Each share of common stock of the Company, par value $.001 per share ("Company Stock"), issued and outstanding immediately prior to the Effective Time (other than any shares of Company Stock to be canceled pursuant to Section 3.1.2), shall be converted into the right to receive 0.2218 (the "Exchange Ratio") shares of Parent Common Stock (the "Merger Consideration"). All shares of Company Stock that have been converted into the right to receive the Merger Consideration as provided in this Section 3.1.1 shall as of the Effective Time no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each Certificate and each Book-Entry Share which immediately prior to the Effective Time represented such shares shall thereafter represent only the right to receive the Merger Consideration therefor in accordance with the terms of this Agreement. Certificates and Book-Entry Shares previously representing shares of Company Stock (other than any shares of Company Stock to be canceled pursuant to Section 3.1.2) shall be exchanged for the Merger Consideration, without interest, upon the surrender of such Certificates or Book-Entry Shares in accordance with the provisions of Section 3.3.

Section 3.2 Treatment of Stock Options, Warrants, and Preferred Stock.

Section 3.2.1 Stock Options. At the Effective Time, each option (each, a "Company Stock Option") to purchase shares of Company Stock granted under the Company Stock Plans that is outstanding immediately prior to the Effective Time (whether or not vested) shall be deemed fully vested and shall be cancelled in exchange for the right to receive shares of Parent Common Stock (without interest, and subject to deduction for any required withholding Tax, with cash being paid in lieu of issuing fractional shares of Parent Common Stock) with a value equal to the product of (i) the excess (if any) of the Merger Consideration Closing Value minus the exercise price per share under such Company Stock Option and (ii) the number of shares subject to such Company Stock Option; provided, however, that (a) if the exercise price per share of any such Company

Stock Option is equal to or greater than the Merger Consideration Closing Value, such Company Stock Option shall be cancelled without any payment being made in respect thereof, and (b) at the option of Parent, in lieu of paying all or a portion of the amounts due to a holder of Company Stock Options under this paragraph in shares of Parent Common Stock, Parent may substitute for such shares an equivalent amount in cash, and (c) such holders of Company Stock Options shall have delivered to the Company an executed Option Consent Agreement. For purposes of the preceding sentence, the shares of Parent Common Stock to be issued to holders of Company Stock Options shall be deemed to have a value equal to the closing price of Parent Common Stock on the NYSE on the trading day immediately preceding the Closing Date. Promptly following the Closing Date (and, in any event, within ten Business Days thereof), Parent shall (1) if any shares of Parent Common Stock are being issued to any holder of Company Stock Options, cause Parent's transfer agent to issue such Parent Common Stock, and (2) if any cash payments are being made to any holder of Company Stock Options, cause the Company to process such payments through its payroll system.

Section 3.2.2 Warrants. At the Effective Time, and in accordance with the terms of each warrant to purchase shares of Company Stock that is listed on Section 4.2.3 of the Company Disclosure Schedule (collectively, the "Warrants") and that is issued and outstanding immediately prior to the Effective Time, a replacement warrant shall be issued to each holder of a Warrant providing that such replacement warrant shall be exercisable for a number of shares of Parent Common Stock (without interest, and subject to deduction for any required withholding Tax, and no issuance of fractional shares and the number of such shares rounded down) equal to the product of (i) the Exchange Ratio and (ii) the number of shares subject to such Warrant, with an exercise price of $4.8765. From and after the Closing, Parent shall comply with all of the terms and conditions set forth in each such replacement warrant.

Section 3.2.3 Company Preferred Stock. At the Effective Time, and in accordance with the terms of the Company Preferred Stock, replacement preferred stock shall be issued to each holder of Company Preferred Stock that is listed on Section 4.2.3 of the Company Disclosure Schedule and that is issued and outstanding immediately prior to the Effective Time, providing that such replacement preferred stock shall have a conversion price of $3.5464 and contain such other terms as are required by the terms of the Company Preferred Stock.

As of the Effective Time, all Company Stock Plans shall be terminated and no further awards or other rights shall be granted thereunder.

Section 3.3 Exchange of Certificates.

Section 3.3.1 Exchange Agent. Prior to the Closing Date, Parent shall appoint an exchange agent reasonably acceptable to the Company (the "Exchange Agent") for the purpose of exchanging shares of Company Stock for Merger Consideration. Prior to the Effective Time, Parent shall make available to the Exchange Agent, for the benefit of the holders of shares of Company Stock, shares of Parent Common Stock and, if applicable, cash in an amount equal to the aggregate Merger

Consideration to be paid pursuant to this Article 3 (the certificates representing the shares of Parent Common Stock comprising such aggregate Merger Consideration and, if applicable, cash in lieu of fractional shares, being referred to hereinafter as the "Stock Merger Exchange Fund"). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration out of the Stock Merger Exchange Fund. The Stock Merger Exchange Fund shall not be used for any purpose other than as set forth in this Agreement.

Section 3.3.2 Exchange Procedures. Promptly following the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Stock (the "Certificates") or of non-certificated shares of Company Stock represented by book-entry ("Book-Entry Shares") (a) a letter of transmittal in customary form, which shall be subject to the reasonable approval of the Parties prior to the Effective Time, and (b) instructions for use in effecting the surrender of Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares in exchange for the Merger Consideration. Upon surrender of Certificates (or affidavits of loss and, if reasonably requested by Parent, appropriate bonds in lieu thereof), or in the case of Book-Entry Shares, upon adherence to the applicable procedures set forth in the letter of transmittal, for cancellation to the Exchange Agent together with such letter of transmittal, properly completed and duly executed in accordance with the instructions thereto, and such other documents as may be reasonably required by the Exchange Agent or pursuant to such instructions, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration, without interest, allocable to such Certificates or Book-Entry Shares, and the Certificates or Book-Entry Shares so surrendered shall forthwith be canceled. In the event of a transfer of ownership of shares of Company Stock which is not registered in the transfer records of the Company, the Merger Consideration may be issued to a transferee if the Certificate representing such shares of Company Stock is presented to the Exchange Agent (or in the case of Book-Entry Shares, upon adherence to the applicable procedures set forth in the letter of transmittal), accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 3.3, each Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration allocable to such Certificates or Book-Entry Shares. No dividends or other distributions with respect to Parent Common Stock issued in the Merger having a record date after the Effective Time and payable to the holders of record thereof after the Effective Time will be paid to Persons entitled by reason of the Merger to receive Parent Common Stock until such Persons surrender their Certificates (or in the case of Book-Entry Shares, upon adherence to the applicable procedures set forth in the letter of transmittal) as provided in this Section 3.3.2. Upon such surrender, there shall be paid to the Person in whose name the Merger Consideration is issued any dividends or other distributions having a record date after the Effective Time and payable with respect to such Parent Common Stock between the Effective Time and the time of such surrender. After such surrender, at the appropriate payment date, there shall be paid to the Person in whose name the Merger Consideration is issued any dividends or other distributions on such Parent Common Stock with a payment date after such surrender which shall have a record date after the Effective Time. In no event shall the Persons entitled to receive such dividends or other distributions be entitled to receive interest on such dividends or other distributions.

Section 3.3.3 Further Rights in Company Stock. All Merger Consideration paid in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Stock.

Section 3.3.4 Termination of Stock Exchange Fund. Any portion of the Stock Merger Exchange Fund (including any interest received with respect thereto) which remains undistributed

to the holders of Company Stock on the day that is six months after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Stock who have not theretofore complied with this Article 3 shall thereafter look only to Parent (subject to abandoned property, escheat or other similar Laws) for payment of the Merger Consideration, without any interest thereon.

Section 3.3.5 No Liability. Neither the Exchange Agent nor any of the Parties shall be liable to any holder of shares of Company Stock entitled to payment of the Merger Consideration under this Article 3 for any Merger Consideration (including any interest or cash in lieu of fractional shares) from the Stock Merger Exchange Fund properly delivered to a public official pursuant to any abandoned property, escheat or similar Law. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the Parent Common Stock held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such Parent Common Stock for the account of the Persons entitled thereto.

Section 3.3.6 Lost Certificates. If 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 in the form required by the Exchange Agent and, if reasonably required by Parent, the posting by such Person of a bond, in such reasonable and customary amount as Parent may direct, as indemnity against any claim that may be made with respect to such lost, stolen or destroyed Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration without any interest thereon.

Section 3.3.7 Withholding. Each of Parent, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Stock such amounts as Parent, the Surviving Corporation, or the Exchange Agent are required to deduct and withhold under the Code, or any applicable provision of state, local or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent, the Surviving Corporation, or the Exchange Agent and paid over to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Stock in respect of whom such deduction and withholding was made by Parent, the Surviving Corporation or the Exchange Agent, as the case may be.

Section 3.4 Fractional Shares. If a holder of shares of Company Stock is entitled to receive any fractional share of Parent Common Stock based on application of the Exchange Ratio to the total number of shares of Company Stock held by such holder immediately prior to the Effective Time, such holder will be entitled to receive, at Parent's option, either (i) such fractional share or (ii) cash in lieu of such fractional shares based on the Merger Consideration Closing Value.

Section 3.5 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Stock outstanding on the records of the Company prior to the Effective Time. From and after the Effective Time, the holders of Certificates and Book-Entry Shares shall cease to have any rights with respect to the shares of Company Stock represented thereby except as otherwise provided herein or by Law. From and after the Effective Time, any Certificates presented to the Exchange Agent, Parent or the Surviving Corporation for transfer or any other reason shall be cancelled and exchanged for the applicable Merger Consideration as provided in, and in accordance with, this Article 3.

Section 6.4.2 Notwithstanding Section 6.4.1, prior to the receipt of the Shareholder Approval, the Company Board, directly or indirectly through any Company Representative, may, subject to Section 6.4.3, and provided that the Company is not then in breach of Section 6.4.1 (i) participate in negotiations or discussions with any third party that has made (and not withdrawn) a bona fide, unsolicited Takeover Proposal in writing that the Company Board believes in good faith, after consultation with outside legal counsel and an independent financial advisor, constitutes or would reasonably be expected to result in a Superior Proposal, (ii) furnish to the third party that has made such Takeover Proposal non-public information relating to the Company or any of its Subsidiaries pursuant to an executed confidentiality agreement that contains confidentiality provisions that are no less favorable to the Company than those contained in the Confidentiality Agreement (a copy of which confidentiality agreement shall be promptly (in all events within 24 hours) provided for informational purposes only to Parent), except that such agreement need not contain any standstill or similar provision, (iii) following receipt of and on account of a Superior Proposal, make a Company Adverse Recommendation Change in accordance with the provisions of Section 6.4.4, or (iv) take any action that any court of competent jurisdiction orders the Company to take (which Order remains unstayed), but in each case referred to in the foregoing clauses (i) through (iv), only if the Company Board determines in good faith, after consultation with outside legal counsel, that the failure to take such action would reasonably be expected to cause the Company Board to be in breach of its fiduciary duties under applicable Law. The Company Board shall be permitted to disclose to the Company's shareholders a position, otherwise in compliance with the terms and conditions of this Agreement, contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act with regard to a Takeover Proposal, if the Company determines, after consultation with outside legal counsel, that failure to disclose such position would constitute a violation of applicable Law. Nothing in this Agreement shall prohibit the Company Board from complying with its disclosure obligations under U.S. federal or state Law.

Section 6.4.3 The Company Board shall not take any of the actions referred to in clauses (i) through (iv) of Section 6.4.2 unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action. The Company shall notify Parent promptly (but in no event later than 24 hours) after it obtains Knowledge of the receipt by the Company (or any of the Company Representatives) of any Takeover Proposal, any inquiry that would reasonably be expected to lead to a Takeover Proposal, or any request for non-public information relating to the Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries by any third party. In such notice, the Company shall identify the third party making, and details of the material terms and conditions of, any such Takeover Proposal, indication or request. The Company shall keep Parent fully informed, on a current basis, of the status and material terms of any such Takeover Proposal, indication or request, including any material amendments or proposed amendments as to price and other material terms thereof. The Company shall provide Parent with at least 48 hours prior notice of any meeting of the Company Board (or such lesser notice as is provided to the members of the Company Board) at which the Company Board is reasonably expected to consider any Takeover Proposal. The Company shall promptly (but in no event later than 24 hours) provide Parent with a list of any non-public information concerning the Company's business, present or future performance, financial condition or results of operations provided to any third party in connection with the receipt by the Company (or any of the Company Representatives) of any such Takeover Proposal, indication or request and copies of such information to the extent not previously provided to Parent.

Section 6.4.4 Except as set forth in this Section 6.4.4, the Company Board shall not make any Company Adverse Recommendation Change or enter into (or permit any Subsidiary to enter into) a Company Acquisition Agreement. At any time prior to the receipt of the Shareholder Approval,

in response to a Superior Proposal, the Company Board may make a Company Adverse Recommendation Change, take an action otherwise prohibited under Section 6.4.1(ii) or, subject to compliance with Section 8.1(iii)(b), enter into (or permit any Subsidiary to enter into) a Company Acquisition Agreement, if: (i) the Company promptly notifies Parent, in writing, at least three Business Days (the "Notice Period") before making a Company Adverse Recommendation Change, taking an action otherwise prohibited under Section 6.4.1(ii) or entering into (or causing a Subsidiary to enter into) a Company Acquisition Agreement, of its intention to take such action with respect to a Superior Proposal, which notice shall state expressly that the Company has received a Takeover Proposal that the Company Board intends to declare a Superior Proposal and that the Company Board intends to make a Company Adverse Recommendation Change, or take an action otherwise prohibited under Section 6.4.1(ii) or the Company intends to enter into a Company Acquisition Agreement; (ii) the Company attaches to such notice the most current version of the proposed Company Acquisition Agreement (which version shall be updated on a prompt basis) and identifies the third party making such Superior Proposal; (iii) the Company shall, and shall cause its Subsidiaries to, and shall use its reasonable best efforts to cause the Company Representatives to, during the Notice Period, negotiate with Parent in good faith to make such adjustments in the terms and conditions of this Agreement so that such Takeover Proposal ceases to constitute a Superior Proposal, if Parent, in its discretion, proposes to make such adjustments (it being agreed that, in the event that after commencement of the Notice Period, there is any material revision to the terms of a Superior Proposal, including any revision in price, the Notice Period shall, if less than two Business Days remain before the expiration of such Notice Period, be automatically extended to two Business Days from the date on which the Company notifies Parent of any such material revision (it being understood that there may be multiple extensions)); and (iv) the Company Board determines in good faith, after consulting with outside legal counsel and an independent financial advisor, that such Takeover Proposal continues to constitute a Superior Proposal after taking into account any adjustments made by Parent during the Notice Period in the terms and conditions of this Agreement and that the failure to accept such Superior Proposal would reasonably be expected to cause the Company Board to be in breach of its fiduciary duties under applicable Law.

Section 6.5 Reasonable Best Efforts.

Section 6.5.1 General. Upon the terms and subject to the conditions set forth in this Agreement (including those contained in this Section 6.5.1), each of the Parties shall, and shall cause its Subsidiaries to, use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary, proper or advisable to consummate and make effective, and to satisfy all conditions to, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including (i) the obtaining of all necessary permits, waivers, consents, approvals and actions or nonactions from Governmental Entities and the making of all necessary registrations and filings (including filings with Governmental Entities) and the taking of all steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entities, (ii) the obtaining of all necessary consents or waivers from third parties, and (iii) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of this Agreement.

by this Agreement, then it shall use reasonable best efforts to make, or cause to be made, as soon as reasonably practicable and after consultation with the other Party, an appropriate response in compliance with such request, and, if permitted by applicable Law and by any applicable Governmental Entity, provide the other Party's counsel with advance notice and the opportunity to attend and participate in any meeting with any Governmental Entity in respect of any filing made therewith in connection with the transactions contemplated by this Agreement.

Notwithstanding anything in this Agreement to the contrary, none of Parent, Merger Sub or any of their Affiliates shall be required to defend, contest or resist any action or proceeding, whether judicial or administrative, or to take any action to have vacated, lifted, reversed or overturned any Order, in connection with the transactions contemplated by this Agreement.

Section 6.5.4 Exceptions.

which relate to this Agreement, the Merger or the other transactions contemplated hereby and (c) any fact, event or circumstance known to such Party that would cause or constitute, or would reasonably be expected to cause or constitute, a breach in any material respect of such Party's representations, warranties, covenants or agreements contained herein or would prevent, delay or impede, or would reasonably be expected to prevent, delay or impede, the consummation of the Merger or any other transaction contemplated by this Agreement; provided, however, that the delivery of any notice pursuant to this Section 6.6 shall not limit or otherwise affect any remedies available to the Party receiving such notice or prevent or cure any misrepresentations, breach of warranty or breach of covenant or failure to satisfy the conditions to the obligations of the Parties under this Agreement.

Section 6.7 Public Announcements. Except as set forth in this Section 6.7, the Parties agree that Parent will prepare and disseminate any press release or public announcement pertaining to the Merger, and shall in good faith consult with the Company as to the text of any such press release or public announcement, provided that all decisions with respect to such press releases and public announcements shall ultimately rest with Parent. The Company shall not issue any press release or public statement pertaining to the Merger without consulting with, and obtaining the consent of, Parent, which consent shall not be unreasonably withheld or delayed, except as required to comply with any Law.

(i) In current market conditions, the Company will have difficulty developing the Montanore Project. The Company owes it to its shareholders and all stakeholders to be responsible in light of current realities.

Section 6.9.1 Parent and Merger Sub agree that all rights to indemnification, advancement of expenses and exculpation by the Company now existing in favor of each Person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time an officer or director of the Company and its Subsidiaries (each an "Indemnified Party") as provided in the Company's Charter Documents, in each case as in effect on the date of this Agreement, or pursuant to any other Contracts in effect on the date hereof and disclosed on Section 6.9.1 of the Company Disclosure Schedule, shall be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time and shall survive the Merger and shall remain in full force and effect in accordance with their terms, and, in the event that any proceeding is pending or asserted or any claim made during such period, until the final disposition of such proceeding or claim.

Section 6.9.2 For six years after the Effective Time, to the fullest extent permitted under applicable Law, Parent and the Surviving Corporation shall indemnify, defend and hold harmless each Indemnified Party against all losses, claims, damages, Liabilities, fees, expenses, judgments and fines arising in connection with any claim brought by a third party arising in whole or in part out of actions or omissions in such Indemnified Party's capacity as such occurring at or prior to the

Effective Time (including in connection with the transactions contemplated by this Agreement), and shall reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such losses, claims, damages, Liabilities, fees, expenses, judgments and fines as such expenses are incurred, subject to the Surviving Corporation's receipt of an undertaking by such Indemnified Party to repay such legal and other fees and expenses paid in advance if it is ultimately determined in a final and non-appealable judgment of a court of competent jurisdiction that such Indemnified Party is not entitled to be indemnified under applicable Law; provided, however, that the Surviving Corporation shall not be liable for any settlement effected without the Surviving Corporation's prior written consent.

Section 6.9.3 The Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, (i) maintain in effect for a period of six years after the Effective Time, if available, the current policies of directors' and officers' liability insurance maintained by the Company immediately prior to the Effective Time (provided that the Surviving Corporation may substitute therefor policies, of at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the directors and officers of the Company and its Subsidiaries when compared to the insurance maintained by the Company as of the date hereof), or (ii) obtain as of the Effective Time "tail" insurance policies with a claims period of six years from the Effective Time with at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the directors and officers of the Company and its Subsidiaries, in each case with respect to claims arising out of or relating to events which occurred before or at the Effective Time (including in connection with the transactions contemplated by this Agreement); provided, however, that in no event will the Surviving Corporation be required to expend an annual premium for such coverage in excess of 200% of the last annual premium paid by the Company for such insurance prior to the date of this Agreement (the "Maximum Premium"). The Maximum Premium is set forth on Section 6.9.3 of the Company Disclosure Schedule. If such insurance coverage cannot be obtained at an annual premium equal to or less than the Maximum Premium, the Surviving Corporation will obtain, and Parent will cause the Surviving Corporation to obtain, that amount of directors' and officers' insurance (or "tail" coverage) obtainable for an annual premium equal to the Maximum Premium.

Section 6.9.4 The obligations of Parent and the Surviving Corporation under this Section 6.9 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 6.9 applies without the consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 6.9 applies shall be third party beneficiaries of this Section 6.9, each of whom may enforce the provisions of this Section 6.9).

The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors' and officers' insurance claims under any policy that is or has been in existence with respect to the Company or its officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 6.9 is not prior to, or in substitution for, any such claims under any such policies.

If any state takeover statute or similar statute becomes applicable to this Agreement (including the Merger and the other transactions contemplated hereby), each of Parent, Merger Sub, the Company and their respective boards of directors shall take all reasonable action necessary so that such transactions may be consummated as promptly as practicable on the terms contemplated hereby or otherwise act to eliminate or minimize the effect of such statute or regulation on this Agreement or the transactions contemplated hereby.

Section 6.11 Section 16(b) Exemption.

Upon a determination that any term or other provision of this Agreement is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the greatest extent possible.
