         1.3      EFFECTIVE TIME. Subject to the provisions of this Agreement,
as soon as practicable on or after the Closing Date, the parties shall (i)
file a certificate of merger with the Secretary of State of the State of
Delaware and (ii) make all other filings or recordings required by the DGCL in
connection with the Merger. The Merger shall become effective at such time as

State of Delaware or at such other time as is specified in the certificate of
merger (the "Effective Time").

         1.4      EFFECTS OF THE MERGER. The Merger shall have the effects set
forth in the DGCL. From and after the Effective Time, the Surviving
Corporation shall possess all the rights, privileges, powers and franchises
and be subject to all of the restrictions, disabilities and duties of Merger

the debts and liabilities of the Surviving Corporation, all as provided under
the DGCL.

         1.5      CERTIFICATE OF INCORPORATION. At the Effective Time, the
Certificate of Incorporation of Merger Sub, attached hereto as EXHIBIT A,
shall become the Certificate of Incorporation of the Surviving Corporation
until the same shall be altered or amended in accordance with applicable law.

         1.6      BYLAWS. At the Effective Time, the bylaws of Merger Sub,
attached hereto as EXHIBIT B, shall become the bylaws of the Surviving

         1.7      DIRECTORS AND OFFICERS OF THE SURVIVING CORPORATION. From
and after the Effective Time, until the earlier of their death, resignation or

         from the Effective Time and no consideration shall be paid with respect
         thereto.

                  (b)   CONVERSION OF COMMON STOCK. At the Effective Time, each

         "BDCO Common Stock"), other than Dissenting Shares (as defined in
         Section 1.10) that are owned by Dissenting Stockholders (as defined in
         Section 1.10) that have properly exercised appraisal rights pursuant to
         Section 262 of the DGCL and shares to be cancelled in accordance with
         Section 1.8(a). All such shares of Common Stock shall no longer be
         outstanding and shall automatically be cancelled and retired and shall
         cease to exist, and each holder of a certificate representing any such
         shares of Common Stock shall cease to have any rights with respect
         thereto, except the right to receive the Merger Consideration (as
         defined in Section 1.9(a)) upon surrender of such certificate in

         each issued and outstanding share of ARO's Series 1993 Preferred Stock,
         par value $12.00 per share (the "Preferred Stock"), shall be converted
         into the right to receive .0301 of a share of BDCO Common Stock, other
         than Dissenting Shares (as defined in Section 1.10) that are owned by
         Dissenting Stockholders (as defined in Section 1.10) that have properly
         exercised appraisal rights pursuant to Section 262 of the DGCL and
         shares to be cancelled in accordance with Section 1.8(a). All such
         shares of Preferred Stock shall no longer be outstanding and shall
         automatically be cancelled and retired and shall cease to exist, and
         each holder of a certificate representing any such shares of Preferred
         Stock shall cease to have any rights with respect thereto, except the
         right to receive the Merger Consideration upon surrender of such
         certificate in accordance with Section 1.9.

                  (d)   CONVERSION OF MERGER SUB COMMON STOCK. At the Effective
         Time, each issued and outstanding share of common stock, par value $.01
         per share, of Merger Sub shall be converted into one share of common
         stock, par value $.01 per share, of the Surviving Corporation
         ("Surviving Corporation Common Stock").

                  (e)   STOCK RIGHTS. ARO agrees that prior to the Effective
         Time it will cause any and all options, warrants, convertible
         securities (or other securities or rights issued by ARO, which entitle
         the holder to acquire Common Stock, Preferred Stock, other securities
         or assets from ARO), other than the Preferred Stock, to be (i) canceled
         without cost to ARO, or (ii) exercised or converted into Common Stock.

         1.9      SURRENDER AND PAYMENT OF CERTIFICATES.

                  (a)   EXCHANGE AGENT. Prior to the Effective Time, BDCO shall
         appoint Securities Transfer Corporation (or such other person or entity
         as BDCO may designate) to act as Exchange Agent (the "Exchange Agent").
         At or prior to the Effective Time, BDCO shall deposit with the Exchange
         Agent certificates representing shares of BDCO Common Stock and cash in
         lieu of fractional shares, if any, as provided below, (the

                                       3

<Page>

         BDCO Common Stock together with any cash necessary to make payments
         in lieu of fractional shares, the "Merger Consideration") to be
         issued in exchange for the issued and outstanding shares of Common
         Stock and Preferred Stock. Promptly after the Effective Time, the
         Exchange Agent will send, to each holder of record, as of the
         Effective Time, of a certificate or certificates which at the
         Effective Time represented shares of Common Stock and Preferred Stock
         (the "Certificates") (i) a letter of transmittal (which shall specify
         that the delivery shall be effected, and risk of loss and title shall
         pass, only upon proper delivery of the Certificates to the Exchange
         Agent and which shall be in customary form and have such provisions
         as BDCO may reasonably specify) and (ii) instructions for use in
         surrendering the Certificates in exchange for the Merger
         Consideration.

                  (b)   Upon surrender of a Certificate for cancellation to the
         Exchange Agent, together with a duly completed and validly executed
         letter of transmittal and such other documents as the Exchange Agent
         and BDCO shall reasonably require, the holder of such Certificates will
         be entitled to receive the Merger Consideration payable in respect of
         each such Certificate. Until so surrendered, each such Certificate
         shall, after the Effective Time, represent for all purposes, only the
         right to receive the Merger Consideration.

                  (c)   If any portion of the Merger Consideration is to be paid
         to a Person (as defined in Section 7.3) other than the registered
         holder of the Common Stock or Preferred Stock represented by the
         Certificates surrendered in exchange therefor, it shall be a condition
         to such payment that the Certificates so surrendered shall be properly
         endorsed or otherwise be in proper form for transfer and that the
         Person requesting such payment shall pay to the Exchange Agent any
         transfer or other taxes required as a result of such payment to a
         Person other than the registered holder of such Certificates or
         establish to the satisfaction of the Exchange Agent that such tax has
         been paid or is not payable.

                  (d)   TERMINATION OF PAYMENT FUND. Any portion of the Merger
         Consideration made available to the Exchange Agent pursuant to Section
         1.9(a) that remains unclaimed by holders of Common Stock and Preferred
         Stock six months after the Effective Time shall be promptly returned to
         the Surviving Corporation, upon demand, and any such holder who has not
         exchanged his Certificates for the Merger Consideration in accordance
         with this Section prior to that time shall thereafter look only to the
         Surviving Corporation for payment of their claim for the Merger
         Consideration.

                  (e)   NO LIABILITY. Notwithstanding the foregoing, the
         Surviving Corporation shall not be liable to any holder of Common
         Stock or Preferred Stock for any amount paid to a public official
         pursuant to any applicable abandoned property law. Any amounts
         remaining unclaimed by holders of Common Stock or Preferred Stock two
         years after the Effective Time (or such earlier date immediately
         prior to such time as such amounts would otherwise escheat to or
         become property of any governmental entity) shall, to the extent
         permitted by applicable law, become the property of the Surviving
         Corporation free and clear of any claims or interest of any Person
         previously entitled thereto.

                                       4

         1.10     DISSENTERS' RIGHTS. Notwithstanding anything in this
Agreement to the contrary, any shares of Common Stock or Preferred Stock
outstanding immediately prior to the Effective Time and held by a holder who
has not voted in favor of the Merger or consented thereto in writing (a
"Dissenting Stockholder") and who has timely delivered a written demand for
appraisal of such shares in accordance with Section 262 of the DGCL
("Dissenting Shares"), if any, shall not be converted into the right to
receive the Merger Consideration, unless and until such holder fails to
perfect or effectively withdraws or otherwise loses his right to appraisal and
payment under the DGCL. If any person who otherwise would be deemed a
Dissenting Stockholder shall have failed to properly perfect or shall have
effectively withdrawn or lost the right to dissent with respect to any Common
Stock or Preferred Stock, such shares of Common Stock or Preferred Stock shall
thereupon be treated as though such shares had been converted into the right
to receive the Merger Consideration with respect to such Common Stock and
Preferred Stock as provided in this Article 1. ARO shall give BDCO (i) prompt
notice of any written demands for appraisal, attempted withdrawals of such
demands and any other instruments served pursuant to applicable law received
by ARO relating to stockholders' rights of appraisal and (ii) the opportunity
to participate in all negotiations and proceedings with respect to demand for
appraisal under the DGCL. ARO shall not, except with the prior written consent
of BDCO, voluntarily make any payment with respect to any demands for
appraisals of Dissenting Shares, offer to settle or settle any such demands or
approve any withdrawal of any such demands.

         1.11     STOCK TRANSFER BOOKS. After the Effective Time, there shall
be no further registration of transfers of shares of the Common Stock or
Preferred Stock on the stock transfer books of the Surviving Corporation. If,
after the Effective Time, certificates representing shares of Common Stock or
Preferred Stock are presented to the Surviving Corporation or the Exchange
Agent, they shall be canceled and exchanged for the Merger Consideration
provided for, and in accordance with the procedures set forth, in this Article
1.

         1.12     FRACTIONAL SHARES. No certificates representing fractional
shares of BDCO Common Stock shall be issued to holders of Common Stock or
Preferred Stock upon the surrender for exchange of Certificates, and such
holders shall not be entitled to any voting rights, rights to receive any
dividends or distributions or other rights as a stockholder of BDCO with
respect to any fractional shares of BDCO Common Stock that would otherwise be
issued to such holders. In lieu of any fractional shares of BDCO Common Stock
that would otherwise be issued, each holder of Common Stock or Preferred Stock
that would have been entitled to receive a fractional share of BDCO Common
Stock shall, upon proper surrender of such holder's Certificates, receive a
cash payment (rounded to the nearest cent), without interest, equal to the
average closing price per share of BDCO Common Stock as reported in the
consolidated transaction reporting system on the five trading days immediately
preceding the Effective Time, multiplied by the fraction of a share that such
holder would otherwise be entitled to receive (rounded to the nearest
hundredth of a share).

         1.13     FURTHER ASSURANCES. Each party hereto agrees that it will
take appropriate action so that if, at any time after the Effective Time, any
further action is necessary or desirable to carry out the purposes of this
Agreement, the persons who are officers and directors of the Surviving

                                       5

Corporation are fully authorized in the name of Merger Sub and ARO to take,
and shall take, all such lawful and necessary action.

                         REPRESENTATIONS, WARRANTIES AND
                                AGREEMENTS OF ARO

qualified or licensed to do business in, and is, or at the Effective Time will
be, in good standing as a foreign corporation authorized to do business in,
all jurisdictions in which the character of the properties owned or the nature
of the business conducted would make such qualification or licensing
necessary, except in those jurisdictions where the failure to be so qualified
or licensed and in good standing does not and will not, individually or in the
aggregate, have a Material Adverse Effect on ARO.

         2.2      AUTHORIZATION; VALIDITY OF AGREEMENT; COMPANY ACTION. The
execution and delivery of this Agreement by ARO has been duly authorized by
the Board of Directors of ARO, and consummation of the transactions

a majority of the combined voting power the Common Stock and Preferred Stock
voting together as a class and (ii) the holders of a majority of the Preferred
Stock voting separately as a class. This Agreement is a valid and binding
obligation of ARO, enforceable against it in accordance with its terms, except

moratorium, or similar laws affecting the rights of creditors generally and
general principles of equity.

         2.3      CAPITALIZATION.

                  (a)   The authorized capital stock of ARO consists of (i)

         been, and all shares which may be issued pursuant to exercise of
         outstanding options or conversion of Preferred Stock will be, when

                  (b)   There are no outstanding subscriptions, options, notes,
         bonds, debentures, convertible securities, warrants, rights or calls of
         any kind issued or granted by or binding upon ARO which entitle any
         person to purchase or otherwise acquire any security of, or equity
         interest in, ARO other than the Preferred Stock and options to
         acquire 100,000 shares of Common Stock. There are no outstanding
         rights or agreements of any kind obligating ARO to repurchase or
         redeem any securities of ARO or any other Person. No shares of ARO
         capital stock are held as treasury shares. To the knowledge of ARO,
         none of ARO's outstanding Common Stock is subject to any right of
         first refusal, voting trust, voting agreement, or other agreement or
         understanding with respect to the voting thereof, nor is any proxy in
         existence with respect thereto, other than proxies solicited by the
         Board of Directors of ARO in connection with the ARO Stockholders'
         Meeting (as defined in Section 4.5).

         no outstanding subscriptions, options, convertible securities,
         warrants, rights or calls of any kind issued or granted by ARO, or
         binding upon the Surviving Corporation, which would entitle the
         holder thereof upon exercise or conversion to acquire Common Stock,
         Preferred Stock, or any other equity security or debt security of ARO
         or to receive any of the Merger Consideration; and (ii) any
         outstanding subscriptions, options, warrants, rights or calls to

         Time shall be canceled whether or not then vested, or exercisable or
         convertible.

         during the periods involved (except as may be indicated in the notes
         thereto and subject, in the case of quarterly financial statements, to
         normal and recurring year-end adjustments) and fairly present the
         consolidated financial position and the consolidated results of
         operations and cash flows (and changes in financial position, if any)
         of ARO at the dates thereof or for the periods presented therein.

                  (b)   There is no event or condition which would render ARO

information to be supplied by or on behalf of BDCO and Merger Sub for
inclusion in the Proxy Statement (including any information incorporated by
reference in the Registration Statement from other filings made by BDCO with
the SEC) shall not on the date the Proxy Statement is first mailed to
stockholders or at the time of the ARO Stockholders' Meeting, contain any
untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statement
therein, in light of the circumstances under which they are made, not false or
misleading. Other than with respect to the information supplied by or on
behalf of ARO, the Registration Statement shall not at the time the
Registration Statement becomes effective under the Securities Act contain any
untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein not misleading in light of
the circumstances under which they were made. The Registration Statement will
comply (other than with respect to information relating to ARO) as to form in
all material respects with the provisions of the Securities Act and the rules
and regulations thereunder.

         3.5      SEC REPORTS AND FINANCIAL STATEMENTS. As of their respective
dates or, if amended, as of the date of the last such amendment, all reports
and other documents required to be filed by BDCO under the Exchange Act since
January 1, 2001 (as such documents have been amended since the time of their
filing, collectively, the "BDCO SEC Documents"), including, without
limitation, any financial statements or schedules included therein (i) did not
contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading and (ii) complied in all material respects with the applicable
requirements of the Exchange Act, as the case may be, and the applicable rules
and regulations thereunder. The financial statements (and the related notes
thereto collectively the "BDCO Financial Statements") included in BDCO's
Annual Report on Form 10-K for the fiscal year ended December 31, 2000, as
amended, (the "BDCO 2000 Form 10-K") and the quarterly reports on Form 10-Q
for the periods ended March 31, 2001 and June 30, 2001 (collectively, the
"BDCO Form 10-Qs"), have been prepared in accordance with GAAP applied on a
consist basis during the periods involved (except as may be indicated in the
notes thereto and subject, in the case of quarterly financial statements, to
normal and recurring year-end adjustments) and fairly present the consolidated
financial position and the consolidated results of operations and cash flows
(and changes in financial position, if any) of BDCO as of the dates thereof or
for the periods presented therein.

         3.6      NO VIOLATION OF AGREEMENTS OR GOVERNING DOCUMENTS. Neither
the execution and delivery of this Agreement by each of BDCO and Merger Sub
nor consummation of the Merger or the other transactions contemplated hereby
will (a) conflict with the certificate of incorporation or the bylaws of BDCO,
or the certificate of incorporation or the bylaws of Merger Sub, (b) result in
any breach or termination of, or constitute an event which with notice or
lapse of time, or both, would become a default under, or result in the
creation of any Encumbrance upon any asset of BDCO, or create any rights of
termination, cancellation, modification, amendment, or acceleration in any
Person under any agreement, lease, insurance policy, arrangement or
commitment, (c) violate any order, writ, injunction or decree, to which BDCO
is a party or by which any of its assets, businesses or operations may be
bound or affected, or under which BDCO

                                      11

or any of its assets, businesses or operations receive benefits, (d) except as
set forth in SECTION 3.6 of the BDCO Disclosure Letter, require the consent,
approval, authorization, or order of any person or Governmental Authority, or
court under any agreement, arrangement, commitment, order, writ, injunction,
or decree not heretofore obtained other than those consents or approvals
specifically contemplated hereby, or except as set forth in SECTION 3.6 of the
BDCO Disclosure Letter, result in the loss or modification or any license,
franchise, permit or other authorization granted to or otherwise held by BDCO.
BDCO agrees that it will use its best efforts to obtain any consents necessary
to be obtained by BDCO prior to the Effective Time.

         3.7      LITIGATION. Except as would not, individually or in the
aggregate, have a Material Adverse Effect on the Company or as described in

arbitration, or other proceeding or governmental investigation pending or
threatened to which BDCO is a party and none is threatened.

There is no action, suit or proceeding pending or threatened against or
specially affecting BDCO at law or in equity, or before any Governmental
Authority.

         3.9      UNDISCLOSED LIABILITIES. Neither BDCO nor any of its
Subsidiaries has any liabilities or obligations of any nature, whether or not
fixed, accrued, contingent or otherwise, except liabilities and obligations
that (i) are disclosed in the BDCO SEC Documents or (ii) do not and are not
reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on BDCO.

         3.10     BROKERS. No broker, investment banker, financial advisor or
other person is entitled to any broker's, finder's, financial advisor's or

the exhibits and appendices hereto, the financial statements and all other
documents and information furnished by BDCO or any of its respective
Affiliates or representatives to ARO or their representatives pursuant hereto
or in connection herewith does not include and will not include any untrue
statement of a material fact or omit to state any material fact necessary to
make the statements made herein and therein not misleading. There are no facts
which materially and adversely affect or, so far as BDCO can now reasonably
foresee, will materially and adversely affect the business, prospects,
operations or principal properties of BDCO or the ability of any party to
perform its obligations under this Agreement.

         4.4      ADDITIONAL AGREEMENTS REGARDING REGISTRATION STATEMENT,
PROXY STATEMENT/PROSPECTUS.

                  (a)   As promptly as practicable after the execution of this
         Agreement, ARO and BDCO will jointly prepare and file with the SEC a
         preliminary proxy statement (with appropriate requests for confidential
         treatment) relating to the Merger and this Agreement (such proxy
         statement, as amended or supplemented, the "Proxy Statement"), and BDCO
         will prepare and file with the SEC a registration statement on Form S-4
         (as amended or supplemented, the "Registration Statement"), in which
         the Proxy Statement shall be included as a part of the prospectus. BDCO
         will use commercially reasonable efforts to cause the Registration
         Statement to be declared effective under the Securities Act as soon as
         practicable after such filing, and will take all actions required under
         applicable federal or state securities laws in connection with the
         issuance of the BDCO Common Stock in the Merger. Each party will notify
         the other promptly upon the receipt of any comments from the SEC or its
         staff and of any request by the SEC or its staff or any other
         government officials for amendments or supplements to the Proxy
         Statement, the Registration Statement and any other filing or for
         additional information and will supply the other party with copies of
         all correspondence between such party or any of its representatives, on
         the one hand, and the SEC, or its staff or any other government
         officials, on the other hand, with respect to the Registration
         Statement, the Proxy Statement or the Merger. Whenever any event occurs
         that is required to be set forth in an amendment or supplement to the
         Registration Statement or the Proxy Statement, the relevant party will
         promptly inform the other party of such occurrence and cooperate in
         filing with the SEC or its staff or any other government officials,
         and/or mailing to stockholders of ARO, such amendment or supplement.

                  (b)   The Proxy Statement will include the recommendation of
         the Special Committee in favor of approval of this Agreement (except
         that the Special Committee may withdraw, modify or refrain from
         making such recommendation to the extent that the Special Committee
         determines after consultation with outside legal counsel that failure
         to do so would violate the Special Committee's fiduciary duties under
         applicable law).

                                      14

<Page>

                  (c)   The Proxy Statement will include the recommendation of
         the Board of Directors of ARO in favor of approval of this Agreement
         (except that the Board of Directors of ARO may withdraw, modify or
         refrain from making such recommendation to the extent that the Board
         determines after consultation with outside legal counsel that failure
         to do so would violate the Board's fiduciary duties under applicable
         law).

                  (d)   ARO agrees that the Proxy Statement: (i) will be
         prepared and circulated pursuant to and in compliance with Section
         14(a) of the Exchange Act, Regulation 14A promulgated under the
         Exchange Act, and all other applicable federal and state securities
         laws and regulations; (ii) will contain all notices and disclosures
         to stockholders required by the DGCL with respect to this Agreement,
         the Merger and the other transactions contemplated hereby, and (iii)
         will not contain any statement which, at the time and in the light of
         the circumstances under which it is made, is false or misleading with
         respect to any material fact, or which omits to state any material
         fact necessary in order to make the statements therein not false or
         misleading or necessary to correct any statement in any earlier
         communication with respect to the solicitation of a proxy for the
         same meeting or subject matter which has become false or misleading.

         4.5      MEETING OF THE ARO STOCKHOLDERS. Promptly after the date
hereof, ARO will, in accordance with the DGCL and its certificate of
incorporation and bylaws, use its reasonable best efforts to convene a
stockholders' meeting (the "ARO Stockholders' Meeting") to be held as promptly
as practicable for the purpose of voting upon this Agreement and the Merger.
Unless the Special Committee determines, after consultation with outside legal
counsel, that to do so would be inconsistent with the Board's or the Special
Committee's fiduciary duties under applicable law, ARO will use its reasonable
best efforts to solicit from its stockholders proxies in favor of the approval
of this Agreement and the Merger and to take all other reasonable action
necessary or advisable to secure the vote or consent of its stockholders
required by the DGCL to obtain such approvals. BDEX shall vote or cause to be
voted, all of the Common Stock then owned by it and any of its subsidiaries in
favor of the approval of this Agreement and the Merger.

         4.6      PUBLIC DISCLOSURE. BDCO and ARO will consult with each other
before issuing any press release or otherwise making any public statement with
respect to the Merger or this Agreement and will not issue any such press
release or make any such public statement prior to such consultation, except
as may be required by applicable law or any rules or regulations of any
securities exchange or automated quotation system of a national securities
association. Promptly upon the execution hereof, the parties shall jointly
make a press release with respect to the transactions contemplated by this
Agreement, in form reasonably satisfactory to the Special Committee.

         4.7      NASDAQ SMALL CAP MARKET LISTING. BDCO shall use its best
efforts to cause all shares of BDCO Common Stock issuable to holders of Common
Stock and Preferred Stock as a result of the Merger to be authorized for
listing on the NASDAQ Small Cap Market or such securities exchange or
automated quotation system of a national securities association on which the
BDCO Common stock is then listed or upon which the BDCO Common Stock will
become listed upon the Closing.

         4.8      INDEMNIFICATION.

                  (a)   BDCO shall indemnify each current director and officer
         of the Company and its subsidiaries (the "Indemnified Parties") who was
         or is a party or is threatened to be a party to any action, suit or
         proceeding by reason of the fact that such person is or was a director
         or officer of ARO or its subsidiaries to the fullest extent permitted
         by Delaware law.

                  (b)   BDCO agrees that all rights to indemnification and
         advancement of expenses now existing in favor of any Indemnified Party
         and any other person who was a director or officer of ARO and its
         subsidiaries as provided in their respective charters or by-laws shall
         survive the Merger and shall continue in full force and effect for a
         period of not less than the longer of six years from the Effective Time
         and any applicable statute of limitations. After the Effective Time,
         BDCO agrees to cause the Surviving Corporation to honor all rights to
         indemnification and advancement of expenses referred to in the
         preceding sentence.

                  (c)   BDCO agrees that the Surviving Corporation shall cause
         to be maintained in effect for not less than six years (except as
         provided in the last sentence of this Section 4.8(c)) from the
         Effective Time the current policies of the directors' and officers'
         liability insurance maintained by ARO; provided that the surviving
         corporation may substitute therefor other not less advantageous (other
         than to a de minimis extent) to the beneficiaries of the current
         policies and provided that such substitution shall not result in any
         gaps or lapses in coverage with respect to matters occurring prior to
         the Effective Time.

                  (d)   From and after the Effective Time, any Indemnified Party
         wishing to claim indemnification under paragraphs (a) or (b) of this
         Section 4.8, upon learning of any such claim, action, suit, proceeding
         or investigation, shall promptly notify BDCO thereof. In the event of
         any such claim, action, suit, proceeding or investigation (whether
         arising before or after the Effective Time), (i) BDCO or the Surviving
         Corporation shall have the right, from and after the Effective Time, to
         assume the defense thereof and BDCO shall not be liable to such
         Indemnified Parties for any legal expenses of other counsel or any
         other expenses subsequently incurred by such Indemnified Parties in
         connection with the defense thereof, (ii) the Indemnified Parties will
         cooperate in the defense of any such matter, and (iii) BDCO shall not
         be liable for any settlement effected without its prior written
         consent, provided that BDCO shall not have any obligation hereunder to
         any Indemnified Party when and if a court of competent jurisdiction
         shall ultimately determine, and such determination shall have become
         final, that such person is not entitled to indemnification under
         applicable law.

                  terminate this Agreement pursuant to this Section 6.1(b)(i)
                  shall not be available to any party whose failure to perform
                  any of its obligations under this Agreement results in the
                  failure of the Merger to be consummated by such time; or

                      (ii) if stockholder approval shall not have been
                  obtained at the ARO Stockholders' Meeting duly convened
                  therefor or at any adjournment or postponement thereof.

                  (c) By BDCO, if ARO shall have breached or failed to perform
         in any material respect any of its representations, warranties,
         covenants or other agreements contained in this Agreement, which breach
         or failure to perform would give rise to a material adverse change
         relating to ARO and (A) is not cured within 30 days after written
         notice thereof or (B) is incapable of being cured by ARO; or

                  (d) By ARO, if BDCO shall have breached or failed to perform
         in any material respect any of its representations, warranties,
         covenants or other agreements contained in this Agreement, and such
         breach or failure to perform (A) is not cured within 30 days after
         written notice thereof or (B) is incapable of being cured by BDCO.

         6.2      EFFECT OF TERMINATION. In the event of the termination and
abandonment of this Agreement pursuant to and in accordance with the provisions
of Section 6.1(a), hereof, this Agreement shall become void and have no effect,
without any liability on the part of any party hereto (or its stockholders or
controlling persons or directors or officers).

party may (a) extend the time for the performance of any of the obligations or

or in any document delivered pursuant to this Agreement or (c) waive compliance
by the other party with any of the agreements or conditions contained in this
Agreement. Any agreement on the part of a party to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on behalf
of such party. The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a wavier of such
rights.

         6.5      PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR WAIVER. A
termination of this Agreement pursuant to Section 6.1 shall, in order to be
effective, require, in the case of BDCO or ARO, action by its Board of
Directors or, with respect to any amendment to this Agreement, the duly
authorized committee of its Board of Directors to the extent permitted by law.

        7.3       INTERPRETATION. When a reference is made in this Agreement to
an Article, Section or Exhibit, such reference shall be to an Article or
Section of, or an Exhibit to, this Agreement unless otherwise indicated. The
table of contents and headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement. Whenever the words "include," "includes" or "including" are
used in this Agreement, they shall be deemed to be followed by the words
"without limitation." The words "hereof", "herein" and "hereunder" and words of
similar import when used in this Agreement shall refer to this Agreement as a
whole and not to any particular provision of this Agreement. All terms defined
in this Agreement shall have the defined meanings when used in any certificate
or other document made or delivered pursuant hereto unless otherwise defined
therein. The definitions contained in this Agreement are applicable to the
singular as well as the plural forms of such terms and to the masculine as well
as to the feminine and neuter genders of such term. Any agreement, instrument
or statute defined or referred to herein or in any agreement or instrument that
is referred to herein means such agreement, instrument or statute as from time
to time amended, modified or supplemented, including (in the case of agreements
or instruments) by waiver or consent and (in the case of statutes) by
succession of comparable successor statutes and references to all attachments
thereto and instruments incorporated therein. For purposes of this Agreement,
(i) "Person" means an individual, corporation, partnership, limited liability
company, joint venture, association, trust, unincorporated organization or
other entity, (including its permitted successors and assigns) and (ii) an
"Affiliate" of any person means another person that directly or indirectly,
through one or more intermediaries, controls, is controlled by, or is under
common control with, such first person, where "control" means the possession,
directly or indirectly, of the power to direct or cause the direction of the
management policies of a person, whether through the ownership of voting
securities, by contract or otherwise.

        7.4       TIME OF ESSENCE. Time is of the essence in the performance of
this Agreement.

        7.5       HEADINGS AND CAPTIONS. The headings and captions contained in
this Agreement are solely for convenient reference and shall not be deemed to
affect the meaning or interpretation of any Article, Section, or paragraph
hereof, of this Agreement.

         7.6      ENTIRE AGREEMENT. This Agreement (including the schedules and
appendices hereto, all of which are by this reference fully incorporated into
this Agreement for all purposes) sets forth the entire agreement and
understanding of the parties with respect to the transactions


                                       21
<Page>


contemplated hereby, and supersedes all prior agreements, arrangements, and
understandings relating to the subject matter hereof.

        7.7       SUCCESSORS AND ASSIGNS. All of the terms, provisions,
covenants, representations, warranties, and conditions of this Agreement shall
be binding upon and shall inure to the benefit of and be enforceable by the
parties hereto and their respective heirs, legal representatives, and
successors, but this Agreement and the rights and obligations hereunder shall
not be assignable or delegable by any party.

        7.8       GENDER, AND CERTAIN REFERENCES. Whenever from the context it
appears appropriate, each term stated in either the singular or the plural
shall include both the singular and the plural, and pronouns stated in the
masculine or the neutral gender shall include the masculine, the feminine and
the neutral gender. The terms "hereof," "herein," "herewith," or "hereunder"
refer to this Agreement as a whole and not to any particular Article, Section,
or paragraph hereof. The term "include" and derivatives thereof are used in an
illustrative sense and not in a limiting sense. The term "or" is not exclusive.

        7.9       APPLICABLE LAW AND VENUE. All questions concerning the
construction, validity and interpretation of this Agreement shall be governed
by the internal laws, and not the law of conflicts, of the State of Delaware.
Except where arbitration is expressly provided for in this agreement, all
controversies which may arise out of or in connection with this agreement,
particularly with respect to the performance, interpretation, breach, or
enforcement of this agreement, shall be brought and resolved solely and
exclusively in the state or federal courts of Texas, and each party hereto
consents to service, jurisdiction, and venue of such courts for such purpose,
and each hereby irrevocably waives any other venue to which it might be
entitled by virtue of domicile, residence, jurisdiction of formation or
otherwise. Each party hereto acknowledges and agrees that it has consulted
legal counsel in connection with the negotiation of this Agreement and that it
has bargaining power equal to that of the other parties hereto in connection
with the negotiation and execution of this Agreement. Accordingly, the rule of
contract construction that an agreement shall be interpreted and construed
against the draftsman shall have no application in the interpretation or
construction of this Agreement.

        7.10      SEVERABILITY. If any term, provision, covenant, or
restriction of this Agreement is held by a court of competent jurisdiction to
be invalid, void, or unenforceable, the remainder of the terms, provisions,
covenants and restrictions shall remain in full force and effect and shall in
no way be affected, impaired or invalidated. It is hereby stipulated and
declared to be the intention of the parties that they would have executed this
Agreement had the terms, provisions, covenants and restrictions which may be
hereafter declared invalid, void, or unenforceable not initially been included
herein.

        7.11      RIGHTS OF PARTIES. Nothing in this Agreement, whether express
or implied, is intended to confer any rights or remedies under or by reason of
this Agreement on any persons other than the parties to it and their respective
successors and assigns, nor shall any provision give any third persons any
right of subrogation or action over or against any party to this Agreement.

Without limiting the generality of the foregoing, it is expressly understood
that this Agreement does not create any third party beneficiary rights.
