ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

On September 6, 2001, we sold the operating assets of a majority of our antibody
collection business and our testing laboratory (collectively the "Transferred
Antibody Collection Business") to CSL Limited ("CSL") for $152 million in cash,
subject to closing adjustments (as of September 6, 2001, these closing
adjustments resulted in the receipt of an additional $1 million in cash by us).
The assets sold were certain real estate, leasehold interests, fixtures,
furniture, tools, machinery and equipment, other fixed assets, plasma
inventories and related supplies, contracts, agreements, arrangements and/or
commitments, licenses and permits, business and financial records, intellectual
property and goodwill related to the operation of 47 of our current 56 antibody
collection centers and our testing laboratory. The purchase price we received
was the result of arm's-length bargaining between CSL and us. There is no
material relationship between CSL and us or, to our knowledge, between CSL and
any of our affiliates, any of our Directors or officers or any associate of any
such Director or officer.

We have requested confidential treatment of the redacted portions of this exhibit pursuant to Rule 24b-2 under the Securities Exchange Act of 1934, as amended, and have separately filed a complete copy of this exhibit with the Securities and Exchange Commission. 2.2 First Amendment to Agreement for Purchase and Sale of Assets SIGNATURES Pursuant to the requirements of the Securities and Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized. Nabi (Registrant) Date: September 21, 2001 By: /s/ Mark L. Smith ------------------------------------- Mark L. Smith Senior Vice President, Finance and Chief Financial Officer 2 3 ITEM 7(b) CONDENSED CONSOLIDATED PRO FORMA FINANCIAL INFORMATION INTRODUCTION On September 6, 2001, we completed the sale of the operating assets of 47 of our antibody collection centers and the majority of our testing laboratory (collectively the "Transferred Antibody Collection Business") to CSL Limited ("CSL"). Total cash proceeds from the sale were $153 million, after closing adjustments as of the time of sale pursuant to the Asset Purchase Agreement, dated June 25, 2001, as amended. Further closing adjustments will be made as provided for in the agreement. We applied $18 million of the proceeds to pay back all of our short-term debt as of the closing date which comprised a revolving credit facility and a term loan. The remaining proceeds will be used for working capital and other corporate purposes, and may be used to position us to accelerate the development of our research and development pipeline and to acquire or in-license additional biopharmaceutical products. For purposes of this document, the unaudited condensed consolidated pro forma balance sheet of Nabi set forth below is used to show the effects of the sale of the Transferred Antibody Collection Business as if it occurred on June 30, 2001 based on certain estimates and assumptions. The unaudited condensed consolidated pro forma balance sheet includes pro forma adjustments to give effect to the disposition of assets and the use of proceeds as though they had occurred as of June 30, 2001. We used June 30, 2001 because it marks the end of the latest fiscal period for which financial information is publicly available. The accompanying unaudited condensed consolidated pro forma income statements for the six months ended June 30, 2001 and the year ended December 30, 2000 assume that the assets were disposed of as of January 1, 2000 and eliminates the estimated historical results of operations of the Transferred Antibody Collection Business from the historical results of operations of Nabi for the six months ended June 30, 2001 and the year ended December 30, 2000, and the interest expense related to the short-term debt that was repaid with the proceeds. The accompanying pro forma information should be read in conjunction with our annual report on Form 10-K for the fiscal year ended December 30, 2000, the quarterly report on Form 10-Q for the period ended June 30, 2001 and the current report on Form 8-K filed on July 10, 2001. The pro forma information is not necessarily indicative of the results that would actually have occurred had this transaction been consummated on the dates or for the periods indicated or that may occur in the future. For example, lower antibody product margins in 2000 reflect higher costs of production including higher donor fees and increased cost of regulatory compliance as discussed in our 2000 Form 10-K. Further, had the transaction occurred on January 1, 1999, the Pro Forma Sales less Costs of Products Sold would have been $12 million for the year ended December 31, 1999 as compared to Pro Forma Sales less Pro Forma Costs of Products Sold of ($4) million for the year ended December 30, 2000. 3 4 Nabi CONDENSED CONSOLIDATED PRO FORMA BALANCE SHEET (unaudited, amounts in thousands)

or purchase order, commitment, property interest, qualification or other Asset
described in Section 1.1, and not otherwise excluded in Section 1.2, that is to
be sold, assigned, transferred or conveyed to, or assumed by, the Buyer hereby
cannot be sold, assigned, transferred, conveyed or assumed without the approval,
consent or waiver of any third person (including any government or governmental
unit), or if such sale, assignment, transfer, conveyance or assumption would
constitute a breach thereof or a violation of any law, decree, order, regulation
or other governmental edict, this Agreement shall not (unless and until such
consent, approval or waiver is obtained) constitute a sale, assignment,
transfer, conveyance or assumption thereof, or an attempted sale, assignment,
transfer, conveyance or assumption thereof; provided, however, that the Seller
shall make arrangements reasonably satisfactory to the Buyer to provide the
benefits of any such lease, contract, agreement, sales or purchase order,
commitment, property interest, qualification or other Asset described in Section

the Buyer has not agreed in writing to reimburse.

                  (b) The Seller shall not be obligated to sell, assign,
transfer or convey to the Buyer any of its rights and obligations in and to a

1.3(a) necessary to sell, assign, transfer or convey the Assets to the Buyer as
soon as practicable; provided, however, that the Seller shall not be obligated
to make any financial concessions to any third party from whom such approval,
consent or waiver is requested; and provided further, that in obtaining such
consents, the Seller shall not, without the Buyer's prior written consent, agree
or enter into any material modification or amendment to any contract, lease or
other agreement relating to any of the Assets.

         1.4. OBTAINING PERMITS AND LICENSES. The Buyer shall be responsible for
obtaining all permits and licenses required by any governmental agency with
respect to the Centers, the Laboratory or the Assets after the Closing. The
Seller will cooperate reasonably with the Buyer in obtaining such permits and
licenses. At the Closing, to the extent permitted by law, the Seller shall
transfer such permits and licenses to the Buyer. To the extent that any such
permits or licenses cannot be lawfully transferred to the Buyer, the Seller
shall have the right to cancel such non-transferable permits or licenses or any
bonds, guarantees or undertakings by the Seller now applicable to the Centers,
the Laboratory or the Assets; provided, however, that to the extent permitted by
law the Seller shall allow the Buyer to operate under such permits and licenses
for a term of one hundred eighty (180) days following the Closing, and the
Seller shall make no such cancellation during such time.

         2.2. NO OTHER LIABILITIES OR OBLIGATIONS ASSUMED. The Buyer does not
assume and shall not be liable for any liabilities or obligations of the Seller
other than as set forth in Section 2.1. The Seller shall remain responsible for
all liabilities and obligations related to the Transferred Antibody Collection
Business arising prior to the Closing Date except for the Assumed Employee

                                       4
   6

such other date, place and time as may be agreed upon by the parties, it being
understood that the parties shall endeavor to close at the earliest practicable
date, time being of the essence of this Agreement. The term "Closing Date" shall
mean the date the Closing takes place and the transactions provided for herein
shall be effective as of the close of business on the Closing Date.

         3.2. PURCHASE PRICE.

                  (a) In full consideration of the sale, transfer, assignment,
conveyance and delivery of the Assets, and subject to the terms and conditions
of this Agreement, the Buyer shall pay to the Seller at the Closing the amount
of One Hundred Fifty Two Million Dollars (US$152,000,000) (the "Purchase
Price"), subject to adjustment as hereinafter provided in this ARTICLE III, by
wire transfer of immediately available funds to the bank account or accounts
specified by the Seller for such purpose.

                  (b) The following items are to be adjusted between the Buyer
and the Seller as of 11:59 p.m. of the day immediately preceding the Closing
Date with respect to the Real Properties.

                           (i) real property taxes and assessments, on the basis
of the fiscal year for which assessed;

                           (ii) water rates and charges;

                           (iii) sewer taxes and rents;

                           (iv) common area maintenance costs, enclosed mail
charges, merchants' association dues and all other fees, charges, rents,
payments, costs or expenses due pursuant to any agreement affecting any Real
Property;

                           (v) electricity charges and all other utilities which
are supplied to the Real Properties;

                           (vi) personal property taxes, if any;

                           (vii) base, minimum, ground, additional and
percentage rents payable and receivable pursuant to the Leases;

                           (viii) fuel, if any, and all taxes thereon, on the
basis of readings taken as close as possible to the Closing Date;

                           (ix) deposits with utility companies and fees and
charges for transferable governmental permits and licenses;

                           (x) security deposits under all Leases;

                           (xi) cash on hand at the Centers; and




                                       5

                           (xii) except as may be otherwise provided herein, all
other expenses incurred in connection with the operation by the Seller of any of
the Real Properties shall be prorated as of 11:59 p.m. on the day preceding the
Closing Date, with the result that those expenses that are attributable to the
period prior to the Closing Date shall be the obligation of the Seller and those
attributable to the period from and after the Closing Date shall be the
obligation of the Buyer.

To the extent reasonably practicable, all such adjustments shall be reflected in
the Purchase Price paid at the Closing; otherwise, they shall be made through
payments by the Seller to the Buyer or by the Buyer to the Seller, as the case
may be, from time to time as items become ascertainable, in each case without
interest.

         3.3. ALTERNATIVE ARRANGEMENTS. If the Seller is unable at Closing for
any reason whatsoever to assign and transfer a particular Center to the Buyer,
including without limitation due to the failure of any landlord to consent to
the transfer of a lease relating to a particular Center, then the transactions
contemplated by this Agreement shall nevertheless proceed and the Seller shall
assign and transfer the Assets relating to any such Center which can be assigned
and transferred, excluding the Assets which cannot be assigned or transferred,
without any reduction in the Purchase Price; provided that (i) the Seller shall
make arrangements regarding any or all such excluded Assets for the Buyer
pursuant to Section 1.3(a), pursuant to a management agreement or other
structure reasonably acceptable to the Buyer and the Seller, and (ii) if at any
time after the Closing Date the Seller can lawfully assign and transfer a
particular excluded Asset to the Buyer, then the Seller shall without additional
consideration promptly assign and transfer to the Buyer such excluded Asset.

         3.4. [RESERVED.]

         3.5. ADJUSTMENT OF PURCHASE PRICE BASED ON ASSUMED EMPLOYEE LIABILITIES
AND PLASMA INVENTORY.

                  (a)(i) Nine months after the Closing Date (or if such date is
not a business day, on the first business day following nine months after the
Closing Date), the Buyer shall deliver to the Seller a schedule setting forth in
reasonable detail (i) the amount of Assumed Employee Liabilities actually paid
by the Buyer during such nine-month period and (ii) the amount of Assumed
Employee Liabilities the Buyer reasonably believes in good faith it may yet have
to pay ("Employee Liabilities Reserves") (the total of such amounts is
hereinafter referred to as the "Total Actual and Proposed Payment"). If the
Total Actual and Proposed Payment is less than one million dollars ($1,000,000),
the Buyer shall pay to the Seller within five business days, without interest,
the difference between one million dollars ($1,000,000) and the Total Actual and
Proposed Payment, and if the Total and Actual Proposed Payment is more than one
million dollars ($1,000,000), the Seller shall pay to the Buyer, within five
business days, without interest, the difference between one million dollars
($1,000,000) and the Total and Proposed Payment. If the Total Actual and
Proposed Payment (A) is more than one million dollars ($1,000,000) and (B)
includes Employee Liabilities Reserves which prove to be in excess of the
amounts actually paid by the second anniversary of the Closing Date, then on




                                       6
   8

such date (or if such date is not a business day, on the first business day
following such date) the Buyer shall pay to the Seller, with interest at the
prime rate from time to time published in The Wall Street Journal, from the date
of the Seller's earlier payment to the Buyer under this Section 3.5(a) until the
date payment is made, the difference between the amount of the Employee
Liabilities Reserves and the amount of the Employee Liabilities Reserves the
Buyer has actually paid. If the Total Actual and Proposed Payment (A) is more
than one million dollars ($1,000,000) and (B) includes Employee Liabilities
Reserves which prove to be less than the amounts actually paid, then the Seller
shall pay to the Buyer, on request, without interest, the difference between the
amount of the Assumed Employee Liabilities the Buyer has actually paid and the
aggregate amount the Seller has previously paid to the Buyer under this Section
3.5(a).

                           (ii) Upon the written request of the Seller, the
Buyer shall permit the Seller and its representatives to have access during
normal business hours to such records of the Buyer as may be reasonably
necessary to verify the accuracy of the schedule furnished to the Seller by the
Buyer pursuant to Section 3.5(a)(i) and other information relevant to determine
any payments which may be due under Section 3.5(a)(i). Such verification shall
be conducted at the Seller's expense and the Seller agrees that all information
obtained in connection therewith shall be held in confidence by it.

                  (b)(i) On the last Sunday prior to the Closing Date, a
physical inventory shall be taken of the Plasma Inventory under the joint
supervision of representatives of the Seller and the Buyer. Such inventory shall
then be corrected to the date of Closing and valued by the Seller at its cost in
accordance with accounting principles consistently applied by the Seller in
reflecting the cost of Plasma Inventory for purposes of its published financial
statements. If the value of the Plasma Inventory determined as provided in this
Section 3.5(b) exceeds ten million dollars ($10,000,000), on the thirtieth
business day following the Closing Date the Buyer shall pay to the Seller,
without interest, the amount of such excess, and if the value of the Plasma
Inventory determined as provided in this Section 3.5(b) is less than ten million
dollars ($10,000,000), the Seller shall pay on the thirtieth business day
following the Closing Date to the Buyer the amount of such deficiency, without
interest.

                           (ii) Upon the written request of the Buyer, the
Seller shall permit the Buyer and its representatives to have access during
normal business hours to such records of the Seller as may be reasonably
necessary to verify the accuracy of valuation contemplated by Section 3.5(b)(i).
Such verification shall be conducted at the Buyer's expense and the Buyer agrees
that all information obtained in connection therewith shall be held in
confidence by it.

         3.6. INSTRUMENTS OF CONVEYANCE. The sale, transfer, assignment,
conveyance and delivery of the Assets by the Seller to the Buyer shall be
effected by the execution and delivery of:




                                       7
   9

                  (a) a bill of sale and assumption of liabilities substantially
in the form attached hereto as Exhibit D; and

                  (b) such other documents and instruments of conveyance, sale,
transfer and assignment, in proper form for recording and in form and substance
reasonably satisfactory to counsel for the Buyer, as shall be necessary to sell,
transfer, assign and convey to, and to vest in, the Buyer, good and marketable
title to the Assets, free and clear of the security interests referred to in
Schedule 4.4(b).

         3.7. ALLOCATION OF PURCHASE PRICE. Prior to the Closing Date the
Purchase Price shall be allocated among the Assets as mutually agreed by the
Buyer and the Seller. The parties shall report all taxes in a manner consistent
with such allocation, and no party shall take any inconsistent position upon any
examination of any tax return, in any refund claim, or in any litigation,
investigation or otherwise.

                                   ARTICLE 4

Closing by the Seller in connection with the transactions contemplated hereby
will be duly executed and delivered by the Seller, will constitute the valid and
binding obligations of the Seller, and will be enforceable in accordance with
their respective terms. The execution, delivery and performance of this
Agreement does not, and all other agreements entered into in connection with the
transactions contemplated hereby by the Seller will not, violate, conflict with,
result in a breach of or constitute a default under (or an event which with due
notice or lapse of time, or both, would constitute a breach of or default under)
or result in the creation of




                                       8
   10

any lien, security interest or other encumbrance under (a) the Certificate of
Incorporation or By-laws of the Seller, as amended to date, (b) any note,
agreement, contract, license, instrument, lease or other obligation to which the

authorization, or waiver by or filing with any governmental agency is required
in connection with the execution or performance of this Agreement by the Seller
or the consummation by the Seller of the transactions contemplated hereby,
except such that the absence of which will not have a Material Adverse Effect.

         4.4. TITLE.

                  (a) Except as set forth in Schedule 4.4(a), the Seller has
good and marketable title to each parcel of Owned Property free and clear of all
liens, claims and encumbrances other than (i) imperfections of title, easements,
pledges, charges, restrictions and encumbrances, including without limitation,
survey matters and mechanics' liens, if any, that do not materially detract from
the value of the property subject thereto or materially interfere with the
manner in which it is currently being used in the Transferred Antibody
Collection Business or materially impair the operations of the Transferred
Antibody Collection Business, and (ii) taxes and general and special assessments
not in default and payable without penalty or interest.

                  (b) The Seller has good and marketable title to the Equipment,
Fixed Assets, Plasma Inventory and Supplies Inventory. Except to the extent set
forth in Schedule 4.4(b) attached hereto, the Equipment, Fixed Assets, Plasma
Inventory and Supplies Inventory are not subject to any mortgage, pledge, lien,
charge, security interest, encumbrance, restriction, lease, license, easement,
liability or adverse claim of any nature whatsoever, direct or indirect, whether
accrued, absolute, contingent or otherwise, except for those imperfections of
title and encumbrances, if any, that (a) are not substantial in character,
amount or extent and do not materially detract from the value of the properties
subject thereto; (b) do not materially and adversely interfere with either the
present or continued use of such property or materially and adversely affect the
conduct of normal operations of the Centers or the Laboratory; and (c) have
arisen only in the ordinary course of business.

the Assets shall be conveyed by the Seller to the Buyer at the Closing free and
clear of all liens, claims and encumbrances of any nature whatsoever which are
security for the payment of money.

hereto, neither the Seller nor, to the knowledge of the Seller, any other party
is in breach of or in default under any Contract or Lease, and there exists no
condition or event which after the



                                       9
   11

lapse of time or notice (or both) would constitute any such breach or default,
except for such breaches or defaults (if any) which would not have a Material
Adverse Effect.

adverse change in the Transferred Antibody Collection Business or any event or

on Schedule 4.7, the Transferred Antibody Collection Business or the Assets has
complied and is complying with all laws, ordinances, and governmental rules and
regulations applicable to it and its properties, assets and business, the
non-compliance with which would have a Material Adverse Effect, and has obtained
all material government licenses, permits and authorizations necessary for the
ownership of its properties and the conduct of its business as currently
conducted, the lack of which would have a Material Adverse Effect.

         4.8. ENVIRONMENTAL MATTERS. With respect to the Transferred Antibody
Collection Business and the Assets, the Seller is in compliance with all
applicable existing federal, state and local laws and regulations relating to
protection of the environmental or imposing liability or standards of conduct

in accordance with U.S. generally accepted accounting principles consistently
applied. Each Center's volume information for fiscal years 1999 and 2000 as set

                        ACTIONS PRIOR TO THE CLOSING DATE

         The parties covenant and agree to take the following actions between
the date hereof and the Closing Date:

         6.1. ACCESS TO INFORMATION. The Seller shall afford to the officers,
employees and authorized representatives of the Buyer (including, without
limitation, independent public accountants, financial advisors and attorneys)
reasonable access during normal business hours, upon reasonable advance notice,
to the offices, properties, employees and business and financial records

   15

reasonably deem necessary or desirable and shall furnish to the Buyer or its

Transferred Antibody Collection Business and the Assets as shall be reasonably
requested; provided, however, that the Seller shall not be required to violate
any obligation of confidentiality to which the Seller is subject in discharging
its obligations pursuant to this Section 6.1. The Buyer agrees that such

breach of any representation or warranty contained in this Agreement, or any
circumstance or condition that upon Closing would constitute such a breach, the
Buyer covenants that it will promptly so inform the Seller.

         6.2. NOTIFICATIONS. The Buyer, on the one hand, and the Seller, on the
other hand, shall promptly notify the other of any action, suit or proceeding

having the purpose or effect of monopolization or restraint of trade. Each party
warrants that all such filings by it will be, as of the date filed, true and

with such request. The Buyer will advise the Seller promptly in respect of any
understandings, undertaking or agreements (oral or written) which the Buyer

manage the transition of the Transferred Antibody Collection Business from the
Seller to the Buyer. The Joint Transition Team shall discuss and agree upon
operational matters that should be addressed prior to Closing, and the parties
at their respective costs shall reasonably cooperate to address such operational
matters. The Joint Transition Team shall also discuss and make recommendations

delivered by the parties at Closing. The Transition Services and the Shared
Services shall be provided by one party to the other party "at cost", which
shall be further clarified and defined in the Transition Services Agreement and
the Shared Services Agreement. The Joint Transition Team shall not have the
final authority to conclude the terms of the Transition Services Agreement or
the Shared Services Agreement; such authority is reserved to the parties. In the
event that the parties for whatever reason fail to negotiate and mutually agree
upon the terms of the Transition Services Agreement at the time of Closing, the
provisions of Schedule 6.6 shall apply and shall have the effect of a binding
legal commitment between the parties on the terms thereof with respect to the

Services are also provided as Transition Services) until such time as a binding
Transition Services Agreement is executed and delivered between the parties.

provide immediate medical and dental coverage to the extent presently provided

such employees' dependents. Notwithstanding the foregoing, nothing in this
Agreement will (a) create any obligation on the part of the Buyer to continue
the employment of any employee for any definite period following the Closing
Date or (b) preclude Buyer from altering, amending or terminating any of its
employee benefit plans or the participation of any of its employees in these

Collection Business and the Buyer shall have the right to use the information

in connection therewith, and (ii) retain such records for not less than three
years from the Closing Date (in the event that the Seller determines to discard
or destroy any such records, the Seller shall first provide notice to the Buyer
who shall have the right to require that such records be transferred to the
Buyer at the Buyer's cost). Any information obtained by the Buyer pursuant to
this Section 7.3(b) which is not related to the Transferred Antibody Collection

which the parties shall execute and deliver at the Closing. In the event that

terms of the Plasma Supply Agreement at the time of Closing, the provisions of
Schedule 7.6 shall apply and shall have the effect of a binding legal commitment
between the parties on the terms thereof until such time as a binding Plasma
Supply Agreement is executed and delivered between the parties.

         7.7. ACCESS TO CERTAIN DONORS. Nothing contained in this Agreement
shall preclude the Seller from soliciting and accepting collections from those
donors listed on Schedule 7.7 attached hereto. Alternatively, the Buyer shall
use commercially reasonable efforts to draw plasma and/or whole blood from such
donors for the Seller at the Seller's request assuming the participation of such
donors, which shall be supplied to the Seller pursuant to the terms of the
Plasma Supply Agreement.

Centers covered by the Offer Terms upon the Offer Terms. The Seller shall
promptly provide such due diligence information as is customary or reasonably
requested by the Buyer, subject to reasonable confidentiality limitations,
during such thirty (30) day period to enable the Buyer to evaluate the Offer
Terms. If the Buyer elects not to purchase all of the Retained Centers offered
to the Buyer on the Offer Terms or does not give notice of acceptance of the
Offer Terms to the Seller during such thirty (30) day period, the Seller shall
be free to sell, transfer and convey the Retained Centers covered by the Offer
Terms on the Offer Terms provided that a binding agreement with respect to such
sale, transfer or

together with the Transition Services, the Shared Services and the rights and
services provided to the Buyer pursuant to the provisions of the Exhibits hereto

clause 10.1(a)(i) with respect to Sections 4.4, 4.5, 4.6, 4.8, 4.9, 4.12, 4.13,
4.15 and 4.16 shall not exceed fifty percent (50%) of the Purchase Price.

                  (b) The indemnification provided for in Section 10.1(a)(i)
shall terminate eighteen (18) months after the Closing Date (and no claims shall
be made by the Buyer under Section 10.1(a)(i) thereafter), except that the
indemnification by the Seller shall continue as to any Losses of which the Buyer
has notified the Seller in accordance with the requirements of Section 10.3 on
or prior to the date such indemnification would otherwise terminate in
accordance with this Section 10.1, as to which the obligation of the Seller
shall continue until the liability of the Seller shall have been determined
pursuant to this ARTICLE 10, and the Seller shall have reimbursed the Buyer for
the full amount of such Losses in accordance with this ARTICLE 10.

         10.2. INDEMNIFICATION BY THE BUYER.

                  (a) The Buyer agrees to indemnify and hold harmless the Seller
from and against any and all Losses incurred by the Seller in connection with or
arising from (i) any breach of any warranty or the inaccuracy of any
representation of the Buyer contained or referred to in this Agreement or in any
certificate delivered by or on behalf of the Buyer pursuant hereto, (ii) any
breach by the Buyer of, or failure by the Buyer to perform, any of its covenants
and obligations contained in this Agreement or (iii) the operations of the
Transferred Antibody Collection Business following the Closing Date including,
without limitation, the use of the Seller's permits and licenses as provided in
Section 1.4, the Buyer's failure to pay, discharge and perform the Assumed
Obligations as provided in Section 2.1, the use of names as provided in Section
7.1 and the proper performance by the Seller of the arrangements referred to in
Section 1.3(a).

                  (b) The indemnification provided for in Section 10.2(a)(i)
shall terminate eighteen (18) months after the Closing Date (and no claims shall
be made by the Seller under Section 10.2(a)(i) thereafter), except that the
indemnification by the Buyer shall continue as to any Losses of which the Seller
has notified the Buyer in accordance with the requirements of Section 10.3 on or
prior to the date such indemnification would otherwise terminate in



                                       23
   25

accordance with this Section 10.2 as to which the obligation of the Buyer shall
continue until the liability of the Buyer shall have been determined pursuant to
this ARTICLE 10, and the Buyer shall have reimbursed the Seller for the full
amount of such Losses in accordance with this ARTICLE 10.

         10.3. NOTICE OF CLAIMS.

                  (a) Any party (the "Indemnified Party") seeking
indemnification hereunder shall give promptly to the party obligated to provide
indemnification to such Indemnified Party (the "Indemnitor") a written notice (a
"Claim Notice") describing in reasonable detail the facts giving rise to the
claim for indemnification hereunder and shall include in such Claim Notice (if
then known) the amount or the method of computation of the amount of such claim,
and a reference to the provision of this Agreement or any other agreement,
document or instrument executed hereunder or in connection herewith upon which
such claim is based. The failure of any Indemnified Party to give the Claim
Notice promptly as required by this Section 10.3 shall not affect such
Indemnified Party's rights under this ARTICLE 10 except to the extent such
failure is actually prejudicial to the rights and obligations of the Indemnitor.

                  (b) In calculating any Loss, there shall be deducted any
insurance recovery in respect thereof (and no right of subrogation shall accrue
hereunder to any insurer). Any indemnity payment hereunder with respect to any
Loss shall be calculated on an "After-Tax Basis", which shall mean an amount
which is sufficient to compensate the Indemnified Party for the event giving
rise to such Loss (the "Indemnified Event"), determined after taking into
account (1) all increases in federal, state, local or other taxes (including
estimated taxes) payable by the Indemnified Party as a result of the receipt of
the indemnity payment (as a result of the indemnity payment being included in
income, resulting in a reduction of tax basis, or otherwise); provided, however,
that the Buyer and the Seller agree to report each payment made in respect of a
Loss as an adjustment to the Purchase Price for federal income tax purposes, (2)
all increases in federal, state, local and other taxes (including estimated
taxes) payable by the Indemnified Party for all affected taxable years as a
result of the Indemnified Event, and (3) all reductions in federal, state, local
and foreign taxes (including estimated taxes) payable by the Indemnified Party
as a result of the Indemnified Event. All calculations shall be made using
reasonable assumptions agreed upon by the Buyer and the Seller and, in the case
of any present value calculations, shall be made using the applicable federal
rate in effect at the time of the Indemnified Event (based on the Federal
mid-term rate) using semi-annual compounding plus two percentage points.

                  (c) After the giving of any Claim Notice pursuant hereto, the
amount of indemnification to which an Indemnified Party shall be entitled under
this ARTICLE 10 shall be determined: (i) by the written agreement between the
Indemnified Party and the Indemnitor; (ii) by a final judgment or decree of any
court of competent jurisdiction; or (iii) by any other means to which the
Indemnified Party and the Indemnitor shall agree. The judgment or decree of a
court shall be deemed final when the time for appeal, if any, shall have expired
and no appeal shall have been taken or when all appeals taken shall have been
finally determined.

         10.4. THIRD PERSON CLAIMS.

                  (a) In order for a party to be entitled to any indemnification
provided for under this Agreement in respect of, arising out of or involving a
claim or demand made by any third party against the Indemnified Party, such
Indemnified Party must promptly notify the Indemnitor in writing, and in
reasonable detail, of the third party claim after receipt by such Indemnified
Party of written notice of the third party claim, but the failure to so notify
the Indemnitor shall not relieve it of any liability it may have to the
Indemnified Party except to the extent such failure is actually prejudicial to
the rights and obligations of the Indemnitor. Thereafter, the Indemnified Party
shall deliver to the Indemnitor copies of all notices and documents (including
court papers) received by the Indemnified Party relating to the third party
claim. Notwithstanding the foregoing, should a party be physically served with a
complaint with regard to a third party claim, the Indemnified Party must notify
the Indemnitor with a copy of the complaint after receipt thereof and shall
deliver to the Indemnitor after the receipt of such complaint copies of notices
and documents (including court papers) received by the Indemnified Party
relating to the third party claim.

                  (b) In the event of the initiation of any legal proceeding
against the Indemnified Party by a third party, the Indemnitor shall have the
sole and absolute right after the receipt of notice, at its option and at its
own expense, to be represented by counsel of its choice and to control, defend
against, negotiate, settle or otherwise deal with any proceeding, claim, or
demand which relates to any loss, liability or damage indemnified against
hereunder; provided, however, that the Indemnified Party may participate in any
such proceeding with counsel of its choice and at its expense. The parties
hereto agree to cooperate fully with each other in connection with the defense,
negotiation or settlement of any such legal proceeding, claim or demand. To the
extent the Indemnitor elects not to defend such proceeding, claim or demand, and
the Indemnified Party defends against or otherwise deals with any such
proceeding, claim or demand, the Indemnified Party may retain counsel, at the
expense of the Indemnitor, and control the defense of such proceeding. Without
the consent of the other party, such consent not to be unreasonably withheld if
the settlement only requires the payment of money, neither the Indemnitor nor
the Indemnified Party may settle any such proceeding which settlement obligates
the other party to pay money, to perform obligations or to admit liability.
After any final judgment or award shall have been rendered by a court,
arbitration board or administrative agency of competent jurisdiction and the
time in which to appeal therefrom has expired, or a settlement shall have been
consummated, or the Indemnified Party and the Indemnitor shall arrive at a
mutually binding agreement with respect to each separate matter alleged to be
indemnified by the Indemnitor hereunder, the Indemnified Party shall forward to
the Indemnitor notice of any sums due and owing by it with respect to such
matter and the Indemnitor shall pay all of the sums so owing to the Indemnified
Party by wire transfer, certified or bank cashier's check within 30 days after
the date of such notice.

         10.5. LIMITATIONS.

                  (a) In any case where an Indemnified Party recovers from third
parties any amount in respect of a matter with respect to which an Indemnitor
has indemnified it pursuant




                                       25
   27

to this ARTICLE 10, such Indemnified Party shall promptly pay over to the
Indemnitor the amount so recovered (after deducting therefrom the full amount of
the expenses incurred by it in procuring such recovery), but not in excess of
the sum of (i) any amount previously so paid by the Indemnitor to or on behalf
of the Indemnified Party in respect of such matter and (ii) any amount expended
by the Indemnitor in pursuing or defending any claim arising out of such matter.

                  (b) Except for remedies that cannot be waived as a matter of
law and injunctive and provisional relief, if the Closing occurs, this ARTICLE
10 shall be the exclusive remedy for breaches of this Agreement (including any
covenant, obligation, representation or warranty contained in this Agreement or
in any certificate delivered pursuant to this Agreement) or otherwise in respect
of the transactions contemplated hereby.

         10.6. MITIGATION. Each of the parties agree to take all reasonable
steps to mitigate their respective Losses upon and after becoming aware of any
event or condition which could reasonably be expected to give rise to any Losses
that are indemnifiable hereunder.

                                   ARTICLE 11
                                   TERMINATION

         11.1. TERMINATION. Anything contained in this Agreement to the contrary
notwithstanding, this Agreement may be terminated at any time prior to the
Closing Date:

                  (a) by the mutual consent of the Buyer and the Seller;

                  (b) by the Buyer in the event of any material breach by the
Seller of any of the Seller's agreements, representations or warranties
contained herein and the failure of the Seller to cure such breach within 30
days after receipt of notice from the Buyer requesting such breach to be cured;

                  (c) by the Seller in the event of any material breach by the
Buyer of any of the Buyer's agreements, representations or warranties contained
herein and the failure of the Buyer to cure such breach within 30 days after
receipt of notice from the Seller requesting such breach to be cured;

                  (d) by the Buyer or the Seller if any court of competent
jurisdiction shall have issued a final and non-appealable order, decree or
ruling permanently restraining, enjoining or otherwise prohibiting the
consummation of the transactions contemplated hereby; or

                  (e) by the Buyer or the Seller, if the Closing shall not have
occurred on or before October 30th, 2001 (or such later date as may be agreed to
in writing by the Buyer and the Seller); provided, however, that if the Closing
shall not have occurred because the waiting period under the HSR Act shall not
have expired or been terminated, either party may extend the October 30th, 2001
date to up to November 30th, 2001; and provided, further, that if the




                                       26
   28

cause of delay of the Closing is due in whole or in substantial part to the
default of a party, such party in default shall not have the right to terminate
this Agreement pursuant to this clause (e).

         11.2. NOTICE OF TERMINATION. Any party desiring to terminate this
Agreement pursuant to Section 11.1 shall give written notice of such termination
to the other parties to this Agreement.

         11.3. EFFECT OF TERMINATION. In the event that this Agreement shall be
terminated pursuant to this ARTICLE 11, all further obligations of the parties
under this Agreement (other than Sections 12.2 and 12.10) shall be terminated
without further liability of either party to the other; provided, that, nothing
herein shall relieve any party from liability for its willful breach of this
Agreement.

                                   ARTICLE 12
                               GENERAL PROVISIONS

         12.1. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties contained in this Agreement shall survive the consummation of the
transactions contemplated by this Agreement through the period during which
claims for indemnification in respect thereof may be made pursuant to ARTICLE 10
(at which time all representations and warranties shall terminate).

         12.2. CONFIDENTIAL NATURE OF INFORMATION. Each party hereto agrees that
all documents, materials and other information which it shall have obtained
regarding the other parties during the course of the negotiations leading to the
consummation of the transactions contemplated hereby (whether obtained before or
after the date of this Agreement), the investigation provided for herein and the
preparations of this Agreement and other related documents shall be held in
confidence pursuant to the letter agreement between the parties dated April 4,
2001 (the "Confidentiality Agreement"), provided that from and after the Closing
the Buyer may use and disclose such documents, materials and other information
in its sole discretion (unless such documents, materials and other information
otherwise prohibit such use and disclosure).

         12.3. NO PUBLIC ANNOUNCEMENT. Neither the Buyer, on the one hand, nor
the Seller, on the other hand, shall, without the approval of the other, make
any press release or other public announcement concerning the transactions
contemplated by this Agreement, except as and to the extent that any such party
shall be so obligated by law, in which case the other party shall be advised and
the parties shall use their best efforts to cause a mutually agreeable release
or announcement to be issued; provided, however, that the foregoing shall not
preclude communications or disclosures necessary to implement the provisions of
this Agreement or to comply with the accounting and disclosure obligations of
the Securities and Exchange Commission or the rules of any stock exchange or
Nasdaq or to enable the Buyer to obtain debt or equity financing.

                  (a) The rights of either party under this Agreement shall not
be assignable by such party hereto prior to the Closing without the written
consent of the other party, provided that the Buyer may assign this Agreement or
its rights hereunder to one or more subsidiaries of the Buyer without the
consent of the Seller. No such assignment shall relieve the Buyer from any
obligation or liability under this Agreement.

                  (b) This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their successors and permitted assigns.
Nothing in this Agreement, expressed or implied, is intended or shall be
construed to confer upon any person, other than the parties and successors and
assigns permitted by this Section 12.5 any right, remedy or claim under or by
reason of this Agreement.

         12.6. ENTIRE AGREEMENT; AMENDMENTS. This Agreement and the Exhibits and
Schedules referred to herein and the documents delivered pursuant hereto and the
Confidentiality Agreement contain the entire understanding of the parties hereto
with regard to the subject matter contained herein or therein, and supersede all
other prior agreements, understandings or letters of intent between or among any
of the parties hereto. This Agreement shall not be amended, modified or
supplemented except by a written instrument signed by an authorized
representative of each of the parties hereto.

         12.7. INTERPRETATION.

                  (a) Articles, title and headings to sections herein are
inserted for convenience of reference only and are not intended to be a part of
or to affect the meaning or interpretation of this Agreement. The Schedules
referred to herein shall be construed with and as an integral part of this
Agreement to the same extent as if they were set forth verbatim herein.
Disclosure of any fact or item in any Schedule hereto referenced by a particular
section in this Agreement shall be deemed to have been disclosed with respect to
every other section in this Agreement. Neither the specification of any dollar
amount in any representation or warranty contained in this Agreement nor the
inclusion of any specific item in any Schedule hereto is intended to imply that
such amount, or higher or lower amounts, or the item so included or other items,
are or are not material, and no party shall use the fact of the setting forth of
any such amount or the inclusion of any such item in any dispute or controversy
between the parties as to whether any obligation, item or matter not described
herein or included in any Schedule is or is not material for purposes of this
Agreement. Unless this Agreement specifically provides otherwise, neither the
specification of any item or matter in any representation or warranty contained
in this Agreement nor the inclusion of any specific item in any Schedule hereto
is intended to imply that such item or matter, or other items or matters, are or
are not in the ordinary course of business, and no party shall use the fact of
the setting forth or the inclusion of any such item or matter in any dispute or
controversy between the parties as to whether any obligation, item or matter not
described herein or included in any Schedule is or is not in the ordinary course
of business for purposes of this Agreement.

                  (b) The parties acknowledge and agree that: (i) each party and
its counsel reviewed and negotiated the terms and provisions of this Agreement
and has contributed to its revision; (ii) the rule of construction to the effect
that any ambiguities are resolved against the drafting party shall not be
employed in the interpretation of this Agreement; and (iii) the terms and
provisions of this Agreement shall be construed fairly as to all parties hereto
and not in favor of or against any party, regardless of which party was
generally responsible for the preparation of this Agreement.

         12.8. "SELLER'S KNOWLEDGE" DEFINED. For purposes of this Agreement,
"Seller's knowledge" means, as to a particular matter, (a) the actual knowledge
of the following persons: Chief Executive Officer; Executive Vice President and
Chief Operating Officer; Chief Financial Officer; Senior Vice President,
Manufacturing Operations; and General Counsel and (b) that knowledge that would
be obtained or for which a reason to believe would ordinarily develop upon
customary (within the industry) and reasonably prudent inquiry into or analysis
of the matter at hand.

         12.9. WAIVERS. Any term or provision of this Agreement may be waived,
or the time for its performance may be extended, by the party or parties
entitled to the benefit thereof. Any such waiver shall be validly and
sufficiently authorized for the purposes of this Agreement if, as to any party,
it is authorized in writing by an authorized representative of such party. The
failure of any party hereto to enforce at any time any provision of this
Agreement shall not be construed to be a waiver of such provision, nor in any
way to affect the validity of this Agreement or any part hereto or the right of
any party thereafter to enforce each and every such provision. No waiver of any
breach of this Agreement shall be held to constitute a waiver of any other or
subsequent breach.

         12.10. EXPENSES; TAXES.

performed or complied with, including the fees, expenses and disbursements of
its counsel and independent public accountants.

                  (b) The Buyer shall pay all sales and other taxes imposed by
any governmental entity in connection with the transfer of the Assets, excluding
any taxes on or measured by the Seller's net income.

         12.11. CURRENCY. All dollar amounts set forth in this Agreement are
expressed in currency of the United States of America, and all payments to be
made pursuant to this Agreement shall be made in United States of America
dollars.

         12.12. PARTIAL INVALIDITY. Wherever possible, each provision hereof
shall interpreted in such manner as to be effective and valid under applicable
law, but in case any one or more of the provisions contained herein shall, for
any reason, be held to be invalid, illegal or unenforceable in any respect, such
provision shall be ineffective to the extent, but




                                       30
   32

only to the extent, of such invalidity, illegality or unenforceability without
invalidating the remainder of such invalid, illegal or unenforceable provision
or provisions or any other provision hereof, unless such a construction would be
unreasonable.

         12.13. EXECUTION IN COUNTERPARTS. This Agreement may be executed in one
or more counterparts, each of which shall be considered an original instrument,
but all of which shall be considered one and the same agreement, and shall
become binding when one or more counterparts have been signed by each of the
parties hereto and delivered to the Seller and the Buyer.

         12.14. GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the internal laws (as opposed to the conflicts of law
provisions) of the State of Delaware.

         12.15. DISCLAIMER OF WARRANTIES. The Seller makes no representations or
warranties with respect to any projections, forecasts or forward-looking
information provided to the Buyer. There is no assurance that any projected or
forecasted results will be achieved. EXCEPT AS TO THOSE MATTERS EXPRESSLY
COVERED BY THE REPRESENTATIONS AND WARRANTIES IN THIS AGREEMENT AND THE
CERTIFICATE DELIVERED BY THE SELLER PURSUANT TO SECTION 8.1, THE SELLER IS
SELLING THE ASSETS ON AN "AS IS, WHERE IS" BASIS AND THE SELLER DISCLAIMS ALL
OTHER WARRANTIES, REPRESENTATIONS AND GUARANTIES, WHETHER EXPRESS OR IMPLIED AND
THE SELLER MAKES NO REPRESENTATION OR WARRANTY AS TO MERCHANTABILITY OR FITNESS
FOR ANY PARTICULAR PURPOSE AND NO IMPLIED WARRANTIES WHATSOEVER. The Buyer
acknowledges that neither the Seller nor any of its representatives nor any
other person has made any representation or warranty, express or implied, as to
the accuracy or completeness of any memoranda, charts, summaries or schedules
heretofore made available by the Seller or its representatives to the Buyer or
any other information which is not included in this Agreement or the Schedules
hereto, and neither the Seller nor any of its representatives nor any other
person will have or be subject to any liability to the Buyer or any other person
resulting from the distribution of any such information to, or use of any such
information by, the Buyer or any of its agents, consultants, accountants,
counsel or other representatives.

                               FIRST AMENDMENT TO
                    AGREEMENT FOR PURCHASE AND SALE OF ASSETS

         This Amendment is entered into as of September 6, 2001 (the "Closing
Date") by Nabi, a Delaware corporation ("Seller"), and ZLB Bioplasma Inc., a
Delaware corporation ("Buyer").

                                   BACKGROUND

A. Seller and CSL Limited, an Australian Capital Territory corporation ("CSL"),
are parties to an Agreement for Purchase and Sale of Assets dated June 25, 2001
(the "Purchase Agreement"). CSL has assigned its rights and obligations under
the Purchase Agreement to Buyer. Capitalized terms used in this Addendum without
definition shall have the meaning assigned in the Purchase Agreement. All
references to the Purchase Agreement in any document executed by the parties
shall mean the Purchase Agreement as amended by this Amendment.

B. The parties desire to amend the Purchase Agreement in the manner described in
this Amendment.

         In consideration of the foregoing and the mutual promises and covenants
contained herein, the parties amend the Purchase Agreement as follows:

1.       DMS SUBLICENSE. All references in the Purchase Agreement to the DMS
         Sublicense are deleted.

2.       REVISED SCHEDULES. The Schedules to the Purchase Agreement are hereby
         amended as set forth in Exhibit A hereto.

3.       LICENSES AND PERMITS. The licenses and permits listed on Exhibit B
         hereto cannot lawfully be transferred by Seller to Buyer. As provided
         in Section 1.4 of the Purchase Agreement, Seller shall allow Buyer to
         operate under such licenses and permits for a period of 180 days
         following the Closing Date and shall not cancel any such license or
         permit or any bonds, guarantees or undertakings of Seller in connection
         therewith until expiration of such 180 day period.

4.       (Reserved)

5.       LEASE ASSIGNMENTS. The consents of the respective lessors ("Landlords")
         to the assignment of the Leases listed in Exhibit D have not been
         obtained as of the Closing Date. Buyer and Seller shall execute a
         mutually acceptable Management Agreement under which Buyer will be
         engaged to manage the business conducted at the Plasma Centers
         represented by those Leases until the required Landlord consents are
         obtained.



   2

         Upon receipt of the applicable Landlord consent to the assignment of
         each such Lease, Seller and Buyer will terminate the Management
         Agreement with respect to that Plasma Center and will execute an
         Assignment and Assumption of Lease with respect to that Lease in the
         form executed by the parties on the Closing Date. The effective date of
         each such assignment shall be the date on which the applicable
         Landlord's consent is obtained. With respect to each such Lease, (a)
         Seller shall perform all financial obligations and retain all
         liabilities under the Lease prior to receipt of the Landlord's consent,
         but (b) in no event shall Seller be liable to Buyer with respect to any
         claim for breach under any such Lease by virtue of the Management
         Agreement or Buyer's operation of any Plasma Center pursuant thereto.

6.       BILL OF SALE. The Bill of Sale contemplated in Section 3.6(a) of the
         Purchase Agreement shall not include an assumption of liabilities.

7.       PURCHASE PRICE ALLOCATION. The parties shall agree to an allocation of
         the Purchase Price pursuant to Section 3.7 of the Purchase Agreement as
         soon as possible following the Closing Date.

8.       AGENT'S LETTER. Notwithstanding the provisions of Section 4.4 of the
         Purchase Agreement and Schedules 4.4(a) and 4.4(b) thereto, the
         mortgages encumbering the Owned Properties and held by Bank of America,
         N.A. ("Bank of America") and the liens encumbering other Assets held by
         Bank of America shall be released in accordance with Bank of America's
         written undertaking to that effect dated August 28, 2001 ("Agent's
         Letter"). Seller shall perform all covenants on its part recited in the
         Agent's Letter.

9.       NOTICE. For purposes of Section 12.4 of the Purchase Agreement, notice
         to Buyer shall be given to:

                                    ZLB Bioplasma Inc.
                                    801 N. Brand Avenue

                                    Attn: Peter de Hart, President

         with copies to the persons identified in the Purchase Agreement.

10.      NONCOMPETE AGREEMENTS. To the extent any employees of Seller who become
         employed by Buyer after the Closing Date are parties to a noncompete
         agreement with Seller, Seller agrees that it will not enforce the
         non-competition provision of any such agreement arising solely from the
         employee's employment by Buyer or any of its affiliates.

11.      SUBSTITUTE ATTACHMENTS. The Substitute Attachments to Appendix A to the
         Purchase Agreement circulated between and initialed by the parties on
