         NOW, THEREFORE, in consideration of the mutual covenants herein
contained, and for other good and valuable consideration, the receipt of which
is acknowledged by both parties hereto, the Company and Executive agree as
follows:

         1. EMPLOYMENT. The Company will employ Executive and Executive will
serve the Company as the Company's Chairman and CEO, all upon the terms and
conditions provided herein. Absent consent of Executive, Executive's primary
place of employment shall be within 50 (fifty) miles of 18881 Von Karman,

Agreement, while binding upon the parties hereto, shall become effective only
upon the Closing, as such term is defined in the Merger Agreement, such date

of his duties, Executive shall not be required to travel greater than 50
driving miles from his place of employment more than 25 days within the Term
as defined below.

         3. TERM. The term of Executive's employment hereunder shall be for the
period beginning on the Closing, and ending 90 days after the Closing (the
"Term"). Notwithstanding the scheduled termination date, this Agreement is
subject to earlier termination as set forth in Section 8 hereof.

         4. COMMITMENT OF EXECUTIVE. During the Term, Executive shall be
employed by the Company on a full-time basis, and shall not perform work for
compensation (except for reimbursement of reasonable expenses approved by the
Company) within the industries in which CORE, any of CORE's subsidiaries, or
FBIC are active for any person or entity other than the Company without first
obtaining the prior written consent of the Supervisor.

         5. COMPENSATION.

                  (a) SALARY. During the Term of this Agreement, the Company
agrees to compensate Executive at the rate of not less than Two Hundred Eighty
Thousand Eight Hundred Dollars ($280,800) per annum (a "Base Salary").

                  (b) PAYROLL POLICIES. Executive's compensation shall be paid
in installments pursuant to the Company's personnel policies, as they may be
amended from time to time, less any applicable federal, state or local payroll
tax deductions incident on Executive, as well as any voluntary deductions

                  (c) BONUSES. Executive shall be eligible to receive a bonus at

view of a reasonable person knowledgeable of the situation, (i) Executive made a
reasonable effort to accomplish the goals for the Term established for him by
the Supervisor, (ii) those goals were reasonable given Executive's
responsibilities and resources, and (iii) those goals were in fact met. Though
not the exclusive means of reaching this conclusion, the mutual agreement of the
Supervisor and Executive to end Executive's employment prior to the scheduled
end of the Term (that is, "Termination without Cause" rather than "Termination
for Cause" in the context of this Agreement) will be taken to represent
satisfaction in full of these criteria, and result in payment of the full amount
indicated above.

         6. ETHICAL CONDUCT. Executive agrees to adhere to all recognized
professional ethics and customs, and to avoid all actions or conduct that
injures, directly or indirectly, the professional standing and reputation of the
Company, any of the Company's Affiliates as hereinafter defined, or their
employees. Executive represents and warrants he is free to enter into this
Agreement and that there are no employment contracts, restrictive covenants or
other obligations preventing full performance of his duties hereunder.

                           (i)      willful breach or habitual neglect of the
                                    duties Executive is required to perform
                                    hereunder which are not cured by Executive
                                    within 30 days of written notice from the
                                    Company of such breach or neglect;
                           (ii)     any illegal act by Executive injurious to
                                    the business or reputation of the Company or
                                    any of its Affiliates;
                           (iii)    Executive's engagement in gross misconduct
                                    injurious to the business or reputation of
                                    the Company or any of its Affiliates;
                           (iv)     Executive's conviction of any crime which
                                    constitutes a felony in the jurisdiction
                                    committed (whether or not involving the
                                    Company or any of its Affiliates); or
                           (v)      a material breach by Executive of any
                                    material provision of this Agreement, which
                                    breach is not cured by Executive within
                                    thirty (30) days of written notice from the
                                    Company of such breach.

         If the Company desires to terminate Executive's employment hereunder
for Cause, the Company shall give Executive written notice of the termination
date, which may be immediate, and shall specify in said notice the termination
provision of the Agreement and the factual basis upon which the termination
action is based.

         (b) DISABILITY. Executive's employment hereunder may also be terminated
at the election of the Company in the event that Executive is disabled from
performing his duties hereunder for a period of at least one hundred eighty
(180) continuous days (or such longer period as may be required to satisfy the
qualifying period for benefits under the long-term disability policy sponsored
by the Company and then in effect) during the Term. In the event Executive's
employment is terminated by the Company because of such a disability of
Executive, the Company shall give Executive notice of a termination date, which
shall not be less than thirty (30) days subsequent to the date of the notice,
and Executive's employment hereunder shall terminate on the termination date as
so established by the Company.

         (c) DEATH. Executive's employment hereunder shall terminate
automatically upon the death of Executive.

         (d) EFFECT OF TERMINATION FOR CAUSE, DISABILITY OR DEATH. If
Executive's employment terminates pursuant to Section 8(a), 8(b), or 8(c), the
Company shall pay Executive his Base Salary, accrued but unpaid holiday pay, and
accrued and unused vacation time through the date of termination of Executive's
employment at the rate or

Executive under this Agreement, except for benefits expressly provided in
Section 8(d) and for continuation of benefits required of the Company by
applicable law.

         (e) TERMINATION WITHOUT CAUSE; SEVERANCE. At the scheduled end of the
Agreement Term, or at such earlier date with the agreement of Executive, CORE

employment hereunder shall terminate and Executive shall be entitled to the
following payments or benefits:

                  (i)      all amounts accrued and unpaid to Executive through
                           the termination date, including any Base Salary,
                           accrued but unpaid holiday pay, and accrued but
                           unused vacation time;
                  (ii)     Base Salary for the period from the termination date

                           from the date of termination, in the case of health
                           care coverage, and eighteen (18) months from the
                           scheduled end of the Term, in the case of Base Salary
                           (provided such payments of Base Salary shall be
                           reduced to reflect any salary, consulting fees or
                           other compensation received by Executive for services
                           rendered after one (1) year from the scheduled end of
                           the Term, and further provided, Executive shall
                           timely report to the Company any such compensation).
                           To the extent that such health care coverage cannot
                           by its terms be continued, Base Salary during the
                           severance period with respect to such coverage shall
                           be increased on a grossed-up basis (for the effects
                           of federal and applicable state and local income
                           taxes) to compensate Executive for the actual premium

                           comparable coverage through non-group insurance, if
                           less. Payments under this Section 8(e) shall be made

                           and shall be subject to applicable tax deductions and

                           which Fortis has contracted with Right & Associates
                           (or the lesser of the cost of such package to Fortis
                           or the actual cost to Executive in the event that
                           Executive wishes to select a different outplacement
                           firm) for a period of up to eighteen (18) months
                           following the scheduled end date of the Term, but
                           ending prior to that time if Executive obtains a
                           comparable position, commences a new business, or no

                           forwarding capability), continuation of Executive's
                           cell phone contract and on-line service provider, and
                           retention of current personal computer until the end
                           of the outplacement services according to the terms

                           communications related to the business of the Company

         9. COVENANT NOT TO COMPETE; NON-SOLICITATION; CONFIDENTIAL INFORMATION.

         (a) In consideration of and as an inducement to the Company to enter
into this Agreement, Executive shall not, for a period commencing on the
Effective Date of this Agreement and ending on the later of (i) one (1) year

consultant, independent contractor, officer, director, sole proprietor or
employee of any firm, company, corporation or entity (other than the Company and
its Affiliates) which is engaged within the geographical area of the United
States in competition with the businesses of CORE or any of its Affiliates.
However, in the event that Executive is serving in such fashion, but for a unit
or division of such firm, company, corporation or entity which is not engaged
within the geographical area of the United States in competition with the
business of the Company or any of its Affiliates, then such service shall not
violate this Agreement.

         (b) Executive agrees that for a period commencing on the Effective Date
of this Agreement and ending on the Covenant End Date:

                  (i)      Executive will not directly or indirectly solicit,
                           hire or attempt to hire for any purpose whatsoever
                           (whether as an employee, consultant, advisor,
                           independent contractor or otherwise) any employee or
                           consultant of the Company or any of its Affiliates or
                           any person who was an employee or consultant of any
                           such corporation or corporations (and will use best
                           efforts to prevent any subsequent employer of
                           Executive or related entity or person from taking any
                           such actions);
                  (ii)     Executive will not induce or attempt to induce any
                           customer, client, supplier, licensee or other
                           business relation of the Company or any of its
                           Affiliates to cease doing business with the Company
                           or any of its Affiliates or in any way interfere with
                           the relationship or potential relationship between
                           any such customer, client, supplier, licensee or
                           business relation, and the Company or any of its
                           Affiliates; and
                  (iii)    Executive shall not solicit or attempt to solicit, or
                           accept business from, any entity which at any time
                           during the twelve month period prior to the date of
                           termination of Executive's employment with the
                           Company, was a client or customer of the Company or
                           any of its Affiliates for the purpose of doing
                           business with such client or customer in matters that
                           compete with the business of the Company or any of
                           its Affiliates. For the purpose of this covenant, the
                           clients and customers of the Company or any of its
                           Affiliates shall include those entities with which
                           the Company or any of its Affiliates had held
                           discussions or negotiations concerning services of
                           the Company or any of its Affiliates.

         (c) PUBLICLY-HELD STOCK. Nothing herein contained shall prevent
Executive from holding or making an investment in:

                  (i)      securities listed on a national securities exchange
                           or sold in the over-the-counter market, provided that
                           such investments do not exceed in the aggregate five
                           percent (5%) of the issued and outstanding capital
                           stock of a corporation which is a competitor of the
                           Company or any of its Affiliates within the meaning
                           of this Section; or
                  (ii)     interests in a mutual fund or other pooled investment
                           vehicle in which Executive has less than a five
                           percent (5%) interest.

         (d) CONFIDENTIAL INFORMATION. Executive has previously executed and
delivered to CORE the Company's standard non-disclosure agreement with respect
to confidential information. Executive hereby re-affirms all his obligations
pursuant to the Company's standard non-disclosure agreement in the form attached
hereto as EXHIBIT A, which is hereby made a part of this Agreement.

         (e) INJUNCTIVE RELIEF. Without intending to limit the remedies
available to the Company or any of its Affiliates, Executive acknowledges that a
breach of any of the covenants contained in this Agreement could result in
material irreparable injury to the Company or any of its Affiliates for which
there might be no adequate remedy at law, and that, in the event of such a
breach or threat thereof, the Company or any of its Affiliates shall be entitled
to obtain a temporary restraining order and/or a preliminary and permanent
injunction restraining Executive from engaging in any activities prohibited by
this Agreement or such other equitable relief as may be required to enforce
specifically any of the covenants of this Agreement.

         (f) REASONABLENESS OF RESTRICTIONS. The parties are of the view that
the restrictions placed on Executive herein, in the light of all the
circumstances are reasonable as to scope, period of time and geographical area.
Nevertheless, it is the intent of the parties that this Agreement be enforceable
and restrict Executive's activities only to the extent permitted by law.
Accordingly, in the event that any provisions in this Agreement shall be
determined by arbitrators or by any court of competent jurisdiction to be
unenforceable by reason of its extending for too great a period of time over too
large a geographic area or range of activities, it shall be interpreted to
extend only over the maximum period of time, geographic area or range of
activities as to which it may be enforceable.

         (g) DEFINITION OF "AFFILIATE." For the purposes of this Agreement,
"Affiliate" with respect to CORE shall mean FBIC and the direct and indirect
subsidiaries of CORE itself.
