and, collectively, the "Warrants" and the certificates evidencing the Warrants
                        --------
being hereinafter referred to as the "Warrant Certificates") entitling the
                                      --------------------
Holder thereof to initially purchase 18.02885 shares of the Company's common

         NOW, THEREFORE, in consideration of the purchase of the Units by the
Initial Purchaser and for other good and valuable consideration, the adequacy
and receipt of which is hereby acknowledged, and for the purpose of defining the
respective rights and obligations of the Company, the Warrant Agent and the
Holders, the parties hereto agree as follows:

                                   ARTICLE I

                    ISSUANCE, FORM, EXECUTION, DELIVERY AND
                     REGISTRATION OF WARRANT CERTIFICATES

         SECTION 1.1.Issuance of Warrants. Each Warrant Certificate shall, when
                     --------------------
countersigned by the Warrant Agent, evidence the number of Warrants specified
therein, and each Warrant evidenced thereby shall represent the right, subject
to the provisions contained herein and therein, to purchase from the Company

property purchasable and deliverable upon exercise of a Warrant as provided in
Article V) at the price specified herein and therein, in each case subject to
---------
adjustment as provided herein and therein.
<PAGE>

         SECTION 1.2. Form of Warrant Certificates. The Warrants will be issued
                      ----------------------------
only in certificated form. The Warrant Certificates evidencing the Warrants to
be delivered pursuant to this Warrant Agreement shall be substantially in the
form set forth in Exhibit A attached hereto, dated the date on which
                  ---------
countersigned.

         SECTION 1.3. Execution of Warrant Certificates. The Warrant
                      ---------------------------------
Certificates shall be executed on behalf of the Company by its President or any
Vice President and attested to by its Secretary or Assistant Secretary, under
its corporate seal. Such signatures may be the manual or facsimile signatures of
the present or any future such officers. The seal of the Company may be in the
form of a facsimile hereof and may be impressed, affixed, imprinted or otherwise
reproduced on the Warrant Certificates. Typographical and other minor errors or
defects in any such reproduction of the seal or any such signature shall not
affect the validity or enforceability of any Warrant Certificate that has been
duly countersigned and delivered by the Warrant Agent.

         In case any officer of the Company who shall have signed any of the
Warrant Certificates shall cease to be such officer before the Warrant
Certificate so signed shall be countersigned and delivered by the Warrant Agent
or disposed of by the Company, such Warrant Certificate nevertheless may be
countersigned and delivered or disposed of as though the person who signed such
Warrant Certificate had not ceased to be such officer of the Company; and any
Warrant Certificate may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Warrant Certificate, shall be the
proper officers of the Company, although at the date of the execution and
delivery of this Warrant Agreement any such person was not such an officer.

         SECTION 1.4. Appointment of Warrant Agent. The Company hereby appoints
                      ----------------------------
the Warrant Agent to act as agent for the Company in accordance with the terms
and conditions set forth in this Agreement, and the Warrant Agent hereby accepts
such appointment.

         SECTION 1.5. Authentications and Delivery. Subject to the immediately
                      ----------------------------
following paragraph of this Section 1.5, Warrant Certificates shall be
                            -----------
authenticated by manual signature and dated the date of authentication by the
Warrant Agent and shall not be valid for any purpose unless so authenticated and
dated. The Warrant Certificates shall be numbered and shall be registered in the
Warrant Register (as defined in Section 1.7 hereof).
                                -----------

         Upon the receipt by the Warrant Agent of a written order of the
Company, which order shall be signed by its President or any Vice President and
attested to by its Secretary or Assistant Secretary and shall specify the amount
of Warrants to be authenticated, the date of such Warrants and such other
information as the Warrant Agent may reasonably request, without any further
action by the Company, the Warrant Agent is authorized, upon receipt from the
Company at any time and from time to time of the Warrant Certificates, duly
executed as provided in Section 1.3 hereof, to authenticate the Warrant
                        -----------
Certificates and deliver them. Such authentication shall be by a duly authorized
signatory of the Warrant Agent (although it shall not be necessary for the same
signatory to sign all Warrant Certificates).

         In case any authorized signatory of the Warrant Agent who shall have
authenticated any of the Warrant Certificates shall cease to be such authorized
signatory before the Warrant Certificate shall be disposed of by the Company,
such Warrant Certificate nevertheless may be

                                       2
<PAGE>

delivered or disposed of as though he person who authenticated such Warrant
Certificate had not ceased to be such authorized signatory of the Warrant Agent;
and any Warrant Certificate may be authenticated on behalf of the Warrant Agent
by such persons as, at the actual time of authentication of such Warrant
Certificates, shall be the duly authorized signatories of the Warrant Agent,
although at the time of the execution and delivery of this Warrant Agreement any
such person is not an authorized signatory.

         The Warrant Agent's authentication on all Warrant Certificates shall be
in substantially the form set forth in Exhibit A hereto.
                                       ---------

         SECTION 1.6. Separation of Warrants and Notes. The Warrants will be
                      --------------------------------
separately transferable from the Notes immediately upon issuance of the Units
(the "Separation Date").
      ---------------

         SECTION 1.7. Registrar and Warrant Register. The Company will keep, at
                      ------------------------------
the office or agency maintained by the Company for such purpose, a register or
registers in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of, and registration of transfer
and exchange of, Warrants as provided in this Article. Each Person designated by
the Company from time to time as a Person authorized to register the transfer
and exchange of the Warrants is hereinafter called, individually and
collectively, the "Registrar". Initially, Wilmington Trust Company shall act as
Registrar. Upon written notice to the Warrant Agent and any acting Registrar,
the Company may appoint a successor Registrar for such purposes.

         The Company will at all times designate one Person (who may be the
Company and who need not be a Registrar) to act as repository of a master list
of names and addresses of the Holders (the "Warrant Register"). The Company will
                                            ----------------
act as such repository unless and until some other Person is, by written notice
from the Company to the Warrant Agent and the Registrar, designated by the
Company to act as such. The Company shall cause each Registrar to furnish to
such repository, on a current basis, such information as to all registrations of
transfer and exchanges effected by such Registrar, as may be necessary to enable
such repository to maintain the Warrant Register on as current a basis as is
practicable.

         SECTION 1.8. Registration of Transfers and Exchanges.
                      ---------------------------------------

         (a)   Transfer and Exchange. When Warrants are presented to the Warrant
Agent with a request:

                   (i)   to register the transfer of the Warrants; or

                  (ii)   to exchange such Warrants for an equal number of
         Warrants, the Warrant Agent shall register the transfer or make the
         exchange as requested if the requirements under this Warrant Agreement
         as set forth in this Section 1.8 for such transactions are met;
                              -----------
         provided, however, that the Warrants presented or surrendered for
         registration of transfer or exchange:

                            instruction of transfer in form satisfactory to the
                            Company and the Warrant Agent, duly executed by the
                            Holder thereof or by its attorney, duly authorized
                            in writing and

                       (y)  in the case of Warrants the offer and sale of which
                            has not been registered under the Securities Act,
                            and are presented for transfer or exchange prior to
                            (x) the date which is two years after the later of
                            the date of original issue (the "Issue Date") and
                                                             ----------
                            the last date on which the Company or any affiliate
                            of the Company was the owner of such Warrant, or any
                            predecessor thereto and (y) such later date, if any,
                            as may be required by any subsequent change in
                            applicable law (the "Resale Restriction Termination
                                                 ------------------ -----------
                            Date"), such Warrants shall be accompanied, in the
                            ----
                            sole discretion of the Company, by the following
                            additional information and documents, as applicable:

                            (A)   if such Warrant is being delivered to the
                                  Warrant Agent by a Holder for registration in
                                  the name of such Holder, without transfer, a
                                  certification from such Holder to that effect
                                  (in substantially the form of Exhibit B
                                                                ---------
                                  hereto); or

                            (B)   if such Warrant is being transferred in
                                  reliance on any exemption from the
                                  registration requirements of the Securities

and of any change of location thereof. The Company hereby designates the
corporate trust office of the Warrant Agent in Wilmington, Delaware (the
"Warrant Agent Office"), as the initial agency maintained for each such purpose.

         (d)   In the event that any Holder of Warrant Certificates delivers
such Warrant Certificates to the Company and indicates on the Election to
Exercise that such Holder intends to exercise all, or any portion of, the
Warrants represented by such Warrant Certificate to satisfy its obligation to
pay the Exercise Price in respect thereof by virtue of the provisions of this
Section 2.2(d), such Holder shall become entitled to receive, instead of the

         For purposes of Rule 144 under the Securities Act, the Company and the
Warrant Agent, on behalf of the Holders, hereby agree that the exercise of any
Warrants in accordance with this Section 2.2(d) shall be deemed to be a

writing; and (iv) as soon as practicable, advise the Company in writing of the
number of Warrants exercised in accordance with the terms and conditions of this
Warrant Agreement and the Warrant Certificates, the instructions of each
exercising Holder with respect to delivery of the Warrant Shares to which such
Holder is entitled upon such exercise, and such other information as the Company
shall reasonably request.

         (g)   Subject to Section 5.2 hereof, as soon as practicable after the
                          -----------
exercise of any Warrant or Warrants in accordance with the terms hereof, the
Company shall issue or cause to be issued to or upon the written order of the
registered Holder evidencing such exercised Warrant or Warrants, a certificate
or certificates evidencing the Warrant Shares to which such Holder is entitled,
in fully registered form, registered in such name or names as may be directed by
such Holder pursuant to the Election to Exercise, as set forth on the reverse of
the Warrant Certificate. The Warrant Agent shall have no obligation to ascertain
the number of Warrant Shares to be issued with respect to the exercised Warrant
or Warrants. Such certificate or certificates evidencing the Warrant Shares
shall be deemed to have been issued and any Persons who are designated to be
named therein shall be deemed to have become the Holder of record of such
Warrant Shares as of the close of business on the Exercise Date. After such
exercise of any Warrant or Warrants, the Company shall also issue or cause to be
issued to or upon the written order of the registered Holder of such Warrant
Certificate, a new Warrant Certificate, countersigned by the Warrant Agent
pursuant to the Company's written instruction, evidencing the number of
Warrants, if any, remaining unexercised (unless such Warrants shall have
expired).

so delivered, shall be canceled by it and

of any Person in respect of such issuance and free of any security interest,
lien or other encumbrance of any kind or nature created by, arising out of
actions of, the Company, any subsidiary or any affiliate of the Company.

                                  ADJUSTMENTS

         SECTION 5.1.    Adjustment of Exercise Price and Number of Warrant
                         --------------------------------------------------
Shares Issuable. The Exercise Price and the number and kind of Warrant Shares
---------------
purchasable upon the exercise of each Warrant shall be subject to adjustment
from time to time as follows:

         (a)   Stock Dividends, Subdivisions and Combinations. In case the
Company shall hereafter (A) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock, (B) reclassify by subdivision its
outstanding shares of Common Stock into a

                                       12
<PAGE>

greater number of shares or (C) reclassify by combination its outstanding shares
of Common Stock into a smaller number of shares, (i) the number of Warrant
Shares purchasable upon exercise of each Warrant immediately prior thereto shall
be adjusted so that the Holder of any Warrant Certificate thereafter exercised
shall be entitled to receive the number of Warrant Shares which such Holder
would have owned immediately following such action had such Warrant been
exercised immediately prior thereto, and (ii) the Exercise Price shall be
adjusted by multiplying such Exercise Price immediately prior to such adjustment
by a fraction, the numerator of which shall be the number of Warrant Shares
purchasable upon the exercise of each Warrant immediately prior to such
adjustment, and the denominator of which shall be the number of Warrant Shares
purchasable immediately thereafter. An adjustment made pursuant to this Section
                                                                        -------
5.1(a) shall become effective immediately after the record date, in the case of
------
a dividend, and shall become effective immediately after the effective date, in
the case of a subdivision, combination or reclassification. If, as a result of
an adjustment made pursuant to this Section 5.1(a), the Holder of any Warrant
                                    --------------
Certificate thereafter exercised shall become entitled to receive shares of two
or more classes of capital stock of the Company, the Board of Directors of the
Company shall determine, in its reasonable discretion, the allocation of the
adjusted Exercise Price between or among shares of such classes of capital
stock.

         (b)   Reclassification, Combinations, Mergers, etc. If (A) any capital
reorganization, reclassification or change of outstanding shares of Common Stock
(other than as set forth in Section 5.1(a) and other than a change in par value,
                            --------------
or from par value to no par value, or from no par value to par value provided
that the Company shall not increase the par value of the Common Stock to exceed
the Exercise Price), or (B) in case of any consolidation or merger of the
Company with or into another corporation or other entity (other than a merger in
which the Company is the continuing corporation and which does not result in any
reclassification or change of the then outstanding shares of Common Stock or
other capital stock of the Company (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)) or (C) in case of any sale or conveyance to another
corporation or other entity of all or substantially all of the assets of the
Company shall be effected in such a way that the holders of Common Stock shall
be entitled to receive shares of common stock, other securities or assets
(whether such stock, other securities or assets are issued or distributed by the
Company or another Person) with respect to or in exchange for Common Stock,
then, as a condition of such reclassification, reorganization, change,
consolidation, merger, sale or conveyance, the Company or such a successor or
purchasing corporation or other entity, as the case may be, shall forthwith make
lawful and adequate provision whereby the Holder of such Warrant Certificate
then outstanding shall have the right thereafter to receive on exercise of such
Warrant the kind and amount of shares of stock and other securities and assets
receivable upon such reclassification, reorganization, change, consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
that such holders would have been entitled to receive upon exercise of such
Warrant had such Warrant been exercised immediately before such
reclassification, reorganization, change, consolidation, merger, sale or
conveyance that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article V and enter into a supplemental warrant
                                 ---------
agreement so providing.

         For purposes of this Section 5.1(b), "shares of stock and other
                              --------------
securities and property" receivable upon a reclassification, change,
consolidation, merger, sale or conveyance

                                       13
<PAGE>

shall include stock of any successor or acquiring corporation of any class which
is not subject to redemption and shall also include any evidence of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event including any warrants or
other rights to subscribe for or purchase any such stock. If the issuer of
securities deliverable upon exercise of Warrants under the supplemental warrant
agreement is an affiliate of the formed, surviving or transferee corporation or
other entity, such issuer shall join in the supplemental warrant agreement.

         In case of any such reclassification, reorganization, merger,
consolidation or dispositions of assets, the successor or acquiring corporation
or other entity shall expressly assume the due and punctual observance and
performance of each and every covenant and condition of this Warrant Agreement
to be performed and observed by the Company and all the obligations and
liabilities hereunder, subject to such modifications as may be deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for adjustments of Warrant Shares into which
each Warrant is exercisable, which shall be as nearly equivalent as practicable
to the adjustments provided for in this Article V.
                                        ---------

         (c)   Issuances of Common Stock or Rights. In the event that the
Company shall, at any time or from time to time after the date hereof, issue,
sell distribute or otherwise grant (in any such case, a "Distribution") shares
                                                         ------------
of Common Stock or Rights, whether or not such Rights are immediately
exercisable, convertible or exchangeable, at a Consideration Per Share lower
than the per share Fair Market Value of the Common Stock on the date of such
issuance or sale, or if the Company shall amend any of the provisions of any
Rights, including, without limitation, a change in the purchase, conversion,
exchange or exercise price per share of Common Stock of any such Right, or the
Aggregate Consideration Receivable applicable to any such Right (other than
under or by reason of provisions designed to protect against dilution upon an
event which results in an adjustment pursuant to this Article V which is no less
                                                      ---------
favorable to the Holders than such adjustment is to the holder of such Rights),
then, immediately after the date of such issuance or sale,

                           (A)     the number of Warrant Shares purchasable upon
                  exercise of each Warrant shall be increased so that the
                  Holders thereafter will be entitled to receive the number of
                  Warrant Shares determined by multiplying:

                                   (i)   the number of shares of Common Stock
                  such Holders would have been entitled to receive immediately
                  before the date of such issuance or sale had such Holders
                  exercised their Warrants immediately prior thereto; by

                                   (ii)  a fraction, the numerator of which
                  shall be the sum of: (X) the number of shares of Common Stock
                  outstanding on such date plus (Y) the number of additional
                  shares of Common Stock offered for subscription or purchase
                  (or into which the Rights so offered are initially convertible
                  or exchangeable or exercisable, as the case may be), and the
                  denominator of which shall be the sum of: (X) the number of
                  shares of Common Stock outstanding on such date plus (Y) the
                  number of shares of Common Stock that the Aggregate
                  Consideration Receivable would

                                       14
<PAGE>

                  purchase at such per share Fair Market Value of the Common
                  Stock on the date of such issuance or sale, and

                           (B)     the Exercise Price in effect immediately
                  after such Distribution shall be adjusted by multiplying the
                  Exercise Price in effect immediately prior to such
                  Distribution by the quotient of:

                           (i)     the sum of: (A) the number of shares of
                  Common Stock outstanding immediately prior to such
                  Distribution; plus (B) the quotient of: (X) the Aggregate
                  Consideration Receivable; divided by (Y) the per share Fair
                  Market Value of the Common Stock; in each case immediately
                  prior to such Distribution; divided by

                           (ii)    the sum of: (A) the number of shares of
                  Common Stock outstanding immediately prior to such
                  Distribution; plus (B) the number of shares of Common Stock so
                  issued or sold (or initially issuable pursuant to any Rights).

                  No adjustment shall be made pursuant to subparagraph (A) above
which would decrease the number of shares of Common Stock purchasable upon
exercise of a Warrant. No adjustment shall be made pursuant to subparagraph (B)
above which would increase the Exercise Price of a Warrant.

                  For purposes of the foregoing calculation, the total maximum
number of shares of Common Stock issuable upon exercise, conversion or exchange,
as applicable, of all Rights shall be deemed to have been issued as of the date
of such Distribution and thereafter shall be deemed to be outstanding and the
Company shall be deemed to have received as consideration therefor the Aggregate
Consideration Receivable applicable thereto after giving effect to such
exercise, conversion or exchange. Except as provided in Section 5.1(g), no
                                                        --------------
additional adjustments of the Exercise Price shall be made upon the actual
exercise, exchange or conversion, as applicable, of such Rights.

                  (d)    Dividends and Distributions. In the event the Company
shall, at any time or from time to time after the date hereof, make or pay any
dividend of, or distribute to holders of Common Stock (in any such case, a
"Dividend"), shares of capital stock, any of its property or assets, including,
 --------
without limitation, cash, evidences of its indebtedness, Rights or other
securities (in each case, other than dividends payable in Common Stock)
(collectively, "Dividend Securities"), then, in each such case, the Company
                -------------------
shall reserve shares or other units of such Dividend Securities for distribution
to the Holders upon exercise of their Warrants so that, in addition to the
Warrant Shares issuable upon exercise thereof, such Holders will receive upon
such exercise the amount and kind of such Dividend Securities that such Holders
would have received if the Holders had, immediately prior to the record date for
the distribution of the Dividend Securities, exercised the Warrants.

                  (e)    Self-Tenders. If, at any time or from time to time
after the date hereof, the Company or any subsidiary of the Company shall
repurchase, by self-tender offer or otherwise, any shares of Common Stock of the
Company or any Right at a weighted average purchase price in

                                       15
<PAGE>

excess of the per share Fair Market Value of the Common Stock then on the
Business Day immediately prior to the earliest of (i) the date of such
repurchase, (ii) the commencement of an offer to repurchase or (iii) the public
announcement of either (such date being referred to as the "Determination
                                                            -------------
Date"), the Company shall (x) offer to repurchase the Warrant Shares on the same
----
terms and conditions on which it has offered to repurchase the shares of Common
Stock that were the subject of the self-tender or (y) offer to repurchase the
Warrants on the same terms and conditions on which it has offered to repurchase
the rights that were the subject of the self-tender.

                  (f)    Fair Market Value of Consideration Received.
Notwithstanding any provision to the contrary herein, for purposes of this
Article V, if any Rights shall be issued in connection with the issuance and
---------
sale of other securities of the Company, together comprising one integral
transaction in which no specific consideration is allocated to such Rights by
the parties thereto, such Rights shall be deemed to have been issued without
consideration, provided, however, that if any such Rights have an exercise price
(to the extent applicable) equal to or greater than the per share Fair Market
Value of the Common Stock on the date of issuance of such Rights, then such
Rights shall be deemed to have been issued for consideration equal to such
exercise price.

                  (g)    Deferral of Certain Adjustments. No adjustment need be
made for a change in the par value of the Common Stock; provided, however, the
Company shall not increase the par value of the Common Stock to exceed the
Exercise Price. All calculations under this Section 5.1 shall be made to the
                                            -----------
nearest 1/1,000 of one cent or to the nearest 1/1,000th of a Warrant Share, as
the case may be.

                  (h)    Other Adjustments. In the event that at any time, as a
result of an adjustment made pursuant to this Article V, Holders shall become
                                              ---------
entitled to receive any securities of the Company other than shares of Common
Stock, thereafter the number of such other securities so receivable upon
exercise of each Warrant and the Exercise Price applicable to such exercise
shall be subject to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the Warrant
Shares and the Exercise Price contained in this Article V, and all other
                                                ---------
relevant provisions of this Article V that are applicable to shares of Common
                            ---------
Stock shall be applicable to such other securities. In case at any time or from
time to time the Company shall take any action in respect of its outstanding
shares of Common Stock, other than any action described in this Article V, or
                                                                ---------
any event occurs as to which the provisions of this Article V are not strictly
                                                    ---------
applicable, then the number of Warrant Shares for which each Warrant is
exercisable shall be adjusted in such manner as may be equitable in the
circumstances and on terms as nearly equivalent as practicable to the provisions
with respect to the Warrant Shares and the Exercise Price contained in this
Article V and as shall be reasonably necessary, in the good faith opinion of the
---------
Board of Directors of the Company, to protect the exercise rights of the
Holders, but in no event shall any such adjustment have the effect of adversely
affecting the Holders. If the Company shall at any time or from time to time
issue, sell or distribute any shares of capital stock (other than Common Stock),
any evidences of indebtedness, any property or assets, Rights or other
securities, then, in each such case, such issuance, sale or distribution shall
be deemed to be of, or in respect of, Common Stock for purposes of this Article
                                                                        -------
V.
-

                  (i)    Statement of Warrant Certificates. Irrespective of any
adjustment in the number or kind of Warrant Shares issuable upon the exercise of
each Warrant or the Exercise Price, Warrant Certificates theretofore or
thereafter issued shall continue to express the same number and

                                       16
<PAGE>

kind of Warrant Shares and Exercise Price as are stated in the Warrant
Certificates initially issuable pursuant to this Warrant Agreement.

                  (j)    Increased Warrant Shares or Reduced Exercise Price.
From time to time, the Company may, for a period of not less than 20 Business
Days, in its discretion, upon written notice to the Warrant Agent, increase the
number of Warrant Shares purchasable upon the exercise of each Warrant, without
making any adjustment to the Exercise Price, or reduce the Exercise Price,
without making any adjustment to the number of Warrant Shares purchasable upon
the exercise of each Warrant; provided that in the event that the Company elects
to make any such adjustment, the Company shall make the same or proportional
adjustment, as the case may be, with respect to all outstanding Warrants.

                  (k)    No Adjustments for Certain Incentive Compensation.
Notwithstanding any other provision hereof, it is expressly understood that the
Warrants shall not be adjusted with respect to (a) Common Stock or Rights, in
any case, that may be issued to any of the Company's officers or employees
pursuant to the stock option plans or similar plans of the Company, including,
without limitation, under the AirTran Holdings, Inc. 1995 Employee Stock
Purchase Plan, 1993 Incentive Stock Options Plan, 1994 and 1996 stock option
plans, Airways Corporation's 1995 Stock Option Plan, and Airways Corporation's
1995 Director Stock Option Plan (collectively, the "Plans"), to the extent that
                                                    -----
shares of Common Stock or other securities issued or granted under such Plans
are issued or granted at a price, or with an exercise price, that is no less
than the per share Fair Market Value of the Common Stock at the date of grant or
issuance and such grant or issuance, together with all previous grants and
issuances under all such Plans, represents not more than 10% of the fully
diluted Common Stock at the time of such grant or issuance, (b) the issuance of
any Warrant Shares, or (c) the issuance of any Common Stock upon conversion of
the Convertible Notes.

                  (l)    No Impairment. The Company will not, by amendment of
its certificate of incorporation or through any reorganization, transfer of
assets, consolidation, merger, dissolution, liquidation, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the provisions of this Section 5.1 and in the taking of all such action as may
                       -----------
be necessary or appropriate in order to protect the rights of the Holders
against impairment.

                  (m)    Further Equitable Adjustments. If, after one or more
adjustments to the Exercise Price pursuant to this Section 5.1, the Exercise
                                                   -----------
Price cannot be reduced further without falling below the greater of (i) the par
value of the Common Stock or (ii) the lowest positive exercise price legally
permissible for warrants to acquire shares of common stock, the Company shall
make further adjustments to compensate the Holders, consistent with the
foregoing principles, as the Board of Directors of the Company, acting in good
faith, deems necessary, including an increase in the number of Warrant Shares
issuable upon exercise of outstanding Warrants and/or a cash payment to the
Holders.

                  (n)    Other Adjustments.

                                       17
<PAGE>

                         (i)    Adjustments shall be made pursuant to this
                  Section 5.1 successively whenever any of the events referred
                  -----------
                  to in Section 5.1(a) through Section 5.1(e), inclusive, shall
                        --------------         --------------
                  occur.

                         (ii)   If any Warrant shall be exercised subsequent to
                  the record date for any of the events referred to in this
                  Section 5.1, but prior to the effective date thereof,
                  -----------
                  appropriate adjustments shall be made immediately after such
                  effective date so that the Holder of such Warrant on such
                  record date shall have received, in the aggregate, the kind
                  and number of shares of Common Stock or other securities or
                  property or assets that it would have owned or been entitled
                  to receive on such effective date had such Warrant been
                  exercised prior to such record date.

                         (iii)  Shares of Common Stock owned by or held for the
                  account of the Company shall not, for purposes of the
                  adjustments set forth in this Section 5.1 be deemed
                                                -----------
                  outstanding.

                  (o)   Expiration of Rights. Upon the expiration of any Rights
referred to in this Section 5.1, without the exercise, exchange or conversion,
                    -----------
as applicable, thereof, the Exercise Price and the number of Warrant Shares
shall, upon such expiration, be readjusted and shall thereafter be such Exercise
Price and such number of Warrant Shares as would have been had such Exercise
Price and such number of Warrant Shares originally been adjusted (or had the
original adjustment not been required, as the case may be) as if:

                         (i)    the only shares of Common Stock so issued were
                  the shares of Common Stock, if any, actually issued or sold
                  upon the exercise of such Rights; and

                         (ii)   such shares of Common Stock, if any, were issued
                  or sold for the consideration actually received by the Company
                  upon such exercise plus the aggregate consideration, if any,
                  actually received by the Company for the issuance, sale or
                  grant of all such Rights, whether or not exercised; provided,
                  however, that no such readjustment shall have the effect of
                  increasing the Exercise Price by an amount in excess of the
                  amount of the reduction initially made in respect of the
                  issuance, sale, or grant of such Rights.

                  SECTION 5.2.  Fractional Interest. The Company shall not be
                                -------------------
required to issue fractional shares of Common Stock on the exercise of Warrants.
If more than one Warrant shall be presented for exercise in full at the same
time by the same Holder, the number of full shares of Common Stock which shall
be issuable upon such exercise shall be computed on the basis of the aggregate
number of shares of Common Stock which may be acquired on exercise of the
Warrants so presented. If any fraction of a share of Common Stock would, except
for the provisions of this Section 5.2, be issuable on the exercise of any
                           -----------
Warrant, the Company shall either (i) pay an amount in cash calculated by the
Company to equal the per share Fair Market Value of the Common Stock multiplied
by such fraction of a share of Common Stock computed to the nearest whole cent
or (ii) aggregate all such fractional shares of Common Stock into a whole number
of shares and sell such aggregated fractional shares on behalf of the Holders
entitled thereto in a public or private sale and distribute, on a pro rata
basis, the net cash proceeds therefrom to such Holders. While the Company will
use its best efforts to secure the best available sale price for such aggregated

                                       18
<PAGE>

fractional shares, such price shall not necessarily be the highest price
obtainable for such shares. By their acceptances of the Warrant Certificates,
Holders expressly waive any and all rights to receive any fraction of a share of
Common Stock or a stock certificate or scrip representing a fraction of a share
of Common Stock.

                  SECTION 5.3.  When Adjustment Not Required. If the Company
                                ----------------------------
shall take a record of the holders of its Common Stock for the purpose of
entitling them to receive a dividend or distribution or subscription or purchase
rights and shall, thereafter and before the distribution to stockholders
thereof, legally abandon its plan to pay or deliver such dividend, distribution,
subscription or purchase rights, then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made
in respect thereof shall be rescinded and annulled.

                  SECTION 5.4.  Treasury Stock. The sale or other disposition of
                                --------------
any issued shares of Common Stock owned or held by or for the account of the
Company shall be deemed an issuance thereof and, except for a voluntary tender
or exchange offer made by the Company or any subsidiary of the Company subject
to Section 13(e) of the Exchange Act, a repurchase thereof and designation of
such shares as treasury stock shall not be deemed to be a redemption thereof for
the purposes of this Warrant Agreement.

                  SECTION 5.5.  Notices to Warrant Agent and Holders. Whenever
                                ------------------------------------
the number of Warrant Shares is adjusted or the Exercise Price in respect
thereof is adjusted, as herein provided, the Company shall promptly give to each
Holder notice of such adjustment or adjustments and shall promptly deliver to
each Holder and the Warrant Agent an Officer's Certificate (confirmed by a
certificate from the Company's independent certified public accountants) setting
forth: (i) the number of Warrant Shares issuable upon the exercise of each
Warrant and the Purchase Price of such shares after such adjustment; (ii) a
brief statement of the facts requiring such adjustment; and (iii) the
computation by which such adjustment was made.

                  So long as any Warrant is outstanding, within ninety (90) days
of the end of each fiscal year of the Company, the Company shall deliver to each
Holder an Officer's Certificate setting forth: (i) the number of Warrant Shares
issuable upon the exercise of each Warrant and the Exercise Price of such shares
as of the end of such fiscal year; (ii) a brief statement of the facts requiring
each adjustment, if any, required to be made in such fiscal year; and (iii) the
computation by which each such adjustment was made.

                         CONCERNING THE WARRANT AGENT

                  SECTION 6.1.  Warrant Agent. At no time when the Company may
                                -------------
be acting as its own Warrant Agent shall any of its obligations to the Holders
be in any respect reduced as a result thereof. The Warrant Agent shall have the
powers and authority specifically granted to and conferred upon it in the
Warrant Certificates and this Warrant Agreement and such further powers and
authority to act on behalf of the Company as the Company may hereafter grant to
or confer upon it and it shall accept in writing. All of the terms and
provisions with respect to such powers

                                       19
<PAGE>

and authority contained in the Warrant Certificates are subject to and governed
by the terms and provisions hereof.

                  SECTION 6.2.  Conditions of Warrant Agent's Obligations. The
                                -----------------------------------------
Warrant Agent accepts its obligations herein set forth upon the terms and
conditions hereof and in the Warrant Certificates, including the following, to
all of which the Company agrees and to all of which the rights hereunder of the
Holders from time to time of the Warrant Certificates shall be subject:

                  (a)  The Warrant Agent shall be entitled to compensation to be
agreed upon in a separate fee agreement with the Company in writing for all
services rendered by it and the Company agrees promptly to pay such compensation
and to reimburse the Warrant Agent for its reasonable out-of-pocket expenses
(including reasonable fees and expenses of counsel) incurred without gross
negligence, bad faith or willful misconduct on its part in connection with the
services rendered by it hereunder. The Company also agrees to indemnify the
Warrant Agent, each predecessor Warrant Agent, and their respective directors,
officers, affiliates, agents and employees for, and to hold it and its
directors, officers, affiliates, agents and employees harmless against, any
loss, liability or expense of any nature whatsoever (including, without
limitation, fees and expenses of counsel) incurred without gross negligence, bad
faith or willful misconduct on the part of the Warrant Agent or predecessor
Warrant Agent, arising out of or in connection with its acting as such Warrant
Agent hereunder and its exercise or failure to exercise of its rights and
performance of its obligations hereunder. The obligations of the Company under
this Section 6.2 shall survive the exercise and the expiration of the Warrant
     -----------
Certificates and the resignation and removal of the Warrant Agent.

                  (b)  In acting under this Warrant Agreement and in connection
with the Warrant Certificates, the Warrant Agent is acting solely as agent of
the Company and does not assume any obligation or relationship of agency or
trust for or with any of the owners or Holders of the Warrant Certificates.

                  (c)  The Warrant Agent may consult with counsel and any advice
or written opinion of such counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with such advice or opinion.

                  (d)  The Warrant Agent shall be fully protected and shall
incur no liability for or in respect of any action taken or omitted to be taken
or thing suffered by it in reliance upon any Warrant Certificate, notice,
direction, consent, certificate, affidavit, opinion of counsel, instruction,
statement or other paper or document reasonably believed by it to be genuine and
to have been presented or signed by the proper parties.

                  (e)  The Warrant Agent and its Related Parties may become the
owners of, or acquire any interest in, Warrant Certificates, shares or other
obligations of the Company with the same rights that it or they would have it if
were not the Warrant Agent hereunder and, to the extent permitted by applicable
law, it or they may engage or be interested in any financial or other
transaction with the Company and may act on, or as depositary, trustee or agent
for, any committee or body of holders of shares or other obligations of the
Company as freely as if it were not the

                                       20
<PAGE>

Warrant Agent hereunder. Nothing in this Warrant Agreement shall be deemed to
prevent the Warrant Agent or such Related Parties from acting in any other
capacity for the Company.

                  (f)  The Warrant Agent shall not be under any liability for
interest on, and shall not be required to invest, any money at any time received
by it pursuant to any of the provisions of this Warrant Agreement or of the
Warrant Certificates.

                  (g)  The Warrant Agent shall not be under any responsibility

hereof) or the execution and delivery hereof or in respect of the validity or
execution of any Warrant Certificate (except its authentication thereof).

                  (h)  The recitals and other statements contained herein and in
the Warrant Certificates (except as to the Warrant Agent's authentication
thereon) shall be taken as the statements of the Company, and the Warrant Agent
assumes no responsibility for the correctness of such recitals or other
statements. The Warrant Agent does not make any representation as to the
validity or sufficiency of this Warrant Agreement or the Warrant Certificates;
provided, however, that the Warrant Agent shall not be relieved of its duty to
authenticate the Warrant Certificates as authorized by this Warrant Agreement.
The Warrant Agent shall not be accountable for the use or application by the
Company of the proceeds of the exercise of any Warrant.

                  (i)  Before the Warrant Agent acts or refrain from acting with
respect to any matter contemplated by this Warrant Agreement, it may require:

                       (A) an Officers' Certificate stating that, in the opinion
                  of the signers, all conditions precedent, if any, provided for
                  in this Warrant Agreement relating to the proposed action have
                  been complied with; and

                       (B) if reasonably necessary in the sole judgment of the
                  Warrant Agent, an opinion of counsel for the Company stating
                  that, in the opinion of such counsel, all such conditions
                  precedent have been complied with.

                  Each Officers' Certificate or, if requested, an opinion of
counsel (with respect to which such counsel may rely, as to matters of fact, on
a certificate or certificates of Officers of the Company) with respect to
compliance with a condition or covenant provided for in this Warrant Agreement
shall include:

                           (1) a statement that the Person making such
         certificate or opinion has read such covenant or condition;

                           (2) a brief statement as to the nature and scope of
         the examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                           (3) a statement that, in the opinion of such Person,
         he or she has made such examination or investigation as is necessary to
         enable him or her to

                                       21
<PAGE>

         express an informed opinion as to whether or not such covenant or
         condition has been complied with; and

                           (4) a statement as to whether or not, in the opinion
         of such Person, such condition or covenant has been complied with.

                  (j)  The Warrant Agent shall be obligated to perform such
duties as are specifically set forth herein and in the Warrant Certificates and
no implied duties or obligations shall be read into this Warrant Agreement or
the Warrant Certificates against the Warrant Agent. The Warrant Agent shall not
be accountable or under any duty or responsibility for the use by the Company of
any of the Warrant Certificates authenticated by the Warrant Agent and delivered
by it to the Company pursuant to this Warrant Agreement. The Warrant Agent shall
have no duty or responsibility in case of any default by the Company in the
performance of its covenants or agreements contained in the Warrant Certificates
or in the case of the receipt of any written demand from a Holder with respect
to such default, including, without limiting the generality of the foregoing,
any duty or responsibility to initiate or attempt to initiate any proceedings at
law or otherwise or, except as provided in Section 7.2 hereof, to make any
                                           -----------
demand upon the Company. The Warrant Agent shall not be obligated to perform any
duty to the extent prohibited by law.

                  (k)  Unless otherwise specifically provided herein, any order,
certificate, notice, request, direction or other communication from the Company
made or given under any provision of this Warrant Agreement shall be sufficient
if signed by its President or, Vice President and attested by its Treasurer,
Controller, Secretary or any Assistant Secretary.

                  (l)  The Warrant Agent shall have no responsibility in respect
of any adjustment pursuant to Article V hereof.
                              ---------

                  (m)  The Company agrees that it will perform, execute,
acknowledge and deliver, or cause to be performed, executed, acknowledged and
delivered, all such further and other acts, instruments and assurances as may
reasonably be required by the Warrant Agent for the carrying out or performing
by the Warrant Agent of the provisions of this Warrant Agreement.

                  (n)  The Warrant Agent is hereby authorized and directed to
accept written instructions with respect to the performance of its duties
hereunder from any one of the President, the Treasurer, the Controller, any Vice
President or the Secretary of the Company or any other officer or official of
the Company reasonably believed to be authorized to give such instructions and
to apply to such officers or officials for advice or instructions in connection
with its duties, and it shall not be liable for any action taken or suffered to
be taken by it in good faith in accordance with instructions with respect to any
matter arising in connection with the Warrant Agent's duties and obligations
arising under this Warrant Agreement. Such application by the Warrant Agent for
written instructions from the Company may, at the option of the Warrant Agent,
set forth in writing any action proposed to be taken or omitted by the Warrant
Agent with respect to its duties or obligations under this Warrant Agreement and
the date on or after which such action shall be taken, and the Warrant Agent
shall not be liable for any action taken or omitted to be taken in accordance
with a proposal included in any such application on or after the date specified
therein (which date shall be not less than 10 Business Days after the Company
receives such application unless the Company consents to a shorter period),
provided that (i) such application includes a statement to

                                       22
<PAGE>

the effect that it is being made pursuant to this Section 6.2(n) and that unless
                                                  --------------
objected to prior to such date specified in the application, the Warrant Agent
will not be liable for any such action or omission to the extent set forth in
such application and (ii) prior to taking or omitting any such action, the
Warrant Agent has not received written instructions objecting to such proposed
action or omission.

                  (o)  Whenever in the performance of its duties under this
Warrant Agreement the Warrant Agent shall deem it necessary or desirable that
any fact or matter be proved or established by the Company prior to taking or
suffering any action hereunder, such fact or matter (unless other evidence in
respect thereof be herein specifically prescribed) may be deemed to be
conclusively proved and established by a certificate signed by any one of the
President, the Treasurer, the Controller, any Vice President or the Secretary of
the Company or any other officer or official of the Company reasonably believed
by the Warrant Agent to be authorized to give such instructions and delivered to
the Warrant Agent and such certificate shall grant full authorization to the
Warrant Agent for any action taken or suffered in good faith by it under the
provisions of this Warrant Agreement in reliance upon such certificate.

                  (p)  The Warrant Agent shall not be required to risk or expend
its own funds in the performance of its obligations and duties hereunder.

                  SECTION 6.3.      Resignation and Appointment of Successor.
                                    ----------------------------------------

                  (a)  The Company agrees, for the benefit of the Holders, that
there shall at all times be a Warrant Agent hereunder.

                  (b)  The institution serving as Warrant Agent may at any time
resign as Warrant Agent by giving written notice to the Company of such
intention on its part, specifying the date on which its desired resignation
shall become effective, provided that such date shall be at least 30 days after
the date on which such notice is given unless the Company agrees to accept less
notice. Upon receiving such notice of resignation, or in the event the Company
shall determine not to continue to act as its own Warrant Agent, the Company
shall promptly appoint a successor Warrant Agent, qualified as provided in
Section 6.3(d) hereof, by written instrument in duplicate signed on behalf of
--------------
the Company, one copy of which shall be delivered to the resigning Warrant Agent
and one copy to the successor Warrant Agent. As provided in Section 6.3(d)
                                                            --------------
hereof, such resignation shall become effective upon the earlier of (x) the
acceptance of the appointment by the successor Warrant Agent or (y) 30 days
after receipt by the Company of notice of such resignation. The Company may, at
any time and for any reason, and shall, upon any event set forth in the next
succeeding sentence, remove the Warrant Agent and appoint a successor Warrant
Agent by written instrument in duplicate, specifying such removal and the date
on which it is intended to become effective, signed on behalf of the Company,
one copy of which shall be delivered to the Warrant Agent being removed and one
copy to the successor Warrant Agent. The Warrant Agent shall be removed as
aforesaid if it shall become incapable of acting, or shall be adjudged a
bankrupt or insolvent, or a receiver of the Warrant Agent or of its property
shall be appointed, or any public officer shall take charge or control of it or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation. Any removal of the Warrant Agent and any appointment of a successor
Warrant Agent shall become effective upon acceptance of appointment by the
successor Warrant Agent as provided in Section 6.3(d). As soon as practicable
                                       --------------
after appointment of the

                                       23
<PAGE>

successor Warrant Agent, the Company shall cause written notice of the change in
the Warrant Agent to be given to each of the registered Holders in the manner
provided for in Section 7.4 hereof.
                -----------

                  (c)  Upon resignation or removal of the Warrant Agent, if the
Company shall fail to appoint a successor Warrant Agent within a period of 30
days after receipt of such notice of resignation or removal, then the Holder or
the Warrant Agent may apply to a court of competent jurisdiction for the
appointment of a successor to the Warrant Agent. Pending appointment of a
successor to the Warrant Agent, either by the Company or by such a court, the
duties of the Warrant Agent shall be carried out by the Company.

                  (d)  Any successor Warrant Agent, whether appointed by the
Company or by a court, shall be a bank or trust company in good standing,
incorporated under the laws of the United States of America or any State thereof
and having, at the time of its appointment, a combined capital surplus of at
least $200 million. Such successor Warrant Agent shall execute and deliver to
its predecessor and to the Company an instrument accepting such appointment
hereunder and all the provisions of this Warrant Agreement, and thereupon such
successor Warrant Agent, without any further act, deed or conveyance, shall
become vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as Warrant Agent
hereunder, and such predecessor shall thereupon become obligated to (i) transfer
and deliver, and such successor Warrant Agent shall be entitled to receive, all
securities, records or other property on deposit with or held by such
predecessor as Warrant Agent hereunder and (ii) upon payment of the amounts then
due it pursuant to Section 6.2(a) hereof, pay over, and such successor Warrant
                   --------------
Agent shall be entitled to receive, all money deposited with or held by any
predecessor Warrant Agent hereunder.

                  (e)  Any corporation or bank into which the Warrant Agent
hereunder may be merged or converted, or any corporation or bank with which the
Warrant Agent may be consolidated, or any corporation or bank resulting from any
merger, conversion or consolidation to which the Warrant Agent shall be a party,
or any corporation or bank to which the Warrant Agent shall sell or otherwise
transfer all or substantially all of its corporate trust business or assets,
shall be the successor to the Warrant Agent under this Warrant Agreement
(provided that such corporation or bank shall be qualified as aforesaid) without
the execution or filing of any document or any further act on the part of any of
the parties hereto.

                  (f)  No Warrant Agent under this Warrant Agreement shall be
personally liable for any action or omission of any successor Warrant Agent or
of the Company.

         THIS SECURITY IS SUBJECT TO A REGISTRATION RIGHTS AGREEMENT DATED AS OF
APRIL 12, 2001 BETWEEN THE COMPANY AND BOEING CAPITAL LOAN CORPORATION (THE
"INITIAL PURCHASER"), A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE
COMPANY.

No. ATH-1                                                       166,400 Warrants
                              WARRANT CERTIFICATE

                            AIRTRAN HOLDINGS, INC.

                  This Warrant Certificate certifies that Boeing Loan
Corporation, or registered assigns, is the registered holder (the "Holder") of
166,400 Warrant(s) (the "WARRANT(S)") to purchase shares of Common Stock, $0.001
par value per share (the "COMMON STOCK"), of AIRTRAN HOLDINGS, INC., a Nevada
corporation (the "COMPANY"). Each Warrant entitles the Holder to purchase from
the Company at any time from 9:00 a.m. New York City time on or after the
Exercisability Date (as defined in the Warrant Agreement) until 5:00 p.m., New
York City time, on April 12, 2006 (the "EXPIRATION DATE"), 18.02885 fully paid
and nonassessable shares of Common Stock (as may be adjusted, the "WARRANT
SHARES", and which may also include any other securities or property purchasable
upon exercise of a Warrant, such adjustment and inclusion each as provided in
the Warrant Agreement) at the exercise price (the "EXERCISE PRICE") of $4.51 per
Warrant Share upon surrender of this Warrant Certificate and payment of the
Exercise Price at any office or agency maintained for that purpose by the
Company (the "WARRANT AGENT OFFICE"), subject to the conditions set forth herein
and in the Warrant Agreement. Notwithstanding the foregoing, in the event that
any Holder of Warrant Certificates delivers such Warrant Certificates to the
Company and indicates on the Election to Exercise that such Holder intends to
exercise all, or any portion of, the Warrants represented by such Warrant
Certificate to satisfy its obligation to pay the Exercise, such Holder shall be
entitled to receive, a number of Warrant Shares in respect of the exercise of
such Warrants equal to the product of: (A) the number of Warrant Shares issuable
                           ----------
upon the exercise of such Warrant Certificates (or, if only a portion of such
Warrant Certificates are being exercised, issuable upon the exercise of such
portion) multiplied by (B) the quotient of: (i) the difference between: (X) the
         -------------         -----------          ----------
per share Fair Market Value of the Common Stock at the time of such exercise;
minus (Y) the Exercise Price at the time of such exercise; divided by (ii) the
-----                                                      ----------
per share Fair Market Value of the Common Stock at the time of such exercise. An
exercise of a Warrant in accordance with the immediately preceding sentences is
herein called a "CASHLESS EXERCISE."

                  To the extent an exercise of a Warrant is not effected through
a Cashless Exercise, the Exercise Price shall be payable by certified check or
official bank check or by such other means as is acceptable to the Company in
the lawful currency of the United States of America which as of the time of
payment is legal tender for payment of public or private debts. The Company has
initially designated the principal corporate trust office of the Warrant Agent
in The City of Wilmington, Delaware, as the initial Warrant Agent Office. The
Exercise Price and the number and kind of Warrant Shares purchasable upon the
exercise of the Warrants is subject to adjustment upon the occurrence of certain
events set forth in the Warrant Agreement.

                  Any Warrants not exercised on or prior to 5:00 p.m., New York
City time, on April 12, 2006 shall expire and thereafter be void.

                  Reference is hereby made to the further provisions on the
reverse hereof which provisions shall for all purposes have the same effect as
though fully set forth at this place.

Agreement.

                  All terms used herein but not defined herein have the meanings
ascribed to such terms in the warrant agreement.

                  THIS WARRANT CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS
PROVISIONS THEREOF.

                            AIRTRAN HOLDINGS, INC.

                  The Warrants evidenced by this Warrant Certificate are part of
a duly authorized issue of Warrants expiring at 5:00 p.m., New York City time,
on April 12, 2006, each of which represents the right to purchase at any time on
or after the Exercisability Date (as defined in the Warrant Agreement) and on or
prior to such date 18.02885 shares of Common Stock of the Company, subject to
adjustment as set forth in the Warrant Agreement. The Warrants are issued
pursuant to a Warrant Agreement dated as of April 12, 2001 (the "WARRANT
AGREEMENT"), duly executed and delivered by the Company to Wilmington Trust
Company, as Warrant Agent (the "WARRANT AGENT"), which Warrant Agreement is
hereby incorporated by reference in and made a part of this instrument and is
hereby referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Warrant Agent, the Company
and the Holders (the words "Holders" or "Holder" meaning the registered Holder
or registered Holders) of the Warrants.

                  Warrants may be exercised by (i) surrendering at any Warrant
Agent Office this Warrant Certificate with the form of Election to Exercise set
forth hereon duly completed and executed and (ii) to the extent such exercise is
not being effected through a Cashless Exercise, paying in full the Warrant
Exercise Price for each such Warrant exercised and any other amounts required to
be paid pursuant to the Warrant Agreement.

                  If all of the items referred to in the last sentence of the
preceding paragraph are received by the Warrant Agent at or prior to 2:00 p.m.,
New York City time, on a Business Day, the exercise of the Warrant to which such
items relate will be effective on such Business Day. If any items referred to in
the last sentence of the preceding paragraph are received after 2:00 p.m., New
York City time, on a Business Day, the exercise of the Warrants to which such
item relates will be deemed to be effective on the next succeeding Business Day.
Notwithstanding the foregoing, in the case of an exercise of Warrants on April
12, 2006, if all of the items referred to in the last sentence of the preceding
paragraph are received by the Warrant Agent at or prior to 5:00 p.m., New York
City time, on such Expiration Date, the exercise of the Warrants to which such
items relate will be effective on the Expiration Date.

                  As soon as practicable after the exercise of any Warrant or
Warrants, but in no event later than the third business day after the Exercise
Date, the Company shall issue or cause to be issued to or upon the written order
of the registered Holder of this Warrant Certificate, a certificate or
certificates evidencing the Warrant Shares to which such Holder is entitled, in
fully registered form, registered in such name or names as may be directed by
such Holder pursuant to the Election to Exercise, as set forth on the reverse of
this Warrant Certificate. Such certificate or certificates evidencing the
Warrant Shares shall be deemed to have been issued and any persons who are
designated to be named therein shall be deemed to have become the Holder of
record of such Warrant Shares as of the close of business on the Exercise Date.
After such exercise of any Warrant or Warrants, the Company shall also issue or
cause to be issued to or upon the written order of the registered Holder of such
Warrant Certificate, a new Warrant Certificate, countersigned by the Warrant
Agent pursuant to the Company's written instruction, evidencing the number of
Warrants, if any, remaining unexercised (unless such Warrants shall have
expired).

                  The Company shall not be required to issue fractional shares
of Common Stock on the exercise of Warrants. If more than one Warrant shall be
presented for exercise in full at the same time by the same Holder, the number
of full shares of Common Stock which shall be issuable upon such exercise shall
be computed on the basis of the aggregate number of shares of Common Stock which
may be acquired on exercise of the Warrants so presented. If any fraction of a
share of Common Stock would be issuable on the exercise of any Warrant or
Warrants, the Company shall either (i) pay an amount in cash calculated by the
Company to equal the per share Fair Market Value of the Common Stock multiplied
by

                                       4
<PAGE>

such fraction of a share of Common Stock computed to the nearest whole cent or
(ii) aggregate all such fractional shares of Common Stock into a whole number of
shares and sell such aggregated fractional shares on behalf of the Holders
entitled thereto in a public or private sale and distribute, on a pro rata
basis, the net cash proceeds therefrom to such Holders. While the Company will
use its best efforts to secure the best available sale price for such aggregated
fractional shares, such price shall not necessarily be the highest price
obtainable for such shares. By their acceptances of the Warrant Certificates,
Holders expressly waive any and all rights to receive any fraction of a share of
Common Stock or a stock certificate or scrip representing a fraction of a share
of Common Stock.

                  Warrant Certificates, when surrendered at any office or agency
maintained by the Company for that purpose by the registered Holder thereof in
person or by legal representative or attorney duly authorized in writing, may be
exchanged for a new Warrant Certificate or new Warrant Certificates evidencing
in the aggregate a like number of Warrants, in the manner and subject to the
limitations provided in the Warrant Agreement, without charge except for any tax
or other governmental charge imposed in connection therewith.

                  Upon due presentment for registration of transfer of this
Warrant Certificate at any office or agency maintained by the Company for that
purpose, a new Warrant Certificate evidencing in the aggregate a like number of
Warrants shall be issued to the transferee in exchange for this Warrant
Certificate, subject to the limitations provided in the Warrant Agreement,
without charge except for any tax or other governmental charge imposed in
connection therewith.

                  The Company and the Warrant Agent may deem and treat the
registered Holder hereof as the absolute owner of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by
anyone) for the purpose of any exercise hereof and for all other purposes, and
neither the Company nor the Warrant Agent shall be affected by any notice to the
contrary.
