Anti-Dilution and Other Provisions. 6.1 Reset of Conversion Price. (a) If the Average Bid Price for the 15 Trading Days immediately preceding May 1, 1999 is less than the Conversion Price then in effect, then the Conversion Price for $7,500,000 of the Notes shall be reset downward on May 1, 1999 to a Conversion Price equal to such Average Bid Price. If the Average Bid Price for the 15 Trading Days immediately preceding April 1, 2000 is less than the Conversion Price then in effect, then the Conversion Price for $7,500,000 of the Notes shall be reset downward on April 1, 2000 to a Conversion Price equal to such Average Bid Price. If the Conversion Price is reset on April 1, 2000, and, as a result of the reset on May 1, 1999, some of the Notes are convertible at a Conversion Price higher than the Conversion Price of other Notes, the Conversion Price of the Notes with the higher Conversion Price shall be reset first and then the Conversion Price of the Notes with the lower Conversion Price shall be reset, until the Conversion Price of $7,500,000 of the Notes shall have been reset. If pursuant to this Section 6.1(a) the Conversion Price is reset with respect to less than all of the outstanding Notes, then the Conversion Price for this Note shall be reduced with respect to that portion of the principal amount of this Note equal to the principal amount of this Note times a fraction of which the numerator is $7,500,000 and the denominator is the aggregate - 10 - 11 principal amount of the Notes outstanding; provided, however, that if pursuant to this Section 6.1(a) the Conversion Price is reset on May 1, 1999 and reset again on April 1, 2000 with respect to less than all of the Notes with a lower Conversion Price, then the Conversion Price for such Notes shall be reduced with respect to that portion of each such Note equal to the principal amount of that Note times a fraction of which the numerator is the remainder of the $7,500,000 principal amount of Notes to be reset (after the Conversion Price of the Notes with the higher Conversion Price has been reset) and the denominator is the aggregate principal amount of the Notes with the lower Conversion Price. In each such event, the Company shall issue and deliver to the Holder two new Notes in exchange for this Note, each bearing the date of original issue and having the same rights and privileges as this Note, one in the principal amount for which the Conversion Price is not changing reflecting the Conversion Price prior to the reset pursuant to this Section 6.1(a) and the other in the principal amount for which the Conversion Price is changing and reflecting the reset Conversion Price. (b) If after the later of the date hereof or the last date on which the Conversion Price had been reset pursuant to this Section 6.1, (1) the Company shall issue more than 12 million shares of the Company's Common Stock (excluding shares issued pursuant to this Note but including shares issuable upon exercise or conversion of any rights, options, warrants or convertible or exchangeable securities referred to in clause (2) below), or (2) the Company shall issue rights, options or warrants to purchase, or securities convertible or exchangeable into, an aggregate of more than 12 million shares of the Company's Common Stock, then on the 210th day after the last such issuance which resulted in the aggregate exceeding 12 million shares, if the Average Bid Price for the 15 Trading Days immediately preceding such day is less than the Conversion Price as then in effect, then the Conversion Price shall be reset to equal such Average Bid Price. (c) If after the date hereof there is a reverse stock split of shares of the Company's Common Stock into a lesser number of shares, then on the 90th day after such split, if the Average Bid Price for the 15 Trading Days immediately preceding such day is less than the Conversion Price as then in effect, then the Conversion Price shall be reset to equal such Average Bid Price. (d) Notwithstanding anything to the contrary in this Note, the Company may elect, by notice to the Holders of the Notes (the "Issuer's Election") given on or before any date on which the Conversion Price would be reset pursuant to this Section 6.1, to set on such reset date the Conversion Price instead at the lower of $.50 per share (subject to reduction pursuant to the anti-dilution provisions of Section 6.2 hereof) or the lowest price at which any shares of the Company's Common Stock were issued after the date hereof. - 11 - 12 6.2 Adjustment of Conversion Price.

Such adjustment shall become effective on the date of such issue or grant or distribution. (v) If and whenever the Company or (at the direction or request of or pursuant to any arrangements with the Company or any subsidiary) any subsidiary or any other company, Person or entity (otherwise than as mentioned in paragraph (iii) or (iv) of this Section 6.2(b)) shall issue or grant wholly for cash or for no consideration any securities (other than the Notes but including options, warrants and other rights) carrying rights of conversion into, or exchange or subscription for, Shares, or securities which by their terms might be redesignated as Shares or so as to carry rights of conversion into, or exchange or subscription for, Shares, where the consideration per Share receivable upon exercise of such rights or upon such redesignation is less than the Current Market Price per Share on the dealing day last - 15 - 16 preceding the date on which the terms of such issue or grant are publicly announced, the Conversion Price shall be adjusted by multiplying the Conversion Price in force immediately before such issue or grant by the following fraction: A + B ------ A + C where: A is the number of Shares in issue immediately before such issue or grant; B is the number of Shares which the aggregate consideration receivable for the maximum number of Shares to be issued upon exercise in full of such rights, or arising from such redesignation, would purchase at such Current Market Price per Share; and C is the maximum number of Shares to be issued upon exercise in full of such rights at the initial conversion, exchange or subscription price or rate or to arise upon such redesignation. Such adjustment shall become effective on the date of such issue or grant. (vi) If the Company (after consultation with a Majority of the Holders) or a Majority of the Holders (after consultation with the Company) determines that an adjustment should be made to the Conversion Price as a result of one or more events or circumstances not referred to in paragraphs (i) to (v) of this Section 6.2(b) (even if the relevant event or circumstance is specifically excluded from the operation of those paragraphs or any of them) the Company, shall, at its own expense and acting reasonably, request the Auditors, acting as experts, to determine as soon as practicable what adjustment (if any) to the Conversion Price is fair and reasonable to take - 16 - 17 account of such event or circumstance and the date on which such adjustment should take effect, and upon such determination such adjustment (if any) shall be made and shall take effect in accordance with such determination, but so that an adjustment shall be made pursuant to this sub-paragraph (vi) if the Auditors are so requested to make such a determination not more than 21 days after the occurrence of the relevant event or circumstance. Provided that where the circumstances giving rise to any adjustment pursuant to this Section 6.2(b) have already resulted or will result in an adjustment to the Conversion Price or where the circumstances giving rise to any adjustment arise by virtue of any other circumstances which have already given or will give rise to an adjustment to the Conversion Price, such modification (if any) shall be made to the operation of the provisions of this Section 6.2(b) as may be advised by the Auditors, acting as experts, to be in their opinion appropriate in order to give the intended effect. (c) Calculation of Consideration Receivable. For the purpose of any calculation of the consideration receivable pursuant to Section 6.2(b) the following provisions shall apply: (i) the aggregate consideration receivable for Shares issued for cash shall be the amount of such cash received or receivable by the Company, provided that in no case shall any deduction be made for any commission or any expenses paid or incurred by the Company for any underwriting of the issue or otherwise in connection therewith; (ii) the aggregate consideration receivable for Shares to be issued upon the exercise of rights of exchange or subscription shall be the consideration received or receivable by the Company which is attributed by the Company to such rights or, if no part of such consideration is so attributed or the Majority of the Holders so requires by notice in writing to the Company, the fair market value of such rights as at the date on - 17 - 18 which the terms of issue of the relevant securities (including options, warrants and other rights) are publicly announced (as determined in good faith by an investment banking firm of national repute, acting as an expert, appointed by the Company and approved in writing by a Majority of the Holders or, in default of such appointment or in the absence of such approval, appointed by a Majority of the Holders) plus the additional consideration to be received by the Company as a consequence of such exercise, such additional consideration to be the amount (including any premium) to be treated by the Company as paid up on the Shares or other securities arising from such exercise (the consideration in all such cases to be determined subject to the proviso in paragraph (i) of this Section 6.2(c)); (iii) the consideration per Share receivable upon the exercise of rights, exchange or subscription shall be the aggregate consideration referred to in paragraph (ii) of this Section 6.2(c), converted into dollars if such consideration is expressed in a currency other than dollars at such rate of exchange as may be determined in good faith by an investment banking firm of national repute, acting as an expert, appointed by the Company and approved in writing by a Majority of the Holders or, in default of such appointment or in the absence of such approval, appointed by a Majority of the Holders, to be the spot rate ruling at the close of business on the date on which the terms of issue of the relevant securities (including options, warrants and other rights) are publicly announced, divided by the number of Shares to be issued upon such exercise at the initial conversion, exchange or subscription price or rate; and (iv) if the consideration receivable for Shares or upon the exercise of rights, exchange or subscription is property other than cash, then the amount of the consideration receivable shall be the fair market - 18 - 19 value of such property as determined in good faith by the chief financial officer of the Company, except that if the market value of the Shares issued exceeds $10,000,000 and a Majority of the Holders dispute the determination by the chief financial officer, then as determined in good faith by an investment banking firm of national repute, acting as an expert, appointed by the Company and approved in writing by a Majority of the Holders; provided, however, that if the Eurobonds are exchanged, the fair market value of the Eurobonds shall be deemed to be the face value of the Eurobonds (regardless of any price at which they may be traded). (d) Post-record date Adjustments. If the Conversion Date in relation to any Note shall be after the record date for any such issue, grant or offer as is mentioned in Section 6.2(b), but before the relevant adjustment becomes effective under Section 6.2(b), the Company shall (conditional upon such adjustment becoming effective) procure that there shall be issued to the converting Holder or in accordance with the instructions contained in the Conversion Notice (subject to any applicable exchange control or other laws or other regulations) such additional number of Shares as, together with the Shares issued or to be issued on conversion of the relevant Note, is equal to the number of Shares which would have been required to be issued on conversion of such Note if the relevant adjustment (more particularly referred to in such paragraphs) to the Conversion Price had in fact been made and become effective immediately after the relevant record date. Such additional Shares will be allotted as at, and within one month after, the relevant Conversion Date or of the date of issue of Shares if the adjustment results from the issue of Shares and certificates for such Shares will be despatched within such period of one month. (e) Other Provisions Relating to Adjustments. The Company may at any time or from time to time reduce the Conversion Price either permanently or temporarily (a "Voluntary Reduction"). Notwithstanding a Voluntary Reduction, the determination of the interest rate payable pursuant to Section 2.1 and the determination of whether a Mandatory Prepayment is due pursuant to Section 1.2 shall be made without giving effect to the Voluntary Reduction. Notwithstanding the provisions of this Section 6.2, the Conversion Price will not be reduced as a result of any adjustment, and the Company covenants not to take any action, if, after giving effect thereto, the Conversion Price would be reduced to such an extent that, under applicable law then in effect, Notes may not be converted at such reduced Conversion Price for legally issued, fully paid and non-assessable Shares. The Conversion Price may also not be reduced so that, on exchange of Notes, Shares would be issued at a - 19 - 20 discount to their par value (the Company hereby agreeing not to take any action to increase the par value of the shares of the Company's Common Stock). No adjustment will be made where such adjustment would be less than 5 percent of the Conversion Price then in effect. Any adjustment not so made will be carried forward and taken into account in any subsequent adjustment. On any adjustment, the resultant Conversion Price, if not an integral multiple of one cent shall be rounded down to the nearest one cent. Where more than one event which gives or may give rise to an adjustment to the Conversion Price occurs within such a short period of time that in the opinion of the Auditors the foregoing provisions would need to be operated subject to some modification in order to give the intended result, such modification shall be made to the operation of the foregoing provisions as may be advised by the Auditors to be in their opinion appropriate in order to give such intended result. No adjustment will be made to the Conversion Price when Shares or other securities (including rights or options) are issued, offered or granted to employees (including directors holding executive office) of the Company or any subsidiary or any associated company of the Company pursuant to any employee benefit, compensation or profit sharing plan, whether now in effect or hereafter created or amended. 6.3 Covenants Relating to Conversion. (a) The Company hereby undertakes to and covenants with the Holders of the Notes that so long as any Conversion Right remains exercisable, it will, save with the prior written approval of all of the Holders of the Notes: (i) Issue and ensure sufficient share capital: issue Shares to Holders of the Notes on the exercise of Conversion Rights in accordance with the terms of the Notes and at all times keep available for issue free from pre-emptive rights out of its authorized but unissued capital such number of Shares as would enable the Conversion Rights and all other rights of subscription and exchange for and exchange into Shares to be satisfied in full; (ii) Limited modification of rights: not in any way modify the rights attaching to the Shares with respect to voting, dividends or liquidation nor issue any other class of equity share capital - 20 - 21 carrying any rights which are more favorable than the rights attaching to the Shares; (iii) Restricted action: not make any issue, grant or distribution or take any other action if the effect thereof would be that, on the conversion of Notes, Shares would have to be issued at a discount or otherwise could not, under any applicable law then in effect, be legally issued as fully paid; (iv) Officers' certificate on adjustment of Conversion Price: upon the happening of an event as a result of which the Conversion Price will be adjusted pursuant to the Notes, as soon as reasonably practicable deliver to the Holders of the Notes a certificate signed by two duly authorized officers of the Company on behalf of the Company setting forth brief particulars of the event, the adjusted Conversion Price, the date on which such adjustment takes effect and such other particulars and information as the Holders may reasonably require; and (v) Maintain Listing: maintain a listing for all the issued shares of the Company's Common Stock on the New York Stock Exchange, it being understood that if the Company is unable to obtain or maintain such listing of the shares, it will seek to obtain and maintain a listing for all the shares issued on conversion of the Notes on the American Stock Exchange or the NASDAQ National Market System, or if it is unable to obtain a listing thereon, on any other stock exchange or on NASDAQ or on the National Quotation Bureau Incorporated (each an "Alternative Stock Exchange") as the Company may from time to time (with the written consent of a Majority of the Holders which consent shall not be unreasonably withheld and which consent shall be deemed given if not denied within three (3) business days of receipt of a notice requesting consent) determine and will forthwith give notice to the Holders of the listing, de-listing or - 21 - 22 quotation or lack of quotation of the Shares (as a class) by any such Alternative Stock Exchange. 6.4 Adjustment for Consolidations and Mergers. In case of any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving corporation) or the sale of all or substantially all of the assets of the Company to another corporation, this Note thereafter shall be convertible into the kind and amount of shares of stock or other securities or property to which a Holder of the number of shares of the Company's Common Stock issuable upon conversion of this Note would have been entitled upon such consolidation, merger or sale; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors of the Company) shall be made in the application of the provisions in this Section 6, to the end that the provisions set forth in this Section 6 (including provisions with respect to changes in and adjustments of the number of shares of Common Stock into which this Note is convertible) shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other securities or property thereafter deliverable upon the conversion of this Note. 6.5 No Impairment. The Company will not, by amendment of its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in the carrying out of all the provisions of this Section 6 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against impairment. 6.6 Notices to Holder. If at any time, (a) The Company shall take any action which would require an adjustment pursuant to this Section 6 in the Conversion Price or in the number of shares issuable upon conversion of this Note; or (b) The Company shall issue any additional shares of Common Stock or declare any dividend (or any other distribution) on its Common Stock; or (c) there shall be any capital reorganization or reclassification of the Common Stock, or any consolidation or merger to which the Company is a party, or any sale or transfer of all or substantially all of the assets of the Company; or - 22 - 23 (d) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Company; then, in any one or more of such cases, the Company shall give written notice to the Holder, not less than 20 days before any record date or other date set for definitive action, or of the date on which such reorganization, reclassification, sale, consolidation, merger, dissolution, liquidation or winding up shall take place, as the case may be. Such notice shall also set forth such facts as shall indicate the effect of such action (to the extent such effect may be known at the date of such notice) on the current Conversion Price and the kind and amount of shares of the Company's Common Stock and other securities and property deliverable upon conversion of this Note. Such notice shall also specify the date as of which the holders of the Company's Common Stock of record shall be entitled to exchange their shares of the Company's Common Stock for securities or other property deliverable upon such reorganization, reclassification, sale, consolidation, merger, dissolution, liquidation or winding up, as the case may be. 7. Put Upon Merger. In case of any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving corporation) in which the shareholders of the Company receive solely cash for their shares of the Company's Common Stock, the Holder may elect, at its sole option, by notice to the Company given at any time within 30 days after the notice from the Company of the consummation of the consolidation or merger, to require the Company to purchase the Note at a purchase price equal to 100% of the principal amount of the Note, plus all accrued and unpaid interest. If the Holder so elects, a closing shall be held at the principal offices of the Company on a date determined by the Company not later than 30 days after the notice from the Holder; at the closing, the Holder shall surrender the Note to the Company, and the Company shall pay the purchase price for the Note in cash. 8. Covenants by the Company. 8.1 Ranking. The Notes are direct, unconditional and unsecured obligations of the Company and rank, and will rank pari passu, without any preference among themselves, and such obligations will rank senior to all other outstanding and unsecured subordinated obligations of the Company, present and future, but, in the event of bankruptcy or insolvency of the Company, only to the extent permitted by the applicable laws relating to creditors' rights. - 23 - 24 8.2 Additional Guaranty. At such time as the Eurobonds are repaid or converted into shares of the Company's Common Stock so that no Eurobonds are outstanding or if the Eurobonds are refinanced with Junior Debt or on a pari passu basis with the guaranty to be issued by SPMI as referred to below, the Company shall cause SPMI to guaranty the Company's obligations pursuant to the Notes pursuant to a Guaranty in the same form as the Guaranty executed by the Company's other subsidiaries on the date hereof. If the Eurobonds are refinanced on a basis that requires the Guaranty to be issued by SPMI to be subordinated to such refinanced debt, then the Guaranty shall be so subordinated to the refinanced indebtedness. At such time as the Company forms any additional subsidiary, the Company shall cause the subsidiary to guaranty the Company's obligations pursuant to the Notes pursuant to a Guaranty in the same form as the Guaranty executed by the Company's other subsidiaries on the date hereof. 8.3 Additional Debt. Except for Project Debt (as defined in Section 8.3), neither the Company nor any of its subsidiaries shall issue or incur any additional Indebtedness that is secured by any assets of the Company or its subsidiaries unless the Notes are equally secured on a pari passu basis by such assets. As used in this Note, Project Debt means Indebtedness incurred by a subsidiary of the Company expressly to fund the construction or development of a specific project by that subsidiary. 8.4 Federal Tax Matters. The Company shall deduct for Federal income tax purposes the interest payable on the Notes only to the extent of the interest paid or payable on the Notes in cash or shares of the Company's Common Stock pursuant to Sections 2 and 3 hereof. 8.5 Financial Information.
