THIS SUPPLEMENTAL TRUST INDENTURE made as of the 2 nd day of June, 2011. BETWEEN: KILLAM PROPERTIES INC., a corporation incorporated under the laws of Canada (hereinafter called the "Corporation") AND WITNESSETH THAT: COMPUTERSHARE TRUST COMPANY OF CANADA, a trust company existing under the laws of Canada (hereinafter called the "Trustee") WHEREAS the Corporation has entered into a trust indenture (as amended, supplemented or restated from time to time), dated as of November 30, 2010 between the Corporation and the Trustee (the "Trust Indenture"), which provides for the issuance of one or more series of unsecured debt securities of the Corporation by way of supplemental indentures; AND WHEREAS this supplemental trust indenture (the "Supplemental Indenture") is entered into for the purpose of providing for the issue of $46,000,000 aggregate principal amount of Debentures designated as "5.45% Convertible Unsecured Subordinated Debentures" under the Trust Indenture and establishing the terms, provisions and conditions of such Debentures (the "Series 2011-1 Debentures"); NOW THEREFORE it is hereby covenanted, agreed and declared as follows: 1.1 Supplemental Indenture ARTICLE 1 INTERPRETATION This Supplemental Indenture is a "supplemental indenture" within the meaning of the Trust Indenture. The Trust Indenture and this Supplemental Indenture will be read together and have effect so far as practicable as though all of the provisions of both indentures were contained in one instrument. If any provisions of the Trust Indenture are inconsistent with the express provisions hereof, the provisions of the Trust Indenture will be, solely in respect of the Series 2011-1 Debentures, amended, varied, supplemented, modified, restated or replaced so as to be consistent with this Supplemental Indenture. The provisions of this Supplemental Indenture are applicable only in respect of the Series 2011-1 Debentures and not the Debentures of any other series. 1.2 Definitions All terms used but not defined in this Supplemental Indenture have the meanings ascribed to them in the Trust Indenture, as such meanings may be amended by this Supplemental Indenture. In the

-2- event of any inconsistency between the terms in the Trust Indenture and this Supplemental Indenture, the terms in this Supplemental Indenture prevail. Subject to the foregoing, in this Supplemental Indenture and in the Series 2011-1 Debentures, the following terms have the following meanings: "90% Redemption Right" has the meaning ascribed thereto in Subsection 2.2(i)(ii); "CDS" means CDS Clearing and Depository Services Inc., and its successors and assigns; "Change of Control Notice" has the meaning ascribed thereto in Subsection 2.2(i); "Change of Control Redemption" has the meaning ascribed thereto in Subsection 2.2(i); "Corporation" means Killam Properties Inc. and includes any successor to or of the Corporation which shall have complied with the provisions of Article 11 of the Trust Indenture. "Debentureholder" means a holder of Series 2011-1 Debentures; "Maturity Notice" has the meaning ascribed thereto in Subsection 2.2(f); "Offer" has the meaning ascribed thereto in Subsection 2.2(i); "Offer Price" has the meaning ascribed thereto in Subsection 2.2(i); "Series 2011-1 Debentures" has the meaning ascribed thereto in the recitals and as described in Section 2.2; and "Time of Expiry" has the meaning ascribed thereto in Subsection 2.2(e); 1.3 References to Sections, Articles and Schedules Unless otherwise provided, all references herein to Sections, Articles or Schedules are references to Sections, Articles and Schedules of or to this Supplemental Indenture. 2.1 Creation and Designation ARTICLE 2 THE SERIES 2011-1 DEBENTURES The Corporation is authorized to issue under this Supplemental Indenture a series of Debentures designated "5.45% Convertible Unsecured Subordinated Debentures due June 30, 2018", which will have the terms set out herein and in accordance with the Trust Indenture. 2.2 Terms of Series 2011-1 Debentures (a) The Series 2011-1 Debentures authorized for issue immediately are limited to an aggregate principal amount of $46,000,000.

-3- (b) The Series 2011-1 Debentures shall be dated as of June 2, 2011, shall mature on June 30, 2018 and shall bear interest from the date of issue at the rate of 5.45% per annum, payable in equal semi-annual payments on June 30 and December 31 in each year, except the first payment will include accrued and unpaid interest for the period from the date of this Supplemental Indenture to, but excluding, December 31, 2011 and the last such payment to fall due on June 30, 2018, payable after as well as before maturity and after as well as before default, with interest on amounts in default at the same rate, compounded semi-annually. (c) (d) (e) The Series 2011-1 Debentures will be redeemable by the Corporation in accordance with the terms of Article 4 of the Trust Indenture, provided that the Series 2011-1 Debentures will not be redeemable on or before June 30, 2014, except in the event of the satisfaction of certain conditions after a Change of Control has occurred as outlined in Subsection 2.2(i). After June 30, 2014 and on or prior to June 30, 2016, the Series 2011-1 Debentures may be redeemed in whole at any time or in part from time to time at the option of the Corporation on not more than 60 days' and not less than 30 days' prior written notice as provided for in section 4.3 of the Trust Indenture at a price equal to their principal amount including accrued and unpaid interest provided that the Current Market Price preceding the date upon which the notice for redemption is given is not less than 125% of the Conversion Price and the Corporation shall have provided to the Trustee an Officer's Certificate confirming such Current Market Price. Subsequent to June 30, 2016 and prior to June 30, 2018, the Series 2011-1 Debentures may be redeemed by the Corporation in whole at any time or in part from time to time at the option of the Corporation on not more than 60 days' and not less than 30 days' prior written notice as provided for in section 4.3 of the Trust Indenture and, in such case, the Redemption Price for the Series 2011-1 Debentures will be a price equal to their principal amount including accrued and unpaid interest. The Redemption Notice for the Series 2011-1 Debentures shall be in the form of Schedule "B". The Series 2011-1 Debentures will be subordinated to the Senior Indebtedness of the Corporation in accordance with the provisions of Article 5 of the Trust Indenture; provided, however, that nothing contained in this Supplemental Indenture shall in any way or manner restrict the Corporation from incurring, directly or indirectly, any additional indebtedness. Upon and subject to the provisions and conditions of Article 6 of the Trust Indenture, the holder of each Series 2011-1 Debenture shall have the right, at such holder's option, at any time prior to 5:00 p.m. (Halifax time) on the earlier of June 30, 2018 and the Business Day immediately preceding the date specified by the Corporation for redemption of the Series 2011-1 Debentures by notice to the holders of Series 2011-1 Debentures in accordance with Subsection 2.2(c) above and section 4.3 of the Trust Indenture (the earlier of which will be the "Time of Expiry" for the purposes of Article 6 of the Trust Indenture in respect of the Series 2011-1 Debentures), to convert the whole or, in the case of a Series 2011-1 Debenture of a denomination in excess of $1,000, any part which is $1,000 or an integral multiple thereof, of the principal amount of such Series 2011-1 Debenture into Common Shares at the Conversion Price in effect on the Date of Conversion (as defined in subsection 6.3(b) of the Trust Indenture). Notwithstanding the foregoing, no Series 2011-1 Debenture may be converted during the five business days preceding June 30 and December 31 in each year, as the registers of the Trustee will be closed during such periods.

-4- The Conversion Price in effect on the date hereof for each Common Share to be issued upon the conversion of Series 2011-1 Debentures shall be equal to $14.60 such that approximately 68.4932 Common Shares shall be issued for each $1,000 principal amount of Series 2011-1 Debentures so converted. Holders converting their Series 2011-1 Debentures shall be entitled to receive in cash, in addition to the applicable number of Common Shares, accrued and unpaid interest in respect thereof for the period from the last Interest Payment Date to and including the last record date set by the Corporation occurring prior to the date of conversion for determining the holders of Common Shares entitled to receive dividends on the Common Shares. In the event the Corporation has suspended regular dividends, then a Debentureholder, in addition to the number of Common Shares to be received on conversion of the Series 2011-1 Debentures, will be entitled to receive accrued and unpaid interest for the period from the last Interest Payment Date prior to the date of conversion to the date of conversion. The Conversion Price applicable to and the Common Shares, securities or other property receivable on the conversion of the Series 2011-1 Debentures is subject to adjustment pursuant to the provisions of section 6.4 of the Trust Indenture. Notwithstanding the foregoing, if holders of Series 2011-1 Debentures would otherwise be entitled to receive, upon conversion of the Series 2011-1 Debentures, any property (including cash) or securities that would not constitute "prescribed securities" for the purposes of clause 212(1)(b)(vii)(E) of the Tax Act as it applied on December 31, 2007 ("ineligible consideration"), such holders shall not be entitled to receive such ineligible consideration but the Corporation or the successor or acquirer, as the case may be, shall have the right (at the sole option of the Corporation or the successor or acquirer, as the case may be) to deliver either such ineligible consideration or "prescribed securities" for the purposes of clause 212(1)(b)(vii)(E) of the Tax Act as it applied on December 31, 2007 with a market value (as conclusively determined by the directors of the Corporation) equal to the market value of such ineligible consideration. (f) (g) On redemption or on maturity of the Series 2011-1 Debentures, the Corporation may, at its option and subject to the provisions of section 4.6 and section 4.10 of the Trust Indenture as applicable, and subject to regulatory approval, if required, elect to satisfy its obligation to pay the principal amount of the Series 2011-1 Debentures, in whole or in part, by issuing and delivering to the holders of Series 2011-1 Debentures Freely Tradeable Common Shares. If the Corporation elects to exercise such option, it shall deliver a Redemption Notice or a maturity notice (the "Maturity Notice"), as the case may be, to the holders of the Series 2011-1 Debentures in the form of Schedule B or Schedule C, as applicable. The Series 2011-1 Debentures shall be issued as one or more Global Debentures in denominations of $1,000 and integral multiples of $1,000 and the Trustee is hereby appointed as registrar and transfer agent for the Series 2011-1 Debentures. Each Series 2011-1 Debenture and the certificate of the Trustee endorsed thereon shall be issued in substantially the form set out in Schedule A, with such insertions, omissions, substitutions or other variations as shall be required or permitted by this Supplemental Indenture and may have imprinted or otherwise reproduced thereon such legend or legends or endorsements, not inconsistent with the provisions of this Supplemental Indenture, as may be required to comply with any law or with any rules or regulations pursuant thereto or with any rules or regulations of any securities exchange or securities regulatory authority or to conform with general usage, all as may be determined by the

-5- directors or officers of the Corporation executing such Series 2011-1 Debentures in accordance with section 2.7 of the Trust Indenture, as conclusively evidenced by their execution of a Series 2011-1 Debenture. Each Series 2011-1 Debenture shall additionally bear such distinguishing letters and numbers as the Trustee shall approve. Notwithstanding the foregoing, a Series 2011-1 Debenture may be in such other form or forms as may, from time to time, be approved by a resolution of the directors or as specified in an Officer's Certificate. The Series 2011-1 Debentures may be engraved, lithographed, printed, mimeographed or typewritten or partly in one form and partly in another. The Series 2011-1 Debentures shall be issued as Global Debentures and the Depositary or Depositaries for such Global Debentures in whose name the Global Debentures will be registered (and the Global Debentures may be registered in the name of a nominee of the Depositary), and any circumstances other than or in addition to those set forth in section 3.2 of the Trust Indenture in which any such Global Debenture may be exchanged for Series 2011-1 Debentures in registered form that are not Global Debentures, or transferred-to and registered in the name of a person other than the Depositary for such Global Debentures or a nominee thereof, shall be determined by the Corporation at the time of issue. (h) (i) Upon and subject to the provisions and conditions of Article 10 of the Trust Indenture, the Corporation may elect, from time to time, to satisfy its Interest Obligation, in whole or in part, on the Series 2011-1 Debentures on any Interest Payment Date by delivering Common Shares to the Trustee. Within 30 days following the occurrence of a Change of Control, and subject to the provisions and conditions of this Subsection 2.2(i), the Corporation shall be obligated to offer to purchase the then outstanding Series 2011-1 Debentures ("Change of Control Redemption"). The terms and conditions of such obligation are set forth below: (i) Within 30 days following the occurrence of a Change of Control, the Corporation shall deliver to the Trustee, and the Trustee shall promptly deliver to the holders of the Series 2011-1 Debentures a notice stating that there has been a Change of Control and specifying the circumstances surrounding such event (a "Change of Control Notice") together with an offer in writing (the "Offer") to purchase all then outstanding Series 2011-1 Debentures made in accordance with the requirements of Applicable Securities Legislation at a price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, on such Series 2011-1 Debentures up to, but excluding, the date of acquisition of the Debentures by the Corporation or a related party of such Debentures (the "Offer Price") which Offer shall, unless otherwise provided under Applicable Securities Legislation, be open for acceptance thereof for a period of not less than 35 days and not more than 60 days and shall provide for payment to all Debentureholders who accept the Offer not later than the 60th day after the making of the Offer. The Change of Control Notice shall specify (i) the provision of the Trust Indenture pursuant to which the Offer is being made and that all Series 2011-1 Debentures validly tendered will be accepted for payment; (ii) the Offer Price and date of acquisition by the Corporation; (iii) that any Series 2011-1 Debenture not tendered will continue to accrue interest in accordance with its terms; (iv) that any Series 2011-1 Debenture accepted for payment pursuant to the Offer shall cease to accrue interest from and after the date of acquisition by the

-6- Corporation unless the Corporation defaults in the payment of the Offer Price; (v) that any Debentureholder electing to have a Series 2011-1 Debenture purchased pursuant to the Offer will be required to surrender the Series 2011-1 Debenture to the Trustee at the address specified in the Change of Control Notice prior to the close of business on the Business Day immediately preceding the date of acquisition by the Corporation or, in the case of the Global Debenture, that the purchase will take place in such manner as may be agreed upon by the Depository, the Trustee and the Corporation and specified in the Offer; and (vi) that a Debentureholder will be entitled to withdraw his election if the Trustee receives, not later than the close of business on the third Business Day immediately preceding the date of acquisition by the Corporation, a facsimile transmission or letter setting forth the name of such Debentureholder, the principal amount of Debentures delivered for purchase and a statement that such Debentureholder is withdrawing his election to have such Series 2011-1 Debentures purchased. (ii) (iii) If 90% or more in aggregate principal amount of Series 2011-1 Debentures outstanding on the date the Corporation provides the Change of Control Notice and the Offer to holders of the Series 2011-1 Debentures have been tendered for purchase pursuant to the Offer on the expiration thereof, the Corporation has the right and obligation upon written notice provided to the Trustee within 10 days following the expiration of the Offer, to redeem and shall redeem all the Series 2011-1 Debentures remaining outstanding on the expiration of the Offer at the Offer Price (the "90% Redemption Right"). Upon receipt of notice that the Corporation has exercised or is exercising the 90% Redemption Right and is acquiring the remaining Series 2011-1 Debentures, the Trustee shall promptly provide written notice to each Debentureholder that did not previously accept the Offer that: (A) (B) (C) the Corporation has exercised the 90% Redemption Right and is purchasing all outstanding Series 2011-1 Debentures effective on the expiry of the Offer at the Offer Price, and shall include a calculation of the amount payable to such holder as payment of the Offer Price; each such holder must transfer his Series 2011-1 Debentures to the Trustee on the same terms as those holders that accepted the Offer and must send its Series 2011-1 Debentures, duly endorsed for transfer, to the Trustee within 10 days after the sending of such notice; and the rights of such holder under the terms of the Series 2011-1 Debentures and this Supplemental Indenture cease to be effective as of the date of expiry of the Offer provided the Corporation has, on or before the time of notifying the Trustee of the exercise of the 90% Redemption Right, paid the aggregate Offer Price to, or to the order of, the Trustee and thereafter the Series 2011-1 Debentures shall not be considered to be outstanding and each holder thereof shall not have any right except to receive such holder's Offer Price upon surrender and delivery of such holder's Series 2011-1 Debentures in accordance with the Trust Indenture.

-7- The form of notice to be provided to each Debentureholder that did not previously accept the Offer shall be prepared by the Corporation or counsel to the Corporation, and the Trustee shall not be responsible for calculating any amount payable to such holders. (iv) (v) (vi) (vii) The Corporation shall, on or before 11:00 a.m. (Halifax time) on the date of the expiry of the Offer, deposit with the Trustee or any paying agent to the order of the Trustee by electronic transfer or certified cheque, such sums of money as may be sufficient to pay the aggregate Offer Price of the Series 2011-1 Debentures to be purchased or redeemed by the Corporation on the expiry of the Offer. The Corporation shall also deposit with the Trustee a sum of money sufficient to pay any charges or expenses which may be incurred by the Trustee in connection with such purchase and/or redemption, as the case may be. Every such deposit shall be irrevocable. From the sums so deposited, the Trustee shall pay or cause to be paid to the holders of such Series 2011-1 Debentures, the Offer Price and accrued and unpaid interest, if any, to which they are entitled on the Corporation's purchase or redemption. For greater certainty, the Corporation shall not be permitted to satisfy the Offer Price or accrued and unpaid interest, if any, payable pursuant to an Offer or the exercise of the 90% Redemption Right through the issuance of Common Shares. In the event that one or more of such Series 2011-1 Debentures being purchased in accordance with this Section 2.2(i) becomes subject to purchase in part only, upon surrender of such Series 2011-1 Debentures for payment of the Offer Price, the Corporation shall execute and the Trustee shall certify and deliver without charge to the holder thereof or upon the holder's order, one or more new Series 2011-1 Debentures for the portion of the principal amount of the Series 2011-1 Debentures not purchased. Series 2011-1 Debentures for which holders have accepted the Offer and Series 2011-1 Debentures which the Corporation has elected to redeem in accordance with the Change of Control Redemption under this Section 2.2(i) shall become due and payable at the Offer Price on the date of expiry of the Offer or, where has Corporation has elected to redeem in accordance with the 90% Redemption Right under this Section 2.2(i), on the date prescribed in the notice provided pursuant to subsection 2.2(i)(iii), in the same manner and with the same effect as if it were the date of maturity specified in such Series 2011-1 Debentures, anything therein or herein to the contrary notwithstanding, and from and after such date of expiry of the Offer, if the money necessary to purchase or redeem the Series 2011-1 Debentures shall have been deposited as provided in this Section 2.2(i) and affidavits or other proofs satisfactory to the Trustee as to the publication and/or mailing of such notices shall have been lodged with it, interest on the Series 2011-1 Debentures shall cease. If any question shall arise as to whether any notice has been given as above provided and such deposit made, such question shall be decided by the Trustee whose decision shall be final and binding upon all parties in interest. In case the holder of any Series 2011-1 Debenture to be purchased or redeemed in accordance with this Section 2.2(i) shall fail on or before the date specified in Section 2.2(i)(i) or Section 2.2(i)(vi), as applicable, so to surrender such holder's Series 2011-1 Debenture or shall not within such time accept payment of the

-8- monies payable, or give such receipt therefor, if any, as the Trustee may require, such monies may be set aside in trust, either in the deposit department of the Trustee or in a chartered bank, and such setting aside shall for all purposes be deemed a payment to the Debentureholder of the sum so set aside and the Debentureholder shall have no other right except to receive payment of the monies so paid and deposited, upon surrender and delivery up of such holder's Series 2011-1 Debenture. In the event that any money required to be deposited hereunder with the Trustee or any depository or paying agent on account of principal, premium, if any, or interest, if any, on Series 2011-1 Debentures issued hereunder shall remain so deposited for a period of five years less one day from the date of expiry of the Offer, then such monies, together with any accumulated interest thereon, shall at the end of such period be paid over or delivered over by the Trustee or such depository or paying agent to the Corporation and the Trustee shall not be responsible to Debentureholders for any amounts owing to them.

This Series 2011-1 Debenture is one of the Debentures of the Corporation issued or issuable in one or more series under the provisions of the Indenture. The Series 2011-1 Debentures are limited to an aggregate principal amount of up to $46,000,000 in lawful money of Canada.

Upon compliance with the provisions of the Indenture, Series 2011-1 Debentures of any denomination may be exchanged for an equal aggregate principal amount of Series 2011-1 Debentures in any other authorized denomination or denominations. The whole, or if this Series 2011-1 Debenture is in a denomination in excess of $1,000 any part of which is $1,000 or an integral multiple thereof, of the principal of this Series 2011-1 Debenture is convertible, at the option of the holder hereof, upon surrender of this Series 2011-1 Debenture at the principal office of the Trustee in the City of Halifax, at any time prior to 5:00 p.m. (Halifax time) on the earlier of June 30, 2018 and the last Business Day immediately preceding the date specified by the Corporation for redemption of this Series 2011-1 Debenture in accordance with the Indenture (without adjustment for dividends on Common Shares issuable upon conversion) at a conversion price equal to $14.60 such that approximately 68.4932 Common Shares shall be issued for each $1,000 principal amount of Series 2011-1 Debentures so converted, all subject to the terms and conditions and in the manner set forth in the Indenture.

The indebtedness evidenced by this Series 2011-1 Debenture, and by all other Series 2011-1 Debentures now or hereafter certified and delivered under the Indenture, is a direct unsecured obligation of the Corporation, and is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment of all Senior Indebtedness and indebtedness to trade creditors, whether outstanding at the date of the Indenture of thereafter created, incurred, assumed or guaranteed.
