                                Explanatory Note

         This Amendment No. 1 to the Annual Report on Form 10-KSB/A (this
"Amendment") amends the Annual Report on Form 10-KSB for the year ended December
31, 2003 filed on March 30, 2004 (the "Original Filing"). Bay National
Corporation has filed this Amendment to add additional disclosure to Item 9 of
the Original Filing. Pursuant to Rule 12b-15 under the Securities Exchange Act
of 1934, as amended, the complete text of Items 9 as amended is set forth below.
The remainder of the Form 10-KSB is unchanged and is not reproduced in this
Amendment. The certifications required by Section 302 of the Sarbanes-Oxley Act
are also included with this Amendment.

         This Amendment speaks as of the original filing date of the Form 10-KSB
and reflects only the changes described above. No other information included in
the Original Filing, including the consolidated financial statements and the
footnotes thereto, has been modified or updated in any way.

         This Amendment should be read together with other documents that Bay
National Corporation has filed with the Securities and Exchange Commission
subsequent to the filing of the Original Filing. Information in such reports and
documents updates and supersedes certain information contained in this
Amendment. The filing of this Amendment shall not be deemed an admission that
our Original Filing, when made, included any known, untrue statement of material
fact or knowingly omitted to state a material fact necessary to make a statement
not misleading.

Item 12.  Certain Relationships and Related Transactions

         Prior to Bay National Corporation's initial public offering, the
organizers of Bay National Corporation and Bay National Bank and certain other
investors purchased an aggregate of 112,500 shares of Bay National Corporation's
common stock at a purchase price of $10.00 per share. The primary purpose of
this "organizational offering" was to provide Bay National Corporation and Bay
National Bank with the capital necessary to fund some of the initial
organizational and prepaid operating expenses.

         In recognition of the financial and organizational risk undertaken by
the purchasers in the organizational offering, on September 10, 1999, the
purchasers in the organizational offering received, for no additional
consideration, a warrant to purchase one share of common stock at $10.00 per
share for every two shares that they purchased in the organizational offering.
As a result, Bay National Corporation issued warrants to purchase an aggregate
of 56,250 shares of common stock to the purchasers in the organizational
offering.

         The warrants became exercisable on April 30, 2001 and are exercisable
in whole or in part until November 16, 2004. The warrants and the shares of
common stock issuable upon the exercise of the warrants are transferable subject
to compliance with applicable securities laws. Among other requirements, if the
OCC issues a capital directive or other order requiring Bay National Bank to
obtain additional capital, the warrants are forfeited if not immediately
exercised.

         Lucy Mohler, the spouse of Hugh W. Mohler, serves as Bay National
Corporation's and Bay National Bank's Vice President of Marketing and Investor
Relations. Ms. Mohler earned an aggregate compensation of $64,371 plus benefits
valued at $2,932 during 2003 from Bay National Bank.

         Director John R. Lerch owns a 100% interest in the property being
leased for Bay National Bank's Salisbury, Maryland branch office. Pursuant to
that lease, which is for a five-year term and commenced as of September 1, 1999,
Bay National Corporation agreed to pay Mr. Lerch monthly rent of approximately
$1,980 plus all real estate taxes and utilities. Bay National Corporation
believes that the lease rate, at the time of entering into the lease, was at
fair market value, based, in part, on an evaluation of the lease terms by
William E. Martin of ERA Martin Associates, a Salisbury-based real estate
brokerage firm. Bay National Corporation engaged Mr. Martin to review the lease
terms for the purpose of determining whether the terms were consistent with the
lease terms for similar properties in the downtown Salisbury area.

         Director Gary T. Gill is president and chief executive officer of the
MacKenzie Companies, which owns the property being leased for Bay National
Bank's Lutherville, Maryland corporate and branch offices. Bay National
Corporation is a party to two leases for this property. Pursuant to the first
lease, which is for a five year and five month term and commenced on July 26,
1999, Bay National Corporation agreed to pay monthly rent of approximately
$1,900, which amount increases at the rate of four percent per year. The monthly
rent as of December 31, 2003 was $2,223. Pursuant to the second lease, which is
for a five year term and commenced on March 1, 2000, Bay National Corporation
agreed to pay monthly rent of approximately $10,773, which amount increases at
the rate of four percent per year. The monthly rent as of December 31, 2003 was
$12,118. The monthly rent under both leases includes Bay National Corporation's
share of taxes and building operating costs. Both leases were entered into well
in advance of Mr. Gill's appointment to the Board of Directors in January 2003.
Bay National Corporation believes that the lease rates, at the time of entering
into the lease, were at fair market value,

         Some of Bay National Bank's directors and officers and the business and
professional organizations with which they are associated have banking
transactions with Bay National Bank in the ordinary course of business. It is
Bay National Bank's policy that any loans and loan

commitments will be made in accordance with applicable laws and on substantially
the same terms, including interest rates and collateral, as those prevailing at
the time for comparable transactions with other persons of comparable credit
standing. Loans to directors and officers must comply with Bay National Bank's
lending policies and statutory lending limits, and directors with a personal
interest in any loan application will be excluded from considering any such loan
application.

         The officers and directors of Bay National Corporation and Bay National
Bank have loans due to Bay National Bank of $4,672,104 at December 31, 2003. All
loans were made on substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable transactions with
unaffiliated third parties and do not involve more than the normal risk of
repayment or present other unfavorable features.
