                                          September 5, 2001


Dear Shareholder:


    This Notice of Adjourned Annual Meeting and amended and restated proxy
statement dated September 5, 2001 is being distributed to you in connection with
the adjourned annual meeting which will be reconvened at 8:00 a.m. on
October 10, 2001 and replaces entirely the previously mailed Notice of Annual
Meeting of Shareholders and proxy statement dated April 16, 2001, for our annual
meeting of shareholders on Tuesday, May 29, 2001. The May 29, 2001 meeting was
convened as planned and adjourned to a later date, which has been set by the
board of directors as stated above.


    As described in the attached proxy statement, at the annual meeting you will
be asked to consider and vote upon the merger of INDUS Acquisition Company
('INDUS'), an Indiana corporation owned by J. George Mikelsons ('Mikelsons'),
with and into Amtran, Inc. ('Amtran'), pursuant to a plan of merger, attached as
Exhibit A to the Agreement and Plan of Merger dated as of June 18, 2001, which
is attached as Annex A to the accompanying proxy statement. Upon consummation of
the merger, each outstanding share of our common stock, without par value, other
than shares owned by us, Mikelsons, INDUS or any affiliate of Mikelsons who is
not deemed to be an affiliate of Mikelsons by reason of their position as an
officer or director of Amtran (the 'Mikelsons Affiliates'), will be converted
into the right to receive $23 in cash, without interest, upon valid surrender of
the certificate formerly representing that share. In connection with the merger,
holders of shares of our common stock and Series B preferred stock, without par
value, voting as separate classes, will be asked to approve a proposal to amend
and restate Article XII of our Articles of Incorporation to modify the terms of
our Series B preferred stock (the 'ILFC Amendment') pursuant to the Purchase and
Voting Agreement dated as of May 16, 2001 (the 'ILFC Agreement'), between
International Lease Finance Corporation ('ILFC') and us. The ILFC Agreement is
attached as Annex B to the accompanying proxy statement. Approval of the ILFC
Amendment is a condition to the merger.

    YOUR BOARD OF DIRECTORS, ACTING ON THE RECOMMENDATION OF THE SINGLE MEMBER
SPECIAL INDEPENDENT DIRECTOR COMMITTEE OF AMTRAN, HAS DETERMINED THAT THE MERGER
IS FAIR TO AND IN THE BEST INTERESTS OF AMTRAN AND THE HOLDERS OF SHARES OF OUR
COMMON STOCK OTHER THAN MIKELSONS AND ANY MIKELSONS AFFILIATE. THE BOARD OF
DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE 'FOR' APPROVAL OF THE MERGER, THE
PLAN OF MERGER, THE MERGER AGREEMENT AND THE ILFC AMENDMENT.

    Among the factors considered by a single member special independent director
committee in evaluating the merger was the opinion dated June 18, 2001, of
Dresdner Kleinwort Wasserstein, Inc. ('DrKW'), the financial advisor to the
single member special independent director committee, which states that as of
such date, the $23.00 per share cash consideration to be received by the holders
of shares of our common stock other than Mikelsons and any Mikelsons Affiliate
pursuant to the merger is fair to such shareholders from a financial point of
view. The written opinion of DrKW is attached as Annex C to the accompanying
proxy statement, and you should read it carefully and in its entirety.

    Completion of the merger is subject to certain conditions, including
approval of the merger, the plan of merger and the merger agreement by the
affirmative vote of the holders of a majority of the outstanding shares of our
common stock entitled to vote at the annual meeting, including the affirmative
vote of the holders of a majority of the outstanding shares voting thereon not
owned by Mikelsons or any Mikelsons Affiliate and the approval of the ILFC
Amendment by the affirmative vote of the holders of a majority of the
outstanding shares of our common stock and our Series B preferred stock, voting
as separate classes.

    Your board of directors has specified August 20, 2001 as the new record date
for the purposes of determining the shareholders who are entitled to receive
notice of and to vote at the annual meeting. IN ORDER TO VOTE BY PROXY AT THE
ANNUAL MEETING, YOU MUST USE THE ENCLOSED YELLOW PROXY CARD TO VOTE AT THE
ANNUAL MEETING EVEN IF YOU PREVIOUSLY SUBMITTED A BLUE PROXY CARD FOR THE ANNUAL
MEETING SCHEDULED FOR MAY 29, 2001. PLEASE DISREGARD ANY BLUE PROXY CARDS WE
HAVE PREVIOUSLY SENT YOU. As of September 5, 2001, Mikelsons was the record
owner of 8,271,200 shares of common stock (or approximately 72% of the
outstanding shares of our common stock on that date). In addition, other
directors and executive officers of Amtran (none of whom is a Mikelsons
Affiliate) beneficially owned 1,300,467 shares of common stock consisting of
84,762 shares of common stock (which represented on that date less than 1% of
the outstanding shares and approximately 2.6% of the outstanding shares not
owned by Mikelsons or any Mikelsons Affiliate), presently exercisable options to
purchase 1,214,689 shares of common stock and 1,010 shares of our common stock
allocated to such directors and executive officers under the American Trans Air,
Inc. Employees' Salary Savings Plan. To our knowledge, these directors and
officers intend to vote the 85,772 shares of our common stock which they have
the power to direct the voting of in favor of all items presented at the annual
meeting.


    You will also be asked to vote upon the election of a board of directors for
the ensuing year and until their successors are elected and qualified and upon
the ratification of the selection of Ernst & Young, LLP as independent
accountants for the fiscal year ending December 31, 2001.

    On the following pages, you will find a Notice of the Adjourned Annual
Meeting and an amended and restated proxy statement, which provide you with
detailed information concerning the merger and other matters to be voted upon.
We urge you to read these materials carefully and request that you promptly
complete and return the enclosed YELLOW proxy card. If you attend the annual
meeting, you may vote in person even if you have previously returned your proxy
card. Your vote is important regardless of the number of shares of our common
stock you own.

                                          Sincerely,

                                          Board of Directors of Amtran, Inc.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS: APPROVED OR DISAPPROVED OF THE MERGER; PASSED UPON THE MERITS OR
FAIRNESS OF THE MERGER; OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE
DISCLOSURE IN THE ACCOMPANYING AMENDED AND RESTATED PROXY STATEMENT. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.


THIS AMENDED AND RESTATED PROXY STATEMENT IS DATED SEPTEMBER 5, 2001, AND IS
BEING FIRST MAILED TO AMTRAN SHAREHOLDERS ON OR ABOUT SEPTEMBER 7, 2001.

    Mikelsons, or any affiliate of Mikelsons who is not deemed to be an
    affiliate of Mikelsons by reason of being an officer or director of Amtran

    ('ILFC'). Holders of shares of Amtran's common stock and Series B preferred
    stock, without par value, voting as separate classes, are entitled to vote
    on the ILFC Amendment, which would change the terms of the Series B

    merger agreement.

        3. To elect six directors: J. George Mikelsons, John P. Tague, Kenneth
    K. Wolff, James W. Hlavacek, Robert A. Abel and Andrejs P. Stipnieks, each

        4. To ratify the selection of Ernst & Young, LLP as independent
    accountants for Amtran for the fiscal year ending December 31, 2001.

        5. To transact such other business as may properly come before the
    annual meeting or any adjournments thereof.

    The board of directors has specified August 20, 2001 as the new record date
for the purpose of determining the shareholders who are entitled to receive
notice of and to vote at the annual meeting. Only holders of record of shares of
our common stock and Series B preferred stock at the close of business on that

                      AMENDED AND RESTATED PROXY STATEMENT
                               SUMMARY TERM SHEET

    This summary term sheet highlights the material terms of the proposed merger
and the related transactions described in this proxy statement but may not
contain all information that is important to you. We encourage you to read this
entire document carefully and the documents which are referred to in this
document. All references in this proxy statement to the 'annual meeting' mean
the adjourned annual meeting to be held as described in this proxy statement.

                                  THE PARTIES

AMTRAN


    Amtran, Inc., an Indiana corporation, owns American Trans Air, Inc., an
Indiana corporation which we will refer to as ATA, the eleventh largest
passenger airline in the United States (based on passenger revenue miles) and a
leading provider of airline services in selected markets. ATA is also the
largest commercial charter airline in the United States and the largest provider
of passenger airline services to the United States military, in each case based
on 2000 revenues. For the year ended December 31, 2000, the revenues of ATA
consisted of 58.3% scheduled service, 19.1% commercial charter service and 14.6%
military charter service, with the balance derived from related services. Amtran
expects to increase substantially the portion of its revenues that is derived
from scheduled service and reduce its emphasis on commercial charter services.
See 'The Parties' (page 44).


INDUS


    INDUS Acquisition Company, an Indiana corporation, was organized to merge
with us and has not conducted any unrelated activities since its organization
and will cease to exist after the merger. INDUS is wholly owned by J. George
Mikelsons, Amtran's founder and majority shareholder. See 'The Parties'
(page 45).


MIKELSONS


    Mikelsons is the founder and majority shareholder of Amtran. His principal
occupation is as the Chairman of Amtran. He is also the sole shareholder of
INDUS, the sole member of the board of directors of INDUS and the sole officer
(Chairman and President) of INDUS. See 'The Parties' (page 45) and 'Election of
Directors -- Nominees' (page 57).


TAGUE, WOLFF AND HLAVACEK


    John P. Tague is the Chief Executive Officer of Amtran, Kenneth K. Wolff is
the Executive Vice President and Chief Financial Officer of Amtran and James W.
Hlavacek is the Executive Vice President and Chief Operating Officer of Amtran.
Each of these officers are also members of the board of directors of Amtran. The
options to purchase shares of our common stock held by each of these officers
will remain outstanding following the merger. We use the term filing persons in
this proxy statement to refer to these three officers, Mikelsons and INDUS,
collectively. See 'The Parties' (page 46) and 'Election of
Directors -- Nominees' (page 57).


                               THE ANNUAL MEETING

DATE, PLACE AND TIME


    The annual meeting will be reconvened at 8:00 a.m., local time, on
October 10, 2001, at our headquarters, at 7337 West Washington Street,
Indianapolis, Indiana. See 'The Annual Meeting' (page 4).


                                       i

PURPOSE OF THE ANNUAL MEETING

    At the annual meeting, you will be asked to:

     approve the merger between INDUS and us, the plan of merger and the merger
     agreement;

     approve the amendment and restatement of Article XII of our Articles of
     Incorporation, which modifies the terms of our Series B preferred stock,
     pursuant to the Purchase and Voting Agreement dated as of May 16, 2001,
     between us and International Lease Finance Corporation ('ILFC'), which we
     will refer to as the ILFC amendment;

     vote for the election of directors of Amtran to serve until the next annual
     meeting of shareholders; and

     ratify the selection of Ernst & Young, LLP as independent accountants for
     the fiscal year ending December 31, 2001.


    See 'The Annual Meeting' (page 4).


Approval of the ILFC amendment by holders of shares of our common stock and
Series B preferred stock, voting as separate classes, is a condition to the
merger.

RECORD DATE


    Your board of directors has fixed the close of business on August 20, 2001,
as the new record date for the determination of holders of shares of our common
stock and Series B preferred stock entitled to notice of the annual meeting and
entitled to vote at the annual meeting. On the record date, there were
11,501,079 shares of our common stock and 300 shares of Series B preferred stock
outstanding and entitled to vote at the annual meeting. See 'The Annual Meeting'
(page 4).


VOTE REQUIRED

    Under the Indiana Business Corporation Law or the merger agreement, the
following votes are required to approve the matters submitted to the annual
meeting:

APPROVAL OF THE MERGER AND RELATED MATTERS

     the affirmative vote of the holders of a majority of the outstanding shares
     of our common stock entitled to vote at the annual meeting to approve the
     merger, the plan of merger and the merger agreement; failures to vote and

     the affirmative vote of the holders of a majority of the shares of our
     common stock not owned by Mikelsons or any Mikelsons Affiliate voting at
     the annual meeting to approve the merger, the plan of merger and the merger
     agreement; in this proxy statement we use the term 'Mikelsons Affiliate' to
     mean any affiliate of Mikelsons who is not deemed to be an affiliate of
     Mikelsons by reason of being an officer or director of Amtran (the only
     person or entity who may be a Mikelsons Affiliate and who owns or has the
     right to acquire shares of Amtran common stock is INDUS); failures to vote
     and abstentions will have no effect on whether this approval is obtained;

     of our Series B preferred stock, voting as a separate class, to approve the
     ILFC amendment; a failure to vote or an abstention by ILFC (the sole holder
     of our Series B preferred stock) would count as a vote against the ILFC
     amendment; ILFC has agreed to vote all its shares in favor of the ILFC
     amendment and has granted an irrevocable proxy to Kenneth K. Wolff and
     James W. Hlavacek to vote its shares of our Series B preferred stock with
     respect to the ILFC amendment.

                                       ii

<Page>
ELECTION OF DIRECTORS

     a plurality of the votes cast by holders of shares of common stock entitled
     to vote to elect new directors to serve until the next annual meeting of
     shareholders; failures to vote and abstentions will have no effect on the
     election of directors; Mikelsons, as the owner of approximately 72% of the
     outstanding shares of our common stock, has sufficient voting power to
     ensure the election of the nominees for director.

RATIFICATION OF THE SELECTION OF ERNST & YOUNG

     more votes are cast in favor than are cast against the ratification of the
     selection of Ernst & Young, LLP as independent accountants for the fiscal
     year ending December 31, 2001; failures to vote and abstentions will have
     no effect on the ratification of the selection of Ernst & Young; Mikelsons,
     as the owner of approximately 72% of the outstanding shares of our common

     selection of Ernst & Young.

                                SPECIAL FACTORS

PURPOSE AND STRUCTURE OF THE MERGER


    The purpose of the merger is for Mikelsons to own all the common stock of
Amtran immediately following completion of the merger (other than shares of our
common stock which may be issued in the future upon the exercise of stock
options or the conversion of shares of our Series B preferred stock). As further
described in 'Special Factors -- Purpose and Structure of the Merger', Amtran
and the filing persons believe that taking Amtran private at this time will
allow management to focus on the implementation of long-term strategic
initiatives. Amtran, INDUS and Mikelsons structured this transaction as a cash
merger between Amtran and INDUS in order to achieve this result in a single
transaction. While Mikelsons consulted with the other filing persons regarding
various matters, all decisions relating to the price to be paid and the other
principal features of the merger were made by Mikelsons. See 'Special
Factors -- Purpose and Structure of the Merger' (page 16).


                                      iii

RECOMMENDATIONS OF THE SINGLE MEMBER SPECIAL INDEPENDENT DIRECTOR COMMITTEE AND
THE BOARD OF DIRECTORS

    On June 18, 2001, a special independent director committee, consisting of
the sole independent member of your board of directors for the purpose of
evaluating this transaction, determined that the merger is fair to and in the
best interests of Amtran and the holders of shares of our common stock (other
than Mikelsons and any Mikelsons Affiliate).


    Your board of directors, based on, among other things, the recommendation of
the single member special independent director committee, unanimously approved
the merger, the merger agreement, the ILFC agreement and the ILFC amendment and
adopted the plan of merger, determined that the merger is fair to and in the
best interests of Amtran and the holders of shares of our common stock (other
than Mikelsons and any Mikelsons Affiliate) and recommended that holders of
shares of our common stock (including a majority of shares voting at the annual
meeting not owned by Mikelsons or any Mikelsons Affiliates) approve the merger,
the plan of merger, the merger agreement and the ILFC amendment. See 'Special
Factors -- Recommendations of the Single Member Special Independent Director
Committee and the Board of Directors' (page 17).


FAIRNESS OF THE MERGER


    For the reasons set forth in 'Special Factors -- Fairness of the Merger',
the single member special independent director committee and your board of
directors concluded that the merger is fair to and in the best interests of
Amtran and the holders of shares of our common stock (other than Mikelsons and
any Mikelsons Affiliate). See 'Special Factors -- Fairness of the Merger'
(page 18).


OPINION OF FINANCIAL ADVISOR TO THE SINGLE MEMBER SPECIAL INDEPENDENT DIRECTOR
COMMITTEE


    This summary is not a complete description of the analysis performed by
Dresdner Kleinwort Wasserstein, Inc., which we will refer to as DrKW, and is
qualified by reference to the written opinion of DrKW set forth in Annex C to
this proxy statement.


    DrKW, which served as financial advisor to the single member special
independent director committee, has delivered a written opinion, dated June 18,
2001, to the single member special independent director committee that, as of
the date of the opinion and subject to the matters, assumptions and limitations
set forth in the opinion, the $23 per share cash consideration to be received by
the holders of shares of Amtran common stock other than Mikelsons and his
affiliates, pursuant to the merger, was fair to such holders from a financial
point of view.


    THE FULL TEXT OF THE WRITTEN OPINION OF DRKW DATED JUNE 18, 2001, WHICH SETS
FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW
UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS ANNEX C TO THIS PROXY
STATEMENT. THE OPINION OF DRKW, DOES NOT CONSTITUTE A RECOMMENDATION AS TO HOW
YOU SHOULD VOTE WITH RESPECT TO THE MERGER, THE PLAN OF MERGER AND THE MERGER
AGREEMENT. YOU SHOULD READ THE OPINION IN ITS ENTIRETY. See 'Special
Factors -- Opinion of Financial Advisor to the Single Member Special Independent
Director Committee' (page 23).


CERTAIN PROJECTED FINANCIAL INFORMATION


    Amtran provided Mikelsons and his advisors and the single member special
independent director committee and its advisors with certain projected financial
information for Amtran for the period from 2001 through 2005. See 'Special
Factors -- Projections' (page 33).


POSITION OF THE FILING PERSONS REGARDING FAIRNESS OF THE MERGER


    For the reasons set forth in 'Special Factors -- Position of the Filing
Persons Regarding Fairness of the Merger', the filing persons believe that the
merger is fair to and in the best interests of the


                                       iv

<Page>

holders of shares of our common stock (other than the filing persons). See
'Special Factors -- Position of the Filing Persons Regarding Fairness of the
Merger' (page 31).


PLANS FOR AMTRAN AFTER THE MERGER


    Mikelsons presently intends to continue to own all the common stock of
Amtran after the merger (other than shares of our common stock which may be
issued in the future upon the exercise of stock options or the conversion of
shares of our Series B preferred stock) and for Amtran to continue to operate as
a holding company for its operating subsidiaries. See 'Special Factors -- Plans
for Amtran after the Merger' (page 36).


CERTAIN EFFECTS OF THE MERGER


    Upon consummation of the merger, each share of our common stock (other than
shares owned by us, Mikelsons or any Mikelsons Affiliate) will be canceled and
converted into the right to receive $23 in cash, without interest. Each share of
the common stock of INDUS, all of which are owned by Mikelsons, will be
converted in the merger into a share of the common stock of Amtran, as the
surviving corporation. As a result, Mikelsons will own all the common stock of
Amtran immediately after the merger. Holders of shares of our common stock
(other than Mikelsons) will cease to have an ownership interest in Amtran upon
completion of the merger. Shareholders other than Mikelsons will no longer
benefit from any increases in our value or bear the risks of any decreases in
our value. At the time the merger is completed, shares of our common stock will
be removed from quotation on the Nasdaq Stock Market and will be removed from
registration under the Securities Exchange Act of 1934, as amended. We refer to
the Securities Exchange Act of 1934, as amended, as the Exchange Act in this
proxy statement. See 'Special Factors -- Certain Effects of the Merger'
(page 36).


SOURCE AND AMOUNT OF FUNDS


    The total amount of funds we require to consummate the merger, cash out
stock options and to pay related fees and expenses is approximately $87 million.
Receipt of financing sufficient to cover these expenses is a condition to the
merger. Amtran and ATA have entered into a commitment letter dated June 18, 2001
with Citicorp USA, Inc. and Salomon Smith Barney Inc. with respect to a $175
million secured credit facility, subject to the conditions specified therein.
Bank One, NA has committed to accept a participation of $87.5 million in the
syndication of this credit facility and to act as administrative agent under
this credit facility. We expect that the structure of the secured credit
facility will include both a term loan and a revolving credit facility. We are
in the process of negotiating the definitive documentation for the secured
credit facility with the lenders. In addition, Amtran will issue a senior
unsecured note with an aggregate principal amount of approximately $2.2 million
to ILFC to repurchase a portion of their shares of Series B preferred stock
(assuming we elect to repurchase the minimum 5% of those shares required by the
ILFC Agreement). See 'Special Factors -- Source and Amount of Funds' (page 38).


INTERESTS OF CERTAIN PERSONS IN THE MERGER

    Certain of our directors and executive officers have interests in the merger
which may differ from the interests of holders of Amtran common stock generally.
In particular:


     on June 18, 2001, Mikelsons and INDUS entered into a stock subscription
     agreement, pursuant to which Mikelsons will subscribe for and purchase, and
     INDUS will issue to Mikelsons, 8,271,200 shares of the common stock,
     without par value, of INDUS, in consideration of the contribution by
     Mikelsons to INDUS of the 8,271,200 shares of our common stock owned by
     him, subject to the conditions specified therein. See 'Special
     Factors -- Interests of Certain Persons in the Merger -- Mikelsons and
     INDUS Ownership of Common Stock' (page 41).



     as of September 5, 2001, our executive officers and directors (other than
     Mikelsons) beneficially owned an aggregate of 1,300,467 shares of our
     common stock consisting of 84,762 shares of common stock (which represented
     on that date less than 1% of the


                                       v

     outstanding shares and approximately 2.6% of the outstanding shares not
     owned by Mikelsons or any Mikelsons Affiliate), presently exercisable
     options to purchase 1,214,689 shares of common stock with an average
     exercise price of $11.20 per share and 1,010 shares of our common stock
     allocated to such directors and executive officers under the ATA Employees'
     Salary Savings Plan. To our knowledge, all of our executive officers and
     directors intend to vote the 85,772 shares of our common stock which they
     have the power to direct the voting of in favor of all items presented at
     the annual meeting. See 'Special Factors -- Interests of Certain Persons in
     the Merger -- Ownership of Common Stock by Our Officers and Directors'
     (page 41).



     as of September 5, 2001, Mr. Tague beneficially owned 460,980 shares of our
     common stock (including options to purchase 450,758 shares with an average
     exercise price of $12.52), Mr. Wolff beneficially owned 350,094 shares of
     our common stock (including options to purchase 338,000 shares with an
     average exercise price of $13.48) and Mr. Hlavacek beneficially owned
     362,393 shares of our common stock (including options to purchase 309,431
     shares with an average exercise price of $13.86); Messrs. Tague, Wolff and
     Hlavacek intend to vote all shares of our common stock which they have the
     power to direct the voting of in favor of all items at the annual meeting.
     See 'Special Factors -- Interests of Certain Persons in the
     Merger -- Ownership of Common Stock by Our Officers and Directors'
     (page 41).



     the restriction period for each restricted share, whether vested or
     unvested, granted under any of our stock plans will expire immediately
     prior to the closing of the merger, unless it expired sooner under the
     terms of the stock plan. See 'Special Factors -- Interests of Certain
     Persons in the Merger -- Treatment of Restricted Stock' (page 41).



     all unvested stock options issued to our officers and certain stock options
     issued to non-officers automatically vested upon the approval of the merger
     by your board of directors. See 'Special Factors -- Interests of Certain
     Persons in the Merger -- Treatment of Stock Options' (page 42).



     your board of directors and the compensation committee of your board of
     directors have adopted resolutions providing that all stock options (other
     than those held by the 19 officers whose options will remain outstanding
     following the merger) that are outstanding immediately prior to the closing
     of the merger will be canceled in exchange for a cash payment equal to the
     excess, if any, of $23 over the exercise price of those options multiplied
     by the number of shares of our common stock covered by those options, and
     that all outstanding stock options with an exercise price in excess of $23
     per share will be canceled without any cash payment. In the aggregate, our
     employees (other than the 19 officers described in the following paragraph)
     held as of September 4, 2001 options to purchase 520,015 shares of our
     common stock with an average exercise price of $11.87 per share. See
     'Special Factors -- Interests of Certain Persons in the Merger -- Treatment
     of Stock Options' (page 42).



     we have entered into option modification agreements with 19 of our officers
     (including Messrs. Tague, Wolff and Hlavacek) providing that these officers
     will not exercise their options prior to the merger and that their stock
     options will remain outstanding following the merger. Under these
     agreements, these officers have agreed not to exercise their options except
     during certain limited exercise periods, and then only if certain
     additional conditions are satisfied. The first exercise period is scheduled
     to begin in June 2002. These officers would also have the right,
     exercisable during limited periods for five years following an option
     exercise, to sell the shares of our common stock received upon that option
     exercise to us at a price per share determined by an independent appraiser.
     In addition, we expect to increase the compensation of a portion of these
     officers following completion of the merger by an amount sufficient to
     compensate them for any decrease in overall compensation resulting from the
     merger and the rollover of their options. See 'Special Factors -- Interests
     of Certain Persons in the Merger -- Treatment of Stock Options' (page 42).


                                       vi

<Page>

     under the merger agreement, we, as the surviving corporation in the merger,
     have agreed to honor all of our obligations to indemnify our current and
     former directors and officers for acts or omissions occurring prior to the
     effective time of the merger whether pursuant to our charter, bylaws, in
     individual indemnity agreements or otherwise. In addition, we, as the
     surviving corporation in the merger, have agreed to maintain directors' and
     officers' liability insurance on behalf of those directors and officers
     that are currently covered by our existing directors' and officers'
     liability insurance policies for a period of six years. Mikelsons and INDUS
     have agreed to indemnify Messrs. Tague, Wolff and Hlavacek against certain
     liabilities under the Exchange Act arising by reason of their status as
     filing persons of the Schedule 13E-3 filed with respect to the merger. See
     'Special Factors -- Interests of Certain Persons in the
     Merger -- Indemnification of Officers and Directors' (page 42).



     ILFC has agreed to vote its shares of our Series B preferred stock in favor
     of the ILFC amendment and to modifications to the terms of the Series B
     preferred stock making it convertible into shares of our common stock
     following the merger, and we have agreed to purchase between 5% and 10%
     (with Amtran to determine the amount to be purchased) of their shares of
     Series B preferred stock at a price reflecting the merger consideration
     paid to holders of shares of our common stock. We currently expect to
     purchase 5% of the outstanding shares of Series B preferred stock. Assuming
     that we purchase 5% of its shares of Series B preferred stock and that ILFC
     converts all its remaining shares of Series B preferred stock following the
     merger, ILFC would own approximately 1,818,762 shares of our common stock.
     The ILFC amendment also modifies the redemption and termination of
     convertibility provisions to include a premium equal to the spread between
     $23 and the conversion price and increases the dividend rate on the Series
     B preferred stock upon the completion of the merger. See 'Special
     Factors -- Interests of Certain Persons in the Merger -- Proposed ILFC
     Amendment' (page 43).



     as part of our purchase and voting agreement with ILFC, we have also agreed
     to lease an additional Boeing 737-800 aircraft from ILFC beginning in 2004
     and to pay ILFC an annual fleet consulting fee of $100,000 for four years
     following completion of the merger. See 'Special Factors -- Interests of
     Certain Persons in the Merger -- Proposed ILFC Amendment' (page 43).



     under the terms of the plan of merger and the merger agreement, our current
     directors (other than William P. Rogers, Jr., who is not standing for
     re-election at the annual meeting) and officers will also be the directors
     and officers of the surviving corporation. See 'Special
     Factors -- Interests of Certain Persons in the Merger -- Interests of
     Certain Directors' (page 44).



     Robert A. Abel, the sole member of the special independent director
     committee, is a partner in Blue & Co., LLC, an accounting firm which has
     provided tax and accounting services to us, Betaco, Inc. and Mikelsons in
     2000. Blue & Co. billed Amtran $28,310 for tax and accounting services in
     2000. Mikelsons is the sole owner of Betaco. Blue & Co. billed Betaco
     $20,835 for tax and accounting services provided to Betaco and Mikelsons in
     2000. Mikelsons has advised us that he currently expects that Blue & Co.
     will continue to provide certain tax and accounting services to Amtran,
     Betaco and Mikelsons following the merger. See 'Special
     Factors -- Interests of Certain Persons in the Merger -- Interests of
     Certain Directors' (page 44).



     William P. Rogers, Jr., a director of Amtran, is a partner in Cravath,
     Swaine & Moore, which is acting as Mikelsons' legal advisor in this
     transaction. Cravath has provided legal services to us regularly and is
     expected to continue to do so. Cravath billed Amtran approximately $641,399
     in fees and expenses for legal services rendered to Amtran in 2000. See
     'Special Factors -- Interests of Certain Persons in the Merger -- Interests
     of Certain Directors' (page 44).



     at Mikelsons' request, Amtran engaged Salomon Smith Barney to act as
     financial advisor to Mikelsons and INDUS. In connection with this
     engagement, Amtran entered into an indemnity letter agreement with Salomon
     Smith Barney. See 'Special Factors -- Interests of Certain Persons in the
     Merger -- Amtran's Engagement of Salomon Smith Barney' (page 44).

CERTAIN FEDERAL INCOME TAX CONSEQUENCES


    If the merger is consummated, the exchange of shares of common stock by a
holder for the merger consideration will be a taxable transaction under the
Internal Revenue Code of 1986, as amended. The merger will not be a taxable
transaction for Amtran, INDUS or Mikelsons for United States federal income tax
purposes. The merger will be a taxable transaction for Messrs. Tague, Wolff and
Hlavacek. Because of the complexities of the tax laws, you are advised to
consult your own tax advisors concerning the applicable federal, state, local,
foreign and other tax consequences resulting from the merger. See 'Special
Factors -- Certain Federal Income Tax Consequences' (page 39).


SHAREHOLDER LITIGATION RELATING TO THE MERGER


    We, along with our directors, have been named in three putative class
actions, two filed in the state courts of Indiana and one in federal district
court in Indiana. The plaintiffs in these lawsuits allege that we and our
directors have breached and are breaching their fiduciary duties to the public
shareholders of Amtran common stock. These plaintiffs seek, among other things,
declaratory and injunctive relief. The defendants in these lawsuits have entered
into a memorandum of understanding with each of the plaintiffs, subject to
certain conditions, including court approval, providing for the settlement of
the lawsuits described above. See 'Special Factors -- Shareholder Litigation
Relating to the Merger' (page 40).


METHOD OF ACCOUNTING


    The merger will be accounted for as a purchase of INDUS by Amtran. See
'Special Factors -- Method of Accounting' (page 40).


REGULATORY AND OTHER APPROVALS


    The only U.S. federal or state regulatory requirements applicable to the
merger and the ILFC amendment are the giving of notice of the merger to the U.S.
Department of Transportation and the filing of articles of merger and articles
of amendment with the Secretary of State of Indiana. On August 7, 2001, we
provided notice of the merger to the U.S. Department of Transportation. See
'Special Factors -- Regulatory and Other Approvals' (page 40).


                              THE MERGER AGREEMENT

THE MERGER


    Under the merger agreement, INDUS will be merged with and into Amtran, with
Amtran as the surviving corporation. As a result of the merger, Mikelsons will
own all the outstanding shares of our common stock and each share of our common
stock outstanding at the time the merger is completed, other than shares held by
us and our subsidiaries, Mikelsons or any Mikelsons Affiliate, will be converted
automatically into the right to receive $23 per share in cash, without interest.
See 'The Merger Agreement -- The Merger' (page 46).


SURRENDER OF CERTIFICATES


    We, as the surviving corporation in the merger, will deposit with the paying
agent, National City Bank, an amount of cash sufficient to pay our former
shareholders $23 per share of our common stock upon valid surrenders of share
certificates. After completion of the merger, National City Bank will send to
each shareholder of record at the time of the merger a letter of transmittal and
detailed instructions specifying the procedures for surrendering share
certificates. YOU SHOULD NOT SEND YOUR SHARE CERTIFICATES TO AMTRAN. YOU SHOULD
NOT SEND SHARE CERTIFICATES TO NATIONAL CITY BANK UNTIL YOU RECEIVE A LETTER OF
TRANSMITTAL. Upon the valid surrender of a share certificate, National City Bank
will issue to the surrendering holder a check representing an amount of cash
equal to $23 per share of our common stock formerly represented by the share
certificates surrendered to National City Bank. See 'The Merger
Agreement -- Payment for Shares; Procedures for Surrender of Certificates'
(page 47).

    See 'The Merger Agreement -- Termination' (page 52).


DISSENTERS' RIGHTS


    Under Indiana law, because shares of our common stock are quoted on the
Nasdaq Stock Market, shareholders are not entitled to dissenters' rights in
connection with the merger. See 'Dissenters' Rights' (page 54).


                        RECENT MARKET PRICE INFORMATION


    Shares of our common stock are quoted on the Nasdaq Stock Market under the

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

    The following questions and answers are intended to address briefly some
commonly asked questions regarding the merger. These questions and answers may
not address all questions that may be important to you as an Amtran shareholder.
Please refer to the more detailed information contained elsewhere in this proxy
statement, the appendices to this proxy statement and the documents referred to
or incorporated by reference in this proxy statement.

Q: WHAT IS THE PROPOSED TRANSACTION?


A: J. George Mikelsons, founder, Chairman and 72% shareholder of Amtran, is
   proposing to acquire all the common stock of Amtran that he does not
   currently own through a merger between INDUS and Amtran. If the merger is
   completed, you will be entitled to receive $23 in cash, without interest, for
   each share of our common stock that you own on the date of the merger. As a
   result of the merger, Mikelsons will become the sole common shareholder of
   Amtran. As of September 5, 2001, Mikelsons owned 8,271,200 shares of our
   common stock, which represented approximately 72% of the outstanding shares
   of our common stock on that date.


Q: WHAT IS MY BOARD OF DIRECTORS' VIEW REGARDING THE MERGER?

A: Your board of directors, acting on the recommendation of a single member
   special independent director committee of your board of directors, has
   determined that the merger is fair to and in the best interests of Amtran and
   the holders of shares of our common stock (other than Mikelsons and any
   Mikelsons Affiliate). Your board of directors unanimously recommends that you
   vote for approval of the merger, the plan of merger, the merger agreement and
   the ILFC amendment.

Q: WHY ARE THE SINGLE MEMBER SPECIAL INDEPENDENT DIRECTOR COMMITTEE AND MY BOARD
   OF DIRECTORS RECOMMENDING THE MERGER, THE PLAN OF MERGER, THE MERGER
   AGREEMENT AND THE ILFC AMENDMENT?


A: The single member special independent director committee and board of
   directors believe that the merger is fair to and in the best interests of
   Amtran and the holders of shares of our common stock (other than Mikelsons
   and any Mikelsons Affiliate). The single member special independent director
   committee received an opinion from Dresdner Kleinwort Wasserstein, Inc. that,
   as of June 18, 2001, based on and subject to the limitations set forth in its
   opinion, the $23 in cash per share to be received by holders of shares of
   Amtran common stock (other than Mikelsons and any Mikelsons Affiliate) was
   fair to those holders from a financial point of view. The single member
   special independent director committee's reasons for recommending the merger
   to your board of directors and your board of directors' reasons for
   recommending approval of the merger, the plan of merger, the merger agreement
   and the ILFC amendment are contained on pages 17 through 23 of this proxy
   statement.


Q: IF THE MERGER IS COMPLETED, WHAT WILL I RECEIVE FOR MY SHARES OF AMTRAN
   COMMON STOCK?

A: You will receive $23 in cash, without interest, for each share of our common
   stock you own at the time of the merger, upon valid surrender of your share
   certificates.

Q: WHEN IS THE MERGER EXPECTED TO BE COMPLETED?

A: Assuming that ATA is able to obtain the financing to pay the merger
   consideration and the other conditions to the merger are met at that time, we
   expect to close the transaction during the second week of October 2001.

Q: FOLLOWING THE TRANSACTION, WILL AMTRAN CONTINUE AS A PUBLIC COMPANY?

A: No. After the merger takes place, Mikelsons will own all the common stock of
   Amtran. Shares of our common stock will no longer be eligible to be quoted on
   the Nasdaq Stock Market; however, Amtran will continue to make certain
   filings with the Securities and Exchange Commission as required under its
   indentures. Holders of our Series A1 preferred stock, Boeing Capital
   Corporation, and Series B preferred stock, ILFC, will continue to hold their
   interests in Amtran. In addition, Amtran and its subsidiaries will continue
   to have certain classes of debt securities that are publicly held.

                                SPECIAL FACTORS

BACKGROUND OF THE MERGER

    Amtran offered shares of its common stock to the public in 1993 at a price
of $16 per share. From time to time since its public offering, Mikelsons and
Amtran have considered possible strategic alternatives to remaining a public
company with Mikelsons as the majority shareholder.

    During 1998, Amtran engaged Salomon Smith Barney to assist Amtran in a
review of its strategic alternatives. As part of this process, a number of
members of the airline industry were contacted with respect to their interest in
a possible strategic transaction with Amtran. This process led another airline
company (the 'industry buyer') to initiate discussions beginning in December
1998 with respect to a possible acquisition of Amtran. Those discussions
continued intermittently through the first three fiscal quarters of 1999. In
April 1999, Amtran and the industry buyer entered into a confidentiality
agreement (including a 2-year standstill) and the industry buyer, together with
its financial advisors, engaged in a due diligence review of Amtran throughout
the summer of 1999. The discussions with the industry buyer involved a possible
acquisition of Amtran for stock or a mix of cash and stock. In the third quarter
of 1999, the industry buyer withdrew from discussions as a result of the decline
in airline industry conditions, as well as a decline in the financial prospects
of the industry buyer and Amtran and the trading prices of the industry buyer's
common stock.

    While the discussions with the industry buyer were taking place and after
obtaining the consent of the Amtran board of directors, Messrs. Tague, Wolff and
Hlavacek engaged a second financial advisor to identify potential financial
sponsors to participate with management in a leveraged buy-out of Amtran. As a
result of this process, Amtran senior management began preliminary discussions
with Apollo Management, L.P., a private equity fund ('Apollo'), in the spring of
1999. On May 28, 1999, Amtran entered into a confidentiality agreement
(including a 2-year standstill) with Apollo. During the second and third
quarters of 1999, Apollo made several indicative proposals, each of which was
subject to numerous conditions, for leveraged recapitalization transactions
involving Amtran. In the fall of 1999, discussions between Amtran and Apollo
ended.

    After discussions with Apollo commenced, the Amtran board of directors
formed a single member special independent director committee (composed of
Robert A. Abel) to consider possible strategic alternatives available to Amtran,
including possible transactions with the industry buyer and Apollo.

    In February 2000, discussions with Apollo restarted when a representative of
Apollo contacted Mr. Tague. Thereafter, members of Amtran senior management
worked with Apollo to prepare a revised leveraged recapitalization proposal. In
March 2000, Apollo submitted an indicative proposal for a leveraged
recapitalization in which all holders of shares of Amtran common stock would
have received $25 per share in cash for 96% of their shares and would retain 4%
of their shares of common stock as a continuing interest in Amtran. This
indicative proposal was subject to numerous substantive conditions, including
satisfactory completion of a due diligence review of Amtran's business. Over the
next several months, Amtran senior management, representatives of Salomon Smith
Barney and Cravath, Swaine & Moore engaged in extensive discussions with
representatives of Apollo regarding the terms and structure of this proposal.

    In response to the proposal from Apollo, at the direction of Mikelsons, a
representative of Salomon Smith Barney contacted several other airlines
regarding their possible interest in a transaction with Amtran. Discussions with
the industry buyer were reinitiated during this period but were terminated
shortly thereafter. On May 27, 2000, Mikelsons discussed a possible transaction
with Amtran with executives of another airline. None of these inquiries resulted
in proposals.

    On May 30, 2000, Amtran entered into an exclusivity agreement with Apollo
providing for a one-month exclusivity period, subject to extension by the
parties. During the exclusivity period, Apollo engaged in extensive due
diligence on Amtran and met regularly with members of Amtran senior management.
In July 2000, representatives of Apollo and Amtran senior management

                                       6

<Page>
presented the March 2000 proposal to the credit rating agencies. In response to
concerns raised by the rating agencies, Apollo made a revised indicative
proposal, subject to a number of substantive conditions, in which all holders of
shares of Amtran common stock would have received $21 per share in cash and $3
in principal amount of subordinated notes for 96% of their shares of Amtran
common stock and would have retained 4% of their shares of Amtran common stock.
After negotiations regarding this proposal, Apollo further revised its
indicative proposal to $21 per share in cash and preferred stock with a
liquidation amount of $3 per share for 96% of the outstanding shares of Amtran
common stock. After considering this revised proposal from Apollo, in September
2000, Mikelsons informed Apollo that he was not interested in participating in
the proposed recapitalization transaction. Following this decision, Amtran and
that single member special independent director committee ended discussions with
Apollo.

    After the negotiations with Apollo ended, Amtran increased market
repurchases of shares of Amtran common stock. Beginning in late December 2000,
Messrs. Mikelsons and Tague discussed the possibility of a transaction in which
Amtran would be taken private. On January 8, 2001, Mr. Tague contacted a
representative of Salomon Smith Barney to request a meeting to discuss a
possible transaction to take Amtran private. On January 12, 2001, Messrs.
Mikelsons, Tague and Wolff met with representatives of Salomon Smith Barney and
Citicorp USA, Inc. to discuss whether such a transaction would be feasible given
industry conditions. During the several weeks following this meeting, Messrs.
Mikelsons, Tague and Wolff communicated with representatives of Salomon Smith
Barney and Citicorp regarding the possible structure and financing of this type
of transaction. Due to the possibility of a going-private transaction, Amtran
senior management suspended stock repurchases on January 8, 2001.


    On January 25, 2001, William P. Rogers, Jr., a partner at Cravath, and a
director of Amtran, was contacted by senior officers of Amtran regarding a
possible going-private transaction. Representatives of Salomon Smith Barney and
Cravath (including Mr. Rogers) also discussed with Messrs. Tague and Wolff the
possible structures for and the timing of such a transaction. On January 26,
2001, Mr. Rogers contacted Benjamin F. Stapleton of Sullivan & Cromwell ('S&C'),
who had represented the previously formed single member special independent
director committee, to inform him that another special independent director
committee might be needed.


    During the following month, Messrs. Mikelsons, Tague and Wolff participated
in a number of conference calls and meetings with Mr. Rogers and other attorneys
at Cravath regarding possible structures for a transaction, the limitations on
restricted payments contained in Amtran's indentures and the impact of the
proposed transaction on the outstanding shares of Series B preferred stock,
which are convertible into shares of Amtran common stock, held by ILFC. Messrs.
Tague and Wolff also discussed with Mr. Rogers and other attorneys at Cravath
the effect of the proposed transaction on Amtran's stock options and discussed
possible structures in which stock options held by Amtran's senior officers
could remain outstanding instead of being cashed out. During the same period,
members of Amtran's strategic planning department discussed with representatives
of Salomon Smith Barney and Citicorp a draft of a 5-year business plan that
Amtran's senior officers had produced and the financial model underlying that
plan. During February and early March, 2001, Messrs. Tague and Wolff began
negotiations (via telephone conference and in person) with Salomon Smith Barney
and Citicorp regarding the financing terms for a possible transaction.

    In early February 2001, Mr. Wolff contacted another financial institution
(the 'alternative financial advisor') about providing financing and advisory
services with respect to the possible transaction. On several occasions during
March 2001, the alternative financial advisor discussed the financing and
structure of the possible transaction with representatives of Cravath (including
Mr. Rogers) and Amtran senior management. Representatives of the alternative
financial advisor also discussed possible financing terms with Mr. Wolff and
representatives of Cravath (including Mr. Rogers) throughout March and April
2001. Mikelsons also continued to pursue negotiations with representatives of
Salomon Smith Barney and Citicorp regarding the terms and conditions of a
commitment letter.

    Beginning in the last week of March 2001, a representative of Apollo placed
telephone calls to Messrs. Mikelsons and Tague and representatives of Salomon
Smith Barney. On April 2, 2001, a

                                       7

<Page>
representative of Apollo sent a letter to Mikelsons, with a copy to Salomon
Smith Barney, expressing continued interest in a transaction involving Amtran.
This letter was discussed at a meeting on April 3, 2001, among Messrs. Tague and
Wolff and representatives of Salomon Smith Barney and Cravath (including
Mr. Rogers). Negotiations over the terms of Salomon Smith Barney and Citicorp's
commitment letter also continued throughout this week.

    On April 5, 2001, at the request of Mikelsons, representatives of Salomon
Smith Barney contacted a representative of Apollo to respond to the April 2
letter. In this conversation, the representative of Apollo stated that it
remained interested in a transaction with Amtran but was prevented from making a
proposal by the standstill provision contained in the confidentiality agreement
which it had previously entered into with Amtran. The representative of Apollo
stated that he had heard rumors that Mikelsons was considering a possible
transaction to take Amtran private and that Apollo would be interested in
participating as a minority partner in such a transaction.

    On April 6, 2001, following telephone conversations among Messrs. Mikelsons,
Tague and Rogers and representatives of Salomon Smith Barney, Mr. Tague and
representatives of Salomon Smith Barney then placed a telephone call to
representatives of Apollo. At the request of Mikelsons, a representative of
Salomon Smith Barney informed the representatives of Apollo that Mikelsons was
not interested in selling his stake in Amtran to Apollo or participating in a
transaction with Apollo, but that Amtran would waive the standstill provision to
permit Apollo to communicate a proposal to the Amtran board of directors if it
wished to do so. In response, a representative of Apollo indicated that it would
be interested in making such a proposal and requested updated non-public
information with respect to Amtran. Based on their understanding of Mikelsons'
lack of interest in selling his shares of Amtran common stock, members of Amtran
management rejected this request. On April 11, 2001, Apollo sent a letter to
Messrs. Mikelsons and Tague and a representative of Salomon Smith Barney
proposing to purchase all the outstanding shares of Amtran common stock for $20
per share in cash, subject to satisfactory completion of additional due
diligence; the letter stated that Apollo might be prepared to offer a price in
excess of $20 per share based on the results of a due diligence update. Apollo
also indicated that it would be interested in participating, in a minority role,
in a transaction in which Amtran was taken private.

    In early April 2001, Mr. Rogers discussed with Mr. Abel the possibility of
Mikelsons proposing to take Amtran private and the need to constitute another
special independent director committee to consider any proposal that Mikelsons
might make. Mr. Abel indicated that he would be willing to serve in that
capacity again. Mr. Abel subsequently retained S&C to act as independent legal
advisor to the single member special independent director committee. Messrs.
Abel and Stapleton discussed the process of retaining a financial advisor for
the single member special independent director committee and several investment
banks were contacted. By unanimous written consent dated April 18, 2001, the
Amtran board of directors formed a single member special independent director
committee composed of Mr. Abel.

    During the week beginning April 16, 2001, Mr. Abel, together with
representatives of S&C, received presentations from three investment banks being
considered to represent the single member special independent director
committee, including DrKW.

    During that same week, Messrs. Tague and Wolff, with the assistance of
representatives of Salomon Smith Barney and Cravath (including Mr. Rogers),
prepared a draft term sheet to be presented to ILFC regarding the proposed
modification of the terms of their shares of Amtran Series B preferred stock.
Mr. Wolff sent this term sheet to ILFC, following the execution of a
confidentiality agreement by ILFC on April 24, 2001. This draft term sheet
proposed changes to the conversion and antidilution provisions of the Series B
preferred stock to provide for periodic appraisals to reflect the absence of a
public market for shares of Amtran's common stock upon completion of a
transaction in which Amtran was taken private and that ILFC agrees not to
convert its shares of Series B preferred stock prior to completion of the
proposed transaction.

    In mid-April 2001, Messrs. Tague and Wolff met with representatives of Bank
One, NA to discuss Bank One NA's interest in participating in the financing of a
possible transaction.

    On April 24, 2001, a representative of Apollo placed a telephone call to
Mr. Tague. After discussing this telephone call with Mr. Rogers, Mr. Tague
returned the telephone call to the representative of Apollo, and informed the
representative of Apollo that Mikelsons was not interested in participating in a
transaction with Apollo.

    Between April 24, 2001 and May 3, 2001, Messrs. Tague and Wolff, together
with representatives of Cravath, further negotiated the draft commitment letter
from Salomon Smith Barney and Citicorp and the draft commitment letter from the
alternative financial advisor commitment letter. On May 3, 2001, Salomon Smith
Barney and Citicorp delivered a final form of commitment letter to Amtran.
Discussions with the alternative financial advisor ceased at this time.

    On April 26, 2001, a representative of ILFC called Mr. Wolff regarding
ILFC's view that additional modifications to the terms of the Series B preferred
stock would be appropriate in connection with a transaction in which Amtran
would be taken private. The additional modifications suggested by ILFC included
an increase in the dividend rate on the Series B preferred stock, an increase in
the redemption premium to reflect the going-private transaction, the repurchase
of a portion of ILFC's shares of Series B preferred stock, increased voting and
governance rights, and commitments by Amtran to enter into operating lease
agreements with ILFC with respect to additional aircraft. A representative of
ILFC delivered a term sheet containing those proposals to Amtran on April 30.
Messrs. Tague and Wolff reviewed ILFC's term sheet with representatives of
Salomon Smith Barney and Cravath (including Mr. Rogers) on May 2, 2001.

    On April 27, 2001, Mr. Rogers called Mr. Stapleton to inform him that an
agreement in principle had been reached with Salomon Smith Barney and Citicorp
with respect to the financing of a possible transaction and to discuss the
possible timing of a proposal by Mikelsons.

    On May 3, 2001, Messrs. Mikelsons, Tague and Wolff met with representatives
of William M. Mercer and Cravath (including Mr. Rogers) to provide advice to
Mikelsons on compensation issues, including the proposal for senior officers to
roll their options forward.

    Later on May 3, Messrs. Mikelsons, Tague and Wolff met with representatives
of Salomon Smith Barney, Citicorp and Cravath (including Mr. Rogers) to review
ILFC's proposed terms and to discuss the overall timing of a possible
transaction. On May 4, 2001, following these discussions, Mr. Wolff sent revised
term sheets to representatives of ILFC. These revised term sheets contained two
alternative responses to ILFC's proposed modifications to the terms of the
Series B preferred stock. The first alternative contemplated that the Series B
preferred stock would continue to be convertible into shares of Amtran common
stock but the redemption premiums would be increased to reflect the transaction
price. The second response modified the terms of the Series B preferred stock to
eliminate the conversion feature and provided that the dividend rate on shares
of Series B preferred stock be increased to a rate comparable to the rate on the
Series A1 preferred stock. On May 7, 2001, Messrs. Tague and Wolff, together
with a representative of Salomon Smith Barney, met with representatives of ILFC
to negotiate the terms of the modifications to the Series B preferred stock. On
May 9, 2001, representatives of Cravath sent draft agreements to representatives
of ILFC.

    On May 8, 2001, the single member special independent director committee
decided to retain DrKW as its financial advisor based on DrKW's experience in
representing special committees, the fact that DrKW had not worked with Amtran
in the past and DrKW's fee structure.

    On May 11, 2001, Mr. Wolff and Charles Fuller, Director of Strategic
Planning of Amtran, met with representatives of General Electric Capital
Aviation Services, one of Amtran's main sources of aircraft financing, and
disclosed that Mikelsons was considering taking Amtran private. At this meeting,
General Electric Capital Aviation Services entered into a confidentiality
agreement with respect to this information. On May 14, 2001, Messrs. Wolff and
Fuller held a similar meeting over dinner with representatives of Boeing Capital
Corporation. At this meeting, Boeing Capital Corporation entered into a
confidentiality agreement with respect to this information.

    In addition, on May 14, representatives of S&C sent Mr. Rogers a due
diligence request prepared by DrKW.

                                       9

<Page>
    On May 15, 2001, following consultation with his financial and legal
advisors, Mikelsons determined to submit a proposal to take Amtran private at
$21 per share in cash.

    On May 15, 2001, representatives of Cravath and counsel for ILFC finalized
the agreements modifying the terms of the Series B preferred stock. These
agreements were executed and delivered by the parties on the afternoon of
May 16, 2001.

    Following the close of the stock markets on May 16, copies of Mikelsons'
letter proposing to take Amtran private for $21 per share in cash and the
Salomon Smith Barney and Citicorp commitment letter were sent to the members of
the Amtran board of directors and S&C. Later that afternoon, the Amtran board of
directors met telephonically to review Mikelsons' proposal and related matters.
Among the matters considered at this meeting was a request by Mikelsons that
Amtran enter into an engagement letter with Salomon Smith Barney on his behalf.

    After discussing these matters, the members of the Amtran board of
directors, other than Messrs. Mikelsons and Rogers, who each abstained, voted to
refer Mikelsons' proposal and related matters to the single member special
independent director committee for consideration and to authorize Amtran to
enter into an engagement letter with Salomon Smith Barney. That evening Amtran
issued a press release announcing receipt of Mikelsons' proposal and that the
Amtran board of directors had referred that proposal to the single member
special independent director committee. Mr. Tague also executed the engagement
letter with Salomon Smith Barney on behalf of Amtran that evening.

    On May 17, 2001, Messrs. Tague and Wolff and representatives of Salomon
Smith Barney and Cravath (including Mr. Rogers) had a conference call with
representatives of S&C and DrKW regarding the process that the single member
special independent director committee was planning to undertake (including due
diligence to be conducted by DrKW and S&C). Representatives of Cravath also sent
DrKW due diligence materials provided to Cravath by Amtran. These due diligence
materials were supplemented by additional materials on May 18 (including the
5-year plans prepared by Amtran management dated April 19, 2001 and May 16,
2001).

    Also, on May 17, Amtran and the seven members of its board of directors were
named as defendants in two putative class action lawsuits filed in the Marion
County Court in Indianapolis. Amtran was served with copies of these complaints
by certified mail on May 21, 2001.

    On May 21, 2001, representatives of S&C visited a data room at the offices
of Cravath containing due diligence materials provided by Amtran and were
provided with copies of the data room materials which they requested.

    On May 22, 2001, representatives of Cravath sent a draft form of merger
agreement to representatives of S&C.

    On May 23, 2001, DrKW provided Mr. Rogers with a list of topics which the
single member special independent director committee and DrKW would be
interested in discussing with Mikelsons. The topics covered included Mikelsons'
reasons for taking Amtran private, Mikelsons' basis for concluding his $21 per
share offer was fair, Mikelsons' intentions with respect to a sale of his shares
following the proposed transaction, prior discussions involving Apollo and the
industry buyer and whether other investors would be participating with Mikelsons
in the transaction. In the morning of May 24, 2001, representatives of Cravath
(including Mr. Rogers) discussed with Mikelsons the questions posed by DrKW.
Also present on this telephone call were Messrs. Tague and Wolff and
representatives of Salomon Smith Barney.

    In the evening of May 24, Messrs. Tague, Wolff, Rogers and Abel attended a
dinner meeting with representatives of DrKW, S&C and Salomon Smith Barney in
Chicago, Illinois. At dinner, Messrs. Tague and Wolff discussed recent airline
industry trends, Amtran's business and prospects and reviewed the specific
business segments in which Amtran operates (namely, scheduled service,
commercial charter and military charter). During that discussion, Messrs. Tague
and Wolff expressed the view that in light of an industry-wide deterioration in
financial performance and Amtran's year-to-date performance, Amtran's business
prospects for the remainder of 2001 would be worse than they had projected
originally.

                                       10

    In the morning of May 25, the meeting reconvened at Salomon Smith Barney's
Chicago offices. During these meetings, Messrs. Tague and Wolff reviewed at
length the 5-year plans prepared by Amtran management. In particular, these
discussions covered the risks inherent in Amtran's shift away from commercial
charter service and toward predominantly scheduled service, Amtran's transition
to a new fleet type, one of the youngest fleets in the airline industry, from an
older fleet type in a short period of time (including the risks posed by that
transition and the temporary reduction in maintenance costs resulting from that
transition) and the risks posed by the labor situation in the airline industry
generally and high fuel costs. At this meeting, representatives of DrKW
requested that Amtran management include additional cases in its 5-year plan
reflecting various scenarios, including, a scenario in which Amtran's fuel costs
remained constant throughout the 5-year period, a scenario in which rival
airlines increased direct competition on Amtran's routes in an effort to reduce
Amtran's market share on those routes, a scenario in which there was a recession
during the 5-year period and a scenario reflecting all of these adjustments.
DrKW also requested that Amtran management prepare a case which adjusted the
maintenance expenses throughout the period covered by the projections to reflect
the fact that maintenance costs will be abnormally low during the period from
2002 to 2005 due to the rapid transition to a younger fleet. At this meeting,
Mr. Abel and representatives of DrKW and S&C asked questions of Amtran
management.

    Later in the morning, Mikelsons joined the meeting. DrKW asked Mikelsons
questions covering the topics outlined in the questions provided to Mr. Rogers
on May 23. In response to these questions, Mikelsons discussed the fact that
taking Amtran private at the present time would permit management to focus on
the implementation of long-term strategic goals without having to undergo the
scrutiny of the public equity markets, which are unlikely to reflect the
potential benefits of these initiatives at any time in the near future.
Mikelsons also stated that he believed $21 per share was a fair price given,
among other things, the difference between the offer price and the recent market
price of shares of Amtran common stock. During this discussion, Mikelsons made
clear that he does not intend to sell his shares of Amtran common stock either
in connection with the proposed transaction or following the transaction.
Mikelsons, together with Messrs. Tague and Wolff, reviewed for the
representatives of DrKW the history of the prior discussions involving Apollo
and the industry buyer. Mikelsons also confirmed to the representatives of DrKW
and Mr. Abel that there were no other investors that would be participating with
Mikelsons in the transaction. At the request of DrKW, Mikelsons also gave a
brief overview of the history of the airline since its founding in 1973. There
was also further discussion between Mr. Rogers and representatives of DrKW and
S&C regarding the structure of the transaction. At the conclusion of the
meeting, the group also discussed the April 11, 2001 proposal received from
Apollo and Mr. Mikelsons' statements that he was not interested in selling his
shares of common stock. The advisors to the single member special independent
director committee then advised Mr. Mikelsons and the members of Amtran
management that they wished to contact Apollo to discuss the proposal and asked
whether Mikelsons or Amtran's management would object to the advisors doing so.
Mikelsons and Amtran's management indicated that they had no objection.

    After the Chicago meetings concluded, Amtran management arranged to have
delivered to DrKW additional due diligence materials regarding matters discussed
in those meetings and for DrKW to visit Amtran's Chicago and Indianapolis
operations.

    On May 29, 2001, representatives of DrKW and S&C contacted a representative
of Apollo to discuss the April 11, 2001 proposal. The representative of Apollo
confirmed that it was willing to acquire all of the outstanding shares of Amtran
common stock for $20 per share and that, if it was provided with updated
non-public information regarding Amtran, it might be prepared to offer more than
$20 per share. The representatives of DrKW and S&C then informed Apollo that
they understood Mikelsons was not interested in selling his interest in Amtran
and that they had no authority to offer Amtran for sale. The representative of
Apollo informed the single member special independent director committee's
advisors that it could be interested in acquiring the minority shareholders'
interest in Amtran at the same price, using the proposed financing that
Mikelsons had arranged, and then participating in a minority role with what
Apollo characterized

                                       11

<Page>
as 'customary minority protections'. In response to a request by representatives
of DrKW for more information regarding what Apollo meant by 'customary minority
protections', a representative of Apollo stated that they would be 'extensive'
and 'complicated'. No further detail was provided. The representatives of DrKW
and S&C then inquired whether Apollo would be interested in simply acquiring the
minority interest and holding it without any special minority protections. The
representative of Apollo indicated that it would not be interested in a minority
position in Amtran without appropriate minority rights and power sharing
arrangements.

    Once this telephone call was completed, representatives of DrKW and S&C
contacted representatives of Salomon Smith Barney to discuss Apollo's continuing
interest in Amtran. During this conversation, a representative of DrKW indicated
that DrKW's preliminary valuation work and the prior proposals from Apollo were
leading DrKW to conclude that an appropriate price was above $21 per share in
cash. That afternoon, representatives of Salomon Smith Barney and Mr. Rogers had
several conversations with Messrs. Tague and Wolff regarding this conversation.
Mr. Wolff also spoke with representatives of Salomon Smith Barney and Cravath
regarding an error which was found in Amtran's model used to prepare its
May 16, 2001 5-year plan.

    Also, on May 29, 2001, the annual meeting of Amtran shareholders was
adjourned.

    On May 30, 2001, representatives of DrKW met with additional members of
Amtran management, including Messrs. Hlavacek and McKnight, and performed due
diligence on additional aspects of Amtran's operations in Chicago and
Indianapolis with representatives of Salomon Smith Barney and Cravath present.

    Later on May 30, Messrs. Tague and Wolff met with representatives of DrKW,
Salomon Smith Barney and Cravath and began discussing the 5-year plans produced
by Amtran management, the error in the model which had been identified the day
before and the alternative scenarios that DrKW requested at the May 25 meeting.
That afternoon, a representative of DrKW repeated to Messrs. Tague and Wolff and
representatives of Salomon Smith Barney and Cravath that DrKW's view was that an
appropriate price for Amtran was above $21 per share. On May 31, 2001, Amtran
provided representatives of DrKW with copies of the corrected 5-year base plan
and supplemental 5-year plans covering the alternative scenarios requested to be
prepared by DrKW.

    Amtran and the seven members of its board of directors were named as
defendants in a third putative class action lawsuit, which was filed in federal
district court in Indianapolis on May 30, 2001. Amtran and all the members of
the board of directors were served with copies of this complaint by certified
mail at Amtran's offices on June 6, 2001.

    On May 31, 2001, representatives of S&C sent a mark-up of the draft merger
agreement to representatives of Cravath. In the afternoon of June 1, 2001,
representatives of Cravath (including Mr. Rogers) and S&C negotiated the
non-financial terms of the draft merger agreement.

    In the morning of June 1, 2001, representatives of DrKW conducted additional
due diligence via conference call with additional members of Amtran management.
Representatives of S&C, Salomon Smith Barney and Cravath also listened to this
conference call.

    On June 1 and June 2, 2001, at the direction of Mikelsons, representatives
of Salomon Smith Barney had several conversations with representatives of DrKW
regarding Mikelsons' offer, the need for adjustments to the discounted cash flow
analysis to reflect the temporary decline in maintenance costs resulting from
the transition to a new fleet, the prior proposals received by Amtran from
Apollo and the decline in Amtran's financial prospects since those proposals
were made, the use of comparable company and precedent transaction analyses, the
fact that Amtran's indentures contain limitations on restricted payments which
would limit the amount that could be paid as merger consideration while still
allowing Amtran to satisfy its obligations to pay dividends on its shares of
preferred stock, the accuracy of Amtran management's prior projections and
budgets and the decline in Amtran's cash flow between 2004 and 2005 contained in
the 5-year plan. Representatives of Salomon Smith Barney and DrKW continued to
discuss these topics on an ongoing basis over the following two-week period.

    During the period from May 16 to June 5, 2001, Mr. Abel had frequent
telephonic conversations with representatives of DrKW, S&C and Sommer & Barnard,
Indiana counsel to the

                                       12

<Page>
single member special independent director committee, to discuss the status of
the financial and legal due diligence process.


    In the morning of June 5, 2001, the single member special independent
director committee met at the New York offices of S&C with representatives of
S&C, DrKW and Sommer & Barnard. A representative of Sommer & Barnard reviewed
the single member special independent director committee's legal duties under
Indiana law. Representatives of DrKW reviewed with the single member special
independent director committee the results of their financial and business due
diligence and analysis of Amtran. DrKW later confirmed and updated these
preliminary results and analysis in DrKW's final report, dated June 18, 2001, to
the single member special independent director committee. The final report,
which was substantially similar to DrKW's June 5, 2001 preliminary report, is
described later in this proxy statement under the caption ' -- Opinion of
Financial Adviser to the Single Member Special Independent Director Committee.'
Copies of both reports have been filed as Exhibits to the Schedule 13E-3 filed
with the SEC by Amtran and the filing persons. At the conclusion of the meeting,
the single member special independent director committee decided to continue to
negotiate in order to attain a price per share above the $21 per share initial
offer and that DrKW should advise Salomon Smith Barney that Mr. Mikelsons would
need to offer $26 per share in order for the single member special independent
director committee to recommend his proposal.


    In the morning of June 5, 2001, Cravath provided S&C with a revised draft of
the merger agreement, reflecting certain of the changes requested by S&C in the
negotiation on June 1. In the afternoon of June 5, representatives of Salomon
Smith Barney, Cravath (including Mr. Rogers), DrKW, S&C and Sommer & Barnard
met. At this meeting, representatives of DrKW made a presentation regarding
their preliminary valuation work on Amtran based on the 5-year plan and
alternative scenarios prepared by Amtran management. As part of this
presentation, representatives of DrKW questioned the fact that the 5-year plan
prepared by Amtran showed a decline in cash flow between 2004 and 2005. There
was also discussion of DrKW's conversations with Apollo and the relevance of
Apollo's proposals in 2000 to a determination of the value of Amtran in June
2001.

    In response to this presentation, representatives of Salomon Smith Barney
questioned certain portions of DrKW's financial analysis, including, in
particular, DrKW's reliance on its discounted cash flow analysis and DrKW's
stated belief that it was unable to draw any conclusions from its comparable
company analysis. After listening to these responses, a representative of DrKW
stated that he believed that the single member special independent director
committee's preliminary view was that it would likely be able to recommend a
price of $26 per share. However, he invited Salomon Smith Barney to discuss
further the financial analysis presented at the meeting and to make available
additional information regarding Amtran to the extent useful in refining the
financial analysis. The relevance and valuation of the proposals by Apollo was
also discussed at this meeting. The discussion of the valuation of Apollo's
proposals focused on the need to value each component of these proposals by
taking into account the relevant market conditions that existed at the time the
proposal was made, thereby resulting in the market value of the non-cash
components of each proposal being discounted relative to the face value of such
non-cash components.

    Beginning in the morning of June 6, 2001 and continuing through June 8,
2001, representatives of DrKW and Salomon Smith Barney had a number of telephone
calls regarding the valuation work done by DrKW through that time. The topics
discussed included DrKW's valuation analysis based on comparable companies, the
appropriate methodology for determining the enterprise value of Amtran, the
reasons underlying the decline in cash flow between 2004 and 2005 in Amtran's
5-year plan, the relative weightings of the 5-year plan scenarios and the
variances between Amtran's forecasts and actual historical results.

    On June 11, 2001, representatives of Salomon Smith Barney and Cravath had a
conference call with Mr. Wolff regarding the variances over the last three years
in Amtran's forcasts versus its actual historical results. Thereafter,
representatives of Salomon Smith Barney provided representatives of DrKW with a
comparison of Amtran management's budgets (prepared two

                                       13

<Page>
months prior to the beginning of each year) with actual performance in 1998,
1999 and 2000 based on the information provided to DrKW by Amtran's management.
Representatives of Salomon Smith Barney thereafter had several telephone
conversations with representatives of DrKW regarding DrKW's discounted cash flow
analysis of Amtran.

    Also on June 11, representatives of S&C and Cravath had additional
negotiations on the non-financial terms of the draft merger agreement. A revised
draft of the merger agreement was distributed to representatives of S&C on
June 12.

    In the morning of June 12, 2001, representatives of DrKW and S&C contacted
representatives of Cravath to indicate that the single member special
independent director committee had determined that it would not recommend
Mikelsons' offer of $21 per share. They also indicated that the single member
special independent director committee's views on valuation had not changed
since the June 5 presentation. Following receipt of this determination, Messrs.
Mikelsons, Tague and Wolff participated in a conference call with
representatives of Salomon Smith Barney and Cravath (including Mr. Rogers).
Mikelsons indicated that he was not prepared to increase his offer at that time
and expressed his view that industry conditions had deteriorated since he made
his proposal on May 16, 2001, and were continuing to deteriorate. Also, on
June 12, representatives of Salomon Smith Barney provided to representatives of
DrKW a comparison between Amtran's forecasts in July 2000 and the current 5-year
plan.

    In the morning of June 13, 2001, at Mikelsons' request, representatives of
Salomon Smith Barney sent information regarding the recent performance of Amtran
and the airline industry generally to representatives of DrKW and, later that
day, discussed the information via a conference call with representatives of
DrKW, Messrs. Tague and Wolff and representatives of Cravath and S&C. During
this conference call, a representative of DrKW reiterated his view that the
single member special independent director committee would not conclude an offer
of $21 per share was fair. There was also discussion of the limitations on
restricted payments contained in Amtran's indentures. Messrs. Wolff and Tague
undertook to provide to representatives of Salomon Smith Barney and DrKW with an
updated calculation of those limitations by the end of that day.

    After this conference call, there was, at the request of a representative of
DrKW, a telephone call between representatives of DrKW and Salomon Smith Barney
on which a representative of DrKW indicated that he believed, based on the
updated valuation work done since the June 5 meeting to account for changes in
the number of outstanding Amtran shares and options, that the single member
special independent director committee might be willing to consider an offer of
$24 per share in cash. During this telephone call, a representative of Salomon
Smith Barney indicated that he believed Mikelsons might be willing to increase
his offer by $1 to $2 per share.

    In the late afternoon of June 13, Amtran provided a calculation of amounts
available under the restricted payments limitation to representatives of Salomon
Smith Barney and Cravath. On June 13, representatives of S&C and Cravath also
held further negotiations on the non-financial terms of the draft merger
agreement.

    During the day on June 14, 2001, Amtran provided calculations of the
restricted payment limitation to Mikelsons and representatives of Salomon Smith
Barney and Cravath. In the afternoon of June 14, Messrs. Mikelsons, Tague and
Wolff had a telephone conference call with representatives of Salomon Smith
Barney and Cravath (including Mr. Rogers) to discuss the calculations prepared
by Amtran. At the conclusion of this telephone call, representatives of Salomon
Smith Barney were instructed by Mikelsons to attempt to come to an understanding
with DrKW on price. Following this discussion, the calculations of the
restricted payments limitation were provided to representatives of DrKW and
representatives of Salomon Smith Barney contacted representatives of DrKW to
discuss the calculations.

    Also on June 14, representatives of Cravath continued negotiations with
representatives of S&C with respect to the non-financial terms of the draft
merger agreement and distributed a further revised draft of the merger agreement
to representatives of S&C.

    In the morning of June 15, 2001, representatives of Salomon Smith Barney and
DrKW had a number of telephone conversations to review Amtran's calculation of
the restricted payments

                                       14

<Page>
limitation. These representatives also discussed the proper valuation
methodology for the September 2000 proposal by Apollo, focusing in particular on
the valuation of the non-cash components of the September 2000 proposal and the
likelihood that Apollo would propose to include $21 per share in cash in a
similar proposal in light of the decline in Amtran's projections since
September 2000.

    In the early afternoon of June 15, 2001, at Mikelsons' request,
representatives of Salomon Smith Barney contacted representatives of DrKW by
telephone to indicate that Mikelsons was willing to offer a price of $22.50 per
share in cash. In the afternoon of June 15, 2001, the single member special
independent director committee held a telephonic meeting with representatives of
S&C and DrKW, at which time DrKW advised the single member special independent
director committee that Mikelsons had raised his offer price from $21.00 to
$22.50. DrKW discussed this new offer with the single member special independent
director committee in light of Amtran's restricted payments calculation provided
to the single member special independent director committee on June 15, which
calculation indicated a smaller amount of availability under the restricted
payments limitation than the calculations prepared by DrKW. These calculations
indicated that Amtran might risk being unable to make restricted payments under
its indentures if the offer price were at or above $23.00 per share. The single
member special independent director committee instructed DrKW to counter
Mikelsons' revised proposal with a proposal of $23.50 per share. Following the
single member special independent director committee meeting, representatives of
DrKW contacted representatives of Salomon Smith Barney to respond to Mikelsons'
proposal of $22.50 per share with a proposed price of $23.50 per share in cash.
After speaking with Mikelsons, representatives of Salomon Smith Barney contacted
representatives of DrKW to indicate that Mikelsons had directed them to indicate
that he was willing to offer $23 per share in cash. Upon receipt of this offer,
the representatives of DrKW indicated that they thought, subject to completion
of negotiations on the draft merger agreement, that they would be prepared to
favorably recommend that offer to the single member special independent director
committee. At the time, Mikelsons was aware that the plaintiffs had stated that
they would be willing to settle their claims, subject to court approval, if the
consideration paid in the proposed transaction was at least $23 per share.

    In the evening of June 15, representatives of Cravath and S&C negotiated the
remaining open issues on the draft merger agreement. In the early morning of
June 16, representatives of Cravath distributed a substantially final draft of
the merger agreement to representatives of S&C. There were two further
discussions between representatives of S&C and Cravath on June 16 and June 17
regarding additional minor changes to the agreed form of merger agreement.

    Throughout the period from June 11 through the evening of June 17,
representatives of Cravath negotiated with the attorneys representing the
plaintiffs in the two lawsuits brought in Indiana state court challenging the
proposed transaction about the terms on which those lawsuits could be settled.
In the morning of June 18, 2001, a memorandum of understanding regarding the
settlement of these lawsuits, and the lawsuit brought in federal court, with the
attorneys for the plaintiffs was finalized. Under the memorandum of
understanding, the parties agreed, among other things, to attempt, in good
faith, to agree upon and execute as soon as practicable an appropriate
stipulation of settlement, dismissing on the merits and with prejudice all
claims asserted in the complaints filed in the state court actions, and to
obtain final state court approval of the settlement and the release and
dismissal of the state court actions with prejudice and to voluntarily dismiss
the federal court action. The settlement is subject to confirmatory discovery.
In the memorandum of understanding, the defendants acknowledged that the
existence of these lawsuits was a factor in Mikelsons' decision to increase the
consideration per share he would pay and Mikelsons agreed that he took into
account the desirability of satisfactorily addressing the claims asserted in
these lawsuits in agreeing to increase the consideration he would pay.
Additionally, Amtran agreed to pay an aggregate of $285,000 in attorneys' fees.

    Following the closing of the stock markets on June 18, 2001, the single
member special independent director committee met. On the afternoon of June 18,
2001, the single member special independent director committee held a telephonic
meeting with representatives of S&C,

                                       15

<Page>
representatives of DrKW and a representative of Sommer & Barnard to discuss the
$23 per share proposal by Mikelsons. After reviewing DrKW's financial analysis,
DrKW advised the single member special independent director committee that
subject to certain assumptions and limitations which were described to the
single member special independent director committee, in its opinion, the $23
per share cash consideration to be received by the holders of shares of Amtran's
common stock (other than Mikelsons and his affiliates) was fair to such
shareholders from a financial point of view. S&C then reviewed the terms of the
proposed merger agreement with the single member special independent director
committee. The single member special independent director committee then
resolved to recommend the revised proposal to the board of directors of Amtran.

    Upon the conclusion of the single member special independent director
committee meeting, the full board of directors of Amtran met to receive the
single member special independent director committee's recommendation and to
consider taking action on Mikelsons' revised proposal and related matters. After
receiving the favorable recommendation of the single member special independent
director committee and reviewing the terms of the merger agreement and related
documents (including the commitment letters for the financing arrangements and
the ILFC agreement) and the proposed terms of the settlement of the shareholder
litigation, the board of directors of Amtran unanimously voted to approve the
merger proposed by Mikelsons and related matters. Immediately after this board
meeting, the merger agreement was executed and delivered, and Amtran issued a
press release announcing that an agreement had been reached with Mikelsons and
INDUS. Amtran and ATA also executed and delivered the commitment letters for the
financing arrangements during the evening of June 18.

PURPOSE AND STRUCTURE OF THE MERGER

    The purpose of the merger is for Mikelsons to own all the common stock of
Amtran immediately following completion of the merger. In the future, 19 of our
officers may acquire shares of our common stock upon the exercise of stock
options which remain outstanding following the merger (as described under
' -- Interests of Certain Persons in the Merger') and under any stock options
that we may grant in the future. ILFC may also acquire shares of our common
stock in the future through the conversion of all or a portion of its shares of
our Series B preferred stock into shares of our common stock.

    Amtran and the filing persons believe that taking Amtran private at this
time will allow management to focus on the implementation of long-term strategic
goals. In particular, Amtran and the filing persons believe that Amtran's
management should be focusing primarily on implementing Amtran's refleeting
initiative, the implementation of which began with the delivery of the first new
aircraft in June 2001, and the concurrent expansion of Amtran's operations at
Midway Airport in Chicago, Illinois. Amtran and the filing persons believe that
these two initiatives could result in substantial benefits if they are
successfully implemented. However, Amtran and the filing persons recognize that
the implementation of these initiatives involves substantial execution risk, of
which numerous factors that will determine the success of the initiatives are
beyond the control of Amtran and its management, and believe that it will be
several years before the success of these initiatives can be determined. Because
of this substantial uncertainty and time horizon, Amtran and the filing persons
believe that the public equity markets are unlikely to reflect the potential
benefits of these initiatives at any time in the near future.

    Amtran and the filing persons also believe that Amtran is bearing the costs
of being a publicly traded company without enjoying the full benefits usually
associated with being publicly traded. Although Amtran will be required under
its indentures to continue to file periodic reports with the SEC, Amtran's
management estimates that ceasing to have publicly traded equity will reduce its
costs by approximately $125,000 per year through a reduction in costs relating
to investor relations, management resources devoted to equity conferences and
equity research analysts and costs relating to the quotation of its common stock
on the Nasdaq Stock Market. In addition, Amtran and the filing persons believe
that Amtran's stock has historically traded at a discount to its peers based in
part on its limited public float and limited equity analyst coverage.

    As described in ' -- Background of the Merger' above, Amtran, INDUS and
Mikelsons considered alternative means of accomplishing the stated purposes for
the merger. As described above under ' -- Background of the Merger', Messrs.
Tague, Wolff and Hlavacek also participated to varying degrees in the
consideration of alternative means of accomplishing the stated purposes for the
merger. However, these alternatives were ultimately not pursued for the reasons
set forth in ' -- Background of the Merger'.

THE SINGLE MEMBER SPECIAL INDEPENDENT DIRECTOR COMMITTEE


    The Amtran board of directors appointed a special independent director
committee consisting of a single member, Robert A. Abel, to evaluate the
proposed merger. For the purpose of evaluating this going-private transaction,
Mr. Abel is the sole independent member of the Amtran board of directors. All of
the Amtran shares held by Mr. Abel will be cashed out in the same manner as
those held by the Amtran shareholders whose shares are being converted into
cash. All of the stock options held by Mr. Abel will be canceled and exchanged
for cash in the same manner as all other Amtran stock options (other than the
options held by the 19 officers whose options will remain outstanding following
the merger, as described under ' -- Interests of Certain Persons in the
Merger'). Mr. Abel will receive separate compensation in the amount of $50,000
for his service on the single member special independent director committee. In
addition, Mr. Abel will continue as a director of Amtran after the merger and
also will be entitled to certain indemnification rights and to directors' and
officers' liability insurance that will be continued by Amtran following the
merger as described below under ' -- Interests of Certain Persons in the
Merger'. Mr. Abel is a partner in Blue & Co., LLC ('Blue & Co.'), an accounting
firm which has provided tax and accounting services to Amtran, Betaco, Inc.
('Betaco') and Mikelsons in 2000. Blue & Co. billed Amtran $28,310 for tax and
accounting services in 2000. Mikelsons is the sole owner of Betaco. Blue & Co.
billed Betaco $20,835 for tax and accounting services provided to Betaco and
Mikelsons in 2000. Mikelsons has advised us that he currently expects that Blue
& Co. will continue to provide certain tax and accounting services to Amtran,
Betaco and Mikelsons following the merger. Each member of the Amtran board of
directors and the single member special independent director committee believes
that the foregoing arrangements do not affect the single member special
independent director committee's independence or impartiality because (i) the
total amounts received by Blue & Co. from Amtran and Betaco were less than 1% of
Blue & Co.'s total revenues in 2000 and (ii) the total amounts received from
Blue & Co. by Mr. Abel which are attributable to Blue & Co. billings from Amtran
and Betaco were less than 1% of Mr. Abel's income in 2000.


RECOMMENDATIONS OF THE SINGLE MEMBER SPECIAL INDEPENDENT DIRECTOR COMMITTEE AND
BOARD OF DIRECTORS

    On June 18, 2001, the single member special independent director committee,
consisting of the sole independent member of your board of directors for the
purpose of evaluating this transaction, determined that the merger is fair to
and in the best interests of Amtran and the holders of its common stock (other
than Mikelsons and any Mikelsons Affiliate) and recommended that your board of
directors adopt the plan of merger and approve the merger, the merger agreement
and the other transactions contemplated thereby. In making this recommendation,
the single member special independent director committee also considered the
ILFC Agreement and the ILFC Amendment, the Commitment Letter (as defined below)
and the proposed option modification agreements between Amtran and 19 of its
officers.

    At a meeting on June 18, 2001, your board of directors, based on, among
other things, the recommendation of the single member special independent
director committee, unanimously adopted resolutions:

     approving the merger, the merger agreement, the ILFC Agreement and the ILFC
     Amendment;

                                       17

<Page>
     determining that the merger is fair to and in the best interests of Amtran
     and its shareholders, other than Mikelsons and any Mikelsons Affiliate;

     recommending that holders of shares of our common stock, including a
     majority of shares voting at the annual meeting not owned by Mikelsons or
     any Mikelsons Affiliate, approve the merger, the plan of merger and the
     merger agreement; and

     adopting the plan of merger.

    YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE 'FOR' APPROVAL OF THE
MERGER, THE PLAN OF MERGER AND THE MERGER AGREEMENT.

FAIRNESS OF THE MERGER

    On June 18, 2001, the single member special independent director committee
recommended that the board of directors approve the merger, the merger agreement
and the other transactions contemplated thereby and adopt the plan of merger. On
June 18, 2001, the board of directors, by unanimous vote of all directors
present and voting, based upon, among other things, the recommendation and
approval of the single member special independent director committee, adopted
the plan of merger, approved the merger, the merger agreement and the ILFC
Amendment and determined that the merger is fair to and in the best interests of
Amtran and the holders of its shares of common stock (other than Mikelsons and
any Mikelsons Affiliate) and recommended that the shareholders of Amtran approve
the merger, the plan of merger, the merger agreement and the ILFC Amendment.

Single Member Special Independent Director Committee

    In reaching its determinations referred to above, the single member special
independent director committee considered the following factors, each of which,
in the view of the single member special independent director committee,
supported such determinations:

    (i)   the opinion of DrKW that, based upon and subject to the various
          assumptions and limitations set forth therein, as of June 18, 2001,
          the $23.00 per share to be received by holders of shares of Amtran
          common shares other than Mikelsons and his affiliates (the 'Public
          Shareholders') pursuant to the merger agreement was fair to such
          Public Shareholders from a financial point of view, and the report and
          analyses presented to the single member special independent director
          committee in connection therewith (See ' -- Opinion of Financial
          Advisor to the Single Member Special Independent Director Committee');
          a copy of DrKW's opinion is attached hereto as Annex C. Shareholders
          are urged to read this opinion in its entirety. The single member
          special independent director committee adopted the analysis and
          conclusions of DrKW;

    (ii)  the course of the negotiations between the single member special
          independent director committee and its representatives and INDUS and
          its representatives, including (a) that the negotiations resulted in
          an increase in the merger consideration to be received by holders of
          shares of common stock (other than Mikelsons and any Mikelsons
          Affiliate) from $21.00 to $23.00 per share, (b) the single member
          special independent director committee's belief that $23.00 per share
          was the highest price which could be obtained from INDUS and (c) the
          single member special independent director committee's belief that
          further negotiations with INDUS could cause INDUS to abandon the
          merger, with the resulting significant possibility that the market
          price for the shares could fall substantially below $23.00;

    (iii)  the terms and conditions of the merger agreement, including (a) that
           the recommendation of the single member special independent director
           committee may be withdrawn, modified or amended to the extent the
           single member special independent director committee believes it
           necessary to do so in the exercise of its fiduciary duties; (b) the
           requirement that the merger not be consummated unless at least a
           majority of the shares voted by the Public Shareholders vote to
           approve the merger, (c) the

                                       18

<Page>
           condition that Amtran and INDUS use their reasonable best efforts to
           obtain the financing to pay the merger consideration; and (d) the
           limited nature of other conditions to the merger;

    (iv)  that the commitment letter that Amtran and ATA had obtained provided
          for the availability of financing to consummate the merger, subject to
          the terms and conditions in such commitment letter;

    (v)  the historical market prices and recent trading activity of Amtran
         common stock, including that the merger price of $23.00 per share
         represents: (x) a premium of approximately 82.5% over the $12.60 per
         share closing price on May 16, 2001, the last trading day prior to the
         announcement of Mikelsons' proposal; (y) a premium of approximately
         139% over the $9.63 per share closing price 60 days prior to the
         announcement of Mikelsons' proposal; and (z) a premium of approximately
         39.4% over the $16.50 closing price 1 year prior to the announcement of
         Mikelsons' proposal.

    (vi)  the fact that the merger price of $23.00 per share was at or near the
          maximum level which Amtran could pay and remain in compliance with the
          restricted payments covenants of its indentures;


    (vii) the possibility that, because of (x) a possible downturn in the
          airline industry generally, (y) risks arising from Amtran's business
          on a going-forward basis, including risks related to the rapid
          integration of new aircraft and the subsequent disposition of a
          portion of its current fleet, and Amtran management's stated belief
          that based on its knowledge of and experience in the airline industry
          no past airline had successfully moved from the charter service
          business to a predominantly scheduled service business, or (z) a
          decline in the trading price of the shares or the stock market in
          general, the consideration the Public Shareholders would receive
          pursuant to the merger would be more advantageous than the future
          trading price or the consideration the Public Shareholders could
          obtain in a future transaction;


    (viii) the fact that Amtran common stock has historically traded at a
           discount to the stocks of other domestic airlines due to Amtran's
           limited public float; and

    (ix)  the fact that Mikelsons, as sole shareholder of INDUS, has sufficient
          stock ownership to control a disposition of Amtran and that Mikelsons
          indicated that he was not interested in selling control of Amtran to a
          third party or taking on a significant minority partner and that the
          single member special independent director committee and DrKW were not
          authorized to, and did not, solicit third-party indications of
          interest for the acquisition of all or any part of Amtran or its
          assets.

    The single member special independent director committee also considered the
following adverse factors associated with the merger:

    (i)  DrKW's analyses based on some of the projections provided to DrKW by
         Amtran's management had produced implied per share valuations ranging
         from $9.51 up to $94.69 per share;

    (ii) that because Mikelsons had publicly stated his intention to oppose any
         alternative transaction with a third party, Public Shareholders were
         not afforded an opportunity to participate in any control premium that
         might have been generated by the sale of the entire company to a third
         party;

    (iii) that the merger will be a taxable transaction for Amtran shareholders
          whose shares are being converted into cash in the merger;

    (iv) that the cash merger structure of the transaction would take longer to
         complete than a transaction involving a cash tender offer by INDUS for
         the shares of the Public Shareholders followed by a merger of INDUS
         with and into Amtran; and

    (v) that the Public Shareholders of Amtran would have no ongoing equity
        participation in the surviving corporation following the merger, meaning
        that the Public Shareholders would

                                       19

<Page>
        cease to participate in Amtran's future earnings or growth, if any, or
        to benefit from increases, if any, in the value of their common stock in
        Amtran.

    In view of the variety of factors considered by the single member special
independent director committee, the single member special independent director
committee did not find it practicable to, and did not, quantify or otherwise
attempt to assign specific or relative weights to the factors it considered in
reaching its determination. The single member special independent director
committee evaluated the $23 per share offer merger consideration against recent
and historic market prices for the shares of Amtran common stock. The single
member special independent director committee also considered the opinion of
DrKW that, based upon and subject to the various assumptions and limitations set
forth therein, as of June 18, 2001, the $23 per share to be received by the
Public Shareholders pursuant to the merger was fair to such Public Shareholders
from a financial point of view, and the report and analyses presented to the
single member special independent director committee in connection therewith.
The single member special independent director committee adopted DrKW's analysis
of the $23 per share offer against the going concern value of Amtran presented
in the report prepared by DrKW and presented to the single member special
independent director committee in connection with the delivery of its opinion.
See ' -- Opinion of Financial Advisor to the Single Member Special Independent
Director Committee'. Other than as described above, the single member special
independent director committee did not consider any factors regarding the
fairness of the merger to the shareholders of Amtran, other than Mikelsons and
any Mikelsons Affiliate, and believes that the factors it considered provided a
reasonable basis to form its belief. Specifically, the single member special
independent director committee did not independently consider with respect to
such fairness:

     net book value, which the single member special independent director
     committee did not believe had any systematic connection with the economic
     value of Amtran;

     liquidation value, which the single member special independent director
     committee did not view as relevant since it believed that substantial value
     was tied to Amtran as a going concern and that liquidation would destroy
     this value; or

     purchase prices paid by Amtran for past purchases of shares of Amtran
     common stock, which, in recent years, involved too few shares to be used as
     a reliable basis for valuation.

    The single member special independent director committee also considered the
conditional proposals made by Apollo, including the September 2000 proposal and
the April 2001 proposal, in light of the declines in Amtran's projections since
the September 2000 proposal, the fact that even after extensive due diligence
and negotiations during 2000, Apollo was unable to present a proposal that was
acceptable to Mikelsons and that Mikelsons believed could be consummated in a
reasonable period of time. Thus, for the foregoing reasons, to the extent that
any of the Apollo proposals constituted firm offers to acquire all of, or a
controlling interest in, Amtran, the single member special independent director
committee concluded that such proposals were not feasible. See ' -- Background
of the Merger' for a discussion of certain conditional proposals made by Apollo.

    The single member special independent director committee considered the
advantages and disadvantages of the only apparently available alternative to the
acquisition of the public shareholder interest in Amtran by Mikelsons, which was
Amtran continuing as a publicly held company with Mikelsons maintaining his 72%
equity interest in Amtran. In the view of the single member special independent
director committee, the principal advantage of Amtran continuing as a publicly
traded company was that it would allow the Public Shareholders to continue to
participate in any growth in the value of Amtran equity. The disadvantages of
Amtran continuing as a publicly traded company that were considered by the
single member special independent director committee included the exposure to
the risks and uncertainties attendant to continuing as a publicly traded company
in light of risks to Amtran's business from rising fuel prices, rising labor
costs, the rapid integration of new aircraft and the subsequent disposition of a
portion of its current fleet and Amtran management's stated belief that based on
its knowledge of and experience in the airline industry no past airline had
successfully moved from a charter service business to a predominantly scheduled
service business. In addition, the single member special

                                       20

<Page>
independent director committee considered the fact that Amtran common stock has
historically traded at a discount to the stocks of other domestic airlines due
to Amtran's limited public float and the fact that Amtran has a controlling
shareholder. The single member special independent director committee concluded
that under all of the relevant circumstances, and in light of the $23 per share
price in cash, the disadvantages of Amtran continuing as a publicly traded
company significantly outweighed the advantages, and accordingly that
alternative was rejected.

    After consulting with its financial and legal advisors with respect to the
merger, including, without limitation, the factors discussed above, the single
member special independent director committee concluded that the merger was
advisable, fair to and in the best interests of Amtran and the holders of shares
of Amtran common stock (other than Mikelsons and any Mikelsons Affiliate).

    At the June 18, 2001 meeting of the Amtran board of directors, the single
member special independent director committee, with its legal advisors
participating, reported to the other members of the Amtran board of directors on
its review of the merger agreement and the factors taken into account by the
single member special independent director committee in reaching its
determination that the proposed merger is advisable, fair to and in the best
interests of Amtran and the holders of shares of Amtran common stock (other than
Mikelsons and any Mikelsons Affiliate).

Board of Directors

    In reaching its determinations referred to above, the board of directors
considered the following factors, each of which, in the view of the board of
directors, supported its determinations:

     the conclusions and recommendation of the single member special independent
     director committee;

     the factors referred to above as having been taken into account by the
     single member special independent director committee, including the receipt
     by the single member special independent director committee of the opinion
     of DrKW that, based upon and subject to the assumptions and limitations
     stated in the opinion, as of the date of the opinion, the consideration to
     be received by the holders of shares of our common stock (other than
     Mikelsons and his affiliates) in the merger is fair to such holders from a
     financial point of view, and the analyses presented by DrKW to the single
     member special independent director committee, which the board of directors
     hereby adopts; and

     the fact that the terms and conditions of the merger agreement were the
     result of a process that the board of directors believes simulated a
     third-party transaction, which is a transaction in which negotiations are
     conducted at arm's-length and there is no compulsion to reach an agreement,
     between the single member special independent director committee and
     Mikelsons and their respective advisors.

    The members of your board of directors, including the sole member of the
special independent director committee, evaluated the merger in light of their
knowledge of the business, financial condition and prospects of Amtran, and
considered the advice of financial and legal advisors.

    Your board of directors, including the sole member of the special
independent director committee, believes that the merger is procedurally fair
because, among other things:

     the single member special independent director committee consisted of a
     director who is not an employee of Amtran or otherwise an affiliate of
     Mikelsons and who was appointed to represent the interests of the public
     holders of shares of Amtran common stock;

     the single member special independent director committee retained and was
     advised by S&C, its independent legal counsel;

     the single member special independent director committee retained and was
     advised by Sommer & Barnard, its independent Indiana legal counsel;

                                       21

<Page>
     the single member special independent director committee retained and was
     advised by DrKW, its independent financial advisor, to assist it in
     evaluating Mikelsons' proposal;

     the nature of the deliberations pursuant to which the single member special
     independent director committee evaluated the merger and alternative of
     rejecting Mikelsons' proposal;

     the per share price to be paid to public holders of shares of Amtran common
     stock resulted from a process that the board of directors believes
     simulated a third-party transaction, which is a transaction in which
     negotiations are conducted at arm's-length and there is no compulsion to
     reach an agreement, between the single member special independent director
     committee and its financial advisor, on the one hand, and Mikelsons and his
     financial advisor, on the other hand; and

     the merger is structured to require the approval of the holders of a
     majority of the shares of Amtran common stock voting at the annual meeting,
     other than shares held by Mikelsons and any Mikelsons Affiliate,
     notwithstanding the fact that under the IBCL the vote of a majority of the
     outstanding shares of Amtran common stock is sufficient to approve the
     merger.

    In reaching its determination, the board of directors also took into account
the adverse factors considered by the single member special independent director
committee.

    In view of the variety of factors considered by the board of directors, the
board of directors did not find it practicable to, and did not, quantify or
otherwise attempt to assign specific or relative weights to the factors it
considered in reaching its determination. The board of directors evaluated the
$23 per share offer merger consideration against recent and historic market
prices for the share of Amtran common stock. The board of directors also took
account of the opinion of DrKW to the single member special independent director
committee that, based upon and subject to the various assumptions and
limitations set forth therein, as of June 18, 2001, the $23 per share to be
received by the Public Shareholders pursuant to the merger was fair to such
Public Shareholders from a financial point of view, and the report and analyses
presented to the single member special independent director committee in
connection therewith. The board of directors adopted DrKW's analysis of the $23
per share offer against the going concern value of Amtran presented in the
report prepared by DrKW and presented to the single member special independent
director committee in connection with the delivery of its opinion. See
' -- Opinion of Financial Advisor to the Single Member Special Independent
Director Committee'. Other than as described above, the board of directors did
not consider any factors regarding the fairness of the merger to the
shareholders of Amtran, other than Mikelsons and any Mikelsons Affiliate. The
board of directors believes that the factors it considered provided a reasonable
basis to form its belief. Specifically, the board of directors did not
independently consider with respect to such fairness:

     net book value, which the board of directors did not believe had any
     systematic connection with the economic value of Amtran;

     liquidation value, which the board of directors did not view as relevant
     since it believed that substantial value was tied to Amtran as a going
     concern and that liquidation would destroy this value; or

     purchase prices paid by Amtran for past purchases of shares of Amtran
     common stock, which, in recent years, involved too few shares to be used as
     a reliable basis for valuation.

    The board of directors also considered the conditional proposals made by
Apollo, including the September 2000 proposal and the April 2001 proposal, in
light of the declines in Amtran's projections since the September 2000 proposal,
the fact that even after extensive due diligence and negotiations during 2000,
Apollo was unable to present a proposal that was acceptable to Mikelsons and
that Mikelsons believed could be consummated in a reasonable period of time.
Thus, for the foregoing reasons, to the extent that any of the Apollo proposals
constituted firm offers to acquire all of, or a controlling interest in, Amtran,
the board of directors concluded that such proposals were not feasible. See
' -- Background of the Merger' for a discussion of certain conditional proposals
made by Apollo.

    The board of directors considered the advantages and disadvantages of the
only apparently available alternative to the acquisition of the public
shareholder interest in Amtran by Mikelsons, which was Amtran continuing as a
publicly held company with Mikelsons maintaining his 72% equity interest in
Amtran. In the view of the board of directors, the principal advantage of Amtran
continuing as a publicly traded company was that it would allow the Public
Shareholders to continue to participate in any growth in the value of Amtran
equity. The disadvantages of Amtran continuing as a publicly traded company that
were considered by the board of directors included the exposure to the risks and
uncertainties attendant to continuing as a publicly traded company in light of
risks to Amtran's business from rising fuel prices, rising labor costs, the
rapid integration of new aircraft and the subsequent disposition of a portion of
its current fleet, and Amtran management's stated belief that based on its
knowledge of and experience in the airline industry no past airline had
successfully moved from a charter service business to a predominantly scheduled
service business. In addition, the board of directors considered the fact that
Amtran common stock has historically traded at a discount to the stocks of other
domestic airlines due to Amtran's limited public float and the fact that Amtran
has a controlling shareholder. The board of directors concluded that under all
of the relevant circumstances, and in light of the $23 per share price in cash,
the disadvantages of Amtran continuing as a publicly traded company
significantly outweighed the advantages, and accordingly that alternative was
rejected.

    The foregoing discussion of the information and factors considered and given
weight by the single member special independent director committee and the board
of directors is not intended to be exhaustive but is believed to include all
material factors considered by the single member special independent director
committee and your board of directors.

    ON JUNE 18, 2001, YOUR BOARD OF DIRECTORS, BASED ON, AMONG OTHER THINGS, THE
RECOMMENDATION OF THE SINGLE MEMBER SPECIAL INDEPENDENT DIRECTOR COMMITTEE,
UNANIMOUSLY APPROVED THE MERGER, THE MERGER AGREEMENT, THE ILFC AGREEMENT AND
THE ILFC AMENDMENT AND ADOPTED THE PLAN OF MERGER. ON JUNE 18, 2001, THE SINGLE
MEMBER SPECIAL INDEPENDENT DIRECTOR COMMITTEE AND THE BOARD OF DIRECTORS
(a) DETERMINED THAT THE MERGER IS FAIR TO AND IN THE BEST INTERESTS OF AMTRAN
AND ITS SHAREHOLDERS (OTHER THAN MIKELSONS AND ANY MIKELSONS AFFILIATE) AND
(b) RECOMMENDED THAT HOLDERS OF SHARES OF OUR COMMON STOCK (INCLUDING A MAJORITY
OF SHARES VOTING AT THE ANNUAL MEETING NOT OWNED BY MIKELSONS OR ANY MIKELSONS
AFFILIATE) APPROVE THE MERGER, THE PLAN OF MERGER AND THE MERGER AGREEMENT.

PERFORMED BY DRKW, IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF
THE OPINION ATTACHED HERETO AS ANNEX C.

    Although DrKW is under no obligation under its engagement letter to update
its fairness opinion, we believe that DrKW would update its fairness opinion if
requested to do so by the single member special independent director committee.

    In connection with rendering its opinion, DrKW, among other things, (i)
reviewed a draft of the merger agreement, (ii) reviewed and analyzed certain
publicly available business and financial information relating to Amtran for
recent years and interim periods to date, as well as certain internal financial
and operating information, including financial forecasts, analyses and
projections prepared by or on behalf of Amtran and provided to DrKW for purposes
of its analysis, (iii) met with management of Amtran to review and discuss such
information and, among other matters, Amtran's business, operations, assets,
financial condition and future prospects, (iv) reviewed and considered certain
financial and stock market data relating to Amtran, and compared that data with
similar data for certain other companies, the securities of which are publicly
traded, that DrKW believed may be relevant or comparable in certain respects to
Amtran or one or more of its businesses or assets, (v) reviewed and considered
the financial terms of certain recent acquisitions and business combination
transactions in the airline industry specifically, and in other industries
generally, that DrKW believed to be reasonably comparable to the merger or
otherwise relevant to its inquiry and (vi) performed such other financial
studies, analyses, and investigations and reviewed such other information as
DrKW considered appropriate.

    In its review and analysis and in formulating its opinion, DrKW assumed and
relied upon the accuracy and completeness of all of the historical financial and
other information provided to or discussed with it or publicly available, and
DrKW did not assume any responsibility for independent verification of any of
such information. DrKW also assumed and relied upon the reasonableness and
accuracy of the financial projections, forecasts and analyses provided to it,
and DrKW assumed that such projections, forecasts and analyses were reasonably
prepared in good faith and on bases reflecting the best currently available
judgments and estimates of Amtran management. DrKW expressed no opinion with
respect to such projections, forecasts and analyses or the assumptions upon
which they are based. The Amtran board of directors reviewed the historical
financial information, and the financial projections, forecasts and analyses
provided to DrKW and found DrKW's reliance on such materials to be reasonable.
In addition, DrKW did not review any of the books and records of Amtran, or
assume any responsibility for conducting a physical inspection of the properties
or facilities of Amtran, or for making or obtaining an independent valuation or
appraisal of the assets or liabilities of Amtran, and no such independent
valuation or appraisal was provided to DrKW. DrKW also assumed that the
transactions described in the merger agreement would be consummated without
waiver or modification of any of the material terms or conditions contained
therein by any party thereto. DrKW's opinion was necessarily based on economic
and market conditions and other circumstances as they existed and could be
evaluated by it as of the date of such opinion.

    In the context of its engagement, DrKW was not authorized to and did not
solicit third-party indications of interest in acquiring all or any part of
Amtran or its assets, or pursue any alternative transactions which may be
available to Amtran. DrKW expressed no opinion with respect to the values which
may have been obtained for Amtran in a sale to a third party following an
auction process.

    The following is a summary of the report presented by DrKW to the single
member special independent director committee in connection with the delivery of
its opinion on June 18, 2001. Copies of the reports presented by DrKW to the
single member special independent director committee on June 5 and June 18, 2001
have been filed as Exhibits (c)(2) and (c)(3), respectively, to the
Schedule 13E-3 filed with the SEC by Amtran and the filing persons. The summary
set forth below describes all material analyses included in DrKW's reports. The
financial analyses summarized below include information presented in tabular
format. In order to understand the financial analyses fully, the tables must be
read together with the text of each summary.

    DISCOUNTED CASH FLOW ANALYSIS. DrKW performed discounted cash flow ('DCF')
analyses of Amtran based on a base case and five alternative financial forecasts
provided to DrKW by the management of Amtran. The base case considered by DrKW
(the 'Base Case') was predicated on the forecasts for 2001 through 2005 that
were developed by Amtran management in May 2001. The Base Case assumed that
Amtran would succeed in implementing its business plan through 2005, including
most importantly that Amtran would be able to modernize its fleet successfully
by adding 49 new aircraft and replacing a number of older aircraft while growing
its scheduled service business. DrKW also considered five alternative cases that
Amtran management prepared at DrKW's request: (i) a maintenance adjustment case
(the 'Maintenance Case') which adjusted the Base Case to account for, on a
straight line basis, certain deferred maintenance expenses related to newly
acquired aircraft which Amtran projects that it would be required to pay for in
the period from 2001 through 2010, (ii) a fuel adjustment case (the 'Fuel
Adjustment Case') which adjusted the Base Case to reflect an assumption that jet
fuel costs would remain at the 2001 level of $0.989 per gallon instead of
declining to $0.891 per gallon by 2003, (iii) an increased competition case (the
'Enhanced Competition Case') which adjusted the Base Case to reflect an
assumption that competition with its direct competitors in Midway Airport would
cause fares to fall by 5% in those markets where Amtran and those competitors
directly compete, other than Los Angeles, where fares were assumed to decline by
10%, (iv) a recession case (the 'Recession Case') which adjusted the Base Case
to reflect an assumption that the average revenue per seat mile for Amtran
scheduled service business would remain at the year 2000 level of 7.44 cents
rather than increasing at a compounded growth rate of 2.0% and (v) a downside
case (the 'Downside Case') which adjusted the Base Case to reflect the
simultaneous occurrence of the Recession Case, the Enhanced Competition Case and
the Fuel Adjustment Case.


    In performing the DCF analyses, DrKW, using the forecasts as described
above, discounted Amtran's unlevered free cash flows, which is net income before
interest, taxes and losses incurred on the sale of aircraft (tax-effected), plus
depreciation and amortization, plus cash proceeds from the sale of aircraft,
less increases in working capital, less capital expenditures over the specified
forecast period using a range of risk adjusted discount rates between 11.0% and
13.0%. The sum of the present values of such free cash flows for Amtran was then
added to the present value of the terminal value of Amtran's earnings before
interest, taxes, depreciation and amortization ('EBITDA') for 2005 computed
using a forward multiple range of EBITDA of 4.0x to 5.5x. Based on this
analysis, DrKW calculated the following implied price per share ranges.


<Table>

                                               EBITDA TERMINAL VALUE MULTIPLE

Base....................  $22.13 to $25.08   $25.06 to $28.26   $27.99 to $31.43   $30.92 to $34.60
Maintenance.............  $17.71 to $20.60   $20.60 to $23.51   $23.28 to $26.42   $25.96 to $29.33
Fuel Adjustment.........  $11.81 to $14.35   $14.26 to $17.01   $16.71 to $19.66   $19.17 to $22.06
Enhanced Competition....  $15.17 to $17.95   $17.88 to $20.76   $20.49 to $23.39   $22.92 to $26.02
</Table>

The Recession Case and the Downside Case both resulted in negative discounted
cash flow ranges at each of the discount rates.

    In reviewing the DCF analyses for the purposes of its determination of
fairness, DrKW took into consideration the fact that certain analyses for the
Base Case, Maintenance Case and Enhanced Competition Case resulted in implied
per share DCF value ranges greater than $23.00 per share of Amtran common stock.
As discussed below, DrKW believes that its analyses must be considered as a
whole and that selecting portions of its analyses, without considering the
analyses taken as a whole, would create an incomplete view of the process
underlying the analyses performed in reaching its opinion. In addition, DrKW
considered the results of all such analyses and did not assign relative weights
to any of the analyses, so that the ranges of valuations resulting from any
particular analysis described above should not be taken to be DrKW's view of the
actual value of Amtran.

    COMPARABLE COMPANIES TRADING ANALYSIS. DrKW reviewed and compared certain
financial information of Amtran to corresponding financial information for the
following six publicly traded major domestic airlines (the 'Major Domestic
Airlines'):

                                       25

<Page>
     American Airlines, Inc.

     Continental Airlines, Inc.

     Delta Air Lines, Inc.

     Northwest Airlines Corporation

     Southwest Airlines Co.

     UAL Corporation

    DrKW also reviewed and compared certain financial information of Amtran to
corresponding financial information for the following four publicly traded
regional and discount domestic airlines (the 'Regional and Discount Domestic
Airlines):

     AirTran Holdings, Inc.

     Alaska Air Group, Inc.

     America West Holdings Corporation

     Frontier Airlines, Inc.

    DrKW calculated and compared various financial multiples and ratios. The
multiples and ratios were calculated using the closing price for the common
stock of Amtran and each of the selected companies on June 15, 2001 and were
based on the most recent publicly available information. The estimated year 2001
and 2002 financial results for Amtran were from the Base Case described above in
' -- Discounted Cash Flow Analysis'. DrKW calculated the following multiples:

     market equity value as a multiple of net income for (i) the latest 12
     months, (ii) estimated year 2001 and (iii) estimated year 2002;

     market equity value as a multiple of book value for (i) the latest 12
     months, (ii) estimated year 2001 and (iii) estimated year 2002;

     adjusted market value, which is market value plus debt less cash, as a
     multiple of sales for (i) the latest 12 months, (ii) estimated year 2001
     and (iii) estimated year 2002;


     adjusted market value as a multiple of EBITDA for (i) the latest 12 months,
     (ii) estimated year 2001 and (iii) estimated year 2002;


     adjusted market value as a multiple of EBITDA, as adjusted for engine
     overhaul costs for (i) the latest 12 months, (ii) estimated year 2001 and
     (iii) estimated year 2002;

     lease-adjusted market value (defined as adjusted market value plus the
     capitalized value of aircraft leases) as a multiple of earnings before
     interest, taxes, depreciation and amortization and rent ('EBITDAR') for (i)
     the latest 12 months, (ii) estimated year 2001 and (iii) estimated year
     2002;

     adjusted market value as a multiple of earnings before interest and taxes
     ('EBIT') for (i) the latest 12 months, (ii) estimated year 2001 and
     (iii) estimated year 2002; Such analyses for the Major Domestic Airlines
     are summarized below:

    DrKW used these comparable company multiples, excluding certain multiples
which DrKW determined were not meaningful, to calculate implied values for the
shares based on the medians of multiples derived from such transactions. The
analysis produced an implied per share price, based on the mean of the Major
Domestic Airlines' multiples, of,

     (i) for the latest twelve months, $16.41 based on book value, $24.79 based
     on sales, $16.19 based on EBITDA, and $14.64 based on EBITDAR,

     (ii) for the estimated year 2001, $13.70 based on book value, $25.22 based
     on sales, $54.59 based on EBITDA, $8.25 based on Adjusted EBITDA and $70.98
     based on EBITDAR, and

     (iii) for the estimated year 2002, $11.25 based on book value, $35.24 based
     on sales, $33.88 based on EBITDA, $14.71 based on Adjusted EBITDA and
     $91.90 based on EBITDAR.

    The analysis also produced an implied per share price, based on the mean of
the Regional and Discount Domestic Airlines' multiples, of,

     (i) for the latest twelve months, $16.68 based on book value, $15.55 based
     on sales, $59.66 based on EBITDA, $1.63 based on Adjusted EBITDA and $57.50
     based on EBITDAR,

     (ii) for the estimated year 2001, $13.41 based on book value, $15.96 based
     on sales, $36.99 based on EBITDA, $2.67 based on Adjusted EBITDA and $62.16
     based on EBITDAR, and

     (iii) for the estimated year 2002, $10.56 based on book value, $18.21 based
     on sales, $16.04 based on EBITDA, $13.59 based on Adjusted EBITDA and
     $94.69 based on EBITDAR.

    In reviewing the comparable companies trading analysis for the purposes of
its determination of fairness, DrKW took into consideration the fact that
certain of the analyses produced implied per share values greater than $23.00
per share. DrKW believes that the wide range of implied share values resulting
from the comparable companies trading analysis are the result of differences in
fleet composition, fleet size, leverage, competitive factors and cost structures
among different airlines. As discussed below, DrKW believes that its analyses
must be considered as a whole and

                                       28

<Page>
that selecting portions of its analyses, without considering the analyses taken
as a whole, would create an incomplete view of the process underlying the
analyses performed in reaching its opinion. In addition, DrKW considered the
results of all such analyses and did not assign relative weights to any of the
analyses, so that the ranges of valuations resulting from any particular
analysis described above should not be taken to be DrKW's view of the actual
value of Amtran.

    COMPARABLE TRANSACTIONS ANALYSIS. DrKW reviewed transactions in the airline
industry from March 20, 1997 until March 9, 2001. For each transaction, DrKW
calculated the multiple of the adjusted purchase price, which is the purchase
price attributable to the equity interest of the target company plus the target
company's debt less cash, paid in each transaction as a multiple of the target's
(i) latest 12 months' sales, (ii) latest 12 months' EBITDA and (iii) latest 12
months' EBIT, and the purchase price attributable to the equity interest of the
target company to the target's (iv) latest 12 months' net income, and (v) book
value.

    The analysis of these transactions, excluding certain multiples which DrKW
determined were not meaningful, yielded a range of multiples of adjusted
purchase price to (i) latest 12 months' sales of 0.1x to 3.0x, (ii) latest 12
months' EBITDA of 2.5x to 22.9x, and (iii) latest 12 months' EBIT of 3.3x to
12.9x, and a range of multiples of purchase price to (iv) latest 12 months' net
income of 3.3x to 33.0x, and (v) book value of 0.6x to 4.1x. DrKW used these
comparable transaction multiples to calculate implied values for the shares
based on the ranges of multiples derived from such transactions. The per share
value, based on the median of these values, ranged from $20.73 to $46.08.

    In reviewing the comparable transactions analysis for the purposes of its
determination of fairness, DrKW took into consideration the fact that certain of
the analyses produced implied per share values greater than $23.00 per share. As
discussed below, DrKW believes that its analyses must be considered as a whole
and that selecting portions of its analyses, without considering the analyses
taken as a whole, would create an incomplete view of the process underlying the
analyses performed in reaching its opinion. In addition, DrKW considered the
results of all such analyses and did not assign relative weights to any of the
analyses, so that the ranges of valuations resulting from any particular
analysis described above should not be taken to be DrKW's view of the actual
value of Amtran.

    PRESENT VALUE OF HYPOTHETICAL FUTURE STOCK PRICE ANALYSIS. DrKW performed a
present value of hypothetical future stock price analysis using the Base Case
and the Maintenance Case in order to derive an implied equity value reference
range for Amtran. The future stock price range was determined by applying a P/E
multiple range of 8.0x-12.0x. These P/E multiples were chosen because they were
within the range of historic P/E trading multiples for the shares of Amtran and
the comparable companies. This hypothetical future stock price was then
discounted at a levered cost of equity ranging from 15%-20%. These discount
rates were chosen to reflect market risks, the premiums associated with
micro-cap stocks, the presence of a controlling shareholder and the high degree
of uncertainty surrounding the implementation of Amtran's long-term strategic
goals. The per share value implied by this analysis for the Base Case ranged
from $17.07 to $39.02 with a mean of $23.64 and a median of $22.49. The per
share value implied by this analysis for the Maintenance Case ranged from $9.51
to $31.26 with a mean of $17.33 and a median of $15.18.

    LEVERAGED RECAPITALIZATION ANALYSIS. DrKW also performed an analysis of
Amtran's ability to finance, by incurring additional debt, the repurchase of
approximately 3.1 million shares, representing the shares held by the Public
Shareholders, and the cash out of options at various repurchase prices. This
analysis implied that Amtran could reasonably incur additional debt to finance
the purchase of approximately 3.1 million shares and cash out certain options at
a purchase price of $23.00 per share as contemplated by the terms of the merger.
However, DrKW's opinion did not address the solvency of Amtran following
consummation of the merger, or at any time, nor did DrKW address issues
regarding fraudulent conveyance or fraudulent transfer, and DrKW has been
advised that Amtran has arranged to receive an opinion with respect to all of
such matters from Houlihan, Lokey, Howard and Zukin.

    STOCK PRICE AND PREMIUM ANALYSIS. DrKW reviewed 32 acquisition transactions
by majority shareholders of publicly held minority interests with values ranging
from $73 million to $2.7 billion

                                       29

<Page>
to derive a range of premiums paid over the public trading prices per share one
day, one week and four weeks prior to the announcement of such transactions
since January 1, 1997. In connection therewith, DrKW noted, among other things,
that (i) the reasons for, and circumstances surrounding, each of the
transactions analyzed were diverse, (ii) the characteristics of the companies
and parties involved were not necessarily comparable to those of Amtran and
INDUS and (iii) premiums fluctuate based on perceived growth, synergies,
strategic value, the type of consideration utilized in the transaction,
information in the securities markets and other factors.

    The results of these analyses are summarized below:

</Table>

The $23.00 price also represents a premium of 39.4% over the $16.50 closing
price of the shares one year prior to the announcement date, a time when the
shares of airline stocks in general were trading at higher levels than they are
currently trading.

    CERTAIN GENERAL MATTERS. No company or transaction used in the foregoing
analyses was substantially comparable to Amtran or the merger. In addition,
those analyses and the discounted cash flow analyses are based and are heavily
dependent upon, among other factors, assumptions as to future performance and
other factors, and are therefore subject to the limitations described in DrKW's
opinion. Accordingly, an analysis of the results of the foregoing is not
entirely mathematical; rather, it involves complex considerations and judgments
concerning differences in financial and operating characteristics of the
companies and other factors that could affect the acquisition value or the
public trading value of the companies to which they are being compared and
Amtran.

    A fairness analysis is a complex process and is not necessarily susceptible
to a partial analysis or summary description. DrKW believes that its analyses
must be considered as a whole and that selecting portions of its analyses,
without considering the analyses taken as a whole, would create an incomplete
view of the process underlying the analyses performed in reaching its opinion.
In addition, DrKW considered the results of all such analyses and did not assign
relative weights to any of the analyses, so that the ranges of valuations
resulting from any particular analysis described above should not be taken to be
DrKW's view of the actual value of Amtran. There were no specific factors in
DrKW's analysis which did not support its fairness opinion.

    The analyses performed by DrKW are not necessarily indicative of actual
values, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as part of DrKW's engagement by the
single member special independent director committee. The analyses do not
purport to be appraisals or to reflect the prices at which a company might
actually be sold.

    The single member special independent director committee retained DrKW based
upon its experience and expertise. DrKW is an internationally recognized
investment banking and advisory firm. DrKW, as part of its investment banking
business, is continuously engaged in the valuation of businesses and securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. In the
course of its market-making and other trading activities, DrKW and its
affiliates may, from time to time, have a long or short position in, and may buy
and sell, securities of Amtran.

    Other than receiving instructions from Mr. Abel in his capacity as the sole
member of the special independent director committee, DrKW did not receive any
instructions from Amtran, Mikelsons, INDUS or any other affiliate of Mikelsons.

                                       30

    DRKW ENGAGEMENT AGREEMENT. Pursuant to the terms of a letter agreement,
dated May 8, 2001, between DrKW and Amtran (the 'DrKW Letter Agreement'), the
single member special independent director committee retained DrKW to serve as
its financial advisor with respect to any transaction considered by the single
member special independent director committee pursuant to which Mikelsons or any
affiliate acquires all of the outstanding capital stock of Amtran held by the
Public Shareholders (the 'Proposal'). The DrKW Letter Agreement provides that
Amtran will pay DrKW $100,000 upon the execution of the DrKW Letter Agreement
and $800,000 at such time as DrKW rendered an opinion to the single member
special independent director committee with respect to the adequacy or fairness
from a financial point of view of the consideration to be paid pursuant to the
proposal, or at such time as DrKW advises the single member special independent
director committee that it is unable to render such an opinion. In addition,
pursuant to the terms of an indemnification agreement, dated May 8, 2001, Amtran
is obligated to indemnify DrKW (and its affiliates, their respective directors,
officers, agents, employees and controlling persons) against certain liabilities
arising out of or in connection with DrKW's engagement, including liabilities
under the federal securities laws.

    This summary is not a complete description of the analysis performed by DrKW
and is qualified by reference to the written opinion of DrKW set forth in
Annex C to this proxy statement and to DrKW's report to the single member
special independent director committee included as Exhibit (c)(2) to the
Schedule 13E-3 filed with the SEC on June 29, 2001, and as subsequently amended,
by Amtran and the filing persons, of which this proxy statement constitutes a
part. Copies of DrKW's reports to the single member special independent director
committee on June 5 and June 18, 2001 will be made available for inspection and
copying at our principal executive offices during our regular business hours by
any interested holder of shares of our common stock or representative of any
such holder (who has been so designated in writing). We will also furnish by
mail copies of DrKW's reports to the single member special independent director
committee to any interested holder of shares of our common stock or
representative of any such holder (who has been so designated in writing) upon
written request and at the expense of the requesting holder of shares of our
common stock.

POSITION OF THE FILING PERSONS REGARDING FAIRNESS OF THE MERGER

    The filing persons believe that the merger is fair to and in the best
interests of the holders of shares of our common stock (other than the filing
persons). The filing persons base their belief on the following factors, each of
which, in their view, supported that conclusion:

     the conclusions and recommendation of the single member special independent
     director committee and its analysis of which the filing persons hereby
     expressly adopt;

     the factors referred to above as having been taken into account by the
     single member special independent director committee and the board of
     directors, including that the single member special independent director
     committee received an opinion from DrKW that, as of the date of that
     opinion and subject to the assumptions and limitations discussed in that
     opinion, the consideration of $23 in cash per share of common stock to be
     received by the holders of shares of our common stock (other than Mikelsons
     and any Mikelsons Affiliate) in the merger is fair to such holders from a
     financial point of view, which the filing persons hereby expressly adopt;

     the merger price represents a premium of (a) 82.5% to the closing price of
     Amtran common stock on May 16, 2001, the last trading day prior to
     announcement of Mikelsons' proposal, (b) 122.4% to the closing price of
     Amtran common stock on May 9, 2001, one week prior to the announcement of
     Mikelsons' proposal and (c) 130.9% to the closing price of Amtran common
     stock on April 16, 2001, four weeks prior to the announcement of Mikelsons'
     proposal, which, in each case, exceeds the median premiums paid in other
     minority buy-out transactions; as contained in DrKW's presentation to the
     single member special independent director committee, the median premiums
     paid in other minority buy-out transactions are: (a) 26% for one day prior
     to announcement, (b) 29% for one week prior to announcement and (c) 31% for
     four weeks prior to announcement;

                                       31

<Page>
     the difficulty of forecasting Amtran's performance over a 5-year period in
     light of the degree of variability and uncertainty inherent in the airline
     industry;

     $23 per share exceeds the average price per share paid by Amtran for shares
     of its common stock during the past two years and, in particular, the price
     per share paid by Amtran in purchases of shares of its common stock since
     the third quarter of 1999; see 'Prior Stock Purchases' for information
     concerning prior stock purchases by Amtran; and

     declines in revenues and operating performance of Amtran and other domestic
     airlines during the first two fiscal quarters of 2001.

    In reaching their determinations that the merger is fair, the filing persons
also recognized and considered the adverse factors considered by the single
member special independent director committee. Additionally, the filing persons
considered Mikelsons' lack of interest in selling his shares of Amtran common
stock and that, as a result, the minority shareholders of Amtran would not have
an opportunity to receive a control premium with respect to their shares of
Amtran common stock.

    In view of the variety of factors considered by the filing persons, they did
not find it practicable to, and did not, quantify or otherwise attempt to assign
specific or relative weights to the factors considered in reaching their
determinations. The filing persons evaluated the $23 per share merger
consideration against recent and historic market prices for the shares of Amtran
common stock. The filing persons also took account of the opinion of DrKW to the
single member special independent director committee that, based upon and
subject to the various assumptions and limitations set forth therein, as of June
18, 2001, the $23 per share to be received by the Public Shareholders pursuant
to the merger was fair to such Public Shareholders from a financial point of
view, and the report and analyses presented to the single member special
independent director committee in connection therewith. The filing persons
adopted DrKW's analysis of the $23 per share offer against the going concern
value of Amtran presented in the report prepared by DrKW and presented to the
single member special independent director committee in connection with the
delivery of its opinion. See ' -- Opinion of Financial Advisor to the Single
Member Special Independent Director Committee'. Other than as described above,
the filing persons did not consider any factors regarding the fairness of the
merger to the shareholders of Amtran, other than the filing persons. The filing
persons believe that the factors they considered provided a reasonable basis to
form their belief. Specifically, the filing persons did not independently
consider with respect to such fairness:

     net book value, which the filing persons did not believe had any systematic
     connection with the economic value of Amtran; or

     liquidation value, which the filing persons did not view as relevant since
     they believed that substantial value was tied to Amtran as a going concern
     and that liquidation would destroy this value.

    The filing persons also considered the conditional proposals made by Apollo,
including the September 2000 proposal and the April 2001 proposal, in light of
the declines in Amtran's projections since the September 2000 proposal, the fact
that even after extensive due diligence and negotiations during 2000, Apollo was
unable to present a proposal that was acceptable to Mikelsons and that Mikelsons
believed could be consummated in a reasonable period of time. Thus, for the
foregoing reasons, to the extent that any of the Apollo proposals constituted
firm offers to acquire all of, or a controlling interest in, Amtran, the filing
persons concluded that such proposals were not feasible. See ' -- Background of
the Merger' for a discussion of certain conditional proposals made by Apollo.

    The filing persons considered the advantages and disadvantages of the
alternative to the acquisition of the public shareholder interest in Amtran by
Mikelsons, which was Amtran continuing as a publicly held company with Mikelsons
maintaining his 72% equity interest in Amtran. In the view of the filing
persons, the principal advantage of Amtran continuing as a publicly traded
company was that it would allow public shareholders to continue to participate
in any growth in the value of Amtran equity. The disadvantages to public
shareholders of Amtran

                                       32

<Page>
continuing as a publicly traded company that were considered by the filing
persons included the exposure to the risks and uncertainties attendant to
continuing as a publicly traded company in light of risks to Amtran's business
from rising fuel prices, rising labor costs, the rapid integration of new
aircraft and the subsequent disposition of a portion of its current fleet, and
Mikelsons' and Amtran management's stated belief that based on their knowledge
of and experience in the airline industry no past airline had successfully moved
from a charter service business to a predominantly scheduled service business.
In addition, the filing persons considered the fact that Amtran common stock has
historically traded at a discount to the stocks of other domestic airlines due
to Amtran's limited public float and the fact that Amtran has a controlling
shareholder.

    As described in ' -- Background of the Merger', Mikelsons and INDUS
considered alternative means of accomplishing the stated purposes for the
merger. As described above under ' -- Background of the Merger', Messrs. Tague,
Wolff and Hlavacek also participated to varying degrees in the consideration of
alternative means of accomplishing the stated purposes for the merger. However,
these alternatives were ultimately not pursued for the reasons set forth in ' --
Background of the Merger'. The filing persons believe that taking Amtran private
at this time will allow management to focus on the implementation of long-term
strategic goals. In particular, the filing persons believe that Amtran's
management should be focusing primarily on implementing Amtran's refleeting
initiative, the implementation of which began with the delivery of the first new
aircraft in June 2001, and the concurrent expansion of Amtran's operations at
Midway Airport in Chicago, Illinois. The filing persons believe that these two
initiatives could result in substantial benefits if they are successfully
implemented. However, the filing persons recognize that the implementation of
these initiatives involves substantial execution risk, and that a number of
factors that will determine the success of the initiatives are beyond the
control of Amtran and its management. The filing persons also believe that it
will be several years before the success of these initiatives can be determined.
Because of this substantial uncertainty and time horizon, the filing persons
believe that the public equity markets are unlikely to reflect the potential
benefits of these initiatives at any time in the near future.

    After consulting with Mikelsons' financial and legal advisors with respect
to the merger, including, without limitation, the factors discussed above, the
filing persons concluded that the merger was fair to and in the best interests
of the holders of shares of Amtran common stock (other than the filing persons).

    Although Salomon Smith Barney provided financial advisory services to
Mikelsons in connection with the merger, Salomon Smith Barney was not requested
to, and did not, evaluate or render an opinion or report as to the fairness,
from a financial point of view, of the consideration per share to be paid in the
merger. Salomon Smith Barney's role in the merger consisted primarily of
advising Mikelsons and INDUS on the general strategy for accomplishing the
transaction, including the financing of the transaction and restructuring of the
ILFC Series B preferred stock, reviewing DrKW's and Amtran's financial analyses,
reviewing historical and projected financial information prepared by Amtran's
management and participating in negotiations.

    The filing persons believe that the merger is procedurally fair to and in
the best interests of the holders of shares of Amtran common stock (other than
the filing persons) for the reasons set forth above under ' -- Fairness of the
Merger -- Board of Directors', which the filing persons hereby expressly adopt.

    This discussion of the information and factors considered and given weight
by the filing persons is not intended to be exhaustive but is believed to
include all material factors considered by the filing persons.

PROJECTIONS

    Amtran management produces 5-year plans as part of its ongoing strategic
planning process. These 5-year plans are periodically updated by Amtran's
management. On May 18, 2001, Amtran management provided a version of this 5-year
plan dated May 16, 2001, to DrKW, the single

                                       33

<Page>
member special independent director committee, Salomon Smith Barney, Citicorp
and Bank One, NA. Prior drafts and versions of this plan were supplied to the
same parties.

    On May 25, 2001, representatives of DrKW requested that Amtran management
prepare additional 5-year plans containing various scenarios different from
those contained in management's base case. During the preparation of those
alternative cases on May 29, 2001, Amtran management discovered a calculation
error in the model used in the preparation of the May 16 plan. Copies of this
plan, which is identical to the May 16 plan other than changes resulting from of
the correction of the calculation error, were made available to Salomon Smith
Barney, Citicorp, DrKW and the single member special independent director
committee on May 31, 2001. The base case contained in the May 31 plan contained
the following estimates of Amtran's future (i) operating revenues,
(ii) earnings before interest, taxes, depreciation, amortization and rents,
(iii) earnings before interest, taxes, depreciation and amortization and
(iv) net income:

    On May 31, 2001, Amtran management also provided copies of the 5-year plans
reflecting the various scenarios to Salomon Smith Barney, DrKW and the single
member special independent director committee. The alternative scenarios
presented by Amtran management included:

    Maintenance adjustment. This plan reflects the adjustment of the maintenance
expenses throughout the period covered to reflect the fact that maintenance
costs will be abnormally low during the period from 2002 to 2005 due to the
rapid transition to a younger fleet. The maintenance adjusted plan contains the
following estimates of Amtran's future (i) operating revenues, (ii) earnings
before interest, taxes, depreciation, amortization and rents, (iii) earnings
before interest, taxes, depreciation and amortization and (iv) net income:

    Fuel adjustment: This plan assumes that fuel costs remain at constant levels
throughout the five-year period covered (rather than the assumption that fuel
costs will decline during that period which is the assumption contained in the
base case). The fuel adjusted plan contains the following estimates of Amtran's
future (i) operating revenues, (ii) earnings before interest, taxes,
depreciation, amortization and rents, (iii) earnings before interest, taxes,

    Enhanced competition adjustment: This plan assumes that in response to
Amtran's expansion at Midway Airport and refleeting, Amtran's competitors
increase their level of direct competition with Amtran (as reflected by 5-10%
reductions in Amtran's fare levels from the base case beginning in 2002 on
routes on which it competes directly with its largest competitors at Midway).
The enhanced competition scenario contains the following estimates of Amtran's
future (i) revenues, (ii) earnings before interest, taxes, depreciation,
amortization and rents, (iii) earnings before interest, taxes, depreciation and
amortization and (iv) net income:

    Recession adjustment: This plan assumes that there is a recession during the
5-year period (as reflected by assuming that revenue per available seat mile
would remain at the year-2000 level in 2001 and 2002). The recession adjusted

    Certain information concerning the projections. Amtran does not as a matter
of course make public its projections as to future performance or earnings. The
projections referred to above were not prepared with a view to public
disclosure, and are included in this proxy statement because such information
was not otherwise publicly available and was provided to Mikelsons, Salomon
Smith Barney, Citicorp, Bank One, NA, the alternative financial advisor, DrKW
and the single member special independent director committee. The projections
were not prepared with a view to compliance with published guidelines of the
SEC, the guidelines established by the American Institute of Certified Public
Accountants regarding projections or forecasts, or generally accepted accounting
principles. Neither the independent auditors of Amtran, nor any other
independent accountants, have compiled, examined or performed any procedures
with respect to the projections.

                                       35

<Page>
The projections were not prepared with the approval of the Amtran board of
directors or the single member special independent director committee.

    The projections are forward-looking statements that are subject to certain
risks and uncertainties and should be read with caution. See 'Cautionary
Statement Concerning Forward-Looking Information' in this proxy statement. The
projections are subjective in many respects and thus susceptible to
interpretation and periodic revision based on actual experience and recent
developments. While presented with numeric specificity, the projections reflect
numerous assumptions made by Amtran's management with respect to its refleeting
initiative, the expansion of its operations at Midway Airport, fuel prices,
industry performance and competition, general business, economic, market and
financial conditions and other matters, including assumed interest rates and
effective tax rates consistent with historical levels for Amtran, all of which
are difficult to predict, many of which are beyond Amtran's control.
Accordingly, it is highly likely that Amtran's actual performance will vary from
the assumptions made in preparing the projections and that the variations will
be both substantial and material to the forecasted results. As a result, actual
results may be materially greater or less than those contained in the
projections.

    For these reasons, the inclusion of the projections in this document should
not be regarded as an indication that Amtran, any recipient of the projections
or their respective affiliates or representatives, considered or consider the
projections to be a reliable prediction of future events, and the projections
should not be relied upon as such. None of Mikelsons, INDUS or Messrs. Tague,
Wolff and Hlavacek or any of their respective affiliates or representatives has
made, or makes, any representation to any person regarding the information
contained in the projections. Except to the extent required under the federal
securities laws, Amtran does not intend to make publicly available any update or
other revisions to the projections to reflect circumstances existing after the
date of the preparation of the projections or the occurrence of future events
even in the event that any or all of the assumptions are shown to be in error.

PLANS FOR AMTRAN AFTER THE MERGER

    Mikelsons presently intends to continue to own all the common stock of
Amtran after the merger (other than shares of our common stock which may be
issued in the future upon the exercise of stock options or the conversion of
shares of Series B preferred stock) and for Amtran to continue to operate as a
holding company for its operating subsidiaries.

    Except as otherwise described in this proxy statement, none of Amtran, to
Amtran's knowledge, any of its directors or executive officers or the filing
persons has any current plans or proposals or negotiations which relate to or
would result in:

     other than the merger pursuant to the merger agreement, any extraordinary
     transaction, such as a merger, reorganization or liquidation involving
     Amtran or its subsidiaries;

     any purchase, sale or transfer of a material amount of assets of Amtran or
     its subsidiaries;

     any change in the management of Amtran or any change in any material term
     of the employment contract of any executive officer; or

     any other material change in the corporate structure or business of Amtran.

    Nevertheless, Amtran may initiate from time to time reviews of its assets,
corporate structure, capitalization, operations, properties, management and
personnel to determine what changes, if any, would be desirable following the
merger. Amtran expressly reserves the right to make any changes that it deems
necessary or appropriate in light of its review or in light of future
developments.

CERTAIN EFFECTS OF THE MERGER


    As a result of the merger, Mikelsons will own all the common stock of the
surviving corporation (other than shares of our common stock which may be issued
in the future upon the exercise of stock options or the conversion of Series B
preferred stock). The outstanding preferred stock of Amtran, which consists of
the Series A1 preferred stock, without par value, and the Series B preferred
stock, will remain outstanding. As of September 5, 2001, there were outstanding


                                       36

<Page>

500 shares of Series A1 preferred stock, all held by Boeing Capital Corporation
and 300 shares of Series B preferred stock, all held by ILFC. Following the
merger, holders of shares of Amtran common stock other than Mikelsons, officers
of Amtran (who may acquire shares of our common stock in the future upon the
exercise of stock options) and ILFC (who may acquire shares of our common stock
in the future upon conversion of shares of Series B preferred stock) will no
longer benefit from any increases in the value of the surviving corporation and
will no longer bear the risk of any decreases in the value of the surviving
corporation. In addition, following the merger, the interest of Mikelsons in the
net book value and net income or loss of the surviving corporation will increase
to 100% from a current level of approximately 72%. Following the merger, in
dollar terms, Mikelsons' interest in Amtran's net book value as of the end of
the quarter ended June 30, 2001 will increase to $125.5 million from $91.0
million and his interest in Amtran's 2000 fiscal year net loss will increase to
$15.7 million from $10.9 million. Following the merger, the interests of Messrs.
Tague, Wolff and Hlavacek in the net book value and net income or loss of the
surviving corporation will decrease to 0% from current levels of approximately
0.099%, 0.1% and 0.5%, respectively. Following the merger, in dollar terms, the
interests of Messrs. Tague, Wolff and Hlavacek in Amtran's book value as of the
end of the quarter ended June 30, 2001 will decrease to $0 from approximately
$113,000, $125,000 and $627,000, respectively, and their interests in Amtran's
2000 fiscal year net loss will decrease to $0 from approximately $14,000,
$16,000 and $79,000, respectively. These three officers may acquire interests in
the surviving corporation's net book value and net income or loss in the future
upon the exercise of their stock options which will remain outstanding following
the merger. See ' -- Interests of Certain Persons in the Merger -- Treatment of
Stock Options' in this proxy statement.



    As a result of the merger, all outstanding options to acquire shares of our
common stock other than those held by 19 officers of Amtran will be canceled.
All unvested stock options issued to our officers and certain stock options
issued to non-officers automatically vested upon the approval of the merger by
your board of directors. The compensation committee of your board of directors
has adopted a resolution providing that all stock options (other than those held
by the 19 officers whose options will remain outstanding following the merger)
that are outstanding immediately prior to the closing of the merger will be
canceled in exchange for a cash payment equal to the excess, if any, of $23 over
the exercise price of those options multiplied by the number of shares of our
common stock covered by those options, and that all outstanding stock options
with an exercise price in excess of $23 per share will be canceled without any
cash payment. In the aggregate, our employees (other than the 19 officers
described in the following paragraph) held as of September 4, 2001 options to
purchase 520,015 shares of Amtran common stock with an average exercise price of
$11.87 per share.


    We have agreed in the merger agreement to enter into option modification
agreements with 19 of our officers (including Messrs. Tague, Wolff and Hlavacek)
providing that these officers will not exercise their options prior to the
merger and that their stock options will remain outstanding following the
merger. In the aggregate, these 19 officers hold options to purchase 1,749,464
shares of Amtran common stock with an average exercise price of $11.31. The
terms of the modifications to the stock options of these 19 Amtran officers are
fully described in this proxy statement under the heading ' -- Interests of
Certain Persons in the Merger'.

    Following the merger, Mikelsons, the remaining optionholders and ILFC (upon
conversion of their shares of Series B preferred stock) will benefit from any
increases in the value of Amtran and also bear the risk of any decreases in the
value of Amtran.

    Shares of our common stock will cease to be authorized to be quoted on the
Nasdaq following the merger and will, therefore, be removed from quotation on
the Nasdaq. The common stock is currently registered under Section 12(g) of the
Exchange Act. Registration under the Exchange Act may be terminated upon
application of Amtran to the SEC if such securities are not listed on a national
securities exchange or quoted on Nasdaq and there are fewer than 300 record
holders of such securities. Termination of registration of our common stock
under the Exchange Act would mean certain provisions of the Exchange Act, such
as the short-swing trading provisions of Section 16(b), the requirement to file
periodic reports, the requirement of furnishing

                                       37

<Page>
a proxy statement in connection with shareholders' meetings pursuant to
Section 14(a) and the requirements of Rule 13e-3 under the Exchange Act with
respect to 'going private' transactions, would no longer be applicable to
Amtran. In addition, 'affiliates' of Amtran and persons holding 'restricted
securities' of Amtran might as a result be deprived of the ability to dispose of
such securities pursuant to Rule 144 promulgated under the Securities Act of
1933, as amended. It is the present intention of Mikelsons to seek to cause
Amtran to make an application for the termination of the registration of our
common stock under the Exchange Act as soon as practicable after the effective
time of the merger.

SOURCE AND AMOUNT OF FUNDS

    The total amount of funds required to pay the merger consideration, make
cash payments for canceled options and pay related fees and expenses is
approximately $87 million. The fees and expenses expected to be incurred in
connection with the merger are described in greater detail in 'Estimated Fees
and Expenses of the Merger'. In addition, we will purchase between 5 and 10% of
ILFC's shares of Series B preferred stock pursuant to the ILFC Agreement in
exchange for a note due January 15, 2002 with an annual interest rate of 7.38%.
Assuming that we purchase 5% of ILFC's shares of Series B preferred stock, the
aggregate principal amount of this note will be approximately $2.2 million.

    ATA has received a letter dated June 18, 2001 (the 'Commitment Letter'),
from Salomon Smith Barney and Citicorp with respect to a $175 million 3-year
reducing revolving credit facility (the 'Secured Credit Facility'). In this
letter, Citicorp committed to provide the Secured Credit Facility, subject to
terms and conditions set forth therein, including Citicorp's right to syndicate
the Secured Credit Facility. Salomon Smith Barney and Citicorp are affiliates of
each other. On June 18, 2001, Bank One, NA agreed to commit $87.5 million of the
$175 million Secured Credit Facility, act as administrative agent and take an
active role, through its affiliate, Banc One Capital Markets, Inc., in the
syndication of the Secured Credit Facility. We expect that the structure of the
Secured Credit Facility will include both a term loan and a revolving credit
facility. We are in the process of negotiating the definitive documentation for
the Secured Credit Facility with the lenders.

    The Secured Credit Facility will be used to finance the acquisition of all
the outstanding public shares of our common stock other than those owned by
Mikelsons and INDUS, to pay related transaction fees and expenses, to purchase
rotables and to provide for the ongoing working capital needs and general
corporate purposes of Amtran and its subsidiaries. The amount available for the
acquisition of shares of our common stock shall not exceed $82.0 million in the
aggregate.


    The commitment under the Commitment Letter is conditioned upon, among other
things, (i) Citicorp not discovering or otherwise becoming aware of information
about Amtran that Citicorp reasonably believes to be materially inconsistent
with its understanding as of June 18, 2001 of Amtran and its business, (ii) the
preparation, execution and delivery of mutually acceptable loan documentation,
(iii) the absence of (a) any material adverse change in the business, condition
(financial or otherwise), operations or properties of Amtran and its
subsidiaries, taken as a whole, since December 31, 2000 and (b) any change in
market conditions that would impair the syndication of the Secured Credit
Facility, (iv) the accuracy and completeness in all material respects of
Amtran's representations and warranties in the Commitment Letter and of all
information furnished by Amtran to Citicorp and Salomon Smith Barney and
(v) the payment in full of all fees, expenses and other amounts payable under
the Commitment Letter.


    The execution of the Secured Credit Facility is conditioned upon, among
other things, customary conditions for facilities of this nature, including
(i) the preparation, execution and delivery of mutually acceptable loan
documentation, (ii) creation and perfection of liens granted over the collateral
for the Secured Credit Facility, (iii) the roll-over of equity options being
acceptable to Salomon Smith Barney, (iv) the completion of legal due diligence
in connection with the transactions, and due diligence with respect to the
collateral, (v) legal opinions from special New York counsel for each of ATA and
Amtran and a solvency opinion from an independent solvency evaluator
satisfactory to Salomon Smith Barney, (vi) the absence of a material adverse
change since December 31, 2000 in the business, financial condition or results
of operations of

                                       38

<Page>
Amtran and its subsidiaries, taken as a whole, (vii) evidence that as of the
closing date the funded lease-adjusted debt of Amtran and its subsidiaries is no
more than $955 million, (viii) evidence that as of closing date, Amtran's
minimum cash (or cash equivalents) on hand is no less than $85 million and
(ix) payment of accrued fees and expenses. Each advance under the Secured Credit
Facility is conditioned upon, among other things, the non-occurrence and
non-continuation of any unmatured event of default, the representations and
warranties contained in the loan agreement for the Secured Credit Facility being
true and correct in all material respects with the same effect as though such
representations and warranties had been made on the date of each advance, except
to the extent such representation and warranty relates to an earlier date (in
which case on and as of such earlier date) and compliance with the borrowing
base.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    The following discussion describes certain United States federal income tax
consequences of the merger. The discussion is based upon the Internal Revenue
Code of 1986, as amended (the 'Code'), existing and proposed treasury
regulations, rulings, administrative pronouncements and judicial decisions,
changes to which could materially affect the tax consequences described in this
proxy statement and could be made on a retroactive basis. This discussion does
not address all aspects of federal income taxation that may be important to you
based on your particular circumstances and does not address any aspect of state,
local or foreign tax laws. This summary assumes that shares of our common stock
are held as capital assets (generally, assets held for investment) at the time
of the merger and may not apply to holders who acquired shares of common stock
pursuant to the exercise of employee stock options or other compensation
arrangements with Amtran, holders that are subject to special tax treatment,
holders that hold shares of our common stock as part of a 'straddle', 'hedge',
or 'conversion transaction', holders the functional currency of which is not the
U.S. dollar or holders that are nonresident alien individuals or foreign
corporations, partnerships, trusts or estates. Holders that may be subject to
special tax treatment include broker-dealers, persons liable for alternative
minimum tax, traders that elect to use a marked-to-market method of accounting
for their securities holdings, insurance companies, tax-exempt organizations,
retirement plans, financial institutions and regulated investment companies.

    Consequences to Holders of Common Stock. A holder of shares of our common
stock will recognize gain or loss equal to the difference between the amount of
cash received in the merger and the holder's adjusted tax basis in the shares of
common stock surrendered. Such gain or loss will generally be capital gain or
loss and will be long-term capital gain or loss if at the effective time of the
merger the holder has a holding period for the common stock of more than one
year.

    Backup Withholding and Information Reporting. Payments of cash to a holder
surrendering shares of our common stock will be subject to information reporting
and 'backup' withholding on the cash payable to the holder, unless the holder
furnishes its social security or other taxpayer identification number and meets
certain other conditions. Corporations generally are exempt from backup
withholding. Any amounts withheld from payments to a holder under the backup
withholding rules generally will be allowed as a credit against the holder's
United States federal income tax liability, which may entitle such holder to a
refund provided the required information is furnished to the Internal Revenue
Service.

    The preceding discussion does not purport to be a complete analysis or
discussion of all potential tax effects relevant to the merger. Thus,
shareholders are urged to consult their own tax advisors as to the specific tax
consequences to them of the merger, including tax return reporting requirements,
the applicability and effect of federal, state, local, foreign and other
applicable tax laws and the effect of any proposed changes in the tax laws. The
merger will not result in any United States federal income tax consequences for
Amtran, Mikelsons or INDUS. The merger will be a taxable transaction for Messrs.
Tague, Wolff and Hlavacek and will result in the same United States federal
income tax consequences as described above for other holders of shares of our
common stock.

SHAREHOLDER LITIGATION RELATING TO THE MERGER

    Commencing on May 17, 2001, we, along with several of our officers and
directors have been named as defendants in two putative class actions filed in
the Superior Court of the State of Indiana in and for the County of Marion. The
plaintiffs allege that Mikelsons and the individual defendants have breached and
are breaching their fiduciary duties to the public shareholders of Amtran common
stock. The plaintiffs seek, among other things, declaratory and injunctive
relief, including: directing the individual defendants to exercise their duty of
care by giving consideration to any proposed business combination that would
maximize Amtran's shareholder value; directing the individual defendants to
adequately ensure that no conflicts of interest exist between the individual
defendants and their fiduciary obligation to maximize shareholder value or, if
such conflicts exist, to ensure that all conflicts are resolved in the best
interests of Amtran's public shareholders and awarding plaintiffs the costs and
disbursements of the action, including reasonable attorneys' and experts' fees.

    We, along with several of our officers and directors have also been named as
defendants in one putative class action filed in U.S. District Court in the
Southern District of Indiana, Indianapolis Division, based on a diversity claim.
The plaintiffs allege, among other things, that Mikelsons and each of the
individual defendants have violated the fiduciary duties they owe to the
shareholders of Amtran. The plaintiffs seek judgment, among other things, as
follows: declaring that defendants have breached their fiduciary duties to the
public shareholders of Amtran and aided and abetted such breaches; enjoining the
proposed sale to Mr. Mikelsons and, if the proposed sale is consummated,
rescinding it; awarding plaintiff and the class compensatory and/or rescissory
damages as allowed by law; and awarding interest, attorney's fees, expert fees
and other costs, in an amount to be determined.

    We have entered into a Memorandum of Understanding with each of the
plaintiffs (the 'Memorandum'), subject to the conditions therein and to court
approval, providing for the settlement of the lawsuits described above. We,
along with the named officers and directors, vigorously deny any liability
whatsoever in connection with the claims asserted in the actions. We, along with
the named officers and directors, entered into the Memorandum because it will
halt the substantial expense, inconvenience and distraction of continued
litigation of the plaintiffs' claims, and put to rest any and all the
plaintiffs' claims relating to the merger. The parties to the Memorandum agreed,
among other things, to attempt, in good faith, to agree upon and execute as soon
as practicable an appropriate stipulation of settlement, dismissing on the
merits and with prejudice all claims asserted in the complaints filed in the
state court actions, and to obtain final state court approval of the settlement,
and the release and dismissal of the state court actions with prejudice and to
voluntarily dismiss the federal court action. On July 25, 2001, the federal
court action was dismissed without prejudice. The settlement is subject to
confirmatory discovery. In the Memorandum, the defendants acknowledged that the
existence of these lawsuits was a factor in Mikelsons' decision to increase the
consideration he would pay per share and Mikelsons agreed that he took into
account the desirability of satisfactorily addressing the claims asserted in
these lawsuits in agreeing to increase the consideration he would pay. At the
time, Mikelsons was aware that the plaintiffs had stated they would be willing
to settle their claims, subject to court approval, if the consideration paid in
the proposed transaction was at least $23 per share. Amtran has agreed to pay an
aggregate of $285,000 in attorneys' fees, a portion of which has been requested
by Amtran to be paid under its directors' and officers' liability insurance
policy.

METHOD OF ACCOUNTING

    The merger will be accounted for under the purchase method of accounting as
a purchase of INDUS by Amtran. The merger will not result in a change in the
recorded basis of the assets held by Amtran immediately prior to the merger.

REGULATORY AND OTHER APPROVALS

    The only U.S. federal or state regulatory requirements applicable to the
merger and the ILFC amendment are the giving of notice of the merger to the U.S.
Department of Transportation and

                                       40

<Page>
the filing of articles of merger and articles of amendment with the Secretary of
State of Indiana. On August 7, 2001, we provided notice of the merger to the
U.S. Department of Transportation.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

Mikelsons and INDUS Ownership of Common Stock


    As of September 5, 2001, Mikelsons owned 8,271,200 shares of our common
stock (or approximately 72% of the outstanding shares of our common stock on
that date). Mikelsons acquired his shares in Amtran in 1984, in exchange for his
contribution of, among other things, all the outstanding shares of the common
stock of ATA. On June 18, 2001, Mikelsons and INDUS entered into a stock
subscription agreement (the 'Stock Subscription Agreement'), pursuant to which
Mikelsons will subscribe for and purchase, and INDUS will issue to Mikelsons,
8,271,200 shares of the common stock, without par value, of INDUS, in
consideration of the contribution by Mikelsons to INDUS of the 8,271,200 shares
of our common stock owned by him, subject to certain conditions. Satisfaction of
the shareholder approval condition to the merger is a condition to the
transactions contemplated by the Stock Subscription Agreement. Upon completion
of the merger, each issued and outstanding share of common stock of INDUS shall
be converted into and become one fully paid and nonassessable share of common
stock, without par value, of Amtran, the surviving corporation.


Ownership of Common Stock by Our Officers and Directors


    As of September 5, 2001, our executive officers and directors (other than
Mikelsons) beneficially owned an aggregate of 1,300,467 shares of our common
stock consisting of 84,762 shares of our common stock (which represented on that
date less than 1% of the outstanding shares and approximately 2.6% of the
outstanding shares not owned by Mikelsons or any Mikelsons Affiliate), presently
exercisable options to purchase 1,214,689 shares of our common stock (or
approximately 9.6% of the outstanding shares on such date assuming the exercise
of all such options) with an average exercise price of $11.20 per share and
1,010 shares of our common stock allocated to such directors and executive
officers under the ATA Employees' Salary Savings Plan. To our knowledge, all of
our executive officers and directors intend to vote the 85,772 shares of our
common stock which they have the power to direct the voting of in favor of the
merger.



    As of September 5, 2001, Mr. Tague beneficially owned 460,980 shares of our
common stock, including options to purchase 450,758 shares with an average
exercise price of $12.52 (which represented on that date approximately 3.9% of
the outstanding shares assuming the exercise of all such options). As of the
same date, Mr. Wolff beneficially owned 350,094 shares of our common stock,
including options to purchase 338,000 shares with an average exercise price of
$13.48 (which represented on that date approximately 3.1% of the outstanding
shares assuming the exercise of all such options). As of the same date, Mr.
Hlavacek beneficially owned 362,393 shares of our common stock, including
options to purchase 309,431 shares with an average exercise price of $13.86
(which represented on that date approximately 3.0% of the outstanding shares
assuming the exercise of all such options). Messrs. Tague, Wolff and Hlavacek
intend to vote all shares of our common stock which they have the power to
direct the voting of in favor of all items at the annual meeting.


Treatment of Restricted Stock

    Under the merger agreement, the restriction period for each restricted
share, whether vested or unvested, granted under any of our stock plans shall be
deemed to expire immediately prior to the closing of the merger, unless it
expired sooner in accordance with the restriction period set forth under the
terms of the stock plan, in which case, the restriction period shall expire in
accordance with the terms of the applicable stock plan.

                                       41

<Page>
Treatment of Stock Options


    All unvested stock options issued to our officers and certain stock options
issued to non-officers automatically vested upon the approval of the merger by
your board of directors. Your board of directors and the compensation committee
of your board of directors have adopted resolutions providing that all stock
options (other than those held by the 19 officers whose options will remain
outstanding following the merger as described below) that remain outstanding
immediately prior to the closing of the merger will be canceled in exchange for
a cash payment equal to the excess, if any, of $23 over the exercise price of
those options multiplied by the number of shares of our common stock covered by
those options, and that all outstanding stock options with an exercise price in
excess of $23 per share will be canceled without any cash payment. In the
aggregate, our employees (other than the 19 officers described in the following
paragraph) held as of September 4, 2001 options to purchase 520,015 shares of
our common stock with an average exercise price of $11.87 per share.


    We have entered into option modification agreements with 19 of our officers
(including Messrs. Tague, Wolff and Hlavacek) providing that these officers will
not exercise their options prior to the merger and that their stock options will
remain outstanding following the merger. Under these agreements, these officers
have agreed, among other things, to the modification of the terms of their
options as follows:

     not to exercise their options prior to (a) completion of the merger or (b)
     termination of the merger agreement in accordance with its terms;

     that their options will remain outstanding following the merger and be
     exercisable during annual 60-day exercise periods which begin on June 1 of
     each year;

     have the right to put shares acquired upon exercise of their options during
     an annual 60-day put period beginning 6 months after their exercise date in
     each year for five years beginning December 15, 2002; and

     the price per share at which officers will have the right to put shares
     will be determined by an annual valuation of Amtran by a third-party
     appraiser selected by the Amtran board of directors.

    The exercise prices of each of these options will remain the same following
the completion of the merger. These officers will not be permitted to exercise
their options unless certain conditions are met. The average exercise price of
these options is $11.31. These agreements also set forth procedures for the
treatment of these officers' options and shares upon resignation, termination of
employment and death. These modifications were made, in part, to provide
liquidity for these officers' options and shares so long as we are a private
company. If our common stock ever becomes publicly traded again, these exercise
limitations and put rights would expire. In the aggregate, these 19 officers
hold options covering 1,749,464 shares of common stock.

    In addition, we expect to increase the base salaries of the officers rolling
over their options, other than Messrs. Tague, Wolff, Hlavacek and McKnight, by
approximately 10% following completion of the merger. However, this increase
remains subject to approval by Mikelsons and the compensation committee of the
board of directors. This increase is intended to compensate for any decrease in
overall compensation for these officers resulting from the merger and the
rollover of their options. In the aggregate, this increase in base salary would
result in increased compensation expense of less than $300,000 per annum.

Indemnification of Officers and Directors

    The surviving corporation shall honor all of Amtran's obligations to
indemnify (including any obligations to advance funds for expenses) the current
or former directors and officers of Amtran for acts or omissions by such
directors or officers occurring prior to the effective time of the merger to the
extent that the obligations exist as of the date of the merger agreement,
whether pursuant to Amtran's charter, bylaws, individual indemnity agreements or
otherwise. Such

                                       42

<Page>
obligations shall survive the merger and shall continue in full force and effect
in accordance with their terms.

    The merger agreement further requires that, for a period of six years after
completion of the merger, the surviving corporation will maintain in effect the
current policies of directors' and officers' liability insurance on behalf of
our directors and officers that are currently covered by our existing directors'
and officers' liability insurance maintained by Amtran or policies of at least
the same coverage, with respect to claims arising from or related to facts or
events which occurred at or before the effective time of the merger, except that
the surviving corporation is not required to pay annual premium payments in
excess of 150% of the annual premiums paid as of the date of the merger
agreement.


    On August 31, 2001, Mikelsons and INDUS entered into agreements with each of
Messrs. Tague, Wolff and Hlavacek pursuant to which Mikelsons and INDUS will
indemnify Messrs. Tague, Wolff and Hlavacek against certain liabilities under
the Exchange Act arising by reason of the status of Messrs. Tague, Wolff and
Hlavacek as filing persons of the Schedule 13E-3 filed with respect to the
merger.


Proposed ILFC Amendment

    The discussion in this proxy statement of the principal terms of the ILFC
Amendment, which is attached as Exhibit A to the ILFC Agreement, and the ILFC
Agreement is qualified in its entirety by reference to the ILFC Agreement, a
copy of which is attached as Annex B to this proxy statement, and which is
incorporated in this proxy statement by reference. The following description
summarizes the material provisions of the ILFC Agreement. We urge you to read
the ILFC Agreement and the ILFC Amendment carefully.

    ILFC currently owns all 300 outstanding shares of our Series B preferred
stock, the original terms of which are set forth in the Purchase and Investor
Rights Agreement dated as of September 19, 2000, between ILFC and us, which is
filed as an exhibit to our annual report on Form 10-K/A for the fiscal year
ended December 31, 2000. On May 16, 2001, we entered into the ILFC Agreement
with ILFC to modify the terms of the Series B preferred stock in connection with
the merger. Under the ILFC Agreement, we have agreed to amend and restate
Article XII of our articles of incorporation as set forth in the ILFC Amendment
immediately before the merger becomes effective to modify the terms of the
Series B preferred stock to reflect the fact that following the merger, Amtran
will be a private company. As a result of the ILFC Amendment, ILFC's shares of
Series B preferred stock will become convertible at the conversion price of
$15.67 into shares of the common stock of the surviving corporation (rather than
being convertible into the right to receive $23 per share of common at the
conversion price of $15.67). Therefore, ILFC will, to the extent that it elects
to convert its shares of Series B preferred stock into shares of common stock of
the surviving corporation: (a) continue to benefit from increases in the value
of Amtran and (b) bear the risks of decreases in the value of Amtran.

    As part of the agreement, ILFC agreed not to convert its existing shares of
Series B preferred stock into common shares prior to the merger and to vote its
shares of Series B preferred stock in favor of the ILFC Amendment. We have
agreed to repurchase between 5 and 10% (with the amount to be determined by
Amtran) of ILFC's shares of Series B preferred stock at a price reflecting
merger consideration paid to holders of shares of our common stock. Assuming
that we purchase 5% of its shares of Series B preferred stock and that ILFC
converts all its remaining shares of Series B preferred stock following the
merger, ILFC would own approximately 1,818,762 shares of our common stock. Under
the ILFC Agreement, the conversion price of the Series B preferred stock into
the common stock remains unchanged. However, upon redemption or termination of
conversion rights, ILFC will receive an additional premium equal to the
difference between $23 and the conversion price, as it may be adjusted from time
to time. The dividend rate on the Series B preferred stock will also increase
upon the completion of the merger from an annual rate of 5.0% of the liquidation
amount to an annual rate of 5.66% of the liquidation amount on the date the
merger is completed. On the fourth anniversary of the completion date of

                                       43

<Page>
the merger, the dividend rate will increase to 6.5% per annum, provided that
from and after the date that a public offering is consummated, the dividend rate
will decrease to 5.0% per annum.


    The ILFC Agreement also provides that we will lease an additional Boeing
737-800 aircraft from ILFC beginning in 2004 upon completion of the merger. We
will also pay ILFC an annual fleet consulting fee of $100,000, for a period of 4
years, in exchange for ILFC's assistance in the management of our
buyer-furnished-equipment and advice with respect to fleet retirement and other
fleet management issues.


    Approval of the ILFC Amendment is a condition to the merger agreement and
merger. The ILFC Amendment, which is subject to the approval of the holders of
Series B preferred stock, was approved by your board of directors on June 18,
2001. ILFC, as the sole holder of shares of our Series B preferred stock, has
agreed to vote in favor of the ILFC Amendment and has granted an irrevocable
proxy to Kenneth K. Wolff and James W. Hlavacek to vote its shares of our
Series B preferred stock with regard to the ILFC Amendment.

Interests of Certain Directors

    Under the terms of the plan of merger and the merger agreement, the
directors and officers of Amtran at the time of the merger will be the directors
and officers of the surviving corporation. Therefore, all directors elected at
the annual meeting will continue as directors of the surviving corporation
following the merger. There are, however, no employment contracts or agreements
with our officers or directors currently in place or expected to be put in place
in connection with the merger.

    Mr. Abel, Chairman of the compensation committee, is a partner in the
accounting firm of Blue & Co., LLC, which has provided tax and accounting
services to Amtran, Betaco and Mikelsons since 1973. Blue & Co. billed Amtran
$28,310 for tax and accounting services provided to Betaco and Mikelsons in
2000. Mikelsons is the sole owner of Betaco. Blue & Co. billed Betaco $20,835
for tax and accounting services in 2000. Mikelsons has advised us that he
currently expects that Blue & Co. will continue to provide certain tax and
accounting services to Amtran, Betaco and Mikelsons following the merger.

    Mr. Rogers, Chairman of the audit committee, is a partner in the law firm of
Cravath, Swaine & Moore, which is acting as Mikelsons' legal advisor in this
transaction and has regularly provided legal services to Amtran in connection
with securities offerings since its initial public offering in 1993. Cravath is
expected to continue to represent Amtran in those offerings on a continuing
basis, including prior to the completion of the merger. Cravath billed Amtran
approximately $641,399 in fees and expenses for legal services rendered to
Amtran in 2000.

Amtran's Engagement of Salomon Smith Barney

    At Mikelsons' request, Amtran engaged Salomon Smith Barney to act as
financial advisor to Mikelsons and INDUS. Under the engagement letter between
Amtran and Salomon Smith Barney, Amtran will be obligated to pay an advisory fee
and expenses to Salomon Smith Barney only upon completion of the merger. In
connection with this engagement, Amtran entered into an indemnity letter
agreement with Salomon Smith Barney. Amtran is obligated to indemnify Salomon
Smith Barney in connection with its engagement as financial advisor regardless
of whether the merger is completed. Amtran's engagement of Salomon Smith Barney
was considered by the single member special independent director committee in
its evaluation of the merger.

                                  THE PARTIES

AMTRAN

    We are a corporation formed under the laws of the State of Indiana. We were
incorporated in 1984 as a holding company for ATA. We own ATA, the eleventh
largest passenger airline in the United States (based on passenger revenue
miles) and a leading provider of scheduled airline services in selected markets.
We, through our subsidiaries, are also the largest commercial charter

                                       44

<Page>
airline in the United States and the largest provider of passenger airline
services to the U.S. military, in each case based on 2000 revenues. For the year
ended December 31, 2000, the revenues of ATA consisted of 58.3% scheduled
service, 19.1% commercial charter service and 14.6% military charter service,
with the balance derived from related services. We expect to increase
substantially the portion of its revenues that is derived from scheduled service
and reduce its emphasis on commercial charter services.

will subscribe for and purchase, and INDUS will issue to Mikelsons, 8,271,200
shares of the common stock, without par value, of INDUS, in consideration of the
contribution by Mikelsons to INDUS of the 8,271,200 shares of our common stock
owned by him, subject to certain conditions. Upon completion of the merger, each
issued and outstanding share of capital stock of INDUS will be converted into
and become one fully paid and nonassessable share of common stock, without par

governs the merger.

THE MERGER

    The merger agreement provides that, on the terms and subject to the
conditions set forth in the merger agreement, INDUS will be merged with and into
Amtran in accordance with the applicable provisions of the IBCL. Following the
merger, the separate corporate existence of INDUS will cease, and Amtran will
continue as the surviving corporation. INDUS may assign its rights and
obligations under the merger agreement to any company directly or indirectly
wholly owned by Mikelsons.

WHAT YOU WILL RECEIVE IN THE MERGER

    When the merger is completed, by virtue of the merger and without any action
on the part of the holder of any shares of our capital stock, or any shares of
common stock of INDUS:

        (i) each share of our common stock owned by Amtran, Mikelsons, INDUS or
    any other affiliate of Mikelsons (other than persons deemed to be affiliates
    of Mikelsons by reason of their positions as officers or directors of Amtran
    (the 'Excluded Affiliates')) will no longer be outstanding and will be
    canceled and retired and no consideration will be delivered or deliverable
    in exchange for those shares;

                                       46

<Page>
        (ii) each share of our common stock owned by one of our subsidiaries
    will be converted into one fully paid and nonassessable share of common
    stock, without par value, of Amtran as the surviving corporation in the
    merger;

        (iii) each issued and outstanding share of capital stock of INDUS will
    be converted into one fully paid and nonassessable share of common stock,
    without par value, of Amtran, as the surviving corporation in the merger;

        (iv) each issued and outstanding share of our common stock, other than
    the shares described under (i), (ii) and (iii) above, will be converted into
    the right to receive, upon valid surrender of a share certificate which
    formerly represented that share of our common stock, $23 per share in cash,
    without interest; and

        (v) each issued and outstanding share of our Series A1 preferred stock
    and our Series B preferred stock will remain outstanding as preferred stock
    of Amtran, as the surviving corporation.

EFFECTIVE TIME OF THE MERGER

    The merger will become effective on the date on which articles of merger
(including a plan of merger approved by holders of shares of our common stock)
are duly filed with the office of the Secretary of State of the State of
Indiana, or a later date as agreed to by INDUS and Amtran in those articles of
merger.

PAYMENT FOR SHARES; PROCEDURES FOR SURRENDER OF CERTIFICATES

    Before the merger is completed, INDUS will appoint a bank or trust company
to act as paying agent for the payment of the merger consideration. Promptly
following completion of the merger, we will deposit with the paying agent funds
necessary to pay the merger consideration.

    After the completion of the merger, the paying agent will mail a letter of
transmittal, which will include instructions for the delivery of certificates
formerly representing shares of our common stock to the paying agent, to all
record holders of shares of our common stock as of the time of the completion of
the merger. The letter of transmittal will also describe the procedures for
electronic delivery of share certificates. Holders of shares of our common stock
at the time of the merger should use this letter of transmittal to send
certificates formerly representing shares of our common stock to the paying
agent. After surrendering certificates formerly representing shares of our
common stock to the paying agent for cancelation, together with a properly
completed letter of transmittal, holders of those surrendered certificates will
be entitled to receive a cash payment from us in an amount equal to the number
of shares formerly represented by the surrendered certificates multiplied by the
merger consideration of $23. Each surrendered certificate will be canceled.

    PLEASE DO NOT SEND ANY AMTRAN SHARE CERTIFICATES WITH YOUR YELLOW PROXY
CARD. YOU WILL RECEIVE A LETTER OF TRANSMITTAL TO SURRENDER YOUR SHARE
CERTIFICATES.

    If a transfer of ownership of shares of our common stock is not registered
in our stock transfer books, payment of merger consideration of $23 per share
may be made to a person other than the person in whose name the surrendered
certificate is registered if

     the share certificate is properly endorsed or otherwise in proper form for
     transfer, and

     the person requesting payment pays any transfer or other taxes resulting
     from the payment of merger consideration to a person other than the
     registered holder of that certificate or establishes to our satisfaction
     that any such taxes have been paid or are not applicable.

    All cash paid upon the surrender of certificates formerly representing
shares of our common stock in accordance with the merger agreement will be
deemed to have been paid in full satisfaction of all rights pertaining to the
shares of our common stock so surrendered. After the completion of the merger,
no transfers of shares of our common stock that were outstanding at the time of
the merger will be made on our stock transfer books.

                                       47

<Page>
    If your Amtran share certificates have been lost, stolen or destroyed, you
will be entitled to obtain payment only by signing an affidavit to that effect
and, to the extent required by us posting a bond in an amount sufficient to
protect us against claims by any other party related to your share certificates.

TREATMENT OF STOCK OPTIONS

    Except for stock options held by our officers who enter into option
modification agreements purchase common stock of the surviving corporation in
the merger (described above under 'Special Factors -- Interests of Certain
Persons in the Merger -- Treatment of Stock Options'), (a) each option to
purchase shares of our common stock outstanding immediately prior to the
completion of the merger, whether vested or unvested, will be converted into the
right to receive the excess, if any, of $23 over the exercise price per share of
the stock option multiplied by the number of shares of our common stock subject
to the stock option, (b) all other rights to purchase shares of our common
stock, whether vested or unvested, will be converted into the right to receive
an amount of cash equal to the number of shares of common stock subject to the
stock right outstanding immediately prior to the completion of the merger
multiplied by $23 and (c) all options with an exercise price in excess of $23
per share will be canceled by action of our board of directors or the
compensation committee of our board. All amounts payable are subject to
applicable withholding taxes.

                agreement (excluding any breach by us without the consent of the
                single member special independent director committee),

           (ii) if any governmental entity issues an order, decree or ruling or
                takes any other action permanently enjoining, restraining or

     agreement and the date on which the merger closes (other than

     in which case the representations or warranties were not true and correct
     as of such date) or we have failed to perform in any material respect any
     of our obligations contained in the merger agreement, which breach cannot
     be or has not been cured by us within 30 days of notice to us of the breach
     (provided that INDUS is not then in material breach of any representation,
     warranty or covenant contained in the merger agreement); excluding,
     however, breaches and failures to perform by us relating to matters for
     which the consent or recommendation of the single member special

     of its representations and warranties in the merger agreement which is
     qualified as to materiality is not true and correct, as of the date of the

     (provided that we are not then in material breach of any representation,
     warranty or covenant contained in the merger agreement); and

     by INDUS, if our board of directors or the single member special
     independent director committee withdraws or modifies, or publicly proposes
     to withdraw or modify, in a manner adverse to INDUS, their respective
     approvals or recommendations of the merger, the plan of merger, the merger
     agreement and the ILFC Amendment.

    In the event of a termination, except as specifically provided in the merger
agreement, the merger agreement will become void and will have no effect,
without any liability or obligation on our part or on the part of INDUS, except
to the extent that the termination results from the material breach by a party
of any representation, warranty or covenant contained in the merger agreement.

AMENDMENT; WAIVER

time before or after receipt of the approval of the plan of merger by our
shareholders; provided that an amendment may not be

                                       53

<Page>
made after the approval of the plan of merger by our shareholders without the
further approval of our shareholders, if such amendment requires further
shareholders' approval under applicable law.

    In addition, at any time prior to completion of the merger, we and INDUS may

     extend the time for the performance of any of the obligations or other acts
     of the other parties,

     waive any inaccuracies in the representations and warranties contained in
     the merger agreement or in any document delivered pursuant to the merger
     agreement and

     subject to the requirements of applicable law and the provisions of the
     preceding paragraph, waive compliance with any of the agreements or
     conditions contained in the merger agreement.

special independent director committee and, if required by applicable law,
shareholder approval.

(1) The 'book value per common share' represents total shareholders' equity
    divided by average common shares outstanding.

(2) The 'ratio of earnings to fixed charges' represents earnings divided by
    fixed charges as defined in the following paragraph. The 'deficiency'
    represents the amount of fixed charges in excess of earnings.

    For purposes of these computations, earnings consist of income (loss) before
    income taxes, plus fixed charges, adjusted to exclude the amount of any
    interest capitalized during the period. Fixed charges include the total of:
    (a) interest, whether expensed or capitalized; (b) amortization of debt
    expense relating to any indebtedness, whether expensed or capitalized; and
    (c) such portion of rental expense as can be demonstrated to be
    representative of the interest factor.

GENERAL

    Nominees for re-election this year are J. George Mikelsons, John P. Tague,

serve if elected.


    Our bylaws provide that the nominees for director receiving a plurality of
the votes cast at the Annual Meeting, up to the number of directors to be
elected at the Annual Meeting, will be elected. Your board of directors
recommends a vote 'FOR' these nominees. Abstentions and broker non-votes are not
included in the tabulation of votes cast and, therefore, do not have the effect
of votes in opposition to a nominee.

committee are 'independent directors' as defined by Rule 4200(a)(14) of the
National Association of Securities Dealers' listing standards, as applicable and
as may be modified. Additional information about the audit committee is set
forth in the 'Report of the Audit Committee' included in this proxy statement.
We do not have a standing nominating committee.

Compensation of Directors

    We do not pay directors who are also officers of Amtran additional
compensation for their service as directors. In 2000, non-employee directors
received the following:

     An annual retainer of $18,000 for serving on the Board

     An annual fee of $2,500 for serving as Chairman of a committee

     A fee of $2,000 for each board of directors meeting attended in person

     A fee of $1,000 for each committee meeting attended in person. (Amtran also
     pays its non-employee directors if they participate in board and committee
     meetings by telephone.)

     Options to purchase shares of Amtran's common stock pursuant to the Amtran,
     Inc. Stock Option Plan for Non-Employee Directors (a one-time grant of an
     option to purchase 2,000 shares following his election or appointment to
     the board of directors, and for as long as he remains an Eligible Director,
     an annual grant of an option to purchase 500 shares on the 30th day
     following each annual meeting of shareholders.)

Section 16(a) Beneficial Ownership Reporting Compliance

    Section 16(a) of the Exchange Act requires our directors and executive
officers and persons who own more than ten percent of Amtran's shares to file
with the SEC and Nasdaq reports on their ownership of shares of Amtran
(so-called 16(a) forms). Except as set forth below, we believe, based solely on
our review of copies of such reports, that our directors and officers complied
with all such filing requirements.

    On January 24, 2000, Willie G. McKnight, Jr. became the Executive Vice
President for Marketing and Sales of Amtran. The Form 3 filed with the SEC
reporting this event, which was required to be filed by February 3, 2000, was
filed late on February 22, 2000.

    During February 2000, John Tague sold shares of Amtran common stock in 4
transactions. The Form 4 filed with the SEC reporting these events, which was
required to be filed by March 10, 2000, was filed late on April 18, 2000.

    In 2000, Messrs. Tague, Wolff, Hlavacek, McKnight, Abel, Rogers and
Stipnieks each voluntarily reported the receipt of option grants on Form 4s
which, in each case, were filed with the SEC after the due date for the
reporting of such transactions on Form 4 but prior to the due date for reporting
these exempt transactions on Form 5. Accordingly, Amtran does not regard these
filings on Form 4 as late.

Certain Relationships and Related Party Transactions in 2000

    Mr. Mikelsons is the sole owner of Betaco, Inc., a Delaware corporation
('Betaco'). Betaco currently owns two airplanes (a Cessna Citation II and a Lear
Jet) and three helicopters (a Bell 206B Jet Ranger III, an Aerospatiale 355F2
Twin Star and a Bell 206L-3 LongRanger). The two airplanes and the Twin Star and
Jet Ranger III helicopters are leased or subleased to ATA. The LongRanger
helicopter is leased to American Trans Air ExecuJet, Inc. ('ExecuJet'). We
believe that the current terms of the leases and subleases with Betaco for this
equipment are no less favorable to us than those that could be obtained from
third parties.

    The sublease for the Cessna Citation currently requires a monthly payment of
$37,500 for a term beginning July 25, 1999 and ending July 24, 2004. The
sublease for the Lear Jet requires a monthly payment of $42,000 for a term
beginning December 24, 1999 and ending December 23, 2001. The lease for the
JetRanger III currently requires a monthly payment of $7,000 for a term
beginning June 15, 1993 and ending June 14, 2004. The sublease for the
Aerospatiale 355F2 Twin

                                       59

<Page>
Star requires a monthly payment of $12,000 for a term beginning January 1, 2000
and ending December 31, 2001, and the lease for the LongRanger requires a
monthly payment of $11,200 for a term beginning December 11, 1999 and ending
December 10, 2001.

    Betaco and Mr. Hlavacek own 100% of the interest in Delta Aviation LLC, an
Indiana limited liability corporation. Delta Aviation owns a Beech A36 Bonanza
aircraft. The aircraft is leased to ExecuJet and subleased to ATA for $75.00 per
flight hour for a term beginning December 11, 1998 and ending December 10, 2002.
No minimum monthly payment is required.

    Mr. Rogers, Chairman of the audit committee, is a partner in the law firm of
Cravath, Swaine & Moore, which provided legal services to Amtran in 2000. Mr.
Abel, Chairman of the compensation committee, is a partner in the accounting
firm of Blue & Co., which provided tax and accounting services to Amtran in
2000. See 'Special Factors -- Interests of Certain Persons in the
Merger -- Interests of Certain Directors'.

    As part of our compensation package to Willie McKnight, our executive Vice
President, Marketing and Sales, on January 24, 2000, we provided Mr. McKnight
with an interest-free loan of $230,000. The loan is evidenced by a Demand
Promissory Note signed by Mr. McKnight. However, 50% of the loan was forgiven on
January 24, 2001, and the remainder of the principal balance shall be forgiven
if Mr. McKnight is still employed by us on January 24, 2002. As of June 18,
2001, Mr. Mikelsons has outstanding indebtedness to Amtran with an aggregate
principal balance of $378,406. Amtran does not charge Mikelsons interest on this
indebtedness. In addition, we loaned Mr. Tague $175,000 on February 1, 2001. The
loan is evidenced by a Promissory Note, bears interest at an annual rate of 8%
and must be repaid by no later than January 31, 2002.

                    EXECUTIVE COMPENSATION AND STOCK OPTIONS

Report of Compensation Committee on Executive Compensation

WHAT IS OUR COMPENSATION PHILOSOPHY?

    The objectives of our executive compensation programs are to: (i) attract
and retain talented and experienced executives with compensation that is
competitive with other U.S. airlines of a size comparable to ATA and (ii) reward
outstanding performance and provide incentives based on individual and corporate
performance. In addition, during the time that our stock has been publicly
traded we have used restricted stock and stock options to align the interests of
management with those of the shareholders.

    The compensation committee is responsible for administering our compensation
policies and programs, including its officer incentive compensation programs.
The compensation committee currently consists of two independent non-employee
directors, Robert A. Abel and Andrejs P. Stipnieks. Mr. Abel, Chairman of the
compensation committee, is a director in the accounting firm of Blue & Co., LLC.
Mr. Abel's firm provided tax and accounting service to us in 2000. See 'Special
Factors -- Interests of Certain Persons in the Merger -- Interests of Certain
Directors'.

    As discussed below, the elements of compensation used by us include salaries
and short-term and long-term incentive programs, including the award of cash
bonuses and stock, while we have been a public company, options.

    If the merger is completed so that our common stock is no longer publicly
traded, we will re-evaluate the components of compensation.

HOW DO WE DETERMINE BASE PAY?

    The base pay for Mr. Mikelsons and Mr. Tague reflects Amtran's objective to
maintain salary levels that are competitive with those offered by U.S. airlines
of a size comparable to ATA for comparable positions, taking into consideration
a number of factors, as described below.

                                       60

<Page>
MR. MIKELSONS' 2000 BASE PAY

    In establishing a base salary for Mr. Mikelsons, the compensation committee
considered:

     a compensation analysis prepared by an independent consultant.

     the fact that Mr. Mikelsons would not participate in any equity-based
     incentive compensation plan or incentive cash bonus of Amtran and the fact
     that no increase in base salary over 1997 was being proposed.

     his age, experience and responsibilities.

    Each of these listed factors was evaluated by the compensation committee on
a subjective basis, and no particular weighting was given to any particular
factor. The compensation committee also sought to maintain the same relative
relationship between the salary levels of different officers as exists for
comparable positions at other U.S. airlines. After considering the above
factors, the compensation committee approved a base salary for the Chairman for
2000 of $688,194. Based on a compensation analysis available to the compensation
committee, such base salary is higher than the base salaries paid by other
airlines to executives holding comparable positions but, given the absence of
any stock-based compensation or incentive cash bonus, total compensation was
between the median and the 75th percentile of total annual cash compensation
paid by the other airlines included in the analysis.

MR. TAGUE'S 2000 BASE PAY

    In establishing a base salary for Mr. Tague, the compensation committee
considered:

     a compensation analysis prepared by an independent consultant.

     his age, experience and responsibilities.

    Each of these listed factors was evaluated by the compensation committee on
a subjective basis, and no particular weighting was given to any particular
factor. The compensation committee also sought to maintain the same relative
relationship between the salary levels of different officers as exists for
comparable positions at other U.S. airlines. After considering the above
factors, the compensation committee approved an annual base salary for 2000 for
Mr. Tague of $525,000. Based on a compensation analysis available to the
compensation committee, such base salary is between the median and the 75th
percentile of the base salary paid by most other airlines to executives holding
comparable positions. Mr. Tague's total compensation, including bonus and long-
term incentive compensation, is below the median of the annual compensation paid
by the other airlines included in the analysis.

HOW ARE ANNUAL BONUSES DETERMINED?

    Annual bonuses are paid in cash in the year following performance, based on
achievement of predetermined corporate goals. As in prior years, Mr. Mikelsons
was not eligible for a bonus payment in 2000. Because we did not achieve our
corporate goals in 2000, Mr. Tague did not receive a bonus for 2000.

PENSION PLANS

    We have no pension plans.

401(k) PLAN


    Under the American Trans Air, Inc. Employees' Salary Savings Plan (the
'401(k) Plan'), adopted on October 1, 1985, eligible employees could elect to
defer up to 15% of their salary into


                                       64

<Page>

the 401(k) Plan, not to exceed statutory limits. Generally, all employees
meeting a minimum-hours requirement are eligible to participate in the 401(k)
Plan. We have the discretion to make matching contributions to the 401(k) Plan
on behalf of participants who have made salary reduction contributions under the
Plan. In 2000, we contributed $.50 for each dollar contributed to the Plan by
eligible participants, up to 6% of their compensation. An employee stock
ownership feature was added to the 401(k) Plan in May 1993; however, this
feature will be eliminated upon completion of the merger. The ATA Employee Stock
Ownership Plan ('ESOP') has been a mechanism for us to award shares of our stock
for years in which profits have occurred. Addition of this benefit has permitted
eligible employees to become shareholders of Amtran and share in its potential
future growth and profitability. Generally, the eligibility requirements for the
ESOP have been identical to those of the 401(k) Plan, except an employee may
have been eligible for an ESOP contribution of Company stock even if the
employee did not elect pre-tax 401(k) Plan contributions.


    In those years in which we have experienced profits and chosen to make an
ESOP contribution, the 401(k) Plan accounts of eligible employees have been
credited with full and/or fractional shares of Company stock. Shares were
allocated based on compensation. In 2000, no shares of Amtran stock were
allocated to 401(k) Plan participant accounts.

              RATIFICATION OF THE SELECTION OF ERNST & YOUNG, LLP
                           AS INDEPENDENT ACCOUNTANTS

General

    Ernst & Young, LLP has been our independent public accountants for the past
eight years. The audit committee and the board believe that Ernst & Young's
long-term knowledge of Amtran is invaluable. Representatives of Ernst & Young
have direct access to members of the audit committee and regularly attend their
meetings. Representatives of Ernst & Young will attend the annual meeting to
answer any shareholder questions and to make a statement if they desire to do
so.

Audit Fees

    The aggregate fees billed by Ernst & Young for professional services
rendered for the audit of Amtran's annual financial statements for the year
ended December 31, 2000, and the reviews of the financial statements included in
Amtran's quarterly reports on Form 10-Q during the year 2000 were $273,500.

Financial Information Systems Design and Implementation Fees

    Ernst & Young performed no services for Amtran in 2000 related to financial
information systems design and implementation.

Other Fees

    The aggregate fees billed by Ernst & Young for services they rendered in the
year 2000 other than services included under the heading 'Audit Fees' were
$282,790.

    In 2000, the audit committee: (1) reviewed all services provided by Ernst &
Young to insure that they were within the scope previously approved by the
Committee; and (2) concluded that the non-audit services performed by Ernst &
Young for Amtran and its subsidiaries did not impair its independence as
Amtran's accountants. The Report of the Audit Committee contained in this proxy
statement contains additional information on Ernst & Young's services for
Amtran.

    We need a majority of the votes cast in person or by proxy and entitled to
vote at the annual meeting in order to ratify the selection of Ernst & Young as
independent accountants for 2001. The audit committee and the board of directors
recommend a vote 'FOR' Ernst & Young as independent accountants for 2001.

    Abstentions and broker non-votes are not included in the tabulation of votes
cast and, therefore, do not have the effect of votes in opposition to the
ratification of the selection of Ernst & Young as auditors.

Other Matters

    The Board of Directors does not anticipate that any other matters will be
properly brought before the Annual Meeting. However, if any other matters are
properly brought before the Annual Meeting, the persons named on the enclosed
proxy card will have discretionary authority to vote on those matters according
to their best judgment.

Report of the Audit Committee

    The audit committee has reviewed and discussed Amtran's audited financial
statements for the fiscal year 2000 with management and has received the written
disclosures and the letter from Ernst & Young, Amtran's independent auditors,
required by Independence Standards Board Standard No. 1 (Independent Discussions
with Audit Committee). The audit committee has also discussed with Ernst & Young
Amtran's audited financial statements for the fiscal year 2000, including, among
other things, the quality of Amtran's accounting principles, the methodologies
and accounting principles applied to significant transactions, the underlying
processes and estimates used

                                       66

<Page>
by management in its financial statements and the basis for the auditor's
conclusions regarding the reasonableness of those estimates, and the auditor's
independence, as well as the other matters required by Statement on Auditing
Standards No. 61 of the Auditing Standards Board of the American Institute of
Certified Public Accountants.

    Based on the review and discussions referred to above, the audit committee
recommended inclusion of the audited financial statements in Amtran's annual
report on Form 10-K to the board of directors.

    date of this proxy statement. INDUS and Mikelsons have entered into a Stock
    Subscription Agreement providing for the acquisition of these shares by
    INDUS. Therefore, INDUS may be deemed to be the beneficial owner of these
    shares.

(5) Dimensional Fund Advisors Inc. ('Dimensional'), an investment advisor
    registered under Section 203 of the Investment Advisors Act of 1940,
    furnishes investment advice to four investment companies registered under
    the Investment Company Act of 1940, and serves as investment manager to
    certain other investment vehicles, including commingled group trusts. (These
    investment companies and investment vehicles are the 'Portfolios'.) In its
    role as investment advisor and investment manager, Dimensional possesses
    both voting and investment power over the securities of Amtran that are
    owned by the Portfolios. Such securities are owned by the Portfolios, and
    Dimensional disclaims beneficial ownership of such securities.

(6) Group consists of seven persons (Messrs. Tague, Hlavacek, Wolff, Abel,
    Rogers, Stipnieks and McKnight).

                 SHAREHOLDER PROPOSALS FOR NEXT ANNUAL MEETING

    Upon the consummation of the merger, all of the outstanding shares of our
common stock will be held and voted by Mikelsons. As a result, we will not
solicit proxies in connection with the next annual meeting of shareholders. If
the merger is not consummated, then, according to the rules of the SEC, all
proposals of shareholders to be presented at the annual meeting would be
required to be received by the Secretary of Amtran a reasonable time before we
begin to print and mail our proxy materials. These proposals would also need to
comply with the rules of the SEC governing the form and content of proposals in
order to be included in our proxy statement and form of proxy.

    Shareholder proposals and related notices should be sent to Brian T. Hunt,
Secretary, 7337 West Washington Street, Indianapolis, Indiana 46231.

                                 OTHER MATTERS

    We know of no other business to be presented at the annual meeting. If other
matters do properly come before the annual meeting, or any adjournment or
postponement thereof, it is the intention of the persons named in the proxy to
vote on such matters according to their best judgment unless the authority to do
so is withheld in such proxy.

        AGREEMENT AND PLAN OF MERGER dated as of June 18, 2001, between INDUS
    ACQUISITION COMPANY, an Indiana corporation ('SUB'), and AMTRAN, INC., an
    Indiana corporation (the 'COMPANY').

    WHEREAS, as of the date hereof, J. George Mikelsons ('JGM') owns 8,271,200
shares of the common stock, without par value, of the Company (the 'COMPANY
COMMON STOCK');

    WHEREAS the respective Boards of Directors of Sub and the Company have
approved the merger (the 'MERGER') of Sub into the Company, on the terms and
subject to the conditions set forth in this Agreement, whereby (a) each issued
share of Company Common Stock not owned by JGM, Sub or the Company, shall be
converted into the right to receive from the Surviving Corporation $23.00 in
cash, without interest, and (b) each issued share of Series A1 Preferred Stock,
without par value, of the Company (the 'SERIES A1 PREFERRED STOCK') and Series B
Preferred Stock, without par value, of the Company (the 'SERIES B PREFERRED
STOCK' and, together with the Series A1 Preferred Stock, the 'COMPANY PREFERRED
STOCK', and the Company Preferred Stock, together with the Company Common Stock,
the 'COMPANY CAPITAL STOCK'), shall remain outstanding;

    WHEREAS the Company has entered into a Purchase and Voting Agreement dated
as of May 16, 2001 (the 'ILFC AGREEMENT' and, together with this Agreement, the
'TRANSACTION AGREEMENTS'), with International Lease Finance Corporation, a
California corporation ('ILFC'), and which was approved by the Board of
Directors of the Company (the 'COMPANY BOARD') on the date hereof pursuant to
which (i) the Company will amend Article XII (the 'ILFC AMENDMENT') of the
Company Charter (as defined in Section 3.02), subject to receipt of the
requisite shareholder approval, immediately prior to the Effective Time (as
defined in Section 1.03) to modify certain terms of the Series B Preferred Stock
to reflect the fact that following the Merger the Company will be private, (ii)
ILFC has agreed to vote its shares of Series B Preferred Stock in favor of the
ILFC Amendment and (iii) the Company has agreed to repurchase between 5 and 10%
of ILFC's shares of Series B Preferred Stock, with the amount to be repurchased
to be determined by the Company; and

    WHEREAS Sub and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the Merger and also to
prescribe various conditions to the Merger.

    NOW, THEREFORE, the parties hereto agree as follows:

                                   ARTICLE I
                                   THE MERGER

    SECTION 1.01. The Merger. On the terms and subject to the conditions set

    SECTION 1.02. Closing. The closing (the 'CLOSING') of the Merger shall take
place at the offices of Cravath, Swaine & Moore, 825 Eighth Avenue, New York,
New York 10019 at 10:00 a.m. on the second business day following the
satisfaction (or, to the extent permitted by Law (as defined in Section
3.04(a)), waiver by all parties) of the conditions set forth in Section 7.01,
or, if on such day any condition set forth in Section 7.02 or 7.03 has not been
satisfied (or, to the extent permitted by Law, waived by the party or parties
entitled to the benefits thereof), as soon as practicable after all the
conditions set forth in Article VII have been satisfied (or, to the extent
permitted by Law, waived by the parties entitled to the benefits thereof), or at
such other place, time and date as shall be agreed in writing between Sub and
the Company. The date on which the Closing occurs is referred to in this
Agreement as the 'CLOSING DATE'.

    SECTION 1.03. Effective Time. Prior to the Closing, the Company shall
prepare, and on the Closing Date or as soon as practicable thereafter the
Company shall file with the office of the Secretary of State of the State of
Indiana, articles of merger, including the plan of merger contained in
Exhibit A (the 'PLAN OF MERGER'), or other appropriate documents (in any such
case, the 'ARTICLES OF MERGER') executed in accordance with the relevant

                                      A-1

<Page>
recordings required under the IBCL. The Merger shall become effective at such
time as the Articles of Merger are duly filed with such Secretary of State, or
at such other time as Sub and the Company shall agree and specify in the
Articles of Merger (the time the Merger becomes effective being the 'EFFECTIVE
TIME').

    SECTION 1.04. Effects. The Merger shall have the effects set forth in
Section 40-6 of the IBCL.

    SECTION 1.05. Articles of Incorporation and Bylaws. (a) The Articles of
Incorporation of the Company as in effect immediately prior to Effective Time,
as amended by the ILFC Amendment, shall be the Articles of Incorporation of the
Surviving Corporation until thereafter changed or amended as provided therein or
by applicable Law.

    (b) The Bylaws of the Company as in effect immediately prior to the
Effective Time shall be the Bylaws of the Surviving Corporation until thereafter
changed or amended as provided therein or by applicable Law.

    SECTION 1.06. Directors. The directors of the Company immediately prior to
the Effective Time shall be the directors of the Surviving Corporation, until
the earlier of their resignation or removal or until their respective successors
are duly elected and qualified, as the case may be.

    SECTION 1.07. Officers. The officers of the Company immediately prior to the
Effective Time shall be the officers of the Surviving Corporation, until the
earlier of their resignation or removal or until their respective successors are

                                   ARTICLE II
                       EFFECT ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

    SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of
the Merger and without any action on the part of the holder of any shares of
Company Capital Stock or any shares of capital stock of Sub:

        (a) Capital Stock of Sub. Each issued and outstanding share of capital
    stock of Sub shall be converted into and become one fully paid and
    nonassessable share of common stock, without par value, of the Surviving
    Corporation.

        (b) Cancelation of Treasury, JGM-Owned and Sub-Owned Stock. Each share
    of Company Common Stock that is owned by the Company, JGM, Sub or any other
    affiliate of JGM (other than any person who is deemed to be an affiliate of
    JGM by reason of such person's position as an officer or director of the
    Company (collectively, the 'EXCLUDED AFFILIATES')) shall no longer be
    outstanding and shall automatically be canceled and retired and shall cease
    to exist, and no consideration shall be delivered or deliverable in exchange
    therefor. Each share of Company Common Stock that is owned by any subsidiary
    of the Company shall automatically be converted into one fully paid and
    nonassessable share of common stock, without par value, of the Surviving
    Corporation.

        (c) Conversion of Company Capital Stock. (1) Subject to
    Section 2.01(b), each issued share of Company Common Stock shall be
    converted into the right to receive from the Surviving Corporation $23.00 in
    cash, without interest.

        (2) Each issued share of Company Preferred Stock shall remain
    outstanding.

        (3) The cash payable upon the conversion of shares of Company Common
    Stock pursuant to this Section 2.01(c) is referred to collectively as the
    'MERGER CONSIDERATION'. At the Effective Time, all such shares of Company
    Common Stock shall no longer be outstanding and shall automatically be
    canceled and retired and shall cease to exist, and each holder of a
    certificate that immediately prior to the Effective Time represented any
    such shares of Company Common Stock (each, a 'CERTIFICATE') shall cease to
    have any rights with respect thereto, except the right to receive Merger
    Consideration upon surrender of a Certificate in accordance with
    Section 2.02, without interest.

    SECTION 2.02. Exchange of Certificates. (a) Paying Agent. Prior to the
Effective Time, Sub shall designate a bank or trust company to act as paying
agent (the 'PAYING AGENT') for the payment of the

                                      A-2

<Page>
Merger Consideration upon surrender of Certificates. Promptly following the
Effective Time, the Surviving Corporation shall provide to the Paying Agent cash
in an amount sufficient to pay for the shares of Company Common Stock converted
into the right to receive cash pursuant to Section 2.01(c) (such cash being
hereinafter referred to as the 'EXCHANGE FUND'). All of the fees and expenses of
the Paying Agent shall be borne by the Surviving Corporation.

    (b) Exchange Procedure. The Surviving Corporation shall cause the Paying
Agent to mail promptly after the Effective Time (but, in any event, within five
days after the Effective Time) to each holder of record of Certificates, (i) a
form of letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to Certificates shall pass, only upon
delivery of Certificates to the Paying Agent and shall be in such form and have
such other provisions as the Surviving Corporation may reasonably specify) and
(ii) instructions for use in effecting the surrender of Certificates in exchange
for Merger Consideration. Upon surrender of a Certificate for cancelation to the
Paying Agent, together with such letter of transmittal, duly completed and
validly executed, and such other documents as may reasonably be required by the
Paying Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor the amount of cash into which the shares of Company Common
Stock theretofore represented by such Certificate shall have been converted
pursuant to Section 2.01(c), and the Certificate so surrendered shall forthwith
be canceled; the Surviving Corporation shall enter into a paying agency
agreement with the Paying Agent which provides that the Paying Agent shall
promptly following any such surrender of Certificates (but, in any event, within
three business days after the Paying Agent receives such Certificates) dispatch
by mail payment of such amount to such holder. In the event of a transfer of
ownership of Company Common Stock that is not registered in the transfer records
of the Company, payment may be made to a person other than the person in whose
name the Certificate so surrendered is registered, if such Certificate shall be
properly endorsed or otherwise be in proper form for transfer and the person
requesting such payment shall pay any transfer or other taxes required by reason
of the payment to a person other than the registered holder of such Certificate
or establish to the satisfaction of the Surviving Corporation that such tax has
been paid or is not applicable. Until surrendered as contemplated by this
Section 2.02, each Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the amount of
cash, without interest, into which the shares of Company Common Stock
theretofore represented by such Certificate have been converted pursuant to
Section 2.01(c). No interest shall be paid or shall accrue on the cash payable
upon surrender of any Certificate.

    (c) No Further Ownership Rights in Company Common Stock. The Merger
Consideration paid upon surrender of a Certificate in accordance with the terms
of this Article II shall be deemed to have been paid in full satisfaction of all
rights pertaining to the shares of Company Common Stock formerly represented by
such Certificate, and after the Effective Time there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of shares of Company Common Stock that were outstanding immediately
prior to the Effective Time. If, after the Effective Time, any Certificates are
presented to the Surviving Corporation or the Paying Agent for any reason, they
shall be canceled and exchanged for the amount of cash into which the shares of
Company Common Stock theretofore represented by such Certificates shall have
been converted as provided in this Article II.

    (d) No Liability. None of Sub, the Company or the Paying Agent shall be
liable to any person in respect of any cash from the Exchange Fund that is
required under applicable Law to be delivered to a public official pursuant to
any applicable abandoned property, escheat or similar Law.

    (e) Investment of Exchange Fund. The Surviving Corporation shall direct the
Paying Agent to invest any cash included in the Exchange Fund, as directed by
the Surviving Corporation, on a daily basis. Any interest and other income
resulting from such investments shall be paid to the Surviving Corporation.

    (f) Withholding Rights. The Surviving Corporation shall be entitled to
deduct and withhold, as required by applicable Law, any applicable taxes from
the consideration otherwise payable to any holder of Company Common Stock
pursuant to this Agreement.

    (g) Lost, Stolen or Destroyed Certificates. In the event any Certificate
shall have been lost, stolen or destroyed, the holder of such lost, stolen or
destroyed Certificate shall execute an affidavit of that fact upon request. The
holder of any such lost, stolen or destroyed Certificate shall also deliver a
reasonable

                                      A-3

<Page>
indemnity against any claim that may be made against the Surviving Corporation
or the Paying Agent with respect to the Certificate alleged to have been lost,
stolen or destroyed. The affidavit and any indemnity which may be required
hereunder shall be delivered to the Paying Agent, who shall be responsible for
making payment for such lost, stolen or destroyed Certificate pursuant to the
terms hereof.

    (h) Adjustment to Prevent Dilution. In the event that following the date
hereof and prior to the Effective Time the Company changes the number of shares
of Company Common Stock or securities convertible or exchangeable into or
exercisable for shares of Company Common Stock, as the case may be, issued and
outstanding by way of a reclassification, stock split (including a reverse stock
split), stock dividend or distribution, recapitalization, subdivision or other
similar transaction, the amount of Merger Consideration payable with respect to
a share of Company Common Stock shall be adjusted appropriately to provide to
holders of shares of Company Common Stock the same economic effect contemplated
by this Agreement prior to such change.

                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

    The Company represents and warrants to Sub as follows:

    SECTION 3.01. Organization, Standing and Power. Each of the Company and each
of its subsidiaries (the 'COMPANY SUBSIDIARIES') is duly organized and validly
existing under the laws of the jurisdiction in which it is organized and has
full corporate power and authority and possesses all governmental franchises,
licenses, permits, authorizations and approvals necessary to enable it to own,
lease or otherwise hold its properties and assets and to conduct its businesses
as presently conducted, other than such franchises, licenses, permits,
authorizations and approvals the lack of which, individually or in the
aggregate, has not had and could not reasonably be expected to have (i) a
material adverse effect on the business, assets, financial condition or results
of operations of the Company and the Company Subsidiaries, taken as a whole;
provided, however, that any such effect resulting from (x) changes in United
States or global economic or financial market conditions or (y) changes in
United States generally accepted accounting principles, shall not be considered
a Company Material Adverse Effect or (ii) a material adverse effect on the
ability of the Company to perform its obligations under this Agreement,
including the consummation of Merger and the other Transactions (a 'COMPANY
MATERIAL ADVERSE EFFECT'). The Company and each Company Subsidiary is duly
qualified to do business in each jurisdiction where the nature of its business
or their ownership or leasing of its properties make such qualification
necessary or the failure so to qualify has had or could reasonably be expected
to have a Company Material Adverse Effect.

    SECTION 3.02. Capital Structure. The authorized capital stock of the Company
consists of 30,000,000 shares of Company Common Stock, 10,000,000 shares of
preferred stock, without par value, of which 500 shares have been designated as
Series A1 Preferred Stock and 300 shares have been designated as Series B
Preferred Stock. At the close of business on June 14, 2001, (i) 11,438,059
shares of Company Common Stock (including 2,500 shares of Company Common Stock
issued as shares of restricted stock under the Company Stock Plans (as defined
in Section 6.04)), 500 shares of Series A1 Preferred Stock and 300 shares of
Series B Preferred Stock were issued and outstanding, (ii) 1,710,658 shares of
Company Common Stock were held by the Company in its treasury and
(iii) 2,880,251 shares of Company Common Stock were subject to outstanding
Company Employee Stock Options (as defined in Section 6.04) and 6,950,000 shares
of Company Common Stock were originally reserved for issuance pursuant to the
Company Stock Plans. Except as set forth above and except for 1,914,486 shares
of Company Common Stock reserved for issuance upon conversion of the outstanding
shares of Series B Preferred Stock, at the close of business on June 14, 2001,
no shares of capital stock or other voting securities of the Company were
issued, reserved for issuance or outstanding. All outstanding shares of Company
Capital Stock are, and all such shares that may be issued prior to the Effective
Time will be when issued, duly authorized, validly issued, fully paid and
nonassessable and not subject to or issued in violation of any purchase option,
call option, right of first refusal, preemptive right, subscription right or any
similar right under any provision of the IBCL, the Articles of Incorporation of
the Company, as amended to the date of this Agreement (the 'COMPANY CHARTER'),
the bylaws of the Company, as

                                      A-4

<Page>
amended to the date of this Agreement (the 'COMPANY BYLAWS'), or any Contract
(as defined in Section 3.04) to which the Company is a party or otherwise bound.
There are not any bonds, debentures, notes or other indebtedness of the Company
having the right to vote (or convertible into, or exchangeable for, securities
having the right to vote) on any matters on which holders of Company Capital
Stock may vote ('VOTING COMPANY DEBT'). Except as set forth above and as
provided in this Agreement, as of the date of this Agreement, there are not any
options, warrants, rights, convertible or exchangeable securities, 'phantom'
stock rights, stock appreciation rights, stock-based performance units,
commitments, Contracts, arrangements or undertakings of any kind to which the
Company or any Company Subsidiary is a party or by which any of them is bound
(i) obligating the Company or any Company Subsidiary to issue, deliver or sell,
or cause to be issued, delivered or sold, additional shares of capital stock or
other equity interests in, or any security convertible or exercisable for or
exchangeable into any capital stock of or other equity interest in, the Company
or of any Company Subsidiary or any Voting Company Debt, (ii) obligating the
Company or any Company Subsidiary to issue, grant, extend or enter into any such
option, warrant, call, right, security, commitment, Contract, arrangement or
undertaking or (iii) that give any person the right to receive any economic
benefit or right similar to or derived from the economic benefits and rights
accruing to holders of Company Capital Stock. As of the date of this Agreement,
there are not any outstanding contractual obligations of the Company or any
Company Subsidiary to repurchase, redeem or otherwise acquire any shares of
capital stock of the Company or any Company Subsidiary (other than the ILFC
Agreement and this Agreement).

    SECTION 3.03. Authority; Execution and Delivery; Enforceability. (a) The
Company has all requisite corporate power and authority to execute and deliver
this Agreement and to consummate the Merger and the other transactions
contemplated by the Transaction Agreements (the 'TRANSACTIONS'). The execution
and delivery by the Company of the Transaction Agreements and the consummation
by the Company of the Transactions have been duly authorized by all necessary
corporate action on the part of the Company, subject to the approval of the Plan
of Merger, this Agreement, the Merger and the ILFC Amendment by the holders of
the requisite number of outstanding shares of Company Common Stock and the
approval of the ILFC Amendment by the holders of a majority of the outstanding
shares of Series B Preferred Stock. The Company has duly executed and delivered
each Transaction Agreement, and each Transaction Agreement constitutes its
legal, valid and binding obligation, enforceable against it in accordance with
its terms.

    (b) The Company Board, at a meeting duly called and held, acting on the
recommendation of a special committee of the Company Board (the 'SPECIAL
COMMITTEE'), duly and unanimously adopted resolutions (i) approving this
Agreement, the Merger, the ILFC Agreement, the ILFC Amendment and the other
Transactions, (ii) determining that the terms of the Merger and the other
Transactions are fair to and in the best interests of the Company and the
holders of shares of the Company Common Stock (other than Sub and JGM), (iii)
recommending that the Company's shareholders approve the Plan of Merger, this
Agreement, the Merger and the ILFC Amendment and (iv) adopting the Plan of
Merger. On June 15, 2001, the Company Board unanimously adopted a resolution
approving the acquisition by Sub of beneficial ownership of 8,271,200 shares of
Company Common Stock. Such resolutions are sufficient to render inapplicable to
JGM, Sub, this Agreement, the Merger and the other Transactions the restrictions
on business combinations contained in Section 43-18 of the IBCL. To the
Company's knowledge, no other state takeover statute or similar statute or
regulation applies or purports to apply to the Company with respect to this
Agreement, the Merger or any other Transaction.

    (c) The only class or series of Company Capital Stock that is entitled to
vote to approve the Plan of Merger, this Agreement and the Merger is the Company
Common Stock. The affirmative vote of a majority of the outstanding shares of
the Company Common Stock and a majority of the outstanding shares of Series B
Preferred Stock, voting as separate classes, is necessary to approve the ILFC
Amendment.

    SECTION 3.04. No Conflicts; Consents. (a) Except as set forth in the letter,
dated as of the date of this Agreement, from the Company to Sub (the 'COMPANY
DISCLOSURE LETTER'), the execution and delivery by the Company of each
Transaction Agreement do not, and the consummation of the Merger and the other
Transactions and compliance with the terms hereof and thereof will not, conflict
with, or

                                      A-5

<Page>
result in any violation of or default (with or without notice or lapse of time,
or both) under, or give rise to a right of termination, cancelation or
acceleration of any obligation or to loss of a material benefit under, or result
in the creation of any pledges, liens, charges, mortgages, encumbrances and
security interests of any kind or nature whatsoever (collectively, 'LIENS') upon
any of the properties or assets of the Company or any Company Subsidiary under,
any provision of (i) the Company Charter, the Company Bylaws or the comparable
charter or organizational documents of any Company Subsidiary, (ii) any
contract, lease, license, indenture, note, bond, agreement, permit, concession,
franchise or other instrument (a 'CONTRACT') to which the Company or any Company
Subsidiary is a party or by which any of their respective properties or assets
is bound or (iii) subject to the filings and other matters referred to in
Section 3.04(b), any judgment, order or decree ('JUDGMENT') or statute, law
(including common law), ordinance, rule or regulation ('LAW') applicable to the
Company or any Company Subsidiary or their respective properties or assets,
other than, in the case of clauses (ii) and (iii) above, any such items that,
individually or in the aggregate, have not had and could not reasonably be
expected to have a Company Material Adverse Effect.

    (b) No consent, approval, license, permit, order, authorization or waiver
('CONSENT') of, or registration, declaration or filing with, or permit from, any
Federal, state, local or foreign government or any court of competent
jurisdiction, administrative agency or commission or other governmental
authority or instrumentality, domestic or foreign (a 'GOVERNMENTAL ENTITY') is
required to be obtained or made by or with respect to the Company or any Company
Subsidiary in connection with the execution, delivery and performance of any
Transaction Agreement or the consummation of the Merger and the other
Transactions, other than (i) the filing with the Securities and Exchange
Commission (the 'SEC') of a Transaction Statement on Schedule 13E-3 (as amended
from time to time, the 'SCHEDULE 13E-3'), (B) a proxy statement relating to the
approval of the Plan of Merger, this Agreement, the Merger and the ILFC
Amendment by the holders of shares of Company Common Stock (as amended from time
to time, the 'PROXY STATEMENT') and (C) such reports under Sections 13 and 16 of
the Securities Exchange Act of 1934, as amended (the 'EXCHANGE ACT'), as may be
required in connection with any Transaction Agreement, the Merger and the other
Transactions, (ii) the filing of the Articles of Merger and the ILFC Amendment
with the office of the Secretary of State of the State of Indiana and
appropriate documents with the relevant authorities of the other jurisdictions
in which the Company is qualified to do business, (iii) any filings required
under the rules and regulations of the Department of Transportation (the 'DOT'),
(iv) compliance with and such filings as may be required under applicable
environmental Laws, (v) such filings as may be required in connection with the
taxes described in Section 6.08, (vi) filings under any applicable state
takeover Law and (vii) such other items that, individually or in the aggregate,
have not had and could not reasonably be expected to have a Company Material
Adverse Effect.

    SECTION 3.05. SEC Documents; Undisclosed Liabilities. The Company has filed
all reports, schedules, forms, statements and other documents required to be
filed by the Company with the SEC since January 1, 1999 (the 'COMPANY SEC
DOCUMENTS'). As of its respective date, each Company SEC Document complied as to
form in all material respects with the requirements of the Exchange Act or the
Securities Act of 1933, as amended (the 'SECURITIES ACT'), as the case may be,
and the rules and regulations of the SEC promulgated thereunder applicable to
such Company SEC Document, and did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The consolidated
financial statements of the Company included in the Company SEC Documents comply
as to form in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with generally accepted accounting principles ('GAAP')
(except, in the case of unaudited statements, as permitted by Form 10-Q of the
SEC) applied on a consistent basis during the periods involved (except as may be
indicated in the notes thereto) and fairly present the consolidated financial
position of the Company and its consolidated subsidiaries as of the dates
thereof and the consolidated results of their operations and cash flows for the

of the Company, Sub and JGM shall as soon as practicable following the date
hereof prepare and file with the SEC the Schedule 13E-3 and the Company shall as
soon as practicable following the date hereof prepare and file with the SEC the
Proxy Statement in preliminary form, and each of the Company and Sub shall use
its reasonable efforts to respond as promptly as practicable to any comments of
the SEC with respect thereto. Each of the Company, Sub and JGM shall notify the
others promptly of the receipt of any comments from the SEC or its staff and of
any request by the SEC or its staff for amendments or supplements to the
Schedule 13E-3 and the Proxy Statement or for additional information and shall
supply the others with copies of all correspondence between it or him, as the
case may be, or any of its or his, as the case may be, representatives, on the
one hand, and the SEC or its staff, on the other hand, with respect to the
Schedule 13E-3 and the Proxy Statement, as applicable. If at any time prior to
receipt of the Company Shareholder Approval there shall occur any event that
should be set forth in an amendment or supplement to the Proxy Statement, the
Company shall promptly prepare and mail to its shareholders such an amendment or
supplement. The Company shall not mail any Proxy Statement, or any amendment or
supplement thereto, to which Sub reasonably objects. The Company shall use its
reasonable best efforts to cause the Proxy Statement to be mailed to the
Company's shareholders as promptly as practicable after filing with the SEC.

    (b) The Company shall as soon as practicable following the date hereof, duly
call, give notice of, convene and hold a meeting of its shareholders (the

holders of Company Common Stock of the Plan of Merger, this Agreement, the
Merger and the ILFC Amendment. For the avoidance of doubt, (i) the Company may

Merger, this Agreement, the Merger and the ILFC Amendment to the requisite
holders of shares of Company Capital Stock at an annual meeting which was
previously adjourned and (ii) the Company may present such matters as a

                                      A-9

Statement shall include a description of the recommendations referred to in
Section 3.03(b), and neither the Company Board nor any committee thereof shall
withdraw or modify, or propose to withdraw or modify such recommendations or
related approval; provided, however, that the Company Board or the Special
Committee may determine not to make such recommendations or to withdraw or
modify such recommendations if the Special Committee determines in good faith,
after consulting with and based on the advice of outside legal counsel, that
such recommendations would be inconsistent with its fiduciary duties to the
holders of shares of Company Common Stock (other than Sub and JGM) under
applicable law. Without limiting the generality of the foregoing, the Company
agrees that its obligations pursuant to the first sentence of this Section
6.01(b) shall not be affected by the withdrawal or modification by either the
Company Board or the Special Committee of its approval or recommendation of the
Plan of Merger, this Agreement, the Merger or the ILFC Amendment.

    (c) Sub shall cause all shares of Company Common Stock owned by it and all
of its affiliates (other than the Company, the Company Subsidiaries and the

commitments, personnel and records and, during such period, the Company shall,
and shall cause each of its subsidiaries to, furnish promptly to Sub (a) a copy
of each report, schedule, registration statement and other document filed by it
during such period pursuant to the requirements of Federal or state securities
laws and (b) all other information concerning its business, properties and
personnel as Sub may reasonably request.

subject to the conditions set forth in this Agreement, each of the parties shall
use its reasonable best efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, and to assist and cooperate with the other parties
in doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the other
Transactions, including (i) the obtaining of all necessary actions or
nonactions, waivers, consents and approvals from Governmental Entities and the
making of all necessary registrations and filings (including filings with
Governmental Entities, if any) and the taking of all reasonable steps as may be
necessary to obtain an approval or waiver from, or to avoid an action or
proceeding by, any Governmental Entity, (ii) the obtaining of all necessary
consents, approvals or waivers from third parties, (iii) the defending of any
lawsuits or other legal proceedings, whether judicial or administrative,
challenging this Agreement, the Merger or the consummation of the Transactions,

court or other Governmental Entity vacated or reversed, (iv) the execution and
delivery of any additional instruments necessary to consummate the Transactions
and to fully carry out the purposes of each Transaction Agreement and (v) to
arrange for the financing contemplated by the Commitment Letter to be provided
on substantially the terms and conditions specified in the Commitment Letter. In
connection with and without limiting the foregoing, the Company and the Company
Board shall (i) take all action necessary to ensure that no state takeover
statute or similar statute or regulation is or becomes applicable to the Merger
or any other Transaction or any Transaction Agreement, (ii) if any state
takeover statute or similar statute or regulation becomes applicable to any
Transaction Agreement, take all action necessary to ensure that the Merger and
the other Transactions may be consummated as promptly as practicable on the
terms contemplated by each Transaction Agreement and otherwise to minimize the
effect of such statute or regulation on the Merger and the other Transactions
and (iii) cooperate with the arrangements for obtaining the Financing. Nothing
in this Agreement shall be deemed to require any party to waive any substantial
rights or agree to any substantial limitation on its operations or to dispose of
any significant asset or collection of assets.

    (b) The Company shall give prompt notice to Sub, and Sub shall give prompt
notice to the Company, of (i) any representation or warranty made by it
contained in any Transaction Agreement to which it is a party that is qualified
as to materiality becoming untrue or inaccurate in any respect or any such
representation or warranty that is not so qualified becoming untrue or
inaccurate in any material

                                      A-10

<Page>
respect or (ii) the failure by it to comply with or satisfy in any material
respect any covenant, condition or agreement to be complied with or satisfied by

Transaction Agreement.

of this Agreement, the Company Board (or, if appropriate, any committee thereof
with responsibility for the administration of the Company Stock Plans) shall

to the adjustment of the terms of all outstanding Company Employee Stock Options
heretofore granted under any Company Stock Plan) to provide that each Company
Employee Stock Option, other than Company Employee Stock options held by the
persons listed on Schedule 6.04(a) of the Company Disclosure Letter (the
'ROLLOVER INDIVIDUALS'), whether vested or unvested, outstanding at the
Effective Time shall be converted into the right to receive from the Surviving
Corporation an amount equal to (i) the excess, if any, of (x) the Merger
Consideration over (y) the exercise price per share of Company Common Stock
subject to such Company Employee Stock Option, multiplied by (ii) the number of
shares of Company Common Stock for which such Company Employee Stock Option
shall not theretofore have been exercised.

    (b) As soon as practicable following the date of this Agreement, the Company
Board (or, if appropriate, any committee thereof with responsibility for the
administration of the Company Stock Plans) shall adopt such resolutions or take
such other actions as are required (with respect to the adjustment of the terms
of all outstanding Company Restricted Shares heretofore granted under any
Company Stock Plan) to provide that the Restriction Period with respect to each
Company Restricted Share, whether vested or unvested, shall be deemed to expire
immediately prior to the Effective Time, unless any such Restriction Period
would otherwise expire sooner in accordance with the terms of the applicable
Company Stock Plan, in which case, such Restriction Period shall expire in
accordance with the terms of the applicable Company Stock Plan.

    (c) All amounts payable pursuant to this Section 6.04 shall be subject to
any required withholding of taxes required by applicable Law and shall be paid
without interest. The Company shall use its reasonable best efforts to obtain
the consent of all holders of Company Employee Stock Options as shall be
necessary to effectuate the foregoing. Notwithstanding anything to the contrary
contained in this Agreement, payment as to a particular holder shall, at Sub's
request, be withheld in respect of any Company Employee Stock Option until all
necessary consents are obtained from such holder.

    (d) The Company Stock Plans shall terminate as of the Effective Time, and
the provisions in any other benefit plan providing for the issuance, transfer or
grant of any capital stock of the Company or any interest in respect of any
capital stock of the Company shall be deleted as of the Effective Time, and the
Company shall ensure that following the Effective Time, except for the Rollover
Individuals, no holder of a Company Employee Stock Option or any participant in
any Company Stock Plan shall have any right thereunder to acquire any capital
stock of the Company or the Surviving Corporation.

    (e) The Company shall enter into option modification agreements as of the
Effective Time with each of the Rollover Individuals in the form attached hereto

such other actions as are necessary in connection with such option modification
agreements.

    (f) The Company shall ensure that (i) as of the date of this Agreement, all

indemnify (including any obligations to advance funds for expenses) the current
or former directors or officers of the Company for acts or omissions by such
directors and officers occurring prior to the Effective Time to the extent that
such obligations of the Company exist on the date of this Agreement, whether

agreements or otherwise, and such obligations shall survive the Merger and shall
continue in full force and effect in accordance with the terms of the Company
Charter, the Company Bylaws and such individual indemnity agreements from the
Effective Time until the expiration of the applicable statute of limitations
with respect to any claims against such directors or officers arising out of
such acts or omissions.

    (b) For a period of six years after the Effective Time, the Surviving
Corporation shall maintain in effect the current policies of directors' and
officers' liability insurance maintained by the Company (provided that the
Surviving Corporation may substitute therefor policies with reputable and
financially sound carriers of at least the same coverage and amounts containing
terms and conditions which are no less advantageous) with respect to claims
arising from or related to facts or events which occurred at or before the

returns with respect to such Transfer Taxes.

Proxy Statement or any amendment or supplement thereto or in the Schedule 13E-3

first mailed to Company's shareholders and at the time of the Company
Shareholders Meeting, contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements made therein,

respective officers or directors is discovered by the Company, the Special
Committee or Sub which should be set forth in an amendment or supplement to the
Proxy Statement or the Schedule 13E-3, as the case may be, so that such document
would not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading, the party
discovering such information shall promptly notify each other party and, to the
extent required by applicable Law, an appropriate amendment or supplement
describing such information shall be filed promptly with the SEC and, to the
extent required by applicable Law, disseminated to the Company's shareholders.

    matters properly presented to the shareholders of the Company or
    (iv) seeking to prohibit JGM from effectively controlling in any material
    respect the business or operations of the Company and the Company
    Subsidiaries.

    Closing Date as though made on the Closing Date, except to the extent such
    representations and warranties expressly relate to an earlier date (in which
    case such representations and warranties qualified as to materiality shall
    be true and correct, and those not so qualified shall be true and correct in
    all material respects, on and as of such earlier date). Sub shall have
    received a certificate signed on behalf of the Company by a duly authorized

    excluding, however, any such event which is the direct result of (i) any
    action or negligent or willful failure to take an action on the part of Sub,
    (ii) any action or negligent or willful failure to take an action on the
    part of the Company which is contrary to, or materially inconsistent with,
    the recommendation or direction, as case may be, of the Special Committee,
    (iii) any action with respect to which the recommendation or direction, as
    the case may be, of the Special Committee is required hereunder which is
    taken by the Company without such recommendation or direction, as the case

    have been provided on substantially the terms and conditions specified in

    such other financing sources, as are acceptable to ATA and are not
    materially more onerous in the aggregate to ATA than those specified in the
    Commitment Letter; provided, however, that this condition shall be deemed
    satisfied if the failure of this condition is due to any action or failure
    to take an action on the part of the Company or ATA taken at the direction
    of JGM or any of his affiliates (other than the Company Subsidiaries (other
    than ATA) and the Excluded Affiliates).

    case such representations and warranties qualified as to materiality shall
    be true and correct, and those not so qualified shall be true and correct in
    all material respects, on and as of such earlier date). The Company shall
    have received a certificate signed on behalf of Sub by the President of Sub
    to such effect.

        (b) Performance of Obligations of Sub. Sub shall have performed in all
    material respects all obligations required to be performed by it under this

                                  ARTICLE VIII
                       TERMINATION, AMENDMENT AND WAIVER

    SECTION 8.01. Termination. This Agreement may be terminated at any time
prior to the Effective Time, whether before or after satisfaction of the
condition set forth in Section 7.01(a):

        (a) by mutual written consent of Sub and the Company Board on behalf of
    the Company (as agreed to by the Special Committee);

        (b) by either Sub or the Company (acting at the direction of the Special
    Committee):

           (i) if the Merger is not consummated on or before October 31, 2001
       (the 'OUTSIDE DATE'), unless the failure to consummate the Merger is the
       result of a breach of this Agreement by the party seeking to terminate
       this Agreement (it being understood that any breach of this Agreement by
       the Company without the consent of the Special Committee shall not
       constitute a breach for purposes of this Section 8.01(b)(i)); provided,
       however, that the passage of such period shall be tolled for any part
       thereof during which any party shall be subject to a nonfinal order,
       decree, ruling or action restraining, enjoining or otherwise prohibiting
       the consummation of the Merger; or

           (ii) if any Governmental Entity issues an order, decree or ruling or
       takes any other action permanently enjoining, restraining or otherwise
       prohibiting the Merger and such order, decree, ruling or other action
       shall have become final and nonappealable.

        (c) by Sub, if the Company breaches or fails to perform in any material
    respect any of its representations, warranties or covenants contained in
    this Agreement, which breach or failure to perform (i) would give rise to
    the failure of a condition set forth in Section 7.02(a) or 7.02(b), and
    (ii) cannot be or has not been cured within 30 days after the giving of
    written notice to the Company of such breach (provided that Sub is not then
    in material breach of any representation, warranty or covenant contained in
    this Agreement); excluding, however, any such breach or failure to perform
    by the Company that involves a matter for which the consent or
    recommendation, as the case may be, of the Special Committee is required
    hereunder for which (i) such breach or failure to perform by the Company is
    contrary to, or materially inconsistent with, the recommendation or
    direction, as the case may be, of the Special Committee or (ii) such
    recommendation or direction, as the case may be, has not been obtained.

        (d) by the Company (acting at the direction of the Special Committee),
    if Sub breaches or fails to perform in any material respect any of its
    representations, warranties or covenants contained in this Agreement, which
    breach or failure to perform (i) would give rise to the failure of a
    condition set forth in Section 7.03(a) or 7.03(b), and (ii) cannot be or has
    not been cured within 30 days after the giving of written notice to Sub of
    such breach (provided that the Company is not then in material breach of any
    representation, warranty or covenant contained in this Agreement).

        (e) by Sub, if the Company Board or the Special Committee withdraws or
    modifies, or publicly proposes to withdraw or modify, in a manner adverse to
    Sub its approval or recommendation of the Plan of Merger, this Agreement,
    the Merger or the ILFC Amendment or fails to recommend to the Company's
    shareholders that they vote to approve the Plan of Merger, this Agreement,
    the Merger and the ILFC Amendment.

        (f) by either Sub or the Company (acting at the direction of the Special
    Committee), if at the Company Shareholders Meeting a majority of the
    outstanding shares of Company Common Stock shall not have voted in favor of
    the Plan of Merger, this Agreement, the Merger and the ILFC Amendment and a
    majority of the shares of Company Common Stock voted at the Company
    Shareholder Meeting (other than shares owned by JGM, Sub or any other
    affiliate of JGM (other than the Excluded Affiliates)) shall not have voted
    in favor of approval of the Plan of Merger, this Agreement and the Merger.

    SECTION 8.02. Effect of Termination. In the event of termination of this
Agreement by either the Company or Sub as provided in Section 8.01, this
Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Sub or the Company, other than Section 3.06,
Section 4.05, Section 6.07, this Section 8.02 and Article IX, which provisions
shall survive such

                                      A-15

<Page>
termination, and except to the extent that such termination results from the
material breach by a party of any representation, warranty or covenant set forth
in this Agreement.

    SECTION 8.03. Amendment. This Agreement may be amended by the parties at any
time before or after receipt of the approval of the Company's shareholders at
the Company Shareholder Meeting; provided, however, that any amendment pursuant
to this Section 8.03 shall require the approval of the Special Committee;
provided further, however, that after receipt of such approval, there shall be
made no amendment that by Law requires further approval by the shareholders of
the Company without the further approval of such shareholders. This Agreement
may not be amended except by an instrument in writing signed on behalf of each
of the parties.

    SECTION 8.04. Extension; Waiver. At any time prior to the Effective Time,
the parties may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties contained in this Agreement or in any
document delivered pursuant to this Agreement or (c) subject to the proviso of
Section 8.03, waive compliance with any of the agreements or conditions
contained in this Agreement; provided, however, that any extension or waiver by
the Company pursuant to this Section 8.04 shall require the approval of the
Special Committee. Any agreement on the part of a party to any such extension or
waiver shall be valid only if set forth in an instrument in writing signed on
behalf of such party. The failure of any party to this Agreement to assert any
of its rights under this Agreement or otherwise shall not constitute a waiver of
such rights.

    SECTION 8.05. Procedure for Termination, Amendment, Extension or Waiver. A
termination of this Agreement pursuant to Section 8.01, an amendment of this
Agreement pursuant to Section 8.03 or an extension or waiver pursuant to
Section 8.04 shall, in order to be effective, require (i) in the case of Sub,
action by its Board of Directors, and (ii) in the case of the Company, the
direction or approval of the Special Committee, as applicable, or, in either
case, to the extent permitted by law, its duly authorized designee.

                                   ARTICLE IX

                                 PLAN OF MERGER

    Amtran, Inc., an Indiana corporation (the 'COMPANY') or, as of the Effective
Time (as defined in Section 1 below), the 'SURVIVING CORPORATION'), and INDUS
Acquisition Company, an Indiana corporation ('SUB'), hereby adopt the following
Plan of Merger for purposes of Section 40-1 of the Indiana Business Corporation
Law (the 'IBCL'):

    1. Articles of Merger. In accordance with the requirements of the IBCL,
Articles of Merger shall be prepared, executed and submitted for filing with the
office of the Secretary of State of the State of Indiana as soon as practicable
following the closing of the Merger (as defined in Section 2 below). The date of
such filing is referred to as the 'EFFECTIVE TIME'.

    2. Merger; Articles; Bylaws. At the Effective Time, (i) Sub shall merge with
and into the Company (the 'MERGER') and as a result thereof, the separate
existence of Sub shall cease, (ii) the Articles of Incorporation of the Company,
as in effect immediately prior to the Effective Time, shall constitute the
Articles of Incorporation of the Surviving Corporation (the 'ARTICLES') and
(iii) the Bylaws of the Company, as in effect immediately prior to the Effective
Time, shall be the Bylaws of the Surviving Corporation (the 'BYLAWS').

    3. Effects of the Merger. At the Effective Time: (a) title to all real
estate and other property owned by Sub and the Company shall be vested in the
Surviving Corporation without reversion or impairment; (b) the Surviving
Corporation shall have all liabilities of Sub and the Company; (c) a proceeding
pending against Sub or the Company may be continued as if the Merger did not
occur or the Surviving Corporation may be substituted in the proceeding for Sub;
and (d) the shares of capital stock of Sub and shares of common stock, without
par value, of the Company ('COMPANY COMMON STOCK') shall be converted as
provided in Section 6 hereof.

    4. Directors. The directors of the Company immediately prior to the
Effective Time shall be the directors of the Surviving Corporation, until the
earlier of their resignation or removal or until their respective successors are
duly elected and qualified, as the case may be.

    5. Officers. The officers of the Company immediately prior to the Effective
Time shall be the officers of the Surviving Corporation, until the earlier of
their resignation or removal or until their respective successors are duly
elected or appointed and qualified, as the case may be.

    6. Effect on the Capital Stock of the Constituent Corporations; Exchange of
Certificates. The following provisions of this Plan of Merger shall govern the
manner and basis of converting the shares of Company Common Stock and shares of
capital stock of Sub into shares, obligations, or other securities of the
Surviving Corporation.

    6.1. Effect on Capital Stock. At the Effective Time, by virtue of the Merger
and without any action on the part of the holder of any shares of capital stock
of the Company or any shares of capital stock of Sub:

        (a) Capital Stock of Sub. Each issued and outstanding share of capital
    stock of Sub shall be converted into and become one fully paid and
    nonassessable share of common stock, without par value, of the Surviving
    Corporation.

        (b) Cancelation of Treasury, JGM-Owned and Sub-Owned Stock. Each share
    of Company Common Stock that is owned by the Company, J. George Mikelsons
    ('JGM'), Sub or any other affiliate of JGM (other than any person who is
    deemed to be an affiliate of JGM by reason of such person's position as an
    officer or director of the Company) shall no longer be outstanding and shall
    automatically be canceled and retired and shall cease to exist, and no
    consideration shall be delivered or deliverable in exchange therefor. Each
    share of Company Common Stock that is owned by any subsidiary of the Company
    shall automatically be converted into one fully paid and nonassessable share
    of common stock, without par value, of the Surviving Corporation.

        (c) Conversion of Company Capital Stock. (1) Subject to Section 6.1(b),
    each issued share of Company Common Stock shall be converted into the right
    to receive from the Surviving Corporation $23.00 in cash, without interest.

                                      A-19

<Page>
        (2) Each issued share of Preferred Stock of the Company shall remain
    outstanding.

        (3) The cash payable upon the conversion of shares of Company Common
    Stock pursuant to this Section 6.1(c) is referred to collectively as the
    'MERGER CONSIDERATION'. At the Effective Time, all such shares of Company
    Common Stock shall no longer be outstanding and shall automatically be
    canceled and retired and shall cease to exist, and each holder of a
    certificate that immediately prior to the Effective Time represented any
    such shares of Company Common Stock (each, a 'CERTIFICATE') shall cease to
    have any rights with respect thereto, except the right to receive Merger
    Consideration upon surrender of a Certificate in accordance with
    Section 6.2, without interest.

        SECTION 6.2. Exchange of Certificates.

        (a) Paying Agent. Prior to the Effective Time, Sub shall designate a
    bank or trust company to act as paying agent (the 'PAYING AGENT') for the
    payment of the Merger Consideration upon surrender of Certificates. Promptly
    following the Effective Time, the Surviving Corporation shall provide to the
    Paying Agent cash in an amount sufficient to pay for the shares of Company
    Common Stock converted into the right to receive cash pursuant to
    Section 6.1(c) (such cash being hereinafter referred to as the 'EXCHANGE
    FUND'). All of the fees and expenses of the Paying Agent shall be borne by
    the Surviving Corporation.

        (b) Exchange Procedure. The Surviving Corporation shall cause the Paying
    Agent to mail promptly after the Effective Time (but, in any event, within
    five days after the Effective Time) to each holder of record of
    Certificates, (i) a form of letter of transmittal (which shall specify that
    delivery shall be effected, and risk of loss and title to Certificates shall
    pass, only upon delivery of Certificates to the Paying Agent and shall be in
    such form and have such other provisions as the Surviving Corporation may
    reasonably specify) and (ii) instructions for use in effecting the surrender
    of Certificates in exchange for Merger Consideration. Upon surrender of a
    Certificate for cancelation to the Paying Agent, together with such letter
    of transmittal, duly completed and validly executed, and such other
    documents as may reasonably be required by the Paying Agent, the holder of
    such Certificate shall be entitled to receive in exchange therefor the
    amount of cash into which the shares of Company Common Stock theretofore
    represented by such Certificate shall have been converted pursuant to
    Section 6.1(c) and the Certificate so surrendered shall forthwith be
    canceled; the Surviving Corporation shall enter into a paying agency
    agreement with the Paying Agent which provides that the Paying Agent shall
    promptly following any such surrender of Certificates (but, in any event,
    within three business days after the Paying Agent receives such
    Certificates) dispatch by mail payment of such amount to such holder. In the
    event of a transfer of ownership of Company Common Stock that is not
    registered in the transfer records of the Company, payment may be made to a
    person other than the person in whose name the Certificate so surrendered is
    registered, if such Certificate shall be properly endorsed or otherwise be
    in proper form for transfer and the person requesting such payment shall pay
    any transfer or other taxes required by reason of the payment to a person
    other than the registered holder of such Certificate or establish to the
    satisfaction of the Surviving Corporation that such tax has been paid or is
    not applicable. Until surrendered as contemplated by this Section 6.2, each
    Certificate shall be deemed at any time after the Effective Time to
    represent only the right to receive upon such surrender the amount of cash,
    without interest, into which the shares of Company Common Stock theretofore
    represented by such Certificate have been converted pursuant to
    Section 6.1(c). No interest shall be paid or shall accrue on the cash
    payable upon surrender of any Certificate.

        (c) No Further Ownership Rights in Company Common Stock. The Merger
    Consideration paid upon surrender of a Certificate in accordance with the
    terms of this Plan of Merger shall be deemed to have been paid in full
    satisfaction of all rights pertaining to the shares of Company Common Stock
    formerly represented by such Certificate, and after the Effective Time there
    shall be no further registration of transfers on the stock transfer books of
    the Surviving Corporation of shares of Company Common Stock that were
    outstanding immediately prior to the Effective Time. If, after the Effective
    Time, any Certificates are presented to the Surviving Corporation or the
    Paying Agent for any reason, they shall be canceled and exchanged for the
    amount of cash into which the shares of Company Common Stock theretofore
    represented by such Certificates shall have been converted as provided in
    this Plan of Merger.

                                      A-20

        (d) No Liability. None of Sub, the Company or the Paying Agent shall be
    liable to any person in respect of any cash from the Exchange Fund that is
    required under applicable Law to be delivered to a public official pursuant
    to any applicable abandoned property, escheat or similar law.

        (e) Investment of Exchange Fund. The Surviving Corporation shall direct
    the Paying Agent to invest any cash included in the Exchange Fund, as
    directed by the Surviving Corporation, on a daily basis. Any interest and
    other income resulting from such investments shall be paid to the Surviving
    Corporation.

        (f) Withholding Rights. The Surviving Corporation shall be entitled to
    deduct and withhold, as required by applicable Law, any applicable taxes
    from the consideration otherwise payable to any holder of Company Common
    Stock pursuant to this Agreement.

        (g) Lost, Stolen or Destroyed Certificates. In the event any Certificate
    shall have been lost, stolen or destroyed, the holder of such lost, stolen
    or destroyed Certificate shall execute an affidavit of that fact upon
    request. The holder of any such lost, stolen or destroyed Certificate shall
    also deliver a reasonable indemnity against any claim that may be made
    against the Surviving Corporation or the Paying Agent with respect to the
    Certificate alleged to have been lost, stolen or destroyed. The affidavit
    and any indemnity which may be required hereunder shall be delivered to the
    Paying Agent, who shall be responsible for making payment for such lost,
    stolen or destroyed Certificate pursuant to the terms hereof.

        (h) Adjustment to Prevent Dilution. In the event that following the date
    hereof and prior to the Effective Time the Company changes the number of
    shares of Company Common Stock or securities convertible or exchangeable
    into or exercisable for shares of Company Common Stock, as the case may be,
    issued and outstanding by way of a reclassification, stock split (including
    a reverse stock split), stock dividend or distribution, recapitalization,
    subdivision, or other similar transaction, the amount of Merger
    Consideration payable with respect to a share of Company Common Stock shall
    be adjusted appropriately to provide holders of shares of Company Common
    Stock the same economic effect contemplated by this Plan of Merger prior to
    such change.

                                                                   June   , 2001

                      Re: Amendment of Stock Option Terms

Dear [Name of Officer]:

    As you know, INDUS Acquisition Company ('SUB') and Amtran, Inc. ('AMTRAN')
have entered into an Agreement and Plan of Merger dated as of June 18, 2001 (the
'MERGER AGREEMENT'), pursuant to which Sub will be merged into Amtran (the
'MERGER'). Under the Merger Agreement, Amtran has agreed to enter into option
modification agreements by the time the Merger becomes effective with certain
officers with respect to their options to purchase shares of Amtran common stock
(the 'OFFICER OPTIONS') remaining outstanding following the consummation of the
Merger. The purpose of this letter agreement is to amend your option agreements
to set forth the terms on which your Officer Options would remain outstanding
following the consummation of the Merger. Except as provided in Section 2
hereof, this agreement will become effective only upon completion of a
transaction that is approved by the Board of Directors and the shareholders of
Amtran involving the acquisition, directly or indirectly, by Mikelsons of the
outstanding shares of Amtran common stock he does not currently own (a
'TRANSACTION').

    Amtran and you each agree as follows:

    1. The terms of each of your outstanding and unexercised Officer Options
granted pursuant to the 1993 Incentive Stock Plan for Key Employees of Amtran
and its Subsidiaries, the 1996 Incentive Stock Plan for Key Employees of Amtran
and its Subsidiaries and/or the 2000 Incentive Stock Plan for Key Employees of
Amtran and its Subsidiaries (collectively, the 'OPTION PLANS') and the stock
option agreements thereunder, which Officer Options are set forth on Schedule 1
hereto, shall be modified effective as of the consummation of a Transaction as
set forth in the 'DESCRIPTION OF OPTION ROLLOVER PROPOSAL' attached as Annex A
('ANNEX A').

    2. Effective as of the date hereof, you agree, notwithstanding the terms of
the Option Plans and the agreements thereunder, not to exercise your Officer
Options from the date hereof until the earlier to occur of: (i) the consummation
of a Transaction or (ii) the termination of the Merger Agreement in accordance
with its terms.

    3. By entering into this Agreement, you agree and acknowledge that you have
received and read the tax disclosure contained in Annex A. You acknowledge that
you have had the opportunity to consult with your own tax advisor as to the
specific tax consequences of the proposed modifications to your Officer Options.

    4. By entering into this Agreement, you acknowledge that the issuance of
shares of Amtran common stock received upon exercise of such options will be a
private placement which will not be registered under the Securities Act and that
such shares will be 'RESTRICTED SECURITIES' as defined in Rule 144 under the
Securities Act of 1933, as amended.

    5. Amtran is permitted to cause any wholly owned subsidiary to perform, in
whole or in part, any of Amtran's obligations under this Agreement, including,
without limitation, those set forth on Annex A, provided that any such action by
Amtran shall not release it from its obligations hereunder.

    6. The interpretation, performance and enforcement of this agreement shall
be governed by the laws of the state of Indiana without regard to principles of
conflicts of law.

    7. This agreement may be signed in counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.

    Except as specifically provided herein, the terms and conditions of your
Officer Options as set forth in the Option Plans and stock option agreements
thereunder will continue to apply and remain in full

                                      A-22

force and effect. You acknowledge that your agreement to the terms and
conditions of this letter agreement is an inducement to Mikelsons' willingness
to consummate a Transaction.

                                          Very truly yours,

                                          AMTRAN, INC.,

                                          By:  .................................

                                  AMTRAN, INC.
                         DESCRIPTION OF OPTION ROLLOVER

BACKGROUND

     As the Company announced on May 16, 2001, J. George Mikelsons has proposed
     taking the Company private in a transaction in which all the outstanding
     shares would be exchanged for a cash payment. On June 18, 2001, the Company
     entered into a merger agreement with respect to that proposal.

     Approval of the proposed transaction by the Board of Directors resulted in
     the acceleration of vesting of all outstanding stock options held by
     officers (i.e., all options held by officers have become immediately
     exercisable).

     Under the proposal, all in-the-money options held by non-officers would be
     cashed out at the closing of the proposed transaction. All out-of-the-money
     options held by non-officers would be canceled without payment, in exchange
     for the acceleration of vesting of options that would not otherwise vest.

OVERVIEW OF THE PROPOSAL TO OFFICERS

     The merger agreement for the proposed transaction provides that the Company
     will enter into option modification agreements with the members of the
     officer group under which they would agree to continue to hold their
     options with certain modifications as described below.

     Officers would agree to defer exercise of their options. In 2002 and
     thereafter, options would be exercisable not less frequently than annually
     until the expiration of options in accordance with their terms (i.e.,
     maturity dates would not be extended).

     In order to provide liquidity so long as the Company is private, officers
     would have the right to put shares acquired upon exercise of their options
     annually for three put periods following exercise. These put rights would
     expire if the Company's common stock ever becomes publicly traded again.

     Except for the modifications described in this summary, the terms of the
     existing option agreements with respect to the officer group would not be
     modified.

     Exhibit A to this summary contains certain timetables illustrating the
     exercise and put mechanics.

EXERCISE MECHANICS

     The terms of the options held by officers would be modified to provide that
     options are only exercisable during a 60-day period each year beginning on
     June 1. The first regularly scheduled exercise period would start on
     June 1, 2002. In no event would an option be permitted to be exercised
     beyond its existing expiration date.

     Exercises of options during an exercise period would be subject to two
     conditions on the date of exercise:

           -- the Company must have the ability under the terms of its
          outstanding debt (including the Company's existing indentures, the
          secured credit facility to be entered into in connection with the
          proposed transaction and future indentures and credit facilities) to
          make the corresponding put payment (discussed below) on the exercise
          date; and

           -- after making the corresponding put payments, the Company must be
          able to satisfy a minimum cash test of either (x) $125 million in cash
          and cash equivalents or (y) $200 million in cash, cash equivalents and
          availability under the new secured credit facility.

                                      A-25

<Page>
     If on any day during an exercise period some but not all option exercises
     would be permitted under these two conditions, then officers exercising on
     that day would be permitted to exercise only in part (allocated among those
     exercising pro rata (based on the number of options requested to be
     exercised)).

     The Company would loan on a full-recourse basis at a market rate of
     interest to current officers the exercise price of their options (other
     than incentive stock options, or 'ISOS') and withholding taxes resulting
     from option exercises. These loans would be required to be repaid at the
     time the shares received upon exercise are put or, if earlier, at the end
     of the third put period following the exercise date. Interest would be
     payable annually on these loans either in the form of cash or in the form
     of an additional note.

     Holders of ISOs would not automatically be entitled to receive such a loan
     but could apply for a loan from the Company to the extent that such a loan
     would not disqualify the ISOs. The terms of this loan would differ from the
     terms of the loans made available to holders of nonqualified stock options
     to the extent necessary to comply with the IRS rules relating to ISOs.

PUT RIGHT

     In order to provide liquidity to optionholders once the Company is private
     (since there would be no public market for the Company's shares), officers
     would have the right to put their shares to the Company during a 60-day
     period beginning on December 15 of each year; provided, that no officer
     will be permitted to put his or her shares to the Company prior to the
     expiration of 6 months following the date on which such shares were
     acquired pursuant to the exercise of an option. The first put period would
     start on December 15, 2002.

     In order for the Company to obtain favorable accounting treatment with
     respect to the put right, officers would be required to hold their shares
     for a minimum of 6 months following the date of option exercise. For this
     reason, put notices would become effective no earlier than 6 months after
     the end of the immediately preceding exercise period. An exception is made
     to this requirement in the case of the death of an officer.

     Officers would have the right to put shares at a price per share to be
     determined by an independent third-party appraiser shortly prior to each
     year's exercise period. The valuation methodology for the put right would
     be the same method used for valuations under the preferred stock held by
     ILFC. Until the first valuation is completed (presently anticipated to be
     in the first quarter of 2002), the put price would be the price per share
     paid in the proposed transaction.

     If a holder exercises his or her options but decides not to put his or her
     shares until a put period that occurs after a new valuation, the put price
     would be the new valuation price, which could be higher or lower than the
     price per share paid in the proposed transaction.

     A put would become effective 30 days after the officer delivers a put
     notice.

     Except as described below, the put right with respect to particular shares
     would expire at the end of the fifth put period after the date of option
     exercise with respect to such shares.

TREATMENT OF OPTIONS AND SHARES UPON RETIREMENT OR DISABILITY

     The options held by an officer who retires at or after age 60 or leaves
     employment because of a Disability (as defined in the existing option plans
     and agreements) would be exercisable through the end of the first exercise
     period ending after the date of retirement or Disability, unless the option
     would otherwise expire sooner under its existing terms. For example, an
     officer who retires in January of a year with unexercised options would be
     required to exercise his or her options on or before July 30 of that year.

     To the extent that a regularly scheduled exercise period would not occur
     prior to expiration of an option, the retired or Disabled officer would be
     permitted to deliver an exercise notice during a special individual
     exercise period beginning 5 days prior to the date on which that option
     would expire and ending on the date the option would expire (i.e., the
     former officer would be permitted to exercise during the last five days the
     option is outstanding). An exercise notice

                                      A-26

<Page>
     would become effective immediately unless the conditions to exercise set
     forth under 'EXERCISE MECHANICS' would not be satisfied on the date of
     delivery, in which case the exercise notice would become effective on the
     first date on which those conditions would be satisfied. The exercise price
     would be paid on the date an exercise notice becomes effective.

     A former officer would have the put rights described above, except that the
     former officer's put rights would expire at the end of the first put period
     after the date of exercise during which the former officer is permitted to
     put his or her shares.

     The Company would have a call (which would become exercisable upon the
     expiration of the former officer's put rights) over the officer's shares at
     the then-current valuation price.

     The Company would make a loan available to former officers after retirement
     or termination of employment for Disability to the extent set forth above
     under the heading 'EXERCISE MECHANICS'.

TREATMENT OF OPTIONS AND SHARES UPON RESIGNATION OR TERMINATION OF EMPLOYMENT

     The options held by an officer who voluntarily leaves the Company prior to
     age 60 (other than due to death or Disability), is terminated by the
     Company at any time other than for Cause (as defined in the existing option
     plans and agreements) or becomes a part-time employee would continue to be
     exercisable during exercise periods in accordance with their existing
     terms.

     To the extent that a regularly scheduled exercise period would not occur
     during such 90-day period, the former officer would be permitted to deliver
     an exercise notice during a special individual exercise period beginning 5
     days prior to the date on which the options would expire and ending on the
     last day of the 90-day period (i.e., the former officer would be permitted
     to exercise during the last five days the option is outstanding). An
     exercise notice would become effective immediately unless the conditions to
     exercise set forth under 'EXERCISE MECHANICS' would not be satisfied on the
     date of delivery, in which case the exercise notice would become effective
     on the first date on which those conditions would be satisfied.

     A former officer would be required to wait a minimum of six months after
     the date of exercise before being permitted to put shares received on that
     exercise. As a result, a former officer could be required to wait until the
     put period in the year following option exercise before being able to put
     shares. For example, an officer who leaves on July 1, 2002 would only be
     able to exercise his or her options from September 23-28, 2002. This former
     officer would not be permitted to deliver a put notice until at least 5
     months after the date of exercise (i.e., not earlier than February 23,
     2003) which is after the end of the period for delivery of put notices.
     Therefore, the officer would not be permitted to deliver a put notice until
     November 15, 2003.

     This put right would expire at the end of the first put period following
     termination of employment during which the former officer is permitted to
     put his or her shares.

     The options and put rights of any officer who is terminated for Cause would
     terminate immediately upon termination.

     The Company would offer loans to former officers who resign or are
     terminated other than for Cause on terms consistent with those set forth
     above under the heading 'EXERCISE MECHANICS', except that in the case of
     former officers that resign, the maximum amount of the loan will equal the
     exercise price of the options being exercised (i.e., it would not cover
     taxes).

     The Company would have a call right (which would become exercisable upon
     the former officer's termination of full-time employment) over the former
     officer's shares at the then-current valuation price and the officer's
     options at a price equal to the spread.

TREATMENT OF OPTIONS AND SHARES UPON DEATH

     Upon the death of an officer, the officer's estate would have the right to
     immediately exercise all the officer's options subject to satisfaction of
     the conditions to exercise set forth above under 'EXERCISE MECHANICS'. As
     provided in the existing option plans and agreements, the estate of a
     former officer who dies after termination of employment would have the
     exercise period

                                      A-27

<Page>
     specified with respect to such termination (e.g., 90 days to exercise
     following termination other than for Cause).

     Upon the death of an officer or a former officer, the estate would have the
     right to put the officer's shares immediately at the then-current valuation
     price. This put right would expire on the first anniversary of the date of
     death. A put notice in the case of the death of an officer would become
     effective 5 business days after the date the notice is delivered by the
     officer's estate.

     The Company would have an immediately exercisable call over the officer's
     shares at the then-current valuation price and the officer's options at a
     price equal to the spread.

FUTURE PUBLIC OFFERING OF THE COMPANY

     If there is ever a future public offering of common stock, the exercise
     limitations and put rights would expire immediately prior to its completion
     (because there would then be a public market for the shares of the
     Company's stock).

CERTAIN TAX CONSIDERATIONS

    The following is a general summary of the material federal income tax
consequences to optionholders under current law. This summary deals with the
general tax principles that apply and is provided only for general information.
Some kinds of taxes, such as foreign, state and local income taxes, are not
discussed. Tax laws are complex and subject to change and may vary depending on
individual circumstances and from locality to locality. This summary does not
discuss all aspects of income taxation that may be relevant to an optionholder
in light of his or her personal investment circumstances. This summarized tax
information is not tax advice.

    OPTIONHOLDERS ARE ADVISED TO CONSULT THEIR OWN ADVISOR AS TO THE SPECIFIC
TAX CONSEQUENCES OF THE PROPOSED MODIFICATIONS.

INCENTIVE STOCK OPTIONS:

     The grant or exercise of an option which is an ISO does not result in
     taxable income to the optionholder or a deduction to the Company. However,
     the excess of the fair market value on the date of exercise of the shares
     acquired over the option exercise price will generally be included in
     alternative minimum taxable income. Whether an optionholder is subject to
     the alternative minimum tax will depend on such the optionholder's other
     taxable income.

     If an optionholder does not dispose of shares acquired pursuant to an ISO
     before the later of two years from the date of grant of such option and one
     year after the date of exercise of an ISO, any gain or loss realized on a
     subsequent disposition of such shares will be treated as a long-term
     capital gain or loss. If, however, an optionholder disposes of shares
     acquired pursuant to an ISO before the expiration of the one-year and
     two-year periods described above (a 'DISQUALIFYING DISPOSITION'), an amount
     equal to the excess of the fair market value of the shares at the time of
     the option's exercise (or the proceeds of the disposition, if less) over
     the option price will, in the year of disposition, be taxable to the
     optionholder as ordinary income and deductible by the Company. If the
     shares are disposed of at a loss, the loss will be a capital loss.

     An optionholder's basis for capital gains purposes in shares acquired
     pursuant the exercise of an ISO will be the amount paid by the optionholder
     upon exercise of the option. However, in the event of a disqualifying
     disposition, the optionholder's basis in the shares is increased by an
     amount equal to the amount taxable to the optionholder as ordinary income.

NONQUALIFIED STOCK OPTIONS:

     Upon exercise of an option which does not qualify as an ISO (a
     'NONQUALIFIED STOCK OPTION'), an amount equal to the excess of the fair
     market value of the shares acquired on the date of exercise of such option
     over the option exercise price is taxable to the optionholder as ordinary
     income (which would be subject to withholding) and deductible to the
     Company. The optionholder's

                                      A-28

<Page>
     basis for capital gains purposes in the shares acquired is equal to the sum
     of the exercise price and the amount taxable as ordinary income. Gain or
     loss on a subsequent disposition of shares acquired pursuant to a
     nonqualified stock option will be treated as capital gain or loss, and will
     be long-term capital gain or loss if such shares were held for more than
     one year after the date of exercise.

EXERCISE OF OPTIONS WITH PREVIOUSLY ACQUIRED SHARES:

     If an optionholder uses previously acquired shares to pay all or a portion
     of the option price on the exercise of an option (whether or not an ISO),
     no gain or loss would be recognized with respect to the previously acquired
     shares. The shares received upon exercise of the option, to the extent of
     the number of previously acquired shares exchanged therefor, will have the
     same basis and holding period for capital gain purposes as the previously
     acquired shares.

     If the option is a nonqualified stock option, the additional shares
     received have a basis equal to the sum of the cash paid on exercise and the
     ordinary income taxable to the optionholder as a result of the exercise. If
     the option is an ISO, the additional shares have a basis equal to the cash
     paid on exercise (plus, if the one-year and two-year periods discussed
     above have not been met with respect to shares acquired upon the previous
     exercise of an ISO, the amount includable in income.)

     The use of shares previously acquired by exercising an ISO in satisfaction
     of all or part of the exercise price for another option (whether or not an
     ISO) is a disposition of the previously acquired shares for purposes of
     determining whether it is a disqualifying disposition (i.e., whether the
     holding periods described above have been complied with). All shares
     acquired upon the exercise of an ISO, including the previously acquired
     shares, are considered to have been acquired upon the date of exercise for
     purposes of these holding periods.

PROPOSED MODIFICATIONS:

     Although not free from doubt, the provision of the put rights described
     above should not cause options intended to qualify as ISOs to fail to be so
     qualified. If the IRS were to conclude that the options no longer qualify
     as ISOs, the options would be subject to the treatment applicable to
     nonqualified stock options.

     If the aggregate fair market value of the shares underlying ISOs
     (determined as of the date of grant) that are exercisable for the first
     time during any calendar year exceeds $100,000, options covering shares
     equal to that excess will be treated as nonqualified stock options. Thus,
     the acceleration of vesting and exercisability upon the approval of the
     proposed transaction may cause some options that currently qualify as ISOs
     to be treated as nonqualified stock options.

     The deductibility of interest paid under the employee loan would be
     determined based on the facts and circumstances of the particular
     optionholder. OPTIONHOLDERS SHOULD CONSULT THEIR OWN ADVISOR AS TO THE
     SPECIFIC RULES GOVERNING THE DEDUCTIBILITY OF THIS INTEREST IN LIGHT OF
     THEIR OWN PARTICULAR TAX SITUATION.

     Cancelation of options in exchange for a cash payment would result in the
     optionholder's realization of ordinary income (which would be subject to
     withholding) in an amount equal to the cash payment received.

Agreement. ILFC hereby further affirms that this irrevocable proxy is coupled
with an interest and may under no circumstances be revoked. ILFC hereby ratifies
and confirms all that such irrevocable proxy may lawfully do or cause to be done

    SECTION 5. Purchase of Shares. (a) ILFC shall sell, transfer and assign to
the Company, and the Company shall purchase from ILFC, such number of shares of

hereinafter referred to as the 'PURCHASE SHARES'), at the ILFC Purchase Closing
(as defined below) for aggregate consideration consisting of a senior unsecured
note of the Company due January 15, 2002 (the 'ILFC NOTE'), in an aggregate
principal amount equal to the ILFC Purchase Price (as defined below) and bearing

The 'ILFC PURCHASE PRICE' shall equal the product of (i) the number of shares of
Common Stock into which the Purchase Shares would be convertible at the
Conversion Price in effect at the time of the ILFC Purchase Closing (as
determined in accordance with the Amendment but disregarding Section 6(c)

the Existing Agreement.

    (c) Interpretation. When a reference is made in this Agreement to Sections,
such reference shall be to a Section to this Agreement unless otherwise

this Agreement, they shall be deemed to be followed by the words 'without

    (d) Severability. If any term or other provision of this Agreement is

policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that transactions contemplated hereby are fulfilled to the extent possible.

    (e) Counterparts. This Agreement may be executed in one or more

Existing Agreement constitutes the entire agreement and supersedes all prior

obligations under this Agreement shall be assigned, in whole or in part, by
operation of law or otherwise, by the Company without the prior written consent
of ILFC or by ILFC without the prior written consent of the Company, and any
purported assignment without such consent shall be void. Subject to the
preceding sentences, this Agreement will be binding upon, inure to the benefit
of, and be enforceable by, the parties and their respective successors and
assigns.

    (i) Enforcement. The parties agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or

                                      B-4

<Page>
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any New York state court or any
Federal court located in the State of New York, this being in addition to any
other remedy to which they are entitled at law or in equity. In addition, each
of the parties hereto (i) consents to submit itself to the personal jurisdiction
of any New York state court or any Federal court located in the State of New
York in the event any dispute arises out of this Agreement or any transaction
contemplated by this Agreement, (ii) agrees that it will not attempt to deny or
defeat such personal jurisdiction by motion or other request for leave from any

York and (iv) waives any right to trial by jury with respect to any claim or
proceeding related to or arising out of this Agreement or any transaction
contemplated hereby.

    IN WITNESS WHEREOF, each party has duly executed this Agreement, all as of
the date first written above.

    3. Dividends. The holders of Series B Preferred Stock shall be entitled to
receive, when and if declared by the Board of Directors, but only out of funds
legally available therefor, cumulative cash dividends at the annual rate of 5.0%
of the Liquidation Amount (as defined below) (the 'DIVIDEND RATE') per share,
and no more, payable quarterly in equal amounts of 1.25% of the Liquidation
Amount on the 15th day of December, March, June and September, respectively, in
each year (or if any such date is not a business day, on the next succeeding
business day) commencing on December 15, 2000, with respect to the quarterly
dividend period (or portion thereof) ending on the day preceding such respective
dividend payment date, to holders of record on the respective date, not more
than 60 nor less than ten days preceding such dividend payment date, fixed for
such purpose by the Board of Directors in advance of payment of each particular
dividend. The Dividend Rate shall increase to 5.66% per annum effective on the
date the Transaction is consummated (the 'TRANSACTION EFFECTIVE DATE') and shall
further increase to 6.5% per annum on the date which is the fourth anniversary
of the Transaction Effective Date; provided, however, that from and after the
date on which a Public Offering is consummated the Dividend Rate shall be 5.0%
per annum. If the Corporation fails to pay any quarterly dividend and such
failure is not cured within ten days of the date on which the dividend was
payable, whether or not the funds are legally available therefor, the Dividend
Rate shall increase as follows: (i) if the Corporation has issued on or prior to
December 31, 2000, any series of Series A Preferred Stock, the Dividend Rate
shall increase to the highest rate of interest per annum payable on any such
series of Series A Preferred Stock issued and outstanding on such date, and
(ii) if the Corporation has not issued on or before December 31, 2000, any
series of Series A Preferred Stock, the Dividend Rate shall increase to 9.8% per
annum. Following the payment of all accrued and unpaid dividends that have
become due and payable, the Dividend Rate will revert to the Dividend Rate that
otherwise would have been in effect on such date. Dividends shall accrue daily
and shall be payable on the Series B Preferred Stock for any period shorter than
a full quarterly period shall be computed on the basis of a 360-day year
consisting of twelve 30-day months. Dividends on shares of Series B Preferred
Stock shall be cumulative from the last dividend payment date, or if no
dividends have been paid on the outstanding shares of Series B Preferred Stock,
from the date of issuance, whether or not the Corporation has the funds legally
available therefor. Accumulations of dividends on outstanding shares of
Series B Preferred Stock shall bear interest at the rate of 9.5% per annum.

    So long as any shares of Series B Preferred Stock remain outstanding, the
Corporation may not pay or declare any dividend, nor make any distribution on
any Junior Stock, other than a dividend payable

                                      B-7

<Page>
solely in Junior Stock, and shall not purchase, redeem or otherwise acquire for
consideration, directly or indirectly (other than as a result of a
reclassification of Junior Stock into Junior Stock, or the exchange or
conversion of one share of Junior Stock for or into another share of Junior
Stock, and other than through the use of the proceeds of a substantially
contemporaneous sale of other shares of Junior Stock), unless (i) all accrued
and unpaid dividends (including any interest thereon) on all outstanding shares
of Series B Preferred Stock have been paid in full and the full dividend thereon
for the then current quarterly dividend period shall have been paid or declared
and set apart for payment and (ii) all prior redemption requirements with
respect to Series B Preferred Stock shall have been complied with. When
dividends are not paid in full upon the Series B Preferred Stock and any Parity
Stock, all dividends declared upon shares of Series B Preferred Stock and all
Parity Stock shall be declared pro rata so that the amount of dividends declared
per share on the Series B Preferred Stock and all such Parity Stock shall in all
cases bear to each other the same ratio that accrued dividends per share on the
shares of Series B Preferred Stock and all such Parity Stock bear to each other.
Subject to the foregoing, and not otherwise, such dividends (payable in cash,
stock or otherwise) as may be determined by the Board of Directors may be
declared and paid on any Junior Stock from time to time out of any funds legally
available therefor, and the Series B Preferred Stock shall not be entitled to
participate therein.

    4. Liquidation Rights.

    (a) In the event of any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary (any such event being a
'LIQUIDATION TRANSACTION') the Series B Preferred Stock shall rank prior to any
shares of Junior Stock, so that in the event of any Liquidation Transaction,
whether voluntary or involuntary, the holders of Series B Preferred Stock shall
be entitled to receive out of the assets of the Corporation available for
distribution to its stockholders, whether from capital, surplus or earnings,
before any distribution is made to holders of Junior Stock, an amount per share
equal to $100,000 per share (the 'LIQUIDATION AMOUNT') for each outstanding
share of Series B Preferred Stock, plus an amount equal to all accrued and
unpaid dividends (including any interest thereon) (such sum being referred to as
the 'LIQUIDATION PREFERENCE' for the Series B Preferred Stock).

    (b) If, upon any Liquidation Transaction, the assets of the Corporation, or
proceeds thereof, shall be insufficient to pay the full Liquidation Preference
to all holders of the Series B Preferred Stock, then such assets, or the
proceeds thereof, shall be divided and distributed pro rata among the holders of
the Series B Preferred Stock and the holders of any Parity Stock in accordance
with the aggregate respective liquidation preferences of the Series B Preferred
Stock and all such Parity Stock.

    (c) After payment shall have been made in full to all holders of Series B
Preferred Stock, as provided in this Section 4, the holders of the Junior Stock
shall, subject to the respective terms and provisions applying thereto, be
entitled to receive any and all assets remaining to be paid or distributed, and
the holders of the shares of Series B Preferred Stock shall not be entitled to
share therein.

    5. Redemption and Repurchase.

    (a) Change of Control.

    (i) Optional Redemption by the Corporation. If, on or before the third
anniversary of the initial issuance of the Series B Preferred Stock, any person
(other than J. George Mikelsons or any person or entity controlled by him)
acquires or enters into an agreement with the Corporation to acquire capital
stock of the Corporation representing a majority of the voting power represented
by all outstanding capital stock of the Corporation (such event being referred
to as a 'CHANGE OF CONTROL'), the Corporation may redeem for cash, in whole at
any time, all shares of Series B Preferred Stock at the time outstanding, upon
notice given as hereinafter specified within 30 days following a Change of
Control, at a redemption price per share equal to the sum of (i) the Liquidation
Amount, (ii) all accrued and unpaid dividends (including any interest thereon)
to the date of redemption, (iii) a premium equal to 9.5% per annum of the
Liquidation Amount calculated from the date of issuance of the shares of
Series B Preferred Stock to the date of redemption and (iv) an additional
premium equal to the product of (x) the number of shares into which the
outstanding shares of Series B Preferred Stock are convertible at the Conversion
Price in effect on the date of such repurchase and (y) the Transaction Spread.

                                      B-8

<Page>
    (ii) Mandatory Repurchase at the Option of the Holder. If a Change of
Control occurs on or before the third anniversary of the initial issuance of the
Series B Preferred Stock, all but not less than all of the holders of Series B
Preferred Stock may require the Corporation to repurchase for cash, in whole at
any time, all shares of Series B Preferred Stock at the time outstanding, upon
notice given as hereinafter specified within 45 days following a Change of
Control, at a purchase price ('REPURCHASE PRICE') per share equal to the sum of
(i) the Liquidation Amount, (ii) all accrued and unpaid dividends (including any
interest thereon) to the date of repurchase, (iii) a premium equal to the
difference between (x) the amount obtained when the highest dividend rate per
annum payable on any series of Series A Preferred Stock issued and outstanding
on the date of repurchase is multiplied by the Liquidation Amount calculated
from the date of issuance of the shares of Series B Preferred Stock to the date
of repurchase and (y) 5% per annum of the Liquidation Amount calculated from the
date of issuance of the shares of Series B Preferred Stock to the date of
repurchase and (iv) an additional premium equal to the product of (x) the number
of shares into which the outstanding shares of Series B Preferred Stock are
convertible at the Conversion Price in effect on the date of such repurchase and
(y) the Transaction Spread. A notice of mandatory repurchase under this Section
5(a)(ii) (a 'REPURCHASE NOTICE') may be given to the Corporation at any time
within the 45 days following a Change of Control, by all but not less than all
of the holders of Series B Preferred Stock. To be valid, a Repurchase Notice
must (i) specify a date of repurchase (the 'REPURCHASE DATE') that is a business
day not earlier than 45 days following the date of receipt by the Corporation of
the Repurchase Notice, (ii) be signed by all registered holders of Series B
Preferred Stock and (iii) be delivered to the Corporation at its corporate
headquarters to the attention of its Corporate Secretary by first class mail,
overnight courier or by hand. Once given, a Repurchase Notice will be
irrevocable. On and after the Repurchase Date, the sole right of the holders of
Series B Preferred Stock shall be to receive the Repurchase Price without
interest against delivery of certificates representing Series B Preferred Stock.

    (b) Optional Redemption. On or after the third anniversary of the initial
issuance of the Series B Preferred Stock, the Corporation may redeem for cash,
in whole at any time, or in part from time to time, the shares of Series B
Preferred Stock at the time outstanding, upon notice given as hereinafter
specified, at the redemption price in effect at the redemption date as provided
in this Section 5. If redeemed during the 12-month period commencing on the
anniversary date of the initial issuance of Series B Preferred Stock in the
years set forth below the redemption price shall be the Liquidation Amount plus
all accrued and unpaid dividends (including any interest thereon) to the date of
redemption plus (i) a premium (expressed as a percentage of the Liquidation
Amount) as follows:

<Table>

</Table>

    (ii) an additional premium equal to the product of (x) the number of shares
into which the outstanding shares of Series B Preferred Stock to be redeemed are
convertible at the Conversion Price in effect on the date of such optional
redemption date and (y) the Transaction Spread.

    (c) Mandatory Redemption. The Corporation shall redeem any outstanding
shares of Series B Preferred Stock on the anniversary of the initial issuance of
the Series B Preferred Stock in 2015 for an amount in cash equal to the
Liquidation Amount plus all accrued and unpaid dividends (including any interest
thereon).

                                      B-9

<Page>
    (d) Notice of Redemption. So long as the Series B Preferred Stock is not
registered under the Securities Act of 1933, as amended (the 'SECURITIES ACT'),
notice of every redemption of Series B Preferred Stock shall be mailed by first
class mail, postage prepaid, addressed to the holders of record of the shares to
be redeemed at their respective last addresses as they appear on the books of
the Corporation. If the Corporation registers the outstanding shares of
Series B Preferred Stock under the Securities Act, then such notice shall be
made by mail as described in the preceding sentence and, the Corporation shall
also publish any notice of redemption by means of the Dow Jones News Service or
such other similar news wire service or newspaper. Such mailing and any such
publication shall be at least ten days and not more than 45 days prior to the
date fixed for redemption. Any notice that is mailed or published, as the case
may be, in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the shareholder receives such notice.
Furthermore, the validity of the proceedings for the redemption of any shares of
Series B Preferred Stock of any shareholder shall not be affected by any defect
in any notice given to any other shareholder. Such notice shall set forth

    (A) the time and date for the redemption;

    (B) the number of shares to be redeemed and if less than all shares of
Series B Preferred Stock held by a holder are to be redeemed, the number of such
holder's shares to be redeemed;

    (C) the redemption price;

    (D) the place or places where certificates for the shares are to be
surrendered for redemption;

    (E) that dividends on the shares to be redeemed will cease to accrue on the
redemption date (unless the Corporation shall default in redeeming the shares on
the redemption date); and

    (F) that the right to convert such shares shall terminate at the close of
business on the redemption date.

    (e) Redemptions in Part. In case of any redemption of only a part of the
shares of Series B Preferred Stock at the time outstanding, the redemption may
be pro rata, by lot or by any other method as may be determined by the Board of
Directors in its sole discretion to be equitable as set forth in a certificate
of the Secretary or Assistant Secretary of the Corporation filed with the
transfer agent or agents for the Series B Preferred Stock. The Board of
Directors shall have full power and authority, subject to the provisions herein
contained, to prescribe the terms and conditions upon which Series B Preferred
Stock shall be redeemed from time to time.

    (f) Effect of Redemption. If notice of redemption shall have been duly
given, and if on or before the redemption date specified therein all funds
necessary for such redemptions shall have been set aside by the Corporation,
separate and apart from its other funds, in trust for the pro rata benefit of
the holders of the shares called for redemption, so as to be and continue to be
available therefor, then, notwithstanding that any certificate for shares so
called for redemption shall not have been surrendered for cancelation, on and
after such redemption date, all shares so called for redemption shall no longer
be deemed outstanding and all rights with respect to such shares shall forthwith
on such redemption date cease and terminate, except only the right of the
holders thereof to receive the amount payable on redemption thereof, without
interest. Any funds so deposited and unclaimed at the end of two years from such
redemption date shall, to the extent permitted by law, be released or repaid to
the Corporation, after which time the holders of the shares so called for
redemption shall look only to the Corporation for payment thereof. A holder of
shares of Series B Preferred Stock called for redemption shall be entitled to
convert such shares in accordance with the provisions of Section 6 up until the
close of business on the redemption date.

    Any funds so deposited or set aside by the Corporation which shall not be
required for such redemption because of the exercise of any right of conversion
set forth in Section 6 below subsequent to the date of such deposit shall be
released or repaid to the Corporation forthwith.

    6. Conversion. The holders of the Series B Preferred Stock shall have
conversion rights as follows:

    (a) Right to Convert. On the terms and subject to the conditions of this
Section 6, the holder of a share of Series B Preferred Stock shall have the
right, at its option, at any time to convert such share into that number of
shares of fully paid and non-assessable Common Stock (calculated as to each

                                      B-10

<Page>
conversion to the nearest 1/100th of a share) obtained by dividing the
Liquidation Amount, by the Conversion Price (as defined in Section 6(d)) and by
surrender of such share pursuant to Section 6(b). The shares of Common Stock
issuable upon such conversion are hereinafter referred to as the 'CONVERSION
SHARES'. No payment or adjustment shall be made upon any conversion on account
of any dividends accrued on the shares of Series B Preferred Stock surrendered
for conversion or on account of any dividends on the Common Stock issued upon
conversion for which the record date is on or prior to the conversion date.

    Holders of shares of Series B Preferred Stock at the close of business on a
record date for any payment of declared dividends shall be entitled to receive
the dividend payable on such shares on the corresponding dividend payment date
notwithstanding the optional conversion of such shares following such record
date and prior to the corresponding dividend payment date.

    (b) Conversion Procedures. In order to exercise the conversion privilege,
the holder of any shares of the Series B Preferred Stock shall surrender the
certificate representing such shares at the principal office of the Corporation,
with a written notice stating that such holder elects to convert all or a
specified whole number of such shares pursuant to this Section 6 and specifying
the name or names in which such holder wishes the certificate or certificates
for Conversion Shares to be issued. Unless the Conversion Shares are to be
issued in the same name as the name in which such shares of Series B Preferred
Stock are registered, the certificate representing the shares surrendered for
conversion shall be accompanied by instruments of transfer, in form satisfactory
to the Corporation, duly executed by the holder or its duly authorized attorney.
As promptly as practicable after such surrender of a certificate for shares of
the Series B Preferred Stock to be converted, and in any event within five
business days thereafter, the Corporation shall issue and deliver at such office
to such holder, or on such holder's written order, (i) a certificate or
certificates for the applicable number of full Conversion Shares, (ii) if less
than the full number of shares of Series B Preferred Stock evidenced by the
surrendered certificate is being converted, a new certificate, of like tenor,
for the number of shares of Series B Preferred Stock evidenced by such
surrendered certificate less the number of shares being converted and (iii) the
cash payment in settlement of any fractional Conversion Share as provided in
Section 6(c). Upon conversion of any shares of Series B Preferred Stock, the
holder thereof shall be entitled to receive an amount equal to all declared and
unpaid dividends on such shares.

    In the case of the exercise of the conversion privilege under Section 6(a),
each conversion shall be deemed to have been effected immediately after the
close of business on the date on which the certificate for shares of Series B
Preferred Stock to be converted is surrendered and such notice is received by
the Corporation as aforesaid, and the person or persons in whose name or names
any certificate or certificates for Conversion Shares are issuable shall be
deemed to have become the holder or holders of record of such Conversion Shares
at such time on such date and such conversion shall be at the applicable
Conversion Price in effect at such time on such date, unless the stock transfer
books of the Corporation are closed on that date, in which event such person or
persons shall be deemed to have become such holder or holders of record at the
close of business on the next day on which such stock transfer books are open
(provided that if such books shall remain closed for five days, such fifth day
shall be the date any such person shall become such a holder), but such
conversion shall be at the Conversion Price in effect on the date on which such
certificate was surrendered and such notice was received. Upon delivery, all
Conversion Shares shall be duly authorized, validly issued, fully paid, non-
assessable, free of all liens and charges and not subject to any preemptive or
subscription rights.

    (c) Settlement of Fractional Conversion Shares. No fractional Conversion
Shares or scrip representing fractions of Conversion Shares shall be issued upon
conversion of shares of the Series B Preferred Stock. Instead of any fractional
Conversion Share otherwise deliverable, the Corporation shall pay to the holder
of the converted shares an amount in cash equal to the Current Market Price (as
defined below) or, if shares of Common Stock are not authorized for quotation on
the Nasdaq National Market System (the 'NASDAQ') and no Current Market Price can
be determined on such date pursuant to the methods specified in Section 6(e),
the Valuation Price (as defined in Section 9) of such fractional Conversion
Share on the date of conversion. If more than one share is surrendered for
conversion at one time by the same holder, the number of full Conversion Shares
shall be computed on the basis of the aggregate number of shares so surrendered.
The 'CURRENT MARKET PRICE' per share of

                                      B-11

<Page>
Common Stock on any day is the average of the high and low sales prices of the
Corporation's Common Stock on the NASDAQ for the 10 consecutive trading days
preceding such day rounded up to the nearest whole cent. A 'TRADING DAY' is a
day on which the principal national securities exchange on which the Common
Stock is listed or admitted to trading is open for the transaction of business
or, if the Common Stock is not then listed or admitted to trading on any
national securities exchange, any day other than Saturday, Sunday or a federal
holiday.

    (d) The 'CONVERSION PRICE' shall be $15.67 and may be adjusted from time to
time pursuant to this Section 6(d). The Conversion Price shall be adjusted from
time to time as follows:

    (i) If, after the date of initial issuance of the Series B Preferred Stock,
the Corporation (A) pays a dividend or makes a distribution on the Common Stock
in shares of Common Stock, (B) subdivides or combines its outstanding shares of
Common Stock into a greater or smaller number of shares or (C) issues by
reclassification of the Common Stock any shares of capital stock of the
Corporation, the Conversion Price in effect immediately prior to such action
shall be adjusted so that the holder of any share of Series B Preferred Stock
thereafter surrendered for conversion shall be entitled to receive, at the time
of such conversion, the number of shares of Common Stock or other capital stock
of the Corporation that it would have owned or been entitled to receive
immediately following such action had such share been converted immediately
prior to such action or the record date therefor, whichever is earlier. Such
adjustment shall become effective immediately after the record date, in the case
of a dividend or distribution, or immediately after the effective date, in the
case of a subdivision, combination or reclassification.

    (ii) If, after the date of initial issuance of the Series B Preferred Stock,
the Corporation issues any Additional Shares (as defined below) for a
consideration per share below (x) the closing price as of 4:30 pm on the
principal market on which the Common Stock is traded on the trading day
immediately prior to the date on which the Corporation shall have agreed to such
issuance or (y) if shares of Common Stock are not traded on any national
securities exchange or authorized for quotation on the Nasdaq Stock Market, the
Valuation Price on the trading day immediately prior to the date on which the
Corporation shall have agreed to such issuance (with the price determined under
clause (x) or (y), as applicable, being referred to as the 'CLOSING PRICE'),
then in each case the Conversion Price shall be adjusted by multiplying the
Conversion Price in effect immediately prior to such issuance by a fraction,

    (A) the numerator of which shall be the number of shares of Common Stock and
Share Equivalents (as defined below) outstanding immediately prior to the
issuance of such Additional Shares plus the number of shares of Common Stock
that the aggregate consideration for such Additional Shares would purchase at a
consideration per share equal to such Closing Price, and

    (B) the denominator of which shall be the number of shares of Common Stock
and Share Equivalents outstanding immediately prior to the issuance of such
Additional Shares plus the number of Additional Shares so issued.

Such adjustment for the Series B Preferred Stock shall become effective
immediately after the issuance of such Additional Shares.

    'ADDITIONAL SHARES' shall mean any shares of Common Stock of the Corporation
issued by the Corporation after the date of issuance of the Series B Preferred
Stock excluding Permitted Issuances. 'SHARE EQUIVALENTS' shall mean the Common
Stock deliverable upon conversion or exercise of all outstanding Series B
Preferred Stock, convertible securities, options, warrants and rights of the
Corporation as of the date such computation is made and as of the time such
computation is effective as specified herein.

    'PERMITTED ISSUANCES' shall mean:

    (A) any stock options which have been granted and remain unexercised as of
the date of issuance of the Series B Preferred Stock, which shall include any
such stock options the terms of which have been modified in connection with the
Transaction;

    (B) stock options granted and shares issued to employees, directors and
consultants after the issuance of the Series B Preferred Stock in the aggregate
amount of 500,000 shares (which number shall be appropriately adjusted to
reflect any stock splits, combinations or recapitalizations) of Common

                                      B-12

<Page>
Stock per annum (commencing with the year 2000) pursuant to the Corporation's
stock plans, provided that if the aggregate number of stock options granted per
annum pursuant to the Corporation's stock plans is less than 500,000, 'Permitted
Issuances' shall include that number of stock options equal to the difference
between 500,000 and the actual number of stock options granted per annum
pursuant to the Corporation's stock plans, which stock options of Common Stock
may be granted in subsequent years;

    (C) additional options granted and shares issued in an amount equal to
options granted and shares issued pursuant to the foregoing clauses (A) and (B)
to the extent such shares are returned to the Corporation's stock plans upon the
lapse of unexercised stock options or the repurchase (at original purchase
price) of unvested shares;

    (D) any shares issued upon exercise of options granted pursuant to the
foregoing clauses (A)-(C) including as a result of the operation of anti
dilution adjustments provided for therein;

    (E) any shares issued pursuant to employee stock purchase, savings or
ownership plans, including all shares issued to a trust formed in respect
thereof;

    (F) any shares issued upon conversion of the Series B Preferred Stock
(including adjustments to the conversion ratio), any stock options granted and
shares issued upon the exercise thereof approved by the holders of a majority of
the Series B Preferred Stock, and any shares issued to the holders of the Series
B Preferred Stock in connection with any contractual rights related to such
approved shares or options; and

    (G) any shares issued pursuant to the exercise, conversion or exchange of
other securities.

    (iii) If after the date of initial issuance of the Series B Preferred Stock
the Corporation issues any warrants, options or other rights entitling the
holders thereof to subscribe for or purchase either any Additional Shares or
evidences of debt, shares of capital stock or other securities that are
convertible into or exchangeable for, with or without payment of additional
consideration, Additional Shares (such warrants, options or other rights being
called 'RIGHTS' and such convertible or exchangeable evidences of debt, shares
of capital stock or other securities being called 'CONVERTIBLE SECURITIES'), and
the consideration per share for which Additional Shares may at any time
thereafter be issuable pursuant to such Rights or Convertible Securities (when
added to the consideration per share of Common Stock, if any, received for such
Rights or Convertible Securities) is less than the Conversion Price then in
effect, the Conversion Price shall be adjusted as provided in Section 6(d)(ii)
on the basis that,

    (A) the maximum number of Additional Shares issuable pursuant to all such
Rights or necessary to effect the conversion or exchange of all such Convertible
Securities shall be deemed to have been issued, and

    (B) the aggregate consideration (plus the consideration, if any, received
for such Rights and Convertible Securities) for such maximum number of
Additional Shares shall be deemed to be the consideration received and
receivable by the Corporation for the issuance of such Additional Shares
pursuant to such Rights or Convertible Securities.

    No adjustment of the Conversion Price shall be made under this Section
6(d)(iii) upon (x) the issuance of any Convertible Securities issued pursuant to
the exercise of any Rights, to the extent that such adjustment was previously
made upon the issuance of such Rights pursuant to Section 6(d)(iii) or (y) the
granting of any stock options that qualify as Permitted Issuances under clause
(B) or (C) of the definition thereof.

    (iv) For purposes of Section 6(d)(iii), the relevant Conversion Price shall
be the Conversion Price in effect immediately prior to the earlier of (A) the
record date for the holders of Common Stock entitled to receive the Rights or
Convertible Securities and (B) the initial issuance of the Rights or Convertible
Securities, and the adjustment provided for in either such Section shall become
effective immediately after the earlier of the times specified in clauses (A)
and (B).

    (v) No adjustment of the Conversion Price shall be made under Section
6(d)(ii) upon the issuance of any Additional Shares pursuant to the exercise of
any Rights or any conversion or exchange rights pursuant to any Convertible
Securities, if such adjustment was previously made in connection with the
issuance of such Rights or Convertible Securities (or in connection with the
issuance of any Rights therefor) pursuant to Section 6(d)(iii).

                                      B-13

<Page>
    (vi) If any Rights or Convertible Securities (or any portions thereof) that
gave rise to an adjustment pursuant to Section 6(d)(iii) expire or terminate
without the exercise thereof and/or if by reason of the provisions of such
Rights or Convertible Securities there has been any increase, with the passage
of time or otherwise, in the consideration payable upon the exercise thereof,
the Conversion Price shall be readjusted (but to no greater extent than
originally adjusted) on the basis of,

    (A) eliminating from the computation Additional Shares corresponding to such
expired or terminated Rights or conversion or exchange rights,

    (B) treating the Additional Shares, if any, actually issued or issuable
pursuant to the previous exercise of such Rights or conversion or exchange
rights as having been issued for the consideration actually received and
receivable therefor, and

    (C) treating any such Rights or conversion or exchange rights that remain
outstanding as being subject to exercise on the basis of the consideration
payable upon the exercise or conversion thereof as is in effect at such time,

provided, however, that any consideration actually received by the Corporation
in connection with the issuance of such Rights shall form part of the
readjustment computation even though such Rights expired without being
exercised. The Conversion Price shall be adjusted as provided in Section
6(d)(ii) and any applicable provisions of Section 6(d)(iii) as a result of any
increase in the number of Additional Shares issuable, or any decrease in the
consideration payable upon any issuance of Additional Shares, pursuant to any
anti dilution provisions of any Rights or Convertible Securities.

    (vii) (A) If any Additional Shares, Convertible Securities or Rights are
issued for cash, the consideration received therefor shall be deemed to be the
amount of cash received.

    (B) If any Additional Shares, Convertible Securities or Rights are offered
by the Corporation for subscription, the consideration received therefor shall
be deemed to be the subscription price.

    (C) If any Additional Shares, Convertible Securities or Rights are sold to
underwriters or dealers for public offering without a subscription offering, the
consideration received therefor shall be deemed to be the public offering price.

    (D) In any case covered by Section 6(d)(vii) (A), (B) or (C), in determining
the amount of any consideration received by the Corporation in whole or in part
other than in cash, the amount of such consideration shall be deemed to be the
fair market value of such consideration as determined in good faith by the Board
of Directors, and evidence of such determination shall be filed with the minutes
of the Corporation. If Additional Shares are issued as part of a unit with
Rights, the consideration received for the Rights shall be deemed to be the
portion of the consideration received for such unit determined in good faith at
the time of issuance by the Board of Directors, and evidence of such
determination shall be filed with the minutes of the Corporation. If the Board
of Directors does not make any such determination, the consideration received
for the Rights shall be deemed to be zero. In either event, the consideration
received for the Additional Shares shall be deemed to be the consideration
received for such unit less the consideration deemed to have been received for
the Rights.

    (E) In any case covered by Section 6(d)(vii) (A), (B), (C) or (D), in
determining the amount of consideration received by the Corporation, (I) any
amounts received or receivable for accrued interest or accrued dividends shall
be excluded and (II) any compensation, underwriting commissions or concessions
or expenses paid or incurred in connection therewith shall not be deducted.

    (F) In any case covered by Section 6(d)(vii) (A), (B), (C) or (D), there
shall be added to the consideration received by the Corporation at the time of
issuance or sale (I) the minimum aggregate amount of additional consideration
payable to the Corporation upon the exercise of Rights that relate to
Convertible Securities and (II) the minimum aggregate amount of consideration
payable upon the conversion or exchange thereof.

    (G) If any Additional Shares, Convertible Securities or Rights are issued in
connection with any merger, consolidation or other reorganization in which the
Corporation is the surviving corporation, the amount of consideration received
therefor shall be deemed to be the fair market value, as determined in good
faith by the Board, of such portion of the assets and business of the
non-surviving person or persons as the Board of Directors determines in good
faith to be attributable to such Additional Shares,

                                      B-14

<Page>
Convertible Securities or Rights, and evidence of such determination shall be
filed with the minutes of the Corporation.

    (viii) If the Corporation effects any merger, consolidation or other
reorganization to which the Corporation is a party (other than (x) a merger or
consolidation in which the Company is the surviving or continuing corporation
and in which each share of Common Stock outstanding immediately prior to the
merger or consolidation remains unchanged in all material respects and (y) the
Transaction), any sale or conveyance to another person of all or substantially
all the assets of the Corporation or any statutory exchange of securities with
another person (including any exchange effected in connection with a merger of a
third person into the Corporation), then effective provision shall be made in
such transaction so that the holder of each share of Series B Preferred Stock
then outstanding shall have the right thereafter to convert such share into the
kind and amount of consideration receivable pursuant to such transaction by a
holder of the number of shares of Common Stock into which such share of Series B
Preferred Stock might have been converted immediately prior to such transaction,
assuming such holder of Common Stock failed to exercise its rights of election,
if any, as to the kind or amount of consideration receivable upon such
transaction (provided that if the kind or amount of consideration receivable
pursuant to such transaction is not the same for each share of Common Stock in
respect of which such rights of election shall not have been exercised
('NON-ELECTING SHARE'), then, for purposes of this Section 6(d)(viii), the kind
and amount of consideration receivable pursuant to such transaction for each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). Thereafter, the holders of
shares of Series B Preferred Stock shall be entitled to appropriate adjustments
with respect to their conversion rights to the end that the provisions set forth
in this Section 6 shall correspondingly be made applicable, as nearly as may
reasonably be, to any consideration thereafter deliverable on conversion of
shares of the Series B Preferred Stock. Notwithstanding the foregoing, this
Section 6(d)(viii) shall not apply with regard to the Series B Preferred Stock
to an event which is treated as a liquidation, dissolution or winding-up of the
Corporation with respect to such series pursuant to Section 4.

    (ix) If the Corporation distributes generally to holders of its outstanding
shares of Common Stock, evidences of its debt, securities or other assets
(excluding any cash dividends if the annualized per share amount thereof does
not exceed 9.0% of the Current Market Price or, if shares of Common Stock are
not traded on the NASDAQ and no Current Market Price can be determined on such
date pursuant to the methods specified in Section 6(e), the Valuation Price as
of the trading day immediately preceding the date of declaration of such
dividend and excluding any dividends or distributions payable in Rights or
Convertible Securities for which adjustment is otherwise made pursuant to this
Section 6(d)), the Conversion Price shall be adjusted by multiplying such
Conversion Price in effect immediately prior to the record date for the dividend
or distribution by a fraction of which (x) the numerator shall be the Current
Market Price or, if shares of Common Stock are not traded on the NASDAQ and no
Current Market Price can be determined on such date pursuant to the methods
specified in Section 6(e), the Valuation Price on such record date less the then
fair market value, as determined in good faith by the Board, of the portion of
the evidences of debt, securities or other assets so distributed or applicable
to the holder of one share of Common Stock and (y) the denominator shall be the
Current Market Price or, if shares of Common Stock are not traded on the NASDAQ
and no Current Market Price can be determined on such date pursuant to the
methods specified in Section 6(e), the Valuation Price on such record date. Such
adjustment shall become effective immediately after the record date for such
dividend or distribution.

    (x) No adjustment in the Conversion Price shall be required to be made
unless it would require an increase or decrease of at least one cent, but any
adjustments not made because of this Section 6(d)(x) shall be carried forward
and taken into account in any subsequent adjustment otherwise required. All
calculations under this Section 6(d) shall be made to the nearest cent or to the
nearest 1/100th of a share, as the case may be. All adjustments with respect to
a transaction or event shall apply to subsequent such transactions and events.
Anything in this Section 6(d) to the contrary notwithstanding, the Board of
Directors shall be entitled (but shall not be obligated) to make such
irrevocable reduction in the Conversion Price, in addition to the adjustments
required by this Section 6(d), as in its discretion it shall determine to be
advisable in order to avoid or diminish any income deemed to be received for
United States Federal income tax purposes by any holder of shares of Common
Stock or Series B

                                      B-15

<Page>
Preferred Stock resulting from any event or occurrence giving rise to an
adjustment pursuant to this Section 6(d) or from any similar event or
occurrence, and evidence of the Board of Director's determination of such
adjustment shall be filed with the minutes of the Corporation.

    (xi) Whenever the Conversion Price is adjusted pursuant to this Section
6(d),

    (A) the Corporation shall promptly file with the minutes of the Corporation
a certificate of the Corporation's chief accounting officer setting forth such
Conversion Price (and any change in the kind or amount of consideration to be
received by the holders of shares of the Series B Preferred Stock upon
conversion) after such adjustment and setting forth a brief statement of the
facts requiring such adjustment and the manner of computing the same, and

    (B) a notice stating that such Conversion Price has been adjusted, stating
the effective date of such adjustment and enclosing such certificate shall
forthwith be mailed by the Corporation to the holders of shares of the Series B
Preferred Stock at their addresses as shown on the stock books of the
corporation.

    (xii) If as a result of any adjustment pursuant to this Section 6(d), the
holder of any share of Series B Preferred Stock surrendered for conversion
becomes entitled to receive any consideration other than Common Stock,

    (A) the Conversion Price with respect to such other consideration 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 Common Stock
contained in this Section 6(d), and

    (B) in the case such consideration shall consist of shares of Common Stock
and some other kind of consideration or of two or more kinds of consideration,
the Board shall determine in good faith the fair allocation of the adjusted
Conversion Price between or among such types of consideration, and evidence of
such determination shall be filed with the minutes of the corporation.

    (e) Alternate Sources for Common Stock Share Prices. If for any reason the
Common Stock is no longer reported on NASDAQ or a national securities exchange
then the high and low price of a share of Common Stock on the relevant day for
purposes of calculating the Current Market Price shall be determined on the
basis of the last reported sale price, regular way, of the Common Stock as
reported on the composite tape, or similar reporting system, for issues listed
or admitted to trading on the principal national securities exchange on which
the Common Stock is then listed or admitted to trading or, if there is no such
reported sale on the day in question, on the basis of the average of the high
and low bid and asked quotations as so reported or, if the Common Stock is not
then listed or admitted to trading on any national securities exchange or on
NASDAQ, on the basis of the average of the high bid and low asked quotations on
the day in question in the over-the-counter market as reported by the National
Association of Securities Dealers Automated Quotation System, or, if not so
quoted, as reported by National Quotation Bureau, Incorporated, or a similar
organization.

    (f) Specified Events. For purposes of this Section 6(f), a 'SPECIFIED EVENT'
shall occur if (i) the Corporation authorizes the granting to the holders of the
Common Stock of any Rights or of any other rights, (ii) there is any capital
stock reorganization or reclassification of the Common Stock (other than (x) a
subdivision or combination of the outstanding Common Stock and other than a
change in the par value of the Common Stock and (y) the Transaction), or any
merger, consolidation or other reorganization to which the Corporation is a
party, or any statutory exchange of securities with another person and for which
approval of any stockholders of the Corporation is required, or any sale or
transfer of all or substantially all the assets of the Corporation or
(iii) there is a voluntary liquidation, dissolution or winding up of the
Corporation. If a Specified Event occurs, the Corporation shall cause to be
filed with the minutes of the Corporation, and shall cause to be mailed to the
holders of shares of the Series B Preferred Stock at their addresses as shown on
the stock books of the Corporation, at least 10 days prior to the applicable
date specified below, a notice stating,

    (A) the date on which a record is to be taken for the purpose of any
distribution or Rights relating to such Specified Event or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such distribution or Rights are to be determined, or

                                      B-16

<Page>
    (B) the date on which the reorganization, reclassification, consolidation,
merger, statutory exchange, sale, transfer, dissolution, liquidation or
winding-up relating to such Specified Event is expected to become effective, and
the date as of which it is expected that holders of Common Stock of record shall
be entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such Specified Event.

    (g) Reservation of Common Stock. The Corporation shall at all times reserve
and keep available, free from preemptive and subscription rights, out of its
authorized but unissued shares of Common Stock, for the purpose of effecting
conversions of the Series B Preferred Stock, the full number of shares of Common
Stock deliverable upon the conversion of all outstanding shares of Series B
Preferred Stock not theretofore converted. For this purpose, the number of
shares of Common Stock deliverable upon the conversion of all outstanding shares
of Series B Preferred Stock shall be computed as if at the time of computation
all such outstanding shares were held by a single holder.

    (h) Listing. With respect to any securities required to be delivered upon
conversion of the Series B Preferred Stock, the Corporation shall use all
commercially reasonable efforts to list or have approved for quotation such
securities prior to such delivery upon each securities exchange or automated
quotation system, if any, on which any securities of such class are already
listed or approved for quotation.

    (i) Taxes. The Corporation shall pay all documentary stamp or similar issue
or transfer taxes payable in respect of the issue or delivery of securities on
conversion of the Series B Preferred Stock; provided, however, that (i) the
Corporation shall not be required to pay any tax payable in respect of any
transfer involved in the issue or delivery of securities in a name other than
that of the holder of the shares of Series B Preferred Stock, to be converted
and (ii) no such issue or delivery shall be made unless and until such holder
has paid to the Corporation the amount of any such tax or has established, to
the satisfaction of the Corporation, that such tax has been paid or provided
for.

    (j) Termination of Conversion Rights. (i) (A) If shares of Common Stock are
traded on the NASDAQ or a Current Market Price can be determined pursuant to the
methods specified in Section 6(e) and if within any period of 30 consecutive
trading days for a period of at least 20 trading days (which 20 days must
include the last day of the 30 consecutive trading day period), the average of
the high and low sales prices of the Corporation's Common Stock on the principal
market on which such shares trade for such 20 trading days rounded up to the
nearest whole cent (the 'AVERAGE DAILY TRADING PRICE') exceeds 120% of the
Conversion Price then in effect or (B) if shares of Common Stock are not traded
on the NASDAQ and no Current Market Price can be determined on such date
pursuant to the methods specified in Section 6(e), the Valuation Price exceeds
105% of the Transaction Price, at its option and in its sole discretion upon
notice given as set forth below, the Corporation may terminate the conversion
rights set forth in this Section 6; provided, however, that the Corporation
shall not be permitted to exercise its right to terminate the conversion rights
of the Series B Preferred Stock for a period of 12 months following the
Transaction Effective Date. Beginning on the 10th day following receipt from the
Corporation of the notice setting forth its intention to terminate the
conversion rights and ending on the 45th day after receipt thereof, the
Corporation shall be required to redeem any shares of Series B Preferred Stock
at a redemption price equal to (i) if shares of Common Stock are traded on the
NASDAQ or a Current Market Price on such date can be determined pursuant to the
methods specified in Section 6(e), (x) if prior to the third anniversary of the
initial issuance of the Series B Preferred Stock, the Liquidation Amount plus
all accrued and unpaid dividends or (y) if on or after the third anniversary of
the initial issuance of the Series B Preferred Stock, the Redemption Price then
in effect as set forth in Section 5(b), or (ii) if shares of Common Stock are
not traded on the NASDAQ and no Current Market Price can be determined on such
date pursuant to the methods specified in Section 6(e), the Liquidation Amount
plus the product of (A) the difference between (x) the Valuation Price and
(y) the Conversion Price and (B) the number of shares of Common Stock that would
have been issuable upon conversion of the outstanding shares of Series B
Preferred Stock, of any holder that so requests, which request must be received
by the Corporation on or prior to the 45th day after such holder receives the
notice of the conversion termination. In order to exercise this right, such
holder must submit its request to the Corporation in the manner set forth in the
notice of conversion termination, the certificates for the shares to be so
redeemed and the number of shares to be

                                      B-17

<Page>
redeemed if less than the number represented by the certificate and the name in
which to issue any such shares not so redeemed, if different from the holder.
Following the 45th day after the holders receive the conversion termination
notice, the conversion rights for all outstanding shares of Series B Preferred
Stock shall terminate with no further action by the Corporation. For purposes of
this paragraph, a holder shall be deemed to have received notice, if such notice
is sent by facsimile to a facsimile number provided by such party for such
purpose, on the day it is so sent. If sent by first class mail, postage prepaid,
addressed to such holder at the last address for such holder that appears on the
books of the Corporation, notice shall be deemed to have been received on the
third business day after such notice has been mailed. If notice is also required
to be published as set forth in paragraph (ii) below, notice shall be deemed to
have been received on the day that it is so published.

    (ii) So long as the Series B Preferred Stock is not registered under the
Securities Act, notice of the termination of conversion rights shall be mailed
by first class mail, postage prepaid, addressed to the holders of record of the
Series B Preferred Stock at their respective last addresses as they appear on
the books of the Corporation and may be provided by facsimile to any number
provided by the holder for that purpose. If the Corporation registers the
outstanding shares of Series B Preferred Stock under the Securities Act, then
such notice shall be given by mail as described in the preceding sentence and
the Corporation shall also publish any such notice as set forth in Section 5(c)
hereof. The notice shall set forth:

    (A) the Average Daily Trading Price for the 20 trading days in question or
the applicable Valuation Price, as applicable, the dates for which such amounts
are presented, the Conversion Price then in effect for each such time period and
the percentage by which the Current Market Price, if applicable, exceeds such
Conversion Price;

    (B) the redemption price then in effect;

    (C) the place or places where certificates for the shares are to be
surrendered for redemption; and

    (D) that dividends on the shares to be redeemed will cease to accrue on the
date the holder delivers any shares to the Corporation for redemption (unless
the Corporation shall default in redeeming the shares on the redemption date).

    7. Status of Shares. Upon any redemption, repurchase, conversion, exchange
or other acquisition by the Corporation of shares of Series B Preferred Stock,
the shares of Series B Preferred Stock, so redeemed, repurchased, converted,
exchanged or acquired shall be retired and canceled and shall not be available
for reissuance.

    8. Voting Rights. (a) The holders of shares of the Series B Preferred Stock
shall not have the right to vote on or consent to any matter as shareholders of
the Corporation, except as required by applicable law or as otherwise provided
below. All matters on which the holders of the Series B Preferred Stock have the
right to vote may be approved at an annual or special meeting by holders of the
minimum number of shares of Series B Preferred Stock that would be required to
approve a matter if all shares were present and voting at a meeting called to
consider such matter or may be approved by one or more written consents signed
by all of the holders of shares of Series B Preferred Stock.

    (b) The consent of holders of at least a majority of the outstanding shares
of Series B Preferred Stock (voting separately as a class but excluding from any
calculation any shares of Series B Preferred Stock held by the Corporation or
any subsidiary thereof) shall be necessary to amend, alter or repeal any of the
provisions of this Article XII of the Articles of Incorporation of the
Corporation which would adversely affect the powers, preferences or rights of
the holders of shares of Series B Preferred Stock then outstanding.

    (c) If at any time the equivalent of six quarterly dividends payable on the
outstanding shares of Series B Preferred Stock are accrued and unpaid, whether
or not consecutive and whether or not declared, the holders of all outstanding
shares of Series B Preferred Stock, voting as a single class, together with the
holders entitled to vote of each series of Series A Preferred Stock and the
holders entitled to vote of all other series of Preferred Stock of the
Corporation that rank pari passu with or senior to the Series B Preferred Stock
and have similar voting rights, shall be entitled to elect at the next annual
meeting of shareholders of the Corporation 25% of the directors to the
Corporation's Board of Directors, but no less than two directors (or such
greater number as shall be provided in any

                                      B-18

<Page>
other series of Preferred Stock that shall at the time be entitled to vote with
the Series B Preferred Stock to elect directors). The proportion of the total
vote of all holders of Preferred Stock entitled to vote for such directors
attributable to the holders of the Series B Preferred Stock shall be based on
the percentage the aggregate Liquidation Amount for all outstanding shares of
Series B Preferred Stock bears to the aggregate liquidation amounts of all other
shares of Preferred Stock entitled to vote. Such directors shall serve until all
accumulated and unpaid dividends have been paid or declared and funds sufficient
for their payment have been set aside therefor.

    (d) For the avoidance of doubt, except as otherwise set forth in this
Section 8 or as required by law, the holders of the Series B Preferred Stock
shall not have the right to vote or consent with respect to (i) the increase or
decrease in the amount of authorized capital stock of any class or series, other
than increases or decreases in Series B Preferred Stock (to the extent specified
elsewhere herein), (ii) the authorization, creation (by way of reclassification
or otherwise) or issuance by the Board of Directors of any series of Preferred
Stock, other than any series that will rank senior to the Series B Preferred
Stock as to dividend distributions and distributions upon the liquidation,
winding up or dissolution of the Corporation or any obligation or security
convertible into or exercisable for or exchangeable into or evidencing a right
to purchase, shares of any series of Preferred Stock or the issuance by the
Board of Directors of any previously authorized class of capital stock of the
Corporation, or (iii) any merger, acquisition, disposition or share exchange
involving the Corporation where no shareholder vote is otherwise required or
pursuant to which the holders of the Series B Preferred Stock receive cash at
least equal to the Liquidation Amount.

    (e) The consent of the holders of at least a majority of the outstanding
shares of Series B Preferred Stock (voting separately as a class, but excluding
from any calculation any shares of Series B Preferred Stock held by the
Corporation or any subsidiary thereof) shall be necessary to increase the
authorized number of shares of Series B Preferred Stock and to authorize, create
or issue any series of Preferred Stock that will rank senior to the Series B
Preferred Stock as to dividend distributions, and distributions upon the
liquidation, winding up or dissolution of the Corporation.

    9. Valuation Procedures. (a) From time to time as a majority of the Board of
Directors of the Corporation shall determine, in good faith, which determination
shall be set forth in written resolutions, and in any event, not less than once
a year, the Corporation shall select in good faith and engage, at its own
expense, an independent, nationally recognized appraiser, investment bank,
accounting firm or consulting firm (the 'APPRAISER') to undertake a valuation of
the Corporation as of the date of the most recently ended fiscal quarter (a
'VALUATION'). The Corporation shall permit the Appraiser, upon reasonable
request, access to its properties and facilities to allow the Appraiser the
opportunity to make an inspection thereof. The Corporation shall make available
to the Appraiser all such financial information, documents and records of the
Corporation as the Appraiser may reasonably request for the purpose of
conducting a Valuation. The Corporation shall request that the Appraiser use its
reasonable efforts to complete a Valuation within 30 days following the date on
which it was engaged to undertake such Valuation. The Corporation shall also
instruct the Appraiser that it is to produce a report setting forth in
reasonable detail a Valuation and the methodology by which the Appraiser arrived
at such Valuation. The Corporation shall provide a copy of such report to each
holder of shares of Series B Preferred Stock.

    (b) The Corporation shall instruct the Appraiser to take into account the
following factors, among others, in arriving at a Valuation:

    (i) a Valuation shall be a valuation of the Corporation as an entirety and,
unless the Corporation shall have informed the Appraiser of plans to the
contrary, shall assume that the Corporation will continue to operate as a going
concern for the foreseeable future;

    (ii) the Appraiser shall consider the most recent budgets and projections
prepared by the Company's management;

    (iii) a Valuation shall not reflect any discount for minority interests or
disparate voting rights among classes of the Corporation's Capital Stock; and

    (iv) the Appraiser shall consider, to the extent it deems appropriate,
market valuations of comparable airlines.

                                      B-19

<Page>
    (c) The Appraiser shall derive a price per share of Common Stock from each
Valuation, which shall be based on the number of shares of Common Stock
outstanding on the date of such Valuation. Such price per share, as in effect
from time to time, is referred to herein as the 'VALUATION PRICE'.

    (d) Notwithstanding the foregoing, the Company shall be required to obtain a
Valuation as of the date its most recently ended fiscal quarter for purposes of
determining the Valuation Price applicable to Sections 6(d)(ii), 6(d)(ix) and
6(j) hereof.

June 18, 2001





The Special Committee of the Board of Directors
Amtran, Inc.
7337 West Washington Street
Indianapolis, Indiana 46231

The Special Committee:

    You have asked us to advise you with respect to the fairness, from a
financial point of view, to the shareholders of Amtran, Inc. (the 'Company')
other than J. George Mikelsons and his affiliates (J. George Mikelsons and such
affiliates are referred to herein as 'JGM' and such shareholders other than JGM
are collectively referred to herein as the 'Public Shareholders') of the
consideration to be received by such Public Shareholders pursuant to the terms
of the Agreement and Plan of Merger, dated as of June 18, 2001 (the 'Merger
Agreement'), by and between the Company and INDUS Acquisition Company ('Sub').
The Merger Agreement provides for, among other things, the merger of Sub with
and into the Company (the 'Merger') pursuant to which each outstanding share of
common stock, without par value (the 'Shares'), of the Company held by the
Public Shareholders (other than any such shares owned by the Company, Sub or any
other affiliate of JGM other than persons who are deemed to be affiliates of
Mikelsons by reason of their position as an officer or director of Amtran) will
be converted into the right to receive $23.00 per Share, net to the seller in
cash. The terms and conditions of the Merger are set forth in more detail in the
Merger Agreement.

    In connection with rendering our opinion, we have reviewed a draft of the
Merger Agreement, and for purposes hereof, we have assumed that the final form
of the Merger Agreement will not differ in any material respect from the draft
provided to us. We have also reviewed and analyzed certain publicly available
business and financial information relating to the Company for recent years and
interim periods to date, as well as certain internal financial and operating
information, including financial forecasts, analyses and projections prepared by
or on behalf of the Company and provided to us for purposes of our analysis, and
we have met with management of the Company to review and discuss such
information and, among other matters, the Company's business, operations,
assets, financial condition and future prospects.

    We have reviewed and considered certain financial and stock market data
relating to the Company, and we have compared that data with similar data for
certain other companies, the securities of which are publicly traded, that we
believe may be relevant or comparable in certain respects to the Company or one
or more of its businesses or assets, and we have reviewed and considered the
financial terms of certain recent acquisitions and business combination
transactions in the airline industry specifically, and in other industries
generally, that we believe to be reasonably comparable to the Merger or
otherwise relevant to our inquiry. We have also performed such other financial
studies, analyses, and investigations and reviewed such other information as we
considered appropriate for purposes of this opinion.

    In our review and analysis and in formulating our opinion, we have assumed
and relied upon the accuracy and completeness of all of the historical financial
and other information provided to or discussed with us or publicly available,
and we have not assumed any responsibility for independent verification of any
of such information. We have also assumed and relied upon the reasonableness and
accuracy of the financial projections, forecasts and analyses provided to us,
and

                                      C-1

<Page>
we have assumed that such projections, forecasts and analyses were reasonably
prepared in good faith and on bases reflecting the best currently available
judgments and estimates of the Company's management. We express no opinion with
respect to such projections, forecasts and analyses or the assumptions upon
which they are based. In addition, we have not reviewed any of the books and
records of the Company, or assumed any responsibility for conducting a physical
inspection of the properties or facilities of the Company, or for making or
obtaining an independent valuation or appraisal of the assets or liabilities of
the Company, and no such independent valuation or appraisal was provided to us.
We also have assumed that the transactions described in the Merger Agreement
will be consummated without waiver or modification of any of the material terms
or conditions contained therein by any party thereto. Our opinion is necessarily
based on economic and market conditions and other circumstances as they exist
and can be evaluated by us as of the date hereof.

    JGM owns a majority of the outstanding Shares, and you have advised us that
representatives of JGM have informed you, and we have assumed for purposes
hereof, that JGM is not prepared to consider offers for or to sell its Shares.
Accordingly, in the context of our engagement, we were not authorized to and did
not solicit third party indications of interest in acquiring all or any part of
the Company or its assets, or pursued any alternative transactions which may be
available to the Company. We express no opinion with respect to the values which
may have been obtained for the Company in a sale to a third party following an
auction process.

    We are acting as financial advisor to the Special Committee of the Board of
Directors of the Company (the 'Special Committee') in connection with the
proposed Merger and will receive a fee for rendering this opinion.

    In the ordinary course of our business, we may actively trade the debt and
equity securities of the Company for our own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities in accordance with our normal compliance procedures.

    Our opinion addresses only the fairness from a financial point of view to
the shareholders of the $23.00 per Share cash consideration to be received by
the Public Shareholders pursuant to the Merger, and we do not express any views
on any other terms of the Merger. Specifically, our opinion does not address the
Company's underlying business decision to effect the transactions contemplated
by the Merger Agreement. In addition, our opinion does not address the solvency
of the Company following consummation of the Merger, or at any time, nor do we
address issues regarding fraudulent conveyance or fraudulent transfer, and you
have advised us that the Company has arranged to receive an opinion with respect
to all of such matters from Houlihan, Lokey, Howard and Zukin.

    It is understood that this letter is for the benefit and use of the Special
Committee in its consideration of the Merger, and except for its inclusion in
its entirety, and its description, in any proxy statement required to be
circulated to shareholders of the Company relating to the Merger, may not be
used for any other purpose or reproduced, disseminated, quoted or referred to at
any time, in any manner or for any purpose without our prior written consent.
This opinion does not constitute a recommendation to any shareholder or as to
how such holder should vote with respect to the Merger, and should not be relied
upon by any shareholder as such.

    Based upon and subject to the foregoing, including the various assumptions
and limitations set forth herein, it is our opinion that as of the date hereof,
the $23.00 per Share cash consideration to be received by the Public
Shareholders pursuant to the Merger is fair to such Public Shareholders from a
financial point of view.


                                          Very truly yours,
                                          /s/ Dresdner Kleinwort Wasserstein,
                                          Inc.
