                                      LEASE



         THIS OFFICE LEASE (this "Lease"), made this 18th day of December, 1996,
by and between, RESURGENS PLAZA SOUTH ASSOCIATES, L.P., a Georgia limited
partnership ("Landlord") and SIMIONE CENTRAL, INC., a Georgia corporation, whose
principal place of business is 6600 Powers Ferry Road, Suite 300, Atlanta,
Georgia 30339, ("Tenant").

         1. PREMISES: Landlord, for and in consideration of the rents,
covenants, agreements and stipulations herein contained to be paid, kept and
performed by Tenant, has leased and rented, and by these presents does lease and
rent, unto Tenant and Tenant hereby leases, upon the terms and conditions set
forth herein, the Premises (also termed the "Leased Premises") located on the
first, second and third floors of that certain office building ("the Building")
situated on that certain tract of land ("the Land") located at 6600 Powers Ferry
Road, Atlanta, Georgia 30339. The Premises are more particularly shown on the
building floor plans annexed hereto as Exhibit "A" by this reference made a part
hereof. The total net rentable area of the Premises is deemed to be 55,553 net
rentable square feet (49,162 usable square feet). Effective March 1, 2001, the
area of the Premises shall become and be a total of 64,324 net rentable square
feet (56,924 usable square feet).

         2. TERM: The term of this lease (the "Term" or "Lease Term") shall be
for a period of sixty (60) months beginning on January 1, 1998 (the
"Commencement Date") and shall end on December 31, 2002 (the "Expiration Date")
unless sooner terminated as hereinafter set forth.

         3. RENTAL:

                  (a) Tenant shall and hereby agrees to pay to Landlord in
advance, without demand, deduction or set-off, annual rental of Eight Hundred
Forty-Nine Thousand Nine Hundred Sixty and 90/100 Dollars ($849,960.90) ("Base
Rental") in


<PAGE>   4


equal monthly installments of Seventy Thousand Eight Hundred Thirty and 00/100
Dollars ($70,830.00) on the first day of each month commencing with the month of
the Commencement Date. Base Rental and "Additional Rental" (as hereinafter
defined), are hereinafter together collectively called "Rental."

                  (b) Base Rental and "Additional Rental" (as hereinafter
defined) for any other fractional month shall be prorated in the same manner.
Base Rental and Additional Rental are herein collectively called "Rental."

                  (c) At each anniversary of the Commencement Date, during the
Term of this Lease, the then current Base Rental shall be increased by four
percent (4%). Adjustments in the Base Rental shall be made as of each and every
anniversary of the Commencement Date. Landlord shall, on or before the date when
the increase in Base Rental is due, furnish Tenant a statement reflecting the
adjustment of the Base Rental, which shall then remain in effect until the next
adjustment is made. Within ten (10) days following receipt of Landlord's
statement for each such adjustment, Tenant shall pay such increase in the Base
Rental as has accrued from the anniversary of the Commencement Date during the
period of the preparation of the statement.

                  (d) Tenant shall pay promptly when due all license, franchise,
and other fees or charges imposed on the business conducted by Tenant at the
Premises and shall pay all taxes levied or assessed upon Tenant's personal
property located at the Premises or upon improvements (whether classified as
personalty or realty) to the Premises made by Tenant or by Landlord at Tenant's
request. (Excluding improvements contemplated in this Lease). If some of the
improvements that Tenant is to pay taxes on are jointly assessed or taxed with
Landlord's improvements on the Building, Landlord shall determine that portion
of the taxes attributable to the improvements for which Tenant is responsible.
Following Landlord's determination, Landlord shall notify Tenant in writing and
Tenant shall pay Tenant shall pay Tenant's portion to Landlord on or before the
date specified in Landlord's notice. Within five (5) days of Landlord's request,
Tenant agrees to deliver to Landlord receipted tax bills showing payment of all



                                       2
<PAGE>   5


taxes required to be paid by Tenant hereunder. If Tenant fails to pay, either
thirty (30) days prior to delinquency, or, if applicable, when specified in
Landlord's notice, any taxes described above that are or may become a lien
against the Premises, Landlord shall have the right, but not the obligation, to
pay such taxes, together with associated fines, penalties and interest. Tenant
agrees to immediately reimburse to Landlord, as "Additional Rental", the amount
paid by Landlord, with interest from the date of Landlord's payment of same at a
rate of 18% per annum.

                  (e) Tenant recognizes that late payment of any Rental will
result in administrative expense to Landlord, the extent of which additional
expense is extremely difficult to ascertain. Tenant therefore agrees that if
Rental or any other sum due hereunder from Tenant to Landlord remains unpaid ten
(10) days after said amount is due, as set forth in Sections 3(c) and Section
3(d) hereof, the amount of such unpaid Rental or other sum shall be increased by
a late charge to be paid Landlord by Tenant in an amount equal to five percent
(5%) of the amount of Base Rental and/or Additional Rental or other sum then due
which shall be added to the Base Rental and/or Additional Rental or other sum
them due and shall be immediately due and payable.

         4. USE: The Premises shall be used as general office space in
connection with the operation of the Tenant's business and for no other purpose
whatsoever. Tenant shall, at its own cost and expense, procure and maintain each
and every permit, license, certificate or other authorization required in
connection with the lawful and proper use of the Premises by Tenant.

         5. INSURANCE: Tenant covenants and agrees that from and after the date
of delivery of the Premises from Landlord to Tenant, and during the Term of this
Lease or any renewal thereof, Tenant will carry and maintain, at its sole cost
and expense, the following types of insurance, in the amounts specified and in
the form hereinafter provided for:

<PAGE>   6

                  (a) Tenant shall keep in full force and effect Comprehensive
General Liability Insurance including Blanket Contractual, Personal Injury,
Broad Form Property Damage, Products Liability, Completed Operations, Fire,
Legal Liability, and Owned, Non-owned and Hired automobile coverages, naming

insureds as the case may be, with minimum limits of $1,000,000 combined single
limit for property damage and bodily injury per occurrence for any and all
claims for injury or damage to persons or property or for the loss of life or of
property occurring upon, in or about the Premises and the public portions of the
Building used by Tenant, its employees, agents, contractors, customers,
customers, and invitees. Tenant shall deposit a policy or policies of such
insurance, or an approved certificate thereof issued by duly authorized agents
of the carriers in question, with Landlord, at least ten (10) days before the
Commencement Date and each renewal of same and at least thirty (30) days prior
to the expiration of any existing policies. All such policies must provide that
Landlord and any additional insureds be provided with thirty (30) days prior
written notice of cancellation, reduction, or material change by the insurer.

                  (b) Tenant shall keep in full force and effect All Risk
insurance including sprinkler leakage and flood and earthquake (if flood and
earthquake exposure exists) and vandalism and malicious mischief on a 100%
replacement cost basis covering all contents, fixtures and improvements and such
other portions of the Premises which Landlord is not responsible for restoring.
Tenant shall deposit a policy or policies of such insurance, or an approved
certificate thereof with Landlord, providing Landlord with thirty (30) days
notice of cancellation, reduction, or material change by the insurer.

                  (c) Tenant shall keep in full force and effect Workers'
Compensation insurance as required by law and Employer's Liability coverage for
a minimum of $100,000 per occurrence.

                  (d) Tenant covenants to comply with any and all rules and
regulations applicable to the Premises issued by the Board of Fire Underwriters,
or by any other body



                                       4
<PAGE>   7

hereinafter constituted exercising similar functions, and of insurance companies
writing policies covering the Premises. Tenant shall pay all costs, expenses,
claims, fines, penalties and damages imposed because of failure of Tenant to
comply with this Paragraph 5(d) and agrees to indemnify Landlord from all
liability with reference thereto. Tenant shall, at its own cost and expense,
procure and maintain each and every permit, license, certificate or other
authorization and any renewals, extensions or continuances of the same required
in connection with lawful and proper use of the Premises for Tenant's business.
Tenant agrees to pay any increase in the amount of insurance premiums over and
above the rate now in force that may be caused by Tenant's use or occupancy of
the Premises. This payment shall be in addition to any amounts due Landlord
pursuant to other provisions in this Lease.

                  (e) Carrying the prescribed insurance will in no way be
construed as either a limitation or satisfaction of any hold harmless or
indemnity agreements contained in this Lease.

                  (f) Landlord and Tenant shall each have included in all
policies of insurance respectively obtained by them with respect to the Building
and/or the Premises a waiver by the insurer of all right of subrogation against
the other in connection with any loss or damage thereby insured against. So long
as both Landlord's and Tenant's policies then in force include such mutual
waiver of subrogation, Landlord and Tenant, to the fullest extent permitted by
law, each release the other from liability for loss or damage to the extent such
loss or damage is covered by valid and collectible insurance in effect at the
time of such loss or damage. If such waiver of subrogation shall not be
obtainable or shall be obtainable only at a premium over that chargeable without
such waiver, the party seeking such waiver shall notify the other thereof in
writing, and the latter shall have ten (10) days in which either (i) to procure
on behalf of the notifying party insurance with such waiver from a company or
companies reasonably satisfactory to the notifying party or (ii) to agree to pay
such additional premium (in Tenant's case, in the proportion which the rentable
area of the Premises bears to the area covered by the insurance policy of
Landlord in question).

conclusively deemed to have accepted the Premises in their "as is" condition as

forth in Paragraph 4 hereof.

         7. REPAIRS: Tenant, at its expense, shall promptly make such repairs as

<PAGE>   10

                  (e) An involuntary petition is filed against Tenant or such

remedies available to Landlord under the laws of the State of Georgia;

                  (a) Landlord may terminate this Lease. Upon termination,
Tenant shall immediately surrender the Premises to Landlord. If tenant fails to
do so, Landlord may, without prejudice to any other remedy Landlord may have
either by law or under this Lease, enter upon the Premises and remove or expel
Tenant and Tenant's personal property with or without force and without being
liable to Tenant in any manner whatsoever for damages therefor. Upon
termination, Tenant shall pay to Landlord (but not on lieu of any other damages
to which Landlord may be entitled), the unamortized cost of all work performed
on the Premises by Landlord in preparing the Premises for occupancy by Tenant.

                  (b) Landlord may enter the Premises and remove Tenant and its
personal property, by force if necessary, without being liable to Tenant in any
manner whatsoever for such acts, and may relet the Premises as agent of Tenant
and receive such rent therefor. In no event however, shall Landlord be liable in
any way whatsoever for its



                                       8
<PAGE>   11

failure or refusal to relet the Premises or any part thereof. Tenant shall
remain liable to Landlord for any deficiency which may arise by reason of such
reletting but shall not be entitled to any surplus so arising, except for any
surplus remaining at the end of the stated Term hereof.

         If this Lease is terminated by Landlord, Tenant shall pay to Landlord
as additional damages (and not in lieu of any other damages to which Landlord
may be entitled), the unamortized cost of all work performed on the Premises by
Landlord in preparing the Premises for occupancy by Tenant and at the election
of Landlord:

                  (i)  a sum which represents the then excess, if any, of (A)
the aggregate amount of the Rental due and reserved hereunder from the date of
Tenant's default to the Expiration Date of the fully stated Term hereof over (B)
the aggregate rental value of the Premises for the same period as reduced by the
estimated cost of reletting the Premises, including attorney's fees,
commissions, alterations and repair costs; or

                  (ii) sums equal to the Rental which would have been payable by
Tenant had this Lease not been so terminated, or had Landlord not so re-entered
the Premises; payable upon the due dates therefor specified herein, provided,
however, that if Landlord shall relet the Premises during said period, Landlord
shall credit Tenant with the net rents received by Landlord from such reletting,
such net rents to be determined by first deducting from the gross rents as and
when received by Landlord from such reletting, the expenses incurred or paid by
Landlord in terminating this Lease and/or in re-entering the Premises and in
securing possession thereof, as well as the expenses of reletting, including,
without limitation, altering and preparing the Premises for new tenants,
brokers' commissions, legal fees, and all other expenses chargeable against the
Premises and the rental therefrom, it being understood that any such reletting
may be for a period shorter or longer than the remaining Term of this Lease; but
in no event shall Tenant be entitled to a credit for any net rents from a
reletting, except to the extent set forth hereinabove.



                                       9
<PAGE>   12

         If Landlord shall not be permitted to terminate this Lease as
hereinabove provided because of the provisions of Title 11 of the United States
Code relating to Bankruptcy as amended (the "Bankruptcy Code"), then Tenant or
any trustee for Tenant agrees promptly, within no more than fifteen (15) days
upon request by Landlord to the Bankruptcy Court, to assume or reject this
Lease. In such event, Tenant or any trustee of Tenant may assume this Lease only
if it (i) cures or provides adequate assurance that the trustee will promptly
cure any default hereunder, and (ii) compensates or provides adequate assurance
that Tenant will promptly compensate Landlord for any actual pecuniary loss to
Landlord resulting from Tenant's default. See Special Stipulation No. 2.

         13. LIABILITY: Neither Landlord nor any of its partners or affiliates,
individual, corporate or other, shall have any personal liability with respect
to its obligations under this Lease. Tenant agrees to look solely to Landlord's
interest in the Building and Land for satisfaction of Tenant's remedies.

         14. NO ESTATE: This Lease shall create the relationship of landlord and
tenant between the parties. No estate shall pass out of Landlord, and Tenant
shall have only a usufruct which is not subject to levy and sale.

         15. SERVICES: So long as Tenant is not in default hereunder, Landlord
shall provide the following services to the Premises:

                  (a) Landlord shall provide routine janitorial services to the
Premises;

                  (b) Landlord shall furnish electrical service for the lighting
of the Premises to building standard light level produced by building standard
fluorescent lighting fixtures and lamps provided by Landlord and for usual and
normal small office machines and equipment utilizing 110 volt current; and



                                       10
<PAGE>   13

                  (c) Landlord shall furnish seasonable air conditioning and
heating from 8:00 a.m. to 6:00 p.m. Monday through Friday and 9:00 a.m. to 1:00
p.m. on Saturdays, national holidays excepted.

         Landlord reserves the right to prohibit the installation of additional
lighting fixtures, heat generating equipment, data processing machines, etc.,
unless and until arrangements acceptable to Landlord are made by Tenant to
install supplementary air conditioning equipment on the Premises at Tenant's
cost and expense. The costs of maintaining and repairing such additional
lighting, equipment, machines and supplementary air conditioning equipment shall
be paid by Tenant directly to the applicable servicing company and the costs of
operating such equipment shall be paid as Additional Rental by Tenant with the
monthly installations of Base Rental due hereunder at such reasonable rates as
are established by Landlord.

         Should Tenant desire either heating air conditioning at times when such
services are not furnished by Landlord under the terms of this Lease, Landlord
may, but shall not be required to, furnish such services as requested by Tenant,
at Tenant's expense and at such hourly charge as is from time to time determined
by Landlord. Landlord shall not be liable for any damages directly or indirectly
resulting from the interruption or curtailment of services referred to in this
Paragraph 15 nor for the interruption in use of any equipment in connection with
the furnishing of such services. Landlord reserves the right, in addition to
Landlord's other rights and remedies hereunder and at law or in equity, to
discontinue furnishing said services upon five (5) days written notice so long
as Tenant shall be and remain in default hereunder.

         16. ASSIGNMENT AND SUBLETTING:

                  (a) Tenant shall not sublet the Premises or any part thereof
         nor assign, mortgage, pledge or encumber this Lease or any interest
         therein, without the prior written consent of Landlord, which consent
         Landlord may refuse, withhold, delay and/or condition in its sole and
         absolute discretion.



                                       11
<PAGE>   14

                  (b) Any transfer of effective control of Tenant or any other
         transfer of this Lease from Tenant by merger, consolidation,
         liquidation by operation of law or otherwise without the prior written
         consent of Landlord shall be deemed a violation of this Paragraph 16.
         Tenant shall not permit any business to be operated in or from the
         Premises by any concessionaire or licensee without the prior written
         consent of Landlord.

                  (c) Any consent by Landlord to any assignment or subletting,
         or to the operation by a concessionaire or licensee, shall not
         constitute a waiver of the necessity for such consent to any subsequent
         assignment or subletting, or operation by a concessionaire of licensee.
         See Special Stipulation No. 4.

         17. CONDEMNATION AND EMINENT DOMAIN: In the event the whole or any part
of the Premises shall be taken or condemned by any competent authority for any
public or quasi-public use or purpose, or acquired by private purchase in lieu
of condemnation, this Lease shall terminate from the date when the possession of
the part so taken shall be required for such use or purpose, and the entire
amount of the condemnation award attributable to such taking or condemnation
shall be paid to Landlord. Tenant shall have no right in and to such award or
any portion thereof, such right, if any, being hereby expressly waived by
Tenant.

         18. ALTERATIONS AND IMPROVEMENTS:

                  (a) Tenant shall make no alterations, additions or
improvements to any part of the Premises without the prior written consent of
Landlord, which shall not be unreasonably withheld. Landlord may impose those
conditions to its consent that Landlord deems appropriate, including, without
limitation, a requirement that a contractor or workman of Landlord's choice
perform all work required in connection with such alteration, addition, or
improvement and that, prior to the commencement of any work, Tenant pay all
anticipated costs to Landlord for later disbursement to said contractor. All
alterations, additions, or improvements (or any part of them), whether



                                       12
<PAGE>   15

temporary or permanent in nature (except only movable office furniture or
equipment) shall, at the option of Landlord, become the property of Landlord
without compensation to Tenant, and be surrendered with the Premises at the
expiration or termination of this Lease. Notwithstanding any of the foregoing,
Landlord may require Tenant to remove such alterations or additions (or any part
of them) at the termination of this Lease. Tenant agrees to indemnify and hold
Landlord and the Premises fee from any liability, claim, lien, encumbrance or
judgement created or suffered in connection with any labor, services, or
materials relating to such alterations, additions or improvements. Tenant shall
require all contractors, subcontractors, materials suppliers rendering services
or materials to the Premises, to furnish to Landlord prior to entering the
Premises a waiver and release of all liens and privileges that may exist or
arise for work done, all labor performed, and all materials furnished under any
contract. In the event that any such waiver and release is not furnished as
required, Landlord shall have the right to order the immediate cessation of any
work being performed in the Premises by such contractors or material suppliers.
Notwithstanding anything hereinabove to the contrary, Tenant shall have no
obligation to remove any of the alterations or improvements constructed as a
part of the initial Tenant improvements and Tenant shall not be required to
remove any future leasehold improvements in the premises unless Landlord
notifies Tenant in writing at the time Landlord approves the plans for such
leasehold improvement, that some or all of such improvements will have to be
removed upon the expiration of this Lease or any renewal thereof.

                  (b) Tenant shall neither cut, drill into, disfigure, deface or
injure any part of the Building, nor obstruct or permit any obstruction,
alteration, addition, improvement, or installation in the Premises or the
Building without first obtaining the written consent of the Landlord.

         19. ATTORNEY'S FEES: Tenant agrees to pay all reasonable attorney's
fees and expenses Landlord incurs in enforcing any of the obligations of Tenant
under this Lease, or in any litigation or negotiation in which Landlord shall,
without its fault,



                                       13

become involved through or on account of this Lease. These provisions shall
survive the termination of this Lease.
See Special Stipulation No. 7.

         20. ENTIRE AGREEMENT: This Lease contains the entire agreement of the
parties and no representations or agreements, oral or otherwise, between the
parties not embodied herein shall be of any force or effect. No failure of
Landlord to exercise any power given Landlord hereunder, or to insist upon
strict compliance by Tenant of any obligation hereunder, and no custom or
practice of the parties at variance with the terms hereof shall constitute a
waiver of Landlord's right to demand exact compliance with the terms hereof.

         21. TIME OF ESSENCE: Time is of the essence of Tenant's obligations
under this Lease.

         22. RULES AND REGULATIONS: The Rules and Regulations attached hereto as

reason whatsoever, Tenant shall surrender the Premises and keys thereof to
Landlord broom clean and in the same condition as on the Commencement Date,
natural wear and tear only excepted, with all personal property of Tenant
removed therefrom, subject to the provisions of Paragraph 18. If Tenant fails to
remove any personalty from the Premises upon the termination of this Lease,
Landlord may dispose of or store the same at its election without liability to
Tenant for loss thereof and Tenant shall be liable to Landlord for the expense
of such removal, disposal and/or storage. Should Tenant refuse or fail to
surrender the premises upon the expiration of the Lease Term or earlier
termination thereof, Tenant shall be a tenant at sufferance and shall pay to
Landlord on
