                                    RECITALS

         A. Pursuant to an Agreement and Plan of Merger (the "Merger
Agreement"), Cortez Acquisition Corporation, a North Carolina corporation (the
"Merger Subsidiary") has been merged into Employer, and Employer has become a
wholly owned subsidiary of Cortez.

         C. Cortez has required that Employee enter into this Agreement with
respect to the services she will provide to Employer after the merger.

contained herein, and other good and valuable consideration, the parties agree
as follows:

         Section 1. Term. The employment created by this Agreement shall be for
a three (3) year term beginning on the effective date of the Merger Agreement
and ending December 31, 2003 (the "Term"), and automatically renewable at the
option of Employee for an additional two (2) year period, subject, however, to
earlier termination as provided herein.

         Section 2. Duties. Employee is initially engaged to act in the capacity
of Director of Development, subject to change as appropriate to the needs of the

and at that time Employer shall determine whether Employee's salary should be
increased.

available for Employer's employees generally.

         Section 7. Expenses. Employer shall reimburse Employee for business
expenses directly and reasonably incurred in the performance of his duties
provided that Employee complies with Employer's policies concerning
reimbursement for such expenses.

         Section 8. Termination. This Agreement shall terminate prior to the
expiration of its Term upon the occurrence of any one of the following events:

                  (a) Disability. In the event that (i) Employee is totally and
permanently disabled as determined in accordance with the Employer's long-term
disability plan, if any, as in effect at such time, or (ii) if no such plan is
in effect, Employee is unable to perform his duties and responsibilities
hereunder by reason of illness, injury or incapacity for ninety (90) consecutive
days, this Agreement may be terminated by Employer, and Employer shall have no
further liability or obligation to Employee for compensation hereunder;
provided, however, that Employee shall continue to be compensated as provided in
Section 3 of this Agreement during such 90-day period and until termination
under this section, and provided further, that Employee will be entitled to
receive the payments prescribed under any disability benefits plan in which
Employee was participating.

                  (b) Death. In the event that Employee dies during the Term,
Employer shall pay to his executors, legal representatives or administrators an
amount equal to the remaining installment of Employee's compensation set forth
in Section 3 hereof for the month in which Employee dies, and thereafter
Employer shall have no further liability or obligation hereunder to Employee's
executors, legal representatives, administrators, heirs or assigns or any other
person claiming under or through Employee; provided, however, that Employee's
heirs, legal representatives or administrators will be entitled to receive the
payments prescribed under any death or disability benefits plan in which
Employee was participating.

                  (c) Cause. Nothing in this Agreement shall be construed to
prevent Employee's termination by Employer at any time for "cause". For purposes
of this Agreement, "cause" shall mean (i) the failure of Employee to perform or
observe (other than by reason of illness, injury or incapacity) any of the
material terms or provisions of this Agreement, (ii) dishonesty or misconduct


                                      E-26

on the part of Employee that is or is reasonably likely to be materially
damaging or materially detrimental to the business of Employer, (iii) conviction
of a felony, (iv) failure to comply with the reasonable directions of the Board
of Directors or officers of the Employer in a way that is materially damaging or
materially detrimental to the business of Employer, or (v) failure to perform
his material duties under this Agreement due to abuse of alcohol or drugs. Prior
to terminating this Agreement on account of Employee's failure to perform or
observe any of the material terms and conditions of this Agreement (as described
in clauses (i), (iv) or (v) of the preceding sentence), Employer shall give
Employee thirty (30) days' written notice and an opportunity to cure such
failure to the satisfaction of Employer. Upon termination for cause, Employer
shall pay to Employee all sums due Employee through the date of such
termination. Following such termination, Employer shall have no further duty or
obligation to Employee; provided, however, that Employee shall continue to be
bound by Section 9.

         Section 9. Confidential Information. Employee may gain access to or
knowledge of information about Employer that is not generally known or available
to the public ("Confidential Information"). Such information may include trade
secrets, research, development, client information, marketing plans, contractual
arrangements, personnel records, finances, and clients lists. Employee will not
disclose any Confidential Information during or after the term of this Agreement
to any person, firm, corporation, association or other entity for any reason or
purpose whatsoever or use such information except as directed or authorized by
Employer. All Confidential Information remains the property of Employer and no
license or other rights to Confidential Information is granted hereby. On demand
of Employer, at any time, Employee shall immediately deliver all printed or
written Confidential Information to Employer. Confidential Information includes
any such information of Employer prior to the merger of Merger Sub into
Employer.

         The following information shall not be deemed part of the Confidential
Information: (1) that was in the public domain at the time of disclosure by
Employer to the Employee; or (2) that entered the public domain through no fault
of Employee subsequent to the time of disclosure by the Employer to Employee; or
(3) that was in the Employee's possession free of any obligation of confidence
at the time of disclosure by the Employer; or (4) that was rightfully
communicated by a third party to Employee free of any obligation of confidence
subsequent to the time of disclosure by the Employer to Employee; or (5) that is
deemed not confidential by the Board of Directors of Employer or is not
confidential under any confidentiality policies adopted by the Board of
Directors of Employer.

         Section 10. Ownership of Confidential Information and Work Product.
Except as limited by this Section, Employee agrees that all Confidential
Information and all other work product of any type or nature created by Employee
or resulting from work performed by Employee for the Employer, using the
Employer's facilities, equipment, supplies or other property, during business
hours, or related to the Employer's Business, even if not Confidential
Information (such Confidential Information and work product being defined as
"Work Product"), shall belong to the Employer exclusively and without any
additional compensation to Employee. Employee agrees that any original
copyrightable Work Product shall be considered as "works made for hire," and
that the Employer shall be deemed the author thereof, provided that to the
extent such Work Product is


                                      E-27

<PAGE>



determined not to constitute "works made for hire" as a matter of law, Employee
hereby irrevocably assigns and transfers to the Employer all rights in and to
such Work Product.

         Upon request Employee will execute any instrument required to vest in
the Employer complete title and ownership to all Work Product, and will, at the
request and expense of the Employer, execute any instruments necessary to obtain
legal protection in the United States and foreign countries for all Work Product
and for the purpose of vesting title thereto in the Employer, or its nominee,
all without any additional compensation of any kind to Employee.

force and effect, and in substitution for any such provision held unlawful,
there shall be substituted a provision of similar import reflecting the original
intent of the Parties hereto to the extent permissible under law.
