President and Chief Executive Officer

Dear Sirs:

          Orion Securities Inc. (“Orion”), Sprott Securities Inc., First Associates Investments Inc., Raymond James Inc. and Research Capital Corporation (collectively the “Underwriters”) hereby offer to purchase from Cardiome Pharma Corp. (the “Company”) 3,810,000 common shares in the capital of the Company (the “Purchased Shares”) at a price of $5.25 per Purchased Share (the “Offering Price”) for gross proceeds to the Company of $20,002,500. The Company understands, with respect to offers and sales of the Offered Shares in the United States, that although the offer to purchase the Offered Shares is presented on behalf of the Underwriters as purchasers, the Underwriters will endeavour to arrange for substituted purchasers to purchase the Offered Shares directly from the Company.

          In addition, the Company hereby grants to the Underwriters, for the purpose of market stabilization and satisfying any over-allotments, a non-assignable option (the “Over-Allotment Option”), to purchase and offer for sale to the public pursuant to the Prospectus (as hereinafter defined) for up to 30 days following the Closing Date (as hereinafter defined), up to an additional 571,500 common shares in the capital of the Company (the “Over-Allotment Option Shares”), which Over-Allotment Option shall be exercisable in whole or in part by any one of the Underwriters at the Offering Price, by the Underwriter or Underwriters, as the case may be, giving two business days (as hereinafter defined) written notice to the Company prior to the exercise thereof. In the event that the Over-Allotment Option is exercised, one or more separate closings (individually, an “Over-Allotment Closing”) shall be held, and all the terms and conditions relating to the closing herein (including the payment of the Underwriters’ Fee (as hereinafter defined)) shall apply to each Over-Allotment Closing, except as otherwise agreed upon by the Company and the Underwriters. The Purchased Shares, together with the Over-Allotment Option Shares, are referred to herein as the “Offered Shares” The offering of the Offered Shares is referred to herein as the “Offering”.

          In the event that the Company shall subdivide, consolidate, reclassify or otherwise exchange the common shares in the capital of the Company (the “Shares”) during the period in which the Over-Allotment Option is exercisable, the Company hereby agrees to make corresponding adjustments to the exercise price of the Over-Allotment Option and to the number of Over-Allotment Option Shares issuable upon the exercise thereof such that the Underwriters

- 2 -

shall be entitled to receive the same number and type of securities that they would have otherwise received had they exercised the Over-Allotment Option prior to such occurrence. Notice shall be given to the Underwriters of such adjustment. In the event that the Underwriters shall disagree with the foregoing adjustment, such adjustment shall be determined conclusively by the Company’s auditors, absent manifest error, at the Company’s expense.

          This offer is conditional, among other things, upon the Company filing and obtaining receipts for a preliminary short form prospectus (the “Preliminary Prospectus”) and a (final) short form prospectus (the “Final Prospectus”) in respect of the Offered Shares with the securities regulatory authorities in each of the provinces of Canada (collectively, the “Qualifying Provinces”) under the applicable securities legislation of each of the Qualifying Provinces (the “Applicable Laws”), pursuant National Instrument 44-101 entitled “Short Form Prospectus Distributions” qualifying the distribution by the Company of the Offered Shares to purchasers resident in the Qualifying Provinces. The Company will elect to have the Preliminary Prospectus and the Final Prospectus (collectively, the “Prospectus”) reviewed under the expedited review system utilizing the Mutual Reliance Review System contemplated by National Policy 43-201 of the Canadian Securities Administrators. In the event that the Underwriters offer the Offered Shares in jurisdictions other than the Qualifying Provinces, the Underwriters will not solicit offers to purchase or sell the Offered Shares so as to require registration thereof or filing of a prospectus, registration statement or similar disclosure document with respect thereto under the laws of any jurisdiction other than the Qualifying Provinces and will require each Selling Firm (as hereinafter defined) to agree with the Underwriters not to so solicit or sell, which agreements will be held in trust by the Underwriters for the benefit of the Underwriters and the Company. For the purposes of this agreement, “Preliminary Prospectus”, “Final Prospectus” and “Prospectus” refer to the subject document, together with all other documents incorporated or deemed to be incorporated therein by reference.

          This offer is also conditional upon (i) the Company filing the Preliminary Prospectus in the Qualifying Provinces no later than September 8, 2003 and obtaining by such date a preliminary expedited (or mutual reliance) review receipt document (the “Preliminary Receipt”) from the British Columbia Securities Commission, evidencing that a receipt for the Preliminary Prospectus has been issued by the securities regulatory authority in each of the Qualifying Provinces (collectively, the “Securities Commissions”) and the Company shall use its best efforts to obtain the Preliminary Receipt on or before such date; and (ii) the Company filing the Final Prospectus in the Qualifying Provinces no later than September 15, 2003 (or such later date as may be agreed to in writing by the Company and the Underwriters) and obtaining by such date an expedited (or mutual reliance) review receipt document from the British Columbia Securities Commission evidencing that a receipt for the Final Prospectus has been issued by each of the Securities Commissions, or otherwise obtained a receipt for the Final Prospectus from each of the Securities Commissions (in either case, the “Final Receipt”) and the Company shall use its best efforts to obtain the Final Receipt on or before such date.

          The Company shall pay to the Underwriters a fee (the “Underwriters’ Fee”) at the Closing Time (as hereinafter defined) equal to 5.5% of the aggregate gross proceeds of the Offering in consideration of the services to be rendered by the Underwriters in connection with the Offering. Such services shall include, without limitation: (i) acting as financial advisors to the Company in the preparation of documentation relating to the sale of the Offered Shares; (ii)

F.         RIGHTS OF TERMINATION

          All terms and conditions of this agreement shall be construed as conditions and any breach or failure to comply by the Company with any such terms and conditions in favour of the Underwriters shall entitle the Underwriters to terminate their obligations to purchase the Offered Shares by written notice to that effect given to the Company prior to the Closing Time.

          In addition to any other remedies which may be available to the Underwriters, the Underwriters or any Underwriter shall be entitled, at its option to terminate and cancel, without any liability on such Underwriter’s part, its obligations under this agreement to purchase or offer for sale the Offered Shares by giving written notice to the Company at any time through to the Closing Time if:

(i)

there shall be any material change in the affairs of the Company, or there should be discovered any previously undisclosed material fact required to be disclosed in the Final Prospectus or there should occur a change in a material fact contained in the Final Prospectus, in each case which, in the opinion of the Underwriters, acting reasonably, has or would be expected to have a materially adverse effect on the market price or value of the Common Shares or;

if there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence, any acts of terrorism or hostilities or escalation thereof or other calamity or crises, or any law or regulation which in the opinion of the Underwriters, acting reasonably, materially adversely affects, or would be expected to materially adversely affect, the financial markets in Canada or the United States or the business, operations or affairs of the Company and the Subsidiaries taken as a whole.

          The applicable Underwriter shall make reasonable efforts to give notice to the Company (in writing or by other means) of the occurrence of any of the events referred to in clauses (i), (ii) or (iii) of this termination right, provided that neither the giving nor the failure to give such notice shall in any way affect the entitlement of such Underwriters to exercise this right at any time through to the Closing Time.

          The rights of termination contained in this Part F may be exercised by the Underwriters and are in addition to any other rights or remedies the Underwriters may have in respect of any default, act or failure to act or non-compliance by the Company in respect of any of the matters contemplated by this agreement.

G.       INDEMNITY

          The Company covenants and agrees to indemnify the Underwriters and their respective shareholders, directors, officers, employees and agents (each being hereinafter referred to as an “Indemnified Party”) against, and to reimburse the Underwriters promptly upon demand for any legal or other expenses reasonably incurred by the Underwriters in connection with investigating or defending, all losses (other than a loss of profits), claims, damages, liabilities, costs or expenses caused or incurred by reason of:

(a)	any statement, other than a statement relating solely to the Underwriters, contained in the Offering Documents which constitutes or is alleged to constitute a misrepresentation;
(b)	any statement, other than a statement relating solely to the Underwriters, contained in the Company’s Information Record which at the time and in the light of the circumstances under which it was made, contained or is alleged to have contained a misrepresentation;

- 19 -

(c)	the omission or alleged omission to state in any of the Offering Documents, in the Company’s Information Record or any certificate of the Company delivered hereunder or pursuant hereto any material fact required to be stated therein or necessary to make any statement therein not misleading in light of the circumstances under which it was made (other than omissions relating solely to the Underwriters);
(d)	any order made or inquiry, investigation or proceeding commenced or threatened by any securities regulatory authority or other competent authority based upon any misrepresentation or alleged misrepresentation in any of the Offering Documents, or the Company’s Information Record (other than a statement relating solely to the Underwriters and included in reliance upon and in conformity with information furnished to the Company in writing by the Underwriters specifically for use therein) which prevents or restricts the trading in the Shares or the distribution or distribution to the public, as the case may be, of any of the Offered Shares;
(e)	the Company not complying with any requirement of any Applicable Laws, regulatory requirements (including any private placement filing or other requirements under United States federal and state securities laws) or rules of any stock exchange or quotation system except as such non-compliance shall be as a result of the activities of the Underwriters; or
(f)	any breach of any representation or warranty of the Company contained herein or the failure of the Company to comply with any of its covenants or other obligations hereunder,

and will reimburse each Indemnified Party promptly upon demand for any legal expenses reasonably incurred in connection with investigating or defending any such losses, claims, damages, liabilities or actions in respect thereof, as incurred.

     If any action or claim shall be asserted against an Indemnified Party in respect of which indemnity may be sought from the Company pursuant to the provisions of this Part G or if any potential claim contemplated hereby shall come to the knowledge of an Indemnified Party, the Indemnified Party shall promptly notify the Company in writing; but the omission to so notify the Company shall not relieve the Company from any liability it may otherwise have to the Indemnified Party pursuant to this Part G. The Company shall be entitled but not obligated to participate in or assume the defence thereof; provided, however, that the defense shall be through legal counsel acceptable to the Indemnified Party, acting reasonably. In addition, the Indemnified Party shall also have the right to employ separate counsel in any such action and participate in the defense thereof, and the fees and expenses of such counsel shall be borne by the Indemnified Party unless:

(a) the employment thereof has been specifically authorized in writing by the Company;

- 20 -

(a)	the Indemnified Party has been advised by counsel that representation of the Company and the Indemnified Party by the same counsel would be inappropriate due to actual or potential differing interests between them; or
(b)	the Company has failed within a reasonable time after receipt of such written notice to assume the defense of such action or claim;

provided that in no event shall the Company be required to assume the fees and expenses of more than one counsel for all Indemnified Parties. Neither party shall effect any settlement of any such action or claim or make any admission of liability without the written consent of the other party, such consent to be promptly considered and not to be unreasonably withheld. The indemnity hereby provided for shall remain in full force and effect and shall not be limited to or affected by any other indemnity in respect of any matters specified herein obtained by the Indemnified Party from any other person.

          To the extent that any Indemnified Party is not a party to this agreement, the Underwriters shall obtain and hold the right and benefit of the indemnity provisions of this Part G in trust for and on behalf of such Indemnified Party.

H.       CONTRIBUTION

          In the event that the indemnity provided for above is, for any reason, illegal or unenforceable as being contrary to public policy or for any other reason, the Underwriters and the Company shall contribute to the aggregate of all losses, claims, costs, damages, expenses or liabilities (including any legal or other expenses reasonably incurred by the Indemnified Party in connection with investigating or defending any action or claim which is the subject of this section but excluding loss of profits or consequential damages) of the nature provided for above such that the Underwriters shall be responsible for that portion represented by the percentage that the Underwriters’ Fee payable by the Company to the Underwriters bears to the gross proceeds from the sale of the Offered Shares and the Company shall be responsible for the balance, provided that, in no event, shall any Underwriters be responsible for any amount in excess of the amount of the Underwriters’ Fee actually received by it. In the event that the Company may be held to be entitled to contribution from the Underwriters under the provisions of any statute or law, the Company shall, in respect of the Underwriters, be limited to contribution in an amount not exceeding the lesser of: (i) the portion of the full amount of losses, claims, costs, damages, expenses and liabilities, giving rise to such contribution for which the Underwriters are responsible, as determined above, and (ii) the amount of the Underwriters’ Fee actually received by the Underwriters. Notwithstanding the foregoing, a party guilty of fraudulent misrepresentation shall not be entitled to contribution from the other party. Any party entitled to contribution will, promptly after receiving notice of commencement of any claim, action, suit or proceeding against such party in respect of which a claim for contribution may be made against the other party under this section, notify such party from whom contribution may be sought. In no case shall such party from whom contribution may be sought be liable under this agreement unless such notice has been provided, but the omission to so notify such party shall not relieve the party from whom contribution may be sought from any other obligation it may have otherwise than under this section. The right to contribution provided in this section shall be in

- 21 -

addition and not in derogation of any other right to contribution which the Underwriters or the Company may have by statute or otherwise by law.

I.        ACTION BY UNDERWRITERS

          All steps which must or may be taken by the Underwriters in connection with this agreement, with the exception of the matters relating to termination contemplated by Part F or matters relating to indemnity and contribution contemplated by Parts G and H, may be taken by Orion Securities Inc. on behalf of itself and the other Underwriters and the execution and delivery of this agreement by the Company and the Underwriters shall constitute the Company’s authority for accepting notification of any such steps from, and for delivery of the definitive documents constituting the Offered Shares to, Orion Securities Inc.

Raymond James Ltd.	5.55%
Research Capital Corporation	5.55%

          If any of the Underwriters shall fail to purchase its applicable percentage of the total number of such of the Offered Shares at the Closing Time pursuant to the Offering and such failure shall constitute a default in its obligations under this agreement, then the other Underwriters shall be relieved of their obligations hereunder provided that, notwithstanding the provisions of this paragraph, any Underwriter not in default of its obligations under this agreement may, but shall not be obligated to, purchase such of the Offered Shares which the Underwriter in default was to have purchased. Nothing in this paragraph shall oblige the Company to sell to any or all of the Underwriters less than all of the aggregate amount of the Purchased Shares (and any Over-Allotment Option Shares which the Underwriters have agreed to purchase pursuant to the exercise of the Over-Allotment Option) or shall relieve any of the Underwriters in default hereunder from liability to the Company.
