WARRANTHOLDERS RIGHTS AGREEMENT DATED AS OF JANUARY 17, 1997 AMONG PERINI CORPORATION AND THE INITIAL WARRANTHOLDERS LISTED ON THE SIGNATURE PAGES THEREOF
AND (2) A SECURITYHOLDERS AGREEMENT DATED AS OF JANUARY 17, 1997 AMONG PERINI CORPORATION AND THE SERIES B SHAREHOLDERS AND INITIAL WARRANTHOLDERS LISTED ON THE SIGNATURE PAGES THEREOF, A COPY OF EACH OF WHICH IS ON FILE WITH PERINI
CORPORATION.” 
  
 Any certificate for any Warrant Shares
issued at any time in exchange or in substitution for any certificate bearing such legend (except a new certificate issued upon completion of a public offering pursuant to a registration statement under the Securities Act) shall also bear such
legend unless, in the opinion of counsel selected by the holder of such certificate (who may be an employee of such holder) and reasonably acceptable to the Company, the securities represented thereby need no longer be subject to restrictions on
resale under the Securities Act. 
  
 (c) Any other provision of
this Agreement to the contrary notwithstanding, no transfer of any Restricted Securities other than pursuant to a Public Sale may be made to any Person unless such Person shall have agreed in writing with the Company that such Person, as a holder of
Restricted Securities, and the Restricted Securities it acquires shall be bound by and be entitled to the benefits of all the provisions of this Agreement applicable to such Restricted Securities (and upon such agreement such Person shall be
entitled to such benefits). Any purported transfer of Restricted Securities without compliance with the applicable provisions of this Agreement shall be void and of no effect, and the purported transferee shall have no rights as a holder of such
Restricted Securities or as a Warrant Securityholder under this Agreement. In the event of such non-complying transfer, the Company shall not transfer any such Restricted Securities on its books or recognize the purported transferee as a shareholder
or warrantholder, as the case may be, for any purpose, until all applicable provisions of this Agreement have been complied with. 
  
 SECTION 2.3. Permitted Transfers. The restrictions on transfer provided in Section 2.2(a) shall not be applicable to (i) any transfer in compliance
with federal and all applicable state securities laws to an Affiliate of the holder of Restricted Securities, from an Affiliate of such holder to such holder or between Affiliates of such holder (if any such Affiliate to whom shares of Restricted

any holder of Restricted Securities to such holder’s executors, administrators or testamentary trustees or (iii) any transfer to a trust the beneficiaries of which include only the holder of such Restricted Securities or such holder’s
spouse, parents, siblings or descendants (any 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	6	  	 









 
transferee referred to in (i), (ii) or (iii) above being referred to herein as a “Permitted Transferee”); provided that no such
transfer shall be made to any Permitted Transferee unless such Permitted Transferee shall have agreed in writing with the Company that such Permitted Transferee, as a holder of Warrants and any Warrant Shares it acquires upon the exercise of
Warrants, shall be bound by and be entitled to the benefits of all the provisions of this Agreement, and upon such agreement such Permitted Transferee shall be entitled to such benefits. 
  
 SECTION 2.4. No Inconsistent Agreements. The Company has not entered into and will not enter into any registration
rights agreement or similar arrangements the performance by the Company of the terms of which would in any manner conflict with, restrict or be inconsistent with the performance by the Company of its obligations under this Agreement. 
  
 ARTICLE III 
  
 REGISTRATION RIGHTS 
  
 SECTION 3.1 Shelf Registration. (a) As soon as practicable but in any event not later than the date (the “Filing Date”) that is
sixty (60) days after receipt by the Company at any time after the Earliest Exercise Date of a written request by the holder or holders of a majority of all outstanding Warrant Shares and Warrants (such majority determined, for purposes of this
Section 3.1, based on the aggregate number of Warrant Shares then outstanding plus the number of Warrant Shares for which any outstanding Warrants are then exercisable) (the “Initiating Holders”), the Company shall prepare and file
with the SEC a Registration Statement for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act (a “Shelf Registration”) registering the resale from time to time by the holders thereof of
all of the Registrable Securities upon and following exercise of the Warrants (the “Initial Shelf Registration”). The Registration Statement for any Shelf Registration shall be on Form S-3 or another appropriate form permitting
registration of such Registrable Securities for resale by such holders in the manner or manners designated by them (including, without limitation, one or more Underwritten Offerings). The Company shall use its reasonable efforts to cause the Initial
Shelf Registration to become effective under the Securities Act as promptly as is practicable and to keep the Initial Shelf Registration continuously effective under the Securities Act until the end of the Effectiveness Period. 
  
 (b) If the Initial Shelf Registration or any Subsequent Shelf Registration
(as defined below) ceases to be effective for any reason at any time during the Effectiveness Period (other than because all Registrable Securities shall have been sold or shall have ceased to be Registrable Securities), the Company shall use all
reasonable efforts to obtain the prompt withdrawal of any order suspending the 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	7	  	 









 
effectiveness thereof, and in any event shall within thirty days of such cessation of effectiveness amend the Shelf Registration in a manner reasonably
expected to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration covering all of the Registrable Securities (a “Subsequent Shelf Registration”). If a Subsequent Shelf
Registration is filed, the Company shall use all reasonable efforts to cause the Subsequent Shelf Registration to become effective as promptly as is practicable after such filing and to keep such Registration Statement continuously effective until
the end of the Effectiveness Period. 
  
 (c) The Company shall
supplement and amend the Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration, if required by the Securities Act, or if reasonably requested by
any holder of the Registrable Securities covered by such Registration Statement or by any Managing Underwriter of such Registrable Securities. 
  
 (d) Each Warrant Securityholder agrees that if it wishes to sell any Registrable Securities pursuant to a Shelf Registration and related Prospectus, it
will do so only in accordance with this Section 3.1(d). Each holder of Registrable Securities agrees to give written notice to the Company at least six Business Days prior to any intended distribution of Registrable Securities under the Shelf
Registration, which notice shall specify the date on which such holder intends to begin such distribution and any information with respect to such holder and the intended distribution of Registrable Securities by such holder required to amend or
supplement the Registration Statement with respect to such intended distribution of Registrable Securities by such holder; provided that no holder may give such notice unless such notice, together with notices given by other holders of
Registrable Securities joining in such notice or giving similar notices, covers at least 30,000 Warrant Shares. As promptly as is practicable after the date such notice is provided, and in any event within five Business Days after such date, the
Company shall either: 
  
 (i) (A) prepare and
file with the SEC a post-effective amendment to the Shelf Registration or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or any other required document, so that such Registration
Statement will not contain any 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, and so that, as thereafter delivered to purchasers of the
Registrable Securities being sold thereunder, such Prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; (B) provide each Notice Holder a copy of any documents filed pursuant to Section 3.1(d)(i)(A); and (C) inform each Notice Holder that the Company has complied with its 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	8	  	 









 
obligations in Section 3.1(d)(i)(A) and that the Registration Statement and related Prospectus may be used for the purpose of selling all or any of such
Registrable Securities (or that, if the Company has filed a post-effective amendment to the Shelf Registration which has not yet been declared effective, the Company will notify each Notice Holder to that effect, will use all reasonable efforts to
secure the effectiveness of such post-effective amendment and will immediately so notify each Notice Holder when the amendment has become effective); each Notice Holder will sell all or any or such Registrable Securities pursuant to the Shelf
Registration and related Prospectus only during the 45-day period commencing with the date on which the Company gives notice, pursuant to Section 3.1(d)(i)(C), that the Registration Statement and Prospectus may be used for such purpose (such 45-day
period is referred to as a “Selling Period”); each Notice Holder agrees that it will not sell any Restricted Securities pursuant to such Registration Statement or Prospectus after such Selling Period without giving a new notice of
intention to sell pursuant to Section 3.1(d) hereof and receiving a further notice from the Company pursuant to Section 3.1(d)(i)(C) hereof; or 
  
 (ii) if, in the judgment of the Company, it is advisable to suspend use of the Prospectus for a period of time due to pending material
corporate developments or similar material events that have not yet been publicly disclosed and as to which the Company believes public disclosure will be prejudicial to the Company, the Company shall deliver a certificate in writing, signed by its
Chief Executive Officer, Chief Financial Officer or General Counsel, to the Notice Holders, the Special Counsel and the Managing Underwriters, if any, to the effect of the foregoing and, upon receipt of such certificate, each such Notice
Holder’s Selling Period will not commence until such Notice Holder’s receipt of copies of the supplemented or amended Prospectus provided for in Section 3.1(d)(i)(A) hereof, or until it is advised in writing by the Company that the
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. The Company will use all reasonable efforts to ensure that the use of the
Prospectus may be resumed, and the Selling Period will commence, upon the earlier of (x) public disclosure of such pending material corporate development or similar material event or (y) a determination by the Company that, in the judgment of the
Company, public disclosure of such material corporate development or similar material event would not be prejudicial to the Company. Notwithstanding the foregoing, the Company shall not under any circumstances be entitled to exercise its right under
this Section 3.1(d) to defer the commencement of a Selling Period more than one time in any three-month period or two times in any twelve-month period, and the period in which a Selling Period is suspended shall not exceed fifteen days unless the
Company shall deliver to such Notice Holders a second certificate to the effect set forth above, which 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	9	  	 









 
shall have the effect of extending the period during which such Selling Period is deferred by up to an additional fifteen days, or such shorter period of
time as is specified in such second certificate. In no event shall the Company be permitted to extend the period during which such Selling Period is deferred from and after the date a Notice Holder provides notice to the Company in accordance with
this Section 3.1(d) of its intention to distribute Registrable Securities (a “Deferral Period”) beyond such 30-day period. 
  
 SECTION 3.2. Registration Procedures. In connection with the Company’s registration obligations under Section 3.1 hereof, the Company shall
effect such registrations to permit the sale of the Registrable Securities in accordance with the intended method or methods of disposition thereof, and pursuant thereto the Company shall as expeditiously as possible: 
  
 (a) Prepare and file with the SEC a Registration Statement or Registration
Statements on any appropriate form under the Securities Act available for the sale of the Registrable Securities by the holders thereof in accordance with the intended method or methods of distribution thereof, and use its reasonable efforts to
cause each such Registration Statement to become effective and remain effective as provided herein; provided, that before filing any such Registration Statement or Prospectus or any amendments or supplements thereto (other than documents that
would be incorporated or deemed to be incorporated therein by reference and that the Company is required by applicable securities laws or stock exchange requirements to file) the Company shall furnish to the Initial Warrantholders, the Initiating
Holders, the Special Counsel and the Managing Underwriters of such offering, if any, copies of all such documents proposed to be filed, which documents will be subject to the review of the Initial Warrantholders, the Initiating Holders, the Special
Counsel and such Managing Underwriters, and the Company shall not file any such Registration Statement or amendment thereto or any Prospectus or any supplement thereto (other than such documents which, upon filing, would be incorporated or deemed to
be incorporated by reference therein and that the Company is required by applicable securities laws or stock exchange requirements to file) to which the holders of a majority of the Registrable Securities covered by such Registration Statement, the
Initial Warrantholders, the Initiating Holders or the Special Counsel shall reasonably object in writing within two full Business Days. 
  
 (b) Prepare and file with the SEC such amendments and post-effective amendments to each Registration Statement as may be necessary to keep such
Registration Statement continuously effective for the applicable period specified in Section 3.1; cause the related Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any
similar provisions then in force) under the Securities Act; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with
the 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	10	  	 









 
intended methods of disposition by the sellers thereof set forth in such Registration Statement as so amended or such Prospectus as so supplemented.

  
 (c) Notify the selling Warrant Securityholders, the Initial
Warrantholders, the Initiating Holders, the Special Counsel and the Managing Underwriters, if any, promptly, and (if requested by any such person) confirm such notice in writing, (i) when a Prospectus, any Prospectus supplement, a Registration
Statement or a post-effective amendment to a Registration Statement has been filed with the SEC, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the SEC or any
other federal or state governmental authority for amendments or supplements to a Registration Statement or related Prospectus or for additional information, and of the contents of such request, (iii) of the issuance by the SEC or any other federal
or state governmental authority of any stop order suspending the effectiveness of a Registration Statement or the initiation or threatening of any proceedings for that purpose, (iv) of the receipt by the Company 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 proceeding for such purpose, (v) of the existence of any fact or happening
of any event which makes any statement of a material fact in such Registration Statement or related 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 or 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 the Prospectus, it will not contain any untrue statement of a material fact or omit to state any 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, provided that the Company shall not be required to disclose such fact or event if such fact or event has not been publicly
disclosed, and (vi) of the Company’s determination that a post-effective amendment to a Registration Statement would be appropriate. 
  
 (d) Use all reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement, or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest possible moment. 
  
 (e) If reasonably requested by the Initial Warrantholders, the Initiating Holders, the Special Counsel, the Managing
Underwriters, if any, or the holders of a majority of the Registrable Securities being sold, (i) promptly incorporate in a Prospectus supplement or post-effective amendment to a Registration Statement such information as the Initial Warrantholders,
the Initiating Holders, the Special 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	11	  	 









 
Counsel, the Managing Underwriters, if any, or such holders, in connection with any offering of Registrable Securities, agree should be included therein as
required by applicable law, and (ii) make all required filings of such Prospectus supplement or such post-effective amendment as promptly as is practicable after the Company has received notification of the matters to be incorporated in such
Prospectus supplement or post-effective amendment; provided, that the Company shall not be required to take any actions under this Section 3.2(e) that are not, in the reasonable opinion of counsel for the Company, in compliance with or
required by applicable law. 
  
 (f) Furnish to each selling
Warrant Securityholder, the Special Counsel, each Initial Warrantholder and each Managing Underwriter, if any, without charge, at least one conformed copy of the Registration Statement or Statements and any amendment thereto, including financial
statements but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference and all exhibits (unless requested in writing by such Warrant Securityholder, Special Counsel, Initial Warrantholder or Managing
Underwriter). 
  
 (g) Deliver to each selling holder of
Registrable Securities, the Special Counsel, the Initial Warrantholders and each Managing Underwriter, if any, in connection with any offering of Registrable Securities, without charge, as many copies of the Prospectus or Prospectuses relating to

by each of the selling holders of Registrable Securities and the underwriters, if any, in connection with any offering and sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto. 
  
 (h) Prior to any public offering of Registrable Securities, to register or
qualify or cooperate with the selling Warrant Securityholders, the Managing Underwriters, if any, and the Special Counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any selling Warrant Securityholder or Managing Underwriter reasonably requests in writing to the Company; keep each such
registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective and do any and all other acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by the applicable Registration Statement; provided, that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or
(ii) take any action that would subject it to general service of process in suits or to taxation in any such jurisdiction where it is not then so subject. 
  


					
	 	 	 	  	[EXECUTION COPY]

 (i) Cause the Registrable Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the United States, except as may be required solely as a consequence of the nature of a selling holder of Registrable Securities, in which case the Company will cooperate in
all reasonable respects with the filing of such Registration Statement and the granting of such approvals, as may be necessary to enable the selling holder or holders thereof or the Managing Underwriters, if any, to consummate the disposition of
such Registrable Securities. 
  
 (j) During any Selling Period
(other than during a Deferral Period), immediately upon the existence of any fact or the occurrence of any event as a result of which a Registration Statement shall 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, or a Prospectus shall 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, promptly prepare and file a post-effective amendment to each Registration Statement or a supplement to the related Prospectus or any document
incorporated therein by reference or file any other required document (such as a Current Report on Form 8-K) that would be incorporated by reference into the Registration Statement so that the Registration Statement shall 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 so that the Prospectus will not contain any untrue statement of a material fact or omit to
state any 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, as thereafter delivered to the
purchasers of the Registrable Securities being sold thereunder, and, in the case of a post-effective amendment to a Registration Statement, use all reasonable efforts to cause it to become effective as promptly as is practicable.

Offering, an underwriting agreement in form, scope and substance as is customary in Underwritten Offerings) and take all such other actions in connection therewith (including, in the event of an underwritten offering, those reasonably requested by

“comfort” letters in connection with Underwritten Offerings; and (iv) deliver such documents and certificates as may be reasonably requested by the holders of a majority of the Registrable Securities being sold, the Special Counsel and the
Managing Underwriters, if any, to evidence the continued validity of the representations and warranties of the Company and its subsidiaries made pursuant to clause (i) above and to evidence compliance with any customary conditions contained in the
underwriting agreement or other agreement entered into by the Company. 
  
 (l) If requested in connection with a disposition of Registrable Securities pursuant to a Registration Statement, make available for inspection by a representative of the holders of Registrable Securities being sold, any Managing
Underwriter participating in any disposition of Registrable Securities, if any, and any attorney or accountant retained by such selling holders or underwriter, financial and other records, pertinent corporate documents and properties of the Company

 (m) Comply with all applicable rules and regulations of the SEC and make

	 	 	 	  	[EXECUTION COPY]
	 	 	14	  	 









 
after the effective date of a Registration Statement, which statements shall cover said 12-month periods. 
  
 (n) Cooperate with the selling Warrant Securityholders to facilitate the
timely preparation and delivery of certificates representing Registrable Securities to be sold and not bearing any restrictive legends; and enable such Registrable Securities to be in such denominations and registered in such names as the selling
Warrant Securityholders may request. 
  
 (o) Use all reasonable
efforts to provide a CUSIP number for the Registrable Securities not later than the effective date of the registration. 
  
 (p) Cause all Registrable Securities covered by the Registration Statement to be listed on each securities exchange or quotation system on which the
Company’s Common Stock is then listed no later than the date the Registration Statement is declared effective and, in connection therewith, to the extent applicable, to make such filings under the Exchange Act (e.g., the filing of a
Registration Statement on Form 8-A) and to have such filings declared effective thereunder. 
  
 (q) Cooperate and assist in any filings required to be made with the National Association of Securities Dealers, Inc. 
  
 (r) Provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by such registration statement from and after
a date not later than the effective date of such Registration Statement. 
  
 SECTION 3.3. Holder’s Obligations. (a) Each holder of Registrable Securities agrees, by becoming a transferee of any Registrable Securities, that no holder of Registrable Securities shall be entitled to
sell any of such Registrable Securities pursuant to a Registration Statement or to receive a Prospectus relating thereto, unless such holder has furnished the Company with the notice required pursuant to Section 3.1(d) hereof (including the
information required to accompany such notice) and, promptly after the Company’s request, such other information regarding such holder and the distribution of such Registrable Securities as the Company may from time to time reasonably request.
The Company may exclude from such registration the Registrable Securities of any holder who does not furnish such information provided above for so long as such information is not so furnished. Each holder of Registrable Securities as to which any
Registration Statement is being effected agrees promptly to furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such holder not misleading. Any sale of any
Registrable Securities by any holder shall constitute a representation and warranty by such holder that the information relating to such holder and its plan of distribution is as set forth in the Prospectus delivered by such holder in connection
with such disposition, that such Prospectus 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	15	  	 









 
does not as of the time of such sale contain any untrue statement of a material fact relating to such holder or its plan of distribution and that such
Prospectus does not as of the time of such sale omit to state any material fact relating to such holder or its plan of distribution necessary to make the statements in such Prospectus, in light of the circumstances under which they were made, not
misleading. 
  
 (b) The Company agrees (x) that if any holder of
Registrable Securities shall send a written notice to the Company of an intended distribution of Registrable Securities under the Shelf Registration pursuant to Section 3.1(d), the Company shall not to sell, make any short sale of, loan, grant any
option for the purchase of, effect any public sale or distribution of or otherwise dispose of its equity securities or securities convertible into or exchangeable or exercisable for any of such securities during the period from first day of the
applicable Selling Period until the date that is 90 days after the date when such holder shall have made such distribution of Registrable Securities under the Shelf Registration, as the holder or managing underwriter (in the case of an Underwritten
Offering) shall advise the Company (provided that if the holder or managing underwriter shall fail to advise the Company of any such date prior to the end of the applicable Selling Period, such period shall end on the last day of the
applicable Selling Period), except (i) as part of such registration, (ii) pursuant to registrations on Form S-4 or S-8 or any successor or similar forms thereto or (iii) as otherwise permitted by the managing underwriter of such offering (if any),
and (y) to use all reasonable efforts to cause each holder of its equity securities or any securities convertible into or exchangeable or exercisable for any of such securities, in each case purchased from the Company at any time after the date of
this Agreement (other than in a public offering) to agree not to sell, make any short sale of, loan, grant any option for the purchase of, effect any public sale or distribution of or otherwise dispose of such securities during such period except as
part of such underwritten registration; provided that no holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters other than
representations and warranties regarding such holder and such holder’s intended method of distribution. 
  
 SECTION 3.4. Registration Expenses. All fees and expenses incident to the Company’s performance of or compliance with this Agreement shall be
borne by the Company whether or not any of the Registration Statements become effective. Such fees and expenses shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (x) with
respect to filings required to be made with the National Association of Securities Dealers, Inc. and (y) of compliance with federal securities or Blue Sky laws (including, without limitation, fees and disbursements of Special Counsel in connection
with Blue Sky qualifications of the Registrable Securities laws of such jurisdictions as the Managing Underwriters, if any, or holders of a majority of the Registrable Securities being sold may designate), (ii) printing expenses (including, without
limitation, expenses of 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	16	  	 









 
printing certificates for Registrable Securities in a form eligible for deposit with The Depositary Trust Company and of printing prospectuses if the
printing of prospectuses is requested by the Special Counsel or the holders of a majority of the Registrable Securities included in any Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) reasonable fees and disbursements
of counsel for the Company and the Special Counsel in connection with the Shelf Registration, (v) fees and disbursements of all independent certified public accountants referred to in Section 3.2(k)(iii) hereof (including the expenses of any special
audit and “comfort” letters required by or incident to such performance) and (vi) Securities Act liability insurance obtained by the Company in its sole discretion. In addition, the Company shall pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit, the fees and expenses incurred in connection with the listing of the securities to be registered on
any securities exchange on which similar securities issued by the Company are then listed and the fees and expenses of any person, including special experts, retained by the Company. Notwithstanding the provisions of this Section 3.4, each seller of
Registrable Securities shall pay all registration expenses to the extent the Company is prohibited by applicable Blue Sky laws from paying for or on behalf of such seller of Registrable Securities. 
  
 SECTION 3.5. Indemnification. (a) The Company agrees to indemnify and
hold harmless each holder of Registrable Securities whose Registrable Securities are covered by any registration statement, its directors and officers and each other Person, if any, who controls such holder within the meaning of the Securities Act,
against any losses, claims, damages or liabilities, joint or several, to which any such indemnified party may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the
Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company will reimburse each such indemnified party for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim,
liability, action or proceeding; provided that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon
an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such holder specifically for use in the preparation thereof. In addition, the Company shall 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	17	  	 









 
indemnify any underwriter of such offering and each other Person, if any, who controls any such underwriter within the meaning of the Securities Act in
substantially the same manner and to substantially the same extent as the indemnity herein provided to each Indemnified Party. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such holder
or any such director, officer, underwriter or controlling person and shall survive the transfer of such securities by such holder. 
  
 (b) Each prospective seller of Registrable Securities hereunder shall indemnify and hold harmless (in the same manner and to the same extent as set forth
in subdivision (a) of this Section 3.5) the Company, each director of the Company, each officer of the Company and each other person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged
statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereof, if such statement or alleged statement or
omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such seller specifically for use in the preparation of such registration statement, preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement. Any such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling person and
shall survive the transfer of such securities by such seller. The amount payable by any prospective seller of Registrable Securities with respect to the indemnification set forth in this subsection (b) in connection with any offering of Registrable
Securities will not exceed the amount of the gain realized by such prospective seller pursuant to such offering. 
  
 (c) Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the
preceding subdivisions of this Section 3.5, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided that the
failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding subdivisions of this Section 3.5, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may
exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that the indemnifying party may wish, with
counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not 

  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	18	  	 









 
be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof. No
indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement of any such action 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 to such claim or litigation. No indemnified party shall consent to entry of any judgment or enter into any settlement of any such action the defense of which has been assumed by an
indemnifying party without the consent of such indemnifying party. 
  
 (d) If the indemnification provided for in the preceding subdivisions of this Section 3.5 is unavailable to an indemnified party in respect of any expense, loss, claim, damage or liability referred to therein, 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 expense, loss, claim, damage or liability (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the holder or underwriter, as the case may be, on the other from the distribution of the Registrable Securities or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the holder or underwriter, as the case may be, on the
other in connection with the statements or omissions which resulted in such expense, loss, damage or liability, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the holder or
underwriter, as the case may be, on the other in connection with the distribution of the Registrable Securities shall be deemed to be in the same proportion as (i) the product of the Exercise Price (as defined in the Warrants) multiplied by the
number of Registrable Securities subject to the relevant distribution bears to (ii) the gain realized by the selling holder or the underwriting discounts and commissions received by the underwriter, as the case may be. The relative fault of the
Company on the one hand and of the holder or underwriter, as the case may be, on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission to state a material
fact relates to information supplied by the Company, by the holder or by the underwriter and parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided that the
foregoing contribution agreement shall not inure to the benefit of any indemnified party if indemnification would be unavailable to such indemnified party by reason of the proviso contained in the first sentence of subdivision (a) of this Section
3.5, and in no event shall the obligation of any indemnifying party to contribute under this subdivision (d) exceed the amount that such indemnifying party would have been obligated to pay by way of indemnification if the indemnification provided
for under subdivisions (a) or (b) of this Section 3.5 had been available under the circumstances. 
  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	19	  	 









 The Company and the holders of Registrable Securities agree that it would not be just and equitable if
contribution pursuant to this subdivision (d) were determined by pro rata allocation (even if the holders and any underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding paragraph and subdivision (c) of this Section 3.5. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in
the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or
claim. 
  
 Notwithstanding the provisions of this subdivision (d),
no holder of Registrable Securities or underwriter shall be required to contribute any amount in excess of the amount by which (i) in the case of any such holder, the gain realized by such holder from the sale of Registrable Securities or (ii) in
the case of an underwriter, the total price at which the Registrable Securities purchased by it and distributed to the public were offered to the public exceeds, in any such case, the amount of any damages that such holder or underwriter has
otherwise been required to pay by reason of such untrue or alleged untrue statement or omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. 
  
 SECTION 3.6. Rule 144; Rule 144A; Form S-3. (a) The Company will file all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the Commission thereunder and will
take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the Commission. Upon the request of any holder of Registrable
Securities, the Company will deliver to such holder a written statement as to whether it has complied with such requirements. The Company further covenants that it will cooperate with any holder of Registrable Securities and take such further
reasonable action as any holder of Registrable Securities may reasonably request (including, without limitation, making such reasonable representations as any such holder may reasonably request), all to the extent required from time to time to
enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 and Rule 144A under the Securities Act. 
  


					
	 	 	 	  	[EXECUTION COPY]
	 	 	20	  	 









 (b) For so long as any shares of Registrable Securities are restricted securities within the meaning of
Rule 144(a)(3) under the Securities Act, the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) of the Exchange Act, make available to any holder of Registrable Securities in connection
with the sale of such holder Registrable Securities and any prospective purchaser of Registrable Securities from such, in each case upon request, the information specified in, and meeting the requirements of, Rule 144A(d)(4) under the Securities
Act. 
  
 (c) The Company shall file the reports required to be
filed by it under the Exchange Act and shall comply with all other eligibility requirements for use of Form S-3 set forth in the instructions to Form S-3 (other than Registrant Requirement A.5).
