      3.1 Grant of License.

            3.1.1 InterQual hereby grants to Licensee the nontransferable,
      nonexclusive right to use the Criteria for incorporation into the Maxsys
      solely for the purpose of sublicensing the Criteria to Sublicensees in the
      United States, Canada and the United Kingdom in the operation of their
      respective businesses (the "License").

            3.1.2 InterQual hereby grants to Licensee the non-exclusive right to
      use the Marks solely for the purpose of identifying InterQual as creator
      and owner of the Criteria in the Maxsys and in promotional, advertising
      and operational materials, except that any reference to the Criteria in
      such literature is subject to InterQual's review and written approval,
      which shall not be unreasonably withheld. The floppy disk mailers,
      screens, labels, packaging materials, and manuals contained within the
      Maxsys shall include "TM" after the appropriate Marks plus a footnote
      containing the language set forth below, reflecting InterQual's ownership
      interest in and to its copyrights and trademarks, which language may by
      revised from time to time by InterQual:

            This software contains criteria created and published by InterQual,
            Incorporated under its ISD-A(TM), IPM-A(TM) and SIM(TM) trademarks.
            InterQual is and will remain the sole owner of copyrights in such
            data and

                                       2
<PAGE>   4

            the good will symbolized by the respective system trademarks.

      Licensee shall submit to InterQual for approval prior to first public use,
      a sample of each program, manual, label, packaging material or other thing
      which bears the ISD-A, IPM-A or SIM trademark. Such approval shall be
      deemed given unless within ten (10) business days after the respective
      submission, InterQual notifies Licensee in writing of InterQual's
      objections to publication of same.

            3.1.3 InterQual shall have the right to publicize this Licensing
      Agreement with Licensee in any advertising or publicity releases, subject
      to the prior written approval of Licensee which shall not be unreasonably
      withheld and which approval shall be given in a timely manner.

      3.2 Grant of Right to Sublicense.

            3.2.1 InterQual hereby grants to Licensee the right to sublicense
      the Criteria in the hospital market to Sublicensees subject to the terms
      and conditions of this Agreement. All such sublicenses shall be subject to
      the written approval of InterQual and Licensee shall provide InterQual
      with a copy of each such sublicense prior to the execution of the
      sublicense agreement between Licensee and Sublicensee. Licensee agrees to
      provide, on an annual basis, written notification to InterQual of all of
      the names, addresses and principal representatives of the Sublicensees.

            3.2.2 All of the rights, obligations and conditions provided herein
      relative to the License shall apply to the Sublicensees, and Licensee
      shall cause its Sublicensees to comply with all of the terms and
      provisions of this Agreement.

            3.2.3 Licensee acknowledges that InterQual may have claims against a
      Sublicensee for its unauthorized use of the Criteria and the Marks prior
      to the execution of this Agreement, and Licensee, its employees, officers,
      agents shall not represent to any Sublicensee that the execution of a
      sublicense agreement between Licensee and Sublicensee in any way affects
      InterQual's claims against Sublicensee regarding Sublicensee's past use of
      the Criteria, or a derivative thereof, prior to the execution of this
      Agreement.

      3.3 Non-transferability of License. The License shall be nondivisible and
          Licensee shall not sublicense, except as provided in Section 3.2, or
          in any manner transfer or assign the rights granted herein without the
          prior written consent of InterQual. Subject to Section 3.2, InterQual
          shall have the absolute right to withhold its approval of any
          sublicense.

      3.4 Non-Exclusive License. The License granted herein shall be
          non-exclusive and InterQual shall have the right to license the
          Licensed Property to any other party for any other purpose.

      3.5 Updates and Modifications.

            3.5.1 InterQual shall provide Modifications developed by InterQual
      to the Criteria at no additional cost to Licensee, which Modifications
      shall be issued by InterQual, at its sole discretion, and according to a
      schedule determined by InterQual.

            3.5.2 Licensee shall incorporate the Modifications of InterQual or
      approved by InterQual into the Maxsys in the next annual release of the
      Maxsys ("Annual Release"). Licensee shall provide InterQual with six (6)
      months prior written notice of the submission date for the Modifications
      for inclusion in the Annual Release.

            3.5.3 Subject to this Section 3.5.3, Licensee and any Sublicensee
      shall have the right to create Modifications. Licensee shall only be able
      to Sublicense the Modifications in accordance with the terms of this
      Agreement. During the term of this Agreement, such modifications shall be
      used by Sublicensee for internal purposes only. Licensee or any
      Sublicensee desiring to create a Modification shall, by written notice to
      InterQual, request approval of such Modifications. InterQual shall use all
      reasonable efforts to review such Modifications and to communicate its
      approval or denial within thirty (30) days of the receipt of the request.
      If InterQual does not approve the Modification, the Licensee and any
      Sublicensee shall still be entitled to incorporate the Modification into
      the Maxsys as further described in paragraph 3.5.5 hereof, provided,
      however, that the Licensee and such Sublicensee shall thereafter
      acknowledge, in writing, and on the Maxsys that the version of the
      Criteria it uses contains user-initiated changes not specifically approved
      by InterQual. After the term of this Agreement, Licensee and Sublicensee
      shall not be entitled to use, sell or license the Modifications to others.
      The obligations set forth in this Section 3.5.3 shall survive the
      termination of this Agreement.

            3.5.4 If Licensee shall charge a fee to a Sublicensee for a software
      modification related to a Modification, InterQual may charge such
      Sublicensee, at its current fee schedules, for reviewing, approving or
      processing the Modification.

            3.5.5 Licensee shall provide the following features in each copy of
      a Maxsys:

                  (i) an automatic mark that identifies any non-InterQual
            approved Modification made by a Sublicensee to the Criteria
            indicating that such Modification is "User Specific"; and

                  (ii) an automatic notice on the title or acknowledgement
            screen of a Maxsys which is activated whenever any User Specific
            Modification has been implemented that indicates that the User
            Specific Changes are included in the Criteria.

                                       4

            3.5.6 Consulting and Training. In conjunction with the grant of the
      License, Licensee shall inform its Sublicensees of the incorporation of
      the Criteria into the Maxsys and of the availability of InterQual to
      provide training and consultation services with respect to the Criteria.
      InterQual shall, upon request of Licensee or Sublicensees, provide such
      training and consultation services at its then current fee schedules.
      Licensee shall not be entitled to any portion of the fees charged by
      InterQual.

4. Licensee's Obligations/Responsibilities. Licensee will, in connection with
the sublicensing of the Criteria, in addition to its other obligations herein,
assume responsibility for the following:

      4.1 Licensee shall provide, at its sole expense, to Sublicensee any
          technical support including initial and ongoing maintenance (including
          the inclusion of any Modifications) for the installation and
          maintenance of the Criteria during the term of this Agreement.
          Licensee shall provide the technical support in a professional and
          workman like manner.

      4.2 Licensee shall refer Sublicensee's inquiries regarding the content of
          the Criteria to InterQual following software installation.

      4.3 Licensee agrees to assume responsibility for its own expenses in a
          mandatory annual sales meeting with InterQual to review the
          relationship, assess sales and marketing strategies and identify new
          opportunities.

      4.4 Licensee shall keep complete, accurate and up-to-date books and
          records in accordance with generally accepted accounting principles
          and sound business practice covering all transactions relating to
          Sublicensees, and Licensee shall no less than on a quarterly basis
          provide to InterQual a written accounting of all executed and
          prospective sublicense agreements. Licensee shall pay to InterQual the
          license and marketing fees within thirty (30) days of the date it
          receives the license fee from Sublicensee. If license and marketing
          fees are not paid pursuant to the terms set forth in this paragraph
          4.4, InterQual may charge, in its sole discretion, Licensee interest
          at the rate of one (1%) percent per month, in addition to such other
          rights as it may have. Except as provided in paragraph 11.3.4,
          Licensee shall not be entitled to any refund of any license fee for
          Criteria purchased by Sublicensee should a Sublicensee terminate its
          agreement with Licensee for Software.

      4.5 InterQual and/or its authorized representatives shall upon reasonable
          notice have the right to inspect, audit, and/or copy such records in
          order to determine whether all provisions of the Agreement have been
          met. InterQual agrees that all information and records obtained in
          such audit shall not be disclosed to authorized persons unless
          required to do so by law

                                       5
<PAGE>   7
          or legal action. InterQual shall also have the right to audit as
          described in this paragraph 4.4 for two years following the
          termination date of this Agreement by lapse of time or otherwise.

      4.6 Licensee agrees to notify InterQual promptly, in writing, of the
          existence of any circumstances surrounding any unauthorized copying,
          reproduction, alteration, use or distribution of the Criteria by any
          entity.

      4.7 Upon the execution of this Agreement, Licensee shall furnish
          InterQual, without charge, with one (1) copy of the Maxsys, manuals
          and documentation related thereto, and with all updates, enhancements
          and improvements. InterQual shall use the Maxsys solely for inspection
          and verification of the use of the Licensed Property, except to the
          extent it obtains Licensee's express written approval to use the
          Maxsys for demonstration purposes to existing and prospective clients
          of InterQual. To the extent it is not feasible for Licensee to provide
          InterQual with a copy of the Maxsys for inspection and verification
          purposes (i.e. due to technical reasons including hardware
          requirements and operating system requirements), Licensee may provide
          InterQual with modem access to the Maxsys, during regular business
          hours without charge for inspection and verification.

5. InterQual's Obligations/Responsibilities. InterQual will, in connection with
the sublicensing of the Criteria, in addition to its other obligations herein,
assume responsibility for the following:

      5.1 Upon execution of this Agreement, provide Licensee with one (1) copy
          of each of the following:

            5.1.2 One complete set of the most current version of the Criteria
                  in hard copy;

            5.1.3 One copy of the diskette loaded with the data files containing
                  the Criteria.

      5.2 InterQual shall provide up to a maximum of eight (8) hours per year of
          telephone support to Licensee for assistance in the integration of the
          Criteria into the Software. Additional consulting support, both by
          telephone and on-site is available to Licensee following the initial
          eight (8) hours at InterQual's current fee schedule for its technical
          support staff.

      5.3 InterQual agrees to assume responsibility for its own expenses in
          attending the mandatory annual sales meeting with Licensee.

6. License Fee. As consideration for the right to sublicense the Licensed
Property,

                                       6
<PAGE>   8
Licensee shall pay to InterQual a license fee as set forth in Exhibit 6.

7. Marketing Fees. Licensee agrees to pay InterQual a ten percent (10%)
marketing fee for prospective clients who are not currently "active" clients of
Licensee ("active" meaning clients who have previously been in direct contact
with the sales force of Licensee regarding Maxsys) and who have become
interested in Maxsys because of InterQual's direct involvement and InterQual
notifies Licensee in writing of the circumstances, and without further
participation of InterQual the contact results in the execution of a license
agreement with or without the inclusion of the Criteria between the prospective
client and Licensee. To the extent the license agreement includes the Criteria,
Licensee would pay InterQual the ten percent (10%) marketing fee in addition to
that provided in Exhibit 6.

            8.1.1 Licensee acknowledges and its Sublicensees shall acknowledge

      to the Licensed Property or affect the validity of the Licensed Property
      or depreciate the value of the Licensed Property or its established
      prestige and goodwill. Licensee acknowledges and its Sublicensees shall
      acknowledge that use of the Licensed Property shall not create in favor of
      Licensee or its Sublicensees any right, title or interest in or to the
      Licensed Property and all uses of the Licensed Property by Licensee and
      its Sublicensees shall inure to the benefit of InterQual. Licensee and
      Sublicensee shall assign to InterQual as such things are created, all of

              8.2.2 In connection with the use of the Maxsys, InterQual shall
      not in any manner represent that it has any ownership in the Maxsys or
      registration thereof, and InterQual acknowledges that use of the Maxsys

all materials and documents pertaining to the Maxsys.

      8.4 Termination and Sublicenses.

            8.4.1 Upon termination of this Agreement whether for cause or not
      for cause, whether voluntarily or involuntarily, the License shall be
      revoked effective on the date of termination and Licensee shall not enter
      into further Sublicenses. The sublicenses previously granted by Licensee

9. Confidential Information.

      9.1 Legal Restrictions. Neither party hereto shall be in default for
failure to supply information which such party, in good faith, believes cannot
be supplied due to prevailing law, or for supplying information which such
party, in good faith, believes is required to be supplied due to prevailing law.

      9.2   Non-Disclosure of Confidential Information.

            9.2.1 Each party acknowledges that (i) due to the nature of this
      Agreement, each party shall have access to and acquire Confidential
      Information as defined in Section 9.2.3 related to the business and
      operations of each other party; (ii) all Confidential Information
      constitutes confidential and proprietary information; (iii) the disclosure
      of Confidential Information to third parties would cause substantial loss
      to the goodwill of each party; (iv) disclosure of Confidential Information
      by each party shall be made due to the position of trust and confidence
      that each other party shall occupy due to the Agreement and due to the

      would cause the party owning the Confidential Information irreparable
      harm; and (vi) the restrictions imposed upon each party herein would not
      hamper it in doing business.

            9.2.2 In consideration of the acknowledgements set forth in Section

      this Agreement and following the termination of this Agreement, whether
      voluntarily or involuntarily, whether for cause or not for cause, hold any
      and all Confidential Information in the strictest confidence as a
      fiduciary, and shall not, voluntarily or involuntarily, sell, transfer,
      publish, disclose, display or otherwise make available to others any
      portion of the Confidential Information without the express written
      consent of the other party. Each party shall use its best efforts to
      protect the Confidential Information consistent with the manner in which
      it protects its most confidential business information; PROVIDED, HOWEVER,
      during the term of this Agreement and subsequent to the termination of

Criteria shall not be used by Licensee's Sublicensees for clinical
determinations to govern the level of medical care received by a patient or in

      or action against Licensee and its Sublicensees, for infringement of any
      patent, copyright or similar property right (including, but not limited
      to, misappropriation of trade secrets) based on any Criteria furnished
      hereunder by InterQual. InterQual shall have the sole right to conduct the
      defense of any such claim or action and all negotiations for its
      settlement or compromise, unless otherwise mutually agreed upon and

      expense, to either: (a) procure for Licensee the right to continue using

      InterQual and InterQual shall refund the then unearned portion of the

               such party, in good faith, believes is required to be supplied
               due to prevailing law.

               employees, agents, successors and assigns of each party) shall,
               during the term of this Agreement and following the termination

               practices or plans of each party, and all similar information of

        publicize the License of the Criteria to the Sublicensor in any
        advertising or publicity releases with the prior written approval of
        Sublicensor, which approval shall not be unreasonably withheld.

11.     Indemnification.

        11.1 Acknowledgements. Sublicensor acknowledges that InterQual has
        advised SubLicensor: (i) that the Criteria and the Criteria Manuals are
        based upon clinical interpretation and analyses (collectively
        "Analyses") and that the Analyses are secondary sources which alone
        cannot resolve medical ambiguities of particular situations or provide
        the sole basis for definitive decisions; (ii) that the Criteria or the
        Criteria Manuals should not be used for clinical determinations to
        govern the level of medical care received by a patient or in any manner
        interfere with the provider-patient relationship.

        11.2 Indemnity by Sub-Licensor. Sublicensor shall indemnify, defend and
        hold harmless InterQual, its officers, directors, employees and agents
        from any and all claims, suits, losses, demands, damages or expenses
        including reasonable attorneys' fees ("Liability") arising from any
        breach by Sublicensor of its express obligations hereunder.

        11.3   Indemnity by InterQual.

               11.3.1 InterQual shall indemnify, defend and hold harmless
        Sub-Licensor, its officers, directors, employees and agents from and
        against Liability arising from any breach by InterQual of its express
        obligations hereunder. InterQual assumes no Liability to SubLicensor or
        to any third party with respect to the Criteria, Criteria Manuals or
        Marks or other products sold or the services rendered by Sublicensor
        under or in connection therewith.

               11.3.2 THE CRITERIA AND CRITERIA MANUALS ARE PROVIDED "AS IS".
        EXCEPT FOR THE LIMITED WARRANTY TO REPAIR OR REPLACE AS SET FORTH IN
        SECTION 11.3.3 OF THIS AGREEMENT. INTERQUAL DISCLAIMS ANY OTHER
        WARRANTY, EXPRESS OR IMPLIED, INCLUDING AS TO MERCHANTABILITY AND
        FITNESS FOR A PARTICULAR PURPOSE OR SERVICE OF THE CRITERIA OR CRITERIA
        MANUALS, OR THE COMPLIANCE OF OUTPUT USING THE CRITERIA OR CRITERIA
        MANUALS WITH ANY LAW, REGULATION OR ORDER. IN NO EVENT

                                       5

        SHALL INTERQUAL, ITS SUBCONTRACTORS, OFFICERS, EMPLOYEES OR AGENTS BE
        LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
        CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR THE FURNISHING OF
        THE CRITERIA OR CRITERIA MANUALS OR PERFORMANCE OF SERVICES PROVIDED FOR
        HEREIN, EVEN IF ANY OF THEM HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH
        DAMAGES.

               11.3.3 InterQual shall defend at its own cost and expense any
        claim or action against Sublicensor and its Clients for infringement of
        any patent, copyright or similar property right (including, but not
        limited to, misappropriation of trade secrets) based on any Criteria or
        Criteria Manuals or modifications of the Criteria or Criteria Manuals
        furnished or approved hereunder by InterQual or based on Sublicensor's
        use thereof. InterQual shall have the sole right to conduct the defense
        of any such claim or action and all negotiations for its settlement or
        compromise, unless otherwise mutually agreed upon and expressed in
        writing signed by the parties hereto.

        If such infringement claim or action has occurred, or in InterQual's
        judgement is likely to occur, Sublicensor shall allow InterQual and
        InterQual shall, at InterQual's option and expense, either: (i) procure
        for Sublicensor and Licensees the right to continue using the alleged
        infringing Criteria and/or Criteria Manual(s), whichever is in question
        ("Infringing Criteria"); (ii) modify the Infringing Criteria to become
        non-infringing (provided that such modification does not adversely
        affect Sublicensor's or Licensees' intended use of the Criteria or
        Criteria Manual(s) as contemplated hereunder); (iii) replace the
        Infringing Criteria with equally suitable, compatible and functionally
        equivalent non-infringing Criteria or Criteria Manuals, whichever is in
        question, at no additional charge to Sublicensor or Sublicensees; or
        (iv) if none of the foregoing alternatives is reasonably available to
        InterQual, upon written request Sublicensor shall return the Infringing
        Criteria to InterQual and this Agreement shall automatically terminate.

        9 and Section 11; and (ii) accruing prior to termination.
