For the purposes of this Note, the following terms have the meanings assigned to them below: "Base Rate Payment Date" means (i) the last day of each October, January, April and July of each year, beginning October 31, 1995, and (ii) any day on which past due interest or principal is owed hereunder and is unpaid. If the terms hereof or of the Credit Agreement provide that payments of interest or principal hereon shall be deferred from one Base Rate Payment Date to another day, such other day shall also be a Base Rate Payment Date. "Fixed Rate Payment Date" means, with respect to any Fixed Rate Portion: (i) the day on which the related Interest Period ends (and, if such Interest Period is three months or longer, the three-month anniversary of the first day of such Interest Period), and (ii) any day on which past due interest or past due principal is owed hereunder with respect to such Fixed Rate Portion and is unpaid. If the terms hereof or of the Credit Agreement provide that payments of interest or principal with respect to such Fixed Rate Portion shall be deferred from one Fixed Rate Payment Date to another day, such other day shall also be a Fixed Rate Payment Date. 17 The principal amount of this Note shall be due and payable in eight (8) quarterly installments, each of which shall be equal to one-eighth (1/8) of the aggregate unpaid principal balance of this Note at the end of the Commitment Period, and shall be due and payable on each Base Rate Payment Date, beginning with the first Base Rate Payment Date to occur after the end of the Commitment Period, and continuing regularly thereafter until the Final Maturity Date, at which time the unpaid principal balance of this Note and all interest accrued hereon shall be due and payable in full. The Base Rate Portion of the Loan (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the Base Rate in effect on such day. On each Base Rate Payment Date Borrower shall pay to the holder hereof all unpaid interest which has accrued on the Base Rate Portion to but not including such Base Rate Payment Date. Each Fixed Rate Portion of the Loan (exclusive of any past due principal or interest) shall bear interest on each day during the related Interest Period at the related Fixed Rate in effect on such day. On each Fixed Rate Payment Date relating to such Fixed Rate Portion Borrower shall pay to the holder hereof all unpaid interest which has accrued on such Fixed Rate Portion to but not including such Fixed Rate Payment Date. All past due principal of and past due interest on the Loan shall bear interest on each day outstanding at the Late Payment Rate in effect on such day, and such interest shall be due and payable daily as it accrues. Notwithstanding the foregoing provisions of this paragraph: (a) this Note shall never bear interest in excess of the Highest Lawful Rate, and (b) if at any time the rate at which interest is payable on this Note is limited by the Highest Lawful Rate (by the foregoing clause (a) or by reference to the Highest Lawful Rate in the definitions of Base Rate, Fixed Rate, and Late Payment Rate), this Note shall bear interest at the Highest Lawful Rate and shall continue to bear interest at the Highest Lawful Rate until such time as the total amount of interest accrued hereon equals (but does not exceed) the total amount of interest which would have accrued hereon had there been no Highest Lawful Rate applicable hereto. Notwithstanding the foregoing paragraph and all other provisions of this Note, in no event shall the interest payable hereon, whether before or after maturity, exceed the maximum amount of interest which, under applicable law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully set out the limitations on how interest accrues hereon. In the event applicable law provides for a ceiling under Texas Revised Civil Statutes Annotated article 5069-1.04, that ceiling shall be the indicated rate ceiling and shall be used in this Note for calculating the Highest Lawful Rate and for all other purposes. The term "applicable law" as used in this Note shall mean the laws of the State of Texas or the laws of the United States, whichever laws allow the greater interest, as such laws now exist or may be changed or amended or come into effect in the future. If this Note is placed in the hands of an attorney for collection after default, or if all or any part of the indebtedness represented hereby is proved, established or collected in any court or in any bankruptcy, receivership, debtor relief, probate or other court proceedings, Borrower and all endorsers, sureties and guarantors of this Note jointly and severally agree to pay reasonable attorneys' fees and collection costs to the holder hereof in addition to the principal and interest payable hereunder. 18 Borrower and all endorsers, sureties and guarantors of this Note hereby severally waive demand, presentment, notice of demand and of dishonor and nonpayment of this Note, protest, notice of protest, notice of intention to accelerate the maturity of this Note, declaration or notice of acceleration of the maturity of this Note, diligence in collecting, the bringing of any suit against any party and any notice of or defense on account of any extensions, renewals, partial payments or changes in any manner of or in this Note or in any of its terms, provisions and covenants, or any releases or substitutions of any security, or any delay, indulgence or other act of any trustee or any holder hereof, whether before or after maturity. THIS NOTE AND THE RIGHTS AND DUTIES OF THE PARTIES HERETO SHALL BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW), EXCEPT TO THE EXTENT THE SAME ARE GOVERNED BY APPLICABLE FEDERAL LAW. HECLA MINING COMPANY By: /s/ John P. Stilwell -------------------------------------------- John P. Stilwell Vice President-Finance and Treasurer 19 EXHIBIT B OPINION OF BORROWER'S COUNSEL October __, 1995 NationsBank of Texas, N.A., as Agent under the Agreement referred to below 901 Main Street Dallas, Texas 75202 Attention: Energy Banking Group Ladies and Gentlemen: This opinion is being delivered to you pursuant to Section 3.1(c)(iii) of the First Amendment to Credit Agreement of even date herewith (the "Amendment"), which amends that certain Credit Agreement dated August 30, 1994 (the "Original Agreement"; the Original Agreement as amended by the Amendment, the "Agreement"), by and among Hecla Mining Company ("Borrower"), Colorado Aggregate Company of New Mexico, Inc., a Delaware corporation, Kentucky-Tennessee Clay Company, a Delaware corporation and K-T Feldspar Corporation, a Delaware corporation (each individually, a "Subsidiary Guarantor" and collectively, "Subsidiary Guarantors"), NationsBank of Texas, N.A., as Agent, and the Lenders named therein. The Agreement provides for credit in the maximum principal amount of $55,000,000 to be made available by Lenders to Borrower, in accordance with the terms and provisions therein contained. Terms which are defined in the Agreement and which are used but not defined herein shall have the meanings given them in the Agreement. We have acted as counsel for Borrower and each Subsidiary Guarantor in connection with the transactions provided for in the Agreement. As such counsel we have assisted in the negotiation of the Amendment and the other Loan Documents and have advised our clients of their duties and obligations thereunder. We have examined executed counterparts (or, where indicated, photostatic copies of executed counterparts) of the documents listed in Schedule 1. We have discussed the matters addressed in this opinion with officers and representatives of Borrower and each Subsidiary Guarantor to the extent we have deemed appropriate to enable us to render this opinion. In particular, but without limitation, we have confirmed that Borrower and each Subsidiary Guarantor acknowledges, understands and agrees that the Loan Documents as written set forth the entire understanding and agreement of the parties thereto. In preparing this opinion we have also examined original counterparts or photostatic or certified copies of all other instruments, agreements, certificates, records and other documents (whether of Borrower or any Subsidiary Guarantor, their officers, directors, shareholders and representatives, public officials, or other persons) which we have considered relevant hereto. In making this examination we have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as photostatic or certified copies, and the authenticity of the originals of such copies. 20 Based upon the foregoing, and subject to the qualifications and exceptions hereinafter set forth, we are of the opinion that: 1. Each of Borrower and the Subsidiary Guarantors is duly incorporated, validly existing and in good standing under the laws of the State of Delaware. Each of Borrower and the Subsidiary Guarantors has all requisite corporate power to enter into the Loan Documents and to perform its obligations thereunder. 2. Each of Borrower and the Subsidiary Guarantors is duly qualified to transact business and in good standing in all jurisdictions where the character of its properties or the nature of its activities makes such qualification necessary. 3. All of the outstanding capital stock of each Subsidiary Guarantor is owned of record and, to the best of our knowledge, beneficially by Borrower. All of such outstanding capital stock has been duly authorized and validly issued and is fully paid and non-assessable. To the best of our knowledge, no Subsidiary Guarantor has any obligation or commitment to issue any other shares of capital stock, nor has any Subsidiary Guarantor granted any options with respect thereto. 4. The Amendment, the Replacement Notes made payable to Lenders, the Pledge Agreement (as used herein the terms Replacement Notes and Pledge Agreement shall have the meanings assigned to them in the Amendment) and the Credit Agreement (herein collectively referred to as the "Loan Documents") have been duly authorized, executed and delivered by Borrower and each Subsidiary Guarantor. The Loan Documents constitute legal valid and binding instruments and agreements of Borrower and the Subsidiary Guarantors, and the obligations of Borrower and the Subsidiary Guarantors thereunder are enforceable in accordance with the terms thereof. 5. The execution, delivery and performance by Borrower and each Subsidiary Guarantor of the Loan Documents and the consummation of the transactions contemplated thereby, will not and did not (a) violate or contravene any provision of the charter or bylaws of Borrower or any Subsidiary Guarantor, or, (b) to the best of our knowledge, conflict with or result in a breach of any material term or provision of or constitute a default under or result in the maturing of any indebtedness pursuant to any indenture, mortgage, deed of trust, note or loan agreement, or other material agreement or instrument, of which we have knowledge to which Borrower or any Subsidiary Guarantor is a party or by which any of them or any of their various properties are bound, or, (c) result in a violation of any law, rule or regulation or, to the best of our knowledge, any judgment, order, decree, determination or award of any court or governmental authority which is now in effect and applicable to Borrower or any Subsidiary Guarantor or to any of their properties. To the best of our knowledge, neither Borrower nor any Subsidiary Guarantor is in default under or in violation of any law, rule, regulation, judgment, order, decree, determination, award, indenture, mortgage, deed of trust, note, loan agreement or other material agreement or instrument of which we have knowledge or in violation of its charter or bylaws. 21 6. To the best of our knowledge, no consent, approval, authorization or order of any court or governmental agency or of any third party is or was required (a) for the execution and delivery by Borrower or any Subsidiary Guarantor of the Loan Documents, (b) for the consummation of the transactions contemplated thereby, or (c) for the performance by Borrower or any Subsidiary Guarantor of their various obligations thereunder. 7. To the best of our knowledge there are no actions, suits, proceedings or investigations pending or threatened against or affecting Borrower or any Subsidiary Guarantor or any of their various properties in any court or governmental agency (a) seeking to enjoin, or questioning the legality or validity of, the performance by Borrower or any Subsidiary Guarantor of any of their various obligations under the Loan Documents, or (b) which have, or would have if adversely determined, a material adverse effect on the ability of Borrower or any Subsidiary Guarantor to perform such obligations. 8. To the best of our knowledge, (a) the representations and warranties of Borrower and each Subsidiary Guarantor in the Loan Documents are and were true and correct in all material respects on the date hereof and on the dates when made, and (b) there does not exist on the date hereof any Default or Event of Default under the Credit Agreement. 9. In the course of our representation of Borrower and each Subsidiary Guarantors in connection with the negotiation of the Agreement, we discussed with officers and representatives of Borrower and each Subsidiary Guarantor, to the extent we deemed appropriate, the terms and provisions of the Agreement. Nothing came to our attention in the course of such representation or discussions which has led us to believe that the representations and warranties of Borrower and each Subsidiary Guarantor in the Amendment or the Agreement are not or were not true and correct in all material respects on the date hereof and on the dates when made or that there exists on the date hereof any Default or Event of Default under the Agreement. This opinion is limited by, subject to and based on the following: (a) This opinion is limited in all respects to the General Corporation Law of the State of Delaware, the laws of the State of Colorado and applicable federal law; however, we are not members of the bar of the State of Delaware and our knowledge of its General Corporation Law is derived from a reading of that statute without consideration of any judicial or administrative interpretations thereof. (b) In rendering the opinion expressed in the second sentence of paragraph 4 hereof, we have assumed that the Loan Documents have been duly authorized, executed and delivered by Agent and each Lender (to the extent that each is a party thereto). (c) In connection with opinions expressed herein as being limited "to the best of our knowledge", our examination has been limited to discussions with the officers and representatives of Borrower and each Subsidiary Guarantor in the course of this transaction, and our knowledge of the affairs of Borrower and each Subsidiary Guarantor as their counsel, and we have made no independent investigations as to the accuracy or completeness of any representations, warranties, data or other information, written or oral, made or furnished by any of them to us, to Agent or to any Lender. 22 (d) We have made no examination of and express no opinion with respect to (i) titles to or, except as to adequacy of form, descriptions of the properties described in the Loan Documents, (ii) whether there are of record any liens, security interests, charges or encumbrances thereon, or (iii) the filing or recording of the Loan Documents or any financing statements or other instruments relating thereto. (e) The enforceability of the respective obligations of the parties to the Loan Documents, and the availability of certain rights and remedies provided for therein, may be limited by (i) applicable state and federal laws and judicial decisions, but the remedies provided for in the Loan Documents are adequate for the practical realization of the benefits provided thereby, (ii) equitable principles which may limit the availability of certain equitable remedies (such as specific performance) in certain instances, or (iii) applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally. The opinions herein expressed are for the benefit of Agent and Lenders and may be relied upon only by Agent, Lenders and by Thompson & Knight, A Professional Corporation, in connection with any opinion delivered by them to Agent.
