                        Annual Meeting of Stockholders
                          To Be Held On June 21, 2001

                                 INTRODUCTION


General

This Proxy Statement is being furnished to stockholders of Nexell Therapeutics
Inc., a Delaware corporation (the "Company"), in connection with the
solicitation of proxies by the Company's Board of Directors for use at the
Annual Meeting of Stockholders to be held at the Doubletree Hotel, 90 Pacifica
Avenue, Irvine, California on Thursday, June 21, 2001 at 9:00 a.m., Pacific
Daylight Time, and any and all adjournments or postponements thereof.  The cost
of the solicitation will be borne by the Company.

It is expected that this Proxy Statement and the accompanying proxy card will be
first mailed to stockholders on or about May 7, 2001.

Matters to be Considered at the Annual Meeting

At the Annual Meeting, the stockholders will be asked to consider and vote upon
the following proposals:

     1.   To elect a Board of eight directors;

     2.   To increase the number of shares of Common Stock issuable under the
          Company's 1997 Incentive and Non-Incentive Stock Option Plan from
          1,312,500 to 2,262,500;

     3.   To ratify the appointment of KPMG LLP as independent auditors of the
          Company for the year ending December 31, 2001; and

     4.   To transact such business as may properly come before the Annual
          Meeting or any adjournment or postponement thereof.



                                       1

Voting at the Annual Meeting

Stockholders of record of the Company's common stock, $.001 par value (the
"Common Stock") at the close of business on April 23, 2001 (the "Record Date")
are entitled to notice of and to vote at the Annual Meeting, each such holder
being entitled to one vote per share on each matter to be considered at the
Annual Meeting.  On the Record Date, there were 20,925,509 shares of Common
Stock issued and outstanding.  Holders of the Company's Series A Preferred Stock
and Series B Preferred Stock are not entitled to vote at the Annual Meeting.

The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Common Stock entitled to vote at the
Annual Meeting (10,462,755 shares outstanding of the 20,925,509 shares
outstanding) is necessary to constitute a quorum at the Annual Meeting.

The election of each of the eight nominees identified in this Proxy Statement
will require the affirmative vote of a plurality of the shares of Common Stock
present in person or represented by proxy at the Annual Meeting and entitled to
vote.

Ratification of the appointment of KPMG LLP as independent auditors of the
Company for the year ending December 31, 2001 and approval of the amendment to
the Company's 1997 Incentive and Non-Incentive Stock Option Plan will each
require the affirmative vote of the holders of a majority of the shares of
Common Stock present in person or represented by proxy at the Annual Meeting and
entitled to vote.

If the enclosed proxy card is properly executed and returned to the Company
prior to voting at the Annual Meeting, the shares represented thereby will be
voted in accordance with the instruction marked thereon, subject to the
following conditions:

     Election of Directors

Shares represented by a proxy marked "WITHHOLD AUTHORITY" to vote for (i) all
eight nominees or (ii) any individual nominee(s) for election as directors and
not otherwise "FOR" the other nominees will not be counted in determining
whether a plurality vote has been received for the election of directors.  In
the absence of instructions, shares represented by a proxy will be voted FOR all
of the eight nominees.  In instances where brokers are prohibited from
exercising discretionary authority for beneficial owners who have not returned
proxies ("broker non-votes"), those shares will be disregarded and therefore
will have no effect on the outcome of the vote.

     Other Proposals

Shares represented by a proxy marked "ABSTAIN" on any other proposal will not be
counted in determining whether the requisite vote has been received for such
proposal.  In the absence of instructions, shares represented by a proxy will be
voted FOR all of the proposals set forth in the Notice of Annual Meeting and at
the discretion of the proxy holders on any other matters that may properly come
before the Annual Meeting.  In instances of broker non-votes, those shares will
not be included in the vote totals, and therefore will have no effect on the
outcome of the votes on the proposals.

                                       2


Voting by Proxy

Stockholders of record (that is, stockholders who hold their shares in their own
name) can vote any one of three ways:

     (1)  By Mail: Sign, date and return your proxy card in the enclosed
          postage-paid envelope. If you sign and return your proxy card but do
          not give voting instructions, the shares represented by that proxy
          will be voted as recommended by the Board of Directors.

     (2)  By Telephone: Call the toll-free number on your proxy card to vote by
          phone. You will need to follow the instructions on your proxy card and
          the voice prompts.

     (3)  By Internet: Go to the web site listed on your proxy card to vote
          through the Internet. You will need to follow the instructions on your
          proxy card and the web site. If you vote through the Internet, you may
          incur telephone and Internet access charges.

If you vote by telephone or Internet, your electronic vote authorizes the named
proxies in the same manner as if you signed, dated and returned your proxy card.
If you vote by telephone or the Internet, you should not return your proxy card.

If your shares are held in the name of a bank, broker or other holder of record
(that is "street name"), you will receive instructions from the holder of record
that you must follow in order for your shares to be voted.  Telephone and
Internet voting also will be offered to stockholders owning shares through most
banks and brokers.


Changing Your Vote

You may change your vote at any time before the proxy is exercised. If you voted
by mail, you may revoke your proxy at any time before it is voted by executing
and delivering a timely and valid later-dated proxy, by voting by ballot at the
meeting or by giving written notice to the Secretary of the Company. If you
voted by telephone or the Internet you may also change your vote with a timely
and valid later telephone or Internet vote, as the case may be. Attendance at
the meeting will not have the effect of revoking a proxy unless you give proper
written notice of revocation to the Secretary before the proxy is exercised or
you vote by written ballot at the meeting.

                                       3

                                  PROPOSAL 1

                             ELECTION OF DIRECTORS


Board of Directors of the Company

The Bylaws of the Company provide that the number of directors shall be not less
than three nor more than fifteen. The Board of Directors has fixed the current
size of the Board at eight. Effective September 29, 2000, L. William McIntosh
resigned as a director. Effective October 10, 2000, Daniel Levitt, M.D., Ph.D.
was elected as a director by the Board of Directors. Effective December 4, 2000,
Donald G. Drapkin resigned from the Board. Effective March 1, 2001, William A.
Albright, Jr. was elected as a director by the Board of Directors. There are no
vacancies on the Board.

At the Annual Meeting, an eight person Board of Directors is to be elected, to
hold office until the next Annual Meeting of Stockholders and until their
successors are duly elected and qualified.  Unless otherwise specifically
directed by stockholders executing proxies, it is intended that all proxies in
the accompanying form received in time for the Annual Meeting will be voted FOR
the election of the eight nominees named below, all of whom are current
directors of the Company.

In the event any nominee should become unavailable for election for any
presently unforeseen reason, it is intended that the proxies will be voted FOR
such substitute nominee as may be designated by the present Board of Directors.

The Company, current directors Richard L. Dunning and Eric A. Rose, M.D., now
former directors Donald G. Drapkin, Lindsay A. Rosenwald, M.D. and Lawrence D.
Fink, Paramount Capital Asset Management Inc. and Baxter Healthcare Corporation
("Baxter") are parties to a Voting Agreement dated December 17, 1997 (the
"Voting Agreement"), pursuant to which all parties agreed to vote all of their
Common Stock in favor of one Baxter-nominated director.  Victor W. Schmitt has
been elected a director pursuant thereto.  In addition, Baxter has agreed to
vote all of its Common Stock in favor of the nominees for director recommended

Stock Option Plans

Beginning in July 1990, the Company has maintained the following stock option
plans: 1990 Incentive and Non-Incentive Stock Option Plan (the "1990 Plan"),
1997 Incentive and Non-Incentive Stock Option Plan (the "1997 Plan"), and 1998
Non-Incentive Stock Option Plan (the "1998 Plan"), (collectively the "Stock
Option Plans") and 1995 Directors' Stock Option Plan (the "1995 Directors'
Plan").

The Stock Option Plans are administered by the Compensation Committee of the
Board of Directors, which acts as the Stock Option Committee (the "Option
Committee"). The Option Committee is currently comprised of Richard L. Casey and
Joseph A. Mollica, Ph.D.

The purpose of the Stock Option Plans is to further the growth and development
of the Company by encouraging selected employees, directors and other persons
who contribute and are expected to contribute materially to the Company's
success to obtain a proprietary interest in the Company through the ownership of
its Common Stock, thereby providing such persons with an added incentive to
promote the best interests of the Company and affording the Company a means of
attracting persons of outstanding ability to its service. Approximately 100
employees of the Company and an indeterminate number of consultants and others
are eligible to participate in the Stock Option Plans.

     1990 Plan

The 1990 Plan was adopted in July 1990 and no further options could be granted
after July 2000. Under the 1990 Plan, 600,000 shares of Common Stock were
reserved for issuance upon exercise of either incentive or non-incentive
options, which were granted from time to time by the Option Committee to
employees, directors, consultants, agents, independent contractors, and others
who contributed to the Company's success. The terms of the options were up to
ten years and were exercisable as determined by the Option Committee, provided
that the option generally did not become exercisable before six months from the
date of grant. The grant prices had to be no less than 50% and 100% of the fair
market value for non-incentive and incentive options, respectively, and were
generally granted at the market close price on the day prior to the grant. The
options accelerated upon a change in control as defined in the 1990 Plan.
Generally, options vested at a rate of 25% per annum on the anniversary date of
grant. The maximum number of shares that were subject to options granted under
the 1990 Plan during any calendar year to any executive officer was 200,000.

     1997 Plan

The 1997 Plan was adopted in February 1997 and will expire in February 2007,
unless earlier terminated by the Board of Directors. Under the 1997 Plan, an
aggregate of 1,312,500 shares are reserved for issuance upon exercise of either
incentive or non-incentive options, which may be granted from time to time by
the Option Committee to employees, directors, consultants, agents, independent
contractors, and others who contribute to the Company's success. The terms of
the options may be up to ten years and are exercisable as determined by the
Option Committee,

                                       16


provided that the option generally does not become exercisable before six months
from the date of grant. The grant prices must be no less than 50% and 100% of
the fair market value for non-incentive and incentive options, respectively, and
are generally granted at the market close price on the day prior to the grant.
The options accelerate upon a change in control as defined in the 1997 Plan. At
March 1, 2001, there were 116,063 options available for grant under the 1997
Plan. Generally, options vest 25 % per annum on the anniversary date of grant.
The maximum number of shares that may be subject to options granted under the
1997 Plan during any calendar year to any executive officer is 200,000. The
Board of Directors is recommending that the stockholders approve an amendment to
the 1997 Plan to increase the number of shares reserved thereunder from
1,312,500 to 2,262,500. For a description of this proposal and for further
information regarding the 1997 Plan, see Proposal 2.


     1998 Plan

The 1998 Plan was adopted in January 1998 and will expire in December 2007,
unless earlier terminated by the Board of Directors. Under the terms of the 1998
Plan, up to an aggregate of (i) 250,000 shares of NCI common stock and (ii)
750,000 shares of Common Stock of the Company were reserved for issuance upon
the exercise of non-incentive options which may be granted from time to time by
the Option Committee of the Board of Directors to employees, directors,
consultants, agents, independent contractors and others who contribute to the
Company's success. The terms of the options may be up to ten years and are
exercisable as determined by the Option Committee. Each grant originally
provided for an exercise price of $5.00 per share of NCI common stock
(approximately $6.68 per share of Common Stock of the Company in the event such
options became exercisable for the Company's Common Stock). As a result of NCI
becoming a wholly owned subsidiary of the Company in May 1999, all outstanding
options converted automatically to options to purchase Common Stock of the
Company. The options accelerate upon a change in control as defined in the 1998
Plan. At March 1, 2001, there were 79,140 options available for grant under the
1998 Plan. Generally, options vest at 25% per annum on the anniversary date of
the grant.

     1995 Director Plan

In August 1995, the Company adopted the 1995 Director Plan authorizing the
issuance of five-year options to purchase an aggregate of 230,000 shares at an
exercise price equal to the fair market value of Common Stock at date of grant.
All of the options were granted to Directors under the 1995 Director Plan and no
further options are available for grant. As of March 1, 2001, all options had
been exercised.

401(k) Plan

Effective as of January 1, 1998, the Company adopted its 401(k) Plan (the
"Plan"), which includes a cash-or-deferred arrangement under Section 401(k) of
the Internal Revenue Code of 1986, as amended. The Plan was established to
provide retirement and other benefits to employees of the Company. Employees
qualify to participate in the Plan on the first of the month following their
date of hire. Participants may designate up to 15% of their compensation

                                       17


to be contributed to the Plan on a pre-tax basis ("Employee Elective
Contributions"). Participants will be 100 % vested in their Employee Elective
Contributions (including earnings) at all times.

The Company matches 50% of the first 6% of an employee's contributions to the
Plan. Participants will generally vest in the Company's contributions (including
earnings) at the rate of 33.3% on the first anniversary from date of
participation, 66.6% on the second anniversary from date of participation and
100% on the third anniversary from date of participation.

Compensation Committee Interlocks and Insider Participation

During the year ended December 31, 2000, the members of the Compensation
Committee, which also acts as the Stock Option Committee, have been Richard L.
Casey and Joseph A. Mollica, Ph.D., neither of whom is an officer or employee or
former officer of the Company or any of its subsidiaries. Mr. Casey and Dr.
Mollica were granted stock options in 2000. See "Director Compensation." No
member of the Compensation Committee has any interlocking relationship with any
other corporation that requires disclosure under this heading.

Compensation Committee Report

The Compensation Committee is responsible for setting the Company's policy with
respect to the compensation of the Company's senior executive officers,
including the Chief Executive Officer, and administering the Company's stock
option plans. The Company's policy is to establish a compensation program that
will attract, retain and motivate qualified members of senior management in a
manner that is competitive with other companies in the biotechnology industry.
The key elements in this policy are salary, stock options, and availability of a
cash bonus. As the Company has only recently emerged from the development stage,
revenues and profits have been largely inapplicable as factors in determining
compensation of the Chief Executive Officer and other executives of the Company.
Rather, the Compensation Committee in the past has looked to qualitative
factors, including the officers' efforts to build the organization, to expand
the Company's potential product line (through acquiring new technologies or
otherwise), to expand the range of applications therefor, and to intensify the
Company's research and development efforts for its potential products.

As noted above, the key elements of an executive's compensation consist of base
salary, a cash bonus and stock options. These items are discussed in more detail
in the following sections of this Report.

     (a) Base Salary

The Company compensates its executive officers partly through salaries. As
described above, based on the factors described therein, the Compensation
Committee reviews certain officers' salaries, including Mr. Dunning's (the Chief
Executive Officer during the fiscal year ended December 31, 2000). In connection
with the Company entering into an amended and restated employment agreement with
Mr. Dunning in April 1999, his base salary was reduced from

                                       18


$250,000 to $200,000 effective July 1, 1999, he agreed to forego a bonus in 1999
relating to 1998, and his options were repriced.

     (b) Bonus

The Company's senior executives and employees are eligible to receive a cash
bonus. Subject to negotiated and targeted contractual bonus provisions contained
in certain executives' employment agreements, the amount of bonuses and their
distribution is discretionary, and the general practice is that such bonuses are
recommended by senior management and reviewed by the Compensation Committee and
the Board of Directors. For fiscal 2000, one of the executive officers named in
the Summary Compensation Table (Mr. McIntosh) received a bonus under an
agreement entered into in connection with his termination of employment. See
"Employment Agreements." Mr. Dunning, the Company's Chief Executive Officer
during the fiscal year ended December 31, 2000, did not receive a bonus.

     (c) Stock Based Compensation

Under the Company's stock option plans which have been approved by the
stockholders, stock based compensation in the form of stock options may be
granted to directors, officers, employees, and consultants of the Company. The
purpose of equity participation is to further align the interests between
executive officers and the stockholders in the Company's growth in real value
over the long term.

Stock options, which are generally exercisable for ten years from the date of
grant, generally have an exercise price equal to (or in some cases in excess of)
the closing market price (NASDAQ/National Market) of the Company's Common Stock
on the date of grant and generally vest over three or four years from the grant
date. This approach is designed to provide an incentive to create stockholder
value over the longer term, since the full benefit of the stock option
compensation package generally cannot be realized unless stock appreciation
occurs over several years.

The Compensation/Stock Option Committee determines the number of options to be
granted based principally upon the recommendation of senior management, whose
recommendation in turn is based on their subjective analysis of individual
performance, responsibility, the executive's other compensation (including prior
grants of options, if any) and the executive's retention value to the Company.
No specific weighting is assigned to these factors.

In 2000, Mr. Dunning was granted options to purchase 50,000 shares of Common
Stock vesting over two years, which options Mr. Dunning relinquished upon his
resignation as Chief Executive Officer effective March 1, 2001. Certain other
executive officers, including four other executive officers named in the Summary
Compensation Table, were granted options in 2000. See "Option Grants in the
Fiscal Year Ended December 31, 2000."

In 1993, Congress enacted the Omnibus Reconciliation Act of 1993 (OBRA) which,
among other things, establishes certain requirements in order for compensation
exceeding $1,000,000 earned by certain senior executives to be deductible.
Although the Company's historical levels

                                       19


of executive compensation have been substantially less than $1,000,000 per
employee annually, the Board of Directors has established certain restrictions
on the granting of options under the Company's stock option plans to assist in
qualifying such compensation for an exemption under OBRA, except that non-
qualified options granted with an exercise price less that the fair market value
of the Common Stock on the date of grant are permitted under such plans and will
not qualify for such exemption. Also, in light of the composition of the
Compensation/Stock Option Committee prior to November 1999, options granted
prior thereto will not qualify for such exemption and there can be no assurance
that such exemption will be available in the future. The Board of Directors does
not believe that other components of the Company's compensation will be likely
to exceed $1,000,000 for any executive officer in the foreseeable future and
therefore concluded that no further action with respect to qualifying such
compensation for deductibility was necessary at this time. The Board will
continue to evaluate the advisability of qualifying the deductibility of such
compensation in the future.

Report of the Audit Committee

The Board of Directors has appointed an Audit Committee composed of three
directors. The Board of Directors believes that each member is "independent" of
the Company and management, as that term is defined in the NASDAQ listing
standards. The Audit Committee operates under a written charter adopted by the
Board of Directors, which is attached hereto as Appendix A.

Management is responsible for the Company's internal controls and the financial
reporting process. The Company's independent accountants, KPMG LLP, are
responsible for performing an independent audit of the Company's financial
statements in accordance with auditing standards generally accepted in the
United States of America and the issuance of a report thereon. The Audit
Committee's responsibility is to monitor and oversee these processes.

In this context, the Audit Committee has met and held discussions with
management and the independent accountants. Management represented to the Audit
Committee that the Company's financial statements were prepared in accordance
with accounting principles generally accepted in the United States of America,
and the Audit Committee has reviewed and discussed the audited financial
statements with management and the independent accountants. The Audit

                                       20


Committee discussed with the independent accountants matters required to be
discussed by Statement on Auditing Standards No. 61, which includes, among other
things:

     a)  methods used to account for significant unusual transactions;

     b)  the effect of significant accounting policies in controversial or
emerging areas for which there is a lack of authoritative guidance or consensus;

     c)  the process used by management in formulating particularly sensitive
accounting estimates and the basis for the auditors' conclusions regarding the
reasonableness of these estimates; and

     d)  disagreements with management over the application of accounting
principles, the basis for management's accounting estimates, and the disclosures
in the financial statements.

The independent accountants also provided to the Audit Committee the written
disclosures required by Independence Standards Board Standard No. 1,
"Independence Discussions with Audit Committees," and the Audit Committee
discussed with the independent accountants that firm's independence from the
Company and its management.

The members of the Audit Committee are not professionally engaged in the
practice of auditing or accounting and are not experts in the fields of
accounting or auditing, including in respect of auditor independence. Members of
the Audit Committee rely without independent verification on the information
provided to them and on the representations made by management and the
independent accountants. Accordingly, the Audit Committee's oversight does not
provide an independent basis to determine that management has maintained
appropriate accounting and financial reporting principles or appropriate
internal control and procedures designed to assure compliance with accounting
standards and applicable laws and regulations. Furthermore, the Audit
Committee's considerations and discussions referred to above do not assure that
the audit of the Company's financial statements has been carried out in
accordance with generally accepted auditing standards, that the financial
statements are presented in accordance with generally accepted accounting
principles or that the Company's auditors are in fact "independent."

Based on the Audit Committee's discussion with management and the independent
accountants and the Audit Committee's review of the representation of management
regarding the audited financial statements and of the report of the independent
accountants to the Audit Committee, and subject to the limitations on the role
and responsibilities of the Audit Committee referred to above and in the
Charter, the Audit Committee recommended to the Board of Directors, and the
Board has approved, that the audited financial statements be included in the
Company's Annual Report on Form 10-K for the fiscal year ended December 31,
2000, for filing with the Securities and Exchange Commission.

Audit Fees

The Company has been billed a total of $100,000 by KPMG LLP, the Company's
independent auditors, for professional services rendered for the audit of the
Company's annual financial statements for the fiscal year ended December 31,
2000 and the limited reviews of interim financial statements included in the
Company's Forms 10-Q filed during the last fiscal year.

Financial Information Systems Design and Implementation Fees

The Company has not been billed any amounts by KPMG LLP for professional
services rendered in connection with financial information systems design and
implementation during the fiscal year ended December 31, 2000.

All Other Fees

The Company has been billed a total of $125,000 for all other services rendered
by KPMG LLP that are not set forth above. These included fees for services
related to proxy preparation, miscellaneous SEC matters and tax compliance and
consultation.

The Audit Committee of the Board of Directors of the Company has considered
whether the provision of financial information systems design and implementation
and other non-audit services is compatible with maintaining KPMG LLP's
independence.

Relationship with Baxter

     Overview

The Company's significant operating activities began with its December 1997
acquisition of the business of the Immunotherapy Division (the "Division") of
the Biotech Business Group of Baxter Healthcare Corporation ("Baxter"). In
connection therewith, the Company entered into several agreements with Baxter by
which Baxter agreed to perform certain activities related to the Division. In
1999, the parties entered into additional agreements to restructure Baxter's
ownership interest in the Company and NCI and to modify their business
arrangements. Pursuant to such agreements, during the year ended December 31,
2000, NCI paid Baxter the aggregate amount of $8,240,342.

     December 1997 - Acquisition of the Immunotherapy Division

In December 1997, the Company acquired substantially all of the assets of the
Division. In exchange for these assets, Baxter received (i) 2,750,000 shares of
Common Stock, (ii) 66,304 shares of the Company's Series A Convertible Preferred
Stock, convertible into Common Stock at a conversion price of $22.00 per share,
(iii) 19.5% of the outstanding common stock of NCI, (iv) a warrant to purchase
an additional 6% of the then outstanding common stock of NCI for an aggregate
$6,000,000, and (v) the right to receive payments up to $21,000,000 from NCI
upon the occurrence of certain milestone events. The $21,000,000 represents the
maximum potential amount that could be paid by the Company when, and if, certain
FDA and European regulatory approvals are obtained. As the amount of the
contingent consideration, if any, was not determinable nor was the achievement
of the milestones considered probable at the date of the acquisition, it was
excluded from the determination of the cost of the acquisition. Depending on the
progress in certain of the Company's therapeutic programs, a payment of up to
$2,000,000 could be required for milestones achieved in 2001. In addition,
Baxter purchased $30,000,000 principal amount of NCI's 6 1/2% convertible
subordinated debentures. Many of these terms have been renegotiated as set forth
below.

Marketing, Sales and Distribution Agreement ("Distribution Agreement"). NCI
- ----------------------------------------------------------------------
appointed Baxter as its exclusive worldwide marketing, sales and distribution
entity for NCI's Isolex(R) and Maxsep(R) products and reagent kits, with the
right of first offer with respect to acquiring such rights for NCI's future
products. NCI agreed to supply to Baxter products and kits at a discount to
NCI's suggested retail price. The Distribution Agreement was, by its terms, to
expire December 17, 2008. However, as described below, as of November 30, 1999,
the parties terminated the agreement.

                                       24


Services Agreement. Baxter agreed to provide the following services as
- ------------------
necessary to meet NCI's requirements: access to Baxter's Information Management
Center; quality and compliance training; access to the Baxter Institute for
Training and Development; and access to specific accounts through Baxter's
General Ledger and Fixed Assets Systems. NCI agreed to pay only for those
services requested. In addition, Baxter agreed to manufacture, warehouse and
manage inventory for certain clinical codes under protocols in accordance with
the terms of the Hardware and Disposables Supply Agreement and the Hardware and
Disposables Manufacturing Agreement and, at its option, to manufacture certain
prototype products for the research market at a cost to NCI of time and
materials plus 20%. Baxter's obligation to provide the services was extended
until June 30, 1999, at which time (as described below) the Services Agreement
was terminated.

Hardware and Disposables Manufacturing Agreement. Baxter agreed to manufacture
- ------------------------------------------------
on a non-exclusive basis for NCI certain Isolex(R) and Maxsep(R) products and
components and to complete assembly of Isolex(R) and Maxsep(R) instruments and
disposable sets. NCI agreed to pay Baxter's Fully Loaded Cost for the products
and components for the first three years, and Baxter's Fully Loaded Cost plus
15% for the remaining years. Baxter's "Fully Loaded Cost" means the cost to
Baxter of manufacturing the items, including any royalties payable by Baxter in
connection with such manufacturing. The Agreement expires on December 17, 2002.

Antibody Manufacturing and Storage Agreement. Baxter agreed to manufacture on a
- --------------------------------------------
non-exclusive basis for NCI certain antibodies, reagents and reagent kits used
in connection with the Isolex(R) and Maxsep(R) products. NCI agreed to pay
Baxter's Fully Loaded Cost for the antibodies, reagents and reagent kits for the
first three years, and Baxter's Fully Loaded Cost plus 15% for the remaining
years. The Agreement expires on December 17, 2002.

Hardware and Disposables Supply Agreement. Baxter agreed to supply to NCI
- -----------------------------------------
certain of Baxter's products and components in conjunction with the manufacture,
use and sale of Isolex(R) and Maxsep(R) products. Baxter granted to NCI the
exclusive worldwide royalty-free right to distribute such products and
components in connection with ex vivo cell processing, subject to certain
exceptions. NCI agreed to pay Baxter's Fully Loaded Cost for the products and
components for the first three years, Baxter's Fully Loaded Cost plus 15% for
the next two years and Baxter's Fully Loaded Cost plus 30% for the remaining
years. The Agreement expires on December 17, 2008.

License Agreements. Pursuant to four separate sublicense agreements, Baxter
- ------------------
sublicensed to NCI its rights under the following licenses: license from Baxter
and Becton, Dickinson & Company to certain CD34+ cell population and related
antibody and method patents (the "First License"); license from Becton,
Dickinson & Company ("Becton Dickinson") to certain B cell antibodies; license
from Chiron Therapeutics to certain breast cancer antibodies; and license from
Professor Bernd Dorken to certain B cell antibodies. In addition, pursuant to a
royalty assignment and agreement, Baxter assigned to NCI its rights to receive
royalties under three sublicenses Baxter had previously granted under the First
License.

                                       25


Non-Competition and Confidentiality Agreement.  Each party agreed not to,
- ---------------------------------------------
directly or indirectly, engage in, render advisory services to an entity that
engages in, or be a joint venturer, partner, licensor or shareholder of more
than 2% of any entity that engages in, the marketing, sale or distribution of
any product that directly competes with certain products of the other. In the
case of Baxter's products, such protected products are for use in on-line
separation of human blood into its constituents. In the case of the Company's
and NCI's products, such protected products are for use in ex vivo cell
selection or genetic alteration and/or expansion in combination with such
selection. Baxter's non-competition obligations expire on the later of December
17, 2004, one year after the date on which Baxter does not own 10% of NCI's
common stock nor has a seat on NCI's board of directors, or the termination of
the Distribution Agreement. The Company's obligations expire on the later of
December 17, 2004, or one year after the date on which the Company does not have
voting control of NCI nor has a seat on NCI's board of directors. NCI's
obligations expire on the later of December 17, 2010, or the termination of the
Hardware and Disposables Supply Agreement.

The Company and Baxter are also parties to a Registration Rights Agreement dated
December 17, 1997 whereby the Company has granted certain demand and piggyback
rights to Baxter.

The Company, certain current and former directors of the Company, certain other
parties and Baxter are also parties to a Voting Agreement. For a description of
the Voting Agreement see "Proposal 1-Election of Directors."

      January 1999 through June 1999 - Transfers of Ownership and Assets

In early 1999, the Company and Baxter agreed that it would be in the best
interests of both parties to (i) restructure Baxter's ownership interests in the
Company and NCI, and (ii) modify certain business arrangements among the
Company, NCI and Baxter. In January 1999, the Company and Baxter agreed that the
Company would purchase Baxter's interest in NCI (other than Baxter's right to
milestone payments), resulting in the Company owning 100% of NCI. In exchange
for the common stock, warrant and convertible debentures of NCI then held by
Baxter, Baxter received (i) 750,000 shares of Common Stock, (ii) a warrant to
purchase an additional 1,300,000 shares of Common Stock at an exercise price of
$4.60 per share, (iii) a change in the conversion price of the 70,282 shares of
Series A Convertible Preferred Stock then held by Baxter (an increase from
66,304 shares resulting from dividends payable in kind) from $22.00 to $11.00
per share, and (iv) approximately $33,000,000 principal amount of the Company's
6 1/2% convertible subordinated debentures (replacing the $30,000,000 principal
amount of NCI's 6 1/2% convertible subordinated debentures, plus accrued
interest).

Following the closing on May 28, 1999 (which occurred after stockholder approval
of the transaction at the Company's May 25, 1999 annual meeting of
stockholders), NCI became a wholly owned subsidiary of the Company.

In June 1999, the Company and Baxter entered into a series of agreements dated
June 30, 1999 pursuant to which, among other things, Baxter transferred the
sales, marketing and distribution responsibilities for Isolex(R) and the
Company's other cell therapy products to the Company. Pursuant to an asset
transfer agreement, the Company agreed to purchase from Baxter the

                                       26


finished goods inventory, copies of customer lists and accounting books and
records, hardware and related assets leased or owned, and agreements with
customers and service contracts, all relating to the products previously
marketed and distributed by Baxter under the Distribution Agreement. In
addition, certain Baxter personnel transferred to the Company and became part of
the Company's worldwide sales force. The purchase price for the transferred
assets was equal to the price Baxter as a distributor had originally paid to NCI
for the finished goods inventory plus the book value of all other transferred
assets. The closing for the transfer of assets in the United States and Canada
occurred on June 30, 1999 and in the rest of the world occurred on November 30,
1999. For the year ended December 31, 1999, the Company's cost of repurchasing
the inventory in the United States was approximately $1,000,000 and in the rest
of the world was approximately $2,000,000. Additionally, the Company purchased
approximately $1,200,000 in devices classified as fixed assets. For the year
ended December 31, 2000, there were no repurchases of inventory or devices.

In connection with the asset transfer, the Company and Baxter also entered into
a royalty agreement pursuant to which Baxter will receive a royalty of 5% on the
Company's net sales of Isolex(R) and related cell therapy products from January
1, 2001 until December 17, 2008. (Baxter was also entitled to a royalty of 5% on
the Company's net sales of the foregoing products in excess of $50,000,000 in
the year 2000, which did not occur). In addition, Baxter extended a $20,000,000
line of credit to the Company pursuant to a credit agreement, which agreement
terminated by its terms without being drawn on, upon the closing of the November
1999 financing described below.

As of June 30, 1999 and November 30, 1999, respectively, the Services Agreement
and Distribution Agreement were terminated. The Company now has direct control
of sales of its Isolex(R) and cell therapy products through its field sales
group in the United States and its European headquarters in Belgium. For regions
outside the United States, Canada and Western Europe, NCI and its European
subsidiary are entering into arrangements with third party distributors for
distribution of the Isolex(R) and cell therapy products. The Company is entering
into distribution agreements with distributors unrelated to Baxter in portions
of Northern and Southern Europe and East Asia. In addition, NCI's European
subsidiary has executed an agreement with a Baxter subsidiary for distribution
in Eastern Europe, portions of North Africa and the Middle East. NCI and its
European subsidiary have also entered into several interim services agreements
with Baxter pursuant to which Baxter will continue to provide services in Europe
and certain other regions relating to warehouse and shipping, information
systems, general infrastructure and administrative support, quality assurance
and regulatory affairs.

Baxter has also agreed to continue to provide worldwide services relating to the
installation, repair and maintenance of NCI's cell therapy products pursuant to
the terms of several instrument services agreements dated June 30, 1999 and
November 30, 1999 covering various regions of the world where such products are
sold.  Pursuant to the agreements, NCI (or its European affiliate, Nexell
International sprl) will provide training to Baxter personnel, and such
personnel will provide the services as requested by NCI or its customers.  NCI
will pay for the services an amount equal to Baxter's Fully Loaded Cost, plus
15% in the case of the United States, Canada and Europe, and plus 20% in the
rest of the world.  The instrument services agreements expire upon termination
of the Manufacturing Agreement.

                                       27


Notwithstanding the termination of the Distribution Agreement, the parties have
agreed that Baxter's obligations with respect to the delivery of Isolex(R) and
other cell therapy products under the Manufacturing Agreement, Antibody
Agreement and Supply Agreement shall remain in full force and effect.

The assets purchased from Baxter in conjunction with the termination of the
supply and manufacturing agreements were accounted for as an asset purchase for
cash. The types of items purchased include saleable inventory, Isolex(R) devices
that are located in customer sites both in the United States and in Europe and
minor amounts of promotional materials.

     November 1999 - Private Placement Financing

On November 24, 1999, the Company closed a private placement of its securities
to certain institutional investors pursuant to the terms of a securities
agreement (the "Securities Agreement"). The private placement consisted of the
issuance of (i) 63,000 shares of the Company's newly designated Series B
Cumulative Convertible Preferred Stock ("Series B Preferred Stock"), convertible
at the option of the holder at any time until November 24, 2006 (at which time
the conversion is automatic) into shares of Common Stock at $11.00 per share,
subject to anti-dilution adjustment in certain circumstances; (ii) one right per
share of Series B Preferred Stock to put such share to Baxter International Inc.
("Baxter International"), an affiliate of Baxter, from November 24, 2002 until
November 24, 2004 unless earlier terminated (the "Put Rights"); (iii) warrants
to purchase up to 750,000 shares of Common Stock at a purchase price of $12.00
per share, subject to anti-dilution adjustment in certain circumstances,
exercisable for five years; and (iv) a class of performance warrants to purchase
shares of Common Stock at a purchase price of $.04 per share, subject to anti-
dilution adjustment in certain circumstances, exercisable after five years. The
number of performance warrants that may be exercised adjust based upon the
closing price of the Common Stock at the date of exercise, ranging from zero (if
the closing price exceeds $20.00 per share) to 1,500,000 shares (if the closing
price is equal to or less than $12.00 per share). Net proceeds to the Company
from the private placement were approximately $60,400,000. The Company used a
portion of the proceeds in November 1999 to retire approximately $33,900,000 of
the Company's convertible debentures held by Baxter, and intends to use the
remainder of the proceeds for general corporate purposes.

On November 24, 1999, the Company and Baxter International entered into an
agreement (the "Side Letter Agreement") to provide that the conversion price for
the Series B Preferred Stock purchased by Baxter International in the event the
Put Rights are exercised (the "Put Series B Preferred Stock") would be adjusted
on November 24, 2004 (or earlier, if 100% of the Series B Preferred Stock is put
to Baxter International) but only in the event that an amount in excess of
$15,000,000 is purchased by Baxter International, as follows: (i) for the Put
Series B Preferred Stock in an amount up to $53,000,000 (computed on the basis
of the liquidation preference for such stock) (the "Threshold"), the conversion
price would be adjusted to equal the closing price of the Common Stock on the
respective date or dates such Series B Preferred Stock was purchased by Baxter
International (including purchases below the $15,000,000 amount), less a 5%
discount (subject to a floor price equal to the closing price of the Common
Stock on November 24, 1999, unless shareholder approval is obtained if required
by the rules of the

                                       28


Nasdaq Stock Market); (ii) for the Put Series B Preferred Stock in an amount in
excess of the Threshold, then the conversion price would be adjusted to equal
the closing price of the Common Stock on November 24, 1999. The dollar amount of
the Put Series B Preferred Stock would be deemed to accrue interest (payable in
kind in shares of Series B Preferred Stock) from the respective date or dates
the Series B Preferred Stock is put to Baxter International to the date the
adjusted conversion price is determined, at a rate equal to the applicable
three-year U.S. Treasury Note rate at the date of each such purchase, plus 100
basis points. In the event that the foregoing conversion adjustments would not
be permissible under Delaware law, the Company has agreed to take such action as
is appropriate to exchange the Put Series B Preferred Stock for an equal number
of shares of a new series of preferred stock of the Company, having the
identical terms, conditions, preferences and rights of the Series B Preferred
Stock, except that it would bear the conversion price adjustment described
above.

The Company and Baxter International also entered into a Put Agreement dated
November 24, 1999 pursuant to which the parties made certain representations to
each other, and agreed to take certain actions in connection with, and to
provide for certain rights and remedies regarding the transactions contemplated
by, the Securities Agreement.

     Other Transactions

On December 17, 1999 and 2000, respectively, pursuant to the terms of the Series
A Preferred Stock owned by Baxter, the Company issued 4,216 additional shares of
Series A Preferred Stock and 4,469 additional shares of Series A Preferred
Stock, respectively, to Baxter as a result of dividends payable in kind.

On December 21, 2000, the Company entered into a sale-leaseback agreement under
which the Company sold certain fixed assets to Baxter that were subsequently
leased back to the Company over a three-year term.


            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires that the Company's
executive officers, directors and holders of more than 10% of the Common Stock
(collectively, "Reporting Persons") file reports of their holdings and
transactions in the Common Stock with the Securities and Exchange Commission.
Based on a review of Section 16 forms filed by the Reporting Persons during the
last fiscal year and written representations of the Reporting Persons, the
Company believes that the Reporting Persons timely complied with all applicable
Section 16 filing requirements, except that Michel Bergh, Ph.D. and Lewis
Chapman filed late their initial ownership reports on Form 3, William A.
Albright, Jr., David Hirsch, Jeanne Pierson and Amy Ross filed late their
amended initial ownership reports on Form 3, Michael Griffith, Ph.D. filed late
one report on Form 4 relating to two transactions involving a purchase of Common
Stock, Dennis Van Epps, Ph.D., filed late one report on Form 4 relating to one

                                  PROPOSAL 2

APPROVAL OF AN INCREASE IN THE NUMBER OF SHARES OF COMMON STOCK ISSUABLE UNDER
                          THE 1997 STOCK OPTION PLAN


General

Under the Company's 1997 Incentive and Non-Incentive Stock Option Plan, as
amended, approved by stockholders in 1997, an aggregate of 1,312,500 shares are
reserved for issuance upon exercise of options thereunder. A copy of the 1997
Plan is attached as Appendix B. The 1997 Plan originally authorized 250,000
shares for issuance. In 1998, the Board of Directors and stockholders approved
an amendment to the 1997 Plan increasing the number of shares reserved for
issuance to 500,000, in 1999, the Board of Directors and stockholders approved
an amendment increasing the number of shares reserved for issuance to 750,000,
and in 2000, the Board of Directors and stockholders approved an amendment
increasing the number of shares reserved for issuance to 1,312,500. Under the
1997 Plan, incentive stock options, as defined in section 422 of the Internal
Revenue Code (the "Code"), may be granted to employees and non-incentive stock
options may be granted to employees, directors and other persons as the Stock
Option Committee appointed by the Board of Directors determines will contribute
to the Company's success, at exercise prices equal to at least 100% (with
respect to incentive stock options) and at least 50% (with respect to non-
incentive stock options) of the fair market value of the Common Stock on the
date of grant. In addition to selecting the optionees, the Committee determines
the number of shares of Common Stock subject to each option, the term of each
non-incentive stock option, the time or times when the non-incentive stock
option becomes exercisable, and otherwise administers the 1997 Plan. Options are
granted for a term determined by the Committee, not to exceed ten years, and are
exercisable on terms and conditions determined by the Committee. Generally,
options granted under the 1997 Plan may not be exercised more than three months
following termination of employment or engagement, except terminations by reason
of death or disability, in which case such options may be exercised for one year
following such event. However, the Committee may in its discretion extend the
time required to exercise non-incentive options for up to ten years after the
date of grant. Options become immediately exercisable upon a change in control
as defined in the 1997 Plan. The 1997 Plan will terminate in February 2007
unless earlier terminated by the Board of Directors.

The purpose of the 1997 Plan is to further the growth and development of the
Company by encouraging selected employees, directors and other persons who
contribute and are expected to contribute materially to the Company's success to
obtain a proprietary interest in the Company through the ownership of its Common
Stock, thereby providing such persons with an added incentive to promote the
best interests of the Company and affording the Company a means of attracting
persons of outstanding ability to its service. Approximately 100 employees of
the Company and an indeterminate number of consultants and others are eligible
to participate in the 1997 Plan.

As of the March 1, 2001, options to purchase an aggregate of 1,083,374 shares of
Common Stock had been granted and were outstanding under the 1997 Plan, options
for 13,063 shares had

                                       31


been exercised, 116,063 shares were available for future grants thereunder and
79,140 shares were available for future grants under other plans.

The Board of Directors has proposed that the total number of shares of Common
Stock which may be issued upon the exercise of options granted under the 1997
Plan be increased by 950,000, from 1,312,500 to 2,262,500, to ensure additional
options are available in the future to compensate and motivate existing
participants and employees and to attract employees in the future. Pursuant to
the terms of the 1997 Plan the foregoing proposed increase must be approved by
the stockholders of the Company. In all other respects, the terms of the 1997
Plan will remain unchanged.

Plan Benefits

During the fiscal year ended December 31, 2000, stock options to purchase shares
of Common Stock were granted to the Company's named executive officers, as set
forth in the table captioned "Option Grants in the Fiscal Year Ended December
31, 2000" above. Stock options were granted during the year to all executive
officers of the Company as a group to purchase 449,250 shares of Common Stock at
an average weighted exercise price of $17.63 per share. In addition, stock
options were granted to all other employees of the Company as a group to
purchase 374,493 shares of Common Stock at an average weighted exercise price of
$16.06 per share. The number of options to be granted in the future to the
Company's executive officers and to other employees is not determinable at this
time.

On April 23, 2001, the closing sale price of the Common Stock on The Nasdaq
Stock Market was $1.67 per share.

Federal Income Tax Consequences

The following is based upon federal tax laws and regulations as presently in
effect and does not purport to be a complete description of the federal income
tax aspects of the 1997 Plan. Also, the specific state tax consequences to each
participant under the 1997 Plan may vary, depending upon the laws of the various
states and the individual circumstances of each participant. Accordingly,
participants should consult with their own tax advisors.

     Incentive Stock Options

No taxable income is recognized by the optionee upon the grant of an incentive
stock option. Further, no taxable income will be recognized by the optionee upon
exercise of an incentive stock option and no expense deduction will be available
to the Company, provided the optionee holds the shares acquired upon such
exercise for at least two years from the date of grant of the option and for at
least one year from the date of exercise. Any gain on the subsequent sale of the
shares will be considered long-term capital gain provided the two-year and one-
year holding periods are met. The gain recognized upon the sale is equal to the
excess of the amount realized upon the sale (usually the selling price of the
shares) over the exercise price. Therefore, the net federal income tax effect on
an optionee fulfilling the foregoing holding requirements is to defer, until the
shares are sold, taxation of any increase in the value of the shares from the
exercise price

                                       32


and to treat such gain, at the time of sale, as capital gain rather than
ordinary income. However, in general, if the optionee sells the shares within
two years from the date of the option grant or within one year from the date of
exercise (referred to as a "disqualifying disposition"), the optionee will
recognize taxable income at ordinary tax rates in an amount equal to the lesser
of (i) the value of the shares on the date of exercise, less the exercise price;
or (ii) the amount realized on the date of sale, less the exercise price, and
the Company will receive a corresponding business expense deduction. The balance
of any gain recognized on a disqualifying disposition will be long-term or
short-term capital gain depending upon the holding period of the optioned
shares. The special two-year and one-year holding periods for incentive options
do not apply to option shares which are disposed of by the optionee's estate or
a person who acquired such shares by reason of the death of the optionee.

An employee may be subject to the alternative minimum tax upon exercise of an
incentive stock option since the excess of the fair market value of the shares
purchased at the date of exercise over the exercise price must be included in
alternative minimum taxable income, unless the shares are disposed of in the
same year that the option was exercised.

     Non-Incentive Stock Options

As in the case of incentive stock options, the grant of a non-incentive stock
option will not result in any taxable income to the optionee. However, the tax
treatment upon exercise of non-incentive stock options is different. Generally,
the optionee will recognize ordinary income when the option is exercised in the
amount by which the fair market value of the shares acquired upon exercise of
the option on the date of exercise exceed the exercise price and the Company
will be entitled to a corresponding business expense deduction. The income
recognized by the optionee is compensation income subject to income tax
withholding by the Company. The Company will generally be entitled to an income
tax deduction for the amount of the "spread" at the time a non-incentive option
is exercised, provided that it complies with applicable reporting and
withholding requirements.

The fair market value of the shares on the date of exercise will constitute the
tax basis of the shares for computing gain or loss on any subsequent sale. Any
gain or loss recognized by the optionee upon the subsequent disposition of the
shares will be treated as capital gain or loss and will qualify as long-term
capital gain or loss if the shares have been held for the requisite holding
period (more than twelve months at the date of this Proxy Statement).

     Section 162(m) of the Code

Under Section 162(m) of the Code, certain compensation payments in excess of $1
million are subject to a limitation on deductibility for the Company. The
limitation on deductibility applies with respect to that portion of a
compensation payment for a taxable year in excess of $1 million to either the
Company's Chief Executive Officer or any one of its four other most highly
compensated executive officers. Certain performance-based compensation is not
subject to the limitation on deductibility. Options can qualify for this
performance-based exception, but only if they are granted at fair market value
by a committee comprised solely of "outside directors," the total number of
shares that can be granted to an executive for a specified period is stated, and

                                       33


shareholder and Board approval of the plan is obtained. The Board of Directors
has established certain restrictions on the granting of options under the 1997
Plan to assist in qualifying such compensation for an exemption except that non-
qualified options granted with an exercise price less than the fair market value
of the Common Stock on the date of grant are permitted under the 1997 Plan and
will not qualify for such exemption. Also, in light of the composition of the
Compensation/Stock Option Committee prior to November 1999, options granted
prior thereto will not qualify for such exemption and there can be no assurance
that such exemption will be available in the future.

Required Vote

Approval of the amendment to the 1997 Plan requires the affirmative vote by the
holders of a majority of the outstanding shares of Common Stock present in
person or represented by proxy at the Annual Meeting and entitled to vote.

                                  APPENDIX B

                       1997 INCENTIVE AND NON-INCENTIVE

                               STOCK OPTION PLAN
                                      OF
                            NEXELL THEAPEUTICS INC.
                  (FORMERLY NAMED VIMRx PHARMACEUTICALS INC.)


     1.   Purpose of Plan.

          The purpose of this Incentive and Non-Incentive Stock Option Plan
("Plan") is to further the growth and development of VIMRx Pharmaceuticals Inc.
("Company") and any subsidiaries thereof by encouraging selected employees,
directors and other persons who contribute and are expected to contribute
materially to the Company's success to obtain a proprietary interest in the
Company through the ownership of stock, thereby providing such persons with an
added incentive to promote the best interests of the Company and affording the
Company a means of attracting to its service persons of outstanding ability.

     2.   Stock Subject to the Plan.

          An aggregate of 1,312,500/1/ shares of the Company's Common Stock,
$.001 par value ("Common Stock") subject, however, to adjustment or change
pursuant to paragraph 12 hereof, shall be reserved for issuance upon the
exercise of options which may be granted from time to time in accordance with
the Plan ("Options"). Such shares may be, in whole or in part, as the committee
appointed by the Board of Directors to administer the Plan (hereinafter, the
"Committee") shall from time to time determine, authorized but unissued shares
or issued shares which have been reacquired by the Company. If, for any reason,
an Option shall lapse, expire or terminate without having been exercised in
full, the unpurchased shares covered thereby shall again be available for
purposes of the Plan.

     3.   Administration.

          (a)  Except as provided in paragraph (c) below, the Plan shall be
administered by the Committee. The Board of Directors shall appoint the
Committee from among its members. Such Committee shall be composed of two or
more Directors who, to the extent practicable, shall be "outside directors" as
defined in regulations under Section 162(m) of the Internal Revenue Code of
1986, as amended (the "Code"), and "non-employee directors" as defined by
Regulation 240.16b-3 under the Securities Exchange Act of 1934, as amended. Such
Committee shall have and may exercise any and all of the powers relating to the
administration of the Plan and the grant of Options thereunder as are set forth
in subparagraph 3(b) hereof as the Board of Directors shall confer and delegate.
The Board of Directors shall have power at any time to fill vacancies in, to
change the membership of, or to discharge such Committee. The Committee shall
select one of its members as its chairman and shall hold its meetings at such

___________________________
/1/ The Board of Directors has recommended that this be increased to 2,262,500.
    See Proposal 2.

                                      B-1


time and at such places as it shall deem advisable. A majority of such Committee
shall constitute a quorum and such majority shall determine its action. Any
action may be taken without a meeting by written consent of all the members of
the Committee. The Committee shall keep minutes of its proceedings and shall
report the same to the Board of Directors at the meeting next succeeding.

          (b)  The Committee shall administer the Plan and, subject to the
provisions of the Plan, shall have sole authority in its discretion to determine
the persons to whom, and the time or times at which, Options shall be granted;
the number of shares to be subject to each such Option; the provisions regarding
exercisability of each Option; the expiration date of each Option; whether the
Option shall contain a "cashless exercise" provision; whether all or any portion
of the Options shall be incentive stock options ("Incentive Options") qualifying
under Section 422A of the Code or stock options which do not so qualify ("Non-
Incentive Options"); whether a Non-Incentive Option shall have limited
transferability as permitted under the Plan; and whether a Non-Incentive Option
granted to a non-employee shall terminate following the non-employee's
termination of engagement in performing services for the Company or its
subsidiaries pursuant to Section 9 of the Plan. Both Incentive Options and Non-
Incentive Options may be granted to the same person at the same time provided
each type of Option is clearly designated. In making such determinations, the
Committee may take into account the nature of the services rendered by such
persons, their present and potential contribution to the Company's success and
such other factors as the Committee in its sole discretion may deem relevant.
Subject to the express provisions of the Plan, the Committee shall also have
authority to interpret the Plan; to prescribe, amend and rescind rules and
regulations relating thereto; to determine the terms and provisions of the
respective Option Agreements, which shall be substantially in the forms attached
hereto as Exhibit A and Exhibit B; to amend the provisions of outstanding
Options to provide for accelerated exercisability or the extension of the
expiration date of such Options; and to make all other determinations necessary
or advisable for the administration of the Plan, all of which determinations
shall be conclusive and not subject to review.

          (c)  The Board of Directors may administer the Plan, in lieu of and
with the same powers as the Committee, with respect to any Options granted or to
be granted under the Plan, provided that such administration is consistent with
the provisions of Section 162(m) of the Code.

     4.   Eligibility for Receipt of Options.

          (a)  Incentive Options. Incentive Options may be granted only to
employees (including officers) of the Company and/or any of its subsidiaries. A
director of the Company or any subsidiary who is not an employee of the Company
or of one of its subsidiaries is not eligible to receive Incentive Options under
the Plan. Further, Incentive Options may not be granted to any person who, at
the time the Incentive Option is granted, owns (or is considered as owning
within the meaning of Section 425(d) of the Code) stock possessing more than 10%
of the total combined voting power of all classes of stock of the Company or any
subsidiary (10% Owner), unless at the time the Incentive Option is granted to
the 10% Owner, the option price is at least 110% of the fair market value of the
Common Stock subject thereto and such Incentive

                                      B-2


Option by its terms is not exercisable subsequent to five years from the date of
grant. The aggregate fair market value (determined as of the time an Incentive
Option is granted) of the shares of the Company's Common Stock initially
purchasable upon exercise of an Incentive Option during any calendar year may
not exceed $100,000.

          (b)  Non-Incentive Options. Non-Incentive Options may be granted to
any employees (including employees who have been granted Incentive Options),
directors, consultants, agents, independent contractors and other persons whom
the Board of Directors (or Committee) determines will contribute to the
Company's success.

          (c)  The maximum number of shares that may be subject to options under
this Plan granted during any calendar year to any executive officer of the
Company is 200,000 shares.

          (d)  In the event an outstanding Incentive Option or a portion thereof
no longer qualifies as an incentive stock option under Section 422A of the Code,
such Option or portion thereof, as applicable, thereafter shall be deemed a Non-
Incentive Option under the Plan.

     5.   Option Price.

          The purchase price of the shares of Common Stock under each Option
shall be determined by the Committee, which determination shall be conclusive
and not subject to review, but in no event shall the purchase price be less than
100% of the fair market value of the Common Stock on the date of grant in the
case of Incentive Options (110% of fair market value in the case of Incentive
Options granted to a 10% Owner) and 50% of the fair market value of the Common
Stock on the date of the grant in the case of Non-Incentive Options.

          For purposes of the Plan, unless the Committee determines otherwise,
the fair market value" of a share of Common Stock as of a certain date shall be
the closing sale price of the Common Stock on The Nasdaq Stock Market or, if the
Common Stock is not then traded on The Nasdaq Stock Market, such national
securities exchange on which the Common Stock is then traded, on the trading
date immediately preceding the date the fair market value is being determined.
The Committee may make such other determination of fair market value, based on
other factors, as it shall deem appropriate.

          For purposes of the Plan, the date of grant of an Option shall be the
date on which the Committee shall by resolution duly authorize such Option.

     6.   Term of Options.

          The term of each Option shall be such number of years as the Committee
shall determine, subject to earlier termination as herein provided, but in no
event more than ten years from the date the Option is granted.

     7.   Exercise of Options.

                                      B-3


          (a)  Each Option shall be exercisable to the extent determined by the
Committee, but in no event shall an Option be exercisable until at least six
months from the date of grant, except as otherwise provided in Paragraph 13
herein.

          (b)  An Option may not be exercised for fractional shares of the
Company's Common Stock.

          (c)  Except as provided in paragraphs 9, 10 and 11 hereof, and unless
determined otherwise by the Committee with respect to Non-Incentive Options
granted to non-employees, no Option shall be exercisable unless the holder
thereof shall have been an employee, director, consultant, agent, independent
contractor or other person employed by or engaged in performing services for the
Company and/or a subsidiary continuously from the date of grant to the date of
exercise.

          (d)  The exercise of an Option shall be contingent upon receipt from
the holder thereof of a written representation that at the time of such exercise
it is the optionee's then present intention to acquire the Option shares for
investment and not with a view to the distribution or resale thereof (unless a
Registration Statement covering the shares purchasable upon exercise of the
Options shall have been declared effective by the Securities and Exchange
Commission) and upon receipt by the Company of cash, or a check to its order,
for the full purchase price of such shares. The Committee may, in its
discretion, include a "cashless exercise" provision in the applicable Option
Agreement, in which event the optionee will be permitted (i) to deliver
previously owned shares of Common Stock with a fair market value equal to the
exercise price in payment of the full purchase price of such shares, or (ii) to
request that the Company withhold shares of Common Stock issuable upon exercise
of such Option with a fair market value equal to the exercise price of the
shares being purchased under the Option (thereby reducing the number of shares
issuable upon exercise of the Option).

          (e)  The holder of an Option shall have none of the rights of a
stockholder with respect to the shares purchasable upon exercise of the Option
until a certificate for such shares shall have been issued to the holder upon
due exercise of the Option.

          (f)  The proceeds received by the Company upon exercise of an Option
shall be added to the Company's working capital and be available for general
corporate purposes.

     8.   Transferability of Options.

          No Option granted pursuant to the Plan shall be transferable otherwise
than by will or the laws of descent or distribution and an Option may be
exercised during the lifetime of the holder only by such holder, provided,
however, that the Committee may provide for transferability of a Non-Incentive
Option to an optionee's family members or family trusts.

     9.   Termination of Employment or Engagement.

          (a)  Except as provided in paragraph (b) below, in the event the
employment of the holder of an Option shall be terminated by the Company or a
subsidiary for any reason

                                      B-4


other than by reason of death or disability, or the engagement of a non-employee
holder of a Non-Incentive Option shall be terminated by the Company or a
subsidiary for any reason, such holder may, within three months from the date of
such termination, exercise such Option to the extent such Option was exercisable
by such holder at the date of such termination. Notwithstanding the foregoing,
no Option may be exercised subsequent to the date of its expiration. Absence on
leave approved by the employer corporation shall not be considered an
interruption of employment for any purpose under the Plan. In addition, at the
discretion of the Committee, the exercisability of an outstanding Non-Incentive
Option may be extended to a date determined by the Committee but not beyond ten
years from the date of grant.

          (b)  The Committee may, in its discretion, at the time of grant or by
amending the applicable outstanding Non-Incentive Option, delete the foregoing
termination provision with respect to a Non-Incentive Option granted to a non-
employee of the Company or its subsidiaries.

          (c)  Nothing in the Plan or in any Option Agreement granted hereunder
shall confer upon any Optionholder any right to continue in the employ of the
Company or any subsidiary or obligate the Company or any subsidiary to continue
the engagement of any Optionholder or interfere in any way with the right of the
Company or any such subsidiary to terminate such Optionholder's employment or
engagement at any time.

     10.  Disability of Holder of Option.

          If the employment of the holder of an Option shall be terminated by
reason of such holder's disability, such holder may, within twelve months from
the date of such termination, exercise such option to the extent such Option was
exercisable by such holder at the date of such termination. Notwithstanding the
foregoing, no Option may be exercised subsequent to the date of its expiration.

     11.  Death of Holder of Option.

          If the holder of any Option shall die while in the employ of, or while
performing services for, the Company or one or more of its subsidiaries (or
within six months following termination of employment due to disability), the
Option theretofore granted to such person may be exercised, but only to the
extent such Option was exercisable by the holder at the date of death (or, with
respect to employees, the date of termination of employment due to disability)
by the legatee or legatees of such person under such person's Last Will, or by
such person's personal representative or distributees, within twelve months from
the date of death but in no event subsequent to the expiration date of the
Option.

     12.  Adjustments Upon Changes in Capitalization.

          If at any time after the date of grant of an Option, the Company shall
by stock dividend, split-up, combination, reclassification or exchange, or
through merger or consolidation or otherwise, change its shares of Common Stock
into a different number or kind or class of shares or other securities or
property, then the number of shares covered by such Option and the price per
share thereof shall be proportionately adjusted for any such change by the
Committee

                                      B-5


whose determination thereon shall be conclusive.

          13.  Acceleration of Exercisability Upon Change in Control.

               Upon the occurrence of a "change in control" of the Company (as
defined below), all outstanding Options shall become immediately fully
exercisable. For purposes of the Plan, a "change in control" of the Company
shall mean (i) the acquisition at any time by a "person" or "group" (as such
terms are used Sections 13(d) and 14(d)(2) of the Exchange Act of beneficial
ownership (as defined in Rule 13d-3 under the Exchange Act), directly or
indirectly, of securities representing 50% or more of the combined voting power
in the election of directors of the then outstanding securities of the Company
or any successor or the Company; (ii) the termination of service of directors,
for any reason other than death, disability or retirement from the Board of
Directors, during any period of two consecutive years or less, of individuals
who at the beginning of such period constituted a majority of the Board of
Directors, unless the election of or nomination for election of each new
director during such period was approved by a vote of at least two-thirds of the
directors still in office who were directors at the beginning of the period;
(iii) approval by the stockholders of the Company of any merger, consolidation,
or statutory share exchange as a result of which the Common Stock shall be
changed, converted or exchanged (other than a merger, consolidation or share
exchange with a wholly-owned Subsidiary) or liquidation of the Company or any
sale or disposition of 80% or more of the assets or earning power or the
Company; or (iv) approval by the stockholders of the Company of any merger,
consolidation, or statutory share exchange to which the Company is a party as a
result of which the persons who were stockholders immediately prior to the
effective date of the merger, consolidation or share exchange shall have
beneficial ownership of less than 50% of the combined voting power in the
election of directors of the surviving corporation; provided, however, that no
change in control shall be deemed to have occurred if, prior to such time as a
change in control would otherwise be deemed to have occurred, the Company's
Board of Directors deems otherwise.

          14.  Vesting of Rights Under Options.

               Neither anything contained in the Plan nor in any resolution
adopted or to be adopted by the Committee, the Board of Directors or the
stockholders of the Company shall constitute the vesting of any rights under any
Option. The vesting of such rights shall take place only when a written Option
Agreement, substantially in the form of the Incentive Stock Option Agreement
attached hereto as Exhibit A or the Non-Incentive Stock Option Agreement
attached hereto as Exhibit B, shall be duly executed and delivered by and on
behalf of the Company and the person to whom the Option shall be granted.

          15.  Withholding Taxes.

               Whenever under the Plan shares are to be issued in satisfaction
of the exercise of Options granted thereunder, the Company shall have the right
to require the recipient to remit to the Company an amount sufficient to satisfy
federal, state and local withholding tax requirements prior to the delivery of
any certificate or certificates for such shares.

                                      B-6


     16.    Termination and Amendment.

            The Plan, which was adopted by the Board of Directors on February 6,
1997 and is subject to stockholder approval, shall terminate on February 6, 2007
and no Option shall be granted under the Plan after such date. The Board of
Directors may at any time prior to such date terminate the Plan or make such
modifications or amendments thereto as it shall deem advisable, provided,
however, that shareholder approval shall be required:

     (i)    to increase the number of shares reserved for issuance under the
            Plan;

     (ii)   materially increase the benefits accruing to participants under the
            Plan;

     (iii)  materially modify the requirements of eligibility for participation
            in the Plan; or

     (iv)   if otherwise required to comply with the incentive stock option
            provisions of Section 162(m) of the Code or the listed company
            requirements of The Nasdaq Stock Market or of a national securities
            exchange on which the Common Stock is then traded,

and, provided, further, that no modification or amendment shall adversely affect
the rights of a holder of an Option previously granted under the Plan without
such holder's written consent.

                                      B-7
