(xix) Company Counsel has participated in the preparation of the Registration Statement and the Prospectus, including reviews and discussions of the contents thereof, and, in the course of such reviews and discussions, no facts came to its attention that would cause it to have reason to believe that (A) the Registration Statement or any post-effective amendment thereto, on the date it became effective and on the Closing Date or the Option Closing Date, as the case may be, contained any untrue statement of a material fact or omitted any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or that (B) the Prospectus on the Effective Date, on the date it was filed pursuant to Rule 424(b) under the Act and on the Closing Date or Option Closing Date, as the case may be, contained any untrue statement of material fact or omitted any material fact necessary to make the statements therein, in light of the circumstances under which made, not misleading (except, in each case, for the financial statements and related schedules therein and the financial data and calculations therein based on such financial statements and schedules, as to which Company Counsel need not express an opinion). The foregoing opinion may be limited to the laws of the United States, the laws of the State of California and the GCL, and Company Counsel may rely as to certain legal matters on other counsel to the Company provided that in each case, Company Counsel shall state that they believe that they and the Underwriters are justified in relying on such other counsel and shall deliver signed copies of any such opinion to the Representatives and as to questions of fact upon the representations of the Company set forth in this Agreement and upon certificates of officers of the Company and of governmental officials, all of which certificates must be reasonable and satisfactory in form and scope to counsel for the Underwriters provided that in each case, Company Counsel shall deliver signed copies of any such certificate to the Representatives. (g) At the Closing Date and any Option Closing Date: (A) the Registration Statement and any post-effective amendment thereto and the Prospectus and any amendments or supplements thereto shall contain all statements that are required to be stated therein in accordance with the Act and the Regulations and shall conform, in all material respects, to the requirements of the Act and the Regulations, and neither the Registration Statement nor any post-effective amendment thereto nor the Prospectus and any amendments or supplements thereto shall contain any 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, in light of the circumstances under which they were made, not misleading, (B) since the respective dates 23 as of which information is given in the Registration Statement and any post-effective amendment thereto and the Prospectus and any amendments or supplements thereto, except as otherwise stated therein, there shall have been no material adverse change in the properties, condition (financial or otherwise), results of operations, stockholders' equity, business or management of the Company, from that set forth therein, whether or not arising in the ordinary course of business, other than as referred to in the Registration Statement or Prospectus, (C) since the respective dates as of which information is given in the Registration Statement and any post- effective amendment thereto and the Prospectus or any amendment or supplement thereto, there shall have been no transaction, contract or agreement entered into by the Company, other than in the ordinary course of business and as set forth in the Registration Statement or Prospectus that has not been, but would be required to be, set forth in the Registration Statement or Prospectus; (D) no action, suit or proceeding at law or in equity shall be pending or, to the knowledge of the Company, threatened against the Company that would be required to be set forth in Prospectus, other than as set forth therein, and no proceedings shall be pending or, to the knowledge of the Company, threatened against the Company before or by any federal, state or other commission, board or administrative agency wherein an unfavorable decision, ruling or finding would materially adversely affect the properties, condition (financial or otherwise), results of operations, stockholders' equity or business of the Company, other than as set forth in the Prospectus. The Representatives shall have received at the Closing Date and any Option Closing Date certificates of each of the Chief Executive Officer and the Chief Financial Officer of the Company dated as of the date of the Closing Date or Option Closing Date, as the case may be, and addressed to the Representatives, individually and as the Representatives of the several Underwriters, to the effect, that the conditions set forth in this subsection have been satisfied and as to the accuracy and performance, as of the Closing Date or the Option Closing Date, as the case may be, of the agreements, representations and warranties of the Company set forth herein. (h) At the time this Agreement is executed and at the Closing Date and any Option Closing Date, the Representatives shall have received a letter addressed to the Representatives, individually and as the Representatives of the several Underwriters, and in form and substance satisfactory to the Representatives in all respects (including the nonmaterial nature of the changes or decreases, if any, referred to in clause (iii) below) from Ernst & Young LLP dated as of the date of this Agreement, the Closing Date or Option Closing Date, as the case may be: (i) confirming that they are independent public accountants within the meaning of the Act and the Regulations and stating that the section of the Registration Statement under the caption "Experts" is correct insofar as it relates to them; (ii) stating that, in their opinion, the financial statements of the Company audited by them and included in the Registration Statement comply in form in all material respects with the applicable accounting requirements of the Act and the Regulations; (iii) stating that, on the basis of specified procedures, which included a reading of the latest available unaudited interim financial statements of the Company (with an indication of the date of the latest available unaudited interim financial statements), a reading of the minutes of the meetings of the stockholders and the 24 Board of Directors of the Company and audit and compensation committees of such Board, if any, and inquiries to certain officers and other employees of the Company who are responsible for financial and accounting matters and other specified procedures and inquiries, nothing has come to their attention that would cause them to believe that (A) the unaudited financial statements and related schedules of the Company included in the Registration Statement, if any, (I) do not comply in form in all material respects with the applicable accounting requirements of the Act and the Regulations or (II) were not fairly presented in conformity with generally accepted accounting principles on a basis substantially consistent with that of the audited financial statements and related schedules included in the Registration Statement or (B)(I) at a specified date, not more than five business days prior to the date of such letter there was any change in the capital stock or short-term or long-term debt of the Company, or any decrease (increase) in net current assets, total assets or stockholders' equity as compared with the amounts shown in the __________, 1995 balance sheet of the Company included in the Registration Statement, other than as set forth in or contemplated by the Registration Statement and Prospectus, and (II) during the period from __________, 1995 to a specified date not more than five business days prior to the date of such letter, there has been any decrease (increase), as compared with the corresponding period in the preceding year, in revenues, operating income or income before income taxes or in total or per share amounts of net income of the Company or, if there was any such change or decrease (increase), setting forth the amount of such change or decrease (increase); and (iv) stating that they have compared specific dollar amounts, numbers of shares and other information (including pro forma information) pertaining to the Company set forth in the Registration Statement and Prospectus that have been specified by the Representatives prior to the date of this Agreement, to the extent that such amounts, numbers, percentages and information may be derived from the general accounting or other records of the Company with the result obtained from the application of specified readings, inquiries and other appropriate procedures (which procedures do not constitute an audit in accordance with generally accepted auditing standards) set forth in the letter, and found them to be in agreement. (i) The Company shall have executed and delivered a Warrant Agreement in a form satisfactory to the Representatives (the "Warrant Agreement") and here shall have been tendered to the Representatives certificates representing all of the Representatives Warrants described in subsection (r) of Section 5, to be purchased by the Representatives on the Closing Date. (j) At the Closing Date and any Option Closing Date, the Representatives shall have been furnished such additional documents and certificates as they shall reasonably request. (k) No action shall have been taken by the NASD the effect of which is to make it improper, at any time prior to the Closing Date or any Option Closing Date, for members of the NASD to execute transactions as principal or as agent in the Shares or to trade or deal in the Shares, and no proceedings for the purpose of taking such action shall have been 25 instituted or shall be pending or, to the Company's or the Representatives' knowledge, shall be contemplated by the NASD. If any conditions to the Underwriters' obligations hereunder to be fulfilled prior to or at the Closing Date or any Option Closing Date, as the case may be, shall not have been fulfilled, the Representatives may on behalf of the several Underwriters terminate this Agreement or, if they so elect, waive any such conditions which have not been fulfilled or extend the time for their fulfillment. 8. INDEMNIFICATION. (a) The Company shall indemnify and hold harmless each Underwriter, and each person, if any, who controls each Underwriter within the meaning of the Act or the Exchange Act, against any and all loss, liability, claim, damage and expense whatsoever, including, but not limited to, any and all expense whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever or in connection with any investigation or inquiry of, or action or proceeding that may be brought against, the respective indemnified parties, arising out of or based upon any untrue statements or alleged untrue statements of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any application or other document (in this Section 8 collectively called "application") executed by the Company and based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify all or any part of the Shares under the securities laws thereof or filed with the SEC or the NASD, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the foregoing indemnity (i) shall not apply in respect of any statement or omission made in reliance upon and in conformity with written information furnished to the Company or any Underwriter through the Representatives expressly for use in any Preliminary Prospectus, the Registration Statement or Prospectus, or any amendment or supplement thereof, or in any application or in any communication to the SEC, as the case may be, and (ii) with respect to any Preliminary Prospectus, shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages, liabilities or expenses purchase the Shares that are the subject thereof (or to the benefit of any person controlling such Underwriter) if at or prior to the written confirmation of the sale of such Shares a copy of an amended Preliminary Prospectus or the Prospectus (or the Prospectus as amended or supplemented) was not sent or delivered to such person and the untrue statement or omission of a material fact contained in such Preliminary Prospectus was corrected in the amended Preliminary Prospectus or Prospectus (or the Prospectus as amended or supplemented). It is understood that the statements appearing in any Preliminary Prospectus, the Prospectus or the Registration Statement (A) on the inside front cover page with respect to stabilization, (B) in the table in the section entitled "Underwriting," and the second paragraph following such table with respect to the amount of the dealers' concession and allowance and reallowance discount and (C) in the section entitled "Legal Matters" with respect to the identity of counsel for the Underwriters constitute the only information furnished in writing by or on behalf of any Underwriter for inclusion in any Preliminary Prospectus, the Prospectus or the Registration Statement. This indemnity agreement will be in addition to any liability the Company may otherwise have. 26 (b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement and each other person, if any, who controls the Company within the meaning of the Act or the Exchange Act to the same extent as the foregoing indemnities from the Company to the several Underwriters, but only with respect to any loss, liability, claim, damage or expense resulting from (i) statements or omissions, or alleged statements or omissions, if any, made in any Preliminary Prospectus, Registration Statement or Prospectus or any amendment or supplement thereof or any application in reliance upon, and in conformity with written information furnished to the Company by any Underwriter through the Representatives with respect to any Underwriter by or on behalf of such Underwriter expressly for use in any Preliminary Prospectus, the Registration Statement or Prospectus or any amendment or supplement thereof or any application, as the case may be, (ii) the failure of any Underwriter at or prior to the written confirmation of the sale of Shares to send or deliver a copy of an amended Preliminary Prospectus or the Prospectus (or the Prospectus as amended or supplemented) to the person asserting any such losses, claims, damages, liabilities or expenses who purchased the Shares that are the subject thereof and the untrue statement or omission of a material fact contained in such Preliminary Prospectus was corrected in the amended Preliminary Prospectus or Prospectus (or the Prospectus as amended or supplemented) or (iii) the failure to qualify the offering or sale of the Shares by the several Underwriters under the state securities or Blue Sky laws or any jurisdiction referred to in Section 5(f) hereof which failure to qualify is the result of the failure to file the pertinent materials in any such jurisdiction. This indemnity agreement will be in addition to any liability such Underwriter may otherwise have. (c) If any action, inquiry, investigation or proceeding is brought against any person in respect of which indemnity may be sought pursuant to any of the two preceding paragraphs, such person (hereinafter called the "indemnified party") shall, promptly after formal notification of, or receipt of service of process for, such action, inquiry, investigation or proceeding, notify in writing the party or parties against whom indemnification is to be sought (hereinafter called the "indemnifying party") of the institution of such action, inquiry, investigation or proceeding and the indemnifying party, upon the request of the indemnified party, shall assume the defense of such action, inquiry, investigation or proceeding, including the employment of counsel (reasonably satisfactory to such indemnified party) and payment of expenses. No indemnification provided for in this Section 8 shall be available to any indemnified party who shall fail to give such notice if the indemnifying party does not have knowledge of such action, inquiry, investigation or proceeding and shall have been materially prejudiced by the failure to give such notice, but the omission so to notify the indemnifying party shall not relieve the indemnifying party otherwise than under this Section 8. Such indemnified party or controlling person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action or the indemnifying party shall not have employed counsel to have charge of the defense of such action, inquiry, investigation or proceeding or such indemnified party or parties shall have been advised by counsel that there is a conflict of interest that would prevent counsel to the indemnifying party from representing both parties, in any of which events the reasonable fees and expenses of such counsel shall be borne by the indemnifying party. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings 27 in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel (in addition to one local counsel in each jurisdiction in which any proceeding may be brought) for all indemnified parties. In the case of any such separate counsel for the Underwriters, such firm shall be designated in writing by the Representative. Expenses covered by the indemnification in this subsection (c) of this Section 8 shall be paid by the indemnifying party as they are incurred by the indemnified party. Anything in this subsection to the contrary notwithstanding, the indemnifying party shall not be liable for any settlement of any such claim effected without its written consent. The indemnifying party shall promptly notify the indemnified party of the commencement of any litigation, inquiry, investigation or proceeding against the indemnifying party or any of its officers or directors in connection with the issue and sale of any of the Shares or in connection with such Preliminary Prospectus, Registration Statement or Prospectus or any amendment thereto or supplement thereof or any such application. (d) If the indemnification provided for in this Section 8 is unavailable to or is insufficient to hold harmless an indemnified party under subsections (a) or (b) of this Section 8 in respect of any losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to therein except either by reason of the provisions set forth in subsections (a) or (b) or the failure to give notice as required in subsection (c) (provided that the indemnifying party does not have knowledge of the action, inquiry, investigation or proceeding and has been materially prejudiced by the failure to give such notice), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters 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 the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, liabilities, claims or reasonable expenses (or actions, inquiries, investigations or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative faults 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 on the one hand or the Underwriters on the other hand and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this section (d) of this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any method or allocation that does not take account of the equitable considerations referred to 28 above in this subsection (d) of this Section 8. The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or reasonable expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to above in this subsection (d) of this Section 8 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 (d) of this Section 8, (i) the provisions of the Agreement Among Underwriters shall govern contribution among Underwriters, (ii) no Underwriter (except as provided in the Agreement Among Underwriters) shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter and (iii) 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. The Underwriters' obligation in this subsection (d) of this Section 8 to contribute are several in proportion to their respective underwriting obligations and not joint. 9. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. Except as the context otherwise requires, all representations, warranties and agreements contained in this Agreement shall be deemed to be representations, warranties and agreements at the Closing Date and any Option Closing Date; and such representations, warranties and agreements of the Underwriters and the Company, including without limitation the indemnity and contribution agreements contained in Section 8 hereof and the agreements contained in Sections 6, 9, 10 and 13 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person, and shall survive delivery of the Shares and termination of this Agreement, whether before or after the Closing Date or any Option Closing Date. 10. EFFECTIVE DATE OF THIS AGREEMENT AND TERMINATION THEREOF. (a) This Agreement shall become effective immediately as to Sections 6, 8, 9, 10 and 13 and, as to all other provisions, (i) if at the time of execution and delivery of this Agreement the Registration Statement has not become effective, at 11:00 A.M., Philadelphia time, on the first business day following the Effective Date, or (ii) if at the time of execution and delivery of this Agreement the Registration Statement has been declared effective, at 11:00 A.M., Philadelphia time, on the date of execution of this Agreement; but this Agreement shall nevertheless become effective at such earlier time after the Registration Statement becomes effective as the Representatives may determine by notice to the Company or by release of any of the Shares for sale to the public. For the purposes of this Section 10, the Shares shall be deemed to have been so released upon the release for publication of any newspaper advertisement relating to the Shares or upon the release by the Representatives of telegrams (i) advising the Underwriters that the shares are released for public offering or (ii) offering the Shares for sale to securities dealers, whichever may occur first. The Representatives may prevent the provisions of this Agreement (other than those contained in Sections 6, 8, 9, 10 and 13) hereof from becoming effective without liability of any party to any other party, except as noted below, by giving the notice indicated in subsection (c) of this Section 10 before the time the other provisions of this Agreement become effective. (b) The Representatives shall have the right to terminate this Agreement at any time prior to the Closing Date as provided in Sections 7 and 11 hereof or if any of the 29 following have occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the condition, financial or otherwise, of the Company, or the earnings, business affairs, management or business prospects of the Company, whether or not arising in the ordinary course of business; (ii) any outbreak of hostilities or other national or international calamity or crisis or change in economic, political or financial market conditions if such outbreak, calamity, crisis or change would, in the Representatives' reasonable judgment, have a material adverse effect on the Company, the financial markets of the United States or the offering or delivery of the Shares; (iii) suspension of trading generally in securities on the New York Stock Exchange, the AMEX or the over-the- counter market or limitation on prices (other than limitations on hours or numbers of days of trading) for securities or the promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in the Representatives' reasonable opinion materially and adversely affects trading on either such Exchange or the over-the-counter market; (iv) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in the Representatives' reasonable opinion materially and adversely affects or will materially and adversely affect the business or operations of the Company; (v) declaration of a banking moratorium by either federal or state authorities; (vi) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs which in the Representatives' reasonable opinion has a material adverse effect on the securities markets in the United States; (vii) declaration of a moratorium in foreign exchange trading by major international banks or other institutions or (viii) trading in any securities of the Company shall have been suspended or halted by the NASD or the SEC. (c) If the Representatives elect to prevent this Agreement from becoming effective or to terminate this Agreement as provided in this Section 10, the Representatives shall notify the Company thereof promptly by telephone, telex, telegraph or facsimile, confirmed by letter. 11. DEFAULT BY AN UNDERWRITER. (a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Offered Shares or Optional Shares hereunder, and if the Offered Shares or Optional Shares with respect to which such default relates do not exceed the aggregate of 10 percent of the number of Offered Shares or Optional Shares, as the case may be, that all Underwriters have agreed to purchase hereunder, then such Offered Shares or Optional Shares to which the default relates shall be purchased severally by the non- defaulting Underwriters in proportion to their respective commitments hereunder. (b) If such default relates to more than 10 percent of the Offered Shares or Optional Shares, as the case may be, the Representatives may in its discretion arrange for another party or parties (including a non- defaulting Underwriter) to purchase such Offered Shares or Optional Shares to which such default relates, on the terms contained herein. In the event that the Representatives do not arrange for the purchase of the offered Shares or Optional Shares to which a default relates as provided in this Section 11, this Agreement may be terminated by the Representatives or by the Company without liability on the part of the 30 several Underwriters (except as provided in Section 8 hereof) or the Company (except as provided in Sections 6 and 8 hereof), but nothing herein shall relieve a defaulting Underwriter of its liability, if any, to the other several Underwriters and to the Company for damages occasioned by its default hereunder. (c) If the Offered Shares or Optional Shares to which the default relates are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, the Representatives or the Company shall have the right to postpone the Closing Date or any Option Closing Date, as the case may be, for a reasonable period but not in any event exceeding seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment to the Registration Statement or supplement to the Prospectus which in the opinion of counsel for the Underwriters may thereby be made necessary. The terms "Underwriters" and "Underwriter" as used in this Agreement shall include any party substituted under this Section 11 with like effects as if it had originally been a party to this Agreement with respect to such Offered Shares or Optional Shares. 12. INFORMATION FURNISHED BY UNDERWRITERS. The statements appearing in any Preliminary Prospectus, the Prospectus or the Registration Statement (a) on the inside front cover page with respect to stabilization, (b) in the table in the section entitled "Underwriting," and the second paragraph following such table with respect to the amount of the dealers' concession and allowance and reallowance discount and (c) in the section entitled "Legal Matters" with respect to the identity of counsel for the Underwriters constitute the only information furnished in writing by or on behalf of any Underwriter for inclusion in any Preliminary Prospectus, the Prospectus or the Registration Statement referred to in subsection (b) of Section 1 hereof and subsections (a) and (b) of Section 8 hereof. 13.
