Undertakings. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted against such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the Prospectus any facts or events arising after the effective date of the registration statement (or the most recent post- effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that clauses (i) and (ii) do not apply if the information required to be included in a post-effective amendment by these clauses is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering; and (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. -7- SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Boca Raton, State of Florida, on the 25th day of July, 2000.

connection therewith or as a condition thereto to qualify to do business or
subject itself to taxation or to file a general consent to service of process in
any such jurisdictions.

          (e)  Notify promptly the Holders of Registrable Securities to be sold,
(and in the case of (i)(A) in no event less than two business days prior to such
filing) and (if requested by any such person) confirm such notice in writing,
(i)(A) when a prospectus or any prospectus supplement or post-effective
amendment is proposed to be filed, and, (B) with respect to a Registration
Statement or any post-effective amendment, when the same has become effective,
(ii) of any request by the SEC or any federal or state governmental authority
for amendments or supplements to a Registration Statement or related prospectus
or for additional information, (iii) of the issuance by the SEC of any stop
order suspending the effectiveness of a Registration Statement or the initiation
of any proceedings for that purpose, (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any proceeding for such
purpose, and (v) of the happening of any event that makes any statement made in
such Registration Statement or related prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material respect
or that requires the making of any changes in such Registration Statement,
prospectus or documents so that, in the case of the Registration Statement, it
will not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, not misleading, and that in the case of the prospectus, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading.

          (f)  Use its reasonable best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of, any order suspending the effectiveness of a
Registration Statement, or the lifting of any suspension of the qualification
(or exemption from qualification) of any of the Registrable Securities for sale
in any jurisdiction, at the earliest practicable moment.

                                      -3-


          (g)  If requested by the holders of a majority of the Registrable
Securities being sold in connection with such offering, (i) promptly incorporate
in a prospectus supplement or post-effective amendment such information as the
holders reasonably request should be included therein regarding such holders or
the plan of distribution of the Registrable Securities, and (ii) make all
required filings of the prospectus supplement or such post-effective amendment
as soon as practicable after the Company has received notification of such
matters to be incorporated in such prospectus supplement or post-effective
amendment: provided, however, that the Company shall not be required to take any
action pursuant to this Section 2.1(g) that would, in the opinion of outside
counsel for the Company, violate applicable law.

          (h)  Upon the occurrence of any event contemplated by Section
2.1(e)(v), as promptly as practicable, prepare a supplement or amendment,
including a post-effective amendment, to each Registration Statement or a
supplement to the related prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, such prospectus will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

          (i)  Use its reasonable best efforts to cause all Registrable
Securities relating to such Registration Statement to be listed on each
securities exchange or automated quotation system, if any, on which similar
securities issued by the Company are then listed.

     2.2  Seller Information.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Registration
Rights Agreement with respect to Registrable Securities of any selling Holder
that such Holder shall furnish to the Company such information regarding such
Holder, such Holder's Registrable Securities and such Holder's intended method
of disposition as the Company may from time to time reasonably request; provided
that such information shall be used only in connection with such registration.

          If the Registration Statement refers to any Holder by name or
otherwise as the Holder of any securities of the Company, then such Holder shall
promptly (i) notify the Company and its counsel of the existence of any fact of
which such Holder becomes aware and the happening of any event which relates to
Holder or the distribution of the securities owned by such Holder which results
in the Registration Statement containing an untrue statement of material fact or
omitting to state a material fact required to be stated therein or necessary to
make any statements therein not misleading, or the Prospectus included in such
Registration Statement containing an untrue statement of material fact or
omitting to state a material fact required to be stated therein or necessary to
make any statements therein, in light of the circumstances under which they were
made, not misleading, and (ii) provide to the Company such information which
relates to Holder or the distribution of the securities owned by such Holder as
shall be necessary to enable the Company to prepare a supplement or post-
effective amendment to such Registration Statement or related Prospectus or any
document incorporated therein by reference or file any other documents required
so that such Registration Statement

                                      -4-


will not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and such Prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

     2.3  Notice to Discontinue. Each holder of Registrable Securities agrees
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 2.1(e)(ii) through (v), such Holder shall
forthwith discontinue disposition of Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until such Holder's
receipt of the copies of the supplemented or amended prospectus contemplated by
Section 2.1(h) and, if so directed by the Company, such Holder shall deliver to
the Company (at the Company's expense) all copies, other than permanent file
copies, then in such Holder's possession of the Prospectus covering such
Registrable Securities which is current at the time of receipt of such notice.
If the Company shall give any such notice, the Company shall extend the period
during which such Registration Statement shall be maintained effective pursuant
to this Registration Rights Agreement by the number of days in excess of ten
(10) business days during the period from and including the date of the giving
of such notice pursuant to Section 2.1(e) to and including the date when the
Holder shall have received the copies of the supplemented or amended prospectus.

     2.4  Expenses of Registration. Except only as specifically provided herein,
all expenses incident to the performance of compliance with this Registration
Rights Agreement by the Company shall be borne by the Company, regardless of
whether the Registration Statement becomes effective, including, without
limitation, (i) all registration and filing fees and expenses (including filings
made with the National Association of Securities Dealers ("NASD"), if
applicable); (ii) fees and expenses (including fees and expenses of counsel) of
compliance with federal securities and state Blue Sky and other Canadian,
provincial or other securities laws; (iii) expenses of printing, messenger and
delivery services, duplication, word processing and telephone incurred by the
Company (but not by the holders of Registrable Securities); (iv) fees and
disbursements of counsel for the Company; (v) all application and filing fees in
connection with listing Common Shares on a national securities exchange or
automated quotation system pursuant to the requirements hereof; and (vi) all
fees and disbursements of independent certified public accountants of the
Company (including the expenses of any special audit and "cold comfort" letters
required by or incident to such performance). The Company will, in any event,
bear its own internal expenses (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties),
the expenses of any annual audit and the fees and expenses of any person,
including special experts, retained by the Company.  All underwriting discounts
and commissions relating to the Registrable Securities and the fees and
disbursements of counsel for the selling Holders shall be borne and paid by the
selling Holders of such Registrable Securities.

                                      -5-


     2.5  Indemnification.

          (a)  Indemnification by Company. To the extent permitted by law, the
Company will indemnify and hold harmless each Holder, the partners, officers and
directors of each Holder and each person, if any, who controls such Holder
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation") by the Company: (i) any
untrue statement or alleged untrue statement of a material fact contained in the
Registration Statement or any amendments or supplements thereto, or the omission
or alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein not misleading, (ii) any
untrue statement or alleged untrue statement of a material fact contained in the
Prospectus (including any preliminary, final or summary prospectus, amendment or
supplement thereto) included in such Registration Statement or any omission or
alleged omission to state a material fact required to be stated therein or
necessary to make any statement therein, in light of the circumstances under
which they were made, not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law in connection with the offering
covered by the Registration Statement; provided, however, that the Company will
not be liable for indemnification in any such case to the extent (and only to
the extent) that any losses, claims, damages or liabilities arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
or omission or alleged omission of a material fact so made in reliance upon and
in conformity with written information furnished to the Company by such Holder
under an instrument duly executed by such Holder and stated to be specifically
for use in connection with such registration. The Company will pay to each such
Holder, partner, officer, director or controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action promptly as
incurred.

          (b)  Indemnification by Holder of Registrable Securities. To the
extent permitted by law, each Holder will, if Registrable Securities held by
such Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify and hold harmless the
Company, each of its directors, its officers, agents and each person, if any,
who controls the Company within the meaning of the Securities Act against any
losses, claims, damages or liabilities (joint or several) to which the Company
or any such director, officer, agent or controlling person may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by such Holder under an
instrument duly executed by such Holder and stated to be specifically for use in
connection with such

                                      -6-


registration; and each such Holder will pay as incurred any legal or other
expenses reasonably incurred by the Company or any such director, officer,
agent, controlling person or other person in connection with investigating or
defending any such loss, claim, damage, liability or action if it is judicially
determined that there was such a Violation; provided, however, that in no event
shall any indemnity under this Section 2.5(b) exceed the dollar amount of net
proceeds from the offering received by such Holder.

          (c)  Conduct of Indemnification Proceedings. Promptly after receipt by
an indemnified party under this Section 2.5 of notice of the commencement of any
action (including any governmental action), such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 2.5, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party shall have the right to retain its own counsel, with
the fees and expenses to be paid by the indemnifying party, if, in the
reasonable judgment of any such indemnified party, based upon advice of counsel,
a conflict of interest may exist between such indemnified party and the
indemnifying party with respect to such claims (in which case, if the
indemnified party notifies the indemnifying party in writing that it elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such claim
on behalf of such indemnified party; provided, however, that the indemnified
party shall be entitled to elect only one counsel at the expense of the
indemnifying party and such counsel shall be reasonably acceptable to the
indemnifying party). The failure to deliver written notice to the indemnifying
party within a reasonable time of the commencement of any such action, if it is
finally determined in a court of competent jurisdiction (which determination is
not subject to appeal) that such failure is materially prejudicial to its
ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party under this Section 2.5, but the omission so
to deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 2.5. No indemnifying party shall be liable for any settlement of any
claim or action effected without its written consent.

          (d)  Contribution. If the indemnification provided for in this Section
2.5 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any losses, claims, damages or liabilities
referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party thereunder, shall to the extent permitted by applicable law
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability in such proportion as is appropriate to
reflect the relative fault of the indemnifying party on the one hand and of the
indemnified party on the other in connection with the Violation(s) that resulted
in such loss, claim, damage or liability. The relative fault of the indemnifying
party and of the indemnified party shall be determined by a court of law by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission to state a material fact relates to
information supplied by the indemnifying

                                      -7-


party or by the indemnified party and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission; provided, that in no event shall any contribution by a Holder
hereunder exceed the dollar amount of net proceeds from the offering received by
such Holder. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of fraudulent misrepresentation
within the meaning of such Section 11(f).

          (e)  Survival; Settlement. The obligations of the Company and Holders
under this Section 2.5 shall survive completion of any offering of Registrable
Securities in a registration statement and the termination of this Registration
Rights Agreement. No indemnifying party, in the defense of any such claim or
litigation, shall, except with the consent of each indemnified party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

3.   Rule 144

     The Company covenants that it will use its reasonable best efforts to file
in a timely manner the reports required to be filed by it (if so required) under
the Securities Act and the Exchange Act and the Rules and Regulations adopted by
the SEC thereunder and, if at any time the Company is not required to file such
reports, it will, upon the request of any Holder of Registrable Securities, make
publicly available other information so long as necessary to permit sales
pursuant to Rule 144 under the Securities Act. Upon the request of any Holder of
Registrable Securities, the Company will deliver to such Holder a written
statement as to whether it has complied with such information requirements.

4.   Liquidated Damages

          (a)  The Company acknowledges and agrees that the Holders of
Registrable Securities will suffer damages, and that it would not be feasible to
ascertain the extent of such damages with precision, if the Company fails to
fulfill certain of its obligations hereunder. Accordingly, if (i) the
Registration Statement has not been filed with the Commission within 15 business
days after the Closing, or (ii) the Registration Statement is declared effective
but shall thereafter cease to be effective without being succeeded within 30
days by any additional Registration Statement filed within 30 days after the
prior Registration Statement has ceased to be effective (each such event
referred to in clauses (i) and (ii), a "Registration Default"), the Company
agrees to pay liquidated damages to each Holder of Registrable Securities,
during the week immediately following the occurrence of such Registration
Default in an amount equal to $.024 per week (or partial week) per Common Share
of Registrable Securities held by such Holder. All accrued liquidated damages
shall be paid to Holders by wire transfer of immediately available funds or by
federal funds check by the Company. Following the cure of all Registration
Defaults, the accrual of liquidated damages will cease to accrue.

                                      -8-


          (b)  All of the obligations of the Company set forth in this Section 4
that are outstanding with respect to any Registrable Security at the time such
security ceases to be a Registrable Security shall survive until such time as
all such obligations with respect to such security shall have been satisfied in
full.

5.   Miscellaneous

     5.1  Governing Law. This Registration Rights Agreement shall be governed by
and construed under the laws of the State of Delaware as applied to agreements
among Delaware residents entered into and to be performed entirely within
Delaware.

     5.2  Survival. The representations, warranties, covenants, and agreements
made herein shall survive any investigation made by any Holder and the closing
of the transactions contemplated hereby.

     5.3  Successors and Assigns. Except as otherwise expressly provided herein,
the provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors, and administrators of the parties hereto
and shall inure to the benefit of and be enforceable by each Permitted Assignee
of Registrable Securities from time to time. A "Permitted Assignee" shall mean
(i) with respect to any Investor, any other person directly or indirectly
controlling or controlled by or under direct or indirect, common control with
such Investor, (ii) the spouse, sibling, child, step-child, grandchild, niece,
nephew or parent of the Investor, or the spouse thereof, and (iii) any
transferee or assignee of not less than 50,000 shares of Registrable Securities
(as presently constituted and subject to subsequent adjustment for stock splits,
stock dividends, reverse stock splits, and the like).

     5.4  Entire Agreement. This Registration Rights Agreement, including any
exhibits hereto, the Purchase Agreement and the other documents delivered
pursuant thereto constitute the full and entire understanding and agreement
between the parties with regard to the subject matter hereof and no party shall
be liable or bound to any other in any manner by any representations,
warranties, covenants and agreements except as specifically set forth herein and
therein.

     5.5  Severability. In case any provision of this Registration Rights
Agreement shall be invalid, illegal, or unenforceable, the validity, legality,
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby.

     5.6  Amendment and Waiver. The provisions of this Registration Rights
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Company has obtained the written
consent of Holders of at least a majority of the then outstanding Registrable
Securities; provided, however, that Sections 2.1 and 2.5 shall not be amended,
modified or supplemented, and waivers or consents to departures from this

                                      -9-


proviso may not be given, unless the Company has obtained the written consent of
each Holder of the then outstanding Registrable Securities.

     5.7  Delays or Omissions. It is agreed that no delay or omission to
exercise any right, power or remedy accruing to any Holder, upon any breach,
default or noncompliance of the Company under this Registration Rights Agreement
shall impair any such right, power or remedy, nor shall it be construed to be a
waiver of any such breach, default or noncompliance, or any acquiescence
therein, or of any similar breach, default or noncompliance thereafter
occurring. It is further agreed that any waiver, permit, consent or approval of
any kind or character on any Holder's part of any breach, default or
noncompliance under the Agreement or any waiver on such Holder's part of any
provisions or conditions of this Registration Rights Agreement must be in
writing and shall be effective only to the extent specifically set forth in such
writing. All remedies, either under this Registration Rights Agreement, by law,
or otherwise afforded to Holders, shall be cumulative and not alternative.  No
Holder shall have any right to obtain or seek an injunction restraining or
otherwise delaying any registration as the result of any controversy that might
arise with respect to the interpretation or implementation of this Registration
Rights Agreement.

Gentlemen/Ladies:

     Reference is made to that certain Registration Statement on Form S-3 (the
"Registration Statement") which Nabi (the "Company") is filing on the date
hereof with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "Securities Act"), with respect to the resale of up to
1,666,667 shares (the "Shares") of the Company's common stock, $.10 par value
per share.

     We have acted as counsel for the Company in connection with the
Registration Statement.  We have examined such documents and made such other
investigation as we have deemed appropriate to render the opinion set forth
below.  As to matters of fact material to our opinion, we have relied, without
independent verification, on certificates and other inquiries of officers of the
Company. We are of the opinion that the Shares to be sold by the selling
security holders are duly and validly issued, fully paid and non-assessable.

     We understand that this letter is to be used in connection with the
Registration Statement, as finally amended, and hereby consent to the filing of
this letter with and as a part of the Registration Statement as so amended, and
to the reference to our firm in the Prospectus under the heading "Legal
Matters."  It is understood that this letter is to be used in connection with
the resale of the aforesaid Shares only while the Registration Statement is
effective as so amended and as it may be amended from time to time as
contemplated by Section 10(a)(3) of the Securities Act.

                              Very truly yours,
