(the "Vendor")

Dear Sirs:

The purpose of this letter is to set out the agreement  between  Sierra  Systems
Group Inc. (the  "Purchaser") and the Vendor with respect to the purchase by the
Purchaser and sale by the Vendor of certain business contacts of the Vendor.

1.       REPRESENTATIONS  OF THE VENDOR.  The Vendor  represents and warrants to
the Purchaser that:

         (a)      part of the Vendor's  business is the  development of internal
         and external web sites for clients,  exclusive of integration into such
         of internal enterprise systems ("Web Site Development Services");

         (b)      the clients of the Vendor listed on Schedule A (the "Clients")
         have contracted with the Vendor for Web Site Development Services,  all
         of which are  performed on a time and materials  basis,  except for two
         which are on a retainer basis; and

         (c)      all of the contracts between the Vendor and the Clients are in
         good standing.

2.       AGREEMENT   OF   PURCHASE   AND  SALE.   Relying   upon  the   Vendor's
representations  and  warranties  provided in Section 1 and subject to the terms
and  conditions  hereof,  the Purchaser  offers to pay the Vendor a referral fee
(the "Fee") for each Client that agrees to terminate its  relationship  with the
Vendor with respect to Web Site Development Services and to engage the Purchaser
on terms satisfactory to it to provide Web Site Development Services.

3.       FEES. The Fee to be paid by the Purchaser to the Vendor with respect to
each Client who agrees to have its Web Site  Development  Services  performed by
the Purchaser will be as follows:

<PAGE>

         (a)      15% of the gross revenue billed and collected by the Purchaser
         in respect of Web Site Development  Services provided to the Client for
         the  period  of  three  months   extending  from  the  earlier  of  the
         commencement of the Purchaser  providing Web Site Development  Services
         to the  Client  and March 1, 2000 and 10% of gross  revenue  billed and
         collected for Web Site  Development  Services  provided during the next
         four-month period;

         (b)      the Fee will be calculated and paid monthly, within 30 days of
         the end of each month  based upon gross  revenue  collected  during the
         month;

         (c)      each  payment of the Fee will be  accompanied  by an unaudited
         statement indicating the calculation of the Fee in reasonable detail (a
         "Monthly Statement");

         (d)      the  Vendor  will have 15 days from the time of  receipt  of a
         Monthly  Statement  to  question  the  accuracy  thereof in writing and
         failing  such  objection  the  Monthly  Statement  will be deemed to be
         correct and unimpeachable thereafter;

         (e)      if the Monthly  Statement is questioned by the Vendor,  and if
         such questions cannot be resolved between the Vendor and the Purchaser,
         the Vendor will have the Monthly  Statement  reviewed by its  auditors,
         PricewaterhouseCoopers,  who will be requested to provide their opinion
         on the  calculation of the Fee for the month in question,  such opinion
         to be final and determinative of the Fee payable during the month; and

         (f)      the Fee payable by the Purchaser will be calculated based upon
         the actual gross  revenue  collected  from a Client and the  percentage
         payable   will  be  based  upon  the  period   during  which  the  bill
         representing such gross revenue was rendered,  notwithstanding the time
         when a bill rendered to a Client is actually paid.

4.       AGREEMENT BY VENDOR TO SOLICIT CLIENTS. Forthwith upon the execution of
this  Agreement,  the  Vendor  will  contact  the  Clients  for the  purpose  of
soliciting  their consent to the  termination of their agreement with the Vendor
to provide Web Site Development  Services and to have such services  provided by
the Purchaser on terms which are satisfactory to the Client and the Purchaser.

5.       AGREEMENTS  OF  PURCHASER.  The  Purchaser  hereby  agrees  to use  its
reasonable efforts to:

         (a)      reach agreements with the Clients on terms satisfactory to the
         Purchaser  pursuant  to  which  the  Purchaser  will  provide  Web Site
         Development Services to the Clients;

         (b)      to carry out Web Site  Development  Services  for the  Clients
         upon such agreed upon terms; and

         (c)      to  invoice  the  Clients  on a  timely  basis  for  Web  Site
         Development Services and to collect such.

6.       MUTUAL  AGREEMENT.  The Vendor and the Purchaser agree to work together
from the date hereof for the purpose of transitioning Clients from the Vendor to
the Purchaser.

                                      -2-
<PAGE>

7.       INDEMNIFICATION  OF PURCHASER.  The Vendor agrees to indemnify and save
the Purchaser harmless with respect to all claims and causes of action and costs
(including  lawyers' fees) which may arise due to Web Site Development  Services
provided  to the  Clients  prior to the Client  agreeing  to have such  services
provided by the Purchaser.

8.       NONSOLICITATION OF EMPLOYEES. For the period extending from the date of
acceptance  hereof by the Vendor to September 30, 2000,  both parties  undertake
not to solicit for or  initiate  discussions  to,  hire or  contract  any of the
employees  or  individual  partners  of the  other  party  nor to,  directly  or
indirectly, entice any of such employees or individual partners to terminate his
or her employment  with the other party.  Breach of this clause will entitle the
aggrieved  party, as its only recourse,  to claim from the breaching  party, and
the breaching party will pay to the aggrieved  party upon demand,  as liquidated
damages and not as a penalty,  an amount equal to the  compensation  paid to the
hired employee or individual  partner during the six months prior to being hired
by the  breaching  party.  The  provisions  of this Section 8 will not prevent a
party from  discussing  employment or from hiring such an employee or individual
partner  where the  party is first  approached  by the  employee  or  individual
partner  in  circumstances  where the  party is not in breach of the  provisions
hereof.

9.       NOTICE. Any notice or other  communication  required or permitted to be
given  hereunder  or for the  purposes  hereof  will be  sufficiently  given  if
delivered  to the  party to whom it is  given  or sent by  means  of  electronic

            C. Credit Facility Fee. Section 3.4(d) of the Credit Agreement is
hereby deleted in its entirety and replaced with the following:

            "(d) Credit Facility Fee. Borrower agrees to pay Agent for the
account of all Lenders an annual credit facility fee of Seventy-five Thousand
Dollars ($75,000) (the "Credit Facility Fee). The Credit Facility Fee shall be

purchase of its stock from third-party shareholders up to Five Million Two
Hundred Fifty Thousand Dollars ($5,250,000) in the Third Amendment dated

Borrower shall not breach any financial covenant set forth in Section 9.3.1 of
the Credit Agreement as a result of Borrower's payment of the purchase price for

conditions, each as acceptable to Agent, in its sole discretion (the date on
which all such terms and conditions are satisfied being the "Amendment Effective

      (b) such other and further documents and agreements as Agent may determine
in connection with any of the foregoing.

      4. Miscellaneous. Except to the extent specifically amended herein, all
terms and conditions of the Credit Agreement and the other Loan Documents are
hereby ratified and reaffirmed and shall remain in full force and effect.
Capitalized terms used but not defined herein shall have the meanings given them
in the Credit Agreement. Borrower waives notice of Agent's and each Lender's
acceptance of this Amendment. Agent and each Lender reserves all of their
respective rights and remedies under the Credit Agreement and other Loan
Documents.

      IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of
the date first written above.
