              1. STOCK OWNERSHIP. During the term of this June 1999 Agreement,
                 Parent will own all of the voting common stock of Subsidiary
                 and The Detroit Edison Company ("DECo") now or hereafter issued
                 and outstanding.

              2. NEGATIVE PLEDGE. During the term of this June 1999 Agreement,
                 Parent will not create or suffer to exist any lien, security
                 interest or other charge or encumbrance, upon or with respect
                 to any voting common stock of DECo from time to time owned by
                 Parent or any capital stock of Subsidiary from time to time
                 owned by Parent, provided, however, that any restriction on the
                 payment of dividends by DECo or Subsidiary contained in any
                 subordinated debt instrument, preferred stock or preference
                 stock of DECo or Subsidiary shall not constitute a lien,
                 security interest or other charge or encumbrance,

              3. LIQUIDITY PROVISION. If, during the term of this June 1999
                 Agreement, Subsidiary is unable to make timely payment of such
                 amounts as shall be due and payable pursuant to a guarantee
                 issued by Subsidiary and running to the benefit of any obligee
                 ("Obligee") of Trading, then, Parent promptly shall provide to
                 Subsidiary, at its request, such funds (in the form of cash or
                 liquid assets) in an amount sufficient to permit Subsidiary to
                 make timely payment in respect of such guarantee. If such funds
                 are advanced to Subsidiary as a loan, such loan shall be on
                 such terms and conditions, including maturity and rate of
                 interest, as Parent and Subsidiary shall agree. Notwithstanding
                 the foregoing, any such loan shall be subordinated to any and
                 all obligations of Subsidiary owing to any Lender pursuant to
                 the terms of the Credit Agreement and such amounts as shall be
                 owing pursuant to guarantees issued by Subsidiary for the
                 benefit of Obligees of Trading. Each of the parties hereto
                 acknowledges that Parent's obligations hereunder do not
                 constitute a guarantee by Parent of the obligations of
                 Subsidiary.

              4. WAIVERS. Parent hereby waives any failure or delay on the part
                 of Subsidiary in asserting or enforcing any of its rights or in
                 making any claims or demands hereunder.

              5. AMENDMENT, - SUSPENSION. This June 1999 Agreement may be
                 amended or terminated at any time by written amendment or
                 agreement signed by both parties; provided, however, that
                 except as set forth in the next succeeding sentence, no
                 amendment to the June 1999 Agreement which adversely affects
                 the rights of

                                       2

                 Subsidiary or any Obligee and no termination of this June 1999
                 Agreement shall be effective as to Subsidiary or any Obligee
                 until such time as all amounts contingently owing to all
                 Obligees by Subsidiary on the date of such amendment or
                 termination shall have been paid in full or adequate provision
                 has been made for the payment of same unless such Obligees
                 shall consent in writing to the contrary.

              6. RIGHTS OF OBLIGEE. Subsidiary hereby grants to the Obligees,
                 Subsidiary's rights under Sections 1, 2, 3 and 4 of this June
                 1999 Agreement, and, if Subsidiary fails or refuses to take
                 timely action to enforce its rights under Sections 1, 2, 3 or 4
                 of this June 1999 Agreement, any Obligee may enforce such
                 rights on behalf of Subsidiary directly against Parent. Parent
                 hereby consents to such grant.

              7. PARITY. Parent's obligations hereunder shall be pari passau
                 with Parent's obligations (a) under that certain Support
