(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 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 6, 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 of any Additional Shares and the 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 jurisdictions specified pursuant to Section 6(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 costs and expenses incident to listing the Shares on the Nasdaq Global 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 and the Selling Stockholders 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 and one counsel for the Selling Stockholders (selected by Chart Holdings); and (xi) all other costs and expenses incident to the performance by the Company and/or the Selling Stockholders of their respective 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; provided, further, that all underwriting discounts, commissions and other amounts payable to underwriters or brokers for Firm Shares will be borne by the respective Selling Stockholders.

(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 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 Additional Shares in the manner specified in the Prospectus under “Use of Proceeds.”

7. Selling Stockholders’ Agreements. Each of the Selling Stockholders agrees severally, but not jointly, with each Underwriter that:

(a) The Selling Stockholder 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.

(b) Other than as contemplated under this Agreement, the Selling Stockholder agrees that it 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.

8. 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.

9. Conditions to the Obligations of the Underwriters. The obligations of the Selling Stockholders to sell the Firm Shares and the obligations of the Company to sell any Additional Shares, respectively, 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 and the Selling Stockholders contained herein that are not qualified by materiality and to the accuracy of the representations and warranties of the Company and the Selling Stockholders 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 and the Selling Stockholders made in any certificates pursuant to the provisions hereof, to the performance by the Company and the Selling Stockholders of their respective obligations hereunder and to the following additional conditions:

All references in this Section 9(g) to the Time of Sale Prospectus, the Prospectus and Registration Statement include any amendment or supplement thereto at the date of the applicable letter.

(h) 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 the Management Selling Stockholders, each listed on Schedule V 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.

(i) 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

10. 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 9 hereof is not satisfied, because of any termination pursuant to Section 13 hereof or because of any refusal, inability or failure on the part of the Company or the Selling Stockholders 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 12 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.

11. 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 8) 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 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 (i) one or more Selling Stockholders or (ii) 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 11 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 Selling Stockholder severally, and not jointly, 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, 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 each Selling Stockholder will only 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 the Prospectus, or in any amendment or supplement thereto, in reliance upon and in conformity with written information furnished by or on behalf of the Selling Stockholders specifically for inclusion therein. The liability of each Selling Stockholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the aggregate net proceeds from the sale of the Shares sold by such Selling Stockholder under this Agreement. The Underwriters acknowledge that the information in any preliminary prospectus, the Time of Sale Prospectus and the Prospectus contained under the caption “Principal and Selling Stockholders,” insofar as it relates to the Selling Stockholders and the beneficial ownership of the Selling Stockholders’ shares, constitutes the only information furnished in writing by or on behalf of the Selling Stockholders for inclusion in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, or in any amendment of supplement thereto. This indemnity agreement will be in addition to any liability that the Selling Stockholders may otherwise have. The Selling Stockholders shall not be liable under this Section 11 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 Selling Stockholders, which consent shall not be unreasonably withheld.

(c) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company and the Selling Stockholders, the Company’s directors, officers and Affiliates, and each person who controls the Company or the Selling Stockholders within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company and the Selling Stockholders 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 and the Selling Stockholders acknowledge that, under the heading “Underwriting,” the table after the first paragraph, the eleventh, twelfth, thirteen and fourteenth 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.

(d) Promptly after receipt by an indemnified party under this Section 11 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 11, 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), (b) or (c) 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), (b) or (c) 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 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 and any such separate firm for the Selling Stockholders and any control person shall be designated in writing by the Selling Stockholders. 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.

(e) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 11 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Selling Stockholders 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, the Selling Stockholders 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 and the Selling Stockholders 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, the Selling Stockholders 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 and the Selling Stockholders 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 and a Selling Stockholder shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Company or such Selling Stockholder, 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 omission to state a material fact relates to information provided by the Company or the Selling Stockholders 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, the Selling Stockholders 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 (e), 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 11 are several in proportion to their respective obligations and not joint. The liabilities of each Selling Stockholder in this paragraph (e) shall be limited to the amount equal to the net proceeds from the sale of the Shares sold by such Selling Stockholder under the Agreement. For purposes of this Section 11, 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 and each person who controls a Selling Stockholder within the meaning of either the Securities Act or the Exchange Act shall have the same rights to contribution as such Selling Stockholder, subject in each case to the applicable terms and conditions of this paragraph (e).

12. 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 II 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 II hereto, the Company and the Selling Stockholders 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 and the Selling Stockholders 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, the Company or the Selling Stockholders. In the event of a default by any Underwriter as set forth in this Section 12, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Underwriters, the Company, the Selling Stockholders and their respective counsel shall determine in order that the required changes in the Time of Sale Prospectus, the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or the Selling Stockholders or any nondefaulting Underwriter for damages occasioned by its default hereunder.

13. 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).

14. 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, the Selling Stockholders 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 and the Selling Stockholders acknowledge 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, the Selling Stockholders or any other person, (ii) the Underwriters owe the Company and the Selling Stockholders 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 and the Selling Stockholders. The Company will not, and each Selling Stockholder 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 or any Selling Stockholder, in connection with such transaction or the process leading thereto.

15. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, the Selling Stockholders or their respective 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, the Company or the Selling Stockholders or any of the indemnified persons referred to in Sections 11 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 10 and 11 hereof shall survive the termination or cancellation of this Agreement.

Dear Sirs and Mesdames:

The undersigned understands that Xxxxxx Xxxxxxx & Co. Incorporated (“Xxxxxx Xxxxxxx”), Xxxxxx Brothers Inc. (“Xxxxxx”) and Xxxxxxx, Xxxxx & Co. (“Goldman,” together with Xxxxxx Xxxxxxx and Xxxxxx, the “Managers”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with FR X Chart Holdings LLC, a Delaware limited liability company (“Chart Holdings”) and the Individuals named in Schedule I to the Underwriting Agreement (“Management Stockholders”, and together with Chart Holdings, the “Selling Stockholders”), providing for the public offering (the “Public Offering”) by the several underwriters named in Schedule II to the Underwriting Agreement (the “Underwriters”), of 12,612,648 shares (the “Shares”) of the Common Stock, par value $0.01 (the “Common Stock”) of Chart Industries, Inc., a corporation organized under the laws of Delaware (the “Company”).

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 90 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) the exercise of such number of options or warrants outstanding on the date hereof to acquire shares of Common Stock that will provide the undersigned with such number of shares of Common Stock, after taking into account the number of shares of Common Stock owned by the undersigned, that is equal to the number of shares of Common Stock the undersigned has undertaken to sell in accordance with the terms of the Underwriting Agreement, (C) transfers of shares of Common Stock or any security convertible, exchangeable for or exercisable into Common Stock as a bona fide gift or gifts as a result of the operation of law or testate or intestate succession, (D) 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 (E) 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 (C), (D) or (E), (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 90 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 and the Selling Stockholders notify the undersigned in writing that they do not intend to proceed with the Public Offering, if the Underwriting Agreement does not become effective on or before August 31, 2007, 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, the Selling Stockholders 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 market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Company, the Selling Stockholders, and the Underwriters.

Ladies and Gentlemen:

We have acted as counsel to Chart Industries, Inc., a Delaware corporation (the “Company”), FR X Chart Holdings LLC, a Delaware limited liability company (“Chart Holdings”), and certain members of management of the Company named in Schedule I to the Underwriting Agreement (as defined below) (the “Management Stockholders” and, together with Chart Holdings, the “Selling Stockholders”) in connection with the purchase by you of (A) an aggregate of 12,612,513 shares (the “Selling Stockholder Shares”) of common stock, par value $0.01 per share of the Company (“Common Stock”), from the Selling Stockholders and (B) up to an aggregate of 1,891,876 shares (the “Over-Allotment Shares” and, together with the Selling Stockholder Shares, the “Shares”) of Common Stock from the Company to be issued to cover over-allotments, pursuant to the Underwriting Agreement, dated June 6, 2007, among you, the Company and the Selling Stockholders (the “Underwriting Agreement”).

We have examined the Registration Statement on Form S-1 (File No. 333-141730) (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 June 6, 2007 (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 May 30, 2007 (the “Preliminary Prospectus”), included in the Registration Statement immediately prior to the time the Registration Statement became

Xxxxxxx, Xxxxx & Co. Et. Al.		-5-

effective under the Securities Act; the Underwriting Agreement; and each Custody Agreement (the “Custody Agreements”) between each of the Management Stockholders and Chart Industries, Inc., as custodian (the “Custodian”), and each Power of Attorney (the “Powers of Attorney”) between each of the Management Stockholders and Xxxxxxx X. Xxxxxx and Xxxxx X. Xxxxxx, Xx., as the attorneys-in-fact named therein (the “Attorneys-in-Fact”), relating to the Shares to be sold to the Underwriters by such Management Stockholders. We also have examined the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), the Company’s Amended and Restated By-Laws (the “By-Laws”) and 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 the Selling Stockholders, 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. In addition, in connection with our opinion set forth in paragraphs 4 and 5 below, we have assumed that (i) The Depository Trust Company (“DTC”) is a “securities intermediary” as defined in Section 8-102 of the Uniform Commercial Code as in effect in the State of New York (the “New York UCC”), and the State of New York is the “securities intermediary’s jurisdiction” of DTC for purposes of Section 8-110 of the New York UCC, (ii) the Shares to be sold by the Selling Stockholders are registered in the name of DTC or its nominee, and DTC or another person on behalf of DTC maintains possession of certificates representing those Shares, (iii) DTC indicates by book entries on its books that security entitlements with respect to the Shares to be sold by the Selling Stockholders have been credited to the Underwriters’ securities accounts and (iv) the Underwriters are purchasing the



Xxxxxx Xxxxxxx & Co. Incorporated Xxxxxx Brothers Inc.
Xxxxxxx, Xxxxx & Co. Et. Al.		-6-

Shares to be sold by the Selling Stockholders without notice of any adverse claim (within the meaning of the New York UCC).

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

2. The Shares to be sold by the Selling Stockholders have been duly authorized by the Company and are validly issued, fully paid and nonassessable.

3. Chart Holdings has full limited liability company power, right and authority to sell the Shares to be sold by it; and upon the payment and transfer contemplated by the Underwriting Agreement, the Underwriters will acquire a security entitlement with respect to the Shares to be sold by Chart Holdings and no action based on an adverse claim may be asserted against the Underwriters.

4. Upon the payment and transfer contemplated by the Underwriting Agreement, the Underwriters will acquire a security entitlement with respect to the Shares to be sold by the Management Stockholders and no action based on an adverse claim may be asserted against the Underwriters.

5.

6. 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.

14. 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 Limited Liability Company Act or, to our knowledge, any federal or New York court or any Delaware court acting pursuant to the Delaware Limited Liability Company Act is required for the sale of the Shares to be sold by Chart Holdings and the compliance by Chart Holdings with all of the provisions of the Underwriting Agreement, except for the registration under the Securities Act of the Shares to be sold by it, 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 such Shares by the Underwriters.

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 and Chart Holdings, representatives of Ernst & Young LLP, counsel to the Company, your representatives and your counsel in the course of the preparation by the Company of the Registration Statement, the Pricing Disclosure Package and the Prospectus and also reviewed certain corporate and other records and documents furnished to us by the Company and the Selling Stockholders, as well as the documents delivered to you at the closing. Certain of such corporate and other records and documents were not in English or were governed by the laws of jurisdictions other than the United States and, accordingly, we necessarily relied upon directors, officers and employees of the Company and its subsidiaries and other persons in evaluating such corporate and other records and documents. Based upon our review of the Registration Statement, the Pricing Disclosure Package and the Prospectus, our participation in the conferences referred to above, our review of the corporate and other records and documents as described above, as well as our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder:

	(i)		we advise you that the Registration Statement, as of the date it became effective under the Securities Act, and the Prospectus, as of June 6, 2007, appeared, on its face, to be appropriately responsive, in all material respects, to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no view with respect to the financial statements or other financial data contained in, or omitted from, the Registration Statement or the Prospectus; and

	(ii)		nothing has come to our attention that causes us to believe that (a) the Registration Statement, as of the date it became effective under the Securities Act, contained any untrue statement of a material fact or omitted to state any material

fact required to be stated therein or necessary in order to make the statements therein not misleading, (b) the Pricing Disclosure Package, as of 4:45 p.m. on June 6, 2007, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (c) the Prospectus, as of June 6, 2007 or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any 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 we express no belief in any of clauses (a), (b) or (c) above with respect to the financial statements or other financial data contained in, or omitted from, the Registration Statement, the Pricing Disclosure Package or the Prospectus.

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 sale of an aggregate of 12,612,513 shares (the “Shares”) of the Company’s Common Stock, par value $0.01 per share (the “Common Stock”), pursuant to the Underwriting Agreement, dated June 6, 2007 (the “Underwriting Agreement”), among you, the Company, FR X Chart Holdings LLC, a Delaware limited liability company (“Chart Holdings”) and the Individuals named in Schedule I of the Underwriting Agreement (the “Management Selling Stockholders,” and together with Chart Holdings, the “Selling Stockholders”). Unless otherwise defined herein, terms defined in the Underwriting Agreement are used herein with the same meaning.

This opinion letter is delivered to you pursuant to Sections 9(a) and 9(b) of the Underwriting Agreement. Concurrent with the delivery of this opinion Xxxxxxx Xxxxxxx & Xxxxxxxx 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

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. 333-141730) (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 May 30, 2007 (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 June 6, 2007 (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 pricing information included in Schedule III to the Underwriting Agreement (such scheduled pricing information, together with the Preliminary Prospectus, the “Pricing Disclosure Package”);

(vii) the Custody Agreements and Irrevocable Powers of Attorney of Selling Stockholders executed by each of the Management Selling Stockholders in connection with the transactions contemplated by the Underwriting Agreement (the “Custody Agreements and Powers of Attorney”) and

(viii) 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 reports from the transfer agent for the Company. My opinions set forth in paragraphs 11 and 12 below accordingly are based solely on a review of the representations and warranties made by the Management Selling Stockholders in the Underwriting Agreement, the Custody Agreements and the Powers of Attorney.

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 Closing Date 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 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 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.

11. To my knowledge, the sale of the Shares by each Management Selling Stockholder and the execution and delivery by each Management Selling Stockholder of, and the performance by such Management Selling Stockholder of its obligations under, the Underwriting Agreement and the consummation of the transactions contemplated by the Underwriting Agreement will not contravene any provision of Applicable Law or any material agreement or instrument binding upon such Management Selling Stockholder or any material judgment, order or decree of any governmental body, agency or court having jurisdiction over such Management Selling Stockholder, and, to my knowledge, no consent, approval, authorization, registration, or qualification with any governmental body or agency

is required for the sale of the Shares by each Management Selling Stockholder or the performance by such Management Selling Stockholder of its obligations under the Underwriting Agreement, except for the registration under the Securities Act of the Shares and such consents, approvals, authorizations, registrations or qualifications as may be required under state or foreign securities or Blue Sky laws or the rules and regulations of the National Association of Securities Dealers, Inc. in connection with offer and sale of the Shares and such consents, approvals, authorizations, registrations or qualifications that would not reasonably be expected to have a material adverse effect on the financial condition of such Management Selling Stockholder.

12. To my knowledge, each of the Management Selling Stockholders has valid title to, or a valid security entitlement in respect of, the Shares to be sold by such Management Selling Stockholder free and clear of all security interests, claims, liens, equities and other encumbrances other than those implied by law.

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 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 4:45 p.m. on June 6, 2007, 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,

Ladies and Gentlemen:

The undersigned beneficial shareholder of Chart Industries, Inc., a Delaware corporation (the “Company”), understands that it is contemplated that certain shareholders of the Company, including the undersigned (the “Selling Stockholders”), will sell Common Stock, $0.01 par value (“Common Stock”), of the Company to certain underwriters (the “Underwriters”) represented by Xxxxxx Xxxxxxx & Co.

You are authorized and directed to take all necessary action to: (a) cause the Shares to be transferred on the books of the Company into such names as the Attorneys, or any one of them, or the Managers shall have instructed you to be registered in such names and in such denominations as the Attorneys, or any one of them, or the Managers shall have instructed you in order to effect the sale of the Shares, (b) instruct National City Bank, the transfer agent and registrar for the Company (the “Transfer Agent”), to exchange the certificates for such Shares for book-entry security entitlements for delivery to the Underwriters, (c) to deliver to or for the account of the Underwriters the book-entry security entitlements for such Shares against receipt by you of the purchase price to be paid therefor, (d) pay, out of the proceeds of such sale, the aggregate Option Price (as defined in the Stock Incentive Plan) for the Shares (as defined in the
