Indenture and the Notes

On November 6, 2017, the Company issued $258.75 million aggregate principal amount of the Notes, pursuant to an Indenture, dated as of such date (the “Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The Notes will bear interest at the annual rate of 1.00%, payable on May 15 and November 15 of each year, beginning on May 15, 2018, and will mature on November 15, 2024 unless earlier converted or repurchased. The Notes may be settled in cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election (subject to, and in accordance with, the settlement provisions of the Indenture). The initial conversion rate for the Notes is 17.0285 shares of common stock (subject to adjustment as provided for in the Indenture) per $1,000 principal amount of the Notes, which is equal to an initial conversion price of approximately $58.73 per share, representing a conversion premium of approximately 35% above the closing price of the Company’s common stock of $43.50 per share on October 31, 2017. In addition, following certain corporate events that occur prior to the maturity date as described in the Indenture, the Company will pay a make-whole premium by increasing the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event in certain circumstances.

Holders of the Notes may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding August 15, 2024 only under the following circumstances:

On or after August 15, 2024 until the close of business on the second scheduled trading day immediately preceding November 15, 2024, holders may convert their Notes at the option of the holder regardless of the foregoing circumstances.

The Company may not redeem the Notes prior to the maturity date, and no sinking fund is provided for the Notes.

If the Company undergoes a fundamental change, as described in the Indenture, prior to the maturity date of the Notes, holders of the Notes will, subject to specified conditions, have the right, at their option, to require the Company to repurchase for cash all or a portion of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but not including, the “fundamental change repurchase date” (as defined in the Indenture).

The Notes are senior subordinated unsecured obligations of the Company and will rank senior in right of payment to any of the Company’s existing and future subordinated debt; equal in right of payment with the Company’s existing and future senior subordinated debt; subordinated in right of payment to the Company’s existing and future senior indebtedness, including its indebtedness under its credit agreement; effectively subordinated to the Company’s existing and future secured debt, including its indebtedness under its credit agreement, to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all secured and unsecured existing and future indebtedness (including trade payables) incurred by the Company’s subsidiaries.

The foregoing description of the Indenture and the Notes is qualified in its entirety by reference to each of the Indenture and the form of Note, which are filed as Exhibit 4.1 to this Current Report on Form 8-K and are incorporated herein by reference.

Convertible Note Hedge and Warrant Transactions

On October 31, 2017, in connection with the pricing of the Initial Notes, the Company entered into convertible note hedge transactions (the “Initial Note Hedge Transactions”) with certain of the Initial Purchasers (the “Option Counterparties”). On November 1, 2017, in connection with the Initial Purchasers’ exercise of the over-allotment option to purchase the Option Notes, the Company entered into additional convertible note hedge transactions (the “Additional Note Hedge Transactions” and, together with the Initial Note Hedge Transactions, the “Note Hedge Transactions”) with the Option Counterparties.

The Note Hedge Transactions are expected generally to reduce the potential dilution and/or offset any cash payments the Company is required to make in excess of the principal amount due, as the case may be, upon conversion of the Notes in the event that the market price of the Company’s common stock is greater than the strike price of the Note Hedge Transactions, which is initially $58.73 (subject to adjustment), corresponding to the initial conversion price of the Notes.

On October 31, 2017, the Company also entered into separate, privately negotiated warrant transactions with the Option Counterparties (the “Initial Warrant Transactions”). On November 1, 2017, the Company entered into additional privately negotiated warrant transactions (the “Additional Warrant Transactions” and, together with the Initial Warrant Transactions, the “Warrant Transactions”) with the Option Counterparties. In the Warrant Transactions, the Company sold net-share-settled warrants to the Option Counterparties initially relating to the same number of shares of the Company’s common stock initially underlying the Notes, subject to customary anti-dilution adjustments. The strike price of the warrants will initially be $71.7750 per share (subject to adjustment), which is approximately 65% above the last reported sale price of the Company’s common stock on October 31, 2017. The Warrant Transactions could have a dilutive effect to the Company’s stockholders to the extent that the market price per share of the Company’s common stock, as measured under the terms of the Warrant Transactions, exceeds the applicable strike price of the warrants.

The Company used $13.5 million of the net proceeds of the offering of the Notes to pay the cost of the Note Hedge Transactions (after such cost was partially offset by the proceeds to the Company from the sale of warrants in the Warrant Transactions).

The Note Hedge Transactions and the Warrant Transactions are separate transactions, in each case, entered into by the Company with the Option Counterparties, and are not part of the terms of the Notes and will not affect any holder’s rights under the Notes. Holders of the Notes will not have any rights with respect to the Note Hedge Transactions or the Warrant Transactions.

The foregoing description of the Note Hedge Transactions and Warrant Transactions is qualified in its entirety by reference to the confirmations for the Note Hedge Transactions, which are attached as Exhibits 10.1, 10.3, 10.5, 10.7, 10.9 and 10.11 to this Current Report on Form 8-K, and the Warrant Transactions, which are attached as Exhibits 10.2, 10.4, 10.6, 10.8, 10.10 and 10.12 to this Current Report on Form 8-K, and incorporated herein by reference.

Amended and Restated Senior Secured Credit Facility

On November 3, 2017, the Company and two of its subsidiaries, Chart Industries Luxembourg S.à r.l. and Chart Asia Investment Company Limited (the “Foreign Borrowers”) (the Company and the Foreign Borrowers, collectively the “Borrowers”) entered into a Third Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent (the “Administrative Agent”), and several other financial institutions party thereto, providing for a five-year $450 million senior secured multicurrency revolving credit facility (the “Restated Credit Facility”). The Restated Credit Facility includes an accordion feature which allows the Company, at its option, to add up to an aggregate of $225 million in principal amount of term loans or additional revolving credit commitments, subject to customary conditions. The Restated Credit Facility matures on November 3, 2022 (the “Maturity Date”).

The Restated Credit Facility amends and restates the Company’s prior senior secured revolving credit and term loan facility.

The Restated Credit Facility includes a $25 million sub-limit for the issuance of swingline loans, which are comparatively short-term loans used for working capital purposes, and a $200 million sub-limit for the issuance of letters of credit. The Revolving Credit Facility also provides for up to $100 million (U.S. equivalent) in foreign currency borrowings and up to $100 million in advances to the Foreign Borrowers.

Loans under the Restated Credit Facility will continue to bear interest at either LIBOR or the base rate, at the applicable Borrower’s election, plus a spread determined by the Company’s leverage ratio (as described below). At closing, the applicable spread for (a) LIBOR rate loans was 2.50% per annum, with possible future spreads ranging from 1.50% to 2.50% per annum, and (b) base rate loans was 1.50% per annum, with possible future spreads ranging from 0.50% to 1.50% per annum. As under its prior credit facility, in addition to interest, the Company is required to pay commitment fees on the unused portion of the Revolving Credit Facility at an initial rate of 0.375% per annum, which like the interest rate spreads, is subject to adjustment thereafter based on the Company’s leverage ratio, with possible future spreads ranging from 0.200% to 0.375% per annum.

The Company and its domestic Material Subsidiaries (as defined in the Restated Credit Facility) (subject to certain exemptions, “Guarantors”) continue to guaranty all of the Borrowers’ obligations in connection with the Restated Credit Facility and certain hedging and banking services obligations. The obligations of the Borrowers and the Guarantors under the Restated Credit Facility also continue to be secured by (i) a first priority perfected security interest in and lien on existing and future personal and material real property (subject to certain restrictions) of the Company and each Guarantor and (ii) a pledge of, and a first perfected security interest in, 100% of the equity interests of each of the Company’s existing and future material domestic subsidiaries and 65% of the equity interests of first-tier foreign subsidiaries owned by the Company and each Guarantor (subject to certain restrictions).

The Restated Credit Facility contains covenants that are customary for similar credit arrangements and generally consistent with or more favorable to the Company than those under its prior facility. These include covenants relating to financial reporting and notification, payment of indebtedness, taxes and other obligations, and compliance with applicable laws. There are also financial covenants that require the Company to (i) maintain certain liquidity at times when certain of its convertible bonds are near maturity or subject to repurchase at the option of the holders thereof, (ii) maintain an interest coverage ratio (defined as the ratio of consolidated EBITDA to consolidated interest expense for the four most recent fiscal quarters) of not less than 3.0 to 1.0, and (iii) maintain a leverage ratio (defined as the ratio of consolidated total indebtedness (less cash, cash equivalents and short term investments in excess of $20 million) to consolidated EBITDA for the four most recent fiscal quarters) of no greater than 3.75 to 1.0, with such required ratio stepping down over several quarters until it reaches 3.25 to 1.0 for each

period ending on or after June 30, 2019. Upon notification to the lenders, however, the required leverage ratio can be relaxed to 3.75 to 1.0 for a one-year period on up to two occasions (separated by at least two fiscal quarters) in connection with certain acquisitions or plant expansions costing more than $100 million. The Restated Credit Facility also imposes certain customary limitations and requirements on the Company with respect to, among other things, the incurrence of indebtedness and liens, the making of investments, the payment of dividends or making of other restricted payments, mergers, acquisitions and dispositions of assets, and transactions with affiliates.

The Borrowers’ failure to comply with the foregoing covenants, including compliance with the financial ratios and the minimum liquidity requirement, will constitute an event of default (subject, in the case of certain such covenants, to applicable notice and/or grace or cure periods) under the Restated Credit Facility. Other events of default under the Restated Credit Facility include the failure to timely pay principal, interest, fees or other amounts due and owing (subject to applicable grace periods), the occurrence of a change of control, certain breaches or defaults under material indebtedness, the failure to pay or discharge certain material judgments, the occurrence of certain bankruptcy or insolvency events, and the breach of representations or warranties in any material respect. Events of default under the Restated Credit Facility are consistent with or more favorable to the Company than those under its prior facility. The occurrence and continuance of an event of default could result in, among other things, amounts owing under the Restated Credit Facility being accelerated and the Revolving Credit Facility being terminated.

The foregoing description of the Restated Credit Facility is not complete and is qualified in its entirety by reference to the Restated Credit Facility, which is filed as Exhibit 10.13 to this Current Report on Form 8-K and is incorporated by reference.
