ARTICLE V

REGISTRATION RIGHTS

5.1 Registration Rights. The Seller agrees that it will prepare and file with the Securities and Exchange Commission (the “Commission”), within 90 days of the joint written demand of the Purchaser, Andora Investments Limited Partnership and Nahara Group, Inc., a registration statement under the Securities Act (the “Registration Statement”), at the sole expense of the Seller (except as otherwise provided herein), in respect of Purchaser, Andora Investments Limited Partnership and Nahara Group, so as to permit a public offering and resale of the Purchased Stock under the Securities Act by Purchaser. The Seller will notify Purchaser of the effectiveness of the Registration Statement within one trading day of such event.

The Seller will maintain the Registration Statement or post-effective amendment filed hereunder effective under the Securities Act until the earliest of: (i) the date that none of the Purchased Stock are or may become issued and outstanding; (ii) the date that all of the Purchased Stock have been sold pursuant to the Registration Statement; (iii) the date the purchasers thereof receive an opinion of counsel to the Seller, that the Purchased Stock may be sold under the provisions of Rule 144 without limitation as to volume; (iv) all Purchased Stock has been otherwise transferred to persons who may trade such shares without restriction under the Securities Act, and the Seller has delivered a new certificate or other evidence of ownership for such securities not bearing a restrictive legend; or (v) all Purchased Stock may be sold without any time, volume or manner limitations pursuant to Rule 144(k) or any similar provision then in effect under the Securities Act in the opinion of counsel to the Seller reasonably acceptable to the Purchaser (the “Effectiveness Period”).

All fees, disbursements and out-of-pocket expenses and costs incurred by the Seller in connection with the preparation and filing of the Registration Statement and in complying with applicable securities and blue sky laws (including, without limitation, all attorneys’ fees of the Seller) shall be borne by the Seller. The Purchaser shall bear the cost of

6

underwriting and/or brokerage discounts, fees and commissions, if any, applicable to the Purchased Stock being registered and the fees and expenses of its counsel.

The Seller shall not be required by this Section to include the Purchased Stock in any Registration Statement which is to be filed if, in the opinion of counsel for the Seller the proposed offering or other transfer as to which such registration is requested is exempt from applicable federal and state securities laws and would result in all Purchasers or transferees obtaining securities which are not “restricted securities,” as defined in Rule 144.

If at any time or from time to time after the effective date of the Registration Statement, the Seller notifies the Purchaser in writing of the existence of a Potential Material Event (as defined below), the Purchaser shall not offer or sell any Purchased Stock or engage in any other transaction involving or relating to Purchased Stock, from the time of the giving of notice with respect to a Potential Material Event until the Purchaser receives written notice from the Seller that such Potential Material Event either has been disclosed to the public or no longer constitutes a Potential Material Event. If a Potential Material Event shall occur prior to the date the Registration Statement is filed, then the Seller’s obligation to file the Registration Statement shall be delayed without penalty for not more than 45 days. The Seller must give Purchaser notice in writing at least two trading days prior to the first day of the blackout period, if lawful to do so.

“Potential Material Event” means any of the following: (a) the possession by the Seller of material information that is not ripe for disclosure in a registration statement, as determined in good faith by the Chief Executive Officer or the Board of Directors of the Seller or that disclosure of such information in the Registration Statement would be detrimental to the business and affairs of the Seller; or (b) any material engagement or activity by the Seller which would, in the good faith determination of the Chief Executive Officer or the Board of Directors of the Seller, be adversely affected by disclosure in a registration statement at such time, which determination shall be accompanied by a good faith determination by the Chief Executive Officer or the Board of Directors of the Seller that the Registration Statement would be materially misleading absent the inclusion of such information.

5.2 Cooperation. Purchaser will cooperate with the Seller in all respects in connection with this Agreement, including timely supplying in writing all information reasonably requested by the Seller (which shall include all information regarding the Purchaser and proposed manner of sale of the Purchased Stock required to be disclosed in the Registration Statement) and executing and returning all documents reasonably requested in connection with the registration and sale of the Purchased Stock and entering into and performing its obligations under any underwriting agreement, if the offering is an underwritten offering, in usual and customary form, with the managing underwriter or underwriters of such underwritten offering. The Purchaser shall consent to be named as an underwriter in the Registration Statement. Purchaser acknowledges that in accordance with current Commission policy, the Purchaser will be named as the underwriter of the Purchased Stock in the Registration Statement.
