CUSIP No. 0585H 10 4                     13D                         Page 4 of 9


The Schedule 13D filed by Ford Motor Company and Ford Global Technologies, Inc.
on April 20, 1998, as amended by Amendment Number 1 to Schedule 13D filed by
Ford Motor Company and Ford Global Technologies, Inc. dated December 10, 2001,
and as amended by Amendment Number 2 to Schedule 13D filed by Ford Motor Company
and Ford Global Technologies, LLC dated January 18, 2005, is amended as
hereinafter provided.

Item 1.           Security and Issuer.

This Schedule 13D relates to the Ballard Common Shares (the "Ballard Common
Shares") of Ballard Power Systems Inc. ("Ballard"), a corporation incorporated
under the Canada Business Corporation Act whose principal executive offices are
located at 4343 North Fraser Way, Burnaby, British Columbia, Canada V5J 5J9.

Item 2.           Identity and Background.

This Schedule 13D is filed jointly by Ford Motor Company, a Delaware corporation
("Ford"), and Ford Global Technologies, LLC, a Delaware limited liability
company ("FGTL"). FGTL is a wholly-owned subsidiary of Ford. Ford's principal
executive offices are located at One American Road, Dearborn, Michigan 48126.
FGTL's principal executive offices are located at One Parklane Blvd., Suite 911,
Parklane Towers East, Dearborn, Michigan 48126.

Ford is a manufacturing company whose principal business is the design,
manufacture, assembly and sale of cars and trucks and related products and
services. FGTL manages certain intellectual property of Ford and Ford's
affiliates. Ford Global Technologies, Inc. ("FGTI"), an entity that managed
certain intellectual property of Ford and Ford's affiliates, merged into FGTL on
March 1, 2003. As a result of the merger effective March 1, 2003, Ballard Common
Shares previously owned by FGTI are now owned by FGTL.

Information concerning the name, business address, principal occupation and
citizenship of each executive officer and director of Ford and FGTL is attached
in Exhibit 1 hereto and incorporated herein by reference.

Neither Ford nor FGTL nor, to the knowledge of Ford or FGTL, any of their
executive officers or directors, have been convicted during the last five years
in a criminal proceeding (excluding traffic violations or similar violations).
Neither Ford nor FGTL, nor to the knowledge of Ford or FGTL, any executive
officer or director of Ford or FGTL, during the last five years, was a party to
a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violations with respect to such laws.


Item 3.           Source and Amount of Funds or Other Consideration.

(a) On April 7, 1998, FGTI acquired an aggregate of 12,237,165 Ballard Common
Shares (after giving effect to a three for one stock split in June, 1998), and,
as a result of the merger described above in Item 2 above, such Ballard Common
Shares are now owned by FGTL.

(b) On November 30, 2001, pursuant to an Acquisition and Plan of Merger
Agreement among, inter alia, Ford, FGTI, DaimlerChrysler AG ("DCX") and Ballard
dated October 2, 2001, Ford acquired a total of 9,917,876 Ballard Common Shares
by private placement from Ballard as follows:




CUSIP No. 0585H 10 4                     13D                         Page 5 of 9


         (i) Ford acquired 919,624 Ballard Common Shares at a price of
CDN$27.185 per Ballard Common Share, for an aggregate purchase price of
CDN$24,999,978.44; and

         (ii) Ford acquired 8,998,252 Ballard Common Shares in consideration for
the merger of Ford's wholly-owned subsidiary, Ford Electric Drive Holdings
Company ("Ford Electric"), with and into a wholly owned subsidiary of Ballard.
Ford Electric held a 62.1% interest in Ecostar Electric Drive Systems LLC and a
21.8% interest in Xcellsis AG.

(c) On January 12, 2005, pursuant to a Call Agreement dated December 31, 2003
(the "Call Agreement") among Ford, DCX, Ballard and DBF Pref Share Holdings
Inc., Ballard issued to Ford, and Ford acquired from Ballard, 2,026,157
additional Ballard Common Shares by way of a private placement for a purchase
price of CDN$25,000,000.

(d) On August 31, 2005, pursuant to an Acquisition Agreement dated June 23, 2005
(the "Acquisition Agreement") among Ford, Ballard and DCX, Ford transferred to
Ballard an aggregate 11,312,498 Ballard Common Shares to Ballard for
cancellation, of which 8,306,606 Ballard Common Shares held by FGTL were
transferred to Ballard in exchange for a 50% interest in Ballard Power Systems
AG ("BPS AG") (formerly Xcellis AG) held by Ballard, and 3,005,892 Ballard
Common Shares held by FGTL were transferred to Ballard in exchange for the
termination of certain obligations of Ford in respect of electric drives for
hybrid vehicles contained in the Third Alliance Agreement entered into by Ford,
Ballard, Ballard Power Corporation and DCX on November 30, 2001.

All of the funds used for Ford's purchase of Ballard Common Shares were derived
from its working capital.


Item 4.           Purpose of Transaction.

Ford initially acquired Ballard Common Shares in order to participate in a
global alliance with Ballard and DCX for the development, marketing and sale of
fuel cell engines and related technology.

On August 31, 2005, pursuant to the Acquisition Agreement and in relation to the
Fourth Alliance Agreement dated August 31, 2005 among Ford, Ballard, DCX and DBF
Pref Share Holdings Inc. (the "Fourth Alliance Agreement"), Ballard and its
subsidiary, Ballard Power Corporation, transferred to Ford and DCX all of the
shares of BPS AG in exchange for Ballard Common Shares (the "Fourth Alliance
Transaction"). As a result of the Fourth Alliance Transaction, Ford acquired a
50% interest in BPS AG in exchange for 8,306,606 Ballard Common Shares owned by
Ford. In addition, DCX acquired a 50% interest in BPS AG in exchange for 693,394
Ballard Common Shares owned by DCX and the termination of the Ford Exchange
Agreement dated October 2, 2001 pursuant to which Ballard was to acquire DCX's
49.9% interest in BPS AG in exchange for the issuance of 7,613,212 Ballard
Common Shares to DCX.

Item 5.           Interest in Securities of the Issuer.

Ford owns the direct legal and beneficial ownership interest and the sole right
to vote and dispose of 11,944,033 Ballard Common Shares. FGTL owns an additional
924,667 Ballard Common Shares. As the parent company of FGTL, Ford is the
indirect beneficial owner of the 924,667 Ballard Common Shares owned by FGTL.
Accordingly, Ford and FGTL have shared dispositive and voting power over the
924,667 Ballard Common Shares held by FGTL. Ford's overall interest in Ballard
amounts to 12,868,700 Ballard Common Shares, representing approximately 11.5% of
the issued and outstanding Ballard Common Shares calculated on the basis of
111,672,446 Ballard Common Shares outstanding as of July 26, 2005.





CUSIP No. 0585H 10 4                     13D                         Page 6 of 9


Item 6.           Contracts, Arrangements, Undertakings or Relationships With 
                  Respect to Securities of the Issuer.


Certain rights and obligations of Ford and DCX with respect to Ballard and
Ballard's Common Shares were amended effective August 31, 2005 in connection
with the completion of the Fourth Alliance Transaction. Details of the
amendments are as follows:

Board of Directors. Since 1998, each of Ford and DCX, through shareholdings in 
the jointly-owned company, DBF Pref Share Holdings Inc. ("DBF"), have been 
entitled to elect a number of directors of Ballard based on its respective 
percentage ownership of Ballard Common Shares, with the number of directors to 
be elected by each of them being rounded up to the next whole number where that 
percentage results in an entitlement to elect more than two-thirds of a director
and being rounded down to the next whole number otherwise.

Under the Fourth Alliance Transaction, Ford's right to elect directors has been
revised in two ways:

o   the number of directors to be appointed by Ford will be:

        o  rounded up to the nearest whole number where Ford's percentage 
           ownership results in an entitlement to elect more than one-half of a 
           director; and

        o  rounded down to the nearest whole number where Ford's percentage 
           ownership results in an entitlement to elect one-half of a director 
           or less; and

o   in circumstances where the percentage ownership of Ford results in it
    being entitled to appoint from 1.3 to 1.51 directors, it will be entitled
    to appoint two directors.

Other than its director appointment rights, Ford, as long as the Class A share
of Ballard held by DBF on behalf of Ford is outstanding, is prohibited from
voting its Common Shares to elect or remove directors or to change the rights or
restrictions attached to the Class A share. Ford may, however, in its
discretion, provide a proxy to vote in favor of the election of directors
nominated by management of Ballard.

Limited Voting Provisions. Prior to the Fourth Alliance Transaction, certain
decisions of Ballard's board of directors could not be undertaken without
approval by a number of directors equal to one director more than a majority of
the directors who were entitled to vote and who did vote on such decision,
including at least one of the directors appointed by Ford or DCX (the "Limited
Voting Provisions"). If any director appointed by Ford or DCX was absent or
abstained or was otherwise prohibited from voting, a simple majority would
suffice, and such majority need not include one of the directors appointed by
Ford or DCX. These Limited Voting Provisions applied so long as Ford and DCX
continued to own in the aggregate at least:

(a)      one-third of the outstanding Common Shares, not including shares
         Ballard issues in connection with an acquisition or investment in a
         third party that is subject to the Limited Voting Provisions (the
         "Threshold Percentage");




CUSIP No. 0585H 10 4                     13D                         Page 7 of 9


(b)      20% of all of Ballard's outstanding shares; and

(c)      all of the Common Shares held by Ford and DCX respectively, after
         giving effect to the Fourth Alliance Transaction (other than 2,954,781
         Common Shares owned by Ford and 3,977,650 Common Shares owned by DCX)
         ("Ballard Base Shares");

and each of Ford and DCX:

(d)      owned a sufficient number of Ballard's Common Shares to entitle each of
         them to elect at least one of Ballard's directors; and

(e)      elected at least one of Ballard's directors when entitled to do so.

Prior to the Fourth Alliance Transaction, if the Limited Voting Provisions
ceased to apply to Ford and DCX collectively, it was possible for the Limited
Voting Provisions to be re-applied if either or both of Ford and DCX acquired at
any subsequent time at least 37.92% of the outstanding Common Shares and then
continued to meet the requirements set out in (a) to (e) above.

There are no material changes to the Limited Voting Provisions (as fully
described in Amendment No. 1) under the Fourth Alliance Transaction. However,
there are three changes with respect to the circumstances in which the Limited
Voting Provisions are applicable:

o   the Threshold Percentage has been lowered from one-third of Ballard's
    outstanding Common Shares to one-quarter of Ballard's outstanding Common
    Shares (subject to being increased back to one-third in limited
    circumstances);

o   if Ford and DCX's aggregate ownership of the Common Shares falls below the
    Threshold Percentage, the Limited Voting Provisions will continue to apply
    during a 60-day cure period, and

        o  if Ford and DCX increase their aggregate ownership of the
           outstanding Common Shares to more than the Threshold Percentage
           within such cure period, the Limited Voting Provisions will
           continue in effect thereafter; or

        o  if Ford and DCX fail to increase their aggregate ownership of the
           outstanding Common Shares to more than the Threshold Percentage
           within the cure period, the Limited Voting Provisions will be
           terminated at the end of the cure period, subject to reinstatement
           if Ford and DCX increase their aggregate ownership of the
           outstanding Common Shares to more than the Threshold Percentage
           within 18 months after the expiry of the cure period; and

o   if the Limited Voting Provisions cease to apply to Ford and DCX
    collectively, it is possible for the Limited Voting Provisions to be
    re-applied to Ford or DCX if either of them, as the case may be, acquires
    at any subsequent time at least 33.75% of the outstanding Common Shares or
    owns all of the other's Ballard Base Shares and then continues to meet the
    requirements set out above.

Equity Participation Rights. The Fourth Alliance Agreement continues to provide
that if Ballard undertakes an equity offering, Ford has the right to purchase
a sufficient number of Common Shares to enable it to maintain its equity 
interest in Ballard at its current level.

Officer Nomination Rights. Each of Ford and DCX continues to have a right to
propose, for consideration by Ballard's board of directors, individuals for the
offices of Chief Executive Officer, Chief Financial Officer, Chief Technology
Officer (or other officer to whom the persons responsible for research and
development report, or other officer to whom the person responsible for
vehicular fuel cell programs report) and Vice-President, Research and
Development (or other officer to whom the persons responsible for intellectual
property report).





CUSIP No. 0585H 10 4                     13D                         Page 8 of 9


Officer Removal Rights. Ford and DCX continue to have joint removal rights over
Ballard's Chief Technology Officer (or other officer to whom the persons
responsible for research and development report, or other officer to whom the
persons responsible for vehicular fuel cell programs report) and Ballard's
Vice-President, Research and Development (or other officer to whom the persons
responsible for intellectual property report).

Articles of Amendment. In order to implement the revised director appointment
rights of each of Ford and DCX and to reflect the changes to the Limited Voting
Provisions, Ballard has amended its Articles, effective August 31, 2005. A copy
of the full text of the Articles of Amendment is attached as Exhibit 4 to this
Amendment No. 3.

Arrangements Between Ford and DCX Respecting the Purchase and Sale of Ballard
Common Shares. Ford and DCX have established procedures, effective August 31, 
2005, for the purchase and sale of Common Shares where permitted to do so 
pursuant to the Fourth Alliance Agreement. The arrangements provide that each 
party will provide notice to the other before purchasing Common Shares; that 
purchases made by both parties at the same time will be made pro rata up to the 
amounts elected or permitted to be purchased by the parties; and that each party
will provide prior notice to the other before selling Common Shares. The 
arrangements do not provide any rights in favor of either party to acquire 
Common Shares held by the other, and do not create any investment, dispositive 
or voting rights in favor of either party with respect to Common Shares held by 
the other party.

A more detailed description of the contractual arrangements forming part of the
Fourth Alliance Transaction with respect to the matters disclosed in Item 4 and
Item 6 of this Amendment No. 3 is attached hereto as Exhibit 3 and is
incorporated herein by reference.

To the knowledge of Ford and FGTL, no executive officer or director of Ford or
FGTL owns any Ballard Common Shares.


Item 7.           Material to be Filed as Exhibits.

specified in such Private Placement Subscription, and DCX will cause such
members of its Group to purchase from Ballard and pay the subscription price
for, an aggregate number of Equity Securities equal to the lesser of

         (a) the maximum number of Equity Securities specified in such Private
         Placement Subscription, and

         (b) the number of Equity Securities that when issued to members of the
         DCX Group would result in the members of the DCX Group owning the same
         proportion of the outstanding Ballard Common Shares calculated on a
         Fully Issued basis, as they would have owned on the date of issuance of
         Equity Securities under this Section 2.11 if the members of the DCX
         Group had purchased the DCX Group Cap (calculated as if Ford delivered
         a Participation Notice for the number of Equity Securities equal to the
         Aggregate Cap) for the Equity Financing pursuant to Section 2.7.

         Subject to Section 2.13, if Ford has purchased Equity Securities
         pursuant to Section 2.8, such number of Equity Securities in this

         B    = The proportion held by the DCX Group of the outstanding Ballard
              Common Shares, calculated on a Fully Issued basis, as it would
              have been if the DCX Group had purchased the DCX Group Cap
              (calculated as if Ford delivered a Participation Notice for the
              number of Equity Securities equal to the Aggregate Cap) for the
              Equity Financing pursuant to Section 2.7, and

         C    = The number of Ballard Common Shares outstanding immediately
              before the issuance of Equity Securities under this Section 2.11,
              calculated as if every Equity Security issued pursuant to the
              Equity Financing that is convertible or exchangeable into or
              otherwise carries the right to acquire Ballard Common Shares had
              been converted, exchanged or exercised as the case may be,


                                      -18-


         otherwise, such number of Equity Securities in this Section 2.11(b) is
calculated, subject to Section 2.13, as follows:

           ((B* D) - E)

               DCX Group immediately before the issuance of Equity Securities
               under this Section 2.11,

         B =   The Aggregate Maximum Percentage,

         C     = The proportion held by the DCX Group of the outstanding Ballard
               Common Shares, calculated on a Fully Issued basis, as it would
               have been if the DCX Group had purchased the DCX Group Cap
               (calculated as if Ford delivered a Participation Notice for the
               number of Equity Securities equal to the Aggregate Cap) for the
               Equity Financing pursuant to Section 2.7,

         D     = The number of Ballard Common Shares outstanding immediately
               before the issuance of Equity Securities under this Section 2.11,
               calculated as if every Equity Security issued pursuant to the
               Equity Financing that is convertible or exchangeable into, or

NUMBER OF EQUITY SECURITIES IN PRIVATE PLACEMENT TO FORD

2.12 Subject to Section 2.13, within 30 days after receipt of a Private
Placement Subscription under Section 2.10, Ballard will, subject to receipt of
all necessary approvals of Governmental Authorities and stock exchanges and to
Ford being a Ballard Base Shareholder at the time that Equity Securities are
issued pursuant to this Section 2.12, issue to the members of the Ford Group
specified in such Private Placement Subscription, and Ford will cause such

         Ford Group would result in the members of the Ford Group owning the
         same proportion of the outstanding Ballard Common Shares, calculated on
         a Fully Issued basis, as they would have owned on the date of issuance
         of Equity Securities under this Section 2.12 if the members of the Ford
         Group had purchased the Ford Group Cap (calculated as if DCX delivered
         a Participation Notice for the number of Equity Securities equal to the
         Aggregate Cap) for the Equity Financing pursuant to Section 2.8.


                                      -19-


         Subject to Section 2.13, if DCX has purchased Equity Securities
         pursuant to Section 2.7, such number of Equity Securities in this
         Section 2.12(b) is calculated as follows:

               (B* C) - A

         B     = The proportion held by the Ford Group of the outstanding
               Ballard Common Shares, calculated on a Fully Issued basis, as it
               would have been if the Ford Group had purchased the Ford Group
               Cap (calculated as if DCX delivered a Participation Notice for
               the number of Equity Securities equal to the Aggregate Cap) for
               the Equity Financing pursuant to Section 2.8, and

         C     = The number of Ballard Common Shares outstanding immediately
               before the issuance of Equity Securities under this Section 2.12,
               calculated as if every Equity Security issued pursuant to the
               Equity Financing that is convertible or exchangeable into, or
               otherwise carries the right to acquire Ballard Common Shares had
               been converted, exchanged or exercised as the case may be,

         otherwise, such number of Equity Securities in this Section 2.12(b) is
calculated, subject to Section 2.13, as follows:

           ((B* D) - E)
         C*(----------) + (C* D) - A
           (   1 - B  )

         where:

               under this Section 2.12.

         C     = The proportion held by the Ford Group of the outstanding
               Ballard Common Shares, calculated on a Fully Issued basis, as it

               the number of Equity Securities equal to the Aggregate Cap) for
               the Equity Financing pursuant to Section 2.8,

         D     = The number of Ballard Common Shares outstanding immediately
               before the issuance of Equity Securities under this Section 2.12,
               calculated as if every Equity Security issued pursuant to the
               Equity Financing that is convertible or exchangeable into, or
               otherwise carries the right to acquire Ballard Common Shares had
               been converted, exchanged or exercised as the case may be,

         E     = The total number of Ballard Common Shares owned by the members

MAXIMUM FOR PRIVATE PLACEMENT

2.13 The number of Equity Securities issued pursuant to Section 2.11 or Section
2.12 will not exceed the number of Equity Securities that would result in the
members of the DCX Group and the Ford Group owning immediately after such
issuance, in the aggregate, the Aggregate Maximum Percentage of the outstanding
Ballard Common Shares, calculated on a Fully Issued basis.

         Such maximum number of Equity Securities is calculated as follows:

           (B* C) - A
           ----------
              1 - B

         where:

         A =   The total number of Ballard Common Shares owned by members
               of the DCX Group and the Ford Group immediately before the
               issuance of Equity Securities under Section 2.11 or Section 2.12,
               calculated as if every Equity Security issued to a member of
               either such Group pursuant to the applicable Equity Financing
               that is convertible or exchangeable into, or otherwise carries
               the right to acquire Ballard Common Shares had been converted,

               before the issuance of Equity Securities under Section 2.11 or
               Section 2.12, calculated as if every Equity Security issued
               pursuant to the applicable Equity Financing that is convertible
               or exchangeable into, or otherwise carries the right to acquire
               Ballard Common Shares had been converted, exchanged or exercised
               as the case may be.

PRICE FOR PRIVATE PLACEMENT SECURITIES

2.14     The price for Equity Securities to be issued pursuant to Section 2.11
or Section 2.12 will be the greater of

         (a) the issue price of the Equity Securities issued pursuant to the
         applicable Equity Financing, and

         (b) the lowest price at which such securities may be issued by Ballard
         pursuant to the written policies of The Toronto Stock Exchange
         applicable to private placements, if Ballard's securities are then
         listed on The Toronto Stock Exchange and, if not so listed, pursuant to
         the written policies on private placements of all then applicable
         securities regulators and stock exchanges.

REGULATORY APPROVALS

2.15 Ballard will use all reasonable efforts to obtain all approvals of stock
exchanges and, to the extent appropriate, Governmental Authorities and the
relevant Ballard Base Shareholder, to the extent appropriate, will use all
reasonable efforts to obtain all approvals of Governmental Authorities,
necessary for the issuance of Equity Securities subscribed for pursuant to
Section 2.7, Section 2.8,


                                      -21-


Section 2.11 or Section 2.12, but if any such stock exchange or Governmental
Authority notifies Ballard or the relevant Ballard Base Shareholder that it will
not grant such an approval in the circumstances

         (a) the relevant Ballard Base Shareholder and each member of its Group
         will be released from its obligation to purchase such Equity Securities
         and will not be considered to have failed to purchase the maximum
         number of Equity Securities in respect of the Equity Financing to which
         they relate, and

         (b) Ballard will be released from its obligation to issue the Equity
         Securities referred to in Section 2.15(a) to that Ballard Base
         Shareholder and the members of its Group.

NO OBLIGATION OF BALLARD TO QUALIFY EQUITY SECURITIES

2.16 Each of DCX and Ford acknowledges that any Equity Securities acquired by
members of its Group pursuant to Section 2.11 or Section 2.12, respectively,
will be subject, in accordance with applicable securities laws and the rules and
policies of applicable stock exchanges, to restrictions on resale and that
Ballard will have no obligation to qualify any Equity Securities so issued by
issuance under applicable securities laws of a prospectus, registration
statement or similar document, provided however, for greater certainty, the
Parties acknowledge that the Ballard Common Shares issued pursuant to the Call
Agreement are not being issued pursuant to Section 2.11 or Section 2.12 and that
this Section 2.16 shall in no way affect Ballard's obligations under or pursuant
to the registration rights agreement among the Parties in respect of the Ballard
Common Shares issued pursuant to the Call Agreement.

NO DISPOSITION OF BALLARD COMMON SHARES DURING PARTICIPATION

2.17 Notwithstanding any other rights granted under this Agreement, once a
Ballard Base Shareholder gives a Participation Notice or a Private Placement
Subscription to Ballard, it will ensure that no member of its Group will sell,
transfer or otherwise dispose of any Ballard Common Shares, except to one or
more other members of its Group, until the earlier of the completion of the
issuance of Equity Securities pursuant to such Participation Notice or Private
Placement Subscription and the 60th day after delivery of the Participation
Notice or Private Placement Subscription, as the case may be.

         (b) by way of a Circular Bid made after November 30, 2005 and on or

         Ford Group would own in the aggregate, at least two-thirds, calculated
         on a Fully Diluted basis, of all outstanding Ballard Common Shares if
         members of both Groups own Ballard Common Shares or, if no member of
         one such Group owns Ballard Common Shares, at least two-thirds,

                           50%, calculated on a Fully Diluted basis, of all
                           outstanding Ballard Common Shares if members of both
                           Groups own Ballard Common Shares or, if no member of
                           one such Group owns Ballard Common Shares, more than
                           50%, calculated on a Fully Diluted basis, of all

                  directors of Ballard elected by DBF Holdings at the direction
                  of DCX and Ford are no longer entitled to exercise the rights
                  pursuant to Section 7.21, Section 7.24 or Section 7.26, as

                  Ballard Common Shares that would entitle DBF Holdings, as the

3.14 RETENTION OF SPECIAL APPROVAL RIGHTS. If the aggregate percentage of all of
the outstanding Common Shares held by members of the DCX Group and the Ford
Group at any time falls below the Threshold Percentage, notwithstanding
ss.3.12(a)(i), the rights set out in ss.3.12 will remain in effect for a period
of 60 days thereafter. If during that 60 day period members of the DCX Group and
the Ford Group

    (a) acquire sufficient Common Shares so that the aggregate proportion of all
    of the outstanding Common Shares held by members of the DCX Group and the
    Ford Group meets or exceeds the Threshold Percentage, the rights set out in

    rights set out in ss.3.12 will thereafter come into effect if, within 18

    proportion of all of the outstanding Common Shares held by members of the
    DCX Group and the Ford Group meets or exceeds the Threshold Percentage, at
    which time this ss.3.14 will again be applicable.

For the purpose of determining whether the members of the DCX Group and the Ford
Group hold a number of Common Shares equal to the Threshold Percentage, the
number of Common Shares issued in consideration of a material investment in, or
acquisition of, a Person other than a wholly-owned Subsidiary of the Corporation
that was required to be approved, and was approved, under ss.3.12 or ss.3.15,

4.14 RETENTION OF SPECIAL APPROVAL RIGHTS. If the aggregate percentage of all of
the outstanding Common Shares held by members of the DCX Group and the Ford
Group at any time falls below the Threshold Percentage, notwithstanding
ss.4.12(a)(i), the rights set out in ss.4.12 will remain in effect for a period
of 60 days thereafter. If during that 60 day period members of the DCX Group and
the Ford Group

    (a) acquire sufficient Common Shares so that the aggregate proportion of all
    of the outstanding Common Shares held by members of the DCX Group and the
    Ford Group meets or exceeds the Threshold Percentage, the rights set out in

    Threshold Percentage, at which time this ss.4.14 will again be applicable,
    or

    (b) do not acquire sufficient Common Shares so that the aggregate proportion
    of all of the outstanding Common Shares held by members of the DCX Group and

    rights set out in ss.4.12 will thereafter come into effect if, within 18
    months following the expiry of such 60 day period, members of the DCX Group

    proportion of all of the outstanding Common Shares held by members of the
    DCX Group and the Ford Group meets or exceeds the Threshold Percentage, at
    which time this ss.4.14 will again be applicable.

For the purpose of determining whether the members of the DCX Group and the Ford
Group hold a number of Common Shares equal to the Threshold Percentage, the
number of Common Shares issued in consideration of a material investment in, or
acquisition of, a Person other than a wholly-owned Subsidiary of the Corporation

    the board of directors of the Corporation at which a matter specified in any
    of ss.4.12(c) to ss.4.12(o), inclusive, is considered, other than solely as
    a result of the occurrence of circumstances preventing such participation
    that are entirely beyond the control or remedy of such director (including,
    but not limited to, a medical emergency or accident of such director or an
    immediate family member of such director),


                                      -28-
