Item 1.01 Entry into a Material Definitive Agreement

Indemnification Agreements with Directors and Executive Officers

Tekelec (the “Company”) has entered into or expects to enter into, effective as of September 12, 2011, a new form of indemnification agreement with each of its current directors and executive officers (each an “Indemnitee”).

Each indemnification agreement provides, among other terms, that (i) the Company will indemnify the Indemnitee, subject to certain conditions, against any and all indemnifiable amounts (including, among other amounts, expenses, damages, judgments, fines, penalties and amounts paid in settlement) arising out of or resulting from any threatened, pending or completed legal action or proceeding, whether initiated by a third party or by or in the right of the Company, arising out of or relating to the Indemnitee’s service as a director, officer, employee or other agent of the Company or any other corporation or other enterprise for which such person serves at the Company’s request, (ii) the Company will advance expenses to the Indemnitee in advance of the settlement of or final judgment in any such action or proceeding, (iii) the Indemnitee will repay such advanced expenses only if a court shall ultimately determine that the Indemnitee is not entitled to be indemnified by the Company and (iv) the indemnification provided by the indemnification agreement is not exclusive of any other rights to which the Indemnitee may be entitled under the Company’s Amended and Restated Articles of Incorporation, Amended and Restated Bylaws, any agreement, any vote of shareholders or disinterested directors, the California General Corporation Law or otherwise. The indemnification agreement also sets forth the terms and conditions that apply in determining whether or not an Indemnitee is entitled to indemnification in any given instance.

The Company’s directors and executive officers who have entered into or are expected to enter into such indemnification agreements effective as of September 12, 2011 are listed below:
