STOCK PURCHASE AND REORGANIZATION AGREEMENT

This Stock Purchase and Reorganization Agreement, dated as of January 22, 2007 (this “Agreement”), is between Northwest Airlines, Inc., a Minnesota corporation (“Buyer”) and Mesaba Aviation, Inc., a Minnesota corporation (the “Company”). Capitalized terms used but not defined herein have the meanings assigned to them on Exhibit A.

WHEREAS, ▇▇▇▇ Holdings, Inc., a Minnesota corporation (“Parent”) is the sole owner of the Company’s issued and outstanding shares (the “Shares”) of common stock, par value $0.01 per share (the “Common Stock”).

WHEREAS, the Company filed on October 13, 2005 (the “Company Petition Date”), a voluntary petition (the “Company Case”) for relief under chapter 11 of Title 11 of the United States Code, 11 U.S.C. Sections 101 et seq. (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Minnesota (the “Company Bankruptcy Court”);

WHEREAS, on September 14, 2005, Buyer and certain of its Affiliates filed a voluntary petition (the “Buyer Case”) for relief under chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the “Buyer Bankruptcy Court”);

WHEREAS, the Company intends to seek the entry of an order of the Company Bankruptcy Court (the “Company Confirmation Order”) to approve the restructuring of the Company pursuant to a plan of reorganization, substantially in the form attached hereto as Exhibit B (the “Plan”, and such restructured Company, “Reorganized Company”), including the approval of this Agreement and the authorization of the Company to consummate the transactions contemplated hereby and thereby, and Buyer intends to seek the entry of an order of the Buyer Bankruptcy Court to approve this Agreement, the Allowed Claim and the authorization of Buyer to consummate the transactions contemplated hereby (the “Buyer Approval Order”);

WHEREAS, the Official Committee of Unsecured Creditors of the Company (the “Company Committee”) has agreed to submit a letter of support with respect to the Plan to be mailed to all creditors of the Company along with the Disclosure Statement and ballots; and

WHEREAS, pursuant to the Plan, the Company desires to sell to Buyer new shares of common stock representing 100 percent of the ownership interests of the Reorganized Company and to cancel the Shares.

NOW, THEREFORE, in consideration of the premises and the mutual representations, warranties, covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties, intending to be legally bound, agree as follows:

ARTICLE I

CANCELLATION AND PURCHASE AND SALE OF SHARES

1.1 Cancellation and Purchase and Sale.

(a) Upon the terms and subject to the conditions set forth in this Agreement, at or prior to the Closing and pursuant to the Plan (i) all Company Equity shall, without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled and retired and shall cease to exist and (ii) Reorganized Company shall issue and sell to Buyer and Buyer shall purchase from Reorganized Company 1,000 duly and validly authorized and issued, fully paid and nonassessable shares (the “New Shares”) of common stock, par value $.01 per share (the “New Common Stock”) of Reorganized Company, free and clear of all Liens. The transactions referred to in the foregoing clause (i) are herein referred to as the “Equity Cancellation” and the transactions referred to in the foregoing clause (ii) are herein referred to as the “New Shares Issuance”. The Equity Cancellation and the New Shares Issuance are herein collectively referred to as the “Cancellation and Issuance”.

(b) As consideration for the New Shares, Buyer agrees that, upon the consummation of the Closing, the Company Bankruptcy Estate shall have a final, non-appealable order, including the waiver of Bankruptcy Code Section 502(j) reconsideration rights, granting the Company an allowed general unsecured claim in the Buyer Case in an amount equal to $145 million plus interest on such amount from and after the petition date of Buyer’s Case (the “Buyer Petition Date”) to the extent that other general unsecured creditors of Buyer receive interest from and after the Buyer Petition Date pursuant to Buyer’s plan of reorganization (the “Allowed Claim”). The parties acknowledge and agree that the Allowed Claim will not be effective unless and until the Closing has been consummated. The Allowed Claim will be classified as a general unsecured claim in the plan of reorganization submitted to the Buyer Bankruptcy Court and supported by Buyer in the Buyer Case and will receive the same treatment in such plan of reorganization as the other general unsecured claims against Buyer. Notwithstanding anything in this Agreement to the contrary, the parties understand and agree that unless and until the Plan becomes effective, the Closing is consummated and the transactions contemplated hereby have been consummated, nothing in this Agreement or any other Transaction Document shall have, or shall be deemed to have, created an allowed claim in the Buyer Case or constitute an admission by Buyer, the Company or any of their Affiliates as to the amount, if any, of the Company’s claim against the Buyer Bankruptcy Estate, nor of Buyer’s claim against the Company Bankruptcy Estate. The parties agree that from the date of this Agreement until the Closing, the Company shall have the right to enter into a forward Contract with a Third Party to sell the Allowed Claim (the “Forward Contract”, and the aggregate consideration in exchange for the Allowed Claim, valued as of the date of the Forward Contract, provided for in the Forward Contract is herein referred to as the “Forward Price”), provided that the settlement of any such Forward Contract shall be contingent on the consummation of the Closing.

(c) From the date of this Agreement until the entry of the Company Confirmation Order, Buyer and the Company agree that Buyer, in its sole discretion, shall have the right to revise Schedule A-1 and Schedule A-4 to (i) designate any Company Agreement that

is not an Assumed Contact or a Rejected Contract as either an Assumed Contract or a Rejected Contract; it being agreed that any Company Agreement that is not so designated shall be deemed to be a Rejected Contract and (ii) designate any Company Agreement that was as of the date of this Agreement set forth on Schedule A-1 or Schedule A-4, as applicable, as (A) an Assumed Contract as a Rejected Contract and (B) a Rejected Contract as an Assumed Contract, provided that if the aggregate unsecured claim amount attributable to rejection damages with respect to any additional Rejected Contracts under clause (ii)(A) minus the aggregate unsecured claim amount attributable to rejection damages with respect to any additional Assumed Contracts under clauses (i) and (ii)(B) exceeds $1 million (the “Rejection Excess”), then Buyer will pay, simultaneous with the consummation of the Closing, to the Company Bankruptcy Estate an amount in cash equal to such Rejection Excess.

(d) Solely to the extent that the Company’s aggregate Cash (without giving effect to any proceeds received in connection with a Forward Contract) were not sufficient to satisfy the post Company Petition Date amounts set forth on Schedule 1.1(d) that are due and payable at the time of the effectiveness of the Plan (any such aggregate Cash deficiency amount, the “Deficiency”), then, simultaneous with the consummation of the Closing, Buyer shall pay to the Company Bankruptcy Estate the lesser of the Deficiency or the Cap, provided that Buyer shall under no circumstance be obligated to pay an amount that is in excess of the Cap.

(e) Each of the parties understands and agrees that unless the Closing is consummated, nothing contained in this Agreement shall constitute an admission by Buyer, the Company or any of their Affiliates as to the amount, if any, of the Company’s claim against the Buyer Bankruptcy Estate on account of rejection of that certain Airline Services Agreement between Buyer and the Company (the “ASA”) or otherwise, nor of Buyer’s claim against the Company Bankruptcy Estate. In the event that this Agreement is terminated and the transactions contemplated hereby are not consummated, Buyer expressly reserves the right to assert that the rejection damages claim of the Company from rejection of the ASA or otherwise is an amount that is lower than the Allowed Claim plus the Cap, including zero, and the Company expressly reserves the right to assert that the rejection damages claim of the Company from rejection of the ASA or otherwise is an amount higher than the Allowed Claim plus the Cap. Further, in the event that the transactions contemplated hereby are not consummated, the Company expressly reserves the right to assert that the claim of Buyer is an amount lower than the Buyer Claim, including zero, and Buyer expressly reserves the right to assert that the claim of Buyer is an amount higher than the Buyer Claim. In addition, neither Buyer nor the Company makes any representation as to the value to be distributed with respect to allowed unsecured claims in the Buyer Case or the Company Case, respectively. Except with respect to the Buyer Claim and the Allowed Claim and with respect to any matter arising out of this Agreement or any Transaction Document, upon consummation of the Closing, each of Buyer, the Buyer Bankruptcy Estate and the Company Bankruptcy Estate agrees that it has no Claims arising from the beginning of the world until the Closing Date against the other Person or the other Person’s Affiliates and that such Person shall not assert any such Claim against the other Person or the other Person’s Affiliates.

1.2 Closing. Subject to Section 1.4, on the terms and subject to the conditions set forth in this Agreement, the closing of the transactions contemplated by this Agreement (the “Closing”) shall take place: (a) at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP, One Battery

The date on which the Closing is to occur is herein referred to as the “Closing Date.”

The Company shall take all reasonably necessary actions in order to obtain approval of the Disclosure Statement and confirmation of the Plan as reasonably

(a) In the event of the termination and abandonment hereof prior to the Closing pursuant to the provisions of this Article VII, this Agreement shall become void and have no effect, and, except as provided in Section 7.2(c), each party shall pay all of its own expenses incurred in connection herewith, without any liability on the part of any party or its directors, officers or shareholders; provided, however, that if this Agreement is terminated and abandoned because either party has defaulted under or breached this Agreement, other than due to a non-willful breach of any representation or warranty by the Company or Buyer, as applicable, then the party so electing to terminate this Agreement shall be entitled to pursue, exercise and enforce any and all other remedies, rights, powers and privileges available to it at law or in equity against the other party with respect to such breach or default.

Accordingly, if the Company fails to pay the amount payable under Section 7.2(b), then the Company shall pay to Buyer all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by Buyer and its Affiliates in connection with the collection of such overdue amounts and the enforcement by Buyer of its rights under Section 7.2(b), together with interest on such overdue amounts at a rate per annum equal to the “prime rate” (as announced by JPMorgan Chase & Co. or any successor thereto) in effect on the date on which such payment was required to be made.

Except as provided in Section 7.2(c), each of the parties hereto shall pay its own fees and expenses (including the fees of any attorneys, accountants, investment bankers or others engaged by such party) in connection with this Agreement and the other Transaction Documents and the transactions contemplated hereby and thereby whether or not the transactions contemplated hereby are consummated, it being understood and agreed that all such fees and expenses of the Company shall first be paid by the Company out of its Cash (without giving effect to any proceeds received in connection with a Forward Contract), then out of any amount to be paid by Buyer to the Company Bankruptcy Estate pursuant to Section 1.1(d) and finally out of the Company Bankruptcy Estate. Buyer will pay all required filing fees under the HSR Act in connection with the transactions contemplated by this Agreement.

8.2 Survival. None of the representations and warranties contained in this Agreement or in any document delivered pursuant hereto shall survive the consummation of the Closing. It is understood and agreed that the covenants and agreements of the parties shall survive the consummation of the Closing.

8.3 Certain Interpretative Matters. The captions of Articles and Sections of this Agreement are for convenience only and shall not control or affect the meaning or construction of any of the provisions of this Agreement. As used herein, (a) words in the singular shall be held to include the plural and vice versa and words of one gender shall be held to include the other gender as the context requires, (b) the terms “hereof,” “herein,” “hereby,” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including all of the Schedules and Exhibits) and not to any particular provision of this Agreement, (c) Article, Section, paragraph, Exhibit and Schedule references are to the Articles, Sections, paragraphs, Exhibits, and Schedules to this Agreement unless otherwise specified, and (d) unless the context otherwise requires, the word “or” is not exclusive.

If any party has breached any representation, warranty or covenant contained herein, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the party has not breached shall not detract from or mitigate the fact that the party is in breach of the first representation, warranty or covenant, as the case may be.

8.5 Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by any of the parties hereto without the prior written consent of the other party (except that Buyer may assign, without the consent of the Company, (a) all of its rights and obligations under this Agreement and any other Transaction Document to any Affiliate of Buyer, any of whom may enforce its rights and remedies in connection with any such assignment, including the right to acquire the New Shares, it being agreed that no such assignment shall relieve Buyer of its obligations hereunder and (b) all of its rights and obligations under Section 1.7 to Parent). Any purported assignment or delegation in violation of this Agreement shall be null and void ab initio.

8.6 Entire Agreement. This Agreement and the other Transaction Documents (including the Schedules and Exhibits hereto and thereto) embodies the entire agreement and understanding of the parties with respect to the transactions contemplated hereby and merges in, supersedes and cancels all prior written or oral commitments, arrangements or understandings with respect thereto, including the Summary of Terms, dated December 20, 2006 between the Company and Buyer.

In addition, the parties agree that any modification or amendment of any of Schedule 1.1(d), Schedule A-2, and Schedule A-3, shall require the prior written consent of legal or financial advisors of the Company Committee. Any party hereto may, only by an instrument in writing, waive compliance by any other party hereto with any term or provision hereof on the part of such other party hereto to be performed or complied with. No failure or delay of any party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor will any single or partial exercise of any right or power, or any abandonment or discontinuance of steps to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The waiver by any party hereto of a breach of any term or provision hereof shall not be construed as a waiver of any subsequent breach. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

8.8 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and each of which shall be deemed an original, and will become effective when one or more counterparts have been signed by a party and delivered to the other party.

8.9 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF MINNESOTA THAT APPLY TO CONTRACTS MADE AND PERFORMED ENTIRELY IN SUCH STATE.

8.10 Severability. To the fullest extent that they may effectively do so under applicable Law, the parties hereto hereby waive any provision of Law which renders any provision of this Agreement invalid, illegal or unenforceable in any respect. Such parties further agree that any provision of this Agreement which, notwithstanding the preceding sentence, is rendered or held invalid, illegal or unenforceable in any respect in any jurisdiction shall be ineffective, but such ineffectiveness shall be limited as follows: (a) if such provision is rendered or held invalid, illegal or unenforceable in such jurisdiction only as to a particular Person or Persons or under any particular circumstance or circumstances, such provision shall be ineffective, but only in such jurisdiction and only with respect to such particular Person or Persons or under such particular circumstance or circumstances, as the case may be; (b) without limitation of clause (a), such provision shall in any event be ineffective only as to such jurisdiction and only to the extent of such invalidity, illegality or unenforceability, and such invalidity, illegality or unenforceability in such jurisdiction shall not render invalid, illegal or unenforceable such provision in any other jurisdiction; and (c) without limitation of clause (a) or (b), such ineffectiveness shall not render invalid, illegal or unenforceable this Agreement or any of the remaining provisions hereof.

8.11 Submission to Jurisdiction; Waivers. Each party to this Agreement hereby irrevocably and unconditionally:

(a) (i) agrees that any suit, action or proceeding instituted against it by any other party with respect to this Agreement or any other Transaction Document may be instituted, and that any suit, action or proceeding by it against any other party with respect to this Agreement or any other Transaction Document shall be instituted, only in any of the following: (A) the Company Bankruptcy Court, so long as the Company Case remains open, (B) the Buyer Bankruptcy Court, so long as the Buyer Case remains open and (C) after the completion of the Company Case or the Buyer Case, the state courts of Minnesota (and appellate courts from any of the foregoing) as the party instituting such suit, action or proceeding may in its sole discretion elect, except that any matter with respect to the Plan or its implementation must be instituted in the Company Bankruptcy Court, (ii) consents and submits, for itself and its property, to the jurisdiction of such courts for the purpose of any such suit, action or proceeding instituted against it by the other and (iii) agrees that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law;

(b) agrees that service of all writs, process and summonses in any suit, action or proceeding pursuant to Section 8.11(a) may be effected by the mailing of copies thereof by registered or certified mail, postage prepaid, to the Company or Buyer, as the case may be, at the addresses for notices pursuant to Section 8.4 hereof (with copies to such other Persons as specified therein); provided, however, that nothing contained in this Section 8.11 shall affect the right of the Company or Buyer or, as the case may be, to serve process in any other manner permitted by Law;

(c) (i) waives any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Transaction Document brought in any court specified in Section 8.11(a), (ii) waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum and (iii) agrees not to plead or claim either of the foregoing;

(d) WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY OF ANY DISPUTE ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT AND AGREES THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A JURY; and

(e) to the extent it has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself, or its property, hereby irrevocably waives such immunity in respect of its obligations with respect to this Agreement and the other Transaction Documents.

8.12 Specific Performance. Each of the parties hereto acknowledges that Buyer would not have an adequate remedy at law for money damages in the event that any of the covenants or agreements of the Company set forth in this Agreement were not performed in accordance with their terms and therefore, the Company agrees that Buyer shall be entitled to specific performance, injunctive and other equitable relief in addition to any other remedy to which it may be entitled at law or in equity (without the necessity of proving the inadequacy as a remedy of money damages or the posting of a bond).

8.13 No Presumption. With regard to each and every term and condition of this Agreement and the other Transaction Documents, the parties hereto understand and agree that the same have or has been mutually negotiated, prepared and drafted, and if at any time the parties hereto desire or are required to interpret or construe any such term or condition or any agreement or instrument subject hereto, no consideration shall be given to the issue of which party hereto actually prepared, drafted or requested any term or condition of this Agreement or any agreement or instrument subject hereto.

8.14 No Third Party Beneficiary. This Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

8.15 Representations.

(a) Notwithstanding anything contained in this Agreement to the contrary, Buyer acknowledges and agrees that the Company is not making any representations or warranties whatsoever, express or implied, beyond those expressly given by the Company in this Agreement. Except as expressly set forth in this Agreement, Buyer further acknowledges and agrees that neither the Company nor any of its Representatives has made any representation or warranty, express or implied, as to the accuracy or completeness of any information regarding the Company, its business or the transactions contemplated by this Agreement provided by the Company or its Representatives to Buyer or its Representatives, and none of the Company nor any of its Representatives will have or be subject to any liability to Buyer or its Representatives resulting from the distribution to Buyer or its Representatives, or Buyer’s use, of any such information, including any confidential memoranda distributed on behalf of the Company relating to its business or other publication or information provided to Buyer or its Representatives, or any other document or information in any form provided by the Company or its Representatives to Buyer or its Representatives in connection with the sale of the New Shares and the transactions contemplated hereby.
