Ladies and Gentlemen:

Reference is made to the Agreement and Plan of Merger, dated as of the date hereof, by and among SKBHC Holdings LLC, a Delaware limited liability company (“Holdings”), Starbuck Bancshares, Inc., a Minnesota corporation (“Silicon”), and Banner Corporation, a Washington corporation (“Boron”) (such agreement, the “Merger Agreement”). Certain capitalized terms used in this investor letter agreement shall have the meanings ascribed to such terms in Section 7.

The undersigned, collectively a Major Silicon Member (the “Subject Seller”), will receive at the Effective Time cash and shares of Boron Common Stock as part of the Merger Consideration (such shares, the “Merger Consideration Shares”). In order to induce Boron to enter into the Merger Agreement and for other good and valuable consideration, the Subject Seller and Boron have entered into this investor letter agreement (this “Agreement”). Boron has provided to the Subject Seller true and complete copies of the investor letter agreements to be entered contemporaneously herewith by the other Major Silicon Members and Boron.

1.Commitment to Comply with Requirements of Regulatory Agencies and Governmental Entities. The Subject Seller shall, and shall cause its Subsidiaries and other Affiliates (collectively with the Subject Seller, the “Subject Seller Group”) to (a) if required by the staff of the Federal Reserve Board in connection with obtaining the Requisite Regulatory Approvals, promptly deliver to the Federal Reserve Board executed passivity and anti-association commitments substantially in the form attached hereto as Annex A (or in such other form as may be reasonably required by the Federal Reserve Board that is no less favorable in any material respect to the Subject Seller Group than the commitments attached hereto as Annex A) and (b) if required by the staff of the Federal Reserve Board or FDIC, use its commercially reasonable efforts to promptly provide directly to the Federal Reserve Board or FDIC, as applicable, such information about the Subject Seller Group as is reasonable and customary in connection with obtaining the Requisite Regulatory Approvals. The Subject Seller shall not be required to provide any information specified in the foregoing clause (b) directly to Silicon, Boron or any other Silicon Shareholder. Notwithstanding anything herein to the contrary, except as set forth in the first sentence of this Section 1, the Subject Seller and its Affiliates (other than, to avoid doubt, Holdings and its Subsidiaries) shall not be required to file any applications, notices, petitions or filings with, or seek any permits, consents or approvals, or authorizations from, any Regulatory Agency or Governmental Entity in connection with the transactions contemplated by the Merger Agreement or the Bank Merger.

2.Transfer Restrictions.

(a)The Subject Seller agrees to the following terms and conditions regarding the Subject Seller’s ownership of the Merger Consideration Shares:

(i) The Subject Seller shall not Transfer any Holdings Common Interests or Holdings Management Units (in each case other than through the exercise or conversion of any such securities pursuant to their terms or the terms of the Merger Agreement) between the date hereof and the Closing, other than Transfers to a Controlled Affiliate of such Person that agrees to be bound by the provisions of this Agreement as if it were the Subject Seller hereunder (a “Permitted Transferee”).

(ii) Neither the Subject Seller nor any of its Permitted Transferees shall Transfer any of the Merger Consideration Shares, other than to a Permitted Transferee, prior to the date that is thirty (30) days after the Closing Date (the “Lockup Termination Date”).

(iii) In the event that following the date hereof and prior to the Lockup Termination Date any Permitted Transferee ceases to be a Controlled Affiliate of the applicable Transferring Seller, then any prior Transfer to such Person pursuant to such exception in (i) or (ii) above shall become null and void and ownership and title to any such securities so Transferred shall revert to such applicable Transferring Seller. The Subject Seller shall promptly, and in any event no later than five (5) Business Days, notify Boron in writing following any Transfer to a Permitted Transferee.

(iv) From and after the Lockup Termination Date, the Subject Seller shall not Transfer any shares of Boron Common Stock received as part of the Merger Consideration to any Person or Group who, to the Subject Seller’s Knowledge, after giving effect to such Transfer, would beneficially own eight percent (8%) or more of the outstanding shares of Boron Common Stock; provided that the restriction shall not apply to Transfers effected through an Underwritten Offering (as defined in Annex B hereto) pursuant to an exercise of the registration rights provided for in Annex B hereto, to any Person or Persons pursuant to Rule 144 (as defined in Annex B hereto) or to a Transfer to any Person or Persons not Affiliated with the Subject Seller who are acquiring majority control of Boron in a (i) merger or similar business combination transaction or (ii) a tender offer approved or recommended by the Board of Directors of Boron.

(b)The Subject Seller shall not, and shall cause each other member of the Subject Seller Group not to, directly or indirectly, without Boron’s prior written consent:

-2-

Non-Voting Common Stock equal to ten percent (10%) or more of the number of outstanding shares of Boron Common Stock (as reported in the most recent Boron Report publicly filed under the Exchange Act);

(ii) make, or in any way participate, directly or indirectly, in any “solicitation” of “proxies” to vote (as such terms are used in the rules of the SEC), or seek to advise or influence any Person with respect to the voting of any voting securities of Boron;

(iii) form, join or in any way participate in a Group (other than with an Affiliate of the Subject Seller), with respect to any voting securities of Boron; or

(iv) publicly disclose any intention, plan or arrangement prohibited by, or inconsistent with, the foregoing;

provided that this Section 2(b) shall in no way limit (x) the activities of any director of Boron taken in good faith solely in his or her capacity as a director of Boron or (y) the right or ability of the Subject Seller to vote any voting securities of Boron (including the Merger Consideration Shares) with respect to any matter; provided, further, that the Subject Seller does not make any public announcement or public communication with respect to the manner in which the Subject Seller intends to vote such voting securities with respect to any matter. The Subject Seller further agrees, that it shall not, and shall cause each other member of the Subject Seller Group not to, without the written consent of Boron, publicly request Boron to amend or waive any provision of this Section 2(b) (including this sentence) or do so in a manner that would require Boron to publicly disclose such request.

(c)The foregoing restrictions on Transfer may be waived by Boron in writing with respect to any specific Transfer. The provisions in this Section 2 shall terminate and be of no further force and effect with respect to the Subject Seller (and its Permitted Transferees) on the earlier of (i) the first date when the Subject Seller (and any such Permitted Transferees) beneficially own less than five percent (5%) of the outstanding shares of Boron Common Stock and Boron Non-Voting Common Stock (as reported in the most recent Boron Report publicly filed under the Exchange Act), excluding the dilutive effect of any primary issuances of Boron Common Stock or Boron Non-Voting Common Stock (or any other securities convertible into or exchangeable for Boron Common Stock or and Boron Non-Voting Common Stock) by Boron, and (ii) the breach, in any material respect, by Boron of any of its obligations in this Agreement.

(d)Any Transfer or attempted Transfer of Merger Consideration Shares in violation of this Section 2 shall, to the fullest extent permitted by applicable Law, be null and void ab initio, and Boron shall not, and shall instruct its transfer agent and other third parties not to, record or recognize any such purported transaction on the share register of Boron.

(e)Any certificates for Merger Consideration Shares issued to the Subject Seller or any Permitted Transferee pursuant to the Merger Agreement shall bear a legend or legends (and appropriate comparable notations or other arrangements will be made with respect to any uncertificated shares) in addition to the legend contemplated by Section 2.2(b) of the Merger

-3-

“The securities evidenced by this certificate are subject to restrictions on transfer set forth in an Investor Letter Agreement, dated November 5, 2014, among Boron and certain other parties thereto (a copy of which is on file with the Secretary of Boron).”

(f)Notwithstanding the foregoing, upon the request of a holder of certificate(s) for Merger Consideration Shares, Boron agrees that it shall cause, and take all actions necessary to ensure, the prompt removal of the legend contemplated by Section 2.2(b) of the Merger Agreement and, if applicable, the legend contemplated in Section 2(e) (together with the elimination or termination of any notations or arrangements described therein) from such holder’s Merger Consideration Shares (including executing and delivering an opinion of counsel and instruction letter satisfactory to the transfer agent of Boron Common Stock) and cause the deposit of such holder’s Merger Consideration Shares in book-entry form with the appropriate unrestricted CUSIP number to the account specified by such holder, provided, that the restrictions described in such legends (or notations or arrangements) are no longer applicable (including where the Subject Seller and its Permitted Tranferees no longer own or will own such Merger Consideration Shares).

(b)Continued Effectiveness. Until the earlier of (i) such time as all Registrable Securities cease to be Registrable Securities or (ii) Boron is no longer eligible to maintain a Shelf Registration Statement, Boron will keep current and effective any Shelf Registration Statement filed pursuant to Section 2.01(a), and file such supplements or amendments to such Shelf Registration Statement as may be necessary or appropriate in order to keep such Shelf Registration Statement continuously effective and useable for the resale of Registrable Securities under the Securities Act. In the event that Boron is no longer eligible to maintain a Shelf Registration Statement, Boron shall provide written notice to the Shareholders of such ineligibility within two (2) Business Days of the date on which Boron becomes aware of such ineligibility. Boron shall use reasonable best efforts to cause the Registrable Securities to, on or prior to the Lockup Termination Date, be qualified for trading on any securities exchange on which the Boron Common Stock is listed or quoted.

(c)Use of Shelf Registration Statement. Following the Lockup Termination Date, each Shareholder shall have the right to use any Shelf Registration Statement then effective to Transfer all or a portion of its Registrable Securities (i) in an unrestricted number of brokered transactions and (ii) Underwritten Offerings in accordance with Section 2.01(d).

(d)Underwritten Offerings pursuant to Shelf Registration Statement. Upon the receipt by Boron of a written request from (i) any Major Silicon Member that desires to sell Registrable Securities in an Underwritten Offering that is not a Marketed Underwritten Offering or (ii) a majority of the Registrable Securities then held by the Major Silicon Members with respect to a Marketed Underwritten Offering, in each case pursuant to a Shelf Registration Statement, Boron will give written notice of such request to all other Shareholders, which notice shall be given in any event within three (3) Business Days of the date on which Boron received the initial request. Any other Shareholders that desire to sell Registrable Securities in such Underwritten Offering shall give written notice to Boron within ten (10) Business Days after the date Boron gave such other Shareholders notice of the such initial request specifying the number of Registrable Securities proposed by such Shareholder to be included in such Underwritten Offering. A Shareholder may change the number of Registrable Securities proposed to be offered in any such Underwritten Offering at any time prior to commencement of such offering so long as such change would not materially adversely affect the timing or success of such Underwritten Offering; provided, however, that Boron shall be entitled to reasonably delay an Underwritten Offering to the extent resulting from such change. Boron will cooperate with such Shareholders and any Underwriter in effecting an Underwritten Offering pursuant to the Shelf Registration Statement as promptly as reasonably practicable with respect to all such Registrable Securities, subject to the limitations and conditions with respect to Underwritten Offerings (the “Underwritten Offering Limitations”):

(i)Boron shall not be required to effect more than eight (8) Underwritten Offerings in the aggregate, of which no more than three (3) may be Marketed Underwritten Offerings.

(ii)Boron shall not be required to effect (A) any Marketed Underwritten Offering within one hundred and eighty (180) days after another Marketed Underwritten Offering, and (B) any Underwritten Offering within ninety (90) days after another Underwritten Offering.

(v)With respect to an Underwritten Offering that is not a Marketed Underwritten Offering, the relevant Major Silicon Members shall be entitled to select the nationally recognized investment banking firm to serve as a lead Underwriter and, if applicable, any additional Underwriters.

(e)Effect on Demand Registration Obligations. The provisions of Section 2.02 shall not apply at any time Boron is eligible to file and maintain the effectiveness of a Shelf Registration Statement and so maintains the effectiveness of such Shelf Registration Statement.

Section 2.02.Demand Registration.

(a)Demand by Shareholders. If at any time after the Lockup Termination Date and prior to Boron effecting eight (8) Underwritten Offerings pursuant to Section 2.01(d), Boron is no longer eligible to use a Shelf Registration Statement, within ninety (90) days after the written request of Shareholders holding a majority of the Registrable Securities then held by the Shareholders to register the resale of a specified amount of the Registrable Securities under the Securities Act pursuant to an Underwritten Offering (a “Demand Notice”), Boron will (i) give written notice of such request to all other Shareholders (which notice shall be given in any event within three (3) Business Days of the date on which Boron received the applicable Demand Notice) and will use its reasonable best efforts to register, in accordance with the provisions of this Agreement, all Registrable Securities that have been requested to be registered in the Demand Notice or by any other Shareholders by written notice to Boron given within ten (10) Business Days after the date Boron gave such other Shareholders notice of the Demand Notice (collectively, the “Demand Shareholders”) and (ii) will file a Registration Statement, on an appropriate form which Boron is then eligible to use, to register the resale of such Registrable Securities in an Underwritten Offering (each such registration, a “Demand Registration”). Each Demand Notice will specify the number of Registrable Securities proposed to be offered for sale. The Demand Shareholders may change the number of Registrable Securities proposed to be offered pursuant to any Demand Registration at any time prior to commencement of the offering so long as such change would not materially adversely affect the timing or success of the offering. Subject to Section 2.05 and with the written consent of Shareholders holding a majority of the Registrable Securities included in the Demand Registration (such consent not to

B-6

be unreasonably withheld), Boron may include in any registration effected pursuant this Section 2.02 any securities for its own account or for the account of holders of Boron Common Stock (other than the Shareholders).

(b)Effective Registration. Boron will use its reasonable best efforts to (i) cause any Registration Statement filed in connection with a Demand Registration to be declared effective (unless it becomes effective automatically upon filing) as promptly as practicable after the filing thereof with the SEC and (ii) keep such Registration Statement current and effective for a period of not less than ninety (90) days or such longer period as, based upon the opinion of counsel for the underwriters, a prospectus is required by law to be delivered in connection with the sale of Registrable Securities by an underwriter or dealer. Boron further agrees to supplement or make amendments to each such Registration Statement as may be necessary to keep such Registration Statement effective for the period referred to in clause (ii) above, including (A) to respond to the comments of the SEC, if any, (B) as may be required by the registration form utilized by Boron for such Registration Statement or by the instructions to such registration form, (C) as may be required by the Securities Act or (D) as may be reasonably requested in writing by the Demand Shareholders or any Underwriter and reasonably acceptable to Boron.

(c)Limitations. Boron’s obligations in this Section 2.02 shall be subject to the Underwritten Offering Limitations.

Section 2.03.Piggyback Registration. If at any time after the Lockup Termination Date and in addition to the Shareholders’ rights in Section 2.01 and Section 2.02, Boron proposes to file a registration statement under the Securities Act or consummate an Underwritten Offering with respect to an offering of Equity Interests for (a) Boron’s own account (other than a Registration Statement on Form S-4 or S-8 (or any substitute form that may be adopted by the SEC)) or (b) the account of any holder of Boron Common Stock (other than a Shareholder), then Boron shall give written notice of such proposed filing or Underwritten Offering to the Shareholders as soon as practicable (but in no event less than ten (10) Business Days before the anticipated filing date). Upon a written request given by any Shareholders to Boron within five (5) Business Days after delivery of any such notice by Boron, to include Registrable Securities in such registration or Underwritten Offering, as applicable (which request shall specify the number of Registrable Securities proposed to be included in such registration or Underwritten Offering, as applicable), Boron shall, subject to the following proviso, include all such requested Registrable Securities in such registration or Underwritten Offering, as applicable, on the same terms and conditions as applicable to Boron’s or such holder’s shares of Boron Common Stock (a “Piggyback Registration”); provided, however, that if at any time after giving written notice of such proposed filing or Underwritten Offering, as applicable, and prior to the effective date of the Registration Statement filed in connection with such registration, or the consummation of such Underwritten Offering, as applicable, Boron shall determine for any reason not to proceed with the proposed registration or disposition, as applicable, of the Equity Interests, then Boron may, at its election, give written notice of such determination to such Shareholders and, thereupon, will be relieved of its obligation to register any Registrable Securities in connection with such registration, or dispose of any Registrable Securities in connection with such Underwritten Offering, as applicable. Such Shareholders shall, subject to Section 2.06(b), enter into a customary underwriting agreement with the Underwriter or

B-7

Underwriters selected by Boron with respect to any Registrable Securities sold by such Shareholders pursuant to this Section 2.03. No registration of Registrable Securities effected pursuant to a request under this Section 2.03 shall relieve Boron of its obligations under Section 2.01 or Section 2.02.

Section 2.04.Withdrawal of Request for Underwritten Offering or Demand Registration. A requesting Major Silicon Member or, as applicable, requesting Shareholders holding a majority of the Registrable Securities then held by the Shareholders will be permitted to rescind a request for an Underwritten Offering pursuant to a Shelf Registration Statement or a request for a Demand Registration without having to reimburse Boron for any expenses; provided that should a requesting Major Silicon Member or, as applicable, requesting Shareholders holding a majority of the Registrable Securities that previously made such request rescind such request in writing (for the avoidance of doubt, a delay in the timing of an Underwritten Offering or a reduction in the number of Registrable Securities proposed to be offered shall not be deemed a rescission), each such rescinding Major Silicon Member or Shareholder shall promptly reimburse Boron for the reasonable out of pocket expenses incurred by Boron in connection with such request on a pro rata basis in accordance with the number of Registrable Securities that each such Major Silicon Member or Shareholder originally intended to be offered, and following such reimbursement and such request will not count as a request for an Underwritten Offering or Demand Registration for purposes of determining when future Underwritten Offerings or Demand Registrations may be requested by Major Silicon Members or Shareholders pursuant to Section 2.01 or Section 2.02.

Section 2.05.Reduction of Size of Underwritten Offering. Notwithstanding anything to the contrary contained herein, if the lead Underwriter(s) of an Underwritten Offering advises Boron in writing that, in its reasonable opinion the number of shares of Boron Common Stock (including any Registrable Securities) that Boron, Shareholders and any other Persons intend to include in any Registration Statement or dispose of pursuant to any Underwritten Offering exceeds the number that can be sold without materially and adversely affecting the price at which the securities can be sold, then the number of shares of Boron Common Stock to be included in the Registration Statement, or disposed of pursuant to such Underwritten Offering, as applicable, for the account of Boron, Shareholders and any other Persons will be reduced to the extent necessary to reduce the total number of securities to be included in any such Registration Statement or disposed of pursuant to such Underwritten Offering, as applicable, to the number recommended by such lead Underwriter(s); provided, however, that such reduction shall be made in accordance with the following priorities:

(ii)in any Underwritten Offering, the relevant Shareholders together with Boron and any other holders of Boron’s securities proposing to include securities in any Underwritten Offering, will enter into a customary underwriting agreement in accordance with Section 2.06(b) with the Underwriter or Underwriters selected for such underwriting, as well as such other documents customary in similar offerings.

(b)The Shareholders agrees that, upon receipt of any notice from Boron of the happening of any event of the kind described in Section 2.06(a)(iv) or 2.06(a)(v) or a condition described in Section 2.08(a), the Shareholders will forthwith discontinue disposition of such Registrable Securities pursuant to the Registration Statement covering the sale of such Registrable Securities until the Shareholder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 2.06(a)(iv) or notice from Boron of the termination of the stop order or Suspension Period. In the event Boron gives any such notice, the applicable time period mentioned in Section 2.02(b) during which a Registration Statement is to remain effective will be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this Section 2.07(b) to and including the date when the Shareholders will have received the copies of the supplemented or amended prospectus contemplated by Section 2.06(a)(iv) or notice from Boron of the termination of the stop order or Suspension Period.

(c)Each Shareholder agrees that to the extent timely notified in writing by the Underwriters managing any Underwritten Offering by Boron of shares of Boron Common Stock or any securities convertible into or exchangeable or exercisable for shares of Boron Common Stock, each such Shareholder that is participating in such Underwritten Offering shall agree (the “Underwriter’s Lockup”) not to Transfer any Shares without the prior written consent of Boron or such Underwriters during the period beginning seven (7) days before and ending one hundred twenty (120) days (or, in either case, such lesser period as may be permitted for all Shareholders by Boron or such managing Underwriter or Underwriters) after the pricing date of such Underwritten Offering, subject to any exceptions permitted by such managing Underwriter or Underwriters; provided that any Underwriter’s Lockup shall contain customary exceptions providing that such Shareholder and its Affiliates, other than such Shareholder, may engage in brokerage, investment advisory, financial advisory, anti-raid advisory, merger advisory, financing, asset management, trading, market making, arbitrage, principal investing and other similar activities conducted in the ordinary course of their Affiliates’ business, other than with respect to the Shares owned by such Shareholder. The Underwriter’s Lockup shall provide that if all or a portion of the Shares of any Shareholder is released from an Underwriter’s Lockup or all or a portion of the Shares of any other party who entered into a substantially similar agreement with the Underwriters in connection with such Underwritten Offering is released from such agreement, then the same percentage of the shares of each Shareholder shall be released from the Underwriter’s Lockup.

Section 2.08.          Suspension Period.

(a)Notwithstanding anything to the contrary contained in this Agreement, if the filing, initial effectiveness or continued use of (i) any Shelf Registration Statement for resales of Registrable Securities pursuant to Section 2.01 or Section 2.03 or (ii) any Registration Statement for resales of Registrable Securities pursuant to Section 2.02 or Section 2.03 at any time would, (A) in the good faith judgment of the Board of Directors of Boron, (i) require the disclosure of material non-public information by Boron, the premature disclosure of which at such time would be materially detrimental to Boron, or (ii) require the disclosure in any such Shelf Registration Statement or Registration Statement of a contemplated bona fide material financing, acquisition, corporate reorganization or other similar material transaction or other material event or circumstance affecting Boron, the premature disclosure of which at such time would be materially detrimental to Boron or the holders of Boron Common Stock; or (B) require the inclusion, at that time, in such Shelf Registration Statement or Registration Statement, as applicable, of financial statements of a business to be acquired, or pro forma financial statements reflecting the acquisition of such business, where the business combination has occurred, or is probable, and such financial statements are not then available to Boron for reasons beyond Boron’s control; provided, in the case of this clause (B), that Boron shall use its reasonable best efforts to obtain such financial statements as promptly as practicable, Boron shall be entitled, from time to time, by delivering a certificate signed by the chief executive officer or the chief financial officer of Boron to the Shareholders certifying to the determination of the board of directors of Boron described above, to require the Shareholders to suspend the use of the Prospectus included in any Shelf Registration Statement or to postpone the filing or suspend the use of any Registration Statement for a reasonable period of time not to exceed sixty (60) days in succession (or a longer period of time with the prior written consent of a majority of the Shareholders, which consent shall not be unreasonably withheld), one hundred and twenty (120) days in the aggregate in any one-year period or three (3) times in any one-year period (a “Suspension Period”); provided that Boron shall not register any securities for sale for its own account or that of any other shareholder during any Suspension Period. In the event of any such suspension pursuant to this Section 2.08(a), Boron shall furnish to the Shareholders a written notice setting forth the estimated length of the anticipated delay. Boron will use reasonable best efforts to limit the length of any Suspension Period and shall notify the Shareholders promptly upon the termination of the Suspension Period. Notice of the commencement of a Suspension Period shall simply specify such commencement and shall not contain any facts or circumstances relating to such commencement or any material non-public information. Boron shall respond promptly to reasonable inquiry by a Shareholder as to such facts and circumstances. Upon notice by Boron to the Shareholders of any determination to commence a Suspension Period, the Shareholders shall keep the fact of any such Suspension Period strictly confidential, and during any Suspension Period, promptly halt any offer, sale, trading or transfer of any Boron Common Stock pursuant to such Prospectus for the duration of the Suspension Period until (x) the Suspension Period has expired or, if earlier (y) Boron has provided notice that the Suspension Period has been terminated.

(b)After the expiration of any Suspension Period and without any further request from a Shareholder, Boron shall as promptly as reasonably practicable prepare a Registration Statement or post-effective amendment or supplement to the applicable shelf Registration Statement or Prospectus, or any document incorporated therein by reference, or file

B-15

any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, if necessary so that the Prospectus will not include a material misstatement or omission or be not effective and useable for resale of Registrable Securities.

Section 2.09.Registration Expenses. Subject to Section 2.04, all fees and expenses incurred by Boron in effecting any registration pursuant to this Article II, including all fees and expenses incurred in complying with securities or “blue sky” laws, printing expenses, any registration or filing fees payable under any federal or state securities or “blue sky” laws, the fees and expenses incurred in connection with any listing or quoting of the securities to be registered on any national securities exchange or automated quotation system, fees of FINRA, fees and disbursements of counsel for Boron, fees and disbursements of one counsel for the holders of Registrable Securities whose shares are included in a Registration Statement or Underwritten Offering, which counsel shall be selected by the holders of a majority of the Registrable Securities being sold pursuant to such Registration Statement or Underwritten Offering, and fees and expenses of Boron’s independent registered certified public accounting firm, will be borne by Boron; provided, however, that the Shareholders will bear and pay any underwriting discounts, fees and commissions of any Underwriters and transfer taxes and any expenses required by applicable Law to be paid by a selling shareholder, in each case with respect to Registrable Securities offered for the Shareholders’ account pursuant to any Registration Statement.

Section 2.10.Rules 144 and 144A and Regulation S. Boron covenants that it will use reasonable best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder and it will use reasonable best efforts to take any such further action promptly as reasonably requested, all to the extent required from time to time to enable the Shareholders to sell Registrable Securities without registration under the Securities Act pursuant to (i) Rules 144, 144A or Regulation S under the Securities Act, as such provisions may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC. Upon the reasonable request of a Shareholder, Boron will deliver to such Shareholder a written statement as to whether it has complied with such requirements and, if not, the specifics thereof.

Section 2.11.Indemnification; Contribution. (a) In connection with any registration of Registrable Securities or Underwritten Offering pursuant to Section 2.01, Section 2.02 or Section 2.03, Boron will indemnify, defend and hold harmless each Shareholder, its Affiliates, directors, officers, shareholders and employees and each Person who controls such Shareholders within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the “Indemnified Persons”) from and against any and all Losses caused by any untrue or alleged untrue statement of material fact contained or incorporated by reference in any part of any Registration Statement or any Prospectus, including any amendment or supplement thereto, used in connection with the Registrable Securities, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading; provided, however, that Boron will not be required to indemnify any Indemnified Person for any such Loss arising out of or with respect to sales pursuant to the Registration Statement or Prospectus based upon information in the Registration Statement or Prospectus that was represented by Silicon or Silicon Holdings as true and correct

B-16

in the Merger Agreement, and with respect to which Boron would not have been reasonably expected to discover the failure of such information to be true and correct prior to the date of such sales.

(b)In connection with any Registration Statement or Prospectus, the Shareholders who sell Registrable Securities pursuant to such Registration Statement or Prospectus will severally but not jointly indemnify, defend and hold harmless Boron, its directors, its officers, its employees and each Person, if any, who controls Boron (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as the foregoing indemnity from Boron to the Shareholders, but only with respect to information arising out of or based upon information furnished in writing by such Shareholder or on such Shareholder’s behalf (in each case, in its capacity as a Shareholder), in either case expressly for use in any Registration Statement or any Prospectus, including any amendment or supplement thereto.

(c)In case any claim, action or proceeding (including any governmental investigation) is instituted involving any Person in respect of which indemnity may be sought pursuant to Section 2.11(a) or Section 2.11(b), such Person (the “Indemnified Party”) will promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing and the Indemnifying Party shall be entitled to participate therein and, to the extent it shall wish, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party and will pay the fees and disbursements of such counsel related to such proceeding; provided, however, that the failure or delay to give such notice shall not relieve the Indemnifying Party of its obligations pursuant to this Agreement except to the extent that it shall be determined by a court of competent jurisdiction that such Indemnifying Party has been prejudiced by such failure or delay. In any such claim, action or proceeding, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to retain its own counsel, but the fees and expenses of such counsel will be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party have mutually agreed to the retention of such counsel, (ii) the Indemnifying Party fails to assume the defense of the claim, action or proceeding within fifteen (15) Business Days following receipt of notice from the Indemnified Party or (iii) the Indemnified Party and the Indemnifying Party are both actual or potential defendants in, or targets of, any such action and the Indemnified Party has been advised by counsel that representation of both parties by the same counsel would be inappropriate due to actual or potential conflicting interests between them. It is understood that the Indemnifying Party will not, in connection with any claim, action or proceeding or related claims, actions or proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one (1) separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties and that all such reasonable fees and expenses will be reimbursed as they are incurred. In the case of the retention of any such separate firm for the Indemnified Parties, such firm will be designated in writing by the Indemnified Parties. The Indemnifying Party will not be liable for any settlement of any claim, action or proceeding effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed), but if such claim, action or proceeding is settled with such consent or if there has been a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any Loss by reason of such settlement or judgment. No Indemnifying Party will, without the prior written consent of the Indemnified Party, settle,

B-17

compromise or offer to settle or compromise any pending or threatened proceeding in respect of which any Indemnified Party is seeking indemnity hereunder, unless such settlement includes (i) an unconditional release of such Indemnified Party from all liability in connection with such proceeding, (ii) no finding or admission of any violation of Law or any violation of the rights of any Person by the Indemnified Party or any of its Affiliates can be made as the result of such action and (iii) the sole relief (if any) provided is monetary damages that are reimbursed in full by the Indemnifying Party.

(d)If the indemnification provided for in this Section 2.11 from the Indemnifying Party is unavailable to an Indemnified Party hereunder or is insufficient in respect of any Losses referred to in this Section 2.11, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, will contribute to the amount paid or payable by such Indemnified Party as a result of such Losses (i) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions that resulted in such Losses, as well as any other relevant equitable considerations, or (ii) if the allocation provided by clause (i) is not permitted by applicable Law, in such proportion as is appropriate to reflect not only the relative fault referred to in clause (i) but also the relative benefit of Boron, on the one hand, and such Shareholder, on the other, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party will be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been taken by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of the Losses referred to above will be deemed to include, subject to the limitations set forth in Section 2.11(c), any reasonable legal or other out of pocket fees or expenses reasonably incurred by such party in connection with any investigation or proceeding.

(e)The parties agree that it would not be just and equitable if contribution pursuant to Section 2.11(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in Section 2.11(d). No Person guilty of “fraudulent misrepresentation” (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. In no event shall any Shareholder be obligated to provide indemnification or contribution in excess of the net aggregate proceeds received from the sale of Registrable Securities pursuant to the applicable Registration Statement or Prospectus.

Section 2.12.Termination. The provisions in this Article II shall terminate with respect to each individual Shareholder on the first date when such Shareholder no longer holds any Registrable Securities.

Section 2.13.Participating Shareholder. By written notice delivered to Boron, any Shareholder (an “Opting-Out Shareholder”) may elect to waive its right to participate in Underwritten Offerings and to be a Piggyback Shareholder and participate in a Piggyback Registration (“Section 2.13 Opt-Out”), until such time as the written notice is rescinded in writing. During such time as a Section 2.13 Opt-Out is in effect: (a) the Opting-Out Shareholder

B-18

shall not receive notices of any proposed Underwritten Offering or Piggyback Registration, (b) shall not be entitled to participate in any such Underwritten Offering pursuant to Section 2.01(d) or Section 2.02(a), or Piggyback Registration pursuant to Section 2.03, and (c) shall not be subject to Section 2.07(c).

Section 2.14.No Waiver. Notwithstanding anything to the contrary contained herein, nothing in this Annex B shall be deemed a waiver by Boron of any restrictions on the Transfer of any Registrable Securities.

Section 2.15.Limitations on Subsequent Registration Rights. From and after the date of this Agreement, Boron shall not, without the prior written consent of Shareholders holding a majority of the Registrable Securities then held by the Shareholders, enter into any agreement with any holder or prospective holder of any Equity Interests that is inconsistent with the terms of this Agreement, including an agreement that would provide to such holder the right to include Equity Interests in any registration on other than (a) a pro rata basis with respect to the Registrable Securities or (b) on a subordinate basis after all applicable Shareholders have had the opportunity to include in the registration and offering all shares of Registrable Securities that they wish to so include. Boron is not a party to any agreement or arrangement providing registration rights to any other Person as of the date hereof.

Section 2.16.Recapitalizations, Exchanges Affecting the Registrable Securities. The provisions of this Agreement shall apply, to the full extent set forth herein, with respect to the Registrable Securities, to any and all shares of stock of Boron or any successor or assign of Boron (whether by merger, consolidation, sale of assets or otherwise) which may be issued in respect of, in exchange for, or in substitution of the Registrable Securities, by reason of a stock dividend, stock split, stock issuance, reverse stock split, combination, recapitalization, reclassification, merger, consolidation or otherwise. Upon the occurrence of any of such events, amounts hereunder shall be appropriately adjusted.
