occurrence under this Section 6.3, the Consultant shall be given written notice
by the Company that it intends to terminate the Consultants engagement for Due

(or nonperformance), the Consultants engagement by the Company shall
automatically be terminated hereunder for Due Cause.

nor the Company shall have any further rights or obligations under this
Agreement, except as provided in Sections 7, 8 and 9.

The Consultant shall not, without the prior written consent of the Chief
Executive Officer of the Company, disclose such material, directly or
indirectly, to any party, who at the time of such disclosure is not an
Consultant or agent of any member of the Company Group, or, except in order to
carry out her duties under this Agreement, remove from the Company's premises
any notes or records relating thereto, copies or facsimiles thereof (whether
made by electronic, electrical, magnetic, optical, laser, acoustic or other
means), or any other property of any member of the Company Group.

The Consultant agrees that all material, together with all notes and records of
the Consultant relating thereto, and all copies or facsimiles thereof in the
possession of the Consultant (whether made by the foregoing or other means) are
the exclusive property of the Company.

Except in order to carry out his duties under this Agreement, the Consultant
shall not in any manner use any material of the Company Group, or any other
property of any member of the Company Group, in any manner not specifically

available to the Consultant on a non-confidential basis prior to her employment
with any member of the Company Group, or (iii) becomes available to the
Consultant on a non-confidential basis from a source other than any member of
the Company Group or any of its agents or customers, as such, provided that such
source is not bound by a confidentiality agreement with any member of the
Company Group or any of such agents or customers.

7.2 Promptly upon the request of the Company, the Consultant shall deliver to
the Company all material relating to any member of the Company Group in the
possession of the Consultant without retaining a copy thereof, unless, in the
opinion of counsel for the Consultant either returning such material or failing
to retain a copy thereof would violate any applicable Federal, state, local or
foreign law, in which event such confidential material shall be returned without
retaining any copies thereof as soon as practicable after such counsel advises
that the same may be lawfully done.

7.3 In the event that the Consultant is required, by oral questions,
interrogatories, requests for information or documents, subpoena, civil
investigative demand or similar process, to disclose any material relating to
any member of the Company Group, the Consultant shall provide the Company with
prompt notice thereof so that the Company may seek an appropriate protective
order and/or waive compliance by the Consultant with the provisions hereof;
provided, however, that if in the absence of a protective order or the receipt
of such a waiver, the Consultant is, in the opinion of counsel for the
Consultant compelled to disclose material not otherwise disclosable hereunder to
any legislative, judicial or regulatory body, agency or authority, or else be
exposed to liability for contempt, fine or penalty or to other censure, such
material may be so disclosed.

and benefits provided for in this Agreement, and are a material
reason for such payment.

Consultant of any of the provisions of Sections 7 or 8 of this Agreement, the
Consultant hereby consents and agrees that the Company shall be entitled to
pre-judgment injunctive relief or similar equitable relief restraining the
Consultant from committing or continuing any such breach or threatened breach or
granting specific performance of any act required to be performed by the

actual damage or that money damages would not afford an adequate remedy and

                              EMPLOYMENT AGREEMENT

THIS AGREEMENT (the "Agreement") is made and effective as of December 31, 2002,
by and between Bioenvision, Inc, a Delaware Corporation (the "Company"), and
Christopher B. Wood, M.D. (the "Executive").

WHEREAS, the Company desires to continue to retain the Executive in its employ
as the Chairman of the Board and Chief Executive Officer of the Company for the
period provided in this Agreement, and the Executive has agreed to continued
employment with the Company in accordance with the contractual terms and
conditions set forth below; and

WHEREAS, this Agreement is intended to, and shall, set forth the definitive
agreement of the parties.

NOW, THEREFORE, for and in consideration of these recitals and premises, and the
respective promises, covenants and agreements contained herein, and intending to
be legally bound hereby, the parties hereto agree as follows:

      Section 1. Employment. The Company hereby employs the Executive, and the
Executive hereby accepts such employment with the Company, for the term of
employment set forth in Section 2 hereof, all upon the terms and conditions
hereafter set forth.

      Section 2. Term. Employment shall be for a term commencing on December 31,
2002 and, subject to prior termination under Section 8, Section 9, Section 10,
Section 12 or Section 13 hereof expiring on the one-year anniversary of such
date (December 31, 2003). Notwithstanding the previous sentence, the term of
this Agreement automatically shall be extended for additional one-year terms
upon the terms and conditions set forth herein, unless either party to this
Agreement gives the other party written notice (delivered in accordance with
Section 21 hereof and at least 90 days prior to December 31, 2003 or such later
termination date or dates as may be applicable to any extended term) of such
party's intention not to further extend the term of this Agreement. For purposes
of this Agreement, any reference to the "term" of this Agreement shall include
the original term and any extension thereof.

      Section 3. Duties of the Executive. The Executive shall serve as the
Chairman of the Board and Chief Executive Officer of the Company. The Executive
shall perform such executive duties as a Chairman of the Board and Chief
Executive Officer would normally perform or as otherwise specified in the
By-Laws of the Company as in effect on the date of this Agreement, and shall
perform in addition thereto, such other reasonable duties as the Board of
Directors of the Company (together with any applicable sub-committee or
sub-committees thereof, the "Board") may request consistent with Executive's
position and title. Except as may otherwise be approved in advance by the Board
and except during vacation periods and periods of absence due to sickness,
personal injury or other disability, the Executive shall devote all of his
working time and his best efforts to the performance of his duties hereunder.
Both parties hereto contemplate and agree that at some time during the term
hereof it may be in the best interests of the Company to appoint another person
as Chief Executive Officer of the Company in which case Executive shall act, on
a full-time basis, solely as Chairman of the Board. Notwithstanding the
foregoing, nothing contained herein shall preclude the Executive from (a)
serving on the boards of directors of other companies or

<PAGE>

organizations with the approval of the Board (not to be unreasonably withheld)
or serving on the boards of directors of not-for-profit companies or
organizations without the approval of the Board, (b) investing in and managing
passive investments, or (c) pursuing his personal, financial and legal affairs
provided that such activity does not materially interfere with the performance
of the Executive's obligations hereunder.

      Section 4. Compensation.

            (a)   For the period commencing on the date of this Agreement, the
                  Executive's base salary shall be $225,000 (and during the term
                  of this Agreement, not less than $225,000) on an annualized
                  basis. During the term of the Agreement, the Executive's
                  salary shall be reviewed at least annually by the Board to
                  determine whether any further increase is warranted and
                  appropriate. Except as set forth in this Section 4, such
                  compensation shall be payable at the times and in the manner
                  consistent with the Company's general policies regarding
                  compensation of executive employees, but in no event less
                  frequently than twice each calendar month.

            (b)   The Company hereby grants and issues to the Executive,
                  incentive stock options (subject to stockholder approval of
                  the related option plan, otherwise such options shall be
                  non-qualified stock options under the Internal Revenue Code)
                  with terms commensurate with the terms of options previously
                  issued to the Company's management to purchase 500,000 shares
                  of common stock at an exercise price equal to $1.45 (the
                  average of the high and low bid price of shares of the
                  Company's common stock on the date hereof (the "Grant Date"));
                  166,667 of which options vest on each of the first, second and
                  third anniversaries of December 31, 2002, or earlier upon
                  Executive's departure for good reason (pursuant to one or more
                  of the events set forth in Sections 9(i) or 9(ii)), a Change
                  of Control (as defined in Section 9) or termination other than
                  for Cause (as defined in Section 8). If Executive resigns
                  other than for good reason, Executive shall forfeit all
                  unvested stock options issuable hereunder as of the effective
                  date of such resignation. If Executive is terminated for
                  Cause, Executive shall forfeit all vested and unvested stock
                  options issued or issuabe hereunder as of the effective date
                  of such termination. If a Change of Control (as defined under
                  Section 9) occurs which prevents any incentive stock options
                  of Executive from receiving favorable tax treatment under
                  Section 422 of the Internal Revenue Code of 1986, Executive
                  shall be held harmless from any loss of such favorable tax
                  treatment.

            (c)   In addition to the base salary provided by Section 4(a) hereof
                  and the incentive stock options provided in Section 4(b)
                  hereof, the Executive shall be eligible annually to receive
                  any incentive bonus (the "Bonus") that the Board may grant to
                  him based on the Company's executive compensation plan then in
                  effect, based on the Board's assessment of the Executive's
                  individual performance, which decision shall be made by the
                  Board in its sole discretion. The Board shall give written
                  notice to the Executive of the grant of any such Bonus and the
                  amount thereof upon direction of the Board. Such Bonus shall
                  be payable on the next date on which the Executive is entitled
                  to receive a payment of his base compensation. The Board may
                  from time to time

<PAGE>

                  authorize such additional compensation to the Executive, in
                  cash, property, options or warrants as the Board may determine
                  in its sore discretion to be appropriate. Payment of any
                  bonus, if any, is in the sole and absolute discretion of the
                  Board.

      Section 5. Executive Benefits.

            (a)   In addition to the compensation described in Section 4, the
                  Company shall make available to the Executive and his eligible
                  dependants such benefits which are comparable to those
                  provided to other executive and management employees of the
                  Company, including without limitation, any medical, group
                  hospitalization, health, dental care or sick leave plan, life
                  or other insurance or death benefit plan, travel or accident
                  insurance or other present or future group employee benefit
                  plan or program of the Company for which key executives are or
                  shall become eligible.

            (b)   The Executive shall be entitled to 4 weeks paid vacation per
                  year, which shall be pro-rated for partial years. The
                  Executive may carry over from year to year up to 1 month of
                  unused vacation time. Notwithstanding anything herein to the
                  contrary, the Executive may not take more than two (2) weeks
                  vacation during any twelve (12) week period without the prior
                  written permission of the Board, which shall not be
                  unreasonably withheld. Upon a Change of Control (as defined in
                  Section 9), Executive promptly shall receive a one-time cash
                  payment for accrued vacation time at his then-current base
                  salary for up to 1 month of unused vacation time.

      Section 6. Expenses. The Company shall also pay or reimburse the Executive
for all reasonable and necessary expenses incurred by the Executive in
connection with his duties on behalf of the company in accordance with the
general policies of the Company and his employment by the Company pursuant to
this Agreement.

      Section 7. Place of Performance. In connection with his employment by the
Company, unless otherwise agreed by the Executive, the Executive shall be based
at the principal executive offices of the Company in New York City, except for
travel reasonably required for Company business, provided that for so long as in
management's judgment it is in the Company's best interests for Executive to be
located in the U.K. to manage the European development of the Company's
products, Executive shall be based at the Company's offices in the U.K. (the
"Place of Performance").

      Section 8. Termination. (a) The Company may terminate Executive's
employment hereunder for "Cause" which shall mean:

            (a) (1) The Executive is indicted for any crime involving moral
            turpitude or punishment by imprisonment;

            (b) (2) Executive's commission of an act of fraud;

            (c) (3) Executive's continuing repeated willful failure or refusal
            to perform his duties as required by this Agreement, provided, that
            termination of Executive's employment pursuant to this subparagraph
            (c) shall not constitute valid

<PAGE>

            termination for Cause unless Executive shall have first received
            written notice from the Board stating with reasonable specificity
            the nature of such failure or refusal and affording Executive at
            least fifteen (15) days to correct the act or omission complained
            of;

            (d) (4) Gross negligence, insubordination, or material violation by
            Executive of any duty of loyalty to the Company or any other
            material misconduct on the part of Executive; or

            (e) (5) A material breach of this Agreement by the Executive.

(b) In addition, the Company may terminate Executive's employment hereunder
without "Cause" (as defined in Section 8(a) above).

      Section 9. Resignation. (a) In the event that during the term of this
Agreement:

                  Executive's base salary below the minimum amount specified in
                  Section 4(a) without the Executive's prior written consent;

the occurrence of any such event of his election to resign and terminate this
Agreement effective immediately upon receipt of such notice (delivered in
accordance with Section 21 hereof), or effective upon such other date (not later

such notice (the "Effective Date") and Executive shall receive the payments and
other compensation provided in Section 4(b) and Section 11.

<PAGE>

            (b)   In addition to the foregoing, Executive shall have the right
                  to resign other than such resignation as would constitute a

                  multiplied by the Executive's base salary pursuant to Section
                  4.

            (b)   Options. Notwithstanding any provision to the contrary in any
                  option agreement or other agreement or in any plan, except for
                  a termination for Cause pursuant to Section 8 or a resignation
                  by Executive under Section 9 which does not constitute a
                  Permitted Resignation or does not occur upon a Change of
                  Control, all of the Executive's outstanding stock options
                  shall immediately vest and become exercisable and the

      Section 15. Indemnification. To the maximum extent permitted under the
corporate Laws of the State of Delaware, By-Laws and Certificate of
Incorporation of the Company as in effect from time to time:

            (a)   the Executive shall be indemnified and held harmless by the
                  Company, as provided under such corporate laws or such
                  By-Laws, as applicable, for any and all actions taken or
                  matters undertaken, directly or indirectly, in the performance
                  of his duties and responsibilities under this Agreement or
                  otherwise on behalf of the Company, and

<PAGE>

            (b)   without limiting clause (a), the Company shall indemnify and
                  hold harmless the Executive from and against (i) any claim,
                  loss, liability, obligation, damage, cost, expense, action,
                  suit, proceeding or cause of action (collectively, "Claims".)
                  arising from or out of or relating to the Executive's
                  performance as an officer, director, employee or agent of the
                  Company or any of its affiliates or in any other capacity,
                  including, without limitation, any fiduciary capacity, in
                  which the Executive serves at the request of the Company, and
                  (ii) any cost or expense (including, without limitation, fees
                  and disbursements of counsel) (collectively, "Expenses")
                  incurred by the Executive in connection with the defense or
                  investigation thereof. If any Claim is asserted or other
                  matter arises with respect to which the Executive believes in
                  good faith the Executive is entitled to indemnification as
                  contemplated hereby, the Company shall pay the Expenses
                  incurred by the Executive in connection with the defense or
                  investigation of such Claim or matter (or cause such Expenses
                  to be paid) on a monthly basis, provided that the Executive
                  shall reimburse the Company for such amounts, plus simple
                  interest thereon at the then current prime rate as reported in
                  the Wall Street Journal as in effect from time to time,
                  compounded annually, if the Executive shall be found, as
                  finally judicially determined by a court of competent
                  jurisdiction not to have been entitled to Indemnification
                  hereunder. Notwithstanding the foregoing, the Company's
                  obligation to indemnify Executive hereunder shall be subject
                  to (i) timely notification by Executive hereunder of any
                  claims that are subject to indemnification under this Section
                  15 (and any failure of Executive to so notify the Company
                  which shall cause the Company to compromise any defense to
                  such claim will cause the Company not to be obligated to
                  indemnify Executive hereunder) and (ii) the Company will have
                  the right to undertake the defense of and compromise, settle
                  or otherwise dispose of any claim for which it may be subject
                  to indemnify Executive hereunder.

agreements, either oral or written, between the parties hereto with respect to
the subject matter hereof, and contains all of the covenants and agreements
between the parties with respect to such subject matter, and Executive has
received legal counsel regarding the entirety of the Agreement.

      Section 17. Withholding of Taxes. The Company may withhold from any
amounts payable under this Agreement all foreign, federal, state, city or other
taxes as the Company is required to withhold pursuant to any law or government
regulation or ruling.

      Section 18. Successors and Binding Agreement.

            (a)   The Company will reasonably require any successor (whether
                  direct or indirect, by purchase, merger, consolidation,
                  reorganization or otherwise) to all or substantially all of
                  the business or assets of the Company by agreement in form and
                  substance satisfactory to the Executive acting reasonably,
                  expressly to assume and agree to perform this Agreement in the
                  same manner and to the same extent the Company would be
                  required to perform if no such succession had taken place.

<PAGE>

                  the business or assets of the Company whether by purchase,
                  merger, consolidation, reorganization or otherwise (and such
                  Successor shall thereafter be deemed the "Company" for the
                  purposes of this Agreement).

            (b)   This Agreement will inure to the benefit of and be enforceable
                  by the Executive's personal or legal representatives,
                  executors, administrators, successors, heirs, distributes and
                  legatees.

            (c)   The rights of the Company under this Agreement may without the
                  consent of Executive, be assigned by the Company in its sole
                  and unfettered discretion (i) to any person, firm,
                  corporation1 or other business entity which at any time,

                  indirectly, acquires all or substantially all of the assets or
                  business of the Company, or (ii) to any subsidiary or
                  affiliate of the Company (the "Company Group"), or any
                  transferee, whether by purchase, merger or otherwise, which

performance of this Agreement will be governed by and construed in accordance
with the substantive laws of the State of New York, without giving effect to the
principles of conflict of laws of such State.

Agreement is held to be illegal, invalid or unenforceable under any present or
future law, and if the rights or obligations of the parties under this Agreement
would not be materially and adversely affected thereby, such provision shall be
fully separable, and this Agreement shall be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part thereof,
the remaining provisions of this Agreement shall remain in full force and effect
and shall not be affected by the illegal, invalid or unenforceable provision or
by its severance therefrom, and, in lieu of such illegal, invalid or

expiration, will survive any termination or expiration of this Agreement or the
termination of the Executive's employment for any reason whatsoever.

      Section 23. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing signed by the Executive and the Company. No waiver by either party

Act of 1976, 17 U.S.C. 1 et seq. In the event of publication of such materials,
Executive understands that since work is a "work made for hire" the Company will
solely retain and own all rights in such materials, including right of
copyright.

      Section 29. Non-Solicitation and Non-Competition. Executive shall not,
while employed by the Company and during the six month period following the date

                  employee of the Company to leave the employ of the Company;

            (ii)  employ, or solicit for employment, on his behalf or on behalf
                  of any other person (other than the Company), any person that
                  is or was at any time an employee of the Company (excluding
                  clerical employees); (provided, however, that the foregoing
                  restriction shall cease to apply to a former employee of the
                  Company months after he ceases to be employed by the Company);
                  or

            (iii) take any other action detrimental to the relationship of the
                  Company with its employees, customers or suppliers.

In addition to the foregoing, while employed by the Company, Executive shall not

association (including, without limitation, as a shareholder partner, director,
officer, employee, consultant, sales representative, supplier, distributor,
agent or lender) in or with any person engaged in a business in the Specified
Areas that is in competition with the Company, provided, however, that the
foregoing shall not prohibit Executive from owning securities of any publicity
traded company that is engaged in any such business as long as Executive does
not own at any time 5% or more of any class of the equity securities of such
company.

            For purposes of the foregoing, the "Specified Areas" means (specify
            geographic area in which the Company conducts business).

law for any breach of any of the covenants contained in Section 25, 26, 27, 28,
29, 30 hereof may be inadequate. Accordingly, the Company shall be entitled
(without the necessity of showing any actual damage or posting a bond or
furnishing other security) to specific performance or any other mode of
injunctive and/or other equitable relief to enforce its rights under Sections or
any other relief a court might award, such rights to be cumulative with and not
exclusive of any other remedy.

IN WITNESS WHEREOF, the parties hereof have executed this Agreement as of the
