    LAKESIDE STATE BANK, an Oklahoma banking corporation, Appellant, v. The BANKING BOARD OF the STATE OF OKLAHOMA; R.Y. Empie Oklahoma Banking Commissioner, 1st Bank of Catoosa, Catoosa, Oklahoma, Appellee.
    No. 61368.
    Supreme Court of Oklahoma.
    June 12, 1984.
    
      Phillip McGowan, Sanders & Carpenter, Tulsa, for appellant.
    J. Schaad Titus, Boone, Smith, Davis & Hurst, Tulsa, for appellee First Bank of Catoosa.
   KAUGER, Justice.

The sole issue presented is whether the statute controlling issuance of branch banking certificates, 6 O.S.1983 Supp. § 501(B)(3) precludes establishment of a branch bank in a town located within twenty-five miles of the main bank if the Oklahoma Banking Board has previously issued a certificate for a branch bank to a competitor. We find that § 501(B)(3) does not operate to make the two applications mutually exclusive. The granting of a certificate of authority to 1st Bank of Catoosa, Catoosa, Oklahoma to open a branch bank in Verdigris, Oklahoma is affirmed.

On September 15, 1983, appellant, Lakeside State Bank of Oologah, Oklahoma (Lakeside), applied to the Oklahoma Banking Board (Board) for authority to open and maintain a branch bank in the town of Verdigris, Oklahoma, pursuant to 6 O.S. 1983 Supp. § 501(B)(3). An application for branch banking in Verdigris was filed by the 1st Bank of Catoosa, Catoosa, Oklahoma, (Catoosa) on September 28, 1983. The applications were set for hearing before the Board on October 26, 1983. The application of Lakeside was heard first and granted. When Catoosa’s application was heard later that day, Lakeside protested issuance of a certificate to Catoosa to operate its branch bank. Nevertheless, the Board granted a certificate to Catoosa to operate a branch bank in Verdigris. Lakeside appealed.

DOES A BRANCH BANK FALL WITHIN THE PURVIEW OF PROHIBITION AS ESTABLISHED BY THE STATUTE CONTROLLING ISSUANCE OF BRANCH BANKING CERTIFICATES: 6 O.S.1983 Supp. § 501(B)(3)?

Lakeside contends that the Board’s granting of authority allowing it to open a branch bank prevents the Board from granting branch banking privileges to any other bank. Lakeside relies upon the very statute under which its branch banking authority was awarded to argue that the Board has no authority to allow Catoosa to operate a branch bank. To support this contention, Lakeside argues that under its branch banking authority it performs banking functions which meet the statutory definition of a “bank”; and that because its branch bank is a bank located in the city of Verdigris under 6 O.S.1983 Supp. § 501(B)(3) no other branch bank can be authorized.

This argument must fail. A reading of our banking law shows clearly that the term main bank means the primogeniture bank, and the specific location designated by the Commissioner or Comptroller of Currency as a main office. While it is true that a branch bank may perform any banking function, its location can never be the same as that of the main office. This designation of location establishes the bank as a main bank for purposes of § 501(B)(3) and branch banking. The procedure for creation of a primary bank is contained in 6 O.S.1982 Supp. § 301. These requirements are separate and distinct from those permitting the establishment of a branch bank. The grant of authority to operate a branch bank under § 501(B)(3) cannot be substituted for an original certificate of authority to engage in banking. While the everyday business of a branch bank may be the same as its main bank, the branch bank cannot meet the statutory requisites governing creation of a bank. A branch bank is not a “bank” under the description contained in § 501(B)(3).

The Board found expressly among other pertinent findings, that: the site of the proposed bank was located within twenty-five miles of Catoosa’s main office; a state or national bank was not located in Verdigris; and that because Catoosa had met all the statutory criteria, it should be granted a branch banking certificate. The expertise of an administrative agency is accorded great weight, and a presumption of validity attaches to the exercise of expertise on review. A review of the evidence contained in Catoosa’s application reflects that the Board’s findings of fact and conclusions of law are based upon reliable, material, probative and substantial competent evidence — the issuance of the certificate should be affirmed.

AFFIRMED.

All Justices concur.
