Such Investor covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with such Investor will engage, directly or indirectly, in any Transactions prior to the time the transactions contemplated by this Agreement are publicly disclosed. “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act and all types of direct and indirect stock pledges, forward sale contracts, options, puts, calls, short sales, swaps, derivatives and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker-dealers or foreign regulated brokers.

(i) Restricted Securities. The Investor understands that the Securities are characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances.

(j) Legends. It is understood that, except as provided in Section 4.1(b) of this Agreement, certificates evidencing such Securities may bear the legend set forth in Section 4.1(b).

(k) No Advertisement. Such Investor is not subscribing for Securities as a result of or subsequent to any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar, meeting or conference whose attendees have been invited by any general solicitation or general advertising.

(l) No Legal, Tax or Investment Advice. Such Investor understands that nothing in this Agreement or any other materials presented by or on behalf of the Company to the Investor in connection with the purchase of the Securities constitutes legal, tax or investment advice. Such Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities. Such Investor understands that the Agent has acted solely as the agent of the Company in this placement of the Securities and not to the Investor, and that the Agent makes no representation or warranty with regard to the merits of this transaction or as to the accuracy of any information such Investor may have received in connection therewith. Such Investor acknowledges that he has not relied on any information or advice furnished by or on behalf of the Agent.

(m) Investor is Not a Minor. If the Investor is a natural Person, such has reached the age of majority in the state in which such Investor resides. Such Investor has adequate means of providing for such Investor’s current financial needs and contingencies, is able to bear the substantial economic risks of an investment in the Securities for an indefinite period of time, has no need for liquidity in such investment and can afford a complete loss of such investment.

(n) Risks to Retirement Plans. If the Investor is a retirement plan or is investing on behalf of a retirement plan, such Investor acknowledges that an investment in the Securities poses additional risks, including the inability to use losses generated by an investment in the Securities to offset taxable income.

(o) Risk of Dilution. The Investor acknowledges that the Company will have the authority to issue shares of Common Stock, in excess of those being issued pursuant to this Agreement, and that the Company may issue additional shares of Common Stock from time to time. The issuance of additional shares of Common Stock may cause dilution of the existing shares of Common Stock and a decrease in the market price of such existing shares.

(p) Fees of Investor Counsel. The Investor further acknowledges that the Company has agreed (and the Company so agrees) to reimburse Montreux for fees and expenses of its legal counsel incurred in connection with this sale of Securities, which reimbursement shall not exceed $105,000, provided that the Company shall nevertheless reimburse the Investors for the amount of reasonable and documented regulatory and intellectual property counsel fees and expenses incurred notwithstanding the payment of such amount would mean the total costs borne by the Company would be in excess of the amounts described above.

(q) Broker Fees. The Investors have not entered into any agreement or arrangement that would entitle any broker or finder to compensation by the Company in connection with the sale of the Securities to such Investor.

(r) Foreign Investors. Each Investor who is not a US Person as defined in Regulation S under the Securities Act (“US Person”) represents and warrants as follows:

(i) (1) such Investor is not a US Person and is not acting for the account or benefit of a US Person, and (2) such Investor is purchasing the Securities in an offshore transaction pursuant to Regulation S;

(ii) such Investor understands that the Securities have not been and will not be registered under the Securities Act and may not be offered, resold, pledged or otherwise transferred by such Investor except (1) (w) in the United States to a person whom the seller reasonably believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A, (x) outside the United States in a transaction complying with the provisions of Rule 903 or Rule 904 of Regulation S, (y) pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if available), or (z) pursuant to an effective registration statement under the Securities Act, and (2) in accordance with any applicable securities laws of any state of the United States and other jurisdictions;

(iii) such Investor understands and agrees that, if in the future it decides to resell, pledge or otherwise transfer the Securities or any beneficial interests in any Securities prior to the date which is six months after the later of (1) the date when the Securities are first offered to persons (other than distributors) pursuant to Regulation S and (2) the date of the applicable Closing, it will do so only (x) in compliance with the restrictions set forth in Section D.1. hereof, (y) pursuant to an effective registration statement under the Securities Act, or (z) in accordance with the provisions of Rule 144A, Rule 144 (if available) or Regulation S, and in each of such cases in accordance with any applicable securities laws of any state of the United States;

(iv) such Investor agrees to, and each subsequent holder is required to, notify any transferee of the Securities from it of the resale restrictions referred to in paragraphs (ii) and (iii) above, if then applicable;

(v) such Investor acknowledges that, prior to any proposed transfer of the Securities other than pursuant to an effective registration statement, the transferee of the Securities may be required to provide certifications and other documentation relating to the non-US Person status of such transferee.

ARTICLE IV
OTHER AGREEMENTS OF THE PARTIES

4.1 Transfer Restrictions.

(a) The Investors covenant that the Securities will only be disposed of pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with any applicable state securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement or to the Company, or pursuant to Rule 144, the Company may require the transferor to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration under the Securities Act. Notwithstanding the foregoing, the Company hereby consents to and agrees to register on the books of the Company and with its Transfer Agent, without any such legal opinion, except to the extent that the Transfer Agent requests such legal opinion, any transfer of Securities by an Investor to an Affiliate of such Investor, provided that the transferee certifies to the Company that it is an “accredited investor” as defined in Rule 501(a) under the Securities Act and provided that such Affiliate does not request any removal of any existing legends on any certificate evidencing the Securities.

(b) The Investors agree to the imprinting, so long as is required by this Section 4.1(b), of the following legend on any certificate evidencing any of the Securities:

THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS.

Certificates evidencing Securities shall not be required to contain such legend or any other legend (i) while a registration statement (including the Registration Statement) covering the resale of the Securities is effective under the Securities Act, (ii) following any sale of such Securities pursuant to Rule 144 if the holder provides the Company with a legal opinion (and the documents upon which the legal opinion is based) reasonably acceptable to the Company to the effect that the Securities can be sold under Rule 144, (iii) if the holder provides the Company with a legal opinion (and the documents upon which the legal opinion is based) reasonably

acceptable to the Company to the effect that the Securities are eligible for sale under Rule 144 in a three-month period, or (iv) if the holder provides the Company with a legal opinion (and the documents upon which the legal opinion is based) reasonably acceptable to the Company to the effect that the legend is not required under applicable requirements of the Securities Act (including controlling judicial interpretations and pronouncements issued by the Staff of the SEC). The Company shall cause its counsel to issue the legal opinion included in the Transfer Agent Instructions to the Transfer Agent on the Effective Date. Following the Effective Date or at such earlier time as a legend is no longer required for certain Securities, the Company will no later than three Trading Days following the delivery by an Investor to the Company or the Transfer Agent of (i) a legended certificate representing such Securities, and (ii) an opinion of counsel to the extent required by Section 4.1(a), deliver or cause to be delivered to such Investor a certificate representing such Securities that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section.

If within three Trading Days after the Company’s receipt of a legended certificate and the other documents as specified in Clauses (i) and (ii) of the paragraph immediately above, the Company shall fail to issue and deliver to such Investor a certificate representing such Securities that is free from all restrictive and other legends, and if on or after such Trading Day the Investor purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Investor of shares of Common Stock that the Investor anticipated receiving from the Company without any restrictive legend (the “Covering Shares”), then the Company shall, within three Trading Days after the Investor’s request, pay cash to the Investor in an amount equal to the excess (if any) of the Investor’s total purchase price (including brokerage commissions, if any) for the Covering Shares, over the product of (A) the number of Covering Shares, times (B) the closing bid price on the date of delivery of such certificate and the other documents as specified in Clauses (i) and (ii) of the paragraph immediately above.

(c) The Company will not object to and shall permit (except as prohibited by law) an Investor to pledge or grant a security interest in some or all of the Securities in connection with a bona fide margin agreement or other loan or financing arrangement secured by the Securities, and if required under the terms of such agreement, loan or arrangement, the Company will not object to and shall permit (except as prohibited by law) such Investor to transfer pledged or secured Securities to the pledges or secured parties. Except as required by law, such a pledge or transfer would not be subject to approval of the Company, no legal opinion of the pledgee, secured party or pledgor shall be required in connection therewith, and no notice shall be required of such pledge. Each Investor acknowledges that the Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Securities or for any agreement, understanding or arrangement between any Investor and its pledgee or secured party. At the appropriate Investor’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of selling stockholders thereunder. Provided that the Company is in compliance with the terms of this Section 4.1(c), the Company’s indemnification obligations pursuant to Section 6.4 shall not extend to any Proceeding or Losses arising out of or related to this Section 4.1(c).

4.2 Furnishing of Information. Until the date that any Investor owning Common Shares, Call Shares or Warrant Shares may sell all of them under Rule 144 of the Securities Act (or any successor provision) in a three month period, the Company covenants to use its reasonable Best Efforts to timely file (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 the Exchange Act.

4.3 Integration. The Company shall not, and shall use its reasonable Best Efforts to ensure that no Affiliate thereof shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Investors or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market.

4.4 Reservation of Securities. The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount as may be required to fulfill its obligations to issue such Common Shares, Call Shares and Warrant Shares under the Transaction Documents. In the event that at any time the then authorized shares of Common Stock are insufficient for the Company to satisfy its obligations to issue such Common Shares, Call Shares and Warrant Shares under the Transaction Documents, the Company shall promptly take such actions as may be required to increase the number of authorized shares.

4.5 Securities Laws Disclosure; Publicity. The Company shall, on or before 8:30 a.m., New York time, on the first Trading Day following execution of this Agreement, issue a press release disclosing all material terms of the transactions contemplated hereby. On or before the Initial Closing Date, the Company shall file a Current Report on Form 8-K with the SEC (the “8-K Filing”) describing the terms of the transactions contemplated by the Transaction Documents and including as exhibits to such Current Report on Form 8-K the Transaction Documents (including the schedules and the names, and addresses of the Investors and the amount(s) of Securities respectively purchased) and the form of Warrants, Call Warrants, Second Call Warrants and Call Exercise Warrants, in the form required by the Exchange Act. Thereafter, the Company shall timely file any filings and notices required by the SEC or applicable law with respect to the transactions contemplated hereby and provide copies thereof to the Investors, as appropriate, promptly after filing. Except as herein provided, the Company shall not publicly disclose the name of any Investor, or include the name of any Investor in any press release without the prior written consent of such Investor, unless otherwise required by law. The Company shall not, and shall cause each of its officers, directors, employees and agents not to, provide any Investor with any material nonpublic information regarding the Company from and after the issuance of the above referenced press release without the express written consent of such Investor.

4.6 Use of Proceeds. The Company intends to use the net proceeds from the sale of the Securities for working capital and general corporate purposes. The Company also may use a portion of the net proceeds, currently intended for general corporate purposes, to acquire or invest in technologies, products or services that complement its business, although the Company has no present plans or commitments and is not currently engaged in any material negotiations with respect to these types of transactions. Pending these uses, the Company intends to invest the net proceeds from this offering in short-term, interest-bearing, investment-grade securities, or as otherwise pursuant to the Company’s customary investment policies.

4.7 Stockholders Meeting.

(a) Promptly following the Initial Closing Date, the Company shall take all action necessary to call a meeting of its stockholders (the “Stockholders Meeting”) for the purpose of seeking approval of the Company’s stockholders for the issuance of the Call Shares, the Call Exercise Warrants, the Second Closing Warrants, the Aggregate Incremental Warrant Shares and the Warrant Shares issuable upon exercise or otherwise pursuant to the Second Closing Warrants (the "Proposal”). In connection therewith, no later than twenty-one (21) calendar days after the Initial Closing Date, the Company shall prepare and file with the SEC a proxy statement for the Stockholders Meeting (together with any amendments thereof or supplements thereto and any other required proxy materials, the “Proxy Statement”). The Company shall use its reasonable Best Efforts to cause the Proxy Statement to be cleared by the SEC (“SEC Clearance”) and mailed to the stockholders of the Company as promptly as practicable after filing. The Company shall provide the Call Investors and their counsel with copies of any written comments or correspondence, and shall inform them of any oral comments or discussions, that the Company or its counsel may receive or have from time to time with the SEC or its staff with respect to the Proxy Statement promptly after such discussions, or the Company’s receipt of such comments or correspondence, and any written or oral responses thereto. The Company shall respond promptly to any comments made by the SEC with respect to the Proxy Statement. The Stockholders Meeting shall occur not later than January 31, 2009 (the “Stockholders Meeting Deadline”); provided however, that if, notwithstanding the exercise of the Company’s reasonable Best Efforts, the Company is unable to obtain SEC Clearance of the Proxy Statement by January 1, 2009, the Stockholders Meeting Deadline shall be automatically extended to February 28, 2009. Each Investor shall promptly furnish in writing to the Company such information relating to such Investor and its investment in the Company as the Company may reasonably request for inclusion in the Proxy Statement. The Company will comply with Section 14(a) of the Exchange Act and the rules promulgated thereunder in relation to any Proxy Statement to be sent to the stockholders of the Company in connection with the Stockholders Meeting, and the Proxy Statement shall not, on the date that the Proxy Statement (or any amendment thereof or supplement thereto) is first mailed to stockholders or at the time of the Stockholders Meeting, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein not false or misleading, or omit to state any material fact necessary to correct any statement in any earlier communication with respect to the solicitation of proxies or the Stockholders Meeting which has become false or misleading. If the Company should discover at any time prior to the Stockholders Meeting any event relating to the Company or any of its affiliates, officers or directors that is required to be set forth in a supplement or amendment to the Proxy Statement, in addition to the Company’s obligations under the Exchange Act, the Company will promptly inform the Investors thereof.

(b) Subject to their fiduciary obligations under applicable law (as determined in good faith by the Company’s Board of Directors after consultation with the Company’s outside counsel), the Company’s Board of Directors shall recommend to the Company’s stockholders that the stockholders vote in favor of the Proposal (the “Company Board Recommendation”) and shall take all commercially reasonable action (including, without limitation, the hiring of a proxy solicitation firm of nationally recognized standing) to solicit the approval of the stockholders for the Proposal unless the Board of Directors shall have modified, amended or withdrawn the Company Board Recommendation pursuant to the provisions of the immediately succeeding sentence. The Company covenants that the Board of Directors of the Company shall not modify, amend or withdraw the Company Board Recommendation unless the Board of Directors (after consultation with the Company’s outside counsel) shall determine in the good faith exercise of its business judgment that maintaining the Company Board Recommendation would violate its fiduciary duty to the Company’s stockholders. Whether or not the Company’s Board of Directors modifies, amends or withdraws the Company Board Recommendation pursuant to the immediately preceding sentence, the Company shall in accordance with applicable law and the provisions of its certificate of incorporation and bylaws, (i) take all action necessary to convene the Stockholders Meeting as promptly as practicable, but no later than the Stockholders Meeting Deadline, to consider and vote upon the approval of the Proposal and (ii) submit the Proposal at the Stockholders Meeting to the stockholders of the Company for their approval.

(c) Each Investor agrees that it shall not vote any shares of Common Stock held by such Investor against the Proposal at the Stockholders Meeting.

4.8 Lock-Up. Until the earlier of (a) the Stockholders Meeting Deadline and (b) the date on which the Stockholders Meeting is held (the “Lock-up Period”), no Investor shall directly or indirectly, sell, transfer, assign, pledge, hypothecate, tender, encumber or otherwise dispose of in any manner any of the Securities, or consent or agree to do any of the foregoing. Notwithstanding the foregoing, during the Lock-up Period an Investor may transfer any or all of the Securities as follows: (i) in the case of an Investor that is an entity, to any subsidiary, partner or member of such Investor, (ii) in the case of an Investor that is an individual, to such Investor’s spouse, ancestors, descendants or any trust for any of their benefits or to a charitable trust; provided, however, that in any such case, prior to and as a condition to the effectiveness of such transfer, (x) each person or entity to which any of such Securities or any interest in any of such Securities is or may be transferred has executed and delivered to the Company and the Call Investors a counterpart to this Agreement, which counterpart shall by such transferee’s execution thereof represent such transferee’s agreement to be bound by all of the terms and provisions of this Agreement, and (y) this Agreement becomes the legal, valid and binding agreement of such person, enforceable against such person in accordance with its terms, subject to the qualification, however, that enforcement of the rights and remedies created by this Agreement is subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general application related to or affecting creditors’ rights and to general equity principles. For purposes of this Section 4.8, the term “sell” or “transfer” or any derivatives thereof shall include, but not be limited to, (A) a sale, transfer or disposition of record or beneficial ownership, or both and (B) a short sale with respect to Common Stock or substantially identical property, entering into or acquiring an offsetting derivative contract with respect to Common Stock or substantially identical property, entering into or acquiring a futures or forward contract to deliver Common Stock or substantially identical property or entering into any transaction that has the same effect as any of the foregoing.

REGISTRATION RIGHTS

6.1 Registration Statement.

(a) As promptly as possible after the Initial Closing Date, and in any event on or prior to the Initial Filing Date, the Company shall prepare and file with the SEC a Registration Statement covering the resale of all of the Initial Closing Registrable Securities, for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be filed on Form S-1 and shall contain (except if otherwise directed by the Investors or requested by the SEC) the “Plan of Distribution” in substantially the form attached hereto as Exhibit D. The Company may convert the Registration Statement to one on Form S-3 at its option when and if it is eligible to do so.

As promptly as possible after the Second Closing Date, and in any event on or prior to the Second Filing Date, the Company shall prepare and file with the SEC a Registration Statement covering the resale of all of the Second Closing Registrable Securities, for an offering to be made on a continuous basis pursuant to Rule 415. The Registration Statement shall be filed on Form S-3 (unless the Company is not eligible at such time to register the Second Closing Registrable Securities on Form S-3, in which case it shall be on Form S-1) and shall contain (except if otherwise directed by the Call Investors or requested by the SEC) the “Plan of Distribution” in substantially the form attached hereto as Exhibit D.

(b) The Company shall use its commercially reasonable efforts to cause each Registration Statement to be declared effective by the SEC as promptly as possible after the filing thereof, but in any event prior to the applicable Required Effectiveness Date, and shall use its commercially reasonable efforts to keep each Registration Statement continuously effective under the Securities Act until the earlier of the date that all Securities covered by such Registration Statement have been sold or can be sold publicly under Rule 144 in a three month period (the “Effectiveness Period”); provided that, upon notification by the SEC that a Registration Statement will not be reviewed or is no longer subject to further review and comments, the Company shall request acceleration of such Registration Statement within five (5) Trading Days after receipt of such notice and request that it becomes effective on 4:00 p.m. New York City time on the Effective Date and file a prospectus supplement for any Registration Statement, whether or not required under Rule 424 (or otherwise), by 9:00 a.m. New York City time the day after the Effective Date.

(c) The Company shall notify the Investors in writing promptly (and in any event within five (5) Trading Days) after receiving notification from the SEC that a Registration Statement has been declared effective.

(d) Should an Event (as defined below) occur, then upon the occurrence of such Event, and on every monthly anniversary thereof until the applicable Event is cured, the Company shall pay to each Investor an amount in cash, as liquidated damages and not as a penalty, equal to one percent (1.0%) of (i) the number of Common Shares and Call Shares, as applicable, held by such Investor as of the date of such Event, multiplied by (ii) the purchase price paid by such Investor for such Common Shares and Call Shares, as applicable, then held;

provided, however, that the total amount of payments pursuant to this Section 6.1(d) shall not exceed, when aggregated with all such payments paid to all Investors, six percent (6%) of the aggregate purchase price set forth on Exhibit A hereto. The payments to which an Investor shall be entitled pursuant to this Section 6.1(d) are referred to herein as “Event Payments.” Any Event Payments payable pursuant to the terms hereof shall apply on a pro rated basis for any portion of a month prior to the cure of an Event.

For such purposes, each of the following shall constitute an “Event”:

(i) the Registration Statement is not filed on or prior to the Initial Filing Date or the Second Filing Date, as applicable, or is not declared effective on or prior to the applicable Required Effectiveness Date;

(ii) after the applicable Effective Date, an Investor is not permitted to sell Registrable Securities under the Registration Statement (or a subsequent Registration Statement filed in replacement thereof) due to the failure of the Company to maintain the effectiveness of such Registration Statement (other than black-out periods imposed by the Company to the extent provided for in Section 6.1(e) (the “Excluded Events”)) for ten (10) consecutive calendar days during the applicable Effectiveness Period or thirty (30) aggregate calendar days in any twelve (12) month period; or

(iii) except as a result of the Excluded Events, the Common Stock is not listed or quoted, or is suspended from trading, on an Eligible Market for a period of ten (10) consecutive Trading Days during the applicable Effectiveness Period or thirty (30) aggregate Trading Days in any twelve (12) month period.

(e) Notwithstanding anything in this Agreement to the contrary, after 60 consecutive Trading Days of continuous effectiveness of the initial Registration Statement filed and declared effective pursuant to this Agreement, the Company may, by written notice to the Investors, suspend sales under a Registration Statement after the applicable Effective Date thereof and/or require that the Investors immediately cease the sale of shares of Common Stock pursuant thereto and/or defer the filing of any subsequent Registration Statement if the Company is engaged in a material merger, acquisition or sale and the Board of Directors determines in good faith, by appropriate resolutions, that, as a result of such activity, (A) it would be materially detrimental to the Company (other than as relating solely to the price of the Common Stock) to maintain a Registration Statement at such time or (B) it is in the best interests of the Company to suspend sales under such registration at such time. Upon receipt of such notice, each Investor shall immediately discontinue any sales of Registrable Securities pursuant to such registration until such Investor is advised in writing by the Company that the current Prospectus or amended Prospectus, as applicable, may be used. In no event, however, shall this right be exercised to suspend sales beyond the period during which (in the good faith determination of the Company’s Board of Directors) the failure to require such suspension would be materially detrimental to the Company. The Company’s rights under this Section 6.1(e) may be exercised for a period of no more than 30 calendar days at a time and not more than two times in any twelve-month period, without such suspension being considered as part of an Event Payment determination. Immediately after the end of any suspension period under this Section 6.1(e), the Company shall take all necessary actions (including filing any required supplemental prospectus) to restore the effectiveness of the applicable Registration Statement and the ability of the Investors to publicly resell their Registrable Securities pursuant to such effective Registration Statement.

(f) The Company shall not, (i) from the date hereof until the Effective Date of the Registration Statement filed after the Initial Closing Date and (ii) from the date of the Call Notice until the Effective Date of the Registration Statement filed after the Second Closing Date, prepare and file with the SEC a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than any registration statement or post-effective amendment to a registration statement (or supplement thereto) relating to the Company’s employee benefit plans registered on Form S-8 and other than a registration statement registering only the Existing Registrable Shares.

(g) If at any time the staff of the SEC (the “Staff”) takes the position that the offering of some or all of the applicable Registrable Securities in a Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 or requires any Investor to be named as an “underwriter” (the “Staff Interpretation”), the Company shall use its reasonable Best Efforts to persuade the Staff that the offering contemplated by the Registration Statement is a valid secondary offering and not an offering “by or on behalf of the issuer” as defined in Rule 415 and that none of the Investors is an “underwriter”. In the event that, after the Company has used its reasonable Best Efforts to persuade the Staff that the Staff Interpretation should not apply to a Registration Statement, the Company cannot include all of the applicable Registrable Securities in a Registration Statement, then the Company shall include in such Registration Statement the maximum number of applicable Registrable Securities that can be included therein without causing the Registration Statement to be deemed to register a primary offering by the Company, with the number of applicable Registrable Securities included in the Registration Statement to be allocated among the Investors in proportion to the total applicable Registrable Securities held by each Investor on the date that the Registration Statement is filed. With respect to any applicable Registrable Securities that are not included in the Registration Statement (the “Excluded Securities”), the Company shall include the Excluded Securities in a subsequently filed second Registration Statement (the “Additional Registration Statement”) that is filed on the earliest possible date on which Excluded Securities can be included in the Additional Registration Statement without the Additional Registration Statement being deemed to register a primary offering of securities by the Company (the “Additional Filing Date”); provided that if the Company is advised by the SEC that the inclusion of all Excluded Securities in the Additional Registration Statement would cause the Additional Registration Statement to be deemed a registration of a primary offering by the Company, then such Additional Registration Statement shall include only the maximum number of Excluded Securities that could be included in such Registration Statement without it being deemed to be a registration for a primary offering by the Company. If all Excluded Securities cannot be registered on the Additional Registration Statement, then the Company will be obligated to file another Additional Registration Statement as soon as is permitted by the SEC to cover as many additional Excluded Securities as possible. The Company’s obligations under this Agreement with respect to the each Additional Registration Statement shall be the same as its obligations for the original Registration Statement, provided that the “Filing Date” for the each Additional Registration Statement shall be the applicable Additional Filing Date, and the “Effectiveness Date” for each Additional Registration Statement shall be delayed by the number of days that elapses between the Initial Filing Date or the Second Filing Date, as applicable, and the

applicable Additional Filing Date. In the event that an Investor sells or otherwise transfers any of such Investor’s Registrable Securities, each transferee shall be allocated a pro rata portion of the then-remaining number of Registrable Securities included in any Registration Statement for such transferor. To the extent permitted under applicable SEC rules, procedures, or practices, any shares of Common Stock included in a Registration Statement and which remain allocated to any Person which ceases to hold any Registrable Securities covered by such Registration Statement shall be allocated to the remaining Investors pro rata based on the number of Registrable Securities then held by such Holders which are covered by such Registration Statement. For purposes of this Section 6.1(g) only, the term “Registrable Securities” shall also include the Existing Registrable Shares sought to be included in the subject Registration Statement and the term “Investors” shall also include the Existing Registrable Shares Holders seeking inclusion of their Existing Registrable Shares in the subject Registration Statement.

6.2 Registration Procedures. In connection with the Company’s registration obligations hereunder, the Company shall:

(a) Not less than three Trading Days prior to the filing of a Registration Statement or any related Prospectus or any amendment or supplement thereto, furnish via email to those Investors who have supplied the Company with email addresses copies of all such documents proposed to be filed, which documents (other than any document that is incorporated or deemed to be incorporated by reference therein) will be subject to the review of such Investors. The Company shall reflect in each such document when so filed with the SEC such comments regarding the Investors and the plan of distribution as the Investors may reasonably and promptly propose no later than two Trading Days after the Investors have been so furnished with copies of such documents as aforesaid.

(b) (i) Subject to Section 6.1(e), prepare and file with the SEC such amendments, including post-effective amendments, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep the Registration Statement continuously effective, as to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the SEC such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424; and (iii) comply in all material respects with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by the Registration Statement during the applicable period in accordance with the intended methods of disposition by the Investors thereof set forth in the Registration Statement as so amended or in such Prospectus as so supplemented.

(c) Notify the Investors as promptly as reasonably possible, and if requested by the Investors, confirm such notice in writing no later than five Trading Days thereafter, of any of the following events: (i) the SEC notifies the Company whether there will be a “review” of any Registration Statement; (ii) any Registration Statement or any post-effective amendment is declared effective; (iii) the SEC issues any stop order suspending the effectiveness of any Registration Statement or initiates any Proceedings for that purpose; (iv) the Company receives notice of any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction, or the initiation or threat of any Proceeding for such

purpose; or (v) the financial statements included in any Registration Statement become ineligible for inclusion therein or any Registration Statement or Prospectus or other document contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Use its reasonable Best Efforts to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of any Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as possible.

(e) If requested by an Investor, provide such Investor and counsel to the lead investor, without charge, at least one conformed copy of each Registration Statement and each amendment thereto, including financial statements and schedules, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the SEC.

(f) Promptly deliver to each Investor, without charge, as many copies of the Prospectus or Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request. The Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Investors in connection with the offering and sale of the Registrable Securities covered by such Prospectus and any amendment or supplement thereto to the extent permitted by federal and state securities laws and regulations.

(g) (i) In the time and manner required by each Trading Market, prepare and file with such Trading Market one or more additional shares listing applications covering all of the Registrable Securities; (ii) take all steps necessary to cause such Common Shares to be approved for listing on each Trading Market as soon as possible thereafter; (iii) provide to Investor counsel evidence of such approval; and (iv) except as a result of the Excluded Events, use its reasonable Best Efforts to maintain the listing of such Common Shares on each such Trading Market or another Eligible Market for so long as any Common Shares or Warrant Shares are owned by the Investors.

(h) Prior to any public offering of Registrable Securities, to register or qualify or cooperate with the selling Investors in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Investor requests in writing, to keep each such registration or qualification (or exemption therefrom) effective for so long as required, but not to exceed the duration of the Effectiveness Period, and to do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by a Registration Statement; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(i) Cooperate with the Investors to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by this Agreement and under law, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Investors may reasonably request.

(j) Upon the occurrence of any event described in Section 6.2(c)(v), as promptly as reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither the Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(k) Cooperate with any reasonable due diligence investigation undertaken by the Investors in connection with the sale of Registrable Securities, including, without limitation, by making available documents and information; provided that the Company will not deliver or make available to any Investor material, nonpublic information unless such Investor requests in advance in writing to receive material, nonpublic information and agrees to keep such information confidential.

(l) Comply with all rules and regulations of the SEC applicable to the registration of the Securities.

(m) It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of any particular Investor or to make any Event Payments set forth in Section 6.1(c) to such Investor that such Investor furnish to the Company the information specified in Exhibits B-1, B-2 and B-3 hereto and such other information regarding itself, the Registrable Securities and other shares of Common Stock held by it and the intended method of disposition of the Registrable Securities held by it (if different from the Plan of Distribution set forth on Exhibit D hereto) as shall be reasonably required to effect the registration of such Registrable Securities and shall complete and execute such documents in connection with such registration as the Company may reasonably request.

(n) The Company shall comply with all applicable rules and regulations of the SEC under the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including any supplement or amendment thereof, with the SEC pursuant to Rule 424 under the Securities Act, promptly inform the Investors in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172 and, as a result thereof, the Investors are required to make available a Prospectus in connection with any disposition of Registrable Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder.

(o) From and after the Second Closing, all references in this Article to the Investors shall also refer to the Call Investors.

6.3 Registration Expenses. The Company shall pay all fees and expenses incident to the performance of or compliance with Article VI of this Agreement by the Company, including without limitation (a) all registration and filing fees and expenses, including without limitation those related to filings with the SEC, any Trading Market and in connection with applicable state securities or Blue Sky laws, (b) printing expenses (including without limitation expenses of printing certificates for Registrable Securities), (c) messenger, telephone and delivery expenses, (d) fees and disbursements of counsel for the Company, (e) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement, and (f) all listing fees to be paid by the Company to the Trading Market.

6.4 Indemnification

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Investor, the officers, directors, partners, members, agents and employees of each of them, each Person who controls any such Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all Losses, as incurred, arising out of or relating to (i) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (iii) any cause of action, suit or claim brought or made against such Indemnified Party (as defined in Section 6.4(c) below) by a third party (including for these purposes a derivative action brought on behalf of the Company), arising out of or resulting from execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, or (iv) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of Company prospectus or in any amendment or supplement thereto or in any Company preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding such Investor furnished in writing to the Company by such Investor for use therein, or to the extent that such information relates to such Investor or such Investor’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Investor expressly for use in the subject Registration Statement, or (B) with respect to any prospectus, if the untrue statement or omission of material fact contained in such prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented, if such corrected prospectus was timely made available by the Company to the Investor, and the Investor seeking indemnity hereunder was advised in writing not to use the incorrect prospectus prior to the use giving rise to Losses.

(b) Indemnification by Investors. Each Investor shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses (as determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising solely out of any untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto, or arising out of or relating to any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished by such Investor in writing to the Company specifically for inclusion in the subject Registration Statement or Prospectus or to the extent that (i) such untrue statements or omissions are based solely upon information regarding such Investor furnished to the Company by such Investor in writing expressly for use therein, or to the extent that such information relates to such Investor or such Investor’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Investor expressly for use in the subject Registration Statement (it being understood that the information provided by the Investor to the Company in Exhibits B-1, B-2 and B-3 and the Plan of Distribution set forth on Exhibit D, as the same may be modified by such Investor and other information provided by the Investor to the Company in or pursuant to the Transaction Documents constitutes information reviewed and expressly approved by such Investor in writing expressly for use in a Registration Statement), such Prospectus or such form of Prospectus or in any amendment or supplement thereto. In no event shall the liability of any selling Investor hereunder be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; or (ii) the Indemnifying Party shall have failed within 45 days of receiving notification of a Proceeding from an Indemnified Party to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (iii) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of separate counsel shall be at the expense of the Indemnifying Party). It being understood, however, that the Indemnifying Party shall not, in connection with any one such Proceeding (including separate Proceedings that have been or will be consolidated before a single judge) be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties, which firm shall be appointed by a majority of the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

All reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within 20 Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

(d) Contribution. If a claim for indemnification under Section 6.4(a) or (b) is unavailable to an Indemnified Party (by reason of law), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, 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 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 of a material fact, has been taken or made 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 any Losses shall be deemed to include, subject to the limitations set forth in Section 6.4(c), any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6.4(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 the immediately preceding paragraph. Notwithstanding the provisions of this Section 6.4(d), no Investor shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Investor from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

6.5 Dispositions. Each Investor agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement(s) and shall sell its Registrable Securities in accordance with the Plan of Distribution set forth in the Prospectus(es). Each Investor further agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Sections 6.2(c)(iii), (iv) or (v), such Investor will discontinue disposition of such Registrable Securities under the Registration Statement(s) until such Investor is advised in writing by the Company that the use of the Prospectus(es), or amended Prospectus(es), as applicable, may be used. The Company may provide appropriate stop orders to enforce the provisions of this paragraph.

6.6 No Piggyback on Registrations. Neither the Company nor any of its security holders (other than the Investors in such capacity pursuant hereto) may include securities of the Company in any Registration Statement other than the Registrable Securities and the Existing Registrable Shares.

6.7 Piggy-Back Registrations. If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the SEC a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, then the Company shall send to each Investor not then eligible to sell all of their Registrable Securities under Rule 144 in a three-month period, written notice of such determination and if, within ten days after receipt of such notice, any such Investor shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such Investor requests to be registered. Notwithstanding the foregoing, in the event that, in connection with any underwritten public offering, the managing

underwriter(s) thereof shall impose a limitation on the number of shares of Common Stock which may be included in the Registration Statement because, in such underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall be obligated to include in such Registration Statement only such limited portion of the Registrable Securities with respect to which such Investor has requested inclusion hereunder as the underwriter shall permit; provided, however, that (i) the Company shall not exclude any Registrable Securities unless the Company has first excluded all outstanding securities, the holders of which are not contractually entitled to inclusion of such securities in such Registration Statement or are not contractually entitled to pro rata inclusion with the Registrable Securities and (ii) after giving effect to the immediately preceding proviso, any such exclusion of Registrable Securities shall be made pro rata among the Investors seeking to include Registrable Securities and the holders of the Existing Registrable Securities or other securities having the contractual right to inclusion of their securities in such Registration Statement by reason of demand registration rights, in proportion to the number of Registrable Securities or other securities, as applicable, sought to be included by each such Investor or other holder. If an offering in connection with which an Investor is entitled to registration under this Section 6.7 is an underwritten offering, then each Investor whose Registrable Securities are included in such Registration Statement shall, unless otherwise agreed by the Company, offer and sell such Registrable Securities in an underwritten offering using the same underwriter or underwriters and, subject to the provisions of this Agreement, on the same terms and conditions as other shares of Common Stock included in such underwritten offering and shall enter into an underwriting agreement in a form and substance reasonably satisfactory to the Company and the underwriter or underwriters. Upon the effectiveness the Registration Statement for which piggy-back registration has been provided in this Section 6.7, the accrual of any Event Payments with respect to the Securities of an Investor that are included in such Registration Statement shall cease.

This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or email attachment, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or email-attached signature page were an original thereof.

7.13 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

7.14 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Investor exercises a right, election, demand or option owed to such Investor by the Company under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then, prior to the performance by the Company of the Company’s related obligation, such Investor may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

7.15 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company for any losses in connection therewith. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities.

7.16 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Investors and the Company will be entitled to seek specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation (other than in connection with any action for temporary restraining order) the defense that a remedy at law would be adequate.

7.17 Payment Set Aside. To the extent that the Company makes a payment or payments to any Investor hereunder or any Investor enforces or exercises its rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company by a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

7.18 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference in any Transaction Document to a number of shares or a price per share shall be amended to appropriately account for such event.

7.19 Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase Securities pursuant to this Agreement has been made by such Investor independently of any other Investor and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company which may have been made or given by any other Investor or by any agent or employee of any other Investor, and no Investor or any of its agents or employees shall have any liability to any other Investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Document. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no other Investor will be acting as agent of such Investor in connection with monitoring its investment hereunder. Each Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose.

1. The Company is a corporation, validly existing and in good corporate standing under the laws of the State of Delaware and has all requisite corporate power to operate its business as described in the SEC Reports and to execute and deliver the Transaction Documents and to perform its obligations thereunder.

2. The authorized capital stock of the Company consists of 135,000,000 shares of common stock, par value $0.001 per share (the “Common Stock”) and 27,000,000 shares of preferred stock, par value $0.001 per share.

The Warrant Shares issuable upon exercise of the Warrants and the Call Warrants have been duly authorized for issuance and reserved by the Company and, when issued and delivered against payment therefor in compliance with the Transaction Documents as in effect on the date hereof, will be validly issued, fully paid and non-assessable. The issuance of the Common Shares and the issuance of the Warrant Shares issuable upon exercise of the Warrants and the Call Warrants are not subject to preemptive rights pursuant to the General Corporation Law of the State of Delaware or the Company’s Certificate of Incorporation or Bylaws, as currently in effect.

4. The execution and delivery by the Company of the Transaction Documents, and the consummation by the Company of the transactions contemplated thereby, have been duly authorized by all necessary corporate and stockholder action on the part of the Company, subject to the requirement that the Company obtain stockholder approval of the issuance of the Call Shares, the Incremental Warrant Shares and the Second Closing Warrants (and the Warrant Shares issuable upon exercise thereof) prior to the Second Closing in order to comply with the requirements of the NASDAQ Stock Market. The Transaction Documents have been duly executed and delivered by the Company.

5. Each of the Transaction Documents constitutes the valid and binding obligation of the Company and is enforceable against the Company in accordance with its terms.

6. The execution and delivery by the Company of the Agreement and the Warrants and the Call Warrants, and the consummation by the Company of the transactions contemplated thereby, do not (a) violate the provisions of any federal law of the United States of America or the General Corporation Law of the State of Delaware applicable to the Company; (b) violate the provisions of the Company’s Certificate of Incorporation or By-laws; (c) violate any existing obligation of the Company under any judgment, decree, order or award of any court, governmental body or arbitrator specifically naming the Company and of which we are aware,

Exhibit C — 1

without any inquiry; or (d) with or without notice and/or the passage of time, conflict with or result in the material breach or termination of any material term or provision of, or constitute a material default under, or cause any acceleration of any material obligation under, or cause the creation of any material lien, charge or encumbrance upon the material properties or assets of the Company pursuant to any contract or instrument in the form included as an exhibit to any of the Company’s SEC Reports (the “Material Agreements”); except that we express no opinion as to state or foreign securities or blue sky laws or as to compliance with the antifraud provisions of federal, state or foreign securities laws.

7. Assuming (a) the accuracy of the representations made by each Investor in the Agreement; (b) that neither the Company, nor any person acting on behalf of the Company has offered or sold the Securities by any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D promulgated (the “Regulation D”) under the Securities Act; (c) that no offerings or sales of securities of the Company after the date hereof in a transaction can be “integrated” with any sales of the Securities; (d) that each person or entity that purchased securities of the Company directly from the Company or its agents and without registration between the date six months prior to the closing of the offering and the date of the Agreement was, as of the date of such purchase, an “accredited investor” as defined in Rule 501 of Regulation D; (e) the due performance by the Company of the covenants and agreements set forth in the Agreement; and (f) the compliance by the Investors with the offering and transfer procedures and restrictions set forth in the Agreement, the offer, sale and delivery of the Common Shares, Warrants and Call Warrants to the Investors at the Initial Closing under the circumstances contemplated by the Agreement do not require registration under Section 5 of the Securities Act, it being understood that we express no opinion as to any subsequent reoffer or resale of any of the Securities.

8. The Company is not, and immediately after the issuance and sale of the Common Shares, Warrants and Call Warrants will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

9. Except as set forth in the Agreement and except as have been obtained or made, no authorizations or consents of, or filings with, any federal, Delaware, governmental or governmental regulatory authority or entity or any Person under any Material Agreement are required to permit the Company to execute the Transaction Documents or the Warrants and Call Warrants, or to issue and sell the Common Shares and Warrants and Call Warrants (or are required under applicable state securities or “blue sky” laws), except that we express no opinion as to filings which may be required under foreign securities laws.

10. Assuming that at the time of such exercise the holders of the Warrants and Call Warrants are “accredited investors” as defined in Regulation D, the issuance of the Warrant Shares issuable upon exercise of the Warrants and the Call Warrants to the Investors pursuant to a Cashless Exercise (as defined therein) in accordance with the terms of the Warrants and the Call Warrants, assuming no commission or other remuneration is paid or given directly or indirectly for soliciting such Cashless Exercise, does not require registration under the Securities Act.

Exhibit C — 2

11. To our knowledge there is no action, suit or proceeding pending against the Company before or by any Florida or federal or, with respect to the Delaware General Corporation Law, Delaware court or arbitrator or any Florida or federal or, with respect to the Delaware General Corporation Law, Delaware governmental body, agency or official, which questions the validity or enforceability of any of the Transaction Documents.

Exhibit C-1 — 3

Exhibit D

Plan Of Distribution

The selling stockholders may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares:

•		ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
•		block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
•		purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
•		an exchange distribution in accordance with the rules of the applicable exchange;
•		privately negotiated transactions;
•		short sales;
•		broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
•		a combination of any such methods of sale; and
•		any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling stockholder. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

Exhibit D — 1

The selling stockholders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time under this prospectus after we have filed a supplement to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 supplementing or amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the shares of common stock from time to time under this prospectus after we have filed a supplement to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 supplementing or amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.

The selling stockholders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We are required to pay all fees and expenses incident to the registration of the shares of common stock. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

The selling stockholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares of common stock, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling stockholder. If we are notified by any selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file a supplement to this prospectus. If the selling stockholders use this prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.

The anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934 may apply to sales of our common stock and activities of the selling stockholders.

Attention:

Ladies and Gentlemen:

Reference is made to that certain Securities Purchase Agreement, dated as of October [  _____  ], 2008 (the “Agreement"), by and among MAKO Surgical Corp., a Delaware corporation (the “Company”), and the investors named on the Schedule of Investors attached thereto (collectively, the “Holders"), pursuant to which the Company is issuing to the Holders shares (the “Common Shares”) of Common Stock of the Company, par value $.001 per share (the “Common Stock”), Warrants (the “Warrants”), which are exercisable according to their terms into shares of Common Stock and pursuant to which the Company has been granted a right (the “Call Right”) to require certain of the Holders to purchase at a second subsequent closing additional shares of Common Stock (the “Call Shares”) and warrants to purchase additional shares of Common Stock (the “Second Closing Warrants”). In consideration of the grant of the Call Right, the Company also issued to certain Holders additional warrants to purchase shares of Common Stock (the “Call Warrants”) and will issue, if required pursuant to the Agreement, additional warrants (the “Call Exercise Warrants”) on the Second Closing Date (as defined in the Agreement).

This letter shall serve as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company at such time):

(i) to issue shares of Common Stock upon transfer or resale of the Common Shares and Call Shares; and

(ii) to issue shares of Common Stock upon the exercise of the Warrants, the Call Warrants, the Call Exercise Warrants and the Second Closing Warrants (the “Warrant Shares”) to or upon the order of a Holder from time to time upon delivery to you of a properly completed and duly executed Exercise Notice, in the form attached hereto as Exhibit I, which has been acknowledged by the Company as indicated by the signature of a duly authorized officer of the Company thereon.

You acknowledge and agree that so long as you have previously received (a) written confirmation from the Company’s legal counsel that either (i) a registration statement covering resales of the Common Shares, Call Shares and the Warrant Shares has been declared effective by the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the "Securities Act”) and that resales of the Common Shares, Call Shares and the Warrant Shares may be made thereunder, or (ii) sales of the Common Shares, Call Shares and the Warrant Shares may be made in conformity with Rule 144 under the Securities Act

Exhibit E — 1

(“Rule 144”), (b) if applicable, a copy of such registration statement, and (c) notice from legal counsel to the Company or any Holder that a transfer of Common Shares, Call Shares and/or Warrant Shares has been effected either pursuant to the registration statement (and a prospectus delivered to the transferee) or pursuant to Rule 144, then, unless otherwise required by law, within three (3) business days of your receipt of the notice referred to in (c), you shall issue the certificates representing the Common Shares, Call Shares and the Warrant Shares so sold to the transferees registered in the names of such transferees, and such certificates shall not bear any legend restricting transfer of the Common Shares, Call Shares and the Warrant Shares thereby and should not be subject to any stop-transfer restriction.

A form of written confirmation (to be used in connection with any sale) from the Company’s outside legal counsel that a registration statement covering resales of the Common Shares, Call Shares and the Warrant Shares has been declared effective by the SEC under the Securities Act is attached hereto as Exhibit II.

Please be advised that the Holders are relying upon this letter as an inducement to enter into the Agreement and, accordingly, each Holder is a third party beneficiary to these instructions.

Please execute this letter in the space indicated to acknowledge your agreement to act in accordance with these instructions. Should you have any questions concerning this matter, please contact me at ###-###-####.
