(b) In the event Total desires to participate in an offering pursuant to Section 3(a), Total may include Registrable Securities in any registration statement relating to such offering; provided that if the lead managing underwriter selected by UDS for an underwritten offering pursuant to Section 3(a) determines that marketing factors require a limitation on the number of UDS Shares to be offered and sold by the stockholders of UDS in such offering, there will be included in the offering only that number of UDS Shares (including Registrable Securities), if any, that such lead managing underwriter determines will not jeopardize the success of the offering of all UDS Shares that UDS desires to sell for its own account. In such event and provided the managing underwriter has so notified UDS in writing, the number of UDS Shares to be offered and sold by stockholders of UDS, including Total, desiring to participate in such offering will be allocated pro rata among such holders of the UDS Shares on the basis of the number of UDS Shares held by each holder and entitled to be registered (subject to any written agreements entered into prior to the date hereof between UDS and one or more holders requiring a different priority). (c) Nothing in this Section 3 will create any liability or obligation on the part of UDS to Total if UDS for any reason should decide not to file a registration statement proposed to be filed under Section 3(a) or to withdraw such registration statement subsequent to its filing, regardless of any action whatsoever that Total may have taken, whether as a result of the issuance by UDS of any notice hereunder or otherwise. (d) A request by Total to include Registrable Securities in a proposed underwritten offering pursuant to Section 3(a) will not be deemed to be a request for a demand registration pursuant to Section 4. 4. Demand Registration Rights. (a) Upon the written request by Total during the period commencing 180 calendar days after the Effective Time and ending on the earlier of (i) the first date as of which all Registrable Securities cease to be Registrable Securities and (ii) the first date as of which the Registrable Securities may be disposed of without registration under the Securities Act without compliance with the volume limitations under Rule 144 or 145 under the Securities Act (or any comparable requirements) (the "Effective Period") that UDS effect the registration with the SEC under and in accordance with the provisions of the Securities Act of all or part of the Registrable Securities (which written request will specify the aggregate number of shares of Registrable Securities requested to be registered and the means of distribution), UDS will file a Registration Statement covering Registrable Securities requested to be registered as expeditiously as possible after receipt of such request; provided, however, that UDS will not be required to take any action pursuant to this Section 4: (A) if prior to the date of such request UDS shall have effected two registrations pursuant to this Section 4; (B) if UDS has effected a registration pursuant to Section 3 within the 180-day period preceding such request; (C) if UDS shall at the time have effective a shelf registration statement pursuant to Rule 415 under the Securities Act (a "Shelf Registration Statement") pursuant to which Total could effect the disposition of Registrable Securities in the manner requested; (D) if the Registrable Securities which UDS shall have been requested to register shall have a then-current market value of less than U.S. $50,000,000, unless such registration request is for all remaining Registrable Securities; or (E) during the pendency of any Section 6(a) Period or Section 6(b) Period (each, a "Blackout Period"). provided further, however, that UDS will be permitted to satisfy its obligations under this Section 4(a) by amending (to the extent permitted by applicable Law) any registration statement previously filed by UDS under the Securities Act so that such registration statement (as amended) will permit the disposition (in accordance with the intended methods of disposition specified as aforesaid) of all of the Registrable Securities for which a demand for registration has been made under this Section 4(a). If UDS so amends a previously filed registration statement, it will be deemed to have effected a registration for purposes of this Section 4. (b) Total may distribute the Registrable Securities covered by such request by means of an underwritten offering or any other lawful means, as determined by Total. (c) A registration requested pursuant to this Section 4 will not be deemed to be effected for purposes of this Section 4 if it has not been declared effective by the SEC or become effective in accordance with the Securities Act and the rules and regulations thereunder. (d) Total may, at any time prior to the effective date of the Registration Statement relating to such registration, revoke such request by providing a written notice to UDS revoking such request. In such event, Total will reimburse UDS for all its out-of-pocket expenses incurred in the preparation, filing and processing of the Registration Statement; provided, however, that, if such revocation was based on (i) UDS's failure to comply in any material respect with its obligations hereunder or (ii) the occurrence of a Blackout Period, such reimbursement will not be required. 5. Selection of Underwriters. In connection with any underwritten offering pursuant to a Registration Statement filed pursuant to a demand made by Total under Section 4, Total will have the right to select a managing underwriter or underwriters to administer the offering, which managing underwriter or underwriters will be reasonably satisfactory to UDS. 6. Blackout Periods. (a) If (i) during the Effective Period, UDS files or proposes to file a registration statement (other than in connection with the registration of securities issuable pursuant to a continuous "at the market offering" pursuant to Rule 415(a)(4) under the Securities Act, an employee stock option, stock purchase, dividend reinvestment plan or similar plan or pursuant to a merger, exchange offer or a transaction of the type specified in Rule 145(a) under the Securities Act) with respect to any securities of UDS, and (ii) with prior notice, (A) UDS (in the case of a non-underwritten offering pursuant to such registration statement) advises Total in writing that a sale or distribution of Registrable Securities would adversely affect such offering or (B) the managing underwriter or underwriters (in the case of an underwritten offering) advise UDS in writing (in which case UDS will notify Total) that a sale or distribution of Registrable Securities would adversely affect such offering, then UDS will not be obligated to effect the filing of a Registration Statement pursuant to Section 4 during the period commencing on the date that is 30 calendar days prior to the date UDS estimates (as certified in writing by an officer of UDS to Total following a request for registration pursuant to Section 4(a)) will be the date of the filing of, and ending on the date which is 120 calendar days following the effective date of, such Registration Statement (a "Section 6(a) Period"). (b) If UDS determines in good faith that the registration and distribution of Registrable Securities (i) would materially impede, delay or interfere with any pending financing (other than a financing of the type described in Section 6(a)), acquisition, corporate reorganization or other significant transaction involving UDS or (ii) would require disclosure of non-public material information, the disclosure of which would materially and adversely affect UDS, UDS will promptly give Total written notice of such determination and will be entitled to postpone the filing or effectiveness of a Registration Statement for a reasonable period of time not to exceed 120 calendar days (a "Section 6(b) Period"); provided, however, that in connection therewith UDS will be required to deliver to Counsel to Total (as identified at such time to UDS) a general statement, signed by an officer of UDS, summarizing the reasons for such postponement and an estimate of the anticipated delay. UDS will promptly notify Total of the expiration or earlier termination of a Section 6(b) Period. (c) Notwithstanding anything in this Section 6 to the contrary, (i) the beginning of any Blackout Period will be at least 60 calendar days after the end of the prior Blackout Period and (ii) the aggregate number of days included in all Blackout Periods and all Section 7(e) Periods and Section 7(m) Periods (collectively, "Registration Hold Periods") during any consecutive 12-month period during the Effective Period will not exceed 180 calendar days. 7. Registration Procedures. If and whenever UDS is required to use commercially reasonable efforts to effect or cause the registration of any Registrable Securities under the Securities Act as provided in this Agreement, UDS will, as expeditiously as possible: (a) prepare and file with the SEC a Registration Statement with respect to such Registrable Securities on any form for which UDS then qualifies or which counsel for UDS deems appropriate, and which form is available for the sale of the Registrable Securities in accordance with the intended methods of distribution thereof (including, if so requested by Total, distributions under Rule 415 under the Securities Act pursuant to a Shelf Registration Statement), and use commercially reasonable efforts to cause such Registration Statement to become and remain effective; (b) prepare and file with the SEC amendments and post-effective amendments to such Registration Statement and such amendments to the Prospectus used in connection therewith as may be necessary to maintain the effectiveness of such registration or as may be required by the rules, regulations or instructions applicable to the registration form utilized by UDS or by the Securities Act or rules and regulations thereunder necessary to keep such Registration Statement effective for up to 90 calendar days, in the case of an underwritten offering, or 180 calendar days, in any other case (or longer period in the event of a Registration Hold Period during such 90 or 180 calendar days, as provided in this Section 7) and cause the Prospectus as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to otherwise comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement until the earlier of (i) such 90th or 180th calendar day (or longer period) and (ii) such time as all Registrable Securities covered by such Registration Statement have ceased to be Registrable Securities; provided that a reasonable time before filing a Registration Statement or Prospectus, or any amendments or supplements thereto, UDS will furnish to Total, the managing underwriter and their respective counsel for review and comment copies of all documents proposed to be filed and will not file any such documents to which any of them reasonably object prior to the filing thereof; (c) furnish to Total such number of copies of such Registration Statement and of each amendment and post-effective amendment thereto (in each case including all exhibits), any Prospectus or Prospectus supplement and such other documents as Total may reasonably request in order to facilitate the disposition of the Registrable Securities by Total (UDS hereby consenting to the use (subject to the limitations set forth in the last paragraph of this Section 7) of the Prospectus or any amendment or supplement thereto in connection with such disposition); (d) use commercially reasonable efforts to register or qualify such Registrable Securities covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions within the United States as Total reasonably requests, and do any and all other acts and things which may be reasonably necessary or advisable to enable Total to consummate the disposition in such jurisdictions of the Registrable Securities owned by Total, except that UDS will not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction where, but for the requirements of this Section 7(d), it would not be obligated to be so qualified, to subject itself to taxation in any such jurisdiction or to consent to general service of process in any such jurisdiction; (e) notify Total at any time when a Prospectus relating to any such Registrable Securities is required to be delivered under the Securities Act within the appropriate period mentioned in Section 7(b) or UDS's becoming aware that the Prospectus included in any Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing (the period during which Total is required to refrain from effective public sales or distributions in such case being referred to as a "Section 7(e) Period"), and prepare and furnish to Total a reasonable number of copies of an amendment to such Registration Statement or related Prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and the time during which such Registration Statement is required to remain effective pursuant to Section 7(b) will be extended by the number of days in the Section 7(e) Period; (f) notify Total at any time, (i) when the Prospectus or any Prospectus supplement or post- effective amendment has been filed, and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the SEC for amendments or supplements to the Registration Statement or the Prospectus or for additional information; (iii) of the issuance by the SEC of any stop order of which UDS or its counsel is aware suspending the effectiveness of the Registration Statement or any order preventing the use of a related Prospectus, or the initiation or any threats of any proceedings for such purposes; (iv) of the receipt by UDS of any written notification of the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or any threats of any proceeding for that purpose; and (v) if at any time the representations and warranties of UDS contemplated by Section 7(i)(i) cease to be true and correct in any material respect; (g) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to Total an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act, provided that UDS will be deemed to have complied with this Section 7(g) if it has satisfied the provisions of Rule 158 under the Securities Act; (h) use commercially reasonable efforts to cause all such Registrable Securities to be listed on any securities exchange or automated quotation system on which UDS Shares are then listed, if such Registrable Securities are not already so listed and if such listing is then permitted under the rules of such exchange or automated quotation system, and to provide a transfer agent and registrar for such Registrable Securities covered by such Registration Statement no later than the effective date of such Registration Statement; (i) enter into agreements (including underwriting agreements) and take all other appropriate and reasonable actions in order to expedite or facilitate the disposition of such Registrable Securities and in such connection, whether or not an underwriting agreement is entered into and whether or not the registration is an underwritten registration: (i) make such representations and warranties to Total and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in comparable underwritten offerings; (ii) obtain opinions of counsel to UDS thereof (which counsel and opinions (in form, scope and substance) will be reasonably satisfactory to the managing underwriters, if any, and TOTAL) addressed to Total and the underwriters, if any, covering the matters customarily covered in opinions requested in comparable underwritten offerings and such other matters as may be reasonably requested by Total and the managing underwriter, if any; (iii) obtain "cold comfort" letters and bring-downs thereof from UDS's independent certified public accountants addressed to TOTAL and the underwriters, if any, such letters to be in customary form and covering matters of the type customarily covered in "cold comfort" letters by independent accountants in connection with underwritten offerings; (iv) if requested, provide indemnification in accordance with the provisions and procedures of Section 10 to all parties to be indemnified pursuant to said Section; and (v) deliver such documents and certificates as may be reasonably requested by Total and the managing underwriters, if any, to evidence compliance with Section 7(f) and with any customary conditions contained in the underwriting agreement or other agreement entered into by UDS. (j) cooperate with Total and the managing underwriter or underwriters or agents, if any, to facilitate, to the extent commercially reasonable under the circumstances, the timely preparation and delivery of certificates (not bearing any restrictive legends) representing the securities to be sold under such Registration Statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or underwriters or agents, if any, or Total may request; (k) if reasonably requested by the managing underwriter or underwriters or Total, incorporate in a Prospectus supplement or post-effective amendment such information as the managing underwriters and Total agree should be included therein relating to the plan of distribution with respect to such Registrable Securities, including without limitation information with respect to the purchase price being paid by such underwriters and with respect to any other terms of the underwritten offering of the Registrable Securities to be sold in such offering and make all required filings of such Prospectus supplement or post-effective amendment as promptly as practicable upon being notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; (l) provide Total, any underwriter participating in any disposition pursuant to such Registration Statement and any attorney, accountant or other agent retained by Total or underwriter (collectively, the "Inspectors") reasonable access to appropriate officers of UDS to ask questions and to obtain information reasonably requested by any such Inspector and make available for inspection all financial and other records and other information, pertinent corporate documents and properties of any of UDS (collectively, the "Records") as may be reasonably necessary to enable them to exercise their due diligence responsibilities; provided, however, that the Records that UDS determines, in good faith, to be confidential and which it notifies the Inspectors in writing are confidential will not be disclosed to any Inspector unless such Inspector signs a confidentiality agreement reasonably satisfactory to UDS but in any event permitting disclosure by an Inspector if (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission of a material fact in such Registration Statement or (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction; provided further, however, that any decision regarding the disclosure of information pursuant to clause (i) may be made only after consultation with counsel for the applicable Inspectors. Total agrees that it will promptly, after learning that disclosure of such Records is sought in a court having jurisdiction, give notice to UDS and allow UDS, at UDS's expense, to undertake appropriate action to prevent disclosure of such Records; and (m) in the event of the issuance of any stop order of which UDS or its counsel is aware suspending the effectiveness of the Registration Statement or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any Registrable Securities included in the Registration Statement for sale in any jurisdiction, UDS will use commercially reasonable efforts promptly to obtain its withdrawal; and the period for which the Registration Statement will be kept effective will be extended by a number of days equal to the number of days between the issuance and withdrawal of any stop orders (a "Section 7(m) Period"). UDS may require Total to furnish to UDS such information regarding Total and pertinent to the disclosure requirements relating to the registration and the distribution of such securities as UDS may from time to time reasonably request in writing. Upon receipt of any notice from UDS of the happening of any event of the kind described in Section 7(e), Total will forthwith discontinue disposition of Registrable Securities pursuant to the Prospectus or Registration Statement covering such Registrable Securities until Total's receipt of the copies of the supplemented or amended Prospectus contemplated by Section 7(e), and, if so directed by UDS, Total will deliver to UDS (at UDS's expense) all copies, other than permanent file copies then in Total's possession of the Prospectus covering such Registrable Securities current at the time of receipt of such notice. 8. Registration Expenses. UDS will pay, upon the written request of Total, all reasonable expenses incident to the performance of or compliance with this Agreement, including without limitation (a) all SEC, National Association of Securities Dealers, Inc. and securities exchange registration and filing fees, (b) all printing expenses, (c) all fees and expenses incurred in connection with the listing of the Registrable Securities on any securities exchange or automated quotation system pursuant to Section 7(h), and (d) the fees and disbursements of counsel for UDS and of its independent public accountants, and Total will pay (i) any fees or expenses, disbursements of counsel to Total and (ii) all underwriting discounts and commissions and transfer taxes, if any, and all other fees, costs and expenses of Total relating to the sale or disposition of Registrable Securities pursuant to the Registration Statement. 9. Reports under the Exchange Act. UDS will: (a) file with the SEC in a timely manner all reports and other documents required of UDS under the Exchange Act; and (b) furnish to Total, during the Effective Period, forthwith upon request (i) a written statement by UDS that it has complied with the current public information and reporting requirements of Rule 144 under the Securities Act and the Exchange Act and (ii) a copy of the most recent annual or quarterly report of UDS and such other reports and documents so filed by UDS. 10. Registration Indemnification; Contribution. (a) UDS will indemnify and hold harmless Total, its officers, directors, agents, trustees, general partners and each person who controls Total (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) against all losses, claims, damages, liabilities and expenses (including reasonable attorneys' fees, disbursements and expenses) as and when incurred by such party pursuant to any actual or threatened action, suit, proceeding or investigation arising out of or based upon (i) any violation by UDS (or its officers, directors or controlling persons) of any federal or state Law, rule or regulation applicable to UDS and relating to any action required or inaction by UDS (or such other person) in connection with or relating to any Registration Statement, (ii) any untrue or alleged untrue statement of material fact contained in the Registration Statement, any Prospectus or preliminary Prospectus, or any amendment or supplement to any of the foregoing, or (iii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus or a preliminary Prospectus, in light of the circumstances then existing) not misleading, except in each case insofar as the same arise out of or are based upon any such untrue statement or omission made in reliance on and in conformity with information with respect to such indemnified party furnished in writing to UDS by such indemnified party or its counsel expressly for use therein. In connection with an underwritten offering, UDS will indemnify the underwriters thereof, their officers, directors, agents, trustees, general partners, and each person who controls such underwriters (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as provided above with respect to the indemnification of Total Notwithstanding the foregoing provisions of this Section 10(a), UDS will not be liable to Total (or any officer, director, agent, trustee or controlling person thereof), any person who participates as an underwriter in the offering or sale of Registrable Securities or any other person, if any, who controls Total or underwriter (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), under the indemnity agreement in this Section 10(a) for any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense that arises out of Total's or such other person's failure to send or deliver a copy of the final Prospectus to the person asserting the existence of an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of the Registrable Securities to such person if such statement or omission was corrected in such final Prospectus and UDS had previously furnished copies thereof to Total or such other person in accordance with this Agreement. (b) In connection with a Registration Statement, Total will furnish to UDS in writing such information, including the name and address of, and the amount of Registrable Securities held by, Total, as UDS reasonably requests for use in such Registration Statement or the related Prospectus and will indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 10(a)) UDS or any underwriter, as the case may be, and any of their respective affiliates, directors, officers, agents, trustees and controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), against any losses, claims, damages, liabilities and expenses resulting from (i) any violation by Total (or its officers, directors, agents, trustees or controlling persons) of any federal or state Law, rule or regulation relating to action required of or inaction by Total (or such other person) in connection with its offer and sale of Registrable Securities and (ii) any untrue or alleged untrue statement of a material fact contained in, or any omission or alleged omission of a material fact required to be stated in, such Registration Statement or Prospectus or any amendment or supplement to either of them or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances then existing) not misleading, but only to the extent that any such untrue statement or omission is made in reliance on and in conformity with information with respect to Total furnished in writing to UDS by Total or its counsel specifically for inclusion therein. (c) Any Person entitled to indemnification hereunder agrees to give prompt written notice to the indemnifying party after the receipt by such indemnified party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which such indemnified party may claim indemnification or contribution pursuant to this Agreement (provided that failure to give such notification will not affect the obligations of the indemnifying party pursuant to this Section 10 except to the extent the indemnifying party shall have been actually prejudiced as a result of such failure). In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it wishes, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who may not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under these indemnification provisions for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation, unless in the reasonable judgment of any indemnified party a conflict of interest is likely to exist, based on the written opinion of counsel, between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party will be obligated to pay the reasonable fees and expenses of such additional counsel. No indemnifying party, in defense of any such action, suit, proceeding or investigation, may, except with the consent of each indemnified party, consent to the entry of any judgment or entry into any settlement (which consent will not be unreasonably withheld) which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability with respect to such action, suit, proceeding or investigation to the extent the same is covered by the indemnity obligation set forth in this Section 10. No indemnified party may consent to entry of any judgment or enter into any settlement without the consent of each indemnifying party (which consent will not be unreasonably withheld). (d) If the indemnification from the indemnifying party provided for in this Section 10 is unavailable to an indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party, will contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions which resulted in such losses, claims, damages, liabilities and expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party will be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above will be deemed to include, subject to the limitations set forth in Section 10(c), any legal and other fees and expenses reasonably incurred by such indemnified party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 10(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 10(d), no underwriter will be required to contribute any amount in excess of the underwriting discount or commission applicable to the Registrable Securities underwritten by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Total's obligation to contribute is several in the proportion that the proceeds of the offering received by Total bears to the total proceeds of the offering, and not joint. If indemnification is available under this Section 10(d), the indemnifying parties will indemnify each indemnified party to the full extent provided in Section 10(a) or 10(b), as the case may be, without regard to the relative fault of said indemnifying parties or indemnified party or any other equitable consideration provided for in this Section 10(d). (e) In no event will Total be liable or required to contribute any amount under this Section 10 or otherwise in respect of any untrue or alleged untrue statement or omission or alleged omission for amounts in excess of the amount by which the total price at which the Registrable Securities of Total were offered to the public exceeds the amount of any damages which Total has otherwise been required to pay by reason of such untrue statement or omission. (f) The provisions of this Section 10 will be in addition to any liability which any indemnifying party may have to any indemnified party and will survive the termination of this Agreement. 11. Participation in Underwritten Offerings. Total may not participate in any underwritten offering pursuant to Section 2 unless Total (i) agrees to sell the Registrable Securities on the basis provided in any underwriting arrangements approved by UDS in its reasonable discretion and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.
