Goldman, Sachs & Co.,
85 Broad Street,
New York, New York 10004.

To the Representatives of the several
Underwriters named in the respective
Pricing Agreements hereinafter described.


Ladies and Gentlemen:

     From time to time Weeks Realty, L.P., a Georgia limited partnership (the
"Company"), proposes to enter into one or more Pricing Agreements (each a
"Pricing Agreement") in the form of Annex I hereto, with such additions and
deletions as the parties thereto may determine, and, subject to the terms and
conditions stated herein and therein, to issue and sell to the firms named in
Schedule I to the applicable Pricing Agreement (such firms constituting the
"Underwriters" with respect to such Pricing Agreement and the securities
specified therein) certain of its debt securities (the "Securities") specified
in Schedule II to such Pricing Agreement (with respect to such Pricing
Agreement, the "Designated Securities").

     The terms and rights of any particular issuance of Designated Securities
shall be as specified in the Pricing Agreement relating thereto and in or
pursuant to the indenture (the "Indenture") identified in such Pricing
Agreement.

     1.  Particular sales of Designated Securities may be made from time to time
to the Underwriters of such Securities, for whom the firms designated as
representatives of the Underwriters of such Securities in the Pricing Agreement
relating thereto will act as representatives (the "Representatives").  The term
"Representatives" also refers to a single firm acting as sole representative of
the Underwriters and to an Underwriter or Underwriters who act without any firm
being designated as its or their representatives.  This Underwriting Agreement
shall not be construed as an obligation of the Company to sell any of the
Securities or as an obligation of any of the Underwriters to purchase any of the
Securities.  The obligation of the Company to issue and sell any of the
Securities and the obligation of any of the Underwriters to purchase any of the
Securities shall be evidenced by the Pricing Agreement with respect to the

                                       1
<PAGE>
 
Designated Securities specified therein.  Each Pricing Agreement shall specify
the aggregate principal amount of such Designated Securities, the initial public
offering price of such Designated Securities, the purchase price to the
Underwriters of such Designated Securities, the names of the Underwriters of
such Designated Securities, the names of the Representatives of such
Underwriters and the principal amount of such Designated Securities to be
purchased by each Underwriter and the commission, if any, payable to the
Underwriters with respect thereto and shall set forth the date, time and manner
of delivery of such Designated Securities and payment therefor.  The Pricing
Agreement shall also specify (to the extent not set forth in the Indenture and
the registration statement and prospectus with respect thereto) the terms of
such Designated Securities.  A Pricing Agreement shall be in the form of an
executed writing (which may be in counterparts), and may be evidenced by an
exchange of telegraphic communications or any other rapid transmission device
designed to produce a written record of communications transmitted.  The
obligations of the Underwriters under this Agreement and each Pricing Agreement
shall be several and not joint.

     2.  The Company represents and warrants to, and agrees with, each of the
Underwriters that:

          (a) A registration statement on Form S-3 (File No. 333-32755) in
     respect of the Securities has been filed with the Securities and Exchange
     Commission (the "Commission"); such registration statement and any post-
     effective amendment thereto, each in the form heretofore delivered or to be
     delivered to the Representatives and, excluding exhibits to such
     registration statement, but including all documents incorporated by
     reference in the prospectus contained therein, to the Representatives for
     each of the other Underwriters, have been declared effective by the
     Commission in such form; other than a registration statement, if any,
     increasing the size of the offering (a "Rule 462(b) Registration
     Statement"), filed pursuant to Rule 462(b) under the Securities Act of 1933
     (the "Act"), which became effective upon filing, no other document with
     respect to such registration statement or document incorporated by
     reference therein has heretofore been filed or transmitted for filing with
     the Commission (other than prospectuses filed pursuant to Rule 424(b) of
     the rules and regulations of the Commission under the Act, each in the form
     heretofore delivered to the Representatives); and no stop order suspending
     the effectiveness of such registration statement, any post-effective
     amendment thereto or the Rule 462(b) Registration Statement, if any, has
     been issued and no proceeding for that purpose has been initiated or
     threatened by the Commission (any preliminary prospectus included in such
     registration statement or filed with the Commission pursuant to Rule 424(a)
     under the Act, is hereinafter called a "Preliminary Prospectus"); the
     various parts of such registration statement, any post-effective amendment
     thereto or the Rule 462(b) Registration Statement, including all exhibits
     thereto and the documents incorporated by reference in the prospectus
     contained in the registration statement at the time such part of the
     registration statement became effective but excluding Form T-1, each as
     amended at the time such part of the registration statement became
     effective or such part of the Rule 462(b) Registration Statement, if any,
     became or hereafter becomes effective, are hereinafter collectively called
     the "Registration Statement"; the prospectus relating to the Securities, in

                                      -2-
<PAGE>
 
     the form in which it has most recently been filed, or transmitted for
     filing, with the Commission on or prior to the date of this Agreement,
     being hereinafter called the "Prospectus"; any reference herein to any
     Preliminary Prospectus or the Prospectus shall be deemed to refer to and
     include the documents incorporated by reference therein pursuant to the
     applicable form under the Act, as of the date of such Preliminary
     Prospectus or Prospectus, as the case may be; any reference to any
     amendment or supplement to any Preliminary Prospectus or the Prospectus
     shall be deemed to refer to and include any documents filed after the date
     of such Preliminary Prospectus or Prospectus, as the case may be, under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
     incorporated by reference in such Preliminary Prospectus or Prospectus, as
     the case may be; any reference to any amendment to the Registration
     Statement shall be deemed to refer to and include any annual report of the
     Company filed pursuant to Section 13(a) or 15(d) of the Exchange Act after
     the effective date of the Registration Statement that is incorporated by
     reference in the Registration Statement; and any reference to the
     Prospectus as amended or supplemented shall be deemed to refer to the
     Prospectus as amended or supplemented in relation to the applicable
     Designated Securities in the form in which it is filed with the Commission
     pursuant to Rule 424(b) under the Act in accordance with Section 5(a)
     hereof, including any documents incorporated by reference therein as of the
     date of such filing;

          (b) The documents incorporated by reference in the Prospectus, when
     they became effective or were filed with the Commission, as the case may
     be, conformed in all material respects to the requirements of the Act or
     the Exchange Act, as applicable, and the rules and regulations of the
     Commission thereunder, and none of such documents contained an untrue
     statement of a material fact or omitted to state a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading; and any further documents so filed and incorporated by
     reference in the Prospectus or any further amendment or supplement thereto,
     when such documents become effective or are filed with the Commission, as
     the case may be, will conform in all material respects to the requirements
     of the Act or the Exchange Act, as applicable, and the rules and
     regulations of the Commission thereunder and will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading; provided, however, that this representation and warranty shall
     not apply to any statements or omissions made in reliance upon and in
     conformity with information furnished in writing to the Company by an
     Underwriter of Designated Securities through the Representatives expressly
     for use in the Prospectus as amended or supplemented relating to such
     Securities;

          (c) The Registration Statement and the Prospectus conform, and any
     further amendments or supplements to the Registration Statement or the
     Prospectus will conform, in all material respects to the requirements of
     the Act and the Trust Indenture Act of 1939, as amended (the "Trust
     Indenture Act"), and the rules and regulations of the Commission thereunder

                                      -3-

     and do not and will not, as of the applicable effective date as to the
     Registration Statement and any amendment thereto and as of the applicable
     filing date as to the Prospectus and any amendment or supplement thereto,
     contain an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company
     by an Underwriter of Designated Securities through the Representatives
     expressly for use in the Prospectus as amended or supplemented relating to

               (xiv)  The Designated Securities have been duly authorized,

conferences with officers and other representatives of the Company and
representatives of the Underwriters and their counsel during which the contents
of the Registration Statement and Prospectus as amended or supplemented and
related matters were discussed and reviewed, and, although such counsel is not
passing upon and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Prospectus as amended or supplemented, except as set forth in
clause (xi) and (xiv) above and except for the statements concerning such firm
appearing under the caption "Legal Matters" therein, on the basis of the
information that was developed in the course of the performance of the service
referred to above, nothing has come to their attention that caused them to
believe that (i) the Registration Statement or any amendment thereto made prior
to such Time of Delivery (other than the financial statements and schedules and
the other financial data therein, as to which such counsel need express no
belief), at the time such Registration Statement or amendment became effective,
contained any untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, (ii) the Prospectus as amended or supplemented and any
further amendment or supplement thereto made prior to such Time of Delivery

any untrue statement of a material fact or omitted to state any material fact

                                      -17-

filed with the Commission, as the case may be, contained, in the case of a
registration statement which became effective under the Act, an untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or, in the
case of other documents which were filed under the Act or the Exchange Act with
the Commission, an untrue statement of a material fact or omitted to state a
material fact necessary in order to make the statements therein,in the light of
the circumstances under which they were made when such documents were so filed,

amendment to the Registration Statement required to be filed or of any contracts
or other documents of a character required to be filed as an exhibit to the
Registration Statement or required to be described in the Registration Statement
or the Prospectus which are not filed or described as required.

In rendering such opinion, such counsel may state that they express no opinion
as to the laws of any jurisdiction other than the laws of the State of Georgia
and the federal laws of the United States.

     substance satisfactory to the Representatives;

          (e) (i)  None of Weeks, the Company or any of their respective
     subsidiaries shall have sustained since the date of the latest audited

     Prospectus as amended prior to the date of the Pricing Agreement relating
     to the Designated Securities any loss or interference with its business
     from fire, explosion, flood or other calamity, whether or not covered by

     subsidiaries, otherwise than as set forth or contemplated in the Prospectus
     as amended or supplemented prior to the date of the Pricing Agreement
     relating to the Designated Securities, the effect of which, in any such
     case described in Clause (i) or (ii) above, is in the judgment of the
     Representatives so material and adverse as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Designated Securities on the terms and in the manner contemplated in the
     Prospectus as first amended or supplemented relating to the Designated
     Securities;

     declaration by the United States of a national emergency or war, if the
     effect of any such event specified in this Clause (iv) in the judgment of
     the Representatives makes it impracticable or inadvisable to proceed with
     the public offering or the delivery of the Designated Securities on the
     terms and in the manner contemplated in the Prospectus as first amended or
     supplemented relating to the Designated Securities;

          (h) The Company shall have complied with the provisions of Section
     5(c) hereof with respect to the furnishing of prospectuses on the New York
     Business Day next succeeding the date of the Pricing Agreement relating to

     shall have been duly listed, subject to notice of issuance, on the New York
     Stock Exchange.

     the Company herein at and as of such Time of Delivery, as to the
     performance by the Company of all of its obligations hereunder to be
     performed at or prior to such Time of Delivery, as to the matters set forth
     in subsections (a) and (f) of this Section and as to such other matters as

     or in which either Weeks or the Company or any of their subsidiaries owns

the Prospectus as amended or supplemented and any other prospectus relating to

information furnished to the Company by such Underwriter through the
Representatives expressly for use therein; and will reimburse the Company for
any legal or other expenses reasonably incurred by the Company in connection
with investigating or defending any such action or claim as such expenses are
incurred.

     (c) Promptly after receipt by an indemnified party under subsection (a) or
(b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection.  In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.  No indemnifying party shall, without the written
consent of the indemnified party, effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action or claim in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified party is an actual or potential
party to such action or claim) unless such settlement, compromise or judgment
(i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include any
statement as to or an admission of fault,culpability or a failure to act, by or
on behalf of any indemnified party.

     (d) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters of the Designated Securities
on the other from the offering of the Designated Securities to which such loss,
claim, damage or liability (or action in respect thereof) relates.  If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law or if the indemnified party failed to give the notice required
under subsection (c) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Underwriters of the Designated
Securities on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect

                                      -21-
<PAGE>
 
thereof), as well as any other relevant equitable considerations.  The relative
benefits received by the Company on the one hand and such Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from such offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by such Underwriters.
The relative fault of the Company on the one hand and the Underwriters on the
other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission t state a material fact relates to information supplied by the Company
on the one hand or such Underwriters on the other and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The Company and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this subsection (d)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (d).  The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the applicable Designated Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The obligations of the Underwriters of Designated
Securities in this subsection (d) to contribute are several in proportion to
their respective underwriting obligations with respect to such Securities and
not joint.

     (e) The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each partner of the Company and to each person, if any,
who controls the Company within the meaning of the Act.

     9.  (a)  If any Underwriter shall default in its obligation to purchase the
Designated Securities which it has agreed to purchase under the Pricing
Agreement relating to such Designated Securities, the Representatives may in
their discretion arrange for themselves or another party or other parties to
purchase such Designated Securities on the terms contained herein.  If within
thirty-six hours after such default by any Underwriter the Representatives do
not arrange for the purchase of such Designated Securities, then the Company
shall be entitled to a further period of thirty-six hours within which to

                                      -22-
<PAGE>
 
procure another party or other parties satisfactory to the Representatives to
purchase such Designated Securities on such terms.  In the event that, within
the respective prescribed period, the Representatives notify the Company that
they have so arranged for the purchase of such Designated Securities, or the
Company notifies the Representatives that it has so arranged for the purchase of
such Designated Securities, the Representatives or the Company shall have the
right to postpone the Time of Delivery for such Designated Securities for a
period of not more than seven days, in order to effect whatever changes may
thereby be made necessary in the Registration Statement or the Prospectus as
amended or supplemented, or in any other documents or arrangements, and the
Company agrees to file promptly any amendments or supplements to the
Registration Statement or the Prospectus which in the opinion of the
Representatives may thereby be made necessary.  The term "Underwriter" as used
in this Agreement shall include any person substituted under this Section with
like effect as if such person had originally been a party to the Pricing
Agreement with respect to such Designated Securities.

     (b) If, after giving effect to any arrangements for the purchase of the
Designated Securities of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate principal amount of such Designated Securities which remains
unpurchased does not exceed one-eleventh of the aggregate principal amount of
the Designated Securities, then the Company shall have the right to require each
non-defaulting Underwriter to purchase the principal amount of Designated
Securities which such Underwriter agreed to purchase under the Pricing Agreement
relating to such Designated Securities and, in addition, to require each non-
defaulting Underwriter to purchase its pro rata share (based on the principal
amount of Designated Securities which such Underwriter agreed to purchase under
such Pricing Agreement) of the Designated Securities of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

     (c) If, after giving effect to any arrangements for the purchase of the
Designated Securities of a defaulting Underwriter or Underwriters by the
Representatives and the Company as provided in subsection (a) above, the
aggregate principal amount of Designated Securities which remains unpurchased
exceeds one-eleventh of the aggregate principal amount of the Designated
Securities, as referred to in subsection (b) above, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Designated Securities of a defaulting Underwriter or
Underwriters, then the Pricing Agreement relating to such Designated Securities
shall thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company, except for the expenses to be borne by the Company
and the Underwriters as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any

                                      -23-
<PAGE>
 
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Securities.

     11.  If any Pricing Agreement shall be terminated pursuant to Section 9
hereof, the Company shall not then be under any liability to any Underwriter
with respect to the Designated Securities covered by such Pricing Agreement
except as provided in Sections 6 and 8 hereof; but, if for any other reason
Designated Securities are not delivered by or on behalf of the Company as
provided herein, the Company will reimburse the Underwriters through the
Representatives for all out-of-pocket expenses approved in writing by the
Representatives, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of such Designated Securities, but the Company shall then be under no
further liability to any Underwriter with respect to such Designated Securities
except as provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, the Representatives of the Underwriters of
Designated Securities shall act on behalf of each of such Underwriters, and the
parties hereto shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement: Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire, or telex constituting such
Questionnaire, which address will be supplied to the Company by the
Representatives upon request.  Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

     13.  This Agreement and each Pricing Agreement shall be binding upon, and
inure solely to the benefit of, the Underwriters, the Company and, to the extent
provided in Sections 8 and 10 hereof, the officers and directors of the Company
and each person who controls the Company or any Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement or any such Pricing Agreement.  No purchaser of any of the Securities
from any Underwriter shall be deemed a successor or assign by reason merely of
such purchase.

     14.  Time shall be of the essence of each Pricing Agreement.  As used
herein, "business day" shall mean any day when the Commission's office in
Washington, D.C.  is open for business and "New York Business Day" shall mean

                                      -24-
<PAGE>
 
each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which
banking institutions in New York are generally authorized or obligated by law or
executive order to close.

     15.  This Agreement and each Pricing Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

     16.  This Agreement and each Pricing Agreement may be executed by any one
or more of the parties hereto and thereto in any number of counterparts, each of
which shall be deemed to be an original, but all such respective counterparts
shall together constitute one and the same instrument.

                                      -25-

the Designated Securities which are the subject of this Pricing Agreement.  Each

Pursuant to Section 7(d) of the Underwriting Agreement, the accountants shall

     (i) They are independent certified public accountants with respect to the

Prospectus comply as to form in all material respects with the applicable
accounting requirements of the Act or the Exchange Act, as applicable, and the
related published rules and regulations thereunder; and, if applicable, they
have made a review in accordance with standards established by the American
Institute of Certified Public Accountants of the consolidated interim financial
statements, selected financial data, pro forma financial information, financial
forecasts and/or condensed financial statements derived from audited financial
statements of the Company for the periods specified in such letter, as indicated
in their reports thereon, copies of which have been separately furnished to the
representative or representatives of the Underwriters (the "Representatives")
such term to include an Underwriter or Underwriters who act without any firm
being designated as its or their representatives;

     (iii)  They have made a review in accordance with standards established by

consolidated statements of cash flows included in the Prospectus and/or included
in the Company's quarterly reports on Form 10-Q incorporated by reference into
the Prospectus as indicated in their reports thereon copies of which have been
separately furnished to the Representatives; and on the basis of specified
procedures including inquiries of officials of the Company who have
responsibility for financial and accounting matters regarding whether the
unaudited condensed consolidated financial statements referred to in paragraph
(vi)(A)(i) below comply as to form in all material respects with the applicable
accounting requirements of the Act and the Exchange Act and the related

do not comply as to form in all material respects with the applicable accounting
requirements of the Act and the Exchange Act and the related published rules and
regulations;

     (iv) The unaudited selected financial information with respect to the

its subsidiaries, inspection of the minute books of Weeks and its subsidiaries
since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus, inquiries of officials of the
Company, Weeks and their subsidiaries responsible for financial and accounting
matters and such other inquiries and procedures as may be specified in such
letter, nothing came to their attention that caused them to believe that:

(A)  (i) the unaudited condensed consolidated statements of income, consolidated
     balance sheets and consolidated statements of cash flows included in the
     Prospectus and/or included or incorporated by reference in the Company's
     Quarterly Reports on Form 10-Q incorporated by reference in the Prospectus

     sheets and consolidated statements of cash flows included in the Prospectus
     or included in the Company's Quarterly Reports on Form 10-Q incorporated by

     accepted accounting principles;

          (B) any other unaudited income statement data and balance sheet items
     included in the Prospectus do not agree with the corresponding items in the
     unaudited consolidated financial statements from which such data and items
     were derived, and any such unaudited data and items were not determined on
     a basis substantially consistent with the basis for the corresponding
     amounts in the audited consolidated financial statements included or
     incorporated by reference in the Company's Annual Report on Form 10-K for
     the most recent fiscal year or the Company's Registration Statement on Form
     10, as applicable;

          (C) the unaudited financial statements which were not included in the
     Prospectus but from which were derived the unaudited condensed financial
     statements referred to in Clause (A) and any unaudited income statement
<PAGE>
 
     data and balance sheet items included in the Prospectus and referred to in
     Clause (B) were not determined on a basis substantially consistent with the
     basis for the audited financial statements included or incorporated by
     reference in the Company's Annual Report on Form 10-K for the most recent
     fiscal year or the Company's Registration Statement on Form 10, as
     applicable;

          (D) any unaudited pro forma consolidated condensed financial
     statements included or incorporated by reference in the Prospectus do not
     comply as to form in all material respects with the applicable accounting
     requirements of the Act and the published rules and regulations thereunder
     or the pro forma adjustments have not been properly applied to the
     historical amounts in the compilation of those statements;

          (E) as of a specified date not more than five days prior to the date
     of such letter, there have been any changes in the consolidated partners'
     capital of the Company (other partnership interests issued pursuant to
     rights to acquire partnership interests which were outstanding on the date
     of the latest balance sheet included or incorporated by reference in the
     Prospectus) or any increase in the consolidated long-term debt of the
     Company and Weeks and their subsidiaries, or any decreases in consolidated
     net current assets or partners' equity or other items specified by the
     Representatives, or any increases in any items specified by the
     Representatives, in each case as compared with amounts shown in the latest
     balance sheet included or incorporated by reference in the Prospectus,
     except in each case for changes, increases or decreases which the
     Prospectus discloses have occurred or may occur or which are described in
     such letter; and

          (F) for the period from the date of the latest financial statements
     included or incorporated by reference in the Prospectus to the specified
     date referred to in Clause (E) there were any decreases in consolidated net
     revenues or operating profit or the total or per unit amounts of
     consolidated net income or other items specified by the Representatives, or
     any increases in any items specified by the Representatives, in each case
     as compared with the comparable period of the preceding year and with any
     other period of corresponding length specified by the Representatives,
     except in each case for increases or decreases which the Prospectus
     discloses have occurred or may occur or which are described in such letter;
     and

     (vii)  In addition to the audit referred to in their report(s) included or
incorporated by reference in the Prospectus and the limited procedures,
inspection of minute books, inquiries and other procedures referred to in
paragraphs (iii) and (vi) above, they have carried out certain specified
procedures, not constituting an audit in accordance with generally accepted
auditing standards, with respect to certain amounts, percentages and financial
information specified by the Representatives which are derived from the general
accounting records of the Company, Weeks and their subsidiaries, which appear in
the Prospectus (excluding documents incorporated by reference), or in Part II
of, or in exhibits and schedules to, the Registration Statement specified by the
Representatives or in documents incorporated by reference in the Prospectus
specified by the Representatives, and have compared certain of such amounts,
<PAGE>
 
percentages and financial information with the accounting records of the
Company, Weeks and their subsidiaries and have found them to be in agreement.

          Amount of 6-7/8% Notes due March 15, 2005
          -----------------------------------------


Ladies and Gentlemen:

     We have acted as counsel for Weeks Realty, L.P., a Georgia limited
partnership (the "Operating Partnership"), in connection with the registration
under the Securities Act of 1933, as amended, of $100,000,000 aggregate
principal amount of 6-7/8% Notes due March 15, 2005 (the "Notes"), pursuant to a
Prospectus Supplement dated March 17, 1998 (the "Prospectus Supplement").

     In connection with this opinion, we have examined and relied upon such
records, documents, certificates and other instruments as in our judgment are
necessary or appropriate to form the basis for the opinions hereinafter set
forth.  In all such examinations, we have assumed the genuineness of signatures
on original documents and the conformity to such original documents of all
copies submitted to us as certified, conformed or photographic copies, and as to
certificates of public officials, we have assumed the same to have been properly
given and to be accurate.  As to matters of fact material to this opinion, we
have relied upon statements and representations of representatives of the
Company and of public officials.

     We have assumed that the execution and delivery of, and the performance of
all obligations under, an indenture (the "Indenture") dated as of March 20, 1998
between the Operating Partnership and State Street Bank and Trust Company, as
trustee (the "Trustee"), will be duly authorized by all requisite action by the
Trustee, and that the Indenture will be duly executed and delivered by, and will
be a valid and binding agreement of, the Trustee, enforceable against the
Trustee in accordance with its terms.

     2.  Upon the issuance and sale thereof as described in the Prospectus
Supplement and, when executed by the Operating Partnership and duly
authenticated by the Trustee in accordance with the terms of the Indenture, the
Notes will be (x) validly issued, (y) valid and binding obligations of the
Operating Partnership, enforceable against the Operating Partnership in
accordance with their terms, subject to bankruptcy, insolvency, reorganization,
moratorium and other similar laws relating to or affecting the enforcement of
creditors' rights generally, and general equitable principles (regardless of
whether enforcement is considered in a proceeding in equity or law), and (z)
entitled to the benefits of the Indenture.

     This opinion is given as of the date hereof, and we assume no obligation to
advise you after the date hereof of facts or circumstances that come to our
attention or changes in law that occur which could affect the opinions contained

          3.10  CONDITION AND SUFFICIENCY OF ASSETS.  Exhibit 3.10 attached 
                -----------------------------------                            
hereto contains a complete and accurate list of the buildings, structures,
fixtures and equipment of the Company and the Subsidiaries. To the Knowledge of
Codina the buildings, structures, fixtures and equipment of the Company and the

and are adequate for the uses to which they are being put and none of such
buildings, plants, structures, fixtures or equipment is in need of maintenance
or repairs except for ordinary, routine maintenance and repairs that are not

                                      -17-

material in nature or cost. The buildings, structures, fixtures and equipment of
the Company and the Subsidiaries are sufficient for the continued conduct of the
Company and the Subsidiaries businesses after the Closing in substantially the
same manner as conducted prior to the Closing.

           3.11  ACCOUNTS RECEIVABLE.  To the Knowledge of Codina all accounts
                 -------------------                                          
receivable of the Company and the Subsidiaries that are reflected on the Closing
Date Balance Sheet (collectively, the "Accounts Receivable") represent or will
represent valid obligations arising from sales actually made or services
actually performed in the Ordinary Course of Business.  To the Knowledge of
Codina the Accounts Receivable are current and collectible net of the respective
reserves shown on the Closing Date Balance Sheet or on the accounting records of
the Company and the Subsidiaries as of the Closing Date (which reserves are
adequate and calculated consistent with past practice and, in the case of the
reserve as of the Closing Date, will not represent a material adverse change in
the composition of such Accounts Receivable in terms of aging).  To the
Knowledge of Codina, subject to such reserves, each of the Accounts Receivable
either has been or will be collected in full in the Ordinary Course of Business.
To the Knowledge of Codina there is no pending contest, claim or right of set-
off, under any Contract with any obligor of an Accounts Receivable relating to
the amount or validity of such Accounts Receivable.  Exhibit 3.11 attached

to the Knowledge of Codina neither the Company nor any Subsidiaries has any
liabilities (whether absolute, accrued, contingent or otherwise) except for
liabilities or obligations reflected or reserved against in the Closing Date
Balance Sheet. The Company has provided Buyers with all information and detail
relating to any liability or obligation reflected on or reserved against in the
Closing Date Balance Sheet. Further, to the Knowledge of Codina, neither the
Company nor any Subsidiary is in material violation of or default under any
Contract which could give rise to any material liability or obligation not
disclosed on the Closing Date Balance Sheet.

           3.13  TAXES.  The Company and each Subsidiary has filed or cause to
                 -----

required to be filed by it and each Subsidiary either separately or as a member
of a group of corporations, pursuant to applicable Legal Requirements.  Sellers
have delivered to Buyers copies of all such Tax Returns filed since December 31,
1995.  The Company has paid on a timely basis or made provision for the payment
of all Taxes that have or may have become due pursuant to those Tax Returns or
otherwise, or pursuant to any assessment received by the Company or any
Subsidiary.  The charges, accruals and reserves with respect to Taxes on the
books of the Company and of the Subsidiaries are adequate (determined in
accordance with GAAP) and are at least equal to the Company's and the
Subsidiaries' liability for Taxes.  There exists no proposed tax assessment or

                                      -18-

other dispute or claim for Taxes against the Company or any Subsidiary except as
disclosed in the Closing Date Balance Sheet.  No consent to the application of
Section 341(f)(2) of the IRC has been filed with respect to any property or
assets held, acquired, or to be acquired by the Company.  All Taxes that the
Company and each Subsidiary is or was required by Legal Requirements to withhold
or collect have been duly withheld or collected and, to the extent required,
have been paid to the proper Governmental Body or other Person on a timely
basis.  All Tax Returns filed by the Company and each Subsidiary are true,
correct and complete.  Except with respect to the Subsidiaries, there is no tax
sharing agreement that will require any payment by the Company after the date of
this Agreement.  Neither the Company nor any Subsidiary has executed an
extension or waiver of any statute of limitations on the assessment or
collection of any Tax.  There is no audit, examination, deficiency or refund
Proceeding with respect to Taxes of any kind pending or Threatened, and there is
no basis in fact for any assessment of any additional Tax.  All documentary
stamp Taxes with respect to the issuance of all capital stock of the Company and
the Subsidiaries have been paid.

          3.14  NO MATERIAL ADVERSE CHANGE.  To the Knowledge of Codina, since

Indemnification Claim may materially and adversely affect the Indemnified Party
other than as a result of money damages or other money payments or (ii) the
Indemnified Party or parties may have legal defenses available to it which are
different from or additional to the defenses available to the Indemnifying
Party, the Indemnified Party shall have the right, at the Indemnifying Party's
expense, to jointly control the defense, compromise or settlement of such
Indemnification Claim.  In all events an Indemnified Party shall have the right
to participate in its defense at its own expense.  Notwithstanding the
foregoing, no Indemnifying Party shall be liable for any compromise or
settlement of any action or proceeding effected without its written consent
(which shall not be unreasonably withheld).  The Indemnifying Party shall not,
without the written consent of the Indemnified Party, settle or compromise any
Indemnification Claim or consent to the entry of any judgment with respect to
the Indemnified Party which does not include as an unconditional term thereof
the giving by the claimant or the plaintiff to the Indemnified Party a release
from all liability in respect of such Indemnification Claim.


          5.6  INDEMNITY LIMITS.
               ---------------- 

          (a) Indemnification Claims shall be reduced by proceeds actually
received by an Indemnified Party under insurance policies, risk sharing pools,
or similar arrangements specifically as a result of, and in compensation for,
the subject matter of an Indemnification Claim by such Indemnified Party.

to this Agreement unless and until all amounts for which Codina would otherwise
be obligated to indemnify Weeks under this Agreement exceeds $250,000; provided,
however, that if Codina's obligation under this Article V exceeds such limit,

obligated to indemnify St. Joe against any Indemnification Claim pursuant to

dollar up to the maximum amount of his liability; and (iii) in no event shall
the aggregate liability of Codina pursuant to this Agreement exceed $1,500,000
with respect to Weeks or $1,500,000 with respect to St. Joe.

          (c) Notwithstanding anything herein to the contrary, neither Weeks nor
St. Joe shall be obligated to indemnify against any Indemnification Claim
pursuant to this Agreement until such time as Codina's aggregate right to such
indemnification exceeds $250,000 with respect to indemnification by St. Joe;
provided, however that if St. Joe's obligation under this Article V exceeds such
limit, its obligation shall be for the full amount of such obligation, from the
first dollar up to the maximum amount of its liability; and $250,000 with
respect to indemnification by Weeks; provided, however, that if Weeks'
obligation under this Article V exceed such limit, its obligation shall be for

amount of its liability.  St. Joe's and Weeks' aggregate liability for
indemnification pursuant to Section 7.3 will not exceed $1,500,000 each.

               --------------------                                     
publicity with respect to this Agreement or the Contemplated Transaction will be
issued, if at all, at such time and in such manner as Buyers and Codina mutually
determine.  Unless consented to by Buyers and Codina in advance or required by

confidential and may not make any disclosure of this Agreement to any Person.

          6.3  CONFIDENTIALITY.  Each party hereto will maintain in confidence
               ---------------                                                
and will cause their respective directors, officers, employees, agents,
consultants and advisors to maintain in confidence, any written, oral or other
information obtained in confidence from another party hereto or the Company in
connection with this Agreement or the Contemplated Transactions, unless (i) such
information is already known to such party or to others not bound by a duty of
confidentiality or such information becomes publicly available through no fault
of such party, (ii) the use of such information is necessary or appropriate in
making any filing or obtaining any consent or approval required for the
consummation of the Contemplated Transactions, or (iii) the furnishing or use of
such information is required by legal proceedings; provided, however, that in
the event of disclosure pursuant to (ii) or (iii) hereof, such disclosing party
shall agree to provide prompt written notice to the other parties hereto prior
to disclosure and to disclose only that portion of the confidential information
which is legally required or otherwise necessary.

          6.4  ENFORCEMENT COSTS.  If any civil action, arbitration or other
               -----------------                                            
legal proceeding is brought for the enforcement of this Agreement, or because of
an alleged dispute, breach, default or misrepresentation in connection with any
provision of this Agreement, the successful or prevailing party or parties shall
be entitled to recover reasonable attorneys' fees, sales and use taxes, court
costs and all expenses even if not taxable as court costs (including, without
limitation, all such fees, taxes, costs and expenses incident to arbitration,
appellate, bankruptcy and post-judgment proceedings), incurred in that civil

other parties hereto will be irreparably damaged (and damages at law would be an
inadequate remedy) if this Agreement is not specifically enforced.  Therefore,
in the event of a breach or threatened breach by any party of any provision of
this Agreement, the other parties hereto shall be entitled, in addition to any
other rights or remedies or law or in equity to which such party may be
entitled, to an injunction restraining such breach, without being required to

     is defined in item 1 of Schedule 5.2(b) or (B) projects which are required
     to be developed by the CNL Partnership (as such term is defined in item of
     2 of Schedule 5.2(b)).  With respect to any activity described in clauses
     (A) and (B) of the preceding sentence, St. Joe covenants to use its
     reasonable best efforts to cause the Corporation's construction, leasing,
     development, consulting and management services to be utilized to the
     extent reasonably possible and not inconsistent with the contractual
     relationships described on Schedule 5.2(b).  All such services shall be
     rendered by the Corporation at prevailing market rates, from time to time.

(b)  Each of St. Joe and Weeks covenant and agree that in the event that it or
     its Affiliates desires to contract with the Corporation for the provision
     of services outside of South Florida, (i) such contract shall be at market
     rates and (ii) if the service desired is development service, and if the
     development activity to which the provision of such service relates is
     deemed competitive, e.g. such development projects could reasonably be
     deemed to compete for tenants, with the other party's (i.e., Weeks or St.
     Joe, as the case may be) existing or planned future activity as determined
     in such other party's sole discretion, it shall not contract with the
     Corporation without obtaining the prior written consent of the other party.

     or a Codina Weeks Partnership;  provided however, that the foregoing shall
                                     ----------------                          
     not apply to Codina's ownership of less than a 10% interest in a publicly
     traded company engaged in the real estate business provided that such
     ownership interest is passive in nature; and provided, further, that the
                                                  --------  -------          
     one and three year periods, as applicable, provided for above shall not
     apply if Codina's employment has been terminated by the Corporation other
     than for Corporation Cause or by Codina for Codina Cause.

(b)  If Weeks acquires Codina's Shares within four years from the date hereof,
     the restrictions set forth in Section 5.7(a)(i), if applicable, shall apply
     for the period Codina is a Shareholder of Codina Group or a member of Weeks

     the terms of this Agreement.

     Section 6.1(a), Codina may engage or invest in any other non-real estate
     business or investment activity.

St. Joe and Weeks with written notice containing the terms and conditions upon
which each of them shall have a right to participate (on an equal basis with
each other) in the development and ownership of the Brickell Avenue Office
Building Project, including all information concerning the project which is

participate in such project upon notifying Codina of its intent to participate
within 30 days of Codina providing written notice as herein provided.  In the
event that either St. Joe or Weeks does not elect to participate on the offered
terms within such 30 days period, the other party may participate with Codina in
such project.   In the event that neither St. Joe nor Weeks elects to
participate on the offered terms within the 30-day period, Codina shall be
entitled to develop and own the project without the participation of either of
St. Joe or Weeks.  In the event that any third party participates with him in
the development and/or ownership of such project, such third party may not
participate on terms and conditions more favorable than those offered to St. Joe

real estate development, leasing, management, construction, consulting or any
other real estate services in South Florida, and (ii) any Shareholder or its
Affiliates ceases to own a particular parcel of real property in South Florida,
such Shareholder or its Affiliate shall no longer be required to utilize the
Corporation for its real estate development, leasing, management, construction,
consulting or any other real estate services with respect to such property.

  5.10  Notice to Directors of Shareholder's Real Estate Activities.  Each of
        -----------------------------------------------------------          
the Shareholders covenants and agrees, to the extent not prohibited by an
applicable legal or other required confidentiality restrictions (which
restrictions each Shareholder will attempt to minimize in good faith) to timely
advise the Board of its planned real estate activities in South Florida for
which such Shareholder is obligated to utilize the Corporation's services to
assist the Corporation in allocating its resources and developing its business
plans.

Affiliates, Weeks, its Affiliates and the Corporation may solicit for employment
any of the employees of the others for a period of three years after the Closing
of the sale of Shares pursuant to the exercise of such put or call option;
provided however, (a) the party exercising the Put Option may employ the
- ----------------                                                        
personnel of the division transferred to it as the result of such exercise and
the employees of such division shall be deemed to be its employees for purposes
of this Section and (b) any selling party may negotiate with and employ Ford
Gibson.  In the event that a division is transferred to a Shareholder pursuant
to the exercise of a Put Option, each other party hereto agrees not to solicit
for employment any of the employees of such division for a period of two years
after the Closing of such Put Option.

  5.12  St. Joe Covenant.  St. Joe hereby covenants and agrees to use its
        ----------------                                                 
reasonable best efforts to cause FECI and the Gran Entity to comply with the
provisions of this Section 5 as if it were an Affiliate of St. Joe for purposes
of this Agreement.

acknowledges that Codina has entered into certain agreements more particularly
described on Schedule 5.13 (true and correct copies of which have been delivered
to Weeks and St. Joe) which will be violated if the Corporation engages in
certain activities.  Each of Codina, St. Joe and Weeks agree to cause the
Corporation not to engage in any activity which would cause Codina to violate
such obligations until (i) Codina consents in writing, (ii) the Corporation
obtains an unqualified legal opinion from counsel satisfactory to Codina that a
restriction has lapsed or that a particular activity will not violate such
restriction, or (iii) such restriction has expired by its express terms.

              ------ 

6.1 Devotion of Time; Compensation; Incentive Compensation;
    -------------------------------------------------------
    Modification of Compensation.
    ---------------------------- 


(a)  Devotion of Time.  Codina covenants and agrees that during the period of
     ----------------                                                        
     time he is a Shareholder, he will devote such reasonable time as is
     necessary for the operation of the Corporation consistent with his duties
     as the President and Chief Executive Officer of the Corporation and his
     past practices;  provided however, each of St. Joe and Weeks acknowledge
                      ----------------                                       
     and agree that Codina shall not be required to devote his full time to the
     Corporation and that he will be permitted to continue (i) his involvement
     in existing and future civic activities, non-real estate related business
     activities and the real estate activities provided in Section 5.7 outside
     of the Corporation and/or a Codina Weeks Partnership and (ii) to serve as a
     member of the boards of directors of the corporations on which he currently
     serves and on additional boards of directors from time to time, in each
     case for as long as such activities do not unreasonably interfere with the
     operations of the Corporation.

(b)  The Board shall elect Codina as the President and Chief Executive Officer
     of the Corporation.  Codina shall serve in such capacities until the
     Corporation or Codina terminates such relationship upon 60 days prior
     written notice unless he is terminated for Corporation Cause.

(c)  Base Compensation.  During the period of time that Codina is employed by
     -----------------                                                       
     the Corporation, Codina shall receive an annual base salary in an amount
     equal to $250,000.00, increased each year by the Consumer Price Index
     increase, if any from the immediately preceding year.  The base salary will
     be paid in periodic payments consistent with the Corporation's payroll
     practices from time to time.  Codina shall be reimbursed for all reasonable
     expenses incurred by him in the performance of his duties to the
     Corporation and accounted for in accordance with the Corporation's expense
     guidelines and reimbursement procedures and practices in effect from time
     to time, including, without limitation, travel, hotel and entertainment.

(d)  Incentive Compensation.  During any calendar year during the term of his
     ----------------------                                                  
     employment by the Corporation, the Corporation shall pay, and Codina shall
     receive, incentive compensation for each year (or a pro rata portion
     thereof if Codina's employment by the Corporation is terminated prior to
     the end of a calendar year for any reason other than (A) Corporation Cause
     or (B) his resignation for other than Codina Cause) equal to the sum of (i)
     10 percent of the amount, if any, by which the EBITDA for such year exceeds
     an amount equal to 110 percent of the greater of (x) the EBITDA for the

                                       21
<PAGE>
 
     immediately preceding year or (y) $4,200,000.00/1/, (ii) 3 percent of the
     amount, if any, by which the EBITDA for such year exceeds the greater of
     (x) an amount equal to 115 percent of EBITDA for the immediately preceding
     year and (y) $4,200,000.00, and (iii) 5 percent of the amount, if any, by
     which the EBITDA for such year exceeds the greater of (x) an amount equal
     to 125 percent of EBITDA for the immediately preceding year and (y)
     $4,200,000.00.  If Codina's employment by the Corporation is terminated
     prior to the end of a calendar year for any reason other than (A)
     Corporation Cause or (B) his resignation for other than Codina Cause,
     Codina's incentive compensation, if any, shall be computed on a partial
     year basis calculated on the Corporation's EBITDA through the date of
     termination and adjusting the $4,200,000 and the prior year's EBITDA
     thresholds based on the portion of the year elapsed.  For purposes of this
     Section 6.1(d), EBITDA shall be calculated prior to any reduction for
     incentive compensation payable to Codina.

(e)  Modification of Base Compensation or Incentive Compensation.  Neither the
     -----------------------------------------------------------              
     amount of base salary to which Codina is entitled pursuant to Section
     6.1(c) hereof nor the formula for computing the amount of incentive
     compensation to which Codina is entitled pursuant to Section 6.1(d) hereof
     may be reduced or otherwise changed without the approval of Codina;
     provided however, the formula for the computation of the amount of
     ----------------                                                  
     incentive compensation to which Codina is entitled may be changed by the
     Compensation Committee of the Board if such change does not materially
     reduce the amount of incentive compensation to which Codina would have been
     entitled to prior to such change when both the old and new formulae are
     applied to the actual financial results.

(f)  Benefits.  Codina shall be entitled to participate in such medical, dental,
     --------                                                                   
     disability, hospitalization, life insurance, profit sharing and other
     benefit plans which are maintained for the benefit of executive officers of
     the Corporation on the terms and subject to the conditions set forth in
     such plans.

6.2  Non-exclusive License.  Codina and the Corporation shall enter into the
     ---------------------

       ----------------- 

  The Corporation will adopt the Stock Option Plan.  The exercise price of the

  8.1  Put Option.
       ---------- 

(a)  At any time commencing three years after the date of this Agreement, either
     St. Joe or Weeks, but not both (the first of such Shareholders to initiate
     the provisions of this Section 8.1(a), the "Selling Shareholder"; and the
     other of such Shareholders, the "Purchasing Shareholder"), shall have the
     right (such right, the "Put Option"), upon providing 45 days prior written
     notice to the Corporation and other Shareholders, to require, subject to
     Sections 8.2 and 8.3 hereof, the Purchasing Shareholder to purchase all of
     its Shares for an amount equal to the Purchase Price payable as provided in
     Section 8.1(b) and otherwise as provided in this Section 8.

(b)  In the event the Selling Shareholder exercises its Put Option, the Purchase
     Price shall be paid to the Selling Shareholder by the Purchasing
     Shareholder causing the Corporation to distribute, in the event that St.
     Joe is the Selling Shareholder, the St. Joe Division and, in the event that
     Weeks is the Selling Shareholder, the Weeks Division (such distributed
     division, the "Distributed Division"), to the Selling Shareholder.  In the
     event that the Purchase Price exceeds the Distributed Division Value, the
     Purchasing Shareholder shall pay in cash to the Selling Shareholder at the
     Closing an amount equal to the amount by which the Purchase Price exceeds
     the Distributed Division Value.   In the event that the Distributed
     Division Value exceeds the Purchase Price, the Selling Shareholder shall
     pay in cash at the Closing to the Purchasing Shareholder, an amount equal
     to the amount by which Distributed Division Value exceeds the Purchase
     Price.  The Purchasing Shareholder shall pay in cash at the Closing to the
     Corporation an amount equal to the Distributed Division Value of the
     division distributed to the Selling Shareholder.  All Shareholders covenant
     and agree that they will take and will cause to be taken at all times all
     necessary action, including without limitation, the voting of Shares to
     distribute a division to effectuate the provisions of this Section 8.1(b).

     Option within 60 days after the third anniversary of this Agreement, both
     such exercises of the Put Option shall be void ab initio and neither Weeks
                                                    ---------                  
     nor St. Joe may exercise the Put Option (i) for a period of 30 days after
     the last of the foregoing exercises or (ii) if either  Weeks or St. Joe
     initiates the buy-sell procedure set forth in Section 8.10, at any time
     thereafter.

  8.2  Codina Option to Purchase One-half of Selling Shareholder's Shares.  If
       ------------------------------------------------------------------     
either St. Joe or Weeks exercises its Put Option pursuant to Section 8.1 and
such exercise is not voided as provided in Section 8.1(c), Codina shall have the

<PAGE>
 
right, in his sole discretion and upon providing written notice within 15 days
of receipt of the Selling Shareholder's notice of its exercise of the Put Option
to the Corporation and the other Shareholders, to purchase one-half, but not
less than one-half, of the Selling Shareholder's Shares.  If Codina elects to
purchase one-half of the Selling Shareholder's Shares, Codina shall become a
Purchasing Shareholder with respect to one-half of the Selling Shareholder's
Shares and shall have all the rights and obligations of a Purchasing Shareholder
of such Shares as provided in this Section 8.  The original Purchasing
Shareholder shall continue as a Purchasing Shareholder of one-half of the
Selling Shareholder's Shares and shall have all the rights and obligations as
such are provided in this Section 8.

  8.3  Purchasing Shareholder's Option.
       ------------------------------- 

(a)  Notwithstanding anything contained herein to the contrary, if either St.
     Joe or Weeks is obligated to purchase Shares pursuant to Section 8.1, the
     Purchasing Shareholder shall have the right, in its sole discretion, to
     either (i) if Codina so desires, in his sole discretion, allow Codina to
     acquire the Shares required to be purchased by it pursuant to Section 8.1,
     or (ii) upon obtaining Codina's prior written consent, which consent may be
     withheld in his sole discretion, allow another Person to acquire the Shares
     required to be purchased by it pursuant to Section 8.1 (such other Person,
     the "Designated Purchaser").

(b)  If Codina purchases all of the Selling Shareholder's Shares pursuant to
     clause (i) of Section 8.3(a), Codina shall become the Purchasing
     Shareholder and shall have all of the rights and obligations as such are
     provided in this Section 8.

(c)  If a Designated Purchaser purchases all of the Selling Shareholder's Shares
     pursuant to clause (ii) of Section 8.3(a), the Designated Purchaser shall
     become the Purchasing Shareholder and shall have all of the rights and
     obligations as such are provided in this Section 8.

actual knowledge of a Change in Control of Weeks, St. Joe shall have the right
(the "St. Joe Call Option") to require, upon providing 45 days prior written

shorten the 180-day exercise period) to the Corporation and the other
Shareholders, Weeks to sell its Shares to St. Joe for an amount equal to the
Purchase Price payable as provided in Section 8.1(b), as if St. Joe is the
Purchasing Shareholder and Weeks is the Selling Shareholder.

after, and prior to twenty-four months after, the date hereof, if (A) St. Joe
and a Codina Weeks Partnership have not reached agreement after good faith
negotiations upon the timing and terms of the formation of the partnership which
will develop the Airport Land, or (B) FECI and the Gran Entity have not agreed
in writing to be bound by the terms of this Agreement as if they were Affiliates
of St. Joe for purposes of this Agreement, or (iii) within 180 days after Weeks
has actual knowledge that FECI has engaged in any activity that would be
prohibited under Section 5 of this Agreement if it were deemed to be an
Affiliate of St. Joe for purposes of this Agreement, Weeks shall have the right
(the "Weeks Call Option") to require, upon providing 45 days prior written

                                       24

shorten the 180-day exercise period) to the Corporation and the other
Shareholders, St. Joe to sell its Shares to Weeks for an amount equal to the

Purchasing Shareholder and St. Joe is the Selling Shareholder.

  8.6  Codina Put Option.
       -----------------

     Option"), at any time after the Put Time (except if the Put Time occurs as
     a result of Codina's death, within 180 days after the date of Codina's
     death), to require, upon providing 45 days prior written notice to the
     Corporation and the other Shareholders, the then current Shareholders which
     are members of the Weeks Control Group or St. Joe Control Group to acquire,
     in proportion to their relative ownership interests in the Corporation
     without considering Codina's Shares and Option Shares, all of Codina's
     Shares.  At the Closing, each of the then Shareholders which are members of
     the Weeks Control Group or St. Joe Control Group shall pay to the holders
     of Codina's Shares in cash or, at the election of the holders of the Codina
     Shares, in stock or units of limited partnership interest as provided in
     Section 8.6(b), an amount equal to the product of  (a) the Purchase Price
     and (b) a fraction, the numerator of which is the number of Shares owned by
     such Shareholder and the denominator of which is the total number of Shares
     owned by members of the Weeks Control Group and St. Joe Control Group.

(b)  If either Weeks or St. Joe is the sole other Shareholder at the time of the
     exercise of the Codina Put Option, at the election of the holders of the
     Codina Shares, Weeks or St. Joe, as the case may be, shall use its
     reasonable best efforts to structure the acquisition of Codina's Shares on
     a tax efficient basis to the holders of the Codina Shares, through either a
     merger or, if Weeks is the only Shareholder, the contribution by the
     holders of the Codina Shares to Weeks Realty, L.P. in exchange for common
     units of limited partnership interests therein.  If Weeks and St. Joe are
     both Shareholders at the time of the exercise of the Codina Put Option, at
     the election of the holders of the Codina Shares, Weeks shall use its
     reasonable best efforts to structure its portion of the acquisition on a
     tax efficient basis to the holders of the Codina Shares through a
     contribution by the holders of the Codina Shares to Weeks Realty, L.P. in
     exchange for common units of limited partnership interest therein.  No
     holder of Codina Shares shall be entitled to elect to receive securities of
     Weeks Corp. or Weeks Realty, L.P unless at the time of such election such
     holder is an "accredited investor" as defined under Rule 501(a) of the
     Securities Act of 1933, as amended.

  8.7  Default Call.  In the event that as a result of a merger, consolidation
       ------------                                                           
or other business combination by either St. Joe or Weeks, St. Joe or Weeks is in
default of Section 5.1, 5.2 or 5.3.  Weeks or St. Joe as the nondefaulting
party, as the exclusive remedy for such default, shall have the right (such
right, the "Default Call"), at any time within 180 days after such breach, upon
providing 45 days prior written notice (provided that such 45-day prior notice
requirement shall not operate to shorten the 180-day exercise period) to the
Corporation and the other Shareholders, to acquire the defaulting party's Shares
for an amount equal to the Purchase Price payable as provided in Section 8.1(b)
hereof, as if the defaulting Shareholder is the Selling Shareholder and the
nondefaulting Shareholder is the Purchasing Shareholder.

     the 70-day period or (B) the giving of written notice by the Corporation to
     Codina and each Offered Shareholder that it will not exercise the
     Corporation Call Option, to elect to purchase their pro rata share of

     elected to purchase their pro rata share of the Codina Shares shall have

     Price.

shorten the 180-day exercise period) to Codina, Codina to sell his Shares to
Weeks, for an amount equal to the Purchase Price.

(b)  At any time (i) within 180 days after the first anniversary of Weeks
     acquisition of St. Joe's Shares or (ii) within 180 days after the

(a)  If both Weeks and St. Joe exercise the Put Option within 60 days after the
     third anniversary of this Agreement, at any time within the 30 day period
     following the date of the last of such exercises, either Weeks or St. Joe

(a)  Closing.  Except as otherwise agreed to by all of the purchasing and
     -------                                                             
     selling Shareholders, all sales of a Shareholder's Shares pursuant to the
     provisions of Section 8 shall take place at the Closing on the Closing Date
     and shall occur in accordance with the following Sections 8.11(b) through
     (f).

(b)  Closing Date.  The closing date ("Closing Date") shall be as applicable (i)
     ------------                                                               
     the date 60 days after the providing of written notice by the Shareholder
     which initiated the sale of such Shares pursuant to Section 8 or such
     earlier date as the buying and selling Shareholders so determine or (ii) 30
     days following the date of the exercise of an option or the expiration of
     the time period provided for in Section 8.10(c); provided, however, if, in
     connection with any such closing, a Notification and Report Form is
     required to be filed under the Hart-Scott-Rodino Antitrust Improvements Act

                                       27
<PAGE>
 
     of 1976, the Closing Date shall be deferred until the expiration or early
     termination of the notice periods required under such Act.

(c)  Place and Time.  The Closing shall be held at 1:00 p.m. on the Closing
     --------------                                                        
     Date, at the offices of the Corporation, or at any other time and place as
     the parties shall agree.

(d)  Payment and Delivery.  At the Closing, the Purchase Price shall be paid in
     --------------------                                                      
     accordance with Sections 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9 or
     8.10, as the case may be, and the selling Shareholder shall deliver
     certificates representing all of the Shares to be sold, duly endorsed, free
     and clear of all liens and encumbrances.

(e)  Failure to Deliver Certificates. If the Shareholder required to sell Shares
     -------------------------------                                            
     pursuant hereto does not deliver the certificates at the Closing of a sale
     of Shares pursuant to Section 8 hereof, then the Corporation shall cause
     its transfer books to reflect that such Shares have been transferred to the
     purchasing Shareholder, as of the Closing Date.

(f)  Attorney-in-Fact.  Each Shareholder hereby appoints the Corporation,
     ----------------                                                    
     through its Secretary or such other officer as the Board may designate, as
     its attorney-in-fact to execute and deliver all documents needed to convey
     the Shares to the purchasing Shareholder, if the Shareholder does not
     deliver the Shares at the Closing as required hereby.  This power of
     attorney is coupled with an interest, does not terminate on the
     Shareholder's disability or death, and continues for so long as this
     Agreement is in effect.

  8.12  Fair and Sufficient Purchase Price.  With respect to any sale of Shares
        ----------------------------------                                     
pursuant to Section 8, the Shareholders acknowledge that the Purchase Price may
not, depending upon the circumstances, reflect the fair market value of such
Shares, but that in any event such price constitutes fair and sufficient
consideration for the Shares as determined through the process of arms-length
negotiations among the parties hereto.

  8.13  REIT Qualification.  In the event that an amendment to the Internal
        ------------------                                                 
Revenue Code of 1986, as amended (the "Code") subsequent to the date hereof
could, in the reasonable opinion of counsel to Weeks Corp., result in a material
risk that Weeks' compliance with the put/call provisions under this Section 8
would jeopardize Weeks Corp.'s qualification as a real estate investment trust
under Sections 856 through 860 of the Code, the parties shall negotiate in good
faith to modify such provisions in a manner that would, in the reasonable
opinion of counsel to Weeks Corp., eliminate such material risk of
disqualification and would preserve to the greatest extent practicable the
original agreement of the parties under the applicable provisions of this
Section 8; provided that no modification shall terminate the right of the
applicable selling Shareholder to sell its Shares or to require a Shareholder to
sell his or its Shares except as otherwise required under such Section on the
terms set forth therein.

  Section 9.  Transfer of Shares.
              ------------------ 

  9.1  Restrictions on Transfer. No Shareholder shall, directly or indirectly,
       ------------------------                                               
Transfer any Shares, and no Shares shall be, directly or indirectly,
Transferred, except for Permitted Transfers and Transfers in compliance with
Section 9.2.  Except for Permitted Transfers, and Transfers made in accordance
with Section 9.2, no Shareholder shall, at any time, (i) deposit any Shares
under a voting trust or similar agreement, or otherwise Transfer any shares to
any Person for the purpose of vesting in such Person the right to vote such
Shares; (ii) enter into any agreement providing for the voting of Shares as
directed by any Person, or in a specified manner, or pursuant to a specified
procedure; or (iii) grant any voting proxy or otherwise enter into any agreement
or arrangement, the purpose or effect of which is to vest in any other Person
the voting rights of the Shares from time to time held by such Person.  Any such
Transfer not made in compliance with this Section 9 shall be void ab initio and
                                                                  -- ------    
of no effect whatsoever.  The provisions of this Section 9.1 shall not be
applicable to sales of Shares in a Qualified Public Offering.

  9.2  Right of First Refusal.
       ---------------------- 

(a)  Except as otherwise provided hereinafter, if any Shareholder (the "Offering
     Shareholder") shall desire to sell all but not less than all of his or its
     Shares (the "Offered Shares"), the Corporation and the remaining
     Shareholders (the "Non-Offering Shareholders") shall have the right of
     first refusal to purchase the Offered Shares upon the terms and conditions
     hereinafter provided.  Prior to any Transfer of Offered Shares, the
     Offering Shareholder shall have received a written bona fide offer from a
     third party to purchase the Offered Shares stating the number of Shares to
     be purchased and the price and terms upon which such Shares are proposed to
     be Transferred, and shall have delivered a copy of such written bona fide
     offer to the Corporation and each of the Non-Offering Shareholders.  The
     Corporation shall have the right to elect within 30 days thereafter to
     purchase all, but not less than all, of the Offered Shares at the lesser of
     the Purchase Price or the same price and upon the same terms and conditions
     as those contained in such offer by giving notice to the Offering
     Shareholder within the 30-day period.  The Offering Shareholder shall not
     participate in any way in the making of the decision as to whether the
     Corporation shall accept or reject the offer.  Any attempted conditional or
     partial acceptance of the offer by the Corporation shall constitute a
     rejection.

(b)  If the Corporation does not accept an offer made in accordance with Section
     9.2(a) above within the 30-day period, then the Non-Offering Shareholders
     shall have the right, within 5 days following the earlier of either (i) the
     expiration of the 30-day period or (ii) the giving of written notice by the
     Corporation to the Offering Shareholder and each Non-Offering Shareholder
     that it will not purchase the Offered Shares, to elect to purchase their
     pro rata share of the Offered Shares at the lesser of the Purchase Price or
     the same price and upon the same terms and conditions as those contained in
     such offer by giving written notice to the Offering Shareholder and the
     Corporation within the five-day period.  Any attempted conditional or
     partial acceptance of the offer by a Non-Offering Shareholder shall
     constitute a rejection.

(c)  If any Non-Offering Shareholder does not elect to purchase his or its pro
     rata share of the Offered Shares (the "Remaining Offered Shares") within
     the 5-day period specified in Section 9.2(b) above, the Non-Offering
     Shareholders who have elected to purchase their pro rata share of the
     Offered Shares shall have the right, exercisable for a period of five days
     after the five-day period specified in Section 9.2(b) above, to purchase

                                       29
<PAGE>
 
     the Remaining Offered Shares pro rata or in such other proportion as they
     may agree.  The Non-Offering Shareholders must purchase in the aggregate
     all of the Offered Shares, or else they may not purchase any of the Offered
     Shares.

(d)  If the Corporation and the Non-Offering Shareholders do not elect to
     purchase all of the Offered Shares within the aforesaid periods, or, if
     after accepting such offer, the Corporation fails to purchase all of the
     Offered Shares in accordance herewith and (i) the Non-Offering Shareholders
     do not elect to purchase all of the Offered Shares within the periods
     provided herein or (ii) the Non-Offering Shareholders elect to accept such
     offer but fail to purchase all of the Offered Shares in accordance
     herewith, then, subject to the provisions of Section 9.4, the Offering
     Shareholder shall be free to Transfer all of the Offered Shares to the
     third party that submitted the written bona fide offer at not less than the
     price and on the same terms and conditions set forth in such bona fide
     offer within 90 days following, as the case may be, (a) the default by the
     Non-Offering Shareholders to make such purchase of the Offered Shares on
     the Closing Date, or (b) the earlier of either (A) the expiration of the
     period within which the Non-Offering Shareholders may elect to purchase the
     Offered Shares or (B) the giving of written notice by the Non-Offering
     Shareholders to the Offering Shareholder that they do not elect to purchase
     all of the Offered Shares; provided that in no event shall a Shareholder be
                                -------- ----                                   
     permitted to sell its Shares to a Person which is a competitor of the
     Corporation or any of its Shareholders, as reasonably determined by the
     disinterested members of the Board.  Promptly after the execution of any
     contract for the Transfer of the Offered Shares, the Offering Shareholder
     shall deliver to the Corporation a true and complete copy of such contract
     and all amendments thereto, and such other information relating to the
     contract and the proposed purchaser as the Corporation may request.  Upon
     the consummation of the Transfer of the Offered Shares, the Shareholder
     shall notify the Corporation thereof and shall certify the price and terms
     and conditions upon which such Transfer was made.

(e)  If the Offering Shareholder does not Transfer all of the Offered Shares
     within the 90-day period specified in Section 9.2(d) above, then the rights
     of the Corporation and the other Shareholders under this Section 9.2 shall
     be fully restored and reinstated as if such offer had never been made;
     provided, however, that the 90-day period shall be extended during any
     period in which such sale is not completed as a result of an act of God,
     war or other force majeure.

  9.3  Default by Corporation.  If the Corporation accepts an offer for Shares
       ----------------------                                                 
made in accordance with Section 9, and then, on the Closing Date, the
Corporation defaults (other than a willful default) or is precluded by law from
consummating such purchase at the price or on the terms and conditions
prescribed hereby, the Non-Offering Shareholders shall have the options set
forth in Sections 9.2(b) and 9.2(c), dating from such Closing Date.

  9.4  Validity and Effect of Transfer.
       ------------------------------- 

(a)  Notwithstanding anything in this Agreement to the contrary, no Transfer of
     Shares or rights shall be deemed to be a Permitted Transfer or a
     permissible transfer pursuant to Section 9.2 unless the Permitted
     Transferee or Section 9.2 transferee agrees in writing for the benefit of
     the other Shareholders, as a condition to such Transfer, to be bound by all
     of the provisions of this Agreement to the same extent as was the
     transferor hereunder; and provided, further, that the provisions hereof

                                       30
<PAGE>
 
     shall be self-operative such that any such Permitted Transferees or Section
     9.2 transferee shall take all such Shares and rights subject to all the
     provisions of this Agreement as if such Shares or rights were still held by
     the Shareholder who made the Transfer, whether or not they so agree with
     the Shareholder who makes the Transfer or with the other Shareholders.

(b)  If any Transfer is made or attempted contrary to the provisions of this
     Agreement, such purported Transfer shall be void ab initio; the other
                                                      -- ------           
     Shareholders shall have, in addition to any other legal or equitable
     remedies which they may have, the right to enforce the provisions of this
     Agreement by actions for specific performance (to the extent permitted by
     law).  Without limitation to the foregoing, each of the Shareholders
     further agrees that the provisions of Section 13.11 shall apply in the
     event of any violation or threatened violation of this Agreement.

(c)  If a Permitted Transferee is a member of its transferor's Control Group
     then the Permitted Transferee or such Control Group, if the Shares of such
     Control Group are held by more than one member of such Control Group, shall
     have, either individually or collectively, as the case may be, all of the
     rights and obligations of Control Group's initial Shareholder under this
     Agreement.  A transferee under Section 9.2 shall succeed to all of the
     rights of its transferor hereunder except if such transferee's transferor
     is Codina or a Permitted Transferee of Codina, the Codina Put Option.

  9.5  Acknowledgment of Restrictions.  Each of the Shareholders acknowledges
       ------------------------------                                        
and understands that the limitations imposed upon him or it by Sections 8 and 9
with respect to such Shareholder's ownership of Shares significantly limit such
Shareholder's ability to Transfer, and realize any value from, the Shares owned
by the Shareholder.

  Section 10.  Notations of Restrictions on Certificates.  All certificates
               -----------------------------------------                   
evidencing Shares shall bear legends on the face thereof substantially as
follows:

       The shares represented by this certificate have not been registered under
     the Securities Act of 1933, as amended (the "Act"). Such shares have been
     acquired for investment and may not be sold or transferred in the absence
     of an effective registration statement for such shares under the Act or an
     opinion of counsel for the Corporation that registration is not required
     under the Act.

       The shares evidenced by this certificate are subject to the restrictions
     and options stated in, and are transferable only upon compliance with, the
     provisions of the Shareholders' Agreement, dated as of February ___, 1998,
     by and among Codina Group, Inc., and its shareholders, as amended from time
     to time, a copy of which is on file in the office of the Secretary of the
     Corporation, the provisions of which are incorporated herein by reference.

  Section 11.  Termination of Agreement.  This Agreement shall terminate, and
               ------------------------                                      
the certificates representing the Shares subject to this Agreement shall be
released from the terms of this Agreement, upon the occurrence of any of the
following events:

  (a) cessation of the Corporation's business;

                                       31

 (b) written agreement of the Shareholders owning all of the Shares;

 (c) adjudication of bankruptcy or dissolution of the Corporation or appointment
     of a receiver for the Corporation or any substantial part of its assets;

 (d) acquisition by one Person of all of the outstanding Shares; or

 (e) the sale by the Corporation and/or its Shareholder of stock of the
     Corporation in a Qualified Public Offering.

  Section 12.  Arbitration.
               ----------- 

  12.1  Application of Section.  Whenever either (a) the Shareholders have a
        ----------------------                                              
dispute regarding the interpretation of this Agreement or (b) the Shareholders
mutually agree to submit any other question, matter or dispute to arbitration,
the provisions of this Section shall apply.

  12.2  Initiating Arbitration, Selection of Arbitrators.  Any Shareholder may
        ------------------------------------------------                      
submit any question, matter or dispute set forth in Section 12.1 to arbitration
at which time the submitting Shareholder shall provide written notice to each of
the other Shareholders of its intent to initiate the arbitration proceedings set
forth herein.  Within thirty (30) days after receipt of a request to arbitrate a
dispute, if there are three Shareholders, each Shareholder shall appoint one
arbitrator.  If any Shareholder shall fail to make such appointment within said
30-day period within 15 days after the expiration of the 30-day period, the
other Shareholders shall jointly appoint another arbitrator, or, in the event
that the other Shareholders can not agree upon the appointment of a third
arbitrator, the two appointed arbitrators shall select a third arbitrator within
said 15-day period.  If the other Shareholders and/or the two appointed
arbitrators are unable to agree within fifteen (15) days, then any Shareholder
may, upon at least five days' prior written notice to the other Shareholders,
request the Presiding Judge of the Circuit Court of the Eleventh Judicial
Circuit, in and for Miami-Dade County, Florida, ("Judge") acting in his or her
private and nonjudicial capacity, to choose an arbitrator to fill the vacancy.
The Judge may thereupon appoint an arbitrator to complete the panel of three
arbitrators.  If there are only two Shareholders, each Shareholder shall appoint
one arbitrator within thirty (30) days after a receipt of a request to arbitrate
a dispute.  If a Shareholder shall fail to make such appointment within said 30-
day period, the other Shareholder shall appoint the second arbitrator.  The two
appointed arbitrators shall select a third arbitrator.  If the two arbitrators
are unable to agree within fifteen (15) days, then any Shareholder may request
the Judge to choose an arbitrator to fill the vacancy.

  All arbitrators shall be impartial and unrelated, directly or indirectly, so
far as employment of services is concerned to any of the Shareholders or to any
Affiliate or to any person directly or indirectly related to any Affiliate or to
any person directly or indirectly related to the Shareholders.  In an
arbitration proceeding involving the management and operation of the
Corporation, the arbitrators shall have substantial knowledge and experience in
the management and operation of similar companies.  In any arbitration
proceedings involving any other specialized area of knowledge or competence, the
arbitrators shall have substantial knowledge and experience in such specialized
area as, for example, in any dispute involving accounting procedures the
arbitrators shall be independent certified public accountants. The arbitration
proceeding shall otherwise be governed by the rules of the American Arbitration

                                       32

Association then in force.

  12.3  Procedures: Limitations on Authority.  The three arbitrators shall
        ------------------------------------                              
investigate the facts and shall hold hearings at which the Shareholders may
present evidence and arguments, be represented by counsel and conduct cross
examination.  The three arbitrators shall render a written decision upon the
matter presented to them by a majority vote within ninety (90) days after the
date upon which the last arbitrator is appointed, and that decision shall be
final and binding on the Shareholders, subject to the provisions of Section 12.4
hereof.   Judgment upon the decision rendered in such arbitration may be entered
by any court having jurisdiction thereof.  No Shareholder shall be considered in
default hereunder during the pendency of arbitration proceedings relating to a
disputed default.  If the three arbitrators shall fail to render a decision
within said 90-day period, any Shareholder may initiate a second arbitration
proceeding as provided in Section 12.1 and if the second set of arbitrators
shall fail to render a decision within said 90-day period the Shareholder shall
have the right to institute such action or proceeding in such court as shall be
appropriate in the circumstances.  Upon the institution of such action, the
arbitration proceeding shall be terminated and shall be of no further force and
effect.  The arbitrators shall determine in what proportion the Shareholders
shall bear the fees and expenses of the arbitrator appointed by or on behalf of
it and each Shareholder shall bear the fees and expenses of its own counsel and
other consultants.  In determining any question, matter or dispute before them,
the arbitrators shall apply the provisions of this Agreement, without varying
therefrom in any respect. They shall not have the power to add to, modify or
change any of the provisions of this Agreement.

  12.4  Review of Arbitration Decision.  Notwithstanding anything contained
        ------------------------------                                     
herein to the contrary, any Shareholder may seek review of any arbitration
decision made pursuant to this Section 12 by a court of competent jurisdiction
whose review shall be limited to a determination that there is substantial
competent evidence to support the facts as found by the arbitrators and that the
arbitrators have applied the law applicable to the dispute.  The decision of the
trial court may be appealed to an appellate court.

  Section 13.  Miscellaneous.
               ------------- 

  13.1  Amendment.  This Agreement may be amended only by a writing signed by

understandings and agreements heretofore or simultaneously had among the parties

                                       35

application of a provision to any person or circumstance, shall be held invalid,

of such provision to persons or circumstances other than those to which it is
held invalid, shall not be affected.

  13.10  Phrase Reference.  Wherever from the context it appears appropriate,

to perform any of the obligations set forth in this Agreement.  Therefore, if
any party shall institute any action or proceeding to enforce the terms or
alleging a breach of the provisions of this Agreement, in addition to any other
remedy available at law, such party may seek specific performance of the terms

hereby waives the claim or defense that a remedy at law alone is adequate, and
agrees (to the maximum extent permitted by law) to have such provision
specifically enforced against it by any court of equity, without the necessity
of posting bond or other security against it, and consents to the entry of

threatened violation of this Agreement.

to the jurisdiction of the United States District Court for the Southern
District of Florida for the purpose of any suit, action or other proceeding

hereby waive, and agree not to assert, by way of motion, as a defense, or
otherwise, in any such suit, action or proceeding, any claim that they are not
subject personally to the jurisdiction of the above-named courts, that the suit,
action or proceeding is brought in an inconvenient forum, that the venue of the
suit, action or proceeding is improper or that this Agreement or the subject
matter hereof may not be enforced in or by such court.  The parties hereto
hereby consent to service of process by registered mail at the address to which
notices are to be given.  The parties hereto agree that their submission to
jurisdiction and their consent to service of process by mail is made for the
express benefit of the other parties hereto.  Final judgment against any party
hereto in any such action, suit or proceeding shall be conclusive and may be
enforced in other jurisdictions (A) by suit, action or proceeding on the
judgment, a certified or true copy of which shall be conclusive evidence of the
fact and of the amount of any indebtedness or liability of the party therein
described or (B) in any other manner provided by or pursuant to the laws of such

Agreement by any party hereto shall not be construed as a waiver of a subsequent
breach of the same or any other provision, nor shall any delay or omission by a
nondefaulting party to seek a remedy for any breach of this Agreement or to

WEEKS CORPORATION (WKS) COMPLETES $100 MILLION SEVEN-YEAR NOTE OFFERING

Atlanta, Georgia (March 18, 1998)--Weeks Corporation (NYSE:WKS) today announced
the sale of $100 million of seven-year unsecured notes. The 6.875% notes, due
March 15, 2005, were priced to yield 6.942%. The Company expects the notes to be
rated BBB by Standard & Poor's, Baa2 by Moody's and BBB by Duff & Phelps.
Proceeds from the offering will be used to repay borrowings under the Company's
unsecured line of credit. In anticipation of the offering, and in connection
with funding decisions made regarding its acquisition and development
activities, the Company had entered into a treasury rate guarantee hedge
transaction in September 1997. The effect of this hedge is to increase the
effective interest rate on the notes to approximately 7.6%.

The managing underwriters for the offering were Goldman, Sachs & Co. and Morgan
Stanley Dean Witter.  The notes were offered pursuant to a registration
statement that has been declared effective by the Securities and Exchange
Commission, and application has been made to list the notes on the New York
Stock Exchange.  This press release shall not constitute an offer to sell or the
solicitation of an offer to buy, nor shall there be any sale of the notes in any
state in which such offer, solicitation or sale would be unlawful prior to
registration or qualification under the securities laws of any such state.
