      SUPPLEMENTAL REGISTRATION RIGHTS AND LOCK-UP AGREEMENT


           THIS  SUPPLEMENTAL  REGISTRATION  RIGHTS AND LOCK-UP  AGREEMENT (this
"Agreement")  is made and entered into as of July 1, 1997, by and among COLONIAL
PROPERTIES  TRUST,  an Alabama  real estate  investment  trust (the  "Company"),
Colonial  Realty  Limited  Partnership,  a  Delaware  limited  partnership  (the
"Operating Partnership"), and COLONIAL COMMERCIAL INVESTMENTS, INC. ("CCI").

           WHEREAS, on September 29, 1993 the Company, Colonial Properties, Inc.
(of which  CCI is the  successor)  and  certain  other  parties  entered  into a
Registration Rights and Lock-up Agreement (the "Initial  Agreement") pursuant to
which the Company granted to certain holders of Units (as defined in the Initial
Agreement) of the Operating  Partnership certain  registration  rights, and such
holders agreed to certain lock-up arrangements;

           WHEREAS,  on July 1, 1996, CCI and certain other parties entered into
a  Supplemental  Registration  Rights and  Lock-Up  Agreement  pursuant to which
certain  additional  Units  became  subject to the terms and  conditions  of the
Initial Agreement;

           WHEREAS,  on the date  hereof,  CCI is or will  become  the  owner of
27,275 Units (the  "Additional  Units") in  connection  with the transfer to the
Operating Partnership of the Timothy Woods Apartments; and

           WHEREAS,  the  parties  hereto  have  agreed  that,  except as stated
herein,  the Additional  Units shall be subject to, and the parties hereto shall
be governed by, the terms and conditions of the Initial Agreement.

           NOW,   THEREFORE,   the  parties  hereto,  in  consideration  of  the
foregoing,  the mutual covenants and agreements hereinafter set forth, and other
good and valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, agree as follows:

           1.   General.

                1(a) Except as otherwise  defined herein,  all capitalized terms
used herein shall have the meanings ascribed to them in the Initial Agreement.

                1(b) Except as otherwise  provided  herein,  CCI and the Company
shall have all of the  rights and  obligations  with  respect to the  Additional
Units as are  provided for in the Initial  Agreement  with respect to the Common
Shares and Units expressly referred to therein.  Nothing in this Agreement shall
be deemed to amend,  waive,  supplement,  or  otherwise  affect the terms of the
Initial Agreement.

           2.   Definitions.

           Except as otherwise provided herein,

                2(a) The  Additional  Units shall be deemed "Units" as that term
is  defined  in the  Initial  Agreement,  and  any  Common  Shares  issued  upon
redemption of Additional  Units shall be deemed "Shares" as that term is defined
in the Initial  Agreement.  The Additional  Units and any Common Shares issuable
upon redemption of Additional Units are referred to herein  collectively as "New
Securities."

                2(b) Any Common Shares issued upon the  redemption of Additional
Units shall be deemed  "Registrable  Securities"  as that term is defined in the
Initial Agreement.

                2(c)  CCI and its  permitted  successors  and  assigns  shall be
deemed  "Holders" as that term is defined in the Initial  Agreement and shall be
referred to as Holders herein.

           3.   Lock-up Agreement.

                3(a)  Notwithstanding  any other  provision of this Agreement or
the Initial  Agreement,  the Holder hereby  agrees that,  except as set forth in
Section 3(b) below,  for a period of one year from the date hereof (the "Lock-up
Period"),  without the prior written consent of the Company,  it will not offer,
pledge,  sell,  contract to sell, grant any options for the sale of or otherwise
dispose  of,  directly  or  indirectly  (collectively,  "Dispose  of"),  any New
Securities (the "Lock-up").

                3(b) The  following  transfers  of New  Securities  shall not be
subject to the Lock-up set forth in Section 2(a):

                     (i)  a Holder may Dispose of New Securities
                as a gift or other transfer without consideration;

                     (ii) a Holder who is a natural  person  may  Dispose of New
                Securities  to his  or  her  spouse,  siblings,  parents  or any
                natural  or  adopted  children  or other  descendants  or to any
                personal  trust in which  such  family  members  or such  Holder
                retain the entire beneficial interest;

                     (iii)a  Holder may Dispose of New  Securities to any entity
                that controls, is controlled by, or is under common control with
                such Holder;

                     (iv) a Holder may Dispose of New  Securities  pursuant to a
                pledge, grant of security interest or other encumbrance effected
                in a bona fide  transaction  with an unrelated and  unaffiliated
                pledgee; and

                     (v) at the election of the Company, a Holder may Dispose of
                New Securities in an underwritten public offering.

           In the event a Holder  Disposes of New  Securities  described in this
Section 3(b) (except pursuant to clause (iv) hereof),  such New Securities shall
remain  subject to this  Agreement  and, as a condition  of the validity of such
disposition,  the  transferee  shall  be  required  to  execute  and  deliver  a
counterpart  of this  Agreement  (except that a pledgee shall not be required to
execute and deliver a counterpart  of this  Agreement  until it forecloses  upon
such New Securities). Thereafter, such transferee shall be deemed to be a Holder
for purposes of this Agreement.

           4.   Shelf Registration Under the Securities Act.

                Beginning  after  the  expiration  of the  Lock-up  Period,  the
Holder(s)  shall be  entitled  to  offer  for sale  pursuant  to a  Registration
Statement any Registrable Securities held by the Holder(s), subject to the terms
and conditions, and pursuant to the procedures, specified in Sections 3 and 4 of
the Initial Agreement.

           5.   Indemnification; Contribution.

                The parties agree to indemnify and hold  harmless,  with respect
to any registration of Registrable  Securities hereunder,  to the same extent as
specified in Section 5 of the Initial Agreement.

           6.   Rule 144 Sales.

                The  Company  covenants  to  undertake  all  such  steps  as are
specified in Section 6 of the Initial Agreement in order to enable any Holder to
sell Common  Shares  issued or issuable  upon  redemption  of  Additional  Units
pursuant to Rule 144 under the Securities Act.

           7.   Miscellaneous.

                7(a)  Amendments and Waivers.  The provisions of this Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given without the written consent of the Company and the Holders of a
majority in amount of the outstanding New Securities; provided, however, that no
amendment, modification or supplement or waiver or consent to the departure with
respect to the  provisions of Sections 3, 4, 5 or 6 hereof shall be effective as
against  any Holder of New  Securities  unless  consented  to in writing by such
Holder of New Securities. Notice of any amendment, modification or supplement to
this Agreement shall be provided by the Company to each Holder of New Securities
at least  thirty  (30)  days  prior  to the  effective  date of such  amendment,
modification or supplement.

                7(b) Notices;  Counterparts;  Headings;  Successors and Assigns;
Specific  Performance;  Governing  Law.  The parties  agree to be governed  with
respect to the subject  matter  hereof by the  provisions  set forth in Sections

                7(c) Entire Agreement. This Agreement is intended by the parties
as a final  expression of their agreement with respect to the New Securities and
is  intended to be a complete  and  exclusive  statement  of the  agreement  and
understanding  of the parties hereto in respect of the subject matter  contained
herein.  This  Agreement  supersedes  all prior  agreements  and  understandings
