Re:      Nationwide Life Insurance Company
         Nationwide VLI Separate Account-4
         Pre-Effective Amendment to Initial Filing
         File No. 333-53728

Ladies and Gentlemen:

I have acted as Counsel to Nationwide Life Insurance Company (the "Company"), an
Ohio insurance company, and its Nationwide VLI Separate Account-4 (the "Separate
Account") in connection with the registration of an indefinite number of
securities in the form of variable life insurance policies (the "Policies") with
the Securities and Exchange Commission under the Securities Act of 1933, as
amended. I have examined the registration statement on Form S-6, including all
related documents and exhibits, and reviewed such questions of law as I
considered necessary and appropriate. On the basis of such examination and
review, it is my opinion that:

1.   The Company is a corporation duly organized and validly existing as a stock
     life insurance company under the laws of the State of Ohio and is duly
     authorized to issue and sell life insurance and annuity contracts.

2.   The Separate Account has been properly created and is a validly existing
     separate account pursuant to the laws of the State of Ohio.

3.   The issuance and sale of the Flexible Premium Variable Universal Life
     Insurance Policies have been duly authorized by the Company. The Policies,
     when issued and sold in the manner stated in the registration statement,
     will be legal and binding obligations of the Company in accordance with
     their terms, except that clearance must be obtained, or the policy form
     must be approved, prior to the issuance thereof in certain jurisdictions.

4.   To the extent so provided under the Policies, that portion of the assets
     of the Separate Account equal to the reserves and other policy liabilities
     with respect to the Separate Account, will not be chargeable with
     liabilities arising out of any other business that the Company may conduct.

I hereby consent to the filing of this opinion as an exhibit to the Registration
Statement filed on Form S-6 for the Policies and the Separate Account.

Very truly yours,


Heather Harker
Variable Products Securities Counsel
