EXHIBIT 99.1

                                    AGREEMENT
                           FOR THE SUPPLY OF COMPOUNDS


         This Agreement is entered into as of October 15th, 2001 by and between
PFIZER INC, a Delaware corporation, and its Affiliates, having a principal place
of business at 235 East 42nd Street, New York, NY 10017 ("Pfizer") and ARRAY
BIOPHARMA INC. with an address at 3200 Walnut Street, Boulder Colorado 80301
("Array").

         WHEREAS, Pfizer is engaged in discovery, development and marketing of
pharmaceuticals for the treatment of human and animal diseases and is interested
in evaluating compounds which may be useful in this area;

         WHEREAS, Array is in the business of selling compounds and building
blocks; and

         WHEREAS, Pfizer wishes to purchase from Array and Array wishes to sell
to Pfizer, certain chemical compounds and building blocks ("Compounds"), for
animal and human pharmaceutical research and development, set forth in the list
("List") attached to and made part of this Agreement as Exhibit A, and amended
from time to time.

         NOW, THEREFORE, the parties agree as follows:

1.       Purchase and Sale.

         1.1      Pfizer, from time to time, shall select and purchase Compounds
                  on a plate-by-plate basis from (a) the List (b) a computerized
                  listing available from Array; or (c) Array supplied structure
                  lists of new Compounds.

         1.2      Array shall make a reasonable effort to supply each Compound
                  selected by Pfizer.

         1.3      Subject to Section 2.3 below, Array grants Pfizer a
                  non-exclusive license, under applicable Array intellectual
                  property, to make and use all Compounds in animal and human
                  pharmaceutical research and development (including, using as a
                  starting material or intermediate in the synthesis of other
                  substances), in perpetuity, with no further obligations to
                  Array, financial or otherwise, provided Pfizer has purchased
                  the Compounds according to the terms and conditions set forth
                  in Section 2. Array hereby grants Pfizer the option to obtain
                  an exclusive license, with the right to grant sublicenses,
                  under applicable Array intellectual property, to make, use and
                  sell Compounds that Pfizer activates in accordance with
                  Article 2 below ("Active Compounds").

         1.4      Pfizer shall not file, prosecute or maintain any patent
                  application or patent claiming a Compound unless Pfizer
                  designates such Compound as an Active Compound. Pfizer shall
                  have the right to seek and obtain patents on any Active


                                                 [***] CONFIDENTIAL TREATMENT OF
                                            REDACTED PORTIONS HAS BEEN REQUESTED


                                        2

                  Compounds and make disclosure required by law in such filings.
                  Array agrees to provide to Pfizer, all necessary information
                  upon Pfizer's request, to file, prosecute or maintain such
                  patents.

2.       Nomination of Active Compounds.

         2.1      Subject to Section 2.3 below, Pfizer may nominate a Compound
                  as an Active Compound by sending Array a written notice and a
                  one-time activation fee of [***] per Compound. Array will
                  thereupon either (a) advise Pfizer that such Compound cannot
                  be the subject of exclusive license under section 1.3 because
                  previous to Pfizer's nomination Array had granted a third
                  party Rights in such Compound, or (b) confirm that such
                  Compound is an Active Compound and provide Pfizer with the
                  synthetic protocols for it. Pfizer shall not be obligated to
                  make any further payment to Array with respects to its
                  exclusive license under section 1.3 for such Active Compound.

         2.2      If Array confirms any Compound as an Active Compound, Array
                  shall not thereafter make available or sell, or to share
                  information specifically relating to such Active Compound to
                  any third party.

         2.3      It is understood that Array is in the business of providing
                  combinatorial compound libraries to third parties, and except
                  as expressly provided herein, nothing herein shall prevent or
                  restrict Array from providing Compounds to third parties, or
                  from using the Compounds for any purposes. It is further
                  understood that Array may grant to third parties rights to
                  acquire licenses in the Compounds similar to those granted to
                  Pfizer hereunder; accordingly, Pfizer's right to designate any
                  particular Compound as an Active Compound, and Array's grant
                  of an exclusive license to Pfizer therefor, are limited to the
                  extent that Array has prior to designation of an Active
                  Compound granted a third party a license or other right with
                  respect to such a Compound.

         2.4      This Agreement shall not restrict or encumber Pfizer from
                  making, using, or selling analogs or derivatives of a
                  Compound, so long as such analogs and derivatives are not
                  Compounds.

3. Purchase Price. (a) The price for any Compound purchased by Pfizer shall be
agreed upon by both parties and set forth in the compound quotation
("Quotation") attached to and made part of this Agreement from time to time as
Exhibit B; (b) Pfizer shall pay within [***] days of receipt of Array's invoice.

4. Shipping and Documentation.

         4.1      Array shall process and ship each Compound selected by Pfizer
                  in accordance with Exhibit A.


                                                 [***] CONFIDENTIAL TREATMENT OF
                                            REDACTED PORTIONS HAS BEEN REQUESTED


                                        3


         4.2      Array will send to Pfizer Compound quantities in accordance
                  with Exhibit A.

         4.3      With each Compound, Array will supply to Pfizer information
                  regarding the Compound such as its structure, empirical
                  formula, molecular weight and other physical properties
                  regularly included in Array's reports.

         4.4      Array shall be responsible, at its own expense, for supplying
                  vials, labels and shipping containers for all Compounds.
                  Pfizer shall be responsible, at Pfizer's expense, for insuring
                  all Compounds selected by Pfizer. Array shall be responsible,
                  at Pfizer's expense, for shipping all Compounds using either
                  Federal Express, Account number [***] or United Parcel Service
                  - Ground, Account number [***].

5.       Liabilities and Responsibilities.

         5.1      Pfizer and Array each represents to the other that it has
                  expertise and experience in the analysis, synthesis, safety,
                  use and handling of chemicals. Neither party shall be
                  obligated to provide the other assistance, information or
                  reimbursement with respect to any inspection, investigation or
                  adverse finding by any federal, state or local governmental
                  agency. Pfizer and Array each indemnifies and holds harmless
                  the other, including its officers, directors, employees,
                  affiliates and sublicensees, from any claim, suit, liability
                  or expense, including, reasonable attorneys fees that such
                  other party may face as a result of damage to property
                  including the environment and death or injury to persons,
                  including the other party's employees resulting from any
                  aspect of its direct or indirect use of the information or
                  Compounds furnished to it by the other party under this
                  Agreement.

         5.2      Each party is an independent contractor and shall retain
                  complete control over and responsibility for its own
                  operations and employees. Nothing in this Agreement shall be
                  construed to constitute either party a partner, joint
                  venturer, agent or representative of the other. Neither party
                  shall have the right or authority to assume or create any
                  obligation on behalf of or in the name of the other, to accept
                  legal process for the other or to bind the other in any manner
                  whatever.

6.       Confidentiality.

         6.1      Array shall keep confidential any information specifically
                  relating to the purchase by Pfizer of Compounds and the
                  nomination by Pfizer of Compounds as Active Compounds, with
                  the same degree of care that Array uses with its own similar
                  confidential information. Once Array confirms a Compound as an
                  Active Compound, Array shall keep confidential any information
                  specifically relating to such Active Compound, with the same
                  degree of care that Array uses with its own similar
                  confidential information.


                                                 [***] CONFIDENTIAL TREATMENT OF

                                        4


         6.2      Pfizer shall keep confidential any information relating to
                  Compounds not nominated by Pfizer as Active Compound, with the
                  same degree of care as it uses with its own confidential
                  information.

         6.3      A party's non-disclosure obligations shall not apply to the
                  extent that such party can demonstrate that any information or
                  Compounds:

                           a.  was in its possession or control before the
                               other party disclosed it to such party; or

                           b.  is lawfully obtained from a third party
                               under no obligation of confidentiality to
                               the other party relative to it; or

                           c.  becomes publicly available through no fault
                               of such party..

         6.4      The provisions of this Section 6 to the contrary
                  notwithstanding, nothing in this Agreement shall be construed
                  as preventing Pfizer from seeking and obtaining patents on any
                  invention to which Pfizer believes itself to be entitled and
                  making all disclosures required by law in such filings.

         6.5      All obligations of Pfizer under this provision shall terminate
                  five (5) years from the date of the Agreement first set forth.

7.       Term, Extension and Termination.

         7.1      Unless sooner terminated or extended as provided below, this
                  Agreement shall expire [***] years from the date of execution
                  by both parties. At least [***] before the end of the term,
                  Pfizer may extend this Agreement for [***] by giving written
                  notice to Array.

         7.2      Either party may terminate this Agreement if the other party
                  fails in any material respect to perform or observe any term,
                  covenant or understanding contained in this Agreement, and
                  does not remedy such failure within [***] of being given
                  notice.
