Ladies and Gentlemen:

          Chart Industries, Inc., a corporation organized under the laws of Delaware (the “Company”),
proposes to issue and sell to the several Underwriters named in Schedule I hereto (the
“Underwriters”), 12,500,000 shares of the common stock, par value $0.01 per share, of the Company
(the “Firm Shares”).

          The Company also proposes to issue and sell to the several Underwriters not more than an
additional 1,875,000 shares of common stock, par value $0.01 per share, of the Company (the
“Additional Shares”) if and to the extent that Morgan Stanley & Co. Incorporated (“Morgan
Stanley”), Lehman Brothers Inc. (“Lehman”) and UBS Securities LLC (“UBS,” together with Morgan
Stanley and Lehman, the “Managers”), as Managers of the offering, shall have determined to
exercise, on behalf of the Underwriters, the right to purchase such shares of common stock granted
to the Underwriters in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter
collectively referred to as the “Shares.” The shares of common stock, par value $0.01 per share,
of the Company to be outstanding after giving effect to the sales contemplated hereby are
hereinafter referred to as the “Common Stock.”

          The Company has filed with the Securities and Exchange Commission (the “Commission”) a
registration statement, including a prospectus, relating to the Shares. The registration statement
as amended at the time it becomes effective, including the information (if any) deemed to be part
of the registration statement at the time of effectiveness pursuant to Rule 430A under the
Securities Act of 1933, as amended (the “Securities Act”), is hereinafter

 

 

referred to as the “Registration Statement”; the prospectus in the form first used to confirm
sales of Shares (or in the form first made available to the Underwriters by the Company to meet
requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as
the “Prospectus.” If the Company has filed an abbreviated registration statement to register
additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462
Registration Statement”), then any reference herein to the term “Registration Statement” shall be
deemed to include such Rule 462 Registration Statement.

          For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule
405 under the Securities Act; “Time of Sale Prospectus” means the preliminary prospectus included
in the Registration Statement at the time it became effective, together with the free writing
prospectuses, if any, or any other pricing information identified or included in Schedule II
hereto; and “broadly available road show” means a “bona fide electronic road show,” if any, as
defined in Rule 433(h)(5) under the Securities Act that has been made available without restriction
to any person.

          Morgan Stanley has agreed to reserve a portion of the Shares to be purchased by it under this
Agreement for sale to the Company’s directors, officers, employees and business associates and
other parties related to the Company (collectively, “Participants”), as set forth in the Time of
Sale Prospectus and the Prospectus under the heading “Underwriting” (the “Directed Share Program”).
The Shares to be sold by Morgan Stanley and its affiliates pursuant to the Directed Share Program
are referred to hereinafter as the “Directed Shares”. Any Directed Shares not orally or
electronically confirmed for purchase by any Participant by the end of the day on which this
Agreement is executed will be offered to the public by the Underwriters as set forth in the Time of
Sale Prospectus and the Prospectus.

          1. Representations and Warranties. The Company represents and warrants to each
Underwriter as set forth below in this Section 1:

          (a) The Registration Statement has become effective; no stop order suspending the
effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are
pending before or threatened by the Commission.

          (b) (i) The Registration Statement, when it became effective, did not contain and, as amended
or supplemented, if applicable, will not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the statements therein
not misleading, (ii) the Registration Statement and the Prospectus comply and, as amended or
supplemented, if applicable, will comply in all material respects with the Securities Act and the
applicable rules and regulations of the Commission thereunder, (iii) the Time of Sale Prospectus

Prospectus is not yet available to prospective purchasers and at the Closing Date (as defined in
Section 4), the Time of Sale Prospectus, as then amended or supplemented by the Company, if
applicable, will not, contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements therein, in the light of the circumstances under which they
were made, not misleading, (iv) each broadly available road show, if any, when

-2-

 

considered together with the Time of Sale Prospectus, does not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading and (v) the Prospectus does
not, as of its date, contain and, as then amended or supplemented, if applicable, will not contain
any untrue statement of a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading;
provided, however, that the Company makes no representation or warranty as to the
information contained in or omitted from the Registration Statement, the Time of Sale Prospectus or
the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with
information furnished in writing to the Company by or on behalf of the Underwriters through the
Managers specifically for inclusion therein.

          (c) The Company is not an “ineligible issuer” in connection with the offering pursuant to
Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is
required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with
the Commission in accordance with the requirements of the Securities Act and the applicable rules
and regulations of the Commission thereunder. Each free writing prospectus that the Company has
filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was
prepared by or on behalf of or used or referred to by the Company complies or will comply in all
material respects with the requirements of the Securities Act and the applicable rules and
regulations of the Commission thereunder. Except for the free writing prospectuses or other
pricing information, if any, identified or included in Schedule II hereto, and broadly available
road shows, if any, furnished to you before first use, the Company has not prepared, used or
referred to, and will not, without your prior consent, prepare, use or refer to, any free writing
prospectus or any notice, circular, advertisement, letter or other communication published or
transmitted pursuant to Rule 134 of the Securities Act.

          (d) The Company is not, and after giving effect to the offering and sale of the Shares and the
application of the proceeds thereof as described in the Prospectus will not be, an “investment
company” as defined in the Investment Company Act, without taking account of any exemption arising
out of the number of holders of the Company’s securities.

          (e) The Company has not paid or agreed to pay to any person any compensation for soliciting
another to purchase any securities of the Company (except as contemplated in this Agreement).

          (f) Neither the Company nor any of its subsidiaries has taken or will take, directly or
indirectly, any action designed to or that has constituted or that would reasonably be expected to
cause or result, under the Exchange Act or otherwise, in unlawful stabilization or manipulation of
the price of any security of the Company to facilitate the sale or resale of the Shares.

          (g) The Company and each of its “significant subsidiaries” (as defined in Regulation S-X under
the Securities Act) has been duly incorporated or formed and is validly existing as an entity in
good standing under the laws of the jurisdiction in which it is chartered or

-3-

 

organized with full corporate or other organizational power and authority to own or lease, as
the case may be, and to operate its properties and conduct its business as described in the Time of
Sale Prospectus and the Prospectus, and is duly qualified to do business as a foreign corporation
or other entity and is in good standing under the laws of each jurisdiction where the ownership or
leasing of its properties or the conduct of its business requires such qualification except where
the failure to be so incorporated or formed or existing or qualified, have such power or authority
or be in good standing would not reasonably be expected to have a material adverse effect on the
condition (financial or other), business, properties or results of operations of the Company and
its subsidiaries, taken as a whole (a “Material Adverse Effect”). The Company’s “significant
subsidiaries” are listed on Schedule III hereto.

          (h) All the outstanding shares of capital stock, membership interests and limited partnership
interests, as applicable, of each significant subsidiary of the Company have been duly authorized
and validly issued and are fully paid and nonassessable, and, except as otherwise set forth in the
Time of Sale Prospectus and the Prospectus, all outstanding shares of capital stock, membership
interests and limited partnership interests, as applicable, of each significant subsidiary of the
Company are owned by the Company either directly or through wholly owned subsidiaries free and
clear of any security interest, claim, lien or encumbrance (other than liens, encumbrances and
restrictions imposed in favor of the lenders under the Company’s existing senior secured credit
facility described in the Time of Sale Prospectus and the Prospectus or permitted thereunder).

          (i) (a) This Agreement has been duly authorized, executed and delivered by the Company; (b)
the shares of Common Stock outstanding prior to the issuance of the Shares to be sold by the
Company have been duly authorized and are validly issued, fully paid and non-assessable; and (c)
the Shares to be sold by the Company have been duly authorized and, when issued and delivered in
accordance with the terms of this Agreement, will be validly issued, fully paid and non-assessable,
and the issuance of such Shares will not be subject to any preemptive or similar rights.

          (j) The authorized capital stock of the Company conforms as to legal matters to the
description thereof contained in the Time of Sale Prospectus and the Prospectus.

          (k) No consent, approval, authorization, filing with or order of any court or governmental
agency or body is required in connection with the execution, delivery and performance of this
Agreement (including without limitation the issuance of the Shares), except such (i) as may be
required under the blue sky laws of any jurisdiction in which the Shares are offered and sold or
(ii) as shall have been obtained or made prior to the Closing Date.

          (l) None of the execution and delivery of this Agreement, the issuance and sale of the Shares
or the consummation of any of the transactions herein contemplated will conflict with or result in
a breach or violation or imposition of any lien, charge or encumbrance upon any property or assets
of the Company or any of its subsidiaries pursuant to (i) the charter or bylaws or other
organizational document of the Company or any of its significant subsidiaries; (ii) the terms of
any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other

-4-

 

agreement, obligation, condition, covenant or instrument to which the Company or any of its
significant subsidiaries is a party or bound or to which its or their property is subject; or (iii)
any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having jurisdiction over
the Company or any of its significant subsidiaries or any of its or their properties other than in
the case of clauses (ii) and (iii), such conflicts, breaches, violations, liens, charges or
encumbrances that would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

          (m) The consolidated historical financial statements of the Company (including those of the
predecessor company and the reorganized company) included in the Time of Sale Prospectus, the
Prospectus and the Registration Statement present fairly the financial condition, results of
operations and cash flows of the Company as of the dates and for the periods indicated, comply as
to form with the applicable accounting requirements of the Securities Act and have been prepared in
conformity with generally accepted accounting principles in the United States applied on a
consistent basis throughout the periods involved (except as otherwise noted therein); the selected
financial data set forth under the captions “Summary Historical and Pro Forma Financial
Information” and “Selected Historical Consolidated Financial Data” in the Time of Sale Prospectus,
the Prospectus and the Registration Statement fairly present, on the basis stated in the Time of
Sale Prospectus, the Prospectus and the Registration Statement, the information included therein;
the unaudited pro forma financial statements included in the Time of Sale Prospectus, the
Prospectus and the Registration Statement include assumptions that provide a reasonable basis for
presenting the significant effects directly attributable to (i) the Acquisition (as defined in the
Time of Sale Prospectus and the Prospectus) and the transactions related to the Acquisition, as
described in the Time of Sale Prospectus and the Prospectus, (ii) the offering of the Company’s 9
1/8% senior subordinated notes due 2015 and the borrowings under the Company’s senior secured
credit facility and (iii) the offering of the Shares; the related pro forma adjustments give
appropriate effect to those assumptions; and the pro forma financial information reflects the
proper application of those adjustments to the historical financial statement amounts in the
unaudited pro forma financial statements included in the Time of Sale Prospectus, the Prospectus
and the Registration Statement. The unaudited pro forma financial statements included under the
captions “Summary Historical and Pro Forma Financial Information” and “Unaudited Pro Forma
Financial Information” in the Time of Sale Prospectus, the Prospectus and the Registration
Statement comply as to form in all material respects with the applicable accounting requirements of

          (n) No action, suit or proceeding by or before any court or governmental agency, authority or
body or any arbitrator involving the Company or any of its subsidiaries or its or their property is
pending or, to the best knowledge of the Company, threatened that (i) would reasonably be expected
to have a Material Adverse Effect on the performance of this Agreement or the consummation of any
of the transactions contemplated hereby or (ii) would reasonably be expected to have a Material
Adverse Effect, except as set forth in or contemplated in the Time of Sale Prospectus and the
Prospectus (exclusive of any amendment or supplement thereto).

necessary to the conduct of its operations as presently conducted except as would not reasonably be
expected to have a Material Adverse Effect.

provision of its charter or bylaws or any equivalent organizational document; (ii) the terms of any
indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other
agreement, obligation, condition, covenant or instrument to which it is a party or bound or to
which its property is subject; or (iii) any statute, law, rule, regulation, judgment, order or
decree applicable to the Company or any of its subsidiaries of any court, regulatory body,
administrative agency, governmental body, arbitrator or other authority having jurisdiction over
the Company or such subsidiary or any of its properties, as applicable, other than in the cases of
clauses (ii) and (iii), such violations and defaults that would not reasonably be expected to have
a Material Adverse Effect.

assessment, fine or penalty levied against it, to the extent that any of the foregoing is due and

faith or as would not reasonably be expected to have a Material Adverse Effect and except as set
forth in or contemplated in the Time of Sale Prospectus and the Prospectus (exclusive of any
amendment or supplement thereto).

exists or, to the Company’s knowledge, is threatened or imminent, and the Company is not aware of
any existing or imminent labor disturbance by its employees or any of its or its subsidiaries’

Material Adverse Effect, and neither the Company nor any of its subsidiaries has received any
notice of proceedings relating to the revocation or modification of any such certificate,
authorization or permit which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, would have a Material Adverse Effect, except as set forth in or

          2. Agreements to Sell and Purchase. The Company hereby agrees to sell to the several

Shares set forth in Schedule I hereto opposite its name.

“Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number
of Additional Shares (subject to such adjustments to eliminate fractional shares as you may
determine) that bears the same proportion to the total number of Additional Shares to be purchased
on such Option Closing Date as the number of Firm Shares set forth in Schedule I hereto opposite
the name of such Underwriter bears to the total number of Firm Shares.

          The Company hereby agrees that, without the prior written consent of the Managers on behalf of
the Underwriters, it will not, during the period ending 180 days after the date of the Prospectus,

-9-

 

other arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of the Common Stock, whether any such transaction described in clause (i)
or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or
otherwise or (iii) file any registration statement with the Commission (other than a registration
statement on Form S-8) relating to the offering of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock.

          The restrictions contained in the preceding paragraph shall not apply to (A) the Shares to be

or joint venture with, another company; provided that in the case of any transfer,
distribution or issuance pursuant to clause (D), (i) each distributee or recipient shall sign and

the recipient shall not be required to, and shall not voluntarily, file a report under the Exchange
Act, reporting a reduction in beneficial ownership of shares of Common Stock during the restricted
period referred to in the preceding paragraph.

          The Company also agrees and consents to the entry of stop transfer instructions with the
Company’s transfer agent and registrar against the transfer of shares of Common Stock except in
compliance with the foregoing restrictions.

          3. Terms of Public Offering. The Company is advised by you that the Underwriters

reasonably request no later than 5:00 p.m., New York City time, on the day immediately following
the date hereof.

          (b) The Company will not make any amendment or supplement to the Time of Sale Prospectus or
the Prospectus without the prior written consent of the Managers (not to be unreasonably withheld
or delayed).

          (c) The Company will furnish each Underwriter a copy of each proposed free writing prospectus
to be prepared by or on behalf of, used by, or referred to by the Company and shall not use or
refer to any proposed free writing prospectus to which the Underwriters reasonably object.

          (d) The Company will not take any action that would result in an Underwriter or the Company
being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free
writing prospectus or Company information prepared by or on behalf of the Underwriter that the
Underwriter otherwise would not have been required to file thereunder.

          (e) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time
when the Prospectus is not yet available to prospective purchasers and any event shall occur or
condition exist as a result of which, in the opinion of counsel for the Underwriters or counsel for
the Company, it is necessary to amend or supplement the Time of Sale Prospectus in order to make
the statements therein, in the light of the circumstances, not misleading, or if any event shall
occur or condition exist as a result of which, in the opinion of counsel for the Underwriters or
counsel for the Company, the Time of Sale Prospectus conflicts with the information contained in
the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters or
counsel for the Company, it is necessary to amend or supplement the Time of Sale Prospectus to
comply with applicable law, the Company will promptly prepare, file with the Commission and
furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments
or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus
as so amended or supplemented will not, in the light of the circumstances when delivered to a
prospective purchaser, be misleading or so that the Time of

-11-

 

Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration
Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with
applicable law.

          (f) If at any time when a prospectus (or in lieu thereof the notice referred to in Rule 173(a)
under the Securities Act) relating to the Shares is required to be delivered under the Securities
Act, any event occurs as a result of which, in the opinion of counsel for the Underwriters and
counsel for the Company, it is necessary to amend or supplement the Prospectus, as then amended or
supplemented, (i) in order that the Prospectus would not include any untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading, or (ii) to comply with applicable
law, the Company will promptly (A) notify the Underwriters of any such event; (B) subject to the
requirements of paragraph (b) of this Section 5, prepare an amendment or supplement that will
correct such statement or omission or effect such compliance; and (C) supply any supplemented or
amended Prospectus to the several Underwriters and counsel for the Underwriters without charge in
such quantities as they may reasonably request.

          (g) The Company will arrange, if necessary, for the qualification of the Shares for sale by
the Underwriters under the laws of such jurisdictions as the Underwriters may designate and will
maintain such qualifications in effect so long as required for the sale of the Shares;
provided that in no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action that would subject it to
service of process in suits, other than those arising out of the offering or sale of the Shares, in
any jurisdiction where it is not now so subject or to subject itself to taxation in excess of a
nominal amount in respect of doing business in any jurisdiction. The Company will promptly advise
the Underwriters of the receipt by the Company of any notification with respect to the suspension
of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of
any proceeding for such purpose.

          (h) The Company will not take, directly or indirectly, any action designed to or which has
constituted or which might reasonably be expected to cause or result, under the Exchange Act or
otherwise, in unlawful stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of the Shares.

          (i) The Company agrees to pay the costs and expenses relating to the following matters: (i)
the preparation, printing (or reproduction), delivery (including postage, air freight charges and
charges for counting and packaging) and filing of copies of any preliminary prospectus, the Time of
Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by
or referred to by the Company and the Registration Statement, and all amendments or supplements to
any of the foregoing, as may, in each case, be reasonably requested for use in connection with the
offering and sale of the Shares; (ii) any stamp or transfer taxes in connection with the original
issuance, sale and delivery of the Shares; (iii) the printing (or reproduction) and delivery of
this Agreement and any blue sky memorandum delivered to investors in connection with the offering
of the Shares; (iv) any registration or qualification of the Shares for offer and sale under the
securities or blue sky laws of the several states and any other

-12-

 

jurisdictions specified pursuant to Section 5(g) (including filing fees and the reasonable
fees relating to such registration and qualification and expenses of one counsel for the
Underwriters in each jurisdiction in which such registration and qualification is required); (v)
all filing fees and the reasonable fees and disbursements of one counsel to the Underwriters
incurred in connection with the review and qualification of the offering of the Shares by the
National Association of Securities Dealers, Inc.; (vi) all fees and expenses in connection with the
preparation and filing of the registration statement on Form 8-A relating to the Common Stock and
all costs and expenses incident to listing the Shares on the Nasdaq National Market, (vii) the cost
of printing certificates representing the Shares; (viii) the costs and charges of any transfer
agent, registrar or depositary; (ix) the transportation and other expenses (collectively, the “Road
Show Expenses”) incurred by or on behalf of the representatives of the Company in connection with
presentations to prospective purchasers of the Shares; (x) the fees and expenses of the Company’s
accountants and the fees and expenses of counsel (including local and special counsel) for the
Company; (xi) all fees and disbursements of counsel incurred by the Underwriters in connection with
the Directed Share Program and stamp duties, similar taxes or duties or other taxes, if any,
incurred by the Underwriters in connection with the Directed Share Program; and (xii) all other
costs and expenses incident to the performance by the Company of their obligations hereunder;
provided, however, that the Underwriters will pay one-half of the Road Show Expenses
including one-half of the cost of any chartered aircraft used in connection with presentations to
prospective purchasers of the Shares.

          (j) The Company will use its best efforts to cause the Registration Statement, if not
effective at the Execution Time, and any amendment thereof, to become effective. Prior to the
termination of the offering of the Shares, the Company will not file any amendment of the
Registration Statement or supplement to the Time of Sale Prospectus or Prospectus or any Rule
462(b) Registration Statement unless the Company has furnished you a copy for your review prior to
filing and will not file any such proposed amendment or supplement to which you reasonably object.
Subject to the foregoing sentence, if the Registration Statement has become or becomes effective
pursuant to Rule 430A, or filing of the Prospectus is otherwise required under Rule 424(b), the
Company will cause the Prospectus, properly completed, and any supplement thereto to be filed in a
form approved by the Managers with the Commission pursuant to the applicable paragraph of Rule
424(b) within the time period prescribed and will provide evidence satisfactory to the Managers of
such timely filing. The Company will promptly advise the Managers (1) when the Registration
Statement, if not effective at the Execution Time, shall have become effective, (2) when the
Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission
pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with
the Commission, (3) when, prior to termination of the offering of the Shares, any amendment to the
Registration Statement shall have been filed or become effective, (4) of any request by the
Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b)
Registration Statement, or for any supplement to the Prospectus or for any additional information,
(5) of the issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the institution or threatening of any proceeding for that purpose and (6)
of the receipt by the Company of any notification with respect to the suspension of the
qualification of the Shares for sale in any jurisdiction or the

-13-

 

institution or threatening of any proceeding for such purpose. The Company will use its best
efforts to prevent the issuance of any such stop order or the suspension of any such qualification
and, if issued, to obtain as soon as possible the withdrawal thereof.

          (k) The Company will comply with all applicable securities and other applicable laws, rules
and regulations, including, without limitation, the Sarbanes Oxley Act, and use its best efforts to
cause the Company’s directors and officers, in their capacities as such, to comply with such laws,
rules and regulations, including, without limitation, the provisions of the Sarbanes Oxley Act.

          (l) As soon as practicable, the Company will make generally available to its security holders
and to the Managers an earnings statement or statements of the Company and its subsidiaries which
will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 under the
Securities Act.

          (m) The Company will use the net proceeds received by it from the sale of the Shares in the
manner specified in the Prospectus under “Use of Proceeds.”

          (n) The Company will comply with all applicable securities and other laws, rules and
regulations in each jurisdiction in which the Directed Shares are offered in connection with the
Directed Share Program.

          6. Covenants of the Underwriters. Each Underwriter severally covenants with the
Company not to take any action that would result in the Company being required to file with the
Commission under Rule 433(d) of the Securities Act a free writing prospectus or Company information
prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by
the Company thereunder, but for the action of the Underwriter.

          7. Conditions to the Obligations of the Underwriters. The obligations of the Company
to sell the Shares to the Underwriters and the several obligations of the Underwriters to purchase
and pay for the Shares shall be subject to the accuracy in all material respects of the
representations and warranties of the Company contained herein that are not qualified by
materiality and to the accuracy of the representations and warranties of the Company contained
herein that are qualified by materiality at the date hereof, the Closing Date, and any Option
Closing Date, if applicable, to the accuracy of the statements of the Company made in any
certificates pursuant to the provisions hereof, to the performance by the Company of their
respective obligations hereunder and to the following additional conditions:

          (a) The Company shall have requested and caused (i) Simpson Thacher & Bartlett LLP, counsel
for the Company, to furnish to the Underwriters their opinion and negative assurance statement,
each dated the Closing Date and, if applicable, any Option Closing Date, and addressed to the
Underwriters and substantially in the form of Exhibits B and C hereto; and (ii) Matthew J. Klaben,
Vice President, General Counsel and Secretary of the Company, to furnish to the Underwriters his
opinion dated the Closing Date and, if applicable, any Option Closing Date, addressed to the
Underwriters and substantially in the form of Exhibit D hereto.

-14-

 

          (b) The Underwriters shall have received from Shearman & Sterling LLP, counsel for the
Underwriters, such opinion or opinions, dated the Closing Date and, if applicable, any Option
Closing Date, and addressed to the Underwriters, with respect to the issuance and sale of the
Shares, the Time of Sale Prospectus, the Prospectus and Registration Statement and other related
matters as the Underwriters may reasonably require, and the Company shall have furnished to such
counsel such documents as they request for the purpose of enabling them to pass upon such matters.

          (c) The Company shall have furnished to the Underwriters a certificate of the Company, signed
by (x) the Chief Executive Officer or the President and (y) the principal financial or accounting
officer of the Company, dated the Closing Date and, if applicable, any Option Closing Date, to the
effect that the signers of such certificate have carefully examined the Time of Sale Prospectus,
the Prospectus and Registration Statement, any amendment or supplement to the Time of Sale
Prospectus, the Prospectus and Registration Statement and this Agreement and that:

     (i) the representations and warranties of the Company in this Agreement that
are not qualified by materiality are true and correct in all material respects, and
the representations and warranties of the Company in this Agreement that are
qualified by materiality are true and correct, in each case, on and as of the
Closing Date or any Option Closing Date, as the case may be, with the same effect as
if made on the Closing Date, or such Option Closing Date, as the case may be, and
the Company has complied with all the agreements and satisfied all the conditions on
its part to be performed or satisfied hereunder at or prior to the Closing Date, or
any Option Closing Date, as the case may be; and

     (ii) since the date of the most recent financial statements included in the
Time of Sale Prospectus and the Registration Statement (exclusive of any amendment
or supplement thereto), there has been no material adverse change in the condition,
financial or otherwise, or in the earnings, business, properties or results of
operations of the Company and its subsidiaries, taken as a whole, from that set
forth in the Time of Sale Prospectus and the Prospectus (exclusive of any amendments
or supplements thereto subsequent to the date of this Agreement).

          (d) At the date hereof and at the Closing Date, the Company shall have requested and caused
Ernst & Young LLP to furnish to the Underwriters a “comfort” letter, dated as of the date hereof,
and a bring-down “comfort” letter (i) on and dated as of the Closing Date and (ii) if applicable,
on and dated as of any Option Closing Date, each in form and substance satisfactory to the
Managers, confirming that it is an independent registered public accounting firm within the meaning
of the Exchange Act and the applicable published rules and regulations thereunder and confirming
certain matters with respect to the audited and unaudited financial statements and other financial
and accounting information contained in the Time of Sale Prospectus, the Prospectus and
Registration Statement; provided that the letter delivered on the Closing Date shall use a
“cut-off” date no more than three days prior to the date of such letter.

-15-

 

          All references in this Section 7(d) to the Time of Sale Prospectus, the Prospectus and
Registration Statement include any amendment or supplement thereto at the date of the applicable
letter.

          (e) The “lock-up” agreements, each substantially in the form of Exhibit A hereto, between you
and each executive officer and director of the Company and certain affiliates of First Reserve
Corporation, listed on Schedule IV hereto, relating to sales and certain other dispositions of
shares of Common Stock or certain other securities, delivered to you on or before the date hereof,
shall be in full force and effect on the Closing Date.

          (f) Subsequent to the execution and delivery of this Agreement and prior to the Closing Date
or, if applicable, any Option Closing Date:

     (i) there shall not have occurred any downgrading, nor shall any notice have
been given of any intended or potential downgrading or of any review for a possible
change that does not indicate the direction of the possible change, in the rating
accorded any of the Company’s securities by any “nationally recognized statistical
rating organization,” as such term is defined for purposes of Rule 436(g)(2) under
the Securities Act; and

     (ii) there shall not have occurred any change, or any development involving a
prospective change, in the condition, financial or otherwise, or in the earnings,
business, properties or results of operations of the Company and its subsidiaries,
taken as a whole, from that set forth in the Time of Sale Prospectus (exclusive of
any amendments or supplements thereto subsequent to the date of this Agreement)
that, in your judgment, is material and adverse and that makes it, in your judgment,
impracticable to market the Shares on the terms and in the manner contemplated in
the Time of Sale Prospectus.

          (g) Prior to the Closing Date, or, if applicable, any Option Closing Date, the Company shall
have furnished to the Underwriters such further information, certificates and documents as the
Underwriters may reasonably request.

          (h) The Shares shall have been listed, subject to notice of issuance, on the Nasdaq National
Market, and satisfactory evidence of such actions shall have been provided to the Managers.

          (i) On the Closing Date, and, if applicable, any Option Closing Date, the Registration
Statement shall be effective; no stop order suspending the effectiveness of the Registration
Statement shall be in effect, and no proceedings for such purpose shall be pending before or
threatened by the Commission.

          If any of the conditions specified in this Section 7 shall not have been fulfilled when and as
provided in this Agreement, or if any of the opinions, letters, evidence and certificates mentioned
above in this Section 7 shall not be reasonably satisfactory in form and

-16-

 

substance to the Managers and counsel for the Underwriters, this Agreement and all obligations
of the Underwriters hereunder may be cancelled at, or at any time prior to, the Closing Date or, if
applicable, any Option Closing Date (solely with respect to the obligations of the Underwriters to
purchase Additional Shares on such date) by the Underwriters. Notice of such cancellation shall be
given to the Company in writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 7 will be delivered at the office of
counsel for the Underwriters, at 599 Lexington Avenue, New York, New York 10022, on the Closing
Date.

          8. Reimbursement of Expenses. If the sale of the Shares provided for herein is not
consummated because any condition to the obligations of the Underwriters set forth in Section 7
hereof is not satisfied, because of any termination pursuant to Section 12 hereof or because of any
refusal, inability or failure on the part of any Company to perform any agreement herein or comply
with any provision hereof other than by reason of a default by any of the Underwriters, including
any default pursuant to Section 11 hereof, the Company will reimburse the Underwriters severally
through the Managers on demand for all reasonable expenses (including reasonable fees and
disbursements of counsel) that shall have been incurred by them in connection with the proposed
purchase and sale of the Shares.

          9. Indemnification and Contribution. (a) The Company agrees to indemnify and hold
harmless each Underwriter, the directors, officers and Affiliates of each Underwriter and each
person who controls any Underwriter within the meaning of either the Securities Act or the Exchange
Act against any and all losses, claims, damages or liabilities, joint or several, to which they or
any of them may become subject under the Securities Act, the Exchange Act or other U.S. federal or
state statutory law or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the Registration Statement,
any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as
defined in Rule 433(h) under the Securities Act, any Company information that the Company has
filed, or is required to file, pursuant to Rule 433(d) of the Securities Act (provided that the
Company’s indemnification obligation shall not extend to any free writing prospectus or Company
information required to be filed by the Company due to an Underwriter’s breach of Section 6) or the
Prospectus, or in any amendment or supplement thereto or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances under which they were
made, not misleading, and (subject to the limitations set forth in the proviso to this sentence)
agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by it in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company will not be liable
in any such case to the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or alleged omission
made in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any
issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company
information that the Company has filed, or is required to file, pursuant to Rule 433(d) of the
Securities Act, or

-17-

 

the Prospectus, or in any amendment or supplement thereto, in reliance upon and in conformity
with written information furnished to the Company by or on behalf of any Underwriter through the
Managers specifically for inclusion therein. This indemnity agreement will be in addition to any
liability that the Company may otherwise have. The Company shall not be liable under this Section
9 to any indemnified party regarding any settlement or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of
which indemnification or contribution may be sought hereunder (whether or not the indemnified
parties are actual or potential parties to such claim or action) unless such settlement, compromise
or consent is consented to by the Company, which consent shall not be unreasonably withheld.

          (b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the
Company, its directors, officers and Affiliates, and each person who controls the Company within
the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing
indemnity from the Company to each Underwriter, but only with reference to written information
relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through
the Managers specifically for inclusion in the Registration Statement, any preliminary prospectus,
the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus (or in any
amendment or supplement thereto). This indemnity agreement will be in addition to any liability
that any Underwriter may otherwise have. The Company acknowledges that, under the heading
“Underwriting,” the table after the first paragraph, the thirteenth paragraph, the fourteenth
paragraph and the fifteenth paragraph in any preliminary prospectus, the Time of Sale Prospectus
and the Prospectus constitute the only information furnished in writing by or on behalf of the
Underwriters for inclusion in the Registration Statement, any preliminary prospectus, the Time of
Sale Prospectus, any issuer free writing prospectus or the Prospectus or in any amendment or
supplement thereto.

          (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the
commencement of any action, such indemnified party will, if a claim in respect thereof is to be
made against the indemnifying party under this Section 9, notify the indemnifying party in writing
of the commencement thereof; but the failure so to notify the indemnifying party (i) will not
relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the indemnifying party
of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party
from any obligations to any indemnified party other than the indemnification obligation provided in
paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including
local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent
the indemnified party in any action for which indemnification is sought (in which case the
indemnifying party shall not thereafter be responsible for the fees and expenses of any separate
counsel, other than local counsel if not appointed by the indemnifying party, retained by the
indemnified party or parties except as set forth below); provided, however, that
such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party’s election to appoint counsel (including local counsel) to represent the
indemnified party in an action, the indemnified party shall have the right to employ separate
counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs

-18-

 

and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying
party to represent the indemnified party would present such counsel with a conflict of interest
(based on the advise of counsel to the indemnified person); (ii) such action includes both the
indemnified party and the indemnifying party and the indemnified party shall have reasonably
concluded (based on the advise of counsel to the indemnified person) that there may be legal
defenses available to it and/or other indemnified parties that are different from or additional to
those available to the indemnifying party; (iii) the indemnifying party shall not have employed
counsel reasonably satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action; or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying
party. It is understood and agreed that the indemnifying party shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm (in addition to any local counsel) for all indemnified
parties. Any such separate firm for any Underwriter, its directors, officers and Affiliates and
any control person shall be designated in writing by the Managers and any such separate firm for
any of the Company, its directors, officers and Affiliates and any control person shall be
designated in writing by the Company. An indemnifying party will not, without the prior written
consent of the indemnified parties, settle or compromise or consent to the entry of any judgment
with respect to any pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the indemnified parties are
actual or potential parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability arising out of such
claim, action, suit or proceeding and does not include any statement as to, or any admission of,
fault, culpability or failure to act by or on behalf of any indemnified party.

          (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 9 is
unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company
and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection with investigating
or defending any loss, claim, damage, liability or action) (collectively, “Losses”) to which the
Company and one or more of the Underwriters may be subject in such proportion as is appropriate to
reflect the relative benefits received by the Company on the one hand and by the Underwriters on
the other from the offering of the Shares; provided, however, that in no case shall
any Underwriter be responsible for any amount in excess of the purchase discount or commission
applicable to the Shares purchased by such Underwriter hereunder. If the allocation provided by
the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters
severally shall contribute in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Company on the one hand and the Underwriters on the
other in connection with the statements or omissions that resulted in such Losses, as well as any
other relevant equitable considerations. Benefits received by the Company shall be deemed to be
equal to the total net proceeds from the offering (before deducting expenses) received by them, and
benefits received by the Underwriters shall be deemed to be equal to the total purchase discounts
and commissions. Relative fault shall be determined by reference to, among other things, whether
any untrue or alleged untrue statement of a material fact or the omission or alleged

-19-

 

omission to state a material fact relates to information provided by the Company on the one
hand or the Underwriters on the other, the intent of the parties and their relative knowledge,
access to information and opportunity to correct or prevent such untrue statement or omission and
any other equitable considerations appropriate in the circumstance. The Company and the
Underwriters agree that it would not be just and equitable if the amount of such contribution were
determined by pro rata allocation or any other method of allocation that does not take account of
the equitable considerations referred to above. Notwithstanding the provisions of this paragraph
(d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section
9 are several in proportion to their respective obligations and not joint. For purposes of this
Section 9, each person who controls an Underwriter within the meaning of either the Securities Act
or the Exchange Act and each director, officer, employee, Affiliate and agent of an Underwriter
shall have the same rights to contribution as such Underwriter, and each person who controls the
Company within the meaning of either the Securities Act or the Exchange Act and each officer and
director of the Company shall have the same rights to contribution as the Company, subject in each
case to the applicable terms and conditions of this paragraph (d).

          10. Directed Share Program Indemnification. (a) The Company agrees to indemnify and
hold harmless Morgan Stanley, each person, if any, who controls Morgan Stanley within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of
Morgan Stanley within the meaning of Rule 405 of the Securities Act (“Morgan Stanley Entities”)
from and against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) (i) caused by any untrue statement or alleged untrue
statement of a material fact contained in any material prepared by or with the consent of the
Company for distribution to Participants in connection with the Directed Share Program or caused by
any omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; (ii) caused by the failure of any
Participant to pay for and accept delivery of Directed Shares that the Participant agreed to
purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program,
other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally
judicially determined to have resulted from the bad faith or gross negligence of Morgan Stanley
Entities.

     (b) In case any proceeding (including any governmental investigation) shall be instituted
involving any Morgan Stanley Entity in respect of which indemnity may be sought pursuant to Section
10(a), the Morgan Stanley Entity seeking indemnity, shall promptly notify the Company in writing
and the Company, upon request of the Morgan Stanley Entity, shall retain counsel reasonably
satisfactory to the Morgan Stanley Entity to represent the Morgan Stanley Entity and any others the
Company may designate in such proceeding and shall pay the fees and disbursements of such counsel
related to such proceeding. In any such proceeding, any Morgan Stanley Entity shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of
such Morgan Stanley Entity unless (i) the Company shall have agreed to the retention of such
counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include
both the Company and the Morgan Stanley Entity and

-20-

 

representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. The Company shall not, in respect of the legal
expenses of the Morgan Stanley Entities in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in
addition to any local counsel) for all Morgan Stanley Entities. Any such separate firm for the
Morgan Stanley Entities shall be designated in writing by Morgan Stanley. The Company shall not be
liable for any settlement of any proceeding effected without its written consent, but if settled
with such consent or if there be a final judgment for the plaintiff, the Company agrees to
indemnify the Morgan Stanley Entities from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time a Morgan Stanley
Entity shall have requested the Company to reimburse it for fees and expenses of counsel as
contemplated by the second and third sentences of this paragraph, the Company agrees that it shall
be liable for any settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 30 days after receipt by the Company of the aforesaid request
and (ii) the Company shall not have reimbursed the Morgan Stanley Entity in accordance with such
request prior to the date of such settlement. The Company shall not, without the prior written
consent of Morgan Stanley, effect any settlement of any pending or threatened proceeding in respect
of which any Morgan Stanley Entity is or could have been a party and indemnity could have been
sought hereunder by such Morgan Stanley Entity, unless such settlement includes an unconditional
release of the Morgan Stanley Entities from all liability on claims that are the subject matter of
such proceeding.

     (c) To the extent the indemnification provided for in Section 10(a) is unavailable to a Morgan
Stanley Entity or insufficient in respect of any losses, claims, damages or liabilities referred to
therein, then the Company in lieu of indemnifying the Morgan Stanley Entity thereunder, shall
contribute to the amount paid or payable by the Morgan Stanley Entity as a result of such losses,
claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Morgan Stanley Entities on the other hand
from the offering of the Directed Shares or (ii) if the allocation provided by clause 10(c)(i)
above is not permitted by applicable law, in such proportion as is appropriate to reflect not only
the relative benefits referred to in clause 10(c)(i) above but also the relative fault of the
Company on the one hand and of the Morgan Stanley Entities on the other hand in connection with any
statements or omissions that resulted in such losses, claims, damages or liabilities, as well as
any other relevant equitable considerations. The relative benefits received by the Company on the
one hand and the Morgan Stanley Entities on the other hand in connection with the offering of the
Directed Shares shall be deemed to be in the same respective proportions as the net proceeds from
the offering of the Directed Shares (before deducting expenses) and the total underwriting
discounts and commissions received by the Morgan Stanley Entities for the Directed Shares, bear to
the aggregate Public Offering Price of the Directed Shares. If the loss, claim, damage or
liability is caused by an untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact, the relative fault of the Company on the one hand and
the Morgan Stanley Entities on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement or the omission or alleged omission relates
to information supplied by the Company or by the Morgan Stanley Entities and

-21-

 

the parties’ relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

     (d) The Company and the Morgan Stanley Entities agree that it would not be just or equitable
if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the
Morgan Stanley Entities were treated as one entity for such purpose) or by any other method of
allocation that does not take account of the equitable considerations referred to in Section 10(c).
The amount paid or payable by the Morgan Stanley Entities as a result of the losses, claims,
damages and liabilities referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses reasonably
incurred by the Morgan Stanley Entities in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 10, no Morgan Stanley Entity shall
be required to contribute any amount in excess of the amount by which the total price at which the
Directed Shares distributed to the public were offered to the public exceeds the amount of any
damages that such Morgan Stanley Entity has otherwise been required to pay. The remedies provided
for in this Section 10 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified party at law or in equity.

     (e) The indemnity and contribution provisions contained in this Section 10 shall remain
operative and in full force and effect regardless of (i) any termination of this Agreement, (ii)
any investigation made by or on behalf of any Morgan Stanley Entity or the Company, its officers or
directors or any person controlling the Company and (iii) acceptance of and payment for any of the
Directed Shares.

          11. Default by an Underwriter. If any one or more Underwriters shall fail to purchase
and pay for any of the Shares agreed to be purchased by such Underwriter or Underwriters hereunder
and such failure to purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of Shares set forth
opposite their names in Schedule I hereto bears to the aggregate principal amount of Shares set
forth opposite the names of all the remaining Underwriters) the Shares which the defaulting
Underwriter or Underwriters agreed but failed to purchase; provided, however, that
in the event that the aggregate principal amount of Shares which the defaulting Underwriter or
Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of
Shares set forth in Schedule I hereto, the Company shall be entitled to a further period of 36
hours within which to procure another party or parties reasonably satisfactory to the nondefaulting
Underwriter or Underwriters to purchase no less than the amount of such unpurchased Shares that
exceeds 10% of the principal amount thereof upon such terms herein set forth. If, however, the
Company shall not have completed such arrangements within 72 hours after such default and the
principal amount of such unpurchased Shares exceeds 10% of the principal amount of such Shares to
be purchased on such date, then this Agreement will terminate without liability to any
nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set
forth in this Section 11, the Closing Date shall be postponed for such period, not exceeding five
Business Days, as the Underwriters, the Company and its counsel shall determine in order that the
required changes in the Time of Sale Prospectus, the Prospectus or in any other documents or

-22-

 

arrangements may be effected. Nothing contained in this Agreement shall relieve any
defaulting Underwriter of its liability, if any, to the Company or any nondefaulting Underwriter
for damages occasioned by its default hereunder.

          12. Termination. This Agreement shall be subject to termination in the absolute
discretion and in the sole judgment of the Managers, by notice given to the Company prior to
delivery of and payment for the Shares, if at any time prior to such time (i) trading generally
shall have been suspended or materially limited on, or by, as the case may be, any of the New York
Stock Exchange or the Nasdaq National Market, (ii) trading of any securities of the Company shall
have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption
in securities settlement, payment or clearance services in the United States shall have occurred,
(iv) any moratorium on commercial banking activities shall have been declared by Federal or New
York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities,
or any change in financial markets or any calamity or crisis that, in your sole judgment, is
material and adverse and which, singly or together with any other event specified in this clause
(v), makes it, in your sole judgment, impracticable or inadvisable to proceed with the offer, sale
or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale
Prospectus or the Prospectus (exclusive of any amendment or supplement thereto).

          13. Entire Agreement. (a) This Agreement, together with any contemporaneous written
agreements and any prior written agreements (to the extent not superseded by this Agreement) that
relate to the offering of the Shares, represents the entire agreement among the Company and the
Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale
Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

          (b) The Company acknowledges that in connection with the offering of the Shares: (i) the
Underwriters have acted at arm’s length from, are not agents of, and owe no fiduciary duties to,
the Company or any other person, (ii) the Underwriters owe the Company only those duties and
obligations set forth in this Agreement and prior or contemporaneous written agreements (to the
extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests
that differ from those of the Company. The Company agrees that it will not claim that the
Underwriters, or any of them, has rendered advisory services of any nature or respect, or owed or
owes a fiduciary or similar duty to the Company, in connection with such transaction or the process
leading thereto.

          14. Representations and Indemnities to Survive. The respective agreements,
representations, warranties, indemnities and other statements of the Company or its officers and of
the Underwriters set forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of the Underwriters or the Company or
any of the indemnified persons referred to in Sections 9 and 10 hereof, and will survive delivery
of and payment for the Shares. The provisions of Sections 8, 9 and 10 hereof shall survive the
termination or cancellation of this Agreement.

parties hereto and their respective successors and the indemnified persons referred to in Sections
9 and 10 hereof and their respective successors, and no other person will have any right or
obligation hereunder. No purchaser of Shares from any Underwriters shall be deemed to be a
successor merely by reason of such purchase.

          17. Applicable Law. This Agreement will be governed by and construed in accordance
with the laws of the State of New York applicable to contracts made and to be performed within the
State of New York. The parties hereto each hereby waive any right to trial by jury in any action,

DILUTION

     If you invest in our common stock, your interest will be diluted to the extent of
the difference between the initial public offering price per share and the net tangible book value
per share after this offering. The net tangible book value per share presented below is equal to
the amount of our total tangible assets (total assets less intangible assets) less total
liabilities as of March 31, 2006, divided by the number of shares of our common stock that would
have been held by our existing stockholders had the stock dividend of 1,875,000 additional shares
to our existing stockholders shortly after the expiration of the underwriters’ over-allotment
option, assuming no exercise of that option, been made as of March 31, 2006. As of March 31, 2006,
prior to giving effect to the offering, we had a net tangible book deficit of $(263.2) million, or
$(33.09) per share. On a pro forma basis, after giving effect to:

	 	•	 	the sale of shares of common stock in this offering at an assumed initial public
offering price of $20.00 per share, the mid-point of the price range on the cover of this
prospectus;
	 
	 	•	 	the payment of the $208.8 million dividend that we intend to declare prior to the
consummation of the offering to the existing stockholders;
	 
	 	•	 	the application of the estimated net proceeds as described under “Use of Proceeds” as
well as the $25.0 million voluntary principal prepayment under the term loan portion of our
senior secured credit facility in the second quarter of 2006 and the payment of $16.5
million of cash to acquire Cooler Service;
	 
	 	•	 	the 4.6263-for-one stock split we effected prior to the consummation of this offering;
	 
	 	•	 	the issuance of 2,651,012 shares which have been issued to FR X Chart Holdings LLC upon
its exercise of its warrant for $37.1 million in cash;
	 
	 	•	 	the issuance of 609,856 shares which have been issued to certain members of management
upon their exercise of their rollover options for $2.1 million in cash; and
	 
	 	•	 	the effect of any other pro forma adjustments,

our pro forma net tangible book deficit as of March 31, 2006 would have been $(201.3) million, or
$(7.87) per share of common stock. This represents an immediate increase in net tangible book value
(or a decrease in net tangible book deficit) of $25.22 per share to existing stockholders and an
immediate dilution in net tangible book value of $27.87 per share to new investors.

     The following table illustrates this dilution on a per share basis:

	 	 	 	 	 	 	 	 	 
	Initial public offering price per share
	 	 	 	 	 	$	20.00	 
	Net tangible book deficit per share at March 31, 2006
	 	$	(33.09	)	 	 	 	 
	Increase in net tangible book value per share
attributable to new investors and the transactions
described above
	 	$	25.22	 	 	 	 	 
	 
	 	 	 	 	 	 	 
	Pro forma net tangible book deficit per share after the offering
	 	 	 	 	 	$	(7.87	)
	 
	 	 	 	 	 	 	 
	Dilution per share to new investors
	 	 	 	 	 	$	27.87	 
	 
	 	 	 	 	 	 	 

  A $0.25 increase (decrease) in the initial public offering price from the assumed initial
public offering price of $20.00 per share would result in no change to our pro forma net tangible
book deficit, because the cash dividend paid to the existing stockholders would increase or
decrease equally, and would increase (decrease) the dilution in net tangible book value per share
to new investors in this offering by $0.25 per share, assuming no other change to the number of
shares offered by us as set forth on the cover page of this prospectus. We will reduce the number
of shares that we will issue to our existing stockholders in the stock dividend described in the
first paragraph above by the number of shares sold to the underwriters pursuant to their
over-allotment option. We will also pay to our existing stockholders a cash dividend equal to all
proceeds we receive from any such sale to the underwriters. As a result, our pro forma net tangible
book value will not be affected by the underwriters’ exercise of their over-
allotment option.

Dear Sirs and Mesdames:

          The undersigned understands that Morgan Stanley & Co. Incorporated (“Morgan Stanley”), Lehman
Brothers Inc. (“Lehman”) and UBS Securities LLC (“UBS,” together with Morgan Stanley and Lehman,
the “Managers”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with
Chart Industries, Inc., a Delaware corporation (the “Company”), providing for the public offering
(the “Public Offering”) by the several underwriters named in Schedule I to the Underwriting
Agreement (the “Underwriters”), of                     shares (the “Shares”) of the Common Stock, par value
$0.01 of the Company (the “Common Stock”).

          To induce the Underwriters that may participate in the Public Offering to continue their
efforts in connection with the Public Offering, the undersigned hereby agrees that, without the
prior written consent of the Managers on behalf of the Underwriters, it will not, during the period
commencing on the date hereof and ending 180 days after the date of the final prospectus relating
to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares
of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock
or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any
of the economic consequences of ownership of Common Stock, whether any such transaction described
in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities,
in cash or otherwise. The foregoing sentence shall not apply to transactions relating to (A)
shares of Common Stock or other securities acquired in open market transactions after the
completion of the offering of the Shares; provided that no filing by any party under the
Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of
Common Stock or other securities acquired in such open market transactions, (B) transfers of shares
of Common Stock or any security convertible, exchangeable for or

A-1

 

exercisable into Common Stock as a bona fide gift or gifts as a result of the operation of law
or testate or intestate succession, (C) transfers by the undersigned to a trust, partnership,
limited liability company or other entity, all of the beneficial interests of which are held,
directly or indirectly, by the undersigned or his or her spouse or children, or (D) distributions
of shares of Common Stock or any security convertible, exchangeable for or exercisable into Common
Stock to limited partners or stockholders of the undersigned; provided that in the case of
any transfer or distribution pursuant to clause (B), (C) or (D), (i) each donee or distributee
shall sign and deliver a lock-up letter substantially in the form of this letter and (ii)
the undersigned and recipient shall not be required to, and shall not voluntarily, file a report
under the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock
during the restricted period referred to in the foregoing sentence. In addition, the undersigned
agrees that, without the prior written consent of the Managers on behalf of the Underwriters, it
will not, during the period commencing on the date hereof and ending 180 days after the date of the
Prospectus, make any demand for or exercise any right with respect to, the registration of any
shares of Common Stock or any security convertible into or exercisable or exchangeable for Common
Stock, unless the Managers have waived the lock-up restrictions imposed on the Company in
connection with the Public Offering. The undersigned also agrees and consents to the entry of stop
transfer instructions with the Company’s transfer agent and registrar against the transfer of the
undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

     It is understood that, if the Company notifies the undersigned in writing that it does not
intend to proceed with the Public Offering, if the Underwriting Agreement does not become effective
on or before September 30, 2006, or if the Underwriting Agreement (other than the provisions
thereof that survive termination) shall terminate or be terminated prior to payment for and
delivery of the Shares, the undersigned will be released from the obligations under this agreement.

     The undersigned understands that the Company and the Underwriters are relying upon this
agreement in proceeding toward consummation of the Public Offering. The undersigned further
understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs,
legal representatives, successors and assigns.

     Whether or not the Public Offering actually occurs depends on a number of factors, including

c/o Morgan Stanley & Co. Incorporated

1585 Broadway

New York, New York 10036

Ladies and Gentlemen:

          We have acted as counsel to Chart Industries, Inc., a Delaware corporation (the “Company”), in
connection with the purchase by you of an aggregate of 12,500,000 shares (the “Shares”) of Common
Stock, par value $0.01 per share (the “Common Stock”), of the Company from the Company pursuant to
the Underwriting Agreement, dated [                    ], 2006, between you and the Company (the “Underwriting
Agreement”).

          We have examined the Registration Statement on Form S-1 (File No. 333-133254) (the
“Registration Statement”) filed by the Company under the Securities Act of 1933, as amended (the
“Securities Act”), as it became effective under the Securities Act; the Company’s prospectus, dated
[                    ], 2006 (the “Prospectus”), filed by the Company pursuant to Rule 424(b) of the rules and
regulations of the Securities and Exchange Commission under the Securities Act; the Company’s
preliminary prospectus, dated [                    ], 2006 (the “Preliminary Prospectus”),

included in the Registration Statement immediately prior to the time the Registration
Statement became effective under the Securities Act; and the Underwriting Agreement. We also have
examined a specimen certificate representing the Common Stock of the Company. In addition, we have
examined, and have relied as to matters of fact upon, the documents delivered to you at the closing
and upon originals, or duplicates or certified or conformed copies, of such corporate and other
records, agreements, documents and other instruments and such certificates or comparable documents
of public officials and of officers and representatives of the Company, and have made such other
investigations, as we have deemed relevant and necessary in connection with the opinions
hereinafter set forth.

          In such examination, we have assumed the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as duplicates or certified or conformed copies
and the authenticity of the originals of such latter documents.

          Based upon the foregoing, and subject to the qualifications, assumptions and limitations
stated herein, we are of the opinion that:

     1 The Company has been duly incorporated and is validly existing and in good standing
as a corporation under the law of the State of Delaware and has full corporate power and
authority to conduct its business as described in the Registration Statement, the
Preliminary Prospectus and the Prospectus.

     2 The Shares have been duly authorized by the Company and, upon payment and delivery in
accordance with the Underwriting Agreement, the Shares will be, validly issued, fully paid
and nonassessable.

     3. The statements made in the Preliminary Prospectus and the Prospectus under
the caption “Description of Capital Stock”, insofar as they purport to constitute
summaries of the terms of the Common Stock (including the

B-2

 

			
	 	 	 
	Morgan Stanley & Co. Incorporated	 	 
	Lehman Brothers Inc.	 	 
	UBS Securities LLC, Et. Al.
	 	[                    ], 2006
	 	 	 

Shares), constitute accurate summaries of the terms of such Common Stock in
all material respects.

     4. The statements made in the Preliminary Prospectus and the Prospectus under
the caption “Material United States Federal Income and Estate Tax Consequences to
Non-U.S. Holders,” insofar as they purport to constitute summaries of matters of
United States federal tax law and regulations or legal conclusions with respect
thereto, constitute accurate summaries of the matters described therein in all
material respects.

     5. The Underwriting Agreement has been duly authorized, executed and delivered
by the Company.

     6. The issue and sale of the Shares by the Company and the execution, delivery
and performance by the Company of the Underwriting Agreement will not breach or
result in a default under any indenture, mortgage, deed of trust, loan agreement or
other agreement or instrument filed as an exhibit to the Registration Statement,
nor will such action violate the Amended and Restated Certificate of Incorporation
or Amended and Restated By-laws of the Company or any federal or New York statute
or the Delaware General Corporation Law or any rule or regulation that has been
issued pursuant to any federal or New York statute or the Delaware General
Corporation Law or any order known to us issued pursuant to any federal or New York
statute or the Delaware General Corporation Law by any court or governmental agency
or body having jurisdiction over the Company or any of its subsidiaries or any of
their properties.

     7. No consent, approval, authorization, order, registration or qualification
of or with any federal or New York governmental agency or body or any Delaware
governmental agency or body acting pursuant to the Delaware General Corporation Law
or, to our knowledge, any federal or New York court or any Delaware court acting
pursuant to the Delaware General Corporation Law is required for the issue and sale
of the Shares by the Company and the compliance by the Company with all of the
provisions of the Underwriting Agreement, except for the registration under the
Securities Act and the Securities Exchange Act of 1934, as amended, of the Shares,
and such consents, approvals, authorizations, registrations or qualifications as
may be required under state securities or Blue Sky laws in connection with the
purchase and distribution of the Shares by the Underwriters.

     8. The Registration Statement has become effective under the Securities Act
and the Prospectus was filed on [                    ], 2006 pursuant to Rule 424(b) of the rules
and regulations of the Commission under the Securities Act

	UBS Securities LLC, Et. Al.
	 	[                    ], 2006
	 	 	 

and, to our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued or proceeding for that purpose has been
instituted or threatened by the Commission.

     9. There are no preemptive rights under federal or New York law or under the
Delaware General Corporation Law to subscribe for or purchase shares of the Common
Stock. Except as disclosed in the Preliminary Prospectus and the Prospectus, there
are no preemptive or other rights to subscribe for or purchase, nor any restriction
upon the voting or transfer of, any shares of the Common Stock pursuant to the
Company’s Amended and Restated Certificate of Incorporation or Amended and Restated
By-laws or any agreement or other instrument filed as an exhibit to the
Registration Statement.

     10. The Company is not, after giving effect to the offering and sale of Shares
and the application of proceeds thereof as described in the Prospectus will not be,
an “investment company” within the meaning of and subject to regulation under the
Investment Company Act of 1940, as amended.

          We do not express any opinion herein concerning any law other than the law of the State of New
York, the federal law of the United States and the Delaware General Corporation Law.

          This opinion letter is rendered to you in connection with the above-described transaction.
This opinion letter may not be relied upon by you for any other purpose, or relied upon by, or
furnished to, any other person, firm or corporation without our prior written consent, except that

     In connection with, and under the circumstances applicable to, the offering of the Shares, we
participated in conferences with certain officers and employees of the Company, representatives of

Re: Chart Industries, Inc.

Ladies and Gentlemen:

          I am the Vice President, General Counsel and Secretary of Chart Industries, Inc., a Delaware
corporation (the “Company”), and have acted as counsel for the Company and those direct and
indirect subsidiaries of the Company listed on Annex I attached hereto (collectively, the
“Significant Subsidiaries”) in connection with the purchase by you of an aggregate of
12,500,000 shares (the “Shares”) of the Company’s Common Stock, par value $0.01 per share
(the “Common Stock”), from the Company pursuant to the Underwriting Agreement, dated
[                    ], 2006, between you and the Company (the “Underwriting Agreement”). Unless
otherwise defined herein, terms defined in the Underwriting Agreement are used herein with the same
meaning.

          This opinion is delivered to you pursuant to Section 7(a)(ii) of the Underwriting Agreement.
Concurrent with the delivery of this opinion Simpson Thacher & Bartlett LLP, special counsel to the
Company is delivering to you separate opinions to which you are referred for further information
regarding legal matters arising under the Underwriting Agreement.

          In arriving at the opinions express below, I or the attorneys, paralegals and other
professionals under my supervision or direction (with whom I have consulted) have examined and
relied on the following documents:

     (i) an executed copy of the Underwriting Agreement;

     (ii) copies of each of (i) the respective certificates of incorporation or similar
organizational documents of the Company and the Significant Subsidiaries (other than Chart
Biomedical Limited and Chart Ferox a.s. (collectively, the “Foreign 

D-1

 

Subsidiaries”)), each as amended to the date of this letter and certified by
the Secretary of State of Delaware and (ii) the respective bylaws or similar organizational
documents of the Company and the Significant Subsidiaries (other than the Foreign
Subsidiaries), each as amended to the date of this letter and certified by an officer of the
Company to be true and correct on the date of this letter (together, the “Organizational
Documents”);

     (iii) the Registration Statement on Form S-1 (File No. 333-133254) (the
“Registration Statement”) filed by the Company under the Securities Act of 1933, as
amended (the “Securities Act”), as it became effective under the Securities Act;

     (iv) the Company’s preliminary prospectus, dated [___], 2006 (the “Preliminary
Prospectus”), included in the Registration Statement immediately prior to the time the
Registration Statement became effective under the Securities Act;

     (v) the Company’s prospectus, dated [___], 2006 (the “Prospectus”), filed by
the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and
Exchange Commission under the Securities Act;

     (vi) the free writing prospectus and pricing information included on Schedule A hereto
(such scheduled free writing prospectus and pricing information, together with the
Preliminary Prospectus, the “Pricing Disclosure Package”); and

     (vii) such other documents as I or the attorneys, paralegals and other professionals
under my supervision or direction (with whom I have consulted) have deemed necessary or
appropriate as a basis for the opinions set forth below.

          In addition, I or the attorneys, paralegals or other professionals under my supervision or
direction (with whom I have consulted) have examined and relied upon the originals, or duplicates
or certified or conformed copies, of all such corporate records, agreements, documents and other
instruments and such certificates or comparable documents of public officials and of officers and
representatives of the Company and its subsidiaries and have made such other investigations of fact
and law, as I have deemed relevant and necessary in connection with the opinions hereinafter set
forth.

          In such examination, I have assumed the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of all documents submitted to me as originals, the conformity to
original documents of all documents submitted to me as duplicates or certified or conformed or
translated copies and the authenticity of the originals of such latter documents.

          My opinion set forth in paragraph 6 below with respect to the ownership of the outstanding
shares of capital stock of the Significant Subsidiaries is based solely upon my review of the stock
ledgers of the Significant Subsidiaries or such comparable documents of the Foreign Subsidiaries
certified to me by representatives of the Foreign Subsidiaries. The identification of the
outstanding shares of the Company’s Common Stock, for purposes of my opinion in paragraph 5 below,
is based solely upon my review of the stock ledgers of the Company.

D-2

 

          Based upon the foregoing and subject to the qualifications and limitations stated herein, I am
of the opinion that:

     1. The Company has the power and authority to own or lease, as the case may be, and to
operate its properties and conduct its business as described in the Registration Statement,
the Preliminary Prospectus and the Prospectus.

     2. The Company has the corporate power and authority to execute, deliver and perform
the Underwriting Agreement and has taken all corporate action necessary to authorize the
execution, delivery and performance of the Underwriting Agreement.

     3. The Company is duly qualified to do business as a foreign corporation and is in good
standing under the laws of each jurisdiction which requires such qualification, except to
the extent that the failure to be so qualified or in good standing would not reasonably be
expected to have a Material Adverse Effect.

     4. Each Significant Subsidiary (other than the Foreign Subsidiaries, as to which I
express no opinion) has been duly incorporated, is validly existing as a corporation in good
standing under the laws of the State of Delaware, has the corporate power and authority to
own or lease its property and to conduct its business as described in the Registration
Statement, the Preliminary Prospectus and the Prospectus and is duly qualified to transact
business and is in good standing in each jurisdiction which requires such qualification,
except to the extent that the failure to be so qualified or be in good standing would not
reasonably be expected to have a Material Adverse Effect.

     5. All shares of the Company’s Common Stock outstanding prior to the issuance of the
Shares have been duly authorized and validly issued and are fully paid and non-assessable.

     6. All the outstanding shares of capital stock of each Significant Subsidiary (other
than the Foreign Subsidiaries, as to which I express no opinion) have been duly authorized,
validly issued and are fully paid and non-assessable, and all the outstanding shares of
capital stock of each Significant Subsidiary other than Chart Ferox a.s., and approximately
95.7% of the outstanding shares of capital stock of Chart Ferox a.s. are owned by the
Company either directly or through wholly owned subsidiaries, and such ownership is, to my
knowledge, free and clear of any security interest, claim, lien or encumbrance (other than
liens, encumbrances and restrictions imposed in favor of the lenders under the Company’s
senior secured credit facility described in the Preliminary Prospectus and the Prospectus or
permitted thereunder).

     7. The Company’s authorized equity capitalization is as set forth in the Preliminary
Prospectus and the Prospectus.

     8. To my knowledge, there are no pending or threatened actions, suits or proceedings by
or before any court or governmental agency, authority or body or any

D-3

 

arbitrator to which the
Company or any of its subsidiaries is a party or to which any of the properties of the
Company or any of its subsidiaries is subject that are required to be described in the
Registration Statement, the Preliminary Prospectus or the Prospectus and are not so
described.

     9. None of the execution and delivery of the Underwriting Agreement or the offering and
sale of the Shares will, as of the date of this letter and after giving effect to the
offering and sale of the Shares and the application of the proceeds thereof as described in
the Preliminary Prospectus and the Prospectus, conflict with, or result in a breach or
violation or imposition of any lien, charge or encumbrance upon any property or assets of
the Company or any of its subsidiaries pursuant to, (i) the Organizational Documents of the
Company, (ii) any Applicable Contract, or (iii) any Applicable Law, other than in the case
of clauses (ii) and (iii), such conflicts, breaches, violations, liens, charges or
encumbrances that would not reasonably be expected to have a Material Adverse Effect, and
provided that I express no opinion, in the case of clause (ii), with respect to financial
ratios or tests or any aspect of the financial condition or results of operations of the
Company to the extent the determination of such breach or violation requires quantitative
determination.

     10. The use of facsimile signatures, affixed in the name and on behalf of National City
Bank, as transfer agent and registrar, as applicable, on stock certificates evidencing
shares of the Company’s Common Stock (i) is permitted under the General Corporation Law of
the State of Delaware (the “DGCL”); (ii) will be valid and effective under DGCL; and
(iii) is not inconsistent with any provision of the Company’s Amended and Restated
Certificate of Incorporation or Amended and Restated Bylaws, as amended to date.

          As used in this letter, (i) “Applicable Laws” means those laws, rules or regulations
of the United States of America and the State of Ohio, which a lawyer in the State of Ohio
exercising customary professional diligence would reasonably be expected to recognize as being
applicable to transactions of the type contemplated by the Underwriting Agreement, but excluding
any securities laws of any jurisdiction and the rules and regulations of the National Association
of Securities Dealers, Inc. and (ii) “Applicable Contract” means any agreement or
instrument to which the Company or any of its subsidiaries is a party which are filed as an exhibit
to the Registration Statement pursuant to Item 601(b) (4) or (10) of Regulation S-K.

          I have not independently verified or checked the accuracy, completeness or fairness of the
statements made or included in the Registration Statement, the Preliminary Prospectus, the Pricing
Disclosure Package and the Prospectus and I take no responsibility therefor.

          In connection with, and under the circumstances applicable to the offering and sale of the
Shares, I or attorneys, paralegals and other professionals under my supervision or direction (with
whom I have consulted) have participated in conference calls and meetings with

D-4

 

certain officers and
employees of the Company and its subsidiaries, representatives of Ernst & Young LLP, outside
counsel to the Company and its subsidiaries and your counsel in the course of the preparation by
the Company of the Registration Statement, the Pricing Disclosure Package and the Prospectus. I or
attorneys, paralegals and other professionals under my supervision or direction (with whom I have
consulted) also have reviewed certain records and documents of the Company and its subsidiaries
furnished to me, as well as the documents delivered to you at the closing. Certain of such records
and documents were not in English or were governed by the laws of jurisdictions other than the
United States and, accordingly, I necessarily relied upon
directors, officers and employees of the Company and its subsidiaries and other persons in
evaluating such records and documents. Based upon our review of the Registration Statement, the
Pricing Disclosure Package and the Prospectus, our participation in the conference calls and
meetings referred to above and our review of the records and documents as described above, no facts
have come to my attention that cause me to believe that (i) the Registration Statement, at the time
it became effective, contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements therein not
misleading, (ii) the Pricing Disclosure Package, as of [___] p.m. on [                    ], 2006, contained any
untrue statement of a material fact or omitted to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were made not misleading
or (iii) the Prospectus, as of its date or as of the date of this letter, contained or contains any
untrue statement of a material fact or omitted to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were made, not
misleading, except that I express no view or belief in any of clauses (i), (ii) or (iii) above with
respect to the financial statements, schedules or other financial or statistical data, including
any pro forma financial information, contained in or omitted from the Registration Statement, the
Pricing Disclosure Package and the Prospectus.

          I am admitted to practice law in the State of Ohio, and do not express any opinion herein
concerning any law other than the laws of the United States of America, the State of Ohio and the
DGCL. To the extent that any of my opinions set forth above are governed by the laws of any
jurisdiction other than the State of Ohio, the DGCL or applicable federal law, I have assumed the
laws of all such jurisdictions which may govern the Underwriting Agreement or otherwise are
identical in all respects to the laws of the State of Ohio.

          This letter is rendered only to the addressees hereof and is solely for their benefit in
connection with the above-described transaction. This letter may not be relied upon, used,
circulated, quoted or otherwise referred to by you for any other purpose, or relied upon by, or
furnished to, any other person, firm or corporation without my prior written consent, except that
National City Bank, as transfer agent and registrar of the Company, may rely upon the opinions set
forth in paragraphs 5 and 10 above, subject to the assumptions, qualifications and limitations set
forth herein relating to such opinions.

Very truly yours,

CHART INDUSTRIES, INC.

STOCKHOLDER AGREEMENT

     This Stockholder Agreement (this “Agreement”) is made and entered into effective as of
July 25, 2006, by and between Chart Industries, Inc., a Delaware corporation (the
“Company”) and FR X Chart Holdings, LLC, a Delaware limited liability company (“First
Reserve”).

R E C I T A L S

     WHEREAS, First Reserve desires to set forth certain understandings with respect to its
holdings of shares of the Company’s common stock, par value $0.01 per share (the “Common
Stock”), as set forth herein.

     NOW, THEREFORE, in consideration of the foregoing recital, the mutual promises hereinafter set
forth, and other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

1. MANAGEMENT RIGHTS.

     1.1. Designation of Directors. (a) First Reserve shall be
entitled to designate individuals to serve on the Board of Directors of the Company (the
“Board”) in accordance with the following:

     (i) First Reserve shall be entitled to designate three (3)
directors for so long as it owns less than 50% but at least 25% of the aggregate
number of shares of Common Stock outstanding;

     (ii) First Reserve shall be entitled to designate two (2) directors
for so long as it owns less than 25% but more than 10% of the aggregate number of
shares of Common Stock outstanding; and

     (iii) First Reserve shall be entitled to designate one (1) director
for so long as it owns 10% of the aggregate number of shares of Common Stock
outstanding; and

     (iv) First Reserve shall not be entitled to designate any directors if it holds
less than 10% of the aggregate number of shares of Common Stock outstanding.

          (b) If any of the directors designated by First Reserve pursuant to Section 1.1(a)
hereof is removed or vacates such position for any reason whatsoever, First Reserve shall be
entitled to designate a new director to replace such former director as promptly as practicable
after the occurrence of such removal or vacancy.

          (c) In connection with an initial public offering or as otherwise required by
applicable federal and state securities laws, the Board shall be expanded to include such
additional independent directors as may be required by law or the rules of any exchange on which
the shares are traded, with such independent directors to be selected by the Board and to be
reasonably acceptable to First Reserve.

 

 

     1.2 Fiduciary Duties. For purposes of clarification, each of the parties hereto
agrees that, without limiting the fiduciary duties of members of the Board appointed by First
Reserve to act in the best
interests of the Company, First Reserve shall have no implied or express duty to the Company
or to any other stockholder or optionholder of the Company as a result of this Agreement, and may
act in its role as a stockholder accordingly. Each of the parties hereto further acknowledges that
the scope of the duty of loyalty imposed under the Delaware General Corporation Law on First
Reserve and its designees shall be defined and limited as follows.

          (a) Certain Potential Conflicts. Each of the parties hereto acknowledges that:

               (i) Any FRC Affiliate (as defined below) may engage in material business transactions with the
Company;

               (ii) directors, officers, and/or employees of any FRC Affiliate may serve as directors,
officers, and/or employees of the Company or its subsidiaries;

               (iii) one or more FRC Affiliates may now or in the future engage in the same or similar lines
of business or other business activities as those in which the Company or its subsidiaries may
engage; and

               (iv) one or more FRC Affiliates may exercise a controlling influence over certain of the
business, policy and strategic decisions of the Company and its subsidiaries.

               (v) For purposes of this Agreement,

                    (A) the term “FRC Affiliate” means First Reserve and any person directly or indirectly
controlling, controlled by or under common control with First Reserve. For purposes of the
foregoing definition, the term “controlling” “controlled by” or “under common
control with” means the power to direct or cause the direction of the management and policies
of a person or entity, whether through the ownership of voting securities, by contract or
otherwise.

                    (B) the term “affiliate” means with respect to any person, any other person directly
or indirectly controlling, controlled by or under common control with such person. For purposes of
the foregoing definition, the term “controlling” “controlled by” or “under
common control with” means the power to direct or cause the direction of the management and
policies of a person or entity, whether through the ownership of voting securities, by contract or
otherwise.

          (b) Limitation of Liability. To the fullest extent permitted by law, neither any FRC
Affiliate nor any director, officer or employee of any FRC Affiliate who may serve as an officer,
director and/or employee of the Company and/or its subsidiaries shall be liable to the Company or
its subsidiaries, except as expressly agreed in any written contract between the Company or any of
its subsidiaries and an FRC Affiliate:

               (i) by reason of any business decision or transaction undertaken by any FRC Affiliate which
may be adverse to the interests of the Company or its subsidiaries;

               (ii) by reason of any activity undertaken by any FRC Affiliate or by any other person in which
any FRC Affiliate may have an investment or other financial interest which is in competition with
the Company or its subsidiaries; or

2

 

               (iii) without limiting the effect of Section 144 of the Delaware General Corporation Law, by
reason of any transaction with any FRC Affiliate, or any transaction in which any FRC Affiliate
shall have a financial interest, unless the party seeking to assert such liability shall bear the
burden of proving, by clear and convincing evidence, that such transaction was not fair to the
Company at the time it was authorized by the Board or a committee thereof.

          (c) Competing Activities. Except as otherwise expressly provided in a written
agreement between the Company or any of its subsidiaries and an FRC Affiliate:

               (i) any FRC Affiliate and its officers, directors, agents, shareholders, members, partners,
affiliates and subsidiaries, may engage or invest in, independently or with others, any business
activity of any type or description, including without limitation those that might be the same as
or similar to the Company’s business. Without limiting the foregoing, the parties hereto
acknowledge that FRC Affiliates may from time to time compete, directly or indirectly, with the
Company, and that any such FRC Affiliate may in its sole discretion pursue such competing business
without disclosure of such competition to the Company);

               (ii) none of the Company, any subsidiary of the Company nor any other stockholder of the
Company shall have any right in or to such business activities or ventures or to receive or share
in any income or proceeds derived therefrom; and

               (iii) to the extent required by applicable law in order to effectuate the purpose of this
provision, the Company shall have no interest or expectancy, and specifically renounces any
interest or expectancy, in any such business activities or ventures.

          (d) Corporate Opportunities.

               (i) A “Company Opportunity” shall mean an investment or business opportunity or
prospective economic advantage in which the Company or its subsidiaries or First Reserve or any FRC
Affiliate could, but for the provisions of this Agreement, have an interest or expectancy. Except
as set forth below in Section 1.2(d)(ii), (A) if any FRC Affiliate or, any of its officers,
directors, agents, stockholders, members, partners, or subsidiaries acquires knowledge of, or an
interest or an expectancy in, a Company Opportunity, none of the Company and its subsidiaries shall
have any interest or expectancy, and the Company hereby renounces any interest or expectancy, in
such Company Opportunity; and (B) no such FRC Affiliate nor any of its officers, directors, agents,
stockholders, members, partners, affiliates or subsidiaries shall (1) have a duty to communicate or
present such a Company Opportunity to the Company or its subsidiaries or (2) be deemed to have
breached any fiduciary duty as a stockholder, director, or officer of the Company or otherwise by
pursuing or acquiring such Company Opportunity for itself or not communicating information
regarding such Company Opportunity to the Company.

               (ii) Notwithstanding the provisions of clause 1.2.(d)(i), the Company does not renounce any
interest or expectancy it may have in any Company Opportunity that is or was (A) offered to any
person who is both (1) an officer or director of an FRC Affiliate and (2) an officer, director or
employee of the Company, if such opportunity is expressly offered to such person in his or her
capacity as an officer, director or employee of the Company; or (B) first identified by an FRC
Affiliate solely through the disclosure of information made by or on behalf of the Company.

               (iii) Neither the alteration, amendment or repeal of this Section 1.2 nor the adoption of any
provision or amendment of the Certificate of Incorporation of the Company inconsistent with this
Section 1.2 shall eliminate or reduce the effect of this Section 1.2 in respect of any matter

3

 

occurring, or any cause of action, suit or claim that, but for this Section 1.2, would accrue or
arise prior to such alteration, amendment, repeal or adoption.

2. REGISTRATION RIGHTS.

     2.1. Definitions. For purposes of this Section 2:

          (a) Registration. The terms “register,” “registered,” and
“registration” refer to a registration effected by preparing and filing a registration
statement in compliance with the Securities Act of 1933, as amended (the “Securities Act”),
and the declaration or ordering of effectiveness of such registration statement, and shall include
Takedowns of Registrable Securities.

          (b) Registrable Securities. The term “Registrable Securities” means
(1) all shares of Common Stock now beneficially owned or hereinafter acquired by First Reserve or
any current or future employee of the Company who is party to a Management Stockholder’s Agreement
holding registration rights, and any equity of the Company or other entity acquired by First
Reserve or any such employee in exchange for shares of Common Stock, and (2) all other securities
of the Company hereinafter acquired by First Reserve from the Company. Notwithstanding the
foregoing, “Registrable Securities” shall exclude (i) any Registrable Securities sold by a
person in a transaction in which rights under this Section 2 are not assigned in accordance with
this Agreement and (ii) any Registrable Securities sold by a stockholder in a public offering,
whether sold pursuant to Rule 144 promulgated under the Securities Act, or in a registered
offering, or otherwise.

          (c) Holder. For purposes of this Section 2, the term “Holder” means
any stockholder of the Company owning of record Registrable Securities, or any permitted assignee
of record of such Registrable Securities to whom rights under this Section 2 have been duly
assigned in accordance with this Agreement.

          (d) Management Stockholder’s Agreement. The term “Management
Stockholder’s Agreement” means a Management Stockholder’s Agreement among a current or future
employee of the Company, the Company and First Reserve.

          (e) SEC. The term “SEC” means the U.S. Securities and Exchange
Commission.

          (f) Takedown. The term “Takedown” means an offering of Registrable
Securities pursuant to a Shelf Registration (as defined below), other than a sale of shares “at the
market” not involving any third party underwriter.

     2.2. Demand Registration.

          (a) Request by First Reserve. If the Company shall receive a written
request from First Reserve that the Company file a registration statement under the Securities Act
covering the registration of Registrable Securities pursuant to this Section 2.2 (a “Demand
Notice”), then the Company shall, within five (5) business days of the receipt of a Demand
Notice, give written notice of such request (“Request Notice”) to all Holders and shall use
its best efforts to effect, as soon as practicable, the registration under the Securities Act of
all Registrable Securities that First Reserve requests to be registered in the Demand Notice,
subject only to the limitations of this Section 2.2 and the Company’s obligations under Management
Stockholder’s Agreements. Notwithstanding the prior sentence, the Company shall not be obligated
to effect any such registration if the Company has, within the three (3) month period preceding the
date of such request, already effected a registration under the Securities Act pursuant to (i) this
Section 2.2, or (ii) Section 2.3 in which First Reserve participated, other than a

4

 

registration
from which all or a portion of the Registrable Securities of First Reserve were excluded pursuant
to the provisions of Section 2.3(b).

          (b) Underwriting. If First Reserve intends to distribute the Registrable
Securities covered by its request by means of an underwritten offering, then it shall so advise the
Company as a part of the Demand Notice, and the Company shall include such information in the
Request Notice. In such event, the right of any Holder to include his or her Registrable
Securities in such registration shall be conditioned upon such Holder’s participation in such
underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless
otherwise mutually agreed by First Reserve and such Holder) as provided herein. The Company and
all Holders proposing to distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or underwriters selected for
such underwriting by First Reserve. Notwithstanding any other provision of this Section 2.2, if
the managing underwriter(s) determine in good faith that marketing factors require a limitation of
the number of securities to be underwritten, the Company shall so advise all Holders of Registrable
Securities that would otherwise be registered and underwritten pursuant hereto, and the managing
underwriter(s) may exclude shares of the Registrable Securities as necessary from the registration
and the underwriting, with the number of shares to be included in the registration and the
underwriting allocated in the following manner: first to First Reserve and to each of the
other Holders requesting inclusion of their Registrable Securities in such registration statement,
on a pro rata basis, based on the total number of Registrable Securities then held by First Reserve
and each other such Holders; and second to the Company; provided that if the managing
underwriter(s) determine in good faith that allowing Holders other than First Reserve to include
their Registrable Securities in a registration statement on a pro rata basis with Registrable
Securities requested by First Reserve to be included in such registration statement would adversely
affect the distribution of the Registrable Securities being offered, then the number of shares to
be included in such registration statement and the underwriting shall be allocated in the following
manner: first to First Reserve; second to the Company; and third to each
of the other Holders requesting inclusion of their Registrable Securities in such registration
statement, on a pro rata basis, based on the total number of Registrable Securities then held by
each other such Holders. No other Registrable Securities may be included in the Registration
Statement (other than by the Company or by the Holders pursuant to Section 2.3) without First
Reserve’s consent. If, as a result of any reduction or limitation at the request of an
underwriter, a registration effected pursuant to this Section 2.2 does not include at least 80% of
the Registrable Securities that First Reserve requested to be registered in the Demand Notice, such
registration shall not constitute a demand for purposes of Section 2.2(e). For any Holder that is
a partnership, the Holder and the partners and retired partners (if any) of such Holder, or the
estates and family members of any such partners and retired partners and any trusts for the benefit
of any of the foregoing persons, and for any Holder that is a corporation, the Holder and all
corporations that are affiliates of such Holder, shall be deemed to be a single “Holder,” and any
pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of
Registrable Securities owned by all entities and individuals included in such “Holder,” as defined
in this sentence.

          (c) Shelf Registration. If the Company is eligible to register the resale
of Registrable Securities by Holders on Form S-3, then any registration under Section 2.2(a) shall,
if requested in the Demand Notice, be effected on Form S-3 pursuant to Rule 415 under the
Securities Act (or its successor) on a continuous basis for the period requested (a “Shelf
Registration”). If such a Shelf Registration is requested in the Demand Notice (such Shelf
Registration, a “Holder Shelf Registration”):

               (i) The Company shall be entitled to require that a Holder or Holders refrain from effecting
any public sales or distributions of the Registrable Securities pursuant to a Holder Shelf
Registration (a “Distribution Suspension”), if the Board reasonably determines that such
public sales or distributions would interfere in any material respect with any transaction
involving the Company that the Board reasonably determines to be material to the Company; provided,
however, that in no event shall

5

 

any one or more Distribution Suspension(s) be in effect for more
than a total of ninety (90) days in any twelve month period. The Board shall, as promptly as
practicable, give the Holders written notice of any Distribution Suspension. If the Board
institutes a Distribution Suspension, the Company shall be required
to lift that Distribution Suspension as soon as reasonably practicable after the Board
determines public sales or distributions by Holders shall not interfere with any such transaction
(and, in all events, on or before the 90 day limit set forth above).

               (ii) The Form S-3 shall provide that First Reserve and the other Holders participating in the
Shelf Registration (collectively, the “Shelf Holders”), may from time to time distribute
some or all of the Registrable Securities included in that Shelf Registration (the “Shelf
Securities”) by means of an underwritten offering (a “Shelf Underwriting”). The
Company may not participate in any such Shelf Underwriting without the prior consent of First
Reserve in its sole discretion. Only First Reserve shall have the right to initiate a Shelf
Underwriting with respect to Shelf Securities included in a Holder Shelf Registration, and each
such Shelf Underwriting shall be governed by the terms of this Section 2.2 but shall not constitute
an additional demand for purposes of Section 2.2(e).

               (iii) First Reserve shall provide the Company with written notice (a “Shelf Underwriting
Request”) if it wishes to distribute Shelf Securities pursuant to a Shelf Underwriting. Each
Shelf Underwriting Request shall indicate the proposed timing and number of Shelf Securities to be
sold by First Reserve pursuant to the Shelf Underwriting, and shall also include First Reserve’s
good faith judgment as to whether, given the proposed timing of the Shelf Underwriting, it would be
reasonably practicable for the other Shelf Holders to participate in such Shelf Underwriting. The
requirements of this Section 2.2(c)(iii) shall not apply to any Shelf Underwriting in which, in
First Reserve’s good faith judgment, it would not be reasonably practicable for the other Shelf
Holders to participate given the proposed timing of that Shelf Underwriting (each such Shelf
Underwriting, an “Overnight Deal”). No other Shelf Holder shall have a right to
participate with First Reserve in any Overnight Deal. The Company shall inform each other Holder
of any Overnight Deal promptly after its consummation.

               (iv) Within two business days of receiving a Shelf Underwriting Request for a Shelf
Underwriting that is not an Overnight Deal, the Company shall give written notice (a “Shelf
Notice”) of such Shelf Underwriting Request to all other Shelf Holders. Each Shelf Holder
desiring to include all or any part of the Shelf Securities held by such Shelf Holder in any such
Shelf Underwriting shall within two business days after receipt of the Shelf Notice so notify in
writing the Company and First Reserve, and in such notice shall inform the Company and First
Reserve of the number of Shelf Securities such Shelf Holder (each, along with First Reserve, a
“Participating Holder”) wishes to include in such Shelf Underwriting.

               (v) The Company and all Participating Holders shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriters selected for such Shelf Underwriting
by First Reserve. If the managing underwriter(s) determine in good faith that marketing factors
require a limitation of the number of securities proposed to be included in the Shelf Underwriting,
the Company shall so advise all Participating Holders, and the managing underwriter(s) may exclude
shares of the Shelf Securities as necessary from Shelf Underwriting, with the number of shares to
be included in the Shelf Underwriting allocated to First Reserve and each of the other
Participating Holders requesting inclusion of their Shelf Securities in such Shelf Underwriting on
a pro rata basis, based on the total number of Shelf Securities then held by First Reserve and each
other such Participating Holders (the defined term “Participating Holder” shall be construed for
purposes of this Section 2.2(c)(v) in the same manner as the term “Holder” is construed in the last
sentence of Section 2.2(b)); provided that if the managing underwriter(s) determine in good faith
that allowing Participating Holders other than First Reserve to include their Shelf Securities in a
Shelf Underwriting on a pro rata basis with Shelf Securities requested by First Reserve to be
included in such Shelf Underwriting would

6

 

adversely affect the distribution of the Shelf Securities
being offered, then the number of Shelf Securities to be included in such Shelf Underwriting shall
be allocated in the following manner: first to First Reserve; and second to each
of the other Participating Holders requesting inclusion of their Shelf
Securities in such Shelf Underwriting on a pro rata basis, based on the total number of Shelf
Securities then held by each other such Participating Holders.

          (d) Takedowns.

               (i) If prior to any First Reserve request for registration pursuant to Section 2.2(a), (i) the
Company shall have filed a Shelf Registration covering First Reserve’s Registrable Securities, (ii)
such Shelf Registration contemplated the intended method of distribution requested by First
Reserve, (iii) such Shelf Registration shall have registered for resale by First Reserve its
Registrable Securities, and (iv) the Shelf Registration is effective when First Reserve would
otherwise make a request for registration under Section 2.2(a), the Company shall not be required
to separately register any Registrable Securities in response to such request, and such request
shall be deemed to be a request that the Company cooperate in effecting a Takedown of the
Registrable Securities pursuant to such Shelf Registration.

               (ii) If the Company proposes to effect a Takedown from a Shelf Registration, whether for its
own account or for the account of other Holders who have Registrable Securities covered by such
Shelf Registration, or both, the Company shall give notice thereof to First Reserve, and First
Reserve may request to have its Registrable Securities included in such Takedown to the same
extent, and subject to the same limitations (including the reduction of shares included in such
Takedown), as if such Takedown were a registration pursuant to Section 2.3.

               (iii) At any time after the date of this Agreement, First Reserve may request that the Company
cooperate in effecting a Takedown of all or any portion of the Registrable Securities held by First
Reserve that remain covered by a Shelf Registration (any such request, other than in response to a
notice from the Company pursuant to Section 2.2(d)(ii), being a “Takedown Request”). If
First Reserve makes a Takedown Request:

	 	(1)	 	such Takedown Request shall count
against the number of requests for registration permitted to be
made by First Reserve only if road show assistance is provided
in the offering pursuant to Section 2.5(h);
	 
	 	(2)	 	the number of shares of
Registrable Securities of First Reserve included in such
Takedown may be reduced in the manner set forth in Section
2.2(b); and
	 
	 	(3)	 	the Company shall use its
reasonable best efforts to effectuate such Takedown as promptly
thereafter as practicable, and otherwise shall fulfill its
obligations in connection with such Takedown in accordance with
the provisions of this Agreement as if such Takedown were a
registration requested or effected pursuant to Section 2.2(a).

               (iv) In the case of a request for a Takedown or inclusion in a Takedown, all references in
this Agreement to the effective date of a Registration shall be deemed to refer to the date of
pricing of such Takedown.

7

 

          (e) Maximum Number of Demand Registrations. Except as set forth below, the
Company shall be obligated to effect only four (4) registrations pursuant to Section 2.2(a), each
of which may be a Shelf Registration. A Registration shall be effected for purposes of this
Section 2.2(e) when and
if a registration statement is declared effective by the SEC and the distribution of
securities thereunder has been completed without the occurrence of any stop order or proceeding
relating thereto suspending the effectiveness of the Registration. Notwithstanding the foregoing
sentences, there shall be no limit to the number of registrations on Form S-3 that may be requested
and obtained by First Reserve, other than demands for Shelf Registrations (each of which shall
count against the four demand registration limit).

          (f) Deferral. Notwithstanding the foregoing, if the Company shall furnish
to First Reserve a certificate signed by the President or Chief Executive Officer of the Company
stating that, in the good faith judgment of the Board, it would be materially detrimental to the
Company and its stockholders for such registration statement to be filed, then the Company shall
have the right to defer such filing for a period of not more than ninety (90) days after receipt of
the request of First Reserve; provided, however, that the Company may not utilize
this right more than once in any twelve (12) month period.

          (g) Expenses. All expenses incurred in connection with any registration
pursuant to this Section 2.2, including without limitation all federal and “blue sky” registration,
filing and qualification fees, printer’s and accounting fees, fees and disbursements of counsel for
the Company, and fees and expenses of one counsel for the Holders (selected by First Reserve) shall
be borne by the Company. Each Holder participating in a registration pursuant to this Section 2.2
shall bear such Holder’s proportionate share (based on the total number of Registrable Securities
sold in such registration other than for the account of the Company) of all discounts, commissions
or other amounts payable to underwriters or brokers in connection with such offering by the
Holders. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses
of any registration proceeding begun pursuant to this Section 2.2 if the registration request is
subsequently withdrawn at the request of First Reserve, unless First Reserve agrees that such
registration constitutes the use by it of one (1) demand registration pursuant to this Section 2.2;
provided, however, that if at the time of such withdrawal, First Reserve has
learned of a material adverse change in the condition, business, or prospects of the Company not
known to First Reserve at the time of its request for such registration and has withdrawn its
request for registration with reasonable promptness after learning of such material adverse change,
then the Company shall be required to pay all such expenses and such registration shall not
constitute the use of a demand registration pursuant to this Section 2.2.

     2.3. Piggyback Registrations.

          (a) Notices. The Company shall promptly notify First Reserve in writing (a
“Piggyback Notice”) prior to filing any registration statement under the Securities Act for
purposes of effecting an offering of securities of the Company (including, but not limited to,
registration statements relating to the initial or secondary public offerings of securities of the
Company, whether pursuant to Section 2.2 or otherwise, but excluding registration
statements with respect to an employee benefit plan or a corporate reorganization, merger or
acquisition). Subject to Section 2.3(b), the Company will afford First Reserve an opportunity to
include in such registration statement all or any part of the Registrable Securities then held by
First Reserve that are of the same class and type as the securities being offered under such
registration statement. If First Reserve desires to include in any such registration statement all
or any part of the Registrable Securities held by it, First Reserve shall within ten (10) days
after receipt of the Piggyback Notice so notify the Company in writing, and in such notice shall
inform the Company of the number of Registrable Securities it wishes to include in such
registration statement. If First Reserve decides not to include all of its Registrable Securities
in any such registration statement, it shall nevertheless continue to have the right to include any
Registrable Securities in any subsequent registration statement or registration

8

 

statements as may
be filed by the Company with respect to offerings of its securities, all upon the terms and
conditions set forth in this Agreement.

          (b) Underwriting. If a registration statement referred to in the Piggyback
Notice is for an underwritten offering, then the Company shall so advise First Reserve. In such
event, the right of First Reserve to include Registrable Securities in such a Registration shall be
conditioned upon First Reserve’s participation in such underwriting, the inclusion of its
Registrable Securities in the underwriting as provided herein and First Reserve entering into an
underwriting agreement in customary form with the managing underwriter or underwriters selected for
such underwriting. Notwithstanding any other provision of this Agreement, if the managing
underwriter(s) determine(s) in good faith that marketing factors require a limitation of the number
of shares to be underwritten, then the Company shall so advise First Reserve, and the managing
underwriter(s) may exclude shares of the Registrable Securities from the registration and the
underwriting, and the number of shares that will be included in the registration and the
underwriting shall be allocated as set forth in Section 2.2, or, if the underwriting is not
pursuant to Section 2.2, shall be allocated first to the Company, and second, to
each of the Holders requesting inclusion of their Registrable Securities in such registration
statement on a pro rata basis based on the total number of Registrable Securities then held by each
such Holder. If First Reserve disapproves of the terms of any such underwriting, it may elect to
withdraw therefrom by written notice to the Company and the underwriter(s), delivered at least ten
(10) business days prior to the effective date of the registration statement. Any Registrable
Securities excluded or withdrawn from such underwriting shall be excluded and withdrawn from the
registration. The defined term “Holder” shall be construed for purposes of this Section 2.3(b) in
the same manner as set forth in the last sentence of Section 2.2(b)).

          (c) Expenses. All expenses incurred in connection with a registration
pursuant to this Section 2.3 (excluding underwriters’ and brokers’ discounts and commissions
relating to shares sold by the Holders), including, without limitation all federal and “blue sky”
registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements
of counsel for Holders (selected by First Reserve), and fees and disbursements of counsel for the
Company, shall be borne by the Company. If it participates in a registration pursuant to this
Section 2.3, First Reserve shall bear its proportionate share (based on the total number of
Registrable Securities sold in such registration other than for the account of the Company) of all
discounts, commissions or other amounts payable to underwriters or brokers in connection with such
offering.

          (d) Not Demand Registration. Registration pursuant to this Section 2.3
shall not be deemed to be a demand registration as described in Section 2.2, unless First Reserve
specifically elects otherwise in writing. There shall be no limit on the number of times First
Reserve may request registration of Registrable Securities under this Section 2.3.

          (e) Withdrawal Right. Notwithstanding any provision contained in this
Section 2.3 to the contrary, the Company shall have the right to terminate or withdraw any
registration statement initiated by it (other than in response to a Holder Notice under Section
2.2) prior to the effectiveness of such registration statement whether or not First Reserve has
elected to include its Registrable Securities in such registration statement.

          (f) Shelf Registrations. In the event the registration commenced by the
Company pursuant to this Section 2.3 was not commenced pursuant to a Demand Notice and is a Shelf
Registration (any such Shelf Registration, a “Company Shelf Registration”): (i) the
Company and, if it requests inclusion of its Registrable Securities in such registration pursuant
to Section 2.3(a), First Reserve shall comply with the provisions of Section 2.2(c); (ii) the
piggy-back rights of First Reserve and the other provisions of Section 2.3 shall apply to both the
Company Shelf Registration and any Shelf Underwriting initiated from time to time by the Company to
distribute some or all of the Registrable Securities included

9

 

in a Company Shelf Registration; and
(iii) for purposes of Section 2.3, any such Shelf Underwriting shall be deemed to be a registration
for an underwritten offering commenced by the Company pursuant to
Section 2.3. Notwithstanding anything contained in Section 2.2(c), the Company (along with
First Reserve) shall have the right to initiate a Shelf Underwriting to distribute Registrable
Securities included in a Company Shelf Registration, and the Company shall be deemed a Shelf Holder
for purposes of any Shelf Underwriting initiated by First Reserve with respect to Registrable
Securities included in the Company Shelf Registration. If all of the Common Stock held by First
Reserve may be sold or transferred in the manner permitted under Rule 144(k) promulgated under the
Securities Act, First Reserve’s rights under this Section 2.3(f) shall not apply to any Company
Shelf Registration in which, in the Board’s good faith judgment, it would not be reasonably
practicable for First Reserve or any other person to participate given the proposed timing of that
Company Shelf Registration. The Company shall inform First Reserve of any such Company Shelf
Registration promptly after its consummation.

     2.4. Lock-ups. With respect to any underwritten offering in which the
Company or First Reserve is selling securities pursuant to Section 2.2 or 2.3 (including without
limitation the Company’s initial public offering and any Shelf Underwriting), beginning on (a) the
effective date of a registration statement filed by the Company pursuant to Section 2.2 or 2.3 (in
the case of a registration statement other than a Shelf Registration) or (b) the date of the
underwriting agreement executed in connection with a Shelf Underwriting (each an “Effective
Date”), other than as provided in the last sentence of this Section 2.4, First Reserve and the
Company each agree (unless the managing underwriters of the underwritten offering otherwise agree)
to not (i) effect any issuance, sale, transfer, assignment, pledge, conveyance (including, without
limitation, taking any short position in), or repurchase of Common Stock (or any securities of the
Company exchangeable or convertible into Common Stock) for a period of 90 days after the Effective
Date (the “Lock-up Period”) or such longer time (not to exceed an additional 90 days) as
requested by the underwriters for such offering and agreed to by First Reserve in its sole
discretion (the “Additional Period”); and (ii) the Company agrees to not file with the SEC
any other registration statement, or any supplement or amendment to a previously filed shelf
registration statement, from the Effective Date until the later of the expiration of the Lock-up
Period or the completion of the period of distribution of any underwritten offering (but not to
exceed the Additional Period). First Reserve and the Company agree to enter into customary lock-up
agreements with an underwriter consistent with the terms of this Section 2.4. The restrictions in
this Section 2.4 shall not prevent the Company from filing with the SEC registration statements
relating to any employee benefit plan, corporate reorganization, or issuance of debt that is not
convertible into equity, and shall not apply to (X) the Registrable Securities to be sold, or any
shares of stock to be sold by the Company, under any underwritten offering contemplated by Section
2.2 or 2.3; (Y) any shares of Common Stock issued by the Company upon the exercise of an option,
warrant or other security or the conversion of a security outstanding on the Effective Date; or (Z)
any shares of Common Stock issued or options or other securities to purchase or acquire Common
Stock granted pursuant to employee benefit plans of the Company existing as of the Effective Date.

     2.5. Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities under this Agreement the Company shall, as expeditiously
as reasonably possible:

          (a) Registration Statement. Subject to the provisions of Section 2.2(e),
prepare and file with the SEC a registration statement with respect to such Registrable Securities
and use its best efforts to cause such registration statement to become effective and to keep any
such registration statement (including any Shelf Registration) effective for so long as required by
the Securities Act to complete the distribution, provided however that in no event shall the
Company be required to keep a registration statement effective for greater than two years.

10

 

          (b) Amendments and Supplements. Prepare and file with the SEC such
amendments and supplements to such registration statement and the prospectus used in connection
with such
registration statement as may be necessary to comply with the provisions of the Securities Act
with respect to the disposition of all securities covered by such registration statement.

          (c) Prospectuses. Furnish to First Reserve such number of copies of a
prospectus, including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by them that are included in such registration.

          (d) Blue Sky. Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky laws of such
jurisdictions as shall be reasonably requested by First Reserve; provided that the Company
shall not be required in connection therewith or as a condition thereto to qualify to do business
or to file a general consent to service of process in any such states or jurisdictions.

          (e) Underwriting. In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement in usual and customary form
(including indemnification provisions), with the managing underwriter(s) of such offering. First
Reserve shall, if it is participating in the underwritten offering, also enter into and perform its
obligations under such an agreement.

          (f) Notification. Notify First Reserve at any time when a prospectus
relating to an offering of Registrable Securities is required to be delivered under the Securities
Act of the happening of any event as a result of which such prospectus, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing. In addition, the Company shall promptly notify First Reserve and each
underwriter, broker, dealer and placement agent participating in any offering or sale or other
distribution of securities covered by such registration statement of the issuance or threatened
issuance of any order suspending the registration or qualification of any Registrable Securities
included in such offering for disposition in any jurisdiction; use its commercially reasonable
efforts to prevent the issuance of any such threatened order and, if any such order is issued, use
its commercially reasonable efforts to obtain the lifting or withdrawal of such order at the
earliest possible moment and promptly notify First Reserve and each such underwriter, broker,
dealer and placement agent of any lifting or withdrawal.

          (g) Opinion and Comfort Letter. Furnish, at the request of First Reserve or
of any underwriter in connection therewith, on the date or dates requested by First Reserve or such
underwriter, (i) an opinion, dated as of such date, of the counsel representing the Company for the
purposes of such registration, in form and substance as is customarily given to underwriters in an
underwritten public offering and reasonably satisfactory to First Reserve, addressed to the
underwriters, if any, and to First Reserve and (ii) a “comfort” letter dated as of such date, from
the independent certified public accountants of the Company, in form and substance as is
customarily given by independent certified public accountants to underwriters in an underwritten
public offering and reasonably satisfactory to First Reserve, addressed to the underwriters, if
any, and, if permissible, to First Reserve.

          (h) Road Shows. To the extent reasonably requested by First Reserve, cause
the appropriate members of the management and employees of the Company to participate in meetings,
diligence sessions, and road shows.

11

 

          (i) Maintenance of Listed Status. Following its initial public offering,
the Company shall use its best efforts to (i) cause all Registrable Securities to be listed on the
securities exchange or
automated quotation system on which the Company’s Common Stock is initially listed; and (ii)
to maintain its status as a listed company on such exchange or quotation system or such other major
national securities exchange as the Company’s Board of Directors may determine. In the event the
Company should be de-listed from such exchange or quotation system, the Company shall use its best
efforts to regain its status as a listed company on such exchange or quotation system as promptly
as is reasonably possible.

          (j) Additional Actions. Take all other actions which are reasonably
necessary or which may be reasonably requested by First Reserve or any underwriter, broker, dealer
or placement agent participating in any offering or sale or other distribution of securities
covered by such registration statement to effect the registration and qualification of the
Registrable Securities covered by such registration statement and to facilitate the disposition
thereof in accordance with the respective plans of distribution of the selling Holders.

     2.6. Indemnification. In the event any Registrable Securities owned by
First Reserve are included in a registration statement under Sections 2.2 or 2.3:

          (a) By the Company. To the extent permitted by law, the Company will
indemnify and hold harmless First Reserve, the partners, officers and directors of First Reserve,
any underwriter (as determined in the Securities Act) for First Reserve and each person, if any,
who controls First Reserve or underwriter within the meaning of the Securities Act or the
Securities Exchange Act of 1934, as amended, (the “Exchange Act”), against any losses,
claims, damages, or liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the
following statements, omissions or violations (collectively a “Violation”):

     (i) any untrue statement or alleged untrue statement of a material fact
contained in such registration statement, including any preliminary prospectus or
final prospectus contained therein or any amendments or supplements thereto;

     (ii) the omission or alleged omission to state therein a material fact required
to be stated therein, or necessary to make the statements therein not misleading, or

     (iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any federal or state securities law or any rule or regulation
promulgated under the Securities Act, the Exchange Act or any federal or state
securities law in connection with the offering covered by such registration
statement;

and the Company will reimburse First Reserve and each such partner, officer or director,
underwriter or controlling person for any legal or other expenses reasonably incurred by them, as
incurred, in connection with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the indemnity agreement contained in this subsection 2.6(a)
shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company, which consent shall not be
unreasonably withheld, nor shall the Company be liable in any such case for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished expressly for use in
connection with such registration by First Reserve or such partner, officer, director, underwriter
or controlling person of First Reserve.

12

 

          (b) By First Reserve. To the extent permitted by law, First Reserve will
indemnify and hold harmless the Company, each of its directors, each of its officers who have
signed the registration
statement, each person, if any, who controls the Company within the meaning of the Securities
Act and any underwriter, against any losses, claims, damages or liabilities (joint or several) to
which the Company or any such director, officer, controlling person or underwriter may become
subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based
upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs
in reliance upon and in conformity with written information furnished by First Reserve concerning
it expressly for use in connection with such registration; and First Reserve will reimburse any
legal or other expenses reasonably incurred by the Company or any such director, officer,
controlling person or underwriter in connection with investigating or defending any such loss,
claim, damage, liability or action: provided, however, that the indemnity agreement
contained in this subsection 2.6(b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the consent of First
Reserve, which consent shall not be unreasonably withheld; and provided, further, that the total
amounts payable in indemnity by First Reserve under this Section 2.6(b) in respect of any Violation
shall not exceed the net proceeds received by First Reserve in the registered offering out of which
such Violation arises.

          (c) Notice. Promptly after receipt by an indemnified party under this
Section 2.6 of notice of the commencement of any action (including any governmental action), such
indemnified party will, if a claim in respect thereof is to be made against any indemnifying party
under this Section 2.6, deliver to the indemnifying party a written notice of the commencement
thereof and the indemnifying party shall have the right to participate in, and, to the extent the
indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to
assume the defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party shall have the right to retain its own counsel, with the
fees and expenses of no more than one separate counsel to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the indemnifying party would be
inappropriate due to actual or potential conflict of interests between such indemnified party and
any other party represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of any such action
shall relieve such indemnifying party of liability to the indemnified party under this Section 2.6
to the extent the indemnifying party is prejudiced as a result thereof, but the omission so to
deliver written notice to the indemnified party will not relieve it of any liability that it may
have to any indemnified party otherwise than under this Section 2.6.

          (d) Contribution. In order to provide for just and equitable contribution
to joint liability under the Securities Act in any case in which either (i) First Reserve
exercising rights under this Agreement, or any controlling person of First Reserve, makes a claim
for indemnification pursuant to this Section 2.6 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be enforced in such
case notwithstanding the fact that this Section 2.6 provides for indemnification in such case, or
(ii) contribution under the Securities Act may be required on the part of First Reserve or any such
controlling person in circumstances for which indemnification is provided under this Section 2.6;
then, and in each such case, the Company and First Reserve will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution from others) in
such proportion so that First Reserve is responsible for the portion represented by the percentage
that the public offering price of its Registrable Securities offered by and sold under the
registration statement bears to the public offering price of all securities offered by and sold
under such registration statement and the Company is responsible for the remaining portion;
provided, however, that, in any such case: (A) First Reserve will not be required
to contribute any amount in excess of the public offering price of all such Registrable Securities
offered and sold by First Reserve pursuant to

13

 

such registration statement; (B) no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation, and (C) in determining relative
fault, due consideration shall be given to whether any untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact relates to information
provided by the Company on the one hand or First Reserve on the other.

          (e) Survival. The obligations of the Company and First Reserve under this
Section 2.6 shall survive until the earlier of (i) the one year anniversary of the expiration of
all applicable statutes of limitation or extensions of such statutes or (ii) the termination of
First Reserve Fund X, L.P.

     2.7. Furnish Information.

          (a) First Reserve, as a condition to its participation in any registration or
offering contemplated by this Section 2, agrees to furnish to the Company such information
regarding itself, the Registrable Securities held by it, and the intended method of disposition of
such securities as shall be reasonably requested by the Company or otherwise required to timely
effect the Registration of their Registrable Securities.

          (b) Upon the reasonable request of the Company, First Reserve shall inform the
Company what Registrable Securities other than Common Stock is owned by First Reserve.

     2.8. Rule 144 Reporting; S-3 Eligibility. With a view to making available
the benefits of certain rules and regulations of the SEC which may at any time permit the sale of
“Restricted Securities” (used herein as defined in Rule 144 under the Securities Act) to the public
without registration, and to be eligible to use Form S-3, the Company agrees to:

          (a) make and keep public information available, as those terms are understood and
defined in Rule 144 under the Securities Act, at all times during which the Company is subject to
the reporting requirements of the Exchange Act;

          (b) file with the SEC in a timely manner (including any permissible extensions under
Rule 12b-25 under the Exchange Act or any successor rule) all reports and other documents required
of the Company under the Securities Act and the Exchange Act (at all times during which the Company
is subject to such reporting requirements); and

          (c) so long as First Reserve owns any Restricted Securities, to furnish to First
Reserve forthwith upon request a written statement by the Company as to its compliance with the
reporting requirements of said Rule 144 and with regard to the Securities Act and the Exchange Act
(at all times during which the Company is subject to such reporting requirements), a copy of the
most recent annual or quarterly report of the Company, and such other reports and documents of the
Company and other information in the possession of or reasonably obtainable by the Company as First
Reserve may reasonably request in availing itself of any rule or regulation of the SEC allowing
First Reserve to sell any such securities without registration.

     2.9. Impact of Merger. In the event the Company merges with or into another
entity, the terms of this Section 2 shall apply to any equity received by First Reserve in
connection with the merger in exchange for the Common Stock or other Registrable Securities held by
First Reserve immediately prior to the consummation of the merger.

14

 

3. ASSIGNMENT, AMENDMENT AND TERMINATION. 

     3.1. Assignment. Notwithstanding anything herein to the contrary:

          (a) Registration Rights. The registration rights of First Reserve under
Section 2 of this Agreement may be assigned in connection with any Transfers made by First Reserve;
provided, however, that no party may be assigned any of the foregoing rights unless
(i) the Company is given written notice by the assigning party at the time of such assignment
stating the name and address (which shall be deemed the address for notice until changed in
accordance with Section 5.1) of the assignee and identifying the securities of the Company as to
which the rights in question are being assigned and (ii) any such assignee shall have agreed to be
subject to all the terms and conditions of this Agreement, including without limitation the
provisions of Section 2 and this Section 3. Any assignment not made in accordance with the
foregoing terms shall not be effective.

          (b) Management and Information Rights. The management rights under Section
1 of this Agreement and information rights under Section 2.8(c) of this Agreement may be assigned
by First Reserve to another FRC Affiliate, but may not otherwise be assigned.

     3.2. Amendment of Rights. This Agreement may be amended only by a written
instrument signed by each of the parties hereto. If either party fails to enforce any of the
provisions of this Agreement or any rights or fails to exercise any election provided in this
Agreement, it will not be considered to be a waiver of those provisions, rights or elections or in
any way affect the validity of this Agreement. The failure of any party to exercise any of these
provisions, rights or elections will not preclude or prejudice such party from later enforcing or
exercising the same or any other provision, right or election which it may have under this
Agreement.

4. LEGEND. 

     Each certificate representing shares of capital stock of the Company now or hereafter owned by
a First Reserve shall be endorsed with the following legend, to the extent so required by the
Securities Act or any applicable securities law:

ANY APPLICABLE STATE SECURITIES LAWS.
