Section 4. Covenants of the Company. The Company further covenants and agrees with the Underwriter as follows: (a) Registration Statement Matters. The Company agrees to make no further amendment or supplement prior to the Closing Date to the Registration Statement or any amendment or supplement to 10 the Prospectus Supplement, which shall be reasonably disapproved by you in good faith promptly after reasonable notice thereof. If necessary, the Company shall file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) under the Act prior to the time confirmations are sent or given, as specified by Rule 462(b)(2) under the Act, and shall pay the applicable fees in accordance with Rule 111 under the Securities Act. The Company agrees to advise you promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Prospectus Supplement or any amended Prospectus Supplement has been filed and to furnish you with copies thereof; to 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), 15 or 15(d) of the Exchange Act subsequent to the date of the Prospectus Supplement and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Shares; to advise you, promptly after it receives notices thereof; (i) of any request by the Commission to amend the Registration Statement or to amend or supplement to the Prospectus Supplement or for additional information; and (ii) of the issuance by the Commission, of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or any order directed at any Incorporated Document or any amendment or supplement thereto or any order preventing or suspending the use of the Basic Prospectus or the Prospectus Supplement or any amendment or supplement thereto or any post-effective amendment to the Registration Statement, of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, of the institution or threatening of any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement or Prospectus Supplement or for additional information; and, in the event of the issuance of any stop order or of any order preventing or suspending the use of the Basic Prospectus or Prospectus Supplement or suspending any such qualification, promptly to use its reasonable best efforts to obtain the withdrawal of such order. (b) Blue Sky Compliance. The Company will cooperate with the Underwriter in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions (United States and foreign) as the Underwriter may reasonably request and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent, and provided further that the Company shall not be required to produce any new disclosure document other than the Prospectus Supplement. The Company will, from time to time, prepare and file such statements, reports and other documents as are or may be required to continue such qualifications in effect for so long a period as the Underwriter may reasonably request for distribution of the Shares. (c) Amendments and Supplements to the Prospectus Supplement and Other Securities Act Matters. The Company will comply with the Act and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus Supplement. If during the period in which a prospectus is required by law to be delivered by a Underwriter or a dealer in connection with the distribution of Shares contemplated by the Prospectus Supplement, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriter or counsel for the Underwriter, it becomes necessary to amend or supplement the Prospectus Supplement in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus Supplement is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus Supplement to comply with any law, the Company promptly will prepare and file with the Commission, and furnish at its own expense to the Underwriter and to dealers, an appropriate amendment to the Registration Statement or supplement to the Prospectus Supplement so that the Prospectus 11 Supplement as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus Supplement will comply with such law. (d) Copies of any Amendments and Supplements to the Prospectus Supplement. The Company agrees to furnish the Underwriter, without charge, during the period beginning on the date hereof and ending on the later of the Closing Date or such date, as in the opinion of counsel for the Underwriter, the Prospectus Supplement are no longer required by law to be delivered in connection with sales by the Underwriter or dealer (the "Prospectus Delivery Period"), as many copies of the Prospectus Supplement and any amendments and supplements thereto (including any Incorporated Documents) as the Underwriter may reasonably request. (e) Notice of Subsequent Events. If at any time prior to the 90th day after the date of the Prospectus Supplement, any rumor, publication or event relating to or affecting the Company shall occur as a result of which, in your opinion, the market price of the Common Stock has been or is likely to be materially affected (regardless of whether such rumor, publication or event necessitates a supplement to or amendment of the Prospectus Supplement), the Company will, after written notice from you advising the Company to the effect set forth above and setting forth in reasonable detail the basis for your opinion in respect thereof, forthwith prepare, consult with you concerning the substance of and disseminate a press release or other public statement, reasonably satisfactory to you, responding to or commenting on such rumor, publication or event.

(i) Periodic Reporting Obligations. During the Prospectus Delivery Period, the Company shall duly file, on a timely basis, with the Commission and the Nasdaq National Market all reports and documents required to be filed under the Exchange Act within the time periods required by the Exchange Act. (j) Agreement Not to Offer or Sell Additional Securities. The Company will not without the consent of Robertson Stephens, Inc. offer, sell or contract to sell, or otherwise dispose of or enter into any transaction which is designed to, or could reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company) directly or indirectly, or announce the offering of, any other shares of Common Stock or any securities convertible into, or exchangeable or exercisable for, Common Stock; provided, however, that the Company may: (i) issue and sell the Shares pursuant hereto; (ii) issue and sell shares of Common Stock pursuant to any director or employee stock option plan, stock ownership plan or dividend reinvestment plan of the Company in effect at the date of the Prospectus Supplement and described in the Prospectus Supplement so long as none of those shares may be transferred and the Company shall enter stop transfer instructions with its transfer agent and registrar against the transfer of any such Common 12 Stock; (iii) the Company may issue shares of Common Stock issuable upon the conversion of securities or the exercise of warrants or options outstanding at the date of the Prospectus Supplement and described in the Prospectus Supplement; (iv) the Company may issue shares of Common Stock for acquisitions to persons who agree not to sell, contract or otherwise dispose of or hedge such Common Stock during the remainder of the Lock-up Period (as defined below); and (v) the Company may issue and sell the securities described in the Basic Prospectus pursuant to another supplement to the Basic Prospectus. These restrictions terminate after the close of trading of the Shares on the 90th day after the Closing Date. (k) Future Reports to the Underwriter. During the period of five years hereafter the Company will furnish to the Underwriter: (i) as soon as practicable after the end of each fiscal year, copies of the Annual Report of the Company containing the balance sheet of the Company as of the close of such fiscal year and statements of income, stockholders' equity and cash flows for the year then ended and the opinion thereon of the Company's independent public certified public accountants or chartered accountants; (ii) as soon as practicable after the filing thereof, copies, with all exhibits, if any, of each proxy statement, Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other report filed by the Company with the Commission, the NASD, or any other securities exchange; and (iii) as soon as available, copies of any report or communication of the Company mailed generally to holders of its capital stock.

Section 8. Indemnification and Contribution. (a) Indemnification of the Underwriter. The Company agrees to indemnify and hold harmless the Underwriter, its officers and employees, and each person, if any, who controls the Underwriter within the meaning of the Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which the Underwriter or such controlling person may become subject, under the Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, which consent shall not be unreasonably withheld), insofar as such loss, claim, damage, 16 liability or expense (or actions in respect thereof as contemplated below) arises out of or is based: (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or the omission or alleged omission therefrom of 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; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in the Basic Prospectus or the Prospectus Supplement (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; or (iv) in whole or in part upon any failure of the Company to perform its obligations hereunder or under law; or (v) upon any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials provided by the Company or based upon written information furnished by or on behalf of the Company including, without limitation, slides, videos, films or tape recordings, used in connection with the marketing of the Shares, including without limitation, statements communicated to securities analysts employed by the Underwriter; or (vi) any act or failure to act or any alleged act or failure to act by the Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon any matter covered by clause (i), (ii), (iii), (iv) or (v) above, provided that the Company shall not be liable under this clause (vi) to the extent that a court of competent jurisdiction shall have determined by a final judgment that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by the Underwriter through its bad faith or willful misconduct; and to reimburse the Underwriter and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by Robertson Stephens) as such expenses are reasonably incurred by the Underwriter or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use in the Registration Statement, the Basic Prospectus or the Prospectus Supplement (or any amendment or supplement thereto); and provided, further, that with respect to any preliminary prospectus, the foregoing indemnity agreement shall not inure to the benefit of the Underwriter from whom the person asserting any loss, claim, damage, liability or expense purchased Shares, or any person controlling such Underwriter, if copies of the Prospectus Supplement were timely delivered to the Underwriter pursuant to Section 3 and a copy of the Prospectus Supplement (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of the Underwriter to such person, if required by law so to have been delivered, and if the Prospectus Supplement (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or expense. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have. (b) Indemnification of the Company, its Directors and Officers. The Underwriter agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer or controlling person may become subject, under the Act, the Exchange Act, or other federal, state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as 17 contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus or the Prospectus Supplement (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus or the Prospectus Supplement (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that the Underwriter may otherwise have. (c) Information Provided by the Underwriter. The Company and each person, if any, who controls the Company within the meaning of the Act or the Exchange Act, hereby acknowledges that the only information that the Underwriter has furnished to the Company expressly for use in the Registration Statement, the Basic Prospectus or the Prospectus Supplement (or any amendment or supplement thereto) are the statements set forth under the caption "Underwriting" (excluding the fourth and seventh paragraphs thereunder) in the Prospectus Supplement, and the Underwriter confirms that such statements are correct. (d) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability, which it may have to any indemnified party for contribution to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party's election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless: (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party), representing the indemnified parties who are parties to such action); (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action; or (iii) the indemnifying party has 18 authorized the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. (e) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(d), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if: (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request; and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes: (i) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding; and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (f) Contribution. If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party in such proportion as is appropriate to reflect the relative benefits received by such party on the one hand and the Underwriter on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings 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 or the omission or alleged omission to state a material fact relates to information supplied by the Company or the "control" stockholders on the one hand or the Underwriter on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 8(f) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(f) 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. Notwithstanding the provisions of this subsection (f): (i) the Underwriter shall not be required to contribute any amount in excess of the amount of the Underwriter fees actually received by the Underwriter pursuant to this Agreement; and (ii) 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. 19 (g) Timing of Any Payments of Indemnification. Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred, but in all cases, no later than forty-five (45) days of invoice to the indemnifying party. (h) Survival. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties set forth in this Agreement shall remain operative and in full force and effect, regardless of: (i) any investigation made by or on behalf of the Underwriter or any person controlling the Underwriter, the Company, its directors or officers or any persons controlling the Company; (ii) acceptance of any Shares and payment therefor hereunder; and (iii) any termination of this Agreement. A successor to the Underwriter, or to the Company, its directors or officers or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8. (i) Acknowledgements of Parties.

(ii) Such counsel knows of no material action, suit, claim or proceeding relating to patents, patent rights or licenses, trademarks or trademark rights, copyrights, collaborative research, licenses or royalty arrangements or agreements or trade secrets, know-how or proprietary techniques, including processes and substances, owned by or affecting the business or operations of the Company which are pending or threatened against the Company or any of its officers or directors.
