upon the terms and conditions set forth in the Prospectus and in accordance with the rules and regulations of the National Association of Securities Dealers, Inc. (the Directed Share Program). The Directed Share Participants shall
have heretofore delivered to the Representatives indications of interest to purchase the Directed Shares in form satisfactory to the Representatives, and any allocation of such Directed Shares among the Directed Share Participants shall be made in
accordance with timely directions received by the Representatives from the Company; provided that under no circumstances shall the Representatives or any Underwriter be liable to the Company or to any Directed Share Participant for any action
taken or omitted in good faith in connection with the Directed Share Program. To the extent that any Directed Shares are not confirmed for purchase on or immediately after the date of this Agreement, such Directed Shares may be offered by the
Underwriters as part of the public offering upon the terms and conditions set forth in the Prospectus.



5. Delivery of and Payment for the Stock. Delivery of and payment for the Firm Stock shall be made at the offices of Latham & Watkins LLP, 885

place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. Upon delivery, the Firm Stock shall be registered in such names and in such denominations as the Representatives shall request in
writing not less than two (2) full business days prior to the First Delivery Date. For the purpose of expediting the checking and packaging of the certificates for the Firm Stock, the Company shall make the certificates representing the Firm Stock

At any time and from time to time on or before the thirtieth (30th) day after the date of this Agreement, the options granted in Section 3 hereof may be exercised, in whole or in part, by written notice being given to the
Company and the Custodian by the Representatives. Such notice shall set forth the aggregate number of shares of Option Stock as to which the options are being exercised, the names in which the shares of Option Stock are to be registered, the
denominations in which the shares of Option Stock are to be issued and the date and time, as determined by the Representatives, when the shares of Option Stock are to be delivered; provided, however, that this date and time shall not be
earlier than the First Delivery Date nor earlier than the second (2nd) business day after the date on which the

indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not
the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (A) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit
or proceeding and (B) does not include a statement as to or admission of fault, culpability or a failure to act by or on behalf of any indemnified party or (ii) be liable for any settlement of any such action effected without its written consent
(which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss or liability by reason of such settlement or judgment.



(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party
under subsections (a), (b) or (c) of this Section 10 in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the
Company, the Principal Subsidiary and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand, from the offering of the Stock 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, the Principal Subsidiary and the Selling Stockholders, on the one hand, and the Underwriters, on
the



---

other hand, with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the Company, the Principal Subsidiary and the Selling Stockholders, on the one hand, and the Underwriters, on the other hand, with respect to such offering shall be deemed to
be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company and the Selling Stockholders, on the one hand, and the total underwriting discounts
and commissions received by the Underwriters with respect to the shares of the Stock purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the shares of the Stock under this Agreement, 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 whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company, the Principal Subsidiary, the Selling Stockholders or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or
omission. The Company, the Principal Subsidiary, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 10(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 into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the
loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for purposes of this Section 10(e), any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Stock
underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged
omission. 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. The Underwriters
obligations to contribute as provided in this Section 10(e) are several in proportion to their respective underwriting obligations and not joint. In no event shall the liability of any Selling Stockholder under this Section 10(e) exceed the amount
that such Selling Stockholder would have been required to pay under Section 10(b) had such indemnification been held to be available thereunder.



11. Defaulting Underwriters.



If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters
shall be obligated to purchase the Stock which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares



---

of the Firm Stock set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of shares of the
Firm Stock set opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such
Delivery Date if the total number of shares of the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Stock to be purchased on such Delivery Date, and
any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Stock which it agreed to purchase on such Delivery Date pursuant to the terms of Section 3 hereof. If the foregoing maximums
are exceeded, the remaining non-defaulting Underwriters, or those other Underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among
them, all of the Stock to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the shares which the defaulting Underwriter or Underwriters agreed but
failed to purchase on such Delivery Date, this Agreement (or, with respect to any Option Delivery Date, the obligation of the Underwriters to purchase, and of the Company and the Selling Stockholders to sell, the Option Stock) shall terminate
without liability on the part of any non-defaulting Underwriter or the Company, the Principal Subsidiary or the Selling Stockholders, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections
8 and 13 hereof. As used in this Agreement, the term Underwriter includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 11,
purchases Firm Stock which a defaulting Underwriter agreed but failed to purchase.



Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Principal Subsidiary and the Selling Stockholders for damages caused by its default. If other
Underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven (7) full business days in order to effect any changes that
in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.



12. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice
given to and received by the Company and the Selling Stockholders prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 9(j), 9(k) or 9(l) shall have occurred or if the Underwriters shall
decline to purchase the Stock for any reason permitted under this Agreement.



13. Reimbursement of Underwriters Expenses. If (a) the Company or any Selling Stockholder shall fail to tender the Stock for delivery to the Underwriters by reason of any failure, refusal or inability on
the part of the Company or the Selling Stockholders to perform any agreement on its 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
and the Selling Stockholders shall reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the
Stock, and promptly upon demand the Company and the Selling Stockholders shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 11 hereof by reason of the default of one or more Underwriters,
neither the Company nor any Selling Stockholder shall be obligated to reimburse any defaulting Underwriter on account of those expenses.



14. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

request. Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Company and the Selling Stockholders shall be entitled to act and rely upon any request, consent, notice or agreement given or made

any investigation made by or on behalf of any of them or any person controlling any of them.
