SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED OR PLEDGED IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL (WHICH MAY BE COUNSEL FOR THE COMPANY) REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT." "THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY." Each Investor and Holder consents to the Company making a notation on its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer established in this Section 1. 1.4 Notice of Proposed Transfers. The holder of each certificate ---------------------------- representing Restricted Securities, by acceptance thereof, agrees to comply in all respects with the provisions of this Section 1. Prior to any proposed sale, assignment, transfer or pledge of any Restricted Securities, unless there is in effect a registration statement under the Securities Act covering the proposed transfer, the holder thereof shall give written notice to the Company of such holder's intention to effect such transfer, sale, assignment or pledge. Each such notice shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge in sufficient detail, and shall be accompanied at such holder's expense by either (i) an unqualified written opinion of legal counsel who shall be, and whose legal opinion shall be, reasonably satisfactory -3- to the Company, addressed to the Company, to the effect that the proposed transfer of the Restricted Securities may be effected without registration under the Securities Act, or (ii) a "no action" letter from the Commission to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice delivered by the holder to the Company. The Company will not require such a legal opinion or "no action" letter (a) in any transaction in compliance with Rule 144, (b) in any transaction in which an Investor which is a corporation distributes Restricted Securities solely to its majority-owned subsidiaries or affiliates for no consideration, or (c) in any transaction in which an Investor which is a partnership distributes Restricted Securities solely to partners or retired partners thereof for no consideration, provided that each transferee agrees in writing to be subject to the terms of this Section 1.4. Each certificate evidencing the Restricted Securities transferred as above provided shall bear, except if such transfer is made pursuant to Rule 144, the appropriate restrictive legend set forth in Section 1.3 above, except that such certificate shall not bear such restrictive legend if, in the opinion of counsel for such holder and the Company, such legend is not required in order to establish compliance with any provisions of the Securities Act. The Company shall be required to promptly reissue unlegended certificates at the request of any holder thereof if the Holder shall have obtained an opinion of counsel who shall be, and whose legal opinion shall be, reasonably acceptable to the Company, at such Holder's expense, to the effect that the securities proposed to be disposed of may lawfully be so disposed of without registration, qualification or legend. Notwithstanding the foregoing, a legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal. 1.5 Requested Registration. ---------------------- (a) Request for Registration. In case the Company shall receive from ------------------------ Holders of at least forty percent (40%) of the Registrable Securities a written request that the Company effect any registration, qualification or compliance of the Registrable Securities, the anticipated aggregate offering price to the public of which would exceed $5,000,000, the Company will: (i) promptly give written notice of the proposed registration, qualification or compliance to all other Holders; and (ii) as soon as practicable, use its best efforts to effect such registration, qualification or compliance (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky law or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within twenty (20) days after receipt of such written -4- notice from the Company by any Holder; provided, however, that the Company shall -------- ------- not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 1.5: (1) In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; (2) Prior to the earlier of December __ , 2000 or six (6) months following the bona fide firm commitment underwritten (by an underwriter of nationally recognized standing) initial public offering of the Company's Common Stock pursuant to an effective registration statement under the Securities Act; (3) If at the time of the request to register Registrable Securities the Company gives notice within thirty (30) days of such request that it is engaged or has fixed plans to engage within ninety (90) days of the time of the request in a bona fide firm commitment underwritten public offering of its Common Stock pursuant to an effective registration statement under the Securities Act; (4) After the Company has effected two (2) such registrations pursuant to this subparagraph 1.5(a), such registrations have been declared or ordered effective and the securities offered pursuant to such registrations have been sold; or (5) If the Company shall furnish to such Holders a certificate, signed by the President of the Company, stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its shareholders for registration statements to be filed in the near future, then the Company's obligation to use it best efforts to register, qualify or comply under this Section 1.5 shall be deferred for up to one (1) period, not to exceed one hundred twenty (120) days each from the date of receipt of written request from the Holders, in any twelve (12) month period. Subject to the foregoing clauses (1) through (5), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. (b) Underwriting. In the event that a registration pursuant to ------------ Section 1.5 is for a registered public offering involving an underwriting, the Company shall so advise the Holders as part of the notice given pursuant to Section 1.5(a)(i). The right of any Holder to registration pursuant to Section 1.5 shall be conditioned upon such Holder's participation in the underwriting arrangements required by Section 1.5 and the inclusion of such Holder's Registrable Securities in the underwriting, to the extent requested and to the extent provided in this Agreement. The Company shall (together with all Holders) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by majority in interest of the Holders requesting such registration (which managing underwriter -5- shall be reasonably acceptable to the Company). Notwithstanding any other provision of this Section 1.5, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities to be included in such registration. The Company shall so advise all Holders, and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all such Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing the registration statement. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. If any Holder disapproves of the terms of any such underwriting, he or she may elect to withdraw therefrom by written notice to the Company and the managing underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration, and shall not be transferred in a public distribution prior to 180 days after the effective date of the registration statement relating thereto. 1.6 Company Registration. -------------------- (a) Notice of Registration. If at any time or from time to time, the ---------------------- Company shall determine to register any of its securities, either for its own account or the account of a security holder or holders other than (i) a registration relating solely to employee benefit plans, or (ii) a registration relating solely to a Commission Rule 145 transaction, the Company will: (i) give to each Holder written notice thereof; and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved in such registration, all the Registrable Securities specified in a written request or requests made within twenty (20) days after receipt of such written notice from the Company by any Holder. (b) Underwriting. If the registration of which the Company gives ------------ notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as part of the written notice given pursuant to Section 1.6(a)(i). In such event, the right of any Holder to registration pursuant to Section 1.6 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company (or the Holders who have demanded such registration). Notwithstanding any other provision of this Section 1.6, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities to be included in such registration provided, however, that, except in the case of the initial public offering of the Company's Common Stock pursuant to a registration statement under the Securities Act (where securities (including Registrable Securities) to be included in such registration by the Company's shareholders (including the Holders) may be excluded entirely if the managing underwriter determines that marketing factors require a -6- limitation of the number of shares to be underwritten), the aggregate value of securities (including Registrable Securities) to be included in such registration by the Company's shareholders (including the Holders) may not be so reduced to less than thirty percent (30%) of the total value of all securities included in such registration. The Company shall so advise all Holders, and the number of shares Registrable Securities that may be included in the registration and underwriting shall be allocated among all such Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing the registration statement. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. If any Holder disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company and the managing underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration, and shall not be transferred in a public distribution prior to 180 days after the effective date of the registration statement relating thereto. (c) Right to Terminate Registration. The Company shall have the right ------------------------------- to terminate or withdraw any registration initiated by it under this Section 1.6 prior to the effectiveness of such registration, whether or not any Holder has elected to include securities in such registration. 1.7 Registration on Form S-3. ------------------------ (a) If Holders of at least thirty percent (30%) of the Registrable Securities then outstanding request that the Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of shares of the Registrable Securities, the reasonably anticipated aggregate price to the public of which would exceed $1,000,000, and the Company is a registrant entitled to use Form S-3 to register the Registrable Securities for such an offering, the Company shall use its best efforts to cause such Registrable Securities to be registered for the offering on such form; provided, -------- however, that the Company shall not be required to effect more than two (2) - ------- registrations, and provided, further, that the Company shall not be required to -------- ------- pay Registration Expenses incurred in connection with more than one (1) registration pursuant to this Section 1.7 in any twelve (12) month period. The Company will (i) promptly give written notice of the proposed registration to all other Holders, and (ii) as soon as practicable, use its best efforts to effect such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within twenty (20) days after receipt of such written notice from the Company. (b) Notwithstanding the foregoing, the Company shall not be obligated to take any action pursuant to this Section 1.7: (i) in any particular jurisdiction in which the Company -7- would be required to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act, (ii) during the period starting with the date sixty (60) days prior to the filing of, and ending on a date six (6) months following the effective date of, a registration statement (other than with respect to a registration statement relating to a Rule 145 transaction, an offering solely to employees or any other registration which is not appropriate for the registration of Registrable Securities), provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective, or (iii) if the Company shall furnish to such Holder a certificate signed by the president of the Company stating that, in the good faith judgment of the Board of Directors, it would be seriously detrimental to the Company or its shareholders for registration statements to be filed in the near future, then the Company's obligation to register, qualify or comply under this Section 1.7 shall be deferred for up to one (1) period, not to exceed one hundred twenty (120) days each from the receipt of the request to file such registration by such Holder or Holders, in any twelve (12) month period. 1.8 Expenses of Registration. Subject to the limitation set forth in ------------------------ Section 1.7, all Registration Expenses incurred in connection with any registration pursuant to Sections 1.5, 1.6 and 1.7 and the reasonable cost of one (1) special legal counsel to represent all of the Holders together in any such registration shall be borne by the Company. Unless otherwise stated, all other Selling Expenses relating to securities registered on behalf of the Holders shall be borne by the Holders of the registered securities included in such registration pro rata on the basis of the number of shares so registered. 1.9 Registration Procedures. In the case of each registration, ----------------------- qualification or compliance effected by the Company pursuant to this Section 1, the Company will keep each Holder advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense the Company will: (a) Prepare and file with the Commission a registration statement with respect to such securities and use its best efforts to cause such registration statement to become and remain effective for at least one hundred eighty (180) days or until the distribution described in the registration statement has been completed;

(e) promptly notify each Holder selling Registrable Securities covered by such registration statement and each managing underwriter, if any: (i) when the registration statement, any pre-effective amendment, the prospectus or any prospectus supplement related thereto or post-effective amendment to the registration statement has been filed and, with respect to the registration statement or any post-effective amendment, when the same has become effective;

and, if the notification relates to an event described in clause (v), the Company shall promptly prepare and furnish to each such seller and each underwriter, if any, a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein in the light of the circumstances under which they were made not misleading;

(b) Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter, if any, of the Company's securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Holder, each of its officers and directors and each person controlling such Holder within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and, only out of the net proceeds received by such Holder from the offering of the securities covered by such a registration statement, will reimburse the Company, such Holders, such directors, officers, persons, underwriters or control persons for any legal or any other expenses as reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Holder and stated to be specifically for use therein. In no event shall any indemnity under this Section 1.10(b) exceed the net proceeds from the offering received by such Holder. (c) Each party entitled to indemnification under this Section 1.10 (the "Indemnified Party") shall give notice to the party required to provide ----------------- indemnification (the "Indemnifying Party") promptly after such Indemnified Party ------------------ has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved -12- by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party's expense, and provided further that (i) if the Indemnifying Party fails to take reasonable steps necessary to defend diligently the action or proceeding within twenty (20) days after receiving notice from such Indemnified Party; or (ii) if such Indemnified Party who is a defendant in any action or proceeding which is also brought against the Indemnifying Party reasonably shall have concluded that there may be one or more legal defenses available to such Indemnified Party which are not available to the Indemnifying Party; or (iii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the Indemnified Party shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all Indemnified Parties in each jurisdiction), and the Indemnifying Party shall be liable for any expenses therefor. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 1 unless the failure to give such notice is materially prejudicial to an Indemnifying Party's ability to defend such action. No settlement of any such claim, loss, damage, liability or action shall be made by the Indemnified Party without the prior written consent of the Indemnifying Party (such consent to not be unreasonably withheld). No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (d) If for any reason the foregoing indemnity is unavailable or is insufficient to hold harmless an Indemnified Party under Sections 1.10(a) or (b), then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of any Claim in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, with respect to such offering of securities. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged 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 untrue statement or omission. If, however, the allocation provided in the second preceding sentence is not permitted by applicable law, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party in such proportion as is appropriate to reflect not only such relative faults but also the relative benefits of the Indemnifying Party and the Indemnified Party as well as any other relevant equitable considerations. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 1.10(d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the preceding sentences of this Section 1.10(d). The amount paid or payable in respect of any Claim shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such Claim. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding anything in this Section 1.10(d) to the contrary, no -13- Indemnifying Party (other than the Company) shall be required pursuant to this Section 1.10(d) to contribute any amount in excess of the net proceeds received by such indemnifying party from the sale of Registrable Securities in the offering to which the Claims of the Indemnified Parties relate, less the amount of any indemnification payment made by such Indemnifying Party pursuant to Section 1.10(b). (e) The indemnification and contribution agreements contained herein shall be in addition to any other rights to indemnification or contribution which any Indemnified Party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made or omitted by or on behalf of any Indemnified Party and shall survive the transfer of the Registrable Securities by any such party. (f) The indemnification and contribution required by this Section 1.10 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred. 1.11 Information by Holder. The Holder or Holders of Registrable --------------------- Securities included in any registration shall furnish to the Company such information regarding such Holder or Holders, the Registrable Securities held by them and the distribution proposed by such Holder or Holders as the Company may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Section 1. 1.12. Limitations on Subsequent Registration Rights; No Inconsistent -------------------------------------------------------------- Agreements. Without the prior written consent of the Holders of a majority of - ---------- the Registrable Securities, the Company will not, on or after the date of this Agreement, enter into any agreement with respect to its securities with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights, the terms of which are more favorable than the registration rights granted to the Holders thereunder. The Company further agrees that if any other registration rights agreement entered into after the date of this Agreement with respect to any of its securities contains terms which are more favorable to, or less restrictive on, the other party thereto than the terms and conditions in this Agreement are (insofar as they are applicable) to the Holders, then the terms and conditions of this Agreement shall immediately be deemed to have been amended without further action by the Company or any of the Holders of Registrable Securities so that the Holders shall be entitled to the benefit of any such more favorable or less restrictive terms or conditions. 1.13 Rule 144 Reporting. With a view to making available the benefits of ------------------ certain rules and regulations of the Commission which may at any time permit the sale of the Restricted Securities to the public without registration, after such time as a public market exists for the Common Stock of the Company, the Company agrees to use its best efforts to: (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date that the Company becomes subject to the reporting requirements of the Securities Act or the Securities Exchange Act of 1934, as amended (the "Exchange Act"); ------------ -14- (b) File with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and (c) So long as an Investor owns any Restricted Securities, to furnish to the Investor forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company and other information as an Investor may reasonably request in availing itself of any rule or regulation of the Commission allowing an Investor to sell any such securities without registration. 1.14 Transfer of Registration Rights. The rights to cause the Company to ------------------------------- register securities granted Investors under Sections 1.5, 1.6 and 1.7 may be assigned to a transferee or assignee reasonably acceptable to the Company in connection with any transfer or assignment of Registrable Securities by an Investor (together with any affiliate); provided, that (a) such transfer may -------- otherwise be effected in accordance with applicable securities laws, (b) notice of such assignment is given to the Company, and (c) such transferee or assignee (i) is a wholly-owned subsidiary or constituent partners (including limited partners) of such Investor, or (ii) acquires from such Investor the lesser of (A) 100,000 or more shares of Restricted Securities (as appropriately adjusted for stock splits, stock dividends and the like) or (B) all of the Restricted Securities then owned by such Investor. 1.15 Standoff Agreement. Each Holder agrees in connection with any ------------------ registration of the Company's securities, upon request of the Company or the underwriters managing any underwritten offering of the Company's securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Securities (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty (180) days from the effective date of such registration in the case the initial public offering of the Company's Common Stock pursuant to a registration statement under the Securities Act and ninety (90) days in any subsequent offering) as may be requested by the Company or such managing underwriters; provided, that (a) the officers and directors of the Company who -------- own stock of the Company (and "affiliates" and "associates" thereof (as such terms are defined in Rule 12b 2 under the Exchange Act) agree to such restrictions, and (b) the Company has used commercially reasonable efforts to cause shareholders holding over 200,000 shares of Common Stock or Common Stock equivalents to agree to such restrictions. 1.16 Termination of Rights. The rights of any particular Holder to cause --------------------- the Company to register securities under Sections 1.5, 1.6 and 1.7 shall terminate with respect to such Holder (i) five (5) years following a bona fide firm underwritten public offering of shares of the Company's Common Stock registered under the Securities Act, (ii) with respect to any Holder, at such time as such Holder is able to dispose of all its Registrable Securities in one three (3)-month -15- period pursuant to the provisions of Rule 144; or (iii) with respect to any Holder, at such time as such Holder holds Registrable Securities constituting less than one percent (1%) of the outstanding voting stock of the Company. SECTION 2 Affirmative Covenants of the Company The Company hereby covenants and agrees as follows: 2.1 Financial Information. As long as a Holder holds at least 500,000 --------------------- shares of the Securities (as adjusted for stock splits, stock dividends and the like), the Company will mail the following reports to such Holder: (a) As soon as practicable after the end of each fiscal year, and in any event within ninety (90) days thereafter, audited consolidated balance sheets of the Company and its subsidiaries, if any, as of the end of such fiscal year, and audited consolidated statements of income, audited consolidated statements of changes in financial position and audited consolidated statements of shareholders' equity of the Company and its subsidiaries, if any, for such year, prepared in accordance with generally accepted accounting principles consistently applied and setting forth in each case in comparative form the figures for the previous fiscal year, all in reasonable detail and certified by independent public accountants of recognized national standing selected by the Company. (b) As soon as practicable after the end of the first, second and third quarterly accounting periods in each fiscal year of the Company and in any event within forty-five (45) days thereafter, an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such quarterly period, and unaudited consolidated statements of income, unaudited consolidated statements of cash flow and unaudited consolidated statements of shareholders' equity of the Company and its subsidiaries, if any, for such period and for the current fiscal year to date, and comparisons to budget and the corresponding prior year period, prepared in accordance with generally accepted accounting principles (other than for accompanying notes and subject to normal year-end audit adjustments), all in reasonable detail. (c) As soon as practicable after the end of each month (other than the last month of a fiscal quarter) and in any event within forty-five (45) days after the end of each such month through November 30, 1998 and within thirty (30) days after the end of each such month thereafter, an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such month, and unaudited consolidated statements of income, unaudited consolidated statements of cash flow and unaudited consolidated statements of shareholders' equity of the Company and its subsidiaries, if any, for such month and for the current fiscal year to date, and comparisons to budget and the corresponding prior year period, prepared in accordance with generally accepted accounting principles (other than for accompanying notes and subject to normal year-end audit adjustments), all in reasonable detail. -16- (d) As soon as practicable, but in any event not less than thirty (30) days nor more than ninety (90) days prior to the end of each fiscal year, a budget and business plan for the next fiscal year, prepared on a monthly basis, including balance sheets and sources and applications of funds statements for such months and, as soon as prepared, any other budgets or revised budgets prepared by the Company. (e) Contemporaneously with delivery to holders of Common Stock, a copy of each report of the Company delivered to holders of the Company's Common Stock. 2.2 Subsidiaries. If for any period the Company shall have any subsidiary ------------ or subsidiaries whose accounts are consolidated with those of the Company, then, in respect of such period, the financial statements and information delivered pursuant to the foregoing Section 2.1 shall be the consolidated and consolidating financial statements of the Company and all such consolidated subsidiaries. 2.3 Access to Records. ----------------- (a) Each Holder shall have access to the Company's books, records and properties for purposes reasonably related to such Holder's interests as a shareholder. (b) The Company shall afford each Holder of at least 500,000 shares of Series D Preferred Stock and/or Series E Preferred Stock (a "Major Holder"), ------------ and their employees, counsel and other authorized representatives full access, during normal business hours, upon reasonable advance notice, with due regard to its ongoing operations, to the assets, properties, plants, offices, warehouses and other facilities, contracts and books and records of the Company, and to the outside auditors of the Company and their work papers relating thereto, in each case, as the Major Holders may from time to time reasonably request. The Major Holders and their representatives shall be entitled to consult with the representatives, officers, employees and accountants of the Company with respect to the Company, and the Company will instruct such persons to cooperate with the Major Holders. The Company shall permit representatives of the Major Holders to discuss the affairs, finances and accounts of the Company with, and to make proposals and furnish advice with respect thereto to, the principal officers of the Company, all at such reasonable times, upon reasonable notice and as often as the Major Holders may reasonably request; provided, however, that neither the Board of Directors nor the officers of the Company shall be under any obligation pursuant to this Section 2.3 to take any action with respect to any proposals made or advice furnished by the Major Holders in their capacities as shareholders of the Company, other than to take such proposals or advice seriously and give due consideration thereto. (c) The Company agrees to furnish to each Major Holder, within ten (10) business days of any Major Holder's request, a capitalization table setting forth the class, series of each class, the name of the holder of each class or series thereof, and the number of shares held by each such holder. 2.4 System of Accounting. The books of account and other financial and -------------------- corporate records of the Company shall be maintained in accordance with good business and accounting -17- practices and the financial condition of the Company shall be accurately reflected in the financial statements required to be provided to the Major Holders under the terms of this Agreement. 2.5 Transfer of Information Rights.

Subject to the terms and conditions -------------------------- specified in this Section 2.6, the Company hereby grants to each Major Holder a right to maintain the percentage ownership interest of such Major Holder in the Company with respect to future sales by the Company of any shares of, or securities convertible into or exercisable for any shares of, any class of its capital stock ("Shares"), such that each time the Company proposes to offer ------ Shares, the Company shall first make an offering of such Shares to each Major Holder in accordance with the following provisions: (a) The Company shall deliver a notice by certified mail ("Notice") ------ to each Major Holder stating the aggregate number of such Shares to be offered and the price and terms upon which it proposes to offer such Shares.

(c) The Company may, during the ninety (90)-day period following the expiration of the period provided in Section 2.6(b), offer the remaining unsubscribed portion of -18- the Shares to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the Notice.
