Terms not otherwise defined herein are defined in Section 8.11. W I T N E S S E T H: WHEREAS, the Boards of Directors of BioChem, Shire and Exchangeco deem it advisable and in the best interests of each corporation and its respective shareholders that BioChem and Shire engage in a business combination in order to advance the long-term strategic business interests of BioChem and Shire; WHEREAS, the combination of BioChem and Shire shall be effected by the terms of this Agreement through a plan of arrangement, pursuant to Section 192 of the Canada Business Corporation Act (the "CBCA"), of Exchangeco, Shire and BioChem; WHEREAS the Arrangement is intended to (i) provide to holders of BioChem Common Shares who are residents of Canada for purposes of the ITA with the opportunity to dispose of their BioChem Common Shares in return for Exchangeable Shares on a tax-deferred or "rollover" basis for Canadian income tax purposes; and (ii) be treated as a "pooling of interests" for financial reporting purposes under United States generally accepted accounting principles; WHEREAS, in order to induce Shire to enter into this Agreement and to consummate the Arrangement, concurrently with the execution and delivery of this Agreement, BioChem is entering into a share option agreement with Shire pursuant to which BioChem has granted to Shire an option, exercisable under the circumstances specified therein, to purchase up to 19.9% of the outstanding BioChem Common Shares as of December 8, 2000 on an undiluted basis; NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby and thereby, the parties hereto agree as follows: ARTICLE I THE ARRANGEMENT 1.1 Closing.

The notice of motion for the application referred to in Section 1.3(a) shall request that the Interim Order provide: (a) for the class of Persons to whom notice is to be provided in respect of the Arrangement and the BioChem Shareholders Meeting and for the manner in which such notice is to be provided; (b) that the requisite approval for the Arrangement Resolution shall be 662/3% of the votes cast on the Arrangement Resolution by the shareholders of BioChem present in person or by proxy at the BioChem Shareholders Meeting or as may be decided by the Court; (c) for the grant of the Dissent Rights; and (d) that, in all other respects, the terms, restrictions and conditions of the bylaws and articles of amalgamation of BioChem, including quorum requirements and all other matters, shall apply in respect of the BioChem Shareholders Meeting. 1.6 Articles of Arrangement. (a) The Articles of Arrangement shall provide, among other things, that at the Effective Time, by virtue of the Arrangement and without any action on the part of the BioChem shareholders, each issued and outstanding BioChem Common Share (other than BioChem Common Shares held by dissenting shareholders and cash in lieu of fractional shares) shall be -4- converted (through the steps described in Exhibit A hereto) into Shire Ordinary Shares or Exchangeable Shares, at the election of each BioChem shareholder (provided that a holder who is not a Canadian resident for the purpose of the ITA shall not be entitled to receive Exchangeable Shares). The number of Shire Ordinary Shares or Exchangeable Shares into which each BioChem Common Share shall be converted (the "Exchange Ratio") shall be determined as follows: - --------------------------------------------------------- ------------------------------------------- If the Shire ADSs Price is: the Exchange Ratio shall be: - --------------------------------------------------------- ------------------------------------------- less than or equal to US $47.20 2.3517 - --------------------------------------------------------- ------------------------------------------- greater than US $47.20 and less than US $70.80 determined by dividing US $37.00 by the Shire ADSs Price and multiplied by 3 - --------------------------------------------------------- ------------------------------------------- equal to or greater than US $70.80 1.5678 - --------------------------------------------------------- ------------------------------------------- (b) Notwithstanding Section 1.6(a), if a BioChem shareholder elects, Shire will provide such BioChem shareholder with one-third of a Shire ADSs (represented by Shire ADSs) for each Shire Ordinary Share such shareholder would be entitled to receive pursuant to Section 1.6(a). Shire will pay all fees and expenses associated with the issuance of the Shire Ordinary Shares constituting Shire ADSs to Morgan Guaranty Trust Company of New York, as depositary (the "Depositary"), for the issuance by the Depositary of the associated Shire ADSs. 1.7 BioChem Shares Options. The Articles of Arrangement shall further provide that each BioChem Share Option that was granted pursuant to the BioChem Share Option Plan prior to the Effective Date, each Investissement Quebec Option and each BioChem Warrant which has not been exercised and remains outstanding immediately prior to the Effective Date shall upon the Effective Date be adjusted and become an option or a right, as applicable, to receive the number of Shire Ordinary Shares or Shire ADSs that the holder of such BioChem Share Option, Investissement Quebec Option or BioChem Warrant would have received if he or she had exercised such BioChem Share Option, Investissement Quebec Option or BioChem Warrant immediately prior to the Effective Date. The exercise price for each such Shire Ordinary Share or Shire ADS under such BioChem Share Option, Investissement Quebec Option or BioChem Warrant remaining outstanding after the Effective Date will be equal to (y) the aggregate exercise price immediately prior to the Effective Date of the BioChem Common Shares purchasable pursuant to such BioChem Share Option, Investissement Quebec Option or BioChem Warrant divided by (z) the whole number of Shire Ordinary Shares or Shire ADSs deemed purchasable pursuant to such BioChem Share Option, Investissement Quebec Option or BioChem Warrant in accordance with the foregoing, rounded up to the nearest whole cent. It is the intent of the parties that the exchange of options pursuant to this Section be covered by Subsection 7(1.4) of the ITA. -5- 1.8 BioChem Deferred Share Unit Plans and Restricted Share Unit Plan. Upon the Effective Date, Shire shall assume all of the obligations of BioChem under the BioChem Deferred Share Unit Plans and the BioChem Restricted Share Unit Plan in accordance with the terms and conditions of such plans. 1.9 Certain Adjustments. If, between the date of this Agreement and the Effective Date, the outstanding Shire Ordinary Shares or the BioChem Common Shares shall have been changed into a different number of shares or different class by reason of any reclassification, recapitalization, share split, split-up, combination or exchange of shares or any extraordinary dividend payable in cash or property or a stock dividend or dividend payable in any other securities shall be declared with a record date within such period, or any similar event shall have occurred, the number of Shire Ordinary Shares to be received by the holders of BioChem Common Shares shall be appropriately adjusted to provide to the holders of BioChem Common Shares the same economic effect as contemplated by this Agreement prior to such event. ARTICLE II EXCHANGE OF CERTIFICATES 2.1 Exchange Fund. Prior to the Effective Date, Shire shall appoint a commercial bank or trust company reasonably acceptable to BioChem having net capital of not less than $300,000,000, or a subsidiary thereof, to act as exchange agent hereunder for the purpose of exchanging Certificates for the Merger Consideration (the "Exchange Agent"). At or prior to the Effective Date, Shire shall and shall cause Exchangeco to deposit with the Exchange Agent, in trust for the benefit of holders of BioChem Common Shares, certificates representing the Shire Shares issuable on the Effective Date in exchange for BioChem Common Shares or effect the necessary CREST or other electronic transfers. Any cash in lieu of fractional Shire Shares (as set forth below) and certificates of Shire Shares deposited with the Exchange Agent shall hereinafter be referred to as the "Exchange Fund." 2.2 No Further Ownership Rights in BioChem Common Shares. All Shire Shares issued and cash paid upon conversion of BioChem Common Shares in accordance with the terms of the Plan of Arrangement shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to the BioChem Common Shares. 2.3 No Fractional Shire Shares. -6- (a) No certificates or scrip or Shire Shares representing fractional Shire Shares or book-entry credit of the same shall be issued upon the surrender for exchange of Certificates and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a shareholder of Shire or a holder of Shire Shares. (b) Notwithstanding any other provision of this Agreement, each holder of BioChem Common Shares exchanged pursuant to this Agreement who would otherwise have been entitled to receive a fraction of a Shire Share (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest), the whole as set forth in the Plan of Arrangement. 2.4 Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates for six months after the Effective Date shall be delivered to Shire or otherwise on the instruction of Shire, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Shire for any cash in lieu of fractional Shire Shares to which such holders are entitled pursuant to Section 2.3. Any such portion of the Exchange Fund remaining unclaimed by holders of Certificates five years after the Effective Date (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity) shall, to the extent permitted by law, become the property of Shire free and clear of any claims or interest of any Person previously entitled thereto. 2.5 No Liability. None of Shire, Exchangeco, BioChem or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. 2.6 Investment of the Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Shire on a daily basis; provided, that no such investment or loss thereon shall affect the amounts payable to BioChem shareholders pursuant to the Plan of Arrangement and the other provisions of this Article II. Any interest and other income resulting from such investments shall promptly be paid to Shire. 2.7 Lost Certificates. If any Certificate 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 and, if required by Shire, the posting by such Person of a bond in such reasonable amount as Shire may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate any cash in lieu of fractional Shire Shares pursuant to this Agreement. -7- 2.8 Withholding Rights. Shire shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of BioChem Common Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the ITA and the rules and regulations promulgated thereunder, or any provision of state, provincial, local or foreign tax law. To the extent that amounts are so withheld by Shire, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the BioChem Common Shares in respect of which such deduction and withholding was made by Shire provided that such withheld amounts are actually remitted to the appropriate taxing authority. 2.9 Affiliates. Notwithstanding anything to the contrary herein, to the fullest extent permitted by law, no certificates representing Shire Shares or cash shall be delivered to a Person who may be deemed an "affiliate" of BioChem in accordance with Section 5.11 hereof for purposes of Rule 145 under the Securities Act of 1933, as amended (the "Securities Act") until such Person has executed and delivered an Affiliate Agreement to Shire.

The copies of the certificate of incorporation and Memorandum and Articles of Association of Shire, which were previously furnished or made available -8- to BioChem, are true, complete and correct copies of such documents as in effect on the date of this Agreement. (ii) Section 3.1(a)(ii) of the Shire Disclosure Schedule sets forth all the Subsidiaries of Shire which, as of the date of this Agreement, are Significant Subsidiaries (as defined in Rule 1-02 of Regulation S-X of the SEC).

No Subsidiary of Shire is required to file any form, report, registration statement, prospectus or other document with the SEC. None of the Shire SEC Reports, as of their respective dates (and, if amended or superseded by a filing prior to the date of this Agreement or the Closing Date, then on the date of such filing), contained or will contain any untrue statement of a material fact or omitted or will 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 were made, not misleading.

Shire and its Subsidiaries are in compliance with the terms of the Shire Permits, except where the failure to so comply, in the aggregate, would not have a Material Adverse Effect on Shire. Except as disclosed in the Shire SEC Reports filed prior to the date of this Agreement, neither Shire nor any of its Subsidiaries is in violation of, and Shire and its Subsidiaries have not received any notices of violations with respect to, any laws, ordinances or regulations of any Governmental Entity, except for violations which, in the aggregate, would not have a Material Adverse Effect on Shire.

(ii) Except as disclosed in the Shire SEC Reports filed prior to the date of this Agreement, none of the Plans with respect to Shire is subject to the United States Employee Retirement Income Security Act of 1974, as amended ("ERISA"). With respect to each Plan that is subject to ERISA (an -17- "ERISA Plan") and any ERISA Affiliate Plan (A) if such ERISA Plan is intended to be qualified under Section 401(a) of the Code, such ERISA Plan has been determined by the United States Internal Revenue Service (the "IRS") to be so qualified and each trust related to any such ERISA Plan has been determined to be exempt from federal income Tax under Section 501(a) of the Code and no circumstance has occurred or exists which might reasonably be expected to cause such plan or trust to cease being so qualified or exempt from Tax; (B) such ERISA Plan has complied in all material respects with ERISA, and all other applicable Laws; (C) no accumulated funding deficiency, as defined in Section 302 of ERISA and Section 412 of the Code, whether or not waived, exists with respect to such Plan or any ERISA Affiliate Plan; (D) with respect to each single-employer ERISA Plan and ERISA Affiliate Plan subject to Title IV of ERISA, as of the last day of the most recent plan year ended prior to the date hereof, the actuarially determined present value of all "benefit liabilities" (as defined under Section 4001(a)(16) of ERISA) under such plan, determined on the basis of the actuarial assumptions in effect for such plan year, did not exceed the then current value of the assets of such plan; and (E) none of Shire, any of its Subsidiaries or any ERISA Affiliate has incurred or expects to incur any liability to the United States Pension Benefit Guaranty Corporation with respect to any ERISA Plan or ERISA Affiliate Plan or any withdrawal liability under Title IV of ERISA with respect to any "Multiemployer Plan", where the effect of such event, condition, action or failure to act under (A) through (E) above would, in the aggregate, have a Material Adverse Effect on Shire. Except as disclosed in the Shire SEC Reports filed prior to the date of this Agreement, none of Shire, or any of its Subsidiaries maintains or contributes to any employee welfare benefit plan (as defined in Section 3(1) of ERISA) which is subject to ERISA and which provides medical benefits to employees after termination of employment other than as required by Section 601 of ERISA or other applicable Law, or the cost of which is paid for by the covered employees. (iii) For purposes of this Agreement, "ERISA Affiliate" means (A) any corporation which is a member of the same controlled group of corporations, within the meaning of Section 414(b) of the Code, as Shire or BioChem, as the case may be, or any of their respective Subsidiaries, as the case may be, or (B) any partnership or trade or business (whether or not incorporated) under common control, within the meaning of Section 414(c) of the Code, with Shire or BioChem, as the case may be, or any of their respective Subsidiaries; "Multiemployer Plan" means any Plan that is a "multiemployer plan" (as defined in Section 4001(a)(3) of ERISA); and "ERISA Affiliate Plan" means any single-employer plan subject to Title IV or Section 302 of ERISA maintained or contributed to by an ERISA Affiliate. -18- (o) Licenses. Shire and its Subsidiaries have obtained all permits, concessions, grants, franchises, licenses and other federal, state, local or foreign governmental authorizations and approvals (collectively, "Licenses") material, individually or in the aggregate, to the conduct of the business of Shire and its Subsidiaries taken as a whole. All of such Licenses are in full force and effect and, to the knowledge of Shire, will not be impaired or adversely affected by the Arrangement in a manner or to a degree that would have a Material Adverse Effect on Shire. There is not pending or, to the knowledge of Shire, threatened any domestic or foreign suit or proceeding with respect to the suspension, revocation, cancellation, modification or non-renewal of any of such Licenses, and no event under the control of Shire has occurred that (whether with notice or lapse of time, or both) would result in a suspension or revocation of or failure to renew any of the Licenses, the loss of which would have a Material Adverse Effect on Shire. (p) Pooling of Interests. Neither Shire nor any of its Affiliates has taken or agreed to take any action or failed to take any action that would prevent the Arrangement from being treated for financial accounting purposes as a "pooling of interests" in accordance with US GAAP and the regulations and interpretations of the SEC. 3.2 Representations and Warranties of BioChem.

Except as Publicly Disclosed by BioChem prior to the date of this Agreement, none of BioChem, or any of its Subsidiaries maintains or contributes to any employee welfare benefit plan (as defined in Section 3(1) of ERISA) which is subject to ERISA and which provides medical benefits to employees after termination of employment other than as required by Section 601 of ERISA or other applicable Law, or the cost of which is paid for by the covered employees. (p) Licenses. BioChem and its Subsidiaries have obtained all Licenses material, individually or in the aggregate, to the conduct of the business of BioChem and its Subsidiaries taken as a whole. All of such Licenses are in full force and effect and, to the knowledge of BioChem, will not be impaired or adversely affected by the Arrangement in a manner or to a degree that would have a Material Adverse Effect on BioChem. There is not pending or, to the knowledge of BioChem, threatened any domestic or foreign suit or proceeding with respect to the suspension, revocation, cancellation, modification or non-renewal of any of such licenses, and no event under the control of BioChem has occurred that (whether with notice or lapse of time, or both) would result in a suspension or revocation of or failure to renew any of the Licenses, the loss of which would have a Material Adverse Effect on BioChem.

If at any time prior to the Effective Date any information relating to Shire or BioChem, or any of their respective affiliates, officers or directors, should be discovered by Shire or BioChem which should be, or should have been, set forth in the Listing Particulars and/or the Class 1 Circular so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or Shire or BioChem should become aware of a significant change affecting any matter contained in the Listing Particulars or the Class 1 Circular whose inclusion was required by Section 146 of the Financial Services Act 1986 or by the Listing Rules, or of a significant new matter the inclusion of information in respect of which would have been so required if it had arisen when the Listing Particulars or the Class 1 Circular were prepared, the party which discovers such information or, as the case may be, becomes aware of any such significant change or significant new matter, shall promptly notify the other party hereto and, to the extent required by law, rules or regulations, supplementary listing particulars shall promptly be issued and disseminated to the shareholders of Shire and the shareholders of BioChem.

Notwithstanding anything in this Agreement, the Board of Directors of Shire may make a Change in the Shire Recommendation in the circumstances contemplated in Section Shire Acquisition Proposals hereof and in any other circumstances provided the Board of Directors of Shire concludes in good faith (after receiving a written opinion from outside counsel independent from Shire, a copy of which shall be provided to BioChem) taking into account, among other things, all legal, financial, regulatory and other aspects of the circumstances as well as the binding nature of the commitments, undertakings and covenants of Shire under this Agreement, that the Board of Directors of Shire is required under such Laws to make a Change in the Shire Recommendation in order to discharge its fiduciary duties. The parties understand and agree that a variation of the market price of the Shire ADSs or the Shire Ordinary Shares absent any material change in BioChem shall not constitute a circumstance whereby the Board of Directors of Shire may effect a Change in the Shire Recommendation. (g) For purposes of this Agreement, a Change in the BioChem Recommendation shall be deemed to include, without limitation, a recommendation by the BioChem Board of Directors of a third party Acquisition Proposal with respect to BioChem.
