ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On October 12, 1999, Vianet Technologies,  Inc. (the "Company")  consummated its
acquisition of all of the issued and outstanding stock of Infinop Holdings, Inc.
("Infinop"),  in exchange for the  issuance of up to 1,495,454  shares of Common
Stock of the Company. The transaction was completed in accordance with the terms
of the  Agreement  and Plan of Merger,  dated August 31, 1999,  by and among the
Company,  Vianet Labs, Inc., a Delaware  corporation ("Vianet Labs"), which is a
wholly-owned  subsidiary of the Company,  Infinop and Paul Fisher, Howard Fisher
and Craig Fisher (collectively, the "Principal Stockholders").

Infinop is engaged, through its subsidiaries,  Computer and Information Science,
Inc.,  and INFInet Op.,  Inc., in the business of developing  and marketing data
compression and pattern  recognition  software.  Its key products,  all of which
incorporate its proprietary wavelet technology,  are Lightning Strike, a product
designed  to  effectuate  still  imagery  compression,  LSVideoN  and  LSVideoR,
products  designed to  effectuate  video or moving image  processing,  LSBio,  a
product that facilitates the compression of scanned documents for long-term data
storage,  and LSStorm,  a product that  reduces the bulk of  information  moving
through a network.

As a  result  of the  completion  of this  transaction,  Infinop  has  become  a
wholly-owned  subsidiary of Vianet and all of the outstanding  shares of Infinop
Common Stock have been  cancelled and converted  into shares of Vianet's Class A
Common  Stock,  par value  $0.001  per share (the  "Vianet  Common  Stock").  In
addition,  the  Infinop  shareholders  have  the  right  to  receive  additional
consideration in the form of shares of common stock of the Company (or, upon the
election  of the  Principal  Stockholders,  in the  form of cash,  subject  to a
maximum  cash  limit  of  $3,200,000)  (the  "Additional  Consideration").   The
Additional  Consideration will be based on royalties actually received by Vianet
during the four year period (the  "Additional  Payment  Period")  following  the
closing of the  Merger  (the  "Closing")  under the terms of the  following  two
Software License  Agreements:  (i) the Software License Agreement dated June 25,
1998 between Infinop Op, Inc. and Video Stream International (now doing business
as  "Teraglobal")  (the  "Teraglobal  Contract");  and (ii) the Software License
Agreement  dated October 15, 1998 between  Infinop Op, Inc. and Transwire,  Inc.
(now doing business as "Prism") (the "Prism Contract").

The Additional  Consideration  payable in respect of each  outstanding  share of
Infinop  Common  Stock will  represent  each share's pro rata portion of a fixed
percentage  of the  cumulative  royalties  in excess of $4 million  received  by
Vianet during the Additional  Payment  Period.  The percentage  upon which those
payments  will be based  will  represent  the  aggregate  of 50% of the  royalty
received from the  Teraglobal  Contract and 40% of the royalties  received under
the Prism Contract.  All Additional  Consideration  will be payable in shares of
Vianet Common Stock,  unless the  Principal  Stockholders  elect to receive cash
(subject  to an  aggregate  limit  of $3.2  million  in  cash).  The  Additional
Consideration  payable in respect of each share of Infinop  Common Stock will be
distributed  within  30  days  of the  end of  each  annual  period  during  the
Additional  Payment Period.  For purposes of determining the number of shares of
Vianet Common Stock payable as Additional Consideration, the Vianet Common Stock
will be valued at the average  closing price of Vianet Common Stock for the five
trading days immediately preceding the end of the related annual period.

ADJUSTMENT TO MERGER CONSIDERATION; ESCROW

If the net worth of Infinop as of the effective  date of the Merger is less than
the net worth of Infinop as of June 30, 1999, the consideration  received by the
Infinop  stockholders in connection with the Merger is required to be reduced by
the amount of such deficit,  subject to a maximum  adjustment  equal to 1.50% of
the aggregate  number of shares of Vianet Common Stock (the  "Adjustment  Escrow
Shares") issued to each Infinop  stockholder in exchange for outstanding  shares
of Infinop  Common Stock upon  completion of the Merger.  In order to effectuate
any such  adjustment,  the  Adjustment  Escrow Shares have been  deposited  with
CitiBank,  N.A.,  as escrow  agent (the  "Escrow  Agent"),  to be held in escrow
pursuant to the Escrow Agreement  described below (the "Escrow  Agreement").  In
addition,  1.50% of the  aggregate  number of Vianet  Common Stock to which each
holder of a convertible  debenture  previously issued by Infinop would otherwise
be  entitled  upon  conversion  after the closing of the Merger and 1.50% of the
shares of Vianet Common Stock to which each holder of options previously granted
by Vianet would otherwise be entitled to receive upon exercise after the closing
of the Merger have been  deposited  with the Escrow Agent pursuant to the Escrow
Agreement to hold in escrow as additional Escrow Adjustment  Shares. If there is
a deficit  between  the net worth of  Infinop  as of the  effective  date of the
Merger  and the net worth of Infinop as of June 30,  1999,  the Escrow  Agent is
required to deliver to Vianet out of the Adjustment  Escrow Shares the number of
Adjustment Escrow Shares having a value equal to such deficit. For this purpose,
the Adjustment  Escrow Shares will be valued at $7.00 per share.  Any Adjustment
Escrow Shares  remaining  after such  adjustment will be delivered to the former
stockholders of Infinop proportionately.

ESCROW AGREEMENT

As a condition to the closing of the Merger, Vianet, the Principal Stockholders,
in their individual capacities, the Principal Stockholders, in their capacity as
Stockholders'  Agents, and Citibank,  N.A., as the escrow agent, entered into an
Escrow  Agreement  to  provide  for,  among  other  things,  the  escrow  of the
Adjustment  Escrow Shares.  The Adjustment  Escrow Shares will be held in escrow
until any  adjustment  required  by the Merger  Agreement  to the  consideration
received by the Infinop  stockholders  in connection  with the Merger is finally
determined.  Pursuant to the terms of the Escrow Agreement,  Citibank, N.A. will
hold and safeguard the  Adjustment  Escrow Shares and,  after any  adjustment is
finally  determined,  deliver to the former Infinop  stockholders that number of
Adjustment  Escrow  Shares  held in escrow in  excess  of any  shares  which are
required to satisfy any adjustment.


<PAGE>
TREATMENT OF OPTIONS TO PURCHASE INFINOP COMMON STOCK

In addition to the  foregoing,  in accordance  with the provisions of the Merger
Agreement, Vianet has agreed to issue option to purchase an aggregate of 598,284
shares of its Common  Stock in exchange  for options to purchase an aggregate of
2,727,410  shares of Infinop  common  stock  which were  issued  pursuant to the
Infinop  Stock  Option  Plan.  Each such  option so assumed by Vianet  under the
Merger  Agreement  shall continue to have, and be subject to, the same terms and
conditions  set forth in Infinop's  Stock Option Plan and the  applicable  stock
option agreement  immediately  prior to the Effective Time, except that (i) such
option will be  exercisable  for a number of shares of Vianet Common Stock equal
to the  product  of the  number of  shares of  Infinop  Common  Stock  that were
issuable upon exercise of such option  immediately  prior to the Effective  Time
multiplied  by 0.21936 (as adjusted as  described  below,  the "Option  Exchange
Ratio")  and  rounded to the  nearest  whole  number of shares of Vianet  Common
Stock,  and (ii) the per share  exercise  price for the shares of Vianet  Common
Stock  issuable  upon  exercise  of such  assumed  option  will be  equal to the
quotient  determined by dividing the exercise  price per share of Infinop Common
Stock at which such option was  exercisable  immediately  prior to the Effective
Time by the Option Exchange Ratio. If Adjustment  Escrow Shares are delivered to
Vianet as a result of a deficit in net worth (as described under  "Adjustment to
Merger  Consideration;  Escrow") then the Option Exchange Ratio will be adjusted
to equal the actual rate at which Infinop  Common Stock is converted into Vianet
Common Stock after such adjustment.

TREATMENT OF CONVERTIBLE DEBENTURES

In addition,  Vianet has agreed to issue  312,587  shares of its Common Stock to
the holders of an aggregate of $950,000 principal amount outstanding convertible
debentures  previously  issued by Infinop,  should such holders elect to convert
such convertible  debenture (on the terms and conditions  specified in each such
convertible  debenture).  Such  number of shares is  subject to  adjustment  for
interest payable on the convertible  debentures and to subsequent  adjustment as
provided in each of such convertible debentures. If Adjustment Escrow Shares are
delivered  to Vianet as a result of a deficit in net worth (as  described  under
"Adjustment  to Merger  Consideration;  Escrow") then the  Debenture  Conversion
Ratio will be adjusted to equal the actual rate at which Infinop Common Stock is
converted into Vianet Common Stock after such adjustment.

RESTRICTIONS ON TRANSFERABILITY OF VIANET COMMON STOCK; REGISTRATION
RIGHTS AGREEMENT

Initially, the shares of Vianet Common Stock to be issued in connection with the
Merger or issuable upon exercise of Infinop stock options or upon  conversion of
convertible  debentures will not be registered or freely  tradeable  securities.
Pursuant to the Merger Agreement, no Vianet Common Stock received by the Infinop
stockholders  in the  Merger  will be  transferable  during the first six months
after the Merger.  Thereafter, the restrictions on transfer of the Vianet Common
Stock received by the Infinop stockholders in connection with the Merger will be
phased out as  follows:  (a) 25% of the Vianet  Common  Stock  received  will be
transferable  without  reference to the restrictions on  transferability  in the
Merger  Agreement  six months  after the  effective  date of the Merger;  (b) an
additional 25% of the Vianet Common Stock received will be transferable  without
reference to the restrictions on  transferability in the Merger Agreement twelve

<PAGE>
months  after the  effective  date of the Merger;  and (c) the  remainder of the
Vianet  Common Stock  received  will be  transferable  without  reference to the
restrictions  on  transferability  in the Merger  Agreement  24 months after the
effective  date of the  Merger;  provided,  however,  that the  restrictions  on
transfer  applicable to Vianet Common Stock received by the holders of Infinop's
8% convertible  debentures due August 17, 1999 converted prior to the Merger and
who vote in favor of the Merger will be phased out as  follows:  (1) 50% of such
shares of Vianet  Common Stock will be  transferable  without  reference to such
restrictions  six  months  after the  effective  date of the  Merger and (2) the
remaining  50% of such shares of such Vianet  Common Stock will be  transferable
without reference to such restriction  twelve months after the effective date of
the Merger.  Vianet has entered into a Registration  Rights  Agreement with Paul
Fisher, Craig Fisher and Howard Fisher whereby Vianet has agreed to register the
resale  of the  Vianet  Common  Stock  issued  in  connection  with the  Merger,
including any shares  issued upon the exercise of any options  issued by Infinop
assumed by Vianet and any shares issued upon the  conversion of any  convertible
debenture  previously  issued by Infinop,  under the  Securities Act of 1933, as
amended,  and applicable state  securities laws,  within 180 days of the closing
and also upon the demand by the holders of at least 25% of such shares of Vianet
Common  Stock.  However,  Vianet is  obligated  to effect  only four such demand
registrations.  Vianet is also obligated (x) to register the Vianet Common Stock
in connection  with any offering  initiated by Vianet,  subject to limitation to
the extent that the  inclusion  of such shares would  jeopardize  the success of
Vianet's offering, (y) register for resale all Vianet Common Stock issuable upon
the  exercise  of any Infinop  options  assumed by Vianet on Form S-8 as soon as
Vianet is  eligible  to use such form,  and (z)  register  for resale all Vianet
Common  Stock  issued in  connection  with the Merger on Form S-3 within 30 days
after Vianet becomes  eligible to use such form.  All costs of any  registration
will be borne by Vianet.  However,  the selling stockholders will be required to
pay all  underwriting  and  sales  discounts  and  commissions.  Vianet  will be
obligated to pay certain  liquidated damages in the event that it fails to honor
its registration obligations under the Registration Rights Agreement.

BOARD REPRESENTATION

Vianet has agreed that for so long as the Principal Stockholders continue to own
at least 10 percent of the issued and  outstanding  Vianet Common Stock, at each
annual meeting of shareholders of Vianet,  Vianet's  nominating  committee shall
nominate one candidate for director selected by the nominating  committee from a
list of  three  candidates  proposed  by the  Principal  Stockholders,  and that
management shall recommend the election of such candidate.

     (5)  CONVERSION  OF INFINOP  SHARES.  At and as of the  Effective  Time, by
virtue of the Merger and without  any action on the part of any party  hereto or
any holder of Infinop Shares,  (A) each Infinop Share (other than any Dissenting
Share) shall be converted into the right to receive .21936 Vianet Shares, a cash
payment in lieu of fractional Vianet Shares (which, for purposes of this Section
2(d)(v)  shall  be  valued  at $7.00  per  share),  and a pro rata  share of the
Additional  Payments  to be  determined  pursuant  to  Section  2A (THE  "MERGER
CONSIDERATION")  (THE  RATIO OF .21936  VIANET  SHARES TO ONE  INFINOP  SHARE IS
REFERRED TO HEREIN AS THE  "CONVERSION  RATIO") (B) all Infinop  Shares shall no
longer be  outstanding  or issuable  and shall be canceled and retired and shall
cease to exist,  and each  holder  thereof  shall  thereafter  cease to have any
rights with respect to such Infinop Shares,  and (C) each Dissenting Share shall
be converted  into the right to receive  payment from the Surviving  Corporation
with respect thereto in accordance  with the PROVISIONS OF THE DELAWARE  GENERAL
CORPORATION LAW, PROVIDED,  HOWEVER,  that the Conversion Ratio shall be subject
to equitable adjustment in the event of any stock split, stock dividend, reverse
stock split,  of the Infinop  Shares or the Vianet  Shares after the date hereof
but  prior to the  Effective  Time.  No  Infinop  Share  shall be  deemed  to be
outstanding  or to have any  rights  other  than  those set forth  above in this
Section 2(d)(v) after the Effective Time.

     (6)  CONVERSION OF CAPITAL STOCK OF LABS. At and as of the Effective  Time,
each share of Common Stock,  without par value,  of Labs shall be converted into
one share of Common Stock, without par value, of Infinop.

     (7) CONVERTIBLE  DEBENTURES.  At and as of the Effective Time,  pursuant to
the  provisions  of (1) each of the 8%  convertible  debentures  of Infinop  due
September  30, 2002 in the  aggregate  principal  amount of  $175,000  issued to
Richard Abrahams and Gerald Mizel  outstanding at the Effective Time, (2) the 6%
convertible  debentures  of Infinop  due  September  30,  2002 in the  aggregate
principal  amount of  $950,000  issued to ANDA  Partnership  outstanding  at the
Effective  Time and (3) each of the 8%  convertible  debentures  of Infinop  due
August 17, 1999 in the  aggregate  principal  amount of  $750,000  issued to the
holders  thereof set forth on SCHEDULE  2(D)(VII)  OUTSTANDING  AT THE EFFECTIVE
TIME (COLLECTIVELY, THE "CONVERTIBLE DEBENTURES"), each holder of an outstanding
Convertible Debenture shall have the right to receive upon the conversion of the
Convertible  Debenture  (on the  terms  and  conditions  specified  in each such
Convertible  Debenture),  after the Effective  Time, the number of Vianet Shares
determinable  by multiplying (x) the number of Infinop Shares issuable upon such
conversion  immediately  prior to the Effective  Time plus the number of Infinop
Shares that would have been issuable upon a conversion of interest accrued after
the Effective Time by (y) the Conversion Ratio, subject to subsequent adjustment
as provided in Section 8(a) of each of the Convertible Debentures.  For purposes
of this Section 2(d)(vii),  the Conversion Ratio shall be adjusted if Adjustment
Escrow  Shares  (as  defined  below)  are  delivered  to Vianet as a result of a
reduction in the Merger Consideration  pursuant to Section 2(d)(x) such that the
Conversion  Ratio  will  equal  the  actual  rate at which  Infinop  Shares  are
converted  into  Vianet  Shares in the Merger  after  giving  effect to the full
dollar amount of such reduction.
<PAGE>
     (8) STOCK OPTIONS. As of the Effective Time, (1) each outstanding option to
purchase  Infinop Shares listed on Section 4(b) of the  DISCLOSURE  SCHEDULE (AN
"INFINOP STOCK OPTION") SHALL BE CONVERTED INTO AN OPTION (AN "ADJUSTED OPTION")
to purchase the number of Vianet  Shares  equal to the number of Infinop  Shares
subject to such Infinop Stock Option  immediately  prior to the  Effective  Time
multiplied  by the  Conversion  Ratio  (rounded to the nearest  whole  number of
Vianet  Shares),  at an exercise price per share equal to the exercise price for
each such Infinop Share subject to such option divided by the Conversion  Ratio,
and all  references  in each SUCH OPTION TO INFINOP  SHALL BE DEEMED TO REFER TO
VIANET, WHERE APPROPRIATE;  PROVIDED,  HOWEVER, that the adjustments provided in
this clause with respect to any options which are "incentive  stock options" (as
defined in Section 422 of the Code) or which are described in Section 423 of the
Code, shall be affected in a manner  consistent with the requirements of Section
424(a) of the Code, and (2) Vianet shall assume the obligations of Infinop under
the Infinop  Stock  Options and the Infinop 1998 Stock Option Plan (the "INFINOP
STOCK  OPTION  PLAN")  and  stock  option  agreements  between  Infinop  and the
individuals  listed on Section 4(b)(b) of the Disclosure  SCHEDULE (THE "INFINOP
STOCK  OPTION  AGREEMENTS").  For  purposes of this  Section  2(d)  (viii),  the
Conversion  Ratio  shall be  adjusted if  Adjustment  Escrow  Shares (as defined
below)  are  delivered  to  Vianet  as a result  of a  reduction  in the  Merger
Consideration  pursuant to Section  2(d)(x) such that the Conversion  Ratio will
equal the actual rate at which Infinop  Shares are converted  into Vianet Shares
in the Merger after giving effect to the full dollar  amount of such  reduction.
The other terms of each Adjusted  Option,  and the Infinop Stock Option Plan and
Infinop Stock Option Agreements shall continue to apply in accordance with their
terms.  The date of grant of each Adjusted Option shall be the date on which the
corresponding  Infinop Stock Option was granted.  Vianet agrees that the Infinop
Stock  Option Plan shall be  amended,  to the extent  necessary,  to reflect the
transactions contemplated by this Agreement,  including, but not limited, to the
conversion  of Infinop  Shares  held or to be awarded  or paid  pursuant  to the
Infinop  Stock Option Plan and the Infinop Stock Option  Agreements  into Vianet
Shares  on a  basis  consistent  with  the  transactions  contemplated  by  this
Agreement.  Vianet shall (x) reserve for  issuance  the number of Vianet  Shares
that will become  subject to the Infinop Stock Option Plan and the Infinop Stock
Option Agreements referred to in this clause and (y) issue or cause to be issued
the  appropriate  number of Vianet  Shares  pursuant to the Infinop Stock Option
Plan and the Infinop Stock Option  Agreements upon the exercise or maturation of
rights existing thereunder at the Effective Time.

     (9) OTHER  EFFECTS OF THE  MERGER.  The Merger  shall have the  effects set
forth in the Delaware  General  Corporation Law. Without limiting the generality
of  the  foregoing,  and  subject  thereto,  at  the  Effective  Time,  all  the
properties,  rights, privileges, powers and franchises of Infinop and Labs shall
vest in the  Surviving  Corporation,  and all debts,  liabilities  and duties of
Infinop and Labs shall become the debts, liabilities and duties of the Surviving
Corporation.


<PAGE>
     (10) POST CLOSING ADJUSTMENT. Infinop and the Principal Stockholders shall,
within five (5) days after execution and delivery of this Agreement,  deliver to
Vianet unaudited consolidated and consolidating balance sheets and statements of
income as of and for the MONTH  ENDED  JUNE 30,  1999  (THE  "JUNE 30  FINANCIAL
STATEMENTS") for Infinop and its  Subsidiaries  prepared in accordance with GAAP
on a consistent basis, which June 30 Financial Statements will present fairly in
all material respects the financial condition of Infinop and its Subsidiaries as
of such date and the results of operations of Infinop and its  Subsidiaries  for
such  periods and will be  consistent  with the books and records of Infinop and
its  Subsidiaries.  The  June 30  Financial  Statements  will  not  include  any
Liabilities  incurred  after the date of the Most  Recent  Financial  Statements
outside the Ordinary Course of Business.  Vianet shall,  within ninety (90) days
after the Closing,  deliver to the  Principal  Stockholders  a balance  sheet of
Infinop  as of the  Closing  Date  AUDITED  BY EDWARD  ISAACS & CO.,  INC.  (THE
"AUDITED  BALANCE  SHEET").  If the Net  Worth of  Infinop  as set  forth on the
Audited  Balance Sheet is less than the Net Worth of Infinop as set forth on the
June 30 Balance Sheet (the difference  between the Net Worth as set forth on the
Audited  Balance  Sheet and the Net  Worth as set  forth on the June 30  Balance
Sheet to be referred to hereafter  as the  "DEFICIT")  THE MERGER  CONSIDERATION
SHALL BE REDUCED BY THE AMOUNT OF THE  DEFICIT.  FOR  PURPOSES  OF THIS  SECTION
2(D)(X), "NET WORTH" shall mean assets, less liabilities  (including Convertible
Debentures),   determined  in  accordance  with  generally  accepted  accounting
principles.  The  Principal  Stockholders  shall  have  thirty  (30) days  after
delivery 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 not delivered to Vianet  within thirty (30) days after  delivery of
the Audited Balance Sheet,  the Principal  Stockholders  shall be deemed to have
accepted  the Audited  Balance  Sheet.  If an 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 PUBLIC ACCOUNTING 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 and  one-half  percent  (1 1/2%) of the Vianet
Shares  (rounded to the  nearest  whole  number of Vianet  Shares) to which each
Infinop Stockholder (other than Dissenting Shares),  would otherwise be entitled
shall be deposited  into escrow with the Escrow  Agent  pursuant to the terms of
the Escrow AGREEMENT (THE  "ADJUSTMENT  ESCROW  SHARES").  In addition,  one and
one-half  percent  (1  1/2%)  of the  Vianet  Shares  to which  each  holder  of
Convertible  Debentures  would otherwise be entitled upon  conversion  after the
Closing and one and one-half percent (1 1/2%) of the Vianet Shares to which each
holder of Adjusted  Options would  otherwise be entitled upon exercise after the
Closing shall be deposited with the Escrow Agent in accordance with the terms of
the Escrow  Agreement,  if the  issuance of such Vianet  Shares  occurs prior to
final  determination of the Deficit.  For purposes of this Section 2(d)(x),  the
value of each Vianet  Share  shall be deemed to be $7.00.  If there is a Deficit
based upon the Audited Balance Sheet, agreement of the parties, or determination
of the  Accountants,  within  thirty  (30) days after  delivery  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 Adjustment  Escrow Shares to the
Exchange Agent with  instructions  to distribute a number of Vianet Shares equal
in value to the  Deficit  times  the  Escrow  Ratio,  but not in  excess  of the
Adjustment Escrow Shares,  to Vianet and to distribute the remaining  ADJUSTMENT
ESCROW SHARES PRO RATA TO THE INFINOP  STOCKHOLDERS.  THE "ESCROW  RATIO"  shall
mean (A) all issued and outstanding  Infinop Shares at the Closing Date, divided
by (B) all issued and  outstanding  Infinop Shares at the Closing Date, plus all
Infinop  Shares  into which  Convertible  Debentures  as of Closing  Date can be
converted,  plus all Infinop  Shares for which  Infinop  Stock Options as of the
Closing Date can be  exercised.  In no event shall  fractional  Vianet Shares be
distributed,  and in lieu thereof a cash payment  shall be made.  If there is no
Deficit,  within thirty (30) days after  delivery of the Audited  Balance Sheet,
agreement of the parties or determination  of the  Accountants,  as the case may
be,  the  Escrow  Agent  shall  be   instructed  by  Vianet  and  the  Principal
Stockholders to deliver the Adjustment  Escrow Shares to the Exchange Agent with
instructions to distribute the Adjustment  Escrow Shares pro rata to the Infinop
Stockholders.  Recovery  by  Vianet  for the  Deficit  shall be  limited  to the
Adjustment  Escrow Shares and adjustment of the Conversion  Ratio as provided by
Sections 2(d)(vii) and 2(d)(viii).

     (5) PROCEDURE FOR PAYMENT.

     (1)  Immediately  after the Effective  Time, (A) Vianet will, on behalf of,
and for the  benefit of Labs,  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  THAT NUMBER OF VIANET SHARES EQUAL
TO THE PRODUCT OF (1) THE  CONVERSION  RATIO TIMES (2) the number of outstanding
Infinop Shares (other than any Dissenting  Shares) and (B) Vianet will cause the
Exchange Agent to mail a letter of transmittal  (with  instructions for its use)
in form and  substance  reasonably  satisfactory  to the parties  hereto to each
record  holder  of  outstanding   Infinop  Shares  for  the  holder  to  use  in
surrendering  the  certificates  which  represented his or its Infinop Shares in
exchange for a  certificate  representing  the number of Vianet  Shares to which
each of he or it is entitled.  Notwithstanding  anything herein to the contrary,
ten percent (10%) of the Vianet Shares to which the Principal Stockholders would
otherwise be entitled  shall be deposited  INTO ESCROW (THE  "ESCROWED  SHARES")
WITH  CITIBANK,  N.A.,  AS ESCROW AGENT (THE "ESCROW  AGENT") for a period of 24
months following the CLOSING PURSUANT TO THE TERMS OF AN ESCROW AGREEMENT IN THE
FORM  ANNEXED  HERETO  AS  EXHIBIT B (THE  "ESCROW  AGREEMENT")  to  secure  the
     indemnification  obligations  of the  Principal  Stockholders  pursuant  to
Section 9.

     (2) 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  Infinop  Shares until the holder  surrenders for exchange his or
its certificates which represented  Infinop 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 INVESTMENTS;  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  Infinop 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  Infinop  Shares be entitled to any  interest or earnings on the
dividend or distribution pending receipt.

     (3) 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
Infinop  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.


<PAGE>
     (4) Vianet shall pay all charges and expenses of the Exchange Agent and the
charges and expenses of the Escrow  Agent shall be shared  equally by Vianet and
the Principal Stockholders.

     (6) CLOSING OF TRANSFER RECORDS. After the close of business on the Closing
Date,  transfers of Infinop Shares outstanding prior to the Effective Time shall
not be made on the stock transfer books of the Surviving Corporation.

     (7) REGISTRATION  OF, AND  RESTRICTIONS ON, VIANET SHARES.  At the Closing,
Vianet will enter into a Registration Rights Agreement (THE "REGISTRATION RIGHTS
AGREEMENT")  in the form  annexed  hereto as  Exhibit M for the  benefit  of the
Infinop Stockholders,  the holders of the Convertible Debentures and the holders
of the Infinop  Options  covering  registration  under the Securities Act of the
Vianet Shares issued and issuable in exchange for the Infinop Shares,  including
Vianet  Shares  issuable  upon  conversion  of the  Convertible  Debentures  and
exercise of the Infinop Stock Options, and Vianet Shares issuable as part of the
Additional  Payments.  Except as otherwise  provided  below,  the Vianet  Shares
issued and issuable in exchange  for the Infinop  Shares shall be subject to the
following  restrictions  (with such restrictions  applying ratably to the Vianet
Shares issued to each Infinop Stockholder):

     (1) No Vianet  Shares may be traded prior to the six (6) month  anniversary
of the Closing Date;

     (2) 25% of the Vianet Shares shall be freely tradeable six (6) months after
the Closing Date;

     (3) 25% of the Vianet Shares shall be freely  tradeable  twelve (12) months
after the Closing Date; and

     (4) the  remaining  50% of the  Vianet  Shares  shall be  freely  tradeable
twenty-four (24) months after the Closing Date.

     NOTWITHSTANDING  THE  FOREGOING,  IF THE  HOLDERS  OF  THE  8%  CONVERTIBLE
DEBENTURES DUE ON AUGUST 17, 1999 (THE "1999 CONVERTIBLE  DEBENTURES")  exercise
their conversion right and vote their Infinop Shares in favor of the Merger, the
Vianet Shares received by the former holders of the 1999 Convertible  Debentures
shall be subject to the  following  restrictions:  (1) 50% of such Vianet Shares
shall be freely  tradeable  six (6) months after the Closing  Date;  and (2) the
remaining 50% of such Vianet Shares shall be freely tradeable twelve (12) months
after the Closing Date.


<PAGE>
     (8) DISSENTING  SHARES.  Notwithstanding  anything in this Agreement to the
contrary,  Dissenting  Shares shall not be converted into or be exchangeable for
the right to receive the Merger Consideration,  but, instead, the holder thereof
shall be entitled to RECEIVE SUCH CONSIDERATION AS SHALL BE DETERMINED  PURSUANT
TO SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW; PROVIDED,  HOWEVER, that
if such holder shall have failed to perfect or shall have effectively  withdrawn
or lost its rights to dissent under the Delaware  General  Corporation Law, each
of such  holder's  Dissenting  Shares  shall  thereupon  be  deemed to have been
converted into and to have become  exchangeable for the right to receive,  as of
the Effective Time, the Merger  Consideration  (without any interest thereon) in
accordance  with  Section  2(d)(v) and such holder shall  forfeit its  appraisal
rights provided by Section 262 of the Delaware General  Corporation Law. Infinop
shall give Vianet and Labs notice of all such Dissenting Shares and Vianet shall
have the right to participate in all  negotiations  and proceedings with respect
to any demands for payment by the holder of any Dissenting Shares. Infinop shall
not, except with the prior written consent of Vianet,  voluntarily make or agree
to make any  payment  with  respect  to, or settle or offer to settle,  any such
demands for payment. At and as of the Effective Time, the Surviving  Corporation
shall  assume and be  responsible  for the  satisfaction  and  discharge  of all
appraisal  rights to which  holders of Dissenting  Shares may be entitled  under
Section 262 of the Delaware General Corporation Law.

     (9) 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 AUGUST __, 1999 BY AND AMONG VIANET
                  TECHNOLOGIES,  INC., VIANET LABS, INC., INFINOP HOLDINGS, INC.
                  ("INFINOP") AND CERTAIN SHAREHOLDERS OF INFINOP 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 any  certificate  representing
Vianet  Shares not then  subject to the  restrictions  contained in Section 2(g)
from time to time upon written request made to Vianet.

     2A. ADDITIONAL  PAYMENT. As part of the Merger  Consideration,  the Infinop
Stockholders  (other  than any  holders of  Dissenting  Shares),  the holders of
Convertible  Debentures not converted  prior to the Closing Date and the holders
of Adjusted OPTIONS NOT EXERCISED PRIOR TO THE CLOSING DATE  (COLLECTIVELY,  THE
"ADDITIONAL  PAYMENT PAYEES") shall be entitled to receive  ADDITIONAL  PAYMENTS
(THE "ADDITIONAL PAYMENTs") as set forth below:

     (a) The Additional  Payments shall be based on royalties  actually received
by the  Surviving  Corporation  FOLLOWING  THE  CLOSING  UNDER  THE TERMS OF THE
FOLLOWING TWO CONTRACTS (THE "CONTRACTS"):

          (I) THE CONTRACT  DATED JUNE 25TH,  1998 between  Infinop Op, Inc. and
     Video  Stream  International  (now DOING  BUSINESS  AS  "TERAGLOBAL")  (THE
     "TERAGLOBAL CONTRACT"); and


<PAGE>
          (II) THE CONTRACT  DATED OCTOBER 15TH,  1998 between  Infinop Op, Inc.
     and Transwire, Inc. (now doing BUSINESS AS "PRISM") (THE "PRISM CONTRACT").

     (B) THE ADDITIONAL PAYMENTS SHALL BE BASED UPON ROYALTIES (THE "ROYALTIES")
received by the Surviving  CORPORATION  UNDER THE CONTRACTS FOR A PERIOD OF FOUR
(4) YEARS FROM THE DATE OF THE CLOSING (THE "ADDITIONAL  PAYMENT PERIOD").  Each
one (1) year period  commencing  on the Closing Date or the  anniversary  of the
Closing Date shall be referred to in this Section 2A as A "CONTRACT YEAR".

     (c) The Additional Payments payable by Vianet shall be an amount determined
as follows:

          (i) No Additional  Payment shall be required with respect to the first
     $4 million of Royalties  received  during the Additional  Payment Period by
     the Surviving Corporation.

          (ii) When the Surviving  Corporation has received cumulative Royalties
     of $4 million from the Contracts,

Vianet shall be required to pay to the  Additional  Payment Payees as Additional
Payments the following  amount of Royalties earned from the Contracts during the
Additional Payment Period:

          (A) An amount  equal to 50% of Royalties  received  under the terms of
     the Teraglobal Contract.

          (B) An amount  equal to 40% of Royalties  received  under the terms of
     the Prism Contract.


<PAGE>
     (d) The Additional Payments shall be made within thirty (30) days after the
end of each Contract Year for which an Additional Payment is due. All Additional
Payments shall be made in Vianet Shares, unless the Principal Stockholders shall
elect on behalf of all Additional  Payment Payees,  to receive in cash, in whole
or in part, any Additional Payments (which election shall be made by delivery to
Vianet of  written  notice  thereof  at least 10 days prior to the date on which
such  Additional  Payment is required to be made);  provided that, the Principal
Stockholders  shall not have the right to elect to receive payment of Additional
Payments  exceeding $3.2 million in cash. The aggregate  amount of Vianet Shares
to be distributed in respect of the Additional Payments payable in Vianet Shares
shall be calculated  by dividing the dollar  amount  payable in Vianet Shares by
the  average  closing  price of  Vianet  Shares  for the five (5)  trading  days
immediately  preceding  the end of the  Contract  Year for which the  Additional
Payment is payable,  in whole or part, in Vianet Shares. The Additional Payments
shall be paid or allocated pro rata to the Additional  Payment Payees. No holder
of  Convertible  Debentures  or Adjusted  Options  shall be paid any  Additional
Payment until he, she or it has converted to Vianet Shares or exercised his, her
or its option to purchase Vianet Shares.  The Additional  Payments to holders of
Convertible  Debentures  who have not converted and holders of Adjusted  Options
who have not exercised  shall be held in reserve by Vianet until such holder has
converted or  exercised,  as the case may be. If such holder does not convert or
exercise  prior to expiration of his, her or its right to do so, the  Additional
Payments held in reserve shall be distributed  pro rata to the other  Additional
Payment Payees. The Vianet Shares issued in respect of Additional Payments shall
be subject to the  restrictions  set forth in Section 2(g) above,  to the extent
applicable.

     (e) Vianet will  exercise  best efforts to collect all  royalties due under
the terms of the  Contracts,  provided  that the payments will become due to the
Additional  Payment Payees only on Royalties  actually received by the Surviving
Corporation,  except that payments will be due to the Additional  Payment Payees
for Royalties  accrued during the Additional  Payment Period but received by the
Surviving  Corporation  after the termination of the Additional  Payment Period.
After the Closing,  the  Surviving  Corporation  will not amend the Contracts to
reduce the amount of  Royalties  without  the written  consent of the  Principal
Stockholders.

     (f) No payments will be due to the Additional  Payment  Payees  relating to
engineering design or development or consulting fees paid by Teraglobal or Prism
to the Surviving  Corporation  during the Additional  Payment Period,  nor shall
such payments count towards the $4 million amount identified in paragraph (c)(i)
above.

     (g) During the  Additional  Payment  Period,  and for  twelve  (12)  months
thereafter, Vianet will:

          (i) Maintain accurate accounting records of all Royalties accruing and
     received under the Contracts.

          (ii) Within 60 days of the end of each calendar quarter:

          (A)  issue  a  report  to  the  Additional  Payment  Payees  detailing
     royalties accrued and received; and

          (B) remit to the  Additional  Payment Payees the amounts due under the
     provisions of this section.

     (h) Once during each calendar year, the Additional Payment Payees, upon the
approval  or  direction  of  the  Principal   Stockholders  or  otherwise  by  a
majority-in-interest  of the Additional Payment Payees,  shall have the right to
appoint an independent  auditor to review the books and records of the Surviving
Corporation  with regard to the  Additional  Payments due for the previous year,
subject to the following provisions:

          (i) The Additional Payment Payees shall give sixty (60) days notice of
     their intent to conduct an audit.


<PAGE>
          (ii) In the event that the audit  indicates that the amount of Royalty
     payments  reported  by  the  Surviving  Corporation  as  being  due  to the
     Additional  Payment  Payees  under-reported  by 5% or less the  amount  the
     Additional Payment Payees auditors calculate as being due, or over-reported
     the amount the Additional  Payment Payees auditors  calculate as being due,
     the cost of the audit  will be paid by the  Additional  Payment  Payees pro
     rata in accordance  with their  respective  interests.  If  under-reported,
     Vianet will pay to the  Additional  Payment Payees the amount not reported.
     If the Principal  Stockholders pay for the costs of any such audit,  Vianet
     shall, upon the written request of the Principal  Stockholders,  pay to the
     Principal  Stockholders  out  of any  future  Additional  Payments  payable
     hereunder the pro rata portion of the costs of any such audit  allocable to

     payments  reported  by  the  Surviving  Corporation  as  being  due  to the
     Additional  Payment  Payees  under-reported  by more than 5% the amount the
     Additional Payment Payees auditors calculate as being due, the cost of the

     Payees  auditors,  the two auditing  firms shall jointly  appoint a third,
     independent  firm of auditors of national  reputation,  whose  analysis and
     opinion shall be binding.

     (i) Within thirty (30) days after the Closing,  the Principal  Stockholders
will provide to Vianet a list of the Additional  Payment Payees,  the percentage
of the Additional  Payments to which each is entitled and the addresses to which
their payments are to be mailed.

successor, by contract, or otherwise.

     (6) The unpaid Taxes of Infinop and its  Subsidiaries  did not, as of April
30,  1999,  exceed the reserve for Tax  Liability  (rather  than any reserve for

          administration  or  investment  of the  assets  of any  such  Employee
          Benefit Plan. No action, suit,  proceeding,  hearing, or investigation

          any  such  Employee  Benefit  Plan  (other  than  routine  claims  for
          benefits)  is pending  or, to the  Knowledge  of any of the  Principal
          Stockholders,  threatened.  None of the Principal Stockholders has any

taken together,  or the ability of Vianet to perform its obligations  under this
Agreement, the Escrow Agreement or the Registration Rights Agreement. The offer,
sale and  issuance  of the  Vianet  Shares  in  connection  with the  Merger  as

connection  with ownership or alleged  ownership of shares of stock or any other
equity interest in, or any right to share in profits of, or proceeds of sale of,
Computer and INFORMATION SCIENCE, INC. (A "CIS CLAIM").

     (3) INDEMNIFICATION BY VIANET. Vianet agrees to indemnify and hold harmless
the Infinop  Stockholders from and against any and all Adverse Consequences that
the Infinop Stockholders may suffer resulting from, arising out of, relating to,
in the nature of, or caused by:

     (1) any inaccuracy in any of the  representations  and warranties of Vianet
or Labs set forth in this Agreement; or

     (2) any failure of Vianet or Labs to comply with any of their  obligations,
covenants or agreements contained in this Agreement.

     (4) MATTERS INVOLVING THIRD PARTIES.

     (1) If any third party shall notify either a Vianet  Indemnified  Person or
the Infinop  Stockholders,  as the case may be (in EITHER CASE, AN  "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.

     (2) 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  Third  Party  Claim
involves only money  damages and does not seek an injunction or other  equitable
relief,  (B)  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 (C) the Indemnifying
Party conducts the defense of the Third Party Claim actively and diligently. (1)


<PAGE>
     (3) So long as the  Indemnifying  Party is  conducting  the  defense of the
Third Party Claim in accordance with Section 9(d)(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 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).

     (4) In the event any of the  conditions  in  Section  9(d)(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.

indemnification   obligations  under  this  Section  9,  unless  and  until  the
cumulative amount of all Adverse Consequences incurred by the Vianet Group under
this  Section 9 exceeds  $200,000,  in which  event the  Vianet  Group  shall be
entitled to recover from the Principal  Stockholders  pursuant to this Section 9
the  amount of such  Adverse  Consequences  in excess  of  $200,000  and (b) the
liability  of the  Principal  Stockholders  for any  claim  for  indemnification
hereunder shall be limited to, and satisfied exclusively from, the Vianet Shares
on deposit  with the  Escrow  Agent  pursuant  to the  Escrow  Agreement  and no
Principal  Stockholder  shall have any liability for any deficiency with respect
to any such claim. The limitations set forth in the foregoing sentence shall not
apply to any  Adverse  Consequences  arising out of a CIS Claim or any breach of
the  representations  and  warranties  in Section  4(b) or Section  4(f) of this
Agreement.

     (7) INSURANCE PROCEEDS.  The amount of any Adverse  Consequences  otherwise
recoverable  under this Section 9 by any  Indemnified  Party shall be reduced by
any amounts recovered by the Indemnified Party under insurance  policies (net of
any  costs  incurred  in  connection  with the  collection  thereof)  (it  being
understood  that an  Indemnified  Party  shall use its  commercially  reasonable
efforts to timely pursue all reasonable remedies against applicable insurers).

     (8) EXCLUSIVE REMEDY.  Each of Vianet and Labs acknowledges and agrees that
it will not assert,  except  pursuant to and as permitted by this Section 9, any

Infinop  or any of its  Subsidiaries  for  any  inaccuracies,  misstatements  or
omissions with respect to information furnished to Vianet and Labs in connection
with the transactions  contemplated  hereby, it being agreed and understood that
indemnification  under this Section 9 shall be the sole and exclusive remedy for
any such inaccuracies, misstatements or omissions.

     (9) EFFECT OF KNOWLEDGE. Notwithstanding anything to the contrary contained
in this Agreement,  except with respect to a breach of the  representations  and
warranties set forth in Sections 4(a), 4(b), 4(f), 4(m) and 4(cc) (as it relates
to  Sections  4(a),  4(b),  4(f)  and  4(m)),  and a CIS  Claim,  no  claim  for
indemnification  may be asserted by any member of the Vianet  Group  against any
Principal  Stockholder  under this  Section 9 in  respect of any fact,  event or
circumstance giving rise to such claim that was discovered by or known to Vianet
or Labs on or before the Closing,  provided  that,  the  Principal  Stockholders
shall have the burden of proving discovery or knowledge by Vianet or Labs.

jurisdiction  of the state or federal courts located in Delaware,  in connection
with any suit,  action or other  proceeding  arising  out of or relating to this

assert, by way of motion, as a defense, or otherwise in any such suit, action or

Agreement or the subject matter hereof may not be enforced by such courts.

favoring  or  disfavoring  any Party by virtue of the  authorship  of any of the

foreign  statute  or law  shall  be  deemed  also  to  refer  to all  rules  and
regulations promulgated  thereunder,  unless the context otherwise requires. The

<PAGE>
     (1) INFORMAL  RESOLUTION.  The parties agree that before  initiation of any
legal or  arbitration  proceeding  with respect to any issue  arising out of the
transactions  contemplated  by this Agreement,  they shall use their  respective
representatives  to attempt to resolve in good faith all  disputes  between  the
parties. The parties agree that they will cause their respective representatives
to meet in person at a mutually agreeable location,  to attempt in good faith to
resolve  such dispute  within  fifteen  business  days of  notification  of such
dispute.  In the event that the  representatives  are  unable to resolve  such a
dispute, the aggrieved party must refer the dispute to mediation under paragraph

parties, the dispute shall be referred to non-binding  mediation.  The mediation
shall occur within 40 days of the meeting of the parties.  Mediation  fees shall
be split equally among the parties.  The mediator shall be selected by agreement
of the parties or, in the event of no agreement, shall be designated by Judicial
Arbitration and Mediation Services ("JAMS").  The mediation shall be attended by
the parties' representatives and, if desired, the parties' attorneys.

     (3)  ARBITRATION.  In the  event a dispute  is not  resolved  by  mediation
pursuant to  paragraph  (ii),  and the parties  thereafter  mutually  agree,  in
writing, to proceed to binding arbitration,  the aggrieved party shall refer the
dispute  to  binding  arbitration.  The  arbitration  shall be  governed  by the
procedures  set forth below.  The  arbitrator  shall give written  notice to the
parties of the  arbitrator's  determination,  and judgment  upon the same may be
entered by any court of competent jurisdiction.

     (4)  SELECTION  OF  ARBITRATOR.  Within 30 days of referral of a dispute to
arbitration,  a single  arbitrator  will be selected by agreement of the parties
or, in the event of no agreement,  shall be  designated  by JAMS.  Unless agreed
otherwise  by  the  parties,  the  arbitrator  shall  be a  retired  judge  with
arbitration experience.

     (5)  DISCOVERY.  The  parties  agree  to  submit  discovery  plans  to  the
arbitrator  within15  days  following the date that the  arbitrator  accepts his
appointment  to this matter.  The  discovery  plan will  describe all  discovery
contemplated.  The arbitrator will schedule a meeting of counsel to occur within
15 days of his receipt of the discovery plans, at which time the arbitrator will
issue a written order  scheduling dates for all depositions and completion dates
for all additional discovery. The written discovery plan may only be modified by
a written order from the arbitrator. The parties may request, in their discovery
plans,  and the  arbitrator  shall be  empowered to impose,  limitations  on the
nature and quantity of discovery to be conducted.

     (6)  PROCEDURE.  The  arbitration  hearing shall take place in  Wilmington,
Delaware within 90 days of the arbitrator's  acceptance of his appointment.  The
hearing is not to exceed two (2) days. Introduction of evidence and testimony at
the hearing will be subject to the Federal Rules of Civil Procedure.  Each party
is entitled to be heard,  to present  material  evidence and  testimony,  and to
cross-examine witnesses appearing at the hearing.

     (7)  LIMITATION  ON DAMAGES.  The  arbitrator  may not award  exemplary  or
punitive damages.
