         contemplated by this Agreement has been or will have been duly taken
         prior to the Closing. This Agreement constitutes the valid and binding
         obligation of Seller and is enforceable against Seller in accordance
         with its terms, except if such enforcement may be affected by
         bankruptcy, moratorium or laws relating to creditor's rights or general
         principles of equity.

              B. Consents; No Breach. No consent, approval or authorization of,
         or designation, declaration or filing with, any governmental authority
         on the part of Seller is required in connection with the valid

         performance of this Agreement and the consummation of the transactions
         contemplated hereby will not: (i) violate any provision of the organic
         documents of Seller; (ii) violate, conflict with or result in the

         to which Seller is a party; (iii) violate any order, judgment,

         jurisdiction applicable to the transactions contemplated herein.

              C. No Commitments, Defaults or Litigation. None of the Property is
         bound or affected by any: (i) mortgage, deed of trust, loan or other
         security agreement that will not be satisfied at Closing or, with
         respect to the Real Property subject to Ground Leases, the subject of a
         Non-Disturbance Agreement obtained by Seller from the lessor's lender;
         (ii) contract to purchase or sell; (iii) noncompetition covenant; (iv)
         option or right of first refusal; (v) any prohibition or restriction
         that prevents the subleasing of any of the Sites or requires the
         consent of any third party in connection with the subleasing of any of
         the Sites; or (vi) any other agreement or commitment outside the
         ordinary course of business or material to the ownership and operation
         of the Sites or the Facilities, or any oral agreements (all of the
         foregoing collectively referred to hereinafter as the "COMMITMENTS").
         True and complete copies of the Ground Leases, the Tower Leases,
         Intangibles and the Permits, as amended, if applicable, that are
         evidenced by written documents, have been delivered to Purchaser. There
         are no existing material defaults, events of default or events,
         occurrences, or acts that, with the giving of notice or lapse of

                                       5

         time or both, would constitute defaults, and no penalties have been
         incurred, with respect to any of the Ground Leases, the Tower Leases,
         the Permits or any other contractual obligation; except as disclosed to
         Purchaser in writing, none of the foregoing documents require the
         consent of any third party to the transactions contemplated hereby.
         Seller has not received any rents or other amounts due Seller under the
         Tower Leases in respect of any period exceeding thirty (30) days from
         the date hereof. All tenants under the Tower Leases have installed
         their respective equipment at the Facilities, and, to the Seller's
         knowledge, no such tenant intends to exercise any right of termination
         set forth in the Tower Leases. Seller has no knowledge of any claim,
         litigation or proceedings affecting the Facilities or the Property that
         have not been disclosed to Purchaser in writing.

              D. No Violation; Restrictions. Neither the execution and
         performance of this Agreement or the agreements contemplated hereby,
         nor the consummation of the transaction contemplated hereby or
         applicable to the Property thereby will violate Applicable Law or any
         term of any Permit or give any party the right to revoke any Permit.
         Seller has complied in all material respects with all Applicable Law
         where the failure to comply is reasonably expected to result in a
         liability of Purchaser or affect the Property or the operation of the
         Facilities. The Permits constitute all licenses, franchises, permits,
         zoning variances, and other authorizations necessary to construct and
         operate the Facilities in compliance with Applicable Law and are in
         full force and effect.

              E. Commissions. Seller has not incurred any obligation for any
         real estate commission, finder's, broker's, or agent's fee in
         connection with the transaction contemplated hereby.

              F. Financial. The Tower Leases and the Ground Leases are valid and
         enforceable, except as such enforcement may be affected by bankruptcy,
         moratorium or other laws relating to creditor's rights generally or
         general principles of equity, and constitute the entirety of the
         agreement between Seller and the respective parties thereto, and there
         are no unwritten agreements, indirect or undisclosed payments or other
         consideration due or which shall become due to the parties to such
         agreements except as expressly set forth in the written terms thereof.
         Exhibit "B" accurately sets forth, for each Tower Lease, the tenant
         name, Site name, contracted rental amount, escalator, frequency of
         escalator and number of tenant renewal options. The tower income
         calculation set forth on Exhibit "E" attached hereto is true and
         correct in all material respects. To Seller's current actual knowledge
         there are no adverse costs, expenses, liabilities or claims related to
         the Facilities that could reasonably be expected to have a material
         adverse affect on the net operating income from the Facilities that has
         not been disclosed in writing. The information, reports, financial
         statements, exhibits and schedules furnished in writing by or on behalf
         of the Seller to Purchaser hereof, to Seller's actual knowledge after
         having made due inquiry, do not contain any untrue statement of
         material fact or omit to state any material fact necessary to make the
         statements herein or therein, in light of the circumstances under which
         they were made, not misleading. All written information furnished after
         the date hereof by or on behalf of the Seller to Purchaser in
         connection with this Agreement and the transaction contemplated hereby
         will, to Seller's actual knowledge after having made due inquiry, be
         true, complete and accurate in every material respect, or (in the case
         of projections) based on reasonable estimates, on the date as of which
         such information is stated. There is

                                       6

         currently no fact actually known to Seller that could reasonably be
         expected to have a material adverse effect on the Property or its
         operations, that has not been disclosed herein, or in a report,
         financial statement, exhibit, schedule, disclosure letter or other
         writing furnished to Purchaser for use in connection with the
         transaction contemplated hereby.

              respect to any violations of environmental laws applicable to the
              Property, and Seller is not aware of any fact or condition related
              to the ownership and operation of the Property that could
              reasonably be expected to lead to any environmental liability of
              Seller or Purchaser. Seller has complied with all environmental,
              health, and safety laws, and Seller is not aware of any action,
              suit, proceeding, hearing, investigation, charge, complaint,
              claim, demand, or notice which has been filed or commenced against
              it alleging any failure to so comply. Without limiting the
              generality of the preceding sentence, Seller has obtained and been
              in material compliance with all of the terms and conditions of all
              permits, licenses, and other authorizations that are required
              under, and has materially complied with all other limitations,
              restrictions, conditions, standards, prohibitions, requirements,
              obligations, schedules, and timetables that are contained in, all

              any prior owner or user of the Real Property, and there has been
              no release of, or contamination by, Hazardous Materials on the
              Real Property; and

              studies, NEPA reports, records and reports in its possession or
              control with respect to Property and all correspondence with any
              governmental entities concerning environmental or historical
              conditions of the Real Property, or which identify underground
              storage tanks or otherwise relate to contamination of the soil or
              groundwater of the Real Property or effluent into the air. As used
              herein, "HAZARDOUS MATERIALS" means any substance designated as
              being such under any Applicable Law.

              H. Real Estate Matters.

                   (a) Seller has good and marketable leasehold title to the
              Real Property and has peaceful possession of the Real Property it
              leases, and there are no outstanding liens or taxes currently due
              on the Real Property. Seller has fully paid and satisfied any and
              all amounts due to parties in providing services or materials with
              respect to the acquisition, construction and development of the

                                       7

              Sites, and no such party has the choate or inchoate right to
              record a lien or other such encumbrance against the Real Property.
              For the five (5) years preceding the date hereof, or for as long
              as Seller has leased the Real Property, Seller has filed all
              required tax returns and paid all taxes due and owing with respect
              to the Real Property.

                   (b) The Real Property, communication tower and all buildings,
              improvements, machinery, tower lighting, equipment, and other
              tangible assets owned by Seller and necessary for the operation of
              the Facilities, as presently conducted, are in compliance with all
              Applicable Laws, and the personal property described on Schedule
              1.0 hereof constitutes all of the personal property necessary for
              the use and operation of the Facilities as required by the Tower
              Leases. There are no outstanding NOTAM's with respect to the
              Facilities which have not been properly closed as required by
              Applicable Law.

                   (c) The communication towers and all buildings, improvements,
              machinery, equipment relating to the use and operation of the Real
              Property as a communications tower site, including without
              limitation, any climate control, lighting system, electrical
              system and other building equipment, owned by Seller have been
              maintained in accordance with customary industry practice, are in
              good operating condition and repair, reasonable wear and tear,
              resulting from ordinary usage excluded, and are suitable for the
              purposes for which they are presently used. To Seller's actual
              knowledge after due inquiry, there are no structural or latent
              defects in the aforesaid communication towers, equipment and
              improvements.

                   (d) Seller has not received notice of, or been served with,
              any pending or threatened litigation, claim, condemnation, or sale
              in lieu thereof with respect to any portion of the Real Property
              relating to or arising out of the ownership of the Real Property
              by any governmental instrumentality.

                   (e) To the knowledge of Seller, there is no proposed material
              increase in real property taxes payable on the Property. To the
              knowledge of Seller, no exemption from full taxation of any
              portion of the Real Property has been claimed in the previous five
              (5) years, and the Real Property is not subject to any rollback
              taxes. To the knowledge of Seller there are no material pending or
              proposed assessments for public improvements, or contemplated
              improvements that may lead to an assessment. Any personal and/or
              property tax information provided to Purchaser by Seller is true
              and correct in all material respects.

                   (f) Each parcel of Real Property abuts on and has direct
              vehicular access to a public road, or has access to a public road
              via a permanent, irrevocable, appurtenant easement benefiting the
              Real Property, and Seller has no knowledge of any fact or
              condition that could result in the termination or reduction of the
              current access from the Real Property to existing highways and
              roads, or to sewer or other utility services serving the Real
              Property. All utilities required for the operation of the
              Facilities, enter the Real Property through adjoining public
              streets, or, if they pass through an adjoining private tract, do
              so in accordance with valid easements.

                                       8

                   (g) No third party has any interest in or has received an
              assignment of the Tower Leases or any portion of the rents due
              thereunder.

              I. No Additional Representations. Seller is not making any
         representations or warranty, express or implied, of any nature
         whatsoever, except for the representations and warranties in this
         Section 6.

         7. Representation and Warranties of Purchaser. Purchaser represents and
warrants the following to Seller as of the Effective Date, which representations
and warranties shall be true and correct as of the Closing Date.

              A. Organization; Power and Authority; Authorization and Validity.
         Purchaser has full power and authority to execute, deliver, and perform
         its obligations under this Agreement and all other agreements and
         documents Purchaser is or will be executing in connection with the
         transaction contemplated hereby. All limited liability company action
         necessary on the part of Purchaser to authorize the execution and
         delivery to Seller of this Agreement and the performance and
         satisfaction of the obligations of Purchaser in connection with the
         transaction contemplated by this Agreement has been or will have been
         duly taken prior to the Closing. This Agreement constitutes the valid
         and binding obligation of Purchaser and is enforceable against
         Purchaser in accordance with its terms, except if such enforcement may
         be affected by bankruptcy, moratorium or laws relating to creditor's
         rights or general principles of equity.

              B. Consents; No Breach. No consent, approval or authorization of,
         or designation, declaration or filing with, any governmental authority
         on the part of Purchaser is required in connection with the valid
         execution and delivery of this Agreement. The execution, delivery and
         performance of this Agreement and the consummation of the transaction
         contemplated hereby will not: (i) violate any provision of the organic
         documents of Purchaser; (ii) violate, conflict with or result in the
         breach of any of the material terms of, result in a material
         modification of, otherwise give any other contracting party the right
         to terminate, or constitute (or with notice or lapse of time or both
         constitute) a default under, any material contract or other agreement
         to which Purchaser is a party; (iii) violate any order, judgment,
         injunction, award or decree of any court, arbitrator or governmental or
         regulatory body against, or binding upon, Purchaser or any Affiliate of
         Purchaser; or (iv) violate any statute, law or regulation of any
         jurisdiction applicable to the transaction contemplated herein.

              C. Commissions. Purchaser has not incurred any obligations for any
         real estate commission, finder's, broker's or agent's fee in connection
         with the transaction contemplated hereby.

              D. Information. Prior to Closing, Purchaser will be given access
         to information concerning the condition, properties, operations and
         prospects of the Property and Sites. Purchaser shall have the
         opportunity to ask questions of and to receive information from Seller
         and persons acting on its behalf concerning the Property, Sites and the
         operation of Seller's business. Purchaser acknowledges that prior to
         Closing, it shall undertake an independent investigation and
         verification of the Property and the ownership and operation of
         Seller's communication towers.

                                       9

              E. Financial Ability of Purchaser. Subject to the applicable terms
         of the credit facility, Purchaser has sufficient funds under its line
         of credit to consummate the transactions contemplated by this Agreement
         and Purchaser shall use commercially reasonable efforts to obtain
         financing of the transaction contemplated hereby from its lender.

              F. No Additional Representations. Purchaser is not making any
         representations or warranty, express or implied, of any nature
         whatsoever, except for the representations and warranties in this
         Section 7.

         8. Management of Facilities Before Closing Date. During the period
pending the Closing, except as otherwise permitted or required by this
Agreement, Seller shall (i) conduct the operations of the Facilities in the
ordinary and usual course of business consistent with past and current
practices; and shall not make any material changes to the Property or its
operation without obtaining the prior written consent of Purchaser; (ii) notify
Purchaser of material changes or adverse conditions with respect to the
operation of the Property; (iii) maintain casualty and liability insurance
amounts and coverages as required by the Commitments, Ground Leases and Tower
Lease; (iv) not enter into any leases or licenses of the Sites without the prior
written approval of the Purchaser; (v) not solicit or authorize any person to
solicit, or encourage, any inquiry or proposal for the sale of financing of all
or any material part of the Property or enter into negotiations for any such
proposal; (vii) use its best reasonable efforts to obtain such ground lease
estoppels and nondisturbance agreements as reasonably required by Purchaser or
its Lender; and (vii) remedy, at the sole expense of Seller, all liens, claims
or impairments to the marketability of title to the Real Property that would
have a material adverse impact on the use of the Property as a communication
tower site; (viii) not enter into any Commitment or transaction that could
reasonably be expected to materially or adversely affect the Facilities or the
Property.

         9. Noncompetition; Rights of First Refusal. Seller and its undersigned
principals, who joins in this Agreement intending to be bound by the terms of
this Section, covenant and agree that the proprietary information Seller and its
undersigned principal have acquired regarding the Facilities will enable Seller
and its undersigned principal to injure Purchaser and diminish the value of the
investment in the Property by Purchaser if Seller or its undersigned principal
should compete with Purchaser. Therefore, Seller and its undersigned principal
hereby agree that, without the prior written consent of Purchaser, neither
Seller nor its undersigned principal, shall for two (2) years from the Closing
Date, directly or indirectly, as a director, officer, agent, employee,
consultant or independent contractor or in any other capacity, (a) invest (other
than investments in publicly owned companies which constitute not more than ten
(10%) percent of the voting securities of any such company) or engage in any
business or activity that competes with the Facilities within a two (2) mile
radius of the Real Property (the "TERRITORY"); (b) contact, solicit or attempt
to solicit or accept business from any tenants of the Facilities for the purpose
of, or having the effect of, causing such tenants to terminate their business
relationship with Purchaser with respect to the Facilities after Closing; or (c)
or operate a communications tower facility within the Territory that competes
with the Facility.

         10. Inspection by Purchaser. During the Inspection Period Seller shall
permit Purchaser and its authorized representatives reasonable access to, and
make available for inspection, all of the Property and the business premises of
Seller and its employees, and furnish Purchaser all books, records, documents,
corresponding engineering and environmental reports,

                                       10

contracts, property and sale tax records, Commitments and information with
respect to the Property and the affairs of Seller. Seller shall (i) provide to
Purchaser financial statements and information related to the Property that is
kept or that should be kept in the ordinary course of Seller's business as is
required by Purchaser's lender so long as the documented third party
out-of-pocket administrative costs incurred by Seller in connection with such
delivery are at Purchaser's sole cost and expense, and (ii) cooperate with
Purchaser to provide to Purchaser's lender other financial statements and
information as is required by Purchaser's lender so long as such other financial
statements and information are generated by or on behalf of Purchaser at
Purchaser's sole cost and expense. Further, Purchaser shall have the right to
contact all tenants and prospective tenants under Tower Leases, the lessor under
the Ground Lease and such other parties as Purchaser reasonably determines in
connection with the inspection of the Property. Following the Closing Date,
Purchaser may be required to conduct audits of its business and any business it
has acquired in connection with additional financing of Purchaser, and Seller
agrees to cooperate with Purchaser in any such post-closing audits, as
reasonably requested by Purchaser, at Purchaser's sole cost and expense.

         11. Conditions Precedent of Purchaser. Notwithstanding any provision to
the contrary set forth herein, and except as may be waived in writing by
Purchaser, the obligations of Purchaser hereunder are subject to the fulfillment
at or before the Closing of each of the following conditions, and Purchaser
shall have the right to terminate this Agreement in its entirety, at Purchaser's
option, in the event all of the following conditions are not satisfied on or
before the Closing Date: (i) Purchaser has verified to its reasonable
satisfaction that each representation and warranty of Seller contained herein is
true and correct in all material respects and shall be true and correct in all
material respects as of the Closing; (ii) Seller shall have performed and
complied with all covenants or conditions required by this Agreement to be
performed and complied with by Seller at or before the Closing, including,
without limitation, delivery of all documents and items described in Section
5.B; (iii) Purchaser's receipt and approval of all Permits; (iv) no facts,
conditions or circumstances have arisen which could reasonably result in a
material adverse affect on the use and operation of the Facilities; (v)
Purchaser's receipt and approval of a Phase I Environmental Assessment and NEPA
report as to each Site; and (vi) Purchaser shall have received an ALTA Owner's
Title Insurance Policy insuring title to the Real Property, in form and
substance reasonably satisfactory to Purchaser and its lender.

         12. Casualty; Condemnation. In the event of casualty damage or
condemnation (or notice thereof) of a material portion of any Site occurs prior
to Closing, Purchaser shall have the right to (i) either terminate this
Agreement in its entirety; or (ii) proceed to Closing, in which event Seller
shall assign to Purchaser any insurance proceeds or damages received by Seller
with respect to such casualty or condemnation and/or any rights to recover same.

         13. Confidentiality. Without the prior written consent of Purchaser,
Seller will not disclose, and will not permit its representatives to disclose,
to any person other than its officers, directors and advisors (i) the fact that
discussions or negotiations are taking place concerning the transaction
contemplated hereby, or (ii) any of the terms, conditions or other facts with
respect to the transaction, including the status thereof, except to the extent
that Seller has, prior to any such disclosure, determined in good faith, after
consultation with counsel, that such disclosure is required by Applicable Law.

                                       11

         14. Indemnity by Seller. From and after the Closing Date, each of
Seller and its undersigned principal hereby agrees to indemnify, defend, and
hold harmless Purchaser and its officers, directors, shareholders, agents, and
attorneys for, from, and against all damages, claims, loss, costs (including
attorneys fees) asserted against or incurred by any of them by reason of, or
resulting from: (i) any breach by Seller of any representation, warranty, or
covenant contained herein or in any agreement executed pursuant hereto; (ii) all
liabilities of Seller not expressly assumed by Purchaser pursuant to the terms
hereof; (iii) the construction, operation and ownership of the Property through
the Closing Date (collectively, "DAMAGES"). Without limiting the generality of
the foregoing, the indemnification provided by this paragraph shall specifically
cover capital, operating, and maintenance costs, incurred in connection with any
investigation or monitoring of site conditions, any clean-up, containment,
remedial, removal, or restoration work required or performed by any federal,
state, or local governmental agency or political subdivision or performed by any
nongovernmental entity or person because of the presence, suspected presence,
release, or suspected release of any Hazardous Material in or into the air,
soil, groundwater, or surface water at, on, about, under, or within the Real
Property. Notwithstanding the foregoing, Seller's liability shall be limited to
the amounts paid to Seller hereunder.

         15. Indemnity by Purchaser. From and after the Closing Date Purchaser
shall indemnify, defend and hold harmless Seller and its officers, directors,
shareholders, agents, and attorneys for, from, and against all Losses asserted
against or incurred by any of them by reason of, or resulting from the failure
of Purchaser to comply with (i) any covenants or other commitments made by
Purchaser in this Agreement, (ii) such covenants and commitments set forth in
the Ground Leases and Tenant Leases that are expressly assumed by Purchaser,
provided that such Losses result from matters arising after the Closing Date.

         15.1 Indemnity Procedures. Promptly after receipt by an indemnified
party under Sections 14 and 15 of notice of the commencement of any action for
which indemnification may be available under Section 14 or 15, such indemnified
party shall, if a claim in respect thereof is to be made against an indemnifying
party under such Section, give notice to the indemnifying party of the
commencement thereof, but the failure so to notify that indemnifying party shall
not relieve it of any liability that it may have to any indemnified party,
except to the extent the indemnifying party demonstrates that the defense of
such action is prejudiced thereby. In case any such action shall be brought
against an indemnified party and it shall give notice to the indemnifying party
of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall elect, to assume the
defense thereof with counsel of its choice and, after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under such Section for any fees of other counsel or any other expenses, in
each case incurred by such indemnified party in connection with the defense
thereof. If an indemnifying party assumes the defense of such an action, (a) no
compromise or settlement thereof may be effected by the indemnifying party
without the indemnified party's consent (which shall not be unreasonably
withheld, delayed or conditioned) unless (i) there is no finding or admission or
any violation of law or any violation of the rights of any person and no effect
on any other claims that may be made against the indemnified party and (ii) the
sole relief provided is monetary damages that are paid in full by the
indemnifying

                                       12

party and (b) the indemnifying party shall have no liability with respect to any
compromise or settlement thereof effected without its consent (which shall not
be unreasonably withheld).

         16. Remedies. If Seller fails to comply with this Agreement for any
reason other than Purchaser's failure to perform its obligations under this
Agreement, Purchaser shall be entitled to, subject to the remainder of this
Paragraph 16, either (i) enforce specific performance of Seller's obligations
hereunder or (ii) terminate this Agreement, and recover any damages incurred by
Purchaser. Seller acknowledges that a breach of the terms hereof by Seller, or
refusal by Seller to consummate the transaction contemplated hereby will cause
irrevocable harm to Purchaser, for which there may be no adequate remedy at law
and for which the ascertainment of damages would be difficult. For this reason,
Seller has agreed that in the event of a default by Seller, Purchaser shall be
entitled to specific performance or injunctive relief in addition to other
remedies at law, without having to prove the inadequacy thereof and without
being required to post bond or other security therefor. In the event Purchaser
fails to consummate the transaction herein contemplated by the Termination Date,
and provided that (i) the representations and warranties of Seller set forth
herein are true and correct on such date; (ii) all conditions precedent to
closing have been satisfied; and (iii) Seller has complied with all of its
obligations hereunder, Seller shall have the right to terminate this Agreement
after the Closing Date upon three (3) days prior written notice to Purchaser.

         17. Reliance on and Survival of Agreement. Each of the parties to this
Agreement shall be entitled to rely upon the representations and warranties of
the other party contained in this Agreement or any other agreement, document or
other instrument delivered pursuant hereto, and upon the representations of the
other party at Closing as to compliance with or performance of any covenants
made by it herein or therein and as to satisfaction of any conditions precedent
to the obligations of such party hereunder. All covenants, representations and
warranties in this Agreement or in any agreement, document, or other instrument
delivered by or on behalf of a party pursuant hereto and the indemnification
obligations of the parties hereto relating to such representations and
warranties shall survive and continue in effect for a period of eighteen (18)
months after the Closing.

         18. Remedies Not Exclusive. The remedies provided in this Agreement
shall not be exclusive of any other rights or remedies available by one party
against the other, either at law or in equity, including without limitation, the
right of any party prevailing in litigation arising from this Agreement to
recover its attorneys fees and costs.

         19. Efforts to Consummate. Subject to the terms and conditions of this
Agreement, each party hereto shall use commercially reasonable efforts to take
or cause to be taken all actions and do or cause to be done all things required
under applicable law in order to consummate the transactions contemplated
hereby, including, without limitation, (i) obtaining all permits,
authorizations, consents and approvals of any authority or other person which
are required for the consummation of the transactions contemplated hereby and by
the other documents, (ii) taking any and all reasonable actions necessary to
satisfy all of the condition to such party's obligations hereunder, and (iii)
executing and delivering all agreements and documents required by the terms
hereof to be executed and delivered by such party on or prior to the Closing.

         20. Assignment. Only Purchaser shall have the right to assign its
rights under this Agreement on written notice to Seller.

                                       13

         21. Notices. Any notice or other communication to be given under this
Agreement by any party to any other party shall be in writing and shall be
either (a) personally delivered, (b) delivered by overnight express delivery
service or same-day local courier service, or (c) delivered by telex or
facsimile transmission, to the address set forth below the signature line of
each party hereto, or to such other address as may be designated by the parties
from time to time in accordance with this section. Notices delivered personally,
by overnight express delivery service or by local courier service shall be
deemed given as of actual receipt. Notices delivered by facsimile transmission
shall be deemed given upon receipt by the sender of the transmission
confirmation.

         22. Miscellaneous. This Agreement and the Exhibits attached hereto
supersede all prior agreements and understandings relating to the subject matter
hereof, except that the obligations of any party under any agreement executed
pursuant to this Agreement shall not be affected by this paragraph, and this
Agreement may be amended only in writing executed by the parties hereto or their
authorized representatives. This Agreement and the rights and obligations of the
parties hereto shall be governed by and construed and enforced in accordance
with the laws of the State of Georgia. This Agreement and the rights, interests
and obligations hereunder shall be binding upon and shall inure to the benefit
of the parties hereto and their respective heirs, personal representatives,
estates, devisees, successors and permitted assigns. The captions in this
Agreement are for convenience of reference only and shall not limit or otherwise
affect any of the terms or provisions hereof. This Agreement may be executed in
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

         23. Costs, Expenses, and Legal Fees. Each party hereto agrees to pay
the costs and expenses, including reasonable attorneys' fees, incurred by the
prevailing party in litigation or in an administrative proceeding to enforce or
interpret any of the terms of this Agreement.

         24. Severability. If any provision of this Agreement is held to be
illegal, invalid, or unenforceable under present or future laws effective during
the term hereof, the provision shall be fully severable and this Agreement shall
be construed and enforced as if such illegal, invalid, or unenforceable
provision were never a part hereof; and the remaining provisions hereof shall
remain in full force and effect and shall not be affected by the illegal,
invalid, or unenforceable provision or by its severance herefrom.

         2. Sale and Purchase. Subject to the terms and conditions hereof,
Purchaser hereby agrees to purchase and accept from Seller, and Seller hereby
agrees to sell, convey and assign to Purchaser, the Property, free and clear of
any liens or encumbrances.

         3. Purchase Price; Adjustment.

              A. On the Closing Date, Purchaser shall deliver the Purchase Price
to Seller by certified check or wire transfer.

              B. The Purchase Price is based on Seller's representation of the
annualized Tower Cash Flow set forth on Exhibit "B" attached hereto and made a
part hereof. Prior to the Closing Date, Purchaser shall verify the accuracy of
the calculation of Tower Cash Flow specified in Exhibit "B", based on the
information to be provided to Purchaser by Seller pursuant to Section 9 hereof.
In the event Purchaser determines prior to the Closing Date that Tower Cash Flow
as of the date hereof, as annualized based on the actual income and expenses of
the Sites for the twelve (12) month period preceding the date hereof, is less
than $143,257.44, then the Purchase Price shall be adjusted to equal the product
of 10.5 and Tower Cash Flow as determined by Purchaser. Further, in the event
that this Agreement is terminated with respect to one of the two Sites, then the
Purchase Price shall be adjusted to equal the Adjusted Purchase Price for the
remaining Site according to its Tower Cash Flow, as such Tower Cash Flow is
determined by Purchaser.

              In the event that the reduction in Tower Cash Flow is caused
solely or in part by the fact that Nextel Partners has not fully installed and
commenced on the Moody site as of the Closing Date, the Purchase Price paid to
Seller at the Closing shall be reduced by $200,000.00 (the "Escrow Amount") and
Tower Cash Flow shall be considered $124,057.44 for other adjustment purposes.
The Escrow Amount shall be placed in an escrow account with an escrow agent of
Purchaser's choice for a period of nine (9) months (the "Escrow Period"). If
Nextel Partners fully installs and its lease fully commences within the Escrow
Period the Escrow Amount, and all interest earned thereon, shall be paid to
Seller. If Nextel Partners fails to fully install and/or its lease has not
commenced within the Escrow Period, the Escrow Amount and the interest earned
thereon shall be paid to Purchaser.

         4. Prorations; Costs. All taxes, rental income, utility charges, ground
rents (if applicable) and other items which are customarily prorated in
transactions similar to the transaction contemplated hereby will be prorated as
of the Closing Date. After the Closing Date, promptly upon receipt of any rental
payments under the Tower Leases for periods after the Closing Date, Seller shall
pay over to Purchaser all such cash received by Seller or endorse and deliver to
Purchaser all such checks or other instruments so received by Seller. To the
extent any of the amounts prorated at Closing are based on estimates, or in the
event of any inaccuracy in such amounts, Purchaser shall provide to Seller
evidence of any discrepancy between the prorated amounts and the actual amounts
shown on the closing statement within sixty (60) days of the Closing Date,
together with the reconciliation reflecting such actual amounts. To the extent
such reconciliation indicates that either party is due additional prorated
amounts, such amounts shall be paid by the party from whom such amounts are due
within ninety (90) days of the Closing Date. Purchaser shall bear the costs of
recordation, and any deed or transfer taxes arising with respect to the sale
and/or recordation of any of the Closing documents. Purchaser shall bear the
expense of any surveys or other reports or investigations conducted by
Purchaser, as well as any mortgage tax.

delivered, the documents and items described below and such other appropriate

its lender; (vii) a Non-Disturbance Agreement from any mortgage lender to any

contemporaneously herewith or otherwise reasonably satisfactory to Purchaser and
its lender, if applicable; (viii) any consents or approvals required to be
obtained pursuant to the Commitments (as hereinafter defined), the Ground Leases
or the Tower Leases; (ix) such other documents as may be reasonably required by
Purchaser's title company to complete the Closing of the transaction
contemplated herein, including without limitation, a resolution or other

such additional actions as either party or its counsel may reasonably deem to be
practicable and necessary or advisable in order to consummate the transaction
contemplated by this Agreement.

         6. Representation and Warranties of Seller. Seller represents and
warrants the following to Purchaser as of the Effective Date, which
representations and warranties shall be true and correct as of the Closing Date:

              A. Organization; Power and Authority; Authorization and Validity.
Seller is a Georgia limited liability company in good standing with full power
and authority to execute, deliver, and perform its obligations under this
Agreement and all other agreements and documents Seller is or will be executing
in connection with the transaction contemplated hereby.

              B. No Commitments, Defaults or Litigation. To the best of Seller's
actual knowledge, none of the Property is bound or affected by any (i) mortgage,
deed of

                                       4

trust, loan or other security agreement that will not be satisfied at Closing or
the subject of a Non-Disturbance Agreement to be obtained by Seller; (ii)
contract to purchase or sell; (iii) noncompetition covenant; (iv) option or
right of first refusal; or (v) any other agreement or commitment outside the
ordinary course of business or material to the ownership and operation of the
Sites or the Facilities (all of the foregoing collectively referred to
hereinafter as the "COMMITMENTS"). True and complete copies of the Ground
Leases, the Tower Leases, Intangibles and the Permits that are evidenced by
written documents have been delivered to Purchaser. There are no existing
material defaults, events of default or events, occurrences, or acts that, with
the giving of notice or lapse of time or both, would constitute defaults, and no
penalties have been incurred, with respect to any of the Ground Leases, the
Tower Leases or Permits; and except as disclosed to Purchaser in writing, none
of the foregoing documents require the consent of any third party to the
transactions contemplated hereby. Seller has not received any rents or other
amounts due Seller under the Tower Leases in respect of any period exceeding
thirty (30) days from the date hereof. All tenants under the Tower Leases have
deployed their respective equipment at the Facilities, and no such tenant has
advised Seller that such tenant intends to exercise any right of termination set
forth in the Tower Leases. Seller has no knowledge of any litigation or
proceedings affecting Seller or the Property that have not been disclosed to
Purchaser.

              C. No Oral Agreements. No oral agreements pertaining to the
Property exist between Seller and any other party.

              D. No Violation; Restrictions. Neither the execution and
performance of this Agreement or the agreements contemplated hereby, nor the
consummation of the transaction contemplated hereby or applicable to the
Property thereby will violate Applicable Law or any term of any Permit or give
any party the right to revoke any Permit. To the best of Seller's knowledge,
Seller has complied in all material respects with all Applicable Law where the
failure to comply could either result in a liability of Purchaser or affect the
Property or the operation of the Facilities. To the best of Seller's knowledge,
the Permits constitute all licenses, franchises, permits, zoning variances, and
other authorizations necessary to construct and operate the Facilities in
compliance with Applicable Law.

              E. Commissions. Neither Seller nor Purchaser has incurred any
obligation for any real estate commission, finder's, broker's, or agent's fee in
connection with the transaction contemplated hereby.

              F. Financial. The Tower Leases and the Ground Leases are valid and
enforceable, and constitute the entirety of the agreement between Seller and the
parties thereto, and there are no unwritten agreements, indirect or undisclosed
payments or other consideration due or which shall become due to the parties to
such agreements except as expressly set forth in the written terms thereof.
Exhibit "C" is true and accurate in all material respects, and sets forth, for
each Tower Lease, the tenant name, Site name, contracted rental amount,
escalator, frequency of escalator and number of tenant renewal options. The
calculation of Tower Cash Flow set forth on Exhibit "B" accurately specifies the
income and expenses for Sites, and Seller is not aware of any circumstances that
could materially and adversely affect Tower Cash Flow as set forth on Exhibit
"B".

                                       5

              G. Environmental Matters.

                   (a) To the best of Seller's knowledge Seller is not in
              violation of, or involved in any controversy, investigation, or
              discussion with respect to, any environmental law, and there is no
              fact or condition related the operation of the Facilities or the
              ownership or use of the Real Property by Seller that could lead to
              any environmental liability of Seller or Purchaser. To the best of
              Seller's knowledge Seller has complied with all environmental,
              health, and safety laws, and no action, suit, proceeding, hearing,
              investigation, charge, complaint, claim, demand, or notice has
              been filed or commenced against it alleging any failure to so
              comply. Without limiting the generality of the preceding sentence,
              to the best of Seller's knowledge Seller has obtained and been in
              material compliance with all of the terms and conditions of all
              permits, licenses, and other authorizations that are required
              under, and has materially complied with all other limitations,
              restrictions, conditions, standards, prohibitions, requirements,
              obligations, schedules, and timetables that are contained in, all
              environmental, health, and safety laws;

                   (b) No underground storage tanks for petroleum or any other
              substance, or underground piping or conduits are or have
              previously been located on the Real Property, and no
              asbestos-containing thermal insulation or products containing PCB,
              formaldehyde, chlordane, or heptachlor or other Hazardous
              Materials have been placed on or in any structure on the Real
              Property by Seller or, to the knowledge of Seller, by any prior
              owner or user of the Real Property, and there has been no release
              of, or contamination by, Hazardous Materials on the Real Property;
              and

                   (c) Seller has provided Purchaser with all environmental
              studies, NEPA reports, records and reports in its possession or
              control with respect to Property and all correspondence with any
              governmental entities concerning environmental or historical
              conditions of the Real Property, or which identify underground
              storage tanks or otherwise relate to contamination of the soil or
              groundwater of the Real Property or effluent into the air. As used
              herein, "HAZARDOUS MATERIALS" means any substance designated as
              being such under any Applicable Law.

              H. Real Estate Matters.

                   (a) On or before the Closing Date, Seller will deliver or
              cause to be delivered good and marketable title to, and peaceful
              possession of, the Real Property, and, as of such time, there
              shall be no outstanding liens or taxes due on the Real Property it
              owns that will not be satisfied out of the Closing proceeds. On or
              before the Closing Date, Seller will have fully paid and satisfied
              all outstanding taxes due on the Property, and all amounts due to
              parties providing services or materials with respect to the
              acquisition, construction and development of the Sites, and no
              such party has the choate or inchoate right to record a lien or
              other such encumbrance against the Real Property.

                                       6

                   (b) The Real Property, communication tower and all buildings,
              improvements, machinery, tower lighting, equipment, and other
              tangible assets necessary for the operation of the Facilities, as
              presently conducted, are, to the best of Seller's knowledge, in
              compliance with all Applicable Laws. There are no outstanding
              NOTAM's with respect to the Facilities which have not been
              properly closed as required by Applicable Law.

                   (c) The communication towers and all buildings, improvements,
              machinery, equipment relating to the use and operation of the Real
              Property as a communications tower site, including without
              limitation, any climate control, lighting system, electrical
              system and other building equipment, have been maintained in
              accordance with customary industry practice, are in good operating
              condition and repair, and are suitable for the purposes for which
              they are presently used. There are no structural or latent defects
              in the aforesaid communication towers, equipment and improvements.

                   (d) Seller has not received notice of, or been served with,
              any pending or threatened litigation, claim, condemnation, or sale
              in lieu thereof with respect to any portion of the Real Property
              relating to or arising out of the ownership of the Real Property
              by any governmental instrumentality.

                   (e) Seller has no knowledge of any rollback taxes or any
              proposed material increase in real property taxes levied against
              the Real Property and no exemption from full taxation of any
              portion of the Real Property has been claimed within the previous
              five (5) years. The personal and real property tax amounts for
              prior years provided by Purchaser to Seller pursuant to Section 9
              hereof are true and correct in all material respects.

                   (f) Each parcel of Real Property abuts on and has direct
              vehicular access to a public road, or has access to a public road
              via a permanent, irrevocable, appurtenant easement benefiting the
              Real Property, and Seller has no knowledge of any fact or
              condition that could result in the termination or reduction of the
              current access from the Real Property to existing highways and
              roads, or to sewer or other utility services serving the Real
              Property. All utilities required for the operation of the
              Facilities, enter the Real Property through adjoining public
              streets, or, if they pass through an adjoining private tract, do
              so in accordance with valid easements. Each parcel of Real
              Property owned by Seller or, constitutes a separate tax parcel and
              has been properly subdivided as a separate lot of record, to the
              extent required by Applicable Law.

         7. Management of Facilities Before Closing Date. During the period
pending the Closing, except as otherwise permitted or required by this
Agreement, Seller shall (i) conduct the operations of the Facilities in the
ordinary and usual course of business consistent with past and current
practices; and shall not make any material changes to the Property or its
operation without the prior consent of Purchaser; (ii) notify Purchaser of
material changes or adverse conditions with respect to the operation of the
Property; (iii) maintain casualty and liability insurance amounts and coverages
as required by the Ground Leases and Tower Leases; (iv) not enter into any
leases or licenses of the Sites

                                       7

without the prior written approval of Purchaser, (v) not solicit or authorize
any person to solicit, or encourage, any inquiry or proposal for the sale or
financing of all or any material part of the Property or enter into negotiations
for any such proposal; (vi) exercise commercially reasonable efforts to remedy,
at the sole expense of Seller, all liens, claims or impairments to the
marketability of title to the Real Property, violations of Applicable Law or
other legal requirements relating the construction, development and operation of
the Property; (vii) exercise commercially reasonable efforts to obtain such
ground lease estoppels and nondisturbance agreements as reasonably required by
Purchaser or its Lender; and (viii) not enter into any Commitment or transaction
that could materially or adversely affect the Facilities or the Property.

         8. Noncompetition; Rights of First Refusal. Seller and its undersigned
principal, who joins in this Agreement intending to be bound by the terms of
this Section, covenant and agree that the proprietary information Seller and its
undersigned principal have acquired regarding the Facilities will enable Seller
and its undersigned principal to injure Purchaser and diminish the value of the
investment in the Property by Purchaser if Seller or its undersigned principal
should compete with Purchaser. Therefore, Seller and its undersigned principal
hereby agree that, without the prior written consent of Purchaser, neither
Seller nor its undersigned principal, shall for three (3) years from the Closing
Date, directly or indirectly, as a director, officer, agent, employee,
consultant or independent contractor or in any other capacity, (a) invest (other
than investments in publicly owned companies which constitute not more than ten
(10%) percent of the voting securities of any such company) or engage in any
business or activity that competes with the Facilities within a three (3) mile
radius of the Real Property (the "TERRITORY"); (b) render services to a
competitor of Purchaser in the Territory, unless such services have been first
offered by Seller to Purchaser or (c) contact, solicit or attempt to solicit or
accept business that competes with the Facilities from any of the customers of
the Facilities in the Territory.

         9. Inspection by Purchaser. Seller shall permit Purchaser and its
authorized representatives reasonable access to, and make available all of the
Property of Seller and the business premises of Seller and its employees, and
furnish to Purchaser all books, records, documents, corresponding engineering
and environmental reports, contracts, property and sale tax records, Commitments
and information with respect to the Property and the affairs of Seller. Further,
Purchaser shall have the right to contact all tenants and prospective tenants
under Tower Leases, the lessor under the Ground Leases and such other parties as
Purchaser reasonably determines in connection with the inspection of the
Property. In the event Purchaser determines that either of the Sites is unfit
for Purchaser's intended use as a communication tower facility, Purchaser shall
have the right and option to terminate this Agreement as to either one or both
of the Sites, at Purchaser's option, by providing written notice of such
termination to Seller prior to the Closing Date. In the event this Agreement is
terminated as to only one (1) Site, the Purchase Price will be reduced to the
Adjusted Purchase Price. Following the Closing Date, Purchaser may be required
to conduct audits of its business and any business it has acquired in connection
with additional financing of Purchaser, and Seller agrees to cooperate with
Purchaser in any such post-closing audits, as reasonably requested by Purchaser.

         10. Conditions Precedent Purchaser's Right to Terminate.
Notwithstanding any provision to the contrary set forth herein, and except as
may be waived in writing by Purchaser, the obligations of Purchaser hereunder
are subject to the fulfillment at or before the Closing of each of the following
conditions, and Purchaser shall have the right to

                                       8

terminate this Agreement, as to the affected Site(s) only or as to either one or
both of the Sites, at Purchaser's option, in the event all of the following
conditions are not satisfied on or before the Closing Date: (i) Purchaser has
verified to its reasonable satisfaction that each representation and warranty of
Seller contained herein is true and correct in all material respects and shall
be true and correct in all material respects as of the Closing; (ii) Seller
shall have performed and complied with all covenants or conditions required by
this Agreement to be performed and complied with by Seller at or before the
Closing, including, without limitation, delivery of all documents and items
described in Section 5.B; (iii) Purchaser's receipt and approval of all Permits;
(iv) Purchaser's receipt and approval of a Phase I Environmental Assessment and
NEPA report as to each Site; and (v) Purchaser shall have received an owner's
policy of title insurance insuring title to the Real Property, in form and
substance satisfactory to Purchaser, in Purchaser's sole discretion. In the
event Purchaser elects to terminate this Agreement as to only one (1) Site, this
Agreement shall continue and remain in full force and effect as to the remaining
Site, except that the Purchase Price shall be the Adjusted Purchase Price. In
addition to the foregoing right to terminate this Agreement, in the event one or
more of the foregoing conditions are not satisfied at Closing due to any
outstanding taxes, lien or title claim, Purchaser shall have the right to
satisfy such outstanding lien or claim by payment to the lienor or claimant
directly, and the amount of such payment shall be deducted from the Purchase
Price.

         11. Casualty; Condemnation. In the event of casualty damage or
condemnation (or notice thereof) of a material portion of either Site occurs
prior to Closing, Purchaser shall have the right to either terminate this
Agreement as to such Site, or to proceed to Closing. In the event Purchaser
elects to terminate this Agreement as to either Site, this Agreement shall
continue and remain in full force and effect as to the remaining Site, except
that the Purchase Price shall be the Adjusted Purchase Price. In the event
Purchaser elects to any proceed to Closing as to such Site, Seller shall assign
to Purchaser all insurance proceeds, claims or condemnation proceeds arising
from such casualty damage or condemnation.

         12. Confidentiality. Without the prior written consent of Purchaser,
Seller will not disclose, and will not permit its representatives to disclose,
to any person other than its officers, directors and advisors (i) the fact that
discussions or negotiations are taking place concerning the transaction
contemplated hereby, or (ii) any of the terms, conditions or other facts with
respect to the transaction, including the status thereof, except to the extent
that Seller has, prior to any such disclosure, determined in good faith, after
consultation with counsel, that such disclosure is required by Applicable Law.

         13. Indemnity by Seller. Each of Seller and its undersigned principal
hereby agrees to indemnify, defend, and hold harmless Purchaser and its
officers, directors, shareholders, agents, and attorneys for, from, and against
all damages, claims, loss, costs (including attorneys fees) asserted against or
incurred by any of them by reason of, or resulting from: (i) any breach by
Seller of any representation, warranty, or covenant contained herein or in any
agreement executed pursuant hereto; (ii) all liabilities of Seller not expressly
assumed by Purchaser pursuant to the terms hereof; (iii) the construction,
operation and ownership of the Property through the Closing Date (collectively,
"DAMAGES"). Without limiting the generality of the foregoing, the
indemnification provided by this paragraph shall specifically cover capital,
operating, and maintenance

                                       9

costs, incurred in connection with any investigation or monitoring of site
conditions, any clean-up, containment, remedial, removal, or restoration work
required or performed by any federal, state, or local governmental agency or
political subdivision or performed by any nongovernmental entity or person
because of the presence, suspected presence, release, or suspected release of
any Hazardous Material in or into the air, soil, groundwater, or surface water
at, on, about, under, or within the Real Property (or any portion thereof).

         14. Remedies. If Seller fails to comply with this Agreement for any
reason other than Purchaser's failure to perform its obligations under this
Agreement, Purchaser shall be entitled to either (i) enforce specific
performance of Seller's obligations hereunder, or (ii) terminate this Agreement,
and recover any damages incurred by Purchaser. Seller acknowledges that a breach
of the terms hereof by Seller, or refusal by Seller to consummate the
transaction contemplated hereby will cause irrevocable harm to Purchaser, for
which there may be no adequate remedy at law and for which the ascertainment of
damages would be difficult. For this reason, Seller has agreed that in the event
of a default by Seller, Purchaser shall be entitled to specific performance or
injunctive relief in addition to other remedies at law, without having to prove
the inadequacy thereof and without being required to post bond or other security
therefor.

         15. Indemnity by Purchaser. From and after the Closing Date, and
provided that all representations and warranties of Seller set forth herein are
true and correct as of the Closing Date, Purchaser shall indemnify, defend and
hold harmless Seller and its officers, directors, shareholders, agents, and
attorneys for, from, and against all Losses asserted against or incurred by any
of them by reason of, or resulting from the failure of Purchaser to comply with
(i) any covenants or other commitments made by Purchaser in this Agreement, (ii)
such covenants and commitments set forth in the Ground Leases and Tenant Leases
that are expressly assumed by Purchaser, provided that such Losses result from
matters arising after the Closing Date.

         16. Remedies Not Exclusive. The remedies provided in this Agreement
shall not be exclusive of any other rights or remedies available by one party
against the other, either at law or in equity, including without limitation, the
right of any party prevailing in litigation arising from this Agreement to
recover its attorneys fees and costs.

         17. Reliance on and Survival of Agreement. Notwithstanding any
investigation by Purchaser, or any information obtained pursuant thereto,
Purchaser shall be entitled to rely upon the representations and warranties of
Seller contained in this Agreement or any other agreement, document or other
instrument delivered pursuant hereto, and upon the representations of Seller at
Closing as to compliance with or performance of any covenants made by it herein
or therein and as to satisfaction of any conditions precedent to the obligations
of Purchaser hereunder. All covenants, representations and warranties in this
Agreement or in any agreement, document, or other instrument delivered by or on
behalf of a party pursuant hereto and the indemnification obligations of the
parties hereto relating to such representations and warranties shall survive and
continue in effect for a period of twelve (12) months after the Closing.

         18. Assignment. Neither this Agreement nor any right created hereby
shall be assignable by either party hereto, except by Purchaser to any direct or
indirect wholly owned subsidiary or Affiliate (as hereinafter defined) of
Purchaser. As used herein, "Affiliate" shall mean any corporation, partnership,
limited liability company, limited liability partnership, trust or other
juridical person under direct or indirect common control with Purchaser.

                                       10

         19. Notices. Any notice or other communication to be given under this
Agreement by any party to any other party shall be in writing and shall be
either (a) personally delivered, (b) mailed by registered or certified mail,
postage prepaid with return receipt requested, (c) delivered by overnight
express delivery service or same-day local courier service, or (d) delivered by
telex or facsimile transmission, to the address set forth below the signature
line of each party hereto, or to such other address as may be designated by the
parties from time to time in accordance with this section. Notices delivered
personally, by overnight express delivery service or by local courier service
shall be deemed given as of actual receipt. Mailed notices shall be deemed given
three (3) business days after mailing. Notices delivered by telex or facsimile
transmission shall be deemed given upon receipt by the sender of the answerback
(in the case of a telex) or transmission confirmation (in the case of a
facsimile transmission).

         20. Miscellaneous. This Agreement and the Exhibits attached hereto
supersede all prior agreements and understandings relating to the subject matter
hereof, except that the obligations of any party under any agreement executed
pursuant to this Agreement shall not be affected by this paragraph, and this
Agreement may be amended only in writing executed by the parties hereto or their
authorized representatives. This Agreement and the rights and obligations of the
parties hereto shall be governed by and construed and enforced in accordance
with the laws of the State of Georgia. This Agreement and the rights, interests
and obligations hereunder shall be binding upon and shall inure to the benefit
of the parties hereto and their respective heirs, personal representatives,
estates, devisees, successors and permitted assigns. The captions in this
Agreement are for convenience of reference only and shall not limit or otherwise
affect any of the terms or provisions hereof. This Agreement may be executed in
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument. Time is of the essence of each
provision of this Agreement.

         21. Costs, Expenses, and Legal Fees. Each party hereto agrees to pay
the costs and expenses, including reasonable attorneys' fees, incurred by the
prevailing party in litigation or in an administrative proceeding to enforce or
interpret any of the terms of this Agreement.

         22. Severability. If any provision of this Agreement is held to be
illegal, invalid, or unenforceable under present or future laws effective during
the term hereof, the provision shall be fully severable and this Agreement shall
be construed and enforced as if such illegal, invalid, or unenforceable
provision were never a part hereof; and the remaining provisions hereof shall
remain in full force and effect and shall not be affected by the illegal,
invalid, or unenforceable provision or by its severance herefrom.
