The Company shall use its commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission as soon as practicable after the initial filing thereof but in any event not later than the earlier of (i) six (6) months after the date of filing of the Registration Statement and (ii) twelve (12) months after the GSE Approval Date. Any Shelf Registration Statement shall provide for the resale from time to time, and pursuant to any method or combination of methods legally available (including, without limitation, an Underwritten Offering, a direct sale to purchasers or a sale through brokers or agents, which may include sales over the internet) by the Holders of any and all Registrable Shares.

(b) IPO Registration. If the Company proposes to file a registration statement on Form S-1 or such other form under the Securities Act providing for the initial public offering of shares of Common Stock (the “IPO Registration Statement”), the Company will notify in writing each Holder of the filing within ten (10) Business Days after the initial filing and afford each Holder an opportunity to include in the IPO Registration Statement all or any part of the Registrable Shares then held by such Holder. Each Holder desiring to include in the IPO Registration Statement all or part of the Registrable Shares held by such Holder shall, within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in writing, and in such notice shall inform the Company of the number of Registrable Shares such Holder wishes to include in the IPO Registration Statement. Any election by any Holder to include any Registrable Shares in the IPO Registration Statement will not affect the inclusion of such Registrable Shares in the Shelf Registration Statement until such Registrable Shares have been sold under the IPO Registration Statement.

(i) Right to Terminate IPO Registration. The Company shall have the right to terminate or withdraw the IPO Registration Statement initiated by it and referred to in this Section 2(b) prior to the effectiveness of such registration whether or not any Holder has elected to include Registrable Shares in such registration; provided, however, the Company must provide each Holder that elected to include any Registrable Shares in such IPO Registration Statement prompt written notice of such termination or withdrawal. Furthermore, in the event the IPO Registration Statement is not declared effective within one hundred thirty (130) days following the initial filing of the IPO Registration Statement, unless a road show for the Underwritten Offering pursuant to the IPO Registration Statement is actually in progress at such time, the Company shall promptly provide a new written notice to all Holders giving them another opportunity to elect to include Registrable

EXHIBIT 4.2

Shares in the pending IPO Registration Statement. Each Holder receiving such notice shall have the same election rights afforded such Holder as described in clause (b) above.

(ii) Selection of Underwriter. The Company shall have the sole right to select the managing underwriter(s) for its initial public offering, regardless of whether any Registrable Shares are included in the IPO Registration Statement or otherwise.

(iii) Shelf Registration not Impacted by IPO Registration Statement. The Company’s obligation to file the Shelf Registration Statement pursuant to Section 2(a) hereof shall not be affected by the filing or effectiveness of the IPO Registration Statement. In addition, the Company’s obligation to file and use its commercially reasonable efforts to cause to become and keep effective the Shelf Registration Statement pursuant to Section 2(a) hereof shall not be affected by the filing or effectiveness of an IPO Registration Statement; provided, however, if the Company files an IPO Registration Statement before the effective date of the Shelf Registration Statement, the Company shall have the right to defer causing the Commission to declare such Shelf Registration Statement effective until up to 60 days after the closing date of its initial public offering pursuant to the IPO Registration Statement.

(c) Issuer Free Writing Prospectus. The Company represents and agrees that, unless it obtains the prior consent of Review Counsel or the consent of the managing underwriter in connection with any Underwritten Offering of Registrable Shares, and each Holder represents and agrees that, unless it obtains the prior consent of the Company and any such underwriter, it will not make any offer relating to the Shares that would constitute an “issuer free writing prospectus,” as defined in Rule 433 (an “Issuer Free Writing Prospectus”), or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. The Company represents that any Issuer Free Writing Prospectus will not include any information that conflicts with the information contained in any Registration Statement or the related Prospectus, and any Issuer Free Writing Prospectus, when taken together with the information in such Registration Statement and the related Prospectus, will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(d) Underwriting. The Company shall advise all Holders of the lead managing underwriter for the Underwritten Offering proposed under the IPO Registration Statement. The right of any such Holder’s Registrable Shares to be included in the IPO Registration Statement pursuant to Section 2(b) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Shares in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Shares through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter(s) selected for such underwriting and complete and execute any questionnaires, powers of attorney, indemnities, custody agreements, securities escrow agreements and other documents, including opinions of counsel, reasonably required under the terms of such underwriting, and furnish to the Company such information as the Company may reasonably request in writing for inclusion in the Registration Statement; provided, however, that no Holder shall be required to make any representations or warranties to or agreements with the Company or

EXHIBIT 4.2

the underwriters other than representations, warranties or agreements regarding such Holder and such Holder’s intended method of distribution and any other representation required by law or reasonably requested by the underwriters. Notwithstanding any other provision of this Agreement, if the managing underwriter(s) determine(s) in good faith that marketing factors require a limitation on the number of shares to be included, then the managing underwriter(s) may exclude shares (including Registrable Shares) from the IPO Registration Statement and Underwritten Offering, and any shares included in such IPO Registration Statement and Underwritten Offering shall be allocated first, to the Company, and second, to each of the Holders requesting inclusion of their Registrable Shares in such IPO Registration Statement (on a pro rata basis based on the total number of Registrable Shares then held by each such Holder who is requesting inclusion); provided, however, that the number of Registrable Shares to be included in the IPO Registration Statement shall not be reduced unless all other securities of the Company held by (i) officers, directors, other employees of the Company and consultants and (ii) other holders of the Company’s capital stock with registration rights that are inferior (with respect to such reduction) to the registration rights of the Holders set forth herein, are first entirely excluded from the underwriting and registration; provided, further, however, that Holders of Registrable Shares shall be permitted to include Registrable Shares comprising at least 25% of the total securities included in the Underwritten Offering proposed under the IPO Registration Statement.

By electing to include the Registrable Shares in the IPO Registration Statement, the Holder of such Registrable Shares shall be deemed to have agreed not to effect any public sale or distribution of securities of the Company of the same or similar class or classes of the securities included in the IPO Registration Statement or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 or Rule 144A under the Securities Act, during such periods as reasonably requested (but in no event for a period longer than thirty (30) days prior to and one hundred eighty (180) days following the effective date of the IPO Registration Statement) by the representatives of the underwriters, if an Underwritten Offering, or by the Company in any other registration.

If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the managing underwriter(s), delivered at least ten (10) Business Days prior to the effective date of the IPO Registration Statement. Any Registrable Shares excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration.

(e) Expenses. The Company shall pay all Registration Expenses in connection with the registration of the Registrable Shares pursuant to this Agreement. Each Holder participating in a registration pursuant to this Section 2 shall bear such Holder’s proportionate share (based on the total number of Registrable Shares sold in such registration) of all discounts and commissions payable to underwriters or brokers and all transfer taxes and transfer fees in connection with a registration of Registrable Shares pursuant to this Agreement.

EXHIBIT 4.2

(f) Penalty Provisions. If the Company does not file a Registration Statement registering the resale of the Registrable Shares within six (6) months after the GSE Approval Date, other than as a result of the Commission being unable to accept such filing (a “Registration Default”), then each of the Executive Officers shall lose his opportunity to earn 50% of his bonus for 2013 and he shall, for each additional 30-day period following the Registration Default for which the Registration Default shall have not been cured, lose his opportunity for an additional 10% of his bonus opportunity for 2013, so that he will have no bonus opportunity for 2013 if the Registration Default continued for five such 30-day periods.

3. Special Election Meeting.

(a) If a Registration Statement registering the resale of the Registrable Shares has not been declared effective by the Commission, or the Registrable Shares have not been listed for trading on the New York Stock Exchange or the NASDAQ Global Market prior to the earlier of (i) six (6) months after the filing of the Registration Statement and (ii) twelve (12) months after the GSE Approval Date (the “Trigger Date”), a special meeting of stockholders (the “Special Election Meeting”) shall be called in accordance with the Amended and Restated Bylaws of the Company. The Special Election Meeting shall occur as soon as possible following the Trigger Date but in no event more than forty-five (45) days after the Trigger Date.

(d) use its commercially reasonable efforts to register or qualify, or obtain exemption from registration or qualification for, all Registrable Shares by the time the applicable Registration Statement is declared effective by the Commission under all applicable state securities or “blue sky” laws of such jurisdictions as FBR or any Holder of Registrable Shares covered by a Registration Statement shall reasonably request in writing, keep each such registration or qualification or exemption effective during the period such Registration Statement is required to be kept effective pursuant to Section 5(a) and do any and all other acts and things that may be reasonably necessary or advisable to enable such Holder to consummate the disposition in each such jurisdiction of such Registrable Shares owned by such Holder; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction or to register as a broker or dealer in such jurisdiction where it would not otherwise be required to qualify but for this Section 5(d) and except as may be required by the Securities Act, (ii) subject itself to taxation in any such jurisdiction, or (iii) submit to the general service of process in any such jurisdiction;

EXHIBIT 4.2

(g) use its commercially reasonable efforts to avoid the issuance of, or if issued, to obtain the withdrawal of, any order enjoining or suspending the use or effectiveness of a Registration Statement or suspending the qualification of (or exemption from qualification of) any of the Registrable Shares for sale in any jurisdiction, as promptly as practicable;

(h) upon request, furnish to each requesting Holder of Registrable Shares covered by a Registration Statement, without charge, one conformed copy of such Registration Statement and any post-effective amendment or supplement thereto (without documents incorporated therein by reference or exhibits thereto, unless requested);

(i) except as provided in Section 6 hereof, upon the occurrence of any event contemplated by Section 5(f)(4) hereof, use its commercially reasonable efforts to promptly prepare a supplement or post-effective amendment to a Registration Statement or the related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Shares, such Prospectus will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(k) in the case of an Underwritten Offering, use its commercially reasonable efforts to furnish to the underwriters a signed counterpart, addressed to each such Holder and the underwriters, of: (i) an opinion of counsel for the Company customary for underwritten public offerings, dated the date of each closing under the underwriting agreement, reasonably satisfactory to the underwriters; and (ii) a “comfort” letter, dated the effective date of such Registration Statement and the date of each closing under the underwriting agreement, signed by the independent public accountants who have certified the Company’s financial statements included in such Registration Statement, covering substantially the same matters with respect to such Registration Statement (and the Prospectus included therein) and with respect to events subsequent to the date of such financial statements, as are customarily covered in accountants’ letters delivered to underwriters in underwritten public offerings of securities and such other financial matters as such Holder and the underwriters may reasonably request and are customarily obtained by underwriters in underwritten offerings;

EXHIBIT 4.2

Registration Statement shall have reasonably objected on the grounds that such Registration Statement or Prospectus or amendment or supplement does not comply in all material respects with the requirements of the Securities Act, such Holder having been furnished with a copy thereof at least two (2) Business Days prior to the filing thereof;

(r) provide and cause to be maintained a registrar and transfer agent for all Registrable Shares covered by any Registration Statement from and after a date not later than the effective date of such Registration Statement;

(s) in connection with any sale or transfer of the Registrable Shares (whether or not pursuant to a Registration Statement) that will result in the securities being delivered no longer being Registrable Shares, cooperate with the Holders and the representative of the underwriters, if any, to facilitate (unless any Registrable Shares shall be in book-entry only form) the timely preparation and delivery of certificates representing the Registrable Shares to be sold, which certificates shall not bear any restrictive transfer legends (other than as required by the Company’s Amended and Restated Certificate of Incorporation, as it may be amended from time to time) and to enable such Registrable Shares to be in such denominations and registered in such names as the representative of the underwriters, if any, or the Holders may request at least three (3) Business Days prior to any sale of the Registrable Shares;

(t) in connection with the initial filing of a Shelf Registration Statement and each amendment thereto with the Commission pursuant to Section 2(a) hereof, cooperate with FBR in connection with the filing with FINRA of all forms and information required or requested by FINRA in order to obtain written confirmation from FINRA that FINRA does not object to the fairness and reasonableness of the underwriting terms and arrangements (or any deemed underwriting terms and arrangements) (each such written confirmation, a “No Objections Letter”) relating to the resale of Registrable Shares pursuant to the Shelf Registration Statement, including, without limitation, information provided to FINRA through its COBRADesk system, and pay all costs, fees and expenses incident to FINRA’s review of the Shelf Registration Statement and the related underwriting terms and arrangements, including, without limitation, all filing fees associated with any filings or submissions to FINRA and the reasonable legal expenses, filing fees and other disbursements of FBR and any other FINRA member that is the Holder of, or is affiliated or associated with an owner of, Registrable Shares included in the Shelf Registration Statement (including in connection with any initial or subsequent member filing);

(u) in connection with the initial filing of a Shelf Registration Statement and each amendment thereto filed with the Commission pursuant to Section 2(a) hereof, provide to FBR and its representatives, the opportunity to conduct due diligence, including, without limitation, an inquiry of the Company’s financial and other records, and make available members of its management for questions regarding information which FBR may request in order to fulfill any due diligence obligation on its part and, concurrent with the initial filing of a Shelf Registration Statement with the Commission pursuant to Section 2(a) hereof and thereafter upon prompt request from FBR, pay to FBR, by wire transfer of immediately available funds, amounts to cover FBR’s reasonable out of pocket expenses associated with its due diligence review of the Shelf Registration Statement and the information contained therein, if any, not to exceed $50,000 in the aggregate;

EXHIBIT 4.2

(v) upon effectiveness of the first Registration Statement filed under this Agreement, take such actions and make such filings as are necessary to effect the registration of the Common Stock under the Exchange Act simultaneously with or immediately following the effectiveness of the Registration Statement; and

(w) in the case of an Underwritten Offering, use its commercially reasonable efforts to cooperate and assist in any filings required to be made with FINRA and in the performance of any due diligence investigation by any underwriter and its counsel (including any “qualified independent underwriter,” if applicable) that is required to be retained in accordance with the rules and regulations of FINRA.

The Company may require the Holders to furnish (and each Holder shall furnish) to the Company such information regarding the proposed distribution by such Holder of such Registrable Shares as the Company may from time to time reasonably request in writing or as shall be required to effect the registration of the Registrable Shares, and no Holder shall be entitled to be named as a selling stockholder in any Registration Statement and no Holder shall be entitled to use the Prospectus forming a part thereof if such Holder does not provide such information to the Company. Any Holder that sells Registrable Shares pursuant to a Registration Statement or as a selling security holder pursuant to an Underwritten Offering shall be required to be named as a selling shareholder in the related prospectus and to deliver a prospectus to purchasers. Each Holder further agrees to furnish promptly to the Company in writing all information required from time to time to make the information previously furnished by such Holder not misleading.

Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5(f)(3) or 5(f)(4) hereof, such Holder will immediately discontinue disposition of Registrable Shares pursuant to a Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus. If so directed by the Company, such Holder will deliver to the Company (at the expense of the Company) all copies in its possession, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Registrable Shares current at the time of receipt of such notice.

6. Black-Out Period

(a) Subject to the provisions of this Section 6 and a good faith determination by a majority of the independent members of the board of directors of the Company (the “Board of Directors”) that it is in the best interests of the Company to suspend the use of the Registration Statement, following the effectiveness of a Registration Statement (and the filings with any international, federal or state securities commissions), the Company, by written notice to FBR and the Holders, may direct the Holders to suspend sales of the Registrable Shares pursuant to a Registration Statement for such times as the Company reasonably may determine is necessary and advisable (but in no event for more than an aggregate of ninety (90) days in any rolling twelve (12) month period commencing on the Closing Date or more than sixty (60) days in any rolling ninety (90) day period), if any of the following events shall occur: (i) the representative of the underwriters of an Underwritten Offering of primary shares by the Company has advised the

EXHIBIT 4.2

Company that the sale of Registrable Shares pursuant to the Registration Statement would have a material adverse effect on the Company’s primary Underwritten Offering; (ii) the majority of the independent members of the Board of Directors of the Company shall have determined in good faith that (A) the offer or sale of any Registrable Shares would materially impede, delay or interfere with any proposed financing, offer or sale of securities, acquisition, merger, tender offer, business combination, corporate reorganization or other significant transaction involving the Company, (B) after the advice of counsel, the sale of Registrable Shares pursuant to the Registration Statement would require disclosure of non-public material information not otherwise required to be disclosed under applicable law, and (C) (x) the Company has a bona fide business purpose for preserving the confidentiality of such transaction or information, (y) disclosure would have a material adverse effect on the Company or the Company’s ability to consummate such transaction, or (z) the proposed transaction renders the Company unable to comply with Commission requirements, in each case under circumstances that would make it impractical or inadvisable to cause the Registration Statement (or such filings) to become effective or to promptly amend or supplement the Registration Statement on a post-effective basis, as applicable; or (iii) the majority of the independent members of the Board of Directors of the Company shall have determined in good faith, after the advice of counsel, that it is required by law, rule or regulation or that it is in the best interests of the Company to supplement the Registration Statement or file a post-effective amendment to the Registration Statement in order to incorporate information into the Registration Statement for the purpose of (1) including in the Registration Statement any prospectus required under Section 10(a)(3) of the Securities Act; (2) reflecting in the prospectus included in the Registration Statement any facts or events arising after the effective date of the Registration Statement or any misstatement or omission in the prospectus (or of the most recent post-effective amendment) that, individually or in the aggregate, represent a fundamental change in the information set forth therein; or (3) including in the prospectus included in the Registration Statement any material information with respect to the plan of distribution not disclosed in the Registration Statement or any material change to such information. Upon the occurrence of any such suspension, the Company shall use its best efforts to cause the Registration Statement to become effective or to promptly amend or supplement the Registration Statement on a post- effective basis or to take such action as is necessary to make resumed use of the Registration Statement compatible with the Company’s best interests, as applicable, so as to permit the Holders to resume sales of the Registrable Shares as soon as possible.

(b) In the case of an event that causes the Company to suspend the use of a Registration Statement (a “Suspension Event”), the Company shall give written notice (a “Suspension Notice”) to FBR and the Holders to suspend sales of the Registrable Shares and such notice shall state generally the basis for the notice and that such suspension shall continue only for so long as the Suspension Event or its effect is continuing and the Company is using its best efforts and taking all reasonable steps to terminate suspension of the use of the Registration Statement as promptly as possible. The Holders shall not effect any sales of the Registrable Shares pursuant to such Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). If so directed by the Company, each Holder will deliver to the Company (at the expense of the Company) all copies other than permanent file copies then in such Holder’s possession of the Prospectus covering the Registrable Shares at the time of receipt of the Suspension Notice. The Holders may recommence effecting sales of the Registrable Shares pursuant to the Registration

EXHIBIT 4.2

Statement (or such filings) following further notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice shall be given by the Company to the Holders and FBR in the manner described above promptly following the conclusion of any Suspension Event and its effect.

(c) Notwithstanding any provision herein to the contrary, if the Company shall give a Suspension Notice pursuant to this Section 6, the Company agrees that it shall extend the period of time during which the applicable Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from the date of receipt by the Holders of the Suspension Notice to and including the date of receipt by the Holders of the End of Suspension Notice and copies of the supplemented or amended Prospectus necessary to resume sales.

7. Indemnification and Contribution

(a) The Company agrees to indemnify and hold harmless (i) each Holder of Registrable Shares and any underwriter (as determined in the Securities Act) for such Holder (including, if applicable, FBR), (ii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) any such Person described in clause (i) (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “Controlling Person”), and (iii) the respective officers, directors, partners, members, employees, representatives and agents of any such Person or any Controlling Person (any Person referred to in clause (i), (ii) or (iii) above may hereinafter be referred to as a “Purchaser Indemnitee”), to the fullest extent lawful, from and against any and all losses, claims, damages, judgments, actions, out-of-pocket expenses, and other liabilities (the “Liabilities”), including without limitation and as incurred, reimbursement of all reasonable costs of investigating, preparing, pursuing or defending any Proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to any Purchaser Indemnitee, joint or several, directly or indirectly related to, based upon, arising out of or in connection with any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto), any Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus (or any amendment or supplement thereto), or any preliminary Prospectus or any other document used to sell the Registrable Shares, or 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 under which they were made, not misleading; provided, however, that (A) the Company shall not be liable in any such case to the extent that such Liabilities arise out of or are based upon any untrue statement or omission or alleged untrue statement or alleged omission made in reliance upon and in conformity with information relating to any Purchaser Indemnitee furnished to the Company or any underwriter in writing by or on behalf of such Purchaser Indemnitee expressly for use therein and (B) in the case of a Suspension Event for which a Suspension Notice is delivered in accordance with Section 6 and actually received by such Holder (provided that a Holder shall be deemed to have received such Suspension Notice (I) when sent by the Company by confirmed electronic email or facsimile if sent during normal business hours of the recipient (or, if not so confirmed or if sent outside normal business hours, on the next business day) and (II) if delivered by mail, upon delivery at the address of the Holder as it appears in the records of the Company), the Company shall not be liable for any Liabilities resulting from a sale of Registrable Shares by any Holder occurring after receipt by such Holder of the Suspension

EXHIBIT 4.2

Notice and prior to delivery by the Company of an End of Suspension Notice (or, if earlier, the time that the suspension period is required to end pursuant to Section 6). The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding (including any governmental investigation), or litigation of which it shall have become aware in connection with the matters addressed by this Agreement which involves the Company or a Purchaser Indemnitee. The indemnity provided for herein shall remain in full force and effect regardless of any investigation made by or on behalf of any Purchaser Indemnitee.

(b) In connection with any Registration Statement in which a Holder of Registrable Shares is participating, and as a condition to such participation, such Holder agrees, severally and not jointly, to indemnify and hold harmless the Company and each Person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act and their respective officers, directors, partners, members, employees, representatives and agents of such Person or Controlling Person to the same extent as the foregoing indemnity from the Company to each Purchaser Indemnitee, but only with reference to untrue statements or omissions or alleged untrue statements or omissions made in reliance upon and in strict conformity with information relating to such Holder furnished to the Company in writing by such Holder expressly for use in such Registration Statement (or any amendment thereto), Prospectus (or any amendment or supplement thereto), Issuer Free Writing Prospectus (or any amendment or supplement thereto) or any preliminary Prospectus. Absent gross negligence or willful misconduct, the liability of any Holder pursuant to this paragraph shall in no event exceed the net proceeds received by such Holder from sales of Registrable Shares pursuant to such Registration Statement (or any amendment thereto), Prospectus (or any amendment or supplement thereto), Issuer Free Writing Prospectus (or any amendment or supplement thereto) or any preliminary Prospectus.

(c) If any Proceeding (including any governmental or regulatory investigation) or demand shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to paragraph (a) or (b) above, such Person (the “Indemnified Party”) shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing of the commencement thereof (but the failure to so notify an Indemnifying Party shall not relieve it from any liability which it may have under this Section 7, except to the extent the Indemnifying Party is materially prejudiced by the failure to give notice), and the Indemnifying Party, upon request of the Indemnified Party(ies), shall retain a single counsel (and a single local counsel) reasonably satisfactory to the Indemnified Party(ies) to represent the Indemnified Party(ies) and any others the Indemnifying Party may reasonably designate in such Proceeding and shall pay the reasonable fees and expenses actually incurred by such counsel related to such Proceeding. Notwithstanding the foregoing, in any such Proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party, unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed in writing to the contrary, (ii) the Indemnifying Party failed within a reasonable time after notice of commencement of the action to assume the defense and employ counsel reasonably satisfactory to the Indemnified Party, (iii) the Indemnifying Party and its counsel do not actively and vigorously pursue the defense of such action or (iv) the named parties to any such action (including any impleaded parties) include both such Indemnified Party and Indemnifying Party, or any Affiliate of the Indemnifying Party, and such Indemnified Party shall have been reasonably advised by counsel that, either (x) there may be one or more legal defenses

EXHIBIT 4.2

available to it which are different from or additional to those available to the Indemnifying Party or such Affiliate of the Indemnifying Party or (y) a conflict may exist between such Indemnified Party and the Indemnifying Party or such Affiliate of the Indemnifying Party (in which case the Indemnifying Party shall not have the right to assume nor direct the defense of such action on behalf of such Indemnified Party; it being understood, however, that the Indemnifying Party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Indemnified Parties, which firm shall be designated in writing by those Indemnified Parties who sold a majority of the Registrable Shares sold by all such Indemnified Parties and any such separate firm for the Company, the directors, the officers and such control Persons of the Company as shall be designated in writing by the Company). The Indemnifying Party shall not be liable for any settlement of any Proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent or if there is a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify any Indemnified Party from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened Proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement (i) includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding and (ii) does not include a statement as to or an admission of, fault, culpability or a failure to act by or on behalf of the Indemnified Party.

(d) If the indemnification provided for in paragraphs (a) and (b) of this Section 7 is for any reason held to be unavailable to an Indemnified Party in respect of any Liabilities referred to therein (other than by reason of the exceptions provided therein) or is insufficient to hold harmless a party indemnified thereunder, then each Indemnifying Party under such paragraphs, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Liabilities (i) in such proportion as is appropriate to reflect the relative benefits of the Indemnified Party on the one hand and the Indemnifying Party(ies) on the other in connection with the statements or omissions that resulted in such Liabilities, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Indemnifying Party(ies) and the Indemnified Party, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and any Purchaser Indemnitees on the other 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 or by such Purchaser Indemnitees and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The parties agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if such Indemnified Parties were treated as one entity for such purpose), or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d) above. The amount paid or payable by an Indemnified Party as a result of any Liabilities referred to in Section 7(d) above shall

EXHIBIT 4.2

be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses actually incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall a Purchaser Indemnitee be required to contribute any amount in excess of the amount by which the net proceeds received by such Purchaser Indemnitee from sales of Registrable Shares exceeds the amount of any damages that such Purchaser Indemnitee has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. For purposes of this Section 7, each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) FBR or a Holder of Registrable Shares shall have the same rights to contribution as FBR or such Holder, as the case may be, and each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) the Company, and each officer, director, partner, employee, representative, agent or manager of the Company shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or Proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 7 or otherwise, except to the extent that any party is materially prejudiced by the failure to give notice. 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.

(f) The indemnity and contribution agreements contained in this Section 7 will be in addition to any liability which the Indemnifying Parties may otherwise have to the Indemnified Parties referred to above. The Purchaser Indemnitees’ obligations to contribute pursuant to this Section 7 are several in proportion to the respective number of Registrable Shares sold by each of the Purchaser Indemnitees hereunder and not joint.

8. Market Stand-off Agreement

Each Holder hereby agrees that it shall not, to the extent requested by the Company or an underwriter of securities of the Company, directly or indirectly sell, offer to sell (including without limitation any short sale), grant any option or otherwise transfer or dispose of any Registrable Shares or other shares of Common Stock of the Company or any securities convertible into or exchangeable or exercisable for shares of Common Stock of the Company then owned by such Holder (other than to donees or partners of the Holder who agree to be similarly bound) (i) for a period (x) in the case of (I) the Company and each of is officers, directors, managers and employees, in each case to the extent such person or entity holds shares of Common Stock or securities convertible into or exchangeable or exercisable for shares of Common Stock, and (II) all Holders that are selling shares pursuant to the IPO Registration Statement, in each case beginning thirty (30) days prior to the effective date of, and continuing for one hundred eighty (180) days following the effective date of, the IPO Registration Statement to the Company; and (y) in the case of all other Holders, beginning on the effective date of, and continuing for sixty (60) days following the effective date of the IPO Registration Statement of the Company, or (ii) for a period of sixty (60) days following the effective date of an IPO Registration Statement of the Company

EXHIBIT 4.2

filed under the Securities Act; provided, however, with respect to the individuals and entities listed above in (x), that if (A) during the last 17 days of the 180-day period following the effective date of the IPO Registration Statement, the Company releases earnings results or material news or a material event relating to the Company occurs or (B) prior to the expiration of such 180-day period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of such 180-day period, then in each case the such 180-day period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless the managing underwriter(s) waive(s), in writing, such extension; provided, further, however, that:

(a) the restrictions above shall not apply to Registrable Shares sold pursuant to the IPO Registration Statement;

(b) all executive officers and directors of the Company then holding shares of Common Stock of the Company or securities convertible into or exchangeable or exercisable for shares of Common Stock of the Company enter into agreements that are no less restrictive;

(c) the Holders shall be allowed any concession or proportionate release allowed to any officer or director that entered into agreements that are no less restrictive (with such proportion being determined by dividing the number of shares being released with respect to such officer or director by the total number of issued and outstanding shares held by such officer or director); provided, that nothing in this Section 8(c) shall be construed as a right to proportionate release for the executive officers and directors of the Company upon the expiration of the sixty (60) day period applicable to all Holders other than the executive officers and directors of the Company; and

(d) this Section 8 shall not be applicable if a Shelf Registration Statement of the Company filed under the Securities Act has been declared effective prior to the filing of an IPO Registration Statement.

In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the securities subject to this Section 8 and to impose stop transfer instructions with respect to the Registrable Shares and such other securities of each Holder (and the securities of every other Person subject to the foregoing restriction) until the end of such period.

9. Termination of the Company’s Obligation

The Company shall have no obligation pursuant to this Agreement with respect to any Registrable Shares proposed to be sold by a Holder in a registration pursuant to this Agreement if, in the opinion of counsel to the Company, (i) all such Registrable Shares proposed to be sold by a Holder may be sold in a single transaction without any volume or manner of sale restrictions or compliance by the Company with any current public information requirements pursuant to Rule 144 (or any successor or analogous rule) under the Securities Act and (ii) the Registrable Shares have been listed for trading on the New York Stock Exchange or the Nasdaq Global Market.

EXHIBIT 4.2

10. Limitations on Subsequent Registration Rights

From and after the date of this Agreement, the Company shall not, without the prior written consent of Holders beneficially owning not less than a majority of the then outstanding Registrable Shares (provided, however, that for purposes of this Section 10, Registrable Shares that are owned, directly or indirectly, by an Affiliate of the Company shall not be deemed to be outstanding), enter into any agreement with any holder or prospective holder of any securities of the Company that would allow such holder or prospective holder (a) to include such securities in any Registration Statement filed pursuant to the terms hereof, unless, under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the same proportionate extent (based on their respective numbers of registrable shares) as the holders of Registrable Shares of the Holders that is included, and (b) have market stand-off arrangements no more favorable to the holders than those contained in Section 8 of this Agreement.

11. Miscellaneous

(a) Remedies. In the event of a breach by the Company of any of its obligations under this Agreement, each Holder, in addition to being entitled to exercise all rights provided herein or, in the case of FBR, in the Purchase/Placement Agreement, or granted by law, including the rights granted in Section 2(f) hereof and recovery of damages, will be entitled to seek specific performance of its rights under this Agreement. Subject to Section 7, the Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given, without the written consent of the Company and Holders beneficially owning not less than a majority of the then outstanding Registrable Shares; provided, however, that for purposes of this Section 11(b), Registrable Shares that are owned, directly or indirectly, by an Affiliate of the Company shall not be deemed to be outstanding; provided, further, that Sections 2(a), 2(f) and 3 may not be amended, modified or supplemented, and waivers or consents thereto or departures therefrom may not be given, without the written consent of the Company and Holders beneficially owning not less than 75% of the then outstanding Registrable Shares. No amendment shall be deemed effective unless it applies uniformly to all Holders. Notwithstanding the foregoing, a waiver or consent to or departure from the provisions hereof with respect to a matter that relates exclusively to the rights of a Holder whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders may be given by such Holder; provided that the provisions of this sentence may not be amended, modified or supplemented except in accordance with the provisions of the first and second sentences of this paragraph.

The Company agrees that the Holders shall be third party beneficiaries to the agreements made hereunder by FBR and the Company, and each Holder shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights hereunder; provided, however, that such Holder fulfills all of its obligations hereunder.

(g) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY STATE COURT IN THE STATE OF NEW YORK OR ANY FEDERAL COURT SITTING IN NEW YORK IN RESPECT OF ANY PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, AND IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS.

(h) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties hereto that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(k) Adjustment for Stock Splits, etc. Wherever in this Agreement there is a reference to a specific number of shares, then upon the occurrence of any subdivision, combination, or stock dividend of such shares, the specific number of shares so referenced in this Agreement shall automatically be proportionally adjusted to reflect the effect on the outstanding shares of such class or series of stock by such subdivision, combination, or stock dividend.

The indemnification and contribution obligations under Section 7 of this Agreement shall survive the termination of the Company’s obligations under Section 2 of this Agreement.
