                           PURCHASE AND SALE AGREEMENT


         THIS AGREEMENT is made and entered into as of the 22nd day of March,

and other good and valuable consideration, the receipt and sufficiency of which
are acknowledged by the parties to this Agreement, the parties agree to the
following terms and conditions:
         1. PURCHASE AND SALE. Subject to the terms of this Agreement, Seller
agrees to sell to Purchaser and Purchaser agrees to purchase from Seller the
following property (collectively, the "Property" or "Properties"):
                  1.1 Those fee and leasehold parcels of property located in

rentable square feet and 49 acres of land as more particularly described in

together with the projects presently under construction and Seller's rights with
respect to the "Allied Signal Option Parcel" as more particularly described in
Exhibit "1.1" as the "Development Assets" (collectively, the "Development

                  1.2 The land and all buildings, structures and other
improvements situated on the Realty (the "Improvements");
                  1.3 All fixtures, equipment, furnishings and other items of
property whatsoever used or useful in the operation, repair and maintenance of
the Realty, situated on the Realty, and owned by Seller (the "Personalty");

<PAGE>

                  1.4 All of the landlord's interest in and to tenant leases for
space in the Improvements or on the Realty;
                  1.5 All transferable contracts and agreements (each a
"Contract", and collectively, the "Contracts"), deposits, licenses, permits, and
contract rights pertaining to ownership, development and/or operation of the
Realty, the Improvements, the Personalty and the Development Assets;
                  1.6 All of Seller's rights in and to the name and all logos,
trademarks and other rights in connection with the name, and general intangible
rights pertaining to the ownership and/or operation of the Realty other than the
name "Highwoods" and any logos, trademarks, tradenames or other intangible
rights relating to the name "Highwoods"; and
                  1.7 All strips, gores, easements, privileges, rights-of-way,
riparian and other water rights, rights to lands underlying any adjacent streets
or roads, and other tenements, hereditaments and appurtenances, if any,
pertaining to or accruing to the benefit of the Realty, the Improvements and the
Development Assets.
        2. EFFECTIVE DATE. If this Agreement is not executed and delivered by
each party to it to all parties on or before March 25, 1999, at 5:00 p.m.,
Eastern time, then this Agreement shall be null and void and of no force or
effect. Execution and delivery shall be defined as the receipt of the fully
executed Agreement by the parties by means of the U.S. mails, delivery by a
nationally recognized overnight delivery service, hand delivery or facsimile
transmission. In the event delivery is by facsimile, the party delivering this
Agreement shall deliver to all other parties an original copy of the fully
executed Agreement within two (2) business days; failure to do so shall not
affect the validity of the execution and delivery of this Agreement. The date of
this Agreement,


                                        2
<PAGE>



for purposes of performance, shall be the date when the last one of Seller or
Purchaser has signed this Agreement, as stated on the signature page (the
"Effective Date").
        3. CLOSING DATE. Subject to other provisions of this Agreement for
extension or termination, the closing of the transactions contemplated by this
Agreement (the "Closing") shall be held at the offices of the attorneys for
Purchaser, Holland & Knight LLP, 701 Brickell Avenue, Miami, Florida 33131 on or
before May 19, 1999 (the "Closing Date"); provided, however, that, as to the
properties identified as "Gulf Atlantic Center" and "The 1800 Eller Drive
Building" on Exhibit "1.1" only, either Seller or Purchaser may, by written
notice to the other party, extend the Closing Date on said two (2) properties
for up to three (3) successive periods of thirty (30) days each, solely for the
purpose of satisfying the condition precedent in Section 13.2.2, but any such
extension shall not affect Purchaser's obligation to close in a timely manner
with respect to the other properties comprising the Property.

        4. DEPOSIT.

        4.1 To secure the performance by Purchaser of Purchaser's obligations
under this Agreement, Purchaser will deliver, within two (2) business days of
the Effective Date, to the law firm of Holland & Knight LLP, as escrow agent
("Escrow Agent"), the sum of One Million Dollars ($1,000,000.00) by wire
transfer to a depository designated by Escrow Agent, the proceeds of which shall
be held in trust as an earnest money deposit (the "Initial Deposit") by Escrow
Agent, and disbursed only in accordance with the terms of this Agreement. If
Purchaser elects not to cancel this Agreement during the Investigation Period,
as more particularly described in Section 11.2 of this Agreement, then, within
two (2) business days following the expiration of said Investigation Period,
Purchaser shall deliver to Escrow Agent a check or wire transfer in the sum of
Four Million Dollars


                                       3
<PAGE>


($4,000,000.00) (the "Additional Deposit") to be held together with, and upon
the same terms and conditions as, the Initial Deposit. Once the Additional
Deposit is paid to Escrow Agent, the term "Deposit" shall mean the Initial
Deposit plus the Additional Deposit; prior to such payment, whenever used in
this Agreement, the term "Deposit" shall mean only the Initial Deposit. In
addition, on the Closing Date, in the event that the extension respecting the
Gulf Atlantic Center and/or The 1800 Eller Drive Building properties is
exercised by either party, the aggregate $5,000,000.00 Deposit shall be applied
to the Purchase Price as provided in Section 5.2, and Purchaser shall be
obligated to make a new deposit in the amount of Two Hundred Fifty Thousand
Dollars ($250,000.00) for each such property for which the Closing Date is
extended, up to a maximum aggregate amount of $500,000.00, by wire transfer to
Escrow Agent on the Closing Date, which amount shall thereafter become the
"Deposit" for all purposes hereunder, and shall be applied to the portion of the
Purchase Price to be paid upon the closing of the Gulf Atlantic Center and/or
The 1800 Eller Drive Building properties or otherwise returned to Purchaser or
paid to Seller as provided herein.
        4.2 Escrow Agent shall use its reasonable efforts to invest the Deposit
in an interest bearing account or certificate of deposit maintained with or
issued by a commercial bank reasonably acceptable to Purchaser and Seller. All
interest accrued or earned on the Deposit shall be paid or credited to
Purchaser, except in the event of a default by Purchaser, without any default of
Seller, in which event the interest shall be disbursed to Seller, together with
the Deposit, as liquidated damages in accordance with Section 15.
        4.3 Purchaser and Seller acknowledge that, if the Deposit is at any time
in excess of $100,000.00, then the amount over $100,000.00 shall not be insured,
and both parties hold


                                       4
<PAGE>


Escrow Agent harmless from all losses and costs and liabilities which may accrue
or be incurred related to such lack of insurance.

5. PURCHASE PRICE.

        5.1 The total purchase price (the "Purchase Price") to be paid by
Purchaser to Seller for the Property is Two Hundred Forty-Nine Million
Thirty-Four Thousand Dollars ($249,034,000.00), plus an amount equal to the book
value of the Development Assets as described in Exhibit "1.1". For purposes of
this Agreement, "book value" is defined as $650,000.00 for the "Allied Signal
Option Parcel" and Seller's current cost basis as of the Closing Date,
determined using generally accepted accounting principles, as to the other
Development Assets. The Purchase Price shall be allocated among the Properties
within two (2) business days prior to the end of the Inspection Period, which
allocation, once completed, shall be attached to each copy of this Agreement as
Exhibit "5.1."

        5.2 The Purchase Price shall be paid to Seller as follows:

        $5,000,000.00,     the Deposit described in Section 4 of this Agreement,
                           which shall be paid to Seller at Closing;

        $244,034,000.00,   approximately, in cash at Closing, subject to
                           prorations and adjustments as provided in this
                           Agreement, to be paid by cashier's check or by wire
                           transfer; and

                           an amount equal to the book value of the Development
                           Assets as described in Section 5.1.

                  In the event that the extension respecting the Gulf Atlantic
Center and/or The Eller Drive Building properties is exercised by either party,
the Purchase Price payable hereunder shall be reduced by Seller's aggregate net
book value of the Gulf Atlantic and/or Eller Drive properties, and such amount
shall thereafter become the "Purchase Price" hereunder for the Gulf


                                       5
<PAGE>


Atlantic Center and/or The 1800 Eller Drive Building properties.

        6. CONFIDENTIAL NATURE OF AGREEMENT. Except for information obtained by
Purchaser from third parties or which is otherwise available to the public,
Purchaser shall keep all information obtained by Purchaser relative to the
Property (including, without limitation, the Due Diligence Documents), as it
relates to this transaction, confidential. Purchaser shall have the right to
disclose such information notwithstanding such limitation to Purchaser's
professionals, consultants, lenders, officers, employees, stockholders,
purchasers and affiliates for the sole purpose of evaluating the Property to
determine its value and suitability for Purchaser's needs and financing and as
may be required by applicable law. Seller shall have the right, in its sole
discretion, to terminate this Agreement in the event of a material breach by
Purchaser of this Section 6, whereupon Escrow Agent, subject to the provisions
of Section 11.3, shall return the Deposit, together with all interest earned
thereon, to Purchaser, and both parties shall be released from all further
obligations under this Agreement, except for those which expressly survive such
termination.

        7. TITLE EVIDENCE. Within fifteen (15) days following the Effective
Date, Purchaser shall, at Purchaser's expense, obtain an ALTA marketability
title insurance commitment (the "Commitment"), with fee and leasehold owner's
title policy premium to be paid by Purchaser at Closing, issued by Holland &
Knight LLP, as agent for one or more national title insurers acceptable to
Purchaser (collectively, the "Title Insurer"), with hard copies of all
exceptions. The Commitment shall show Seller to be vested with good and
marketable and insurable fee simple or leasehold title to the Realty and the
Development Assets other than the Allied Signal Option Parcel, insurable in an
amount equal to the Purchase Price in accordance with the standards adopted from


                                       6
<PAGE>

time to time by The Florida Bar, at standard rates, and Seller believes that the
Commitment will show the Realty and the Development Assets other than the Allied
Signal Option Parcel to be free and clear of all liens, encumbrances, leases,
tenancies, covenants, conditions, restrictions, rights-of-way, easements and
other matters affecting title, except the following (which, if not objected to
by Purchaser pursuant to the terms of Article 9 below, shall be deemed the
"Permitted Exceptions"):

        7.1 Ad valorem real estate taxes for 1999 and subsequent years;

        7.2 All applicable zoning ordinances and regulations;

        7.3 Matters of record which are common to the subdivision;

        7.4 Matters described in Seller's existing title policies with respect
to the Properties, including, with respect to the Gulf Atlantic Center and The
1800 Eller Drive Building properties, the ground leases (collectively, the
"Ground Leases") pursuant to which Seller obtained its leasehold interest in the
subject Realty; and

        7.5 Tenants in possession.

    8. SURVEY.

        8.1 Within the time period for providing the Commitment, Purchaser shall
obtain and deliver to Seller ALTA surveys (the "Surveys") of the Realty and the
Improvements. The Surveys shall:

                  8.1.1 meet the minimum technical standards of the Florida
Board of Land Surveyors;

                  8.1.2 be certified to Purchaser, to Purchaser's attorney, to
the Title Insurer and to Purchaser's mortgage lender;



                                       7
<PAGE>


                  8.1.3 be certified (or recertified) as of a date subsequent to
the Effective Date;

                  8.1.4 set forth the total number of square feet and acres in
the Realty;

                  8.1.5 show the location of all improvements, parcels (if any)
in the legal descriptions of the Realty, number of square feet and parking
spaces in the Improvements, utility, setback and other lines; easements, either
visible or recorded, and recording references of them; and

                  8.1.6 include elevation and flood zone information.

             8.2 If the Survey shall reflect any encroachments, overlaps,
unrecorded easements or similar rights in third parties, or any other adverse
matters not specifically provided for in this Agreement, then the same shall be
deemed "title defects" as set forth in Section 9.


     9. TITLE DEFECTS.

        9.1 Purchaser shall have until April 21, 1999 in which to examine the
Commitment and the Surveys. If Purchaser finds title to be defective, Purchaser
shall, no later than 5:00 p.m. Eastern time on April 21, 1999, notify Seller in
writing, specifying the title defect(s). If Purchaser fails to give Seller
written notice of any title defect(s) before 5:00 p.m. Eastern time on April 21,
1999, the defects shown in the Commitment or the Surveys shall be deemed to be
waived as title objections to closing this transaction.

        9.2 If Purchaser has given Seller timely written notice of defect(s) and
the defect(s) render the title other than as represented in this Agreement or if
any new defects appear from the date of the Commitment through the Closing Date,
Seller shall use commercially reasonable efforts to cause only those defects
recorded after October 7, 1997 to be cured by the Closing Date. Seller agrees to
remove, by payment, bonding or otherwise, any such lien (other than


                                       8
<PAGE>



environmental liens) against the Property capable of removal by the payment of
money or bonding. Seller shall not be obligated to (but may, in its sole and
absolute discretion) cure any other defect or to buyout or settle any other
claim or lien against the Property. At Seller's option, the Closing Date may be
extended for a period not to exceed sixty (60) days for purposes of eliminating
such title defects. If such additional time is reasonably required by Seller to
cure such title defects, Seller's failure to extend the Closing Date shall be
commercially unreasonable.

        9.3 If Seller does not eliminate such defects as of the Closing Date, as
the same may be extended under the preceding sentence, or if any new "title
defects" appear between the date of the Commitment through the Closing Date
which Seller does not eliminate as of the Closing Date, Purchaser shall have the
option to:

                  9.3.1 Close and accept the title "as is," without reduction in
the Purchase Price and without claim against Seller for such title defects
(except for any lien that Seller is required to cure pursuant to Section 9.2
that can be removed by the payment of money or bonding, for which credit shall
be given Purchaser at the Closing unless Seller pays the same at the Closing)
(and in such event, the Closing shall take place on the Closing Date); or

                  9.3.2 Cancel this Agreement, whereupon Escrow Agent, subject
to the provisions of Section 11.3, shall return the Deposit, together with all
interest earned thereon, to Purchaser, and both parties shall be released from
all further obligations under this Agreement, except for those which expressly
survive such termination, unless such title defects were caused by Seller's
willful act or willful omission, in which event Seller shall remain liable to
Purchaser for damages caused by such title defects.

        10. EXISTING LEASES. Seller represents and warrants to Purchaser that
attached to



                                       9
<PAGE>



this Agreement as Exhibit "10" is a rent roll of all leases, tenancies, and
other occupancies, whether written or oral, affecting all or any portion of the
Property (the "Leases"), setting forth, for each tenant (each a "Tenant", and
collectively, the "Tenants"), the name of the tenant, the space(s) affected, the
rents, the lease term, the security deposit as required by the subject Lease, if
any, prepaid rent and any rent arrearages. Upon execution of this Agreement by
Seller, Seller shall deliver to Purchaser true, correct and complete copies of
all of the Leases. Seller further represents and warrants to Purchaser that:

        10.1 No other parties have any rights of occupancy or possession
(including, without limitation, renewal options, rights of first refusal,
options to purchase, free rent, tenant improvement allowances or other special
concessions) of all or any portion of the Property except as set forth in the
rent roll which is a part of Exhibit "10" or as set forth in the lease files
provided by Seller to Purchaser pursuant to Section 11.1;

        10.2 All of the Leases are, as of the date of this Agreement, in good
standing, without default on the part of Seller, and shall remain without
default on the part of Seller through the date of the Closing;

        10.3 Seller shall use its diligent, good-faith, commercially reasonable
efforts to deliver to Purchaser, at least ten (10) days prior to the Closing,
appropriate estoppel letters from all Tenants occupying more than 10,000 square
feet ("Major Tenants") and from a sufficient number of Tenants occupying the
remaining occupied square feet in the Property, and not occupied by Major
Tenants, necessary to provide estoppel coverage on eighty percent (80%) of the
occupied square footage in the Property, such estoppel letters to confirm in all
material respects the information contained in Exhibit "10" and provided to
Purchaser by Seller pursuant to Sections 11.1.5 and



                                       10
<PAGE>


11.1.6 and to be in the form attached hereto as Exhibit "10.3". If the estoppel
letters required by the preceding sentence are not timely obtained after
diligent effort by Seller, then Seller shall execute an affidavit as to each
such Lease for which it has not obtained an estoppel letter, setting forth the
information which would have been contained in the estoppel letter, which shall
substitute for such missing estoppel letters until such time as estoppel letters
are received from the subject Tenants; provided, however, that Seller shall not
be obligated to give, and Purchaser shall not be obligated to accept, substitute
affidavits for more than 100,000 occupied square feet in the aggregate with
respect to missing estoppel letters from Major Tenants. If Seller is unable to
comply with the provisions of this Section 10.3 by the Closing Date, Purchaser
shall have the options set forth in Sections 14.1 and 14.2;

        10.4 There are no modifications, understandings or agreements with
respect to the Leases except as reflected in the Leases or as set forth in the
lease files provided by Seller to Purchaser may be disclosed to Purchaser
pursuant to Section 11.1;

        10.5 Seller has not received any prepaid rent under any of the Leases
except as may be disclosed to Purchaser in the rent roll which is part of
Exhibit "10"; and

        10.6 Seller shall not accept payment of any rent under any Lease for
more than one (1) month in advance. Seller shall have the right, prior to the
end of the Inspection Period, to modify any existing Lease or Contract and enter
into any new lease or agreement affecting all or any portion of the Property,
provided that Seller shall give Purchaser prompt notice of any such modification
or new lease or agreement, and provided further that Seller shall not exercise
its option, or enter into any lease respecting, the Allied Signal Option Parcel
without Purchaser's prior written consent, which shall not be unreasonably
withheld or delayed. After the end of the



                                       11
<PAGE>


Investigation Period, Seller shall modify any existing Lease or Contract or
enter into any new lease or agreement affecting all or any portion of the
Property only with the prior written consent of Purchaser, which shall not be
unreasonably withheld. Seller shall immediately provide to Purchaser a copy of
any such proposed modification, lease or agreement, and Purchaser shall have two
(2) business days from the delivery thereof in which to withhold its consent to
the terms thereof in writing, if it so chooses, or else the same shall be deemed
consented to by Purchaser. If Purchaser timely withholds its consent, Purchaser
shall have the right to terminate this Agreement, whereupon Escrow Agent,
subject to the provisions of Section 11.3, shall return the Deposit, together
with all interest earned thereon, to Purchaser, and both parties shall be
released from all further obligations under this Agreement, except for those
which expressly survive such termination. If Purchaser elects not to terminate
this Agreement at the end of the Investigation Period, all new leases and
agreements entered into by Seller prior to the end of the Investigation Period
shall become "Leases" and "Contracts," respectively, hereunder. In addition, all
new leases and agreements entered into by Seller after the end of the
Investigation Period with Purchaser's consent or deemed consent shall become
"Leases" and "Contracts," respectively, hereunder.

         11.      INVESTIGATION PERIOD.
                  11.1 During the period from the Effective Date until April 23,
1999 (the "Investigation Period"), Purchaser shall have the right to conduct, at
Purchaser's expense, whatever reasonable investigations, analyses and studies of
the Property that Purchaser may deem appropriate to satisfy Purchaser with
regard to:

                  11.1.1 the physical condition of the building(s) and other
improvements included in the Property, including their structure, roofs, air
conditioning, heating, electrical,


                                       12
<PAGE>

 plumbing and other mechanical systems;

                  11.1.2 the physical condition of all fixtures, equipment,
furnishings and other items of property referred to in Subsection 1.3 above, an
inventory of which shall be furnished by Seller at Seller's expense within
fifteen (15) days after the Effective Date;

                  11.1.3 the permitted uses of and improvements to the Property
under applicable building and zoning ordinances and the present compliance or
non-compliance with the same;

                  11.1.4 evidence of any hazardous waste or similar materials,
and of Radon, in, on, under or about the Property;

                  11.1.5 all existing Contracts, Leases, lease files, lease
abstracts, historical MRI reports (not including prospective information, such
as budget projections, which are proprietary to Seller) and tenancies affecting
the Property; and

                  11.1.6 Seller's historical operating statements for calendar
year 1998 and year-to-date 1999 (as and when available).

        11.2 Purchaser and its agents and employees shall have the right to
enter upon the Property for the purpose of making inspections, at Purchaser's
sole risk, cost and expense, and subject to the rights of tenants. No
destructive testing shall be permitted. All of such entries upon the Property
shall be at reasonable times during normal business hours and after at least one
(1) business day's prior notice to Seller or Seller's agent, and Seller or
Seller's agent shall have the right to accompany Purchaser during any activities
performed by Purchaser on the Property. Seller shall make available to Purchaser
at all times during business hours during the Investigation Period, and after
the Investigation Period until the Closing Date, upon one (1) business day's
prior notice, all



                                       13
<PAGE>




documents relating to the matters described in Section 11.1 above which are in
Seller's possession for review and copying by Purchaser (the "Due Diligence
Documents"). In addition, within five (5) business days after the Effective
Date, Seller shall provide Exhibits "12.1" and "12.6" to Purchaser. Purchaser
shall promptly provide to Seller copies of all environmental and engineering
reports which Purchaser may obtain from third parties relating to the Property.
If Purchaser is dissatisfied, for any reason and in Purchaser's exclusive
judgment, with the result of Purchaser's investigations, then Purchaser may
cancel this Agreement by notifying Seller of such cancellation on or before 5:00
p.m. on April 23, 1999, whereupon Escrow Agent, subject to the provisions of
Section 11.3, shall return the Deposit, together with all interest earned
thereon, to Purchaser, and both parties shall be released from all further
obligations under this Agreement, except for those which expressly survive such
termination.

        11.3 If Purchaser or Seller cancels this Agreement pursuant to the terms
hereof, Purchaser shall deliver to Seller all of the Due Diligence Documents.
Upon receipt of said documents by Seller, Escrow Agent shall disburse the
Deposit, together with all interest earned thereon, to Purchaser.

        11.4 Upon Purchaser's waiver of or failure to duly exercise its right to
terminate described in this Section 11, Purchaser shall have accepted the
Property "as is", with no representations or warranties regarding the Property
other than any which may be specifically stated in this Agreement.

        11.5 Notwithstanding any provisions in this Agreement to the contrary,
Purchaser does and shall indemnify and hold harmless Seller and its agents,
employees, successors and assigns, to the extent of the Deposit, against all
losses, claims, damages, liability, attorneys' and


                                       14
<PAGE>

accountants' fees and costs of litigation and all other expenses related to,
growing out of, or arising from the investigation of or entry upon the Property,
or other acts undertaken by Purchaser or its agents, employees or assigns, under
this Agreement, including, without limitation, mechanic's or materialmen's
liens. If Purchaser does not close on the purchase of the Property under this
Agreement, it shall return the Property to the condition in which it existed
prior to any investigations undertaken by Purchaser or its agents, employees and
assigns pursuant to this Agreement.

        11.6 Except as otherwise expressly provided herein, Seller makes no
representations or warranties as to the accuracy or completeness of the Due
Diligence Documents.

        11.7 The inspections under this Section 11 may include a Phase I
environmental inspection of the Property, but no Phase II environmental
inspection shall be performed without the prior written consent of Seller, which
may be withheld in its sole and absolute discretion, and if consented to by
Seller, the proposed scope of work and the party who will perform the work shall
be subject to Seller's review and approval. Upon Seller's request, Purchaser
shall deliver to Seller copies of any Phase II or other environmental report to
which Seller consents as provided above. Purchaser, for itself and any entity
affiliated with Purchaser, waives and releases Seller and its employees, agents,
officers, trustees, directors, beneficiaries and partners from and against any
claims, demands, penalties, fines, liabilities, settlements, damages, costs or
expenses of whatever kind or nature, known or unknown, existing and future,
contingent or otherwise (including any action or proceeding, brought or
threatened, or ordered by any appropriate governmental entity) made, incurred,
or suffered by Purchaser or any entity affiliated with Purchaser relating to the
presence, misuse, use, disposal, release or threatened release of any hazardous
or toxic materials, chemicals or wastes as the Property and any liability or
claim related to the Property arising under


                                       15
<PAGE>

the Comprehensive Environmental Response, Compensation, and Liability Act of
1980, the Superfund Amendments and Reauthorization Act of 1986, the Resource
Conservation and Recovery Act, and the Toxic Substance Control Act, all as
amended, or any other cause of action based on any other state, local, or
federal environmental law, rule or regulation; provided, however, the foregoing
release shall not operate or release any claim by Purchaser against any person
or entity other than described above in this Section 11.7. The provisions of
this Section 11.7 shall survive indefinitely the Closing or any termination of
this Agreement and shall not be merged into the closing documents.

        11.8 To the maximum and extent permitted by applicable law, and except
for Seller's representations and warranties (collectively, "Seller's
Warranties") in this Agreement and the documents of conveyance and assignment to
be delivered at the Closing, this sale is made and will be made without
representation, covenant, or warranty of any kind (whether express, implied, or,
to the maximum extent permitted by applicable law, statutory) by Seller. As a
material part of the consideration of this Agreement, Purchaser agrees to accept
the Property on an "AS IS" and "WHERE IS" basis, with all faults and any and all
latent and patent defects, and without any representation or warranty, all of
which Seller hereby disclaims, except for Seller's Warranties. Except for
Seller's Warranties, no warranty or representation is made by Seller as to (a)
fitness for any particular purpose, (b) merchantability, (c) design, (d)
quality, (e) condition, (f) operation or income, (g) compliance with drawings or
specifications, (h) absence of defects, (i) absence of hazardous or toxic
substances, (j) absence of faults, (k) flooding, or (1) compliance with laws and
regulations including, without limitation, those relating to health, safety, and
the environment. Purchaser acknowledges that Purchaser has entered into this
Agreement with the intention of


                                       16
<PAGE>


making and relying upon its own investigation of the physical, environmental,
economic use, compliance and legal condition of the Property and that, except as
otherwise provided in this Agreement, Purchaser is not now relying, and will not
later rely, upon any representations and warranties made by Seller or anyone
acting or claiming to act, by, through or under or on Seller's behalf concerning
the Property. The provisions of this paragraph shall survive indefinitely the
Closing or any termination of this Agreement and shall not be merged into the
closing documents.

     12. REPRESENTATIONS, WARRANTIES AND COVENANTS. Seller represents and
warrants to Purchaser, to Seller's knowledge, and covenants and agrees with
Purchaser as follows:

        12.1 Seller has not entered into any contracts, subcontracts,
arrangements, licenses, concessions, easements or other agreements, either
recorded or unrecorded, written or oral, affecting all or any portion of the
Property, or the use of it, other than the Leases set forth in Exhibit "10" and
those agreements set forth in Exhibit "12.1";

        12.2 There are no (i) existing or pending improvement liens affecting
the Property; (ii) violations of building codes and/or zoning ordinances or
other governmental or regulatory laws, ordinances, regulations, orders or
requirements affecting the Property; (iii) existing, pending or threatened
lawsuits or appeals of prior lawsuits affecting the Property; (iv) existing,
pending or threatened condemnation proceedings affecting the Property; or (v)
existing, pending or threatened zoning, building or other moratoria, downzoning
petitions, proceedings, restrictive allocations or similar matters that could
affect Purchaser's use of the Property;

        12.3 Seller is vested with good and marketable title to all fixtures,
equipment, furnishings and other items of property referred to in Section 1 and
owned by Seller, free of all


                                       17
<PAGE>


financing and other liens or encumbrances;

        12.4 Seller shall maintain the Property in the same manner as it has
been maintained prior to the Effective Date until the Closing Date and shall
comply prior to the Closing in all material respects with all laws, rules,
regulations, and ordinances of all governmental authorities having jurisdiction
over the Property;

        12.5 There is no radon in the Improvements which are above government
approved levels; Seller has not done nor allowed anything which could cause
toxic or hazardous materials or waste to be present in, on or about the
Property, and has no knowledge of any such materials or waste being or ever
having been in, on, or about the Property or adjacent properties, in each case,
except as described in Exhibit "12.6" attached hereto, which, for purposes
hereof, constitutes all of Seller's knowledge;

        12.6 Seller shall provide, and keep in force through the Closing,
policies of fire, flood, windstorm, hazard and other casualty insurance on the
improvements portion of the Realty and all items of other property referred to
in Section 1 above;

        12.7 There are no agreements currently in effect which restrict the sale
of the Property;

        12.8 Subject to approval of Seller's Board of Directors as provided in
this Section 12.8, Seller has the right, power and authority to execute and
deliver this Agreement and to consummate the transactions contemplated hereby;
neither the execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby nor the fulfillment of nor the compliance with
the terms, conditions and provisions of this Agreement will conflict with or
result in a violation or breach of Seller's partnership agreement, or any other
instrument or


                                       18
<PAGE>


agreement of any nature to which Seller is a party or by which it is bound or
may be affected, or constitute (with or without the giving of notice or the
passage of time) a default under such an instrument or agreement; no consent,
approval, authorization or order of any person is required with respect to the
consummation of the transactions contemplated by this Agreement. Seller agrees
to present the terms of this Agreement to its Board of Directors (the "Board")
for its approval not later than March 23, 1999. Seller further agrees to notify
Purchaser of the decision of such Board no later than the end of business on
such date. A Board decision to approve this transaction shall be final except
that in the event of a material change in a term as embodied in this Agreement,
the parties acknowledge that such change in terms may be subject to
reconsideration by the Board, at its election.

        12.9 No commitments or agreements have been or will be made by or on
behalf of Seller to any governmental authority, utility company, school board,
church or other religious body, any homeowners or homeowners' association, or
any other organization, group or individual, relating to the Property which
would impose an obligation upon Purchaser to make any contributions or
dedications of money or land to construct, install or maintain any improvements
of a public or private nature on or off the Realty or the Development Assets, or
otherwise impose liability on Purchaser.

        12.10 The Ground Leases are, as of the date of this Agreement, in good
standing, without default on the part of Seller, and have not been modified,
changed, altered or amended in any respect since Seller acquired its leasehold
interest in the Ground Leases, and the lessors under the Ground Leases are not
in default, nor has there occurred any event which, by lapse of time or
otherwise, will result in any default under the Ground Leases.

                                       19
<PAGE>


        12.11 At all times during the term of this Agreement and as of the
Closing, all of Seller's representations, warranties and covenants in this
Agreement shall be true and correct; no representation or warranty by Seller
contained in this Agreement and no statement delivered or information supplied
to Purchaser pursuant to this Agreement contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements or information contained in them or in this Agreement not misleading.

        For purposes of this Section 12, "to Seller's knowledge" shall mean the
actual knowledge of Troy Cox, James Heistand, Dale Johannes and Richard Nash,
without independent inquiry.

        Purchaser warrants and represents to Seller that Purchaser has the
right, power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated by it, neither the execution and
delivery of this Agreement nor the consummation of the transactions contemplated
by it nor the fulfillment of nor the compliance with the terms, conditions and
provisions of this Agreement will conflict with or result in a violation or
breach of Purchaser's organizational documents, or any other instrument or
agreement of any nature to which Purchaser is a party or by which it is bound or
may be affected, or constitute (with or without the giving of notice or the
passage of time) a default under such an instrument or agreement; no consent,
approval, authorization or order of any person is required with respect to the
consummation of the transactions contemplated by this Agreement. At all times
during the term of this Agreement and as of the Closing, all of Purchaser's
representations, warranties and covenants in this Agreement shall be true and
correct.

     13. CONDITIONS PRECEDENT.

                                       20
<PAGE>



        13.1 An express condition precedent to Purchaser's obligation to close
this transaction is the truth and correctness of all of Seller's representations
and warranties and the fulfillment of all of Seller's covenants at all times
during the term of this Agreement and as of the Closing, and no inquiry,
analysis or examination made by Purchaser (or the results of them) shall reduce,
limit or otherwise affect said representations, warranties and covenants.

        13.2 The following items are additional conditions precedent to
Purchaser's obligation to close the transactions contemplated by this Agreement:


                  13.2.1 The Property shall remain zoned at the time of the
Closing so as to permit each and every use now being made of the Property; there
shall be no additional limiting conditions or restrictions under any zoning
resolution, ordinance, covenant, agreement, or the like that could prohibit or
frustrate any use of the Property now being made or otherwise permissible under
said zoning classification in the absence of such conditions or restrictions.


                  13.2.2 As to the Gulf Atlantic Center and The 1800 Eller Drive
Building properties only, Purchaser shall have received consents to the
assignment of the lessee's interests under the Ground Leases by Seller and the
assumption thereof by Purchaser, and Purchaser shall also have received estoppel
certificates from the ground lessors under the Ground Leases in form and
substance reasonably satisfactory to Purchaser; provided, however, that if one
or both of such consents are not received by the Closing Date and Seller or
Purchaser extends the Closing Date as to the Gulf Atlantic Center and/or The
1800 Eller Drive Building properties, the foregoing shall be a condition to
closing of the Gulf Atlantic Center and/or The 1800 Eller Drive Building
properties only.

        14. DEFAULT BY SELLER. Prior to the Closing Date, in the event that
Purchaser

                                       21
<PAGE>


becomes aware of facts or circumstances indicating that a representation or
warranty of Seller contained herein is inaccurate, untrue or breached, as the
case may be, Purchaser shall promptly so notify Seller in writing, and Seller
shall have the right to cure the same on or before the Closing Date, failing
which Purchaser shall have the right, by written notice to Seller given on the
Closing Date, to terminate this Agreement, whereupon Escrow Agent, subject to
the provisions of Section 11.3, shall return the Deposit, together with all
interest earned thereon, to Purchaser, and both parties shall be released from
all further obligations hereunder, except for those which expressly survive such
termination. If any of Seller's representations and warranties are not true and
correct in all material respects as of the Closing Date or Seller's covenants
are not fulfilled in all material respects or all other conditions precedent are
not met in all material respects as of the Closing (or earlier specified date,
if any), or if Seller fails to perform any of the terms and conditions of this
Agreement in all material respects or is otherwise in default under this
Agreement, then Purchaser, at Purchaser's sole option, may elect to:

        14.1 Waive the default or failure and close "as is"; or

        14.2 Cancel this Agreement by written notice to Seller given on or
before the Closing Date, whereupon Escrow Agent, subject to the provisions of
Section 11.3, shall return the Deposit, together with all interest earned
thereon, to Purchaser, and both parties shall be released from all further
obligations under this Agreement, except for those which expressly survive such
termination, unless the default was caused by the willful act or willful
omission of Seller, in which event Seller shall continue to be liable for
damages and attorneys' fees caused by such default); or

        14.3 Seek specific performance of Seller's obligations under this
Agreement.

        In the event that any representation or warranty made by Seller herein
is found to be


                                       22
<PAGE>

inaccurate, untrue or breached, as the case may be, after the Closing Date,
Purchaser shall have the right, for a period of one (1) year after the Closing
Date, to seek actual (but not consequential or punitive) damages from Seller;
provided, however, that Purchaser must commence a legal action or proceeding
seeking such damages within said one (1)-year period, or its claims shall
thereafter be barred.

     15. DEFAULT BY PURCHASER. In the event of the failure or refusal of
Purchaser to close this transaction, Escrow Agent shall pay to Seller the
Deposit, together with all interest earned thereon, as agreed and liquidated
damages for said breach, and as Seller's sole and exclusive remedy for default
of Purchaser, whereupon this Agreement shall terminate and both parties shall be
released from all further obligations under this Agreement, except for those
which expressly survive such termination.

     16. PRORATIONS.

        16.1 Real estate and personal property taxes and ground rents under the
Ground Leases shall be prorated as of midnight of the day before the Closing
Date. In the event that the taxes for the year of the Closing are unknown, the
tax proration will be based upon such taxes for the prior year and, at the
request of either party, such taxes for the year of the Closing shall be
reprorated and adjusted when the tax bill for the year of the Closing is
received and the actual amount of taxes is known.

        16.2 Utility bills or charges, where applicable, shall be prorated as of
midnight of the day before the Closing Date. The parties shall, to the extent
reasonably possible, have utility meters read the day preceding the Closing Date
and Seller shall be responsible for paying all utility bills or charges which
accrued against the Property prior to midnight of the day before the Closing


                                       23
<PAGE>


Date and Purchaser shall be required to pay all utility bills or charges
accruing against the Property on or subsequent to midnight of the day before the
Closing Date, with any charge for which a reading could not be made as of the
day preceding the Closing Date being prorated as of midnight of the day before
the Closing Date using an estimate based on the most recent reading for such
utility. Purchaser shall, as of the day prior to the Closing Date, post with
each utility company such deposit as each such utility company shall require, to
the end that Seller's utility deposits shall be refunded to Seller following the
Closing, after appropriate charge for Seller's utility bills. Purchaser shall
secure its own insurance on the Property as of the Closing Date, and Seller
shall cancel all existing insurance policies as of the Closing Date. Purchaser
and Seller shall, before and after the Closing, reasonably cooperate with each
other in connection with this Section 16.2.

        16.3 The parties agree that, except as otherwise specifically stated
elsewhere in this Agreement, all income and expenses of the Property are
intended to be prorated as of midnight of the day before the Closing Date.
Purchaser shall be deemed the owner of the Property, for the purpose of such
calculation, for the entire Closing Date. Income shall include all revenue of
Seller derived from the operation of the Property. Expenses shall include all
expenses from the operation of the Property. Income actually received by Seller
prior to the Closing in payment for a period subsequent to the Closing shall
appear on the closing statement as a credit to Purchaser. Expenses actually paid
by Seller prior to the Closing in payment for a period subsequent to the Closing
shall appear on the closing statement as a credit to Seller.

        16.4 Notwithstanding anything to the contrary in Section 16.3 above,
rents under the Leases, including, without limitation, fixed rent and additional
rent, including operating expense and real estate tax pass-throughs
(collectively, "Rents"), shall be addressed in the manner set forth in


                                       24
<PAGE>


this Section 16.4. All collected Rents for the month in which the Closing occurs
shall be prorated as of midnight the day before the Closing Date. All
uncollected Rents for the months prior to the month in which the Closing occurs
and all uncollected Rents for the month of the Closing (the "Delinquent Rents"),
shall remain Seller's property, and Seller shall receive no proration credit
therefor at the Closing. Purchaser, however, shall receive a proration credit
for its prorated portion of all Rents for the month of the Closing whether such
Rents have been collected or remain uncollected. All prepaid Rents (for the
months following the Closing) paid to or in possession of Seller shall be
credited to Purchaser at the Closing. Purchaser agrees to use good faith and
commercially reasonable efforts, for a period of six (6) calendar months after
the Closing, to collect Delinquent Rents from each tenant ("Tenant or Tenants")
remaining in possession of its space under a Lease. If any Tenant identifies in
writing at the time of payment what its payment is for or how such payment
should be applied, such payment shall be used or applied in such manner. Any and
all other amounts received by Purchaser from any party owing the Delinquent
Rents which are received by Purchaser after the Closing Date shall first be
applied to the Rent due for the then current month, then to Purchaser's
reasonable collection costs (including reasonable attorneys' fees and costs),
then to accrued obligations of such Tenant due prior to the Closing (in the
order of accrual), and then to accrued obligations due after the Closing.
Purchaser shall promptly deliver to Seller any funds to be applied to Delinquent
Rents in accordance with the preceding sentence. No portion of Delinquent Rents
attributable to a particular Tenant shall be applied against the Rents or
Delinquent Rents attributable to another Tenant, or the expenses incurred by
Purchaser in collecting such Rents or Delinquent Rents from other Tenants.
Purchaser shall not be obligated to file suit to collect the Delinquent Rents.
After the Closing, Seller shall be entitled to commence and/or


                                       25
<PAGE>


continue any collection efforts against any Tenants owing Delinquent Rents,
including, but not limited to, commencing and/or continuing prosecuting lawsuits
against such Tenants, so long as such lawsuits are for money damages only and do
not seek the remedy of eviction.

        16.5 All security deposits or prepaid Rent held by or under the control
of Seller, as required by the Leases, reflected on the tenant estoppel letter
with respect to the Leases and as set forth on Exhibit "10" (less any offsets
indicated thereon as hereinafter defined, if applicable), shall be paid or
credited to Purchaser as of the Closing Date, and Purchaser shall, with respect
to all matters arising or accruing after the Closing, assume all liability
therefor. Seller shall not, after the Effective Date and prior to the Closing,
further offset all or any portion of such security deposits or prepaid Rent
without the prior written consent of Purchaser.

                  16.6 Except as otherwise provided in this Agreement, any lease
commissions or tenant improvement costs which are (i) incurred by Seller in
connection with any existing Leases or new leases entered into prior to the end
of the Investigation Period or entered into after the end of the Investigation
Period and approved by Purchaser in writing; or (ii) associated with currently
existing renewal, expansion or refusal rights of Tenants under the Leases
exercised after the Effective Date but prior to the Closing shall be prorated
between the parties in proportion to the percentage of the Lease term in the
case of (i) above, or the renewal or expansion term or term applicable to the
expansion or refusal rights in the case of (ii) above, which falls before

and the percentage of same which falls after midnight of the day before the
Closing Date (which shall be Purchaser's portion). Any other lease commissions
or tenant improvement costs incurred by Seller in connection with the Leases
shall be the responsibility of Seller; provided, however, that Purchaser shall
bear the cost of


                                       26
<PAGE>


any lease commissions or tenant improvement costs associated with currently
existing renewal, extension, expansion or refusal rights of Tenants under the
Leases exercised after the Closing.

        16.7 Seller agrees to pay to the appropriate taxing authority sales tax
collected by Seller in connection with Rent received by Seller under the Leases

than one hundred twenty (120) days after the Closing Date, Seller shall deliver
to Purchaser the receipt or certificate from the Florida Department of Revenue
provided for in Section 212.10(1), Florida Statutes (such as a "letter of good
standing"), evidencing that the sales taxes for such month and for previous
months have been paid in full and that no interest or penalties are due in
connection with same.

        16.8 Notwithstanding anything to the contrary which may be contained
herein:

                  16.8.1 Seller and Purchaser acknowledge and agree that to the
extent the annual reconciliation of pass-throughs for the 1998 calendar year are
not completed prior to the Closing, Seller, rather than Purchaser, shall have
the right and obligation to complete such reconciliations and to collect and
retain reimbursements from Tenants or pay reimbursements to Tenants, as
applicable.

                  16.8.2 Upon the annual reconciliation of such pass-throughs
with the Tenants of the Property for the 1999 calendar year, (i) if such
reconciliation results in there being refunds due and payable to the Tenants,
Seller shall promptly pay to Purchaser, upon Purchaser's request (accompanied by
appropriate documentation), Seller's share of such refund amounts prorated for
the portion of the year during which Seller owned the Property, and (ii) if such
reconciliation results in Tenants owing funds, Purchaser shall have the right to
collect such funds from the Tenants and Purchaser shall promptly pay to Seller a
portion of the funds so collected,



                                       27
<PAGE>


prorated for the portion of the year during which Seller owned the Property.

Purchaser, provided that where the improvement has been substantially completed
as of the Closing Date, such pending lien shall be considered certified.

    18. CLOSING COSTS. At the Closing, Seller shall pay the documentary
stamps and surtax, if any, due on the deed of conveyance. Purchaser shall pay
the owner's title insurance premium. Seller and Purchaser shall equally bear the

recording costs of any instruments received by that party, except that Seller
shall pay the recording costs on documents necessary to clear title.

gross negligence or willful malfeasance.

        23.4 If the parties (including Escrow Agent) shall be in disagreement
about the interpretation of this Agreement, or about their respective rights and
obligations, or about the


                                       32
<PAGE>


propriety of any action contemplated by Escrow Agent, Escrow Agent may, but

disagreement; upon filing such action, Escrow Agent shall be released from all
obligations under this Agreement. Escrow Agent shall be indemnified for all
costs and reasonable attorneys' fees, including those for appellate and post
judgment matters and for paralegals and similar persons, incurred in its
capacity as escrow agent in connection with any such interpleader action; Escrow
Agent may represent itself in any such interpleader action and charge its usual
and customary legal fees for such representation, and the court shall award such

Agent shall be fully protected in suspending all or part of its activities under
this Agreement until a final judgment in the interpleader action is received.

     25. RISK OF LOSS.

        25.1 The Property shall be conveyed to Purchaser in the same condition
as on the date of this Agreement, ordinary wear and tear excepted, free of all

approved by Purchaser in writing). Seller shall not remove anything from the
Property between the date of this Agreement and the Closing.

        25.2 Upon receipt of an offer or any notice or communication from any
governmental or quasi-governmental body seeking to take under its power of
eminent domain all or any portion of the Property, Seller shall promptly notify
Purchaser of the receipt of same and shall send such communication, or a copy of
it, to Purchaser. Upon receipt of such notice, Purchaser shall have the right to
rescind this Agreement by delivery of written notice to Seller within fifteen
(15) days of Purchaser's receipt of the communication from Seller. In the event
Purchaser elects to rescind, Escrow Agent, subject to the provisions of Section
11.3, shall return the Deposit, together with all interest earned thereon, to
Purchaser, and both parties shall be released from all further obligations under
this Agreement, except for those which expressly survive such termination. In
the event that Purchaser elects not to rescind, then Purchaser shall be entitled
to all condemnation awards and settlements. Seller and Purchaser agree to
cooperate with each other to obtain the highest and best price for the condemned
property.

shall be deferred for up to one hundred twenty (120) days to permit such repair
and restoration. If Seller is unable to repair and restore within such one
hundred twenty (120)-day period, then Purchaser shall have the option of (a)
terminating this Agreement by written notice to Seller, whereupon Escrow Agent,
subject to the provisions of Section 11.3, shall return the Deposit, together
with all interest earned thereon, to Purchaser, and both parties shall be
released from all further obligations under this Agreement, except those which
expressly survive such termination, or (b) proceeding with the Closing, in which
case Purchaser shall be entitled to all insurance proceeds (subject to the
