Re:   200 Cook Street, Cartersville, GA (the "Property")

Dear Murray:

        In  connection  with the delivery by NAN  Investors,  L.P.  ("NAN") of a
Quitclaim  Deed (the  Quitclaim  Deed) with  respect to the Deed to Secure Debt,
Security  Agreement and  Assignment of Leases and Rents,  filed for record as of
August  19,  1996 by the  Company  in favor of NAN (the  "Mortgage"),  Nantucket
Industries, Inc. (the "Company") hereby confirms to you as follows:

         1. The  Company  is  currently  in  default  under the two  Convertible
Subordinated Debentures payable to NAN, dated August 15, 1996 (collectively: the
"Debentures"),  in the original  principal amounts of $1,168,150 and $1,591,850,
respectively,  among  other  things for  failure by the  Company to make  timely
payment of the interest payment due under the Debentures on August 15, 1997 (the
"Interest Payment Default").

        2.  Furthermore,  the  Company  acknowledges  that  it has no  right  of
prepayment under the Debentures and that the proposed sale by the Company of the
Property  represents  an  additional  Event of Default by the Company  under the
Debentures (the "Property Sale Default"). Finally, the Company acknowledges that
it has no right to demand that NAN release the Mortgage on the  Property  except
in  connection  with the full and complete  repayment  and  satisfaction  of the
Debentures.

        3. NAN  hereby  agrees  to (a)  extend  the cure  period  under  Section
8(a)(ii) of each of the Debentures with respect to the Interest  Payment Default
(but not with respect to any other  interest  payment due under the  Debentures)
until November 30, 1997,  provided,  however,  that (i) such extension  shall be
automatically  terminated  upon the  occurrence of any other default or Event of
Default  under  either of the  Debentures,  the  Common  Stock  and  Convertible
Subordinated  Debenture  Purchase  Agreement,  dated as of August 13,  1996 (the
"Purchase  Agreement"),  or this agreement,  and (ii) the amount of the Interest
Payment Default,  together with interest thereon calculated at an annual rate of
12.5% per  annum,  shall be  payable  upon the  expiration  of such cure  period
extension,  (b)  waive  the  Property  Sale  Default  by the  Company  under the
Debentures,  (c)  release of the  Mortgage  by  delivery  to the  Company of the
Quitclaim  Deed,  and (d) the partial  prepayment  of one of the  Debentures  in
accordance with the terms of this agreement.

         4. In consideration of NAN's aforesaid agreement, the Company agrees as
follows:

              (a)  Concurrently  with the closing of the  Property's  sale,  the
Company  shall  pay to NAN all of the net  sales  proceeds  from the sale of the
Property  (the gross  sales  proceeds  less a  $1,750,000  payment  to  Congress
Financial  Corporation in satisfaction of its first mortgage on the Property,  a
6% brokerage  commission and transfer taxes and legal fees actually  incurred in





connection with the sale), provided that (i) the net sales proceeds so delivered
to NAN shall be in an amount not less than  $883,000 (the  "Proceeds  Payment"),
and (ii) the Proceeds  Payment shall be received by NAN no later than by October
1, 1997. The Proceeds Payment shall be made concurrently with the closing of the
sale of the Property by means of a wire  transfer or transfers of same day funds
to an  account or  accounts  specified  in writing by NAN to the  Company or its
representatives.

              (b)  The  Proceeds  Payment  shall  be  treated  as if it  were  a
prepayment under Section 4(b) of the Debenture in the original  principal amount
of  $1,591,850  (the  "Prepaid  Indenture"),  and  accordingly,  only 80% of the
Proceeds  Payment shall be applied to the reduction of the principal  amount due
under the Prepaid Debenture,  with the balance to be deemed a prepayment premium
pursuant to Section 4(b) of such Prepaid Indenture.

              (c) Any land not  currently  being sold by Nantucket  shall remain
encumbered by the Mortgage.

        5. On or before  October 31, 1997,  the Company shall cause its Board of
Directors to be  reconstituted  to include the following  members:  Mr.  Stephen
Samberg,  Mr. Robert Rosen,  Mr. Warren Cole, Mr,  Kenneth Klein,  and two other
members who shall be satisfactory to NAN in NAN's sole  discretion.  The Company
shall be entitled to add Mr. Richard Ryan, or another person  unaffiliated  with
the  Company or its  shareholders  with  standing in the  business or  financial
communities, as an additional Board member.

        6.  Following  October  31,  1997,  the Company  shall  employ only such
executive  officers  (defined as officers  earning an annual  salary or draws on
account of  commissions in excess of $100,000),  other than the Chief  Executive
Officer,  as shall be reasonably  satisfactory to NAN. In addition,  the Company
shall, by October 31, 1997, cause another person or persons, satisfactory to NAN
in NAN's sole discretion (the "Manager"),  to become the chief operating officer
of the  Company  and an  authorized  signatory  on  all  of the  Company's  bank
accounts.  All withdrawals  from the Company's bank accounts and all agreements,
obligations or instruments to which the Company shall become a party or by which
any of its assets  shall be bound  following  the  Manager's  appointment  shall
require the signature of both the Chief Executive Officer of the Company and the
Manager.

        7. Within 5 days of resolution or settlement of its  litigation  against
Levi's and receipt of any payment  therefrom (the "Trigger  Date"),  the Company
shall offer to prepay all or any portion of the amounts then  outstanding  under
the  Debentures  at a price  equal  to 125% of the  aggregate  principal  amount
thereof,  together  with any  interest  accrued  and  unpaid  thereon  up to and
including the prepayment date. At the Company's  option,  up to $500,000 of such
amount may be payable in the form of a seven-year  debenture on terms  otherwise
substantially  equivalent  to those of the  Debentures,  with the  balance to be
payable in cash. The  provisions of Section 4(b) of the Debentures  shall apply,
mutatis  mutandis,  to such offer and  prepayment  (with the Trigger  Date to be
treated as a Change of Control under such Section).

        8.  The  Company  acknowledges  the  indebtedness   represented  by  the
Debentures  and  confirms  that the Company has no claims or rights of action of
any kind against NAN, NAN (GP) Investors, L.P., Fundamental Capital Corp.
or any of their respective officers, directors, partners or shareholders.

        9. The  Company  acknowledges  that NAN's  consent  to the  arrangements
herein shall not be construed as NAN's  agreement to any  amendment of the terms
of the Debentures or the Purchase  Agreement,  a waiver by NAN of any default by
the Company under the  Debentures  (other than the Property Sale Default) or the
Purchase  Agreement,  or a waiver  by NAN of any other of its  rights  under the
Debentures or under the Purchase Agreement.
