Exhibit 10.3.1

FIRST AMENDMENT TO SERVICE AGREEMENT

This First Amendment to Service Agreement (this “Amendment”), dated as of
July 10, 2009 (the “Effective Date”), is made by and between Parkway Properties
LP, a Delaware limited partnership (“Service Provider”), and Xenith Corporation,
a Virginia corporation formerly known as Xenith Bank [In Organization]
(“Customer”).

RECITALS:

By Service Agreement dated as of September 26, 2008 (the “Service Agreement”)
between Service Provider and Customer, Service Provider leased to Customer
certain office space known as Suite 410, 1011 Boulder Springs Drive, Richmond,
Virginia, and more particularly described in the Service Agreement, on the terms
set forth in the Service Agreement.

Service Provider and Customer now wish to modify the Service Agreement in the
manner set forth below.

FIRST AMENDMENT TO SERVICE AGREEMENT:

NOW, THEREFORE, for and in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, Service Provider and Customer agree as follows:

1. Modification. Sections 55(d) and 56 of the Service Agreement are hereby
deleted in their entirety and the following are substituted in lieu thereof:

“55. Funding of Improvement Costs Allowance.

. . . .

“(d) Reimbursement to Customer. Provided that no monetary Default has occurred
under this Service Agreement through the date on which the reimbursement that is
the subject of this paragraph is to be made, and subject to the occurrence of
each of the following conditions, within thirty (30) days after (i) Customer’s
occupancy of the entire Premises for the purpose of conducting business in the
Premises; (ii) the Commencement Date; and (iii) Service Provider’s receipt from
Customer of evidence of the Governmental Approvals (as hereinafter defined),
whichever occurs last, Service Provider shall reimburse Customer for the cost of
the Initial Improvements in an amount equal to the lesser of (x) the Improvement
Costs Allowance; (y) the Improvement Costs; or (z) any portion of the
Improvement Costs Deposit not previously refunded to Customer as provided in
Section 55(c) above.

“56. Termination Option. Customer is currently using, and agrees to continue to
use, commercially reasonable efforts to acquire voting control of First
Bankshares, Inc., a Virginia bank holding company (“FBS”), which owns all of the
outstanding capital stock of SuffolkFirst Bank, a Virginia banking corporation
(the “Bank”), pursuant

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

to a Merger Agreement dated as of May 12, 2009 (the “Merger Agreement”) between
Customer and FBS. Upon closing of the merger described in the Merger Agreement
(the “Merger”), the combined companies will operate as a one-bank holding
company under the name Xenith Bankshares, Inc. (“Xenith Bankshares”), the Bank
will change its name to Xenith Bank and Customer will cause the Bank to assume
in writing all of the rights and obligations of Customer under this Service
Agreement. The Merger has been approved by the boards of directors of Customer
and FBS, and closing of the Merger is subject to, among other customary
conditions, (i) issuance by the State Corporation Commission of Virginia of a
certificate of merger, (ii) approval of the Merger by the Board of Governors of
the Federal Reserve System under the Federal Bank Holding Company Act, and
(iii) approval of the Merger by the Virginia Bureau of Financial Institutions
under Virginia Code §6.1-383.1 governing the acquisition of Virginia bank
holding companies (collectively the “Governmental Approvals”). If (and only if)
Customer is unable, after using commercially reasonable efforts, to obtain the
Governmental Approvals and close the Merger on or before November 30, 2009, time
being of the essence (the “Approval Deadline”), Customer shall have the option
(the “Termination Option”) to terminate this Service Agreement and the term and
estate hereby granted by giving Service Provider the Termination Notice (as
hereinafter defined), and by paying the Termination Fee (as hereinafter defined)
no later than the Approval Deadline, time being of the essence. If Customer
shall timely exercise the Termination Option, this Service Agreement shall
terminate effective as of the Termination Date, defined below. Upon receiving
all Governmental Approvals, Customer shall provide evidence of the Governmental
Approvals to Service Provider.

“(a) Grant of Termination Option. Subject to the foregoing provisions of this
Section 56, Customer is hereby granted the Termination Option as stated above.
If Customer elects to exercise the Termination Option, Customer must do so in
strict compliance with the terms and conditions set forth herein.

“(b) Exercise of Termination Option. In order to exercise the Termination
Option, Customer must timely deliver the “Termination Notice,” and timely pay
the “Termination Fee,” to Service Provider as provided below:

“(i) Termination Notice. If Customer elects to exercise the Termination Option,
as provided above, then Customer shall do so by delivering written notice of
such election to Service Provider, in compliance with the Notices provision of
this Service Agreement (the notice exercising the Termination Option being
referred to herein as a “Termination Notice”), no later than the Approval
Deadline. The effective date of such termination (the “Termination Date”) shall
be the earlier of (i) fifteen (15) days after the date upon which Customer is
advised in writing it will not receive all of the Governmental Approvals, or
(ii) December 10, 2009. In the event that any of the Governmental Approvals is
or would be denied to Customer, Customer shall provide documentation to Service
Provider demonstrating to Service Provider’s reasonable satisfaction that such
Governmental Approval has been or would be denied contemporaneously with
Customer’s delivery of the Termination Notice. If Customer does not, for
whatever reason, forward such Termination Notice to Service Provider by the
Approval Deadline, then Customer’s right to exercise the Termination Option
shall expire.

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

“(ii) Termination Fee. In the event that Customer elects to exercise the
Termination Option, Customer shall pay to Service Provider a fee (the
“Termination Fee”) to be calculated and paid in accordance with the terms of
this paragraph. The Termination Fee shall be paid by Customer to Service
Provider contemporaneously with Customer’s delivery to Service Provider of the
Termination Notice, and shall consist of the entire amount of the Improvement
Costs Allowance, less any portion of the Improvement Costs Deposit paid by
Customer to Service Provider under Section 55(b) above, for which no
reimbursement to Customer has been made by Service Provider under Section 55(d)
above as of the date on which the Termination Notice is delivered to Service
Provider, plus the Generator Costs incurred by Service Provider as of such date.
The parties acknowledge and agree that the Termination Fee does not constitute a
penalty, but rather is the parties’ reasonable pre-estimate of a portion of
Service Provider’s probable loss in the event that Customer elects to exercise
the Termination Option. Customer shall not be entitled to a refund of any
portion of the Termination Fee, regardless of whether Service Provider leases
all or any portion of the Premises to a third party, at any time after receipt
of the Termination Notice.

“If Customer fails to deliver the Termination Notice or the Termination Fee to
Service Provider within the time permitted hereby, or if Customer does not
effectively exercise the Termination Option in accordance with the terms hereof,
or if all the terms and conditions set forth above for the exercise of the
Termination Option are not entirely satisfied, then (a) this Service Agreement
shall continue beyond the Termination Date, and Customer shall continue to be
bound by the terms of this Service Agreement as if the Termination Option had
not been exercised; and (b) the Termination Fee, or portion thereof, paid by
Customer, if any, shall be returned to Customer (unless an event of Default then
exists under this Service Agreement, in which case Service Provider may apply
the Termination Fee, or portion thereof, paid by Customer toward the amount then
due under this Service Agreement and return the balance, if any, to Customer).

“(c) Effect of Exercise of Termination Option. If Customer exercises the
Termination Option in accordance with the terms hereof: (a) Customer shall be
fully liable for the payment to Service Provider of all Rent and other charges
owed under this Service Agreement which shall become due through and including
the Termination Date, and for the prompt and complete performance of all terms
and conditions of this Service Agreement, through and including the Termination
Date; (b) Customer shall surrender the Premises to Service Provider in
accordance with the terms of this Service Agreement no later than the
Termination Date; (c) if Customer shall remain in possession of the Premises
beyond the Termination Date, then Customer shall be a tenant holding over as
provided in this Service Agreement; and (d) all obligations of the parties which
would survive the expiration of this Service Agreement shall also survive the
early termination of this Service Agreement.

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

“(d) Termination Option Personal to Customer. The Termination Option is not
transferable. The parties hereto acknowledge and agree that they intend that the
Termination Option shall be “personal” to Customer, and that in no event shall
any assignee or subtenant of Customer have any right to exercise the Termination
Option set forth herein, notwithstanding any prior approval by Service Provider
of the assignment of this Service Agreement or the subletting of the Premises.”

2. Ratification. Except as expressly modified hereby, the terms and provisions
of this Service Agreement are hereby ratified and confirmed and remain in full
force and effect. In the event of any inconsistency between the provisions of
this Service Agreement and the provisions of this Amendment, the provisions of
this Amendment shall govern and control.

3. Execution in Counterparts. To facilitate execution, the parties hereto may
execute this Amendment in counterparts. All counterparts of this Amendment shall
be deemed to constitute a single agreement. Counterparts of this Amendment, when
executed, may be delivered by facsimile or electronic mail transmission and
shall have the same force and effect as if such counterparts bore the original
signature of the party or parties thereto.

IN WITNESS WHEREOF, this First Amendment to Service Agreement is executed, and
all provisions shall be effective, as of the Effective Date.
