4. Valid Issuance. The Collateral consists of validly issued, fully paid and nonassessable shares.

9. Company Consent. The Pledgor has obtained any and all required consents of the Company for the transactions contemplated by this Agreement, including without limitation the pledge of the Collateral.
10. Margin Regulations. The Collateral is not "margin stock" within the meaning of the Regulation U promulgated by the Board of Governors of the Federal Reserve System, and no part of the proceeds of the loans evidenced by the Notes will be used, whether directly or indirectly, or whether immediately, incidentally or ultimately, (a) to purchase or carry any "margin stock" or to extend credit to others for the purpose of purchasing or carrying any "margin stock" or to refund indebtedness incurred for such purpose or (b) for any purpose which entails a violation of, or is inconsistent with, the provisions of Regulations U or X promulgated by such Board of Governors.

5. Exercise of Shareholder Rights.

(a) Receipt of Dividends and Distributions. Prior to the occurrence of a Default, the Pledgor shall have the right to receive and retain any ordinary dividends or other distributions paid on the Collateral.

(b) Right to Vote. Prior to the occurrence of a Default, the Pledgor may vote the Collateral for all purposes allowed within the restrictions set by this Agreement. The Pledgor agrees not to vote the Collateral or otherwise to act in any way which will adversely affect the value of the Collateral.

1. Remedies Upon Default.

(a) Pledgee May Register Shares. Upon the occurrence of a Default, the Pledgee may cause the Collateral to be transferred to the Pledgee's name and may exercise any right normally incident to the ownership of the Collateral, including the right to vote and to receive all dividends or other payments.

(b) Collateral. Upon the occurrence of a Default, the Pledgee may sell all or any part of the Collateral at public or private sale. The Pledgee may purchase all or any part of the Collateral at the sale. Proceeds of any sale shall be applied first to pay all costs and expenses related to the Default and sale of the Collateral, including all attorneys' fees, and second, to pay all amounts owed on the Obligations, with any excess to be returned to the Pledgor.

(c) Remedies Cumulative. Upon the occurrence of a Default, the Pledgee shall have all rights and remedies available to them at law or in equity, including all rights available under the Uniform Commercial Code, and all rights and remedies granted under this Agreement, the Note, the Security Agreement and any other related documents or agreements. These rights and remedies shall be cumulative, and may be exercised singly or concurrently with all other rights and remedies the Pledgee may have.

(d) Order of Realization on the Collateral. The Pledgee may realize upon the Collateral, as well as any other collateral, in any order.

(e) Acknowledgments and Agreements of Pledgor. The Pledgor hereby acknowledges and agrees (i) that the Pledgor hereby waives all rights of redemption, stay, valuation and appraisal under any applicable laws, (ii) that ten (10) days prior written notice of the Pledgee's intention to make any sale of the Collateral is commercially reasonable notice, (iii) that the requirements of federal and state securities laws may limit the Pledgee's sale of all or part of the Collateral as well as the extent or manner in which any subsequent transferee could dispose of the same, (iv) in light of such restrictions, the Pledgee may effect a private sale to one or more purchasers who will agree, among other things, to acquire the Collateral for their own account, for investment, and not with a view to the distribution or resale thereof, (v) that the Pledgee may proceed to make such a sale whether or not a registration statement for the purpose of registering the Collateral shall have been filed and may approach and negotiate with a single potential purchaser to effectuate such sale, (vi) any such sale might result in prices or other terms less favorable than if such sale were a public sale without such restrictions, and the Pledgee shall incur no liability for selling any Collateral under such circumstances, and (vii) the foregoing shall apply not withstanding the existence of a public or private market upon which the quotations or sales prices may exceed substantially the price at which the Pledgee sells.

(f) Registration. The Pledgor hereby assigns to the Pledgee, upon the occurrence of a Default, all registration rights the Pledgor now has or may hereafter acquire with respect to the Collateral. If the Pledgees desires to sell any of the Collateral at a public sale, the Pledgor will, upon request of the Pledgee, use its best efforts to cause the issuer of the Collateral to register the Collateral under federal and state securities laws and maintain the effectiveness of such registration, to the extent consistent with such registration rights. The Pledgor further agrees to indemnify, defend and hold harmless the Pledgee, any underwriter and their respective officers, directors, affiliates and controlling persons from and against all loss, liability, expenses, costs of counsel and claims (including the costs of investigation) that they may incur in so far as such loss, liability, expense or claim arising out of or is based upon any alleged untrue statement of a material fact contained in any prospectus, or arises out of or is based upon any alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except in so far as they may have been caused by any untrue statement or omission based upon the information furnished in writing by the Pledgee expressly for use therein. The Pledgee will bear all costs and expenses of carrying out the foregoing obligations on its part. The Pledgor acknowledges and agrees that there is no adequate remedy at law for failure by it to comply with the provisions of this Section and that such failure would not be adequately compensable in damages, and therefore agrees that its agreements contained in this Section may be specifically enforced.

(g) Rights of Other Creditors. The security interest of the Pledgee and the rights of the Pledgee upon the occurrence of any Default or otherwise under this Agreement shall be subject to (i) the senior first-priority security interest of the Koyah Collateral Agent and the senior second-priority security interests of Raven and Ventures and (ii) the rights of the Koyah Collateral Agent, Raven and Ventures upon the occurrence of any default or otherwise under their security documents.
