Section 2.2     Purchase Price and Payment Procedures

     Section 2.3(2) is hereby amended by inserting the following new sub-section immediately after Section 2.3(2):

“2.3(2)(a). A portion of each twenty-five million dollar ($25,000,000) Cash Flow Payment payable pursuant to Schedule 2.3.2, at the Closing of the Design Operations conducted by the Canada Design Employees at the Ottawa Lab 2/Lab 10 Facility and by the UK Design Employees at the Monkstown Facility, is intended to represent an advance of the portions of the two hundred million dollars ($200,000,000) referenced in Section 2.3(1) that represent part of the Purchase Price with respect to the other Facilities. Notwithstanding the foregoing:

(i)     in the event that the Closing for the Montreal BAN 1 Facility, the Montreal BAN 3 Facility and the Montreal OPTO 1 Facility (collectively, the “Montreal Facilities”) shall not have occurred on or before February 1, 2005, then (a) Purchaser shall not be required to pay the instalment of twelve million five hundred thousand dollars ($12,500,000) otherwise payable on such date pursuant to Section 2.3(3) until the earlier of (I) the Closing for the Montreal Facilities, and (II) September 1, 2005, and (b) Seller shall not be required to pay any Transition Payment instalments otherwise payable on such date pursuant to Section 5.18, until the earlier of (I) the Closing for the Montreal Facilities, and (II) September 1, 2005 (which September 1, 2005, payments shall each be subject to Section 2.3(2)(c));

(ii)     in the event that (a) the Closing for the Montreal Facilities shall not have occurred on or before May 1, 2005, and (b) the Closing for the Calgary Westwinds Facility shall not have occurred on or before May 1, 2005, then (I) Purchaser shall not be required to pay the instalment of twelve million five hundred thousand dollars ($12,500,000) otherwise payable on such date pursuant to Section 2.3(3) until the earlier of (A) the Closings for the Calgary Westwinds Facility, and (B) September 1, 2005, and (II) Seller shall not be required to pay any Transition Payment instalments otherwise payable on such date pursuant to Section 5.18, until the earlier of (A) the Closing for the Calgary Westwinds Facility, and (B) September 1, 2005 (which September 1, 2005, payments shall each be subject to Section 2.3(2)(c)); and

(iii)     in the event that the Closing for the Monkstown Facility or the Calgary Westwinds Facility shall not have occurred on or before September 1, 2005, then the amount payable by the Purchaser to the Seller on that date shall be reduced by the portion thereof, if any, that represented an advance of a portion of the Purchase Price for such Facility/Facilities. The Parties further agree that the amount payable by the Seller to the Purchaser on that date as a Transition Payment shall be reduced by the same percentage as the reduction in the amount payable by the Purchaser to the Seller referred to above in this paragraph.

2.3(2)(b).     If the Closing for the Montreal Facilities does not occur on or before March 1, 2005, the Parties shall within ten (10) days of such date meet to negotiate in good faith the portion of Design Operations Cash Flow Payment that represented the amount of the fifty million dollars ($50,000,000) allocable to the first Closing (Design Operations). If the Parties are not able to reach agreement on such amount within twenty five (25) days of March 1, 2005 (“Drop Dead Date”), then, notwithstanding anything to the contrary in this Agreement, the Parties shall negotiate the Settlement Transaction (as defined below).

2.3(2)(c).     (i)     If the Drop Dead Date shall have passed without agreement as set forth in Section 2.3 (2)(b), the Parties shall within two (2) Business Days of such date commence the repurchase by the Seller of the Design Operations transferred in the first Closing and to terminate the Agreement with respect to the other Facilities, with such termination to be effective as of the closing date of the Settlement Transaction but otherwise in accordance with the terms of the Agreement.

(ii)     From the commencement of the negotiations, Purchaser shall maintain the Assets and operate the Design Operations in the ordinary course for the benefit of Seller.

(iii)    The Parties agree to negotiate terms of the repurchase (“Settlement Transaction”) such that they shall ensure the economic effect as of sixty (60) days after the commencement of the Settlement Transaction negotiations, and that the Settlement Transaction shall include the following terms:

(a)     At the Settlement Transaction, (I) Seller shall pay to Purchaser the sum of seven million eight hundred and three thousand one hundred and forty six dollars ($7,803,146), less applicable depreciation on the Assets transferred for the period November 1, 2004 to May 1, 2005 (the “Settlement Purchase Price”), and shall waive its right, if any, to receive any deferred portions of such Cash Flow Payments, and (II) Purchaser shall waive its right, if any, to receive any deferred portions of any Transition Payments that have not already been paid (but shall be entitled to retain those Transition Payments that were paid on November 1, 2004), and neither Party shall be entitled to compensation for any Losses that it has or may have incurred prior to such negotiations commencing. By way of illustration, Purchaser shall not be entitled to recoup any Losses it may have incurred associated with running such Design Operations and Seller shall not be entitled to be reimbursed for failure of the Design Operations to provide services in accordance with the terms of the Amended and Restated Master Contract Manufacturing Services Agreement and the exhibits thereto, in each case during the time period prior to commencement of the Settlement Transaction negotiations; provided, however, that the foregoing shall not act as a waiver of Purchaser’s rights to be paid any amounts which are due for services previously provided to the Seller under the Amended and Restated Master Contract Manufacturing Services Agreement and the exhibits thereto but for which

either invoices have yet not been issued or such invoices have been issued but payment has not yet been made.

(b)     the Purchaser shall make the same representation and warranties to Seller as Seller made to Purchaser in the Agreement to the extent applicable under the circumstances.

(c)     all Transfer Taxes payable from the Settlement Transaction shall be paid by the Parties in accordance with the principles set forth for payment by the purchaser and seller, as the case may be, in Section 5.6 of the Agreement, mutatis mutandis.

(d)     the first Closing (Design Operations) Assets shall be transferred to Seller, at Purchaser’s cost, in the same condition as originally transferred by Seller, reasonable wear and tear excepted; provided, however, that if Purchaser is unable to return any Assets to Seller, or such Assets are physically damaged, reasonable wear and tear excepted (the “Non Transferred Assets”), the Settlement Purchase Price, less applicable depreciation on the Assets transferred for the period November 1, 2004 to May 1, 2005.

(e)     The Amended and Restated Master Contract Manufacturing Services Agreement and the other Transaction Documents (other than the Confidentiality Agreement) shall be terminated, effective as of the closing date of the Settlement Transaction, in accordance with their respective terms.

(f)     Purchaser shall promptly inform and consult with the employees’ representative of the UK Design Employees, and Seller shall cooperate with Purchaser in such process. With respect to any assets or employees in the UK, the Settlement Transaction shall constitute only an irrevocable binding offer by Seller to effect the transaction contemplated, which offer shall be deemed accepted, automatically and without further action on the part of any Person, upon due completion of such consultation process. With respect to the employees in Canada, Seller shall make offers of employment with terms and conditions which are substantially similar in the aggregate to the employees then-current terms and conditions; any transfer or offer of employment will, to the extent applicable, follow substantially the same processes as were followed in the transfer of employment from Seller to Purchaser.

(g)     Subject to any limitations under applicable Law, Seller shall be permitted to solicit any of the UK Design Employees or Canada Design Employees who became Transferring Employees and remain employed by Purchaser or one of its Affiliates at the time of the Settlement Transaction. Subject to any limitations under applicable Law, Purchaser and its Affiliates shall provide reasonable assistance to Seller with such solicitation efforts.

(h)     the Parties shall cooperate fully with one another to facilitate a smooth transition of the Design Operations, in order to allow Seller to fully assume and continue such Design Operations without material interruption in the services provided by the Purchaser pursuant to the Amended and Restated Manufacturing Services Agreement.

(i)     Purchaser and Seller shall take such additional actions and perform such additional tasks as may be reasonably necessary to ensure a timely transfer of the Design Operations to Seller.”
