The obligations of each Underwriter hereunder are subject to the following conditions: (a) Notification that the Registration Statement has become effective shall be received by the Representatives not later than 5:00 p.m., New York City time, on the date of this Agreement or at such later date and time as shall be consented to in writing by the Representatives and all filings required by Rule 424 and Rule 430A of the Rules and Regulations shall have been made, and the Shares shall be qualified or registered for sale in such jurisdictions as the Representatives shall request, except where the failure to qualify or register Shares would not, in the reasonable judgment of the Representatives, have a material adverse effect on its ability to market the Shares. (b) (i) No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall be pending or threatened by the Commission, (ii) no order suspending the effectiveness of the Registration Statement or the qualification or registration of the Shares under the securities or Blue Sky laws of any jurisdiction shall be in effect, and no proceeding for such purpose shall be pending before or threatened or contemplated by the authorities of any such jurisdiction, except where the failure to qualify or register Shares in such jurisdiction would not, in the reasonable judgment of the Representatives, have a material adverse effect on its ability to market the Shares, (iii) any request for additional information on the part of the staff of the Commission or any such authorities shall have been complied with to the satisfaction of the staff of the Commission or such authorities and (iv) after the date hereof no amendment or supplement to the Registration Statement or the Prospectus shall have been filed unless a copy thereof was first submitted to the Representatives and the Representatives do not object thereto in good faith, and the Representatives shall have received certificates, dated the Closing Date and the Option Closing Date and signed by the Chief Executive Officer or the Chairman of the Board of Directors of the Company and the Chief Financial Officer of the Company (who may, as to proceedings threatened, rely upon the best of their information and belief) to the effect of clauses (i), (ii) and (iii). (c) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, (i) there shall not have been a material adverse change in the general affairs, business, business prospects, properties, management, condition (financial or other) or results of operations of the Company, whether or not arising from transactions in the ordinary course of business, in each case other than as set forth in the Registration Statement and the Prospectus and (ii) the Company shall not have sustained any material loss or interference with its business or properties from fire, explosion, flood or other casualty, whether or not covered by insurance, or from any labor dispute or any court or legislative or other governmental order or decree, that is not set forth in the Registration Statement and the Prospectus, if in the reasonable judgment of the Representatives any such development makes it impracticable or inadvisable to consummate the sale and delivery of the Shares by the Underwriters at the public offering price. 14 (d) Since the respective dates as of which information is given in the Registration Statement and the Prospectus, there shall have been no litigation or other proceeding instituted against the Company or any of its officers or directors in their capacities as such, before or by any federal, state or local court, commission, regulatory body, administrative agency or other governmental body, domestic or foreign, in which litigation or proceeding an unfavorable ruling, decision or finding would materially and adversely affect the business, business prospects, properties, management, condition (financial or other) or results of operations of the Company. (e) Each of the representations and warranties of the Company contained herein shall be true and correct in all material respects at the Closing Date and, with respect to the Option Shares, at the Option Closing Date, and all covenants and agreements contained herein to be performed on the part of the Company and all conditions contained herein to be fulfilled or complied with by the Company at or prior to the Closing Date and, with respect to the Option Shares, at or prior to the Option Closing Date, shall have been duly performed, fulfilled or complied with. (f) The Representatives shall have received on the Closing Date or the Option Closing Date, as the case may be, the opinion of Stoel Rives LLP, counsel for the Company, dated the Closing Date, or the Option Closing Date, as the case may be, addressed to the Underwriters (and stating that it may be relied upon by counsel to the Underwriters) to the effect that: (i) The Company has been duly incorporated and is an active corporation under the laws of the State of Washington, and the Company is duly qualified to transact business as a foreign corporation in Oregon.

(iii) The Company has authorized, issued and outstanding capital stock as set forth under the caption "Capitalization" in the Prospectus; the issued and outstanding shares of the Company's Common Stock have been duly authorized and validly issued, are fully paid and non-assessable, and to the actual knowledge of such counsel were not issued in violation of or subject to any preemptive rights or other rights to subscribe for or purchase securities. (iv) The Shares have been duly authorized by all necessary corporate action of the Company and when issued and paid for as 15 contemplated by this Agreement will be validly issued, fully paid and non-assessable; no preemptive rights of shareholders exist under any statute or,to the actual knowledge of such counsel, otherwise with respect to any of the Shares or the issue or sale thereof; the Shares conform to the description thereof contained in the Registration Statement; and the certificates for the Shares comply as to form with the requirements of Washington law. (v) The Representatives' Warrants have been authorized for issuance to the Representatives and will, when issued, possess rights, privileges, and characteristics as represented in the most recent form of Representatives' Warrants filed as an exhibit to the Registration Statement; the Common Stock to be issued upon exercise of the Representatives' Warrants, when issued and delivered against payment therefor in accordance with the terms of the Representatives' Warrants, will be duly and validly issued, fully paid, non-assessable and, to the actual knowledge of such counsel, free of preemptive rights, and all corporate action required to be taken for the authorization and issuance of the Representatives' Warrants, and the securities to be issued upon their exercise, has been validly and sufficiently taken. (vi) Except as described in the Prospectus, to the actual knowledge of such counsel, there are no (A) outstanding securities or obligations of the Company convertible or exchangeable into or evidencing the right to purchase or subscribe for, any shares of capital stock of the Company or (B) outstanding or authorized options, warrants or rights of any character obligating the Company to issue any shares of its capital stock or any securities convertible into or exchangeable for or evidencing the right to purchase or subscribe for any capital stock of the Company, and, except as described in the Prospectus, to the actual knowledge of such counsel, no holder of any securities of the Company or any other person has the right, contractual or otherwise, which has not been satisfied or effectively waived, to cause the Company to sell or otherwise issue to them, or to permit them to underwrite the sale of, any of the Shares or the right to have any shares of Common Stock or other securities of the Company included in the Registration Statement or the right, as a result of the filing of the Registration Statement, to require registration under the Act of any shares of Common Stock or other securities of the Company. (vii) The Registration Statement has been declared effective under the Act and, to the actual knowledge of such counsel, no stop order proceedings with respect thereto have been instituted or are pending or threatened under the Act. (viii) The Registration Statement, the Prospectus and each amendment or supplement thereto comply as to form in all material respects 16 with the requirements of the Act and the Rules and Regulations (except that such counsel need not express an opinion as to the financial statements, financial data and related schedules thereto). (ix) Such counsel does not know of any contracts or documents required to be filed as exhibits to the Registration Statement or described in the Registration Statement or the Prospectus that are not so filed or described as required, and such contracts and documents as are summarized in the Registration Statement or the Prospectus are fairly summarized in all material respects. (x) The statements, other than statements of the Company's belief, under the captions "Risk Factors--Dependence on Affiliated Professional Corporations," "Risk Factors--Government Regulation," "Risk Factors--Shares Eligible for Future Sale," "Risk Factors--Possible Adverse Effect of Issuance of Preferred Stock; Potential Antitakeover Effect of Washington Law," "Business--Support Services Agreements," "Business--Government Regulation," "Business--Service Mark," "Management--1993 Stock Incentive Plan," "Certain Transactions," "Description of Capital Stock," and "Shares Eligible for Future Sale" in the Prospectus and in Item 24 of the Registration Statement, insofar as such statements constitute a summary of documents referred to therein or matters of law, fairly summarize in all material respects the information called for with respect to such documents and matters. (xi) To the actual knowledge of such counsel, no legal or governmental proceedings are pending or threatened to which the Company or any of the Professional Corporations is a party or to which the property of the Company or any of the Professional Corporations is subject that are required to be described in the Registration Statement or the Prospectus and are not described therein. (xii) The Support Services Agreements, dated as of January 1, 1996, between the Company and the Professional Corporations have each been duly authorized, executed and delivered by the Company and each of the Support Services Agreements constitute the valid and legally binding obligation of each of the other parties thereto and are enforceable in accordance with their terms, except as enforceability may be limited by legal uncertainties disclosed in the Prospectus and by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity. 17 (xiii) This Agreement has been duly and validly authorized by all necessary corporate action of the Company, and this Agreement has been duly and validly executed and delivered by and on behalf of the Company and is a valid, binding and enforceable agreement of the Company enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity and except as to those provisions relating to indemnity or contribution for liabilities arising under the Act as to which no opinion need be expressed. (xiv) The issuance, offering and sale of the Shares to the Underwriters by the Company pursuant to this Agreement, the compliance by the Company with the other provisions of this Agreement and the consummation of the other transactions herein contemplated do not (A) require the consent, approval, authorization, registration or qualification of or with any governmental authority, except such as have been obtained and such as may be required under state securities or Blue Sky laws, or (B) conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under, any indenture, mortgage, deed of trust, lease or other agreement or instrument known to such counsel to which the Company is a party or by which the Company or any of its properties are bound, or the Restated Articles of Incorporation or bylaws of the Company, or any statute or any judgment, decree, order, rule or regulation of any court or other governmental authority or any arbitrator known to such counsel and applicable to the Company. (xv) The Company is not, and will not become, as a result of the consummation of the transactions contemplated by this Agreement and application of the net proceeds therefrom as described in the Prospectus, required to register as an investment company under the 1940 Act. In rendering such opinion, counsel for the Company may rely as to matters governed by the laws of states other than Washington or federal laws on local counsel in such jurisdictions, provided, however, that in each case counsel for the Company shall state that they believe that they and the Underwriters are justified in relying on such other counsel. In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel which leads it to believe that (i) the Registration Statement, at the time it became effective under the Act (but after giving effect to any modifications incorporated therein pursuant to Rule 430A of the Rules and Regulations) and as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) the 18 Prospectus, or any supplement thereto, on the date it was filed pursuant to the Rules and Regulations and as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to financial statements, financial data and statistical information therein). In rendering such opinion, such counsel (i) may state that the opinion is governed by, and shall be interpreted in accordance with, the Legal Opinion Accord (the "Accord") of the ABA Section of Business Law (1991) and that the opinions set forth in clause (i) above are qualified by the General Qualifications (as defined in the Accord), and (ii) shall state that "actual knowledge" shall for the purposes of the opinion have the meaning set forth in the Accord, as supplemented by such counsel's inquiry of the Chief Executive Officer and the Chief Financial Officer of the Company. (g) The Representatives shall have received from Tonkon, Torp, Galen, Marmaduke & Booth, counsel for the Underwriters, an opinion dated the Closing Date or the Option Closing Date, as the case may be, substantially to the effect specified in subparagraphs (vii) and (viii) of Paragraph (f) of this Section 5 and that the Company is a duly organized and validly existing corporation under the laws of the State of Washington. In rendering such opinion, counsel for the Underwriters may rely as to all matters governed by the laws of states other than the State of Oregon or federal laws on the opinion of counsel referred to in Paragraph (f) of this Section 5. In addition to the matters set forth above, such opinion shall also include a statement to the effect that nothing has come to the attention of such counsel that leads them to believe that (i) the Registration Statement, or any amendment thereto, as of the time it became effective under the Act (but after giving effect to any modifications incorporated therein pursuant to Rule 430A of the Rules and Regulations) as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (ii) the Prospectus, or any supplement thereto, on the date it was filed pursuant to the Rules and Regulations and as of the Closing Date or the Option Closing Date, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to financial statements, schedules and statistical information therein). (h) The Representatives shall have received at or prior to the Closing Date from counsel for the Underwriters a memorandum or summary, in form and substance satisfactory to the Representatives, with respect to the qualification for offering and sale by the Underwriters of the Shares under the state securities or Blue Sky laws of such jurisdictions as the Representatives may reasonably have designated to the Company. 19 (i) Concurrently with the execution and delivery of this Agreement, the Accountants shall have furnished to the Representatives a letter or letters, dated the date of its or their delivery, addressed to the Representatives and in form and substance satisfactory to the Representatives, confirming that they are independent accountants with respect to the Company as required by the Act and the Rules and Regulations and with respect to certain financial and other statistical and numerical information contained in the Registration Statement. At the Closing Date and, as to the Option Shares, the Option Closing Date, the Accountants shall have furnished to the Representatives a letter or letters, dated the date of its or their delivery, that shall confirm, on the basis of a review in accordance with the procedures set forth in the letter or letters from the Accountants, that nothing has come to their attention during the period from the date of the letter referred to in the prior sentence to a date (specified in the letter) not more than five days prior to the Closing Date and the Option Closing Date, as the case may be, that would require any change in their letter dated the date hereof if it were required to be dated and delivered at the Closing Date and the Option Closing Date. (j) Concurrently with the execution and delivery of this Agreement and at the Closing Date and, as to the Option Shares, the Option Closing Date, there shall be furnished to the Representatives an accurate certificate of the Company, dated the date of its delivery, signed by each of the Chief Executive Officer and the Chief Financial Officer of the Company on behalf of the Company, in form and substance satisfactory to the Representatives, to the effect that: (i) Each signer of such certificate has carefully examined the Registration Statement and the Prospectus on behalf of the Company. As of the date of such certificate, such documents are true and correct in all material respects and do not omit to state a material fact required to be stated therein or necessary in order to make the statements therein not untrue or misleading. In the case of the certificate delivered at the Closing Date and the Option Closing Date, since the Effective Date no event has occurred as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein not untrue or misleading in any material respect. (ii) Each of the representations and warranties of the Company contained in this Agreement were, when originally made, and are, at the time such certificate is delivered, true and correct in all material respects. (iii) Each of the covenants required to be performed by the Company herein on or prior to the date of such certificate has been duly, timely and fully performed, and each condition herein required to be satisfied or fulfilled on or prior to the date of such certificate has been duly, timely and fully satisfied or fulfilled. 20 (k) On or prior to the Closing Date, the Representatives shall have received the executed agreements referred to in Section 4(m). (l) Prior to the Closing Date, the Shares shall have been duly authorized for quotation on the Nasdaq SmallCap Market upon notice of issuance. (m) The Company shall have furnished to the Representatives such certificates, in addition to those specifically mentioned herein, as the Representatives may have reasonably requested as to the accuracy and completeness at the Closing Date and the Option Closing Date of any statement in the Registration Statement or the Prospectus, as to the accuracy at the Closing Date and the Option Closing Date of the representations and warranties of the Company herein, as to the performance by the Company of its obligations hereunder, or as to the fulfillment of the conditions concurrent and precedent to the obligations hereunder of the Representatives. 6. Indemnification. (a) The Company will indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person, if any, who controls each Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted) to which they, or any of them, may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or any amendment or supplement to the Registration Statement or the Prospectus, or the omission or alleged omission to state in such document a material fact required to be stated in it or necessary to make the statements in it not misleading in light of the circumstances in which they were made, provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person by an Underwriter and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of any Underwriter expressly for inclusion in the Registration Statement, the Preliminary Prospectus or the Prospectus, and provided further, however, that the Company will not be liable to any Underwriter, the directors, officers, employees or agents of such Underwriter or any person controlling such Underwriter with respect to any loss, claim, liability, expense, charge or damage arising out of or based on any untrue statement or omission or alleged untrue statement or omission or alleged omission to state a material fact in the Preliminary Prospectus that is corrected in the Prospectus if the person asserting any such loss, claim, liability, charge or damage purchased Shares from such Underwriter but was not 21 sent or given a copy of the Prospectus at or prior to the written confirmation of the sale of such Shares to such person. This indemnity agreement will be in addition to any liability that the Company might otherwise have. (b) Each Underwriter will indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the foregoing indemnity from the Company to each Underwriter, but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of such Underwriter expressly for use in the Registration Statement, the Preliminary Prospectus or the Prospectus. The Company acknowledges that the statements set forth in the last paragraph of the outside front cover page of the Prospectus and under the heading "Underwriting" in the Preliminary Prospectus and the Prospectus constitute the only information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of the Underwriters expressly for inclusion in the Registration Statement, the Preliminary Prospectus or the Prospectus. This indemnity will be in addition to any liability that each Underwriter might otherwise have. (c) Any party that proposes to assert the right to be indemnified under this Section 6 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party under this Section 6, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify any such indemnifying party will not relieve it from any liability that it may have to any indemnified party under the foregoing provisions of this Section unless, and only to the extent that, such omission results in the loss of substantive rights or defenses by the indemnifying party. If such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in 22 addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (iv) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly as they are incurred. Any indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld). (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 6 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company, or the Underwriters, the Company, and the Underwriters, will contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriters, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company or one or more of the Underwriters may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Underwriters. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as the total net proceeds from the Offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the outside front cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company and the Underwriters, with respect to the statements or omissions that resulted in such loss, claim, liability, expenses or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such Offering. Such relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Representatives on behalf of the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were to be determined by pro rata 23 allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 6(d) shall be deemed to include, for purposes of this Section 6(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts received by it and (ii) no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute as provided in this Section 6(d) are several in proportion to their respective underwriting obligations and not joint. For purposes of this Section 6(d), any person who controls a party to this Agreement within the meaning of the Act will have the same rights to contribution as that party, and each director and officer of the Company who signed the Registration Statement will have the same rights to contribution as the Company, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against any such party in respect of which a claim for contribution may be made under this Section 6(d), will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 6(d). No party will be liable for contribution with respect to any action or claim settled without its consent (which consent will not be unreasonably withheld). (e) The indemnity and contribution agreements contained in this Section 6 and the representations and warranties of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriters or the Company, (ii) acceptance of any of the Shares and payment therefor or (iii) any termination of this Agreement. 7. Termination. The obligations of the several Underwriters under this Agreement may be terminated at any time on or prior to the Closing Date (or, with respect to the Option Shares, on or prior to the Option Closing Date) by notice to the Company from the Representatives, without liability on the part of any Underwriter to the Company if, prior to delivery and payment for the Shares, as the case may be, (a) trading in any of the equity securities of the Company shall have been suspended by the Commission or by the Nasdaq SmallCap Market (b) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange or by order of the Commission or any court or other governmental authority, (c) a general banking moratorium shall have been declared by either federal or New York State authorities or (d) in the reasonable opinion of the Representatives, there is 24 any material adverse change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States or any outbreak or material escalation of hostilities or other calamity or crisis shall have occurred, the effect of which is such as to make it, in the reasonable judgment of the Representatives, impracticable to market the Shares. 8. Substitution of Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase any of the Firm Shares that it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of Firm Shares, the other Underwriters shall be obligated, severally, to purchase the Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase in the proportions that the number of Firm Shares that they have respectively agreed to purchase pursuant to Section 1 bears to the aggregate number of Firm Shares that all such nondefaulting Underwriters have so agreed to purchase, or in such other proportions as the Representatives may specify; provided, however, that in no event shall the maximum number of Firm Shares that any Underwriter has become obligated to purchase pursuant to Section 1 be increased pursuant to this Section 8 by more than one-ninth of such number of Firm Shares without the prior written consent of such Underwriter. If any Underwriter or Underwriters shall fail or refuse to purchase any Firm Shares and the aggregate number of Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase exceeds one-tenth of the aggregate number of the Firm Shares and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any nondefaulting Underwriter or the Company for the purchase or sale of any Shares under this Agreement. In any such case either the Representatives or the Company shall have the right to postpone the Closing but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Any action taken pursuant to this Section 8 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 9. Miscellaneous. Notice given pursuant to any of the provisions of this Agreement shall be in writing and, unless otherwise specified, shall be mailed or delivered (a) if to the Company, at the office of the Company, 900 S.W. Washington Street, Suite 1100, Vancouver, Washington 98660, Attention: Chief Financial Officer, with a copy to Stuart Chestler, Stoel Rives LLP, 900 S.W. Fifth Avenue, Suite 2300, Portland, Oregon 97204 or (b) if to the Underwriters, to the Representatives at the offices of Black & Company, Inc., One S.W.

Fifth Avenue, Suite 1600, Portland, Oregon 97204. Any such notice shall be effective only upon receipt. Any notice may be made by telex, telephone or facsimile, but if so made shall be subsequently confirmed in writing. 25 This Agreement has been and is made solely for the benefit of the several Underwriters, the Company and of the controlling persons, directors and officers referred to in Section 6, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" as used in this Agreement shall not include a purchaser, as such purchaser, of Shares from any of the several Underwriters. This Agreement shall be governed by and construed in accordance with the laws of the State of Oregon applicable to contracts made and to be performed entirely within such state. This Agreement may be signed in two or more counterparts with the same effect as if the signatures thereto and hereto were upon the same instrument. In case any provision in this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. The Company and the Underwriters each hereby waive any right they may have to a trial by jury in respect of any claim based upon or arising out of this Agreement or the transactions contemplated hereby. 26 Please confirm that the foregoing correctly sets forth the agreement among the Company and the several Underwriters.
