ARTICLE I.
Definitions

Capitalized terms used but not defined in this Agreement are used in this Agreement with the meanings given to such terms in the Merger Agreement.  In addition, for purposes of this Agreement:

“Affiliate” means, with respect to any specified person, a person who, at the time of determination, directly or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, such specified person.  For purposes of this Agreement, with respect to Stockholder, “Affiliate” does not include ANI and the persons that directly, or indirectly through one or more intermediaries, are controlled by ANI.  For the avoidance of doubt, no officer or director of ANI will be deemed an Affiliate of another officer or director of ANI by virtue of his or her status as an officer or director of ANI.

“Beneficially Owned” or “Beneficial Ownership” with respect to any securities means having beneficial ownership of such securities (as determined pursuant to Rule 13d-3 under the Exchange Act, disregarding the phrase “within 60 days” in paragraph (d)(1)(i) thereof), including pursuant to any agreement, arrangement or understanding, whether or not in writing.  Without duplicative counting of the same securities, securities Beneficially Owned by a person include securities Beneficially Owned by (i) all Affiliates of such person, and (ii) all other persons with

whom such person would constitute a “group” within the meaning of Section 13(d) of the Exchange Act and the rules promulgated thereunder.

“Beneficial Owner” with respect to any securities means a person that has Beneficial Ownership of such securities.

“person” has the meaning ascribed thereto in the Merger Agreement.

“Subject Shares” means, with respect to Stockholder, without duplication, (i) the ANI Shares owned by Stockholder on the date hereof as described on Schedule A, and (ii) any additional ANI Shares acquired by Stockholder or over which Stockholder acquires Beneficial Ownership from and after the date hereof, whether pursuant to existing stock option agreements, warrants or otherwise.  Without limiting the other provisions of this Agreement, in the event that ANI changes the number of ANI Shares issued and outstanding prior to the Expiration Date as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, combination, recapitalization, subdivision, or other similar transaction, the number of Subject Shares subject to this Agreement will be equitably adjusted to reflect such change.

“Transfer” means, with respect to a security, the sale, transfer, pledge, hypothecation, encumbrance, assignment or disposition of such security or the Beneficial Ownership thereof, and each option, agreement, arrangement or understanding, whether or not in writing, to effect any of the foregoing.  As a verb, “Transfer” has a correlative meaning.

ARTICLE II.
Covenants of Stockholder

2.1                                 Irrevocable Proxy.  Concurrently with the execution of this Agreement, Stockholder agrees to deliver to the Company a proxy in the form attached hereto as Exhibit A (the “Proxy”), which will be irrevocable to the extent provided in Section 212 of the Delaware General Corporation Law (the “DGCL”), with respect to the Subject Shares referred to therein.

2.3                                 Revocation of Proxies; Cooperation.  Stockholder agrees as follows:

(a)                                  Stockholder hereby represents and warrants that any proxies heretofore given in respect of the Subject Shares with respect to the matters described in Section 2.2(a) hereof are not irrevocable, and Stockholder hereby revokes any and all prior proxies with respect to such Subject Shares as they relate to such matters.  Prior to the Expiration Date, Stockholder will not directly or indirectly grant any proxies or powers of attorney with respect to the matters set forth in Section 2.2(a) hereof (other than to the Company), deposit any of the Subject Shares or enter into a voting agreement (other than this Agreement) with respect to any of the Subject Shares relating to any matter described in Section 2.2(a).

(b)                                 Unless required by Applicable Law or permitted by the Merger Agreement, Stockholder will not, and will not authorize or direct any of its Affiliates or Representatives to, make any press release or public announcement with respect to this Agreement or the Merger Agreement or the transactions contemplated hereby or thereby, without the prior written consent of the Company in each instance.

8

Stockholder could not be adequately compensated by monetary damages.  Accordingly, Stockholder agrees that, (a) it will waive, in any action for specific performance, the defense of adequacy of a remedy at law, and (b) in addition to any other right or remedy to which the Company may be entitled, at law or in equity, the Company will be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

6.10                           Waiver.  The rights and remedies of the parties to this Agreement are cumulative and not alternative.  Neither any failure nor any delay by a party in exercising any right, power or privilege under this Agreement, the Proxy or any of the documents referred to in this Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any other right, power or privilege.  To the maximum extent permitted by Applicable Law, (a) no claim or right arising out of this Agreement, the Proxy or any of the documents referred to in this Agreement can be discharged by one party, in whole or in part, by a waiver or renunciation of the claim or right unless in a written document signed by the other party, (b) no waiver that may be given by a party will be applicable except in the specific instance for which it is given, and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of that party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement, the Proxy or the documents referred to in this Agreement.
