Form of Subscription Agreement, by and among Bellevue Life Sciences Acquisition Corp. and the investors signatory thereto

From and after the date of the issuance of each share of Series A Preferred Stock, dividends at the Applicable Rate per annum per share (the “Series A Dividend Rate”) shall accrue on such share of Series A Preferred Stock (the “Accruing Dividends”). For purposes hereof, the “Applicable Rate” means 5.0% of the Series A Original Issue Price (or such higher rate as provided in Section 8(a)). The Accruing Dividends shall be subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Series A Preferred Stock. Accruing Dividends shall accrue from day to day, whether or not declared, on each share of Series A Preferred Stock from the date of issuance thereof by the Corporation; provided, however, that except as set forth in the following sentence of this Section 2, such Accruing Dividends shall be payable only when, as, and if declared by the Board of Directors or as otherwise specifically provided herein. The Corporation shall not declare, pay or set aside any dividends on shares of any other class or series of Capital Stock of the Corporation (other than dividends on shares of Common Stock payable in shares of Common Stock) unless (in addition to the obtaining of any consents required elsewhere in the Certificate of Incorporation) the Holders of the Series A Preferred Stock then outstanding shall first receive, or simultaneously receive, a dividend on each outstanding share of Series A Preferred Stock in an amount at least equal to the greater of (i) the amount of the aggregate Accruing Dividends then accrued on such share of Series A Preferred Stock and not previously paid and (ii) (A) in the case of a dividend on Common Stock or any class or series that is convertible into Common Stock, that dividend per share of Series A Preferred Stock as would equal the product of (1) the dividend payable on each share of such class or series determined, if applicable, as if all shares of such class or series had been converted into Common Stock and (2) the number of shares of Common Stock issuable upon conversion of a share of Series A Preferred Stock, in each case calculated on the record date for determination of holders entitled to receive such dividend or (B) in the case of a dividend

on any class or series that is not convertible into Common Stock, at a rate per share of Series A Preferred Stock determined by (1) dividing the amount of the dividend payable on each share of such class or series of capital stock by the original issuance price of such class or series of capital stock (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to such class or series) and (2) multiplying such fraction by an amount equal to the Series A Original Issue Price; provided that if the Corporation declares, pays or sets aside, on the same date, a dividend on shares of more than one class or series of capital stock of the Corporation, the dividend payable to the holders of Series A Preferred Stock pursuant to this Section 2 shall be calculated based upon the dividend on the class or series of capital stock that would result in the highest Series A Preferred Stock dividend.

If the Corporation shall propose to take any action enumerated above in clauses (i) through (vi) of this Section 4(b) then, and in each such case, the Corporation shall give notice of such proposed action to each Holder of record appearing on the stock books of the Corporation as of the date of such notice at the address of said Holder shown therein. Such notice shall specify, inter alia (x) the proposed effective date of such action; (y) the date on which a record is to be taken for the purposes of such action, if applicable; and (z) the other material terms of such action. Such notice shall be given at least two (2) Business Days prior to the applicable date or effective date specified above. For the purposes of this Certificate of Designations, “Business Day” shall mean each day that is not a Saturday, Sunday or other day on which banking institutions in New York, New York are authorized or required by law to close. If at any time the Corporation shall cancel any of the proposed actions for which notice has been given under this Section 4(b) prior to the consummation thereof, the Corporation shall give prompt notice of such cancellation to each holder of record of the shares of Series A Preferred Stock appearing on the stock books of the Corporation as of the date of such notice at the address of said Holder shown therein. For the avoidance of doubt, if a holder of record of shares of Series A Preferred Stock does not respond to the aforementioned notice, such non-response shall in no way be deemed to constitute the written consent or affirmative vote of such Holder regarding any of the aforementioned actions in this Section 4(b) or described within such notice.

At any time that any Series A Preferred Stock is outstanding, the Corporation shall from time to time take all lawful action within its control to cause the authorized Capital Stock of the Corporation to include a number of authorized but unissued shares of Common Stock equal to the Conversion Ratio multiplied by the number of shares of outstanding Series A Preferred Stock.

The shares of Series A Preferred Stock shall be in uncertificated, book-entry form as permitted by the Amended and Restated Bylaws of the Corporation (the “Bylaws”) and the General Corporation Law. Within a reasonable time after the issuance or transfer of uncertificated shares, the Corporation shall send to the registered owner thereof any written notice as required by the General Corporation Law.

The shares of Series A Preferred Stock shall not have any powers, designations, preferences or relative, participating, optional, or other special rights, nor shall there be any qualifications, limitations or restrictions or any powers, designations, preferences or rights of such shares, other than as set forth herein or in the Certificate of Incorporation, or as may be provided by law.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER THE SECURITIES ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

REGISTRATIONS

2.1 Demand Registration.

(a) Request for Registration. Subject to the provisions of Section 2.1(d) and Section 2.4 hereof, at any time and from time to time on or after the date the Company closed the Transaction, each Holder (the “Demanding Holders”) may make a written demand for Registration of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand, a “Demand Registration”). The Company shall, within five (5) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall, subject to Section 3.4 hereof, effect within fifteen (15) days immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration. Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this Section 2.1(a) with respect to any or all Registrable Securities; provided, however, that a Registration shall not be counted for such purposes unless a Form S-1, Form S-3 or any other form of registration statement that may be available at such time has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Registration have been sold, in accordance with Section 3.1 of this Agreement.

(b) Effective Registration. Notwithstanding the provisions of Section 2.1(a) above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency, the Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and until, (a) such stop order or injunction is removed, rescinded or otherwise terminated, and (b) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; and provided, further, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated.

(c) Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten offering advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell, taken together with all other shares of Common Stock or other securities which the Company desires to sell and the shares of Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights held by other stockholders of the Company who desire to sell, exceeds the Maximum Number of Securities, then the Company shall include in such Registration:

(i) first, the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance with the number of shares that each such person has requested be included in such Registration, regardless of the number of shares held by each such person) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the shares of Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

(d) Demand Registration Withdrawal. A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest of the Requesting Holders (if any), pursuant to a Registration under Section 2.1(a) shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration.

2.2 Piggyback Registration.

(a) Piggyback Rights. If, at any time on or after the date the Company consummates the Transaction, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (a) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (b) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such Registration, a “Piggyback Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this Section 2.2(a) to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this Section 2.2(a) shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.

(b) Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of the shares of Common Stock that the Company desires to sell, taken together with (i) the shares of Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2(a) hereof, and (iii) the shares of Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(i) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2(a) hereof, pro rata based on the number of Registrable Securities that each Holder has requested be included in such Piggyback Registration and the aggregate number of Registrable Securities that the Holders have requested be included in such Piggyback Registration, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

(ii) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, the shares of Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2(a), pro rata based on the number of Registrable Securities that each Holder has requested be included in such Piggyback Registration and the aggregate number of Registrable Securities that the Holders have requested be included in such Piggyback Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the number of shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the number of shares of Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

(c) Piggyback Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration. The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement.

(d) Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.

2.3 Registrations on Form S-3. Any Holder of Registrable Securities may at any time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3 or any similar short form registration statement that may be available at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering. Within five (5) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a Registration on Form S-3, the Company shall register all or such portion of such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of any other Holder

or Holders joining in such request as are specified in the written notification given by such Holder or Holders; provided, however, that the Company shall not be obligated to effect any such Registration pursuant to this Section 2.3 if (i) a Form S-3 is not available for such offering; or (ii) the Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at an aggregate price to the public of less than $5.0 million.

2.4 Restrictions on Registration Rights. If (i) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to Section 2.1(a) and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective, or (ii) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration Statement. In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month period.

ARTICLE 3

COMPANY PROCEDURES

(g) advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

(h) notify the Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof; and

(i) otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders, in connection with such Registration.

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company; provided, however, and for the avoidance of doubt, the Company and each Holder shall be responsible for the expenses of their advisors, including their legal counsel. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and all reasonable fees and expenses of any legal counsel representing the Holders.

3.3 Suspension of Sales; Adverse Disclosure. Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until he, she or it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until he, she or it is advised in writing by the Company that the use of the Prospectus may be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are not yet audited or otherwise unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities. The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.3.

3.4 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings. The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of the Series A Preferred Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE 4

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

(a) The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

(b) In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

(c) Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or

controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

(e) If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall 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, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 4.1(e) shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1(a), 4.1(b) and 4.1(c) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1(e) were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1(e). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1(e) from any person who was not guilty of such fraudulent misrepresentation.

ARTICLE 5

(a) This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part.

(b) No Holder may assign or delegate such Holder’s rights, duties or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable Securities by such Holder to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this Agreement.

No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company.
