                      Amendment to Stock Option Agreements

This Amendment to Stock Option Agreements is entered into as of _________ __,
2001, and amends certain Stock Option Agreements dated as of May 10, 2000 and
April 4, 2001 (the "Original Agreements") by and between Oplink Communications,
Inc. (the "Company") and Ian Jenks (the "Optionee") whereby the Optionee was
granted an option to purchase an aggregate of 425,000 shares of the Company's
common stock (the "Options").

Whereas, the Board of Directors of the Company has determined that it would be
in the best interests of the Company and its stockholders to modify the terms of
the Options to provide for acceleration of the vesting and make certain other
changes described herein.

Now, Therefore, for good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged by the parties, the parties hereby agree as
follows:

1.   Effective as of November 7, 2001, the Options granted to Optionee pursuant
     to the Original Agreements shall vest in full and become fully exercisable.

2.   Notwithstanding anything contrary in Section 9(b) of the Company's 1998
     Stock Option Plan or Section 6(h) of the Company's 2000 Equity Incentive
     Plan, the Optionee may exercise the Options until November 7, 2006. If
     Optionee does not exercise his Options before November 7, 2006, the Options
     shall terminate.

3.   Except as amended by this Amendment, the Original Agreements shall remain
     in full force and effect.

4.   This Amendment shall be governed by and construed in accordance with the
     laws of the State of California without giving effect to the conflicts of
     law principles thereof.

In Witness Whereof, the parties hereto have executed this Amendment as of the
date first above written.

     This  CONSULTING  AGREEMENT  ("Agreement") is entered into this 18th day of
September  2001,  by  and  between  E-REX,  INC.,  a  Nevada  corporation  (the
"Company"),  and  Jonathan  Keane  ("Consultant").

     1.     Engagement  of Consultant.  The Company hereby engages Consultant to
            -------------------------
assist  the  Company  in  marketing  and  sales  services.

     2.     Compensation.  As  total  and complete compensation for his services
            ------------
provided herein, the Company shall issue to Consultant 349,524 shares ("Shares")
of  the  Company's  restricted common stock ("Stock"), par value $.001 per share
valued  at  the  price  of  $.045  per  share  .

     3.     Expenses.  Company  shall  assume  and  shall be responsible for all
            --------
expenses  incurred  by Consultant and shall be responsible for all disbursements
made in Consultant's activities.  Except as otherwise specifically authorized by
the  President of the Company in advance, in writing, Consultant shall not incur
on  behalf  of  Company,  and  Company  shall  not  have,  any liability for any
expenses,  costs,  and  disbursements of Consultant.  Consultant shall indemnify
and  hold  Company  harmless  from  and  against any and all claims, actions, or
liability for any expenses, costs, and disbursements, including attorneys' fees,
of  Consultant  or  its  agents,  servants,  contractors,  or  employees.

     4.     Term  of Agreement.  This Agreement shall commence on the date first
            ------------------
set  forth above and shall continue in full force and effect for a period of one
(1)  year.  Either  party,  at its option, may terminate this Agreement prior to
the  expiration of such one (1)-year period by providing the other party written
notice  of  intent  to  terminate  not  less  than thirty (30) days prior to the
effective  date  of termination.  Notwithstanding the foregoing, the Company may
immediately  terminate  this  Agreement  if  Consultant  materially  breaches an
obligation  hereunder.

     5.     Relationship  of the Parties; Consultant's Limitations of Authority.
            -------------------------------------------------------------------
Except  as  otherwise specifically set forth in this Agreement, Consultant shall
have no authority to represent Company as an agent of Company.  Consultant shall
have  no  authority  to  bind  Company  by  any  contract,  representation,
understanding,  act,  or  deed  concerning  Company.  Except  as  otherwise
specifically  set  forth  herein,  neither  the making of this Agreement nor the
performance  of  any  part  of  the  provisions  hereof  shall  be  construed to
constitute Consultant as an employee, agent or representative of Company for any
purpose,  nor  shall  this  Agreement  be deemed to establish a joint venture or
partnership.  Consultant,  in  all  respects,  shall  be  deemed  an independent
contractor  with  respect  to  the  performance by Consultant of its obligations
hereunder.

     6.     Assignment.  Neither  this  Agreement  nor  any  of  the  duties  or
            ----------
obligations of Consultant herein may be voluntarily, involuntarily, directly, or
indirectly  assigned,  delegated,  or  otherwise  transferred  or  encumbered by
Consultant  without  the  prior,  written  approval  of  the  Company.  Any such
assignment,  delegation,  transfer, or encumbrance without such approval will be
void  and  will  constitute  a "material breach" of this Agreement entitling the
Company  to terminate this Agreement immediately.  A change in voting control of
Consultant  shall  be deemed an assignment of this Agreement.  This Agreement is
fully  assignable  by the Company and shall inure to the benefit of any assignee
or  other  successor.

     7.     Miscellaneous  Provisions.
            -------------------------

          7.1     Entire  Agreement; Binding Effect.  This Agreement constitutes
                  ---------------------------------
the  entire  agreement between the parties with respect to the subject matter of
this Agreement and supersedes any prior agreements or understandings between the
parties.  This  Agreement  shall  be  binding on and inure to the benefit of the
parties  hereto  and  their  respective  successors  and  authorized  assigns.

          7.2.     Modification.  This  Agreement  may be modified only upon the
                   ------------
execution  of  a  written  agreement  signed  by  both  of  the  parties.

          7.3     Waivers.  No  failure  on  the  part of either party hereto to
                  -------
exercise,  and  no  delay  in  exercising, any right, power, or remedy hereunder
shall  operate  as  a waiver thereof nor shall any single or partial exercise of
any  right,  power,  or remedy hereunder preclude any other or further exercises
thereof  or  the  exercise  of  any  other  right,  power,  or  remedy.

          7.4     Governing  Law;  Venue and Jurisdiction.  This Agreement shall
                  ---------------------------------------
be  deemed  to have been entered into in, and for all purposes shall be governed
by,  the laws of the State of Florida, without regard to Florida's choice of law
decisions.  The  parties  agree  that any action brought by either party against
the other in any court, whether federal or state, shall be brought within Orange
County,  Florida,  in the applicable state and federal judicial districts and do
hereby  waive all questions of personal jurisdiction or venue for the purpose or
carrying  out  this  provision.

          7.5     Attorneys'  Fees.  In  the  event  of  a  dispute  under  this
                  ----------------
Agreement,  the  non-prevailing  party  shall  pay all of the prevailing party's
reasonable  attorneys'  fees  and  costs  incurred  in  connection with any such
action,  including  post-judgment  collection  proceedings.

          7.6     Severability.  In  the  event  that  any  provision  of  this
                  ------------
Agreement,  in  whole  or  in  part  (or  the  application of any provision to a
specific  situation),  is  held  to  be  invalid  or  unenforceable by the final
judgment  of  a  court  of  competent  jurisdiction after appeal or the time for
appeal  has expired, such invalidity shall be limited to such specific provision
or portion thereof (or to such situation), and this Agreement shall be construed
and applied in such manner as to minimize such unenforceability.  This Agreement
shall  otherwise  remain  in  full  force  and  effect.

          7.7     Counterparts.  This  Agreement  may  be executed in two (2) or
                  ------------
more  counterparts, each of which shall be deemed an original, but all of which,
taken  together,  shall  constitute  one  and  the  same  instrument.

     In  witness  whereof, the parties hereto have executed this Agreement as of
the  date  and  year  first  above  written.

                                -----------------

     This  Consulting  Services Agreement (the "Agreement") is entered this 24th
day  of  August,  2001  by  and  between

                                TORSTEN PROCHNOW

("Consultant"),  an  International  consultant,  and

                                   E-REX, INC.

("Client"),  a  U.S.  corporation  (ticker  symbol: EREX), with reference to the
following:

                                    RECITALS

   A.   The  Client  desires  to be assured of the services of the Consultant in
order  to  avail  itself  of  the  Consultant's  experience,  skills, knowledge,
abilities  and  background  in  the  fields  of  business development, financial
consulting, and Internet strategy. The Client is therefore willing to engage the
Consultant  upon  the  terms  and  conditions  set  forth  herein.

   B.   The  Consultant agrees to be engaged and retained by the Client upon the
terms  and  conditions  set  forth  herein.

   NOW  THEREFORE,  in  consideration  of  the foregoing, of the mutual promises
herein  set forth and for other good and valuable consideration, the receipt and
sufficiency  of  which  are  hereby  acknowledged, the parties agree as follows:

   1.   ENGAGEMENT.  Client  hereby engages Consultant on a non-exclusive basis,
        -----------
and Consultant hereby accepts the engagement to become a strategic consultant to
the  Client and to render such advice, consultation, information and services to
the  Client  regarding general financial and business matters including, but not
limited  to:

A.  LISTING  SERVICES

major  European  stock  exchange  (e.g.  Frankfurt  Stock  Exchange).

-  Handling  of  the  application  and  of all paperwork on behalf of the client
needed  to  complete  the  listing  process  in  accordance with German and U.S.
securities  and  exchange  rules.

Client  understands  that  Consultant  cannot guarantee that Client's securities
will  be  listed  for  trading  on  any  exchange  because  the decision to list
securities  for  trading  rests  with  the  exchange  itself.

B.  RELATED  PUBLIC  RELATIONS  SERVICES

- Researching, editing and generating a minimum of two guaranteed articles about
EREX in connection with the aforementioned listing and submission of these texts

German and U.S. newspapers and magazines (e.g. "Financial Times Deutschland" and
"Frankfurter  Allgemeine  Zeitung").

-  Editing  and  delivering a comprehensive stock exchange fact sheet in English
before  the  actual  application  will  be  filed.

-  Preparation of comprehensive company press releases about the application for
a  listing  and  about  the  successful  execution  of  the  listing.

        -----
hereof  and  continue  for  two  (2)  months. The Agreement may be extended upon

common  stock  representing an aggregate value of US$15,000 (150,000 shares at a
price  of  US$0.10  per  share) to be delivered to the Consultant in lieu of the
cash  payments  provided  above.  The  Shares  will  be  freely  tradable  upon
registration  with  the  Securities  ands  Exchange Commission on Form S-8, duly
authorized,  validly  issued  and  outstanding, fully paid and nonassessable and
will  not  be  subject  to  any liens or encumbrances. In the event the exchange

partial  refund of $US5, 000.00 cash or 50,000 shares (at consultants choice) as
paid  under  this  agreement.

a  third  party.  When  issued  pursuant to such Warrants, the underlying shares
shall  be  duly  authorized,  validly  issued  and  outstanding,  fully paid and
nonassessable  and  will  not  be  subject  to  any  liens  or  encumbrances.

Consultant  reserves  the  right to renegotiate the number of shares received as
compensation if the price of the Client's shares decreases on any stock exchange
of  more  than  20%  before  completion  of  the  services  described  above.

   4.   EXCLUSIVITY;  PERFORMANCE; CONFIDENTIALITY.   The services of Consultant

at  any  specific  time,  or  in  any specific place or manner, unless otherwise
mutually  agreed.  Payments  to  consultant  hereunder  shall  not be subject to
withholding  taxes  or  other  employment  taxes  as  required  with  respect to
compensation  paid  to  an  employee.

   6.   MISCELLANEOUS.  No  waiver  of  any  of the provisions of this Agreement
        --------------

waiver  shall constitute a continuing waiver.  No waiver shall be binding unless
executed  in  writing  by  the  party  making  the  waiver.  No  supplement,
