                    NON-NEGOTIABLE PROMISSORY NOTE - AMENDED

$191,858.73                                                      January 1, 2001

         FOR VALUE RECEIVED, the undersigned, Inhibitex, Inc., a Delaware
corporation, with its principal offices at 8995 Westside Parkway, Alpharetta,
Georgia 30004 (the "Maker"), promises to pay to the order of AtheroGenics, Inc.,
a Georgia corporation (the "Holder"), the principal sum of One Hundred
Ninety-One Thousand Eight Hundred Fifty Eight and 73/100 ($191,858.73), together
with interest on so much thereof as is from time to time outstanding and unpaid,
from the date hereof until the principal sum is paid in full, at the rate of
seven percent (7%) per annum, with principal and accrued interest being due and
payable as follows.

1.       PAYMENTS. All payments due hereunder shall be made in lawful money of
         the United States of America at 8995 Westside Parkway, Alpharetta,
         Georgia 30004, or at such other place as Holder may designate in
         writing to the undersigned. Commencing on the date of this Note,
         interest shall accrue and be computed on the daily outstanding balance
         on a 360-day year simple interest basis. Principal and interest shall
         be due and payable monthly, in advance, in accordance with the
         amortization schedule, attached hereto as Attachment A and incorporated
         herein by this reference, commencing on January 1, 2001 and continuing
         on the first day of each month thereafter and including December 1,
         2005, at which time all outstanding principal and accrued but unpaid
         interest will be due and payable in full.

2.       EVENT OF DEFAULT. An event of default shall be deemed to occur if Maker
         fails to make or cause to be made any payments required to be made
         under this Note when the same shall be due and payable and such default
         is not cured within three (3) days after Maker receives written notice
         thereof from Holder.

3.       REMEDIES. Upon the occurrence of an event of default, at the option of
         the Holder, the entire principal amount due hereunder, together with
         all accrued interest and any other amounts due hereunder, shall
         immediately become due and payable.

4.       PREPAYMENT. This Note may be prepaid in full or in part prior to
         maturity, without penalty or fee.

5.       WAIVER. Maker hereby waives diligence, presentment, protest and demand,
         notice of protest, dishonor, notice of dishonor and nonpayment of this
         Note, and expressly agrees that, without in any way affecting the
         liability of Maker, Holder may extend any date or the time for payment
         of sums due hereunder.

6.       CHOICE OF LAW. This Note shall be governed by, and construed and
         enforced in accordance with the laws of the State of Georgia (without
         regard to its rules of conflicts of laws).

7.       COSTS OF COLLECTION. The Maker shall reimburse the Holder for all
         reasonable costs and expenses (including reasonable attorney's fees)
         actually incurred by the Holder in enforcing or collecting, or
         attempting to enforce or collect, the obligations evidenced by this
         Note, whether or not suit is instituted.

8.       SEVERABILITY. Wherever possible, each provision of this Note shall be
         interpreted in such manner as to be effective and valid, but if any
         provision hereof shall be prohibited by law or be otherwise invalid,
         such provision shall be ineffective to the extend of such prohibition
         or invalidity, without invalidating the remainder of such provision or
         the remaining provisions of this Note.

9.       ASSIGNMENT. This Note may not be transferred or assigned by Holder to
         any third party without the prior written permission of Maker.

10.      HEADINGS. The headings and titles used in this Note are intended solely
         for identification and not for any substantive purpose, and no heading
         or title shall in any way limit or extend the provisions hereof.

11.      LIMITATION OF INTEREST. Notwithstanding any provision herein to the
         contrary, the interest rate provided by this Note shall in no case
         exceed the rate allowable under any statute or law applicable to this
         transaction when appropriate consideration is given to borrowers or
         lenders of like character or classification. In the event the rate is
         determined to exceed the rate allowable under any statute or law
         applicable to this transaction, the interest rate shall be the maximum
         allowed by any such statute or law, and any amounts actually paid in
         excess thereof, shall be credited to principal.

         This Amended Non-Negotiable Promissory Note supersedes the note between
Inhibitex, Inc. and AtheroGenics, Inc. executed April 1, 1999. Upon execution of
this Note, there will be no further amounts due on the April 1, 1999 Note.

with offices at 600 Mountain Avenue, Murray Hill, New Jersey 07974
("SUBLANDLORD") and INHIBITEX, INC., a Delaware corporation, with offices at

                             INTRODUCTORY STATEMENTS

         A.       By Lease dated August 30, 2000, as amended or modified from
time to time is hereinafter referred to as the "PRIME LEASE", Sanctuary Park
Realty Holding Company (the "PRIME LANDLORD") leased to Sublandlord certain
space designated as Suite 400, consisting of approximately 13,448 rentable
square feet (the "PREMISES") in the building located at 1165 Sanctuary

         B.       Subtenant has agreed to sublet from Sublandlord the Premises.

         C.       The parties desire to enter into this Sublease defining their
respective rights, duties and liabilities relating to the Subleased Premises
(defined below).

                                   WITNESSETH

         NOW THEREFORE, Sublandlord and Subtenant, in consideration of the
mutual promises and covenants contained herein and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, and
each with intent to be legally bound, for themselves and their respective
successors and assigns, agree as follows:

         1. SUBLEASE

         Sublandlord, for and in consideration of Subtenant's payment of rent
and performance of the covenants contained in this Sublease, hereby demises and
leases to Subtenant approximately the entire thirteen thousand four hundred
forty-eight (13,448) rentable square feet of space of Premises as more
particularly shown on the floor plan which is attached as EXHIBIT A hereto and
as Exhibit B to the Prime Lease (the "SUBLEASED PREMISES").

         2. PRIME LEASE

         (a)      A true copy of the Prime Lease is attached hereto as EXHIBIT
B. Where not expressly inconsistent with the terms hereof and except as
otherwise stated herein to the contrary, this Sublease shall be subject and
subordinate to all of the terms and conditions contained in the Prime Lease as
said terms and conditions affect the Subleased Premises, and all of the terms
and conditions of the Prime Lease, except as otherwise set forth herein, are
hereby incorporated into this Sublease and shall be binding upon Subtenant with
respect to the Subleased Premises to the same extent as if Subtenant were named
as tenant and Sublandlord as landlord under the Prime LEASE. Subtenant shall
comply with each covenant and obligation in the Prime Lease which is
incorporated herein that is applicable to Sublandlord as Tenant under the Prime
Lease, and the terms and conditions of this Sublease. For purposes of this
Sublease, references in the Prime Lease to the "term", or "Term" shall mean the
Term of this Sublease, references in the Prime Lease to the "Lease Expiration
Date" or "expiration date" shall mean the Expiration Date of this Sublease, and
references to the "Premises" in the Prime Lease shall mean the Subleased
Premises, except to the extent such terms are altered, modified or otherwise
agreed to herein. Without limiting the generality of the foregoing, all terms
not expressly defined in this Sublease shall have the meanings given to them in
the Prime Lease. Each party agrees that it shall not do or omit to do anything
which would result in a default under the Prime Lease, and each party agrees to
indemnify and hold the other harmless from and against all claims, demands or
liabilities resulting from such party's breach, violation or nonperformance of
any of its

                                       ii

<PAGE>

obligations under the Prime Lease, as incorporated herein. With the exceptions
set forth herein, Subtenant shall be entitled to all of the rights and
privileges of the Sublandlord as tenant under the terms of the Prime Lease with
respect to the Subleased Premises. The following provisions of the Prime Lease
shall not be incorporated into this Sublease: Sections 1(f), 1(g), 1(h), 1(m),
1(n), 2(b), 2(c), 2(d), 3(a)(ii), 3(b)-(i), 6(e), 8, 10, 14(b), 15, 23, 24, 25,
27, 31, 32, 34, 35, 36, 40, 41, 42, 44, 46(l), 46(o), and, insofar as it relates
to Sublandlord, 46(n), and Exhibits C, D, G, H and I.

         (b)      Sublandlord shall, without in any way limiting any other
rights and remedies set forth herein, have the same rights and remedies with
respect to a breach of this Sublease by Subtenant as the Prime Landlord has with
respect to a breach of the Prime Lease, as if the same were more fully set forth
at length herein, and Sublandlord shall have, with respect to Subtenant, this
Sublease and the Subleased Premises, all of the rights, powers, privileges and
immunities as are had by the Prime Landlord under the Prime Lease.

         (c)      Notwithstanding any contrary provision of the Prime Lease
incorporated herein by reference, Subtenant shall have no right to (i) terminate
this Sublease as to all or any part of the Subleased Premises by reason of a
casualty or condemnation, unless Sublandlord is entitled to a corresponding
termination with respect to a corresponding obligation under the Prime Lease; or
(ii) an abatement of Base Rent or additional rent by reason of casualty or
condemnation, unless Sublandlord receives a corresponding abatement with respect
to its corresponding obligation under the Prime Lease; or (iii) any renewal,
extension or termination of the Term; or (iv) any expansion, relocation,
reduction or modification of the Subleased Premises; or (v) any option, right of
first refusal, or right of first offer with respect to the purchase or lease of
any interest in the real estate which the Subleased Premises are a part or any
other real estate; or (vi) receipt of any payment of, or any other right to
receive or participate in, any increase in the equity value of the real estate
of which the Subleased Premises are a part or any other real estate; or (vii)
entry onto, or use for any purpose of, the roof of the Building in which the
Subleased Premises is located except to the extent set forth in section 6(c)
hereof; or (viii) modify the use permitted hereunder; or (ix) demand an estoppel
certificate from Sublandlord; or (x) demand reimbursement or payment from
Sublandlord in excess of payments actually paid by Prime Landlord and received
by Sublandlord with respect to an exercise of the Prime Landlord's relocation
rights under the Prime Lease; or (xi) the right to self-insure any insurance
obligations; or (xii) any rights of signage except to the extent forth in
section 6(b) hereof, or to determine the name of the Building or similar rights,
as may be reserved to Sublandlord under the terms of the Prime Lease; or (xiii)
any rights of setoff or offset, as may be reserved to Sublandlord under the
terms of the Prime Lease.

         (d)      Except as otherwise provided herein, the time limits contained
in the Prime Lease for the giving of notices, making payments or demands or
performing of any act, condition or covenant on Sublandlord's part, as tenant
thereunder, are changed for the purposes of incorporation herein by reference by
shortening same in each instance by five (5) days, so that Subtenant shall have
a lesser time to observe or perform hereunder than Sublandlord has under the
corresponding provisions of the Prime Lease. In no event, however, shall
Subtenant have less than three (3) business days to so observe or perform an
obligation of Sublandlord under the Prime Lease that Subtenant is obligated to
observe or perform pursuant to the provisions of this Sublease.

         (e)      If the Prime Lease shall be terminated by reason of a default
on the part of Subtenant with respect to any of the terms or conditions of this
Sublease, Sublandlord shall be entitled to recover from Subtenant as liquidated
damages (i) such amount or amounts as will be equal to the damages which Prime
landlord shall be entitled to recover from Sublandlord in connection with such
termination of the Prime Lease, and (ii) the expenses incurred by Sublandlord in
collecting amounts referred to in (ii) above, including but not limited to,
attorneys' fees and disbursements, and any other costs of litigation.

         3. PRIME LANDLORD

         Subtenant agrees to look solely to the Prime Landlord, and not to
Sublandlord, for the performance of all services and obligations of the Prime
Landlord under the Prime Lease with respect to the Subleased Premises.

                                       3

<PAGE>

         4. TERM

         a.       The term ("TERM") of this Sublease shall commence on January
1, 2003 (the "COMMENCEMENT DATE") and shall end, unless sooner terminated as
herein provided or pursuant to law, on November 30, 2003 (the "EXPIRATION
DATE"); provided, however, the effectiveness of this Sublease is subject to
Prime Landlord's consent as required by the Prime Lease.

         b.       Subtenant may, at any time after execution of this Sublease
and consent hereto by Prime Landlord and prior to the Commencement Date, without
incurring any liability for payment of Rent, measure the Subleased Premises, and
design, layout and install its personal property, furniture, furnishings, signs,
telecommunication equipment, office equipment and trade fixtures, in the
Subleased Premises at Subtenant's risk and expense. In exercising the foregoing
rights, Subtenant shall not cause any material interference with or delay to
Sublandlord or to any existing tenant of the Building. Subtenant's indemnity
pursuant to Paragraph 24 of this Sublease and indemnity and repair obligations
pursuant of the Prime Lease that are incorporated into this Sublease shall apply
to Subtenant's early entry under this Paragraph 4(b).

         5. RENT

         a.       Subtenant shall pay to Sublandlord basic rent ("Base Rent") in
the amount of One Hundred Eighty-Eight Thousand Two Hundred Seventy-Two and
00/100 Dollars ($188,272.00) per annum, payable in advance on the first day of
each calendar month commencing on January 1, 2003 through November 30, 2003 in
installments of Fifteen Thousand Six Hundred Eighty-Nine and 33/100 Dollars
($15,689.33) each. In the event the Base Rent commences on a day other than the
1st day of the month or the Term ends on a day other than the last day of the
month, the monthly Base Rent shall be prorated for any partial month.

         b.       In addition to the Base Rent set forth in Subsection 5.a.
above, Subtenant shall pay Sublandlord, as additional rent, all other sums of
money which shall be due and payable by Subtenant under the terms and conditions
of this Sublease.

         c.       The terms "Base Rent" and "additional rent" are sometimes
referred to herein as "Rent" or "rent" and shall include all sums due from
Subtenant to Sublandlord under the terms of this Sublease. All Rent payable to
the Sublandlord hereunder shall be payable at the office of the Sublandlord at
the following address:

                            Lucent Technologies Inc.
                               c/o Bank of America
                                 P.O. Box 277374
                             Atlanta, GA 30384-7374

or at such other address as directed by notice from Sublandlord to Subtenant.
Sublandlord's acceptance of Rent after it shall become due and payable shall not
excuse a delay upon subsequent occasions or constitute a waiver of Sublandlord's
rights. The Rent shall be payable in advance without demand, deduction, set-off
or abatement of any kind. Subtenant's obligation to pay Rent shall survive the
expiration or earlier termination of this Sublease.

         e.       If Subtenant shall fail to pay any installment of Rent before
the sixth day after such Rent is due and payable, Subtenant shall pay a charge
(the "Late Charge") which shall be 5% of the amount of such unpaid installment
of Rent. The parties agree that the amount of such Late Charge represents a
reasonable estimate of the cost and expense that will be incurred by Sublandlord
in processing each delinquent payment of Rent by Subtenant and that such Late
Charge shall be paid to Sublandlord as liquidated damages for each delinquent
payment.

         6. PARKING, SIGNAGE, AND SATELLITE DISH

         (a)      Subject to the terms of the Prime Lease, Subtenant, during the
Term hereof, shall have all parking rights and privileges of Sublandlord under
the terms of the Prime Lease.

         (b)      Subtenant shall be entitled to all signage rights of the
Sublandlord under the terms of the Prime Lease, provided all signage shall be at
Subtenant's sole costs and expense and shall be subject to Prime Landlord's
consent or approval if required under the terms of the Prime Lease.

         (c)      Subtenant, at Subtenant's sole cost and expense, and subject
to the terms and conditions of the Prime Lease and the prior written consent of
the Prime Landlord if required

                                       4

under the terms of the Prime Lease, shall be entitled to use a portion of the

         7. FURNITURE.

         As of the Commencement Date, Sublandlord hereby quitclaims to Subtenant
all right title and interest in and to the existing furniture in the Subleased
Premises (the "Furniture"), free and clear of any liens or encumbrances of
Sublandlord, but without any warranty or representation of any kind whatsoever,
and Subtenant agrees to accept title to the Furniture without recourse to
Sublandlord. As of the Commencement Date, Subtenant accepts the condition of the
Subleased Premises and the Furniture in their respective current "As-Is"
conditions and agrees to pay as and if due, and indemnify and hold harmless
Sublandlord from and against any and all personal property, sales or use taxes
due in connection with the transfer of the Furniture to Subtenant.

         8. SECURITY DEPOSIT

         (a)      Subtenant shall deposit with Sublandlord upon the Subtenant's
execution of this Sublease the amount of Thirty-One Thousand Three Hundred
Seventy-Eight and 66/100 Dollars ($31,378.66) (the "SECURITY DEPOSIT") in cash
as security for the full and faithful performance and observance by Subtenant of
the terms, covenants and conditions of this Sublease, including the surrender of
the Subleased Premises as herein provided.

         (b)      If Subtenant defaults in respect of any of the terms,
covenants or conditions of this Sublease, including the payment of Rent,
Sublandlord may apply or retain the whole or any part of the Security Deposit,
to the extent required for the payment of any Rent or any other sum as to which
Subtenant is in default. If Sublandlord applies or retains any part of the
Security Deposit, Subtenant, upon demand, shall deposit with Sublandlord the
amount so applied or retained so that Sublandlord shall have the full Security
Deposit on hand at all times during the Term and Subtenant's failure to do so
shall be a material breach of this Sublease. If Subtenant shall fully and
faithfully comply with all of the terms, covenants and conditions of this
Sublease, the Security Deposit or any balance thereof shall be returned to
Subtenant within thirty (30) days after the Expiration Date. Subtenant expressly
agrees that Subtenant shall have no right to apply any portion of the Security
Deposit against any of Subtenant's obligations to pay Rent hereunder.

         (c)      Upon a transfer of the Sublandlord's interest in the Sublease,
Sublandlord shall have the right to transfer the cash security to the transferee
and Sublandlord shall thereupon be released by Subtenant from all liability for
the return of such security. Subtenant shall look solely to the new sublandlord
for the return of the Security Deposit and the provisions hereof shall apply to
every transfer or assignment made of the Security Deposit to a new sublandlord.
Subtenant further covenants and agrees that it shall not assign or encumber or
attempt to assign or encumber the Security Deposit as security and that neither
Sublandlord nor its successors nor assigns shall be bound by any such
assignment, encumbrance, attempted assignment or attempted encumbrance.

         9. ALTERATIONS

         Subtenant shall not make any alterations or improvements to the
interior or exterior of the Subleased Premises without the prior written consent

Landlord shall be at Subtenant's sole expense. Upon the expiration or earlier

Subtenant shall be responsible for the cost to repair any damages as a result of
such removal. Notwithstanding anything to the contrary contained in the
foregoing, Subtenant shall not be required to remove any alterations installed
by Sublandlord prior to the commencement of this Sublease.

         10. REPAIRS AND MAINTENANCE

         Any repair and maintenance obligations with respect to the Subleased
Premises which are the responsibility of the Sublandlord, as tenant under the
Prime Lease, shall be performed by Subtenant at Subtenant's sole cost and
expense and in accordance with the requirements of the Prime Lease. In the event
that a condition exists in the Subleased Premises that Prime Landlord is
obligated to repair or maintain under the terms of the Prime Lease, Subtenant
shall look solely to the Prime Landlord for performance such repairs and
maintenance. Sublandlord shall have no

                                       5

         a.       Subtenant shall be entitled to all those services and
utilities which Prime Landlord is required to provide under the terms of the

Landlord for the provision of such services and utilities, and Sublandlord shall
not be responsible for Prime Landlord's failure to provide the same. Sublandlord
shall not be responsible for any interruption of services or utilities and
Subtenant shall not have any right to abate or set-off Base Rent due to
Sublandlord hereunder, unless such abatement or set-off is expressly available

hereunder, within ten (10) days after receipt of Sublandlord's bill therefor,

Five Hundred and 00/100 Dollars ($2,500,000) for bodily injury (including death)
to any number of persons or damage to property arising out of any one
occurrence.

         14. COMPLIANCE WITH LAWS

         (a)      In accordance with the terms of the Prime Lease, Subtenant
shall promptly comply with all laws, statutes, ordinances, rules, orders,

of any and all their departments, bureaus and agencies applicable to the

portion of the Subleased Premises or of all or any of Subtenant's interests in
this Sublease.

         (b)      If Subtenant shall fail to comply with the Legal Requirements,
or if Subtenant shall fail or neglect to make any repairs required by the terms
of this Sublease, and if such breach continues for a period of five (5) days
after notice from Prime Landlord or Sublandlord regarding same, or, if the
breach cannot be cured within five (5) days, if Subtenant has not begun to cure
the breach within such period and does not thereafter diligently prosecute the
cure to completion, then Sublandlord may (but shall not be obligated to) enter
the Subleased Premises and take such actions as are necessary to cure the breach
and comply with any and all of the Legal Requirements, at the cost and expense
of Subtenant; and, in case of Subtenant's failure to pay therefor, such cost and
expense shall be added to the next month's Rent and be due and payable as such.

         15. LIMITATIONS ON SUBLANDLORD'S LIABILITY

         a.       Subtenant acknowledges that Sublandlord has made no
representations or warranties with respect to the Building or the Subleased
Premises except as provided in this Sublease and Subtenant accepts the Subleased
Premises in AS IS condition.

         b.       Sublandlord may assign its interest in the Prime Lease and
this Sublease (and delegate its duties thereunder and hereunder) to any person
or entity and upon any such assignment Subtenant shall then recognize
Sublandlord's assignee as Sublandlord of this Sublease and such assignee shall
be primarily liable for all of the duties, requirements, liabilities and
obligations of the Sublandlord that arise and/or accrue from or after the date
of such assignment, but the original Sublandlord shall remain secondary liable
should such assignee default.

         c.       Sublandlord shall not be required to perform any of the
services and obligations of the Prime Landlord under the Prime Lease, and
insofar as any of the services and obligations of the Sublandlord hereunder are
required to be performed under the Prime Lease by the Prime Landlord thereunder,
Subtenant shall rely on and look solely to the Prime Landlord for the
performance thereof. If the Prime Landlord shall default in the performance of
any of its services and obligations under the Prime Lease pertaining to the
Subleased Premises, Subtenant shall have the right, at Subtenant's expense and
upon prior notice to Sublandlord, and in the name of Sublandlord to make any
demand or institute any action or proceeding, in accordance with and not
contrary to any provision of the Prime Lease, against the Prime Landlord under
the Prime Lease for the enforcement of the Prime Landlord's obligations
thereunder. Subtenant shall defend, indemnify and hold Sublandlord harmless from
and against any suit, action, cost, expense, damage or liability which arises
out of or results from or is alleged to arise out of or result from Subtenant's
exercise of its rights under this paragraph, and Subtenant shall provide to
Sublandlord such security for said indemnity as Sublandlord may in its
reasonable discretion deem appropriate. The foregoing indemnification will
survive the expiration or earlier termination of this sublease. No such failure
or refusal shall constitute an eviction, actual or constructive, and Subtenant
shall not be entitled to cancel this Sublease or to any abatement of the Rent
reserved herein. Notwithstanding anything to the contrary contained in the
foregoing or elsewhere in this Sublease, Sublandlord shall have no liability to
Subtenant for Prime Landlord's failure to (i) comply with any of the terms or
provisions of the Prime Lease or (ii) perform any of Prime Landlord's
obligations thereunder.

         d.       Notwithstanding anything to the contrary contained in this
Sublease, any covenants, representations, indemnifications or other undertakings
of Prime Landlord under the Prime Lease shall not be deemed to be made by, or
otherwise constitute obligations of Sublandlord under this Sublease.

         16. SUBORDINATION

         This Sublease shall be subject and subordinate to the Prime Lease and
any ground lease, and to any mortgage, deed of trust or security interest in
either the Prime Lease or on the fee simple interest in the Building or the land
on which the Building is located.

         17. CASUALTY AND CONDEMNATION

         If the Prime Lease is terminated with respect to the Subleased Premises
pursuant to the Prime Lease for any reason, this Sublease shall automatically
terminate at the same time and Subtenant shall have no claim against Sublandlord
or Prime Landlord for the loss of its subleasehold interest or any of
Subtenant's property. If the Prime Lease is not terminated with respect to the
Subleased Premises upon the occurrence of a casualty or condemnation, the
provisions of the Prime Lease with respect to casualty or condemnation shall
apply to this Sublease and the Subleased Premises.

         18. CONSENT OR APPROVAL OF PRIME LANDLORD

         If the consent or approval of Prime Landlord is required under the
Prime Lease with respect to any matter relating to the Subleased Premises,
Subtenant shall be required first to obtain the consent or approval of
Sublandlord with respect thereto and, if Sublandlord grants such consent or
approval, Sublandlord or Subtenant may forward a request for consent or approval
to the Prime Landlord, but Sublandlord shall not be responsible for obtaining
such consent or approval. Sublandlord shall have no liability to Subtenant for
the failure of Prime Landlord to give its consent.

Landlord has given to Sublandlord its consent hereto in writing; and (b) the
Prime Landlord and the Sublandlord have duly recognized the exercise of the
Early Termination Option per the Prime Lease. Sublandlord shall not be

rights in law or in equity with respect to this Sublease.

         22. HOLDING OVER

         Subtenant shall not be entitled to remain in possession of the
Subleased Premises after expiration or earlier termination of this Sublease;
provided, however, Subtenant may remain in possession of the Subleased Premises
after the expiration or earlier termination of this Sublease in the event
Subtenant and Prime Landlord have agreed to a new lease between Prime Landlord,
as landlord, and Subtenant, as tenant, to commence immediately following such
expiration or termination.

         In the event Subtenant does not immediately surrender the Subleased
Premises with all repairs and maintenance required to be performed by Subtenant
completed, upon the expiration or earlier termination of this Sublease, or after
reentry by Sublandlord without terminating this Sublease, Subtenant shall be a
tenant at sufferance and Rent shall be increased to 200% of the Base Rent,
additional rent and other sums that would have been payable pursuant to the
provisions of this Sublease if the Term had continued during such holdover
period, and Subtenant shall be responsible for all damages incurred by
Sublandlord as a result of the holdover, including without limitation payments
and penalties to the Prime Landlord pursuant to

                                       8

<PAGE>

the Prime Lease and all consequential damages. Such rent shall be computed on a
monthly basis and shall be payable on the first day of such holdover period and
the first day of each calendar month thereafter during such holdover period
until the Subleased Premises shall have been vacated and surrendered in
accordance with the terms and provisions of this Sublease. Sublandlord's
acceptance of such rent shall not in any manner adversely affect Sublandlord's
other rights and remedies, including Sublandlord's right to evict Subtenant and
to recover damages. Subtenant shall have no right to notice under Official Code
of Georgia Annotated Section 44-7-7 of the termination of its tenancy. The

Furniture, in "As-Is" "WHERE-IS" condition as of the date of this Sublease.

warranties with respect to the Furniture or the condition of the Subleased
Premises. At the expiration or earlier termination of the Term, Subtenant shall
leave the Subleased Premises in good condition and repair, ordinary wear and
tear excepted, vacant and broom clean condition, remove the Furniture, any
personal property, other furniture and trade fixtures which it owns or leases
from third parties, and any alterations as requested by Sublandlord, and

hereof. Subtenant shall pay Sublandlord for the cost to restore any damage
caused by such removal. Any personal property and trade fixtures used by

contains the entire agreement between the parties and all prior negotiations and
agreements are merged into this Sublease. This Sublease is the result of
negotiations between knowledgeable parties and their respective attorneys;

thereof to be drafted. This Sublease may not be modified or terminated, nor any
of its provisions waived except by a written instrument executed by all parties.

         26. INDEMNIFICATION.

affiliates, and their officers directors, shareholders and partners
("Indemnities"), from and against any claim, demand, liability, loss, fine,
penalties, cost and expense (including, but not limited to, attorneys' fees and
disbursements) imposed on, incurred by, or asserted against the Indemnities as a
result of (a) any breach of Subtenant of this Sublease or the Prime Lease, (b)
any personal injury or property damage arising out of Subtenant's or Subtenant's
agents', visitors' employees', contractors' or representatives' use of the
Subleased Premises or Building, and (c) any breach or noncompliance by Subtenant
or Subtenant's agents, visitors, employees, contractors, and representatives of
any Legal Requirements affecting the use or occupancy of the Subleased Premises.

covenant or condition on the part of Sublandlord to be performed thereunder.
Sublandlord covenants and agrees that during the term of this Sublease it shall

surrendered or terminated.

         (b)      Notwithstanding anything to the contrary contained in this
Sublease, in the event that the consent or approval of Sublandlord is required
