2. General; Securities Subject to this Agreement


 


(a) Grant of Rights


 


Insmed hereby grants registration rights to the Designated Shareholders with respect to the Registrable Securities held by such Designated Shareholders upon the terms and conditions set forth in this Agreement.


 


(b) Registrable Securities


 


For the purposes of this Agreement, Registrable Securities held by any Designated Shareholder will cease to be Registrable Securities, when (i) a Registration Statement covering such Registrable Securities has been declared effective under the Securities Act by the Commission and such Registrable Securities have been disposed of pursuant to such effective Registration Statement, (ii) in the opinion of counsel reasonably satisfactory to Insmed, the entire amount of the Registrable Securities held by any Designated Shareholder may be sold in a single sale, without any limitation as to volume or manner of sale pursuant to Rule 144 promulgated under the Securities Act or (iii) the Registrable Securities have ceased to be outstanding.


 


(c) Holders of Registrable Securities


 


A Person is deemed to be a holder of Registrable Securities whenever such Person owns of record Registrable Securities.  If Insmed receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, Insmed may act upon the basis of the instructions, notice or election received from the registered owner of such Registrable Securities.


 


(d) Transfer of Registration Rights


 


(i) Subject to the Shareholders’ Agreement, dated as of the date hereof, between Insmed and each of the Designated Holders, each Designated Shareholder may transfer or pledge Registrable Securities with the associated registration rights under this Agreement (including transfers occurring by operation of law or by reason of intestacy) to a Permitted Assignee or a pledgee (“Pledgee”) only if (1) such Permitted Assignee or Pledgee agrees in writing to be bound as a Designated Shareholder by the provisions of this Agreement, such agreement being substantially in the form of Annex A hereto, and (2) immediately following such transfer or pledge, the further disposition or transfer of such Registrable Securities by such Permitted Assignee or Pledgee would be restricted under the Securities Act and, in the opinion of counsel reasonably satisfactory to Insmed, the entire amount of all such Registrable Securities could not be sold in a single sale, without any limitation as to volume or manner of sale pursuant to Rule 144 promulgated under the Securities Act.  Upon any transfer or pledge of Registrable Securities other than as set forth in this Section 2(d), such securities shall no longer constitute Registrable Securities.


 


(ii) Subject to Section 2(b) hereof, if a Designated Shareholder assigns its rights under this Agreement in connection with the transfer of less than all of its Registrable Securities, the Designated Shareholder shall retain its rights under this Agreement with respect to its remaining Registrable Securities.  If a Designated Shareholder assigns its rights under this Agreement in connection with the transfer of all of its Registrable Securities, such Designated Shareholder shall have no further rights or obligations under this Agreement, except under Section 8 hereof in respect of offerings in which it participated.


 


3. Demand Registration


 


(a) Request for Demand Registration


 


.  To the extent permitted by applicable law and regulations, at any time that Insmed is not eligible to use Form S-3 under the Securities Act in connection with a secondary public offering of its equity securities after May 30, 2011, the Initiating Holders may make a written request to Insmed to register, and Insmed shall register, under the Securities Act (other than pursuant to a Registration Statement on Form S-4 or S-8), in accordance with the terms of this Agreement (a “Demand Registration”), the number of Registrable Securities stated in such request; provided, however, that Insmed shall not be obligated to effect (i) more than two (2) such Demand Registrations, (ii) a Demand Registration if the Initiating Holders propose to sell Registrable Securities in such Demand Registration at an anticipated aggregate offering price (calculated based upon the Market Price of the Registrable Securities on the date on which Insmed receives the written request for such Demand Registration) to the public of less than $10,000,000 unless such Demand Registration includes all of the then-outstanding Registrable Securities or (iii) any such Demand Registration within the Specified Period (or such shorter period as Insmed may determine in its sole discretion) after the effective date of any other Registration Statement of Insmed (other than a Registration Statement on Form S-4 or S-8).  For purposes of the preceding sentence, two or more Registration Statements related to the same offering by virtue of Rule 462(b) filed in response to one demand shall be counted as one Demand Registration.  In addition, if (1) the Board of Directors, in its good faith judgment, determines that any registration of Registrable Securities should not be made or continued because it would materially impede, delay or interfere with any material financing, offer and sale of securities, acquisition, merger, tender offer, business combination, corporate reorganization or other significant transaction involving Insmed or because such registration would require Insmed to disclose material nonpublic information that would not otherwise be required to be disclosed under applicable law and (2) Insmed has a bona fide business purpose for preserving the confidentiality of such transaction or information (a “Valid Business Reason”), (x) Insmed may postpone filing a Registration Statement (but not the preparation of the Registration Statement) relating to a Demand Registration until such Valid Business Reason no longer exists, but in no event for more than sixty (60) days after the date when the Demand Registration was requested or, if later, after the occurrence of the Valid Business Reason and (y) in case a Registration Statement has been filed relating to a Demand Registration, Insmed may postpone amending or supplementing such Registration Statement (in which case, if the Valid Business Reason no longer exists or if more than sixty (60) days have passed since such postponement, the Initiating Holders may request a new Demand Registration (which request shall not be counted as an additional Demand Registration for purposes of clause (i) above) or request the prompt amendment or supplement of such Registration Statement).  Insmed shall give written notice to all Designated Shareholders of its determination to postpone filing, amending or supplementing a Registration Statement and of the fact that the Valid Business Reason for such postponement no longer exists, in each case, promptly after the occurrence thereof.  Notwithstanding anything to the contrary contained herein, Insmed may not postpone a filing, amendment or supplement under this Section 3(a) due to a Valid Business Reason more than once in any twelve (12)-month period.  Each request for a Demand Registration by the Initiating Holders shall state the type and amount of the Registrable Securities proposed to be sold and the intended method of disposition thereof.


 


(b) Incidental or “Piggy-Back” Rights with Respect to a Demand Registration


 


Any Designated Shareholder that has not requested a registration under Section 3(a) hereof may, pursuant to this Section 3(b), offer its Registrable Securities under any Demand Registration.  Insmed shall (i) as promptly as practicable, but in no event later than five Business Days after the receipt of a request for a Demand Registration from the Initiating Holders, give written notice thereof to all of the Designated Shareholders (other than Initiating Holders which have requested a registration under Section 3(a) hereof), which notice shall specify the type and number of Registrable Securities subject to the request for Demand Registration, the names of the Initiating Holders and the intended method of disposition of such Registrable Securities, and (ii) subject to Section 3(e) hereof, include in the Registration Statement filed pursuant to the Demand Registration all of the Registrable Securities held by such Designated Shareholders from whom Insmed has received a written request for inclusion therein within five Business Days of the date on which such Designated Shareholders received the written notice referred to in clause (i) above.  Each such request by such Designated Shareholders shall specify the type and number of Registrable Securities proposed to be registered.  The failure of any Designated Shareholder to respond within such five Business Day period referred to in clause (ii) above shall be deemed to be a waiver of such Designated Shareholder’s rights under this Section 3(b) with respect to such Demand Registration.  Any Designated Shareholder may waive its rights under this Section 3(b) by giving written notice to Insmed.


 


(c) Effective Demand Registration


 


Subject to Section 3(a), Insmed shall use its reasonable best efforts (taking into account, among other things, accounting and regulatory matters) to file a Registration Statement relating to the Demand Registration and to use its reasonable best efforts to cause such Registration Statement to become effective as promptly as practicable but in no event later than one hundred twenty days after it receives a request under Section 3(a) hereof and to remain continuously effective for the lesser of (i) the period during which all Registrable Securities registered in the Demand Registration are sold or (ii) one hundred eighty (180) days; provided, however, that a registration shall not constitute a Demand Registration if (x) after such Demand Registration has become effective, such registration or the related offer, sale or distribution of Registrable Securities thereunder is interfered with by any stop order, injunction or other order or requirement of the Commission or other governmental agency or court for any reason not attributable to the Designated Shareholders and such interference is not thereafter eliminated or (y) the conditions specified in the underwriting agreement, if any, entered into in connection with such Demand Registration are not satisfied or waived as a result of an action or inaction by Insmed.


 


(d) Expenses


 


Except as provided in Section 3(g) or the last sentence of Section 7(d) hereof, Insmed shall pay all Registration Expenses in connection with a Demand Registration, whether or not such Demand Registration becomes effective.


 


(e) Underwriting Procedures


 


If the Majority Initiating Holders so elect, Insmed shall use its reasonable best efforts to cause the offering made pursuant to such Demand Registration pursuant to this Section 3 to be in the form of a firm commitment underwritten public offering and the managing underwriter or underwriters selected for such offering shall be the Approved Underwriter selected in accordance with Section 3(f) hereof.  In connection with any Demand Registration under this Section 3 involving an underwritten public offering, none of the Registrable Securities held by any Designated Shareholder making a request for inclusion of such Registrable Securities pursuant to Section 3(a) or 3(b) hereof shall be included in such underwritten public offering unless such Designated Shareholder accepts the terms of the offering as agreed upon by Insmed, the Majority Initiating Holders and the Approved Underwriter (including, without limitation, offering price, underwriting commissions or discounts and lockup agreement terms), and then only in such quantity as set forth below.  If the Approved Underwriter advises Insmed that the aggregate amount of such Registrable Securities requested to be included in such offering is sufficiently large to have a material adverse effect on the distribution or sales price of the Registrable Securities in such offering, then Insmed shall include in such Demand Registration, to the extent of the amount that the Approved Underwriter believes may be sold without causing such material adverse effect, first, such number of Registrable Securities of the Designated Shareholders that are participating in such offering pursuant to Section 3(a) or 3(b) hereof, which Registrable Securities shall be allocated pro rata among such Designated Shareholders participating in the offering, based on the number of Registrable Securities held by each such Designated Shareholder, second, any other securities of Insmed requested by any other holders thereof to be included in such registration, pro rata among such other holders based on the number of securities held by each such holder, and third, securities offered by Insmed for its own account.


 


(f) Selection of Underwriters


 


If any Demand Registration or S-3 Registration, as the case may be, of Registrable Securities is in the form of an underwritten public offering, Insmed shall select and obtain one or more investment banking firms of national reputation to act as the managing underwriter or underwriters of the offering; provided, however, that such firm or firms shall, in any case, also be approved by the Majority Initiating Holders or Majority Shelf Take-Down Shareholders, as the case may be, such approval not to be unreasonably delayed or withheld.  An investment banking firm or firms selected pursuant to this Section 3(f) shall be referred to as the “Approved Underwriter” herein.


 


(g) Withdrawal


 


The Majority Initiating Holders shall be entitled to withdraw or revoke a request for a Demand Registration without the prior written consent of Insmed if (i) such withdrawal or revocation is as a result of facts or circumstances arising after the date on which a request for a Demand Registration was made and the Majority Initiating Holders reasonably determine that participation in such registration would have a material adverse effect on the Initiating Holders or (ii) the Initiating Holders agree to pay all fees and expenses incurred by Insmed in connection with such withdrawn registration (each, a “Permitted Withdrawal”).  If a Permitted Withdrawal occurs under clause (i) above, the related Demand Registration shall be counted as a Demand Registration for purposes of Section 3(a) hereof, and if a Permitted Withdrawal occurs under clause (ii) above, the related Demand Registration shall not be counted as a Demand Registration for purposes of Section 3(a) hereof.  Any Permitted Withdrawal shall constitute and effect an automatic withdrawal by all other Initiating Holders and any other Designated Shareholder participating in such Demand Registration pursuant to the provisions of Section 3(b) hereof.


 


4. Incidental or “Piggy-Back” Registration


 


(a) Request for Incidental or “Piggy-Back” Registration


 


After May 30, 2011, if Insmed proposes to file a Registration Statement with respect to an offering of Common Stock by Insmed for its own account (other than a Registration Statement on Form S-4 or S-8) or for the account of any stockholder of Insmed other than Designated Shareholders pursuant to Sections 3 and 5 hereof, then Insmed shall give written notice (an “Incidental Registration Notice”) of such proposed filing to each of the Designated Shareholders at least thirty (30) days before the anticipated filing date, which notice shall describe the proposed registration and distribution, the proposed date of filing of such Registration Statement, any proposed managing underwriter or underwriters and a good faith estimate by Insmed of the proposed maximum offering price thereof, as such price is proposed to appear on the facing page of such Registration Statement, and offer such Designated Shareholders the opportunity to register the number of Registrable Securities that each such Designated Shareholder may request (an “Incidental Registration”).  Any such request by a Designated Shareholder must be made in writing and received by Insmed within five Business Days of the date on which the Designated Shareholder received the Incidental Registration Notice.  The failure of any Designated Shareholder to respond to an Incidental Registration Notice within ten (10) Business Days shall be deemed a waiver of such Designated Shareholder’s rights under this Section 4(a) with respect to such Incidental Registration.  Insmed shall use its reasonable best efforts to cause the managing underwriter or underwriters in the case of a proposed underwritten public offering (the “Insmed Underwriter”) to permit each Designated Shareholder who has requested in writing to participate in the Incidental Registration pursuant to this Section 4(a) to include the number of such Designated Shareholder’s Registrable Securities indicated by such Designated Shareholder in such offering on the same terms and conditions as the Common Stock of Insmed or the account of such other stockholder, as the case may be, included therein.  Any withdrawal of the Registration Statement by Insmed for any reason shall constitute and effect an automatic withdrawal of any Incidental Registration related thereto.  In connection with any Incidental Registration under this Section 4(a) involving an underwritten public offering, Insmed shall not be required to include any Registrable Securities in such underwritten public offering unless the Designated Shareholders thereof accept the terms of the underwritten public offering as agreed upon between Insmed, such other stockholders, if any, and Insmed Underwriter (including, without limitation, offering price, underwriting commissions or discounts and lock-up agreement terms), and then only in such quantity as set forth below.  If the Insmed Underwriter determines that the aggregate amount of the securities requested to be included in such offering is sufficiently large to have a material adverse effect on the distribution or sales price of the securities in such offering, then Insmed shall include in such Incidental Registration, to the extent of the amount that the Insmed Underwriter believes may be sold without causing such material adverse effect, first, (i) all of the securities to be offered for the account of Insmed, in the case of an Insmed initiated Incidental Registration or (ii) all of the securities to be offered for the account of the stockholders who have requested such Incidental Registration, in the case of a stockholder initiated Incidental Registration, second, any Registrable Securities and any other shares of Common Stock requested by holders thereof (including the Designated Shareholders) to be included in such registration (to the extent that the holders of such securities do not have priority to be included in such registration), pro rata among the Designated Shareholders and such other holders based on the number of securities held by each such holder, and third, all of the securities to be offered for the account of Insmed, in the case of an Incidental Registration initiated by any stockholder of Insmed.


 


(b) Expenses


 


Except as provided in the last sentence of Section 7(d) hereof, Insmed shall bear all Registration Expenses in connection with any Incidental Registration pursuant to this Section 4, whether or not such Incidental Registration becomes effective.


 


5. Form S-3 Registration


 


(a) Form S-3 Registration


 


If Insmed is eligible to use Form S-3 under the Securities Act in connection with a secondary public offering of its equity securities, Insmed shall register under the Securities Act on Form S-3 (an “S-3 Registration”) the sale of all of the Registrable Securities (which S-3 Registration shall be a shelf registration pursuant to Rule 415 promulgated under the Securities Act) provided herein.  Subject to the terms of this Agreement, Insmed shall use its reasonable best efforts to file a Registration Statement relating to the S-3 Registration (taking into account, among other things, accounting and regulatory matters) and to use its reasonable best efforts to cause such Registration Statement to become effective, in each case, as promptly as practicable but in no event later than the Target Filing Date.  Subject to the terms of this Agreement, if the Registration Statement for an S-3 Registration ceases to be effective after the third anniversary of its effectiveness, if Insmed is eligible to use Form S-3 under the Securities Act in connection with a secondary public offering of its equity securities, at the written request of the Majority Designated Shareholders, Insmed shall use its reasonable best efforts to file a new Registration Statement relating to the S-3 Registration (taking into account, among other things, accounting and regulatory matters) and to use its reasonable best efforts to cause such Registration Statement to become effective, in each case, as promptly as practicable but in no event later than ninety (90) days after the prior Registration Statement ceases to be effective; provided, that the Designated Shareholders request for inclusion in the new Registration Statement relating to such S-3 Registration at least $10,000,000 of Registrable Securities (calculated based upon the Market Price of the Registrable Securities on the date which the Majority Designated Shareholders make such request).  If the Majority S-3 Participating Shareholders request, and if Insmed is a Well-Known Seasoned Issuer, Insmed shall cause such S-3 Registration to be made pursuant to an Automatic Shelf Registration Statement and may omit the names of the S-3 Participating Shareholders and the amount of the Registrable Securities to be offered thereunder.  Any Registration Statement filed under this Section 5(a) shall be referred to as a “Form S-3 Shelf Registration Statement.”


 


(b) Form S-3 Underwriting Procedures


 


In an Underwritten Shelf Take-Down, the managing underwriter or underwriters selected for such offering shall be the Approved Underwriter selected in accordance with Section 3(f) hereof.  In connection with an Underwritten Shelf Take-Down, none of the Registrable Securities held by any Designated Shareholder having such Registrable Securities included pursuant to Section 5(a) hereof shall be included in such Underwritten Shelf Take-Down unless such Designated Shareholder accepts the terms of the offering as agreed upon by Insmed, the Majority Shelf Take-Down Shareholders and the Approved Underwriter (including, without limitation, offering price, underwriting commissions and discounts and lock-up agreement terms) and then only in such quantity as set forth below.  If the Approved Underwriter advises Insmed that the aggregate amount of such Registrable Securities requested to be included in such offering is sufficiently large to have a material adverse effect on the distribution or sales price of the Registrable Securities in such offering then Insmed shall include in such offering, to the extent of the amount that the Approved Underwriter believes may be sold without causing such material adverse effect, first, such number of Registrable Securities of the Designated Shareholders that are participating in such Underwritten Shelf Take-Down, which Registrable Securities shall be allocated pro rata among such Designated Shareholders participating in such Undewritten Shelf Take-Down, based on the number of Registrable Securities held by each such Designated Shareholder, second, any other securities of Insmed requested by any other holders thereof to be included in such Underwritten Shelf Take-Down and third, securities offered by Insmed for its own account.  Notwithstanding the foregoing, immediately upon determination of the price at which such Registrable Securities are to be sold in an offering in an S-3 Registration that is an Underwritten Shelf Take-Down, if such price is below the price which the Majority Shelf Take-Down Shareholders find acceptable, then such Majority Shelf Take-Down Shareholders shall then have the right, by written notice to Insmed, to withdraw their Registrable Securities from being included in such offering; provided, that such a withdrawal by such Majority Shelf Take-Down Shareholders shall constitute and effect an automatic withdrawal by all other S-3 Participating Shareholders.


 


(c) Limitations on Form S-3 Registrations


 


If the Board of Directors determines that a Valid Business Reason exists, (x) Insmed may postpone filing a Registration Statement relating to an S-3 Registration (but not the preparation of the Registration Statement) until such Valid Business Reason no longer exists, but in no event for more than sixty (60) days after the Target Filing Date or, if later, after the occurrence of the Valid Business Reason and (y) in case a Registration Statement has been filed relating to an S-3 Registration, Insmed may postpone amending or supplementing such Registration Statement (in which case, if the Valid Business Reason no longer exists or if more than sixty (60) days have passed since such postponement, the Majority S-3 Participating Shareholders may request the prompt amendment or supplement of such Registration Statement or a new S-3 Registration).  Insmed shall give written notice to all Designated Shareholders of its determination to postpone or delay amending or supplementing a Registration Statement and of the fact that the Valid Business Reason for such postponement or delay no longer exists, in each case, promptly after the occurrence thereof.  Notwithstanding anything to the contrary contained herein, Insmed may not postpone a filing or delay amending or supplementing a filing under this Section 5(c) due to a Valid Business Reason more than once in any six-month period.


 


(d) Expenses


 


Except as provided in the last sentence of Section 7(d) hereof, Insmed shall bear all Registration Expenses in connection with any S-3 Registration pursuant to this Section 5, whether or not such S-3 Registration becomes effective.


 


(e) Automatic Shelf Registration Statement


 


After the Registration Statement with respect to an S-3 Registration that is an Automatic Shelf Registration Statement becomes effective, upon written request by the S-3 Participating Shareholders, Insmed shall, as promptly as practicable after receiving such request, (i) file with the Commission a prospectus supplement naming the S-3 Participating Shareholders as selling stockholders and the amount of Registrable Securities to be offered and include, to the extent not included or incorporated by reference in the Registration Statement, any other information omitted from the Prospectus used in connection with such Registration Statement as permitted by Rule 430B promulgated under the Securities Act (including the plan of distribution and the names of any underwriters, placement agents or brokers) and (ii) pay any necessary filing fees to the Commission within the time period required.


 


(f) Shelf Take-Downs


 


(i)   Any Designated Shareholder (an “Initiating Shelf Holder”) that holds Registrable Securities included in a Form S-3 Shelf Registration Statement may initiate an offering or sale of all or part of such Registrable Securities (a “Shelf Take-Down”), in which case the provisions of this Section 5(f) shall apply.


 


(ii) If in connection with any Shelf Take-Down, the Majority Shelf Take-Down Shareholders so elect in a written request delivered to Insmed (an “Underwritten Shelf Take-Down Notice”), a Shelf Take-Down may be in the form of an underwritten public offering (an “Underwritten Shelf Take-Down”) and, subject to the limitations set forth in the proviso to Section 5(b), Insmed shall file and effect an amendment or supplement to its Form S-3 Shelf Registration Statement for such purpose as soon as practicable.   Such Majority Shelf Take-Down Shareholders shall indicate in such Underwritten Shelf Take-Down Notice whether it intends for such Underwritten Shelf Take-Down to involve a customary “road show” (including an “electronic road show”) or other substantial marketing effort by the underwriters (a “Marketed Underwritten Shelf Take-Down”).  Upon receipt of an Underwritten Shelf Take-Down Notice indicating that such Underwritten Shelf Take-Down will be a Marketed Underwritten Shelf Take-Down, Insmed shall promptly (but in any event no later than ten Business Days prior to the expected date of such Marketed Underwritten Shelf Take-Down) give written notice of such Marketed Underwritten Shelf Take-Down to all other S-3 Participating Shareholders and shall permit the participation of all such S-3 Participating Shareholders that request inclusion in such Marketed Underwritten Shelf Take-Down who respond in writing within five Business Days after the receipt of such notice of their election to participate.  The provisions of Section 5(b) shall apply with respect to the right of the Initiating Shelf Holder and any other Shelf Holder to participate in any Underwritten Shelf Take-Down.


 


(iii) If any Initiating Shelf Holder desires to effect a Shelf Take-Down that does not constitute a Marketed Underwritten Shelf Take-Down (a “Non-Marketed Underwritten Shelf Take-Down”), such Initiating Shelf Holder shall so indicate in a written request delivered to Insmed no later than two Business Days prior to the expected date of such Non-Marketed Underwritten Shelf Take-Down, which request shall include (i) the total number of Registrable Securities expected to be offered and sold in such Non-Marketed Underwritten Shelf Take-Down, (ii) the expected plan of distribution of such Non-Marketed Underwritten Shelf Take-Down and (iii) the action or actions required (including the timing thereof) in connection with such Non-Marketed Underwritten Shelf Take-Down (including the delivery of one or more stock certificates representing shares of Registrable Securities to be sold in such Non-Marketed Underwritten Shelf Take-Down), and, subject to the limitations set forth in Sections 5(a) and (b), Insmed shall file and effect an amendment or supplement to its Form S-3 Shelf Registration Statement for such purpose as soon as practicable.


 


6. Holdback Agreements


 


(a) Restrictions on Public Sale by Designated Shareholders


 


(i) To the extent requested by the Approved Underwriter or the Insmed Underwriter, as the case may be, in the case of an underwritten public offering, each Designated Shareholder (other than any Pledgee) agrees (x) not to effect any public sale or distribution of any Registrable Securities or of any securities convertible into or exchangeable or exercisable for such Registrable Securities, including a sale pursuant to Rule 144 (or any successor rule or regulation) promulgated under the Securities Act, or offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or enter into any hedging or similar transaction with the same economic effect as a sale of, any Registrable Securities and (y) except as otherwise consented to by Insmed, not to make any request for a Demand Registration or S-3 Registration under this Agreement, in each case, during the Specified Period following the effective date of such Registration Statement, except in each case as part of such underwritten public offering.


 


(ii) Notwithstanding anything herein to the contrary, no Pledgee shall be required to agree to any restriction on its ability to trade in any securities, including the restrictions set forth in this Section 6(a).  The Designated Shareholders hereby agree that they shall act in good faith with respect to the restrictions set forth in this Section 6(a) and shall take no action or omit to take any action with the intention of circumventing or evading the restrictions applicable to them under this Section 6(a).


 


(b) Restrictions on Public Sale by Insmed


 


Unless Insmed shall have received the prior written consent of the Majority Designated Shareholders, Insmed agrees not to (i) effect any public sale or distribution of any of its securities, or any securities convertible into or exchangeable or exercisable for such securities (except pursuant to registrations on Form S-4 or S-8), (ii) file any Registration Statements relating to the registration of securities for Insmed’s account (except pursuant to registrations on Form S-4 or S-8) or (iii) make any public announcements related to clause (i) or (ii), in each case, during the period beginning on the effective date of any Registration Statement relating to an underwritten public offering in which the Designated Shareholders of Registrable Securities are participating pursuant to Section 3 or 5 hereof and ending on the earlier of (x) the date on which all Registrable Securities registered on such Registration Statement are sold and (y) the Specified Period after the effective date of such Registration Statement (except as part of such registration).


 


7. Registration Procedures


 


(a) Obligations of Insmed


 


Whenever registration of Registrable Securities has been requested or required pursuant to Section 3, Section 4 or Section 5 hereof, Insmed shall use its reasonable best efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method of distribution thereof as quickly as practicable, and in connection with any such request, Insmed shall:


 


(i) use its reasonable best efforts (taking into account, among other things, accounting and regulatory matters) to prepare and file with the Commission a Registration Statement on any form for which Insmed then qualifies or which counsel for Insmed shall deem appropriate and which form shall be available for the sale of such Registrable Securities in accordance with the intended method of distribution thereof, and use its reasonable best efforts to cause such Registration Statement to become effective; provided, however, that (x) before filing a Registration Statement or Prospectus or any amendments or supplements thereto (including, without limitation, any documents incorporated by reference therein), or before using any Free Writing Prospectus, Insmed shall provide one firm of legal counsel selected by the Designated Shareholders holding a majority of the Registrable Securities being registered in such registration (“Designated Shareholders’ Counsel”), any managing underwriter or broker/dealer participating in any disposition of such Registrable Securities pursuant to a Registration Statement and any attorney retained by any such managing underwriter or broker/dealer (each, an “Inspector” and collectively, the “Inspectors”) with an adequate and appropriate opportunity to review and comment on such Registration Statement and each Prospectus included therein (and each amendment or supplement thereto) and each Free Writing Prospectus to be filed with the Commission, subject to such documents being under Insmed’s control, and (y) Insmed shall promptly notify the Designated Shareholders’ Counsel and each seller of Registrable Securities pursuant to such Registration Statement of any stop order issued or threatened by the Commission and take all reasonable best efforts required to prevent the entry of such stop order or to remove it if entered;


 


(ii) prepare and file with the Commission such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for the lesser of (x) one hundred eighty (180) days (or, in the case of an S-3 Registration, three years from the effective date of the Registration Statement if such Registration Statement is filed pursuant to Rule 415 promulgated under the Securities Act) and (y) such shorter period which will terminate when all Registrable Securities covered by such Registration Statement have been sold (or, if such Registration Statement is an Automatic Shelf Registration Statement, on the third anniversary of the date of filing of such Automatic Shelf Registration Statement); and shall comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement.  Notwithstanding the foregoing, Insmed shall be entitled at all reasonable times to suspend a Registration Statement that includes Registrable Securities during the pendency of any amendments required by this Section 7(a)(ii).  Such suspension or suspensions shall be effective upon transmittal of notice to an affected Designated Shareholder, in compliance with, and using the most expeditious practical means of communication permitted by Section 10(e) below.


 


(iii) furnish to each seller of Registrable Securities, prior to filing a Registration Statement relating to Registrable Securities, at least one copy of such Registration Statement as is proposed to be filed, and thereafter such number of copies of such Registration Statement, each amendment and supplement thereto (in each case including all exhibits thereto), the Prospectus included in such Registration Statement (including each preliminary Prospectus), any Prospectus filed under Rule 424 under the Securities Act and any Free Writing Prospectus as each such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;


 


(iv) register or qualify such Registrable Securities under such other securities or “blue sky” laws of such jurisdictions as any seller of Registrable Securities may reasonably request, and continue such registration or qualification in effect in such jurisdiction for as long as permissible pursuant to the laws of such jurisdiction, or for as long as any such seller requests or until all of such Registrable Securities are sold, whichever is shortest, and do any and all other acts and things which may be reasonably necessary or advisable to enable any such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller; provided, however, that Insmed shall not be required to (x) qualify generally to do business as a foreign entity in any jurisdiction where it is not then so qualified, (y) subject itself to taxation in any such jurisdiction or (z) consent to general service of process in any such jurisdiction;


 


(v) promptly notify each seller of Registrable Securities: (A) when a Prospectus, any Prospectus supplement, any Free Writing Prospectus, a Registration Statement or a post-effective amendment to a Registration Statement has been filed with the Commission, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (B) of any request by the Commission or any other federal or state governmental authority for amendments or supplements to a Registration Statement, related Prospectus or Free Writing Prospectus or for additional information; (C) of the issuance by the Commission or any other governmental authority of any stop order suspending the effectiveness of a Registration Statement relating to Registrable Securities or of any order suspending or preventing the use of any related prospectus or the initiation or threatening of any proceedings for that purpose; (D) of the receipt by Insmed of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceedings for such purpose; (E) of the existence of any fact or happening of any event (including the passage of time) of which Insmed has knowledge which makes any statement of a material fact in such Registration Statement, related Prospectus or Free Writing Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue or which would require the making of any changes in the Registration Statement, Prospectus or Free Writing Prospectus in order that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of such Prospectus or Free Writing Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and (F) determination by counsel of Insmed that a post-effective amendment to a Registration Statement relating to Registrable Securities is advisable;


 


(vi) use its reasonable best efforts to, upon the occurrence of any event contemplated by Section 7(a)(v)(E) hereof or, subject to Sections 3(a) and 5(c) hereof, the existence of a Valid Business Reason, prepare a supplement or amendment to such Registration Statement, related Prospectus or Free Writing Prospectus and furnish to each seller of Registrable Securities a reasonable number of copies of such supplement to, or amendment of, such Registration Statement, Prospectus or Free Writing Prospectus as may be necessary so that, after delivery to the purchasers of such Registrable Securities, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of such Prospectus or Free Writing Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;


 


(vii) enter into and perform customary agreements (including an underwriting agreement in customary form with the Approved Underwriter or Insmed Underwriter, if any, selected as provided in Section 3, Section 4 or Section 5 hereof, as the case may be) and take such other reasonable best actions as are reasonably required in order to facilitate the disposition of such Registrable Securities, including causing its officers to participate in “road shows” and other information meetings organized by the Approved Underwriter or Insmed Underwriter;


 


(viii) make available at reasonable times for inspection by any Inspector all pertinent financial and other records, pertinent corporate documents and properties of Insmed and its subsidiaries (collectively, the “Records”) as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause Insmed’s and its subsidiaries’ officers, directors and employees, and the independent public accountants of Insmed, to supply all information reasonably requested by any such Inspector in connection with such Registration Statement.  Records that Insmed determines, in good faith, to be confidential and which it notifies the Inspectors are confidential shall not be disclosed by the Inspectors (and the Inspectors shall confirm their agreement in writing in advance to Insmed if Insmed shall so request) unless (x) the disclosure of such Records is necessary, in Insmed’s judgment, to avoid or correct a misstatement or omission in the Registration Statement, (y) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction after exhaustion of all appeals therefrom or (z) the information in such Records was known to the Inspectors on a non-confidential basis prior to its disclosure by Insmed or has been made generally available to the public.  Each seller of Registrable Securities agrees that it shall, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, promptly give notice to Insmed and allow Insmed, at Insmed’s expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential.  In the event that Insmed is unsuccessful in preventing the disclosure of such Records, such seller agrees that it shall furnish only such portion of those Records that it is advised by counsel is legally required and shall exercise all reasonable efforts to obtain reliable assurance that confidential treatment will be accorded to those Records;


 


(ix) if such sale is pursuant to an underwritten offering, obtain a “cold comfort” letter dated the effective date of the Registration Statement and the date of the closing under the underwriting agreement from Insmed’s independent public accountants in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing underwriter reasonably requests;


 


(x) if such sale is pursuant to an underwritten offering, furnish, at the request of any seller of Registrable Securities on the date such securities are delivered to the underwriters for sale pursuant to such registration, an opinion, dated such date, of counsel representing Insmed for the purposes of such registration, addressed to the underwriters, covering such legal matters with respect to the registration in respect of which such opinion is being given as the underwriters may reasonably request and are customarily included in such opinions;


 


(xi) comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable but no later than fifteen months after the effective date of the Registration Statement, an earnings statement covering a period of twelve months beginning after the effective date of the Registration Statement, in a manner which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated under the Securities Act;


 


(xii) cause as of the effective date of the Registration Statement, any shares of Common Stock included in the Registration Statement to be listed on each securities exchange on which the Common Stock is then listed, including but not limited to the Nasdaq Capital Market, provided that the applicable listing requirements are satisfied;


 


(xiii) keep Designated Shareholders’ Counsel reasonably advised in writing as to the initiation and progress of any registration hereunder; provided, that Insmed shall provide Designated Shareholders’ Counsel with all correspondence with the Commission in connection with any Registration Statement filed hereunder to the extent that such Registration Statement has not been declared effective on or prior to the date required hereunder;


 


(xiv) cooperate with each seller of Registrable Securities and each underwriter participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA;


 


(xv) cause the Registrable Securities covered by such Registration Statement to be registered with or approved by such other governmental agencies or authorities, as may be reasonably necessary by virtue of the business and operations of Insmed to enable the seller or sellers of Registrable Securities to consummate the disposition of such Registrable Securities;


 


(xvi) within the deadlines specified by the Securities Act and the rules promulgated thereunder, make all required filings of all Prospectuses and Free Writing Prospectuses with the Commission;


 


(xvii) within the deadlines specified by the Securities Act and the rules promulgated thereunder, make all required filing fee payments in respect of any Registration Statement or Prospectus used under this Agreement (and any offering covered thereby); and


 


(xviii) take all other steps reasonably necessary and advisable to effect the registration of the Registrable Securities contemplated hereby and reasonably cooperate with the holders of such Registrable Securities to facilitate the disposition of such Registrable Securities pursuant thereto.


 


(b) Seller Requirements


 


In connection with any offering under any Registration Statement under this Agreement, each Designated Shareholder (i) shall promptly furnish to Insmed in writing such information with respect to such Designated Shareholder and the intended method of disposition of its Registrable Securities as Insmed may reasonably request or as may be required by law or regulations for use in connection with any related Registration Statement or Prospectus (or amendment or supplement thereto) and all information required to be disclosed in order to make the information previously furnished to Insmed by such Designated Shareholder not contain a material misstatement of fact or necessary to cause such Registration Statement or Prospectus (or amendment or supplement thereto) not to omit a material fact with respect to such Designated Shareholder necessary in order to make the statements therein not misleading; (ii) shall comply with the Securities Act and the Exchange Act and all applicable state securities laws and comply with all applicable regulations in connection with the registration and the disposition of the Registrable Securities; and (iii) shall not use any Free Writing Prospectus without the prior written consent of Insmed.  If any seller of Registrable Securities fails to provide such information required to be included in such Registration Statement by applicable securities laws or otherwise necessary or desirable in connection with the disposition of such Registrable Securities in a timely manner after written request therefor, Insmed may exclude such seller’s Registrable Securities from a registration under Sections 3, 4 or 5 hereof.


 


(c) Notice to Discontinue


 


Each Designated Shareholder agrees that, upon receipt of any notice from Insmed of the happening of any event of the kind described in Section 7(a)(v)(E) hereof or, subject to Section 3(a) and 5(c) hereof, the existence of Valid Business Reason, such Designated Shareholder shall forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Designated Shareholder’s receipt of the copies of the supplemented or amended Prospectus or Free Writing Prospectus contemplated by Section 7(a)(vi) hereof (or if no supplemental or amended prospectus or Free Writing Prospectus is required, upon confirmation from Insmed that use of the Prospectus or Free Writing Prospectus is once again permitted) and, if so directed by Insmed, such Designated Shareholder shall deliver to Insmed (at Insmed’s expense) all copies, other than permanent file copies then in such Designated Shareholder’s possession, of the Prospectus or Free Writing Prospectus covering such Registrable Securities which is current at the time of receipt of such notice.  If Insmed shall give any such notice, Insmed shall extend the period during which such Registration Statement shall be maintained effective pursuant to this Agreement  by the number of days during the period from and including the date of the giving of such notice and including the date when sellers of such Registrable Securities under such Registration Statement shall have received the copies of the supplemented or amended Prospectus or Free Writing Prospectus contemplated by and meeting the requirements of Section 7(a)(v) hereof (or if no supplemental or amended prospectus or Free Writing Prospectus is required, upon confirmation from Insmed that use of the Prospectus or Free Writing Prospectus is once again permitted); provided, that, no single suspension under this Section 7(c) shall exceed forty-five (45) days in any one hundred and eight (180) day period and in no event shall more than one suspension event exceed, in the aggregate, sixty (60) days in any twelve (12) month period.

Except as otherwise provided herein, including but not limited to the last sentence of this Section 7(d), Insmed shall pay all expenses arising from or incident to its performance of, or compliance with, this Agreement, including, without limitation (i) all expenses, including filing fees, in connection with the preparation and filing of the Registration Statement, preliminary prospectus or final prospectus and amendments and supplements thereto, (ii) Commission, stock exchange and FINRA registration (including any counsel retained in connection with FINRA registration) and filing fees, (iii) transfer agents’ and registrars’ fees and expenses, (iv) all fees and expenses incurred in complying with state securities or “blue sky” laws (including reasonable fees, charges and disbursements of counsel to any underwriter incurred in connection with “blue sky” qualifications of the Registrable Securities as may be set forth in any underwriting agreement), (v) all printing, messenger and delivery expenses, (vi) the fees, charges and expenses of counsel to Insmed and of its independent registered public accounting firm and any other accounting fees, charges and expenses incurred by Insmed (including, without limitation, any expenses arising from any “cold comfort” letters or any special audits incident to or required by any registration or qualification), (vii) the reasonable fees, charges and expenses of the Designated Shareholders’ Counsel (including without limitation the reasonable fees, charges and expenses incurred in connection with any amendments to a Registration Statement) and (viii) any liability insurance or other premiums for insurance obtained in connection with any Demand Registration or piggy-back registration thereon, Incidental Registration or S-3 Registration pursuant to the terms of this Agreement, regardless of whether such Registration Statement is declared effective.  All of the expenses described in the preceding sentence of this Section 7(d) are referred to herein as “Registration Expenses.”  The Designated Shareholders of Registrable Securities sold pursuant to a Registration Statement shall bear the expense of any broker’s commission or underwriter’s discount or commission relating to the registration and sale of such Designated Shareholders’ Registrable Securities and shall bear the fees and expenses of their own counsel (other than the Designated Shareholders’ Counsel).

In connection with any offering in which a Designated Shareholder is participating pursuant to Section 3, 4 or 5 hereof, such Designated Shareholder agrees severally to indemnify and hold harmless Insmed, the other Designated Shareholders, any underwriter retained by Insmed and each Person who controls Insmed, the other Designated Shareholders or such underwriter (within the meaning of Section 15 of the Securities Act) to the same extent as the foregoing indemnity from Insmed to the Designated Shareholders (including indemnification of their respective partners, directors, officers, Affiliates, stockholders, members, employees, trustees and Controlling Persons), but only to the extent that Liabilities arise out of or are based upon a statement or alleged statement or an omission or alleged omission that was made in reliance upon and in conformity with information with respect to such Designated Shareholder furnished in writing to Insmed by or on behalf of such Designated Shareholder expressly for use in such Disclosure Package, Registration Statement, Prospectus, Free Writing Prospectus or such amendment or supplement thereto, including, without limitation, the information furnished to Insmed pursuant to Section 7(b) hereof; provided, however, that the total amount to be indemnified by such Designated Shareholder pursuant to this Section 8(b) shall be limited to the net proceeds received by such Designated Shareholders in the offering to which such Disclosure Package, Registration Statement, Prospectus, Free Writing Prospectus or such amendment or supplement thereto relates.


 


(c) Conduct of Indemnification Proceedings


 


Any Person entitled to indemnification or contribution hereunder (the “Indemnified Party”) agrees to give prompt written notice to the indemnifying party (the “Indemnifying Party”) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to this Agreement; provided, however, that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any Liability that it may have to the Indemnified Party hereunder (except to the extent that the Indemnifying Party is materially prejudiced or otherwise forfeits substantive rights or defenses by reason of such failure).  If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such Indemnified Party.  Each Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the reasonable and documented out-of-pocket fees and expenses of such counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense of such action with counsel reasonably satisfactory to the Indemnified Party or (iii) the named parties to any such action (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and such parties have been advised by such counsel that either (x) representation of such Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct or (y) there may be one or more legal defenses available to the Indemnified Party which are different from or additional to those available to the Indemnifying Party.  In any of such cases, the Indemnifying Party shall not have the right to assume the defense of such action on behalf of such Indemnified Party, it being understood, however, that the Indemnifying Party shall not be liable for the reasonable and documented out-of-pocket fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all Indemnified Parties and all such reasonable and documented out-of-pocket fees and expenses shall be reimbursed as incurred.  No Indemnifying Party shall be liable for any settlement entered into without its written consent, which consent shall not be unreasonably withheld.  No Indemnifying Party shall, without the consent of such Indemnified Party, which consent shall not be unreasonably withheld, effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Party is a party and indemnity has been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability for claims that are the subject matter of such proceeding.


 


(d) Contribution


 


If the indemnification provided for in this Section 8 from the Indemnifying Party is unavailable to an Indemnified Party hereunder or insufficient to hold harmless an Indemnified Party in respect of any Liabilities referred to herein, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Liabilities in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such Liabilities, as well as any other relevant equitable considerations.  The relative faults of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action.  The amount paid or payable by a party as a result of the Liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 8(a), 8(b) and 8(c) hereof, any reasonable and documented out-of-pocket legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding; provided, that the total amount to be contributed by any Designated Shareholder shall be limited to the net proceeds (after deducting the underwriters’ discounts and commissions) received by such Designated Shareholder in the offering.


 


The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 8(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 in the immediately preceding paragraph.  No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution or indemnification from any Person who was not guilty of such fraudulent misrepresentation.


 


9. Rule 144


 


Insmed covenants that it shall take such action as may be required from time to time to enable such Designated Shareholder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such rule may be amended from time to time, or Regulation S under the Securities Act or(ii) any similar rules or regulations hereafter adopted by the Commission.  Insmed shall, upon the request of any Designated Shareholder, deliver to such Designated Shareholder a written statement as to whether it has complied with such requirements.


 


10. Miscellaneous


 


(a) Stock Splits, etc.


 


  The provisions of this Agreement shall be appropriately adjusted for any stock dividends, splits, reverse splits, combinations recapitalizations and the like occurring after the date hereof.


 


(b) Inconsistent Agreements


 


Insmed hereby represents and warrants that it has not previously entered into any agreement granting registration rights to any Person with respect to any securities of Insmed.  So long as any Registrable Securities or shares of Preferred Stock remain outstanding, Insmed shall not enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Designated Shareholders in this Agreement or grant any additional registration rights to any Person or with respect to any securities that are not Registrable Securities which rights are senior or on par with the rights granted in this Agreement without the prior written consent of the Designated Shareholders holding greater than 62.5% of the Registrable Securities then held by the Designated Shareholders.


 


(c) Remedies


 


The Designated Shareholders, in addition to being entitled to exercise all rights granted by law, including recovery of damages, shall be entitled to specific performance of their rights under this Agreement.  Insmed agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive in any action for specific performance the defense that a remedy at law would be adequate.


 


(d) Amendments and Waivers


 


Except as otherwise provided herein, the provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless consented to in writing by Insmed and the Majority Designated Shareholders; provided, however, that no amendment, modification, supplement, waiver or consent to depart from the provisions hereof shall be effective if such amendment, modification, supplement, waiver or consent to depart from the provisions hereof materially and adversely affects the substantive rights or obligations of one Designated Shareholder, or group of Designated Shareholders, without a similar and proportionate effect on the substantive rights or obligations of all Designated Shareholders, unless each such disproportionately affected Designated Shareholder consents in writing thereto.
