      4. Additional Rental. Section 2.03 of the Lease is hereby amended to
provide that notwithstanding anything in this Lease to the contrary, Tenant will
be responsible for Tenant's Percentage Share of all taxes, assessments and
governmental charges, costs of all insurance relating to the Building,
utilities, snow removal, landscaping and charges assessed against or attributed
to the Building pursuant to any applicable declaration of protective covenants
("Uncontrollable Operating Expenses"), without regard to the level of increase
in any or all of the above in any year or other period of time. Tenant's
obligation to pay all other Operating Expenses that are not Uncontrollable
Operating Expenses (herein "Controllable Operating Expenses") shall be limited
to a five percent (5%) per annum increase, on a cumulative basis, over the
amount the Controllable Operating Expenses for the immediately preceding
calendar year would have been had the Controllable Operating Expenses increased
at the rate of five percent (5%), on a cumulative basis, in all previous
calendar years, beginning with the actual Controllable Operating Expenses for
the year ending December 31, 2005.

      5. Security Deposit. Section 2.05 of the Lease is hereby amended to
provide as follows:

      (a) As security for the faithful performance by Tenant throughout the
Term, and any extensions or renewals thereof, of all the terms and conditions of
this Lease on the part of Tenant to be performed, Tenant shall deposit with
Landlord a Security Deposit in the amount of $34,543.00. Such amount shall be
returned to Tenant, without interest, within thirty (30) days after the day set
for the expiration of the Term, or any extension or renewal thereof, provided
Tenant has fully and faithfully observed and performed all of the terms,
covenants, agreements, warranties and conditions hereof on its part to be
observed and performed. Landlord shall have the right, at any time, to apply all
or any part of said Security Deposit toward the cure of any default of Tenant,
the repair of any damage to the Leased Premises or otherwise caused by Tenant,
or the amount of any Rent owing under the Lease. No application of the Security
Deposit shall be construed to limit Landlord's right to recover additional sums
from Tenant for damages to the Leased Premises. If all or any part of said
Security Deposit is so applied by Landlord, then Tenant shall immediately pay to
Landlord an amount sufficient to return said Security Deposit to the balance on
deposit with Landlord prior to said application.

<PAGE>

            (b) In no event shall Tenant be entitled to apply the Security
Deposit to any Rent due under the Lease. In the event of an act of bankruptcy by
or insolvency of Tenant, or the appointment of a receiver for Tenant or a
general assignment for the benefit of Tenant's creditors, then the Security
Deposit shall be deemed immediately assigned to Landlord. The right to retain
the Security Deposit shall be in addition and not alternative to Landlord's
other remedies under the Lease or as may be provided by law and shall not be
affected by summary proceedings or other proceedings to recover possession of
the Leased Premises.

            (c) In the event of a sale or transfer of Landlord's interest in the
Leased Premises or the Building or a lease by Landlord of the Building, Landlord
shall have the right to transfer the within described security deposit to the
purchaser or lessee, as the case may be, and Landlord shall be relieved of all
liability to Tenant for the return of such Security Deposit. Tenant shall look
solely to the new owner or lessee for the return of said Security Deposit. The
Security Deposit shall not be mortgaged, assigned or encumbered by Tenant. In
the event of a permitted assignment or subletting under the Lease by Tenant, the
Security Deposit shall be held by Landlord as a deposit made by the permitted
assignee or subtenant and the Landlord shall have no further liability with
respect to the return of said Security Deposit to the original Tenant.

            (d) Landlord shall not be required to keep the Security Deposit
separate from its general accounts.

      6. Renewal Option. Landlord hereby grants to Tenant a Renewal Option as
set forth on Exhibit H attached to this Sixth Amendment.

      7. Right of First Offer. Landlord hereby grants to Tenant a Right of First
Offer as set forth on Exhibit I attached to this Sixth Amendment.

      8. Tenant Improvement Allowance. As of September 1, 2005, Landlord shall
provide Tenant with an Allowance equal to $10.00 per square foot of net rentable
area in the Leased Premises ($218,170.00), and Tenant shall apply such allowance
to the upgrade and improvement of the Leased Premises (including but not limited
to cabling and wiring of the Leased Premises) pursuant to mutually agreeable
plans and specifications. Tenant shall pay Landlord promptly, as additional
rental under the Lease and within thirty (30) days of being invoiced therefore,
the cost of any such improvements, less the amount of such Allowance; provided,
however, if Tenant has not used the entire Allowance by September 1, 2006,
Tenant may elect to use up to $3.00 per square foot of net rentable area in the
Leased Premises ($65,451.00) of the Allowance to offset the Net Rental next
coming due under the Lease. The provisions of Exhibit D to the Lease, as
applicable, shall apply with respect to all improvements in the Leased Premises.
Notwithstanding the foregoing, Tenant may perform all such work to the Leased
Premises with a contractor approved by in advance by Landlord, provided that (i)
any mechanical, electrical and plumbing ("MEP") work must be approved in advance
and drawn by Landlord's MEP architect, and (ii) all MEP-related work must be
performed by subcontractors approved in advance by Landlord. In addition, Tenant
shall pay to Landlord construction management fee equal to five percent (5%) of
the total cost of all work associated with such improvements to the Leased
Premises. Such fee shall be paid to Landlord or Landlord's designated agent, and
may be funded out of the Allowance, to the extent available.

Parking Permits. In addition, Landlord shall permit Tenant the use of an
additional four (4) Assigned Parking Permits on a month to month basis, to the

represented Tenant in this transaction. Landlord will pay each of Landlord's
Broker and Tenant's Broker a commission due by virtue of this Second Amendment,

                                 RENEWAL OPTION

Tenant shall have the right to renew the Term of this Lease for one (1)
additional period of five (5) years (the "Renewal Term"), by giving Landlord
prior written notice no less than nine (9) months prior to the otherwise
effective expiration of the Term, that Tenant intends to exercise either of such
renewal rights, subject to the following conditions:

            (a) Tenant shall be in possession of the Leased Premises and there
shall not be an event of default under any of the terms or provisions of this
Lease at the time such notice is given or at the time of the commencement of the
Renewal Term.

            (b) Tenant shall occupy the Leased Premises during the Renewal Term
under the same terms and conditions as specified in this Lease, except Tenant
shall be entitled to no additional tenant improvement allowance and the Net
Rental for any Renewal Term shall be the then Market Rate.

            (c) As used herein, the term "Market Rate" shall be determined by
Landlord as the amount of base annual rent per square foot then being charged in
comparable first-class office buildings located in the Buckhead area of Atlanta,
Georgia for space comparable to the Leased Premises and taking into
consideration all other relevant factors establishing similarity or
dissimilarity between the comparable lease and the leasing of the Leased
Premises to Tenant for the Renewal Term, including without limitation,
escalations (including type, base year and stop), concessions, length of Term,
size and location of the Leased Premises, building standard work letter and/or
tenant improvement allowances, amenities offered, location of building, the cost
and provision of parking spaces, and other generally applicable concessions,
allowances, terms and conditions of tenancy. In determining the Market Rate, the
greatest weight shall be accorded to leases in the Building for comparable space
entered into in the twelve (12) months preceding the date on which the Market
Rate is determined.

            (d) Within thirty (30) days after Landlord receives the notice of
Tenant's exercise of the renewal option, Landlord shall notify Tenant of the
proposed Market Rate. In the event that Landlord and Tenant are not able to
agree as to the Market Rate within sixty (60) days of good faith negotiation,
Tenant's right of renewal as provided herein shall terminate.

            (e) In the event Tenant fails timely to notify Landlord in the
manner herein specified, Tenant shall be conclusively deemed to have waived its
right to enter into any Renewal Term.

            (f) This renewal right shall be subject to review and approval by
Landlord, in its reasonable discretion, of Tenant's credit and financial
condition at the time of such renewal.

                                    EXHIBIT I

                              RIGHT OF FIRST OFFER

Subject to the rights of existing tenants, Landlord hereby grants to Tenant a
right of first offer to lease any space of less than 5,000 square feet of net
rentable area located on the sixth (6th) floor of the Building, which right
shall be exercised by Tenant or its parent, subsidiary, or affiliate, by written
notice given to Landlord within ten (10) business days after Landlord provides
written notice to Tenant that Landlord is negotiating to lease the ROFO Space to
another occupant (Tenant's failure to provide such notice by the expiration of
such ten (10) business day period being deemed Tenant's waiver of any right to
lease the ROFO Space), subject to the following conditions:

            (a) Tenant, or its parent, subsidiary, or affiliate, shall be in
possession of the Leased Premises and there shall not be an Event of Default by
Tenant under any of the terms or provisions of this Lease at the time Landlord
provides such notice to Tenant.

            (b) Tenant, or its parent, subsidiary, or affiliate, shall occupy
the Leased Premises (including but not limited to the ROFO Space) during the
Renewal Term under the same terms and conditions as specified in this Lease,
except that:

                  (i) Landlord shall provide to Tenant an Allowance with respect
      to the ROFO Space equal to the product of (A) the Allowance per square
      foot of rentable area originally provided to Tenant under the Lease,
      multiplied by (B) a fraction, the numerator of which is the number of
      months remaining in the Term of the Lease at the time Tenant first
      occupies the ROFO Space, and the denominator of which is the number of
      months in the entire Term at the time Tenant first occupies the ROFO
      Space;

                  (ii) To the extent Landlord is then offering additional tenant
      concessions, Landlord shall provide to Tenant such concessions prorated as
      set forth in clause (i) above; and

                  (iii) In the event less than thirty-six (36) months remain in
      the Term at the time Tenant first occupies the ROFO Space, the Term of the
      Lease (as to both the original Leased Premises and the ROFO Space)
      automatically shall be extended to expire on the date that is thirty-six
      (36) months after the date Tenant first occupies the ROFO Space.

            (c) Tenant's right of first offer shall not be applicable during any
Renewal Term.
