	 	(iii)	Additional payments based on the Executive’s length of service with the Company, calculated as Executive’s monthly base salary for the number of months set forth in the

	 	(iv)	An amount equal to 1/12 of the Performance Bonus payments earned by Executive during the bonus year preceding the current bonus year times the number of months referred to in the

the Corporation gives notice, the date specified by the Corporation as the date on which the Executive’s employment will terminate) shall terminate and be of no further force and effect as of the Date of Termination and neither any period of
notice nor any payment in lieu thereof upon termination of employment hereunder shall be considered as extending the period of employment for the purposes of vesting of options notwithstanding anything to the contrary in any other agreement between
the Corporation and the Executive. Notwithstanding anything contained in this Section 13, in the event of termination by the Corporation other than for Just Cause, the Executive shall have the right to exercise any options which are vested as
at the Date of Termination for the 90 Day Period as defined in Section 12(d). Any unvested options which would have otherwise vested during such 90 Day Period shall continue to vest during that period and to the extent any unvested options have
vested during such 90 Day Period, the Executive shall also be entitled to exercise those options within a rolling 90 day period after the date of vesting of such options, which period will not exceed 180 days following the Date of Termination. In
addition, notwithstanding anything contained in this Section 13 or elsewhere in this Agreement, in the event of termination due to death of the Executive, the estate of the Executive shall be entitled, at any time during the period which is 12

of vesting and ends 12 months from the date of death of the Executive.

terminated for Just Cause, Death or if the Executive’s employment hereunder is terminated by the Executive pursuant to Section 12(d) then no payment whatsoever shall be made to the Executive under Sections 13(b).

Directors, at a meeting duly called and held prior to the execution and delivery of this Agreement, acting on the unanimous recommendation in favour of the Arrangement by the special committee of the Hummingbird Board of Directors, has duly and
unanimously (with the exception of Andrew J. Malik, who has abstained from voting solely due to his being a Managing Director of Lehman Brothers Inc., a financial advisor to the Board of Directors of Hummingbird and the Special Committee of the
Board of Directors of Hummingbird), adopted resolutions:

	 	(E)	directing that the Arrangement Resolution be submitted to a vote at a meeting of Hummingbird Shareholders, and 

  

	 	(F)	recommending that Hummingbird Shareholders approve the Arrangement Resolution,

its properties as now owned and to carry on its business as it is now being conducted. Hummingbird and each of its subsidiaries is registered, qualified or otherwise authorized to do business and each is, to the extent that such concept is legally
recognized, in good standing in each jurisdiction in which the character of its properties, owned, leased, licensed or otherwise held, or the nature of its activities makes such registration necessary, except where the failure to be so registered or

no steps or proceedings have been taken or are pending or contemplated to amend or supersede such constating documents. Section 3.1(b) of the Disclosure Letter sets forth a correct and complete list of each jurisdiction where Hummingbird or any

Acquisition Sub, constitutes a legal, valid and binding obligation of Hummingbird enforceable against Hummingbird in accordance with its terms, subject to the qualification that such enforceability may be limited by bankruptcy,

Hummingbird (including Hummingbird Shares). All outstanding Hummingbird Shares have been duly authorized and validly issued, are fully paid and non-assessable and are not subject to, nor were they issued in violation of, any pre-emptive rights, and
all Hummingbird Shares issuable upon the exercise of rights under the Hummingbird Options in accordance with their respective terms have been duly authorized and, upon issuance, will be validly issued as fully paid and non-assessable and will not be

 - 19 - 

	 	 
thereof and subject to the qualifications and limitations set forth therein, the Purchase Price to be received under the Arrangement by the holders of

Laws. The Interim Financials will be prepared in accordance with GAAP consistently applied (except (a) as otherwise indicated in such financial statements and the notes thereto, (b) as unaudited interim statements they are subject to
normal year-end adjustments and may omit notes which are not required by applicable Laws in the unaudited statements or (c) as items in such financial statements have been reclassified) and will fairly present, in all material respects, the
consolidated financial position, results of operations and changes in financial position of Hummingbird and its subsidiaries as of the dates thereof and for the periods indicated therein (subject to normal period-end adjustments) and reflect

Hummingbird Options are not approved by Hummingbird Shareholders at the Meeting in accordance with applicable law and stock exchange requirements, Hummingbird agrees to, promptly following the effectiveness of the Arrangement on the Effective Date,
make or cause to be made to each of such individuals in respect of each of his 50,000 Hummingbird Options purported to be held a cash payment equal to the amount (if any) by which the Purchase Price exceeds the product of (x) the exercise price

 ARTICLE 7 
 ADDITIONAL AGREEMENTS

  

	7.1	Non-Solicitation 

 (1) Hummingbird shall not,
directly or indirectly, through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries, (a) solicit, initiate, facilitate or encourage (including by way of furnishing information or entering into any
form of agreement, arrangement or understanding, but excluding compliance by Hummingbird with its continuous reporting obligations under applicable securities Laws in the ordinary course consistent with past practice) any inquiries or proposals
regarding, constituting or that would reasonably be expected to lead to, an Acquisition Proposal, (b) participate in any discussions or negotiations regarding an Acquisition Proposal, (c) withdraw or modify, or propose publicly to withdraw
or modify, in a manner adverse to Parent, the approval of the Board of Directors of Hummingbird of the Plan of Arrangement, (d) approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal or (e) accept or
enter into, or propose publicly to accept or enter into, any agreement, understanding or arrangement in respect of an Acquisition Proposal; provided that nothing contained in this Agreement shall prevent the Board of Directors of Hummingbird from
taking any of the actions described in clauses (a) through (e) above in respect of an unsolicited bona fide written Acquisition Proposal received after the date hereof that: 
  

	 	(a)	did not result from a breach of any agreement between the person making such Acquisition Proposal and Hummingbird or any of its subsidiaries, or this Section 7.1;

  

	 	(b)	involves not less than 66 2/3 percent of the
outstanding Hummingbird Shares or not less than 66 2/3 percent of the consolidated assets (measured on a fair
value) of Hummingbird; and 

  

	 	(c)	 in respect of which the Board of Directors of Hummingbird determines in its good faith judgment pursuant to the exercise of its fiduciary duties under applicable
Laws, after consultation with its financial advisors and its outside counsel, that there is a substantial likelihood that any required financing will be obtained and that the Acquisition Proposal would, if consummated in accordance with its terms
(but not assuming away any risk of non-completion), result in a transaction that: (i) is reasonably capable of completion in accordance with its terms without significant additional delay, taking into account all legal, financial, regulatory,

  

 - 49 - 

	 	 
financing and other aspects of such Acquisition Proposal and the person making such Acquisition Proposal; and (ii) is more favourable from a financial
point of view to Hummingbird Shareholders than under the Plan of Arrangement on a cash-equivalent basis taking into account any approval requirements and all other financial, legal, regulatory and other aspects of such proposal (including any
proposal made by Parent or Acquisition Sub in response to such Acquisition Proposal or otherwise) 

 (any such Acquisition Proposal being
referred to herein as a “Superior Proposal”). 
 (2) Hummingbird shall, and shall cause the officers, directors,
employees, representatives and agents of Hummingbird and its subsidiaries to, immediately terminate any existing discussions or negotiations with any parties (other than Parent) with respect to any proposal that constitutes, or may reasonably be
expected to constitute, an Acquisition Proposal. Hummingbird agrees not to release any third party from (a) any confidentiality agreement or (b) any standstill agreement or provision in each case to which such third party is a party unless
such third party has made a Superior Proposal and Hummingbird has accepted such Superior Proposal. Hummingbird shall immediately following the public announcement by the Parties of this Agreement request the return or destruction of all information
provided to any third party which, at any time since January 1, 2005, has entered into a confidentiality agreement with Hummingbird relating to a potential Acquisition Proposal except to the extent that a request has previously been made that
such information be returned or destroyed, and, upon the request of Parent, shall use all commercially reasonable efforts to ensure that such requests are honoured. 
 (3) Hummingbird shall immediately notify Parent of, at first orally and then, within 24 hours, in writing, any Acquisition Proposal or inquiry that would reasonably be expected to lead to an Acquisition Proposal, in
each case received after the date hereof of which any of its directors or officers become aware, or any amendments to the foregoing, or any request for nonpublic information relating to Hummingbird or any of its subsidiaries in connection with an
Acquisition Proposal or for access to the properties, books or records of Hummingbird or any of its subsidiaries by any person that informs Hummingbird or such subsidiary that it is considering making, or has made, an Acquisition Proposal and any
amendment thereto. Hummingbird shall keep Parent promptly and reasonably informed from time to time of the status, including any change to the material terms of any such Acquisition Proposal or inquiry. Such notice shall include or be accompanied by
a copy of all documentation relating to any Acquisition Proposal and any amendment thereto and a description of all material terms of any oral or other communications related to any Acquisition Proposal, including the identity of the person making
such Acquisition Proposal and such other details as Parent may reasonably request. 
 (4) If Hummingbird receives a request for material
non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal, Hummingbird may request clarifications in writing from such person solely for purposes of valuing, and solely in respect of, any non-cash consideration
that is offered under such Acquisition Proposal, provided that such clarifications are reasonably necessary as part of the efforts of the Board of Directors of Hummingbird to ascertain whether such Acquisition Proposal is, or is reasonably likely to
be, if consummated in accordance with its terms, a Superior Proposal. If Hummingbird receives a request for material non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal and the Board of Directors of
Hummingbird determines that such proposal would reasonably likely be, if consummated in accordance with its terms, a Superior Proposal, 

  

 - 50 - 

 
then, and only in such case, the Board of Directors of Hummingbird may, subject to the execution by such person of a confidentiality agreement having
substantially, the same terms as the Non-Disclosure Agreement, provide such person with access in accordance with subsection (1) to such information regarding Hummingbird, acting reasonably, provided however that the person making the
Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal, and provided further that Hummingbird sends immediately a copy of any such confidentiality agreement to Parent upon its execution and Parent is immediately
provided with a list and copies of all information provided to such person not previously provided to Parent and is immediately provided with access to information similar to that which was provided to such person. 
 (5) Hummingbird shall ensure that its officers and directors and those of its subsidiaries and any financial or other advisors, agents or representatives
retained by it are aware of the provisions of this Section, and Hummingbird shall be responsible for any breach of this Section by any such person or its advisors or representatives. 
 (6) Nothing contained in this Section 7.1 shall prohibit the Board of Directors of Hummingbird from making any disclosure to all of the Hummingbird
Shareholders prior to the Outside Date if, in the good faith judgment of the Board of Directors of Hummingbird, after consultation with outside counsel, the failure to make such disclosure would be inconsistent with its fiduciary duties or would
contravene applicable Laws (including Section 99 of the Securities Act (Ontario)), provided that any such disclosure that relates to an Acquisition Proposal shall be deemed to constitute a basis for termination of this Agreement by
Parent pursuant to Section 8.2(1)(e) unless the Board of Directors of Hummingbird reaffirms its recommendation to the Hummingbird Shareholders to accept the Offer in such disclosure. 
  

	7.2	Right to Match 

 (1) Subject to
Section 7.2(2), Hummingbird covenants that it will not accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Superior Proposal (other than a confidentiality agreement permitted by
Section 7.1(4)) unless: 
  

	 	(a)	Hummingbird has complied with its obligations under Section 7.1 and the other provisions of this Article 7 and has provided Parent with a copy of all material documentation and
a summary of any material oral or other communications relating to the Superior Proposal (the “Superior Proposal Information”); 

  

	 	(b)	a period (the “Response Period”) of five (5) business days shall have elapsed from the date on which Parent received both the Superior Proposal Information
together with written notice from the Board of Directors of Hummingbird that the Board of Directors of Hummingbird determined, subject only to compliance with this Section 7.2, to accept, approve, recommend or enter into a binding agreement to
proceed with the Superior Proposal Information; and 

  

	 	(c)	if the Response Period would not terminate on or before the date fixed for the Meeting, Hummingbird shall, upon the written request of Parent, adjourn the Meeting to a date selected
by Parent that is not less than two nor more than 20 business days after the expiration of the Response Period. 

  

 - 51 - 

 (2) During the Response Period, Parent will have the right, but not the obligation, to offer to amend the
terms of the Transactions. The Board of Directors of Hummingbird will review any such proposal by Parent to amend the terms of the Transactions, including an increase in, or modification of, the consideration to be received by the holders of
Hummingbird Shares, to determine whether the Acquisition Proposal to which Parent is responding would be a Superior Proposal when assessed against the Transactions as it is proposed by Parent to be amended. If the Board of Directors of Hummingbird
does not so determine, the Board of Directors of Hummingbird will promptly reaffirm its recommendation of the Transactions as amended and Hummingbird will not implement the proposed Superior Proposal. If the Board of Directors of Hummingbird does so
determine, Hummingbird may on termination of this Agreement in accordance with Section 8.2(1)(g) and payment of the fee to Parent pursuant to Section 7.3, approve, recommend, accept or enter into an agreement, understanding or arrangement
to proceed with the Superior Proposal. 
 (3) Each successive amendment to any Acquisition Proposal that results in an increase in, or
modification of, the consideration (or value of such consideration) to be received by the holders of Hummingbird Shares shall constitute a new Acquisition Proposal for the purposes of this Section 7.2 and Parent shall be afforded a new Response
Period in respect of each such Acquisition Proposal. 
  

	7.3	Certain Payments 

 (1) Notwithstanding any
other provision relating to the payment of fees, including the payment of brokerage fees, in the event that: 
  

	 	(a)	Parent has terminated this Agreement pursuant to Section 8.2(1)(e); 

  

	 	(b)	Hummingbird has terminated this Agreement pursuant to Section 8.2(1)(g); 

  

	 	(c)	(i) (A)(1) this Agreement has been terminated pursuant to Section 8.2(1)(h) or 8.2(1)(i) and (2) the Arrangement has failed to receive the requisite approval of the
Hummingbird Shareholders in accordance with applicable Law; or 

 (B)(1) this Agreement has been terminated pursuant to
Section 8.2(1)(c), provided that in the case of a breach of a representation or warranty such breach was made knowingly by Hummingbird; 
 (ii) an Acquisition Proposal has been negotiated or discussed with Hummingbird (directly or indirectly through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries), made or publicly announced
or an inquiry to Hummingbird (directly or indirectly through any officer, director, employee, representative or agent of Hummingbird or any of its subsidiaries) concerning an Acquisition Proposal has been made, in each case prior to the termination
of this Agreement; and 
 (iii) (A) an agreement or a letter of intent in respect of any Acquisition Proposal has been entered into by
Hummingbird on or before the first anniversary 

  

 - 52 - 

 
of the termination of this Agreement and such Acquisition Proposal has been completed; or 
 (B) any Acquisition Proposal, in respect of which Hummingbird has not entered into an agreement or a letter of intent, has been completed on or before the
first anniversary of the termination of this Agreement; or 
  

	 	(d)	Hummingbird has breached its obligations under Section 7.1 or Section 7.2, 

 then Hummingbird shall promptly, but in no event later than the Payment Deadline (defined below), make a payment to Parent in the amount of $12,356,544, less any amounts paid to Parent pursuant to Section 7.4 by
wire transfer of immediately available funds to an account designated by Parent. Hummingbird acknowledges that the agreements contained in this Section 7.3(1) are an integral part of the transactions contemplated by this Agreement, and that,
without these agreements, Parent and Acquisition Sub would not enter into this Agreement. Notwithstanding anything to the contrary, this Section 7.3 shall survive completion of any and all of the Transactions. Payment Deadline means: the fifth
business day following termination of this Agreement in the case of a payment to be made under Section 7.3(1)(a); the time of termination of this Agreement in the case of a payment to be made under Section 7.3(1)(b); the fifth business day
following completion of an Acquisition Proposal in the case of a payment to be made under Section 7.3(1)(c); and the fifth business day following Parent’s request for payment in the case of a payment to be made under
Section 7.3(1)(d). 
  

	7.4	Fees and Expenses 

 (1) Subject to
subsections (2) and (3) of this Section 7.4, each Party shall pay all fees, costs and expenses, including legal fees, accounting fees, financial advisory fees, regulatory fees, stock exchange fees, disbursements of advisors and
printing and mailing costs, incurred by such Party in connection with this Agreement and the Transactions and any financing thereof. 
 (2)
In the event that: 
  

	 	(a)	this Agreement is terminated pursuant to Section 8.2(1)(a) or 8.2(1)(c); or 

  

	 	(b)	(i)this Agreement is terminated pursuant to Section 8.2(1)(h) or 8.2(1)(i); and 

 (ii) the Arrangement has failed to receive the requisite approval of the Hummingbird Shareholders in accordance with applicable Law, then Hummingbird shall promptly, but in no event later than five business days
following the request by Parent, pay all of the charges and expenses incurred by Parent and Acquisition Sub in connection with this Agreement and the Transactions and the financing thereof, subject to a maximum of $2,000,000 (which maximum amount
will be reduced to $1,000,000 if the Agreement has been terminated pursuant to Section 8.2(1)(i) in circumstances where the Hummingbird Shareholders have voted on the Arrangement Resolution at the Meeting but the Arrangement Resolution failed
to receive the requisite approval of at least two-thirds of the votes cast at the Meeting), as reimbursement to Parent and Acquisition Sub payable by wire transfer of same day funds to or to the order 

  

 - 53 - 

	 	 
of Parent, provided however, that no payment under Section 7.4(2) shall be made if a payment has been made under Section 7.3.

 (3) Each Party acknowledges that the agreements contained in this Section 7.4 are an integral part of the
transactions contemplated by this Agreement, and that, without these agreements, neither Party would enter into this Agreement. Notwithstanding anything to the contrary, this Section 7.4 shall survive completion of any and all of the
Transactions. 
  

	7.5	Liquidated Damages and Injunctive Relief 

 Each of the Parties acknowledges that all of the payment amounts set out in Sections 7.3 and 7.4 are payments of liquidated damages which are a genuine pre-estimate of the damages Parent and Acquisition Sub, on the one hand, or Hummingbird,
on the other hand (as the case may be) will suffer or incur as a result of the event giving rise to such payment and the resultant termination of this Agreement and are not penalties. Each of the Parties irrevocably waives any right it may have to
raise as a defense that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that, subject to Sections 7.3 and 7.4, payment of the amounts determined pursuant to Sections 7.3 and/or 7.4 in the manner
provided in respect thereof is the sole monetary remedy of the Party receiving such payment. Nothing contained herein shall preclude a Party from seeking injunctive relief to restrain any breach or threatened breach of the covenants or agreements
set forth in this Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith. 
  

	7.6	Access to Information; Confidentiality 

 (1)
From the date hereof until the earlier of the Effective Time and the termination of this Agreement, upon reasonable notice and subject to applicable Law, including pre-merger notification and other competition law requirements, Hummingbird shall,
and shall cause its subsidiaries and their respective officers, directors, employees, independent auditors, accounting advisers and agents to, afford to Parent and to the officers, employees, agents and representatives of Parent such access as
Parent may reasonably require at all reasonable times, including for the purpose of facilitating integration business planning, to their officers, employees, agents, properties, books, records and Contracts, and shall furnish Parent with all data
and information as Parent may reasonably request. Parent and Hummingbird acknowledge and agree that information furnished pursuant to this Section shall be subject to the terms and conditions of the Non-Disclosure Agreement. 
 (2) Parent and Hummingbird acknowledge that information received pursuant to this Section 7.6 may be personal information under applicable privacy
and other Laws, or non-public or proprietary in nature and therefore all such information shall be deemed to be and shall be treated as confidential information for purposes of the Non-Disclosure Agreement. Parent and Hummingbird further acknowledge
their obligation to maintain the confidentiality of such confidential information in accordance with the Non-Disclosure Agreement. If any material is withheld by Hummingbird or any of its subsidiaries because of the confidential nature of such
material, or otherwise, Hummingbird or such subsidiary shall inform Parent as to the general nature of what is being withheld and such information may, in the sole discretion of Hummingbird, be disclosed to external advisors of Parent. 

 

 - 54 - 

	7.7	Insurance and Indemnification 

 (1) Parent
will, or will cause Acquisition Sub to, at Parent’s option, either (a) maintain in effect without any reduction in scope or coverage for not less than six years from the Effective Date customary policies of directors’ and
officers’ liability insurance providing protection no less favourable to the protection provided by the policies maintained by Hummingbird in favour of the directors and officers of Hummingbird and each of its subsidiaries which are in effect
immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred prior to the Effective Time or (b) purchase as an extension of Hummingbird’s current insurance policies,
prepaid non cancellable run-off directors’ and officers’ liability insurance providing coverage comparable to that contained in Hummingbird’s existing policy for six years from the Effective Time with respect to claims arising from or
related to facts or events that occurred at or prior to the Effective Time. 
 (2) Parent agrees that all rights to indemnification or
exculpation existing in favour of the directors or officers of Hummingbird or any subsidiary of Hummingbird as at the date of the Non-Disclosure Agreement (the “Hummingbird D&O Rights”) as provided in Hummingbird’s articles
or by-laws or as disclosed in Section 7.7 of the Disclosure Letter shall survive the transactions contemplated hereby and shall continue in full force and effect for a period of not less than six years from the Effective Time. For a period of
six years from the Effective Date, Parent will, or will cause Acquisition Sub or Hummingbird to, perform the obligations of Hummingbird under the Hummingbird D&O Rights. 
 (3) In the event Hummingbird or any of its successors or assigns (a) consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or (b) transfers all or substantially all of its properties and assets to any person, then, and in such case, proper provision shall be made so that such successors
and assigns of Hummingbird or, at Parent’s option, Parent, shall assume the obligations set forth in this Section 7.7. 
 (4) This Section 7.7 shall survive the consummation of the Arrangement, is intended to benefit Hummingbird and each of its directors and officers and their respective heirs and personal representatives and shall be enforceable by such
directors and officers and their respective heirs and personal representatives. 
  

	7.8	Safe Income 

 Subject to the terms of the Interim Order and
the receipt of all necessary approvals or exemptive relief orders from applicable Governmental Entities, Hummingbird Shareholders will be permitted to effect a “safe income tuck-in” transaction (a “Safe Income
Transaction”) in accordance with applicable Laws to be effective shortly prior to the Effective Date, on the terms and subject to the conditions and limitations described in the holding company participation agreement attached as Schedule D
hereto (the “Participation Amendment”); provided that: (a) no Shareholder will be permitted to effect a Safe Income Transaction unless the terms and conditions of such Safe Income Transaction are satisfactory to Hummingbird and
Parent acting reasonably; (b) draft documentation regarding any Hummingbird Shareholder’s proposed Safe Income Transaction (including with respect to any transfers or deemed dividends) shall be delivered to Hummingbird and Parent no later
than September 18, 2006, and Hummingbird and Parent shall have a reasonable opportunity to review and comment on such draft documentation, 

  

 - 55 - 

 
and all reasonable comments of Hummingbird and Parent shall be reflected in the final documentation executed in respect of such Safe Income Transaction; and
(c) in the event that (i) the terms and conditions of such Safe Income Transaction are not satisfactory to the Director or the Court or (ii) any securities regulatory authority, including any of the Canadian Securities Administrators,
refuses to grant any relief required or, in the opinion of Parent, desirable, in connection with any such Safe Income Transaction (for greater certainty, including exemptive relief from the issuer bid requirements under applicable Canadian
securities laws) or such relief is not granted prior to the date of the Meeting, then the agreement under this Section 7.8 shall be immediately terminated and of no further force or effect and none of Parent, Acquisition Sub or Hummingbird
shall be obligated to consider, facilitate or assist in any alternative or amended form of “safe income” transaction for Hummingbird Shareholders. 
 ARTICLE 8

pursuant to this Section 8.2(1)(h) shall not be available to any party that has breached in any material respect its obligations under this Agreement in any manner that shall have proximately contributed to the occurrence of the failure of the
Effective Time to occur on or before such date; or

conditions under Section 6.2(a), Section 6.2(b)(i), Section 6.3(a) or Section 6.3(b) (the “Specified Conditions”) or to exercise the termination rights under Section 8.2(1)(c) (as it relates to
Section 6.2(a) or Section 6.2(b)(i)) or Section 8.2(l)(d) (the “Specified Termination Rights”) unless Parent or Hummingbird, as the case may be, has delivered a written notice to the other specifying in reasonable
detail all breaches of covenants, agreements or representations and warranties which Parent or Hummingbird, as the case may be, is asserting as the basis for non-fulfilment of the applicable Specified Condition or the exercise of the applicable
Specified Termination Right, as the case may be. If any such notice is delivered, provided that Parent or Hummingbird, as the case may be, is proceeding diligently to cure such matter and such matter is capable of being cured, the other may not
terminate this Agreement until the earlier of the Outside Date and the expiration of a period of 30 days from such notice (and then only if such breach remains uncured). If such notice has been delivered prior to the date of the Special Meeting,
such meeting shall be 

  

 - 57 - 

 
postponed until the expiry of such period. For greater certainty, in the event that such matter is cured within the time period referred to herein, this
Agreement may not be terminated as a result of the cured breach. Also for greater certainty, this Section 8.2(3) does not apply to a Party electing to not consummate the transactions contemplated hereby pursuant to any condition precedent
contained herein other than the Specified Conditions or exercising any termination rights herein other than the Specified Termination Rights. 
  

	8.3	Amendment 

 This Agreement may be amended by
the parties hereto by action taken by or on behalf of their respective boards of directors at any time prior to the Effective Time; provided, however, that, after receipt of approval of Hummingbird Shareholders there shall be made no amendment that
by Law requires further approval by Hummingbird Shareholders at the Meeting without the further approval of such holders. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto. 
  

	8.4	Waiver 

 Any Party may (a) extend the
time for the performance of any of the obligations or acts of the other Party, (b) waive compliance with any of the other Party’s agreements or the fulfillment of any conditions to its own obligations contained herein, or (c) waive
inaccuracies in any of the other Party’s representations or warranties contained herein or in any document delivered by the other Party; provided, however, that any such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such Party and, unless otherwise provided in the written waiver, will be limited to the specific breach or condition waived.

 - 6 - 

	 	 
notwithstanding section 190 of the CBCA, Acquisition Sub and not Hummingbird shall be required to pay fair market value for the Hummingbird Shares held by
holders who duly exercise Dissent Rights. A Shareholder who duly exercises such Dissent Rights and who: 

 (i) is ultimately
entitled to be paid fair value for its Hummingbird Shares shall be deemed to have transferred such Hummingbird Shares to Acquisition Sub on the Effective Date contemporaneously with the event described in Section 2.3(e) in exchange for the fair
value of such Hummingbird Shares; or 
 (ii) is ultimately not entitled, for any reason, to be paid fair value for its Hummingbird Shares
shall be deemed to have participated in the Arrangement on the same basis as a non-dissenting Shareholder. 
  

	 	(b)	In no circumstances shall Parent, Acquisition Sub, Hummingbird or any other Person be required to recognize a Person exercising Dissent Rights unless such Person is a Shareholder of
those Hummingbird Shares in respect of which such rights are sought to be exercised. 

  

	 	(c)	For greater certainty, in no case shall Parent, Acquisition Sub, Hummingbird or any other Person be required to recognize a Dissenting Holder as a Shareholder after the Effective

 ARTICLE 4 
 CERTIFICATES AND PAYMENTS

  

	4.1	Letter of Transmittal 

 At the time of
mailing the Circular or as soon as practicable thereafter, Hummingbird shall forward to each Shareholder and each Optionholder at the address of such holder as it appears on the register maintained by or on behalf of Hummingbird in respect of the
holders of Hummingbird Shares or Hummingbird Options, as the case may be, a letter of transmittal in the case of the holders of Hummingbird Shares and, in the case of Optionholders, instructions for obtaining delivery of the consideration payable to
Optionholders following the Effective Date pursuant to this Plan of Arrangement. 
  

	4.2	Exchange of Certificates for Cash 

  

	 	(a)	 At or before the Effective Time, Acquisition Sub shall deposit the Maximum Cash Amount with the Depositary to be held in escrow until Section 2.3(a) takes
effect. Upon surrender to the Depositary for cancellation of a certificate which immediately prior to the Effective Time represented outstanding Hummingbird Shares, together with a duly completed and executed Letter of Transmittal and such
additional documents and instruments as the Depositary may reasonably require, the Shareholder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such Shareholder as soon as
practicable after the Effective Time, a cheque representing the cash which such 

  

 - 7 - 

	 	 
Shareholder has the right to receive under the Arrangement for such Hummingbird Shares, less any amounts withheld pursuant to Section 4.4, and any
certificate so surrendered shall forthwith be cancelled. The cash deposited with the Depositary shall be held in an interest-bearing account, and any interest earned on such funds shall be for the account of Acquisition Sub.

  

	 	(b)	Until surrendered as contemplated by this Section 4.2, each certificate which immediately prior to the Effective Time represented any Hummingbird Shares shall be deemed after
the Effective Time to represent only the right to receive upon such surrender a cash payment in lieu of such certificate as contemplated in this Section 4.2, less any amounts withheld pursuant to Section 4.4. Any such certificate formerly
representing Hummingbird Shares not duly surrendered on or before the sixth anniversary of the Effective Date shall cease to represent a claim by or interest of any former Shareholder of any kind or nature against or in Hummingbird, Parent or
Acquisition Sub. On such anniversary date, all certificates representing Hummingbird Shares shall be deemed to have been surrendered to Acquisition Sub and cash to which such former holder was entitled, together with any entitlements to dividends,
distributions and interest thereon, shall be deemed to have been surrendered to Hummingbird. 

  

	 	(c)	On or as soon as practicable after the Effective Date, the Depositary shall deliver on behalf of Hummingbird to each Optionholder as reflected on the books and records of
Hummingbird a cheque representing the payment to which such holder is entitled in accordance with Section 2.3(b) of this Plan of Arrangement, against receipt of such documentation as Parent or Hummingbird may reasonably require acknowledging
the transfer and termination of the Hummingbird Options held by such Optionholder. 

  

	 	(d)	Any payment made by way of cheque by the Depositary on behalf of Acquisition Sub or Hummingbird that has not been deposited or has been returned to the Depositary or that otherwise
remains unclaimed, in each case on or before the sixth anniversary of the Effective Date, shall cease to represent a right or claim of any kind or nature and the right of the Shareholder or Optionholder to receive the consideration for Hummingbird
Shares or Hummingbird Options, as the case may be, pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Hummingbird for no consideration. 

  

	4.3	Lost Certificates 

 In the event any
certificate which immediately prior to the Effective Time represented one or more outstanding Hummingbird Shares that were transferred pursuant to Section 2.3 shall have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the Person claiming such certificate to be lost, stolen or destroyed, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, cash deliverable in accordance with such holder’s Letter of Transmittal. When
authorizing such payment in exchange for any lost, stolen or destroyed certificate, the Person to whom such cash is to be delivered shall as a condition precedent to the delivery of such cash, give a bond satisfactory to Hummingbird and the
Depositary in such sum as Hummingbird may direct, or otherwise indemnify Hummingbird in a manner satisfactory to 

  

 - 8 - 

 
Hummingbird, against any claim that may be made against Acquisition Sub and Hummingbird with respect to the certificate alleged to have been lost, stolen or
destroyed. 
  

	4.4	Withholding Rights 

 Hummingbird, Acquisition
Sub, Parent and the Depositary and any affiliate of Hummingbird shall be entitled to deduct and withhold from any consideration otherwise payable to any Shareholder or Optionholder such amounts as Hummingbird, Acquisition Sub, Parent or the
Depositary is required or permitted to deduct and withhold with respect to such payment under the Tax Act, the United States Internal Revenue Code of 1986 or any provision of federal, provincial, state, local or foreign tax law, in each case, as
amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the holder of the Hummingbird Shares or Hummingbird Options in respect of which such deduction and withholding
was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority.

such Taxes have been assessed or reassessed as at the date hereof), and any instalments with respect thereto, costs and expenses (including, without limitation, all legal and other professional fees and disbursements, interest, penalties and amounts

	6.2	Notice of Claim 

 In the event that a party to this Agreement (the
“Indemnified Party”) shall become aware of any claim, proceeding or other matter (a “Claim”) in respect of which another party to this Agreement (the “Indemnifying Party”) agreed to indemnify the
Indemnified Party pursuant to this Agreement, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party. Such notice shall specify whether the Claim arises as a result of a claim by a person against the Indemnified
Party (a “Third Party Claim”) or whether the Claim does not so arise (a “Direct Claim”), and shall also specify with reasonable particularity (to the extent that the information is available) the factual basis for
the Claim and the amount of the Claim, if known. If, through the gross negligence or wilful misconduct of the Indemnified Party, the 

  

 - 15 - 

 
Indemnifying Party does not receive notice of any Claim in time to contest effectively the determination of any liability susceptible of being contested, the
Indemnifying Party shall be entitled to set off against the amount claimed by the Indemnified Party the amount of any Liabilities incurred by the Indemnifying Party resulting from the Indemnified Party’s failure to give such notice on a timely
basis. 
  

	6.3	Direct Claims 

 With respect to any Direct Claim, following receipt
of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have 30 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make
available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If both parties agree at or prior to the

 With respect to any Third Party Claim, the
Indemnified Party shall have the exclusive right, at the expense of the Indemnifying Party, to contest, settle or pay the amount claimed and to retain counsel and other experts or advisors selected by the Indemnified Party in its sole discretion in
connection therewith; provided, however, that the Indemnified Party shall not settle any Third Party Claim without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed; provided, however, that
the Indemnifying Party shall remain liable for the settlement amount even if any such consent is not obtained for any reason. If the Indemnified Party elects to assume such control, the Indemnifying Party shall have the right, at its sole expense,
to participate in the negotiation, settlement or defence of such Third Party Claim. If any Third Party Claim is of a nature such that the Indemnified Party is required by applicable law to make a payment to any person (a “Third Party”)
with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party,
reimburse the Indemnified Party for such payment. If the amount of any liability of the indemnified Party under the Third Party Claim in respect of which such payment was made, as finally determined, is less than the amount that was paid by the
Indemnifying Party to the Indemnified Party, the Indemnified Party shall, forthwith after receipt of the difference from the Third Party, pay the amount of such difference to the Indemnifying Party. 
  

	6.5	Reduction, Set-off, Payment and Co-operation 

 The Indemnifying
Party shall pay to the Indemnified Party all amounts for which the Indemnifying Party is liable pursuant to this Section 6 promptly after the Indemnified Party incurs the Liability in respect of which such liability arises. If such amount is
not so paid, the Indemnified Party may deduct or set-off such amount from any obligation it may have to the Indemnifying Party. The Indemnified Party and the Indemnifying Party shall co-operate fully with each other with respect to Third Party
Claims, and shall keep each other fully advised with 

  

 - 16 - 

 
respect thereto (including supplying copies of all relevant documentation promptly as it becomes available).

affiliated companies, and all such entities’ present and former directors, officers, employees, advisors and agents) a full and final release from any and all Liabilities suffered or incurred as a result of or with respect to or in any way
connected with the transactions contemplated hereby including the computation of “safe income” for purposes of the ITA and any relevant provincial or territorial legislation and any information in that regard provided by any of Parent,

relied upon any statements or representations whatsoever from Parent, Acquisition Sub, Hummingbird or their respective affiliates or advisors. 
 ARTICLE 8

without limitation the calculation of the amount of the Liabilities at any time, every sum of money which is now or which may hereafter from time to time be due or owing to any Creditor by any Debtor (or would have become so due or owing were it not
for the insolvency, bankruptcy, reorganization or winding-up of such Debtor) shall be deemed to be and to continue due and owing to such Creditor until the same shall be actually paid in cash to such Creditor, notwithstanding the insolvency,
bankruptcy, reorganization or winding-up of such Debtor or any other event whatsoever. The Guarantor agrees that, if at any time all or any part of any payment previously applied by any Creditor to any of the Liabilities is or must be rescinded or
returned by such Creditor for any reason whatsoever (including without limitation the insolvency, bankruptcy, reorganization or winding-up of a Debtor), such Liability shall, for the purpose of this guarantee, to the extent that such payment is or
must be rescinded or returned, be deemed to have continued in existence, notwithstanding such application by such Creditor, and this guarantee shall continue to be effective or be reinstated, as the case may be, as to such Liability, all as though
such application had not been made. No assurance, security or payment which may be rescinded or avoided under any law relating to insolvency, bankruptcy, reorganization or winding-up and no release, settlement, discharge or arrangement which may
have been given or made on the faith of any such assurance, security or payment shall prejudice or affect the right of the Creditors to recover from the Guarantor to the full extent of this guarantee as if such assurance, security, payment, release,
settlement, discharge or arrangement had never been granted, given or made. Any such release, settlement, discharge or arrangement shall as between the Creditors and the Guarantor, be deemed to have been given or made upon the express condition that
it shall become and be wholly void and of no effect if the assurance, security or payment on the faith of which it was made or given shall at any time thereafter be rescinded or avoided as aforesaid, to the intent so that the Creditors shall become
and be entitled at any time after any such recission or avoidance to exercise all or any of the rights conferred upon the Creditors hereunder and of all other rights which by virtue and as a consequence of this guarantee the Creditors would have
been entitled to exercise but for such release, settlement, discharge or arrangement. 
 4. Enforcing Rights Against Guarantor: The
Guarantor hereby waives the benefits of division and discussion. Without limiting the foregoing, no Creditor shall be obliged to take any action or to exhaust any recourse against any Debtor, any other person, or any security held at any time by any
Creditor, nor to value any security held by any Creditor, before requiring, or being entitled to, payment from, and to enforce its rights and remedies against, the Guarantor under this guarantee. No Creditor shall be obliged to marshall any assets
in favour of the 

  

 - 3 - 

 
Guarantor. Any third party dealing with any Creditor shall not be concerned to see or inquire as to the validity of any demand under this guarantee.

 5. Guarantee Absolute: 
  

	 	(1)	The liability of the Guarantor hereunder shall be absolute and unconditional and shall not be released, discharged, diminished, limited or in any way affected by any matter, act,
failure to act, or circumstance whatsoever, including without limitation: (a) any lack of enforceability of any agreement between any Creditor and any Debtor or any document provided by any Debtor to any Creditor; (b) any failure on the
part of any Debtor to carry out any rights or obligations under any agreement or document; (c) any change in the name, objects, powers, organization, share capital, constating documents, business, shareholders, directors or management of any
Debtor; (d) any amalgamation, merger or consolidation of any Debtor into or with any other person or entity, or any sale, lease or transfer of all or any of the assets of any Debtor to any other person or entity; (e) any lack or limitation
of power, incapacity or disability on the part of any Debtor or any of its directors, officers, shareholders, partners, employees or agents, or any other irregularity, defect or informality, or any fraud, on the part of any Debtor or any of its
directors, officers, shareholders, employees or agents with respect to any or all of the Liabilities; (f) any impossibility, impracticability, frustration of purpose, illegality, force majeure or act of government or governmental authority;
(g) the insolvency, bankruptcy, reorganization, winding- up or financial condition of any Debtor or any other person at any time; (h) any loss of or in respect of any security held by or on behalf of any Creditor, whether occasioned
through the fault of a Creditor or otherwise; (i) any law, regulation, limitation period or other matter or circumstance which might otherwise constitute a defence available to, or a discharge of, a Debtor with respect to any or all of the
Liabilities; (j) any loss or impairment of any right of the Guarantor to subrogation, reimbursement or contribution, whether or not as a result of any action taken or omitted to be taken by any Creditor; and (k) anything done, omitted to
be done, suffered or permitted by any Creditor in connection with all or any of the Liabilities or otherwise or in connection with any security held by or on behalf of any Creditor (whether relating to the Liabilities or otherwise), or which might
otherwise operate to release, discharge, diminish or limit in any way the liability of, or otherwise provide a defence to, a guarantor or surety. 

  

	 	(2)	 The Creditors may, with respect to all or any of the Liabilities and without releasing, discharging, limiting or otherwise affecting in whole’ or in part the
Guarantor’s liability hereunder: (a) amend, alter or vary any of their agreements with any of the Debtors or any other person; (b) grant time, renewals, extensions, indulgences, releases and discharges to any Debtor or any other
person; (c) increase or reduce the rate of interest on all or any of the Liabilities; (d) alter, compromise, accelerate, extend or change the time or manner for payment by any Debtor of, or by any other person or persons liable to the
Creditors in respect of any or all of the Liabilities; (e) take or abstain from taking security from any Debtor or any other person or from completing or perfecting any security taken; (f) release or add one or more guarantors or sureties,
accept additional or 

  

 - 4 - 

	 	 
substituted security, or release or subordinate any security; (g) accept compromises from any Debtor or any other person; (h) apply all money at
any time received from any Debtor or from any person other than the Guarantor or from any security upon such part of the Liabilities as the Creditors may see fit, and change any such application from time to time in their discretion, or keep such
money in a separate account for such period as the Creditors may determine without application to the Liabilities; and (i) otherwise deal with the Debtors, the Guarantor and all other persons and security as the Creditors may determine. The
Creditors may apply all money at any time received from the Guarantor hereunder upon such part of the Liabilities as the Creditors may see fit, and may change any such application from time to time in their discretion. 

6. Indemnity: If any amount in respect of the Liabilities is not recoverable from the Guarantor hereunder on the basis of a guarantee, then,
notwithstanding any other provision hereof, (a) the Guarantor shall be liable hereunder as principal debtor in respect of the due payment of such amount, and shall pay such amount to Hummingbird for the benefit of the Creditors after demand as
herein provided, and (b) the Guarantor shall indemnify and saves each of the Creditors harmless from and against all losses, costs, damages, expenses, claims and liabilities that such Creditor may suffer or incur in connection with or in
respect of any failure by the applicable Debtor for any reason to pay or perform any such Liability and shall pay the amount of such loss, cost, damage, expense, claim or liability to Hummingbird for the benefit of the applicable Creditor after
written demand for same by Hummingbird. 
 7. Conclusive Statement: Any account settled or stated by or between a Creditor and a
Debtor at any time respecting the Liabilities shall be prima facie evidence that the balance or amount thereof appearing due to the applicable Creditor is so due. 
 8. Stay of Acceleration, etc.: If acceleration of the time for payment, or the liability of a Debtor to make any payment, of any amount specified to be payable by a Debtor in respect of the Liabilities is
stayed, prohibited or otherwise affected upon the insolvency, bankruptcy, reorganization or winding-up of such Debtor or any moratorium affecting the payment of the Liabilities by such Debtor, all such amounts otherwise subject to acceleration or
payment shall nonetheless be deemed for all purposes of this guarantee to be and to become due and payable by such Debtor and shall be payable by the Guarantor hereunder forthwith after demand by Hummingbird. 
 9. Subrogation, etc.: Until the Liabilities have been indefeasibly paid in full, the Guarantor shall not exercise or enforce any right of
subrogation against any Debtor. In case of the insolvency, bankruptcy, reorganization or winding-up of a Debtor (whether voluntary or compulsory) or in the event that a Debtor shall make a bulk sale of any assets or scheme of arrangement with
creditors, all dividends and other payments which may be due or payable to the Guarantor are hereby assigned and transferred to and shall be due and paid to Hummingbird for the benefit of the Creditors on account of the Liabilities, and for such
payment to Hummingbird this shall be a sufficient warrant and authority to any person making the same. The Guarantor shall continue to be liable under this guarantee for any balance of the Liabilities which may be owing to the Creditors by a Debtor,
and in the event of the valuation by the Creditors of any of their security and/or retention thereof by the Creditors in accordance with the Bankruptcy and Insolvency Act (Canada) or any other applicable legislation, such valuation and/or
continuation 

  

 - 5 - 

 
shall not as between the Creditors and the Guarantor, be considered as a purchase of such security, or as payment or satisfaction or reduction of all or any
part of the Liabilities. 
 10. Amounts Owed by Debtors. All present and future indebtedness and liabilities of each of the Debtors to
the Guarantor are, effective from and after the date of any demand under this guarantee, postponed and subordinated to the full and final payment of all Liabilities, and until otherwise agreed in writing by the Creditors, all moneys received by the
Guarantor in respect of any such indebtedness and liabilities at any such time shall be received as mandatary and agent for the Creditors, shall be kept by the Guarantor separate and apart from its other assets, and shall be paid over to Hummingbird
on account of the Liabilities. 
 11. Alteration or Waiver: No alteration or waiver of this guarantee or of any of its terms,
provisions or conditions shall be binding on the Creditors unless made in writing by an authorized officer of Hummingbird. No failure on the part of any Creditor to exercise, and no delay in exercising, any right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right hereunder preclude the other or further exercise thereof or the exercise of any other right. 
 12. Rights Not Exhaustive: All rights, powers and remedies of the Creditors hereunder shall be in addition to all rights, powers and remedies given to the Creditors at law, in equity, under statute, by
agreement or otherwise. All such rights, powers and remedies are cumulative and not alternative and shall not be exhausted by any exercise thereof against the Guarantor or by any number of successive actions until and unless all of the Liabilities
have been paid and each of the Guarantor’s obligations hereunder has been fully performed. This guarantee is in addition to and not in substitution for any security held at any time by any of the Creditors. 
 13. Severability: Any provision of this guarantee which is or is deemed to be void, prohibited or unenforceable in any jurisdiction shall be
severed from this guarantee with respect to such jurisdiction, without in any way invalidating the remaining provisions of this guarantee and without affecting such provision in any other jurisdiction. 
 14. Delivery and Completeness of Guarantee: Upon this guarantee, bearing the signature of the Guarantor, coming into the possession of
Hummingbird, the same shall be deemed to be finally executed and delivered by the Guarantor and shall not be subject to or affected by any promise or condition affecting or limiting the Guarantor’s liability except as set forth herein, and no
statement, representation, agreement or promise on the part of any officer, employee or agent of any Creditor, unless contained herein, forms any part of this guarantee or has induced the making of this guarantee or shall be deemed in any way to
affect the Guarantor’s liability hereunder. This guarantee and the Participation Documents constitute the entire agreement between the Creditors and the Guarantor with respect to the subject matter hereof and cancels and supersedes any prior
understandings and agreements between them with respect thereto. 
 15. Financial Condition: The Guarantor is fully aware of the
financial condition of each of the Debtors, has made all inquiries which the Guarantor feels are necessary and acknowledges that the Guarantor has received no information from any Creditor regarding any Debtor or its financial condition.

immediately, available funds and shall be made without set-off, or counterclaim and without deduction for any Taxes, levies, duties, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever. If at any time any applicable
law, regulation or international agreement requires the Guarantor to make any such deduction or withholding from any such payment, the sum due from the Guarantor with respect to such payment will be increased to the extent necessary to ensure that,
after the making of such deduction or withholding, the Creditors receive a· net sum equal to the sum which they would have received had no
deduction or withholding been required. 
 17. Expenses: The Guarantor shall from time to time forthwith after demand by
Hummingbird pay to Hummingbird all liabilities, costs and expenses (including reasonable legal fees and expenses on a solicitor and own client basis and any sales, goods and services or other similar taxes payable to any governmental authority with
respect to any such liabilities, costs and expenses) incurred by the Creditors in the preservation or enforcement of any of their rights hereunder. 
 18. Interest: The liability of the Guarantor to make any payments under this guarantee will bear interest at a nominal rate per annum equal to the Prime Rate in effect from time to time plus 2%, which rate per annum
will change automatically without notice to the Guarantor as and when the Prime Rate changes. Such interest will be payable by the Guarantor on demand and will be calculated, but not compounded, daily (both before and after judgement) from and
including the date such payment becomes due and payable by the Guarantor under this guarantee to but not including the date of payment. The term “Prime Rate” shall mean the reference rate of interest (however designated) of · for determining interest chargeable by it on Cdn. dollar commercial loans made in Canada. 
 19. Communications: Any notice or communication to be given hereunder may be effectively given by delivering the same at the addresses set

Duggal in the case of Hummingbird. The facsimile number for the Guarantor is · and for Hummingbird is (416) 496- 2207.

this guarantee will extend to and include all indebtedness, liabilities and obligations of the amalgamated body corporate or consolidated person; the term “Debtor”, where used in this guarantee, will extend to and include the amalgamated
