                                WARRANT AGREEMENT

     This WARRANT AGREEMENT (this "Agreement"), dated as of September 15, 2003,
is made and entered into by and between CHART INDUSTRIES, INC., a Delaware
corporation (the "Company"), and NATIONAL CITY BANK, a national banking
association (in its capacity as warrant agent hereunder, the "Warrant Agent").

                                 R E C I T A L S

     A. The Company proposes to effect a Amended Joint Prepackaged
Reorganization Plan, dated September 3, 2003 (as further modified, supplemented
or amended, the "Plan") pursuant to chapter 11 of title 11 of the United States
Code, 11 U.S.C. (S)(S) 101 et seq., whereby, among other things, the Company
proposes to issue 280,281 warrants (the "Warrants") entitling the holders of Old
Chart Common Stock Interests (as defined in the Plan) to purchase initially an
aggregate of up to 280,281 shares (as adjusted from time to time pursuant to
this Agreement, the "Shares") of the Company's Common Stock, par value $0.01 per
share ("Common Stock"), after the consummation of the Plan, such Warrants to be
authorized and issued as of the Consummation Date (as defined in the Plan).

     B. The Warrant Agent, at the request of the Company, has agreed to act as
the agent of the Company in connection with the issuance, registration,
transfer, exchange, exercise and conversion of the Warrants.

     NOW, THEREFORE, in consideration of the premises and mutual agreements
herein set forth, the parties hereto agree as follows:

     SECTION 1. Appointment of Warrant Agent. The Company hereby appoints the
Warrant Agent to act as agent for the Company in accordance with the
instructions hereinafter set forth in this Agreement; and the Warrant Agent
hereby accepts such appointment, upon the terms and conditions hereinafter set
forth.

     SECTION 2. Issuances. Subject to the provisions of this Agreement, in
accordance with the terms of the Plan, on (and from time to time after) the
Consummation Date, Warrants to purchase the Shares will be issued by the Company
in the amounts and to the recipients specified in the Plan or as otherwise set
forth herein. On, or as soon as reasonably practicable after, the Distribution
Date (as defined in the Plan), the Company will deliver, or cause to be
delivered, one or more Warrant Certificates (as defined below) evidencing the
Warrants in accordance with the terms of the Plan or as otherwise set forth
herein.

     SECTION 3. Form of Warrant Certificates. Subject to Section 6, the Warrants
to be issued under the Plan to holders of Old Chart Common Stock Interests shall
initially be issued in the form of one or more warrant certificates (the
"Warrant Certificates") in substantially the form set forth in Exhibit A, the
forms of election to exercise and of assignment to be printed on the reverse
thereof in substantially the forms set forth in Exhibit B and Exhibit C hereto,
together with such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Agreement, and may have such
letters, numbers or other marks of identification

                                       1

<PAGE>

and such legends or endorsements placed thereon as may be required to comply
with any law or with any rules made pursuant thereto or with any rules of any
securities exchange or as may, consistently herewith, be determined by the
officers executing such Warrant Certificates, as evidenced by their execution of
the Warrant Certificates.

     Each Warrant Certificate shall represent such number of the outstanding
Warrants as specified therein, and each shall provide that it shall represent
the aggregate amount of outstanding Warrants from time to time endorsed thereon
and that the aggregate number of Shares purchasable upon the exercise of each
Warrant may from time to time be reduced or increased, as appropriate, in
accordance with the terms of this Agreement.

     SECTION 4. Execution of Warrant Certificates. Warrant Certificates shall be
signed on behalf of the Company by its Chairman of the Board of Directors, its
Chief Executive Officer, its Chief Financial Officer or its President (each, an
"Officer"). Each such signature upon the Warrant Certificates may be in the form
of a facsimile signature of any such Officer and may be imprinted or otherwise
reproduced on the Warrant Certificates and for that purpose the Company may
adopt and use the facsimile signature of any Officer.

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

     SECTION 5. Registration and Countersignature. The Warrant Agent shall, upon
receipt of the Warrant Certificates duly executed on behalf of the Company,
countersign one or more Warrant Certificates evidencing the Warrants and shall
deliver such Warrant Certificates to or upon the written order of the Company. A
Warrant Certificate shall be, and shall remain, subject to the provisions of
this Agreement until such time as all of the Warrants evidenced thereby shall
have been duly exercised or shall have expired or been canceled in accordance
with the terms hereof.

     No Warrant Certificate shall be valid for any purpose, and no Warrant
evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the signature of the Warrant Agent. Such signature by the
Warrant Agent upon any Warrant Certificate executed by the Company shall be
conclusive evidence that such Warrant Certificate so countersigned has been duly
issued hereunder.

     The Warrant Agent shall keep, at an office designated for such purpose,
books (the "Warrant Register") in which, subject to such reasonable regulations
as it may prescribe, it shall register the Warrant Certificates and exchanges
and transfers of outstanding Warrant Certificates in accordance with the
procedures set forth in Section 6, all in form satisfactory to the Company and
the Warrant Agent. No service charge shall be made for any exchange or
registration of

                                       2

<PAGE>

transfer of the Warrant Certificates, but the Company may require payment of a
sum sufficient to cover any stamp or other tax or other governmental charge that
may be imposed in connection with any such exchange or registration of transfer.
The Warrant Agent shall have no obligation to effect an exchange or register a
transfer unless and until any payments required by the immediately preceding
sentence have been made.

     Prior to due presentment for registration of transfer or exchange of any
Warrant in accordance with the procedures set forth in this Agreement, the
Warrant Agent and the Company may deem and treat the person in whose name any
Warrant is registered (the "Holder" of such Warrant) as the absolute owner of
such Warrant (notwithstanding any notation of ownership or other writing made in
a Warrant Certificate by anyone), for the purpose of any exercise thereof, any
distribution to the Holder thereof and for all other purposes, and neither the
Warrant Agent nor the Company shall be affected by notice to the contrary.

     SECTION 6. Registration of Transfers and Exchanges.

     (a) When Warrant Certificates are presented to the Warrant Agent with a
request:

          (i) to register the transfer of the Warrant Certificates; or

          (ii) to exchange such Warrant Certificates for an equal number of
Warrant Certificates of other authorized denominations,

the Warrant Agent shall register the transfer or make the exchange as requested
if its requirements for such transactions are met; provided, however, that the
Warrant Certificates presented or surrendered for registration of transfer or
exchange shall be duly endorsed or accompanied by a written instruction of
transfer in form satisfactory to the Warrant Agent, duly executed by the Holder
thereof or by his attorney, duly authorized in writing.

     (b) No Warrants, or Shares issuable upon exercise of the Warrants, shall be
sold, exchanged or otherwise transferred in violation of the Securities Act of
1933, as amended (the "Securities Act"), or state securities laws. The Company
or the Warrant Agent may require that, to the extent reasonable as a condition
to any sale, exchange or transfer of a Warrant or such Shares that the Holder
deliver to the Company and the Warrant Agent an opinion of counsel, which
opinion and counsel shall be reasonably satisfactory to the Company, to the
effect that such sale, exchange or transfer is made in compliance with the
Securities Act and all applicable state securities laws or pursuant to an exempt
transaction under the Securities Act and state securities laws. The provisions
of this paragraph (b) shall not apply to the exercise of any Warrant to the
extent that the Shares issued upon such exercise (and any unexercised portion of
the Warrant so exercised) shall be issued to the same Holder that exercised such
Warrant.

     (c) The Warrant Certificates and the Shares issuable upon exercise of the
Warrants shall bear such legends as the Company reasonably shall determine
reflecting the restrictions in the immediately preceding Section 6(b).

                                       3

<PAGE>

     (d) The Company and the Warrant Agent shall be obligated with respect to
transfers and exchanges of Warrants as follows:

          (i) To permit registrations of transfers and exchanges, the Company
shall execute and the Warrant Agent is hereby authorized to countersign, in
accordance with the provisions of Section 3 and this Section 6, Warrant
Certificates as required pursuant to the provisions of this Section 6 and for
the purpose of any distribution of Warrant Certificates contemplated by Section
14.

          (ii) All Warrant Certificates issued upon any registration of transfer
or exchange of Warrant Certificates shall be the valid obligations of the
Company, entitled to the same benefits under this Agreement as the Warrant
Certificates surrendered upon such registration of transfer or exchange.

          (iii) No service charge shall be made to a Holder for any
registration, transfer or exchange.

          (iv) Subject to Section 6(a) and this Section 6(d), the Warrant Agent
shall, upon receipt of all information required to be delivered hereunder, from
time to time register the transfer of any outstanding Warrants represented by
Warrant Certificates in the Warrant Register, upon surrender of Warrant
Certificates representing such Warrants at the Warrant Agent Office (as defined
below), duly endorsed, and accompanied by a completed form of assignment, duly
signed by the Holder thereof or by the duly appointed legal representative
thereof or by a duly authorized attorney, such signature to be guaranteed by (x)
a bank or trust company, (y) a broker or dealer that is a member of the National
Association of Securities Dealers, Inc. or (z) a member of a national securities
exchange. Upon any such registration of transfer, a new Warrant Certificate
shall be issued to the transferee.

     SECTION 7. Duration and Exercise of Warrants.

     (a) The Warrants shall expire upon the earlier to occur of (i) 5:00 p.m.,
Eastern Time on September 15, 2010 or (ii) the time of consummation of a
transaction constituting a Termination Event (as described in Section 14(c))
(the "Expiration Time"). At the Expiration Time, the Warrants will become void
and of no value.

     (b) Subject to the provisions of this Agreement, including Section 14, each
Warrant shall entitle the Holder thereof to purchase from the Company (and the
Company shall issue and sell to such Holder) one fully paid and nonassessable
Share at a price equal to $32.97 per share (as the same may be hereafter
adjusted pursuant to Section 14, the "Exercise Price").

     (c) From and after the Consummation Date and until the Expiration Time, the
Holder of a Warrant may exercise such Holder's right to purchase Shares by:

                                       4

<PAGE>

          (i) providing written notice of such election ("Warrant Exercise
Notice") to exercise the Warrant to the Warrant Agent at the address set forth
in Section 20(b) hereof, "Re: Chart Industries, Inc. Warrant Exercise", by
certified mail, return receipt requested, by nationally recognized overnight
courier service, by hand or by facsimile, no later than the Expiration Time,
which Warrant Exercise Notice shall be in the form of an election to purchase
Shares of the Company substantially in the form set forth in Exhibit B hereto,
properly completed and executed by the Holder;

          (ii) delivering no later than 5:00 p.m., Eastern Time, on the business
day immediately prior to the Settlement Date (as defined below) the Warrant
Certificates evidencing such Warrants to the Warrant Agent; and

          (iii) paying the applicable Exercise Price multiplied by the number of
Shares in respect of which such Warrants are being exercised (the "Exercise
Amount"), together with any applicable taxes and governmental charges. The date
three business days after a Warrant Exercise Notice is delivered is referred to
for all purposes under this Agreement as the "Settlement Date."

     (d) The Exercise Amount shall be payable (i) in lawful money of the United
States of America by wire transfer in immediately available funds of the
Exercise Amount to an account of the Warrant Agent specified in writing by the
Warrant Agent for such purpose, (ii) by delivery of an official bank check or
cashier's check in immediately available funds of the Exercise Amount to the
Warrant Agent at its corporate office, (iii) by Cashless Exercise (as defined
below), or (iv) by any combination of the foregoing, in each case no later than
5:00 p.m., Eastern Time, on the business day immediately prior to the Settlement
Date.

     (e) Any exercise of a Warrant pursuant to the terms of this Agreement shall
be irrevocable and shall constitute a binding agreement between the Holder and
the Company, enforceable in accordance with its terms.

     A "Cashless Exercise" shall mean an exercise of a Warrant or Warrants
without payment of the Exercise Price in cash by surrendering such Warrant or
Warrants (represented by one or more Warrant Certificates) and, in exchange
therefor, receiving such number of Shares equal to the product of (1) that
number of Shares for which such Warrant or Warrants are exercisable and which
would be issuable in the event of an exercise with full payment in cash of the
Exercise Price and (2) the Cashless Exercise Ratio (as defined below). The
"Cashless Exercise Ratio" shall equal a fraction, the numerator of which is the
excess of the Market Price (as defined in Section 14(b) below) per share of
Common Stock on the date of exercise over the Exercise Price per share of Common
Stock as of the date of exercise and the denominator of which is the Market
Price per share of Common Stock on the date of exercise. A Holder may exercise
all or any number of whole Warrants represented by a Warrant Certificate. Upon
surrender of a Warrant Certificate representing more than one Warrant in
connection with a Holder's option to elect a Cashless Exercise, such Holder must
specify the number of Warrants for which such Warrant Certificate is to be
exercised (without giving effect to such Cashless Exercise). All provisions of
this Agreement shall be applicable with respect to a Cashless Exercise of a
Warrant Certificate for less than the full number of Warrants represented
thereby.

                                       5

     (f) The Warrant Agent shall:

          (i) examine all Warrant Exercise Notices and all other documents
delivered to it by or on behalf of Holders as contemplated by the Warrant
Certificates to ascertain whether, on their face, such Warrant Exercise Notices
and any such other documents have been executed and completed in accordance with
their terms and the terms of the Warrant Certificates. In each case where a
Warrant Exercise Notice or other document appears on its face to have been
improperly completed or executed or some other irregularity in connection with
the exercise of the Warrants exists, the Warrant Agent shall endeavor to inform
the appropriate parties (including the person submitting such instrument) of the
need for fulfillment of all requirements, specifying those requirements which
appear to be unfulfilled;

          (ii) inform the Company of and cooperate with and assist the Company
in resolving any reconciliation problems between Warrant Exercise Notices
received and delivery of Warrants to the Warrant Agent's account;

          (iii) advise the Company no later than three business days after
receipt of a Warrant Exercise Notice, of (A) the receipt of such Warrant
Exercise Notice and the number of Warrants exercised in accordance with the
terms and conditions of this Agreement, (B) the instructions with respect to
delivery of the Shares deliverable upon such exercise, and (C) such other
information as the Company shall reasonably require;

          (iv) notify, by such time as necessary to ensure a prompt closing, the
Transfer Agent (as defined below) of the Common Stock with a copy to the
Company, of such name or names as directed by the Holder in which to issue the
Shares on the Settlement Date; and

          (v) subject to Common Stock being made available to the Warrant Agent
by or on behalf of the Company for delivery to the Transfer Agent, liaise with,
and endeavor to effect such delivery to, the Transfer Agent in accordance with
its requirements.

     (g) As soon as practicable after the exercise of any Warrant, the Company
shall issue, or otherwise deliver (or cause the Transfer Agent to deliver), in
authorized denominations to or upon the order of the Holder of the Warrant
Certificates evidencing such Warrant, by delivery to the address designated by
such Holder in its Warrant Exercise Notice, a physical certificate representing
the number of Shares to which such Holder is entitled, in fully registered form,
registered in such name or names as may be directed by such Holder. If less than
all of the Warrants evidenced by a Warrant Certificate surrendered upon the
exercise of Warrants are exercised at any time prior to the date of expiration
for the Warrants, a new Warrant Certificate or Certificates shall be issued to
or upon the order of the Holder for the remaining number of Warrants evidenced
by the Warrant Certificate so surrendered, and the Warrant Agent is hereby
authorized to countersign the required new Warrant Certificate or Certificates
pursuant to the provisions of Section 6 and this Section 7.

     (h) If any filing or notification becomes necessary pursuant to the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), based upon the planned exercise of one or more Warrants, the Holder
thereof shall notify the Company of such

                                       6

<PAGE>

requirement and the Holder and the Company shall, prior to exercise, make any
necessary filings and notifications required to comply with the HSR Act at the
Holder's sole expense, including supplying any required additional information
or documents necessary for such notifications or filings. The Holder and the
Company agree to cooperate with each other in connection with such filings and
notifications, and to keep each other informed of the status of the proceedings
and communications with any federal, state, local, municipal, foreign or other
governmental agency, authority or body relating thereto. The Holder shall be
required to pay all required filing fees under the HSR Act. The Holder agrees
that prior to any exercise of a Warrant, if reasonably required by the Company,
it shall certify to the Company the Holder's compliance with the foregoing and
that any applicable waiting period under the HSR Act has expired. Each Holder by
acceptance of a Warrant agrees to comply with the provisions of this Section
7(h).

     SECTION 8. Rights Upon Dissolution or Liquidation. Notwithstanding any
other provision of this Agreement, in the event that, at any time after the date
hereof and prior to the Expiration Time, there shall be a voluntary or
involuntary dissolution, liquidation or winding up of the Company, then the
Company shall (or shall cause the Warrant Agent to) give notice by first-class
mail to each Holder of an outstanding Warrant at such Holder's address as it
appears on the Warrant Register maintained by the Warrant Agent, not less than
twenty days before any date set for definitive action, of the date on which such
dissolution, liquidation or winding up shall take place, as the case may be.
Such notice shall also specify the date as of which the holders of the shares of
record of Common Stock or other securities, if any, underlying the Warrants
shall be entitled to exchange their shares for securities, money or other
property deliverable upon such dissolution, liquidation or winding up, as the
case may be.

     SECTION 9. Cancellation of Warrants. If the Company shall purchase or
otherwise acquire Warrants, the Warrant Certificates representing such Warrants
shall thereupon be delivered to the Warrant Agent and be canceled by it and
retired. The Warrant Agent shall cancel all Warrant Certificates surrendered for
exchange, substitution, transfer or exercise in whole or in part. Such canceled
Warrant Certificates shall thereafter be disposed of in a manner satisfactory to
the Company.

     SECTION 10. Mutilated or Missing Warrant Certificates. If any of the
Warrant Certificates shall be mutilated, lost, stolen or destroyed, the Company
shall issue, and the Warrant Agent shall countersign and deliver, in exchange
and substitution for and upon cancellation of the mutilated Warrant Certificate,
or in lieu of and substitution for the Warrant Certificate lost, stolen or
destroyed, a new Warrant Certificate of like tenor and representing an
equivalent number of Warrants, but only upon receipt of evidence reasonably
satisfactory to the Company and the Warrant Agent of the loss, theft or
destruction of such Warrant Certificate and the delivery of an affidavit of loss
and bond of indemnity, and payment (if customarily required) of a reasonable
bonding fee, in each case if requested by either the Company or the Warrant
Agent, also reasonably satisfactory to them. Upon the issuance of any new
Warrant Certificate under this Section 10, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other reasonable out-of-pocket expenses
(including the fees and expenses of the Warrant Agent) in connection therewith.

                                       7

<PAGE>

     SECTION 11. Reservation of Shares. For the purpose of enabling it to
satisfy any obligation to issue Shares upon exercise of Warrants, the Company
will at all times through the Expiration Time, reserve and keep available, free
from preemptive rights and out of its aggregate authorized but unissued or
treasury shares of Common Stock, the number of Shares deliverable upon the
exercise of all outstanding Warrants, and the transfer agent for the Company's
Common Stock (such agent, in such capacity, as may from time to time be
appointed by the Company, the "Transfer Agent") is hereby irrevocably authorized
and directed at all times to reserve such number of authorized and unissued or
treasury shares of Common Stock as shall be required for such purpose. The
Company will keep a copy of this Agreement on file with such Transfer Agent and
with every transfer agent for any shares of the Company's capital stock issuable
upon the exercise of Warrants pursuant to Section 7. The Warrant Agent is hereby
irrevocably authorized to requisition from time to time from such Transfer Agent
stock certificates issuable upon exercise of outstanding Warrants, and the
Company will supply such Transfer Agent with duly executed stock certificates
for such purpose.

     Before taking any action that would cause an adjustment pursuant to Section
14 reducing any Exercise Price below the then par value (if any) of the Shares
issuable upon exercise of the Warrants, the Company will take any corporate
action that may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue fully paid and nonassessable Shares at
such Exercise Price as so adjusted.

     The Company covenants that all Shares issued upon exercise of the Warrants
will, upon delivery of the Company assuming payment in full of the Exercise
Price therefor, be fully paid and nonassessable and free from all taxes, liens,
charges and security interests of any nature whatsoever other than such liens,
charges and security interests granted by the Holder.

     SECTION 12. Stock Exchange Listings. So long as any Warrants remain
outstanding, if the Shares are (i) listed on a national securities exchange or
(ii) listed for quotation on the Nasdaq National Market System or any other
over-the-counter quotation system, the Company will use commercially reasonable
efforts to have each of the Shares reserved for issuance hereunder listed on
such exchange or system.

     SECTION 13. Provision of Financial Information.

     (a) So long as any Warrants remain outstanding and the Company is required
to file annual reports, quarterly reports and other documents with the
Securities and Exchange Commission (the "SEC") pursuant to Section 13(a) or
15(d) of the Securities Exchange Act of 1934, as amended (the "Reports"), the
Company (i) will file the Reports with the SEC when due and (ii) if listed on a
national securities exchange or listed for quotation on a national market system
or other over-the-counter quotation system, will make the Reports generally and
readily available as required by the appropriate listing standards.

     (b) So long as any Warrants remain outstanding and in the event the Company
is not required to file Reports with the SEC, the Company shall mail to the
Warrant Agent five copies of its (x) quarterly reports (containing unaudited
financial reports prepared in accordance with generally accepted accounting
principles) within sixty days, or at such earlier time as such

                                       8

<PAGE>

reports are provided under the Investor Rights Agreement of Chart Industries,
Inc., dated September 15, 2003 (hereinafter the "Investor Rights Agreement"),
after the close of each of the first three quarters of each fiscal year, and (y)
annual reports (containing audited financial reports prepared in accordance with
generally accepted accounting principles) within one hundred twenty days, or at
such earlier time as such reports are provided under the Investor Rights
Agreement, after the close of each fiscal year. The Warrant Agent shall deliver
a copy of any of the financial reports it receives under this Section 13(b) to
any Holder promptly upon the written request of such Holder given to the Warrant
Agent.

     SECTION 14. Adjustment of Exercise Price and Number of Shares Purchasable
or Number of Warrants. The Exercise Price, the number of shares of Common Stock
purchasable upon the exercise of each Warrant and the number of Warrants
outstanding are subject to adjustment from time to time upon the occurrence of
the events enumerated in this Section 14.

     (a) Changes in Capital Stock. If the Company at any time or from time to
time after the date hereof shall (i) pay a dividend or make a distribution of
Common Stock, in each case, consisting of shares of Common Stock, (ii) subdivide
its outstanding shares of Common Stock into a larger number of shares of Common
Stock (including by means of a stock split), (iii) combine its outstanding
shares of Common Stock into a smaller number of shares of Common Stock or (iv)
issue, in a reclassification of the Common Stock, other securities of the
Company (including any such reclassification in connection with a consolidation
or merger of the Company in which the Company is the surviving entity), the
number of Shares purchasable upon exercise of each Warrant immediately prior
thereto shall be adjusted so that the Holder of each Warrant shall be entitled
upon exercise to receive the kind and number of Shares or other securities of
the Company which such Holder would have owned or have been entitled to receive
after the happening of any of the events described above, had such Warrant been
exercised immediately prior to the happening of such event or any record date
with respect thereto. An adjustment made pursuant to this paragraph (a) shall
become effective on the effective date of such event retroactive to the record
date, if any, for such event.

     (b) Distributions. If the Company at any time or from time to time after
the date hereof shall distribute to all holders of Common Stock (including any
such distribution made to the shareholders of the Company in connection with a
consolidation or merger in which the Company is the continuing corporation)
evidences of its indebtedness, shares of another class of its capital stock,
cash or other property of any nature (other than distributions and dividends
payable in shares of Common Stock), or any options, warrants or other rights to
subscribe for or purchase any of the foregoing, then, in each case, the Exercise
Price shall be adjusted by multiplying the Exercise Price in effect immediately
prior to the record date for the determination of shareholders entitled to
receive such distribution by a fraction, the numerator of which shall be the
Market Price (as defined below) per share of Common Stock as of the business day
immediately preceding such record date, less the fair market value (as
determined in good faith by the Board of Directors of the Company (including any
authorized committee thereof, the "Board of Directors"), whose determination
shall be conclusive for all purposes and described in a reasonably detailed
statement filed with the Warrant Agent) of the portion of the evidences of
indebtedness, shares or property so to be distributed (net of the exercise price
or purchase price therefor in the case of distribution of options, warrants or
other rights to subscribe

or purchase such indebtedness, shares or other property), applicable to one
share, and the denominator of which shall be such Market Price per share of
Common Stock as of the business day immediately preceding such record date. Such
adjustment shall be made whenever any such distribution is made and shall become
effective at the close of business on such record date.

     The term "Market Price" shall mean (x) the average closing price of a share
of Common Stock for the ten consecutive trading days immediately preceding, but
not including, the date of determination (which shall be the date of exercise of
this Warrant in the case such determination results from exercise) as reported
on the principal national securities exchange on which the shares of Common
Stock are listed or admitted to trading or (y) if not listed or admitted to
trading on any national securities exchange, the average of the closing bid and
asked prices during such ten trading day period in the over-the-counter market
as reported by the Nasdaq National Market System or any other over-the-counter
quotation system or (z) in all other cases, as determined in good faith by the
Board of Directors, whose determination shall be conclusive absent manifest
error.

     (c) Reorganization, Reclassification, Consolidation, Merger or Sale;
Termination Event.

          (i) Subject to Section 14(c)(ii), if any capital reorganization of the
Company, or any reclassification of the Common Stock, or any consolidation or
merger of the Company with or into any other person, or any sale, lease or other
transfer of all or substantially all of the assets of the Company to any other
person, shall be effected in such a way that the holders of the Common Stock
shall be entitled to receive (either directly or upon subsequent liquidation)
stock, securities, cash or other property (whether such stock, securities, cash
or other property are issued or distributed by the Company or any other person)
with respect to or in exchange for the Common Stock (each such transaction, an
"Organic Change"), then, as a condition to consummation of such Organic Change,
lawful, enforceable and adequate provision shall be made whereby the Holders of
the Warrants shall thereafter have the right to acquire and receive upon
exercise of such Warrants, in lieu of or in addition to (as the case may be) the
shares of Common Stock immediately theretofore acquirable and receivable upon
exercise of such Warrants, such shares of stock, securities, cash or other
property issuable or payable in the Organic Change with respect to or in
exchange for such number of outstanding shares of Common Stock as would have
been received upon exercise of such Warrants had such Warrants been exercised
immediately before such Organic Change, subject to adjustments for events
subsequent to the effective date of such Organic Change as nearly equivalent as
may be practicable to the adjustments provided for in this Section 14. The
Company shall not effect any Organic Change unless prior to the consummation
thereof, the successor entity (if different from the Company) resulting from
such consolidation or merger or the entity purchasing, leasing or otherwise
acquiring all or substantially all of its assets assumes by written instrument
delivered to the Warrant Agent the obligation to deliver to each such Holder
such shares of stock, securities, cash or other property as, in accordance with
the foregoing provisions, such Holder may be entitled to acquire upon exercise
of the Warrants. In any such event, effective provisions shall be made in the
certificate or articles of incorporation of the resulting or surviving person,
or in any contract of sale, merger, conveyance, lease, transfer or otherwise, so
that the provisions set forth in this Agreement for the protection of the rights
of the Holders of the Warrants shall

                                       10

<PAGE>

thereafter continue to be applicable. The foregoing provisions of this Section
14(c) shall similarly apply to successive reorganizations, reclassifications,
consolidations, mergers, sales, leases or other transfers, provided, that no
adjustment under this Section 14(c) shall duplicate an adjustment under Section
14(a) or 14(b). Notwithstanding the foregoing, the adjustments required by this
Section 14(c)(i) shall not apply to any transaction constituting a Termination
Event (as defined below).

          (ii) In the event that the Company or its successor entity, as
applicable, after the date hereof shall propose to effect (A) a Sale of the
Company or (B) a New Initial Public Offering (the consummation of any such
transaction is referred to herein as a "Termination Event", provided that no
such transaction shall be deemed to be consummated for purposes of this Section
14(c) before the expiration of the notice period relating to the Termination
Event required under Section 16), then the Company shall cause written notice of
such Termination Event to be filed with the Warrant Agent and to be given to the
Holders of the Warrants in the manner and at the time specified in Section 16.
The Holders of Warrants shall continue to be entitled to exercise Warrants until
such Termination Event (including for such period, if any, as may be required
under the final sentence of Section 16), but each Warrant and all rights of any
Holder thereof shall automatically be canceled and terminated at the Expiration
Time (or such later time, if any, as may be determined in accordance with the
final sentence of Section 16) to the extent not exercised prior to such time,
and no Warrant may be exercised thereafter. Notwithstanding the foregoing, no
such transaction shall constitute a Termination Event, and this Section
14(c)(ii) shall not apply to such transaction, if (x) such transaction is
effected pursuant to the terms of the Plan, or (y) one or more Controlling
Stockholders (and/or their affiliates) beneficially own (such beneficial
ownership to be determined in accordance with Section 13(d) of the Exchange Act
and the rules of the SEC promulgated thereunder) more than 20% of the combined
Voting Power of the then-outstanding securities of the person surviving such
transaction, or the person purchasing, leasing or otherwise acquiring assets of
the Company, immediately after consummation of such transaction, or (z) one or
more Controlling Stockholders (and/or their affiliates) have the right under any
contractual agreement to cause to be elected a majority of the Directors of the
person surviving such transaction, or the person purchasing, leasing or
otherwise acquiring assets of the Company, immediately after consummation of
such transaction.

          (iii) As used in this Agreement, the following capitalized terms shall
have the following meanings:

     "Controlling Stockholders" means OCM Principal Opportunities Fund II, L.P.,
a Delaware limited partnership, and Audax Chart LLC, a Delaware limited
liability company, and their successors as Required Controlling Holder(s)
entitled to designate a majority of Directors pursuant to Section 7A(ii)(b)
and/or (e) of the Investor Rights Agreement.

     "Director" means a member of the Board of Directors of the Company or any
successor entity (including a successor by purchase, lease or other acquisition
of all or substantially all of the assets of the Company).

                                       11

<PAGE>

     "Exchange Act" means the Securities Exchange Act of 1934, as amended, and
the rules and regulations thereunder, as such law, rules and regulations may be
amended from time to time.

     "New Initial Public Offering" means the initial public offering of shares
of Common Stock pursuant to a Registration Statement filed at any time after the
Company has ceased to be required to file reports with the SEC pursuant to
Section 13 or Section 15(d) of the Exchange Act.

     "Registration Statement" means a registration statement filed by the
Company with the SEC for a public offering and sale of Common Stock by the
Company (other than a registration statement on Form S-8 or Form S-4, or their
successors, or any other form for a similar limited purpose, or any registration
statement covering only securities proposed to be issued in exchange for
securities or assets of another corporation).

     "Sale of the Company" means any consolidation or merger of the Company with
or into any other person (other than a Controlling Stockholder or any affiliate
thereof), or any sale, lease or other transfer of all or substantially all of
the assets of the Company to any other person (other than a Controlling
Stockholder or any affiliate thereof), which, in either case, results upon
consummation thereof in: (i) any person or group, other than a Controlling
Stockholder (and/or any affiliate thereof), becoming the beneficial owner (such
beneficial ownership to be determined in accordance with Section 13(d) of the
Exchange Act and the rules of the SEC promulgated thereunder) of more than 50%
of the combined Voting Power of the then-outstanding securities of (A) the
person surviving such transaction (in the case of a consolidation or merger) or
(B) the person purchasing, leasing or otherwise acquiring assets of the Company
(in the case of a sale, lease or other transfer of all or substantially all of
the assets of the Company); or (ii) the stockholders of the Company immediately
prior to such transaction failing to receive in such transaction in exchange
for, or upon conversion of, or otherwise in respect of their shares of Company
stock, equity securities (including shares of Company stock retained by such
stockholders) representing legal or beneficial ownership (such beneficial
ownership to be determined in accordance with Section 13(d) of the Exchange Act
and the rules of the SEC promulgated thereunder) immediately after such
transaction of at least 50% of the combined Voting Power of the then-outstanding
securities of (A) the person surviving such transaction (in the case of a
consolidation or merger) or (B) the person purchasing, leasing or otherwise
acquiring assets of the Company (in the case of a sale, lease or other transfer
of all or substantially all of the assets of the Company). Notwithstanding the
foregoing, a "Sale of the Company" shall not be deemed to have occurred for
purposes of this Agreement solely because of a merger, consolidation or sale,
lease or other transfer of all or substantially all of the assets of any Company
subsidiary, unless the assets of such subsidiary represent substantially all of
the assets of the Company.

     "Voting Power" means, at any time, the total votes relating to the
then-outstanding securities entitled to vote generally in the election of
Directors.

     (d) Other Dilutive Events. The Board of Directors shall make such
additional adjustments in application of such provisions as it deems necessary
or appropriate in its sole

                                       12

<PAGE>

discretion, to effectuate the essential intent and principles established in
paragraphs (a) through (c) above, necessary to preserve the purchase rights
represented by each Warrant.

     (e) No De Minimis Adjustment. No adjustment in the number of Shares
purchasable upon exercise of a Warrant shall be required unless such adjustment
would require an increase or decrease of at least one percent (1.0%) in the
number of Shares purchasable upon the exercise of each Warrant; provided,
however, that any adjustments that by reason of this Section 14(e) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations shall be made to the nearest cent and to
the nearest one-hundredth of a share, as the case may be.

     (f) Exercise Price Adjustment. Whenever the number of shares of Common
Stock purchasable upon the exercise of any Warrant is adjusted as herein
provided (whether or not the Company then or thereafter elects to issue
additional Warrants in substitution for an adjustment in the number of Shares as
provided in Section 14(h)), the Exercise Price payable upon exercise of such
Warrant shall be adjusted by multiplying such Exercise Price immediately prior
to such adjustment by a fraction, of which the numerator shall be the number of
Shares purchasable upon the exercise of such Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Shares so
purchasable immediately thereafter (calculated, in each case, assuming that the
Company does not elect to issue additional Warrants in substitution for an
adjustment in the number of Shares purchasable upon exercise of a Warrant under
Section 14(h), whether or not the Company does in fact so elect).

     (g) Common Stock: Other Securities. For the purpose of this Section 14, the
term "shares of Common Stock" shall mean (i) the shares of stock designated as
the Common Stock of the Company at the date of this Agreement, or (ii) any other
class of stock resulting from successive changes or reclassification of such
shares consisting solely of changes in par value, or from par value to no par
value, or from no par value to par value. If at any time, as a result of an
adjustment made pursuant to Sections 14(a) or 14(c), the Holders of Warrants
shall become entitled to purchase any shares of the Company other than shares of
Common Stock, thereafter the number of such other shares so purchasable upon
exercise of each Warrant and the applicable Exercise Price of such shares 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 such shares
contained in Section 14(a) through (f), inclusive, above, and the provisions
contained in this Agreement with respect to such shares, shall apply on like
terms to any such other shares.

     (h) Issuance of Additional Warrants in Lieu of Adjustment. The Company may
elect, in its sole discretion, on or after the date of any adjustment required
by Section 14(a), to adjust the number of Warrants in substitution for an
adjustment in the number of Shares purchasable upon the exercise of a Warrant.
Each of the Warrants outstanding after such adjustment of the number of Warrants
shall be exercisable for the same number of Shares as immediately prior to such
adjustment. Each Warrant held of record prior to such adjustment of the number
of Warrants shall become that number of Warrants (calculated to the nearest
one-hundredth) obtained by dividing the applicable Exercise Price in effect
prior to adjustment of such Exercise Price by the applicable Exercise Price in
effect after adjustment of such Exercise Price. The Company shall notify the
Holders of Warrants of its election to adjust the number of Warrants in the same

                                       13

<PAGE>

manner as provided in the first paragraph of Section 16, indicating the record
date for the adjustment, and, if known at the time, the amount of the adjustment
to be made, and shall give prompt written notice thereof to the Warrant Agent.
This record date may be the date on which the Exercise Price is adjusted or any
day thereafter. Upon each adjustment of the number of Warrants pursuant to this
Section 14(h) the Company shall, as promptly as practicable, cause to be
distributed to Holders on such record date Warrant Certificates evidencing,
subject to Section 15, the additional Warrants to which such Holders shall be
entitled as a result of such adjustment, or, at the option of the Company, shall
cause to be distributed to such Holders of record in substitution and
replacement for the Warrant Certificates held by such Holders prior to the date
of adjustment, and upon surrender thereof, if required by the Company, new
Warrant Certificates evidencing all the Warrants to be issued, executed and
registered in the manner specified in Sections 4 and 5 (and which may bear, at
the option of the Company, the applicable adjusted Exercise Price) and shall be
registered in the names of the Holders on the record date specified in the
notice.

     (i) No Dilution or Impairment. The Company will not, by amendment of its
certificate of incorporation or through any consolidation, merger,
reorganization, transfer of assets, dissolution, issue or sale of securities or
any other voluntary action or agreement, avoid or seek to avoid the observance
or performance of any of the terms of this Agreement or the Warrants, but will
at all times in good faith assist in the carrying out of all such terms and in
the taking of all such action as may be necessary or appropriate in order to
protect the rights of the holder of the Warrants against dilution, exercise or
other impairment as described herein.

     (j) Changes to Form of Warrant Certificate. Irrespective of any adjustments
in an Exercise Price or the number or kind of shares of Common Stock purchasable
upon the exercise of the Warrants, Warrants theretofore or thereafter issued may
continue to express the same price and number and kind of shares of Common Stock
as are stated in the Warrants initially issuable pursuant to this Agreement. The
Company, however, may at any time in its sole discretion make any change in the
form of Warrant Certificate that it may deem appropriate to give effect to such
adjustments and that does not affect the substance of the Warrant Certificate
(including the rights, duties or obligations of the Warrant Agent), and any
Warrant Certificate thereafter issued, whether in exchange or substitution for
an outstanding Warrant Certificate or otherwise, may be in the form as so
changed.

     SECTION 15. Fractional Shares. Notwithstanding any adjustment pursuant to
Section 14 in the number of Shares purchasable upon the exercise of a Warrant,
the Company shall not be required to issue fractions of Shares upon exercise of
the Warrants, or to distribute certificates which evidence fractional Shares. If
Warrant Certificates evidencing more than one Warrant shall be surrendered for
exercise at one time by the same Holder, the number of full Shares which shall
be issuable upon exercise thereof shall be computed on the basis of the
aggregate number of Warrants so surrendered. If any fraction of a share of
Common Stock would, except for the provisions of this Section 15, be issuable
upon exercise of any Warrant or Warrants, the Company shall, at its election,
upon the exercise of such Warrant or Warrants, either (a) purchase such fraction
for an amount in cash equal to such fraction of the Market Price (as determined
pursuant to Section 14(b)) of a share of Common Stock, or (b) round up the
number of Shares issued upon exercise of such Warrant or Warrants to the next
whole integer.

                                       14

<PAGE>

     SECTION 16. Notices to Holders of Warrants. Upon any adjustment of the
number of Shares purchasable upon exercise of each Warrant, any Exercise Price
or the number of Warrants outstanding including any adjustment pursuant to
Section 14, the Company, within ten calendar days thereafter, shall (i) cause to
be filed with the Warrant Agent a certificate signed by an Officer setting forth
the event giving rise to such adjustment, such Exercise Price and either the
number of Shares purchasable upon exercise of each Warrant or the additional
number of Warrants to be issued for each previously outstanding Warrant, as the
case may be, after such adjustment and setting forth in reasonable detail the
method of calculation and the facts upon which such adjustment was made, and
(ii) cause the Warrant Agent to give to each of the registered Holders of the
Warrant Certificates at such Holder's address appearing on the Warrant Register,
written notice of such adjustments by first-class mail, postage prepaid. Where
appropriate, such notice may be given in advance and included as a part of the
notice required to be mailed under the other provisions of this Section 16.
Absent manifest error, the Warrant Agent shall be fully protected in relying in
good faith on any such certificate and in making any adjustment described
therein and shall have no duty with respect to, and shall not be deemed to have
knowledge of, any adjustment unless and until it shall have received such a
certificate.

     In case:

     (a) the Company shall order, declare, make or pay any dividend payable in
any securities upon its shares of Common Stock or make any distribution to the
holders of its shares of Common Stock; or

     (b) the Company shall offer to the holders of its shares of Common Stock
any additional shares of Common Stock or securities convertible into shares of
Common Stock or any right to subscribe thereto; or

     (c) of any reclassification of the capital stock of the Company (other than
a subdivision or combination of outstanding shares of Common Stock), or of any
consolidation or merger to which the Company is a party and for which approval
of any stockholders of the Company is required, or of the sale or transfer of
all or substantially all of the assets of the Company, or of any other Organic
Change; or

     (d) there shall be a dissolution, liquidation or winding up of the Company,
or any action is proposed that would result in a Termination Event;

then the Company shall cause prompt written notice of such event to be filed
with the Warrant Agent and shall cause the Warrant Agent to give written notice
of such event to each of the registered Holders of the Warrant Certificates at
such Holder's address appearing on the Warrant Register, by first-class mail,
postage prepaid, such giving of notice and publication to be completed at least
twenty calendar days (or thirty calendar days in the case of a Termination
Event) prior to the date fixed as a record date or the date of closing the
transfer books (or, if no such record date or date of closing of transfer books
is set or required in connection with an event specified in clause (c) or (d)
above, twenty calendar days prior to the consummation of any event specified in
clause (c) or (d) above other than a Termination Event and thirty calendar days
prior to the consummation of any Termination Event) for the determination of the
stockholders

                                       15

<PAGE>

entitled to such dividend, distribution or subscription rights, or
for the determination of stockholders entitled to vote on such proposed merger,
sale or other Organic Change or such dissolution, liquidation or winding up or
Termination Event. Such notice shall specify such record date or the date of
closing the transfer books (or the anticipated date of the event, if no such
record date or date of closing of transfer books is set or required in
connection with an event specified in clause (c) or (d) above), as the case may
be. No notice of a Termination Event shall be deemed to be an assurance that the
underlying transaction will be completed, and any such notice may set forth,
without limitation, the contingencies to which any such transaction is subject.
The failure to give the notice required by this Section 16 or any defect therein
shall not affect the legality or validity of any distribution, right, warrant,
dissolution, liquidation or winding up or the vote upon or any other action
taken in connection therewith, but, notwithstanding any other provision hereof,
no termination of the Warrants as a result of any Termination Event shall be
effective until at least thirty calendar days after the notice of the
Termination Event shall have been given.

     SECTION 17. Warrant Agent. The Warrant Agent undertakes only the duties and
obligations expressly imposed by this Agreement and the Warrant Certificate, in
each case upon the following terms and conditions, by all of which the Company
and the Holders of Warrants, by their acceptance thereof, shall be bound:

     (a) The statements contained herein and in the Warrant Certificates shall
be taken as statements of the Company, and the Warrant Agent assumes no
responsibility for the accuracy of any of the same except such as describe the
Warrant Agent or action taken or to be taken by it. Except as otherwise provided
herein, the Warrant Agent assumes no responsibility with respect to the
execution, delivery or distribution of the Warrant Certificates.

     (b) The Warrant Agent shall not be responsible for any failure of the
Company to comply with any of the covenants contained in this Agreement or in
the Warrant Certificates to be complied with by the Company, nor shall it at any
time be under any duty or responsibility to any Holder of a Warrant to make or
cause to be made any adjustment in any Exercise Price or in the number of Shares
issuable upon exercise of any Warrant (except as instructed by the Company), or
to determine whether any facts exist that may require any such adjustments, or
with respect to the nature or extent of or method employed in making any such
adjustments when made.

     (c) The Warrant Agent may consult at any time with counsel satisfactory to
it (who may also be counsel for the Company), and the Warrant Agent shall incur
no liability or responsibility to the Company or any Holder of any Warrant
Certificate in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with the opinion or the advice of such counsel,
absent gross negligence, bad faith or willful misconduct (each as determined by
a final order, judgment, ruling or decree of a court of competent jurisdiction)
in the selection and continued retention of such counsel and the reliance on
such counsel's advice.

     (d) The Warrant Agent shall incur no liability or responsibility to the
Company or to any Holder of any Warrant Certificate for any action taken in
reliance on any notice, resolution,

                                       16

<PAGE>

waiver, consent, order, certificate or other paper, document or instrument
believed by it to be genuine and to have been signed, sent or presented by the
proper party or parties.

     (e) The Company agrees to pay to the Warrant Agent reasonable compensation
for all services rendered by the Warrant Agent under this Agreement, to
reimburse the Warrant Agent upon demand for all reasonable expenses, taxes and
governmental charges and other charges of any kind and nature incurred by the
Warrant Agent in the preparation, administration, delivery, execution and
amendment of this Agreement and the performance of its duties under this
Agreement and to indemnify the Warrant Agent and save it harmless against any
and all losses, liabilities and reasonable expenses, including judgments,
damages, fines, penalties, claims, demands, settlements, costs and reasonable
counsel fees and expenses, for anything done or omitted by the Warrant Agent
arising out of or in connection with this Agreement except as a result of its
gross negligence, bad faith or willful misconduct (each as determined by a final
order, judgment, ruling or decree of a court of competent jurisdiction). The
reasonable costs and expenses incurred by the Warrant Agent in enforcing the
right to indemnification shall be paid by the Company unless it is determined by
a final order, judgment, decree or ruling of a court of competent jurisdiction
that the Warrant Agent is not entitled to indemnification due to its gross
negligence, bad faith or willful misconduct.

     (f) The Warrant Agent shall be under no obligation to institute any action,
suit or legal proceeding or to take any other action likely to involve expense
unless the Company or one or more registered Holders of Warrant Certificates
furnishes the Warrant Agent with reasonable security and indemnity for any costs
or expenses that may be incurred. All rights of action under this Agreement or
under any of the Warrants may be enforced by the Warrant Agent without the
possession of any of the Warrant Certificates or the production thereof at any
trial or other proceeding relative thereto, and any such action, suit or
proceeding instituted by the Warrant Agent shall be brought in its name as
Warrant Agent, and any recovery or judgment shall be for the ratable benefit of
the registered Holders of the Warrants, as their respective rights or interests
may appear.

     (g) The Warrant Agent, and any stockholder, affiliate, director, officer or
employee thereof, may buy, sell or deal in any of the Warrants or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company is interested, or contract with or lend money to the Company
or otherwise act as fully and freely as though it was not the Warrant Agent
under this Agreement, or a stockholder, director, officer or employee of the
Warrant Agent, as the case may be. Nothing herein shall preclude the Warrant
Agent from acting in any other capacity for the Company or for any other legal
entity.

     (h) The Warrant Agent shall act hereunder solely as agent for the Company,
and its duties shall be determined solely by the provisions hereof. The Warrant
Agent shall not be liable for anything that it may do or refrain from doing in
connection with this Agreement except in connection with its own gross
negligence, bad faith or willful misconduct (each as determined by a final
order, judgment, decree or ruling of a court of competent jurisdiction). In no
event will the Warrant Agent be liable for special, indirect, incidental,
punitive or consequential loss or damage of any kind whatsoever, even if the
Warrant Agent has been advised of the possibility of such

                                       17

<PAGE>

loss or damage. Any liability of the Warrant Agent under this Agreement to the
Company will be limited to the amount of fees paid by the Company to the Warrant
Agent.

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

     (j) The Warrant Agent shall not be under any responsibility in respect of
the validity of this Agreement or the execution and delivery hereof (except the
due and validly authorized execution hereof by the Warrant Agent) or in respect
of the validity or execution of any Warrant Certificate (except its due and
validly authorized countersignature thereof), nor shall the Warrant Agent by any
act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of the Shares to be issued pursuant to this
Agreement or any Warrant Certificate or as to whether the Shares will when
issued be validly issued, fully paid and nonassessable or as to the Exercise
Price or the number of Shares issuable upon exercise of any Warrant.

     (k) The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from an
Officer or any Vice President, the Treasurer, the Secretary or an Assistant
Secretary of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and such instructions shall be full
authorization and protection to the Warrant Agent and the Warrant Agent shall
not be liable for any action taken, suffered to be taken, or omitted to be taken
by it in good faith in accordance with instructions of any such officer or in
good faith reliance upon any statement signed by any one of such officers of the
Company with respect to any fact or matter (unless other evidence in respect
thereof is herein specifically prescribed) which may be deemed to be
conclusively proved and established by such signed statement.

     (l) No provision of this Agreement shall require the Warrant Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or in the exercise of its rights if
it believes that repayment of such funds or adequate indemnification against
such risk or liability is not reasonably assured to it.

     (m) If the Warrant Agent shall receive any notice or demand (other than
notice of or demand for exercise of Warrants) addressed to the Company by the
Holder of the Warrant Certificates pursuant to the provisions of the Warrant
Certificates, the Warrant Agent shall promptly forward such notice or demand to
the Company.

     (n) The provisions of this Section 17 shall survive the termination of this
Agreement, the exercise or expiration of the Warrants and the resignation or
removal of the Warrant Agent.

     SECTION 18. Change of Warrant Agent. If the Warrant Agent resigns (such
resignation to become effective not earlier than ninety calendar days after the
giving of written notice thereof to the Company and the registered Holders of
Warrant Certificates) or shall be adjudged a bankrupt or insolvent, or shall
file a voluntary petition in bankruptcy or make an assignment for

                                       18

<PAGE>

the benefit of its creditors or consent to the appointment of a receiver of all
or any substantial part of its property or affairs or shall generally not pay
its debts as such debts become due, or shall admit in writing its inability to
pay or meet its debts generally as they become due, or if an order of any court
shall be entered approving any petition filed by or against the Warrant Agent
under the provisions of bankruptcy laws or any similar legislation, or if a
receiver, trustee or other similar official of it or of all or any substantial
part of its property shall be appointed, or if any public officer shall take
charge or control of it or of its property or affairs, for the purpose of
rehabilitation, conservation, protection, relief, winding up or liquidation, or
becomes incapable of acting as Warrant Agent or if the Board of Directors by
resolution removes the Warrant Agent (such removal to become effective not
earlier than thirty calendar days after the filing of a certified copy of such
resolution with the Warrant Agent and the giving of written notice of such
removal to the registered holders of Warrant Certificates), the Company shall
appoint a successor to the Warrant Agent. If the Company fails to make such
appointment within a period of thirty calendar days after such removal or after
it has been so notified in writing of such resignation or incapacity by the
Warrant Agent or by the registered Holder of a Warrant Certificate (in the case
of incapacity), then the registered Holder of any Warrant Certificate may apply
to any court of competent jurisdiction for the appointment of a successor to the
Warrant Agent. Pending appointment of a successor to the Warrant Agent, either
by the Company or by such a court, the duties of the Warrant Agent shall be
carried out by the Company. Any successor Warrant Agent, whether appointed by
the Company or by such a court, shall be a bank or trust company, in good
standing, incorporated under the laws of any state or of the United States of
America, and authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by federal or state authority and having a
combined capital and surplus of not less than $25,000,000. The combined capital
and surplus of any such successor Warrant Agent shall be deemed to be the
combined capital and surplus as set forth in the most recent report of its
condition published prior to its appointment pursuant to law or to the
requirements of a federal or state supervising or examining authority. As soon
as practicable after appointment of the successor Warrant Agent, the Company
shall cause written notice of the change in the Warrant Agent to be given to
each of the registered Holders of the Warrant Certificates at such Holder's
address appearing on the Warrant Register. After appointment, the successor
Warrant Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Warrant Agent without
further act or deed. The former Warrant Agent shall deliver and transfer to the
successor Warrant Agent any property at the time held by it hereunder and
execute and deliver, at the expense of the Company, any further assurance,
conveyance, act or deed necessary for these purposes. Failure to give any notice
provided for in this Section 18 or any defect therein shall not affect the
legality or validity of the removal of the Warrant Agent or the appointment of a
successor Warrant Agent, as the case may be.

     SECTION 19. Merger, Consolidation or Change of Name of Warrant Agent. Any
person into which the Warrant Agent may be merged or converted or with which it
may be consolidated, or any person resulting from any merger, conversion or
consolidation to which the Warrant Agent is a party, or any person succeeding to
the shareholder services business of the Warrant Agent, shall be the successor
to the Warrant Agent hereunder without the execution or filing of any document
or any further act on the part of any of the parties hereto, if such person
would be eligible for appointment as a successor Warrant Agent under the
provisions of Section 18. If any of the Warrant Certificates have been
countersigned but not delivered at the

                                       19

<PAGE>

time such successor to the Warrant Agent succeeds under this Agreement, any such
successor to the Warrant Agent may adopt the countersignature of the original
Warrant Agent; and if at that time any of the Warrant Certificates shall not
have been countersigned, any successor to the Warrant Agent may countersign such
Warrant Certificates either in the name of the predecessor Warrant Agent or in
the name of the successor Warrant Agent; and in all such cases such Warrant
Certificates shall have the full force provided in the Warrant Certificates and
in this Agreement.

     If at any time the name of the Warrant Agent is changed and at such time
any of the Warrant Certificates have been countersigned but not delivered, the
Warrant Agent whose name has changed may adopt the countersignature under its
prior name; and if at that time any of the Warrant Certificates have not been
countersigned, the Warrant Agent may countersign such Warrant Certificates
either in its prior name or in its changed name; and in all such cases such
Warrant Certificates shall have the full force provided in the Warrant
Certificates and in this Agreement.

     SECTION 20. Miscellaneous.

     (a) Warrantholder Not Deemed a Stockholder. Nothing contained in this
Agreement or in any of the Warrant Certificates shall be construed as conferring

the election of directors of the Company or any other matter, or any rights
whatsoever as stockholders of the Company.

     (b) Notices to Company and Warrant Agent. Any notice or demand authorized

Company by the Holder of a Warrant Certificate pursuant to the provisions of the
Warrant Certificates, the Warrant Agent shall promptly forward such notice or

Warrant Agent for the payment of, all taxes and charges that may be imposed by
the United States or any state upon the Company or the Warrant Agent in
connection with the issuance or delivery of Shares upon the exercise of any
Warrants, but any taxes or charges in connection with the issuance of Warrant
Certificates or certificates for Shares in any name other than that of the
registered Holder of the Warrant Certificate surrendered shall be paid by such
registered Holder; and, in such case, the Company shall not be required to issue
or deliver any Warrant Certificate or certificate for Shares until such taxes or
charges shall have been paid or it has been established to the Company's
satisfaction that no tax or charge is due. The Warrant Agent shall have no duty
or obligation under this Section 20(c) unless and until it is satisfied that all
such taxes and/or charges have been paid.

     (d) Entire Agreement; Amendments. This Agreement constitutes the entire
agreement and supersedes all other prior agreements and understandings, both
written and oral, among the parties, or any of them, with respect to the subject
matter hereof. This Agreement may not be amended or supplemented and no
provision hereof may be waived, except in a writing signed by both the Company
and the Warrant Agent and with the prior written consent of Holders of the
Warrants exercisable for a majority of the Shares then issuable upon exercise of
the Warrants then outstanding; provided, however, that the Company and the
Warrant Agent may from time to time supplement or amend this Agreement without
the approval of any Holders of Warrant Certificates in order to cure any
ambiguity, manifest error or other mistake in this Agreement, or to correct or
supplement any provision contained herein that may be defective or inconsistent
with any other provision herein, or to make any other provisions in regard to
matters or questions arising hereunder that the Company and the Warrant Agent
may deem necessary or desirable and that shall not adversely affect, alter or
change the interests of the Holders of the Warrants; and provided, further, that
each amendment or supplement that decreases the Warrant Agent's rights or
increases its duties and responsibilities hereunder shall also require the prior
written consent of the Warrant Agent. Notwithstanding any of the foregoing, the
Company may not increase the Exercise Price, shorten the duration of the
Warrants, or change the securities or other property for which Warrants are
exercisable without the consent of each of the Holders affected thereby.

or cause to be paid any consideration, whether by way of fee or otherwise, to

                    [FORM OF REVERSE OF WARRANT CERTIFICATE]

                             CHART INDUSTRIES, INC.

     The Warrants evidenced by this Warrant Certificate are a part of a duly
authorized issue of Warrants to purchase a maximum of 280,281 shares (as
adjusted from time to time) of Common Stock issued pursuant to that certain
Warrant Agreement, dated as of September 15, 2003 (the "Warrant Agreement"),
duly executed and delivered by the Company and National City Bank, as Warrant
Agent (the "Warrant Agent"). The Warrant Agreement hereby is incorporated by
reference in and made a part of this instrument and is hereby referred to for a
description of the rights, limitation of rights, obligations, duties and
immunities thereunder of the Warrant Agent, the Company and the Holders (the
words "Holders" or "Holder" meaning the registered holders or registered holder)
of the Warrants. A copy of the Warrant Agreement may be inspected at the Warrant
Agent Office and is available upon written request addressed to the Company. All
capitalized terms used herein but not defined that are defined in the Warrant
Agreement shall have the meanings assigned to them therein.

     Warrants may be exercised to purchase Shares from the Company from the
Consummation Date through the Expiration Time, at the Exercise Price set forth
on the face hereof, subject to adjustment as described in the Warrant Agreement.
Subject to the terms and conditions set forth herein and in the Warrant
Agreement, the Holder of the Warrants evidenced by this Warrant Certificate may
exercise such Warrant by:

          (i) providing a Warrant Exercise Notice to the Warrant Agent at the
address set forth in the Warrant Agreement, "Re: Chart Industries, Inc. Warrant
Exercise", by certified mail, return receipt requested, by nationally recognized
overnight courier service, by hand or by facsimile, no later than the Expiration
Time, which Warrant Exercise Notice shall be in the form of an election to
purchase Shares of Common Stock of the Company substantially in the form set
forth in Exhibit B to the Warrant Agreement, properly completed and executed by
the Holder;

          (ii) delivering no later than 5:00 p.m., Eastern Time, on the business
day immediately prior to the Settlement Date, the Warrant Certificates
evidencing such Warrants to the Warrant Agent; and

          (iii) paying the applicable Exercise Amount, together with any
applicable taxes and governmental charges (a) in cash (including by wire
transfer in immediately available funds to an account designated by the
Company), (b) by an official bank check or cashier's check, (c) by Cashless
Exercise, or (d) by any combination of the foregoing.

     The Exercise Amount shall be payable by wire transfer in immediately
available funds of the Exercise Amount to an account of the Warrant Agent
specified in writing by the Warrant Agent for such purpose or by delivery of an
official bank check or cashier's check in immediately available funds of the
Exercise Amount to the Warrant Agent at its corporate office,

                                      A-R-1

<PAGE>

no later than 5:00 p.m., Eastern Time, on the business day immediately prior to
the Settlement Date. The initial Exercise Price shall be $32.97.

     In the event that upon any exercise of the Warrants evidenced hereby the
number of Shares actually purchased shall be less than the total number of
Shares purchasable upon exercise of the Warrants evidenced hereby, there shall
be issued to the holder hereof, or such holder's assignee, a new Warrant
Certificate evidencing the Warrants to purchase the Shares not so purchased. No
adjustment shall be made for any cash dividends on any Shares issuable upon
exercise of this Warrant. After the Expiration Time, unexercised Warrants shall
become wholly void and of no value.

     The Company shall not be required to issue fractions of Shares or any
certificates that evidence fractional Shares. If any fraction of a share of
Common Stock would, except for the provisions of the preceding sentence, be
issuable upon exercise of any Warrant or Warrants, the Company shall, at its
election, either (i) purchase such fraction for an amount in cash equal to such
fraction of the Market Price (as defined in the Warrant Agreement) of a share of
Common Stock or (ii) round up the number of Shares issued upon exercise of such
Warrant or Warrants to the next whole integer.

     Warrant Certificates, when surrendered at the Warrant Agent Office by the
Holder thereof in person or by a legal representative or attorney duly
authorized in writing, or by mail may be exchanged, in the manner and subject to
the limitations provided in the Warrant Agreement, but without payment of any
service charge, for another Warrant Certificate or Warrant Certificates of like
tenor evidencing Warrants to purchase in the aggregate a like number of Shares.

     No Warrants may be sold, exchanged or otherwise transferred in violation of
the Securities Act or state securities laws. The Company or the Warrant Agent
may require that, to the extent reasonable as a condition to any sale, exchange
or transfer of a Warrant that the holder deliver to the Company and the Warrant
Agent an opinion of counsel, which opinion of counsel shall be reasonably
satisfactory to the Company, to the effect that such sale, exchange or transfer
is made in compliance with the Securities Act and all applicable state
securities laws or pursuant to an exempt transaction under the Securities Act
and such state securities laws. The provisions of this paragraph shall not apply
to the exercise of any Warrants to the extent that the Shares issued upon such
exercise (and any unexercised portion of the Warrant so exercised) shall be
issued to the same Holder that exercised such Warrants.

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