7. TRADE SECRETS, CONFIDENTIAL INFORMATION AND NONSOLICITATION

        7.1 During the term of her employment, Employee will have access to, and
become familiar with, various trade secrets and proprietary and confidential
information of the Employer ("Confidential Information"), including customer
names or lists, pricing structures, customer order or preference information,
marketing and strategic plans, financial information, training manuals,
operating manuals and sales techniques. Employee acknowledges that the
Employer's business requires strict confidentiality and secrecy in connection
with its practices, procedures, and methods of operation. Employee further
acknowledges that information of this nature is confidential and is owned, and
shall continue to be owned, exclusively by the Employer. During the Employment
Period and for three years after employment terminates, except as reasonably
necessary to perform her duties and responsibilities as an employee of the
Employer, Employee shall not use the Confidential Information for any purpose or
divulge the Confidential Information to any person or entity other than the
Employer, unless the Confidential Information already has become generally known
to the public (except to the extent that such information has become generally
known to the public by means of Employee's breach of this Agreement).

        7.2 Except as reasonably necessary to perform her duties and
responsibilities as an employee of the Employer, Employee shall not remove from
the Employer's office any of the Employer's books, records, documents, customer
lists, or any copies (in any form) of documents without the Employer's written
permission. Employee shall not make any copies of these books, records,
documents, or customer lists for use outside of the Employer's office, except as
specifically authorized in writing by the Employer. All such documents and
copies in the possession or control of Employee must be returned to the Employer
by Employee immediately upon the termination of her employment.

        7.3 Employee agrees that, during her employment and for a period of one
year immediately following the termination of employment, except to the extent
necessary to carry out her duties and responsibilities as an employee, she will
not, directly or indirectly, for himself or on behalf of any other person or
entity, solicit, divert away, take away or attempt to solicit, divert or take
away, any Customer of the Employer for the purpose of selling or providing to
such Customer, provided the Employer is then still engaged in the sale or
provision of that type of good or service. For purposes of this Agreement, the
term "Customer" means any individual or entity to whom the Employer provided
goods or services and with whom Employee had material contact during the twelve
months prior to the termination of her employment.

        7.4 Employee agrees that she will not, during her employment and for a
period of one year immediately thereafter, solicit or induce, or attempt to
solicit or induce, any employee or contractor of the Employer to terminate his
relationship with the Employer and/or to enter into an employment or agency
relationship with Employee or with any other person or entity with whom Employee
is affiliated in any way.

        7.5 Employee acknowledges and agrees that the covenants and promises
contained in this Section 7 are a reasonable and necessary means of protecting
and preserving the Employer's goodwill and its interest in the confidentiality
and/or proprietary value of its trade secrets and confidential information.
Employee further acknowledges that said covenants and promises are a reasonable
and necessary means of protecting the Employer from unfair competition by
Employee. Employee agrees that any breach of these covenants or promises will
leave the Employer with no adequate remedy at law and will cause the Employer to
suffer irreparable damage and injury. Employee further agrees that any breach of
these covenants and promises will entitle the Employer to injunctive relief in
any court of competent jurisdiction without the necessity of posting any bond.
Employee also agrees that any such injunctive relief shall be in addition to any
damages that may be recoverable by the Employer as a result of such breach.
