Item 1.01. Entry into a Material Definitive Agreement.

Amendment to Merger Implementation Agreement

On September 17, 2012, Nabi Biopharmaceuticals, a Delaware corporation (“ Nabi ”), and Biota Holdings Limited, a Melbourne, Australia company (“ Biota ”), entered into an amendment deed (the “ Amendment ”) to the merger implementation agreement, dated April 22, 2012 (as previously amended on August 6, 2012, the “ Transaction Agreement ”), between Nabi and Biota.

As previously disclosed, pursuant to the Transaction Agreement, Nabi and Biota propose to undertake a business combination under Australian corporate law such that each ordinary share of Biota capital stock (the “ Biota Shares ”) will be exchanged for newly issued shares of Nabi common stock (the “ New Nabi Shares ”), and Biota will become a wholly-owned subsidiary of Nabi (the “ Transaction ”). Existing shares of Nabi common stock outstanding at the completion of the Transaction will remain outstanding. In connection with the Transaction, Nabi will change its name to “Biota Pharmaceuticals, Inc.” but will remain listed on the NASDAQ Stock Market and headquartered in the U.S. A copy of the Transaction Agreement was included as Exhibit 2.1 to Nabi’s Current Report on Form 8-K filed by Nabi with the U.S. Securities and Exchange Commission (the “ SEC ”) on April 23, 2012. A copy of the amendment dated August 6, 2012 to the Transaction Agreement was included as Exhibit 2.1 to Nabi’s Current Report on Form 8-K filed by Nabi with the SEC on August 8, 2012.

The Amendment modifies the following terms of the Transaction Agreement, among others:

 

   

Nabi cash at closing —Nabi’s assets at the completion of the Transaction will include US$27 million in cash, instead of US$54 million, as originally provided in the Transaction Agreement. Nabi plans to return to its stockholders its remaining cash in excess of the US$27 million required to be held by Nabi at closing after satisfying outstanding liabilities. Such distribution is expected to take the form of a dividend or return of capital, and currently is expected to be in the range of approximately US$28 million to US$31 million in the aggregate.

 

   

Adjustment to exchange ratio —Under the amended terms, the actual number of New Nabi Shares to be issued to Biota stockholders in exchange for Biota Shares, and therefore the actual percentage ownership of the outstanding common stock of the combined company to be held by current Nabi stockholders, will be determined under a collar mechanism based on the volume-weighted average (“ VWAP ”) price of Biota Shares on the Australian Securities Exchange (ASX) during the 10 trading days prior to either the Nabi stockholder meeting or the Biota stockholder meeting, whichever one takes place first (the ten day VWAP), as converted into U.S. dollars. The collar range consists of a ten day VWAP equal to or greater than A$0.62 and equal to or less than A$0.86.

As a way of example, using the collar range described above and assuming that the historical daily exchange rate of the Australian dollar against the U.S. dollar on each corresponding day of the ten day VWAP is US$1.05 to A$1.00, each Biota Share will be transferred to Nabi in exchange for between approximately 0.69403 and approximately 0.96269 New Nabi Shares. As a result, New Nabi Shares issued to former Biota stockholders will represent between approximately 81.5% and 85.9% of the outstanding common stock of the combined company and shares of Nabi common stock held by current Nabi stockholders will represent between approximately 14.1% and 18.5% of the outstanding common stock of the combined company.

 

1


   

Collar mechanism and termination right —If the ten day VWAP is equal to or greater than A$0.62 or equal to or less than A$0.86, the exchange ratio will be based on the actual ten day VWAP.

If the ten day VWAP is less than A$0.62, Nabi may terminate the Transaction Agreement. If Nabi does not exercise its right to terminate the Transaction Agreement, then the exchange ratio will be based on A$0.62.

If the ten day VWAP is greater than A$0.86, Biota may terminate the Transaction Agreement. If Biota does not exercise its right to terminate the Transaction Agreement, then the exchange ratio will be based on A$0.86.

Neither Nabi nor Biota will be required to pay a break fee to the other party for terminating the Transaction Agreement as described above.

 

   

Extension of end date —The date on which the Transaction Agreement will automatically terminate if the Transaction has not been completed has been extended from October 31, 2012 to November 30, 2012.

Nabi intends to file with the SEC and disseminate to its stockholders a supplement (the “ Supplement ”) to Nabi’s definitive proxy statement, dated August 7, 2012, that will describe the amended terms of the Transaction Agreement and provide related relevant information.

A copy of the Amendment is filed as Exhibit 2.1 hereto and is incorporated herein by reference. The description of the Amendment included in this Item 1.01 is not complete and is qualified in its entirety by reference to the full text of the Amendment set forth on Exhibit 2.1 .

Date for Stockholder Voting to be Announced

In order to provide Nabi stockholders with sufficient time and opportunity to consider the amended terms of the Transaction, the meeting of Nabi stockholders to vote on the proposals related to the Transaction, originally scheduled to be held on September 24, 2012, will be either adjourned or postponed to a new date that Nabi will announce. The Transaction and related matters also require the approval of Biota stockholders.

Support of Transaction by Mangrove

Mangrove Partners Fund, L.P. and certain of its affiliates, which own approximately 4% of the outstanding shares of Nabi common stock and had previously opposed the Transaction, have entered into a support agreement dated September 17, 2012 with Nabi pursuant to which Mangrove has agreed to support the Transaction, as amended, and to vote all of the shares of Nabi common stock owned by them in accordance with the recommendation of Nabi’s Board of Directors on each of the proposals set forth in the Nabi definitive proxy materials in connection with the Transaction. The obligations of Mangrove under the support agreement cease in the event the Transaction is further amended on economic terms any less favorable than the terms of the amended Transaction. Under the support agreement, Nabi has agreed to reimburse Mangrove for costs associated with its proxy solicitation of up to an aggregate amount of US$100,000.

A copy of the support agreement is filed as Exhibit 10.1 hereto and is incorporated herein by reference. The description of the support agreement included in this Item 1.01 is not complete and is qualified in its entirety by reference to the full text of the support agreement set forth on Exhibit 10.1 .

Important Additional Information

In connection with the Transaction, Nabi has filed a definitive proxy statement, dated August 7, 2012, with the SEC in connection with a special meeting of stockholders of Nabi to be held on September 24, 2012 and will be filing a Supplement to the definitive proxy statement describing the amended Transaction. STOCKHOLDERS AND INVESTORS ARE URGED TO READ NABI’S DEFINITIVE PROXY MATERIALS, THE SUPPLEMENT AND ANY OTHER RELEVANT SOLICITATION MATERIALS FILED BY NABI WITH THE SEC BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE TRANSACTION. Stockholders and investors may obtain a free copy of Nabi’s definitive proxy statement and other materials filed by Nabi with the SEC at the SEC’s website at www.sec.gov, at Nabi’s website at www.nabi.com, or by contacting Morrow & Co., LLC, Nabi’s proxy solicitation agent, at (203) 658-9400 or toll-free at (800) 607-0088.

Forward-Looking Statements

Statements set forth above that are not strictly historical are forward-looking statements and include statements about the Transaction and related matters, the exchange ratio under the Transaction Agreement, Nabi’s plans to distribute cash or other rights to its stockholders, expected timing and completion of the proposed transactions, cash expenditures, and alliances and partnerships, among other matters. You can identify these forward-looking statements because they involve Nabi’s expectations, intentions, beliefs, plans, projections, anticipations, or other characterizations of future events or circumstances. These forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties that may cause actual results to differ materially from those in the forward-looking statements as a result of any number of factors.

Nabi does not undertake to update any of these forward-looking statements or to announce the results of any revisions to these forward-looking statements except as required by law.

2. Amendment to clause 4.2(a) of the MIA

 

  (a) Clause 4.2(a) of the MIA is deleted and replaced with the following:

“Subject to the Scheme becoming Effective and clauses 4.2(b), 4.2(c) and 4.3, Nabi agrees in favour of Biota that, in consideration for the transfer to Nabi of each Scheme Share under the Scheme, Nabi accepts such transfer, and provides to each Scheme Shareholder such number of New Nabi Shares for each Scheme Share held by them, determined in accordance with paragraph (i) below, provided however that if Nabi completes a reverse stock split prior to the Implementation Date, then the number of New Nabi Shares for each Scheme Share calculated in accordance with paragraph (i) below will be adjusted in accordance with paragraph (ii) below.

 

2


  (i) The number of New Nabi Shares to be issued by Nabi to each Scheme Shareholder for each Scheme Share held by them, is equal to:

 

  

N N x (1 – Cash Ratio)

  
   N B D x Cash Ratio   

where:

N N is the number of Nabi Shares outstanding as at 17 September 2012 (28,328,034) plus 1,187,335 (being one third of the number of Nabi stock options on issue as at 17 September 2012).

N B D is the number of Biota Shares outstanding as at 17 September 2012 calculated on a fully diluted basis, being 187,402,665 (comprising 182,763,561 Biota Shares and 4,639,104 Biota Share Rights which will vest on Court approval of the Scheme).

Cash Ratio is the exchange ratio determined in accordance with the following formula:

 

   Cash Ratio =   

US$ 27 million

  (ii) In the event that Nabi completes a reverse stock split prior to the Implementation Date, then the number of New Nabi Shares for each Scheme Share calculated in accordance with paragraph (i) above is adjusted in accordance with the following formula:

 

   NNS    x   

N N – N SC

  
      N N   

where:

NNS is the number of New Nabi Shares calculated in accordance with paragraph (i) above.

N N is the number of Nabi Shares outstanding immediately prior to the reverse stock split.

N SC is the reduction in the number of Nabi Shares outstanding as a result of the reverse stock split.

It is noted that the purpose of this formula is to preserve the respective percentage of shares of Nabi’s issued stock to be held immediately after the Implementation Date by Scheme Shareholders (collectively) on one hand and Nabi Stockholders immediately prior to the Implementation Date (collectively) on the other hand (subject in each case to rounding), so that Nabi Stockholders interest in Nabi immediately after the Implementation Date reflects the Cash Ratio.”

 

3


  (b) The following new clause 4.2(d) is inserted into the MIA:

“The Ten Day VWAP is determined as follows:

 

  (i) the Ten Day VWAP means, subject to paragraphs (ii) and (iii) below, the volume weighted average sale price of Biota Shares on the ASX (excluding (1) a transaction classified under the ASX Market Rules as a “Special Crossing” (as defined in the ASX Market Rules) and (2) a “Crossing” (as defined in the ASX Market Rules) outside the “Open Session State” (as defined in the ASX Market Rules)) during the last ten Trading Days up to and including the Trading Day that is immediately prior to the First Meeting;

 

  (ii) if the Ten Day VWAP determined under paragraph (i) is greater than $0.86, the parties agree that the Ten Day VWAP will be taken to be $0.86; and

“( Nabi Deed Poll )

 

  (i) prior to the First Court Date, execute the Nabi Deed Poll; and

 

  (ii) in the event that the parties agree in writing to amend the Scheme after Nabi has executed the Nabi Deed Poll, execute a further deed poll in favour of the Scheme Shareholders giving effect to that amendment;”

 

4. Amendment to clause 12.2(d)

Clause 12.2(d) of the MIA is amended by deleting that clause and inserting the following new clause 12.2(d):

“For the avoidance of doubt, the Biota Break fee will not be payable merely by reason that (1) the Scheme is not approved by Biota Shareholders at the Scheme Meeting or (2) that Biota has terminated this Agreement in accordance with clause 13.3(c) of this Agreement.”

 

5. Amendment to clause 12.3(d)

Clause 12.3(d) of the MIA is amended by deleting that clause and inserting the following new clause 12.3(d):

4
