                          OF
               VANGUARD AIRLINES, INC.

             VOID AFTER SEPTEMBER 8, 2007

     This Warrant is issued to The Hambrecht 1980 Revocable
Trust, or its registered assigns (the "Holder") by Vanguard
Airlines, Inc., a Delaware corporation (the "Company"), on
September 8, 2000 (the "Warrant Issue Date").  This Warrant is
issued pursuant to the terms of that certain Unit Purchase
Agreement dated as of September 8, 2000 (the "Purchase
Agreement").

     1.   PURCHASE SHARES.  Subject to the terms and conditions
hereinafter set forth and set forth in the Purchase Agreement,
the Holder is entitled, upon surrender of this Warrant at the
principal office of the Company (or at such other place as the
Company shall notify the holder hereof in writing), to purchase
from the Company up to one million one hundred eighty six
thousand and eight hundred and ninety eight (1,186,898), fully
paid and nonassessable shares of Common Stock of the Company, as
constituted on the Warrant Issue Date (the "Common Stock").  The
number of shares of Common Stock issuable pursuant to this
Section 1 (the "Shares") shall be subject to adjustment pursuant
to Section 8 hereof.

     2.   EXERCISE PRICE.  The purchase price for the Shares
shall be $1.89 per share as adjusted from time to time pursuant
to Section 8 hereof (the "Exercise Price").

     3.   EXERCISE PERIOD.  This Warrant shall be exercisable, in
whole or in part, during the term commencing on September 8, 2000
and ending at 5:00 p.m. on the seventh anniversary date of the
Warrant Issue Date (the "Exercise Period").

     4.   METHOD OF EXERCISE.  While this Warrant remains
outstanding and exercisable in accordance with Section 3 above,
the Holder may exercise, in whole or in part, the purchase rights
evidenced hereby.  Such exercise shall be effected by:

          (a)  the surrender of the Warrant, together with a duly
executed copy of the form of Notice of Election Exercise attached
hereto, to the Secretary of the Company at its principal offices;
and
<PAGE>
          (b)  the payment to the Company of an amount equal to
the aggregate Exercise Price for the number of Shares being
purchased.

     5.   NET EXERCISE.  In lieu of exercising this Warrant
pursuant to Section 4, the Holder may elect to receive, without
the payment by the Holder of any additional consideration, shares
of Common Stock equal to the value of this Warrant (or the
portion thereof being canceled) by surrender of this Warrant at
the principal office of the Company together with notice of such
election, in which event the Company shall issue to the holder
hereof a number of shares of Common Stock computed using the
following formula:

                      X = Y (A-B)
                          -------
                            A

     Where:    X =  The number of shares of Common
                    Stock to be issued to the Holder pursuant to
                    this net exercise;
               Y =  The number of Shares in respect of which the
                    net issue election is made;
               A =  The fair market value of one share of the
                    Common Stock at the time the net issue
                    election is made;
               B =  The Exercise Price (as adjusted to the date
                    of the net issuance).

For purposes of this Section 5, the fair market value of one
share of Common Stock as of a particular date shall be determined
as follows: (i) if traded on a securities exchange or through the
Nasdaq National Market, the value shall be deemed to be the
average of the closing prices of the securities on such exchange
over the twenty (20) day period ending three (3) days prior to
the net exercise election; (ii) if actively traded over-the-
counter, the value shall be deemed to be the average of the
closing bid or sale prices (whichever is applicable) over the
twenty (20) day period ending three (3) days prior to the net
exercise; and (iii) if there is no active public market, the
value shall be the fair market value thereof, as determined in
good faith by the Board of Directors of the Company.

     6.   CERTIFICATES FOR SHARES.  Upon the exercise of the
purchase rights evidenced by this Warrant, one or more
certificates for the number of Shares so purchased shall be
issued as soon as practicable thereafter (with appropriate
restrictive legends, if applicable), and in any event within five
(5) days of the delivery of the subscription notice.

     7.   ISSUANCE OF SHARES.  The Company covenants that the
Shares, when issued pursuant to the exercise of this Warrant,
will be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens, and charges with respect to the
issuance thereof.

     8.   ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES.  The
number of and kind of securities purchasable upon exercise of
this Warrant and the Exercise Price shall be subject to
adjustment from time to time as follows:
<PAGE>
          (a)  SUBDIVISIONS; COMBINATIONS AND OTHER ISSUANCES.
If the Company shall at any time prior to the expiration of this
Warrant subdivide its Common Stock, by split-up or otherwise, or
combine its Common Stock, or issue additional shares of its
Common Stock (or securities convertible into, or otherwise
entitling the holders thereof to receive, Common Stock) as a
dividend with respect to any shares of its Common Stock, the
number of Shares issuable on the exercise of this Warrant shall
forthwith be increased in the case of a subdivision or stock
dividend, or proportionately decreased in the case of a
combination.  Appropriate adjustments shall also be made to the
Exercise Price payable per share, but the aggregate Exercise
Price payable for the total number of Shares purchasable under
this Warrant (as adjusted) shall remain the same.  Any adjustment
under this Section 8(a) shall become effective at the close of
business on the date the subdivision or combination becomes
effective, or as of the record date of such dividend, or in the
event that no record date is fixed, upon the making of such
dividend.

          (b)  RECLASSIFICATION, REORGANIZATION AND
CONSOLIDATION.  In case of any reclassification, capital
reorganization, or change in the Common Stock of the Company
(other than as a result of a subdivision, combination, or stock
dividend provided for in Section 8(a) above), then, as a
condition of such reclassification, reorganization, or change,
lawful provision shall be made, and duly executed documents
evidencing the same from the Company or its successor shall be
delivered to the Holder, so that the Holder shall have the right
at any time prior to the expiration of this Warrant to purchase,
at a total price equal to that payable upon the exercise of this
Warrant, the kind and amount of shares of stock and other
securities and property receivable in connection with such
reclassification, reorganization, or change by a holder of the
same number of shares of Common Stock as were purchasable by the
Holder immediately prior to such reclassification,
reorganization, or change.  In any such case appropriate
provisions shall be made with respect to the rights and interests
of the Holder so that the provisions hereof shall thereafter be
applicable with respect to any shares of stock or other
securities and property deliverable upon exercise hereof, and
appropriate adjustments shall be made to the Exercise Price per
share payable hereunder, provided the aggregate Exercise Price
shall remain the same.

          (c)  DILUTIVE ISSUANCES.  The Exercise Price shall be
subject to adjustment from time to time as follows:

               (i)  (A)  If the Company shall issue, after the
Warrant Issue Date, any Additional Stock (as defined below)
without consideration or for a consideration per share less than
the Unit Purchase Price (as defined in the Unit Purchase
Agreement) in effect immediately prior to the issuance of such
Additional Stock, the Exercise Price in effect immediately prior
to each such issuance shall forthwith (except as otherwise
provided in this clause (i)) be adjusted to a price equal to the
price paid per share for such Additional Stock [plus ten percent
(10%)]; provided, however that the Exercise Price shall not be
adjusted to a price below $0.10 (as adjusted for stock splits,
stock dividends, combinations, recapitalizations or like changes
in the Company's capital structure).
<PAGE>
                    (B)  In the case of the issuance of Common
Stock for cash, the consideration shall be deemed to be the
amount of cash paid therefor before deducting any reasonable
discounts, commissions or other expenses allowed, paid or
incurred by the Company for any underwriting or otherwise in
connection with the issuance and sale thereof.

                    (C)  In the case of the issuance of Common
Stock for a consideration in whole or in part other than cash,
the consideration other than cash shall be deemed to be the fair
value thereof as determined by the Board of Directors
irrespective of any accounting treatment.

                    (D)  In the case of the issuance of options
to purchase or rights to subscribe for Common Stock, securities
by their terms convertible into or exchangeable for Common Stock
or options to purchase or rights to subscribe for such
convertible or exchangeable securities, the following provisions
shall apply for all purposes of this subsection 8(c)(i) and
subsection 8(c)(ii):

                        (1)  The number of shares of Common
Stock deliverable upon exercise (to the extent then exercisable)
of such options to purchase or rights to subscribe for Common
Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to
the consideration (determined in the manner provided in
subsections 8(c)(i)(B) and 8(c)(i)(C)), if any, received by the
Company upon the issuance of such options or rights plus the
minimum exercise price provided in such options or rights for the
Common Stock covered thereby.

                         (2)  The number of shares of Common
Stock deliverable upon conversion of, or in exchange (to the
extent then convertible or exchangeable) for, any such
convertible or exchangeable securities or upon the exercise of
options to purchase or rights to subscribe for such convertible
or exchangeable securities and subsequent conversion or exchange
thereof shall be deemed to have been issued at the time such
securities were issued or such options or rights were issued and
for a consideration equal to the consideration, if any, received
by the Company for any such securities and related options or
rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Company upon the
conversion or exchange of such securities or the exercise of any
related options or rights (the consideration in each case to be
determined in the manner provided in subsections 8(c)(i)(B) and
(c)(i)(C)).

                         (3)  In the event of any change in the
consideration payable to the Company upon exercise of such
options or rights or upon conversion of or in exchange for such
convertible or exchangeable securities, including, but not
limited to, a change resulting from the antidilution provisions
thereof, the Exercise Price, to the extent in any way affected by
such options, rights or securities, shall be recomputed to
reflect such change, but no further adjustment shall be made for
the actual issuance of Common Stock or any payment of such
consideration upon the exercise of any such options or rights or
the conversion or exchange of such securities.

                         (4)  Upon the expiration of any such
options or rights, the termination of any such rights to convert
<PAGE>
or exchange or the expiration of any options or rights related to
such convertible or exchangeable securities without the exercise,
conversion or exchange of any of the foregoing into Common Stock,
the Exercise Price  shall be recomputed to reflect the assumption
that none of such options, rights, or convertible or exchangeable
securities had ever been issued.

                         (5)  The Common Stock deemed issued and
the consideration deemed paid therefor pursuant to subsections
8(c)(i)(D)( 1) and (2) shall be appropriately adjusted to reflect
any change, termination or expiration of the type described in
either subsection 8(c)(i)(D)(3) or (4).

               (ii)  "Additional Stock" shall mean any shares of Common Stock
issued (or deemed to have been issued pursuant to subsection
8(c)(i)(D)) by the Company after the date hereof other than:

                    (A)  Common Stock issued pursuant to a transaction described
in subsection 8(a) or (b) hereof; or

                    (B)  Shares of Common Stock issuable or issued to employees,
consultants, directors or vendors (if in transactions with
primarily non-financing purposes) of the Company directly or
pursuant to a stock option plan, employee stock purchase plan or
other plan or agreement approved by the Board of Directors of the
Company.

          (D)  NOTICE OF ADJUSTMENT.  When any adjustment is
required to be made in the number or kind of shares purchasable
upon exercise of the Warrant, or in the Exercise Price, the
Company shall promptly notify the holder of such event and of the
number of shares of Common Stock or other securities or property
thereafter purchasable upon exercise of this Warrant.

     9.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or
scrip representing fractional shares shall be issued upon the
exercise of this Warrant, but in lieu of such fractional shares
the Company shall make a cash payment therefor on the basis of
the Exercise Price then in effect.

     10.  NO STOCKHOLDER RIGHTS.  Prior to exercise of this
Warrant, the Holder shall not be entitled to any rights of a
stockholder with respect to the Shares, including (without
limitation) the right to vote such Shares, receive dividends or
other distributions thereon, exercise preemptive rights or be
notified of stockholder meetings, and such holder shall not be
entitled to any notice or other communication concerning the
business or affairs of the Company.  However, nothing in this
Section 10 shall limit the right of the Holder to be provided the
Notices required under this Warrant or the Purchase Agreement.
