         WHEREAS, Landlord, as landlord, and Tenant, as tenant, entered into

First Amendment to Lease Agreement dated February 21, 2000, and as further
amended by that certain Consent to Sublease dated June 13, 2001 (such lease,

approximately 31,622 rentable square feet of space (the "Premises") in the
building known as Two Lakeside Commons (the "Building") and located at 980
Hammond Drive, Atlanta, Fulton County, Georgia; and

         WHEREAS, the Premises consist of 8,163 rentable square feet of space on
the eighth floor of the Building and known as Suite 850 (the "Eighth Floor
Space") and 23,459 rentable square feet of space on the twelfth floor of the
Building and known as Suite 1200 (the "Twelfth Floor Space"); and

         WHEREAS, the Term of the Lease relating to the entire Premises is
scheduled to expire on August 31, 2004; and

         WHEREAS, Tenant desires that the Lease as it pertains to the Twelfth

the Term of the Lease; and

         WHEREAS, Landlord is willing to cancel and terminate that portion of

conditions hereinafter set forth.

         NOW, THEREFORE, for and in consideration of the premises, the payment

Landlord the sum of Five Hundred Thousand and No/100 Dollars ($500,000.00) (the

any and all claims Tenant has or may have had with respect to and surrendered to
Landlord the

<PAGE>

security deposit on account with Landlord in the amount of Forty Six Thousand
Nine Hundred Eighteen Dollars ($46,918.00). Subject to the payment of the
Termination Fee and certain other conditions as set forth herein, Landlord and
Tenant do hereby cancel and terminate the Lease as it pertains to the Twelfth
Floor Space effective as of 11:59 p.m. on December 31, 2001 (the "Effective

         (b) Upon the full and timely payment of the entire Termination Fee by
Tenant and satisfaction of all of the other terms and conditions of this
Agreement by Tenant, the Lease as it pertains to the Twelfth Floor Space shall
be canceled and terminated, and it is agreed that, except as specifically set
forth in Section 4 of this Agreement, neither Landlord nor Tenant shall have any
further rights, liabilities or obligations under the Lease as it pertains to the
Twelfth Floor Space from and after the Effective Termination Date; provided,
however, nothing contained herein shall be construed as releasing Tenant from
any and all obligations, liabilities and duties contained in the Lease as the
same apply to the Eighth Floor Space. Landlord acknowledges that subsequent to
the execution of this Agreement, it may determine that it has incurred a loss,
damage or injury with respect to the Twelfth Floor Space related to the releases
herein given, but which were unknown or unanticipated at the time of execution
of this Agreement, or that it may have had claim(s) or cause(s) of action which
were unknown or unanticipated at the time of the execution of this Agreement,
and Landlord hereby expressly agrees that, except as specifically set forth in
Section 4 of this Agreement, the releases herein given shall apply to all such
unknown, existing and unanticipated losses, damages, injuries, claims and causes
of action related to the Twelfth Floor Space. Effective as of the Effective
Termination Date, Tenant acknowledges and agrees that Tenant's right to
possession of the Twelfth Floor Space has been validly terminated and Tenant has
given, granted and surrendered, and by these presents does give, grant and
surrender unto Landlord, its successors and assigns, the Twelfth Floor Space and
all the rights, usufruct, title and interest of the Tenant in and to the same.
Effective immediately, Landlord shall have the unencumbered right, but not the
obligation, to enter into a third party lease(s) with respect to the same or any
portion thereof.

         2. WARRANTY BILL OF SALE. Simultaneously with the execution of this
Agreement, as additional consideration for Landlord's willingness to enter into
this Agreement, Tenant shall execute and deliver to Landlord a warranty bill of
sale in the form attached hereto as EXHIBIT "A" conveying to Landlord the
furniture, fixtures and equipment presently located in the Twelfth Floor Space
("Tenant's FF&E") as identified in the bill of sale.

         3. RELEASE BY TENANT. Effective immediately, Tenant, on behalf of
itself and on behalf of any other person or entity claiming through or under
Tenant, does hereby release and forever discharge Landlord, its general partners
and limited partners, and Landlord's and its partners' respective directors,
officers, employees, shareholders, members, managers, agents, assigns,
attorneys, successors, heirs, administrators, executors, representatives, and
all others who may have acted or been claimed to have acted in concert with
Landlord, who are liable or who might be claimed to be liable from any and all
claims, charges, complaints, liabilities, obligations, promises, agreements,
controversies, damages, demands, actions, causes of action or

                                       2
<PAGE>

suits of any kind or nature whatsoever, whether they sound in law, equity, tort
or contract which Tenant may have had, now has, or may have against Landlord or
any such other persons or entities arising out of any act or omission of
Landlord under that portion of the Lease as it pertains to the Twelfth Floor
Space or in any way connected with any and all transactions, occurrences, or
other matters relating to that portion of the Lease as it pertains to the
Twelfth Floor Space. Tenant, on behalf of itself and on behalf of any other
person or entity claiming through or under Tenant, does hereby further release
and forever discharge Landlord and Landlord's successors and assigns from the
return of any security deposit, commitment deposit or advance payment of rent
paid to Landlord by Tenant at any time prior to the execution of this Agreement.
Tenant acknowledges that subsequent to the execution of this Agreement, it may
determine that it has incurred a loss, damage or injury related to the releases
herein given, but which were unknown or unanticipated at the time of execution
of this Agreement, or that it may have had claim(s) or cause(s) of action which
were unknown or unanticipated at the time of the execution of this Agreement,
and Tenant hereby expressly agrees that the releases herein given shall apply to
all such unknown, existing and unanticipated losses, damages, injuries, claims
and causes of action or other matters relating to the Lease as it pertains to
the Twelfth Floor Space.

         4. CONTINUED LIABILITY OF TENANT. Notwithstanding anything contained
herein to the contrary, Landlord specifically reserves unto itself the right to
pursue a claim for nonpayment of, and Tenant shall remain liable for payment of
and agrees to pay, any sums owing under the Lease as it pertains to the Twelfth
Floor Space, through and including the Effective Termination Date. Without
limiting the generality of the foregoing, Tenant acknowledges and agrees that
the provisions of the Lease with respect to the payment of Additional Rent, as
it pertains to the Twelfth Floor Space, shall survive the termination of that
portion of the Lease as it pertains to the Twelfth Floor Space such that Tenant
shall remain liable and responsible for any amounts due from Tenant in
accordance with the provisions of the that portion of the Lease as it pertains
to the Twelfth Floor Space for the period through and including Effective
Termination Date, but which amounts may not be reconciled until after the
Effective Termination Date. All of the obligations of Tenant set forth in this
Section shall survive the termination of that portion of the Lease as it
pertains to the Twelfth Floor Space and the surrender of the Twelfth Floor
Space. Notwithstanding anything to the contrary contained in this Agreement,
nothing contained herein shall release Landlord or Tenant from any of their
respective obligations, liabilities and duties under the Lease as they pertains
to the Eighth Floor Space, and Landlord and Tenant acknowledge and agree that
the Lease as it pertains to the Eighth Floor Space remains in full force and
effect, and shall remain in full force in effect after the Effective Termination
Date, until such time as the Lease, as it pertains to the Eighth Floor Space,
expires or is earlier terminated in accordance with the terms of the Lease.
