(b) In the case of any other property, the “Fair Market Value” means the value of such property, assuming an arm’s-length transaction between a willing buyer and seller, capable of being sold free of restriction in a liquid market without giving effect to any discounts (for minority interests), taking into account any other factors that the Persons making such determination reasonably believe should be taken into account, and, if such property includes Common Stock, assuming carrying on of Nasdaq as a going concern. Absent agreement by the applicable parties as to the “Fair Market Value” within 20 days after the date such distribution is declared by the Board of Directors, the applicable parties shall each designate, within 10 days after such 20-day period, an Investment Bank to determine the Fair Market Value.

If the difference between the higher and the lower of the respective final views of the two Investment Banks is equal to or greater than 10% of the higher of the respective final views, the applicable parties shall instruct the Investment Banks jointly to designate a third Investment Bank who shall be an Independent Investment Bank (the “Mutually Designated Appraiser”).

The Fair Market Value as designated by the Mutually Designated Appraiser, shall be final and binding on the parties, and may be entered and enforced in any court having jurisdiction. Each party shall bear the fees and expenses of its Investment Bank. Fees and expenses of the Mutually Designated Appraiser shall be borne equally by the applicable parties. Notwithstanding the foregoing, in the event that one of the applicable parties does not appoint an Investment Bank within the time periods specified above, such party shall have waived its rights to appoint an Investment Bank and the determination of the Fair Market Value shall be made solely by the Investment Banks of the party who did appoint an Investment Bank. Each of the parties (on its own behalf and on behalf of its respective Affiliates) shall cooperate with each of the Investment Banks and the Mutually Designated Appraiser to provide such information as may reasonably be requested. In addition, if the property being valued includes Investor AB Shares, Investor AB shall use commercially reasonable efforts to cause Investor AB to provide to each of the Investment Banks and the Mutually Designated Appraiser reasonable access to management of Investor AB and to the books and records of Investor AB so as to allow each of them to conduct due diligence examinations in scope and duration as are customary in valuations of this kind.

Designee and who shall be reasonably acceptable to the Nominating Committee (or an successor committee serving such function) (the “Investor AB Committee Designee”) to a committee of the Board reasonably agreed to by Investor AB and the Company (the “Committee”), in each of the foregoing subject to applicable law, regulation, stock exchange listing standard or committee composition standards.

Section 3.2 No Interference with Board Rights. Nasdaq will use its reasonable best efforts not to, directly or indirectly, propose or take any action to encourage any modification to the composition of the Board of Directors, in Nasdaq’s reasonable judgment, would likely result in the elimination or significant diminishment of the rights of Investor AB specified in Section 3.1; provided that the foregoing shall in no way limit Nasdaq’s right to increase the number of directors on the Board of Directors.

ARTICLE IV

VOTING RIGHTS

Section 7.10 Recapitalization, Etc. In case of any consolidation, merger, reorganization, reclassification, sale, conveyance, consolidation, spin-off, partial or complete liquidation, stock dividend, transfer or lease in which Nasdaq is not the surviving person, then (a) all rights and obligations of Nasdaq under this Nasdaq Stockholders’ Agreement shall be assumed by and transferred to any such successor person, with the same effect as if it had been named herein as the party of this first part and (b) all references in this Nasdaq Stockholders’ Agreement to “Nasdaq” shall be deemed to refer to such person; provided, however, in any case, Nasdaq will not effect any such transaction unless the successor delivers to Investor AB an agreement in writing in a form reasonably satisfactory to Investor AB agreeing to be bound by the terms of this Nasdaq Stockholders’ Agreement. The intent of the Parties is to fairly and equitably preserve the original rights and obligations of the Parties hereto under this Nasdaq Stockholders’ Agreement.

Section 7.12 Specific Performance. The Parties hereby acknowledge and agree that the failure of any Party to perform its agreements and covenants hereunder, including its failure to take all actions as are necessary on its part to the consummation of the transactions contemplated hereby, will cause irreparable injury to the other Parties, for which damages, even if available, will not be an adequate remedy. Accordingly, each Party hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of such Party’s obligations, to prevent breaches of this Nasdaq Stockholders’ Agreement by such Party and to the granting by any court of the remedy of specific performance of such Party’s obligations hereunder, without bond or other security being required, in addition to any other remedy to which any Party is entitled at law or in equity.

The Parties hereto agree that if any of the provisions of this Nasdaq Stockholders’ Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine, and that the Parties shall be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or equity.

Common Stock on a Fully-Diluted Basis

Methodology:

•

The Common Stock price (the “Common Stock Price”) to be used in each calculation herein shall be the volume-weighted average price on the last trading day immediately prior to the measuring date (the “Measuring Date”).

•

The number of outstanding shares of Common Stock shall be the actual shares outstanding (not weighted) at the Measuring Date, plus the Nasdaq Shares.

•

The number of unvested shares of restricted stock shall be calculated using the treasury stock method of computing the dilutive impact at the Common Stock Price based the unvested shares of restricted stock outstanding on the Measuring Date.

•

The number of shares of Common Stock underlying options shall be calculated using the treasury stock method of computing the dilutive impact at the Common Stock Price, including all options outstanding but exercisable on the Measuring Date, with no weighting and no forfeitures.

•

The number of shares of Common Stock underlying convertible debt shall be calculated using the if converted method at the Common Stock Price.

•

The number of shares underlying warrants shall be calculated using the treasury stock method at the Common Stock Price.

Sample Calculation:


Shares of Common Stock outstanding			113,234,706
Unvested restricted stock			155,157
Shares underlying options			5,536,023
Shares underlying convertible debt			30,689,655
Shares underlying warrants			2,759,308
Total shares outstanding			152,374,849
