(ii)

that fraction of a fully paid and non-assessable Hawker Common Share as is equal to the Exchange Ratio, subject to the Maximum Share Consideration,

and provided further that in the event the Hawker Average Price is less than $4.75, Hawker shall have the right, but not the obligation, to terminate this Agreement in accordance with Section 11.1(h), which offer shall be made in accordance with this Agreement, the Act and Securities Laws and be subject to the conditions set forth in Schedule A hereto (the “Offer”, which term shall include any amendments to, or extensions of, such Offer, including, without limitation, increasing the consideration, removing or waiving any condition or extending the date by which Zorin Shares may be tendered). The Offer price set forth above in this Section 2.1(a) is based on there being a total of 18,558,000 Zorin Shares outstanding at the Expiry Time and, to the extent the actual number of Zorin Shares outstanding at such time exceeds 18,558,000, the Offer price as

set forth above in this Section 2.1(a) shall be reduced proportionately. Hawker and Zorin shall cooperate in making on a timely basis any filings with respect to the Offer, including amendments thereafter on a timely basis as required by Securities Laws. Hawker shall provide Zorin with a draft copy of the Offer Documents prior to mailing for its review and comment.

(b)

Zorin acknowledges and agrees that Hawker may make the Offer itself, or through one or more direct or indirect wholly-owned subsidiaries, or any combination thereof (which, for the purposes hereof, may include a partnership, all of the partners of which are direct or indirect subsidiaries of Hawker or any combination thereof). In the event that any such subsidiary makes the Offer, the term “Hawker” as used herein shall include all of such subsidiaries, but Hawker shall continue to be directly liable to Zorin as principal obligor for any default in performance by any such subsidiary.

(c)

The Offer shall expire at the Initial Expiry Time, except that the Offer may be extended, at the sole discretion of Hawker, if the conditions thereto set forth in Schedule A hereto are not satisfied on the date and time at which the Offer expires. In addition, in the event that any appropriate regulatory approval is not obtained prior to the time the Offer is scheduled to terminate, unless such approval has been denied, Hawker agrees that it will extend the Offer for not less than two additional successive 10 day periods if, upon the expiry of the first such extension, the appropriate regulatory approval has not been obtained.

Subject to the satisfaction or waiver of the conditions set forth in Schedule A hereto, Hawker shall within three Business Days accept for payment and pay for all Zorin Shares validly tendered (and not properly withdrawn) pursuant to the Offer. Each of Hawker and Zorin shall use all commercially reasonable efforts to consummate the Offer, subject to the terms and conditions thereof.

(d)

It is agreed that Hawker may, in its sole discretion: (i) waive, in whole or part, any term or condition of the Offer for its benefit at any time and from time to time provided that if Hawker takes up and pays for any Zorin Shares it shall acquire not less than the Minimum Required Shares; and (ii) amend any term or condition of the Offer, provided that Hawker shall not decrease the aggregate value of the consideration to be paid for each Zorin Share (subject to Section 2.1(a)) or modify or impose additional conditions to the Offer in a manner that is materially adverse to the holders of Zorin Shares provided that, after Hawker reduces the Minimum Condition, Hawker extends the Offer by a 10 day period. Hawker shall provide a draft of any proposed amendment, modification or change to the Offer to Zorin.

(e)

Hawker will instruct the depositary under the Offer to advise Zorin from time to time, if requested by Zorin and in such manner as Zorin may reasonably request, as to the number of Zorin Shares that have been tendered (and not withdrawn) under the Offer.

(f)

Hawker’s obligation to make the Offer as set forth in Section 2.1(a) is conditional upon the execution and delivery to Hawker, concurrently with the execution of this Agreement, of pre-tender agreements referred to in Section 2.2(b).

the board of directors of Zorin shall have withdrawn its positive recommendation of the Offer;

(ii)

any of the representations or warranties of Zorin contained herein shall not be true and correct in all material respects or Zorin shall not have complied in all material respects with each of its covenants set out herein;

(iii)

a Material Adverse Change shall have occurred, or a person shall have commenced a bona fide action for injunctive relief against the performance of this Agreement or the completion of the Offer, or another event shall have occurred or circumstances shall exist which would make it impossible or highly unlikely to satisfy one or more of the conditions of the Offer set forth in Schedule A hereto; or

(A)

all of the representations and warranties of Zorin contained herein are true and correct in all material respects;

(B)

Zorin has complied in all material respects with each of its covenants set out herein; and

The foregoing conditions in (f) and (g) are for the sole benefit of Hawker and may be waived by Hawker at any time.

(a)

Zorin hereby consents to the Offer as set forth in Section 2.1 and confirms that its Board of Directors has unanimously approved the Offer and the entering into of this Agreement, has determined that the Offer is fair, from a financial point of view, to the holders of Zorin Shares and has unanimously resolved to recommend acceptance of the Offer by the holders of Zorin Shares, subject to Section 8.3.

Zorin represents that all of its directors and officers, holding in aggregate approximately 60% of the issued and outstanding Zorin Shares have agreed to execute pre-tender agreements (in the form of the agreement attached hereto as Schedule B) and agrees to deliver such agreements concurrently with the execution of this Agreement duly executed by each of its directors and officers.

(c)

Zorin represents that it has obtained advice from Waterous & Co. that the consideration to be offered to Zorin shareholders pursuant to the Offer is fair to holders of Zorin Shares from a financial point of view and that Waterous & Co. will provide a written opinion to such effect before the mailing of the Directors’ Circular. The fairness opinion will be attached to or referred to in the Directors’ Circular referred to in Section 2.2(a).

(a)

Hawker shall file or cause to be filed with the appropriate Securities Authorities an Offer to Purchase and Take-Over Bid Circular and the related Letter of Transmittal and Notice of Guaranteed Delivery pursuant to which the Offer will be made (collectively, the “Offer Documents”). The Offer Documents, when filed with Securities Authorities and when mailed to holders of Zorin Shares, shall contain (or shall be amended in a timely manner to contain) all information which is required to be included therein in accordance with any applicable Canadian provincial Securities Laws.

(b)

Zorin agrees to provide such assistance as Hawker or its agents may reasonably request in connection with communicating the Offer and any amendments and supplements thereto to the holders of the Zorin Shares and to such other persons as are entitled to receive the Offer under Securities Laws, including providing lists and updated or supplemental lists of the holders of Zorin Shares, Zorin Options and Zorin Warrants and mailing labels with respect to all such holders of securities as soon as possible after the date of this Agreement but in any event no later than the close of business in Calgary on January 20, 2004 (and shall similarly provide to Hawker by not later than close of business in Calgary on

January 23, 2004, a geographic breakdown of beneficial holders of Zorin Shares from ADP Canada or a similar service provider indicating the number of Zorin Shares beneficially held within Canada, by province, and elsewhere) and updates or supplements thereto from time to time as may be requested by Hawker.

(a)

The Zorin Board of Directors shall not, prior to completion of the Offer, grant additional Zorin Options pursuant to the Stock Option Plan or issue additional Zorin Warrants or adjust or modify the exercise price of any outstanding Zorin Options or Zorin Warrants.

(b)

Zorin will pay to each holder of Zorin Options the positive difference, if any, that results from subtracting from the ascribed purchase price for the Zorin Shares under the Offer the exercise price of outstanding Zorin Options held by such holder, immediately after the Take-up Date in exchange for the termination of all Zorin Options and Zorin Warrants held by such person provided that all holders of Zorin Options and Zorin Warrants agree to surrender all Zorin Options and Zorin Warrants to Zorin for cancellation for no further consideration effective immediately prior to the Take-up Date.

(c)

Zorin agrees to use its reasonable commercial efforts and represents that the directors have unanimously determined to use their respective reasonable commercial efforts to encourage and facilitate all persons holding Zorin Options and Zorin Warrants to agree with Zorin to an arrangement described in Section 2.4(b) prior to the Expiry Time of the Offer.

The Exchange Ratio shall be proportionately adjusted to reflect fully the effect of (a) any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Hawker Common Shares), reorganization, recapitalization or other like change with respect to Hawker Common Shares, and (b) any extraordinary dividend or distribution with respect to Hawker Common Shares (other than a dividend or distribution referenced in (a)); provided that the foregoing adjustments shall only be made if the record date for the stock split, reverse split, stock dividend, reorganization, recapitalization, other like change or extraordinary dividend or distribution referred to in (a) and (b) occurs after the date of this Agreement and prior to the Effective Time.

(a)

Each of Hawker and Zorin shall advise, consult and cooperate with the other party prior to issuing, or permitting any of its subsidiaries, directors, officers,

employees or agents to issue any press release or other written statement to the press with respect to this Agreement or the transactions contemplated hereby. Hawker and Zorin shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable law or by obligations pursuant to any listing agreement with a stock exchange and only after using its reasonable commercial best efforts to consult the other party taking into account the time constraints to which it is subject as a result of such law or obligation.

(b)

Zorin and Hawker agree that a news release shall be issued immediately following the execution of this Agreement.

If Hawker takes up and pays for Zorin Shares pursuant to the terms of the Offer, and thereby acquires at least the Minimum Required Shares, Hawker agrees to use all commercially reasonable efforts to acquire, and Zorin agrees to use all commercially reasonable efforts to assist Hawker in acquiring, the balance of the Zorin Shares by way of compulsory acquisition or a statutory arrangement, amalgamation, merger, reorganization, consolidation, recapitalization or other type of acquisition transaction or transactions (“Second Stage Transaction”) carried out for consideration per Zorin Share not less than the consideration paid pursuant to the Offer (it being understood that Hawker shall be under no obligation to pay more than that amount). Nothing herein shall be construed to prevent Hawker from acquiring, directly or indirectly, additional Zorin Shares in privately negotiated transactions, in another take-over bid, tender or exchange offer, or otherwise in accordance with Securities Laws (including by way of compulsory acquisition) following completion of the Offer.

Without limiting Section 4.1, Zorin agrees that if Hawker is required to effect a Second Stage Transaction which requires approval of Zorin’s shareholders in a meeting of Zorin’s shareholders, Zorin shall take all action necessary in accordance with Securities Laws, other applicable Canadian laws and the Zorin Governing Documents to duly call, give notice of, convene and hold a meeting of its shareholders as promptly as practicable to consider and vote upon the action proposed by Hawker. In the event of such a meeting or meetings, Zorin shall use all commercially reasonable efforts to mail to its shareholders an Information Circular with respect to the meeting of Zorin’s shareholders. The term “Information Circular” shall mean such proxy or other required informational statement or circular, as the case may be, and all related materials at the time required to be mailed to Zorin’s shareholders and all amendments or supplements thereto, if any. Hawker and Zorin each shall use all commercially reasonable efforts to obtain and furnish the information required to be included in any Information Circular. The information provided and to be provided by Hawker and Zorin for use in the Information Circular, on both the date the Information Circular is first mailed to Zorin’s shareholders and on

the date any such meeting is held, shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of law. Hawker and Zorin each agree to correct promptly any such information provided by it for use in any Information Circular which shall have become false or misleading.

(a)

Neither the execution and delivery of this Agreement by Hawker, the consummation by it of the transactions contemplated hereby nor compliance by it with any of the provisions hereof will: (i) violate, conflict with, or result in breach of any provision of, require any consent, approval or notice under, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) or result in a right of termination or acceleration under, or result in a creation of any lien, security interest, charge or encumbrance upon any of the properties or assets of Hawker or any of its subsidiaries under, any of the terms, conditions or provisions of (x) the charter or bylaws of Hawker or (y) any material note, bond, mortgage, indenture, loan agreement, deed of trust, agreement, lien, contract or other instrument or obligation to which Hawker or any of its subsidiaries is a party or to which any of them, or any of their respective

properties or assets, may be subject or by which Hawker or any of its subsidiaries is bound; or (ii) subject to compliance with the statutes and regulations referred to in Section 5.3(b), violate any judgment, ruling, order, writ, injunction, determination, award, decree, statute, ordinance, rule or regulation applicable to Hawker or any of its subsidiaries (except, in the case of each of clauses (i) and (ii) above, for such violations, conflicts, breaches, defaults, terminations which, or any consents, approvals or notices which if not given or received, would not have any material adverse effect on the business, operations or financial condition of Hawker and its subsidiaries taken as a whole or on the ability of Hawker to consummate the transactions contemplated hereby).

(b)

Other than in connection with or in compliance with the provisions of Securities Laws, (i) there is no legal impediment to Hawker’s consummation of the transactions contemplated by this Agreement and (ii) no filing or registration with, or authorization, consent or approval of, any domestic or foreign public body or authority is necessary by Hawker in connection with the making or the consummation of the Offer, except for such filings or registrations which, if not made, or for such authorizations, consents or approvals, which, if not received, would not have a material adverse effect on the ability of Hawker to consummate the transactions contemplated hereby.

For the purposes of Section 8.2(b), an announcement by the Board of Directors of Zorin that it does not have all the information necessary to properly evaluate the Take-over Proposal and accordingly is reaffirming and maintaining its recommendation of the Offer pending receipt and analysis of additional information shall not constitute an event within the ambit of Section 8.2(b)

hereof or trigger any obligations to make the payment contemplated by this Section, provided that the Board of Directors of Zorin, not less than five days before the Expiry Time of the Offer, publicly reaffirms and maintains its recommendation of the Offer as set forth in Section 2.2(a) to holders of Zorin Shares without the foregoing qualification in respect of receipt and analysis of additional information relating to the Take-over Proposal.

Zorin shall immediately cease and cause to be terminated any existing solicitation, initiation, encouragement, activity, discussion, negotiation or proceeding with any parties conducted heretofore by Zorin, any of its subsidiaries or their officers, directors, employees, financial advisors, representatives and agents (“Representatives”) with respect to a Take-over Proposal (as defined herein) whether or not initiated by Zorin and in connection therewith, Zorin shall not release any third party from any confidentiality or standstill agreement to which Zorin and such third party is a party or amend any of the foregoing and shall exercise all rights to require the return of information regarding Zorin. From and after the date hereof, Zorin and its subsidiaries will not, and will not authorize or permit any of their Representatives to, directly or indirectly, solicit, initiate or encourage (including by way of furnishing information) or participate in or take any other action to facilitate any inquiries or the making of any proposal which constitutes or may reasonably be expected to lead to a Take-over Proposal from any person, or engage in any discussion, negotiations or inquiries relating thereto or accept any Take-over Proposal; provided, however, that Zorin may: (i) engage in discussions or negotiations with a third party who (without any solicitation, initiation or encouragement, directly or indirectly, by Zorin, any of its subsidiaries or the Representatives after the date hereof) seeks to initiate such discussions or negotiations and may furnish such third party information concerning Zorin and its business, properties and assets which has previously been provided to Hawker if, and only to the extent that: (A) the third party has first made a bona fide written Take-over Proposal that is financially superior to the Offer (as determined in good faith in each case by Zorin’s Board of Directors after receiving the advice of its financial advisors) (a “Superior Proposal”) and Zorin’s Board of Directors has concluded in good faith, after considering applicable law and receiving the advice of outside counsel that such action is required by the Zorin Board of Directors to comply with fiduciary duties under applicable law; (B) prior to furnishing such information to or entering into discussions or negotiations with such person or entity, Zorin receives from such person or entity an executed confidentiality agreement having confidentiality and standstill terms substantially similar to those contained in the Confidentiality Agreement; (C) Zorin immediately provides to Hawker any information provided to any such person or entity if not previously provided to Hawker; (ii) comply with applicable Securities Laws relating to the provision of directors’ circulars, and make appropriate disclosure with respect thereto to Zorin’s shareholders; and (iii) accept, recommend, approve or implement a Superior Proposal contemplated in clause (i)(A), but only (in the case of this clause (iii)) if prior to such acceptance, recommendation, approval or implementation, Zorin’s Board of Directors shall have concluded in good faith, after considering provisions of applicable law and after giving effect to all proposals to adjust the terms and conditions of this Agreement and the Offer which may be offered by Hawker during the 48 hour notice period set forth below, that such action is required by the Zorin Board of Directors to comply with fiduciary duties under applicable law and Zorin terminates this Agreement in

accordance with Sections 8.2 and 11.1(f) and concurrently therewith has paid the fees payable thereunder. Zorin shall give Hawker orally and in writing at least 48 hours advance notice of any decision by the Board of Zorin to accept, recommend, approve or implement a Superior Proposal. Such notice shall include the principal business terms and conditions of the Superior Proposal and the general attributes of any non-cash consideration including the identity of the party making the Superior Proposal. In addition Zorin shall, and shall cause its respective financial and legal advisors to, negotiate in good faith with Hawker to make such adjustments in the terms and conditions of this Agreement and the Offer as would enable Zorin to proceed with the Offer as amended rather than the Superior Proposal. In the event Hawker proposes to amend this Agreement and the Offer to provide substantially equivalent or superior value to that provided under the Superior Proposal within the 48 hour period specified in this Section 8.3, then Zorin shall not enter into any agreement regarding the Superior Proposal.

The Board of Directors of Zorin immediately following the acquisition by Hawker of more than 50% of the outstanding Zorin Shares pursuant to the Offer shall be reconstituted through resignations of all existing Zorin directors and the appointment of Hawker nominees in their stead. Zorin shall, in accordance with the foregoing and subject to the provisions of the Act, assist Hawker to secure the resignations of all Zorin directors to be effective at such time as may be required by Hawker and to use its best efforts to cause the election of the Hawker nominees to fill the vacancies so created in order to effect the foregoing without the necessity of a shareholder meeting.

Zorin shall, to the extent reasonable, cooperate with Hawker in structuring the acquisition by Hawker of Zorin in a tax efficient manner.

Zorin shall make available to Hawker, and consents to the use of, all financial statements and other information of Zorin which may be required to be disclosed in the Offer Documents or in other Hawker documents. Such financial statements shall be prepared in accordance with Canadian GAAP. If required by applicable law, such financial statements shall be audited by Zorin’s auditors. Zorin shall use its best efforts to have its auditors, to the extent required under applicable law, provide their consent to the use of their report and the use of their name in connection with any disclosure by Hawker of such financial statements. Hawker agrees to reimburse Zorin for its reasonable third party expenses in connection with complying with this Section 8.6.

Hawker covenants and agrees that at all times when the Offer is outstanding, Hawker shall not take any action, or fail to take any action, which would or could reasonably be expected to result in the representations and warranties set out in Article 5 being untrue in any material respect at any time while the Offer is outstanding.

Hawker covenants and agrees that, from and including the date hereof until the termination of this Agreement, unless Zorin agrees otherwise in writing:

(a)

Hawker shall use its reasonable commercial efforts to consummate the Offer subject only to the terms and conditions hereof;

(b)

Hawker shall use its reasonable commercial efforts to obtain all of the regulatory approvals, waivers and consents set out in paragraph (b) of Schedule A; and

(c)

Hawker shall honour all employment agreements, severance agreements and other arrangements disclosed in Schedule C if it acquires any Zorin Shares pursuant to the Offer. Hawker acknowledges that Zorin shall hold the benefits of this section in trust for the benefit of such employees and Hawker shall not take any action or permit any of its subsidiaries to take any action that would render, or may reasonably be expected to render, any representation or warranty made by it in this Agreement untrue in any material respect at any time prior to expiry of the Offer or termination of this Agreement, whichever first occurs.

Hawker and Zorin shall, as promptly as practicable hereafter, prepare and file any filings required under any Securities Law or any other applicable law relating to the transactions contemplated herein.

Subject to the terms and conditions herein provided and to fiduciary obligations under applicable law as advised by counsel in writing, each of the parties hereto agrees to use all commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement and to cooperate with each other in connection with the foregoing, including using commercially reasonable efforts: (i) to obtain all

necessary waivers, consents and approvals from other parties to material agreements, leases and other contracts (including, without limitation, the agreement of any persons as may be required pursuant to any agreement, arrangement or understanding relating to Zorin’s operations); (ii) to obtain all necessary consents, approvals and authorizations as are required to be obtained under any federal, provincial or foreign law or regulations; (iii) to defend all lawsuits or other legal proceedings challenging this Agreement or the consummation of the transactions contemplated hereby; (iv) to cause to be lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby; (v) to effect all necessary registrations and other filings and submissions of information requested by governmental authorities; and (vi) to fulfill all conditions and satisfy all provisions of this Agreement and the Offer. For purposes of this Agreement, the obligation to use “commercially reasonable efforts” to obtain waivers, consents, approvals and authorizations to loan agreements, leases and other contracts or under laws or regulation shall not include any obligation to agree to a materially adverse modification of the terms of such documents or to prepay or incur additional material obligations.

This Agreement, other than the provisions set forth in Sections 8.2, 11.2, 12.3 and 12.8, may be terminated by written notice promptly given to the other party hereto, at any time prior to the time Hawker first takes up and pays for Zorin Shares under the Offer:

(b)

by Zorin, if Hawker has not mailed the Offer Documents to holders of Zorin Shares on or before midnight (Calgary time) on February 4, 2004 (provided that if the Offer Documents are required to be translated, such date shall be extended to February 11, 2004); or

(c)

by Hawker, if the conditions to the Offer have not been satisfied or waived by Hawker on or before the Expiry Time (after having extended the Offer as required pursuant to this Agreement); or

(d)

by either Hawker or Zorin, if Hawker has not taken up and paid for the Zorin Shares deposited under the Offer on or before the date which is 90 days, or if a Take-over Proposal is publicly announced, proposed, offered or made to Zorin’s shareholders, 180 days, following the day of mailing of the Offer Documents; or

(e)

by either Hawker or Zorin, if the Offer terminates or expires at the Expiry Time without Hawker taking up and paying for any of the Zorin Shares as a result of the failure of any condition to the Offer to be satisfied or waived unless the failure of such condition shall be due to the failure of the party seeking to terminate this

Agreement to perform the obligations required to be performed by it under this Agreement; or

(f)

by either Hawker or Zorin, if the fee referred to in Section 8.2 becomes payable and payment is made to Hawker; or

(g)

by either Hawker or Zorin, if there has been a misrepresentation, breach or nonperformance by the other party of any representation, warranty (without reference to any qualification as to materiality in such representation and warranty) or covenant contained in this Agreement which would have or would reasonably be expected to have a material adverse effect on the party seeking to terminate, provided the breaching party has been given notice of and 2 Business Days to cure any such misrepresentation, breach or non-performance; or

(h)

by Hawker, if the Hawker Average Price is less than $4.7500 and provided that Hawker shall, upon the exercise of the termination right provided by this Section 11.1(h) and in any event within one Business Day, pay to Zorin the amount of $375,000. Such payment shall be made in immediately available funds to an account designated by Zorin. On the date on which Hawker exercises the termination right provided by this Section 11.1(h), Hawker shall be deemed to hold such amount in trust for Zorin. Any such payment by Hawker shall be without prejudice to the rights or remedies available to Zorin upon the breach of any provision of this Agreement by Hawker.

In the event of the termination of this Agreement as provided in Section 11.1, this Agreement shall forthwith have no further force or effect and there shall be no obligation on the part of Hawker or Zorin hereunder except as set forth in Section 8.2 (provided that the right of payment (in the case of Section 8.2(e), being the public announcement or commencement of such Take-over Proposal) arose prior to the termination of this Agreement), Section 11.1 (with respect to the right of payment of Zorin if Hawker exercises its right to terminate the Agreement pursuant to Section 11.1(h)), Section 12.3, Section 12.8 (insofar as it relates to the reimbursement of expenses) and this Section 11.2, which provisions shall survive the termination of this Agreement. Nothing herein shall relieve any party from liability for any breach of this Agreement.

This Agreement may be amended by mutual agreement between the parties hereto. This Agreement may not be amended except by an instrument in writing signed by the appropriate officers on behalf of each of the parties hereto.

Hawker, on the one hand, and Zorin, on the other hand, may (i) extend the time for the performance of any of the obligations or other acts of the other, (ii) waive compliance with any of the other’s agreements or the fulfilment of any conditions to its own obligations contained herein or (iii) waive inaccuracies in any of the other’s representations or warranties contained herein or in any document delivered by the other party hereto; 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.

All notices and other communications given or made pursuant hereto shall be in writing and shall be deemed to have been duly given or made as of the date delivered or sent if delivered personally or sent by cable, telegram, telecopier or telex or sent by prepaid overnight carrier to the parties at the following addresses (or at such other addresses as shall be specified by the parties by like notice):

If Hawker takes up and pays for Zorin Shares pursuant to the Offer, Zorin shall, provided Zorin is able to obtain the same at a cost not exceeding 150% of the annual premium of Zorin’s current directors’ and officers’ insurance policy, obtain and pay for directors’ and officers’ liability insurance on a “trailing” or “run-off” basis for Zorin’s current and former directors and officers (whether such insurance is maintained independently of or included under Hawker’s directors and officers insurance policy), covering claims made prior to or within six years from the date that the director or officer resigns or is removed as a director or officer of Zorin. Coverage of such directors and officers insurance should be substantially equivalent in scope and coverage to that provided by Zorin’s current directors and officers insurance policy.

Hawker agrees that, if it acquires the Minimum Required Shares under the Offer, it shall cause each of Zorin and its subsidiaries to fulfill its obligations pursuant to indemnities provided or available to past and present officers and directors of Zorin and its subsidiaries pursuant to the provisions of the articles, bylaws or similar constating documents of Zorin and its subsidiaries, applicable corporate legislation and any written indemnity agreements between any of Zorin or its subsidiaries and its past and present directors and officers in the forms provided to Hawker.

Except as provided in Section 8.2 and 8.6, all fees, costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such cost or expense, whether or not the Offer is consummated.

With respect to the Offer, Zorin hereby consents to the Offer and Hawker is hereby released from any of the restrictions set forth in Sections 1 and 2 (to the extent required for Hawker to make the Offer and prepare the Offer Documents), 5 and 9 of the Confidentiality Agreement.

The representations and warranties of Hawker and Zorin contained in this Agreement shall not survive the completion of the Offer and shall expire and be terminated at the earlier of the Effective Time and the date on which this Agreement is terminated in accordance with its terms.

Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law. Any provision of this Agreement that is invalid or unenforceable in any jurisdiction shall be ineffective to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the remaining provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Nothing in this Section 12.12 shall be considered or interpreted or intended to derogate from the requirement of any person to pay taxes or withholdings in accordance with or in compliance with the Income Tax Act (Canada) (including but not limited to section 116 of the Income Tax Act (Canada)).
