(d) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT TO SUE IN ANY OTHER JURISDICTION.

SECTION 17. Waiver of Jury Trial

. EACH BORROWER AND HOLDER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS NOTE OR THE SECURITY AGREEMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF IT.

SECTION 18. Joint and Several Obligations

. The obligations of the Borrowers hereunder are joint and several. Each Borrower agrees that its obligations are a primary obligation of such Borrower and not merely a contract of surety. Each Borrower waives presentation to, demand for payment from and protest to such Borrower or any other Borrower, and also waives notice of protest for nonpayment. The obligations of Borrowers hereunder shall not be affected by (i) the failure of the Holder to assert any claim or demand or to enforce any right or remedy against any Borrower under the provisions of this Note or otherwise, (ii) any extension or renewal of any provision hereof, (iii) any rescission, waiver, compromise, acceleration, amendment or modification of any of the terms or provisions of this Note, the Security Agreement or any other Note Document, (iv) the release, exchange waiver or foreclosure of any security held by the Holder, (v) the failure of the Holder to exercise any right or remedy against any Borrower, or (vi) the release or substitution of any collateral. Each Borrower further waives any right to require that any resort be had by the Holder to any security held for payment of this Note or to any balance of any deposit, account or credit on the books of the Holder in favor of any Borrower.

Each Borrower hereby waives any defense that it might have based on a failure to remain informed of the financial condition of any other Borrower and any circumstances affecting the ability of any other Borrower to perform under this Note. Each Borrower’s obligations hereunder shall not be affected by the genuineness, validity, regularity or enforceability of this Note, the Security Agreement or any other Note Document or by the existence, validity, enforceability, perfection, or extent of any

collateral therefor or by any other circumstance which might otherwise constitute a defense to such obligations.

The obligations of the Borrowers hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including, without limitation, any claim of waiver, release, surrender, alteration, or compromise, and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegally or unenforceability of such obligations. Without limiting the generality of the foregoing, the obligations of the Borrowers hereunder shall not be discharged or impaired or otherwise affected by failure of the Holder to assert any claim or demand or to enforce any remedy under this Note or any other agreement, by any waiver or modification of any provision hereof or thereof, by any default, failure or delay, willful or otherwise, in the performance of such obligations, or by any other act or thing or omission or delay or do any other act or thing which may or might in any manner or to any extent vary the risk of any Borrower or would otherwise operate as a discharge of any Borrower as a matter of law.

Each Borrower further agrees that its obligations hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any obligation hereunder is rescinded or must otherwise be restored by Holder upon the bankruptcy or reorganization of such Borrower or otherwise.

Upon payment by any Borrower of any sums to the Holder hereunder, all rights of such Borrower against any other Borrower arising as a result thereof by way of right of subrogation or otherwise, shall in all respects be subordinate and junior in right of payment to the prior payment in full of all the obligations of the Borrowers hereunder (including interest accruing on and after the filing of any petition in bankruptcy or of reorganization of a Borrower whether or not post filing interest is allowed in such proceeding). If any amount shall be paid to such Borrower for the account of any other Borrower relating to the obligations hereunder, such amount shall be held in trust for the benefit of the Holder and shall forthwith be paid to the Holder to be credited and applied to the obligations hereunder, whether matured or unmatured.

Ladies and Gentlemen:

On April 1, 2012, you and your subsidiaries each elected to file a chapter 11 proceeding (together the “Bankruptcy Cases”) in United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”). You have advised Delta Air Lines, Inc. (“Delta”, the “Commitment Party,” “we” or “us”) that, in connection with the Bankruptcy Cases, you intend to obtain debtor-in-possession financing.

Delta is pleased to advise you of its commitment, and hereby commits to provide 100% of a $74,285,000 senior secured super-priority debtor-in-possession credit facility (the “DIP Credit Facility”) to Pinnacle Airlines Corp., a Delaware corporation (“Pinnacle”), Pinnacle Airlines, Inc., a Georgia corporation (“Pinnacle Georgia”), Pinnacle East Coast Operations Inc., a New York corporation (“Pinnacle East Coast”), Mesaba Aviation, Inc., a Minnesota corporation (“Mesaba”) and Colgan Air, Inc., a Virginia corporation (“Colgan”; and together with Pinnacle, Pinnacle Georgia, Pinnacle East Coast and Mesaba, each individually a “Company” and collectively, the “Companies”) on the terms and conditions set forth herein and in the Summary of Terms and Conditions of the $74,285,000 Senior Secured Debtor-in-Possession Facility attached hereto as Annex A (the “Term Sheet”). The Term Sheet, together with this Amended and Restated Commitment Letter, hereinafter is referred to as the “Commitment Letter.”

Delta shall act as the administrative agent and the collateral agent with respect to the DIP Credit Facility. The undersigned agrees that, without the prior written consent of the Commitment Party, (i) no additional agents or co-agents shall be appointed, or other titles conferred to any person or entity, in respect of the DIP Credit Facility, and (ii) no other lender under the DIP Credit Facility shall receive any compensation of any kind for its participation in the DIP Credit Facility.

Each Company agrees to pay (a) all costs and expenses of the Commitment Party and all other agents under the DIP Credit Facility associated with (i) the preparation, negotiation, execution, delivery, administration and enforcement of this Commitment Letter (including the Term Sheet) and the definitive documents relating to the DIP Credit Facility (the “Credit Facility Documentation”) and any amendment or waiver with respect thereto and (ii) the preparation, negotiation, execution and delivery of the Delta Connection Amendments (in each case, including the fees, disbursements and other charges of counsel and financial advisors for the Commitment Party and all other agents under the DIP Credit Facility), (b) all expenses of the Commitment Party and all other agents under the DIP Credit Facility (including the fees, disbursements and other charges of counsel and financial advisors for the Lenders) in connection with the enforcement of the Credit Facility Documentation and (c) all expenses associated with collateral monitoring, collateral reviews and appraisals, diligence, environmental reviews and fees and expenses of the Commitent Party and advisors and professionals engaged by the Commitment Party and all other agents under the DIP Credit Facility.

The Companies, jointly and severally, further agree to indemnify and hold harmless the Commitment Party, all other agents under the DIP Credit Facility, their affiliates, and their officers, directors, employees, agents and advisors (each an “Indemnified Party”) against any and all losses, claims, damages, costs, expenses (including fees, and expenses of attorneys and financial advisors) or liabilities of every kind whatsoever (collectively, the “Indemnified Obligations”) to which any of the Indemnified Parties may become subject in connection with this Commitment Letter, the DIP Credit Facility, the use or the proposed use of the proceeds thereof, the Bankruptcy Cases (solely in respect of the Commitment Party’s capacity as the Commitment Party, Administrative Agent (as defined in the Term Sheet) and/or the Lender (as defined in the Term Sheet), any other financing transaction contemplated by this Commitment Letter, any other transaction related thereto and any claim, litigation, investigation or proceeding relating to any of the foregoing and to reimburse each such Indemnified Party upon demand for any legal or other expenses incurred in connection with investigating or defending any of the foregoing, except that no Company shall be liable for any Indemnified Obligations of any Indemnified Party to the extent any of the foregoing is determined by a final and non-appealable order of a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Indemnified Party. These Indemnified Obligations will continue notwithstanding any termination of this commitment or the Commitment Letter.

Each Company agrees that all information (including but not limited to projections, the “Information”) provided by or on behalf of you and your affiliates to the Commitment Party in connection with the DIP Credit Facility and the Bankruptcy Cases may be disseminated by or on behalf of the Commitment Party and made available to prospective lenders and other persons who have agreed to be bound by customary confidentiality undertakings acceptable to the Commitment Party (whether transmitted electronically by means of a website, e-mail or otherwise, or made available orally or in writing, including at prospective lender or other meetings).

You hereby represent, warrant and covenant (and it shall be a condition to the Commitment Party’s commitment hereunder and Delta’s agreement to perform the services described herein) that (a) all written Information, other than the projections, budgets, estimates or forward-looking statements, that has been or will be made available to the Commitment Party or any other Lender by or on behalf of you or any of your representatives is or will be, when furnished, complete and correct in all material respects and does not or will not, when furnished, contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein not misleading in light of the circumstances under which such statements are made, and (b) the projections, budgets, estimates and forward-looking statements that have been or will be made available to the Commitment Party by or on behalf of you or any of your representatives have been or will be prepared in good faith based upon accounting principles consistent with the historical audited financial statements of the Companies, if applicable, and upon assumptions and methods that are believed by you to be reasonable, at the time made and at the time the related projections, estimates and forward-looking statements are made available to the Commitment Party. You agree that if at any time prior to the closing of the DIP Credit Facility, any of the representations and warranties in the preceding sentence would be incorrect if the Information was being furnished, and such representations and warranties were being made, at such time, then you will promptly supplement the Information so that such representations will be correct under those circumstances. In providing the DIP Credit Facility, the Commitment Party will be entitled to use and rely primarily on the Information without responsibility for independent verification thereof.

Each Company agrees that it shall not (and shall cause its affiliates not to), without the prior written consent of the Commitment Party attempt or agree to offer, issue, place, syndicate or arrange any debt securities or debt facilities for the Companies or any other obligor with respect to the DIP Credit Facility or make or authorize any announcement of any of the foregoing.

The obligations of the Commitment Party under this Commitment Letter are subject to, in addition to the other conditions set forth herein, and in the Term Sheet and in the definitive documentation for the DIP Credit Facility, (i) the execution and delivery of an amendment to each Delta Connection Agreement (as defined in the Term Sheet) in form and substance agreed by parties thereto (the “Delta Connection Amendments”), which Delta Connection Amendments shall be attached to the DIP motion in redacted form and such Delta Connection Amendments shall be in full force and effect, (ii) the absence, during the period from the date hereof to the closing of the DIP Credit Facility, of any change, development or event that has occurred (other than the commencement of the Bankruptcy Cases, events leading up to the commencement of the Bankruptcy Cases and matters otherwise disclosed in writing to Delta on or prior to the date hereof), which the Commitment Party shall determine has had or could reasonably be expected to have a material adverse effect on the transactions (provided, that solely the filing of an objection by any party in interest to the DIP Credit Facility, this Commitment Letter or the Amendments in the Bankruptcy Cases shall not constitute such a material change, development or event), (iii) the execution and delivery of the Credit Facility Documentation, satisfactory in form and substance to the Commitment Party on terms substantially consistent with the Term Sheet, and (iv) our not having discovered or otherwise becoming aware of information not previously disclosed to us that we believe to be materially inconsistent with the information provided to us (including pursuant to public filings) prior to the date hereof, of (x) the business, assets, properties, liabilities, operations, condition (financial or otherwise), operating results, or prospects of the Companies, taken as a whole or (y) the transactions contemplated hereby.

This Commitment Letter shall not be assignable by you without the prior written consent of us (and any purported assignment without such consent shall be null and void), and is intended to be solely for the benefit of the parties hereto and is not intended to confer any benefits upon, or create any rights in favor of, any person other than the parties hereto and the Indemnified Parties. The Commitment Party may transfer and assign its commitments hereunder, in whole or in part, to any of its affiliates or (not to be unreasonably withheld, delayed or conditioned) to any prospective lender or otherwise. Upon such assignment, the applicable Commitment Party shall be released from the portion of its commitment hereunder that has been so transferred and assigned.

It is understood and agreed that this Commitment Letter shall not constitute or give rise to any obligation on the part of the Commitment Party, any other agent or lender under the DIP Credit Facility, or any of their respective affiliates to provide any financing, except as expressly provided herein.

You acknowledge and agree that (i) no fiduciary, advisory or agency relationship between you and the Commitment Party is intended to be or has been created in respect of any of the transactions contemplated by this Commitment Letter, irrespective of whether Delta has advised or is advising you on other matters, (ii) the Commitment Party, on the one hand, and you, on the other hand, have an arm’s-length business relationship that does not directly or indirectly give rise to, nor do you rely on, any fiduciary duty on the part of Delta, (iii) you are capable of evaluating and understanding, and you understand, and accept, the terms, risks and conditions of the transactions contemplated by this Commitment Letter, (iv) you have been advised that Delta is engaged in a broad range of transactions that may involve interests that differ from your

interests and that Delta has no obligation to disclose such interests and transactions to you by virtue of any fiduciary, advisory or agency relationship, and (v) you waive any claims you may have against the Commitment Party for breach of fiduciary duty or alleged breach of fiduciary duty and agree that Delta shall have no liability (whether direct or indirect) to you in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of you, including your stockholders, employees or creditors. Additionally, you acknowledge and agree that the Commitment Party is not advising you as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. You shall consult with your own advisors concerning such matters and shall be responsible for making your own independent investigation and appraisal of the transactions contemplated hereby, and the Commitment Party shall have no responsibility or liability to you with respect thereto. Any review by the Commitment Party of the Companies, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Commitment Party and shall not be on behalf of you or any of your affiliates.

Each Company agrees that in any action arising in connection with this Commitment Letter or any transaction contemplated hereby the only damages that may be sought from the Commitment Party, all other agents and lenders under the DIP Credit Facility, or any of their affiliates or any Indemnified Party are those which are reasonably foreseeable as the result of any breach hereof. The Commitment Party, all other agents and lenders under the DIP Credit Facility and their affiliates shall not be liable under this Commitment Letter or any Credit Facility Documentation (i) for any damages arising from the use by others of information or other materials obtained through electronic, telecommunications or other information transmission systems except to the extent such damages are found in a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the willful misconduct or gross negligence of the Commitment Party, or (ii) in respect of any act, omission or event relating to the transaction contemplated hereby or thereby, on any theory of liability for any special, indirect, exemplary, consequential or punitive damages.

This Commitment Letter is for Companies’ confidential use only and may not be disclosed by any Company to any person other than (i) its respective employees, directors, attorneys and financial advisors (but not commercial lenders) and then only in connection with the proposed transaction and on a confidential need-to-know basis, (ii) where in the Companies’ reasonable judgment, disclosure is required by law or compelled in a judicial or administrative proceeding. including, without limitation, the Bankruptcy Court (in which case you agree to inform the Commitment Party promptly thereof), (iii) the Company may file this Commitment Letter (including the Term Sheet) with the Bankruptcy Court pursuant to a motion, in form and substance acceptable to the Commitment Party, seeking approval of the terms of the Commitment Letter (including the Term Sheet) and the DIP Credit Facility, (iv) with the Commitment Party’s prior written consent to the proposed disclosure and (v) to any official committee appointed in the Bankruptcy Cases (and their advisors) so long as you obtain from the applicable persons or entities a confidentiality agreement with respect to such information in form and substance acceptable to the Commitment Party. The Commitment Party reserves the right to review and approve, in advance, all materials, press releases, advertisements, and disclosures that you or your affiliates prepare that contain the Commitment Party’s or any affiliate’s name or describe the Commitment Party’s financing commitment.

The Term Sheet is intended to be indicative of the principal terms of the DIP Credit Facility and does not purport to specify all of the terms, conditions, representations and warranties, covenants and other provisions that will be contained in the final Credit Facility Documentation; provided, that the terms of the final Credit Facility Documentation shall be

substantially consistent with the Term Sheet and the Companies and the Lenders agree to negotiate the final Credit Facility Documentation in good faith.

IF THIS COMMITMENT LETTER OR ANY ACT, OMISSION OR EVENT HEREUNDER OR THEREUNDER BECOMES THE SUBJECT OF A DISPUTE, EACH OF THE UNDERSIGNED HEREBY WAIVES TRIAL BY JURY (TO THE EXTENT PERMITTED BY APPLICABLE LAW). Each Company hereby consents and agrees to the exclusive jurisdiction of (i) the Bankruptcy Court upon the commencement of the Bankruptcy Cases and, (ii) if such cases are not commenced or the Bankruptcy Court declines to exercise jurisdiction, the state or federal courts located in New York County, State of New York in any action, investigation, litigation or proceeding arising out of or relating to this Commitment Letter or any transaction relating hereto, provided that the parties acknowledge that any appeals from those courts may have to be by a court located outside of such jurisdiction. Each Company hereby expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and hereby waives any objection which any of them may have based on lack of personal jurisdiction, improper venue or inconvenient forum. This Commitment Letter shall be governed by and shall be construed in accordance with the laws of the State of New York applicable to contracts made and performed in that state.

The provisions of this letter and the Term Sheet relating to “information”, “expenses”, “confidentiality”, “indemnity”, “assignments and amendments”, “counterparts and governing law”, “venue and submission to jurisdiction” and “waiver of jury trial” shall survive the termination or expiration of this Commitment Letter and shall remain in full force and effect regardless of whether the DIP Credit Facility closes; provided that this Commitment Letter and the Term Sheet shall be superseded by the definitive Credit Facility Documentation upon the closing of the DIP Facility.

This Commitment Letter supersedes all prior discussions, writings, indications of interest and proposals with respect to the DIP Credit Facility previously delivered to you or your affiliates by the Commitment Party or any of its affiliates. Please indicate your acceptance of this commitment and return a signed copy of this Commitment Letter to the Commitment Party. This commitment and the agreements of the Commitment Party herein will expire at 11:00 p.m., New York time, on April 23, 2012, unless on or prior to such time the Commitment Party shall have received a copy of this Commitment Letter executed by you. Notwithstanding acceptance of this Commitment Letter, the commitment and the agreements of the Commitment Party herein will automatically terminate unless definitive Credit Facility Documentation is executed on or before May 18, 2012. Upon expiration or termination of the commitment contained herein, the Commitment Party and its affiliates shall have no liability or obligation hereunder. Termination of this commitment shall not affect your obligations hereunder, including your obligations to pay any costs or expenses provided for herein or in any other agreements entered into between you and the Commitment Party.

We hereby notify you that pursuant to the requirements of the USA PATRIOT Act, Title III of Pub. L. 107-56 (signed into law October 26, 2001) (the “PATRIOT Act”), each lender may be required to obtain, verify and record information that identifies each Company, which information includes the name, address, tax identification number and other information regarding each Company that will allow such lender to identify each Company in accordance with the PATRIOT Act. This notice is given in accordance with the requirements of the PATRIOT Act and is effective as to each lender.

This Amended and Restated Commitment Letter supersedes in its entirety that certain Commitment Letter, dated as of April 1, 2012, by and among the Companies and Delta.
