ITEM 5.   OTHER EVENTS

          On June 24, 1996, Sanifill, Inc. ("Sanifill") issued a press release
announcing that it had entered into a definitive agreement (the "Agreement") for
the merger of a special purpose subsidiary of USA Waste Services, Inc. with and
into Sanifill, which, subject to stockholder approval and other conditions, will
result in Sanifill's becoming a wholly owned subsidiary of USA Waste Services,
Inc.  In the proposed merger, Sanifill stockholders will receive 1.7 shares of
USA Waste common stock for each Sanifill common share.  In connection with the
proposed merger, Sanifill and Chemical Bank entered into an amendment (the
"First Amendment") to the Company's 1991 Rights Agreement.  A copy of the press
release is attached hereto as Exhibit 99.1 and incorporated herein by reference.
A copy of the Agreement is attached hereto as Exhibit 99.2 and incorporated
herein by reference.  A copy of the First Amendment is attached hereto as
Exhibit 99.3 and incorporated herein by reference.

          Disclosure Regarding Forward Looking Statements. This Current Report 
on Form 8-K and the documents incorporated by reference herein (collectively, 
the "Report") contain "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. All statements other than statements of 
historical fact included in this Report are forward-looking statements, 
including without limitation: (a) the statement in the joint press release of 
Sanifill and USA Waste Services, Inc. dated June 24, 1996 (the "Press Release") 
regarding the anticipated closing date of the merger; (b) statements regarding 
the management and governance of the combined company; (c) the statement in the 
Press Release regarding the growth that will result from the ongoing acquisition
programs of both Sanifill and USA Waste; (d) the statements by John E. Drury in 
the Press Release regarding the significant benefits provided by the merger to 
stockholders of Sanifill and USA Waste; (e) the statements by Mr. Drury in the 
Press Release regarding the continuation of strong earnings growth of the 
combined company, the expectation of accretion to the earnings per share of USA 
Waste as a result of annual cost savings and operational synergies, the 
operational and financial strength of the combined entity, and the enhancement 
of USA Waste's capacity to benefit from growth opportunities in the industry; 
and (f) the statement by Lorne D. Bain in the Press Release regarding the 
synergies of the merger. Although Sanifill believes that the expectations 
reflected in such forward-looking statements are reasonable, it can give no 
assurance that such expectations will prove to have been correct. Important 
factors that could cause actual results to differ materially from Sanifill's 
expectations ("Cautionary Statements") include: (i) the timing and receipt of 
necessary approvals and other closing conditions for the merger; (ii) the 
ability of the combined entity to achieve administrative cost savings, 
rationalization of collection routes, insurance and bonding, cost reductions, 
lower interest expense and general economies of scale and generally to 
capitalize on the combined asset base and strategic position of the combined 
entity; and (iii) the actual results of the combined company which may be 
influenced by, among other things, the level and nature of competition from 
other waste companies, the current regulatory environment and the costs 
associated with such regulation, the availability of attractive acquisition 
opportunities, successful integration of acquired businesses, availability of 
working capital, ability to maintain margins and the management of costs in a 
changing regulatory environment. All related or subsequent written and oral 
forward-looking statements attributable to Sanifill or persons acting on its 
behalf are expressly qualified in their entirety by the Cautionary Statements.

                                 PRESS RELEASE


                             USA WASTE AND SANIFILL
                       JOINTLY ANNOUNCE MERGER AGREEMENT

          Houston, Texas (June 24, 1996) -- USA Waste Services, Inc. (NYSE --
"UW") and Sanifill, Inc. (NYSE -- "FIL") today jointly announced that the
companies have entered into a definitive merger agreement, approved by both
Boards of Directors, whereby Sanifill stockholders will receive 1.7 shares of
USA Waste common stock for each Sanifill common share.  USA Waste and Sanifill
have received opinions from independent financial advisors, Donaldson, Lufkin
and Jenrette Securities Corporation and Merrill Lynch and Co., respectively,
stating that the share exchange ratio is fair from a financial point of view to
their respective shareholders.  The closing of the merger is subject to approval
by both Companies' stockholders and certain lenders, Hart-Scott-Rodino antitrust
clearance, opinions that the merger will qualify as a tax-free pooling of
interests transaction and other standard and customary closing requirements.

          USA Waste's stock price closed Friday, June 21, 1996 at $27-7/8 per
share.  Based upon Sanifill's approximately 25.9 million outstanding shares and
share equivalents and existing

                                       1

indebtedness, the merger would be valued at about $1.6 billion.  The Companies
anticipate that the merger should close in the late summer or early fall.

          John E. Drury, Chairman and Chief Executive Officer of USA Waste, will
retain that position, and Rodney R. Proto, President, Chief Operating Officer
and Director of Sanifill will assume these positions at USA Waste.  Donald F.
Moorehead, Jr., Vice Chairman and Chief Development Officer, and Earl E.
DeFrates, Executive Vice President and Chief Financial Officer, will retain
these positions at USA Waste.  Mr. Proto and two designees from Sanifill's Board
will join USA Waste's Board, which will remain a twelve person board.

          Lorne D. Bain, Chairman and Chief Executive Officer of Sanifill, and
J. Chris Brewster, its Chief Financial Officer, will relinquish their posts, but
both will assist with merger transition matters.  David Sutherland-Yoest, USA
Waste's current President and Chief Operating Officer, will continue to serve
the Company as Regional Vice President of operations in the northeastern U.S.
and Canada, as well as being a Vice Chairman and Director of the Board.  In
connection with the merger, USA Waste will move its headquarters to Houston,
Texas.

          The combined Companies have annualized revenues of approximately $1.3
billion and total assets in excess of $2 billion.  Giving effect to the merger,
USA Waste, currently the third largest solid waste company in North America,
will have 108 collection operations, 83 landfills with total airspace of over
2.5 billion cubic gate yards, 45 transfer stations and 31 other operations,
serving over 1.7 million customers in 33 states, the District of Columbia,
Canada, Mexico and Puerto Rico. The ongoing acquisition programs of both
Companies will be continued during the pendency of the merger, resulting in
further growth.

                                       2

          Mr. Drury stated, "The combination of these two fine companies will
provide significant benefits to both stockholder groups.  We expect the combined
company to continue to reflect the strong earnings growth that each has
demonstrated over the past several years.  The merger is expected to be
immediately accretive to USA Waste's earnings per share as a result of
substantial annual cost savings and operational synergies which have been
identified.  Mr. Drury stated that, "the combined company will be strong
operationally and financially and have outstanding management talent at all
levels of the organization.  This combination will enhance USA Waste's capacity
to continue to benefit from the substantial growth opportunities that exist in
our industry."

          Mr. Bain said, "This merger is a thoroughly logical transaction, that
makes operating and financial sense across the board.  The synergies are
significant and sustainable, and the combined management team has the skills and
capabilities needed by a growth company in a consolidating industry.  This
merger will create North America's premier solid waste company, to the benefit
of employees, customers and stockholders."

          USA Waste, currently based in Dallas, Texas, is an integrated, non-
hazardous, solid waste management company serving municipal, commercial,
industrial and residential customers in 24 states.

          Sanifill, Inc., headquartered in Houston, Texas, is an environmental
services company specializing in the management and disposal of nonhazardous
waste in 23 states, the District of Columbia, the Commonwealth of Puerto Rico,

       WHEREAS, in connection with the Merger and as an inducement to the
Company to enter into this Agreement, the Company, Parent and the shareholders
of Parent listed on the Parent Disclosure Schedule (as defined in Article IV)

       NOW, THEREFORE, in consideration of the premises and the representations,
warranties, covenants and agreements contained herein, the parties hereto,
intending to be legally bound, agree as follows:


                                   ARTICLE I
                                   The Merger

     SECTION 1.1.   THE MERGER.  Upon the terms and subject to the conditions of
this Agreement, at the Effective Time (as defined in Section 1.2) in accordance
with the General Corporation Law of the State of Delaware (the "DGCL"),
Subsidiary shall be merged with and into the Company and the separate existence

effective at such time (the  "Effective Time") as shall be stated in a
certificate of merger, in a form mutually acceptable to Parent
<PAGE>
 
and the Company, to be filed with the Secretary of State of the State of
Delaware in accordance with the DGCL (the "Merger Filing").  The Merger Filing
shall be made simultaneously with or as soon as practicable after the closing of
the transactions contemplated by this Agreement in accordance with Section 3.5.
The parties acknowledge that it is their mutual desire and intent to consummate
the Merger as soon as practicable after the date hereof.  Accordingly, the
parties shall, subject to the provisions hereof and to the fiduciary duties of
their respective boards of directors, use all reasonable efforts to consummate,
as soon as practicable, the transactions contemplated by this Agreement in
accordance with Section 3.5.

     SECTION 2.1.   CERTIFICATE OF INCORPORATION.  The Certificate of
Incorporation of Subsidiary as in effect immediately prior to the Effective Time
shall be the Certificate of Incorporation of the Surviving Corporation after the
Effective Time, and thereafter may be amended in accordance with its terms and
as provided in the DGCL.

     SECTION 2.2.   BY-LAWS.  The By-laws of Subsidiary as in effect immediately

the Board of Directors of the Company shall take such action as may be necessary
to renominate Rodney R. Proto to the Board of Directors of the Company with a
term of office expiring in 2000 or thereafter.  All of the Company Designees

respective successors are duly elected or appointed and qualified.  One of the
Company Designees (to be designated by the Board of Directors of the Company

Directors to serve in accordance with the By-laws of Parent.

     (b) The directors of Subsidiary in office immediately prior to the
Effective Time shall be the directors of the Surviving Corporation after the

the Surviving Corporation until their respective successors are duly elected or
appointed and qualified.

     SECTION 2.4.   OFFICERS.   (a) Immediately following the Effective Time,

                                  ARTICLE III
                              Conversion of Shares

     SECTION 3.1.   CONVERSION OF COMPANY SHARES IN THE MERGER.  At the
Effective Time, by virtue of the Merger and without any action on the part of
any holder of any capital stock of Parent or the Company:

      (a) each share of the common stock, par value $.01 per share, of the
 Company (the "Company Common Stock") shall, subject to Sections 3.3 and 3.4, be
 converted into the right to receive, without interest, 1.70 (the "Exchange
 Ratio") shares of the common stock, par value $.01 per share, of Parent
 ("Parent Common Stock");

      (b) each share of capital stock of the Company, if any, owned by Parent or
 any subsidiary of Parent or held in treasury by the Company or any subsidiary
 of the Company immediately prior to the Effective Time shall be canceled and no
 consideration shall be paid in exchange therefor and shall cease to exist from
 and after the Effective Time; and

      (c)  subject to and as more fully provided in Section 7.9, each unexpired
 option or warrant to purchase Company Common Stock that is outstanding at the
 Effective Time, whether or not exercisable, shall automatically and without any
 action on the part of the holder thereof be converted into an option or warrant
 to purchase a number of shares of Parent Common Stock equal to the number of
 shares of Company Common Stock that could be purchased under such option or
 warrant multiplied by the Exchange Ratio, at a price per share of Parent Common
 Stock equal to the per share exercise price of such option or warrant divided
 by the Exchange Ratio.

     SECTION 3.2.   CONVERSION OF SUBSIDIARY SHARES.   At the Effective Time, by
virtue of the Merger and without any action on the part of Parent as the sole
stockholder of Subsidiary, each issued and outstanding share of common stock,
par value $.01 per share, of Subsidiary ("Subsidiary Common Stock") shall be
converted into one share of common stock, par value $.01 per share, of the
Surviving Corporation.

     SECTION 3.3.   EXCHANGE OF CERTIFICATES.  (a) From and after the Effective
Time, each holder of an outstanding certificate which immediately prior to the
Effective Time represented shares of Company Common Stock shall be entitled to
receive in exchange therefor, upon surrender thereof to an exchange agent
reasonably satisfactory to Parent and the Company (the "Exchange Agent"), a
certificate or certificates representing the number of whole shares of Parent
Common Stock to which such holder is entitled pursuant to Section 3.1(a).
Notwithstanding any other provision of this Agreement, (i) until holders or
transferees of certificates theretofore representing shares of Company Common
Stock have surrendered them for exchange as provided herein, no dividends shall
be paid with respect to any shares represented by such certificates and

                                     Page 3
<PAGE>
 
no payment for fractional shares shall be made and (ii) without regard to when
such certificates representing shares of Company Common Stock are surrendered
for exchange as provided herein, no interest shall be paid on any dividends or
any payment for fractional shares.  Upon surrender of a certificate which
immediately prior to the Effective Time represented shares of Company Common
Stock, there shall be paid to the holder of such certificate the amount of any
dividends which theretofore became payable, but which were not paid by reason of
the foregoing, with respect to the number of whole shares of Parent Common Stock
represented by the certificate or certificates issued upon such surrender.

     (b) If any certificate for shares of Parent Common Stock is to be issued in
a name other than that in which the certificate for shares of Company Common
Stock surrendered in exchange therefor is registered, it shall be a condition of
such exchange that the person requesting such exchange shall pay any applicable
transfer or other taxes required by reason of such issuance.

     (c) Promptly after the Effective Time, Parent shall make available to the
Exchange Agent the certificates representing shares of Parent Common Stock
required to effect the exchanges referred to in paragraph (a) above and cash for
payment of any fractional shares referred to in Section 3.4.

     (d) Promptly after the Effective Time, the Exchange Agent shall mail to
each holder of record of a certificate or certificates that immediately prior to
the Effective Time represented outstanding shares of Company Common Stock (the
"Company Certificates") (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Company
Certificates shall pass, only upon actual delivery of the Company Certificates
to the Exchange Agent) and (ii) instructions for use in effecting the surrender
of the Company Certificates in exchange for certificates representing shares of
Parent Common Stock.  Upon surrender of Company Certificates for cancellation to
the Exchange Agent, together with a duly executed letter of transmittal and such
other documents as the Exchange Agent shall reasonably require, the holder of
such Company Certificates shall be entitled to receive in exchange therefor a
certificate representing that number of whole shares of Parent Common Stock into
which the shares of Company Common Stock theretofore represented by the Company
Certificates so surrendered shall have been converted pursuant to the provisions
of Section 3.1(a), and the Company Certificates so surrendered shall be
canceled.  Notwithstanding the foregoing, neither the Exchange Agent nor any
party hereto shall be liable to a holder of shares of Company Common Stock for
any shares of Parent Common Stock or dividends or distributions thereon
delivered to a public official pursuant to applicable abandoned property,
escheat or similar laws.

     (e) Promptly following the date which is nine months after the Effective
Date, the Exchange Agent shall deliver to Parent all cash, certificates
(including any Parent Common Stock) and other documents in its possession
relating to the transactions described in this Agreement, and the Exchange
Agent's duties shall terminate.  Thereafter, each holder of a Company
Certificate may surrender such Company Certificate to the Surviving Corporation
and (subject to applicable abandoned property, escheat and similar laws) receive
in exchange therefor the Parent Common Stock, without any interest thereon.
Notwithstanding the foregoing, none of the Exchange Agent, Parent, Subsidiary,
the Company or the Surviving Corporation shall be liable to a holder of shares
of Company Common Stock for any shares of Parent Common Stock delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

     (f)  In the event any Company Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Company Certificate to be lost, stolen or destroyed, the Surviving
Corporation shall issue in exchange for such lost, stolen or destroyed Company
Certificate the

                                     Page 4
<PAGE>
 
Parent Common Stock deliverable in respect thereof determined in accordance with
this Article III.  When authorizing such issuance in exchange therefor, the
Board of Directors of the Surviving Corporation may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed Company Certificate to give the Surviving Corporation such
indemnity as it may reasonably direct as protection against any claim that may
be made against the Surviving Corporation with respect to the Company
Certificate alleged to have been lost, stolen or destroyed.

     SECTION 3.4.   NO FRACTIONAL SECURITIES.  Notwithstanding any other
provision of this Agreement, no certificates or scrip for fractional shares of
Parent Common Stock shall be issued in the Merger and no Parent Common Stock
dividend, stock split or interest shall relate to any fractional security, and
such fractional interests shall not entitle the owner thereof to vote or to any
other rights of a security holder.  In lieu of any such fractional shares, each
holder of shares of Company Common Stock who would otherwise have been entitled
to receive a fraction of a share of Parent Common Stock upon surrender of
Company Certificates for exchange pursuant to this Article III shall be entitled
to receive from the Exchange Agent a cash payment equal to such fraction
multiplied by the average closing price per share of Parent Common Stock on the
New York Stock Exchange, as reported by the Wall Street Journal, during the 10
trading days immediately preceding the Effective Time.

     SECTION 3.5.   CLOSING.  The closing (the "Closing") of the transactions
contemplated by this Agreement shall take place at a location mutually agreeable
to Parent and the Company as promptly as practicable following the date on which
the last of the conditions set forth in Article VIII is fulfilled or waived, or
at such other time and place as Parent and the Company shall agree.  The date on
which the Closing occurs is referred to in this Agreement as the "Closing Date."

     SECTION 3.6.   CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At and after the
Effective Time, holders of Company Certificates shall cease to have any rights
as stockholders of the Company, except for the right to receive shares of Parent
Common Stock pursuant to Section 3.1 and the right to receive cash for payment
of fractional shares pursuant to Section 3.4.  At the Effective Time, the stock
transfer books of the Company shall be closed and no transfer of shares of
Company Common Stock which were outstanding immediately prior to the Effective
Time shall thereafter be made.  If, after the Effective Time, subject to the
terms and conditions of this Agreement, Company Certificates formerly
representing shares of Company Common Stock are presented to the Surviving
Corporation, they shall be canceled and exchanged for shares of Parent Common
Stock in accordance with this Article III.


                                   ARTICLE IV
                         Representations and Warranties
                            of Parent and Subsidiary

     Parent and Subsidiary each represent and warrant to the Company that,
except as set forth in the Disclosure Schedule dated as of the date hereof and
signed by an authorized officer of Parent (the "Parent Disclosure Schedule"),
each of which exceptions shall specifically identify the relevant Section hereof
to which it relates:

     SECTION 4.1.   ORGANIZATION AND QUALIFICATION.  Each of Parent and
Subsidiary is a corporation duly organized, validly existing and in good
standing under the laws of the state of its incorporation and has the requisite
power and authority to own, lease and operate its assets and properties and to
carry on its

                                     Page 5
<PAGE>
 
business as it is now being conducted.  Each of Parent and Subsidiary is
qualified to do business and is in good standing in each jurisdiction in which
the properties owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to
be so qualified and in good standing will not, when taken together with all
other such failures, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
Parent and its subsidiaries, taken as a whole.  True, accurate and complete
copies of each of Parent's and Subsidiary's charters and By-laws, in each case
as in effect on the date hereof, including all amendments thereto, have
heretofore been delivered to the Company.

     SECTION 4.2.   CAPITALIZATION.  (a) As of June 15, 1996, the authorized
capital stock of Parent consisted of 150,000,000 shares of Parent Common Stock
and 10,000,000 shares of preferred stock, par value $.01 per share ("Parent
Preferred Stock").  As of June 15, 1996, (i) 88,330,623 shares of Parent Common
Stock were issued and outstanding, all of which were validly issued and are
fully paid, nonassessable and free of preemptive rights, (ii) no shares of
Parent Preferred Stock were issued and outstanding, (iii) 26,310 shares of
Parent Common Stock and no shares of Company Preferred Stock were held in the
treasury of Parent and (iv) 13,136,521 shares of Parent Common Stock were
reserved for issuance pursuant to the exercise of outstanding options and
warrants to purchase Parent Common Stock.  Assuming the exercise of all
outstanding options and warrants to purchase Parent Common Stock, as of June 15,
1996, there would be 101,467,144 shares of Parent Common Stock issued and
outstanding.  In addition, as of June 15, 1996, 4,364,152 shares of Parent
Common Stock were reserved and unissued pending conversion of shares of acquired
companies.

     (b) The authorized capital stock of Subsidiary consists of 1,000 shares of
Subsidiary Common Stock, of which 100 shares are issued and outstanding, which
shares are owned beneficially and of record by Parent.

     (c) Except as disclosed in the Parent SEC Reports (as defined in Section
4.5), as of the date hereof, there are no outstanding subscriptions, options,
calls, contracts, commitments, understandings, restrictions, arrangements,
rights or warrants, including any right of conversion or exchange under any
outstanding security, instrument or other agreement and also including any
rights plan or other anti-takeover agreement, obligating Parent or any
subsidiary of Parent to issue, deliver or sell, or cause to be issued, delivered
or sold, additional shares of the capital stock of Parent or obligating Parent
or any subsidiary of Parent to grant, extend or enter into any such agreement or
commitment.  Except as otherwise disclosed in the Parent SEC Reports, there are
no voting trusts, proxies or other agreements or understandings to which Parent
or any subsidiary of Parent is a party or is bound with respect to the voting of
any shares of capital stock of Parent other than voting agreements executed  in
connection with this Agreement.  The Shareholders Agreement dated as of December
18, 1995 between Parent and Donald F. Moorehead, Jr., John E. Drury, John G.
Rangos, Sr., John G. Rangos, Jr., Alexander W. Rangos and John Rangos
Development Corporation, Inc. has been terminated in connection with the
execution of this Agreement.  The shares of Parent Common Stock issued to
stockholders of the Company in the Merger will be at the Effective Time duly
authorized, validly issued, fully paid and nonassessable and free of preemptive
rights.

     SECTION 4.3.   SUBSIDIARIES.  Each direct and indirect corporate subsidiary
of Parent is duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation and has the requisite power and
authority to own, lease and operate its assets and properties and to carry on
its business as it is now being conducted.  Each subsidiary of Parent is
qualified to do business, and is in good standing, in each jurisdiction in which
the properties owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to
be so qualified and

                                     Page 6
<PAGE>
 
in good standing would not, when taken together with all such other failures,
have a material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of Parent and its
subsidiaries, taken as a whole.  All of the outstanding shares of capital stock
of each corporate subsidiary of Parent are validly issued, fully paid,
nonassessable and free of preemptive rights, and are owned directly or
indirectly by Parent, free and clear of any liens, claims or encumbrances,
except that such shares are pledged to secure Parent's credit facilities.  There
are no subscriptions, options, warrants, rights, calls, contracts, voting
trusts, proxies or other commitments, understandings, restrictions or
arrangements relating to the issuance, sale, voting, transfer, ownership or
other rights with respect to any shares of capital stock of any corporate
subsidiary of Parent, including any right of conversion or exchange under any
outstanding security, instrument or agreement.  As used in this Agreement, the
term "subsidiary" shall mean, when used with reference to any person or entity,
any corporation, partnership, joint venture or other entity of which such person
or entity (either acting alone or together with its other subsidiaries) owns,
directly or indirectly, 50% or more of the stock or other voting interests, the
holders of which are entitled to vote for the election of a majority of the
board of directors or any similar governing body of such corporation,
partnership, joint venture or other entity.

     SECTION 4.4.   AUTHORITY; NON-CONTRAVENTION; APPROVALS.  (a)  Parent and
Subsidiary each have full corporate power and authority to enter into this
Agreement and, subject to the Parent Stockholders' Approval (as defined in
Section 7.3(b)) and the Parent Required Statutory Approvals (as defined in
Section 4.4(c)), to consummate the transactions contemplated hereby.  This
Agreement has been approved by the Boards of Directors of Parent and Subsidiary,
and no other corporate proceedings on the part of Parent or Subsidiary are
necessary to authorize the execution and delivery of this Agreement or, except
for the Parent Stockholders' Approval, the consummation by Parent and Subsidiary
of the transactions contemplated hereby.  This Agreement has been duly executed
and delivered by each of Parent and Subsidiary, and, assuming the due
authorization, execution and delivery hereof by the Company, constitutes a valid
and legally binding agreement of each of Parent and Subsidiary enforceable
against each of them in accordance with its terms, except that such enforcement
may be subject to (i) bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting or relating to enforcement of creditors' rights
generally and (ii) general equitable principles.  Without limitation of the
foregoing, each of the covenants and obligations of Parent set forth in Sections
6.2, 7.1, 7.2, 7.3, 7.6, 7.7, 7.8, 7.10 and 7.12 is valid, legally binding and
enforceable (subject as aforesaid) notwithstanding the absence of the Parent
Stockholders' Approval.

     (b) The execution and delivery of this Agreement by each of Parent and
Subsidiary do not violate, conflict with or result in a breach of any provision
of, or constitute a default (or an event which, with notice or lapse of time or
both, would constitute a default) under, or result in the termination of, or
accelerate the performance required by, or result in a right of termination or
acceleration under, or result in the creation of any lien, security interest,
charge or encumbrance upon any of the properties or assets of Parent or any of
its subsidiaries under any of the terms, conditions or provisions of (i) the
respective charters or by-laws of Parent or any of its subsidiaries, (ii) any
statute, law, ordinance, rule, regulation, judgment, decree, order, injunction,
writ, permit or license of any court or governmental authority applicable to
Parent or any of its subsidiaries or any of their respective properties or
assets or (iii) any note, bond, mortgage, indenture, deed of trust, license,
franchise, permit, concession, contract, lease or other instrument, obligation
or agreement of any kind to which Parent or any of its subsidiaries is now a
party or by which Parent or any of its subsidiaries or any of their respective
properties or assets may be bound or affected.  The consummation by Parent and
Subsidiary of the transactions contemplated hereby will not result in any
violation, conflict, breach, termination, acceleration or creation of liens
under any of the terms, conditions or provisions described in clauses (i)
through (iii) of the preceding sentence, subject (x) in the case of the terms,
conditions

                                     Page 7
<PAGE>
 
or provisions described in clause (ii) above, to obtaining (prior to the
Effective Time) the Parent Required Statutory Approvals and the Parent
Stockholder's Approval and (y) in the case of the terms, conditions or
provisions described in clause (iii) above, to obtaining (prior to the Effective
Time) consents required from commercial lenders, lessors or other third parties
as specified on the Parent Disclosure Schedule.  Excluded from the foregoing
sentences of this paragraph (b), insofar as they apply to the terms, conditions
or provisions described in clauses (ii) and (iii) of the first sentence of this
paragraph (b), are such violations, conflicts, breaches, defaults, terminations,
accelerations or creations of liens, security interests, charges or encumbrances
that would not, in the aggregate, have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) results
of operations of Parent and its subsidiaries, taken as a whole.

     (c) Except for (i) the filings by Parent required by the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), (ii) the filing

Parent and its subsidiaries, taken as a whole.

     SECTION 4.5.   REPORTS AND FINANCIAL STATEMENTS.  Since January 1, 1994,

operations of Parent and its subsidiaries, taken as a whole, or (ii) have been
discharged or paid in full prior to the date hereof; and (c) liabilities and

mailing date, comply as to form in all material respects with all applicable
laws, including the provisions of the Securities Act and the Exchange Act and
the rules and regulations promulgated thereunder, except that no representation
is made by Parent or Subsidiary with respect to information supplied by the

could not reasonably be expected to have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) or
results of operations of Parent and its subsidiaries, taken as a whole.  Except
as disclosed in the Parent SEC Reports, as of the date of this Agreement, to the
knowledge of Parent, no investigation or review by any governmental or
regulatory body or authority is pending or threatened, nor has any governmental

be foreseen, will not have a material adverse effect on the business,
operations, properties, assets, condition (financial or other) or results of
operations of Parent and its subsidiaries, taken as a whole.  Parent and its
subsidiaries have all permits, licenses, franchises, variances, exemptions,
orders and other governmental authorizations, consents and approvals necessary
to conduct their businesses as presently conducted (collectively, the "Parent
Permits"), except for permits, licenses, franchises, variances, exemptions,
orders, authorizations, consents and approvals the absence of which, alone or in
the aggregate, would not have a material adverse effect on the business,
operations, properties, assets, condition (financial or other) or results of
operations of Parent and its subsidiaries, taken as a whole.  Parent and its
subsidiaries are not in violation of the terms of any Parent Permit, except for
delays in filing reports or violations which, alone or in the aggregate, would
not have a material adverse effect on the business, operations, properties,
assets, condition (financial or other) or results of operations of Parent and
its subsidiaries, taken as a whole.

     SECTION 4.11.  COMPLIANCE WITH AGREEMENTS.  Except as disclosed in the
Parent SEC Reports, Parent and each of its subsidiaries are not in breach or
violation of or in default in the performance or observance of any term or
provision of, and no event has occurred which, with lapse of time or action by a
third party, could result in a default under (a) the respective charter, by-laws
or other similar organizational instruments of Parent or any of its subsidiaries
or (b) any contract, commitment, agreement, indenture, mortgage, loan agreement,
note, lease, bond, license, approval or other instrument to which Parent or any
of its subsidiaries is a party or by which any of them is bound or to which any
of their property is subject, other than, in the case of clause (b) of this
Section 4.11, breaches, violations and defaults which would not have, in the

assets, condition (financial or other) or results of operations of Parent and
its subsidiaries, taken as a whole.

with the appropriate governmental authorities all Tax Returns (as defined in
Section 4.12(c)) required to be filed by them for all periods ending on or prior
to the Effective Time, other than those Tax Returns the failure of which to file

                                    Page 10
<PAGE>
 
would not have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
Parent and its subsidiaries, taken as a whole, and such Tax Returns are true,
correct and complete in all material respects and (ii) duly paid in full or made
adequate provision for the payment of all Taxes (as defined in Section 4.12(b))

reflected in the Parent balance sheet included in the latest Parent SEC Report
are adequate to cover all Taxes for all periods ending at or prior to the date
of such balance sheet and there is no liability for Taxes for any period
beginning after such date other than Taxes arising in the ordinary course of
business.  There are no material liens for Taxes upon any property or assets of
Parent or any subsidiary thereof, except for liens for Taxes not yet due.  There
are no unresolved issues of law or fact arising out of a notice of deficiency,
proposed deficiency or assessment from the Internal Revenue Service (the "IRS")
or any other governmental taxing authority with respect to Taxes of the Parent
or any of its subsidiaries which, if decided adversely, singly or in the
aggregate, would have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
Parent and its subsidiaries, taken as a whole.  Neither Parent nor its
subsidiaries has waived any statute of limitations in respect of Taxes or agreed
to any extension of time with respect to a Tax assessment or deficiency other
than waivers and extensions which are no longer in effect.  Neither Parent nor
any of its subsidiaries is a party to any agreement providing for the allocation
or sharing of Taxes with any entity that is not, directly or indirectly, a

consequences of which are fully and adequately reserved for in the Parent
Financial Statements.  Neither Parent nor any of its corporate subsidiaries has,
with regard to any assets or property held, acquired or to be acquired by any of
them, filed a consent to the application of Section 341(f) of the Code.

                 Representations and Warranties of the Company

     The Company represents and warrants to Parent and Subsidiary that, except
as set forth in the disclosure schedule dated as of the date hereof and signed
by an authorized officer of the Company (the "Company Disclosure Schedule"),
each of which exceptions shall specifically identify the relevant Section hereof
to which it relates:

     SECTION 5.1.   ORGANIZATION AND QUALIFICATION.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has the requisite corporate power and authority to
own, lease and operate its assets and properties and to carry on its business as
it is now being conducted.  The Company is qualified to do business and is in
good standing in each jurisdiction in which the properties owned, leased or
operated by it or the nature of the business conducted by it makes such
qualification necessary, except where the failure to be so qualified and in good
standing will not, when taken together with all other such failures, have a
material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of the Company and its
subsidiaries, taken as a whole.  True, accurate and complete copies of the
Company's Articles of Incorporation and By-laws, in each case as in effect on
the date hereof, including all amendments thereto, have heretofore been
delivered to Parent.

     SECTION 5.2.   CAPITALIZATION.  (a) The authorized capital stock of the
Company consists of 100,000,000 shares of Company Common Stock and 500,000
shares of preferred stock, par value $10.00 per share ("Company Preferred
Stock").  As of June 15, 1996, (i) 25,030,471 shares of Company Common Stock
were issued and outstanding, all of which were validly issued and are fully
paid, nonassessable and free of preemptive rights, (ii) no shares of Company
Common Stock and no shares of Company Preferred Stock were held in the treasury
of the Company, (iii) 1,001,866 shares of Company Common Stock were reserved for
issuance upon exercise of options issued and outstanding pursuant to the
Company's 1989 Stock Option Plan, as amended, (iv) 1,461,360 shares of Company
Common Stock were reserved for issuance upon exercise of options issued and
outstanding pursuant to the Company's 1994 Long-Term Incentive Plan, (v) 607,266
shares of Company Common Stock were reserved for issuance pursuant to the
Company's 1991 Employee Stock Purchase Plan, (vi) 2,389,610 shares of Company
Common Stock were reserved for issuance upon conversion of outstanding
convertible debentures of the Company, (vii) 103,264 shares of Company Common
Stock were reserved for issuance upon exercise of outstanding warrants, (viii)
no shares of Company Preferred Stock were issued and outstanding and (ix) 83,435
shares of Company Preferred Stock were reserved for issuance upon exercise of
Rights ("Preferred Stock Purchase Rights") issued pursuant to that certain
Rights Agreement dated as of December 1, 1991 between the Company and First
City, Texas -Houston, N.A., a national banking association, as amended by
Amendment No. 1 thereto between the Company and Chemical Bank, a New York State
banking corporation, (the "Preferred Stock Rights Agreement").  Except as set
forth in the preceding sentence, no other Awards (as such term is defined in the
Company's 1994 Long-Term Incentive Plan) were issued and outstanding as of June
15, 1996.  A true and correct copy of the Preferred Stock Rights Agreement has
been made available to Parent.  Assuming conversion of all outstanding
convertible debentures of the Company and the exercise of all outstanding
options, warrants or rights (other than the Preferred Stock Purchase Rights
issued under the Preferred Stock Rights Agreement) to purchase Company Common
Stock, as of June 15, 1996, there would be 29,988,071 shares of Company Common
Stock issued and outstanding.

     (b) Except as disclosed in the Company SEC Reports (as defined in Section
5.5), as of the date hereof there were no outstanding subscriptions, options,
calls, contracts, commitments, understandings, restrictions, arrangements,
rights or warrants, including any right of conversion or exchange under any
outstanding security, instrument or other agreement and also including any
rights plan or other anti-takeover agreement, obligating the Company or any
subsidiary of the Company to issue, deliver or sell, or cause to be issued,
delivered or sold, additional shares of the capital stock of the Company or
obligating the Company or any subsidiary of the Company to grant, extend or
enter into any such agreement or commitment.  There are no voting trusts,
proxies or other agreements or understandings to which the Company or any
subsidiary of the Company is a party or is bound with respect to the voting of
any shares of capital stock of the Company other than voting agreements executed
in connection with this Agreement.

     SECTION 5.3.   SUBSIDIARIES.   Each direct and indirect corporate
subsidiary of the Company is duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has the
requisite power and authority to own, lease and operate its assets and
properties and to carry on its business as it is now being conducted.  Each
subsidiary of the Company is qualified to do business, and is in good standing,
in each jurisdiction in which the properties owned, leased or operated by it or
the nature of the business conducted by it makes such qualification necessary,
except where the failure to be so qualified and in good standing will not, when
taken together with all such other failures, have a material adverse effect on
the business, operations, properties, assets, condition (financial or other) or
results of operations of the Company and its subsidiaries, taken as a whole.
All of the outstanding shares of capital stock of each corporate subsidiary of
the Company are validly issued, fully paid, nonassessable and free of preemptive
rights and are owned directly or indirectly by the Company free and clear of any
liens, claims, encumbrances, security interests, equities, charges and options
of any nature whatsoever.  There are no subscriptions, options, warrants,
rights, calls, contracts, voting trusts, proxies or other commitments,
understandings, restrictions or arrangements relating to the issuance, sale,
voting, transfer, ownership or other rights with respect to any shares of
capital stock of any corporate subsidiary of the Company, including any right of
conversion or exchange under any outstanding security, instrument or agreement.

     SECTION 5.4.   AUTHORITY; NON-CONTRAVENTION; APPROVALS.   (a)  The Company
has full corporate power and authority to enter into this Agreement and, subject
to the Company Stockholders' Approval (as defined in Section 7.3(a)) and the
Company Required Statutory Approvals (as defined in Section 5.4(c)), to
consummate the transactions contemplated hereby.  The Board of Directors of the
Company has at a meeting duly called and held and at which a quorum was present
and acting throughout, by the requisite affirmative vote of the directors of the
Company, (i) determined that the Merger is in the best interests of the Company
and its stockholders, (ii) approved this Agreement and the Merger and (iii)
determined that such approval satisfies the requirements of subparagraph A.2 of
Article Eighth of the Company's Certificate of Incorporation and, as a result,
renders inapplicable to the Merger and this Agreement the other provisions of
paragraph A of Article Eighth.  No other corporate proceedings on the part of
the Company are necessary to authorize the execution and delivery of this
Agreement or, except for the Company Stockholders' Approval, the consummation by
the Company of the transactions contemplated hereby.  This Agreement has been
duly executed and delivered by the Company, and, assuming the due authorization,
execution and delivery hereof by Parent and Subsidiary, constitutes a valid and
legally binding agreement of the Company, enforceable against the Company in
accordance with its terms, except that such enforcement may be subject to (a)
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting or relating to enforcement of creditors' rights generally and (b)
general equitable principles. Without limitation of the foregoing, each of the
covenants and obligations of the Company set forth in

                                    Page 17
<PAGE>
 
Sections 6.1, 6.5, 7.1, 7.2, 7.3, 7.6, 7.7, 7.8, 7.10, 7.12 and 7.14 is valid,
legally binding and enforceable (subject as aforesaid) notwithstanding the
absence of the Company Stockholders' Approval.

     (b) The execution and delivery of this Agreement by the Company do not
violate, conflict with or result in a breach of any provision of, or constitute
a default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination of, or accelerate the
performance required by, or result in a right of termination or acceleration
under, or result in the creation of any lien, security interest, charge or
encumbrance upon any of the properties or assets of the Company or any of its
subsidiaries under any of the terms, conditions or provisions of (i) the
respective charters or by-laws of the Company or any of its subsidiaries, (ii)
any statute, law, ordinance, rule, regulation, judgment, decree, order,
injunction, writ, permit or license of any court or governmental authority
applicable to the Company or any of its subsidiaries or any of their respective
properties or assets, or (iii) any note, bond, mortgage, indenture, deed of
trust, license, franchise, permit, concession, contract, lease or other
instrument, obligation or agreement of any kind to which the Company or any of
its subsidiaries is now a party or by which the Company or any of its
subsidiaries or any of their respective properties or assets may be bound or
affected. The consummation by the Company of the transactions contemplated
hereby will not result in any violation, conflict, breach, termination,
acceleration or creation of liens under any of the terms, conditions or
provisions described in clauses (i) through (iii) of the preceding sentence,
subject (x) in the case of the terms, conditions or provisions described in
clause (ii) above, to obtaining (prior to the Effective Time) the Company
Required Statutory Approvals and the Company Stockholders' Approval and (y) in
the case of the terms, conditions or provisions described in clause (iii) above,
to obtaining (prior to the Effective Time) consents required from commercial
lenders, lessors or other third parties as specified in the Company Disclosure
Schedule.  Excluded from the foregoing sentences of this paragraph (b), insofar
as they apply to the terms, conditions or provisions described in clauses (ii)
and (iii) of the first sentence of this paragraph (b), are such violations,
conflicts, breaches, defaults, terminations, accelerations or creations of
liens, security interests, charges or encumbrances that would not, in the
aggregate, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
the Company and its subsidiaries, taken as a whole.

     (c)  Except for (i) the filings by the Company required by the HSR Act,
(ii) the filing of the Joint Proxy Statement/Prospectus with the SEC pursuant to
the Exchange Act, (iii) the making of the Merger Filing with the Secretary of
State of the State of Delaware in connection with the Merger and (iv) any

referred to as the "Company Required Statutory Approvals"), no declaration,
filing or registration with, or notice to, or authorization, consent or approval
of, any governmental or regulatory body or authority is necessary for the
execution and delivery of this Agreement by the Company or the consummation by
the Company of the transactions contemplated hereby, other than such
declarations, filings, registrations, notices, authorizations, consents or
approvals which, if not made or obtained, as the case may be, would not, in the
aggregate, have a material adverse effect on the business, operations,
properties, assets, condition (financial or other) or results of operations of
the Company and its subsidiaries, taken as a whole.

     SECTION 5.5. REPORTS AND FINANCIAL STATEMENTS. Since January 1, 1994,

subsidiaries operate generally.

     SECTION 5.8.   LITIGATION.  Except as referred to in the Company SEC
Reports, there are no claims, suits, actions or proceedings pending or, to the
knowledge of the Company, threatened against, relating to or affecting the
Company or any of its subsidiaries, before any court, governmental department,

operations of the Company and its subsidiaries, taken as a whole. Except as
referred to in the Company SEC Reports, neither the Company nor any of its
subsidiaries is subject to any judgment, decree, injunction, rule or order of
any court, governmental department, commission, agency, instrumentality or
authority, or any arbitrator which prohibits or restricts the consummation of
the transactions contemplated hereby or would have any material adverse effect
on the business, operations, properties, assets, condition (financial or other)
or results of operations of the Company and its subsidiaries, taken as a whole.

     SECTION 5.9.   REGISTRATION STATEMENT AND PROXY STATEMENT.  None of the
information to be supplied by the Company or its subsidiaries for inclusion in
(a) the Registration Statement or (b) the Proxy Statement will, in the case of
the Proxy Statement or any amendments thereof or supplements thereto, at the
time of the mailing of the Proxy Statement and any amendments or supplements

thereunder, except that no representation is made by the Company with respect to
information supplied by Parent, Subsidiary or any stockholder of Parent for
inclusion therein.

     SECTION 5.10.  NO VIOLATION OF LAW.  Except as disclosed in the Company SEC
Reports, neither the Company nor any of its subsidiaries is in violation of or
has been given notice or been charged with any violation of, any law, statute,
order, rule, regulation, ordinance or judgment (including, without limitation,
any applicable environmental law, ordinance or regulation) of any governmental
or regulatory body or authority, except for violations which, in the aggregate,
could not reasonably be expected to have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) or
results of operations of the Company and its subsidiaries, taken as a whole.
Except as disclosed in the Company SEC Reports, as of the date of this
Agreement, to the knowledge of the Company, no investigation or review by any
governmental or regulatory body or authority is pending or threatened, nor has
any governmental or regulatory body or authority indicated an intention to
conduct the same, other than, in each case, those the outcome of which, as far
as reasonably can be foreseen, will not have a material adverse effect on the
business, operations, properties, assets, condition (financial or other) or
results of operations of the Company and its subsidiaries, taken as a whole.
The Company and its subsidiaries have all permits, licenses, franchises,
variances, exemptions, orders and other governmental authorizations, consents
and approvals necessary to conduct their businesses as presently conducted
(collectively, the "Company Permits"), except for permits, licenses, franchises,
variances, exemptions, orders, authorizations, consents and approvals the
absence of which, alone or in the aggregate, would not have a material adverse
effect on the business, operations, properties, assets, condition (financial or
other) or results of operations of the Company and its subsidiaries, taken as a
whole.  The Company and its subsidiaries are not in violation of the terms of
any Company Permit, except for delays in filing reports or violations which,

laws or similar organizational instruments of the Company or any of its
subsidiaries or (b) any contract, commitment, agreement, indenture, mortgage,
loan agreement, note, lease, bond, license, approval or other instrument to
which the Company or any of its subsidiaries is a party or by which any of them
is bound or to which any of their property is subject, other than, in the case
of clause (b) of this Section 5.11, breaches, violations and defaults which
would not have, in the aggregate, a material adverse effect on the business,
operations, properties, assets, condition (financial or other) or results of
operations of the Company and its subsidiaries, taken as a whole.

     SECTION 5.12.  TAXES.   The Company and its subsidiaries have (i) duly
filed with the appropriate governmental authorities all Tax Returns required to
be filed by them for all periods ending on or prior to the Effective Time, other

adverse effect on the business, operations, properties, assets, condition
(financial or other) or results of operations of the Company and its
subsidiaries, taken as a whole, and such Tax Returns are true, correct and
complete in all material respects, and (ii) duly paid in full or made adequate
provision for the payment of all Taxes for all past and current periods.  The
liabilities and reserves for Taxes reflected in the Company balance sheet
included in the latest Company SEC Report are adequate to cover all Taxes for
all periods ending at or prior to the date of such balance sheet and there is no

properties, assets, condition (financial or other) or results of operations of
the Company and its subsidiaries, taken as a whole.  Neither the Company nor its
subsidiaries has waived any statute of limitations in respect of Taxes or agreed
to any extension of time with respect to a Tax assessment or deficiency other
than waivers and extensions which are no longer in effect. Neither the Company
nor any of its subsidiaries is a party to any agreement providing for the
allocation or sharing of Taxes with any entity that is not, directly or
indirectly, a wholly-owned corporate subsidiary of Company other than agreements
the consequences of which are fully and adequately reserved for in the Company
Financial Statements.  Neither the Company nor any of its corporate subsidiaries

any of them, filed a consent to the application of Section 341(f) of the Code.

     SECTION 5.13.  EMPLOYEE BENEFIT PLANS; ERISA.  (a) Except as disclosed in
the Company SEC Reports, at the date hereof, the Company and its subsidiaries do

collective bargaining agreements or to comply with applicable law.

prohibited transactions within the meaning of Section 406 or 407 of ERISA or

Plans which is subject to Title IV of ERISA did not, as of its latest valuation
date, exceed the then current value of the assets of such plan allocable to such

SEC Reports as of March 31, 1996, based upon reasonable actuarial assumptions
currently utilized for such Company Plan, (vi) each of the Company Plans has
been operated and administered in all material respects in accordance with

"qualified" status of such Company Plans, and the period for making any such
necessary retroactive amendments has not expired, (viii) with respect to Multi-
employer Plans, neither the Company nor any of its subsidiaries has made or
suffered a "complete withdrawal" or a  "partial withdrawal," as such terms are

expected to occur which presents a material risk of a complete or partial
withdrawal under said Sections 4203, 4204 and 4205, (ix) to the best knowledge
of the Company and its subsidiaries, there are no material pending, threatened
or anticipated claims involving any of the Company Plans other than claims for

deficiency" (as defined in Section 302 of ERISA and Section 412 of the Code) or
is required to provide security to a Company Plan pursuant to Section 401(a)(29)

previously reflected in the financial statements (or notes thereto) included in
the Company SEC Reports.

subsidiaries, taken as a whole.

     (b) The Company agrees to pay to Parent a fee equal to $39,000,000 if:

         (i)  the Company terminates this Agreement pursuant to clause (iv) or
              (v) of Section 9.1(a); or

         (ii) Parent terminates this Agreement pursuant to clause (v) of Section
              9.1(b);

provided, however, that if the provisions of paragraph 5 of the Confidentiality
Agreement between Parent as Recipient and the Company as Protected Party have
lapsed and are no longer in force and effect as a result of the proviso set
forth in paragraph 5 of such Confidentiality Agreement and Parent has taken
actions that would otherwise be prohibited by paragraph 5 of such
Confidentiality Agreement prior to the time that Parent is entitled to receive
the payment required by this Section 7.6(b), Parent shall not be entitled to
receive such payment if such payment shall later become payable pursuant to the
terms of this Section 7.6(b); and, provided, further, that if Parent has
received the payment required by this Section 7.6(b), the proviso set forth in
paragraph 5 of such Confidentiality Agreement shall no longer be effective.

      (c)  Parent agrees to pay to the Company a fee equal to $39,000,000 if the
Company terminates this Agreement pursuant to clause (vi) of Section 9.1(a).

     SECTION 7.7.   AGREEMENT TO COOPERATE.  (a)  Subject to the terms and
conditions herein provided and subject to the fiduciary duties of the respective
boards of directors of the Company and Parent, each of the parties hereto shall
use all reasonable efforts to take, or cause to be taken, all action and to do,
or cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the transactions
contemplated by this Agreement, including using its reasonable efforts to obtain
all necessary or appropriate waivers, consents or approvals of third parties
required in order to preserve material contractual relationships of the Company
and its subsidiaries, all necessary or appropriate waivers, consents and
approvals and SEC "no-action" letters to effect all necessary registrations,
filings and submissions and to lift any injunction or other legal bar to the
Merger (and, in such case, to proceed with the Merger as expeditiously as
possible).

     (b) Without limitation of the foregoing, each of Parent and the Company
undertakes and agrees to file as soon as practicable after the date hereof a
Notification and Report Form under the HSR Act with the

                                    Page 32
<PAGE>
 
Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the  "Antitrust Division").  Each of Parent and the
Company shall (i) use its reasonable efforts to comply as expeditiously as
possible with all lawful requests of the FTC or the Antitrust Division for
additional information and documents and (ii) not extend any waiting period
under the HSR Act or enter into any agreement with the FTC or the Antitrust
Division not to consummate the transactions contemplated by this Agreement,
except with the prior written consent of the other parties hereto.

     (c)  In the event any litigation is commenced by any person or entity
relating to the transactions contemplated by this Agreement, including any
Acquisition Transaction, Parent shall have the right, at its own expense, to
participate therein, and the Company will not settle any such litigation without
the consent of Parent, which consent will not be unreasonably withheld.

     SECTION 7.8.   PUBLIC STATEMENTS.  The parties shall consult with each
other prior to issuing any press release or any written public statement with
respect to this Agreement or the transactions contemplated hereby and shall not
issue any such press release or written public statement prior to such
consultation.

     SECTION 7.9.   OPTION PLANS.  Prior to the Effective Time, the Company and
Parent shall take such action as may be necessary to cause each unexpired and
unexercised option to purchase shares of Company Common Stock (each a "Company
Option") to be automatically converted at the Effective Time into an option
(each a "Parent Option") to purchase a number of shares of Parent Common Stock
equal to the number of shares of Company Common Stock that could have been
purchased under the Company Option multiplied by the Exchange Ratio, at a price
per share of Parent Common Stock equal to the option exercise price determined
pursuant to the Company Option divided by the Exchange Ratio and subject to the
same terms and conditions as the Company Option.  The date of grant of a
substituted Parent Option shall be the date on which the corresponding Company
Option was granted.  At the Effective Time, all references in the stock option
agreements to the Company shall be deemed to refer to Parent.  Parent shall
assume all of the Company's obligations with respect to Company Options as so
amended and shall, from and after the Effective Time, make available for
issuance upon exercise of the Parent Options all shares of Parent Common Stock
covered thereby and amend its Registration Statement on Form S-8 or file a new
registration statement to cover the additional shares of Parent Common Stock
subject to Parent Options granted in replacement of Company Options.

     SECTION 7.10.  NOTIFICATION OF CERTAIN MATTERS.  Each of the Company,
Parent and Subsidiary agrees to give prompt notice to each other of, and to use
their respective reasonable best efforts to prevent or promptly remedy, (i) the
occurrence or failure to occur or the impending or threatened occurrence or
failure to occur, of any event which occurrence or failure to occur would be
likely to cause any of its representations or warranties in this Agreement to be
untrue or inaccurate in any material respect at any time from the date hereof to
the Effective Time and (ii) any material failure on its part to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder; provided, however, that the delivery of any notice pursuant to
this Section 7.10 shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

     SECTION 7.11.  DIRECTORS' AND OFFICERS' INDEMNIFICATION.  (a) The
indemnification provisions of the Certificate of Incorporation of the Surviving
Corporation as in effect at the Effective Time shall not be amended, repealed or
otherwise modified for a period of six years from the Effective Time in any
manner that would adversely affect the rights thereunder of individuals who at
the Effective Time were directors, officers, employees or agents of the Company,
unless such modification is required by law.

     (b) After the Effective Time, each of Parent and the Surviving Corporation
shall, to the fullest extent permitted under applicable law, indemnify and hold
harmless, each present and former director, officer, employee and agent of the
Company or any of its subsidiaries (each, together with such person's heirs,
executors or administrators, an  "indemnified Party" and collectively, the
"indemnified Parties") against any costs or expenses (including attorneys fees),
judgments, fines, losses, claims, damages, liabilities and amounts paid in
settlement in connection with any actual or threatened claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of, relating to or in connection with any action or
omission occurring prior to the Effective Time (including, without limitation,
acts or omissions in connection with such persons serving as an officer,
director or other fiduciary in any entity if such service was at the request or
for the benefit of the Company) or arising out of or pertaining to the
transactions contemplated by this Agreement.  In the event of any such  actual
or threatened claim, action, suit, proceeding or investigation (whether arising
before or after the Effective Time), (i) the Company or Parent and the Surviving
Corporation, as the case may be, shall pay the reasonable fees and expenses of
counsel selected by the indemnified Parties, which counsel shall be reasonably
satisfactory to the Parent and the Surviving Corporation, promptly after
statements therefor are received and shall pay all other reasonable expenses in
advance of the final disposition of such action, (ii) the Parent and the
Surviving Corporation will cooperate and use all reasonable efforts to assist in
the vigorous defense of any such matter, and (iii) to the extent any
determination is required to be made with respect to whether an indemnified
Party's conduct complies with the standards set forth under the DGCL and the
Parent's or the Surviving Corporation's respective charters or By-Laws such
determination shall be made by independent legal counsel acceptable to the
Parent or the Surviving Corporation, as the case may be, and the indemnified
Party; provided, however, that neither Parent nor the Surviving Corporation
shall be liable for any settlement effected without its written consent (which
consent shall not be unreasonably withheld) and, provided, further, that if
Parent or the Surviving Corporation advances or pays any amount to any person
under this paragraph (b) and if it shall thereafter be finally determined by a
court of competent jurisdiction that such person was not entitled to be
indemnified hereunder for all or any portion of such amount, such person shall
repay such amount or such portion thereof, as the case may be, to Parent or the
Surviving Corporation, as the case may be.  The indemnified Parties as a group
may not retain more than one law firm to represent them with respect to each
matter unless there is, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
indemnified Parties.

     (c) In the event the Surviving Corporation or Parent or any of their
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then and in each such case, proper
provisions shall be made so that the successors and assigns of the Surviving
Corporation or Parent shall assume the obligations set forth in this Section
7.11.

     (d) For a period of six years after the Effective Time, Parent shall cause
to be maintained in effect the current policies of directors' and officers'
liability insurance maintained by the Company and its subsidiaries (provided
that Parent may substitute therefor policies of at least the same coverage and
amounts containing terms and conditions that are no less advantageous in any
material respect to the indemnified

                                    Page 34
<PAGE>
 
Parties and which coverages and amounts shall be no less than the coverages and
amounts provided at that time for Parent's directors and officers) with respect
to matters rising before the Effective Time, provided that Parent shall not be
required to pay an annual premium for such insurance in excess of two times the
current annual premium paid by the Company for its existing coverage (the
"Cap"); and provided, further, that if equivalent coverage cannot be obtained,
or can be obtained only by paying an annual premium in excess of the Cap, Parent
shall only be required to obtain as much coverage as can be obtained by paying
an annual premium equal to the Cap.

     (e) Parent shall pay all reasonable expenses, including reasonable
attorneys' fees, that may be incurred by any indemnified Person in enforcing the
indemnity and other obligations provided in this Section 7.11.

     (f) The rights of each indemnified Party hereunder shall be in addition to
any other rights such indemnified Party may have under the charter or bylaws of
the Company, under the DGCL or otherwise. The provisions of this Section 7.11
shall survive the consummation of the Merger and expressly are intended to
benefit each of the indemnified Parties.

     SECTION 7.12.  CORRECTIONS TO THE JOINT PROXY STATEMENT/PROSPECTUS AND
REGISTRATION STATEMENT.   Prior to the date of approval of the Merger by their
respective stockholders, each of the Company, Parent and Subsidiary shall
correct promptly any information provided by it to be used specifically in the
Joint Proxy Statement/Prospectus and Registration Statement that shall have
become false or misleading in any material respect and shall take all steps
necessary to file with the SEC and have declared effective or cleared by the SEC
any amendment or supplement to the Joint Proxy Statement/Prospectus or the
Registration Statement so as to correct the same and to cause the Joint Proxy
Statement/Prospectus as so corrected to be disseminated to the stockholders of
the Company and Parent, in each case to the extent required by applicable law.

     SECTION 7.13.  EFFECT ON ACCOUNTING TREATMENT.  Each of the parties hereto
agrees that, notwithstanding anything to the contrary contained in the
Agreement, nothing contained in or contemplated by this Agreement shall require
any of the parties hereto to take any action which would jeopardize the
treatment of the Merger as a pooling of interests under APB No. 16.

     SECTION 7.14.  AMENDMENT OF CERTAIN ACQUISITION AGREEMENTS.  The Company
shall use its reasonable best efforts to amend the agreements listed on Schedule
5.2 of the Company Disclosure Schedule to eliminate the rights of the other
parties to such agreements to receive Company Common Stock, such amendments to
be on terms that are reasonably acceptable to Parent.

                      FIRST AMENDMENT TO RIGHTS AGREEMENT



          This Amendment, dated as of June 22, 1996 (the "Amendment"), is

          WHEREAS, the Company and First City Texas-Houston, N.A., as rights
agent, were parties to a Rights Agreement dated as of December 1, 1991 (the
"Agreement"); and

          WHEREAS, the Rights Agent is the successor rights agent to First City
Texas-Houston, N.A.; and

          WHEREAS, pursuant to Section 26 of the Agreement, the Company and the
Rights Agent desire to amend the Agreement set forth below.

          NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

          Section 1.  Amendments to Section 1.

          (a) The definition of "Beneficial Owner" is amended by adding the
following at the end of the definition:

     ; and provided, further, that so long as neither Parent, Subsidiary nor any
     of their Affiliates or Associates is not otherwise an Acquiring Person,
     then Parent, Subsidiary and their Affiliates and Associates shall not be
     deemed the "Beneficial Owner" of, or to "beneficially own," any security by
     having entered into the Merger Agreement or consummating the transactions
     contemplated therein. In interpreting the preceding proviso and other
     provisions of this Amendment, it is understood that (i) Parent and

     paragraph 5) shall not be deemed to be a transaction contemplated by the
     Merger Agreement.  No Director Stockholder shall be deemed to be the
     Beneficial Owner of nor to beneficially own any Common Shares that are

                                       1

purpose, together with payment of the aggregate Purchase Price (except as
provided in Section 11(q) hereof) with respect to the total number of Preferred
Share Fractions (or Common Shares, other securities, cash or other assets, as
the case may be) as to which such surrendered Rights are then exercisable

23 hereof, or (iv) the "Effective Time" as such term is defined in the Merger
Agreement (the earlier of (i), (ii), (iii) and (iv) being herein referred to as
the "Expiration Date").

     Section 3.  New Section 34.

     The following is added as a new Section 34:

          Section 34.  The Merger.  None of the execution or delivery of the
     Merger Agreement or the Stockholders Voting Agreements nor the consummation

terms, provisions, covenants and restrictions of this Amendment shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

CONTRACT MADE UNDER THE LAWS OF THE STATE OF DELAWARE AND FOR ALL PURPOSES SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SUCH STATE
APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE.

      Section 6. Counterparts.  This Amendment may be executed in any number of
counterparts and each of such counterparts shall for all purposes be deemed to
be an original, and all such counterparts shall together constitute but one and
the same instrument.

      Section 7. Effect of Amendment. Except as expressly modified herein, the
Agreement shall remain in full force and effect.

                                       3
