Ladies and Gentlemen:

I am Vice President, Chief Corporate Counsel and Corporate Secretary of Berkshire Hathaway Energy Company, as appointed counsel for MidAmerican Energy Company, an Iowa corporation (the “Company”). I have served in such capacity in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-3 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration under the Securities Act and the proposed issuance and sale from time to time pursuant to Rule 415 under the Securities Act, together or separately and in one or more series (if applicable) of the Company’s: (i) unsecured debt securities, which may either be senior debt securities (the “Senior Debt Securities”) or subordinated debt securities (the “Subordinated Debt Securities”), (ii) first mortgage bonds (the “First Mortgage Bonds” and, collectively with the Senior Debt Securities and the Subordinated Debt Securities, the “Debt Securities”), (iii) shares of the Company’s preferred stock, no par value (the “Preferred Stock”), and (iv) depositary shares each representing a fraction of a share of a particular series of Preferred Stock (the “Depositary Shares”).

The Senior Debt Securities are to be issued under an indenture (the “Senior Base Indenture”), to be entered into between the Company and The Bank of New York Mellon Trust Company, N.A. (the “Trust Company”), as indenture trustee. The Subordinated Debt Securities are to be issued under an indenture (the “Subordinated Base Indenture”) to be entered into between the Company and the Trust Company, as indenture trustee. The First Mortgage Bonds are to be issued under the Indenture, dated as of September 9, 2013, between the Company and the Trust Company, as indenture trustee, as supplemented and amended by the First Supplemental Indenture, dated as of September 19, 2013, between the Company and the Trust Company, as indenture trustee (as so supplemented and amended, the “Mortgage Bond Indenture,” and collectively with the Senior Base Indenture and the Subordinated Base Indenture, the “Base Indentures”). The Company has also executed a Mortgage, Security Agreement, Fixture Filing and Financing Statement, dated as of September 9, 2013 (the “Mortgage”), in favor of the Trust Company, in its capacity as collateral trustee (the “Collateral Trustee”), and an intercreditor and collateral trust agreement, dated as of September 9, 2013 (the “Collateral Trust Agreement” and, together with the Mortgage, the “Security Documents”), with the Trust Company, in its capacity as indenture trustee, and the Trust Company, in its capacity as the Collateral Trustee.
