                           (i) No Event of Default nor an event or condition

         lender for such disbursement at least ten (10) days prior to the

         "Interest Rate" appearing in the Note shall be deemed to mean the

         portion of the payments for the first and last months of the term of
         the Loan, if such payments pertain to partial months, shall be
         calculated on the basis of the actual number of days that the Loan is
         outstanding in such partial months over a 365 day or 366 day year, as
         applicable.

                  (d) PAYMENT OF PRINCIPAL AND INTEREST. The parties acknowledge

<PAGE>

                           (i) Interest only in the amount of $338,550.00 per
         month shall be paid monthly in arrears on the first day of each month
         beginning February 1, 2005 and continuing on the first day of each

         February 1, 2010, the Borrower shall pay monthly installments of
         principal and interest in the amount of $419,699.69 per month and
         continuing on the first day of each month thereafter until the Maturity
         Date.

                  (e) PREPAYMENT. Sections 8 and 9 of the Note are hereby
amended and restated to read as follows:

                           "8. PREPAYMENT. Borrower shall not have the right to
         prepay all or any portion of the Loan amount at any time during the
         term of this Note except as expressly set forth below or in the Deed To
         Secure Debt. This Note shall be closed to prepayment until February 1,
         2010. Commencing on February 1, 2010, the Loan may be prepaid in whole,
         but not in part, with the payment of a Prepayment Fee (as defined
         below). In addition, during the ninety (90) day period prior to the
         Maturity Date, Borrower may prepay the entire outstanding principal
         balance of the Loan, accrued interest and all other sums due and
         payable under the Loan Documents without Prepayment Fee. The Borrower
         must give at least thirty (30) days prior written notice of a
         prepayment. If Borrower provides notice of its intention to prepay, the
         Accelerated Loan Amount shall become due and payable on the date
         specified in the prepayment notice. In addition to the above
         limitations upon prepayment, this Note may not be prepaid without the
         simultaneous prepayment of the Other Notes in accordance with their
         terms.

                           9. DEFAULT; DEFAULT PREPAYMENT FEE; PREPAYMENT FEE.

                           (a) Any tender of payment by Borrower or any other
         person or entity of the Aggregate Indebtedness, other than as expressly
         provided in the Loan Documents, shall constitute a prohibited
         prepayment. If a prepayment of all or any part of the Aggregate
         Indebtedness is made (i) following an Event of Default and an
         acceleration of the Maturity Date, (ii) following the application of
         money to the principal of the Loan after a casualty or a condemnation,
         or (iii) in connection with a purchase of the Property at foreclosure
         or by deed in lieu of foreclosure or by power of sale or a repayment of
         the Aggregate Indebtedness at any time before, during or after, a
         judicial or non-judicial foreclosure or sale of the Property, then to
         compensate Holder for the loss of the investment, Borrower shall pay an
         amount equal to the Default Prepayment Fee (as hereinafter defined);
         provided however, in the event of a casualty or condemnation, so long
         as Borrower makes a good faith effort to obtain an amount equal to the
         Default Prepayment Fee due as a result of the casualty or condemnation
         as part of its damages from the insurer or condemning authority, the
         Default Prepayment Fee due as a result of the casualty or condemnation
         shall be waived in the event that such amount is not collected by
         Borrower.

                           (b) The "Prepayment Fee" shall be the greater of (A)
         the Prepayment Ratio (as hereinafter defined) multiplied by the
         difference between (x) and (y), where (x) is the present value of all
         remaining payments of principal and interest including the outstanding
         principal due on the Maturity Date, discounted at the rate which, when
         compounded monthly, is equivalent to the Treasury Rate plus twenty-five
         hundredths percent (0.25%) compounded semi-annually, and (y) is the
         amount of the principal then outstanding, or (B) one-half of one
         percent (0.50%) of the amount of the principal being prepaid.

                           (c) The "TREASURY RATE" shall be the annualized yield
         on securities issued by the United States Treasury having a maturity
         equal to the remaining stated term of this Note, as quoted in the
         FEDERAL RESERVE STATISTICAL RELEASE [H. 15 (519)] under the heading
         "U.S. Government Securities - Treasury Constant Maturities" for the
         date on which prepayment is being made. If this rate is not available

                                       3
<PAGE>

         as of the date of prepayment, the Treasury Rate shall be determined by
         interpolating between the yield on securities of the next longer and
         next shorter maturity. If the Treasury Rate is no longer published,
         Holder shall select a comparable rate. Holder will, upon request,
         provide an estimate of the amount of the Prepayment Fee two weeks
         before the date of the scheduled prepayment.

                           (d) The "PREPAYMENT RATIO" shall be a fraction, the
         numerator of which shall be the amount of principal being prepaid, and
         the denominator of which shall be the principal then outstanding.

                  (e) Any reference to "Default Prepayment Fee" shall be deemed
         to mean the "Prepayment Fee".

                [End of Amended and Restated Paragraphs 8 and 9]

                  (f) INTEREST RATE PROTECTION. Effective January 1, 2005, the
         Interest Rate Protection provisions of Section 21 of the Note shall no
         longer be applicable to this Note, as a result of the change to a fixed
         rate of interest.

                  (g) REFERENCE TO LOAN DOCUMENTS. All references in the Note to
the terms "Deed to Secure Debt", "Guaranty", "Other Notes", "Loan Documents", or
"Indemnity Agreement" or to any individual document constituting a Loan
Document, shall be deemed to include the modifications thereto effected by the
Modification Agreement, together with any modifications, renewals or extensions
hereafter made with respect thereto.

         5. LEASE ROLLOVER RESERVE. In the event Alston & Bird ("Alston & Bird")
either (x) does not renew the Alston & Bird Lease (as defined below) or (y)
reduces its then rentable square footage leased by Alston & Bird from that
currently leased under the Alston & Bird Lease, then Borrower shall within 10
business days following the earlier of (i) Alston & Bird's notification date
under the Alston & Bird Lease or (y) the date of such non-renewal or reduction,
provide the holders of the Notes (collectively, "Lender") with a letter of
credit, in form and substance acceptable to Lender, in an amount equal to the
reduced rentable square footage multiplied by $30.00 per rentable square foot.
To the extent Borrower subsequently re-leases a portion of the space which was
previously rented under the Alston & Bird lease to a tenant approved by Lender
(if such approval is required under the terms of the Loan Documents) under a
Lease approved by Lender (if such approval is required under the terms of the
Loan Documents), then the required Letter of Credit amount will be reduced by
the lesser of (i) the actual leasing costs (tenant improvements and leasing
commissions) for the re-leased space or (ii) $30.00 per rentable square foot of
the re-leased space.

         6. NO IMPAIRMENT OF SECURITY, ETC. It is mutually agreed by and between
the parties hereto that this Agreement shall become a part of the Note by
reference and that nothing herein contained shall impair the security now held
for the indebtedness, nor shall waive, annul, vary or affect any provision,
condition, covenant or agreement contained in the Note, except as herein
amended, nor affect or impair any rights, powers or remedies under the Note, as
hereby amended. Furthermore, the Holder does hereby reserve all rights and
remedies it may have as against all parties who may hereafter become secondarily
liable for the repayment of the indebtedness evidenced by the Note.

         7. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of any assignee or the respective heirs, executors,
administrators, successors and assigns of the parties hereto.

         8. COUNTERPARTS. This Agreement may be executed in multiple
counterparts and/or by the use of multiple signature pages, each of which shall
constitute an original but all of which, taken together, shall constitute one
and the same instrument.

                                       4

         IN WITNESS WHEREOF, this Agreement has been executed by the parties
hereto under seal and delivered as of the day and year first above written.

                  (c) INTEREST RATE. The Interest Rate set forth in Section 1(a)
of the Note shall continue to apply until January 1, 2005. Effective January 1,
2005, the Interest Rate on the Note shall be a fixed rate as follows:

                           (i) Interest on the Note shall accrue from and after
         January 1, 2005 at a fixed rate of 5.49% per annum and the defined term
         "Interest Rate" appearing in the Note shall be deemed to mean the
         aforesaid rate of 5.49% per annum from and after January 1, 2005.

                           (ii) Prior to January 1, 2005, interest shall be
         calculated on the basis of the actual number of days elapsed over a
         three hundred sixty (360) day year. From and after January 1, 2005,
         interest shall be calculated on the basis of a thirty (30) day month
         and a three hundred sixty (360) day year, except that the interest
         portion of the payments for the first and last months of the term of
         the Loan, if such payments pertain to partial months, shall be
         calculated on the basis of the actual number of days that the Loan is
         outstanding in such partial months over a 365 day or 366 day year, as
         applicable.

                  (d) PAYMENT OF PRINCIPAL AND INTEREST. The parties acknowledge
and agree that the existing payment requirements for the Note as set forth in
Section 1(b) thereof shall continue to apply through the payment due on January
1, 2005, subject, however, to the suspension of principal payments as set forth
in Section 4(a) of the Assumption Agreement. In addition, any interest on the
future advance of principal shall be added to and included in the monthly
payments of interest required under the Note until and including January 1,
2005. From and after January 1, 2005, the following payments shall be made on
this Note, in lieu of the payments set forth in Section 1(b) of the Note:

                           (i) Interest only in the amount of $27,450.00 per
         month shall be paid monthly in arrears on the first day of each month
         beginning February 1, 2005 and continuing on the first day of each
         month thereafter through and including January 1, 2010. Commencing

                                       2
<PAGE>

         February 1, 2010, the Borrower shall pay monthly installments of
         principal and interest in the amount of $34,029.70 per month and
         continuing on the first day of each month thereafter until the Maturity
         Date.

                  (e) PREPAYMENT. Sections 8 and 9 of the Note are hereby
amended and restated to read as follows:

                           "8. PREPAYMENT. Borrower shall not have the right to
         prepay all or any portion of the Loan amount at any time during the
         term of this Note except as expressly set forth below or in the Deed To
         Secure Debt. This Note shall be closed to prepayment until February 1,
         2010. Commencing on February 1, 2010, the Loan may be prepaid in whole,
         but not in part, with the payment of a Prepayment Fee (as defined
         below). In addition, during the ninety (90) day period prior to the
         Maturity Date, Borrower may prepay the entire outstanding principal
         balance of the Loan, accrued interest and all other sums due and
         payable under the Loan Documents without Prepayment Fee. The Borrower
         must give at least thirty (30) days prior written notice of a
         prepayment. If Borrower provides notice of its intention to prepay, the
         Accelerated Loan Amount shall become due and payable on the date
         specified in the prepayment notice. In addition to the above
         limitations upon prepayment, this Note may not be prepaid without the
         simultaneous prepayment of the Other Notes in accordance with their
         terms.

                           9. DEFAULT; DEFAULT PREPAYMENT FEE; PREPAYMENT FEE.

                           (a) Any tender of payment by Borrower or any other
         person or entity of the Aggregate Indebtedness, other than as expressly
         provided in the Loan Documents, shall constitute a prohibited
         prepayment. If a prepayment of all or any part of the Aggregate
         Indebtedness is made (i) following an Event of Default and an
         acceleration of the Maturity Date, (ii) following the application of
         money to the principal of the Loan after a casualty or a condemnation,
         or (iii) in connection with a purchase of the Property at foreclosure
         or by deed in lieu of foreclosure or by power of sale or a repayment of
         the Aggregate Indebtedness at any time before, during or after, a
         judicial or non-judicial foreclosure or sale of the Property, then to
         compensate Holder for the loss of the investment, Borrower shall pay an
         amount equal to the Default Prepayment Fee (as hereinafter defined);
         provided however, in the event of a casualty or condemnation, so long
         as Borrower makes a good faith effort to obtain an amount equal to the
         Default Prepayment Fee due as a result of the casualty or condemnation
         as part of its damages from the insurer or condemning authority, the
         Default Prepayment Fee due as a result of the casualty or condemnation
         shall be waived in the event that such amount is not collected by
         Borrower.

                           (b) The "Prepayment Fee" shall be the greater of (A)
         the Prepayment Ratio (as hereinafter defined) multiplied by the
         difference between (x) and (y), where (x) is the present value of all
         remaining payments of principal and interest including the outstanding
         principal due on the Maturity Date, discounted at the rate which, when
         compounded monthly, is equivalent to the Treasury Rate plus twenty-five
         hundredths percent (0.25%) compounded semi-annually, and (y) is the
         amount of the principal then outstanding, or (B) one-half of one
         percent (0.50%) of the amount of the principal being prepaid.

                           (c) The "TREASURY RATE" shall be the annualized yield
         on securities issued by the United States Treasury having a maturity
         equal to the remaining stated term of this Note, as quoted in the
         FEDERAL RESERVE STATISTICAL RELEASE [H. 15 (519)] under the heading
         "U.S. Government Securities - Treasury Constant Maturities" for the
         date on which prepayment is being made. If this rate is not available
         as of the date of prepayment, the Treasury Rate shall be determined by
         interpolating between the yield on securities of the next longer and

                                       3
<PAGE>

         next shorter maturity. If the Treasury Rate is no longer published,
         Holder shall select a comparable rate. Holder will, upon request,
         provide an estimate of the amount of the Prepayment Fee two weeks
         before the date of the scheduled prepayment.

                           (d) The "PREPAYMENT RATIO" shall be a fraction, the
         numerator of which shall be the amount of principal being prepaid, and
         the denominator of which shall be the principal then outstanding.

                           (e) Any reference to "Default Prepayment Fee" shall
         be deemed to mean the "Prepayment Fee".

                [End of Amended and Restated Paragraphs 8 and 9]

                  (f) INTEREST RATE PROTECTION. Effective January 1, 2005, the
Interest Rate Protection provisions of Section 21 of the Note shall no longer be
applicable to this Note, as a result of the change to a fixed rate of interest.

                  (g) REFERENCE TO LOAN DOCUMENTS. All references in the Note to
the terms "Deed to Secure Debt", "Guaranty", "Other Notes", "Loan Documents", or
"Indemnity Agreement" or to any individual document constituting a Loan
Document, shall be deemed to include the modifications thereto effected by the
Modification Agreement, together with any modifications, renewals or extensions
hereafter made with respect thereto.

         5. LEASE ROLLOVER RESERVE. In the event Alston & Bird ("Alston & Bird")
either (x) does not renew the Alston & Bird Lease (as defined below) or (y)
reduces its then rentable square footage leased by Alston & Bird from that
currently leased under the Alston & Bird Lease, then Borrower shall within 10
business days following the earlier of (i) Alston & Bird's notification date
under the Alston & Bird Lease or (y) the date of such non-renewal or reduction,
provide the holders of the Notes (collectively, "Lender") with a letter of
credit, in form and substance acceptable to Lender, in an amount equal to the
reduced rentable square footage multiplied by $30.00 per rentable square foot.
To the extent Borrower subsequently re-leases a portion of the space which was
previously rented under the Alston & Bird lease to a tenant approved by Lender
(if such approval is required under the terms of the Loan Documents) under a
Lease approved by Lender (if such approval is required under the terms of the
Loan Documents), then the required Letter of Credit amount will be reduced by
the lesser of (i) the actual leasing costs (tenant improvements and leasing
commissions) for the re-leased space or (ii) $30.00 per rentable square foot of
the re-leased space.

         6. NO IMPAIRMENT OF SECURITY, ETC. It is mutually agreed by and between
the parties hereto that this Agreement shall become a part of the Note by
reference and that nothing herein contained shall impair the security now held
for the indebtedness, nor shall waive, annul, vary or affect any provision,
condition, covenant or agreement contained in the Note, except as herein
amended, nor affect or impair any rights, powers or remedies under the Note, as
hereby amended. Furthermore, the Holder does hereby reserve all rights and
remedies it may have as against all parties who may hereafter become secondarily
liable for the repayment of the indebtedness evidenced by the Note.

         7. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of any assignee or the respective heirs, executors,
administrators, successors and assigns of the parties hereto.

         8. COUNTERPARTS. This Agreement may be executed in multiple
counterparts and/or by the use of multiple signature pages, each of which shall
constitute an original but all of which, taken together, shall constitute one
and the same instrument.
