January 30, 1998 STOCK PURCHASE AGREEMENT This Agreement ("Agreement") is made on January 30, 1998, between SPARTECH CORPORATION, a Delaware corporation ("Buyer"), RBA PARTNERS, L.P., a Pennsylvania limited partnership ("RBA"), BANBURY ASSOCIATES, L.P., a Pennsylvania limited partnership ("Banbury"), HUNTSMAN COMPOUNDING COMPANY, LC, a Utah limited liability company ("HCC"), and THE JON AND KAREN HUNTSMAN FOUNDATION, a Utah nonprofit corporation ("HF" and, collectively with RBA, Banbury, and HCC, "Sellers"). PREAMBLE Sellers desire to sell, and Buyer desires to purchase, all of the issued and outstanding shares (the "Shares") of capital stock of Polycom Huntsman, Inc., a Pennsylvania corporation (the "Company"), for the consideration and on the terms set forth in this Agreement. NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties, intending to be legally bound hereby, agree as follows: ARTICLE I SALE AND TRANSFER OF SHARES; CLOSING Section 1.1. Purchase and Sale. On the terms and subject to the conditions of this Agreement, at the Closing (as defined in Section 1.2), Sellers shall sell and transfer the Shares to Buyer, and Buyer shall purchase the Shares from Sellers, for an aggregate purchase price of $135,000,000 (the "Purchase Price"), payable as set forth in Section 1.3(b) and subject to adjustment as set forth in Sections 1.4 and 1.5. The purchase and sale of the Shares is referred to in this Agreement as the "Acquisition." Section 1.2. Closing. The closing of the Acquisition (the "Closing") shall take place at the offices of Cohen & Grigsby, P.C., at 10:00 a.m. on March 24, 1998 or, if on such day any condition set forth in Section 5.1, Section 5.2 or Section 5.3 has not been satisfied (or, to the extent permitted, waived by the parties entitled to the benefit thereof), as soon as practicable after all the conditions set forth in Article V have been satisfied (or, to the extent permitted, waived by the parties entitled to the benefits thereof), or at such other place, time, and date as may be agreed between Sellers and Buyer. The date on which the Closing occurs is referred to in this Agreement as the "Closing Date." Section 1.3. Closing Obligations. At the Closing: (a) Sellers will deliver to Buyer: (i) certificates representing the Shares, duly endorsed (or accompanied by duly executed stock powers), for transfer to Buyer; and (ii) such other documents as Buyer or its counsel may reasonably request to demonstrate satisfaction of the conditions and Sellers' compliance with the covenants set forth in this Agreement. (b) Buyer will deliver to Sellers: (i) $125,000,000 of the Purchase Price in immediately available funds as set forth in Schedule 1.3 of the Disclosure Schedule (as hereinafter defined); (ii) certificates representing that number of whole shares of unregistered common stock of Buyer ("Spartech Stock") equal to the quotient obtained by dividing $10,000,000 by the Per Share Value (determined as hereinafter provided), duly endorsed (or accompanied by duly executed stock powers) for transfer to Sellers in the following proportions, rounded down to the nearest whole share as set forth in Schedule 1.3 of the Disclosure Schedule. Because the Shares are unregistered, Buyer has agreed to provide Sellers with certain registration rights, as more fully described in the Registration Agreement attached hereto as Exhibit A. As used herein, the term "Per Share Value" means the arithmetic average of the Market Prices per share of Spartech Stock for the 20 consecutive Trading Days immediately preceding the date hereof. The term "Market Price" for any Trading Day shall mean the closing sale price for Spartech Stock on such day as published by the New York Stock Exchange ("NYSE"). The term "Trading Day" shall mean any day on which trading takes place and prices reflecting such trading are generally published by the NYSE. Notwithstanding any contrary provisions of this Agreement, if the calculation under this subparagraph requires a fractional share to reach the sum of $10,000,000, no such fractional share shall be issued but the value of such fractional share shall be paid in cash to Sellers in the above specified proportions at the Closing; and (iii) such other documents as Sellers or their counsel may reasonably request to demonstrate satisfaction of the conditions and Buyer's compliance with the covenants set forth in this Agreement. Section 1.4. Adjustment Amount. The Adjustment Amount (which may be a positive or negative number) will be equal to (a) the stockholders' equity of the Company and its Subsidiaries (as defined in Section 2.1) as of the Closing Date determined in accordance with generally accepted United States accounting principles ("GAAP"), applied on a basis consistent with the basis on which the Audited Financial Statements (as defined in Section 2.5) and the other financial statements of the Company were prepared, minus (b) $57,731,000, being the estimated stockholders' equity of the Company and its Subsidiaries as of December 31, 1997. Section 1.5. Adjustment Procedure. (a) Sellers will prepare and will cause Ernst & Young, the Company's certified public accountants, to audit financial statements ("Closing Financial Statements") of the Company as of the Closing Date and for the period from the date of the Audited Financial Statements (as defined in Section 2.5) through the Closing Date, including a computation of stockholders' equity as of the Closing Date. Sellers will deliver the Closing Financial Statements to Buyer within sixty days after the Closing Date. During the thirty day period following the delivery of the Closing Financial Statements, Buyer and its auditors shall have access to the working papers of the Company's auditors prepared in connection with the Closing Financial Statements. If within thirty days following delivery of the Closing Financial Statements, the Buyer has not given the Sellers written notice of its objection to the Closing Financial Statements (a "Notice of Objection"), then the stockholders' equity reflected in the Closing Financial Statements will be used in computing the Adjustment Amount. To be effective, a Notice of Objection shall (i) specify in reasonable detail the nature of any disagreement so asserted, (ii) only include disagreements based on mathematical errors or based on stockholders' equity of the Company and its Subsidiaries not being calculated in accordance with Section 1.4 and this Section 1.5 and (iii) be accompanied by a certificate of Buyer's independent auditors that they concur with each of the positions taken by Buyer in the Notice of Objection. During the 30 day period following the delivery of a Notice of Objection, Sellers and Buyer shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Objection. During such period Sellers and their auditors shall have access to the working papers of Buyer's auditors prepared in connection with their certification of the Notice of Objection. At the end of such 30-day period, Sellers and Buyer shall submit to an independent accounting firm (the "Accounting Firm") for arbitration any and all matters that remain in dispute and which were properly included in the Notice of Objection. Sellers and Buyer agree to use reasonable efforts to cause the Accounting Firm to render a decision resolving the matters submitted to the Accounting Firm within 30 days following submission. If issues in dispute are submitted to the Accounting Firm for resolution, (i) each party will furnish to the Accounting Firm such workpapers and other documents and information relating to the disputed issues as the Accounting Firm may request and are available to that party or its Subsidiaries (or its independent public accountants), and will be afforded the opportunity to present to the Accounting Firm any material relating to the determination and to discuss the determination with the Accounting Firm; (ii) the determination by the Accounting Firm, as set forth in a notice delivered to both parties by the Accounting Firm, will be binding and conclusive on the parties; and (iii) Buyer and Sellers will each bear 50% of the fees of the Accounting Firm for such determination. (b) On the third business day following the final determination of the Adjustment Amount, if the Adjustment Amount is greater than zero, then Buyer will pay the Adjustment Amount to Sellers, and if the Adjustment Amount is less than zero, then Sellers will pay the Adjustment Amount to Buyer, and in such case, Sellers shall be jointly and severally liable to Buyer for such negative Adjustment Amount. All payments will be made together with interest at the rate of interest announced from time to time by Bank of America as its prime rate beginning on the Closing Date and ending on the date of payment. Payments must be made in immediately available funds. Payments to Sellers must be made in the manner and will be allocated in the proportions set forth in Section1.3(b)(i). Payments to Buyer must be made by wire transfer to such bank account as Buyer will specify. (c) Following the Closing, Buyer shall not take any actions with respect to the accounting books and records of the Company on which the Closing Financial Statements are to be based that would obstruct or prevent the preparation of the Closing Financial Statements and the determination of stockholders' equity as provided in Sections 1.4 and 1.5. During the period of time from and after the date of delivery of the Closing Financial Statements to Buyer through the date on which the Closing Financial Statements become final and binding on the parties, Buyer shall afford to Sellers and any accountants, counsel, or financial advisers retained by Sellers in connection with the Closing Financial Statements reasonable access during normal business hours to the books and records of the Company to the extent relevant to the adjustment contemplated by Section 1.4 and Section 1.5. ARTICLE II REPRESENTATIONS AND WARRANTIES OF THE SELLERS Except as otherwise disclosed in Schedules 2.1 through 2.27 (collectively, the "Disclosure Schedule") (which Disclosure Schedule may be amended by Sellers at any time prior to consummation of the Closing, as further provided in Section 5.2(e)), Sellers, jointly but not severally, hereby represent and warrant to Buyer, as of the date of this Agreement and as of the Closing Date, as follows: Section 2.1.

Section 7.3. Procedure for Indemnification. (a) If any party hereto shall claim indemnification hereunder arising from any claim or demand of a third party, the party seeking indemnification (the "indemnitee") shall promptly notify the party or parties from whom indemnification is sought (the "indemnitor") in writing of the basis for such claim or demand, setting forth the nature of the claim or demand in reasonable detail; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnitor shall have been prejudiced as a result of such failure (except that the indemnitor shall in no event be liable for any expenses incurred during the period in which the indemnitee failed to give such notice). Thereafter, the indemnitee shall deliver to the indemnitor, promptly following the indemnitee's receipt thereof, copies of all notices and documents (including court papers) received by the indemnitee relating to the third-party claims other than those notices and documents (including court papers) received by the indemnitee relating to the third-party claim other than those notices and documents separately addressed to the indemnitor. The indemnitor shall have the right to compromise or, if appropriate, defend at its own cost and through counsel of its own choosing, any claim or demand of any third party giving rise to such claim for indemnification. Such notice and opportunity to compromise or defend, if applicable, shall be conditions precedent to any asserted liability under this indemnity. In the event the indemnitor undertakes to compromise or defend any such claim or demand, it shall promptly notify the indemnitee in writing of its intention to do so. The indemnitee shall fully cooperate with the indemnitor and its counsel in the defense or compromise of such claim or demand. Such cooperation shall include the retention and (upon the indemnitor's reasonable request) the provision to the indemnitor of records and information that are reasonably relevant to such third-party claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. After the assumption of the defense by the indemnitor, the indemnitor shall not be liable for any legal or other expenses subsequently incurred by the indemnitee in connection with such defense, but the indemnitee may participate in such defense at its own expense, it being understood that the indemnitor shall control such defense. No settlement of a third party claim or demand defended by the indemnitee shall be made without the written consent of the indemnitor. The indemnitor shall not, except with the written consent of the indemnitee, consent to the entry of a judgment or settlement which does not include, as an unconditional term thereof, the giving by the claimant or plaintiff to the indemnitee of an unconditional release from all liability in respect of such third party claim or demand. The indemnitor shall be liable for fees and expenses of counsel employed by the indemnitee for any period during which the indemnitor has not assumed the defense thereof (other than during any period in which the indemnitee shall have failed to give notice of the third-party claim as provided above). (b) If any party shall claim indemnification hereunder for any claim other than third party claims, the indemnitee shall promptly notify the indemnitor in writing of the basis for such claim, setting forth the nature and amount of the claim in reasonable detail; and after determination of the validity of such claim, which the parties shall promptly pursue, payment therefor shall be made by the indemnitor. Section 7.4. Period of Indemnity. The indemnities contained in this Article VII shall expire one year from the Closing Date, except with respect to (i) the untruth, inaccuracy or breach of any representation or warranty of Sellers contained in Section 2.11 (Taxes), in which case the indemnification period shall be extended until the running of the statute of limitations applicable to the taxable period to which a particular claim relates; or Section 2.16 (Environmental Laws and Regulations) of this Agreement, in which case the indemnification period shall be extended to two (2) years from the Closing Date and (ii) Buyer's Losses or Sellers' Losses as to which notice has been given pursuant to Section 7.3 within such period, in which case the indemnification period shall be extended until final resolution of such Loss. Section 7.5. Limitation of Liability. The obligations and liabilities of Buyer and Sellers for indemnification hereunder shall be subject to the following limitations: (a) Buyer's right to indemnification under this Article VII shall be limited to a maximum recovery from Sellers of an amount equal to Ten Million ($10,000,000) Dollars and Buyer agrees this shall constitute Buyer's sole and exclusive remedy with respect to Buyer's Losses or otherwise with respect to this Agreement and the transactions contemplated herein. (b) No indemnification shall be required to be made by Sellers under this Article VII unless the aggregate amount of Buyer's Losses exceeds an amount equal to One Million ($1,000,000) Dollars (the "Threshold"); provided, however, that once the aggregate of all Buyer's Losses exceeds the Threshold, Buyer may claim, and Sellers shall be liable for, 50% of all Buyer's Losses up to the Threshold (and 100% of Buyer's Losses exceeding the Threshold); and provided further, that any Loss arising under clauses 7.1(b), 7.1(c) or 7.1(d), shall be indemnifiable without regard to the Threshold. Section 7.6. Exclusive Remedy; Survival. The parties hereto agree that the remedies provided by this Article VII shall be exclusive with respect to this Agreement and the transactions contemplated herein, the matters described in Sections 7.1 and 7.2 and that the representations and warranties of Buyer and Sellers shall survive only to the extent provided in Section 7.4. Section 7.7. Exclusion of Certain Damages. Notwithstanding any other provision hereof, in no event shall Sellers be liable for or obligated to indemnify Buyer from and against any consequential, indirect or special damages, including, without limitation, lost profits, business interruption and loss of business opportunities or goodwill. This exclusion of any such consequential, indirect or special damages shall apply whether the action in which recovery of damages is sought is based on contract, tort (including sole, concurrent or other negligence or strict liability), statute or otherwise. To the extent permitted by law, any statutory remedies which are inconsistent with this Article VII are waived. ARTICLE VIII MISCELLANEOUS Section 8.1. Amendment and Modification.

The Company and the Shareholders are parties to that certain Stock Purchase Agreement dated as of January 30, 1998 (the "Purchase Agreement"). In order to induce the Shareholders to enter into the Purchase Agreement, the Company has agreed to provide the registration rights set forth in this Agreement. Therefore, the parties agree as follows with the intent to be legally bound: 1. Registration of Shares. (a) At any time after 180 days from the date of this Agreement and prior to the second anniversary thereof, the holders of a majority-in-interest of the shares of common stock of the Company held by the Shareholders (the "Shares") may request, and the Company shall thereupon prepare and file, under the Securities Act of 1933, as amended (the "Act"), a Registration Statement on Form S-3 (the "Registration Statement") covering the Shares requested to be included by all Shareholders in such registration. The registration is intended to qualify as a "shelf" registration as defined in Rule 415(a)(1)(v) of the Act. The term "Shares," as used herein, includes any additional shares which are issued upon any stock dividend on or stock split of the Shares. (b) If the Company is not qualified for the use of Form S-3, the Company agrees to prepare and file, under the Act, a Registration Statement on Form S-1 covering the Shares. (c) Upon receipt of a request for registration under subparagraph 1(a), the Company will give prompt written notice to all holders of Shares of its intention to effect such a registration. The Shareholders will have the right to include in such Registration Statement the number of Shares as each Shareholder may request within 20 days following receipt of such notice. (d) Notwithstanding the foregoing, the Company shall not be required to file a Registration Statement as provided herein at the request of the Shareholders if, at the Company's option and in the written opinion of counsel to the Company which opinion is furnished to the Shareholders, the Shares may be sold by the Shareholders without registration in reliance upon an available exemption under the Act or pursuant to Rule 144 under the Act, as such Rule may be amended from time to time. In any such event, the Company shall, notwithstanding its election to not register the Shares, comply with the requirements of Paragraphs 2(d), (f) and (p) of this Agreement. 2. Registration Procedures. The Company will use its best efforts to effect the registration of the Shares and pursuant thereto the Company will as expeditiously as possible use its best efforts to: (a) prepare and file with the Securities and Exchange Commission (the "Commission") the Registration Statement and use its best efforts to cause such Registration Statement to become and remain effective (provided that before filing the Registration Statement or any prospectus or any amendments or supplements thereto with the Commission, the Company will (i) furnish to the counsel selected by the Shareholders copies of all such documents proposed to be filed which documents will be subject to the review of such counsel, and (ii) notify each Shareholder of any stop order issued or threatened by the Commission); (b) prepare and file with the Commission such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for so long as the Shares are held by the Shareholders, and comply with the provisions of the Act with respect to the disposition of the Shares during such period in accordance with the intended methods of disposition by the Shareholders as set forth in such Registration Statement; (c) furnish to each Shareholder and each underwriter, if any, such number of copies of such Registration Statement, each amendment and supplement thereto, the prospectus included in such Registration Statement (including each preliminary prospectus and prospectus supplement) in conformity with the requirements of the Act, and such other documents as such Shareholder may reasonably request in order to facilitate the disposition of the Shares; (d) when and as applicable, use its best efforts to register and qualify the Shares under such other securities or blue sky laws of such jurisdictions as any Shareholder, and underwriter, if any, reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such Shareholder, and underwriter, if any, to consummate the disposition in such jurisdictions of the Shares (provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph (d), (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction); (e) promptly notify each Shareholder, at any time when a prospectus relating thereto is required to be delivered under the Act, of the receipt by the Company of any notifications with respect to suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose or of the happening of any event which comes to the Company's attention as a result of which the prospectus included in such Registration Statement contains an untrue statement of a material fact or omits any material fact required to be stated therein or necessary to make the statements therein not misleading, and, at the request of any such Shareholder, the Company will promptly prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Shares, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; (f) cause all such Shares to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if not so listed, to be listed on the NASD automated quotation system and, if listed on the NASD automated quotation system, use its reasonable efforts to secure designation of all such Shares covered by such Registration Statement as a NASDAQ "national market system security" within the meaning of Rule 11Aa2-1 under the Securities Exchange Act of 1934, as amended or, failing that, to secure NASDAQ authorization for such Shares and, without limiting the generality of the foregoing, to use its best efforts to arrange for at least two market makers to register as such with respect to such Shares with the NASD;

(i) notify the Shareholders and the underwriters, if any, of the following events and (if requested by any such person) confirm such notification in writing: (1) the filing of the prospectus or any prospectus supplement and the Registration Statement and any amendment or post-effective amendment thereto and, with respect to the Registration Statement and any amendment or posteffective amendment thereto, the declaration of the effectiveness of such documents; (2) any requests by the Commission for amendments or supplements to the Registration Statement or the prospectus or for additional information; (3) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; and (4) the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threat of initiation of any proceeding for such purpose; (j) in the event of the issuance of any stop order suspending the effectiveness of the Registration Statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Shares included in such Registration Statement for sale in any jurisdiction, promptly use its best efforts to obtain the withdrawal of such order; (k) if reasonably requested by any underwriter or Shareholder in connection with any underwritten offering, incorporate in a prospectus supplement or posteffective amendment such information as the underwriters and the Shareholders agree should be included therein relating to the sale of the Shares, including, without limitation, information with respect to the number of Shares being sold to such underwriters, the purchase price being paid therefor by such underwriters and any other terms of the underwritten (or best efforts underwritten) offering of the Shares to be sold in such offering, and make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; (l) cooperate with the Shareholders and the underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Shares to be sold and not bearing any restrictive legends, and enable such Shares to be in such lots and registered in such names as the underwriters may request at least two (2) business days prior to any delivery of Shares to the underwriters; (m) provide a CUSIP number for all Shares not later than the effective date of the Registration Statement; (n) prior to the effectiveness of the Registration Statement and any posteffective amendment thereto and at each closing of an underwritten offering: (1) make such representations and warranties to the underwriters, if any, with respect to the Shares and the Registration Statement as are customarily made by issuers to underwriters in primary underwritten offerings; (2) obtain opinions of counsel to the Company and updates thereof (which opinions shall be reasonably satisfactory to the underwriters, if any) addressed to the underwriters, if any, covering the matters covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by underwriters or their counsel; (3) obtain "cold comfort" letters and updates thereof from the Company's independent certified public accountants addressed to the underwriters, if any, such letters to be in customary form and covering matters of the type customarily covered in "cold comfort" letters to underwriters in connection with primary underwritten offerings; and (4) deliver such documents and certificates as may be reasonably requested by the underwriters, if any, to evidence compliance with clause (1) above and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company; (o) otherwise, comply with all applicable rules and regulations of the Commission, and make generally available to its security holders earnings statements satisfying the provisions of Section 11(a) of the Act and Rule 158 thereunder, no later than forty-five (45) days after the end of any twelve (12) month period or ninety (90) days, if such period is a fiscal year, beginning with the first day of the first fiscal quarter of the Company commencing after the effective date of the Registration Statement; and (p) otherwise comply in all material respects with all applicable rules and regulations of the Commission. All references in this Agreement to information included in the Registration Statement or Prospectus shall include information incorporated by reference in the Registration Statement. 3. Piggyback Registrations. (a) Right to Piggyback. If and whenever, within two years after the date of this Agreement, the Company proposes to register any of its equity securities under the Act (other than pursuant to a demand registration hereunder, a registration relating solely to employee benefit plans, or a registration relating solely to a Rule 145 transaction) and the registration form to be used may be used for the registration of registrable securities (a "Piggyback Registration") the Company shall give prompt written notice as provided in paragraph 3(f) below. Except as provided in paragraphs 3(b), 3(c) and 3(d) below, the Company shall include in any such registration statement all such Shares requested to be included. (b) Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such registration (i) first, the securities the Company proposes to sell, and (ii) second, all shares requested to be included in such registration, pro rata among the holders of such shares on the basis of the number of shares owned by each such holder. (c) Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company's securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering without adversely affecting the marketability of the offering, the Company will include in such registration (i) first, the securities requested to be included therein by the holders requesting such registration and all Shares requested to be included in such registration, pro rata among the holders of such securities on the basis of the number of securities requested to be included therein by each such holder, and (ii) second, other securities requested to be included in such registration. (d) Certain Company Rights. If, at any time after giving written notice of its intention to register any of its securities as set forth in paragraph 3(a) and prior to the Effective Date (as the term "Effective Date" is defined in Rule 158(c) of the Act) of the registration statement filed in connection with such registration, the Company acting in good faith shall determine for sound and substantiated business reasons not to register such securities, the Company may, at its election, give written notice of such determination to each holder of registrable securities and thereupon shall be relieved of its obligation to register any registrable securities in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith as provided herein). (e) Notice. The Company will give prompt written notice to all holders of Shares of its intention to effect such a registration at least 30 days prior to the anticipated filing date of the registration statement relating to such registration. Such notice will offer the holders of Shares the opportunity to include in such registration statement such registrable securities as each holder of Shares may request in writing within 20 days after the receipt of the Company's notice. 4. Registration Expenses. The Company will pay all reasonable expenses incident to the Company's performance of or compliance with this Agreement, including without limitation all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, and fees and disbursements of counsel for the Company, and all independent certified public accountants, underwriters, excluding any underwriters' discount applicable to the Shares, its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any special annual audit or quarterly review and the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed or on the NASD automated quotation system, and other persons or entities re-tained by the Company (all such expenses being herein called "Registration Expenses"). 5. Indemnification. (a) The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Shareholder and each shareholder, partner, member, director and officer of such Shareholder (within the meaning of the Act) against any and all losses, claims, damages, liabilities, expenses (including reasonable attorneys fees and expenses), or any amounts paid in settlement of any litigation or investigation or proceeding by any governmental body, commenced or threatened ("Claims") to which each such indemnified party may become subject under the Act or otherwise insofar as such Claim arose out of (i) any untrue or alleged untrue statement of material fact contained, on the effective date thereof, in any Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, (ii) 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, (iii) any violations by the Company of any federal, state or common law rule or regulation applicable to the Company and relating to action required of or inaction by the Company in connection with any such registration, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Shareholder expressly for use therein or by such Shareholder's failure to deliver a copy of the Registration Statement or prospectus or any amendments or supplements thereto after the Company has furnished such Shareholder with a sufficient number of copies of the same. In connection with an underwritten offering, the Company will indemnify such underwriters, their officers and directors and each person or entity who controls such underwriters (within the meaning of the Act) at least to the same extent as provided above with respect to the indemnification of the Shareholders. (b) Each Shareholder will furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or prospectus and, to the extent permitted by law, will indemnify the Company, its directors and officers and each person or entity who controls the Company or such underwriter (within the meaning of the Act) against any and all Claims to which each such indemnified party may become subject under the Act insofar as such Claim arose out of (i) the Company's reliance upon any untrue or alleged untrue statement of material fact contained, on the effective date thereof, in any Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, (ii) 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, (iii) any violations by such person or entity of any federal, state or common law rule or regulation applicable to such person or entity and relating to action required of or inaction by such person or entity in connection with any such registration, except insofar as the same are caused by or contained in any information furnished in writing to such person or entity by the Company expressly for use therein only to the extent that such untrue statement or omission was made in reliance upon written information furnished by such Shareholder specifically for use in the preparation of such Registration Statement or prospectus; provided that the obligation to indemnify will be individual to each Shareholder and will be limited to the net amount of proceeds received by or credited to the account of each such Shareholder from the sale of Shares pursuant to such Registration Statement. Notwithstanding the foregoing, the obligation to indemnify will apply only to the extent that such untrue statement or omission was made in reliance upon written information furnished by such Shareholder specifically for use in the preparation of such Registration Statement or prospectus. (c) Any person or entity entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (but the failure to provide such notice shall not release the indemnifying party of its obligation under paragraph (b), unless the indemnifying party has been prejudiced by such failure to provide such notice) and (ii) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. (d) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and will survive the transfer of securities. The Company also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in the event the Company's indemnification is unavailable for any reason. (e) If the indemnification provided for in this paragraph 5 is for any reason, other than pursuant to the terms thereof, held to be unavailable to an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company and the Shareholders in connection with the statements or omission which resulted in such losses, claims, damages, liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact relates to information supplied by the Company or the Shareholder and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Shareholder agree that it would not be just and equitable if contribution pursuant to this subparagraph (e) were determined by any method of allocation which does not take account of the equitable considerations referred to above in this subparagraph (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subparagraph (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Act shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 6. Rule 144. The Company shall take such action as any Shareholder may reasonably request, all to the extent required from time to time to enable such Shareholder to sell such Shares without registration under the Act pursuant to and in accordance with (x) Rule 144 under the Act, as such Rule may be amended from time to time, or (y) any similar rule or regulation hereafter adopted by the Commission. Upon the request of any Shareholder, the Company will deliver to such holder a written statement as to whether it has complied with such requirements. 7. Miscellaneous. (a) Remedies. Any person or entity having rights under any provision of this Agreement will be entitled to enforce such rights specifically to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any bond or other security) for specific performance and for other injunctive relief in order to enforce or prevent violation of the provisions of this Agreement. (b) Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended or waived only upon the prior written consent of the Company and all Shareholders. (c) Successors and Assigns; Transfer of Registration Rights. All covenants and agreements in this Agreement by or on behalf of any of the parties hereto will bind and inure to the benefit of the respective successors and assigns of the parties hereto whether so expressed or not. (d) Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement. (e) Counterparts. This Agreement may be executed simultaneously in two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together will constitute one and the same Agreement. (f) Descriptive Headings. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement. (g) Governing Law. The law of the State of Delaware will govern all issues concerning the relative rights of the Company and its stockholders and all other questions concerning the construction, validity and interpretation of this Agreement and the exhibits and schedules hereto, without regard to its choice of law principles. (h) Notices.
