Exhibit 10.1

Nabi Biopharmaceuticals

5800 Park of Commerce Boulevard, N.W.

Boca Raton, Florida 33487

Employment Agreement

Effective as of February 15, 2007

Les Hudson, Ph.D

1028 Princeton Kingston Road

Princeton, NJ 08540

Dear Dr. Hudson:

You have agreed to serve on an interim basis as President and Chief Executive
Officer of Nabi Biopharmaceuticals (“Nabi”). This Agreement sets forth the terms
of such employment. This Agreement is effective February 15, 2007 (the
“Effective Date”), when the Nabi Board of Directors elected you as Nabi’s
interim President and Chief Executive Officer.

1. TERM: You will serve as Nabi’s President and Chief Executive Officer for a
period beginning on the Effective Date and ending on August 15, 2007 (the
“Expiration Date”), unless your employment is sooner terminated as provided
below (the “Employment Period”). If you and Nabi agree in writing that your
employment by the Company shall continue beyond the Employment Period, the terms
and conditions of this Agreement shall continue as during the Employment Period,
except as you and Nabi may otherwise expressly agree in writing.

2. SALARY: Your salary will be $40,000 per month, payable bi-weekly during the
Employment Period and pro rated for any partial month during the Employment
Period. You will not receive director fees during the Employment Period, but you
will be entitled to receive during the Employment Period director fees for any
meeting commencing on or before the Effective Date.

3. BONUS: You will not be entitled to participate in Nabi’s VIP Management
Incentive Program or any other bonus plan maintained by Nabi during the
Employment Period, except as expressly provided in Section 4 of this Agreement.

4. EQUITY RELATED COMPENSATION:

(A) Nabi agrees to grant to you two awards of restricted shares of Nabi common
stock (the “Restricted Stock”) pursuant to the terms of Nabi’s 2000 Equity
Incentive Plan. The number of shares in each Restricted Stock award will be
determined by dividing the dollar amount of the award specified in Section 4D
and 4E, respectively, by the officially reported closing price for a share of
Nabi common stock as reported by Nasdaq for the Effective Date ($5.74), rounded
to the nearest whole share. In addition, Nabi will make cash

FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

 

payments (each a “Cash Bonus”) to you upon the vesting of each Restricted Stock
award in an amount equal to the aggregate value of the Restricted Stock that
vests under the respective Restricted Stock Agreement (as defined below). No
Cash Bonus will be paid with respect to any share of Restricted Stock that does
not vest.

(B) The agreements evidencing the Restricted Stock awards (each a “Restricted
Stock Agreement”) shall be in substantially the form of Nabi’s “Spot Restricted
Stock Agreement” filed most recently with the SEC and otherwise consistent with
the terms of this Agreement.

(C) The amount of each Cash Bonus shall equal the number of shares that vest
under the Restricted Stock Agreement, multiplied by the Market Value (as defined
below). As used in this Agreement, “Market Value” means the officially reported
closing price for a share of Nabi common stock as reported by the principal
exchange on which the common stock then is traded for the vesting date or, if
the common stock did not trade on such date, on the next preceding date for
which there is an officially reported closing price for the common stock. The
Cash Bonus shall be reduced by the amount that Nabi is obligated to withhold in
respect of any federal, state or local income taxes, or social security and
medicare taxes, payable by you on account of both the Cash Bonus and your
realization of any compensation income in connection with the vesting of any
shares of Restricted Stock. Nabi will pay the Cash Bonus, net of withheld taxes,
as soon as practicable after the vesting date under the applicable Restricted
Stock Agreement.

(D) Nabi will grant as of the Effective Date an award of $25,000 of Restricted
Stock, which award will vest fully upon the earlier of the Expiration Date and
Nabi’s termination of your employment without cause, and partially if you die or
Nabi terminates your employment under Section 7B of this Agreement on account of
a disability, provided that your death or the termination of your employment on
account a disability occurs after the third month anniversary of the Effective
Date and before the Expiration Date. If the award vests because of the
termination of your employment on account of your death or disability, the
number of shares of Restricted Stock that vest will be prorated based upon the
number of days elapsed in the Employment Period. For example, if you die one day
before the third month anniversary of the Effective Date, none of the shares of
Restricted Stock will vest; but if you die 120 days after the Effective Date,
and assuming for purposes of this illustration there are 180 days in the
Employment Period, two-thirds (2/3) of the shares of Restricted Stock will vest.

(E) Nabi will grant as of the Effective Date an award of $50,000 of Restricted
Stock, which award will vest upon the terms and conditions set forth in the
attached Exhibit A.

5. BENEFITS:

(A) During the Employment Period, you will be eligible to participate in such
fringe benefits programs as are accorded generally to other Nabi executive
officers.

(B) You hereby elect to participate, to the extent permissible, in the premium
payment option under Nabi’s cafeteria plan (as defined under section 125 of
Internal Revenue Code of 1986, as amended (the “Code”)). Provided that your
election to participate in such

plan remains in effect, Nabi will pay monthly for each month beginning during
the Employment Period up to $1,557 in healthcare insurance premiums on your
behalf under the Pfizer Inc. retiree health plan, with the intent that such
payments would be made on a pre-tax basis. If your participation in Nabi’s
cafeteria plan on the terms set forth in the immediately preceding sentence is
not permissible, Nabi will instead make a monthly payment to you, during each
month beginning during the Employment Period, in the amount of $1,557, which
payment shall be grossed-up for any applicable federal, state and local income
taxes, as well as social security and medicare taxes, and for any additional
taxes on account of the gross up, to the extent that such payment is
compensation income to you.

(C) Nabi will pay you monthly in arrears a per diem fee of $180 to cover food,
laundry, gas and other miscellaneous expenses while you are working at Nabi’s
headquarters in Boca Raton, Florida during the Employment Period. Your travel to
other Nabi facilities, including Rockville, Maryland, will be a reimbursable
business expense. The per diem fees will not be grossed-up for any applicable
federal, state or local income taxes, or any social security or medicare taxes.

(D) Nabi will reimburse you monthly in arrears upon written request for hotel or
other lodging, airfares and car rental expenses (other than gas expenses covered
by the per diem in Section 8C of this Agreement) reasonably incurred by you
while you are working at the Nabi’s headquarters in Boca Raton, Florida during
the Employment Period. Such reimbursement will be grossed-up for any applicable
federal, state and local income taxes and social security and medicare taxes,
and for any additional taxes on account of the gross up, in each case to the
extent that such reimbursement would be taxable to you.

(E) Nabi will pay up to $10,000 of legal fees and disbursements reasonably
incurred by you in connection with the negotiation of all employment-related
agreements, including this Agreement, Nabi’s Employee Invention Agreement, and
the Restricted Stock Agreements. Nabi will pay such legal fees and disbursements
directly to your counsel promptly after Nabi’s receipt of an invoice that you
have approved from such counsel.

(F) Reimbursement of expenses under Sections 5(C) and 5(D) of this Agreement
(but not the per diem payment) shall be subject to periodic review by Nabi’s
Audit Committee. You agree to use reasonable efforts to maintain adequate
records of all reimbursable expenses necessary to satisfy any reporting
requirements of the Code, and applicable Treasury regulations.

6. DUTIES AND EXTENT OF SERVICES:

(A) During the Employment Period, you agree to devote substantially all of your
working time, and such energy, knowledge, and efforts as is necessary, to the
discharge and performance of your duties as provided in this Agreement. You
shall be located primarily in Nabi’s Boca Raton, Florida facilities, but shall
travel to other locations from time to time as shall be reasonably required in
the course of performance of your duties.

(B) During the Employment Period, you shall serve as interim President and Chief
Executive Officer. Subject to the direction and supervision of Nabi’s Board of
Directors and any committee thereof, you shall have full discretionary authority
during the Employment Period to control Nabi’s day-to-day operations and to
incur such obligations on behalf of Nabi as may be required in the ordinary
course of business. You shall also have such other duties as the Nabi Board of
Directors or any committee thereof may reasonably delegate to you, provided that
such duties shall be reasonably consistent with those duties assigned to chief
executive officers in organizations comparable to Nabi.

(C) You represent and agree that your employment by Nabi and your performance of
all the terms of this Agreement will not conflict with or violate any agreement
that you may have with any other party; and that you will not disclose to Nabi
or induce Nabi to use any confidential or proprietary information or material
belonging to any previous employer or other party.

7. TERMINATION:

(A) The Employment Period shall terminate upon your death. You may also
terminate the Employment Period upon thirty (30) days’ prior written notice to
Nabi.

(B) Nabi may terminate the Employment Period (a) in the event Nabi reasonably
determines that you are unable to perform the essential functions of your
position, with or without reasonable accommodation, for any four (4) consecutive
weeks as the result of mental or physical incapacity or (b) for “cause”, which
is defined as (i) any act of fraud or embezzlement or any other felonious act by
you that either (a) involves Nabi or (b) in the case of any such act not
involving Nabi, is the subject of an indictment or conviction of you or a nolo
contendere plea by you and the Nabi Board of Directors determines in good faith
that such indictment, conviction or plea could reasonably be expected to have a
material adverse effect on your business reputation or have a material adverse
effect on Nabi, (ii) your refusal to comply with reasonable directions in
connection with the performance of your duties as provided for in Section 6 of
this Agreement after written notice of such failure is delivered to you,
(iii) failure to comply in any material respect with the provisions of Section 9
of this Agreement or (iv) your gross negligence in connection with the
performance of your duties as provided for in this Agreement with regard to a
material matter, provided that, in the event of a proposed termination under
clause (ii) or clause (iv) of this clause (B), you shall receive ten (10) days’
prior written notice of such proposed termination and within such period you
shall be afforded an opportunity to be heard by Nabi’s Board of Directors or a
duly appointed committee of the Board as to whether grounds for termination
under these clauses exists.

(C) Nabi may otherwise terminate the Employment Period upon thirty (30) days’
prior notice to you.

(D) Your confidentiality agreement set forth in Sections 9 below and your
agreement to cooperate set forth in Section 10 below shall survive the
termination of your employment regardless of the reasons therefor.

1. SEVERANCE; 409A:

(A) In the event that your employment terminates for any reason, including a
termination without cause pursuant to Section 7C of this Agreement or after the
expiration of the Employment Period, you will not be entitled to receive any
severance or other payment on account of such termination except as expressly
provided in Section 8B of this Agreement.

(B) If Nabi terminates your employment without cause, including because Nabi
hires a President and Chief Executive Officer to succeed you, Nabi will make a
lump sum payment to you, which payment shall be made on or as soon as
practicable after the later of the effective date of your termination and the
end of the deferral period provided in Section 8C of this Agreement in an amount
equal to the salary that you would have received if Nabi had continued to employ
you through the Expiration Date. No payment will be due under this Section 8B if
you and Nabi mutually agree that you will serve as the non-interim President
and/or Chief Executive Officer.

(C) You and Nabi intend that the provisions of this Agreement and all amounts
payable to you under this Agreement meet the requirements of Section 409A of the
Code to the extent applicable, and this Agreement shall be interpreted in
accordance with such intent. Without limiting the scope of the immediately
preceding sentence, the lump sum payment provided for under Section 8B of this
Agreement shall be deferred for six months from the effective date of your
termination if immediately prior to such termination you are, or in Nabi’s sole
opinion may be, a “specified employee” (as that term is defined in
Section 409A(a)(2)(B)(i) of the Code) and such deferral is necessary to avoid
the imposition of taxes on you under Section 409A of the Code.

9. CONFIDENTIALITY:

(A) You acknowledge that your duties with Nabi will give you access to trade
secrets and other confidential information of Nabi and/or its affiliates and of
third parties, including but not limited to information concerning composition,
production and marketing of their respective products, customer lists, and other
information relating to their present or future operations (all of the
foregoing, whether or not it qualifies as a “trade secret” under applicable law,
is collectively called “Confidential Information”). You recognize that
Confidential Information is proprietary to each such entity and gives each of
them significant competitive advantage.

(B) You agree not to use or disclose any of the Confidential Information during
or after the Employment Period, except for the sole and exclusive benefit of the
relevant company and except as may be required by law. Upon Nabi’s request, you
will return to the relevant company’s office after the termination of the
Employment Period all documents, computer electronic information and files,
e.g., diskettes, floppies etc. and other tangible embodiments of any
Confidential Information.

(C) You agree that Nabi would be irreparably injured by any breach of your
confidentiality agreement in this Section 9, that such injury would not be
adequately compensable by monetary damages, and that, accordingly, the offended
company may specifically enforce the provisions of this Section by injunction or
similar remedy by any court of competent jurisdiction without affecting any
claim for damages.

(D) If you are legally compelled or otherwise required by a court or regulatory
body to disclose any Confidential Information, you will provide Nabi and, if
applicable, any other relevant company with prompt written notice of such
request, so that the relevant company may seek, at its sole cost and expense, an
appropriate protective order or other appropriate remedy. You agree to use
commercially reasonable efforts, at the sole cost and expense of the relevant
company, to cooperate with such company in its efforts to obtain such protective
order or other remedy. In the event that such protective order or other remedy
is not obtained, you may furnish that portion (and only that portion) of the
Confidential Information that, upon the advice of your counsel, you are legally
compelled or otherwise required to disclose.

10. LITIGATION AND REGULATORY COOPERATION: During and after your employment with
Nabi, you shall reasonably cooperate with Nabi in the defense or prosecution of
any claim now in existence or which may be brought in the future against or on
behalf of Nabi which relates to any event or occurrence that transpired while
you were employed by Nabi; provided, however, that such cooperation shall not
materially and adversely affect you or expose you to an increased probability of
civil or criminal litigation. Your cooperation in connection with such claims or
actions shall include, but not be limited to, being available to meet with
counsel to prepare for discovery or trial and to act as a witness on behalf of
Nabi at mutually convenient times. During and after your employment with Nabi,
you also shall cooperate fully with Nabi in connection with any investigation or
review of any federal, state or local regulatory authority as any such
investigation or review relates to events or occurrences that transpired while
you were employed by Nabi. Nabi shall reimburse you for all out-of-pocket costs
and expenses incurred in connection with your performance under this Section 10,
including, but not limited to, reasonable attorneys’ fees and costs.

11. INDEMNIFICATION: Reference is made to that certain Indemnification Agreement
dated September 6, 2005 between you and Nabi (the “Indemnification Agreement”)
under which Nabi agreed, among other things, to indemnify you and hold you
harmless with respect to any action taken or omitted by you in your capacity as
a Nabi director, to the fullest extent permissible under applicable law, as such
law may be amended or supplemented from time to time. You and Nabi hereby agree
that the Indemnification Agreement shall apply equally to any action taken or
omitted by you in your capacity as an officer, employee or agent of Nabi or as a
director, officer, employee, member, manager, trustee (or other fiduciary) or
agent of any other corporation, limited liability company, partnership, joint
venture, trust or other entity or enterprise, whether or not for profit, or any
employee benefit plan (or related trust) sponsored or maintained by Nabi or any
subsidiary, as to which you are or were serving in one or more such capacities
at the request of Nabi or any of its subsidiaries. You and Nabi further agree
that this sentence is intended to be and shall be construed as an amendment of
the Indemnification Agreement within the meaning of Section 18 of the
Indemnification Agreement.

Effective February 15, 2007

This Exhibit A is incorporated by reference into Section 4E of the Employment
Agreement (the “Agreement”), effective as of February 15, 2007, between Nabi
Biopharmaceuticals (“Nabi”) and Les Hudson, Ph.D. (the “Officer”). Any

In accordance with Section 4E of the Agreement, Nabi will grant as of the
Effective Date an award of $50,000 of Restricted Stock (the “Performance Award”)
to the Officer.

Performance Goals and Weighting for the Performance Award

The Restricted Stock Agreement evidencing the Performance Award will provide
that the Performance Award will vest upon the occurrence of the respective goals

Other Vesting Provisions for the Performance Award

Termination Without Cause During Employment Period

The Restricted Stock Agreement for the Performance Award will provide that if
during the Employment Term Nabi terminates the Officer’s employment without
cause the Performance Award will vest fully.

Termination Upon Death or Disability During Employment Period

The Restricted Stock Agreement for the Performance Award will also provide that
if during the Employment Term the Officer dies or Nabi terminates the Officer’s
employment under Section 7B of the Agreement on account of a disability, in each
case after the third month anniversary of the Effective Date and before the
Expiration Date, the number of shares of Restricted Stock under the Performance
Award that will vest will be prorated based upon the number of days elapsed in
the Employment Period and assuming the achievement of each of the performance
goals specified on this Exhibit. For example, if the Officer dies one day before
the third month anniversary of the Effective Date, none of the shares of
Restricted Stock comprising the Performance Award will vest; but if the Officer
dies 120 days after the Effective Date, and assuming for purposes of this
illustration there are 180 days in the Employment Period, two-thirds (2/3) of
all of the shares of Restricted Stock under Performance Award will vest.
