                  Each of the Unitholders hereby represents and warrants,
severally and not jointly, to the Company and Berkshire as follows:

                  Section 3.1 AUTHORITY RELATIVE TO THIS AGREEMENT. Such
Unitholder has all necessary power and authority to execute and deliver this
Agreement, to perform its obligations hereunder and to consummate the
transactions contemplated hereby. Where such Unitholder is a corporation,
partnership or other entity, the execution and delivery of this Agreement by
such Unitholder and the consummation by such Unitholder of the transactions
contemplated hereby have been duly and validly authorized by the board of
directors or other governing body of such Unitholder, and no other proceedings
on the part of such Unitholder are necessary to authorize this Agreement or to
consummate such transactions. This Agreement has been duly and validly executed
and delivered by such Unitholder and constitutes a legal, valid and binding
obligation of such Unitholder, enforceable against such Unitholder in accordance
with its terms, except to the extent enforceability may be limited by
bankruptcy, insolvency, moratorium or other similar laws affecting creditors'
rights generally or by general principles governing the availability of
equitable remedies.

                  Section 3.2 NO CONFLICT. (a) The execution and delivery of
this Agreement by such Unitholder does not, and the performance of this
Agreement by such Unitholder shall not, (i) where such Unitholder is a
corporation, partnership or other entity, conflict with or violate the
organizational documents of such Unitholder, (ii) conflict with or violate any
agreement, arrangement, law, rule, regulation, order, judgment or decree to
which such Unitholder is a party or by which such Unitholder (or the Units held
of record or Beneficially Owned by such Unitholder) is bound or affected or
(iii) result in any breach of or constitute a default (or an event that with
notice or lapse or time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, or result
in the creation of a lien or encumbrance on any of the Units held of record or
Beneficially Owned by such Unitholder pursuant to any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which such Unitholder is a party or by which such
Unitholder (or the Units held of record or Beneficially Owned by such
Unitholder) is bound or affected, except, in the case of clauses (ii) and (iii)
of this Section 3.2, for any such conflicts, violations, breaches, defaults or
other occurrences which would not prevent the performance by such Unitholder of
its material obligations under this Agreement.

                           (b)      The execution and delivery of this Agreement
by such Unitholder does not, and the performance of this Agreement by such
Unitholder shall





                                                                               4



not, require any consent, approval, authorization or permit of, or filing with
or notification to, any governmental entity except for applicable requirements,
if any, of federal or state securities and antitrust laws and except where the
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not prevent the performance by such
Unitholder of its material obligations under this Agreement.

                  Section 3.3 TITLE TO THE UNITS. As of the date hereof, such
Unitholder is the record or Beneficial Owner of the Units listed opposite the
name of such Unitholder on Schedule I hereto. The Units listed opposite the name
of such Unitholder on Schedule I hereto are all the securities of the
Partnership either held of record or Beneficially Owned by such Unitholder. Such
Unitholder has not appointed or granted any proxy, which appointment or grant is
still effective, with respect to the Units held of record or Beneficially Owned
by such Unitholder. The Units listed opposite the name of such Unitholder on
Schedule I hereto are owned free and clear of all security interests, liens,
claims, pledges, options, rights of first refusal, limitations on such
Unitholder's voting rights, charges and other encumbrances of any nature
whatsoever other than liens under applicable law.

                                   ARTICLE IV

                           COVENANTS OF THE UNITHOLDER

                  Section 4.1 NO INCONSISTENT AGREEMENTS. Each Unitholder hereby
represents, warrants, covenants and agrees that, except as contemplated by this
Agreement and the Investment Agreement, such Unitholder has not and shall not,
and will use its reasonable best efforts to not permit any Person under such
Unitholder's control to, enter into any voting agreement or grant a proxy or
power of attorney with respect to the Units held of record or Beneficially Owned
by such Unitholder which, in either case, is inconsistent with this Agreement.

                  Section 4.2 TRANSFER OF TITLE. Each Unitholder hereby
covenants and agrees that such Unitholder will not, prior to the termination of
this Agreement, either directly or indirectly, offer or otherwise agree to sell,
assign, pledge, hypothecate, transfer, exchange, or dispose of any Units or
options, warrants or other convertible securities to acquire or purchase units
of the Partnership or any other securities or rights convertible into or
exchangeable for units of the Partnership, owned either directly or indirectly
by such Unitholder or with respect to which such Unitholder has the power of
disposition, whether now or hereafter acquired, without the prior written
consent of the Company and Berkshire. Each Unitholder hereby agrees and consents
to the entry of stop transfer instructions by the Partnership against the
transfer of any Units inconsistent with the terms of this Section 4.2.







                                                                               5

hereunder; PROVIDED, HOWEVER, that nothing in this Agreement shall relieve any
party from liability for the breach of any of its representations, warranties,
covenants and agreements set forth in this Agreement prior to such termination.

                  Section 5.2 ADDITIONAL UNITS. If, after the date hereof, a
Unitholder acquires the right to vote any additional partnership interests of
the Partnership (any such partnership interests shall be referred to herein as
"ADDITIONAL UNITS"), the provisions of this Agreement applicable to the Units
shall be applicable to such Additional Units as if such Additional Units had
been Units held by the Unitholders as of the date hereof. The provisions of the
immediately preceding sentence shall be effective with respect to Additional
Units without action by any Person immediately upon the acquisition by a
Unitholder of the right to vote such Additional Units.

                  Section 5.3 SPECIFIC PERFORMANCE. The parties hereto agree
that irreparable damage would occur in the event any provision of this Agreement
was not performed in accordance with the terms hereof and that the parties shall
be entitled to specific performance of the terms hereof, in addition to any
other remedy at law or in equity.

                  Section 5.4 ENTIRE AGREEMENT. This Agreement and the

Company and the Unitholders with respect to the subject matter hereof and
supersedes all prior agreements and understandings, both written and oral,
between Berkshire, the Company and the Unitholders with respect to the subject
matter hereof; PROVIDED that, to the extent not inconsistent with the terms
hereof, the Settlement Agreement and Release, dated as of July 17, 1995, among
Equity Resources and the parties named therein shall continue in full force and
effect.

                  Section 5.5 AMENDMENT. This Agreement may not be amended

law, or public policy, all other conditions and provisions of this Agreement

incapable of being enforced, the parties hereby shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as
