                     NON-COMPETITION AND SEVERANCE AGREEMENT

         This Non-Competition and Severance Agreement (the "Agreement") is dated
as of November 29, 2001, and is entered into between Pharmion Corporation, a
Delaware corporation (the "Company"), and Michael Cosgrave (the "Employee").

         WHEREAS, the Employee is currently employed by the Company; and

         WHEREAS, the Employee and the Company desire to embody in this
Agreement the terms, conditions and benefits to be provided to the Employee in
the event of the Employee's termination of employment with the Company; and

         WHEREAS, this Agreement shall supersede all prior oral and written
agreements, arrangements and understandings relating to the terms and conditions
of severance pay in the event of Employee's employment termination without Just
Cause (as defined herein).

         NOW, THEREFORE, the parties hereby agree:

         Section 1. DEFINITIONS.

         (a) "Board" shall mean the Board of Directors of the Company.

         (b) "Just Cause" shall mean (with regard to the Employee's termination
of employment with the Company): (i) Employee has committed or engaged in
negligent or willful conduct that is likely to be detrimental to the Company;
(ii) Employee has engaged in acts which constitute theft, fraud, or other

disobeyed the reasonable and lawful directives of the Company' Chief Executive
Officer or the Company's President or Board; (iv) Employee has refused or is
unwilling to perform his/her job duties; (v) Employee has failed adequately to

demonstrated habitual absenteeism; (vii) Employee is substantially dependent on
alcohol or any controlled substance or violates any general Company policy with
regard to alcohol or controlled substances; (viii) Employee has engaged in acts
which constitute sexual or other forms of illegal harassment or discrimination;

loyalty to the Company; or (xi) Employee breaches any term of this Agreement or
any other material agreement between Employee and the Company or any of its

         Section 2. BENEFITS.

         (a) Severance Benefit. In the event that the Employee's employment is
terminated by the Company without Just Cause (other than by reason of death or
disability), the Employee shall continue to receive the Salary at the rate in
effect hereunder on the date of such termination (the "Termination Date")
periodically, in accordance with the Company's prevailing payroll practices, for
a period of twelve (12) months following the Termination Date (the "Severance
Benefit"); provided, however, that the payment of the Severance Benefit shall
immediately terminate, and the Company shall have no further obligations to the
Employee with respect thereto, in the event that the Employee violates any of
the provisions contained in Section 3 hereof. Payment of any amounts pursuant to
this Section 2(a) shall be expressly conditioned upon the Employee's execution
of a general waiver and release of claims against the Company and its officers,
directors, agents, and affiliates in a form acceptable to the Company.

         (b) Continuation of Benefits in the Event of Death. In the event the
Employee dies prior to receipt of the Employee's entire Severance Benefit, the
remaining portion of such Severance Benefit shall continue to be paid, in the
same form and at the same time as described in Section 2(a) above to the
Employee's spouse, or, if the Employee is not married on the date of death, to
the Employee's estate.

         (c) Mitigation/Set Off. (i) The Employee shall not be required to seek
other employment or to attempt in any way to reduce amounts payable to the
Employee pursuant to this Agreement.

         Section 3. RESTRICTIVE COVENANTS. The Employee acknowledges and agrees
that the agreements and covenants contained in this Section 3 are (i) reasonable
and valid in geographical and temporal scope and in all other respects, and (ii)
essential to protect the value of the Company's business and assets, and by his
employment with the Company, the Employee will obtain knowledge, contacts,
know-how, training and experience and there is a substantial probability that
such knowledge, know-how, contacts, training and experience could be used to the
substantial advantage of a competitor of the Company and to the Company's
substantial detriment. For purposes of this Section 3, references to the Company
shall be deemed to include its subsidiaries.

         (a) Non-Competition. The Employee covenants and agrees that during the
Employee's employment with the Company (the "Employment Period") and for a
period extending to the first anniversary of the Employee's termination of
employment for any reason (the "Restricted Period"), with respect to any State
or foreign country in which the Company is engaged in business at the time of
such termination, the Employee shall not, directly or indirectly, individually
or jointly, own any interest in, operate, join, control or participate as a
partner, director, principal, officer, or agent of, enter into the employment
of, act as a consultant to, or perform any services for any entity which
competes to a material extent with the business activities in which the Company
is engaged at the time of such termination or in which business activities the
Company has documented plans to become engaged in and as to which Employee has
knowledge at the time of Employee's termination of employment, or any entity in
which any such relationship with the Employee would result in the inevitable use
or disclosure of Confidential Information. Notwithstanding anything herein to
the contrary, this Section 3(a)

                                      -2-

<PAGE>

shall not prevent the Employee from acquiring as an investment securities
representing not more than one percent (1%) of the outstanding voting securities
of any publicly-held corporation.

         (b) Extension. If the Employee violates the provisions of Section 3(a)
above, the Employee shall continue to be bound by the restrictions set forth in
Section 3(a) until a period of one year has expired without any violation of
such provisions.

         (c) Blue Pencil. If any court of competent jurisdiction shall at any
time deem the duration or the geographic scope of any of the provisions of this
Section 3 unenforceable, the other provisions of this Section 3 shall
nevertheless stand and the duration and/or geographic scope set forth herein
shall be deemed to be the longest period and/or greatest size permissible by law
under the circumstances, and the parties hereto agree that such court shall
reduce the time period and/or geographic scope to permissible duration or size.

         Section 4. INJUNCTIVE RELIEF. Without intending to limit the remedies
available to the Company, the Employee acknowledges that a breach of any of the
covenants contained in Section 3 hereof may result in material irreparable
injury to the Company or its subsidiaries or affiliates for which there is no
adequate remedy at law, that it will not be possible to measure damages for such
injuries precisely and that, in the event of such a breach or threat thereof,
the Company shall be entitled to obtain a temporary restraining order and/or a
preliminary or permanent injunction, without the necessity of proving
irreparable harm or injury as a result of such breach or threatened breach of
Section 3 hereof, restraining the Employee from engaging in activities
prohibited by Section 3 hereof or such other relief as may be required
specifically to enforce any of the covenants in Section 3 hereof.
Notwithstanding any other provision to the contrary, the Restricted Period shall
be tolled during any period of violation of any of the covenants in Section 3(a)
hereof and during any other period required for litigation during which the
Company seeks to enforce this covenant against the Employee if it is ultimately
determined that such person was in breach of such covenants.

         Section 5. TAXES. The Company may withhold from any payments made under
this Agreement all applicable taxes, including but not limited to income,
employment and social insurance taxes, as shall be required by law.

         Section 6. SUCCESSORS AND ASSIGNS; NO THIRD-PARTY BENEFICIARIES.

         (a) The Company. This Agreement shall inure to the benefit of and be
enforceable by, and may be assigned by the Company to, any purchaser of all or
substantially all of the Company's business or assets, any successor to the
Company or any assignee thereof (whether direct or indirect, by purchase,
merger, consolidation or otherwise). The Company will require any such
purchaser, successor or assignee to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such purchase, succession or assignment had taken
place.

         (b) The Employee. The Employee's rights and obligations under this
Agreement shall not be transferable by the Employee by assignment or otherwise,
without the prior written consent of the Company; provided, however, that if the
Employee shall die, all amounts then payable to the Employee hereunder shall be
paid in accordance with the terms of

                                      -3-
<PAGE>

this Agreement to the Employee's devisee, legatee or other designee or, if there
be no such designee, to the Employee's estate.

         Section 7. WAIVER AND AMENDMENTS. Any waiver, alteration, amendment or
modification of any of the terms of this Agreement shall be valid only if made
in writing and signed by the parties hereto; provided, however, that any such
waiver, alteration, amendment or modification is consented to on the Company's
behalf by the Board. No waiver by either of the parties hereto of their rights
hereunder shall be deemed to constitute a waiver with respect to any subsequent
occurrences or transactions hereunder unless such waiver specifically states
that it is to be construed as a continuing waiver.

         Section 8. SEVERABILITY AND GOVERNING LAW. If any covenants or such
other provisions of this Agreement are found to be invalid or unenforceable by a
final determination of a court of competent jurisdiction (a) the remaining terms
and provisions hereof shall be unimpaired and (b) the invalid or unenforceable
term or provision hereof shall be deemed replaced by a term or provision that is
valid and enforceable and that comes closest to expressing the intention of the
invalid or unenforceable term or provision hereof. THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO
(WITHOUT GIVING EFFECT TO THE CHOICE OF LAW PRINCIPLES THEREOF) APPLICABLE TO
CONTRACTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE.

         Section 9. NOTICES.

         (a) Every notice or other communication relating to this Agreement
shall be in writing, and shall be mailed to or delivered to the party for whom
it is intended at such address as may from time to time be designated by it in a
notice mailed or delivered to the other party as herein provided, provided that,
unless and until some other address be so designated, all notices or
communications by the Employee to the Company shall be mailed or delivered to
the Company at its principal executive office, and all notices or communications
by the Company to the Employee may be given to the Employee personally or may be
mailed to Employee at the Employee's last known address, as reflected in the
Company's records.

         (b) Any notice so addressed shall be deemed to be given: (i) if
delivered by hand, on the date of such delivery; (ii) if mailed by courier, on
the first business day following the date of such mailing; and (iii) if mailed
by registered or certified mail, on the third business day after the date of
such mailing.

         Section 10. EFFECT OF AGREEMENT. This Agreement shall not be construed
as creating any contract of employment between the Company and the Employee and
nothing in this Agreement shall be construed to alter the Employee's status as
an "at-will" employee. The Employee shall not have any right to be retained in
the employ or service of the Company for any length of time by reason of this
Agreement, and this Agreement shall not affect the right of the Company to deal
with the Employee in all respects relating to the Employee's employment,
including the Employee's discharge, compensation, and conditions of employment.

         Section 11. SECTION HEADINGS. The headings of the sections and

this Agreement or of any term or provision hereof.

understanding and agreement of the parties hereto regarding the employment of
the Employee. This Agreement supersedes all prior negotiations, discussions,
correspondence, communications, understandings and agreements between the
parties relating to the subject matter of this Agreement.

                              EMPLOYMENT AGREEMENT

         that Pharmion may assign this Agreement to one of its subsidiaries or
         related companies and that Mr. Cosgrave may be employed by one of
         Pharmion's subsidiaries or related companies pursuant to this
         Agreement.

2.       START DATE AND DURATION

         Your employment will begin November 1, 2000, and shall continue
         indefinitely subject to termination in accordance with Sections 14, 18
         and 20 of this Agreement.

3.       JOB TITLE AND RESPONSIBILITIES

         You shall be required to undertake such duties as the Company specifies
         and which are consistent with your position within the Company. This
         may from time to time involve the provision of your services by the
         Company to other companies owned by or related to Pharmion.

         Your job title will be Vice President/Regional Director.

         Your duties will include coordination of the marketing and selling
         activities of distributors of Pharmion's products (including products
         licensed to Pharmion) in Greece, Turkey, the Middle East, Africa, Asia,
         Australia and New Zealand on behalf of Pharmion.

         You shall report to whomsoever the Company may nominate from time to
         time. Initially, you will report directly to the Company's President
         (currently Patrick Mahaffy). Unless otherwise expressly stated in this
         Agreement, all consents, approvals and authorizations which you are
         required to obtain from the Company shall be given by the President or
         such other person as Pharmion shall specify or the President shall
         nominate from time to time.

         Your duties and this appointment may be performed by you solely or
         jointly with whomsoever the Company may appoint.

         The Company may require that you do not perform any duties and/or do
         not appear at the Company's premises (or the premises of any of the
         Company's subsidiaries or related companies) during any period of
         suspension or while you are under notice of termination of your
         employment provided that you continue to be paid the salary and
         benefits to which you are entitled under this Agreement and provided
         that the period of any such requirement does not exceed three (3)
         months.

<PAGE>

         In particular, but without limitation, you are required to comply with
         the following while you are employed by the Company:

         (a)      Provision of Information

                  You shall keep the President promptly and fully informed (in
                  writing if so required) of your conduct of Pharmion's
                  business.

         (b)      Business Plans and Budgets

                  You shall attend meetings as required to discuss business
                  plans. You shall prepare annual budgets in a form to be agreed
                  by Pharmion to be submitted to Pharmion for approval by the
                  required deadline.

         (c)      Limits on entering into contracts

                  Without the advance approval of the President, you may not
                  conclude contracts for the sale of Company products (including
                  products licensed by the Company) on behalf of the Company or
                  any subsidiary or related company.

                  You shall not commit the Company or any of its subsidiaries or
                  related companies to any other contract or obligation
                  involving a financial commitment exceeding the relevant amount
                  authorized by a budget approved by Pharmion.

                  You shall not cause the Company or any of its subsidiaries or
                  related companies to enter into any commitment, contract or
                  arrangement otherwise than in the normal course of business
                  and within the scope of your normal duties.

         (d)      Credit

                  You shall not pledge the credit of the Company or the credit
                  of any of the Company's subsidiaries or related companies or
                  grant any security, charge, lien or encumbrance over any or
                  all of its or their assets.

         (e)      Guarantees

                  You shall not bind or purport to bind the Company or any of
                  the Company's subsidiaries or related companies in

                  any other person.

         (f)      Recruiting

                  You shall not engage any person as an employee, or as a
                  self-employed subcontractor or consultant, unless either such
                  recruitment has been authorized by the relevant budget or you
                  have obtained the prior written approval of Pharmion.

                                       2

<PAGE>

         (g)      Media Coverage

                  You shall not make or give any statement announcement or
                  interview to the press, a radio or television network or any
                  other medium of communication on any matter concerning the
                  Company, or any of the Company's subsidiaries or related
                  companies, or any past or present or prospective customer or
                  client of the Company without the prior written approval of
                  the President.

         (h)      Advertising

                  You shall comply with the Company's rules and procedures in
                  relation to the placement of any advertisement in any
                  newspaper, magazine or other medium, of communication.

4.       NORMAL PLACE OF WORK

         Initially, you may base your primary work office in either Malta or
         Thailand. However, because your duties will involve travel to
         customer's locations, you may be required to travel anywhere in the
         World as is necessary for the proper performance of your duties. It is
         envisioned that you will be required to spend the majority of your time
         outside of Malta and Thailand. The Company reserves the right to assign
         you to any of its other subsidiaries or related companies and/or
         require you to be based at any place in the World. You will be given at
         least 3 months' notice of any such change.

5.       WHOLE TIME AND ATTENTION

         During your employment with the Company you shall devote your best
         efforts to promoting Pharmion's business and may not, without the prior
         written consent of the Company (and even then subject to any terms and
         conditions the Company may reasonably impose), engage or be interested
         in (in either case, whether directly or indirectly) any other business
         or employment.

         During your working hours you shall devote your whole time and
         attention to your duties for Pharmion and shall not be engaged in any
         other activities without the Company's prior written consent.

         You may not hold more than 5% of the issued securities of any class of
         shares in the Company or any of its subsidiaries or related companies.

6.       CONFIDENTIAL INFORMATION

         You acknowledge that signing and complying with the Confidential
         Information and Invention Assignment Agreement ("Confidential
         Information Agreement"), attached as Appendix A, is a condition of your
         employment with the Company. You therefore agree to sign and comply
         with the Confidential Information Agreement and acknowledge that by
         beginning employment with the Company, you will be deemed to have
         signed and agreed to all provisions of the Confidential Information
         Agreement.

                                       3

<PAGE>

7.       NORMAL WORKING HOURS

         Due to the nature of your current assignment (and, in particular, the
         fact that your current duties require you to work at distributors'
         premises) you do not currently have any normal hours of work.

         You are required to work such hours as are necessary for the proper
         performance of your duties.

8.       SALARY

         Your basic salary will be at the rate of 150,000 pounds sterling per
         year. Your salary will be reviewed in accordance with the Company's
         procedures from time to time.

         Should you be required to pay (or to have withheld) income tax in any
         country in respect of your basic salary, the Company shall increase
         your basic salary to the rate at which your net after tax salary rate
         shall be US $225,000 per year. Any such increase shall not be regarded
         as an increase in basic salary for the purposes of calculating any
         entitlement to benefits (e.g., the Company's contributions to your
         personal pension scheme).

         The Company may arrange for payment of all or any part of your basic
         salary (or the provision of any benefit) by any of its subsidiaries or
         related companies in satisfaction of its obligations hereunder.

9.       RENTAL ALLOWANCE

         You will be paid a rental allowance at the rate of US $2,000 per month.
         This will be paid to you in the United Kingdom in pounds sterling (the
         sterling equivalent for each monthly payment being calculated using the
         Applicable Exchange Rate for the date of each such payment). For
         purposes of this Section 9, the "Applicable Exchange Rate" for a
         particular date shall be the spot rate specified in the UK Financial
         Times on the immediately preceding Quarter Day (the "Quarter Days"
         shall be January 1st, March 1st, June 1st and September 1st) or, if
         such Quarter Day falls on a Sunday, the following Monday. At your
         election and direction, the Company will directly deposit the monthly
         rental allowance payments into a UK bank account designated by you.

10.      TERMINATION PAYMENT OWED BY NEXSTAR PHARMACEUTICALS INTERNATIONAL LTD.

         You have informed the Company that pursuant to an employment contract
         between you and NeXstar Pharmaceuticals International Ltd (NeXstar),
         NeXstar will be obligated to pay you a termination payment (the
         "NeXstar Termination Payment") upon the termination of your employment
         with NeXstar. In the event that NeXstar fails and refuses to pay you
         the NeXstar Termination Payment, the Company, at its sole option, will

         The Company shall reimburse you all expenses reasonably and necessarily
         incurred by you in the proper performance of your duties in accordance
         with the Company's staff expenses policy as amended from time to time.
         Such reimbursement will be made within two (2) months of the date on
         which such expenses have been incurred provided that you supply the
         Company with evidence satisfactory to the Company that such expenditure
         has been properly incurred within one (1) month of the date on which
         such expenditure is incurred.

         All reimbursements of expenses shall be made directly into your
         nominated UK bank account in pounds sterling. Any expenditure incurred
         in another currency shall be converted to pounds sterling using the
         Applicable Exchange Rate for the date on which the expenditure has been
         incurred.

         If the Company advances to you any sums in anticipation of future
         expenses to be incurred, such sums are the property of the Company. You
         are required to repay immediately on demand the outstanding balance of
         any such advance against which expense claims have not been properly
         submitted within one (1) month of the date on which such sums are
         advanced to you. If you do not repay such outstanding sums, the Company
         is hereby irrevocably authorized to deduct the same (or any part
         thereof) from any payment due to you from the Company under Section 8
         or Section 9 above, or any money owed to you by the Company on or after
         termination of your employment (and such deduction shall be without
         prejudice to the Company's right to seek repayment by you of any part
         still outstanding thereafter).

12.      WORK PERMITS

         The Company shall assist you in any endeavors to acquire the necessary
         work, residential and other permits or visas required for this
         assignment and any further assignment and the Company shall reimburse
         you for any reasonable costs incurred in obtaining such permits within
         two (2) months on the date on which you incur such costs provided that
         you supply the Company with evidence satisfactory to the Company that
         such costs have been properly incurred within one (1) month of the date
         on which such expenses are incurred.

13.      HOLIDAY

         (a)      Entitlement

                  The Company's holiday year is the calendar year. In addition
                  to local public holidays (i.e., those applying to the
                  jurisdiction in which you are working on a particular day),
                  you are entitled to 22 working days' paid holiday per year to
                  be taken at times convenient to the Company.

                  During your first and last calendar years of employment with
                  the Company your holiday entitlement will be calculated at the
                  rate of 1.8 days for each complete calendar month of
                  employment with the Company in the Company's holiday year.

                                       5
<PAGE>

                  Your accrued holiday entitlement shall be calculated by
                  rounding up to the nearest half day.

         (b)      Procedures

                  You may not take holidays without the prior approval of the
                  Company.

                  Your accrued holiday entitlement may not be carried forward
                  from holiday year to holiday year without the prior written
                  approval of the Company (which will not normally be given).
                  Any holiday entitlement which has not been used by the end of
                  the holiday year or carried forward to the next holiday year
                  will be forfeited without pay.

         (c)      Termination of Employment

                  Except in the case of termination of your employment resulting
                  from your gross misconduct, the Company will compensate you
                  for any accrued but untaken holiday entitlement outstanding on
                  termination of your employment at the rate of 1/260th of your
                  annual basic salary for each accrued but untaken day of
                  holiday.

                  If you have taken in excess of your accrued holiday
                  entitlement on termination of your employment you must repay
                  to the Company the excess holiday pay paid to you at the rate
                  of 1/260th of your annual basic salary for each day's holiday
                  taken in excess of your entitlement. If you do not repay
                  immediately on demand such excess holiday pay the Company is
                  hereby irrevocably authorized to deduct such amount (or any
                  part thereof) from any money owed to you (including salary) by
                  the Company on or after termination of your employment (and
                  such deduction shall be without prejudice to the Company's
                  right to seek repayment by you of any part still outstanding
                  thereafter).

                  The Company reserves the right to insist that you take some,
                  all or none of any outstanding holiday entitlement during your
                  notice period. Your holiday entitlement will accrue during
                  your notice period.

                  absence due to sickness or injury you are required to complete
                  a self-certification form recording the duration of your
                  absence and the reasons for your absence. A copy of any such
                  self certification form must be faxed to the Company's
                  appropriate representative and will be retained in the
                  Company's records.

                  Any unauthorized absence: must be explained and failure to do
                  so may be treated as a disciplinary matter.

         (b)      Sick Pay

                  If you are absent from work due to sickness or injury and
                  comply with the requirements of Subsection 14(a) above
                  regarding notification you will continue to be paid 75% of
                  your basic salary for a maximum aggregate of 13 weeks in any
                  12 month period. Your benefits will be continued during this
                  13 week period (although the Company's pension contributions
                  will be based on your reduced basic salary during any such
                  period of absence).

                  The Company reserves the right to require you to be examined
                  at any time by an independent doctor of its choice and at its
                  expense and to cease payment of your basic salary forthwith if
                  it is advised by that doctor that you are fit to return to
                  work. Failure to attend any examination without reasonable
                  cause shall entitle the Company to cease payment of your basic
                  salary forthwith.

         (c)      Injury, Actionable Nuisance or Negligence caused by Third
                  Parties

                  negligence caused by a third party or third parties all
                  payments made to you under this Section by the Company shall
                  to the extent that compensation is recoverable from any third
                  party (or would be but for this Section) constitute a loan to
                  you from the Company and shall be repaid by you when and to
                  the extent that the Company requests such repayment.

                  You shall take such action as the Company may reasonably
                  require in connection with pursuing a claim against such third
                  party in respect of the event which caused the ill health or
                  injury in order to recover for the benefit of the Company the
                  costs of continuing your employment.
