the commutation of any EIB Policy in accordance withSection 6.05(c)and (iv) as a consequence of the foregoing, the effective nullity of the Guarantee and the Financial Security Guarantee

Section 5.08Ownership of Insurance Instruments. (a) It has:

(i)      provided
      to the SCA Parties a written list (prepared in good faith by, and reflecting
      the best belief of, an officer of such CDS Counterparty) of (A) those credit
      default swap agreements with XLCA or Affiliates of XLCA to which such CDS
      Counterparty is party, and of which such CDS Counterparty is a beneficial
      owner, at the time it became a Party and (B) the notional amount of each
      such credit default swap agreement; or (ii)      confirmed
      in writing by an officer of such CDS Counterparty, to the best belief of
      such confirming officer, a list provided by the SCA Parties of (A) those
      credit default swap agreements with XLCA or Affiliates of XLCA to which
      such CDS Counterparty is party, and of which such CDS Counterparty is a
      beneficial owner, at the time it became a Party and (B) the notional amount
      of each such credit default swap agreement.


(b)      For an abundance of clarity, the foregoing representations and warranties contained inSection
5.08(a)only reflect the best belief of the officer of the CDS Counterparty preparing the list or confirming a list prepared by SCA. The CDS Counterparty is not making any representation or warranty that is not
qualified by the best belief of such officer, and it will not be bound by or subject to liability based on any inaccuracy contained in any such list that ultimately results from such officer’s best belief being inadvertently inaccurate.

by the SCA Parties, no broker, advisor, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission from it in connection with the Transactions based upon arrangements made by or on behalf of any of the CDS
Counterparties.

Section
6.12 CDS Counterparty
Restructuring.  Following the Closing Date (except
to the extent the Allocated  Funds, as defined below, are paid to or for the
benefit of the CDS Counterparties pursuant to clause (i) or (ii) of this Section
6.12), XLCA shall segregate and hold an aggregate
amount of  Eight Hundred and Twenty Million Dollars ($820,000,000) in cash (together
with any SCA Share Sale Proceeds and the premiums or other payments described
in the last sentence of this Section 6.12)
separately in an interest bearing account or otherwise invested as may be agreed
in writing between the SCA Parties and the Required Consenting CDS Counterparties
(together with any interest earned thereon, the “Allocated
Funds”), it being understood that such interest
bearing account or other investment vehicle described in this sentence will be
maintained at Wilmington Trust Corporation. or, if maintained  with a CDS Counterparty
or an Affiliate of a CDS Counterparty, such CDS Counterparty shall have waived
in writing its rights of set-off with respect to, and any security interest or
other lien on, the Allocated Funds, solely for purposes of (i)  commuting, terminating,
amending and/or otherwise restructuring, as applicable, existing agreements (a “CDS
Counterparty Restructuring”) pursuant to
an agreement among the  applicable SCA Parties and CDS Counterparties representing
not less than the Minimum Consenting CDS Counterparty Restructuring Threshold
and (ii) after October 15, 2008, the payment of any actual claims or losses on
existing agreements and insurance  policies issued to or for the benefit of CDS
Counterparties and, it being understood that, such funds shall not be used for

or liquidation proceeding, the  Allocated Funds shall no longer be separately
held or segregated or limited in use to the purpose stated above and shall be
part of the general assets of XLCA. XLCA shall provide quarterly reports to the
CDS Counterparties setting forth an  accounting, in reasonable detail, with respect
to the Allocated Funds and any investments maintained therein; provided,
that nothing in this Section
6.12, including the creation of the Allocated Funds,
shall (i) in any way limit the rights or claims of the CDS Counterparties, the
liabilities of the SCA Parties in respect of such claims, or the rights of the
CDS  Counterparties in respect of other assets of the SCA Parties or (ii) constitute
a waiver of any defense the SCA Parties may have with respect to any such claims
or liabilities. Notwithstanding anything else herein, no CDS Counterparty has
any  obligation to participate in the CDS Counterparty Restructuring, including,

with XLCA or Affiliates of XLCA during the period that such CDS Counterparty
forbears from exercising any Triggered Enforcement Right under such credit default
swap pursuant to
Section 6.10(b) shall
be included in the Allocated Funds. After the Closing, the SCA Parties and the
CDS Counterparties will negotiate in good faith in an effort to reach agreement

the approval by the NYID of any CDS Counterparty Restructuring will require addressing XLCA’s public finance business to the satisfaction of the NYID. The SCA Parties and the CDS Counterparties hereby agree to negotiate in good faith in an
effort to reach an agreement on the appropriate treatment of such public finance business in

Section 6.17Disclosure Schedules; Supplementation and Amendment of Schedules. The SCA Parties may, at their
option, include in the Schedules items that are not material in order to avoid any misunderstanding, and such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgement or representation that such items are
material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement.  Information disclosed in the Schedules shall constitute a disclosure for all purposes under this Agreement
notwithstanding any reference to a specific section, and all such information shall be deemed to qualify the entire Agreement and not just such section. From time to time, prior to the Closing, the SCA Parties shall have the right to supplement or

thereby.  Any such extension, waiver or amendment will promptly be provided to all CDS Counterparties in writing and, if any CDS Counterparty objects to such extension, waiver or amendment, such CDS Counterparty will have five (5) Business Days from

    to the Reinsurance Agreement and/or the individual risk cessions thereunder;
    and

WHEREAS,
    Company and Reinsurer, or their affiliates, may be parties to agreements
    other than the Reinsurance Agreement, and it is the intent of the Parties
    that this Agreement will not have any effect upon such other agreements.

NOW,

    or claims to have, own, or hold, or at any time heretofore had, owned, or

    or hold or claim to have, own, or hold, arising out of conduct or matters

    arising directly or indirectly out of, based upon, or in any way related
    to or in connection with the Reinsurance Agreement and/or the individual
    risk cessions thereunder, whether grounded in law or equity, or sounding
    in tort or contract or otherwise;provided,however,
    that the provisions of thisArticle II(a)shall

related to or in connection with the Reinsurance
    Agreement and/or the individual risk cessions thereunder, whether grounded
    in law or equity or sounding in tort or contract or otherwise;provided,however,
    that the provisions of thisArticle II(b)shall
    not discharge obligations of the Company, which have been undertaken or imposed
    by the express terms of this Agreement or the Master Transaction Agreement
    (including the Ancillary Agreements).

(c)     The
    Parties understand that it is possible that unknown losses or claims may
    exist, or that present or future losses or claims may be underestimated in
    amounts or severity. Furthermore, the Parties expressly accept and assume
    the risk that the factual or legal assumptions made by any Party in connection
    with this Agreement may be found hereafter to be different from the true
    facts or law, and the Parties agree that this Agreement shall be and shall
    remain in full force and effect notwithstanding such differences in facts
    or law. Each Party expressly takes all of the foregoing into account in determining
    the amount of consideration to be given and paid for the giving of this Agreement,
    and a portion of the said consideration, having been bargained for between
    the Parties with the knowledge of the possibility of such unknown losses
    and claims, is given in exchange for the full accord, satisfaction and discharge
    of all such losses and claims.

(d)     Full
    payment of the Commutation Amount shall be in complete accord, satisfaction,
    settlement and commutation of any and all past, current and future liabilities
    and obligations that each Party owes or may owe to the other arising directly
    or indirectly out of or related to or in connection with the Reinsurance
    Agreement and/or the individual risk cessions thereunder and that upon payment
    of the Commutation Amount, the Reinsurance Agreement shall be terminated
    as of the Effective Date and neither Party shall have any further obligation
    or liability to the other Party under the Reinsurance Agreement and/or the
    individual risk cessions thereunder.

ARTICLE III

(a)     This
    Agreement fully and finally resolves the rights, duties and obligations of
    the Company and the Reinsurer under the Reinsurance Agreement, and neither
    Party shall:

(i)      have
      any remedy in respect of any representation, warranty or undertaking of
      the other that is not specifically set forth in this Agreement, the Master
      Transaction Agreement, or the Ancillary Agreements commuting the reinsurance
      agreements listed in Part I of Schedule 2.01 of the Master Transaction
      Agreement, whether or not relied upon by the other Party; or (ii)     seek
      to reopen or set aside this Agreement or the Reinsurance Agreement on any
      basis whatsoever, including, without limitation, that this Agreement or
      the Reinsurance Agreement is void or voidable due to a mistake or change
      in law or a unilateral or mutual mistake of fact in any way related to
      this Agreement or the Reinsurance Agreement.

    predecessors, successors and assigns. Each Party acknowledges that it has
    carefully read, and that it understands the scope and effect of this Agreement
    and has had a full and fair opportunity to consult with, and seek the advice
    and recommendations of its attorneys, actuaries and other professional advisors
    prior to its execution of this Agreement.

    Agreement and the negotiations and proceedings leading to this Agreement
    shall not form the basis of any claim by either Party against the other Party

    of the other Party, except with respect to an action for enforcement of this
    Agreement or the Master Transaction Agreement (including the Ancillary Agreements).

FORM OF EXCESS OF LOSS COMMUTATION AGREEMENT































Exh. 1.01(d)-1

COMMUTATION AND RELEASE AGREEMENT

This
    Commutation and Release Agreement (the “Agreement”)
    dated as of ________, 2008, is made by and between XL Financial Assurance
    Ltd, a company domiciled in Bermuda (the “Company”)
    and XL Insurance (Bermuda) Ltd, formerly known as XL Insurance Ltd, a company
    also domiciled in Bermuda ( the
  “Reinsurer”).
  The Reinsurer and the Company are hereinafter referred to collectively as the “Parties.”

RECITALS

WHEREAS,
    the Parties previously entered into a reinsurance agreement entitled the
    Excess of Loss Reinsurance Agreement executed on October 3, 2001, as amended,
    pursuant to which the Reinsurer agreed to reinsure certain liabilities of
    the Company (the “ReinsuranceAgreement”);
    and

WHEREAS,
    the vast majority of the Reinsurer’s exposure under the Reinsurance
    Agreement is attributable to a Facultative Quota Share Reinsurance Treaty
    dated as of October 6, 1999 as amended and restated by an Amended and Restated
    Facultative Quota Share Reinsurance Treaty dated as of June 22, 2001, as
    further amended and restated by a Second Amended and Restated Facultative
    Quota Share Reinsurance Treaty dated as of May 1, 2004, and as further amended
    and restated by a Third Amended and Restated Facultative Quota Share Reinsurance
    Treaty dated as of June 29, 2006 (the “Quota
    Share”) pursuant to which the Company
    reinsures certain liabilities of XL Capital Assurance Inc. (“XLCA”);
    and

WHEREAS,
    the Parties and XLCA are parties to that certain Master Commutation, Release
    and Restructuring Agreement, dated as of July __, 2008, by and among the
    Company, the Reinsurer, Security Capital Assurance Ltd and other parties
    thereto (the “Master Transaction Agreement”),
    pursuant to which (a) the Company and the Reinsurer have agreed to enter
    into this Agreement; and (b) XLCA and the Company have agreed to commute
    the Quota Share and fully and finally extinguish all of the parties’ rights
    and obligations under the Quota Share (the “Quota
    Share Commutation”); and

WHEREAS,
    the Reinsurer believes it is entitled to terminate the Reinsurance Agreement
    upon thirty (30) days notice and to seek reimbursement of the monies it previously
    paid under the Reinsurance Agreement based upon its belief that the Company
    used an improper “Threshold Amount” for purposes of calculating
    the “Liability Amount” under the Reinsurance Agreement, and the
    Company believes that the Reinsurer has no such entitlement and confirms
    its position that it had used the proper Threshold Amount for purposes of
    calculating the Liability Amount under the Reinsurance Agreement (the “Dispute”);
    and

WHEREAS,
    the Parties agree that it is in each of their best interests to freely and
    voluntarily enter into this Agreement and the Master Transaction Agreement
    and to settle the Dispute and to fully and forever release and discharge
    each other from their respective existing and future liabilities and obligations,
    including contingent and uncertain liabilities, both known

Exh. 1.01(d)-2


---



and unknown, under the Reinsurance Agreement
    and to compromise, resolve and settle all amounts due, or which may become
    due, between each other arising out of, in respect of, or relating to the
    Reinsurance Agreement; and

WHEREAS,
    the Company has agreed that it will pay the Commutation Amount it receives
    under this Agreement as part of the consideration it pays to XLCA under the
    Quota Share Commutation;

WHEREAS,
    the Company and the Reinsurer, or their affiliates, may be parties to agreements
    other than the Reinsurance Agreement, and it is the intent of the Parties
    that this Agreement will not have any effect upon such other agreements.

NOW,
      THEREFORE, in consideration of the covenants,
      conditions, promises and releases contained herein, and for other valuable
      consideration, the receipt and sufficiency of which is hereby acknowledged,
      the Parties agree as follows:

ARTICLE I

    promises, liabilities, claims, counterclaims, demands, damages, controversies,
    losses, costs and expenses (including attorneys’ fees and costs actually
    incurred) of any kind, character, description or nature whatsoever, known
    or unknown to either or both Parties, suspected or unsuspected, reported
    or unreported, fixed or contingent, which the Company now has, owns or holds
    or claims to have, own, or hold, or at any time heretofore had, owned, or
    held or claimed to have

Exh. 1.01(d)-3


---



had, owned, or held, or may hereafter
    have, own, or hold or claim to have, own, or hold, arising out of conduct
    or matters occurring on, prior to or subsequent to the Effective Date, against
    the Reinsurer, arising directly or indirectly out of, based upon, or in any
    way related to or in connection with the Reinsurance Agreement, whether grounded
    in law or equity, or sounding in tort or contract or otherwise;provided,however,
    that the provisions of thisArticle II(a)shall
    not discharge obligations of the Reinsurer, which have been undertaken or
    imposed by the express terms of this Agreement or the Master Transaction
    Agreement (including the Ancillary Agreements).

(b)     Contemporaneous
    with the payment of the Commutation Amount to the Company, the Reinsurer,

    and unconditionally releases and forever discharges the Company, its shareholders,
    parents, subsidiaries and affiliates, and their respective predecessors,
    successors, assigns, officers, directors, agents, employees, shareholders,
    representatives, and attorneys from any and all present and future actions,
    causes of action, suits, debts, liens, contracts, rights, agreements, obligations,
    promises, liabilities, claims, counterclaims, demands, damages, controversies,
    losses, costs and expenses (including attorneys’ fees and costs actually
    incurred) of any kind, character, description or nature whatsoever, known
    or unknown to either or both Parties, suspected or unsuspected, reported
    or unreported, fixed or contingent, which the Reinsurer now has, owns, holds
    or claims to have, own, or hold, or at any time heretofore had, owned, or
    held or claimed to have had, owned, or held, or may hereafter have, own,
    or hold or claim to have, own, or hold, arising out of conduct or matters
    occurring on, prior to or subsequent to the Effective Date, against the Company,
    arising directly or indirectly out of, based upon, or in any way related
    to or in connection with the Reinsurance Agreement, whether grounded in law
    or equity or sounding in tort or contract or otherwise;provided,however,
    that the provisions of thisArticle II(b)shall
    not discharge obligations of the Company, which have been undertaken or imposed
    by the express terms of this Agreement or the Master Transaction Agreement
    (including the Ancillary Agreements).

(c)     The
    Parties understand that it is possible that unknown losses or claims may
    exist, or that present or future losses or claims may be underestimated in
    amounts or severity. Furthermore, the Parties expressly accept and assume
    the risk that the factual or legal assumptions made by any Party in connection
    with this Agreement may be found hereafter to be different from the true
    facts or law, and the Parties agree that this Agreement shall be and shall
    remain in full force and effect notwithstanding such differences in facts
    or law. Each Party expressly takes all of the foregoing into account in determining
    the amount of consideration to be given and paid for the giving of this Agreement,
    and a portion of the said consideration, having been bargained for between
    the Parties with the knowledge of the possibility of such unknown losses
    and claims, is given in exchange for the full accord, satisfaction and discharge
    of all such losses and claims.

(d)     Full
    payment of the Commutation Amount shall be in complete accord, satisfaction,
    settlement and commutation of any and all past, current and future liabilities
    and obligations that each Party owes or may owe to the other arising directly
    or indirectly out of or related to or in connection with the Reinsurance
    Agreement and that upon payment of the Commutation Amount, the Reinsurance
    Agreement shall be terminated as of the Effective Date

Exh. 1.01(d)-4

    obligation or liability to the other Party under the Reinsurance Agreement.

SECTION
      2. Corporate Governance.

(a)Voting
      of SCA Shares. The SCA Shareholder Entity
      will vote the SCA Shares at each annual or special meeting of stockholders
      of SCA at which directors are to be elected, or execute proxies or written
      consents, as the case may be, in favor of (i) each SCA Shareholder Entity
      Nominee then standing for election and (ii) with respect to each other
      open board seat then standing for election that is not required to be filled
      by an SCA Shareholder Entity Nominee pursuant to Section 2(b) below, an
      individual that is Independent or, at the SCA Shareholder Entity’s
      election, an SCA Board Nominee;providedthat
      in exercising its discretion pursuant to the foregoing clause (ii), the
      SCA Shareholder Entity will vote the SCA Shares so that a majority of the
      SCA Board is at all times Independent;provided,
      however, that the SCA Shareholder Entity
      shall not vote in favor of any individual who, to the SCA Shareholder Entity’s
      knowledge (after reasonable inquiry), is either receiving or entitled to
      receive, directly or indirectly, any compensation or entitlement to indemnification,
      or is named or entitled to be named as a beneficiary under any D&O
      insurance policy, for service on the SCA Board, any SCA Board committees
      or any SCA subsidiary boards or committees from the Consenting Counterparties
      or the SCA Shareholder Entity.

(b)SCA
      Shareholder Entity Nominees.

(i)     Until
      the occurrence of a Voting Restriction Termination Event, the SCA Shareholder
      Entity will have the right to nominate for the SCA Board (i) for so long
      as the SCA Board consists of nine or fewer directors, such number of nominees
      as would equal one nominee less than a majority of the directors and (ii)
      for so long as the SCA Board consists of ten or more directors, such number
      of nominees as would equal two nominees less than a majority of the directors
      (the “SCA Shareholder Entity Nominees”);providedthat
      until the occurrence of a Voting Restriction Termination Event, the SCA
      Shareholder Entity shall at all times be entitled to nominate at least
      one nominee to the SCA Board. Such SCA Shareholder Entity Nominees will
      be allocated among the classes of the SCA Board as follows: (i) two to
      the “Class I” directors and (ii) one each to the “Class
      II” directors and “Class III” directors (or as substantially
      equivalent thereto if for any reason the SCA Board consists of more or
      fewer than nine directors), in each case, as such “classes” of
      directors are described in paragraph (3) of Section 8 of the Bye-Laws.
      For the avoidance of doubt, so long as the SCA Board consists of eleven


Exh. 1.01(i)-4


---



directors, the SCA Shareholder Entity will
      have the right to nominate four of the eleven directors. If, for any reason,
      there is a vacancy in the SCA Board, which vacancy is of a director so
      nominated by the SCA Shareholder Entity, SCA shall replace that directorship
      as soon as practicable with a nominee selected by the SCA Shareholder Entity.
      Similarly, if there is a vacancy created by an increase in the number of
      directors, then such vacancy shall be filled in a manner consistent with
      the SCA Shareholder Entity’s rights set forth in this Section 2(b)(i).
      Moreover, if the size of the SCA Board is at any time reduced, the SCA
      Shareholder Entity shall cause such number of SCA Shareholder Entity Nominees,
      if any, in excess of those to which the SCA Shareholder Entity is entitled
      based on the reduced size of the SCA Board to resign from the SCA Board
      and any directorships they hold with subsidiaries of SCA. All SCA Shareholder
      Entity Nominees shall be Independent and shall be designated for nomination
      in accordance with Section 1.2.3 of Schedule B of the Declaration of Trust.
      SCA shall, subject to Section 2(b)(vi), take all action reasonably necessary
      to appoint the initial SCA Shareholder Entity Nominees to the SCA Board
      as promptly as practicable following the execution and delivery hereof. (ii)     SCA
      shall include the SCA Shareholder Entity Nominees in each slate of directors
      proposed, recommended or nominated for election by SCA or the SCA Board,
      and will use the same efforts to cause the election of such nominees as
      it uses for the SCA Board Nominees in connection with that election (it
      being understood that for so long as the SCA Board shall remain classified
      under the Act, this Section 2(b)(ii) shall apply to only the SCA Shareholder
      Entity Nominees assigned to the appropriate “class” then up
      for election). (iii)     SCA
      agrees that each SCA Shareholder Entity Nominee shall be entitled to receive
      compensation and indemnification from SCA and its subsidiaries, and to
      be covered by D&O insurance policies of SCA and its subsidiaries, on
      the same terms as the SCA Board Nominees who are Independent. The SCA Shareholder
      Entity agrees that no SCA Shareholder Entity Nominee shall receive, directly
      or indirectly, any compensation or entitlement to indemnification, or be
      named as a beneficiary under any D&O insurance policy, for service
      on the SCA Board, any SCA Board committees or any SCA subsidiary boards
      or committees from the Consenting Counterparties or the SCA Shareholder
      Entity. (iv)     Notwithstanding
      any provision of SCA’s Corporate Governance Guidelines and any confidentiality
      undertaking by the SCA Shareholder Entity or any SCA Shareholder Entity
      Nominee to the contrary, the parties acknowledge and agree that each SCA
      Shareholder Entity Nominee (i) is hereby authorized to disclose information
      to the SCA Shareholder Entity and its Representatives, (ii) is under no
      obligation


Exh. 1.01(i)-5


---



to communicate any information received
      from the SCA Shareholder Entity or any of its Representatives to the SCA
      Chairman or any other Person and (iii) is authorized to initiate communications,
      directly or indirectly, with the SCA Shareholder Entity and its Representatives
      without any requirement to first pre-clear such communications with the
      SCA Chairman or any other Person, in each case, to the extent such SCA
      Shareholder Entity Nominee determines in good faith that the taking or
      the failure to take any such actions will not be inconsistent with his
      or her fiduciary duties to SCA under applicable law. For the avoidance
      of doubt, the provisions of the immediately preceding sentence shall not
      apply to disclosures to or communications with the Consenting Counterparties
      or their Representatives. SCA shall, effective as of the date hereof, amend
      SCA’s Corporate Governance Guidelines to extent necessary so that
      SCA’s Corporate Governance Guidelines do not contain any provisions
      inconsistent with the second preceding sentence. (v)     Until
      the occurrence of a Voting Restriction Termination Event, the SCA Shareholder
      Entity will not form or join a “group”
    within the meaning of Section 13(d)(3) of the Exchange Act with any other
    Person, including without limitation any of the Consenting Counterparties,
    for the purpose of seeking to elect more than the number of SCA Shareholder
    Entity Nominees to which it is then entitled under Section 2(b)(i);providedthat,
    subject to Section 2(a), the foregoing shall in no way prohibit the SCA Shareholder
    Entity from voting any securities of SCA in its discretion (including in
    connection with any election contest) or otherwise independently exercising
    its rights as a stockholder of SCA. (vi)     The
      SCA Shareholder Entity agrees not to nominate any individual that SCA’s
      Nominating & Governance Committee, after having the opportunity to
      conduct a reasonable inquiry, reasonably determines in the good faith discharge
      of its fiduciary duties (i) does not meet the requirements set forth in
      the penultimate sentence of Section 2(b)(i) or would be a party to or benefit
      from any arrangement that would violate the last sentence of Section 2(b)(iii)
      or (ii) does not meet the suitability criteria of the SCA Board, which
      criteria shall be consistently applied to individuals presented as SCA
      Shareholder Entity Nominees to the same extent as those presented as Independent
      SCA Board Nominees. (c)Committees;
        Subsidiary Boards. (i)     Until
      the occurrence of the Voting Restriction Termination Event, (i) the SCA
      Shareholder Entity will have the right to designate one member of the SCA
      Compensation Committee and (ii) the Compensation Committee of the SCA Board
      shall consist of at least five members which number of members shall not
      be changed without the SCA Shareholder Entity’s prior consent (subject
      to any restrictions imposed by applicable law, rule or regulation).


Exh. 1.01(i)-6


---



(ii)     Until
      the occurrence of the Voting Restriction Termination Event, (i) SCA will
      maintain a Finance and Risk Oversight Committee whose charter shall be
      substantially in its current form (with such changes thereto as may be
      agreed by a majority of the members of the Finance and Risk Oversight Committee
      and the SCA Board), (ii) the Finance and Risk Oversight Committee shall
      consist of at five members which number of members shall not be changed
      without the SCA Shareholder Entity’s prior consent, and (iii) two
      of the members of such Committee shall be SCA Shareholder Entity Nominees. (iii)     Other
      than the Audit Committee, a Compensation Committee, a Nominating & Governance
      Committee and a Finance and Risk Oversight Committee, SCA shall establish
      no other committees of the SCA Board without the prior written consent
      of at least a majority of the SCA Shareholder Entity Nominees then in office
      (which shall not unreasonably be withheld). (iv)     Subject
      to applicable law (including the Act) and New York Stock Exchange regulations,
      until the occurrence of the Voting Restriction Termination Event, upon
      the request of the SCA Shareholder Entity, SCA and the SCA Board shall
      take all actions necessary so that the composition of the board of directors,
      general partner, managing member (or controlling committee thereof) or
      any other board or committee serving a similar function with respect to
      each of SCA’s Material Subsidiaries (each a “Subsidiary
      Board”) shall be proportionate to the
      composition requirements of the SCA Board such that the SCA Shareholder
      Entity shall have the same proportional representation (rounded to the
      nearest whole number of directors, but in no event less than one) on each
      such Subsidiary Board and committee thereof as it has on the SCA Board. (v)     In
      each case where the SCA Shareholder Entity has the right to designate one
      or more members to any committee of the SCA Board, any Subsidiary Board
      or any committee thereof in accordance with this Section 2(c), the SCA
      Board shall select the SCA Shareholder Entity Nominee or SCA Shareholder
      Entity Nominees, as the case may be, to serve on such Subsidiary Board
      or committee in the same manner as Independent SCA Board Nominees are selected
      to serve on such Subsidiary Board or committee.


(d)Notice
      of SCA Board Meetings. In addition to any
      other notice required by the Act or the Bye-Laws, SCA shall give each SCA
      Shareholder Entity Nominee the same notice and information provided to
      any other member of the SCA Board with respect to each meeting of the SCA
      Board or any committee thereof (even if such SCA Shareholder Entity Nominee
      is not a member of such committee), at the same time such notice is first
      made available to any such other member of the SCA Board;providedthat
      if such notice and information is given

Exh. 1.01(i)-7


---



by means other than email, SCA shall, simultaneously
    with the giving of such notice and information by such other means, deliver
    such notice and information to each SCA Shareholder Entity Nominee by email
    to the email address of such SCA Shareholder Entity Nominee provided to SCA.

(e)Approval
      of Certain Matters. In addition to any other
      actions or approvals required under the Act or the Bye-Laws, each of SCA
      and the Shareholder Entity Nominee agree that until the occurrence of the
      Voting Restriction Termination Event, (i) the acquisition, sale, lease
      or transfer of all or substantially all of the assets of SCA, (ii) the
      discontinuance or redomestication of SCA out of Bermuda to another jurisdiction,
      (iii) mergers or amalgamations and (iv) the liquidation, dissolution or
      winding-up of SCA shall, in each case, require, as a condition to consummation
      thereof, the approval by the affirmative vote of at least sixty-six and
      two-thirds percent (66 2/3%) of the votes cast in accordance with the provisions
      of the Bye-Laws;providedthat
      this Section 2(e) shall not apply to the approval of any of the Transactions
      (as such term is defined in the Master Restructuring Agreement).

SECTION
      3. Certain Additional Agreements.

(a)No
      Voting Reduction of SCA Shares. SCA hereby
      acknowledges and agrees that for purposes of Section 44 of the Bye-Laws,
      (x) clause (ii) of paragraph (1) of Section 44 of the Bye-Laws applies
      to the transfer of the SCA Shares by XLI to the SCA Shareholder Entity
      and, in accordance with such clause, no reduction in votes contemplated
      by Section 44 of the Bye-Laws shall occur with respect to the SCA Shares
      or any other Common Shares acquired by the SCA Shareholder Entity (or any
      Affiliate thereof) for so long as the SCA Shareholder Entity (or any Affiliate
      thereof) continues to hold such shares, (y) the Master Restructuring Agreement
      shall be deemed to constitute for all purposes of Section 44 of the Bye-Laws
      the notice required to be delivered by XLI to the SCA Board pursuant clause
      (ii) of paragraph (1) of Section 44 of the Bye-Laws in connection with
      the transfer of the SCA Shares and no other condition as to the applicability
      of such clause is required to be satisfied and (z) the SCA Shareholder
      Entity (and its Affiliates) are entitled to the full benefit of clause
      (ii) of paragraph (1) of Section 44 of the Bye-Laws (including as to the
      applicability of such benefit to Section 45 of the Bye-Laws).

(b)Applicability
      of Paragraph (2) of Bye-Law 44. The SCA Shareholder
      Entity agrees that paragraph (2) of Section 44 of the Bye-Laws shall apply
      to the SCA Shareholder Entity on amutatis
      mutandisbasis as though the SCA Shareholder
      Entity were XL for purposes of such paragraph.

(c)Information
      Rights. Until the occurrence of the Voting
      Restriction Termination Event, SCA shall furnish or make available to the
      SCA Shareholder Entity, promptly after such information becomes available
      to SCA:

Exh. 1.01(i)-8


---



(i)     such
      annual budget, business plans and financial forecasts as are customarily
      provided to the SCA Board; (ii)     following
      the end of each fiscal quarter and fiscal year of SCA, such consolidated
      financial statements and operations reports of SCA (including audit reports
      with respect to fiscal years) as are customarily provided to the SCA Board;
      and (iii)     all
      information that is provided to members of the Finance and Risk Oversight
      Committee in their capacity as such.


(d)Access.
    Until the occurrence of the Voting Restriction Termination Event, SCA will,
    and will cause its subsidiaries, officers, directors and employees to, afford
    that SCA Shareholder Entity and its Representatives the opportunity to discuss
    SCA’s and its subsidiaries’ affairs, finances and accounts with
    SCA’s and its subsidiaries’ officers from time to time as the
    SCA Shareholder Entity may reasonably request, in each event, only to the
    extent necessary or reasonably appropriate to accomplish the reasonable purpose
    of the proposed inspection.

(e)Confidentiality.

(i)     The
      SCA Shareholder Entity shall not, and shall not permit any of its Representatives
      to, disclose any information of a known confidential nature received from
      SCA or any of its subsidiaries in connection with the SCA Shareholder Entity’s
      investment in SCA (“Confidential Information”). The
      SCA Shareholder Entity may disclose Confidential Information to its Representatives
      so long as such Representatives are informed by the SCA Shareholder Entity
      of the confidential nature of such information and provided that in any
      event the SCA Shareholder Entity will be responsible for any breach of
      this Section 3(e) by its Representatives. For the avoidance of doubt, the
      SCA Shareholder Entity shall not disclose any Confidential Information
      to the Consenting Counterparties or any of their respective Representatives; provided that
      a Person that serves as an accountant, counsel, consultant, advisor, agent
      and/or other representative to both a Consenting Counterparty and the SCA
      Shareholder Entity shall not be deemed to be a Representative of such Consenting
      Counterparty if (A) such Person is not acting as a Representative of such
      Consenting Counterparty in connection with the transactions contemplated
      by the Master Restructuring Agreement and (B) internal information barriers
      customary for the applicable industry are established as may be reasonably
      necessary to prevent the unauthorized disclosure of Confidential Information
      between such Person and any Person serving as a Representative to such
      Consenting Counterparty with respect to the transactions contemplated by
      the Master Restructuring Agreement.


Exh. 1.01(i)-9


---



(ii)     “Confidential
      Information” shall not include information (A) that is or becomes
      generally known on a non-confidential basis from a source other than the
      SCA Shareholder Entity or its Representatives, (B) that has become available
      to the SCA Shareholder Entity on a non-confidential basis from a source
      that is not, to the SCA Shareholder Entity’s knowledge, under an
      obligation of confidentiality or (C) that has been developed by or on behalf
      of the SCA Shareholder Entity or any of its Representatives independently
      of any disclosure from SCA or its subsidiaries. (iii)     If
      the SCA Shareholder Entity or any of its Representatives is legally requested
      or required under an order or subpoena issued by a court, administrative
      agency or arbitration panel, or to comply with regulatory or ratings agency
      requests or requirements (through oral examination, interrogatories, requests
      for information or documents, civil investigation demand or other legal,
      administrative or arbitration processes) to disclose any Confidential Information,
      such Person being so requested or required to disclose such Confidential
      Information shall use reasonable efforts to give SCA such request or requirement
      prompt written notice of the request, requirement, subpoena or order to
      permit (to the extent reasonable) SCA (if it so elects at its expense)
      to seek an appropriate protective order preventing or limiting disclosure
      or waive compliance with the provisions of this Section 3(e). If, in the
      absence of such protective order or waiver, the SCA Shareholder Entity
      or any of its Representatives is compelled to disclose Confidential Information,
      such Person may disclose such Confidential Information without liability
      hereunder. (iv)     The
      SCA Shareholder Entity agrees that money damages would not be a sufficient
      remedy for any breach of this Section 3(e) and that, in addition to all
      other remedies, SCA shall be entitled to specific performance and injunctive
      or other equitable relief as a remedy for any such breach. (v)     The
      SCA Shareholder Entity acknowledges that any information provided to the
      SCA Shareholder Entity or any of its Representatives by SCA pursuant to
      Section 3(c) or Section 3(d) may constitute material non-public information
      and that its possession of such information may subject the SCA Shareholder
      Entity to the restrictions imposed by federal and state securities laws
      on Persons in possession of material non-public information. (f)Constituent
        Documents. (i)     SCA
      shall take or cause to be taken all lawful action necessary or appropriate
      to ensure that none of SCA’s Memorandum of Association, Bye-Laws,
      Corporate Governance Guidelines and any other


Exh. 1.01(i)-10


---



similar documents of SCA and any of the
      corresponding constituent documents of SCA’s subsidiaries contain
      any provisions inconsistent with this Agreement or which would in any way
      nullify or impair the terms of this Agreement or the rights of the SCA
      Shareholder Entity hereunder. (ii)     Until
      the occurrence of the Voting Restriction Termination Event, SCA shall not,
      without the prior written consent of the SCA Shareholder Entity, amend,
      alter or repeal its Memorandum of Association, Bye-Laws, Corporate Governance
      Guidelines and any other similar document of SCA in any manner adverse
      to the SCA Shareholder Entity. SECTION 4.
        Miscellaneous.


(a)Interpretation.
    In this Agreement, the SCA Shareholder Entity shall be deemed to be the Trust,
    the Trustee (or any trustee or trustees of the Trust) acting in its capacity
    as such trustee, in each case as the context may require to be most protective
    of the interests of SCA.

(b)Termination.
    This Agreement (except for the provisions of Sections 3(a) and 3(e)) shall
    terminate upon the occurrence of the Voting Restriction Termination Event
    at which time the SCA Shareholder Entity shall cause the SCA Shareholder
    Entity Nominees to resign from the SCA Board and all directorships they hold
    in subsidiaries of SCA.

(c)Amendment
      and Waiver. This Agreement may not be amended
      except by an instrument in writing signed on behalf of each of the SCA
      and the SCA Shareholder Entity. Any party hereto may waive any right of
      such party hereunder by an instrument in writing signed by such party and
      delivered to the other party. The failure of any party to enforce any of
      the provisions of this Agreement shall in no way be construed as a waiver
      of such provisions and shall not affect the right of such party thereafter
      to enforce each and every provision of this Agreement in accordance with
      its terms.

(d)Severability.
    If any provision of this Agreement shall be declared by any court of competent
    jurisdiction to be illegal, void or unenforceable, all other provisions of
    this Agreement shall not be affected and shall remain in full force and effect.

(e)Entire
      Agreement. This Agreement embodies the complete
      agreement and understanding among the parties hereto with respect to the
      subject matter hereof and supersedes and preempts any prior understandings,
      agreements or representations by or among the parties, written or oral,
      that may have related to the subject matter hereof in any way.

(f)Successors
      and Assigns. Neither this Agreement nor any
      right or obligation hereunder is assignable in whole or in part by any
      party without the prior written consent of the other party hereto;provided,
      that the SCA

Exh. 1.01(i)-11


---



Shareholder Entity may assign any or all
    its rights under this Agreement to one or more of its Affiliates;provided,further,
    that no such assignment shall relieve the SCA Shareholder Entity of any of
    its obligations hereunder and all Common Shares held by any subsidiary or
    Affiliate of the SCA Shareholder Entity shall be deemed to be held by the
    SCA Shareholder Entity for all purposes under this Agreement.

(g)Counterparts;
      Execution by Facsimile Signature. This Agreement
      may be executed in any number of counterparts, each of which shall be an
      original, but all of which together shall constitute one instrument. This
      Agreement may be executed by facsimile signature(s).

ARTICLE II

REGISTRATION RIGHTS

Section
    2.1Demand
    Registrations. (a) Subject to Section 2.1(h),
    at any time and from time to time, the Holders’ Representative shall
    have the right by delivering a written notice to the Company (a “Demand
    Notice”) to require the Company to,
    pursuant to the terms of this Agreement, register under and in accordance
    with the provisions of the Securities Act the number of Registrable Securities
    Beneficially Owned by Holders and requested by such Demand Notice to be so
    registered (a“Demand
    Registration”);provided,however,
    that a Demand Notice may only be made if the amount of Registrable Securities
    requested to be registered is either (i) at least 20% of the aggregate number
    of Registrable Securities then held by all Holders or (ii) reasonably expected
    to generate aggregate gross proceeds on sale (prior to deducting underwriting
    discounts and commissions and offering expenses) of at least $10 million.
    A Demand Notice shall also specify the expected method or methods of disposition
    of the applicable Registrable Securities. Following receipt of a Demand Notice,
    the Company shall use its reasonable best efforts to file, as promptly as
    reasonably practicable, but not later than, 60 days with respect to any underwritten
    offering, or 30 days with respect to any other offering, after receipt by
    the Company of such Demand Notice (subject to paragraph (e) of this Section
    2.1), a Registration Statement relating to the offer and sale of the Registrable
    Securities requested to be included therein by the Holders thereof in accordance
    with the methods of distribution elected by such Holders (a“Demand
    Registration Statement”)
    and shall use its reasonable best efforts to cause such Registration Statement
    to be declared effective under the Securities Act as promptly as practicable
    after the filing thereof.

Exh. 1.01(j)-5

---



(b)No
    securities shall be included under any Demand Registration Statement related
    to an underwritten offering without the written consent of the Holders’ Representative,
    except Registrable Securities requested to be included therein pursuant to
    Section 2.1(a) . Subject to the preceding sentence, if any of the Registrable
    Securities to be registered pursuant to a Demand Registration are to be sold
    in a firm commitment underwritten offering, and the managing underwriter(s)
    of such underwritten offering advise the Holders in writing that it is their
    good faith opinion that the total number or dollar amount of Registrable
    Securities proposed to be sold in such offering, together with any Other
    Securities proposed to be included by holders thereof which are entitled
    to include securities in such Registration Statement, exceeds the total number
    or dollar amount of such securities that can be sold without having an adverse
    effect on the price, timing or distribution of the Registrable Securities
    to be so included together with all such Other Securities, then there shall
    be included in such firm commitment underwritten offering the number or dollar
    amount of Registrable Securities and such Other Securities that in the opinion
    of such managing underwriter(s) can be sold without so adversely affecting
    such offering, and such number of Registrable Securities and Other Securities
    shall be allocated for inclusion as follows:

(i)first,
      the Registrable Securities for which inclusion in such demand offering
      was requested by the Holders,pro rata(if
      applicable), based on the number of Registrable Securities Beneficially
      Owned by each such Holder; and (ii)second,
      among any holders of Other Securities,pro
      rata, based on the number of Other Securities
      Beneficially Owned by each such holder.


(c)The
    Holders collectively shall be entitled to request no more than three Demand
    Registrations pursuant to this Section 2.1;provided,however,
    that (i) in no event shall the Company be required to effect more than one
    Demand Registration in any three-month period and (ii) subject to Section
    2.1(h), in case the Company shall receive from the Holders’ Representative
    a Demand Notice requesting that the Company effect a registration on Form
    S-3 (provided that the Company is eligible to effect such registration on
    Form S-3 at such time), the Company shall be obligated to effect any such
    Demand Registration without regard to the number of Demand Registrations
    made.

(d)In
    the event of a Demand Registration, the Company shall use its reasonable
    best efforts to maintain the continuous effectiveness of the applicable Registration
    Statement for a period of at least 180 days after the effective date thereof
    or such shorter period in which all Registrable Securities included in such
    Registration Statement have actually been sold. For the avoidance of doubt,
    the foregoing sentence is not intended to limit the obligation of the Company
    to maintain the continuous effectiveness of the Short-Form Registration contemplated
    by Section 2.2 as required by Section 2.2.

(e)The
    Company shall be entitled to postpone (but not more than once in any six-month
    period), for a reasonable period of time, together with any postponement
    under Section 2.2(c), not in excess of 60 days (and not for periods exceeding,
    in the aggregate, 90 days during any twelve-month period), the filing or
    initial effectiveness of, or suspend the use of, a Demand Registration Statement
    if the Company delivers to the Holders’ Representative a certificate
    signed by both the Chief Executive Officer and Chief Financial Officer of
    the Company certifying that, in their good faith judgment, such registration,
    offering or use would reasonably be expected to

Exh. 1.01(j)-6

---



materially adversely affect or materially
    interfere with any bona fide and imminent material financing of the Company
    or any imminent material transaction under consideration by the Company or
    would require the disclosure of information that has not been, and is not
    otherwise required to be, disclosed to the public, the premature disclosure
    of which would materially adversely affect the Company. Such certificate
    shall contain, if requested by the Holders’
  Representative (and subject to their entering into a customary confidentiality
  obligation as to such information), a reasonably detailed statement of the
  reasons for such postponement or suspension and an approximation of the anticipated
  delay. If the Company so postpones the filing of a Registration Statement,
  the Holders’ Representative will have the right to withdraw the request
  for registration by giving written notice to the Company within ten days of
  the anticipated termination date of the postponement period, as provided in
  the notice delivered to the Holders’ Representative and such withdrawn
  registration will not count as a Demand Registration.

(f)The
    Holders’ Representative shall have the right to notify the Company
    that it has determined that the Registration Statement relating to a Demand
    Registration be abandoned or withdrawn, in which event the Company shall
    promptly abandon or withdraw such Registration Statement.

(g)No
    request for registration will count for the purposes of the limitations in
    Section 2.1(c) if: (A) the Holders’ Representative determines in good
    faith to withdraw the proposed registration prior to the effectiveness of
    the Registration Statement relating to such request due to marketing conditions
    or regulatory reasons relating to the Company, (B) the Registration Statement
    relating to such request is not declared effective within 60 days of the
    date such Registration Statement is first filed with the SEC (other than
    solely by reason of the applicable Holders having refused to proceed), (C)
    the Registration Statement is not maintained effective for the period required
    pursuant to this Section 2.1(d), (D) prior to the sale of at least 90% of
    the Registrable Securities included in the applicable registration relating
    to such request, such registration is adversely affected by any stop order,
    injunction or other order or requirement of the SEC or other Governmental
    Entity or court, (E) more than 10% of the Registrable Securities requested
    by the Holders to be included in the registration are not so included pursuant
    to Section 2.1(b), or (F) the conditions to closing specified in any underwriting
    agreement or purchase agreement entered into in connection with the registration
    relating to such request are not satisfied (other than as a result of a material
    default or breach thereunder by the applicable Holders). Notwithstanding
    anything to the contrary, the Company will pay all expenses (in accordance
    with Section 2.9) in connection with any request for registration pursuant
    to this Agreement regardless of whether or not such request counts toward
    the limitation set forth above.

(h)Notwithstanding
    anything else to the contrary in this Section 2.1, if, prior to any request
    for registration pursuant to this Section 2.1, (i) the Company shall have
    filed a Shelf Registration Statement covering all of the Registrable Securities
    in accordance with Section 2.2, (ii) the plan of distribution set forth in
    such Shelf Registration Statement includes underwritten offerings and (iii)
    the Shelf Registration Statement is effective when the Holders’ Representative
    would otherwise make a request for registration under this Section 2.1, the
    Company shall not be required to separately register any Registrable Securities
    (including, for the avoidance of doubt, any request that the Company effect
    a registration on Form S-3 pursuant to clause (ii) of Section 2.1(c)) in
    response to such request, and such request shall be deemed to be a request
    that the Company cooperate in effecting a Takedown of the Registrable Securities
    pursuant to such Shelf

Exh. 1.01(j)-7

Registration Statement. Subject to Section
    2.2(e), the Company may also register Other Securities on any such Shelf
    Registration Statement.

Section
    2.2Shelf
    Registration. (a) As promptly as practicable
    (but no later than 60 days) after the Company becomes eligible to effect
    a registration on Form S-3 (and provided that the Company is eligible to
    effect such registration at such time), the Company shall file with the SEC
    a Shelf Registration Statement providing for the registration and sale of
    all of the Registrable Securities by the Holders and shall use its reasonable
    best efforts to cause such Shelf Registration Statement to be declared effective
    under the Securities Act as soon as reasonably practicable thereafter (provided
    that the Company is eligible to effect such registration at such time).

(b)Subject
    to the Company being eligible to do so under the Securities Act, the Company
    shall use its reasonable best efforts to keep such Shelf Registration Statement
    continuously effective under the Securities Act in order to permit the Prospectus
    forming a part thereof to be usable by Holders until the earlier of (i) all
    Common Shares held by all Holders are no longer Registrable Securities and
    (ii) thedate
    as of which all Registrable Securities have been sold pursuant to the Shelf
    Registration Statement or another Registration Statement has been filed under
    the Securities Act (but in no event prior to the applicable period referred
    to in Section 4(3) of the Securities Act and Rule 174 thereunder) (such period
    of effectiveness, the “Shelf Period”).
    Subject to Section 2.2(c), the Company shall not be deemed to have used its
    reasonable best efforts to keep the Shelf Registration Statement effective
    during the Shelf Period if the Company voluntarily takes any action or omits
    to take any action that would result in Holders of Registrable Securities
    covered thereby not being able to offer and sell any Registrable Securities
    pursuant to such Shelf Registration Statement during the Shelf Period, unless
    such action or omission is required by applicable Law.

(c)The
    Company shall be entitled to postpone (but not more than once in any six-month
    period), for a reasonable period of time, together with any postponement
    under Section 2.1(e), not in excess of 60 days (and not for periods exceeding,
    in the aggregate, 90 days during any twelve-month period), the filing or
    initial effectiveness of, or suspend the use of, a Shelf Registration Statement
    if the Company delivers to the Holders’ Representative a certificate
    signed by both the Chief Executive Officer and Chief Financial Officer of
    the Company certifying that, in their good faith judgment, such registration,
    offering or use would reasonably be expected to materially adversely affect
    or materially interfere with any bona fide material financing of the Company
    or any material transaction under consideration by the Company or would require
    the disclosure of information that has not been, and is not otherwise required
    to be, disclosed to the public, the premature disclosure of which would materially
    adversely affect the Company. Such certificate shall contain, if requested
    by the Holders’ Representative (and subject to their entering into
    a customary confidentiality obligation as to such information), a reasonably
    detailed statement of the reasons for such postponement or suspension and
    an approximation of the anticipated delay.

(d)Upon
    a written request from any Holder (an “Initiating
    Holder”) to effect an offering under
    the Shelf Registration Statement (a “Takedown”),
    provided that the Company is eligible to utilize such Registration Statement
    at such time, the Company will, as soon as practicable, (x) deliver a written
    notice relating to the proposed Takedown to all other Holders and (y) promptly
    (and in any event not later than twenty days after receiving such Initiating
    Holder’s request) supplement the Prospectus included in the Shelf Registration
    Statement as would permit

or facilitate the sale and distribution of
    all or such portion of such Initiating Holder’s Registrable Securities
    as are specified in such request together with the Registrable Securities
    requested to be included in such Takedown by any other Holders who notify
    the Company in writing within ten business days after receipt of such written
    notice from the Company. If the Company and/or the holders of any Other Securities
    request inclusion of Other Securities in a Takedown, such Other Securities
    shall be included in the Takedown if, and only if, inclusion of such Other
    Securities would not be reasonably likely to delay in any material respect
    the timely effectuation of the Takedown or the sale of Registrable Securities
    pursuant to the Takedown. In the case of a request for or effectuation of
    a Takedown, all references in this Agreement to the effective date of a Registration
    Statement shall be deemed to refer to the date of pricing of such Takedown
    and all references to registration shall be deemed to refer to the Takedown.

(e)If
    any of the Registrable Securities to be sold pursuant to a Shelf Registration
    Statement are to be sold in a firm commitment underwritten offering, and
    the managing underwriter(s) of such underwritten offering advise the Holders
    in writing that it is their good faith opinion that the total number or dollar
    amount of Registrable Securities proposed to be sold in such offering, together
    with any Other Securities proposed to be included by holders thereof which
    are entitled to include securities in such Registration Statement, exceeds
    the total number or dollar amount of such securities that can be sold without
    having an adverse effect on the price, timing or distribution of the Registrable
    Securities to be so included together with all such Other Securities, then
    there shall be included in such firm commitment underwritten offering the
    number or dollar amount of Registrable Securities and such Other Securities
    that in the opinion of such managing underwriter(s) can be sold without so
    adversely affecting such offering, and such number of Registrable Securities
    and Other Securities shall be allocated for inclusion as follows:

(i)first,
      the Registrable Securities for which inclusion in such underwritten offering
      requested by the Holders,pro rata(if
      applicable), based on the number of Registrable Securities Beneficially
      Owned by each such Holder; and (ii)second,
      among any holders of Other Securities,pro
      rata, based on the number of Other Securities
      Beneficially Owned by each such holder of Other Securities.


Section
    2.3Piggyback
    Registrations. (a) If, other than pursuant
    to Section 2.1 or Section 2.2, the Company proposes or is required to file
    a registration statement under the Securities Act with respect to an offering
    of Common Shares, whether or not for sale for its own account (other than
    a registration statement (i) on Form S-4, Form S-8 or any successor forms
    thereto, (ii) filed solely in connection with any employee benefit or dividend
    reinvestment plan, or (iii) so long as a Shelf Registration Statement is
    effective and available pursuant to Section 2.2 hereof, filed solely in connection
    with the issuance or resale of Common Shares issuable upon conversion, exercise
    or exchange of any securities of the Company or any of its Subsidiaries,
    where such convertible, exercisable or exchangeable securities were issued
    in, or as part of, a financing transaction), in a manner that would permit
    registration of Registrable Securities for sale to the public under the Securities
    Act, then the Company shall give prompt written notice of such proposed filing
    at least 30 days before the anticipated filing date (the“Piggyback
    Notice”)
    to the Holders. The Piggyback Notice shall offer the Holders the opportunity
    to include in such

Exh. 1.01(j)-9

registration statement the number of Registrable
    Securities as they may request (a“Piggyback
    Registration”).
    Subject to Section 2.3(b) hereof, the Company shall include in each such
    Piggyback Registration all Registrable Securities with respect to which the
    Company has received written requests for inclusion therein within 15 days
    after notice has been given to the Holders, to permit the distribution of
    such Registrable Securities in accordance with the methods of distribution
    elected by such Holders. The Holders shall be permitted to withdraw all or
    part of the Registrable Securities from a Piggyback Registration at any time
    at least two Business Days prior to the effective date of the Registration
    Statement relating to such Piggyback Registration. The Company shall use
    its reasonable best efforts to maintain the effectiveness of the Registration
    Statement for a Piggyback Registration for a period of at least 180 days
    after the effective date thereof or such shorter period in which all Registrable
    Securities included in such Registration Statement have actually been sold.
    No Piggyback Registration shall count towards registrations required under
    Section 2.1.

(b)If
    any of the securities to be registered pursuant to the registration giving
    rise to the Holders’ rights under this Section 2.3 are to be sold in
    an underwritten offering, the Holders shall be permitted to include all Registrable
    Securities requested to be included in such registration in such offering
    on the same terms and conditions as any Other Securities included therein;provided,however,
    that if such offering involves a firm commitment underwritten offering and
    the managing underwriter(s) of such underwritten offering advise the Company
    in writing that it is their good faith opinion that the total amount of Registrable
    Securities requested to be so included, together with all Other Securities
    that the Company and any other Persons having rights to participate in such
    registration intend to include in such offering, exceeds the total number
    or dollar amount of such securities that can be sold without having an adverse
    effect on the price, timing or distribution of the Registrable Securities
    to be so included together with all Other Securities, then there shall be
    included in such firm commitment underwritten offering the number or dollar
    amount of Registrable Securities and such Other Securities that in the opinion
    of such managing underwriter(s) can be sold without so adversely affecting
    such offering, and such number of Registrable Securities and Other Securities
    shall be allocated for inclusion as follows:

(i)first,
      all Other Securities being sold by the Company for its own account or by
      any Person (other than a Holder) exercising a contractual right to demand
      registration; (ii)second,
      all Registrable Securities requested to be included by the Holders,pro
      rata(if applicable), based on the number
      of Registrable Securities Beneficially Owned by each such Holder; and (iii)third,
      among any other holders of Other Securities requesting such registration,pro
      rata, based on the number of Other Securities
      Beneficially Owned by each such holder of Other Securities.


Section
    2.4Registration
    Procedures. If and whenever the Company is
    required to use its reasonable best efforts to effect the registration of
    any Registrable Securities under the Securities Act as provided in Article
    II, the Company shall effect such registration to permit the sale of such
    Registrable Securities in accordance with the intended method or methods
    of

Exh. 1.01(j)-10

disposition thereof, and pursuant thereto
    the Company shall cooperate in the sale of the securities and shall, as expeditiously
    as possible (to the extent applicable, in the case of a Takedown):

(a)Prepare
    and file with the SEC a Registration Statement or Registration Statements
    on such form which shall be available for the sale of the Registrable Securities
    by the Holders or the Company in accordance with the intended method or methods
    of distribution thereof, and use its reasonable best efforts to cause such
    Registration Statement to become effective and to remain effective as provided
    herein;provided,however,
    that before filing a Registration Statement or Prospectus or any amendments
    or supplements thereto (excluding documents that would be incorporated or
    deemed to be incorporated therein by reference), the Company shall furnish
    or otherwise make available to the Selling Holders, their counsel and the
    managing underwriter(s), if any, copies of all such documents proposed to
    be filed, which documents will be subject to the reasonable review and comment
    of such counsel, and such other documents reasonably requested by such counsel,
    including any comment letter from the SEC, and, if requested by such counsel,
    provide such counsel reasonable opportunity to participate in the preparation
    of such Registration Statement and each Prospectus included therein and such
    other opportunities to conduct a reasonable investigation within the meaning
    of the Securities Act, including reasonable access to the Company’s
    books and records, officers, accountants and other advisors. The Company
    shall not file any such Registration Statement or Prospectus or any amendments
    or supplements thereto (excluding such documents that, upon filing, would
    be incorporated or deemed to be incorporated by reference therein) with respect
    to any registration pursuant to Section 2.1, 2.2 or 2.3 to which any Holder
    (if such Registration Statement includes Registrable Securities of such Holder),
    its counsel, or the managing underwriter(s), if any, shall reasonably object,
    in writing, on a timely basis, unless, in the opinion of the Company, such
    filing is necessary to comply with applicable Law.

(b)Prepare
    and file with the SEC such amendments and post-effective amendments to each
    Registration Statement as may be necessary to keep such Registration Statement
    continuously effective during the period provided herein and comply in all
    material respects with the provisions of the Securities Act with respect
    to the disposition of all securities covered by such Registration Statement,
    and cause the related Prospectus to be supplemented by any Prospectus supplement
    or Issuer Free Writing Prospectus as may be necessary to comply with the
    provisions of the Securities Act with respect to the disposition of the securities
    covered by such Registration Statement, and as so supplemented to be filed
    pursuant to Rule 424 (or any similar provisions then in force) under the
    Securities Act.

(c)Notify
    each Selling Holder and the managing underwriter(s), if any, promptly, and
    (if requested by any such Person) confirm such notice in writing, (i) when
    a Prospectus or any Prospectus supplement, Issuer Free Writing Prospectus
    or post-effective amendment has been filed, and, with respect to a Registration
    Statement or any post-effective amendment, when the same has become effective,
    (ii) of any request by the SEC or any other Governmental Entity for amendments
    or supplements to a Registration Statement or related Prospectus or Issuer
    Free Writing Prospectus or for additional information, (iii) of the issuance
    by the SEC of any stop order suspending the effectiveness of a Registration
    Statement or the initiation of any proceedings for that purpose, (iv) if
    at any time the representations and warranties of the Company contained in
    any agreement (including any underwriting agreement contemplated by Section
    2.4(o) below) cease to be true and correct, (v) of the receipt by the Company
    of any

Exh. 1.01(j)-11

notification with respect to the suspension
    of the qualification or exemption from qualification of any of the Registrable
    Securities for sale in any jurisdiction, or the initiation or threatening
    of any proceeding for such purpose, and (vi) of the happening of any event
    that makes any statement made in such Registration Statement or related Prospectus
    or any document incorporated or deemed to be incorporated therein by reference
    or any Issuer Free Writing Prospectus related thereto untrue in any material
    respect or that requires the making of any changes in such Registration Statement,
    Prospectus, documents or Issuer Free Writing Prospectus so that, in the case
    of the Registration Statement, it will not contain any untrue statement of
    a material fact or omit to state any material fact required to be stated
    therein or necessary to make the statements therein, not misleading, and
    that in the case of any Prospectus or Issuer Free Writing Prospectus, it
    will not contain any untrue statement of a material fact or omit to state
    any material fact necessary in order to make the statements therein, in light
    of the circumstances under which they were made, not misleading.

(d)Use
    its reasonable best efforts to avoid the issuance of any order suspending
    the effectiveness of a Registration Statement or any suspension of the qualification
    (or exemption from qualification) of any of the Registrable Securities for
    sale in any jurisdiction, or, if issued, to obtain the withdrawal or lifting
    of any such order or suspension at the reasonably earliest practicable date.

(e)If
    requested by the managing underwriter(s), if any, or the Holders of a majority
    of the Registrable Securities being sold in connection with an underwritten
    offering, promptly include in a Prospectus supplement, post-effective amendment
    or Issuer Free Writing Prospectus such information as the managing underwriter(s),
    if any, or such Holders may reasonably request in order to permit the intended
    method of distribution of such securities and make all required filings of
    such Prospectus supplement, such post-effective amendment or Issuer Free
    Writing Prospectus as soon as practicable after the Company has received
    such request.

(f)Furnish
    or make available to each Selling Holder, and each managing underwriter,
    if any, without charge, such number of conformed copies of the Registration
    Statement and each post-effective amendment thereto, including financial
    statements (but excluding schedules, all documents incorporated or deemed
    to be incorporated therein by reference, and all exhibits, unless requested
    in writing by such Holder, counsel or managing underwriter(s)), and such
    other documents, as such Holders or such managing underwriter(s) may reasonably
    request, and upon request a copy of any and all transmittal letters or other
    correspondence to or received from, the SEC or any other Governmental Entity
    relating to such offering.

(g)Deliver
    to each Selling Holder, and the managing underwriter(s), if any, without
    charge, as many copies of the Prospectus or Prospectuses (including each
    form of Prospectus and any Issuer Free Writing Prospectus related to any
    such Prospectuses) and each amendment or supplement thereto as such Persons
    may reasonably request in connection with the distribution of the Registrable
    Securities; and the Company, subject to Section 2.5(b), hereby consents to
    the use of such Prospectus and each amendment or supplement thereto by each
    of the Selling Holders and the managing underwriter(s), if any, in connection
    with the offering and sale of the Registrable Securities covered by such
    Prospectus and any such amendment or supplement thereto.

(h)Prior
    to any public offering of Registrable Securities, use its reasonable best
    efforts to register or qualify or cooperate with the Selling Holders, the
    managing underwriter(s), if any, and their respective counsel in connection
    with the registration or qualification (or exemption from such registration
    or qualification) of such Registrable Securities for offer and sale under
    the securities or “Blue Sky” laws of such jurisdictions within
    the United States as any Selling Holder or managing underwriter(s) reasonably
    requests in writing and to keep each such registration or qualification (or
    exemption therefrom) effective during the period such Registration Statement
    is required to be kept effective and to take any other action that may be
    necessary or advisable to enable such Selling Holders to consummate the disposition
    of such Registrable Securities in such jurisdiction;provided,however,
    that the Company will not be required to (i) qualify generally to do business
    in any jurisdiction where it is not then so qualified, (ii) subject itself
    to material taxation in any such jurisdiction where it is not then so subject,
    or (iii) take any action that would subject it to general service of process
    in any such jurisdiction where it is not then so subject.

(i)Cooperate
    with the Selling Holders and the managing underwriter(s), if any, to facilitate
    the timely preparation and delivery of certificates (not bearing any legends)
    representing Registrable Securities to be sold after receiving written representations
    from each Selling Holder that the Registrable Securities represented by the
    certificates so delivered by such Selling Holder will be transferred in accordance
    with the Registration Statement, and enable such Registrable Securities to
    be in such denominations and registered in such names as the managing underwriter(s),
    if any, or the Selling Holders may request at least two Business Days prior
    to any sale of Registrable Securities.

(j)Use
    its reasonable best efforts to cause the Registrable Securities covered by
    the Registration Statement to be registered with or approved by such other
    Governmental Entities within the United States, except as may be required
    solely as a consequence of the nature of such Selling Holder’s business,
    in which case the Company will cooperate in all reasonable respects with
    the filing of such Registration Statement and the granting of such approvals,
    as may be necessary to enable the seller or sellers thereof or the managing
    underwriter(s), if any, to consummate the disposition of such Registrable
    Securities.

(k)Upon
    the occurrence of any event contemplated by Section 2.4(c)(ii), (c)(iii),
    (c)(iv), (c)(v) or (c)(vi) above, prepare a supplement or post-effective
    amendment to the Registration Statement or a supplement to the related Prospectus
    or any document incorporated or deemed to be incorporated therein by reference
    or an Issuer Free Writing Prospectus related thereto, or file any other required
    document so that, as thereafter delivered to the Selling Holders, such Prospectus
    will not contain 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, in light of the circumstances under which they were made, not misleading.

(l)Prior
    to the effective date of the Registration Statement relating to the Registrable
    Securities, provide a CUSIP number for the Registrable Securities.

(m)Provide
    and cause to be maintained a transfer agent and registrar for all Registrable
    Securities covered by such Registration Statement from and after a date not
    later than the effective date of such Registration Statement.

(n)To
    the extent that the Common Shares are then listed on any national securities
    exchange, use reasonable best efforts to cause all Registrable Securities
    covered by such Registration Statement to be authorized to be listed on such
    national securities exchange, provided, however, that the Company shall have
    no obligation under this Section 2.3(n) if at the time of such registration
    the Company or Common Shares do not satisfy all criteria imposed by such
    national securities exchange to maintain such listing.

(o)Enter
    into such agreements (including an underwriting agreement in form, scope
    and substance as is customary in underwritten offerings) and take all such
    other actions reasonably requested by the Holders of a majority of the Registrable
    Securities being sold in connection therewith or by the managing underwriter(s),
    if any, to expedite or facilitate the disposition of such Registrable Securities,
    and in connection therewith, 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 the Selling Holders and the
    managing underwriter(s), if any, with respect to the business of the Company
    and its Subsidiaries, and the Registration Statement, Prospectus and documents,
    if any, incorporated or deemed to be incorporated by reference therein, in
    each case, in form, substance and scope as are customarily made by issuers
    in underwritten offerings, and, if true, confirm the same if and when requested,
    (ii) use its reasonable best efforts to furnish to the Selling Holders of
    such Registrable Securities opinions of counsel to the Company and updates
    thereof (which counsel and opinions (in form, scope and substance) shall
    be reasonably satisfactory to the managing underwriter(s), if any, and counsels
    to the Selling Holders of the Registrable Securities), addressed to each
    Selling Holder of Registrable Securities and each of the managing underwriter(s),
    if any, covering the matters customarily covered in opinions requested in
    underwritten offerings and such other matters as may be reasonably requested
    by such counsel and managing underwriter(s), (iii) use its reasonable best
    efforts to obtain “comfort” letters and updates thereof from
    the independent certified public accountants of the Company (and, if necessary,
    any other independent certified public accountants of any Subsidiary of the
    Company or of any business acquired by the Company for which financial statements
    and financial data are, or are required to be, included in the Registration
    Statement) who have certified the financial statements included in such Registration
    Statement, addressed to each Selling Holder of Registrable Securities (unless
    such accountants shall be prohibited from so addressing such letters by applicable
    standards of the accounting profession or such action is otherwise inconsistent
    with the then current practice in the accounting profession) and each of
    the managing underwriter(s), if any, such letters to be in customary form
    and covering matters of the type customarily covered in “comfort” letters
    in connection with underwritten offerings, (iv) if an underwriting agreement
    is entered into, the same shall contain customary indemnification provisions
    and procedures, except as otherwise agreed by the Holders of a majority of
    the Registrable Securities being sold in connection therewith and the managing
    underwriter(s), if any, and (v) deliver such documents and certificates as
    may be reasonably requested by the Holders of a majority of the Registrable
    Securities being sold in connection therewith, their counsel and the managing
    underwriter(s), if any, to evidence the continued validity of the representations
    and warranties made pursuant to clause (i) above and to evidence compliance
    with any customary conditions contained in the underwriting agreement or
    other agreement entered into by the Company. The above shall be done at each
    closing under such underwriting or similar agreement, or as and to the extent
    required thereunder.

(p)Upon
    execution of a customary confidentiality agreement, make available for inspection
    by a representative of the Selling Holders, the managing underwriter(s),
    if any, and any attorneys or accountants retained by such Selling Holders
    or managing underwriter(s), at the offices where normally kept, during reasonable
    business hours, financial and other records, pertinent corporate documents
    and properties of the Company and its Subsidiaries, and cause the officers,
    directors and employees of the Company and its Subsidiaries to supply all
    information in each case reasonably requested by any such representative,
    managing underwriter(s), attorney or accountant in connection with such Registration
    Statement.

(q)Cause
    its officers to use their reasonable best efforts to support the marketing
    of the Registrable Securities covered by the Registration Statement (including,
    without limitation, by participation in “road shows” and appearing
    before rating agencies) taking into account the Company’s business
    needs.

(r)Otherwise
    use its reasonable best efforts to comply with all applicable rules and regulations
    of the SEC and any applicable national securities exchange, and make available
    to its security holders, as soon as reasonably practicable (but not more
    than 18 months) after the effective date of the registration statement, an
    earnings statement which shall satisfy the provisions of Section 11(a) of
    the Securities Act.

Section
    2.5Certain
    Additional Agreements.

(a)The
    Company may require each Selling Holder to furnish to the Company in writing
    such information required in connection with such registration regarding
    such Selling Holder and the distribution of such Registrable Securities as
    the Company may, from time to time, reasonably request in writing and the
    Company may exclude from such registration the Registrable Securities of
    any Selling Holder who fails to furnish such information within a reasonable
    time after receiving such request.

(b)Each
    Selling Holder agrees that upon receipt of any notice from the Company of
    the happening of any event of the kind described in Section 2.4(c)(iii) or
    (c)(vi) hereof, such Holder will forthwith discontinue disposition of such
    Registrable Securities covered by such Registration Statement or Prospectus
    until such Holder’s receipt of the copies of the supplemented or amended
    Prospectus contemplated by Section 2.4(k) hereof, or until it is advised
    in writing by the Company that the use of the applicable Prospectus may be
    resumed, and has received copies of any additional or supplemental filings
    that are incorporated or deemed to be incorporated by reference in such Prospectus;
    provided, however, that (i) in no event shall such discontinuance exceed
    the time period set forth in Section 2.1(e) hereof, and (ii) the Company
    shall extend the time periods under Section 2.1 and Section 2.3 with respect
    to the length of time that the effectiveness of a Registration Statement
    must be maintained by the amount of time the Holder is required to discontinue
    disposition of such securities.

(c)The
    Company covenants and agrees that, so long as any Holder holds any Registrable
    Securities in respect of which any registration rights provided for in this
    Article II remain in effect, the Company will not, directly or indirectly,
    grant to any Person or agree to or otherwise become obligated in respect
    of rights of registration in the nature or substantially in the nature of
    those set forth in this Article II that would have priority over the Registrable
    Securities

with respect to the inclusion of such securities
    in any registration by the Company (other than rights granted to a new registration
    rights holder after the date hereof to exercise a contractual right to demand
    registration that have terms no more favorable than the demand registration
    rights granted to the Holders in this Agreement), without the prior written
    consent of the Holders’ Representative. The Company has not entered
    into and will not enter into any agreement that is inconsistent with the
    rights granted to the Holders in this Agreement or otherwise conflicts with
    the provisions hereof. The rights granted to the Holders hereunder do not
    in any way conflict with and are not inconsistent with the rights granted
    prior to the date hereof to the holders of any of the Company’s other
    issued and outstanding securities under any such agreements.

(d)E
    ach Holder covenants and agrees that it will comply with the prospectus delivery
    requirements of the Securities Act as applicable to it or an exemption therefrom
    in connection with sale of Registrable Securities pursuant to the Registration
    Statement.

Section
    2.6Indemnification.

(a)Indemnification
      by the Company. The Company shall indemnify
      and hold harmless, to the fullest extent permitted by Law, each Selling
      Holder whose Registrable Securities are covered by a Registration Statement
      or Prospectus, the officers, directors, partners (limited and general),
      members, managers, shareholders, accountants, attorneys, agents and employees
      of each of them, each Person who controls (within the meaning of Section
      15 of the Securities Act or Section 20 of the Exchange Act) each such Selling
      Holder and the officers, directors, partners (limited and general), members,
      managers, shareholders, accountants, attorneys, agents and employees of
      each such controlling Person, each underwriter (including any Holder that
      is deemed to be an underwriter pursuant to any SEC comments or policies),
      if any, and each Person who controls (within the meaning of Section 15
      of the Securities Act or Section 20 of the Exchange Act) such underwriter
      (collectively, “Holder Indemnitees”), from and against any
      and all losses, claims, damages, liabilities, expenses (including, without
      limitation, costs of preparation and reasonable attorneys’ fees and
      any other reasonable fees or expenses incurred by such party in connection
      with any investigation or Action), judgments, fines, penalties, charges
      and amounts paid in settlement (collectively,“Losses”),
      as incurred, arising out of or based upon any untrue statement (or alleged
      untrue statement) of a material fact contained in any applicable Registration
      Statement (or in any preliminary or final Prospectus contained therein,
      any document incorporated by reference therein or Issuer Free Writing Prospectus
      related thereto) amendment of or supplement to any of the foregoing or
      other document incident to any such registration, qualification, or compliance,
      or based on any omission (or alleged omission) to state therein (in the
      case of a final or preliminary Prospectus, in light of the circumstances
      under which they were made) a material fact required to be stated therein
      or necessary to make the statements therein not misleading, or any violation
      by the Company of the Securities Act or of the Exchange Act in connection
      with any such registration, qualification, or compliance; provided, that
      the Company will not be liable to a Selling Holder or underwriter, as the
      case may be, in any such case to the extent that any such Loss arises out
      of or is based on any untrue statement or omission by such Selling Holder
      or underwriter, as the case may be, but only to the extent, that such untrue
      statement (or alleged untrue statement) or omission (or alleged omission)
      is made in such Registration Statement (or in any preliminary or final
      Prospectus contained therein, any document incorporated by reference therein
      or Issuer Free Writing Prospectus related thereto), amendment of or supplement
      to any of the foregoing or other document in reliance upon and in conformity
      with

Exh. 1.01(j)-16

written information furnished to the Company
    by such Selling Holder or underwriter specifically for inclusion in such
    document; and provided, further, that the Company will not be liable to any
    Person who participates as an underwriter in any underwritten offering or
    sale of Registrable Securities, or to any Person who is a Selling Holder
    in any non-underwritten offering or sale of Registrable Securities, or any
    other Person, if any, who controls such underwriter or Selling Holder within
    the meaning of the Securities Act, under the indemnity agreement in this
    Section 2.6 with respect to any preliminary Prospectus or the final Prospectus
    (including any amended or supplemented preliminary or final Prospectus),
    as the case may be, to the extent that any such loss, claim, damage or liability
    of such underwriter, Selling Holder or controlling Person results from the
    fact that such underwriter or Selling Holder sold Registrable Securities
    to a Person to whom there was not sent or given, at or prior to the written
    confirmation of such sale, a copy of the final Prospectus as then amended
    or supplemented, whichever is most recent, if the Company has previously
    furnished copies thereof to such underwriter or Selling Holder and such final
    Prospectus, as then amended or supplemented, has corrected any such misstatement
    or omission. Such indemnity shall remain in full force and effect regardless
    of any investigation made by or on behalf of any Holder Indemnitee or any
    other Holder and shall survive the transfer of such securities. The foregoing
    indemnity agreement is in addition to any liability that the Company may
    otherwise have to each Holder Indemnitee.

(b)Indemnification
      by Selling Holders. In connection with any
      Registration Statement in which a Selling Holder is participating by registering
      Registrable Securities, such Selling Holder shall furnish to the Company
      in writing such information as the Company reasonably requests specifically
      for use in connection with any Registration Statement or Prospectus and
      agrees, severally and not jointly with any other Person, to indemnify and
      hold harmless, to the fullest extent permitted by Law, the Company, the
      officers and directors of the Company, and each Person who controls (within
      the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
      Act) the Company, and each underwriter, if any, and each Person who controls
      (within the meaning of Section 15 of the Securities Act or Section 20 of
      the Exchange Act) such underwriter (collectively,“Company
      Indemnitees”),
      from and against all Losses, as incurred, arising out of or based on any
      untrue statement (or alleged untrue statement) of a material fact contained
      in any such Registration Statement (or in any preliminary or final Prospectus
      contained therein, any document incorporated by reference therein or Issuer
      Free Writing Prospectus related thereto) or any amendment of or supplement
      to any of the foregoing or any other document incident to such registration,
      or 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 final or preliminary Prospectus, in light of the circumstances
      under which they were made) not misleading, in each case solely to the
      extent that such untrue statement (or alleged untrue statement) or omission
      (or alleged omission) is made in such Registration Statement (or in any
      preliminary or final Prospectus contained therein, any document incorporated
      by reference therein or Issuer Free Writing Prospectus related thereto),
      offering circular, or any amendment of or supplement to any of the foregoing
      or other document in reliance upon and in conformity with written information
      furnished to the Company by such Selling Holder expressly for inclusion
      in such document. Such indemnity shall remain in full force and effect
      regardless of any investigation made by or on behalf of the Company or
      any of its directors, officers or controlling Persons. The Company may
      require as a condition to its including Registrable Securities in any Registration
      Statement filed hereunder that the holder thereof acknowledge its agreement
      to be bound by the provisions of this Agreement (including Section 2.6)
      applicable to it.

(c)Conduct
      of Indemnification Proceedings. If any Person
      shall be entitled to indemnity hereunder (an“indemnified
      party”),
      such indemnified party shall give prompt notice to the party from which
      such indemnity is sought (the“indemnifying
      party”)
      of any claim or of the commencement of any Action with respect to which
      such indemnified party seeks indemnification or contribution pursuant hereto;
      provided, however, that the delay or failure to so notify the indemnifying
      party shall not relieve the indemnifying party from any obligation or liability
      except to the extent that the indemnifying party has been actually prejudiced
      by such delay or failure. The indemnifying party shall have the right,
      exercisable by giving written notice to an indemnified party promptly after
      the receipt of written notice from such indemnified party of such claim
      or Action, to assume, at the indemnifying party’s expense, the defense
      of any such Action, with counsel reasonably satisfactory to such indemnified
      party; provided, however, that an indemnified party shall have the right
      to employ separate counsel in any such Action and to participate in the
      defense thereof, but the fees and expenses of such counsel shall be at
      the expense of such indemnified party unless: (i) the indemnifying party
      agrees to pay such fees and expenses; (ii) the indemnifying party fails
      reasonably promptly to assume, or in the event of a conflict of interest,
      as determined after receiving written advice from outside counsel, cannot
      assume, the defense of such Action or fails to employ counsel reasonably
      satisfactory to such indemnified party, in which case the indemnified party
      shall also have the right to employ counsel and to assume the defense of
      such Action; or (iii) in the indemnified party’s reasonable judgment,
      after receiving written advice from outside counsel, a conflict of interest
      between such indemnified and indemnifying parties may exist in respect
      of such Action; provided, further, however, that the indemnifying party
      shall not, in connection with any one such 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 firm of attorneys (together with appropriate local counsel)
      at any time for all of the indemnified parties, or for fees and expenses
      that are not reasonable. Whether or not such defense is assumed by the
      indemnifying party, such indemnified party will not be subject to any liability
      for any settlement made without its written consent (but such consent will
      not be unreasonably withheld or delayed). No indemnifying party will be
      subject to any liability for any settlement made without its written consent
      (but such consent will not be unreasonably withheld or delayed). The indemnifying
      party shall not consent to entry of any judgment or enter into any settlement
      that does not include as an unconditional term thereof the giving by all
      claimants or plaintiffs to such indemnified party of a release, in form
      and substance reasonably satisfactory to the indemnified party, from all
      liability in respect of such claim or litigation.

(d)Contribution.
    (i) If the indemnification provided for in this Section 2.6 is unavailable
    to an indemnified party in respect of any Losses (other than in accordance
    with its terms), then each applicable 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, in such proportion as
    is appropriate to reflect the relative fault of the indemnifying party, on
    the one hand, and such indemnified party, on the other hand, in connection
    with the actions, statements or omissions that resulted in such Losses as
    well as any other relevant equitable considerations. The relative fault of
    such indemnifying party, on the one hand, and indemnified party, on the other
    hand, shall 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 taken by, or relates to information supplied

Exh. 1.01(j)-18

---



by, such indemnifying party or indemnified
    party, and the parties’ relative intent, knowledge, access to information
    and opportunity to correct or prevent any such action, statement or omission.

(ii)The
      parties hereto agree that it would not be just and equitable if contribution
      pursuant to this Section 2.6(d) 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 the immediately preceding paragraph. (iii)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.


(e)Limitation
      on Holder Liability. Notwithstanding anything
      to the contrary contained in this Agreement, an indemnifying party that
      is a Holder shall not be required to indemnify or contribute any amount
      in excess of the amount by which the net proceeds received by such Holder
      from the sale of the Registrable Securities sold by such Holder in the
      applicable offering exceeds the amount of any damages that such indemnifying
      party has otherwise been required to pay by reason of the applicable untrue
      or alleged untrue statement or omission or alleged omission.

Section
    2.7Rule
    144; Rule 144A. The Company covenants that
    it will file the reports required to be filed by it under the Securities
    Act and the Exchange Act and the rules and regulations adopted by the SEC
    thereunder (or, if the Company is not required to file such reports, it will,
    upon the request of any Holder, make publicly available other information
    so long as necessary to permit sales pursuant to Rule 144 or 144A under the
    Securities Act), and it will take such further action as any Holder may reasonably
    request, all to the extent required from time to time to enable such Holder
    to sell Registrable Securities without registration under the Securities
    Act within the limitation of the exemptions provided by (i) Rule 144 or 144A
    or Regulation S under the Securities Act, as such Rules may be amended from
    time to time, or (ii) any similar rule or regulation hereafter adopted by
    the SEC. Upon the request of any Holder, the Company will deliver to such
    Holder a written statement as to whether it has complied with such requirements
    and, if not, the specifics thereof.

Section
    2.8Underwritten
    Registrations. (a) If any offering of Registrable
    Securities is an underwritten offering, the Holders’ Representative
    shall have the right to select the investment banker or investment bankers
    and managers to administer the offering, subject to approval by the Company,
    not to be unreasonably withheld or delayed. The Company shall have the right
    to select the investment banker or investment bankers and managers to administer
    any incidental or piggyback registration.

(b)No
    Person may participate in any underwritten registration hereunder unless
    such Person (i) agrees to sell the Registrable Securities or Other Securities
    it desires to have covered by the registration on the basis provided in any
    underwriting arrangements in customary form (including pursuant to the terms
    of any over-allotment or “green shoe” option requested by the
    managing underwriter, provided that no such Person will be required to sell
    more than the number of Registrable Securities that such Person has requested
    the Company to include in any registration), and (ii) completes and executes
    all questionnaires, powers of attorney, indemnities,

Exh. 1.01(j)-19

underwriting agreements and other documents
    required under the terms of such underwriting arrangements, provided that
    such Person (other than the Company) shall not be required to make any representations
    or warranties other than those related to title and ownership of shares and
    as to the accuracy and completeness of statements made in a Registration
    Statement, Prospectus or other document in reliance upon and in conformity
    with written information furnished to the Company or the managing underwriter(s)
    by such Person and,provided further,
    that such Person’s (other than the Company’s) liability in respect
    of such representations and warranties shall not exceed such Person’s
    net proceeds from the offering.

Section
    2.9Registration
    Expenses. The Company shall pay all reasonable
    documented expenses incident to the Company’s performance of or compliance
    with its obligations under this Article II, including, without limitation,
    (i) all registration and filing fees (including fees and expenses (A) with
    respect to filings required to be made with the SEC, all applicable securities
    exchanges and/or the Financial Industry Regulatory Authority and (B) of compliance
    with securities or Blue Sky laws including any fees and disbursements of
    counsel for the underwriter(s) in connection with Blue Sky qualifications
    of the Registrable Securities pursuant to Section 2.4(h)), (ii) printing
    expenses (including expenses of printing certificates for Registrable Securities
    in a form eligible for deposit with The Depository Trust Company and of printing
    Prospectuses if the printing of Prospectuses is requested by the managing
    underwriter(s), if any, or by the Holders of a majority of the Registrable
    Securities included in any Registration Statement), (iii) messenger, telephone
    and delivery expenses of the Company, (iv) fees and disbursements of counsel
    for the Company, (v) expenses of the Company incurred in connection with
    any road show, and (vi) fees and disbursements of all independent certified
    public accountants (including, without limitation, the expenses of any “comfort” letters
    required by this Agreement) and any other Persons, including special experts
    retained by the Company. In addition, the Company shall bear all of its internal
    expenses (including all salaries and expenses of its officers and employees
    performing legal or accounting duties), the expense of any annual audit,
    the fees and expenses incurred in connection with the listing of the securities
    to be registered on any securities exchange on which similar securities issued
    by the Company are then listed and rating agency fees and the fees and expenses
    of any Person, including special experts, retained by the Company. In addition,
    the Company shall pay the reasonable documented fees and disbursements of
    one firm of counsel (and, if needed, one firm of local counsel) for the SCA
    Shareholder Entity (but no Transferee or any other Person) in connection
    with registrations under Article II, but the Company shall not be obligated
    to pay any underwriting discounts attributable to sales of Registrable Securities
    by any Holder including the SCA Shareholder Entity.

Section
    2.10Securities
    Held by the Company or its Subsidiaries. Whenever
    the consent or approval of Holders of a specified percentage of Registrable
    Securities is required hereunder, in the event that the Company or any of
    its Subsidiaries holds Registrable Securities, such Registrable Securities
    shall not be counted in determining whether such consent or approval was
    given by the Holders of such required percentage.

Section
    3.2Termination.
    This Agreement shall terminate at such time as there are no Registrable Securities,

    and Waiver. This Agreement may not be amended

    when the SCA Shareholder Entity is not the sole Holder, signed on behalf
    of each of (i) the Company and (ii) the Holders of a majority of the aggregate

    of this Agreement in accordance with its terms.

Section
    3.4Severability.
    If any provision of this Agreement shall be declared by any court of competent
    jurisdiction to be illegal, void or unenforceable, all other provisions of

    Agreement. Except as otherwise expressly set
    forth herein, this Agreement and the Master Transaction Agreement, together
    with the several agreements and other documents and instruments referred
    to herein or therein or annexed hereto or thereto, embody the complete agreement
    and understanding among the parties hereto with respect to the subject matter
    hereof and supersedes and preempts any prior understandings, agreements or

    stating the name and address of any Transferee and identifying the number
    of shares of Registrable Securities being acquired by the Transferee and
    with respect to which the rights under this Agreement are being transferred

together shall constitute one instrument.
    This Agreement may be executed by facsimile signature(s).

Section
    3.8Remedies.
    (a) Each party hereto acknowledges that monetary damages would not be an
    adequate remedy in the event that any of the covenants or agreements in this
    Agreement is not performed in accordance with its terms, and it is therefore
    agreed that, in addition to and without limiting any other remedy or right
    it may have, the non-breaching party will have the right to an injunction,
    temporary restraining order or other equitable relief in any court of competent
    jurisdiction enjoining any such breach or threatened breach and enforcing
    specifically the terms and provisions hereof. Each party hereto agrees to
    waive any requirement for the securing or posting of any bond in connection
    with such remedy.

(b)All
    rights, powers and remedies provided under this Agreement or otherwise available
    in respect hereof at law or in equity shall be cumulative and not alternative,

    shall not preclude the simultaneous or later exercise of any other such right,
    power or remedy by such party.

Section
    3.9Notices.

Section
      3.01.   Escrow Agent.

(a)Except
    as provided in Section 1.04, the Escrow Agent shall not transfer or otherwise
    dispose of in any manner all or any portion of the Escrow Property, except
    pursuant to an order of a court of competent jurisdiction.

(b)The
    duties and obligations of the Escrow Agent shall be determined solely by
    this Agreement, and the Escrow Agent shall not be liable, except for the
    performance of such duties and obligations as are specifically set forth
    in this Agreement.

(c)In
    the performance of its duties hereunder, the Escrow Agent shall be entitled
    to rely upon any document, instrument or signature believed by it in good
    faith to be genuine and signed by SCA or XLCA or an authorized officer or
    agent thereof, and shall not be required to investigate the truth or accuracy
    of any statement contained in any such document or instrument (including
    any document, instrument or signature executed by SCA and XLCA stating that
    the relevant action has been consented to by the Required Consenting CDS
    Counterparties). The Escrow Agent may assume that any person purporting to
    give any notice on behalf of SCA or XLCA in accordance with the provisions
    of this Agreement has been duly authorized to do so.

(d)The
    Escrow Agent shall not be liable for any error of judgment, or any action
    taken, suffered or omitted to be taken, hereunder, except in the case of
    its gross negligence or willful misconduct. The Escrow Agent may consult
    with counsel of its own choice and shall have full and complete authorization
    and protection for any action taken or suffered by it hereunder in good faith
    and in accordance with the opinion of such counsel. The Escrow Agent shall
    not be bound in any way by the Master Restructuring Agreement or any other
    agreement between the other parties to this Agreement, other than this Agreement,
    whether or not it has knowledge thereof, and the Escrow Agent’s only
    duties and responsibilities shall be to hold and to dispose of the Escrow
    Property in accordance with the terms of this Agreement.

(e)The
    Escrow Agent shall have no duty as to the collection or protection of the
    Escrow Property, nor as to the preservation of any rights pertaining thereto,
    beyond the safe custody of any such Escrow Property actually in its possession.

(f)As
    compensation for its services to be rendered under this Agreement, the Escrow
    Agent shall receive fees in the amounts specified inSchedule
    Cto this Agreement and shall be reimbursed
    upon request for all reasonable expenses, disbursements and advances, including
    reasonable fees of outside counsel, if any, reasonably incurred or made by
    it in connection with the preparation of this Agreement and the carrying
    out of its duties under this Agreement. All such fees and expenses shall
    be paid by SCA.

Sch. 1.01(d)-4

(g)SCA
    shall reimburse and indemnify the Escrow Agent for, and hold it harmless
    against, any loss, liability or expense, including, without limitation, reasonable
    attorneys’ fees, incurred without gross negligence or willful misconduct
    on the part of the Escrow Agent arising out of, or connection with the acceptance
    of, or the performance of, its duties and obligations under this Agreement.

(h)The
    Escrow Agent may at any time resign by giving 30 days’ prior written
    notice of resignation to SCA and XLCA. SCA and XLCA (with the consent of
    the Required Consenting CDS Counterparties) may at any time jointly remove
    the Escrow Agent by giving 10 Business Days’ written notice to the
    Escrow Agent signed by the Secretaries of SCA and XLCA stating that the Required
    Consenting CDS Counterparties have consented to such removal. If the Escrow
    Agent shall resign or be removed, a successor Escrow Agent (the “Successor
    Escrow Agent”), shall be appointed jointly
    by XLCA and SCA (with the consent of the Required Consenting CDS Counterparties)
    by written instrument executed by the Secretaries of SCA and XLCA stating
    that the Required Consenting CDS Counterparties have consented to such removal.
    Such written instrument shall be delivered to the Escrow Agent (the “Predecessor
    Escrow Agent”) and to the Successor Escrow
    Agent and, thereupon, the resignation or removal of the Predecessor Escrow
    Agent shall become effective and the Successor Escrow Agent, without any
    further act, deed or conveyance, shall become vested with all right, title
    and interest to all cash and property held hereunder of the Predecessor Escrow
    Agent, and the Predecessor Escrow Agent shall, on the written request of
    the XLCA and SCA or the Successor Escrow Agent, execute and deliver to the
    Successor Escrow Agent all the right, title and interest hereunder in and
    to the Escrow Property held by the Predecessor Escrow Agent and all other
    rights hereunder, and records relating hereto, of the Predecessor Escrow
    Agent. If no successor Escrow Agent shall have been appointed within 20 Business
    Days of a notice of resignation or removal by the Escrow Agent, the Escrow
    Agent may apply to a court of competent jurisdiction for appointment of a
    Successor Escrow Agent.

(i)If
    any controversy arises between the other parties to this Agreement concerning
    the subject matter of this Agreement, its terms or conditions, the Escrow
    Agent will not be required to determine the controversy or to take any action
    regarding it. The Escrow Agent may continue to hold the Escrow Property and
    all documents, assets and funds relating to the Escrow Property and may wait
    for settlement of any such controversy by final appropriate legal proceedings
    or other means. In such event, the Escrow Agent will not be liable for interest
    or damage. Furthermore, the Escrow Agent may, at its option, file an action
    of interpleader requiring the parties other than the Escrow Agent to answer
    and litigate any claims and rights among themselves. The Escrow Agent is
    authorized, at its option, to deposit with the clerk of the court or the
    arbitrator, as applicable, all documents and funds held in escrow, except
    all costs, expenses, charges and reasonable attorneys’ fees incurred
    by the Escrow Agent due to the interpleader action and which the other parties
    to this Agreement agree to pay or are ordered to pay by such court or arbitrator.
    Upon initiating such interpleader action, the Escrow Agent shall be fully
    released and discharged of and from all obligations and liability imposed
    by the terms of this Agreement.
