(2) GUARANTEE TERM The term of the Guarantee is [Confidential Portion Deleted] commencing on the first day of the month next succeeding the month in which Buyer's first Aircraft enters into revenue service (hereinafter referred to as "Guarantee Term"). Unless earlier terminated or suspended as provided herein, all provisions of this Guarantee and BRAD's obligation hereunder, shall terminate on the last day of the Guarantee Term. (B) DEFINITIONS (1) "Aircraft Schedule Reliability Target" shall mean the target for the Covered Aircraft set forth in attachment A hereto. (2) Each "Reporting Period" during the Guarantee Term shall be the longer of (a) six (6) consecutive months or (b) the number of full months required for all Covered Aircraft to accumulate a minimum of 1,500 scheduled revenue departures. The initial Reporting Period shall commence on the first day of the Guarantee Term. (3) A "Chargeable Aircraft Schedule Interruption" shall be defined as an interruption, that results directly from Verified Malfunction(s) of any Aircraft components, equipment or parts, excluding Engines and Engine related components specified by the Engine manufacturer, installed on the Covered Aircraft upon its delivery to Buyer, which results in a cancellation, turn back, diverted landing or departure delayed longer than fifteen (15) minutes. (4) "Verified Malfunction(s)" shall mean failures, or malfunctions of any component mentioned above during a Reporting Period and where such failures or malfunctions are the primary cause of an interruption and are subsequently confirmed by inspection or shop test, if applicable, in accordance with Buyer's FAA approved maintenance programs. [CONFIDENTIAL PORTION DELETED] -2- 94 (5) "Scheduled Revenue Departure" with respect to a Covered Aircraft, shall be any scheduled departure of such Covered Aircraft for a scheduled revenue flight segment, and any one-segment canceled revenue flights. (6) The "Achieved Aircraft Schedule Reliability" for a Covered Aircraft shall be calculated and expressed as a percentage by use of the following formula: Any rounding, as required under this Guarantee, in order to compare the Achieved Aircraft Schedule Reliability with the Aircraft Schedule Reliability Targets, shall be accomplished as follows: if the first digit of the portion to be dropped from the number to be rounded is five or greater, the preceding digit shall be raised to the next higher number. (7) A "Deficiency" occurs when the Achieved Schedule Reliability during any Reporting Period is less than the Aircraft Scheduled Reliability Target for such Reporting Period, all as may be adjusted pursuant to the terms of this Guarantee. (C) REMEDIAL ACTION (1) If, for any Reporting Period during the Guarantee Term, Buyer notifies BRAD that the Achieved Aircraft Schedule Reliability is below the applicable Aircraft Schedule Reliability Target and the contents of the applicable reports mentioned in Section (D)(1) confirm the contents of Buyer's notification, then BRAD shall: (i) investigate circumstances and the possible causes for excessive interruptions, and (ii) [CONFIDENTIAL PORTION DELETED]. (2) If, at the end of the next Reporting Period after which the foregoing recommended remedial actions have been accomplished it is Buyer's and BRAD's opinion based on Buyer's notification that the Achieved Aircraft Schedule Reliability is [CONFIDENTIAL PORTION DELETED], then BRAD shall: [CONFIDENTIAL PORTION DELETED]. (D) ADMINISTRATIVE REQUIREMENTS (1) Buyer shall submit to BRAD within thirty (30) days after the Reporting Period, the total number of Chargeable Aircraft Schedule Interruptions and the total number of Scheduled Revenue Departures during the preceding six (6) months. Notwithstanding what is stipulated above, during any Reporting Period when any Guarantee remedies are being provided by BRAD to Buyer, Buyer shall submit to BRAD monthly reports of Chargeable Aircraft Schedule Interruptions. -3- 95 Each report shall also include the average Achieved Aircraft Schedule Reliability for all of the previous Reporting Period for the relevant year of the Guarantee Term, if any. (2) Upon request, Buyer shall submit to BRAD reasonable proof that any interruption claimed by Buyer to constitute a Chargeable Aircraft Schedule Interruption does in fact constitute a Chargeable Aircraft Schedule Interruption. Buyer shall maintain and submit to BRAD such records, data and reports as may reasonable be required to (i) determine Achieved Aircraft Schedule Reliability, (ii) analyze the problems encountered and the causes thereof, and (iii) when required, develop appropriate remedial action. (3) BRAD may require Buyer to furnish, from time to time, such additional information as is reasonably necessary to monitor Chargeable Aircraft Schedule Interruptions or investigate any related schedule reliability problem. (4) Buyer shall maintain complete records referred to above in support of all reports required from Buyer under this Guarantee and such records shall be retained by Buyer for a minimum of one year after submittal of the report to which they pertain. All such records and any other data in Buyer's possession reasonably required for the proper administration of this Guarantee shall, upon request, be made available at Buyer's facilities for examination by BRAD.

(6) All reports under this Guarantee shall be submitted by Buyer to the attention of: (E) COMPLIANCE AND VALIDITY If at any time Buyer is deficient in forwarding the Achieved Aircraft Schedule Reliability as defined in Section (D) in this Guarantee on the due dated during or after [CONFIDENTIAL PORTION DELETED]. (F) GENERAL CONDITIONS AND LIMITATIONS (1) The Aircraft Schedule Reliability Targets defined in Section (B)(1) herein and set forth in Attachment A hereto are based on certain factors controlled by Buyer revenue service operations such as annual utilization, average stage length, average turnaround time, average thru-stop time and certain other maintenance and operational factors under Buyer's control. These factors are identified in Attachment A hereto. If, for any Reporting Period, the Covered Aircraft experience changes in any such factors, the Aircraft Schedule Reliability Target for such Reporting Period shall be adjusted: -4- 96 (i) to reflect changes in the schedule reliability parameters set forth in Attachments A, if any such parameter increases or decreases by more than [CONFIDENTIAL PORTION DELETED]. Then the Aircraft Schedule Reliability Target will be reviewed by both parties. The intent of such review shall be for the parties to agree upon a reasonable adjustment to the targets to compensate for the change in operations; (ii) to reflect changes that cause "Other Flight Profile Factors" to exceed the limits set forth in Attachment A, by mutual agreement between BRAD and Buyer. (2) If BRAD or any Vendor issue no-charge service bulletins or service bulletins with no-charge retrofit kits which, when incorporated, will improve Aircraft Schedule Reliability, Buyer shall implement such at the earliest reasonable time, but in no event later than [CONFIDENTIAL PORTION DELETED] by mutual agreement between BRAD and Buyer to be consistent with Buyer's FAA approved maintenance program, such period commencing with the date of Buyer's receipt of such service bulletins or sufficient retrofit kits to support Buyer's reasonable installation schedule for such kits. [CONFIDENTIAL PORTION DELETED]. (3) BRAD shall have the right (after consultation with Buyer) to inspect and review Buyer's maintenance facilities, programs and procedures as they relate to this Guarantee. If BRAD recommends in writing reasonable changes in Buyer's maintenance programs and procedures which are economically feasible and would, based on data submitted by BRAD to Buyer, improve the Achieved Aircraft Schedule Reliability, and Buyer does not effect such changes or delays effecting such changes beyond the period specified in Section (F)(2) above for effecting service bulletins, BRAD and Buyer shall negotiate an equitable adjustment to the occurrences which will thereafter constitute a Chargeable Aircraft Schedule Interruption.
