Ms. Nicole Onetto, MD

Dear Nicole:

      This letter is to confirm our understanding with respect to your
employment with OSI Pharmaceuticals, Inc., its subsidiaries or affiliates (the
"Company").

      1. Employment. The Company will employ you, and you agree to be employed
by the Company as Executive Vice President, Oncology Division Head reporting to
Colin Goddard, Ph.D. The principal location at which you shall perform such
services shall be the Company's facility located in Boulder, CO. Your employment
hereunder shall commence on or about January 1, 2002 (the "Commencement Date")
and shall continue on an "at-will" basis, meaning that either you or the Company
may terminate your employment at any time and for any reason.

      2. Compensation.

            (a) Base Salary; Incentive Bonus. The Company shall pay you as your
compensation for your services and agreements hereunder a base salary payable at
the bi-weekly rate of $12,692, which annualized is $330,000 per year (the "Base

Beginning with calendar year 2002, you will also be eligible to participate in
the Company's annual performance-based incentive bonus plan as approved by the
Board solely in its discretion. You expressly acknowledge that you will not be
eligible to receive any bonus from the Company in respect of calendar year 2001,
which bonus, if any, shall be paid to you by Gilead Sciences, Inc.

            (b) Signing Bonus. You shall receive a $325,000 bonus (the "Signing
Bonus"), payable in one lump sum payment, less any amounts required to be
withheld under applicable law, upon the commencement of your employment with the
Company. If you voluntarily terminate your employment or the Company terminates
your employment for cause within one year of the Commencement Date, you shall be
required to reimburse the Company for $50,000; the amount you shall be required
to repay the Company shall be reduced 1/12th for each full month of service you
have completed as of the termination date.

            (c) Equity Compensation. Subject to approval by the Board, you shall

Incentive and Non-Qualified Stock Option Plan.

            (d) Benefits. You shall be entitled to participate in such employee
benefit plans as are generally made available for employees of the Company in
positions at a level comparable to you.

<PAGE>

            (e) Automobile. You will be entitled to a Company sponsored
automobile.

      3. Severance Compensation.

            (a) In the event that your employment hereunder is terminated by the
Company without "cause", and in exchange for your execution of a general release
of all claims against the Company:

                  (i) The Company will continue to pay you your Base Salary for
a period of twelve (12) months commencing on the effective date of such
termination.

            (b) In the event that the Company is sold or merged with another
Company resulting in a change of control (a "Change of Control"), and you
voluntarily terminate your employment for a "Good Reason" (as defined below) at
any time within six (6) months following a Change of Control transaction, you
will be entitled to receive from the controlling company in lieu of any further
salary and bonus payments to you for periods subsequent to the date of
termination, the salary described in subparagraph (a) above. In addition, your
stock options will vest immediately upon such event.

            (c) For purposes of this Section 3(b), "Good Reason" means (i)
decrease in your total compensation package, (ii) the assignment of duties or
responsibilities which are not commensurate with your position immediately prior
to the sale or Change of Control, or (iii) you are required to relocate to an
office or facility more than forty (40) miles from your present location or
forty (40) miles from your home.

            (d) If your employment with OSI is terminated within one year
(except for "cause") from the date of transaction between OSI and Gilead, you
will be entitled to a lump sum severance payment equal to your annual salary for
a period of twelve (12) months.

      4. Prohibited Competition. NOTE: Colorado statutes limit non-competes to
situations involving (i) protection of trade secrets or (ii) "executive and
management personnel," or "professional staff to executive and management
personnel."

            (a) Covenants Not to Compete. During the period in which you perform
services for or at the request of the Company (the "Term") and for a period of
two (2) years following the expiration or termination of the Term, whether such
termination is voluntary or involuntary, you shall not, without the prior
written consent of the Company:

                  (i) For yourself or on behalf of any other person or entity,
directly or indirectly, either as principal, agent, stockholder, employee,
consultant, representative or in any other capacity, own, manage, operate or
control, or be concerned, connected or employed by, or otherwise associate in
any manner with, engage in or have a financial interest in any business which
creates or develops products which are directly competitive with the products of
the Company in any geographic location in which the Company is then operating
(the "Restricted Territory"), except that nothing contained herein shall
preclude you from purchasing or owning securities of any such business if such
securities are publicly traded, and provided that your holdings do not exceed
three (3%) percent of the issued and outstanding securities of any class of
securities of such business; or

                                        2

<PAGE>

                  (ii) Either individually or on behalf of or through any third
party, solicit, diver or appropriate or attempt to solicit, divert or
appropriate, for the purpose of competing with the Company or any present or
future parent, subsidiary or other affiliate of the Company which is engaged in
a similar business as the Company, any customers or patrons of the Company, or
any prospective customers or patrons with respect to which the Company has
developed or made a sales presentation (or similar offering of services),
located within the Restricted Territory; or

                  (iii) Either individually or on behalf of or through any third
party, directly or indirectly, solicit, entice or persuade or attempt to
solicit, entice or persuade any other employees of or consultants to the company
or any present or future parent, subsidiary or affiliate of the Company to leave
the services or the Company or any such parent, subsidiary or affiliate for any
reason.

            (b) Reasonableness of Restrictions. You further recognize and
acknowledge that (i) the types of employment which are prohibited by this
Section 4 are narrow and reasonable in relation to the skills which represent
your principal salable asset both to the Company and to your other prospective
employers, and (ii) the specific but broad geographical scope of the provisions
of this Section 4 is reasonable, legitimate and fair to you in light of the
Company's need to market its services and sell its products in a large
geographic area in order to have a sufficient customer base to make the
Company's business profitable and in light of the limited restrictions on the
type of employment prohibited herein compared to the types of employment for
which you are qualified to earn your livelihood.

            (c) Survival of Acknowledgements and Agreements. Your
acknowledgements and agreements set forth in this shall survive the expiration
or termination of this Agreement and the termination of your employment with the
Company for any reason.

      5. Protected Information. You shall at all times, both during and after
any termination of this Agreement by either you or the Company, maintain in
confidence and shall not, without the prior written consent of the Company, use,
except in the course of performance of your duties for the Company, disclose or
give to others any Confidential and Proprietary Information. For purposes of
this Agreement, "Confidential and Proprietary Information" means confidential
and proprietary information of the Company which was disclosed to or developed
by you during the course of performing services for, or receiving training from,
the Company, and is not available to the public, including but not limited to
information and facts concerning business plans, customers, future customers,
suppliers, licensors, licensees, partners, investors, affiliates or others,
training methods and materials, financial information, sales prospects, client
lists, inventions, or any other scientific, technical, trade or business secret
of the Company or any third party provided to you or the Company under a
condition of confidentiality, provided that Confidential and Proprietary
Information shall not include information that is (1) in the public domain other
than through any fault or act by you, (2) known to you prior to its disclosure
to you in the course of your employment by the Company, or (3) lawfully
disclosed to you by a source other than the Company which source has the legal
right to disclose such information.

      6. Ownership of Ideas, Copyrights and Patents. You agree that all ideas,
discoveries, creations, manuscripts and properties, innovations, improvements,
know-how,

                                        3

<PAGE>

inventions, designs, developments, apparatus, techniques, methods, biological
processes, cell lines, laboratory notebooks and formulae which may be used in
the business of the Company, whether patentable, copyrightable or not, which you
may conceive, reduce to practice or develop during your employment with the
Company (collectively, the "Inventions"), alone or in conjunction with another,
or others and whether at the request or upon the suggestion of the Company, or
otherwise, shall be the sole and exclusive property of the Company, and that you
shall not publish any of the Inventions without the prior written consent of the
Company. You hereby assign to the Company all of your right, title and interest
in and to all of the foregoing. You further represent and agree that to the best
of your knowledge and belief none of the Inventions will violate or infringe
upon any right, patent, copyright, trademark or right of privacy, or any
constitute libel or slander against or violate any other rights of any person,
firm or corporation and that you will use your best efforts to prevent any such
violation. You agree that you will fully cooperate with the Company, its
attorneys and agents in the preparation and filing of all papers and other
documents as may be required to perfect the Company's rights in and to any of
such Inventions.

      7. Disclosure to Future Employers. You agree that you will provide, and
that the Company may similarly provide in its discretion, a copy of the
covenants contained in Sections 4, 5 and 6 of this Agreement to any business or
enterprise which you may directly, or indirectly, own, manage, operate, finance,
join, control or in which you participate in the ownership, management,
operation, financing or control, or with which you may be connected as an
officer, director, employee, partner, principal, agent, representative,
consultant or otherwise.

      8. Records. Upon termination of your relationship with the Company, you
shall deliver to the Company any property of the Company which may be in your
possession including products, materials, memoranda, notes, records, reports, or
other documents or photocopies of the same.

      9. No Conflicting Agreements. You hereby represent and warrant that you
have no commitments or obligations inconsistent with this Agreement and you
hereby agree to indemnify and hold the Company harmless against loss, damage,
liability or expense arising from any claim based upon circumstances alleged to
be inconsistent with such representation and warranty.

      10. Other. Based upon financial evaluation of the value in your unvested
Gilead options, OSI will be granting you 50,000 options of OSI common stock. In
this regard, you will also receive 10,000 shares of OSI common stock, redeemable
upon registration. Please note that a proportion of your sign-on bonus is
designed to address any personal income tax liabilities associated with the
grant of this stock.

      NOW, THEREFORE, in consideration of the foregoing premises, the provisions
and the respective agreements hereinafter set forth, the parties hereby agree as
follows:

SECTION 1. Distribution Agreement Payables. Demand for payment is hereby made by
Atari for all amounts due and owing under the Distribution Agreement as of the
date hereof, totaling $15,707,137, and IESA acknowledges that that sum is
currently due and payable from IESA to Atari.

SECTION 2. D&D Note Payable. Demand for payment is hereby made by Atari for all
amounts due and owing under the D&D Note as of the date hereof, totaling
$2,221,704.65 (which amount is inclusive of accrued interest through November 2,
2004) (the "D&D Payable"), and Interactive hereby acknowledges that that sum is
currently due and payable from Interactive to Atari under the D&D Note.
Interactive further acknowledges that on or before December 31, 2004, an
additional $1,619,084.25 (which amount is inclusive of accrued interest through
November 2, 2004) will become due and payable under the D&D Note (the
"Additional D&D Payable").

SECTION 3. Toys R' Us Note Payable. Demand for payment is hereby made by Atari
for all amounts due and owing under the Toys R' Us Note as of the date hereof,
totaling $2,676,306.68 (which amount is inclusive of accrued interest through

and payable from Interactive to Atari under the Toys R' Us Note.

SECTION 4. Paradigm Note Payable. Demand for payment is hereby made by Atari for
all amounts due and owing under the Paradigm Note as of the date hereof,
totaling $834,764.61 (which amount is inclusive of interest accrued from

is currently due and payable from Paradigm to Atari under the Paradigm Note.

SECTION 5. Assignment of Debt. (a) Atari hereby sells, assigns and transfers to
Interactive $15,707,137 of the IESA Debt for a purchase price of $15,707,137,
which is being paid by delivery of the Interactive Note. IESA acknowledges and
agrees to the assignment of the IESA Debt.

      (b) Atari hereby sells, assigns and transfers to Interactive the Paradigm
Note for a purchase price of $834,764.61, which is being paid by delivery of the
Interactive Note. Paradigm acknowledges and agrees to the assignment of the
Paradigm Note.

SECTION 6. Interactive Note. Atari agrees that, instead of seeking immediate
payment of the sums due under the D&D Note and the Toys R' Us Note, and in
payment of the purchase price of the IESA Debt and the Paradigm Note described
in Section 5, and instead of seeking payment on December 31, 2004 of the
Additional D&D Payable, Atari will accept the Interactive Note, which (a) will
be secured by shares of Atari common stock and certain trademarks owned by
Interactive, as provided in the Interactive Note and the related Collateral
Agency Agreement substantially in the form of Exhibit A hereto, (b) will be
guaranteed by IESA as provided in the

                                       2
<PAGE>

Guarantee attached to the Interactive Note, (c) gives Atari the right to make
payments of sums that currently are due, or in the future become due, to
Interactive, IESA, Mutimedia and Paradigm by applying those sums in reduction of
interest and principal payable under the Interactive Note, and (d) provides that
the balance that is due and payable after application of sums due from Atari to
Interactive will be due and payable on March 31, 2005. After the Interactive
Note is issued, Interactive will no longer have any obligations under the D&D
Note or the Toys R' Us Note. After the Interactive Note is issued, Paradigm
shall have no obligations under the Paradigm Note to Atari, and all obligations
of Paradigm thereunder shall be in favor of Interactive.

SECTION 7. Status of Distribution Agreement. Notwithstanding anything to the
contrary contained in Atari's notice letter to IESA, dated September 24, 2004,
Atari hereby agrees that, so long as Interactive is not in default of its
obligations under the Interactive Note, Atari will not exercise its right to
terminate the Distribution Agreement as a result of the non-payment of amounts
payable thereunder to which this Agreement relates.

SECTION 8. Application of Sums due to Interactive, IESA, Europe or Paradigm. (a)
Each of Interactive, IESA, Europe and Paradigm agrees that Atari may at any time
make payment of any sum owed by Atari to Interactive, IESA, Europe or Paradigm,
as the case may be, by applying the sum due to Interactive, IESA, Europe or
Paradigm in reduction of interest on, or principal of, the indebtedness
evidenced by the Interactive Note.

      (b) Atari will effect the application of a sum owed by Atari to
Interactive, IESA, Europe or Paradigm against interest in, or principal of, the
indebtedness evidenced by the Interactive Note by notifying the applicable one
of Interactive, IESA, Europe or Paradigm, notifying Interactive, as obligor
under the Interactive Note, of the amount that has been applied against the
indebtedness evidenced by the Interactive Note and identifying the payable from
Atari to Interactive, IESA, Europe or Paradigm, as the case may be, that was
applied.

      (c) If Atari applies a sum owed to IESA, Europe or Paradigm against
interest on, or principal of, the indebtedness evidenced by the Interactive
Note, Interactive will immediately become obligated to pay that sum to the
applicable one of IESA, Europe or Paradigm, provided that Interactive will not
be permitted to pay any such sum, and neither IESA, Europe nor Paradigm will
make any effort to collect any such sum, until all interest on, and principal
of, the indebtedness evidenced by the Interactive Note has been paid in full
(whether in cash, by application of sums due to Interactive, IESA, Europe or
Paradigm, or otherwise).

SECTION 9. Future Sums Due to Atari from Interactive. If after the date of this
Agreement, Atari advances any sums to Interactive, whether in the forms of loans
or otherwise, Atari may, at the time of each such advance, elect to include the
sum advanced in the principal amount of the Interactive Note, in which case, at
the time that sum is advanced by Atari to Interactive, the principal of the
indebtedness evidenced by the Interactive Note will be increased by the amount
of that sum, and the increased principal will bear interest from that date at
the rate provided in the Interactive Note, will be secured by the security for
Interactive obligations under the Interactive Note, and in every other way will
be subject to the terms and provisions of the Interactive Note.

                                       3

SECTION 10. Further Assurances. Each of the parties hereto shall perform such
further acts and execute such further documents as may reasonably be necessary
to carry out and give full effect to the provisions of this Agreement and the
intentions of the parties as reflected hereby. Each of IESA, Interactive, Europe
and Paradigm (each, a "Grantor") irrevocably constitutes and appoints Atari, and
any director, officer or agent thereof, with full power of substitution, as its
true and lawful attorney in fact with full irrevocable power and authority in
the place and stead of the Grantors to execute and deliver or file any documents
or instruments necessary or desirable to accomplish the purposes of this
Agreement, the Interactive Note or the Collateral Agency Agreement that are not

financing statements with respect to the Interactive Note, with or without any
Grantor's signature, or a photocopy of this Agreement or the Interactive Note in
substitution for a financing statement, as Atari may deem appropriate and to
execute in any Grantor's name any financing statements and amendments thereto
and continuation statements which may require any Grantor's signature. Upon the
occurrence and during the continuance of an Event of Default (as defined in the
Interactive Note), such attorneys in fact are authorized to sell, transfer,
pledge, license, lease, otherwise dispose of, make any agreement with respect to
or otherwise deal with any of the collateral granted by the Interactive Note in
such manner as is consistent with the Uniform Commercial Code as in effect in
the State of New York from time to time and as fully and completely as though
Atari were the absolute owner thereof for all purposes, and to do at
Interactive's expense, at any time, or from time to time, all acts and things
which Atari deems necessary to protect, preserve or realize upon such collateral
and Atari's security interest therein, in order to effect the intent of this
Agreement, all as fully and effectively as any Grantor might do.

SECTION 11. Governing Law; Jurisdiction. This Agreement shall be governed by and
construed according to the laws of the State of New York, without regard to the
conflict of laws provisions thereof that would apply the laws of any other
jurisdiction. Any dispute arising under or in relation to this Agreement shall
be resolved in a Federal or state court sitting in the Borough of Manhattan in
the State of New York, and each of the parties hereby submits irrevocably to the
exclusive jurisdiction of any such court with regard to any suit or proceeding
relating to such a dispute, agrees not to seek to change the venue of any such
suit or proceeding because of inconvenience of the forum or for any other
reason, and agrees that process in any such suit or proceeding may be served by
registered mail or in any other manner permitted by the rules of the court in
which the action or proceeding is brought. IESA irrevocably appoints Interactive

of, or otherwise relating to, this Agreement.

notice of change of address shall only be valid upon receipt).

SECTION 15. Delays or Omissions. No delay or omission to exercise any right,
power or remedy accruing to any party under this Agreement shall be deemed a
waiver of the right to exercise that right, power or remedy, and no waiver of a

of any other breach or default theretofore or thereafter occurring. Any waiver,
permit, consent or approval of any kind or character on the part of any party of
any breach or default under this Agreement, or any waiver on the part of any
party of any provisions or conditions of this Agreement, must be in writing and
shall be effective only to the extent specifically set forth in such writing.
All remedies, either under this Agreement or by law or otherwise, afforded to
any of the parties shall be cumulative and not alternative.

SECTION 16. Severability. If any provision of this Agreement is held by a court
of competent jurisdiction to be unenforceable under applicable law, then such
provision shall be excluded from this Agreement and the remainder of this
Agreement shall be interpreted as if such provision were so excluded and shall
be enforceable in accordance with its terms; provided, however, that in such
event this Agreement shall be interpreted so as to give effect, to the greatest
extent consistent with and permitted by applicable law, to the meaning and
