pay Executive a base salary (the "Base Salary") at an annual rate of $125,000.

Chief Executive Officer and its Board of Directors based upon the Executive's
performance during the prior year.

to the Executive in quarterly installments, as soon as administratively feasible
after the end of each of the Company's fiscal quarters, in an amount equal to
one-quarter of the incentive compensation that Executive would earn if

to Executive's performance in the most-recently completed fiscal quarter.

Company's Chief Executive Officer. Executive will be paid a pro rata portion of
her salary for each week of accrued and unused paid time off, in accordance

general application in effect at the time of the termination of her employment.

to those that the Company from time to time extends to its senior executive
staff.

          Section 5. Termination. The Company may, at its election and upon
written notice to the Executive, terminate the Executive's employment for any
reason or no reason, with or without cause. Where this Agreement or plan
provides for payment other than by cash lump sum, the Company may, in its sole
discretion, choose to make payment in whole or in part by cash lump sum,
including converting any benefits due to be provided over a period of time into
a cash lump sum equal to the present value, computed at the short-term
applicable federal rate under (S) 1274 of the Internal Revenue Code, of the cost
of the cost of providing such benefit(s) to the Executive over a period of time.

               5.1 Change in Control. For purposes of this Agreement, "Change of

<PAGE>

          (a)  a merger, acquisition, consolidation or other transaction
               involving the Company after which the individuals who constituted
               members of the Board of Directors of the Company or Avatech
               twelve (12) months before the consummation of such transaction do
               not constitute a majority of the Board of Directors or other
               similar governing body of the most senior resulting business
               entity after such transaction;

               Avatech, the Company, or any subsidiaries of either, or more than
               50% of the stock or other equity interests in Avatech, the
               Company, or any subsidiaries of either, to one or more
               organizations or entities not more than 50% owned by the Avatech,
               the Company, or any subsidiaries of either after the consummation

               Board of the Company or Avatech cease for any reason to
               constitute at least a majority thereof unless the election of
               each new director was approved by a vote of at least two-thirds
               of the directors then still in office who were directors at the
               beginning of the twenty-four-month period.

Notwithstanding the foregoing, a Change Of Control will in no event be deemed to
have occurred if the Company is placed in receivership or files for protection
under title 11 of the United States Code, and Executive will not receive any
severance pay under Section 5 of this Employment Agreement if any local, state,
or federal regulator assumes control of the Company.

               5.2 Without a Change in Control (including Nonextension). Except
as provided in Section 5.3, the Company may elect not to extend the Term as
provided in Section 2 or may elect, at any time, to terminate Executive's
employment under this Agreement upon written notice of such termination to
Executive for any reason or no reason, with or without cause. The Executive may
terminate her employment at any time and for any reason upon thirty (30) days'
written notice to the Company.

                    5.2.1 If the Executive's employment terminates under this
Section 5.2, then the Company will pay Executive her Base Salary through the
effective date of termination and any other compensation and benefits that may
be accrued, due, or provided to the Executive upon termination of employment

applicable employee benefit plans of the Company.

benefits to her surviving spouse or other successor in interest in accordance
with the terms of the Company's benefit plans and programs then in effect.

               5.3 Change in Control. If the Executive's employment is
terminated during the term this Agreement and within twelve (12) months before
or twelve (12) months following a Change of Control, the Company will pay
Executive through six (6) months after the effective date of such termination.
Such severance pay will be at a rate equal to Executive's Base Salary in effect
on the effective date of termination and will be paid in accordance with the
Company's general payroll practices.

               5.4 Release. As a condition to receiving payment of amounts
payable under this Section 5, Executive will execute a release of all claims
against the Company in form reasonably satisfactory to the Company.

confidential information relating to the business of Avatech, the Company, its
subsidiaries and affiliates, including but not limited to business plans, sales
and marketing plans, financial information, acquisition prospects, and
"customer" and "supplier" lists (as such terms may relate to the business or the
systems and other trade secrets or know-how of Avatech, the Company, its
subsidiaries and affiliates) as they may exist from time to time (collectively,
"Confidential Information"), which are valuable, special, and unique assets of
the Company's business, access to or knowledge of which is essential to the
performance of Executive's duties hereunder. Accordingly, Executive will not
disclose at any time (during her employment under this Agreement or thereafter)
any such Confidential Information other than in connection with and reasonably
required for the performance of her duties under this Agreement, unless required
to do so pursuant to law, subpoena, court order, or other legal process. These
restrictions will not apply to, and Confidential Information will not be deemed
to include, information that is then in the public domain (other than as a
result of action by the Executive).

               6.2 Competitive Activity. Due to the unique position of Executive
in her role of Senior Vice President of the Company, Executive agrees that if
she voluntarily resigns from her employment, Executive will not, for a period of
six (6) months after the effective date of her termination of employment,
without prior written consent of the Company:

                    6.2.1 Directly or indirectly, knowingly engage or be
interested in (as owner, partner, shareholder, employee, director, officer,
agent, consultant or otherwise), with or without compensation, any business
entity or operation that engages in the business of selling computer-aided
design software or providing professional, consulting, technical or training
services related to computer-aided design software within fifty (50) miles of

place of business, except that Executive may own up to a five percent (5%)
interest in the publicly-traded securities of a publicly traded corporation;

                    6.2.2 Employ or retain or participate in or arrange the
employment or retention of any person who was employed or retained by the
Company, any successor to the Company's business, or any of their affiliates or
subsidiaries during the period of Executive's employment; or

                    6.2.3 Directly or indirectly solicit any customers or
clients of the Company, its affiliates, or subsidiaries.

               6.3 Remedy for Breach and Modification. Executive acknowledges
that the provisions of this Section 6 are reasonable and necessary for the
protection of the Company and that the Company will be irrevocably damaged if
these provisions are not specifically enforced. Accordingly, Executive agrees
that, in addition to any other relief or remedies available to the Company,
including reasonable attorneys' fees and costs, the Company is entitled to seek
and obtain an appropriate injunction or other equitable remedy for the purposes
of restraining the Executive from any actual or threatened breach of or
otherwise enforcing these provisions and no bond or security will be required in
connection with such equitable remedy. If any provision of this Section 6 is
deemed invalid or unenforceable in any jurisdiction, such provision will be
deemed modified and limited in such jurisdiction to the extent necessary to make
it valid and enforceable in such jurisdiction.

          Section 7. Arbitration of Certain Disputes. Any dispute or controversy
arising under or in connection with this Agreement, other than with respect to
an alleged breach of any of any of the provisions of Section 6, shall be
resolved by binding arbitration held in Baltimore, Maryland. before a single
arbitrator. Such arbitration will be conducted in accordance with the Commercial
Arbitration Rules of the American Arbitration Association then in effect and
otherwise in accordance with principles that would be applied by a court of law
or equity. Judgment on any award may be entered and enforced in any court having
jurisdiction.

          Section 8. Miscellaneous.

               8.1 Certain Permitted Changes in Executive's Position. Anything
in this Agreement to the contrary notwithstanding, in the event of a merger,
consolidation, reorganization, sale of substantially all of the Company's
assets, or similar transaction (a "Transaction") (whether or not such
Transaction constitutes a Change of Control as defined in Section 5.1) a change
only in Executive's title (but not a material reduction in the actual scope of
Executive's responsibilities, authority, or duties) does not constitute a
failure by the Company to perform any term or provision of this Agreement. In
the event of such a change in the Executive's title, any reference, whether
express or implied, in this Agreement to Executive's title will be deemed to
refer to Executive's title as so changed.

               8.2 Entire Agreement; Amendment. This Agreement supersedes all
prior agreements between the parties with respect to its subject matter, is
intended as a complete and exclusive statement of the terms of the agreement
between the parties with respect thereto, and may be amended only by a writing
signed by both parties hereto.

               8.3 Nonwaiver. The failure of either party to insist upon strict
adherence to any term of this Agreement on any occasion will not operate as a
waiver or deprive that party of the right thereafter to insist upon strict
adherence to that term or any other term of this Agreement. Any waiver must be
in a writing signed by the party to be charged therewith.

               8.4 Assignment. This Agreement will inure to the benefit of and
be binding upon the parties hereto and their respective heirs, representatives,
successors and assigns. This Agreement may not be assigned by either party
without the consent of the other, except that the Company may assign all of its
rights and delegate performance of all of its obligations hereunder in
connection with a Transaction.

               8.5 Counterparts. This Agreement may be executed in two or more
counterparts, each of which will be an original, but all of which together will
constitute the same instrument.

               8.6 Headings. The headings in this Agreement are for convenience
of reference only and should not be given any effect in the interpretation of
this Agreement.

               8.7 Governing Law. This Agreement is governed by the laws of the
State of Maryland, without regard to any provision that would result in the
application of the laws of any other state or jurisdiction.

               8.8 Severability. The invalidity or unenforceability of any
provision of this Agreement will not affect the validity or enforceability of
any other provision of this Agreement.

               8.9 Company Policies, Plans and Programs. Whenever any rights
under this Agreement depend on the terms of a policy, plan, or program
established or maintained by the Company, any determination of these rights will
be made on the basis of the policy, plan, or program in effect at the time as of
which such determination is made. No reference in this Agreement to any policy,
plan, or program established or maintained by the Company precludes the Company
from prospectively or retroactively changing or amending or terminating that
