         WHEREAS, Subsidiary may from time to time make borrowings from the

         WHEREAS, the parties receiving guarantees from Subsidiary of the
obligations of Trading and/or DTE-CoEnergy may rely upon this 1999 Agreement in
extending credit to Trading and/or DTE-CoEnergy and in accepting Subsidiary's
guarantee(s);

         NOW, THEREFORE, in consideration of the premises, and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Parent and Subsidiary agree as follows:

         1.   STOCK OWNERSHIP. During the term of this 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 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 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 and/or DTE-CoEnergy, 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 and/or DTE-CoEnergy. 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 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 1999 Agreement which
              adversely affects the rights of Subsidiary or any Obligee and no
              termination of this 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 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
              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 Agreement
              ("Credit Agreement Support Agreement") dated as of January 19,
              1999, between Parent and Subsidiary and relating to the Credit
              Agreement and (b) under such additional support agreements as are
              contemplated by the Credit Agreement Support Agreement.
