Item 4.01 Changes in Registrant's Certifying Accountant.

(a) On March 17, 2005, as approved by the Audit Committee, Farmers & Merchants
Bancorp appointed the accounting firm of Perry-Smith LLP as independent
accountants for the Registrant for the first quarter of 2005 and for the year
2005. PricewaterhouseCoopers LLP was dismissed on March 17, 2005.

The following is the information required by Regulation S-K, Item 304(a)(1)
concerning the dismissal of PricewaterhouseCoopers LLP: PricewaterhouseCoopers
LLP was dismissed. PricewaterhouseCoopers LLP's reports on our financial
statements for the past two fiscal years did not contain an adverse opinion or a
disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit
scope, or accounting principles. The decision to dismiss PricewaterhouseCoopers
LLP, was recommended and approved by our Audit Committee. During the two most
recent fiscal years and through March 17, 2005, there were no disagreements with
PricewaterhouseCoopers LLP, on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreements if not resolved to the satisfaction of PricewaterhouseCoopers LLP
would have caused them to make reference thereto in their report on the
financial statements for such years. During the two most recent fiscal years and
through March 17, 2005, there were no "reportable events" as such term is
defined in Item 304(a)(1)(v) of Regulation S-K.

We have provided PricewaterhouseCoopers LLP, a copy of this disclosure, and have
requested that it furnish us with a letter addressed to the Commissioner stating
whether PricewaterhouseCoopers LLP, agrees with the statements made by us in
this disclosure, and, if not, stating the respects in which it does not agree.
PricewaterhouseCoopers LLP's response letter is attached as an exhibit hereto.


(b) As stated above, Perry-Smith LLP was appointed on March 17, 2005, as our
independent public accountants. During our two most recent fiscal years, and
through March 17, 2005, we did not consult with Perry-Smith LLP, on any issue,
nor did Perry-Smith LLP, advise us on any application of accounting principles
to a specified transaction, either completed or proposed, or the type of audit
opinion that might be rendered on our financial statements, or any matter that
was either the subject of a "disagreement" or a "reportable event" (each as
defined in Item 304(a)(1) of Regulation S-K).
