EXHIBIT 10.15

                       FORM OF INDEMNIFICATION AGREEMENT



       THIS INDEMNIFICATION AGREEMENT ("Agreement") is made as of this ______
     day of _______________, 19___, by and between Sun Company, Inc., a
     Pennsylvania corporation (the "Company") and _____________________________
     ("Indemnitee").

       WHEREAS, the Company and Indemnitee recognize the increasing difficulty
     in obtaining directors' and officers' liability insurance, the significant
     increases in the cost of such insurance and the general reduction in the
     coverage of such insurance; and

       WHEREAS, the Company and Indemnitee further recognize the substantial
     increase in corporate litigation, in general, subjecting officers and
     directors to expensive litigation risks at the same time as liability
     insurance has been severely limited; and

       WHEREAS, Indemnitee does not regard the current protection available as
     adequate given the present circumstances, and Indemnitee and other officers
     and directors of the Company may not be willing to serve as officers and
     directors without adequate protection; and

       WHEREAS, the Company desires to attract and retain the services of highly
     qualified individuals, such as Indemnitee, to serve as officers and
     directors of the Company and to indemnify its officers and directors so as
     to provide them with the maximum protection permitted by law.

       NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

       1.   INDEMNIFICATION.

            (a)  Third Party Proceedings.  The Company shall indemnify
     Indemnitee if Indemnitee is or was a party or is threatened to be made a
     party to any threatened, pending or completed action, suit or proceeding,
     whether civil, criminal, administrative or investigative (other than an
     action by or in the right of the Company) by reason of the fact that
     Indemnitee is or was a director, officer, employee or agent of the Company,
     or any affiliate of the Company, by reason of any action or inaction on the
     part of Indemnitee while an officer or director, or by reason of the fact
     that Indemnitee is or was serving at the request of the Company as a
     director, officer, employee or agent

 
     of another corporation, partnership, joint venture, trust or other
     enterprise, against expenses (including attorneys' fees), judgments, fines
     and amounts paid in settlement (if such settlement is approved pursuant to
     Section 2(f) hereof) actually and reasonably incurred by Indemnitee in
     connection with such action, suit or proceeding if Indemnitee acted in good
     faith and in a manner Indemnitee reasonably believed to be in or not
     opposed to the best interests of the Company, and, with respect to any
     criminal action or proceeding, had no reasonable cause to believe
     Indemnitee's conduct was unlawful.  The termination of any action, suit or
     proceeding by judgment, order, settlement, conviction, or upon a plea of
     nolo contendere or its equivalent, shall not, of itself, create a
     presumption that Indemnitee did not act in good faith and in a manner which
     Indemnitee reasonably believed to be in or not opposed to the best
     interests of the Company, and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that Indemnitee's conduct was
     lawful.

            (b)  Proceedings By or in the Right of the Company. The Company
     shall indemnify Indemnitee if Indemnitee was or is a party or is threatened
     to be made a party to any threatened, pending or completed action or suit
     by or in the right of the Company or any subsidiary of the Company to
     procure a judgment in its favor by reason of the fact that Indemnitee is or
     was a director, officer, employee or agent of the Company, or any affiliate
     of the Company, by reason of any action or inaction on the party of
     Indemnitee while an officer or director or by reason of the fact that
     Indemnitee is or was serving at the request of the Company as a director,
     officer, employee or agent of another corporation, partnership, joint
     venture, trust or other enterprise, against expenses (including attorneys'
     fees) and amounts paid in settlement (if such settlement is approved
     pursuant to Section 2(f) hereof) actually and reasonably incurred by
     Indemnitee in connection with the defense or settlement of such action or
     suit if Indemnitee acted in good faith and in a manner Indemnitee
     reasonably believed to be in or not opposed to the best interests of the
     Company, except that no indemnification shall be made in respect of any
     claim, issue or matter as to which Indemnitee shall have been adjudged to
     be liable to the Company unless and only to the extent that the court in
     which such action or suit was brought shall determine upon application
     that, despite the adjudication of liability but in view of all the
     circumstances of the case, Indemnitee is fairly and reasonably entitled to
     indemnity for such expenses which the court shall deem proper.

 
            (c)  Mandatory Indemnification.  To the extent that Indemnitee has
     been successful on the merits or otherwise in defense of any action, suit
     or proceeding referred to in Sections 1(a) and 1(b) or the defense of any
     claim, issue or matter therein, Indemnitee shall be indemnified against
     expenses (including attorneys' fees) actually and reasonably incurred by
     Indemnitee in connection therewith.  For purposes of this Section 1(c), the
     term "successful on the merits or otherwise" shall include, but not be
     limited to, (i) any termination, withdrawal, or dismissal (with or without
     prejudice) of any claim, action, suit or proceeding against Indemnitee
     without any express finding of liability or guilt against him, or (ii) the
     expiration of a reasonable period of time after the making of any claim or
     threat of an action, suit or proceeding without the institution of the same
     and without any promise or payment made to induce a settlement.

       2.   EXPENSES AND INDEMNIFICATION PROCEDURE.

            (a)  Advancement of Expenses.  The Company shall advance all
     reasonable expenses incurred by Indemnitee in connection with the
     investigation, defense, settlement or appeal of any civil or criminal
     action, suit or proceeding referenced in Section 1(a) or (b) hereof.  For
     purposes of any advancement hereunder, the Indemnitee shall be deemed to
     have acted (i) in good faith and in a manner he reasonably believed to be
     in or not opposed to the best interest of the Company, and (ii) with
     respect to any criminal action or procedure, to have had no reasonable
     cause to believe his conduct was unlawful if, under either (i) or (ii), his
     action is based on the records or books of account of the Company, or the
     records or books of account of another corporation, partnership, joint
     venture, trust or another enterprise (collectively, the "other
     enterprises"), including financial statements, or on information supplied
     to him by the officers of the Company or other enterprises in the course of
     their duties, or on the advice of legal counsel for the Company or other
     enterprises or on information or records given or reports made to the
     Company or other enterprises by an independent certified public accountant
     or by an appraiser or other expert selected with reasonable care by the
     Company or other enterprises.  Indemnitee hereby undertakes to repay such
     amounts advanced only if, and to the extent that, it shall ultimately be
     determined that Indemnitee is not entitled to be indemnified by the Company
     as authorized hereby.

            (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
     condition precedent to his right to be indemnified under this Agreement,
     give the Company notice in writing as soon

 
     as practicable of any claim made against Indemnitee for which
     indemnification will or could be sought under this Agreement. Notice to the
     Company shall be directed to Sun Company, Inc., 1801 Market Street,
     Philadelphia, PA 19103, Attention: Vice President and General Counsel (or
     such other address as the Company may from time to time designate in
     writing to Indemnitee).  Notice shall be deemed received on the third
     business day after the date postmarked if sent by domestic certified or
     registered mail, properly addressed; otherwise, notice shall be deemed
     received when such notice shall actually be received by the Company.  In
     addition, Indemnitee shall give the Company such information and
     cooperation as it may reasonably require and as shall be within
     Indemnitee's power.

            (c)  Procedure.  Any indemnification and advances provided for in
     Section 1 hereof and this Section 2 shall be made no later than forty-five
     (45) days after receipt of the written request of Indemnitee, coupled with
     appropriate documentation to support the requested payment.  If a claim
     under this Agreement, under any statute, or under any provision of the
     Company's Certificate of Incorporation or Bylaws providing for
     indemnification is not paid in full by the Company within forty-five (45)
     days after receipt of a fully documented written request for payment
     thereof has first been received by the Company, Indemnitee may, but need
     not, at any time thereafter bring an action against the Company to recover
     the unpaid amount of the claim and, subject to Section 13 hereof,
     Indemnitee shall also be entitled to be paid for the expenses (including
     attorneys' fees) of bringing such action.  It shall be a defense to any
     such action (other than an action brought to enforce a claim for expenses
     incurred in connection with any action, suit or proceeding in advance of
     its final disposition) that Indemnitee has not met the standards of conduct
     which make it permissible under applicable law for the Company to indemnify
     Indemnitee for the amount claimed, but the burden of proving such defense
     shall be on the Company, and Indemnitee shall be entitled to receive
     interim payments of expenses pursuant to Section 2(a) hereof unless and
     until such defense may be finally adjudicated by court order or judgment
     from which no further right of appeal exists.  It is the parties' intention
     that if the Company contests Indemnitee's right to indemnification, the
     question of Indemnitee's right to indemnification shall be for the court to
     decide, and neither the failure of the Company (including its Board of
     Directors, any committee or subgroup of the Board of Directors, independent
     legal counsel, or its stockholders) to have made a determination that
     indemnification of Indemnitee is proper in the circumstances because
     Indemnitee has met the

 
     applicable standard of conduct required by applicable law, nor an actual
     determination by the Company (including its Board of Directors, any
     committee or subgroup of the Board of Directors, independent legal counsel,
     or its stockholders) that Indemnitee has not met such applicable standard
     of conduct, shall create a presumption that Indemnitee has or has not met
     the applicable standard of conduct.

            (d)  Notice to Insurers.  If, at the time of the receipt of a notice
     of claim pursuant to Section 2(b) hereof, the Company has directors' and
     officers' liability insurance in effect, the Company shall give prompt
     notice of the commencement of such proceeding to the insurers in accordance
     with the procedures set forth in the respective policies.  The Company
     shall thereafter take all necessary or desirable action to cause such
     insurers to pay, on behalf of Indemnitee, all amounts payable as a result
     of such proceeding in accordance with the terms of such policies.

            (e)  Selection of Counsel.  If the Company shall be obligated under
     Section 2(a) hereof to pay the expenses of any proceeding against
     Indemnitee, the Company, if appropriate, shall be entitled to assume the
     defense of such proceeding, with counsel approved by Indemnitee, upon the
     delivery to Indemnitee of written notice of its election to do so.  After
     delivery of such notice, approval of such counsel by Indemnitee and the
     retention of such counsel by the Company, the Company will not be liable to
     Indemnitee under this Agreement for any fees of counsel subsequently
     incurred by Indemnitee with respect to the same proceeding; provided that
     (i) Indemnitee shall have the right to employ separate counsel in any such
     proceeding at Indemnitee's expense; and (ii) if (A) the employment of
     counsel by Indemnitee has been previously authorized by the Company, (B)
     Indemnitee shall have reasonably concluded that there may be a conflict of
     interest between the Company and Indemnitee in the conduct of any such
     defense, or (C) the Company shall not, in fact, have employed counsel to
     assume the defense of such proceeding, then the reasonable fees and
     expenses of Indemnitee's counsel shall be at the expense of the Company.

            (f)  Settlements.  The Company shall not be liable to Indemnitee
     under this Agreement for any amounts paid in settlement of any action or
     claim effected without its written consent. The Company shall not settle
     any action or claim in any manner which would impose any penalty or
     limitation on Indemnitee without Indemnitee's written consent. Neither the
     Company nor Indemnitee will reasonably withhold consent to any proposed
     settlement.

 
            (g)  Change in Control.  If, at any time subsequent to the date of
     this Agreement, continuing directors do not constitute a majority of the
     members of the Board of Directors, or there is otherwise a change in
     control of the Company (as contemplated by Item 403(c) of Regulation S-K
     under the Securities Act of 1933, as amended, and the Securities Exchange
     Act of 1934, as amended), then upon the request of Indemnitee, the Company
     shall cause the determination of indemnification and advances required by
     Section 2 hereof to be made by a third-party (mutually agreed upon by the
     parties or failing such agreement, as determined by the Chief Judge of the
     Federal District Court for the Eastern District of Pennsylvania).  The fees
     and expenses incurred by the third party in making the determination of
     indemnification and advances shall be borne solely by the Company.  If such
     third party is unwilling and/or unable to make the determination of
     indemnification and advances, then the Company shall cause the
     indemnification and advances to be made by a majority vote or consent of a
     Board committee consisting solely of continuing directors.  For purposes of
     this Agreement, a "continuing director" means either a member of the Board
     at the date of this Agreement or a person nominated to serve as a member of
     the Board by a majority of then-continuing directors.

       3.   ADDITIONAL INDEMNIFICATION RIGHTS:

            (a)  Scope.  Notwithstanding any other provision of this Agreement,
     the Company shall indemnify Indemnitee to the fullest extent permitted by
     law, notwithstanding that such indemnification is not specifically
     authorized by the other provisions of this Agreement, the Company's
     Certificate of Incorporation, the Company's Bylaws or by statute.  In the
     event of any change, after the date of this Agreement, in any applicable
     law, statute, or rule which expands the right of a Pennsylvania corporation
     to indemnify a member of its board of directors or an officer, such changes
     shall be, ipso facto, within the purview of Indemnitee's rights and
     Company's obligations under this Agreement.  In the event of any change in
     any applicable law, statute or rule which narrows the right of a
     Pennsylvania corporation to indemnify a member of its board of directors or
     an officer, such changes (to the extent not otherwise required by such law,
     statute or rule to be applied to this Agreement) shall have no effect on
     this Agreement or the parties' rights and obligations hereunder.

 
          (b) Non-exclusivity.  The indemnification provided by this
     Agreement shall not be deemed exclusive of any rights to which an
     Indemnitee may be entitled under the Company's Certificate of
     Incorporation, its Bylaws, any agreement, any vote of stockholders or
     disinterested directors, the Pennsylvania Business Corporation Law of 1988,
     as amended, or otherwise, both as to action in Indemnitee's official
     capacity and as to action in another capacity while holding such office.

       4. CONTINUATION OF INDEMNITY.  All agreements and obligations of the
     Company contained herein shall continue during the period Indemnitee is a
     director, officer, employee or agent of the Company (or is or was serving
     at the request of the Company as a director, officer, employee or agent of
     other enterprises) and shall continue thereafter, so long as Indemnitee
     shall be subject to any possible claim or threatened, pending or completed
     action, suit or proceeding, whether civil, criminal or investigative, by
     reason of the fact that Indemnitee was a director, officer, employee or
     agent of the Company or serving in any other capacity referred to herein.

       5. PARTIAL INDEMNIFICATION.  If Indemnitee is entitled under any
     provision of this Agreement to indemnification by the Company for some or a
     portion of the expenses, judgments, fines or penalties actually or
     reasonably incurred by him in the investigation, defense, appeal or
     settlement of any civil or criminal action, suit or proceeding, but not for
     the total amount thereof, the Company shall nevertheless indemnify
     Indemnitee for the portion of such expenses, judgments, fines or penalties
     to which Indemnitee is entitled.

       6. MUTUAL ACKNOWLEDGMENT.  Both the Company and Indemnitee acknowledge
     that, in certain instances, federal law or public policy may override
     applicable state law and prohibit the Company from indemnifying its
     directors and officers under this Agreement or otherwise.  For example, the
     Company and Indemnitee acknowledge that the Securities and Exchange
     Commission (the "SEC") has taken the position that indemnification is not
     permissible for liabilities arising under certain federal securities laws,
     and federal legislation prohibits indemnification for certain ERISA
     violations.  Indemnitee understands and acknowledges that the Company has
     undertaken with the SEC to submit the question of indemnification to a
     court in certain circumstances for a determination of the Company's right
     under public policy to indemnify Indemnitee.

 
       7. OFFICER AND DIRECTOR LIABILITY INSURANCE.  The Company shall, from
     time to time, make the good faith determination whether or not it is
     practicable for the Company to obtain and maintain a policy or policies of
     insurance with reputable insurance companies providing the officers and
     directors of the Company with coverage for losses from wrongful acts, or to
     ensure the Company's performance of its indemnification obligations under
     this Agreement.  Among other considerations, the Company will weigh the
     costs of obtaining such insurance coverage against the protection afforded
     by such coverage.  In all policies of directors' and officers' liability
     insurance, Indemnitee shall be insured in such a manner as to provide
     Indemnitee the same rights and benefits as are accorded to the most
     favorably insured of the Company's directors, if Indemnitee is a director;
     or of the Company's officers, if Indemnitee is not a director of the
     Company but is an officer; or one of the Company's key employees, if
     Indemnitee is not an officer or director but is a key employee.
     Notwithstanding the foregoing, the Company shall have no obligation to
     obtain or maintain such insurance if the Company determines in good faith
     that such insurance is not reasonably available, if the premium costs for
     such insurance are disproportionate to the amount of coverage provided, if
     the coverage provided by such insurance is limited by exclusions so as to
     provide an insufficient benefit, or Indemnitee is covered by similar
     insurance maintained by an affiliate of the Company.

       8. SEVERABILITY.  Nothing in this Agreement is intended to require or
     shall be construed as requiring the Company to do or fail to do any act in
     violation of applicable law. The Company's inability, pursuant to court
     order, to perform its obligations under this Agreement shall not constitute
     a breach of this Agreement. The provisions of this Agreement shall be
     severable as provided in this Section 8. If this Agreement or any portion
     hereof shall be invalidated on any ground by any court of competent
     jurisdiction, then the Company shall nevertheless indemnify Indemnitee to
     the full extent permitted by any applicable portion of this Agreement that
     shall not have been invalidated, and the balance of this Agreement not so
     invalidated shall be enforceable in accordance with its terms.

 
         9. EXCEPTIONS.  Any other provision herein to the contrary
     notwithstanding, the Company shall not be obligated pursuant to the terms
     of this Agreement:

            (a)  Claims Initiated by Indemnitee. To indemnify or advance
     expenses to Indemnitee with respect to proceedings or claims initiated or
     brought voluntarily by Indemnitee and not by way of defense, except with
     respect to proceedings brought to establish or enforce a right to
     indemnification under this Agreement or any other statute or law or
     otherwise as required under the Pennsylvania Business Corporation Act of
     1988, as amended, but such indemnification or advancement of expenses may
     be provided by Company in specific cases if the Board of Directors finds it
     to be appropriate;

            (b)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
     incurred by Indemnitee with respect to any proceeding instituted by
     Indemnitee to enforce or interpret this Agreement, if a court of competent
     jurisdiction determines that each of the material assertions made by
     Indemnitee in such proceeding was not made in good faith or was frivolous;

            (c)  Insured Claims. To indemnify Indemnitee for expenses or
     liabilities of any type whatsoever (including, but not limited to,
     judgments, fines, ERISA excise taxes or penalties, and amounts paid in
     settlement) which have been paid directly to Indemnitee by an insurance
     carrier under a policy of officers' and directors' liability insurance
     maintained by the Company or other enterprise; or

            (d)  Claims Under Section 16(b). To indemnify Indemnitee for
     expenses or the payment of profits arising from the purchase and sale by
     Indemnitee of securities in violation of Section 16(b) of the Securities
     Exchange Act of 1934, as amended, or any similar successor statute.

       10.  CONSTRUCTION OF CERTAIN PHRASES.

            (a)  For purposes of this Agreement, references to the "Company"
     shall include, in addition to the resulting corporation, any constituent
     corporation (including any constituent of a constituent) absorbed in a
     consolidation or merger which, if its separate existence had continued,
     would have had power and authority to indemnify its directors, officers,
     and employees or agents, so that if Indemnitee is or was a director,
     officer, employee or agent of such constituent corporation, or is or was
     serving at the request of such constituent corporation as

 
     a director, officer, employee or agent of other enterprises, Indemnitee
     shall stand in the same position under the provisions of this Agreement
     with respect to the resulting or surviving corporation as Indemnitee would
     have with respect to such constituent corporation if its separate existence
     had continued.

            (b)  For purposes of this Agreement, references to "other
     enterprises" shall include employee benefit plans; references to "fines"
     shall include any excise taxes assessed on Indemnitee with respect to an
     employee benefit plan; and reference to "serving at the request of the
     Company" shall include any service as a director, officer, employee or
     agent of the Company which imposes duties on, or involves services by,
     Indemnitee with respect to an employee benefit plan, its participants, or
     beneficiaries; and, if Indemnitee acted in good faith and in a manner
     Indemnitee reasonably believed to be in the interest of the participants
     and beneficiaries of an employee benefit plan, Indemnitee shall be deemed
     to have acted in a manner "not opposed to the best interests of the
     Company" as referred to in this Agreement.

            (c)  For the purposes of this Agreement, references to "affiliates"
     shall mean any entity which, directly or indirectly, is in the control of,
     is controlled by, or is under common control with, the Company.

       11.  COUNTERPARTS.  This Agreement may be executed in one or more
     counterparts, each of which shall constitute an original.

       12.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon and
     inure to the benefit of the Company and its successors and assigns, and
     Indemnitee and Indemnitee's estate, heirs, legal representatives and
     assigns.

       13.  ATTORNEYS' FEES.  If any action is instituted by Indemnitee under
     this Agreement to enforce or interpret any of the terms hereof, Indemnitee
     shall be entitled to be paid all court costs and expenses, including
     reasonable attorneys' fees, incurred by Indemnitee with respect to such
     action, unless as a part of such action, the court of competent
     jurisdiction determines that each of the material assertions made by
     Indemnitee as a basis for such action was not made in good faith or was
     frivolous.  In the event of an action instituted by or in the name of the
     Company under this Agreement or to enforce or

 
     interpret any of the terms of this Agreement, Indemnitee shall be entitled
     to be paid all court costs and expenses, including attorneys' fees,
     incurred by Indemnitee in defense of such action (including with respect to
     Indemnitee's counterclaims and cross-claims made in such action), unless as
     a part of such action the court determines that each of Indemnitee's
     material defenses to such action was made in bad faith or was frivolous.

       14.  NOTICE.  All notices, requests, demands and other communications
     under this Agreement shall be in writing and, unless otherwise provided,
     shall be deemed duly given (a) if delivered by hand and receipted for by
     the party addressee, on the date of such receipt, or (b) if mailed by
     domestic certified or registered mail with postage prepaid, on the third
     business day after the date postmarked.  The address for notice to the
     Company shall be as set forth in Section 2(b) hereof, and the address for
     notice to Indemnitee shall be as set forth on the signature page of this
     Agreement, or as subsequently modified by written notice.

       15.  CONSENT TO JURISDICTION.  The Company and Indemnitee each hereby
     irrevocably consent to the jurisdiction of the courts of the Commonwealth
     of Pennsylvania for all purposes in connection with any action or
     proceeding which arises out of or relates to this Agreement.  Any action
     instituted under this Agreement shall be brought only in the state courts
     of the Commonwealth of Pennsylvania.

       16.  Subrogation.  In the event of payment under this Agreement, Company
     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 Company effectively to
     bring suit to enforce such rights.

       17.  CHOICE OF LAW.  This Agreement shall be governed by and its
     provisions construed in accordance with the laws of the Commonwealth of
     Pennsylvania, as applied to contracts between Pennsylvania residents
     entered into and to be performed within Pennsylvania.

 
       IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
     the date first above written.
