The number of Shares convertible is determined based on the Convertible Rate as set forth in 1(b) hereof, subject to adjustment as set forth in the Convertible Note. Simultaneously with the execution and delivery of this Agreement, you and the Company have entered into a Registration Rights Agreement, dated as of the date hereof (the "Registration Rights Agreement"), pursuant to which the Company has agreed to register the Convertible Note and the Shares under certain circumstances. All capitalized terms not defined herein shall have the meaning ascribed in the form of the Convertible Note. 1. AGREEMENT TO ISSUE AND ACCEPT. (a) On the basis of the representations and warranties and subject to the terms and conditions set forth herein, the Company agrees to issue to you, and you agree to purchase from the Company, the Option, in consideration of which you agree to make a payment in the amount of $900,000 to the Company, as of the Closing Date, by wire transfer to the Company's account [****]. The closing of the issuance and acceptance of the Option shall take place on the earlier of March 21, 2001 or the third Business Day after the conclusion of the Averaging Period as defined below (the "Closing Date"). (b) The Conversion Rate of the Convertible Note subject to the Option shall be determined in accordance with the following formula: CR = 1000 ---- (AP x 1.7) where CR = the Conversion Rate 1 2 CONFIDENTIAL TREATMENT--EDITED COPY and AP = the average of the best bid price for the Common Stock as of 10:00 a.m., New York City time, as reported by Bloomberg L.P., for each Trading Day (as defined in Annex II hereto) in the Averaging Period. The "Averaging Period" shall mean the period of 15 consecutive Trading Days commencing on February 20, 2001; provided that either the Company or the Purchaser may, by telephone notice to the other party hereto given between 8:45 a.m. and 9:45 a.m., New York City time, on any Trading Day, exclude such Trading Day from the Averaging Period, and the Averaging Period shall be extended one additional Trading Day for each Trading Day so excluded; provided further, that if the Averaging Period has not included 15 Trading Days by March 16, 2001, then the Averaging Period shall nonetheless terminate and be comprised of the Trading Days included up to such date. (c) If the Averaging Period comprises less than 15 Trading Days, then (i) the purchase price of the Option payable by the Purchaser hereunder and (ii) the principal amount of the Convertible Note covered by the Option to be purchased by the Purchaser hereunder shall be reduced to an amount equal to $5,913,044, multiplied by a fraction, the numerator of which shall be the actual number of Trading Days included in the Averaging Period, and the denominator of which shall be 15. 2. EXERCISE OF CALL OPTION. (a) The Purchaser may exercise the Option issued hereunder at any time on or prior to March 21, 2006, by delivering a written notice to the Company (a "Purchaser's Call Option Notice") requiring the Company to issue and sell (in which event the Purchaser shall purchase) the Convertible Note covered by the Option having the principal amount specified in such notice (but not less than $1,000,000 nor in excess of the maximum amount covered by the Option as specified in the applicable terms) and the Conversion Rate specified in the applicable terms but having the maturity date and in all other respects having the terms set forth in the form attached hereto as Annex I (and with the applicable series designation, principal amount and Conversion Rate inserted therein), at a purchase price of 100% of the principal amount thereof. (b) The issuance of the Convertible Note will be effected on the basis of the representations and warranties and subject to the terms and conditions set forth herein, against payment of the above-specified purchase price therefor. The closing of the issuance and acceptance of the Convertible Note against such payment shall take place on such date and time as may be specified in the Purchaser's Call Option Notice but no earlier than three Business Days and no later than twenty Business Days after the date of delivery of the Purchaser's Call Option Notice, at which time the Company shall deliver to the Purchaser the Convertible Note in certificated form against delivery by the Purchaser of a wire transfer of the purchase price to the Company's account [****]. Upon the occurrence of any Change of Control, the Company shall take appropriate action to ensure that the Purchaser shall have the right to exercise the Option after the Change of Control. (c) Subject to the conditions set forth in this Section 2(c), the Company, upon five business days' notice to the Purchaser, may elect, in lieu of delivering the Convertible Note 2 3 CONFIDENTIAL TREATMENT--EDITED COPY pursuant to this Section 2, to deliver the number of shares of Common Stock determined pursuant to the following formula: N = P x CR ---- 1000 where N = the number of shares of Common Stock so deliverable, P = the principal amount of the Convertible Note in lieu of which such shares of Common Stock are delivered; and CR = the Conversion Rate of the Convertible Note in lieu of which such shares of Common Stock are delivered, as set forth in the applicable terms.

Notwithstanding any other provision of this Security, the Company shall, if the holder so elects, deliver any shares of Common Stock issuable pursuant to this Section 2 to any third party designated in writing by the holder. (e) In addition to any other rights available to the Purchaser, if the Company defaults in its obligation to deliver to the Purchaser the Convertible Note (or shares of Common Stock in lieu thereof) required to be delivered to it pursuant to this Section 2, the Company shall pay the Purchaser, upon the Purchaser's demand, as liquidated damages by cash or wire transfer in immediately available funds to the account of the Purchaser, or as otherwise directed by the Purchaser, an amount determined pursuant to the following formula: D = CP - 1000 P x CR ---- ------ CR X 1000 where D = the amount of such liquidated damages; 3 4 CONFIDENTIAL TREATMENT--EDITED COPY CP = 110% of the average Closing Price (as defined in the Convertible Note) on the five Trading Days immediately following such default; CR = the Conversion Rate of the Convertible Note in respect of which the Company defaulted, as set forth in the applicable terms; P = the principal amount of the Convertible Note in respect of which the Company defaulted. 3.

Conversion. (a) The holder of this Security is entitled at any time on or after March 21, 2002 and before the close of business on March 21, 2006 (or, in case the holder hereof has exercised his right to require the Company to repurchase this Security or a portion hereof pursuant to Section 3 hereof, then in respect of this Security or such portion hereof, as the case may be, until and including, but (unless the Company defaults in making the payment due upon repurchase) not after, the close of business on the Repurchase Date) to convert this Security (or any portion of the principal amount hereof that is an integral multiple of $1,000), into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100 of a share) of Common Stock of the Company at the rate of 116.9152 shares of Common Stock for each $1,000 principal amount of Security (or at the current adjusted rate if an adjustment has been made as provided below) (the "Conversion Rate") by surrender of this Security, duly endorsed or assigned to the Company or in blank to the Company at the Designated Office, accompanied by written notice to the Company that the holder hereof elects to convert this Security (or if less than the entire principal amount hereof is to be converted, specifying the portion hereof to be converted). Notwithstanding the foregoing, unless the holder of this Security notifies the Company to the contrary, such holder shall be deemed for all purposes to have converted this Security, subject only to surrender of this Security against delivery of the Shares and cash issuable upon such conversion (which surrender may take place before or after the date of such deemed conversion, without affecting the availability thereof), immediately prior to the close of business on March 21, 2006, if the Closing Price of the Common Stock on the immediately preceding Trading Day exceeds 115% of the Conversion Price. Subject to Section 2(b) below, no payment or adjustment is to be made on conversion for dividends on the Common Stock issued on conversion hereof. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest, the Company shall pay a cash adjustment, computed on the basis of the Closing Price of the Common Stock on the date of conversion, or, at its option, the Company shall round up to the next higher whole share. Notwithstanding any other provision of this Security, the Company shall, if the holder so elects, deliver the shares of Common Stock issuable upon conversion of this Security to any third party designated in writing by the holder. Notwithstanding the foregoing, no holder of this Security that is subject to the restrictions of Section 4 of the Bank Holding Company Act of 1956, as amended (the "BHCA") (a "BHCA Person") shall have the right to convert this Security if, after giving effect to such conversion, the BHCA Person and its affiliates and transferees would own or be deemed to own shares of Common Stock in excess of either the maximum number of shares of Common Stock which the BHCA Person is permitted to own under the BHCA and the regulations of the Board of Governors of the Federal Reserve System thereunder or such lower number as the relevant BHCA Person may have requested in writing to the Company. Any Security held by an assignee or transferee of a holder subject to the restriction on conversion in this paragraph shall continue to be subject to the same restriction on conversion unless such Security was assigned or transferred (i) to the public in an offering registered under the Securities Act, (ii) in a transaction pursuant to Rule 144 or 144A under the Securities Act in which no person acquires Securities convertible into more than 2% of the outstanding Common Stock, (iii) in a single transaction to a third party who acquires a majority of the Common Stock without regard to the conversion of any Security so transferred or, (iv) in any other manner permitted under the BHCA. The Company may rely on the representation of the relevant BHCA Person that a transfer has been made in a manner which permits conversion of such Security. The holder of this Security, by acceptance thereof, shall be deemed to have agreed to the foregoing restriction on transfers. (b) The Conversion Rate shall be subject to adjustments from time to time as follows: (1) In case the Company shall pay or make a dividend or other distribution on any class of capital stock of the Company payable in shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the Determination Date for such dividend or other distribution shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of 3 11 CONFIDENTIAL TREATMENT--EDITED COPY Common Stock outstanding at the close of business on such Determination Date and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such increase to become effective immediately after the opening of business on the day following such Determination Date. For the purposes of this paragraph (1), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company or issuable upon the exercise or conversion of outstanding options, warrants or other securities but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (2) Subject to the last sentence of paragraph (7) of this Section 2(b), in case the Company shall issue rights, options or warrants to all holders of its Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (determined as provided in paragraph (8) of this Section 2(b)) of the Common Stock on the Determination Date for such distribution, the Conversion Rate in effect at the opening of business on the day following such Determination Date shall be increased by dividing such Conversion Rate by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on such Determination Date plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such current market price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on such Determination Date plus the number of shares of Common Stock so offered for subscription or purchase, such increase to become effective immediately after the opening of business on the day following such Determination Date. For the purposes of this paragraph (2), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company or issuable upon the exercise or conversion of outstanding options, warrants or other securities but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not issue any rights, options or warrants in respect of shares of Common Stock held in the treasury of the Company. (3) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (4) Subject to the last sentence of paragraph (7) of this Section 2(b), in case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness, shares of any class of capital stock, or other property (including securities, but excluding (i) any rights, options or warrants referred to in paragraph (2) of this Section 2(b), (ii) any dividend or distribution paid exclusively in cash, (iii) any dividend or distribution referred to in paragraph (1) of this Section 2(b) and (iv) any merger or consolidation to which Section 2(h) applies), the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the Determination Date for such distribution by a fraction of which the numerator shall be the current market price per share (determined as provided in paragraph (8) of this Section 2(b)) of the Common Stock on such Determination Date less the then fair market value (as determined in good faith by the Board of Directors of the Company) of the portion of the assets, shares or evidences of indebtedness so distributed applicable to one share of Common Stock and the denominator shall be such current market price per share of the Common Stock, such adjustment to become effective immediately prior to the opening of business on the day following such Determination Date. If the Board of Directors determines the fair market value of any distribution for purposes of this paragraph (4) by reference to the actual or when issued trading market for any securities constituting such distribution, it must in doing so consider the prices in such market over the same period used in computing the current market price per share pursuant to paragraph (8) of this Section 2(b). (5) In case the Company shall, by dividend or otherwise, make a Cash Distribution, then, and in each such case, immediately after the close of business on the Determination Date for such Cash 4 12 CONFIDENTIAL TREATMENT--EDITED COPY Distribution, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on such Determination Date by a fraction (a) the numerator of which shall be equal to the current market price per share (determined as provided in paragraph (8) of this Section 2(b)) of the Common Stock on such Determination Date less an amount equal to the quotient of (1) the amount of such Cash Distribution divided by (2) the number of shares of Common Stock outstanding on such Determination Date and (b) the denominator of which shall be equal to the current market price per share (determined as provided in paragraph (8) of this Section 2(b)) of the Common Stock on such Determination Date. (6) In case the Company or any Subsidiary shall make an Excess Purchase Payment, then, and in each such case, immediately prior to the opening of business on the day after the tender offer in respect of which such Excess Purchase Payment is to be made expires, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the Determination Date for such tender offer by a fraction (a) the numerator of which shall be equal to the current market price per share (determined as provided in paragraph 8) of this Section 2(b)) of the Common Stock on such Determination Date less an amount equal to the quotient of (A) the Excess Purchase Payment divided by (B) the number of shares of Common Stock outstanding (including any tendered shares) as of the Determination Date less the number of all shares validly tendered and not withdrawn as of the Determination Date and (b) the denominator of which shall be equal to the current market price per share (determined as provided in paragraph (8) of this Section 2(b)) of the Common Stock as of such Determination Date. (7) (The reclassification of Common Stock into securities other than Common Stock (other than any reclassification upon a consolidation or merger to which Section 2(h) applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be the Determination Date), and (b) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision becomes effective" or "the day upon which such combination becomes effective", as the case may be, and "the day upon which such subdivision or combination becomes effective" within the meaning of paragraph (3) of this Section 2(b)). Rights or warrants issued by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of Common Stock, which rights or warrants (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are also issued in respect of future issuances of Common Stock, in each case in clauses (i) through (iii) until the occurrence of a specified event or events ("Trigger Event"), shall for purposes of this Section 2(b) not be deemed issued until the occurrence of the earliest Trigger Event. (8) For the purpose of any computation under paragraphs (2), (4), (5) or (6) of this Section 2(b), the current market price per share of Common Stock on any date shall be calculated by the Company and be deemed to be the average of the daily Closing Prices for the five consecutive Trading Days commencing seven Trading Days before the earlier of (i) the day in question and (ii) the day before the "ex" date with respect to the issuance or distribution requiring such computation. For purposes of this paragraph, the term "ex date", when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way in the applicable securities market or on the applicable securities exchange without the right to receive such issuance or distribution. (9) No adjustment in the Conversion Rate shall be required unless such adjustment (plus any adjustments not previously made by reason of this paragraph (9)) would require an increase or decrease of at least one-half of one percent in such rate; provided, however, that any adjustments which by reason of this paragraph (9) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 2 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. (10) The Company may make such increases in the Conversion Rate, for the remaining term of the Securities or any shorter term, in addition to those required by paragraphs (1), (2), (3), (4), (5) and (6) of this Section 2(b), as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. 5 13 CONFIDENTIAL TREATMENT--EDITED COPY (c) Whenever the Conversion Rate is adjusted as provided in Section 2(b), the Company shall compute the adjusted Conversion Rate in accordance with Section 2(b) and shall prepare a certificate signed by the chief financial officer of the Company setting forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based, and shall promptly deliver such certificate to the holder of this Security. (d) In case: (1) the Company shall declare a dividend or other distribution on its Common Stock payable (i) otherwise than exclusively in cash or (ii) exclusively in cash in an amount that would require any adjustment pursuant to Section 2(b); or (2) the Company shall authorize the granting to the holders of its Common Stock of rights, options or warrants to subscribe for or purchase any shares of capital stock of any class or of any other rights; or (3) of any reclassification of the Common Stock of the Company, or of any consolidation, merger or share exchange to which the Company is a party and for which approval of any shareholders of the Company is required, or of the conveyance, sale, transfer or lease of all or substantially all of the assets of the Company; or (4) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or (5) the Company or any Subsidiary shall commence a tender offer for all or a portion of the Company's outstanding shares of Common Stock (or shall amend any such tender offer); then the Company shall cause to be delivered to the holder of this Security, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record, expiration or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, rights, options or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights, options or warrants are to be determined, (y) the date on which the right to make tenders under such tender offer expires or (z) the date on which such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, conveyance, transfer, sale, lease, dissolution, liquidation or winding up. Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings described in clauses (1) through (5) of this Section 2(d). (e) The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of the Security, the full number of shares of Common Stock then issuable upon the conversion of this Security. (f) Except as provided in the next sentence, the Company will pay any and all taxes and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of the Security. The Company shall not, however, be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the holder of this Security, 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 duty, or has established to the satisfaction of the Company that such tax or duty has been paid. (g) The Company agrees that all shares of Common Stock which may be delivered upon conversion of the Security, upon such delivery, will have been duly authorized and validly issued and will be fully paid and nonassessable (and shall be issued out of the Company's authorized but unissued Common Stock) and, except as provided in Section 2(f), the Company will pay all taxes, liens and charges with respect to the issue thereof. 6 14 CONFIDENTIAL TREATMENT--EDITED COPY (h) In case of any consolidation of the Company with any other person, any merger of the Company into another person or of another person into the Company (other than a merger which does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the Company) or any conveyance, sale, transfer or lease of all or substantially all of the properties and assets of the Company, the person formed by such consolidation or resulting from such merger or which acquires such properties and assets, as the case may be, shall execute and deliver to the holder of this Security a supplemental agreement providing that such holder have the right thereafter, during the period this Security shall be convertible as specified in Section 2(a), to convert this Security only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease (including any Common Stock retainable) by a holder of the number of shares of Common Stock of the Company into which this Security might have been converted immediately prior to such consolidation, merger, conveyance, sale, transfer or lease, assuming such holder of Common Stock of the Company (i) is not a person with which the Company consolidated, into which the Company merged or which merged into the Company or to which such conveyance, sale, transfer or lease was made, as the case may be (a "Constituent Person"), or an Affiliate of a Constituent Person 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, conveyance, sale, transfer or lease (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer, or lease is not the same for each share of Common Stock of the Company held immediately prior to such consolidation, merger, conveyance, sale, transfer or lease 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 2(h) the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, sale, transfer or lease by the holders of 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 supplemental agreement shall provide for adjustments which, for events subsequent to the effective date of such supplemental agreement, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 2.

Subject to the provisions of Section 2(h), shares issuable on conversion or repurchase of this Security, or in payment of the principal hereof at maturity, shall include only shares of Common Stock or shares of any class or classes of common stock resulting from any reclassification or reclassifications thereof; provided, however, that if at any time there shall be more than one such resulting class, the shares so issuable on conversion of this Security shall include shares of all such classes, and the shares of each such class then so issuable shall be substantially in the proportion which the total number of shares of such class resulting from all such reclassifications bears to the total number of shares of all such classes resulting from all such reclassifications. "Determination Date" means, in the case of a dividend or other distribution, including the issuance of rights, options or warrants, to all shareholders, the date fixed for the determination of shareholders entitled to receive such dividend or other distribution and, in the case of a tender offer, the last time that tenders could have been made pursuant to such tender offer.

Right to Require Repurchase. (a) In the event that a Change in Control (as hereinafter defined) shall occur, then the holder of this Security shall have the right, at such holder's option, to require the Company to repurchase, and upon the exercise of such right the Company shall repurchase, this Security, or any portion of the principal amount hereof that is equal to $1,000 or any integral multiple thereof, on the date (the "Repurchase Date") that is 15 Trading Days after the date on which the Company gives notice of such Change of Control to the holder of this Security, at a purchase price equal to the Repurchase Price. At the option of the Company, the Repurchase Price may be paid in cash or, subject to the fulfillment by the Company of the conditions set forth in Section 3(b), by delivery of shares of Common Stock having a fair market value equal to the Repurchase Price as described in Section 3(b).

Notwithstanding any other provision of this Security, the Company shall, if the holder so elects, deliver the shares of Common Stock issuable pursuant to this Section 3 to any third party designated by the holder. If all of the conditions set forth in this Section 3(b) are not satisfied in accordance with the terms thereof, the Repurchase Price shall be paid by the Company only in cash. (c) To exercise a repurchase right, the holder shall deliver to the Company on or before the 10th day prior to the Repurchase Date, together with this Security, written notice of the holder's exercise of such right, which notice shall set forth the name of the holder, the principal amount of this Security to be repurchased (and, if this Security is to be repurchased in part, the portion of the principal amount thereof to be repurchased and the name of the person in which the portion thereof to remain outstanding after such repurchase is to be registered) and a statement that an election to exercise the repurchase right is being made thereby, and, in the event that the Repurchase Price shall be paid in shares of Common Stock, the name or names (with addresses) in which the certificate or certificates for shares of Common Stock shall be issued.

(d) In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to the holder the Repurchase Price in cash or shares of Common Stock, as provided above, on or prior to the Repurchase Date.

Subject to Section 2(b), no payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of this Security declared prior to the Repurchase Date.
