DEBENTURE AGREEMENT  

        THIS DEBENTURE AGREEMENT (as amended or supplemented from time to time, the "Agreement"), dated as of August
    , 2002, is made by and between PARADIGM GEOTECHNOLOGY B.V., a private company with limited liability (besloten vennootschap met beperkte
aansprakelijkheid) organized under Netherlands law (the "Company"), and PARADIGM GEOTECHNOLOGY HOLDINGS B.V., a private company
with limited liability (besloten vennootschap met beperkte aansprakelijkheid) organized under Netherlands law ("Holder"). 

        WHEREAS,
on August 8, 2002, Holder acquired 3,700 ordinary shares, par value €5.00 per share, of the Company, which shares, following a reduction in the par value
of ordinary shares of the Company from €5.00 per share to €0.01 per share, are currently represented by 1,850,000 Ordinary Shares; 

        WHEREAS,
Holder desires to contribute (the "Contribution") all of its assets and liabilities to the Company, except for the 1,850,000
Ordinary Shares referred to above; 

        WHEREAS,
Holder and the Company desired that the Holder would receive Ordinary Shares and convertible preference shares in the share capital of the Company in exchange for the
Contribution; 

        WHEREAS,
Holder and the Company have considered that the Netherlands company law imposes certain undesirable restraints in connection with convertible preference shares; 

        WHEREAS,
Holder and the Company desire to achieve, as nearly as is practicable, the economic effect of issuing Ordinary Shares and convertible preference shares of the Company in
exchange for the Contribution, and in particular desire the full Contribution to increase the economic potential of the Company; 

        WHEREAS,
as a result of the foregoing, Holder and the Company desire for the Company to issue in exchange for the above Contribution (i) 5,916,990 Ordinary Shares and
(ii) Debentures having an aggregate principal amount of US $51,059,000.00; and 

        WHEREAS,
Holder and the Company desire to treat the Debentures, which are debt obligations for purposes of the Netherlands company law, as equity for Netherlands tax law purposes. 

        NOW,
THEREFORE, in consideration of the foregoing premises and of the mutual covenants and agreements herein contained, each party hereto agrees as follows for the benefit of the other
and for the equal and ratable benefit of the holders of the Debentures (as de-fined below). 

 
 

1.     AUTHORIZATION OF DEBENTURES.         The Company has authorized the issue and sale of US
$                  US $51,059,000.00 (FIFTY ONE MILLION FIFTY-NINE THOUSAND UNITED STATES DOLLARS)
aggregate principal amount of its Convertible Subordinated Debentures (the "Debentures," such term to include any such debentures issued in substitution
therefor pursuant to Section 14 of this Agreement), which are stapled to 51,059 Ordinary Shares (the "Stapled Shares"). The Debentures shall be
substantially in the form set out in Exhibit 1 hereto, with such changes therefrom, if any, as may be approved by the Holder and the Company.
Certain capitalized terms used in this Agreement are defined in Schedule A hereto; references to a "Schedule" or an "Exhibit" are, unless
otherwise specified, to a Schedule or an Exhibit attached to this Agreement. 

 
 

2.     ISSUE OF DEBENTURES.         Subject to the terms and conditions of this Agreement, the Company hereby is-sues and sells to
Holder, and Holder hereby purchases from the Company,
in partial consideration for the Contribution, an aggregate of US $51,059,000.00 in principal amount of Debentures at 100% of the principal amount thereof. 

 

 
 

3.     REPRESENTATIONS AND WARRANTIES OF THE COMPANY.         The Company represents and warrants to Holder that: 

	3.1
	ORGANIZATION;
POWER AND AUTHORITY. 

        The
Company is a Dutch company duly organized, validly existing and in good standing under Dutch law. The Company has the corporate power and authority to execute and deliver this
Agreement and the Debentures and to perform its obligations hereunder and thereunder. 

	3.2
	AUTHORIZATION,
ETC. 

        This
Agreement and the Debentures have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement and the Debentures constitute legal, valid
and binding obligations of the Company enforceable against the Company in accordance with its terms. The Ordinary Shares issuable upon conversion of the Debentures have been duly authorized and
reserved for issuance and upon issuance, upon conversion of the Debentures, will be validly issued, fully paid and nonassessable. 

	3.3
	PRIVATE
OFFERING BY THE COMPANY. 

        Neither
the Company nor anyone acting on its behalf has offered the Debentures or any similar securities for sale to, or solicited any offer to buy any of the same from, or
other-wise approached or negotiated in respect thereof with, any person other than Holder, which has been offered the Debentures at a private sale for investment. Neither the Company nor
anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Debentures to the registration requirements of Section 5 of the Securities Act. 

 
 

4.     REPRESENTATIONS OF THE HOLDER.         

	4.1
	ORGANIZATION;
POWER AND AUTHORITY. 

        Holder
is a Dutch company duly organized, validly existing and in good standing under Dutch law. Holder has the corporate power and authority to execute and deliver this Agreement and to
perform its obligations hereunder. 

	4.2
	AUTHORIZATION,
ETC. 

        This
Agreement has been duly authorized by all necessary corporate action on the part of Holder, and this Agreement constitutes a legal, valid and binding obligation of Holder
enforceable against Holder in accordance with its terms. 

	4.3
	PURCHASE
FOR INVESTMENT. 

        Holder
represents that it is purchasing the Debentures for its own account and not with a view to the public distribution thereof, provided that the disposition of its property shall at
all times be within its control. Holder understands that the Debentures have not been registered under the Securities Act and may be resold only if registered pursuant to the provisions of the
Securities Act or if an exemption from registration is available, except under circumstances where neither such registration nor such an exemption is required by law, and that the Company is not
required to register the Debentures. 

 
 

5.     TERM.         Debentures shall have a perpetual term, without any stated maturity date. 

2

 

 
 

6.     PAYMENT OF INTEREST.         Holders of Debentures shall be entitled to receive interest payments in an amount per Debenture
equal to that sum calculated as if the Debentures participated
equally and ratably with the holders of Ordinary Shares in all dividends and distributions paid (whether in the form of cash, securities or
otherwise) on Ordinary Shares determined as if immediately prior to each record date for payment of such dividend or distribution in respect of Ordinary Shares, all Debentures then outstanding were
converted into Ordinary Shares in the manner provided under Section 8, and at the Conversion Price in effect on such record date. Accordingly, each holder of Debentures shall receive on the
payment date of such dividend or distribution on Ordinary Shares an amount per Debenture of cash, securities or other property so distributed as such holder would have received had such holder
converted, at the Conversion Price in effect on the record date for the payment of such dividend or distribution, all of the principal amount of such Debenture into Ordinary Shares immediately prior
to the record date for the payment of such dividend or distribution. 

 
 

7.     REDEMPTION OF THE DEBENTURES.         

	7.1
	REDEMPTION;
REDEMPTION PRICE. 

        At
any time or from time to time, subject to any holder's right to first convert Debentures into Ordinary Shares, the Company may redeem (a
"Redemption") the Debentures in whole or in part at a redemption price per Debenture equal to the Redemption Price as of the Redemption Date, together
with any accrued and unpaid interest payable in accordance with Section 6 in respect of dividends or distributions on Ordinary Shares having a payment date on or prior to the Redemption Date.
For purposes of this Agreement, the "Redemption Price" means, as of any date, an amount per Debenture equal to the greater of (i) the sum of
(x) the principal amount outstanding under such Debenture and (y) the Premium as of such date, and (ii) the product of multiplying (x) the total number of Ordinary Shares
that would be issuable upon con-version of such Debenture immediately prior to such date, at the Conversion Price in effect on such date, by (y) the Fair Market Value per Ordinary
Share determined as of such date. For purposes of this Agreement, the "Premium" means, as of any date, an amount per Debenture equal to the amount of
interest, computed on the basis of a 360-day year of twelve 30-day months, that would have accrued at an annual rate of 5.0% (compounded quarterly) on the principal amount of
such Debenture during the period commencing on the date hereof through such date. 

        In
the case of any Debenture which is redeemed in part only, upon such Redemption the Company shall execute and deliver to the holder thereof, at the expense of the Company, a new
Debenture or Debentures in aggregate principal amount equal to the portion of the principal amount of such Debenture that has not been redeemed. In the case of any Debenture which is redeemed, in
whole or in part, after any record date for the payment of any dividend or distribution in respect of Ordinary Shares and on or prior to the date fixed for payment of such dividend or distribution,
the interest due in accordance with Section 6 in respect of such dividend or distribution shall be payable, without duplication, to the holders on such record date notwithstanding such
Redemption, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Debenture is registered at the close of business on such record date. 

	7.2
	ELECTION
TO REDEEM; NOTICE TO HOLDERS. 

        The
Company shall give each holder of Debentures written notice of a Redemption not less than two Business Days prior to the date fixed for such Redemption (the
"Redemption Date"), specifying the Redemption Date and the Redemption Price applicable to such Redemption (including a reasonably detailed description
of the calculation thereof). Notwithstanding such notice, outstanding Debentures shall remain convertible during the period from the date of such notice through the Redemption Date in accordance with
the provisions of Section 8 of this Agreement (and in any event shall remain 

3

 

convertible
until the Redemption Price is paid in respect thereof). In the event that less than all of the outstanding Debentures shall be called for Redemption, Debentures shall be redeemed  pro rata from the
holders of outstanding Debentures. 

	7.3
	DEBENTURES
PAYABLE ON REDEMPTION DATE. 

        Notice
of a Redemption having been given pursuant to Section 7.2, the Debentures shall, on the Redemption Date fixed for such Redemption, become due and payable at the applicable
Redemption Price, and from and after such Redemption Date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest payable as set forth herein), such
Debentures shall cease to bear interest in accordance with Article 6. If the amount payable in respect of any Debenture selected for Redemption shall not be so paid or made available for
payment, the unpaid amount shall, until paid, bear interest from the Redemption Date fixed for such Redemption at a rate equal to the Default Rate. The Company will promptly cancel all Debentures
redeemed by it. 

	7.4
	MANDATORY
REDEMPTION. 

        If
and to the extent the Company repurchases or redeems, or otherwise returns capital in respect of, any Stapled Shares (whether in the form of cash, securities or otherwise and whether
pursuant to a reduction of the nominal value of such Stapled Shares or not), the Company shall redeem a portion of the Debentures as shall equal the product of (x) the aggregate principal
amount of such Debentures then outstanding multiplied by (y) a fraction of which (I) the denominator shall be the total capital contributed to the Company in respect of the Stapled
Shares, less any previous repurchase, redemption or other return of capital in respect of such Stapled Shares, and (II) the numerator shall be the amount
of capital returned to the holders of Stapled Shares in such repurchase, redemption or other return of capital. Any redemption effected pursuant to this Section 7.4 shall be effected in
accordance with the terms and subject to the conditions set forth in this Section 7. 

 
 

8.     CONVERSION OF DEBENTURES.         

	8.1
	CONVERSION
PRIVILEGE. 

        Subject
to and upon compliance with the provisions of this Section 8, at the option of the holder thereof, any Debenture or any portion of the principal amount thereof may be
converted into that number of fully paid and nonassessable Ordinary Shares (calculated as to each conversion to the nearest 1/1000 of a share) as shall equal the quotient of (a) the sum of
(i) the principal amount to be so converted plus (ii) any accrued and unpaid interest payable in accordance with Section 6 in respect of dividends or distributions on Ordinary
Shares having a payment date on or prior to the Redemption Date, divided by (b) the Conversion Price, deter-mined as hereinafter provided, in effect at the time of such conversion. In case the
Debentures are called for Redemption, such conversion right in respect of the Debentures shall expire at the close of business on the Redemption Date, unless (i) notice of conversion under
Section 8.3 has been given prior to such time, or (ii) the Company defaults in making the payment due upon such Redemption. 

        In
the case of any Debenture which is converted, in whole or in part, after any re-cord date for the payment of any dividend or distribution in respect of Ordinary Shares and
on or prior to the date fixed for payment of such dividend or distribution, the interest due in accordance with Section 6 in respect of such dividend or distribution shall be payable, without
duplication, on such record date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Debenture is
registered at the close of business on such record date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Debenture which is converted, interest which
would become payable on any date falling after the date of conversion of such Debenture shall not be payable. 

4

  

	8.2
	CONVERSION
PRICE; AUTOMATIC ADJUSTMENT OF CONVERSION PRICE. 

        The
price at which Ordinary Shares shall be delivered upon conversion shall initially be US $5.15 aggregate principal amount per Ordinary Share (the "Conversion
Price"), which Conversion Price shall be subject to adjustment as set forth below. On March 31, June 30, September 30 and December 31 of each
calendar year, the Conversion Price shall automatically be adjusted such that the Conversion Price in effect on such date shall equal the product, rounded to the nearest ten decimal places, of
(a) the Conversion Price in effect as of the immediately pre-ceding quarterly adjustment multiplied by (b) 0.9878765474
(provided that, when calculating the Conversion Price as of any date other than the last day of a fiscal quarter, the Conversion Price shall be adjusted
pro rata for the partial quarterly period elapsed). Notwithstanding the foregoing, for purposes of the initial quarterly adjustment to be made on September 30, 2002 only, the reference to
"0.9878765474" in the preceding sentence shall be to "0.9936042994". 

	8.3
	EXERCISE
OF CONVERSION PRIVILEGE. 

        The
holder of any Debenture wishing to exercise the conversion privilege shall give the Company irrevocable written notice of such election at least five Business Days prior to the
Business Day designated in such notice as the date of conversion (the "Conversion Date"). Such notice also shall specify the principal amount of
Debentures to be converted. The holder of any Debenture to be converted shall, on or before the Conversion Date, surrender such Debenture, duly endorsed or assigned to the Company or in blank, at the
principal executive office of the Company. 

        Debentures
shall be deemed to have been converted immediately prior to the close of business on the Conversion Date, at the Conversion Price in effect on such Conversion Date, and at
such time the rights of the holders of such Debentures as holders shall cease, and the Per-son or Persons entitled to receive the Ordinary Shares issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the Conversion Date, the Company shall take such action as shall be necessary
under law to reflect the issuance of the number of full Ordinary Shares issuable upon such conversion, together with payment in lieu of any fraction of a share, as provided in Section 8.4. 

        In
the case of any Debenture which is converted in part only, upon such conversion the Company shall execute and deliver to the holder thereof, at the expense of the Company, a new
Debenture or Debentures in aggregate principal amount equal to the unconverted portion of the principal amount of such Debenture. 

	8.4
	FRACTIONS
OF SHARES. 

        No
fractional Ordinary Shares shall be issued upon conversion of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the same holder, at the
election of such holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Debentures (or specified
portions thereof) so converted. In lieu of any fractional Ordinary Share which would otherwise be issuable upon conversion of any Debenture or Debentures (or specified portions thereof), the Company
shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Fair Market Value per Ordinary Share determined as of the day of conversion. 

	8.5
	ADJUSTMENT
OF THE CONVERSION PRICE UPON CERTAIN EVENTS. 

        (a)   In
case the Company shall (i) pay a dividend on any class of its capital stock in Ordinary Shares (other than a dividend paid to holders of Ordinary Shares in
which the holders of Debentures participate pro rata pursuant to Section 6), (ii) subdivide the outstanding Ordinary Shares into a greater
number of shares or (iii) combine the outstanding Ordinary Shares into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted by multiplying
(A) the 

5

 

Conversion
Price at which Debentures were theretofore convertible by (B) a fraction of which (x) the denominator shall be the number of Ordinary Shares outstanding immediately following
such action and (y) the numerator shall be the number of shares of Ordinary Shares outstanding immediately prior thereto. Such adjustment shall be made whenever any event listed above shall
occur and shall become effective retroactively immediately after the record date in the case of a dividend and immediately after the effective date in the case of a subdivision or combination. 

        (b)   In
case the Company shall (i) issue to any Person rights or warrants entitling such Person to subscribe for or purchase Ordinary Shares at a price per Ordinary
Share (including the sale price, if any, of such rights or warrants) less than the greater of (A) the Fair Market Value per Ordinary Share on the date of issuance and (B) the Conversion
Price in effect on the date of issuance (such greater amount, the "Greater Price"), or (ii) issue to any Person any other securities convertible
into or exchangeable for Ordinary Shares for a consideration per Ordinary Share deliverable upon conversion or exchange thereof less than the Greater Price, then the Conversion Price in effect
immediately prior thereto shall be adjusted so that the Conversion Price shall be equal to the price determined by multiplying (x) the Conversion Price at which Debentures were theretofore
convertible by (y) a fraction of which (I) the denominator shall be the sum of (1) the number of Ordinary Shares outstanding on the date of issuance of the convertible or
exchangeable securities, rights or warrants and (2) the number of additional Ordinary Shares offered for subscription or purchase, or issuable upon such conversion or exchange, and
(II) the numerator shall be the sum of (1) the number of Ordinary Shares outstanding on the date of issuance of such convertible or exchangeable securities, rights or warrants and
(2) the number of additional Ordinary Shares which the aggregate purchase price or consideration referred to above to be paid at or prior to the issuance of such Ordinary Shares for the number
of Ordinary Shares so offered would purchase at the Greater Price. Such adjustment shall be made whenever such convertible or exchangeable securities, rights or warrants are issued, and shall become
effective immediately after the date of issuance of such securities. In the event the price per Ordinary Share deliverable upon exercise of any outstanding right or warrant to purchase or subscribe
for Ordinary Shares, or upon conversion or exchange of any securities convertible into or ex-changeable for Ordinary Shares, is adjusted or amended to an amount less than the Greater
Price, calculated as of the date of such adjustment, then the Conversion Price in effect immediately prior thereto shall be adjusted as provided in the immediately preceding sentence as if such right,
warrant or convertible or exchangeable security were newly issued by the Company on the date of such adjustment or amendment (taking into account any prior adjustment to the Conversion Price made on
account of such right, warrant or convertible or exchangeable security). The fore-going notwithstanding, upon the expiration of any right or warrant to purchase Ordinary Shares, the
issuance of which resulted in an adjustment in the Conversion Price pursuant to this Section 8.5(b), if any such right or warrant shall expire and shall not have been exercised, the Conversion
Price shall be recomputed immediately upon such expiration and effective immediately upon such expiration shall be increased to the price it would have been (taking into account any other adjustments
to the Conversion Price made pursuant to the provisions of this Section 8.5(b) after the issuance of such rights or warrants) had the adjustment of the Conversion Price made upon the issuance
of such rights or warrants been made on the basis of offering for subscription or purchase only that number of Ordinary Shares actually purchased upon the exercise of such rights or warrants. No
further adjustment shall be made upon exercise of any right, warrant, convertible security or exchangeable security if any adjustment shall have been made upon issuance of such security. 

        (c)   In
case the Company shall purchase or otherwise acquire any Ordinary Shares, or shall redeem the outstanding Ordinary Shares, at a price per share greater than the Fair
Market Value per Ordinary Share on the date of such event, or in case the Company shall purchase, redeem or otherwise acquire other securities convertible into or exchangeable for Ordinary Shares for
a consideration per Ordinary Share into which such security is convertible or ex-changeable greater than the Fair Market Value per Ordinary Share on the date of such event, then the
Conversion Price in effect immediately 

6

 

prior
thereto shall be adjusted as provided below so that the Conversion Price therefor shall be equal to the price determined by multiplying (A) the Conversion Price at which Debentures were
theretofore convertible by (B) a fraction of which (x) the denominator shall be the Fair Market Value per Ordinary Share on the date of such event, and (y) the numerator shall be
the Fair Market Value per Ordinary Share on the date of such event less the quotient of (1) the difference between (a) the aggregate consideration paid by the Company for all Ordinary
Shares (or, in the case of securities convertible into or exchangeable for Ordinary Shares, the aggregate consideration for all Ordinary Shares into which such security is convertible or exchangeable)
purchased, redeemed or acquired in such transaction or event and (b) the aggregate Fair Market Value of the number of Ordinary Shares (or, in the case of securities convertible into or
exchangeable for Ordinary Shares, the aggregate Fair Market Value of all Ordinary Shares into which such security is convertible or exchangeable) so purchased, re-deemed or acquired in,
and measured as of the date of, such transaction or event divided by (2) the number of Ordinary Shares outstanding on the date of the relevant event after giving effect to such purchase,
redemption or acquisition. Such adjustment shall be made whenever such Ordinary Shares or convertible or exchangeable securities are purchased, redeemed or acquired, and shall become effective
immediately after the purchase, redemption or acquisition of such securities. 

        (d)   In
case the Corporation shall issue or sell any Ordinary Shares at a price per share below the Greater Price on the date the Company commits or agrees to such sale or
issuance, then the Conversion Price in effect immediately prior thereto shall be adjusted so that the Conversion Price shall be equal to the price determined by multiplying (A) the Conversion
Price at which Debentures were theretofore convertible by (B) a fraction of which (x) the denominator shall be the sum of (1) the number of Ordinary Shares outstanding on the date
of issuance or sale of such Ordinary Shares and (2) the number of additional Ordinary Shares issued or sold, and (y) the numerator shall be the sum of (1) the number of Ordinary
Shares outstanding on the date of issuance or sale of such Ordinary Shares and (2) the number of additional Ordinary Shares which the aggregate offering price of the number of Ordinary Shares
so sold or issued would purchase at the Greater Price on the date the Company commits or agrees to such sale or issuance. Such adjustment shall be made whenever Ordinary Shares are issued or sold, and
shall become effective immediately after the issuance or sale of such securities. 

        (e)   The
Company may make such reductions in the Conversion Price, in addition to those required by paragraphs (a), (b), (c) and (d) of this Section 8.5,
as it considers to be advisable in order that any event treated for United States federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients or any of
their direct or indirect shareholders, members or partners. 

        (f)    For
the purposes of this Section 8.5, the number of Ordinary Shares out-standing at any time shall not include shares held in the treasury of the
Company. The Company shall not pay any dividend or make any distribution on Ordinary Shares held in the treasury of the Company, and shall not issue any rights or warrants in respect of Ordinary
Shares held in the treasury of the Company. 

	8.6
	NOTICE
OF ADJUSTMENTS OF CONVERSION PRICE. 

        Whenever
the Conversion Price is adjusted in accordance with Section 8.5: 

        (a)   the
Company shall compute the adjusted Conversion Price and shall pre-pare a certificate signed by the chief executive officer of the Company setting forth
the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed with the books and records of the Company;
and 

        (b)   a
notice stating that the Conversion Price has been adjusted and setting forth the adjusted Conversion Price shall promptly be mailed by the Company, together with a
copy of the certificate prepared in accordance with Section 8.6(a), to all holders of outstanding Debentures at their last addresses as they shall appear in the Debenture Register.

        In
case: 

        (a)   the
Company shall declare a dividend or any other distribution on its Or-dinary Shares; 

        (b)   the
Company shall authorize the granting to the holders of its Ordinary Shares of rights or warrants to subscribe for or purchase any shares of capital stock of any
class or of any other rights; 

        (c)   of

are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, lease conveyance, distribution or Liquidation is expected to become effective, and
the date as of which it is expected that holders of Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, lease conveyance, distribution or Liquidation. Notwithstanding the fore-going, the failure to provide or receive such notice or any
defect therein or in the delivery thereof shall not affect the validity of any action taken in connection with any of the matters described in clauses (a) through (d) above. 

	8.8
	COMPANY
TO RESERVE COMMON STOCK. 

        The
Company shall at all times reserve and keep available, free from pre-emptive rights, out of its authorized but unissued Ordinary Shares, for the purpose of effecting the

	8.9
	TAXES
ON CONVERSIONS. 

        The
Company will pay any and all transfer or stamp taxes that may be payable in respect of the issue or delivery of Ordinary Shares on conversion of Debentures pursuant hereto. The
Company shall not, however, be required to pay any income tax payable with respect to conversion of Debentures or any tax which may be payable in respect of any transfer involved in the issue and
delivery of Ordinary Shares in a name other than that of the holder of the Debenture or Debentures to be converted, and
no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that
such tax has been paid.

	8.12
	PROVISIONS
IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS. 

        In
case of any consolidation of the Company with or merger of the Company into any other Person, any merger of another Person into the Company (other than a merger which does not result
in any reclassification, conversion, exchange or cancellation of outstanding Ordinary Shares), or any sale, transfer, lease, conveyance or other distribution of all or substantially all of the assets
of the Company, the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver a supplement to this Agreement
providing that the holder of each Debenture shall have the right thereafter to convert such Debenture at any time, in whole or in part, into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, sale, transfer, lease, conveyance or other distribution by a holder of the number of Ordinary Shares (including fractional shares) of the Company into which
such Debenture would otherwise then be convertible (had such conversion taken place immediately prior to such consolidation, merger, sale, transfer, lease, conveyance or other distribution), assuming
such holder of Ordinary Shares (i) is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale, transfer, lease,
conveyance or other distribution was made, as the case may be ("constituent Person"), or an Affiliate of a constituent Person
(to the extent that any such Persons are treated differently than the other holders of Company securities in such transaction) and (ii) failed to exercise his rights of election, if any, as to
the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale, transfer, lease, conveyance or other distribution
(provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale, transfer, lease,
conveyance or other distribution is not the same for each Ordinary Share held immediately prior to such consolidation, merger, sale, transfer, lease, conveyance or other distribution by others than a
constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("non-electing
share"), then for the purpose of this Section the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale, transfer, lease,
conveyance or other distribution by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Such
supplement to this Agreement shall provide for adjustments which, for events subsequent to the effective date of the event which triggers the requirement of such supplemental indenture, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this Section 8. The above provisions of this Section 8.12 shall similarly apply to successive consolidations,
mergers, sales, transfers, leases, conveyances or other distributions. 

 
 

9.     AFFIRMATIVE COVENANTS.         

	9.1
	MAINTENANCE
OF EXISTENCE. 

        The
Company covenants that so long as any of the Debentures are outstanding, except as provided in Section 10.1, the Company will at all times preserve and keep in full force and
effect its existence under applicable law. Subject to Section 10.1, the Company will at all times preserve and keep in full force and effect the existence of each of its Subsidiaries under
applicable law (unless merged or consolidated into the Company or a Subsidiary) and all rights and franchises of the Company and its Subsidiaries unless, in the good faith judgment of the Company, the
termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise would not, individually or in the aggregate, have a Material Ad-verse
Effect. 

	9.2
	DEBENTURES
SUBORDINATE TO SENIOR OBLIGATIONS. 

        The
Company covenants and agrees, and each holder of a Debenture, by acceptance thereof, likewise covenants and agrees, (i) that, to the extent and in the manner set forth in this
Section 9.2, the Company's Senior Obligations, if any, will be senior in right of payment to the Debentures, and (ii) that the subordination provisions set forth in this
Section 9.2 are, and are intended to be, an 

9

 

inducement
and a consideration to each holder of any Senior Obligation, whether such Senior Obligation was created or acquired before or after the date of this Agreement, to acquire and continue to
hold, or to continue to hold, such Senior Obligation and such holder of Senior Obligations shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to
hold, or continuing to hold, such Senior Obligations. 

        (a)   As
used herein, "senior in right of payment to the Debentures" means that: (i) no part of the Debt shall have any
claim to the assets of the Company on a parity with or prior to the claim of the Senior Obligations; and (ii) unless and until the Senior Obligations then due and payable have been paid in
full, without the express prior written consent of all holders of such Senior Obligations, no Holder will take, demand (including by means of any legal action) or receive from the Company, and the
Company will not make, give or permit, directly or indirectly, by set-off, redemption, purchase or in any other manner, any payment of or security for the whole or any part of the Debt;  provided,
however, that (x) at any time, the Company may make, and the Holders may receive,
scheduled payments on account of the Debt in accordance with the terms hereof, except (I) if a default in the performance or observance of any term or condition relating to any Senior
Obligations (other than a default in the payment of any principal of, premium if any, or interest on the Senior Obligations) has occurred and is continuing that permits the holders of the Senior
Obligations to declare such Senior Obligations to be due and payable, the holders of Senior Obligations may give notice (a "Senior Blockage Notice") to
the Company (provided, however, no more than one Senior Blockage Notice may be given during any 365 consecutive day period) that until all Senior Obligations are paid in full, no scheduled payments
may be made by the Company on account of the Debt during the period ("Senior Blockage Period") commencing on the date of such Senior Blockage Notice and
ending on the earliest of: (A) 180 days after the date of such Senior Blockage Notice; (B) the date such default is cured or waived; and (C) the date that the holders of
the Senior Obligations shall have given notice to the Company of termination of the Senior Blockage Period, and (II) when a default in the payment of any principal of, premium if any, or
interest on the Senior Obligations has occurred and is continuing or would result therefrom, (y) upon the acceleration of the maturity of any Senior Obligations, the Holders may accelerate the
scheduled maturities of the Debentures if and to the extent permitted hereby at such time but such acceleration shall not give any Holder any right to take, demand (including by means of any legal
action) or receive from the Company, or the Company the right to make, give or permit, directly or indirectly, by set-off, redemption, purchase or in any other manner, any payment of or
security for the whole or any part of the Debentures unless and until the Senior Obligations have been paid in full, and (z) nothing contained herein shall restrict the right of holders of
Debentures to receive interest payments in accordance with Section 6 in respect of dividends or distributions on Ordinary Shares, or to convert the Debentures in accordance with
Section 8. 

        (b)   Any
payment or distribution of assets of the Company, whether in cash, property or securities, to which any Holder would be entitled except for the provisions hereof,
shall be paid or delivered by the Holder, or any receiver, trustee in bankruptcy, liquidating trustee, disbursing agent or other Person making such payment or distribution, to the holders of the
Senior Obligations or their representative, ratably in accordance with the amounts thereof, to the extent necessary to pay in full all Senior Obligations, before any payment or distribution shall be
made to any Holder. 

        (c)   The
expressions "prior payment in full," "payment in full," "paid in full" and any other similar terms or phrases when
used herein with respect to the Senior Obligations shall mean the payment in full in cash, in immediately available funds, of all of the Senior Obligations; and the expression  "any payment of or security for the whole or any
part of the Debt" and any other similar terms or phrases when used herein shall not be deemed to
include a payment or distribution of shares or other securities of the Company provided for by a plan of reorganization or readjustment authorized by an order or decree of a court of competent
jurisdiction in a reorganization proceeding under any applicable bankruptcy law or of any other corporation provided for by such plan of reorganization or 

10

 

readjustment,
which stock or securities are subordinated in right of payment to all then outstanding Senior Obligations to substantially the same extent as the Debentures are so subordinated as
provided in this Section 9.2. The consolidation of the Company with, or the merger of the Company into, another Person or a Liquidation of the Company following the sale, transfer, lease,
conveyance or other distribution of all or substantially all of the properties and assets of the Company substantially as an entirety to another Person upon the terms and conditions set forth in
Section 10.1 shall not be deemed a "proceeding" for the purposes of this Section 9.2 if the Person formed by such consolidation or into which the Company is merged or the Person which
acquires by sale, transfer, lease, conveyance or other distribution such properties and assets substantially as an entirety, as the case may be, shall, as a part of such consolidation, merger,
conveyance, transfer, lease or other disposition, comply with the conditions set forth in Section 10.1. 

        (d)   If
any payment or distribution, whether consisting of money, property or securities, is collected or received by any Holder in respect of the Debt, except payments
permitted hereunder, such Holder forthwith shall deliver the same to the holders of the Senior Obligations or their representative, ratably in accordance with the amounts thereof, in the form
received, duly endorsed to such holders or representative, if required, to be applied to the payment or prepayment of the Senior Obligations until the Senior Obligations are paid in full. Until so
delivered, such payment or distribution shall be held in trust by such Holder as the property of such holders of Senior Obligations, segregated from other funds and property held by the Holder. 

        (e)   As
used herein, "Senior Obligations" shall mean collectively the unpaid principal of, premium, if any, and interest on
(including, without limitation, interest accruing after the maturity date of any Senior Obligation and interest accruing after the filing of any petition in bankruptcy, or the commencement of any
insolvency, reorganization or like proceeding, relating to the Company, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) all
Indebtedness of the Company whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter incurred, in each case whether on ac-count of principal,
premium, interest, reimbursement obligations, fees, indemnities, costs, expenses or otherwise. 

        (f)    As
used herein, "Debt" shall mean collectively the unpaid principal of, premium, if any, and interest on (including,
without limitation, interest accruing after the maturity date of any Debenture and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency,
reorganization or like proceeding, relating to the Company, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) the Debentures,
whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter incurred, in each case whether on account of principal, premium, interest, reimbursement
obligations, fees, indemnities, costs, expenses or otherwise. 

	9.3
	TREATMENT
UNDER NETHERLANDS TAX LAWS 

        Holder
and the Company agree that the Debentures qualify as equity for Nether-lands tax purposes and further agree that if the treatment of the Debentures is relevant in connection with
(i) any Netherlands corporate income tax, capital tax or other tax return filed by the Company, the Holder or any of their respective affiliates or (ii) any other substantive
communication between the Company, the Holder or any of their respective affiliates, on the one hand, and the Netherlands tax authorities, on the other hand, the Company, Holder or such affiliate, as
applicable, shall treat the Debentures as equity, in accordance with the substantive economics of the Debentures, for Netherlands tax purposes, to the fullest extent permitted by applicable law. 

11

 

 
 

10.   NEGATIVE COVENANTS.         The Company covenants that so long as any of the Debentures are outstanding: 

	10.1
	MERGER,
CONSOLIDATION, ETC. 

        The
Company shall not consolidate with or merge with any other company or convey, transfer or lease or otherwise dispose of all or substantially all of its assets in a single transaction
or series of transactions to any Person unless: 

        (a)   the
successor formed by such consolidation or the survivor of such merger or the Person that acquires by conveyance, transfer or lease substantially all of the assets of
the Company as an entirety, as the case may be, shall be a solvent company organized and existing under the laws of the United States, any State thereof (including the District of Columbia), or the
Netherlands, and, if the Company is not the successor company, such company shall have executed and delivered to each holder of any Debentures its assumption of the due and punctual performance and
observance of each covenant and condition of this Agreement and the Debentures; and 

        (b)   immediately
after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing. 

        No
such conveyance, transfer, or other disposition of all or substantially all of the assets of the Company shall have the effect of releasing the Company or any successor company that
shall theretofore have become such in the manner prescribed in this Section 10.1 from its liability under this Agreement or the Debentures. 

	10.2
	FORBEARANCE
FROM RESTRICTIONS ON RIGHTS OF HOLDERS OF DEBENTURES. 

        The
Company will not enter into any agreement or instrument or otherwise agree to any covenant that would in any way limit the right of the holders of the Debentures to convert the
Debentures into Ordinary Shares. 

 
 

11.   PAYMENTS ON LIQUIDATION.         Upon a Liquidation, the holders of outstanding Debentures shall be entitled to receive, from what remains
of the Company's assets after payment of Indebtedness
and in preference to and in priority over the holders of Ordinary Shares and any other outstanding issues of capital stock of the Company (other than any issue of Preferred Shares of the Company that,
according to its terms and conditions, ranks pari passu with the Debentures), an amount per outstanding Debenture equal to the sum of (a) the
greater of (i) the sum of (x) the principal amount outstanding under such Debenture and (y) the Premium on such Debenture as of the date of such Liquidation, and (ii) such
amount as would be payable as a liquidating distribution in respect of the number of Ordinary Shares into which such Debenture was convertible into immediately prior to such Liquidation if such shares
were so converted at the Conversion Price in effect on the date immediately prior to such Liquidation (the greater of the amounts set forth in clauses (i) and (ii) above, the
"Liquidation Payment") and (b) any accrued and unpaid interest payable in accordance with Section 6 in respect of dividends or
distributions on Ordinary Shares having a payment date on or prior to the date of such Liquidation. After the Liquidation Payment and such accrued and unpaid interest has been paid in full to the
holders of Debentures (and any class of Preferred Shares of the Company that, according to its terms and conditions, ranks pari passu with the
Debentures), the remainder of the assets of the Company available for distribution to shareholders may be paid to the holders of Ordinary Shares and other outstanding shares of capital stock of the
Company in proportion to the aggregate nominal amount of such securities. If the assets of the Company are not sufficient to pay the Liquidation Payment in full 

12

 

to
the holders of outstanding Debentures, the holders of all outstanding Debentures shall share ratably in any such distribution. 

 
 

12.   EVENTS OF DEFAULT.         An "Event of Default" shall exist if any of the following
conditions or events shall occur and be continuing: 

        (a)   the
Company defaults in the payment of any principal or premium on any Debenture when the same becomes due and payable hereunder; or (b) the Company defaults in
the payment of any interest on any Debenture for more than ten Business Days after the same becomes due and payable; or (c) the Company defaults in the performance of or compliance with any
term contained in Section 10.1; or (d) the Company defaults in the performance of or compliance with any term contained herein (other than those referred to in paragraphs (a),
(b) and (c) of this Section 12) and such default is not remedied within 30 days after the earlier of (i) a Responsible Officer obtaining actual knowledge of such
default and (ii) the Company receiving written notice of such default from any holder of a Debenture (any such written notice to be identified as a "notice of default" and to refer specifically
to this paragraph (d) of Section 12); or (e) any representation or warranty made in writing by or on behalf of the Company or by any officer of the Company in this Agreement or in
any writing furnished in connection with the trans-actions contemplated hereby proves to have been false or incorrect in any material respect on the date as of which made; (f) the Company
(i) files, or consents by answer or otherwise to the filing against it of, a petition for relief or reorganization or arrangement or any other petition in bankruptcy, for liquidation or to take
advantage of any bankruptcy, insolvency, reorganization, moratorium or other similar law of any jurisdiction, (ii) makes an assignment for the benefit of its creditors, (iii) consents to
the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to it or with respect to any substantial part of its property, (iv) is adjudicated as
insolvent or to be liquidated, or (v) takes corporate action for the purpose of any of the foregoing; or (g) a court or governmental authority of competent jurisdiction enters an
or-der appointing, without consent by the Company or any of its significant subsidiaries, a custodian, receiver, trustee or other officer with similar powers with respect to it or with
respect to any substantial part of its property, or constituting an order for relief or approving a petition for relief or reorganization or any other petition in bankruptcy or for liquidation or to
take advantage of any bankruptcy or insolvency law of any jurisdiction, or ordering the liquidation of the Company or any of its significant subsidiaries, or any such petition shall be filed against
the Company or any of its significant subsidiaries and such petition shall not be dismissed within 60 days.

	13.1
	ACCELERATION.

        Subject
to Section 9.2: 

	(a)
	If
an Event of Default with respect to the Company described in paragraph (f) o2l(g) of Section 12 has occurred, all the Debentures then outstanding shall
automatically be-come immediately due and payable. 

        (b)   If
any other Event of Default has occurred and is continuing, any holder or holders of more than 50% in principal amount of the Debentures at the time outstanding may at
any time at its or their option, by notice or notices to the Company, declare all the Debentures then outstanding to be immediately due and payable. 

        (c)   If
any Event of Default described in paragraph (a) or (b) of Section 12 has occurred and is continuing, any holder or holders of Debentures at the
time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Debentures held by it or them to be immediately due and
payable. 

13

  

        Upon any Debentures becoming due and payable under this Section 13.1, whether automatically or by declaration, such Debentures will forthwith mature and the entire unpaid
principal amount of such Debentures, plus all accrued and unpaid interest thereon payable in accordance with Section 6 shall all be immediately due and payable, in each and every case without
presentment, demand, protest or further notice, all of which are hereby waived. From and after the time at which the Debentures become due and payable in accordance with this Section 13.1, the
full amount due and payable thereunder shall accrue interest at the Default Rate. 

	13.2
	OTHER
REMEDIES. 

        If
any Default or Event of Default has occurred and is continuing, and irrespective of whether any Debentures have become or have been declared immediately due and payable under
Section 13.1, the holders of 50% or more in principal amount of the Debentures then outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity
or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Debenture, or for an injunction against a violation of any of the terms hereof or
thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 

        Notwithstanding
the foregoing, the holder of any Debenture shall have the right, which is absolute and unconditional, to receive payment of the principal of, premium, if any, and
interest on such Debenture and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such holder. 

	13.3
	RESCISSION.

        At
any time after any Debentures have been declared due and payable pursuant to clause (b) of Section 13.1, the holders of not less than 25% in principal amount of the
Debentures then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the
Debentures, all principal of and premium, if any, on any Debentures that are due and payable other than by reason of such declaration and are unpaid, and all interest on such overdue principal and (to
the extent permitted by applicable law) any overdue interest in respect of the Debentures, at the Default Rate, (b) all Events of Default and Defaults, other
than nonpayment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 18, and (c) no judgment or decree has been
entered for the payment of any monies due pursuant hereto or to the Debentures. No rescission and annulment under this Section 13.3 will extend to or affect any subsequent Event of Default or
Default or impair any right consequent thereon.

	NO
WAIVERS OR ELECTION OF REMEDIES, EXPENSES, ETC. 

        No
course of dealing and no delay on the part of any holder of any Debenture in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such
holder's rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Debenture upon any holder thereof shall be exclusive of any other right, power or remedy referred
to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 16, the Company will pay to the
holder of each Debenture on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 13,
including, without limitation, reasonable attorneys' fees, expenses and disbursements.

Register"). The name and ad-dress of each holder of one or more Debentures, each transfer thereof and the name and address of each transferee of one or more
Debentures shall be registered in such Debenture Register. The Company shall keep the Debenture Register together with its shareholder register, and shall include a note in its shareholder register to
the effect that certain Ordinary Shares listed therein are stapled to Debentures as set forth in the Debenture Register. Prior to due presentment for registration of transfer, the Person in whose name
any Debenture shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary.
The Company shall give to any holder of at least US $15,000,000.00 aggregate principal
amount of Debentures (which amount shall be reduced pro rata in the case of partial Redemptions or conversions), promptly upon re-quest therefor, a complete and correct copy of the names
and addresses of all registered holders of Debentures. 

	14.2
	TRANSFER
AND EXCHANGE OF DEBENTURES. 

        Subject
to Section 14.4, upon surrender of any Debenture at the principal executive office of the Company for registration of transfer or exchange (and in the case of a surrender
for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of such Debenture or his attorney duly authorized in writing and
accompanied by the address for notices of each transferee of such Debenture or part thereof), the Company shall execute and deliver, at the Company's expense (except as provided below), one or more
new Debentures (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Debenture. Each such new Debenture
shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Debenture shall be dated and bear interest from the date to which
interest shall have been paid on the surrendered Debenture or dated the date of the surrendered Debenture if no interest shall have been paid thereon. The Company may require payment of a sum
sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Debentures. Debentures shall not be transferred in denominations of less than US $1,000.00. Any
transferee, by its acceptance of a Debenture registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 4.3. 

	14.3
	REPLACEMENT
OF DEBENTURES. 

        Upon
receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Debenture, and (a) in the case of
loss, theft or destruction, of indemnity reasonably satisfactory to it, or (b) in the case of mutilation, upon surrender and cancellation thereof, the Company at its own expense shall execute
and deliver, in lieu thereof, a new Debenture, dated the date hereof, in replacement of such Debenture. 

	14.4
	DEBENTURES
STAPLED TO ORDINARY SHARES. 

        The
Debenture Register shall include, for each Debenture listed therein, the identification numbers (as such appears in the Company's shareholder register) of the Stapled Shares stapled
to such Debenture. Notwithstanding anything contained herein to the contrary, a holder may not Transfer any Debenture (or portion thereof) unless such holder simultaneously Transfers to the transferee
thereof one whole Ordinary Share for each US $1,000.00 aggregate principal amount of Debentures; provided that this sentence shall not apply to
(i) the redemption of any Debenture pursuant to Section 7, (ii) the Transfer of any Debenture to an Affiliate of such holder or to the Company, or (iii) the exchange of any
Debenture or Debentures solely for a Debenture or Debentures representing different principal 

15

 

amounts.
Any Transfer of Debenture without a Transfer of the corresponding Stapled Share or Stapled Shares, to the same person as such Debenture is Transferred to, shall be invalid and void and shall
not be binding on the Company. Upon any Transfer of Ordinary Shares held by a holder of Debentures, such holder shall be deemed to have simultaneously Transferred, to the same transferee as such
Ordinary Shares have been transferred to, a portion of the Debentures held by such holder as shall equal the principal amount of Debentures to which such Ordinary Shares would be considered Stapled
Shares. The ratio of one whole Ordinary Share per US $1,000.00 aggregate principal amount of Debentures shall be adjusted proportionately to reflect partial Redemptions, and any reclassification of,
or adjustment to the number of outstanding, Ordinary Shares, or any repurchase, redemption or other similar transaction relating to the outstanding Ordinary Shares. 

 
 

15.   PAYMENTS ON DEBENTURES.         Unless otherwise agreed between the Company and Holder, payments of principal and interest becoming due
and payable on the Debentures shall be made United States
dollars in Amsterdam, The Netherlands, at the principal office of the Company. The Company may at any time, by notice to each holder of a Debenture, change the place of payment of the Debentures so
long as such place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction. 

 
 

16.   EXPENSES, ETC.         

	16.1
	TRANSACTION

        The
Company will pay all reasonable out-of-pocket fees and expenses in connection with this Agreement or the Debentures, including, without limitation:
(a) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement or the Debentures or in responding to any

transactions contemplated hereby and by the Debentures. The Company will pay, and will save Holder and each other holder of a Debenture harmless from, all claims in respect of any fees, costs or
expenses if any, of brokers and finders or professional advisors. 

	16.2
	SURVIVAL.

obligations of the Company under this Section 16 will survive the payment or transfer of any Debenture, the enforcement, amendment or waiver of any provision of this Agreement
or the Debentures, and the termination of this Agreement. 

 
 

17.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.         All representations and warranties contained herein shall survive
the execution and delivery of this Agreement and the Debentures, the purchase or transfer by
Holder of any Debenture or portion thereof or interest therein and the payment of any Debenture, and may be relied upon by any subsequent holder of a Debenture, regardless of any investigation made at
any time by or on behalf of Holder or any other holder of a Debenture. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this
Agreement shall be deemed representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement and the Debentures embody the entire agreement and
understanding between Holder and the Company, and supersede all prior agreements and understandings, relating to the subject matter hereof.

18.   AMENDMENT AND WAIVER.         

	18.1
	REQUIREMENTS.

        This
Agreement and the Debentures may be amended, and the observance of any term hereof or of the Debentures may be waived (either retroactively or prospectively), with (and only with)
the written consent of the Company and the Required Holders, except that no such amendment or waiver may, without the written consent of the holder of each Debenture at the time outstanding affected
thereby, (i) subject to the provisions of Section 13 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or
change the time of payment or method of computation of interest on, the Debentures, (ii) change the percentage of the principal amount of the Debentures the holders of which are required to

	18.2
	SOLICITATION
OF HOLDERS OF DEBENTURES. 

        (a)   Solicitation. The Company will provide each holder of the Debentures (irrespective of the amount of Debentures then owned
by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an in-formed and considered decision with respect to any
proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Debentures. The Company will deliver executed or true and correct copies of each amendment, waiver or consent
effected pursuant to the provisions of this Section 18 to each holder of outstanding Debentures promptly following the date on which it is executed and delivered by, or receives the consent or
approval of, the requisite holders of Debentures. 

        (b)   Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, or grant any security, to any holder of Debentures as consideration for or as an inducement to the entering into by any holder of Debentures of
any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each holder of
Debentures then outstanding that consents thereto. 

	18.3
	BINDING
EFFECT, ETC. 

        Any
amendment or waiver consented to as provided in this Section 18 applies equally to all holders of Debentures and is binding upon them and upon each future holder of any
Debenture and upon the Company without regard to whether such Debenture has been marked to indicate such amendment or
waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No
course of dealing between the Company and the holder of any Debenture nor any delay in exercising any rights hereunder or under any Debenture shall operate as a waiver of any rights of any holder of
such Debenture. 

	18.4
	DEBENTURES
HELD BY COMPANY, ETC. 

        Solely
for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Debentures then outstanding approved or consented to any
amendment, waiver or consent to be given under this Agreement or the Debentures, or have directed the taking of any action provided herein or in the Debentures to be taken upon the direction of the

	No. [            ]	 	August    , 2002	 	US $[            ]

        FOR
VALUE RECEIVED, the undersigned, PARADIGM GEOTECHNOLOGY B.V. (herein called the "Company"), a private company with limited liability
(besloten vennootschap met beperkte aansprakelykheid) organized under Netherlands law, hereby promises to pay to
[                        ], or registered assigns, the principal sum of US $
[                        ] UNITED STATES DOLLARS. This Debenture is one of a series of
Convertible Subordinated Debentures (herein called the "Debentures"), stapled to ordinary shares, nominal value €0.01 per share, of the
Company ("Ordinary Shares"), issued pursuant to the Debenture Agreement, dated as of August    , 2002, by and between the Company and

terms used herein without otherwise being defined have the respective meanings assigned to such terms in the Agreement. In the case of any conflict between the provisions of this Debenture and the
Agreement, the provisions of the Agreement shall control. 

        Payments

Debenture, or in case this Debenture is called for redemption, then in respect of this Debenture until and including, but (unless the Company defaults in making the payment due upon redemption) not
after, the close of business on the Redemption Date, to convert this Debenture (or any portion of the principal amount hereof) into that number of fully paid and nonassessable Ordinary Shares
(calculated as to each conversion to the nearest 1/1000 of a share) as shall equal the quotient of (a) the sum of (i) the principal amount to be so converted plus (ii) any accrued
and unpaid interest payable in accordance with Section 6 of the Agreement in respect of dividends or distributions on Ordinary Shares having a payment date on or prior to the Redemption Date,
divided by (b) the Conversion Price, determined in accordance with the Agreement, in effect at the time of such conversion. The Conversion Price is subject to adjustment as provided in the
Agreement. In addition, the Agreement provides that in case of certain consolidations or mergers to which the Company is a party or the sale, transfer, lease conveyance or other distribution of all or
substantially all of the assets of the Company, the Agreement shall be supplemented so that the holder of this Debenture shall have the right thereafter to convert such Debenture into the kind and
amount of securities, cash and other property

such Debenture would otherwise then be convertible (assuming such conversion had been effected immediately prior to the consummation of such consolidation, merger, sale, transfer, lease, conveyance or
other distribution), subject to certain assumptions specified in the Agreement. 

        This
Debenture is subordinated to the prior payment of the Senior Obligations to the extent and in the manner set forth in the Agreement and by its acceptance hereof the holder of this
Debenture agrees to such subordination. 

        This
Debenture is a registered Debenture and, as provided in the Agreement, upon surrender of this Debenture for registration of transfer, duly endorsed, or accompanied by a written
instrument of transfer duly executed, by the registered holder hereof or such holder's attorney duly authorized in writing, a new Debenture or Debentures for a like principal amount will be issued to,
and registered in the name of, the transferee; provided that any transfer of this Debenture (or any portion thereof) must comply with
Section 14.4 of the Agreement. Prior to due presentment for registration of transfer, the Company may treat the person in whose name this Debenture is registered as the owner hereof for the
purpose of receiving payment and for all other purposes, and the Company will not be affected by any notice to the contrary. 

        This

DEBENTURE AGREEMENT    
    

        THIS DEBENTURE AGREEMENT (as amended or supplemented from time to time, the "Agreement"), dated as of
August 11, 2006, is made by and between PARADIGM GEOTECHNOLOGY B.V., a private company with limited liability (besloten vennootschap met beperkte
aansprakelijkheid) organized under Netherlands law (the "Company"), and the holders party identified in  Schedule A attached
hereto (the "Holders" and each a
"Holder"). 

        WHEREAS,
the Holders and the Company are party to that certain share purchase and contribution agreement, by and among the Company, Paradigm Geotechnology Holdings B.V, and the sellers
party thereto, dated as of July 5, 2006 as amended and restated pursuant to an amended and restated share purchase agreement dated August 11, 2006 (the "Share
Purchase and Contribution Agreement"); 

        WHEREAS,
pursuant to the Share Purchase and Contribution Agreement the Holders contributed shares of Earth Decision Sciences S.A., a societe anonyme, organized and existing under the
laws of France ("EDS"); 

        WHEREAS,
pursuant to the Share Purchase and Contribution Agreement, Holders have (or will) contribute shares of EDS in to the Company in exchange for ordinary shares of the Company and
the Debentures (as defined herein) (the "Contribution"); 

        WHEREAS,
Holders and the Company desired that the Holders would receive Ordinary Shares and convertible preference shares in the share capital of the Company in exchange for the
Contribution; 

        WHEREAS,
Holders and the Company have considered that the Netherlands company law imposes certain undesirable restraints in connection with convertible preference shares; 

        WHEREAS,
Holders and the Company desire to achieve, as nearly as is practicable, the economic effect of issuing Ordinary Shares and convertible preference shares of the Company in
exchange for the Contribution, and in particular desire the full Contribution to increase the economic potential of the Company; 

        WHEREAS,
as a result of the foregoing, Holders and the Company desire for the Company to issue in exchange for the above Contribution (i) 1 Ordinary Share per $9.15 principal
amount and (ii) Debentures having an aggregate principal amount of US $9.15 multiplied by appropriate number of debentures to be issued; and 

        WHEREAS,
Holders and the Company desire to treat the Debentures, which are debt obligations for purposes of the Netherlands company law, as equity for Netherlands tax law purposes. 

        NOW,
THEREFORE, in consideration of the foregoing premises and of the mutual covenants and agreements herein contained, each parry hereto agrees as follows for the benefit of the other
and for the equal and ratable benefit of the holders of the Debentures (as defined below). 

 
 

1.     AUTHORIZATION OF DEBENTURES.         

        The
Company has authorized the issue and sale of US $8,465,442.75 aggregate principal amount of its Convertible Subordinated Debentures (the
"Debentures," such term to include any such debentures issued in substitution therefor pursuant to Section 14 of this Agreement), which are
stapled to 925,185 (the "Stapled Shares"). The Debentures shall be substantially in the form set out in  Exhibit 1 hereto, with such changes therefrom,
if any, as may be approved by the Holders and the Company. Certain capitalized terms used in this
Agreement are defined in Schedule B hereto; references to a "Schedule" or an "Exhibit" are, unless otherwise specified, to a Schedule or an
Exhibit attached to this Agreement. 

1

 

 
 

2.     ISSUE OF DEBENTURES.         

        Subject
to the terms and conditions of this Agreement, the Company hereby issues and sells to Holders, and Holders hereby purchases from the Company, in partial consideration for the
Contribution, an aggregate of US $8,465,442.75 in principal amount of Debentures at 100% of the principal amount thereof. 

 
 

3.     REPRESENTATIONS AND WARRANTIES OF THE COMPANY.         

	3.1
	PRIVATE
OFFERING BY THE COMPANY. 

        Neither
the Company nor anyone acting on its behalf has offered the Debentures or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, any person other than Holders, which has been offered the Debentures at a private sale for investment. Neither the Company nor anyone acting on its
behalf has taken, or will take, any action that would subject the issuance or sale of the Debentures to the registration requirements of Section 5 of the Securities Act. 

 
 

4.     REPRESENTATIONS OF THE HOLDER.         

	4.1
	PURCHASE
FOR INVESTMENT. 

        Each
Holder represents that it is purchasing the Debentures for its own account and not with a view to the public distribution thereof, provided that the disposition of its property
shall at all times be within its control. Each Holder understands that the Debentures have not been registered under the Securities Act and may be resold only if registered pursuant to the provisions
of the Securities Act or if an exemption from registration is available, except under circumstances where neither such registration nor such an exemption is required by law, and that the Company is
not required to register the Debentures. 

 
 

5.     TERM.         

        Debentures
shall have a perpetual term, without any stated maturity date. 

 
 

6.     PAYMENT OF INTEREST.         

        Holders
of Debentures shall be entitled to receive interest payments in an amount per Debenture equal to that sum calculated as if the Debentures participated equally and ratably with
the holders of Ordinary Shares in all dividends and distributions paid (whether in the form of cash, securities or otherwise) on Ordinary Shares determined as if immediately prior to each record date
for payment of such dividend or distribution in respect of Ordinary Shares, all Debentures then outstanding were converted into Ordinary Shares in the manner provided under Section 8, and at
the Conversion Price in effect on such record date. Accordingly, each holder of Debentures shall receive on the payment date of such dividend or distribution on Ordinary Shares an amount per Debenture
of cash, securities or other property so distributed as such holder would have received had such holder converted, at the Conversion Price in effect on the record date for the payment of such dividend
or distribution, all of the principal amount of such Debenture into Ordinary Shares immediately prior to the record date for the payment of such dividend or distribution. 

 
 

7.     REDEMPTION OF THE DEBENTURES.         

	7.1
	REDEMPTION;
REDEMPTION PRICE. 

        At
any time or from time to time, subject to any holder's right to first convert Debentures into Ordinary Shares, the Company may redeem (a
"Redemption") the Debentures in whole or in part at a redemption price per Debenture equal to the Redemption Price as of the Redemption Date, together 

2

 

with
any accrued and unpaid interest payable in accordance with Section 6 in respect of dividends or distributions on Ordinary Shares having a payment date on or prior to the Redemption Date.
For purposes of this Agreement, the "Redemption Price" means, as of any date, an amount per Debenture equal to the greater of (i) the sum of
(x) the principal amount outstanding under such Debenture and (y) the Premium as of such date, and (ii) the product of multiplying (x) the total number of Ordinary Shares
that would be issuable upon conversion of such Debenture immediately prior to such date, at the Conversion Price in effect on such date, by (y) the Fair Market Value per Ordinary Share
determined as of such date. For purposes of this Agreement, the "Premium" means, as of any date, an amount per Debenture equal to the amount of
interest, computed on the basis of a 360-day year of twelve 30-day months, that would have accrued at an annual rate of 5.0% (compounded quarterly) on the principal amount of
such Debenture during the period commencing on the date hereof through such date. 

        In
the case of any Debenture which is redeemed in part only, upon such Redemption the Company shall execute and deliver to the holder thereof, at the expense of the Company, a new
Debenture or Debentures in aggregate principal amount equal to the portion of the principal amount of such Debenture that has not been redeemed. In the case of any Debenture which is redeemed, in
whole or in part, after any record date for the payment of any dividend or distribution in respect of Ordinary Shares and on or prior to the date fixed for payment of such dividend or distribution,
the interest due in accordance with Section 6 in respect of such dividend or distribution shall be payable, without duplication, to the holders on such record date notwithstanding such
Redemption, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Debenture is registered at the close of business on such record date. 

	7.2
	ELECTION
TO REDEEM; NOTICE TO HOLDERS. 

        The
Company shall give each holder of Debentures written notice of a Redemption not less than two Business Days prior to the date fixed for such Redemption (the
"Redemption Date"), specifying the Redemption Date and the Redemption Price applicable to such Redemption (including a reasonably detailed description
of the calculation thereof). Notwithstanding such notice, outstanding Debentures shall remain convertible during the period from the date of such notice through the Redemption Date in accordance with
the provisions of Section 8 of this Agreement (and in any event shall remain convertible until the Redemption Price is paid in respect thereof). In the event that less than all of the
outstanding Debentures shall be called for Redemption, Debentures shall be redeemed pro rata from the holders of outstanding Debentures. 

	7.3
	DEBENTURES
PAYABLE ON REDEMPTION DATE. 

        Notice
of a Redemption having been given pursuant to Section 7.2, the Debentures shall, on the Redemption Date fixed for such Redemption, become due and payable at the applicable
Redemption Price, and from and after such Redemption Date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest payable as set forth herein), such
Debentures shall cease to bear interest in accordance with Article 6. If the amount payable in respect of any Debenture selected for Redemption shall not be so paid or made available for
payment, the unpaid amount shall, until paid, bear interest from the Redemption Date fixed for such Redemption at a rate equal to the Default Rate. The Company will promptly cancel all Debentures
redeemed by it. 

	7.4
	MANDATORY
REDEMPTION. 

        If
and to the extent the Company repurchases or redeems, or otherwise returns capital in respect of, any Stapled Shares (whether in the form of cash, securities or otherwise and whether
pursuant to a reduction of the nominal value of such Stapled Shares or not), the Company shall redeem a portion of the Debentures as shall equal the product of (x) the aggregate principal
amount of such Debentures then outstanding multiplied by (y) a fraction of which (I) the denominator shall be the total capital contributed to the Company in respect of the Stapled
Shares, less any previous repurchase, redemption 

3

 

or
other return of capital in respect of such Stapled Shares, and (II) the numerator shall be the amount of capital returned to the holders of Stapled Shares in such repurchase, redemption or
other return of capital. Any redemption effected pursuant to this Section 7.4 shall be effected in accordance with the terms and subject to the conditions set forth in this Section 7. 

 
 

8.     CONVERSION OF DEBENTURES.         

	8.1
	CONVERSION
PRIVILEGE. 

        Subject
to and upon compliance with the provisions of this Section 8, at the option of the holder thereof, any Debenture or any portion of the principal amount thereof may be
converted into that number of fully paid and nonassessable Ordinary Shares (calculated as to each conversion to the nearest 1/1000 of a share) as shall equal the quotient of (a) the sum of
(i) the principal amount to be so converted plus (ii) any accrued and unpaid interest payable in accordance with Section 6 in respect of dividends or distributions on Ordinary
Shares having a payment date on or prior to the Redemption Date, divided by (b) the Conversion Price, determined as hereinafter provided, in effect at the time of such conversion. In case the
Debentures are called for Redemption, such conversion right in respect of the Debentures shall expire at the close of business on the Redemption Date, unless (i) notice of conversion under
Section 8.3 has been given prior to such time, or (ii) the Company defaults in making the payment due upon such Redemption. 

        In
the case of any Debenture which is converted, in whole or in part, after any record date for the payment of any dividend or distribution in respect of Ordinary Shares and on or prior
to the date fixed for payment of such dividend or distribution, the interest due in accordance with Section 6 in respect of such dividend or distribution shall be payable, without duplication,
on such record date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Debenture is registered at
the close of business on such record date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Debenture which is converted, interest which would become
payable on any date falling after the date of conversion of such Debenture shall not be payable. 

	8.2
	CONVERSION
PRICE; AUTOMATIC ADJUSTMENT OF CONVERSION PRICE. 

        The
price at which Ordinary Shares shall be delivered upon conversion shall initially be US $9.15 aggregate principal amount per Ordinary Share (the "Conversion
Price"), which Conversion Price shall be subject to adjustment as set forth below. On March 31, June 30, September 30 and December 31 of each
calendar year, the Conversion Price shall automatically be adjusted such that the Conversion Price in effect on such date shall equal the product, rounded to the nearest ten decimal places, of
(a) the Conversion Price in effect as of the immediately preceding quarterly adjustment multiplied by (b) 0.9878765474 (provided that,
when calculating the Conversion Price as of any date other than the last day of a fiscal quarter, the Conversion Price shall be adjusted pro rata for the partial quarterly period elapsed). 

	8.3
	EXERCISE
OF CONVERSION PRIVILEGE.

	(a)
	Conversion
at the Option of a Holder 

        Any
holder of any Debenture wishing to exercise the conversion privilege shall give the Company irrevocable written notice of such election at least five Business Days prior to the
Business Day designated in such notice as the date of conversion (the "Optional Conversion Date"). Such notice also shall specify the principal amount
of Debentures to be converted. The holder of any Debenture to be converted shall, on or before the Optional Conversion Date, surrender such Debenture, duly endorsed or assigned to the Company or in
blank, at the principal executive office of the Company. 

4

 

	(b)
	Mandatory
Conversion 

        In
the event that any or all of the debentures (the "Existing Debentures") outstanding under that certain Debenture Agreement (as amended
or supplemented from time to time, the "Existing Debenture Agreement"), dated as of August            , 2002, made by and between PARADIGM
GEOTECHNOLOGY B.V., a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) organized under Netherlands law (the
"Company"), and PARADIGM GEOTECHNOLOGY HOLDINGS B.V., a private company with limited liability (besloten vennootschap met
beperkte aansprakelijkheid) organized under Netherlands law, are converted into Ordinary Shares, an amount of the Debentures (the "Converted
Amount") equal to the product of (x) the amount of Debentures then outstanding, multiplied by a fraction, the numerator of which shall equal (y) the principal
amount of the Existing Debentures that were converted, and the denominator of which shall equal (z) the principal amount of the Existing Debentures that were outstanding immediately prior to
such conversion, shall automatically convert into Ordinary Shares on the date such Existing Debentures are converted (a "Mandatory Conversion Date" and,
together with any Optional Conversion Date, a "Conversion Date"). The Holders and the Company agree that there can be more than one Mandatory Conversion
Date. 

        Debentures
shall be deemed to have been converted immediately prior to the close of business on the Conversion Date, at the Conversion Price in effect on such Conversion Date, and at
such time the rights of the holders of such Debentures as holders shall cease, and the Person or Persons entitled to receive the Ordinary Shares issuable upon conversion shall be treated for all
purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the Conversion Date, the Company shall take such action as shall be necessary under
law to reflect the issuance of the number of full Ordinary Shares issuable upon such conversion, together with payment in lieu of any fraction of a share, as provided in Section 8.4. 

        In
the case of any Debenture which is converted in part only, upon such conversion the Company shall execute and deliver to the holder thereof, at the expense of the Company, a new
Debenture or Debentures in aggregate principal amount equal to the unconverted portion of the principal amount of such Debenture. 

	8.4
	FRACTIONS
OF SHARES. 

        No
fractional Ordinary Shares shall be issued upon conversion of Debentures. If more than one Debenture shall be surrendered for conversion at one time by the same holder, at the
election of such holder, the number of full shares which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Debentures (or specified
portions thereof) so converted. In lieu of any fractional Ordinary Share which would otherwise be issuable upon conversion of any Debenture or Debentures (or specified portions thereof), the Company
shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Fair Market Value per Ordinary Share determined as of the day of conversion. 

	8.5
	ADJUSTMENT
OF THE CONVERSION PRICE UPON CERTAIN EVENTS. 

        (a)   In
case the Company shall (i) pay a dividend on any class of its capital stock in Ordinary Shares (other than a dividend paid to holders of Ordinary Shares in
which the holders of Debentures participate pro rata pursuant to Section 6), (ii) subdivide the outstanding Ordinary Shares into a greater
number of shares or (iii) combine the outstanding Ordinary Shares into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted by multiplying
(A) the Conversion Price at which Debentures were theretofore convertible by (B) a fraction of which (x) the denominator shall be the number of Ordinary Shares outstanding
immediately following such action and (y) the numerator shall be the number of shares of Ordinary Shares outstanding immediately prior thereto. Such adjustment shall be made whenever any event
listed above shall occur and shall become 

5

 

effective
retroactively immediately after the record date in the case of a dividend and immediately after the effective date in the case of a subdivision or combination. 

        (b)   In
case the Company shall (i) issue to any Person rights or warrants entitling such Person to subscribe for or purchase Ordinary Shares at a price per Ordinary
Share (including the sale price, if any, of such rights or warrants) less than the greater of (A) the Fair Market Value per Ordinary Share on the date of issuance and (B) the Conversion
Price in effect on the date of issuance (such greater amount, the "Greater Price"), or (ii) issue to any Person any other securities convertible
into or exchangeable for Ordinary Shares for a consideration per Ordinary Share deliverable upon conversion or exchange thereof less than the Greater Price, then the Conversion Price in effect
immediately prior thereto shall be adjusted so that the Conversion Price shall be equal to the price determined by multiplying (x) the Conversion Price at which Debentures were theretofore
convertible by (y) a fraction of which (I) the denominator shall be the sum of (1) the number of Ordinary Shares outstanding on the date of issuance of the convertible or
exchangeable securities, rights or warrants and (2) the number of additional Ordinary Shares offered for subscription or purchase, or issuable upon such conversion or exchange, and
(II) the numerator shall be the sum of (1) the number of Ordinary Shares outstanding on the date of issuance of such convertible or exchangeable securities, rights or warrants and
(2) the number of additional Ordinary Shares which the aggregate purchase price or consideration referred to above to be paid at or prior to the issuance of such Ordinary Shares for the number
of Ordinary Shares so offered would purchase at the Greater Price. Such adjustment shall be made whenever such convertible or exchangeable securities, rights or warrants are issued, and shall become
effective immediately after the date of issuance of such securities. In the event the price per Ordinary Share deliverable upon exercise of any outstanding right or warrant to purchase or subscribe
for Ordinary Shares, or upon conversion or exchange of any securities convertible into or exchangeable for Ordinary Shares, is adjusted or amended to an amount less than the Greater Price, calculated
as of the date of such adjustment, then the Conversion Price in effect immediately prior thereto shall be adjusted as provided in the immediately preceding sentence as if such right, warrant or
convertible or exchangeable security were newly issued by the Company on the date of such adjustment or amendment (taking into account any prior adjustment to the Conversion Price made on account of
such right, warrant or convertible or exchangeable security). The foregoing notwithstanding, upon the expiration of any right or warrant to purchase Ordinary Shares, the issuance of which resulted in
an adjustment in the Conversion Price pursuant to this Section 8.5(b), if any such right or warrant shall expire and shall not have been exercised, the Conversion Price shall be recomputed
immediately upon such expiration and effective immediately upon such expiration shall be increased to the price it would have been (taking into account any other adjustments to the Conversion Price
made pursuant to the provisions of this Section 8.5(b) after the issuance of such rights or warrants) had the adjustment of the Conversion Price made upon the issuance of such rights or
warrants been made on the basis of offering for subscription or purchase only that number of Ordinary Shares actually purchased upon the exercise of such rights or warrants. No further adjustment
shall be made upon exercise of any right, warrant, convertible security or exchangeable security if any adjustment shall have been made upon issuance of such security. 

        (c)   In
case the Company shall purchase or otherwise acquire any Ordinary Shares, or shall redeem the outstanding Ordinary Shares, at a price per share greater than the Fair
Market Value per Ordinary Share on the date of such event, or in case the Company shall purchase, redeem or otherwise acquire other securities convertible into or exchangeable for Ordinary Shares for
a consideration per Ordinary Share into which such security is convertible or exchangeable greater than the Fair Market Value per Ordinary Share on the date of such event, then the Conversion Price in
effect immediately prior thereto shall be adjusted as provided below so that the Conversion Price therefor shall be equal to the price determined by multiplying (A) the Conversion Price at
which Debentures were theretofore convertible by (B) a fraction of which (x) the denominator shall be the Fair Market Value per Ordinary Share on the date of such event, and
(y) the numerator shall be the Fair Market Value per Ordinary 

6

 

Share
on the date of such event less the quotient of (1) the difference between (a) the aggregate consideration paid by the Company for all Ordinary Shares (or, in the case of securities
convertible into or exchangeable for Ordinary Shares, the aggregate consideration for all Ordinary Shares into which such security is convertible or exchangeable) purchased, redeemed or acquired in
such transaction or event and (b) the aggregate Fair Market Value of the number of Ordinary Shares (or, in the case of securities convertible into or exchangeable for Ordinary Shares, the
aggregate Fair Market Value of all Ordinary Shares into which such security is convertible or exchangeable) so purchased, redeemed or acquired in, and measured as of the date of, such transaction or
event divided by (2) the number of Ordinary Shares outstanding on the date of the relevant event after giving effect to such purchase, redemption or acquisition. Such adjustment shall be made
whenever such Ordinary Shares or convertible or exchangeable securities are purchased, redeemed or acquired, and shall become effective immediately after the purchase, redemption or acquisition of
such securities. 

        (d)   In
case the Company shall issue or sell any Ordinary Shares at a price per share below the Greater Price on the date the Company commits or agrees to such sale or
issuance, then the Conversion Price in effect immediately prior thereto shall be adjusted so that the Conversion Price shall be equal to the price determined by multiplying (A) the Conversion
Price at which Debentures were theretofore convertible by (B) a fraction of which (x) the denominator shall be the sum of (1) the number of Ordinary Shares outstanding on the date
of issuance or sale of such Ordinary Shares and (2) the number of additional Ordinary Shares issued or sold, and (y) the numerator shall be the sum of (1) the number of Ordinary
Shares outstanding on the date of issuance or sale of such Ordinary Shares and (2) the number of additional Ordinary Shares which the aggregate offering price of the number of Ordinary Shares
so sold or issued would purchase at the Greater Price on the date the Company commits or agrees to such sale or issuance. Such adjustment shall be made whenever Ordinary Shares are issued or sold, and
shall become effective immediately after the issuance or sale of such securities. 

        (e)   The
Company may make such reductions in the Conversion Price, in addition to those required by paragraphs (a), (b), (c) and (d) of this Section 8.5,
as it considers to be advisable in order that any event treated for United States federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients or any of
their direct or indirect shareholders, members or partners. 

        (f)    For
the purposes of this Section 8.5, the number of Ordinary Shares outstanding at any time shall not include shares held in the treasury of the Company. The
Company shall not pay any dividend or make any distribution on Ordinary Shares held in the treasury of the Company, and shall not issue any rights or warrants in respect of Ordinary Shares held in the
treasury of the Company.

        (b)   the
Company shall authorize the granting to the holders of its Ordinary Shares of rights or warrants to subscribe for or purchase any shares of capital stock of any

is expected that holders of Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for securities, cash or other property deliverable upon such reclassification, consolidation,
merger, sale, transfer, lease conveyance, distribution or Liquidation. Notwithstanding the foregoing, the failure to provide or receive such notice or any defect therein or in the delivery thereof
shall not affect the validity of any action taken in connection with any of the matters described in clauses (a) through (d) above. 

	8.8
	COMPANY
TO RESERVE COMMON STOCK. 

        The
Company shall at all times reserve and keep available, free from pre-emptive rights, out of its authorized but unissued Ordinary Shares, for the purpose of effecting the
conversion of Debentures, the full number of Ordinary Shares then issuable upon the conversion of all outstanding Debentures. 

	8.9
	TAXES
ON CONVERSIONS. 

        The
Company will pay any and all transfer or stamp taxes that may be payable in respect of the issue or delivery of Ordinary Shares on conversion of Debentures pursuant hereto. The
Company shall not, however, be required to pay any income tax payable with respect to conversion of Debentures or any tax which may be payable in respect of any transfer involved in the issue and
delivery of Ordinary Shares in a name other than that of the holder of the Debenture or Debentures to be converted, and no such issue or delivery shall be made unless and until the Person requesting
such issue has paid to 

8

 

the
Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid. 

	8.10
	COVENANT
AS TO ORDINARY SHARES. 

        The
Company covenants that all Ordinary Shares which may be issued upon conversion of Debentures will upon issuance, be fully paid and nonassessable and, except as provided in

	8.12
	PROVISIONS
IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS. 

        In
case of any consolidation of the Company with or merger of the Company into any other Person, any merger of another Person into the Company (other than a merger which does not result
in any reclassification, conversion, exchange or cancellation of outstanding Ordinary Shares), or any sale, transfer, lease, conveyance or other distribution of all or substantially all of the assets
of the Company, the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver a supplement to this Agreement
providing that the holder of each Debenture shall have the right thereafter to convert such Debenture at any time, in whole or in part, into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, sale, transfer, lease, conveyance or other distribution by a holder of the number of Ordinary Shares (including fractional shares) of the Company into which
such Debenture would
otherwise then be convertible (had such conversion taken place immediately prior to such consolidation, merger, sale, transfer, lease, conveyance or other distribution), assuming such holder of
Ordinary Shares (i) is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale, transfer, lease, conveyance or
other distribution was made, as the case may be ("constituent Person"), or an Affiliate of a constituent Person (to the extent that any such Persons are
treated differently than the other holders of Company securities in such transaction) and (ii) failed to exercise his rights of election, if any, as to the kind or amount of securities, cash
and other property receivable upon such consolidation, merger, sale, transfer, lease, conveyance or other distribution (provided that if the kind or
amount of securities, cash and other property receivable upon such consolidation, merger, sale, transfer, lease, conveyance or other distribution is not the same for each Ordinary Share held
immediately prior to such consolidation, merger, sale, transfer, lease, conveyance or other distribution by others than a constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("non-electing share"), then for the purpose of this Section the kind and amount of securities,
cash and other property receivable upon such consolidation, merger, sale, transfer, lease, conveyance or other distribution by each non-electing share shall be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares). Such supplement to this Agreement shall provide for adjustments which, for events subsequent to the effective
date of the event which triggers the requirement of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 8. The above
provisions of this Section 8.12 shall similarly apply to successive consolidations, mergers, sales, transfers, leases, conveyances or other distributions. 

 
 

9.     AFFIRMATIVE COVENANTS.         

	9.1
	MAINTENANCE
OF EXISTENCE. 

        The
Company covenants that so long as any of the Debentures are outstanding, except as provided in Section 10.1, the Company will at all times preserve and keep in full force and
effect its existence under applicable law. Subject to Section 10.1, the Company will at all times preserve and keep in full force and effect the existence of each of its Subsidiaries under
applicable law (unless merged or consolidated into the Company or a Subsidiary) and all rights and franchises of the Company and its 

9

 

Subsidiaries
unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise would not,
individually or in the aggregate, have a Material Adverse Effect. 

	9.2
	DEBENTURES
SUBORDINATE TO SENIOR OBLIGATIONS. 

        The
Company covenants and agrees, and each holder of a Debenture, by acceptance thereof, likewise covenants and agrees, (i) that, to the extent and in the manner set forth in this
Section 9.2, the Company's Senior Obligations, if any, will be senior in right of payment to the Debentures, and (ii) that the subordination provisions set forth in this
Section 9.2 are, and are intended to be, an inducement and a consideration to each holder of any Senior Obligation, whether such Senior Obligation was created or acquired before or after the
date of this Agreement, to acquire and continue to hold, or to continue to hold, such Senior Obligation and such holder of Senior Obligations shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or continuing to hold, such Senior Obligations. 

        (a)   As
used herein, "senior in right of payment to the Debentures" means that: (i) no part of the Debt shall have any
claim to the assets of the Company on a parity with or prior to the claim of the Senior Obligations; and (ii) unless and until the Senior Obligations then due and payable have been paid in
full, without the express prior written consent of all holders of such Senior Obligations, no Holder will take, demand (including by means of any legal action) or receive from the Company, and the
Company will not make, give or permit, directly or indirectly, by set-off, redemption, purchase or in any other manner, any payment of or security for the whole or any part of the Debt;  provided,
however, that (x) at any time, the Company may make, and the Holders may receive,
scheduled payments on account of the Debt in accordance with the terms hereof, except (I) if a default in the performance or observance of any term or condition relating to any Senior
Obligations (other than a default in the payment of any principal of, premium if any, or interest on the Senior Obligations) has occurred and is continuing that permits the holders of the Senior
Obligations to declare such Senior Obligations to be due and payable, the holders of Senior Obligations may give notice (a "Senior Blockage Notice") to
the Company (provided, however, no more than one Senior Blockage Notice may be given during any 365
consecutive day period) that until all Senior Obligations are paid in full, no scheduled payments may be made by the Company on account of the Debt during the period ("Senior
Blockage Period") commencing on the date of such Senior Blockage Notice and ending on the earliest of: (A) 180 days after the date of such Senior Blockage Notice;
(B) the date such default is cured or waived; and (C) the date that the holders of the Senior Obligations shall have given notice to the Company of termination of the Senior Blockage
Period, and (II) when a default in the payment of any principal of, premium if any, or interest on the Senior Obligations has occurred and is continuing or would result therefrom,
(y) upon the acceleration of the maturity of any Senior Obligations, the Holders may accelerate the scheduled maturities of the Debentures if and to the extent permitted hereby at such time but
such acceleration shall not give any Holder any right to take, demand (including by means of any legal action) or receive from the Company, or the Company the right to make, give or permit, directly
or indirectly, by set-off, redemption, purchase or in any other manner, any payment of or security for the whole or any part of the Debentures unless and until the Senior Obligations have
been paid in full, and (z) nothing contained herein shall restrict the right of holders of Debentures to receive interest payments in accordance with Section 6 in respect of dividends or
distributions on Ordinary Shares, or to convert the Debentures in accordance with Section 8. 

        (b)   Any
payment or distribution of assets of the Company, whether in cash, property or securities, to which any Holder would be entitled except for the provisions hereof,
shall be paid or delivered by the Holder, or any receiver, trustee in bankruptcy, liquidating trustee, disbursing agent or other Person making such payment or distribution, to the holders of the
Senior Obligations or their representative, ratably in accordance with the amounts thereof, to the extent necessary to pay in full all Senior Obligations, before any payment or distribution shall be
made to any Holder. 

10

 

        (c)   The
expressions "prior payment in full," "payment in full,"
"paid in full" and any other similar terms or phrases when used herein with respect to the Senior Obligations shall mean the payment in full in cash, in
immediately available funds, of all of the Senior Obligations; and the expression "any payment of or security for the whole or any part of the Debt" and
any other similar terms or phrases when used herein shall not be deemed to include a payment or distribution of shares or other securities of the Company provided for by a plan of reorganization or
readjustment authorized by an order or decree of a court of competent jurisdiction in a reorganization proceeding under any applicable bankruptcy law or of any other corporation provided for by such
plan of reorganization or readjustment, which stock or securities are subordinated in right of payment to all then outstanding Senior Obligations to substantially the same extent as the Debentures are
so subordinated as provided in this Section 9.2. The consolidation of the Company with, or the merger of the Company into, another Person or a Liquidation of the Company following the sale,
transfer, lease, conveyance or other distribution of all or substantially all of the properties and assets of the Company substantially as an entirety to another Person upon the terms and conditions
set forth in Section 10.1 shall not be deemed a "proceeding" for the purposes of this Section 9.2 if the Person formed by such
consolidation or into which the Company is merged or the Person which acquires by sale, transfer, lease, conveyance or other distribution such properties and assets substantially as an entirety, as
the case may be, shall, as a part of such consolidation, merger, conveyance, transfer, lease or other disposition, comply with the conditions set forth in Section 10.1. 

        (d)   If
any payment or distribution, whether consisting of money, property or securities, is collected or received by any Holder in respect of the Debt, except payments
permitted hereunder, such Holder forthwith shall deliver the same to the holders of the Senior Obligations or their representative, ratably in accordance with the amounts thereof, in the form
received, duly endorsed to such holders or representative, if required, to be applied to the payment or prepayment of the Senior Obligations until the Senior Obligations are paid in full. Until so
delivered, such payment or distribution shall be held in trust by such Holder as the property of such holders of Senior Obligations, segregated from other funds and property held by the Holder. 

        (e)   As
used herein, "Senior Obligations" shall mean collectively the unpaid principal of, premium, if any, and interest on
(including, without limitation, interest accruing after the maturity date of any Senior Obligation and interest accruing after the filing of any petition in bankruptcy, or the commencement of any
insolvency, reorganization or like proceeding, relating to the Company, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) all
Indebtedness of the Company whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter incurred, in each case whether on account of principal, premium,
interest, reimbursement obligations, fees, indemnities, costs, expenses or otherwise. 

        (f)    As
used herein, "Debt" shall mean collectively the unpaid principal of, premium, if any, and interest on (including,
without limitation, interest accruing after the maturity date of any Debenture and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency,
reorganization or like proceeding, relating to the Company, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) the Debentures,
whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter incurred, in each case whether on account of principal, premium, interest, reimbursement
obligations, fees, indemnities, costs, expenses or otherwise. 

	9.3
	TREATMENT
UNDER NETHERLANDS TAX LAWS. 

        Holder
and the Company agree that the Debentures qualify as equity for Netherlands tax purposes and further agree that if the treatment of the Debentures is relevant in connection with
(i) any Netherlands corporate income tax, capital tax or other tax return filed by the Company, the Holder or any of their respective affiliates or (ii) any other substantive
communication between the Company, the Holder or any of their respective affiliates, on the one hand, and the Netherlands tax authorities, on 

11

 

the
other hand, the Company, Holder or such affiliate, as applicable, shall treat the Debentures as equity, in accordance with the substantive economics of the Debentures, for Netherlands tax
purposes, to the fullest extent permitted by applicable law. 

 
 

10.   NEGATIVE COVENANTS.         

        The
Company covenants that so long as any of the Debentures are outstanding: 

	10.1
	MERGER,
CONSOLIDATION, ETC. 

        The
Company shall not consolidate with or merge with any other company or convey, transfer or lease or otherwise dispose of all or substantially all of its assets in a single transaction
or series of transactions to any Person unless: 

        (a)   the
successor formed by such consolidation or the survivor of such merger or the Person that acquires by conveyance, transfer or lease substantially all of the assets of
the Company as an entirety, as the case may be, shall be a solvent company organized and existing under the laws of the United States, any State thereof (including the District of Columbia), or the
Netherlands, and, if the Company is not the successor company, such company shall have executed and delivered to each holder of any Debentures its assumption of the due and punctual performance and
observance of each covenant and condition of this Agreement and the Debentures; and 

        (b)   immediately
after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing. 

        No
such conveyance, transfer, or other disposition of all or substantially all of the assets of the Company shall have the effect of releasing the Company or any successor company that
shall theretofore have become such in the manner prescribed in this Section 10.1 from its liability under this Agreement or the Debentures. 

	10.2
	FORBEARANCE
FROM RESTRICTIONS ON RIGHTS OF HOLDERS OF DEBENTURES. 

        The
Company will not enter into any agreement or instrument or otherwise agree to any covenant that would in any way limit the right of the holders of the Debentures to convert the
Debentures into Ordinary Shares. 

 
 

11.   PAYMENTS ON LIQUIDATION.         

        Upon
a Liquidation, the holders of outstanding Debentures shall be entitled to receive, from what remains of the Company's assets after payment of Indebtedness and in preference to and
in priority over the holders of Ordinary Shares and any other outstanding issues of capital stock of the Company (other than any issue of Preferred Shares of the Company that, according to its terms
and conditions, ranks pari passu with the Debentures), an amount per outstanding Debenture equal to the sum of (a) the greater of (i) the
sum of (x) the principal amount outstanding under such Debenture and (y) the Premium on such Debenture as of the date of such Liquidation, and (ii) such amount as would be payable
as a liquidating distribution in respect of the number of Ordinary Shares into which such Debenture was convertible into immediately prior to such Liquidation if such shares were so converted at the
Conversion Price in effect on the date immediately prior to such Liquidation (the greater of the amounts set forth in clauses (i) and (ii) above, the "Liquidation
Payment") and (b) any accrued and unpaid interest payable in accordance with Section 6 in respect of dividends or distributions on Ordinary Shares having a
payment date on or prior to the date of such Liquidation. After the Liquidation Payment and such accrued and unpaid interest has been paid in full to the holders of Debentures (and any class of
Preferred Shares of the Company that, according to its terms and conditions, ranks pari passu with the Debentures), the remainder of the assets of the
Company available for distribution to shareholders may be paid to the holders of Ordinary Shares and other 

12

 

outstanding
shares of capital stock of the Company in proportion to the aggregate nominal amount of such securities. If the assets of the Company are not sufficient to pay the Liquidation Payment in
full to the holders of outstanding Debentures, the holders of all outstanding Debentures shall share ratably in any such distribution. 

 
 

12.   EVENTS OF DEFAULT.         

        An
"Event of Default" shall exist if any of the following conditions or events shall occur and be continuing: 

        (a)   the

(b) and (c) of this Section 12) and such default is not remedied within 30 days after the earlier of (i) a Responsible Officer obtaining actual knowledge of such
default and (ii) the Company receiving written notice of such default from any holder of a Debenture (any such written notice to be identified as a "notice of default" and to refer specifically
to this paragraph (d) of Section 12); or any representation or warranty made in writing by or on behalf of the Company or by any officer of the Company in this Agreement or in any
writing furnished in connection with the transactions contemplated hereby proves to have been false or incorrect in any material respect on the date as of which made; (f) the Company
(i) files, or consents by answer or otherwise to the filing against it of, a petition for relief or reorganization or arrangement or any other petition in bankruptcy, for liquidation or to take
advantage of any bankruptcy, insolvency, reorganization, moratorium or other similar law of any jurisdiction, (ii) makes an assignment for the benefit of its creditors, (iii) consents to

substantial part of its property, or constituting an order for relief or approving a petition for relief or reorganization or any other petition in bankruptcy or for liquidation or to take advantage
of any bankruptcy or insolvency law of any jurisdiction, or ordering the liquidation of the Company or any of its significant subsidiaries, or any such petition shall be filed against the Company or
any of its significant subsidiaries and such petition shall not be dismissed within 60 days. 

 
 

13.   REMEDIES ON DEFAULT.         

	13.1
	ACCELERATION.

        Subject
to Section 9.2: 

        (a)   If
an Event of Default with respect to the Company described in paragraph (f) or (g) of Section 12 has occurred, all the Debentures then outstanding
shall automatically become immediately due and payable. 

        (b)   If
any other Event of Default has occurred and is continuing, any holder or holders of more than 50% in principal amount of the Debentures at the time outstanding may at
any time at its or their option, by notice or notices to the Company, declare all the Debentures then outstanding to be immediately due and payable. 

        (c)   If
any Event of Default described in paragraph (a) or (b) of Section 12 has occurred and is continuing, any holder or holders of Debentures at the
time outstanding affected by such Event of 

13

 

Default
may at any time, at its or their option, by notice or notices to the Company, declare all the Debentures held by it or them to be immediately due and payable. 

        Upon
any Debentures becoming due and payable under this Section 13.1, whether automatically or by declaration, such Debentures will forthwith mature and the entire unpaid
principal amount of such Debentures, plus all accrued and unpaid interest thereon payable in accordance with Section 6 shall all be immediately due and payable, in each and every case without
presentment, demand, protest or further notice, all of which are hereby waived. From and after the time at which the Debentures become due and payable in accordance with this Section 13.1, the
full amount due and payable thereunder shall accrue interest at the Default Rate. 

	13.2
	OTHER
REMEDIES. 

        If
any Default or Event of Default has occurred and is continuing, and irrespective of whether any Debentures have become or have been declared immediately due and payable under
Section 13.1, the holders of 50% or more in principal amount of the Debentures then outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity
or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Debenture, or for an injunction against a violation of any of the terms hereof or
thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 

        Notwithstanding
the foregoing, the holder of any Debenture shall have the right, which is absolute and unconditional, to receive payment of the principal of, premium, if any, and
interest on such Debenture and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such holder. 

	13.3
	RESCISSION.

        At
any time after any Debentures have been declared due and payable pursuant to clause (b) of Section 13.1, the holders of not less than 25% in principal amount of the
Debentures then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the
Debentures, all principal of and premium, if any, on any Debentures that are due and payable other than by reason of such declaration and are unpaid, and all interest on such overdue principal and (to
the extent permitted by applicable law) any overdue interest in respect of the Debentures, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of
amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 18, and (c) no judgment or decree has been entered for the
payment of any monies due pursuant hereto or to the Debentures. No rescission and annulment under this Section 13.3 will extend to or affect any subsequent Event of Default or Default or impair
any right consequent thereon. 

	13.4
	NO
WAIVERS OR ELECTION OF REMEDIES, EXPENSES, ETC. 

        No
course of dealing and no delay on the part of any holder of any Debenture in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such
holder's rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Debenture upon any holder thereof shall be exclusive of any other right, power or remedy referred
to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 16, the Company will pay to the
holder of each Debenture on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 13,
including, without limitation, reasonable attorneys' fees, expenses and disbursements.

14.   REGISTRATION; EXCHANGE; SUBSTITUTION OF DEBENTURES.         

	14.1
	REGISTRATION
OF DEBENTURES. 

        The
Company shall keep at its principal executive office a register for the registration and registration of transfers of Debentures (the "Debenture
Register"). The name and address of each holder of one or more Debentures, each transfer thereof and the name and address of each transferee of one or more Debentures shall be
registered in such Debenture Register. The Company shall keep the Debenture Register together with its shareholder register, and shall include a note in its shareholder register to the effect that
certain Ordinary Shares listed therein are stapled to Debentures as set forth in the Debenture Register. Prior to due presentment for registration of transfer, the Person in whose name any Debenture
shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company
shall give to any holder of at least US $15,000,000.00 aggregate principal amount of Debentures (which amount shall be reduced pro rata in the case of partial Redemptions or conversions), promptly
upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Debentures. 

	14.2
	TRANSFER
AND EXCHANGE OF DEBENTURES. 

        Subject
to Section 14.4, upon surrender of any Debenture at the principal executive office of the Company for registration of transfer or exchange (and in the case of a surrender
for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of such Debenture or his attorney duly authorized in writing and
accompanied by the address for notices of each transferee of such Debenture or part thereof), the Company shall execute and deliver, at the Company's expense (except as provided below), one or more
new Debentures (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Debenture. Each such new Debenture
shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Debenture shall be dated and bear interest from the date to which
interest shall have been paid on the surrendered Debenture or dated the date of the surrendered Debenture if no interest shall have
been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Debentures. Debentures shall not be
transferred in denominations of less than US $1,000.00. Any transferee, by its acceptance of a Debenture registered in its name (or the name of its nominee), shall be deemed to have made the
representation set forth in Section 4.3. 

	14.3
	REPLACEMENT
OF DEBENTURES. 

        Upon
receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Debenture, and (a) in the case of
loss, theft or destruction, of indemnity reasonably satisfactory to it, or (b) in the case of mutilation, upon surrender and cancellation thereof, the Company at its own expense shall execute
and deliver, in lieu thereof, a new Debenture, dated the date hereof, in replacement of such Debenture. 

	14.4
	DEBENTURES
STAPLED TO ORDINARY SHARES. 

        The
Debenture Register shall include, for each Debenture listed therein, the identification numbers (as such appears in the Company's shareholder register) of the Stapled Shares stapled
to such Debenture. Notwithstanding anything contained herein to the contrary, a holder may not Transfer any Debenture (or portion thereof) unless such holder simultaneously Transfers to the transferee
thereof one whole Ordinary Share for each US $1,000.00 aggregate principal amount of Debentures; provided that this sentence shall not apply to
(i) the redemption of any Debenture pursuant to Section 7, (ii) the Transfer of any Debenture to an Affiliate of such holder or to the Company, or (iii) the exchange of any
Debenture or Debentures solely for a Debenture or Debentures representing different principal 

15

 

amounts.
Any Transfer of Debenture without a Transfer of the corresponding Stapled Share or Stapled Shares, to the same person as such Debenture is Transferred to, shall be invalid and void and shall
not be binding on the Company. Upon any Transfer of Ordinary Shares held by a holder of Debentures, such holder shall be deemed to have simultaneously Transferred, to the same transferee as such
Ordinary Shares have been transferred to, a portion of the Debentures held by such holder as shall equal the principal amount of Debentures to which such Ordinary Shares would be considered Stapled
Shares. The ratio of one whole Ordinary Share per US $1,000.00 aggregate principal amount of Debentures shall be adjusted proportionately to reflect partial Redemptions, and any reclassification of,
or adjustment to the number of outstanding, Ordinary Shares, or any repurchase, redemption or other similar transaction relating to the outstanding Ordinary Shares. 

 
 

15.   PAYMENTS ON DEBENTURES.         

        Unless
otherwise agreed between the Company and Holder, payments of principal and interest becoming due and payable on the Debentures shall be made United States dollars in Amsterdam,
the Netherlands, at the principal office of the Company. The Company may at any time, by notice to each holder of a Debenture, change the place of payment of the Debentures so long as such place of
payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction. 

 
 

16.   EXPENSES, ETC.         

	16.1
	TRANSACTION
EXPENSES. 

        The
Company will pay all reasonable out-of-pocket fees and expenses in connection with this Agreement or the Debentures, including, without limitation:
(a) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement or the Debentures or in responding to any
subpoena or other legal process or informal investigative demand issued in connection with this Agreement or the Debentures, or by reason of being a holder of any Debenture, and (b) the costs
and expenses, including financial advisors' fees, incurred in connection with the insolvency or bankruptcy of the Company or any Subsidiary or in connection with any work-out or
restructuring of the transactions contemplated hereby and by the Debentures. The Company will pay, and will save Holder and each other holder of a Debenture harmless from, all claims in respect of any
fees, costs or expenses if any, of brokers and finders or professional advisors. 

	16.2
	SURVIVAL.

        The
obligations of the Company under this Section 16 will survive the payment or transfer of any Debenture, the enforcement, amendment or waiver of any provision of this Agreement
or the Debentures, and the termination of this Agreement. 

 
 

17.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.         

        All
representations and warranties contained herein shall survive the execution and delivery of this Agreement and the Debentures, the purchase or transfer by Holder of any Debenture or
portion thereof or interest therein and the payment of any Debenture, and may be relied upon by any subsequent holder of a Debenture, regardless of any investigation made at any time by or on behalf
of Holder or any other holder of a Debenture. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be deemed
representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement and the Debentures embody the entire agreement and understanding between Holder
and the Company, and supersede all prior agreements and understandings, relating to the subject matter hereof. 

16

 

 
 

18.   AMENDMENT AND WAIVER.         

	18.1
	REQUIREMENTS.

        This
Agreement and the Debentures may be amended, and the observance of any term hereof or of the Debentures may be waived (either retroactively or prospectively), with (and only with)
the written consent of the Company and the Required Holders, except that no such amendment or waiver may, without the written consent of the holder of each Debenture at the time outstanding affected
thereby, (i) subject to the provisions of Section 13 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or
change the time of payment or method of computation of interest on, the Debentures, (ii) change the percentage of the principal amount of the Debentures the holders of which are required to
consent to any such amendment or waiver, or (iii) amend any of Sections 6, 7, 8, 12(a), 12(b), 13 or this Section 18. 

	18.2
	SOLICITATION
OF HOLDERS OF DEBENTURES. 

        (a)   Solicitation. The Company will provide each holder of the Debentures (irrespective of the amount of Debentures then owned
by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed
amendment, waiver or consent in respect of any of the provisions hereof or of the Debentures. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected
pursuant to the provisions of this Section 18 to each holder of outstanding Debentures promptly following the date on which it is executed and delivered by, or receives the consent or approval
of, the requisite holders of Debentures. 

        (b)   Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, or grant any security, to any holder of Debentures as consideration for or as an inducement to the entering into by any holder of Debentures of
any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each holder of
Debentures then outstanding that consents thereto. 

	18.3
	BINDING
EFFECT, ETC. 

        Any
amendment or waiver consented to as provided in this Section 18 applies equally to all holders of Debentures and is binding upon them and upon each future holder of any
Debenture and upon the Company without regard to whether such Debenture has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation,
covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Debenture nor
any delay in exercising any rights hereunder or under any Debenture shall operate as a waiver of any rights of any holder of such Debenture. 

	18.4
	DEBENTURES
HELD BY COMPANY, ETC. 

        Solely
for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Debentures then outstanding approved or consented to any
amendment, waiver or consent to be given under this Agreement or the Debentures, or have directed the taking of any action provided herein or in the Debentures to be taken upon the direction of the
holders of a specified percentage of the aggregate principal amount of Debentures then outstanding, Debentures directly or indirectly owned by the Company or any of its controlled Affiliates shall be
deemed not to be outstanding.
