2 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.

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

(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

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.

(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).

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. 24

26 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. 27

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.

Brand Avenue Suite 1150 Glendale, California 91203 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 the date hereof are accepted by Seller and Buyer. 2
