and (xiii)to such counsel's knowledge, except as set forth in the Final Memorandum, no holders of Common Stock or other securities of the Company have registration rights with respect to securities of the Company and all such rights, because of the filing of the registration statement required to be filed pursuant to the Registration Agreement have, with respect thereto, been waived. -12- 13 Such counsel shall also state that, in the course of preparation by the Company of the Final Memorandum, such counsel has participated in conferences with officers and other representatives of the Company, representatives of the Initial Purchasers and representatives of counsel for the Initial Purchasers, at which conferences the contents of the Final Memorandum and related matters were reviewed and discussed and, although such counsel has not independently verified, the accuracy, completeness or fairness of the statements contained in the Final Memorandum (other than as set forth in clauses (xi) and (xii) above), no facts have come to the attention of such counsel that would lead such counsel to believe that the Final Memorandum (other than the financial statements including supporting schedules and other financial and statistical information contained therein, as to which such counsel need not express any comment), as of its date or on the Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction other than the State of California or the United States or the Delaware General Corporation Law to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Initial Purchasers and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. (b) The Initial Purchasers shall have received from Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel for the Initial Purchasers, such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Securities, the Indenture, the Final Memorandum (together with any amendment or supplement thereof or thereto) and other related matters as the Initial Purchasers may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. (c) The Company shall have furnished to the Initial Purchasers a certificate of the Company, signed by the Chairman of the Board or the President and the principal financial or accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Final Memorandum, any amendment or supplement to the Final Memorandum and this Agreement and that: (i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied pursuant to this agreement at or prior to the Closing Date; and (ii) since the date of the most recent financial statements incorporated by reference in the Final Memorandum (exclusive of any amendment or supplement thereof or thereto), there has been no material adverse change in the condition -13- 14 (financial or other), earnings, business or properties of the Company, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Final Memorandum (exclusive of any amendment or supplement thereof or thereto). (d) At the Closing Date, Coopers & Lybrand L.L.P. shall have furnished to the Initial Purchasers a letter or letters, dated as of the Closing Date, in form and substance satisfactory to the Initial Purchasers, confirming that they are independent accountants within the meaning of the Exchange Act and the applicable published rules and regulations thereunder and stating in effect that: Coopers & Lybrand L.L.P. addressed to the Initial Purchasers, dated the Closing Date, confirming that they are independent certified public accountants with respect to the Company, within the meaning of the Act and the Rules and Regulations and based upon the procedures described in their letter delivered to you concurrently with the execution of this Agreement (herein called the "Original Letter"), but carried out to a date not more than five business days prior to the Closing Date, (i) confirming, to the extent true, that the statements and conclusions set forth in the Original Letter are accurate as of the Closing Date; and (ii) setting forth any revisions and additions to the statements and conclusions set forth in the Original Letter which are necessary to reflect any changes in the facts described in the Original Letter since the date of such letter, or to reflect the availability of more recent financial statements, data or information. The letter shall not disclose any change or any development involving a prospective change, in or affecting the business or properties of the Company which, in your sole judgment, makes it impracticable or inadvisable to proceed with the sale of the Securities as contemplated by the Final Memorandum. The Original Letter from Coopers & Lybrand L.L.P. shall be addressed to or for the use of the Initial Purchasers in form and substance satisfactory to the Initial Purchasers and shall (i) represent, to the extent true, that they are independent certified public accountants with respect to the Company within the meaning of the Act and the applicable published Rules and Regulations, (ii) set forth their opinion with respect to their examination of the consolidated balance sheet of the Company as of March 31, 1996 and related consolidated statements of operations, shareholders' equity, and cash flows for the twelve (12) months ended March 31, 1996, (iii) state that Coopers & Lybrand L.L.P. has performed the procedures set out in the Statement on Auditing Standards No. 71 ("SAS 71") for a review of interim financial information and providing the report of Coopers & Lybrand L.L.P. as described in SAS 71 on the financial statements for each of the quarters in the two quarter period ended September 30, 1996 (the "Quarterly Financial Statements"), (iv) state that in the course of such review, nothing came to their attention that leads them to believe that any material modifications need to be made to any of the Quarterly Financial Statements in order for them to be in compliance with generally accepted accounting principles consistently applied across the periods presented, (v) state that nothing came to their attention that caused them to believe that the pro forma financial statements contained in the Final Memorandum do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X, or that the pro forma adjustments thereto have not been properly applied to the historical amounts in the completion of such statements, and (vi) address other matters agreed upon by Coopers & Lybrand L.L.P. and you. In addition, you shall have received from Coopers & Lybrand L.L.P. a letter addressed to the Company and made available to you for the use of the Initial Purchasers stating that their review of the Company's system of internal accounting controls to the extent they deemed necessary in establishing the scope of their examination -14- 15 of the Company's consolidated financial statements as of March 31, 1996, did not disclose any weaknesses in internal controls that they considered to be material weaknesses. (e) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Final Memorandum (exclusive of any amendment or supplement thereof or thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (d) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the business or properties of the Company the effect of which, in any case referred to in clause (i) or (ii) above, is, in the reasonable judgment of the Initial Purchasers, to make it impractical or inadvisable to market the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereof or thereto). (f) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Company's debt securities by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Securities Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change. (g) The Company shall have furnished to the Initial Purchasers a certificate of the Company, signed on behalf of the Company by the Chairman of the Board and Chief Financial Officer of the Company, to the effect that the signers of such certificate have carefully examined the Final Memorandum, any amendment or supplement to the Final Memorandum and this Agreement and that, and the Initial Purchasers shall be satisfied that: (i) The representations and warranties of the Company in this Agreement are true and correct, as if made on and as of the Execution Time and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Execution Time; (ii) As of the date of this Agreement and at all times subsequent thereto up to the delivery of such certificate, the Final Memorandum did not and does not include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances in which made, not misleading, and, since the date of this Agreement, there has occurred no event necessary to be set forth in an amended or supplemented Final Memorandum in order to make any statements in such Final Memorandum, in light of the circumstances under which made, not misleading, which has not been so set forth; and (iii) Subsequent to the respective dates as of which information is given in each Memorandum, there has not been (A) any material adverse change in the business, properties or assets described or referred to in the Final Memorandum or in the condition (financial or otherwise), earnings, operations or business of the Company or any change which would adversely affect the power or ability of the Company to perform its obligations under this Agreement, the Indenture, the Registration Agreement or the Securities, (B) any change in the capital stock or outstanding indebtedness of the Company which is material to the Company, except for the issuance -15- 16 of the Securities pursuant hereto, or (C) any loss or damage (whether or not insured) to the property of the Company which has been sustained or will have been sustained which has a material adverse effect on the condition (financial or otherwise), earnings, operations, business or business prospects of the Company. (h) The Company shall have furnished to the Initial Purchasers satisfactory evidence that the execution, delivery and performance by the Company of this Agreement, the Indenture and the Registration Agreement, and the issuance of the Securities, will not result in breach of or default under that certain Amended and Restated Revolving Credit Agreement dated as of August 28, 1996 among the Company, the lenders party thereto and The First National Bank of Boston, as administrative agent, as amended through the Closing Date (the "Revolving Credit Agreement"). (i) At the Execution Time, the Company shall have furnished to the Initial Purchasers letters substantially in the form of Exhibit C hereto from the executive officers and directors of the Company, and from Summit Partners, L.P. and Hitachi Metals, Ltd., in which each such person agrees, for a period of ninety (90) days after the last date of original issuance of the Securities to the Initial Purchasers, not to offer to sell, contract to sell or otherwise sell, dispose of, loan, pledge or grant any rights with respect to any shares of Common Stock, any options or warrants to purchase any shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock, now owned or hereafter acquired directly by such person or with respect to which such person has or hereafter acquires the power of disposition, otherwise than (i) as to any individual, during his or her lifetime or upon death, by gift, will or intestacy, to his or her immediate family or to a trust the beneficiaries of which are exclusively such person and/or a member or members of such person's immediate family; provided any donee or transferee thereof agrees in writing to be bound by such agreement, (ii) as a distribution to partners or stockholders of such person, provided that the distributees thereof agree in writing to be bound by the terms of such agreement or (iii) with the prior written consent of Salomon Brothers Inc. (j) Prior to the Closing Date, the Company shall have furnished to the Initial Purchasers such further information, certificates and documents as the Initial Purchasers may reasonably request. If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Initial Purchasers and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be canceled at, or at any time prior to, the Closing Date by the Initial Purchasers. Notice of such cancellation shall be given to the Company in writing or by telephone or telefax confirmed in writing. -16- 17 The documents required to be delivered by this Section 6 shall be delivered at the offices of Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel for the Initial Purchasers, at 650 Page Mill Road, Palo Alto, California 94304 on the Closing Date. 7. Reimbursement of Initial Purchasers' Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof (other than paragraph (b) of Section 6) is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Initial Purchasers, the Company will reimburse the Initial Purchasers upon demand for all reasonable and duly documented out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by it in connection with the proposed purchase and sale of the Securities. 8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each of the Initial Purchasers, the directors, officers, employees and agents of each of the Initial Purchasers and each person who controls any of the Initial Purchasers within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in or incorporated by reference into the Preliminary Memorandum, the Final Memorandum or any information provided by the Company to any holder or prospective purchaser of Securities pursuant to Section 5(h), or in any amendment thereof or supplement thereto, or arise out of or are 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, and agrees to reimburse each such indemnified party, as incurred, for any reasonable legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Initial Purchasers specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. (b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, its officers, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to such Initial Purchaser, but only with reference to written information furnished to the Company by or on behalf of such Initial Purchaser specifically for inclusion in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto. This indemnity agreement will be in addition to any liability which each Initial Purchaser may otherwise have. The Company acknowledges that the statements set forth in the last paragraph of the cover page and under the heading "Plan of Distribution" in the Preliminary Memorandum and the Final Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum. -17- 18 (c) 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 the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there are legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and each Initial Purchaser, severally and not jointly, agrees to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and such Initial Purchaser may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and by such Initial Purchaser from the offering of the Securities; provided, however, that in no case shall such Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial -18- 19 Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers, severally and not jointly, shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of each of the Initial Purchasers in connection with the statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses), and benefits received by each such Initial Purchaser shall be deemed to be equal to the total purchase discounts and commissions, in each case as set forth on the cover page of the Final Memorandum. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or such Initial Purchaser. The Company and each Initial Purchaser, severally and not jointly, agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of such Initial Purchasers shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). 9. Substitution of Initial Purchasers. If any Initial Purchaser or Initial Purchasers shall fail to take up and pay for the number of Firm Securities agreed by such Initial Purchaser or Initial Purchasers to be purchased hereunder upon tender of such Firm Securities in accordance with the terms hereof, and if the aggregate number of Firm Securities that such defaulting Initial Purchaser or Initial Purchasers so agreed but failed to purchase does not exceed 5% of the aggregate principal amount of the Firm Securities, the remaining Initial Purchasers shall be obligated, severally in proportion to their respective commitments hereunder, to take up and pay for the Firm Securities that such defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase. If any Initial Purchaser or Initial Purchasers so defaults and the aggregate number of Firm Securities that such defaulting Initial Purchaser or Initial Purchasers agreed but failed to take up and pay for exceeds 5% of the aggregate principal amount of the Firm Securities, the remaining Initial Purchasers shall have the right, but shall not be obligated, to take up and pay for (in such proportions as may be agreed upon among them) the Firm Securities which the defaulting Initial Purchaser or Initial Purchasers so agreed but failed to purchase. If such remaining Initial Purchasers do not, at the Closing Date, take up and pay for the Firm Securities which the defaulting Initial Purchaser or Initial Purchasers so agreed but failed to purchase, the Closing Date shall be postponed for twenty-four hours (including nonbusiness hours) to allow the remaining Initial Purchasers the privilege of substituting within such twenty-four hour period (including non-business hours) another purchaser or purchasers (which may include any nondefaulting Initial Purchaser) reasonably satisfactory to the Company. If no such purchaser or purchasers shall have been substituted as aforesaid by such postponed Closing Date, the Closing Date may, at the option of the Company, be postponed for a -19- 20 further twenty-four hours, if necessary, to allow the Company the privilege of finding another purchaser or purchasers, reasonably satisfactory to you, to purchase the Firm Securities which the defaulting Initial Purchaser or Initial Purchasers so agreed but failed to purchase. If it shall be arranged for the remaining Initial Purchasers or substituted purchasers to take up the Firm Securities of the defaulting Initial Purchaser or Initial Purchasers as provided in this Section , (i) the Company shall have the right to postpone the time of delivery for a period of not more than seven full business days, in order to effect whatever changes may thereby be made necessary in the Memorandum, or in any other documents or arrangements, and the Company agrees promptly to prepare and deliver any amendments or supplements to the Memorandum or other such documents which may thereby be made necessary, and (ii) the respective number of Firm Securities to be purchased by the remaining Initial Purchasers and substituted purchasers shall be taken as the basis of their obligation to purchase hereunder. If the remaining Initial Purchasers shall not take up and pay for all such Firm Securities so agreed to be purchased by the defaulting Initial Purchaser or Initial Purchasers or substitute another purchaser or purchasers as aforesaid, and the Company shall not find or shall not elect to seek another purchaser or purchasers for such Firm Securities as aforesaid, then this Agreement shall terminate. In the event of any termination of this Agreement pursuant to the preceding paragraph of this Section , the Company shall not be liable to any Initial Purchaser (except as provided in Sections 4(j), 5 and 8 hereof) and no Initial Purchaser (other than an Initial Purchaser who shall have failed, otherwise than for some reason permitted under this Agreement, to purchase the principal amount of Firm Securities agreed by such Initial Purchaser to be purchased hereunder, which Initial Purchaser shall remain liable to the Company and the other Initial Purchasers for damages, if any, resulting from such default) shall be liable to the Company (except to the extent provided in Sections 5 and 8 hereof). The term "Initial Purchaser" in this Agreement shall include any person substituted for a Initial Purchaser under this Section . 10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Initial Purchasers, by notice given to the Company prior to delivery of and payment for the Securities, if prior to such time (i) trading in the Company's Common Stock shall have been suspended by the Commission or the National Association of Securities Dealers Automated Quotation National Market, (ii) trading in securities generally on the New York Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on either of such Exchange or Market, (iii) a banking moratorium shall have been declared either by Federal, California or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the reasonable judgment of the Initial Purchasers, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereof or thereto). 11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of -20- 21 the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Company or any of the officers, directors or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. Notices.
