COVENANTS OF BIP AND EXCHANGE LP
		
	2.1
	Covenants Regarding Exchangeable LP Units


So long as any Exchangeable LP Units owned by Non-Affiliated Holders are outstanding, BIP will:
		
	(a)
	not declare or pay any distribution on the BIP Units unless


		
	(i)
	Exchange LP will:


		
	(A)
	simultaneously declare or pay, as the case may be, an equivalent distribution economically equivalent thereto (as determined in accordance with the Unit Provisions) on the Exchangeable LP Units (an “Equivalent Distribution”); and


		
	(B)
	have sufficient money or other assets or authorized but unissued securities available to enable the due declaration and the due and punctual payment, in accordance with applicable Law and the Partnership Agreement, of any Equivalent Distribution on the Exchange LP Units; or


		
	(ii)
	if the distribution is a distribution of BIP Units, in lieu of such a distribution, Exchange LP will:


		
	(A)
	effect a corresponding, contemporaneous and economically equivalent subdivision of the Exchangeable LP Units (as determined in accordance with the Unit Provisions) (an “Equivalent Unit Subdivision”); and


		
	(B)
	have sufficient authorized but unissued securities available to enable the Equivalent Unit Subdivision;


		
	(b)
	advise Exchange LP sufficiently in advance of the declaration by BIP of any distribution on BIP Units and take all such other actions as are reasonably necessary, in cooperation with Exchange LP, to ensure that:


		
	(i)
	the respective declaration date, record date and payment date for an Equivalent Distribution on the Exchangeable LP Units will be the same as the declaration date, record date and payment date for the corresponding distribution on the BIP Units; and


		
	(ii)
	the record date and effective date for an Equivalent Unit Subdivision will be the same as the record date and payment date for the unit distribution, in lieu of such a distribution, on the BIP Units;


		
	(c)
	ensure that the record date for determining unitholders entitled to receive any distribution declared on the BIP Units is not less than ten Business Days after the declaration date for such distribution or such shorter period as may be permitted under applicable Law;


		
	(d)
	take all such actions and do all such things as are reasonably necessary or desirable to enable and permit Exchange LP, in accordance with applicable Law, to pay and otherwise perform its obligations with respect to the satisfaction of the Liquidation Amount, in respect of each issued and outstanding Exchangeable LP Unit held by Non-Affiliated Holders upon the liquidation, dissolution or winding-up of Exchange LP or any other distribution of the assets of Exchange LP among its holders for the purpose of winding up its affairs including all such actions and all such things as are necessary or desirable to enable and permit Exchange LP to cause to be delivered BIP Units to the holders of Exchangeable LP Units in accordance with the provisions of Article 5 of the Unit Provisions;






 - -3 -



		
	(e)
	take all such actions and do all such things as are reasonably necessary or desirable to enable and permit Exchange LP, in accordance with applicable Law, to pay and otherwise perform its obligations with respect to the satisfaction of the Retraction Price and the Redemption Price in respect of each issued and outstanding Exchangeable LP Unit held by Non-Affiliated Holders upon the delivery of a Retraction Request by a holder of any Exchangeable LP Units or a redemption of an Exchangeable LP Unit by Exchange LP, including all such actions and all such things as are necessary or desirable to enable and permit Exchange LP to cause to be delivered BIP Units to the holders of Exchangeable LP Units, in accordance with the provisions of Article 6 or Article 7 of the Unit Provisions, as the case may be; 


		
	(f)
	take all such actions and do all such things as are reasonably necessary or desirable to enable and permit BIP, in accordance with applicable Law, to perform its obligations arising upon the exercise by it of the Liquidation Call Right, the Retraction Call Right or the Redemption Call Right, or upon the occurrence of a liquidation, dissolution or winding up of Exchange LP or any other distribution of the assets of Exchange LP among its holders for the purpose of winding up its affairs, including all such actions and all such things as are necessary or desirable to enable and permit BIP to cause to be delivered BIP Units or other property to the holders of Exchangeable LP Units in accordance with the provisions of the Liquidation Call Right, the Retraction Call Right or the Redemption Call Right, or upon the occurrence of a liquidation, dissolution or winding up of Exchange LP or any other distribution of the assets of Exchange LP among its holders for the purpose of winding up its affairs as the case may be, together with a cheque in respect of any cash portion of the Liquidation Call Purchase Price, Retraction Call Purchase Price, Redemption Call Purchase Price, or Liquidation Amount, as the case may be; and


		
	(g)
	take all such actions and do all such things as are reasonably necessary or desirable to enable and permit Exchange LP and BIP, in accordance with applicable Law, to pay and otherwise perform their obligations with respect to the satisfaction of the BIP Liquidation Amount upon the occurrence of a liquidation, dissolution or winding up of BIP or any other distribution of the assets of BIP among its holders for the purpose of winding up its affairs. 


		
	2.2
	Segregation of Funds


BIP will cause Exchange LP to deposit a sufficient amount of funds in a separate account of Exchange LP and segregate a sufficient amount of such other assets and property as is necessary to enable Exchange LP to pay or otherwise satisfy its obligations with respect to the applicable distribution, Liquidation Amount, Retraction Price or Redemption Price, once such amounts become payable under the terms of this Agreement, the Partnership Agreement or the Unit Provisions, in each case for the benefit of Non-Affiliated Holders from time to time of the Exchangeable LP Units, and Exchange LP will use such funds, assets and property so segregated exclusively for the payment of distributions and the payment or other satisfaction of the Liquidation Amount, the Retraction Price or the Redemption Price, as applicable net of any corresponding withholding Tax obligations and for the remittance of such withholding Tax obligations.
		
	2.3
	Reservation of BIP LP Units


BIP hereby represents, warrants and covenants in favour of Exchange LP that BIP has reserved for issuance and will, at all times while any Exchangeable LP Units are outstanding, keep available, free from pre-emptive and other rights, such number of BIP Units (or other securities into which BIP Units may be reclassified or changed as contemplated by Section 2.7): (a) as is equal to the sum of (i) the number of Exchangeable LP Units issued and outstanding from time to time, and (ii) the number of Exchangeable LP Units issuable upon the exercise of all rights to acquire Exchangeable LP Units outstanding from time to time; and (b) as are now and may hereafter be required to enable and permit each of BIP and Exchange LP to meet its obligations under the Partnership Agreement, this Agreement and the Unit Provisions and any other security or commitment pursuant to the Arrangement with respect to which BIP and Exchange LP may now or hereafter be required to issue and/or deliver BIP Units to the Non-Affiliated Holders.
		
	2.4
	Notification of Certain Events


In order to assist BIP to comply with its obligations hereunder and to permit BIP to exercise the Liquidation Call Right, Retraction Call Right and Redemption Call Right, as applicable, Exchange LP will notify BIP of each of the following events at the time set forth below:




 - -4 -



		
	(a)
	in the event of any determination by the Board of Directors to institute voluntary liquidation, dissolution or winding-up proceedings with respect to Exchange LP or to effect any other distribution of the assets of Exchange LP among its holders for the purpose of winding up its affairs, at least 30 days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution;


		
	(b)
	promptly upon the earlier of (i) receipt by Exchange LP of notice of, and (ii) Exchange LP otherwise becoming aware of any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of Exchange LP or to effect any other distribution of the assets of Exchange LP among its holders for the purpose of winding up its affairs;


		
	(c)
	immediately upon receipt by Exchange LP of a Retraction Request;


		
	(d)
	on the same date on which notice of redemption is given to holders of Exchangeable LP Units, in the event of any determination of a Redemption Date in accordance with the Unit Provisions; and


		
	(e)
	promptly upon the issuance by Exchange LP of any Exchangeable LP Units or rights to acquire Exchangeable LP Units (other than the issuance of Exchangeable LP Units or rights to acquire Exchangeable LP Units pursuant to the Arrangement).


		
	2.5
	Delivery of BIP Units


Upon notice from Exchange LP of any event that requires Exchange LP to cause to be delivered BIP Units to any holder of Exchangeable LP Units, BIP will, forthwith, issue and deliver or cause to be delivered the requisite number of BIP Units to Exchange LP, and Exchange LP will forthwith deliver or cause to be delivered the requisite number of BIP Units to or for the benefit of the former holder of the surrendered Exchangeable LP Units. All such BIP Units will be duly authorized and validly issued as fully paid, non-assessable, free of pre-emptive rights and will be free and clear of any lien, claim or encumbrance.
		
	2.6
	Qualification of BIP Units


BIP covenants that it will use its reasonable best efforts to make such filings and seek such regulatory consents and approvals as are necessary so that the BIP Units to be issued to holders of Exchangeable LP Units pursuant to the terms of the Partnership Agreement, the Unit Provisions and this Agreement will be issued in compliance with the applicable securities Laws in Canada and may be freely traded thereafter (other than by reason of a holder being a “control person” of BIP for purposes of Canadian federal, provincial or territorial securities Laws, if applicable). BIP will in good faith expeditiously take all such actions and do all such things as are reasonably necessary or desirable to cause all BIP Units to be delivered hereunder to be listed, quoted and posted for trading on all stock exchanges and quotation systems on which outstanding BIP Units have been listed by BIP and remain listed and are quoted or posted for trading at such time.
Notwithstanding any other provision of the Partnership Agreement, the Unit Provisions, any term of this Agreement or the Arrangement, no BIP Units will be issued (and BIP will not be required to issue any BIP Units) in connection with any liquidation, dissolution or winding-up of Exchange LP, or any retraction, redemption or any other exchange, direct or indirect, of Exchangeable LP Units, if such issuance of BIP Units would not be permitted by applicable Laws.
		
	2.7
	Economic Equivalence


So long as any Exchangeable LP Units owned by Non-Affiliated Holders are outstanding:
		
	(a)
	BIP will not without prior approval of Exchange LP and the prior approval of the holders of the Exchangeable LP Units given in accordance with Section 10.2 of the Unit Provisions:


		
	(i)
	issue or distribute BIP Units (or securities exchangeable for or convertible into or carrying rights to acquire BIP Units) to the holders of all or substantially all of the then outstanding BIP Units by way of a stock distribution or other distribution, other than an issue of BIP Units (or securities exchangeable for or convertible into or carrying rights to acquire BIP Units) to holders of BIP Units who: (A) exercise an option to receive distributions in BIP Units (or securities exchangeable for or convertible into or carrying rights to acquire BIP Units) in lieu of receiving cash distributions; or (B) pursuant to any distribution reinvestment plan, scrip distribution or similar arrangement; or






 - -5 -



		
	(ii)
	issue or distribute rights, options or warrants to the holders of all or substantially all of the then outstanding BIP Units entitling them to subscribe for or to purchase BIP Units (or securities exchangeable for or convertible into or carrying rights to acquire BIP Units); or


		
	(iii)
	issue or distribute to the holders of all or substantially all of the then outstanding BIP Units (A) units or securities of BIP of any class other than BIP Units (or securities convertible into or exchangeable for or carrying rights to acquire such securities), (B) rights, options or warrants other than those referred to in Section 2.7(a)(ii) above, (C) evidences of indebtedness of BIP; or (D) assets of BIP;


unless (x) Exchange LP is permitted under applicable Law to issue or distribute the economic equivalent on a per unit basis of such rights, options, warrants, securities, units, evidences of indebtedness or other assets to holders of the Exchangeable LP Units and (y) Exchange LP will issue or distribute the economic equivalent of such rights, options, warrants, securities, units, evidences of indebtedness or other assets simultaneously to holders of the Exchangeable LP Units.
		
	(b)
	BIP will not without the prior approval of Exchange LP and the prior approval of the holders of the Exchangeable LP Units given in accordance with Section 10.2 of the Unit Provisions:


		
	(i)
	subdivide, redivide or change the then outstanding BIP Units into a greater number of BIP Units; or


		
	(ii)
	reduce, combine, consolidate or change the then outstanding BIP Units into a lesser number of BIP Units; or


		
	(iii)
	reclassify or otherwise change the rights, privileges or other terms of the then outstanding BIP Units or effect a merger, reorganization or other transaction involving or affecting the BIP Units; 


unless (x) Exchange LP is permitted under applicable Law to make the same or an economically equivalent change to, or in the rights of holders of, the Exchangeable LP Units, and (y) the same or an economically equivalent change is made simultaneously to, or in the rights of the holders of, the Exchangeable LP Units.
		
	(c)
	BIP will ensure that the record date for any event referred to in Section 2.7(a) or Section 2.7(b), or (if no record date is applicable for such event) the effective date for any such event, is not less than ten Business Days after the date on which such event is declared or announced by BIP (with simultaneous notification thereof by BIP to Exchange LP).


		
	(d)
	The Board of Directors will determine, acting in good faith and in its sole discretion (with the assistance of such reputable and qualified independent financial advisors and/or other experts as the Board of Directors may require), economic equivalence for the purposes of any event referred to in Section 2.7(a) or Section 2.7(b) and each such determination will be conclusive and binding on BIP. In making each such determination, the following factors will, without excluding other factors determined by the Board of Directors to be relevant, be considered by the Board of Directors:


		
	(i)
	in the case of any stock distribution or other distribution payable in BIP Units, the number of such units issued in proportion to the number of BIP Units previously outstanding;


		
	(ii)
	in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase BIP Units (or securities exchangeable for or convertible into or carrying rights to acquire BIP Units), the relationship between the exercise price of each such right, option or warrant and the Current Market Price, the volatility of the BIP Unit and the term of any such instrument;


		
	(iii)
	in the case of the issuance or distribution of any other form of property (including any units or securities of BIP of any class other than BIP Units, any rights, options or warrants other than those referred to in Section 2.7(d)(ii), any evidences of indebtedness of BIP or any assets of BIP), the relationship between the fair market value (as determined by the Board of Directors in the manner contemplated above) of such property to be issued or distributed with respect to each outstanding BIP Units and the Current Market Price;






 - -6 -



		
	(iv)
	in the case of any subdivision, redivision or change of the then outstanding BIP Units into a greater number of BIP Units or the reduction, combination, consolidation or change of the then outstanding BIP Units into a lesser number of BIP Units or any merger, reorganization or other transaction affecting the BIP Units, the effect thereof upon the then outstanding BIP Units; and


		
	(v)
	in all such cases, the general taxation consequences of the relevant event to holders of Exchangeable LP Units compared to holders of BIP Units (including to the extent that such consequences may differ as a result of differences between taxation Laws of Canada and Bermuda) except for any differing consequences arising as a result of differing marginal taxation rates and without regard to the individual circumstances of holders of Exchangeable LP Units.


		
	(e)
	Exchange LP agrees that, to the extent required, upon due notice from BIP, Exchange LP will use its best efforts to take or cause to be taken such steps as may be necessary for the purposes of ensuring that appropriate distributions are made by Exchange LP, or subdivisions, redivisions or changes are made to the Exchangeable LP Units, in order to implement the required economic equivalence with respect to the BIP Units and the Exchangeable LP Units as provided for in this Section 2.7.


		
	2.8
	Tender Offers


In the event that a cash offer, unit exchange offer, issuer bid, take-over bid or similar transaction with respect to BIP Units (a “Tender Offer”) is proposed by BIP or is proposed to BIP or its holders and is recommended by the board of directors of its general partner, or is otherwise effected or to be effected with the consent or approval of the board of directors of its general partner, and the Exchangeable LP Units are not redeemed by Exchange LP pursuant to the Redemption Call Right, BIP and Exchange LP will use reasonable best efforts (to the extent, in  the case of a Tender Offer by a third party, within its control) expeditiously and in good faith to take all such actions and do all such things as are necessary or desirable to enable and permit holders of Exchangeable LP Units to participate in such Tender Offer to the same extent and on an economically equivalent basis as the holders of BIP Units, without discrimination. Without limiting the generality of the foregoing, BIP and Exchange LP will use reasonable best efforts expeditiously and in good faith to ensure that holders of Exchangeable LP Units may participate in each such Tender Offer without being required to retract Exchangeable LP Units as against Exchange LP (or, if so required, to ensure that any such retraction, will be effective only upon, and will be conditional upon, the closing of such Tender Offer and only to the extent necessary to tender or deposit to the Tender Offer). Nothing herein will affect the right of Exchange LP to redeem, or BIP to purchase pursuant to the Redemption Call Right, Exchangeable LP Units in the event of a BIP Liquidity Transaction.
		
	2.9
	BIP and Subsidiaries Not To Vote Exchangeable LP Units


BIP and each Subsidiary covenant and agree that it will appoint and cause to be appointed proxyholders with respect to all Exchangeable LP Units held by it for the sole purpose of attending each meeting of holders of Exchangeable LP Units in order to be counted as part of the quorum for each such meeting. BIP further covenants and agrees that it will not, and will cause its Subsidiaries not to, exercise any voting rights that may be exercisable by holders of Exchangeable LP Units from time to time pursuant to the Unit Provisions, the Partnership Agreement or pursuant to the provisions of the Limited Partnerships Act (or any successor or other corporate statute by which Exchange LP may in the future be governed) with respect to any Exchangeable LP Units held by it or by its Subsidiaries in respect of any matter considered at any meeting of holders of Exchangeable LP Units.
		
	2.10
	Ownership of Outstanding Units


Without the prior approval of Exchange LP and the prior approval of the holders of the Exchangeable LP Units given in accordance with Section 10.2 of the Unit Provisions, BIP covenants and agrees in favour of Exchange LP that, as long as any outstanding Exchangeable LP Units are owned by Non-Affiliated Holders, BIP will be and remain the direct or indirect beneficial owner of all issued and outstanding general partner units and Class A limited partnership units of Exchange LP. Notwithstanding the foregoing, BIP will not be in violation of this Section 2.10 if any person or group of persons acting jointly or in concert acquires all or substantially all of the assets of BIP or the BIP Units.
		
	2.11
	Ordinary Market Purchases


For greater certainty, nothing contained in this Agreement, including without limitation the obligations of BIP contained in Section 2.8, will limit the ability of BIP (or any of its Subsidiaries including, without limitation, Exchange LP) to make ordinary market purchases of BIP Units in accordance with applicable Laws and regulatory or stock exchange requirements.

	2.12
	Due Performance


On and after the Effective Date, BIP and Exchange LP will duly and timely perform all of their obligations under the Partnership Agreement, this Agreement and the Unit Provisions.
ARTICLE 3
BIP SUCCESSORS
		
	3.1
	Certain Requirements in Respect of Combination, etc.


BIP will not enter into any transaction (whether by way of reconstruction, reorganization, consolidation, transfer, sale, lease or otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person unless:
		
	(a)
	such other Person or continuing entity (the “BIP Successor”) by operation of Law, becomes, without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, an agreement supplemental hereto and such other instruments (if any) as are necessary or advisable to evidence the assumption by the BIP Successor of liability for all moneys payable and property deliverable hereunder and the covenant of such BIP Successor to pay and deliver or cause to be delivered the same and its agreement to observe and perform all the covenants and obligations of BIP under this Agreement; and


		
	(b)
	such transaction will be upon such terms and conditions as substantially to preserve and not to impair in any material respect any of the rights, duties, powers and authorities of the other parties hereunder or the holders of Exchangeable LP Units.


		
	3.2
	Vesting of Powers in Successor


Whenever the conditions of Section 3.1 have been duly observed and performed, the parties, if required by Section 3.1, will execute and deliver the supplemental agreement provided for in Section 3.1(a) and thereupon the BIP Successor and such other person that may then be the issuer of the BIP Units will possess and from time to time may exercise each and every right and power of BIP under this Agreement in the name of BIP or otherwise and any act or proceeding by any provision of this Agreement required to be done or performed by the board of directors of the general partner of BIP may be done and performed with like force and effect by the directors or officers of such BIP Successor.
		
	3.3
	Wholly-Owned Subsidiaries


Nothing herein will be construed as preventing the merger of any direct or indirect wholly-owned Subsidiary of BIP with or into BIP or another direct or indirect wholly-owned Subsidiary of BIP or the winding-up, liquidation or dissolution of any direct or indirect wholly-owned Subsidiary of BIP, provided that all of the assets of such Subsidiary are transferred to BIP or another direct or indirect wholly-owned Subsidiary of BIP, and any such transactions are expressly permitted by this Article 3.
		
	3.4
	Successor Transaction


Notwithstanding the foregoing provisions of Article 3, in the event of a BIP Liquidity Transaction:
		
	(a)
	in which BIP merges with, or in which all or substantially all of the then outstanding BIP Units are acquired by, one or more other entity to which BIP is, immediately before such merger or acquisition, “related” within the meaning of the Tax Act (otherwise than by virtue of a right referred to in paragraph 251(5)(b) thereof);


		
	(b)
	which does not result in an acceleration of the Redemption Date in accordance with paragraph (b) of that definition in the Unit Provisions; and


		
	(c)
	in which all or substantially all of the then outstanding BIP Units are converted into or exchanged for securities or rights to receive such securities (the “Other Units”) of another entity (the “Other Entity”) that, immediately after such BIP Liquidity Transaction, is the successor to, or owns or controls, directly or indirectly, BIP,






 - -8 -



then all references herein to “BIP” will thereafter be and be deemed to be references to “Other Entity” and all references herein to “BIP Units” will thereafter be and be deemed to be references to “Other Units” (with appropriate adjustments, if any, as are required to result in a holder of Exchangeable LP Units on the exchange, redemption or retraction of such units pursuant to the Unit Provisions immediately subsequent to the BIP Liquidity Transaction being entitled to receive that number of Other Units equal to the number of Other Units such holder of Exchangeable LP Units would have received if the exchange, redemption or retraction of such units pursuant to the Unit Provisions had occurred immediately prior to the BIP Liquidity Transaction and the BIP Liquidity Transaction was completed), but subject to subsequent adjustments to reflect any subsequent changes in the capital of the issuer of the Other Units, including without limitation, any subdivision, consolidation or reduction of capital, without any need to amend the terms and conditions of the Exchangeable LP Units and without any further action required.
ARTICLE 4
GENERAL
		
	4.1
