ARTICLE 1

INTERPRETATION

Section 1.1 To Be Read With Trust Indenture

This First Supplemental Indenture is a Supplemental Indenture within the meaning of the Trust Indenture. The Trust Indenture and this First Supplemental Indenture shall be read together and shall have effect so far as practicable as though all the provisions of both indentures were contained in one instrument.

Section 1.2 First Supplemental Indenture

The terms “this First Supplemental Indenture”, “this indenture”, “herein”, “hereof”, “hereby”, “hereunder”, and similar expressions, unless the context otherwise specifies or requires, refer to the Trust Indenture as amended and supplemented by this First Supplemental Indenture and not to any particular Article, section, subsection or clause or other portion thereof, and include every instrument supplemental or ancillary to this First

Supplemental Indenture. For clarity and avoidance of doubt, the provisions of this First Supplemental Indenture shall only be applicable to the Series 1 Notes issued hereunder and shall not be applicable to any other series of Notes hereafter issued.

Section 1.3 Definitions

All terms which are defined in the Trust Indenture and used but not defined in this First Supplemental Indenture shall have the meanings ascribed to them in the Trust Indenture, as such meanings may be amended by this First Supplemental Indenture. In the event of any inconsistency between the terms in the Trust Indenture and this First Supplemental Indenture, the terms in this First Supplemental Indenture shall prevail. Subject to the foregoing, in this First Supplemental Indenture and in the Series 1 Notes the following terms have the following meanings:

“Canada Yield Price” means a price equal to the price of the Series 1 Notes calculated to provide a yield to maturity (calculated from the redemption date), compounded semi-annually and calculated in accordance with generally accepted Canadian financial practice, equal to the Government of Canada Yield calculated at 10:00 a.m. (Toronto time) on the Business Day preceding the day on which the Issuer gives notice of redemption pursuant to Section 5.4 of the Trust Indenture, plus 0.30%;

“Change of Control” shall mean the occurrence of any one of the following: (a) the direct or indirect sale, transfer, conveyance, lease or other disposition (other than by way of consolidation, amalgamation or merger), in one or a series of related transactions, of all or substantially all of the property and assets of the Issuer and its Subsidiaries, taken as a whole, to any Person or group of Persons acting jointly or in concert for purposes of such transaction (other than to the Issuer or its Subsidiaries or other related entity (not involving a Third Party) formed for the purpose of completing a corporate reorganization); or (b) the consummation of any transaction including any consolidation, amalgamation, merger or issue of voting shares the result of which is that any Person or group of Persons acting jointly or in concert for purposes of such transaction (other than the Issuer and its Subsidiaries) becomes the beneficial owner, directly or indirectly, of more than 50% of the voting shares of the Issuer, measured by voting power rather than number of shares (but shall not include the creation of a holding company or similar transaction that does not involve a change in the beneficial ownership of the Issuer);

“Change of Control Offer” has the meaning set out in Section 3.1(a);

“Change of Control Payment” has the meaning set out in Section 3.1(a);

“Change of Control Payment Date” has the meaning set out in Section 3.1(b);

“Change of Control Triggering Event” shall mean the occurrence of both a Change of Control and a Rating Event;

“Government of Canada Yield” on any date means the yield to maturity on such date, compounded semi-annually and calculated in accordance with generally

- 2 -

accepted Canadian financial practice, which a non-callable Government of Canada bond would carry if issued in dollars in Canada, at 100% of its principal amount on such date with a term to maturity equal to, or if no Government of Canada bond having an equal term to maturity exists, as close as possible to, the remaining term to maturity of, in the case of the Series 1 Notes, the Series 1 Notes, such yield to maturity being the average of the yields provided by two Canadian investment dealers specified by the Issuer;

“Investment Grade Rating” shall mean a rating equal to or higher than BBB (low) (or the equivalent of any successor rating category of DBRS) by DBRS, or the equivalent investment grade credit rating from any other Specified Rating Agency;

“Rating Event” shall mean the rating on the Series 1 Notes is lowered to below an Investment Grade Rating by the Specified Rating Agency on any day within the 60-day period (which 60-day period will be extended so long as the rating of the Series 1 Notes is under publicly announced consideration for a possible downgrade by the Specified Rating Agency, but only to the extent that, and for so long as, a Change of Control Triggering Event would result if such downgrade were to occur) after the earlier of (a) the occurrence of a Change of Control and (b) public notice of the occurrence of a Change of Control or of the Issuer’s intention or agreement to effect a Change of Control;

“Redemption Price” has the meaning set out in Section 2.8(a);

“Series 1 Notes” means the notes referred to in Section 2.1 hereof;

“Specified Rating Agency” shall mean DBRS, as long as such entity has not ceased to rate the Series 1 Notes or failed to make a rating of the Series 1 Notes publicly available for reasons outside of the Issuer’s control; provided that if DBRS ceases to rate the Series 1 Notes or fails to make a rating of the Series 1 Notes publicly available for reasons outside of the Issuer’s control, the Issuer may select any other “approved rating organization” within the meaning of National Instrument 41-101 of the Canadian Securities Administrators as a replacement agency; and

“Trust Indenture” has the meaning set out in the Recital A.

TIM HORTONS INC. (the “Issuer”) for value received hereby promises to pay to the registered holder hereof on the Stated Maturity, or on such earlier date as the Principal Amount may become due in accordance with the provisions of the Trust Indenture (as defined below), on presentation and surrender of this 4.20% Senior Unsecured Note, Series 1 due June 1, 2017 (the “Series 1 Note”) at the principal office of the Trustee (as defined below), the Principal Amount in lawful money of Canada, and to pay interest on the Principal Amount, from time to time outstanding, at the Interest Rate per annum, in like money, semi-annually, in arrears, in equal instalments on the Interest Payment Dates in each year, the first such payment to be payable on the Initial Interest Payment Date and the last such payment to be payable on the date of the Stated Maturity, in an amount equal to $21.00 per $1,000 principal amount, and if the Issuer at any time defaults in the payment of any principal or interest, to pay interest on the amount in default at the same rate, in like money, at the principal office of the Trustee and semi-annually on the same dates.

This Series 1 Note is a single registered Note representing Cdn.$200,000,000 of the 4.20% Senior Unsecured Notes, Series 1 due June 1, 2017 of the Issuer issued under a trust indenture (the “Master Indenture”) dated June 1, 2010 made between the Issuer and BNY Trust Company of Canada (the “Trustee”), as supplemented by a First Supplemental Indenture dated June 1, 2010 made between the Issuer and the Trustee (the “First Supplemental Indenture” and together with the Master Indenture, the “Trust Indenture”).
