SECOND AMENDMENT TO LEASE

THIS SECOND AMENDMENT TO LEASE (this "Second Amendment") is made effective as of
June 11, 2008, by and between VON KARMAN MICHELSON CORPORATION, a Delaware
corporation ("Landlord"), and CALIFORNIA FIRST NATIONAL BANCORP, a California
corporation ("Tenant"), with reference to the following:

A.       World Trade Center Building, Inc., a Japanese corporation and
Landlord's predecessor-in-interest under the Lease, as herein defined ("Original
Landlord"), and Tenant entered into that certain Office Building Lease dated as
of January 30, 2003 (the "Original Lease"), as amended by that certain Amendment
to Lease dated as of December 17, 2004 (the "First Amendment"), by and between
Landlord and Tenant (the Original Lease, as amended by the First Amendment, is
hereinafter referred to as the "Lease"), for the lease of certain premises (the
"Existing Premises") known collectively as Suites 400 ("Suite 400"), 420, 700
and 800 consisting in the aggregate of approximately 48,568 rentable square feet
in that certain building (the "Building") located at 18201 Von Karman Avenue,
Irvine, California 92612, as more particularly described in the Lease.

B.        Landlord and Tenant desire by this Second Amendment to amend the Lease
in order to (i) extend the Term, (ii) provide for a revised Monthly Base Rent,
(iii) reduce the Existing Premises by approximately 5,197 rentable square feet
consisting of Suite 400 (for such purposes, the "Surrendered Space"), and (iv)
further amend, modify and supplement the Lease as set forth herein.

NOW, THEREFORE, in consideration of the foregoing Recitals (which are
incorporated herein by this reference), for the mutual promises contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree
as follows:

1.         Definitions. Capitalized terms used herein and not otherwise defined
herein shall have the meanings ascribed to such terms in the Lease. Unless the
context clearly indicates otherwise, all references to the "Lease" in the Lease
and in this Second Amendment shall hereinafter be deemed to refer to the Lease,
as amended hereby.

2.         Extension of Term. Landlord and Tenant acknowledge that the Term is
scheduled to expire on August 31, 2008. Notwithstanding anything to the contrary
contained in the Lease, in accordance with Section 40 of the Original Lease,
Landlord and Tenant agree that the Term is hereby extended for a period of sixty
(60) complete calendar months (the "Extension Term") commencing on September 1,
2008 (the "Extension Term Commencement Date") and ending on August 31, 2013,
unless sooner terminated in accordance with the terms of the Lease. In addition,
any reference in the Lease to the "Term" or words of similar import shall mean
the Term together with the Extension Term, unless the context clearly indicates
otherwise, and any reference in the Lease to the "Expiration Date" or words of
similar import shall mean August 31, 2013, unless the context clearly indicates
otherwise.

3.         Reduction of Existing Premises. Notwithstanding anything to the
contrary contained in the Lease, Tenant shall, on the day immediately prior to
the Extension Term Commencement Date (the "Return Date"), vacate, surrender and
return exclusive possession of the Surrendered Space to Landlord in the
condition required under, and otherwise in accordance with the terms and
conditions of, the Lease, and Tenant and all of Tenant's subtenants, assignees
and other transferees, if any, shall have no further right to the Surrendered
Space. Without limitation as to the foregoing, Tenant shall continue to lease
the remaining 43,371 rentable square feet of the Existing Premises known as
Suites 420, 700 and 800 (the "Reduced Premises"), upon and subject to all of the
terms and conditions of the Lease (Landlord and Tenant hereby acknowledge and
agree that such stated amount of the rentable square footage of the Reduced
Premises is not a representation or warranty of the exact number of rentable
square feet therein but rather is only a reasonable approximation and that the
rent is not subject to revision whether or not the actual square footage is more
or less than such approximation). Accordingly, effective on the Extension Term
Commencement Date, (a) all references to the "Premises" in the Lease shall mean
and refer to the Reduced Premises, and (b) "Tenant's Percentage" shall mean and
refer to 19.7430% (subject to increase or decrease in the event Landlord, in
accordance with sound property management practices, determines that the
rentable square footage of the Building is more or less than the rentable square
footage of the Building as stated in the Lease). As soon as reasonably
practicable after the Return Date, Landlord shall, at its sole cost and expense
and using Building-standard materials and methods, separate Suite 420 from the
Surrendered Space by removing the glass doors in the common wall between such
suites and filling in the opening in the common wall created by such removal
(the "Demising Work"). Tenant hereby acknowledges that Landlord will be
performing the Demising Work during the Term (as extended by the Extension
Term), and Tenant shall not be entitled to any abatement or reduction of Rent in
connection with the Demising Work or to any change in the Extension Term
Commencement Date, nor shall the Demising Work be deemed an eviction, actual or
constructive, of Tenant. Tenant shall at all times cooperate reasonably and in
good faith in connection with Landlord's prosecution of the Demising Work,
including, without limitation, by granting Landlord access to any portion of the
Premises and by promptly responding to matters arising in connection with the
Demising Work. Without limitation as to the foregoing, Landlord shall exercise
commercially reasonable efforts to minimize interference with Tenant's business
operations during Landlord's prosecution of the Demising Work. In the event
Tenant fails to vacate, surrender and return exclusive possession of the
Surrendered Space to Landlord in the condition required under, and otherwise in
accordance with the terms and conditions of, the Lease on the Return Date, then,
in addition to all other rights and remedies Landlord may have pursuant to the
Lease and at law and in equity, Tenant shall be deemed a holdover tenant and the
terms and conditions of Section 11(b) of the Original Lease shall apply with
respect to the Surrendered Space.

4.         Monthly Base Rent for Extension Term. Notwithstanding anything to the
contrary contained in the Lease, and in addition to all other amounts due and
payable by Tenant in connection with the Lease to be paid in the manner
specified therein, including, without limitation, Additional Rent, Tenant shall,
commencing on the Extension Term Commencement Date, pay in the manner specified
in the Lease, Monthly Base Rent for the Reduced Premises as follows:

2

--------------------------------------------------------------------------------

 

Months Monthly Base Rent Per Rentable Square Feet Monthly Base Rent 1 - 12 $2.85
$123,607.35 13 - 24 $2.95 $127,944.45 14 - 36 $3.05 $132,281.55 37 - 48 $3.15
$136,618.65 49 - 60 $3.25 $140,955.75

Provided that Tenant has faithfully performed all of the terms and conditions of
the Lease, Landlord agrees to abate (a) all Monthly Base Rent and parking
charges for the first seven (7) months of the Extension Term, and (b) fifty
percent (50%) of Tenant's obligation to pay Monthly Base Rent for months eight
(8) through forty-six (46), inclusive, of the Extension Term ("Conditional
Rent"). Notwithstanding the foregoing, however, during such months, Tenant shall
still be responsible for the payment of Additional Rent. The right to the
abatement set forth above shall be personal to California First National
Bancorp, a California corporation ("Named Tenant") and shall not be transferable
to any assignee, sub-tenant or other transferee of Named Tenant's interest in
the Lease.

5.         Base Year. Notwithstanding anything to the contrary contained in the
Lease, effective on the Extension Term Commencement Date, the "Base Year" (as
defined in the Lease) shall mean calendar year 2009.

6.         Parking. The terms and conditions of the Lease applicable to parking
shall continue in full force and effect during the Extension Term (including,
without limitation, the parking rate of $25.00 per unreserved and reserved
parking space per month) except that, notwithstanding anything to the contrary
contained in the Lease, Section 7 of the First Amendment shall, effective as of
the Extension Term Commencement Date, be deemed null and void and of no further
force or effect.

7.         5th Floor Expansion Option. In addition to Tenant's right to
additional space on the sixth (6th) floor of the Building under Section 41 of
the Original Lease, Tenant's shall have the right to lease all or any portion of
that certain space (the "5th Floor Space") consisting of approximately 7,000
rentable square feet constituting Suites 520 and 550 currently available for
lease on the fifth (5th) floor of the Building (such right, for purposes of this
Section 7, shall be referred to as the "5th Floor Space Expansion Right"),
subject to the terms and provisions of the Lease, including, without limitation,
Section 42 of the Original Lease (which is hereby made applicable to the 5th
Floor Space Expansion Right); provided, that (a) the 5th Floor Space Expansion
Right shall be exercisable by Tenant with respect to all or any portion of the
5th Floor Space by written notice to Landlord given at any time on or prior to
the close of business on August 29, 2008 ("5th Floor Notice"), (b) the term of
the lease by Tenant of all or any portion of the 5th Floor Space that Tenant
elects to take pursuant to a 5th Floor Notice shall commence on or before
September 1, 2008 and shall terminate in accordance with the terms of the Lease
(as amended hereby), (c) the remaining terms of the lease by Tenant of all or
any portion of the 5th Floor Space shall be on all of the terms and provisions
set forth in the Lease (as amended hereby), but at the Rent rate in effect for
the Premises at the commencement of Tenant's lease of the applicable 5th Floor
Space, but such 5th Floor Space shall be tendered by Landlord and leased by
Tenant in its as-is condition without improvements or improvement allowance,

3

--------------------------------------------------------------------------------

 

and (d) in the event that such 5th Floor Notice is not delivered by Tenant with

purposes of inducing Landlord to enter into this Second Amendment; and (iii)
Landlord is relying on such representations in entering into this Second

38(j) of the Original Lease.

agreement and understanding between the parties concerning the subject matter of
this Second Amendment and supersedes all prior agreements, terms,
understandings, conditions, representations and warranties, whether written or
oral, concerning the matters that are the subject of this Second Amendment.
