Ladies and Gentlemen:

Chart Industries, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several purchasers named in Schedule I hereto (the “Initial Purchasers”), for whom Xxxxxx Xxxxxxx & Co. LLC and X.X. Xxxxxx Securities LLC are acting as representatives (the “Representatives”), $225,000,000 in aggregate principal amount of the Company’s 1.00% Convertible Senior Subordinated Notes due 2024 (the “Initial Securities”).

The Initial Securities will be issued pursuant to the provisions of an indenture, to be dated as of the Closing Date (as defined below) (the “Indenture”), between the Company and Xxxxx Fargo Bank, National Association, as trustee (the “Trustee”).

In addition, the Company has granted to the Initial Purchasers an option to purchase up to an additional $33,750,000 in aggregate principal amount of its 1.00% Convertible Senior Subordinated Notes due 2024 on the terms and conditions and for the purposes set forth in Section 2 (the “Option Securities” and, together with the Initial Securities, the “Securities”). The Securities will be convertible into duly and validly issued, fully paid and non-assessable shares of common stock, par value $0.01 per share (the “Common Stock”), of the Company (such shares, the “Conversion Shares”), cash or a combination of cash and Conversion Shares, at the Company’s election, on the terms, and subject to the conditions, set forth in the Indenture.

In connection with the offering of the Initial Securities, the Company is separately entering into convertible note hedge and warrant transactions with certain financial institutions, including one or more of the Initial Purchasers (the “Call Spread Counterparties”) pursuant to convertible note hedge confirmations (the “Base Bond Hedge Confirmations”) and warrant confirmations (the “Base Warrant Confirmations” and, together with the Base Bond Hedge Confirmations, the “Base Call Spread Confirmations”), respectively, each to be dated the date hereof, and in connection with any exercise by the Initial Purchasers of their option to purchase any Option Securities, the Company and the Call Spread Counterparties expect to enter into additional convertible note hedge and warrant transactions pursuant to additional convertible note hedge confirmations (the “Additional Bond Hedge Confirmations”)

and additional warrant confirmations (the “Additional Warrant Confirmations” and, the Additional Warrant Confirmations together with the Additional Bond Hedge Confirmations, the “Additional Call Spread Confirmations”), respectively, each to be dated the date on which the Initial Purchasers exercise their option to purchase such Option Securities. We refer to the Base Call Spread Confirmations and the Additional Call Spread Confirmations collectively herein as the “Call Spread Confirmations.”

The Company understands that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Time of Sale Memorandum (as defined herein) and agrees that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Time of Sale Memorandum (the first time when sales of the Securities are made is referred to as the “Time of Sale”). The Securities will be offered without being registered under the Securities Act of 1933, as amended (the “Securities Act”), to persons reasonably believed to be qualified institutional buyers in compliance with the exemption from registration provided by Rule 144A under the Securities Act (“Rule 144A”). Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A). The Company hereby confirms that it has authorized the use of the Time of Sale Memorandum, the Final Memorandum (as defined herein) by the Initial Purchasers in connection with the offer and sale of the Securities by the Initial Purchasers.

As used herein, the terms “Preliminary Memorandum,” “Time of Sale Memorandum” and “Final Memorandum” shall include the documents, if any, incorporated by reference therein prior to the Time of Sale.

Supplement, any Additional Written Offering Communication, General Solicitation or the Final Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Initial Purchaser, but only with reference to information relating to such Initial Purchaser furnished to the Company by such Initial Purchaser expressly for use in the Preliminary Memorandum, the Pricing Supplement, any Additional Written Offering Communication or the Final Memorandum (or any amendment or supplement thereto). The Company hereby acknowledges that the only information that the Initial Purchasers have furnished to the Company expressly for use in the Preliminary Memorandum, the Time of Sale Memorandum, any Additional Written Communication set forth in Schedule II hereto or the Final Memorandum (or any amendment or supplement thereto) are the statements set forth in the first paragraph under the caption “Price Stabilization and Short Positions; Purchase of Common Stock” in the “Plan of Distribution” section in the Preliminary Memorandum and the Final Memorandum.

In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party, (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnified party, or (iv) the named parties to any such proceeding (including any impleaded parties) include both the

indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party 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 such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 8(a) hereof, and by the Company, in the case of parties indemnified pursuant to Section 8(b) hereof. The indemnifying party 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 indemnifying party agrees to indemnify the indemnified party from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party 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 such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement unless such indemnifying party has (A) reimbursed all undisputed amounts and only failed to reimburse amounts disputed in good faith and (B) provided detail regarding the reasons for the failure to reimburse amounts requested by the indemnified party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) hereof is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(d)(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 8(d)(i) above but also the relative fault of the Company on the one hand and of the Initial

Purchasers on the other hand in connection with the 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 Initial Purchasers on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total discounts and commissions received by the Initial Purchasers bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and of the Initial Purchasers on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, or by the Initial Purchasers, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have purchased hereunder as set forth opposite their names in Schedule I hereto, and not joint.

(e) The Company and the Initial Purchasers agree that it would not be just or equitable if contribution pursuant to Section 8(d) hereof were determined by pro rata allocation (even if the Initial Purchasers 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 8(d) hereof. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) hereof shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 remedies provided for in this Section 8 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.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement 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 Initial Purchaser, any person controlling any Initial Purchaser or any affiliate of any Initial Purchaser or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

9. Termination. The Representatives may terminate this Agreement by notice given by you to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (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, the NYSE MKT, or the NASDAQ Global 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 judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Time of Sale Memorandum or the Final Memorandum.

10. Effectiveness; Defaulting Initial Purchasers. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase is not more than one tenth of the aggregate principal amount of Securities to be purchased on such date, the other Initial Purchasers shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Securities set forth opposite the names of all such non defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date; provided that in no event shall the principal amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one ninth of such principal amount of Securities without the written consent of such Initial Purchaser. If, on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Securities which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs is more than one tenth of the aggregate principal amount of Securities to be purchased on the Closing Date, and arrangements satisfactory to the non-defaulting Initial Purchasers and the Company for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non defaulting Initial Purchaser or of the Company except that the provisions of Sections 6(g), 8 and 11 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Company

shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Time of Sale Memorandum, the Final Memorandum or in any other documents or arrangements may be effected. As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 10. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

11. Reimbursement of the Expenses of the Initial Purchasers. If this Agreement shall be terminated by the Initial Purchasers pursuant to clause (ii) of Section 9 or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement (in each case other than (x) a termination pursuant to clauses (i), (iii), (iv) or (v) of Section 9 or (y) a termination pursuant to Section 10 (with respect to the defaulting Initial Purchaser only)), the Company will reimburse the Initial Purchasers, severally, upon demand for all out of pocket expenses (including the fees and reasonable disbursements of their counsel) reasonably incurred by such Initial Purchasers in connection with this Agreement or the offering contemplated hereunder.

12. 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 Securities, represents the entire agreement between the Company and the Initial Purchasers with respect to the preparation of the Preliminary Memorandum, the Time of Sale Memorandum, the Final Memorandum, the conduct of the offering, and the purchase and sale of the Securities.

(b) This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Initial Purchasers, or any of them, with respect to the subject matter hereof.

(c) The Company acknowledges that in connection with the offering of the Securities: (i) the Initial Purchasers have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Initial Purchasers owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement) if any, (iii) the Initial Purchasers may have interests that differ from those of the Company and (iv) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate. The Company waives to the full extent permitted by applicable law any claims it may have against the Initial Purchasers arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

13. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the indemnified parties referred to in Section 8 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

16. Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by the Representatives on behalf of the Initial Purchasers, and any such action taken by the Representatives shall be binding upon the Initial Purchasers.

17. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

(a) Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party submits to the jurisdiction of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties waive any objection to the laying of venue of any Related Proceeding in the Specified Courts and waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum.

FORM OF LOCK UP AGREEMENT

Ladies and Gentlemen:

The undersigned understands that you, Xxxxxx Xxxxxxx & Co. LLC and X.X. Xxxxxx Securities LLC, as representatives (the “Representatives”) of the several initial purchasers named in Schedule I thereto (the “Initial Purchasers”), propose to enter into an Purchase Agreement (the “Purchase Agreement”) with Chart Industries, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) by the Initial Purchasers of Convertible Senior Subordinated Notes due 2024 of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Purchase Agreement.

In consideration of the Initial Purchaser’s agreement to purchase and make the Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representatives, the undersigned will not, during the period commencing on the date hereof and ending ninety (90) days after the date of the Final Memorandum, (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, $0.01 per share par value, of the Company (the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be, or are, issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any offer, sale, pledge or disposition, (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 the Common Stock or such other securities, 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 or (3) during the period ending ninety (90) days after the date of the Final Memorandum, 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. The foregoing shall not apply to (1) withholding (or sale to the Company) of Common Stock to satisfy tax obligations in connection with the vesting of equity compensation awards, including restricted stock, performance units and, in the case of the Company’s directors, awards of Common Stock pursuant to the Company’s director compensation program, or exercises of options to acquire shares of Common Stock, including sales made to the Company in connection with the cashless exercise of options, in each case as described in each of the Time of Sale Memorandum and the Final Memorandum or (2) transfers of shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock (A) as a bona fide gift or (B) by will or intestate succession to a member or members of the undersigned’s immediate family or to a trust, formed for the benefit of any such

A-1

person; provided that in the case of any transfer pursuant to sub-clauses (A) and (B) above, (i) each transferee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act or other public announcement shall be required or shall be voluntarily made during the 90-day restricted period. The undersigned may establish a trading plan intended to comply with Rule 10b5-1 under the Exchange Act, provided that, the plan does not provide for or permit any sale or other transfer of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock during the 90-day restricted period, any required filing related to such plan shall state that such sales or other transfers during the 90-day restricted period are prohibited and no other public announcement shall be required or shall be voluntarily made during such 90-day restricted period. 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.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this letter agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if the Purchase Agreement does not become effective, or if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, the undersigned shall be released from all obligations under this letter agreement. The undersigned understands that the Representatives are entering into the Purchase Agreement and proceeding with the Offering in reliance upon this letter agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to the Purchase Agreement, the terms of which are subject to negotiation between the Company and the Representatives.

This letter agreement and any claim, controversy or dispute arising under or related to this letter agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof..
