In consideration of the mutual agreements contained herein, the Company and the Underwriters, intending to be legally bound, confirm their agreement as follows:

1.                                      Representations and Warranties of the Company.  The Company represents and warrants to, and agrees with, the several Underwriters that:

(a)                                  The Company has prepared and filed with the Securities and Exchange Commission (the “SEC”), in accordance with the provisions of the Securities Act of 1933, as amended (the “Act”), and the rules and regulations thereunder (the “Regulations”), a registration statement on Form S-3 (File No. 333-156112), including a prospectus, relating to the Notes.  The term “Registration Statement” as used herein means the registration statement (including all exhibits and information incorporated by reference therein) as amended to the date of this Agreement, and includes information (if any) contained in a form of prospectus or prospectus supplement that is deemed retroactively to be part of the Registration Statement, pursuant to Rule 430B under the Act, to be part of the registration statement as of the time specified in Rule 430B.  If it is contemplated, at the time this Agreement is executed, that a post-effective amendment to the Registration Statement will be filed and must be declared effective before the offering of the Notes may commence, the term “Registration Statement” as used herein shall mean the Registration Statement as amended by such post-effective amendment.  If the Company has filed, or files on or after the date of this Agreement, a registration statement to register Notes pursuant to Rule 462(b) under the Act (the “Rule 462(b) Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462(b) Registration Statement.  The term “Base Prospectus” shall mean the base prospectus filed as part of the Registration Statement in the form in which it has most recently been filed with the SEC on or prior to the date of this Agreement.  The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Notes, together with the Base Prospectus, and filed with the SEC pursuant to Rule 424(b) of the Regulations.  The term “Statutory Prospectus” shall mean the Preliminary Prospectus, as amended or supplemented, immediately prior to the Initial Sale Time (as defined below), including any document incorporated by reference therein.  The term “Prospectus” shall mean the final prospectus supplement relating to the Notes, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) after the effective time of the Registration Statement (the “Effective Time”).  The term “Issuer Free Writing Prospectus” shall have the meaning ascribed to it in Rule 433 of the Regulations relating to the Notes, in the form filed or required to be filed with the SEC or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) of the Regulations.  The term “Disclosure Package” shall mean (i) the Statutory Prospectus, (ii) the Issuer Free Writing Prospectus identified in Schedule II hereto, and (iii) any other free writing prospectus defined in Rule 405 of the Regulations that is required to be filed by the Company with the SEC or retained by the Company under Rule 433 of the Regulations and that all parties hereto expressly agree to treat as part of the Disclosure Package (the “Other Free Writing Prospectus”).  For purposes of this Agreement, the “Initial Sale Time” shall mean 2:50 p.m. (Eastern Time) on the date of this Agreement.  All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, the Base Prospectus, a Preliminary Prospectus, the Statutory Prospectus, the Prospectus, the Issuer Free Writing Prospectus, the Other Free Writing Prospectus or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the SEC pursuant to its Interactive Data Electronic Applications (“IDEA”) System.

(b)                                 The Company will not file with the SEC, the Prospectus, any amendment or supplement to the Prospectus or any amendment to the Registration Statement or the Disclosure Package, and will not use, authorize, refer to or file any Issuer Free Writing Prospectus, unless the Representative has received a reasonable period of time to review any such proposed amendment, supplement or Issuer Free Writing Prospectus and consented to the filings thereof, and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective as promptly as possible. Upon reasonable request of the Representative or counsel for the Underwriters, the Company will promptly prepare and file with the SEC, in accordance with the Regulations, any amendments to the Registration Statement or amendments or supplements to the Prospectus or the Disclosure Package that may be necessary or advisable in connection with the distribution of the Notes by the several Underwriters and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective as promptly as possible.  If required, the Company will file any amendment or supplement to the Prospectus or the Disclosure Package with the SEC in the manner and within the time period required by Rule 424(b) or Rule 433 under the Act.  The Company will advise the Representative, promptly after receiving notice thereof, of the time when the Registration Statement or any amendment thereof has been filed or declared effective or the Prospectus or the Disclosure Package, or any amendment or supplement thereto has been filed and will provide evidence to the Representative of each filing or effectiveness.

(c)                                  The Company will advise the Representative immediately, and confirm such advice in writing, (i) when any post-effective amendment to the Registration Statement is filed with the SEC under Rule 462(c) under the Act or otherwise, (ii) when any Rule 462(b) Registration Statement is filed, (iii) of the receipt of any comments from the SEC concerning the Registration Statement, (iv) when any post-effective amendment to the Registration Statement becomes effective, or when any supplement to the Prospectus or the Disclosure Package or any amended Prospectus or Disclosure Package has been filed, (v) of any request of the SEC for amendment or supplementation of the Registration Statement, the Disclosure Package or the Prospectus or for additional information, (vi) during the period when a prospectus is required to be delivered under the Act and Regulations (the “Prospectus Delivery Period”), of the happening of any event as a result of which any Prospectus would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they are made, not misleading, (vii) during the Prospectus Delivery Period, of the need to amend the Registration Statement or supplement to the Prospectus to comply with the Act, (viii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any Preliminary Prospectus or the Prospectus, and (ix) of the suspension of the qualification of any of the Notes for offering or sale in any jurisdiction in which the Underwriters intend to make such offers or sales, or the initiation or threatening of any proceedings for such purpose known to the Company.  The Company will use its best efforts to prevent the issuance of any such stop order or of any order preventing or suspending such use, and if any such order is issued, to obtain as soon as possible the lifting thereof.

(h)                                 The Company agrees that, unless it obtains the prior written consent of the Representative, it will not make any offer relating to the Notes 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 SEC or retained by the Company under Rule 433 of the Act; provided that the prior written consent of the Representative shall be deemed to have been given in respect of the free writing prospectuses included in Schedule I hereto.  Any such free writing prospectus consented to by the Representative is hereinafter referred to as a “Permitted Free Writing Prospectus.”  The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) 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 SEC, legending and record keeping.

(k)                                  During the course of the distribution of the Notes, the Company will not, and the Company shall cause its officers and directors not to, (i) take, directly or indirectly, any action designed to, or that could reasonably be expected to, cause or result in stabilization or manipulation of the price of the Notes or (ii) sell, bid for, purchase or pay anyone any compensation for soliciting purchases of, the Notes.

(l)                                     During a period of 15 days from the date of this Agreement, the Company will not, without the Representative’s prior written consent, directly or indirectly, sell, offer to sell, grant any option for the sale of, or otherwise dispose of, any Notes or any security convertible into or exchangeable into or exercisable for the Notes or any debt securities substantially similar to the Notes (except for the Notes issued pursuant to this Agreement).

(m)                               The Company shall, at its sole cost and expense, supply and deliver to the Representative and the Underwriters’ counsel, within a reasonable period from the Closing Date transaction binders in such number and in such form as the Representative reasonably requests.

(c)                                  If any action, inquiry, investigation or proceeding is brought against any person in respect of which indemnification may be sought pursuant to Section 8(a) or (b) hereof, such person (hereinafter called the “indemnified party”) shall, promptly after notification of, or receipt of service of process for, such action, inquiry, investigation or proceeding, notify in writing the party or parties against whom indemnification is to be sought (hereinafter called the “indemnifying party”) of the institution of such action, inquiry, investigation or proceeding.  The indemnifying party, upon the request of the indemnified party, shall assume the defense of such action, inquiry, investigation or proceeding, including, without limitation, the employment of counsel (reasonably satisfactory to such indemnified party) and payment of expenses.  No indemnification provided for in this Section 8 shall be available to any indemnified party who shall fail to give such notice if the indemnifying party does not have knowledge of such action, inquiry, investigation or proceeding to the extent that such indemnifying party

18

has been materially prejudiced by the failure to give such notice, but the omission to so notify the indemnifying party shall not relieve the indemnifying party otherwise than under this Section 8.  Such indemnified party shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action or if the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to be in charge of the defense of such action, inquiry, investigation or proceeding, or if such indemnified party or parties shall have been advised by counsel that there may be a conflict between the positions of the indemnifying party or parties and of the indemnified party or parties or that there may be legal defenses available to such indemnified party or parties different from or in addition to those available to the indemnifying party or parties, in any of which events the indemnified party or parties shall be entitled to select counsel to conduct the defense to the extent determined by such counsel to be necessary to protect the interests of the indemnified party or parties, and the reasonable fees and expenses of such counsel shall be borne by the indemnifying party.  The indemnifying party shall be responsible for the fees and disbursements of only one such counsel so engaged by the indemnified party or parties.  Expenses covered by the indemnification in this Section 8, shall be paid by the indemnifying party as they are incurred by the indemnified party.  In the event that it is determined that the indemnified party was not entitled to receive payments for expenses pursuant to this Section 8, the indemnified party shall return all sums that have been paid pursuant hereto.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 any claims that are the subject matter of such action.  Anything in this Section 8 to the contrary notwithstanding an indemnifying party shall not be liable for any settlement of a claim effected without its written consent, which consent shall not be unreasonably withheld.

(d)                                 If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or (b) hereof in respect of any losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to therein, except by reason of the failure to give notice as required in Section 8(c) hereof (provided that the indemnifying party does not have knowledge of the action, inquiry, investigation or proceeding and to the extent such party has been materially prejudiced by the failure to give such notice), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof 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 from the offering of the Notes.  If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits 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 which resulted in such losses, liabilities, claims or expenses (or actions, inquiries, investigations or proceedings in respect thereof), 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 (net of fees, discounts and commissions but before deducting expenses) received by the Company bears to the total underwriting fees, 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 on the one hand or the Underwriters

19

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

The Company and the Underwriters agree that it would not be just and equitable if contributions to this Section 8(d) were determined by 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 above in this Section 8(d).  The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 8(d), (i) the provisions of any Agreement Among Underwriters shall govern contribution among Underwriters, (ii) no Underwriter (except as provided in any Agreement Among Underwriters) shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Notes purchased by such Underwriter, and (iii) 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 Section 8(d) to contribute are several in proportion to their individual underwriting obligations and not joint.

9.                                      Representations and Agreements to Survive Delivery.  Except as the context otherwise requires, all representations, warranties and agreements contained in this Agreement shall be deemed to be representations, warranties and agreements at the Closing Date.  All such representations, warranties and agreements of the Underwriters and the Company, including, without limitation, the indemnity and contribution agreements contained in Section 8 hereof and the agreements contained in Sections 4 (with respect to matters to be performed after the Closing Date), 6, 10 and 11 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriters or any controlling person, and shall survive delivery of the Notes and termination of this Agreement, whether before or after the Closing Date.

10.                               Effective Time of This Agreement and Termination Hereof.

(a)                                  This Agreement shall become effective when the parties hereto have executed and delivered this Agreement.

(b)                                 The Representative shall have the right to terminate this Agreement at any time prior to the Closing Date as provided in Sections 7 and 11 or if any of the following have occurred:  (i) since the respective dates as of which information is given in the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the Business Conditions of the Company, whether or not arising in the ordinary course of business, that would, in the Representative’s opinion, make the offering or delivery of the Notes impracticable; (ii) any outbreak or escalation of hostilities or other national or international calamity or crisis or change in economic, political or financial market conditions if the effect on the financial markets of the United States of such outbreak, calamity, crisis or change would, in the Representative’s reasonable opinion, make the offering or delivery of the Notes impracticable; (iii) any suspension or limitation of trading generally in securities on the NYSE or any setting of minimum prices for trading (other than ordinary course limitations on hours or numbers of days trading) for securities on the NYSE or the promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority that in the Representative’s reasonable opinion make the offering or delivery of the Notes impractical; (iv) declaration of a commercial banking moratorium by the United States, New York or California authorities; or (v) trading in any securities of American States Water or the Company shall have been suspended or halted by the NYSE or the SEC.

20

(c)                                  If the Representative elects to terminate this Agreement as provided in this Section 10, the Representative shall notify the Company hereof promptly by telephone or facsimile, confirmed by letter or otherwise in writing.

11.                               Default by an Underwriter.

(a)                                  If any Underwriter shall default in its obligation to purchase Notes hereunder, and if the Notes with respect to which such default relates do not exceed in the aggregate 10% of the principal amount of Notes that all Underwriters have agreed to purchase on the Closing Date, then the Representative may make arrangements satisfactory to the Company for the purchase of such Notes by other persons, including the non-defaulting Underwriter, but if no such arrangements are made by the Closing Date, such Notes to which the default relates shall be purchased by the non-defaulting Underwriter (in addition to the principal amount of Notes it is obligated to purchase pursuant to Section 2 hereof).

(b)                                 If such default relates to more than 10% of the Notes, the Representative may in its discretion arrange for another party or parties (including a non-defaulting Underwriter) to purchase such Notes to which such default relates, on the terms contained herein.  In the event that the Representative does not arrange for the purchase of the Notes to which a default relates as provided in this Section 11, this Agreement may be terminated by the Representative or by the Company without liability on the part of the non-defaulting Underwriter (except as provided in Section 8 hereof) or the Company (except as provided in Sections 6 and 8 hereof).  Nothing herein shall relieve a defaulting Underwriter of its obligations hereunder, including but not limited to its liability, if any, to the other Underwriter and to the Company for damages occasioned by its default hereunder.

(c)                                  If the Notes to which the default relates are to be purchased by the non-defaulting Underwriter, or are to be purchased by another party or parties, the Representative or the Company shall have the right to postpone the Closing Date for a reasonable period but not in any event exceeding seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment to the Registration Statement or supplement to the Prospectus that in the opinion of counsel for the Underwriters may thereby be made necessary.  The terms “Underwriters” and “Underwriter” as used in this Agreement shall include any party substituted under this Section 11 with like effect as if it had originally been a party to this Agreement with respect to such Notes.

12.                               Information Furnished by the Underwriters.  The identity of the Underwriters set forth under the first paragraph under the heading “Underwriting,” the concession and reallowance figures appearing in the third paragraph under the heading “Underwriting,” the disclosure with respect to market making activities in the fifth paragraph under the heading “Underwriting,” and the disclosure regarding stabilization in the sixth and seventh paragraphs under the heading “Underwriting” constitute the only written information furnished by reference or on behalf of any of the Underwriters in the Prospectus referred to in Sections 1(c), 1(d) and 1(e) and 8 hereof.

13.                               Notice.  All communications hereunder, except as herein otherwise specifically provided, shall be in writing and, if sent to any Underwriter, shall be mailed, delivered, telexed, and confirmed to Wells Fargo Securities, LLC, One Wells Fargo Center, 301 S.

14.                               Parties.  This Agreement shall inure solely to the benefit of, and shall be binding upon, the several Underwriters, the Company and the controlling persons, directors and officers of each, and their respective successors, assigns, heirs and legal representatives, and no other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Agreement or any provision herein contained.  The terms “successors” and “assigns” shall not include any purchaser of the Notes merely because of such purchase.

15.                               Counterparts.  This Agreement may be executed in one or more counterparts (including by means of any standard form of communication) and all such counterparts will constitute one and the same instrument.

16.                               Construction.  This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to agreements made and performed entirely within such state.

17.                               Amendments or Waivers.  No amendment or waiver of any provision of this Agreement, and no consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties thereto.

18.                               Partial Unenforceability.  The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof, provided that minor changes (and only minor changes) can be made so as to make all provisions of this Agreement valid and enforceable.

19.                               Consent to Jurisdiction.  Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby must be instituted in the federal courts of the United States of America or the state courts in the Borough of Manhattan in each case located in the City of New York, and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding.  Service of any process, summons, notice or document by certified mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court.  The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding brought in any such court that has been brought in an inconvenient forum.

22

The Company acknowledges and agrees that in connection with all aspects of each transaction contemplated by this Agreement, the Company, on the one hand, and the Underwriters, on the other hand, have an arms-length business relationship that creates no fiduciary duty on the part of any Underwriter and each expressly disclaims any fiduciary relationship.
