Item  1.01  Entry Into Material Definitive Agreement


John Nerland Supplemental Employee Retirement Plan
- --------------------------------------------------


Summary of Principal Terms of Nerland Supplemental Employee Retirement Plan.

On December 12, 2005, John Nerland,  President of Solano Bank, a division of The
Vintage Bank (North Bay Bancorp's wholly-owned subsidiary),  agreed to and enter
into a  Participation  Agreement  under the North Bay Bancorp 2005  Supplemental
Employee  Retirement Plan (the "SERP").  The  participation  agreement is in the
form  previously  filed  with the SERP as  Exhibit  10.2 to North Bay  Bancorp's
Quarterly Report on Form 10-Q for the Quarter ended September 30, 2005.

Under the  participation  agreement,  Mr.  Nerland  will  receive a defined cash
benefit  payable  monthly upon retirement upon reaching age 65 (or upon or after
age 62  with  a  reduced  benefit),  subject  to  the  terms  set  forth  in the
participation agreement agreement. Benefits under the agreement vest over a five
year periods at the rate of 20% per year  beginning  after  September  30, 2007.
Yearly benefits will continue until his death subject to forfeiture in the event
of unfair  competition  with The Vintage Bank prior to commencement of benefits.
The defined cash benefit per year payable to Mr. Nerland, assuming 100% vesting,
is $75,000.  This amount will be  increased  annually at the rate of two percent
(2%) per year from the date of commencement of payments until death.


If Mr.  Nerland elects early  retirement or elects to receive  payments prior to
age 65, he shall receive the greater of the actuarial  equivalent or that amount
calculated as follows:

Benefits  to be  received  shall be  decreased  by a  percentage  calculated  by
subtracting  his age as of the date  payments are to commence  (which  cannot be
earlier than age 62) from 65 and multiplying the result by a factor of five (5).
For example,  a 15%  reduction  of benefits  would occur if the age at which Mr.
Nerland's payments are to commence is 62  (65-62=3x5=15%).  In such case, annual
benefits would be $63,750.
