partnership interests in NTS Properties III, (the "Partnership") being sold
pursuant to this Agreement of Sale ("Agreement") and indicated on the signature
pages to this Agreement, for a purchase price of $275 per Unit and less the
amount of any distributions declared or paid from any source by the Partnership
with respect to the Units after July 18, 2001 without regard to the record date
or whether such distributions are classified as a return on, or a return of,
capital.

PAYMENT FOR UNITS BEING SOLD PURSUANT TO THIS AGREEMENT WILL BE MADE WITHIN TEN
(10) BUSINESS DAYS FOLLOWING THE "EXPIRATION DATE" SET FORTH IN THE OFFER TO
PURCHASE ACCOMPANYING THIS AGREEMENT, PROVIDED LEXINGTON FUND HAS RECEIVED AND

ASSURANCES FROM THE PARTNERSHIP THAT THE SELLER'S ADDRESS WILL BE CHANGED TO THE
PURCHASER'S ADDRESS PURSUANT TO THE TERMS AND CONDITIONS OF THE OFFER.

The Seller hereby represents and warrants to the Purchaser that the Seller owns
all of the Units being sold hereunder and has full power and authority to
validly sell, assign, transfer, convey, and deliver to the Purchaser such Units,
and that when any such Units are accepted for payment by the Purchaser, the
Purchaser will acquire good, marketable and unencumbered title thereto, free and
clear of all options, liens, restrictions, charges, encumbrances, conditional
sales agreements, or other obligations relating to the sale or transfer thereof,
and such Units will not be subject to any adverse claim. The Seller represents
and warrants that the Seller is a "United States person" as defined in Section
7701(a)(30) of the Internal Revenue Code of 1986, as amended, or if the Seller
is not a United States person, the Seller does not own beneficially or of record
more than 5 percent of the outstanding Units. The Seller also represents and
warrants that in deciding to sell the Units to the Purchaser, the Seller has not
relied upon any representation or warranty made by the Purchaser or any agent of
the Purchaser with respect to the value of the Units or the income tax
consequences of the sale of the Units.

The sale of Units pursuant to this Agreement shall include, without limitation,
all rights in, and claims to, any Partnership profits and losses, cash
distributions, voting rights and other benefits of any nature whatsoever,
distributable or allocable to such Units under the Partnership's Agreement of
Limited Partnership. Upon the execution of this Agreement by the Seller,
Purchaser shall have the right to receive all benefits and cash distributions
and otherwise exercise all rights of beneficial ownership of such Units.
Additionally, the sale of Units pursuant to this Agreement shall include an
assignment by the Seller to the Purchaser of the Seller's right to pursue any
legal or other action of recovery against any person or entity which might be
liable in any way to the Seller as a result of his purchase and ownership of the
Units (or any interest therein) being sold hereby. Any damages or recoveries
resulting from such actions, whether initiated by the Purchaser or by other
parties will be due and payable to the Purchaser.

Seller, upon execution of this Agreement, hereby irrevocably constitutes and
appoints Purchaser as its true and lawful agent and attorney-in-fact with
respect to the Units being sold hereby with full power of substitution. This
power of attorney is an irrevocable power, coupled with an interest of the
Seller to Purchaser, to (i) execute, swear to, acknowledge, and file any
document relating to the assignment of the Units being sold hereby on the books
of the Partnership that are maintained with respect to the Units and on the
Partnership's books maintained by the General Partner of the Partnership, or
amend the books and records of the Partnership as necessary or appropriate for
the assignment of the Units, (ii) vote or act in such manner as any such
attorney-in-fact shall, in its sole discretion, deem proper with respect to the
Units being sold hereby, (iii) deliver the Units being sold hereby and transfer
ownership of such Units on the books of the Partnership that are maintained with
respect to the Units and on the Partnership's books, maintained by the
Partnership's General Partner, (iv) endorse on the Seller's behalf any and all
payments received by Purchaser from the Partnership for any period on or after
July 18, 2001 which are made payable to the Seller, in favor of Purchaser, (v)

distribution agreements required by the National Association of Securities
Dealers, Inc.'s Notice to Members 96-14 to give effect to the transaction
contemplated by this Agreement, (vi) receive all distributions and inspect and
amend the books and records of the Partnership, including Seller's address and
records, to direct all distributions to Purchaser as of the effective date of
this Agreement, (vii) withdraw any previous tender of this Unit(s), and (viii)
request an accounting of the affairs of the Partnership. Purchaser shall not be
required to post bond of any nature in connection with this power of attorney.

SELLER DOES HEREBY DIRECT AND INSTRUCT THE PARTNERSHIP AND THE GENERAL PARTNER
IMMEDIATELY UPON THEIR RECEIPT OF THIS AGREEMENT OF SALE (I) TO AMEND THE BOOKS
AND RECORDS OF THE PARTNERSHIP TO CHANGE THE SELLER'S ADDRESS OF RECORD FOR
PURPOSES OF MAILING DISTRIBUTIONS WITH RESPECT TO THE UNITS BEING SOLD HEREBY TO
EQUITY RESOURCE LEXINGTON FUND, LP C/O EQUITY RESOURCES GROUP, INC., 14 STORY
STREET CAMBRIDGE, MA 02138 AND (II) TO FORWARD ALL DISTRIBUTIONS AND ALL OTHER
INFORMATION RELATING THEREIN TO BE RECEIVED BY SELLER TO EQUITY RESOURCE
LEXINGTON FUND, LP TO THE ADDRESS SET FORTH IN (I) ABOVE.

Seller does hereby release and discharge the General Partner and their officers,
shareholders, employees and agents from all actions, causes of actions, claims
or demands Seller has, or may have, against the General Partner that result from
the General Partner's reliance on this Agreement or any of the terms and
conditions contained herein. Seller agrees to indemnify and hold the Purchaser
and the Partnership harmless from and against, and to reimburse the Purchaser
and/or the Partnership on demand, for any damage, loss, cost or expense
(including attorneys' fees and costs of investigation incurred in defending
against and/or settling such damage, loss, cost or expense) reasonably incurred
by the Purchaser and/or the Partnership arising out of or in connection with any
misrepresentation, breach of warranty, or failure to perform or violation of any
agreement or covenant on the part of the Seller under this Agreement.

All authority herein conferred or agreed to be conferred shall survive the death
or incapacity of the Seller and any obligations of the Seller shall be binding
upon the heirs, personal representatives, successors and assigns of the
undersigned. This agreement is irrevocable and may not be withdrawn following.
Upon request, the Seller will execute and deliver any additional documents
deemed by the Purchaser or the Partnership to be necessary or desirable to
complete the assignment, transfer and purchase of such Units.



If the Seller is more than one person, then and in such event, the obligations
of the Seller under this Agreement shall be joint and several and the
representations, warranties and covenants herein contained shall be deemed to be
made by and binding upon each such person and his heirs, executors,
administrators, successors and assigns. The representations, warranties,
covenants and agreements contained in this Agreement shall survive the transfer
of the Units made by this Agreement and the payment of the consideration
therefor.

The Seller hereby certifies, under penalties of perjury, that (i) the tax
identification number shown on this form is the Seller's correct Taxpayer
Identification Number; and (ii) Seller is not subject to backup withholding
either because Seller has not been notified by the Internal Revenue Service (the
"IRS") that Seller is subject to backup withholding as a result of failure to
report all interest or dividends, or the IRS has notified Seller that Seller is
no longer subject to backup withholding.

The Seller hereby also certifies, under penalties of perjury, that the Seller,
if an individual, is not a nonresident alien for purposes of U.S. income
taxation, and if not an individual, is not a foreign corporation, foreign
partnership, foreign trust, or foreign estate (as those terms are defined in the
Internal Revenue Code and Income Tax Regulations). The Seller understands that
this certification may be disclosed to the IRS by the Purchaser and that any
false statements contained herein could be punished by fine, imprisonment, or
both.

The undersigned recognizes that, if proration is required pursuant to the terms
of the Offer, the Purchaser will accept for payment from among those Units
validly tendered on or prior to the Expiration Date and not properly withdrawn,
the maximum number of Units permitted pursuant to the Offer on a pro rata basis.
The undersigned understands that a tender of Units to the Purchaser will
constitute a binding agreement between the undersigned and the Purchaser upon
the terms and subject to the conditions of the Offer. The undersigned recognizes
that under certain circumstances set forth in the Offer to Purchase, the
Purchaser may not be required to accept for payment any of the Units tendered
hereby. In such event, the undersigned understands that any Agreement for Units
not accepted for payment will be destroyed by the Purchaser.

This Agreement shall be governed by and construed in accordance with the laws of
the Commonwealth of Massachusetts. Seller waives any claim that any court in
Massachusetts is an inconvenient forum, and waives any right to trial by jury.

The undersigned Seller (including any joint owner(s)) owns and wishes to assign
the number of Units set forth below. By its own or its Authorized Signatory's
signature below, the Seller hereby assigns its entire right, title and interest
in the Units set forth below to the Purchaser.

By executing this Agreement, the Seller hereby acknowledges to the General
Partner that the Seller desires to assign the Units referenced herein and hereby
directs the General Partner to take all such actions as are necessary to
accomplish such assignment, and appoints the General Partner the agent and
attorney-in-fact of the Limited Partner, to execute, swear to, acknowledge and
file any document or amend the books and records of the Partnership as necessary
or appropriate for the assignment of the withdrawal of the Limited Partner.

Each of the Parties hereto agrees to promptly execute and deliver any and all
further agreements, documents or instruments necessary to effectuate this
Agreement and the transaction referred to herein or reasonably requested by the
other party to perfect or evidence its or his rights hereunder.

Should either party hereto commence any proceeding to enforce the provisions of
this Agreement, then and in such event, the prevailing party in any such
proceeding or action shall be entitled to reimbursement of its or his costs,
including attorney's fees, incurred in the investigation and prosecution of such
proceeding or action. The parties agree that the proper venue for any such
action shall be in the County of Middlesex, Commonwealth of Massachusetts, and
the Seller hereby consents to the jurisdiction over the Seller by the state and
Federal courts of or in the Commonwealth of Massachusetts, County of Middlesex
in connection with any proceeding or action brought under this Assignment.

Any provision of this Agreement that is invalid or unenforceable in any
jurisdiction shall, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering invalid or unenforceable
the remaining provisions of this Agreement or affecting the validity or
enforceability of any provisions of this Agreement in any other jurisdiction.
