                            AFCO REALTY SERVICES, LLC

                           STANDARD SUBLEASE AGREEMENT

THIS SUBLEASE AGREEMENT is made on November 20, 2000, by and among Chevron USA
Inc. (hereinafter "Sublessor") and Manhattan Associates, Inc. (hereinafter
"Sublessee"), AFCO Realty Services, LLC (hereinafter "Broker") and Insignia/ESG,
Inc. (hereinafter "Co-Broker").

1.       MASTER LEASE. Sublessor is the tenant under that certain lease dated
         June 15 1989, wherein Wildwood Associates (hereinafter "Landlord")
         leased to Sublessor the real property located in the City of Atlanta,
         County of Cobb, State of GA, described as 2300 Windy Ridge Parkway,
         Suite 800 (hereinafter "Master Premises"). Said lease has been amended
         by the following amendments: 1st May 11, 1990, 2nd December 20, 1990,
         3rd August 15, 1991, 4th September 10, 1992, 5th September 30, 1992,
         6th July 29, 1994, 7th August 31, 1998; said lease and amendments are
         herein collectively referred to as the "Master Lease" and are attached
         hereto as Exhibit "A." 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 Landlord that Sublessor is in default or
         breach of any of the provisions of the Master Lease.

2.       PREMISES. Sublessor hereby subleases to Sublessee on the terms and
         conditions set forth in this Sublease the following portion of the
         Master Premises (hereinafter "Premises"): 5,448 rentable square feet as
         attached hereto as Exhibit "B".

3.       TERM. The Term of this Sublease shall commence on November 20, 2000,
         (hereinafter "Commencement Date") or the date upon which Landlord
         consents to this Sublease (if such consent is required under the Master
         Lease), whichever shall last occur, and shall end on March 3, 2005
         (hereinafter "Termination Date") unless otherwise sooner terminated in
         accordance with the provisions of this Sublease.

4.       COMMENCEMENT. In the event the Term commences on a date other than the
         Commencement Date, Sublessor and Sublessee shall promptly execute a
         memorandum setting forth the actual date of commencement of the Term.
         Possession of the Premises (hereinafter "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 thirty (30) 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 ten (10) 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
         pursuant to 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.

5.       RENT. (A) MINIMUM RENT. Sublessee shall pay to Sublessor as minimum
         rent (which includes 2001 base year expenses), without deduction,
         setoff, notice, or demand at P. 0. Box 297864, Houston, TX 77297 or at
         such other place as Sublessor shall designate from time to time by
         notice to Sublessee, the sum of Eight Thousand Six Hundred Twenty Six
         and no/100 Dollars ($8,626.00) per month, in advance on the first day
         of each month of the Term. Sublessee shall pay to Sublessor upon
         execution of this Sublease the sum of Eight Thousand Six Hundred Twenty
         Six and no/100 Dollars ($8,626.00) as rent for November 2000. If the
         Term begins or ends on a day other than the first or last day of a
         month, the rent for the partial months shall be prorated on a per diem.

         (B) OPERATING COSTS. If the Master Lease requires Sublessor to pay to
         Landlord all or a portion of the expenses of operating the building
         and/or project of which the Premises are a part, including, but not
         limited to, taxes, utilities, or insurance (hereinafter "Operating
         Costs") then Sublessee shall pay to Sublessor as additional rent ten
         and six tenths percent (10.6%) of the amounts payable by Sublessor for
         Operating Costs incurred during the Term. Such additional rent shall be
         payable as and when Operating Costs are payable by Sublessor to
         Landlord. If the Master Lease provides for the payment by Sublessor of
         Operating Costs on the basis of an estimate thereof, then as and when
         adjustments between estimated and actual Operating Costs are made under
         the Master Lease, the obligations of Sublessor and Sublessee hereunder
         shall be adjusted in a like manner; and if any such adjustment shall
         occur after the expiration or earlier termination of the Term, then the
         obligations of Sublessor and Subleases under this Paragraph 5(b) shall
         survive such expiration or termination. Sublessor shall, upon request
         by Sublessee, furnish Sublessee with copies of all statements submitted
         by Landlord of actual or estimated Operating Costs during the Term.
         (See Special Stipulations, paragraph 1, attached hereto.)

6.       LATE CHARGES. Other remedies for nonpayment of rental notwithstanding,
         time is of the essence of this Sublease and if Sublessor elects to
         accept rent on or after the sixth (6th) day of the month, a late charge
         equal to the greater of five percent (5%) of the monthly rent or One
         Hundred Dollars ($100.00) will be due as additional rent. Sublessee
         agrees to tender all late rents by cashier's check, certified check, or
         money order. In the event Sublessee's rent check is dishonored by the
         bank. Sublessee agrees to pay Sublessor $25.00 as a handling charge
         and, if applicable, the late charge, and Sublessee shall deliver said
         monies to Sublessor as specified in Paragraph 5. Dishonored checks must
         be replaced by cashier's check, certified check or money order. In the
         event more than one check is dishonored, Sublessee agrees to pay all
         future rents and charges in the form of cashier's check, certified
         check, or money order. Any other amounts payable to Sublessor under
         this Sublease, with the exception of rent, shall be considered past due
         30 days from Sublessor's billing date and Sublessee shall pay a monthly
         service charge of 5% of the amount past due for that and each
         subsequent month that the amount remains past due. The parties agree
         that such charges represent a fair and reasonable estimate of the costs
         the Sublessor will incur by reason of such late payment and/or returned
         check.

7.       [DELETED IN ITS ENTIRETY.]

8.       ACCEPTANCE OF PREMISES. Sublessor, Broker and Co-Broker have made no
         representations or promises with respect to the Premises, or this
         Sublease except as herein expressly set forth. The taking of Possession
         of the Premises by Sublessee shall be conclusive evidence that
         Sublessee accepts the Premises "as is" and that the Premises and are
         suitable for the use intended by Sublessee and were in good and
         satisfactory condition at the time such Possession was so taken.

9.       USE OF PREMISES. Sublessee shall use the Premises for general office
         use and for all lawful activities normally incidental thereto and
         related to the conduct of Sublessee's business and for no other
         purpose.

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 Landlord thereunder, Sublessee the Tenant
         thereunder, and the Premises the Master Premises, except for the
         following: no exceptions. Sublessee assumes and agrees to perform the
         Tenant's obligations under the Master Lease during the Term to the

                                       2

         extent that such obligations are applicable to the Premises, except the
         obligation to pay rent to Landlord. 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 Landlord 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.

11.      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 shall not be unreasonably withheld
         (and without the prior written consent of Landlord, if such is required
         under the terms of the Master Lease).

12.      INDEMNITY & INSURANCE. Sublessee and Sublessor agree to and hereby does
         indemnify and save Sublessee, Sublessor and Landlord harmless against
         all claims for damages to persons or property by reason of Sublessee's
         use or occupancy of the Premises, and all expenses incurred by
         Sublessor or Landlord because thereof, including attorney's fees and
         court costs. Supplementing the foregoing and in addition thereto,
         Sublessee shall during the Term of this Sublease, and at Sublessee's
         expense, maintain in full force and effect comprehensive general
         liability insurance with minimum limits of $500,000.00 per person and
         $1,000,000.00, per incident, and property damage limits of $100,000.00,
         or the minimum amount of coverages required in the Master Lease,
         whichever is greater, which insurance shall contain a special
         endorsement recognizing and insuring any liability accruing to
         Sublessee under the first sentence of this Paragraph 12, and naming
         Sublessor and Landlord as additional insureds. Sublessee shall provide
         evidence of such insurance to Sublessor prior to the commencement of
         the Term of this Sublease. Sublessor and Sublessee each hereby release
         and relieve the other, and waive its right of recovery, for loss or
         damage arising out of or incident to the perils insured against which
         perils occur in, on or about the Premises, whether due to the
         negligence of Sublessor or Sublessee or their Brokers, employees,
         contractors and/or invitees to the extent that such loss or damage is
         within the policy limits of said comprehensive general liability
         insurance. Sublessor and Sublessee shall, upon obtaining the policies
         of insurance required, give notice to the insurance carrier or carriers
         that the foregoing mutual waiver of subrogation is contained in this
         Sublease.

13.      NOTICES. (a) Any notice by either party to the other required or
         permitted under this Sublease shall be valid only if in writing and
         shall be deemed to be duly given only if delivered personally or sent
         by registered or certified mail addressed (1) if to Sublessee, at the
         Premises, and (2) if to Sublessor, at the address set forth herein, or
         at such other address for either party as that party may designate by
         notice to the other, with copy to the Broker(s) at the address set
         forth herein; notice shall be deemed given, if delivered personally,
         upon delivery thereof, and if mailed upon the mailing thereof.

         (b) Sublessee hereby appoints as its agent to receive service of all
         dispossessory or distraint proceedings, the person in charge of the
         Premises at the time of occupying the Premises; and if there is no
         person in charge or occupying same, then such services may be made by
         attachment thereof on the main entrance of the Premises.

14.      ENTIRE AGREEMENT. This Sublease contains the entire agreement of the
         parties hereto, and no representations, inducements, promises or
         agreements, oral or otherwise, between the parties, not embodied
         herein, shall be of any force or effect. No subsequent alteration,
         amendment, change or addition to this Sublease, except as to changes or
