1.The Lincoln National Life Insurance Company (the “Company”) is duly organized and existing under the laws of the State of Indiana and has been duly authorized to do business and to issue annuity contracts by the State of Indiana and the Indiana Department of Insurance.

2.The contracts covered by the above registration statement, and all post-effective amendments relating thereto, when delivered and when the first purchase payment made by an owner all in accordance with the prospectus included in the registration statement and in compliance with the applicable local law, will be a legal and binding obligation of the Company in accordance with its terms. Owners of contracts, as such, will not be subject to any deductions and charges by the Company other than those described in the contract and as referred to in the applicable prospectus.

I consent to the filing of this Opinion as an exhibit to Pre-Effective Amendment No. 1 to the Registration Statement on Form S-3.

Sincerely,
