Attention:  Mr. Curtis E. Sawyer
            Chief Financial Officer

                            REVOLVING CREDIT FACILITY

Gentlemen:

         We are pleased to make available to you a revolving credit facility, on
the terms and subject to the conditions set forth in this letter agreement. For
convenience only, we have included section captions in this letter agreement.
SCHEDULE I annexed hereto lists the defined terms used in this letter agreement
and the Sections in which those terms are defined.

         SECTION 1. THE LOANS. We agree, on the terms and subject to the
conditions hereinafter set forth, to make loans (the "LOANS") to you from time
to time during the period from the date hereof to the date (the "TERMINATION
DATE") which is the earliest of:

                  (a) _______, 2003, PROVIDED that, in the event you are unable
         to arrange the Replacement Credit Facility on or prior to such date,
         such date may be extended by you on at least ten Business Days' prior
         written notice from you to us furnished no earlier than ________, 2003
         to a date set forth in such notice and in no event later than ________,
         2004;

                  (b) the date notice is given by us to you pursuant to SECTION
         14;

                  (c) the date on which you obtain the Replacement Credit
         Facility; and

                  (d) the date on which the Airline Services Agreement is
         terminated.

The aggregate amount of all Loans outstanding from time to time may not exceed
$50,000,000, as such amount may be reduced pursuant to SECTION 4 (such amount,
as so reduced, being the "COMMITMENT AMOUNT"). Each Loan must be in an amount
which is an integral multiple of $100,000. Subject to the terms hereof, you may
from time to time borrow, prepay and reborrow amounts pursuant hereto.
<PAGE>

         SECTION 2. MAKING THE LOANS. We will make Loans on at least two
Business Days' prior written notice from you to us (a "BORROWING NOTICE")
specifying the proposed amount and date (which must be a Business Day) of such
Loan. Not later than 11:00 A.M. (Minneapolis time) on the date of such Loan and
upon fulfillment of the conditions set forth in SECTIONS 9 and 10, the proceeds
of such Loan will be made available to you in immediately available funds at
such bank in the United States as you may designate from time to time in writing
to us. The term "BUSINESS DAY" means a day of the year on which banks are not
required or authorized to close in Minneapolis, Minnesota.

         SECTION 3. INTEREST, ETC. Interest will accrue on the unpaid principal
amount of each Loan from the date such Loan is made until such principal amount
is paid in full (after, as well as before, judgment) at the Reference Rate.
Interest on each Loan will be payable on the last Business Day of each calendar
month and on the Termination Date.

         The "REFERENCE RATE" means a per annum rate of interest equal to the
sum of:

                  (i) from and after ______, 2002, 1% per annum,

         PLUS

                  (ii) the higher of

                  (A) the rate of interest most recently announced by The Chase
         Manhattan Bank ("CHASE") at its principal office in New York City as
         its prime rate, and

                  (B) the rate of interest most recently offered to Chase in the
         interbank market as the overnight federal funds rate plus .5%.

The Reference Rate is not necessarily intended to be the lowest rate of interest
determined by Chase in connection with extensions of credit. Changes in the rate
of interest on Loans will take effect simultaneously with each change in the
Reference Rate. On any overdue principal amount of any Loan, you will pay
interest (after, as well as before, judgment) payable on demand, at a
fluctuating interest rate per annum (the "DEFAULT RATE") equal to 4% per annum
over the Reference Rate in effect from time to time (but not less than the
Reference Rate in effect at the time of the applicable default).

         SECTION 4. REDUCTION OF THE COMMITMENT AMOUNT. You may, upon at least
five Business Days' notice to us, terminate or permanently reduce the unused
portion of the Commitment Amount, PROVIDED that each partial reduction must be
in a minimum amount of $1,000,000 and an integral multiple of $100,000.

         SECTION 5. REPAYMENT. On the Termination Date, the then aggregate
outstanding principal amount of all Loans will be due and payable in full.


                                       2
<PAGE>

         SECTION 6. PREPAYMENTS. You may, upon at least two Business Days'
notice to us, prepay the outstanding principal of the Loans, in whole or in
part, on any Business Day, in each case with accrued interest to the date of
such prepayment on the principal amount prepaid; PROVIDED, HOWEVER, that each
partial prepayment shall be in a principal amount in an integral multiple of $
100,000.

         SECTION 7. PAYMENTS, SET-OFF, COMPUTATIONS, ETC. Any term or provision
of this letter agreement to the contrary notwithstanding, you and we hereby
agree as follows:

                  (a) Your payments due hereunder or under any instrument
         delivered hereunder must be made by you (in immediately available
         funds) not later than 12:00 noon (Minneapolis time) on the day when due
         in lawful money of the United States to us at such account as we may
         from time to time designate in writing to you. Each such payment must
         be made by you free and clear of (and without deduction for) any and
         all present and future taxes, levies, imposts, deductions, charges,
         withholdings and all liabilities with respect thereto, excluding income
         and franchise taxes of the United States and any political subdivision
         thereof.

                  (b) All computations of interest described in SECTION 3 will
         be made by us on the basis of a year of 365 or 366 days, as the case
         may be, for the actual number of days (including the first day but
         excluding the last day) occurring in the period for which such interest
         is payable. Each computation by us of interest hereunder will be
         conclusive and binding for all purposes, absent manifest error.

                  (c) Whenever any payment to be made hereunder or under the
         Note or any other instrument delivered hereunder shall be stated to be
         due on a day other than a Business Day, such payment shall be made on
         the next succeeding Business Day, and such extension of time will, in
         such case, be included in the computation of payment of interest.

         SECTION 8. EVIDENCE OF DEBT. Your indebtedness to us resulting from
each Loan made from time to time hereunder will be evidenced by your promissory
note (the "NOTE"), in substantially the form attached hereto as EXHIBIT A,
delivered to us pursuant to CLAUSE (A) of SECTION 9. You hereby irrevocably
authorize us to make (or cause to be made) appropriate notations on the grid
attached to the Note (or on a continuation of such grid attached to the Note and
made a part thereof), which notations, if made, will evidence, INTER ALIA, the
date of, the outstanding principal of, and the interest rate applicable to, all
Loans evidenced thereby. Failure to record any notation on such grid (or on any
such continuation), or any error with respect thereto, will not, however, limit
or otherwise affect your obligations hereunder or under the Note to make
payments of principal of or interest on the Loans when due. We will also
maintain an account or accounts evidencing your indebtedness to us resulting
from each Loan made from time to time and the amounts of principal and interest
payable and paid from time to time hereunder. In any legal action or proceeding
in respect of this letter agreement, the entries made in such account or
accounts will be conclusive evidence of the existence and amounts of your
obligations to us therein recorded, absent manifest error.

         WHEREAS, pursuant to a letter agreement, dated as of __________, 2002
(together with all amendments and other modifications, if any, from time to time
thereafter made thereto, the "LETTER AGREEMENT"), between Pinnacle Airlines,
Inc., a Georgia corporation (the "BORROWER"), and the Lender, the Lender has
extended a commitment to make loans to the Borrower; and

performance of this Guaranty; and

         WHEREAS, it is in the best interests of the Guarantor to execute this

         NOW THEREFORE, for good and valuable consideration the receipt of which
is hereby acknowledged, and in order to induce the Lender to make the Loans

the Guarantor agrees, for the benefit of the Lender, as follows:

                               GUARANTY PROVISIONS

         SECTION 2.1. GUARANTY. The Guarantor hereby absolutely, unconditionally
and irrevocably (all of the following guaranteed and indemnified obligations
being collectively called the "GUARANTEED OBLIGATIONS")

                  (a) guarantees the full and punctual payment when due, whether
         at stated maturity, by required prepayment, declaration, acceleration,
         demand or otherwise, of all obligations of the Borrower now or
         hereafter existing under the Letter Agreement and the Note, whether for
         principal, interest, fees, expenses or otherwise, howsoever created,
         arising or evidenced, whether direct or indirect, absolute or
         contingent or now or hereafter existing or due or to become due
         (including in all cases all such amounts which would become due but for
         the operation of the automatic stay under Section 362(a) of the United
         States Bankruptcy Code, 11 U.S.C.ss.362(a), and the operation of
         Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11
         U.S.C.ss.502(b) andss.506(b)), and

                  (b) indemnifies and holds harmless the Lender and each holder
         of the Note for any and all costs and expenses (including reasonable
         attorney's fees and expenses) incurred by the Lender or such holder, as
         the case may be, in enforcing any rights under this Guaranty.

         SECTION 2.2. ACCELERATION OF GUARANTY. The Guarantor agrees that, in
the event of the dissolution or insolvency of the Borrower or the Guarantor, or
the inability or failure of the Borrower or the Guarantor to pay debts as they
become due, or an assignment by the Borrower or the Guarantor for the benefit of
creditors, or the commencement of any case or proceeding in respect of the
Borrower or the Guarantor under any bankruptcy, insolvency or similar laws, and
if such event shall occur at a time when any of the Guaranteed Obligations may
not then be due and payable, the Guarantor will pay to the Lender forthwith the
full amount which would be payable hereunder by the Guarantor if all such
Guaranteed Obligations were then due and payable.

         SECTION 2.3. GUARANTY ABSOLUTE, ETC. This Guaranty shall in all
respects be a continuing, absolute, unconditional and irrevocable guaranty of
payment, and shall remain in full force and effect until all Guaranteed
Obligations have been paid in full and the commitment of

<PAGE>

the Lender under the Letter Agreement shall have terminated. The Guarantor
guarantees that the Guaranteed Obligations will be paid strictly in accordance
with the terms of the Letter Agreement, the Note and each other document under
which they arise, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Lender or any holder of the Note with respect thereto. The liability of the
Guarantor under this Guaranty shall be absolute, unconditional and irrevocable
irrespective of:

                  (a) any lack of validity, legality or enforceability of the
         Letter Agreement or the Note;

                  (b) the failure of the Lender or any holder of the Note

                           (i) to assert any claim or demand or to enforce any
                  right or remedy against the Borrower or any other Person
                  (including any other guarantor) under the provisions of the
                  Letter Agreement, the Note or otherwise, or

                           (ii) to exercise any right or remedy against any
                  other guarantor of, or collateral securing, any Guaranteed
                  Obligations;

                  (c) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Guaranteed Obligations, or any
         other extension, compromise or renewal of any Guaranteed Obligation;

                  (d) any reduction, limitation, impairment or termination of
         any Guaranteed Obligations for any reason, including any claim of
         waiver, release, surrender, alteration or compromise, and shall not be
         subject to (and the Guarantor hereby waives any right to or claim of)
         any defense or set off, counterclaim, recoupment or termination
         whatsoever by reason of the invalidity, illegality, nongenuineness,
         irregularity, compromise, unenforceability of, or any other event or
         occurrence affecting, any Guaranteed Obligations;

                  (e) any amendment to, rescission, waiver, or other
         modification of, or any consent to departure from, any of the terms of
         the Letter Agreement or the Note;

                  (f) any addition, exchange, release, surrender or
         nonperfection of any collateral, or any amendment to or waiver or
         release or addition of, or consent to departure from, any other
         guaranty, held by the Lender or any holder of the Note securing any of
         the Guaranteed Obligations; or

                  (g) any other circumstance which might otherwise constitute a
         defense available to, or a legal or equitable discharge of, the
         Borrower, any surety or any guarantor.

         SECTION 2.4. REINSTATEMENT, ETC. The Guarantor agrees that this
Guaranty shall continue to be effective or be reinstated, as the case may be, if
at any time any payment (in whole or in part) of any of the Guaranteed
Obligations is rescinded or must otherwise be restored


                                      B-3
<PAGE>

by the Lender or any holder or the Note upon the insolvency, bankruptcy or
reorganization of the Borrower or otherwise, as though such payment had not been
made.

         SECTION 2.5 WAIVER, ETC. The Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Guaranty and any requirement that the Lender or
any holder of the Note protect, secure, perfect or insure any security interest
or lien, or any property subject thereto, or exhaust any right or take any
action against the Borrower or any other Person (including any other guarantor)
or entity or any collateral securing any Guaranteed Obligations.

         SECTION 2.6. WAIVER OF SUBROGATION. The Guarantor hereby irrevocably
waives any claim or other rights which it may now or hereafter acquire against
the Borrower that arise from the existence, payment, performance or enforcement
of the Guarantor's obligations under this Guaranty or any other document,
including any right of subrogation, reimbursement, exoneration, or
indemnification, any right to participate in any claim or remedy of the Lender
against the Borrower or any collateral which the Lender now has or hereafter
acquires, whether or not such claim, remedy or right arises in equity, or under
contract, statute or common law, including the right to take or receive from the
Borrower, directly or indirectly, in cash or other property or by set-off or in
any manner, payment or security on account of such claim or other rights. If any
amount shall be paid to the Guarantor in violation of the preceding sentence and
the Guaranteed Obligations shall not have been paid in cash in full and the
commitment of the Lender under the Letter Agreement and any other commitments by
the Lender to the Borrower have not been terminated, such amount shall be deemed
to have been paid to the Guarantor for the benefit of, and held in trust for,
the Lender, and shall forthwith be paid to the Lender to be credited and applied
upon the Guaranteed Obligations, whether matured or unmatured. The Guarantor
acknowledges that it will receive direct and indirect benefits from the
financing arrangements contemplated by the Letter Agreement and that the waiver
set forth in this Section is knowingly made in contemplation of such benefits.

         SECTION 2.7. SUCCESSORS, TRANSFEREES AND ASSIGNS; TRANSFERS OF NOTE,
ETC. This Guaranty shall:

                  (a) be binding upon the Guarantor, and its successors,
         transferees and assigns; and

                  (b) inure to the benefit of and be enforceable by the Lender,
         each holder of the Note and each of their respective successors,
         transferees and assigns.

Without limiting the generality of the foregoing CLAUSE (B), the Lender may
assign or otherwise transfer (in whole or in part) the Note or any Loan held by
it to any other Person or entity, and such other Person or entity shall
thereupon become vested with all rights and benefits in respect thereof granted
to the Lender under the Letter Agreement, the Note, this Guaranty or otherwise,
subject, however, to any contrary provisions in such assignment or transfer.

                  (d) This Guaranty is the legal, valid and binding obligation

         its terms.

                  (e) The Guarantor is not an "investment company", or a company

                                    COVENANT

         The Guarantor covenants and agrees that, so long as any portion of the
Guaranteed Obligations shall remain unpaid or the Lender shall have any
outstanding commitment to the Borrower under the Letter Agreement, the Guarantor

and free and clear of all liens and security interests, all of the outstanding
shares of capital stock of the Borrower.

Gentlemen:

         This letter is furnished to you pursuant to CLAUSE (H) of SECTION 9 of
the letter agreement, dated ________, 2002 (the "Letter Agreement"), between
Pinnacle Airlines, Inc., a Georgia corporation (the "Borrower") and you. Terms
defined in the Letter Agreement are used herein as therein defined.

         We have acted as counsel for the Borrower and the Guarantor in
connection with the preparation, negotiation, execution and delivery of, and the
initial borrowing made under, the Letter Agreement. The Borrower and the
Guarantor are collectively referred to herein as the "LOAN PARTIES".

         In that connection, we have examined:

         (1) the Letter Agreement, the Note and the Guaranty (collectively, the
"LOAN DOCUMENTS");

         (2) the [Articles] [Certificate] of Incorporation of each Loan Party
and all amendments thereto (its "CHARTER");

         (3) the by-laws of each Loan Party and all amendments thereto (its
"By-laws");

         (4) the other documents furnished by the Borrower pursuant to SECTION 9
of the Letter Agreement;

         (5) a certificate of the Secretary of State of Georgia, dated
_____________, 2002, attesting to the due incorporation, continued corporate
existence and good standing of the Borrower in that state; and

         (6) a certificate of the Secretary of State of Delaware, dated
_____________, 2002, attesting to the due incorporation, continued corporate
existence and good standing of the Guarantor in that state.

         We have also examined the originals, or copies certified to our
satisfaction, of the documents listed in a certificate of the chief financial
officer of the Borrower, dated the date
<PAGE>

hereof (the "Certificate"), certifying that the documents listed in such
certificate are all of the indentures, loan or credit agreements, leases,
guarantees, mortgages, security agreements, bonds, promissory notes, and other
agreements or instruments, and all of the orders, writs, judgments, awards,
injunctions and decrees, which affect or purport to affect the Borrower's right
to borrow money or any Loan Party's obligations under the Loan Documents to
which it is a party. In addition, we have examined the originals, or copies
certified to our satisfaction, of such other corporate records of each Loan
Party, certificates of public officials and of officers of each Loan Party, and
agreements, instruments and other documents, as we have deemed necessary as a
basis for the opinions expressed below. As to questions of fact material to such
opinions, we have, when relevant facts were not independently established by us,
relied, to the extent we deemed appropriate, upon certificates of Loan Parties
or their officers, including the Certificate, or of public officials. We have
assumed the due execution and delivery, pursuant to due authorization, of the
Letter Agreement by you.

         We are qualified to practice law in the State of Minnesota and we do
not purport to be experts on any laws other than the laws of the State of
Minnesota, the General Corporation Law of the State of Delaware, and the Federal
laws of the United States of America and, for purposes of paragraphs 1 and 2
below, the laws of the State of Georgia.

         Based upon the foregoing and upon such investigation as we have deemed
necessary, we are of the following opinion:

         1. Each Loan Party is a corporation duly organized, validly existing
and in good standing under the laws of the State of its incorporation.

         2. The execution, delivery and performance by each Loan Party of the
are within its corporate powers, have been duly authorized by all necessary
corporate action, and do not contravene

         (a) its Charter or By-laws;

         (b) any law, rule or regulation applicable to it (including, without
limitation, Regulation G, T, U or X of the Board of Governors of the Federal
Reserve System); or

         (c) any legal restriction or contractual restriction binding on or
affecting it contained in any document listed in the Certificate.

         3. The Loan Documents have been duly executed and delivered on behalf
of each Loan Party which is a party thereto.

         4. No authorization, approval or other action by, and no notice to or
filing with, any governmental authority or regulatory body or other Person is
required for the due execution, delivery and performance by each Loan Party of
each Loan Document to which it is a party.

         5. Each Loan Document is the legal, valid and binding obligation of
each Loan Party which is a party thereto enforceable against such Loan Party in
accordance with their respective terms.

         6. To the best of our knowledge, there is no pending or threatened
action or proceeding against either Loan Party before any court, governmental
agency or arbitrator which purport to affect the legality, validity, binding
effect or enforceability of any Loan Document.

         7. Neither Loan Party is an "investment company" or a company
"controlled" by an "investment company", within the meaning of the Investment
Company Act of 1940, as amended.

         8. Neither Loan Party is a "holding company", a "subsidiary company" of
a "holding company" or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company", within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

         The opinions set forth above are subject to the following
qualifications:

         (a) Our opinion in paragraph 3 above is subject to the effect of any
applicable bankruptcy, insolvency, reorganization, moratorium or similar law
affecting creditors' rights generally.

         (b) Our opinion in paragraph 3 above is subject to the effect of
general principles of equity (regardless of whether considered in a proceeding
in equity or at law).

                                                     Very truly yours,
