Item 29. Indemnification

(a) Brief description of indemnification provisions:

In general, Article VII of the By-Laws of The Lincoln National Life Insurance Company (Lincoln Life) provides that Lincoln Life will indemnify certain persons against expenses, judgments and certain other specified costs incurred by any such person if he/she is made a party or is threatened to be made a party to a suit or proceeding because he/she was a director, officer, or employee of Lincoln Life, as long as he/she acted in

good faith and in a manner he/she reasonably believed to be in the best interests of, or not opposed to the best interests of, Lincoln Life. Certain additional conditions apply to indemnification in criminal proceedings.

In particular, separate conditions govern indemnification of directors, officers, and employees of Lincoln Life in connection with suits by, or in the right of, Lincoln Life.

Please refer to Article VII of the By-Laws of Lincoln Life (Exhibit No. 6(b) hereto) for the full text of the indemnification provisions. Indemnification is permitted by, and is subject to the requirements of, Indiana law.

(b) Undertaking pursuant to Rule 484 of Regulation C under the Securities Act of 1933:

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 28(a) above or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any such action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
