Ladies and Gentlemen:

Iridium Communications Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the several Underwriters named in Schedule I hereto (the “Underwriters”), an aggregate of 500,000 shares 6.75% Cumulative Perpetual Convertible Preferred Stock (the “Shares”). The Shares initially shall be convertible into 33.4560 shares of common stock, $0.001 par value, of the Company (the “Common Stock”), as described in the Prospectus, defined below. The shares of Common Stock into which the Shares may be converted are referred to herein as the “Conversion Shares.” The Shares will be established by the filing with the Secretary of State of the State of Delaware of a statement of resolution of the Board of Directors of the Company establishing and designating the 6.75% Cumulative Perpetual Convertible Preferred Stock, Series B (the “Certificate of Designations”). The Shares and the Conversion Shares hereinafter are referred to collectively as the “Securities.” Deutsche Bank Securities Inc. and Xxxxxxx Xxxxx & Associates, Inc. are acting as the representatives of the several Underwriters and in such capacity are referred to in this Agreement as the “Representatives.”

The Company wishes to confirm as follows its agreement with you and the other several Underwriters, on whose behalf you are acting, in connection with the several purchases of the Shares from the Company.

1. Registration Statement and Prospectus. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission

thereunder (collectively, the “Act”), a shelf registration statement on Form S-3 (File No. 333-194869), including a form of base prospectus included therein (the “Base Prospectus”), relating to the Shares. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, at the time when it became effective, including all documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B or Rule 430C under the Act, is referred to in this Agreement as the “Registration Statement.” If the Company files another registration statement with the Commission to register a portion of the Shares pursuant to Rule 462(b) under the Act (the “Rule 462 Registration Statement”), then any reference to “Registration Statement” herein shall be deemed to include the registration statement on Form S-3 (File No. 333-194869) and the Rule 462 Registration Statement, as each such registration statement may be amended pursuant to the Act. The preliminary prospectus supplement dated May 5, 2014 describing the Securities and the offering thereof, together with the Base Prospectus, is called the “Preliminary Prospectus,” and the Preliminary Prospectus and any other preliminary prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof and is used prior to the filing of the Prospectus (as defined below), together with the Base Prospectus, is called a “preliminary prospectus.” As used herein, the term “Prospectus” shall mean the final prospectus supplement to the Base Prospectus that describes the Securities and the offering of the Shares (the “Final Prospectus Supplement”), together with the Base Prospectus, in the form first used by the Underwriters to confirm sales of the Shares or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Act. For purposes of this Agreement, “free writing prospectus” has the meaning ascribed to it in Rule 405 under the Act, and “Issuer Free Writing Prospectus” shall mean each free writing prospectus prepared by or on behalf of the Company or used or referred to by the Company in connection with the offering of the Shares. “Time of Sale Information” shall mean the Preliminary Prospectus together with the free writing prospectuses, if any, each identified in Schedule II hereto, the information identified in Schedule III hereto and each “road show” (as defined in Rule 433 under the Act), if any, related to the offering of the Shares contemplated hereby that is a “written communication” (as defined in Rule 405 under the Act) (each such road show, a “Road Show”). All references in this Agreement to the Registration Statement, the Rule 462 Registration Statement, a Preliminary Prospectus, the Prospectus or the Time of Sale Information, or any amendments or supplements to any of the foregoing, shall be deemed to refer to and include any documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act, as of the date of the Registration Statement, such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to any amendment or supplement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that, upon filing, are incorporated by reference therein, as required by paragraph (b) of Item 12 of Form S-3, and shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”).

previously consented to by the Representatives is set forth substantially in the form and substance as attached hereto on Schedule II.

(k) The issued interests of each of the Company’s subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are owned directly or indirectly by the Company free and clear of any security interests, liens, encumbrances or claims, except for such interests, liens, encumbrances or claims that have been disclosed in the Time of Sale Information and the Prospectus or would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. Other than those listed on Exhibit A hereto, the Company has no “significant subsidiaries” within the meaning of Rule 1-02(w) of Regulation S-X under the Exchange Act, and any subsidiaries of the Company not listed on Exhibit A hereto, considered in the aggregate as a single subsidiary, would not constitute a significant subsidiary.

(l) The Certificate of Designations, the proposed form of which has been furnished to you, will have been duly filed with the Secretary of State of Delaware on or before the time and date for payment and delivery of the Shares.

(m) The issuance of the Shares to be sold to the Underwriters by the Company hereunder has been duly and validly authorized by the Company and, when issued, delivered and paid for in accordance with the terms of this Agreement, will have been duly and validly issued and will be fully paid and non-assessable, free and clear of any preemptive or similar rights and will conform in all material respects to the description thereof contained in the Registration Statement, the Time of Sale Information and the Prospectus and such description conforms in all material respects to the rights set forth in the instruments defining the same.

(n) The authorized capital stock of the Company conforms as to legal matters to the description thereof contained in the Registration Statement, the Time of Sale Information and the Prospectus (or any amendment or supplement thereto).

None of the outstanding shares of Common Stock was issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase or acquire any securities of the Company or any of its subsidiaries, except any such rights as have been waived in writing.

(s) None of the issuance and sale of the Shares by the Company, the execution, delivery or performance of this Agreement by the Company nor the consummation by the Company of the transactions contemplated hereby (i) requires any consent, approval, authorization or other order of or registration or filing with, any court, regulatory body, administrative agency or other governmental body, agency or official (except such as may be required for the registration of the Shares under the Act, the listing of the Shares for trading on the NASDAQ, the registration of the Common Stock under the Exchange Act and compliance with the securities or Blue Sky laws of various jurisdictions, all of which will be, or have been, effected in accordance with this Agreement and except for FINRA’s clearance of the underwriting terms of the offering contemplated hereby as required under FINRA’s Rules of Fair

As used herein, a “Debt Repayment Triggering Event” means any event or condition that gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries.

(t) Except as described in the Registration Statement, the Time of Sale Information and the Prospectus, neither the Company nor any of its subsidiaries has outstanding, and at the Closing Date, will have outstanding, any options to purchase, or any warrants to subscribe for, or any securities or obligations convertible into, or any contracts or commitments to issue or sell, any capital stock or any warrants or convertible securities or obligations.

(oo) The Company has established, maintains and evaluates “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act), which (i) are designed to ensure that material information relating to the Company and its subsidiaries is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared, (ii) have been evaluated for effectiveness as of the end of the last fiscal period covered by the Time of Sale Information and the Prospectus; and (iii) such disclosure controls and procedures are effective to perform the functions for which they were established. There are no significant deficiencies or material weaknesses in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize, or report financial data to management and the Board of Directors of the Company. The Company is not aware of any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

This indemnification shall be in addition to any liability that the Company may otherwise have.

If any action or claim shall be brought against any Underwriter or any person controlling any Underwriter in respect of which indemnity may be sought against the Company, such Underwriter or such controlling person shall promptly notify in writing the party(s) against whom indemnification is being sought (the “indemnifying party” or “indemnifying parties”), and such indemnifying party(s) shall assume the defense thereof, including the employment of counsel reasonably acceptable to such Underwriter or such controlling person and the payment of all reasonable fees of and expenses incurred by such counsel. Such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person, unless (i) the indemnifying party(s) has (have) agreed in writing to pay such fees and expenses, (ii) the indemnifying party(s) has (have) failed to assume the defense and employ counsel reasonably acceptable to the Underwriter or such controlling person within a reasonable period of time or (iii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such controlling person and the indemnifying party(s), and such Underwriter or such controlling person shall have been advised by its counsel that one or more legal defenses may be available to the Underwriter that may not be available to the Company, or that representation of such indemnified party and any indemnifying party(s) by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the indemnifying party(s) shall not have the right to assume the defense of such action on behalf of such Underwriter or such controlling person (but the Company shall not be liable for the fees and expenses of more than one counsel for the Underwriters and such controlling persons)). The indemnifying party(s) shall not be liable for any settlement of any such action effected without its (their several) written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, the indemnifying party(s) agree(s) to indemnify and hold harmless any Underwriter and any such controlling person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment, but in the case of a judgment only to the extent stated in the first paragraph of this Section 8.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors, officers, employees and agents of the Company and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing several indemnity from the Company to each Underwriter, but only with respect to the Specified Information furnished by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus or any Preliminary Prospectus, or any amendment or supplement thereto. If any action or claim shall be brought or asserted against the Company, any of its directors, officers, employees and agents or any such controlling person based on the Registration Statement, the Prospectus, the Time of Sale Information or any Preliminary Prospectus, or any amendment or supplement thereto, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph, such Underwriter shall have the rights and duties given to the Company by the immediately preceding paragraph (except that if the Company shall have assumed the defense thereof such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel shall be at such Underwriter’s expense), and the Company, its directors, officers, employees and agents and any such controlling persons, shall have the rights and duties given to the Underwriters by the immediately preceding paragraph.

In any event, any indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any proceeding or threatened claim, action, suit or proceeding in respect of which the indemnification may be sought hereunder (whether or not the indemnified party or any person who controls the indemnified party within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of all indemnified parties and such controlling persons from all liability arising out of such claim, action, suit or proceeding.

If the indemnification provided for in this Section 8 is unavailable or insufficient for any reason whatsoever to an indemnified party in respect of any Damages referred to herein, then an 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 Damages (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand, and the Underwriters on the other hand, from the offering and sale of the Shares 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 and several fault of the Company on the one hand, and the Underwriters on the other hand, in connection with the statements or omissions that resulted in such Damages as well as any other relevant equitable considerations. The relative and several benefits received by the Company on the one hand, and the Underwriters on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand, and the Underwriters on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to

information supplied by the Company on the one hand, or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 was determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the Damages 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 Section 8, no Underwriter shall be required to contribute any amount in excess of the amount of the underwriting commissions received by such underwriter in connection with the Shares underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to the respective numbers of Shares set forth opposite their names in Schedule I hereto (or such numbers of Shares increased as set forth in Section 10 hereof) and not joint.

Any Damages for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as Damages are incurred after receipt of reasonably itemized invoices therefor. The indemnity, contribution and reimbursement agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, its directors, officers, employees and agents or any person controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to the Company, its directors, officers, employees and agents or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

12. Termination of Agreement. (a) This Agreement shall be subject to termination in your absolute discretion, without liability on the part of any Underwriter to the Company by notice to the Company in the event that (x) the Company has failed, refused or been unable to satisfy all conditions and obligations on its part to be performed or satisfied hereunder on or prior to the Closing Date or (y) if prior to the Closing Date: (i) any domestic or international event or act or occurrence has materially disrupted, or in your reasonable opinion will in the immediate future materially disrupt, the market for the Company’s securities or securities in general, (ii) trading in any of the Company’s securities shall have been suspended or materially limited by the Commission or by the NASDAQ, or trading in securities generally on the New York Stock Exchange (“NYSE”), the NYSE MKT, or the NASDAQ shall have been suspended or made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NYSE, the NYSE MKT, or the NASDAQ or by order of the Commission or other regulatory body or governmental authority having jurisdiction, (iii) a banking moratorium has been declared by any state or federal authority or if any material disruption in commercial banking or securities settlement or clearance services shall have occurred, or (iv) (A) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States, or (B) there shall have been any other calamity or crisis or any change in political, financial or economic conditions if the effect of any such event in (A) or (B), in your judgment, makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Shares on the terms and in the manner contemplated by the Time of Sale Information and the Prospectus.

(b) Subject to paragraph (c) below, termination of this Agreement pursuant to this Section 12 shall be without liability of any party to any other party except as provided in Section 16 hereof.

(c) If this Agreement shall be terminated, or if the sale of the Shares provided for herein is not consummated, because any condition to the obligations of the Underwriters set

forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Underwriters, reimburse the Underwriters for all out-of-pocket expenses (including the reasonable fees and the expenses of their counsel), incurred by the Underwriters in connection herewith.

13. Information Furnished by the Underwriters. The Company acknowledges that the ninth, tenth, eleventh, twelfth and nineteenth paragraphs under the caption “Underwriting” in any Preliminary Prospectus (the “Specified Information”) constitute the only information furnished by or on behalf of the Underwriters through you or on your behalf as such information is referred to in Sections 6 and 8 hereof.

16. Survival. The respective representations, warranties, agreements, covenants, and indemnities of the Company, and the Underwriters set forth in this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Company, any of its officers or directors, the Underwriters or any controlling person referred to in Section 8 hereof and (ii) delivery of and payment for the Shares, and shall, subject to Section 17 hereof, be binding upon and shall, subject to Section 17 hereof, inure to the benefit of, any successors, permitted assigns, heirs, legal representatives of the Company, the Underwriters and indemnified parties referred to in Section 8 hereof. The respective agreements, covenants, and indemnities set forth in Sections 7, 8, 12 and 16 hereof shall remain in full force and effect, regardless of any termination of this Agreement.

17. Successors. This Agreement shall inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors, permitted assigns and legal

representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained; this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of no other person except that (i) the indemnities of the Company contained in Section 8 hereof shall also be for the benefit of any person or persons who control the Underwriters within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the Underwriters contained in Section 8 hereof shall also be for the benefit of the directors of the Company, its officers, employees and agents and any person or persons who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act. No purchaser of Shares from the Underwriters will be deemed a successor or an assign because of such purchase. Prior to the closing on the Closing Date, no party may assign this Agreement or any of its rights hereunder without the prior written consent of the other party or parties.

18. No Fiduciary Duty. Notwithstanding any pre-existing relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by any of the Underwriters, the Company acknowledges and agrees that (i) nothing herein shall create a fiduciary or agency relationship between the Company, on the one hand, and the Underwriters, on the other hand; (ii) the Underwriters have been retained solely to act as underwriters and are not acting as advisors, expert or otherwise, to either the Company in connection with this offering, the sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares; (iii) the relationship between the Company, on the one hand, and the Underwriters, on the other hand, is entirely and solely commercial, and the price of the Shares was established by the Company and the Underwriters based on discussions and arms’ length negotiations and the Company understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (iv) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (v) notwithstanding anything in this Agreement to the contrary, the Company acknowledges that the Underwriters may have financial interests in the success of the Offering that are not limited to the difference between the price to the public and the purchase price paid to the Company for the shares and such interests may differ from the interests of the Company, and the Underwriters have no obligation to disclose, or account to the Company for any benefit they may derive from such additional financial interests. The Company hereby waives and releases, to the fullest extent permitted by the applicable law, any claims it may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company or any of its shareholders, managers, employees or creditors.

19. Research Analyst Independence. The Company acknowledge that (a) the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies and (b) the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company, the

value of the Common Stock and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by the Underwriters’ independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by any Underwriter’s investment banking division. The Company acknowledges that each of the Underwriters is a full service securities firm and as such, from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that are the subject of the transactions contemplated by this Agreement.

20. Entire Agreement. This Agreement constitutes the entire agreement among the parties hereto and supersedes all prior agreements, representations, warranties, understandings and arrangements, oral or written, among the parties hereto with respect to the subject matter hereof.

Funding Plan:		We estimate the aggregate costs associated with the design, build and launch of Iridium NEXT and related infrastructure upgrades through 2017 to be approximately

III-1


		$3 billion. Our funding plan for these costs includes the substantial majority of the funds available under our $1.8 billion loan facility, or the Credit Facility, together with cash and marketable securities on hand, internally generated cash flows, including potential cash flows from hosted payloads and Iridium PRIME^SM, and the proceeds from these offerings. We currently use the credit facility to pay 85% of each invoice we receive from Thales under their contract for the development and construction of our Iridium NEXT satellites, with the remaining 15% funded from cash on hand. We also utilize the Credit Facility to fund a portion of the interest under the Credit Facility and COFACE insurance premiums. Once the Credit Facility is fully drawn, we expect to pay 100% of each invoice we receive from Thales and all interest on the Credit Facility from cash and marketable securities on hand, internally generated cash flows, including potential cash flows from hosted payloads and Iridium PRIME, and with the proceeds from these offerings.

Capitalized terms used but not defined herein have the respective meanings assigned to such terms in the Underwriting Agreements.

B-1

The undersigned recognizes that it is in the best financial interests of the undersigned, as an officer or director, or an owner of stock, options, warrants or other securities of the Company (the “Company Securities”), that the Company complete the proposed Offerings.

The undersigned further recognizes that the Company Securities held by the undersigned are, or may be, subject to certain restrictions on transferability, including those imposed by United States federal securities laws. Notwithstanding these restrictions, the undersigned has agreed to enter into this letter agreement to further assure the Underwriters that the Company Securities of the undersigned, now held or hereafter acquired, will not enter the public market at a time that might impair the underwriting effort.

Therefore, as an inducement to the Underwriters to execute the Underwriting Agreements, the undersigned hereby acknowledges and agrees that the undersigned will not (i) offer for sale, sell, pledge or otherwise dispose of or enter into any transaction or device that is designed to, or could be expected to, result in the disposition of (collectively, a “Disposition”) any Company Securities, or securities convertible into or exchangeable for Company Securities or sell or grant options, rights or warrants with respect to any shares of Company Securities or securities convertible into or exchangeable for Company Securities, any Company Securities held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned (collectively, the “Lock-Up Shares”), pursuant to the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended, for a period commencing on the date hereof and ending 90 days after the date of the Underwriting Agreements, inclusive (the “Lock-Up Period”), without the prior written consent of the Representatives, (ii) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of Lock-Up Shares, whether any such transaction described in clause (i) above or this clause (ii) is to be settled by delivery of Company Securities, in cash or otherwise, or (iii) publicly disclose the intention to do any of the foregoing, in each case without the prior written consent of Xxxxxxx Xxxxx & Associates and Deutsche Bank Securities Inc. on behalf of the Underwriters and the underwriters of the Series B Preferred Stock, during the Lock-Up Period; notwithstanding the foregoing, if (x) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or announces material news or a material event relating to the Company occurs or (y) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed in the preceding paragraph shall continue to apply until the expiration of the 18-day period beginning on the date of issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless Xxxxxxx Xxxxx & Associates and Deutsche Bank Securities Inc., on behalf of the Underwriters and the underwriters of the Series B Preferred Stock, waive such extension in writing. The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging, collar (whether or not for any consideration) or other transaction that is designed to or reasonably expected to lead or result in a Disposition of Lock-Up Shares during the Lock-Up Period, even if such Lock-Up Shares would be disposed of by someone other than such holder. Such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call

B-2

option or reversal or cancellation thereof) with respect to any Lock-Up Shares or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from Lock-Up Shares.

Notwithstanding the agreement not to make any Disposition during the Lock-Up Period, and subject to the conditions below, you have agreed that the foregoing restrictions shall not apply to Disposition of Company Securities:

(1)

as a bona fide gift to a charity or educational institution;

(2)

as a bona fide gift to an immediate family member of the undersigned or to a trust formed for the benefit of an immediate family member of the undersigned (for purposes of this lock-up agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin);

(3)

in the case of a natural person, the transfer of any or all of the Lock-Up Shares owned by the undersigned, either during his or her lifetime or on death, by will or intestate succession to a member of the immediate family of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned and/or a member or members of his or her immediate family; or

(4)

in the case of a non-natural person, distributions of any or all of the Lock-Up Shares held by the undersigned to general or limited partners or stockholders or members of the undersigned;

provided that (1) the Representatives receive a signed lock-up agreement for the balance of the Lock-Up Period from each donee or trustee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not required to be reported in any public report or filing with the Commission, or otherwise and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers.

In addition, the undersigned agrees that, without the prior written consent of the Representatives, it will not, during the Lock Up Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or Series B Preferred Stock or any security convertible into or exercisable or exchangeable for Common Stock or Series B Preferred Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock and Series B Preferred Stock except in compliance with the foregoing restrictions.

Furthermore, during the Lock-Up Period, the undersigned may sell shares of Common Stock and Series B Preferred Stock purchased by the undersigned on the open market following the Offerings if and only if (i) such sales are not required to be reported in any public report or filing with the Commission, or otherwise, and (ii) the undersigned does not otherwise voluntarily effect any public filing or report regarding such sales.

B-3

Notwithstanding the foregoing restrictions, the Representatives agree that the undersigned may establish a trading plan under Exchange Act Rule 10b5-1 during the Company’s next permitted xxxxxxx xxxxxxx window period pursuant to the Company’s xxxxxxx xxxxxxx policy; provided that (i) the trading plan terms specifically provide for sales transactions to commence only after the expiration of the Lock-up Period, and (ii) no public announcement is made of the establishment of such trading plan.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this lock-up agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this lock-up agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreements do not become effective prior to May 23, 2014, or if the Underwriting Agreements (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock and Series B Preferred Stock to be sold thereunder, the undersigned shall be released from, all obligations under this lock-up agreement. The undersigned understands that the Underwriters are entering into the Underwriting Agreements and proceeding with the sales pursuant to the Underwriting Agreements in reliance upon this lock-up agreement.

This lock-up agreement and any claim, controversy or dispute arising under or related to this lock-up agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Very truly yours,
