         POST APARTMENT HOMES, L.P., a Georgia limited partnership (the
"Issuer," which term includes any successor under the Indenture hereinafter
referred to), for value received, hereby promises to pay to Cede & Co. or its
registered assigns (the "Holder"), upon presentation, the principal sum of
TWENTY-FIVE MILLION DOLLARS ($25,000,000) on June 18, 2007 (the "Maturity
Date"), and to pay interest on the outstanding principal amount thereon from
June 18, 2002, or from the most recent interest payment date to which interest
has been paid or duly provided for, semi-annually in arrears on June 18 and
December 18 of each year (each an "Interest Payment Date"), commencing December
18, 2002, and at the Stated Maturity, at the rate of 6.11% per annum, computed
on the basis of a 360-day year comprised of twelve 30-day months, until the
entire principal amount hereof is paid or duly provided for. The interest so
payable, and punctually paid or duly provided for on any Interest Payment Date
will, as provided in the Indenture (hereinafter defined), be paid to the person
in whose name this Note (the "Note") (or one or more predecessor Notes) is

December 18 Interest Payment Date (each a "Regular Record Date"). Any such
interest not so punctually paid or duly provided for shall forthwith cease to
be payable to the Holder on such Regular Record Date, and may either be paid to
the Person in whose name this Note (or one or more predecessor Notes) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Notes not more than 15 days and not less than 10 days prior
to such Special Record Date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Notes may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture. Payments of the
principal and interest on, this Note will be made at the office or agency of
the Trustee (hereinafter defined) maintained for that purpose at c/o Harris
Trust Bank of New York, Wall Street Plaza, 88 Pine Street, 19th Floor, New
York, New York 10005, or elsewhere as provided in the Indenture, in United
States Dollars; provided, however, that at the option of the Issuer payment of
interest may be made by (i) check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register kept for the
Notes pursuant to Section 305 of the Indenture (the "Note Register") or (ii)
transfer to an account of the Person entitled thereto located inside the United
States. Payments of principal and interest in respect of this Note will be made
by wire transfer of immediately available funds, in such coin or currency as at
the time of payment is legal tender for the payment of public and private
debts, so long as this Note is in global form as described in Section 203 of
the Indenture. If this Note is not in global form, all such payments will be
made by wire transfer of immediately available funds if the Holder hereof at
the applicable record date shall have provided wire transfer instructions to
the Trustee, received by the Trustee no later than 15 days prior to the
applicable payment date, and otherwise payment shall be made in accordance with
Section 307 of the Indenture. Such wire transfer instructions shall remain in
effect until revoked in a writing received by the Trustee from the Holder
hereof.

         This Note is one of a fully authorized issue of securities of the
Issuer issued under an Indenture, dated as of September 15, 2000 (the
"Indenture"), as supplemented by the First Supplemental Indenture among the
Issuer and Sun Trust Bank, (the "Trustee," which term includes any successor
trustee under the Indenture with respect to the Notes), to which Indenture and
all indentures supplemental thereto reference is hereby made for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Issuer, the Trustee and Holders of the Notes, and of the terms upon
which the Notes are, and are to be, authenticated and delivered. This Note is
one of the series designated as the "6.11% Notes due 2007," limited in the
aggregate principal amount to $25,000,000.

         The Indenture contains provisions for defeasance at any time of (a)
the entire indebtedness of the Issuer on this Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Issuer, in each case, upon compliance by the Issuer with certain conditions set
forth in the Indenture, which provisions apply to this Note.

         In addition to the covenants of the Issuer contained in the Indenture,
the Issuer makes the following covenants with respect to, and for the benefit
of the Holders of, the Notes:


                                       2
<PAGE>


                  Limitations On Incurrence of Debt. The Issuer will not, and
         will not permit a Subsidiary to, incur any Debt (as defined below),
         other than intercompany Debt (representing Debt to which the only
         parties are Post Properties, Inc., a Georgia corporation (the
         "Company"), the Issuer and any Subsidiaries, but only so long as such
         Debt is held solely by any of the Company, the Issuer and any
         Subsidiary), if, immediately after giving effect to the incurrence of
         such additional Debt, the aggregate principal amount of all
         outstanding Debt of the Issuer and its Subsidiaries on a consolidated
         basis determined in accordance with generally accepted accounting
         principles is greater than 60% of the sum of (i) Total Assets (as
         defined below) as of the end of the fiscal quarter covered in the
         Issuer's Annual Report on Form 10-K or Quarterly Report on Form 10-Q,
         as the case may be, most recently filed with the Securities and
         Exchange Commission (or, if such filing is not permitted under the
         Securities Exchange Act of 1934, as amended, with the Trustee) prior
         to the incurrence of such additional Debt and (ii) the increase in
         Total Assets from the end of such quarter including, without
         limitation, any increase in Total Assets resulting from the incurrence
         of such additional Debt (such increase together with the Issuer's
         Total Assets is referred to as the "Adjusted Total Assets").

                  In addition to the foregoing limitation on the incurrence of
         Debt, the Issuer will not, and will not permit any Subsidiary to,
         incur any Secured Debt other than intercompany Debt if, immediately
         after giving effect to the incurrence of such additional Secured Debt,
         the aggregate principal amount of all outstanding Secured Debt of the
         Issuer and its Subsidiaries on a consolidated basis is greater than
         40% of Adjusted Total Assets. Debt shall be deemed to be "incurred" by
         the Issuer and its Subsidiaries on a consolidated basis whenever the
         Issuer and its Subsidiaries on a consolidated basis shall create,
         assume, guarantee or otherwise become liable in respect thereof.

                  In addition to the foregoing limitations on the incurrence of
         Debt, the Issuer will not, and will not permit any Subsidiary to,
         incur any Debt, other than intercompany Debt, if the ratio of
         Consolidated Income Available for Debt Service to the Annual Debt
         Service Charge (in each case as defined below) for the period
         consisting of the four consecutive fiscal quarters most recently ended
         prior to the date on which such additional Debt is to be incurred
         shall have been less than 1.5 to 1, on a pro forma basis after giving
         effect to the incurrence of such Debt and to the application of the
         proceeds therefrom, and calculated on the assumption that (i) the
         incurrence of such Debt and any other Debt by the Issuer or its
         Subsidiaries since the first day of such four-quarter period and the
         application of the proceeds therefrom, including to refinance other
         Debt, had occurred at the beginning of such period, (ii) the repayment
         or retirement of any other Debt by the Issuer or its Subsidiaries
         since the first day of such four-quarter period had been repaid or
         retired at the beginning of such period (except that, in making such
         computation, the amount of Debt under any revolving credit facility
         shall be computed based upon the average daily balance of such Debt
         during such period), and (iii) in the case of any increase or decrease
         in Total Assets, or any other acquisition or disposition by the Issuer
         or any Subsidiary of any asset or group of assets, since the first day
         of such four-quarter period, including, without limitation, by merger,
         stock purchase or sale, or asset purchase or sale, such increase,
         decrease or other acquisition or disposition or any related


                                       3
<PAGE>


         repayment of Debt had occurred as of the first day of such period with
         the appropriate adjustments to net income and Debt levels with respect
         to such increase, decrease or other acquisition or disposition being
         included in such pro forma calculation. For purposes of the
         adjustments referred to in clause (iii) of the preceding sentence, any
         income earned (or loss incurred) as a result of any such increase,
         decrease or other acquisition or disposition referred to in clause
         (iii) for a period less than such four-quarter period shall be
         annualized for such four-quarter period.

                  Maintenance of Total Unencumbered Assets. The Issuer is
         required to maintain Total Unencumbered Assets of not less than 150%
         of the aggregate outstanding principal amount of the outstanding
         Unsecured Debt of the Issuer.

         taxes and other non-cash items, (vi) charges resulting from a change
         in accounting principles, and (vii) charges for early extinguishment
         of debt, and less amounts which have been added in determining
         Consolidated Net Income during such period for (a) provisions for
         gains from sales or joint ventures, and (b) decreases in deferred
         taxes and other non-cash items.

                  "Consolidated Interest Expense" means, for any period, and
         without duplication, all interest (including the interest component of
         rentals on capitalized leases, letter of credit fees, commitment fees
         and other like financial charges) and all amortization of debt
         discount on all Debt (including, without limitation, payment-in-kind,
         zero coupon and other like securities) of the Issuer and its
         Subsidiaries, but excluding legal fees, title insurance charges and
         other out-of-pocket fees and expenses incurred in connection with the
         issuance of Debt, all determined in accordance with generally accepted
         accounting principles.

                  "Consolidated Net Income" for any period means the amount of
         consolidated net income (or loss) of the Issuer and its Subsidiaries

                  "Debt" of the Issuer or any Subsidiary means any indebtedness
         of the Issuer and its Subsidiaries, whether or not contingent, in
         respect of (i) borrowed money evidenced by bonds, notes, debentures or
         similar instruments, (ii) indebtedness secured by a mortgage, pledge,
         lien, charge, encumbrance or any security interest existing on
         property owned by the Issuer and its Subsidiaries, (iii) the
         reimbursement obligations, contingent

         property by the Issuer and its Subsidiaries as lessee which is

         the case of items of indebtedness under (i) through (iii) above to the
         extent that any such items (other than letters of credit) would appear
         as a liability on the Issuer's consolidated balance sheet in
         accordance with generally accepted accounting principles, and also
         includes, to the extent not otherwise included, any obligation by the
         Issuer or any Subsidiary to be liable for, or to pay, as obligor,
         guarantor or otherwise (other than for purposes of collection in the
         ordinary course of business), indebtedness of another person (other
         than the Issuer or any Subsidiary) (it being understood that Debt
         shall be deemed to be incurred by the Issuer and its Subsidiaries on a
         consolidated basis whenever the Issuer and its Subsidiaries on a
         consolidated basis shall create, assume, guarantee or otherwise become
         liable in respect thereof); provided, however, that the term Debt
         shall not include any such indebtedness that has been the subject of
         an "in substance" defeasance in accordance with generally accepted
         accounting principles.

                  "Secured Debt" means Debt secured by any mortgage, trust

         majority of the shares of the non-voting capital stock or other

the Notes may be declared, and upon such declaration shall become, due and
payable in the manner and with the effect provided in the Indenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Note shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Notes, the Holders of not less than 25% in principal amount of the Notes at the
time Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee and
offered the Trustee reasonable indemnity and the Trustee shall not have
received from the Holders of a majority in principal amount of the Notes at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Note for the enforcement of any payment
of principal hereof or any interest on or after the respective due dates
expressed herein.

         Neither the Company, Post GP Holdings nor any other partner of the
Issuer shall have any obligation or liability for payment of the Notes, and
holders of the Notes will have no claims or other recourse against the Company,
Post GP Holdings or any other partner of the Issuer, or against any assets of
the Company, Post GP Holdings or any other partner of the Issuer, in respect of
the Notes; and the holders of the Notes shall not have any right to enforce any
obligation of a partner to make a contribution to the Issuer under any
provision of the Agreement of Limited Partnership. Neither the Company, Post GP
Holdings nor any other partner of the Issuer nor any of their respective assets
shall be subject to any lien, levy, execution or any other enforcement
procedure relating directly or indirectly to the Notes or any obligations
hereunder; provided, however, that in the event of a dissolution of the Issuer,
any assets of the Issuer that are received by the Company or Post GP Holdings
in such dissolution shall be subject to the claims of the holders of the Notes
for the enforcement of payment thereof. The Issuer covenants that Post GP
Holdings shall not acquire any assets other than interests in the Issuer and
other than


                                       6
<PAGE>


such bank accounts or similar instruments or accounts as necessary to carry out
its responsibilities under the Agreement of Limited Partnership of the Issuer
without the prior written consent of a majority in principal amount of all of
the outstanding Notes. A breach of the foregoing covenant by the Issuer, and
continuance of such breach for a period of 60 days after there has been given,
by registered or certified mail, to the Issuer by the Trustee or to the Issuer
and the Trustee by the holders of at least 25% in principal amount of the
outstanding Notes a written notice as set forth in the Indenture, shall be an
event of default under the Indenture.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Notes under the Indenture at any
time by the Issuer and the Trustee with the consent of the Holders of not less
than a majority in principal amount of the Outstanding Notes. The Indenture
also contains provisions permitting the Holders of not less than a majority in
principal amount of the Notes at the time Outstanding, on behalf of the Holders
of all Notes, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Note shall be conclusive and
binding upon such Holder and upon all future Holders of this Note and of any
Note issued upon the registration of transfer hereof or in exchange hereof or
in lieu hereof, whether or not notation of such consent or waiver is made upon
this Note.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on, this Note at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Note is registrable in the Note
Register, upon surrender of this Note for registration of transfer at the
office or agency of the Issuer in any Place of Payment where the principal of,
premium, if any, and interest on, this Note are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Issuer and the Security Registrar for the Notes duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereon one or more
Notes of this series, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

         The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Notes are
exchangeable for a like aggregate principal amount of Notes of this series of a
different authorized denomination, as requested by the Holder surrendering the
same.

         No service charge shall be made for any registration of transfer or
exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.
