         Section 9. Certain Company Protection Provisions. The following
provisions apply for the protection of the Company, and shall survive
indefinitely, beyond the duration of this Agreement:

                  a) Non-Solicitation. During the Restricted Period (as
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
by reason of his employment relationship with the Company. The Employee agrees
faithfully to keep in strict confidence, and not, either directly or indirectly,
to make known, divulge, reveal, furnish, make available or use (except for use
in the regular course of his employment duties) any such Confidential
Information; provided, however, that the Employee will not be deemed to have
violated this provision if he is compelled by valid legal process to disclose
any Confidential Information. The Employee acknowledges that all manuals,
instruction books, price lists, experiment logs or papers, information and
records and other information and aids relating to the Company's business, and
any and all other documents containing Confidential Information furnished to the
Employee by the Company or otherwise acquired or developed by the Employee,
shall at all times be the property of the Company. Upon the Employment
Termination Date, the Employee shall return to the Company any such property or
documents which are in his possession, custody or control, but his obligation of
confidentiality shall survive the Employment Termination Date until and unless
any such Confidential Information shall have become, through no fault of the
Employee, generally known to the public. The obligations of the Employee under
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.
                           83 Mercer Street, 3rd Floor

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.

understanding of the parties hereto with respect to the subject matter hereof.
This Agreement may not be modified, changed or amended except in a writing
signed by each of the parties hereto. This Agreement may be signed in
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.

         Section 15. Jurisdiction and Venue. The parties acknowledge that a
substantial portion of negotiations, anticipated performance and execution of
this Agreement occurred or shall occur in New York, New York and that,

proceeding; (c) waives any objection which it may have to the laying of venue of

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