Termination for Death or Disability. In the case of a termination of Executive's
employment hereunder by mutual agreement, for Death or Disability in accordance
with Section 1.5.2 above, or Executive's Voluntary termination of employment
hereunder in accordance with Section 1.5.3 above, or a termination of

above, (a) Executive shall not be entitled to receive payment of, and Company
shall have no obligation to pay, any severance or similar compensation
attributable to such termination, other than Base Salary earned but unpaid,

(b) Company's obligations under this Agreement shall immediately cease.

                  1.6.2  Termination Without Cause by Company or For Good Reason
by Executive. Subject to the provisions set forth in this Agreement, in the case
of a termination of Executive's employment hereunder Without Cause in accordance
with Section 1.5.5 or for Good Reason by Executive in accordance with Section

should Company fail to do so in breach of this Agreement, and Company shall
continue to pay Executive's Base Salary for either (a) in the case of where the
effective date of the Termination occurs during the Initial Term or (b) in the
case where the effective date of the Termination occurs during a Renewal Term,
then for a period of one-hundred eighty (180) days following the such date
(hereinafter the "Severance Payments"), payable in installments in accordance
with Company's normal payroll practices and subject to the tax withholding
specified in Section 1.4.1 above. If Executive elects to continue health
coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985
("COBRA"), BV shall cause Company to pay and Company will pay Executive's COBRA
premiums in an amount sufficient to maintain the level of health benefits in
effect on Executive's last day of employment (hereinafter "Benefit
Continuation"), until the earlier of (i) the end of the COBRA coverage period,
(ii) the termination of any period in which Executive receives the Severance
Payments under this Section, or (iii) the date Executive receives comparable
benefits from any other source, whichever occurs first. Nothing contained herein
shall interfere with Executive's right to continue his continuation coverage
under COBRA.

                  1.6.3  Severance Conditioned on Release of Claims. BV and
Company's obligation to provide Executive with the Severance Payment and Benefit

                                        5

Continuation set forth in Section 1.6.2 is contingent upon Executive's execution
of a release of claims reasonably satisfactory to and in favor of Company.

                  1.6.4  Offset Against Severance. During any period in which
Executive is receiving Severance Payments from Company (the "Severance Period"),
such Severance Payments to be provided to Executive shall be reduced on a
dollar-for-dollar basis by any wages or other compensation actually received by
Executive during the Severance Period, regardless of whether such wages or
compensation are from employment, consulting, or other gainful activities.
Executive promises and agrees to promptly advise Company of the amount and
source of any wages or other compensation received by him, from any source,
during the Severance Period and use reasonable efforts to secure substitute
employment or other source of income consistent with Executive's position and
experience.

                  1.6.5  WARN Act Offset. In the event that Executive's
termination Without Cause in accordance with Section 1.5.5 above is covered by
the Worker Adjustment Retraining Notification Act ("WARN") at the time of
Executive's termination, or is deemed to be covered by WARN retrospectively
within 90 days after Executive's termination, the amount of any Severance
Payment or Benefit Continuation Executive is entitled to receive pursuant to
Section 1.6.2 shall be reduced by an amount equal to any payments Company is
required to provide Executive under WARN or by the amount of pay Executive
receives during any portion of WARN's 60-day notice period where Executive does
not perform any work for Company.

      2.    REPRESENTATIONS AND WARRANTIES BY EXECUTIVE

Executive represents and warrants to BV and Company that (a) this Agreement is
valid and binding upon and enforceable against him in accordance with its terms,
(b) Executive is not bound by or subject to any contractual or other obligation
that would be violated by his execution or performance of this Agreement,
including, but not limited to, any non-competition agreement presently in

Agreement or the business reputation of Company. Executive has not entered into,
and agrees that he will not enter into, any agreement either written or oral in
conflict herewith.

            3.12  GOVERNING LAW AND JURY TRIAL. THIS AGREEMENT SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF SOUTH CAROLINA
APPLICABLE TO CONTRACTS EXECUTED AND PERFORMED IN SUCH STATE WITHOUT GIVING
EFFECT TO CONFLICTS OF LAWS PRINCIPLES. BECAUSE DISPUTES ARISING IN CONNECTION
WITH COMMERCIAL MATTERS, INCLUDING EMPLOYMENT AGREEMENTS, ARE MOST QUICKLY AND
ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH
APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE
PARTIES DESIRE THAT THEIR DISPUTES (IF ANY) BE RESOLVED BY A JUDGE APPLYING SUCH
APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF
THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE,
WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN THE PARTIES ARISING OUT
OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH THIS EMPLOYMENT AGREEMENT OR MATTERS RELATED
HERETO.

            3.13  JURISDICTION. The parties hereby consent to the personal
jurisdiction and venue of any court physically located within the County of
Richland, South Carolina in connection with any legal or equitable action
between the parties arising out of or in connection with this Agreement.

            3.14  COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by facsimile, each of which will be deemed an original, but all
of which together will constitute one and the same instrument.

            3.15  OPPORTUNITY TO OBTAIN COUNSEL. In connection with the
preparation of this Agreement, Executive acknowledges and agrees that: (a) this
Agreement was prepared by legal counsel to Company (the "Law Firm") solely on
behalf of Company and not on behalf of Executive; (b) Executive has been advised
that his interests may be opposed to the interests of Company and, accordingly,
the Law Firm's representation of Company in the preparation of this Agreement
may not be in the best interests of Executive; and (c) Executive has been
advised to retain separate legal counsel. Executive warrants and agrees that he
has had a reasonable opportunity to obtain independent legal counsel with regard
to the terms and conditions of this Agreement, and has read and fully
understands the terms and conditions of this Agreement. If Executive elects not
to consult with any such counsel, he has done so freely and of his own volition.
By signing this Agreement, Executive is affirming that he has freely and of
Executive's own volition acknowledged and agreed to all terms and conditions
contained in this Agreement.

            3.16  CONSTRUCTION AND INTERPRETATION. Should any provision of this
Agreement require judicial interpretation, the parties hereto agree that the
court interpreting or construing the same shall not apply a presumption that the
terms hereof shall be more strictly construed against one party by reason of the
rule of construction that a document is to be more strictly construed against
the party that itself, or through its agent, prepared the same, and it is

                                        9

expressly agreed and acknowledged that Company, BV and Executive and each of his
and its representatives, legal and otherwise, have participated in the
preparation hereof.

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed on the date first set forth above.

      WHEREAS, BV, Company and Executive entered into that certain Employment
Agreement, dated January 25, 2006 (the "Employment Agreement"), which provides
for the employment of Executive by Company as Director, Operations of BV; and

      WHEREAS, the parties desire to amend the Employment Agreement as provided
herein.

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties agree as follows:

      1.    Section 1.42 Incentive Bonus. Section 1.42 of the Employment
Agreement shall be deleted in its entirety, with no further force and effect
hereafter, and replaced with the following:

            "Section 1.42 Performance Based Cash Bonus. In addition to any other
      compensation paid to Executive under this Agreement, Executive's right to
      receive and BV's obligation to pay an incentive bonus shall be subject to
      Executive's satisfaction of performance criteria as determined by BV's
      Board of Directors in its sole and absolute discretion."

      2.    Each of the parties to this Amendment acknowledge and agree that,
except as modified hereby, all of the terms and provisions of the Employment
Agreement shall remain in full force and effect.

      3.    This Amendment is the sole agreement between the parties as to the
amendment and modification of the Employment Agreement as described herein.

      4.    This Amendment may be executed in any number of counterparts, each
of which shall be deemed to be an original as against any party whose signature
appears thereon, and all of which shall together constitute one and the same
instrument. Invalidation of any one or more of the provisions of this Amendment
shall in no way affect any of the other provisions of this Amendment, which
shall remain in full force and effect.

      5.    This Amendment shall be binding upon and shall inure to the benefit
of the parties hereto and their respective heirs, executors, successors,
personal representatives and assigns.

      6.    This Amendment shall be governed by and construed in accordance with
the laws of the State of South Carolina.

      IN WITNESS WHEREOF, the parties have executed this Amendment as of the
date first above written.
