                 D.  On September 21, 1995, pursuant to a letter of instruction
dated such date from the Owner Participant to the Owner Trustee, the Owner

of the Lease if the assumptions set forth in Schedule 1 attached hereto at the
time of the pricing of the refinancing contemplated hereby shall thereafter
prove to be incorrect at the time of the closing of such refinancing.

limitation as to time, to assume liability for, and to indemnify, defend,
protect, save and hold harmless (to the fullest extent permitted by law) Owner
Participant and Owner Trustee, and the officers, directors, agents and
employees of each of them and each Person who controls each of them (within the
meaning of Section 15 of the Securities Act or Section 20 of the Securities
Exchange Act) (each an "Indemnified Party"), on an after-tax basis from and
against, any and all Claims of or against Owner Participant or Owner Trustee,
whether or not Owner Participant and Owner Trustee shall also be indemnified as
to any such Claim by any other Person, in any way relating to or arising in
connection with the offer or sale of the 1995 Series Bonds under the Securities
Act, or any other applicable law relating to the offering and sale of the 1995
Series Bonds including, without limitation, all Claims arising out of or based
upon any untrue or alleged untrue statement of a material fact contained in any
registration statement, prospectus or form of prospectus, or arising out of or
based upon, in the case of the registration statement, any omission or alleged
omission of a material fact required to be stated therein or necessary to make
the statements therein not misleading and, in the case of any prospectus or
form of prospectus, any omission therein or alleged omission of material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading
except, in either case:  (i) to the extent that the same arise out of or are
based upon information furnished in writing to Lessee by such Indemnified Party
expressly for use therein or otherwise in connection with the offer and sale of
the 1995 Series Bonds; and (ii) any Claim resulting solely from breach by Owner
Participant or Owner

Trustee (which, in the case of Owner Trustee, shall have resulted from its
gross negligence or willful misconduct) of any of its representations,
warranties or covenants contained in any document or Certificate delivered by
the Owner Trustee or Owner Participant in connection with the issuance of the
1995 Series Bonds in any material respect.  When an Indemnified Party has
received indemnification payments from Lessee in full satisfaction of the
indemnification provisions of this Supplement No. 1, Lessee shall be
subrogated, to the extent of such indemnity paid, to such Indemnified Party's
rights with respect to the transaction or event requiring or giving rise to
such indemnity, other than such rights against such Indemnified Party to the
extent they are indemnified hereunder.  Nothing contained herein shall be
construed as a guaranty of (A) payment of any of the Bonds; or (B) the Useful
Life of the Facilities; or (C) the value of the Leased Assets upon termination
of the Basic Term or any Renewal Term.

                 (b)  Conduct of Indemnification Proceedings.  If any
Indemnified Party shall be entitled to indemnity hereunder, such Indemnified
Party shall give prompt notice to Lessee of the commencement of any proceeding
with respect to which such Indemnified Party seeks indemnification or
contribution pursuant to hereto; provided, however, that the failure so to
notify Lessee shall not relieve Lessee from any obligation or liability except
to the extent that Lessee has been prejudiced by such failure.  Lessee shall
have the right, exercisable by giving written notice to such Indemnified Party
promptly after the receipt of written notice from such Indemnified Party of
such proceeding, to assume, at the Lessee's expense, the defense of any such
proceedings, with counsel reasonably satisfactory to such Indemnified Party;
provided, however, that an Indemnified Party or Parties (if more than one such
Indemnified Party is named in any proceeding) shall have the right to employ
separate counsel in any such proceedings and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party or Parties unless: (1) Lessee agrees in writing to pay
such fees and expenses; or (2) Lessee fails promptly to assume the defense of
such proceeding or fails to employ counsel reasonably satisfactory to such
Indemnified Party or Parties; or (3) the defendants in such proceeding shall
include both Lessee and the Indemnified Party or Parties and the Indemnified
Party or Parties shall have been





                                     - 8 -
   11
advised by counsel in its reasonable judgement that there is reasonably likely
to be a conflict between the positions of Lessee or an Affiliate of Lessee and
such Indemnified Party or Parties in conducting the defense of such action or
proceeding or that there are reasonably likely to be legal defenses available
to such Indemnified Party or Parties different from or in addition to those
available to the Lessee or such Affiliate; or (4) the indemnified Party or
Parties shall have been advised by counsel that there exists a risk of criminal
liability to such Indemnified Party or Parties, in which case, if such
Indemnified Party or Parties notifies Lessee in writing that it elects to
employ separate counsel at the expense of Lessee, Lessee shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
and must be reasonably satisfactory to Lessee, it being understood, however,
that, unless there exists a conflict among Indemnified Parties, Lessee shall
not, in connection with any one such proceeding or separate but substantially
similar or related proceedings, arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (together with appropriate local counsel) at any time for
such Indemnified Party or Parities, or for fees and expenses that are not
reasonable.  Whether or not such defense is assumed by Lessee, Lessee or
Indemnified Party or Parties will not be subject to any liability for any
settlement made without its or their consent (but such consent will not be
unreasonably withheld).  Lessee shall not be liable for any settlement of any
such action or proceeding effected without its written consent, but if settled
with its written consent, or if there be a final judgment for the plaintiff in
any such action or proceeding, Lessee agrees subject to the exception and
limitations set forth above, to indemnify and hold harmless each Indemnified
Party from and against any loss or liability by reason of such settlement or
judgment.  Lessee shall not consent to the entry of any judgment or enter into
any settlement that does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party or Parties of a
release, in form and substance satisfactory to the Indemnified Party or
Parties, from all liability in respect of such proceeding for which such
Indemnified Party would be entitled to indemnification hereunder (whether or
not any Indemnified Party is a party thereto).

                 (c)  Contribution.  If the indemnification provided for in
this Section 10 is unavailable to an Indemnified Party or is insufficient to
hold such Indemnified Party harmless for any Claims in respect of which this
would otherwise apply by its terms, then Lessee, in lieu of indemnifying such
Indemnified Party, to the fullest extent lawful shall have a joint and several
obligation to contribute to the amount paid or payable by such Indemnified
Party as a result of such Claims, in such proportion as is appropriate to
reflect the relative fault of Lessee, on the one hand, and such Indemnified
Party, on the other hand, in connection with the actions, statements or
omissions that resulted in such Claims as well as any other relevant equitable
considerations.  The relative fault of Lessee, on the one hand, and such
Indemnified Party, on the other hand, shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, has been taken by, or relates to information supplied
by, Lessee or such Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent any such
action, statement or omission.  The amount paid or payable by a party as a
result of any Claims shall be deemed to include any legal or other fees or
expenses incurred by such party in connection with any proceeding, to the
extent such party would have been indemnified for such expenses if the
indemnification provided for in Section 10(a) or 10(b) was available to such
party.

                 The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 10(c) were determined by pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding
paragraph.  No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.  The indemnity, contribution and expense reimbursement
obligations under this Section 10(c) shall be in addition to any liability
Lessee may otherwise have; provided that any excess payment made by Lessee
shall be refunded to Lessee by the Indemnified Party receiving such excess
payment.
