                     FIRST AMENDMENT TO EMPLOYMENT AGREEMENT

        THIS AMENDMENT TO EMPLOYMENT AGREEMENT ("Amended Agreement") is made and
entered into as of this 31st day of December, 2002, by and between BANK OF
HAMPTON ROADS, INC., a banking corporation organized under the laws of the
Commonwealth of Virginia (the "Bank", or "Employer") and JULIE R. ANDERSON, (the
"Officer").

                                R E C I T A L S :

        1. The Bank and the Officer entered into an Employment Agreement (the
"Agreement") dated the 11th day of October, 2001.

        2. Since entering into the Agreement, the Officer has been employed by
the Bank and both the Bank and the Officer currently wish to continue that
relationship.

        3. The Agreement as originally prepared provided that it would, absent
written notice to the contrary, renew for an additional period of sixty months
from the original anniversary date, but there was no provision for further
renewals.

        4. It was the intention of the parties at the time of the original
Agreement that it continue to renew for consecutive sixty-month periods absent
the occurrence of one of the events specified in Paragraph 2(a) of the
Agreement.

        5. The Bank and the Officer wish to amend the Agreement by deleting the
existing Paragraph 2(a) and substituting in its place a new Paragraph 2(a) which
will provide for continued renewals of the Agreement.

        NOW, THEREFORE, in consideration of the terms and conditions herein
contained and for other good and valuable consideration, the receipt and
sufficiency of which are acknowledged by each party to this Amended Agreement,
the Bank and the Officer agree that Paragraph 2(a) of the Agreement is deleted
and the following Paragraph 2(a) substituted in its place:

           2.   TERMS AND COMPENSATION:

                (a) Term of Agreement. The term of this Agreement shall commence
                on that date upon which the Bank's Board of Directors approves
                the said agreement and shall continue until the first to occur
                of (i) except as otherwise provided in Section 3 hereof, the end
                of the sixtieth consecutive month following the commencement
                date aforesaid, (ii) the Officer's death, or (iii) except as
                provided in Paragraph (d) of this Section 2, the Officer's
                disability. Notwithstanding the foregoing, however, in the event
                the Officer is not informed, in writing, prior to the last day
                of the forty-eighth consecutive month following the Commencement
                date of employment, or any subsequent sixty-month renewal term,
                that this Agreement will not be renewed, this Agreement will
                automatically renew itself for an additional period of sixty
                months from the original anniversary date or, as the case may
                be, any renewal term.

        Except as modified above, the parties ratify and reaffirm the Agreement.

        WITNESS the following signatures and seals as of the day and year first
above written.

                                R E C I T A L S:

        3. The Bank and the Executive wish to further amend the Agreement.

        4. The Bank and the Executive agree that this Second Amendment to
Employment Agreement shall apply to termination for any reason, except where
termination is effective prior to the time "a change in control" (as defined in
Paragraph 3, part (b) of the Employment Agreement) occurs, or prior to the time
the Employer enters into negotiations which result in such change of control, or
where termination is due to or the result of a change in control.

        NOW, THEREFORE, in consideration of the Executive's continued employment
with the Bank and in recognition of the fact that as an employee of the Bank,
the Executive has access to the Bank's customers and to confidential and
valuable business and proprietary information of the Bank, it is further agreed
as follows:

        1.      RETURN OF BANK'S PROPERTY

                When the Executive's employment with the Bank ends, the
Executive agrees to immediately deliver to the Bank all documents, including,
but not limited to, address and telephone records of customers, listings of
customer names and/or account numbers, and any other items or records in the
Executive's possession, or subsequently coming into the Executive's possession
pertaining to the business of the Bank, including without limitation,
confidential and proprietary information which the Executive would not possess
but for his employment relationship with the Bank.

        2.      PROHIBITION OF COMPETITIVE ACTIVITIES

                a. During the Executive's employment with the Bank and for a
period of two (2) years following the Executive's termination, the Executive
agrees that he/she will not, either directly or indirectly, on his/her own
behalf, or on behalf of any other person or entity, or in any capacity call
upon, solicit, divert, take away, or attempt to solicit, divert, or take away
the business or patronage of any client or customer of the Bank.

                b. During the Executive's employment with the Bank and following
termination of employment with the Bank, the Executive will preserve the
confidentiality of, and will not reveal for any reason, or use to the detriment
of the Bank, trade secrets, or other confidential, business, or proprietary
information which the Executive has received in the course of the Executive's
employment with the Bank.

                c. During the period of the Executive's employment and for a
period of two (2) years after employment ends, the Executive agrees that he/she
will not either directly or indirectly, on his/her own behalf or on behalf of
any person or entity, in any capacity, recruit or hire or assist others in
recruiting or hiring any person who is, or was during the period of the
Executive's employment with the Bank, an employee or consultant with the Bank.

        3.      NOTICE OF SUBSEQUENT EMPLOYMENT

                For a period of two (2) years after the Executive's employment
with the Bank ends, the Executive agrees to notify the Bank of the name and
address of the Executive's employer and the Executive hereby authorizes the Bank
to contact any such employer during that period for the limited purpose of
making the employer aware of this Second Amendment to Employment Agreement and
protection against any disclosure of confidential and proprietary information,
or unfair competition.

        4.      REMEDIES

                The Executive acknowledges that if he/she breaches or threatens
to breach this Second Amendment to Employment Agreement, in addition to any and
all other rights and remedies it may have, the Bank shall be entitled to
injunctive relief, both pendente lite and permanent, against the Executive, as
the Executive recognizes that a remedy at law would be inadequate and
insufficient. The Bank shall be entitled to recover from the Executive all costs
and expenses, including but not limited to reasonable attorney's fees and court
costs, incurred by the Bank as a result of or arising out of any breach of
threatened breach under or pursuant to this Second Amendment to Employment
Agreement in addition to such other rights and remedies as the Bank may have
under this Second Amendment to Employment Agreement or any other agreement, at
law or in equity.

                Except as modified by this Second Amendment to Employment
Agreement, the Employment Agreement as previously modified by the Amendment to
Employment Agreement, is ratified and affirmed.

year first above written.

                            secured by a first perfected security interest in

                            At the closing, the Applicable Conversion Price will
                            be equal to the Purchase Price, as hereinafter
                            defined. The Applicable Conversion Price will be
                            subject to future adjustment upon certain dilutive
                            issuances of equity (see "Antidilution Protection"

                                              In addition, the Notes will

                            the closing of a secondary public offering of Common
                            Stock at a public offering price per share (prior to
                            underwriter commissions and expenses) that is not
                            less than three times the Applicable Conversion
                            Price in an offering where the gross proceeds to the
                            Company would be not less than $70,000,000 (a
                            "Qualified Public Offering"); or (ii) the sale of
                            the Company at a minimum price per share in cash or
                            stock, of at least three times the Applicable
                            Conversion Price (a "Qualified Sale"); provided,
                            however, that in the event of a sale of the Company
                            to a privately-held company or to a public company
                            in which disposition of stock would be significantly
                            restricted (by low trading volume or other
                            restrictions), automatic conversion shall occur only
                            in the event of a cash sale. Should either Investor
                            fail to pay an installment of the purchase price
                            under any Note in accordance with the schedule set
                            forth above, the other Investor will have the right
                            but not the obligation to assume the balance of the
                            funding commitment of the defaulting Investor (i.e.,
                            the amount not yet advanced by that Investor to the
                            Company under its Note, either prior to or after the
                            Closing), and in the absence of a cure of such
                            payment default within twenty calendar days of the
                            said due date, the Conversion Amount under the Notes
                            held by such Investor (i.e. the aggregate amount
                            advanced by that Investor under its Note prior to
                            default, both before and after the Closing) shall
                            automatically convert into Common Stock, and the
                            defaulting Investor shall lose all benefits under
                            the Security Agreement, Collateral Assignment
                            Agreement and other related agreements
                            collateralizing the Notes

                                              Antidilution Protection: If the
                            Company at any time issues

                            Common Stock or equity securities convertible or
                            exercisable into Common Stock at a price per share
                            that is less than the Applicable Conversion Price in
                            effect immediately preceding such issuance, the
                            Applicable Conversion Price will be immediately
                            reduced to that price per share at which such
                            securities were issued. The Applicable Conversion
                            Price shall be similarly reduced for successive
                            issuances of equity securities at prices per share
                            that are less than the Applicable Conversion Price
                            in effect immediately preceding such issuances.
                            Notwithstanding the foregoing, no adjustment shall
