All terms used but not defined in this Letter Agreement have the same meaning as in the Purchase Agreement. In accommodation of Customer's expressed desires for aircraft delivery flexibility, Customer and Boeing have reached agreement regarding certain modifications to the Agreement as set forth below: 2. Purchase Right Aircraft Delivery Timing Boeing offers Customer twenty (20) model 737-8EH purchase right aircraft; with delivery of all such purchase right aircraft to occur not later than 31 December 2010 at a rate of not more than five (5) per year, with firm purchase exercise requirements as follows: Number Exercise Number Exercise of aircraft Date of Aircraft Date - ----------- -------- ----------- -------- 4 June 2007 3 June 2005 5 June 2008 4 June 2006 4 June 2009 P.A. No. 2910 SA-1 GOT Letter Agreement NO. 6-1162-DME-0706 Page 2 GOL Transportes Aereos SA All purchase right aircraft are offered on a subject-to-availability-of-position (STAP) basis, and will retain the same Model 737-8EH configuration and detail specification as that described in Exhibit A to the Purchase Agreement, with the exception of any detail special feature changes as may be mutually agreed. With the firm exercise of each purchase right, Boeing offers Customer the ability to add a one-for-one additional purchase right aircraft, to a maximum of six (6) such additional purchase right aircraft, with any such additional purchase right aircraft to also be STAP and exercised not later than 01 June 2009 for delivery not later than 31 December 2010. Should Customer choose not to exercise some or all of the offered purchase right aircraft in any given calendar year, such un-exercised purchase right aircraft will be cancelled and not be available for later exercise. 3. Purchase Right Aircraft Exercise and Business Terms. Customer may exercise a purchase right aircraft by providing Boeing with written notice not later than the first business day of the exercise month above described, which will be not less than fifteen (15) months prior to the requested aircraft delivery position, with not more than two (2) requested aircraft to be delivered in any one month. Boeing will, within thirty (30) days of Customer's notice to exercise a purchase right aircraft, notify Customer of the availability of such requested delivery position as well as alternative delivery positions, and within such thirty (30) day period the Purchase Agreement will be amended to incorporate the agreed upon additional firm purchased aircraft. The same base price and business terms as those described in the reference Purchase Agreement will apply to any such model 737-8EH purchase right aircraft delivering before 31 December 2010. However, Boeing does retain the right to increase the basic aircraft price to accommodate any mandated government or other changes made necessary for reasons of improving safety-of-flight and/or retention of the aircraft certificate of airworthiness. At the time of Customer's exercise of a purchase right aircraft, such aircraft will then become a firmly contracted aircraft and will require Customer's payment within 5 business days any advance payments due at time of exercise, per the terms of the Purchase Agreement and/or Letter Agreement No, 6-1162-DME-0707 as well as any further advance payments as may be due per the terms of the advance payment schedule described therein. 4. Firm Aircraft Termination - Excusable Delay. If any firm Aircraft are terminated by Boeing from this Purchase Agreement under Article 7, Excusable Delay, the number of Purchase Right Aircraft available to Customer under this Letter Agreement shall remain unchanged. If any firm Aircraft are terminated by Customer from this Purchase Agreement under Article P.A. No. 2910 SA-1 GOT
