ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On September 27, 1995, Centex International, Inc., a Nevada
corporation ("Centex International"), a wholly owned subsidiary of Centex
Corporation, a Nevada corporation ("Centex"), completed the acquisition of
equity securities of Vista Properties, Inc., a Nevada corporation ("Vista"), in
accordance with the terms of a Second Amended and Restated Securities Purchase
Agreement, as amended, among Centex International, Vista, and the other parties
named therein.  Upon the consummation of the acquisition, Centex International
owned a majority of the equity securities of Vista.  At the time of the
acquisition, Vista, through its wholly owned subsidiaries and through Vista
Partners, its wholly owned partnership, owned approximately 3,500 acres of land
in seven states.  The land is zoned, planned or developed for single- and
multi-family residential, office and industrial, and retail and commercial
uses.  Unless the context requires otherwise, the term "Vista" as used herein
shall mean Vista Properties, its subsidiaries, and Vista Partners.

         The equity interests were acquired for approximately $115 million,
which included a net investment of approximately $85 million by Centex
International and approximately $30 million of Vista's cash balances and
securities.  Centex International received shares of Vista's Common Stock,
Series A Preferred Stock, and Series B Preferred Stock which were issued by
Vista as a part of a "prepackaged" Chapter 11 bankruptcy filed by Vista on
August 17, 1995.

         To fund the payment of the purchase price, Centex, on behalf of Centex
International, used funds provided by (i) the issuance of Centex's commercial
paper and (ii) short-term bank borrowings under existing unsecured credit
facilities from a combination of the following commercial banks:  Bank of
America, National Westminster Bank, Societe General, Sumitomo Bank, and Texas
Commerce Bank.

         In arriving at the purchase price paid by Centex International for the
equity interests in Vista, Centex International calculated a range of values
for Vista's assets after a substantial due diligence review of the assets by
Centex personnel.  After arm's-length negotiations, Centex International,
Vista, and certain of Vista's subsidiaries entered into a definitive purchase
agreement, subject to certain overbid procedures.  Centex International
subsequently increased its bid in response to bids and expressions of interest
by competing acquirers.

ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS.

         (a)     Financial Statements of Businesses Acquired.

                          In accordance with Item 7(a)(4) of Form 8-K, because
                 it is impracticable for the registrant to provide the required
                 financial statements for the acquired business at the time of
                 filing of this Current Report on Form 8-K, the registrant will
                 file an amendment to this Report to supply such financial
                 statements as soon as practicable, but not later than December
                 11, 1995.

of which the Company is the common parent).  No Employee Benefit Plans cover
persons employed outside of the United States.  No Employee Benefit Plans are
subject to Section 4063 or 4064 of ERISA.  No Employee Benefit Plans are
"multiemployer plans" as defined in Section 3(37) of ERISA (collectively, the
"Multiemployer Plans").  No Employee Benefit Plans that are welfare plans as
defined in Section 3(1) of ERISA provide benefits after termination of
employment (other than as required by Section 4980B of the Internal Revenue
Code and at the former employee's own expense).  No Employee Benefit Plan is a
"defined benefit plan" as defined in Section 3(35) of ERISA, or a "pension
plan" as defined in Section 3(2) of ERISA.

             (b)     Each of the Employee Benefit Plans intended to qualify
under Section 401 of the Internal Revenue Code (collectively, the "Qualified
Plans") so qualifies, and nothing has occurred with respect to the operation of
any such plan which could cause the loss of such qualification or the
imposition of any material liability, penalty or tax under ERISA or the
Internal Revenue Code.  Any entity maintained or contributed to by the Company
or any Subsidiary and which is intended to be an association described in
Section 501(c)(9) of the Internal Revenue Code is exempt from federal income
Tax under Section 501(a) of the Internal Revenue Code.

             (c)     To the knowledge of the Vista Parties, all contributions
and premiums required by law or by the terms of each Employee Benefit Plan or
any agreement relating thereto have been timely made (without regard to any
waivers granted with respect thereto).

             (d)     There has been no "reportable event," as that term is
defined in Section 4043 of ERISA and the regulations thereunder, with respect
to any of the Qualified Plans which would require the giving of notice, or any
event requiring notice to be provided, under Section 4063(a) of ERISA.

             (e)     There has been no violation of ERISA that could result in
a material liability with respect to the filing of applicable returns, reports,
documents or notices regarding any of the Employee Benefit Plans with the
Secretary of Labor or the Secretary of the Treasury or the furnishing of such
notices or documents to the participants or beneficiaries of the Employee
Benefit Plans.

             (f)     Except as set forth on Schedule 3.20(f), true and complete
copies of the following documents with respect to each of the Employee Benefit
Plans (as applicable) have been delivered by the Company to the Purchaser:  (i)
any plans and related trust documents, and all amendments thereto, (ii) the
most recent Forms 5500 and schedules thereto, (iii) any determination letters
or applications therefor, (iv) the most recent summary plan description, and
(v) written descriptions of all non-written agreements relating to the Employee
Benefit Plans.

             (g)     There are no pending actions, suits or proceedings which
have been asserted, instituted or overtly threatened against any Employee
Benefit Plan, the assets of any such plan or the Company, or the plan
administrator or fiduciary of any Employee Benefit Plan with respect to the
operation of any such plan (other than routine, uncontested benefit claims),
and there are no facts or circumstances which could reasonably be expected to
form the basis for any such action, suit or proceeding.  Neither the Company
nor any Subsidiary nor any fiduciary of any plan which is not a Multiemployer
Plan has engaged in a nonexempt prohibited transaction described in Sections
406 of ERISA or 4975 of the Internal Revenue Code.

             (h)     Each of the Employee Benefit Plans has been maintained and
administered, in all material respects, in accordance with its terms and all
provisions of applicable Legal Requirements.  All amendments and actions
required to bring each of the Employee Benefit Plans into conformity with all
of the applicable provisions of ERISA and other applicable Legal Requirements
have been made or taken except to the extent that such amendments or actions
are not required by law to be made or taken until a date after the Closing Date
and are disclosed on Schedule 3.20(h).

             (i)     Each Employee Benefit Plan complies in all material
respects with all applicable requirements of (i) the Age Discrimination in
Employment Act of 1967, as amended, and the regulations thereunder; (ii) Title
VII of the Civil Rights Act of 1964, as amended, and the regulations
thereunder; (iii) the health care continuation provisions of COBRA; and (iv)
the Medicare Secondary Payor Provisions of Section 1862(b) of the Social
Security Act.

             (j)     Except as set forth on Schedule 3.20(j), the Company is
not a party to any agreement, contract or arrangement that would result in the
payment of any "excess parachute payments" within the meaning of Section 280G
of the Internal Revenue Code.

             (k)     Except as set forth in Schedule 3.20(k) hereto, the
Company will not have, by reason of the transactions contemplated by this
Agreement, any obligation to make any payment to any employee pursuant to any
Employee Benefit Plan.

             SECTION 3.21.    Labor Matters.  Except as set forth on Schedule
3.21 hereto, (i) neither the Company nor any Subsidiary is a party to any
collective bargaining agreement or other labor union contract applicable to
persons employed by them nor do the Vista Parties know of any activities or
proceedings of any labor union to organize any such employees and (ii) there
are no unfair labor practice complaints pending against the Company or any
Subsidiary before the National Labor Relations Board.

             SECTION 3.22.    Permits.  Except as set forth in Schedule 3.22
hereto, the Company and its Subsidiaries own or validly hold all licenses,
franchises, permits, approvals, authorizations, exemptions, classifications,
certificates, registrations and similar documents or instruments (collectively,
"Permits") that are required in connection with the conduct of their respective
businesses, including, but not limited to, Permits





                                     -27-

<PAGE>   33





required under Environmental Laws, except in cases where the failure to own or
hold such Permits could not reasonably be expected to have a Material Adverse
Effect.  All Permits owned or held by the Company or any Subsidiary are valid
and in full force and effect.  No proceeding is pending or overtly threatened
which could result in the revocation or termination of any such Permits, and
the Vista Parties know of no basis on which any such proceeding could be
commenced.  The consummation of the transactions contemplated by this Agreement
will not affect the continued validity, effectiveness or terms and conditions
of all Permits owned or held by the Company.

             SECTION 3.23.    Insurance.  Schedule 3.23 sets forth true and
correct summaries of all liability and other insurance policies maintained by
the Company and its Subsidiaries, and accurately states the coverages,
deductible amounts and carriers of each such insurance policy.  All such
insurance policies are in full force and effect and no notice of cancellation
or termination has been received with respect to any such policy.  All such
insurance policies are maintained with reputable and, to the knowledge of the
Vista Parties, financially sound insurance companies and associations.  There
are no circumstances known to the Vista Parties that would enable any insurance
company or association to avoid liability under any of the insurance policies
maintained by the Company or any Subsidiary, other than pursuant to express
exclusions and limitations of such policies.  The coverage provided by such
insurance policies with respect to events occurring prior to the Closing Date
will not be affected in any manner by, and will not terminate or lapse by
reason of, any of the transactions contemplated by this Agreement.  At no time
since January 31, 1992 has any insurance company or association cancelled or
reduced any coverage maintained by the Company or any Subsidiary, or given any
notice or other indication of its intention to cancel or reduce any such
coverage.  The loss, damage or destruction of any properties and assets of the
Company or its Subsidiaries which are not fully covered by insurance would not
have a Material Adverse Effect.

             SECTION 3.24.    Transactions with Affiliates.  Except as set
forth in Schedule 3.24 hereto, since June 30, 1994, neither the Company nor any
Subsidiary has purchased, acquired or leased any property or services from, or
sold, transferred or leased any property or services to, or loaned or advanced
any money to, or borrowed any money from, or guaranteed or otherwise become
liable for any indebtedness or other obligations of, or acquired any capital
stock, obligations or securities of, or made any management, consulting or
similar fee arrangement with, or entered into or consummated any other material
transaction, agreement or arrangement with or for the benefit of, any officer,
director or employee of the Company or any of its Affiliates, other than (i)
compensation and benefits (including travel advances) provided to any such
officer, director or employee in the ordinary course of business and consistent
with past practice and (ii) any such transactions between or among the Company
and its direct or indirect wholly owned Subsidiaries.

             SECTION 3.25.    Absence of Certain Business Practices.  Neither
the Company nor any of its Affiliates, directors, officers, employees or agents
has, directly or indirectly, given or agreed to give any gift or similar
benefit to any property developer, supplier, competitor or governmental
employee or official (domestic or foreign) which could reasonably be expected
to subject the Company to any damage or penalty in any civil, criminal or
governmental litigation or proceeding.

             SECTION 3.26.    Disclosure.  The representations and warranties
by the Vista Parties contained in this Agreement, and the statements contained
in any Schedule required hereby or any other document, certificate or other
writing delivered or to be delivered by or on behalf of the Vista Parties
pursuant to the provisions of this Agreement or in connection with the
transactions contemplated hereby, when taken in their entirety, do not and will
not contain any untrue statement of a material fact, and do not and will not
omit to state any material fact required in order to make the statements
therein, in the light of the circumstances under which they were or will be
made, not misleading.

             SECTION 3.27.    Brokers' or Finders' Fees.  Except as set forth
in Schedule 3.27 hereto, no broker, finder or investment banker is entitled to
any brokerage or finder's fee or other fees or commissions in connection with
this Agreement or the transactions contemplated hereby based upon arrangements
made by or on behalf of any Vista Party.

                         REPRESENTATIONS AND WARRANTIES
                                OF THE PURCHASER

             The Purchaser hereby represents and warrants to the Vista Parties

duly incorporated, validly existing and in good standing under the laws of the
State of Nevada and has all requisite corporate power and authority to own,
lease and operate its properties and to carry on its business as presently
conducted.

             SECTION 4.02.    Authority; Binding Effect.  The Purchaser has all

hereunder and the consummation by it of the transactions contemplated hereby
will not (i) conflict with, or result in any violation or breach of, any

             SECTION 4.05.    Disclosure Statement.  Any information furnished
by the Purchaser in writing expressly for use in the Disclosure Statement, when

             SECTION 4.06.    Brokers' or Finders' Fees.  The Purchaser has not

                                   ARTICLE V.

                          REORGANIZATION SOLICITATION;

Disclosure Statement shall contain the recommendation of the Board of Directors

             (e)     Promptly after receipt of the Solicitation Materials, the

             SECTION 5.03.    Reorganization Proceedings.

             (a)     The Company shall use its reasonable best efforts to
obtain confirmation of the Reorganization Plan by the Bankruptcy Court using
the acceptances of the Reorganization Plan received by the Company pursuant to
the Reorganization Solicitation.

             (b)     The Company shall comply with the Bankruptcy Code and all

the Bankruptcy Court all motions, schedules, statements of financial affairs,
reports, and all other papers and filings required by the Bankruptcy Code and
all other applicable laws, rules, regulations, orders or decrees (the
"Bankruptcy Filings").  The Purchaser and its counsel shall be given a
reasonable opportunity to review and comment upon the Bankruptcy Filings prior
to the time they are filed with the Bankruptcy Court.

             (c)     The extent, method, and means of notice of the filing of
the Bankruptcy Case and meetings of creditors, hearings, objection dates, bar
dates for filing proofs of claims or interests, the hearing on approval of the
Reorganization Solicitation and the confirmation of the Bankruptcy Plan, and
other significant events in connection with the Bankruptcy Case, given to

receive any such notice, shall be decided by the Company in consultation with,
and subject to the approval of, the Purchaser.

             (d)     The Company shall use its reasonable best efforts to
obtain, and shall not take, or omit to take, any action the taking or omission
of which could reasonably be expected to prevent or impede, or result in the
revocation of, (i) the confirmation of the Reorganization Plan (as provided in
Section 1144 of the Bankruptcy Code), (ii) a full and complete discharge of all
debts of the Company (to the fullest extent possible under Section 1141(d) of
the Bankruptcy Code) except as otherwise specifically provided in the
Reorganization Plan and (iii) the vesting upon the entry of the Confirmation
Order of the property of the Company in the reorganized entity free and clear
of all claims and interests of creditors and equity security holders in
accordance with the Reorganization Plan.  To the extent that the Reorganization
Plan requires the Company to take any action in the Bankruptcy Case, including,
but not limited to, designating executory contracts to be assumed or rejected
and making elections concerning treatment of claims, the Company shall take
such action after consultation with and, in the case of any election to be
made, obtaining the approval of the Purchaser.

             (e)     The Reorganization Plan will be in the form attached as
Exhibit G hereto with such changes therein as shall be approved by the
Purchaser in its reasonable discretion.  Without limiting the generality of the
foregoing, the Reorganization Plan shall provide that the total payments and
distributions made to holders of Existing Securities under the Plan shall be
allocated among the holders of Existing Securities as provided in Appendix B
hereto.  The Company shall not consent to any amendment or supplement to, or
modification of, the Reorganization Plan or the Disclosure Statement that
purports to effect any change in the terms or conditions of the transactions
contemplated by this Agreement which is, in the reasonable judgment of the
Purchaser, unfavorable to it or any change in the manner in which the total
payments and distributions under the Reorganization Plan is allocated among the
holders of Existing Securities without the prior written consent of the
Purchaser.

             (f)     Notwithstanding anything to the contrary contained in this
Agreement, the parties agree that the claims identified in Appendix D hereto
shall be classified in the manner contemplated by, and shall receive the
treatment specified in, such appendix.

all filing and other requirements of the Exchange Act, and the rules and
regulations thereunder, and any other applicable federal or state securities
laws, rules or regulations in connection with the Reorganization Solicitation
and the consummation of the Reorganization Transactions.

                               CERTAIN COVENANTS

available the services of their present officers and employees and maintain
their present relationships with property developers, suppliers, insurers,
lessors and licensees and with the Governmental Authorities and other Persons
having business relationships with the Company or any Subsidiary.  Without
limiting the generality of the foregoing, from the date hereof until the
Closing Date, except as provided in this Agreement or the Reorganization Plan,

             (s)     fail to maintain the books and records of the Company or
any Subsidiary in the usual, regular and ordinary manner;

             (t)     make any Tax elections or settle or compromise any income
tax liability, except in the ordinary and regular course of business and
consistent with past practice; and

             (u)     take any action which would cause any representation or
warranty of the Vista Parties contained in this Agreement to be untrue or
incorrect as of the date when made or (except in the case of representations
and warranties made as of a specific date) as of any future date.

             SECTION 6.02.    Other Proposals.

             (a)     From the date hereof until the Closing Date, the Vista
Parties and the Subsidiaries shall not, and shall use their best efforts not to
permit their respective Affiliates, directors, officers, agents or other
representatives (including, but not limited to, any investment banker,
financial advisor, attorney or accountant) to, initiate any contact with,
solicit, encourage or enter into or continue any negotiations, understandings
or agreements with any Third Party with respect to, or furnish or disclose any
non-public information regarding the Company or its Subsidiaries or their
respective businesses to any Third Party in connection with, any Acquisition
Proposal.  Notwithstanding the foregoing, to the extent required by the
fiduciary obligations of the Board of Directors of the





                                     -33-

Company based on the advice of counsel, (i) the Company may, in response to an
unsolicited request therefor, furnish non-public information with respect to
the Company or its Subsidiaries or their respective businesses to any Qualified
Third Party pursuant to a customary confidentiality agreement and discuss such
information (but not any Acquisition Proposal and not any non-public
information relating to the structure of the transactions contemplated hereby,
other than any information which the Company can demonstrate was independently
developed by it or its advisors) with such Qualified Third Party and (ii) upon
receipt by the Company of an Acquisition Proposal from a Qualified Third Party,
if (A) the Company has complied fully and in a timely manner with its
obligations to notify the Purchaser of the receipt of such Acquisition Proposal
(and the identity of the offeror and the material terms of such proposal) in
accordance with Section 6.02(b) hereof, (B) the Board of Directors of the
Company has reasonably determined that such Acquisition Proposal, if
consummated, would constitute an Overbid Transaction and (C) the Company has
delivered a written notice to the Purchaser (an "Overbid Notice") advising it
of the foregoing determination by the Board of Directors (which notice shall be
accompanied by copies of the form of definitive agreement or other
documentation proposed to be entered into in connection with the Acquisition
Proposal), the Company may participate in discussions and negotiations with
such Qualified Third Party regarding such Acquisition Proposal.  Furthermore,
if (v) the Company has delivered an Overbid Notice to the Purchaser (after
compliance in full with each of the conditions precedent to the delivery of
such a notice set forth in clauses (i) and (ii) of the immediately preceding
sentence), (w) the Purchaser shall not have delivered to the Company within ten
calendar days after receipt of such Overbid Notice a written offer (a "Topping
Offer") to amend the terms of this Agreement in order to provide for
consideration attributable to the Existing Securities having a value at least
$1,000,000 greater than the value of the consideration provided for under the
Acquisition Proposal to which such Overbid Notice relates, which offer shall
state that it may not be withdrawn or revoked by the Purchaser unless the
Company and the Purchaser do not enter into an amendment to this Agreement to
reflect the acceptance of the Topping Offer within ten calendar days after
receipt thereof by the Company (it being understood and agreed that, if the
Purchaser does deliver a Topping Offer to the Company, the Company shall
immediately cease to participate in discussions or negotiations with such
Qualified Third Party regarding such Acquisition Proposal), (x) the terms of
the Acquisition Proposal shall not have been modified in a manner adverse to
the Company or the holders of Existing Securities after the date of the Overbid
Notice (it being understood and agreed that the Company shall promptly advise
the Purchaser in writing of the nature of any change in the terms thereof), (y)
either the Company shall have paid the Termination Fee to the Purchaser (if the
Company shall not have theretofore delivered the Termination Fee to the
Termination Fee Escrow Agent) or the Vista Parties shall have taken all action
on their part required in order to cause the Termination Fee Escrow Agent to
deliver the Termination Fee Deposit to the Company (if the Company shall have
theretofore delivered the Termination Fee to the Termination Fee Escrow Agent)
and (z) the Vista Parties shall have taken all action on their part required to
cause the Earnest Money Escrow Agent to deliver the Earnest Money Deposit to
the Purchaser (the conditions set forth in clauses (v), (w), (x), (y) and (z)
above being hereinafter collectively referred to as the "Overbid Termination
Conditions"), the Company may enter into an agreement with a Qualified Third
Party with respect to an Overbid Transaction.  It is expressly understood and
agreed that, if any Affiliates, directors, officers, agents or other
representatives (including, but not limited to, any investment banker,
financial advisor, attorney or accountant) of the Company, whether or not such
persons are purporting to act on behalf of the Company, engage in any conduct
involving the furnishing of information to, the solicitation of, or
participation in discussions or negotiations with, a Third Party which, if
performed by the Company, would constitute a breach of the provisions of this
Section 6.02(a), then, notwithstanding anything to the contrary contained
herein, such Third Party shall not be deemed a Qualified Third Party for
purposes of this Agreement.

             (b)     In the event the Company shall directly or indirectly
receive any offer, proposal or inquiry regarding an Acquisition Proposal, the
Company shall notify the Purchaser within one Business Day after the receipt of
such offer, proposal or inquiry and shall, in any such notice to the Purchaser,
indicate the identity of the offeror and all of the material terms of such
offer, proposal or inquiry.

             (c)     The Company shall not modify, or release any Third Party
from any confidentiality or standstill agreement to which the Company is a
party (exclusive of those in which the Company is solely the recipient rather
than the provider of confidential information).

             SECTION 6.03.    Access to Information.  From the date hereof
until the Closing Date, the Company shall permit the Purchaser, and its
Affiliates, directors, officers, agents or other representatives (including,
but not limited to, any attorney or environmental consulting firm) to make a
full investigation of the business, prospects, properties, financial condition
and results of operations of the Company and its Subsidiaries and will afford
the Purchaser and such representatives full access to the offices, buildings,
real properties, records, files, books of account, tax returns, agreements and
commitments, record books and stock books of the Company and its Subsidiaries
and to their directors, officers, independent accountants, agents and other
representatives, at such reasonable times and as often as the Purchaser may
reasonably request.  Upon request by the Purchaser, the Company shall request
their present and former independent accountants to afford the Purchaser and
its representatives access to all accountants' working papers for all audits
and reviews of the financial statements of the Company and its Subsidiaries.
The Company shall afford to the Purchaser and its representatives access to all
such further information relating to the business, prospects, properties,
financial condition and results of operations as the Purchaser or such
representatives may reasonably request.  No investigation pursuant to this
Section 6.03 shall affect any representations or warranties made by the Vista
Parties in this Agreement or the conditions to the obligations of any party
hereto to consummate the transactions contemplated hereby.  The provisions of
the Confidentiality Agreement shall apply to any information provided to the
Purchaser, or its Affiliates, directors, officers, agents or other
representatives, pursuant to this Section 6.03; provided, however, that as of
the Closing Date, the Confidentiality Agreement shall terminate and be of no
further force and effect.

             SECTION 6.04.    Best Efforts.  Subject to the terms and
conditions hereof, each of the parties hereto shall use its reasonable best
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things which are necessary, proper or advisable under applicable laws
and regulations or otherwise in order to consummate and make effective the
transactions contemplated by this Agreement.  Without limiting the generality
of the foregoing, each of the parties hereto shall execute and deliver, or
cause to be executed and delivered, all agreements, certificates and other
instruments and shall use its reasonable best efforts promptly to obtain all
waivers, permits, consents, approvals and other authorizations from, and to
effect all registrations, filings and notices with or to, any Governmental
Authorities or other Persons which are necessary or appropriate in connection
with said transactions or in order to fulfill all conditions to obligations of
the parties under this Agreement.

             SECTION 6.05.    HSR Act.  Each of the Company and the Purchaser
will promptly file or cause to be filed with the Antitrust Division of the
Department of Justice and the Federal Trade Commission notification and report
forms pursuant to the HSR Act relating to the transactions contemplated by this
Agreement.  The Company and the Purchaser shall promptly respond to any request
for additional information or documentary material by the Antitrust Division of
the Department of Justice or the Federal Trade Commission and will cooperate
with each other in order to ensure that any waiting period (and any extension
thereof) applicable to the consummation of the transactions contemplated by
this Agreement under the HSR Act expires or is terminated as soon as
practicable.

             SECTION 6.06.    Title Policies.  If the Purchaser so requests,
the Company shall obtain, at its expense, from one or more title companies
reasonably acceptable to the Purchaser and shall deliver to the Purchaser at
Closing, with respect to each lot, parcel and tract of land constituting the
Real Property, an Owner's Policy of Title Insurance or an endorsement to an
existing title insurance policy bringing coverage current to the Closing Date
in the form of an ALTA Form B Extended Coverage Owners Policy to the extent
available in the applicable state based on the most recent surveys of such lot,
parcel or tract delivered to the Purchaser and otherwise in a form which is
standard for the applicable state and provides substantially the same coverage
as the above mentioned ALTA policy (each a "Title Policy") in an amount
acceptable to the Purchaser.  The Title Policies shall insure to the Company
fee simple title to the Real Property in marketable or indefeasible condition
customary to the state in which the property is located, subject only to the
Permitted Encumbrances, including, in the case of the Real Property located in
Texas, the standard printed exceptions contained in Schedule B thereof;
provided, however, (A) the standard exception as to restrictive covenants shall
be deleted in its entirety (unless recorded restrictive covenants are specified
as or deemed to be Permitted Encumbrances, in which event the recording
information thereof shall be listed under such exception), (B) the standard
exception as to survey shall be limited to "shortages in area" only, (C) the
standard exception as to standby fees and taxes shall be limited to the current
year and subsequent years not yet due and payable and subsequent assessments
for prior years due to change in land usage or ownership, and (D) the standard
exception as to rights of parties in possession shall be limited to rights of
tenants in





                                     -35-

possession as tenants under any presently effective unrecorded leases.
Notwithstanding the foregoing, for purposes of Section 8.01(d)(x), it shall not
constitute a material violation or breach of this Section 6.06 if the Company
is not able to cure any defects or other items reflected on any title
commitment for properties identified in Appendix E hereto to which the
Purchaser objects after receipt thereof, and, as a result, the Company does not
deliver to the Purchaser at Closing Title Policies with respect to such
properties that are subject to no defects other than to Permitted Encumbrances.

             SECTION 6.07.    Notification of Certain Other Matters.  The
Company shall promptly notify the Purchaser of:

             (a)     any actions, suits, inquiries, investigations or
proceedings commenced or threatened against or affecting the Company which, if
pending on the date hereof, would have been required to have been set forth or
described in any Schedule required hereby or which relate to the transactions
contemplated by this Agreement;

             (b)     any notice or other communication from any Person alleging
that the Consent of such Person is or may be required in connection with the
transactions contemplated by this Agreement;

Authority in connection with the transactions contemplated by this Agreement;
and

             (d)     any fact, development or occurrence that constitutes a
Material Adverse Change or, so far as reasonably can be foreseen at the time of
its occurrence, could have a Material Adverse Effect.

             SECTION 6.08.    Supplemental Disclosure.  The Vista Parties shall
have the continuing obligation promptly to supplement or amend the Schedules
required hereby or any writing previously delivered to the Purchaser with
respect to any matter hereafter arising or discovered which, if existing or
known at the date hereof, would have been required to be set forth or described
in a Schedule required hereby or in any writing delivered to the Purchaser;
provided, however, that for the purpose of the rights and obligations of the
parties hereunder, any such supplemental or amended disclosure shall not be
deemed to have been disclosed as of the date hereof unless so agreed to in
writing by the Purchaser.

  SECTION 6.09.    Delivery of Filing Date Certificates, Opinions and Notices.

             (a)     At least one full Business Day prior to the date of
commencement of the Bankruptcy Case (the "Filing Date"), the Vista Parties

             Vista Parties contained in this Agreement is true and correct as
             of such date as if made on such date (except for representations
             and warranties made as of a specific date, which shall be true and
             correct as of such date) and (ii) the Vista Parties have performed
             and complied with all provisions, covenants and conditions
             contained in this Agreement which are required to be performed or

or imposed on any of them at any time after such date, together with a brief
statement as to the basis for such estimate.  It is expressly understood and
agreed that such Purchaser Claims Notice shall be for informational purposes
only, and (except as set forth in the definition of the term "Termination
Threshold" contained in Section 1.01 hereof) neither the information contained
in such notice nor the failure of such notice to disclose any fact known to the
Purchaser shall qualify, limit or otherwise modify the rights, duties and
obligations of the parties as set forth in this Agreement or the nature and
scope of the representations and warranties made by the Vista Parties herein.

             SECTION 6.10.    Indemnification and Other Arrangements; Releases.

             (b)     Effective as of the Closing Date, the Purchaser hereby

existing or hereafter arising, in law, equity or otherwise which the Purchaser
may have against any of the Released Parties based in whole or in part on any
act or omission, transaction, event or other occurrence occurring prior to or
on the Closing Date; provided, however, that the foregoing release shall not
apply to claims, obligations, suits, judgments, damages, rights, causes of
action or liabilities arising from or based upon any act, omission,
transaction, event or other occurrence which constitutes actual fraud or
criminal behavior on the part of any Released Party.

             (c)     The provisions of this Section 6.10 shall inure to the
benefit of the directors and officers of the Company and the other persons

Parties of their representations and warranties have resulted or could
reasonably be expected to result in Purchaser Claims in an aggregate amount
exceeding $10,000,000 (it being understood and agreed that (A) for purposes of

             between the Company and Society Shareholder Services, Inc., as
             escrow agent (as successor to Ameritrust Company, National

             reasonable discretion, that the condition set forth in Section

             period of time; provided, however, that the Purchaser shall only
             be entitled to terminate this Agreement pursuant to this Section

             September 30, 1995 for any reason (provided, however, that if an
             arbitration proceeding shall have been commenced pursuant to
             Sections 2.02(b), 7.01(a)(i) or 8.01(d)(xi) and be pending and not
             stayed on September 30, 1995, such date shall be extended to such
             later date as such proceeding is finally concluded);

                     (vi)     ten calendar days shall have elapsed after the
             delivery by the Company of an Overbid Notice to the Purchaser,
             unless the Company shall have notified the Purchaser in writing

             participate in any further discussions or negotiations with any
             Third Party with respect to the Acquisition Proposal that was the
             subject of such notice;

             been waived by the Purchaser;

                     (ix)     there shall have been any violation or breach on
             the part of the Vista Parties of any covenant or agreement
             contained in Article V hereof or Section 6.03, 6.04 or 6.05 hereof
             which shall not have been cured within five days after receipt of
             notice of such violation or breach from the Purchaser;

                     (x)      there shall have been any material violation or

             (other than the covenants and agreements referred to in clause
             (viii) and (ix) above) contained in this Agreement which shall not
             have been cured within 30 days after receipt of notice of such
             violation or breach from the Purchaser;

                     (xi)     there shall have been any violation or breach by
             any of the Vista Parties of any representation or warranty
             contained in this Agreement, which in the reasonable judgment of
             the Purchaser, has resulted or is reasonably expected to result in
             any Purchaser Claims in an aggregate amount exceeding the
             Termination Threshold (it being understood and agreed that (A) for
             purposes of this clause (xi) all such representations and
             warranties shall be construed as if they were not qualified in any
             manner as to materiality and (B) any dispute between the parties
             as to whether the Purchaser is entitled to terminate this
             Agreement after the Filing Date pursuant to this

             with the provisions of Appendix A hereto); or

                     (xii)    there shall have occurred any event, fact or
             development which, in the reasonable judgment of the Purchaser,
             has rendered the fulfillment of any condition to the obligations
             of the Purchaser set forth in Section 7.01 hereof impossible;

provided, however, that, in the case of any termination pursuant to clause (ix)
or (x) above, the Purchaser has diligently and in good faith performed or
complied in all material respects with the agreements and covenants required to
be performed by it hereunder; and

             (e)     by the Vista Parties jointly if:

                     (i)      all of the Overbid Termination Conditions shall 
             have been satisfied;

                     (ii)     there shall have been any material violation or
             breach by the Purchaser of any covenant or agreement contained in
             this Agreement which shall not have been cured within 30 days
             after receipt of notice of such violation or breach from the Vista
             Parties;

                     (iii)    there shall have been any violation or breach by
             the Purchaser of any representation or warranty contained in this
             Agreement which, in the reasonable judgment of the Vista Parties,
             has resulted or is reasonably expected to result in any Vista
             Party claims or liabilities in aggregate amount exceeding the
             Termination Threshold (it being understood and agreed that for
             purposes of this clause (iii) all such representations and
             warranties shall be construed as if they were not qualified in any
             manner as to materiality); or

                     (iv)     there shall have occurred any event, fact or
             development which, in the reasonable judgment of the Vista
             Parties, has rendered the fulfillment of any condition to the
             obligations of the Vista Parties set forth in Section 7.02 hereof
             impossible;

provided, however, that, in the case of any termination pursuant to clause (ii)
above, the Vista Parties have diligently and in good faith performed or
complied in all material respects with the agreements and covenants required to
be performed by them hereunder.

             SECTION 8.02.    Effect of Termination.  In the event of the
termination of this Agreement in accordance with Section 8.01 hereof, this
Agreement shall forthwith become void and of no further force or effect, and
there shall be no liability hereunder on the part of any party or its
Affiliates, directors, officers, shareholders, agents or other representatives;
provided, however, that (i) this Section 8.02 and Sections 8.03, 9.01 and 9.03
hereof shall survive any termination of this Agreement and (ii) nothing
contained herein shall relieve any party from liability for any breach of this
Agreement.

             SECTION 8.03.    Termination Payments.

             (a)     If this Agreement is terminated (whether automatically or
by the Purchaser or the Vista Parties) for any reason prior to the time the
Company shall have delivered the Termination Fee (as hereinafter defined) to
the Termination Fee Escrow Agent (other than by the Vista Parties pursuant to
Section 8.01(e)(ii) or (iii) hereof), the Company shall pay to the Purchaser a
fee of one million eight hundred thousand dollars ($1,800,000) (the
"Termination Fee"), which fee shall be paid no later than one Business Day
after the date of termination of this Agreement by wire transfer of immediately
available funds to such account as the Purchaser shall designate in a written
notice delivered to the Company.

             (b)     Subject only to the entry of the Interim Order authorizing
the performance of this Section 8.03(b), immediately after such order has been
entered, (i) the Company shall deliver the Termination Fee to the Termination
Fee Escrow Agent and (ii) the Vista Parties, the Purchaser and the Termination
Fee Escrow Agent shall





                                     -42-

enter into the Termination Fee Escrow Agreement.  If this Agreement is
terminated (whether automatically or by the Purchaser or the Vista Parties) for
any reason after the time the Company shall have delivered the Termination Fee
to the Termination Fee Escrow Agent, the parties shall take all action
necessary in order to cause the Termination Fee Escrow Agent promptly to
deliver the Termination Fee Deposit as follows:

                     (i)      to the Purchaser, if this Agreement is terminated
             (whether automatically or by the Purchaser or the Vista Parties)
             for any reason other than as specified in clause (ii) below; or

                     (ii)     to the Company, if this Agreement is terminated
             by the Vista Parties pursuant to Section 8.01(e)(ii) or (iii)
             hereof.

             (c)     If this Agreement is terminated for any reason, the
parties shall take all action necessary in order to cause the Earnest Money
Escrow Agent promptly to deliver the Earnest Money Deposit as follows:

                     (i)      to the Purchaser, if this Agreement is terminated
             (whether automatically or by the Purchaser or the Vista Parties)
             for any reason other than as specified in clause (ii) below; or

                     (ii)     to the Company, if this Agreement is terminated
             by the Vista Parties pursuant to Section 8.01(e)(ii) or (iii)
             hereof.

             (d)     If the Purchaser is required for any reason to seek
judicial enforcement of any of the obligations of the Vista Parties under this
Section 8.03, the Vista Parties shall jointly and severally pay, or reimburse
the Purchaser for, all costs and expenses (including fees and disbursements of
counsel) that are incurred by the Purchaser in enforcing the provisions of this
Section 8.03.

             (e)     Any amounts paid pursuant to this Section 8.03 shall be
paid without set-off or deduction.

             Attention: J. Ronald Trost

All notices and other communications hereunder that are addressed as provided
in or pursuant to this Section 9.02 shall be deemed duly and validly given (a)

delivered by cable, telex or facsimile transmission, upon transmission thereof
and receipt of the appropriate answerback.

             SECTION 9.03.    Public Announcements.  The Vista Parties and the
Purchaser will consult with each other before issuing any press release or
otherwise making any public statements with respect to this Agreement, the
Bankruptcy Case, the Reorganization Plan or the other transactions contemplated
by this Agreement, and shall not issue any such press release or make any such
public statement prior to such consultation, except as may be required by law
or by obligations pursuant to any listing agreement with any national
securities exchange or automated quotation system upon which the securities of
such issuer are traded.

             SECTION 9.04.    Amendment; Waivers.  The terms and provisions of
this Agreement may be modified or amended only by a written instrument executed
by each of the parties hereto, and compliance with any term or provision hereof
may be waived only by a written instrument executed by each party entitled to
the benefits





                                     -44-

<PAGE>   50
of the same.  Except as expressly provided herein to the contrary, no failure
to exercise any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right, power or privilege
granted hereunder.

             SECTION 9.05.    Entire Agreement.  This Agreement (including the
Appendices, Exhibits and Schedules hereto and the certificates, opinions and
documents delivered in accordance with the provisions hereof) constitutes the
entire agreement among the parties with respect to the subject matter hereof
and supersedes all prior written or oral agreements and understandings and all
contemporaneous oral agreements and understandings among the parties or any of
them with respect to the subject matter hereof.  All Appendices, Exhibits and
Schedules hereto and certificates, opinions and other documents delivered in
accordance with the provisions hereof are expressly made a part of this
Agreement.

             SECTION 9.06.    Parties in Interest; Assignment.  This Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns (it being understood and agreed that nothing
contained in this Agreement is intended to confer any rights, benefits or
remedies of any kind or character on the holders of Existing Securities or,
except as expressly provided herein, any other Person under or by reason of
this Agreement).  No party may assign this Agreement without the prior written
consent of each of the other parties hereto; provided, however, that after the
Closing Date, the Purchaser may assign this Agreement to any of its Affiliates
without the consent of any other party, but such assignment shall not relieve
the Purchaser of any of its obligations hereunder to the extent that such
obligations are not performed by the assignee.  It is expressly understood and
agreed that any attempted or purported assignment by any party of this
Agreement in violation of this Section 9.06 shall be null and void.

             SECTION 9.07.    Governing Law.  This Agreement shall be governed
by and construed and interpreted in accordance with the laws of the State of
Texas, without regard to the principles of conflicts of law that would result
in the application of the laws of any other jurisdiction.

             SECTION 9.08.    Severability.  In the event any provision
contained herein shall be held to be invalid, illegal or unenforceable for any
reason, the invalidity, illegality or unenforceability thereof shall not affect
any other provision hereof.

             SECTION 9.09.    Specific Performance.  The parties hereto agree
that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with the terms hereof.
Accordingly, the parties agree that each of them shall be entitled to seek
injunctive relief to prevent breaches of the terms of this Agreement and to
seek specific performance of the terms hereof, in addition to any other remedy
now or hereafter available at law or in equity, or otherwise.  Without limiting
the generality of the foregoing, it is expressly understood and agreed that, in
the event of a breach by the Vista Parties of their obligations under Section
6.02(a) hereof not to enter into an agreement with a Third Party with respect
to an Overbid Transaction unless the condition set forth in clause (y) of such
provision shall have been fulfilled, the Purchaser shall be entitled to
specific performance of such obligations without the necessity of demonstrating
irreparable damage or of complying with any requirement as to the posting of a
bond or other security (it being understood that any such requirement is hereby
expressly waived by the Vista Parties).

             SECTION 9.10.    Interpretation.

             (a)     The headings herein are for convenience of reference only,
do not constitute a part of this Agreement and shall not be deemed to limit,
extend or otherwise affect the meaning of any of the provisions hereof.

             (b)     In interpreting the provisions of this Agreement, time is
of the essence in the performance of the obligations of the parties.

             (c)     The obligations of the Vista Parties set forth in this
Agreement shall in no event be limited by or subject to their obligations under
any other agreement or document to which any of them is a party or is bound as
of the date hereof.

             (d)     As used herein, the phrase "to the knowledge of the Vista
Parties" or any phrases of like import shall be deemed to refer to the
knowledge of the officers of the Vista Parties (other than the two Assistant
Secretaries of the Company, which the Vista Parties represent do not perform
any executive functions) and employees of the Vista Parties with the title
"Project Manager" or "Assistant Project Manager" and other employees performing
similar functions.  Furthermore, in interpreting any such phrase, the Vista
Parties shall be deemed to have knowledge of any fact, event or development
that comes to the attention of any such persons in the course of performance of
his or her obligations as an officer or employee of one or more of the Vista
Parties; provided, however, that such persons shall not be required to conduct
any special or additional investigation for purposes of discovering any such
fact, event or development.

             SECTION 9.11.    Counterparts.  This Agreement may be executed in
one or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.


             IN WITNESS WHEREOF, the parties have caused this Agreement to be
duly executed as of the date first above written.

                                  ARBITRATION

                                       OF

                                CERTAIN DISPUTES


             Any dispute, disagreement or controversy between the Purchaser and
the Vista Parties arising prior to or on the Closing Date as to (i) the amount
of any Purchaser Claims incurred by or imposed on the Purchaser or any of the
Vista Parties or more likely than not to be incurred by or imposed on any of
them which is set forth in a Purchaser Claims Notice delivered pursuant to
Section 2.02(b) of the Second Amended and Restated Securities Purchase
Agreement, dated as of December 18, 1994 (the "Agreement"), among the Vista
Parties and the Purchaser, (ii) whether the condition to the obligations of the
Purchaser set forth in Section 7.01(a)(i) of the Agreement has been fulfilled
or (iii) whether the Purchaser is entitled to terminate the Agreement after the
Filing Date pursuant to Section 8.01(d)(xi) of the Agreement (any dispute,
disagreement or controversy as to the matters referred to in clause (i), (ii)
or (iii) above being hereinafter referred to as a "Covered Dispute") shall be
exclusively and finally settled by arbitration in accordance with the
provisions of this Appendix.   Capitalized terms used herein without definition
shall have the respective meanings set forth in the Agreement.

             1.      The Vista Parties may dispute any determination by the
Purchaser as to the matters referred to in clause (i), (ii) or (iii) above if,
and only if, within five Business Days after receipt of written notification
from the Purchaser of such determination,  the Vista Parties (a) deliver to the
Purchaser a written notice (a "Special Arbitration Notice") of their intention
to arbitrate, which notice shall contain a reasonably detailed statement of the
nature of the Covered Dispute, and (b) take such other steps as are necessary
to commence arbitration proceedings under the Commercial Arbitration Rules of
the American Arbitration Association (including, but not limited to, the
payment of any administrative fee provided for under such rules).

             2.      As promptly as practicable after delivery of a Special
Arbitration Notice, three arbitrators who are experienced in the resolution of
disputes arising in connection with the purchase or sale of businesses or
interests therein shall be chosen in accordance with the Commercial Arbitration
Rules of the American Arbitration Association; provided, however, that the
parties shall use their reasonable best efforts to ensure that such arbitrators
are chosen no later than ten Business Days after the delivery of such notice.

             3.      The arbitration shall be heard by a panel of the three
arbitrators so chosen (the "Special Arbitration Panel"), and the resolution of
the dispute shall be determined by a majority vote of the Special Arbitration
Panel.  The Commercial Arbitration Rules of the American Arbitration
Association shall govern the conduct of the arbitration; provided, however,
that the Special Arbitration Panel (i) shall require that all testimony taken
in connection with the arbitration be transcribed, (ii) shall use its best
efforts to ensure that the arbitration proceedings are concluded expeditiously
(but in no event later than 20 Business Days after the selection of the Special
Arbitration Panel) and (iii) shall render its judgment within two Business Days
after the conclusion of the arbitration proceedings.

             4.      At least five Business Days prior to the commencement of
the arbitration proceedings, each of the Purchaser and the Vista Parties shall
submit in writing to the other party or parties (i) a list (and, if requested
by the other party or parties, copies) of all documents expected to be
presented to the Arbitration Panel or otherwise used or relied upon by it in
the arbitration proceedings and (ii) a list of all experts and other witnesses
whose testimony is expected to be taken by it in such proceedings.

             5.      Any award rendered by the Special Arbitration Panel shall
be final, conclusive and binding upon the parties, and judgment thereon may be
entered and enforced in any court of competent jurisdiction.

             6.      The Purchaser on the one hand and the Vista Parties on the
other shall be assessed equally all fees, costs and expenses of the
arbitration.  The Purchaser and the Vista Parties shall each bear their own
legal expenses, attorneys' fees and costs of experts and witnesses; provided,
however, that if a Covered Dispute is resolved in favor of one party in all
material respects, then the Special Arbitration Panel may apportion the fees,
costs and expenses incurred by the prevailing party (including legal expenses,
attorneys' fees and costs of experts and witnesses) in such manner as the
Special Arbitration Panel deems equitable.

    of the Excess Purchaser Claims Amount.  As used herein, the term "Regular
    Equity Fraction" means a fraction the numerator of which is the total
    number of issued and outstanding shares of Existing Common Stock held by
    holders of Existing Common Stock other than the Agreeing Holders on the
    Record Date and the denominator of which is the total number of issued and
    outstanding shares of Existing Common Stock on the Record Date.

                     consideration:

                     b.       cash in an amount equal to one-half of the excess
             of (A) the result obtained by multiplying (i) the Agreeing Holders
             Fraction by (ii) the excess of (1) $8,920,0002 over (2) 58.99% of
             the Excess Purchaser Claims Amount.

C.  Allocation to Management

             The Management Restructuring Payments made to the Managers,
officers and employees of the Company and Subsidiaries will be in the amount of
$1,550,000, reduced by 1.69% of the Excess Purchaser Claims Amount.

Property of the Company or any Subsidiary made pursuant to any Property
Agreement effective from and after December 18, 1994 shall be made in
accordance with the following procedure:

             1.      A Sales Transaction Evaluation ("STE") in the form
attached as Exhibit A hereto for such proposed disposition of Real Property
will be developed in accordance with the current practices of the Company and
its Subsidiaries as disclosed to the Purchaser.

             2.      The Company or any Subsidiary shall submit the STE with

President of the Purchaser in which to (a) approve the STE by initialing and

respond to the STE within three Business Days after receipt from the Company or
any Subsidiary of either the STE or the Company's response to a request for
clarification made by the Purchaser in connection with the STE, the Purchaser
shall be deemed to have approved the STE.

         such dividends to the dividends payable on any other class or classes
         of capital stock of the Corporation or on any series of Preferred
         Stock of the Corporation, and whether such dividends shall be
         cumulative;

         of such sinking fund or redemption or purchase account;

                 6.       the rights of the holders of shares of the series
         upon voluntary or involuntary liquidation, merger, consolidation,
         distribution or sale of assets, dissolution or winding up of the

                 7.       whether shares of the series shall have voting rights
         in addition to the voting rights provided by law, which may include
         (a) the right to more or less than one vote per share on any or all
         matters submitted to a vote of the stockholders of the Corporation and
         (b) the right to vote, as a series by itself or together with any
         other series of Preferred Stock or together with all series of
         Preferred Stock as a class or with the Common Stock as a class, upon

         Preferred Stock or together with all series of Preferred Stock as a
         class, to elect one or more directors of the Corporation in the event
         there shall have been a default in the payment of dividends on any

         such other conditions as the Board of Directors may determine);

                 8.       whether shares of the series shall be subject to
         restrictions on transferability, which may include a prohibition
         against the transfer of any such shares or any interest therein except
         in tandem with the shares of another class or series of capital stock,
         including shares of Common Stock; and

                 9.       any other powers, preferences and relative,
         participating, optional or other rights, and the qualifications,
         limitations or restrictions thereof.

Subject to the express terms of any series of Preferred Stock outstanding at
any time, the vote or consent of the holders of Preferred Stock of any series
shall not be required for the issuance of any other series of Preferred Stock,
regardless of whether the powers, preferences and rights of such other series
shall be fixed by the Board of Directors as senior to, on a parity with or
junior to the powers, preferences and rights of such outstanding series.

                 B.       Common Stock.

                 1.       Dividends.  Subject to the rights, if any, of the
         holders of Preferred Stock with respect to the payment of dividends
         and the requirements, if any, with respect to the setting aside of
         sums as sinking funds or redemption or purchase accounts for the
         benefit of such holders and subject to any other conditions that may
         be fixed in accordance with the provisions of paragraph A of this
         Article FOURTH, then, but not otherwise, the holders of Common Stock
         shall be entitled to receive such dividends, if any, as may be





                                      -3-
<PAGE>   4
         declared from time to time by the Board of Directors on the Common
         Stock out of assets which are legally available therefor.  Any such
         dividends shall be distributed among the holders of the Common Stock
         pro rata in accordance with the number of shares of such stock held by
         each such holder.

                 2.       Liquidation.  In the event of any voluntary or
         involuntary liquidation, distribution or sale of assets, dissolution
         or winding-up of the Corporation, after payment or provision for
         payment of the debts and liabilities of the Corporation and after
         distribution to the holders of Preferred Stock of the amounts fixed in
         accordance with the provisions of paragraph A of this Article FOURTH,
         the holders of the Common Stock shall be entitled to receive all the
         remaining assets of the Corporation, tangible and intangible, of
         whatever kind available for distribution to stockholders.   Any such
         distribution shall be made among the holders of Common Stock pro rata
         in accordance with the number of shares of such stock held by each
         such holder.

                 3.       Voting.  Except as may otherwise be required by law
         or the provisions of any resolution or resolutions adopted by the
         Board of Directors pursuant to paragraph A of this Article FOURTH,
         each holder of Common Stock shall have one vote for each share of
         Common Stock held by such holder on each matter submitted to a vote of
         the stockholders.  Except as otherwise provided under applicable law,
         holders of the Class A Common Stock and holders of the Class B Common
         Stock shall vote together as a single class in the election of
         directors and each other matter submitted to a vote of the
         stockholders of the Corporation.  Cumulative voting of shares of
         Common Stock shall not be permitted.

                 4.       Restrictions on Transfer of Class A Common Stock.

                 (a)      Prohibited Transfers.  For a period of 18 months from
         and after the date upon which shares of Class A Common Stock are first
         issued pursuant to the Reorganization Plan, no holder of shares of
         Class A Common Stock shall Transfer any such shares or any interest
         therein to any Person; provided, however, that the provisions of this
         paragraph (a) shall not be construed to prohibit a Transfer of shares
         of Class A Common Stock to a Person to whom shares of Class A Common
         Stock were issued pursuant to the Second Amended and Restated
         Securities Purchase Agreement, dated as of December 18, 1994, among
         the Corporation, Vista Mortgage & Realty, Inc., Braewood Development
         Corp., Panoramic Land, Inc. and Centex International, Inc., as amended
         by Amendment No. 1 to Second Amended and Restated Securities Purchase
         Agreement, dated as of July 14, 1995, and Amendment No. 2 to Second
         Amended and Restated Securities Purchase Agreement, dated as of
         September 15, 1995, or the Reorganization Plan.

                 (b)      Transfers of Tandem Shares.  A share of Class A
         Common Stock constitutes a part of a unit (each, a "Unit") consisting
         of one share of Class A Common Stock and one share of Series A
         Preferred Stock.  Shares of Class A Common Stock and Series A





                                      -4-
<PAGE>   5
         Preferred Stock included in the same Unit ("Tandem Shares") shall be
         evidenced by separate certificates issued by the Corporation, each of
         which shall bear a serial designation identifying the Unit or Units of
         which such shares are a part.  No holder of shares of Class A Common
         Stock shall Transfer any such shares or any interest therein to any
         Person unless all Tandem Shares included in the Unit or Units of which
         such shares are a part are Transferred to such Person in a single
         transaction or a series of contemporaneous transactions.

                 (c)      Effect of Purported Transfers.  Any attempted or
         purported Transfer of shares of Class A Common Stock in violation of
         subparagraphs (a) or (b) above shall not be effective to Transfer
         ownership of such shares to the purported Transferee thereof, who
         shall not be entitled to any rights as a stockholder of the
         Corporation with respect to the shares purported to be Transferred
         (including, but not limited to, the right to vote such shares or to

         that there has been or is threatened an attempted or purported
         Transfer of shares in violation of the aforementioned provisions, the
         Board of Directors may take such action as it deems advisable to give
         effect to the provisions of this paragraph B.4. of Article FOURTH,
         including, but not limited to, refusing to give effect on the books of
         the Corporation to such attempted or purported Transfer or instituting
         legal proceedings to enjoin or rescind the same.

                 (d)      Legend.  All certificates evidencing shares of Class
         A Common Stock shall bear a conspicuous legend referencing the
         restrictions set forth in this paragraph B.4. of Article FOURTH.

                 (e)      Certain Definitions.     As used in this paragraph
         B.4. of Article FOURTH, the terms set forth below shall have the
         following respective meanings:

                          "Person" means any individual, corporation, estate,
         trust, association, company, partnership, joint venture or other

                          "Series A Preferred Stock" has the meaning set forth

         Stock by Resolution of the Board of Directors Providing For Issues of
         Preferred Stock Designated "Series A Preferred Stock" and "Series B
         Preferred Stock," to be filed by the Corporation with the Secretary of
         State of the State of Nevada on the 26th day of September, 1995.

         means of conveying legal or beneficial ownership of such shares,
         whether direct or indirect and whether voluntary or involuntary,

such acts and things as may be exercised or done by the Corporation, subject to
the provisions of the NRS, these Amended and Restated Articles of Incorporation

shall constitute the entire Board of Directors of the Corporation shall be as
from time to time fixed by, or in the manner provided in, the Bylaws of the
Corporation; provided, however, that (i) the number of directors shall in no
event be less than three nor more than fifteen and (ii) no decrease in the

incumbent director.

be by written ballot unless the Bylaws of the Corporation so provide.

         to be made a party to, or is involved in any threatened, pending or
         completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative, by reason of the fact that such
         person is or was a director or officer of the Corporation or is or was
         serving at the request of the Corporation as a director or officer of
         another corporation, partnership, joint venture, trust or other
         enterprise, shall be indemnified and held harmless by the Corporation
         to the fullest extent permitted by Nevada law.  The right to

         right to be paid by the Corporation the expenses incurred in
         connection with any such proceeding in advance of its final
         disposition to the fullest extent authorized by Nevada law.  The right
         to indemnification conferred in this Article SIXTH shall be a contract
         right.

                 2.       The Corporation may, by action of its Board of
         Directors, provide indemnification to such of the employees and agents
         of the Corporation to such extent and to such effect as the Board of
         Directors shall determine to be appropriate and authorized by Nevada
         law.

                 C.       Insurance.  The Corporation shall have the power to
purchase and maintain insurance on behalf of any person who is or was a

at the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any expenses, liability or loss incurred by such person in any such
capacity or arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability under Nevada law.

                 D.       Non-Exclusivity.  The rights and authority conferred
in this Article SIXTH shall not be exclusive of any other right which any
person may otherwise have or hereafter acquire.

by the Corporation as treasury stock and subsequently reissued or sold or
otherwise disposed of, or any notes, debentures, bonds or other securities
convertible into, or any warrants, rights or options exercisable for, any
shares of any class or series of capital stock of the Corporation, whether or
not the issuance of any such shares or such notes, debentures, bonds or other
securities or warrants, rights or options would adversely affect the dividend,
voting or any other rights of such stockholder.

be issued; provided that this provision, included in these Amended and Restated
Articles of Incorporation in compliance with Section 1123 of the United States
Bankruptcy Code, 11 U.S.C. Section  1123, shall have no force and effect except
to the extent required by such Section so long as such Section is in effect and
applicable to the Corporation.

                 NINTH:  The Corporation reserves the right to amend, alter,
change, rescind or repeal any provision contained in these Amended and Restated
Articles of Incorporation, in the manner now or hereafter prescribed by

                 2.       Voting Rights.   In addition to any voting rights
granted to the holders of Series A Preferred Stock pursuant to Sections 7 and 8
below or under applicable law, the holders of Series A Preferred Stock shall be
entitled to vote, together with the holders of Common Stock as a single class,
on the election of directors of the Corporation and each other matter submitted
to a vote of the stockholders of the Corporation.   Each holder of Series A
Preferred Stock shall be entitled to one vote for each share of this series
held by such holder.   Cumulative voting of shares of Series A Preferred Stock
is prohibited.

                 3.       Dividends.

                 (a)      The holders of shares of Series A Preferred Stock
         shall be entitled to receive, as and when declared by the Board of
         Directors out of funds legally available therefor, cumulative cash
         dividends at the Applicable Dividend Rate for each Dividend Rate
         Period.  Accrued but unpaid dividends on Series A Preferred Stock
         shall not bear interest.

                 (b)      Dividends on shares of Series A Preferred Stock shall
         accrue from the Date of Original Issue of Series A Preferred Stock and

         payable to the holders of shares of Series A Preferred Stock as their
         names shall appear on the stock transfer books of the Corporation on
         the fifth Business Day next preceding the applicable Quarterly
         Dividend Payment Date.  Dividends in arrears for any past quarterly
         dividend period or periods may be declared and paid to the holders of
         shares of Series A Preferred Stock at any time, without reference to
         any regular Quarterly Dividend Payment Date, as may be fixed by the
         Board of Directors.

                 (d)      Each share of Series A Preferred Stock shall rank
         prior to each share of Series B Preferred Stock or Junior Stock with
         respect to the payment of dividends.  If in respect of any past
         quarterly dividend period or periods full dividends upon the
         outstanding shares of Series A Preferred Stock shall not have been
         paid, the amount of the deficiency shall be fully paid or declared and
         set apart for payment before any dividend shall be paid or set apart
         for payment upon any shares of Series B Preferred Stock or Junior
         Stock.

                 4.       Dividend Rate Reset and Tender Procedures.

                 (a)      No later than 30 days prior to the next Dividend Rate
         Reset Date, the Board of Directors of the Corporation shall (i) select
         the Eligible Firm that will determine the Applicable Dividend Rate for
         the next Dividend Rate Period (the "Pricing Agent") and (ii) enter
         into an agreement with the Pricing Agent pursuant to which such agent
         will agree to perform the functions and comply with the procedures
         specified in this Section 4.

<PAGE>   3
                 (b)      The Pricing Agent shall determine in its sole
         judgment the lowest dividend rate per annum (expressed as a percentage
         of the Series A Liquidation Preference) that it believes would enable
         it to sell on behalf of the holders thereof all outstanding Units at a
         price per Unit equal to the Base Price (such rate being hereinafter
         referred to as the "Proposed Dividend Rate").  On any Reset Notice
         Date, the Pricing Agent shall notify the holders of Units of the
         Proposed Dividend Rate and shall provide them with appropriate
         instructions (the "Reset and Tender Instructions") for use in
         complying with the procedures set forth in this paragraph (b) (the
         "Reset and Tender Procedures").  Prior to or on the Reset Election
         Date, each holder of Units shall notify the Pricing Agent whether it
         elects (i) to continue to hold all of the Units beneficially owned by
         it or (ii) to tender all of such Units to the Pricing Agent for sale
         to one or more Purchasers at a price per Unit equal to the Base Price.
         Any such notice shall constitute an irrevocable election on the part
         of a holder, and the irrevocability of such election may not be waived
         by the Pricing Agent without the prior written consent of the
         Corporation.  As promptly as practicable after the Reset Election
         Date, the Pricing Agent will attempt to arrange for the sale of any
         and all Units tendered to it pursuant to this paragraph (b) to one or
         more Purchasers at a price per Unit equal to the Base Price.  On the
         Tender Acceptance Date , the Pricing Agent shall notify all holders
         that tendered Units pursuant to this paragraph (b) whether such Units
         will be accepted for purchase.  The sale of any Units accepted for
         purchase pursuant to this paragraph (b) shall be effectuated as
         promptly as practicable after the Tender Acceptance Date in accordance
         with the Reset and Tender Instructions.  If either (i) no Units are
         tendered to the Pricing Agent pursuant to this paragraph (b) or (ii)
         all Units that are tendered to the Pricing Agent pursuant to this
         paragraph (b) are accepted for purchase, shares of Series A Preferred
         Stock shall accrue dividends for the next Dividend Rate Period at the
         Proposed Dividend Rate.

                 (c)      If the Applicable Dividend Rate at which shares of
         Series A Preferred Stock shall accrue dividends for the next Dividend
         Rate Period is not determined in accordance  with paragraph (b) above,
         the Pricing Agent and the holders of shares of Series A Preferred
         Stock shall repeat the Reset and Tender Procedures until such time as
         (i) the Applicable Dividend Rate has been determined or (ii) the Reset
         and Tender Procedures shall have been complied with on a total of
         three separate occasions; provided, however, that, on each occasion in
         which the Reset and Tender Procedures are repeated pursuant to this
         paragraph (c), the Pricing Agent may fix or alter the applicable Reset
         Notice Date, Reset Election Date and Tender Acceptance Date by
         specifying such dates in the Reset and Tender Instructions provided to
         the holders of Units.

                 (d)      If the Applicable Dividend Rate at which shares of
         Series A Preferred Stock shall accrue dividends is not determined in
         accordance with paragraph (b) or (c) above, shares of Series A
         Preferred Stock shall accrue dividends for the next Dividend Rate
         Period at a rate of 20% per annum.

<PAGE>   4
                 (e)      The Pricing Agent shall be entitled to purchase for
         its own account any Units tendered to it pursuant to the Reset and
         Tender Procedures which are not sold to other Purchasers.
         Notwithstanding anything to the contrary contained in this Section 4,
         in no event shall the Pricing Agent (i) be obligated to purchase any
         Units tendered to it pursuant to the Reset and Tender Procedures or
         (ii) have any other liability to the holders of Units tendered to it
         pursuant to such procedures in the event that it is unable to arrange
         for the purchase of such Units by one or more Purchasers.

                 5.       Liquidation.  Each share of Series A Preferred Stock
shall rank prior to each share of Series B Preferred Stock and Junior Stock
with respect to the distribution of assets upon a Liquidation .  In the event
of any Liquidation, each holder of a share of Series A Preferred Stock shall be
entitled to receive, before any distribution shall be made to the holders of
Series B Preferred Stock or Junior Stock, an amount per share equal to $1,000
(the "Series A Liquidation Preference"), plus an amount equal to all accrued
and unpaid dividends thereon, whether or not declared, to the date of payment
thereof.  In the event that there are not sufficient assets available to permit
payment in full of the Series A Liquidation Preference to all holders of
outstanding shares of Series A Preferred Stock, then the remaining assets of
the Corporation shall be distributed to the holders of this series in
proportion to the Series A Liquidation Preferences of the shares of Series A
Preferred Stock held by them.  After payment shall have been made in full to
the holders of the Series A Preferred Stock, the remaining assets and funds of
the Corporation shall be distributed among the holders of Series B Preferred
Stock and Junior Stock according to their respective rights.

                 6.       Transfer.

                 (a)      Prohibited Transfers.   For a period of 18 months
         from and after the Date of Original Issuance of Series A Preferred
         Stock, no holder of shares of Series A Preferred Stock shall Transfer
         any such shares or any interest therein to any Person; provided,
         however, that the provisions of this paragraph (a) shall not be
         construed to prohibit a Transfer of shares of Series A Preferred Stock
         to a Person to whom shares of Series A Preferred Stock were issued
         pursuant to the Securities Purchase Agreement or the Reorganization
         Plan.

                 (b)      Transfers of Tandem Shares.  A share of Series A
         Preferred Stock constitutes a part of a unit (each, a "Unit")
         consisting of one share of Class A Common Stock and one share of
         Series A Preferred Stock.  Shares of Class A Common Stock and Series A
         Preferred Stock included in the same Unit ("Tandem Shares") shall be
         evidenced by separate certificates issued by the Corporation, each of
         which shall bear a serial designation identifying the Unit or Units of
         which such shares are a part.  No holder of shares of Series A
         Preferred Stock shall Transfer any such shares or any interest therein
         to any Person unless all Tandem Shares included in the Unit or Units
         of which such shares are a part are Transferred to such Person in a
         single transaction or a series of contemporaneous transactions.

                 (c)      Effect of Purported Transfers.  Any attempted or
         purported Transfer of shares of Series A Preferred Stock in violation
         of paragraph (a) or (b) above shall not be effective to Transfer
         ownership of such shares to the purported Transferee thereof, who
         shall not be entitled to any rights as a stockholder of the
         Corporation with respect to the shares purported to be Transferred
         (including, but not limited to, the right to vote such shares or to
         receive dividends with respect thereto).  All rights with respect to
         any shares attempted or purported to be Transferred in violation of
         the aforementioned provisions shall remain the property of the Person
         who initially attempted or purported to transfer such shares in
         violation thereof.  Upon a determination by the Board of Directors
         that there has been or is threatened an attempted or purported
         Transfer of shares in violation of the aforementioned provisions, the
         Board of Directors may take such action as it deems advisable to give
         effect to the provisions of this Section 6, including, but not limited
         to, refusing to give effect on the books of the Corporation to such
         attempted or purported Transfer or instituting legal proceedings to
         enjoin or rescind the same.

                 (d)      Legend.  All certificates evidencing shares of Series
         A Preferred Stock shall bear a conspicuous legend referencing the
         restrictions set forth in this Section 6.

                 7.       Certain Restrictions.   So long as any share or
shares of Series A Preferred Stock are outstanding, the Corporation shall not,
without the affirmative vote of the holders of all of the shares of Series A
Preferred Stock at the time outstanding, take any of the following actions:

                 (a)      create or authorize any class or series of Capital
         Stock ranking prior to the Series A Preferred Stock with respect to
         the payment of dividends or the distribution of assets upon a
         Liquidation, or create or authorize any rights, options or warrants
         exercisable for, or securities convertible into or exchangeable for,
         shares of any such class or series of Capital Stock;

                 (b)      make any Restricted Payment at any time prior to the
         third anniversary of the Date of Original Issue of Series A Preferred
         Stock, if (i) after giving effect thereto, the Consolidated Net Worth
         of the Corporation and its consolidated subsidiaries would be less
         than $50,000,000 or (ii) in respect of any past quarterly dividend
         period or periods full dividends upon the outstanding shares of Series
         A Preferred Stock shall not have been paid;

                 (c)      enter into, or permit any Subsidiary to enter into,
         any Restricted Affiliate Transaction at any time prior to the third
         anniversary of the Date of Original Issue of Series A Preferred Stock,
         if (i) after giving effect thereto, the Consolidated Net Worth of the
         Corporation and its consolidated subsidiaries would be less than
         $50,000,000 or (ii)  in respect of any past quarterly dividend period

<PAGE>   6
                 (d)      merge or consolidate the Corporation with or into any
         other Person at any time prior to the third anniversary of the Date of
         Original Issue of Series A Preferred Stock, unless after giving effect
         to such merger or consolidation, the Consolidated Net Worth of the
         surviving or continuing Person in such merger or consolidation and its
         consolidated subsidiaries would be greater than or equal to the lesser
         of (i) $50,000,000 or (ii) the Consolidated Net Worth of the
         Corporation and its consolidated subsidiaries immediately prior to
         such merger or consolidation; or

                 (e)      merge or consolidate the Corporation with or into any
         other Person if the effect of such merger or consolidation would be to
         alter or affect adversely any rights, preferences or powers of the
         holders of Series A Preferred Stock.

                 8.       Amendment.  So long as any share or shares of Series
A Preferred Stock are outstanding, the Corporation shall not, without the
affirmative vote of the holders of all of the shares of Series A Preferred
Stock at the time outstanding, amend, alter or repeal any of the rights,
preferences or powers of the holders of shares of Series A Preferred Stock so
as to affect adversely any such rights, preferences or powers.

                 9.       Reacquired Shares.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of a new series
of Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to any conditions and restrictions set forth herein.

                 10.      Fractional Shares.  Series A Preferred Stock may be
issued in fractions of a share that shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Preferred Stock.


                          B.  SERIES B PREFERRED STOCK

                 RESOLVED, that the Board of Directors of the Corporation,
pursuant to the authority conferred upon it by the Amended and Restated
Articles of Incorporation of the Corporation and pursuant to the Reorganization
Plan, does hereby create and provide for the issue of a series of the Preferred
Stock, par value $.01 per share, of the Corporation and does hereby fix and
herein state the designation, preferences and relative and other special rights
of such series, and the qualifications, limitations and restrictions thereof,
as follows:

                 1.        Designation and Amount.  There is hereby created a
series of Preferred Stock designated as "Series B Preferred Stock."  The number
of shares constituting such series shall be 100,000.  Such number of shares may
be increased or decreased from time to time by





                                      -6-
<PAGE>   7
resolution of the Board of Directors; provided, however, that no decrease shall
reduce the number of shares of Series B Preferred Stock to a number less than
the number of shares of such series then issued and outstanding, plus the
number of shares of such series reserved for issuance upon the exercise of
outstanding rights, options or warrants or upon the conversion or exchange of
outstanding securities issued by the Corporation.

                 2.       Voting Rights.  In addition to any voting rights
granted to holders of Series B Preferred Stock pursuant to Sections 5 and 6
below, the holders of Series B Preferred Stock shall be entitled to vote as a
class as provided in this Section 2.  Whenever dividends of the Series B
Preferred Stock shall be in arrears in an amount equal to at least eight
quarterly dividends (whether or not consecutive), (i) the number of members of
the Board of Directors of the Corporation shall be increased by a number equal
to the current number of directors plus one, effective as of the time of
election of such directors as hereinafter provided, and (ii) the holders of the
Series B Preferred Stock (voting separately as a class) will have the exclusive
right to vote for and elect such number of additional directors, representing a
majority of the Board of Directors of the Corporation, at any meeting of
stockholders of the Corporation at which directors are to be elected held
during the period such dividends remain in arrears.  If the right to elect
directors shall have accrued to the holders of the Series B Preferred Stock
more than 90 days preceding the date established for the next annual meeting of
stockholders, the President of the Corporation shall, within 20 days after
delivery to the Corporation of a written request for a special meeting signed
by the holders of at least 10% of the shares of Series B Preferred Stock then
outstanding, call a special meeting of the holders of the Series B Preferred
Stock to be held within 60 days after the delivery of such request for the
purpose of electing such additional directors.  The right of the holders of the
Series B Preferred Stock to vote for such additional directors shall terminate
when all accrued and unpaid dividends on the Series B Preferred Stock have been
declared and paid or set apart for payment.  The term of office of all
directors so elected shall terminate immediately upon the termination of the
right of the holders of the Series B Preferred Stock to vote for such
additional directors.  The holders of the Series B Preferred Stock voting as a
class shall have the right to remove without cause at any time and replace any
directors such holders shall have elected pursuant to this Section 2.

                 3.       Dividends.

                 (a)      The holders of shares of Series B Preferred Stock

         Directors out of funds legally available therefor, cumulative cash
         dividends at a rate per annum equal to 6% of the Series B Liquidation
         Preference.  Accrued but unpaid dividends on Series B Preferred Stock
         shall not bear interest.

                 (b)      Dividends on shares of Series B Preferred Stock shall
         accrue from the Date of Original Issue of Series B Preferred Stock and
         shall be payable on each Quarterly Dividend Payment Date.

<PAGE>   8
                 (c)      Dividends declared by the Board of Directors shall be
         payable to the holders of shares of Series B Preferred Stock as their
         names shall appear on the stock transfer books of the Corporation on
         the fifth Business Day next preceding the applicable Quarterly
         Dividend Payment Date.  Dividends in arrears for any past quarterly
         dividend period or periods may be declared and paid to the holders of
         shares of Series B Preferred Stock at any time, without reference to
         any regular Quarterly Dividend Payment Date, as may be fixed by the
         Board of Directors.

                 (d)      Each share of Series B Preferred Stock shall rank
         junior to each share of Series A Preferred Stock but prior to each
         share of Junior Stock with respect to the payment of dividends.  If in
         respect of any past quarterly dividend period or periods full
         dividends upon the outstanding shares of Series B Preferred Stock
         shall not have been paid, the amount of the deficiency shall be fully
         paid or declared and set apart for payment before any dividend shall
         be paid or set apart for payment upon any shares of Junior Stock.

                 4.       Liquidation.  Each share of Series B Preferred Stock
shall rank junior to each share of Series A Preferred Stock but prior to each
share of Junior Stock with respect to the distribution of assets upon a
Liquidation.  In the event of any Liquidation, each holder of a share of Series
B Preferred Stock shall be entitled to receive, after payment of the Series A
Liquidation Preference to each holder of Series A Preferred Stock but before
any distribution shall be made to the holders of Junior Stock, an amount per
share equal to $1,000 (the "Series B Liquidation Preference"), plus an amount
equal to all accrued and unpaid dividends thereon, whether or not declared, to
the date of payment thereof.  In the event that there are not sufficient assets
available to permit payment in full of the Series B Liquidation Preference to
all holders of outstanding shares of Series B Preferred Stock, then the
remaining assets of the Corporation shall be distributed to the holders of this
series in proportion to the Series B Liquidation Preferences of the shares of
Series B Preferred Stock held by them.  After payment shall have been made in
full to the holders of the Series B Preferred Stock, the remaining assets and
funds of the Corporation shall be distributed among the holders of Junior Stock
according to their respective rights.

                 5.       Certain Restrictions.   So long as any share or
shares of Series B Preferred Stock are outstanding, the Corporation shall not,
without the affirmative vote of the holders of all of the shares of Series B
Preferred Stock at the time outstanding, voting separately as a class, create
or authorize any class or series of Capital Stock (other than the Series A
Preferred Stock created pursuant to these resolutions) ranking prior to the
Series B Preferred Stock with respect to the payment of dividends or the
distribution of assets upon a Liquidation, or create or authorize any rights,
options or warrants exercisable for, or securities convertible into or
exchangeable for, shares of any such class or series of Capital Stock.

                 6.       Amendment.  So long as any share or shares of Series
B Preferred Stock are outstanding, the Corporation shall not, without the
affirmative vote of the holders of at least a majority of the outstanding
shares of Series B Preferred Stock at the time outstanding, voting





                                      -8-
<PAGE>   9
separately as a class, amend, alter or repeal any of the rights, preferences or
powers of the holders of shares of Series B Preferred Stock so as to affect
adversely any such rights, preferences or powers.

                 7.       Reacquired Shares.  Any shares of Series B Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such shares shall upon their cancellation become authorized but
unissued shares of Preferred Stock and may be reissued as part of a new series
of Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to any conditions and restrictions set forth herein.

                 8.       Fractional Shares.  Series B Preferred Stock may be
issued in fractions of a share that shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
