termination of the Employee's employment hereunder), or if unable to do so, to
pay to the Employee the cost to the Company (on a cost responsibility basis
substantially comparable to that which was in effect immediately prior to such
termination of the Employee's employment hereunder) of, all medical, dental and
other health insurance benefits to be provided to or for the benefit of the
Employee pursuant to Section 5.4 hereof that would have otherwise been provided
to the Employee if the Employee's employment had continued during and through
the Good Reason After Change in Control Severance Period, provided that the
Company's obligation to continue to provide the Employee with such medical,
dental and other health insurance benefits shall be conditioned upon the
Employee continuing to pay to the Company that portion of premiums associated
with such insurance benefits which was the Employee's responsibility immediately
prior to such termination of the Employee's employment hereunder;

All of the monetary amounts, if any, payable by the Company to the Employee
pursuant to this Section 4.3(a) shall be (i) payable based upon the level of
compensation and other monetary amounts in effect immediately prior to the
termination of the Employee's employment hereunder, (ii) payable in accordance
with the applicable terms and conditions of this Agreement as if the Employee
were still employed by the Company (or in a lump sum amount if the Board in its
discretion so chooses at any time), and (iii) subject to any deductions or
offsets described in this Agreement. For purposes of the foregoing, the level of
bonus described in Section 5.3 hereof in effect immediately prior to such
termination of the Employee's employment hereunder shall (A) if such bonus was
based upon a formula which can still be consistently applied during and through
the Death/Disability Severance Period, Good Reason Before Change in Control
Severance Period or Good Reason After Change in Control Severance Period, as the
case may be, the amount determined based upon such formula, or (B) if such bonus
is not based upon a formula which can still be consistently applied during and
through the Death/Disability Severance Period, Good Reason Before Change in
Control Severance Period or Good Reason After Change in Control Severance
Period, as the case may be, the amount of bonus payable to the Employee for the
previous fiscal year of the Company. All of the medical, dental and other health
insurance benefits to be provided by the Company to the Employee pursuant to
this Section 4.3(a) shall be (i) provided based upon the Employee's position,
and such insurance benefits provided to the Employee, immediately prior to the
termination of the Employee's employment hereunder, and (ii) provided in
accordance with the applicable terms and conditions of this Agreement.
Notwithstanding the foregoing, in the event of the termination of the Employee's
employment pursuant to Section 4.1(a) hereof, the Company shall pay or provide,
as the case may be, the compensation and benefits described in Section 4.3(a)
hereof to the Employee's estate and the Employee's dependents, as the case may
be, and in the event of the Employee's subsequent death after any termination of
the Employee's employment hereunder pursuant to Section 4.1(b), (c), (d), (e) or
(f) hereof, the Company shall pay or provide, as the case may be, the
compensation and benefits described in Sections 4.3(a) hereof to the Employee's
estate and the Employee's dependents, as the case may be.

                           (b) Mitigation. The Employee shall not be required to
mitigate the amount of any payment or benefit provided for in this Section 4.3
by seeking other employment or otherwise. Notwithstanding the foregoing, the
amount of any payment or benefit provided for in Section 4.3(a)(ii), (iii) or
(iv) hereof shall be reduced by any compensation earned by or benefit provided
to the Employee as the result of employment by another employer during the
Death/Disability Severance Period, Good Reason Before Change in Control
Severance Period, or Good Reason After Change in Control Severance Period, as
the case may be, provided that with respect to insurance benefits such benefits
must be comparable in scope of coverage and cost responsibility basis for the
Employee in order to qualify for offset. The Employee shall promptly notify the
Company of any such subsequent employment and provide the Company with
information reasonably required to make any such offset. Notwithstanding any
provision of this Agreement to the contrary, any breach or alleged breach by the
Employee of the Employee's obligations under Section 6 hereof after the
termination of the Employee's employment hereunder shall not expressly or
implicitly provide or bestow any right to or on the Company to discontinue or
delay in any way the payment or benefit obligations to the Employee pursuant to
this Agreement, and in any such situation or circumstance, the Company shall
rely exclusively upon the Company's rights to seek legal and equitable remedies
in a court of competent jurisdiction to restrain the Employee's failure or
refusal to perform or comply with the Employee's obligations under Section 6
hereof after the termination of the Employee's employment hereunder.

                  4.4 In addition to the foregoing, in the event of termination
of Employee's employment pursuant to Section 4.1(d) hereof:

                           4.4.1 all rights of Employee pursuant to awards of
options granted by the Company shall be deemed to have fully vested and be fully
exercisable and all rights of Employee pursuant to share grants and option
awards shall be released from all conditions and restrictions imposed upon such
grants and awards, which conditions and restrictions were initially imposed by
the Company, provided that the foregoing shall in no way affect or extinguish
the Note or the Pledge and the Employee's obligations thereunder.

                           4.4.2 the Employee shall be deemed to be credited
with service with the Company for the Good Reason Before Change in Control
Severance Period or Good Reason After Change in Control Severance Period, as the
case may be, for the purposes of the Company's benefit plans; and

                           4.4.3 the Employee shall be deemed to have retired
from the Company and shall be entitled as of the termination date, or at such
later time as he may elect, to commence receiving the total combined qualified
and non-qualified retirement benefit to which he is entitled hereunder, or his
total non-qualified retirement benefit hereunder if under the terms of the
Company's qualified retirement plan for salaried employees, he is not entitled
to a qualified benefit.

                           4.4.4 If any provision of this Section 4.4 cannot, in
whole or in part, be implemented and carried out under the terms of the
applicable compensation, benefit, or other plan or arrangement of the Company
because the Employee has ceased to be an actual employee of the Company, because
the Employee has insufficient or reduced credited service based upon his actual
employment by the Company, because the plan or arrangement has been terminated
or amended after the effective date of this Agreement, or because of any other
reason, the Company itself shall pay or otherwise provide the equivalent of such
rights, benefits and credits for such benefits to Employee, his dependents,
beneficiaries and estate.

         5. COMPENSATION AND BENEFITS. In consideration of Employee's services
and covenants hereunder, Company shall pay to Employee the compensation and
benefits described below (which compensation shall be paid in accordance with
the normal compensation practices of the Company and

                                       9
<PAGE>   10

shall be subject to such deductions and withholdings as are required by law or
reasonable policies of the Company in effect from time to time, except as
otherwise provided in this Section 5):

                  5.1 Signing Bonus. The Company shall pay Employee a cash

                  5.2 Annual Salary. During the Term, the Company shall pay to
Employee a base salary at the initial rate of $240,000 per year in accordance
with the Company's regular payroll policy, or according to such other schedule
as Employee and the Company may agree to. The Board shall be entitled to review
Employee's base salary at any time and from time to time (but not less
frequently than on each anniversary of the Effective Date) and may increase the
rate thereof at any time and from time to time in the Board's sole discretion.
The Board shall not decrease, at any time, the rate of the Employee's base
salary then in effect.

                  5.3 Bonus. During the Term, in addition to the above salary,
the Company shall pay to Employee a cash bonus at the initial rate of
$100,000.00 per fiscal year subject to the performance standards with respect to
the Company included in APPENDIX A attached hereto; provided, however, that
Employee is hereby guaranteed to receive a minimum $100,000 bonus for the
Company's 2000 fiscal year. The Board shall be entitled to review the Employee's
cash bonus at any time and from time to time (but not less frequently than on
each anniversary of the Effective Date) and may increase or decrease (but not
for the Company's 2000 fiscal year) the rate thereof at any time and from time
to time in the Board's sole discretion.

                  5.4 Benefits. During the Term, Employee shall be entitled to
share in any employee benefits generally provided by the Company to its most
highly ranking employees and officers for so long as the Company provides such
benefits and to any other benefits given to Employee in the sole discretion of
the Board.

                  5.5 Discretionary Funds. During the Term, at the Employee's
discretion, the Company shall spend up to $50,000.00 per fiscal year for
purposes of the Employee's choosing; provided, however, that the CEO must give
his prior approval in writing for any such expenditure made to the Employee
himself, any family member of Employee (whether by blood, marriage or adoption
and not more remote than first cousin), or any entity 5% or more of the equity
securities of which are beneficially owned by the Employee and/or any family
member of the Employee, which approval may be withheld at the sole discretion of
the CEO.

                  5.6 Relocation Expenses. The Company shall pay directly to
third parties or reimburse Employee in accordance with the Company's then
current accounts payable process for all reasonable expenses incurred by
Employee in moving to or within thirty (30) miles of Greenville County, South
Carolina in connection with his employment with the Company, provided that
Employee provides the Company with written documentation as required under the
Company's policies and procedures to support payment or reimbursement. Such
expenses shall include travel costs for Employee and his immediate family to
Greenville County, the cost of shipping Employee's personal property to
Greenville County, the cost of storing such property for up to six months from
the Effective Date until Employee has purchased a residence in or near
Greenville County, real estate agent commissions and fees, mortgage application

                                       10
<PAGE>   11

                  5.7 Business Expenses. As a condition of employment, Employee
is required to incur reasonable and necessary expenses for the promotion of the
business of the Company, including without limitation, expenses of
entertainment, travel, telephone costs and similar expenses. Provided that
Employee provides the Company with reasonable written documentation as required
under the Company's policies and procedures to support reimbursement, the
Company shall reimburse Employee for all such expenses reasonably incurred by
Employee in the performance of his duties under this Agreement in accordance
with the Company's then current expense reimbursement process.

                  5.8 Stock Options. On the Effective Date, Employee shall be
granted by the Company, pursuant to the Company's Employee Incentive Plan (a
copy of which has been furnished to the Employee), an option to purchase 750,000
shares of the Common Stock at an exercise price of $3.00 per share, which option
shall vest with respect to 20% of such shares on each of the first five
anniversaries of the Effective Date so long as Employee continues to be employed
by the Company (except as otherwise provided in Section 4.4.1 hereof). Such
option shall be granted pursuant to a grant letter with terms and conditions
typical of those contained in grant letters from the Company to its employees
under the Company's Employee Incentive Plan. The options granted pursuant to
this Section 5.8 shall be options intended to qualify as Incentive Stock Options
under Section 422 of the Code or any successor provision, provided that to the
extent such options do not meet such qualifications, such options shall be
non-qualified stock options.

                  5.9 Liquidity Bonus. If an IPO or a Sale of the Company occurs
while the Employee is still employed by the Company pursuant to the terms of
this Agreement (except as otherwise provided in Section 4(a)(iv)), Employee
shall be entitled to receive, and the Company shall pay to the Employee, a
"Liquidity Bonus" of cash in the amount of (a) $500,000 in the event that either
the Pre-IPO Value of the Company or the value of the Company based upon the
consideration payable in connection with such Sale of the Company, as the case
may be, is at least equal to $500,000,000 but less than $750,000,000, or (b)
$750,000 in the event that either the Pre-IPO Value of the Company or the value
of the Company based upon the consideration payable in connection with such Sale
of the Company, as the case may be, is at least equal to $750,000,000.
Notwithstanding the foregoing, if the Employee receives the Liquidity Bonus as
the result of an IPO, the Employee may elect to receive all or any portion of
the Liquidity Bonus in Common Stock in lieu of cash, in which case, the number
of shares of Common Stock he receives shall equal the dollar value of such
portion of the Liquidity Bonus divided by the average offering price of Common
Stock sold in the IPO. Any Common Stock acquired by Employee as part of the
Liquidity Bonus shall be restricted stock as defined in Rule 144 promulgated
under the Securities Act and the certificates representing such stock shall bear
legends substantially of the form of legend in Section 5.10.4 of this Agreement.
The Company shall pay or otherwise deliver the Liquidity Bonus to the Employee
no later than sixty (60) days after the occurrence of the event giving rise to
the Company's obligation to pay the Liquidity Bonus.

                  5.10 Stock Purchase. On the Effective Date, Employee shall
purchase 81,178 shares of the Common Stock for $4.25 per share and 212,940
shares of the Series C Preferred Stock for $4.25 per share (for a total of
$1,250,001.50) pursuant to the terms of this Subsection 5.10.

                           5.10.1 On the Effective Date, the Company shall issue
in Employee's name a certificate representing 176,470 shares of the Series C
Preferred Stock (the "Credit Shares"), and the Employee shall deliver to the
Company a promissory note in the form of EXHIBIT A attached hereto in an
aggregate principal amount of $749,997.50 (the "Note"). Employee's obligations
under the Note shall be secured by a pledge to the Company of the Credit Shares
as provided in a pledge agreement in the form of EXHIBIT B attached hereto (the
"Pledge").

                           5.10.2 Pursuant to the requirements of South Carolina
law, the Credit Shares shall be held in escrow by the Company. Any cash
distributions in respect of the Credit Shares shall be

                                       11
<PAGE>   12

applied against the principal amount of the Note (and any interest thereon). Any
non-cash distributions or other property received as an addition to, in
substitution of, or in exchange for any of the Credit Shares (whether as a
distribution in connection with any recapitalization, reorganization or
reclassification, a stock dividend or otherwise), shall be escrowed with the
Credit Shares. The Credit Shares and any escrowed non-cash distribution proceeds
or other property shall remain in escrow until the Note is paid in full, except
as otherwise provided in the Pledge.

                           5.10.3 On the Effective Date, the Company shall issue
to Employee a certificate representing 81,178 shares of the Common Stock and a
certificate representing 36,470 shares of the Series C Preferred Stock
(collectively the "Cash Shares"), and the Employee shall pay to the Company
$4.25 per share in cash (for a total of $500,004.00) in consideration for the
Cash Shares.

                           5.10.4 Each certificate evidencing the Common Stock
and the Series C Preferred Stock purchased by Employee pursuant to the terms of
this Subsection 5.10 shall bear a legend in substantially the following form:

         The securities represented by this certificate were issued to an
         affiliate, as defined in Rule 144 promulgated under the Securities Act
         of 1933, as amended (the "Securities Act"), of the issuer without
         registration under the Securities Act or the securities laws of any
         state in a transaction believed to be exempt from such registration.
         The securities represented by this certificate may not be resold unless
         such resale is registered under the Securities Act and applicable state
         securities laws or is exempt from such registration.

                  5.11 Representations and Warranties of Employee. In connection
with the acquisition of Common Stock as contemplated in this Agreement, Employee
hereby makes the representations and warranties to the Company contained in
EXHIBIT C attached hereto.

         6. CONFIDENTIALITY; NON-COMPETITION.

                  6.1 Covenant Term. Employee covenants and agrees that for so
long as he is employed by the Company hereunder and a period of two (2) years
thereafter (provided that if the Employee is eligible to receive compensation
and benefits from the Company upon termination of the Employee's employment
pursuant to Section 4.1(d) hereof, such post-employment period shall be the
shorter in duration of (i) two (2) years after such termination of employment,
and (ii) the Good Reason Before Change in Control Severance Period or Good
Reason After Change in Control Severance Period, as the case may be) (the
"Covenant Term"), he will not, directly or indirectly, engage in any activity
prohibited pursuant to the terms of this Section 6.

                  6.2 Non-Competition. Employee agrees that for the Covenant
Term, he will not, without the prior written consent of the Company, directly or
indirectly, (i) own, manage, operate, control or participate in, or be
associated with as a director, officer, shareholder, partner, joint venturer,
employee, consultant or otherwise, any business providing telecommunications
services including, but not limited to, local exchange or long distance
telecommunications services which competes, directly or indirectly, with the
Company within any metropolitan statistical service area in which the Company
provides such services on the date of termination of Employee's employment (the
"Prohibited Business"); (ii) own any equity security in any person or entity
engaged in any such Prohibited Business, other than as a passive investor
owning, directly or indirectly, not more than 5% of the equity securities of a
public corporation; (iii) solicit or attempt to solicit any employee of the
Company either to work for the Employee personally or on behalf of any other
person or entity whether or not engaged in a Prohibited Business; or (iv)
solicit or attempt to solicit, for the purpose of providing the services
identified in subpart (i) above, any customer of the Company with which the
Employee had material contact during the twelve-month period immediately prior
to the Employee's departure from the Company. Notwithstanding

                                       12
<PAGE>   13

the foregoing, the Company acknowledges and agrees that the Employee currently
holds ownership interests and options in BellSouth Corporation. The Company
acknowledges and agrees that the Employee's current or future ownership
interests in BellSouth Corporation or any successor entity which may otherwise
be prohibited by this Section 6.2, shall be deemed not to constitute a breach of
this Section 6.2 by the Employee.

                  6.3 Non-Disclosure of Confidential Information. As used in
this Agreement, the term "Confidential Information" shall mean any information
which (i) is not generally available to the public or within the Company's field
of industry; and (ii) pertains to or relates in any way to the Company or its
businesses, proprietary techniques, know-how, independent interpretations of
market information, strategic plans and organizational approaches, activities,
products or services including, without limitation, financial information,
analyses, intellectual property rights, employee compensation information,
reports, pricing methods or other trade secrets. Employee acknowledges that he
may come into possession of certain Confidential Information of the Company or
its affiliates, and agrees that all such Confidential Information is the sole
and exclusive property of the Company. Other than in connection with Employee's
employment with the Company, during the Covenant Term, Employee shall not
disclose any such Confidential Information, directly or indirectly, nor use it
in any way, either during the Covenant Term or at any time thereafter, except as
required by law or by any court or governmental agency or body. All files,
records, documents, pricing and other information, data and similar items in any
medium whatsoever relating to the business, assets or prospects of the Company
or its affiliates, whether prepared by Employee or otherwise coming into his
possession, shall remain the exclusive property of the Company and, other than
in connection with Employee's employment with the Company, shall not be copied
or removed from the premises of the Company without the Company's prior written
consent. The terms of this Section 6.3 are not intended to limit any
definitions, protections or remedies available to the Company under any local,
state or federal law applicable to trade secrets or confidential information.

                  6.4 Remedies. Employee acknowledges that any violation of this
Section 6 will cause irreparable harm to the Company and that damages are not an
adequate remedy. Employee therefore agrees that the Company shall be entitled to
injunctive relief enjoining, prohibiting and restraining Employee from the
continuance of any such violation, in addition to any monetary damages which
might occur by reason of a violation of this Section 6 or any other remedies at
law or in equity, including, without limitation, specific performance.

                  6.5 Independent Covenants. The covenants set forth in this
Section 6 are and shall be deemed and construed as separate and independent
covenants. Should any part or provision of such covenants be held invalid, void
or unenforceable by any court of competent jurisdiction, such invalidity or
unenforceability shall not render invalid, void or unenforceable any other part
or provision thereof. Specifically, and without limiting the generality of the
foregoing, if any portion of this Section 6 is found to be invalid by a court of
competent jurisdiction because its duration, the territory and/or the restricted
activities are invalid or unreasonable in scope, such duration, territory and/or
restricted activity, as the case may be, shall be redefined by consideration of
the reasonable concerns and needs of the Company such that the intent of the
Company, in consummating the transactions contemplated by the Agreement will not
be impaired and shall be enforceable to the fullest extent permissible under
applicable laws.

                  6.6 Developments.

                           6.6.1 If at any time or times during the Employee's
employment hereunder, he shall (either alone or with others) make, conceive,
create, discover or reduce to practice any invention, modification, discovery,
design, development, improvement, process, software program, work of authorship,
documentation, formula, data, technique, know-how, secret or intellectual
property right whatsoever or any interest therein (whether or not patentable or
registrable under copyright, trademark or

                                       13
<PAGE>   14

similar statutes or subject to analogous protection) (the "Developments") that
(i) relates to the business of the Company or any customer of or supplier to the
Company or any of the products or services being developed or sold by the
Company or which may be used in relation therewith, (ii) results from
responsibilities undertaken by the Employee on behalf of the Company, or (iii)
results from the use of premises or personal property (whether tangible or
intangible) owned, leased or contracted for by the Company, such Developments
and the benefits thereof are and shall immediately become the sole and absolute
property of the Company and its assigns, and the Employee shall promptly
disclose to the Company (or any persons designated by it) each such Development
and, as may be necessary to ensure the Company's ownership of such Developments,
Employee hereby assigns any rights (including, but not limited to, any
copyrights and trademarks) he may have or acquire in the Developments and
benefits and/or rights resulting therefrom to the Company and its assigns
without further compensation and shall communicate, without cost or delay, and
without disclosing to others the same, all available information relating
thereto (with all necessary plans and models) to the Company.

                           6.6.2 Upon disclosure of each Development to the
Company, the Employee agrees to, during his employment hereunder and at any time
thereafter, at the request and cost of the Company, sign, execute, make and do
all such deeds, documents, acts and things as the Company and its duly
authorized agents may reasonably require:

                  (i) to apply for, obtain, register and vest in the name of the
         Company alone (unless the Company otherwise directs) letters patent,
         copyrights, trademarks or other analogous protection in any country
         throughout the world and when so obtained or vested to renew and
         restore the same; and

                  (ii) to defend any opposition or other administrative
         proceedings in respect of such applications and any opposition
         proceedings or petitions or applications for cancellation or revocation
         of such letters patent, copyright or other analogous protection.

                           6.6.3 In the event the Company is unable, after
reasonable and good faith efforts, to secure Employee's signature on any letters
patent, copyright or trademark registration applications or other documents
regarding any legal protection relating to a Development, whether because of
Employee's physical or mental incapacity or for any other reason whatsoever,
Employee hereby irrevocably designates and appoints the Company and its duly
authorized officers and agents as his agent and attorney-in-fact, to act for and
in his behalf and stead to execute and file any such application or applications
or other documents and to do all other lawfully permitted acts to further the
prosecution and issuance of letters patent, copyright or trademark registrations
or other legal protection thereof with the same legal force and effect as if
executed by the Employee.

         7. ASSIGNMENT. The parties acknowledge that this Agreement has been
entered into due to, among other things, the special skills of Employee, and
agree that Employee may not assign any of his rights or delegate any of his
duties or obligations under this Agreement. The rights of Employee shall inure
to the benefit of his heirs and beneficiaries. The rights and obligations of
Company under this Agreement shall inure to the benefit of and shall be binding
upon the successors and assigns of the Company, provided that the Company may
not assign (by operations of law, change in control, or otherwise) any of its
rights or obligations hereunder without the prior written consent of the
Employee, except in connection with any merger or transfer of the Company or of
all or any substantial part of the business of the Company.

         8. NOTICES. All notices, requests, demands, and other communications
required or permitted hereunder shall be in writing and shall be deemed to have
been duly given if personally delivered or seven days after mailing if mailed,
first class, certified or registered mail, postage prepaid:

Any party may change the address to which notices, requests, demands, and other
communications shall be delivered or mailed by giving notice thereof to the
other party in the same manner provided herein.

         9. PROVISIONS SEVERABLE. If any provision or covenant, or any part
thereof, of this Agreement should be held by any court to be invalid, illegal or
unenforceable, either in whole or in part, such invalidity, illegality or
unenforceability shall not affect the validity, legality or enforceability of
the remaining provisions or covenants, or any part thereof, of this Agreement,
all of which shall remain in full force and effect.

         10. DISPUTE RESOLUTION.

                  10.1 In the event of any dispute, claim, question or
disagreement arising from or relating to this Agreement, the Note or the Pledge
or the breach of any of the foregoing, the Company and the Employee shall use
their best efforts to settle such dispute, claim, question or disagreement. To
this effect, the Company and the Employee shall consult and negotiate with each
other in good faith and attempt to reach a just and equitable solution
satisfactory to both the Company and the Employee. If the Company and the
Employee do not reach such solution within a period of 15 days after initiation
of such consultation and negotiation, such dispute, claim, question or
disagreement shall be submitted to non-binding mediation administered by the
American Arbitration Association under its Employment Mediation Rules before
resorting to arbitration, litigation or some other dispute resolution process.
Such non-binding mediation shall be conducted in Greenville County, South
Carolina. Each of the Company and the Employee shall bear its own costs and
expenses (including attorneys fees) and an equal share of the mediators' and
administrative fees of mediation. If such dispute, claim, question or
disagreement is not resolved within 45 days after initiation of mediation, then,
upon notice by either the Company or the Employee to the other, such dispute,
claim, question or disagreement shall be finally settled by binding arbitration
administered by the American Arbitration Association in accordance with its
National Rules for the Resolution of Employment Disputes, and judgment on the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof. Such arbitration shall be conducted in Greenville County, South
Carolina. The arbitration shall be conducted by a single arbitrator selected in
accordance with applicable rules of the American Arbitration Association. The
parties agree that the arbitrator shall have no power or authority to make
awards or issue orders of any kind except as expressly permitted by this
Agreement, the Note or the Pledge, as the case may be, and in no event shall the
arbitrator have the

                                       15
<PAGE>   16

authority to make any award that provides for punitive or exemplary damages or
consequential damages. The arbitrator shall award to the prevailing party, if
any, as determined by the arbitrator, all of its costs and fees. "Costs and
fees" means all reasonable pre-award expenses of the arbitration, including the
arbitrator's fees, administrative fees, travel expenses, out-of-pocket expenses
such as copying and telephone, court costs, witness fees and attorneys' fees.
The award of the arbitrator shall be in writing, signed by the arbitrator and
accompanied by a reasoned opinion which includes a breakdown as to specific
claims. During the period of the aforesaid negotiation, non-binding mediation
and arbitration, the Company and the Employee shall continue to comply fully
with their respective obligations under this Agreement (for example, the
Employee will continue to perform the Employee's duties and responsibilities to
the Company and the Company will continue to pay to the Employee his salary and
to provide to the Employee his benefits described in this Agreement), the Note
and the Pledge, as the case may be.

                  10.2 Types of Claims. All legal claims brought by any party
against the other party related to this Agreement, the employment relationship,
terms and conditions of employment, and/or termination from employment, the
Note, and/or the Pledge, are subject to this dispute resolution procedure. These
include, by way of example and without limitation, any legal claims based on
alleged discrimination or retaliation on the basis of race, sex, religion,
national origin, age or disability, whether based on state or federal law;
workers' compensation retaliation; defamation; invasion of privacy; infliction
of emotional distress and/or breach of an express or implied contract. The above
terms notwithstanding, any legal claim brought by Employee or Company for or
relating to workers' compensation, unemployment compensation benefits,
misappropriation of Company's trade secrets, breach or violation of provisions
of any confidentiality agreements or non-compete agreements, and claims alleging
status or membership with regard to any employment benefit plan are not subject
to this dispute resolution procedure.

         11. WAIVER. Failure of either party to insist, in one or more
instances, on performance by the other in strict accordance with the terms and
conditions of this Agreement shall not be deemed a waiver or relinquishment of
any right granted in this Agreement or of the future performance of any such
term or condition. No waiver shall be valid unless in writing signed by the
party sought to be bound. Time is of the essence with respect to performance
under this Agreement.

         12. REPRESENTATIONS. Employee agrees that this Agreement constitutes
the legal, valid and binding obligation of Employee, enforceable in accordance
with its terms. Employee further represents and warrants to Company that he is
subject to no agreement or obligation (including, without limitation, any
non-competition or confidentiality agreement) or bound by any contract with any
Person, corporation, or other entity that would prohibit him from entering into
or delivering this Agreement or taking the position described herein or in any
way interfere with the performance of his duties and obligations to Company
under this Agreement. Employee agrees to indemnify and hold harmless the Company
and its officers, directors, employees, managers, members, shareholders and
agents from and against any (1) claim (and the expenses associated therewith,
including without limitation reasonable attorney's fees) by a third party under
a non-competition, confidentiality or similar agreement or (2) any loss arising
as a result of Employee's breach of any of Employee's representations or
warranties contained in this Agreement, including the exhibits and other
attachments hereto.

         13. AMENDMENTS AND MODIFICATIONS. This Agreement may be amended or
modified only by a writing signed by all parties hereto. The parties hereby

<PAGE>   17

representations, promises, agreements, or understandings, written or oral,
relating thereto not contained herein shall be of any force or effect.

         14. GOVERNING LAW. The validity and effect of this agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of South Carolina, without giving effect to South Carolina's rules of conflicts
law, and regardless of the place or places of its physical execution or
performance.

         15. CAPTIONS. The captions contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

         16. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which taken together shall constitute one instrument.

         17. NO CONSTRUCTION AGAINST EITHER PARTY. In the event that there is
any dispute regarding the interpretation or construction of the provisions of
this Agreement, there shall be no presumption that any provision of this
Agreement is to be construed against either party hereto.

         18. BOARD APPROVAL. The Company represents and warrants to the Employee

                                 PROMISSORY NOTE

$749,997.50                                                       March 10, 2000

         For value received, George Michael Cassity ("Promisor") promises to pay
to the order of State Communications, Inc., a South Carolina corporation (the
"Company"), the aggregate principal sum of $749,997.50. This Note was issued
pursuant to and is subject to the terms of the Employment Agreement, dated as of
the date hereof, between the Company and Promisor (the "Employment Agreement").
Unless otherwise indicated herein, capitalized terms used in this Note have the
meaning set forth in the Employment Agreement.

         Interest shall accrue on a daily basis on the outstanding principal
amount of this Note at a rate equal to the lesser of (i) 8.12% per annum,
compounded annually, computed on the basis of a 360 day year and the actual
number of days elapsed or (ii) the highest rate permitted by applicable law, and
shall be payable annually in arrears.

         Payments of principal of, and accrued and unpaid interest under, this
Note shall be due and payable on the earlier of (i) the third anniversary of the
date hereof or (ii) sixty (60) days after the effective date of the termination
of Promisor's employment with the Company pursuant to the Employment Agreement
(the "Maturity Date"); provided however, that the Company may extend the
Maturity Date one or more times in its sole discretion by a period of one year
by providing written notice to the Promisor of such extension no later than 10
days prior to the then-existing Maturity Date.

         Payments of principal of, and accrued and unpaid interest under, this
Note shall be due and payable upon Promisor's receipt of proceeds from the
transfer, from time to time, of any Pledged Shares (as defined in the Pledge
Agreement between Promisor and the Company of even date herewith) in the full
amount of such proceeds (net of costs of sale and any taxes attributable
thereto) or such lesser amount as is necessary to pay the full amount of
outstanding principal of and accrued interest under this Note and for Promisor
to otherwise fully and finally discharge its obligations under this Note.
Promisor may, at his option, pay all or any portion of the principal of, and
accrued and unpaid interest under, this Note at any time and from time to time
prior to the maturity hereof without penalty or premium. Promisor may, at his
option, pay all or any portion of amounts due under this Note by from time to
time surrendering to the Company a portion of the Pledged Shares having a Fair
Market Value (as defined below) equal to the amount of such payment. Any payment
hereunder shall be applied first to pay accrued and unpaid interest under this
Note and second to reduce the outstanding principal amount of this Note.

         "Fair Market Value" means, with respect to the Pledged Shares, the
average of the closing prices of the sales of the Company's Series C Preferred
Stock, or any other security of the Company or any other entity which the
aforesaid Series C Preferred Stock is convertible into or exchanged for (the
"Stock") on all securities exchanges on which the Stock may at the time be
listed, or, if there have been no sales on any such exchange on any day, the
average of the highest bid and lowest asked prices on all such exchanges at the
end of such day, or, if on any day the Stock is not so listed, the average of
the representative bid and asked prices quoted in the NASDAQ System as of 4:00
p.m., New York time, or, if on any day the Stock is not quoted in the NASDAQ
System, the average of the highest bid and lowest asked prices on such day in
the domestic over-the-counter market as reported by the National Quotation
Bureau Incorporated, or any similar successor organization, in each such case
averaged over a period of 21 days consisting of the day as of which the Fair
Market Value is being determined and the 20 consecutive business days
immediately prior to such day. If at any time the Stock is not listed on any
securities exchange or quoted in the NASDAQ System or the over-the-counter
market, the Fair Market

                                       18
<PAGE>   19

Value shall be the fair value of such shares determined in good faith by the
Board of Directors of the Company.

         The amounts due under this Note are secured by a pledge of the Pledged
Shares. Any cash dividends declared and paid with respect to the Pledged Shares
shall be payable directly to the Company and shall be applied to reduce the
outstanding principal amount (and any interest thereon) of this Note and any
cash dividends paid to Promisor with respect to the Pledged Shares will be
promptly remitted to the Company and shall be applied to reduce the outstanding
principal amount (and any interest thereon) of this Note.

         In the event Promisor fails to pay any amounts due hereunder when due,
Promisor shall pay to the holder hereof, in addition to such amounts due, all
costs of collection, including reasonable attorneys fees.

         Promisor, or his successors and assigns, hereby waives diligence,
presentment, protest and demand and notice of protest, demand, dishonor and
nonpayment of this Note (other than notice of default with respect to matters
other than the non-payment of interest and/or principal), and expressly agrees
that this Note, or any payment hereunder, may be extended from time to time and
that the holder hereof may accept security for this Note or release security for
this Note, all without in any way affecting the liability of Promisor hereunder.

         The Company may not assign (by operation of law, change in control or
otherwise) any of its obligations or rights hereunder without the prior written
consent of the Promisor except in connection with any merger or transfer of all
or any substantial part of the business of the Company.

         Any failure by the Company to exercise any right hereunder shall not be
construed as a waiver of its right to exercise the same or any other right
hereunder at any other time.

         This Note and all rights hereunder shall be governed by the internal
laws, and not the laws of conflicts, of the State of South Carolina.

         IN WITNESS WHEREOF, this Promissory Note has been executed as of the
date first written above.

THIS CONTRACT IS SUBJECT TO ARBITRATION PURSUANT TO S.C. CODE SS. 15-48-10(2)

                             STOCK PLEDGE AGREEMENT

         THIS PLEDGE AGREEMENT is made as of March 10, 2000, between George
Michael Cassity ("Pledgor"), and State Communications, Inc., a South Carolina
corporation (the "Company").

         The Company and Pledgor are parties to an Employment Agreement of even
date herewith, pursuant to which Pledgor acquired and purchased 176,470 shares
of the Company's Series C Preferred Stock (the "Pledged Shares"), for an
aggregate purchase price of $749,997.50. The Company has allowed Pledgor to
purchase the Pledged Shares by delivery to the Company of a promissory note of
even date herewith (the "Note") in the aggregate principal amount of
$749,997.50. This Pledge Agreement provides the terms and conditions upon which
the Note is secured by a pledge to the Company of the Pledged Shares.

         NOW, THEREFORE, in consideration of the premises contained herein and
other good and valuable consideration the receipt and sufficiency of which are
hereby acknowledged, and in order to induce the Company to accept the Note as
payment for the Pledged Shares, Pledgor and the Company hereby agree as follows:

         1. Pledge. Pledgor hereby pledges to the Company, and grants to the
Company a security interest in, the Pledged Shares as security for the prompt
and complete payment when due of the unpaid principal of and interest on the
Note and full payment and performance of the obligations and liabilities of
Pledgor hereunder.

         2. Delivery of Pledged Shares. Upon the execution of this Pledge
Agreement, Pledgor shall deliver to the Company the certificate(s) representing
the Pledged Shares, together with duly executed forms of assignment sufficient
to transfer title thereto to the Company.

         3. Voting Rights; Cash Dividends. Notwithstanding anything to the
contrary contained herein, during the term of this Pledge Agreement until such
time as there exists a default in the payment of principal or interest on the
Note or any other default under the Note or hereunder, Pledgor shall be entitled
to all voting rights with respect to the Pledged Shares. Upon the occurrence of
and during the continuance of any such default, Pledgor shall no longer be able
to vote the Pledged Shares. During the term of this Pledge Agreement, all cash
dividends paid in respect of the Pledged Shares shall be paid to the Company and
applied by the Company to the outstanding principal amount of the Note and any
interest thereon.

         4. Stock Dividends; Distributions, etc. If, while this Pledge Agreement
is in effect, Pledgor becomes entitled to receive or receives any securities or
other property as an addition to, in substitution of, or in exchange for any of
the Pledged Shares (whether as a distribution in connection with any
recapitalization, reorganization or reclassification, a stock dividend or
otherwise), Pledgor shall accept such securities or other property on behalf of
and for the benefit of the Company as additional security for Pledgor's
obligations under the Note and shall promptly deliver such additional security
to the Company together with duly executed forms of assignment, and such
additional security shall be deemed to be part of the Pledged Shares hereunder.

--------------------

         (2) UNLESS THE UNITED STATES ARBITRATION ACT APPLIES.

                                       20
<PAGE>   21

         5. Default. If Pledgor defaults in the payment of the principal or
interest under the Note when it becomes due (whether upon demand, acceleration
or otherwise) or any other event of default under the Note or this Pledge
Agreement occurs, the Company may exercise any and all the rights, powers and
remedies of any owner of the Pledged Shares (including the right to vote the
shares and receive dividends and distributions with respect to such shares) and
shall have and may exercise without demand (other than notice of default with
respect to matters other than payment of interest and/or principal) any and all
the rights and remedies granted to a secured party upon default under the
Uniform Commercial Code of the State of South Carolina or otherwise available to
the Company under applicable law. Without limiting the foregoing, the Company is
authorized to sell, assign and deliver at its discretion, from time to time, all
or any part of the Pledged Shares at any private sale or public auction, on not
less than ten days written notice to Pledgor, at such price or prices and upon
such terms as the Company may deem advisable. Pledgor shall have no right to
redeem the Pledged Shares after any such sale or assignment. At any such sale or
auction, the Company may bid for, and become the purchaser of, the whole or any
part of the Pledged Shares offered for sale. In case of any such sale, after
deducting the costs, attorneys' fees and other expenses of sale and delivery,
the remaining proceeds of such sale shall be applied to the principal of and
accrued interest on the Note; provided that after payment in full of the
indebtedness evidenced by the Note, the balance of the proceeds of sale then
remaining shall be paid to Pledgor and Pledgor shall be entitled to the return
of any of the Pledged Shares remaining in the hands of the Company. Pledgor
shall be liable for any amount of the outstanding principal and accrued interest
on the Note for any deficiency if the remaining proceeds are insufficient to pay
the indebtedness under the Note in full, including the fees of any attorneys
employed by the Company to collect such deficiency.

         6. Costs and Attorneys' Fees. All costs and expenses (including
reasonable attorneys' fees) incurred in exercising any right, power or remedy
conferred by this Pledge Agreement or in the enforcement thereof, shall become
part of the indebtedness secured hereunder and shall be paid by Pledgor or
repaid from the proceeds of the sale of the Pledged Shares hereunder.

         7. Payment of Indebtedness and Release of Pledged Shares. Upon payment
in full of the indebtedness evidenced by the Note, the Company shall surrender
the Pledged Shares and any additional security to Pledgor together with all
forms of assignment.

         8. No Other Liens; No Sales or Transfers. Pledgor hereby represents and
warrants that he has good and valid title to all of the Pledge Shares, free and
clear of all liens, security interests and other encumbrances (except as
contemplated herein and except as otherwise for the benefit of the Company), and
Pledgor hereby covenants that, until such time as all of the outstanding
principal of and interest on the Note has been repaid, Pledgor shall not (i)
create, incur, assume or suffer to exist any pledge, security interest,
encumbrance, lien or charge of any kind against the Pledged Shares or Pledgor's
rights as a holder thereof, other than pursuant to this Agreement, or (ii) sell
or otherwise transfer any Pledged Shares or any interest therein, provided that,
notwithstanding the foregoing, (a) the Pledgor shall be entitled to surrender
any portion of the Pledged Shares to the Company as payment on the Note, as
described in the Note, and (b) the Pledgor shall be entitled, from time to time,
to sell or otherwise transfer any portion of the Pledged Shares so long as the
Pledgor ensures that the proceeds from any such sale are delivered to the
Company as payment on the Note, as described in the Note.

         9. Further Assurances. Pledgor agrees that at any time and from time to
time upon the written request of the Company, Pledgor shall execute and deliver
such further documents (including UCC financing statements) and do such further
acts and things as the Company may reasonably request in order to effect the
purposes of this Pledge Agreement.

         10. Severability. Any provision of this Pledge Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such

                                       21
<PAGE>   22

prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         11. No Waiver; Cumulative Remedies. The Company shall not by any act,
delay, omission or otherwise be deemed to have waived any of its rights or
remedies hereunder, and no waiver shall be valid unless in writing, signed by
the Company, and then only to the extent therein set forth. A waiver by the
Company of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Company would otherwise have
on any future occasion. No failure to exercise nor any delay in exercising on
the part of the Company, any right, power or privilege hereunder shall preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege. The rights and remedies herein provided are cumulative and may be
exercised singly or concurrently, and are not exclusive of any rights or
remedies provided by law.

         12. Waivers, Amendments; Applicable Law. None of the terms or
provisions of this Pledge Agreement may be waived, altered, modified or amended
except by an instrument in writing, duly executed by the parties hereto. This
Agreement and all obligations of the parties hereunder shall together with the
rights and remedies of the parties hereunder, be binding upon and inure to the
benefit of the parties hereto and their respective heirs, beneficiaries,
successors and assigns, provided that no party hereto may assign (by operation
of law, change in control or otherwise) any of its rights or obligations
hereunder without the prior written consent of the other party hereto, except in
connection with any merger or transfer of the Company or of all or any
substantial part of the business of the Company. This Pledge Agreement shall be
governed by, and be construed to interpreted in accordance with, the laws of the
State of South Carolina.

         13. No Construction Against Either Party. In the event that there is
any dispute regarding the interpretation or construction of the provisions of
this Pledge Agreement, there shall be no presumption that any provision of this
Pledge Agreement is to be construed against either party hereto.

         14. Release of Pledged Shares. Upon each payment of any principal of
the Note, there shall be released from the terms of this Pledge Agreement the
number of shares of the Pledged Shares held by the Company pursuant to this
Pledge Agreement in excess of the number of shares of the Pledged Shares held by
the Company pursuant to this Pledge Agreement at that time equal to the
outstanding principal balance of the Note at that time divided by the Fair
Market Value (as defined in the Note). As such shares of the Pledged Shares are
released, the Company shall promptly surrender to the Pledgor, without recourse
or warranty, all certificates evidencing and stock powers in respect of such
released shares of the Pledged Shares.

                  IN WITNESS WHEREOF, this Pledge Agreement has been executed as
of the date first written above.

         termination for cause which notice shall specify in reasonable detail
         specific facts regarding any such assertion, (2) such written notice is
         provided to the Employee a reasonable time before the Board meets to

         of the Company. The unwillingness of the Employee to accept any or all

         If any provision of this Section 4.5 cannot, in whole or in part, be
implemented and carried out under the terms of the applicable compensation,

                           per year for discretionary expenses.

         5.6 Vacation. Employee shall be entitled to an annual vacation of not
more than three (3) weeks. Scheduling of such vacation shall be with the
reasonable consent of the Company.

         5.7 Stock Purchase and Loan. The Company shall use its best efforts to
allow Employee to purchase up to 35,000 shares of Series C Convertible Preferred
Stock in the Company's current offering of up to 4,214,703 shares of Series C
Convertible Preferred Stock (expected to be consummated in March 2000), such
purchase to be at a price of $4.25 per share and on the same terms and
conditions applicable to other purchasers in such offering. To this end, Company
shall extend a loan to Employee on March 15, 2000 in the amount of $148,750
(evidenced by a Promissory Note in the form attached hereto). Such loan bears
simple interest at the rate of 10% per year, and the principal and interest on
such loan shall be due and payable on March 15, 2003. Employee shall pay
interest only on each anniversary of the Promissory Note until maturity.

         5.8 Stock Options. Simultaneous to the execution of this Agreement, the
Company shall grant to Employee options to purchase 250,000 shares pursuant to
the Stock Option Agreement attached hereto.

6. Gross-Up of Payments. It is the intention of the parties that:

          (i) the net amount of all Termination Payments retained by the
Employee after deduction for and payment of all applicable federal, state and
local taxes (the "Withholding Taxes") payable by or on behalf of the Employee
shall be equal to the gross amount of the Termination Payments without regard to
any such deductions or payments (the "Net Termination Payments") and

         (ii) the net amount of all other payments or benefits received or to be
received by the Employee

                                  Page 6 of 12
<PAGE>   7

from the Company or one of its benefit plans as a direct or indirect result of
or in connection with a Change in Control or in connection with Termination
within one year of a Change in Control, from whatever source other than a
Termination Payment (the "Other Payments"), that are or become subject to the
tax (the "Excise Tax") imposed by Section 4999 of the Code, shall be equal to
the gross amount of the Other Payments without regard to deduction or payment or
any such Excise Tax.

         Accordingly, the Termination Payments otherwise payable hereunder shall
be increased by an amount of cash (the "Withholding Gross-Up Payment") equal to
all Withholding Taxes payable by or on behalf of the Employee in respect of the
Termination Payments, including any Withholding Taxes as may be due in respect
of such additional amounts to be paid pursuant to this sentence as will result
in the Employee actually retaining an amount equal to the Net Termination
Payments. In addition, if the sum of the Termination Payments, the Withholding
Gross-Up Payment and the Other Payments (the "Total Payments") are or become
subject to the Excise Tax, the Company shall pay the Employee within 30 days of
the termination date an additional cash amount (the "Excise Gross-Up Payment")
such that the net amount actually retained by the Employee, after deduction for
or payment of any Excise Tax on the Total Payments and the sum of any
Withholding Taxes upon the payment provided by this sentence shall be equal to
the Total Payments (the "Net Total Payments"). For the purposes of determining
whether any of the Total Payments will be subject to the Excise Tax and the
amount of such Excise Tax, the following shall apply:

         6.1 All "excess parachute payments" within the meaning of Section
280G(b)(1) of the Code shall be treated as subject to the Excise Tax, unless, in
the opinion of tax counsel selected by the Company's independent auditors and
acceptable to the Employee, such other payments or benefits (in whole or in
part) described in clause (a) above do not constitute parachute payments or such
excess parachute payments (in whole or in part) represent reasonable
compensation for services actually rendered within the meaning of Section
280(G)(b)(4) of the Code;

         6.2 the amount of the Termination Payments which shall be treated as
subject to the Excise Tax shall be equal to the lesser of:

                  (i) the total amount of the Termination Payments; and

                  (ii) the amount of excess parachute payments within the
         meaning of Sections 280G(b)(1) and (4) (after applying Sections 6.1 and
         6.2 above)

         6.3 the value of any non-cash benefits or any deferred payment or
benefit shall be determined by the Company's independent auditors in accordance
with the principles of Sections 280G(d)(3) and (4) of the Code; and

         6.4 the Employee shall be deemed to pay federal income taxes, and state
and local income taxes in the state and locality of the Employee's residence on
the date of Termination, at the highest marginal rate of income taxation in
effect in the calendar year in which the Gross-Up Payment is to be made, net of
the maximum reduction in federal income taxes which could be obtained from
deduction of such state and local income taxes.

         Provided, that in the event the Excise Tax or Withholding Taxes are
subsequently determined to be less than the amounts taken into account hereunder
at the time of the payment of the Withholding Gross-Up Payments or the Excise
Tax Gross-Up Payment, the Employee shall repay the Company the portion of such
payments attributable to such reduction, or in the event that the Excise Tax or
the Withholding Taxes are subsequently determined to exceed the amount taken
into account hereunder at the time of the

                                  Page 7 of 12
<PAGE>   8

payment of the Withholding Gross-Up Payment or the Excise Tax Gross-Up Payment
(including by reason of any payment the existence or amount of which cannot be
determined at the time of such payments), the Company shall make an additional
Gross-Up Payment in respect of such excess, in each case, payment to be made
within 30 days after the final determination of the amount of the reduction or
excess, as the case may be, together with interest thereon at the rate provided
in Section 1274(b)(2)(B) of the Code.

7. Confidential Information. Employee acknowledges that the proprietary
information, observations and data obtained by Employee while employed by the
Company concerning the business or affairs of the Company or any affiliate or
subsidiary thereof ("Confidential Information") is the property of the Company.
Therefore, Employee agrees not to disclose to any unauthorized person or use for
the Employee's account any Confidential Information without the prior written
consent of the Company. Upon request, Employee shall deliver to the Company at
the termination of this Employment Agreement, or at any other time the Company
may request, all memoranda, notes, plans, records, reports and other documents
(and copies thereof) relating to the Confidential Information or the business of
the Company, subject to the provisions of paragraph 7 hereof. The provisions of
this paragraph 7 shall not apply to the following:

         a. information that is part, or becomes part, of the public domain,
         through no act or omission of Employee;

         b. information that was already known to Employee at the time of its
         disclosure hereunder, including without limitation information gained
         by virtue of Employee's past experience and know-how, but excluding
         information gained as a result of his past representation of the
         Company as one of its outside attorneys;

         c. information that, subsequent to its disclosure hereunder, is
         obtained by Employee from a third party who rightfully possesses such
         information and has no obligation to maintain its confidentiality; and

         d. information that is developed through the independent research of
         Employee, without any reliance upon or use of information disclosed
         hereunder.

         The obligation not to disclose Confidential Information, as set forth
herein, is not intended to, nor shall it prohibit, Employee, consistent with the
Code of Professional Responsibility, from disclosing Confidential Information,
or parts thereof, pursuant to a lawfully issued subpoena, court order, statute
or regulations compelling such divulgence, provided that Employee gives
reasonable notice to the Company in advance of such divulgence so that the
Company may seek to quash the subpoena, obtain a protective order, or take other
appropriate measures under such circumstances and the Employee discloses only
the minimum necessary to comply with such subpoena, court order, statute or
regulation.

8. Assignment. The parties acknowledge that this Agreement has been entered into
due to, among other things, the special skills of Employee, and agree that
Employee may not assign any of her rights or delegate any of her duties or
obligations under this Agreement. The rights and obligations of Company under
this Agreement shall inure to the benefit of and shall be binding upon the
successors and assigns of the Company.

9. Notices. All notices, requests, demands, and other communications required or

10. Provisions Severable. If any provision or covenant, or any part thereof, of
this Agreement should be held by any court to be invalid, illegal or
unenforceable, either in whole or in part, such invalidity, illegality or
unenforceability shall not affect the validity, legality or enforceability of
the remaining provisions or covenants, or any part thereof, of this Agreement,

11.  Dispute Resolution.

         11.1 Mediation. If a dispute arises out of or in any way relates to
this Agreement or Employee's employment, and if the dispute cannot be settled
through negotiation, the parties agree first to try in good faith to settle the
dispute by mediation before resorting to arbitration, litigation, or some other
formal dispute resolution procedure. Any such dispute shall be submitted to a
mediator selected by mutual agreement of the parties. Unless the parties agree
to an alternative arrangement, the mediator's fee and expenses shall be equally
divided between the parties.

         11.2 Arbitration. Should any dispute arising out of or in any way
relating to this Agreement or Employee's employment or the termination of
Employee's employment not be resolved by negotiation or mediation, the parties
agree to waive their right to a jury trial and agree to submit the dispute to
arbitration. Unless otherwise provided herein, the arbitration shall be
conducted by a single arbitrator in accordance with the National Rules for the
Resolution of Employment Disputes published by the American Arbitration
Association. The arbitration shall be conducted in Greenville County, South
Carolina. The arbitrator shall be selected by mutual agreement of the parties.
If the parties cannot agree on an arbitrator within thirty (30) days after
written request for arbitration is made by one party to the controversy, a
neutral arbitrator shall be appointed according to the procedures set forth in
the American Arbitration Association National Rules for the Resolution of
Employment Disputes. In rendering the award, the arbitrator shall have the
authority to resolve only the legal dispute between the parties, shall not have
the authority to abridge or enlarge substantive rights or remedies available
under existing law, and shall determine the rights and obligations of the
parties according to the substantive and procedural laws of South Carolina. In
addition, the arbitrator's decision and award shall be in writing and signed by
the arbitrator, and accompanied by a written concise explanation of the basis of
the award. The award rendered by the arbitrator shall be final and binding, and
judgment on the award may be entered in any court having

                                  Page 9 of 12
<PAGE>   10

jurisdiction thereof. The arbitrator is authorized to award any party a sum
deemed proper for the time, expense, and trouble of arbitration, including
arbitration fees and attorneys' fees.

         11.3 Types of Claims. All legal claims brought by Employee against
Company related to this Agreement, the employment relationship, terms and
conditions of employment, and/or termination from employment are subject to this
dispute resolution procedure. These include, by way of example and without
limitation, any legal claims based on alleged discrimination or retaliation on
the basis of race, sex, religion, national origin, age or disability, whether
based on state or federal law; workers' compensation retaliation; defamation;
invasion of privacy; infliction of emotional distress and/or breach of an
express or implied contract. The above terms notwithstanding, any legal claim
brought by Employee or Company for or relating to workers' compensation,
unemployment compensation benefits, breach, violation or misappropriation of
Company's trade secrets, provisions of any confidentiality agreements or
noncompete agreements, and claims alleging status or membership with regard to
any employment benefit plan are not subject to this dispute resolution
procedure.

12. Waiver. Failure of either party to insist, in one or more instances, on
performance by the other in strict accordance with the terms and conditions of
this Agreement shall not be deemed a waiver or relinquishment of any right
granted in this Agreement or of the future performance of any such term or
condition. No waiver shall be valid unless in writing signed by the party sought
to be bound.

13. Company and Employee Representations. Employee represents and warrants to
Company that other than her expired agreement with her former employer, she is
subject to no agreement or obligation, which includes any non-competition or
confidentiality agreement. Employee agrees to hold Company and its officers,

any claim (and the expenses associated therewith) arising from a breach of this
warranty and representation.

14. Amendments and Modifications. This Agreement may be amended or modified only
by a writing signed by other parties hereto. The parties hereby agree that this

the Employee by the Company not contained herein shall be of any force or
effect.

or after her employment with Company, any documents, including applications for
patents and assignments, necessary or desired by Company. Employee will
cooperate with the filing and prosecution of any such patent applications
whenever Company so requests without further compensation. Employee attaches
hereto a complete list of all inventions that Employee made or conceived prior
to her employment by Company, if any exist, and Company agrees that these
inventions shall be excluded from this Agreement.

16. Governing Law. The validity and effect of this Agreement shall be governed
by and construed and enforced in accordance with the laws of the State of South
