The Company will file the Final Prospectus with the Commission within the time periods specified by Rule 424(b) and will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Final Prospectus and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Shares; and the Company will furnish copies of the Final Prospectus to the Underwriters in New York City prior to 10:00 A.M., New York City time, to the extent possible on the business day next succeeding the date of this Agreement, and in any event on the second business day next succeeding the date of this Agreement, in such quantities as the Representative may reasonably request. 13 (b) FILING OF THE RULE 462 REGISTRATION STATEMENT. The Company will prepare and file with the Commission the Rule 462 Registration Statement, if necessary, in a form approved by the Representative (which approval shall not be unreasonably withheld or delayed). (c) DELIVERY OF COPIES. The Company will deliver, without charge, (i) to the Representative, a signed copy of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith and documents incorporated by reference therein, and (ii) to each Underwriter (A) a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits) and (B) during the Prospectus Delivery Period, as many copies of the Final Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) as the Representative may reasonably request. As used herein, the term "PROSPECTUS DELIVERY PERIOD" means such period of time after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters a prospectus relating to the Shares is required by law to be delivered in connection with sales of the Shares by any Underwriter or dealer. (d) AMENDMENTS OR SUPPLEMENTS. Before filing any amendment or supplement to the Registration Statement or the Final Prospectus, the Company will furnish to the Representative and counsel for the Underwriters a copy of the proposed amendment or supplement for review and will not file any such proposed amendment or supplement to which the Representative reasonably objects. (e) NOTICE TO THE REPRESENTATIVE. The Company will advise the Representative promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective; (ii) when any amendment or supplement to the Final Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Final Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Final Prospectus or the initiation or threatening of any proceeding for that purpose; (v) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing when the Final Prospectus is delivered to a purchaser, not misleading; and (vi) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Final Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will use reasonable best efforts to obtain as soon as possible the withdrawal thereof. 14 (f) ONGOING COMPLIANCE. If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Final Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Final Prospectus to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (d) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representative may designate, such amendments or supplements to the Final Prospectus as may be necessary so that the statements in the Final Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Final Prospectus is delivered to a purchaser, be misleading or so that the Final Prospectus will comply with law. (g) BLUE SKY COMPLIANCE. The Company will qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representative shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Shares; provided that the Company shall not be required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) file any general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject. (h) EARNING STATEMENT. The Company will make generally available to its security holders and the Representative as soon as practicable an earning statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning on the first day of the first full fiscal quarter after the date of this Agreement. (i) CLEAR MARKET. For a period of 90 days after the date of this Agreement, the Company will not (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Representative, other than the issuance of (i) the Shares to be sold hereunder (including the Shares to be sold by Tekelec), (ii) options to purchase shares of Common Stock granted pursuant to stock option plans as in effect on the date of this Agreement, (iii) shares of Common Stock upon the exercise of options granted under, or shares of Common Stock issued pursuant to, stock option and stock purchase plans, as in effect on the date of this Agreement and (iv) shares of Common Stock issued in connection with acquisitions by the Company PROVIDED that each recipient of such shares executes a lock-up agreement with the Representative in form and substance substantially similar to the lock-up agreement attached as Exhibit C hereto. 15 (j) USE OF PROCEEDS. The Company will apply the net proceeds from the sale of the Shares as described in the Final Prospectus under the heading "Use of Proceeds." (k) NO STABILIZATION. The Company will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Shares. (l) LISTING OF SHARES. The Company will use its reasonable best efforts to file a Notice of Listing of Additional Shares with respect to the Shares on the Nasdaq National Market ("NASDAQ"). (m) REPORTS. So long as the Shares are outstanding, the Company will furnish to the Representative, as soon as they are available, copies of all reports or other communications (financial or other) furnished to holders of the Shares and copies of any reports and financial statements furnished to or filed with the Commission or any national securities exchange or automatic quotation system. 6. FURTHER AGREEMENTS OF THE SELLING STOCKHOLDERS. Each of the Selling Stockholders covenants and agrees with each Underwriter that: (a) TAX FORM. It will deliver to the Representative prior to or at the Closing Date a properly completed and executed United States Treasury Department Form W-9 (or other applicable form or statement specified by the Treasury Department regulations in lieu thereof) in order to facilitate the Underwriters' documentation of their compliance with the reporting and withholding provisions of the Tax Equity and Fiscal Responsibility Act of 1982 with respect to the transactions herein contemplated. 7.

Subsequent to the execution and delivery of this Agreement, no event or condition of a type described in Section 3(e) hereof shall have occurred or shall exist, which event or condition is not described in the Final Prospectus (excluding any amendment or supplement thereto) and the effect of which in the judgment of the Representative makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement and the Final Prospectus. (d) OFFICER'S CERTIFICATE. The Representative shall have received on and as of the Closing Date or the Additional Closing Date, as the case may be, a certificate of (i) the chief executive officer and chief financial officer of the Company (A) confirming that such officers have carefully reviewed the Registration Statement and the Final Prospectus and, to the knowledge of such officers after due inquiry, the representation of the Company set forth in Section 3(b) hereof is true and correct, (B) confirming that the other representations and warranties of the Company in this Agreement are, to the knowledge of such officers after due inquiry, true and correct and that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to such Closing Date and (C) to the effect set forth in paragraphs (a) and (c) of this Section 7 and (ii) of each Selling Stockholder, in form and substance reasonably satisfactory to the Representative, (A) confirming that the representations of such Selling Stockholder set forth in Sections 4(a)(v) and 4(a)(vi) and, if applicable, Section 4(b)(i) hereof are true and correct and (B) confirming that the other representations and warranties of such Selling Stockholder in this agreement are true and correct and that the such Selling Stockholder has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to such Closing Date.

(i) NO LEGAL IMPEDIMENT TO ISSUANCE.

INDEMNIFICATION AND CONTRIBUTION. (a) INDEMNIFICATION OF THE UNDERWRITERS BY THE COMPANY. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Final Prospectus (or any amendment or supplement thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below; provided, that with respect to any such untrue statement or alleged untrue statement in or omission or alleged omission from any Preliminary Prospectus, the indemnity agreement contained in this paragraph (a) shall not inure to the benefit of any Underwriter (or any of its affiliates, directors and officers and controlling persons) to the extent that any such loss, claim, damage or liability of or with respect to such Underwriter results from the fact that both (i) to the extent required by applicable law, a copy of the Final Prospectus was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person and (ii) the untrue statement in or omission from such Preliminary Prospectus was cured in the Final Prospectus unless, in either case, such failure to deliver the Final Prospectus was a result of non-compliance by the Company with the provisions of paragraphs (a), (c), (e) or (f) of Section 5 hereof. (b) INDEMNIFICATION OF THE UNDERWRITERS BY THE SELLING STOCKHOLDERS. Each of the Selling Stockholders severally in proportion to the number of Shares to be sold by such Selling Stockholder hereunder and not jointly, agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material 19 fact contained in the Registration Statement, any Preliminary Prospectus or the Final Prospectus (or any amendment or supplement thereto), or caused by any omission or alleged omission to state therein 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, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below; PROVIDED that (i) the liability of each Selling Stockholder under this paragraph (b) shall be limited to an amount equal to the net proceeds (after deducting all underwriting discounts and commissions paid by such Selling Stockholder but before deducting expenses) received by such Selling Stockholder from the sale of the Shares and (ii) in the case of Tekelec, a California corporation ("TEKELEC"), the indemnity provided for in this paragraph (b) shall apply only to the extent that any such losses, claims, damages or liabilities arise out of, or are based upon, any such untrue statement or alleged untrue statement or any such omission or alleged omission made in reliance upon and in conformity with information relating to Tekelec furnished to the Company in writing by Tekelec expressly for use therein; provided, that with respect to any such untrue statement or alleged untrue statement in or omission or alleged omission from any Preliminary Prospectus, the indemnity agreement contained in this paragraph (a) shall not inure to the benefit of any Underwriter (or any of its affiliates, directors and officers and controlling persons) to the extent that any such loss, claim, damage or liability of or with respect to such Underwriter results from the fact that both (i) to the extent required by applicable law, a copy of the Final Prospectus was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person and (ii) the untrue statement in or omission from such Preliminary Prospectus was cured in the Final Prospectus unless, in either case, such failure to deliver the Final Prospectus was a result of non-compliance by the Company with the provisions of paragraphs (a), (c), (e) or (f) of Section 5 hereof. (c) INDEMNIFICATION OF THE COMPANY AND THE SELLING STOCKHOLDERS. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of the Selling Stockholders, its affiliates, directors and officers, if any, and each person, if any, who controls such Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, any Preliminary Prospectus and the Final Prospectus (or any amendment or supplement thereto), it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following 20 information in the Final Prospectus furnished on behalf of each Underwriter: the information contained in the fifth, ninth, tenth and eleventh paragraphs under the caption "Underwriting". (d) NOTICE AND PROCEDURES. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 8, such person (the "INDEMNIFIED PERSON") shall promptly notify the person against whom such indemnification may be sought (the "INDEMNIFYING PERSON") in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 8 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 8. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 8 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by J.P. Morgan Securities Inc., any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Stockholders shall be designated in writing by the Selling Stockholders. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) 21 includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person. (e) CONTRIBUTION. If the indemnification provided for in paragraphs (a), (b) and (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (after deducting all underwriting discounts or commissions but before deducting expenses) received by the Company and the Selling Stockholders from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Final Prospectus, bear to the aggregate offering price of the Shares. The relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other 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 Company and the Selling Stockholders or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. (f) LIMITATION ON LIABILITY. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (e) above were determined by pro rata allocation (even if the Selling Stockholders or the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 8, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation 22 (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. The Underwriters' obligations to contribute pursuant to this Section 8 are several in proportion to their respective purchase obligations hereunder and not joint. The Selling Stockholders' obligations to contribute pursuant to this Section 8 are several and not joint. (g) NON-EXCLUSIVE REMEDIES. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity or by agreement. Without limiting the generality of the foregoing and in connection with the Registration Statement, any Preliminary Prospectus, the Final Prospectus (or any amendment or supplement thereto) and the transactions contemplated by this Agreement, nothing in this Agreement shall terminate, modify or otherwise affect the indemnification and hold harmless obligations of the Company and Tekelec pursuant to the Registration Rights Agreement dated as of July 15, 2002, between the Company and Tekelec, including without limitation pursuant to Section 3.5 thereof, as supplemented by that certain letter agreement dated March 18, 2004 between the Company and Tekelec (as so supplemented, the "REGISTRATION RIGHTS AGREEMENT"). 9. TERMINATION. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company and the Selling Stockholders, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date, (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement and the Final Prospectus. 10. DEFAULTING UNDERWRITER. (a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company and the Selling Stockholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company and the Selling Stockholders may postpone the Closing Date or 23 the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Selling Stockholders or counsel for the Underwriters may be necessary in the Registration Statement or the Final Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement or the Final Prospectus that effects any such changes. As used in this Agreement, the term "UNDERWRITER" includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Shares that a defaulting Underwriter agreed but failed to purchase. (b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters (or the Company and the Selling Stockholders as provided in (a) above), the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company and the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter's pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made. (c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters (or the Company and the Selling Stockholders as provided in (a) above), the aggregate number of Underwritten Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company and the Selling Stockholders shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Option Shares on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company and the Selling Stockholders, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 8 hereof shall not terminate and shall remain in effect.
