(iv) Authorization; No Conflicts; Authority.

Neither the Registration Statement nor any amendment thereto, at the effective time of each part thereof, contained or will contain an untrue statement of a material fact or omitted or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Time of Sale, neither (A) the Time of Sale Disclosure Package nor (B) any issuer free writing prospectus, when considered together with the Time of Sale Disclosure Package, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

in light of the circumstances under which they were made, not misleading. The representations and warranties in this Section 2(b)(vii) with respect to any Selling Stockholder apply only to the extent that any statements in or omissions from a Registration Statement, the Time of Sale Disclosure Package or the Prospectus are based on written information concerning such Selling Stockholder furnished to the Company by such Selling Stockholder specifically for use therein (any written information concerning any Selling Stockholder furnished to the Company by such Selling Stockholder specifically for such use being referred to as the “Selling Stockholder Information”); provided, however, that such Selling Stockholder makes no representation or warranty with respect to any statements or omissions made in reliance upon and in conformity with information furnished to the Company in writing by any Underwriter expressly for use in such Registration Statement, Time of Sale Disclosure Package or Prospectus.

(viii) Selling Stockholder Information in Issuer Free Writing Prospectuses. All Selling Stockholder Information furnished by such Selling Stockholder contained in any issuer free writing prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that such Selling Stockholder notified or notifies the Company and the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement, any Preliminary Prospectus or the Prospectus; provided, however, that such Selling Stockholder makes no representation or warranty with respect to any statements or omissions made in reliance upon and in conformity with information furnished to the Company in writing by any Underwriter expressly for use in such issuer free writing prospectus. If at any time following issuance of an issuer free writing prospectus there occurred or occurs an event or development as a result of which such Selling Stockholder Information, if republished immediately following such event or development, conflicted or would conflict with the information then contained in the Registration Statement, any Preliminary Prospectus or the Prospectus or as a result of which such Selling Stockholder Information would include any untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, such Selling Stockholder has promptly notified or will promptly notify the Company and the Representatives and will provide the Company with all necessary information so as to correct such untrue statement or omission.

(c) Effect of Certificates. Any certificate signed by any officer of the Company and delivered to you or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby; any certificate signed by or on behalf of any Selling Stockholder as such and delivered to you or to counsel for the Underwriters shall be deemed a representation and warranty by such Selling Stockholder to each Underwriter as to the matters covered thereby.

3. Purchase, Sale and Delivery of Securities.

(a) Firm Shares. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell [—] Firm Shares, and each Underwriter agrees, severally and not jointly, to purchase from the Company the number of Firm Shares set forth opposite the name of such Underwriter in Schedule II hereto. The purchase price for each Firm Share shall be $[—] per share. The obligation of each Underwriter to the Company shall be to purchase from the Company that number of Firm Shares (to be adjusted by the Representatives to avoid fractional shares) which represents the same proportion of the number of Firm Shares to be sold by the Company pursuant to this Agreement as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule II hereto represents to the total number of Firm Shares to be purchased by all Underwriters pursuant to this Agreement. In making this Agreement, each Underwriter is contracting severally and not jointly; except as provided in paragraph (d) of this Section 3 and in Section 8 hereof, the agreement of each Underwriter is to purchase only the respective number of Firm Shares specified in Schedule II.

(b) Option Shares. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, each Selling Stockholder, with respect to the number of Option Shares set forth opposite the name of such Selling Stockholder in Schedule I hereto, hereby grants to the several Underwriters an option to purchase all or any portion of the Option Shares at the same purchase price as the Firm Shares, for use solely in covering any over-allotments made by the Underwriters in the sale and distribution of the Firm Shares. The option granted hereunder may be exercised in whole or in part at any time (but not more than once) within 30 days after the effective date of this Agreement upon notice (confirmed in writing) by the Representatives to the Company (with a courtesy copy to its counsel at Simpson Thacher & Bartlett LLP) and to the Attorneys-in-Fact setting forth the aggregate number of Option Shares as to which the several Underwriters are exercising the option and the date and time, as determined by you, when the Option Shares are to be delivered, but in no event earlier than the First Closing Date nor earlier than the second business day or later than the tenth business day after the date on which the option shall have been exercised. If the option is exercised, the obligation of each Underwriter shall be to purchase from the Selling Stockholders granting an option to purchase the Option Shares, on a pro rata basis up to [—] Option Shares, that number of Option Shares (to be adjusted by the Representatives to avoid fractional shares) which represents the same proportion that the number of Option Shares granted by each such Selling Stockholder bears to the total number of Option Shares granted by all such Selling Stockholders. The number of Option Shares to be purchased by each Underwriter shall be the same percentage of the total number of Option Shares to be purchased by the several Underwriters as the number of Firm Shares to be purchased by such Underwriter is of the total number of Firm Shares

to be purchased by the several Underwriters, as adjusted by the Representatives in such manner as the Representatives deem advisable to avoid fractional shares. No Option Shares shall be sold and delivered unless the Firm Shares previously have been, or simultaneously are, sold and delivered.

(i) The Securities to be purchased by each Underwriter hereunder, in book-entry form in such authorized denominations and registered in such names as the Representatives may request upon at least forty-eight hours’ prior notice to the Company and the Selling Stockholders, shall be delivered by or on behalf of the Company and the Selling Stockholders to the Representatives, through the facilities of the Depository Trust Company (“DTC”), for the account of such Underwriter, with any transfer taxes payable in connection with the transfer of the Securities to the Underwriters duly paid, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of Federal (same-day) funds to the account specified by the Company and the Selling Stockholders to the Representatives at least forty-eight hours in advance. The time and date of such delivery and payment shall be, with respect to the Firm Shares, 9:30 a.m., New York City time, on [—], 2014 or such other time and date as the Representatives and the Company may agree upon in writing, and, with respect to the Option Shares, 9:30 a.m., New York City time, on the date specified by the Representatives in each written notice given by the Representatives of the Underwriters’ election to purchase such Option Shares, or such other time and date as the Representatives, the Company and the Selling Stockholders may agree upon in writing. Such time and date for delivery of the Firm Shares is herein called the “First Closing Date”, each such time and date for delivery of the Option Shares, if not the First Closing Date, is herein called a “Second Closing Date”, and each such time and date for delivery is herein called a “Closing” or “Closing Date”.

(ii) The documents to be delivered at each Closing by or on behalf of the parties hereto pursuant to Section 5 hereof, including the cross receipt for the Securities and any additional documents requested by the Underwriters pursuant to Section 5(p) hereof, will be delivered at the offices of Latham & Watkins LLP, 555 Eleventh Street, NW, 10^th Floor, Washington, DC 20004 (the “Closing Location”), and the Securities will be delivered to the Representatives, through the facilities of the DTC, for the account of such Underwriter, all at such Closing. A meeting will be held at the Closing Location at 1:00 p.m., New York City time, on the New York Business Day next preceding such Closing, at which meeting the final drafts of the documents to be delivered pursuant to the preceding sentence will be available for review by the parties hereto. For the purposes of this Section 3, “New York Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York City are generally authorized or obligated by law or executive order to close.

(d) Purchase by the Representatives on Behalf of Underwriters. It is understood that each of the Representatives, individually and not as representative of the several Underwriters, may (but shall not be obligated to) make payment to the Company or the Selling Stockholders, on behalf of any Underwriter for the Securities to be purchased by such Underwriter. Any such payment by any of the Representatives shall not relieve any such Underwriter of any of its obligations hereunder. Nothing herein contained shall constitute any of the Underwriters an unincorporated association or partner with the Company or any Selling Stockholder.

4. Covenants.

(a) Covenants of the Company. The Company covenants and agrees with the several Underwriters as follows:

(i) Required Filings. The Company will prepare and file a Prospectus with the Commission containing the Rule 430A Information omitted from the Preliminary Prospectus within the time period required by, and otherwise in accordance with the provisions of, Rules 424(b) and 430A of the Rules and Regulations. If the Company has elected to rely upon Rule 462(b) of the Rules and Regulations to increase the size of the offering registered under the Act and the Rule 462(b) Registration Statement has not yet been filed and become effective, the Company will prepare and file the Rule 462 Registration Statement with the Commission within the time period required by, and otherwise in accordance with the provisions of, Rule 462(b) and the Act. The Company will furnish the Representatives and counsel for the Underwriters a copy of any proposed amendment or supplement to the Registration Statement or Prospectus and will not file any amendment or supplement to the Registration Statement or Prospectus to which you shall reasonably object by notice to the Company after having been furnished a copy a reasonable time prior to the filing.

(ii) Notification of Certain Commission Actions. The Company will advise you, promptly after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or any post-effective amendment thereto or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any issuer free writing prospectus, of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and the Company will promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be issued.

(iii) Continued Compliance with Securities Laws.

(A) Within the time during which a prospectus (assuming the absence of Rule 172) relating to the Securities is required to be delivered under the Act by any Underwriter or dealer, the Company will comply with all requirements imposed upon it by the Act, as now and hereafter amended, and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Securities as contemplated by the provisions hereof, the Time of Sale Disclosure Package and the Prospectus. If during such period any event occurs as a result of which the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) would include an untrue statement of a material fact or omit

to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective investors, the Time of Sale Disclosure Package) to comply with the Act, the Company promptly will (x) notify you of such untrue statement or omission, (y) amend the Registration Statement or supplement the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) (at the expense of the Company) so as to correct such statement or omission or effect such compliance and (z) notify you when any amendment to the Registration Statement is filed or becomes effective or when any supplement to the Prospectus (or, if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) is filed.

(B) If at any time following issuance of an issuer free writing prospectus or Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such issuer free writing prospectus or Written Testing-the-Waters Communication, at the time of such event or development, conflicted or would conflict with the information contained in the Registration Statement, the Time of Sale Disclosure Package or the Prospectus, each as amended to date, relating to the Securities or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company (x) promptly will notify the Representatives of such conflict, untrue statement or omission, (y) if requested by the Representatives, will promptly amend or supplement, at its own expense, such issuer free writing prospectus or Written Testing-the-Waters Communication to eliminate or correct such conflict, untrue statement or omission and (z) promptly will notify you when such amendment or supplement was or is filed with the Commission to the extent required to be filed by the Rules and Regulations.

(iv) Blue Sky Qualifications. The Company shall take or cause to be taken all necessary action to qualify the Securities for sale under the securities laws of such domestic United States jurisdictions as you reasonably designate or as is necessary to effect the distribution of the Directed Stock and to continue such qualifications in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith to qualify as a foreign corporation, subject itself to taxation, qualify as a broker-dealer or execute a general consent to service of process in any jurisdiction.

(v) Provision of Documents.

(vii) Payment and Reimbursement of Expenses. The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, will pay or cause to be paid (A) all expenses (including transfer taxes allocated to the respective transferees) incurred in connection with the delivery to the Underwriters of the Securities, (B) all expenses and fees (including, without limitation, fees and expenses of the Company’s accountants and counsel and any separate counsel of any Selling Stockholder but, except as otherwise provided below, not including fees of the Underwriters’ counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Securities, each Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, any issuer free writing prospectus and any amendment thereof or supplement thereto, and the printing, delivery, and shipping of this Agreement and other underwriting documents, including Blue Sky Memoranda (covering the states and other applicable jurisdictions), (C) all filing fees and reasonable fees and disbursements of the Underwriters’ counsel in an amount not to exceed $25,000 incurred in connection with the qualification of the Securities for offering and sale by the Underwriters or by dealers under the securities or blue sky laws of the states and other jurisdictions which you shall designate, (D) the fees and expenses of the Custodian and any transfer agent or registrar, (E) the filing fees, and reasonable fees and disbursements of Underwriters’ counsel in an amount not to exceed $50,000 incurred in connection with any required review and approval by FINRA of the terms of the sale of the Securities, (F) listing fees, if any, (G) the cost and expenses of the Company relating to investor presentations or any “road show” undertaken in connection with marketing of the Securities, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and 50% of the cost of any aircraft chartered in connection with the road show (and the Underwriters shall pay 50% of the cost of any such aircraft), (H) all fees and disbursements of counsel incurred by the Underwriters in connection with the Directed Stock Program and stamp duties, similar taxes or duties or other taxes, if any, incurred by the Underwriters in connection with the Directed Stock Program and (I) all other costs and expenses of the Company and any Selling Stockholder incident to the performance of its obligations hereunder that are not otherwise specifically provided for herein.

Representatives pursuant to Section 9 hereof or if the sale of the Securities provided for herein is not consummated by reason of any failure, refusal or inability on the part of the Company or the Selling Stockholders to perform any agreement on its or their part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company or the Selling Stockholders is not fulfilled, the Company or such Selling Stockholder will reimburse the several Underwriters for all reasonable out-of-pocket accountable disbursements (including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges) incurred by the Underwriters in connection with their investigation, preparing to market and marketing the Securities or in contemplation of performing their obligations hereunder.

(x) Stockholder Lock-Ups. The Company has caused to be delivered to you prior to the date of this Agreement a letter, in the form of Exhibit A hereto (the “Lock-Up Agreement”), from each individual or entity listed on Schedule III.

(xii) Reporting Requirements. The Company, during the period when a Prospectus relating to the Securities is (or, but for the exception afforded by Rule 172, would be) required to be delivered under the Act, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the regulations thereunder. Additionally, the Company shall report the use of proceeds from the issuance of the Securities to the extent required under Rule 463 under the Act.

(xiii) Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter severally represents and agrees that, unless it obtains the prior written

consent of the Company and the Representatives, it has not made and will not make any offer relating to the Securities that would constitute an issuer free writing prospectus or that would otherwise constitute a free writing prospectus required to be filed with the Commission; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the free writing prospectuses included in Schedule IV. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an issuer free writing prospectus, and has complied and will comply with the requirements of Rules 164 and 433 of the Rules and Regulations applicable to any Permitted Free Writing Prospectus. Each Underwriter severally represents and agrees that, (A) unless it obtains the prior written consent of the Company and the Representatives, it has not distributed, and will not distribute any Written Testing-the-Waters Communication other than those listed on Schedule VI, and (B) any Testing-the-Waters Communication undertaken by it was with entities that are qualified institutional buyers with the meaning of Rule 144A under the Act or institutions that are accredited investors within the meaning of Rule 501 under the Act.

(ii) No Market Stabilization or Manipulation. Such Selling Stockholder has not taken and will not take, directly or indirectly, any action designed to or which might reasonably be expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(iii) Continued Compliance with Securities Laws. Such Selling Stockholder shall immediately notify you if any event occurs, or of any change in the Selling Stockholder Information relating to such Selling Stockholder or the Company or any new information relating to the Company or relating to any matter stated in the Time of Sale Disclosure Package or in the Prospectus or any supplement thereto or any Permitted Free Writing Prospectus, which results in the Time of Sale Disclosure Package or in the Prospectus (as amended or supplemented) or any Permitted Free Writing Prospectus including an untrue statement of a material fact or omitting to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

6. Indemnification and Contribution.

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the 430A Information and any other information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters Communication, or any road show as defined in Rule 433(h) under the Act (a “road show”), or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any out-of-pocket legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that (x) the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by any Representative, or by any Underwriter through any Representative, specifically for use in the preparation thereof; it being understood and agreed that the only information furnished by an Underwriter consists of the information described as such in Section 6(f), and (y) the Company will not be liable in any such case to the extent that

any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from the Selling Stockholder Information.

The Company agrees to indemnify and hold harmless the Designated Underwriter and each person, if any, who controls the Designated Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act (the “Designated Entities”), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Directed Stock Participants in connection with the Directed Stock Program or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) caused by the failure of any Directed Stock Participant to pay for and accept delivery of Directed Stock that the Directed Stock Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Stock Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of the Designated Entities.

(b) Indemnification by the Selling Stockholders. Each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of such Selling Stockholder), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the 430A Information and any other information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters Communication, or any road show, or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any out-of-pocket legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that (x) a Selling Stockholder shall be liable in any such case only to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with Selling Stockholder Information relating to such Selling Stockholder, and (y) in no event shall any Selling Stockholder’s liability hereunder exceed the aggregate amount of net proceeds (after deducting Underwriters’ discounts and commissions) received by such Selling Stockholder from the sale of the Securities pursuant to this Agreement.

(c) Indemnification by the Underwriters. Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company and each Selling Stockholder, its affiliates, directors and officers and each person, if any, who controls the Company and each Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any losses, claims, damages or liabilities to which the Company or the Selling Stockholders may become subject, under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any issuer free writing prospectus, any issuer information that the Company has filed or is required to file pursuant to Rule 433(d) of the Rules and Regulations, or any Written Testing-the-Waters Communication, or any road show, or (ii) arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in conformity with written information furnished to the Company by any Representative, or by any Underwriter through any Representative, specifically for use in the preparation thereof (it being understood and agreed that the only information furnished by an Underwriter consists of the information described as such in Section 6(f)), and will reimburse the Company and the Selling Stockholders for any out-of-pocket legal or other expenses reasonably incurred by the Company or any such Selling Stockholder in connection with investigating or defending against any such loss, claim, damage, liability or action as such expenses are incurred.

(d) Notice and Procedures. Promptly after receipt by an indemnified party under subsection (a), (b) or (c) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure (through the forfeiture of substantive rights or defenses). In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any out-of-pocket legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation unless the indemnified party, based on the advice of counsel, shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to the last paragraph in Section 6(a) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for the Designated Entities for the defense of

any losses, claims, damages and liabilities arising out of the Directed Stock Program if representation of the Underwriters and the Designated Entities by the same counsel would be inappropriate due to actual or potential differing interests between them. An indemnifying party shall not be obligated under any settlement agreement relating to any action under this Section 6 to which it has not agreed in writing. In addition, no indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld or delayed) effect any settlement of any pending or threatened proceeding unless such settlement includes an unconditional release of such indemnified party for all liability on claims that are the subject matter of such proceeding and does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) Contribution; Limitations on Liability; Non-Exclusive Remedy. If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and Selling Stockholders 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 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, the Selling Stockholders or the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (e) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this subsection (e). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) the liability under this subsection of each Selling Stockholder shall be limited to an amount equal to the aggregate gross proceeds after underwriting

discounts and commissions, but before expenses, to such Selling Stockholder from the sale of Securities sold by such Selling Stockholder hereunder. 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 in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Selling Stockholders’ obligations in this subsection (e) to contribute are several in proportion to their respective aggregate gross proceeds received after underwriting discounts and commissions, but before expenses, from the sale of the Securities sold by the Selling Stockholders hereunder and not joint. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies that might otherwise be available to any indemnified party at law or in equity.

(f) Information Provided by the Underwriters. The Underwriters severally confirm and the Company and each Selling Stockholder acknowledges that the statements with respect to the public offering of the Securities by the Underwriters set forth in [—] under the caption “Underwriting” in the Time of Sale Disclosure Package and in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any issuer free writing prospectus.

7. Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company and the Selling Stockholders herein or in certificates delivered pursuant hereto, and the agreements of the several Underwriters, the Company and the Selling Stockholders contained in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, or any Selling Stockholders or any controlling person thereof, and shall survive delivery of, and payment for, the Securities to and by the Underwriters hereunder and any termination of this Agreement.

8. Substitution of Underwriters.

(a) Obligation to Purchase Under Certain Circumstances. If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased does not aggregate to more than 10% of the total amount of Firm Shares set forth in Schedule II hereto, the remaining Underwriters shall be obligated to take up and pay for (in proportion to their respective underwriting obligations hereunder as set forth in Schedule II hereto except as may otherwise be determined by you) the Firm Shares that the withdrawing or defaulting Underwriters agreed but failed to purchase.

(b) Termination Under Certain Circumstances. If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased aggregates more than 10% of the total amount of Firm Shares set forth in Schedule II hereto, and arrangements

satisfactory to you for the purchase of such Firm Shares by other persons are not made within 36 hours thereafter, this Agreement shall terminate. In the event of any such termination neither the Company nor any Selling Stockholder shall be under any liability to any Underwriter (except to the extent provided in Section 4(a)(vii), Section 4(b)(i), Section 4(b)(ii) and Section 6 hereof) nor shall any Underwriter (other than an Underwriter who shall have failed, otherwise than for some reason permitted under this Agreement, to purchase the amount of Firm Shares agreed by such Underwriter to be purchased hereunder) be under any liability to the Company or the Selling Stockholders (except to the extent provided in Section 6 hereof).

(c) Postponement of Closing. If Firm Shares to which a default relates are to be purchased by the non-defaulting Underwriters or by any other party or parties, the Representatives or the Company shall have the right to postpone the First Closing Date for not more than seven business days in order that the necessary changes in the Registration Statement, in the Time of Sale Disclosure Package, in the Prospectus or in any other documents, as well as any other arrangements, may be effected. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 8.

(d) No Relief from Liability. No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability, if any, in respect of such default.

9. Termination.

(a) Right to Terminate. The Representatives of the several Underwriters shall have the right to terminate this Agreement by giving notice as hereinafter specified at any time at or prior to the First Closing Date, and the option referred to in Section 3(b), if exercised, may be cancelled at any time prior to any Second Closing Date, if (i) trading on the NASDAQ Stock Market or New York Stock Exchange shall have been wholly suspended, (ii) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the NASDAQ Stock Market or New York Stock Exchange, by such Exchange or by order of the Commission or any other Governmental Authority, (iii) a banking moratorium shall have been declared by federal or state authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Securities. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(a)(vii), Section 4(b)(i), Section 4(b)(ii) and Section 6 hereof shall at all times be effective.

(b) Notice of Termination. If the Representatives elect to terminate this Agreement as provided in this Section, the Company and an Attorney-in-Fact, on behalf of the Selling Stockholders, shall be notified promptly by the Representatives by telephone, confirmed by letter.

10. Default by One or More of the Selling Stockholders or the Company.

(a) Default by the Selling Stockholders. If one or more of the Selling Stockholders shall fail at any Second Closing Date to sell and deliver the number of Securities

which such Selling Stockholder or Selling Stockholders are obligated to sell hereunder, and the remaining Selling Stockholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Securities to be sold by them hereunder to the total number of Securities to be sold by all Selling Stockholders as set forth in Schedule I, then the Underwriters may at your option, by notice from you to the Company and the non-defaulting Selling Stockholders, to postpone any Second Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, in the Time of Sale Disclosure Package or in the Prospectus or in any other documents or arrangements.

(b) Default by the Company. If the Company shall fail at the First Closing Date to sell and deliver the number of Securities which it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any Underwriter or, except as provided in Section 4(a)(vii), Section 4(b)(i), Section 4(b)(ii) and Section 6 hereof, any non-defaulting party.

(c) No Relief from Liability. No action taken pursuant to this Section shall relieve the Company or any Selling Stockholders so defaulting from liability, if any, in respect of such default.

11. Notices. Except as otherwise provided herein, all communications hereunder shall be in writing and, (i) if to the Underwriters, shall be mailed via overnight delivery service or hand delivered via courier, to Piper Jaffray & Co., 800 Nicollet Mall, Minneapolis, Minnesota 55402, to the attention of Equity Capital Markets and separately, General Counsel, to Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, to the attention of Syndicate Registration, and to Wells Fargo Securities, LLC, 375 Park Avenue, 7^th Floor, New York, New York 10152, to the attention of Equity Syndicate; (ii) if to the Company, shall be mailed or delivered to it at 751 Miller Drive SE, Suite F-1, Leesburg, VA 20175, Attention: Luke Miller, Senior Vice President and General Counsel, with a copy to Kenneth B.

13. Absence of Fiduciary Relationship.

Dear Sirs:

As an inducement to the underwriters (the “Underwriters”) to execute a purchase agreement (the “Purchase Agreement”) providing for a public offering (the “Offering”) of common stock (the “Common Stock”), of K2M Group Holdings, Inc. and any successor (by merger or otherwise) thereto (the “Company”), the undersigned hereby agrees that without, in each case, the prior written consent of Piper Jaffray & Co., Barclays Capital Inc. and Wells Fargo Securities, LLC (collectively, the “Representatives”) during the period specified in the second succeeding paragraph (the “Lock-Up Period”), the undersigned will not: (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into, exercisable or exchangeable for or that represent the right to receive Common Stock (including without limitation, Common Stock which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant) whether now owned or hereafter acquired (the “Undersigned’s Securities”); (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Undersigned’s Securities, whether any such transaction

A-1

described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; (3) make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock; or (4) publicly disclose the intention to do any of the foregoing.

The undersigned agrees that the foregoing restrictions preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Securities even if such Securities would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Securities or with respect to any security that includes, relates to, or derives any significant part of its value from such Securities.

The Lock-Up Period will commence on the date of this Agreement and continue and include the date 180 days after the date of the final prospectus (the “Prospectus”) used to sell Common Stock in the Offering pursuant to the Purchase Agreement, to which you are or expect to become parties.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Purchase Agreement to announce the impending release or waiver by issuing a press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (a) the release or waiver is effected solely to permit a transfer not for consideration, and (b) the transferee has agreed in writing to be bound by the same terms described in this letter that are applicable to the transferor, to the extent and for the duration that such terms remain in effect at the time of the transfer. The undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Common Stock, if any, that the undersigned may purchase in the offering.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Securities (i) as a bona fide gift or gifts, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (iii) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity (1) transfers to another corporation, partnership, limited liability company, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned or (2) distributions of shares of Common Stock or any security convertible into or exercisable for Common Stock to limited partners, limited liability company members or stockholders of the undersigned or holders of similar equity interests in the undersigned, (iv) if the undersigned is a trust, transfers to the beneficiary of such trust, (v) transfers by testate succession or intestate succession, (vi) to any immediate family member or

A-2

any investment fund or other entity controlled or managed by the undersigned, (vii) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (vi), (viii) pursuant to the Purchase Agreement, (ix) in connection with, and to the extent necessary to fund, the payment of taxes due with respect to the vesting of restricted stock, restricted stock units or similar rights to purchase Common Stock pursuant to the Company’s equity incentive plans, (x) in connection with the repurchase of Common Stock by the Company, (xi) acquired by the undersigned in open market transactions after completion of the Offering, (xii) in response to a bona fide third-party takeover bid made to all holders of Common Stock or any other acquisition transaction whereby all or substantially all of the Common Stock are acquired by a third party or (xiii) pursuant to an order of a court or regulatory agency; provided, in the case of clauses (i)-(vii), that (A) such transfer shall not involve a disposition for value, (B) the transferee agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, and (C) no filing by any party under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be made voluntarily in connection with such transfer during the Lock-Up Period; provided, further, in the case of clause (xi), that no filing by any party under Section 16(a) of the Exchange Act shall be required or shall be made voluntarily in connection with such transfer during the Lock-Up Period. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In addition, the foregoing restrictions shall not apply to (i) the exercise of stock options granted pursuant to the Company’s equity incentive plans described in the Prospectus, including the “net” exercise of such options in accordance with their terms and the surrender of Common Stock in lieu of payment in cash of the exercise price and any tax withholding obligations due as a result of such exercise; provided that it shall apply to any of the Undersigned’s Securities issued upon such exercise, or (ii) the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act; provided that no sales of the Undersigned’s Securities shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period, and such a Plan may only be established if no public announcement of the establishment or existence thereof and no filing with the Securities and Exchange Commission or other regulatory authority in respect thereof or transactions thereunder or contemplated thereby, by the undersigned, the Company or any other person, shall be required, and no such announcement or filing is made voluntarily, by the undersigned, the Company or any other person, prior to the expiration of the Lock-Up Period.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Agreement and that upon request, the undersigned will execute any additional documents necessary to ensure the validity or enforcement of this 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 the undersigned shall be released from all obligations under this Agreement if (i) the Company notifies the Underwriters that it does not intend to proceed with the Offering, (ii) the Purchase Agreement does not become effective, or if the

A-3

Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, (iii) the Registration Statement is withdrawn by the Company prior to the completion of the Offering, or (iv) the Offering is not completed by June 30, 2014.

The undersigned understands that the Underwriters are entering into the Purchase Agreement and proceeding with the Offering in reliance upon this Agreement.

A-4

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
