ARTICLE 1

DEFINITIONS

Section 1.01 Definitions . For all purposes of this Supplemental Indenture, except as otherwise expressly provided or unless the context otherwise requires, (i) references to any Article, Section or subdivision thereof are references to an Article, Section or other subdivision of this Supplemental Indenture and (ii) capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture.

ARTICLE 2

TERMS AND CONDITIONS OF THE SENIOR

NOTES AND THE RELATED GUARANTEES

Section 2.01 Designation, Principal Amount and Terms. There is hereby authorized and established, pursuant to Section 301 of the Indenture, a series of Securities designated as the “5.100% Senior Notes due 2034,” with such series guaranteed by the Guarantors pursuant to the Indenture.

(a) The 5.100% Senior Notes due 2034 and the related Guarantees shall be executed, authenticated and delivered in accordance with the provisions of, and shall in all respects be subject to, the terms, conditions and covenants of the Indenture and this Supplemental Indenture (including the form of Security set forth in Exhibit A-1 hereto and the form of Guarantee set forth in Exhibit A-2 hereto). Subject to Section 203 hereof, the aggregate principal amount of the 5.100% Senior Notes due 2034 which may initially be authenticated and delivered under this Supplemental Indenture shall not, except as permitted by the provisions of the Indenture, exceed $500,000,000.

Section 2.02 Optional Redemption. Prior to March 13, 2034 (three months prior to the maturity date of the Senior Notes) (the “Par Call Date”), the Company may redeem the Senior Notes at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(A) the (a) sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Senior Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date, and

(B) 100% of the principal amount of the Senior Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Company may redeem the Senior Notes, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Senior Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

4

If on the third Business Day preceding the Redemption Date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

The Company will send by electronic delivery or mail otherwise in accordance with the procedures of the U.S. Depositary notice of any redemption at least 10 days but not more than 60 days before the Redemption Date to each Holder of the Senior Notes to be redeemed. Once the notice of redemption is sent, the Senior Notes called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest to the Redemption Date, subject to any conditions precedent specified in such notice. If such redemption is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the Business Day immediately preceding the relevant Redemption Date. The Company shall notify Holders of any such rescission as soon as practicable after we determine that such conditions precedent will not be able to be satisfied or the Company is not able or willing to waive such conditions precedent. In addition, the Company may provide in such notice that payment of the Redemption Price and performance of the Company’s obligations with respect to such redemption may be performed by another Person.

In the case of a partial redemption of the Senior Notes, selection of the Senior Notes for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No Senior Notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the Holder of the note upon surrender for cancellation of the original note. For so long as the Senior Notes are held by the U.S. Depositary (or another depositary), the redemption of the Senior Notes shall be done in accordance with the policies and procedures of the depositary. The Senior Notes will not be entitled to the benefit of any mandatory redemption or sinking fund.

5

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Senior Notes or portions thereof called for redemption.

Section 2.03 Mandatory Redemption; Offers to Purchase; Open Market Purchases. The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Senior Notes. In addition, other than as required in the case of a Change of Control Triggering Event, the Company shall not be required to offer to repurchase or redeem or otherwise modify the terms of any of the Senior Notes upon a change in control of, or other events involving, Trane Parent or any of its subsidiaries which may adversely affect the creditworthiness of the Senior Notes. The Company and its affiliates may, at any time and from time to time, acquire the Senior Notes by means other than a redemption, whether pursuant to a tender offer, purchases in the open market, in privately negotiated transactions or otherwise.

Section 2.04 Additional Issuances. The Company may, at any time, without the consent of the Holders of the Senior Notes, issue additional Senior Notes having the same ranking and the same interest rate, maturity and other terms as any of the existing Senior Notes. Any additional Senior Notes having such similar terms, together with the existing Senior Notes, may constitute a single series of Senior Notes under the Indenture and this Supplemental Indenture; provided, however, if the additional Senior Notes are not fungible with the existing Senior Notes of such series for U.S. federal income tax purposes, such additional Senior Notes shall have a different CUSIP number. No additional Senior Notes may be issued if an Event of Default under the Indenture has occurred and is continuing with respect to the Senior Notes.

Section 2.05 Special Tax Redemption. Any Payor (as defined below) may elect to redeem the outstanding Senior Notes, in whole but not in part, at any time, upon not less than 30 nor more than 60 days’ prior written notice delivered electronically or mailed by first-class mail to the registered address of each Holder of the Senior Notes or otherwise in accordance with the procedures of the U.S. Depositary, at a Redemption Price equal to 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but not including, the date fixed for redemption (a “Tax Redemption Date”), and Additional Amounts (as defined below), if any, then due or becoming due on the Tax Redemption Date in the event (i) such Payor is, has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Senior Notes, any Additional Amounts or indemnification payments (other than in respect of documentary taxes) as a result of (A) a change or amendment in the laws or treaties (including any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction; or (B) any change or amendment in the application, administration or interpretation of such laws, treaties, regulations or rulings (including pursuant to a holding, judgment or order by a court of competent jurisdiction); which change or amendment, in either case, is announced or becomes effective after the date hereof (or, if the applicable Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction on a later date, after such later date) (each of the foregoing in clauses (A) and (B), a “Change in Tax Law”); and (ii) such Payor has determined in its business judgment that the obligation to pay such Additional Amounts cannot be avoided by the use of reasonable measures available to such Payor. Notwithstanding the foregoing, no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which such

6

Payor would, but for such redemption, be obligated to make such payment or withholding or later than 90 days after such Payor is first obligated to make such payment or withholding. Prior to the delivery or mailing of any notice of redemption of the Senior Notes pursuant to the foregoing, such Payor shall deliver to the Trustee (1) a certificate signed by a duly authorized officer stating that such Payor is entitled to effect the redemption and setting forth a statement of facts showing that the conditions precedent to the right of such Payor to so redeem have occurred and (2) an opinion of an independent tax counsel of recognized international standing to the effect that the circumstances referred to in clause (i) in the first sentence of this Section 205 exist, and the Trustee shall accept such certificate and such opinion as sufficient evidence of the satisfaction of the conditions precedent above, which acceptance shall then be conclusive and binding on the Holders of Senior Notes.

Section 2.06 Tax Considerations for Holders. Any Payor may request at any time from Holders of Senior Notes who are “United States persons” within the meaning of Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended (the “Code”), to provide a properly completed and duly executed U.S. Internal Revenue Service Form W-9 (or valid substitute form) and from Holders of Senior Notes who are not “United States persons” within the meaning of Section 7701(a)(30) of the Code to provide a properly completed and duly executed U.S. Internal Revenue Service Form W-8BEN, W-8ECI or W-8IMY (or valid substitute form). Any such request must be complied with by such Holder or Holders within 30 days’ of the receipt thereof, such request to be made in writing and mailed by first-class mail to the registered address of such Holder or Holders. If a form previously delivered pursuant to this Section 206 expires or becomes obsolete, or if there is a change in circumstances requiring a change in the form previously delivered, the Holder that previously delivered such form shall deliver a new, properly completed and duly executed form on or before the date that the previously delivered form expires or becomes obsolete or promptly after the change in circumstances occurs.

Section 2.07 Additional Amounts.

All payments made by the Company or any Guarantor (except Trane Global, Trane HoldCo, and Trane Company) or a successor of the Company or such Guarantor (except Trane Global, Trane HoldCo, and Trane Company) (each a “Payor”) on the Senior Notes in respect of interest, premium (if any) and principal shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes imposed or levied by or on behalf of:

7

shall at any time be required from any payments made with respect to the Senior Notes in respect of interest, premium or principal, the Payor shall pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by each beneficial owner of the Senior Notes or the Guarantee, as the case may be, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), equal the amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no such Additional Amounts shall be payable with respect to:

8

Such Additional Amounts shall also not be payable where, had the beneficial owner of the note been the Holder of the note, it would not have been entitled to payment of Additional Amounts by reason of any of clauses (1) to (9) inclusive above.

The Payor shall (i) make any required withholding or deduction and (ii) remit the full amount deducted or withheld to the Relevant Taxing Jurisdiction in accordance with applicable law. The Payor shall use all reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes and shall provide such certified copies to each Holder. The Payor shall attach to each certified copy a certificate stating (x) that the amount of withholding Taxes evidenced by the certified copy was paid in connection with payments in respect of the principal amount of Senior Notes then outstanding and (y) the amount of such withholding Taxes paid per $1,000 principal amount of the Senior Notes. Copies of such documentation shall be available for inspection during ordinary business hours at the office of the Trustee by the Holders of the Senior Notes upon request and shall be made available at the offices of the Paying Agent.

At least 30 days prior to each date on which any payment under or with respect to the Senior Notes or the Guarantee is due and payable (unless such obligation to pay Additional Amounts arises shortly before or after the 30th day prior to such date, in which case it shall be promptly thereafter), if the Payor shall be obligated to pay Additional Amounts with respect to such payment, the Payor shall deliver to the Trustee an Officers’ Certificate stating the fact that such Additional Amounts shall be payable, the amounts so payable and shall set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date. Each such Officer’s Certificate shall be relied upon until receipt of a further Officers’ Certificate addressing such matters.

If the Payor conducts business in any jurisdiction (an “Additional Taxing Jurisdiction”) other than a Relevant Taxing Jurisdiction and, as a result, is required by the law of such Additional Taxing Jurisdiction to deduct or withhold any amount on account of taxes imposed by such Additional Taxing Jurisdiction from payments under the Senior Notes or the Guarantee, as the case may be, which would not have been required to be so deducted or withheld but for such conduct of business in such Additional Taxing Jurisdiction, the Additional Amounts provision described above shall be considered to apply to such Holders or beneficial owners as if references

9

in such provision to “Taxes” included taxes imposed by way of deduction or withholding by any such Additional Taxing Jurisdiction (or any political subdivision thereof or governmental authority therein).

Wherever in the Indenture, the Senior Notes or the Guarantee there are mentioned, in any context:

such reference shall be deemed to include payment of Additional Amounts as described under this section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The Payor shall pay any present or future stamp, court or documentary taxes, or any other excise or property taxes, charges or similar levies which arise in any jurisdiction from the execution, delivery or registration of any Senior Notes or any other document or instrument referred to therein (other than a transfer of the Senior Notes), or the receipt of any payments with respect to the notes or the guarantee, excluding (i) any such taxes, charges or similar levies imposed by Luxembourg in case the notes or the guarantee (and/or any documents in connection therewith) are (a) enclosed to a compulsorily registrable deed (acte obligatoirement enregistrable) or (b) deposited with the official records of a notary (déposé au rang des minutes d’un notaire) and (ii) any such taxes, charges or similar levies imposed by any jurisdiction other than a Relevant Taxing Jurisdiction, other than those resulting from, or required to be paid in connection with, the enforcement of the Senior Notes, the Guarantee or any other such document or instrument following the occurrence of any Event of Default with respect to the Senior Notes.

The foregoing obligations shall survive any termination, defeasance or discharge of the Indenture and shall apply mutatis mutandis to any jurisdiction in which any successor to a Payor is organized or otherwise considered a resident for tax purposes or any political subdivision or governmental authority or agency thereof or therein.

Section 2.08 Offer to Redeem Upon Change of Control Triggering Event.

Upon the occurrence of a Change of Control Triggering Event, unless the Company has previously exercised its right to redeem the Senior Notes in full, each Holder of the Senior Notes shall have the right to require the Company to purchase all or a portion of such Holder’s Senior Notes pursuant to the offer described below (the “Change of Control Offer”) at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase, subject to the rights of Holders of the Senior Notes on the relevant record date to receive interest due on the relevant interest payment date.

10

Within 30 days following the date upon which the Change of Control Triggering Event occurred, or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall be required to send, by electronic delivery or first class mail or otherwise in accordance with the procedures of the U.S. Depositary, a notice to each Holder of the Senior Notes, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state:

(i) (a) if delivered or mailed following the date upon which a Change of Control Triggering Event has occurred, that a Change of Control Triggering Event has occurred and that such Holder of the Senior Notes has the right to require the Company to purchase all or a portion of such Holder’s Senior Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of the Senior Notes of record on the relevant record date to receive interest on the relevant interest payment date), or (b) if delivered or mailed prior to any Change of Control but after the public announcement of a pending Change of Control, that a Change of Control is pending and, upon the occurrence of a Change of Control Triggering Event, such Holder of the Senior Notes has the right to require the Company to purchase all or a portion of such Holder’s Senior Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of the Senior Notes of record on the relevant record date to receive interest on the relevant interest payment date) and that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date;

(ii) the circumstances and relevant facts regarding such Change of Control Triggering Event;

(iii) the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is delivered or mailed, other than as may be required by law (the “Change of Control Payment Date”); and

(iv) the instructions determined by the Company, consistent with this Section, that a Holder of the Senior Notes must follow in order to have its Senior Notes purchased.

Holders of the Senior Notes electing to have Senior Notes purchased pursuant to a Change of Control Offer shall be required to surrender their Senior Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Senior Notes completed, to the Paying Agent at the address specified in the notice, or transfer their Senior Notes to the Paying Agent by book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day prior to the Change of Control Payment Date. Holders of the Senior Notes shall be entitled to withdraw their election if the Paying Agent receives not later than one Business Day prior to the purchase date a telegram, telex facsimile transmission or letter setting forth the name of the Holder of the Senior Notes and a statement that such Holder is withdrawing its election to have such Senior Notes purchased.

11

On the Change of Control Payment Date, the Company shall, to the extent lawful:

The Paying Agent shall promptly mail or transfer to each Holder of Senior Notes properly tendered the purchase price for the Senior Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book-entry) to each such Holder new Senior Notes equal in principal amount to any unpurchased portion of any Senior Notes surrendered; provided that each new Senior Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. A Senior Note shall be deemed to have been accepted for purchase at the time the Paying Agent mails or delivers payment therefor to the Surrendering Holder.

The Company shall not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements in this Section 208 for such an offer made by the Company and such third party purchases all Senior Notes properly tendered and not withdrawn under its offer.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of the Senior Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Senior Notes, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Senior Notes by virtue of such conflict.

Each of the Company and Guarantors shall use reasonable best efforts to ensure that at all times at least two Rating Agencies are providing a rating for the Senior Notes.

For purposes of the Change of Control Offer provisions of the Senior Notes, the following terms shall be applicable:

“Below Investment Grade Rating Event” means, with respect to the Senior Notes, such notes cease to be rated Investment Grade by at least two of the three Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by Trane Parent of any Change of Control (or pending Change of Control) and

12

ending 60 days following the consummation of such Change of Control (which Trigger Period shall be extended if the rating of the Senior Notes is under publicly announced consideration for possible downgrade by any Rating Agency on such 60th day, such extension to last with respect to each Rating Agency until the date on which such Rating Agency considering such possible downgrade either (x) rates the Senior Notes below Investment Grade or (y) publicly announces that it is no longer considering the Senior Notes for possible downgrade; provided, that no such extension shall occur if on such 60th day the Senior Notes are rated Investment Grade not subject to review for possible downgrade by any Rating Agency).

“Change of Control” means the occurrence of any one of the following:

1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of Trane Parent and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d) and Section 14(d) of the Exchange Act) other than to Trane Parent or one of its subsidiaries;

2) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d) and Section 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of Trane Parent, or other Voting Stock into which the Voting Stock of Trane Parent is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares;

3) the first day on which the majority of the members of the board of directors of Trane Parent cease to be Continuing Directors;

4) Trane Parent consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, Trane Parent, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of Trane Parent or such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Voting Stock of Trane Parent outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person immediately after giving effect to such transaction;

5) the adoption of a plan relating to the liquidation or dissolution of Trane Parent; or

6) the failure of Trane Parent to own, directly or indirectly, at least 51% of the Voting Stock of the Company.

Notwithstanding the foregoing, a transaction shall not be deemed to involve a Change of Control under clause (2) above if (i) Trane Parent becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii) the shares of the Voting Stock of Trane Parent

13

outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of such holding company immediately after giving effect to such transaction.

“Change of Control Triggering Event” means, with respect to the Senior Notes, the occurrence of both a Change of Control and a Below Investment Grade Rating Event with respect to the Senior Notes. Notwithstanding the foregoing, no Change of Control Triggering Event shall be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Continuing Director” means, as of any date of determination, any member of the board of directors of Trane Parent who: (1) was a member of such board of directors on the date of the issuance of the Senior Notes; or (2) was nominated for election or elected to such board of directors with the approval of a majority of the Continuing Directors who were members of such board of directors at the time of such nomination or election.

“Fitch” means Fitch Inc., a subsidiary of Fimalac, S.A., and its successors.

“Investment Grade” means (1) a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s); (2) a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P); and (3) a rating of BBB- or better by Fitch (or its equivalent under any successor rating category of Fitch).

“Moody’s” means Moody’s Investors Services, Inc., a subsidiary of Moody’s Corporation, and its successors.

Exhibit A-1 - 2

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed and delivered on the date first written above.

Exhibit A-1 - 3

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Exhibit A-1 - 4

(Reverse of Note)

TRANE TECHNOLOGIES FINANCING LIMITED

5.100% Senior Notes due 2034

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of June 13, 2024, as supplemented (herein called the “Indenture”), among the Company, Trane Technologies plc, Trane Technologies Global Holding II Company Limited, Trane Technologies Lux International Holding Company S.à r.l., Trane Technologies Irish Holdings Unlimited Company, Trane Technologies HoldCo Inc., and Trane Technologies Company LLC (herein called the “Guarantors”, which term includes any successor guarantor under the Indenture) and Computershare Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to [   ].

Prior to the Par Call Date, the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(A) the (a) sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date, and

(B) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

The Company will send by electronic delivery or mail otherwise in accordance with the procedures of the U.S. Depositary notice of any redemption at least 10 days but not more than 60 days before the Redemption Date to each Holder of the Securities to be redeemed. Once the notice of redemption is sent, the Securities called for redemption will become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest to the Redemption Date, subject to any conditions precedent specified in such notice. If such redemption is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the Business Day immediately preceding

Exhibit A-1 - 5

the relevant Redemption Date. The Company shall notify Holders of any such rescission as soon as practicable after we determine that such conditions precedent will not be able to be satisfied or the Company is not able or willing to waive such conditions precedent. In addition, the Company may provide in such notice that payment of the Redemption Price and performance of the Company’s obligations with respect to such redemption may be performed by another Person.

In the case of a partial redemption of the Securities, selection of the Securities for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No Securities of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the Holder of the note upon surrender for cancellation of the original note. For so long as the Securities are held by the U.S. Depositary (or another depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the depositary. The Securities will not be entitled to the benefit of any mandatory redemption or sinking fund.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Securities or portions thereof called for redemption.

In the event of redemption of this Security in part only, a new Security or Securities of this series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

Any Payor may elect to redeem the outstanding Securities, in whole but not in part, at any time, upon not less than 30 nor more than 60 days’ prior written notice delivered electronically or mailed by first-class mail to the registered address of each Holder of the Securities or otherwise in accordance with the procedures of the U.S. Depositary, at a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed, plus accrued and unpaid interest thereon, if any, to, but not including, the date fixed for redemption (a “Tax Redemption Date”), and Additional Amounts, if any, then due or becoming due on the Tax Redemption Date in the event (i) such Payor is, has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Securities, any Additional Amounts or indemnification payments (other than in respect of documentary taxes) as a result of (A) a change or amendment in the laws or treaties (including any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction; or (B) any change or amendment in the application, administration or interpretation of such laws, treaties, regulations or rulings (including pursuant to a holding, judgment or order by a court of competent jurisdiction); which change or amendment, in either case, is announced or becomes effective after the date hereof (or, if the applicable Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction on a later date, after such later date) (each of the foregoing in clauses (A) and (B), a “Change in Tax Law”); and (ii) the Company has determined in its business judgment that the obligation to pay such Additional Amounts cannot be avoided by the use of reasonable measures available to the Company.

Exhibit A-1 - 6

Notwithstanding the foregoing, no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which such Payor would, but for such redemption, be obligated to make such payment or withholding or later than 90 days after such Payor is first obligated to make such payment or withholding. Prior to the delivery or mailing of any notice of redemption of the Securities pursuant to the foregoing, such Payor shall deliver to the Trustee (1) a certificate signed by a duly authorized officer stating that such Payor is entitled to effect the redemption and setting forth a statement of facts showing that the conditions precedent to the right of such Payor to so redeem have occurred and (2) an opinion of an independent tax counsel of recognized international standing to the effect that the circumstances referred to in clause (i) in the first sentence of the previous paragraph exist, and the Trustee shall accept such certificate and such opinion as sufficient evidence of the satisfaction of the conditions precedent above, which acceptance shall then be conclusive and binding on the Holders of Securities.

The Company shall not be required to make any mandatory redemption or sinking fund payments with respect to the Securities. In addition, other than as required in the case of a Change of Control Triggering Event, the Company shall not be required to offer to repurchase or redeem or otherwise modify the terms of any of the Securities upon a change in control of, or other events involving, Trane Parent or any of its subsidiaries which may adversely affect the creditworthiness of the Securities. The Company and its affiliates may, at any time and from time to time, acquire the Securities by means other than a redemption, whether pursuant to a tender offer, purchases in the open market, in privately negotiated transactions or otherwise.

The Securities of this series are subject to redemption upon the occurrence of a Change of Control Triggering Event. Unless the Company has exercised its right to redeem this Security in full as described above, the Indenture provides that each Holder of the Securities of this series will have the right to require the Company to purchase all or a portion of such Holder’s Securities of this series pursuant to the offer described below (the “Change of Control Offer”) at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase, subject to the rights of Holders of Securities of this series on the relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the Change of Control Triggering Event occurred, or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to send, by electronic delivery or first class mail or otherwise in accordance with the procedures of the U.S. Depositary, a notice to each Holder of the Securities of this series, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is delivered or mailed, other than as may be required by law (the “Change of Control Payment Date”). The notice, if delivered or mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

Holders electing to have Securities purchased pursuant to a Change of Control Offer will be required to surrender their Securities, with the form below entitled “Option of Holder to Elect Purchase” completed, to the paying agent at the address specified in the notice, or transfer their Securities to the paying agent by book-entry transfer pursuant to the applicable procedures of the paying agent, prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

Exhibit A-1 - 7

On the Change of Control Payment Date, the Company will, to the extent lawful:

The paying agent will promptly mail to each Holder of properly tendered Securities the purchase price for the Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each such Holder new Securities equal in principal amount to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

The Company will not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third-party purchases all properly tendered Securities of this series not withdrawn under its offer.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of the Securities of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Securities of this series, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the Securities of this series by virtue of such conflict.

For purposes of the Change of Control Offer provisions of the Securities, the following terms will be applicable:

“Below Investment Grade Rating Event” means the Securities of this series cease to be rated Investment Grade by at least two of the three Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by Trane Parent of any Change of Control (or pending Change of Control) and ending 60 days following the consummation of such Change of Control (which Trigger Period will be extended if the rating of the Securities is under publicly announced consideration for possible downgrade by any Rating Agency on such 60th day, such extension to last with respect to each Rating Agency until the date on which such Rating Agency considering such

Exhibit A-1 - 8

possible downgrade either (x) rates the Securities below Investment Grade or (y) publicly announces that it is no longer considering the Securities for possible downgrade; provided, that no such extension will occur if on such 60th day the Securities are rated Investment Grade not subject to review for possible downgrade by any Rating Agency).

Exhibit A-1 - 9

“Change of Control” means the occurrence of any one of the following:

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control under clause (2) above if (i) Trane Parent becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii) the shares of the Voting Stock of Trane Parent outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of such holding company immediately after giving effect to such transaction.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“S&P” means S&P Global Ratings, a division of S&P Global, Inc., and its successors.

“Voting Stock” of any specified person as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Guarantors and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company, the Guarantors and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding of all series to be affected, on behalf of the Holders of all Securities of such series, to waive compliance by the Company and/or the Guarantors with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

Exhibit A-1 - 11

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest, if any, on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
