nature.

     Principles of Consolidation
     ---------------------------

     The accompanying consolidated financial statements include the accounts of
IMS and the following subsidiaries:

   (A) 100% owned by IMS-Net of Northern California, Inc.
   (B) IMS-Net of Colorado, Inc. was the 1% General Partner of this partnership
       which was dissolved as of December 31, 1994 (see Note 7).
   (C) IMS's indirect ownership interest through its wholly owned subsidiary.
   (D) The dissolution of these entities was in process at December 31, 1993
       and completed in 1994.
   (E) As of May 31, 1993, IMS purchased the remaining 35% limited partner
       profits interest in CHCN, L.P. for $300,000 and dissolved the
       partnership.
   (F) As of December 31, 1994, the outstanding 49% minority stock interest in
       IMS-Net of Northern California, Inc. ("Norcal") was retired by Norcal,
       thereby increasing the Company's interest from 51% to 100% (see Note 6).
   (G) IMS ownership interests as of June 30, 1995 are the same as December 31,
       1994 with the exception of the purchase of the remaining 3% of IMS-Net
       of Kansas City, Inc., to bring the IMS ownership to 100%.

   (H) Several of the entities listed above are governed by shareholders'
       or operating agreements which contain buy/sell provisions.  These
       provisions give the Company and the joint owners of these entities the
       right to initiate 

                                      F-11

 
        buy/sell elections relating to the entities' ownership. The price of the
        exchanges are at fair market value or as specifically defined in the
        agreements.

     All majority owned and controlled subsidiaries are consolidated and all
significant intercompany accounts and transactions have been eliminated in
consolidation.

     Cash Equivalents
     ----------------

     For purposes of the statements of cash flows, the Company considers highly
liquid debt instruments purchased with original maturities of three months or
less to be cash equivalents.

     Revenue Recognition
     -------------------

     The Company follows the provisions of the American Institute of Certified
Public Accountants Statement of Position 91-1, "Software Revenue Recognition".

     The Company licenses software under long-term network license agreements.
License fee revenue is recognized when the network is operational, customer
acceptance has occurred and all significant obligations have been satisfied.

     Post-contract support ("PCS") activities, including software updates and
maintenance, are provided to customers either as part of a network license
agreement or under a separate network license service agreement.  When PCS is
provided as part of a network license agreement, the Company allocates a portion
of the network license agreement fee to PCS activities.  The portion of the fee
allocated to PCS activities is based on the pricing of separate network license
service agreements.  All PCS revenue is recognized ratably over the period such
activities are provided.

     The Company also generates revenue from network service agreements.  Under
these agreements customers are provided network access, network communication
and installation.  Fees are typically paid quarterly in advance and recognized
as revenue ratably over the service period.

     Third-party joint venture fees resulting from the formation of consolidated
subsidiaries are recorded as capital contributions from joint venturers.
 
     Contracts Receivable and Deferred Contract Revenue
     --------------------------------------------------

     Contracts receivable are comprised of amounts due the Company under network
services and network license agreements for implementation and network access
fees.  Revenues associated with advance payments received under network services
agreements are deferred and recognized ratably over the period services are
performed.

     Equipment and Furniture
     -----------------------

     Equipment and furniture are stated at cost.  Depreciation and amortization
is provided using the straight-line method over the estimated useful lives of
the assets, ranging from 2 to 10 years.

                                      F-12

 
     Income Taxes
     ------------

     Effective January 1, 1993, the Company implemented the provisions of
Statement of Financial Accounting Standards No. 109 ("SFAS 109"), "Accounting
for Income Taxes".  SFAS 109 utilizes the liability method and deferred taxes
are determined based on the estimated future tax effects of differences between
the financial statement and tax bases of assets and liabilities and net
operating loss carryforwards given the provisions of enacted tax laws (see Note
4).

     Net Loss Per Share
     ------------------

     Net loss per share is computed on net loss less preferred stock dividends
and the weighted average number of common and common equivalent shares
outstanding during the year.  All outstanding stock options and warrants were
excluded from the computation because they were antidilutive.

     Software Development Costs
     --------------------------

     Under the criteria set forth in Statement of Financial Accounting Standards
No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased or
Otherwise Marketed", capitalization of software development costs begins upon
the establishment of technological feasibility of the product and ends when the
product is ready for general release.  The establishment of technological
feasibility and the ongoing assessment of the recoverability of these costs
require considerable judgment by management with respect to certain external
factors, including, but not limited to, anticipated future gross product
revenues, estimated economic life and changes in software and hardware
technology.  Amounts that could have been capitalized under this statement after
consideration of the above factors were immaterial and, therefore, no software
development costs have been capitalized by the Company to date.

     Reclassifications
     -----------------

     Certain 1993 amounts have been reclassified to conform to the 1994
presentation.

(3)  RELATED PARTY TRANSACTIONS
     --------------------------

     On June 12, 1995, the Company received $3,000,000 from Eli Lilly and
Company (a stockholder) as a bridge loan.  The note bears interest at a rate of
10% per annum and matures on July 1, 1996.  An additional $1,000,000 was
received from Eli Lilly on July 27, 1995 with maturity of July 1, 1996, bearing
interest at 10% per annum and an additional $1,000,000 was received from Eli
Lilly on August 28, 1995 with maturity of July 1, 1996, bearing interest at 10%
per annum (see Note 5).  The loans from Eli Lilly are subordinated to IMS's
other indebtedness and are secured by a pledge of most of the assets of IMS.
The loans become immediately due and payable if IMS breaches the Merger
Agreement (see Note 11), subject to certain rights of IMS to cure such breach.

     In January 1995, the Company's chairman transitioned from his role in day-
to-day management to that of a board member only.  The Company will continue his
compensation at its present rate through December 31, 1995.  These and other
related costs are included in payables to related parties in the accompanying
consolidated 1994 balance sheet.

     The Company issued warrants to purchase 79,302 shares of common stock at $4
per share to its chairman in January of 1994.  The Company owed amounts to its
chairman at 

                                      F-13

 
December 31, 1993 totaling $166,938. This amount was paid in 1994. Such amount
was noninterest bearing and due on demand.

     During 1993, the Company's board of directors established a management
committee comprised of five senior vice presidents in charge of the Company's
five functional areas.  As part of their 1993 compensation, the members of the
management committee received fully vested options to purchase 25,000 shares of
common stock each at $4.00 per share.  As part of their 1994 compensation, the
                      ----                                                    
members of the management committee received options to purchase 100,000 shares
of common stock each at $4.00 per share.
                         ----           

     In the normal course of business, the Company's networks incur costs
payable to the Company's joint venture partners.  At December 31, 1994, such
payables totaled approximately $707,000, and were included in payables to
related parties in the accompanying consolidated balance sheets.

     During 1994 and 1993, the Company reimbursed a director of the Company for
approximately $61,000 and $125,000, respectively, of legal fees paid on behalf
of the Company under an indemnification agreement.

     During 1994, the Company sold $177,500 of software and equipment to a
company owned by a director of the Company, who in turn sold these items to a
hospital.  The Company recorded this revenue upon the network becoming
operational and all significant obligations of the Company being fulfilled.

     During 1993, an affiliate of a shareholder loaned the Company $250,000
under the terms of a 9% promissory note.  This amount was repaid in 1994.

     In 1992, a limited partner in IMS-Network of Colorado, Ltd. loaned the
Company $165,000 pursuant to two $82,500 promissory notes, secured by a
collateral assignment of payments due under a network license agreement.  During
1993, the Company repaid one of these promissory notes.  The remaining note was
repaid in 1994.

     During 1993, a director of the Company advanced $250,000 to the Company to
meet short-term cash requirements.  Also, three directors advanced $75,000 each
($225,000 total) to the Company to meet short-term cash requirements.  These
advances were interest bearing (short-term bank rates) and were secured by
assignments of cash flows.  These advances were repaid prior to December 31,
1993.

     During 1992, a senior vice president of the Company funded a $200,000
security bond for the Company related to the litigation described in Note 6.
This same officer also sold certain of his common stock in the Company to an
unrelated party and loaned the proceeds of $90,000 to the Company.  These loans
were repaid by the Company in 1993.

     In consideration for certain loans and/or personal guarantees related to
the Company's borrowings, as discussed above, from a bank and other obligations,
the Company issued warrants to purchase 28,000 and 191,800 shares of common
stock to directors and a shareholder during 1994 and 1993, respectively, at
$3.50-$5.00 per share (see Note 8).

                                      F-14

 
(4)  INCOME TAXES
     ------------

     The Company adopted SFAS 109 as of January 1, 1993.  This change in
accounting principle had no cumulative effect on the Company's financial
position or results of operations as of January 1, 1993.

     The net deferred tax assets and liabilities as of December 31, 1994, are
comprised of the following:

                                              ===========


     The Company has determined that $4,430,000 of net deferred tax assets as of
December 31, 1994 do not satisfy the realization criteria set forth in SFAS 109.
Recognition of these assets requires future taxable income, the attainment of
which is uncertain.

Accordingly, a valuation allowance has been recorded to offset the entire
deferred tax asset.

     At December 31, 1994, the Company has tax credit carryforwards available to
offset future taxable income of approximately $67,600 which expire through 2006.
In addition, the Company has net operating loss carryforwards of approximately
$11,300,000 which expire through 2009.

                                      F-15

 
     The net operating loss and credit amounts are subject to examination by the
tax authorities.  The Internal Revenue Code contains provisions which may limit
the net operating loss and tax credit carryforwards available to be used in any
given year upon the occurrence of certain events, including significant changes
in ownership.

     At December 31, 1994, the Company had no current federal or state income
taxes payable.

     The difference between the 1993 and 1994 losses reported for financial
reporting and the losses reported for income tax purposes was primarily the
result of the treatment of contributions from joint venturers as capital
contributions for financial reporting purposes and as taxable income for tax
reporting purposes, accelerated depreciation for tax purposes, and certain
accruals not currently deductible for tax reporting purposes.

(6)  COMMITMENTS AND CONTINGENCIES
     -----------------------------

  Litigation
  ----------

  The Company was involved, beginning in January 1992, in a dispute with
NewHealth Group, Inc. ("NHG"), the former 49% owner of IMS-Net of Northern
California, Inc. ("Norcal") and the former manager of Norcal and IMS-Net of
Sacramento, Inc. ("Sacto"), its 100% owned subsidiary.

  During 1994 and early 1995, all of the litigation surrounding this dispute was
terminated in favor of the Company.  Additionally, the Company won monetary and
punitive judgments against NHG and its officers and Norcal has recovered and
retired the outstanding 49% minority interest in Norcal, formerly owned by NHG,
so that the Company owns 100% of Norcal as of December 31, 1994.  As the Company
is uncertain as to the ultimate collectibility of the judgments, the monetary
and punitive judgments will be recognized for financial reporting purposes when
and if the judgments are collected.  No value was recorded for recovery and
retirement of the 49% minority interest.

  During 1993, 1994 and the first six months of 1995, the Company expensed
approximately $1,658,000, $785,000 and 53,000, respectively, in legal costs
relating to this litigation.

  Conversion Obligation
  ---------------------

  Under the terms of a joint venture agreement between the Company and a
corporation, the corporation, as limited partner in the joint venture, may elect
to exchange all or increments of 20% of its rights to profits allocations in the
joint venture for shares of the Company's common stock.  The number of shares is
to be determined by dividing $3.5 million by the market price of IMS common
stock at the time of exchange.  Such option is available to the corporation for
three years and 120 days after commencement of a public offering of the common
stock of the Company.

  Obligation to Fund Joint Ventures
  ---------------------------------

  The Company has agreed to fund operating cash shortfalls of certain networks
under the terms of certain joint venture and network services agreements.

   Lease Obligations
   -----------------

   The Company has entered into various noncancelable operating leases for
office space.  Total rental expense related to these lease agreements in 1993
and 1994 was $654,331 and $1,035,111, respectively.

                                      F-18

 
   Future minimum lease payments under noncancelable operating lease agreements
as of December 31, 1994 are as follows:



 
                        
          1995             $  990,198
          1996                880,812
          1997                671,552
          1998                275,835
          1999                131,280
          Thereafter            4,237
                           ----------
               
            Total          $2,953,914
                           ==========


    Subsequent to December 31, 1994, the Company entered into various operating
leases for office space.  Future minimum lease payments related to these leases
total approximately $704,000 and have been included in the above table.

    Letters of Credit
    -----------------

    At December 31, 1994, the Company had letters of credit outstanding totaling
approximately $213,000 collateralizing certain capital lease and tenant
finishings.  The letters of credit expire at various dates through 1999.

(7) PARTNERS' INVESTMENT IN LIMITED PARTNERSHIP
    -------------------------------------------

    During 1992, the Company, through its wholly-owned subsidiary IMS-Net of
Colorado, Inc. ("IMS-Colorado"), obtained a 1% general partner interest in IMS-
Network of Colorado, Ltd. (the "Partnership"), a Colorado limited partnership.
The Partnership was formed for the purpose of obtaining business and technology
licenses from the Company to operate a medical communication network (the
"Network") in Colorado and to sublicense such rights to IMS-Colorado.  IMS-
Colorado operates the Network and paid license fees to the Partnership based on
gross revenues received from the Network.

    During 1993 and 1994, the Partnership distributed $143,559 and $209,219,
respectively, to the limited partners representing 99% of the royalties earned
by the Partnership.  The accounts of the Partnership were consolidated in the
accompanying 1993 financial statements as IMS-Colorado was the general partner.
All intercompany transactions and accounts were eliminated in the accompanying
consolidated 1993 financial statements.  As of December 31, 1994, the
Partnership was dissolved as discussed below.

    Due to the Company's various obligations to the limited partners, amounts
received from the limited partners ($1,820,000 at December 31, 1993) were
excluded from stockholders' equity in 1993.  Such amounts were converted and
reclassified to common stock in 1994 as discussed below.

    On December 9, 1994, the Company made an exchange offering (the "Exchange")
to each limited partner of the Partnership and each holder of IMS-Colorado
preferred stock.  

                                      F-19

 
Pursuant to the Exchange, each Partnership unit and each preferred share of IMS-
Colorado was surrendered to the Company in exchange for 4,000 shares of common
stock of the Company and also received one nontransferable common stock purchase
warrant entitling the holder to purchase up to 2,000 and 4,000 additional shares
of common stock at $5 per share, respectively. Each warrant is exercisable in
accordance with its terms for a period of three years through December 1997.

     Each limited partner and shareholder accepted the Exchange and 324,000 and
40,000 shares of common stock and warrants to purchase 162,000 and 40,000 shares
of common stock were issued to the holders of the Partnership units and IMS-
Colorado preferred stock, respectively, as set forth above, and the Partnership
was dissolved as of December 31, 1994.

(8)  STOCKHOLDERS' EQUITY
     --------------------

     Series B Preferred Stock
     ------------------------

     Each share of Series B voting preferred stock ("Series B") is convertible
at a price per share of $1.50, at the option of the holder into common stock.
Such conversion is automatic at the consummation of an initial public offering
by the Company. The Series B is entitled to receive cumulative dividends of 10%
of the liquidation value ($.10 per share) on an annual basis. Accumulated
undeclared and unpaid dividends were $1,300,000 and $1,400,000 at December 31,
1994 and June 30, 1995, respectively. Such cumulative dividends have not been
accrued as the Company has an accumulated deficit and, therefore, is unable to
declare or pay dividends. As dividends have not been declared as of June 30,
1995 no accrual has been made in the accompanying financial statements. In the
event of liquidation, holders of Series B will be entitled to a liquidation
preference of $1.00 per share plus accrued and unpaid dividends. The Company was
not in compliance with certain reporting covenants of the Series B Preferred
Stock Agreement at December 31, 1994.

     Series C Preferred Stock
     ------------------------

     Under terms of a Subscription Agreement dated December 30, 1993, a Series C
Preferred Stock Purchase Agreement dated January 6, 1994, and a Network
Sponsorship and Participation Agreement dated November 17, 1993, a corporation
purchased 1,250,000 shares of IMS's Series C convertible preferred stock
("Series C") at $4 per share for a total of $5 million on January 6, 1994.  On
July 12, 1994, this corporation also purchased an additional 1,000,000 shares of
Series C at $5 per share by applying as partial payment the $1 million in
national network sponsorship and access fees paid in 1993.  The Series C has
liquidation preferences over the Company's common stock but is subordinate to
holders of Series B and is convertible on a 1-to-1 basis to the Company's common
stock at the purchaser's option.  Such conversion is automatic at the
consummation of an initial public offering above certain thresholds.  Upon the
occurrence of certain circumstances, the Series C preferred stock has
noncumulative voting rights equal to shares of the Company's common stock and is
not redeemable.

     The Company also issued warrants to the purchasing corporation in
connection with its investment in the Company's Series C and in conjunction with
the Network Sponsorship and Participation Agreement. In conjunction with the
first and second tranches of Series C as discussed above, the Company issued
warrants to purchase 750,000 and 500,000 shares, respectively, of Series C. In
1994, this corporation exercised warrants to purchase 375,000 shares of Series C
for $1,875,000. Subsequent to yearend, this corporation exercised warrants to
purchase an additional 375,000 shares of Series C for $1,875,000. The additional
500,000

                                      F-20

 
warrants are exercisable during the two-year period after grant at $6 and $7 per
share during the first and second years, respectively.

   In connection with the investment in the Company, the Company granted the
purchasing corporation a right of first offer on IMS shares under certain
circumstances.  If the Company receives an offer from a potential investor, it
is obligated, except with respect to certain investors, to offer shares to the
purchasing corporation under substantially the same terms as those negotiated
with the potential investor.  During November 1994, the purchasing corporation
was acquired by Eli Lilly and Company who may or may not have succeeded to these
rights.

   Under terms of a Letter of Intent and Option Agreement dated November 10,
1993, another corporation has paid the Company $600,000 which is reflected as
other deferred credits in the accompanying consolidated balance sheets.  The
option agreement was terminated in January 1995.  If the corporation does not
make such an investment, the $600,000 will be applied to payments due under the
corporation's Communications Services Agreement with the Company.

   Stock Warrants

   Stock warrants have been issued to certain investors.  Common stock warrant
activity during 1993 and 1994, and the first six months in 1995 is as follows:

                                      F-21

 
   The warrants are fully vested at date of grant and are exercisable at varying
times through July 1998.

   Series C Warrants
   -----------------

   In 1994, the Company also issued Series C warrants, as discussed above, of
which warrants to purchase 1,250,000 shares of Series C at prices ranging from
$5.00 - $7.00 were granted and 375,000 were exercised at $5.00 per share.
Subsequent to yearend, holder of such warrants exercised warrants to purchase an
additional 375,000 shares of Series C for $1,875,000.

   Common Stock Option Plans
   -------------------------

   The Company has adopted its 1989 Stock Option Plan (the "1989 Plan")
providing for the grant of options to purchase a maximum of 1,600,000 shares of
common stock to key employees.  Under the terms of the 1989 Plan, the option
exercise price is to be no less than the fair market value of IMS' stock on the
date of grant.  Options are exercisable three months following the date of grant
and up to 10 years from such date.  If employment is terminated for any reason,
the holder of the options has three months in which to exercise before
cancellation unless written approval of the compensation committee extends such
exercise to 12 months.

   Stock option activity during 1993 and 1994, and the first six months in 1995
for the 1986 Plan is as follows:

   Stock options from the 1989 Plan vest ratably at times ranging from one to
three years and are exercisable at various times through 1999.  As of December
31, 1994, 1,115,174 options were exercisable.

   On April 22, 1994, the shareholders of IMS approved the 1994 Employee Stock
Option Plan (the "1994 Plan").  The 1994 Plan may grant incentive and
nonqualified stock options; however, in 1994, only nonqualified stock options
were granted.  Under the 1994 Plan, the Company is authorized to grant options
to purchase a maximum of 400,000 shares of common stock to key employees.  As of
December 31, 1994, the Company had granted more options than authorized in the
1994 Plan.  Subsequent to yearend, the Company's board of directors approved
increasing the number of authorized shares by 438,600 and intends to seek
shareholders' approval at the next Shareholders' meeting.  In management's
opinion, this increase will be approved.  Such options are exercisable six
months following the date of grant.  All other terms are similar to the 1989
Plan.

   Stock option activity since 1994 for the 1994 Plan is as follows:

   Stock options from the 1994 Plan vest ratably over three years and are
exercisable at various times through 2004.  As of December 31, 1994, 25,401
options were exercisable.  Upon the Merger becoming effective, all options
become fully vested.

   Subscriptions Receivable
   ------------------------

   Stock subscriptions and joint venturers' contributions receivable consist of
amounts to be received for sale of common stock and formation of joint ventures.
The amounts shown as current assets were collected subsequent to yearend.

(9)  401(k) PLAN
     -----------

   In 1993, the Company adopted a 401(k) plan for its employees.  Under this
plan, the Company may contribute to the plan at its discretion.  The total
amount contributed by the Company to the plan during the years ended December
31, 1993 and 1994 was $50,067 and $79,353, respectively.

(10) ACCOUNTS RECEIVABLE SALES
     -------------------------

     Subsequent to December 31, 1994, the Company sold without recourse its
rights to the remaining payments due under certain network license agreements
for a price equal to the present value of the remaining noncancelable license
fee payments. Proceeds from the sales were approximately $2.8 million.

(11) MERGER WITH ELI LILLY AND COMPANY (UNAUDITED)
     ---------------------------------------------

     As noted earlier, the Company signed an Agreement and Plan of Merger (the
"Plan") with Lilly on August 2, 1995.  The following discussion outlines the
general terms and consideration of the Plan and the impact of the Plan on the
Company's capital structure.

     If the Merger is approved by the Company's shareholders, each share of
common stock will be converted into the right to receive $8.00 in cash or one
share of new Series D preferred stock ("Preferred D"). Each share of Series B
preferred stock will be converted into the right to receive $5.33 in cash plus
any accrued unpaid dividends as of the closing date or two-thirds of a Preferred
D share plus any accrued unpaid dividends on the original Series B as of the
closing date, or such Series B shareholders may elect to retain the Series B
shares with the amended terms and conditions set forth in the Plan and exhibits
thereto.

     Each Series C preferred share will convert to one share of common stock.

     Option and warrant holders have the right either to (i) receive $8.00 in
cash per share into which each such option or warrant was exercisable as of the
closing date net of the exercise price, or (ii) retain the right to purchase one
share of Preferred D stock for each share of common stock into which such option
or warrant was exercisable as of the closing date. Company option holders have
the further option to receive fully vested options to acquire shares of common
stock of Lilly under the 1994 Lilly Stock Plan.

     All new Preferred D shareholders will have the option to enter into a
Put/Call Agreement with Lilly whereby each holder of Preferred D shares would
have the right to put their shares to Lilly during two put periods beginning one
year after the closing date and 30 months after the closing date.  Pursuant to
the Put/Call Agreements, Lilly would have the right to call the Preferred D
stock, which right could be exercised any time after three years from the
closing date.  The put and call purchase price is $8.00 per share plus any
unpaid dividends accrued prior to the purchase date.

     The Preferred D shares also carry mandatory redemption features.  For the
period of 30 days after the fifth anniversary of the effective date of the
Merger, the holders may demand redemption of their shares for $8.00 per share
plus all accrued and unpaid dividends.  The Company has the option, beginning on
the fifth anniversary of the Merger effective date, to redeem any or all shares
of Preferred D at a redemption price of $8.00 per share plus all accrued and
unpaid dividends.

     Rights"):

               6.1  Right to Convert.  Each share of Series B Preferred Stock
                    ----------------

     or (ii) two-thirds of a share of the corporation's Series D Preferred
     Stock, par value $.O1 per share (the "Series D Preferred Stock").

     Preferred Stock shall be entitled to convert the same into cash or shares
     of Series D Preferred Stock, such holder shall surrender the certificate or
     certificates therefor, duly endorsed, at the office of the corporation or
     of any transfer agent for the Series B Preferred Stock, and shall give
     written notice to the corporation at such office that such holder elects to
     convert the same into cash or Series D Preferred Stock.  The corporation
     shall, as soon as practicable thereafter, either pay the required cash to
     the holder of Series B Preferred Stock or issue and deliver at such office
     to such holder of Series B Preferred Stock a certificate or certificates
     for the number of shares of Series D Preferred Stock to which such holder
     shall be entitled as aforesaid.  Such payment or conversion shall be deemed
     to have been made immediately prior to the close of business on the date of
     such surrender of the shares of Series B Preferred Stock to be cashed out
     or converted, and, if the holder elects to acquire Series D Preferred
     Stock, the person or persons entitled to receive the shares of Series D
     Preferred Stock issuable upon such conversion shall be treated for all
     purposes as the record holder or holders of such shares of Series D

     Preferred Stock shall be issued upon conversion of the Series B Preferred
     Stock.  Fractional shares shall not be issued; and, in lieu of fractional
     shares to which the holder would otherwise be entitled, the corporation
     shall pay cash equal to said fraction multiplied by 150% of the Liquidation
     Value of a share of the Series B Preferred Stock.

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

               6.4.1     The corporation shall not issue any shares of Series D
     Preferred Stock other than those shares issued in connection with the
     merger of Trans-IMS Corporation into the corporation or any shares
     subsequently issued upon conversion of Series B Preferred Stock as provided
     in this Article Fourth or upon exercise of the Company Options and the
     Company Warrants contemplated by the Articles of Merger for such merger.

               6.4.2     The number of shares of Series D Preferred Stock
     outstanding at any time after the date hereof may not be increased by a
     stock dividend payable in shares of Series D Preferred Stock or by a
     subdivision or split-up of shares of Series D Preferred Stock.

               6.4.3     The number of shares of Series D Preferred Stock
     outstanding at any time after the date hereof may not be decreased by a

               6.4.4     If at any time after the date hereof there occurs any
     capital reorganization, or any reclassification of the capital stock of the
     corporation (other than a change in par value or as a result of a stock
     dividend or subdivision, split-up or combination of shares), or the
     consolidation or merger of the corporation with or into another person
     (other than a consolidation or merger in which the corporation is the
     continuing entity and which does not result in any change in the Series D
     Preferred Stock), or the sale or other disposition of all or substantially
     all of the properties and assets of the corporation as an entity to any
     other person, the shares of Series B Preferred Stock shall, after such
     reorganization, reclassification, consolidation, merger, sale or other
     disposition, be convertible into the kind and number of shares of stock or
     other securities or property of the corporation or of the entity resulting
     from such consolidation or surviving such merger or to which such
     properties and assets shall have been sold or otherwise disposed to which
     such holder would have been entitled if, immediately prior to such
     reorganization, reclassification, consolidation, merger, sale or other
     disposition, such holder had converted his shares of Series B Preferred
     Stock into Series D Preferred Stock.  The provisions of this Section 6.4.4
     shall similarly apply to successive reorganizations, reclassifications,
     consolidations, mergers, sales or other dispositions.

          7.  No Impairment.  The corporation shall not, by amendment of its
              -------------                                                 
     Articles of Incorporation or through any

                                       5

 
     reorganization, transfer of assets, consolidation, merger, dissolution,
     issue or sale of securities, or any other voluntary action, avoid or seek
     to avoid the observance or performance of any of the terms to be observed
     or performed hereunder by the corporation, but shall at all times in good
     faith assist in the carrying out of all the provisions of this Section 7
     and in the taking of all such action as may be necessary or appropriate in
     order to protect the Conversion Rights of the holders of Series B Preferred
     Stock against impairment.

          8.  Notices of Record Date.  In the event of any taking by the
              ----------------------                                    
     corporation of a record of the holders of any class of securities for the
     purpose of determining the holders thereof who are entitled to receive any
     dividend (other than a cash dividend) or other distribution, the
     corporation shall mail to each holder of Series B Preferred Stock, at least
     twenty (20) days prior to the date specified herein, a notice specifying
     the date on which any such record is to be taken for the purpose of such
     dividend or distribution.

          9.  Reservation of Stock Issuable Upon Conversion.  The corporation
              ---------------------------------------------                  
     shall at all times reserve and keep available out of its authorized but
     unissued shares of Series D Preferred Stock solely for the purpose of
     effecting the conversion of the shares of Series B Preferred Stock such
     number of its shares of Series D Preferred Stock as shall from time to time
     be sufficient to effect the conversion of all outstanding shares of the
     Series B Preferred Stock; and, if at any time the number of authorized but
     unissued shares of Series D Preferred Stock shall not be sufficient to
     effect the conversion of all then outstanding shares of the Series B
     Preferred Stock, the corporation shall take such corporate action as may,
     in the opinion of its counsel, be necessary to increase its authorized but
     unissued shares of Series D Preferred Stock to such number of shares as
     shall be sufficient for such purpose.

          10.  Notices.  Any notice required to be given to the holder of shares
               -------                                                          
     of Series B Preferred Stock shall be deemed given if deposited in the
     United States mail, postage prepaid, and addressed to each holder of record
     at his address appearing on the books of the corporation.

          11.  Protective Provisions.  So long as any of the Series B Preferred
               ---------------------                                           
     Stock shall be outstanding, the corporation shall not, without first
     obtaining the approval (by vote or written consent, as provided by law) of
     the holders of at least fifty-one percent (51%) of the outstanding shares
     of Series B Preferred Stock, alter or

                                       6

 
     change the rights, preferences or privileges of the Series B Preferred
     Stock.

          12.  No Reissuance of Preferred Stock.  No share or shares of Series B
               --------------------------------                                 
     Preferred Stock acquired by the corporation by reason of redemption,
     purchase, conversion or otherwise shall be reissued, and all such shares
     shall be cancelled, retired and eliminated from the shares that the
     corporation shall be authorized to issue.

          13.  Amendment and Waiver.  Amendments, modifications or waivers of
               --------------------                                          
     any of the terms hereof will be binding and effective if the prior written
     consent of holders of at least 51% of the Series B Preferred Stock
     outstanding at the time such action is taken is obtained; provided that no
     such action will change (a) the rate at which or the manner in which
     dividends on the Series B Preferred Stock accrue or the times at which such
     dividends become payable, unless the prior written consent of the holders
     of at least 91% of the Series B Preferred Stock then outstanding is
     obtained, (b) the Conversion Rights of the Series B Preferred Stock or the
     number of shares or class of stock into which the Series B Preferred Stock
     is convertible, unless the prior written consent of the holders of at least
     91% of the Series B Preferred Stock then outstanding is obtained or (c) the
     percentage required to approve any change described in clauses (a) and (b)
     above, unless the prior written consent of the holders of at least 91% of
     the Series B Preferred Stock then outstanding is obtained.

          FIFTH:    The corporation is authorized and empowered to issue shares
          -----                                                                
of Series D Preferred Stock, having the following preferences, limitations and
relative rights:

          1.  Designation and Amount.  The shares of such series shall be
              ----------------------                                     
     designated as the Series D Preferred Stock (the "Series D Preferred Stock")
     and the number of shares initially constituting such series shall be
     12,000,000, which number may be decreased (but not increased) by the Board
     of Directors without a vote of the shareholders; provided, however, that
     such number may not be decreased below the sum of the number of then
     currently outstanding shares of Series D Preferred Stock and the number of
     shares of Series D Preferred Stock reserved for issuance upon exercise of
     then currently outstanding options and warrants of the corporation.  Shares
     of Series D Preferred Stock shall have a preference over shares of the
     corporation's common stock, without par value (the "Common Stock") upon
     liquidation, dissolution or winding up of the corporation.

                                       7

 
          2. Dividends.  Holders of the outstanding shares of Series D Preferred
             ---------                                                          
     Stock shall be entitled to receive, if, as and when declared by the Board
     of Directors out of funds legally available therefor, cumulative cash
     dividends at an annual rate of $0.62 per share, in preference to and in
     priority over any dividends with respect to the Common Stock.  Dividends on
     the outstanding shares of Series D Preferred Stock shall begin to accrue
     and be cumulative (regardless of whether such dividends have been declared
     by the Board of Directors) beginning on the date of issuance, and shall be
     payable annually in arrears each December 31 until and unless redeemed by
     the corporation.

          3.  Voting Rights.  (a)  Outstanding shares of Series D Preferred
              -------------                                                
     Stock shall have no voting rights other than such voting rights as shall be
     required by the Colorado Business Corporation Act or as otherwise provided
     below in this Section 3.

          (b)  Whenever, at any time or times, dividends payable on any share or
     shares of Series D Preferred Stock shall be in arrears in an amount equal
     to at least two full annual dividends (whether or not declared and whether
     or not consecutive and whether or not funds are legally available for such
     dividends), the holders of record of the outstanding Series D Preferred
     Stock shall have the exclusive right, voting separately as a single class,
     to elect one director of the corporation at a special meeting of
     shareholders of the corporation or at the corporation's next annual meeting
     of shareholders, and at each subsequent annual meeting of shareholders, as
     provided below.  At elections for such director, the holders of shares of
     Series D Preferred Stock shall be entitled to cast one vote for each share
     held.

          (c)  Upon a failure by the corporation to redeem any shares of Series
     D Preferred Stock pursuant to any demand duly made pursuant to Section 4(a)
     below (whether or not such failure results from the corporation's failure
     to have sufficient funds legally available for such redemption), then the
     holders of record of the Series D Preferred Stock shall have, as their sole
     remedy in respect of such failure, the exclusive right, voting separately
     as a single class, to elect the smallest number of directors of the
     corporation that shall constitute a majority of the authorized number of
     members of the Board of Directors (including new directorships created
     pursuant to Section 4(d) below) at a special meeting of shareholders of the
     corporation or at the corporation's next annual meeting of shareholders,
     and at each subsequent annual meeting of shareholders, as provided below.
     At elections for such directors, the

                                       8

 
     holders of shares of Series D Preferred Stock shall be entitled to cast one
     vote for each share held.  If such holders exercise such right to elect a
     majority of the directors, then following the election of such directors
     and during the period in which a majority of the directors are persons
     elected by such holders (or the successors of such directors), the
     corporation shall be required to redeem all of the shares of Series D
     Preferred Stock for which redemption was duly demanded pursuant to Section
     4(a) below as soon as practicable if and to the extent that funds are
     legally available therefor.  Any such redemption shall be made in
     accordance with the procedures set forth in Section 4(c) below as if it
     were a redemption pursuant to Section 4(b) but subject to being given the
     priority set forth in the proviso to Section 4(c)(i) below.  During any
     period while the right to elect directors pursuant to this Section 3(c) is
     vested, the director, if any, elected pursuant to Section 3(b) and then in
     office shall be deemed to be one of the directors elected pursuant to this
     Section 3(c).

          (d)  Upon the vesting of such right of the holders of the Series D
     Preferred Stock to elect any directors pursuant to Section 3(b) or (c)
     above, the maximum authorized number of members of the Board of Directors
     shall be automatically increased, (i) in case of a right pursuant to
     Section 3(b) above, by one and, (ii) in the case of a right pursuant to
     Section 3(c) above, by the maximum number of members of the Board of
     Directors immediately theretofore authorized (but excluding from such
     maximum number the member, if any, authorized pursuant to Section 3(b)),
     plus one, and the vacancy or vacancies so created shall be filled by vote
     of the holders of the outstanding Series D Preferred Stock as hereinafter
     set forth.  A special meeting of the shareholders of the corporation then
     entitled to vote shall be called by the Chairman of the Board of Directors
     or the President or the Secretary of the corporation, if requested in
     writing by the holders of record of not less than 25% of the Series D
     Preferred Stock then outstanding.  At such special meeting, or, if such
     special meeting shall not have been called, then at the next annual meeting
     of shareholders of the corporation, the holders of the Series D Preferred
     Stock shall elect, voting as above provided, a director or directors to
     fill the aforesaid vacancy or vacancies created by the automatic increase
     in the number of members of the Board of Directors.  At any and all such
     meetings for such election, the holders of a majority of the outstanding
     shares of the Series D Preferred Stock shall be necessary to constitute a
     quorum for such election, whether present in person or by proxy, and such
     director or directors

                                       9

 
     shall be elected by the vote of at least a plurality of shares held by such
     shareholders present or represented at the meeting.  Any director elected
     by holders of the Series D Preferred Stock pursuant to this Section may be
     removed at any annual or special meeting, by vote of a majority of the
     outstanding shares of the Series D Preferred Stock, with or without cause.
     In case a director so elected shall vacate such position, such vacancy may
     be filled by unanimous agreement of the remaining directors so elected, or
     their successors then in office, if any, or may be filled in the same
     manner as is provided above for the initial election of a director by the
     holders of the Series D Preferred Stock.

          (e)  The right of the holders of the Series D Preferred Stock, voting
     separately as a class, to elect one director of the Board of Directors
     pursuant to Section 3(b) above shall continue until, and only until, such
     time as all arrears in dividends (whether or not declared) on the Series D
     Preferred Stock shall have been paid or declared and set apart for payment,
     at which time such right shall terminate, except as expressly provided by
     law, subject to revesting in the event of each and every subsequent default
     of the character above-mentioned.  The right of such holders, voting
     separately as a class, to elect directors pursuant to Section 3(c) above
     shall continue until, and only until, such time as the corporation has
     redeemed all of the shares of Series D Preferred Stock for which redemption
     was duly demanded pursuant to Section 3(c) above, at which time such right
     shall terminate, except as expressly provided by law.  Upon any termination
     of the right of the holders of the Series D Preferred Stock as a class to
     vote for a director or directors as herein provided, the term of office of
     any such director or directors then in office shall terminate immediately.
     Whenever the term of office of any director elected by the holders of the
     Series D Preferred Stock pursuant to this Section shall terminate and the
     special voting powers vested in the holders of the Series D Preferred Stock
     pursuant to this Section shall have expired, the maximum number of members
     of the Board of Directors shall be such as may be provided for in the By-
     Laws of the corporation irrespective of any increase made pursuant to the
     provisions of this Section.

          4.  Redemption.  (a)  At the Option of Holders.  During, and only
              ----------        ------------------------                   
     during the period of 30 days beginning on the fifth anniversary of the
     effective date of the merger of Trans-IMS Corporation into the corporation,
     any one or more holders of shares of Series D Preferred Stock, at the
     option of such holders, may demand that the corporation redeem any or all
     of their shares of Series D Preferred Stock at a redemption price of $8.00
     per

                                       10

 
     share, plus an amount equal to all accrued and unpaid dividends thereon
     (whether or not declared) to and including the date of redemption.  Such
     demand shall be made by delivering to the corporation at its principal
     executive offices a written demand during the aforesaid 30-day period.
     Such demand shall specify the number of shares to be redeemed and shall be
     irrevocable, except with the consent of the corporation.  Following receipt
     of any such demand, the corporation may, at its option, choose to redeem,
     or not to redeem, shares in accordance with such demand and the provisions
     of this Section 4.  If shares are to  be so redeemed, the corporation shall
     fix a redemption date that shall be not later than 90 days after such fifth
     anniversary.  The corporation shall give notice of redemption by first
     class mail, postage prepaid, mailed not less than 20 days prior to the date
     fixed for redemption to the holders whose shares are to be redeemed at
     their respective addresses appearing on the stock books of the corporation.
     Notice so mailed shall be conclusively presumed to have been duly given
     whether or not actually received.  Such notice shall state:  (i) the date
     fixed for redemption; (ii) the redemption price; (iii) the number of shares
     of Series D Preferred Stock to be redeemed and if less than all the shares
     held by such holder are to be redeemed, the number of shares to be so
     redeemed from such holder; (iv) the place where certificates for such
     shares are to be surrendered for payment of the redemption price; and (v)
     that after the close of business on such date fixed for redemption the
     shares to be so redeemed shall not accrue dividends.  If the corporation
     does not redeem all of the shares of Series D Preferred Stock for which
     redemption has been duly demanded pursuant to this Section, the sole remedy
     of the holders of such shares in respect of such failure to redeem shall be
     the exercise of the voting rights conferred by Section 3(c) above.  For the
     purposes of Section 3 above, the corporation shall be considered to have
     redeemed any shares for which redemption has been duly demanded if such
     shares are thereafter purchased by the corporation or any person or entity
     that then owns, directly or indirectly, at least 50% of the corporation's
     then outstanding Common Stock.

          (b)  At the Option of the Corporation.  On and after the fifth
               --------------------------------                         
     anniversary of the effective date of the merger of Trans-IMS Corporation
     into the corporation, the corporation, at its option, may redeem any or all
     shares of Series D Preferred Stock at a redemption price of $8.00 per
     share, plus an amount equal to all accrued and unpaid dividends thereon
     (whether or not declared) to and including the date of redemption.

                                       11

 
          (c)  Redemption Procedures.  (i)  If, pursuant to Section 4(a), the
               ---------------------                                         
     corporation will redeem less than all of the shares for which demands for
     redemption were duly made, or if less than all of the outstanding shares of
     Series D Preferred Stock are to be redeemed pursuant to Section 4(b), the
     shares to be redeemed shall be selected pro rata (subject to rounding to
     avoid fractional shares) as nearly as practicable or by lot, or by such
     other method as the Board of Directors may determine to be equitable;
     provided, however, that if the corporation is proposing to redeem shares
     pursuant to Section 4(b) and any shares for which demands for redemption
     were duly made pursuant to Section 4(a) have not been redeemed, then
     priority shall be given to the redemption of such shares for which such
     demands were duly made.

          (ii)  Notice of any redemption pursuant to Section 4(b) shall be given
     by first class mail, postage prepaid, mailed not less than 30 nor more than
     60 days prior to the date fixed for redemption to the holders of record of
     the Series D Preferred Stock to be redeemed at their respective addresses
     appearing on the stock books of the corporation.  The Board of Directors of
     the corporation shall fix a record date for determining holders of record
     who are entitled to receive notice of any redemption, not more than 10 days
     prior to the mailing of such notice.  Notice so mailed shall be
     conclusively presumed to have been duly given whether or not actually
     received.  Such notice shall state:  (i) the date fixed for redemption;
     (ii) the redemption price; (iii) the number of shares of Series D Preferred
     Stock to be redeemed and if less than all the shares held by such holder
     are to be redeemed, the number of shares to be so redeemed from such
     holder; (iv) the place where certificates for such shares are to be
     surrendered for payment of the redemption price; and (v) that after the
     close of business on such date fixed for redemption the shares to be so
     redeemed shall not accrue dividends.

          (iii)  Upon surrender in accordance with the notice of redemption
     referred to in Section 4(a) or 4(c)(ii), the certificate for any shares of
     Series D Preferred Stock so redeemed (duly endorsed or accompanied by
     appropriate instruments of transfer, if so required by the corporation in
     such notice), the holders of record of such shares shall be entitled to
     receive the redemption price, without interest.  In case fewer than all the
     shares represented by any such certificate are redeemed, a new certificate
     shall be issued representing the unredeemed shares without cost to the
     holder thereof.

          (iv)  Notice of redemption having been mailed as provided in Section
     4(a) or 4(c)(ii), from and after the

                                       12

 
     redemption date (unless default shall be made by the corporation in
     providing money for the payment of the redemption price) dividends on the
     shares of the Series D Preferred Stock called for redemption shall cease to
     accrue, and said shares shall no longer be deemed to be outstanding, and
     all rights of the holders thereof as stockholders of the corporation
     (except the right to receive from the corporation the redemption price)
     shall cease.

          5.  No Preemptive Rights.  No holder of a share or shares of Series D
              --------------------                                             
     Preferred Stock shall, because of such holder's ownership of such stock,
     have a preemptive right to purchase, subscribe for or take any part of any
     capital stock of the corporation nor shall any such holder have a
     preemptive right to purchase, subscribe for or take any part of notes,
     debentures, bonds or any other securities of the corporation, including,
     but not limited to, securities convertible into or carrying options or
     warrants to purchase capital stock of the corporation.
 
          6.  Liquidation Preference.  Upon any voluntary or involuntary
              ----------------------                                    
     liquidation, dissolution or winding-up of the corporation, the holders of
     the Series D Preferred Stock will be entitled to receive out of the assets
     of the corporation available for distribution to stockholders, before any
     distribution of assets is made to the holders of shares of Common Stock, an
     amount in cash equal to $8.00 per share, plus an amount equal to all
     accumulated and unpaid dividends on such shares of Series D Preferred Stock
     to and including the date of such liquidation, dissolution or winding up.
     If, upon any voluntary or involuntary liquidation, dissolution or winding
     up of the corporation, the amounts payable with respect to the Series D
     Preferred Stock and any parity stock are not paid in full, the holders of
     the Series D Preferred Stock and such parity stock shall share ratably in
     any such distribution of assets of the corporation in proportion to the
     full respective preferential amounts (including accumulated and unpaid
     dividends) to which they are entitled.  After payment to the holders of the
     Series D Preferred Stock (including accumulated and unpaid dividends)
     provided for in this Section 6, the holders of Series D Preferred Stock
     shall be entitled to no further participation in any distribution of assets
     of the corporation.

          7.  Conversion Rights.  Holders of the Series D Preferred Stock shall
              -----------------                                                
     have no rights to convert the Series D Preferred Stock into any other class
     of capital stock of the corporation.

                                       13

 
          8. Cancellation of Redeemed Shares.  All shares of Series D Preferred
             -------------------------------                                   
     Stock redeemed pursuant to Section 4 shall be cancelled and shall not be
     issuable by the corporation, and the Articles of Incorporation shall be
     appropriately amended, if required, to effect the corresponding reduction
     in the corporation's authorized capital.

          9.  No Other Rights.  The shares of Series D Preferred Stock shall not
              ---------------                                                   
     have any preferences, voting powers or relative, participating or other
     special rights except as set forth above and in the Articles of

                               PUT/CALL AGREEMENT
                               ------------------

     THIS PUT/CALL AGREEMENT, dated _________ is among Eli Lilly and Company, an
Indiana corporation ("Lilly"), Integrated Medical Systems, Inc., a Colorado
corporation ("IMS"), and the person or entity or persons or entities whose name
or names appears on the signature page hereto as Holder (each, a "Holder").


                             PRELIMINARY STATEMENT
                             ---------------------

     Holder is the owner of shares of Common Stock or Series B Preferred Stock
of IMS, or is the owner of rights to acquire such shares pursuant to options or
warrants, as specified on the signature page hereof.

     Pursuant to an Agreement and Plan of Merger, dated as of August 2, 1995
(the "Merger Agreement"), following approval by the IMS shareholders, a
subsidiary of Lilly has been, or will be, merged into IMS (the "Merger"), and
upon the Merger the outstanding shares of Common Stock and certain outstanding
shares of Series B Preferred Stock have been, or will be, converted into cash or
shares of Series D Preferred Stock, par value $0.01 per share, of IMS (the "New
Preferred Stock").  In addition, rights to acquire Common Stock following the
Merger pursuant to options or warrants, or upon the conversion of Series B
Preferred Stock, have or will become rights to acquire New Preferred Stock.

     Holder may elect to receive shares of New Preferred Stock in the Merger
(the "Merger Shares") and/or to acquire additional shares of New Preferred Stock
following the Merger pursuant to the exercise of options or warrants or the
conversion of Series B Preferred Stock (the "Additional Shares").

     Holder and Lilly desire to grant each other certain rights regarding the
possible future purchase of such number of the Merger Shares and Additional
Shares as are specified on the signature page hereof (such Merger Shares and
Additional Shares so subject to the rights provided herein being herein called
the "Subject Shares").

     In order to facilitate the possible future purchase of the Subject Shares,
the parties will execute an Escrow Agreement (the "Escrow Agreement") with
___________

 
an agent named therein (the "Agent") substantially in the form of Exhibit A
hereto.


                                   AGREEMENT
                                   ---------

     The parties agree as follows:

     1.  PUT RIGHT.  (a)  Grant.  Lilly hereby grants to Holder, subject to the
         ---------        -----                                                
terms and conditions of this Agreement, the right to require Lilly (or Lilly's
designee(s)) to purchase any or all of the Subject Shares at the Purchase Price
(as defined below) during the Put Periods specified below.

     (b) Put Periods.  The initial Put Period shall be a period of at least 10
         -----------                                                          
business days beginning on the first anniversary of the Merger; the second Put
Period shall be a period of at least 10 business days beginning on ___________,
1998 [date to be about 30 months after Merger].  The Put Period shall be
specified in the applicable Put Notification (as defined below) and shall be
subject to extension, suspension or deferral as provided in Section 1(c) below.
During each Put Period, Holder may exercise the Put Right in whole or in part by
delivering to Lilly a Put Exercise Notice that specifies the number of Subject
Shares to be sold to Lilly during that Put Period.  A Put Exercise Notice shall
be revocable until such time as Lilly shall have delivered a Put Purchase
Certificate and thereafter shall not be revocable unless the Subject Shares
specified in such Put Exercise Notice are not purchased by Lilly within 45 days
after Lilly's receipt of the Put Exercise Notice, in which event the Put
Exercise Notice may be revoked by delivering written notice of revocation to
Lilly.

     (c) Extensions; Suspensions; Deferrals.  Lilly may elect, in its
         ----------------------------------                          
discretion, to extend any Put Period beyond the period specified in the Put
Notification.  In addition, Lilly shall have the right to defer commencement of
a Put Period, or to suspend a Put Period that has commenced, or to defer the
making of purchases pursuant to the Put Right, in order to permit compliance
with all applicable laws; provided, however, that Lilly will use its
                          --------  -------                         
commercially reasonable efforts to cause such compliance so as to avoid or
minimize any such deferral or suspension, except that if commencement or
continuation of a Put Period, or the making of purchases pursuant to the Put
Right, would require the disclosure to Holder of information about IMS or Lilly
that, in Lilly's reasonable judgment, it is not then in the best interests of
IMS or Lilly to disclose, Lilly may, in its discretion, defer the commencement
of, or may suspend, the Put Period or defer such purchases, for up to 90 days.
Lilly shall give prompt written notice of any such

                                       2

 
extension, suspension or deferral by sending an amended Put Notification to
Holder.  Any such extension, suspension or deferral shall not prevent Holder
from revoking Holder's Put Exercise Notice, as provided in Section 1(b) above.

     (d) Put Notification.  At least 10 and not more than 30 days prior to the
         ----------------                                                     
beginning of a Put Period, Lilly shall send a notice (the "Put Notification") to
Holder, together with a form of Put Exercise Notice to be used by Holder in
exercising the Put.  The Put Notification shall inform Holder of (i) the rights
of Holder to require Lilly to purchase the Subject Shares, (ii) the date of the
commencement and termination of the Put Period (subject to possible extension,
suspension or deferral pursuant to Section 1(c) above), (iii) the Purchase
Price, (iv) instructions as to how to exercise the Put and (v) the address to
which payment for the Purchase Price will be mailed unless Lilly receives notice
from Holder at least three business days prior to the purchase date that payment
should be mailed to another address, or should be sent, at Holder's expense, to
a specified address via a reputable overnight courier delivery service or
another delivery method reasonably acceptable to Lilly, or should be held by the
Agent for delivery at its office to Holder or Holder's authorized
representative.

     (e) Purchase and Payment.  At any time following receipt of a proper Put
         --------------------                                                
Exercise Notice, but not later than the third business day following the end of
a Put Period (as modified pursuant to Section 1(c) above), Lilly shall purchase
the Subject Shares covered by such Put Exercise Notice by delivering to the
Agent a Put Purchase Certificate executed on behalf of Lilly by an officer or
other authorized signatory that shall state:

          (1)  Lilly has received a Put Exercise Notice executed by Holder in
     compliance with this Agreement;

          (2)  Such Put Exercise Notice has not been revoked;

          (3)  The number of Subject Shares being sold pursuant to such Put
     Exercise Notice;

          (4)  The aggregate Purchase Price of such Subject Shares (net of any
     applicable taxes to be withheld pursuant to Section 3 below); and

          (5)  The name of Holder and the address to which payment for the
     aggregate Purchase Price should be mailed (or otherwise delivered in
     accordance with Holder's instructions as specified in the Put Exercise
     Notice);

                                       3

 
and shall deposit with the Agent funds sufficient to pay the aggregate
Purchase Price for such Subject Shares, and shall instruct the Agent to release
the certificates and related stock powers for such Subject Shares to Lilly and
as promptly as practicable to pay the aggregate Purchase Price to Holder.

          (f) Partial Exercise.  If the number of Subject Shares being sold by a
              ----------------                                                  
Holder pursuant to a Put Exercise Notice is less than the number of shares
represented by the relevant stock certificate held in escrow under the Escrow
Agreement, Lilly and IMS will cause a new certificate for the remaining shares
to be issued in the name of such Holder and deposited in such escrow.  Holder
will, if so requested by Lilly, execute and deliver to Lilly prior to the
purchase date under the Put Exercise Notice an undated stock power endorsed in
blank relating to such remaining shares, and Lilly will deposit such stock power
into the escrow.

          2.   CALL RIGHT.  (a)  Grant.  Holder hereby grants to Lilly, subject
               ----------        -----                                         
to the terms and conditions of this Agreement, the right to require Holder to
sell any or all of the Subject Shares to Lilly (or its designee(s)) at the
Purchase Price (the "Call Right").

          (b) Call.  Lilly may exercise the Call Right in whole at any time or
              ----                                                            
in part from time to time after the third anniversary of the Merger by giving
notice to Holder specifying the number of Subject Shares to be purchased and the
scheduled date of purchase, which date shall be at least 10 days after the date
such notice is given.  Lilly may revoke such notice, or may defer the scheduled
date of purchase, by giving notice to Holder at any time prior to Lilly's
purchase of Subject Shares pursuant to the Call notice.  On the purchase date,
Lilly shall deliver to the Agent a Call Purchase Certificate executed on behalf
of Lilly by an officer or other authorized signatory that shall state:

          (1)  Lilly has exercised its Call Right in compliance with this
     Agreement;

          (2)  Such exercise has not been revoked;

          (3)  The number of Subject Shares being purchased pursuant to such
     exercise;

          (4)  The aggregate Purchase Price of such Subject Shares (net of any
     applicable taxes to be withheld pursuant to Section 3 below); and

                                       4

 
          (5)  The name of Holder and the address to which payment for the
     aggregate Purchase Price should be mailed (or otherwise delivered in
     accordance with Holder's instructions received by Lilly at least three
     business days prior to the scheduled date of purchase);

and shall deposit with the Agent funds sufficient to pay the aggregate Purchase
Price for such Subject Shares, and shall instruct the Agent to release the
certificates and related stock powers for such Subject Shares to Lilly and as
promptly as practicable to pay the aggregate Purchase Price to Holder.

          3.   PURCHASE PRICE.  The Purchase Price shall be $8.00 per Subject
               --------------                                                
Share, plus any unpaid dividends accrued to the date on which Lilly deposits
funds with the Agent sufficient to pay the Purchase Price, but less any delivery
expenses to be charged to Holder in accordance with Section 1(d)(v) above.  If
the IMS Preferred Stock shall be split or combined, the Purchase Price shall be
appropriately adjusted.  The Purchase Price shall be paid by issuance of the
Agent's check, payable to Holder's order in New York Clearing House (next day)
funds.  Lilly shall be entitled to deduct and withhold from the Purchase Price
such amounts as Lilly is required to deduct and withhold with respect to the
making of such payment under the Internal Revenue Code, or any provision of
state, local or foreign tax law.  To the extent that amounts are so withheld by
Lilly, such withheld amounts shall be treated for all purposes of this Agreement
as having been paid to Holder.

          4.   ESCROW.  (a)  The parties hereto agree that the Agent will be a
               ------                                                         
bank or trust company with capital surplus and undivided profits of at least
$100 million and with offices located in New York City, Chicago or Denver (which
bank or trust company also may be the transfer agent and/or paying agent for the
New Preferred Stock), such Agent to be selected by Lilly and be reasonably
acceptable to IMS.

          (b)  Escrow of Merger Shares.  Holder is executing and delivering to
               -----------------------                                        
IMS an undated stock power endorsed in blank relating to the portion of the
Merger Shares subject to the rights herein provided.  Holder hereby authorizes
IMS to, and IMS will promptly following the Merger, insert into the stock power
the certificate numbers of the stock certificates representing such Merger
Shares and deliver to the Agent the certificates for such Merger Shares,
together with the stock power, to be held, and be subject to release, in
accordance with the Escrow Agreement.

          (c)  Escrow of Additional Shares.  If Holder acquires any Additional
               ---------------------------                                    
Shares subject to the rights herein provided, Holder agrees that Holder will
cause the

                                       5

 
certificates for such Additional Shares and, if there are not already on deposit
in the escrow sufficient appropriate stock powers, an undated stock power
endorsed in blank relating to such Additional Shares to be delivered to the
Agent to be held, and be subject to release, in accordance with the Escrow
Agreement.  Holder hereby authorizes IMS to cause any certificates for such
Additional Shares to be delivered directly to the Agent.

          5.   TRANSFERS OF SUBJECT SHARES.  Holder shall have the right to
               ---------------------------                                 
sell, assign, donate, pledge or otherwise transfer or encumber any or all of the
Subject Shares and any related rights and obligations under this Agreement only
with Lilly's prior written consent (any transfer or encumbrance being herein
called a "transfer").  Lilly will grant such consent provided that:

          (a)  the transferee shall have executed and delivered an agreement
reasonably satisfactory to Lilly confirming that the Subject Shares being
transferred will remain subject to this Agreement, including, without
limitation, the Call Right;

          (b) the certificates for the Subject Shares being transferred are or
remain deposited in the escrow with the Agent and the transferee shall have
executed and delivered to the Agent an undated stock power endorsed in blank
regarding those Subject Shares; provided, however, that if Holder wishes to make
a bona fide pledge to a bank, financial institution or brokerage firm, Lilly
will consent to the pledge and to the release from escrow and delivery to the
pledgee of the related stock certificates and stock powers provided the pledgee
shall have executed and delivered an agreement (which shall satisfy clause (a)
above) reasonably satisfactory to Lilly confirming that the pledged shares will
remain subject to this Agreement and that upon release of the pledge the pledged
shares will be returned to the Agent for deposit in the escrow and that upon any
exercise of the Call Right the certificates and stock powers for the pledged
shares will be delivered to Lilly, free and clear of the pledge or any claim or
encumbrance created thereby; and

          (c) Lilly is reasonably satisfied that the transfer (i) will comply
with all applicable Federal and state securities laws and other applicable legal
requirements and (ii) will not result in the outstanding New Preferred Stock
being held of record by 500 or more persons within the meaning of Section 12(g)
of the Securities Exchange Act of 1934, as amended, and the rules and
regulations thereunder.

                                       6

 
          6.  LEGENDS.  Each certificate representing the Subject Shares shall
              -------                                                         
bear the following legend:

          "The shares represented hereby are subject to (i) redemption by the
          Corporation during the periods, at the prices and on the terms and
          conditions specified in the Articles of Incorporation, (ii) an option
          on the part of the holder to require Eli Lilly and Company to
          purchase, and an option on the part of Eli Lilly and Company to
          require the holder to sell, such shares, at the times and at the
          prices and on the terms and conditions specified in a Put/Call
          Agreement and a related Escrow Agreement, both dated as of ________,
          1995, copies of which are available for inspection at the
          Corporation's executive offices.  These shares are not transferrable
          except as provided in the Put/Call Agreement."

          7.   NO RESTRICTIONS ON LILLY.  (a)  Holder hereby acknowledges that
               ------------------------                                       
the existence of the Put Right and the Call Right will not impair or restrict in
any way Lilly's right, following the Merger, to transfer all or any of its
interest in IMS or to cause IMS to merge, sell its assets or engage in other
extraordinary transactions, including, without limitation, transactions that
would result in the cashing out of the New Preferred Stock or the exchange of
the New Preferred Stock for other securities, except that prior to the third
anniversary of the Merger Lilly will not cause IMS to engage in a merger or
other extraordinary transaction that would result in Holder's being deemed for
Federal income tax purposes to have sold Subject Shares in such merger or other
extraordinary transaction.  Lilly represents that, as of this Agreement, it has
no present intention to cause IMS to engage in such a merger or other
extraordinary transaction prior to the fifth anniversary of the Merger.

          (b) If pursuant to a merger, consolidation, recapitalization,
reorganization, sale of substantially all of the assets or other such
transaction involving IMS, the outstanding shares of New Preferred Stock are
converted into or exchanged for cash, property or securities of IMS or any other
issuer, then the Put Right and the Call Right shall apply to such cash, property
or securities and the Purchase Price and other terms hereof shall be subject to
appropriate adjustment, so as to preserve unchanged to the fullest extent
possible the rights and obligations of the parties to this Agreement.

                                ESCROW AGREEMENT


     This Escrow Agreement, dated as of ______________, 1995, by and among Eli
Lilly and Company, an Indiana corporation ("Lilly"), Integrated Medical Systems,
Inc., a Colorado corporation ("IMS"), one or more shareholders of IMS identified
on the signature pages hereof ("Holders") and _________________, a

                             PRELIMINARY STATEMENT
                             ---------------------

     Each Holder is the owner of shares of Common Stock or Series B Preferred
Stock of IMS, or is the owner of rights to acquire such shares pursuant to
options or warrants or the conversion of convertible securities.

     Pursuant to an Agreement and Plan of Merger, dated as of August 2, 1995
(the "Merger Agreement"), following approval by the IMS shareholders, a
subsidiary of Lilly has been or will be merged into IMS (the "Merger"), and upon
the Merger the outstanding shares of Common Stock and certain outstanding shares
of Series B Preferred Stock of IMS have been or will be converted into cash or
shares of Series D Preferred Stock of IMS (the "New Preferred Stock").  In
addition, rights to acquire Common Stock of IMS pursuant to

 
options or warrants or the conversion of Series B Preferred Stock have or will
become rights to acquire New
Preferred Stock.

     Lilly, IMS and Holders have entered into Put/Call Agreements pursuant to
which Holders and Lilly have granted each other certain rights regarding the
possible future purchase of some or all of the New Preferred Stock that such
Holders may acquire (the "Subject Shares").

     Lilly, IMS and Holders desire that the stock certificates and related stock
powers for the Subject Shares be held in escrow pending the possible purchase
thereof pursuant to the Put/Call Agreements.

                                   AGREEMENT
                                   ---------

     Section 1.   Establishment of Escrow.
                  ----------------------- 

     Lilly, IMS or any Holder may from time to time deliver to the Escrow
Agent certificates representing Subject Shares registered in the name of Holder
and undated stock powers endorsed in blank by such Holder relating to those
Subject Shares (such certificates and stock powers are herein called "Escrowed
Shares").  Escrowed Shares shall be held, administered and disposed of by the
Escrow Agent in accordance with the terms and conditions of this Escrow

                                       2

 
Agreement.  The Escrow Agent shall deliver promptly to Lilly and IMS written
notice of the receipt by the Escrow Agent of any Escrowed Shares that are
delivered by a Holder rather than by Lilly or IMS.

          Section 2.   Custody and Release.
                       ------------------- 

          (a) The Escrow Agent shall act as custodian of the Escrowed Shares.

          (b) Upon delivery by Lilly to the Escrow Agent of one or more Put
Purchase Certificates or Call Purchase Certificates, together with funds
sufficient to pay the aggregate Purchase Price for the Escrowed Shares specified
in such Certificates, the Escrow Agent shall immediately release such Escrowed
Shares to Lilly.  In addition, the Escrow Agent shall as promptly as
practicable, and in any event not later than five business days after Lilly
delivery of such Certificates, issue its checks payable to the order of the
Holders specified in the Put Purchase Certificates or Call Purchase
Certificates.  Such checks shall be in New York Clearing House funds and shall
be sent to the addresses and in the manner specified in the applicable Put
Purchase Certificates or Call Purchase Certificates.  As used in this Escrow
Agreement, a Put Purchase Certificate shall mean a properly executed Certificate
substantially in the form of Exhibit 1 attached hereto, and a Call Purchase
Certificate

                                       3

 
shall mean a properly executed Certificate substantially in the form of Exhibit
2 attached hereto.

          (c) Upon delivery to the Escrow Agent of instructions signed by Lilly
and any Holder to release any Escrowed Shares held of record by such Holder, the
Escrow Agent shall immediately release such Escrowed Shares to such Holder in
accordance with such instructions.

          (d) If for any reason the Escrow Agreement has not been terminated by
December 31, 2001, the Escrow Agent shall release promptly all Escrowed Shares
to the respective Holders who are the record owners thereof.

Agent and reasonably satisfactory to Lilly and IMS]

Suite 400
Golden, Colorado 80401


Members of the Board:

        You have requested our opinion as to the fairness, from a financial
point of view, of the consideration to be offered to the holders of the common
stock of Integrated Medical Systems, Inc. (the "Company"), other than Eli Lilly
and Company and its subsidiaries (collectively, "Lilly"), and the holders of the
Series B Preferred Stock of the Company (the holders of common stock and Series
B Preferred Stock of the Company, other than Lilly, are hereinafter collectively
referred to as the "Majority Shareholders"), pursuant to the Agreement and Plan
of Merger, dated as of July 31, 1995, by and among Eli Lilly and Company, Trans-
IMS Corporation (the "Subsidiary") and the Company (together with the exhibits
thereto, the "Merger Agreement"), As more fully described in the Merger
Agreement, and subject to the terms and conditions specified therein, the
Subsidiary shall be merged with and into the Company (the "Merger") and (a) each
holder of common stock of the Company (other than Lilly) will have the
opportunity to elect to receive, for each share held, either $8.00 in cash or
one share of newly issued Series D Preferred Stock ("Series D Preferred Stock")
of the Company and (b) each holder of Series B Preferred Stock of the Company
will have the opportunity to elect to receive, for each share held, either $5.33
in cash or 2/3 of a share of Series D Preferred Stock, in each case subject to
dissenters' appraisal rights (such cash elections and stock elections to be
offered to such shareholders pursuant to the Merger Agreement are hereinafter
collectively referred to as the "Merger Consideration").


The Board of Directors
Integrated Medical Systems, Inc.

        In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers, directors and other representatives
and advisors of the Company concerning the business, operations and prospects of
the Company. We participated in discussions and negotiations among
representatives of the Company and Lilly and their financial and legal advisors.
We examined certain business and financial information relating to the Company
as well as certain financial forecasts and other data which were provided to us
by the management of the Company. We reviewed the financial terms of the Merger 
Consideration in relation to, among other things, the Company's historical and
projected earnings and the capitalization and financial condition of the
Company. We also considered, to the extent publicly available, the financial
terms of certain other transactions which we deemed comparable to the Merger and
analyzed certain financial and other publicly available information relating to
the businesses of other companies whose operations we considered comparable to
the Company. In addition, we conducted such other analyses and examinations and
considered such other financial, economic and market criteria as we deemed
necessary to arrive at our opinion.

        In rendering our opinion, we have assumed and relied upon, without
independent verification, the accuracy and completeness of all financial and
other information publicly available or furnished to or otherwise reviewed by or
discussed with us. Except as described above, we have not conducted any review
or investigation of the Company or Lilly. With respect to financial forecasts
and other information provided to or otherwise reviewed by or discussed with us,
we assumed that such forecasts and other information were reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
management of the Company as to the expected future financial performance of the
Company. We have not made or been provided with an independent valuation or
appraisal of the assets, liabilities (contingent or otherwise) or reserves of
the Company nor have we made any physical inspection of the properties or assets
of the Company. We have assumed the correctness of and relied upon the
representations and warranties of the Company, the Subsidiary and Eli Lilly and
Company in the Merger Agreement and have not attempted to independently verify
the same. We were not asked to, and did not, solicit acquisition proposals from
any third parties. Our opinion is necessarily based upon information available
to us, and financial, stock market and other conditions and circumstances
existing and disclosed to us, as of the date hereof.

        Our opinion does not address the relative merits of the Merger as 
compared to any alternative business strategies that might exist for the Company
or the effect of any other transaction in which the Company may engage.

        We were not asked to, and do not, express any opinion as to the relative
merits of receiving the cash consideration or the stock consideration in the 
Merger and accordingly, this opinion is not intended to be and shall not be 
deemed to be a recommendation to any shareholder as to whether or not to make a 
cash election.  In addition, we were not asked to, and do not, express any 
opinion as to (a) what the value of the Series D Preferred Stock actually will 
be when issued to shareholders of the Company pursuant to the Merger - or the 
price at which the Series D Preferred Stock will trade, if at all, subsequent to
the Merger, (b) any election by any shareholder of the Company to retain 
shares of Series B Preferred Stock of the Company or (c) the relative fairness 
of the Merger to the holders of the common stock of the Company and the holders 
of the Series B Preferred Stock of the Company.

        Smith Barney has been engaged to render financial advisory services 
to the Company in connection with the Merger and will receive a fee for our 
services, a significant portion of which is contingent upon completion of the 
Merger. We will also receive a fee upon delivery of this opinion. In the 
regular course of our business, we and our affiliates may actively trade the 
equity and debt securities of Lilly for our own account or for the account of 
our  customers and, accordingly, may at any time hold a long or short 
position in such securities. In addition, we and our affiliates (including The 
Travelers Inc. and its affiliates) may maintain business relationships with the 
Company, Lilly and their affiliates.

        Our advisory services, and the opinion expressed herein, are provided 
solely for the use of the Company (including its Board of Directors) in its 
evaluation of the proposed Merger and are not on behalf of, and are not intended
to confer rights or remedies upon, Lilly, any stockholder of the Company or 
Lilly, or any person other than the Board of Directors or the Company. Our 
opinion may not be published or otherwise used or referred to, nor shall any 
public reference to Smith Barney be made, without our prior written consent, 
except that we consent to disclosure of this opinion in the proxy statement 
relating to the Merger so long as such disclosure is provided to us and our 
counsel for review and comment prior to its publication. This opinion is not 
intended to be and shall not be deemed to be a recommendation to any stockholder
of the Company to vote in favor of the Merger.

        Based upon and subject to the foregoing, our experience as investment 
bankers, our work as described above and other factors we deemed relevant, we

offered to the Majority Shareholders pursuant to the Merger Agreement is fair, 
from a financial point of view, to the Majority Shareholders.

vote is required under section 7-112-102(1); and

     (d) Consummation of a sale, lease, exchange, or other disposition of all,

     (2) A shareholder, whether or not entitled to vote, is entitled to dissent
and obtain payment of the fair value of the shareholder's shares in the event

     (II) Creates, alters, or abolishes a right in respect of redemption of the
shares, including a provision respecting a sinking fund for their redemption or
repurchase; or

respect of the shares because it:

     (I) Excludes or limits the right of the shares to vote on any matter, or to
cumulate votes, other than a limitation by dilution through issuance of shares
or other securities with similar voting rights; or

     (II) Reduces the number of shares owned by the shareholder to a fraction of

value of the shareholder's shares in the event of any corporate action to the
extent provided by the bylaws or a resolution of the board of directors.

shareholder's shares under this article may not challenge the corporate action
creating such entitlement unless the action is unlawful or fraudulent with
respect to the shareholder or the corporation.

     7-113-103  DISSENT BY NOMINEES AND BENEFICIAL OWNERS.--(1)  A record
shareholder may assert dissenters' rights as to fewer than all the shares
registered in the record shareholder's name only if the record shareholder
dissents with respect to all shares beneficially owned by any one person and
causes the corporation to receive written notice which states such dissent and
the name, address, and federal taxpayer identification number, if any, of each
person on whose behalf the record shareholder asserts dissenters' rights.  The
rights of a record shareholder under this subsection (1) are determined as if
the shares as to which the record shareholder dissents and the other shares of
the record shareholder were registered in the names of different shareholders.

     (2) A beneficial shareholder may assert dissenters' rights as to the shares
held on the beneficial shareholder's behalf only if:

     (a) The beneficial shareholder causes the corporation to receive the record
shareholder's written consent to the dissent not later than the time the
beneficial shareholder asserts dissenters' rights; and

     (b) The beneficial shareholder dissents with respect to all shares
beneficially owned by the beneficial shareholder.

     (3) The corporation may require that, when a record shareholder dissents
with respect to the shares held by any one or more beneficial shareholders, each
such beneficial shareholder must certify to the corporation that the beneficial
shareholder and the record shareholder or record shareholders of all shares
owned beneficially by the beneficial shareholder have asserted, or will timely
assert, dissenters' rights as to all such shares as to which there is no
limitation on the ability to exercise dissenters' rights.  Any such requirement
shall be stated in the dissenters' notice given pursuant to section 7-113-203.

corporation's principal office is located or, if it has no principal office in
this state, in the district court of the county in which its registered office
is located.  If the corporation is a foreign corporation without a registered
office in this state, it shall commence the proceeding in the county in this

                       COLORADO BUSINESS CORPORATION ACT

     (3) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unresolved parties to the proceeding commenced
under subsection (2) of this section as in an action against their shares, and
all parties shall be served with a copy of the petition.  Service on each
dissenter shall be by registered or certified mall, to the address stated in
such dissenter's payment demand, or if no such address is stated in the payment
demand, at the address shown on the corporation s current record of shareholders
for the record shareholder holding the dissenter's shares, or as provided by
law.

     (4) The jurisdiction of the court in which the proceeding is commenced
under subsection (2) of this section is plenary and exclusive.  The court may
appoint one or more persons as appraisers to receive evidence and recommend a
decision on the question of fair value.  The appraisers have the powers
described in the order appointing them, or in any amendment to such order.  The
parties to the proceeding are entitled to the same discovery rights as parties
in other civil proceedings.

     (5) Each dissenter made a party to the proceeding commenced under
subsection (2) of this section is entitled to judgment for the amount, if any,
by which the court finds the fair value of the dissenter's shares, plus
interest, exceeds the amount paid by the corporation, or for the fair value,
plus interest, of the dissenter's shares for which the corporation elected to
withhold payment under section 7-113-208.

     7-113-302  COURT COSTS AND COUNSEL FEES.--(1)  The court in an appraisal
proceeding commenced under section 7-113-301 shall determine all costs of the
proceeding, including the reasonable compensation and expenses of appraisers
appointed by the court.  The court shall assess the costs against the
corporation; except that the court may assess costs against all or some of the
dissenters, in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under section 7-113-209.

     (2) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:

     (a) Against the corporation and in favor of any dissenters if the court
finds the corporation did not substantially comply with the requirements of part
2 of this article; or

     (b) Against either the corporation or one or more dissenters, in favor of
any other party, if the court finds that the party against whom the fees and
expenses are assessed acted arbitrarily, vexatiously, or not in good faith with
respect to the rights provided by this article.

     (3) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to said counsel reasonable fees to be paid out of the amounts awarded to
the dissenters who were benefitted.

         ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

              Eli Lilly and Company

              Sections 23-1-37-1 to 23-1-37-15 of the Indiana Business
         Corporation Law give Indiana corporations broad powers to indemnify
         their directors and officers and those of affiliated corporations
         against liability incurred in any proceeding to which they are made
         parties by reason of being or having been such directors or officers,
         subject to specified conditions and exclusions; authorizes the payment
         for or reimbursement of reasonable expenses incurred by such persons in
         such proceedings; gives a director or officer who successfully defends
         a proceeding the right to be so indemnified; and authorizes Indiana
         corporations to buy directors' and officers' liability insurance.  Such
         indemnification is not exclusive of any other rights to which those
         indemnified may be entitled under the corporation's articles of
         incorporation or by-laws, resolution of the board of directors or
         stockholders or otherwise.


           Article 12(g) of the Amended Articles of Incorporation
           of Lilly provides as follows:

              "The Corporation shall indemnify each person who is or was a
         director, officer or employee of the Corporation, or of any other
         corporation which he is serving or served in any capacity at the
         request of the Corporation, against any and all liability and
         reasonable expense that may be incurred by him in connection with or
         resulting from any claim, action, suit, or proceeding (whether actual
         or threatened, brought by or in the right of the Corporation or such
         other corporation or otherwise, civil, criminal, administrative,
         investigative, or in connection with an appeal relating thereto), in
         which he may become involved, as a party or otherwise, by reason of his
         being or having been a director, officer, or employee of the
         Corporation or of such other corporation, or by reason of any past or
         future action taken or not taken in his capacity as such director,
         officer, or employee, whether or not he continues to be such at the
         time such liability or expense is incurred, provided such person acted
                                                     --------                  
         in good faith, in what he reasonably believed to be the best interests
         of the Corporation or such other corporation, as the case may be, and,
         in addition, in any criminal action or proceeding, had no reasonable
         cause to believe that his conduct was unlawful.  As used in this
         Article 12(g), the terms "liability" and "expense" shall include, but
         shall not be limited to, attorneys' fees and disbursements and amounts
         of judgments, fines, or penalties against, and amounts paid in
         settlement by, a director, officer, or employee.  The termination of
         any claim, action, suit, or proceeding, civil or criminal, by judgment,
         settlement (whether with or without court approval) or conviction or
         upon a plea of guilty or of nolo contendere, or its equivalent, shall
         not create a presumption that a director, officer, or employee did not
         meet the standards of conduct set forth in the first sentence of this
         Article 12(g).

              "Any such director, officer, or employee who has been wholly
         successful, on the merits or otherwise, with respect to any claim,
         action, suit, or proceeding of the character described herein shall be
         entitled to indemnification as of right.  Except as provided in the
         preceding sentence, any indemnification hereunder shall be made at the
         discretion of the Corporation, but only if (1) the Board of Directors,
         acting by a quorum consisting of directors who are not parties to or
         who have been wholly successful with respect to such claim, action,
         suit or proceeding, shall find that the director, officer, or employee
         has met the standards of conduct set forth in the first sentence of
         this Article 12(g), or (2) independent legal counsel (who may be
         regular counsel of the Corporation) shall deliver to it their written
         opinion that such director, officer, or employee has met such
         standards.

                                      II-1

 
              "If several claims, issues, or matters of action are involved, any
         such person may be entitled to indemnification as to some matters even
         though he is not so entitled as to others.

              "The Corporation may advance expenses to, or where appropriate may
         at its expense undertake the defense of, any such director, officer or
         employee upon receipt of an undertaking by or on behalf of such person
         to repay such expenses if it should ultimately be determined that he is
         not entitled to indemnification under this Article 12(g).

              "The provisions of this Article 12(g) shall be applicable to
         claims, actions, suits or proceedings made or commenced after the
         adoption hereof, whether arising from acts or omissions to act
         occurring before or after the adoption hereof.

              "The rights of indemnification provided hereunder shall be in
         addition to any rights to which any person concerned may otherwise be
         entitled by contract or as matter of law, and shall inure to the
         benefits of the heirs, executors, and administrators of any such
         person."

              Lilly has insurance coverages indemnifying directors, officers and
         certain other employees for expenditures incurred by them in connection
         with certain acts in their capacities as such, and providing
         reimbursement to Lilly for expenditures in indemnifying directors,
         officers and other insured employees for such acts.  The maximum
         aggregate coverage for Lilly and insured individuals is currently
         $130,000,000 per policy year, with the policies subject to self-
         retention and deductible provisions.  Reference is made to the Cover
         Notes for Directors and Officers Liability including Company
         Reimbursement insurance coverage and Excess Directors and Officers
         Liability and Corporate Reimbursement coverage filed as Exhibit 6 to
         Lilly's Registration Statement No. 2-66741 and incorporated herein and
         made a part hereof.

              Lilly also has insurance coverage indemnifying directors,
         officers, and employees for expenditures incurred by them as a result
         of liabilities that may be imposed under the Employee Retirement Income
         Security Act of 1974 by reason of their acting as fiduciaries in
         relation to certain employee benefit plans of Lilly.  The maximum
         aggregate coverage under such insurance is currently $20,000,000 per
         policy year, with the policy subject to deductible provisions.

              (b)  Financial Statement Schedules

              (c)  Information Provided Pursuant to Item 4(b)

                   Fairness Opinion provided by Smith Barney Inc. is included as
         Appendix C to the Proxy Statement-Prospectus.

         ITEM 22.  UNDERTAKINGS.

              The undersigned registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act of 1933, each filing
         of the registrant's annual report pursuant to section 13(a) or section
         15(d) of the Securities Exchange Act of 1934 (and, where applicable,
         each filing of an employee benefit plan's annual report pursuant to
         section 15(d) of the Securities Exchange Act of 1934) that is
         incorporated by reference in the registration statement shall be deemed
         to be a new registration statement relating to the

                                      II-4

 
         securities offered therein, and the offering of such securities at that
         time shall be deemed to be the initial bona fide offering thereof.

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

              The undersigned registrant hereby undertakes as follows:  that
         prior to any public reoffering of the securities registered hereunder
         through use of a prospectus which is a part of this registration
         statement, by any person or party who is deemed to be an underwriter
         within the meaning of Rule 145(c), the issuer undertakes that such
         reoffering prospectus will contain the information called for by the
         applicable registration form with respect to reofferings by persons who
         may be deemed underwriters, in addition to the information called for
         by the other Items of the applicable form.

              The registrant undertakes that every prospectus (i) that is filed
         pursuant to the immediately preceding paragraph, or (ii) that purports
         to meet the requirements of section 10(a)(3) of the Act and is used in
         connection with an offering of securities subject to Rule 415, will be
         filed as a part of an amendment to the registration statement and will
         not be used until such amendment is effective, and that, for purposes
         of determining any liability under the Securities Act of 1933, each
         such post-effective amendment shall be deemed to be a new registration
         statement relating to the securities offered therein, and the offering
         of such securities at that time shall be deemed to be the initial bona
         fide offering thereof.

              The undersigned registrant hereby undertakes to respond to
         requests for information that is incorporated by reference into the
         prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within
         one business day of receipt of such request, and to send the
         incorporated documents by first class mail or other equally prompt
         means.  This includes information contained in documents filed
         subsequent to the effective date of the registration statement through
         the date of responding to the request.

              The undersigned registrant hereby undertakes to deliver or cause
         to be delivered with the prospectus, to each person to whom the
         prospectus is sent or given, the latest annual report to security
         holders that is incorporated by reference in the prospectus and
         furnished pursuant to and meeting the requirements of Rule 14a-3 or
         Rule 14c-3 under the Securities Exchange Act of 1934; and, where
         interim financial information required to be presented by Article 3 of
         Regulation S-X is not set forth in the prospectus, to deliver, or cause
         to be delivered to each person whom the prospectus is sent or given,
         the latest quarterly report that is specifically incorporated by
         reference in the prospectus to provide such interim financial
         information.

                   The undersigned registrant hereby undertakes to supply by
         means of post-effective amendment all information concerning a
         transaction, and the company being acquired involved therein, that was
         not the subject of and included in the registration statement when it
         became effective.
