Item 5.  Other Events.
- ----------------------

     (a)  On July 14, 2003, Sterling Financial Corporation, a Washington
corporation ("Sterling"), entered into an Agreement and Plan of Merger (the
"Merger Agreement") with Klamath First Bancorp, Inc., an Oregon corporation
("Klamath").  Under the terms of the Merger Agreement, Klamath will be merged
with and into Sterling with Sterling being the surviving corporation in the
merger.  The Merger Agreement also provides for the merger of Klamath's
financial institution subsidiary, Klamath First Federal Savings and Loan
Association, with and into Sterling's financial institution subsidiary,
Sterling Savings Bank, with Sterling Savings Bank being the surviving
institution.

     Under the terms of the Merger Agreement, which has been unanimously
approved by the Boards of Directors of both companies, each share of Klamath
common stock will be converted into 0.77 shares of Sterling common stock
subject to certain conditions.  Based upon the closing price for Sterling on
July 14 of $26.55 per share, the consideration is equivalent to $20.44 per
share of Klamath common stock.  The transaction, which is valued at
approximately $147 million, is expected to close in the first quarter of 2004,
pending shareholder and regulatory approval.  The parties have agreed to pay
termination fees in the event the Merger Agreement is terminated under certain
conditions.  The exchange of shares is expected to be tax-free to the Klamath
shareholders.

     For additional information regarding the terms of the proposed
transaction, reference is made to the Merger Agreement and the press release
jointly issued by Sterling and Klamath announcing the Merger, which are
attached hereto as Exhibits 2 and 99.1, respectively, and incorporated herein
by reference.

                          AGREEMENT AND PLAN OF MERGER

     This AGREEMENT AND PLAN OF MERGER, dated as of July 14, 2003 (this
"Agreement"), is entered into by and between Sterling Financial Corporation, a
Washington corporation ("Sterling") and Klamath First Bancorp, Inc., an Oregon
corporation ("Klamath").

     WHEREAS, the Boards of Directors of Sterling and Klamath have determined
that it is in the best interests of their respective companies and
shareholders to consummate the business combination transaction provided for
herein in which Klamath will, subject to the terms and conditions set forth
herein, merge with and into Sterling, with Sterling being the surviving
corporation in such merger (the "Merger");

     WHEREAS, prior to the consummation of the Merger, Sterling and Klamath
will respectively cause Sterling Savings Bank, a Washington State-chartered
savings and loan association and wholly-owned subsidiary of Sterling
("Sterling Savings Bank"), and Klamath First Federal Savings and Loan
Association, a federal stock savings and loan association and wholly-owned
subsidiary of Klamath ("Klamath First Federal"), to enter into a merger
agreement, in the form attached hereto as Exhibit A (the "Institution Merger
Agreement"), providing for the merger (the "Institution Merger") of Klamath
First Federal with and into Sterling Savings Bank, with Sterling Savings Bank,
a Washington State-chartered savings and loan association, being the
"Surviving Institution" of the Institution Merger;

     WHEREAS, the Merger is intended to be treated as a "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"); and

     WHEREAS, the parties desire to make certain representations, warranties
and agreements in connection with the Merger and also to prescribe certain
conditions to the Merger;

     NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements contained herein, and intending to
be legally bound hereby, the parties agree as follows:

                                   ARTICLE I
                                   THE MERGER

     1.1   THE MERGER.

     Subject to the terms and conditions of this Agreement, at the Effective
Time (as defined in Section 1.2 hereof), Klamath shall merge with and into
Sterling, with Sterling being the surviving corporation (hereinafter sometimes
called the "Surviving Corporation") in the Merger.  Upon consummation of the
Merger, the corporate existence of Klamath shall cease and the Surviving
Corporation shall continue to exist as a Washington corporation.

     1.2   EFFECTIVE TIME.

     The Merger shall become effective on the Closing Date (as defined in
Section 9.1 hereof), as set forth in the articles of merger (the "Oregon
Articles of Merger") in the form attached as Exhibit C(1) hereto which shall
be filed with the Secretary of State of the State of Oregon on the Closing
Date and the articles of merger (the "Washington Articles of Merger") in the
form attached as Exhibit C(2) hereto which shall be filed with the Secretary
of State of the State of Washington on the Closing Date.  The term "Effective
Time" shall be the date and time when the Merger becomes effective on the
Closing Date.

     1.3   EFFECTS OF THE MERGER.

     At and after the Effective Time, the Merger shall have the effects set
forth in Section 60.497 of the Oregon Business Corporation Act (the "OBCA")
and Section 23B.11.060 of the Washington Business Corporation Act (the
"WBCA").

                                      1





     1.4   CONVERSION OF KLAMATH COMMON STOCK.

          (a)  At the Effective Time, by virtue of the Merger and without any
     action on the part of the holder of any shares of Klamath common stock,
     each share of Klamath common stock, par value $.01 per share (the
     "Klamath Common Stock") that is issued and outstanding immediately prior
     to the Effective Time will be converted into 0.77 shares (the "Exchange
     Ratio") of the common stock, par value $1.00 per share, of Sterling (the
     "Sterling Common Stock").

          (b)  All of the shares of Klamath Common Stock converted into
     Sterling Common Stock pursuant to this Article I shall no longer be
     outstanding and shall automatically be canceled and shall cease to
     exist, and each certificate previously representing any such shares of
     Klamath Common Stock (each a "Certificate") shall thereafter represent
     the right to receive (i) the number of whole shares of Sterling Common
     Stock and (ii) cash in lieu of fractional shares into which the shares of
     Klamath Common Stock represented by such Certificate have been converted
     pursuant to this Agreement.  Certificates previously representing shares
     of Klamath Common Stock shall be exchanged for certificates representing
     whole shares of Sterling Common Stock and cash in lieu of fractional
     shares issued in consideration therefor upon the surrender of such
     Certificates in accordance with Section 2.2 hereof, without any interest
     thereon.  If after the date hereof and prior to the Effective Time
     Sterling should split or combine its common stock, or declare a dividend
     or other distribution in such common stock, with a distribution or record
     date, as applicable, prior to the Effective Time, then the Exchange Ratio
     shall be appropriately adjusted to reflect such split, combination,
     dividend or distribution.

          (c)  At the Effective Time, all shares of Klamath Common Stock that
     are owned by Klamath as treasury stock and all shares of Klamath Common
     Stock that are owned directly or indirectly by Sterling or Klamath or
     any Subsidiary of Klamath or Sterling (except for any issued and
     outstanding shares held in trust pursuant to the Klamath First Bancorp,
     Inc. 1996 Management Recognition and Development Plan (the "Klamath
     MRDP") or the Klamath First Federal Savings and Loan Association Employee
     Stock Ownership Plan (the "Klamath ESOP")) shall be canceled and shall
     cease to exist and no stock of Sterling or other consideration shall be
     delivered in exchange therefor.  For purposes of this Agreement,
     "Subsidiary" shall have the meaning given that term in Regulation S-X
     promulgated by the Securities and Exchange Commission (the "SEC").

          (d)  Certificates for fractions of shares of Sterling Common Stock
     will not be issued.  In lieu of a fraction of a share of Sterling Common
     Stock, each holder of Klamath Common Stock otherwise entitled to a
     fraction of a share of Sterling Common Stock shall be entitled to
     receive an amount of cash equal to the fraction of a share of the
     Sterling Common Stock to which such holder would otherwise be entitled,
     multiplied by the Sterling Determination Price (as defined in Section
     8.1(h)).  Following consummation of the Merger, no holder of Klamath
     Common Stock shall be entitled to dividends or any other rights in
     respect of any such fraction.

     1.5   STERLING COMMON STOCK.

     Each share of Sterling Common Stock issued and outstanding immediately
prior to the Effective Time shall be unchanged and shall remain issued and
outstanding as common stock of the Surviving Corporation.

      1.6   OPTIONS.

     At the Effective Time, each option granted by Klamath, pursuant to the
Klamath First Bancorp, Inc. 1996 Stock Option Plan (the "Klamath Stock Option
Plan"), to purchase shares of Klamath Common Stock (a "Klamath Option") which
is outstanding and unexercised immediately prior thereto shall be
automatically converted into an option to purchase shares of Sterling Common
Stock

                                      2





in an amount and at an exercise price determined as provided below and
otherwise subject to the terms of the Klamath Stock Option Plan under which
such option was granted:

          (a) The number of shares of Sterling Common Stock to be subject to
     the option immediately after the Effective Time shall be equal to the
     product of the number of shares of Klamath Common Stock subject to the
     option immediately before the Effective Time, multiplied by the Exchange
     Ratio, provided that any fractional shares of Sterling Common Stock
     resulting from such multiplication shall be rounded to the nearest
     whole share; and

          (b)  The exercise price per share of Sterling Common Stock under the
     option immediately after the Effective Time shall be equal to the
     exercise price per share of Klamath Common Stock under the option
     immediately before the Effective Time divided by the Exchange Ratio,
     provided that such exercise price shall be rounded to the nearest cent.
     The adjustment provided herein shall be and is intended to be effected
     in a manner that is consistent with Section 424(a) of the Code.  The
     duration and other terms of the option immediately after the Effective
     Time shall be the same as the corresponding terms in effect immediately
     before the Effective Time, except that all references to Klamath in the
     Klamath Stock Option Plan (and the corresponding references in the option
     agreement documenting such option) shall be deemed to be references to
     Sterling.

     1.7  RESERVATION OF SHARES AND SECURITIES FILINGS.

     At all times after the Effective Time, Sterling shall reserve for
issuance such number of shares of Sterling Common Stock as necessary so as to
permit the exercise of Klamath Options converted under Section 1.6 of this
Agreement.  Sterling shall make all filings required under federal and state
securities laws promptly after the Effective Time so as to permit the exercise
of such converted Klamath Options and the sale of the Sterling Common Stock
received by the optionee upon such exercise at and after the Effective Time.

     1.8  ARTICLES OF INCORPORATION.

     At the Effective Time, the Articles of Incorporation of Sterling, as in
effect at the Effective Time, shall be the Articles of Incorporation of the
Surviving Corporation.

     1.9  BYLAWS.

     At the Effective Time, the Bylaws of Sterling, as in effect immediately
prior to the Effective Time, shall be the Bylaws of the Surviving Corporation.


     1.10 DIRECTORS AND OFFICERS.

     Subject to Section 6.16, the directors and officers of Sterling
immediately prior to the Effective Time shall continue to be directors and
officers of the Surviving Corporation.

     1.11 TAX CONSEQUENCES.

     It is intended that the Merger, either alone or in conjunction with the
Institution Merger, shall constitute a reorganization within the meaning of
Section 368(a) of the Code, and that this Agreement shall constitute a "plan
of reorganization" for the purposes of the Code.

     1.12 ACCOUNTING TREATMENT.

     It is intended that the Merger shall be accounted for as a "purchase"
under accounting principles generally accepted in the United States of America
("GAAP").

                                      3






                                 ARTICLE II

     2.1  STERLING TO MAKE SHARES AVAILABLE.

     At or prior to the Effective Time, Sterling shall deposit, or shall cause
to be deposited, with Sterling's transfer agent, Mellon Investor Services,
LLC, or such other similarly-qualified bank, trust company or transfer agent
as Sterling may select (the "Exchange Agent"), for the benefit of the holders
of Certificates, for exchange in accordance with this Article II, certificates
representing the shares of Sterling Common Stock and the cash in lieu of
fractional shares (such cash and certificates for shares of Sterling Common
Stock, being hereinafter referred to as the "Exchange Fund") to be issued
pursuant to Section 1.4 and paid pursuant to Section 2.2(a) hereof in exchange
for outstanding shares of Klamath Common Stock.

     2.2  EXCHANGE OF SHARES; CONVERSION OF OPTIONS.

          (a)  Within ten days after the Effective Time, the Exchange Agent
     shall mail to each holder of record of a Certificate or Certificates a
     form letter of transmittal (which shall specify that delivery shall be
     effected, and risk of loss and title to the Certificates shall pass,
     only upon delivery of the Certificates to the Exchange Agent) and
     instructions for use in effecting the surrender of the Certificates in
     exchange for certificates representing the shares of Sterling Common
     Stock and the cash in lieu of fractional shares into which the shares of
     Klamath Common Stock represented by such Certificate or Certificates
     shall have been converted pursuant to this Agreement.  Upon surrender of
     a Certificate for exchange and cancellation to the Exchange Agent,
     together with such letter of transmittal, duly executed, the holder of
     such Certificate shall be entitled to receive in exchange therefor (x) a
     certificate representing that number of whole shares of Sterling Common
     Stock to which such holder of Klamath Common Stock shall have become
     entitled pursuant to the provisions hereof and (y) a check representing
     the amount of cash in lieu of a fractional share, if any, which such
     holder has the right to receive in respect of the Certificate surrendered
     pursuant to the provisions of this Article II, and the Certificate so
     surrendered shall forthwith be canceled.  No interest will be paid or
     accrued on the cash in lieu of fractional shares, unpaid dividends,
     and distributions, if any, payable to holders of Certificates.

          (b)  No dividends or other distributions declared after the
     Effective Time with respect to Sterling Common Stock and payable to the
     holders of record thereof shall be paid to the holder of any unsurren-
     dered Certificate until the holder thereof shall surrender such Certifi-
     cate in accordance with this Article II.  After the surrender of a Certi-
     ficate in accordance with this Article II, the record holder thereof
     shall be entitled to receive any such dividends or other distributions,
     without any interest thereon, which theretofore had become payable with
     respect to shares of Sterling Common Stock represented by such
     Certificate.

          (c)  If any certificate representing shares of Sterling Common Stock
     is to be issued in a name other than that in which the Certificate
     surrendered in exchange therefor is registered, it shall be a condition
     of the issuance thereof that the Certificate so surrendered shall be
     properly endorsed (or accompanied by an appropriate instrument of
     transfer) and otherwise in proper form for transfer, and that the person
     requesting such exchange shall pay to the Exchange Agent in advance any
     transfer or other taxes required by reason of the issuance of a
     certificate representing shares of Sterling Common Stock in any name
     other than that of the registered holder of the Certificate surrendered,
     or shall

     establish to the satisfaction of the Exchange Agent that such tax has
     been paid or is not payable.

          (d)  After the Effective Time, there shall be no transfers on the
     stock transfer books of Klamath of the shares of Klamath Common Stock
     that were issued and outstanding immediately prior to the Effective Time.
     If, after the Effective Time, Certificates representing such shares are

                                        4






     presented for transfer to the Exchange Agent, they shall be canceled and
     exchanged for certificates representing shares of Sterling Common Stock
     as provided in this Article II.

          (e)  Any portion of the Exchange Fund that remains unclaimed by the
     shareholders of Klamath for six months after the Effective Time shall be
     returned to Sterling.  Any shareholders of Klamath who have not thereto-
     fore complied with this Article II shall thereafter look only to Sterling
     for payment of their shares of Sterling Common Stock, cash in lieu of
     fractional shares and unpaid dividends and distributions on Sterling
     Common Stock deliverable in respect of each share of Klamath Common Stock
     such shareholder holds as determined pursuant to this Agreement, in each
     case, without any interest thereon.  Notwithstanding the foregoing, none
     of Sterling, Klamath, the Exchange Agent or any other person shall be
     liable to any former holder of shares of Klamath Common Stock for any
     amount properly delivered to a public official pursuant to applicable
     abandoned property, escheat or similar laws.

          (f)  In the event any Certificate shall have been lost, stolen or
     destroyed, upon the making of an affidavit of that fact by the person
     claiming such Certificate to be lost, stolen or destroyed and, if
     required by Sterling, the posting by such person of a bond in such
     amount as Sterling may reasonably direct as indemnity against any claim
     that may be made against it with respect to such Certificate, the
     Exchange Agent will issue in exchange for such lost, stolen or destroyed
     Certificate the shares of Sterling Common Stock and cash in lieu of
     fractional shares deliverable in respect thereof pursuant to this
     Agreement.

                                ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF KLAMATH

     Klamath hereby makes the following representations and warranties to
Sterling, each of which is being relied upon by Sterling as a material
inducement to Sterling to enter into and perform this Agreement.

     3.1  CORPORATE ORGANIZATION.

          (a)  Klamath is a corporation duly organized, validly existing and
     in good standing under the laws of the State of Oregon.  Klamath has the
     corporate and other power and authority to own or lease all of its
     properties and assets and to carry on its business as it is now being
     conducted, and is duly licensed or qualified to do business in each
     jurisdiction in which the nature of any material business conducted by it
     or the character or location of any material properties or assets owned
     or leased by it makes  such licensing or qualification necessary, except
     where the failure to be so licensed or qualified would not have a
     Material Adverse Effect (as defined below) on Klamath.  Klamath is duly
     registered as a savings and loan holding company with the Office of
     Thrift Supervision (the "OTS")under the Home Owners' Loan Act of 1933(the
     "HOLA").  Klamath First Federal, Klamath First Financial Services, Inc.,
     Klamath First Capital Trust I, Klamath First Capital Trust II and Pacific
     Cascades Financial, Inc. are the only Subsidiaries of Klamath. Section
     3.1(a) of the disclosure schedule which is attached hereto as Exhibit B
     (the "Klamath Disclosure Schedule") sets forth true, correct and complete
     copies of the Articles of Incorporation and Bylaws of Klamath as in
     effect as of the date of this Agreement.

          (b)  Klamath First Federal is a federal stock savings and loan
     association duly organized and validly existing under the laws of the
     United States.  The deposit accounts of Klamath First Federal are insured
     by the Federal Deposit Insurance Corporation (the "FDIC") to the fullest
     extent permitted by Law (as defined in Section 3.3), and all premiums and
     assessments due the FDIC in connection therewith have been paid by
     Klamath First Federal.  Klamath First Federal is a "Qualified Thrift
     Lender" as defined in Section 10(m) of HOLA and the liquidation account
     established by Klamath First Federal in connection with its conversion
     from mutual to stock form has been maintained since its establishment in
     accordance with applicable laws and the records

                                        5





     with respect to said account (including subaccounts) are complete and
     accurate in all material respects.  As of the date hereof, Klamath First
     Federal is "well-capitalized" (as that term is defined at 12 C.F.R.
     565.4) and its most recent examination rating under the Community
     Reinvestment Act of 1977 was "satisfactory."  Klamath First Financial
     Services, Inc. and Pacific Cascades Financial, Inc. are the only
     Subsidiaries of Klamath First Federal.  Klamath First Federal, Klamath
     First Financial Services, Inc. and Pacific Cascades Financial, Inc.,
     respectively, have the corporate and other power and authority to own or
     lease all of their properties and assets and to carry on their business
     as it is now being conducted and are duly licensed or qualified to do
     business in each jurisdiction in which the nature of any material
     business conducted by them or the character or location of any material
     properties or assets owned or leased by them makes such licensing or
     qualification necessary, except where the failure to be so licensed or
     qualified would not have a Material Adverse Effect on Klamath.  Section
     3.1(b) of the Klamath Disclosure Schedule sets forth true, correct and
     complete copies of the Charter and Bylaws of Klamath First Federal and
     the Articles of Incorporation and Bylaws (or equivalent documents) of
     Klamath First Financial Services, Inc. and Pacific Cascades Financial,
     Inc. as in effect as of the date of this Agreement.

          (c)  Except as set forth on Schedule 3.1(c) of the Klamath
     Disclosure Schedule, the minute books of Klamath and its Subsidiaries, in
     all material respects, contain accurate records of all meetings and
     accurately reflect all other material actions taken by the shareholders,
     the Boards of Directors and all standing committees of the Boards of
     Directors since October 1, 1999.

          (d)  The term "Material Adverse Effect" with respect to Sterling,
     Klamath or the Surviving Corporation, as the case may be, means a
     condition, event, change or occurrence that has had or is reasonably
     likely to have a material adverse effect upon the financial condition,
     results of operations or business of such party and its Subsidiaries,
     taken as a whole, or the ability of such party to timely perform its
     obligations under, and to consummate the transactions contemplated by,
     this Agreement; provided, however, that in determining whether a Material
     Adverse Effect has occurred there shall be excluded any effect on the
     referenced party the cause of which is (i) any change in banking, savings
     association or similar laws, rules or regulations of general
     applicability or interpretations thereto by courts or governmental
     authorities, (ii) any change in GAAP or regulatory accounting
     requirements applicable to banks, savings associations or their holding
     companies generally, (iii) any action or omission of Sterling, Klamath or
     any Subsidiary of either of them taken with the prior written consent of
     Sterling or Klamath, as applicable, or as otherwise expressly
     contemplated by this Agreement, (iv) any changes in general economic,
     market or political conditions affecting banks, thrifts or their holding
     companies generally provided that the effect of such changes described in
     this clause (iv) shall not be excluded to the extent of any materially
     disproportionate impact (if any) they have on such party and (v) the cost
     of terminating the contracts with the officers and directors of Klamath
     that are specified in Section 3.12.

     3.2  CAPITALIZATION.

          (a)  The authorized capital stock of Klamath consists of 35,000,000

     outstanding, including 293,486 shares held by the Klamath ESOP and 53,494

     Klamath Stock Option Plan (of which options for 642,940 shares are
     currently outstanding).  No shares of the said preferred stock are issued
     and outstanding.  All of the issued and outstanding shares of Klamath
     Common Stock have been duly authorized and validly issued and are fully
     paid, nonassessable and free of preemptive rights, with no personal
     liability attaching to the ownership thereof.  Except for the

                                        6





     Klamath Stock Option Plan and the Klamath MRDP, Klamath does not have and
     is not bound by any outstanding subscriptions, options, warrants, calls,
     commitments or agreements of any character calling for the purchase or
     issuance of any shares of Klamath Common Stock or any other equity
     security of Klamath or any securities representing the right to purchase
     or otherwise receive any shares of Klamath Common Stock or any other
     equity security of Klamath.  The names of each optionee, the date of each
     option to purchase Klamath Common Stock granted, the number of shares
     subject to each such option and the price at which each such option may
     be exercised under the Klamath Stock Option Plan are set forth in Section
     3.2(a) of the Klamath Disclosure Schedule and no such option expires more
     than ten years from the date of the grant thereof.

          (b)  Klamath owns, directly or indirectly, all of the issued and
     outstanding shares of capital stock of its Subsidiaries, free and clear
     of all liens, charges,  encumbrances and security interests whatsoever,
     and all of such shares are duly authorized and validly issued and are
     fully paid, nonassessable and free of preemptive rights, with no personal
     liability attaching to the ownership thereof.  No Klamath Subsidiary has
     or is bound by any outstanding subscriptions, options, warrants, calls,
     commitments or agreements of any character calling for the purchase or
     issuance of any shares of its capital stock or any other equity security
     or any securities representing the right to purchase or otherwise receive
     any shares of capital stock or any other equity security.

     validly approved by the Board of Directors of Klamath.  The Board of
     Directors of Klamath, at a meeting duly called and held, has determined
     that this Agreement and the transactions contemplated hereby are fair to

     Common Stock, no other corporate proceedings on the part of Klamath
     (except for matters related to setting the date, time, place and record
     date for the said meeting) are necessary to approve this Agreement or to
     consummate the transactions contemplated hereby.  This Agreement has been
     duly and validly executed and delivered by Klamath and (assuming due
     authorization, execution and delivery by Sterling of this Agreement) this
     Agreement constitutes a valid and binding obligation of Klamath,
     enforceable against Klamath in accordance with its terms, except as
     enforcement may be limited by general principles of equity whether
     applied in a court of law or a court of equity and by bankruptcy,
     insolvency, fraudulent conveyance and similar Laws affecting creditors'
     rights and remedies generally.

     executed and delivered by Klamath First Federal and will (assuming due
     authorization, execution and delivery by Sterling Savings Bank)
     constitute a valid and binding obligation of Klamath First Federal,
     enforceable against Klamath First Federal in accordance with its terms,
     except as enforcement may be limited by general principles of equity


                                        7





     whether applied in a court of law or a court of equity and by
     bankruptcy, insolvency and similar Laws affecting creditors' rights and
     remedies generally.

          (c)  Neither the execution and delivery of this Agreement by Klamath
     or the Institution Merger Agreement by Klamath First Federal, nor the
     consummation by Klamath or its Subsidiaries, as the case may be, of the
     transactions contemplated hereby or thereby, nor compliance by Klamath or
     its Subsidiaries, as the case may be, with any of the terms or provisions

     notice or lapse of time, or both, would constitute a material fault)
     under, result in the termination of or a right of termination or
     cancellation under, accelerate the performance required by, or result in
     the creation of any lien, pledge, security interest, charge or other
     encumbrance upon any of the respective properties or assets of Klamath or
     any of its Subsidiaries under any of the terms, conditions or provisions
     of any material note, bond, mortgage, indenture, deed of trust, license,
     lease, agreement or other material instrument or obligation to which
     Klamath or any of its Subsidiaries is a party, or by which they or any of
     their respective properties or assets may be bound or affected.

     all statutes, laws, ordinances, rules, regulations and other rules of law
     enacted, promulgated or issued by any court, administrative agency or
     commission or other governmental authority or instrumentality or
     self-regulatory organization including, without limitation, the OTS, the

     upon the actuarial assumptions used for funding purposes in the most

     such Plan, did not, as of its latest valuation date, exceed the then
     current value of the assets of such Plan allocable to such accrued

     benefits, and there has not been a material adverse change in the
     financial condition of such Plans, (iv) no Plan provides benefits,
     including, without limitation, death or medical benefits (whether or not
     insured), with respect to current or former employees of Klamath or any

     ERISA) under Title IV of ERISA, or any material liability in connection
     with the termination or reorganization of a multiemployer pension plan,
     (viii) all contributions or other amounts required to be paid by Klamath,
     any of its Subsidiaries or any ERISA Affiliates as of the Effective Time

     with respect to each Plan in respect of current or prior plan years have
     been paid or accrued in accordance with GAAP and Section 412 of the Code,
     (ix) neither Klamath nor any Subsidiary or ERISA Affiliate has engaged in

     payment" within the meaning of Code Section 280G, nor is there

     3.12 CERTAIN CONTRACTS.

          (a)  Except as set forth at Section 3.12 of the Klamath Disclosure
     Schedule, neither Klamath nor any of its Subsidiaries is a party to or
     bound by any written or oral contract, arrangement or commitment: (i)
     with respect to the employment of any directors, officers, employees or
     consultants, (ii) which, upon the consummation of the transactions
     contemplated by this Agreement will (either alone or upon the occurrence
     of any additional acts or events) result in or accelerate any payment

                                        12





     in fiscal year 2002 of more than $200,000 or which could reasonably be
     expected to involve payments during fiscal year 2003 of more than
     $200,000, other than any such contract that is terminable at will on 60
     days or less notice without payment of a penalty in excess of $10,000.
     Section 3.12(a) of the Klamath Disclosure Schedule sets forth true,
     correct and complete copies of all employment, consulting and deferred
     compensation agreements to which Klamath or any of its Subsidiaries is a
     party.  Each contract, arrangement or commitment of the type described in
     this Section 3.12(a) is referred to herein as a "Klamath Contract."

          (b)  (i) Each Klamath Contract is a valid and binding commitment of
     Klamath and is in full force and effect, (ii) each of Klamath and its
     Subsidiaries has in all material respects performed all obligations
     required to be performed by it to date under each Klamath Contract, (iii)
     no event or condition exists which constitutes or, after notice or lapse
     time or both, would constitute, a material default on the part of Klamath
     or any of its Subsidiaries under any such Klamath Contract (other than
     the transactions contemplated by this Agreement) and neither Klamath nor
     any of its Subsidiaries has received notice of any violation or imminent
     violation of any Klamath Contract by any other party thereto.

     3.13 REGULATORY AGREEMENTS.

     Neither Klamath nor any of its Subsidiaries is subject to any cease-and-
desist or other order issued by, or is a party to any written agreement,
consent agreement or memorandum of understanding with, or is a party to any
commitment letter or similar undertaking to, or is subject to any order or
directive by, or has been a recipient of any extraordinary supervisory letter
from, or has adopted any board resolutions (each of the foregoing, a
"Regulatory Agreement"), at the request of any Governmental Entity that
restricts the conduct of its business or that in any manner relates to its
capital adequacy, its credit policies, its management or its business, nor has
Klamath or any of its Subsidiaries been advised by any Governmental Entity
that it is considering issuing or requesting any Regulatory Agreement.

     3.14 STATE TAKEOVER LAWS.

     Klamath and its Board of Directors have taken all necessary action so
that the provisions of Section 60.835 of the OBCA and any applicable
provisions of the takeover laws of any other state (and any comparable
provisions of Klamath's Articles of Incorporation and Bylaws) do not and will
not apply to this Agreement, the Merger or the transactions contemplated
hereby or thereby.

     3.15 ENVIRONMENTAL MATTERS.

     Except as set forth in Schedule 3.15, there are no legal, administrative,
arbitral or other proceedings, claims, actions, causes of action, private
environmental investigations or remediation activities or governmental
investigations of any nature seeking to impose, or that reasonably could be
expected to result in the imposition, on Klamath or any of its Subsidiaries of
any liability or obligation arising under common law standards relating to
environmental protection, human health or safety, or under any local, state or
federal environmental statute, regulation or ordinance, including, without
limitation, the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended (collectively, the "Environmental Laws"),
pending or, to the knowledge of Klamath, threatened against Klamath or any of
its Subsidiaries, which liability or obligation would have or would reasonably
be expected to have a Material Adverse Effect on Klamath. To the knowledge of
Klamath, there is no reasonable basis for any such proceeding, claim, action
or governmental investigation that would impose any liability or obligation
that would have or would reasonably be expected to have a Material Adverse
Effect on Klamath. To the knowledge of Klamath, during or prior to the period
of (i) its or any of its Subsidiaries' ownership or operation of any of their
respective current properties, (ii) its or any of its Subsidiaries'
participation in the management of any property, or (iii) its or any of its
Subsidiaries' holding of a security interest or other interest in any
property, there were no releases or threatened releases of hazardous, toxic,
radioactive or dangerous materials or other materials


                                        13





regulated under Environmental Laws in, on, under or affecting any such
property which would reasonably be expected to have a Material Adverse Effect
on Klamath. Neither Klamath nor any of its Subsidiaries is subject to any
agreement, order, judgment, decree, letter or memorandum by or with any court,
governmental authority,  egulatory agency or third party imposing any material
liability or obligation pursuant to or under any Environmental Law that would
have or would reasonably be expected to have a Material Adverse Effect on
Klamath.

     3.16 ALLOWANCES FOR LOSSES.

     All allowances for losses reflected in Klamath's most recent financial
statements referred to in Section 3.6 complied with all Laws and are reported
in accordance with GAAP.  Neither Klamath nor any of its Subsidiaries has been
notified by any Governmental Entity or by Klamath's independent auditor, in
writing or otherwise, that: (i) such allowances are inadequate, (ii) the
practices and policies of Klamath or any of its Subsidiaries in establishing
such allowances and in accounting for non-performing and classified assets
generally fail to comply with applicable accounting or regulatory
requirements, or (iii) such allowances are inadequate or inconsistent with the
historical loss experience of Klamath or any of its Subsidiaries.  Section
3.16 of the Klamath Disclosure Schedule sets forth a complete list of all
extensions of credit and other real estate owned ("OREO") that have been
classified as special mention, substandard, doubtful, loss or words of similar
import.  All OREO, if any, held by Klamath or any of its Subsidiaries is being
carried at fair value in accordance with GAAP.

     3.17 PROPERTIES AND ASSETS.

     Section 3.17 of the Klamath Disclosure Schedule lists as of the date of
this Agreement (i) all real property owned by Klamath and its Subsidiaries;
(ii) each real property lease, sublease or installment purchase arrangement to
which Klamath or any of its Subsidiaries is a party; (iii) a description of
each contract for the purchase, sale, or development of real estate to which
Klamath or any of its Subsidiaries is a party; and (iv) all items of Klamath's
or any of its Subsidiaries' tangible personal property and equipment with a
net book value of $30,000 or more or having any annual lease payment of
$25,000 or more.  Except for (a) items reflected in Klamath's consolidated
financial statements as of September 30, 2002 referred to in Section 3.6
hereof, (b) exceptions to title that do not interfere materially with
Klamath's or any of its Subsidiaries' use and enjoyment of owned or leased
real property (other than OREO), (c) liens for current real estate taxes not
yet delinquent, or being contested in good faith, properly reserved against,
(d) properties and assets sold or transferred in the ordinary course of
business consistent with past practices since September 30, 2002, and (e)
items listed in Section 3.17 of the Klamath Disclosure Schedule, Klamath and
its Subsidiaries have good and, as to owned real property, marketable and
insurable title to all their properties and assets, free and clear of all
material liens, claims, charges and other encumbrances.  Klamath and its
Subsidiaries, as lessees, have the right under valid and subsisting leases to
occupy, use and possess all property leased by them.  All properties and fixed
assets used by Klamath and its Subsidiaries are in good operating condition
and repair (subject to ordinary wear and tear) suitable for the purposes for
which they are currently utilized and, to the knowledge of Klamath, comply in
all material respects with all Laws relating thereto now in effect.  Klamath
and its Subsidiaries enjoy peaceful and undisturbed possession under all
leases for the use of all property under which they are the lessees, and all
leases to which Klamath or any of its Subsidiaries is a party are valid and
binding obligations of Klamath or any of its Subsidiaries in accordance with
the terms thereof.  Neither Klamath nor any of its Subsidiaries is in material
default with respect to any such lease, and there has occurred no default by
Klamath or any of its Subsidiaries or event which with the lapse of time or
the giving of notice, or both, would constitute a material default by Klamath
or any of its Subsidiaries under any such lease.  To the knowledge of Klamath,
there are no Laws, conditions of record, or other impediments which materially
interfere with the intended use by Klamath or any of its Subsidiaries of any
of the property owned, leased, or occupied by them.


                                        14





     3.18 INSURANCE.

          (a)  Klamath and its Subsidiaries are insured with reputable
     insurers against such risks and in such amounts as the management of
     Klamath reasonably has determined to be prudent in accordance with
     industry practice.  Klamath and its Subsidiaries are in material
     compliance with their insurance policies and are not in default under any
     of the material terms thereof.  Each such policy is outstanding and in
     full force and effect and, except for policies insuring against potential
     liabilities of officers, directors and employees of Klamath and its
     Subsidiaries and policies on which a third party is named as an
     additional insured, Klamath or the relevant Subsidiary thereof is the
     sole beneficiary of such policies.  All premiums and other payments due
     under any such policy have been paid, and all claims thereunder have been
     filed in due and timely fashion.

          (b)  The existing insurance carried by Klamath and its Subsidiaries
     is sufficient  for compliance by Klamath and its Subsidiaries with all
     requirements of Law and agreements to which Klamath or its Subsidiaries
     are subject.  Section 3.18 of the Klamath Disclosure Schedule contains a
     true, correct and complete list of all material insurance policies and
     bonds maintained by Klamath and its Subsidiaries, including the name of
     the insurer, the policy number, the type of policy and any applicable
     deductibles.  True, correct and complete copies of all such policies and
     bonds set forth in Section 3.18 of the Klamath Disclosure Schedule, as in
     effect on the date hereof, have been delivered or made available to
     Sterling.

     3.19 COMPLIANCE WITH APPLICABLE LAWS.

          Each of Klamath and its Subsidiaries has complied and is in
     compliance in all material respects with all Laws applicable to it or to
     the operation of its business.  Neither Klamath nor its Subsidiaries have
     received any notice of any material alleged or threatened claim,
     violation or liability under any such Laws that has not heretofore been
     cured and for which there is no remaining liability.

     3.20 LOANS.

          (a)  To the knowledge of Klamath, all written or oral loans, loan
     commitments, letters of credit and other extensions of credit owned by
     Klamath or any of its Subsidiaries, or in which Klamath or any of its
     Subsidiaries has an interest ("Loans"), comply in all material respects
     with all Laws, including, but not limited to, applicable usury statutes,
     underwriting and recordkeeping requirements and the Truth in Lending Act,
     the Equal Credit Opportunity Act and the Real Estate Settlement
     Procedures Act, and other applicable consumer protection statutes and the
     regulations thereunder.

          (b)  All Loans have been made or acquired by Klamath in all material
     respects in accordance with Board of Director-approved Loan policies.
     Each of Klamath and its Subsidiaries holds the Loans contained in its
     Loan portfolio for its own benefit to the extent of its interest shown
     therein; to the knowledge of Klamath, such Loans include liens having
     the priority indicated by their terms, subject, as of the date of
     recordation or filing of applicable security instruments, only to such
     exceptions as are discussed in attorneys' opinions regarding title or in
     title insurance policies in the mortgage files relating to the Loans
     secured by real property or are not material as to the collectability of
     such Loans; to the knowledge of Klamath, all Loans owned by Klamath and
     its Subsidiaries are with full recourse to the borrowers, and neither
     Klamath nor its Subsidiaries have taken any action that would result in a
     waiver or negation of any rights or remedies available against the
     borrower or guarantor, if any, on any Loan, other than



     in the ordinary course of business.  All applicable remedies against all
     borrowers and guarantors are enforceable except as such enforcement may
     be limited by general principles of equity whether applied in a court of
     law or a court in equity and by bankruptcy, insolvency, fraudulent
     conveyance, and similar Laws affecting creditors' rights and remedies
     generally.  Except as set forth at Section 3.20(b) of the Klamath
     Disclosure Schedule, all Loans purchased or originated by Klamath or any
     of its

                                        15





     Subsidiaries and subsequently sold by Klamath or any of its
     Subsidiaries have been sold without recourse to Klamath or any of its
     Subsidiaries (other than with respect to customary representations and
     warranties) and without any liability under any yield maintenance or
     similar obligation.  True, correct and complete copies of Loan
     delinquency reports prepared by Klamath and its Subsidiaries, which
     reports include all Loans delinquent or otherwise in default as of June
     30, 2003, are set forth in Section 3.20(b) of the Klamath Disclosure
     Schedule.  True, correct and complete copies of the currently effective
     lending policies of Klamath and its Subsidiaries have been furnished or
     made available to Sterling.

          (c)  Except as set forth in Section 3.20(c) of the Klamath
     Disclosure Schedule, each outstanding Loan participation sold by Klamath
     or any of its Subsidiaries was sold with the risk of non-payment of all
     or any portion of that underlying Loan to be shared by each participant
     (including Klamath or any of its Subsidiaries) proportionately to the
     share of such Loan represented by such participation without any recourse
     of such other lender or participant to Klamath or any of its Subsidiaries
     for payment or repurchase of the amount of such Loan represented by the
     participation or liability under any yield maintenance or similar
     obligation.  Each of Klamath and its Subsidiaries has properly fulfilled
     in all material respects its contractual responsibilities and duties in
     any Loan in which it acts as the lead lender or servicer and has complied
     in all material respects with its duties as required under applicable
     regulatory requirements.

          (d)  Except as set forth on Schedule 3.20(d), to the knowledge of
     Klamath, each of Klamath and its Subsidiaries has properly perfected or
     caused to be properly perfected all security interests, liens, or other
     interests in any collateral securing any Loans made by it.

     3.21 UNDISCLOSED LIABILITIES.

     Except for (i) those liabilities that are accrued for or recorded in the
Klamath Exchange Act Reports or (ii) liabilities incurred in the ordinary
course of business consistent with past practice since the latest Klamath
Exchange Act Report, neither Klamath nor any of its Subsidiaries has incurred
any liability of any nature whatsoever (whether absolute, accrued or
contingent or otherwise and whether due or to become due) that, either alone
or when combined with all similar liabilities, has had, or would be reasonably
expected to have, a Material Adverse Effect on Klamath.

     3.22 INTELLECTUAL PROPERTY RIGHTS.

     Except as set forth in Schedule 3.22 of the Klamath Disclosure Schedule,
Klamath and each of its Subsidiaries owns or possesses all legal rights, or is
licensed or otherwise has the right to use, all proprietary rights, including
without limitation all trademarks, trade names, service marks and copyrights,
that are material to the conduct of their existing businesses.  Neither
Klamath nor any of its Subsidiaries is bound by or a party to any options,
licenses or agreements of any kind with respect to any trademarks, service
marks or trade names which it claims to own.  Neither Klamath nor any of its
Subsidiaries has received any communications alleging that any of them has
violated any of the patents, trademarks, service marks, trade names,
copyrights or trade secrets or any other proprietary rights of any other

     redeem or otherwise acquire any shares of the capital stock of Klamath or
     Klamath First Federal, or any securities convertible into or exercisable
     for any shares of the capital stock of Klamath or Klamath First Federal;

          (c)  issue, allocate, deliver or sell, or authorize or propose the
     issuance, delivery or sale of, any shares of its capital stock or any
     securities convertible into or exercisable for, or any rights, warrants
     or options to acquire, any such shares, or enter into any agreement with
     respect to any of the foregoing, other than the issuance of Klamath
     Common Stock pursuant to stock options or similar rights to acquire
     Klamath Common Stock granted pursuant to the Klamath Stock Option Plan
     and outstanding prior to the date of this Agreement, and delivery upon
     vesting of Klamath

                                        23





     MRDP shares that were awarded prior to the date of this Agreement, free
     from restriction pursuant to the Klamath MRDP, in each case in accordance
     with their present terms;

          (d)  amend its Articles of Incorporation, Bylaws or other similar
     governing documents unless required to do so by applicable law or
     regulation or by regulatory directive;

          (e)  authorize or permit its officers, directors, employees, agents,
     advisors and affiliates (collectively, "Representatives") to (i)
     initiate, solicit, encourage or knowingly facilitate any inquiries or
     proposals with respect to, any Acquisition Proposal (as defined below) or
     (ii) engage in any negotiations concerning, or provide any nonpublic
     information to, or have any discussions with, any person relating to, any
     Acquisition Proposal; provided that, in the event Klamath receives an
     unsolicited bona fide Acquisition Proposal and Klamath's Board of
     Directors concludes in good faith that such Acquisition Proposal
     constitutes or is reasonably likely to result in a Superior Proposal (as
     defined below), Klamath may, and may permit its Subsidiaries and its and
     their Representatives to, take any action described in clause (ii) above
     to the extent that the Board of Directors of Klamath concludes in good
     faith (based on the advice of its outside counsel) that failure to take
     such actions would more likely than not result in a violation of its
     fiduciary duties under applicable law.  Prior to providing any nonpublic
     information permitted to be provided pursuant to this Section, Klamath
     shall have entered into a confidentiality agreement with such third party
     on terms no less favorable to Klamath than the Confidentiality Agreement
     (as defined in Section 6.2).  Klamath will immediately cease and cause to
     be terminated any activities, discussions or negotiations conducted
     before the date of this Agreement with any persons other than Sterling
     with respect to any Acquisition Proposal and will use its reasonable best
     efforts to enforce any confidentiality or similar agreement relating to
     an Acquisition Proposal.  Klamath will promptly (within one business day)
     advise Sterling following receipt of any Acquisition Proposal of the
     substance thereof (including the identity of the person making such
     Acquisition Proposal), and will keep Sterling apprised of any related
     developments, discussions and negotiations (including the terms and
     conditions of the Acquisition Proposal) on a current basis. As used in
     this Agreement, "Acquisition Proposal" shall mean any tender or exchange
     offer, proposal for a merger, consolidation or other business combination
     involving Klamath or any of its Subsidiaries or any proposal or offer to
     acquire in any manner more than 15% of the voting power in, or more than
     15% of the business, assets or deposits of, Klamath or any of its
     Subsidiaries, other than the transactions contemplated by this Agreement.
     As used in this Agreement, "Superior Proposal" means any bona fide
     written Acquisition Proposal which the Board of Directors of Klamath
     concludes in good faith to be more favorable from a financial point of
     view to its shareholders than the Merger and the other transactions
     contemplated hereby, (1) after receiving the advice of its financial
     advisors (who shall be regionally recognized investment banking firms),
     (2) after taking into account the likelihood of consummation of such
     transaction on the terms set forth therein (as compared to, and with due
     regard for, the terms herein) and (3) after taking into account all legal
     (with the advice of outside counsel), financial (including the financing
     terms of any such proposal), regulatory and other aspects of such
     proposal and any other relevant factors permitted under applicable Law.
     For purposes of the definition of "Superior Proposal," the references to
     "more than 15%" in the definition of Acquisition Proposal shall be deemed
     to be references to "a majority" and the definition of Acquisition
     Proposal shall only refer to a transaction involving Klamath and not
     its Subsidiaries;

          (f)  other than commitments entered into prior to the date of this
     Agreement, as set forth in Schedule 5.1(f) of the Klamath Disclosure
     Schedule, make capital expenditures aggregating in excess of $250,000,
     except for emergency repairs and replacements;

          (g)  enter into any new line of business;


                                        24





          (h)  acquire or agree to acquire, by merging or consolidating with,
     or by purchasing an equity interest in or the assets of, or by any other
     manner, any business or any corporation, partnership, association or
     other business organization or division thereof or otherwise acquire any
     assets, other than in connection with foreclosures, settlements in lieu
     of foreclosure or troubled loan or debt restructurings, or in the
     ordinary course of business consistent with past practices;

          (i)  take any action that is intended or may reasonably be expected
     to result in any of its representations and warranties set forth in this
     Agreement being or becoming untrue or in any of the conditions to the
     Merger set forth in Article VII not being satisfied, or in a violation of
     any provision of this Agreement or the Institution Merger Agreement,
     except, in every case, as may be required by applicable Law;

          (j)  change its methods of accounting in effect at September 30,
     2002 except as required by changes in GAAP or regulatory accounting
     principles as concurred to by Klamath's independent auditors;

     to maintain qualification pursuant to the Code, adopt, amend, renew or
     terminate any Plan or any agreement, arrangement, plan or policy between
     Klamath or Klamath First Federal and one or more of its current or former
     directors, officers or employees, (ii) other than normal annual increases
     in pay, consistent with past practice, for employees not subject to an
     employment, change of control or severance agreement, increase in any
     manner the compensation of any employee or director or pay any benefit
     not required by any Plan or agreement as in effect as of the date hereof
     (including, without limitation, the granting of stock options, stock
     appreciation rights, restricted stock, restricted stock units or
     performance units or shares), (iii) enter into, modify or renew any
     contract, agreement, commitment or arrangement providing for the payment

     employees not subject to an employment, change of control or severance
     agreement, (iv) hire any new employee at an annual compensation in excess
     of $60,000, (v) pay aggregate expenses of more than $50,000 of employees

     employee, or (vii) except as itemized on Schedule 5.1(k) of the Klamath

     course of business consistent with past practices;

          (o)  make any new Loans to, modify the terms of any existing Loan

     Federal's ability to consummate the transactions contemplated by this
     Agreement; or

          (v)  agree or commit to do any of the actions set forth in clauses
     (a) - (u) of this Section 5.1.

     The consent of Sterling to any action by Klamath or Klamath First Federal

President of Sterling.  With respect to any written request by Klamath for
Sterling's consent to any non-permitted action of Klamath or Klamath First

Sterling's written objection to such action within five business days after
the date of delivery of such written request to Sterling.

     5.2  COVENANTS OF STERLING.

     During the period from the date of this Agreement and continuing until
the Effective Time, except as expressly contemplated or permitted by this
Agreement or with Klamath's prior written consent, Sterling shall not, and
shall not permit Sterling Savings Bank to:

          (a)  take any action that will result in any of Sterling's
     representations and warranties set forth in this Agreement being or
     becoming untrue or any of the conditions to the Merger set forth in
     Article VII not being satisfied or in a violation of any provision of
     this Agreement or the Institution Merger Agreement, except, in every
     case, as may be required by applicable Law;

          (b)  take any action, or amend the Sterling Articles of
     Incorporation or Bylaws, the effect of which would be to materially and
     adversely affect the rights or powers of shareholders generally;

          (c)  take or omit to take any other action that would materially
     adversely affect or materially delay the ability of Sterling to obtain

     affect Sterling's or Sterling Savings Bank's ability to consummate the
     transactions contemplated by this Agreement; or

          (d)  agree or commit to do any of the actions set forth in clauses
     (a) - (c) of this Section 5.2.

                                        26





     The consent of Klamath to any action by Sterling or Sterling Savings Bank
that is not permitted by any of the preceding paragraphs shall be evidenced
only by a writing signed by the President or any Executive or Senior Vice
President of Klamath.

     5.3  MERGER COVENANTS.

          (a)  Notwithstanding that Klamath believes that it has established
     all allowances and taken all provisions for losses required by GAAP and
     applicable Laws, Klamath recognizes that Sterling may have adopted
     different loan, accrual and allowance policies (including loan
     classifications and levels of allowances for losses).  In that regard and
     in general from and after the date of this Agreement to the Effective
     Time, Klamath and Sterling shall consult and cooperate with each other in
     order to formulate the plan of integration for the Merger, including,
     among other things, with respect to conforming immediately prior to the
     Effective Time, based upon such consultation, Klamath's loan, accrual and
     allowance policies to those policies of Sterling to the extent consistent
     with GAAP, provided, however, that no such additional accruals and loss
     allowances will be: (i) required to be made more than two business days
     prior to the Closing Date or (ii) deemed to have a Material Adverse
     Effect upon Klamath if made upon Sterling's written request.

          (b)  Klamath shall use its reasonable best efforts to terminate or
     withdraw from the Klamath MRDP, the Klamath ESOP and all other Plans
     except for the Klamath Stock Option Plan and the Klamath 401(k) Plan, at
     or as soon as reasonably practicable after the Effective Time, in
     accordance with the applicable Plan documents and Laws.  Klamath and
     Sterling shall cooperate in this regard.  Sterling agrees, subject to
     applicable Laws and the Plan documents, to allow any unallocated shares
     of Klamath Common Stock in the Klamath ESOP (following retirement of all
     borrowings of the Klamath ESOP)to be allocated to participants and to
     cause any overfunding to be allocated to participants as earnings.  For
     the period prior to the Effective Time, Klamath and Klamath First Federal
     shall be permitted to make contributions to the Klamath ESOP, payments on
     the Klamath ESOP loan and one additional allocation, in October 2003, to
     the accounts of participants in the Klamath ESOP consistent with past
     practices on the regularly scheduled payment dates.

                                     ARTICLE VI
                               ADDITIONAL AGREEMENTS

     6.1  REGULATORY MATTERS.

          (a)  Upon the execution and delivery of this Agreement, Sterling and
     Klamath shall promptly cause the Registration Statement to be prepared
     and filed with the SEC.  Sterling and Klamath shall use their reasonable
     best efforts to have the Registration Statement declared effective by the
     SEC as soon as possible after the filing thereof.  The parties shall
     cooperate in responding to and considering any questions or comments from
     the SEC staff regarding the information contained in the Registration
     Statement.  If at any time after the Registration Statement is filed with
     the SEC, and prior to the Closing Date, any event relating to Klamath or
     Sterling is discovered by Klamath or Sterling, as applicable, which
     should be set forth in an amendment of, or a supplement to, the
     Registration Statement, the discovering party shall promptly inform the
     other party with all relevant information relating to such event,
     whereupon Sterling shall promptly cause an appropriate amendment to the
     Registration Statement to be filed with the SEC.  Upon the effectiveness
     of such amendment, each of Klamath and Sterling (if prior to the meetings
     of their shareholders pursuant to Section 6.3 hereof) will take all
     necessary action as promptly as practicable to permit an appropriate
     amendment or supplement to be transmitted to their shareholders entitled
     to vote at such meetings.  Sterling shall also use reasonable best
     efforts to obtain all necessary state securities law or "Blue Sky"
     permits and approvals required to carry out the transactions contemplated
     by this Agreement and the Institution Merger Agreement and

                                        27





     Klamath shall furnish all information concerning Klamath and the holders
     of Klamath Common Stock as may be reasonably requested in connection with
     any such action.

          (b)  The parties hereto shall cooperate with each other and use
     their best efforts to promptly prepare and file all necessary
     documentation, to effect all applications, notices, petitions and
     filings, and to obtain as promptly as practicable all permits, consents,
     approvals and authorizations of all third parties and Governmental
     Entities which are necessary or advisable to consummate the transactions
     contemplated by this Agreement (including without limitation the Merger
     and the Institution Merger).  Klamath and Sterling shall have the right
     to review in advance, and to the extent practicable each will consult the
     other on, in each case subject to applicable Laws relating to the
     exchange of information, all the information relating to Klamath
     or Sterling, as the case may be, which appears in any filing made
     with, or written materials submitted to, any third party or any
     Governmental Entity in connection with the transactions contemplated by
     this Agreement.  In addition, counsel to Klamath shall be provided with a
     draft of all regulatory applications prior to their submission and shall
     have a period of five business days within which to review and comment on
     such applications.  In exercising the foregoing right, each of the
     parties hereto shall act reasonably and as promptly as practicable.  The
     parties hereto agree that they will consult with each other with respect
     to the obtaining of all permits, consents, approvals and authorizations
     of all third parties and Governmental Entities necessary or advisable to
     consummate the transactions contemplated by this Agreement and each party
     will keep the other apprised of the status of matters relating to
     consummation of the transactions contemplated herein.

          (c)  Klamath shall furnish Sterling with all information concerning
     Klamath and its directors, officers and shareholders and such other
     matters as may be reasonably necessary or advisable in connection with
     the Registration Statement or any other statement, filing, notice or
     application made by or on behalf of Sterling to any Governmental Entity
     in connection with the Merger or the other transactions contemplated by
     this Agreement.

          (d)  Sterling and Klamath shall promptly advise each other upon
     receiving any communication from any Governmental Entity whose consent or
     approval is required for consummation of the transactions contemplated by
     this Agreement which causes such party to believe that there is a
     reasonable likelihood that any Requisite Regulatory Approval (as defined
     in Section 7.1(c) hereof) will not be obtained or that the receipt of any
     such approval will be materially delayed.

     6.2  ACCESS TO INFORMATION.

          (a)  Upon reasonable notice and subject to applicable Laws relating
     to the exchange of information, each party shall accord to the
     representatives of the other party, access, during normal business hours
     throughout the period prior to the Effective Time, to all of its and its
     Subsidiaries' properties, books, contracts, commitments and records and,
     during such period, each party shall make available to the other party
     (i) a copy of each report, schedule, registration statement and other
     document filed or received by it (including its financial institution
     Subsidiary) during such period pursuant to the requirements of federal
     securities laws or federal or state banking laws and (ii) all other
     information concerning its (including its financial institution
     Subsidiary's) business, properties and personnel as the other party may
     reasonably request.  Sterling shall receive notice of all meetings of
     Klamath and Klamath First Federal's Board of Directors and any committees
     thereof, and of any management committees (in all cases, at least as
     timely as all Klamath and Klamath First Federal, as the case may be,
     representatives to such meetings are required to be provided notice).
     Each party shall provide the other party with true, correct and complete
     copies of all financial and other information relating to the business or
     operations of itself and its Subsidiaries that is provided to directors
     of such party or its Subsidiaries in connection with meetings of their
     Boards of Directors or committees thereof.


                                        28





          (b)  Sterling and Klamath entered into a Confidentiality Agreement
     dated May 13, 2003 (the "Confidentiality Agreement").  The
     Confidentiality Agreement shall remain in effect and apply to the
     information furnished by Sterling and Klamath pursuant to this Section
     6.2.

          (c)  No investigation by either of the parties or their respective
     Representatives shall affect the representations and warranties of the
     other set forth herein.

     6.3  SHAREHOLDERS MEETINGS.

          (a)  Each of Sterling and Klamath shall take all steps necessary to
     duly call, give notice of, convene and hold the Sterling Meeting and the
     Klamath Meeting within 40 days after the Registration Statement becomes
     effective for the purpose of voting upon the adoption or approval of this
     Agreement and the Merger.  The Board of Directors of Sterling shall
     recommend to its shareholders approval of this Agreement, including the
     Merger and the transactions contemplated hereby.  The Board of Directors
     of Klamath shall (i) recommend adoption of this Agreement by the
     shareholders of Klamath and (ii) shall not (x) withdraw, modify or
     qualify in any manner adverse to Sterling such recommendation or (y)
     take any other action or make any other public statement in connection
     with the Klamath Meeting inconsistent with such recommendation
     (collectively, a "Change in Klamath Recommendation"), except as and to
     the extent expressly permitted by Section 6.3(b).

          (b)  Notwithstanding the foregoing, Klamath and its Board of
     Directors shall be permitted to effect a Change in Klamath
     Recommendation, if and only to the extent that:

               (i)  Klamath's Board of Directors, based on the advice of its
          outside counsel, determines in good faith that failure to take such
          action would more likely than not result in a violation of its
          fiduciary duties under applicable Law, and

               (ii) Prior to effecting such Change in Klamath Recommendation:
          (A) Klamath shall have complied in all material respects with
          Section 5.1(e), (B) the Board of Directors of Klamath shall have
          concluded in good faith that such Acquisition Proposal constitutes a
          Superior Proposal after giving effect to all of the adjustments
          which may be offered by Sterling pursuant to clause (D) below, (C)
          Klamath shall notify Sterling, at least five business days in
          advance, of its intention to effect a Change in Klamath
          Recommendation in response to such Superior Proposal, specifying the
          material terms and conditions of any such Superior Proposal and
          furnishing to Sterling a copy of the relevant proposed transaction
          agreements with the party making such Superior Proposal and other
          material documents, and (D) Klamath shall, and shall cause its
          financial and legal advisors to, during the period following
          Klamath's delivery of the notice referred to in clause (C) above,
          negotiate with Sterling in good faith (to the extent Sterling
          desires to negotiate) to make such adjustments in the terms and
          conditions of this Agreement so that such Acquisition Proposal
          ceases to constitute a Superior Proposal.

     6.4  LEGAL CONDITIONS TO MERGER.

     Subject to the terms and conditions of this Agreement, each of Sterling
and Klamath shall use their reasonable best efforts (a) to take, or cause to
be taken, all actions reasonably necessary, proper or advisable to comply
promptly with all legal requirements which may be imposed on such party with
respect to the Merger and to consummate the transactions contemplated by this
Agreement and (b) to obtain (and to cooperate with the other party to obtain)
any consent, authorization, order or approval of, or any exemption by, any
Governmental Entity and any other third party which is required to be obtained
by Klamath or Sterling in connection with the Merger and the other
transactions contemplated by this Agreement.


                                        29





     6.5  STOCK EXCHANGE LISTING.

     Sterling shall use its reasonable best efforts to cause the shares of
Sterling Common Stock to be issued in the Merger and pursuant to options
referred to herein to be approved for quotation on NASDAQ prior to or at the
Effective Time.

     6.6  EMPLOYEES.

          (a)  To the extent permissible under the applicable provisions of
     the Code and ERISA, for purposes of crediting periods of service for
     eligibility to participate and vesting, but not for benefit accrual
     purposes, under employee pension benefit plans (within the meaning of
     ERISA Section 3(2)) maintained by Sterling or a Sterling Subsidiary, as
     applicable, individuals who are employees of Klamath or any Klamath
     Subsidiary at the Effective Time will be credited with periods of service
     with Klamath or the applicable Klamath Subsidiary before the Effective
     Time (including service with any predecessor employer for which service
     credit was given under similar employee benefit plans of Klamath or the
     applicable Klamath Subsidiary) as if such service had been with Sterling
     or a Sterling Subsidiary, as applicable.  Similar credit shall also be
     given by Sterling or a Sterling Subsidiary, as applicable, in calculating
     all other employee benefits for such employees of Klamath or a Klamath
     Subsidiary after the Merger.  Sterling will or will cause its applicable
     Subsidiary to (i) give credit to employees of Klamath and its
     Subsidiaries, with respect to the satisfaction of the waiting periods for
     participation and coverage which are applicable under the welfare benefit
     plans of Sterling or its applicable Subsidiary, equal to the credit that
     any such employee had received as of the Effective Time towards the
     satisfaction of any such limitations and waiting periods under the
     comparable welfare benefit plans of Klamath and its Subsidiaries; (ii)

     applicable Klamath Subsidiary.  Klamath and its Subsidiaries shall cash
     out any unused vacation time accrued but not taken by employees as of the
     Effective Time, and Sterling or its Subsidiaries shall give employees
     credit for prior service for vacation accruals after the Effective Time.

          (b)  Sterling or Sterling Savings Bank shall provide severance
     benefits to those employees of Klamath and its Subsidiaries whose
     employment is involuntarily terminated without cause at or within 365

     receive severance payments under employment or similar agreements) in
     accordance with Sterling's current written severance policy as previously
     delivered to Klamath.

          (c) Sterling or Sterling Savings Bank shall with respect to those
     directors of Klamath who are at least age 65 at the Effective Time,
     determine benefits under the existing Klamath Director Fee Continuation
     Agreements under Section IV thereof to the extent that benefits
     thereunder are greater than the benefits that would be received under
     Section IX thereof.

          (d)  Klamath or Klamath First Federal, as applicable, shall make
     payment of the cash severance amounts provided under the employment
     agreements and the cash-out payments provided under the salary
     continuation agreements (as amended) listed in Schedule 3.12 of the
     Klamath Disclosure Schedule on or before December 31, 2003 but only after

          (e)  Sterling or Sterling Savings Bank shall pay the "Entitled
     Percentage" of the "Monthly Premium Paid by KF" as those terms are used

     6.7  INDEMNIFICATION.

          (a)  In the event of any threatened or actual claim, action, suit,
     proceeding or investigation, whether civil, criminal or administrative,
     in which any person who is now, or has been at any time prior to the date
     of this Agreement, or who becomes prior to the Effective Time, a director
     or officer or employee of Klamath or any Klamath Subsidiary (the
     "Indemnified Parties") is, or is threatened to be, made a party based in
     whole or in part on, or arising in whole or in part out of, or pertaining
     to (i) the fact that he is or was a director, officer or employee of
     Klamath or any Klamath Subsidiary or any of their respective predecessors
     or (ii) this Agreement or any of the transactions contemplated hereby,
     whether in any case asserted or arising before or after the Effective
     Time, the parties hereto agree to cooperate and use their best efforts to
     defend against and respond thereto.  It is understood and agreed that,
     after the Effective Time, Sterling shall indemnify and hold harmless, as
     and to the fullest extent permitted by applicable Law, each such
     Indemnified Party against any losses, claims, damages, liabilities,
     costs, expenses including reasonable attorney's fees and expenses in
     advance of the final disposition of any claim, suit, proceeding or
     investigation to each Indemnified Party to the fullest extent permitted
     by Law (upon receipt of any undertaking required by applicable Law from
     such Indemnified Party to repay such advanced  expenses if it is
     determined by a final and non-appealable judgment of a court of
     competent jurisdiction that such Indemnified Party was not entitled
     to indemnification hereunder), judgments, fines and amounts paid
     in settlement in connection with any such threatened or actual claim,
     action, suit, proceeding or investigation, and in the event of any such
     threatened or actual claim, action, suit, proceeding or investigation
     (whether asserted or arising before or after the Effective Time), the
     Indemnified Parties may retain counsel reasonably satisfactory to
     Sterling; provided, however, that (1) Sterling shall have the right to
     assume the defense thereof and upon such assumption Sterling shall not be
     liable to any Indemnified Party for any legal expenses of other counsel
     or any other expenses subsequently incurred by any Indemnified Party in
     connection with the defense thereof, except that if Sterling elects
     not to assume such defense or counsel for the Indemnified Parties
     reasonably advises the Indemnified Parties that there are issues which
     raise conflicts of interest between Sterling and the Indemnified Parties,
     the Indemnified Parties may retain counsel reasonably satisfactory
     to Sterling, and Sterling shall pay the reasonable fees and expenses of
     such counsel for the Indemnified Parties, (2) Sterling shall be obligated
     pursuant to this paragraph to pay for only one firm of counsel reasonably
     required in each applicable jurisdiction for each Indemnified Party, and
     (3) Sterling shall not be liable for any settlement effected without its
     prior written consent (which consent shall not be unreasonably withheld
     or delayed).  Any Indemnified Party wishing to claim indemnification
     under this Section 6.7, upon learning of any such claim, action, suit,
     proceeding or investigation, shall notify Sterling thereof; provided,
     however, that the failure to so notify shall not affect the obligations
     of Sterling under this Section 6.7 except to the extent such failure to
     notify materially prejudices Sterling.  Sterling's obligations under this
     Section 6.7 shall continue in full force and effect for a period of six
     years from the Effective Time; provided, however, that all rights to
     indemnification in respect of any claim asserted or made within such
     period shall continue until the final disposition of such claim.

          (b)  Sterling shall use commercially reasonable efforts to cause the
     persons serving as officers and directors of Klamath and the Klamath
     Subsidiaries immediately prior to the Effective Time to be covered by a
     directors' and officers' liability insurance policy of substantially the
     same coverage and amounts containing terms and conditions which are
     generally not less advantageous than Klamath's current policy with
     respect to acts or omissions occurring prior to the Effective Time which
     were committed by such officers and directors in their capacity as such
     for a period not less than three years.

                                        31





          (c)  This Section 6.7 shall survive the Effective Time and is
     intended to benefit each indemnified person (each of whom shall be
     entitled to enforce this Section against Sterling).

          (d)  In the event Sterling or any of its successors or assigns (i)
     consolidates with or merges into any person (other than an affiliate) and
     shall not be the continuing or surviving corporation or entity of such
     consolidation or merger, or (ii) transfers all or substantially all of
     its properties and assets to one or more persons (other than affiliates
     as defined in Rule 144 under the Securities Act), then, and in each case,
     proper provision shall be made so that the successors and assigns of
     Sterling assume the obligations set forth in this Section 6.7.

     6.8  SUBSEQUENT INTERIM AND ANNUAL FINANCIAL STATEMENTS.

     As soon as reasonably available, but in no event later than the SEC
filing deadlines, Sterling will deliver to Klamath and Klamath will deliver to
Sterling their respective Exchange Act Reports.

     6.9  ADDITIONAL AGREEMENTS.

     In case at any time after the Effective Time any further action is
necessary or desirable to carry out the purposes of this Agreement, or to vest
the Surviving Corporation or the Surviving Institution with full title to all
properties, assets, rights, approvals, immunities and franchises of any of the
parties to the Merger, or the constituent parties to the Institution Merger,
as the case may be, the proper officers and directors of each party to this
Agreement and Sterling's Subsidiaries and Klamath First Federal shall take all
such necessary action as may be reasonably requested by Sterling.

     6.10 ADVICE OF CHANGES.

     Sterling and Klamath shall promptly advise the other party of any change
or event that, individually or in the aggregate, has had or would be
reasonably certain to have a Material Adverse Effect on it or to cause or
constitute a material breach of any of its representations, warranties or
covenants contained herein.  From time to time prior to the Effective Time,
each party will promptly supplement or amend its disclosure schedule delivered
in connection with the execution of this Agreement to reflect any matter
which, if existing, occurring or known at the date of this Agreement, would
have been required to be set forth or described in such disclosure schedule or
which is necessary to correct any information in such disclosure schedule
which has been rendered inaccurate thereby.  No supplement or amendment to
such disclosure schedule shall have any effect for the purpose of determining
satisfaction of the conditions set forth in Sections 7.2(a) or 7.3(a) hereof,
as the case may be, or the compliance by Klamath or Sterling, as the case may
be, with the respective covenants set forth in Sections 5.1 and 5.2 hereof.

     6.11 CURRENT INFORMATION.

     During the period from the date of this Agreement to the Effective Time,
Klamath will cause one or more of its designated representatives to confer on
a regular and frequent basis (not less than monthly) with representatives of
Sterling and to report the general status of the ongoing operations of
Klamath.  Each party will promptly notify the other party of any material
change in the normal course of business or in the operation of the properties
of itself or any of its Subsidiaries and of any governmental complaints,
investigations or hearings (or communications indicating that the same may be
contemplated), or the institution or the threat of litigation involving itself
or any of its Subsidiaries, and will keep the other party fully informed of
such events.

     6.12 EXECUTION AND AUTHORIZATION OF INSTITUTION MERGER
          AGREEMENT.

     Prior to the Effective Time, (a) Sterling and Klamath shall each approve
the Institution Merger Agreement as the sole shareholder of Sterling Savings

and Sterling Savings Bank shall execute and deliver the Institution Merger
Agreement.

     6.13 CHANGE IN STRUCTURE.

     Sterling may elect to modify the structure of the transactions
contemplated by this Agreement as noted herein so long as (i) there are no
adverse tax consequences to the Klamath shareholders as a result of such
modification, (ii) the consideration to be paid to the Klamath shareholders
under this Agreement is not thereby changed or reduced in amount, and (iii)
such modification will not delay or jeopardize receipt of any Requisite
Regulatory Approvals.  In the event that the structure of the Merger is
modified pursuant to this Section 6.13, the parties agree to modify this
Agreement and the various exhibits hereto to reflect such revised structure.
In such event, Sterling shall prepare appropriate amendments to this Agreement
and the exhibits hereto for execution by the parties hereto.  Klamath agrees
to cooperate fully with Sterling to effect such amendments.

     6.14 TRANSACTION EXPENSES OF KLAMATH.

     As promptly as practicable after the execution of this Agreement, Klamath

     each person that, to the best of its knowledge, is or is reasonably
     likely to be, as of the date of the Klamath Meeting called pursuant to

          (b)  Klamath shall use its reasonable best efforts to cause each
     person who may be deemed to be a Klamath Affiliate to execute and deliver

     The respective obligation of each party to effect the Merger shall be
subject to the satisfaction at or prior to the Effective Time of the following
conditions:

          (a)  Shareholder Approvals.  This Agreement and the Merger shall
     have been approved or adopted by the requisite vote of the Sterling and
     Klamath shareholders.

          (b)  Stock Exchange Listing.  The shares of Sterling Common Stock
     which shall be issued in the Merger upon consummation of the Merger shall
     have been authorized for quotation on NASDAQ (or such other exchange on

          (c)  Other Approvals.  All regulatory approvals required to
     consummate the transactions contemplated hereby shall have been obtained
     and shall remain in full force and effect and all statutory waiting
     periods in respect thereof shall have expired (all such approvals and the
     expiration of all such waiting periods being referred to herein as the
     "Requisite Regulatory Approvals").

                                        33





          (d)  Registration Statement.  The Registration Statement shall have
     become effective under the Securities Act, and no stop order suspending
     the effectiveness of the Registration Statement shall have been issued
     and no proceedings for that purpose shall have been initiated or
     threatened by the SEC.

          (e)  No Injunctions or Restraints; Illegality.  No order, injunction
     or decree issued by any court or agency of competent jurisdiction or
     other legal restraint or prohibition (an "Injunction") preventing the
     consummation of the Merger or any of the other transactions contemplated
     by this Agreement shall be in effect.  No statute, rule, regulation,
     order, Injunction or decree shall have been enacted, entered, promulgated
     or enforced by any Governmental Entity which prohibits, restricts or
     makes illegal consummation of the Merger.  No proceeding initiated by any
     Governmental Entity seeking an Injunction shall be pending.

          (f)  Federal Tax Opinion.  Sterling shall have received an opinion
     from Witherspoon, Kelley, Davenport & Toole, P.S., counsel to Sterling,
     and Klamath shall have received an opinion from Silver, Freedman & Taff,
     LLP, special counsel to Klamath, in form and substance reasonably
     satisfactory to Sterling and Klamath, respectively, dated the date of the
     Effective Time, in each case, substantially to the effect that on the
     basis of facts, representations, and assumptions set forth in such
     opinion  which are consistent with the state of facts existing at the
     Effective Time, the Merger will be treated for federal income tax
     purposes as a reorganization within the meaning of Section 368(a)
     of the Code and each of Sterling and Klamath will be a party to the
     reorganization with the meaning of Section 368(b) of the Code and that,
     accordingly, for federal income tax purposes, (i) no gain or loss
     will be recognized by Sterling or Klamath as a result of the Merger,
     (ii) no gain or loss will be recognized by the shareholders of Klamath
     who exchange all of their Klamath Common Stock solely for Sterling Common
     Stock pursuant to the Merger (except with respect to cash received in
     lieu of a fractional share interest in Sterling Common Stock), and (iii)
     the aggregate tax basis of the Sterling Common Stock received by
     shareholders who exchange all of their Klamath Common Stock solely for
     Sterling Common Stock pursuant to the Merger will be the same as the
     aggregate tax basis of the Klamath Common Stock surrendered in exchange
     therefore (reduced by any amount allocable to a fractional share interest
     for which cash is received).  In rendering such opinion, such counsel
     shall require and, to the extent such counsel deems necessary or
     appropriate, may rely upon representations and covenants, including those
     contained in certificates of officers of Klamath, Sterling, their
     respective affiliates and others.

     in the aggregate, would have a Material Adverse Effect on Klamath.
     Sterling shall have received a certificate signed on behalf of Klamath by
     each of the President and Chief Executive Officer and the Chief Financial
     Officer of Klamath to the foregoing effect.

          (b)  Performance of Covenants and Agreements of Klamath.  Klamath

     warranties of Sterling set forth in this Agreement shall be true and
     correct as of the date of this Agreement and as of the Closing Date as
     though made on and as of the Closing Date; provided, however, that for
     purposes of this paragraph, such representations and warranties shall be

     Governmental Entity of competent jurisdiction shall have issued a final
     nonappealable order enjoining or otherwise prohibiting the consummation

     party set forth herein;

          (c)  by either Sterling or Klamath if the Merger shall not have been

     agreements of such party set forth herein;

                                       35





          (d)  by either Sterling or Klamath (provided that the terminating
     party is not then in material breach of any representation, warranty,
     covenant or other agreement contained herein) if the other party shall
     have breached (i) any of the covenants or agreements made by such other

          (f)  by either Sterling or Klamath if: (i) the Board of Directors of
     Klamath shall have failed to recommend to its shareholders the approval
     of the Merger, or shall have made, or publicly announced its intention to
     make, a Change in Klamath Recommendation, or (ii) Klamath shall have
     breached the terms of Section 5.1(e) hereof in any respect adverse to
     Sterling;

          (g)  by Sterling if a tender offer or exchange offer for 25% or more
     of the outstanding shares of Klamath Common Stock is commenced (other
     than by Sterling or a Subsidiary thereof), and the Board of Directors of
     Klamath recommends that the shareholders of Klamath tender their shares

          (h)  by Klamath, upon its written notice to Sterling within the two
     business days following the Determination Date (as defined below), in the
     event that:

               (1)  The failure of the Closing to occur is not due to a

          covenants or other agreements contained herein;

               (3)  (a) the number obtained by dividing the Sterling
          Determination Price by $24.15 is less than (b) the number obtained
          by dividing the Final Index Price (as defined below) by the Initial
          Index Price (as defined below) and then multiplying the quotient in
          this clause 3(b) by 0.85.

          Final Index Price and the Initial Index Price. The 20 financial
          institution holding companies and the weights attributed to them are
          listed on Exhibit F.

               "Initial Index Price" means the sum of each per share closing
          price of the common stock of each company comprising the Index Group
          multiplied by the applicable weighting, as such prices are reported
          on the consolidated transactions reporting system for the market or
          exchange on which such common stock principally traded on June 13,
          2003.  (See Exhibit F.)

     If Sterling declares or effects a stock dividend, reclassification,
recapitalization, split-up, combination, exchange of shares or similar
transaction between the date of this Agreement and the Determination Date, the
prices for the Sterling Common Stock shall be appropriately adjusted for the
purposes of applying this Section 8.1(h).

     If Klamath elects to exercise its termination right pursuant to this
Section 8.1(h), it shall give written notice to Sterling within two business
days after the Determination Date, such termination will be effective on the
third business day after the giving of such notice (the "Effective Termination
Date"); provided that within two business days after Sterling's receipt of
such notice, Sterling shall have the option to increase the consideration to
be received by holders of Klamath Common Stock hereunder by multiplying the
Exchange Ratio by the Exchange Ratio Adjustment Factor (as defined below) to
create the Adjusted Exchange Ratio (as defined below) such that Klamath would
not be entitled to terminate this Agreement pursuant to this Section 8.1(h).
If Sterling so elects, it shall timely give written notice to Klamath of such
election and the Adjusted Exchange Ratio whereupon no termination shall be
deemed to have occurred pursuant to Section 8.1(h) and this Agreement shall
remain in full force and effect in accordance with its terms (except as the
Exchange Ratio shall have been so modified).

     "Exchange Ratio Adjustment Factor" means the lessor of:

          1)   $20.53 divided by the Sterling Determination Price; or

          2)   (a)  the number obtained by dividing the Final Index Price by
                    the Initial Index Price and multiplying this quotient by
                    0.85

                                      divided by

               (b)  the number obtained by dividing the Sterling Determination
                    Price by $24.15.

     "Adjusted Exchange Ratio" means the Exchange Ratio multiplied by the
Exchange Ratio Adjustment Factor.

          (i)  by Klamath if the Board of Directors of Sterling shall have
     failed to recommend to its shareholders the approval of the Merger or
     withdrawn, modified or qualified such recommendation in any manner
     adverse to Klamath.

     8.2  EFFECT OF TERMINATION.

          (a)  In the event of termination of this Agreement by either
     Sterling or Klamath as provided in Section 8.1, this Agreement shall
     forthwith become void and have no effect except: (i) Sections 6.2(c),
     8.2, and 9.3 shall survive any termination of this Agreement, and (ii)
     notwithstanding anything to the contrary contained in this Agreement,
     except as provided in the second and third sentences of Section 8.2(b),
     no party shall be relieved or released  from any liabilities or damages
     arising out of its willful or intentional breach of any provision of this
     Agreement.

                                        37





          (b)  Klamath shall pay Sterling a fee (the "Klamath Termination
     Fee") if this Agreement is terminated under certain conditions.  If
     this Agreement is terminated pursuant to Sections 8.1(f) or 8.1(g)
     the Klamath Termination Fee shall be $6 million and the receipt thereof
     by Sterling in accordance with the terms hereof shall be Sterling's sole
     and exclusive remedy for a termination of this Agreement pursuant to
     Sections 8.1(f) or 8.1(g).  If Klamath terminates this Agreement pursuant
     to Section 8.1(i), Sterling shall pay Klamath a fee of $1.5 million (the
     "Sterling Termination Fee"), which shall be Klamath's sole and exclusive
     remedy for a termination of this Agreement pursuant to Section 8.1(i).
     If Sterling terminates this Agreement pursuant to Section 8.1(d) the
Klamath Termination Fee shall be $1.5 million, provided that if within 18
     months after termination Klamath or any of its Subsidiaries enters into a
     definitive agreement with respect to, or consummates, an Acquisition
     Proposal, the Klamath Termination Fee shall be $6 million (net of any
     prior payment of the said $1.5 million).

          (c)  The Klamath Termination Fee or the Sterling Termination Fee, as
     the case may be, shall be paid within two business days following a
     termination referred to in Sections 8.1(i) and 8.2(b), as applicable, and
     shall be made by wire transfer of immediately available funds to an
     account designated by the party entitled to receive such fee.

          (d)  Sterling and Klamath agree that the agreements contained in
     this Section 8 are an integral part of the transactions contemplated by
     this Agreement, that without such agreements they would not have entered
     into this Agreement and that neither the Klamath Termination Fee nor the
     Sterling Termination Fee constitute a penalty.  If a party hereto fails
     to pay the amounts due under Section 8.2(b) within the time periods
     specified in Section 8.2(c), that party shall pay the costs and expenses
     (including reasonable legal fees and expenses) incurred by the other
     party in connection with any action, including the filing of any lawsuit,
     taken to collect payment of such amounts, together with interest on the
     amount of such unpaid amounts at the prime lending rate as published in
     the Wall Street Journal from the date such amounts were required to be
     paid until the date of actual payment.

     8.3  AMENDMENT.

     Subject to compliance with applicable Law, this Agreement may be amended
by the parties hereto, by action taken or authorized by their respective
Boards of Directors, at any time before or after approval of the matters
presented in connection with the Merger by the shareholders of Klamath;
provided, however, that after any approval of the transactions contemplated by
this Agreement by Klamath's shareholders, there may not be, without further
approval of such shareholders, any amendment of this Agreement which reduces
the amount or changes the form of the consideration to be delivered to Klamath
shareholders hereunder other than as contemplated by this Agreement.  This
Agreement may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto.

     8.4  EXTENSION; WAIVER.

     At any time prior to the Effective Time, the parties hereto, by action
taken or authorized by their respective Boards of Directors, may, to the
extent legally allowed, (a) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (b) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto, and (c) waive compliance with any of the
agreements or conditions contained herein.  Any agreement on the part of a
party hereto to any such extension or waiver shall be valid only if set forth
in a written instrument signed on behalf of such party, but such extension or
waiver or failure to insist on strict compliance with an obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

                                        38

                         STERLING FINANCIAL CORPORATION
                             OF SPOKANE, WASHINGTON,
                    ANNOUNCES DEFINITIVE AGREEMENT TO ACQUIRE
                          KLAMATH FIRST BANCORP, INC.

Spokane, Washington and Klamath Falls, Oregon July 15, 2003 Sterling Financial
Corporation (NASDAQ: STSA) and Klamath First Bancorp, Inc. (NASDAQ: KFBI)
announced today that they have signed a definitive agreement for the merger of
Klamath First Bancorp, Inc. with and into Sterling Financial Corporation.

The transaction, which is valued at approximately $147 million, is expected to
close in the first quarter of 2004, pending shareholder and regulatory
approval, and to be accretive to Sterling's earnings per share in 2004.

Under the terms of the merger agreement, which has been unanimously approved
by the Boards of Directors of both companies, each share of Klamath common
stock will be converted into 0.77 shares of Sterling common stock subject to
certain conditions. Based upon the closing price for Sterling on July 14 of
$26.55 per share, the consideration is equivalent to $20.44 per share of
Klamath common stock. The parties have agreed to pay termination fees in the
event the merger agreement is terminated under certain conditions. The
exchange of shares is expected to be tax-free to the Klamath shareholders.

Based upon balance sheet data as of March 31, 2003, the combined company will
have approximately $5.3 billion in total assets, deposits of approximately
$3.4 billion, and shareholders' equity of approximately $388 million. Based on
yesterday's closing price, the combined company will have a market
capitalization of approximately $535 million.

Sterling's Chairman and Chief Executive Officer, Harold B. Gilkey, commented,
"We are very pleased to welcome the employees, customers and investors of
Klamath into the Sterling family. This merger is consistent with our
previously stated growth plans to become the leading community bank in the
region."

With the increase to approximately 143 branches serving Oregon, Washington,
Idaho, and Montana, Sterling strengthens its position as a leading regional
community bank and gives it the ability to extend its "Hometown Helpful"
philosophy throughout communities in the region.

"The merger with Klamath is a perfect fit for Sterling," said Mr. Gilkey. "In
addition to the financial aspects, Sterling and Klamath match up very well
culturally. As a leading regional community bank we'll be able to build a bank
for all of Oregon, a bank that offers the same products and services of a
large bank while retaining the feel of a hometown bank."

Mr. Gilkey expressed confidence that Klamath would be smoothly integrated into
Sterling. "Our two institutions have complementary financial, organizational
and philosophical aspects. Sterling has averaged one acquisition per year
since 1998 and has successfully integrated every merged institution into
Sterling. From our acquisition of 33 bank branches and related operations to
the recent addition of five Empire branches in Montana, our back office is
well-prepared for this merger," said Mr. Gilkey. "When two community banks
join forces, the transition tends to be smooth since both institutions are
used to operating with the focus on understanding the individual communities
in which they do business."
                                       1





According to Kermit K. Houser, President and CEO of Klamath, "This combination
of companies is positive in every way. It accelerates our mutual desire to
provide extensive coverage in the Northwest, as our existing geographic
footprints are a perfect fit. Klamath's strong deposit base supports
Sterling's strong loan growth and the combined banking products and offices
add additional business options and customer convenience. The larger
organization also provides numerous opportunities for Klamath First employees
and our shareholders are receiving a premium over our stock price today and
will have an opportunity for future growth with the larger company."

Rodney Murray, Chairman of Klamath First Bancorp, Inc. commented, "We are very
pleased to be joining Sterling Financial Corporation. Becoming a part of a
leading regional community bank will give Klamath the opportunity to
accelerate our business plan and better serve the customers and communities we
have served for nearly 70 years. I am very pleased that our customers will
continue to receive the personalized service from our customer service staff,
but at the same time will have access to a much wider array of products and
services. In addition, Sterling's community-banking culture, local
decision-making, strong commitment to employees and involvement in local
communities carries on the traditions that Klamath has taken such pride in for
so many years. "

According to Gilkey, "Sterling will continue local decision-making in Oregon.
This will allow us to continue to deliver on our promise to customers of
prompt, professional responses to their banking needs and our history of
community involvement in these Oregon communities. Sterling intends to form an
Oregon-area advisory board comprised of current Klamath board members to
facilitate Sterling's further expansion in Oregon. In addition, Sterling will
be adding one board position at the holding company and two seats on the
Sterling Savings Bank board. Klamath board members will be asked to fill these
positions."

Commenting further, Mr. Gilkey, stated, "This transaction is a win-win for the
shareholders of both companies. The access to capital and other resources
gives Sterling the opportunity to continue its regional growth. Additionally,
the transaction reflects Sterling's long-term strategy of concentrating on its
core businesses, including our ability to diversify loan portfolio
opportunities across the region. Sterling welcomes and looks forward to a
long-term opportunity for achievements and success with this acquisition."
