2.1 Required Registrations.

(a) At any time after the earlier of (i) three years after the date of this Agreement or (ii) six months after the closing of the Initial Public Offering, a Purchaser or Purchasers holding in the aggregate at least 50.1% of the Registrable Shares then outstanding may request, in writing, that the Company effect the registration on Form S-1 (or any successor form) of Registrable Shares owned by such Purchaser or Purchasers having an aggregate value of at least $5,000,000 (based on the market price or fair value on the date of such request).

 

-5-


(b) At any time after the Company becomes eligible to file a Registration Statement on Form S-3 (or any successor form relating to secondary offerings), a Purchaser or Purchasers holding in the aggregate at least 50.1% of the Registrable Shares may request, in writing, that the Company effect the registration on Form S-3 (or such successor form), of Registrable Shares having an aggregate value of at least $3,000,000 (based on the public market price on the date of such request).

(c) Upon receipt of any request for registration pursuant to this Section 2, the Company shall promptly give written notice of such proposed registration to all other Purchasers. Such Purchasers shall have the right, by giving written notice to the Company within 30 days after the Company provides its notice, to elect to have included in such registration such of their Registrable Shares as such Purchasers may request in such notice of election, subject in the case of an underwritten offering to the terms of Section 2.1(d). Thereupon, the Company shall, as expeditiously as possible, use its best efforts to effect the registration on an appropriate registration form of all Registrable Shares which the Company has been requested to so register; provided, however, that in the case of a registration requested under Section 2.1(b), the Company will only be obligated to effect such registration on Form S-3 (or any successor form).

(d) If the Initiating Holders intend to distribute the Registrable Shares covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 2.1(a) or (b), as the case may be, and the Company shall include such information in its written notice referred to in Section 2.1(c). In such event, (i) the right of any other Purchaser to include its Registrable Shares in such registration pursuant to Section 2.1(a) or (b), as the case may be, shall be conditioned upon such other Purchaser’s participation in such underwriting on the terms set forth herein, and (ii) all Purchasers including Registrable Shares in such registration shall enter into an underwriting agreement upon customary terms with the underwriter or underwriters managing the offering; provided that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of the Purchasers materially greater than the obligations of the Purchasers pursuant to Section 2.5 as with respect to the persons indemnified pursuant to Section 2.5. The Initiating Holders shall have the right to select the managing underwriter(s) for any underwritten offering requested pursuant to Section 2.1(a) or (b), subject to the approval of the Company, which approval will not be unreasonably withheld, conditioned or delayed. If any Purchaser who has requested inclusion of its Registrable Shares in such registration as provided above disapproves of the terms of the underwriting, such Purchaser may elect, by written notice to the Company, to withdraw its Registrable Shares from such Registration Statement and underwriting. If the managing underwriter advises the Company in writing that marketing factors require a limitation on the number of shares to be underwritten and after reducing any other shares included in such registration to zero, including any Company shares, the number of Purchaser Registrable Shares to be included in the Registration Statement and underwriting shall be allocated among all Purchasers requesting registration in proportion, as nearly as practicable, to the respective number of Registrable Shares held by them on the date of the request for registration made by

 

-6-


the Initiating Holders pursuant to Section 2.1(a) or (b), as the case may be. If any Purchaser would thus be entitled to include more Registrable Shares than such Purchaser requested to be registered, the excess shall be allocated among other requesting Purchasers pro rata in the manner described in the preceding sentence.

(e) The Company shall not be required to effect (nor pay for) more than two registrations pursuant to Section 2.1(a) or more than two registrations within any 12-month period pursuant to Section 2.1(b) (in each case, counting for these purposes only registrations which have been declared or ordered effective, remain in effect and no stop order is then in effect or pursuant to which the distribution described therein has been completed). In addition, the Company shall not be required to effect any registration within six months after the effective date of the Registration Statement relating to the Initial Public Offering. For purposes of this Section 2.1(e), a Registration Statement shall not be counted until such time as such Registration Statement has been declared effective by the Commission (unless the Initiating Holders withdraw their request for such registration and elect not to pay the Registration Expenses therefor pursuant to Section 2.4 (other than as a result of information concerning the business or financial condition of the Company which is made known to the Purchasers after the date on which such registration was requested)). For purposes of this Section 2.1(e), a Registration Statement shall not be counted if, as a result of an exercise of the underwriter’s cut-back provisions, less than 50% of the total number of Registrable Shares that Purchasers have requested to be included in such Registration Statement are so included.

(f) If at the time of any request to register Registrable Shares by Initiating Holders pursuant to this Section 2.1, the Company is engaged or has plans to engage in a registered public offering or is engaged in any other activity which, in the good faith determination of the Company’s Board of Directors, would be adversely affected by the requested registration, then the Company may at its option direct that such request be delayed for a period not in excess of 30 days from the date of such request, such right to delay a request to be exercised by the Company not more than once in any 12-month period.

2.2 Incidental Registration.

(a) Whenever the Company proposes to file a Registration Statement (other than a Registration Statement filed pursuant to Section 2.1) at any time and from time to time, it will, prior to such filing, give written notice to all Purchasers of its intention to do so; provided, that no such notice need be given if no Registrable Shares are to be included therein as a result of a written notice from the managing underwriter pursuant to Section 2.2(b). Upon the written request of a Purchaser or Purchasers given within 20 days after the Company provides such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use its best efforts to cause all Registrable Shares which the Company has been requested by such Purchaser or Purchasers to register to be registered under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Purchaser or Purchasers; provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this Section 2.2 without obligation to any Purchaser.

 

-7-


(b) If the registration for which the Company gives notice pursuant to Section 2.2(a) is a registered public offering involving an underwriting, the Company shall so advise the Purchasers as a part of the written notice given pursuant to Section 2.2(a). In such event, (i) the right of any Purchaser to include its Registrable Shares in such registration pursuant to this Section 2.2 shall be conditioned upon such Purchaser’s participation in such underwriting on the terms set forth herein and (ii) all Purchasers including Registrable Shares in such registration shall enter into an underwriting agreement upon customary terms with the underwriter or underwriters selected for the underwriting by the Company; provided that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of Purchasers materially greater or different than the obligations of the Purchasers pursuant to Section 2.5. If any Purchaser who has requested inclusion of its Registrable Shares in such registration as provided above disapproves of the terms of the underwriting, such person may elect, by written notice to the Company, to withdraw its shares from such Registration Statement and underwriting. If the managing underwriter advises the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the shares held by (1) Other Holders and by holders of securities of the Company other than the Purchasers and Other Holders shall be excluded from such Registration Statement and underwriting to the extent deemed advisable by the managing underwriter, and (2) if a further reduction of the number of shares is required, the number of shares that may be included in such Registration Statement and underwriting shall be allocated among all Purchasers requesting registration in proportion, as nearly as practicable, to the respective number of shares of Common Stock (on an as-converted basis) held by them on the date the Company gives the notice specified in Section 2.2(a); provided, that, unless such registration is in connection with the Company’s Initial Public Offering, the number of Registrable Shares permitted to be included therein shall in any event be at least 30% of the securities included therein. If any Purchaser or Other Holder would thus be entitled to include more shares than such holder requested to be registered, the excess shall be allocated among other requesting Purchasers and Other Holders pro rata in the manner described in the preceding sentence.

2.3 Registration Procedures.

(a) If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the registration of any Registrable Shares under the Securities Act, the Company shall:

(i) prepare and file with the Commission a Registration Statement with respect to such Registrable Shares and use its best efforts to cause that Registration Statement to become effective as soon as possible;

(ii) to the extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) (a “WKSI”) at the time any request for registration is submitted to the Company in accordance with Section 2.1, (i) if so requested, file an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “automatic shelf registration statement”) to effect such registration, and (ii) remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such automatic shelf registration statement is required to remain effective in accordance with this Agreement;

 

-8-


(iii) if at any time when the Company is required to re-evaluate its WKSI status for purposes of an automatic shelf registration statement used to effect a request for registration in accordance with Section 2.3 (i) the Company determines that it is not a WKSI, (ii) the registration statement is required to be kept effective in accordance with this Agreement, and (iii) the registration rights of the applicable Holders have not terminated, promptly amend the registration statement onto a form the Company is then eligible to use or file a new registration statement on such form, and keep such registration statement effective in accordance with the requirements otherwise applicable under this Agreement;

(iv) if (i) a registration made pursuant to a shelf registration statement is required to be kept effective in accordance with this Agreement after the third anniversary of the initial effective date of the shelf registration statement and (ii) the registration rights of the applicable Holders have not terminated, file a new registration statement with respect to any unsold Registrable Securities subject to the original request for registration prior to the end of the three year period after the initial effective date of the shelf registration statement, and keep such registration statement effective in accordance with the requirements otherwise applicable under this Agreement;

(v) as expeditiously as possible prepare and file with the Commission any amendments and supplements to the Registration Statement and the prospectus included in the Registration Statement as may be necessary to comply with the provisions of the Securities Act (including the anti-fraud provisions thereof) and to keep the Registration Statement effective for 12 months from the effective date or such lesser period until all such Registrable Shares are sold;

(vi) as expeditiously as possible furnish to each Selling Stockholder such reasonable numbers of copies of the Prospectus, including any preliminary Prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Selling Stockholder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Shares owned by such Selling Stockholder;

(vii) as expeditiously as possible use its commercially reasonable efforts to register or qualify the Registrable Shares covered by the Registration Statement under the securities or Blue Sky laws of such states as the Selling Stockholders shall reasonably request, and do any and all other acts and things that may be necessary or desirable to enable the Selling Stockholders to consummate the public sale or other disposition in such states of the Registrable Shares owned by the Selling Stockholders; provided, however, that the Company shall not be required in connection with this paragraph (iv) to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction or to amend its Certificate of Incorporation or By-laws in a manner that the Board of Directors of the Company determines is inadvisable;

 

-9-


(viii) as expeditiously as possible, cause all such Registrable Shares to be listed on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed;

(ix) promptly provide a transfer agent, registrar and CUSIP number for all such Registrable Shares not later than the effective date of such Registration Statement;

(x) promptly make available for inspection by the Selling Stockholders, any managing underwriter 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 Stockholders, 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 connection with such Registration Statement;

(xi) notify each Selling Stockholder, promptly after it shall receive notice thereof, of the time when such Registration Statement has become effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed;

(xii) as expeditiously as possible following the effectiveness of such Registration Statement, notify each seller of such Registrable Shares of any request by the Commission for the amending or supplementing of such Registration Statement or Prospectus;

(xiii) 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, such obligation to continue for 180 days or until the distribution described in such Registration Statement is completed, if earlier and following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include 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 not misleading or incomplete in light of the circumstances then existing;

(xiv) advise each Holder promptly after the Company shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the threatening of any proceeding for such purpose and promptly use all best efforts to prevent the issuance of any stop order should such be issued; and

(xv) deliver to each Holder of Registrable Securities an earnings statement of the Company (that will satisfy the provisions of Section 11(a) of the Act) covering a period of 12 months beginning after the effective date of the Registration Statement as soon as is reasonably practicable after the termination of such 12-month period.

 

-10-


(b) If the Company has delivered a Prospectus to the Selling Stockholders and after having done so the Prospectus is amended to comply with the requirements of the Securities Act, the Company shall promptly notify the Selling Stockholders and, if requested, the Selling Stockholders shall immediately cease making offers of Registrable Shares and return all Prospectuses to the Company. The Company shall promptly provide the Selling Stockholders with revised Prospectuses and, following receipt of the revised Prospectuses, the Selling Stockholders shall be free to resume making offers of the Registrable Shares.

(c) In the event that, in the judgment of the Company, it is advisable to suspend use of a Prospectus included in a Registration Statement due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify all Selling Stockholders to such effect, and, upon receipt of such notice, each such Selling Stockholder shall immediately discontinue any sales of Registrable Shares pursuant to such Registration Statement until such Selling Stockholder has received copies of a supplemented or amended Prospectus or until such Selling Stockholder is advised in writing by the Company that the then current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. Notwithstanding anything to the contrary herein, the Company shall not exercise its rights under this Section 2.3(c) to suspend sales of Registrable Shares for a period in excess of 30 days consecutively or 60 days in any 365-day period.

2.4 Allocation of Expenses. The Company will pay all Registration Expenses for all registrations under this Agreement; provided, however, that if a registration under Section 2.1 is withdrawn at the request of the Initiating Holders (other than as a result of information concerning the business or financial condition of the Company which is made known to the Selling Stockholders after the date on which such registration was requested) and if the Initiating Holders elect not to have such registration counted as a registration requested under Section 2.1, the Selling Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration.

2.5 Indemnification and Contribution.

(a) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless each Selling Stockholder, each underwriter of such Registrable Shares, and each other person, if any, who controls such Selling Stockholder or underwriter within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such Selling Stockholder, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities

Act, any preliminary prospectus or final prospectus contained in the Registration Statement, any free writing prospectus, or any amendment or supplement to such Registration Statement, (ii) the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation whether by action or inaction by the Company of the Securities Act, the Exchange Act, any state securities or Blue Sky law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities or Blue Sky law in connection with the Registration Statement or the qualification or compliance of the offering; and the Company will reimburse such Selling Stockholder, underwriter and each such controlling person for any legal or any other expenses reasonably incurred by such Selling Stockholder, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such Selling Stockholder, underwriter or controlling person specifically for use in the preparation thereof.

(b) In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each Selling Stockholder, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors and officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or (ii) any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, in the case of both (i) and (ii) if and to the extent (and only to the extent) that the statement or omission or alleged omission was made in reliance upon and in conformity with information relating to such Selling Stockholder furnished in writing to the Company by such Selling Stockholder specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; provided, however, that the obligations of a Selling Stockholder hereunder shall be limited to an amount equal to the net proceeds to such Selling Stockholder of Registrable Shares sold in connection with such registration.

(c) Each Indemnified Party shall give notice to the Indemnifying Party promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld, conditioned or delayed); and, provided,

 

-12-


further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.5 except to the extent that the Indemnifying Party is adversely affected by such failure. The Indemnified Party may participate in such defense at such party’s expense; provided, however, that the Indemnifying Party shall pay such expense if the Indemnified Party reasonably concludes that representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding; provided further that in no event shall the Indemnifying Party be required to pay the expenses of more than one law firm per jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also shall be responsible for the expenses of such defense if the Indemnifying Party does not elect to assume such defense. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed.

(d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in this Section 2.5 is due in accordance with its terms but for any reason is held to be unavailable to an Indemnified Party in respect to any losses, claims, damages and liabilities referred to herein, then the Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities to which such party may be subject in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Selling Stockholders on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company and the Selling Stockholders shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of material fact related to information supplied by the Company or the Selling Stockholders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Stockholders agree that it would not be just and equitable if contribution pursuant to this Section 2.5(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 2.5(d), (i) in no case shall any one Selling Stockholder be liable or responsible for any amount in excess of the net proceeds received by such Selling Stockholder from the offering of Registrable Shares and (ii) the Company shall be liable and responsible for any amount in excess of such proceeds; provided, however, that 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. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 2.5(d), notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom

 

-13-


contribution may be sought shall not relieve such party from any other obligation it or they may have thereunder or otherwise under this Section 2.5(d). No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

(e) The rights and obligations of the Company and the Selling Stockholders under this Section 2.5 shall survive the termination of this Agreement.

2.6 Other Matters with Respect to Underwritten Offerings. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering pursuant to Section 2.1, the Company agrees to (a) enter into an underwriting agreement containing customary representations and warranties with respect to the business and operations of the Company and customary covenants and agreements to be performed by the Company, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering; (b) use its best efforts to cause its legal counsel to render customary opinions to the underwriters and the Selling Stockholders with respect to the Registration Statement; and (c) use its best efforts to cause its independent public accounting firm to issue customary “cold comfort letters” to the underwriters and the Selling Stockholders with respect to the Registration Statement.

2.7 Information by Holder. Each holder of Registrable Shares included in any registration shall furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement.

2.8 “Lock-Up” Agreement; Confidentiality of Notices. Each Purchaser agrees, if requested by the Company and the managing underwriter of the Initial Public Offering, (i) not to (a) offer, pledge, announce the intention to sell, 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 Registrable Shares or other securities of the Company (excluding securities acquired in the Initial Public Offering or in the public market after such offering) or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of any Registrable Shares or other securities of the Company (excluding securities acquired in the Initial Public Offering or in the public market after such offering), whether any transaction described in clause (a) or (b) is to be settled by delivery of securities, in cash or otherwise, during the period beginning on the date of the filing of such Registration Statement with the Securities and Exchange Commission and ending 180 days after the date of the final prospectus relating to the Initial Public Offering (plus up to an additional 18 days to the extent requested by the managing underwriters for such offering in order to address NASD Rule 2711(f) of the Financial Industry Regulatory Authority, Inc. or any similar successor provision) and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing underwriters at the time of such offering; provided, that all stockholders of the Company then holding at least 1% of the outstanding Common Stock (on an as-converted basis) and all officers and directors of the Company enter into similar agreements. The obligations described in this Section 2.8 shall

 

-14-


not apply to a registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. In addition, in the event that the Company or the managing underwriter shall release a party from the obligations of this Section 2.8 (or any other similar agreement) then each other party bound by such section or similar agreement shall have a proportionate number of shares released from such restrictions.

The Company may impose stop-transfer instructions with respect to the Registrable Shares or other securities subject to the foregoing restriction until the end of such “lock-up” period.

Any Purchaser receiving any written notice from the Company regarding the Company’s plans to file a Registration Statement shall treat such notice confidentially and shall not disclose such information to any person other than as necessary to exercise its rights under this Agreement.

2.9 Limitations on Subsequent Registration Rights. The Company shall not, without the prior written consent of Purchasers holding at least 50.1% of the Registrable Shares then held by all Purchasers, enter into any agreement (other than this Agreement) with any holder or prospective holder of any securities of the Company which grants such holder or prospective holder rights to include securities of the Company in any Registration Statement, unless (a) such rights to include securities in a registration initiated by the Company or by Purchasers are not more favorable than the rights granted to Other Holders under Section 2.2, (b) no rights are granted to initiate a registration, other than registration pursuant to a registration statement on Form S-3 (or its successor) in which Purchasers are entitled to include Registrable Shares on a pro rata basis with such holders based on the number of shares of Common Stock (on an as-converted basis) owned by Purchasers and such holders and (c) such holder is bound by obligations substantively similar to the obligations of the Holders set forth in Sections 2.4, 2.5, 2.7 and 2.8.

2.10 Rule 144 Requirements. After the earliest of (i) the closing of the sale of securities of the Company pursuant to a Registration Statement, (ii) the registration by the Company of a class of securities under Section 12 of the Exchange Act, or (iii) the issuance by the Company of an offering circular pursuant to Regulation A under the Securities Act, the Company agrees to:

(a) make and keep current public information about the Company available, as those terms are understood and defined in Rule 144;

(b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and

 

-15-


(c) furnish to any holder of Registrable Shares upon request (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company, and (iii) such other reports and documents of the Company as such holder may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration.

2.11 Termination. All of the Company’s obligations to register Registrable Shares under Sections 2.1 and 2.2 shall terminate upon the earliest of (a) seven years after the closing of the Initial Public Offering, (b) the date on which no Purchaser holds any Registrable Shares or (c) a Public Company Sale.

3. Right of First Refusal.

3.1 Rights of Purchasers to Acquire Offered Securities.

(a) The Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange, any Offered Securities, unless in each such case the Company shall have first complied with this Section 3.1. The Company shall deliver to each Major Purchaser an Offer, which shall (i) identify and describe the Offered Securities, (ii) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (iii) identify the persons or entities (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged, and (iv) offer to issue and sell to or exchange with such Major Purchaser that is a Qualified Purchaser (A) such Qualified Purchaser’s Basic Amount and (B) such Qualified Purchaser’s Undersubscription Amount. Notwithstanding the other provisions of this Section 3.1, after delivery of the Offer, the Company may issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange, Offered Securities to the offerees or purchasers described in the Offer and upon the terms and conditions (including, without limitation, unit prices and interest rates) set forth in the Offer without complying with the time periods in subsection (b) of this Section 3.1, provided that the Company permits each Qualified Purchaser to purchase the maximum number of Offered Securities that such Qualified Purchaser would be entitled to purchase pursuant to this Section 3.1 on substantially the same terms as the Company sold the Offered Securities in the initial transaction, within 10 days after the Company receives a Notice of Acceptance from such Qualified Purchaser.

(b) To accept an Offer, in whole or in part, a Qualified Purchaser must deliver to the Company, on or prior to the date 15 days after the date of delivery of the Offer, a Notice of Acceptance providing a representation letter certifying that such Qualified Purchaser is an accredited investor within the meaning of Rule 501 under the Securities Act and indicating the portion of the Qualified Purchaser’s Basic Amount that such Qualified Purchaser elects to purchase and, if such Qualified Purchaser shall elect to purchase all of its Basic Amount, the Undersubscription Amount (if any) that such Qualified Purchaser elects to purchase. If the Basic Amounts subscribed for by all Qualified Purchasers are less than the total of all of the Basic Amounts available for purchase, then each Qualified Purchaser who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition

 

-16-


to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the Available Undersubscription Amount, each Qualified Purchaser who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Undersubscription Amount subscribed for by such Qualified Purchaser bears to the total Undersubscription Amounts subscribed for by all Purchasers, subject to rounding by the Board of Directors to the extent it deems reasonably necessary.

(c) The Company shall have 90 days from the expiration of the period set forth in Section 3.1(b) to issue, sell or exchange all or any part of the Refused Securities, but only to the offerees or purchasers described in the Offer (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) which are not more favorable, in the aggregate, to the acquiring person or persons or less favorable to the Company than those set forth in the Offer.

(d) In the event the Company shall propose to sell less than all the Refused Securities, then each Qualified Purchaser may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the Qualified Purchaser elected to purchase pursuant to Section 3.1(b) multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Qualified Purchasers pursuant to Section 3.1(b) prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Qualified Purchaser so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Qualified Purchasers in accordance with Section 3.1(a).

(e) Upon (i) the closing of the issuance, sale or exchange of all or less than all of the Refused Securities or (ii) such other date agreed to by the Company and Qualified Purchasers who have subscribed for a majority of the Offered Securities subscribed for by the Qualified Purchasers, such Qualified Purchaser or Purchasers shall acquire from the Company and the Company shall issue to such Qualified Purchaser or Purchasers, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 3.1(d) if any of the Qualified Purchasers has so elected, upon the terms and conditions specified in the Offer.

(f) The purchase by the Qualified Purchasers of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Qualified Purchasers of a purchase agreement and other ancillary agreements relating to such Offered Securities reasonably satisfactory in form and substance to the Qualified Purchasers and their respective counsel.

 

-17-


(g) Any Offered Securities not acquired by the Qualified Purchasers or other persons in accordance with Section 3.1(c) may not be issued, sold or exchanged until they are again offered to the Qualified Purchasers under the procedures specified in this Agreement.

(h) The rights of the Qualified Purchasers under this Section 3.1 shall not apply to:

(i) the issuance of any shares of Common Stock as a stock dividend to holders of Common Stock or upon any subdivision or combination of shares of Common Stock;

(ii) the issuance of securities as a dividend or distribution on shares of Preferred Stock (including the Shares);

(iii) the issuance of any shares of Common Stock upon conversion of shares of the Preferred Stock;

(iv) the issuance of shares of Common Stock or options with respect thereto (subject in either case to appropriate adjustment for stock splits, stock dividends, recapitalizations and similar events occurring after the date of this Agreement), issued or issuable to employees, directors or officers of, or consultants to, the Company or any Company Subsidiary pursuant to the 2008 Equity Incentive Plan or any other plan, agreement or arrangement approved by the Board of Directors of the Company;

(v) the issuance of securities pursuant to the bona fide acquisition of another corporation by the Company or any Company Subsidiary by merger, purchase of substantially all of the assets or other reorganization or to any joint venture agreement provided that such issuance is approved by the Board of Directors;

(vi) the issuance of shares of Common Stock by the Company in a Qualified Public Offering (as such term is defined in the Company’s Amended and Restated Certificate of Incorporation) or a public offering prior to or in connection with which all Preferred Stock is converted to Common Stock;

(vii) the issuance of shares of Common Stock, or the grant of options or warrants therefor, to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to non-convertible a debt financing, equipment leasing or real property leasing transaction provided such issuance is approved by the Board of Directors;

(viii) the issuance of securities issued in connection with sponsored research, collaboration, technology license, development, marketing or other similar agreements or strategic partnerships, provided, that such issuance is approved by the Board of Directors; or

(ix) the issuance of securities in connection with a transaction approved by holders of at least 50.1% of the outstanding shares of Preferred Stock voting together as a single class on an as-converted to Common Stock basis.

So long as any Shares are outstanding, the Company covenants and agrees that it will perform and observe the following covenants and provisions and will cause each Company Subsidiary to perform and observe such of the following covenants and provisions as are applicable to such Company Subsidiary:

(a) Payment of Taxes and Trade Debt. Pay and discharge all taxes, assessments and governmental charges or levies imposed upon it or upon its income or profits or business, or upon any properties belonging to it, prior to the date on which penalties attach thereto, and all lawful claims, which, if unpaid, might become a lien or charge upon any properties of the Company or a Company Subsidiary, other than those which are being contested in good faith if the Company shall have set aside on its books and shall have provided, in accordance with generally accepted accounting principles, adequate reserves with respect thereto; and pay in conformity with customary trade terms, all lease obligations, all trade debt, and all other indebtedness incident to its operations, except such as are being contested in good faith if the Company shall have set aside on its books and shall have provided, in accordance with generally accepted accounting principles, appropriate reserves with respect thereto.

(b) The Board of Directors shall meet on at least a quarterly basis, unless otherwise agreed by a majority of the Preferred Directors.

(c) The Company’s Amended and Restated Certificate of Incorporation shall at all times provide for the indemnification of the members of the Board of Directors to the fullest extent provided by the law of the jurisdiction in which the Company is organized.

4.12 Market Stand-Off Agreement with Future Security Holders; Right of First Refusal. Unless otherwise approved by the Purchasers who then are holders in interest of at least 50.1% of the then outstanding Shares, (i) the Company shall cause each future holder of its securities to enter into an agreement substantially similar to the market stand-off agreement set forth in Section 2.8 hereof and (ii) the Company will assign to the Major Purchasers any contractual right of first refusal it has to purchase shares of Common Stock from its stockholders that it elects not to exercise with such assignment being allocated to the Major Purchasers in accordance with the mechanism by which such shares would have been allocated pursuant to the Amended and Restated Right of First Refusal and Co-Sale Agreement dated of even date herewith by and among the Company, the Purchasers and the Key Holders party thereto. Notwithstanding clause (ii), the Major Purchasers acknowledge that the Company may not be able to assign its right to repurchase shares of Common Stock from stockholders who are subject to stock ownership policies of the Howard Hughes Medical Institute, whose ownership exceeds the 5% stock ownership policy of the Howard Hughes Medical Institute and whose agreements with the Company require transfers by such stockholders to the Company (either voluntarily or upon the Company’s exercise of a repurchase right) in order to ensure that such stockholders become compliant with such stock ownership policies.

4.13 Termination of Covenants. Other than the covenant contained in Section 4.11, all covenants of the Company contained in this Section 4 shall terminate upon the earlier of the closing of a Public Company Sale or the closing of an Initial Public Offering in which all Preferred Stock converts to Common Stock.

5. Confidentiality. Each Purchaser agrees that he, she or it will keep confidential and will not disclose, divulge or use for any purpose, other than to monitor its investment in the Company, any Confidential Information, unless such Confidential Information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 5 by such Purchaser), (b) is or has been independently developed or conceived by the Purchaser without use of the Company’s Confidential Information or (c) is or has been made known or disclosed to the Purchaser by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that a Purchaser may disclose Confidential Information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company, (ii) to any prospective purchaser of any Shares from such Purchaser as long as such prospective purchaser agrees to be bound by the provisions of this Section 5, (iii) to any Affiliated Party of such Purchaser provided that such party is obligated not to disclose, divulge or use any Confidential Information to the same extent as the Purchaser, or (iv) as may otherwise be required by law, provided that the Purchaser takes reasonable steps to minimize the extent of any such required disclosure. Notwithstanding the foregoing, such information shall not be deemed confidential for the purpose of enforcing this Agreement. To the extent that any Purchaser is party to an agreement with the Company that governs confidential information provided by the Company to such Investor and/or its Affiliated Parties under this Agreement and/or with respect to Board observer rights, the provisions of such agreement shall apply in lieu of the foregoing.

6. Transfers of Rights; Calculation of Share Numbers.

6.1 Transfer of Rights. This Agreement, and the rights and obligations of each Purchaser hereunder, may be assigned by such Purchaser to (a) any person or entity to which at least 500,000 Shares (subject to appropriate adjustment for stock splits, stock dividends, recapitalizations and similar events occurring after the date of this Agreement) are transferred by such Purchaser, or (b) to any Affiliated Party of such Purchaser, and, in each case, such transferee shall be deemed a “Purchaser” 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. Notwithstanding the foregoing, any person or entity to which any Shares or Registrable Shares are transferred by a Purchaser, whether voluntarily or by operation of law, shall be bound by the obligations under Section 2.8 to the same extent as if such transferee were a Purchaser hereunder and no Purchaser shall transfer any Shares or Registrable Shares unless the transferee provides a written instrument to the Company notifying the Company of such transfer and agreeing in writing to be bound by the terms of Section 2.8.

6.2 Calculation of Share Numbers. In determining the number of Shares owned by a Purchaser for purposes of exercising rights under this Agreement, (a) Shares owned by a Purchaser shall be deemed to include Shares which have been converted into Common Stock so long as such Common Stock is owned by such Purchaser and (b) all Shares held by Affiliated Parties shall be aggregated together (provided that no shares shall be attributed to more than one entity or person within any such group of Affiliated Parties).

7. General.

7.1 Severability. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement.

7.2 Specific Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this Agreement, each Purchaser shall be entitled to specific performance of the agreements and obligations of the Company hereunder and to such other injunctive or other equitable relief as may be granted by a court of competent jurisdiction.

7.3 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 the internal laws of the Commonwealth of Massachusetts (without reference to the conflicts of law provisions thereof), as to all other matters.

7.4 Notices. All notices, requests, consents and other communications under this Agreement shall be in writing and shall be deemed delivered (i) three business days after being sent by registered or certified mail, return receipt requested, postage prepaid or (ii) one business day after being sent via a reputable nationwide overnight courier service guaranteeing next business day delivery, in each case to the intended recipient as set forth below:

 

-26-


If to the Company, at 325 Vassar Street, Cambridge, MA 02139, Attention: Chief Executive Officer, or at such other address as may have been furnished in writing by the Company to the other parties hereto, with a copy to Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston, MA 02109, Attention: Rosemary G. Reilly, Esq.;

If to a Purchaser, at its address set forth on Exhibit A, or at such other address as may have been furnished in writing by such Purchaser to the other parties hereto.

Any party may give any notice, request, consent or other communication under this Agreement using any other means (including, without limitation, personal delivery, messenger service, telecopy, first class mail or electronic mail) addressed as set forth on Exhibit A hereto or such other address as may have been furnished in writing by a party to the other parties hereto, but no such notice, request, consent or other communication shall be deemed to have been duly given unless and until it is actually received by the party for whom it is intended. Any party may change the address to which notices, requests, consents or other communications hereunder are to be delivered by giving the other parties notice in the manner set forth in this Section 7.4.

7.5 Complete Agreement. This Agreement constitutes the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter.

7.6 Amendments and Waivers. This Agreement may be amended or terminated and the observance of any term of this Agreement may be waived with respect to all parties to this Agreement (either generally or in a particular instance and either retroactively or prospectively), with the written consent of the Company and Purchasers holding Shares representing at least 50.1% of the voting power of all Shares then held by Purchasers; provided that any amendment, termination or waiver to the terms of Section 2 (or a defined term used therein) that occurs after the closing of the Initial Public Offering shall instead require the written consent of the Company and Purchasers holding Registrable Shares representing at least 50.1% of the voting power of all Registrable Shares then held by all Purchasers. Notwithstanding the foregoing,

(a) this Agreement may not be amended or terminated and the observance of any term hereunder may not be waived with respect to any Purchaser without the written consent of such Purchaser unless such amendment, termination or waiver applies to all Purchasers in the same fashion (it being agreed that a waiver of the provisions of Section 3 with respect to a particular transaction shall be deemed to apply to all Qualified Purchasers in the same fashion if such waiver does so by its terms, notwithstanding the fact that certain Qualified Purchasers may nonetheless, by agreement with the Company, purchase securities in such transaction); and

(b) the definition of “Major Purchaser” shall not be amended in a manner that materially adversely impacts any Major Purchaser (and no such other action taken shall be taken hereunder that has the effect thereof) without the consent of such Major Purchaser

 

-27-


so long as at the time of such amendment such Major Purchaser holds at least 1% of the outstanding capital stock of the Company (taken on an as-converted to common stock basis), provided, that in the event such Major Purchaser subsequently falls below such 1% threshold, such Purchaser shall continue to be considered a Major Purchaser so long as it holds enough Shares to be deemed a Major Purchaser as determined at the time such shares were acquired, but in no event holds less than 75% of the Shares originally purchased by such Purchaser.

The Company shall give prompt written notice of any amendment or termination hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, termination or waiver. Any amendment, termination or waiver effected in accordance with this Section 7.6 shall be binding on all parties hereto, even if they do 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.

7.7 Amendment and Restatement of Prior Agreement. Upon execution of this Agreement by the Company and Purchasers (as defined in the Prior Investor Rights Agreement) holding Shares (as defined in the Prior Investor Rights Agreement) representing at least 62% of the voting power of all Shares (as defined in the Prior Investor Rights Agreement), the Prior Investor Rights Agreement shall be amended and restated to read in its entirety as set forth herein.

7.8 Pronouns. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa.

7.9 Counterparts; Facsimile Signatures. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of which together shall constitute one and the same document. This Agreement may be executed by facsimile signatures.

7.10 Section Headings and References. The section headings are for the convenience of the parties and in no way alter, modify, amend, limit or restrict the contractual obligations of the parties. Any reference in this agreement to a particular section or subsection shall refer to a section or subsection of this Agreement, unless specified otherwise.
