REQUIRED REGISTRATION. The Company shall cause to be included in the "Required Registration Statement" (as defined below) the resale of all of the Common Stock ("Warrant Shares") issuable upon exercise of the warrants ("Warrants") issued to Holders on or about June 2, 1997 in connection with the Offering. For purposes hereof, "Required Registration Statement" shall mean the SEC registration statement filed on Form S-3 (or other appropriate form) pursuant to the Registration Rights Agreement by and among the Company, CC Investments, LDC and the Matthew Fund, N.V., on or about June 2, 1997 in conjunction with the Offering, and thereafter shall not be obligated to effect a Piggyback Registration under Section 2 hereof for as long as the Required Registration Statement is maintained effective. 2. PIGGYBACK REGISTRATION. If (but without any obligation to do so) the Company proposes to register any of its Common Stock under the Act in connection with the public offering of such securities solely for cash (other than (i) a registration relating solely to the sale of securities to participants in a Company stock or other benefit plan, or (ii) a registration of stock options, stock purchase or compensation or incentive plans or securities issued or issuable pursuant to any such plan on Form S-8 or comparable form then in effect), the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given by fax within ten (10) days after mailing of such notice by the Company, which request shall state the intended method of disposition of such shares by such Holder, the Company shall cause to be included in such registration all of the Warrant Shares that each such Holder has requested to be registered (a "Piggyback Registration"). 3. EXPENSES OF REGISTRATION. All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Section 1 or 2, including (without limitation) all registration, filing and qualification fees, printers' and accounting fees, fees and disbursements of counsel for the Company (and including the reasonable fees and disbursements incurred of only one counsel for the selling Holders selected by them) shall be borne by the Company. 4. INDEMNIFICATION. In the event any Warrant Shares are included in a registration statement under this Agreement: 80 3 (a) To the extent permitted by law, the Company will indemnify and hold harmless each "Holder Indemnified Persons" (defined for purposes of this Section 4 as each Holder, the officers and directors of each Holder acting in their capacity as such, any underwriter (as defined in the Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934 Act")), against any losses, claims, damages, expenses, or liabilities (joint or several)("Losses") to which they may become subject under the Act, the 1934 Act or other federal or state law, insofar as such Losses (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a "Violation"): (i) any untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or (ii) the omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation by the Company of the Act, the 1934 Act, any state securities law or rule or regulation promulgated under the Act, the 1934 Act, or any state securities law and the Company will reimburse each such Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or action; provided, however, that the indemnity agreement contained in this subsection 4(a) shall not apply to amounts paid in settlement of any such Loss or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such Loss or action to the extent that it arises out of or is based upon a Violation which occurs (i) in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder Indemnified Person, or (ii) the failure of such Holder Indemnified Person to deliver a copy of the registration statement or the prospectus, or any amendments or supplements thereto, after the Company or underwriters has furnished such person with a sufficient number of copies of the same. (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the "Company Indemnified Persons" (defined for the purpose of this Section 4 as the Company, each of its directors in their capacity as such, each of its officers who have signed the registration statement in their capacity as such, each person, if any, who controls the Company within the meaning of the Act in their capacity as such, any underwriter and any other Holder Indemnified Person selling securities in such registration statement), against any Loss (joint or several) to which the Company or any such director, officer, controlling person, or underwriter or controlling person, or other such Holder Indemnified Person may become subject, under the Act, the 1934 Act or other federal or state law, insofar as such Loss (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company and any such Company Indemnified Person in connection with investigating or defending any such Loss or action; provided, however, that the indemnity agreement contained in this subsection 4(b) shall not apply to amounts paid in settlement of any such Loss or action if such settlement is effected without the consent of the Holder (which consent shall not be unreasonably withheld); provided, that, in no event shall any indemnity under this subsection 4(b) exceed the gross proceeds from the offering received by such Holder. 81 4 (c) Promptly after receipt by an indemnified party under this Section 4 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 4, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the reasonably incurred fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding; provided, further, that the indemnifying party shall be responsible for the fees and expenses incurred by only one (1) counsel for all indemnified parties. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 4, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 4. (d) If the indemnification provided for in this Section 4 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any Loss, then the indemnifying party, in lieu of indemnifying the indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such Loss in such proportion as such court finds appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other, in connection with the statements or omissions that resulted in such Loss as well as any other relevant equitable considerations. The relative fault of the indemnifying party and the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. (e) The obligations of the Company and Holders under this Section 4 shall survive the completion of any offering of Warrant Shares in a registration statement under this Agreement. 5. FURNISH INFORMATION. It shall be condition precedent to the obligations of the Company to take any action pursuant to this Agreement that the selling Holders shall timely furnish to the Company such information regarding themselves, the Warrant Shares held by them, and the intended method of disposition of such securities as shall be required to effect the registration of their Warrant Shares or to determine that registration is not required pursuant to Rule 144 or other applicable provision of the Act, as well as to execute any agreements as may be reasonably requested by the Company in connection therewith. 6. MISCELLANEOUS 82 5 (a) Company use its best efforts to maintain any registration statement filed under this Agreement effective as provided above until the distribution described in that registration statement has been completed or the Securities are sold pursuant to Rule 144 of the Securities Act of 1933. (b) Each Holder shall give the Company one business day's prior written notice of any proposed sale of Warrant Shares under the registration statement, and shall not make such sale unless (i) one business day lapses without response from the Company, or (ii) the Company notifies the Holder in writing that the registration statement requires a post-effective amendment or supplement to be current. In the event of (ii) above, and subject to section 4 above, the Company shall use its reasonable efforts to file a complete and accurate post-effective amendment or supplement with the SEC and have any such amendment declared effective as soon as reasonably possible and provide copies to the Holders to enable them to sell their Warrant Shares in accordance with applicable law and regulations. (c) Any provision of this Agreement may be amended and the observance thereof may be waived only with the written consent of the Company and the Holders of a majority of the Warrant Shares. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each Holder, each future Holder, and the Company. The undersigned acknowledge that Holders of the Warrant Shares are third party beneficiaries of this Agreement.

Any notice, except as otherwise provided in this Agreement, shall be made by fax and shall be deemed given at the time of transmission of the fax.

(f) The rights of a Holder under this Agreement may be transferred to a subsequent holder of the Holder's Warrant Shares (provided such transferee shall provide to the Company, together with or prior to such transferee's request to have such Registrable Shares included in a Demand Registration or Piggyback Registration, a copy of this Agreement executed by such transferee agreeing to be bound as a Holder by the terms of this Agreement). (g) This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, U.S.A. applicable to agreements made in and wholly to be performed in that jurisdiction, except for matters arising under the Act or the Securities Exchange Act of 1934, which 83 6 matters shall be construed and interpreted in accordance with such laws.
