          SECTION 8. TAXES AND INDEMNITIES.

          8.1 TAXES.

               (a) Each of the parties hereto shall act in good faith and
          cooperate with one another to ensure that the amount of Taxes which
          might arise as a result of this Agreement, any of the other Purchase
          Documents, or the performance hereof or thereof are minimized. Seller
          shall pay (or cause to be paid) in a timely and proper manner, and
          shall indemnify Buyer and its affiliates, successors and assigns
          (within ten Business Days after receipt of written demand therefor) on
          an after tax basis for, all Taxes required by any applicable law (or
          any administrative or judicial interpretation thereof) to be paid in
          connection with the Delivery, and Seller shall prepare and file (or
          cause to be prepared and filed) in a timely and proper manner all
          reports, returns or other documents required by any applicable law (or
          any administrative or judicial interpretation thereof) to be filed
          with respect to such Taxes. Notwithstanding the foregoing, Seller
          shall not have any liability pursuant to this Agreement for, and shall
          not be obligated to indemnify Buyer pursuant to this Agreement against
          any Taxes which: (i) are in the nature of property or ad valorem taxes
          not imposed on the basis of the sale of the Engines and are imposed
          for periods after the Delivery, (ii) are imposed upon the use of the
          Engines subsequent to the sale of the Engines, (iii) are attributable
          to any financing obtained by Buyer for the acquisition of the Engines
          or the recordation or provision of any security interest therefor and
          are imposed for periods after the Delivery, (iv) are attributable to
          any event or occurrence or which otherwise accrues subsequent to the
          sale of the Engines, (v) would not have been imposed but for the form
          of the organization, capitalization, location of the businesses of or
          the conduct of the business activities (other than the activities
          contemplated by this Agreement) or ownership of properties by the
          Buyer in the jurisdiction of the taxing authority imposing such Taxes,
          or (vi) any Lessor Taxes (as defined in the CTA). For the avoidance of
          doubt, (A) nothing contained in this Agreement shall modify or
          otherwise affect any liability for Taxes that Seller may have in its
          capacity as Lessee pursuant to the CTA or the Lease, and (B) in no
          event shall the Buyer be able to recover by way of indemnity the same
          Tax under both this Agreement and the CTA or the Lease.

               (b) The parties hereto expressly agree that the provisions of
          Sections 5.9 and 5.10 of the CTA shall apply MUTATIS MUTANDIS in
          respect of any Taxes and indemnification provided for under this
          Section 8.1.

          8.2 INDEMNITIES.

               (a) Except as provided in Section 8.2(b) below, Seller agrees to
          assume liability for and to indemnify Buyer or any of its officers,
          employees or agents (the "Indemnitees") (other than solely in its
          capacity as a manufacturer of the Engine) against and agrees to pay on
          demand any and all Losses (as defined in the Lease) which Buyer may
          suffer or incur at any time, whether directly or indirectly, arising
          out of, related to or in any way connected with:

                                       10
<Page>

                    (i) the purchase hereunder, ownership, maintenance, repair,
               possession, import, export, registration, storage, modification,
               leasing, insurance, inspection, testing, design, sub-leasing,
               use, condition or other matters relating to the Engines or any
               part thereof (regardless of whether such Losses are based on
               strict liability in tort, any act or omission, including the
               negligence, of any Indemnitee, or otherwise); or

                    (ii) the design of any article or material in the any Engine
               or any Part or its operation, including any defect in design and
               regardless of whether it is discoverable, and any infringement of
               patent, copyright, trademark, design or other proprietary right
               claimed by any Person or a breach of any obligation of
               confidentiality claimed to be owed to any Person.

               (b) Seller is not required to indemnify any particular Indemnitee
          under Section 8.2(a) (without, however, limiting Seller's obligations
          as lessee under the Lease), to the extent a particular Loss:

               (i)   arises out of any act, omission, event or circumstance
                     occurring after Delivery;

               (ii)  is caused by the gross negligence or wilful misconduct of
                     that Indemnitee;

               (iii) is the result of failure by Buyer to comply with any of its
                     express obligations under this Agreement (unless such
                     failure is caused by failure by Seller to comply with any
                     of its express obligations under this Agreement) or any
                     representation or warranty given by Buyer not being true
                     and correct;

               (iv)  is related to any Taxes;

               (v)   constitutes ordinary and usual operating or overhead
                     expenses of such Indemnitee (other than where such expense
                     is caused by the occurrence of any breach by Seller of its
                     obligations under this Agreement);

               (vi)  is a Loss which Buyer and Seller have agreed in writing is
                     to be excluded; or

               (vii) a Loss relating to, resulting from, arising out of or in
                     connection with a "prohibited transaction" within the
                     meaning of Section 406 of ERISA (as defined in the Lease)
                     or Section 4975(c)(1) of the Internal Revenue Code of 1986
                     resulting from the direct or indirect use of assets or any
                     ERISA Plan to acquire or hold Buyer's interest in the
                     Engine or in the case of any transferee of the Buyer, to
                     purchase the Engine from the Buyer.

               (c) The parties hereto expressly agree that the provisions of
          Sections 10(c), (d), (e) and (f) of the CTA shall apply MUTATIS
          MUTANDIS in respect of any Loss and indemnification provided for under
          this Section 8.2.

               the Delivery of such Engine;
