(d) Vendor Performance. In the event for any ***, the Delta-selected vendor of Ground Handling Functions at DTW, MSP, LGA or JFK does not meet station D0 performance goals as established by Delta or a Delta-designated entity for such period, then the ground service equipment delays coded 04A and 04B and airport ground services delays coded 11A-Z (the “Station Coded Delays”) at the applicable airport will be removed from Pinnacle’s D0 performance for the applicable Performance Period for purposes of calculating Pinnacle’s on-time departure performance pursuant to Section 2.11(b) or Section 5.14 hereof. If there are no station D0 performance goals established for the ground handler at DTW, MSP, LGA or JFK for any portion of a Performance Period, then the Station Coded Delays at such airport during such portion of a Performance Period will be removed from Pinnacle’s D0 performance for purposes of calculating Pinnacle’s on-time departure performance pursuant to Section 2.11(b) or Section 5.14 hereof. If Pinnacle or Mesaba is the ground handler in DTW, MSP, LGA or JFK, the Station Coded Delays will not be removed for purposes of this Agreement.

(e) Adjustments to Performance Standards. The Parties recognize and agree that the performance standards set forth on Schedule 2.11 may be modified or adjusted by mutual agreement of the Parties hereto from time to time during the Term of this Agreement.

Section 2.12 Service Recovery.

(a) Passenger Amenities. Pinnacle agrees to provide passenger amenities, including, without limitation, denied boarding compensation, which Delta provides under Rule 245 of the Domestic General Rules No. 1 issued by Airline Tariff Publishing Co. and ATA Resolution No. 120.20 or pursuant to any similar contractual arrangement now existing or hereafter in effect or applicable to Delta. In any Pinnacle Service City, Contracted Service City where Pinnacle or Mesaba directly contracts with a ground handler to provide Ground Handling Functions or Hub City, Pinnacle agrees (i) to handle oversold Scheduled Flights and the payment of denied boarding compensation in accordance with Delta’s standard policies and procedures, and (ii) to pay the full cost of providing passenger amenities (either directly to the affected passengers or to Delta as reimbursement for the amounts paid by Delta to such passengers) with the exception of denied boarding compensation resulting from inventory oversales or other actions of Delta.. In any Pinnacle Service City, Contracted Service City or Hub City, for denied boarding compensation resulting from inventory oversales or the actions of Delta, Pinnacle will pay the appropriate amount of denied boarding compensation to the affected passengers and will invoice Delta for such amount pursuant to Section 5.07 below. Any such invoice will include sufficient detail and supporting documentation to allow Delta to verify the invoiced amount. In Delta Service Cities or Contracted Service Cities where Delta has directly contracted with the ground handler to provide Ground Handling Functions, Delta will provide all passenger amenities, including but not limited to baggage delivery, at its sole cost.

(b) Destination by other Means. If Pinnacle or Mesaba transports a revenue passenger to his or her destination by another means (bus, train, taxi, etc.) due to a flight cancellation, Delta shall reimburse Pinnacle for the actual transportation costs incurred to transport the passenger by such other means; provided, however, that if the flight cancellation is necessitated by acts of Pinnacle or Mesaba (e.g., crew curfews, maintenance-related delays, etc.), Pinnacle will pay the costs incurred to transport the passenger by such other means. Each of Pinnacle and Mesaba shall use its best efforts to minimize the transportation of passengers by other means and the costs associated therewith.

Section 2.13 Annual Operating Plan. At least ninety (90) days prior to January 1 of each year during the Term, Pinnacle and Delta shall confer and prepare an operating plan for the succeeding calendar year, which plan shall include (i) Delta’s forecast with respect to the schedule and routing for all Scheduled Flights for such year, (ii) Delta’s forecast of the Service Cities to which Pinnacle and/or Mesaba shall operate Regional Airline Services, (iii) Delta’s forecast of specific dates for the commencement of service to new Service Cities, if any, (iv) Delta’s forecast of the number of Aircraft to be added to or removed from Pinnacle’s and Mesaba’s fleet (subject to Section 3.02), and (v) such other matters as Delta and Pinnacle shall determine (as amended in accordance with this Section 2.12, the “Annual Operating Plan”). Delta and Pinnacle shall meet and confer on a quarterly basis (or more frequently if requested by either Delta or Pinnacle) to review the implementation of the Annual Operating Plan and to discuss any changes to the Annual Operating Plan. In the event Delta elects to alter the Annual Operating Plan during the course of a year, Delta shall use its reasonable best efforts to provide at least sixty (60) days prior notice to Pinnacle. Notwithstanding the foregoing provisions of Section 2.12, Delta shall promptly notify Pinnacle of any determination by Delta to increase or decrease Pinnacle’s fleet size, and, except as provided in Section 3.02(a)(ii) and Section 3.02(a)(iii) below, Delta shall give Pinnacle no less than ninety (90) days prior notice. Delta agrees that any substantial increases in Pinnacle’s fleet size pursuant to the preceding sentence are subject to Pinnacle’s reasonable operating constraints.

(i) Equipment Additions. The Parties agree that Delta may, at its option and sole discretion, place up to an additional one hundred sixty-three (163) CRJ-200 Canadair Regional Jet Aircraft and twenty-four (24) Spare Engines in Pinnacle’s fleet. On or before April 1, 2011, Delta shall provide Pinnacle and Mesaba with the use of two (2) additional QECs (one left side with neutral and one right side with neutral), and in the event Delta fails to provide Pinnacle and Mesaba with the use of such QECs on or before such date, Delta shall reimburse Pinnacle for the actual costs Pinnacle or Mesaba incurs to procure such QECs utilizable by Pinnacle and Mesaba on such date, in an amount not to exceed Bombardier’s catalog price (at the time of each such procurement) for QECs of the same configuration, and Delta shall not hold Pinnacle or Mesaba responsible for any flight delays or cancellations associated with Pinnacle’s or Mesaba’s inability to perform due to the unavailability of the aforementioned QECs at the April 1, 2011 date, it being specifically agreed that any such delays or cancellations will be excluded from all calculations under Section 2.11 and Section 5.14.

(ii) Equipment Removal Rights. Delta and Pinnacle agree that Delta shall have the following equipment removal rights:

(A) if Delta places CRJ-200 Aircraft in Pinnacle’s fleet pursuant to the first sentence of Section 3.02(a)(i), Delta shall have the right upon at least ninety (90) days prior written notice to remove one or more such CRJ-200 Aircraft (and related Spare Engines) selected by Delta from Pinnacle’s fleet up to the number of Aircraft added by Delta pursuant to Section 3.02(a)(i).

(B) from and after the date on which Pinnacle has entered into an agreement with one or more air carriers other than Delta with respect to the operation of at least twenty (20) additional regional jet aircraft in Pinnacle’s fleet, Delta may, at its option, elect to remove one (1) CRJ-200 Aircraft and related Spare Engines selected by Delta from Pinnacle’s base fleet of one hundred twenty-four (124) CRJ-200 Aircraft (and related Spare Engines) for every two (2) regional jet aircraft operated for such other air carrier(s) which are added to Pinnacle’s fleet above the twenty (20) additional regional jet aircraft operated for such other air carrier(s); provided, however, that (1) Delta shall provide Pinnacle with at least six (6) months prior written notice of exercise of Delta’s option to remove Equipment from Pinnacle’s fleet pursuant to this provision, (2) Delta shall not remove more than twenty (20) CRJ-200 Aircraft and related Spare Engines from Pinnacle’s fleet pursuant to this provision, and in any twelve month period Delta shall not remove more than five (5) CRJ-200 Aircraft and related Spare Engines from Pinnacle’s fleet pursuant to this provision, (3) the CRJ-200 Aircraft and related Spare Engines removed from Pinnacle’s fleet pursuant to this provision shall not be operated with the Designator and shall not be operated by a third party under any type of operating, codeshare or other arrangement with Delta, and (4) Delta shall receive the CRJ-200 Aircraft and related Spare Engines removed from Pinnacle’s fleet pursuant to this provision in “as is” condition, and, notwithstanding the terms of any of the applicable Leases to the contrary, Pinnacle shall not be required to meet the return conditions contained in the applicable Leases;

(C) from and after the date on which additional aircraft are added to Pinnacle’s fleet pursuant to this Agreement or any other agreement between Pinnacle and Delta (other than pursuant to Section 2.01(b)) for a term extending at least until the Termination Date, which carry the Designator and are configured with seventy (70) or more seats (the “Replacement Aircraft”), Delta may, at its option, remove one CRJ-200 Aircraft and related Spare Engines from Pinnacle’s base fleet of one hundred twenty-four (124) CRJ-200 Aircraft (and related Spare Engines) for each Replacement Aircraft added to Pinnacle’s fleet; provided, however, that (1) Delta shall provide Pinnacle with at least six (6) months prior written notice of exercise of Delta’s option to remove Equipment from Pinnacle’s fleet pursuant to this provision, and (2) Delta shall receive the CRJ-200 Aircraft and related Spare Engines removed from Pinnacle’s fleet pursuant to this provision in “as is” condition, and, notwithstanding the terms of any of the applicable Leases to the contrary, Pinnacle shall not be required to meet the return conditions contained in the applicable Leases;

(D) in the event of a Pinnacle Change of Control, Delta may, at its option, remove CRJ-200 Aircraft and related Spare Engines from Pinnacle’s fleet pursuant to Section 5.15(b) below;

(E) from and after December 31, 2017, Delta may, at its option, remove CRJ-200 Aircraft and related Spare Engines from Pinnacle’s fleet upon the expiration of the applicable head leases;

(F) Delta shall have the right, from time to time, to remove one (1) Spare Engine selected by Delta from Pinnacle, in accordance with the terms and conditions of this sub-section; provided, however, that if the removal of any such Spare Engine from Pinnacle would adversely affect Pinnacle’s ability to satisfy maintenance and operational requirements for its fleet, taking into account Pinnacle's fleet size at the time such request is made, Pinnacle may deny such request to remove the Spare Engine. After the removal of such Spare Engine from Pinnacle pursuant to the preceding sentence, if Pinnacle, due to its operational or maintenance requirements, reasonably determines that it requires the use of such Spare Engine that has been removed at Delta’s request, Pinnacle shall notify Delta of its determination and provide reasonable justification for such determination. Upon receipt of such request, Delta shall either return the requested Spare Engine to Pinnacle within thirty (30) calendar days, or provide a matching Spare Engine to Pinnacle in like configuration to the Spare Engine previously removed from Pinnacle’s fleet within thirty (30) calendar days. In the event Delta desires to exercise its rights hereunder, Delta will provide Pinnacle at least thirty (30) days notice, designating therein the Spare Engine to be removed. Delta may designate the same or a different Spare Engine in the event it shall exercise its rights hereunder on more than one occasion. Pinnacle shall re-deliver such Spare Engine to Delta in compliance with the applicable Return Conditions (as defined in the Lease for such Spare Engine (the “Spare Engine Lease”)), provided that such Spare Engine shall have a minimum of 1,000 cycles remaining until the next scheduled maintenance visit with Standard Aero and shall have all line replaceable units installed and in serviceable condition, as when the Spare Engine was originally delivered to Pinnacle. The Spare Engine Lease will be terminated at the date of re-delivery hereunder. As consideration for the foregoing, Delta shall pay to Pinnacle *** per month (prorated for any partial month) for the period from and including the termination date of the Spare Engine Lease and continuing until the earlier of (x) the Termination Date and (y) the date on which Delta returns such Spare Engine to Pinnacle and a new Spare Engine Lease is executed. Subject to the preceding sentence, should Delta determine to return such Spare Engine to Pinnacle, Delta (i) shall give Pinnacle thirty (30) days’ advance notice of each such return of a Spare Engine and (ii) shall return such Spare Engine to Pinnacle in compliance with the Return Conditions (as defined in the Spare Engine Lease), provided that such Spare Engine shall have a minimum of 1,000 cycles remaining until the next scheduled maintenance visit with Standard Aero and shall have all line replaceable units installed and be in serviceable condition, as when the Spare Engine was originally removed from Pinnacle’s fleet. At the time of return of each Spare Engine in accordance with the terms hereof, the Parties shall enter into a new Spare Engine Lease with respect to such Spare Engine, identical as to terms with the original Spare Engine Lease, excepting only the effective date of such new Spare Engine Lease; and

(G) With respect to the additional QECs, the use of which Delta will provide to Pinnacle pursuant to the last sentence of Section 3.02(a)(i), Delta may request the removal of up to two (2) such QECs (left side plus neutral/right side plus neutral) from Pinnacle upon 30 days written notice to support other CRJ-200 fleet requirements, and Pinnacle shall not unreasonably delay its response or deny such request; provided, however, that if the removal of any such QECs from Pinnacle would adversely affect Pinnacle’s ability to satisfy maintenance and operational requirements for its fleet, taking into account Pinnacle's fleet size at the time such request is made, Pinnacle may deny such request to remove and re-position the QECs. After the removal of one or more QECs from Pinnacle pursuant to the preceding sentence, if Pinnacle, due to its operational or maintenance requirements, reasonably determines that it requires the use of any QECs that have been removed and re-positioned at Delta’s request, Pinnacle shall notify Delta of its determination and provide reasonable justification for such determination. Upon receipt of such request, Delta shall either return the requested quantity of QECs to Pinnacle within thirty (30) calendar days, or provide a matching quantity of QECs to Pinnacle in like configuration to those previously removed from Pinnacle’s fleet within thirty (30) calendar days. Delta agrees that the QECs it provides to Pinnacle to use shall be in serviceable condition at the time of such provision, and Pinnacle agrees that any QECs removed from its fleet by Delta shall be in serviceable condition at the time of such removal. Delta agrees to pay for all costs associated with the transportation of QECs to and from Pinnacle.

In the event any Equipment is removed from Pinnacle’s fleet, Pinnacle shall cooperate with Delta in good faith with respect to transition services, transfer of aircraft records and related ancillary arrangements. For the avoidance of doubt, each of Delta’s Equipment removal rights pursuant to this Section 3.02(a)(ii) is independent of each other removal right, and the exercise of removal rights under one provision shall not reduce Delta’s removal rights under any other provision, except as it may effect Pinnacle’s determinations regarding the removal or need for replacement of QECs as set forth above.

(iii) Additional Equipment Removal Rights. Notwithstanding Section 3.02(a)(ii), in the event of (A) a labor action or other event giving rise to Delta’s right to terminate this Agreement pursuant to Section 10.03(e) and (B) Delta has not yet exercised its termination rights, (1) Delta shall have the right to terminate Leases for, and take immediate possession of, up to seventy-four (74) CRJ 200 Aircraft and related Spare Engines selected by Delta, and (2) if the labor action or other event continues beyond 45 days Delta shall have the right to select and terminate Leases for, and take immediate possession of, up to that number of CRJ 200 Aircraft in excess of fifty (50) and the related Spare Engines.

(iv) Unscheduled Aircraft. Subject to Pinnacle’s approval, which shall not be unreasonably withheld, Delta shall determine the appropriate level of unscheduled Aircraft to be included in Pinnacle’s fleet from time to time.

(v) Spare Engine Requirements. With respect to the appropriate quantity of Spare Engines to be included in Pinnacle’s fleet in the event of Aircraft removal or placement of additional Aircraft with Pinnacle, Delta and Pinnacle shall mutually determine the appropriate quantity of Spare Engines to be included in Pinnacle’s fleet from time to time.

Section 3.03 Lease of the Equipment. As of the Effective Date, Pinnacle and Delta (and/or an Affiliate of Delta) are parties to Leases with respect to the one hundred twenty-four (124) CRJ-200 Aircraft, nine (9) Spare Engines and two (2) QECs in Pinnacle’s fleet and Mesaba and Delta (and/or an Affiliate of Delta) are parties to Leases with respect to seventeen (17) CRJ-200 Aircraft, one (1) Spare Engine and two (2) QECs in Mesaba’s fleet. In the event Delta adds any additional Aircraft in Pinnacle’s fleet pursuant to Section 3.02(a)(i), such additional Aircraft will be leased by Delta to Pinnacle pursuant to a lease that will be in substantially the same form as the Leases with respect to the CRJ-200 Aircraft in Pinnacle’s fleet as of the Effective Date. Pinnacle and Delta agree to enter into leases with respect to the QECs Delta will provide to Pinnacle pursuant to Section 3.02(a)(i) on substantially the same terms as the Leases with respect to the QECs in Pinnacle’s fleet as of the Effective Date, and such leases shall remain in effect for the Term, subject to the termination rights and other terms and conditions consistent with Section 3.02(a)(ii)(G) above.

Section 3.04 Terms of the Leases. Each Lease for the CRJ-200 Aircraft and the Spare Engines shall include the following terms:

(a) the term of each Lease shall be for a period ending on the Termination Date; provided, however, no Lease shall be for a term longer than the term of the related head lease, if any;

(d) the Leases shall include such terms as are necessary to conform provisions of the Leases to the head lease and to any ancillary documents actually entered into by Delta or its affiliate in connection with such Equipment (to the extent Delta requests conformation).

Notwithstanding the foregoing provisions of this Section 3.04 or the provisions of any Lease, the Parties agree that the security deposit for the one hundred twenty-four (124) CRJ-200 Aircraft in Pinnacle’s fleet as of the date hereof shall equal the *** currently deposited with Delta and no additional security deposit shall be required for the placement of up to nineteen (19) additional CRJ-200 Aircraft with Pinnacle. The security deposit for CRJ-200 Aircraft placed at Pinnacle in excess of such nineteen (19) Aircraft shall be equal to one month’s rent per each additional Aircraft. The security deposit required for the placement of other aircraft at Pinnacle with fifty-one (51) or more seats shall be equal to one month’s rent per each additional aircraft. Notwithstanding the foregoing, this provision shall not apply to the Extra Aircraft.

Delta represents and warrants to Pinnacle that the obligations of Lessee with regard to return conditions under each of the Leases under which Mesaba is Sublessee are not, in the aggregate, more onerous than those contained in that certain Sublease Agreement [NW 2002 HHH], dated as of January 14, 2003, between Delta (as successor to Northwest Airlines, Inc.), as sublessor, and Pinnacle, as sublessee.

Section 3.05 Manufacturer Benefits Agreement. Delta (as successor by merger to Northwest) and Pinnacle are parties to a Manufacturer Benefits Agreement dated as of January 14, 2003.

Section 3.06 Equipment Maintenance, Servicing and Cleaning. Subject to Section 3.11 with respect to the Extra Aircraft, each of Pinnacle and Mesaba shall be responsible for all aspects of the maintenance in accordance with the Maintenance Program (including any maintenance or modifications required by FAA airworthiness directives and all routine and non-routine maintenance), servicing and cleaning (including painting of aircraft exteriors and replacement of worn interior items) of the Equipment (except for ground handling as specified in Section 4.02); provided, however, that with respect to the Canadair Regional Jet Aircraft and Spare Engines, Pinnacle shall utilize Standard Aero for all major shop-level engine maintenance and shall utilize Bombardier for heavy airframe maintenance in accordance with the Standard Aero Agreement and the Bombardier Agreement, respectively. In the event Pinnacle is or becomes a party to such Agreements, Pinnacle shall not execute any amendment or side letter to any of those Agreements without Delta’s prior written consent. In the event spare engine and/or spare parts pooling agreements are established for Delta Connection Carriers, each of Pinnacle and Mesaba will participate in such agreements so long as such agreements reasonably address Pinnacle’s inventory needs, logistics requirements and configuration concerns. In the event Delta enters into agreements for auxiliary power unit (APU) maintenance, avionics maintenance and/or landing gear overhauls with respect to the Aircraft, Pinnacle and Mesaba shall utilize the vendors in such agreements for such services; provided, however, Pinnacle’s and Mesaba’s utilization of such vendors shall be subject to (i) termination of Pinnacle’s or Mesaba’s (as applicable) existing vendor contracts, if any, and Delta’s payment of any early termination penalties imposed pursuant to Pinnacle’s and Mesaba’s contracts and (ii) reasonably satisfactory arrangements in respect of Pinnacle’s and Mesaba’s operational requirements.

Section 3.07 Third Party Guarantees and Warranties. Pinnacle shall administer, track and pursue warranty and guaranty claims under the purchase, support and service agreements for the Equipment, so as to minimize operating costs for the Equipment. Such efforts shall include establishment of all systems and procedures necessary to track and submit warranty and guaranty claims, including providing reports and information required to be provided under the purchase, support or services agreement. Pinnacle shall not operate or maintain the Equipment in a manner that could result in any warranty or guaranty being terminated or voided, without the prior written consent of Delta.

Section 3.08 Related Transfer Arrangements. All leases and subleases of ground support equipment, simulators, tooling and spare parts inventory agreements and vendor and/or maintenance agreements relating to items used primarily for or services provided primarily to the Equipment (collectively “Support Agreements”) entered into by Pinnacle after the Initial Effective Date and by Mesaba after the Effective Date shall be assignable to Delta without the consent of the other party to such Support Agreement on termination of this Agreement. Each of Pinnacle and Mesaba shall, at Delta’s option, assign to Delta such Support Agreements as Delta shall designate on termination of this Agreement.

TERM AND TERMINATION

Section 10.01 Term. The 2003 ASA was made effective as of January 1, 2003 (the “Initial Effective Date”), and the 2007 Restatement made effective as of January 1, 2007. This Agreement shall become effective on the Effective Date and, unless earlier terminated as provided herein, shall continue in effect until December 31, 2017 and shall thereafter automatically be extended for successive five (5) year renewal periods (each a “Renewal Term”) unless Delta gives not less than two years’ advance notice of non-renewal prior to December 31, 2017 or the commencement of any Renewal Term, in which case the Agreement will terminate on December 31, 2017 or the last day of the then applicable Renewal Term, as the case may be, such period in which this Agreement remains in effect, including any Renewal Terms, is hereinafter referred to as the “Term”.

Section 10.02 Termination by Either Party.

(a) In the event that Pinnacle Corp., Pinnacle or Delta (i) makes a general assignment for the benefit of creditors or becomes insolvent, (ii) files a voluntary petition in bankruptcy, (iii) petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its business or any substantial part of its assets, (iv) commences under the laws of any competent jurisdiction any proceeding involving its insolvency, bankruptcy, reorganization, readjustment of debt, dissolution, liquidation or any other similar proceeding for the relief of financially distressed debtors, (v) becomes the object of any proceeding or action of the type described in (iii) or (iv) above and such proceeding or action remains undismissed or unstayed for a period of at least thirty (30) days, or (vi) is divested of a substantial part of its assets for a period of at least thirty (30) days, then Pinnacle Corp. or Pinnacle (in the event the foregoing occurs with respect to Delta) or Delta (in the event the foregoing occurs with respect to Pinnacle Corp. or Pinnacle) may by written notice terminate this Agreement immediately.

(b) Except as otherwise provided in Section 10.03, in the event of a breach of a nonmonetary provision of this Agreement by any Party remaining uncured for more than thirty (30) days after receipt of written notification of such default by the nondefaulting Party, or in the case of a breach requiring more than thirty (30) days notice to cure, the defaulting Party does not begin and pursue with due diligence a method of cure within thirty (30) days after receipt of written notification specifying in reasonable detail the nature of such default from the nondefaulting Party, then the nondefaulting Party may terminate this Agreement at its sole option; provided, however, in the case of a breach by Pinnacle of Section 2.11(c), Delta shall not be permitted to terminate this Agreement unless a breach by Pinnacle of such section shall remain uncured for a period of ninety (90) days or more.

(c) In the event of a breach of a monetary provision of this Agreement by either Party and such default remaining uncured for more than thirty (30) days after receipt of written notification specifying in reasonable detail the nature of such default from the nondefaulting Party, then the nondefaulting Party may terminate this Agreement at its sole option. Notwithstanding the foregoing or any other provision of this Agreement, if between the Effective Date and March 31, 2011 Delta notifies Pinnacle of Delta’s intent to terminate this Agreement pursuant to this Section 10.02(c), and the default by Pinnacle or Mesaba giving rise to such notice of termination is due to an act or omission of Mesaba occurring prior to the Effective Date, then Pinnacle and Mesaba shall have ninety (90) days after receipt of such notice to cure such default and if such default is not cured within such 90-day period, Delta shall have the right to terminate this Agreement immediately and at its sole option.

Section 10.03 Termination by Delta. Notwithstanding the provisions of Section 10.02(b), Delta shall have the right to terminate this Agreement immediately and at its sole option if:

(a) Pinnacle or Mesaba shall default in the payment of any amount due under any Lease and such default shall continue for more than the period of grace, if any, specified therein and shall not have been waived.

(b) Pinnacle or Mesaba shall default with respect to any other terms of any Lease, such default shall continue for more than the period of grace, if any, specified therein and shall not have been waived.

(c) Pinnacle shall fail to comply with the provisions of Section 9.03 and, as a result thereof, the insurance required thereunder is not in effect.

(d) Pinnacle’s failure to pass, in Delta’s reasonable discretion, a safety and codeshare audit to be conducted by Delta, at its sole discretion, at any time during the Term of this Agreement.

(e) More than fifty percent (50%) of the Aircraft do not operate any Scheduled Flights for more than seven (7) consecutive days or twenty-five percent (25%) of the Aircraft do not operate any Scheduled Flights for more than twenty-one (21) consecutive days, other than as a result of (i) an FAA order which grounds all commercial flights of all air carriers or grounds a specific Aircraft type of all air carriers, (ii) a scheduling action by Delta, or (iii) Delta’s inability to perform its obligations under this Agreement as a result of a strike by Delta employees.

(f) Pinnacle’s or Mesaba’s FAA or DOT Certification is for any reason revoked or otherwise not in full force and effect so as to permit Pinnacle or Mesaba to perform the Regional Airline Services required under this Agreement.

(g) Pinnacle, Mesaba or a Pinnacle Affected Company shall commence operating an aircraft type that causes Delta to be in violation of its collective bargaining agreement with its pilots as in effect on the Effective Date.

(h) Pinnacle or Mesaba shall default with respect to the material terms of any other agreement between Pinnacle or Mesaba and Delta (any such agreement, a “Related Party Agreement”), and such default shall continue for more than the period of grace, if any, specified therein and shall not have been waived; provided, however, that each of (i) the 2007 CRJ-900 Delta Connection Agreement; (ii) the SAAB Agreement and (iii) the ▇▇▇▇ ▇▇▇-▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ Agreement shall not be a Related Party Agreement hereunder until July 1, 2011.

Notwithstanding the foregoing or any other provision of this Agreement, if between the Effective Date and March 31, 2011 Delta notifies Pinnacle of Delta’s intent to terminate this Agreement pursuant to Section 10.03(b)(but only with respect to Leases relating to Aircraft operated by Mesaba), 10.03(d) or 10.03(f) above, and the default by Pinnacle or Mesaba giving rise to such notice of termination is due to an act or omission of Mesaba occurring prior to the Effective Date, then Pinnacle and Mesaba shall have ninety (90) days after receipt of such notice to cure such default and if such default is not cured within such 90-day period, Delta shall have the right to terminate this Agreement immediately and at its sole option.

Section 10.4 Effect of Termination. Termination of this Agreement for any reason shall not relieve any Party of rights and obligations incurred prior to the effective date of termination. A Party’s right to terminate this Agreement shall be in addition to any other rights or remedies, in law or equity, available to such party.

Section 11.10 Severability. If any term of this Agreement shall be judicially determined to be illegal, invalid or unenforceable at law or in equity, it shall be deemed to be void and of no force and effect to the extent necessary to bring such term within the provisions of any such applicable law or laws, and such terms as so modified and the balance of the terms of this Agreement shall remain enforceable.

Section 11.12 Availability of Equitable Remedies; Procedures.

(a) In the event of a breach by either Party of any provision of this Agreement, the nonbreaching Party may give notice thereof to the breaching Party, which notice shall specify in reasonable detail the nature of the breach and shall demand that the breaching Party either cure the breach or refrain from conduct constituting the breach (herein the “conduct”), as may be applicable. If (i) the breaching Party has not cured the breach or refrained from the conduct, as may be applicable, within ten (10) days following receipt of the notice from the nonbreaching Party, or (ii) the breaching Party does not begin within ten (10) days following receipt of the notice to pursue with reasonable diligence a method of cure or begin to take steps toward ceasing the conduct where the breach or conduct is such that it requires more than ten (10) days to cure or to cease, as may be applicable, then the nonbreaching Party may seek to compel performance by the breaching Party in accordance with the provisions of paragraph (b) below. If, upon receiving a notice contemplated by this paragraph (a), a breaching Party believes that a breach has not occurred or that the conduct specified in the notice does not constitute a breach of the provisions of this Agreement, but the breaching Party nonetheless cures the alleged breach or refrains from the conduct within ten (10) days following receipt of such notice, such Party may thereafter proceed in accordance with the provisions of paragraph (b) below to seek a determination of whether a breach occurred or whether the specified conduct constituted a breach of the provisions of this Agreement.

(b) Because a breach of the provisions of this Agreement could not adequately be compensated by money damages, any Party shall be entitled, following notification in accordance with the provisions of paragraph (a) above, to an injunction restraining such breach or threatened breach and to specific performance of any provision of this Agreement and, in either case, no bond or other security shall be required in connection therewith, and the Parties hereby consent to the issuance of such injunction and to the ordering of specific performance. Further, in the event any Party refrains from the conduct of any activity alleged in a notice received pursuant to paragraph (a) above to constitute a breach of the provisions of this Agreement, such Party may thereafter proceed promptly to bring an action in the District Court, County of Hennepin, State of Minnesota, for an expedited judicial determination as to whether the conduct specified constitutes a breach of the provisions of this Agreement and, upon a determination that the conduct does not constitute a breach, such Party may promptly thereafter recommence such conduct.

Section 11.13 Exhibits. The Exhibits attached hereto are intended to be an integral part of this Agreement and are incorporated into the Agreement by reference for all purposes.

Section 11.14 Integration and Entire Agreement. This Agreement (including the Exhibits) and the ancillary documents entered into in connection therewith are intended by the Parties as a complete statement of the entire agreement and understanding of the Parties with respect to the subject matter hereof and all matters between the Parties related to the subject matter herein and therein set forth. This Agreement may only be amended or modified by a written agreement between Pinnacle, on the one hand, and Delta, on the other, which specifically references this Agreement and expressly provides for such amendment.

Section 11.15 Relationship of Parties. Nothing in this Agreement shall be interpreted or construed as establishing between the Parties a partnership, joint venture or other similar arrangement.

Section 11.16 2007 Restatement. The Parties agree that the 2007 Restatement is hereby amended and restated effective as of the Effective Date. It is the intent of the Parties hereto that all rights, privileges, obligations and duties of the Parties arising prior to the Effective Date, including the calculation of any amounts due to any Party in respect of such period, shall be governed by the provisions of the 2007 Restatement; and all rights, privileges, obligations and duties of the Parties arising from and after the Effective Date, including the calculation of any amounts due to any Party in respect of such period, shall be governed by the provisions of this Agreement.

Section 11.17 Parent Guarantee.

(a) Pinnacle Corp. hereby unconditionally and irrevocably guarantees to Delta the due and punctual performance by Pinnacle and Mesaba of each of such Party’s respective obligations, agreements and covenants arising under this Agreement and under each term and condition hereof (collectively, the “Obligations”). If Pinnacle or Mesaba shall fail or be unable to perform any such Obligation as and when the same shall be required to be performed, then Pinnacle Corp., at its sole cost and expense, shall be obligated to promptly perform or cause to be promptly performed each such Obligation in accordance with the terms hereof and thereof. This guaranty is a guaranty of payment, performance and compliance and not of collectibility and is in no way conditioned or contingent upon any attempt to collect from or enforce performance or compliance by Pinnacle or Mesaba or upon any other event or condition whatsoever. If for any reason any payment Obligation amount shall not be paid by Pinnacle or Mesaba when due, Pinnacle Corp. shall immediately pay such amount to the person entitled thereto pursuant to this Agreement, as if such amount constituted the direct and primary obligation of Pinnacle Corp. and regardless of whether any person has taken any steps to enforce any rights against such Party to collect such amount.

(b) Pinnacle hereby unconditionally and irrevocably guarantees to Delta the due and punctual performance by Mesaba of each of Mesaba’s Obligations. If Mesaba shall fail or be unable to perform any such Obligation as and when the same shall be required to be performed, then Mesaba, at its sole cost and expense, shall be obligated to promptly perform or cause to be promptly performed each such Obligation in accordance with the terms hereof and thereof. This guaranty is a guaranty of payment, performance and compliance and not of collectibility and is in no way conditioned or contingent upon any attempt to collect from or enforce performance or compliance by Mesaba or upon any other event or condition whatsoever. If for any reason any payment Obligation amount shall not be paid by Mesaba when due, Pinnacle shall immediately pay such amount to the person entitled thereto pursuant to this Agreement, as if such amount constituted the direct and primary obligation of Pinnacle and regardless of whether any person has taken any steps to enforce any rights against Mesaba or Pinnacle Corp. to collect such amount.

(c) To the fullest extent permitted under applicable law, the obligations of Pinnacle Corp. and Pinnacle hereunder shall be absolute and unconditional, shall be continuing and remain in full force and effect until final and irrevocable payment or performance, and shall not be released, discharged, affected or impaired in any respect by: (a) any amendment, modification, or cancellation of, or addition or supplement to this Agreement; (b) any exercise, acceleration, extension, compromise, settlement, non-exercise, waiver, release, or cancellation by Delta of any right, remedy, power or privilege under or related to this Agreement or any other guaranty of any obligations of either Pinnacle or Mesaba; (c) the invalidity or unenforceability, in whole or in part, of this Agreement; (d) any change in the corporate existence, structure or ownership of either Pinnacle Corp., Pinnacle or Mesaba or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of them or their assets; or (e) any other occurrence, circumstance, happening or event whatsoever, whether similar or dissimilar to the foregoing, whether foreseen or unforeseen, and any other circumstance which might otherwise constitute a legal or equitable defense, release or discharge of the liabilities of a guarantor or surety, or which might otherwise limit recourse against Pinnacle Corp. or Pinnacle. If acceleration of the time for the performance or payment of any Obligation is stayed upon the insolvency, bankruptcy or reorganization of Pinnacle or Mesaba, all Obligations that are subject to acceleration under the terms of this Agreement shall nonetheless be performed or payable hereunder by Pinnacle Corp. or Pinnacle, as applicable.

(d) Each of Pinnacle Corp. and Pinnacle hereby specifically agrees that it shall not be necessary or required as a condition to enforcement of the obligations hereunder against it, that there be (and each of Pinnacle Corp. and Pinnacle, to the fullest extent permitted by applicable law, specifically waives) diligence, presentment, or protest of any kind whatsoever with respect to the respective guaranty by Pinnacle Corp. and Pinnacle or the Obligations; such waiver includes, without limitation: (i) presentment for payment upon Pinnacle Corp., Pinnacle or Mesaba or the making of any protest; (ii) any requirement to exhaust any remedies exercisable upon a default under this Agreement or to give any notice of non-performance or non-payment; (iii) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety; or (iv) so long as any Obligation remains outstanding, any right of subrogation by virtue of any performance or payment made hereunder. Each of Pinnacle Corp. and Pinnacle agrees that any payment or performance of the Obligations guaranteed by it hereunder or other act that tolls any statute of limitations applicable to enforcement of the Obligations shall similarly operate to toll any statute of limitations applicable to any liability of Pinnacle Corp. or Pinnacle pursuant to this Section 11.17. In addition, to the fullest extent permitted by applicable law, each of Pinnacle Corp. and Pinnacle waives the benefit and advantage of any and all valuation, stay, appraisement, extension or redemption laws which, but for this provision, agreement and waiver, might be applicable to any sale made under any judgment, order or decree of any court or otherwise based on the respective guaranty of Pinnacle Corp. and Pinnacle pursuant to this Section 11.17. All waivers made by Pinnacle Corp. or Pinnacle in this Section 11.17 are intentional and made by Pinnacle Corp. or Pinnacle, as applicable, after due consideration of all the consequences thereof.

(e) All of the terms and conditions of this Section 11.17 shall be binding upon and shall inure to the benefit of the respective successors and assigns of the Parties; provided that neither Pinnacle Corp. nor Pinnacle may assign, delegate or otherwise transfer any of its rights or obligations hereunder without the prior consent of Delta.

Attached as Exhibit F-1 is the Parties’ agreement with respect to pass travel benefits made available to Pinnacle upon the effective date of the 2003 ASA.

Without expanding or limiting (or modifying in any way) any of the Parties’ rights and obligations with respect to pass travel benefits as set forth in the 2003 ASA, the Parties acknowledge and agree that the space available leisure pass travel benefits under Delta’s Pass Travel Policies applicable to employees of Pinnacle and Mesaba as of the Effective Date (other than with respect to paragraph III.10 in Exhibit F-1) are set forth in Exhibit F-2 attached hereto.

F-1

Exhibit F-1

PASS TRAVEL PRIVILEGES

Overview

It is understood and agreed that Northwest has purchased and therefore controls all seat inventory on Northwest coded flights operated by Pinnacle Airlines subject to the Airline Services Agreement entered into by Northwest and Pinnacle Airlines. Northwest, in its sole discretion, shall set all prices and control all seat inventory on Pinnacle flights operated under the Northwest code.

Seats on Northwest coded flights operated by Pinnacle have an intrinsic value to Northwest and by definition persons occupying perishable seats, either on a positive space or space available basis, have revenue opportunity costs (displacement, dilution, etc.) to Northwest. Northwest will therefore establish the policies for utilizing its valuable and perishable product inventory. Northwest shall have the right, in its sole discretion, to establish pass travel policies for all persons on all Northwest Flights, including those operated by Pinnacle Airlines.

II.	Definitions

“Northwest Flights” shall mean all flights operated by Northwest or Pinnacle Airlines under the Northwest designator code. If and to the extent Northwest enters into an agreement with any regional carrier other than Pinnacle Airlines that provides for pass travel on the terms set forth herein, the term “Northwest Flights” shall include the flights operated by such carrier under the Northwest designator code.

“Pinnacle Business Travel” shall mean employee travel that is required to run Pinnacle Airlines’ operations, perform employee job functions, meet with Pinnacle Airlines vendors, attend company/industry meetings/training, or conduct company business.

By definition, business travel to conduct company business would require a meeting with another person (internal or external) and the vast majority of the trip’s duration should be related to the business objective. If a pleasure trip is taken in conjunction with a business trip, the pleasure portion must be flown space available. Examples:

1. Extend business trip for personal reasons before/after.

Example: Business trip from city A to city B. After meeting is complete, employee extends trip by 2 days in city B for personal reasons. Return flight from city B is leisure space available at the employee’s normal boarding priority.

2. Round ▇▇▇▇▇. Business trip from city A to B. After business is complete, employee travels from city B to city C for personal reasons, then returns to city A.

- Flights from B to C and C to A are leisure space available.

Things that would not quality as “Business” would be

- Emergency travel, funeral travel, etc.

- Familarization trips to visit cities where no business is conducted

- Employee recognition/rewards

- Any travel related to personal reasons

-	Any travel by any person who is not an employee, such as a spouse or family member

In enforcing Northwest’s business travel policies, Pinnacle Airlines must exercise good faith in determining what is valid company business and in doing so must comply with Northwest’s business travel definition and policies, as such definitions and policies may be changed from time to time by Northwest in its sole discretion.

“Leisure Travel” shall mean any travel that does not qualify as Pinnacle business travel.

III.	Travel Privileges of Pinnacle Airlines Employees on Northwest Flights

1.	Travel Authority Cards.

Northwest shall have the sole authority to issue travel authority cards for travel on Northwest Flights (which by definition includes Northwest coded flights operated by Pinnacle Airlines). Pinnacle Airlines will not be entitled to issue travel authority cards on Northwest Flights; however, it may submit a request for the issuance of travel authority cards for travel on Northwest to the Northwest Pass Bureau and Northwest, in its sole discretion, shall determine whether or not to grant any such request.

2.	Requests for Travel Passes on Behalf of Any Person Other Than Employees/retirees/family members of employees of Pinnacle Airlines.

Any request for pass travel on Northwest Flights for any person other than employees, retirees or family members of employees of Pinnacle Airlines (for example, employees of airlines other than Pinnacle Airlines) may be submitted to the Northwest Pass Bureau for approval and Northwest, in its sole discretion, shall determine whether or not to grant any such request.

3.	Ticket Donations.

Northwest agrees to provide Pinnacle Airlines with 20 positive space (inventory controlled) tickets per year for charitable donations to be made at Pinnacle Airline’s discretion.

4.	Collateral (i.e., free tickets, upgrades, Worldclub passes, elite memberships, etc.).

Northwest agrees to provide Pinnacle Airlines with $100,000 per year of collateral to be used for Pinnacle Airline’s business purposes (i.e., for sales, marketing, service recovery, etc.). Northwest shall determine from time to time the types of collateral to be made available to Pinnacle Airlines and the unit cost for each type of collateral product. The list of collateral products and the unit costs thereof as of the date hereof are set forth on Attachment A attached hereto. Ordering will be handled via Northwest’s GMS process.

5.	Business Travel by Pinnacle Employees on Northwest Flights.

A.	Officers and Board of Directors of Pinnacle Airlines:

Northwest agrees to issue to the President and CEO of Pinnacle Airlines an F1 positive space travel card that is valid for travel on Northwest Flights by the President and CEO and his or her spouse and eligible dependent children so long as such officer is employed by Pinnacle Airlines. This card will be valid for business or leisure travel.

Pursuant to his prior employment agreement, Northwest will issue to ▇▇▇▇ ▇▇▇▇▇▇, Vice President & Chief Financial Officer of Pinnacle Airlines a Y1 positive space travel card that is valid for travel on Northwest Flights by ▇▇. ▇▇▇▇▇▇ and his spouse and eligible dependent children so long as ▇▇. ▇▇▇▇▇▇ is employed by Pinnacle Airlines. This card will be valid for business or leisure travel.

Northwest will issue to other officers of Pinnacle Airlines (up to a maximum of 8 individuals) travel privileges on Northwest Flights consistent with the travel privileges to which managing directors of Northwest are entitled from time to time. Currently such privileges are as follows:

Business Travel: B1/F2 travel card.

Leisure Travel:

8 B1 trip events per year.

Members of the Board of Directors of Pinnacle Airlines who are not employees will be entitled to receive a Y1 positive space travel card that is valid for travel by such Board member and his or her spouse and eligible dependent children on Northwest Flights operated by Pinnacle. The card will be valid for Pinnacle business purposes and for leisure travel only. The card will not be valid for business travel on behalf of any person, company or entity other than Pinnacle Airlines.

B.	Other Management (Exempt) Employees of Pinnacle Airlines.

Pinnacle Airlines may designate up to 150 management (exempt) employees who will be eligible for B1 (coach positive space, capacity controlled) business travel on Northwest Flights. Pinnacle Airlines shall submit the list of such employees to Northwest annually and Northwest may, in its sole discretion, approve or disapprove any employee whose name appears on such list for such travel privileges.

All other management (exempt) employees of Pinnacle Airlines who are not entitled to the travel privileges described in B.1) above may travel on Northwest Flights with boarding priority 2W, and, to the extent Pinnacle Airlines desires that any such employee travel on a Northwest Flight for Pinnacle business purposes with higher priority, Pinnacle Airlines may submit its request for positive space travel to the Northwest Pass Bureau for approval. Northwest, in its sole discretion, shall determine whether or not to grant any such request.

C.	Non-Management (Non-Exempt) and Contract Employees of Pinnacle Airlines.

Non-management (non-exempt) and contract employees of Pinnacle Airlines must request approval from the Northwest Pass Bureau for any travel on Northwest Flights for Pinnacle Airlines business purposes. Northwest, in its sole discretion, shall determine whether or not to grant any such request. Any such approved travel for Pinnacle Airlines business purposes by such employees shall be on a space available basis.

D.	Pinnacle Airlines Operational Travel Requirements.

Deadhead travel and travel for pilot or flight attendant FAA-mandated training. Pinnacle Airlines may book travel on Northwest Flights with boarding priority of B1 for pilot and flight attendant deadhead and FAA-mandated travel. The purpose of such travel must be supported by crew scheduling, crew bid reports, training schedules or other records of Pinnacle Airlines’ operations. Such records must be maintained for not less than one (1) year and made available for audit by Northwest upon request.

-	Any deadhead booking must contain the following restriction:

CRJ FUEL BURN (PENALTY) FORMULAS

Note: The formulas below are to be used for the calculation of fuel burn penalty as it pertains to each performance measure and the All-in Rate. The penalty, while settled on an annual basis, is based on a monthly calculation. The result of the calculation for each performance measure shall be netted together to produce a net penalty, if one should exist. To the extent that formulas do not yet exist (i.e., Cruise Speed and Altitude), the Parties mutually agree to document those formulas when those performance measures are implemented. Per Section 5.05(d), the All-in Rate is first adjusted for the variances that exist with respect to each performance measure, and then to the extent an unfavorable variance to budget exists, the penalty formula below for the All-in Rate is applied. A penalty is assessed if the cause of variance is deemed within the control of Pinnacle. An example for a month is illustrated in Attachment 1 hereto.

1. Excess Planned Fuel on Arrival (FOA)

Monthly Penalty:

(Average Actual FOA in lbs-Target) x CTC / ***/ Block Hours per Cycle x Total Block Hours x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

·	Block Hours based on scheduled and unscheduled operations/cycles that returned legitimate FOA values (on the flight history database)

·	Cost to Carry (CTC) varies with average enroute time; CTC = (*x Avg ETE) *

·	Fuel cost per gallon = actual price per gallon incurred by Delta per Section 5.05(a)(ii) including into-plane fees and taxes.

2. Excess Planned Zero Fuel Weight (ZFW)

Monthly penalty:

(Average Planned ZFW - Average Actual ZFW-target tolerance in lbs) x CTC x CTC / ***/ Block Hours per Cycle x Total Block Hours x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

·	Block Hours based on scheduled and unscheduled operations

·	Cost to Carry (CTC) varies with average enroute time; CTC = (*x Avg ETE) *

·	Fuel cost per gallon = actual price per gallon incurred by Delta per Section 5.05(a)(ii) including into-plane fees and taxes.

H-1

3. Excess Auxiliary Power Unit (APU) Burn

Monthly Penalty:

(Average Actual APU hrs per flight hour-Target) x Flt to Blk Hour Ratio x Total Block Hours x *** x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

·	APU burn rate = *** per Bombardier (w/Air and electric load)

·	APU runs almost exclusively w/air load but not necessarily electric. Reduction in rate w/electric removed insignificant per 9E

·	Flight hours and Block hours based on all 9E operations (scheduled and unscheduled)

·	Fuel cost per gallon = actual price per gallon incurred by Delta per Section 5.05(a)(ii) including into-plane fees and taxes.

4. Cruise Speed

To be determined.

5. Cruise Altitude

To be determined.

6. All-in Rate

(To be applied after adjusting for known variances to performance measures above as shown in the sample calculation set forth in Attachment 1 hereto)

Monthly Penalty:

(Actual All-in Gallons per block hour-Target) x Total Block Hours x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

·	Fuel cost per gallon = actual price per gallon incurred by Delta per Section 5.05(a)(ii) including into-plane fees and taxes.

B. Definitions

“Pay” is the sum of all customer service/reservation, agent, ramp service and mechanic employees pay, including any bonus payments, within a classification (i.e. customer service agents) and shall exclude Premiums and any overtime premium.

“Parity Pay” shall be the sum of all customer service/reservation, agent, ramp service and mechanic employees Pay re-calculated using the Parity Pay Scale in place of actual Pay rates.
