2. Registration Rights.

The Company covenants and agrees as follows:

2.1. Request for Registration.

(a) If the Company shall receive at any time after the earlier of (i) the fourth anniversary date of this Agreement or (ii) 180 days after the effective date of the Company’s IPO (other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or a SEC Rule 145 transaction), a written request from the Holders of forty percent (40%) of the Registrable Securities then outstanding that the Company file a registration statement under the Securities Act covering the registration of the Registrable Securities specified in such request, then the Company shall:

(i) within ten (10) days of the receipt thereof, give written notice of such request in accordance with Section 6.5 to all Holders (the “Demand Notice”);

(ii) as soon as practicable, and in any event within sixty (60) days of the receipt of such request, file a registration statement under the Securities Act covering all Registrable Securities which the Holders request to be registered within twenty (20) days of the mailing of the Demand Notice by the Company, subject to the limitations of subsection 2.1(b); and

4

(iii) use its best efforts to cause such registration statement to be declared effective by the SEC as soon as practicable.

(b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to subsection 2.1(a) and the Company shall include such information in the Demand Notice.  The underwriter will be selected by the Initiating Holders subject only to the reasonable approval of the Company.  In such event, the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein.  All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 2.3(e)) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting.  Notwithstanding any other provision of this Section 2.1, if the underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Initiating Holders shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among Holders of Registrable Securities issuable or issued upon conversion of the Preferred Stock (the “Preferred Registrable Securities”) pro rata on the basis of the number of such Preferred Registrable Securities requested to be registered by such Holders; provided, however, that the number of shares of Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting.  To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest 100 shares.

(c) The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 2.1:

(i) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, unless the Company is already subject to service in such jurisdiction and except as may be required under the Securities Act;

(ii) After the Company has effected two registrations pursuant to this Section 2.1 and such registrations have been declared or ordered effective;

(iii) If the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.11 below; or

(iv) Within ninety (90) days of the effective date of any other registration statement on Form S-1.

(d) Notwithstanding the foregoing, if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 2.1 a certificate signed by the

5

Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company (the “Board of Directors”) it would be materially detrimental to the Company and its stockholders for such registration statement to become effective or to remain effective as long as such registration statement would otherwise be required to remain effective because such action (x) would materially interfere with an acquisition, corporate reorganization or other similar transaction involving the Company, (y) would require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (z) would render the Company unable to comply with requirements under the Securities Act or Exchange Act, the Company shall have the right to defer taking action with respect to such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders; provided however, that the Company may not utilize this right more than once in any twelve-month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such ninety (90) day period other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction.

A registration statement shall not be counted until such time as such registration statement has been declared effective by the SEC (unless the Initiating Holders withdraw their request for such registration (other than as a result of information concerning the business or financial condition of the Company which is made known to the Initiating Holders after the date on which such registration was requested) and elect not to pay the registration expenses therefor pursuant to Section 2.5).  A registration statement shall not be counted if, as a result of an exercise of the underwriters’ cut-back provisions, fewer than 50% of the total number of Registrable Securities that Holders have requested to be included in such registration statement are actually included.

2.2. Company Registration.  If the Company proposes to register (including for this purpose a registration effected by the Company for stockholders other than the Holders) any of its stock or other securities under the Securities Act in connection with the public offering of such securities solely for cash (other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or an SEC Rule 145 transaction), the Company shall, at such time, promptly give each Holder written notice of such registration.  Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company in accordance with Section 6.5, the Company shall, subject to the provisions of Section 2.7, cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered.  The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.  The expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.6 hereof.

2.3. Obligations of the Company.  Whenever required under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible,

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities

6

registered thereunder, keep such registration statement effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the Registration Statement has been completed; provided, however, that (i) such 120-day period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of Common Stock (or other securities) of the Company; and (ii) in the case of any registration of Registrable Securities on Form S-3 which are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such 120-day period shall be extended as necessary to keep the registration statement effective until all such Registrable Securities are sold;

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(c) furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

(d) use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(e) in the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering (each Holder participating in such underwriting shall also enter into and perform its obligations under such agreement);

(f) cause all such Registrable Securities registered pursuant to this Agreement to be listed on a national securities exchange or trading system and each securities exchange and trading system on which similar securities issued by the Company are then listed;

(g) provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

(h) notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto 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 an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;

7

(i) use its best efforts to furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to this Section 2, on the date on which such Registrable Securities are sold to the underwriter, (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given by counsel to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a “comfort” letter dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any;

(j) promptly make available for inspection by the selling Holders, any managing underwriters participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith;

(k) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and

(l) after such registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or prospectus.

2.4. Furnish Information.  It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably required to effect the registration of such Holder’s Registrable Securities.

2.5. Expenses of Demand Registration.  All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Section 2.1, including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and the reasonable fees and disbursements of one counsel for the selling Holders shall be borne by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.1 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 2.1; provided further, however, that if at the time of such

8

withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness after learning of such information, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to Section 2.1.

2.6. Expenses of Company Registration.  The Company shall bear and pay all expenses incurred in connection with any registration, filing or qualification of Registrable Securities with respect to the registrations pursuant to Section 2.2 hereof for each Holder (which right may be assigned as provided in Section 2.12 hereof), including (without limitation) all registration, filing, and qualification fees, printers and accounting fees relating or apportionable thereto and the fees and disbursements of one counsel for the selling Holders selected by them, but excluding underwriting discounts and commissions relating to Registrable Securities.

2.7. Underwriting Requirements.  In connection with any offering involving an underwriting of shares of the Company’s capital stock pursuant to Section 2.2, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and its underwriters, and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company.  If the total number of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the amount of securities to be sold other than by the Company that the underwriters determine in their reasonable discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company determine in their sole discretion will not jeopardize the success of the offering.  In no event shall any Registrable Securities be excluded from such offering unless all other stockholders’ securities have been first excluded.  In the event that the underwriters determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be apportioned among selling Holders holding Preferred Registrable Securities pro rata on the basis of the number of such Preferred Registrable Securities requested to be registered by such selling Holders.  Notwithstanding the foregoing, in no event shall the amount of securities of the selling Holders included in the offering be reduced below thirty percent (30%) of the total amount of securities included in such offering, unless such offering is the Company’s IPO in which case the selling Holders may be excluded beyond this amount (down to zero) if the underwriters make the determination described above and no other stockholder’s securities are included in such offering.  For purposes of the preceding two sentences concerning apportionment, for any selling stockholder which is a Holder of Registrable Securities and which is an investment fund, partnership, limited liability company or corporation, the partners, members, retired partners, retired members, stockholders and Affiliates of such Holder, or the estates and family members of any such partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing Persons shall be deemed to be a single “selling Holder”, and any pro-rata reduction with respect to such “selling Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “selling Holder,” as defined in this sentence.

9

2.8. Delay of Registration.  No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2.

2.9. Indemnification.  In the event any Registrable Securities are included in a registration statement under this Section 2:

(a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers, directors, Affiliates and stockholders of each Holder, legal counsel and accountants for each Holder, any underwriter (as defined in the Securities Act) for such Holder and each Person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Violation and the Company will pay to each such Holder, underwriter, controlling Person or other aforementioned Person, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action as such expenses are incurred; provided, however, that the indemnity agreement contained in this subsection 2.9(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter, controlling Person or other aforementioned Person.

(b) To the extent permitted by law, each selling Holder will severally and not jointly indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each Person, if any, who controls the Company within the meaning of the Securities Act, legal counsel and accountants for the Company, any underwriter, any other Holder selling securities in such registration statement and any controlling Person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing Persons may become subject, under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay, any legal or other expenses reasonably incurred by any Person intended to be indemnified pursuant to this subsection 2.9(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 2.9(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, further, that, in no event shall any indemnity under this subsection 2.9(b) exceed the net proceeds from the offering received by such Holder, except in the case of fraud by such Holder.

(c) Promptly after receipt by an indemnified party under this Section 2.9 of notice of the commencement of any action (including any governmental action), such

10

indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.9, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding.  The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.9, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.9.

(d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case, in which either (i) any Holder exercising rights under this Agreement, or any controlling Person of any such Holder, makes a claim for indemnification pursuant to this Section 2.9 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 2.9 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling Holder or any such controlling Person in circumstances for which indemnification is provided under this Section 2.9, then, and in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations.  The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission; provided however, that, in any such case, (i) no such Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement, and (ii) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation; provided further, that in no event shall a Holder’s liability pursuant to this Section 2.9(d), when combined with the amounts paid or payable by such Holder pursuant to Section 2.9(b), exceed the net proceeds from the offering received by such Holder, except in the case of fraud by such Holder.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in

11

connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations of the Company and Holders under this Section 2.9 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 2, and otherwise and shall survive the termination of this Agreement.

2.10. Reports Under Exchange Act.  With a view to making available to the Holders the benefits of SEC Rule 144 promulgated under the Securities Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

(a) make and keep adequate current public information available, as those terms are understood and defined in SEC Rule 144, at all times after the effective date of the Company’s IPO so long as the Company is subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act;

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144, the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

2.11. Form S-3 Registration.  In case the Company shall receive from Holders of Registrable Securities then outstanding a written request or requests that the Company effect a registration on Form S-3 and any related qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company will:

(a) Promptly, but in any event within five (5) business days, give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and

(b) as soon as practicable, but in any event no later than forty-five (45) days following receipt of the written request requesting such registration, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within 15 days after receipt of such written notice from the Company; provided,

12

however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 2.11: (i) if Form S-3 is not then available for such offering by the Holders; (ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than $10,000,000; (iii) if the Company shall furnish to the Holders a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors, it would be materially detrimental to the Company and its stockholders for such Form S-3 Registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 2.11; provided, however, that the Company shall not utilize this right more than once in any twelve month period and provided further that the Company shall not register any securities for the account of itself or any other stockholder during such ninety day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Securities Act); (iv) if the Company has, within the three (3) month period preceding the date of such request, already effected one registration on Form S-3 for the Holders pursuant to this Section 2.11; (v) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance, unless the Company is already subject to service in such jurisdiction and except as may be required under the Securities Act; or (vi) during the period ending one hundred eighty (180) days after the effective date of a registration statement subject to Section 2.2 hereof.

(c) Subject to the foregoing, the Company shall file a registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders.  All expenses incurred in connection with a registration requested pursuant to Section 2.11, including (without limitation) all registration, filing, qualification, printer’s and accounting fees and the reasonable fees and disbursements of counsel for the selling Holder or Holders, and counsel for the Company, but excluding any underwriters’ discounts or commissions associated with Registrable Securities, shall be borne by the Company.  Registrations effected pursuant to this Section 2.11 shall not be counted as demands for registration or registrations effected pursuant to Section 2.1.

(d) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as part of their request made pursuant to this Section 2.11 and the Company shall include such information in the written notice referred to in Section 2.11(a).  The provisions of Section 2.1(b) shall be applicable to such request (with the substitution of Section 2.11 for references to Section 2.1).

2.12. Assignment of Registration Rights.  The rights to cause the Company to register Registrable Securities pursuant to this Section 2 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such securities that (i) is a subsidiary, Affiliate, parent, partner, member, limited partner, retired partner, retired member or stockholder of a Holder, (ii) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder, or (iii), after such assignment or transfer, holds at least five percent (5%) of the shares of

13

Registrable Securities originally purchased by such Holder (subject to appropriate adjustment for stock splits, stock dividends, combinations and other recapitalizations), provided: (a) the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; (b) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement, including without limitation the provisions of Section 2.14 below; and (c) such transfer or assignment shall be effective only if it was effected in compliance with applicable federal and state securities laws and immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the Securities Act.  For the purposes of determining the number of shares of Registrable Securities held by a transferee or assignee, the holdings of a transferee or assignee (i) that is a subsidiary, parent, partner, limited partner, retired partner, member, retired member or stockholder of a Holder; (ii) that is an Affiliate of the Holder, which means with respect to a limited liability company or a limited liability partnership, a fund or entity managed by the same manager or managing member or general partner or management company or by an entity controlling, controlled by, or under common control with such manager or managing member or general partner or management company, (iii) who is a Holder’s Immediate Family Member, or (iv) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member, shall be aggregated together with those of the assigning Holder, provided that all assignees and transferees who would not qualify individually for assignment of registration rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action under this Section 2.

2.13. Limitations on Subsequent Registration Rights.  From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of not less than fifty-five percent (55%) of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder (a) to include such securities in any registration unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the amount of the Registrable Securities of the Holders that are included or (b) to demand registration of any securities held by such holder or prospective holder.

2.14. “Market Stand-Off” Agreement.

(a) Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final prospectus relating to the Company’s IPO and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days, or such longer period, not to exceed eighteen (18) days after the expiration of the 180-day period, as the Company or such underwriters shall request in order to facilitate compliance with FINRA Rule 2711(f)) (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (whether such shares or any such securities are then owned by the Holder or are thereafter acquired), or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic

14

consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise.  The foregoing provisions of this Section 2.14 shall apply only to the Company’s IPO, shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall only be applicable to the Holders if all Key Holders, officers, directors and holders of greater than one percent (1%) of the Company’s securities on a fully-diluted basis enter into similar agreements.  The underwriters in connection with the Company’s IPO are intended third-party beneficiaries of this Section 2.14 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto.  Each Holder further agrees to execute such agreements as may be reasonably requested by the underwriters in the Company’s IPO that are consistent with this Section 2.14 or that are necessary to give further effect thereto.  Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply to all Holders subject to such agreements pro rata based on the number of shares subject to such agreements.

(b) In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities of each Holder (and the shares or securities of every other Person subject to the foregoing restriction) until the end of such period.

2.15. Termination of Registration Rights.

(a) No Holder shall be entitled to exercise any right provided for in this Section 2 after five (5) years following the consummation of the Company’s IPO.

(b) The rights set forth in this Section 2 shall terminate (i) upon a Deemed Liquidation Event, as such term is defined in the Restated Certificate other than a Deemed Liquidation Event pursuant to Article Fourth, Section C(3)(e)(i)(B) of the Restated Certificate and (ii) as to any Holder, when the Registrable Securities held by such Holder (together with any Affiliate of such Holder with whom such Holder must aggregate its sales under SEC Rule 144) could be sold without restriction under SEC Rule 144 within a ninety (90) day period.

3. Information and Inspection Rights.

3.1. Delivery of Financial Statements.  The Company shall deliver to each Major Investor, provided, that the Board of Directors has not reasonably determined that such Investor is, directly or indirectly, engaged in activity that is competitive with the business of the Company, provided, further, that the mere investment by a Major Investor that is a venture capital fund in other companies in the Company’s industry or participation on such company’s board of directors shall not, in and of itself, cause the Major Investor to be deemed, a competitor, of the Company:

(g) such other information relating to the financial condition, business, prospects or corporate affairs of the Company as the Investor or any assignee of the Investor may from time to time reasonably request, provided, however, that the Company shall not be obligated under this subsection (g) or any other subsection of Section 3.1 to (i) provide information which the Company reasonably deems in good faith to be a trade secret or similar confidential information (unless covered by an enforceable confidentiality agreement, in form acceptable to the

16

Company) or (ii) would adversely affect the attorney-client privilege between the Company and its counsel; and

(h) if for any period the Company shall have any subsidiary whose accounts are consolidated with those of the Company, then in respect of such period the financial statements delivered pursuant to the foregoing sections shall be the consolidated and consolidating financial statements of the Company and all such consolidated subsidiaries.

3.2. Inspection.  The Company shall permit each Major Investor, at such Major Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account and records and to discuss the Company’s affairs, finances and accounts with its officers, all at such reasonable times as may be reasonably requested by the Major Investor; provided, however, that the Company shall not be obligated pursuant to this Section 3.2 to provide access to any information which it reasonably considers to be a trade secret or similar confidential information or would adversely affect the attorney-client privilege between the Company and its counsel.

3.3. Termination of Information and Inspection Covenants.  The covenants set forth in Section 3.1 and Section 3.2 shall terminate as to the Major Investors and be of no further force or effect (i) immediately prior to the consummation of the Company’s IPO, (ii) when the Company first becomes subject to the periodic reporting requirements of Sections 12(g) or 15(d) of the Exchange Act or (iii) upon a Deemed Liquidation Event, as such term is defined in the Restated Certificate, whichever event shall first occur other than a Deemed Liquidation Event pursuant to Article Fourth, Section C(3)(e)(i)(B) of the Restated Certificate.

3.4. Confidentiality.

(a) Each Investor agrees that such Investor will keep confidential and will not disclose or divulge any confidential information obtained from the Company pursuant to the terms of this Agreement which the Company has identified in writing as being confidential, unless such confidential information (i) is known or becomes known to the public in general (other than as a result of a breach of this Section 3.4 by such Investor), (ii) is or has been independently developed or conceived by the Investor without use of the Company’s confidential information or (iii) is or has been made known or disclosed to the Investor by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that an Investor may disclose confidential information (a) to its attorneys, accountants, consultants, and other representatives of the Investor to the extent necessary to obtain their services in connection with monitoring its investment in the Company, (b) to any prospective investor of any Registrable Securities from such Investor as long as such prospective investor agrees in writing to be bound by the provisions of this Section 3.4, (c) to any Affiliate, partner, limited partner, member, stockholder, management company of such Investor or wholly owned subsidiary of such Investor in the ordinary course of business (or any employee or representative of any of the foregoing), or (d) as may otherwise be required by law or legal process, provided that the Investor takes reasonable steps to minimize the extent of any such required disclosure.  The Company acknowledges that at least some of the Investors are in the business of venture capital investing and therefore review the business plans and related proprietary information of many enterprises, including enterprises which may have products or services which compete directly or indirectly with those of the Company.  Nothing in this Agreement shall preclude or in any way restrict the

(b) By written notification received by the Company, within twenty (20) calendar days after mailing of the Offer Notice, each of the Holders, if such Holder is an “accredited investor” as such term is defined in Rule 501 of Regulation D promulgated under the Securities Act, may elect to purchase or obtain, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the number of shares of Common Stock issued or issuable upon conversion of the Preferred Stock then held by such Holder bears to the total number of shares of Common Stock of the Company then outstanding (assuming full conversion and exercise of all then-outstanding convertible or exercisable securities).  At the expiration of the twenty day period, the Company shall promptly, in writing, inform each Holder that elects to purchase all the shares available to it (each, a “Fully-Exercising Party”) of any other Holder’s failure to do likewise.  During the ten (10) day period commencing after receipt of such information, each Fully-Exercising Party shall be entitled to obtain that portion of the New Securities for which Holders were entitled to subscribe but which were not subscribed for by the Holders which is equal to the proportion that the number of shares of Common Stock issued or issuable upon conversion of Preferred Stock then held, by such Fully-Exercising Party bears to the total number of shares of Common Stock issued or issuable upon conversion of the Preferred Stock then held, by all Fully-Exercising Parties who wish to purchase such unsubscribed shares.

(c) If all New Securities referred to in the Offer Notice are not elected to be purchased or obtained as provided in Section 4.1(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in Section 4.1(b) hereof,

18

offer the remaining unsubscribed portion of such New Securities (collectively, the “Refused Securities”) to any Person or Persons at a price not less than, and upon terms no more favorable than those specified in the Offer Notice.  If the Company does not enter into an agreement for the sale of the New Securities within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless first reoffered to the Holders in accordance with this Section 4.1.

(d) The right of first offer in this Section 4.1 shall not be applicable to any offer or sale of New Securities which are Exempted Securities (as such term is defined in the Restated Certificate).

(e) The right of first offer set forth in this Section 4.1 may not be assigned or transferred except that (i) such right is assignable by each Holder to any Affiliate of such Holder, and (ii) such right is assignable by any Holder to any other Holder.

4.2. Termination.  The provisions of this Section 4 shall terminate upon the earlier of (a) the consummation of the Qualifying Public Offering (as such term is defined in the Restated Certificate) and (b) upon a Deemed Liquidation Event (as such term is defined in the Restated Certificate) other than a Deemed Liquidation Event pursuant to Article Fourth, Section C(3)(e)(i)(B) of the Restated Certificate.

5.3. Employee Vesting.  Unless approved by the Board of Directors, including the approval of the Preferred Directors, or a committee thereof, all future employees and consultants of the Company who shall purchase, or receive options to purchase, shares of the

22

which, individually or when aggregated with others would constitute the Sale of the Company.  The Company shall be obligated to share (and cause the Company’s counsel and investment bankers to share) such materials when distributed to the Company’s executives and/or any one or more of the other parties to such transaction(s).  In the event that Investor Counsel deems it appropriate, in its reasonable discretion, to enter into a joint defense agreement or other arrangement to enhance the ability of the parties to protect their communications and other reviewed materials under the attorney client privilege, the Company shall, and shall direct its counsel to, execute and deliver to Investor Counsel and its clients such an agreement in form and substance reasonably acceptable to Investor Counsel provided that such agreement does not compromise the attorney-client privilege. In the event that one or more of the other party or parties to such transactions require the clients of Investor Counsel to enter into a confidentiality agreement and/or joint defense agreement in order to receive such information, then the Company shall share whatever information can be shared without entry into such agreement and shall, at the same time, in good faith work expeditiously to enable Investor Counsel and its clients to negotiate and enter into the appropriate agreement(s) without undue burden to the clients of Investor Counsel.

5.20. Termination of Covenants.  The covenants set forth in this Section 5, except for Section 5.7, shall terminate and be of no further force or effect upon (a) the consummation of a Qualifying Public Offering (as defined in the Restated Certificate), or (b) upon a Deemed Liquidation Event (as defined in the Restated Certificate) other than a Deemed Liquidation Event pursuant to Article Fourth, Section C(3)(e)(i)(B) of the Restated Certificate, whichever event shall first occur.

6. Miscellaneous.

6.1. Successors and Assigns.  The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties.  Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

6.2. Governing Law.  This Agreement shall be governed by and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of Delaware, without regard to its principles of conflicts of laws.

6.3. Counterparts.  This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  Any such counterpart may be delivered via facsimile, electronic mail (including pdf) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

24

not execute such consent.  No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

6.8. Severability.  The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision.

6.9. Aggregation of Stock.  All shares of Registrable Securities held or acquired by Affiliates shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.

6.10. Entire Agreement.  This Agreement (including the Exhibits hereto, if any) constitutes the full and entire understanding and agreement between the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties are expressly canceled.

6.11. Transfers of Rights.  Each Investor and Key Holder hereby agrees that it will not, and may not, assign any of its rights and obligations hereunder, unless such rights and obligations are assigned by such Investor or Key Holder to (a) any Person to which Registrable Securities are transferred by such Investor or Key Holder, or (b) to any Affiliate of such Investor or Key Holder and, in each case, such transferee shall be deemed an “Investor,” or “Key Holder,” as applicable, for purposes of this Agreement; provided that such assignment of rights shall be contingent upon the transferee providing a written instrument to the Company notifying the Company of such transfer and assignment and agreeing in writing to be bound by the terms of this Agreement.

6.12. Termination of Prior Agreement.  Upon the execution and delivery of this Agreement by the Company and the Requisite Existing Holders, the Prior Agreement shall be hereby amended and restated in its entirety by this Agreement and shall be of no further force or effect.

6.13. Delays or Omissions.  No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring.  Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.  All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

6.14. Certain Actions following the IPO. Following the IPO, for so long as SC US GF Holdings, Ltd. and its Affiliates hold more than 5% of the outstanding Common Stock, the Company agrees (i) to include an individual (the “Sequoia Nominee”) nominated by SC US GF

25

Holdings, Ltd. in its slate of nominees for election as a member of the Board of Directors at each annual or special meeting of the stockholders of the Company at which directors are to be elected (the “Election Meetings”); (ii) to use reasonable best efforts to cause the election of the Sequoia Nominee to the Board of Directors at each of the Election Meetings (including recommending that the Company’s stockholders vote in favor of the election of the Sequoia Nominee and otherwise supporting the Sequoia Nominee for election in a manner no less rigorous and favorable than the manner in which the Company supports its other nominees; and (iii) to the extent legally permissible, if a Sequoia Nominee who is elected at any Election Meeting subsequently becomes unable to serve for any reason or is removed during the course of his or her term as a director, the Company will promptly appoint a replacement of the Sequoia Nominee submitted by SC US GF Holdings, Ltd. or its Affiliates to the Board of Directors until the following Election Meeting.

6.15. Excluded Opportunities.  The Company acknowledges that the Investors and their affiliates, members, equity holders, director representatives, partners, employees, agents and other related persons are engaged in the business of investing in private and public companies in a wide range of industries, including the industry segment in which the Company operates (the “Company Industry Segment”).  Accordingly, the Company and the Investors acknowledge and agree that a Covered Person shall:

(a) have no duty to the Company to refrain from participating as a director, investor or otherwise with respect to any company or other person or entity that is engaged in the Company Industry Segment or is otherwise competitive with the Company, and

(b) in connection with making investment decisions, to the fullest extent permitted by law, have no obligation of confidentiality or other duty to the Company to refrain from using any information, including, but not limited to, market trend and market data, which comes into such Covered Person’s possession, whether as a director, investor or otherwise.

For the purposes of this Section 6.15, “Covered Persons” shall have the meaning set forth in the Company’s current Certificate of Incorporation.

6.16. Additional Investors.  In the event that after the date of this Agreement, the Company issues shares of Capital Stock to any person who exercises stock options to purchase Series E-1 Preferred Stock, the Company shall cause such person to execute a counterpart signature page hereto as an Investor, and such person shall thereby be bound by, and subject to, all the terms and provisions of this Agreement applicable to an Investor.

EXHIBIT A

FORM OF NON-DISCLOSURE, NON-COMPETITION AND NON-SOLICITATION AGREEMENT

Non-Competition, Non-Solicitation and Confidentiality and Assignment Agreement

In consideration and as a condition of my employment or continued employment with Carbon Black, Inc. (together with its parents, subsidiaries and affiliates, the “Company”), I agree as follows:

1.             Proprietary Information.  I agree that all information, whether or not in writing, concerning the Company’s business, technology, business relationships or financial affairs which the Company has not released to the general public (collectively, “Proprietary Information”) is and will be the exclusive property of the Company.  Proprietary Information also includes information received in confidence by the Company from its customers or suppliers or other third parties.

2.             Recognition of Company’s Rights.  I will not, at any time, without the Company’s prior written permission, either during or after my employment, disclose any Proprietary Information to anyone outside of the Company, or use or permit to be used any Proprietary Information for any purpose other than the performance of my duties as an employee of the Company.  I will cooperate with the Company and use my best efforts to prevent the unauthorized disclosure of all Proprietary Information.  I will deliver to the Company all copies of Proprietary Information in my possession or control upon the earlier of a request by the Company or termination of my employment.

3.             Rights of Others.  I understand that the Company is now and may hereafter be subject to non-disclosure or confidentiality agreements with third persons which require the Company to protect or refrain from use of proprietary information.  I agree to be bound by the terms of such agreements in the event I have access to such proprietary information.

4.             Commitment to Company; Avoidance of Conflict of Interest.  While an employee of the Company, I will devote my full-time efforts to the Company’s business and I will not engage in any other business activity that conflicts with my duties to the Company.  I will advise the president of the Company or his or her nominee at such time as any activity of either the Company or another business presents me with a conflict of interest or the appearance of a conflict of interest as an employee of the Company.  I will take whatever action is requested of me by the Company to resolve any conflict or appearance of conflict which it finds to exist.

5.             Developments.  I will make full and prompt disclosure to the Company of all inventions, discoveries, designs, developments, methods, modifications, improvements, processes, algorithms, databases, computer programs, formulae, techniques, trade secrets, graphics or images, audio or visual works, and other works of authorship (collectively “Developments”), whether or not patentable or copyrightable, that are created, made, conceived or reduced to practice by me (alone or jointly with others) or under my direction during the period of my employment.  I acknowledge that all work performed by me is on a “work for hire” basis, and I hereby do assign and transfer and, to the extent any such assignment cannot be made at present, will assign and transfer, to the Company and its successors and assigns all my right, title and interest in all Developments that (a) relate to the business of the Company or any customer of or supplier to the Company or any of the products or services being researched, developed, manufactured or sold by the Company or which may be used with such products or services; or (b) result from tasks assigned to me by the Company; or (c) result from the use of premises or personal property (whether tangible or intangible) owned, leased or contracted for by the Company (“Company-Related Developments”), and all related patents, patent applications, trademarks and trademark applications, copyrights and copyright applications, and other intellectual property rights in all countries and territories worldwide and under any international conventions (“Intellectual Property Rights”).

To preclude any possible uncertainty, I have set forth on Exhibit A attached hereto a complete list of Developments that I have, alone or jointly with others, conceived, developed or reduced to practice prior to the commencement of my employment with the Company that I consider to be my property or the

property of third parties and that I wish to have excluded from the scope of this Agreement (“Prior Inventions”).  If disclosure of any such Prior Invention would cause me to violate any prior confidentiality agreement, I understand that I am not to list such Prior Inventions in Exhibit A but am only to disclose a cursory name for each such invention, a listing of the party(ies) to whom it belongs and the fact that full disclosure as to such inventions has not been made for that reason.  If, in the course of my employment with the Company, I incorporate a Prior Invention into a Company product, process or machine or other work done for the Company, I hereby grant to the Company a nonexclusive, royalty-free, paid-up, irrevocable, worldwide license (with the full right to sublicense) to make, have made, modify, use, sell, offer for sale and import such Prior Invention.  Notwithstanding the foregoing, I will not incorporate, or permit to be incorporated, Prior Inventions in any Company-Related Development without the Company’s prior written consent.

This Agreement does not obligate me to assign to the Company any Development which, in the sole judgment of the Company, reasonably exercised, is developed entirely on my own time and does not relate to the business efforts or research and development efforts in which, during the period of my employment, the Company actually is engaged or reasonably would be engaged, and does not result from the use of premises or equipment owned or leased by the Company.  However, I will also promptly disclose to the Company any such Developments for the purpose of determining whether they qualify for such exclusion.  I understand that to the extent this Agreement is required to be construed in accordance with the laws of any state which precludes a requirement in an employee agreement to assign certain classes of inventions made by an employee, this paragraph 5 will be interpreted not to apply to any invention which a court rules and/or the Company agrees falls within such classes.  I also hereby waive all claims to any moral rights or other special rights which I may have or accrue in any Company-Related  Developments.

6.             Documents and Other Materials.  I will keep and maintain adequate and current records of all Proprietary Information and Company-Related Developments developed by me during my employment, which records will be available to and remain the sole property of the Company at all times.

All files, letters, notes, memoranda, reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification sheets, models, prototypes, or other written, photographic or other tangible material containing Proprietary Information, whether created by me or others, which come into my custody or possession, are the exclusive property of the Company to be used by me only in the performance of my duties for the Company.  Any property situated on the Company’s premises and owned by the Company, including without limitation computers, disks and other storage media, filing cabinets or other work areas, is subject to inspection by the Company at any time with or without notice.  In the event of the termination of my employment for any reason, I will deliver to the Company all files, letters, notes, memoranda, reports, records, data, sketches, drawings, notebooks, layouts, charts, quotations and proposals, specification sheets, models, prototypes, or other written, photographic or other tangible material containing Proprietary Information, and other materials of any nature pertaining to the Proprietary Information of the Company and to my work, and will not take or keep in my possession any of the foregoing or any copies.

7.             Enforcement of Intellectual Property Rights.  I will cooperate fully with the Company, both during and after my employment with the Company, with respect to the procurement, maintenance and enforcement of Intellectual Property Rights in Company-Related Developments.  I will sign, both during and after the term of this Agreement, all papers, including without limitation copyright applications, patent applications, declarations, oaths, assignments of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to protect its rights and interests in any Company-Related Development.  If the Company is unable, after reasonable effort, to secure my signature on any such papers, I hereby irrevocably designate and appoint each officer of the Company as my agent and attorney-in-fact to execute any such papers on my behalf, and to take any and all actions as the Company may deem necessary or desirable in order to protect its rights and interests in any Company-Related Development.

8.             Non-Competition and Non-Solicitation.  In order to protect the Company’s Proprietary Information and good will, during my employment with the Company and for a period of twelve (12) months following the termination of my employment for any reason (the “Restricted Period”), I will not directly or indirectly, whether as owner, partner, shareholder, director, manager, consultant, agent, employee, co-venturer or otherwise, engage, participate or invest in any business activity

2

anywhere in the world that develops, manufactures or markets any products, or performs any services, that are competitive with the products or services of the Company, or products or services that the Company or its affiliates, has under development or that are the subject of active planning at any time during my employment, provided that this shall not prohibit any possible investment in publicly traded stock of a company representing less than one percent of the stock of such company.  In addition, during the Restricted Period, I will not, directly or indirectly, in any manner, other than for the benefit of the Company, (a) call upon, solicit, divert, take away, accept or conduct any business from or with any of the customers or prospective customers of the Company or any of its suppliers, and/or (b) solicit, entice, attempt to persuade any other employee or consultant of the Company to leave the Company for any reason or otherwise participate in or facilitate the hire, directly or through another entity, of any person who is employed or engaged by the Company or who was employed or engaged by the Company within six months of any attempt to hire such person.  I acknowledge and agree that if I violate any of the provisions of this paragraph 8, the running of the Restricted Period will be extended by the time during which I engage in such violation(s).

9.             Prior Agreements.  I hereby represent that, except as I have fully disclosed previously in writing to the Company, I am not bound by the terms of any agreement with any previous employer or other party to refrain from using or disclosing any trade secret or confidential or proprietary information in the course of my employment with the Company or to refrain from competing, directly or indirectly, with the business of such previous employer or any other party.  I further represent that my performance of all the terms of this Agreement as an employee of the Company does not and will not breach any agreement to keep in confidence proprietary information, knowledge or data acquired by me in confidence or in trust prior to my employment with the Company. I will not disclose to the Company or induce the Company to use any confidential or proprietary information or material belonging to any previous employer or others.

10.          Remedies Upon Breach.   I understand that the restrictions contained in this Agreement are necessary for the protection of the business and goodwill of the Company and I consider them to be reasonable for such purpose.  Any breach of this Agreement is likely to cause the Company substantial and irrevocable damage and therefore, in the event of such breach, the Company, in addition to such other remedies which may be available, will be entitled to specific performance and other injunctive relief, without the posting of a bond.  If I violate this Agreement, in addition to all other remedies available to the Company at law, in equity, and under contract, I agree that I am obligated to pay all the Company’s costs of enforcement of this Agreement, including attorneys’ fees and expenses.

11.          No Employment Obligation.  I understand that this Agreement does not create an obligation on the Company or any other person to continue my employment.  I acknowledge that, unless otherwise agreed in a formal written employment agreement signed on behalf of the Company by an authorized officer, my employment with the Company is at will and therefore may be terminated by the Company or me at any time and for any reason, with or without cause.

12.          Survival and Assignment by the Company.  I understand that my obligations under this Agreement will continue in accordance with its express terms regardless of any changes in my title, position, duties, salary, compensation or benefits or other terms and conditions of employment. I further understand that my obligations under this Agreement will continue following the termination of my employment regardless of the manner of such termination and will be binding upon my heirs, executors and administrators.  The Company will have the right to assign this Agreement to its affiliates, successors and assigns.  I expressly consent to be bound by the provisions of this Agreement for the benefit of the Company or any parent, subsidiary or affiliate to whose employ I may be transferred without the necessity that this Agreement be resigned at the time of such transfer.

13.          Severability.  In case any provisions (or portions thereof) contained in this Agreement shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.  If, moreover, any one or more of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable law as it shall then appear.

14.          Interpretation.  This Agreement will be deemed to be made and entered into in the State of Massachusetts, and will in all respects be interpreted, enforced and governed under the laws of the State of Massachusetts.  I hereby agree to consent to personal jurisdiction of the state and federal courts in the State of Massachusetts for purposes of enforcing this Agreement, and waive any objection that I might have to personal jurisdiction or venue in those courts.

15.          Other Agreements.  This Agreement shall supplement, and shall not limit or be limited by any other restrictive covenant agreement to which the Company (or any its subsidiaries or affiliates) and I are parties, including, without limitation, any noncompetition, nonsolicitation and/or assignment of inventions agreement I previously entered into with the Company.
