Dear Sirs:

Placer Sierra Bancshares, a California corporation (the “Company”), and California Community Financial Institutions Fund Limited Partnership, a California limited partnership (the “Selling Shareholder”), confirm their respective agreements with each of the Underwriters listed on Schedule II hereto (collectively, the “Underwriters”), for whom Friedman, Billings, Ramsey & Co., Inc. is acting as representative (in such capacity, the “Representative”), with respect to (i) the sale by the Selling Shareholder of 5,000,000 shares (the “Initial Shares”) of Common Stock, no par value per share, of the Company (“Common Stock”), and the purchase by the Underwriters, acting severally and not jointly, of the respective number of shares of Common Stock set forth opposite the names of the Underwriters in Schedule II hereto, and (ii) the grant by the Selling Shareholder to the Underwriters, acting severally and not jointly, of the option described in Section 1(b) hereof to purchase all or any part of 750,000 additional shares of Common Stock to cover over-allotments (the “Option Shares”), if any to be sold by the Selling Shareholder. The Initial Shares to be purchased by the Underwriters and all or any part of the Option Shares subject to the option described in Section 1(b) hereof are hereinafter called, collectively, the “Shares.”

The Company understands that the Underwriters propose to make a public offering of the Shares as soon as the Underwriters deem advisable, subject to applicable law, after this Underwriting Agreement (this “Underwriting Agreement”) has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”), a registration statement on Form S-3 (No. 333-130252), including a related prospectus for the registration of securities, including the Shares, under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder (the “Securities Act Regulations”). The Company has prepared and filed such amendments to the registration statement and such amendments or supplements to the related prospectus as may have been required to the date hereof, and will file such additional amendments or supplements as may hereafter be required. The registration statement has been declared effective under the Securities Act by the Commission. The registration statement, as amended at the time it was

declared effective by the Commission (and, if the Company files a post-effective amendment to such registration statement which becomes effective prior to the Closing Time (as defined below), such registration statement as so amended) and including all information deemed to be a part of the registration statement pursuant to incorporation by reference, Rule 430B of the Securities Act Regulations or otherwise, is hereinafter called the “Registration Statement.” The term “Base Prospectus” means the prospectus dated December 23, 2005 included in the Registration Statement, including all information incorporated by reference therein. The term “Prospectus Supplement” means the prospectus supplement specifically relating to the Shares in the form first filed with the Commission pursuant to Rule 424 under the Securities Act, including all information incorporated by reference therein. The term “Prospectus” means the Base Prospectus together with the Prospectus Supplement. The term “Preliminary Prospectus” means any preliminary form of the Prospectus in the form filed with the Commission pursuant to Rule 424 of the Securities Act Regulations.

The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus.

The term “Disclosure Package” means (i) the Base Prospectus and the Preliminary Prospectus, as most recently amended or supplemented immediately prior to the Initial Sale Time (as defined herein), (ii) the Issuer Free Writing Prospectuses (as defined below), if any, identified in Schedule III hereto, and (iii) any other Free Writing Prospectus (as defined below) that the parties hereto shall hereafter expressly in writing agree to treat as part of the Disclosure Package.

The term “Issuer Free Writing Prospectus” means any issuer free writing prospectus, as defined in Rule 433 of the Securities Act Regulations. The term “Free Writing Prospectus” means any free writing prospectus, as defined in Rule 405 of the Securities Act Regulations.

The Selling Shareholder has executed and delivered a Custody Agreement and an Irrevocable Power of Attorney of the Selling Shareholder in the form attached hereto as Exhibit A (collectively, the “Agreement and Power of Attorney”) pursuant to which the Selling Shareholder has placed the Initial Shares and Option Shares to be sold by it pursuant to this Agreement in custody and appointed the person or persons designated therein with the authority to execute and deliver this Agreement on behalf of the Selling Shareholder and to take certain other actions with respect thereto and hereto.

The Company, the Selling Shareholder and the Underwriters agree as follows:

1. Sale and Purchase:

(a) Initial Shares. Upon the basis of the warranties and representations and other terms and conditions herein set forth, at the purchase price per share of $24.765, the Selling Shareholder agrees to sell to the Underwriters the number of Initial Shares set forth in Schedule I opposite its name, and each Underwriter agrees, severally and not jointly, to purchase from the Selling Shareholder the number of Initial Shares set forth in Schedule II opposite such Underwriter’s name, plus any additional number of Initial Shares which such Underwriter may become obligated to purchase pursuant to the provisions of Section 8 hereof, subject in each

case, to such adjustments among the Underwriters as the Representative in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

(b) Option Shares. In addition, upon the basis of the warranties and representations and other terms and conditions herein set forth, at the purchase price per share set forth in Section 1(a), the Selling Shareholder hereby grants an option to the Underwriters, acting severally and not jointly, to purchase from the Selling Shareholder all or any part of the Option Shares, plus any additional number of Option Shares which such Underwriter may become obligated to purchase pursuant to the provisions of Section 8 hereof. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time until such date only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Shares upon notice by the Representative to the Selling Shareholder (with a copy of the Company) setting forth the number of Option Shares as to which the several Underwriters are then exercising the option and the date of payment and delivery for such Option Shares. Any such time and date of delivery (an “Option Closing Time”) shall be determined by the Representative, but shall not be later than three full business days (or earlier, without the consent of the Company, than two full business days) after the exercise of such option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Shares, the Selling Shareholder will sell such Option Shares to the Underwriters, and each of the Underwriters, acting severally and not jointly, will purchase from the Selling Shareholder that proportion of the total number of Option Shares then being purchased which the number of Initial Shares set forth in Schedule II opposite the name of such Underwriter bears to the total number of Initial Shares, subject in each case to such adjustments among the Underwriters as the Representative in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

2. Payment and Delivery:

(a) Initial Shares. The Initial Shares to be purchased by each Underwriter hereunder, in definitive form, and in such authorized denominations and registered in such names as the Representative may request upon at least forty-eight hours’ prior notice to the Selling Shareholder shall be delivered by or on behalf of the Selling Shareholder to the Representative, including, at the option of the Representative, through the facilities of The Depository Trust Company (“DTC”) for the account of such Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of immediately available funds as follows: (i) $345,000 shall be wire transferred to the account or accounts specified to the Representative by the Company, upon at least forty-eight hours’ prior notice, which amount shall be wire transferred on behalf of the Selling Shareholder to be credited against amounts owed by the Selling Shareholder to the Company pursuant to the Amended and Restated Registration Rights Agreement between the Company and the Selling Shareholder, dated as of May 15, 2004, as amended (the “Registration Rights Agreement”), and (ii) the balance of the purchase price shall be wire transferred to the account or accounts specified to the Representative by the Selling Shareholder, upon at least forty-eight hours’ prior notice. The time and date of such delivery and payment shall be 9:30 a.m., New York City time, on the third (fourth, if pricing occurs after 4:30 p.m., New York City time) business day after the date hereof (unless another time and date shall be agreed to in writing by the Representative and the Selling

Shareholder). The time at which such payment and delivery are actually made is hereinafter sometimes called the “Closing Time.”

(b) Option Shares. Any Option Shares to be purchased by each Underwriter hereunder, in definitive form, and in such authorized denominations and registered in such names as the Representative may request upon at least forty-eight hours’ prior notice to the Selling Shareholder shall be delivered by or on behalf of the Selling Shareholder to the Representative, including, at the option of the Representative, through the facilities of DTC for the account of such Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of immediately available funds to the accounts specified to the Representative by the Selling Shareholder upon at least forty-eight hours’ prior notice.

(iv) subsequent to the respective dates as of which information is given in the Registration Statement, the Prospectus and the Disclosure Package, there has not been (a) any Material Adverse Effect, (b) any transaction that is material to the Company and the Subsidiaries considered as one enterprise, except transactions entered into in the ordinary course of business, (c) any obligation, direct or contingent, that is material to the Company and the Subsidiaries considered as one enterprise, incurred by the Company or the Subsidiaries, except obligations incurred in the ordinary course of business, (d) any change in the capital stock or outstanding long-term indebtedness of the Company or any Subsidiary that is material to the Company and the Subsidiaries considered as one enterprise, (e) any dividend or distribution of any kind declared, paid or made on the capital stock of the Company or any Subsidiary (except any distribution paid or made on any securities of the Trusts), or (f) any loss or damage (whether or not insured) to the property of the Company or any Subsidiary which would result in a Material Adverse Effect.

(m) The Selling Shareholder will, at the Closing Time and on each Option Closing Time, deliver to the Underwriters a certificate, to the effect that:

(i) the representations and warranties of the Selling Shareholder set forth in this Agreement and in the Agreement and Power of Attorney are true and correct (subject to any materiality, knowledge and other qualifications set forth therein) as of such date; and

(ii) the Selling Shareholder has complied in all material respects with all the agreements and has satisfied all the conditions on its part to be performed or satisfied hereunder and under the Agreement and Power of Attorney at or prior to the date thereof.

(n) The Company and the Selling Shareholder, as applicable, shall have furnished to the Underwriters such other documents and certificates as to the accuracy and completeness of any statement in the Registration Statement, the Prospectus and the Disclosure Package, the representations, warranties and statements of the Company contained herein and in the Agreement and Power of Attorney, and the performance by the Company and the Selling Shareholder of their respective covenants contained herein and therein, and the fulfillment of any conditions contained herein or therein, as of the Closing Time or the relevant Date of Delivery, as the Underwriters may reasonably request.

7. Termination:

The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of the Representative, at any time prior to the Closing Time or, with respect to any Option Shares, the relevant Date of Delivery, (i) if any of the conditions specified in Section 6 shall not have been fulfilled when and as required by this Agreement to be fulfilled, or (ii) if there has been since the respective dates as of which information is given in the Registration Statement, the Prospectus or the Disclosure Package, any Material Adverse Effect, or any development involving a prospective Material Adverse Effect, or material change in management of the Company or any Subsidiary, whether or not arising in the ordinary course of business, or (iii) if, after the date hereof, there has occurred any outbreak or escalation of hostilities or other national or international calamity or crisis or adverse change in economic, political or other conditions the effect of which on the financial markets of the United States is such as to make it, in the reasonable judgment of the Representative, impracticable to market the Shares or enforce contracts for the sale of the Shares, or (iv) if trading in any securities of the Company has been suspended by the Commission or by the Nasdaq National Market, or if trading generally on the New York Stock Exchange or on the Nasdaq National Market has been suspended (including an automatic halt in trading pursuant to market-decline triggers, other than those in which solely program trading is temporarily halted), or limitations on prices for trading (other than limitations on hours or numbers of days of trading) have been fixed, or maximum ranges for prices for securities have been required, by such exchange or quotation system or by order of the Commission or any other governmental authority, or (v) any federal or state statute, regulation, rule or order of any court or other governmental authority has been enacted, published, decreed or otherwise promulgated which, in the reasonable opinion of the Representative, materially adversely affects or will materially adversely affect the business or operations of the Company, or (vi) if a banking moratorium (or any action having the same effect

as a banking moratorium) has been declared by either federal or New York authorities, or any action has been taken by any federal, state or local government or agency in respect of its monetary or fiscal affairs, each of which in the reasonable opinion of the Representative, has a material adverse effect on the securities markets in the United States.

If the Representative elects to terminate this Agreement as provided in this Section 7, the Company, the Selling Shareholder and the Underwriters shall be notified promptly by telephone, promptly confirmed by facsimile.

If the sale to the Underwriters of the Shares, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because the Company or the Selling Shareholder shall be unable to comply in all material respects with any of the terms of this Agreement, the Company and the Selling Shareholder shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 5 and 9 hereof) and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

8. Increase in Underwriters’ Commitments:

If any Underwriter shall default at the Closing Time or on the relevant Date of Delivery on its obligation to take up and pay for the Initial Shares or the Option Shares, as applicable, to be purchased by it under this Agreement on such date, the Representative shall have the right, within 36 hours after such default, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Shares which such Underwriter shall have agreed but failed to take up and pay for (the “Defaulted Shares”). Absent the completion of such arrangements within such 36-hour period, (i) if the total number of Defaulted Shares does not exceed 10% of the total number of Shares to be purchased on such date, each non-defaulting Underwriter shall take up and pay for (in addition to the number of Shares which it is otherwise obligated to purchase on such date pursuant to this Agreement) the portion of the total number of Shares agreed to be purchased by the defaulting Underwriter on such date in the proportion that its underwriting obligations hereunder bears to the underwriting obligations of all non-defaulting Underwriters or in such amount as may otherwise be agreed upon by the non-defaulting Underwriters; and (ii) if the total number of Defaulted Shares exceeds 10% of such total, the Representative may terminate this Agreement by notice to the Company, without liability of any party to any other party except that the provisions of Sections 5 and 9 hereof shall at all times be effective and shall survive such termination.

Without relieving any defaulting Underwriter from its obligations hereunder, the Selling Shareholder agrees with the non-defaulting Underwriters that it will not sell any Initial Shares or Option Shares, as applicable, hereunder on such date unless all of the Initial Shares or Option Shares to be purchased on such date are purchased on such date by the non-defaulting Underwriters (or by substituted Underwriters selected by the Representative with the approval of the Company) in accordance with the first paragraph of this Section 8.

If a new Underwriter or Underwriters are substituted for a defaulting Underwriter in accordance with the foregoing provision, the non-defaulting Underwriters shall have the right to postpone the Closing Time or the relevant Date of Delivery for a period not exceeding five

business days in order that any necessary changes in the Registration Statement and Prospectus and other documents may be effected. The term “Underwriter” as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with the same effect as if such substituted Underwriter had originally been named in this Agreement.

9. Indemnity and Contribution by the Company, the Selling Shareholder and the Underwriters:

(a) The Company agrees to indemnify, defend and hold harmless each Underwriter and any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the respective directors, officers, employees and agents of each Underwriter, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or controlling person may incur under the Securities Act, the Exchange Act or otherwise, but only insofar as such loss, expense, liability, damage or claim arises out of or is based upon (A) any breach of any representation, warranty or covenant of the Company contained herein, (B) any failure on the part of the Company to comply with any applicable law, rule or regulation relating to the offering of the securities being made pursuant to the Prospectus, (C) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment or part thereof), any Issuer Free Writing Prospectus that the Company has filed or was required to file with the Commission or the Prospectus (the term Prospectus for the purpose of this Section 9 being deemed to include the Base Prospectus, any Preliminary Prospectus, the Prospectus and the Prospectus as amended or supplemented by the Company), (D) in any application or other document, or any amendment or supplement thereto, executed by the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction (domestic or foreign) in order to qualify the Shares under the securities or blue sky laws thereof or filed with the Commission or any securities association or securities exchange (each an “Application”), (E) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, or necessary to make the statements made therein not misleading, (F) any omission or alleged omission from any such Issuer Free Writing Prospectus, Prospectus or any Application of a material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, (G) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials used in connection with the marketing of the Shares, including, without limitation, slides, videos, films and tape recordings; except insofar as any such loss, expense, liability, damage or claim relating to subparagraphs (C), (D), (E) or (F) above arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in and in conformity with information furnished in writing by the Underwriters through the Representative to the Company expressly for use in such Registration Statement, Prospectus, Issuer Free Writing Prospectus or Application; and with respect to the Preliminary Prospectus or the Prospectus, shall not inure to the benefit of any Underwriter (or any controlling person of such Underwriter) with respect to any person asserting such loss, expense, liability, damage or claim which is the subject hereof if the Prospectus or any supplement thereto prepared with the consent of the Representative and furnished to the Underwriters prior to the Closing Time or the relevant Date of Delivery corrected any such untrue statement or alleged untrue statement or omission or alleged omission of a material fact, and if such Underwriter failed to send or give a copy of such Prospectus or supplement thereto to

such person at or prior to the time written confirmation of the sale of Shares was given to such person; provided that the Underwriter will be entitled to indemnification as long as it uses its reasonable best efforts to send or give a copy of such Prospectus or supplement thereto to such person at or prior to the time written confirmation of the sale of Shares was given to such person. The indemnity agreement set forth in this Section 9(a) shall be in addition to any liability which the Company may otherwise have.

(b) The Selling Shareholder agrees to indemnify, defend and hold harmless each Underwriter and any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or controlling person may incur under the Securities Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (A) any breach of any representation, warranty or covenant of such Selling Shareholder contained herein or in the Agreement and Power of Attorney, (B) any failure on the part of such Selling Shareholder to comply with any applicable law, rule or regulation relating to the offering of securities being made pursuant to the Prospectus, (C) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment or part thereof), any Issuer Free Writing Prospectus that the Company has filed or was required to file with the Company, or the Prospectus or any Application, (D) any omission or alleged omission to state a material fact required to be stated in any such Registration, or necessary to make the statements made therein or (E) any omission or alleged omission from any such Issuer Free Writing Prospectus, Prospectus or any Application of a material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading; but only insofar as any such loss, expense, liability, damage or claim relating to subparagraphs (C), (D) or (E) arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in and in conformity with information furnished in writing by the Selling Shareholder to the Company expressly for use in such Registration Statement, Prospectus, Issuer Free Writing Prospectus or Application; provided, however, that the indemnity agreement contained in this subsection (b) shall not require the Selling Shareholder to reimburse the Underwriters for in excess of the net sale price of the Shares sold by the Selling Shareholder pursuant to this Agreement. The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that the Selling Shareholder may otherwise have.

If any action is brought against an Underwriter, controlling person or other indemnified party in respect of which indemnity may be sought against the Company or the Selling Shareholder pursuant to paragraphs (a) or (b) of this Section 9, such indemnified party (or parties) shall promptly notify the indemnifying party in writing of the institution of such action, and the indemnifying party (or, if such action is brought against both the Company and the Selling Shareholder, the Company) shall assume the defense of such action including the employment of counsel and payment of expenses (with counsel reasonably satisfactory to the indemnified party); provided, however, that any failure or delay to so notify the indemnifying party will not relieve such party of any obligation hereunder, except to the extent that its ability to defend is actually impaired by such failure or delay. The indemnified party or parties 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 party or parties unless (i) the employment of such

counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, or (ii) the indemnifying party shall not have employed counsel to have charge of the defense of such action within a reasonable time or the indemnified party or parties shall have reasonably concluded (based on the written advice of outside counsel) that there may be defenses available to it or them which (1) are different from or additional to those available to the indemnifying party and (2) in the opinion of such outside counsel present an actual or potential conflict for counsel representing the indemnifying party and the indemnified party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), or (iii) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the action, suit or proceeding, in any of which events such reasonable fees and expenses shall be borne by the indemnifying party and paid as incurred (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate firm of attorneys in any one action or series of related actions in the same jurisdiction (other than local counsel in any such jurisdiction) representing the indemnified parties who are parties to such action unless the defense of one indemnified party is unique or separate from that of another indemnified party subject to the same claim or action). Anything in this paragraph to the contrary notwithstanding, the indemnifying party or parties shall not be liable (i) for any settlement of any such claim or action effected without its prior written consent, unless such settlement (x) includes an unconditional release of the indemnifying party or parties from any and all liabilities arising from such claim or action and (y) does not include a statement as to or an admission of fault, culpability or failure to act, of, by or on behalf of such indemnifying party or parties, or (ii) to the extent that any loss, claim, damage or liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted primarily from the indemnified party’s willful misconduct or gross negligence.

(c) Each Underwriter agrees, severally and not jointly, to indemnify, defend and hold harmless the Company, the Selling Shareholder, the Company’s directors, the Company’s officers that signed the Registration Statement and any person who controls the Company or the Selling Shareholder (including, without limitation, the general partner of the Selling Shareholder) within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, the Company, the Selling Shareholder or any such person may incur under the Securities Act, the Exchange Act or otherwise, but only insofar as such loss, expense, liability, damage or claim arises out of or is based upon (a) any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by such Underwriter through the Representative to the Company expressly for use in the Registration Statement (or any amendment or part thereof), any Issuer Free Writing Prospectus that the Company has filed or was required to file with the Commission, the Prospectus or any Application, or (b) any omission or alleged omission to state a material fact in connection with such information required to be stated either in such Registration Statement, or necessary to make such information not misleading, or (c) any omission or alleged omission from any such Issuer Free Writing Prospectus, Prospectus or any Application of a material fact necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading. The last paragraph of text on the front cover page immediately before the names of the Underwriters,

the names of the Underwriters on the front and back cover pages, the names and corresponding Share amounts set forth in the table under the caption “Underwriting,” the fourth paragraph of text on page S-13 under the caption “Underwriting” and the first, second, third, fourth, fifth and seventh paragraphs of text on page S-14 under the caption “Underwriting”) in the Preliminary Prospectus and (the corresponding paragraphs of) the Prospectus, constitute the only information furnished to or by or on behalf of any Underwriter through the Representative to the Company for purposes of Section 3(m) and this Section 9. The indemnity agreement set forth in this Section 9(c) shall be in addition to any liabilities that the Underwriters may otherwise have.

If any action is brought against the Company, the Selling Shareholder, controlling person or other indemnified party in respect of which indemnity may be sought against any Underwriter pursuant to this Section 9(c), the Company, the Selling Shareholder or such person or party shall promptly notify the Representative in writing of the institution of such action and the Representative, on behalf of the Underwriters, shall assume the defense of such action, including the employment of counsel and payment of expenses; provided, however, that any failure or delay to so notify the indemnifying party will not relieve such party of any obligation hereunder, except to the extent that its ability to defend is actually impaired by such failure or delay.

The Company, the Selling Shareholder or such person or party shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company, the Selling Shareholder or such person or party unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, or (ii) the indemnifying party shall not have employed counsel to have charge of the defense of such action within a reasonable time or the indemnified party or parties shall have reasonably concluded (based on the written advice of outside counsel) that there may be defenses available to it or them which (1) are different from or additional to those available to the indemnifying party and (2) in the opinion of such outside counsel present an actual or potential conflict for counsel representing the indemnifying party and the indemnified party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), or (iii) the indemnifying party has not in fact employed counsel reasonably satisfactory to the indemnified party to assume the defense of such action within a reasonable time after receiving notice of the action, suit or proceeding, in any of which events such reasonable fees and expenses shall be borne by the indemnifying party and paid as incurred (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate firm of attorneys in any one action or series of related actions in the same jurisdiction (other than local counsel in any such jurisdiction) representing the indemnified parties who are parties to such action unless the defense of one indemnified party is unique or separate from that of another indemnified party subject to the same claim or action). Anything in this paragraph to the contrary notwithstanding, no Underwriter shall be liable for any settlement of any such claim or action effected without the prior written consent of the Representative, unless such settlement (x) includes an unconditional release of the Underwriters from any and all liabilities arising from such claim or action and (y) does not include a statement as to or an admission of fault, culpability or failure to act, of, by or on behalf of such Underwriters.

(d) If the indemnification provided for in this Section 9 is unavailable or insufficient to hold harmless an indemnified party under paragraphs (a), (b), (c) and (d) of this

Section 9 in respect of any losses, expenses, liabilities, damages or claims referred to therein, then each applicable 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, expenses, liabilities, damages or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Selling Shareholder and the Underwriters from the offering of the Shares or (ii) if (but only 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, of the Selling Shareholder and of the Underwriters in connection with the statements or omissions which resulted in such losses, expenses, liabilities, damages or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Selling Shareholder and the Underwriters shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company or the Selling Shareholder, as applicable, bear to the underwriting discounts and commissions received by the Underwriters. The relative fault of the Company, of the Selling Shareholder and of the Underwriters shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company, by the Selling Shareholder or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any claim or action.

(e) The Company, the Selling Shareholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 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 which does not take account of the equitable considerations referred to in subsection (d)(i) and, if applicable (ii), above. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter and the Selling Shareholder shall not be required to contribute any amount in excess of the net sale price of the Shares sold by the Selling Shareholder pursuant to this Agreement. 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 pursuant to this Section 9 are several (in proportion to their respective underwriting commitments) and not joint. For purposes of this paragraph (e), each person who controls an Underwriter or who is a director, officer, employee or agent of an Underwriter, and is entitled to indemnification under paragraph (a) or (b) of this Section 9, shall have the same rights to contribution as such Underwriter, and each person who controls the Company or the Selling Shareholder, or who is a director, officer, employee or agent of the Company or the Selling Shareholder, and is entitled to indemnification under paragraph (c) of this Section 9, shall have the same rights to contribution as the Company or the Selling Shareholder, as the case may be.

10. Survival:

The indemnity and contribution agreements contained in Section 9 and the covenants, warranties and representations of the Company and the Selling Shareholder contained in Sections 3, 4 and 5 of this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, or any person who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or the respective directors, officers, employees or agents of each Underwriter, or by or on behalf of the Company or the Selling Shareholder, or any person who controls the Company or the Selling Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or the respective directors, officers, employees or agents of the Company and the Selling Shareholder, and shall survive any termination of this Agreement or the sale and delivery of the Shares. The Company, each Selling Shareholder and each Underwriter agree promptly to notify the others of the commencement of any litigation or proceeding against it (or any of its respective directors, officers, employees or agents), in connection with the sale and delivery of the Shares, or in connection with the Registration Statement or Prospectus.

11. Notices:

Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered to Friedman, Billings, Ramsey & Co., Inc., 1001 19th Street North, Arlington, Virginia 22209, Attention: Syndicate Department; or if to the Company shall be sufficient in all respects if delivered to Placer Sierra Bancshares, 525 J Street, Sacramento, California 95814, Attention: Chairman of the Board and Chief Executive Officer, with a copy to: Manatt, Phelps & Phillips LLP, 11355 West Olympic Blvd., Los Angeles, California 90064, Attention: John C.

Plevin, Esq.

12. Governing Law; Headings:

THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES. The section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

13. Parties at Interest:

The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Company, the Selling Shareholder and the controlling persons, directors and officers referred to in Sections 9 and 10 hereof, and their respective successors, assigns, executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

14. Counterparts and Facsimile Signatures:

This Agreement may be signed by the parties in counterparts which together shall constitute one and the same agreement among the parties. A facsimile signature shall constitute an original signature for all purposes.

15. Entire Agreement:

This Agreement (including the exhibits and scheduled hereto and documents delivered pursuant hereto) is intended by the parties to and does constitute the entire agreement between the Company, the Selling Shareholder and the Underwriters, with respect to the transactions contemplated by this Agreement; provided, that the parties agree that this Underwriting Agreement does not supersede or terminate the provisions of the Registration Rights Agreement between the Company and the Selling Shareholder and the Registration Rights Agreement remains in full force and effect.

16. Duties:

Nothing in this Agreement shall be deemed to create a partnership, joint venture or agency relationship between the parties. The Underwriters undertake to perform such duties and obligations only as expressly set forth herein. Such duties and obligations of the Underwriters with respect to the Shares shall be determined solely by the express provisions of this Agreement, and the Underwriters shall not be liable except for the performance of such duties and obligations with respect to the Shares as are specifically set forth in this Agreement. Each of the Company and the Selling Shareholder acknowledges and agrees that: (i) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the public offering price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Selling Shareholder, on the one hand, and the several Underwriters, on the other hand, and the Selling Shareholder is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company, the Selling Shareholder or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company or the Selling Shareholder with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Selling Shareholder on other matters); and (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Selling Shareholder and that the several Underwriters have no obligation to disclose any of such interests. The Company and the Selling Shareholder acknowledges that the Underwriters disclaim any implied duties (including any fiduciary duty), covenants or obligations arising from the Underwriters’ performance of the duties and obligations expressly set forth herein. The Company and the Selling Shareholder hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Selling Shareholder may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

If the foregoing correctly sets forth the understanding among the Company, the Selling Shareholder and the Underwriters, please so indicate in the space provided below for the purpose, whereupon this Agreement shall constitute a binding agreement among the Company, the Selling Shareholder and the Underwriters.

The undersigned CALIFORNIA COMMUNITY FINANCIAL INSTITUTIONS FUND LIMITED PARTNERSHIP, a California limited partnership and shareholder (“Selling Shareholder”) of Placer Sierra Bancshares, a California corporation (the “Company”), understands that it will sell Common Stock, no par value (“Common Stock”), of the Company to certain underwriters (the “Underwriters”) represented by Friedman Billings Ramsey & Co., Inc.

Dear Ladies and Gentlemen:

There are delivered to you herewith one or more certificates, in negotiable and proper deliverable form (with the signature guaranteed by a bank, trust company, broker, dealer, municipal securities dealer, government securities dealer or broker, credit union, a national securities exchange, registered securities association or clearing agency, or a savings institution that is a participant in a Securities Transfer Association recognized program or by a Medallion Signature Guarantor) or accompanied by a duly executed stock power or powers, in blank, bearing the signature of the undersigned so guaranteed), representing no less than the number of issued and outstanding shares of Common Stock, no par value (the “Common Stock”), of Placer Sierra Bancshares, a California corporation (the “Company”), set forth opposite the signature of the undersigned at the end of this letter. The undersigned agrees to deliver to the Attorneys (as defined herein) or to you such additional documentation as the Attorneys, or any one of them, or the Company or Friedman Billings Ramsey & Co., Inc., as representative of the several underwriters, or you or any of their respective counsel may reasonably request to effectuate or confirm compliance with any of the provisions hereof or of the Underwriting Agreement (as defined herein), all of the foregoing to be in form and substance reasonably satisfactory in all respects to the Attorneys and you. The certificates for the Common Stock are to be held by you as Custodian for the account of the undersigned and are to be disposed of by you in accordance with this Custody Agreement.

Concurrently with the execution and delivery of this Custody Agreement, the undersigned has executed and delivered an irrevocable power of attorney (“Power of Attorney”) to David Hooston and Randall E. Reynoso (individually, an “Attorney” and collectively, the “Attorneys”), authorizing the Attorneys, or any one of them, to sell from the number of shares of Common Stock represented by the certificates deposited with you hereunder, up to that number of shares of Common Stock set forth opposite the signature of the undersigned at the end of this letter (including any Option Shares (as defined in the Underwriting Agreement)), or such lesser number as the Attorneys, or any one of them, may determine, and for that purpose to enter into and perform an underwriting agreement (the “Underwriting Agreement”), among the Company, and the undersigned (the “Selling Shareholder”), and certain underwriters (the “Underwriters”) represented by Friedman, Billings, Ramsey & Co., Inc. (“FBR”) (the “Representative”).

In addition the undersigned has completed and signed the attached Substitute Form W-9.

You are authorized and directed (a) to hold the certificates deposited with you hereunder in your custody and (b) at each Closing Time specified in the Underwriting Agreement at which the undersigned is selling any shares of Common Stock (each such time is hereinafter sometimes called the “Closing Time”) you shall take all necessary action (i) to cause the Common Stock to be transferred on the books of the Company into such names as the Attorneys, or any one of them, or the Underwriter shall have instructed you and to exchange the certificates representing such Common Stock for new certificates for such Common

A-5

Stock registered in such names and in such denominations as the Attorneys, or any one of them, or FBR shall have instructed you, and (ii) to deliver such new certificates to FBR for the account of the Underwriters, against payment of the purchase price for such Common Stock, and give receipt for such payment, (iii) pay such taxes, as you may be instructed to pay by the Attorneys, or any one of them, and, if instructed by an Attorney to do so, remit to the undersigned the balance, after deducting such taxes, of the amount received by you as payment for such Common Stock, and (iv) furnish to the undersigned a Form 1099 on or before the next following January 31. With such remittance you shall also deliver or cause to be delivered to the undersigned new certificates (which may bear appropriate legends) representing the number of shares of Common Stock deposited hereunder (if any) that are in excess of the number of shares of Common Stock sold (and to be sold at any subsequent Closing Time) by the undersigned to the Underwriters.

If the Underwriting Agreement shall not be entered into and the transactions contemplated thereby shall not be consummated prior to February 28, 2006 then promptly after that date, you are to return to the undersigned the certificates for the Common Stock deposited with you hereunder.

Under the terms of the Power of Attorney, the authority conferred thereby is granted, made and conferred subject to and in consideration of the interests of the Underwriters and, prior to February 28, 2006, is irrevocable and not subject to termination by the undersigned or by operation of law, and the obligations of the undersigned under the Underwriting Agreement are similarly not subject to termination and shall remain in full force and effect until such date. Accordingly, the certificates deposited with you hereunder and this Custody Agreement and your authority hereunder are subject to the interests of the Underwriters, and this Custody Agreement and your authority hereunder are irrevocable and are not subject to termination, except as set forth in the preceding paragraph, by the undersigned or by operation of law, whether by the death or incapacity of the undersigned (if the undersigned is an individual), by the death or incapacity of any trustee or executor or the termination of any trust or estate (if the undersigned is a trust or an estate), or by the dissolution or liquidation of any corporation or partnership (if the undersigned is a corporation or partnership) or the occurrence of any other event. If any event referred to in the preceding sentence should occur before the delivery of the Common Stock to be sold by the undersigned under the Underwriting Agreement, certificates for such Common Stock shall, except as specifically provided in the Underwriting Agreement, be delivered by you on behalf of the undersigned in accordance with the terms and conditions of the Underwriting Agreement and this Custody Agreement, and action taken by you pursuant to this Custody Agreement shall be as valid as if such event had not occurred, whether or not you or the Attorneys, or any one of them, shall have received notice of such event.

Until payment of the purchase price pursuant to the Underwriting Agreement has been made to the undersigned by or for the account of the Underwriters, the undersigned shall remain the owner of the Common Stock delivered to you hereunder and shall have the right to vote such Common Stock and all other Common Stock, if any, represented by the certificates deposited with you hereunder and to receive any and all dividends and distributions thereon.

You shall be entitled to act and rely upon any statement, request, notice or instruction respecting this Custody Agreement given to you by the Attorneys, or any one of them; provided, however, that you shall not be entitled to act on any statement or notice to you with respect to a Closing Time under the Underwriting Agreement, or with respect to the termination of the Underwriting Agreement, or advising that the Underwriting Agreement shall not have been executed and delivered, unless such statement or notice shall have been confirmed in writing to you by FBR.

It is understood that you assume no responsibility or liability to any person other than to deal with the certificates deposited with you hereunder and to deliver to the undersigned a Form 1099 in accordance with the provisions of this Custody Agreement, and the undersigned agrees to indemnify and hold you harmless with respect to anything done by you in good faith in accordance with the foregoing instructions.

This Custody Agreement constitutes a representation and warranty by the undersigned that the undersigned has, and at each Closing Time will have (i) good and marketable title to the Common Stock to be sold on each such Closing Time pursuant to the Underwriting Agreement, free and clear of all liens,

A-6

encumbrances and claims whatsoever (other than pursuant to the Underwriting Agreement, the Power of Attorney and this Custody Agreement), (ii) full legal right and power and all authorizations and approvals required by law to sell, transfer and deliver such Common Stock to the Underwriters under the Underwriting Agreement, and upon delivery of and payment for such Common Stock under the Underwriting Agreement, the undersigned will deliver good and marketable title thereto to the Underwriters, free and clear of any pledge, lien, encumbrance, security interest or other claim (other than any pledge, lien, encumbrance, security interest or other claim created by any of the Underwriters or against any of the Underwriters by any third party); and (iii) full legal right and power and all authorizations and approvals required by law to enter into this Custody Agreement, the Power of Attorney and the Underwriting Agreement and to carry out all the applicable terms and provisions hereof and thereof, and this Custody Agreement, the Power of Attorney and the Underwriting Agreement are, and at all times through each Closing Time will be, valid and binding obligations of the undersigned enforceable in accordance with its terms, except as such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, liquidation or similar laws relating to or affecting the enforcement of creditors’ rights and remedies, (B) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including without limitation (i) the possible unavailability of specific performance, injunctive relief or any other equitable remedy and (ii) concepts of materiality, reasonableness, good faith and fair dealing, and (C) public policy.

All material information with respect to the undersigned contained in the Registration Statement (as defined in the Underwriting Agreement), the Prospectus (as defined in the Underwriting Agreement) and the Disclosure Package (as defined in the Underwriting Agreement) (as amended or supplemented, if the Company shall have filed with the Securities and Exchange Commission any amendment or supplement thereto) and made in reliance upon and in conformity with information furnished in writing by the undersigned to the Company expressly for use in the Registration Statement, the Prospectus and the Disclosure Package contains and will contain all statements of material fact required to be stated therein in accordance with the Securities Act of 1933, as amended, and the rules and regulations thereunder, and does not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading.

If, at any time prior to the date on which the distribution of the Common Stock as contemplated in the Underwriting Agreement and in the Prospectus and the Disclosure Package has been completed, as determined by FBR, the undersigned has knowledge of the occurrence of any event as a result of which the Registration Statement, as then amended, would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading or the Prospectus or the Disclosure Package, in each case as then amended or supplemented, would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the undersigned will promptly notify the Company, FBR and the Attorneys.

The undersigned has not taken and will not take, directly or indirectly, any action designed to or that 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 shares of Common Stock being sold pursuant to the Underwriting Agreement.

The foregoing representations, warranties and agreements, are made for the benefit of, and may be relied upon by, the Attorneys, the Company, the Underwriters, the Custodian and the representative, agents and counsel of each of the foregoing.

This Custody Agreement shall be governed by, and construed in accordance with, the laws of the State of California, without regard to principles of conflicts of laws.

Friedman, Billings, Ramsey & Company, Inc.

1001 19th Street North, 10th Floor

Arlington, Virginia 22209

Dear Sirs:

The undersigned understands that Friedman, Billings, Ramsey & Company, Inc. (the “Representative”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”), as representative of several underwriters (the “Underwriters”), with Placer Sierra Bancshares, a California corporation (the “Company”), providing for the public offering (the “Public Offering”) by the Underwriters of shares of common stock of the Company (the “Common Stock”).

To induce the Underwriters to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representative on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending on the 60-day anniversary of the date of the final prospectus relating to the Public Offering (the “Prospectus”), (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, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for any shares of Common Stock (whether such shares or any such securities are now owned by the undersigned or are hereafter acquired), or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above it is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (3) announce publicly an intention to do any of the same.

The foregoing restrictions shall not apply to (i) a bona fide gift or gifts, provided that the donee or donees agree to be bound in writing by the restrictions set forth herein, (ii) transfers to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) transfers to an affiliate or any equity holder (including but not limited to any limited partner) of the undersigned, provided that such affiliate or equity holder agrees to be bound in writing by the restrictions set forth herein, (iv) transfers of such shares or securities occurring by operation of law, such as rules of intestate succession or statutes governing the effect of a merger, provided that the transferee executes an agreement stating that the transferee is receiving and holding the shares subject to the provisions of this Lock-up letter, (v) any transfers of any shares of Common Stock to the Underwriters pursuant to the Underwriting Agreement, (vi) the exercise of options or warrants held by the undersigned to purchase shares of Common Stock or the conversion or exchange of any convertible or exchangeable securities held by the undersigned which are convertible or exchangeable into Common Stock, provided that all such shares of Common Stock acquired will be subject to the provisions of this Lock-up letter or (vii) any transactions in

B-1

the Common Stock effected by the undersigned with the prior written consent of the Representative on behalf of the Underwriters. For purposes of this Lock-Up letter, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned now has and, except as contemplated by clause (i), (ii), (iii), (iv) or (v) above, for the duration of the Lock-Up letter will have good and marketable title to the undersigned’s shares of Common Stock, free and clear of all liens, encumbrances, and claims whatsoever, except with respect to any liens, encumbrances and claims that were in existence on the date hereof. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s common stock, except in compliance with this Lock-Up letter. In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up letter.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to the Underwriting Agreement, the terms of which are subject to agreement between the Company and the Representative. The terms of this Lock-Up letter shall expire in the event that the Public Offering is not consummated on or before February 28, 2006.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up letter and that this Lock-Up letter constitutes the valid and binding obligation of the undersigned, enforceable in accordance with its terms. Upon request, the undersigned will execute any additional documents necessary in connection with enforcement hereof. Any obligations of the undersigned shall be binding upon the successors and assigns of the undersigned from the date first above written.

This Lock-Up letter shall be governed by and construed in accordance with the laws of the State of New York. Delivery of a signed copy of this letter by telecopier or facsimile transmission shall be effective as delivery of the original hereof.


Very truly yours,
