The Company shall: (i) cause to be filed, on or prior to September 30, 1998 a shelf registration statement pursuant to Rule 415 under the Act (the "Shelf Registration Statement"), relating to all then outstanding Transfer Restricted Securities, and (ii) shall use its reasonable best efforts to cause such Shelf Registration Statement to become effective on or prior to September 30, 1998 (the "Effectiveness Deadline").

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within 10 days after receipt of a request therefor, the information required by Item 507 or 508 of Regulation S-K, as applicable, of the Act for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. No Holder of Transfer Restricted Securities shall be entitled to liquidated damages pursuant to Section 4 unless and until such Holder shall have provided all such information.

SECTION 4. LIQUIDATED DAMAGES If (i) the Registration Statement required by this Agreement is not filed with the Commission on or prior to the Effectiveness Deadline, (ii) such Registration Statement has not been declared effective by the Commission on or prior to the Effectiveness Deadline (except where such delay is caused by a Holder of Transfer Restricted Securities) or (iii) the Registration Statement required by this Agreement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose without being succeeded timely by a post-effective amendment to such Registration Statement that cures such failure and that is timely declared effective (each such event referred to in clauses (i) through (iii), a "Registration Default"), then the Company hereby agrees to pay to each Holder of Transfer Restricted Securities affected thereby liquidated damages in an amount equal to 50 basis points per annum on the Liquidation Preference of Transfer Restricted Securities held by such Holder for the first 90-day period immediately following the occurrence of such Registration Default. The amount of the liquidated damages shall increase by an additional 50 basis points per annum on the Liquidation Preference of Transfer Restricted Securities with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of liquidated damages of 200 basis points per annum on the Liquidation Preference of Transfer Restricted Securities; provided, however, the Company shall in no event be required to pay liquidated damages for more than one Registration Default at any given time. Notwithstanding anything to the contrary set forth herein, (1) upon filing of the Shelf Registration Statement, in the case of (i) above, (2) upon the effectiveness of the Shelf Registration Statement, in the case of (ii) above or (3) upon the filing of a post-effective amendment to the Registration Statement or an additional Registration Statement that causes the Shelf Registration Statement to again be declared effective or made usable in the case of (iii) above, the liquidated damages payable with respect to the Transfer Restricted Securities as a result of such clause (i), (ii) or (iii), as applicable, shall cease. All accrued but unpaid liquidated damages shall be paid to the Holders entitled thereto, in the manner provided for the payment of dividends in the Certificate of Designations, on the next regular Dividend Payment Date (as defined in Section 2(a) of the Certificate of Designations). All obligations of the Company set forth in the preceding paragraph that are outstanding with respect to any then outstanding Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect thereto have been satisfied in full. SECTION 5. REGISTRATION PROCEDURES (a) Shelf Registration Statement. In connection with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 5(b) below and shall use its reasonable best efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof (as indicated in the information furnished to the Company pursuant to Section 3(b) hereof), and pursuant thereto the Company will prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof within the time periods and otherwise in accordance with the provisions hereof. (b) General Provisions. In connection with any Registration Statement and any related Prospectus required by this Agreement, the Company shall: (i) use its reasonable best efforts to keep such Registration Statement continuously effective and provide all requisite financial statements for the period specified in Section 3 of this Agreement. Upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement curing such defect, and, if Commission review is required, use its reasonable best efforts to cause such amendment to be declared effective as soon as practicable. (ii) prepare and file with the Commission such amendments and post-effective amendments to the Registration Statement as may be necessary to keep such Registration Statement effective for the period set forth in Section 3; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Act, and to comply fully with Rules 424, 430A and 462, as applicable, under the Act in a timely manner; and comply with the provisions of the Act with respect to the disposition of all securities covered by such Registration Statement during the period in accordance with the intended method or methods of distribution by the selling Holder named in such Registration Statement or supplement to the Prospectus; (iii) advise the selling Holders promptly and, if requested by such Persons, confirm such advice in writing, (A) when the Prospectus or any Prospectus supplement or post- effective amendment has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, (D) of the existence of any fact or the happening of any event known to the Company that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement in order to make the statements therein not misleading, or that requires the making of any additions to or changes in the Prospectus in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; if at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time; (iv) subject to Section 5(b)(i), if any fact or event contemplated by Section 5(b)(iii)(D) above shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; (v) furnish to UBS and each selling Holder named in any Registration Statement or Prospectus in connection with such sale, if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders in connection with such sale, if any, for a period of at least three Business Days, and the Company will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which the selling Holders of the Transfer Restricted Securities covered by such Registration Statement in connection with such sale, if any, shall reasonably object within three Business Days; a selling Holder shall be deemed to have reasonably objected to such filing if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission or fails to comply with the applicable requirements of the Act; (vi) promptly prior to the filing of any document that is to be incorporated by reference into a Registration Statement or Prospectus, provide copies of such document to the selling Holders in connection with such sale, if any, make the Company's representatives available for discussion of such document and other customary due diligence matters; (vii) make available at reasonable times for inspection by the selling Holders participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such selling Holders, all financial and other records, pertinent corporate documents of the Company and cause the Company's officers, directors and employees to supply all information reasonably requested by any such selling Holder, attorney or accountant in connection with such Registration Statement or any post- effective amendment thereto subsequent to the filing thereof and prior to its effectiveness; provided, however, no such information shall be required to be made available, unless such Selling Holders enter into customary confidentiality agreements; (viii) if requested by any selling Holders in connection with such sale, if any, promptly include in any Registration Statement or Prospectus, pursuant to a supplement or post- effective amendment if necessary, such information as such Selling Holders may reasonably request to have included therein, including without limitation, information relating to the "Plan of Distribution" of the Transfer Restricted Securities; provided, however, if the Company reasonably objects to the inclusion of such information, it shall be excluded; and make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after the Company is notified of the matters to be included in such Prospectus supplement or post-effective amendment; (ix) furnish to each selling Holder in connection with such sale, if any, without charge, at least one copy of the Registration Statement, as first filed with the Commission, and of each amendment thereto, including all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference);

the Company hereby consent to the use (in accordance with law) of the Prospectus and any amendment or supplement thereto by each of the selling Holders in connection with the offering and the sale of the Transfer Restricted Securities covered by the Prospectus or any amendment or supplement thereto; (xi) upon the request of any selling Holder, enter into such agreements (including underwriting agreements) and make such representations and warranties and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Transfer Restricted Securities pursuant to any Registration Statement contemplated by this Agreement as may be reasonably requested by any Holder of Transfer Restricted Securities in connection with any sale or resale pursuant to any Registration Statement and in such connection, the Company shall: (A) upon request of any selling Holder, furnish (or in the case of paragraphs (2) and (3), use its reasonable best efforts to cause to be furnished) to each selling Holder, upon the effectiveness of the Shelf Registration Statement: (1) a certificate, dated such date, signed on behalf of the Company by (x) the President or any Vice President and (y) a principal financial or accounting officer of the Company, confirming, as of the date thereof, such matters as the selling Holders may reasonably request; (2) an opinion, dated the date of effectiveness of the Shelf Registration Statement of counsel for the Company covering customary matters subject to customary qualifications and exceptions; and (3) a customary comfort letter, subject to and in accordance with applicable Statements on Auditing Standards and related pronouncements dated the date of effectiveness of the Shelf Registration Statement from the Company's independent accountants, in the customary form and covering matters of the type customarily covered in comfort letters to underwriters in connection with underwritten offerings; and (B) deliver such other documents and certificates as may be reasonably requested by the selling Holders to evidence compliance with clause (A) above and with any customary conditions contained in the any agreement entered into by the Company pursuant to this clause (xi); (xii) prior to any public offering of Transfer Restricted Securities, cooperate with the selling Holders and their counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions as the selling Holders may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Registration Statement; provided, however, that neither the Company shall be required to register or qualify as a foreign corporation where it is not now so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not now so subject; (xiii) in connection with any sale of Transfer Restricted Securities that will result in such securities no longer being Transfer Restricted Securities, cooperate with the selling Holders to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and to register such Transfer Restricted Securities in such denominations and such names as the selling Holders may request at least two Business Days prior to such sale of Transfer Restricted Securities; (xiv) use its reasonable best efforts to cause the disposition of the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in clause (xii) above; (xv) provide a CUSIP number for all Transfer Restricted Securities not later than the effective date of a Registration Statement covering such Transfer Restricted Securities and provide printed certificates for the Transfer Restricted Securities which are in a form eligible for deposit with the Depository Trust Company; (xvi) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders with regard to any Registration Statement, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) covering a twelve-month period beginning after the effective date of the Registration Statement (as such term is defined in paragraph (c) of Rule 158 under the Act); (xvii) make appropriate officers of the Company reasonably available to the selling Holders for meetings with prospective purchasers of the Transfer Restricted Securities and prepare and present to potential investors customary "road show" material in a manner consistent with other new issuances of other securities similar to the Transfer Restricted Securities;

Each Holder receiving a Suspension Notice hereby agrees that it will either (i) promptly destroy any Prospectuses, other than permanent file copies, then in such Holder's possession which have been replaced by the Company with more recently dated Prospectuses or (ii) deliver to the Company all copies, other than permanent file copies, then in such Holder's possession of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of the Suspension Notice. The time period regarding the effectiveness of such Registration Statement set forth in Section 3, shall be extended by a number of days equal to the number of days in the period from and including the date of delivery of the Suspension Notice to the Recommencement Date. SECTION 6. REGISTRATION EXPENSES (a) All expenses incident to the Company's performance of or compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement becomes effective, including without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all expenses of printing (including printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company; (v) all application and filing fees in connection with listing the Preferred Stock on a national securities exchange or automated quotation system pursuant to the requirements hereof; and (vi) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance). The Company will, in any event, bear its internal expenses, including the expenses of any annual audit and the fees and expenses of any special experts, retained by the Company. (b) In connection with any Registration Statement required by this Agreement, the Company will reimburse the Purchasers and the Holders of Transfer Restricted Securities being registered pursuant to the Shelf Registration Statement for the reasonable fees and disbursements of not more than one counsel, who shall be Latham & Watkins, unless another firm shall be chosen by the Holders of a majority in Liquidation Preference of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared. SECTION 7. INDEMNIFICATION (a) The Company agrees, to indemnify and hold harmless (i) each Holder and (ii) each person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) any Holder (any of the persons referred to in this clause (ii) being hereinafter referred to as a "controlling person") and (iii) the respective officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an "Indemnified Holder"), from and against any and all losses, claims, damages, liabilities, judgments, (including without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, or Prospectus (or any amendment or supplement thereto) provided by the Company to any holder or any prospective purchaser of Preferred Stock, 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, liabilities or judgments are caused by an untrue statement or omission or alleged untrue statement or omission that is based upon information relating to any of the Holders furnished in writing to the Company by any of the Holders. (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, and its directors and officers, and each person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Company, to the same extent as the foregoing indemnity from the Company to each of the Indemnified Holders, but only with reference to information relating to such Indemnified Holder furnished in writing to the Company by such Indemnified Holder expressly for use in any Registration Statement. In no event shall any Indemnified Holder be liable or responsible for any amount in excess of the amount by which the total amount received by such Indemnified Holder with respect to its sale of Transfer Restricted Securities pursuant to a Registration Statement exceeds (i) the amount paid by such Indemnified Holder for such Transfer Restricted Securities and (ii) the amount of any damages that such Indemnified Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the "indemnified party"), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the "indemnifying person") in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 7(a) and 7(b), an Indemnified Holder shall not be required to assume the defense of such action pursuant to this Section 7(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Indemnified Holder). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party, unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by a majority of the Indemnified Holders, in the case of the parties indemnified pursuant to Section 7(a), and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action (i) effected with its written consent or (ii) effected without its written consent if the settlement is entered into more than twenty business days after the indemnifying party shall have received a request from the indemnified party for reimbursement for the fees and expenses of counsel (in any case where such fees and expenses are at the expense of the indemnifying party) and, prior to the date of such settlement, the indemnifying party shall have failed to comply with such reimbursement request. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action 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 the indemnified party. (d) To the extent that the indemnification provided for in this Section 7 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Holders, on the other hand, from their sale of Transfer Restricted Securities or (ii) if the allocation provided by clause 7(d)(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 7(d)(i) above but also the relative fault of the Company, on the one hand, and of the Indemnified Holder, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Indemnified Holder, 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 the Company, on the one hand, or by the Indemnified Holder, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and judgments referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 7(a), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments 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 matter, including any action that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 7, no Holder or its related Indemnified Holders shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total received by such Holder with respect to the sale of its Transfer Restricted Securities pursuant to a Registration Statement exceeds the sum of (A) the amount paid by such Holder for such Transfer Restricted Securities plus (B) the amount of any damages which such Holder 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders' obligations to contribute pursuant to this Section 7(c) are several in proportion to the respective Liquidated Preference amount of Transfer Restricted Securities held by each of the Holders hereunder and not joint. SECTION 8. RULE 144A The Company hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding and during any period in which the Company is not subject to Section 13 or 15(d) of the Securities Exchange Act, to make available, upon request of any Holder of Transfer Restricted Securities, to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities designated by such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A. SECTION 9. "PIGGY-BACK" RIGHTS 9.1 Registration Rights. (a) Piggyback Rights. If at any time during the period commencing on September 30, 1998 until eligible for resale pursuant to 144(k), but not to exceed two years, the Company shall file a registration statement (other than on Form S-4, Form S-8, or any successor form) with the Commission, the Company shall give all the then holders of any Shares of Preferred Stock (the "Eligible Holders") at least 30 days prior written notice of the filing of such registration statement. If requested by any Eligible Holder in writing within 30 days after receipt of any such notice, the Company shall, at the Company's sole expense (other than the fees and disbursements of counsel for the Eligible Holders and the underwriting discounts payable in respect of the Shares of Preferred Stock sold by any Eligible Holder), register or qualify all or, at each Eligible Holder's option, any portion of the Shares of Preferred Stock of any Eligible Holders who shall have made such request, concurrently with the registration of such other securities, all to the extent requisite to permit the public offering and sale of the Shares of Preferred Stock through the facilities of all appropriate securities exchanges and the over-the-counter market, and will use its best efforts through its officers, directors, auditors and counsel to cause such registration statement to become effective as promptly as practicable. Notwithstanding the foregoing, if the managing underwriter of any such offering shall advise the Company in writing that, in its opinion, the distribution of all or a portion of the Shares of Preferred Stock requested to be included in the registration concurrently with the securities being registered by the Company would materially adversely affect the distribution of such securities by the Company for its own account, then the Company shall not be required to include such Shares of Preferred Stock in such registration, provided that any such reduction shall be on a pro rata basis among all selling shareholders; provided, however, (i) that in the event that the Company does not intend to include all of the requested Shares of Preferred Stock in the registration statement due to such advice received from the managing underwriter, if the Company includes in the registration statement any securities other than securities being offered by the Company for its own account, then the Company shall include any of the Shares of Preferred Stock requested to be included in such registration statement by the Eligible Holders and any such other securities on a pro rata basis and (ii) if the Company does not include all of the requested Shares of Preferred Stock in the registration statement, then, if requested by the Eligible Holders, the Company will within six months after the registration statement becomes effective file at its sole expense a new registration statement relating to those Shares of Preferred Stock which the Company did not include in the prior registration statement and the Company will use its best efforts to cause the registration statement to become effective as promptly as practical. SECTION 10. MISCELLANEOUS (a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Sections 3 hereof may result in material irreparable injury to UBS or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, UBS or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Sections 3 hereof. The Company further agree to waive the defense in any action for specific performance that a remedy at law would be adequate. (b) No Inconsistent Agreements.
