Each party hereto, whether maker, co-maker, guarantor or otherwise, waives diligence, demand, presentment for payment, notice of non-payment, protest and notice of protest and waives all defenses based on suretyship or impairment of collateral. Without notice to Borrower and without diminishing or affecting Lender's rights or Borrower's obligations hereunder, Lender may deal in any manner with any person who at any time is liable for, or provides any real or personal property collateral for, any indebtedness of Borrower to Lender, including the indebtedness evidenced by this note. Without limiting the foregoing, Lender may, in its sole discretion: (a) make secured or unsecured loans to Borrower and agree to any number of waivers, modifications, extensions and renewals of any length of such loans, including the loan evidenced by this note; (b) impair, release (with or without substitution of new collateral), fail to perfect a security interest in, fail to preserve the value of, fail to dispose of in accordance with applicable law, any collateral provided by any person; (c) sue, fail to sue, agree not to sue, release, and settle or compromise with, any person. 20. JOINT AND SEVERAL LIABILITY. All undertakings of the undersigned Borrowers are joint and several and are binding upon any marital community of which any of the undersigned are members. Holder's rights and remedies under this note shall be cumulative. 21. SEVERABILITY. If any term or provision of this note is declared by a court of competent jurisdiction to be illegal, invalid or unenforceable for any reason whatsoever, such illegality, invalidity or unenforceability shall not affect the balance of the terms and provisions hereof, which terms and provisions shall remain binding and enforceable, and this note shall be construed as if such illegal, invalid or unenforcable provision had not been contained herein. 22. ARBITRATION. (a) Either Lender or Borrower may require that all disputes, claims, counterclaims and defenses, including those based on or arising from any alleged tort ("Claims") relating in any way to this note or any transaction of which this note is a part ( the "Loan"), be settled by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association and Title 9 of the U.S. Code. All claims will be subject to the statutes of limitation applicable if they were litigated. This provision is void if the Loan, at the time of the proposed submission to arbitration, is secured by real property located outside of Oregon or Washington, or if the effect of the arbitration procedure ( as opposed to any Claims of Borrower) would be to materially impair Lender's ability to realize on any collateral securing the Loan. (b) If arbitration occurs and each party's claim is less than $100,000, one neutral arbitrator will decide all issues; if any party's claim is $100,000 or more,three neutral arbitrators will decide all issues. All arbitrators will be active Oregon State Bar members in good standing. All arbitration hearings will be held in Portland, Oregon. In addition to all other powers, the arbitrator(s) shall have the exclusive right to Summit Design, Inc. 4/9/97 Page 17 determine all issues of arbitrability. Judgment on any arbitration award may be entered in any court with jurisdiction. (c) If either party institutes any judicial proceeding relating to the Loan, such action shall not be a waiver of the right to submit any Claim to arbitration. In addition, each has the right before, during and after any arbitration to exercise any number of the following remedies, in any order or concurrently: (i) Setoff; (ii) self-help repossession; (iii) judicial or non-judicial foreclosure against real or personal property collateral;and (iv) provisional remedies, including injunction, appointment of receiver, attachement, claim and delivery and replevin. 23. GOVERNING LAW. This note shall be governed by and construed and enforced in accordance with the laws of the State of Oregon without regard to conflicts of law principles; PROVIDED, however, that to the extent that Lender has greater rights or remedies under Federal law, this provision shall not be deemed to deprive Lender of such rights and remedies as may be available under Federal law. 24.
