                      same bases and principles as are referred to in Clause 6.2
                      and (unless both the Vendors and the Purchaser shall
                      otherwise direct in writing) determine the form and
                      content of the Completion Accounts and the Net Asset

         6.6.2        the decision of such firm of chartered accountants as to
                      the matter in dispute and their determination (if any) as
                      to the form and content of the Completion Accounts and the
                      Net Asset Statement shall, in the absence of


                                       11
   14


                      manifest error, be final and binding on the Parties and
                      such chartered accountants shall be deemed to act as
                      experts and not as arbitrators.

6.7      The costs of the Auditors in respect of the preparation and
         determination of the Completion Accounts shall be borne by the Vendors

                  such excess and the Purchaser shall not be concerned to see to

8.       POST-COMPLETION OBLIGATIONS

         8.1      Each of the Vendors undertakes with the Purchaser (for itself
                  and as trustee for the Company) that, except with the consent
                  in writing of the Purchaser and subject to the provisions of
                  Clause 8.3:

                  or debentures of any company listed on a recognised stock
                  exchange). Notwithstanding the foregoing, any of the Vendors
                  may be employed by a company which engages in the business of
                  web hosting, provided such Vendor does not directly
                  participate in, supervise, manage or control the web hosting

                  Company or in the habit of


                                       12

                  away from the Company any person who at the date hereof is or
                  at the date of or within the year preceding such employment,
                  solicitation, enticement or attempt shall have been an
                  officer, manager, consultant or employee of the Company
                  whether or not such person would commit a breach of contract
                  by reason of leaving such employment;

         8.1.4    he will not at any time hereafter make use of or disclose or
                  divulge to any person (other than to officers, employees, or
                  professional advisers of the Company whose province it is to
                  know the same) any information (other than any information
                  properly available to the public or disclosed or divulged
                  pursuant to an order of a court of competent jurisdiction)
                  relating to the Company, the identity of its customers and
                  suppliers, its products, finance, contractual arrangements,
                  business or methods of business and shall use his best
                  endeavours to prevent the publication or disclosure of any
                  such information, except in his capacity as a continuing
                  director and employee of the Company, as may be appropriate;

         8.1.5    if, in connection with the business or affairs of the Company,
                  he shall have obtained trade secrets or other confidential
                  information belonging to any third party under an agreement
                  purporting to bind the Company which contained restrictions on
                  disclosure he will not without the previous written consent of
                  the board of directors of the Purchaser at any time infringe
                  or take any action which would or might result in an
                  infringement of such restrictions;

         8.1.6    he will not at any time hereafter in relation to any trade,
                  business or company use a name or trade mark including the
                  word or symbol Helix or its Chinese equivalent or any word or
                  symbol confusingly similar thereto in such a way as to be
                  capable of or likely to be confused with the name or any trade
                  mark of the Company and shall use his best endeavours to
                  procure that no such name or trade mark shall be used by any
                  person, firm or company with which he is connected.

8.2      Each Vendor shall procure that all companies and businesses directly or
         indirectly owned or controlled by him shall be bound by and observe the
         provisions of Clause 8.1 to Clause 8.4 as if they were parties
         covenanting with the Purchaser in the same terms.

8.3      While the restrictions contained in Clause 8.1 to Clause 8.4 are
         considered by the parties to be reasonable in all the circumstances, it
         is recognised that restrictions of the nature in question may fail for
         technical reasons and accordingly it is hereby agreed and declared that
         if any of such restrictions shall be adjudged to be void as


                                       13
   16


         going beyond what is reasonable in all the circumstances for the
         protection of the interests of the Purchaser but would be valid if part
         of the wording thereof were deleted or the periods thereof reduced or
         the range of activities or area dealt with thereby reduced in scope the
         said restriction shall apply with such modifications as may be
         necessary to make it valid and effective.

8.4      The restrictions contained in sub-Clauses 8.1 and 8.2 above shall be
         without prejudice to performance by and shall not limit the
         restrictions on Choi, Leung Chi under the terms of his employment
         agreement entered into pursuant to this Agreement.

8.5      The Purchaser agrees to provide the Company with HK$800,000 in cash as
         working capital, in accordance with the Company's reasonable expansion
         needs, but in no event later than 31 March 2000.

         1999 entered into between the Company and Dell Computer Asia Ltd. with
         financing provided by Newcourt Credit Hong Kong Limited (the "Lessor"),
         the Vendors shall indemnify the Company and the Purchaser against any
         and all losses, expenses, costs or damage suffered or incurred by the
         Company that are directly caused by any failure to obtain the Lessor's
         consent to the sale and purchase of the Sale Shares by the Vendors to
         the Purchaser.

8.7      The Vendors shall indemnify the Company and the Purchaser against any
         and all losses, expenses, costs or damage suffered or incurred by the
         Company that are directly caused by any unauthorised or infringing use
         of any computer programs or software by the Company.

8.8      The Vendors shall indemnify the Company and the Purchaser against any
         and all losses, expenses, costs or damage suffered or incurred by the

         between the Company and Ms. Hsu Chi Liang and Yip Lina (the "First
         Landlord"), the Vendors shall indemnify the Company and the Purchaser

9.       WARRANTIES

9.1      Each of the Vendors jointly and severally represents, warrants and
         undertakes to and with the Purchaser that each of the statements set
         out in Schedule 7 is now true and accurate.

9.2      The Warranties (other than Warranties 1, 2, 3, 4, 5.1 and 15 in respect
         of which no qualification is accepted) are given subject to matters
         fully, fairly and specifically disclosed in the Disclosure Letter but
         no other information relating to the Company of which the Purchaser has
         knowledge (actual or constructive) and no investigation by or on behalf
         of the Purchaser shall prejudice any claim made by the Purchaser under
         the Warranties or operate to reduce any amount recoverable, and
         liability in respect thereof shall not be confined to breaches
         discovered before Completion. No letter, document or other
         communication shall be deemed to constitute a disclosure for the
         purposes of this Agreement unless the same is accepted as such by the
         Purchaser and is expressly referred to in the Disclosure Letter.

9.3      The Vendors acknowledge that the Purchaser has entered into this
         Agreement in reliance upon the Warranties and has been induced by them
         to enter into this Agreement.

9.4      Without restricting the rights of the Purchaser or otherwise affecting
         the ability of the Purchaser to claim damages on any other basis
         available to it, in the event that any of the Warranties is broken or
         (as the case may be) proves to be untrue or misleading, the Vendors
         shall, on demand, pay to the Purchaser or, at the Purchaser's
         direction, the Company subject to Clauses 9.11 to 9.14:

         9.4.1    the amount necessary to put the Company into the position
                  which would have existed if the Warranties had not been broken
                  or (as the case may be) had been true and not misleading; and

         9.4.2    all costs and expenses incurred by the Purchaser and the
                  Company in connection with or as a result of such breach and
                  any costs (including legal costs on a solicitor and own client
                  basis), expenses or other liabilities which any of them may
                  incur either before or after the commencement of any action in
                  connection with (i) any legal proceedings in which the
                  Purchaser claims that any of the Warranties has been broken or
                  is untrue or misleading and in which judgment is given for the
                  Purchaser or (ii) the enforcement of any settlement of, or
                  judgment in respect of, such claim (the amounts, costs and
                  expenses described in Clause 9.4.1 and this Clause 9.4.2,
                  collectively are referred to herein as "Adverse
                  Consequences").

9.5      Each of the Warranties shall be separate and independent and, save as
         expressly provided to the contrary, shall not be limited by reference
         to or inference from any other Warranty or any other term of this
         Agreement, nor by anything in the Disclosure Letter which is not
         expressly referenced to the Warranty concerned.

9.6      Where any statement in the Warranties or any confirmation or
         certificate given by any of the Vendors hereunder or pursuant hereto is
         qualified by the expression "so far as


                                       15
   18


         the Vendors are aware" or "to the best of the Vendors' knowledge and
         belief" or any similar expression, that statement shall be deemed to
         include an additional statement that it has been made after due and
         careful enquiry.

9.7      Each of the Vendors hereby agrees with the Purchaser (for itself and as
         trustee for the Company) to waive any rights which he may have in
         respect of any misrepresentation or inaccuracy in, or omission from,
         any information or advice supplied or given by the Company or its
         officers, employees or advisers in connection with the giving of the
         Warranties and the preparation of the Disclosure Letter.

9.8      The Vendors shall give to the Purchaser and its solicitors and
         accountants both before and after Completion all such information and
         documentation relating to the Company as the Purchaser shall reasonably
         require to enable it to satisfy itself as to the accuracy and due
         observance of the Warranties.

9.9      The benefit of the Warranties may be assigned in whole or in part and
         without restriction by the person for the time being entitled thereto.

9.10     If any sum payable by the Vendors under this Clause 9 shall be subject
         to Tax (whether by way of deduction or withholding or direct assessment
         of the person entitled thereto) such payment shall be increased by such
         an amount as shall ensure that after deduction, withholding or payment
         of such Tax the recipient shall have received a net amount equal to the
         payment otherwise required hereby to be made.

9.11     The Purchaser shall notify the Vendors in writing within a reasonable
         period of time after becoming aware of, and shall provide to the
         Vendors at such time all material information and documentation in its
         possession reasonably necessary to support and verify, any Adverse
         Consequences that the Purchaser shall have determined have given rise
         to, or could reasonably be expected to give rise to, a claim under this
         Clause 9.

9.12     If any third party shall notify the Purchaser of any matter which may
         give rise to a claim under this Clause 9, then the Purchaser shall
         promptly notify the Vendors thereof in writing. The Vendors shall have
         the right to defend the Company and/or Purchaser against the third
         party claim with counsel of its choice satisfactory to the Purchaser,
         provided the Vendors conduct the defense of such third party claim
         actively and diligently.

9.13     The Vendors shall not have any liability for indemnification under this
         Clause 9 for breaches of the Warranties until the aggregate amount of
         all Adverse Consequences in connection with or as a result of such
         breach exceeds HK$50,000.

9.14     The liabilities of the Vendors under the Warranties shall:

         (a)      cease after a period of two (2) years commencing on the
                  Completion Date hereof except in respect of matters which have
                  been the subject of a written claim made before such date by
                  the Purchaser or the Purchaser's Solicitors to any of the
                  Vendors or the Vendors' Lawyers; and


                                       16
   19


         (b)      in relation to the year 2000 or Malfunction (as defined in
                  paragraph 9 of Schedule 5 herein) Warranties in paragraphs
                  5.19, 8.5 and 9.8 of Schedule 5 herein, be limited to a
                  maximum aggregate amount of HK$4,500,000;

         PROVIDED ALWAYS that if in any case the relevant claim or claims has
         arisen by reason of:

         9.14.1         fraud or wilful concealment or dishonesty or deliberate
                        non disclosure on the part of any of the Vendors or on
                        the part of any officer or representatives of the
                        Company prior to the date of this Agreement; or

         9.14.2         the Company not having good title to any asset
                        (including any shares or stock of any company) of which
                        it is now warranted to be the owner; or

         9.14.3         any of the Vendors or any signatory on their respective
                        behalfs being claimed not to have had legal authority or
                        capacity to enter into the Agreement or any agreement
                        ancillary thereto;

         then in any such case none of the limitations whether as to amount or
         time set forth in this Clause 9.14 shall apply.


10.      RETIREMENT SCHEME

         The Vendors represent and warrant that there is no Occupational
         Retirement Scheme operated in respect of the Directors and employees of
         the Company.

         Each of the Parties undertakes that it will not (save as required by
         law or by any securities exchange or any supervisory or regulatory body
         to whose rules any of the Parties is subject) make any announcement in
         connection with this Agreement unless the other Parties shall have
         given their respective consents to such announcement (which consents
         may not be unreasonably withheld or delayed and may be given either
         generally or in a specific case or cases and may be subject to
         conditions).


12.      CONFIDENTIALITY OF INFORMATION RECEIVED BY THE VENDORS

12.1     The Vendors undertake with the Purchaser that they shall treat as
         strictly confidential all information received or obtained by them or

         body pursuant to rules to which the relevant Vendor is subject or from
         making any disclosure to any professional adviser for the purposes of

         observed in relation to, the use or disclosure by such professional
         adviser of the information provided to him) nor shall the restrictions

         previous agreements or arrangements between them relating to the

         authorised representatives of the Parties.

         effect notwithstanding Completion (except insofar as they set out
         obligations which have been fully performed at Completion).

14.4     If any provision or part of a provision of this Agreement shall be, or
         be found by any authority or court of competent jurisdiction to be,
         invalid or unenforceable, such invalidity or unenforceability shall not
         affect the other provisions or parts of such provisions of this
         Agreement, all of which shall remain in full force and effect.

                                       18
   21


         and no exercise or failure to exercise such a right of rescission shall
         constitute a waiver by the Purchaser of any such other right or remedy.

14.7     The Purchaser may release or compromise the liability of any of the
         Vendors hereunder or grant to any Vendor time or other indulgence
         without affecting the liability of any other Vendor hereunder.

         delay or forbearance in exercising, any right or remedy in respect of
         any provision of this Agreement shall operate as a waiver of such right
         or remedy.

14.9     Upon and after Completion the Vendors shall do and execute or procure
         to be done and executed all such further acts, deeds, documents and
         things as may be necessary to give effect to the terms of this
         Agreement and to place control of the Company in the hands of the
         Purchaser and pending the doing of such acts, deeds, documents and
         things the Vendors shall as from Completion hold the legal estate in
         the Sale Shares in trust for the Purchaser.

14.10    This Agreement may be executed in one or more counterparts, and by the
         Parties on separate counterparts, but shall not be effective until each
         party has executed at least one counterpart and each such counterpart
         shall constitute an original of this Agreement but all the counterparts
         shall together constitute one and the same instrument.
