         4. TITLE AND SURVEY.

                  A. Title Report. As soon as it can be obtained with reasonable
diligence, but in no event later than the second business day after the
Effective Date of this Agreement, Seller shall obtain from Title Company, and
deliver to Buyer, a written



                                      -2-
   3

commitment (or commitments) binding Title Company to insure title to the Real
Property in Buyer by its A.L.T.A. Form B, Owner's Title Insurance Policy (the
"OWNER'S POLICY"), upon recording of the deed (or deeds) to be given by Seller
(the "TITLE COMMITMENT"), along with legible copies of all documents referred to
therein (the Title Commitment and all such documents herein referred to as the
"TITLE INFORMATION"). To the maximum extent Buyer is able based upon the Title
Information and the existing surveys of the Property which by then have been
made available to Buyer by Seller, but without the Surveys, Buyer shall give
Seller written notice on or before the expiration of fifteen (15) business days
after receipt of the Title Information and existing surveys that the condition
of title as set forth in such Title Information and existing surveys is or is
not satisfactory, in Buyer's sole discretion, such notice stating with
specificity any matters Buyer considers unsatisfactory. Buyer shall give Seller
written notice on or before the expiration of fifteen (15) business days after
receipt of the Title Information and the Surveys ("TITLE OBJECTION PERIOD") that
the condition of title as set forth in such Title Information and the Surveys is
or is not satisfactory, in Buyer's sole discretion, such notice stating with
specificity any matters Buyer considers unsatisfactory ("TITLE OBJECTION"), and
in the event Buyer states that the condition of title or Surveys is not
satisfactory, Seller shall have until the expiration of the Inspection Period,
at its option, to eliminate or modify all such Title Objections to the sole
satisfaction of Buyer. If Buyer does not notify Seller in writing of any Title
Objections within the Title Objection Period, or if Buyer does not terminate
this Agreement as herein provided on or before the end of the Inspection Period,
Buyer shall be conclusively presumed to have waived its objections to any
condition of title reflected in the Title Commitment and the Surveys. In no
event shall the provisions of Paragraphs 4.A. or 4.B. operate to extend or
postpone the Closing.

                  B. Surveys. On or before the second business day after the
Effective Date of this Agreement, Seller shall deliver to Buyer such existing
surveys of the Real Property as are within Seller's possession or control. As
soon as they can be obtained with reasonable diligence, Seller shall obtain and
deliver to Buyer current staked boundary and occupation (as-built) surveys of
the Real Property (the "SURVEYS") prepared by licensed Florida land surveyors in
accordance with the Florida Minimum Technical Standards for surveys as set forth
by the Florida Board of Professional Land Surveyors in Chapter 61G17-6 of the
Florida Administrative Code. Seller shall be responsible for and shall pay the
cost of said Surveys. In addition to other Title Objections raised by Buyer, if
the Surveys show an encroachment on the Real Property or that improvements
located on or intended to be located on the Real Property in fact encroach on
lands of others, or violate any applicable restrictions, covenants, or
governmental regulations, and if Buyer shall notify Seller of its objection to



                                      -3-
   4

said encroachments within the Title Objection Period, the same shall be treated
as a Title Objection.

         5. DUE DILIGENCE.

                  A. Due Diligence Investigations. Buyer shall have until 5:00
p.m. (C.S.T.) on the date which is forty (40) days after the Effective Date (the
"INSPECTION PERIOD") at its expense to perform such inspections and testing, and
to conduct such other studies, as Buyer deems necessary or advisable in order to
determine the feasibility of Buyer's purchase of the Property. Commencing on or
before the Effective Date, Buyer shall, at Buyer's sole expense, (i) commission
a comprehensive engineering study of the Property (including specifications of
all fireproofing) and an appropriate environmental survey and audit of the
Property, and (ii) commence a comprehensive legal and accounting review of the
Property and all leases and other documents pertinent thereto; and Buyer shall
exercise reasonable diligence to cause such studies to be diligently,
continuously and expeditiously prosecuted to completion. In the event Buyer
determines that the purchase of the Property by Buyer is not feasible, Buyer
shall so notify Seller in writing within said Inspection Period, whereupon the
Deposit shall be returned to Buyer and this Agreement shall be terminated. If
Buyer does not terminate this Agreement by written notice to Seller before the
expiration of the Inspection Period, as hereinabove provided, then Buyer shall
be conclusively presumed to have waived its right to terminate this Agreement as
provided in this paragraph 5. Buyer and its agents and representatives shall
have a non-exclusive right to enter upon the Property during the Inspection
Period for inspection, surveys, soil tests, hazardous substances/environmental
studies, engineering and feasibility studies, zoning, and land-use plan
analysis; provided that Buyer shall provide to Seller reasonable advance notice
of any activities of Buyer or any agent, representative or contractor of Buyer
on the Property, and further provided that Seller shall be afforded the
opportunity to have a representative of Seller accompany and observe the
activities of Buyer or any such agent, representative or contractor of Buyer on
the Property.

                  B. Documents to Buyer Before Closing. Prior to or as soon as
reasonably possible after the Effective Date of this Agreement, Seller shall
deliver to Buyer all of the items identified in Exhibit "C" attached hereto as
are in Seller's possession. Seller shall exercise diligent efforts to deliver to
Buyer originals or copies of all amendments or supplements to the items
identified on Exhibit "C" which come into Seller's possession.


                  C. Estoppel Certificates. Seller shall exercise diligent
efforts to obtain and deliver to Buyer, as soon as reasonably possible but in no
event later than the Closing Date, duly executed originals of a certificate
("ESTOPPEL CERTIFICATE")



                                      -4-
   5

in the form attached hereto as Exhibit "D" or in the form specified in the
respective leases, if any, or in such other form as Seller is able to obtain
said Estoppel Certificates as long as neither Buyer nor Buyer's lender has any
reasonable objection to such other form, executed by tenants leasing space in
the Property and by each of their respective Guarantors, if any. If prior to
Closing all of the Estoppel Certificates and consents have not been delivered to
Buyer in the required form, or in another form to which neither Buyer nor
Buyer's lender has any reasonable objection, Buyer may terminate this Agreement
pursuant to the provisions of paragraph 5.A. above.

                  D. Inspection of Books and Records. At reasonable times
following reasonable notice, Buyer, its accountants, architects, attorneys,
engineers, contractors and other representatives shall be afforded reasonable
access (1) to the Property to inspect, measure, appraise, test and make surveys
of the Property and (2) to all books, records and files relating to the
Property. Buyer shall have the right, at Buyer's expense, to make copies of all
such books and records, including, without limitation, all books and records
relating to increases in real estate taxes, building and operations maintenance
costs allocable to tenants and all information reasonably necessary for Buyer to
audit the income and expenses of the Property; provided, however, that Buyer
shall return all copies of such books and records if Closing does not occur
under this Agreement.

                  E. No Interference. During the pendency of this Agreement
neither Buyer nor its agents will unreasonably interfere with the activity of
tenants or persons providing service in the Property. Buyer shall cause its
agents, representatives, employees and contractors performing or conducting any
inspections, testing or other activities on the Property to conduct such
inspections, testing and other activities in such a manner as to minimize damage
to the Property and interference with the activities of Seller and Seller's
tenants and invitees on the Property. Buyer agrees to indemnify and defend
Seller against any and all cost, claim, loss, expense, liability or actual
damage Seller may incur or be subject to arising from or relating to any claim
of personal injury or property damage that may arise against the Property or the
Seller as a result of or in connection with the activities of Buyer or its
employees, agents, contractors or representatives, or any claims of lien filed
at any time relating to any work or activities performed by or for Buyer or any
employee, agent or contractor of Buyer on or relating to the Property. Buyer
shall promptly repair any damage to the Property caused by Buyer's agents,
representatives, employees or contractors and which results in an unsafe or
unlawful condition on the Property. Upon termination of this Agreement, Buyer
shall repair any damage to the Property caused by Buyer's agents,
representatives, employees or contractors promptly upon receipt of notice from
Seller specifying the repairs required. If Buyer fails to complete any repairs
Buyer is obligated to make



                                      -5-
   6

under this paragraph 5.E. within a reasonable time, Seller may, but shall not be
obligated to, make such repairs on Buyer's behalf, and if Seller makes such
repairs on Buyer's behalf, Buyer shall, within ten (10) days after demand
therefor, reimburse Seller for Seller's actual expenses incurred in completing
such repairs. Buyer's indemnification, duty to defend and hold harmless, and
duty to repair under this paragraph 5.E. shall survive Closing or termination of
this Agreement.

                  F. Due Diligence Information. Prior to entry upon the Property
by any agent or contractor engaged by Buyer to perform inspections,
investigations and/or testing, or otherwise to assist in Buyer's due diligence
investigation of the Property, Buyer shall notify Seller in writing of the name,
address, contact person, and scope of work such agent or contractor has been
engaged to perform; and Buyer hereby authorizes each such agent or contractor
(and upon Seller's request Buyer will confirm such authorization by written
notice to such agent or contractor, with a copy to Seller) to provide to Seller,
upon Seller's request, copies of any and all reports, studies, audits, or other
information developed or discovered by said contractor or agent, provided Seller
shall be responsible for payment to said contractor or agent of charges for
copying and delivery of and any other fees charged by said agent or contractor
in connection with providing to Seller copies of any such documents requested by
Seller.

                  G. Independent Audit. Promptly following the execution of this
Agreement, Seller shall provide to Buyer's representatives and independent
accounting firm access to all financial and other information relating to the
Property which would be sufficient to enable Buyer's representatives and
independent accounting firm to prepare audited financial statements for the
property for 1995, 1996 and 1997 year-to-date in conformity with generally
accepted accounting principles and to enable them to prepare such statements,
reports or disclosures as Buyer may deem necessary or advisable. Seller shall
reasonably cooperate with Buyer's representatives and independent accounting
firm in connection with the aforementioned financial analysis and shall provide
any additional information necessary to allow buyer to make disclosures required
by and otherwise comply with the financial accounting requirements of Regulation
S-X promulgated by the Securities and Exchange Commission. Seller shall provide
Buyer's independent accounting firm a signed representation letter which will be
sufficient to enable an independent public accountant to render an opinion on
the financial statements related to the Property. Seller shall authorize any
attorneys who have represented Seller in any material litigation pertaining to
or affecting the Property to respond, at Buyer's expense, to inquiries from
Buyer's representatives and independent accounting firm. If and to the extent
Seller's financial statements pertaining to the Property for



                                      -6-
   7

any periods during the years 1995, 1996 or 1997 year-to-date have been audited,
promptly after the execution of this Agreement, Seller shall provide Buyer with
copies of such audited financial statements and shall cooperate with Buyer's
representatives and independent public accountants to enable them to contact the
auditors who prepared such audited financial statements and to obtain, at
Buyer's expense, a reissuance of such audited financial statements. If this
Agreement terminates prior to the Closing, other than by reason of a default of
Seller, Buyer shall deliver to Seller copies of any audited financial statements
of the Property prepared for Buyer and assign to Seller without warranty all of
Buyer's right thereto.

         6. CLOSING. The closing of the sale and purchase herein provided
("CLOSING") shall be consummated at the offices of Escrow Agent in Tampa,
Florida, by delivery of the necessary funds and documents to Escrow Agent in
order to enable the Escrow Agent to close the transaction contemplated by this
Agreement on or before the date which is ten (10) days after the expiration of
the Inspection Period ("CLOSING DATE"). Notwithstanding the foregoing, Buyer
shall exercise its best efforts to close the transaction contemplated by this
Agreement on or before December 15, 1997. In the event the Closing is delayed
beyond December 15, 1997, and such delay is caused solely by the action or
inaction of Buyer, or solely by Buyer's failure to exercise its best efforts to
close on or before December 15, 1997, then the Purchase Price shall be increased
by $10,000.00 per day for each day after December 15, 1997, until and including
the day on which the Closing actually is completed.

                           (3) Additional Documents. In addition, each party
shall promptly execute and deliver to Escrow Agent such other documents as are
reasonably requested to effectuate the closing of the transaction contemplated
by this Agreement.

         The foregoing deliveries shall be made pursuant to this Agreement and

this Agreement or the recording of any instrument or document provided herein to

audits of the Property, including, but not limited to, the costs of any
environmental or financial audits. Seller shall pay (1) one-half of the cost of
escrow arrangements, (2) one-half of all applicable documentary stamp taxes or
other transfer taxes, if any, due in connection with the closing contemplated by
this Agreement or the recording of any instrument or document provided herein to

and expenses relating to any financing of the purchase of the Property by Buyer.
The cost of obtaining the Surveys shall be paid as provided in Paragraph 4.B.
hereof. Seller and Buyer shall each pay their respective (i) legal fees and
expenses and (ii) share of prorations (as provided below).

                  D. Prorations.

                           (1) Items to be Prorated. The following shall be
prorated between Seller and Buyer as of the Closing Date (with all income and
expenses for the Closing Date being allocated to Seller):

                                    (i) All real estate and personal property ad
valorem taxes on the Property for the current year. In the event the amount of
said ad valorem taxes for the year during which Closing occurs can not be
ascertained on the Closing Date, such taxes shall be prorated based upon the
amounts due for the year preceding the year during which Closing occurs, and
such proration of taxes shall be adjusted between Seller and Buyer after the tax
bills for the Property for the year during which Closing occurs are issued.

                                    (ii) All rentals and other tenant charges
collected on or before the Closing Date. All rentals due on or before the
Closing Date which are collected by Buyer or Seller after the Closing shall be
prorated as of the Closing Date as and when such rentals are collected.

                                    (iii) All operating expenses.

                           (2) Operating Costs Pass-throughs. Not later than
April 1, 1998, Buyer shall reconcile with tenants of the Property the amounts
paid or payable on account of operating expenses



                                      -9-
   10

incurred during calendar year 1997 and adjustments therefor due from or to
tenants of the Property on account thereof in accordance with the terms of the
Leases. Before Buyer delivers such reconciliation of operating costs
pass-throughs to tenants of the Property, Buyer shall deliver to Seller copies
of said proposed reconciliation statements for Seller's reasonable review and
approval. Within a reasonable time (or times) after such year-end reconciliation
of operating costs pass-throughs, Buyer and Seller agree to adjust between
themselves any amounts which may due from one of them to the other as a result
of the proration of amounts due to or from tenants in connection with the
reconciliation of operating costs pass-throughs under the Leases for calendar
year 1997. After Closing, Buyer shall exercise commercially reasonable efforts
to collect all sums due from tenants of the Property under the terms of the
Leases (including but not limited to amounts due in connection with
reconciliation of operating costs pass-throughs) relating to periods prior to
Closing, and Buyer shall deliver to Seller such amounts as are due relating to
periods prior to Closing within a reasonable time after Buyer's receipt thereof;
provided, however, that amounts collected by Buyer from tenants owing rents
which as of the Closing Date are delinquent ("DELINQUENT RENTS") shall be
applied to the amounts of rents owed by such tenant which are not Delinquent
Rents, in the order such non-Delinquent Rents became due, and then to Delinquent
Rents. The provisions of this paragraph 6.D. shall survive Closing.

                           (3) Security Deposits. Security deposits under Tenant
Leases (if and to the extent that such deposits are in Seller's actual
possession and have not been lawfully applied by Seller to any other obligations
of any lessee under the Tenant Leases) shall be credited against the Purchase
Price at Closing. With respect to any such security deposits credited against
the Purchase Price, Buyer agrees to hold and disburse said security deposits in
compliance with the provisions of applicable leases and all applicable laws.
After Closing, Buyer shall indemnify Seller from and against any and all claims
and liabilities arising from or relating to any such security deposits credited
to Buyer at or after Closing.

                           (4) Calculation. The prorations and payments shall be
made on the basis of a written statement submitted to Buyer by Seller not less
than two (2) business days prior to Closing and approved by Buyer and Seller. In
the event any prorations or apportionments made under this subparagraph D shall
prove to be incorrect for any reason (even if previously approved by Buyer
and/or Seller), then any party shall be entitled to an adjustment to correct the
same upon written request to the other party on or before December 31, 1998. Any
item which cannot be finally prorated because of the unavailability of
information shall be tentatively prorated on the basis of the best data then
available and reprorated when the information is available.



                                      -10-

         7. DESTRUCTION/CONDEMNATION OF PROPERTY. In the event any of the Real
Property is damaged or destroyed by any casualty or by a partial taking or
condemnation under the provisions of applicable eminent domain law after the
Effective Date hereof but prior to the Closing Date, Seller shall have no
obligation to repair or replace any such damage or destruction. In the event of
any such damage or destruction to any portion of the Real Property by any
casualty which casualty damage or destruction would cost more than the
"Materiality Threshold" (as hereinafter defined) to repair, or in the event of a
material partial taking which causes a reduction in the value of the Real
Property by more than the Materiality Threshold, Seller may, by written notice
to Seller, terminate this Agreement. If Buyer elects not to terminate this
Agreement, or if Buyer has no right to terminate this Agreement, then upon
consummation of the transaction herein provided, Seller shall (i) assign to
Buyer all claims of Seller under or pursuant to any applicable casualty
insurance coverage or under the provisions applicable eminent domain law

the right to cure such condition before the Closing, and the existence of such
condition shall not be grounds for Buyer to terminate this Agreement, provided
that (i) Seller, promptly after discovering the condition, covenants with Buyer
in writing that Seller will cure such condition prior to Closing, and (ii)

actual damages, including reasonable attorneys' fees, which Buyer or Buyer's
Permitted Assignee may incur because of any breach of any of the
representations, warranties or covenants of Seller herein contained, whether
prior to or after the Closing; provided, that if a claim for any such breach is
not asserted within one (1) year after the Closing Date, it shall be deemed
waived. Notwithstanding the foregoing, if Buyer or Buyer's Permitted Assignee
has actual knowledge of any such breach prior to Closing and nonetheless
proceeds with the Closing, then in such event any such breach shall be deemed
waived by Buyer and Buyer's Permitted Assignee.



                                      -16-
   17

                  B. Indemnity for Breach by Buyer. Subject to the other
provisions hereof, Buyer shall indemnify Seller, its successors and assigns,
against, and shall hold Seller, its successors and assigns, harmless from, any
costs, expenses, or actual damages, including reasonable attorneys' fees, which
Seller may incur because of any breach of the representations, warranties or
covenants of Buyer herein contained, whether prior to or after the Closing;
provided, that if a claim for any such breach is not asserted within one (1)
year after the Closing Date, it shall be deemed waived. Notwithstanding the
foregoing, if Seller has actual knowledge of any such breach prior to Closing
and nonetheless proceeds with the Closing, then in such event any such breach
shall be deemed waived by Seller.

         10. DISPOSITION OF DEPOSIT. If the transaction herein provided shall
not be closed by reason of Seller's default under this Agreement or the failure
of satisfaction of the conditions described in paragraph 11.B. hereof, and Buyer
shall not have defaulted under this Agreement, then upon Buyer's demand, Escrow
Agent shall return to Buyer the Deposit after providing notice to Seller, and in
the event of conflicting instructions from Seller, Escrow Agent shall interplead
the Deposit. Upon Buyer's receipt of the Deposit, neither party shall have any
further obligation or liability to the other; except that if the transaction
shall not be closed by reason of Seller's default under this Agreement, Buyer's
sole remedies for any such default shall be either (i) to terminate this
Agreement and receive a return of the Deposit, or (ii) to seek specific
performance of this Agreement; and this shall be Buyer's sole remedy for
Seller's default hereunder. In the event the transaction herein provided shall
not close for any reason other than the failure of satisfaction of the
conditions described in paragraph 11.B. hereof or the default of Seller, then
Escrow Agent shall deliver the Deposit to Seller as full compensation and
liquidated damages under and in connection with this Agreement after providing
notice to Buyer, and in the event of conflicting instructions from Buyer, Escrow
Agent shall interplead the Deposit. In the event the transaction herein provided
shall close, Escrow Agent shall apply the Deposit as a partial payment of the
Purchase Price, or return the Deposit to Buyer, at Buyer's option. In connection
with the foregoing, the parties recognize that Seller will incur expenses in
connection with the transaction contemplated by this Agreement and that the
property will be removed from the market; further, that it is extremely
difficult and impracticable to ascertain the extent of detriment to Seller
caused by the breach by Buyer under this Agreement and the failure of the
consummation of the transaction contemplated by this Agreement or the amount of
compensation Seller should receive as a result of Buyer's breach or default; and
Buyer and Seller agree that the amount of the Deposit is a reasonable estimate
of Seller's damages in the event of Buyer's breach or default and that such
amount will not constitute a penalty or forfeiture in the event the Deposit is
disbursed to Seller upon Buyer's breach or default hereof.

mutually agree to the disbursement thereof, or until a judgment of a court of
competent jurisdiction shall determine the rights of the parties thereto, or
Escrow Agent may deposit or interplead all monies then held pursuant to this
Agreement with the Clerk of the Circuit Court for Hillsborough County, Florida,
at its option, without further liability or responsibility on its part. Upon
notifying Buyer and Seller of such course of action, all liability on the part
of Escrow Agent shall fully terminate. In the event of any suit between Buyer
and Seller wherein Escrow Agent is made a party by virtue of acting as such
Escrow Agent hereunder, or in the event of any suit wherein Escrow Agent
interpleads the subject matter of this escrow, Escrow Agent shall be entitled to
recover reasonable attorney's fees and costs incurred by Escrow Agent, said fees
and costs to be charged and assessed as court costs in favor of the prevailing
party.

                           Escrow Agent joins in the execution of this
Agreement for the sole purpose of agreeing to be bound by the provisions set
forth in this Agreement with respect to the investment, disbursement and
delivery of the Deposit. Buyer and Seller hereby authorize the investment,
payment and delivery of the Deposit by the Escrow Agent in accordance with the
terms and provisions set forth in this Agreement. If required by Escrow Agent,
Buyer and Seller agree to enter into Escrow Agent's normal form of escrow
agreement, subject to such reasonable modifications requested by Buyer and
Seller as are acceptable to Escrow Agent. Buyer shall be responsible for any
reasonable escrow charges of Escrow Agent.

         15. MISCELLANEOUS.

                  A. Brokers. Seller represents and warrants to Buyer, and Buyer
represents and warrants to Seller, that no broker or finder other than Ryon &
Associates ("Broker") has been engaged by it, respectively, in connection with
any of the transactions contemplated by this Agreement or to its knowledge is in
any way connected with any of such transactions. In the event of a claim by any
broker, finder or other party other than Broker for broker's or finder's fee or
commissions in connection herewith, then Seller shall indemnify, protect, defend
and hold Buyer harmless from and against the same if it shall be based upon any
statement, action or agreement alleged to have been made by Seller, and Buyer
shall indemnify, protect, defend and hold Seller harmless from and against the
same if it shall be based upon any statement, action or agreement alleged to
have been made by Buyer. The parties' respective indemnification obligations
under this paragraph shall survive the Closing of the transaction contemplated
hereunder or the earlier termination of this Agreement. Seller agrees to pay a



                                      -22-
   23

commission to Broker at Closing pursuant to a separate written agreement between
Seller and Broker.

                  B. Limitation of Liability. No present or future partner,
director, officer, shareholder, employee, advisor or agent of or in Seller shall
have any personal liability, directly or indirectly, under or in connection with
this Agreement or any agreement made or entered into under or in connection with
the provisions of this Agreement, or any amendment or amendments to any of the
foregoing made at any time or times, heretofore or hereafter, and Buyer and its
successors and assigns and, without limitation, all other persons and entities,
shall look solely to Seller's assets for the payment of any claim or for any
performance, and Buyer hereby waives any and all such personal liability. No
present or future partner, director, officer, shareholder, employee, advisor or
agent of or in Buyer shall have any personal liability, directly or indirectly,
under or in connection with this Agreement or any agreement made or entered into
under or in connection with the provisions of this Agreement, or any amendment
or amendments to any of the foregoing made at any time or times, heretofore or
hereafter, and Seller and its successors and assigns and, without limitation,
all other persons and entities, shall look solely to Buyer's assets for the
payment of any claim or for any performance, and Seller hereby waives any and
all such personal liability. The limitations of liability contained in this
paragraph are in addition to, and not in limitation of, any limitation on
liability applicable to Seller and Buyer provided in this Agreement or by law or
by any other contract, agreement or instrument.

                  C. Successors and Assigns. Buyer may not assign or transfer
its rights or obligations under this Agreement without the prior written consent
of Seller (in which event such transferee shall assume in writing all of the
transferor's obligations hereunder, but such transferor shall not be released
from its obligations hereunder); provided, however, that Seller shall not
unreasonably withhold such consent. No consent given by Seller to any transfer
or assignment of Buyer's rights or obligations hereunder shall be construed as a
consent to any other transfer or assignment of Buyer's rights or obligations
hereunder. No transfer or assignment in violation of the provisions hereof shall
be valid or enforceable. Subject to the foregoing, this Agreement and the terms
and provisions hereof shall inure to the benefit of and be binding upon the
successors and assigns of the parties.

generally recognized overnight carrier regularly providing proof of delivery),

                           (1) Incorporation of Exhibits. All exhibits attached

forth in (and shall be deemed to be a part of) this Agreement.

supersedes all prior agreements between the parties hereto respecting such

                           (5) Severability. If any term or provision of this
Agreement or the application thereof to any person or circumstance shall, to any
extent, be invalid or unenforceable, the remainder of this Agreement, or the
application of such term or provision to persons or circumstances other than
those as to which it is held invalid or unenforceable, shall not be affected
thereby, and each such term and provision of this Agreement shall be valid and
be enforced to the fullest extent permitted by law.

                           (6) Captions. The captions and paragraph headings in

define, describe or limit the scope or intent of this Agreement or any of the
provisions hereof.


                           (7) Cumulative Remedies. No remedy conferred upon a
party in this Agreement is intended to be exclusive of any other remedy herein
or by law provided or permitted, but each shall be cumulative and shall be in
addition to every other remedy given hereunder or now or hereafter existing at
law, in equity or by statute (except as otherwise expressly herein provided).

                           (8) No Waiver. No waiver by a party of any breach of
this Agreement or of any warranty or representation hereunder by the other party
shall be deemed to be a waiver of any other breach by such other party (whether
preceding or succeeding and whether or not of the same or similar nature), and
no acceptance of payment or performance by a party after any breach by the other
party shall be deemed to be a waiver of any breach of this Agreement or of any
representation or warranty hereunder by such other party, whether or not the
first party knows of such breach at the time it accepts such payment or
performance. No failure or delay by a party to exercise any right it may have by
reason of the default of the other party shall operate as a waiver of default or
modification of this Agreement or shall prevent the exercise of any right by the
first party while the other party continues to be so in default.

                           (9) Consents and Approvals. Except as otherwise
expressly provided herein, any approval or consent provided to be given by a
party hereunder may be given or withheld in the absolute discretion of such
party.

Agreement, expressed or implied, is intended to confer any rights or remedies
upon any person, other than the parties hereto and, subject to the restrictions
on assignment herein contained, their respective successors and assigns.

written agreement of amendment executed by all parties, but not otherwise.

                           (13) Survival of Representations. Except as otherwise
expressly provided in this Agreement, the representations and warranties herein
shall not survive Closing or termination of this Agreement. The express
representations and warranties of Buyer and Seller contained in this Agreement
and in the Warranty Documents shall survive for one year after Closing.

                           (14) Joint Preparation. Both parties to this
Agreement having participated fully and equally in the negotiation and
preparation hereof, this Agreement shall not be more strictly construed, or any
ambiguities within this Agreement resolved, against either party hereto.

                  J. Counterparts. This Agreement may be executed in any number
of counterparts, provided each of the parties hereto executes at least one
counterpart; each such counterpart hereof shall be deemed to be an original
instrument, but all such counterparts together shall constitute but one
agreement. This Agreement shall be deemed to have been duly executed and
