Ladies and Gentlemen:

Public Storage (the “Company”), a Maryland real estate investment trust (“REIT”), proposes to issue and sell an aggregate of 12,000,000 shares (the “Firm Shares”) of its Depositary Shares (the “Depositary Shares”), each representing 1/1,000 of a 5.05% Cumulative Preferred Share of Beneficial Interest, Series G, stated value $25,000 per share (the “Preferred Shares”), to you and the other underwriters named in Schedule I hereto (collectively, the

“Underwriters”) for whom you are acting as Representatives (the “Representatives”). The Company also proposes to sell to the Underwriters, upon the terms and conditions set forth in Section 1(b) hereof, up to an additional 1,800,000 Depositary Shares (the “Additional Shares”). The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.”

The shares of Preferred Shares represented by the Shares will, when issued, be deposited by the Company against delivery of Depositary Receipts (“Depositary Receipts”) to be issued by Computershare Trust Company, N.A., as Depositary (the “Depositary”), under a Deposit Agreement (the “Deposit Agreement”) among the Company, the Depositary, and the holders from time to time of the Depositary Receipts issued thereunder. Each Depositary Receipt will represent one or more Depositary Shares.

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

1. Agreements to Sell and Purchase .

(a) On the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions of this Agreement, the Company agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of $24.2329244791667 per Share (the “purchase price per share”), the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto (or such number of Firm Shares increased as set forth in Section 9 hereof).

(b) The Company also agrees, subject to all the terms and conditions set forth herein, to sell to the Underwriters, and, upon the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions set forth herein, the Underwriters shall have the right to purchase from the Company, at the purchase price per share, plus accumulated dividends, if any, on an Additional Share to the date of purchase, pursuant to an option (the “over-allotment option”) which may be exercised at any time and from time to time prior to 9:00 P.M., New York City time, on the 30th day after the date of the Prospectus (as defined in Section 4) (or, if such 30th day shall be a Saturday or Sunday or a holiday, on the next business day thereafter when the New York Stock Exchange (the “NYSE”) is open for trading), up to an aggregate of 1,800,000 Additional Shares. Additional Shares may be purchased only for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. Upon any exercise of the over-allotment option, each Underwriter, severally and not jointly, agrees to purchase from the Company the number of Additional Shares (subject to such adjustments as you may determine in order to avoid fractional shares) which bears the same proportion to the number of Additional Shares to be purchased by the Underwriters as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule I hereto (or such number of Firm Shares increased as set forth in Section 9 hereof) bears to the aggregate number of Firm Shares.

5. Agreements of the Company . The Company agrees with the Underwriters as follows:

(a) The Company will not, either prior to the Effective Date or thereafter during such period as the Prospectus is required by law to be delivered in connection with sales of the Shares by any Underwriter or any dealer (including in circumstances where such requirement may be satisfied pursuant to Rule 172), file any amendment or supplement to the Registration Statement or the Prospectus, unless a copy thereof shall first have been submitted to the Representatives within a reasonable period of time prior to the filing thereof and the Representatives shall not have objected thereto in good faith.

(b) The Company will notify the Representatives promptly, and will confirm such advice in writing, (1) when any post-effective amendment to the Registration Statement becomes effective, (2) of the receipt of any comments from or any request by the Commission for amendments or supplements to the Registration Statement, any Preliminary Prospectus or the Prospectus or for additional information, (3) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, any notice objecting to its use or the initiation of any proceedings for that purpose or the threat thereof, (4) of the happening of any event during the period mentioned in the second sentence of Section 5(e) that in the judgment of the Company makes any statement made in the Registration Statement, any Preliminary Prospectus or the Prospectus untrue or that requires the making of any changes in the Registration Statement, any Preliminary Prospectus or the Prospectus in order to make the

13

statements therein, in light of the circumstances in which they are made, not misleading, and (5) of receipt by the Company or any representative or attorney of the Company of any other communication from the Commission relating to the Company, the Registration Statement, any Preliminary Prospectus or the Prospectus. If at any time the Commission shall issue any order suspending the effectiveness of the Registration Statement, the Company will make every reasonable effort to obtain the withdrawal of such order at the earliest possible moment.

(c) The Company will furnish to the Representatives, without charge, four copies of the signed copies of the Registration Statement and of any post-effective amendment thereto, including financial statements and schedules, and all exhibits thereto (including any document filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus) and will furnish to the Representatives, without charge, for transmittal to each of the other Underwriters, copies of the Registration Statement and any post-effective amendment thereto, including financial statements and schedules but without exhibits.

(d) The Company will comply with all the provisions of any undertakings contained in the Registration Statement.

(e) The Company will deliver to each of the Underwriters, without charge, as many copies of the Prospectus, each Issuer Free Writing Prospectus or any amendment or supplement thereto as the Representatives may reasonably request. The Company consents to the use of the Prospectus, each Issuer Free Writing Prospectus or any amendment or supplement thereto by the several Underwriters and by all dealers to whom the Shares may be sold, both in connection with the offering or sale of the Shares and for any period of time thereafter during which the Prospectus is required by law to be delivered in connection therewith (including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Act).

The Company will prepare a final term sheet (the “Final Term Sheet”) reflecting the final terms of the Shares, in form and substance satisfactory to the Representatives, and shall file such Final Term Sheet as an Issuer Free Writing Prospectus pursuant to Rule 433 prior to the close of business two business days after the date hereof; provided that the Company shall provide the Representatives with copies of any such Final Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object.

14

(g) During the period of five years commencing on the date hereof, the Company will furnish to each of the Representatives and each other Underwriter who may so request copies of such financial statements and other periodic and special reports as the Company may from time to time distribute generally to the holders of any class of its capital stock, and will furnish to each of the Representatives and each other Underwriter who may so request a copy of each annual or other report it shall be required to file with the Commission.

(h) The Company will make generally available to holders of its securities as soon as may be practicable but in no event later than the last day of the fifteenth full calendar month following the calendar quarter in which the Effective Date falls, an earnings statement (which need not be audited but shall be in reasonable detail), with respect to the Company, the Subsidiaries and the Partnerships, for a period of 12 months commencing after the Effective Date of the Registration Statement, and satisfying the provisions of Section 11(a) of the Act (including Rule 158 thereunder) and will file such earnings statement as an exhibit to the next periodic report required by Section 13 or 15(d) of the Exchange Act covering the period when the earnings statement is released.

(j) The Company will not at any time, directly or indirectly, take any action intended, or which might reasonably be expected, to cause or result in, or which will constitute, stabilization of the price of the Shares to facilitate the sale or resale of any of the Shares in violation of the Act.

15

(m) The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, represents and agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company and the Representatives, it has not made and will not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Act. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(a) The Company agrees to indemnify and hold harmless each of you and each other Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or arising out of or based upon 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, except insofar as such losses, claims, damages, liabilities or expenses arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission which has been made therein or omitted therefrom in reliance upon and in conformity with the information relating to such Underwriter furnished in writing to the Company by or on behalf of any Underwriter through you expressly for use in connection therewith. The foregoing indemnity agreement shall be in addition to any liability which the Company may otherwise have.

(b) If any action, suit or proceeding shall be brought against any Underwriter or any person controlling any Underwriter in respect of which indemnity may be sought against the Company, such Underwriter or such controlling person shall promptly notify the Company

23

(but failure to so notify the Company shall not relieve the Company from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement) and the Company shall assume the defense thereof, including the employment of counsel and payment of all fees and expenses; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. Such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action, suit or proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless (i) the Company has agreed in writing to pay such fees and expenses, (ii) the Company has failed promptly to assume the defense and employ counsel, or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Underwriter or such controlling person and the Company and such Underwriter or such controlling person shall have been advised by its counsel that representation of such indemnified party and the Company by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the Company shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Underwriter or such controlling person). It is understood, however, that the Company shall, in connection with any one such action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Underwriters and controlling persons not having actual or potential differing interests with you or among themselves, which firm shall be designated in writing by the Representatives, and that all such fees and expenses shall be reimbursed as they are incurred. The Company shall not be liable for any settlement of any such action, suit or proceeding effected without its written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, suit or proceeding, the Company agrees to indemnify and hold harmless any Underwriter, to the extent provided in the preceding paragraph, and any such controlling person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with respect to information relating to such Underwriter furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus, any Preliminary Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement thereto. If any action, suit or proceeding shall be brought against the Company, any of its directors, any such officer, or any such controlling person based on the

24

Registration Statement, the Prospectus, any Preliminary Prospectus, or any Issuer Free Writing Prospectus or any amendment or supplement thereto, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph (c), such Underwriter shall have the rights and duties given to the Company by paragraph (b) above (except that if the Company shall have assumed the defense thereof such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel shall be at such Underwriter’s expense), and the Company, its directors, any such officer, and any such controlling person shall have the rights and duties given to the Underwriters by paragraph (b) above. The foregoing indemnity agreement shall be in addition to any liability which the Underwriters may otherwise have.

(d) If the indemnification provided for in this Section 7 is unavailable to an indemnified party under paragraph (a) or (c) hereof in respect of any losses, claims, damages, liabilities or expenses referred to therein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company 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 bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating any claim or defending any such action, suit or proceeding. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price of the Shares underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation

25

(within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to the respective numbers of Firm Shares set forth opposite their names in Schedule I hereto (or such numbers of Firm Shares increased as set forth in Section 9 hereof) and not joint.

(f) No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action, suit or 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or 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 any indemnified party.

(g) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(b) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. Notwithstanding the immediately preceding sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, an indemnifying party shall not be liable for any settlement of the nature contemplated by Section 7(b) effected without its consent if such indemnifying party (i) reimburses such indemnified party in accordance with such request to the extent such indemnifying party considers such request to be reasonable and (ii) provides written notice to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

(h) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, its directors or officers, or any person controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 7.

8. Expenses .

The Company agrees to pay the following costs and expenses and all other costs and expenses incident to the performance by it of its obligations hereunder: (i) the preparation, printing or reproduction, and filing with the Commission of the Registration Statement

26

(including financial statements and exhibits thereto), the Preliminary Prospectus, the Prospectus, any Permitted Free Writing Prospectus and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging and any costs associated with electronic delivery) of such copies of the Registration Statement, the Preliminary Prospectus, the Prospectus, any Permitted Free Writing Prospectus, the Incorporated Documents, and all amendments or supplements to any of them, as may be reasonably requested for use in connection with the offering and sale of the Shares; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Shares and the Preferred Shares, including any stamp taxes in connection with the original issuance and sale of the Shares and the Preferred Shares; (iv) the printing (or reproduction) and delivery of this Agreement, the preliminary and supplemental Blue Sky Memoranda, the Deposit Agreement and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Shares and the Preferred Shares; (v) the fees and expenses of the Depositary, including the fees and disbursements of counsel for the Depositary, if any; (vi) the registration of the Shares under the Exchange Act and the listing of the Shares on the NYSE; (vii) the registration or qualification of the Shares and the Preferred Shares for offer and sale under the securities or Blue Sky laws of the several states as provided in Section 5(f) hereof (including the reasonable fees, expenses and disbursements of counsel for the Underwriters relating to the preparation, printing or reproduction, and delivery of the preliminary and supplemental Blue Sky Memoranda and such registration and qualification); (viii) the filing fees and the fees and expenses of counsel for the Underwriters in connection with any filings required to be made with the Financial Industry Regulatory Authority, Inc.; (ix) the transportation and other expenses incurred by or on behalf of Company representatives in connection with presentations to prospective purchasers of the Shares; (x) the fees and expenses of the Company’s accountants and the fees and expenses of counsel (including local and special counsel) for the Company; and (xi) the costs and expenses (including without limitation any damages or other amounts payable in connection with legal or contractual liability) associated with the reforming of any contracts for sale of the Shares made by the Underwriters caused by a breach of the representation in Section 4(c).

9. Effective Date of Agreement.

This Agreement shall become effective: (i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at the time this Agreement is executed and delivered, it is necessary for a post-effective amendment to the Registration Statement to be declared or become effective before the offering of the Shares may commence, when notification of the effectiveness of such post-effective amendment has been released by the Commission. Until such time as this Agreement shall have become effective, it may be terminated by the Company, by notifying you, or by you, as Representatives of the several Underwriters, by notifying the Company.

If any one or more of the Underwriters shall fail or refuse to purchase Shares which it or they are obligated to purchase hereunder on the Closing Date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters are obligated but fail or refuse to purchase is not more than one-tenth of the aggregate number of Shares which the Underwriters are obligated to purchase on the Closing Date, each non-defaulting Underwriter shall be obligated, severally, in the proportion which the number of Firm Shares set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Shares set forth

27

opposite the names of all non-defaulting Underwriters, to purchase the Shares which such defaulting Underwriter or Underwriters are obligated, but fail or refuse, to purchase. If any one or more of the Underwriters shall fail or refuse to purchase Shares which it or they are obligated to purchase on the Closing Date and the aggregate number of Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Shares which the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to you and the Company for the purchase of such Shares by one or more non-defaulting Underwriters or other party or parties approved by you and the Company are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case which does not result in termination of this Agreement, either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement. The term “Underwriter” as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with your approval and the approval of the Company, purchases Shares which a defaulting Underwriter is obligated, but fails or refuses, to purchase.

Any notice under this Section 9 may be given by telegram, telecopy or telephone but shall be subsequently confirmed by letter.

10. Termination .

This Agreement shall be subject to termination in your absolute discretion, without liability on the part of any Underwriter to the Company by notice to the Company, if prior to the Closing Date or any Option Closing Date (if different from the Closing Date and then only as to the Additional Shares, as the case may be), (i) there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus or the General Disclosure Package, any material adverse change, or any development involving a prospective material adverse change, in the condition, financial or otherwise, or in the business, properties, net worth or results of operations of the Company, the Subsidiaries or the Partnerships, whether or not arising in the ordinary course of business, (ii) trading in securities generally on the NYSE, the NYSE American, Nasdaq Global Select Market or the Nasdaq Global Market shall have been suspended or materially limited, (iii) a general moratorium on commercial banking activities in New York or California shall have been declared by either federal or state authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities or other international or domestic calamity, crisis or change in political, financial or economic conditions, the effect of which on the financial markets of the United States is such as to make it, in your judgment, impracticable or inadvisable to commence or continue the offering of the Shares at the offering price to the public set forth on the cover page of the Prospectus or to enforce contracts for the resale of the Shares by the Underwriters. Notice of such termination may be given to the Company by telegram, telecopy or telephone and shall be subsequently confirmed by letter.

Neither the term “successor” nor the term “successors and assigns” as used in this Agreement shall include a purchaser from any Underwriter of any of the Shares in his status as such purchaser.

13. Applicable Law; Counterparts .

This Agreement may be signed in various counterparts which together constitute one and the same instrument. If signed in counterparts, this Agreement shall not become effective unless at least one counterpart hereof shall have been executed and delivered on behalf of each party hereto.

14. No Advisory or Fiduciary Relationships .

29

Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering of the Shares (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with the offering of the Shares or the process leading thereto.

15. Patriot Act .

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.
