13.  Independent Contract or Status. It is understood and agreed that in the
     performance of the Consulting Services by the Consultant hereunder, it is

     agent of Vianet. The Consultant will determine the hours of work of its
     employees and the Consultant's employees are not required to work any
     specified number of hours in any week. Any time off, including weekends and
     vacation, will be solely and entirely at the discretion of the Consultant.

     Vianet written or oral reports regarding its activities. Employees of the
     Consultant and others retained by the Consultant are not employees of
     Vianet for purposes of worker's compensation, unemployment insurance,
     medical, disability and group life insurance and they are not eligible to
     participate in any welfare, pension, profit sharing or fringe benefit plan
     or arrangement of Vianet.

     Services, Vianet shall pay to the Consultant a consulting fee as described
     in Appendix A to this document. In addition to the Base Fee, the Consultant

     Directors of Vianet as provided for in Appendix A. It is understood that
     Vianet will not withhold any income taxes, unemployment taxes or other
     taxes and that the Consultant is solely responsible for paying and
     reporting all taxes, including income taxes and estimates thereof for
     itself and all employees, agents or contractors. Vianet will report to the
     appropriate tax authorities the amounts paid to the Consultant and, even
     though the Consultant is an independent contractor, if Vianet is required
     by law, or is advised by its accountants or attorneys that it is required
     by law to deduct for withholding, or other taxes, it shall be free to do
     so, which taxes if not previously deducted shall be reclaimable from the
     consultant.

hereinafter defined), the Employee shall not directly or indirectly solicit any
customer or known prospective customer who has contracted with the Company to
purchase products or services during the then-preceding twelve month period. As
used herein, the term "Restricted Period" means the Employment Period.

                  b) Confidentiality. The Employee agrees and acknowledges that,
by reason of the nature of his duties as an officer and employee, he will have
or may have access to and become informed of confidential and secret information
which is a competitive asset of the Company ("Confidential Information"),
including without limitation any lists of customers or subscribers, financial
statistics, research data or any other statistics and plans contained in profit
plans, capital plans, critical issue plans strategic plans or marketing or
operation plans or other trade secrets of the Company and any of the foregoing
which belong to any person or company but to which the Employee has had access

this subsection are in addition to, and not in limitation or preemption of, all
other obligations of confidentiality which the Employee may have to the Company
under general legal or equitable principles.

                  c) Remedies. It is expressly agreed by the Employee and the
Company that these provisions are reasonable for purposes of preserving for the
Company its business, goodwill and proprietary information. It is also agreed
that if any provision is found by a court having jurisdiction to be unreasonable
because of scope, area or time, then that provision shall be amended to
correspond in scope, area and time to that considered reasonable by a court and
as amended shall be enforced and the remaining provisions shall remain
effective. In the event of any breach of these provisions by the Employee, the
parties recognize and acknowledge that a remedy at law will be inadequate and
the Company may suffer irreparable injury. The Employee acknowledges that the
services to be rendered by him are of a character giving them peculiar value,
the loss of which cannot be adequately compensated for in damages. Accordingly,
the Employee consents to injunctive and other appropriate equitable relief
without the posting of any type of bond or surety upon the institution of
proceedings therefor by the Company in order to protect the Company's rights.
Such relief shall be in addition to any other relief to which the Company may be
entitled at law or in equity.

         Section 10. Successors and Assigns. Except as hereinafter expressly
provided, the agreements, covenants, terms and provisions of this Agreement
shall bind the respective heirs, executors, administrators, successors and
assigns of the parties. This Agreement is personal in nature and neither of the
parties hereto shall, without the consent of the other, assign or transfer this
Agreement or any rights or obligations hereunder, except as provided in this
Section 10. Without limiting the foregoing, the Employee's right to receive
payments hereunder shall not be assignable or transferable, whether by pledge,
creation of a security interest or otherwise, and in the event of any attempted
assignment or transfer in contravention of this Section 10, the Company shall
have no liability to pay to the purported assignee or transferee any amount so
attempted to be assigned or transferred.

         Section 11. Notices. All notices and other communications that are
required or may be given under this Agreement shall be in writing and shall be
delivered personally or by certified mail addressed to the party concerned at
the following addresses:

If to the Company:         Vianet Technologies, Inc.

<PAGE>

All notices shall be effective upon receipt.

         Section 12. Waiver: Remedies Cumulative. No waiver of any right or
option hereunder by any party shall operate as a waiver of any other right or
option, or the same right or option as respects any subsequent occasion for its
exercise, or of any legal remedy. No waiver by any party of any breach of this
Agreement or of any agreement or covenant contained herein shall be held to
constitute a waiver of any other breach or a continuation of the same breach.
All remedies provided by this Agreement are in addition to all other remedies
provided under this Agreement or applicable law.

         Section 13. Governing Law: Severability. A substantial portion of
negotiations, anticipated performance and execution of this Agreement occurred
or shall occur in New York, New York and the various terms, provisions,
covenants and agreements, and the performance thereof, shall be construed,
interpreted and enforced under and with reference to the substantive laws of the
State of New York. It is the intention of the Company and the Employee to comply
fully with all laws and matters of public policy relating to employment
agreements and restrictive covenants, and this Agreement shall be construed
consistently with such laws and public policy to the extent possible. If and to
the extent any one or more covenants, agreements, terms and provisions of this
Agreement or any portion or portions thereof shall be held invalid or
unenforceable by a court of competent jurisdiction, then such covenants,
agreements, terms and provisions (or portions thereof) shall be deemed separable
from the remaining covenants, agreements, terms and provisions of this Agreement
and such holding shall in no way affect the validity or enforceability of any of
the other covenants, agreements, terms and provisions hereof.

This Agreement may not be modified, changed or amended except in a writing

counterparts, both of which shall be deemed an original hereof. The captions of
the several sections and subsections of this Agreement are not a part of the
context hereof, are inserted only for convenience in locating such subsections
and shall be ignored in construing this Agreement.

substantial portion of negotiations, anticipated performance and execution of

this Agreement, or in such other manner as may be provided under applicable laws
or court rules in the State of New York.

shall determine for any reason either not to register or to delay registration
of such securities, the Company may, at its election, give written notice of
such determination to the Optionee (the "Refusal Notice") and, thereupon, (i) in
the case of a determination not to register, shall be relieved of its obligation
to register the Option Shares in connection with such terminated registration
(but not from its obligation to pay the Registration Expenses (as defined
herein) in connection therewith), and (ii) in the case of a determination to
delay registering, shall be permitted to delay registering the Option Shares,
for the same period as the delay in registering such other securities.

of the Option Shares to this Section 4. For the purposes hereof, the phrase
"Registration Expenses" shall include all expenses incident to the Company's
performance of, or compliance with, this Section 4, including, without
limitation, (i) all registration, filing and NASD fees, (ii) all fees and
expenses of complying with securities or blue sky laws, (iii) all printing
expenses, (iv) the fees and disbursements of counsel for the Company and of its
independent public accountants, including the expenses of any special audits or
"cold comfort" letters required by or incident to such performance and
compliance, (v) the fees and disbursements of any one counsel and any one
accountant retained by the Optionee, (vi) premiums and other costs of policies
of insurance against liabilities arising out of the public offering of the
