The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion.

-8-

(d) Legends. The Holder acknowledges that, to the extent applicable, each certificate evidencing Exercise Shares issued upon exercise of this Option shall be endorsed with the legend substantially in the form set forth below, as well as any additional legend imposed or required by applicable state securities laws:

THE SECURITIES REPRESENTED BY THIS INSTRUMENT OR CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR SECURITIES LAWS OF ANY STATE AND MAY NOT BE OFFERED, SOLD, ASSIGNED, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE ACT OR SUCH LAWS AND, IF REQUESTED BY HC2 HOLDINGS, INC., OR ANY SUCCESSOR THERETO (THE “COMPANY”), UPON DELIVERY OF AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT THE PROPOSED TRANSFER IS EXEMPT FROM THE ACT OR SUCH LAWS.

9. Adjustment of Exercise Price and Number of Exercise Shares. The Exercise Price of this Option and the number of Exercise Shares issuable upon the exercise of this Option shall be adjusted from time to time as set forth in this Section 9, and which adjustment may be in the form of the issuance of a new option, which new option shall be subject to substantially the same terms as this Option, but with the modifications provided for in this Section 9.

(a) Corporate Transactions. In case (i) the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, (ii) the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, or combined into a smaller number of shares of Common Stock, (iii) the Company shall, by dividend or otherwise, distribute to all holders of Common Stock shares of any class of Capital Stock of the Company, debt securities, assets or other property of the Company, (iv) the Company shall make an extraordinary cash dividend to all holders of Common Stock or (v) the Company shall engage in any other transaction that would constitute a corporate transaction within the meaning of Section 424 of the Internal Revenue Code of 1986, as amended, or any successor statute thereto (“Code Section 424”), the number of shares of Common Stock to be received by the Holder and the Exercise Price payable upon exercise of this Option shall be appropriately adjusted in a manner that would satisfy the requirements of Code Section 424 (without regard to the requirement that an eligible corporation be the employer of the optionee) if the Option were a statutory stock option.

(b) Fundamental Change Transaction. If, at any time while any portion of this Option is outstanding there occurs a Fundamental Change Transaction, then (i) as of immediately prior to the occurrence of such Fundamental Change Transaction, this Option shall be deemed fully vested, and (ii) the Holder, from and after the occurrence of such Fundamental Change Transaction, shall have the right upon exercise of all or any portion of this Option (and payment of the applicable Exercise Price) to receive (but only out of legally

-9-

available funds, to the extent required by applicable law) the kind and amount of stock, other securities, cash and/or assets (the “Alternate Consideration”) that the Holder would have received if this Option (or portion thereof being exercised) had been exercised pursuant to the terms hereof immediately prior to such Fundamental Change Transaction (assuming for this purpose that the Holder did not exercise any applicable rights of election, if any, as to the kind or amount of stock, securities, cash, assets or other property receivable upon such Fundamental Change Transaction). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Change Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration, but in all events in accordance with the requirements of Code Section 424. Any successor to the Company or surviving Person in such Fundamental Change Transaction shall issue to the Holder a new option substantially in the form of this Option and consistent with the foregoing provisions and evidencing the Holder’s right to purchase the Alternate Consideration for the aggregate Exercise Price upon exercise thereof and, upon such issuance, this Option shall be automatically cancelled and shall cease to be of further force or effect. The terms of any agreement pursuant to which a Fundamental Change Transaction is effected shall include terms requiring any such successor or surviving Person to comply with the foregoing provisions.

(c) Calculations. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company. No adjustment need be made for:

(i) any Excluded Issuances;

(ii) a change in the par value of the Common Stock; or

(iii) any event for which an adjustment has already been provided under any subsection of this Section 9; provided, however, that if any event occurs that would result in an adjustment under more than one subsection of this Section 9, the subsection that results in the most favorable adjustment to the Holder shall control.

To the extent this Option becomes exercisable into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. Any adjustments to the number of Exercise Shares hereunder shall be apportioned among the three vesting tranches of the Option as nearly equal as possible.

(d) Form of Option After Adjustment. Except as otherwise provided in Section 9(b), the form of this Option need not be changed because of any adjustments in the Exercise Price or the number of Exercise Shares issuable upon exercise of this Option, and Options theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in this Option, as initially issued.

-10-

10. No Fractional Shares. No fractional shares of Common Stock shall be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall, at its sole option, (a) round up such fraction to the nearest whole number of shares of Common Stock or (b) make a cash payment therefor based on the Fair Market Value thereof.

11. Notices to Holder. Upon any adjustment of the number of Exercise Shares issuable upon exercise of this Option or the Exercise Price of this Option, including any adjustment pursuant to Section 9, the Company, within twenty (20) calendar days thereafter, shall prepare and deliver, or cause to be prepared and delivered, to the Holder a certificate signed by an officer setting forth the event giving rise to such adjustment, such Exercise Price and the number of Exercise Shares (as divided into each vesting tranche of the Option) after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such adjustment was made, which certificate shall be conclusive evidence of the correctness of the matters set forth therein. Where appropriate, such notice may be given in advance and included as a part of the notice required to be mailed under the other provisions of this Section 11. In the event of:

(a) a Rights Shares Issuance; or

(b) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of Capital Stock of any class or any other securities or property, or to receive any other right; or

(c) any Fundamental Change Transaction;

then, and in each such event, the Company shall cause written notice to be provided to the Holder of, respectively, (i) the date on which any such Rights Share Issuance is to occur and the number of Rights the applicable Rights holder(s) intends to exercise, convert or exchange and the total number of shares issuable upon the exercise of the related Rights, (ii) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, and (iii) the date on which any such Fundamental Change Transaction is anticipated to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or other securities) shall be entitled to exchange their shares of Common Stock (or other securities) for securities or other property deliverable on such Fundamental Change Transaction. Such notice shall be delivered by the Company as set forth above as soon as reasonably practicable prior to the date specified in such notice on which any such action is to be taken; provided, however, that in no event shall the Company be required to deliver such notice (x) more than ten (10) Business Days prior to such specified date or (y) prior to the time the Company publicly discloses or is required by law (if required by law) to publicly disclose such event. Failure to give such notice shall not affect the validity of any action taken in connection therewith.

12. No Stockholder Rights. Prior to exercise of this Option, the Holder shall not be entitled to any rights of a stockholder with respect to the Exercise Shares, including (without limitation) the right to vote such Exercise Shares, receive dividends or other

-11-

distributions thereon, exercise preemptive rights or be notified of stockholder meetings, and, except as otherwise provided in this Option, such Holder shall not be entitled to any stockholder notice or other communication concerning the business or affairs of the Company.

13. Transfer of Vested Portions of Option. Subject to compliance with applicable federal and state securities laws and any other contractual restrictions between the Company and the Holder contained herein, vested portions of this Option and all rights hereunder with respect thereto are transferable, in whole or in part, by the Holder upon prior written consent of the Company, not to be unreasonably withheld, conditioned or delayed, and upon receipt of an assignment agreement in form and substance satisfactory to the Company, pursuant to which the transferee will agree to be bound by the terms and conditions of this Option. Any such transfer shall be recorded on the books of the Company upon the surrender of this Option, properly endorsed, to the Company at its principal offices, and the payment to the Company of all transfer taxes and other governmental charges imposed on such transfer. In the event of a partial transfer, the Company shall issue to the new holders one or more appropriate new options.

14. Governing Law. This Option shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.

15. Submission to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Option or the transactions contemplated hereby may be instituted in the federal courts of the United States of America or the courts of the State of New York in each case located in the city of New York, and each party irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of process, summons, notice or other document by certified or registered mail to such party’s address set forth herein shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or any proceeding in such courts and irrevocably waive and agree not to plead or claim in any such court that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

16. Waiver of Jury Trial.

Any term or provision of this Option which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Option in any other jurisdiction. If any provision of this Option is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

22. Issue Tax. The issuance of certificates for Exercise Shares upon the exercise of this Option shall be made without charge to the Holder of this Option for any issue tax in respect thereof; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the then holder of this Option being exercised.

23. Third-Party Beneficiaries. Nothing in this Option shall be construed to give to any Person other than the Company and the Holder any legal or equitable right, remedy or claim under this Option, and this Option shall be for the sole and exclusive benefit of the Company and the Holder.

24. Counterparts. This Option may be executed in any number of counterparts (including by facsimile or portable document format (PDF) signatures) and each of such counterparts shall for all purposes be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.

25. Headings. The headings of sections of this Option have been inserted for convenience of reference only, are not to be considered a part hereof and in no way modify or restrict any of the terms or provisions hereof.

26. Remedies. Each party stipulates that the remedies at law of the other party in the event of any default or threatened default in the performance of or compliance with any of the terms of this Option are not and will not be adequate, and that such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any terms hereof or otherwise. The remedies herein provided are in addition to and not exclusive of any other remedies provided at law or in equity.
