                          FORM OF INDEMNITY AGREEMENT


     This Indemnity Agreement is made this     day of        by and between 
Atlantic Richfield Company, a Delaware corporation ("ARCO"), and ("Indemnitee").


                                    RECITALS

     Section 25 of ARCO's By-Laws provides that ARCO  shall indemnify the
Indemnitee to the fullest extent authorized by the General Corporation Law of
Delaware, as the same exists or may hereafter be amended. The By-Laws (Section
25(e)) also provide that ARCO may from time to time enter into indemnity
agreements with the persons who are members of its Board of Directors and with
such officers and other persons as the Board may designate, such indemnity
agreements to provide in substance that ARCO will indemnify such person to the
fullest extent of the provisions of the By-Laws. The General Corporation Law of
Delaware (Section 145(f)) also provides that the indemnification authorized by
that Law shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled by law,
agreement or otherwise and ARCO's By-Laws (Section 25(c)) likewise provide that
the right to indemnification and the payment of expenses confirmed by the By-Law
shall not be exclusive of any other right which any person may have or hereafter
acquire under any agreement or otherwise.

     In exercising its discretion to authorize this Agreement, the Board of
Directors has considered the following, among other factors:

          (a) It is essential to ARCO to attract and retain as directors and
officers the most capable persons available.

          (b) The substantial increase in corporate litigation that may subject
directors and officers to litigation costs and risks and the recent limitations
on the availability of directors' and officers' liability insurance have made
and will make it increasingly difficult for ARCO to attract and retain such
persons.

          (c) When obtainable, insurance policies relating to indemnification
are often subject to retentions by the insured, co-insurance requirements,
exclusions and other limitations on coverage.

     In view of the foregoing and in recognition of the Indemnitee's need for
substantial protection against personal liability in order to assure the
Indemnitee's continued service to ARCO in an effective manner and the
Indemnitee's reliance on the provisions of ARCO's By-Laws, and in part to
provide the Indemnitee with specific contractual assurance that the protection
promised by the By-Laws will be available to the Indemnitee (regardless of,
among other things, any amendment to or revocation of such By-Laws or any change
in the composition of ARCO's Board of Directors or any acquisition transaction
relating to ARCO). ARCO wishes to provide in this Agreement for the
indemnification of and the advancing of expenses to the Indemnitee to the
fullest extent (whether partial or complete) permitted by law and as set forth
in this Agreement, and, to the extent insurance is maintained, for the continued
coverage of the Indemnitee under ARCO's directors' and officers' liability
insurance policies.

       In consideration of Indemnitee's continued service to ARCO, ARCO hereby 
agrees with the Indemnitee as follows:

       Section 1. DEFINITIONS.

       a.  Change in Control: shall be deemed to have occurred if (i) any 
"person" (as defined in Sections 3(a)(9) and 13(d)(3) of the Securities 
Exchange Act of 1934, as amended) is or becomes the beneficial owner, directly 
or indirectly, of securities of ARCO representing 25% or more of the total 
voting power represented by ARCO's then outstanding Voting Securities, or (ii) 
there shall occur a change in the composition of a majority of the Board of 
Directors of ARCO within a three-year period which change shall not have been 
approved by a majority of the persons then surviving as Directors who also 
comprised the Board of Directors of ARCO immediately prior to the commencement 
of such period, or (iii) the stockholders of ARCO approve a merger or 
consolidation of ARCO with any other corporation, other than a merger or 
consolidation which would result in the Voting Securities of ARCO outstanding 
immediately prior thereto continuing to represent (either by remaining 
outstanding or by being converted into Voting Securities of the surviving 
entity) at least 80% of the total voting power represented by the Voting 
Securities of ARCO or such surviving entity outstanding immediately after such 
merger or consolidation, or (iv) the stockholders of ARCO approve a plan of 
complete liquidation of ARCO or an agreement for the sale or disposition by 
ARCO (in one transaction or a series of transactions) of all or substantially 
all of ARCO's assets.

       b.  Claim: any threatened, pending or completed action, suit or 
proceeding, or any inquiry or investigation that the Indemnitee in good faith 
believes might lead to the institution of any such action, suit or proceeding, 
whether civil, criminal, administrative, investigative or other.

       c.  Potential Change in Control: shall be deemed to have occurred if (i) 
ARCO enters into an agreement or arrangement, the consummation of which would 
result in the occurrence of a Change in Control; (ii) any person (including 
ARCO) publicly announces an intention to take or to consider taking actions 
which if consummated would constitute a Change in Control; (iii) any person, 
other than a trustee or other fiduciary, holding securities under an employee 
benefit plan of ARCO acting in such capacity, or a corporation owned, directly 
or indirectly, by the stockholders of ARCO in substantially the same 
proportions as their ownership of stock of ARCO, who is or becomes the 
beneficial owner, directly or indirectly, of securities of ARCO representing 
10% or more of the combined voting power of ARCO's then outstanding Voting 
Securities, increases such person's beneficial ownership of such securities by 
5% or more over the percentage so owned by such person on the date hereof; or 
(iv) the Board of Directors adopts a resolution to the effect that, for 
purposes of this Agreement, a Potential Change in Control has occurred.

       d.  Reviewing Party: the Senior Vice President and General Counsel or 
any appropriate person or body selected by ARCO's Board of Directors who is not 
a party to the particular Claim for which the Indemnitee is seeking 
indemnification, and, if there has been a Change in Control (other than a 
Change in Control which has been approved by a majority of persons then 
surviving as Directors who comprised ARCO's Board of Directors immediately 
prior to such Change in Control), the Reviewing Party shall be the special 
independent counsel referred to in Section 5 of this Agreement.

       e.  Voting Securities: any securities of ARCO having the right under 
ordinary circumstances to vote at an election of the Board of Directors.

    Section 2. GENERAL RIGHT TO INDEMNIFICATION. Subject to Sections 3 and 4d,
ARCO shall indemnify the Indemnitee in the event that Indemnitee was or is a 
party or is threatened to be made a party to or is involved or is threatened to 
be involved (as a witness or otherwise) in or otherwise required representation 
by counsel in connection with any Claim, by reason of the fact that Indemnitee 
is or was a director or officer of ARCO or is or was serving at the request of 
ARCO as a director, officer, employee or agent of another corporation or of a 
partnership, joint venture, trust or other enterprise, including service with 
respect to employee benefit plans, and the basis of such Claim is alleged 
action or inaction in an official capacity  or in any other capacity while 
serving as such a director, officer, employee or agent, and Indemnitee shall be 
indemnified and held harmless by ARCO to the fullest extent permitted by the 
General Corporation Law of Delaware, as the same exists or may hereafter be 
amended (but, in the case of any such amendment with reference to events 
occurring prior to the effective date thereof, only to the extent that such 
amendment permits ARCO to provide broader indemnification rights than such law 
permitted ARCO to provide prior to such amendment), against all costs, charges, 
expenses, liabilities and losses (including attorneys' fees, judgments, fines, 
ERISA excise taxes or penalties and amounts paid in settlement) reasonably 
incurred or suffered by such person in connection therewith and such 
indemnification shall continue as to the Indemnitee when the Indemnitee has 
ceased to be a director or officer (or to serve another entity at the request 
of ARCO) and shall inure to the benefit of the Indemnitee's heirs, personal 
representative and estate.

    Section 3. REVIEWING PARTY. Notwithstanding the foregoing, the obligation 
of ARCO under Section 2 of this Agreement shall be subject to the condition 
that the Reviewing Party shall not have determined (in a written opinion, in 
any case in which the special, independent counsel referred to in Section 5 of 
this Agreement is involved) that the Indemnitee would not be permitted to be 
indemnified under applicable law.

    Section 4. RIGHT OF INDEMNITEE TO BRING SUIT. The rights of the Indemnitee 
to bring suit against ARCO under this Agreement include the following:

        a. If there has been no determination by the Reviewing Party or if the 
    Reviewing Party determines that the Indemnitee substantively would not be 
    permitted to be indemnified in whole or in part under applicable law, the 
    Indemnitee shall have the right to bring suit seeking an initial 
    determination by the court or challenging any such determination by the 
    Reviewing Party or any aspect thereof, and ARCO hereby consents to service 
    of process and to appear in any such proceeding. Any determination by the 
    Reviewing Party otherwise shall be conclusive and binding on ARCO and the 
    Indemnitee.

        b. If a claim for advances under Section 7 is not paid in full by ARCO 
    within sixty days after a written claim has been received by ARCO, the 
    Indemnitee may at any time thereafter bring suit against ARCO to recover 
    the unpaid amount. If successful in whole or in part, the Indemnitee shall 
    be entitled to be paid also the expense of prosecuting such claim.

        c. In any action brought by the Indemnitee to enforce a right to 
    indemnification hereunder, or by ARCO to recover payments by ARCO of 
    expenses incurred by the Indemnitee in connection with a Claim in advance 
    of its final disposition, the burden of proving that the Indemnitee is not 
    entitled to be indemnified under this Section or otherwise shall be on 
    ARCO. Neither the failure of ARCO (including its Board of Directors, 
    independent legal counsel, other Reviewing Party or its stockholders) to 
    have made a determination prior to the commencement of such action that 
    indemnification of the Indemnitee is proper in the circumstances because 
    the Indemnitee has met the applicable standard of conduct set forth in the 
    General Corporation Law of Delaware, nor an actual determination by the 
    Company (including its Board of Directors, independent legal counsel, other 
    Reviewing Party or its stockholders) that the Indemnitee has not met



                                       3
   4
such applicable standard of conduct, shall create a presumption that the
Indemnitee has not met the applicable standard of conduct or, in the case of
such an action brought by the Indemnitee, be a defense to the action.

     d. Notwithstanding any provisions to the contrary and except as provided in
this Section, ARCO shall indemnify the Indemnitee in connection with a
proceeding (or part thereof) initiated by the Indemnitee against ARCO only if
such proceeding (or part thereof) was authorized prior to its initiation by a
majority of the disinterested members of the Board of Directors of ARCO. The
rights to indemnification confirmed by this paragraph shall include the right to
be paid by ARCO any expenses incurred in defending such proceeding in advance of
its final disposition.

     Section 5. CHANGE IN CONTROL. ARCO agrees that if there is a Change in 
Control of ARCO (other than a Change in Control which has been approved by a 
majority of the persons surviving as Directors who comprised ARCO's Board of 
Directors immediately prior to such Change in Control) then with respect to all 
matters thereafter arising concerning the rights of the Indemnitee to indemnity 
payments and advances under this Agreement, ARCO shall seek legal advice only 
from special, independent counsel selected by the Indemnitee and approved by 
ARCO (which approval shall not be unreasonably withheld), and who has not 
otherwise performed services within the last 5 years for ARCO or any "person" 
referred to in clause (i) of Section 1a hereof or "other corporation" referred 
to in clause (iii) of that Section (other than in connection with such matters) 
or for the Indemnitee. Such counsel, among other things, shall render its 
written opinion to ARCO and the Indemnitee as to whether and to what extent the 
Indemnitee would be permitted to be indemnified under applicable law. ARCO 
agrees to provide full cooperation to and to pay the reasonable fees of the 
special, independent counsel referred to above and to indemnify fully such 
counsel against any and all expenses (including attorneys' fees), claims, 
liabilities and damages arising out of or relating to this Agreement or its 
engagement pursuant hereto.

     Section 6. INDEMNIFICATION FOR COSTS, CHARGES AND EXPENSES OF SUCCESSFUL 
PARTY. Notwithstanding the other provisions of this Agreement, to the extent 
that the Indemnitee has been successful on the merits or otherwise, including, 
without limitation, the dismissal of an action without prejudice, in defense of 
any Claim covered by this Agreement, or in defense of any claim, issue or 
matter therein, the Indemnitee shall be indemnified against all costs, charges 
and expenses, including attorneys' fees, actually and reasonably incurred by 
the Indemnitee or on Indemnitee's behalf in connection therewith.

     Section 7. ADVANCES. Expenses incurred by the Indemnitee in defending any 
Claim, including attorneys' fees, judgments, fines and amounts paid in 
settlements shall be paid by ARCO in advance of the final disposition of the 
Claim, provided, however, that if the General Corporation Law of Delaware 
requires, payment shall be made to or on behalf of the Indemnitee only upon 
delivery to ARCO of an undertaking, by or on behalf of the Indemnitee, to repay 
all amounts so advanced if it shall ultimately be determined that the 
Indemnitee is not entitled to be indemnified by ARCO under Delaware law.

     Section 8. PROCEDURE FOR INDEMNIFICATION. After the final disposition of 
any Claim covered by this Agreement, the Indemnitee shall send to ARCO a 
written request for any indemnification sought under this Agreement. No later 
than 30 days following receipt by ARCO of such request, ARCO shall deliver such 
request to an appropriate Reviewing Party for its review pursuant to this 
Agreement and shall cause the indemnification provided hereunder to be 
authorized and paid, so long as during such 30-day period, the Reviewing Party 
has not determined that indemnification would not be permitted under applicable 
law. The Indemnitee and Indemnitee's counsel shall be given an opportunity to 
be heard and to present evidence on the Indemnitee's behalf in connection with 
consideration by the Reviewing Party.

     Section 9. ESTABLISHMENT OF TRUST. In the event of a Potential Change in 
Control, ARCO shall, upon written request by the indemnitee, create a trust for 
the benefit of the Indemnitee and from time to time upon written request of the 
Indemnitee shall fund such trust in an amount sufficient to satisfy any and all 
expenses reasonably anticipated at the time of each such request to be incurred 
in connection with investigating, preparing for and defending any Claim, and 
any and all judgments, fines, penalties and settlement amounts of any and all 
Claims covered by this Agreement, from time to time actually paid or claimed, 
reasonably anticipated or proposed to be paid. The terms of the trust shall 
provide that upon a Change in Control (A) the trust shall not be revoked or the 
principal thereof invaded, without the written consent of the Indemnitee, (B) 
the trustee shall advance within two business days of a request by the 
Indemnitee any and all expenses to the Indemnitee (and the Indemnitee hereby 
agrees to reimburse the trust under the circumstances under which the 
Indemnitee would be required to reimburse ARCO under Section 2 of this 
Agreement), (C) the trust shall continue to be funded by ARCO in accordance 
with the funding obligation set forth above, (D) the trustee shall promptly pay 
to the Indemnitee all amounts for which the Indemnitee shall be entitled to 
indemnification pursuant to this Agreement or otherwise, and (E) all unexpended 
funds in such trust shall revert to ARCO upon a final determination, by a court 
of competent jurisdiction, that the Indemnitee has been fully indemnified under 
the terms of this Agreement. The trustee shall be chosen by the Indemnitee. 
Nothing in this Section 9 shall relieve ARCO of any of its obligations under 
this Agreement.

     Section 10. INSURANCE. To the extent ARCO maintains an insurance policy or 
policies providing directors' and officers' liability insurance, the Indemnitee 
shall be covered by such policy or policies, in accordance with its or their 
terms, to the maximum extent of the coverage available for ARCO's directors or 
officers.

     Section 11. NOTICE TO COMPANY. The Indemnitee must provide prompt written 
notice to ARCO of any Claim in connection with which the Indemnitee may assert 
a right to be indemnified hereunder; however, failure to provide such notice 
shall not be construed as a waiver of any right of the Indemnitee to an advance 
or indemnification hereunder.

     Section 12. OTHER RIGHTS; CONTINUATION OF RIGHT TO INDEMNIFICATION. The 
indemnification and advances provided by this Agreement shall not be deemed 
exclusive of any other rights to which the Indemnitee seeking indemnification 
may be entitled under any law (common or statutory), provision of ARCO's 
Certificate of Incorporation or By-Laws, vote of stockholders or disinterested 
directors, or otherwise, both as to action in the Indemnitee's official 
capacity and as to action in another capacity while holding office or while 
employed by or acting as agent for ARCO, and shall continue as to a person who 
has ceased to be a director or officer, and shall inure to the benefit of the 
estate, heirs, executors and administrators of the Indemnitee.

     Section 13. SUBROGATION. In the event of payment under this Agreement, 
ARCO shall be subrogated to the extent of such payment to all of the rights of 
recovery of the Indemnitee, who shall execute all papers required and shall do 
everything that may be necessary to secure such rights, including the execution 
of such documents necessary to enable ARCO effectively to bring suit to enforce 
such rights.

     Section 14. NO DUPLICATION OF PAYMENTS. ARCO shall not be liable under 
this Agreement to make any payment in connection with any claim made against 
the Indemnitee to the extent the Indemnitee has otherwise actually received 
payment (under any insurance policy or otherwise) of the amounts otherwise 
indemnifiable hereunder.

     Section 15. AMENDMENTS. This Agreement may not be amended without the 
agreement in writing of ARCO and the Indemnitee.

     Section 16. SAVINGS CLAUSE. If this Agreement or any portion hereof shall 
be deemed invalid, illegal or unenforceable in any respect, the validity, 
legality and enforceability of the remaining provisions contained herein shall 
not in any way be affected or impaired thereby, 



                                       5
   6
and ARCO  shall nevertheless indemnify the Indemnitee as to costs, charges and
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement with respect to any Claim to the full extent permitted by any
applicable portion of this Agreement that shall not have been invalidated and to
the full extent permitted by applicable law.

     Section 17. SURVIVAL CLAUSE. ARCO acknowledges that in continuing to
provide services to ARCO, the Indemnitee is relying on this Agreement.
Accordingly, ARCO agrees that its obligations hereunder will survive (A) any
actual or purported termination of this Agreement by ARCO or its successors or
assigns whether by operation of law or otherwise, and (B) termination of the
Indemnitee's services to ARCO, whether such services were terminated by ARCO or
the Indemnitee, with respect to any Claim, whether or not such Claim is made,
threatened or commenced before or after the actual purported termination of this
Agreement or the termination of the Indemnitee's services to ARCO.

     Section 18. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon
and inure to the benefit of and be enforceable by the parties hereto and their
respective successors, assigns, including any direct or indirect successor by
purchase, merger, consolidation or otherwise to all or substantially all of the
business and/or assets of ARCO, spouses, heirs, and personal and legal
representatives. ARCO shall require and cause any successor (whether direct or
indirect by purchase, merger, consolidation or otherwise) to all, substantially
all of the business and/or assets of ARCO, by written agreement in form and
substance satisfactory to the Indemnitee, expressly to assume and agree to
perform this Agreement in the same manner and to the same extent that ARCO would
be required to perform if no such succession had taken place.

     Section 19. GOVERNING LAW. This Agreement shall be governed in all
respects, including validity, interpretation and effect, by the laws of the
State of Delaware (without giving effect to the provisions thereof relating to
conflicts of law).

     IN WITNESS WHEREOF, this Agreement has been executed by the parties
thereto, and in the case of ARCO, by a duly authorized officer thereof on its
behalf.
