THE OFFER

2.1 COVENANTS

(a) Timing –Forthwith after the execution of this Agreement, the Offeror shall make an offer (together with any amendments thereto or extensions thereof, the “Share

- 17 -

Offer”) on the terms summarized in Schedule A hereto for 100% of the Company’s issued and outstanding Class A Shares, including the Class A Shares issued in connection with the Principal Shareholder Transaction described in Section 7.14(c) of this Agreement, and any Class A Shares which may become issued and outstanding prior to the expiry of the Share Offer pursuant to the exercise of currently outstanding Stock Options, for consideration consisting of $1.6553 cash per Class A Share, for an aggregate of $45,690,536 for all Class A Shares issued and outstanding as of the date hereof, subject to adjustment in accordance with Section 2.1(e), provided that ten percent (10%) of the cash payment due to each Shareholder shall be deposited by the Offeror in the Escrow Fund in accordance with Section 9.3 of this Agreement.

(b) Estimated Debt Statement – The Company shall deliver to the Offeror an Estimated Debt Statement on or before the fifth (5th) Business Day immediately prior to the Closing Date. The Estimated Debt Statement will be prepared in good faith in accordance with GAAP applied in a manner consistent with and using the same accounting principles, practices, methodologies, procedures and policies, with consistent classifications, judgments and estimation methodologies used by the Company in the preparation of the Financial Statements (the “Accounting Principles”), and shall be subject to the review and reasonable approval of the Offeror (it being understood and agreed that any failure of the Offeror to dispute any item or aspect of the Estimated Debt Statement shall not preclude the Offeror from exercising any other rights with respect to any aspects of any adjustments under this Agreement).

(c) Closing Date Balance Sheet – Not later than 45 Business Days after the Closing Date, the Offeror will prepare and deliver or cause to be prepared and delivered to the Shareholders’ Agents a balance sheet of the Company as at the Closing Date (the “Closing Date Balance Sheet”). The Closing Date Balance Sheet will include final calculations of the Current Assets, Current Liabilities, Net Working Capital and Debt. The Accounting Principles used to prepare the Estimated Debt Statement

- 18 -

shall be consistently applied in the preparation of the Closing Date Balance Sheet. The Shareholders’ Agents may notify the Offeror that they accept or dispute the Closing Date Balance Sheet at any time within 20 Business Days after receiving it, but the Shareholders’ Agents will be deemed to have accepted the Closing Date Balance Sheet on the 21^st Business Day after receipt unless the Shareholders’ Agents deliver a written notice (the “Balance Sheet Dispute Notice”) to the Offeror of a dispute (a “Balance Sheet Dispute”) on a Business Day prior to that 21^st Business Day. On the date of the Shareholders’ Agents deemed acceptance, or any earlier date upon which the Offeror receives notice of the Shareholders’ Agents acceptance, the Closing Date Balance Sheet will be conclusive and binding on the Offeror and the Former Company Shareholders.

(d) Disputes – The Balance Sheet Dispute Notice must set out, with reasonable specificity, the reasons for the Balance Sheet Dispute, the amount in dispute, and reasonable details of the calculation of those amounts. The Offeror and the Shareholders’ Agents will attempt, in good faith, to resolve the Balance Sheet Dispute within 10 Business Days after the Offeror’s receipt of the Balance Sheet Dispute Notice. Any Balance Sheet Dispute not resolved by the Offeror and the Shareholders’ Agents within that period will be submitted to a senior partner of the accounting firm of PricewaterhouseCoopers LLP in Canada (or, in the event that PricewaterhouseCoopers LLP is unable or unwilling to act in such capacity, to a senior partner of another accounting firm mutually agreed to by the Offeror and the Shareholders’ Agents), whose fees and expenses will be assessed to each party (but in the case of assessment of fees and expenses to the Shareholders’ Agents, paid for from the Escrow Fund) in the same proportion as the aggregate dollar amount of the Balance Sheet Dispute that is unsuccessfully disputed by such party (as finally determined by such accounting firm) bears to the aggregate dollar amount of the entire Balance Sheet Dispute submitted to such accounting firm, and who will render a determination regarding the Balance Sheet Dispute acting as an expert, and not an arbitrator, within 45 Business Days after referral of the Balance Sheet Dispute to such accounting firm, which determination shall be in accordance with the terms of this Agreement and in writing and shall set forth,

- 19 -

in reasonable detail, the basis therefor. The determination of such accounting firm regarding the Balance Sheet Dispute will, absent manifest error, be final and binding upon the Offeror and the Former Company Shareholders, with no right of appeal or judicial review on any grounds.

(e) Determination of Purchase Price

(i) The amount of the Offer Price paid on the Closing Date will be decreased by the amount of Estimated Debt, if any, and the Offer Price on a per share basis shall be adjusted accordingly.

(ii) On the second Business Day following the date on which the parties agree to the Closing Date Balance Sheet, or, if there is a Balance Sheet Dispute, on the second Business Day following the date on which a determination of a Balance Sheet Dispute is made pursuant to Section 2.1(d), the Offer Price will be adjusted as follows:

(A) if the sum of (1) Net Working Capital as determined from the Closing Date Balance Sheet minus the Target Net Working Capital (provided, however, that if the absolute value of such amount is greater than $250,000, such difference shall be considered to be positive or negative $250,000, as the case may be) plus (2) the Estimated Debt minus the Debt as determined from the Closing Date Balance Sheet is an amount greater than zero (the “Net Positive Purchase Price Adjustment Amount”), then (x) the Offer Price will be increased by the Net Positive Purchase Price Adjustment Amount, and (y) the Offeror will pay the Net Positive Purchase Price Adjustment Amount to the Shareholders’ Agents on behalf of the Former Company Shareholders; or

- 20 -

(B) if the sum of (1) the Net Working Capital as determined from the Closing Date Balance Sheet minus the Target Net Working Capital (provided, however, that if the absolute value of such amount is greater than $250,000, such difference shall be considered to be positive or negative $250,000, as the case may be) plus (2) the Estimated Debt minus the Debt as determined from the Closing Date Balance Sheet is an amount less than zero (the absolute value of such amount, the “Net Negative Purchase Price Adjustment Amount”), then (x) the Offer Price will be decreased by the Net Negative Purchase Price Adjustment Amount, (y) the Net Negative Purchase Price Adjustment Amount shall be paid to the Offeror out of the Escrow Fund and (z) the Shareholders’ Agents and the Offeror shall deliver a joint direction instructing the Escrow Agent to effect such payment out of the Escrow Fund; or

(C) if the sum of (1) Net Working Capital as calculated on the basis of the Closing Date Balance Sheet minus the Target Net Working Capital (provided, however, that if the absolute value of such amount is greater than $250,000, such difference shall be considered to be positive or negative $250,000, as the case may be) plus (2) the Estimated Debt minus the Debt as determined from the Closing Date Balance Sheet is equal to zero, then the Offer Price will not be adjusted pursuant to this Section 2.1(e)(ii).

2.2 OPTION PAYMENT

Notwithstanding anything to the contrary contained in this Article 9, the Purchaser Indemnitees may not receive any amounts from the Escrow Funds for claims for indemnification under Section 9.2(a)(i), unless (i) Damages amount to at least $10,000 per incident; and (ii) the aggregate amount of all of the Purchaser Indemnitees’ Damages which would otherwise be recoverable under Section 9.2(a)(i) exceeds two hundred fifty thousand dollars ($250,000), in which case the Purchaser Indemnitees shall receive indemnity from the Escrow Funds for the full amount of the Damages; provided that, for the avoidance of doubt, this limitation shall not apply to Damages arising out of (a) any breaches of any Fundamental Representations, (b) any Pre-Closing Tax Liability, (c) any breaches of the representations and warranties made by the Company in Section 5.11, 5.14, 5.17 or 5.18, or (d) any breaches under Section 9.2(a)(ii).

9.5 ESCROW PERIOD

The escrow period shall terminate on the Extended Termination Date; provided, further, that the portion of the Escrow Funds which is necessary to satisfy any unsatisfied or disputed claims for Damages specified in any Officer’s Certificate delivered to the Escrow Agent prior to the Extended Termination Date with respect to facts and circumstances existing prior to the Extended Termination Date shall remain as Escrow Funds until such claims have been finally resolved in accordance with the terms of this Agreement.

9.6 CLAIM NOTICES

Any party seeking indemnification under this Article 9 (an “Indemnified Party”) shall promptly give the party from whom indemnification is being sought (such notified party, the “Responsible Party”) notice of any matter which such Indemnified Party has determined has given or could

- 87 -

give rise to a right of indemnification under this Article 9 (a “Claim Notice”), within thirty (30) days of such determination:

(a) stating that the Indemnified Party has incurred, paid, accrued or otherwise suffered or knows of facts giving rise to a reasonable probability that it will have to incur, pay, accrue or otherwise suffer, any Damages in an aggregate stated amount, to the extent then known by the Indemnified Party, with respect to which the Indemnified Party is entitled to in an indemnification payment under this Article 9; and

(b) specifying in reasonable detail, to the extent known by the Indemnified Party, the individual items of Damages included in the amount so stated, the date each such item was incurred, paid or accrued, or the basis for such anticipated liability, and the specific nature of the breach to which such item is related (it being agreed that the failure to specify any provision of this Agreement in such Claim Notice shall not preclude the Indemnified Party from asserting that there has been a breach of, or failure to perform, such provision);

provided, however, that the failure to so notify a Responsible Party shall not relieve such Responsible Party of its obligations hereunder, except to the extent that such Responsible Party is materially prejudiced thereby. With respect to any recovery or indemnification sought by an Indemnified Party from a Responsible Party that does not involve a Third-Party Claim, if the Responsible Party does not notify the Indemnified Party within thirty (30) days from its receipt of the Claim Notice that such Responsible Party disputes such claim, which notice, if given, shall state with specificity the Responsible Party’s reasons for objecting (a “Dispute Notice”), the Responsible Party shall be deemed to have accepted and agreed with such claim.

9.7 OBJECTION TO CLAIMS

At the time of delivery of any Claim Notice to the Shareholders’ Agents, on behalf of a Responsible Party, a duplicate copy of such Claim Notice shall be concurrently delivered to the Escrow Agent to the extent the Indemnified Party is entitled to seek, and shall have elected to seek, recovery of its Damages from the Escrow Fund, and for a period of forty-five (45) days

- 88 -

after such delivery to the Escrow Agent, the Escrow Agent shall make no delivery of cash or other property pursuant to the Claim Notice unless the Escrow Agent shall have received written authorization from the Shareholders’ Agents to make such delivery. After the expiration of such forty-five (45) day period, the Escrow Agent shall make delivery of the cash or other property in the Escrow Fund in accordance with the Claim Notice, provided that no such payment or delivery may then be made if the Shareholders’ Agents shall have delivered a Dispute Notice to the Indemnified Party and duplicate copy of such Dispute Notice to the Escrow Agent, in each case prior to the expiration of such forty-five (45) day period.

9.8 RESOLUTION OF CONFLICTS; ARBITRATION

(a) In the event a Responsible Party delivers a Dispute Notice to the Indemnified Party with respect to any claim for indemnification under this Article 9 (including any Third-Party Claim), the Responsible Party and the Indemnified Party shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to each disputed claim. If the Indemnified Party is a Purchaser Indemnitee, and the Responsible Party and such Purchaser Indemnitee should so agree, then a memorandum setting forth such agreement shall be prepared and signed by both such parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the cash or other property to such Purchaser Indemnitee from the Escrow Fund in accordance with the terms thereof.

(b) If no agreement can be reached after good faith negotiation, either the Responsible Party or the Indemnified Party may, by written notice to the other, demand arbitration of the matter unless the Damages arises from a Third-Party Claim, in which event arbitration shall not be commenced until such amount is ascertained pursuant to Section 9.12 or the Responsible Party and the Indemnified Party agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Within fifteen (15) days after such written notice is sent, the Responsible Party shall select one arbitrator and the Indemnified Party shall select one arbitrator, and the two arbitrators so selected

- 89 -

shall select a third arbitrator. The decision of the arbitrators as to the validity and amount of any claim in the applicable Claim Notice shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 9.6, to the extent the Indemnified Party is a Purchaser Indemnitee and is entitled to seek, and shall have elected to seek, recovery of its Damages for any such claim from the Escrow Fund, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments to such Purchaser Indemnitee out of the Escrow Fund in accordance therewith.

(c) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in the Region of Ottawa-Carleton, Ontario, in accordance with theArbitration Act (Ontario). The costs of any arbitration Proceeding shall be allocated by the arbitrators.

9.9 SHAREHOLDERS’ AGENTS

9.12 THIRD-PARTY CLAIMS

In the event any Indemnified Party becomes aware of a third-party claim which such Indemnified Party intends to seek indemnity with respect thereto under this Article 9 (a “Third-Party Claim”), such Indemnified Party shall promptly notify the Responsible Party of such claim; provided, however, that the failure to so notify a Responsible Party shall not relieve such Responsible Party of its obligations hereunder, except to the extent that such Responsible Party is materially prejudiced thereby. The Indemnified Party shall have the right to settle any Third-Party Claim with the written consent of the Responsible Party, which consent shall not be unreasonably withheld or delayed; provided, however, that the Responsible Party may, subject to the other provisions of this Section 9.12, direct the settlement negotiations for or in defense of

such Third-Party Claim other than for or in defense of Third-Party Claims related to (i) the Company Intellectual Property Rights, (ii) disputes or disagreements with customers of the Offeror, Purchaser Parent Co. or the Company, (iii) disputes relating to Taxes where a greater portion of the Taxes in dispute would not be subject to indemnification by the Former Company Shareholders or (iv) Third-Party Claims by a Governmental Authority. In the event that the Responsible Party has consented to any such settlement, the Responsible Party Shareholders’ Agents shall not have any power or authority to objection under Section 9.7 or any other provision of this Agreement to the amount of any claims by the Indemnified Party for indemnity with respect to such settlement. If any Third-Party Claim is based on matters other than (i) the Company Intellectual Property Rights, (ii) disputes or disagreements with customers of the Offeror, Purchaser Parent Co. or the Company, (iii) disputes relating to Taxes where a greater portion of the Taxes in dispute would not be subject to indemnification by the Former Company Shareholders or (iv) Third-Party Claims by a Governmental Authority, then the Responsible Party may, at its option and upon written notice to the Indemnified Party within ninety (90) days of receiving notice from the Indemnified Party of such Third-Party Claim, contest or defend any such action, Proceeding, claim, demand or assessment, through counsel selected by the Responsible Party who is reasonably acceptable to the Indemnified Party; provided, however, that if the Indemnified Party shall reasonably object to such control, then the Responsible Party and the Indemnified Party shall cooperate in the defense of such matter; provided, further, that the Responsible Party shall not, except with the prior written consent of the Indemnified Party, enter into any settlement that (i) does not include as an unconditional term thereof the giving by the Person or Persons asserting such claim to the Indemnified Party of an unconditional release from all liability with respect to such claim or consent to entry of any judgment, (ii) does not involve only the payment of money damages, (iii) imposes an injunction or other equitable relief upon the Indemnified Party or (iv) includes any admission of wrongdoing or misconduct by the Indemnified Party.

- 94 -

pay or discharge the same without the prior written consent of the Shareholders’ Agents, which consent shall not be unreasonably withheld or delayed.

9.14 TAX TREATMENT OF INDEMNIFICATION PAYMENTS

The parties shall, to the extent permitted by Applicable Law, treat any indemnification payments paid or received pursuant to this Agreement for all Tax purposes as an adjustment to the purchase price paid for the Shares and the Stock Options, as the case may be. If the Indemnified Party will be liable for any additional Taxes as a result of the receipt of an indemnification payment, the Responsible Party will pay to the Indemnified Party in addition to the indemnification payment (i) an amount equal to such additional Taxes, plus (ii) any additional amounts required to pay additional Taxes imposed with respect to amounts received under clause (i) or this clause (ii), with the result that the Indemnified Party shall have received form the Responsible Party, net of the payment of all additional Taxes, an amount equal to the indemnification payment.
