ITEM 2.  Business Combination

         On December 30, 1999 the Company completed Merger Agreement (the
"Merger") under the terms of which the Company acquired all the outstanding
shares of PSI Communications, Inc. ("PSI"). PSI Communications, Inc., a designer
and manufacturer of fiber optic access equipment, specializes in the application
of advanced technologies that help Access and Exchange networks operate and
interact efficiently and reliably. Serving the emerging commercial multimedia
communications markets, PSI focuses on providing equipment to interface for
carrier access and enterprise fiber optic networks with their DLC Mux product.
PSI has built a product for the weakest chain in the Internet/Intranet link -
the last mile, also known as the local loop.
<PAGE>

The DLC system has the capability to transport Bellcore and ITU-T standard voice
and data interfaces over fiber optic T-1, E-1 and V.35 with plans to add
broadband Internet interfaces including ISDN, BRI/PRI, xDSL, IP video and Frame
Relay. This combination will result in the first true integrated V5.2 DLC fiber
optics multiplexer. This technology solves a long time telco concern: how to
reach the consumer market with high bandwidth capabilities, cost effectively.

     The Merger provided for PSI shareholders to receive 2,500,000 shares of
common stock of the Company in exchange for all the outstanding shares of PSI.
The Merger also provided that the Company's notes receivable from PSI
aggregating [$ ] be forgiven.

<PAGE>

Effective Time, all the properties, rights, privileges, powers and franchises of
PSI and Access shall vest in the Surviving Corporation, and all debts,
liabilities and duties of PSI and Access shall become the debts, liabilities and
duties of the Surviving Corporation.

                  (e)      Procedure for Payment.

                           (i) Immediately  after the  Effective  Time,
(A) Vianet will, on behalf of, and for the benefit of Access, furnish to
Continental Stock Transfer & Trust Company (the "Exchange Agent") a stock
certificate (issued in the name of the Exchange Agent or its nominee)
representing one half of that number of Vianet Shares equal to the product of
(I) the Conversion Ratio times (II) the number of outstanding PSI Shares (the
"Initial Shares") and (B) Vianet will cause the Exchange Agent to mail a letter
of transmittal (with instructions for its use) in the form attached hereto as
Exhibit B to each record holder of outstanding PSI Shares for the holder to use
in surrendering the certificates which represented his or its PSI Shares in
exchange for a certificate representing the number of Vianet Shares to which he
or it is entitled. Notwithstanding anything herein to the contrary, the balance
of the Merger Consideration (approximately1,250,000 Vianet Shares) to which the
Principal Stockholders would otherwise be entitled shall be deposited into
escrow (the "Escrowed Shares") with Gino Cischke, attorney at law, as escrow
agent (the "Escrow Agent") pursuant to the terms of an escrow agreement (the
"Escrow Agreement" to secure the indemnification obligations of the Principal
Stockholders pursuant to Section 9, post-closing adjustments pursuant to Section
2(i) or other obligations of PSI and/or the Principal Stockholders under this
Agreement. Any assertion by Vianet that it is entitled to receive any of the
Escrowed Shares on account of any of PSI's or the Principal Stockholders'
obligations hereunder shall be referred to herein as a "Claim".

                           (ii)     Release of Escrowed  Shares.  Subject to
Vianet's rights under the Escrow Agreement, the Escrowed Shares shall be
released as follows:

                                    a. On  the  nine  (9)  month  anniversary of
the Closing Date, Vianet and the Principal Stockholders will cause to be sent to
the Escrow Agent a Mutual Direction (as defined and in the form prescribed in
the Escrow Agreement), directing the Escrow Agent to release fifty percent (50%)
of the Escrowed Shares (approximately 625,000 shares, subject to reduction for
any Claims as provided in the Escrow Agreement) with appropriate instructions to
the Exchange Agent to have such released shares issued to the Principal
Stockholders.

                                    b. On the  eighteen  (18) month  anniversary
of the Closing Date, Vianet and the Principal Stockholders will cause to be sent
to the Escrow Agent a Mutual Direction directing the Escrow Agent to release
thirty percent (30%) of the Escrowed Shares (approximately 375,000 shares,

                                      -11-
<PAGE>

subject to reduction for any Claims as provided in the Escrow Agreement) with
appropriate instructions to the Exchange Agent to have such released shares
issued to the Principal Stockholders.

                                    c. On the two (2) year  anniversary of the
Closing Date, Vianet and the Principal Stockholders will cause to be sent to the
Escrow Agent a Mutual Direction directing the Escrow Agent to release the
balance, if any, of the Escrowed Shares with appropriate instructions to the
Exchange Agent to have any such released shares issued to the Principal
Stockholders.

Notwithstanding any other provision of this Agreement, if, on or before the two
(2) year anniversary of the Closing, PSI or any of the Principal Stockholders
provide documented evidence that is acceptable in the reasonable judgment of
Vianet, that Intelect Communications, Inc. (or its successors or assigns, if
applicable) has waived any potential claims against PSI as disclosed to Vianet
prior to the Closing, all but 500,000 of the Escrowed Shares promptly shall be
released to the Principal Stockholders.

                           (iii) Vianet will not pay any dividend or make any
distribution on Vianet Shares (with a record date at or after the Effective
Time) to any record holder of outstanding PSI Shares until the holder surrenders
for exchange his or its certificates which represented PSI Shares. Vianet
instead will pay the dividend or make the distribution to the Exchange Agent in
trust for the benefit of the holder pending surrender and exchange. Vianet may
cause the Exchange Agent to invest any cash the Exchange Agent receives from
Vianet as a dividend or distribution in one or more of the permitted investments
set forth on Exhibit C attached hereto; provided, however, that the terms and
conditions of the investments shall be such as to permit the Exchange Agent to
make prompt payments of cash to the holders of outstanding PSI Shares as
necessary. Vianet may cause the Exchange Agent to pay over to Vianet any net
earnings with respect to the investments. In no event, however, will any holder
of outstanding PSI Shares be entitled to any interest or earnings on the
dividend or distribution pending receipt.

                           (iv) Vianet may cause the Exchange  Agent to return
any Vianet Shares and dividends and distributions thereon remaining unclaimed
180 days after the Effective Time, and thereafter each remaining record holder
of outstanding PSI Shares shall be entitled to look to Vianet (subject to
abandoned property, escheat, and other similar laws) as a general creditor
thereof with respect to Vianet Shares and dividends and distributions thereon to
which he or it is entitled upon surrender of his or its certificates.

                           (v) Vianet  shall pay all  charges and  expenses of
the Exchange Agent and shall indemnify and hold harmless PSI and the Principal
Stockholders for such charges and expenses.

<PAGE>

                  (f) Closing of  Transfer  Records.  After the close of
business on the Closing Date, transfers of PSI Shares outstanding prior to the
Effective Time shall not be made on the stock transfer books of the Surviving
Corporation.

                  (g) Registration of, and Restrictions on, Vianet Shares. The
Vianet Shares issued and issuable in exchange for the PSI Shares shall be
subject to the following conditions and restrictions:

                           (i) Initial Shares.  Within one hundred and eighty
(180) days after the Closing Date, Vianet will make best efforts to file with
the SEC a registration statement covering the Initial Shares issued and issuable
in exchange for the PSI Shares; provided, however, that no Vianet Shares may be
traded prior to the nine (9) month anniversary of the Closing Date.

                           (ii) Escrowed  Shares.  Vianet will be obligated to
have filed with the SEC a registration statement with respect to all Escrowed
Shares issued to the Principal Shareholders as set forth in Section 2(e)(ii) so
that all such shares will be registered and freely trading on the two (2) year
anniversary of the Closing Date; provided, however, that no Escrowed Shares may
be traded prior to the two (2) year anniversary of the Closing Date.

                  (h) Legend. All certificates evidencing Vianet Shares
restricted by this Agreement shall bear a legend indicating the existence of the
restrictions imposed hereby and a stop transfer order may be placed with respect
to such securities. The legend referred to in the preceding sentence shall be
substantially in the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
         THE TRANSFER RESTRICTIONS AND OTHER TERMS OF THE AGREEMENT AND
         PLAN OF MERGER DATED AS OF DECEMBER 30, 1999 BY AND AMONG
         VIANET TECHNOLOGIES, INC., VIANET ACCESS, INC., PSI
         COMMUNICATIONS, INC. ("PSI ") AND CERTAIN SHAREHOLDERS OF PSI
         AND MAY NOT BE TRANSFERRED EXCEPT IN ACCORDANCE WITH SUCH
         AGREEMENT. A COPY OF SUCH AGREEMENT IS ON FILE AT THE
         PRINCIPAL OFFICE OF VIANET TECHNOLOGIES, INC. AND WILL BE
         FURNISHED UPON REQUEST TO THE HOLDER OF RECORD OF THE
         SECURITIES REPRESENTED BY THIS CERTIFICATE.

The holder of record of each certificate evidencing Vianet Shares shall have the
right to have such legend removed from all certificates evidencing Vianet Shares
on a pro rata basis as each Lock-Up period lapses and, in any event, upon
written request made at any time following the twenty-four (24) month
anniversary of the Closing Date.

                                      -13-

         (i) Post closing Adjustment. Vianet shall, within one hundred and
twenty (120) days after the Closing, deliver to the Principal Stockholders a
balance sheet of PSI as of the Closing Date audited by Edward Isaacs & Co., Inc.
(the "Audited Balance Sheet"). If the Net Worth of PSI as set forth on the
Audited Balance Sheet is less than the Net Worth of PSI as set forth on the Most
Recent Fiscal Month End Balance Sheet (the "Deficit") by an amount greater than
ten thousand dollars ($10,000) the Merger Consideration shall be reduced by the
amount of the Deficit. For purposes of this section 2(h), "Net Worth" shall mean
assets less liabilities. The Principal Stockholders shall have thirty (30) days
after receipt by the Principal Stockholders of the Audited Balance Sheet to
deliver to Vianet a written objection to the Audited Balance Sheet (the
"Objection"). The Objection must specify in reasonable detail the basis for
objecting to the Audited Balance Sheet. If the Objection is delivered in a
timely manner, Vianet and the Principal Stockholders shall then have thirty (30)
days to negotiate in good faith to resolve any dispute. If the dispute is not
resolved by Vianet and the Principal Stockholders within such thirty (30) day
period, Vianet and the Principal Stockholders shall jointly retain one of the
Big Five certified accounting public firms (the "Accountants") mutually agreed
upon by Vianet and the Principal Stockholders to resolve the dispute. The
determination of the Accountants shall be final and binding upon the parties.
The fees and expenses of the Accountants shall be shared equally by Vianet and
the Principal Stockholders. In order to effect the reduction in the Merger
Consideration, at closing, one half of the Vianet Shares to which each Principal
Stockholder would otherwise be entitled shall be deposited into escrow with the
Escrow Agent pursuant to the terms of the Escrow Agreement (the "Escrowed
Shares"). For the purposes of this section 2(h), the value of each Vianet Share
shall be calculated by reference to the then trailing five day average closing
price of Vianet common stock. If there is a Deficit based upon the Audited
Balance Sheet, agreement of the parties, or the determination of the
Accountants, within thirty (30) days after receipt by the Principal Stockholders
of the Audited Balance Sheet, agreement of the parties, or binding determination
of the Accountants, as the case may be, the Escrow Agent shall be instructed by
Vianet and the Principal Stockholders to deliver the number of Escrowed Shares
equal in value to the Deficit to the Exchange Agent with instructions to
register and deliver such shares to Vianet.

                  3. Representations and Warranties of Principal Stockholders.

                  Each of the Principal Stockholders represents and warrants to
Vianet that the statements contained in this Section 3 are correct and complete,
with respect to himself, as of the date of this Agreement and will be correct
and complete, with respect to himself, as of the Closing Date (as though made
then and as though the Closing Date were substituted for the date of this
Agreement throughout this Section 3).

result in the imposition of any Security Interest upon any of its assets). PSI
needs to give no notice to, make any filing with, or obtain any authorization,
consent, or approval of any government or governmental agency in order for the
Parties to consummate the transactions contemplated by this Agreement.

                           (vii) The unpaid Taxes of PSI (A) did not, as of the

each of the first six months beyond such ninety (90) day period registration of

month of the value of the shares not timely registered for each of the next six
months beyond such nine (9) month period registration of the Vianet Shares has

value of the shares not timely registered for each month beyond such fifteen
(15) month period registration of the Vianet Shares has not been accomplished by
Vianet, for a maximum Liquidated Damages amount equal to Two Million Five
Hundred Thousand Dollars ($2,500,000.00) In the event Vianet (x) fails for any
reason whatsoever to register the Vianet Shares for the benefit of the Principal
Stockholders and (y) fails to remit the Liquidated Damages within the date that
is the twenty-seven (27) month anniversary of the Closing Date, notwithstanding
any other provision in this Agreement, the Principal Stockholders shall have the
right, upon fifteen (15) days prior written notice to Vianet, to purchase all of
the then outstanding capital stock of Access from Vianet for the total purchase
price of Fifty Thousand Dollars ($50,000.00). Such amount shall be paid in cash

Stockholders' election to repurchase the stock of Access.

         9.       Survival and Indemnification.

                  (a) Survival and Indemnification. The representations and
warranties of PSI , the Principal Stockholders, Vianet and Access contained in
this Agreement shall survive the Closing hereunder and continue in full force
and effect thereafter (subject to any applicable statutes of limitations).

                  (b) Indemnification. The Principal Stockholders, jointly and
severally, agree to indemnify and hold harmless Vianet and its subsidiaries
(including, after the Effective Time, the Surviving Corporation and its
subsidiaries) (collectively, the "Vianet Group"), and the officers, directors
and employees of the Vianet Group (other than the Principal Stockholders) and
their successors and assigns (all of the foregoing entities and individuals to
be referred to hereafter as the "Indemnified Persons") from and against any and
all Adverse Consequences that any Indemnified Person may suffer resulting from,
arising out of, relating to, in the nature of, or caused by:

                           (i) any inaccuracy in, or any omission from, any of
the representations and warranties of the Principal Stockholders or PSI set
forth in this Agreement;

                           (ii) any failure of the Principal Stockholders or PSI
to comply with any of the obligations, covenants or agreements contained in this
Agreement;

                           (iii) any failure of a Principal Stockholder to
comply with any obligations, covenants or agreements contained in the Employment
Agreement dated the Closing Date between the Surviving Corporation and such
Principal Stockholder as the same may from time to time be amended, modified or
extended;

                           (iv) any action, suit, proceeding, claim or
investigation or regulatory proceeding to which the Surviving Corporation or its
Subsidiaries is or becomes a party or is or becomes subject (whether or not
known to Vianet) arising out of or based on any events or transactions which
have occurred or will occur prior to the Effective Time;

                           (v) any action, suit, proceeding, claim or
investigation to which the Surviving Corporation or any other Indemnified
Person, is or becomes a party or is or becomes subject arising out of the
Merger, this Agreement, or the transactions contemplated thereby; or

                           (vi) any Taxes of the Surviving Corporation or its
Subsidiaries with respect to any Tax year or portion thereof ending on or before
the Closing Date, or for any Tax year beginning before and ending after the

                                      -38-
<PAGE>

Closing Date to the extent allocable to the portion of such period beginning
before and ending on the Closing Date.

Notwithstanding any other provision of this Agreement, the indemnification
obligations of any or all of the Principal Stockholders shall be limited in any
circumstances to the Escrowed Shares.

                  (c)      Matters Involving Third Parties.

                           (i) If any third party shall notify any Indemnified
Party with respect to any matter (a "Third Party Claim") which may give rise to
a claim for indemnification against any other Party (the "Indemnifying Party")
under this Section 9, then the Indemnified Party shall promptly notify each
Indemnifying Party thereof in writing; provided, however, that no delay on the
part of the Indemnified Party in notifying any Indemnifying Party shall relieve
the Indemnifying Party from any obligation hereunder unless (and then solely to
the extent) the Indemnifying Party thereby is prejudiced.

                           (ii) Any Indemnifying Party will have the right to
defend the Indemnified Party against the Third Party Claim with counsel of its
choice reasonably satisfactory to the Indemnified Party so long as (A) the
Indemnifying Party notifies the Indemnified Party in writing within 10 days
after the Indemnified Party has given notice of the Third Party Claim that the
Indemnifying Party will indemnify the Indemnified Party from and against any
Adverse Consequences the Indemnified Party may suffer resulting from, arising
out of, relating to, in the nature of, or caused by the Third Party Claim, (B)
the Indemnifying Party provides the Indemnified Party with evidence reasonably
acceptable to the Indemnified Party that the Indemnifying Party will have the
financial resources to defend against the Third Party Claim and fulfill its
indemnification obligations hereunder, (C) the Third Party Claim involves only
money damages and does not seek an injunction or other equitable relief, (D)
settlement of, or an adverse judgment with respect to, the Third Party Claim is
not, in the good faith judgment of the Indemnified Party, likely to establish a
precedential custom or practice materially adverse to the continuing business
interests of the Indemnified Party, and (E) the Indemnifying Party conducts the
defense of the Third Party Claim actively and diligently.

                           (iii) So long as the Indemnifying Party is conducting
the defense of the Third Party Claim in accordance with Section 9(c)(ii) above,
(A) the Indemnified Party may retain separate co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim, (B) the
Indemnified Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnifying Party (not to be withheld unreasonably), and (C) the

                                      -39-
<PAGE>

Indemnifying Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnified Party (not to be withheld unreasonably).

                           (iv) In the event any of the conditions in Section
9(c)(ii) above is or becomes unsatisfied, however, (A) the Indemnified Party may
defend against, and consent to the entry of any judgment or enter into any
settlement with respect to, the Third Party Claim in any manner it reasonably
may deem appropriate (and the Indemnified Party need not consult with, or obtain
any consent from, any Indemnifying Party in connection therewith), (B) the
Indemnifying Parties will reimburse the Indemnified Party promptly and
periodically for the costs of defending against the Third Party Claim (including
reasonable attorneys' fees and expenses), and (C) the Indemnifying Parties will
remain responsible for any Adverse Consequences the Indemnified Party may suffer
resulting from, arising out of, relating to, in the nature of, or caused by the
Third Party Claim to the fullest extent provided in this Section 9.

                  (d) Indemnification  Payments. All indemnification payments
under this Section 9 may, at Vianet's option and in its sole discretion, be
deemed adjustments to the Purchase Price.

                  (e) Recovery from Escrowed Shares. Without in any way limiting
Vianet's rights and the obligations of the Principal Stockholders under this
Section 9, Vianet shall have the right to seek payment of the indemnification
obligations of the Principal Stockholders from the Escrowed Shares pursuant to
the Terms of the Escrow Agreement; provided, however, that such indemnification
obligations shall be limited to the Escrowed Shares in any event.

                  (f) Other Indemnification Provisions. The foregoing
indemnification provisions are in addition to, and not in derogation of, any
statutory, equitable, or common law remedy (including without limitation any
such remedy arising under Environmental, Health, and Safety Requirements) any
Party may have with respect to PSI or the transactions contemplated by this
Agreement.

         10. Termination.

                  (a) Termination of Agreement. Either of the Parties may
terminate this Agreement with the prior authorization of its board of directors
(whether before or after stockholder approval) as provided below:

                           (i) the Parties may terminate this Agreement by
mutual written consent at any time prior to the Effective Time;

                           (ii) Vianet and Access may terminate this Agreement
by giving written notice to PSI at any time prior to the Effective Time (A) in
the event PSI has breached any material representation, warranty, or covenant

                                      -40-
<PAGE>

contained in this Agreement, Vianet or Access has notified PSI of the breach,
and the breach has continued without cure for a period of 5 days after the
notice of breach or (B) if the Closing shall not have occurred on or before
January 31, 2000, by reason of the failure of any condition precedent under
Section 8(a) hereof (unless the failure results primarily from Vianet or Access
breaching any representation, warranty, or covenant contained in this
Agreement);

                           (iii) PSI may terminate this Agreement by giving
written notice to Vianet and Access at any time prior to the Effective Time (A)
in the event Vianet or Access has breached any material representation,
warranty, or covenant contained in this Agreement, PSI has notified Vianet and
Access of the breach, and the breach has continued without cure for a period of
5 days after the notice of breach or (B) if the Closing shall not have occurred
on or before January 31, 2000, by reason of the failure of any condition
precedent under Section 8(b) hereof (unless the failure results primarily from
PSI breaching any representation, warranty, or covenant contained in this
Agreement); or

                           (iv) any Party may terminate this Agreement by giving
written notice to the other Party at any time after the Special PSI Meeting in
the event this Agreement and the Merger fail to receive the Requisite PSI
Stockholder Approval.

                  (b) Effect of Termination. If any Party terminates this
Agreement pursuant to Section 10(a) above, all rights and obligations of the
Parties hereunder shall terminate without any liability of any Party to any
other Party (except for any liability of any Party then in breach); provided,
however, that the confidentiality provisions contained in Section 7(g) above and
expense provisions contained in Section 11(l) shall survive any such
termination. In the event of any such termination pursuant to Section 10(a)
above, the technology license that is contained in Section 4 of that certain
Letter of Intent between Vianet, PSI and the Principal Stockholders dated July
13, 1999 shall remain in force according to its terms.

good faith is required by applicable law or any listing or trading agreement

                  WHEREAS, the substantial benefits to be received by the
Executive as a Principal Stockholder of PSI and, following the Merger, a
stockholder of Vianet, are good and sufficient consideration to bind Executive
to those certain Company-protection provisions set forth in Sections 5 through 8
hereof;

                  WHEREAS, as a condition to consummation of the Merger, Vianet
has required Executive to enter into this Employment Agreement, and Vianet would
not have entered into the Agreement of Merger or consummate the Merger if it did
not have the benefit of the Company-protection provisions set forth in Sections
5 through 8 hereof; and

                  WHEREAS, based on the foregoing, Executive and the Company
desire to enter into this Employment Agreement setting forth the terms and
conditions of Executive's employment by the Company.

                  NOW, THEREFORE, in consideration of the respective covenants
and agreements of the parties contained herein, the parties hereto agree as
follows:

                  1. Employment Term. The Company hereby agrees to employ
Executive, and Executive hereby agrees to accept such employment, on the terms
and conditions set forth herein. The parties agree that the term of employment
shall commence as of the date hereof and will end one day immediately prior to

                                      -47-
<PAGE>

the second anniversary of the date hereof (the "Original Term"), unless
terminated earlier as provided for herein, provided, however, that the Original
Term and each subsequent renewal thereof shall be automatically extended on a
month-to-month basis ("Renewal Term") unless at least sixty (60) days but not
more than ninety (90) days prior to the end of the Original Term or the current
Renewal Term either party gives written notice to the other of its intent to
terminate the Agreement as of the end of the Original Term or Renewal Term, as
the case may be (the Original Term and any subsequent Renewal Term to be
referred herein, collectively, as the "Term").

                  2. Position and Duties.

                  (a) Upon the commencement of the Term, the Company shall
employ Executive as its Executive Vice President of Operations during the term.
Executive shall fulfill such duties and responsibilities as are consistent with
such position and as are assigned to him from time to time by the Board of
Directors of the Company or its delegate.

                  (b) Executive shall devote his best efforts and full business
time and attention to the diligent, faithful, efficient and competent
performance of his duties and responsibilities hereunder and will not engage in
any other ventures or enterprises. Executive shall at all times comport himself
in such manner that his conduct will not reasonably be expected to prejudice or
injure the reputation of the Company or any corporation, limited liability
company, partnership, association or other entity directly or indirectly
controlling, controlled by or under common control with the Company (an
"Affiliate") in any way. Executive shall devote his best efforts and business
time exclusively to the advancement of the interests of the Company and its
Affiliates. Notwithstanding the above, Executive may serve as a director,
trustee, or advisor of other organizations, or engage in charitable, civic,
and/or governmental activities provided that such service and activities do not
interfere with Executive performing his duties under this Agreement. Executive
may also engage in personal activities, including, without limitation, personal
investments, provided that such activities do not interfere or conflict with his
performance of duties hereunder.

                  3. Termination.

                  (a) Death. This Agreement and Executive's employment hereunder
shall terminate upon the death of Executive.

                  (b) Cause. The Company may terminate this Agreement and
Executive's employment hereunder for Cause, as defined below, effective at the
times indicated below. For purposes of this Section 3(b) the term "Cause" shall
mean:

                      (i) A breach by Executive of any of the material terms of
this Agreement and failure to cure such breach within fifteen (15) days after
receipt of written notice thereof;

                      (ii) Failure by Executive to devote all business time
exclusively to the performance of his duties hereunder and failure to cure such
breach within fifteen (15) days after written receipt of notice thereof;


                                      -48-
<PAGE>

                      (iii) Willful misconduct, dishonesty, alcoholism,
addiction to illegal drugs, conviction of a felony or its equivalent under local
law or engaging in any discrimination or sexual harassment of employees of the
Company or of customers or vendors of the Company;

                      (iv) Persistent incompetence or inefficiency, habitual or
gross negligence in the performance of Executive's duties, or failure to abide
by instructions received from the Board of Directors of the Company or its
delegate or the violation of policies and practices adopted by the Company or
Vianet, and failure to cure the same within fifteen (15) days after receipt of
written notice thereof.

                      Termination under clauses (i), (ii) and (iv) above shall
be effective at the conclusion of the fifteen (15) day cure period without
further notice and termination under clause (iii) above shall be effective
immediately upon the occurrence of the conduct specified therein and without
prior notice.

                      (c) Incapacity. The Company may terminate this Agreement
and Executive's employment hereunder, immediately, and without prior notice, if,
as a result of Executive's incapacity due to physical or mental illness or
injury, Executive shall have been unable to perform adequately his duties as
herein provided for ninety (90) consecutive days or an aggregate of ninety (90)
days during any twelve (12) month period during the Term.

                      (d) Termination by Executive Without Cause. Executive may
terminate this Agreement, without cause, upon six (6) months prior written
notice to the Company; provided however, that during such six (6) month period,
Executive shall use his reasonable best efforts to assist the Company in finding
a qualified replacement. Such termination shall be effective upon expiration of
the six (6) month notice period.

                      (e) Termination by Executive for Cause. Executive may
terminate this Agreement and Executive's employment hereunder for Executive's
Cause, as defined below. "Executive's Cause" shall mean:

                      (i) a breach by the Company of any of the terms of this
Agreement and failure to cure such breach within fifteen (15) days after notice
thereof or

                      (ii) the working conditions afforded to the Executive are
habitually and grossly intolerable and such conditions are not cured within (15)
days after notice thereof;

                      (f) No Further Payments Upon Termination. Except as
otherwise provided below, upon any termination enumerated in this Paragraph 3,
Executive's right to further compensation and benefits under this Agreement
shall cease, provided, however, that Executive shall remain entitled to any
unpaid compensation and benefits accrued prior to such termination and to any
expense or reimbursement to which he was entitled at the date of such
termination. In addition to the foregoing, upon: (i) termination of this
Agreement by Executive pursuant to Section 3(e) above, or (ii) termination of
this Agreement by the Company for for any reason other than Cause, Executive
shall be entitled to, and the Company shall pay to Executive within five (5)

                                      -49-
<PAGE>

days after such termination, a lump sum payment equal to the lesser of six (6)
months base salary or the base salary payable to Executive during the remainder
of the Original Term or then current Renewal Term, as the case may be, plus any
other amount(s) to which Executive is entitled under this agreement under the
Company's benefit plans and arrangements or otherwise.

                      4. Compensation and Benefits.

                      (a) Base Salary. During the Term, the Company shall pay to
Executive as compensation for his services hereunder, salary at the rate of $
175,000.00 per annum, less appropriate deductions (including legally required
withholdings and elective deductions for participation in benefit programs) and
payable in accordance with the Company's general payroll practice. The Board of
Directors of the Company shall evaluate the Executive for merit increases in his
base salary hereunder at least annually, but shall not, in any event, reduce
Executive's base salary during the Term.

                      (b) Benefits and Perquisites. Executive shall be entitled
to participate in or receive benefits under any pension, savings, life
insurance, health and accident plan or other arrangement which is from time to
time made available to similarly situated Executives of the Company, subject to
and on a basis consistent with the terms, conditions and overall administration
of such plans or arrangements.

                      (c) Expenses. During the Term, Executive shall be entitled
to receive reimbursement for reasonable expenses actually incurred by him in the
performance of his duties hereunder (in accordance with the policies and
procedures established by the Board of Directors of the Company), provided that
any such expenses shall be reimbursable only to the extent that Executive
properly accounts therefor in accordance with Company policy and applicable law.

                      (d) Vacations. Executive shall be entitled to paid
vacations and holidays in accordance with Company policy in effect from time to
time; provided, however, that Executive shall be entitled to at least four (4)
weeks of paid vacation each year.

                      5. Agreement Not to Compete.

                      Executive agrees during the Term and that in the event of
separation as outlined in Section 3, Executive shall not for a period of two (2)
years after termination, directly or indirectly, engage in or conduct, be
employed directly or indirectly by, serve as an officer or director of, hold an
equity interest in, or provide advice or act as a consultant to, any person or
entity which is, or is about to be engaged, in any business which is directly
competitive with the business of the Company or its Affiliates (a "Competitive
Business"); provided that, nothing herein shall prohibit Executive from owning
not more than five percent (5%) of the outstanding capital stock of any Company
listed on a national securities exchange so long as Executive is otherwise not
in breach of the covenants set forth above; and provided further, that this
section 5 shall not apply if the Executive terminates this agreement pursuant to
Section 3 (e). Executive acknowledges and agrees that because the Company is in
the communications technology business, its market is geographically broad. As
such, the Executive acknowledges and agrees that his agreement not to compete
prohibits the Executive from engaging in a Competitive Business anywhere in the
world. In the event a court of competent jurisdiction determines that this
provision is not enforceable by its terms for lack of a geographical area, the
parties agree to request such court to modify this provision to include a
reasonable geographical area. The parties do not intend that this provision be
deemed unenforceable for lack of a specified geographical area.

                      6. Non-Solicitation. Executive agrees that during the
Term, and for a period of two (2) years after the expiration or termination of
this Agreement and Executive's employment hereunder, regardless of the reason
for termination of employment, Executive shall not:

                      (i) directly or indirectly, solicit any person,
corporation, limited liability company, partnership or other business entity
which is, at the time of such solicitation, or was, within the prior year, a
customer, client or licensee of the Company or of any Affiliate, (x) for the
purpose of engaging with any such customer in any business transactions of the
nature presently performed by, or the business (or any part thereof) presently
conducted by, the Company or any Affiliate, or (y) for the purpose of engaging
with any such customer in any business transactions of the nature performed by,
or the business (or any part thereof) conducted by the Company, or any
Affiliate, at any time during the Term;

                      (ii) directly or indirectly solicit, induce, influence,
request or advise any customer, client or licensee of the Company or any
Affiliate to withdraw, curtail, cancel, discontinue, reduce or modify such
customer's, client's or licensee's business or business relationship with the
Company or any Affiliate; or

                      (iii) directly or indirectly employ, solicit for
employment or advise, or recommend to any other person that he employ or solicit
for employment, any person employed at that time, or at any time during the
prior year, by the Company or an Affiliate.

                      7. Non-disclosure.

                      (a) During the Term and thereafter, Executive shall not,
without the written consent of the Board of Directors of the Company, disclose
or use (except in the course of his employment hereunder and in furtherance of
the business of the Company or an Affiliate) any Confidential Information of the
Company, or any Affiliate. "Confidential Information" shall mean all
confidential information, proprietary data and trade secrets of the Company and
its Affiliates including, without limitation, the following: the identity,
written lists, or descriptions of any customers or referral sources, financial
statements, cost reports, or other financial information; contract proposals or
bidding information; business plans; marketing plans; budgets; projections;
training and operations methods and manuals; personnel records; fee structures;
sales data; management systems, policies or procedures, including related forms
and manuals; concepts; ideas; drawings; discoveries; inventions; processes;
designs; formulas; programs; computer programs; object code; source code;
engineering tolerances; know-how; and product developments. Notwithstanding the
foregoing, Confidential Information shall not include information concerning the
Company, or its Affiliates, known to Executive which (i) becomes public
knowledge (other than by acts by Executive or his representatives in violation
of this Agreement), (ii) becomes known to Executive on a non-confidential basis
from a source other than the Company, provided that such source is not known or
should not reasonably have been known by Executive to be bound by a
confidentiality agreement with or other obligation of secrecy to the Company, or
(iii) Executive is required to disclose in a judicial, administrative or
governmental proceeding (a "Legal Proceeding"). In the event Executive is
requested to disclose Confidential Information in a Legal Proceeding as
contemplated by clause (iii) of the previous sentence, Executive shall provide
the Company with prompt notice of such request so that the Company may timely
seek an appropriate protective order or waive compliance with this Section 7.
If, after giving such notice, and in the absence of a protective order or the
receipt of a waiver hereunder, Executive is, in the opinion of his legal counsel
compelled to disclose such information to any tribunal or else stand liable for
contempt or other censure or penalty, then Executive may disclose such
information to such tribunal, to the extent so required without liability
hereunder.

                      (b) Executive agrees that upon expiration or termination
of this Agreement and Executive's employment hereunder, regardless of the reason
for termination, he will immediately return to the Company any and all physical
manifestations of Confidential Information and all copies of the same, and
Confidential Information of any customers of the Company and its Affiliates,
within his possession, and will not at any time thereafter copy or reproduce the
same.

                      8. Inventions and Pending Patent Applications. (a)
Executive agrees that all inventions, designs, improvements, writings, and
discoveries (collectively, "Inventions") made during the Term and pertaining to
the business conducted by the Company shall be the exclusive property of the
Company. Executive hereby transfers and assigns to the Company all right, title
and interest in and to the Inventions, including any and all domestic and
foreign patent rights therein and any renewals thereof. Executive shall assist
the Company in obtaining patents and copyrights on all Inventions deemed
suitable for patent or copyright by the Company and shall execute all documents
and do all things necessary to obtain letters patent or copyrights, as the case
may be, to vest the Company with full and exclusive title thereto, and to
protect the same against infringements by others.

                                      -52-
<PAGE>

                      (b) Executive agrees to execute and deliver all
applications for patent, including all divisional, continuation, reissue and
other applications for patent on the invention(s) set forth in the pending
applications listed in Section 4(l)(iii) of the Disclosure Schedule to the
Agreement of Merger and all assignments thereof to the Company, Vianet or their
assigns, to communicate to the Company, Vianet or their representatives all
facts known to Executive respecting said invention(s), whenever requested, to
testify in any interference's or other legal proceedings in which any of said
applications or patents resulting therefrom may become involved, to sign all
lawful papers, make all rightful oaths, and to do generally everything
reasonably necessary to assist the Company, Vianet, their successors, assigns
and nominees to obtain patent protection for said invention(s) in the United
States and all other countries, all at the cost and expense of the Company and
Vianet.

                      9. Successors and Assigns. This Agreement is personal in
nature and Executive may not assign or transfer this Agreement or any right or
obligation hereunder to any other person. The Company, however, may assign or
transfer this Agreement and any of its rights or obligations hereunder to any
Affiliate or Successor Corporation or entity without the consent of Executive.
Any purported assignment in violation of the terms hereof shall be void and of
no effect. This Agreement and all rights hereunder shall inure to the benefit of
and be enforceable by Executive, the Company and the Company's successors and
assigns.

                      10. Notice. Notices and all other communications required

                      15. Waiver. The observation or performance of any
condition or obligation imposed upon Executive hereunder may be waived only upon

thereof and shall not constitute a waiver of any other condition or obligation
of Executive under this Agreement.

                      16. Equitable Relief. Executive acknowledges and agrees

                              W I T N E S S E T H :

                  WHEREAS, Executive was previously a shareholder, officer and
director of PSI Communications, Inc. ("PSI");

                  WHEREAS, effective upon the filing of a Certificate of Merger
with the Secretary of State of Delaware, Vianet Access, Inc., a wholly owned
subsidiary of Vianet Technologies, Inc. ("Vianet"), merged into PSI (the
"Merger"), and PSI changeD its name to Vianet Access, Inc. ("Access"), pursuant
to the terms and provisions of an Agreement and Plan of Merger dated December
30, 1999 herewith (the "Agreement of Merger"), by and among Vianet , Access,
PSI, GNS, Ltd., a Texas limited partnership and certain stockholders of PSI,
including Executive, whereupon the Company became a wholly owned subsidiary of
Vianet;

                  WHEREAS, Executive is a Principal Stockholder (as defined in
the Agreement of Merger) of PSI, and pursuant to the Agreement of Merger, will
sell all of his shares of PSI in exchange for shares of Vianet and other good
and sufficient consideration;

                  WHEREAS, the substantial benefits to be received by the
Executive as a Principal Stockholder of PSI and, following the Merger, a
stockholder of Vianet, are good and sufficient consideration to bind Executive
to those certain Company-protection provisions set forth in Sections 5 through 8
hereof;

                  WHEREAS, as a condition to consummation of the Merger, Vianet
has required Executive to enter into this Employment Agreement, and Vianet would

                                      -58-
<PAGE>

shall commence as of the date hereof and will end one day immediately prior to
the second anniversary of the date hereof (the "Original Term"), unless
terminated earlier as provided for herein, provided, however, that the Original
Term and each subsequent renewal thereof shall be automatically extended on a
month-to-month basis ("Renewal Term") unless at least sixty (60) days but not
more than ninety (90) days prior to the end of the Original Term or the current
Renewal Term either party gives written notice to the other of its intent to
terminate the Agreement as of the end of the Original Term or Renewal Term, as
the case may be (the Original Term and any subsequent Renewal Term to be
referred herein, collectively, as the "Term").

                  2. Position and Duties.

                  (a) Upon the commencement of the Term, the Company shall
employ Executive as its Executive Vice President and General Manager during the

with such position and as are assigned to him from time to time by the Board of
Directors of the Company or its delegate. Executive shall also be entitled to a
seat on the Board of Directors of the Company during the Term.

                  (b) Executive shall devote his best efforts and full business
time and attention to the diligent, faithful, efficient and competent
performance of his duties and responsibilities hereunder and will not engage in
any other ventures or enterprises. Executive shall at all times comport himself
in such manner that his conduct will not reasonably be expected to prejudice or
injure the reputation of the Company or any corporation, limited liability
company, partnership, association or other entity directly or indirectly
controlling, controlled by or under common control with the Company (an
"Affiliate") in any way. Executive shall devote his best efforts and business
time exclusively to the advancement of the interests of the Company and its
Affiliates. Notwithstanding the above, Executive may serve as a director,
trustee, or advisor of other organizations, or engage in charitable, civic,
and/or governmental activities provided that such service and activities do not
interfere with Executive performing his duties under this Agreement. Executive
may also engage in personal activities, including, without limitation, personal
investments, provided that such activities do not interfere or conflict with his
performance of duties hereunder.

                  3. Termination.

                  (a) Death. This Agreement and Executive's employment hereunder
shall terminate upon the death of Executive.

                  (b) Cause. The Company may terminate this Agreement and
Executive's employment hereunder for Cause, as defined below, effective at the
times indicated below. For purposes of this Section 3(b) the term "Cause" shall
mean:

Agreement and failure to cure such breach within fifteen (15) days after receipt
of written notice thereof;

                                      -59-
<PAGE>

                  (ii) Failure by Executive to devote all business time
exclusively to the performance of his duties hereunder and failure to cure such
breach within fifteen (15) days after written receipt of notice thereof;

                  (iii) Willful misconduct, dishonesty, alcoholism, addiction to
illegal drugs, conviction of a felony or its equivalent under local law or
engaging in any discrimination or sexual harassment of employees of the Company
or of customers or vendors of the Company;

                  (iv) Persistent incompetence or inefficiency, habitual or
gross negligence in the performance of Executive's duties, or failure to abide
by instructions received from the Board of Directors of the Company or its
delegate or the violation of policies and practices adopted by the Company or
Vianet, and failure to cure the same within fifteen (15) days after receipt of
written notice thereof.

                  Termination under clauses (i), (ii) and (iv) above shall be
effective at the conclusion of the fifteen (15) day cure period without further
notice and termination under clause (iii) above shall be effective immediately
upon the occurrence of the conduct specified therein and without prior notice.

                  (c) Incapacity. The Company may terminate this Agreement and
Executive's employment hereunder, immediately, and without prior notice, if, as
a result of Executive's incapacity due to physical or mental illness or injury,
Executive shall have been unable to perform adequately his duties as herein
provided for ninety (90) consecutive days or an aggregate of ninety (90) days
during any twelve (12) month period during the Term.

                  (d) Termination by Executive Without Cause. Executive may
terminate this Agreement, without cause, upon six (6) months prior written
notice to the Company; provided however, that during such six (6) month period,
Executive shall use his reasonable best efforts to assist the Company in finding
a qualified replacement. Such termination shall be effective upon expiration of
the six (6) month notice period.

                  (e) Termination by Executive for Cause. Executive may
terminate this Agreement and Executive's employment hereunder for Executive's
Cause, as defined below. "Executive's Cause" shall mean:

                  (i) a breach by the Company of any of the terms of this
Agreement and failure to cure such breach within fifteen (15) days after notice
thereof or

                  (ii) the working conditions afforded to the Executive are
habitually and grossly intolerable and such conditions are not cured within (15)
days after notice thereof;

                  (f) No Further Payments Upon Termination. Except as otherwise
provided below, upon any termination enumerated in this Paragraph 3, Executive's
right to further compensation and benefits under this Agreement shall cease,
provided, however, that Executive shall remain entitled to any unpaid
compensation and benefits accrued prior to such termination and to any expense
or reimbursement to which he was entitled at the date of such termination. In

                                      -60-
<PAGE>

addition to the foregoing, upon: (i) termination of this Agreement by Executive
pursuant to Section 3(e) above, or (ii) termination of this Agreement by the
Company for for any reason other than Cause, Executive shall be entitled to, and
the Company shall pay to Executive within five (5) days after such termination,
a lump sum payment equal to the lesser of six (6) months base salary or the base
salary payable to Executive during the remainder of the Original Term or then
current Renewal Term, as the case may be, plus any other amount(s) to which
Executive is entitled under this agreement under the Company's benefit plans and
arrangements or otherwise.

                  4. Compensation and Benefits.

                  (a) Base Salary. During the Term, the Company shall pay to
Executive as compensation for his services hereunder, salary at the rate of $
200,000.00 per annum, less appropriate deductions (including legally required
withholdings and elective deductions for participation in benefit programs) and
payable in accordance with the Company's general payroll practice. The Board of
Directors of the Company shall evaluate the Executive for merit increases in his
base salary hereunder at least annually, but shall not, in any event, reduce
Executive's base salary during the Term.

                  (b) Benefits and Perquisites. Executive shall be entitled to
participate in or receive benefits under any pension, savings, life insurance,
health and accident plan or other arrangement which is from time to time made
available to similarly situated Executives of the Company, subject to and on a
basis consistent with the terms, conditions and overall administration of such
plans or arrangements.

                  (c) Expenses. During the Term, Executive shall be entitled to
receive reimbursement for reasonable expenses actually incurred by him in the
performance of his duties hereunder (in accordance with the policies and
procedures established by the Board of Directors of the Company), provided that
any such expenses shall be reimbursable only to the extent that Executive
properly accounts therefor in accordance with Company policy and applicable law.

                  (d) Vacations. Executive shall be entitled to paid vacations
and holidays in accordance with Company policy in effect from time to time;
provided, however, that Executive shall be entitled to at least four (4) weeks

                  5. Agreement Not to Compete.

                  Executive agrees during the Term and that in the event of
separation as outlined in Section 3, Executive shall not for a period of two (2)
years after termination, directly or indirectly, engage in or conduct, be
employed directly or indirectly by, serve as an officer or director of, hold an
equity interest in, or provide advice or act as a consultant to, any person or
entity which is, or is about to be engaged, in any business which is directly
competitive with the business of the Company or its Affiliates (a "Competitive
Business"); provided that, nothing herein shall prohibit Executive from owning
not more than five percent (5%) of the outstanding capital stock of any Company
listed on a national securities exchange so long as Executive is otherwise not
in breach of the covenants set forth above; and provided further, that this
section 5 shall not apply if the Executive terminates this agreement pursuant to
Section 3 (e). Executive acknowledges and agrees that because the Company is in
the communications technology business, its market is geographically broad. As
such, the Executive acknowledges and agrees that his agreement not to compete
prohibits the Executive from engaging in a Competitive Business anywhere in the
world. In the event a court of competent jurisdiction determines that this
provision is not enforceable by its terms for lack of a geographical area, the
parties agree to request such court to modify this provision to include a
reasonable geographical area. The parties do not intend that this provision be
deemed unenforceable for lack of a specified geographical area.

                  6. Non-Solicitation. Executive agrees that during the Term,
and for a period of two (2) years after the expiration or termination of this
Agreement and Executive's employment hereunder, regardless of the reason for
termination of employment, Executive shall not:

                  (i) directly or indirectly, solicit any person, corporation,
limited liability company, partnership or other business entity which is, at the
time of such solicitation, or was, within the prior year, a customer, client or
licensee of the Company or of any Affiliate, (x) for the purpose of engaging
with any such customer in any business transactions of the nature presently
performed by, or the business (or any part thereof) presently conducted by, the
Company or any Affiliate, or (y) for the purpose of engaging with any such
customer in any business transactions of the nature performed by, or the
business (or any part thereof) conducted by the Company, or any Affiliate, at
any time during the Term;

                  (ii) directly or indirectly solicit, induce, influence,
request or advise any customer, client or licensee of the Company or any
Affiliate to withdraw, curtail, cancel, discontinue, reduce or modify such
customer's, client's or licensee's business or business relationship with the
Company or any Affiliate; or

                  (iii) directly or indirectly employ, solicit for employment or
advise, or recommend to any other person that he employ or solicit for
employment, any person employed at that time, or at any time during the prior
year, by the Company or an Affiliate.

                  (a) During the Term and thereafter, Executive shall not,
without the written consent of the Board of Directors of the Company, disclose

the business of the Company or an Affiliate) any Confidential Information of the
Company, or any Affiliate. "Confidential Information" shall mean all
confidential information, proprietary data and trade secrets of the Company and
its Affiliates including, without limitation, the following: the identity,
written lists, or descriptions of any customers or referral sources, financial
statements, cost reports, or other financial information; contract proposals or
bidding information; business plans; marketing plans; budgets; projections;

designs; formulas; programs; computer programs; object code; source code;
engineering tolerances; know-how; and product developments. Notwithstanding the
foregoing, Confidential Information shall not include information concerning the
Company, or its Affiliates, known to Executive which (i) becomes public
knowledge (other than by acts by Executive or his representatives in violation
of this Agreement), (ii) becomes known to Executive on a non-confidential basis
from a source other than the Company, provided that such source is not known or
should not reasonably have been known by Executive to be bound by a
confidentiality agreement with or other obligation of secrecy to the Company, or
(iii) Executive is required to disclose in a judicial, administrative or
governmental proceeding (a "Legal Proceeding"). In the event Executive is
requested to disclose Confidential Information in a Legal Proceeding as
contemplated by clause (iii) of the previous sentence, Executive shall provide
the Company with prompt notice of such request so that the Company may timely
seek an appropriate protective order or waive compliance with this Section 7.
If, after giving such notice, and in the absence of a protective order or the
receipt of a waiver hereunder, Executive is, in the opinion of his legal counsel
compelled to disclose such information to any tribunal or else stand liable for
contempt or other censure or penalty, then Executive may disclose such
information to such tribunal, to the extent so required without liability
hereunder.

                  (b) Executive agrees that upon expiration or termination of
this Agreement and Executive's employment hereunder, regardless of the reason
for termination, he will immediately return to the Company any and all physical
manifestations of Confidential Information and all copies of the same, and
Confidential Information of any customers of the Company and its Affiliates,
within his possession, and will not at any time thereafter copy or reproduce the
same.

                  8. Inventions and Pending Patent Applications. (a) Executive
agrees that all inventions, designs, improvements, writings, and discoveries
(collectively, "Inventions") made during the Term and pertaining to the business
conducted by the Company shall be the exclusive property of the Company.
Executive hereby transfers and assigns to the Company all right, title and
interest in and to the Inventions, including any and all domestic and foreign
patent rights therein and any renewals thereof. Executive shall assist the
Company in obtaining patents and copyrights on all Inventions deemed suitable
for patent or copyright by the Company and shall execute all documents and do
all things necessary to obtain letters patent or copyrights, as the case may be,
to vest the Company with full and exclusive title thereto, and to protect the
same against infringements by others.

                  (b) Executive agrees to execute and deliver all applications
for patent, including all divisional, continuation, reissue and other
applications for patent on the invention(s) set forth in the pending
applications listed in Section 4(l)(iii) of the Disclosure Schedule to the
Agreement of Merger and all assignments thereof to the Company, Vianet or their

testify in any interference's or other legal proceedings in which any of said
applications or patents resulting therefrom may become involved, to sign all
lawful papers, make all rightful oaths, and to do generally everything

States and all other countries, all at the cost and expense of the Company and
Vianet.

                  9. Successors and Assigns. This Agreement is personal in
nature and Executive may not assign or transfer this Agreement or any right or
obligation hereunder to any other person. The Company, however, may assign or
transfer this Agreement and any of its rights or obligations hereunder to any
Affiliate or Successor Corporation or entity without the consent of Executive.
Any purported assignment in violation of the terms hereof shall be void and of
no effect. This Agreement and all rights hereunder shall inure to the benefit of
and be enforceable by Executive, the Company and the Company's successors and
assigns.

                  10. Notice. Notices and all other communications required or

obligation imposed upon Executive hereunder may be waived only upon the written

it is impossible to measure any money damages that will accrue to the Company or

                  EXECUTIVE EMPLOYMENT AGREEMENT dated as of January 1, 2000 by
and between VIANET ACCESS, INC, a Delaware corporation (formerly known as PSI

Custer Road (Suite 101), Plano, Texas 75023 (the "Company"), and Todd Grassi,
1418 Tascosa Court, Allen, Texas 75013 ("Executive").

                              W I T N E S S E T H :

                  WHEREAS, Executive was previously a shareholder, officer and
director of PSI Communications, Inc. ("PSI");

                  WHEREAS, effective upon the filing of a Certificate of Merger
with the Secretary of State of Delaware, Vianet Access, Inc., a wholly owned
subsidiary of Vianet Technologies, Inc. ("Vianet"), merged into PSI (the
"Merger"), and PSI changeD its name to Vianet Access, Inc. ("Access"), pursuant
to the terms and provisions of an Agreement and Plan of Merger dated December
30, 1999 herewith (the "Agreement of Merger"), by and among Vianet , Access,
PSI, GNS, Ltd., a Texas limited partnership and certain stockholders of PSI,
including Executive, whereupon the Company became a wholly owned subsidiary of
Vianet;

                  WHEREAS, Executive is a Principal Stockholder (as defined in
the Agreement of Merger) of PSI, and pursuant to the Agreement of Merger, will
sell all of his shares of PSI in exchange for shares of Vianet and other good
and sufficient consideration;

                  WHEREAS, the substantial benefits to be received by the
Executive as a Principal Stockholder of PSI and, following the Merger, a
stockholder of Vianet, are good and sufficient consideration to bind Executive
to those certain Company-protection provisions set forth in Sections 5 through 8
hereof;

                  WHEREAS, as a condition to consummation of the Merger, Vianet
has required Executive to enter into this Employment Agreement, and Vianet would
not have entered into the Agreement of Merger or consummate the Merger if it did
not have the benefit of the Company-protection provisions set forth in Sections
5 through 8 hereof; and

                  WHEREAS, based on the foregoing, Executive and the Company
desire to enter into this Employment Agreement setting forth the terms and
conditions of Executive's employment by the Company.

                  NOW, THEREFORE, in consideration of the respective covenants
and agreements of the parties contained herein, the parties hereto agree as
follows:

                  1. Employment Term. The Company hereby agrees to employ
Executive, and Executive hereby agrees to accept such employment, on the terms
and conditions set forth herein. The parties agree that the term of employment

                                      -69-
<PAGE>

shall commence as of the date hereof and will end one day immediately prior to
the second anniversary of the date hereof (the "Original Term"), unless
terminated earlier as provided for herein, provided, however, that the Original
Term and each subsequent renewal thereof shall be automatically extended on a
month-to-month basis ("Renewal Term") unless at least sixty (60) days but not
more than ninety (90) days prior to the end of the Original Term or the current
Renewal Term either party gives written notice to the other of its intent to
terminate the Agreement as of the end of the Original Term or Renewal Term, as
the case may be (the Original Term and any subsequent Renewal Term to be
referred herein, collectively, as the "Term").

                  2. Position and Duties.

                  (a) Upon the commencement of the Term, the Company shall
employ Executive as its Executive Vice President of Sales & Marketing during the

                  (b) Executive shall devote his best efforts and full business
time and attention to the diligent, faithful, efficient and competent
performance of his duties and responsibilities hereunder and will not engage in

injure the reputation of the Company or any corporation, limited liability
company, partnership, association or other entity directly or indirectly
controlling, controlled by or under common control with the Company (an
"Affiliate") in any way. Executive shall devote his best efforts and business
time exclusively to the advancement of the interests of the Company and its
Affiliates. Notwithstanding the above, Executive may serve as a director,
trustee, or advisor of other organizations, or engage in charitable, civic,
and/or governmental activities provided that such service and activities do not
interfere with Executive performing his duties under this Agreement. Executive
may also engage in personal activities, including, without limitation, personal
investments, provided that such activities do not interfere or conflict with his
performance of duties hereunder.

                  3. Termination.

                  (a) Death. This Agreement and Executive's employment hereunder
shall terminate upon the death of Executive.

                  (b) Cause. The Company may terminate this Agreement and
Executive's employment hereunder for Cause, as defined below, effective at the
times indicated below. For purposes of this Section 3(b) the term "Cause" shall

Agreement and failure to cure such breach within fifteen (15) days after receipt
of written notice thereof;

gross negligence in the performance of Executive's duties, or failure to abide
by instructions received from the Board of Directors of the Company or its

written notice thereof.

                           Termination under clauses (i), (ii) and (iv) above
shall be effective at the conclusion of the fifteen (15) day cure period without
further notice and termination under clause (iii) above shall be effective
immediately upon the occurrence of the conduct specified therein and without
prior notice.

                  (c) Incapacity. The Company may terminate this Agreement and
Executive's employment hereunder, immediately, and without prior notice, if, as
a result of Executive's incapacity due to physical or mental illness or injury,
Executive shall have been unable to perform adequately his duties as herein
provided for ninety (90) consecutive days or an aggregate of ninety (90) days
during any twelve (12) month period during the Term.

                  (d) Termination by Executive Without Cause. Executive may
terminate this Agreement, without cause, upon six (6) months prior written
notice to the Company; provided however, that during such six (6) month period,
Executive shall use his reasonable best efforts to assist the Company in finding
a qualified replacement. Such termination shall be effective upon expiration of
the six (6) month notice period.

                  (e) Termination by Executive for Cause. Executive may
terminate this Agreement and Executive's employment hereunder for Executive's
Cause, as defined below. "Executive's Cause" shall mean:

                  (i) a breach by the Company of any of the terms of this
Agreement and failure to cure such breach within fifteen (15) days after notice
thereof or

                  (ii) the working conditions afforded to the Executive are

                  (f) No Further Payments Upon Termination. Except as otherwise

provided, however, that Executive shall remain entitled to any unpaid
compensation and benefits accrued prior to such termination and to any expense
or reimbursement to which he was entitled at the date of such termination. In

                                      -71-
<PAGE>

addition to the foregoing, upon: (i) termination of this Agreement by Executive
pursuant to Section 3(e) above, or (ii) termination of this Agreement by the
Company for for any reason other than Cause, Executive shall be entitled to, and
the Company shall pay to Executive within five (5) days after such termination,
a lump sum payment equal to the lesser of six (6) months base salary or the base
salary payable to Executive during the remainder of the Original Term or then
current Renewal Term, as the case may be, plus any other amount(s) to which
Executive is entitled under this agreement under the Company's benefit plans and
arrangements or otherwise.

                  4. Compensation and Benefits.

                  (a) Base Salary. During the Term, the Company shall pay to
Executive as compensation for his services hereunder, salary at the rate of $
175,000.00 per annum, less appropriate deductions (including legally required
withholdings and elective deductions for participation in benefit programs) and
payable in accordance with the Company's general payroll practice. The Board of
Directors of the Company shall evaluate the Executive for merit increases in his
base salary hereunder at least annually, but shall not, in any event, reduce
Executive's base salary during the Term.

                  (b) Benefits and Perquisites. Executive shall be entitled to
participate in or receive benefits under any pension, savings, life insurance,

plans or arrangements.

                  (c) Expenses. During the Term, Executive shall be entitled to

properly accounts therefor in accordance with Company policy and applicable law.

                  (d) Vacations. Executive shall be entitled to paid vacations
and holidays in accordance with Company policy in effect from time to time;

                  5. Agreement Not to Compete.

                  Executive agrees during the Term and that in the event of
separation as outlined in Section 3, Executive shall not for a period of two (2)
years after termination, directly or indirectly, engage in or conduct, be
employed directly or indirectly by, serve as an officer or director of, hold an
equity interest in, or provide advice or act as a consultant to, any person or
entity which is, or is about to be engaged, in any business which is directly
competitive with the business of the Company or its Affiliates (a "Competitive
Business"); provided that, nothing herein shall prohibit Executive from owning
not more than five percent (5%) of the outstanding capital stock of any Company
listed on a national securities exchange so long as Executive is otherwise not
in breach of the covenants set forth above; and provided further, that this
section 5 shall not apply if the Executive terminates this agreement pursuant to
Section 3 (e). Executive acknowledges and agrees that because the Company is in
the communications technology business, its market is geographically broad. As
such, the Executive acknowledges and agrees that his agreement not to compete
prohibits the Executive from engaging in a Competitive Business anywhere in the
world. In the event a court of competent jurisdiction determines that this
provision is not enforceable by its terms for lack of a geographical area, the
parties agree to request such court to modify this provision to include a
reasonable geographical area. The parties do not intend that this provision be
deemed unenforceable for lack of a specified geographical area.

                  6. Non-Solicitation. Executive agrees that during the Term,
and for a period of two (2) years after the expiration or termination of this
Agreement and Executive's employment hereunder, regardless of the reason for
termination of employment, Executive shall not:

                  (i) directly or indirectly, solicit any person, corporation,
limited liability company, partnership or other business entity which is, at the
time of such solicitation, or was, within the prior year, a customer, client or
licensee of the Company or of any Affiliate, (x) for the purpose of engaging
with any such customer in any business transactions of the nature presently
performed by, or the business (or any part thereof) presently conducted by, the
Company or any Affiliate, or (y) for the purpose of engaging with any such
customer in any business transactions of the nature performed by, or the
business (or any part thereof) conducted by the Company, or any Affiliate, at
any time during the Term;

                  (ii) directly or indirectly solicit, induce, influence,
request or advise any customer, client or licensee of the Company or any
Affiliate to withdraw, curtail, cancel, discontinue, reduce or modify such
customer's, client's or licensee's business or business relationship with the
Company or any Affiliate; or

                  (iii) directly or indirectly employ, solicit for employment or
advise, or recommend to any other person that he employ or solicit for
employment, any person employed at that time, or at any time during the prior
year, by the Company or an Affiliate.

                  (a) During the Term and thereafter, Executive shall not,
without the written consent of the Board of Directors of the Company, disclose
or use (except in the course of his employment hereunder and in furtherance of
the business of the Company or an Affiliate) any Confidential Information of the
Company, or any Affiliate. "Confidential Information" shall mean all
confidential information, proprietary data and trade secrets of the Company and
its Affiliates including, without limitation, the following: the identity,
written lists, or descriptions of any customers or referral sources, financial
statements, cost reports, or other financial information; contract proposals or
bidding information; business plans; marketing plans; budgets; projections;

sales data; management systems, policies or procedures, including related forms
and manuals; concepts; ideas; drawings; discoveries; inventions; processes;
designs; formulas; programs; computer programs; object code; source code;
engineering tolerances; know-how; and product developments. Notwithstanding the
foregoing, Confidential Information shall not include information concerning the
Company, or its Affiliates, known to Executive which (i) becomes public
knowledge (other than by acts by Executive or his representatives in violation
of this Agreement), (ii) becomes known to Executive on a non-confidential basis
from a source other than the Company, provided that such source is not known or
should not reasonably have been known by Executive to be bound by a
confidentiality agreement with or other obligation of secrecy to the Company, or
(iii) Executive is required to disclose in a judicial, administrative or
governmental proceeding (a "Legal Proceeding"). In the event Executive is
requested to disclose Confidential Information in a Legal Proceeding as
contemplated by clause (iii) of the previous sentence, Executive shall provide
the Company with prompt notice of such request so that the Company may timely
seek an appropriate protective order or waive compliance with this Section 7.
If, after giving such notice, and in the absence of a protective order or the
receipt of a waiver hereunder, Executive is, in the opinion of his legal counsel
compelled to disclose such information to any tribunal or else stand liable for
contempt or other censure or penalty, then Executive may disclose such
information to such tribunal, to the extent so required without liability
hereunder.

                  (b) Executive agrees that upon expiration or termination of
this Agreement and Executive's employment hereunder, regardless of the reason
for termination, he will immediately return to the Company any and all physical
manifestations of Confidential Information and all copies of the same, and
Confidential Information of any customers of the Company and its Affiliates,
within his possession, and will not at any time thereafter copy or reproduce the
same.

                  8. Inventions and Pending Patent Applications. (a) Executive
agrees that all inventions, designs, improvements, writings, and discoveries
(collectively, "Inventions") made during the Term and pertaining to the business
conducted by the Company shall be the exclusive property of the Company.
Executive hereby transfers and assigns to the Company all right, title and
interest in and to the Inventions, including any and all domestic and foreign
patent rights therein and any renewals thereof. Executive shall assist the
Company in obtaining patents and copyrights on all Inventions deemed suitable
for patent or copyright by the Company and shall execute all documents and do
all things necessary to obtain letters patent or copyrights, as the case may be,
to vest the Company with full and exclusive title thereto, and to protect the
same against infringements by others.

                                      -74-

                  (b) Executive agrees to execute and deliver all applications
for patent, including all divisional, continuation, reissue and other
applications for patent on the invention(s) set forth in the pending
applications listed in Section 4(l)(iii) of the Disclosure Schedule to the
Agreement of Merger and all assignments thereof to the Company, Vianet or their
assigns, to communicate to the Company, Vianet or their representatives all
facts known to Executive respecting said invention(s), whenever requested, to
testify in any interference's or other legal proceedings in which any of said
applications or patents resulting therefrom may become involved, to sign all
lawful papers, make all rightful oaths, and to do generally everything

and nominees to obtain patent protection for said invention(s) in the United
States and all other countries, all at the cost and expense of the Company and
Vianet.

                  9. Successors and Assigns. This Agreement is personal in
nature and Executive may not assign or transfer this Agreement or any right or
obligation hereunder to any other person. The Company, however, may assign or
transfer this Agreement and any of its rights or obligations hereunder to any
Affiliate or Successor Corporation or entity without the consent of Executive.
Any purported assignment in violation of the terms hereof shall be void and of
no effect. This Agreement and all rights hereunder shall inure to the benefit of
and be enforceable by Executive, the Company and the Company's successors and
assigns.

                  10. Notice. Notices and all other communications required or

obligation imposed upon Executive hereunder may be waived only upon the written

                         EXECUTIVE EMPLOYMENT AGREEMENT

                  EXECUTIVE EMPLOYMENT AGREEMENT dated as of January 1, 2000 by
and between VIANET ACCESS, INC, a Delaware corporation (formerly known as PSI
COMMUNICATIONS, INC., a Delaware Corporation), with its principal office at 3415
Custer Road (Suite 101), Plano, Texas 75023 (the "Company"), and Michael
Pearson, residing at 2013 Tiehack Lane, Garland, Texas 75044 ("Executive").

                              W I T N E S S E T H :

                  WHEREAS, Executive was previously a shareholder, officer and
director of PSI Communications, Inc. ("PSI");

                  WHEREAS, effective upon the filing of a Certificate of Merger
with the Secretary of State of Delaware, Vianet Access, Inc., a wholly owned
subsidiary of Vianet Technologies, Inc. ("Vianet"), merged into PSI (the
"Merger"), and PSI changeD its name to Vianet Access, Inc. ("Access"), pursuant
to the terms and provisions of an Agreement and Plan of Merger dated December
30, 1999 herewith (the "Agreement of Merger"), by and among Vianet , Access,
PSI, GNS, Ltd., a Texas limited partnership and certain stockholders of PSI,
including Executive, whereupon the Company became a wholly owned subsidiary of
Vianet;

                  WHEREAS, Executive is a Principal Stockholder (as defined in
the Agreement of Merger) of PSI, and pursuant to the Agreement of Merger, will
sell all of his shares of PSI in exchange for shares of Vianet and other good
and sufficient consideration;

                  WHEREAS, the substantial benefits to be received by the
Executive as a Principal Stockholder of PSI and, following the Merger, a
stockholder of Vianet, are good and sufficient consideration to bind Executive
to those certain Company-protection provisions set forth in Sections 5 through 8
hereof;

                  WHEREAS, as a condition to consummation of the Merger, Vianet
has required Executive to enter into this Employment Agreement, and Vianet would
not have entered into the Agreement of Merger or consummate the Merger if it did
not have the benefit of the Company-protection provisions set forth in Sections
5 through 8 hereof; and

                  WHEREAS, based on the foregoing, Executive and the Company
desire to enter into this Employment Agreement setting forth the terms and
conditions of Executive's employment by the Company.

                  NOW, THEREFORE, in consideration of the respective covenants
and agreements of the parties contained herein, the parties hereto agree as
follows:

                  1. Employment Term. The Company hereby agrees to employ
Executive, and Executive hereby agrees to accept such employment, on the terms
and conditions set forth herein. The parties agree that the term of employment

                                      -80-
<PAGE>

shall commence as of the date hereof and will end one day immediately prior to
the second anniversary of the date hereof (the "Original Term"), unless
terminated earlier as provided for herein, provided, however, that the Original
Term and each subsequent renewal thereof shall be automatically extended on a
month-to-month basis ("Renewal Term") unless at least sixty (60) days but not
more than ninety (90) days prior to the end of the Original Term or the current
Renewal Term either party gives written notice to the other of its intent to
terminate the Agreement as of the end of the Original Term or Renewal Term, as
the case may be (the Original Term and any subsequent Renewal Term to be
referred herein, collectively, as the "Term").

                  2. Position and Duties.

                  (a) Upon the commencement of the Term, the Company shall
employ Executive as its Vice President of Engineering during the term. Executive
shall fulfill such duties and responsibilities as are consistent with such
position and as are assigned to him from time to time by the Board of Directors
of the Company or its delegate.

                  (b) Executive shall devote his best efforts and full business
time and attention to the diligent, faithful, efficient and competent
performance of his duties and responsibilities hereunder and will not engage in
any other ventures or enterprises. Executive shall at all times comport himself
in such manner that his conduct will not reasonably be expected to prejudice or
injure the reputation of the Company or any corporation, limited liability
company, partnership, association or other entity directly or indirectly
controlling, controlled by or under common control with the Company (an
"Affiliate") in any way. Executive shall devote his best efforts and business
time exclusively to the advancement of the interests of the Company and its
Affiliates. Notwithstanding the above, Executive may serve as a director,
trustee, or advisor of other organizations, or engage in charitable, civic,
and/or governmental activities provided that such service and activities do not
interfere with Executive performing his duties under this Agreement. Executive
may also engage in personal activities, including, without limitation, personal
investments, provided that such activities do not interfere or conflict with his
performance of duties hereunder.

                  3. Termination.

                  (a) Death. This Agreement and Executive's employment hereunder
shall terminate upon the death of Executive.

                  (b) Cause. The Company may terminate this Agreement and
Executive's employment hereunder for Cause, as defined below, effective at the
times indicated below. For purposes of this Section 3(b) the term "Cause" shall

Agreement and failure to cure such breach within fifteen (15) days after receipt
of written notice thereof;









                                      -81-

breach within fifteen (15) days after written receipt of notice thereof;

                  (iii) Willful misconduct, dishonesty, alcoholism, addiction to

engaging in any discrimination or sexual harassment of employees of the Company
or of customers or vendors of the Company;

                  (iv) Persistent incompetence or inefficiency, habitual or
gross negligence in the performance of Executive's duties, or failure to abide
by instructions received from the Board of Directors of the Company or its
delegate or the violation of policies and practices adopted by the Company or
Vianet, and failure to cure the same within fifteen (15) days after receipt of
written notice thereof.

                  Termination under clauses (i), (ii) and (iv) above shall be
effective at the conclusion of the fifteen (15) day cure period without further
notice and termination under clause (iii) above shall be effective immediately
upon the occurrence of the conduct specified therein and without prior notice.

                  (c) Incapacity. The Company may terminate this Agreement and
Executive's employment hereunder, immediately, and without prior notice, if, as
a result of Executive's incapacity due to physical or mental illness or injury,
Executive shall have been unable to perform adequately his duties as herein
provided for ninety (90) consecutive days or an aggregate of ninety (90) days
during any twelve (12) month period during the Term.

                  (d) Termination by Executive Without Cause. Executive may
terminate this Agreement, without cause, upon six (6) months prior written
notice to the Company; provided however, that during such six (6) month period,
Executive shall use his reasonable best efforts to assist the Company in finding
a qualified replacement. Such termination shall be effective upon expiration of
the six (6) month notice period.

                  (e) Termination by Executive for Cause. Executive may
terminate this Agreement and Executive's employment hereunder for Executive's
Cause, as defined below. "Executive's Cause" shall mean:

                  (i) a breach by the Company of any of the terms of this
Agreement and failure to cure such breach within fifteen (15) days after notice
thereof or

                  (ii) the working conditions afforded to the Executive are
habitually and grossly intolerable and such conditions are not cured within (15)
days after notice thereof;

                  (f) No Further Payments Upon Termination. Except as otherwise
provided below, upon any termination enumerated in this Paragraph 3, Executive's
right to further compensation and benefits under this Agreement shall cease,
provided, however, that Executive shall remain entitled to any unpaid
compensation and benefits accrued prior to such termination and to any expense
or reimbursement to which he was entitled at the date of such termination. In

                                      -82-
<PAGE>

addition to the foregoing, upon: (i) termination of this Agreement by Executive
pursuant to Section 3(e) above, or (ii) termination of this Agreement by the
Company for for any reason other than Cause, Executive shall be entitled to, and
the Company shall pay to Executive within five (5) days after such termination,
a lump sum payment equal to the lesser of six (6) months base salary or the base
salary payable to Executive during the remainder of the Original Term or then
current Renewal Term, as the case may be, plus any other amount(s) to which
Executive is entitled under this agreement under the Company's benefit plans and
arrangements or otherwise.

                  4. Compensation and Benefits.

                  (a) Base Salary. During the Term, the Company shall pay to
Executive as compensation for his services hereunder, salary at the rate of $
125,000.00 per annum, less appropriate deductions (including legally required
withholdings and elective deductions for participation in benefit programs) and
payable in accordance with the Company's general payroll practice. The Board of
Directors of the Company shall evaluate the Executive for merit increases in his
base salary hereunder at least annually, but shall not, in any event, reduce
Executive's base salary during the Term.

                  (b) Benefits and Perquisites. Executive shall be entitled to
participate in or receive benefits under any pension, savings, life insurance,
health and accident plan or other arrangement which is from time to time made

basis consistent with the terms, conditions and overall administration of such
plans or arrangements.

                  (c) Expenses. During the Term, Executive shall be entitled to
receive reimbursement for reasonable expenses actually incurred by him in the
performance of his duties hereunder (in accordance with the policies and
procedures established by the Board of Directors of the Company), provided that
any such expenses shall be reimbursable only to the extent that Executive
properly accounts therefor in accordance with Company policy and applicable law.

                  (d) Vacations. Executive shall be entitled to paid vacations
and holidays in accordance with Company policy in effect from time to time;

                  5. Agreement Not to Compete.

                  Executive agrees during the Term and that in the event of
separation as outlined in Section 3, Executive shall not for a period of two (2)
years after termination, directly or indirectly, engage in or conduct, be
employed directly or indirectly by, serve as an officer or director of, hold an
equity interest in, or provide advice or act as a consultant to, any person or
entity which is, or is about to be engaged, in any business which is directly
competitive with the business of the Company or its Affiliates (a "Competitive
Business"); provided that, nothing herein shall prohibit Executive from owning
not more than five percent (5%) of the outstanding capital stock of any Company
listed on a national securities exchange so long as Executive is otherwise not
in breach of the covenants set forth above; and provided further, that this
section 5 shall not apply if the Executive terminates this agreement pursuant to
Section 3 (e). Executive acknowledges and agrees that because the Company is in
the communications technology business, its market is geographically broad. As
such, the Executive acknowledges and agrees that his agreement not to compete
prohibits the Executive from engaging in a Competitive Business anywhere in the
world. In the event a court of competent jurisdiction determines that this
provision is not enforceable by its terms for lack of a geographical area, the
parties agree to request such court to modify this provision to include a
reasonable geographical area. The parties do not intend that this provision be
deemed unenforceable for lack of a specified geographical area.

                  6. Non-Solicitation. Executive agrees that during the Term,
and for a period of two (2) years after the expiration or termination of this
Agreement and Executive's employment hereunder, regardless of the reason for
termination of employment, Executive shall not:

                  (i) directly or indirectly, solicit any person, corporation,
limited liability company, partnership or other business entity which is, at the
time of such solicitation, or was, within the prior year, a customer, client or
licensee of the Company or of any Affiliate, (x) for the purpose of engaging
with any such customer in any business transactions of the nature presently
performed by, or the business (or any part thereof) presently conducted by, the
Company or any Affiliate, or (y) for the purpose of engaging with any such
customer in any business transactions of the nature performed by, or the
business (or any part thereof) conducted by the Company, or any Affiliate, at
any time during the Term;

                  (ii) directly or indirectly solicit, induce, influence,
request or advise any customer, client or licensee of the Company or any
Affiliate to withdraw, curtail, cancel, discontinue, reduce or modify such
customer's, client's or licensee's business or business relationship with the
Company or any Affiliate; or

                  (iii) directly or indirectly employ, solicit for employment or
advise, or recommend to any other person that he employ or solicit for
employment, any person employed at that time, or at any time during the prior
year, by the Company or an Affiliate.

                  7. Non-disclosure.

                  (a) During the Term and thereafter, Executive shall not,
without the written consent of the Board of Directors of the Company, disclose
or use (except in the course of his employment hereunder and in furtherance of
the business of the Company or an Affiliate) any Confidential Information of the
Company, or any Affiliate. "Confidential Information" shall mean all
confidential information, proprietary data and trade secrets of the Company and
its Affiliates including, without limitation, the following: the identity,
written lists, or descriptions of any customers or referral sources, financial
statements, cost reports, or other financial information; contract proposals or
bidding information; business plans; marketing plans; budgets; projections;
training and operations methods and manuals; personnel records; fee structures;
sales data; management systems, policies or procedures, including related forms
and manuals; concepts; ideas; drawings; discoveries; inventions; processes;
designs; formulas; programs; computer programs; object code; source code;
engineering tolerances; know-how; and product developments. Notwithstanding the
foregoing, Confidential Information shall not include information concerning the
Company, or its Affiliates, known to Executive which (i) becomes public
knowledge (other than by acts by Executive or his representatives in violation
of this Agreement), (ii) becomes known to Executive on a non-confidential basis
from a source other than the Company, provided that such source is not known or
should not reasonably have been known by Executive to be bound by a
confidentiality agreement with or other obligation of secrecy to the Company, or
(iii) Executive is required to disclose in a judicial, administrative or
governmental proceeding (a "Legal Proceeding"). In the event Executive is
requested to disclose Confidential Information in a Legal Proceeding as
contemplated by clause (iii) of the previous sentence, Executive shall provide
the Company with prompt notice of such request so that the Company may timely
seek an appropriate protective order or waive compliance with this Section 7.
If, after giving such notice, and in the absence of a protective order or the
receipt of a waiver hereunder, Executive is, in the opinion of his legal counsel
compelled to disclose such information to any tribunal or else stand liable for
contempt or other censure or penalty, then Executive may disclose such
information to such tribunal, to the extent so required without liability
hereunder.

                  (b) Executive agrees that upon expiration or termination of
this Agreement and Executive's employment hereunder, regardless of the reason
for termination, he will immediately return to the Company any and all physical
manifestations of Confidential Information and all copies of the same, and
Confidential Information of any customers of the Company and its Affiliates,
within his possession, and will not at any time thereafter copy or reproduce the
same.

                  8. Inventions and Pending Patent Applications. (a) Executive
agrees that all inventions, designs, improvements, writings, and discoveries
(collectively, "Inventions") made during the Term and pertaining to the business
conducted by the Company shall be the exclusive property of the Company.
Executive hereby transfers and assigns to the Company all right, title and
interest in and to the Inventions, including any and all domestic and foreign
patent rights therein and any renewals thereof. Executive shall assist the
Company in obtaining patents and copyrights on all Inventions deemed suitable
for patent or copyright by the Company and shall execute all documents and do
all things necessary to obtain letters patent or copyrights, as the case may be,
to vest the Company with full and exclusive title thereto, and to protect the
same against infringements by others.

                                      -85-
<PAGE>

         (b) Executive agrees to execute and deliver all applications for
patent, including all divisional, continuation, reissue and other applications
for patent on the invention(s) set forth in the pending applications listed in
Section 4(l)(iii) of the Disclosure Schedule to the Agreement of Merger and all
assignments thereof to the Company, Vianet or their assigns, to communicate to
the Company, Vianet or their representatives all facts known to Executive
respecting said invention(s), whenever requested, to testify in any
interference's or other legal proceedings in which any of said applications or
patents resulting therefrom may become involved, to sign all lawful papers, make
all rightful oaths, and to do generally everything reasonably necessary to
assist the Company, Vianet, their successors, assigns and nominees to obtain
patent protection for said invention(s) in the United States and all other
countries, all at the cost and expense of the Company and Vianet.

                  9. Successors and Assigns. This Agreement is personal in
nature and Executive may not assign or transfer this Agreement or any right or
obligation hereunder to any other person. The Company, however, may assign or
transfer this Agreement and any of its rights or obligations hereunder to any
Affiliate or Successor Corporation or entity without the consent of Executive.
Any purported assignment in violation of the terms hereof shall be void and of
no effect. This Agreement and all rights hereunder shall inure to the benefit of
and be enforceable by Executive, the Company and the Company's successors and
assigns.

                  10. Notice. Notices and all other communications required or
