                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (the "AGREEMENT") is made and entered
into as of October 26, 2001, by and between CORIXA CORPORATION, a Delaware
corporation ("CORIXA"), and AMERSHAM HEALTH, INC., a Delaware corporation
("PURCHASER").

                                    RECITALS

         A. Corixa and Amersham PLC (an affiliate of Purchaser) are parties to
that certain Development, Commercialization and License Agreement of even date
herewith (the "LICENSE AGREEMENT").

         B. Corixa and Amersham PLC are parties to that certain Manufacturing
and Supply Agreement of even date herewith (the "MANUFACTURING AGREEMENT").

         C. Pursuant to Section 8.1 of the License Agreement, Purchaser has
agreed to purchase an aggregate of $15,000,000 of common stock, $0.001 par value
per share, of Corixa (the "COMMON STOCK") in accordance with the terms and
conditions of this Agreement.

         NOW, THEREFORE, the Parties hereto agree as follows:

         1.       PURCHASE AND SALE.

         Subject to the terms and conditions hereof, and in reliance upon the
representations, warranties and agreements contained herein, Corixa hereby
agrees to issue and sell to Purchaser, and Purchaser hereby agrees to purchase
from Corixa, the aggregate number of shares of Common Stock determined in
accordance with Section 1.1 hereof.

                  1.1 SALE OF SHARES. On the First Closing Date (as defined in
Section 1.3), Corixa shall issue and sell to Purchaser, and Purchaser shall
purchase from Corixa that number of shares of Common Stock (the "First Closing
Shares") equal to the quotient of $5,000,000 divided by the First Closing
Purchase Price (as hereinafter defined). At the sole option of Corixa and
subject to Section 1.2, on the Second Closing Date (as defined in Section 1.3),
Corixa shall issue and sell to Purchaser, and Purchaser shall purchase from
Corixa that number of shares of Common Stock (the "Second Closing Shares") equal
to the quotient of $5,000,000 divided by the Second Closing Purchase Price (as
hereinafter defined). At the sole option of Corixa and subject to Section 1.2,
on the Third Closing Date (as defined in Section 1.3), Corixa shall issue and
sell to Purchaser, and Purchaser shall purchase from Corixa that number of
shares of Common Stock (the "Third Closing Shares") equal to the quotient of
$5,000,000 divided by the Third Closing Purchase Price (as hereinafter defined).
In the event the number of First Closing Shares, Second Closing Shares or Third
Closing Shares includes a fraction of a share, the number of First Closing
Shares, Second Closing Shares or Third Closing Shares (as applicable) shall be
increased to the nearest whole number of shares and the aggregate First Closing
Purchase Price, Second Closing Purchase Price or Third Closing Purchase Price
(as applicable) shall be increased to equal the First Closing Purchase Price,
Second Closing Purchase Price or Third Closing Purchase Price (as applicable)
times such whole number of shares. The "First Closing Purchase Price" shall
equal one hundred forty percent (140%) of the average of the closing prices of
the Common Stock on the Nasdaq National Market, as reported by the Wall Street
<PAGE>
Journal, Western Edition (the "Wall Street Journal"), for the ten (10) trading
days prior to the date of this Agreement and the ten (10) trading days following
and including the date of this Agreement. The "Second Closing Purchase Price"
and "Third Closing Purchase Price" (as applicable) shall equal the average of
the closing prices of the Common Stock on the Nasdaq National Market, as
reported by the Wall Street Journal for the ten (10) trading days prior to the
Notice Date (as defined in Section 1.2) and the ten (10) trading days following
and including the Notice Date.

                  1.2 OPTIONS OF CORIXA.

                           (a) Purchaser hereby grants Corixa the irrevocable
options to cause Purchaser to purchase (i) the Second Closing Shares at a price
per share equal to the Second Closing Purchase Price and (ii) the Third Closing
Shares at a price per share equal to the Third Closing Purchase Price (together,
the "Options"). Corixa may exercise the Options at any time during a period of
18 months following the date of this Agreement; provided however, that Corixa
shall not exercise the Options within 30 days of each other nor shall Corixa
exercise more than one (1) Option in the year 2001. In the event of termination
of the License Agreement and the Manufacturing Agreement, the Options will
remain in full effect and be legally binding obligations of Purchaser.

                           (b) To exercise the Options with respect to the
Second Closing Shares or the Third Closing Shares, Corixa shall notify Purchaser
in writing (an "Exercise Notice") specifying the exercise of such Option. The
date of delivery of such Exercise Notice to Purchaser is referred to as the
applicable "Notice Date," and the Option shall be deemed to have been validly
exercised on such Notice Date with respect to the Second Closing Shares or the
Third Closing Shares.

                  1.3 CLOSING DATES. The closing of the sale and purchase of the
First Closing Shares (the "First Closing") shall take place on the fifteenth
(15th) business day after the date of this Agreement or such later date as
Corixa and Purchaser may mutually agree or as may be specified in accordance
with the last sentence of this section (the "First Closing Date"). The closing
of the sale and purchase of the Second Closing Shares and the Third Closing
Shares (the "Second Closing" and "Third Closing," respectively) shall take place
on the fifteenth (15th) business day after the applicable Notice Date or such
later date as Corixa and Purchaser may mutually agree or as may be specified in
accordance with the last sentence of this section (the "Second Closing Date" and
"Third Closing Date," respectively). As used hereinafter, the terms "Closing"
and "Closing Date" shall refer to the First, Second or Third Closing and the
First, Second or Third Closing Date, as the context requires; the term "Shares"
shall refer to the First, Second and Third Closing Shares collectively or the
First, Second or Third Closing Shares, if and as the context requires; and the
term "Purchase Price" shall refer to the First, Second and Third Closing
Purchase Price collectively or the First, Second or Third Closing Purchase
Price, if and as the context requires. If for any reason Corixa is unable to
satisfy the closing conditions set forth in Section 4 of this Agreement as of
the scheduled Closing Date, then Corixa shall use its best efforts to satisfy
such conditions at the earliest practicable date, and the Closing Date shall be
rescheduled to such date as Corixa may specify (with at least five (5) business
days prior notice to Purchaser) on which Corixa can satisfy such closing
conditions.

                                      -2-
<PAGE>
                  1.4 DELIVERY. At the Closing, Corixa will execute and deliver
to Purchaser a certificate registered in the name of Purchaser, representing the
Shares to be purchased by Purchaser from Corixa, dated the Closing Date, against
payment of the aggregate Purchase Price for the Shares, by wire transfer, a
check made payable to the order of Corixa, or any combination thereof.

                  1.5 RULE 144 REPORTING. With a view to making available to
Purchaser the benefits of certain rules and regulations of the Securities and
Exchange Commission (the "SEC") which may permit the sale of the Shares to the
public without registration, Corixa agrees to use its best efforts to:

                           (a) Make and keep public information available, as
those terms are understood and defined in Rule 144 ("Rule 144") under the
Securities Act of 1933, as amended (the 1933 Act") or any similar or analogous
rule promulgated under the 1933 Act, as long as the Shares are outstanding;

                           (b) File with the SEC, in a timely manner, all
reports and other documents required of Corixa under the 1933 Act and the
Securities Exchange Act of 1934, as amended (the "1934 Act");

                           (c) Take all such action (including without
limitation the furnishing of the information described in Rule 144(d)(4)) as may
be necessary to facilitate a sale of the shares by Purchaser to a "qualified
institutional buyer," as such term is defined in Rule 144A of the 1933 Act.

                  1.6 "MARKET STAND-OFF" AGREEMENTS. Purchaser hereby agrees
that prior to the second anniversary of the First Closing Date, Second Closing
Date or Third Closing Date, as applicable, it shall not sell or otherwise
transfer or dispose of any of the First Closing Shares, Second Closing Shares or
Third Closing Shares, as applicable held by it. Corixa may impose stop-transfer
instructions with respect to securities subject to the foregoing restriction
until the expiration thereof. Following the second anniversary of the First
Closing Date, until termination of the License Agreement and Manufacturing
Agreement, if Purchaser desires to sell or otherwise transfer any Shares, then
Purchaser shall first give 5 days' written notice thereof to Corixa, describing
generally the basis upon which Purchaser proposes to sell or otherwise transfer
or dispose of such Shares.

                  1.7 STANDSTILL COVENANT. Other than the purchase of the Shares
contemplated by Section 1 of this Agreement, Purchaser agrees that, during the
term of the License Agreement and Manufacturing Agreement and for one year
thereafter, neither Purchaser nor any of its affiliates will in any manner,
directly or indirectly, without the written consent of the Company effect,
propose to effect or actively and consciously participate as a partner in (a)
any acquisition of any securities or assets of Corixa or (b) any tender or
exchange offer, merger, business combination, recapitalization or other
extraordinary transaction involving Corixa unless an unaffiliated third party
has already made an offer for all of the outstanding shares of Corixa and
neither Purchaser nor any of its affiliates possess any prior knowledge of, or
is involved in any manner with such an offer.

                                      -3-
<PAGE>
                  1.8 COOPERATION TO SATISFY CLOSING CONDITIONS. If any actions
are required to satisfy the closing conditions set forth herein, the Parties
shall take such actions as are reasonably required to satisfy such conditions on
a prompt basis.

         2.       REPRESENTATIONS AND WARRANTIES OF CORIXA.

         Corixa hereby represents and warrants to Purchaser that the following
matters shall be true as of the Closing:

                  2.1 ORGANIZATION AND STANDING; CERTIFICATE AND BYLAWS. Corixa
is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware, and has full power and authority to own and
operate its properties and assets and to carry on its business as presently
conducted and as proposed to be conducted. Corixa is qualified as a foreign
corporation to do business in each jurisdiction in the United States in which
the ownership of its property or the conduct of its business requires such
qualification, except where any statutory fines or penalties or any corporate
disability imposed for the failure to qualify would not materially adversely
affect Corixa, its assets, financial condition or operations.

                  2.2 AUTHORIZATION. All corporate action on the part of Corixa,
its officers, directors and stockholders necessary for the authorization,
execution and delivery of this Agreement, the performance of all Corixa's
obligations hereunder, and for the authorization, issuance, sale and delivery of
the Shares has been taken or will be taken prior to Closing. This Agreement,
when executed and delivered, shall constitute a valid and legally binding
obligation of Corixa in accordance with its terms, subject to laws of general
application relating to bankruptcy, insolvency and the relief of debtors, and
subject to general equity principles.

                  2.3 VALIDITY OF SHARES. The Shares being purchased by
Purchaser hereunder will, upon issuance pursuant to the terms hereof, be duly
authorized and validly issued, fully paid and nonassessable; provided, however,
that the Shares may be subject to restrictions on transfer under state and/or
federal securities laws as set forth herein or as otherwise required by such
laws at the time a transfer is proposed.

                  2.4 OFFERING. Assuming the accuracy of the representations and
warranties of Purchaser contained in Section 3 hereof, the offer, issue, and
sale of Shares are exempt from the registration and prospectus delivery
requirements of the 1933 Act, and the Shares are exempt from registration and
qualification under the registration, permit, or qualification requirements of
all applicable state securities laws.

                  2.5 SEC DOCUMENTS.

                           (a) As of the First Closing, Corixa will have
furnished to Purchaser the following documents, and the information contained in
such documents, as of their respective dates (or if amended, as of the date of
such amendment), will not contain any untrue statement of a material fact, and
will not omit to state any material fact necessary to make any statement, in
light of the circumstances under which such statement was made, not misleading:

such documents, as of their respective dates (or, if amended, as of the date of
amendment), will not contain any untrue statement of a material fact, or omit to
state a material fact necessary to make any statement, in light of the
circumstances under which such statement is made, not misleading.

         Corixa's most recent annual report on Form 10-K, together with its most
recent proxy statement for its Annual Meeting of Stockholders and any additional
Quarterly Reports on form 10-Q or Current Reports on Form 8-K filed after the
date of such annual report on Form 10-K but prior to the Second Closing.

furnished to Purchaser the following documents, and the information contained in
such documents, as of their respective dates (or, if amended, as of the date of

                  2.6 NO CONFLICT; NO VIOLATION. The execution, delivery and
performance of this Agreement and consummation of the transactions contemplated
hereby will not (a) conflict with any provisions of the Certificate of
Incorporation or Bylaws of Corixa; (b) result in any material violation or
default of, or permit the acceleration of any obligation under (in each case,
upon the giving of notice, the passage of time, or both), any material mortgage,
indenture, lease, agreement or other instrument, permit, franchise, license,
judgment, order, decree, law, ordinance, rule or regulation applicable to Corixa
or its properties.

                  2.7 CONSENTS AND APPROVALS. All consents, approvals, orders,
or authorizations of, or registrations, qualifications, designations,
declarations, or filings with, any governmental authority, required on the part
of Corixa in connection with the valid execution and delivery of this Agreement,
the offer, sale or issuance of the Shares, or the consummation of any other
transaction contemplated hereby have been obtained, or will be effective at the
Closing, except for notices required or permitted to be filed with certain state
and federal securities commissions after the Closing, which notices will be
filed on a timely basis.

                  2.8 ABSENCE OF CERTAIN DEVELOPMENTS. As of the Closing, since

Form 10-K or Quarterly Report on Form 10-Q referred to Section 2.5, except as
Corixa may specify in a Schedule of Exceptions provided to Purchaser promptly
before the Closing, Corixa shall not have (a) incurred or become subject to any
material liabilities (absolute or contingent) except current liabilities
incurred, and liabilities under contracts entered into, in the ordinary course
of business,

                                      -5-
<PAGE>
consistent with past practices; (b) mortgaged, pledged or subjected to lien,

material debts or obligations except in the ordinary course of business,
consistent with past practices; (d) suffered any extraordinary losses, or waived
any rights of substantial value; (e) entered into any material transaction other
than in the ordinary course of business, consistent with past practices; or (f)
otherwise had any material change in its condition, financial or otherwise,
except for changes in the ordinary course of business, consistent with past
practices, none of which individually or in the aggregate has been materially
adverse to Corixa.

         3.       REPRESENTATIONS AND WARRANTIES OF PURCHASER.

         Purchaser hereby represents and warrants to Corixa as follows:

                  3.1 AUTHORIZATION. All corporate action on the part of
Purchaser, its officers, directors and stockholders necessary for the
authorization, execution and delivery of this Agreement and the performance of
all Purchaser's obligations hereunder has been taken or will be taken prior to
Closing. This Agreement, when executed and delivered, shall constitute a valid
and legally binding obligation of Purchaser in accordance with its terms,
subject to laws of general application relating to bankruptcy, insolvency and
the relief of debtors, and subject to general equity principles.

                  3.2 INVESTMENT REPRESENTATIONS.

                           (a) Purchaser is acquiring the Shares for its own
account, not as nominee or agent, for investment and not with a view to, or for
resale in connection with, any distribution or public offering thereof within
the meaning of the 1933 Act.

                           (b) Purchaser understands that (i) the Shares have
not been registered under the 1933 Act by reason of a specific exemption
therefrom, that the Shares must continue to be held by Purchaser, and that
Purchaser must, therefore, bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
1933 Act or is exempt from such registration; (ii) the exemptions from
registration afforded by Rule 144 (the provisions of which are known to it)
promulgated under the 1933 Act depend on the satisfaction of various conditions,
and that, if applicable, Rule 144 may afford the basis for sales only in limited
amounts; (iii) each certificate representing the Shares will be endorsed with
the following legend:

                  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
         SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS (A) PURSUANT TO SEC
         RULE 144 OR (B) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID
         ACT COVERING SUCH SECURITIES OR (C) CORIXA RECEIVES AN OPINION OF
         COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO
         CORIXA, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION

                                      -6-
<PAGE>
         IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF
         SAID ACT."

And (iv) Corixa will instruct any transfer agent not to register the transfer of
any of the Shares unless the conditions specified in the foregoing legend are
satisfied.

                           (c) It has been furnished with such materials and has
been given access to such information relating to Corixa as it or its qualified
representative has requested and it has been afforded the opportunity to ask
questions of and receive answers from the management of Corixa regarding Corixa
and the Shares, all as it has found necessary to make an informed investment
decision.

                           (d) Purchaser is an "accredited investor" within the
meaning of Rule 501 of Regulation D promulgated under the 1933 Act and was not
organized for the specific purpose of acquiring the Shares.

                           (e) For purposes of the application of state
securities laws, Purchaser represents that it is a corporation organized and
existing under the laws of the state of Delaware.

         4.       CONDITIONS TO CLOSING.

                  4.1 CONDITIONS TO OBLIGATIONS OF PURCHASER. Purchaser's
