ARTICLE 6 -   DELIVERY

A. INSPECTION AND DEMONSTRATION
   ----------------------------

   1.   The manufacture of the Aircraft by Seller and all materials and parts
        procured by Seller for this purpose may be inspected by Buyer's
        representatives during normal business hours at Seller's Facility. If
        access to any part of Seller's Facility where manufacture is in progress
        or materials or parts are stored is restricted by governmental
        authorities or regulations, Seller shall be allowed a reasonable time to
        make the items available for inspection elsewhere. All inspections by
        Buyer's representative shall be made in accordance with Seller's
        security policies and in such a way that the manufacturing process is
        not hindered or delayed. Seller shall furnish, without charge, office
        space (including desks, telephones, and facsimile equipment) at Seller's
        Facility for a reasonable number of Buyer's representatives. Buyer shall
        notify Seller of the number of representatives requiring office space at
        least thirty days prior to date of arrival .

   2.   Performance and functional data based on ground and flight tests on one
        or more of the early aircraft of the type purchased by Buyer shall be
        the basis for engineering calculations and interpretations to show
        compliance with the Detail Specification excepting the Performance
        Guarantee set forth in Letter Agreement No. 7 which shall be determined
        in accordance with the terms thereof.

   3.   If flight tests are necessary on Aircraft delivered subsequent to
        Buyer's Aircraft No. 1 because of Buyer unique SCNs incorporated in the
        Aircraft, Seller may use one or more of the Aircraft for such flight
        tests and Buyer will accept delivery of such Aircraft without any
        reduction in the Price on account of resulting wear and tear. Buyer
        agrees that any delay resulting from such testing shall be considered an
        Excusable Delay. In no event shall Seller accrue more than ten hours or
        five cycles in performing such flight tests.

   4.   Seller shall perform its standard production ground functional and
        flight test on the Aircraft and the results of such test shall be
        provided to Buyer prior to delivery of such Aircraft. Buyer's
        representatives do not participate in or observe these flight tests.

   5.   Buyer's representatives, at any time prior to technical acceptance of an
        Aircraft (as described in this article), may request correction of parts
        or materials which (i) are not in accordance with the Detail
        Specification or Seller's standard engineering and quality manuals or
        (ii) have material or workmanship which, if the Aircraft were delivered
        and were within the applicable warranty period, would entitle Buyer to
        warranty correction under paragraph A. of Part I of Exhibit C. Buyer
        shall promptly notify Seller after it discovers any such nonconformance.
        Seller shall correct or replace at no-charge to Buyer (unless otherwise
        agreed between Buyer and Seller) all
<PAGE>
 
        such parts, materials or workmanship which are promptly brought to its
        attention and mutually determined to be nonconforming.

B. TECHNICAL ACCEPTANCE
   --------------------

   1.   The Aircraft shall be tendered to Buyer for technical acceptance after
        it has been assembled, completed and tested, but no earlier than seven
        business days prior to the first day of the scheduled month of delivery.
        Seller shall give Buyer ninety days notice of the date on which Seller
        proposes to tender the Aircraft for technical acceptance and delivery.

   2.   At Buyer's request, an acceptance procedure, including ground functional
        and flight test, shall be performed on the Aircraft jointly by Buyer and
        Seller and shall be conducted in accordance with Seller's standard
        procedures. Up to five representatives of Buyer may participate in this
        acceptance procedure and Buyer shall be permitted to flight test the
        Aircraft. Seller shall not be required to provide special
        instrumentation for this acceptance procedure. Seller shall have
        complete control of all flights and shall bear all costs and expenses
        incident thereto. Buyer agrees to complete all inspections and testing
        authorized or permitted under this paragraph before the end of the
        seventh business day after Seller has tendered the Aircraft to Buyer. If
        during the five business day technical acceptance period Buyer
        determines and Seller agrees, which agreement shall not be unreasonably
        withheld, that there is noncompliance with the Detail Specification, the
        seven business day period shall be suspended until (i) Seller corrects
        the noncompliance or (ii) the condition is resolved to the satisfaction
        of Buyer and Seller. During the suspension period Buyer shall continue
        its inspection of areas of the Aircraft unaffected by Seller's efforts
        to correct the noncompliance. Upon completion of (i) or (ii) above,
        Buyer shall have the remainder of the period to complete its acceptance
        (subject to further suspensions as a result of non-compliance with the
        Detail Specification). Buyer shall technically accept the Aircraft if it
        meets the requirements of the Detail Specification.

   3.   Immediately upon completion of the inspection and testing noted above,
        Buyer shall indicate its technical acceptance of an Aircraft by
        execution of Section A of a Certificate of Technical Acceptance and
        Delivery for the Aircraft. Technical acceptance shall not impair the
        warranties set forth in Part I of Exhibit C.

   4.   In the event Buyer fails to complete its technical acceptance within the
        seven business day period, the Aircraft shall be deemed to have been
        technically accepted by Buyer at the end of the seven business day
        period after tender as if Buyer had expressly indicated its technical
        acceptance as noted above.

   5.   Buyer shall have the right to technically accept an Aircraft not in
        compliance with the Detail Specification subject to mutual agreement as
        to the resolution of the non-compliance.
<PAGE>
 
 C.  DELIVERY
     --------
     1.   On the first business day after technical acceptance pursuant to
          paragraph B.3. or B.4. above, but no earlier than the later of the
          issuance of an FAA Certificate of Airworthiness for the Aircraft or
          the first business day of the scheduled month of delivery, Buyer shall
          accept delivery of the Aircraft by endorsement of Section B of a
          Certificate of Technical Acceptance and Delivery for such Aircraft.

2. If Buyer fails to accept delivery of an Aircraft as required in paragraph
   C.1. above, Buyer shall reimburse Seller for all reasonable losses, costs and
   expenses (including, without limitation, taxes, Interest and reasonable
   amounts for transportation, storage, insurance, preservation, preparation and
   protection) sustained by Seller after such date. Seller's acceptance of such
   payments shall not constitute a waiver of its rights to pursue its remedies
   for default or to pursue any other rights it may have at law or otherwise.

3. Upon delivery of and payment for an Aircraft, title to the Aircraft shall
   pass from Seller to Buyer.  Seller shall furnish to Buyer a bill of sale and
   other appropriate documents of title as Buyer may reasonably request.

4. Notwithstanding anything herein to the contrary, in no event shall Buyer be
   required to take delivery of more than two Aircraft per month except for
   Aircraft delayed by Buyer's failure to perform in accordance with the
   Agreement.

ARTICLE 7 -   EXCUSABLE DELAY

A. EXCUSABILITY
   ------------
   1.   Seller shall not be held responsible for nor be deemed to be in default
        of this Agreement because of delays in delivery of an Aircraft, Product
        or Document or delay in the performance of a Service or any other act to
        be performed by Seller under this Agreement (in addition to any such
        delays otherwise permitted herein) due to causes such as an act of God
        or the public enemy; civil war, insurrection or riot; war; natural
        disaster, fire, flood, explosion, earthquake or serious accident;
        epidemic or quarantine restriction; any act of government, government
        priority, allocation regulation or an order affecting material, labor,
        equipment, facilities or completed aircraft; strike, labor trouble
        causing cessation, slowdown or interruption of work; inability after due
        and timely diligence to seasonably procure material, accessories,
        equipment or parts or to obtain qualified labor, delay in transportation
        or, without limitation by enumeration of the foregoing, any other cause
        beyond the control of or not occasioned by the fault or negligence of
        Seller.

   2.   Seller shall promptly notify Buyer of any delay or anticipated delay and
        anticipated duration of any such delay in delivery of an Aircraft.
  
B. LOSS, DESTRUCTION AND DAMAGE
   ----------------------------

   1.   If prior to delivery an Aircraft is lost, destroyed or damaged beyond
        repair, or damaged to the extent that it can be repaired by replacement
        parts to a new condition but cannot be delivered in accordance with the
        delivery schedule set forth in this Agreement, the time reasonably
        required by Seller to furnish a replacement for such Aircraft or to
        accomplish repairs to such Aircraft, is deemed an Excusable Delay.

   2.   If an Aircraft is lost, destroyed or damaged beyond repair, Seller shall
        promptly notify Buyer. As soon as possible Seller shall notify Buyer of
        the earliest date that a replacement aircraft can reasonably be
        delivered, consistent with Seller's other contractual commitments and
        production capabilities. Unless Buyer notifies Seller within one month
        after notice of the replacement aircraft delivery date that Buyer
        desires a replacement aircraft, this Agreement shall be terminated as to
        any such Aircraft and the rights of the parties shall be determined in
        accordance with paragraph D. below. If Buyer timely notifies Seller that
        it wants a replacement aircraft, the parties shall amend this Agreement
        to establish its scheduled month of delivery and shall appropriately
        reschedule progress payments. Notwithstanding the foregoing, nothing
        herein shall obligate Seller to deliver a replacement aircraft if
        manufacture thereof would require the reactivation of the production
        line for the model or series of aircraft purchased hereunder. The Base
        Price of the replacement aircraft shall be the same as that for the
        lost, destroyed or damaged beyond repair Aircraft, except such Base
        Price shall be adjusted in accordance with the article hereof entitled
        PRICE.
<PAGE>
 
 C.   INDEFINITE EXCUSABLE DELAYS
      ---------------------------

      1.   If Seller concludes, based on a continual appraisal of the available
           facts, that the extent of any delay in delivery of any Aircraft by
           reason of an Excusable Delay will exceed twelve months beyond the
           scheduled month of delivery, then Seller shall promptly notify Buyer
           concerning such delay and submit to Buyer a revised scheduled month
           of delivery. Buyer may, by notice to Seller given within one month
           from receipt by Buyer of such notice from Seller, elect then to
           terminate this Agreement as to such delayed Aircraft and the rights
           of the parties shall be determined in accordance with paragraph D.
           below.

      2.   If this Agreement is not terminated as to an Aircraft pursuant to
           paragraph C.1. above, and if during the period of delay Seller
           concludes, based on its appraisal of the available facts, that the
           extent of delay in delivery of any Aircraft by reason of an Excusable
           Delay will exceed six months beyond the revised scheduled month of
           delivery specified in the notice provided pursuant to paragraph C.1.
           above, Seller shall promptly notify Buyer concerning such additional
           delay and submit to Buyer a revised scheduled month of delivery.
           Buyer may, by notice to Seller given within one month from receipt by
           Buyer of such notice from Seller, elect then to terminate this
           Agreement as to such delayed Aircraft and the rights of the parties
           shall be determined in accordance with paragraph D. below.

      3.   Notwithstanding the foregoing, nothing herein shall obligate Seller
           to deliver an aircraft subject to an indefinite excusable delay if
           manufacture thereof would require the reactivation of the production
           line for the model or series of aircraft purchased hereunder.

D.    In the event of termination under paragraphs B. or C. above, Seller
                * * *         * * *          repay to Buyer, without interest,
      the amount of the progress payments which are related to the purchase of
      such terminated Aircraft. Such termination shall discharge all obligations
      and liabilities of the parties with respect to such Aircraft and all
      undelivered Products, Services, Documents or other articles or items
      related to that Aircraft. Any Product, Document or other article or item
      related to that Aircraft which has been delivered shall be returned to
      Seller.

ARTICLE 8 -   BUYER FURNISHED OR DESIGNATED EQUIPMENT

A. BUYER FURNISHED EQUIPMENT
   -------------------------

   1.   Buyer shall furnish the BFE to Seller and Seller shall make appropriate
        provisions for the installation of and shall install BFE. Seller shall
        provide reasonable notice as to the dates (as they may change from time
        to time due to production requirements) Seller needs BFE and its
        respective data. Buyer shall meet Seller's required schedule for receipt
        of such BFE and its respective data. The BFE data shall include a
        written detailed description of the dimensions and weight of such BFE
        and information necessary for its proper storage, installation,
        servicing, maintenance and operation. The BFE data shall not be
        subsequently revised unless agreed to by Seller and, if revised, shall
        be subject to reasonable adjustments in Price and delivery as mutually
        agreed.

   2.   Buyer authorizes Seller to contact and work with Buyer's BFE suppliers
        for purposes of general engineering coordination, expediting shipments,
        adjusting schedules, performing quality control and inspection
        functions, and securing required BFE data. Such efforts by Seller are
        for the purpose of assisting Buyer and its suppliers in meeting BFE
        commitments and shall not relieve Buyer from Buyer's obligations set
        forth in this article. Buyer shall make appropriate arrangements with
        its suppliers for Seller to contact and work with such suppliers as
        described above. At Seller's request, Buyer shall provide technical
        advisors to assist Seller in the installation, calibration, repair or
        replacement, if defective, of any BFE.

   3.   Prior to Seller providing any Documents to BFE suppliers, a proprietary
        information agreement must be in place between Seller and the BFE
        supplier.

B. BUYER DESIGNATED EQUIPMENT
   --------------------------

   1.   Alternatively, upon concurrence by Seller and subject to a handling
        charge equal to ten percent of the price of the BFE, Seller shall
        purchase on behalf of Buyer items of BFE as BDE. Seller shall, in
        accordance with its standard procurement practices, use its diligent
        efforts to obtain BDE at the lowest reasonable cost to Buyer.

   2.   Without waiving Buyer's BFE data obligations defined in paragraph A.
        above, Seller shall on behalf of Buyer use its diligent efforts to
        obtain from the BDE suppliers, by the date required, BFE data to support
        the BDE. At Seller's request, Buyer shall provide technical advisors to
        assist Seller in the installation, calibration, repair or replacement,
        if defective, of any BDE.

C. Seller shall have no obligation to include in its provisioning data for
   Buyer's Aircraft information covering the repair or replacement of BFE or BDE
   items unless Buyer provides such data to Seller in accordance with Seller's
   requirements.  However, if Seller has such information in its existing
   provisioning data files and Seller has a right to disclose that information
   to Buyer, such information will be included in Buyer's Aircraft provisioning
   data at no additional cost to Buyer.
<PAGE>
 
D. PRICE AND PAYMENT
   -----------------
   1.   Buyer agrees to sell and Seller agrees to purchase each item of BFE
        concurrently with its delivery to Seller. A reasonable shipset price for
        the BFE shall be established by Buyer. Buyer and Seller agree that the
        Price of an Aircraft will be increased by the amount of said shipset
        price, without escalation, and such amount shall be included on Seller's
        invoice at time of Aircraft delivery. Seller's payment for the purchase
        of each shipset of BFE from Buyer shall be made at the time of delivery
        of the Aircraft in which the BFE is installed.

   2.   Buyer and Seller agree that the Price of each Aircraft will be increased
        by the price of the BDE installed thereon plus the handling charge and
        such amount shall be included, without escalation, on Seller's invoice
        at time of Aircraft delivery. If Seller purchases any BDE subject to a
        price escalation or price adjustment feature, the Price of each Aircraft
        will be changed to reflect such price escalation or price adjustments.

E. Buyer warrants that the BFE or BDE shall comply with all applicable FAR's and
   U.S. Food and Drug Administration (FDA) sanitation requirements for
   installation and use in the Aircraft at the time of delivery.  Buyer shall be
   responsible for supplying any data and adjusting, calibrating, retesting or
   updating such BFE or BDE and data to the extent necessary to obtain
   applicable FAA and FDA approval and shall bear the resulting expenses.
   Without waiving Buyer's obligation, Seller shall, as an accommodation to
   Buyer, obtain the Certificate of Sanitary Construction on behalf of Buyer.

F. Any delay in an act to be performed by Seller caused by Buyer's failure to
   (i) deliver, or have delivered, BFE, (ii) ensure satisfactory operation of
   the BFE or BDE, (iii) furnish or obtain applicable BFE data, (iv) perform any
   adjusting, calibrating, retesting or updating of BFE or BDE, or (v) furnish
   or obtain any FAA or FDA approvals in compliance with the provisions of this
   article, shall be deemed an Excusable Delay.  Seller shall provide Buyer with
   not less than three days written notice of its intention to treat any such
   delay as an Excusable Delay.  The Price of the Aircraft shall be increased by
   the amount of Seller's additional costs attributable to any such Excusable
   Delay by Buyer, including without limitation, Interest on the unpaid balance
   of such Price, storage, taxes, insurance and the costs of out of sequence
   installations.  However, in the event of such Excusable Delay and without
   waiving any other rights and remedies Seller may have, Seller may (i) elect
   to deliver the Aircraft without the installation of the unapproved, delayed
   or nonconforming BFE or BDE and Seller shall thereupon be relieved of all
   obligations to install such BFE or BDE or (ii) purchase the same or
   substantially equivalent equipment from any other source and install and
   equitably adjust the Price of the Aircraft and any other affected provisions
   of the Agreement to reflect such purchase and associated retesting,
   adjustment and calibration.

G. SUPPORT
   -------

   1.   To properly maintain Seller's production flow and to preserve Seller's
        delivery commitments, Seller reserves the right, if necessary, due to
        equipment shortages or failures, to interchange new items of BFE or BDE
        acquired from or for Buyer with new items of the same part numbers
        acquired from or for other customers of Seller. Such interchange,
        however, shall not result in a delay in delivery of Buyer's Aircraft.
        Used BFE acquired from Buyer or from other customers of Seller will not
        be interchanged.

   2.   For specific BFE which will, in Seller's opinion, be critical to
        Aircraft functional tests and or flights, and whenever other than new
        equipment is furnished to fulfill BFE requirements, Buyer shall, upon
        Seller's request, place in Seller's possession a reasonable number of
        additional units to preclude untimely delays which can be caused by the
        failure of the BFE.

   3.   BFE shall be free and clear of all liens, encumbrances, pledges,
        security interests or rights of others and any used BFE shall be in good
        operating condition and meet Seller's requirements for installation on
        the Aircraft.

   4.   Upon any Spare or interchanged BFE being incorporated or installed on an
        Aircraft, without further act, (i) title to the removed BFE shall vest
        in Buyer, free and clear of all rights of Seller (ii) title to the
        installed BFE shall vest in Seller, and (iii) the installed BFE shall
        become subject to the Agreement and be deemed to be part of that
        Aircraft for all purposes to the same extent as the BFE originally
        supplied for, incorporated or installed in or on the Aircraft. Prior to
        incorporation of the Spare or interchanged BFE into an Aircraft, title
        and risk of loss to any Spare or interchanged BFE shall remain in Buyer.

   5.   Any BFE or BDE delivered to Seller and not installed in an Aircraft
        shall be redelivered to Buyer by Seller at Buyer's expense and in
        accordance with Buyer's instructions upon or after delivery of the last
        Aircraft in as good a condition as when delivered to Seller.

H. If either party shall terminate this Agreement as to an Aircraft pursuant to
   the article entitled EXCUSABLE DELAY, Seller shall, within thirty days of the
   date of the termination notice, advise Buyer of the items of BFE delivered to
   Seller prior to the date of termination notice, that Seller will continue to
   purchase and which items of BFE that Seller will return to Buyer.  In the
   event Seller elects to return BFE, then Seller shall ship the BFE to Buyer at
   Seller's cost, within thirty days of such election and upon shipment Buyer
   shall concurrently repurchase such BFE from Seller.  At the same time Seller
   makes its election with regard to BFE delivered to Seller prior to the notice
   of termination, Seller shall have the right to purchase other items of BFE
   that Buyer has placed on order and which have not been delivered to Seller.
   The price paid for BFE shall be the invoice prices paid by Buyer.

<PAGE>
 
I. Buyer and Seller agree that at the time of Agreement execution, all BFE set
   forth in the Detail Specification and Exhibit A-1 has been designated as
   Seller-Furnished Equipment (SFE).  In the event that Buyer purchases
   additional SCNs that include BFE, such BFE may be provided to Seller under
   the terms of this article.

ARTICLE 9 -   TAXES, CUSTOMS, DUTIES AND LICENSES

A. In addition to all other amounts payable under this Agreement, Buyer shall
   promptly pay to Seller (for purposes of this Article 9, Seller shall include
   any wholly-owned subsidiary of Seller) upon demand any and all taxes,
   including but not limited to sales, use, value added, or other similar taxes
   or fees imposed upon transfers (currently imposed or subsequently enacted)
   and related interest and penalties (collectively referred to in this Article
   9 as "Taxes"), that are imposed by any taxing jurisdiction in connection with
   this Agreement, including but not limited to Taxes occasioned by:

   1.   the sale, lease, delivery, transfer, storage, use, consumption or
        support of any Aircraft, Product, Spare Part, Service or Document;

   2.   the purchase or retention of BFE or BDE;
  
   3.   any act that is expressly requested by Buyer; or

   4.   any act or failure to act by Buyer or other party acting on behalf of
        Buyer in connection with any Aircraft, Product, Spare Part, Service or
        Document.

B. Notwithstanding anything herein to the contrary, Buyer shall not be required
   to pay to Seller:

   1.   Any United States (federal, state or local):
 
        a.   Taxes measured by Seller's net income, capital or both;

        b.   payroll or employment Taxes imposed on Seller;

        c.   Taxes imposed on Seller prior to delivery to Buyer (except to the
             extent that the imposition of such Taxes results from Buyer's
             failure to take in a timely manner any action required of Buyer
             under the provisions of this Agreement, and except Taxes imposed on
             BFE or BDE); or

        d.   any interest or penalties relating to Taxes attributable to (i) any
             delay by Seller in performing any act or (ii) any failure by Seller
             to act, provided that such failure or delay by Seller is not caused
             by Seller's reliance on information provided by Buyer.

   2.   Any Taxes imposed by a jurisdiction outside the United States in
        connection with this Agreement.

C. Seller shall promptly notify Buyer if a claim is made by any jurisdiction
   against Seller for any Taxes described in Paragraph A. of this Article.  If
   reasonably requested by Buyer in writing, Seller, at Buyer's expense, shall
   contest the validity, applicability or amount of such Taxes by actions to
   which Seller and Buyer jointly agree.  If Buyer fails to make such written
   request to Seller, Seller shall promptly pay all Taxes then due and owing and


<PAGE>

 
   Buyer shall promptly reimburse Seller for such Taxes.  Notwithstanding the
   foregoing, Buyer may contest the validity, applicability or amount of such
   Taxes without Seller's participation provided that Buyer delivers to Seller a
   tax indemnification agreement reasonably acceptable to Seller.

D. In addition to all other amounts payable under this Agreement, Buyer shall
   pay Seller upon demand any customs, duties and related brokerage, freight and
   other charges (including related interest and penalties) which are imposed
   upon Seller in connection with the importation to the United States of:

   1.   any BFE or BDE, and

   2.   any item of foreign manufacture to be installed in or applicable to an
        Aircraft, Product, Spare Part, Service or Document as a result of a
        change installed on or incorporated at the request of the Buyer.

ARTICLE 10 -   FEDERAL AVIATION ADMINISTRATION APPROVAL

A. Each Aircraft shall at the time of delivery meet the FAA requirements for
   airworthiness certification and be so certified under all the conditions set
   forth in the Detail Specification.  It is further understood and agreed that,
   except as required by the Detail Specification, each Aircraft need not meet
   FAA requirements for specific operation on Buyer's routes.

B. Subject to the provisions of the article hereof entitled BUYER FURNISHED OR
   DESIGNATED EQUIPMENT if any change, modification or addition to any Aircraft

   governmental regulation or interpretation thereof by a United States
   governmental agency in order to continue the effectiveness of the Type
   Certificate or meet the FAA requirements for airworthiness certification of
   the Aircraft as above provided, such change, addition or modification shall
   be made in the undelivered Aircraft affected.  Seller shall bear the cost of
   complying with FAA airworthiness certification requirements which are
   required to be incorporated in the Aircraft prior to its delivery.  Any delay
   in delivery of an Aircraft by reason of such change, addition or modification
   shall be deemed an Excusable Delay and the scheduled month of delivery of
   such Aircraft shall be adjusted to the extent of such delay.  Seller shall
   provide Buyer with not less than three days written notice of its intention
   to treat any such delay as an Excusable Delay.  Any such change, addition or
   modification effective after Aircraft delivery shall be the sole
   responsibility of Buyer.

        or action which may be made or brought against Buyer, its directors,
        officers, agents, successors or assigns for alleged infringement or
        misappropriation of any United States patent, trademark, copyright or
        trade secret, or any foreign patent, arising out of the purchase,
        possession, use or lease, of a Product or Vendor Part (a Claim),
        provided that:

        a. Buyer gives Seller prompt notice (within ten days after service of
           any such suit or action or 30 days after receipt of any such claim)
           of any Claim and promptly furnishes to Seller copies of all papers
           served upon or received by Buyer relating to such Claim; and,

        b. Buyer cooperates fully with Seller in the defense, including giving
           to Seller all data, documents and information within Buyer's

B. INDEMNIFICATION
   ---------------

   Seller will pay all damages and costs awarded by a court as a result of a
   Claim, together with all interest accruing after entry of judgment or after
   the making of any settlement.  Except for any damages, costs, expenses and
   loss of profit resulting from loss of use, Seller will reimburse Buyer for
   all reasonable expenses incurred by Buyer with respect to a Claim provided
   that Buyer has complied with the conditions of this Article with respect to
   notice and cooperation, or, if Buyer has failed to comply with such
   provisions, if such failure to comply has not materially and adversely
   affected Seller's ability to defend against such Claim.  Seller or Vendor
   shall have the obligation to assume, conduct and control the defense of such
   suit.

C. LOSS OF USE
   -----------

   If a Product or Vendor Part is found pursuant to paragraph 11.A.1. above, to
   infringe any patent, trademark or copyright or to misappropriate any trade
   secret and Buyer is enjoined from using it, Seller will, at its option and at
   its expense, either:

   1.   procure for Buyer the right to use it free of any liability for
        infringement; or

   2.   replace it with a non-infringing substitute which otherwise complies
        with this Agreement and the applicable order.

<PAGE>
 
 D.   The provisions of this Article (i) applies solely to Seller Parts and
      Vendor Parts, (ii) regarding trademarks, copyrights and trade secrets
      apply to and are solely for the benefit of the first purchaser of the
      Aircraft (and to the first operator in the event the Aircraft are leased
      to the first operator or the Aircraft are sold and leased back to Buyer as
      the first operator), and (iii) are Buyer's sole and exclusive remedy with
      respect to a Claim.

ARTICLE 13 -   ASSIGNMENT AND TRANSFER

A. This Agreement shall inure to the benefit of and be binding upon the
   successors and assigns of both parties.  It shall not be assigned in whole or
   in part by either party without the prior written consent of the other party.
   Subject to the provisions of Letter Agreement No. 14, this Agreement may be
   assigned without prejudice to the rights of the other party hereto against
   the assignor, insofar as it relates to any undelivered Aircraft, without such
   consent, by either party through merger, consolidation or reorganization;
   provided, however, that the assignee shall, at the time of assignment without
   such consent, be solvent and have a net worth and a ratio of net worth to
   total debt and liabilities which are not less than that of the assignor.

B. The parties agree that either party may at any time assign its right to
   receive money and, without the other parties' further consent, assign this
   Agreement, (i) in connection with a reorganization, merger or consolidation
   effected to implement a recapitalization or reorganization (or a similar
   transaction) that does not result in a material change to the beneficial
   ownership of such party's voting securities; or (ii) to such party's parent
   or a wholly-owned subsidiary of such party or such party's parent.  Such
   assignment, however, will be without release or impairment of either parties'
   rights.  The assignment shall contain the assignor's  commitment to perform
   and be responsible for any and all of its obligations under this Agreement as
   if the assignment had not been made.

C. Buyer represents that it is purchasing the Aircraft for use and not for
   resale.  However, if Buyer resells, leases or otherwise transfers the
   Aircraft after delivery, it shall obtain from such purchaser, lessee or
   transferee an agreement to be bound by and comply with all relevant
   provisions of this Agreement (including, without limitation, the provisions
   contained in Exhibit C and this article) and upon obtaining such agreement, a
   copy of which shall promptly be delivered by Buyer to Seller, Buyer shall
   have the right to assign to said purchaser, lessee or transferee all the
   rights conferred upon Buyer under this Agreement (including Exhibit C) with
   respect to the Aircraft resold, leased or otherwise transferred.

D. At Buyer's request and expense, Seller shall take any action reasonably
   required for the purpose of causing any Aircraft to be subjected, at or after
   delivery, to an equipment trust, chattel mortgage, conditional sale, lien,
   assignment, lease, or other arrangement for the financing by Buyer of the
   purchase of such Aircraft.  No such action, however, shall subject Seller to
   any liability to which it would not otherwise be subject or modify in any
   respect Seller's contract rights or require Seller to divest itself of title
   to or possession of such Aircraft until delivery of and payment for such
   Aircraft has been made as provided in this Agreement.

ARTICLE 14 -   NOTICES AND REQUESTS

A. Except as otherwise expressly provided in this Agreement, all notices and
   requests required or authorized shall be given in writing.  Notices and
   requests shall be submitted to the addressee noted below by personal
   delivery, electronic transmission with confirmation of receipt or any other
   customary means of communication.  The date upon which any such notice or
   request is received by the addressee shall be deemed to be the effective date
   of such notice or request.  Seller shall be addressed at 3855 Lakewood
   Boulevard, Long Beach, California 90846-0001, Attention:  Contracts
   Department and Buyer shall be addressed at 1800 Phoenix Boulevard, Suite 126,
   Atlanta, Georgia 30349, Attention: Senior Vice President and Chief Financial
   Officer, or to such other person or such other address as the party to
   receive the notice or request shall designate.
<PAGE>
 
ARTICLE 15 -   APPLICABLE LAW, VARIANCES AND WAIVER

A. This Agreement constitutes the final agreement between the parties and
   supersedes all previous negotiations, representations and agreements between
   the parties with respect to the subject matter hereof.  It is the intent of
   the parties to establish this document as the complete and exclusive
   statement of the terms of the agreement.   This Agreement may be amended only
   as provided in the article entitled DETAIL SPECIFICATION CHANGES or  by an
   instrument in writing of even or subsequent date, executed by duly authorized
   representatives of the parties.  Any other purported amendment or
   modification will be null and void.

B. This Agreement shall be construed and performance thereof shall be determined
   according to the laws of the State of California, United States of America,
   excluding its laws regarding conflict or choice of law.  The applicable
   California statute of limitation shall govern this Agreement regardless of
   the forum.  The parties agree to exclude the application of the United
   Nations Convention on Contracts for the International Sale of Goods (1980).

C. The failure of either party to enforce at any time any of the provisions of
   this Agreement or to require at any time performance by the other party of
   any of the provisions of this Agreement shall in no way be construed to be a
   present or future waiver of such provisions.  The express waiver (whether one
   or more times) by either party of any provision, condition or requirement of
   this Agreement shall not constitute a waiver of any future obligation to
   comply with such provision, condition or requirement.
<PAGE>
 
ARTICLE 16 -   NONDISCLOSURE

A. This Agreement contains, and other information provided in connection with
   the transactions contemplated hereby may contain, information which is
   confidential and proprietary to Seller and relates to Seller's research,
   development, trade secrets, products, pricing and business affairs
   (collectively, Confidential Information).  Buyer shall protect the
   Confidential Information with the same degree of care it exercises to protect
   the confidentiality of its own confidential and proprietary information and
   to prevent unauthorized disclosure, use or publication thereof; provided,
   however, that (i) Buyer may disclose Confidential Information to its lenders
   and where required by applicable law, the order of any court or governmental
   agency, or the rules of any applicable securities exchange and (ii) Buyer's
   obligation to protect such information shall be conditioned on Seller clearly
   and conspicuously marking such information as confidential or proprietary.
   Where disclosure of Confidential Information is required pursuant to the
   rules of any applicable securities exchange or pursuant to the direction of
   any governmental authority, Buyer agrees to notify Seller in writing of any
   such disclosure Buyer intends to make as far in advance of the date Buyer
   makes or is required to make the disclosure as is practicable and Buyer shall
   use its reasonable efforts to obtain assurances that confidential treatment
   will be accorded to the information required to be disclosed.  Except as
   permitted herein, Buyer shall not disclose the terms of this Agreement to any
   other party.  The obligation to treat information as Confidential Information
   shall not apply to any information which is publicly available, independently
   developed by Buyer, or obtained rightfully from third parties without a duty
   to keep confidential.

B. Buyer shall not discuss Confidential Information with, or reveal Confidential
   Information to, anyone other than (i) its employees who require knowledge of
   such terms and conditions in the ordinary course and scope of their
   employment; and (ii) agents, consultants and advisors (including legal
   counsel, accountants and management consultants) whose assigned duties
   reasonably require that such disclosure be made.  In the event any disclosure
   is made to the parties identified in the preceding clause (ii), Buyer further
   agrees to inform the recipients of the confidential nature of the information
   and of their obligation to treat such information confidentially pursuant to
   this Agreement.  If disclosure is made to parties identified in the preceding
   clause (ii) in the form of copies of all or part of this Agreement, Buyer
   agrees to attach to the first page of such disclosed materials the following
   legend:

      THIS DOCUMENT CONTAINS TRADE SECRETS AND COMMERCIAL, FINANCIAL AND
      PROPRIETARY INFORMATION WHICH IS PRIVILEGED AND CONFIDENTIAL TO THE

      PERSON, GOVERNMENTAL AGENCY, COMPANY, CORPORATION OR OTHER PARTY EXCEPT AS
      SUCH DISCLOSURE IS REQUIRED BY LAW.

PART I -       WARRANTY AND SERVICE LIFE POLICY 

This Part I contains the terms and conditions applicable to the warranty and 
service life policy.

A.  SELLER'S WARRANTY
    -----------------

    1.   Coverage.  Seller warrants that Products, at the time of delivery by 
         --------
         Seller, shall be free from:

         a.  defects in material and workmanship;

         b.  defects caused by Seller's installation of any article not
             manufactured by Seller in a manner not in accordance with the
             reasonable instructions of the manufacturer;

         c.  defects arising from failure to conform to the Detail
             Specification, except as to portions thereof stated to be estimates
             or approximations or stated to be design objectives; and

         d.  defects inherent in the design, in view of the state of the art as
             of the date of such design, including defects arising from Seller's
             selection of materials or process of manufacture.

    2.   Term. This warranty applies only to defects described in paragraph 1.
         ----
         above which become apparent to Buyer within * * * after installation or
         use of each Product.

    3.   Repair or Replacement. Seller's liability under this warranty for
         ---------------------
         defects described in paragraphs 1.a., 1.b. and 1.c. above is limited,
         at Seller's election, to the repair or replacement (with a similar item
         free from the defect in question) of any defective Product.

    4.   Correction of Design Defects. Seller's liability under this warranty
         ----------------------------
         for defects described in paragraph 1.d. above is limited to correction
         at Seller's expense of all such defects.

    5.   Timely Corrections. Seller, or Buyer with the approval of Seller, shall
         ------------------
         make the repairs, replacements or corrections with reasonable care and
         dispatch in order that the Product involved is not out of service
         longer than necessary.

    6.   Seller's Approval. Within two weeks following receipt of Buyer's notice
         -----------------
         of a defect accompanied by Buyer's request to Seller's Field Service
         Representative at Buyer's main base for permission to make a repair or
         correction, Seller shall notify Buyer of its approval or disapproval of
         the request. If Seller fails to give timely notice, the request shall
         be deemed approved. Approval under this paragraph shall not constitute
         a determination as to the existence of a defect, as described in
         paragraph 1. above.
<PAGE>
 
    7.   Labor Coverage. For defects described in paragraph 1. above, removal
         --------------
         and repair of the defective Product and its reinstallation shall be at
         Seller's expense. When temporary or interim repairs, replacements and
         corrections are accomplished by Buyer and not proposed, requested, or
         approved by Seller, Seller's liability to Buyer for removal and repair
         shall not exceed the cost of furnishing a permanent repair, replacement
         or correction.

    8.   Labor Reimbursement. For defects described in paragraph 1. above,
         -------------------
         Seller shall establish a reasonable estimate for the labor hours
         required for removal and reinstallation and, if performed by Buyer,
         repair or correction of the defective Product and will reimburse Buyer
         for the estimated hours or for Buyer's actual labor hours, whichever is
         less. Buyer's warranty labor rate shall be based upon Buyer's direct
         labor rate per man-hour plus a burden rate of fifty percent, subject to
         annual review and adjustment as mutually agreed. The amount of Buyer's
         warranty labor rate shall not exceed the Douglas Aircraft Company's
         manufacturing direct labor rate plus a burden rate of one hundred
         percent.

    9.   Claims Information. All warranty claims must be submitted in writing to
         ------------------
         Seller's Warranty Administrator at Long Beach, California and shall
         include the following:

    10.  Audit, Notification and Transportation. All warranty claims shall be
         --------------------------------------
         subject to audit by Seller. Seller shall notify Buyer of Seller's
         disposition of each claim. For defects described in paragraph 1. above,
         Seller shall pay all costs of transportation of the defective Product
         returned, to and from Atlanta, Georgia.

    11.  Limitations. Seller shall have no obligation or liability under this
         -----------
         warranty if:

         a.  the Aircraft was operated with any product not specifically
             approved by Seller unless such product was not a cause of the
             defect;

         b.  the Aircraft was not operated or maintained in accordance with the
             AIRCRAFT MANUALS AND DOCUMENTS furnished Buyer pursuant to Part IV
             hereof unless such operation or maintenance was not a cause of the
             defect;

         c.  the Aircraft was not operated under normal airline use unless such
             operation was not a cause of the defect;

         d.  Buyer does not (i) report the defect in writing to Seller's
             Warranty Administrator within one year following such defect
             becoming apparent and (ii) return the defective Product to Seller's
             Facility, unless otherwise approved by Seller, within two months
             following such defect becoming apparent;

         e.  Buyer does not submit reasonable proof to Seller within one year
             after the defect becomes apparent that the defect is due to a
             matter covered within this warranty. Seller shall use reasonable
             efforts to approve or disapprove in writing Buyer's warranty claim
             within two months of receipt; or

         f.  Buyer does not submit its claim for reimbursement within one year
             of the defect becoming apparent to Buyer or within a reasonable
             time period as mutually agreed between Buyer and Seller's Warranty
             Administrator.

    12.  Document Warranty. Seller warrants that at the time of delivery by
         -----------------
         Seller all Documents shall be free from errors. Seller's liability
         under this warranty is limited to replacement during the first twenty-
         four months after delivery of the Document or first use if not used in
         the first twenty-four months with a similar Document or page thereof
         free from the error in question.

B.  Warranties From Other Manufacturers
    -----------------------------------

    1.   Warranties From Other Manufacturers. Seller has made or shall make
         -----------------------------------
         reasonable efforts to obtain favorable warranties from vendors, with
         respect to Vendor Parts. In


<PAGE>
 
         addition, Seller shall make reasonable efforts to extend vendor
         warranties to sixty months. Seller has made or shall make reasonable
         efforts to obtain for Buyer the same warranties or more favorable
         warranties to encompass Buyer's direct purchase of spare parts.

    2.   Vendor Backstop. For those Vendor Parts installed on the Aircraft or
         ---------------
         purchased through Seller, excluding the Engine or the Engine
         manufacturer's parts, in the event of a default by a Vendor in the
         performance of any obligation under any applicable warranty obtained by
         Seller from such Vendor pursuant to paragraph 1. above, or in the event
         of a disclaimer of responsibility by such Vendor for any defect
         constituting a breach of such warranty and upon seasonable notice
         thereof to Seller, the warranties and all other terms and conditions of
         paragraph A. of Part I shall become applicable as if the Vendor Parts
         had been manufactured by Seller except that the warranty period shall
         be the warranty period as set forth herein or the Vendor's warranty,
         whichever is shorter and all transportation costs associated with the
         Vendor Parts shall be borne by Seller. In the event a Vendor does not
         provide a warranty, Seller's Warranty shall apply to such parts.

    3.   Seller's Interface Commitment. At Buyer's request to Seller's Warranty
         -----------------------------
         Administrator, Seller shall, without charge, conduct an investigation
         and analysis of any Interface Problem to determine, if possible, the
         cause of the Interface Problem and to recommend feasible corrective
         action. Buyer shall furnish to Seller all data and information in
         Buyer's possession relevant to the Interface Problem and shall
         cooperate with Seller in the conduct of its investigation and such
         tests as may be required. Seller, at the conclusion of its
         investigation, shall advise Buyer in writing of Seller's opinion as to
         the cause of the Interface Problem and Seller's recommended corrective
         action. Buyer shall have the right to file a warranty claim upon
         determination of the cause of the Interface Problem to the extent that
         warranty coverage is applicable hereunder.

    Covered Component.

<PAGE>
 
    2.   Price. Any part or Covered Component which Seller is required to
         -----

                    N
             where:

             P   =  Price to Buyer;

             C   =  Seller's then current Seller Part sales price;

             T   =  the total time to the nearest month during which the 
                    Covered Component has been used; and

             N   =  * * *      months.

         In the event that C is       * * *      or less, Seller shall provide

<PAGE>
 
PRICE ADJUSTMENTS FOR FLUCTUATIONS IN THE ECONOMY

The Base Price of each Aircraft, after any price adjustments made in accordance
with paragraphs B. and C. of the article entitled PRICE, shall be subject to the
following escalation provisions in order to determine the Price:

A.  Price
    -----

    The Price shall be determined according to the following formula:


             P = AF\\n\\ + E\\n\\

   where:

             P = Price
                    
       AF\\n\\ = Final Adjusted Airframe Price
                    
        E\\n\\ = Final Adjusted Engine Price

B.Final Adjusted Airframe Price

    1.   The Airframe Base Price included in the Base Price contains no
         allowance for inflation subsequent to the period of November 1994
         through March 1995. Accordingly, the Airframe Base Price shall be
         adjusted to determine the Final Adjusted Airframe Price, by use of the
         formula in paragraph 2. below which is based on fluctuations in the
         following labor and material price indexes which are published by the
         United States of America - Department of Labor, Bureau of Labor
         Statistics:

    2.   The formula for the airframe is as follows:
         
              AF\\n\\ =
                         
                     Fb [.75 (ECIn) +.25 (ICn} 
                              ----        ---
                             130.0        123.6
        where:
                         
          AF\\n\\ = The Final Adjusted Airframe Price.
                         
          AF\\b\\ = The Airframe Base Price.

         ECI\\n\\ = The average of the ECI Index values for the fourth through
                    the eighth month (as described in 1.a. above) prior to the
                    original scheduled month of delivery computed to one
                    decimal place (Note: 1.05 rounds to 1.1).
                     
            130.0 = The average of the ECI Index values for November 1994
                    through March 1995 (as described in 1.a. above).
                         

          IC\\n\\ = The average of the IC Index values for the fourth through
                    the eighth month prior to the original scheduled month of
                    delivery computed to one decimal place (Note: 1.05 rounds
                    to 1.1).
                     
            123.6 = The average of the IC Index values for November 1994
                    through March 1995.

3.  Airframe Rounding Rules are as follows:

         Unless otherwise specified, computations shall be made to four decimal
         places (Note: 1.00005 rounds to 1.0001). After final computation, AFn
         shall be rounded to the nearest whole number (Note: 0.5 rounds to l).

    4.   The most recent ECI and IC Index values released by the Bureau of Labor
         Statistics and made available to Seller for the applicable months shall
         be used to determine the ECI\\n\\ and IC\\n\\ values used in the
         calculation of the Final Adjusted Airframe Price. However, the index
         denominators of 130.0 and 123.6 shall not be revised. The Price of the
         Aircraft shall not be adjusted after delivery except as defined in
         paragraph B.5. below.

    5.   In the event any of the index values required to calculate ECI\\n\\ and
         IC\\n\\ have not been released by the Bureau of Labor Statistics and
         made available to Seller, Seller shall use the published value for the
         nearest preceding quarter for the ECI\\n\\ or the

<PAGE>
 
         nearest preceding month for the IC\\n\\ for the purposes of calculating
         the Final Adjusted Airframe Price until such values are subsequently
         published or made available to Seller. Seller shall submit either a
         supplemental invoice or refund the amounts due Buyer as appropriate to
         reflect any increase or decrease in the Final Adjusted Airframe Price
         for the Aircraft from that determined at the time of delivery of such
         Aircraft.

    6.   If the Department of Labor revises the methodology (in contrast to
         benchmark adjustments and any other corrections of previously released
         values) or discontinues any of the indexes referred to in this Exhibit,
         the parties shall select a substitute for the revised or discontinued
         index. The substitute index shall lead in application to the same
         adjustment result, insofar as possible, as would have been achieved by
         continuing to use the original index as it may have fluctuated had it
         not been revised or discontinued. Appropriate revision of the formula
         shall be made to accomplish this result.

    7.   To implement paragraph B.6. above, either party may notify the other
         that a change in the indexes within the meaning of this Exhibit is
         anticipated or has taken place. Seller shall then propose substitute
         indexes and formula revision. Within ninety days from such notification
         or from receipt of data covering the last month of publication of the
         unchanged index series, whichever is later, the parties shall agree on
         substitute indexes and formula revision. If the parties cannot so
         agree, they shall select an arbitrator to decide the substitute index
         required to carry out the intent of paragraph B.6. above, and the
         decision of the arbitrator shall be binding. If, however, the parties
         cannot agree on an arbitrator, an arbitrator shall be selected in
         accordance with the Commercial Arbitration Rules of the American
         Arbitration Association. Adjustment of the Price under this Exhibit and
         payment of invoices computed from the adjusted Price, shall continue
         following any change in the indexes throughout any period of
         negotiation or arbitration. The indexes and formula used when the
         unchanged indexes are not available shall be those proposed by Seller,
         but said payments shall be on a temporary basis and shall be corrected.
         Any required refunds or additional payments shall be made within thirty
         days following agreement between the parties or an arbitration
         decision.

C.  Final Adjusted Engine Price (E\\n\\)
    -----------------------------------

    1.   The Engine Base Price contained in the Base Price of the Aircraft after
         any adjustment made in accordance with paragraphs B. and C. of the
         article entitled PRICE, shall be adjusted in accordance with the
         escalation formula contained in paragraph 2. below to obtain the Final
         Adjusted Engine Price. The Final Adjusted Engine Price, is derived in
         accordance with the formula set forth below which is based on
         fluctuations in the following labor, material and energy price indexes

                     original scheduled month of delivery computed to one
                     decimal place (Note: 1.05 rounds to 1.1).
                         
             130.0 = The average of the ECI Index values for November 1994
                     through March 1995 (as described in 1.a. above).
                         
           IC\\n\\ = The average of the IC Index values for the fourth through

         values) or discontinues any of the indexes referred to in this
         Paragraph C., the parties shall select a substitute for the revised or
         discontinued index. The substitute index shall lead in application to
         the same adjustment result, insofar as possible, as would have been
         achieved by continuing to use the original index as it may have
         fluctuated had it not been revised or discontinued. Appropriate
         revision of the formula shall be made to accomplish this result.

ValuJet Airlines, Inc.
1800 Phoenix Boulevard, Suite 126
Atlanta, Georgia  30349

Simultaneously herewith ValuJet Airlines, Inc. (Buyer) and McDonnell Douglas
Corporation (Seller) have entered into Purchase Agreement No. DAC 95-40-D (the
Agreement) which Agreement covers the manufacture and sale by Seller and the
purchase by Buyer of MD-95-30 aircraft (the Aircraft). It is agreed that upon
execution by both parties hereto, this Letter Agreement shall constitute a part
of said Agreement.

1. Interim Lift
   ------------
  
   For Buyer's requirement for interim lift between January 1, 1997 and the
   delivery of the first MD-95-30, Seller shall provide interim lift support
   with DC-9 Series 20, 30, 40, or 50 or MD-80 Series 81, 82, 83, 87 or 88
   aircraft, all of which shall be Stage 3, on the following terms and
   conditions:

   A.     Buyer and Seller agree that Buyer's requirement for interim lift
          aircraft from Seller is 15 aircraft per year in each of 1997 and 1998,
          and for 1999 the net difference between 15 and the number of MD-95-30s
          delivered in 1999. Seller shall supply interim lift aircraft at no
          more than two per month. Except as otherwise mutually agreed, no more
          than 4 of the interim lift aircraft supplied by Seller in 1997, 5 in
          1998 and 5 in 1999 shall be MD-80s. Prior to committing to an interim
          lift MD-80 for Buyer, Seller shall advise Buyer of its intent and
          Buyer shall have the option to advise Seller that it does not want
          such MD-80, in which event Seller's obligation to provide interim lift
          aircraft shall be reduced by one (up to a maximum reduction in any
          year of the number of MD-80s Seller is permitted to supply in such
          year). Buyer shall have two business days from receipt of notice from
          Seller in which to exercise its option to reject an MD-80.

   B.     Seller commits to provide the interim lift aircraft to Buyer under
          lease as follows:

          1)    For hushkitted DC-9s, the aircraft shall be delivered to Buyer 
                         * * * shall be leased to Buyer for * * * per month,
                           paid monthly in advance. * * *

          2)    For used MD-80s, the aircraft shall be delivered to Buyer * * *
                      and shall be leased to Buyer for a monthly in advance
                      rental factor equal to
<PAGE>
 
                   * * * per month. Seller's Total Capitalized Cost shall mean
                its total purchase price paid for the aircraft plus all out of
                pocket costs and expenses incurred by Seller to purchase the
                aircraft and lease it to Buyer, including without limitation
                brokers' fees, costs to reconfigure the aircraft and interest
                capitalized at 30-day Libor plus * * * (but not including any
                interest accrued in any month as a result of Seller not being
                able to deliver the aircraft to Buyer because Seller has already
                delivered two aircraft to Buyer in such month and not including
                any interest accrued during any period that the aircraft is
                leased by Seller to an operator other than Buyer).

   C.     Seller shall have the option to purchase or arrange a lease in to
          Seller on the interim aircraft, subject to coordination with Buyer.

   D.     The minimum lease term of any interim lift aircraft shall be * * *
          years or to delivery of a corresponding MD-95-30, at Seller's option,
          determined at time of lease inception. The corresponding MD-95-30
          shall be determined on a one-for-one basis on a first in, first out
          basis (e.g., the first MD-95-30 delivered will cause the first interim
          lift aircraft lease which Seller has elected to terminate prior to * *
          * years to terminate or the first aircraft sold and financed under G.
          below, whichever was closed first, to be repaid or resold, and upon
          delivery of the second MD-95-30 the next interim lift aircraft under
          lease which Seller has elected to terminate prior to * * * years or
          aircraft financed under G. below, whichever occurred first, shall
          terminate or be repaid or resold, as the case may be). The lease shall
          be a net lease with all insurance, taxes, and other expenses
          associated with the use, possession and return of the aircraft to be
          paid by Buyer. Leased aircraft must be operated at all times by Buyer
          and shall be operated so as to permit MACRS depreciation. Seller shall
          have section 1110 protection. Seller shall have the right to assign
          any lease and Buyer will cooperate with Seller on any Seller arranged
          * * *                    judgment. Subject to the terms specifically
          described herein, the lease shall be documented in a form reasonably
          satisfactory to both parties.

   E.     The aircraft shall be returned at the end of the lease term in the
          same condition as delivered (normal wear and tear excepted) * * * and
          with a fresh "C" check, registered with the FAA, and capable of
          immediate service in the U.S. under Buyer's maintenance program (it
          being understood that the detailed return conditions will be
          negotiated in the lease documentation).
<PAGE>
 
                                  *    *    *









   H. In the case where Seller has purchased DC-9 and MD-80 aircraft and leased
      the aircraft to Buyer, Buyer shall have a one-time purchase option at the
      end of the lease term equal to the greater of fair market value or the
      stipulated loss value (as set forth by Seller in the lease). * * *
<PAGE>
 
   I. In the event Buyer is able to obtain more than * * * aircraft from other
      sources in 1997, 1998, or 1999, then Seller's obligation to provide and
      Buyer's obligation to take interim lift aircraft in that year shall be
      reduced one-for-one for the amount in excess of * * * aircraft unless
      Seller has already arranged for interim lift aircraft in which event Buyer
      shall remain obligated to purchase or lease, as the case may be, the
      interim lift. In the event Seller provides interim lift earlier to Buyer,
      or in amounts greater than set forth in paragraph A of this Letter
      Agreement, and Buyer agrees to take the earlier aircraft, Seller's future
      commitment will be reduced by such earlier-provided lift. If Buyer obtains
      less than * * * aircraft from other sources in 1997, 1998 or 1999 because
      Buyer determines that its need for aircraft is less than * * * in any of
      such years                * * *             Seller's obligation to provide
      15 interim lift aircraft will be reduced by one for each aircraft less
      than * * * obtained by Buyer from other sources.

   J. Seller will provide technical assistance to Buyer at rates to be
      negotiated with respect to inspection and ferrying of Buyer interim lift
      aircraft.

   K. Buyer agrees its targeted fleet growth is * * * aircraft per year at a
      rate of * * * aircraft per month. Buyer and Seller agree to fill this
      demand on a first come, first served basis, whichever party shall first
      obtain the interim lift, i.e., if Seller commits to interim lift aircraft
      for Buyer prior to Buyer notifying Seller that it has already secured or
      does not require such interim lift, Buyer shall be required to purchase or
      lease such interim lift aircraft under the terms described above. Buyer
      shall not be required to take more than two aircraft per month from
      Seller.

   L. Seller's obligation to provide any interim lift shall be contingent upon:

      1)  Buyer not being in material default under any of the following
          agreements:

          a) The Agreement;

          b) any other agreement between MDC or MDFC or their affiliates and 
             Buyer; and

          c) any Buyer financing           *  *  * 

2. Bridge Financing
   ----------------

   Seller will offer Buyer bridge financing (the "Bridge Financing") between
   December 1, 1995 and the first scheduled (as such schedule may be revised)
   MD-95-30 delivery under the Agreement on the following terms and conditions:
<PAGE>
 
   A. Bridge Financing will be available for Buyer's purchase of used DC-9s and
      MD-80s.

   B. The Bridge Financing shall be a revolving line of credit limited to a
      maximum outstanding at any one time of    *  *  *

   C. Seller will agree to purchase each aircraft on behalf of Buyer at a price
      not to exceed fair market value.

   D. Buyer will pay a fee to Seller equal to * * * of any amount drawn down
      under the Bridge Financing, payable at the time of each drawdown.

   E. Buyer will pay a downpayment to Seller on each aircraft in an amount equal
      to * * *  of the purchase price paid by Seller for the aircraft.

   F. Simultaneous with Seller's entry into an agreement to purchase any
      aircraft, Buyer will enter into a purchase agreement with Seller to
      purchase such aircraft from Seller no later than * * * after Seller's
      purchase of the aircraft for an amount equal to Seller's purchase price
      net of the downpayment, plus escalation thereon at the rate of * * * over
      30-day Libor (per annum calculated monthly).       * * *

   G. The aircraft will be registered in the U.S. with the FAA in the name of
      Seller until they are purchased by Buyer.

   H. Buyer will maintain on any aircraft subject to the Bridge Financing, at
      its expense and for the benefit of Seller, all risk and liability
      insurance in amounts and coverage reasonably acceptable to Seller.

   I. Buyer will be responsible for all fees and taxes, including without
      limitation any and all sales or property taxes incurred by Seller in
      connection with its purchase, ownership or sale of the aircraft.

                                   *   *   *

   K. Any Bridge Financing will be assignable by Seller to another lender, but
      any assignment shall not increase the financing available under paragraph
      B.

   L. Seller's obligation to provide any Bridge Financing shall be contingent
      upon the following additional terms and conditions:
<PAGE>
 
      1)  Buyer not being in material default under any of the following
          agreements.

          a) The Agreement;

          b) any other agreement between MDC or MDFC or their affiliates and 
             Buyer; and

          c) any Buyer financing for which Seller has provided a guarantee.
      2)  Bridge Financing documentation reasonably satisfactory to Seller.

           -----------------------

           Mission payload, block fuel and block time guarantees in Paragraph
           1.6 are based upon the assumed Operator's Empty Weight (OEW) as shown
           below. This weight is the sum of the guaranteed Manufacturer's Empty
           Weight (MEW), as provided in Paragraph 2.1, plus assumed operator's
           items as shown below:

4.2        OTHER GUARANTEE CONDITIONS
           --------------------------

4.2.1      All takeoff and landing performance shall be based on operation from
           hard-surface, level, dry runways with no wind and without the use of
           thrust reversers, and the Aircraft's CG location not more forward
           than 5.9% MAC. The engine will not be supplying bleed air for cabin
           air conditioning or anti-ice during takeoff, second segment climb,
           final segment climb, approach climb, and landing climb unless
           otherwise noted. Bleed air shall be limited to one (1) air
           conditioning pack per operating engine when it is supplied for final
           segment climb, enroute climb, approach climb, and landing climb.

4.2.2      The Aircraft shall not be restricted by loading considerations on the
           runway, taxiway, or pier at La Guardia airport.

4.2.3      All performance data are based upon ICAO International Standard
           Atmosphere 1964. All altitudes are pressure altitudes.

           deck. New engines are those with up to 50 hours total operating time.

           The installed engine thrust and fuel flow data include allowances for
           normal aircraft bleed air and horsepower extraction. Normal bleed air
           is defined as that required to operate the airplane environmental
           control system when the actuation switches on the air conditioning
           panel in the flight deck are in the "normal" position. Normal
           horsepower extraction is defined as the engine shaft horsepower
           extraction required to operate the aircraft accessory systems during
           each phase of flight, i.e. takeoff, climb, cruise, descent, and
           landing.

4.2.7      No allowances are made for warm-up, taxi, takeoff, maneuver, climb,
           wind, ice protection or descent unless otherwise specified.

4.2.8      In the event of any change to any law, governmental regulation or
           requirement, or interpretation thereof ("rule change") by any
           governmental agency made subsequent to the date of execution of this
           Agreement, and such rule change affects the Aircraft configuration
           and/or performance in order to permit Seller to obtain certification,
           the guarantees contained herein shall be appropriately modified to
           reflect the effect of the rule change. Notwithstanding the above,
           Seller shall use reasonable efforts to maintain the performance
           values guaranteed herein in the event of such rule change.

4.2.9      The Federal Aviation Regulations (FAR) referred to in Paragraph 1.0
           hereof are defined in the MD-95-30 certification basis as given in
           Paragraph 02-11 of the Detail Specification DS 9530A, dated January
           5, 1995.

9.0        REMEDIES
           --------


9.1        *    *    *

 
<PAGE>
 
Buyer agrees to accept Aircraft not complying with the guarantees set forth
herein provided that such non-compliance does not substantially impair the
profit-making potential, operation or performance of the Aircraft.    In the
event it is demonstrated that the Aircraft do not comply with the above
guarantees, Buyer agrees to allow Seller a reasonable period of time, but not to
exceed twenty-four months after delivery of the first Aircraft, to take the
action necessary to enable compliance with the guarantee.            *   *   *

actions to comply with the guarantees herein may include, but shall not be
limited to, the development of hardware, systems and procedural changes to or
for the Aircraft.  Seller shall offer these to Buyer at no cost and may do so
before or after delivery of the Aircraft. If such recommended action will not
have a material adverse cost impact on Buyer and Buyer nonetheless declines to
accept such recommended reasonable changes to ensure compliance with a
guarantee, such guarantee level shall be adjusted to reflect the loss of the
performance benefits Seller estimates such actions would have produced.  In
those instances where a non-compliance to a guarantee does not, due to other
compensating capabilities of the Aircraft, adversely affect the overall
operational suitability of the Aircraft in Buyer's operation, Buyer and Seller
shall mutually agree on a resolution to such non-compliance.

The guarantees  herein are by this reference made a part of the Detail
Specification.

If the foregoing correctly sets forth our understanding, please execute this

ValuJet Airlines, Inc.
1800 Phoenix Boulevard, Suite 126
Atlanta, Georgia  30349


Simultaneously herewith ValuJet Airlines, Inc. (Buyer) and McDonnell Douglas
Corporation (Seller) have entered into Purchase Agreement No. DAC 95-40-D (the
Agreement) which Agreement covers the manufacture and sale by Seller and the
purchase by Buyer of MD-95-30 aircraft (the Aircraft).  It is agreed that upon
execution by both parties hereto, this Letter Agreement shall constitute a part
of said Agreement.

MECHANICAL DISPATCH RELIABILITY AND COMPLETION GUARANTEE
- --------------------------------------------------------

The highest rates of Mechanical Dispatch Reliability and Completion can only be
attained when both Seller and Buyer work as partners to have a high quality
designed and manufactured aircraft, significant factory support, appropriate
spare parts stock, fully trained maintenance and operations crews and other
appropriate resources. Based on this concept and subject to the conditions set
forth below, the following guarantees are made with respect to the Aircraft:

Dispatch Reliability - Percentage of revenue flights with less than 15 minute
mechanical delays:

- ------------------------------------------------------------------------------ 
   First 3 Months*      Next 9 Months*      Years 2 and 3*     Years 4 - 10*
- ------------------------------------------------------------------------------
      * * *                 * * *               * * *              * * * 
- ------------------------------------------------------------------------------


Completion Factor - Percentage of flights completed within 24 hours of scheduled
arrival:
 
- ------------------------------------------------------------------------------ 
   First 3 Months*      Next 9 Months*      Years 2 and 3*     Years 4 - 10*
- ------------------------------------------------------------------------------
      * * *                 * * *               * * *              * * * 
- ------------------------------------------------------------------------------
<PAGE>
 
    * Calculated from the first day of the month immediately following the month
    of delivery by Seller to Buyer of the first Aircraft (the "Commencement
    Date").

    Buyer and Seller agree that because Seller is not making any guarantee
    commitment for the first three months following delivery to Buyer of the
    first Aircraft, the first "annual" calculation with respect to dispatch
    reliability and mission completion shall be based on the nine-month period
    commencing on the three-month anniversary of the Commencement Date.
    Calculations shall be made on a fleet basis, not on an individual Aircraft
    basis.

A.  Dispatch Reliability is defined as an average (expressed as a percentage),
    which shall be calculated by application of the following formula:.
           
      Dispatch Reliability = 100 x | 1 - (Total Chargeable Mechanical Delays)
                                   |    (----------------------------------)
                                   |          (Total Scheduled Departures)


    A Chargeable Mechanical Delay is defined as a delay in excess of 15 minutes
    beyond the scheduled revenue departure time, or a cancellation, caused by
    mechanical malfunction of the Aircraft.

    Mission Completion is defined as an annual average (expressed as a
    percentage), which shall be calculated by application of the following
    formula:

        Mission Completion = 100 x | (Total Revenue Flights Completed)
                                   | (-------------------------------)
                                   | (Total Revenue Flights Scheduled)

    A flight will not be included in Total Revenue Flights Completed in the
    event of a failure to complete a scheduled Buyer revenue flight within a 24-
    hour time period commencing from the scheduled revenue flight arrival time
    caused by mechanical malfunction of the Aircraft.

    Buyer shall report to Seller on a monthly interval, such information and
    data as Seller would reasonably need to maintain a reliability data base to
    track compliance to the Dispatch Reliability and Mission Completion
    guarantees. Seller will provide a program status report to the Buyer every
    six months or as mutually agreed.

B.  Delay and cancellation mechanical classification will be determined pursuant
    to Buyer ground rules with the concurrence of Seller's Field Service
    Representative on chargeable delays and cancellations. Delays and
    cancellations not jointly concurred on will be reviewed and dispositioned by
    mutual agreement on a quarterly basis by Seller's Vice-President and General
    Manager of Product Support, Seller's MD-95 Chief Engineer and Buyer's Vice
    President of Engineering and Maintenance.
<PAGE>
 
C.  Reasonable spare Aircraft as mutually agreed by Seller and Buyer will be
    incorporated into Buyer's scheduling plan.

D.  An appropriate stock of spare parts will be maintained by Buyer to meet
    Dispatch Reliability and Mission Completion guarantees. If delays are caused
    by Seller's inability to deliver spare parts pursuant to the shipment
    provisions of Part III to Exhibit C to the Agreement, then this stocking
    requirement will be waived in the determination of cause.

E.  If the calculated Dispatch Reliability or Mission Completion guarantee has
    not been achieved for three consecutive months, Seller and Buyer will
    jointly agree to review the joint reliability data base to identify areas
    needing improvement and to determine a course of action. Seller and Buyer
    will identify and assign full-time MD-95 reliability focus points and
    provide the necessary personnel until the guarantees are being met. In
    addition, Seller will work with Buyer to provide the following support in
    the event either the Dispatch Reliability or Mission Completion guarantees
    are not met, in addition to the remedies offered under paragraph F. of this
    Agreement.

    a.   Review of data provided by Buyer related to parts, material,
         components, accessories and equipment incorporated within and on, and
         used in conjunction with, the Aircraft, and furnish technical

2. DELIVERY DELAYS (AIRCRAFT)
   --------------------------

   A.   In the event that one or more Aircraft is delayed (beyond its scheduled
        month of delivery as defined in Article 6, Paragraph C.) and the
        delivery delay is not an Excusable Delay (an "Unexcused Delay"), Seller
        shall notify Buyer of such Unexcused Delay at the time the delay becomes
        apparent. For the purposes of this Section 2, an "Unexcused Delay" shall
        not include          * * *       Excusable Delays and the term
        "scheduled month of delivery" shall mean the scheduled month of delivery
        as adjusted for * * * Excusable Delays.

   B.   Seller shall advise Buyer eight months prior to the first day of the
        scheduled month of delivery of each Aircraft as to the delivery status
        of the Aircraft. At this time Seller shall use its reasonable efforts to
        advise Buyer of any delivery delay. If at this time Seller believes
        there would be an Unexcused Delay, Seller shall provide Buyer a revised
        scheduled month of delivery. Subject to the limitations set forth in
        Section 3 below, any delivery in or prior to the revised scheduled month
        of delivery shall not be deemed an Unexcused Delay and no damages shall
        be paid to Buyer for such delay.

   C.   In the event that Seller notifies Buyer between the first day of the
        eighth month and the last day of the sixth month prior to the scheduled
        month of delivery or the revised scheduled month of delivery (as
        described in paragraph B above) that Seller reasonably believes that
        there will be an Unexcused Delay in delivery of an Aircraft, Seller
        shall pay Buyer liquidated damages in the amount of $1,000 per day.

   D.   In the event that Seller notifies Buyer between the first day of the
        fifth month and the last day of the fourth month prior to the scheduled
        month of delivery or the revised scheduled month of delivery (as defined
        in paragraph B above or as revised in C. above) that Seller reasonably
        believes that there will be an Unexcused Delay in delivery of an
        Aircraft, Seller shall pay Buyer liquidated damages in the amount of
        $2,500 per day.

   E.   In the event that Seller notifies Buyer less than three months prior to
        the scheduled month of delivery or the revised scheduled month of
        delivery (as defined in paragraph B above or as revised in C or D above)
        that Seller reasonably believes that there will be an Unexcused Delay in
        delivery of an Aircraft, Seller shall pay Buyer liquidated damages in
        the amount of $5,000 per day.
<PAGE>
 
   F.   Payment of liquidated damages as set forth above shall begin thirty days
        after the last day of the scheduled month of delivery or revised
        scheduled month of delivery (as defined in paragraph B above) and end on
        the day that the Certificate of Airworthiness is issued for the delayed
        Aircraft up to a maximum of $5,000 per day and a total amount of
        $100,000 per Aircraft. Liquidated damages shall be paid in the form of a
        credit memorandum available at delivery of the delayed Aircraft to be
        used for the purchase of Seller proprietary goods and services or to
        reduce the final invoice price of the delayed Aircraft as determined by
        Buyer.

   G.   In the event of any delay in delivery of an Aircraft (except (i) a
        replacement aircraft purchased by Buyer in accordance with Article 7,
        Paragraph B.2., (ii) a delay caused by Buyer's default or (iii) a delay
        requested by Buyer) beyond the original scheduled month of delivery as
        defined in Article 6, Paragraph C, Seller shall use such original
        scheduled month of delivery for the purpose of computing the escalation
        to be included in the final Aircraft invoice price.



                                  *    *    *



4. LIQUIDATED DAMAGES
   ------------------

   The parties have agreed upon the amount to be paid hereunder, as an endeavor
   to make a reasonable estimate of probable actual loss, because it would be
   impracticable or extremely difficult to determine with exactness the actual
   loss resulting from an inexcusable delay in delivery of an Aircraft as
   scheduled.  Therefore, Buyer and Seller hereby fix said sum as liquidated
   damages and not as a penalty.  Except as to Unexcused Delays exceeding one
   year, for which damages and claims have not been liquidated hereunder, this
   amount shall be in complete and total satisfaction for any and all claims
   Buyer may have against Seller as a result of such delay, whether such claims
   are for direct, indirect, incidental or consequential damages.

CHANGE OF CONTROL AND FINAL ASSEMBLY
- ------------------------------------

1. In the event of a Change in Control of Buyer (as defined below), Seller shall
have the right to terminate the Agreement.

   For the purposes of this Letter Agreement, "Change in Control" shall mean the
first to occur of the following events:

A.   The date of the first public announcement that any person or entity,
     together with all Affiliates and Associates (as such capitalized terms are
     defined in Rule 12B-2 promulgated under the Securities Exchange Act of
     1934, as amended [the "Exchange Act"]) of such person or entity, shall have
     become the Beneficial Owner (as defined in Rule 13d-3 promulgated under the
     Exchange Act) of voting securities of the Buyer  representing 50% or more
     of the voting power of the Buyer (a "50% Stockholder"); provided, however
                                                             --------         
     that the terms "person" and "entity" as used in this clause (A.) shall not
     include (1) the Buyer or any of its subsidiaries, (2) any employee benefit
     plan of the Buyer or any of its subsidiaries including the Buyer's Employee
     Stock Ownership Plan, (3) any entity holding voting securities of the Buyer
     for or pursuant to the terms of any such plan, or (4) Messrs. Priddy,
     Jordan, Gallagher and Flynn, individually or as a group; or

B.   A reorganization, merger or consolidation of the Buyer (other than a
     reorganization, merger or consolidation the sole purpose of which is to
     change the Buyer's domicile solely within the United States or a
     reorganization, merger or consolidation effected to implement a
     recapitalization or reincorporation of the Buyer (or a similar transaction)
     that does not result in a material change in beneficial ownership of the
     Buyer's voting securities) the consummation of which results in the
     outstanding securities of any class of the Company's securities being
     exchanged for or converted into cash, property and/or a different kind of
     securities.
<PAGE>
 
C.   Approval by the Buyer's stockholders of a plan of complete liquidation of
     the Buyer or an agreement for the sale or other disposition by the Buyer of
     all or substantially all of the Buyer's assets.

Notwithstanding the foregoing provisions, a Change in Control shall not be
deemed to have occurred if the "person" described in the preceding portion of
this Letter Agreement is an underwriter or underwriting syndicate that has
acquired the ownership of 50% or more of the combined voting power of the
Buyer's then outstanding voting securities solely in connection with a public
