OMNIBUS AGREEMENT

This OMNIBUS AGREEMENT is dated January 15, 2003, and is between Pinnacle Airlines Corp., a Delaware corporation (“Pinnacle Corp.”), Northwest Airlines, Inc., a Minnesota corporation (“Northwest”), Northwest Airlines Corporation, a Delaware corporation (“NWA Corp.”), and Aon Fiduciary Counselors, Inc., a Delaware corporation, solely in its capacity as independent fiduciary for the Plans referred to below in connection with the transactions contemplated by this Agreement (in such capacity, “Fiduciary Counselors”).

Preamble

1.             NWA Inc. (“NWA”), an indirect wholly owned Subsidiary of NWA Corp. and the wholly owning parent of Northwest, owns 86,842 shares (the “Pinnacle Airlines Shares”) of common stock, par value $0.01 per share, of Pinnacle Airlines, Inc., a Georgia corporation (“Pinnacle Airlines”), such Pinnacle Airlines Shares being all of the issued and outstanding capital stock of Pinnacle Airlines.  When this Agreement becomes effective, Pinnacle Airlines will declare and pay to NWA a dividend consisting of a promissory note payable to the order of NWA in the principal amount of $200,000,000 (the “Note”).  NWA will then transfer the Pinnacle Airlines Shares to Pinnacle Corp. (which previously will have had no assets or operations) in exchange for the issuance by Pinnacle Corp. to NWA of (i) 15,000,000 shares (the “Pinnacle Corp. Shares”) of its common stock, par value $0.01 per share (the “Pinnacle Corp. Stock”), (ii) one share (the “Series A Preferred Share”) of Series A Preferred Stock, par value $0.01 per share, of Pinnacle Corp. which, upon issuance and together with the Pinnacle Corp. Shares, will constitute all of the issued and outstanding capital stock of Pinnacle Corp., (iii) a guaranty of the Note, (iv) guaranties of certain aircraft lease obligations of Pinnacle Airlines to Northwest, and (v) guaranties of certain aircraft sublease obligations of Pinnacle Airlines to Northwest.  NWA will then Transfer the Pinnacle Corp. Shares and the Series A Preferred Share to Northwest as a contribution to the capital of Northwest.

2.             Northwest has minimum funding requirements pursuant to ERISA Section 302 and Code Section 412 for Plan Years 2002, 2003 and 2004 that are due in calendar years 2003 and 2004 for each of the Northwest Airlines Pension Plan for Contract Employees, Northwest Airlines Pension Plan for Pilot Employees and Northwest Airlines Pension Plan for Salaried Employees (each, a “Plan” and, collectively, the “Plans”).

3.             Northwest seeks to have the ability to contribute some or all of the Pinnacle Corp. Shares to the Plans in lieu of cash to satisfy Northwest’s minimum funding requirements that are due in calendar years 2003 and 2004.  Northwest may also contribute Pinnacle Corp. Shares during calendar years 2003 and 2004 with respect to a Plan for which there is no minimum funding requirement, creating a credit balance for such Plan.

4.             Since the contribution of the Pinnacle Corp. Shares to the Plans would otherwise be prohibited under Sections 406 and 407 of ERISA and Section 4975 of the Code, Northwest has applied to the Department of Labor for exemptive relief under Section 408(a) of ERISA and Section 4975(c)(2) of the Code, and, in connection therewith, Northwest has engaged Fiduciary Counselors as an independent fiduciary for the Plans to negotiate and approve the terms upon which the Plans would accept the Pinnacle Corp Shares contributed to the Plans by Northwest

and the other terms that would apply to such Pinnacle Corp. Shares once such shares are contributed to the Plans.  Northwest and Fiduciary Counselors entered into a letter agreement dated as of November 5, 2002 (the “Plan Fiduciary Agreement”), whereby Northwest engaged Fiduciary Counselors as independent fiduciary for the Plans in connection with the contemplated contributions.

5.             This Agreement reflects, among other things, the terms upon which Northwest and Fiduciary Counselors have agreed that the Pinnacle Corp. Shares may be contributed to and held by the Plans.

each conduct an appraisal of such non-cash consideration.  The Principals’ Experts will then submit their respective appraisals to a third nationally-recognized independent valuation expert chosen by the Principals’ Experts who will choose one of such submissions as the value of such non-cash consideration (the “Final Determination”).  The reasonable fees and expenses of the nationally-recognized independent valuation expert reasonably acceptable to Fiduciary Counselors and Northwest, the Principals’ Experts and any other nationally-recognized independent valuation expert chosen by the Principals’ Experts to make the Final Determination will be paid by Northwest.  Northwest will have 21 days from the later of (i) the receipt of the Offer Notice or (ii) receipt of the Final Determination to agree or decline to purchase all of such Plan Shares at the offered price and on the other economic terms stated in the Offer Notice.  If, at the end of such 21-day period (or such longer period as necessary to make the Final Determination), Northwest declines to purchase such Plan Shares, the Plans have 90 days to sell such Plan Shares to the Initial Offeror pursuant to the terms and conditions of the bona fide written offer and at a price not less than the offered price.

Section 6.3. Limitation on Series A Preferred Stock Blocking Rights.  In the event any of the Plans seek to Transfer Plan Shares following the occurrence of an Early Termination Event with respect to which transaction Northwest would otherwise have blocking rights by virtue of its ownership of the Series A Preferred Share, and subject to Section 6.4, Northwest will not exercise the rights provided by the Series A Preferred Share to block such transaction.

Section 6.4. Scope Clause Limitation.  Subject to the ability of the Plan Shares to be Transferred in accordance with clauses (i), (ii) and (iii) of Section 6.1, Plan Shares may not be Transferred directly or indirectly in any manner (whether after the right of first refusal provided for in Section 6.2, a Business Combination otherwise permitted by Section 6.3 or in a Transfer following the occurrence of an Early Termination Event) that would result in Northwest being in violation of Section 1 C (or a successor provision) of the Northwest Pilots Agreement (the “Scope Clause”).

Section 6.5. Commercially Reasonable Efforts; Expenses of Financial Advisor.  In the event of a proposed Transfer of Plan Shares other than pursuant to Article VIII, the Plans will (a) exercise commercially reasonable efforts to maximize the amount realized for such Plan Shares and (b) follow customary procedures, including but not limited to the retention of a nationally-recognized investment banking firm as financial advisor to assist in such sale process, that would be applicable to a transaction of similar magnitude and character.  Northwest will pay the reasonable expenses of such financial advisor in connection with the services provided to the Plans by such financial advisor.

Section 6.6. Prohibited Transfers.  Any attempted Transfer in violation of the terms of this Agreement will be ineffective to vest in the purported transferee any right, title or interest in or to the Pinnacle Corp. Shares purported to be Transferred and such Transfer will be void ab initio.  Neither Pinnacle Corp. nor Northwest will recognize the holder of such Pinnacle Corp. Shares for any purpose, including without limitation for purposes of the IPO, for purposes of recognizing voting rights, or the right to receive dividends or other distributions with respect to such Plan Shares.

Shares will be stamped or otherwise imprinted with a legend in substantially the following form (with the second paragraph being applicable to Plan Shares only):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR AN EXEMPTION FROM REGISTRATION, UNDER SAID ACT.

Section 7.2. Certain Approval Rights.  (a)  Beginning when the Plans hold more than 50% of the issued and outstanding Pinnacle Corp.

Stock, and if in accordance with Section 7.3(b) Fiduciary Counselors is required to vote Plan Shares on such matter as recommended by the board of directors of Pinnacle Corp., then the separate requirement under this Section 7.2(a)(D) that the Plan Director must have voted to approve such matter will not apply).

(b)           with respect to any contemplated Business Combination or other matter requiring approval of the holders of the Pinnacle Corp. Stock, as recommended by the board of directors of Pinnacle Corp., provided that, the terms of such Business Combination or other transaction do not treat the Plan Shares differently than any other Pinnacle Corp.

ARTICLE VIII

PUT OPTION

Section 8.1. Exercise of the Put Option.  (a)  On the terms and subject to the conditions described in this Agreement, Northwest hereby grants to the Plans an irrevocable option (the “Put Option”) to require Northwest to purchase at any time and from time to time any or all of the Plan Shares.  In order to exercise the Put Option, the Plans must deliver to Northwest written notice specifying the particular Plan Shares as to which the Put Option is being exercised, specifying the date on which such shares were contributed to the Plans, the Floor Price of such shares and the Market Value of such shares.  The date on which Fiduciary Counselors provides Northwest with notice of its election to exercise the Put Option is the “Put Exercise Date.”  Any exercise of the Put Option will be deemed to be a contemporaneous exchange for equivalent new value.  The Put Option is personal to the Plans and may not be assigned to any other Person.

(b)           Subject to Section 8.3, no later than the applicable Put Closing Date, Northwest will, against delivery to Northwest of the certificates for the Plan Shares as to which the Put Option is being duly exercised accompanied by duly executed stock powers, pay to the Plans in immediately available funds the applicable Put Price for each such share.  The “Put Price” is the greater of the Floor Price applicable to such share and the Market Value of Pinnacle Corp. Stock with respect to which the Put Option has been exercised.

Section 8.2. Put Closing Date.  (a)  Subject to Section 8.7, the closing date of the purchase and sale of Plan Shares with respect to which the Put Option has been exercised by Fiduciary Counselors (the “Put Closing Date”) will be the 30^th calendar day after such notice is delivered to Northwest (or, if such date is not a Business Day, the next succeeding Business Day), or such other date as Northwest and Fiduciary Counselors may agree.  However, Northwest will have the right at any time, subject to clause (f) of this Section 8.2, but no later than five Business Days prior to such 30^th calendar day, to defer such Put Closing Date beyond such 30^th calendar day (such fifth Business Day preceding such 30^th calendar day being referred to as the “Deferral Election Deadline”) for the applicable additional period described below in this Section 8.2 in order to enable Northwest to arrange for the Plan Shares as to which the Put

-24-

Option has been exercised (together with other Pinnacle Corp. Shares, if Northwest so elects) to be sold in an IPO or other registered public offering or to a third party selected by Northwest.

(b)           The maximum period by which Northwest may defer a particular Put Closing Date will be determined by the amount of Northwest Liquidity as of the date of the latest internal financial reports that are available when the deferral election is made by Northwest:

(i)            If Pinnacle Corp. has not yet consummated an IPO by the Put Exercise Date and the aggregate value of all Pinnacle Corp. Shares theretofore contributed to the Plans is equal to or less than $225,000,000 (as measured at the time of each respective Contribution):

(A)          If Northwest Liquidity is equal to or greater than $1,750,000,000, Northwest may defer the Put Closing Date for up to an additional 150 days;

(B)           If Northwest Liquidity is equal to or greater than $1,500,000,000 and less than $1,750,000,000, Northwest may defer the Put Closing Date for up to an additional 90 days;

(C)           If Northwest Liquidity is equal to or greater than $1,250,000,000 and less than $1,500,000,000, Northwest may defer the Put Closing Date for up to an additional 60 days.

(ii)           If Pinnacle Corp. has not yet consummated an IPO by the Put Exercise Date and the aggregate value of all Pinnacle Corp. Shares theretofore contributed to the Plans is greater than $225,000,000 (as measured at the time of each respective Contribution) and equal to or less than $325,000,000:

(A)          If Northwest Liquidity is equal to or greater than $1,750,000,000, Northwest may defer the Put Closing Date for up to an additional 150 days;

(B)           If Northwest Liquidity is equal to or greater than $1,600,000,000 and less than $1,750,000,000, Northwest may defer the Put Closing Date for up to an additional 90 days;

(C)           If Northwest Liquidity is equal to or greater than $1,500,000,000 and less than $1,600,000,000, Northwest may defer the Put Closing Date for up to an additional 60 days.

(iii)          If Pinnacle Corp. has not yet consummated an IPO by the Put Exercise Date and the aggregate value of all Pinnacle Corp. Shares theretofore contributed to the Plans is greater than $325,000,000 (as measured at the time of each respective Contribution):

(A)          If Northwest Liquidity is equal to or greater than $1,750,000,000, Northwest may defer the Put Closing Date for up to an additional 120 days;

(B)           If Northwest Liquidity is equal to or greater than $1,600,000,000 and less than $1,750,000,000, Northwest may defer the Put Closing Date for up to an additional 60 days;

-25-

(C)           If Northwest Liquidity is equal to or greater than $1,500,000,000 and less than $1,600,000,000, Northwest may defer the Put Closing Date for up to an additional 30 days.

(c)           If at the time the Put Option is exercised the Pinnacle Corp. Stock is Publicly Traded, the maximum deferral period specified in subclauses (A), (B) and (C) of clauses (i), (ii) and (iii) of paragraph (b) of this Section 8.2 will be shortened by 30 days each, provided that the period in (iii)(C) will remain at 30 days.

(d)           Notwithstanding the foregoing, if during any period during which the Put Closing Date has been deferred in accordance with this Section 8.2 Northwest Liquidity falls below the threshold amount that served as the basis for initially determining the duration of the deferral period, then the deferral period will be shortened to the lesser of (i) the number of days remaining in the original deferral period, or (ii) the number of days of deferral permitted in accordance with the foregoing provisions based on such lower level of Northwest Liquidity.  Conversely, if during the deferral period then in effect Northwest Liquidity increases to the minimum threshold applicable to the next higher maximum deferral period (as compared to the minimum threshold that was most recently applicable in determining the deferral period then in effect), then the deferral period will be lengthened to that which would have been in effect had Northwest Liquidity had originally been at such threshold level.  These adjustments to the deferral period will be made from time to time as warranted by the changing level of Northwest Liquidity.  Northwest will advise Fiduciary Counselors immediately upon any such adjustment being warranted.

(e)           Northwest and Fiduciary Counselors may agree on further extensions of the Put Closing Date subject to collateral arrangements being entered into that are satisfactory to Fiduciary Counselors.

(f)            Northwest’s right to defer a Put Closing Date pursuant to the foregoing provisions of this Section 8.2 is contingent upon its delivery to Fiduciary Counselors, on or before the Deferral Election Deadline, a detailed written calculation of Northwest Liquidity based on the latest internal financial reports then available.  Such written calculation shall be accompanied by a certificate of an officer of Northwest certifying such calculation.

(g)           In the event of (i) the non-compliance by Fiduciary Counselors and the Plans with their obligations described in Section 8.3(b) or (ii) the failure of the Plans to deliver to Northwest on the Put Closing Date a certificate of the trustee of the Plans to the effect that, as of such Put Closing Date, the Plans own beneficially and of record all of the Plan Shares as to which Fiduciary Counselors has exercised the Put Option, free and clear of all Encumbrances, then in the case of either (i) or (ii) the related exercise of the Put Option by Fiduciary Counselors will be deemed to have been withdrawn.

Section 8.3. Underwritten Public Offering or Sale to Third Party.  (a)  On or prior to the applicable Put Closing Date, in lieu of purchasing the Plan Shares as to which the Put Option has been exercised, Northwest will have the option to arrange for such shares to be sold in an underwritten public offering or to a third party selected by Northwest.  In such event, the purchase and sale of such shares shall occur no later than the applicable Put Closing Date.

-26-

(b)           Actions by the Plans.  At the request of Northwest and in contemplation of such underwritten public offering or sale to a third party, Fiduciary Counselors will, on behalf of the Plans, enter into customary transactional documents relating to such underwritten public offering or sale to a third party, provided that, in no event will the Plans be obligated to (i) provide representations and warranties in such documents beyond due authorization, good title, no conflicts and other customary representations and warranties of sellers in similar transactions or (ii) provide indemnities beyond those customary for sellers in similar transactions or (iii) pay any of the fees, costs or expenses of any such underwritten public offering or sale to a third party.  In no event will Fiduciary Counselors or the Plans be required to provide any representations or warranties or indemnities as to information relating to Northwest, Pinnacle Corp. or Pinnacle Airlines or any of their respective Affiliates.

(c)           Proceeds of Underwritten Offering or Sale.  In lieu of the Put Price, the Plans will retain all of the net proceeds from the underwritten public offering or sale to a third party, as contemplated by this Section 8.3, of the Plan Shares as to which the Put Option has been exercised.

(i)            If the net proceeds received by the Plans in such underwritten public offering, on a per share basis, are equal to or greater than the applicable Floor Price, Northwest’s obligations under the Put Option with respect to such Plan Shares will be deemed to have been fully discharged.  If the net proceeds received by the Plans in a sale to a third party of such Plan Shares, on a per share basis, are equal to or greater than the Market Value of such shares, Northwest obligations under the Put Option with respect to such Plan Shares will be deemed to have been fully discharged.

(ii)           If the net proceeds received by the Plans in such underwritten public offering of such Plan Shares, on a per share basis, are less than the applicable Floor Price, Northwest will be obligated, no later than the applicable Put Closing Date, to remit to the Plans immediately available funds in an amount equal to the number of shares of Pinnacle Corp. Stock that have been thus sold times the excess of the applicable Floor Price over the net proceeds per share received by the Plans in such underwritten public offering (subject to adjustment in accordance with Section 8.5(b)).  Upon making such payment, Northwest’s obligations under the Put Option with respect to such Plan Shares will be deemed to have been fully discharged.

(iii)          If the net proceeds received by the Plans in such sale to a third party of such Plan Shares, on a per share basis, are less than the Market Value of such shares, Northwest will be obligated, no later than the Put Closing Date applicable to the Plan Shares sold to a third party, to remit to the Plans immediately available funds in an amount equal to the number of shares of Pinnacle Corp. Stock that have been thus sold times the excess of the Market Value of such Plan Shares over the net proceeds per share received by the Plans in such sale transaction (subject to adjustment in accordance with Section 8.5(b)).  Upon making such payment, Northwest’s obligations under the Put Option with respect to such Plan Shares will be deemed to have been fully discharged.

Section 8.4. Suspension of the Put Option.  Fiduciary Counselors may not exercise the Put Option with respect to any particular Plan Shares, if on the date that would otherwise be the Put Exercise Date (i) the Pinnacle Corp. Stock is Publicly Traded and has a Market Value of

-27-

not less than 110% of the Floor Price applicable to such Plan Shares and (ii) such Plan Shares are Freely Tradable.  The provisions of this Section 8.4 will not affect the right of Fiduciary Counselors to exercise the Put Option with respect to (y) such Plan Shares on another Put Exercise Date when the Pinnacle Corp. Stock has a Market Value of less than 110% of the applicable Floor Price or such Plan Shares are not Freely Tradeable or (z) other Plan Shares.

Plan Shares are “Freely Tradable” when Pinnacle Corp. Stock is Publicly Traded and the applicable Plan Shares are either (i) eligible to be sold under Rule 144(k) to the Securities Act or (ii) able to be sold under an effective shelf registration statement on Form S-3 that is not then subject to a blackout, lockup or other restriction on or suspension of sales thereunder.

Section 8.5. Termination of the Put Option; “Cap” on Put Price.  (a)  The Put Option will terminate with respect to any particular Plan Shares on the date on which (i) such Plan Shares are Freely Tradable, (ii) more than 50% of the outstanding shares of Pinnacle Corp. Stock are held by the public and are Publicly Traded, and (iii) one of the following applies with respect to the Floor Price of each such Plan Share:

(A)          if the Plans own less than 10% of the outstanding Pinnacle Corp. Stock on such date, the weighted average daily trading price of such Pinnacle Corp. Stock is not less than 110% of the Floor Price applicable to such remaining Plan Share for any 30 trading days within the prior 60 consecutive trading day period;

(B)           if the Plans own at least 10% but less than 25% of the outstanding Pinnacle Corp. Stock on such date, the weighted average daily trading price of such Pinnacle Corp. Stock is not less than 110% of the Floor Price applicable to such remaining Plan Share for any 60 trading days within the prior 90 consecutive trading day period; or

(C)           if the Plans own at least 25% but less than 50% of the outstanding Pinnacle Corp. Stock on such date, the weighted average daily trading price of such Pinnacle Corp. Stock is not less than 110% of the Floor Price applicable to such remaining Plan Share for any 90 trading days within a 120 consecutive trading day period;

provided that such periods specified in clauses (A) through (C) above will be tolled for any applicable black-out, lock-up or other restricted trading period.

(b)           If, in an IPO that is not initiated by Northwest in response to an exercise of the Put Option by Fiduciary Counselors, Fiduciary Counselors could sell all of the Plan Shares then held by the Plans at that time, but elects to sell less than all of such Plan Shares and the net proceeds per share in such IPO are equal to or greater than the Floor Price, the Put Option will expire with respect to such voluntarily retained Plan Shares.  If in such IPO, the net proceeds per share are less than the Floor Price, with respect to such voluntarily retained Plan Shares, Northwest’s maximum payment obligation with respect to the Put Option applicable to such voluntarily retained Plan Shares will be equal to the excess of (i) the aggregate Floor Price for such Plan Shares over (ii) the net proceeds per share received in such IPO.

-28-

Section 8.6. Anti-Dilution Adjustment.  (a)  If Pinnacle Corp. (x) subdivides the outstanding Pinnacle Corp. Stock into a greater number of shares (for example, by means of a stock split) or (y) combines the outstanding Pinnacle Corp. Stock into a smaller number of shares (for example, by means of a reverse stock split), the Floor Price then in effect will be adjusted on a proportionate basis, and such adjusted Floor Price will be applicable to the Plan Shares originally held, as well as to any additional shares of Pinnacle Corp. Stock received in respect of such Plan Shares as a consequence of any such subdivision.

(b)           If Pinnacle Corp. makes or issues a dividend or other distribution payable in additional shares of Pinnacle Corp. Stock, the Floor Price then in effect will be decreased by multiplying such Floor Price by a fraction, the numerator of which is one and the denominator of which is one plus the number of such shares received in such dividend or other distribution in respect of each such Plan Share, and such adjusted Floor Price will be applicable to the Plan Shares originally held as well as to the additional shares of Pinnacle Corp. Stock received as a dividend or other distribution in respect of such originally held Plan Shares.  If Pinnacle Corp. makes or issues a dividend or other distribution consisting of cash, the Floor Price will be decreased by the amount of cash received in respect of each Plan Share in such dividend or other distribution.

(c)           If any of the following events occur, namely (x) any reclassification, reorganization or change of outstanding shares of Pinnacle Corp. Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination of the Pinnacle Corp. Stock), (y) any consolidation, merger or combination of Pinnacle Corp. with or into another corporation as a result of which holders of Pinnacle Corp. Stock are entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Pinnacle Corp. Stock, or (z) any sale or conveyance of the properties and assets of Pinnacle Corp. as, or substantially as, an entirety to any other entity as a result of which holders of Pinnacle Corp. Stock are entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Pinnacle Corp. Stock (the “Exchange Consideration”), then the Plans must either (i) exercise the Put Right in accordance with Article VIII with respect to the Plan Shares to be exchanged for the Exchange Consideration such that the Put Closing Date occurs prior to the Plans’ right to receive of the Exchange Consideration (i.e., Northwest will have the right to receive the Exchange Consideration in exchange for such Plan Shares) or (ii) accept the Exchange Consideration in lieu of exercising the Put Right, in such case the Put Right will expire with respect to the Plan Shares to be exchanged for the Exchange Consideration.

(d)           If Pinnacle Corp. makes or issues a dividend or other distribution payable in securities or other property (other than cash or additional shares of Pinnacle Corp. Stock), then in order to exercise the Put Right, the Plans must deliver to Northwest the Plan Shares as to which the Put Right is being exercised together with such securities or other property previously received in respect of each such Plan Share in such dividend or other distribution.

Section 8.7. Effect of Acceleration of Credit Facility.  Notwithstanding any other provision of this Article VIII, if at any time an acceleration of Northwest’s obligations occurs for any reason under the Credit Agreement, (a) Fiduciary Counselors may elect to exercise the Put Option and the applicable Put Closing Date will be the applicable Put Exercise Date and (b) if

-29-

such acceleration under the Credit Agreement occurs after a Put Exercise Date has occurred but before the applicable Put Closing Date, the Put Closing Date shall be the date on which Northwest’s obligations under the Credit Agreement are accelerated.

Section 8.8.    Guarantee.  Guarantor unconditionally and irrevocably guarantees to Fiduciary Counselors, for the benefit of the Plans, the prompt and complete performance by Northwest when due of Northwest’s obligations pursuant to this Article VIII and such guarantee will remain in full force and effect until the Put Option has expired with respect to all of the Plan Shares in accordance with Section 8.5 above; provided, however, in the event of the voluntary or involuntary bankruptcy of Northwest, the foregoing guarantee shall survive for the duration of any applicable preference period, notwithstanding any other provision of this guarantee.

ARTICLE IX

REGISTRATION RIGHTS

Section 9.1.    Initial Public Offering.  (a)  Timing.  (i)  Subject to Section 9.1(a)(ii), Pinnacle Corp. will not undertake an IPO without the express written consent of Northwest, and such consent will be at Northwest’s sole discretion.  Northwest will have the sole and exclusive right to demand that Pinnacle Corp. undertake an IPO at any time from the date hereof until the earlier of (i) July 1, 2006 or (ii) the occurrence of an Early Termination Event (such earlier date, the “Plan IPO Demand Trigger Date”).  Upon such a demand by Northwest and at Northwest’s direction, Pinnacle Corp. will use its reasonable best efforts to cause the IPO Registration Statement or another registration statement used for the IPO to become effective, and such effectiveness will be accelerated to a date and time specified by Northwest, and to cause the IPO to occur in accordance with Northwest’s request.  The IPO will not include any shares of Pinnacle Corp. Stock to be sold for the account of Pinnacle Corp. without Northwest’s prior written consent.

(ii)           If Pinnacle Corp. has not consummated an IPO by the Plan IPO Demand Trigger Date, then the Plans as well as Northwest may at any time following such Plan IPO Demand Trigger Date demand that Pinnacle Corp. commence an IPO and cause it to occur in accordance with Section 9.1(a)(i) above (i.e., upon such demand by the Plans and at the direction of the Plans, Pinnacle Corp. will commence an IPO and cause it to occur in accordance with Section 9.1(a)(i) above).

(b)           Registration of Pinnacle Corp. Shares in IPO.  The number of Pinnacle Corp. Shares to be registered by Pinnacle Corp. in an IPO will not be less than the number of Pinnacle Corp. Shares indicated by the managing underwriter of the IPO as necessary to effect an optimal offering of such Pinnacle Corp. Shares.  The Plans will sell Plan Shares in the IPO at the direction of Northwest ratably with Northwest’s sale of Pinnacle Corp. Shares held by Northwest in the aggregate amount necessary to achieve such optimal size.  The Plans may at the discretion of Fiduciary Counselors (but will not be required) to sell Plan Shares in excess of their pro rata share of such number requested by the managing underwriter to achieve such optimal size.  However, in the event that the aggregate number of Pinnacle Corp. Shares sought to be sold by Northwest and the Plans collectively in the IPO exceeds the number of Pinnacle Corp. Shares that the managing underwriter of the IPO advises in writing can be sold without having an

-30-

adverse effect on the price or distribution of the securities offered in such IPO, then Pinnacle Corp. will reduce the number of Pinnacle Corp. Shares to be included in the IPO by Northwest and the Plans on a pro rata basis based on the number of Pinnacle Corp. Shares held by Northwest and each of the Plans until the number of Pinnacle Corp. Shares to be sold by Northwest and the Plans collectively would not, in the opinion of the managing underwriter of the IPO, have an adverse effect on the price or distribution of the securities offered in the IPO.  Any Plan Shares with respect to which Fiduciary Counselors has, on behalf of the Plans, exercised the Put Option, and which have not yet been purchased by Northwest pursuant to such exercise, will, at the request of Northwest, be included as a portion of the Plan Shares sought to be sold in the IPO as contemplated by and in accordance with Section 8.3.

(c)           Proceeds from IPO.  The Plans will be entitled to retain all of the net proceeds from the sale of the Plan Shares in the IPO.  If the net proceeds to the Plans from the sale of any Plan Shares in connection with the IPO are less than the aggregate Floor Price of such Plan Shares, Northwest will be obligated at a time no later than the date of closing of such IPO to remit to the Plans immediately available funds which represent the amount by which, with respect to such Plan Shares actually sold, such net proceeds are less than the aggregate Floor Price of such Plan Shares.

(d)           Selection of Financial Advisers for IPO.  Northwest will have the exclusive right to select the investment bank(s) and manager(s) to administer the IPO on behalf of Pinnacle Corp. whether the IPO is initiated upon a demand by Northwest or by the Plans.  Northwest will consult with Fiduciary Counselors prior to finalizing any change with respect to the managing underwriter(s) selected by Northwest on behalf of Pinnacle Corp.  Fiduciary Counselors may on behalf of the Plans engage an additional independent investment bank and one legal counsel reasonably acceptable to Northwest to provide advice to the Plans in connection with the IPO and subsequent disposition of the Plan Shares by the Plans thereunder.  Northwest agrees to pay the reasonable fees and expenses of such advisor for such advisory services, and the reasonable fees and expenses of such legal counsel for its services, rendered to Fiduciary Counselors and the Plans in connection with the IPO.

(e)           Over-Allotment Allocation.  If an IPO is conducted that contemplates a sale of all of the Pinnacle Corp. Shares to the public (assuming full exercise by the underwriters of their over-allotment option in the IPO), then, at Fiduciary Counselors’s option, the underwriters’ over-allotment option may be covered exclusively by Pinnacle Corp. Shares held by Northwest.

Section 9.2. Shelf Registration Statements.  (a)  If Pinnacle Corp. is permitted to register securities under the Securities Act on Form S-3 or any similar or successor short form registration statement, then upon the request of either Fiduciary Counselors, on behalf of the Plans, or Northwest, Pinnacle Corp. will cause to be filed and use commercially reasonable efforts to have declared effective as soon as reasonably practicable thereafter, one or more shelf registration statements pursuant to Rule 415 under the Securities Act (each a “Shelf Registration Statement,” and collectively, the “Shelf Registration Statements”).  Such Shelf Registration Statements will cover all of the Plan Shares and any Pinnacle Corp. Shares retained by Northwest following the IPO.

-31-

(b)           Each Shelf Registration Statement will be on the appropriate form and will comply as to form in all material respects with the requirements of the Securities Act and the rules and regulations promulgated thereunder, permitting registration of such Pinnacle Corp. Shares for resale by Northwest and the Plans in the manner designated by them.  Each Shelf Registration Statement filed after the filing of the first Shelf Registration Statement filed pursuant to Section 9.2(a) of this Agreement will constitute a post-effective amendment to such previously filed Shelf Registration Statement under Rule 429 under the Securities Act.

Section 9.3. Maintenance of Effectiveness.  (a)  Pinnacle Corp. will use its reasonable best efforts to keep any Shelf Registration Statement required by Section 9.2(a) continuously effective, supplemented and amended to the extent necessary to ensure that:

(i)            it is available for sales of Pinnacle Corp. Shares by Northwest and the Plans in accordance with Section 9.2(a) above; and

(ii)           it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the SEC as announced from time to time, until such time as there are no more Plan Shares or shares held by Northwest (such period, the “Effective Period”).

(b)           Neither the Plans nor Northwest may include any Pinnacle Corp. Shares in any Shelf Registration Statement pursuant to this Agreement unless and until it furnishes to Pinnacle Corp. in writing, within 20 days after receipt of a request therefor (and the Plans and Northwest agree to provide), the information with respect to itself and its plan of distribution as specified in Item 507 or 508 of Regulation S–K, as applicable, of the Securities Act for use in connection with such Shelf Registration Statement or any prospectus or preliminary prospectus included therein.  Each of the Plans and Northwest that is selling Pinnacle Corp. Shares pursuant to such Shelf Registration Statement agrees to promptly furnish to Pinnacle Corp. additional information as to itself and its plan of distribution required to be disclosed in order to make the information previously furnished by it to Pinnacle Corp. not materially misleading.

(c)           Following the effectiveness of any Shelf Registration Statement, Pinnacle Corp. agrees to request from each of the Plans and Northwest no less often than once every six months, a certification stating the number of unregistered Pinnacle Corp. Shares that each such Plan and/or Northwest expects to offer or sell within one year of the date of such certification.  If the number of Pinnacle Corp. Shares that the Plans and Northwest collectively certify to Pinnacle Corp. as the number of Pinnacle Corp. Shares the Plans and Northwest reasonably expect to sell within one year of the date of such certification exceeds the amount registered on all Shelf Registration Statements previously filed and not yet sold, Pinnacle Corp. will as promptly as practicable file a new Shelf Registration Statement increasing the number of Pinnacle Corp. Shares registered for sale by the Plans and Northwest by the number so certified by them.

Section 9.4.    Incidental Registration.  (a)  Right to Include Shares of Common Stock.  If Pinnacle Corp. at any time after the date hereof proposes to register any of its common stock under the Securities Act (other than a registration on Form S–4 or S–8, or any successor or other forms promulgated for similar purposes), whether or not for sale for its own account, in a manner which would permit registration of Plan Shares or Pinnacle Corp. Shares held by Northwest for sale to the public under the Securities Act, it will, at each such time, give prompt written notice

-32-

to Northwest, Fiduciary Counselors and the Plans of its intention to do so and of Northwest’s and the Plans’ rights under this Section 9.4.  Upon the written request of either Northwest or Fiduciary Counselors made within 15 days after the receipt of any such notice (which request will specify the number of Plan Shares intended to be disposed of by the Plans or the number of Pinnacle Corp. Shares to be disposed of by Northwest, as the case may be), Pinnacle Corp. will effect the registration under the Securities Act of the Pinnacle Corp. Shares which Pinnacle Corp. has been so requested to register by Northwest and/or Fiduciary Counselors, to the extent requisite to permit the disposition of such Pinnacle Corp. Shares so to be registered; provided that if such registration involves an underwritten offering, the Plans must sell the Plan Shares to the underwriters on the same terms and conditions as apply to Pinnacle Corp. and/or Northwest, with such differences, including any with respect to indemnification and liability insurance, as may be customary or appropriate in combined primary and secondary offerings; provided further that in no event will Fiduciary Counselors or the Plans be required to provide any representations and warranties or indemnities as to information relating to Northwest, Pinnacle Corp. or Pinnacle Airlines or any of their respective Affiliates.  If a registration requested pursuant to this Section 9.4 involves an underwritten public offering, any seller of Pinnacle Corp. Shares requesting to be included in such registration may elect, in writing prior to the effective date of the registration statement filed in connection with such registration, not to register such securities in connection with such registration.

(b)           Termination of Proposed Registration.  If, at any time after giving written notice of its intention to register any securities under the Securities Act in accordance with the provisions of Section 9.4 hereof and prior to the effective date of the registration statement filed in connection with such registration, Pinnacle Corp. determines for any reason not to proceed with the proposed registration of the securities to be sold by it, Pinnacle Corp. may, at its election, give written notice of such determination to Northwest and the Plans, and, thereupon, will be relieved of its obligation to register any Pinnacle Corp. Shares in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith).

(c)           Registration Statement Form; Priority in Incidental Registrations.  (i)  If any registration requested pursuant to this Section 9.4 and which is proposed by Pinnacle Corp. to be effected by the filing of a registration statement on Form S-3 (or any successor or similar short-form registration statement) and involves an underwritten offering, and if the managing underwriter of such offering advises Pinnacle Corp. that, in its opinion, the use of another form of registration statement is of material importance to the success of the proposed offering, then such registration will be effected on such other form.

(ii)           If a registration pursuant to this Section 9.4 involves an underwritten offering and the managing underwriter advises Pinnacle Corp. in writing that, in its opinion, the number of securities requested to be included in such registration exceeds the number which can be sold in such offering, so as to be likely to have an adverse effect on the price, timing or distribution of the securities offered in such offering as contemplated by Pinnacle Corp., then Pinnacle Corp. will include in such offering the number of Pinnacle Corp. Shares requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without having the adverse effect referred to above, such amount to be allocated first, to the shares of Pinnacle Corp. Stock proposed to be sold by Pinnacle Corp. for its own account, and second, pro rata

-33-

among Northwest and the Plans on the basis of the relative number of securities then held by such party (provided that any securities thereby allocated to either of Northwest or the Plans that exceed such party’s request will be reallocated among the remaining parties in a like manner if the respective requests of each of the Plans and Northwest have been satisfied).

Section 9.5. Registration on Demand.  (a)  In addition to any demand rights the Plans may have under Section 9.1 hereof, in the event that either (i) after the IPO the Plans hold Plan Shares valued (based on the IPO price per share) at $50,000,000 or more, or (ii) an Early Termination Event occurs, the Plans will have the right to demand one registration under the Securities Act of all or part of such remaining Plan Shares (unless a shelf registration statement has been or is being effected in accordance with Section 9.2).  In addition Northwest will have the right to demand one registration under the Securities Act of all or part of such remaining Pinnacle Corp. Shares held by it following the IPO.  At any time (X) following the satisfaction of the conditions contained in clause (i) or (ii) of the previous sentence, upon the written request of Fiduciary Counselors or (Y) following the IPO, upon the written request of Northwest, in the case of either (X) or (Y) requesting that Pinnacle Corp. effect the registration under the Securities Act of all or part of the Pinnacle Corp. Shares then held by the requesting party and specifying the amount and intended method of disposition thereof, Pinnacle Corp. will use its reasonable best efforts to effect the registration under the Securities Act of such Pinnacle Corp. Shares.

(b)           Notwithstanding the foregoing, Pinnacle Corp. will not be obligated to file a registration statement relating to any registration request pursuant to this Section 9.5 within a period of six months after the effective date of any other registration statement relating to any registration request pursuant to this Agreement which was not effected on Form S-3 (or any successor or similar short-form registration statement) or relating to any registration effected under Section 9.1, or, if with respect to such registration statement, the managing underwriter, the SEC, the Securities Act or the rules and regulations thereunder, or the form on which the registration statement is to be filed, would require the conduct of an audit other than the regular audit conducted by Pinnacle Corp. at the end of its fiscal year, in which case the filing may be delayed until the completion of such regular audit.

(c)           A registration requested pursuant to this Section 9.5 will not be deemed to have been effected unless it has become effective; provided that if, within 180 days after it has become effective, the offering of the Pinnacle Corp. Shares pursuant to such registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court, such registration will be deemed not to have been effected, in which case, the requesting party shall be deemed to have not made a registration request under this Section 9.5 with respect to such registration.

Section 9.6.    Lock-Up.  Each of Northwest and the Plans will not effect any sales of Pinnacle Corp Shares during the 14 days prior to and up to a 180 day period beginning on the effective date of a registration statement used for the IPO if and to the extent requested in writing (with reasonable prior notice) by the managing underwriter of the IPO (except as part of the IPO).  In the case of any other underwritten public offering in accordance with this Article IX in which any of Northwest or the Plans or Pinnacle Corp. is participating, to the extent requested in writing (with reasonable prior notice) by the managing underwriter of such underwritten public

-34-

offering, each of Northwest and the Plans agrees that it shall not effect any sales of Pinnacle Corp Shares from 14 days prior to and up to a 90 day period beginning on the date of consummation of such underwritten public offering (except as part of such registration).

Section 9.7. Registration Procedures.  In connection with Pinnacle Corp.’s obligations pursuant to this Article IX (including without limitation Section 9.1, Section 9.2, Section 9.4 and Section 9.5) to effect such registrations and/or offerings to permit the sale of Pinnacle Corp. Shares in accordance with the intended method or methods of disposition thereof, and pursuant thereto Pinnacle Corp. will pay all applicable Registration Expenses and will as soon as possible:

(a)           prepare and file with the SEC a registration statement or registration statements on any appropriate form under the Securities Act available for the sale of Pinnacle Corp. Shares by Northwest or the Plans, or both, in accordance with the intended method or methods of distribution thereof, and use its reasonable best efforts to cause each such registration statement or statements to become effective and remain effective and usable for resale of Pinnacle Corp. Shares during the period that such registration statement is required to be effective and usable as provided herein, use its reasonable best efforts to not take any action that would cause such registration statement to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and cause such registration statement and the related prospectus and any amendment or supplement thereto, as of the effective date of such registration statement, amendment or supplement, to comply in all material respects with any requirements of the Securities Act and the rules and regulations promulgated thereunder; provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto (excluding documents that would be incorporated or deemed to be incorporated therein by reference), Pinnacle Corp. will furnish to (i) each of Northwest and the Plans holding Pinnacle Corp. Shares covered by such registration statement and/or prospectus, (ii) not more than one counsel chosen by Northwest, which counsel is reasonably acceptable to the Plans (“Special Counsel”) and (iii) the managing underwriter(s), if any, copies of all such documents proposed to be filed, which documents will be subject to the review of Northwest, the Plans, such Special Counsel and such underwriters, and Pinnacle Corp. will not file any such registration statement or amendment thereto or any prospectus or any supplement thereto (excluding such documents that, upon filing, will be incorporated or deemed to be incorporated by reference therein) containing any information about any of Northwest, the Plans or the managing underwriter, if any, reasonably objects.

(b)           Prepare and file with the SEC such amendments and post-effective amendments to each registration statement as may be necessary to keep such registration statement effective as provided herein; cause the related prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement as so amended or in such prospectus as so supplemented.

(c)           Notify the selling Plans, Northwest and any managing underwriters (and, in each case, counsel therefor if appropriate notice information has been provided reasonably in advance

-35-

to Pinnacle Corp.) promptly, and (if requested by any such Person) confirm such notice in writing:

(i)            when a prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a registration statement or any post-effective amendment, when the same has become effective;

(ii)           of any request by the SEC or any other Governmental Authority for amendments or supplements to a registration statement or related prospectus or for additional information;

(iii)          of the issuance by the SEC or any other Governmental Authority of any stop order, injunction or other order suspending the effectiveness of a registration statement or the initiation or threatening of any proceedings for that purpose;

(iv)          if at any time the representations and warranties of Pinnacle Corp. contained in any agreement entered into by Pinnacle Corp. in connection with the offering (including any underwriting agreement) cease to be true and correct in any material respect;

(v)           of the receipt by Pinnacle Corp. of any notification with respect to the suspension of the qualification or exemption from qualification of any of Pinnacle Corp. Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;

(vi)          of the occurrence of any event, circumstance or condition that makes any statement made in such registration statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in a registration statement, prospectus or any such document so that, in the case of the registration statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, in the case of the prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and

(vii)         of Pinnacle Corp.’s reasonable determination that a post-effective amendment to a registration statement would be appropriate.

(d)           Use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any Pinnacle Corp. Shares for sale in any jurisdiction as soon as possible.

(e)           If requested by the managing underwriters, if any, or Northwest:

(i)            promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriters, if any, Northwest and the Plans agree should be included therein as may be required by applicable Law; and

-36-

(ii)           make all required filings of such prospectus supplement or such post-effective amendment as soon as practicable after Pinnacle Corp. has received notification of the matters to be incorporated in such prospectus supplement or post-effective amendment;

provided, however, that Pinnacle Corp. will not be required to take any actions under this Section 9.7(e) that are not, in the opinion of Pinnacle Corp.’s counsel, in compliance with applicable Law.

(f)            Furnish to each of Northwest and/or each of the selling Plans named in any registration statement and each managing underwriter, if any, without charge, such number of copies of the registration statement and any post-effective amendment thereto (but excluding schedules, all documents incorporated or deemed incorporated therein by reference and all exhibits, unless requested in writing by such party or such underwriter), each prospectus, including each preliminary prospectus, and any amendment or supplement thereto and such other documents as such party or managing underwriter may reasonably request in order to facilitate the public sale or other disposition of Pinnacle Corp. Shares; Pinnacle Corp. hereby consents to the use of the prospectus, including each preliminary prospectus, by each of the Plans and Northwest and each underwriter of an underwritten offering, if any, in connection with the offering and sale of Pinnacle Corp. Shares covered by the prospectus or the preliminary prospectus at such times and in such manner as permitted by this Agreement.

(g)           Prior to any public offering of Pinnacle Corp. Shares, to register or qualify or cooperate with Northwest and the selling Plans, the underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Pinnacle Corp. Shares for offer and sale under the securities or blue sky Laws of such jurisdictions within the United States as any seller of Pinnacle Corp. Shares or underwriter reasonably requests in writing; use its reasonable best efforts to keep such registration or qualification (or exemption therefrom) effective during the period the applicable registration statement is required to be kept effective and do any and all other acts or things necessary or advisable to enable the disposition in each such jurisdiction of Pinnacle Corp. Shares covered by the applicable registration statement; provided, however, that Pinnacle Corp. will not be required to (i) qualify to do business in any jurisdiction where it is not then so qualified or (ii) take any action that would subject it to taxation or service of process in any such jurisdiction where it is not then so subject.

(h)           Use its reasonable best efforts to cause Pinnacle Corp. Shares covered by the applicable Registration Statement to be registered with or approved by such other governmental agencies or authorities within the United States except as may be required solely as a consequence of the nature of business conducted by Northwest or any of the Plans, in which case Pinnacle Corp. will cooperate in all reasonable respects with the filing of such registration statement and the granting of such approvals as may be necessary to enable the seller or sellers thereof or the underwriters, if any, to consummate the disposition of such Pinnacle Corp. Shares.

(i)            Cooperate with each of Northwest and the selling Plans and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Pinnacle Corp. Shares to be sold and enable such Pinnacle Corp. Shares to be in such denominations and registered in such names as Northwest, the selling Plans and the managing

-37-

underwriters, if any, will request at least two Business Days prior to any sale of Pinnacle Corp. Shares.

(j)            Prepare a supplement or post-effective amendment to each registration statement or a supplement to the related prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Pinnacle Corp. Shares being sold thereunder, such prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(k)           Use its reasonable best efforts to cause all Pinnacle Corp. Shares covered by such registration statement to be:

(i)            listed on each securities exchange, if any, on which similar securities issued by Pinnacle Corp. are then listed or, if no similar securities issued by Pinnacle Corp. are then so listed, on the New York Stock Exchange or another national securities exchange as soon as the securities qualify to be so listed; or

(ii)           authorized to be quoted on the NASDAQ, as soon as the securities qualify to be so quoted.

(l)            As needed, (i) engage an appropriate transfer agent and provide the transfer agent with printed certificates for Pinnacle Corp. Shares in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for Pinnacle Corp. Shares.

(m)          Make available for reasonable inspection during normal business hours by Northwest, the Plans and any underwriter participating in any disposition of Pinnacle Corp. Shares, and any attorney or accountant retained by any such Person, all financial and other records, pertinent corporate documents and properties of Pinnacle Corp. and its subsidiaries, and cause the officers, directors and employees of Pinnacle Corp. and its subsidiaries to supply all information reasonably requested by Northwest, the Plans, any such underwriter, attorney or accountant in connection with such registration statement; provided, however, that any records, information or documents that are designated by Pinnacle Corp. in writing as confidential at the time of delivery of such records, information or documents will be kept confidential by such Persons unless:

(i)            such records, information or documents are in the public domain or otherwise publicly available;

(ii)           disclosure of such records, information or documents is required by court or administrative order; provided, that such underwriter notifies Pinnacle Corp. of any such requirement and cooperates with Pinnacle Corp. in seeking a protective or restraining order limiting such disclosure; or

(iii)          disclosure of such records, information or documents, upon reasonable advice of counsel to such Person, is otherwise required by Law (including pursuant to the requirements of the Securities Act) or the rules or regulations of any securities exchange or NASDAQ.

-38-

(n)           Within a reasonable time prior to the filing of any registration statement, any prospectus, any amendment to a registration statement or amendment or supplement to a prospectus, in each case containing information regarding any of Northwest, Fiduciary Counselors and/or the Plans, provide copies of such document to such Person and/or the managing underwriter(s) of an underwritten offering, if any; fairly consider such reasonable changes in any such document prior to the filing thereof as such Person may request and not file any such document in a form to which any such Person reasonably objects; and make such of the representatives of Pinnacle Corp. as will be reasonably requested by any such Person available for discussion of such document.

(o)           Comply with all applicable rules and regulations of the SEC and make generally available to its security holders earning statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 calendar days after the end of any 12-month period (or 90 calendar days after the end of any 12–month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Pinnacle Corp. Shares are sold to underwriters in a firm commitment or reasonable best efforts underwritten offering, or (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of Pinnacle Corp., after the effective date of a registration statement, which statements will cover such 12-month period.

(p)           Pinnacle Corp. will enter into such customary agreements (including in the event of an underwritten offering, an underwriting agreement negotiated on behalf of Pinnacle Corp. by Northwest in form, scope and substance as is customary in underwritten offerings) and take all such other commercially reasonable and customary actions in connection therewith (including taking those actions directed by Northwest, the Plans or, in the event of an underwritten offering, those reasonably requested by the managing underwriters) in order to facilitate the disposition of such Pinnacle Corp. Shares and in such connection, but only where an underwriting agreement is entered into in connection with an underwritten offering:

(i)            make such representations and warranties to the underwriters, Northwest and the Plans, with respect to the businesses of Pinnacle Corp. and its subsidiaries, the registration statement, prospectus and documents incorporated by reference or deemed incorporated by reference therein, if any, and any other customary representations and warranties, in each case, in form, substance and scope as are customarily made by issuers in secondary offerings to underwriters in underwritten offerings and confirm the same if and when requested;

(ii)           obtain opinions of its counsel and updates thereof, which counsel and opinions (in form, scope and substance) will be reasonably satisfactory to the managing underwriters, if any, addressed to each of the underwriters, Northwest and the Plans covering the matters customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by underwriters, Northwest or the Plans;

(iii)          use commercially reasonable efforts (provided appropriate representation letters are delivered by the underwriters) to obtain “comfort” letters and updates thereof from its independent certified public accountants (and, if necessary, any other certified public accountants of any of its subsidiaries or of any business acquired by Pinnacle Corp. for which financial statements and financial data is, or is required to be, included in the registration

-39-

statement), addressed to each of the underwriters, Northwest and the Plans, such letters to be in customary form and covering matters of the type customarily covered in “comfort” letters in connection with underwritten offerings;

(iv)          use its reasonable best efforts to the extent reasonably requested by the managing underwriters to facilitate the distribution and sale of any Pinnacle Corp. Shares to be offered, including causing Pinnacle Corp.’s management to be made available for, and assist in, the marketing and disposition of such Pinnacle Corp. Shares in the manner and to the extent directed by Northwest and the underwriters including participation by management in customary road shows, investor meetings and conferences and other similar presentations; and

(v)           deliver such documents and certificates as may be reasonably requested by the managing underwriters, if any, Northwest or the Plans to evidence the continued validity of the representations and warranties of Pinnacle Corp. and its subsidiaries made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in the underwriting agreement.

The foregoing actions will be taken in connection with each closing under such underwriting agreement as and to the extent required thereunder.

Section 9.8.    Plan Adherence to Underwriting Arrangements.  If a requested registration pursuant to this Article IX involves an underwritten offering, the Plans agree to enter into the customary underwriting agreement negotiated by Northwest on behalf of Pinnacle Corp. in accordance with Section 9.7(p) above; such underwriting agreement (i) will permit the Plans to receive and rely upon any officer’s certificates or opinions delivered by or on behalf of Pinnacle Corp. to the underwriters thereunder, and (ii) may include indemnification provisions in favor of underwriters and other persons, and may include such other obligations of the Plans as are customarily applicable to a selling stockholder, including the obligation to deliver customary legal opinions.  The Plans agree to take such other actions in connection with the offering as Northwest or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Plan Shares, including the execution and delivery of share certificates and stock powers representing the Plan Shares to be disposed of in the offering.  The Plans will sell the Plan Shares in accordance with such underwriting agreement, on the same economic terms that shares of Pinnacle Corp. Shares held by Northwest are sold in the offering, subject to Article VIII of this Agreement.

Section 9.9. Indemnification.  (a)  Indemnification by Pinnacle Corp.  In the event of any registration of any Pinnacle Corp. Shares under the Securities Act pursuant to this Agreement, Pinnacle Corp. will, and it hereby does, indemnify and hold harmless, the seller of any Pinnacle Corp. Shares covered by such registration statement, each affiliate of such seller and their respective directors and officers or general and limited partners (including any director, officer, affiliate, employee, agent and controlling Person of any of the foregoing), each other Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any, who controls such seller or any such underwriter within the meaning of the Securities Act (collectively, the “Section 9.9(a) Indemnified Parties”), against any and all losses, claims, damages or liabilities, joint or several, and expenses (including reasonable attorney’s fees and reasonable expenses of investigation) to which such Section 9.9(a)

-40-

Indemnified Party may become subject under the Securities Act, common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof, whether or not such Indemnified Party is a party thereto) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement (including any amendment or supplement thereto) under which such securities were registered under the Securities Act, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading, and Pinnacle Corp. will reimburse such Section 9.9(a) Indemnified Party for any legal or any other expenses reasonably incurred by it in connection with investigating or defending against any such loss, claim, liability, action or proceeding, as such expenses are incurred; provided that Pinnacle Corp. will not be liable to any Section 9.9(a) Indemnified Party in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or amendment or supplement thereto or in any such preliminary, final or summary prospectus in reliance upon and in conformity with written information furnished to Pinnacle Corp. with respect to such seller through an instrument duly executed by such seller specifically stating that it is for use in the preparation thereof; and provided, further, that Pinnacle Corp. will not be liable to any Person who participates as an underwriter in the offering or sale of Pinnacle Corp. Shares or any other Person, if any, who controls such underwriter within the meaning of the Securities Act, under the indemnity agreement in this Section 9.9 with respect to any preliminary prospectus or the final prospectus or the final prospectus as amended or supplemented, as the case may be, to the extent that any such loss, claim, damage or liability of such underwriter or controlling Person results from the fact that such underwriter sold Pinnacle Corp. Shares to a person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the final prospectus or of the final prospectus as then amended or supplemented, whichever is most recent, if Pinnacle Corp. has previously furnished copies thereof to such underwriter.  For purposes of the last proviso to the immediately preceding sentence, the term “prospectus” will not be deemed to include the documents incorporated therein by reference, and no Person who participates as an underwriter in the offering or sale of Pinnacle Corp. Shares or any other Person, if any, who controls such underwriter within the meaning of the Securities Act, will be obligated to send or give any supplement or amendment to any document incorporated by reference in any preliminary prospectus or the final prospectus to any person other than a person to whom such underwriter had delivered such incorporated document or documents in response to a written request therefor.  Such indemnity will remain in full force and effect regardless of any investigation made by or on behalf of such seller or any Section 9.9(a) Indemnified Party, or any of their respective affiliates, directors, officers or controlling persons, and will survive the transfer of such securities by such seller.

(b)           Indemnification by Sellers and Underwriters.  Pinnacle Corp. may require, as a condition to including any Pinnacle Corp. Shares in any registration statement filed in accordance with this Article IX, that Pinnacle Corp. will have received an undertaking reasonably satisfactory to it from each prospective seller of such Pinnacle Corp. Shares or any underwriter to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 9.9(a)) Pinnacle Corp. and all other prospective sellers (collectively, the

“Section 9.9(b) Indemnified Parties” and, together with the Section 9.9(a) Indemnified Parties, the “Indemnified Parties”) with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement, if such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to Pinnacle Corp. with respect to such seller through an instrument duly executed by such seller or underwriter specifically stating that it is for use in the preparation of such registration statement, preliminary, final or summary prospectus or amendment or supplement, or a document incorporated by reference into any of the foregoing.  Such indemnity will remain in full force and effect regardless of any investigation made by or on behalf of any Section 9.9(b) Indemnified Party, or any of its affiliates, directors, officers or controlling Persons and will survive the transfer of such securities by such seller.  In no event will the liability of any seller of Pinnacle Corp. Shares hereunder be greater in amount than the dollar amount of the proceeds received by such seller of Pinnacle Corp. Shares upon the sale of the Pinnacle Corp. Shares giving rise to such indemnification obligation.

(c)           Notices of Claims, Etc.  Promptly after receipt by an Indemnified Party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 9.9, such Indemnified Party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9.9, give written notice to the latter of the commencement of such action; provided that the failure of the Indemnified Party to give notice as provided herein will not relieve the indemnifying party of its obligations under the preceding subdivisions of this Section 9.9, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice.  In case any such action is brought against an Indemnified Party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the indemnifying party will not be liable to such Indemnified Party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation.  Notwithstanding the indemnifying party’s election to appoint counsel to represent an Indemnified Party in an action, such Indemnified Party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent such Indemnified Party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both such Indemnified Party and the indemnifying party and such Indemnified Party shall have reasonably concluded that there may be legal defenses available to it or other Indemnified Parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to such Indemnified Party to represent such Indemnified Party within a reasonable time after notice of the institution of such action, or (iv) the indemnifying party shall authorize such Indemnified Party to employ separate counsel at the expenses of the indemnifying party.  No indemnifying party will consent to entry of any judgment or enter into any settlement which (i) does not include as an unconditional term thereof, the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation and

-42-

(ii) includes a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any Indemnified Party.

(d)           Contribution.  If the indemnification provided for in this Section 9.9 from the indemnifying party is unavailable to an Indemnified Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such Indemnified Party, will contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and Indemnified Parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations.  The relative fault of such indemnifying party and Indemnified Parties will be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or Indemnified Parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.  The amount paid or payable by a party under this Section 9.9 as a result of the losses, claims, damages, liabilities and expenses referred to above will be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 9.9 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph.  Notwithstanding the provisions of this Section 9.9(d), no seller of Pinnacle Corp. Shares (other than a Person that participates as an underwriter in the offering or sale of Pinnacle Corp. Shares) shall be required to contribute any amount in excess of the amount by which the dollar amount of the proceeds received by such seller from the sale of such Pinnacle Corp. Shares (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such seller has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no Person that participates as an underwriter in the offering or sale of Pinnacle Corp. Shares shall be required to contribute any amount in excess of the amount by which the total price at which the Pinnacle Corp. Shares underwritten by it and distributed to investors were offered to investors exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

(e)           Other Indemnification.  Indemnification similar to that specified in the preceding subdivisions of this Section 9.9 (with appropriate modifications) will be given by Pinnacle Corp. and each seller of Pinnacle Corp. Shares with respect to any required registration or other qualification of securities under any federal or state Law or regulation or governmental authority other than the Securities Act.

-43-

(f)            Non–Exclusivity.  The obligations of the parties under this Section 9.9 will be in addition to any liability which any party may otherwise have to any other party.

Section 9.10. Rule 144.  Pinnacle Corp. covenants to the holders of Pinnacle Corp. Shares that to the extent Pinnacle Corp. shall be required to do so under the Exchange Act, it shall timely file the reports required to be filed by under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the SEC under the Securities Act) and the rules and regulations adopted by the SEC thereunder, and shall take such further action as any holder of Pinnacle Corp. Shares may reasonably request, all to the extent required from time to time to enable such holder to sell Pinnacle Corp. Shares without registration under the Securities Act within the limitations provided by Rule 144 under the Securities Act, as such rule may be amended from time to time, or any similar or successor rule or regulation hereafter adopted by the SEC.  Upon the request of any holder of Pinnacle Corp. Shares in connection with that holder’s sale pursuant to Rule 144, Pinnacle Corp. shall deliver to such holder a written statement as to whether it has complied with such requirements.

Shares outstanding as of the time of the formation of the IPO Corp.  “Additional Consideration” shall mean (i) in the case of Northwest, a promissory

-50-

note of IPO Corp. payable to the order of Northwest (the “IPO Note”) and (ii) in the case of the Plans, IPO Common Shares.

(c)           At the time of the formation of IPO Corp., each of Northwest and the Plans will cause IPO Corp. to, and Pinnacle Corp. will and will cause Pinnacle Airlines (and any Affiliate) to, enter into a Tax Sharing Agreement substantially in the form of Exhibit D attached hereto with Northwest and NWA Corp.

(ii)           The liability of each of IPO Corp. and Pinnacle Corp. pursuant to this Section 11.8(d) will not be discharged or affected in any way by (A) the granting of time or other indulgence or concession to any of Pinnacle Airlines or its Affiliates under the IPO Tax Sharing Agreement, (B) any amendment to the IPO Tax Sharing Agreement, (C) any compromise, release, abandonment, waiver, variation or relinquishment of the rights of any of Northwest or its Affiliates against any of Pinnacle Airlines or its Affiliates under the IPO Tax Sharing Agreement or by any omission to enforce such rights, (D) any present or future Law, regulation or order of any jurisdiction or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any obligation of Pinnacle Airlines or its Affiliates under the IPO Tax Sharing Agreement, or (E) any other act, omission, dealing or matter whatsoever (including without limitation, any change in the certificate of incorporation or bylaws of any of Pinnacle Airlines or its Affiliates or the liquidation, dissolution, reorganization or merger of any of Pinnacle Airlines or its Affiliates) that would or might release either of IPO Corp. or Pinnacle Corp. from any or all of its respective obligations under this Section 11.8(d).

(iii)          The guarantee provided under this Section 11.8(d) will be continuing and will remain in full force and effect until 120 days after the due performance, observance and fulfillment by Pinnacle Airlines and its Affiliates of all of their respective covenants, terms, provisions and conditions contained in the IPO Tax Sharing Agreement.  Notwithstanding the foregoing, if at any time after the termination of the guarantee provided under this Section 11.8(d) pursuant to the preceding sentence, any payment made under the IPO Tax Sharing Agreement is rescinded or must be returned due to the insolvency, bankruptcy or reorganization of any of Pinnacle Airlines or its Affiliates, the guarantee provided under this Section 11.8(d) will be reinstated.

(iv)          The guarantee provided under this Section 11.8(d) is in addition to and will not waive or prejudice or be waived or prejudiced by any other guarantee, indemnity, security, claim, right or remedy against any third party that any of Northwest or its Affiliates may have for the due performance of the obligations guaranteed hereby, including, without limitation, any rights

-51-

that any of Northwest or its Affiliates may have against any of Pinnacle Airlines or its Affiliates under the IPO Tax Sharing Agreement or at law or in equity.

(v)           Any amount not paid by Pinnacle Airlines or its Affiliates properly due under the IPO Tax Sharing Agreement and not recoverable from either IPO Corp. or Pinnacle Corp. on the basis of a guarantee (whether because of any legal limitation, disability or incapacity on the part of Pinnacle Airlines or its Affiliates or any other matter or thing, whether known to Northwest or its Affiliates or not) will be nevertheless recoverable from IPO Corp. or Pinnacle Corp. on the basis of a full indemnity.

(vi)          Each of IPO Corp. and Pinnacle Corp. will be primarily and jointly and severally liable with Pinnacle Airlines and its Affiliates to observe and perform the covenants, obligations and duties on the respective parts of Pinnacle Airlines and its Affiliates under the IPO Tax Sharing Agreement and to indemnify Northwest and its Affiliates in respect of all those matters for which Pinnacle Airlines and its Affiliates are responsible to Northwest and its Affiliates under the Plan Fiduciary Agreement and the Second Tax Sharing Agreement.  Northwest and its Affiliates may require each of IPO Corp. and Pinnacle Corp. to observe and perform all such covenants, obligations and duties as aforesaid and to indemnify Northwest and its Affiliates as aforesaid without first (or ever) taking proceedings against Pinnacle Airlines or its Affiliates or any other persons.  Each of IPO Corp. and Pinnacle Corp. waives any right that it may have to require any of Northwest or its Affiliates to proceed against any of IPO Corp., Pinnacle Corp. or Pinnacle Airlines, their respective Affiliates or any other person or to exhaust any security held by any of Northwest, its Affiliates or any other person, or to pursue any other remedy in its power.

(vii)         Each of IPO Corp and Pinnacle Corp. hereby waives and will have no right of subrogation with respect to any payment made pursuant to its guarantee under this Section 11.8(d).

(viii)        Each of IPO Corp. and Pinnacle Corp. hereby waives all presentment, demands for performance, protests, notices of nonperformance, protest, dishonor, amendment or acceptance of the guarantee, and any other formality with respect to any of the obligations of the guarantee under this Section 11.8(d).

Section 11.9.    Failure by Department of Labor to Issue Final Exemption.  (a)  Cure.  If the Department of Labor withdraws the proposed exemption referred to in Section 10.1(a)(ii) or fails to issue a final exemption pursuant to Section 408(a) of ERISA and Section 4975(c)(2) of the Code with respect to the transactions contemplated by this Agreement, Northwest shall be required to purchase all Plan Shares for cash as soon as practicable or otherwise cure as soon as practicable the failure to obtain such final exemption through any lawful means.  In the event that Northwest purchases the Plans Shares for cash, the per share purchase price of such Plan Shares will be the greater of the aggregate Floor Price applicable to such Plan Shares or the Market Value of such Plan Shares on the date of purchase by Northwest.

(b)           Indemnification.  (i)  As provided in Section 10.1(a)(ii) of this Agreement, Fiduciary Counselors will make decisions on behalf of the Plans regarding the acceptance of proposed contributions of Pinnacle Corp. Shares conditioned on, among other things, the

-52-

Department of Labor’s issuing a proposed exemption.  Northwest expects that the Department of Labor will finalize the proposed exemption after the Initial Contribution and when the proposed exemption becomes final it will apply retroactively to the Initial Contribution.  Northwest and Fiduciary Counselors agree that Fiduciary Counselors will perform its duties set forth in this Agreement and in the Plan Fiduciary Agreement even though the Department of Labor is expected not to have issued a final exemption on the date of the Initial Contribution.

In consideration of the foregoing, Northwest agrees to hold harmless and indemnify Fiduciary Counselors and its Affiliates against any and all claims, costs, damages, expenses, taxes and liabilities (including reasonable attorney’s fees and costs) that Fiduciary Counselors and its Affiliates may incur to any party (including, but not limited to, the Plans, any participant or beneficiary thereof, the Department of Labor or the Internal Revenue Service) solely as a result of the Department of Labor’s determination not to grant a final exemption with respect to a Contribution previously accepted by Fiduciary Counselors on behalf of the Plans following the Department of Labor’s issuance of a proposed exemption; provided, however, that the foregoing indemnification shall not apply to the extent that the Department of Labor determines not to grant a final exemption as a result of a materially false representation made by Fiduciary Counselors or any of its Affiliates to Northwest or to the Department of Labor in connection with the exemption sought by Northwest.

ARTICLE XII

CLOSING

Subject to the satisfaction or waiver of all conditions precedent contained in Section 10.1, the Closing will take place at the headquarters of Northwest, 0000 Xxxx Xxx Xxxxxxx, Xxxxx, Xxxxxxxxx 00000, on January 15, 2003, at a time mutually agreeable to the parties, or at such other time, date and place as the parties may agree in writing.  Concurrently with the Closing, the parties will cause the transactions contemplated by this Agreement which are to be effected at the Closing to be consummated.  Subject to the provisions of Article XIII, failure to consummate the transactions contemplated by this Agreement on the date and time and at the place determined pursuant to this Article XII will not result in the termination of this Agreement nor relieve any party of any obligation under this Agreement.

ARTICLE XIII

TERMINATION

Section 13.1. Termination.  This Agreement may be terminated at any time prior to Closing:

(a)           By mutual written consent of Northwest and Fiduciary Counselors;

(b)           By Northwest, if (i) there has been a material breach of any representation or warranty made by Fiduciary Counselors in this Agreement or (ii) Fiduciary Counselors fails to perform or comply in all material respects with any covenant or agreement contained in this Agreement required to be performed or complied with by Fiduciary Counselors, provided that, in

-53-

either case, such breach or noncompliance is not capable of being cured or has not been cured within 14 days after notice by Northwest specifying such breach or noncompliance;

(c)           By Fiduciary Counselors, if (i) there has been a material breach of any representation or warranty made by Northwest or Pinnacle Corp. in this Agreement or (ii) Northwest or Pinnacle Corp. fails to perform or comply in all material respects with any covenant or agreement contained in this Agreement required to be performed or complied with by Northwest or Pinnacle Corp., provided that, in either case, such breach or noncompliance is not capable of being cured or has not been cured within 14 days after notice by Fiduciary Counselors specifying such breach or noncompliance; or

(d)           By Pinnacle Airlines, Pinnacle Corp., Northwest or Fiduciary Counselors, if any Governmental Authority has issued an order, failed to take any action which would have the effect of declining to issue a Consent or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement, the Plan Fiduciary Agreement and the Second Tax Sharing Agreement, and such action will have become final and nonappealable.

Section 13.2. Effect of Termination.  Each party’s right to termination under this Article XIII is in addition to any other rights it may have under this Agreement or otherwise, and the exercise of a right of termination will not be an election of remedies.  If this Agreement is terminated in accordance with Section 13.1, all further obligations of the parties under this Agreement will terminate, except the provisions of Article XIV and Section 15.5, which will survive such termination indefinitely provided that, if this Agreement is terminated because of the willful breach of this Agreement by a party hereto, the other parties’ rights to pursue all legal remedies against the breaching party will survive such termination unimpaired.

ARTICLE XIV

REMEDIES

All of the representations and warranties made by Pinnacle Corp. and Northwest in this Agreement will, with respect to the Plan Shares contributed on the Closing Date or a Subsequent Contribution date and the Put Option relating to such Plan Shares, survive the date when such representations and warranties were made (whether the Closing Date or a Subsequent Contribution date) for a period of 24 months (except that the representations and warranties contained in Section 5.1(d), Section 5.1(e) and Section 5.1(f) will survive indefinitely), and no claims for the recovery of any damages may be asserted against any of the parties in respect thereto following the expiration of such survival period.  The Closing Certificates delivered pursuant to Article X will not survive beyond the Closing, other than in connection with claims for fraud.  The covenants and agreements of the parties contained in this Agreement will survive beyond the Closing, except for those covenants and agreements that are expressly limited by their terms to other dates or times, which will survive only to such dates or times.  No remedy conferred by any of the specific provisions of this Agreement is intended to be exclusive of any other remedy, and each remedy shall be cumulative and shall be in addition to every other remedy given hereunder or hereafter existing at law or in equity or by statute or otherwise, including but not limited to the right to the equitable remedy of specific performance.  However,

-54-

any breach by either Northwest or Pinnacle Corp. of the representations and warranties made by either of them in Article V will not be deemed a breach of this Agreement for the purposes of determining whether an Early Termination Event has occurred, other than if such breach is the result of fraud by Northwest.

ARTICLE XV
