4.       WARRANTY BY SUBLESSOR AND SUBTENANT #1.
         Sublessor and Subtenant #1 warrant and represent to Subtenant #2 that
         the Master Lease has not been amended or modified except as expressly
         set forth herein, that Sublessor and Subtenant #1 are 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
         and Subtenant #1 have no knowledge of any claim by Lessor the Sublessor
         or Subtenant #1 are in default or breach of any of the provisions of
         the Master Lease or Sublease.

5.       TERM.
         The Term of this Sub-Sublease shall commence on September 8, 1997
         ("Commencement Date"), or when Lessor consents to this Sub-Sublease (if
         such consent is required under the Master Lease), whichever shall last
         occur, and end on November 30, 1998 ("Termination Date"), unless
         otherwise sooner terminated in accordance with the provisions of this
         Sub-Sublease. In the event the Term commences on a date other than the
         Commencement Date, Sublessor, Subtenant #1 and Subtenant #2 shall
         execute a memorandum setting forth the actual date of commencement of
         the Term. Possession of the Premises ("Possession") shall be delivered
         to Subtenant #2 on the commencement of the Term. If for any reason
         Subtenant #1 does not deliver Possession to Subtenant #2 on the
         commencement of the Term, Subtenant #1 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 Sub-Sublease shall not be
         impaired, but rent shall abate until delivery of Possession.
         Notwithstanding the foregoing, if Subtenant #1 has not delivered
         Possession to Subtenant #2 within ten (10) days after the Commencement
         Date, then at any time thereafter and before delivery of Possession,
         Subtenant #2 may give written notice to Subtenant #1 of Subtenant #2's
         intention to cancel this Sub-Sublease. Said notice shall set forth an
         effective date for such cancellation which shall be at least three (3)
         days after delivery of said notice to Subtenant #1. If Subtenant #1
         delivers Possession to Subtenant #2 on or before such effective date,
         this Sub-Sublease shall remain in full force and effect. If Subtenant
         #1 fails to deliver Possession to Subtenant #2 on or before such
         effective date, this Sub-Sublease shall be canceled, in which case all
         consideration previously paid by Subtenant #2 to Subtenant #1 on
         account of this Sub-Sublease shall be returned to Subtenant #2, this
         Sub-Sublease shall thereafter be of no further force or effect, and
         Subtenant #1 shall have no further liability to Subtenant #2 on account
         of such delay or cancellation. If Subtenant #1 permits Subtenant #2 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 Sub-Sublease, including without limitation
         the payment of rent.

6.       RENT.
         6.1 Minimum Rent. Subtenant #2 shall pay to Subtenant #1 as minimum
         rent, without deduction, setoff, notice, or demand, at 1901 Montreal

                                       1
   2

         or at such other place as Subtenant #1 shall designate from time to
         time by notice to Subtenant #2, the sum of Five Thousand Three Hundred
         Thirty-Two and 71/100 Dollars ($5,332.71) per month, in advance on the
         first day of each month of the Term. Subtenant #2 shall pay to
         Subtenant #1 upon execution of this Sub-Sublease Five Thousand Three
         Hundred Thirty-Two and 71/100 Dollars ($5,332.71) as rent for September
         1997. 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. Additional provisions: Rent commencement will begin
         September 8, 1997.

7.       SECURITY DEPOSIT.
         On the date of execution of this Sub-sublease by Subtenant #2,
         Subtenant #2 will pay to Subtenant #1 a security deposit in the amount
         of $5,332.71 for Subtenant #2's faithful performance of Subtenant #2's
         obligation hereunder (hereinafter "Security Deposit"). If Subtenant #2
         fails to pay rent or other charges when due under this Sub-sublease, or
         fails to perform any of its other obligations hereunder, Subtenant #1
         may use or apply all or any portion of the Security Deposit for the
         payment of any rent or other amounts then due hereunder and unpaid, for
         the payment of any other sum for which Subtenant #1 may become
         obligated by reason of Subtenant #2's default or breach, or for any
         loss or damage sustained by Subtenant #1 as a result of Subtenant #2's
         default or breach. If Subtenant #1 so uses any portion of the Security
         Deposit, Subtenant #2 shall, within (10) days after written demand by
         Subtenant #1, restore the Security Deposit to the full amount
         originally deposited, and Subtenant #2's failure to do so shall
         constitute a default under this Sub-sublease. Subtenant #1 shall not be
         required to keep the Security Deposit separate from its general
         accounts, and shall have no obligation or liability for payment of
         interest on the Security Deposit. In the event Subtenant #1 assigns its
         interest in this Sub-sublease, Subtenant #1 shall deliver to its
         assignee so much of the Security Deposit as is then held by Subtenant
         #1. Within ten (10) days after the Term has expired, or Subtenant #2
         has vacated the Premises, or any final adjustment pursuant to Paragraph
         5(b) hereof has been made, whichever shall last occur, and provided
         Subtenant #2 is not then in default of any of its obligations
         hereunder, the Security Deposit, or so much thereof as had not
         theretofore been applied by Subtenant #1, shall be returned to
         Subtenant #2 or to the last assignee, if any, of Subtenant #2's
         interest hereunder.

8.       USE OF PREMISES.
         The Premises shall be used and occupied only for general office
         purposes, and for no other use or purpose.

9.       ASSIGNMENT AND SUBLETTING.
         Subtenant #2 shall not assign this Sub-Sublease or further sublet all
         or any part of the Premises without the prior written consent of
         Sublessor and Subtenant #1 which consent shall not be unreasonably
         withheld (and the consent of Lessor, if such is required under the term
         of the Master Lease).

10.      OTHER PROVISIONS OF SUB-SUBLEASE.
         All applicable terms and conditions of the Master Lease are
         incorporated into and made a part of this Sub-Sublease as if Sublessor
         were the lessor thereunder, Subtenant #1 the lessee thereunder,
         Subtenant #2 the sublessee thereunder, and the Premises the Master
         Premises. Subtenant #2 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, except that the
         obligation to pay rent to Lessor under the Master Lease shall be
         considered performed by Subtenant #2 to the extent and in the amount
         rent is paid to Subtenant #1 in accordance with Section 6 of this
         Sub-Sublease. Subtenant #2 shall not commit or suffer any act or
         omission that will violate any of the provisions of the Master Lease.
         Sublessor and Subtenant #1 shall exercise due diligence in attempting
         to cause Lessor to perform its obligations under the Master Lease for
         the benefit of Subtenant #2. If the Master Lease terminates, this
         Sub-Sublease shall terminate and the parties shall be relieved of any
         further liability or obligation under this Sub-Sublease, provided
         however, that if the Master Lease terminates as a result of a default
         or breach by Sublessor, Subtenant #1 or Subtenant #2 under this
         Sublease, Sub-Sublease and/or the Master Lease, then the defaulting
         party shall be liable to the nondefaulting party for the damage
         suffered as a result of such termination. Notwithstanding the
         foregoing, if the Master Lease gives Sublessor, or Subtenant #1 any
         right to terminate the Master Lease in the event of the partial or
         total damage, destruction, or condemnation of the Master Premises or
         the building or project of which the Master Premises are a part, the
         exercise of such right by Sublessor or Subtenant #1 shall not
         constitute a default or breach hereunder.

         * Except as specifically set forth within this Sub-Sublease. This
         Sub-Sublease is not to be construed as an amendment to the Lease
         Agreement in any report.

                  due to the failure of Tenant to fulfill any obligation
                  pursuant to the terms of this Lease or any Exhibit thereto,
                  including without limitation Tenant's failure to comply with
                  the Plan Delivery Date described in section 1.4, the Lease
                  shall be deemed to have commenced upon the Lease Commencement

                  rights and obligations of the parties shall terminate.

         be required to spend or incur by reason of Tenant's default, or any
         other sum which Landlord may in its reasonable discretion deem
         necessary to spend or incur by reason of Tenant's default. In such
         event, Tenant shall upon demand deposit with Landlord the amount so

                  any cause whatsoever or from failure to make any repairs or
                  perform any maintenance. No temporary interruption or failure
                  of such services incident to making of repairs, alterations,

                                     not exceed expected savings In Operating
                                     Costs resulting from such capital

         lease Year. If such costs for any Calendar Lease Year exceed Estimated
         Costs Allocable to the Premises paid by Tenant to Landlord pursuant to
         the preceding Section 8.3, then the amount of such overpayment by
         Tenant shall be credited by Landlord to the next month's Rent payable
         by Tenant.

         day of a Year, the amount of any adjustment between Estimated Costs

         termination occurs shall be prorated on the basis which the number of
         days from the commencement of such Year in which such termination
         occurs to and Including such termination date bears to 365; and any
         amount payable by Landlord to Tenant or Tenant to Landlord with respect
         to such adjustment shall be payable within thirty (30) days after
         delivery by Landlord to Tenant of the statement of Actual Cost
         allocable to the Premises with respect to such Partial Year.

8.7      Further Adjustment: In the event the average occupancy level of the
         Building in any Lease Year was not ninety-five percent (95%) or more of
         full occupancy, then in making the calculations in 8.3 and 8.4 the
         Estimated Costs and Actual Costs for such year shall be proportioned
         among the Tenants by the Landlord to reflect those costs which would
         have occurred had the Building been ninety-five percent (95%) occupied
         during such year.

8.8      Base Year: Notwithstanding anything to the contrary in this Section 8
         or in Section 9, the Rent payable by Tenant shall in no event be less
         than the Rent specified in Section 1.7 of this Lease.

8.9      Non-Payment of Additional Rent: In the event of non-payment of the
         Additional Rent hereunder, Landlord shall have the same rights with
         respect to such non-payment of Rent hereunder.

                  directly to the taxing authority; charges and assessments
                  levied with respect to the Land, the Building, any

         plans and specifications for Tenant's improvements of a nature commonly
         found on a "punch list" (as that term is used in the construction
         industry), Tenant shall promptly notify Landlord of such deviations.
         The existence of such punch list items shall not postpone the
         Commencement Date of this Lease nor the obligation of Tenant to pay
         Rent.

         cost of making all special improvements requested by Tenant, including

         other attachments hereto as being furnished by Landlord; provided,
         however, Tenant shall not be obligated to pay for the cost of any

         upon the Premises at all reasonable times for the purpose of inspecting
         the Premises or for the purpose of cleaning, repairing, altering or
         improving the Premises or the Park. Nothing contained in this Section
         14 shall be deemed to impose any obligation upon the Landlord not
         expressly stated elsewhere in this Lease. When reasonably necessary
         Landlord may temporarily close entrances, doors, corridors, elevators
         or other facilities without liability to Tenant by reason of such
         closure and without such action by Landlord being construed as an
         eviction of Tenant or release of Tenant from the duty of observing and
         performing any of the provisions of this Lease. Provided, however, that
         such interference is such as to cause the premises to be untenantable
         and such interference continues for a period of more than fifteen (15)
         consecutive business days, then rent shall abate beginning on the
         fifteenth (15th) day. Landlord shall have the right to enter the
         Premises with prior written notice for the purpose of showing the

                  untenantable, (either wholly or in part) by fire or other
                  casualty, Landlord may, at its option, restore the Premises to
                  their previous condition, and in the meantime the monthly Rent
                  shall be abated I n the same proportion as the untenantable
                  portion of the Premises bears to the whole thereof, and this
                  Lease shall continue in full force and effect. If the damage
                  is due directly or indirectly, to the willful misconduct of
                  Tenant, or its officers, contractors, licensees, agents,
                  servants, employees, guests, invitees or visitors, there shall
                  be no abatement of Rent except to the extent Landlord receives

                  Landlord for loss of Rent.

         15.2     Termination for Material or Uninsured Damages: If the Building
                  shall be destroyed or damaged by fire or other casualty

                  (10%) thereof is rendered untenantable or in the case the
                  Building shall be materially destroyed or damaged by any other
                  casualty other than those covered by such Insurance policy,
                  notwithstanding that the Tenant Premises may be unaffected
                  directly by such destruction or damage, Landlord may at its
                  election, with prior written consent of any first mortgagee,
                  terminate this Lease by notice In writing to Tenant within
                  sixty (60) days after such destruction or damage. Such notice
                  shall be effective thirty (30) days after receipt thereof by
                  Tenant.

         15.3     Business Interruption: Other than rental abatement provided in
                  Section 15.1 no damages, compensation or claim shall be
                  payable by Landlord for inconvenience or loss of business
                  arising from interruption of business, repair or restoration
                  of the Building or Premises. Landlord shall use its best

         undertakings and agreements or for the purpose of binding Landlord
         personally or the assets of Landlord except Landlord's interest in the
         Premises and Park, but are made and intended for the purpose of binding
         only the Landlord's interest in the Premises and Park, as the same way,
         from time to time, be encumbered. No personal liability or personal
         responsibility is assumed by, nor shall at any time be asserted or
         enforceable against Landlord or its partners or their respective heirs,
         legal representatives, successors and assigns on account of the Lease
         or on account of any covenant, or undertaking or agreement of Landlord
         contained in this Lease.

32.      WAIVER OF JURY TRIAL:

         TO THE EXTENT PERMITTED BY LAW, IT IS MUTUALLY AGREED BY AND BETWEEN
         LANDLORD AND TENANT THAT THE RESPECTIVE PARTIES HERETO SHALL, AND THEY
         DO HEREBY, WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
         COUNTERCLAIM BROUGHT BETWEEN THE PARTIES HERETO OR THEIR SUCCESSORS OR
         ASSIGNS ON ANY MATTERS ARISING OUT OF, OR IN ANY WAY CONNECTED WITH,
         THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, AND/OR TENANT'S
         USE OF, OR OCCUPANCY OF, THE PREMISES. TENANT FURTHER AGREES THAT IT
         SHALL NOT INTERPOSE ANY COUNTERCLAIM OR COUNTERCLAIMS IN A SUMMARY
         PROCEEDING OR IN ANY ACTION BASED UPON NON-PAYMENT OF RENT REQUIRED BY
         TENANT HEREUNDER. THIS WAIVER IS MADE FREELY AND VOLUNTARILY, WITHOUT
         DURESS AND ONLY AFTER EACH OF THE PARTIES HERETO HAS HAD THE BENEFIT OF
         ADVICE FROM LEGAL COUNSEL ON THIS SUBJECT.

33.      ESTOPPEL CERTIFICATES: Tenant shall, from time to time, upon written
         request of Landlord, execute, acknowledge and deliver to Landlord or
         its designee a written statement stating: the date this Lease was
         executed and the date it expires; the date Tenant entered into
         occupancy of the Premises; the amount of minimum monthly rent and the
         date to which such rent has been paid; and certifying the following:
         that this Lease is In full force and effect and has not been assigned,
         modified, supplemented or amended in any way (or specifying the date
         and terms of agreement so affecting this Lease); that this 

   16

         Lease represents the entire agreement between the parties as to this
         leasing; that all conditions under this Lease to be performed by the
         Landlord have been satisfied, including but without limitation, all
         co-tenancy requirements, if any; that all required contributions by
         landlord to Tenant on account of Tenant's improvements have been
         received; that on this date there are no existing defenses or offsets

         Landlord; that no Rent has been paid more than one month in advance;
         and that no security has been deposited with Landlord (or, is so, the
         amount thereof). It is intended that any such statement delivered
         pursuant to this paragraph may be relied upon by a prospective
         Purchaser of Landlord's interest or assignee of any mortgage upon
         Landlord's Interest in the Park. Failure by Tenant to respond within
         ten (10) days of receipt by Tenant of a written request by Landlord as

         the part of Landlord accruing from and after the date of such transfer,
         and Tenant agrees to attorn to the transferee.

         than Rent and Additional Rent required to be paid by it hereunder or
         shall fail to perform any other act on its part to be performed
         hereunder, and such failure shall continue for ten (10) days after
         written notice thereof by Landlord, Landlord may, but shall not be
         obligated so to do, and without waiving or releasing Tenant from any
         obligations of Tenant, make any such payment or perform any such other
         act on Tenant's part to be made or performed as provided in this Lease.
         Landlord shall have (in addition to any other right or remedy of
         Landlord) the same rights and -remedies in the event of the non-payment
         of sums due under this Section as in the case of default by Tenant in
         the payment of Rent.

36.      SUBSTITUTED PREMISES: In the event Premises rented to Tenant are less
         than 7,000 square feet in area, Landlord reserves the right, at its
         option and upon giving thirty (30) days written notice in advance to
         the Tenant, to transfer and remove the Tenant from Premises to any
         other available rooms and offices of substantially equal size and area
         and equivalent rental in the Building of which Premises are a part, or
         other buildings within the Pa Landlord shall bear the expense of said
         removal including, but not limited to, cost of moving, telephone cable
         installation, computer cable, and stationery replacement costs, as well
         as the expense of any renovations or alterations necessary to make the
         new space substantially conform in layout and appointment with the
         original Premises. Landlord may exercise the right to so relocate
         Tenant under this paragraph at any time including but not limited to,
         the period before Tenant takes possession of Premises. If Landlord
         moves Tenant to such new space, this Lease and each and all of its
         terms, covenants and conditions shall remain in full force and effect
         and be deemed applicable to such new space, and such new space shall
         thereafter be deemed to be the "Premises". It is agreed that Park shall
         mean any of those present buildings known as, or future buildings that
         may be built adjacent to and be known as, Roswell Summit Office Park,
         Holcomb Bridge Road, Roswell, Georgia.

37.      EXCULPATION OF LANDLORD:

         Landlord's liability with respect to or arising from or in connection
         with this Lease shall be limited solely to Landlord's interest in the
         Building. Neither Landlord, any of the partners of Landlord, any
         officer, director, principal, trustee, policyholder, shareholder nor
         employee of Landlord shall have any personal liability whatsoever with
         respect to this Lease.

         Landlord shall have absolutely no personal liability with respect to
         any provision of this Lease or any obligation or liability arising from
         this Lease or in connection with this Lease. Tenant shall look solely
         to the equity of the Landlord in the Building for the satisfaction of
         any money judgment to Tenant. Such exculpation of liability shall be
         absolute and without exception whatsoever.

38.      HAZARDOUS WASTE:

         Neither Tenant, its successors or assigns, nor any permitted assignee
         or sublessee, licensee or other person or entity acting by or through
         Tenant, shall (either with or without negligence) cause or permit the
         escape, disposal or release of any "Hazardous Substances, or Materials"
         (as hereunder defined). Tenant shall not allow the storage or use of
         such Hazardous Substances or Materials In any manner not sanctioned by
         law and by the highest standards prevailing in the industry for the
         storage and use of such Hazardous Substances or Materials, nor allow to
         be brought into the Building or the Premises any such Hazardous
         Substances or Materials except to use in the ordinary course of
         Tenant's business, relative to office copiers and then only if such
         Hazardous Substances or Materials are not prohibited by (and are only
         in amounts permitted by) law, after notice is given to Landlord of the
         identity of such Hazardous Substances or Materials. Without limitation,
         Hazardous Substances or Materials shall include any biologically or
         chemically active substance and any waste, substance or material

         seq., any applicable state or local laws and the regulations adopted
         under these acts. If any lender or governmental agency shall ever
         require 

   17

         testing to ascertain whether or not there has been any release of
         Hazardous Substances or Materials, then the reasonable costs thereof
         shall be reimbursed by Tenant to Landlord upon demand as additional
         charges if such requirement applies to the Premises. In addition,
         Tenant shall execute affidavits, representations and the like from time
         to time at Landlord's request concerning Tenant's best knowledge and
         belief regarding the presence of Hazardous Substances or Materials on
         the Premises. Tenant indemnifies and covenants and agrees at its sole
         cost and expense, to protect and save Landlord harmless against and
         from any and all damages, losses, liabilities, obligations, penalties,
         claims, litigation, demands, defenses, judgments, suits, proceedings,
         costs, or expenses of any kind or of any nature whatsoever (including
         without limitation, reasonable attorney's fees and expert's fees) which
         may at any time be imposed upon, incurred by or asserted or awarded
         against Landlord arising from or out of any Hazardous Substances or
         Materials on, in, under or affecting the Premises, the Building or the
         Property or any part thereof as a result of any act or omission by
         Tenant, its successors or assigns, or any permitted assignee, permitted

         Lease and shall have no effect upon the construction or interpretation
         of any part hereof. This Lease shall be construed and governed by the
         laws of the State of Georgia.

40.2     Heirs and Assigns: All of the covenants, agreements, terms and
         conditions contained in this Lease shall inure to and be binding upon
         Landlord and Tenant and their respective heirs, executors,
         administrators, successors and assigns.

40.3     No Brokers: Tenant represents and warrants to Landlord that it has not
         engaged any broker, finder, or other person who would be entitled to
         any commission or fees in respect of the negotiation, execution or
         delivery of this Lease other than C.B. Commercial Real Estate Group,
         Inc. and shall indemnify and hold harmless Landlord against any loss,
         cost, liability or expense incurred by Landlord as a result of any
         claim asserted by any other broker, finder or other person on the basis
         of any arrangements or agreements made or alleged to have been made by
         or on behalf of Tenant. The provisions of this Section 40.3 shall not
         apply to brokers with whom Landlord has an express written brokerage
         agreement.

40.4     Entire Agreement: This Lease contains all covenants and agreements
         between Landlord and Tenant relating In any manner to the Rent, use and
         occupancy of the Premises and Tenant's use of the Park and other matter
         set forth in this Lease. No prior agreements or understanding
         pertaining to the same shall be valid or of any force or effect and the
         covenants and agreements of this Lease shall not be altered, modified
         or added to except in writing signed by Landlord and Tenant.

40.5     Severability: If any clause or provision of this Lease Is or becomes
         illegal, invalid, or unenforceable because of present of future laws or
         any rule or regulation of any governmental body or entity, effective
         during its term, the intention of the Lease shall not be affected
         thereby, unless such invalidly is, in the sole determination of
         Landlord, essential to the rights of both parties, in which event
         Landlord has the right to terminate this Lease on written notice to
         Tenant.

40.6     Late Charges: Tenant hereby acknowledges that late payment to Landlord
         of Rent or other sums due hereunder will cause Landlord to incur costs
         not contemplated by this Lease, the exact amount of which will be
         extremely difficult to ascertain. If any Rent or other sum due from
         Tenant is not received by Landlord or Landlord's designated agent
         within ten (10) days after its due date, then Tenant shall pay to
         Landlord a late charge equal to the maximum amount permitted by law (
         and in the absence of any governing law, such overdue amount shall bear
         interest at two (2) points over the prevailing Prim ' e Rate as quoted
         by The Wall Street Journal percent change as of the first day of the
         month in which said Rent becomes past due), plus reasonable attorney's
         fees incurred by Landlord by reason of Tenant's failure to pay Rent
         and/or other charge when due hereunder. The parties hereby agree that
         such late charges represent a fair and reasonable estimate of the cost
         that Landlord will incur by reason of Tenant's late payment. Landlord's
         acceptance of such late charges shall not constitute a waiver of
         default with respect to such overdue amount or estop Landlord from
         exercising any of the other rights and remedies granted hereunder.

40.7     Force Majeure: Time periods for Landlord's or Tenant's performance
         under any provisions of this Lease shall be extended for periods of
         time during which the non-performing party's performance is 

   18

         prevented due to circumstances beyond the party's control, including
         without limitation, strikes, embargoes, governmental regulations, acts
         of God, war or other strife.

40.8     Homestead and Attorney's Fees: Tenant hereby waives and renounces for
         itself any and all homestead or exemption rights which it may have
         under or by virtue of the Constitution and Laws of the United States
         and the State of Georgia, and any other state as against any debt
         Tenant may owe Landlord under this Lease, and Tenant hereby transfers,
         conveys and assigns to Landlord all homestead or exemption rights which
         may be allowed or set apart to Tenant including such as may be set
         apart in bankruptcy proceedings, to pay any debt Tenant may owe
         Landlord hereunder.

         power given it herein or to insist upon strict compliance by Tenant
         with any obligation imposed on it herein, and no custom or practice or
         either party hereto at variance with any term hereof shall constitute a
         waiver or a modification of the terms hereof by Landlord of any right
         it has herein to demand strict compliance with the terms hereof by
         Tenant. No officer, agent, or employee of Landlord has or shall have
         any authority to waive any provisions of this Lease unless such waiver
         is expressly made in writing and signed by an authorized officer of
         Landlord.

40.10    Time of Essence: Time is of the essence of this Lease.

40.11    No Estate in Land: This Lease shall create the relationship of Landlord
         and Tenant between Landlord and Tenant; no estate shall pass out of
         Landlord and Tenant has only a usufruct which is not subject to levy
         and sale.

         of Georgia.

         the Premises or the Building and shall not install, repair or replace
         any aerial, fan, air-conditioner or other device on the roof of the
         Premises of the Building without the prior written consent of Landlord.
         Any aerial, fan, air-conditioner or other device installed without such

         without notice, at any time.

         nonexclusive basis, and without charge, four (4) parking spaces in the

         Premises. Tenant agrees to abide by such reasonable rules and
         regulations for parking use as Landlord may from time to time impose.

40.15    Tenant Improvement Allowance: Landlord shall construct the Premises
         from slab floor to finished and installed ceiling grid, using building
         standard materials in accordance with construction drawings which shall
         be prepared based upon the floor plan set forth in Exhibit A and which
         shall be approved by Tenant, whose approval shall not be unreasonably
         withheld. No construction of improvements will commence until the final
         construction drawings have been approved and initialed by the Tenant.
         Once construction of the improvements has commenced, any subsequent
         modifications to the construction drawing shall be made at Tenant's
         expense.

         in writing to Landlord any defective condition in or about the Premises

         telephone immediately in such instance.

         hereby grants to Tenant an option to renew this Lease for one period of

         Fulton, State of Georgia, described as 1080 Holcomb Bridge Road -
         Roswell Summit, Building 100, Suite 135 ("Master Premises"). 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 following portion of the Master Premises
         ("Premises"): Approximately 3,938 square feet, Building 100, Suite 135.
         The Sublessee agrees to take the premises "As Is"; and that no tenant
         improvement work is to be performed by QRE Holding Company as the
         landlord relative to the Sublease.

4.       WARRANTY BY SUBLESSOR.

         Sublessor warrants and represents to Sublessee that the Master Lease
         has not been amended or modified except as expressly set forth herein,
         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.

         The Term of this Sublease shall commence on February 15, 1997,
         ("Commencement Date"), or when Lessor consents to this Sublease (if
         such consent is required under the Master Lease), whichever shall last
         occur, and end on November 30, 1998 , ("Termination Date"), unless
         otherwise sooner terminated in accordance with the provisions of this
         Sublease. In the event the Term commences on a date other than the
         Commencement Date, Sublessor and Sublessee shall execute a memorandum
         setting forth the actual date of commencement of the Term. Possession
         of the Premises ("Possession") shall be delivered to Sublessee on the
         commencement of the Term. If for any reason Sublessor does not deliver
         Possession to Sublessee on the commencement of the Term, 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. Notwithstanding the foregoing, if Sublessor has not
         delivered Possession to Sublessee within ten (10) days after the
         Commencement Date, then at any time thereafter and before 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
         three (3) days after delivery of said notice to Sublessor. If Sublessor
         delivers Possession to Sublessee on or before such effective date, this
         Sublease shall remain in full force and effect. If Sublessor fails to
         deliver Possession to Sublessee on or before such effective date, 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. 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. In addition the Subtenant has no right
         to extend the lease term.

                  execution of this Sublease Five Thousand Three Hundred Thirty
                  Two and 71/100 Dollars ($5,332,71) as rent for March 1997. If
                  the Term begins or ends on a day other than the first or last
                  day of a month, the rent for the partial

         Dollars ($15,998.12) as security for Sublessee's faithful performance
         of Sublessee's obligations hereunder ("Security Deposit"). If Sublessor
         fails to pay rent or other charges when due under this Sublease, or
         fails to perform any of its other obligations hereunder, Sublessor may
         use or apply all or any portion of the Security Deposit for the payment
         of any rent or other amount then due hereunder and unpaid, for the
         payment of any other sum for which Sublessor may become obligated by
         reason of Sublessee's default or breach, or for any loss or damage
         sustained by Sublessor as a result of Sublessee's default or breach. If
         Sublessor so uses any portion of the Security Deposit, Sublessee shall,
         within ten (10) days after written demand by Sublessor, restore the
         Security Deposit to the full amount originally deposited, and
         Sublessee's failure to do so shall constitute a default under this
         Sublease. Sublessor shall not be required to keep the Security Deposit
         separate from its general accounts, and shall have no obligation or
         liability for payment of interest on the Security Deposit. In the event
         Sublessor assigns its interest in this Sublease, Sublessor shall
         deliver to its assignee so much of the Security Deposit as is then held
         by Sublessor within (10) days after the Term has expired, or Sublessee
         has vacated the Premises, or any final adjustment pursuant to
         Subsection 6.2 hereof has been made, whichever shall last occur, and
         provided Sublessee is not then in default of any of its obligations
         hereunder, the Security Deposit or so much thereof as had not
         theretofore been applied by Sublessor, shall be applied to the last two
         months of the term, if any, of Sublessee's interest hereunder.

8.       USE OF PREMISES.

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

9.       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 term of the Master Lease).

10.      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 following: None*.
         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, except that the obligation to pay rent
         to Lessor under the Master Lease shall be considered performed by
         Sublessee to the extent and in the amount rent is paid to Sublessor in
         accordance with Section 6 of this Sublease. Sublessee shall not 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 nondefaulting party
         for the damage suffered as a result of such termination.
         Notwithstanding the foregoing, if the Master Lease gives Sublessor any
         right to terminate the Master Lease in the event of the partial or
         total damage, destruction, or condemnation of the Master Premises or
         the building or project of which the Master Premises are a part, the
         exercise of such right by Sublessor shall not constitute a default or
         breach hereunder.

be construed as an amendment to the Lease Agreement in any report.
