(b)     Any director nominee designated by Sponsor Stockholder in accordance with this Section 3.01 shall only be required to satisfy eligibility requirements, as reasonably determined by the Nominating and Governance Committee, that are generally applicable to all nominees to the Board.  Notwithstanding anything to the contrary herein, Sponsor Stockholder’s director nominee designation and other governance rights are subject to compliance with applicable laws, including antitrust laws.

Company with accurate and complete information relating to Sponsor Stockholder and such nominee that may be required to be disclosed by the Company under the Securities Act or the Exchange Act, including such information required to be furnished by the Company with respect to such nominee in a proxy statement pursuant to Rule 14a-101 promulgated under the Exchange Act, and the nationality of such nominee.  In addition, Sponsor Stockholder shall cause such nominee to (i) complete and execute the Company’s director and officer questionnaire prior to the Company’s filing of the preliminary proxy statement for the applicable stockholder meeting or at such other time as may be reasonably requested by the Company, (ii) consent to customary background checks and credit reviews by the Company, (iii) execute an acknowledgement that such nominee will agree to abide by the terms of the applicable governance documents of the Company, including the corporate governance guidelines, charter, bylaws, committee charters or similar agreements in effect from time to time (such acknowledgement being the same in form and substance as that executed by other director candidates), and (iv) take any other actions as may be necessary and customary for onboarding of directors and generally applicable to all directors and director candidates of the Company, including such additional documentation that may be necessary to address a lack of certain security clearances.  In addition, if the Company has a form of director confidentiality agreement, each nominee shall be required to execute such agreement.

Section 6.02.          Demand Registration.

(a)          Following the Lock-up Release Date, if at any time the Shelf Registration Statement pursuant to Section 6.01 is not available for the resale of the Registrable Securities, including if for any reason the Company is ineligible to maintain or use a Shelf Registration Statement, the Company shall use reasonable best efforts to (as promptly as reasonably practicable and, in any event, within (i) 45 days in the case of a Registration Statement on Form S-3 or (ii) 60 days in the case of a Registration Statement on Form S-1) following the written request of Sponsor Stockholder for Registration under the Securities Act of all or part of the Registrable Securities (a “Demand Request”), file a Registration Statement with the SEC (a “Demand Registration Statement”) with respect to resales of the Registrable Securities pursuant to Sponsor Stockholder’s intended method of distribution thereof, and shall, subject to the terms of this Article VI, use its reasonable best efforts to cause such Demand Registration Statement to be declared effective under the Securities Act (promptly and, in any event, no later than 60 days after such filing) and, if required, to qualify under the “blue sky” laws of such jurisdictions as Sponsor Stockholder or any underwriter reasonably requests; provided that such Demand Registration Statement shall be filed on (A) Form S-3, if the Company is then S-3 Eligible, or (B) any other appropriate form under the Securities Act for the type of offering contemplated by Sponsor Stockholder, if the Company is not then S-3 Eligible.  Each Demand Request shall specify the Registrable Securities to be Registered, their aggregate amount, and the intended method or methods of distribution thereof.  Sponsor Stockholder agrees to provide the Company with such information in connection with a Demand Request as may be reasonably requested by the Company to ensure that the Demand Registration Statement complies with the requirements of the

Securities Act.  Notwithstanding anything in this Agreement to the contrary, the Company shall only be obligated to use reasonable best efforts to file and cause up to three Demand Registration Statements to be declared effective under the Securities Act within any 365-day period pursuant to this Section 6.02.

(b)          The Company shall be deemed to have effected a Demand Registration for purposes of this Section 6.02, Section 6.03(a) and Section 6.04(a) if the Demand Registration Statement becomes effective by the SEC and remains effective until the earlier of (i) 90 days after the effective date or (ii) such time as all Registrable Securities covered by such Registration Statement have been sold or withdrawn in accordance with this Section 6.02, or if such Registration Statement relates to an Underwritten Offering (as defined below), such longer period as, in the opinion of outside legal counsel for the underwriter or underwriters, a Prospectus is required by law to be delivered in connection with sales of Registrable Securities by an underwriter or dealer (the applicable period, the “Demand Period” ); provided that (i) if, during the Demand Period, such Registration or the successful completion of the relevant sale is prevented by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court, or a Blackout Period or the need to update or supplement the Registration Statement, the Demand Period shall be extended on a day-for-day basis by the number of days such Registration or successful completion is prevented and (ii) no Demand Registration shall be deemed to have been effective for purposes of Section 6.03(a) and Section 6.04(a) if the conditions to closing specified in the underwriting agreement, if any, entered into in connection with any Underwritten Offering pursuant to such Demand Registration are not satisfied other than by reason of a wrongful act, misrepresentation or breach of such applicable underwriting agreement by Sponsor Stockholder.

Section 6.03.          Registration Obligations.

(a)          Notwithstanding anything to the contrary set forth in Section 6.01 or Section 6.02, the Company shall not be obligated to prepare, file and cause to become effective (i) more than three Demand Registration Statements within any 365-day period or (ii) any Demand Registration Statement in respect of Registrable Securities if the expected proceeds from the sale thereof is less than $50,000,000 (unless, in the case of the foregoing clause (ii), Sponsor Stockholder is proposing to sell all of its remaining Registrable Securities).

(b)          Any Takedown Request or Demand Request may be revoked by notice from Sponsor Stockholder to the Company at any time prior to the effective date of the corresponding Takedown Prospectus Supplement or Demand Registration Statement; provided that Sponsor Stockholder reimburses the Company for all reasonable and documented out-of-pocket expenses incurred by the Company in connection with such revoked Takedown Request or Demand Request (other than any expenses incurred by the Company in connection with a Takedown Request or Demand Request revoked by Sponsor Stockholder in connection with a Blackout Period or at a time one or more executive officers of the Company has determined the Company is entitled to impose a Blackout Period as set forth in Section 6.03(c)).

(c)          Notwithstanding anything in this Agreement to the contrary, the Company shall be entitled to postpone and delay, for reasonable periods of time not in excess of 60 days in the aggregate in any 12-month period (a “Blackout Period”), the filing or effectiveness of any Takedown Prospectus Supplement or Demand Registration Statement or the offer or sale of any Registrable Securities thereunder if one or more of the Executive Chairman, Chief Executive Officer, Chief Financial Officer or Chief Legal Officer of the Company shall determine in good faith that such filing or effectiveness or such offering or sale of any Registrable Securities thereunder, as applicable, would (i) impede, delay or otherwise interfere with any pending or contemplated material acquisition, disposition, corporate reorganization or other similar material transaction involving the Company, (ii) based upon advice from a nationally recognized investment banker or financial advisor to the Company, materially and adversely impede, delay or otherwise interfere with any pending or contemplated financing, offering or sale of any class of securities by the Company, (iii) require Adverse Disclosure or (iv) have a material adverse effect on the Company.  Upon notice by the Company to Sponsor Stockholder of any such determination, Sponsor Stockholder shall, except as required by applicable law, including any disclosure obligations under Section 13 of the Exchange Act, keep the fact of any such notice strictly confidential, and during any Blackout Period, promptly halt any offer, sale, trading or Transfer by it of any Common Stock for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated by written notice by the Company to Sponsor Stockholder) and promptly halt any use, publication, dissemination or distribution of any Prospectus or prospectus supplement covering such Registrable Securities for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company) and, if so directed by the Company, shall deliver to the Company any copies then in its possession of any such Prospectus or prospectus supplement.

Section 6.04.          Underwritten Offering.

(a)          Following the Lock-up Release Date, at any time after the Shelf Registration Statement required pursuant to Section 6.01 becomes effective, or as part of a Demand Request in accordance with Section 6.02, Sponsor Stockholder may deliver a written notice to the Company (the “Underwritten Offering Notice”) specifying that the sale of some or all of the Registrable Securities subject to such Shelf Registration Statement or Demand Registration Statement is intended to be conducted through an underwritten offering (the “Underwritten Offering”); provided, however, that Sponsor Stockholder may not, without the Company’s prior written consent, (i) launch an Underwritten Offering the anticipated gross proceeds of which are expected to be less than $50,000,000 (unless Sponsor Stockholder is proposing to sell all of its remaining Registrable Securities), (ii) launch more than three Underwritten Offerings within any 365-day period or (iii) launch an Underwritten Offering within a Blackout Period.

(b)          In the event of an Underwritten Offering, Sponsor Stockholder shall select the managing underwriter(s) to administer the Underwritten Offering; provided that the choice of such managing underwriter(s) shall be subject to the consent of the Company, which consent is not to be unreasonably withheld, delayed or

conditioned.  The Company and Sponsor Stockholder will enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such offering.

(c)          If, pursuant to Section 6.03(c), the Company defers any Registration of Registrable Securities in response to an Underwritten Offering Notice, Sponsor Stockholder shall be entitled to withdraw such Underwritten Offering Notice and if it does so, such request shall not be treated for any purpose as the delivery of an Underwritten Offering Notice pursuant to Section 6.04(a).

Section 6.05.          Piggy-Back Registration.  If, following the Lock-up Release Date, the Company at any time proposes or is required to Register any Common Stock under the Securities Act on its behalf or on behalf of any of its stockholders (including Sponsor Stockholder), on a form and in a manner that would permit Registration of the Registrable Securities (other than in connection with (i) dividend reinvestment plans, (ii) rights offerings, (iii) a Registration Statement on Form S-4 or Form S-8 or any similar successor form or (iv) a Shelf Registration Statement pursuant to which only the initial purchasers and subsequent transferees of debt securities of the Company or any of its Subsidiaries that are convertible or exchangeable for Common Stock and that are initially issued pursuant to Rule 144A and/or Regulation S (or any successor provisions) of the Securities Act may resell such notes and sell shares of Common Stock into which such notes may be converted or exchanged; provided, that the Company may not effect any offering or Shelf Take-Down with respect to shares of Common Stock on such initial Shelf Registration Statement unless the Company provides Sponsor Stockholder with a Piggy-Back Company Notice (as defined below) with respect to (A) such offering or Shelf Take-Down or (B) a concurrent Registration Statement) then the Company shall give Sponsor Stockholder prompt written notice (a “Piggy-Back Company Notice”) of its intent to do so not less than 15 Business Days prior to the contemplated filing date for such Registration Statement.  Upon the written request of Sponsor Stockholder (a “Piggy-Back Request”), given within five Business Days following the time that Sponsor Stockholder was given any such written notice (which Piggy-Back Request shall specify the number of Registrable Securities requested to be Registered on behalf of Sponsor Stockholder) (the “Piggy-Back Securities”), the Company shall include in such Registration Statement, subject to the provisions of this Section 6.05 and, in the case of a Registration on behalf of any of the Company’s stockholders, subject to the rights of such stockholders, the number of Registrable Securities set forth in such Piggy-Back Request.

Section 6.06.          Cutbacks.  In the event that (x) the Company proposes or is required (other than pursuant to a Takedown Request or Demand Request) to Register Common Stock in connection with an Underwritten Offering, (y) Sponsor Stockholder has made a Piggy-Back Request in accordance with Section 6.05 with respect to such offering and (z) a nationally recognized investment banking firm selected by the Company to act as managing underwriter thereof reasonably and in good faith shall have advised the Company, Sponsor Stockholder or any other holder of Common Stock intending to offer Common Stock in the offering, as applicable (each, an “Other Holder”), in writing that, in its opinion, the inclusion in the Registration Statement of

some or all the shares of Common Stock sought to be Registered by the Company, Sponsor Stockholder or the Other Holder(s) would adversely affect the price or success of the offering, the Company shall include in such Registration Statement such number of shares of Common Stock as the Company is reasonably advised can be sold in such offering without such an effect (the “Maximum Number”) as follows and in the following order of priority:

(a)          if such Registration is by the Company for its own account, (i) first, such number of shares of Common Stock as the Company proposes to Register for its own account, (ii) second, to the extent the number of shares of Common Stock to be included in the Registration pursuant to clause (i) is less than the Maximum Number, such number of Piggy-Back Securities as Sponsor Stockholder proposes to be included pursuant to a Piggy-Back Request, and (iii) third, to the extent the number of shares of Common Stock to be included in the Registration pursuant to the foregoing clauses (i) and (ii) is less than the Maximum Number, such number of shares of Common Stock as all Other Holders request to be included for their own account (with such number of shares allocated pro rata among the Other Holders in proportion to their respective beneficial ownership of such shares); or

(b)          if such Registration is pursuant to the Demand Registration rights of one or more Other Holders, (i) first, such number of shares of Common Stock as such Other Holder(s) and Sponsor Stockholder propose to be included (with such number of shares allocated pro rata among the Other Holder(s) and Sponsor Stockholder in proportion to their respective beneficial ownership of such shares) and (ii) second, to the extent the number of shares of Common Stock to be included in the Registration pursuant to clause (i) of this subparagraph (b) is less than the Maximum Number, such number of shares of Common Stock as the Company requests to be included.

Section 6.07.          Rule 144A and Regulation S Sales.  Following the Lock-up Release Date, Sponsor Stockholder shall, in accordance with Rule 144A and/or Regulation S under the Securities Act (or any successor provisions), have analogous rights to sell its Registrable Securities in a marketed offering under Rule 144A and/or Regulation S (or any successor provisions) under the Securities Act through one or more initial purchasers on a firm-commitment basis, using procedures that are substantially equivalent to those specified in this Article VI.  The Company agrees to use its reasonable best efforts to cooperate to effect any such sales under such Rule 144A and/or Regulation S (or any successor provisions).  Except as may be required by Rule 144A and/or Regulation S (or any successor provision), nothing in this Section 6.07 shall impose any additional or more burdensome obligations on the Company than would apply under this Article VI, in each case, mutatis mutandis in respect of a Registered Underwritten Offering (including the estimated gross proceeds minimum set forth in Section 6.04(a)), or require that the Company take any actions that it would not be required to take in an Underwritten Offering of such Registrable Securities.

Section 6.08.          Rule 144.

(a)          With a view to making available the benefits of Rule 144 to Sponsor Stockholder, the Company agrees that, for so long as Sponsor Stockholder owns Registrable Securities, the Company will use its reasonable best efforts to:  (i) make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the Lock-up Release Date; and (ii) following the Lock-up Release Date, for so long as a Sponsor Stockholder owns any Restricted Securities, furnish to Sponsor Stockholder upon written request a written statement by the Company as to its compliance with the reporting requirements of the Exchange Act.

(b)          For so long as Sponsor Stockholder owns Registrable Securities, the Company will use reasonable best efforts to take such further necessary action as any holder of Registrable Securities may reasonably request in connection with the removal of any restrictive legend on the Registrable Securities being sold, all to the extent required from time to time to enable Sponsor Stockholder to sell the Restricted Securities following the Lock-up Release Date without Registration under the Securities Act within the limitations of the exemption provided by Rule 144.

Section 6.09.          Holdback Agreements.

(a)          To the extent requested in writing by the managing underwriter or underwriters of any Underwritten Offering and to the extent Sponsor Stockholder signs a lock-up agreement (for shares of Common Stock not covered in the Underwritten Offering other than in the case of an Underwritten Offering of all Registrable Securities held by Sponsor Stockholder), the Company agrees not to, and shall use reasonable best efforts to obtain agreements (in the underwriters’ customary form) from its directors and executive officers (including any deemed “officers” under Section 16 of the Exchange Act) not to, directly or indirectly offer, Transfer or pledge, or contract to Transfer or pledge, any equity securities of the Company, during the 90 days  beginning on the pricing date of such Underwritten Offering (except as part of such Underwritten Offering or any Transfer pursuant to Registrations on Form S-8 or Form S-4) unless Sponsor Stockholder and the managing underwriter or underwriters otherwise agree to a shorter period.  Each Person subject to the restrictions of the preceding sentence shall receive the benefit of any shorter “lock-up” period or permitted exceptions agreed to by Sponsor Stockholder and the managing underwriter or underwriters for any Underwritten Offering and the terms of such lock-up agreements shall govern such Person in lieu of the preceding sentence.

(b)          To the extent requested in writing by the underwriter(s) or exchanging bank(s) in connection with a debt-for-equity exchange by Jacobs with respect to its Common Stock, the Company agrees not to, and shall use reasonable best efforts to obtain agreements (in the underwriters’ or banks’ customary form) from their respective directors and executive officers not to, directly or indirectly offer, Transfer or pledge, or contract to Transfer or pledge, any equity securities of the Company, during the 90 days beginning on the pricing date for such debt-for-equity exchange unless the underwriters or banks otherwise agree to a shorter period.  Each Person subject to the restrictions of the preceding sentence shall receive the benefit of any shorter “lock-up” period or permitted exceptions agreed to by the underwriters or banks for the debt-for-equity

exchange and the terms of such lock-up agreements shall govern such Person in lieu of the preceding sentence.  For the avoidance of doubt, the agreements described in the first sentence of this Section 6.09(b) shall not apply to restrict Sponsor Stockholder or any Common Stock held by Sponsor Stockholder.

Section 6.10.          Registration Procedures.

(a)     In connection with each Registration Statement prepared pursuant to this Article VI pursuant to which Registrable Securities will be offered and sold, and in accordance with the intended method or methods of distribution of the Registrable Securities as described in such Registration Statement, the Company shall:

(vi)          use its reasonable best efforts to promptly notify Sponsor Stockholder and the managing underwriter or underwriters, if any, after becoming aware thereof, (A) when the Registration Statement or any related Prospectus or any amendment or supplement thereto has been filed, and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective, (B) of any request by the SEC or any U.S. state securities authority for amendments or supplements to the Registration Statement or the related Prospectus or for additional information, (C) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, (D) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose or (E) within the Effective Period of the happening

of any event or the existence of any fact which makes any statement in the Registration Statement or any post-effective amendment thereto, Prospectus or any amendment or supplement thereto, or any document incorporated therein by reference untrue in any material respect or which requires the making of any changes in the Registration Statement or post-effective amendment thereto or any Prospectus or amendment or supplement thereto so that they 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)       during the Effective Period, use its reasonable best efforts to obtain, as promptly as practicable, the withdrawal of any order enjoining or suspending the use or effectiveness of the Registration Statement or any post-effective amendment thereto or the lifting of any suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction at the earliest date reasonably practicable;

(viii)       use its reasonable best efforts to deliver promptly to Sponsor Stockholder and the managing underwriters, if any, copies of all correspondence between the SEC and the Company, its legal counsel or auditors and all memoranda relating to discussions with the SEC or its staff with respect to the Registration Statement (except to the extent such correspondence is currently available via EDGAR);

(xii)        in the case of a firm commitment Underwritten Offering, use its reasonable best efforts to, as promptly as reasonably practicable, enter into an underwriting agreement customary in form and substance (taking into account the Company’s prior underwriting agreements) for firm commitment underwritten secondary offerings of the nature contemplated by the applicable Registration Statement;

(xiii)       use its reasonable best efforts to, as promptly as reasonably practicable, obtain an opinion from the Company’s outside and internal legal counsel and a “comfort” letter (and bring-down “comfort” letter) from the Company’s independent public accountants (and, if necessary, any other independent certified public accountants of any Subsidiary of the Company, any accounting predecessor or successor to the Company (including, for the avoidance of doubt, the SpinCo Business (as defined in the Separation and Distribution Agreement)) or any business acquired by the Company for which financial statements and financial data is, or is required to be, included in the Registration Statement) in customary form and covering such matters as are customarily covered by such opinions, “comfort” letters and bring-down “comfort” letters in connection with an offering of the nature contemplated by the applicable Registration Statement;

(xiv)       use its reasonable best efforts to, as promptly as reasonably practicable, provide to legal counsel to Sponsor Stockholder and to the managing underwriters, if any, and no later than the time of filing of any document which is to be incorporated by reference into the Registration Statement or Prospectus (after the initial filing of such Registration Statement), copies of any such document;

(xv)        cause its officers to fully cooperate with the marketing of the Registrable Securities covered by the Registration Statement, including, at the recommendation or request of the underwriters, making themselves available to participate in presentations (including “road-shows”), “one-on-one,” and other customary marketing activities in such locations (domestic and foreign) as recommended by the underwriter(s);

(xvi)       take no direct or indirect action prohibited by Regulation M under the Exchange Act;

(xvii)      otherwise use its reasonable best efforts to comply with, and cause its officers to comply with, all applicable rules and regulations of the Financial Industry Regulatory Authority (“FINRA”) (including by collecting and delivering any FINRA questionnaires requested by counsel to Sponsor Stockholder), the SEC and NYSE (or any other applicable national securities exchange);

(xviii)     use its reasonable best efforts to comply with the requirements of Rule 144(c)(1) with respect to public information about the Company; and

(xix)       use its reasonable best efforts to take all other steps, at the written request of Sponsor Stockholder, as may be necessary to effect the registration and offer of the Registrable Securities as required hereby.

(b)          In the event that the Company would be required, pursuant to Section 6.10(a)(vi)(E), to notify Sponsor Stockholder or the managing underwriter or underwriters, if any, of the happening of any event specified therein, the Company shall, subject to Section 6.03(c), as promptly as practicable, prepare and furnish to Sponsor Stockholder and to each such underwriter a reasonable number of copies of a Prospectus supplemented or amended so that, as thereafter delivered to purchasers of Registrable Securities that have been Registered pursuant to this Agreement, such Prospectus shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.  Sponsor Stockholder agrees that, upon receipt of any notice from the Company pursuant to Section 6.10(a)(vi)(E), it shall, and shall use its reasonable best efforts to, cause any sales or placement agent or agents for the Registrable Securities and the underwriters, if any, to forthwith discontinue disposition of the Registrable Securities until such Person shall have received copies of such amended or supplemented Prospectus and, if so directed by the Company, to destroy all copies, other than permanent file copies, then in its possession of the Prospectus (prior to such amendment or supplement) covering such Registrable Securities as soon as practicable after Sponsor Stockholder’s receipt of such notice.

(c)          If requested by the managing underwriter for an Underwritten Offering (primary or secondary) of any equity securities of the Company, Sponsor Stockholder agrees not to effect any Transfer of any Registrable Securities, including any sale pursuant to Rule 144, and not to effect any Transfer of any other equity security of the Company (in each case, other than as part of such underwritten public offering) during the 10 days prior to, and during the 90-day period (or such longer period as Sponsor Stockholder agrees with the underwriter of such offering) beginning on, the consummation of any underwritten public offering covered by a Registration Statement referred to in Section 6.05 if Sponsor Stockholder is permitted to include Registrable Securities thereunder.

(d)          The Company hereby agrees that if it shall previously have received a request pursuant to Section 6.01 or Section 6.02 for Registration of Registrable Securities in an Underwritten Offering, and if such previous Registration shall not have been withdrawn or abandoned, the Company, if requested by the managing underwriter for such Underwritten Offering, shall not Transfer to a third party or third parties any Common Stock, any other equity security of the Company or any security convertible into or exchangeable for any equity security of the Company until the earlier of (i) 90 days after the effective date of such Registration Statement and (ii) such time as all of the Registrable Securities covered by such Registration Statement have been distributed;

provided, however, that notwithstanding the foregoing, the Company may Transfer Common Stock or such other securities (A) as part of such Underwritten Offering subject to Section 6.06, (B) pursuant to a Registration Statement on Form S-8 or Form S-4 under the Securities Act or any successor or similar form, (C) as part of a transaction under Rule 145 of the Securities Act, (D) in one or more private transactions that would not interfere with the method of distribution contemplated by such Registration Statement or (E) if such Transfer was publicly announced or agreed to in writing by the Company prior to the date of the receipt of such request pursuant to Section 6.01, but subject to Section 6.06 if applicable.

(e)     Sponsor Stockholder shall furnish to the Company in writing such information regarding Sponsor Stockholder and its intended method of distribution of the Registrable Securities as the Company may from time to time reasonably request in writing in order for the Company to comply with its obligations under all applicable securities and other laws and to ensure that the Prospectus relating to such Registrable Securities conforms to the applicable requirements of the Securities Act and the rules and regulations thereunder.  Sponsor Stockholder shall promptly notify the Company of any inaccuracy or change in information previously furnished by Sponsor Stockholder to the Company or of the occurrence of any event, in either case as a result of which any Prospectus relating to the Registrable Securities contains or would contain an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and promptly furnish to the Company any additional information required to correct and update any previously furnished information or required so that such Prospectus shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(f)      In the case of any Underwritten Offering of shares of Common Stock Registered under a Takedown Prospectus Supplement or a Demand Registration Statement, or in the case of a Registration under Section 6.05 if the Company has entered into an underwriting agreement in connection therewith, all shares of Common Stock to be included in such offering or Registration, as the case may be, shall be subject to the applicable underwriting agreement and no Person may participate in such offering or Registration unless such Person agrees to sell such Person’s securities on the basis provided therein and completes and executes all questionnaires, indemnities, underwriting agreements and other documents (other than powers of attorney) which must be executed in connection therewith, and provides such other information to the Company or the underwriter as may be reasonably requested to offer or Register such Person’s Common Stock.

Section 6.11.          No Inconsistent Agreements.  Without the prior written consent of Sponsor Stockholder, except for the Registration Rights Agreement entered into on the date hereof, by and between Jacobs and the Company, neither the Company nor any of its Subsidiaries shall enter into any agreement granting Registration or similar

rights to any Person that are prior in right, pari passu or inconsistent with the rights under this Agreement.

Section 6.12.          Registration Expenses.  In connection with any Registration and sale of any Registrable Securities by Sponsor Stockholder, the Company shall bear all reasonably incurred, out-of-pocket Registration and filing fees, printing costs and fees and expenses of its and each Sponsor Stockholder’s legal counsel and accountants and, to the extent not borne by the underwriters in accordance with the terms of the applicable underwriting agreement, any underwriters (excluding, for the avoidance of doubt, any underwriters’ discounts or fees), except as otherwise provided in Section 6.02 where a request is revoked at the request of Sponsor Stockholder.

Section 6.13.          Indemnification; Contribution.

(a)     To the fullest extent permitted by applicable law, the Company shall, and it hereby agrees to, indemnify and hold harmless Sponsor Stockholder, each underwriter and the equityholders, controlling persons, directors, officers and employees of each of the foregoing in any offering or sale of the Registrable Securities, including pursuant to Section 6.01, Section 6.02 or Section 6.05, against any losses, claims, damages or liabilities, actions or proceedings (whether commenced or threatened) in respect thereof and expenses (including actual and documented out-of-pocket fees of legal counsel reasonably incurred) (collectively, “Claims”) to which each such indemnified party may become subject, insofar as such Claims (including any amounts paid in settlement effected with the consent of the Company as provided herein), or actions or proceedings in respect thereof, arise out of, relate to, are in connection with, or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, or any preliminary or final Prospectus contained therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or arise out of, relate to, are in connection with, or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and the Company shall, and it hereby agrees to, reimburse periodically each such indemnified Person for any actual and documented out-of-pocket legal or other actual and documented out-of-pocket expenses reasonably incurred by it in connection with investigating or defending any such Claims; provided, however, that the Company shall not be liable to any such Person in any such case to the extent that any such Claims arise out of, relate to, are in connection with, or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, or preliminary or final Prospectus, or amendment or supplement thereto, in reliance upon written information furnished to the Company (x) by Sponsor Stockholder or any Representative of Sponsor Stockholder, expressly for use therein, it being understood and agreed that the only such information furnished by Sponsor Stockholder or any Representative of Sponsor Stockholder consists of the information described as such in Section 6.13(b) or (y) by or on behalf of any underwriter expressly for use therein.

(b)     To the fullest extent permitted by applicable law, Sponsor Stockholder shall, and hereby agrees to, (i) indemnify and hold harmless the Company, its directors, officers, employees and its other equityholders and each underwriter, its partners, officers, directors, employees and controlling Persons, if any, in any offering or sale of Registrable Securities by it against any Claims to which each such indemnified party may become subject, insofar as such Claims (including any amounts paid in settlement as provided herein), or actions or proceedings in respect thereof, arise out of, relate to, are in connection with, or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, or any preliminary or final Prospectus contained therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or arise out of, relate to, are in connection with, or are based upon 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, in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information regarding Sponsor Stockholder furnished to the Company by Sponsor Stockholder or any Representative of Sponsor Stockholder expressly for use therein, it being understood and agreed that the only such information furnished by Sponsor Stockholder or any Representative of Sponsor Stockholder consists of the number of shares of Common Stock owned by Sponsor Stockholder, the number of Registrable Securities proposed to be sold by Sponsor Stockholder, the name and address of Sponsor Stockholder and the method of distribution proposed by Sponsor Stockholder, and (ii) reimburse the Company for any actual and documented out-of-pocket legal or other out-of-pocket expenses reasonably incurred by the Company in connection with investigating or defending any such Claim; provided, however, that in no event shall any indemnity or reimbursement by Sponsor Stockholder under this Section 6.13(b) exceed an amount equal to the net proceeds received by Sponsor Stockholder in respect of the sale of Registrable Securities giving rise to such indemnification or reimbursement obligation.

(c)     Sponsor Stockholder and the Company agree that if, for any reason, the indemnification provisions contemplated by Section 6.13(a) or Section 6.13(b) are unavailable to or are insufficient to hold harmless an indemnified party in respect of any Claims referred to therein, then each Indemnifying Party (as defined below) shall contribute to the amount paid or payable by such indemnified party as a result of such Claims in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the indemnified party, on the other hand, with respect to the applicable offering of securities.  The relative fault of such Indemnifying Party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such Indemnifying Party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  If, however, the allocation in the first sentence of this Section 6.13(c) is not permitted by applicable law, then each Indemnifying Party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative faults, but also the relative benefits of the Indemnifying Party and

the indemnified party, as well as any other relevant equitable considerations.  The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6.13(c) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the preceding sentences of this Section 6.13(c).  The amount paid or payable by an indemnified party as a result of the Claims referred to above shall be deemed to include (subject to the limitations set forth in Section 6.14) any actual and documented out-of-pocket legal or other out-of-pocket fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action, proceeding or claim.  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 6.14.          Indemnification Procedures.

(a)     If an indemnified party shall desire to assert any claim for indemnification provided for under Section 6.13 in respect of, arising out of or involving a Claim against such indemnified party, such indemnified party shall notify the Company or Sponsor Stockholder, as the case may be (the “Indemnifying Party”), in writing of such Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”) promptly after receipt by such indemnified party of written notice of the Claim; provided, however, that failure to provide a Claim Notice shall not affect the indemnification obligations provided hereunder except to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure.  The indemnified party shall deliver to the Indemnifying Party, promptly after the indemnified party’s receipt thereof, copies of all notices and documents (including court papers) received by the indemnified party relating to the Claim; provided, however, that failure to provide any such copies shall not affect the indemnification obligations provided hereunder except to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure.

(b)     If a Claim is made against an indemnified party, the Indemnifying Party will be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with separate counsel selected by the Indemnifying Party and reasonably satisfactory to the indemnified party.  Should the Indemnifying Party so elect to assume the defense of a Claim, the Indemnifying Party will not be liable to the indemnified party for legal expenses subsequently incurred by the indemnified party in connection with the defense thereof, unless the Claim involves potential conflicts of interest or substantially different defenses for the indemnified party and the Indemnifying Party.  If the Indemnifying Party assumes such defense, the indemnified party shall have the right to participate in the defense thereof and to employ legal counsel, at its own expense (except as provided in the immediately preceding sentence), separate from the legal counsel employed by the Indemnifying Party.  The Indemnifying Party shall be liable for the actual and documented out-of-pocket fees and expenses of legal counsel

reasonably incurred by the indemnified party for any period during which the Indemnifying Party has not assumed the defense thereof and as otherwise contemplated by the two immediately preceding sentences.  If the Indemnifying Party chooses to defend any Claim, the other party shall cooperate in the defense or prosecution thereof.  Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such Claim, and use of reasonable efforts to make employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.  Whether or not the Indemnifying Party shall have assumed the defense of a Claim, the indemnified party shall not admit any liability with respect to, or settle, compromise or discharge, such Claim without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).  The Indemnifying Party may pay, settle or compromise a Claim without the written consent of the indemnified party, only if such settlement (i) includes an unconditional release of the indemnified party from all liability in respect of such Claim, (ii) does not subject the indemnified party to any injunctive relief or other equitable remedy, and (iii) does not include a statement or admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(c)     The indemnification provided for under this Article VI will remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party or any officer, director employee, equityholder or controlling Person of such indemnified party and will survive the registration and sale of any Registrable Securities by any Person entitled to any indemnification hereunder and the expiration or termination of this Agreement.

Section 7.01.          Term.  This Agreement will be effective as of the date hereof.  This Agreement (other than Article VI and Article VII, which shall survive the expiration or termination of this Agreement indefinitely) shall terminate automatically on the Fallaway Date; provided that Section 3.04 shall survive for a period of three years after the expiration or termination of this Agreement.

Section 7.02.          Stockholder Indemnification; Limitation of Liability.  The Company shall defend, indemnify and hold harmless each Sponsor Related Person from and against any Claims to which such Sponsor Related Person may become subject, insofar as such Claims (including any amounts paid in settlement effected with the consent of the Company as provided herein), or actions or proceedings in respect thereof, arise out of, relate to, are in connection with, or are based upon, and no Sponsor Related Person shall be personally liable to the Company or any other Sponsor Related Person for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with, (a) any Sponsor Related Person’s beneficial ownership of Common Stock or other equity securities of the Company or control or ability to influence the Company or any of its Subsidiaries (other than to the extent such Claims or actions or

proceedings (i) arise out of any breach of this Agreement or other contractual obligation by a Sponsor Related Person or the breach of any fiduciary or other similar duty or obligation of such Sponsor Related Person or (ii) are directly caused by such Person’s willful misconduct), or (b) the business, operations, properties, assets or other rights or liabilities of the Company or any of its Subsidiaries.  If a Sponsor Related Person shall desire to assert any claim for indemnification provided for under this Section 7.02 in respect of, arising out of or involving a Claim against such Sponsor Related Person, the indemnification procedures contained in Section 6.14 shall govern, mutatis mutandis.

Section 7.03.          Indemnification Priority.  The Company hereby acknowledges that the Sponsor Related Persons may have certain rights to indemnification, advancement of expenses or insurance provided by one or more Sponsor Related Persons (collectively, the “Sponsor Stockholder Indemnitors”).  The Company hereby (a) agrees that the Company and any Subsidiary of the Company that provides an indemnity shall be the indemnitor of first resort (i.e., its or their obligations to a Sponsor Related Person shall be primary and any obligation of any Sponsor Stockholder Indemnitor to advance expenses or to provide indemnification for the same expenses or liabilities incurred by a Sponsor Related Person shall be secondary), (b) agrees that it shall be required to advance the full amount of expenses incurred by a Sponsor Related Person and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement or any other agreement between the Company and a Sponsor Related Person, without regard to any rights a Sponsor Related Person may have against any Sponsor Stockholder Indemnitor or their insurers, and (c) irrevocably waives, relinquishes and releases the Sponsor Stockholder Indemnitors from any and all claims against the Sponsor Stockholder Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof.  The Company further agrees that no advancement or payment by the Sponsor Stockholder Indemnitors on behalf of a Sponsor Related Person with respect to any claim for which such Sponsor Related Person has sought indemnification from the Company, as the case may be, shall affect the foregoing and the Sponsor Stockholder Indemnitors shall have a right of contribution or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Sponsor Related Person against the Company.

Section 7.04.          Amendments and Waivers.  Except as otherwise provided herein, the provisions of this Agreement may be amended or waived only upon the prior written consent of the Company and Sponsor Stockholder.  No failure or delay by any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.  The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable law.

Section 7.05.          Successors and Assigns.  The rights and obligations hereunder shall not be assignable by any party hereto without the prior written consent of the other party hereto; provided that, subject to the execution of a joinder agreement substantially in the form of Exhibit A, Sponsor Stockholder may assign its rights and

obligations hereunder to any Sponsor Transferee without the prior written consent of the Company; provided the Sponsor Stockholder shall provide prior written notice to the Company of such Transfer and provided, further, that no such assignment shall release such assigning party from any liability or obligation under this Agreement.  Any attempted assignment of rights or obligations in violation of this Section 7.05 shall be null and void ab initio.  For the avoidance of doubt, any such Sponsor Transferee shall be subject to the restrictions in this Section 7.05.  In the event of any partial assignment of the rights and obligations available to Sponsor Stockholder in this Agreement, the rights available to Sponsor Stockholder in Article III shall be held jointly by the entities constituting “Sponsor Stockholder” in the aggregate and in no event shall be construed as separate or multiple rights of each entity constituting Sponsor Stockholder.  In the event that multiple entities constitute Sponsor Stockholder, the Company shall not be liable for any losses, costs or expenses arising directly or indirectly from the Company’s good faith reliance upon and compliance with instructions from any entity constituting part of the group that constitutes Sponsor Stockholder, including in the event that such instructions conflict with or are inconsistent with any separate written instructions.

Section 7.06.          Severability.  Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or the effectiveness or validity of any provision in any other jurisdiction, and this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein, unless the severance of such provision could be in opposition to the parties’ intent with respect to such provision or the economic or legal substance of the transactions contemplated hereby would be affected in any manner materially adverse to any party hereto, in which case the parties will negotiate revisions to this Agreement to preserve as nearly as possible or nearly as practicable the economic or legal substance of such invalid, illegal or unenforceable provision.

Section 7.07.          Counterparts; Electronic Signatures.  This Agreement may be executed in any number of separate counterparts each of which when so executed shall be deemed to be an original and all of which together shall constitute one and the same agreement.  Counterpart signature pages to this Agreement may be delivered by facsimile or electronic delivery (i.e., by email of a PDF signature page) and each such counterpart signature page will constitute an original for all purposes.  The parties hereto hereby agree that this Agreement may be executed by way of electronic signatures and that the electronic signature has the same binding effect as a physical signature.  For the avoidance of doubt, the parties hereto further agree that this Agreement, or any part thereof, shall not be denied legal effect, validity or enforceability solely on the ground that it is in the form of an electronic record.

Section 7.08.          Entire Agreement.  This Agreement (including the documents and the instruments referred to in this Agreement) and the other Transaction Documents, as applicable, constitute the entire agreement among the parties hereto or to

which they are subject and supersede all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter of the transactions contemplated hereby and thereby.

Section 7.09.          Governing Law.  This Agreement and all claims arising out of or based upon this Agreement or relating to the subject matter hereof shall be governed by and construed in accordance with the domestic substantive laws of the State of Delaware without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction.

Section 7.10.          Consent to Jurisdiction.  Each party to this Agreement, by its execution hereof, (a) hereby irrevocably submits to the exclusive jurisdiction of the Delaware Court of Chancery (or, solely if the Delaware Court of Chancery declines jurisdiction, the Complex Commercial Litigation Division of the Delaware Superior Court, New Castle County, or, solely if such court declines jurisdiction, the United States District Court for the District of Delaware) for the purpose of any action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation arising out of or based upon this Agreement or relating to the subject matter hereof, (b) hereby waives to the extent not prohibited by applicable law, and agrees not to assert, and agrees not to allow any of its Subsidiaries to assert, by way of motion, as a defense or otherwise, in any such action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that any such proceeding brought in one of the above-named courts is improper, or that this Agreement or the subject matter hereof or thereof may not be enforced in or by such above-named courts, and (c) hereby agrees not to commence or maintain any action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation arising out of or based upon this Agreement or relating to the subject matter hereof other than before one of the above-named courts nor to make any motion or take any other action seeking or intending to cause the transfer or removal of any such action, claim, cause of action or suit (in contract, tort or otherwise), inquiry, proceeding or investigation to any court other than one of the above-named courts whether on the grounds of inconvenient forum or otherwise.  Notwithstanding the foregoing, to the extent that any party hereto is or becomes a party in any litigation in connection with which it may assert indemnification rights set forth in this Agreement, the court in which such litigation is being heard shall be deemed to be included in clause (a) above.  Notwithstanding the foregoing, any party to this Agreement may commence and maintain an action to enforce a judgment of any of the above-named courts in any court of competent jurisdiction.  Each party hereto hereby consents to service of process in any such proceeding in any manner permitted by Delaware law, and agrees that service of process by registered or certified mail, return receipt requested, at its address specified pursuant to Section 7.14 is reasonably calculated to give actual notice.

Section 7.11.          WAIVER OF JURY TRIAL.  TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH PARTY HERETO HEREBY WAIVES, AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY

RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE OR ACTION, CLAIM, CAUSE OF ACTION OR SUIT (IN CONTRACT, TORT OR OTHERWISE), INQUIRY, PROCEEDING OR INVESTIGATION ARISING OUT OF OR BASED UPON THIS AGREEMENT OR THE SUBJECT MATTER HEREOF OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF ANY STOCKHOLDER IN CONNECTION WITH ANY OF THE ABOVE, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING AND WHETHER IN CONTRACT, TORT OR OTHERWISE.  EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH OF THE PARTIES HERETO ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE OTHER PARTY HERETO THAT THIS SECTION 7.11 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH IT IS RELYING AND WILL RELY IN ENTERING INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY.  ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 7.11 WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.

Section 7.12.          Specific Performance.  The parties hereto agree that irreparable damage may occur if any provision of this Agreement is not performed in accordance with the terms hereof and that the parties shall be entitled to seek an injunction or injunctions or other equitable relief to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any court set forth in Section 7.10, in addition to any other remedy to which they are entitled at law or in equity.

Section 7.13.          Third-Party Beneficiaries.  Except as set forth in Section 5.05 and except for any Person expressly entitled to indemnification rights under this Agreement, nothing in this Agreement shall confer any rights upon any Person other than (a) the parties hereto and (b) each such party’s respective heirs, successors and permitted assigns, all of whom shall be third-party beneficiaries of this Agreement.

Section 7.14.          Notices.  All notices and other communications in connection with this Agreement shall be in writing and shall be deemed given if delivered personally, sent via e-mail (so long as the sender of such email does not receive an automatic reply from the recipient’s email server indicating that the recipient did not receive such email), mailed by registered or certified mail (return receipt requested) or delivered by an express courier (with confirmation) to the parties at the following addresses (or at such other address for a party as shall be specified by like notice):
