                                    SUBLEASE

1.     PARTIES

       This Sublease dated this 22 day of November, 1996, is made between
       ENVIRONMENTAL DESIGN INTERNATIONAL, LTD.("Sublessor") and SIMIONE
       CENTRAL, INC.("Sublessee").

2.     MASTER LEASE

       Sublessor is the lessee under a written lease dated December 8, 1993,
       wherein Resurgens Plaza South Associates, L.P. ("Lessor") leased to
       Sublessor the real property located in the City of Atlanta, County of
       Fulton, State of Georgia, described as Suite 200, 6600 Powers Ferry Road,
       Atlanta, Georgia 30339. Said lease is herein referred to as the "Master
       Lease" and is attached hereto as Exhibit "A".

3.     PREMISES

       Sublessor hereby subleases to Sublessee on the terms and conditions set
       forth in this Sublease the entire portion of the Master Premises
       ("Premises") consisting of 8,771 rentable square feet as depicted on
       Exhibit "B" attached hereto.

4.     WARRANTY BY SUBLESSOR

       Sublessor warrants and represents to Sublessee that the Master Lease has
       not been amended or modified that Sublessor is not now, and as of the
       commencement of the Term hereof will not be, in default or breach of any
       of the provisions of the Master Lease, and that Sublessor has no
       knowledge of any claim by Lessor that Sublessor is in default or breach
       of any of the provisions of the Master Lease.

5.     TERM

       5.1    The Term of this Sublease shall commence on March 1, 1997 and end
              on February 28, 2001, unless otherwise sooner terminated in
              accordance with the provisions of this Sublease. Possession of the
              Premises ("Possession") shall be delivered to Sublessee on the
              commencement of the Term and the Premises shall be in
              substantially the same condition as they are in as of the date of
              this Sublease. If for any reason Sublessor does not deliver
              Possession to Sublessee on the commencement of the Term, or same
              are not in the condition set forth above, Sublessor shall not be
              subject to any liability for such failure, the Termination Date
              shall not be extended by the delay, and the validity of this
              Sublease shall not be impaired, but rent shall abate until
              delivery of Possession in the condition set forth above.
              Notwithstanding the


<PAGE>   2

              foregoing, if Sublessor has not delivered Possession in the
              condition set forth above to Sublessee on or before April 1, 1997,
              then at any time thereafter and before such delivery of
              Possession, Sublessee may give written notice to Sublessor of
              Sublessee's intention to cancel this Sublease. Said notice shall
              set forth an effective date for such cancellation which shall be
              at least ten (10) days after delivery of said notice to Sublessor.
              If Sublessor delivers such Possession to Sublessee on or before
              such effective date, this Sublease shall remain in full force and
              effect. If Sublessor fails to deliver such possession to sublessee
              on or before such effective date, then, at the option of
              Sublessee: (a) this Sublease shall be canceled, in which case all
              consideration previously paid by Sublessee to Sublessor on account
              of this Sublease shall be returned to Sublessee, this Sublease
              shall thereafter be of no further force or effect, and Sublessor
              shall have no further liability to Sublessee on account of such
              delay or cancellation; or (b) Sublessee may take whatever actions
              and remedies it is entitled to at law and/or equity. If Sublessor
              permits Sublessee to take Possession prior to the commencement of
              the Term, such early Possession shall not advance the Termination
              Date and shall be subject to the provisions of this Sublease
              including, without limitation, the payment of rent.

       5.2    Subject to the prior written consent of Sublessee, Lessor may
              terminate the Master Lease at any time during the Term. In the
              event of any termination of this Sublease under the provisions of
              this, paragraph 5.2, the Sublease shall, after the termination, be
              of no further force or effect and, except as set forth in this,
              paragraph 5.2, Sublessee shall have no further liability to
              Sublessor on account of this Sublease or any matters related
              thereto.

6.     RENT

       Sublessee shall pay to Lessor as minimum rent, without deduction, set
       off, notice or demand at the office of Lessor, the sum set forth below,
       per month, in advance, on the first day of each month of the Term. If the
       Term begins or ends on a day other than the first or last day of the
       month, the rent for the partial month shall be prorated on a per diem
       basis.

       March 1997 to February 1998     9,352.04
       March 1998 to February 1999    10,082.96
       March 1999 to February 2000    10,813.87
       March 2000 to February 2001    11,544.79

       In addition to the above, Sublessee shall also pay to Lessor Additional
       Rental and all other sums due Lessor under the Master Lease during the
       Term to the extent that such Additional Rent is applicable to the
       Premises and the Term.

7.     USE OF PREMISES

       The Premises shall be used and occupied only for general office purposes
       and for no other use or purpose.

8.     ASSIGNMENT AND SUBLETTING

       Sublessee shall not assign this Sublease or further sublet all or any
       part of the Premises without the prior written consent of Sublessor,
       which consent shall not be unreasonably withheld (and the consent of
       Lessor, if such is required under the terms of the Master Lease).
       Notwithstanding anything to the contrary, however, Sublessee shall have
       the right to sublet or assign all or any part of the Premises to any
       entity with which Sublessee is related through full or partial common
       control, ownership or management.

9.     OTHER PROVISIONS OF SUBLEASE

       All applicable terms and conditions of the Master Lease are incorporated
       into and made a part of this Sublease as if Sublessor were the lessor
       thereunder, Sublessee the lessee thereunder, and the Premises the Master
       Premises, except for the rental amounts stipulated herein. Sublessee
       assumes and agrees to perform the lessee's obligations under the Master
       Lease during the Term to the extent that such obligations are applicable
       to the Premises and the Term. Neither Sublessor nor Sublessee shall
       commit or suffer any act or omission that will violate any of the
       provisions of the Master Lease. Sublessor shall exercise due diligence in
       attempting to cause Lessor to perform its obligations under the Master
       Lease for the benefit of Sublessee. If the Master Lease terminates, this
       Sublease shall terminate and the parties shall be relieved of any further
       liability or obligation under this Sublease, provided however, that if
       the Master Lease terminates as a result of a default or breach by
       Sublessor or Sublessee under this Sublease and/or the Master Lease, then
       the defaulting party shall be liable to the non-defaulting party for the
       damage suffered as a result of such termination.

       It is expressly understood and agreed, however, that Sublessor is not in
       the position to render any of the services or to perform any of the
       obligations required of Sublessor by the terms of this Sublease which are
       the responsibility of the Lessor under the Master Lease, and that
       performance by Sublessor of its obligations hereunder is conditioned upon
       due performance by Lessor of its corresponding obligations under the
       Master Lease. It is further understood and agreed, therefore, that
       notwithstanding anything to the contrary contained in this Sublease,
       Sublessor shall not be in default under this Sublease for failure to
       render such services or perform such obligations required of Sublessor by
       the terms of this Sublease which are the responsibility of the Lessor
       under the Master Lease, but Sublessor agrees to exercise due diligence
       to insure that Lessor performs said obligations as above provided. The
       terms "due diligence" shall not include legal action against Lessor for
       its failure to so perform unless Sublessee agrees to pay all costs and
       expenses incurred in connection therewith.
