                                    GUARANTEE


         GUARANTEE dated as of April 4, 1997, made by GWINNETT PRADO, L.P., a
Georgia limited partnership ("Guarantor"), in favor of Mill Creek Land, L.L.C.,
a Delaware limited liability Company (the "Company") and CORPORATE REALTY
CONSULTANTS, INC., a Delaware corporation (collectively, the "Beneficiaries"),
pursuant to the Limited Liability Company Agreement dated as of the date hereof,
between BUFORD ACQUISITION COMPANY, L.L.C., a Georgia limited liability company
(the "Member"), and CORPORATE REALTY CONSULTANTS, INC., as the same may be
amended, supplemented or modified from time to time (the "LLC Agreement").


         WHEREAS, the parties to the LLC Agreement have entered into a venture
to acquire and develop certain land located in Gwinnett County, Georgia;

         WHEREAS, pursuant to the LLC Agreement, the parties thereto have agreed
to make certain capital contributions to the Company as specified in Article III
of the LLC Agreement; and

         WHEREAS, as an inducement to the parties to enter into the LLC
Agreement and as a requirement thereunder, each party thereof has agreed to have
certain affiliates guarantee certain of its capital obligations.


         NOW, THEREFORE, in consideration of the premises and the covenants
contained herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Guarantor hereto agrees as
follows:


         1. Defined Terms. (a) Unless otherwise defined herein, capitalized
terms used in this Guarantee shall have the meanings assigned to them in the LLC
Agreement and the following terms have the following meanings:

         "Guarantee" means this Guarantee, as the same may be amended,
supplemented, waived or otherwise modified from time to time.
   2
                                                                               2



         "Obligations" means the due and punctual payment and performance of the
obligations of the Member under Section 3.02(b) and 3.03(a) of the LLC
Agreement.

         (b) The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and section and paragraph
references are to this Guarantee unless otherwise specified.

         (c) The meanings given to terms defined herein shall be equally
applicable to both the singular and plural forms of such terms.

         2. Guarantee. (a) Subject to the provisions of paragraph 2(b), the
Guarantor hereby unconditionally and irrevocably guarantees to the
Beneficiaries, for the benefit of the Beneficiaries and their respective
successors and assigns, the prompt and complete payment and performance by the
Member when due of the Obligations. Guarantor further agrees to pay any and all
expenses (including, without limitation, all reasonable fees and disbursements
of counsel) which may be reasonably paid or incurred by the Beneficiaries in
enforcing, or obtaining advice of counsel in respect of, any rights with respect
to, or collecting, any or all of the Obligations and/or enforcing any rights
with respect to, or collecting against, Guarantor under this Guarantee. This
Guarantee shall remain in full force and effect until the Obligations have been
satisfied or discharged in full.

         (b) No payment or payments made by any Person other than the Guarantor
or received or collected by the Company from the Member, any other guarantor or
any other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time or from time to time in reduction of or
in payment of the Obligations shall be deemed to modify, reduce, release or
otherwise affect the liability of Guarantor hereunder which shall,
notwithstanding any such payment or payments, remain liable for the Obligations
up to the maximum liability of such Guarantor hereunder until the Obligations
have been satisfied or discharged in full.

         3. Right of Set-Off. Upon the occurrence and during the continuance of
any failure of the Member to make a capital contribution as and when required
pursuant to Section 3.02(b) of the LLC Agreement, the Company is hereby
irrevocably authorized at any time and from time to time without notice to
Guarantor, any such notice being expressly 
   3
                                                                               3


waived by Guarantor to the extent permitted by applicable law, to set-off and
appropriate and apply any and all sums of money and other property at any time
held or owing by the Company to or for the credit or the account of Guarantor or
the Member, or any part thereof in such amounts as the Company may elect,
against and on account of the obligations and liabilities of Guarantor to the
Company hereunder, and claims of every nature and description of the Company
against Guarantor, whether arising hereunder, under the LLC Agreement, or
otherwise, as the Company shall elect, whether or not the Company has made any
demand for payment and although such obligations, liabilities and claims may be
contingent or unmatured. The Company shall notify Guarantor promptly of any such
set-off and the application made by the Company of the proceeds thereof;
provided that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of the Company under this Section are
in addition to other rights and remedies (which the Company may have under the
LLC Agreement).

         4. Limits on Subrogation. Notwithstanding anything to the contrary
contained herein or in the LLC Agreement and notwithstanding any payment or
payments made by Guarantor hereunder or pursuant to the LLC Agreement or any
right of set-off of the Company against Guarantor, Guarantor shall not be
entitled to be subrogated to any of the rights of the Beneficiaries against the
Member or any collateral security or guarantee or right of offset held by any
Beneficiaries for the payment of the Obligations, nor shall Guarantor seek or be
entitled to seek any contribution or reimbursement from the Member in respect of
payments made by Guarantor hereunder or under the LLC Agreement, until all
amounts owing to the Company by the Member on account of the Obligations are
paid in full. If any amount shall be paid to Guarantor on account of such
subrogation rights at any time when all of the Obligations shall not have been
paid in full, such amount shall be held by Guarantor in trust for the
Beneficiaries, segregated from other funds of Guarantor, and shall, forthwith
upon receipt by Guarantor, be turned over to the Company in the exact form
received by Guarantor (duly indorsed by Guarantor to the Company, if required),
to be applied against the Obligations.

         5. Amendments, etc. With Respect to the Obligations, Waiver of Rights.
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against Guarantor and without notice to or further assent
by Guarantor, any demand for payment of any of the Obligations made by the
Company may be rescinded by the Company and any of the Obligations continued,
and the Obligations, or the liability of any other Person upon or 
   4
                                                                               4



for any part thereof, may, from time to time, in whole or in part, be renewed,
extended, amended, modified, accelerated, compromised, waived, surrendered or
released by the Company, and the LLC Agreements and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Company may deem advisable from time to
time. When making any demand hereunder against the Guarantor, the Company may,
but shall be under no obligation to, make a similar demand on the Member, and
any failure by the Company to make any such demand or to collect any payments
from the Member shall not relieve Guarantor of its obligations or liabilities
hereunder, and shall not impair or affect the rights and remedies, express or
implied, or as a matter of law, of the Company against Guarantor. For the
purposes hereof, "demand" shall include the commencement and continuance of any
legal proceedings.

         6. Guarantee Absolute and Unconditional. Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof or reliance by the Beneficiaries upon this Guarantee or
acceptance of this Guarantee; the Obligations shall conclusively be deemed to
have been created, contracted or incurred, or renewed, extended, amended or
waived, in reliance upon this Guarantee; and all dealings between the Member and
the Guarantor, on the one hand, and the Beneficiaries, on the other hand,
likewise shall be conclusively presumed to have been had or consummated in
reliance upon this Guarantee. Guarantor waives diligence, presentment, protest,
demand for payment and notice of default or nonpayment to or upon the Member or
the Guarantor with respect to the Obligations. Guarantor understands and agrees
that this Guarantee shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity or
enforceability of the LLC Agreement, (b) any defense, set-off or counterclaim
which may at any time be available to or be asserted by the Member against the
Company or (c) any other circumstance whatsoever (with or without notice to or
knowledge of the Member or Guarantor) which constitutes, or might be construed
to constitute, an equitable or legal discharge of the Member for the
Obligations, or of Guarantor under this Guarantee, in bankruptcy or in any other
instance. When pursuing its rights and remedies hereunder against Guarantor, the
Company may, but shall be under no obligation to, pursue such rights and
remedies as it may have against the Member or any other Person, and any failure
by the Company to pursue such other rights or remedies or to collect any
payments from the Member or any such other Person or shall not relieve Guarantor
of any liability 
   5
                                                                              5



hereunder, and shall not impair or affect the rights and remedies, whether
express, implied or available as a matter of law, of the Company against
Guarantor.

         7. Reinstatement. This Guarantee shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any of the Obligations is rescinded or must otherwise be restored or returned by
the Beneficiaries upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Member or Guarantor, or upon or as a result of the
appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for, the Member or Guarantor or any substantial part of its property, or
otherwise, all as though such payments had not been made.

         8. Payments. Guarantor hereby agrees that payments hereunder will be
paid to the Company without set-off or counterclaim in U.S. Dollars at the
office of the Company.

         9. Representations and Warranties. (a) Guarantor hereby represents and
warrants that:

                  (i) it is a limited partnership duly formed, validly existing
         and in good standing under the laws of the jurisdiction of its
         formation and has the power and authority and the legal right to own
         and operate its property, to lease the property it operates and to
         conduct the business in which it is currently engaged;

                  (ii) it has the power and authority and the legal right to
         execute and deliver, and to perform its obligations under, this
         Guarantee, and has taken all necessary action to authorize its
         execution, delivery and performance of this Guarantee;

                  (iii) this Guarantee has been duly executed and delivered on
         behalf of Guarantor and constitutes a legal, valid and binding
         obligation of Guarantor enforceable against Guarantor in accordance
         with its terms, except as enforceability may be limited by bankruptcy,
         insolvency, fraudulent conveyance, reorganization, moratorium and other
         similar laws relating to or affecting the enforcement of creditors'
         rights generally, general equitable principles (whether enforcement is
         sought by proceedings in equity or at law) and an implied covenant of
         good faith and fair dealing;
   6
                                                                               6


                  (iv) the execution, delivery and performance of this Guarantee
         will not violate any provision of any requirement of law or contractual
         obligation of Guarantor in any respect that, in the aggregate for all
         such violations, could reasonably be expected to have a material
         adverse effect on the Guarantor and will not result in or require the
         creation or imposition of any lien on any of the properties or revenues
         of Guarantor pursuant to any such requirement of law or contractual
         obligation of Guarantor;

                  (v) no consent or authorization of, filing with, or other act
         by or in respect of, any arbitrator or governmental authority and no
         consent of any other Person (including, without limitation, any
         stockholder or creditor of Guarantor) is required in connection with
         the execution, delivery, performance, validity or enforceability of
         this Guarantee, other than those which have been duly obtained or made
         and are in full force and effect on the date of this agreement and
         except for those the absence of which in the aggregate, could not
         reasonably be expected to have a material adverse effect on the
         Guarantor;

                  (vi) no litigation, investigation or proceeding of or before
         any arbitrator or governmental authority is pending or, to the
         knowledge of Guarantor, threatened by or against Guarantor or against
         any of its properties or revenues (1) with respect to this Guarantee or
         any of the transactions contemplated hereby by (2) which could
         reasonably be expected to have a material adverse effect on the
         Guarantor.

         10. Covenants; Further Assurances. Guarantor hereby covenants and
agrees with the Beneficiaries that, from and after the date of this Guarantee
until payment in full of the Obligations at any time and from time to time, upon
the written request of the Company, and at the sole expense of Guarantor,
Guarantor will promptly and fully execute and deliver such further instruments
and documents and take such further actions as the Company may reasonably
request for the purpose of obtaining or preserving the full benefits of this
Guarantee and of the rights and powers herein granted.

         11. Notices. All notices, requests and demands to or upon the
Beneficiaries or Guarantor to be effective shall be in writing (or by telex, fax

                  (b) if to Guarantor, at its address or transmission number for

         may be hereafter notified by the respective parties hereto.

         The Beneficiaries and Guarantor may change their address and

         13. Severability. Any provision of this Guarantee which is prohibited

Guarantor with respect to the subject matter hereof and there are no promises or
representations by Guarantor or the Beneficiaries relative to the subject matter

         (b) The Beneficiaries shall not by any act (except by a written
instrument pursuant to paragraph 15(a) hereof), delay, indulgence, omission or
otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any breach of any of the terms and conditions hereof. No failure
to exercise, nor any delay in exercising, on the part of the Beneficiaries any
right, power or privilege hereunder shall operate as a waiver thereof. No single
or partial exercise of any right, power or privilege hereunder shall preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege. A waiver by the Beneficiaries of any right or remedy hereunder on
any one occasion shall not be construed as a bar to any right or remedy which
the Beneficiaries would otherwise have on any future occasion.

exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

                  (ii) consents that any such action or proceeding may be
         brought in such courts and waives any objection that it may now or
         hereafter have to the venue of any such action or proceeding in any
         such court or that such action or proceeding was brought in an
         inconvenient court and agrees not to plead or claim the same;

                  (iii) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage

         or at such other address of which the Beneficiaries shall have been
         notified pursuant thereto; and

                  (iv) agrees that nothing herein shall affect the right to
         effect service or process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction.

         (b) Guarantor and the Beneficiaries hereby unconditionally and
irrevocably waive, to the maximum extent not prohibited by law, any right they
may have to claim or recover in any legal action or proceeding referred to in
this Section any special, exemplary, punitive or consequential damages.

         18. Acknowledgments. Guarantor hereby acknowledges that:

         (a) it has been advised by counsel in the negotiation, execution and
delivery of this Guarantee; and

         (b) the Beneficiaries has no fiduciary relationship with or duty to it
or the Member arising out of or in connection with this Guarantee, and the
relationship between the Beneficiaries, on one hand, and the Guarantor and the
Member, on the other hand, in connection herewith is solely that of debtor and
creditor.

         19. WAIVERS OF JURY TRIAL. GUARANTOR HEREBY IRREVOCABLY AND

AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAW OF THE STATE OF NEW YORK.

Guarantee shall be for the benefit or enforceable by any creditor of the
Company. Except as expressly provided for herein, nothing in this Guarantee

instrument shall not be construed in any respect to be a contract in whole or in
part for the benefit of any third Person.
