         I have read and understand the terms and conditions on the reverse side
         and I agree to be bound by those terms and conditions.

Additional Terms:

         HQ agrees that client may occupy office #11; 12; 13; and 17 before the
         commencement of said agreement, for the prorated amount for the period.
         During this period, the Client shall be subject to all of the terms and
         conditions contained in this Agreement.


                              TERMS AND CONDITIONS


1. OFFICE ACCESS. As a client you have a license to use the office(s) assigned
   to you. You also have shared use of common areas in the center. Your office
   comes with standard office furniture. You have access to your office(s)
   twenty-four (24) hours a day, seven (7) days a week. Our building provides
   office cleaning, maintenance services, electric heating and air conditioning
   to the center during normal business hours as determined by the landlord for
   the building.
     We reserve the right to relocate you to another office in the center from
   time to time. If we exercise this right it will only be to an office of equal
   or larger size and configuration. This relocation is at our expense.
     We reserve the right to show the office(s) to prospective clients and will
use reasonable efforts not to disrupt your business.

2. SERVICES. In addition to your office, we provide you with certain services on
   an as requested basis. The fee schedule for these services is available upon
   request. The fees are charged to your account and are payable on the service
   fee payment date listed on the reverse side of this agreement. You agree to
   pay all charges authorized by you or your employees. The fee schedule is
   updated from time to time.
     HQ Global Workplaces (HQ) and vendors designated by HQ are the only service
   providers authorized to provide services in the center. You agree that
   neither you nor your employees will solicit other clients of the center to
   provide any service provided by HQ or its designated vendors, or otherwise.
     In the event you default on your obligations under this agreement, you
   agree that HQ may cease to provide any and all services including telephone
   services without resort to legal process.

3. PAYMENTS. You agree to pay the fixed and additional service fees and all
   applicable sales or use taxes on the payment dates listed on the reverse side
   of this agreement. If you dispute any portion of the charges on your bill,
   you agree to pay the undisputed portion on the designated payment date. You
   agree that charges must be disputed within ninety (90) days or you waive your
   right to dispute such charges. You may be charged a late fee for any late
   payments.
     When you sign this agreement you are required to pay your fixed fee, set up
   fees and a refundable retainer. The refundable retainer will not be kept in a
   separate account from other funds of HQ and no interest will be paid to you
   on this amount. The refundable retainer may be applied to outstanding charges
   at any time at our discretion. We have the right to require that you replace
   retainer funds that we apply to your charges. At the end of the term of this
   agreement, if you have satisfied all of your payment obligations, we will
   refund you this retainer within forty-five (45) days.

4. OUR LIMITATION OF LIABILITY. You acknowledge that due to the imperfect nature
   of verbal, written and electronic communications, neither HQ nor HQ's
   landlord or any of their respective officers, directors, employees,
   shareholders, partners, agents or representatives shall be responsible for
   damages, direct or consequential, that may result from the failure of HQ to
   furnish any service, including but not limited to the service of conveying
   messages, communications and other utility or services. Your sole remedy and
   HQ's sole obligation for any failure to render any service, any error or
   omission, or any delay or interruption of any service, is limited to an
   adjustment to your bill in an amount equal to the charge for such service for
   the period during which the failure, delay or interruption continues.
     WITH THE SOLE EXCEPTION OF THE REMEDY DESCRIBED ABOVE, CLIENT EXPRESSLY AND
   SPECIFICALLY AGREES TO WAIVE, AND AGREES NOT TO MAKE, ANY CLAIM FOR DAMAGES,
   DIRECT OR CONSEQUENTIAL, INCLUDING WITH RESPECT TO LOST BUSINESS OR PROFITS,
   ARISING OUT OF ANY FAILURE TO FURNISH ANY SERVICE, ANY ERROR OR OMISSION WITH
   RESPECT THERETO, OR ANY DELAY OR INTERRUPTION OF SERVICES. HQ DISCLAIMS ANY
   WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

5. LICENSE AGREEMENT. THIS AGREEMENT IS NOT A LEASE OR ANY OTHER INTEREST IN
   REAL PROPERTY. IT IS A CONTRACTUAL ARRANGEMENT THAT CREATES A REVOCABLE
   LICENSE. We retain legal possession and control of the center and the office
   assigned to you. Our obligation to provide you space and services is subject
   to the terms of our lease with the building. This agreement terminates
   simultaneously with the termination of our lease or the termination of the
   operation of our center for any reason. As our client you do not have any
   rights under our lease with our landlord. When this agreement is terminated
   because the term has expired or otherwise, your license to occupy the center
   is revoked. You agree to remove your personal property and leave the office
   as of the date of termination. We are not responsible for property left in
   the office after termination.

6. DAMAGES AND INSURANCE. You are responsible for any damage you cause to the
   center or your office(s) beyond normal wear and tear. We have the right to
   inspect the condition of the office from time to time and make any necessary
   repairs.
     You are responsible for insuring your personal property against all risks.
   You have the risk of loss with respect to any of your personal property. You
   agree to waive any right of recovery against HQ, its directors, officers and
   employees for any damage or loss to your property under your control. All
   property in your office(s) is understood to be under your control.
7. DEFAULT. You are in default under this agreement if; 1) you fail to abide by
   the rules and regulations of the center, a copy of which has been provided to
   you; 2) you do not pay your fees on the designated payment date and after
   written notice of this failure to pay you do not pay within five (5) days;
   and 3) you do not comply with the terms of this agreement. If the default is
   unrelated to payment you will be given written notice of the default and you
   will have ten (10) days to correct the default.

8. TERMINATION. You have the right to terminate this agreement early; 1) if your
   mail or telecommunications service or access to the office(s) is cut for a
   period of ten (10) concurrent business days; or 2) in connection with a
   transfer to another center in the HQ network.
     HQ has the right to terminate this agreement early; 1) if you fail to
   correct a default or the default cannot be corrected; 2) without opportunity
   to cure if you repeatedly default under the agreement; or 3) if you use the
   center for any illegal operations or purposes.

9. RESTRICTION ON HIRING. Our employees are an essential part of our ability to
   deliver our services. You acknowledge this and agree that, during the term of
   your agreement and for six (6) months afterward, you will not hire any of our
   employees. If you do hire one of our employees, you agree that actual damages
   would be difficult to determine and therefore you agree to pay liquidated
   damages in the amount of one-half of the annual base salary of the employee
   you hire. You agree that this liquidated damage amount is fair and
   reasonable.

10. MISCELLANEOUS.
A. All notices are to be in writing and may be given by registered or certified
   mail, postage prepaid, overnight mail service or hand delivered with proof of
   delivery, addressed to HQ or client at the address listed on the reverse side
   of this agreement.
B. You acknowledge that HQ will comply with the U.S. Postal Service regulations
   regarding client mail. Upon termination of this agreement, you must notify
   all parties with whom you do business of your change of address. You agree
   not to file a change of address form with the postal service. Filing of a
   change of address form may forward all mail addressed to the center to your
   new address. In addition, all telephone and facsimile numbers and IP
   addresses are the property of HQ. These numbers will not be transferred to
   you at the end of the term. For a period of thirty (30) days after the
   expiration of this agreement, HQ will provide your new telephone number and
   address to all incoming callers and will hold or forward your mail, packages,
   and facsimiles at no cost to you. After thirty days (30) you may request the
   continuation of this service at your cost. Business Access clients must pay
   for the additional five (5) months of mail forwarding required by the USPS
   regulations.
C. In the event a dispute arises under this agreement you agree to submit the
   dispute to mediation. If mediation does not resolve the dispute, you agree
   that the matter will be submitted to arbitration pursuant to the procedure
   established by the American Arbitration Association in the metropolitan area
   in which the center is located. The decision of the arbitrator will be
   binding on the parties. The non-prevailing party as determined by the
   arbitrator shall pay the prevailing parties attorney's fees and costs of the
   arbitration. Furthermore, if a court decision prevents or HQ elects not to
   submit this matter to arbitration, then the non-prevailing party as
   determined by the court shall pay the prevailing parties reasonable
   attorney's fees and costs. Nothing in this paragraph will prohibit HQ from
   seeking equitable relief including without limitation any action for removal
   of the client from the center after the license has been terminated or
   revoked.
D. This agreement is governed by the laws of the state in which the center is
   located.
E. Client may not assign this agreement without HQ's prior written consent,
   which will not be unreasonably withheld. F. This agreement is the entire
   agreement between you and HQ. It supercedes all prior agreements.
