                THIS AGREEMENT (this "Agreement") is made and entered into as of
                                      ---------
November 9, 2001, by and between  ROBERT E. GAFF, JR.  ("Shareholder")  and THOR
                                                         -----------
INDUSTRIES, INC., a Delaware corporation (the "Company").
                                               -------


                                   BACKGROUND


        A.      Prior to the  date  hereof,  Shareholder  was a  shareholder  of
Keystone RV Company,  an Indiana  corporation ("Old  Keystone").  Pursuant to an
                                                -------------
Agreement  and  Plan of  Merger  dated  as of  November  9,  2001  (the  "Merger
                                                                          ------
Agreement"),  by and among the  Company,  Thor  Acquisition  Corp.,  a  Delaware
- ---------
corporation  ("Acquisition   Subsidiary"),   Old  Keystone  and  certain  former
               ------------------------
securityholders  (including the  Shareholder) of Old Keystone,  Old Keystone was
merged with and into Acquisition Subsidiary,  with Acquisition Subsidiary as the
surviving corporation of the merger, and, accordingly, the corporation surviving
the merger ("Keystone") is now a wholly-owned subsidiary of the Company.
             --------

        B.      As a shareholder of Old Keystone, Shareholder made a significant
contribution to the growth, profitability and financial strength of Old Keystone
and,  as  a  shareholder  of  Old  Keystone,  Shareholder  received  substantial
consideration consisting of cash and common stock of the Company pursuant to the
Merger Agreement.

        C.      Shareholder  acknowledges  that he is aware of the  Business (as
defined below) in which the Company is engaged,  which includes the  manufacture
and  marketing  by Keystone of travel  trailers  and fifth wheel  vehicles;  and
Shareholder further  acknowledges that the business of Keystone is and will be a
material and significant  part of the Business;  that  Shareholder is one of the
very limited  number of persons who have  developed  the business of Keystone to
its  present  condition  and who are  capable  of  carrying  out a  business  in
competition  with the  Business;  that the  Business  is  national in scope (and
including  Canada);  that  Shareholder's  work with  respect to the Business has
brought  him  and,  if  Shareholder  should  become  employed  by,  or  become a
consultant  to, the Company or any of its  subsidiaries,  will continue to bring
him,  into close  contact with  proprietary  and  confidential  information  and
affairs of the Company and its subsidiaries that is not readily available to the
public; and that the Company will suffer substantial and irreparable harm in the
event  Shareholder   should  enter  into  competition  with,  or  give  material
assistance  of any kind to any third  party that is in or proposes to enter into
competition  with,  the  Company  or any of its  subsidiaries,  or in the  event
Shareholder  should disclose any of the proprietary or confidential  information
or affairs of the Company or any of its subsidiaries to any third party.

        D.      Accordingly, and as a substantial and material inducement to the
Company and  Acquisition  Subsidiary to enter into and perform their  respective
obligations under the Merger Agreement, Shareholder has agreed to enter into and

                                       1


perform his  obligations  under this  Agreement,  it being  understood  that the
Company and  Acquisition  Subsidiary  would not have  entered  into or performed
their  respective  obligations  under the Merger  Agreement  unless  Shareholder
entered into and agreed to perform his obligations under this Agreement.

                NOW,  THEREFORE,  in consideration of the foregoing premises and
for good, valuable and substantial consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto agree as follows:

on the date hereof and continuing until the fifth (5th)  anniversary of the date
hereof, he will not, directly or indirectly:

        however, that the foregoing shall not preclude (x) equity investments by
        -------
        Shareholder in publicly traded  companies in which  Shareholder does not
        own more than one percent  (1%) of the  outstanding  equity and does not
        actively participate in the business in which such investment is made or
        (y)  investments  by Shareholder  in  publicly-traded  securities of the
        Company);

                        (b)     interfere with,  disrupt, or attempt to disrupt,
        any  present or  prospective  relationship,  contractual  or  otherwise,
        between the Company or any of its subsidiaries  (including Keystone) and

                                       2


        any  vendor,  supplier,   dealer,   distributor,   customer,   employee,
        consultant or other person having business  dealings with the Company or
        any of its subsidiaries (including Keystone); or

                        (c)     employ or solicit the  employment  or engagement

        Keystone), other than any such persons who are not key employees and who
        respond to general  solicitations  for employment placed in publications
        of general distribution.

                1.3     Reasonableness.   Shareholder   acknowledges   that  the
                        --------------
restricted  period of time and  geographical  area and scope of the restrictions
under Section 1.2 hereof are  reasonable,  in view of the nature of the business
in  which  the  Company  and its  subsidiaries  are  engaged  and  Shareholder's
knowledge  of the  Company's  business,  and the  fact  that  Shareholder,  as a
shareholder of Old Keystone, has received substantial  consideration  consisting
of cash and common stock of the Company pursuant to the Merger Agreement.

        2.      Nondisclosure.
                -------------

                Except  with the prior  written  consent of the  Company in each
instance or, if  Shareholder  should become  employed by, or become a consultant
to,  the  Company or any of its  subsidiaries,  as may be  necessary  to perform
services on behalf of the  Company or its  subsidiaries,  Shareholder  shall not
disclose,  use, publish, or in any other manner reveal,  directly or indirectly,
at any  time  during  or  after  the term of this  Agreement,  any  confidential
information  relating  to the Company or any  subsidiary  or  affiliate  thereof
acquired  by him prior to the date  hereof or during the course of, or  incident
to, any services  Shareholder  hereafter may perform on behalf of the Company or
any of its subsidiaries.  Such confidential information shall include, but shall
not be  limited  to,  information  relating  to (a)  the  business,  operations,
systems,  services,  know-how, trade secrets,  customer lists, pricing policies,
operational methods, market plans, product development plans, acquisition plans,
products and product ideas, design and design projects,  inventions and research
projects  and  all  other  plans  and  processes  of the  Company  or any of its
subsidiaries, and (b) the business, operations, personnel, activities, financial
affairs,   and  other  information  relating  to  the  Company  or  any  of  its
subsidiaries  and its  vendors,  suppliers,  dealers,  distributors,  customers,
employees,  consultants,  officers,  directors,  stockholders  and other persons
having  business  dealings with the Company or any of its  subsidiaries.  In the
event Shareholder is required (by oral questions, interrogatories,  requests for
information or documents in legal proceedings,  subpoenas,  civil  investigative
demand or  similar  process)  to  disclose  any such  confidential  information,
Shareholder  shall  provide  the  Company  with  prompt  written  notice of such
requirement so that the Company may seek a protective order or other appropriate
remedy and/or waive  compliance with the provisions of this Section.  If, in the
absence of such a protective order or other remedy or receipt of a waiver by the
Company,  Shareholder  is  nonetheless  advised by his legal  counsel that he is
legally  compelled to disclose such confidential  information,  Shareholder may,
without  liability  hereunder,  disclose only that portion of such  confidential
information  which such  counsel  advises is legally  required to be  disclosed,
provided  that the  Shareholder  exercises  his best  efforts  to  preserve  the

                                       3


confidentiality  of  the  information,   including,   without   limitation,   by
cooperating, at the Company's expense, with the Company to obtain an appropriate
protective order or other reliable assurance that confidential treatment will be
accorded the confidential information.

        3.      Proprietary Information.
                -----------------------

                Shareholder  shall promptly disclose to the Company in such form
and manner as the Company may reasonably  require (a) all  operations,  systems,
services,   methods,   developments,   inventions,   products,   product  ideas,
improvements  and  other  information  or data  pertaining  to the  business  or
activities of the Company or its  subsidiaries  (which shall include,  for these
purposes,  Keystone  and Old  Keystone)  as  have  been  conceived,  originated,
discovered or developed by Shareholder  (whether or not  copyrighted or patented
or capable of being  copyrighted  or patented)  prior to the date hereof and, if
Shareholder  should remain employed with, or become a consultant to, the Company
or any of its subsidiaries, during the term of any such employment or consulting
arrangement,  and (b) such  information  and data  pertaining  to the  business,
operations,  personnel,  activities,  financial  affairs,  and other information
relating to the Company or any of its subsidiaries  and its vendors,  suppliers,
dealers,  distributors,  customers,  employees,  consultants  and other  persons
having business  dealings with the Company or any of its  subsidiaries as may be
reasonably  required for the Company or any of its  subsidiaries  to operate its
business.  It is understood  that such  information is proprietary in nature and
shall (as  between the Company and  Shareholder)  be for the  exclusive  use and
benefit of the  Company or any of its  subsidiaries  and shall be and remain the
property  of the  Company or any of its  subsidiaries.  If so  requested  by the
Company,  Shareholder  shall  execute  and  deliver to the Company or any of its
subsidiaries any instrument as the Company may reasonably  request to effectuate
the assignment of any such proprietary  information to the Company or any of its
subsidiaries.  At any  time,  and from  time to time,  upon the  request  of the
Company,  Shareholder  shall  deliver to the Company  (and shall not keep in his
possession,  recreate or deliver to anyone  other than the  Company) any and all
devices,  records,  data,  notes,  reports,  proposals,  lists,  correspondence,
specifications,  drawings,  blueprints,  sketches,  materials,  equipment, other
documents  or property,  together  with all copies  thereof (in whatever  medium
recorded) relating to such proprietary  information and belonging to the Company
or any of its subsidiaries or their respective successors or assigns.

        4.      Enforcement; "Blue-Pencil" Authorization.
                ----------------------------------------

                Shareholder intends to, and does hereby,  confer jurisdiction to
enforce the  covenants  contained in this  Agreement  upon the courts of (i) any
jurisdiction within the State of Indiana or (ii) if Shareholder is alleged to be
committing,  or threatening  to commit,  a breach of this Agreement in any other
jurisdiction, then in any other jurisdiction in which such alleged breach takes,
or is threatened to take,  place.  If any provision of this Agreement is held to
be unenforceable  because of the duration thereof or the area covered thereby or
the scope  thereof,  or  otherwise,  the parties agree that the court making the
determination shall have the power to reduce the duration and/or the area and/or
the scope of such provision,  or to delete specific words or phrases, and in its
reduced form such  provision  shall then be  enforceable  and be enforced to the
fullest  extent  permitted  by  law.  If the  courts  of any one or more of such
jurisdictions shall hold such covenants wholly unenforceable against Shareholder
by reason of the duration  thereof  and/or the area covered  thereby  and/or the
scope  thereof,  or otherwise,  such  determination  shall not bar or in any way

                                       4


affect the right of the Company to the relief  provided  herein in the courts of
any other  jurisdiction  in which such  covenants  may be  enforced  as provided
herein, as to breaches of such covenants in such other respective jurisdictions,
the above covenants as they relate to each jurisdiction being, for this purpose,
severable  into  diverse  and  independent  covenants  and,  further,  any  such
determination  shall not bar or in any way  affect  the right of the  Company to
enforce any of the  covenants  or similar  covenants  by which any other  former
securityholder  of Old  Keystone  is subject  pursuant to the terms of any other
non-competition  agreement entered into in connection with the Merger Agreement.
It is the intention of the parties  hereto that the covenants  contained in this
Agreement  shall at all times be enforceable to the fullest extent  permitted by
law, and that any court making the  determination as to the enforceablity of any
such covenants be authorized as provided  herein to enforce this  Agreement,  or
such part hereof, in order to effectuate the intention of the parties,  it being
agreed that the compliance by Shareholder  with the covenants  contained in this
Agreement was a substantial and material inducement to the Company's decision to
enter  into  the  Merger  Agreement  and to  pay  substantial  consideration  to
Shareholder pursuant to the Merger Agreement.

        5.      Remedies for Certain Breaches.
                -----------------------------

                If  Shareholder  commits  a  breach,  or  threatens  to commit a
breach,  of any of the provisions of this Agreement,  the Company shall have the
following  rights  and  remedies,  each of which  rights and  remedies  shall be
independent of the others, and shall be severally enforceable,  and all of which
rights  and  remedies  shall be in  addition  to,  and not in lieu of, any other
rights and remedies available under law or in equity to the Company:

                        (a)     the right and remedy to have the  provisions  of
        this  Agreement  enforced  by any  court of  competent  jurisdiction  by
        injunction,  restraining order,  specific performance or other equitable
        relief  in favor of the  Company  or any of its  subsidiaries,  it being
        acknowledged  and agreed  that any breach or  threatened  breach of this
        Agreement by Shareholder  will cause  irreparable  injury to the Company
        and that  money  damages  will not  provide  an  adequate  remedy to the
        Company; and

                        (b)     the right and remedy to require  Shareholder  to
        account  for and pay  over to the  Company  all  compensation,  profits,
        monies,   accruals,   increments   or  other   benefits   (collectively,
        "Benefits")  derived or  received  by  Shareholder  as the result of any
        transaction  constituting  a  breach  of any of the  provisions  of this
        Agreement and Shareholder  hereby agrees to account  accurately for such
        Benefits and pay over all such Benefits to the Company.

        6.      Absence of Restrictions.
                -----------------------

                No provision of this  Agreement  shall be deemed to restrict the
absolute  right of the Company at any time to sell or dispose of all or any part
of the assets of the  Company,  or to  reconstitute  the same in any one or more
other entities, or to merge, consolidate, sell or liquidate or otherwise abandon
or cease the active conduct of its or any of its subsidiaries' business.

                        ----------------
Merger Agreement,  constitutes the entire agreement between  Shareholder and the
Company  with  respect to the subject  matter  hereof and  supersedes  all prior
agreements  and  understandings,  written or oral,  with  respect to the subject
matter hereof.

                8.2     Amendments and Waivers.   Any term of this Agreement may
                        ----------------------
be  amended  and the  observance  of any term of this  Agreement  may be  waived
(either  generally  or in a  particular  instance  and either  retroactively  or
prospectively), only by an instrument in writing and signed by the party against

                                       6


whom such  amendment  or waiver is  sought  to be  enforced.  The  waiver by the
Company of a breach of any provision of this  Agreement  shall not operate or be
construed as a further or continuing waiver of such breach or as a waiver of any
other or subsequent  breach.  No failure on the part of the Company to exercise,
and no delay in exercising,  any right,  power or remedy hereunder shall operate
as a waiver  thereof,  nor shall any single or partial  exercise  of such right,

or the exercise of any other right, power or remedy.

        8.3     Successors and Assigns.   The  Company  shall  have the right to
                ----------------------

and the rights and obligations of the parties hereunder,  and all amendments and
supplements hereof and all waivers and consents hereunder, shall be construed in
accordance  with and governed by the domestic  substantive  laws of the State of
Indiana without giving effect to any choice of law or conflicts of law provision
or rule that would cause the application of the domestic substantive laws of any
other jurisdiction.

        8.5     Severability.   If any  provisions of this  Agreement as applied
                ------------
