No consent, approval, authorization or order of, or filing with, any federal or California court or governmental agency or body is required for the compliance by the Company with the provisions of this Agreement, except such as have been obtained or as may be required under state securities laws in connection with the purchase and distribution of such Shares by the Underwriter; (x) the statements in the Prospectus under the captions "Business -- Government Regulation" and "Description of Capital Stock," in each case insofar as such statements constitute summaries of the legal matters, documents or proceedings referred to therein, are accurate in all material respects; (xi) to the best of such counsel's knowledge, there are no contracts or other documents, or legal or governmental proceedings to which the Company or any of its subsidiaries is party, that are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement that are not described and filed as required; (xii) the Company is not and, after giving effect to the offering and sale of the Shares and the application of the proceeds thereof as described in the Prospectus, will not be an "investment company" as such term is defined in the Investment Company Act of 1940, as amended; (xiii) each document filed pursuant to the Exchange Act and incorporated by reference in the Registration Statement and the Prospectus (except for financial statements, schedules and other financial data included or incorporated by reference in, or omitted from, the Registration Statement or the Prospectus as to which such counsel need not express any opinion) complied when so filed as to form in all material respects with the requirements for such documents under the Exchange Act and the applicable rules and regulations of the Commission thereunder. The Registration Statement and Prospectus (except for financial statements and schedules and other financial data included or incorporated by reference in, or omitted from, the Registration Statement or the Prospectus as to which such counsel need not express any opinion) comply as to form in all material respects with the requirements for registration statements on Form S-3 under the Securities Act and the applicable rules and regulations of the Commission thereunder. In passing upon the compliance as to form of each such document filed pursuant to the Exchange Act and the Registration Statement and the Prospectus, such counsel may assume that the statements made and incorporated by reference therein are correct and complete; 13 14 (xiv) Schedule III attached thereto includes all licenses, authorizations, and permits required under the Communications Act or the FCC Rules, which are necessary for the Company and its domestic subsidiaries to conduct their business as such counsel has been advised they are now conducted and as proposed to be conducted immediately following the Closing Date (the "FCC LICENSES"). Schedule III attached thereto accurately sets forth each such license, the name of the licensee, the call letters (if applicable), the class of service, geographic scope and the expiration date for each of the FCC Licenses, each of which is in full force and effect; (xv) except as described in the Prospectus, other than rulemaking proceedings or similar proceedings generally affecting the commercial mobile radio services industry, there is no proceeding before the FCC that is pending or, to the best of such counsel's knowledge, threatened against the Company, its domestic subsidiaries or any of their officers, directors or shareholders, including any FCC complaint, investigation, notice of apparent liability, order of forfeiture, proceeding pursuant to an exercise of pre-emptive authority under 47 U.S.C. Section 252, or other administrative action or proceeding, regarding the business of the Company and its domestic subsidiaries (i) that is likely to result in a forfeiture or termination, revocation, adverse modification, non-renewal, short-term renewal, or other material impairment of any of the FCC Licenses, or (ii) that reasonably could be expected to materially and adversely affect the operations or condition, financial or otherwise, of the Company or its domestic subsidiaries or the ability of the Company to perform its obligations under this Agreement; (xvi) no authorization or approval or other action by, and no notice to or filing with, the FCC is required under the Communications Act or the FCC Rules: (i) in connection with the due execution and delivery by the Company of this Agreement; or (ii) for the exercise by the Underwriter of any of its rights and remedies under this Agreement; and (xvii) the execution and delivery by the Company of this Agreement and the performance by the Company of its obligations under this Agreement (i) do not contravene the Communications Act or any FCC Rule and (ii) do not and will not result in any suspension, revocation, material impairment or non-renewal of any FCC License material to the Company's and its domestic subsidiaries' operations and business. In addition, such counsel shall state in the opinion that it has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants for the Company, and representatives of the Underwriter, at which the contents of the Registration Statement and the Prospectus and related matters were discussed and, although it is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement and the Prospectus and has not made any independent check or verification thereof, during the course of such participation, 14 15 no facts came to its attention that caused it to believe that the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as of the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; it being understood that such counsel expresses no belief with respect to the financial statements, schedules and other financial data included or incorporated by reference in, or omitted from, the Registration Statement or the Prospectus. In addition, the Underwriter shall have received on the Closing Date an opinion of the general counsel of the Company, dated the Closing Date, to the effect that each domestic subsidiary of the Company is qualified to transact business and in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole. (d) The Underwriter shall have received on the Closing Date an opinion of O'Melveny & Myers LLP, counsel for the Underwriter, dated the Closing Date, covering the matters referred to in Sections 5(c)(v), 5(c)(vii), 5(c)(x) (but only as to the statements in the Prospectus under "Description of Leap Capital Stock") and Section 5(c)(xiii) above. With respect to Section 5(c)(xiii) above, O'Melveny & Myers LLP may state that its opinion and belief are based upon its participation in a review and discussion of the Registration Statement and Prospectus and any amendments or supplements thereto and documents incorporated by reference, but are without independent check or verification, except as specified. The opinion of Latham & Watkins described in Section 5(c) above shall be rendered to the Underwriter at the request of the Company and shall so state therein. (e) The Underwriter shall have received, on each of the date hereof and the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriter, from PricewaterhouseCoopers LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information (including the pro forma financial statements) contained in the Registration Statement and the Prospectus; provided that the letter delivered on the Closing Date shall use a "cut-off date" not earlier than the date hereof. (f) "Lock-up" agreements shall have been executed and delivered by the officers and directors of the Company, each in substantially the form of Exhibit A hereto, and by Qualcomm Incorporated, in substantially the form of Exhibit A-1 hereto, relating 15 16 to sales and certain other dispositions of shares of Common Stock or certain other securities, and such agreements shall be in full force and effect on the Closing Date. The obligations of the Underwriter to purchase Additional Shares hereunder are subject to the delivery to the Underwriter on the Option Closing Date of such documents as it may reasonably request with respect to the good standing of the Company and its subsidiaries, the due authorization and issuance of the Additional Shares and other matters related to the issuance of the Additional Shares. 6. Covenants of the Company. In further consideration of the agreements of the Underwriter herein contained, the Company covenants with the Underwriter as follows: (a) To furnish to you, without charge, three conformed copies of the Registration Statement (including exhibits thereto and documents incorporated by reference) and to furnish to you in New York City, without charge, prior to 10:00 a.m. New York City time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 6(c) below, as many copies of the Prospectus, any documents incorporated by reference, and any supplements and amendments thereto or to the Registration Statement as you may reasonably request. The terms "supplement" and "amendment" or "amend" as used in this Agreement shall include all documents subsequently filed by the Company with the Commission pursuant to the Exchange Act that are deemed to be incorporated by reference in the Prospectus. (b) Before amending or supplementing the Registration Statement or the Prospectus, to furnish to you a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which you reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule. (c) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriter the Prospectus is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriter, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriter and to the dealers (whose names and addresses the Underwriter will furnish to the Company) to which Shares may have been sold by the Underwriter and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with law. (d) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request. 16 17 (e) To make generally available to the Company's security holders and to you as soon as practicable an earning statement covering the twelve-month period ending June 30, 2002 that satisfies the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder. (f) As soon as practicable following the Closing Date, to file with the Commission a post-effective amendment to the Registration Statement amending the plan of distribution section therein to add a statement to the effect that the maximum compensation to be paid to any member of the NASD in connection with any offering shall not exceed 8%, other than with respect to transactions under the Acqua Wellington Agreement. 7. Expenses. Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company shall pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company's counsel and the Company's accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Prospectus and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriter and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriter, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 6(d) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriter in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees incurred in connection with the review and qualification of the offering of the Shares by the National Association of Securities Dealers, Inc., (v) all costs and expenses incident to the quotation of the Shares on the Nasdaq National Market, (vi) the cost of printing certificates representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, and (viii) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section 7, Section 8 entitled "Indemnity and Contribution," and the last paragraph of Section 10 below, the Underwriter will pay all of its costs and expenses, including, without limitation, fees and disbursements of its counsel, stock transfer taxes payable on resale of any of the Shares by it and any advertising expenses connected with any offers it may make. 8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless the Underwriter and each person, if any, who controls the Underwriter within the meaning of either 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, any legal or other expenses reasonably incurred in connection with defending or investigating any such 17 18 action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements 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 not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Underwriter furnished to the Company in writing by the Underwriter expressly for use therein; provided, however, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of the Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased Shares, or any person controlling the Underwriter, if a copy of the Prospectus (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, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities, unless such failure is the result of noncompliance by the Company with Section 6(a) hereof. (b) The Underwriter agrees to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to the Underwriter, but only with reference to information relating to the Underwriter furnished to the Company in writing expressly for use in the Prospectus. The Company acknowledges that for purposes of this Agreement, the statements set forth in the paragraphs related to stabilization, syndicate covering transactions and passive market making and the effect thereof under the heading "Underwriting" constitute the only information furnished in writing by or on behalf of the Underwriter for inclusion in the Prospectus. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the "INDEMNIFIED PARTY") shall promptly notify the person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing, and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party 18 19 shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings 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 such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Underwriter, in the case of parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability 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 the second and third sentences of this paragraph, 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 30 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 of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. (d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 on the one hand and the Underwriter on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriter on the other hand 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 on the one hand and the Underwriter on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company on the one hand and the Underwriter on the other hand 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 19 20 the Company or by the Underwriter and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. (e) The Company and the Underwriter agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 Section 8, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the 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 (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 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 party at law or in equity. (f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Underwriter or any person controlling the Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares. 9. Termination. This Agreement shall be subject to termination by notice given by you to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either 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 that, in your judgment, is material and adverse and (b) in the case of any of the events specified in clauses 9(a)(i) through 9(a)(iv), such event, singly or together with any other such event, makes it, in the judgment of the Underwriter, impracticable to market the Shares on the terms and in the manner contemplated in the Prospectus. 10. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. 20 21 If this Agreement shall be terminated by the Underwriter because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriter for all out-of-pocket expenses (including the fees and disbursements of its counsel) reasonably incurred by the Underwriter in connection with this Agreement or the offering contemplated hereunder. 11. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 12. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York. 13. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.
