WHEREAS, pursuant to that certain Agreement and Plan of Merger, dated as of December 14, 2011 (the “Merger Agreement”), among Parent, BLMS Inc., a California corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and the Company, Parent will acquire all outstanding shares of the Company effective on the date hereof upon the consummation of the merger contemplated by the Merger Agreement (such time of effectiveness, the “Effective Time”).

WHEREAS, pursuant to Section 1.6(a) of the Merger Agreement, each share of common stock, no par value, of the Company (the “Company Shares”), issued and outstanding immediately prior to the Effective Time (other than any Company Shares to be canceled pursuant to Section 1.6(b) thereof and any Dissenting Company Shares (as defined in the Merger Agreement)) will be canceled and converted automatically into the right to receive 1.125 fully paid and nonassessable shares of common stock, par value $0.001 per share, of Parent (the “Parent Shares”).

WHEREAS, pursuant to Section 5.16(b) of the Merger Agreement, Parent has agreed to enter into a supplemental indenture in respect of the Securities containing the provisions required by the Indenture, including a provision that, at the Effective Time, (1) each outstanding Security will no longer be convertible into Company Shares and will be convertible solely into Parent Shares and cash, pursuant to, and in accordance with, the terms of the Indenture, and (2) Parent will assume all of the obligations of the Company under the Securities, any coupons appertaining thereto and the Indenture.

WHEREAS, Section 8.07(a) of the Indenture requires that, upon the occurrence of, among other things, any consolidation, merger or combination of the Company with another Person, in each case as a result of which the Company Shares would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof), then, at the effective time of the transaction, the right to convert a Security will be changed to a right to convert each $1,000 principal amount of such Security into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of Company Shares equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to receive (the “Reference Property”) upon such transaction.

WHEREAS, Section 10.01 of the Indenture provides, among other things, that the Company shall not consolidate with or merge into any other Person unless the Surviving Entity expressly assumes by supplemental indenture, executed and delivered to the Trustee, all of the Company’s obligations under the Securities and the Indenture and that, if upon the occurrence of any such consolidation, merger, sale, conveyance, transfer or lease the Securities would become convertible into securities issued by an issuer other than the Surviving Entity, the issuer of the securities into which the Securities have become convertible shall fully and unconditionally guarantee, on a senior basis, the Surviving Entity’s obligations under the Securities.

WHEREAS, Section 14.01 of the Indenture provides that, without the consent of any Holders, the Company, when authorized by a Board Resolution, and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental thereto, in form satisfactory to the Trustee, to, among other things, provide for the assumption by a successor corporation of the Company’s obligations under the Indenture, add guarantees with respect to the Securities and make any change that does not adversely affect the rights of any Holder.

(x) Section 8.06 shall be amended and restated in full as follows:

“Section 8.06. Adjustment in Connection with a Make-Whole Fundamental Change. (a) If a Holder elects to convert Securities at any time following Parent’s or the Company’s delivery of a notice of a Make-Whole Fundamental Change and until (i) if such Make-Whole Fundamental Change is a Fundamental Change, the Fundamental Change Repurchase Date for such Fundamental Change, and (ii) if such Make-Whole Fundamental Change is not a Fundamental Change, the 35th Business Day immediately following the effective date of such Make-Whole Fundamental Change, the Conversion Rate for such Securities will be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below.

(b) The number of Additional Shares by which the Conversion Rate will be increased shall be determined by reference to the table attached as Exhibit B hereto, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Make-Whole Effective Date”) and the Stock Price; provided that if the actual Stock Price is between two Stock Price amounts in such table or the Make-Whole Effective Date is between two Make-Whole Effective Dates in such table, the number of Additional Shares shall be

- 17 -

determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Make-Whole Effective Dates, as applicable, based on a 365-day year; provided further that if (1) the Stock Price is greater than $75.56 per share of Common Stock (subject to adjustment in the same manner as set forth in Section 8.03), no Additional Shares will be added to the Conversion Rate, and (2) the Stock Price is less than $29.26 per share (subject to adjustment in the same manner as set forth in Section 8.03), no Additional Shares will be added to the Conversion Rate. Notwithstanding the foregoing, in no event will the Conversion Rate, as a result of a Make-Whole Fundamental Change, exceed 34.1738 shares per $1,000 Principal Amount (subject to adjustment in the same manner as set forth in Section 8.03).

(c) The Stock Prices set forth in the first row of the table in Exhibit B hereto shall be adjusted as of any date on which the Conversion Rate of the Securities is adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares within the table shall be adjusted in the same manner as the Conversion Rate as set forth in Section 8.03 (other than by operation of an adjustment to the Conversion Rate by adding Additional Shares).

(d) The table in Exhibit B hereto sets forth the hypothetical Stock Price and the number of Additional Shares to be received per $1,000 Principal Amount of Securities.

(e) Upon surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, Parent or the Company shall deliver an amount of cash and a number of shares of Common Stock pursuant to Section 8.02, provided, however, that if the Observation Period applicable to such Security ends on or prior to the effective date for such Make-Whole Fundamental Change, Parent or the Company shall deliver the portion of the Settlement Amount corresponding to the Additional Shares, if any, on the third Business Day immediately following the effective date for such Make-Whole Fundamental Change (for the avoidance of doubt, if an anticipated Make-Whole Fundamental Change does not occur, the Holder will not receive any portion of the Settlement Amount corresponding to such Additional Shares), and provided further that if the Holder converts its Securities after the effective date of such Make-Whole Fundamental Change and such Make-Whole Fundamental Change is described in clause (2) of the definition of Fundamental Change (regardless of the proviso to such clause) and the consideration for Common Stock in such Make-Whole Fundamental Change is comprised entirely of cash, the conversion obligation per $1,000 principal amount of Securities will be calculated based solely on the Stock Price for the transaction and will be deemed to be an amount equal to the applicable Conversion Rate (including any adjustment as described in this

- 18 -

Section 8.06) multiplied by such Stock Price. In such event, the Company will pay the conversion obligation in cash on the third Business Day following the Conversion Date. Parent or the Company, or Parent on behalf of the Company, will notify Holders of the effective date of any Make-Whole Fundamental Change and disseminate a press release through a recognized wire service announcing such effective date no later than five Business Days after such effective date.

(f) Parent shall notify Holders of the Securities, the Trustee and the Paying Agent of a Make-Whole Fundamental Change and the anticipated effective date of such Make-Whole Fundamental Change and disseminate a press release through a recognized wire service announcing the same no later than the 30th Scheduled Trading Day immediately preceding the anticipated effective date of such Make-Whole Fundamental Change, or, if Parent does not have knowledge of such Make-Whole Fundamental Change or such anticipated effective date at such time, on the third Business Day immediately following the date on which Parent receives notice, or otherwise becomes aware, of such Make-Whole Fundamental Change and such anticipated effective date, but in no event later than the actual effective date for such Make-Whole Fundamental Change.”

GUARANTEE

Section 15.01. Guarantee. Subject to the provisions of this Indenture and any supplemental indenture hereto, Parent hereby irrevocably and unconditionally guarantees, on a senior basis (the “Guarantee”), to each Holder of a Security outstanding on the date of the First Supplemental Indenture or any Security thereafter authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, that: (1) the principal of and interest on the Securities shall be paid in full when due, whether at maturity, by acceleration or otherwise; (2) in case of any extension of time in payment or renewal of any Securities or pursuant to any cure period provisions of the Securities or the Indenture, they shall be paid in full when due in accordance with the terms of the extension or renewal or cure period; and (3) all other obligations of the Company under the Securities and the Indenture shall be paid in full when due, whether at maturity, by acceleration or otherwise. Failing payment when due by the Company of any amount so guaranteed, Parent shall be obligated to pay the same. Parent agrees that this is a guarantee of payment and not a guarantee of collection.

Parent hereby agrees that its obligations with regard to the Guarantee shall be unconditional, irrespective of any circumstances which might otherwise constitute a legal or equitable defense of a guarantor. In the event of a default in the payment of principal or interest the Trustee or any Holder of Securities may seek to enforce the Guarantee against Parent without first proceeding against the Company.

- 24 -
