                             RIGHTS OF FIRST REFUSAL
 4.1     Delivery of Sale Notice
         In the event that any Holdings  shareholder (the "Offeror")  desires to
transfer all but not less than all the Holdings shares owned by him, the Offeror
shall  first  deliver  a notice  in  writing  (a  "Sale  Notice")  to the  other
shareholders  (the  "Offerees")  whereby  the  Offeror  offers  to sell all such
Holdings shares (the "Offered  Shares") to the Offerees for the respective price
per Holdings share,  payable in cash on closing,  set out in the Sale Notice and
on and subject to the other terms and  conditions  therein set out. The Offerees
shall have the right,  exercisable by giving notice (an "Acceptance  Notice") to
the Offeror within fifteen Business Days after its receipt of a Sale Notice (the
"Acceptance  Period")  to  purchase  all,  but not less than all, of the Offered
Shares  offered to it in  accordance  with the Sale Terms.  In the event that no
Acceptance Notice is received from an Offeree within the Acceptance  Period, the
offer to such Offerees shall be deemed to have been refused.
 4.2     Sales Notices Irrevocable
         The delivery by an Offeror of a Sales Notice shall be irrevocable  and,
upon delivery by an Offeree of an Acceptance  Notice, the Offeror shall be bound
to sell, and the Offeree shall be bound to purchase, the relevant Offered Shares
in accordance with the Sale Terms.
 4.3     Sales to Third Parties
         If,  following the  completion  of the procedure  stipulated in section
4.1, the Offered Shares remain  unaccepted by the Offeree,  the Offeror may sell
the Offered  Shares to any person (a "Third Party") at a price not less than the
price set forth in the Sale Notice and on terms no more  favourable to the Third
Party than the Sale Terms. If no such sale is completed by the Offeror within 90
days  following  the  expiration  of the 15 Business  Day period  referred to in
section 4.1,  the Offeror  shall be required,  before  transferring  any Holding
shares,  again to offer such  shares in the manner  provided  in section 4.1 and
such process shall be repeated so often as any party to this  Agreement  desires
to transfer any Holdings shares.
 4.4     Tag-Along Rights
         In the event that an Offeror  proposes to sell the Offered  Shares to a
Third Party pursuant to section 4.3, the Offeror shall, within 60 days following
the expiry of the 15  Business  Day Period  referred  to in  section  4.1,  give
written notice (the  "Tag-Along  Notice") of the identity of the Third Party and
the price and other material terms of the transaction  which shall be consistent
with the  requirements  of section 4.3, to the Offeree (a  "Declining  Offeree")
that elected not to exercise  its right to purchase  such  Offered  Shares.  The
Declining  Offeree may, not later than five  Business  Days after receipt of the
Tag-Along Notice, deliver the Offeror a notice in writing invoking the provision
of this  section 4.4 (a  "Tag-Along  Demand").  The  delivery  by the  Declining
Offeree of a Tag-Along  Demand  shall be  irrevocable  and shall bind  Declining
Offeree to sell all but not less than all of the Holdings  shares (the  "Tagging
Shares") owned by the Declining  Offeree,  in accordance  with the provisions of
this section 4.4. If the Declining  Offeree delivers a Tag-Along  Demand,  then,
before  completing  any sale, the Offeror shall cause the Third Party to deliver
to the Declining Offeree a bona fide offer in writing (the "Tag-Along Offer") to
purchase from such Declining  Offeree the Tagging  Shares.  The Tag-Along  Offer
will be  binding  upon the Third  Party and shall  contain  only such  terms and
conditions as are identical to those upon which the Offeror  proposes to sell to
the Third Party the Offered  Share  pursuant to section 4.3,  provided  that the
offer price per Holdings share, which shall be specified in the Tag Along Offer,
shall be the same consideration as, or the cash equivalent of; the consideration
per Holding  share at which the Offeror  proposes to sell to the Third Party the
Offered  Shares  pursuant to section  4.3.  The closing  date and other  closing
arrangements for the purchase and sale transaction between the Declining Offeree
and the Third Party shall be specified in the  Tag-Along  Offer and shall be the
same,  mutatis  mutandis,  as those  specified  between  the Third Party and the
Offeror.
 4.5     Drag-Along Rights
         In the event that an Offeror  proposes to sell the Offered  Shares to a
Third  Party  pursuant  to section  4.3,  the  Offeror  may,  by written  notice
delivered  within 60 days  following  the expiry of the 15  Business  Day period
referred  to  in  section  4.1  to  the  Declining  Offeree,  accompanied  by an
irrevocable offer (the "Drag-Along Offer") from the Third Party to the Declining
Offeree  to  purchase,  for a  consideration  that is the same  as,  or the cash
equivalent of; the consideration per
Holdings share at which the Offeror  proposes to sell its Holdings  shares owned
by such Declining Offeree (the "Dragged Shares") requiring the Declining Offeree
to sell to the Third Party all such Dragged Shares at the price specified in the
Drag-Along Offer. The delivery by the Offeror of an irrevocable Drag-Along Offer
shall bind the Declining  Offeree to sell the Dragged Shares.  The date on which
the sale is to close  and the other  closing  arrangements  (which  shall be the
same,  mutatis  mutandis,  as those for the  purchase and sale between the Third
Party and the Offeror) shall be as specified in the Drag-Along Offer.  Except as
specifically  provided for above,  the Drag-Along  Offer shall contain only such
terms and  conditions,  if any, as are identical to those  pursuant to whiche th
Offeror proposes to sell to the Third Party the offered Shares.
