     Agreement are strictly confidential and Client agrees not to knowingly or
     willfully divulge this information to any other Client or potential Client
     of Center.

b.   The Monthly Office Charge is based on the value of the use of the Premises
     and services to be used by ____ person(s) only. If more than said number of
     person(s) regularly use the Premises or services, the Monthly Office Charge

     to, and simultaneous with, any other amounts payable under this Agreement,
     a sum equal to the aggregate of any municipal, county, state, or federal

     any taxes commonly referred to as income, estate or inheritance taxes.

5. Refundable Retainer.

a.   Client will deposit with Center on file, in good or certified funds, as a
     non-interest bearing refundable retainer. Center may use the refundable
     retainer to cure any default of Client under this Agreement, to restore the
     Premises, including any and all furniture, fixtures and equipment, provided
     by Center to its original condition and configuration, reasonable wear and
     tear excepted, to pay for repairs to any damage to the Premises, Facility
     and/or Building, caused by Client or Client's guests, or to pay any Monthly
     Office Charge or other charges that Client owes Center at or prior to the
     expiration of the Term of this Agreement.

b.   The refundable retainer (less any sums used by Center in accordance with
     the terms and conditions of this Agreement) will be returned within sixty
     (60) days after the termination of any services rendered or expiration of
     the Term. Client may not direct or request that the refundable retainer be
     applied in lieu of the final payment(s) of Monthly Office Charge or service
     charges under this Agreement.

     In the event that Center applies any of the refundable retainer deposited
     pursuant to this Agreement, Center will have the right to charge the
     Client, and Client will pay, in addition to any Monthly Office Charge, such
     sums as are necessary to cause the refundable retainer to be returned to
     its entire original amount.

6. Services.

a.   Provided Client is not in default of this Agreement, Center will make
     available certain services to Client as more particularly described in
     Paragraph 1. Charges for such services will be included as part of the
     Monthly Charge as described in Schedule A.

b.   Client shall pay a monthly amount equal to $120.00 for a monthly base
     service package (the "Monthly Base Service Package"). The Monthly Base
     Service Package will entitle the Client to receive upon request a monthly
     clerical and/or word processing services from the Center valued at $120 per
     month.

c.   In addition to the Monthly Base Service Package, upon request, Center will
     make available to Client additional services as Center may make generally
     available, the charges for which will be established as per Center's then
     published rates as determined by Center. Payment for these services will be
     subject to the same terms and conditions as those governing the payment of
     the Monthly Office Charge. Center will have no obligation to provide such
     services if Client is in default of this Agreement or if the anticipated
     charges exceed the amount of the refundable retainer. When providing
     services to Client that involve third parties, Center will have the right
     to require Client to pay, or to reimburse Center for, the fees and expenses
     of such third party in advance.

7. Telephone Services.

a.   Provided Client is not in default of this Agreement, Center will make
     available to Client a telecommunications package, the charges for which
     will be established as per Center's then scheduled rates as determined by
     Center. Payment for these services will be subject to the same terms and
     conditions as those governing the payment of the Monthly Office Charge. All
     telephone numbers used by Client will remain at all times the property of
     Center and Client will acquire no rights in the components of the
     telecommunications package whatsoever.

b.   Client hereby agrees to indemnify, hold harmless and to reimburse Center
     for all charges associated with (1) any toll fraud traceable to
     telecommunications services provided by Center to Client including, but not
     limited to, unauthorized use of calling cards or telephone lines, and (2)
     any advertising costs of Client involving the assigned telephone numbers
     including, without limitation, yellow pages advertising, it being
     understood that Center is under no obligation to procure such advertising
     and that any such advertising by Client is subject to the Operating
     Standards.

c.   It is expressly acknowledged and agreed that Center will be the sole and
     exclusive provider of telecommunication services to Client. Client hereby
     agrees and covenants that it will not use any other telephone service or
     telephone carrier to provide it service in the Premises.

d.   Center shall not be liable for any interruption or error in the performance
     of its services to Client under this Paragraph "7." Client waives any
     recourse against Center arising from the provision of such services,
     including, without limitation, any claim of business interruption or for
     any indirect, incidental, special, consequential or punitive damages,
     except for claims arising out of willful misconduct by Center.

8. Limitation of Liability/Insurance.

a.   Client will indemnify and hold harmless Center from and against any loss,
     damage, injury, liability or expense to or of person or property occasioned
     by or resulting from any willful misconduct or grossly negligent act on the
     part of Client or Client's Users. Center will not be liable to Client or to
     any other person on account of loss, damage or theft to any business or
     personal property of Client. Center will not be liable for any loss,
     damage, injury, liability or expense to or of person or property except as
     may result from Center's willful misconduct or grossly negligent acts.
     Center will indemnify and hold harmless Client from and against any loss,
     damage, injury, liability or expense to or of person or property occasioned
     by or resulting from any willful misconduct or grossly negligent act on the
     part of the Center, its agents, employees, or invitees, or persons
     permitted on the Premises by Center.

b.   Center will not be liable for any claim of business interruption or for any
     indirect, incidental, special, consequential exemplary or punitive damages
     arising out of any failure to furnish any service or facility, any error or
     omission with respect thereto, or any delay or interruption of same.
     Neither Center nor any of its agents, employees, officers or directors will
     be deemed to be making any representations or warranties, whether express
     or implied, as to the ability of any systems, including, without
     limitation, computer and electronic based equipment, relating to the
     Building, Facility or Premises or to any services to be provided hereunder
     to process date fields relating to the Year 2000 nor will any of them be
     liable for the failure of such systems to process such date fields.
     Center's liability under this Agreement will in no event exceed the amount
     paid by Client for the services for which the claim arose. The parties
     agree to the allocation of risk contained herein.

c.   Client will, prior to the Commencement Date of this Agreement provide
     Center with a certificate of insurance evidencing General/Public Liability
     coverage with liability limits of not less than One Million Dollars
     ($1,000,000.00) per occurrence for Bodily Injury and/or Property Damage
     Liability and One Hundred Thousand Dollars ($100,000.00) per occurrence for
     Fire/Legal Liability. Said insurance coverage will remain in force during
     the Term of this Agreement. VANTAS International Incorporated and Vantas
     Corporate Center, Inc. will be named as an additional named insured on each
     of these policies. Client agrees that failure by Client to provide such
     coverage increases VANTAS's risk of loss and may increase VANTAS's cost of
     insurance. Should Client fail to provide the Certificate of Insurance,
     VANTAS may charge, and Client shall pay, a monthly fee of forty dollars
     ($40.00) for the first office and twenty dollars ($20.00) for each
     additional office occupied under this Agreement as compensation for the
     additional risk and/or costs incurred by VANTAS. Client's failure to
     provide or maintain such insurance will not reduce or otherwise alter
     Client's liability or responsibility to pay any judgment rendered against
     Client for any liability or damages. All insurance required to be
     maintained by Client include a waiver of subrogation in favor of Center and
     the landlord under the Main Lease. Center will not have any obligation to
     maintain insurance for Client's benefit.

d.   The provisions of this Paragraph 8 will survive the expiration or earlier
     termination of the term of this Agreement.

The Operating Standards attached to this Agreement as Schedule A are hereby made
an integral part of this Agreement. Client, its employees, agents, guests,
invitees, visitors and/or any other persons caused to be present in and around
the Premises by the Client ("Client's Users") will perform and abide by the
Operating Standards then in effect.

an employee of Center or any person who has been an employee of Center within
six months prior to the time such person is hired by Client, Client will be

employee, at the rate last paid that employee by Center. The provisions of this
paragraph will survive the Teen of this Agreement.

     of the Premises.

     Main Lease.

     pay the amount of such deficiency, plus the expenses of entering into such
     other Service Agreement relating to the Premises, immediately in one lump
     sum, to Center upon demand and/or, at Center's option, as such obligations
     accrue hereunder.

     incurs attorney's fees and/or costs of collection or of ensuring
