    GENERAL
      PROVISIONS

    

    I. PURPOSE
      OF THE PLAN

    

    This
      2006
      Stock Incentive Plan is intended to promote the interests of Positron
      Corporation (the "Corporation") by providing eligible persons with the
      opportunity to acquire a proprietary interest, or otherwise increase their
      proprietary interest, in the Corporation as an incentive for them to remain
      in
      the Service of the Corporation.

    

    Capitalized
      terms shall have the meanings assigned to such terms in the attached
      Appendix.

    

    II. STRUCTURE
      OF THE PLAN

    

    A. The
      Plan
      shall be divided into two separate equity programs:

    

    
      	
            	-	
              the
                Discretionary Option Grant Program under which eligible persons may,
                at
                the discretion of the Plan Administrator, be granted options to purchase
                shares of Common Stock and stock appreciation rights;
                and

            

    

    

    
      	
            	-	
              the
                Stock Issuance Program under which eligible persons may, at the discretion
                of the Plan Administrator, be issued shares of Common Stock directly,
                either through the immediate purchase of such shares or as a bonus
                for
                services rendered the Corporation (or any Parent or
                Subsidiary).

            

    

    

    B. The
      provisions of Articles One and Four shall apply to all equity programs under
      the
      Plan and shall govern the interests of all persons under the Plan.

    

    III. ADMINISTRATION
      OF THE PLAN

    

    A. The
      Plan
      shall be administered by the Board or an Option Committee appointed by the
      Board. Should administration of the Plan be vested in an Option Committee,
      any
      discretionary option grants or stock issuances to members of the Option
      Committee must be authorized and approved by a disinterested majority of the
      Board.

    

    B. Members
      of the Option Committee shall serve for such period of time as the Board may
      determine and may be removed by the Board at any time.

    

    C. Each
      Plan
      Administrator shall, within the scope of its administrative functions under
      the
      Plan, have full power and authority (subject to the provisions of the Plan)
      to
      establish such rules and regulations as it may deem appropriate for proper
      administration of the Discretionary Option Grant and Stock Issuance Programs
      and
      to make such determinations under, and issue such interpretations of, the
      provisions of such programs and any outstanding options or stock issuances
      thereunder as it may deem necessary or advisable. Decisions of the Plan
      Administrator within the scope of its administrative functions under the Plan
      shall be final and binding on all parties who have an interest in the
      Discretionary Option Grant and Stock Issuance Programs under its jurisdiction
      or
      any option or stock issuance thereunder.

    

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    D. Service
      on the Option Committee shall constitute service as a Board member, and members
      of such committee shall accordingly be entitled to full indemnification and
      reimbursement as Board members for their service on such committee. No member
      of
      the Option Committee shall be liable for any act or omission made in good faith
      with respect to the Plan or any option grants or stock issuances under the
      Plan.

    

    IV. ELIGIBILITY

    

    A. The
      persons eligible to participate in the Discretionary Option Grant and Stock
      Issuance Programs are as follows:

    

    (i) Employees,

    

    (ii) Officers,
      members of the Board or the board of directors of any Parent or Subsidiary,
      and

    

    (iii) consultants
      and other independent advisors who provide services to the Corporation (or
      any
      Parent or Subsidiary).

    

    B. Each
      Plan
      Administrator shall, within the scope of its administrative jurisdiction under
      the Plan, have full authority to determine: (i) with respect to the option
      grants or stock appreciation rights under the Discretionary Option Grant
      Program, which eligible persons are to receive grants, the time or times when
      such grants are to be made, the number of shares to be covered by each such
      grant, the time or times when each option is to become exercisable, the vesting
      schedule (if any) applicable to the option shares and the maximum term for
      which
      the option is to remain outstanding; and (ii) with respect to stock issuances
      under the Stock Issuance Program, which eligible persons are to receive stock
      issuances, the time or times when such issuances are to be made, the number
      of
      shares to be issued to each Participant, the vesting schedule (if any)
      applicable to the issued shares and the consideration for such
      shares.

    

    C. The
      Plan
      Administrator shall have the absolute discretion either to grant options or
      stock appreciation rights in accordance with the Discretionary Option Grant
      Program or to effect stock issuances or grant share right awards in accordance
      with the Stock Issuance Program.

    

    V. STOCK
      SUBJECT TO THE PLAN

    

    A. The
      stock
      issuable under the Plan shall be shares of authorized but unissued or reacquired
      Common Stock, including shares repurchased by the Corporation on the open
      market. The maximum number of shares of Common Stock initially reserved for
      issuance over the term of the Plan shall not exceed five million
      (5,000,000) shares. 

    

    B. Shares
      of
      Common Stock subject to outstanding options shall be available for subsequent
      issuance under the Plan to the extent (i) those options expire or terminate
      for
      any reason prior to exercise in full or (ii) the options are canceled in
      accordance with the cancellation-regrant provisions of Article Two. Unvested
      shares issued under the Plan and subsequently canceled or repurchased by the
      Corporation at the original exercise or issue price paid per share, pursuant
      to
      the Corporation's repurchase rights under the Plan, shall be added back to
      the
      number of shares of Common Stock reserved for issuance under the Plan and shall
      accordingly be available for reissuance through one or more subsequent option
      grants or direct stock issuances under the Plan. In addition, should the
      exercise price of an option under the Plan be paid with shares of Common Stock
      or should shares of Common Stock otherwise issuable under the Plan be withheld
      by the Corporation in satisfaction of the withholding taxes incurred in
      connection with the exercise of an option or the vesting of a stock issuance
      under the Plan, then the number of shares of Common Stock available for issuance
      under the Plan shall be reduced only by the net number of shares of Common
      Stock
      issued to the holder of such option or stock issuance, and not by the gross
      number of shares for which the option is exercised or which vest under the
      stock
      issuance. However, shares of Common Stock underlying one or more stock
      appreciation rights exercised under Section V of Article Two of the Plan shall
      not be available for subsequent issuance under the Plan.

    

    
      
        
        

      

      
        -2-

        
          

        

      

      
        
        

      

    

    C. If
      any
      change is made to the Common Stock by reason of any stock split, stock dividend,
      recapitalization, combination of shares, exchange of shares or other change
      affecting the outstanding Common Stock as a class without the Corporation's
      receipt of consideration, appropriate adjustments shall be made to: (i) the
      maximum number and/or class of securities issuable under the Plan; and (ii)
      the
      number and/or class of securities and the exercise price per share in effect
      under each outstanding option under the Plan. Such adjustments to the
      outstanding options are to be effected in a manner which shall preclude the
      enlargement or dilution of rights and benefits under such options. The
      adjustments determined by the Plan Administrator shall be final, binding and
      conclusive.

    DISCRETIONARY
      OPTION GRANT PROGRAM

    

    I. OPTION
      TERMS

    

    Each
      option shall be evidenced by one or more documents in the form approved by
      the
      Plan Administrator; provided, however, that each such document shall comply
      with
      the terms specified below. 

    

    A. EXERCISE
      PRICE.

    

    1. The
      exercise price per share shall be fixed by the Plan Administrator.

    

    2. The
      exercise price shall become immediately due upon exercise of the option and
      may,
      subject to the provisions of Section I of Article Four and the documents
      evidencing the option, be payable in one or more of the forms specified
      below:

    

    (i) cash
      or
      check made payable to the Corporation, or

    

    (ii) shares
      of
      Common Stock held for the requisite period necessary to avoid a charge to the
      Corporation's earnings for financial reporting purposes and valued at Fair
      Market Value on the Exercise Date, or

    

    (iii) to
      the
      extent the sale complies with all applicable laws relating to the regulation
      and
      sale of securities, through a special sale and remittance procedure pursuant
      to
      which the Optionee shall concurrently provide irrevocable written instructions
      to: (a) a Corporation-designated brokerage firm to effect the immediate sale
      of
      the purchased shares and remit to the Corporation, out of the sale proceeds
      available on the settlement date, sufficient funds to cover the aggregate
      exercise price payable for the purchased shares plus all applicable Federal,
      state and local income and employment taxes required to be withheld by the
      Corporation by reason of such exercise; and (b) the Corporation to deliver
      the
      certificates for the purchased shares directly to such brokerage firm in order
      to complete the sale, or

    

    
      
        
        

      

      
        -3-

        
          

        

      

      
        
        

      

    

    (iv) subject
      to such additional terms and conditions as the plan administrator shall
      determine, to have the number of shares deliverable to the option holder as
      a
      result of the exercise reduced by a number of shares sufficient to pay the
      amount the Corporation determines to be necessary to withhold for federal,
      state, local and other taxes as a result of the exercise of the option and,
      as
      long as no additional accounting expenses would result to the Corporation,
      to
      pay the exercise price of the option.

    

    Except
      to
      the extent such sale and remittance procedure is utilized, payment of the
      exercise price for the purchased shares must be made on the Exercise
      Date.

    

    B. EXERCISE
      AND TERM OF OPTIONS. Each option shall be exercisable at such time or times,
      during such period and for such number of shares as shall be determined by
      the
      Plan Administrator and set forth in the documents evidencing the option.
      However, no option shall have a term in excess of ten (10) years measured from
      the option grant date.

    

    C. EFFECT
      OF
      TERMINATION OF SERVICE.

    

    1. The
      following provisions shall govern the exercise of any options held by the
      Optionee at the time of cessation of Service or death:

    

    (i) Subject
      to subparagraph (iv) below, any option outstanding at the time of the
      Optionee's cessation of Service for any reason shall remain exercisable for
      such
      period of time thereafter as shall be determined by the Plan Administrator
      and
      set forth in the documents evidencing the option.

    

    (ii) Any
      option held by the Optionee at the time of death and exercisable in whole or
      in
      part at that time may be subsequently exercised by the personal representative
      of the Optionee's estate or by the person or persons to whom the option is
      transferred pursuant to the Optionee's will or in accordance with the laws
      of
      descent and distribution or by the Optionee's designated beneficiary or
      beneficiaries of that option.

    

    (iii) Except
      as
      otherwise determined in the discretion of the Plan Administrator either at
      the
      time the option is granted or at any time the option remains outstanding, should
      the Optionee's Service be terminated for Misconduct or should the Optionee
      otherwise engage in Misconduct while one or more options granted to the Optionee
      under this Article Two are outstanding, then all those options shall terminate
      immediately and cease to be outstanding.

    

    (iv) During
      the applicable post-Service exercise period, the option may not be exercised
      in
      the aggregate for more than the number of vested shares for which the option
      is
      exercisable on the date of the Optionee's cessation of Service. Upon the
      expiration of the applicable exercise period or (if earlier) upon the expiration
      of the option term, the option shall terminate and cease to be outstanding
      for
      any vested shares for which the option has not been exercised. However, the
      option shall, immediately upon the Optionee's cessation of Service, terminate
      and cease to be outstanding to the extent the option is not otherwise at that
      time exercisable for vested shares.

    

    
      
        
        

      

      
        -4-

        
          

        

      

      
        
        

      

    

    2. The
      Plan
      Administrator shall have complete discretion, either at the time an option
      is
      granted or at any time while the option remains outstanding, to:

    

    (i) extend
      the period of time for which the option is to remain exercisable following
      the
      Optionee's cessation of Service from the limited exercise period otherwise
      in
      effect for that option to such greater period of time as the Plan Administrator
      shall deem appropriate, but in no event beyond the expiration of the option
      term, and/or

    

    (ii) permit
      the option to be exercised, during the applicable post-Service exercise period,
      not only with respect to the number of vested shares of Common Stock for which
      such option is exercisable at the time of the Optionee's cessation of Service
      but also with respect to one or more additional installments in which the
      Optionee would have vested had the Optionee continued in Service.

    

    D. STOCKHOLDER
      RIGHTS. The holder of an option shall have no stockholder rights with respect
      to
      the shares subject to the option until such person shall have exercised the
      option, paid the exercise price and become a holder of record of the purchased
      shares.

    

    E. REPURCHASE
      RIGHTS. The Plan Administrator shall have the discretion to grant options which
      are exercisable for unvested shares of Common Stock. Should the Optionee cease
      Service while holding such unvested shares, the Corporation shall have the
      right
      to repurchase, at the purchase price paid per share, any or all of those
      unvested shares. The terms upon which such repurchase right shall be exercisable
      (including the period and procedure for exercise and the appropriate vesting
      schedule for the purchased shares) shall be established by the Plan
      Administrator and set forth in the document evidencing such repurchase
      right.

    

    F. LIMITED
      TRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee, the options
      shall be exercisable only by the Optionee and shall not be assignable or
      transferable other than by will or by the laws of descent and distribution
      following the Optionee's death, provided
      however,
      that an
      option may be assigned in whole or in part during Optionee's lifetime to one
      or
      more members of the Optionee's Immediate Family or to a trust established for
      the exclusive benefit of Optionee or one or more members of the Optionee's
      Immediate Family or to the Optionee's former spouse, to the extent such
      assignment is in connection with Optionee's estate plan or pursuant to a
      domestic relations order. The assigned portion shall be exercisable only by
      the
      person or persons who acquire a proprietary interest in the option pursuant
      to
      such assignment. The terms applicable to the assigned portion shall be the
      same
      as those in effect for this option immediately prior to such assignment and
      shall be set forth in such documents issued to the assignee as the Plan
      Administrator may deem appropriate. Notwithstanding the foregoing, the Optionee
      may also designate one or more persons as the beneficiary or beneficiaries
      of
      his or her outstanding options under this Article Two, and those options shall,
      in accordance with such designation, automatically be transferred to such
      beneficiary or beneficiaries upon the Optionee's death while holding those
      options. Such beneficiary or beneficiaries shall take the transferred option
      subject to all the terms and conditions of the applicable agreement evidencing
      each such transferred option, including (without limitation) the limited time
      period during which the option may be exercised following the Optionee's
      death.

    

    II. CANCELLATION
      AND REGRANT OF OPTIONS

    

    The
      Plan
      Administrator shall have the authority to effect, at any time and from time
      to
      time, with the consent of the affected option holders, the cancellation of
      any
      or all outstanding options under the Discretionary Option Grant Program and
      to
      grant in substitution new options covering the same or different number of
      shares of Common Stock but with an exercise price per share based on the Fair
      Market Value per share of Common Stock on the new grant date.

    

    
      
        
        

      

      
        -5-

        
          

        

      

      
        
        

      

    

    III. CHANGE
      IN
      CONTROL/HOSTILE TAKE-OVER

    

    A. No
      option
      outstanding at the time of a Change in Control shall become exercisable on
      an
      accelerated basis if and to the extent: (i) that option is, in connection with
      the Change in Control, assumed by the successor corporation (or parent thereof)
      or otherwise continued in full force and effect pursuant to the terms of the
      Change in Control transaction, (ii) such option is replaced with a cash
      incentive program of the successor corporation which preserves the spread
      existing at the time of the Change in Control on the shares of Common Stock
      for
      which the option is not otherwise at that time exercisable and provides for
      subsequent payout in accordance with the same exercise/vesting schedule
      applicable to those option shares or (iii) the acceleration of such option
      is
      subject to other limitations imposed by the Plan Administrator at the time
      of
      the option grant. However, if none of the foregoing conditions are satisfied,
      then each option outstanding at the time of the Change in Control but not
      otherwise exercisable for all the shares of Common Stock at that time subject
      to
      such option shall automatically accelerate so that each such option shall,
      immediately prior to the effective date of the Change in Control, become
      exercisable for all the shares of Common Stock at the time subject to such
      option and may be exercised for any or all of those shares as fully vested
      shares of Common Stock.

    

    B. All
      of
      the Corporation's outstanding repurchase rights under the Discretionary Option
      Grant Program shall also terminate automatically, and the shares of Common
      Stock
      subject to those terminated rights shall immediately vest in full, in the event
      of any Change in Control, except to the extent: (i) those repurchase rights
      are
      assigned to the successor corporation (or parent thereof) or otherwise continued
      in full force and effect pursuant to the terms of the Change in Control
      transaction or (ii) such accelerated vesting is precluded by other limitations
      imposed by the Plan Administrator at the time the repurchase right is
      issued.

    

    C. Immediately
      following the consummation of the Change in Control, all outstanding options
      shall terminate and cease to be outstanding, except to the extent assumed by
      the
      successor corporation (or parent thereof) or otherwise expressly continued
      in
      full force and effect pursuant to the terms of the Change in Control
      transaction.

    

    D. Each
      option which is assumed in connection with a Change in Control or otherwise
      continued in effect shall be appropriately adjusted, immediately after such
      Change in Control, to apply to the number and class of securities which would
      have been issuable to the Optionee in consummation of such Change in Control
      had
      the option been exercised immediately prior to such Change in Control.
      Appropriate adjustments to reflect such Change in Control shall also be made
      to:
      (i) the exercise price payable per share under each outstanding option, provided
      the aggregate exercise price payable for such securities shall remain the same;
      (ii) the maximum number and/or class of securities available for issuance over
      the remaining term of the Plan; and (iii) the maximum number and/or class of
      securities for which any one person may be granted options, direct stock
      issuances and share right awards under the Plan per calendar year. To the extent
      the actual holders of the Corporation's outstanding Common Stock receive cash
      consideration for their Common Stock in consummation of the Change in Control
      transaction, the successor corporation may, in connection with the assumption
      of
      the outstanding options under the Discretionary Option Grant Program, substitute
      one or more shares of its own common stock with a fair market value equivalent
      to the cash consideration paid per share of Common Stock in such Change in
      Control transaction.

    

    
      
        
        

      

      
        -6-

        
          

        

      

      
        
        

      

    

    E. The
      Plan
      Administrator shall have the discretionary authority to structure one or more
      outstanding options under the Discretionary Option Grant Program so that those
      options shall, immediately prior to the effective date of a Change in Control,
      become exercisable for all the shares of Common Stock at that time subject
      to
      such options on an accelerated basis and may be exercised for any or all of
      such
      shares as fully vested shares of Common Stock, whether or not those options
      are
      to be assumed or otherwise continued in full force and effect or replaced with
      a
      cash incentive program pursuant to the express terms of the Change in Control
      transaction. In addition, the Plan Administrator shall have the discretionary
      authority to structure one or more of the Corporation's repurchase rights under
      the Discretionary Option Grant Program so that those rights shall immediately
      terminate at the time of such Change in Control and shall not be assignable
      to
      the successor corporation (or parent thereof), and the shares subject to those
      terminated rights shall accordingly vest in full at the time of such Change
      in
      Control.

    

    F. The
      Plan
      Administrator shall have full power and authority to structure one or more
      outstanding options under the Discretionary Option Grant Program so that those
      options shall vest and become exercisable for all the shares of Common Stock
      at
      that time subject to such options on an accelerated basis in the event the
      Optionee's Service is subsequently terminated by reason of an Involuntary
      Termination within a designated period (not to exceed eighteen (18) months)
      following the effective date of any Change in Control in which those options
      do
      not otherwise accelerate. Any options so accelerated shall remain exercisable
      for fully vested shares of Common Stock until the expiration or sooner
      termination of the option term. In addition, the Plan Administrator may
      structure one or more of the Corporation's repurchase rights under the
      Discretionary Option Grant Program so that those rights shall immediately
      terminate with respect to any shares of Common Stock held by the Optionee at
      the
      time of his or her Involuntary Termination, and the shares subject to those
      terminated repurchase rights shall accordingly vest in full at that
      time.

    

    G. The
      Plan
      Administrator shall have the discretionary authority to structure one or more
      outstanding options under the Discretionary Option Grant Program so that those
      options shall, immediately prior to the effective date of a Hostile Take-Over,
      vest and become exercisable for all the shares of Common Stock at that time
      subject to such options on an accelerated basis and may be exercised for any
      or
      all of such shares as fully vested shares of Common Stock. In addition, the
      Plan
      Administrator shall have the discretionary authority to structure one or more
      of
      the Corporation's repurchase rights under the Discretionary Option Grant Program
      so that those rights shall terminate automatically upon the consummation of
      such
      Hostile Take-Over, and the shares subject to those terminated rights shall
      thereupon immediately vest in full. Alternatively, the Plan Administrator may
      condition the automatic acceleration of one or more outstanding options under
      the Discretionary Option Grant Program and the termination of one or more of
      the
      Corporation's outstanding repurchase rights under such program upon the
      Involuntary Termination of the Optionee's Service within a designated period
      (not to exceed eighteen (18) months) following the effective date of such
      Hostile Take-Over. Each option so accelerated shall remain exercisable for
      fully
      vested shares of Common Stock until the expiration or sooner termination of
      the
      option term.

    

    H. The
      grant
      of options under the Discretionary Option Grant Program shall in no way affect
      the right of the Corporation to adjust, reclassify, reorganize or otherwise
      change its capital or business structure or to merge, consolidate, dissolve,
      liquidate or sell or transfer all or any part of its business or
      assets.

    

    V. STOCK
      APPRECIATION RIGHTS

    

    The
      Plan
      Administrator may, subject to such conditions as it may determine, grant to
      selected Optionees stock appreciation rights which will allow the holders of
      those rights to elect between the exercise of the underlying option for shares
      of Common Stock and the surrender of that option in exchange for a distribution
      from the Corporation in an amount equal to the excess of: (A) the Option
      Surrender Value of the number of shares for which the option is surrendered;
      over (B) the aggregate exercise price payable for such shares. The distribution
      may be made in shares of Common Stock valued at Fair Market Value on the option
      surrender date, in cash, or partly in shares and partly in cash, as the Plan
      Administrator shall in its sole discretion deem appropriate.

    STOCK
      ISSUANCE PROGRAM

    

    I. STOCK
      ISSUANCES

    

    Shares
      of
      Common Stock may be issued under the Stock Issuance Program through direct
      and
      immediate issuances without any intervening option grants. Each such stock
      issuance shall be evidenced by a Stock Issuance Agreement which complies with
      the terms specified below. Shares of Common Stock may also be issued under
      the
      Stock Issuance Program pursuant to share right awards which entitle the
      recipients to receive those shares upon the attainment of designated performance
      goals. 

    

    II. STOCK
      ISSUANCE TERMS

    

    A. PURCHASE
      PRICE.

    

    1. The
      purchase price per share shall be fixed by the Plan Administrator.

    

    2. Subject
      to the provisions of Section I of Article Four, shares of Common Stock may
      be
      issued under the Stock Issuance Program for any of the following items of
      consideration which the Plan Administrator may deem appropriate in each
      individual instance:

    

    (i) cash
      or
      check made payable to the Corporation, or

    

    (ii) services
      rendered or to be rendered to the Corporation (or any Parent or
      Subsidiary).

    

    B. VESTING
      PROVISIONS.

    

    1. Shares
      of
      Common Stock issued under the Stock Issuance Program may, in the discretion
      of
      the Plan Administrator, be fully and immediately vested upon issuance or may
      vest in one or more installments over the Participant's period of Service or
      upon attainment of specified performance objectives. The elements of the vesting
      schedule applicable to any unvested shares of Common Stock issued under the
      Stock Issuance Program shall be determined by the Plan Administrator and
      incorporated into the Stock Issuance Agreement. Shares of Common Stock may
      also
      be issued under the Stock Issuance Program pursuant to share right awards which
      entitle the recipients to receive those shares upon the attainment of designated
      performance goals. Upon the attainment of such performance goals, fully vested
      shares of Common Stock shall be issued upon satisfaction of those share right
      awards.

    

    2. Any
      new,
      substituted or additional securities or other property (including money paid
      other than as a regular cash dividend) which the Participant may have the right
      to receive with respect to the Participant's unvested shares of Common Stock
      by
      reason of any stock dividend, stock split, recapitalization, combination of
      shares, exchange of shares or other change affecting the outstanding Common
      Stock as a class without the Corporation's receipt of consideration shall be
      issued subject to: (i) the same vesting requirements applicable to the
      Participant's unvested shares of Common Stock; and (ii) such escrow arrangements
      as the Plan Administrator shall deem appropriate.

    

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

    3. The
      Participant shall have full stockholder rights with respect to any shares of
      Common Stock issued to the Participant under the Stock Issuance Program, whether
      or not the Participant's interest in those shares is vested. Accordingly, the
      Participant shall have the right to vote such shares and to receive any regular
      cash dividends paid on such shares.

    

    4. Should
      the Participant cease to remain in Service while holding one or more unvested
      shares of Common Stock issued under the Stock Issuance Program or should the
      performance objectives not be attained with respect to one or more such unvested
      shares of Common Stock, then those shares shall be immediately surrendered
      to
      the Corporation for cancellation, and the Participant shall have no further
      stockholder rights with respect to those shares. To the extent the surrendered
      shares were previously issued to the Participant for consideration paid in
      cash
      or cash equivalent (including the Participant's purchase-money indebtedness
      but
      not including services rendered by the Participant), the Corporation shall
      repay
      to the Participant the cash consideration paid for the surrendered shares and
      shall cancel the unpaid principal balance of any outstanding purchase-money
      note
      of the Participant attributable to the surrendered shares.

    

    5. The
      Plan
      Administrator may in its discretion waive the surrender and cancellation of
      one
      or more unvested shares of Common Stock which would otherwise occur upon the
      cessation of the Participant's Service or the non-attainment of the performance
      objectives applicable to those shares. Such waiver shall result in the immediate
      vesting of the Participant's interest in the shares as to which the waiver
      applies. Such waiver may be effected at any time, whether before or after the
      Participant's cessation of Service or the attainment or non-attainment of the
      applicable performance objectives.

    

    6. Outstanding
      share right awards under the Stock Issuance Program shall automatically
      terminate, and no shares of Common Stock shall actually be issued in
      satisfaction of those awards, if the performance goals or Service requirements
      established for such awards are not attained. The Plan Administrator, however,
      shall have the discretionary authority to issue shares of Common Stock under
      one
      or more outstanding share right awards as to which the designated performance
      goals or Service requirements have not been attained.

    

    III. CHANGE
      IN
      CONTROL/HOSTILE TAKE-OVER

    

    A. All
      of
      the Corporation's outstanding repurchase rights under the Stock Issuance Program
      shall terminate automatically, and all the shares of Common Stock subject to
      those terminated rights shall immediately vest in full, in the event of any
      Change in Control, except to the extent (i) those repurchase rights are assigned
      to the successor corporation (or parent thereof) or otherwise continued in
      full
      force and effect pursuant to the express terms of the Change in Control
      transaction or (ii) such accelerated vesting is precluded by other limitations
      imposed in the Stock Issuance Agreement.

    

    B. The
      Plan
      Administrator shall have the discretionary authority to structure one or more
      of
      the Corporation's repurchase rights under the Stock Issuance Program so that
      those rights shall automatically terminate in whole or in part upon the
      occurrence of a Change in Control and shall not be assignable to the successor
      corporation (or parent thereof), and the shares of Common Stock subject to
      those
      terminated rights shall immediately vest in full at the time of such Change
      in
      Control.

    C. The
      Plan
      Administrator shall also have the discretionary authority to structure one
      or
      more of the Corporation's repurchase rights under the Stock Issuance Program
      so
      that those rights shall automatically terminate in whole or in part, and the
      shares of Common Stock subject to those terminated rights shall immediately
      vest
      in full, upon the Involuntary Termination of the Participant's Service within
      a
      designated period (not to exceed eighteen (18) months) following the effective
      date of any Change in Control in which those repurchase rights do not otherwise
      terminate. 

    

    D. The
      Plan
      Administrator shall also have the discretionary authority to structure one
      or
      more of the Corporation's repurchase rights under the Stock Issuance Program
      so
      that those rights shall automatically terminate in whole or in part upon the
      occurrence of a Hostile Take-Over, and the shares of Common Stock subject to
      those terminated rights shall immediately vest in full at the time of such
      Hostile Take-Over.

    MISCELLANEOUS

    

    I. FINANCING

    

    The
      Plan
      Administrator may permit any Optionee or Participant to pay the option exercise
      price under the Discretionary Option Grant Program or the purchase price of
      shares issued under the Stock Issuance Program by delivering a full-recourse,
      interest bearing promissory note payable in one or more installments. The terms
      of any such promissory note (including the interest rate and the terms of
      repayment) shall be established by the Plan Administrator in its sole
      discretion. In no event may the maximum credit available to the Optionee or
      Participant exceed the sum of (i) the aggregate option exercise price or
      purchase price payable for the purchased shares plus (ii) any Federal, state
      and
      local income and employment tax liability incurred by the Optionee or the
      Participant in connection with the option exercise or share
      purchase.

    

    II. SHARE
      ESCROW/LEGENDS

    

    Unvested
      shares issued under the Plan may, in the Plan Administrator's discretion, be
      held in escrow by the Corporation until the Participant's interest in such
      shares vests or may be issued directly to the Participant with restrictive
      legends on the certificates evidencing those unvested shares.

    

    III. TAX
      WITHHOLDING

    

    A. The
      Corporation's obligation to deliver shares of Common Stock upon the exercise
      of
      options or the issuance or vesting of such shares under the Plan shall be
      subject to the satisfaction of all applicable Federal, state and local income
      and employment tax withholding requirements.

    

    B. The
      Plan
      Administrator may, in its discretion, provide any or all holders of options
      or
      unvested shares of Common Stock under the Plan with the right to use shares
      of
      Common Stock in satisfaction of all or part of the Taxes incurred by such
      holders in connection with the exercise of their options or the vesting of
      their
      shares. Such right may be provided to any such holder in either or both of
      the
      following formats:

    

    1. Stock
      Withholding: The election to have the Corporation withhold, from the shares
      of
      Common Stock otherwise issuable upon the exercise of such option or the vesting
      of such shares, a portion of those shares with an aggregate Fair Market Value
      equal to the amount of the Taxes (not to exceed one hundred percent (100%)
      of
      such Taxes) to be satisfied in such manner as designated by the holder in
      writing; or

    

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

    2. Stock
      Delivery: The election to deliver to the Corporation, at the time the option
      is
      exercised or the shares vest, one or more shares of Common Stock previously
      acquired by such holder (other than in connection with the option exercise
      or
      share vesting triggering the Taxes) with an aggregate Fair Market Value equal
      to
      the amount of the Taxes (not to exceed one hundred percent (100%) of such Taxes)
      to be satisfied in such manner as designated by the holder in
      writing.

    

    IV. EFFECTIVE
      DATE AND TERM OF THE PLAN

    

    A. The
      Plan
      shall become effective immediately upon the Plan Effective Date. Options may
      be
      granted under the Discretionary Option Grant at any time on or after the Plan
      Effective Date.

    

    B. The
      Plan
      shall terminate upon the EARLIEST of (i) the tenth anniversary of the Plan
      Effective Date, (ii) the date on which all shares available for issuance under
      the Plan shall have been issued as fully-vested shares or (iii) the termination
      of all outstanding options in connection with a Change in Control. Upon such
      plan termination, all outstanding option grants and unvested stock issuances
      shall thereafter continue to have force and effect in accordance with the
      provisions of the documents evidencing such grants or issuances.

    

    V. AMENDMENT
      OF THE PLAN

    

    A. The
      Board
      shall have complete and exclusive power and authority to amend or modify the
      Plan in any or all respects. However, no such amendment or modification shall
      adversely affect the rights and obligations with respect to stock options or
      unvested stock issuances at the time outstanding under the Plan unless the
      Optionee or the Participant consents to such amendment or modification. In
      addition, certain amendments may require stockholder approval pursuant to
      applicable laws or regulations.

    

    B. Options
      to purchase shares of Common Stock may be granted under the Discretionary Option
      Grant Program and shares of Common Stock may be issued under the Stock Issuance
      Program that are in each instance in excess of the number of shares then
      available for issuance under the Plan, provided any excess shares actually
      issued under those programs shall be held in escrow until there is obtained
      any
      required approval of an amendment sufficiently increasing the number of shares
      of Common Stock available for issuance under the Plan. If such approval is
      not
      obtained within twelve (12) months after the date the first such excess
      issuances are made, then (i) any unexercised options granted on the basis of
      such excess shares shall terminate and cease to be outstanding and (ii) the
      Corporation shall promptly refund to the Optionees and the Participants the
      exercise or purchase price paid for any excess shares issued under the Plan
      and
      held in escrow, together with interest (at the applicable Short Term Federal
      Rate) for the period the shares were held in escrow, and such shares shall
      thereupon be automatically canceled and cease to be outstanding.

    

    VI. USE
      OF
      PROCEEDS

    

    Any
      cash
      proceeds received by the Corporation from the sale of shares of Common Stock
      under the Plan shall be used for general corporate purposes.

    VII. REGULATORY
      APPROVALS

    

    A. The
      implementation of the Plan, the granting of any stock option under the Plan
      and
      the issuance of any shares of Common Stock (i) upon the exercise of any granted
      option or (ii) under the Stock Issuance Program shall be subject to the
      Corporation's procurement of all approvals and permits required by regulatory
      authorities having jurisdiction over the Plan, the stock options granted under
      it and the shares of Common Stock issued pursuant to it.

    

    B. No
      shares
      of Common Stock or other assets shall be issued or delivered under the Plan
      unless and until there shall have been compliance with all applicable
      requirements of Federal and state securities laws, including the filing and
      effectiveness of the Form S-8 registration statement for the shares of Common
      Stock issuable under the Plan, and all applicable listing requirements of the
      stock exchange or automated quotation system, as applicable, on which Common
      Stock is then quoted for trading.

    

    VIII. NO
      EMPLOYMENT/SERVICE RIGHTS

    

    Nothing
      in the Plan shall confer upon the Optionee or the Participant any right to
      continue in Service for any period of specific duration or interfere with or
      otherwise restrict in any way the rights of the Corporation (or any Parent
      or
      Subsidiary employing or retaining such person) or of the Optionee or the
      Participant, which rights are hereby expressly reserved by each, to terminate
      such person's Service at any time for any reason, with or without
      cause.

    provided,
      however, the Plan Administrator shall have the discretionary authority to

                the closing
                selling price per
                share of Common Stock on the date in question shall be used, as such
                price
                is reported by the National Association of Securities Dealers on
                the

                closing
                selling price per
                share of Common Stock on the date in question on the stock exchange
                determined by the Plan Administrator to be the primary market for
                the
                Common Stock shall be used, as such price is officially quoted in

                but

                be

      and Servicing Agreement and the Mortgage Loan Purchase Agreement with respect
      to
      the Mortgage Loans (including the Issuer’s right to cause the Seller to
      repurchase Mortgage Loans from the Issuer under certain circumstances described
      therein); (iii) all present and future claims, demands, causes of action and
      choses in action in respect of any or all of the foregoing and all payments
      on
      or under and all proceeds of every kind and nature whatsoever in respect of
      any

      the
      foregoing; (iv) the Collection Account, the Distribution Account and all funds
      and other property on deposit from time to time therein; (v) all other money,
      investments, investment property, accounts, general intangibles and other
      property of the Trust from time to time; and (vi) any and all proceeds of the
      foregoing (collectively the “Collateral”).

     

    The
      foregoing Grant is made in trust to secure the payment of principal of and

      perform its duties required in this Indenture to the best of its ability to
      the
      end that the interests of the holders of the Notes and the Insurer may be
      adequately and effectively protected. The Indenture Trustee further agrees
      and
      acknowledges that the documents listed in Section 2.01(b) of the Sale and
      Servicing Agreement for each Mortgage Loan will be held initially by the Seller
      as custodian and bailee and that each item of Collateral
      that is physically delivered to the Indenture Trustee will be held by the
      Indenture
      Trustee
      in the State of New York and/or the State of California.

        thereto and any other reasonable expenses (including the fees and expenses
        of
        the Indenture Trustee) connected therewith.

       

      Every
        replacement Class A Note issued pursuant to this Section 2.4 in replacement
        of
        any mutilated, destroyed, lost or stolen Class A Note shall constitute an
        original additional contractual obligation of the Issuer, whether or not
        the
        mutilated, destroyed, lost or stolen Class A Note shall be at any time
        enforceable by anyone, and shall be entitled to all the benefits of this
        Indenture equally and proportionately with any and all other Class A Notes
        duly
        issued hereunder.

       

      The
        provisions of this Section 2.4 are exclusive and shall preclude (to the extent
        lawful) all other rights and remedies with respect to the replacement or
        payment
        of mutilated, destroyed, lost or stolen Class A Notes.

        to it;
        provided, that such Issuer
        Order is
        timely and the Class A Notes have not been previously disposed of by the

      (i) the
        provisions of this Section shall be in full force and effect;

       

      (ii) the

        hereunder) as the sole holder of the Class A Notes, and shall have no obligation
        to the Note Owners;

       

      (iii) to
        the
        extent that the provisions of this Section conflict with any other provisions

        shall be limited to those established by law and agreements between such
        Note
        Owners and the Clearing Agency and/or the Clearing Agency Participants pursuant
        to the Note Depository Agreement. Unless and until Definitive Notes are issued
        pursuant to Section 2.12 below, the initial Clearing Agency will make book

        or directions of Holders of Class A Notes evidencing a specified percentage
        of
        the Outstanding Amount of the Class A Notes, the Clearing Agency shall be
        deemed
        to represent such percentage only to the extent that it has received
        instructions to such effect from Note Owners and/or Clearing Agency Participants
        owning or representing, respectively, such required percentage of security
        entitlements with respect to the Class A Notes and has delivered such
        instructions to the Indenture Trustee.

       

      Section

        Note Owners pursuant to Section 2.12, the Indenture Trustee shall give all
        such
        notices and communications specified herein to be given to Holders of the

        Owners.

       

      Section
        2.12 Definitive
        Notes.
        If (i)

        that
        the Clearing Agency is no longer willing or able to properly discharge its
        responsibilities with respect to the Book Entry Notes and the Clearing Agency
        or
        the Issuer is unable to locate a qualified successor, (ii) the Issuer at
        its
        option advises the Indenture Trustee in writing that it elects to terminate
        the
        book entry system through the Clearing Agency or (iii) after the occurrence
        of
        an Event of Default, Note Owners of security entitlements representing
        beneficial interests aggregating at least a majority of the Outstanding Amount
        of such Class A Notes advise the Clearing Agency in writing that the
        continuation of a book entry system through the Clearing Agency is no longer
        in
        the best interests of such Note Owners, then the Clearing Agency shall notify
        all Note Owners and the Indenture Trustee of the occurrence of such event
        and of
        the availability of Definitive Notes to Note Owners requesting the same.
        Upon
        surrender to the Indenture Trustee of the typewritten Class A Notes representing
        the Book Entry Notes by the Clearing Agency, accompanied by registration
        instructions, the Issuer shall execute and the Indenture Trustee shall
        authenticate the Definitive Notes in accordance with theinstructions of the
        Clearing Agency. None of the Issuer, the Note Registrar or the Indenture
        Trustee
        shall be liable for any delay in delivery of such instructions and may
        conclusively rely on, and shall be protected in relying on, such instructions.
        Upon the issuance of Definitive Notes, the Indenture Trustee and the Note
        Registrar shall recognize the Holders of the Definitive Notes as
        Noteholders.

        Treatment.
        The
        Issuer has entered into this Indenture, and the Class A Notes will be issued,
        with the intention that, for all tax purposes, the Class A Notes will qualify
        as
        indebtedness secured by the Trust Estate. The Issuer, by entering into this
        Indenture, and each Noteholder, by its acceptance of a Class A Note (and
        each
        Note Owner by its acceptance of a security entitlement with respect to the
        applicable Book Entry Note), agree to treat the Class A Notes for all purposes
        as indebtedness of the Issuer.

        of Principal and Interest.
        The
        Issuer will duly and punctually pay (or will cause to be duly and punctually
        paid) the principal of and interest on the Class A Notes in accordance with
        the
        terms of the Class A Notes and this Indenture. Without limiting the foregoing,
        the Indenture Trustee shall, pursuant to Section 5.01 of the Sale and Servicing
        Agreement, distribute all amounts on deposit in the Distribution Account
        on each
        Payment Date deposited therein pursuant to the Sale and Servicing Agreement,
        and
        held therein for distribution to the Noteholders and the Insurer for the
        benefit
        of such Noteholders and the Insurer. Amounts properly withheld under the
        Code by
        any Person from a payment to any Noteholder of interest and/or principal
        shall
        be considered as having been paid by the Issuer to such Noteholder for all
        purposes of this Indenture.

       

      The
        Class
        A Notes shall be non-recourse obligations of the Issuer and shall be limited
        in
right
        of
        payment to amounts available from the Trust Estate, as provided in this
        Indenture.
        The
        Issuer
        shall not otherwise be liable for payments on the Class A Notes. If any other
        provision of this Indenture shall be deemed to conflict with the provisions
        of
        this Section 3.1, the provisions of this Section 3.1 shall control.

       

      Section
        3.2 Maintenance
        of Office or Agency.
        The
        Issuer will maintain an office or
        agency
        where
        Class A
        Notes
        may be surrendered
        for registration
        of transfer or exchange,
        and

        notices and demands to or upon the Issuer in respect of the Class A Notes
        and
        this Indenture
        may be served.
        The
        Issuer hereby initially appoints the Indenture Trustee to serve as
        its
        agent
        for the foregoing purposes and to serve as Paying Agent with respect to the
        Class A Notes. If at any time the Issuer shall fail to maintain any such
        office
        or agency or shall fail to furnish the Indenture Trustee with the address
        thereof, such surrenders, notices and demands may be made or served at the
        Corporate Trust Office, and the Issuer hereby appoints the Indenture Trustee
        as
        its agent to receive all such surrenders, notices and demands.

      Section
        3.3 Money

        As
        provided in Section 8.2(a) and (b), all payments of amounts due and payable
        with

        Section
        8.2(c) shall be made on behalf of the issuer by the Indenture Trustee or
        by the
        Paying Agent,
        and no amounts so withdrawn from the Distribution Account for payments on
        the

        3.3.

       

      Any
        Paying Agent shall be appointed by Issuer Order with written notice thereof
        to
        the Indenture Trustee and the Insurer. Any Paying Agent appointed by the
        Issuer
        shall be a Person who
        would
        be eligible to be Indenture Trustee hereunder as provided in Section 6.11
        hereof. The
        Issuer
        shall not appoint any Paying Agent (other than the Indenture Trustee) which
        is
        not, at the time of such appointment, a Depository Institution.

       

      The
        Issuer will cause each Paying Agent to execute and deliver to the Indenture
        Trustee
        an
        instrument in which such Paying Agent shall agree with the
        Indenture Trustee (and if the Indenture Trustee acts as Paying Agent, it
        hereby
        so agrees), subject to the provisions of this Section 3.3, that such Paying
        Agent will:

       

      (i) hold
        all
        sums held by it for the payment of amounts’ due with respect to the Class A
        Notes in trust for the benefit of the Persons entitled thereto until such
        sums
        shall be
        paid
        to such Persons or otherwise disposed of as herein provided and pay such
        sums
        to
        such
        Persons as herein provided;

       

      (ii) give
        the
        Indenture Trustee and the Insurer notice of any default by the issuer
        (or any other obligor upon the Class A Notes) (such notice to be given within
        three Business
        Days)
        of which
        it has actual knowledge in the making of any payment required
        to be
        made with respect to the Class A Notes;

       

      (iii) at
        any
time
        during
the
        continuance of any such default, upon the written request
        of the
        Indenture Trustee
        or the
        Insurer, forthwith pay to the Indenture Trustee all sums

        as those upon which the sums were held by such Paying Agent; and upon such
        payment by any Paying Agent to the Indenture Trustee, such Paying Agent shall
        be
        released from all further liability with respect to such money.

        this Indenture.

    

     

    Section
      3.7 Performance of Obligations: Servicing of Mortgage
      Loans.

     

    (a) The
      Issuer will not take any action and will use its best efforts not to permit
      any
      action to be taken by others that would release any Person from any of such
      Person’s covenants or obligations under any instrument or agreement included in
      the Trust Estate or that would result in the amendment, hypothecation,
      subordination, termination or discharge of, or impair the validity or
      effectiveness of, any such instrument or agreement, except as expressly provided
      in this Indenture, the Sale and Servicing Agreement or such other instrument
      or
      agreement.

     

    (b) The
      Issuer may contract with or otherwise obtain the assistance of other Persons
      to
      assist it in performing its duties under this Indenture, and any performance
      of
      such duties by a Person identified to the Indenture Trustee in an Officer’s
      Certificate of the Issuer shall be deemed to be action taken by the Issuer.
      Initially, the Issuer has contracted with the Administrator to assist the Issuer
      in performing its duties under this Indenture.

     

    (c) The
      Issuer will punctually perform and observe all of its obligations and agreements
      contained in this Indenture, the Transaction Documents and in the instruments
      and agreements included in the Trust Estate, including but not limited to (i)
      filing or causing to be filed all UCC financing statements and continuation
      statements required to be filed by the terms of this Indenture, the Mortgage
      Loan Purchase Agreement and the Sale and Servicing Agreement and (ii) recording
      or causing to be recorded all Mortgages, Assignments of Mortgage, all
      intervening Assignments of Mortgage and all assumption and modification
      agreements required to be recorded by the terms of the Sale and Servicing
      Agreement and the Mortgage Loan Purchase Agreement, in accordance with and
      within the time periods provided for in this Indenture and/or the Sale and
      Servicing Agreement, as applicable. Except as otherwise expressly provided
      therein, the Issuer shall not waive, amend, modify, supplement or terminate
      any
      Transaction Document or any provision thereof without the consent of the
      Indenture Trustee, the Insurer and the Holders of at least a majority of the
      Outstanding Amount of the Class A Notes.

     

    

    
      
        
          
          

        

        
          22

          
            

          

        

        
          
          

        

      

    

    

    
      (d) Subject
        to the terms of the Sale and Servicing Agreement, if the Issuer shall have
        knowledge of the occurrence of an Event of Servicing Termination under the
        Sale
        and Servicing Agreement, the Issuer shall promptly notify the Indenture Trustee,
        the Seller, the Depositor, the Insurer, the Master Servicer and the Rating
        Agencies thereof, and shall specify in such notice the action, if any, the
        Master Servicer is taking with respect of such default. If such an Event
        of
        Servicing Termination shall arise from the failure of the Master Servicer
        to
        perform any of its duties or obligations under the Sale and Servicing Agreement
        with respect to the Mortgage Loans, the Issuer shall take all reasonable
        steps
        available to it to remedy or cause to be remedied such failure.

       
(e)
      Subject to the terms of the Sale and Servicing Agreement, as promptly as
      possible after the giving of notice of termination to the Master Servicer of
      the
      Master Servicer’s rights and powers pursuant to Section 8.01 of the Sale and
      Servicing Agreement, a successor servicer (the “Successor Master Servicer”)
      shall be appointed pursuant to Section 7.02 of the Sale and Servicing Agreement.
      If the Indenture Trustee shall succeed to the Master Servicer’s duties as
      servicer of the Mortgage Loans as provided therein, it shall do so in its
      individual capacity and not in its capacity as Indenture Trustee and,
      accordingly, the provisions of Article VI hereof shall be inapplicable to the
      Indenture Trustee in its duties as successor Master Servicer and the servicing
      of the Mortgage Loans, but rather the provisions of the Sale and Servicing
      Agreement shall be applicable. In case the Indenture Trustee shall become
      successor Master Servicer under the Sale and Servicing Agreement, the Indenture
      Trustee shall be entitled to appoint as Successor Master Servicer any one of
      its
      Affiliates reasonably acceptable to the Insurer.

     

    (f) Without
      derogating from the absolute nature of the assignment granted to the Indenture
      Trustee under this Indenture or the rights of the Indenture Trustee hereunder,
      the Issuer agrees (i) that it will not, without the prior written consent of
      the
      Indenture Trustee (acting at the direction of the holders of at least 51% of
      the
      Outstanding Amount of the Class A Notes) and the Insurer (which consent shall
      not be unreasonably withheld), amend, modify, waive, supplement, terminate
      or
      surrender, or agree to any amendment, modification, supplement, termination,
      waiver or surrender of, the terms of the Trust Estate (except to the extent
      otherwise provided in the Sale and Servicing Agreement or the other Transaction
      Documents), or waive timely performance or observance by the Master Servicer
      or
      the Seller under the Sale and Servicing Agreement; and (ii) that any such
      amendment shall not (A) increase or reduce in any manner the amount of, or
      accelerate or delay the timing of, distributions that are required to be made
      for the benefit of the Noteholders or (B) reduce the percentage of the Class
      A
      Notes, set forth in Section 9.2, that is required to consent to any such
      amendment, without the consent of the Holders of all the outstanding Class
      A
      Notes. If any such amendment, modification, supplement or waiver shall be so
      consented to by the Indenture Trustee (acting at the direction of the holders
      of
      at least 51% of the Outstanding Amount of the Class A Notes) and the Insurer,
      the Issuer agrees, promptly following a request by the Indenture Trustee or
      the
      Insurer to do so, to execute and deliver, in its own name and at its own
      expense, such agreements, instruments, consents and other documents as the
      Indenture Trustee or the Insurer may deem necessary or appropriate in the
      circumstances.

      Section
        3.8 Negative
        Covenants.
        So long
        as any Class A Notes are Outstanding, the Issuer shall not, unless the Insurer
        otherwise consents in writing:

       

    

    (a) except
      as

      assets
      of the
      Issuer, including those included in the
      Trust
      Estate, unless directed
      to do so
      by the Indenture Trustee and consented to by the Insurer;

     

    (b) claim
      any
      credit on, or make any deduction from the principal or interest payable in
      respect of, the Class A Notes (other than amounts properly withheld from such
      payments under the Code) or assert any claim against any present or former
      Noteholder by reason of the payment of the taxes levied or assessed upon any
      part of the Trust Estate;

     

    (c) engage
      in
      any business or activity other than as permitted by the Trust Agreement or
      other
      than in connection with, or relating to, the issuance of Class A Notes pursuant
      to this Indenture and the Transferor Interest pursuant to the Trust Agreement,

    (d) issue
      debt obligations under any other indenture;

     

    (e) incur
      or
      assume any indebtedness or guaranty any indebtedness of any Person, except
      for
      such indebtedness as may be incurred by the Issuer in connection with the
      issuance of the Class A Notes pursuant to this Indenture;

     

    (f) dissolve
      or liquidate in whole or in part, or, subject to Section 3.16, merge or
      consolidate with any other Person;

     

    (g) (A)
      permit the validity or effectiveness of this Indenture to be impaired, or permit
      the lien of this Indenture to be amended, hypothecated, subordinated, terminated
      or discharged, or permit any Person to be released from any covenants or

      Indenture) to be created on or extend to or otherwise arise upon or burden

      Trust Estate or any part thereof or any interest therein or the proceeds thereof
      (other than tax liens, mechanics’ liens and other liens that arise by operation
      of law, in each case on any of the Mortgaged Properties and arising solely
      as a
      result of an action or omission of the related Mortgagor) or (C) permit the
      lien
      of this Indenture not to constitute a valid first priority (other than with

      to maintain and continue the first-priority perfected security interest of
      the
      Indenture Trustee in the Collateral; or

      company” under the 1940 Act.

      of Maturity; Rescission and Annulment.
      If an

      with the
      written consent of the Insurer, or shall at the direction of the Insurer or
      upon
      the prior written direction of the Holders of Class A Notes representing not
      less than a majority of the Outstanding Amount of the Class A Notes, declare
      all
      the Class A Notes to be immediately due and payable, by a notice in writing
      to
      the Issuer and the Insurer (and to the Indenture Trustee if given
      by
      Noteholders), and upon any such declaration the unpaid principal
      amount of such Class A
      Notes,
      together with accrued and unpaid interest thereon through the date of
      acceleration, shall become immediately due and payable.

     

    At
      any
      time after such declaration of acceleration of maturity has been made and before

      Indenture Trustee as hereinafter in this Article V provided, the Insurer or
      the
      Holders of Class A Notes representing a majority of the Outstanding Amount
      of
      the related Class A Notes, with the written consent of the Insurer, by written
      notice to the Issuer and the Indenture Trustee, may rescind and annul such
      declaration and its consequences if:

     

    (a) the
      Issuer has paid or deposited with the Indenture Trustee a sum sufficient to
      pay:

     

    (i) all
      payments of principal of and interest on all Class A Notes and all other amounts
      that would then be due hereunder or hpon such Class A Notes and to the Insurer
      if the Event of Default giving rise to such acceleration had not occurred;
      and

     

    (ii) all
      sums
      paid or advanced by the Indenture Trustee hereunder and the reasonable
      compensation, expenses, disbursements and advances of the Indenture Trustee

    No
      such rescission
      shall affect any subsequent default or impair any right
      consequent
      thereto.

      of the principal of or any installment of the principal of any Class A Note

      the same becomes due and payable, and such default continues for a period of
      five (5) days, the Issuer will, upon demand of the Indenture Trustee or the
      Insurer if the Insurer has made a payment under the Insurance Policy, pay to

      of the Class A Notes or the insurer, the whole amount then due and payable
      on
      such Class A Notes for principal and interest, with interest upon the overdue
      principal and, to the extent payment at such rate of interest shall be legally
      enforceable, upon overdue installments of interest at the rate borne by the
      Class A Notes and in addition thereto such further amount as shall be sufficient
      to cover the costs and expenses of collection, including the reasonable
      compensation, expenses, disbursements and advances of the Indenture Trustee,
      the
      Insurer and its agents and counsel.

      direction of the Insurer, institute a Proceeding for the collection of the
      sums
      so due and unpaid, and may prosecute such Proceeding to judgment or final
      decree, and may enforce the same against the Issuer or other obligor upon such
      Class A Notes and collect in the manner provided by law out of the property
      of
      the Issuer or other obligor upon such Class A Notes, wherever situated, the
      moneys adjudged or decreed to be payable.

     

    (c) If
      an
      Event of Default occurs and is continuing, the Indenture Trustee may, with
      the
      consent of the Insurer, and shall at the written direction of the Insurer or
      of
      the Holders of 51% or more of the Outstanding Amount of the Class A Notes,
      with
      the consent of the Insurer, as more particularly provided in Section 5.4 below,
      proceed to protect and enforce its rights and the rights of the Noteholders
      and
      the Insurer, by such appropriate Proceedings as the Insurer shall deem
      most
      effective to protect and enforce any such rights whether for the specific
      enforcement of any covenant or agreement in this Indenture or in aid of the
      exercise of any power granted herein, or to enforce any other proper remedy
      or
      legal or equitable right vested in the Indenture Trustee by this Indenture
      or by
      law.

      Trust Estate, Proceedings under Title 11 of the United States Code or any other
      applicable federal or state bankruptcy, insolvency or other similar law, or

    Section
      5.4 Remedies;
      Priorities.

     

    (a) If
      an
      Event of Default shall have occurred and be continuing of which a Responsible
      Officer of the Indenture has actual knowledge, the Indenture Trustee may with
      the consent of the Insurer, or, at the direction of the Insurer, shall or,
      if an
      Insurer Default shall be continuing, at the direction of a majority of the
      Holders of the Class A Notes shall, do one or more of the following (subject
      to
      Section 5.5 below):

     

    (i) institute
      Proceedings in its own name and as trustee of an express trust for the
      collection of all amounts then payable on the related Class A Notes or under
      this Indenture with respect thereto, whether by declaration or otherwise, and
      all amounts payable under the Insurance and Indemnity Agreement, enforce any
      judgment obtained, and collect from the Issuer and any other obligor upon such
      Class A Notes moneys adjudged due;

     

    (ii) institute
      Proceedings from time to time for the complete or partial foreclosure of this
      Indenture with respect to the Trust Estate;

     

    (iii) exercise
      any remedies of a secured party under the UCC and take any other appropriate
      action to protect and enforce the rights and remedies of the Indenture Trustee
      or the Noteholders or the Insurer; and

     

    (iv) sell
      the
      Trust Estate or any portion thereof or rights or interest therein in a
      commercially reasonable manner, at one or more public or private sales called
      and conducted in any manner permitted by law;

     

    provided,
      however, that the Indenture Trustee may not sell or otherwise liquidate the
      Trust Estate following an Event of Default, unless (A) the Indenture Trustee
      obtains the consent of the Insurer and the Holders of 100% of the Outstanding
      Amount of the Class A Notes, (B) the proceeds of such
      sale
      or liquidation distributable to the Noteholders are sufficient to discharge
      in
      full all amounts
      then due and unpaid upon such Class A Notes for principal and interest and
      to
      reimburse the Insurer for any unreimbursed Insured Payments and any other
      amounts due the Insurer under the Insurance and Indemnity Agreement or (C)
      the
      Indenture Trustee determines that the Trust Estate will not continue to provide
      sufficient funds for the payment of principal of and
      interest on the Class A Notes as they would have become due if the Class A
      Notes
      had not been declared due and payable, and the Indenture Trustee obtains the
      consent of the Insurer and the Holders of 66 213% of the Outstanding Amount
      of
      the Class A Notes. In determining such sufficiency or insufficiency with respect
      to clauses (B) and (C) above, the Indenture Trustee may, but need not, obtain
      and rely upon an opinion of an Independent investment banking or accounting
      firm
      of national reputation as to the feasibility of such proposed action and as
      to
      the sufficiency of the Trust Estate for such purpose.

     

    (b) If
      the
      Indenture Trustee collects any money or property pursuant to this Article V,
      the
      Indenture Trustee and the Paying Agent shall pay out the money or property
      in
      the following order:

    THIRD:
      to
      the Indenture Trustee for the Indenture Trustee Fee then due; 34

      zero;

     

    SIXTH:
      to
      the Insurer, any other amounts owed to the Insurer under the Insurance and
      Indemnity Agreement;

     

    SEVENTH:
      to the Indenture Trustee for any other amounts then due and outstanding;
      and

     

    EIGHTH:
      to the Paying Agent under the Trust Agreement, as applicable, for any amounts
      to
      be distributed to the holder of the Transferor Interest, in the manner set
      forth
      in Section 5.01 of the Sale and Servicing Agreement.

     

    The
      Indenture Trustee may fix a record date and payment date for any payment to
      be
      made to the Noteholders pursuant to this Section 5.4. At least 15 days before
      such record date, the
      Indenture Trustee shall mail to each Noteholder, the Insurer and the Issuer
      a
      notice
      that
      states
      the
      record date, the payment date and the amount to be paid.

     

    Section
      5.5 Optional
      Preservation of the Trust Estate.
      If the
      Class A Notes have been declared to be due and payable under Section 5.2 above
      following an Event of Default and such declaration and its consequences have
      not
      been rescinded and annulled, the Indenture Trustee may with the consent of
      the
      Insurer, but need not (but shall at the written
      direction of the Insurer), elect to maintain possession of the Trust Estate.
      It
      is the desire of the parties hereto and the Noteholders that there be at all
      times sufficient funds for the payment of principal of and interest on the
      Class
      A Notes (although the parties hereto understand that there exists the
      possibility of a shortfall in collections of the Mortgage Loans), and the
      Indenture Trustee shall take such desire into account when determining whether
      or not to maintain possession of the Trust Estate. In determining whether to
      maintain possession of the Trust Estate, the Indenture Trustee may, but need
      not, obtain and rely upon an opinion of an Independent investment banking or
      accounting firm of national reputation as to the feasibility of such proposed
      action and as to the sufficiency of the Trust Estate for such
      purpose.

    Section
      5.6 Limitation
      of Suits.
      No
      Holder of any Class A Note shall have any right to institute any Proceeding,
      judicial or otherwise, with respect to this Indenture or for the appointment
      of
      a receiver or trustee, or for any other remedy hereunder, unless the Insurer
      has
      otherwise consented in writing thereto and:

     

    (a) such
      Holder has previously given written notice to the Indenture Trustee of a
      continuing Event of Default;

     

    (b) the
      Holders of not less than 25% of the Outstanding Amount of the Class A Notes
      have
      made written request to the Indenture Trustee to institute such Proceeding
      in
      respect of such Event of Default in its own name as Indenture Trustee
      hereunder;

     

    (c) such
      Holder or Holders have offered to the Indenture Trustee reasonable indemnity
      against the costs, expenses and liabilities to be incurred in complying with
      such request;

     

    (d) the
      Indenture Trustee for 60 days after its receipt of such notice, request and
      offer of indemnity has failed to institute such Proceedings; and

     

    (e) no
      direction inconsistent with such written request has been given to the Indenture
      Trustee during such 60 day period by the Holders of a majority of the
      Outstanding Amount of the Class A Notes.

     

    It
      is
      understood and intended that no Noteholders shall have any right
      in
      any manner whatever
      by virtue
      of,
      or by availing of, any provision of this Indenture to affect, disturb
      or
      prejudice the rights of any other Noteholders or to obtain or to seek to obtain
      priority or preference
      over any other Holders or to enforce any right
      under
      this Indenture,
      except
      in the
      manner
      herein provided.

     

    Section
      5.7 Unconditional
      Rights of Noteholders To Receive Principal and Interest.
      Notwithstanding any other provisions in this Indenture, the Holder of any Class
      A Note shall have the right, which is absolute and unconditional, to receive
      payment of the principal of and interest, if any, on such Class A Note on or
      after the respective due date thereof expressed in such
      Class A Note or in this Indenture
      (or,
      in the case of redemption,
      on
      or after the Redemption Date)
      to
      the extent funds are
      available
      therefor out of the Trust
      Estate
      and to institute suit for the
      enforcement of any such payment, and such right shall not be impaired without
      the consent of such Holder.

     

    Section
      5.8 Restoration
      of Rights and Remedies.
      If the
      Indenture Trustee or any Noteholder has instituted any Proceeding to enforce
      any
      right or remedy under this Indenture and such Proceeding has been discontinued
      or abandoned for any reason or has been determined adversely to the Indenture
      Trustee or to such Noteholder, then and in every such case the Issuer, the
      Indenture Trustee and the Noteholders shall, subject to any determination in
      such Proceeding, be restored severally and respectively to their former
      positions hereunder, and thereafter all rights and remedies of the Indenture
      Trustee and the Noteholders shall continue as though no such Proceeding had
      been
      instituted.

     

    Section
      5.9 Rights
      and Remedies Cumulative.
      No
      right or remedy herein conferred upon or reserved to the Indenture Trustee,
      the
      Insurer or to the Noteholders is intended to be exclusive of any other right
      or
      remedy, and every right and remedy shall, to the extent permitted by law, be
      cumulative and in addition to every other right and remedy given hereunder
      or
      now or hereafter existing at law or in equity or otherwise. The assertion or
      employment of any right or remedy hereunder, or otherwise, shall not prevent
      the
      concurrent assertion or employment of any other appropriate right or
      remedy.

    Section
      5.10 Delay
      or Omission Not a Waiver.
      No
      delay or omission of the Indenture Trustee, the Insurer or any Noteholder to
      exercise any right or remedy accruing upon any Default or Event of Default
      shall
      impair any such right or remedy or constitute a waiver of any such Default
      or
      Event of Default or an acquiescence therein. Every right and remedy given
by
      this
      Article V or by law to the Indenture Trustee, the Insurer or to the Noteholders
      may be exercised from time to time, and as often as may be deemed expedient,
      by
      the Indenture Trustee, the Insurer or by the Noteholders, as the case may
      be.

     

    Section
      5.11 Control
      by Noteholders.
      The
      Insurer (so long as no Insurer Default exists) or if an Insurer Default exists
      the Holders of a majority of the Outstanding Amount of the Class A Notes, shall
      have the right to direct the time, method and place of conducting any Proceeding
      for any remedy available to the Indenture Trustee with respect to the Class
      A
      Notes or exercising any trust or power conferred on the Indenture Trustee;
      provided that:

     

    (a) such
      direction shall not be in conflict with any rule of law or with this
      Indenture;

     

    (b) [reserved];

     

    (c) if
      the
      conditions set forth in Section 5.5 above have been satisfied and the Indenture
      Trustee elects to retain the Trust Estate pursuant to such Section 5.5, then
      any
      direction to the Indenture Trustee by Holders of Class A Notes representing
      less
      than 100% of the Outstanding Amount of the Class A Notes to sell or liquidate
      the Trust Estate shall be of no force and effect; and

     

    (d) the
      Indenture Trustee may take any other action deemed proper by the Indenture
      Trustee that is not inconsistent with such direction.

     

    Notwithstanding
      the rights of the Noteholders set forth in this Section 5.11, subject to Section
      6.1 hereof, the Indenture Trustee need not take any action that it determines
      might involve it in liability or might materially adversely affect the rights
      of
      any Noteholders not consenting to such action.

     

    Section
      5.12 Waiver
      of Past Defaults.
      Prior
      to the declaration of the acceleration of the maturity of the Class A Notes
      as
      provided in Section 5.2 above, the Insurer (so long as no Insurer Default
      exists) or the Holders of Class A Notes representing not less than a majority
      of
      the Outstanding Amount of the Class A Notes, with the consent of the Insurer
      (so
      long as no Insurer
      Default
      exists), may waive any past
      Default or Event of Default and its consequences except
      a
      Default (a) in the payment of principal of or interest on any of the Class
      A
      Notes or(b) in respect of a covenant or provision hereof that cannot be modified
      or amended without the consent of the Holder of each Class A Note. In the case
      of any such waiver, the Issuer, the Insurer, the Indenture Trustee and the
      Holders of the Class A Notes shall be restored to their former positions and
      rights hereunder, respectively; but no such waiver shall extend to any
      subsequent or other Default or impair any right consequent thereto.

    Upon
      any
      such waiver, such Default shall cease to exist and be deemed to have been cured
      and not to have occurred, and any Event of Default arising therefrom shall
      be
      deemed to have been cured and not to have occurred, for every purpose of this
      Indenture; but no such waiver shall extend to any subsequent or other Default
      or
      Event of Default or impair any right consequent thereto.

     

    Section
      5.13 Undertaking
      for Costs.
      All
      parties to this Indenture agree, and each Holder of any Class A Note by such
      Holder’s acceptance thereof shall be deemed to have agreed, that any court may
      in its discretion require, in any suit for the enforcement of any right or
      remedy under this Indenture, or in any suit against the Indenture Trustee for
      any action taken, suffered or omitted by it as Indenture Trustee, the filing
      by
      any party litigant in such suit of an undertaking to pay the costs of such
      suit,
      and that such court may in its discretion assess reasonable costs, including
      reasonable attorneys’ fees, against any party litigant in such suit, having due
      regard to the merits and good faith of the claims or defenses made by such
      party
      litigant; but the provisions of this Section shall not apply to (a) any suit
      instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder,
      or group of Noteholders, in each case holding in the aggregate more than 10%
      of
      the Outstanding Amount of the Class A Notes or (c) any suit instituted by any
      Noteholder for the enforcement of the payment of principal of or interest on
      any
      Class A Note on or after the respective due dates expressed in such Class A
      Note
      and in this Indenture (or, in the case of redemption, on or after the Redemption
      Date).

     

    Section
      5.14 Waiver
      of Stay or Extension Laws.
      The
      Issuer covenants (to the extent that it may lawfully do so) that it will not
      at
      any time insist upon, or plead or in any manner whatsoever, claim or take the
      benefit or advantage of, any stay or extension law wherever enacted, now or
      at
      any time hereafter in force, that may affect the covenants or the performance
      of
      this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby
      expressly waives all benefit or advantage of any such law, and covenants that
      it
      will not hinder, delay or impede the execution of any power herein granted
      to
      the Indenture Trustee, but will suffer and permit the execution of every such
      power as though no such law had been enacted.

     

    Section
      5.15 Action
      on Notes.
      The
      Indenture Trustee’s right to seek and recover judgment on the Class A Notes or
      under this Indenture shall not be affected by the seeking, obtaining or
      application of any other relief under or with respect to this Indenture. Neither
      the lien of this Indenture nor any rights or remedies of the Indenture Trustee
      or the Noteholders shall be impaired by the recovery of any judgment by the
      Indenture Trustee against the Issuer or by the levy of any execution under
      such
      judgment upon any portion of the Trust Estate or upon any of the assets of
      the
      Issuer. Any money or property collected by the Indenture Trustee shall be
      applied in accordance with Section 5.4(b) above.

     

    Section
      5.16 Performance
      and Enforcement of Certain Obligations.

     

    (a) Promptly
      following a request from the Insurer or the Indenture Trustee, with the consent
      of the Insurer to do so, the Issuer shall take all such lawful action as the
      Indenture Trustee or the Insurer, as applicable, may request to compel or secure
      the performance and observance by the Seller, the Depositor and the Master
      Servicer, as applicable, of each of their obligations to the Issuer under or
      in
      connection with the Sale and Servicing Agreement and other Transaction
      Documents, and to exercise any and all rights, remedies, powers and privileges
      lawfully available to the Issuer under or in connection with the Sale and
      Servicing Agreement and the other Transaction Documents to the extent and in
      the
      manner directed by the Indenture Trustee or the Insurer, as applicable,
      including the transmission of notices of default on the part of the Seller,
      the
      Depositor or the Master Servicer thereunder and the institution of legal or
      administrative actions or proceedings to compel or secure performance by the
      Seller, the Depositor or the Master Servicer of each of their obligations under
      the Sale and Servicing Agreement and the other Transaction
      Documents.

     

    

    
      
        
          
          

        

        
          41

          
            

          

        

        
          
          

        

      

    

    

    (b) If
      an
      Event of Default has occurred and is continuing, the Indenture Trustee, subject
      to the rights of the Insurer hereunder and under the Sale and Servicing
      Agreement, may, and at the direction (which direction shall be in writing or
      by
      telephone, confirmed in writing promptly thereafter) of the Insurer or the
      Holders of a majority of the Outstanding Amount if there is an Insurer Default
      shall, exercise all rights, remedies, powers, privileges and claims of the
      Issuer against the Seller, the Depositor or the Master Servicer under or in
      connection with the Sale and Servicing Agreement and the other Transaction
      Documents, including the right or power to take any action to compel or secure
      performance or observance by the Seller, the Depositor or the Master Servicer,
      as the case may be, of each of their obligations to the Issuer thereunder and
      to
      give any consent, request, notice, direction, approval, extension, or waiver
      under the Sale and Servicing Agreement and the other Transaction Documents,
      and
      any right of the Issuer to take such action shall be suspended.

      of Indenture Trustee.

     

    (a) If
      an
      Event of Default has occurred and is continuing, the Indenture Trustee shall
      exercise the rights and powers vested in it by this Indenture and use the same
      degree of care and skill in their exercise as a prudent person would exercise
      or
      use under the circumstanced in the conduct of such person’s own
      affairs.

     

    (b) Except
      during the continuance of an Event of Default.

     

    (i) the
      Indenture Trustee undertakes to perform such duties and only such duties as

      specifically set forth in this Indenture and no implied covenants or obligations
      shall be read into this Indenture against the Indenture Trustee;
      and

     

    (ii) in
      the
      absence of bad faith on its part, the Indenture Trustee may conclusively rely,
      as to the truth of the statements and the correctness of the opinions expressed
      therein, upon certificates or opinions furnished to the Indenture Trustee and
      conforming to the requirements of this Indenture; however, the Indenture Trustee
      shall examine the certificates and opinions to determine whether or not they
      conform to the requirements of this Indenture.

     

    

    
      
        
          
          

        

        
          42

          
            

          

        

        
          
          

        

      

    

    
       

      (c) The
        Indenture Trustee may not be relieved from liability for its own negligent
        action, its own negligent failure to act or its own willful misconduct, except
        that:

    (i) this
      paragraph does not limit the effect of paragraph (b) of this Section
      6.1;

     

    (ii) the
      Indenture Trustee shall not be liable for any error of judgment made in good
      faith by a Responsible Officer unless it is proved that the Indenture Trustee
      was negligent in ascertaining the pertinent facts; and

     

    (iii) the
      Indenture Trustee shall not be liable with respect to any action it takes or
      omits to take in good faith in accordance with a direction received by it
      pursuant to Section
      5.11 above or any direction from the Insurer that the Insurer is entitled to
      give under the terms of the Transaction Documents.

     

    (d) Every
      provision of this Indenture that in any way relates to the Indenture Trustee
      is
      subject to paragraphs (a), (b), (c) and (g) of this Section 6.1.

     

    (e) The
      Indenture Trustee shall not be liable for interest on any money received by

    (f) Money
      held in trust by the Indenture Trustee shall be segregated from other funds

      Sale
      and Servicing Agreement.

     

    (g) No
      provision of this Indenture shall require the Indenture Trustee to expend or
      risk its own funds or otherwise incur financial liability in the performance
      of
      any of its duties hereunder or in the exercise of any of its rights or powers,
      if it shall have reasonable grounds to believe that repayment of such funds
      or
      adequate indemnity against such risk or liability is not reasonably assured
      to
      it; and none of the provisions contained in this Indenture shall in any event
      require the Indenture Trustee to perform, or be responsible for the manner
      of
      performance of, any of the obligations of the Master Servicer, the Issuer or
      Transferor under this Indenture except during such time, if any, as the
      Indenture Trustee shall be the successor to, and be vested with the rights,
      duties, powers and privileges of, the Master Servicer in accordance with the
      terms of this Indenture.

     

    (h) The
      Indenture Trustee shall challenge or cause to be challenged any attempt at
      substantive consolidation of the assets and liabilities of the Issuer with
      those
      of any Transferor (as defined in the Trust Agreement) in connection with any
      insolvency proceeding of the Issuer.

     

    (i) Every
      provision of this Indenture relating to the conduct or affecting the liability
      of or affording protection to the Indenture Trustee shall be subject to the
      provisions of this Section 6.1 and to the provisions of the TIA.

     

    (j) Subject
      to the other provisions of this Indenture and without limiting the generality
      of
      this Section 6. 1, the Indenture Trustee shall have no duty (A) to see to any
      recording, filing, or depositing of this Indenture or any agreement referred
      to
      herein or any financing statement or continuation statement evidencing a
      security interest, or to see to the maintenance of any such recording or filing
      or depositing or to any rerecording, refiling or redepositing of any thereof,
      (B) to see to any insurance, (C) to see to the payment or discharge of any
      tax,
      assessment, or other governmental charge or any lien or encumbrance of any
      kind
      owing with respect to, assessed or levied against, any part of the Trust Estate
      other than from funds available in the Distribution Account, (D) to confirm
      or
      verify the contents of any reports or certificates of the Issuer, Insurer or

    Section
      6.2 Rights
      of Indenture Trustee.

     

    (a) The
      Indenture Trustee may conclusively rely and shall be fully protected in acting
      or refraining from acting on any resolution, certificate of auditors or any
      other certificate, statement, instrument, opinion, report, notice, request,
      consent, order, appraisal, bond or other paper or document believed by it to
      be
      genuine and to have been signed or presented by the proper person. The Indenture
      Trustee need not investigate any fact or matter stated in the
      document.

     

    (b) Before
      the Indenture Trustee acts or refrains from acting, it may require and shall
      be
      entitled to receive an Officer’s Certificate or an Opinion of Counsel. The
      Indenture Trustee shall not be liable for any action it takes or omits to take
      in good faith in reliance on an Officer’s Certificate or opinion of
      Counsel.

     

    (c) The
      Indenture trustee may execute any of the trusts or powers hereunder or perform
      any duties hereunder either directly or by or through agents or attorneys or
      a
      custodian or nominee and the Indenture Trustee shall not be responsible for
      any
      misconduct or negligence on the part of such agent, attorney, nominee or
      custodian appointed by the Indenture Trustee with due care.

     

    (d) The
      Indenture Trustee shall not be liable for any action it takes or omits to take
      in goal faith which it believes to be authorized or within its rights or powers;
      provided, however, that such action or omission by the Indenture Trustee does
      not constitute willful misconduct, negligence or bad faith.

     

    (e) The
      Indenture Trustee may consult with counsel, and the advice or opinion of counsel
      selected by it with due care with respect to legal matters relating to this
      Indenture, the Class A Notes and the Transaction Documents to which it is a
      party, shall be full and complete authorization and protection from liability
      in
      respect to any action taken, omitted or suffered by it hereunder in good faith
      and in accordance with the advice or opinion of such counsel.

     

    (f) The
      Indenture Trustee shall be under no obligation to exercise any of the trusts
      or
      powers vested in it by this Indenture or to institute, conduct or defend any
      litigation hereunder or in relation hereto at the request, order or direction
      of
      the Insurer or any of the Noteholders, pursuant to the provisions of this
      Indenture, unless the Insurer or such Noteholders shall have offered to the
      Indenture Trustee reasonable security or indemnity against the costs, expenses
      and liabilities which may be incurred therein or thereby; nothing contained
      herein shall, however, relieve the Indenture Trustee of the obligation, upon
      the
      occurrence of an Event of Default of which a Responsible Officer of the
      Indenture Trustee shall have actual knowledge (which has not been cured), to
      exercise such of the rights and powers vested in it by this Indenture, and
      to
      use the same degree of care and skill in their exercise, as a prudent person
      would exercise or use under the circumstances in the conduct of such person’s
      own affairs.

     

    

    
      
        
          
          

        

        
          44

          
            

          

        

        
          
          

        

      

    

    

    (g) The
      Indenture Trustee shall not be bound to make any investigation into the facts
      or
      matters stated in any resolution, certificate, statement, instrument, opinion,
      report, notice, request, consent, order, approval, bond or other paper or
      document, unless requested in writing to do so by the Insurer or the Majority
      Class A Noteholders; provided, however, that if the payment within a reasonable
      time to the Indenture Trustee of the costs, expenses or liabilities likely
      to be
      incurred by it in the making of such investigation is, in the opinion of the
      Indenture Trustee, not reasonably assured to the Indenture Trustee by the
      security afforded to it by the terms of this Indenture, the Indenture Trustee
      may require reasonable indemnity against such cost, expense or liability as
      a
      condition to taking any such action. The reasonable expense of every such
      examination shall be paid by the Issuer or, if paid by the Indenture Trustee,
      shall be repaid by the Issuer upon demand.

     

    (h) The
      right
      of the Indenture Trustee to perform any discretionary act enumerated in this
      Indenture shall not be construed as a duty, and the Indenture Trustee shall
      not
      be answerable for other than its negligence or willful misconduct in the
      performance of such act.

     

    (i) The
      Indenture Trustee shall not be required to give any bond or surety in respect
      of
      the execution of the Trust created hereby or the powers granted
      hereunder.

     

    (j) The
      Indenture Trustee shall have no liability in connection with the malfeasance
      or
      nonfeasance by the Issuer, the Master Servicer or the Administrator. The
      Indenture Trustee shall have no liability in connection with compliance by
      the
      Issuer or the Master Servicer with statutory or regulatory requirements related
      to the Collateral or the Trust Estate. The Indenture Trustee shall not make
      or
      be deemed to have made any representations or warranties with respect to the
      Collateral or the Trust Estate or the validity or sufficiency of any assignment
      of the Collateral or the Trust Estate to the Indenture Trustee.

     

    (k) In
      the
      event that the Indenture Trustee is also acting as Paying Agent or Registrar
      hereunder, the rights, protection, immunities and indemnities afforded to the
      Indenture Trustee pursuant to this Article VI shall also be afforded to such
      Paying Agent or Registrar.

     

    Section
      6.3 Individual
      Rights of Indenture Trustee.
      The
      Indenture Trustee in its individual or any other capacity may become the owner
      or pledgee of Class A Notes and may otherwise deal with the Issuer or its
      Affiliates with the same rights it would have if it were not Indenture Trustee.
      Any Paying Agent, Note Registrar, co registrar or co paying agent may do the
      same with like rights. However, the Indenture Trustee must comply with Sections
      6.11 and 6.12 below.

     

    

    
      
        
          
          

        

        
          45

          
            

          

        

        
          
          

        

      

    

    
       

      Section
        6.4 Indenture
        Trustee’s Disclaimer.
        The
        Indenture Trustee shall not be (i) responsible for and makes no representation
        as to the validity or adequacy of this Indenture or the Class A Notes, (ii)
        accountable for the Issuer’s use of the proceeds from the Class A Notes or (iii)
        responsible for any statement of the Issuer in this Indenture or in any document
        issued in connection with the sale of the Class A Notes or in the Class A
        Notes
        other than the Indenture Trustee’s certificate of
        authentication.

    Section
      6.5 Notice
      of Defaults.
      If a
      Default occurs and is continuing and if it is actually known to a Responsible
      Officer of the Indenture Trustee, the Indenture Trustee shall give prompt notice
      thereof to the Insurer. The Indenture Trustee shall not be charged with the
      knowledge of an Event of Default unless a Responsible Officer has received
      written notice or has actual knowledge thereof. The Indenture Trustee shall
      mail
      to each Noteholder, the Master Servicer and the Seller notice of the Default
      within 30 days after it occurs at the expense of the Issuer. Except in the
      case
      of a Default in payment of principal of or interest on any Class A Note, the
      Indenture Trustee may withhold the notice to the Noteholders if and so long
      as a
      committee of its Responsible Officers in good faith determines that withholding
      the notice is in the interests of Noteholders.

     

    Section
      6.6 Reports
      by Indenture Trustee to Holders.
      The
      Indenture Trustee shall deliver to each Noteholder such information as may
      be
      required to enable such holder to prepare its federal and state income tax
      returns. In addition, upon Issuer Request, the Indenture Trustee shall promptly
      furnish such information reasonably requested by the Issuer that is reasonably
      available to the Indenture Trustee to enable the Issuer to perform its federal
      and state income tax reporting obligations.

     

    Section
      6.7 Compensation
      and Indemnity.
      As
      compensation for its services hereunder, the Indenture Trustee shall be entitled
      to receive, on each Payment Date, the Indenture Trustee’s Fee pursuant to
      Section 5.01 of the Sale and Servicing Agreement (which compensation shall
      not
      be limited by any law on compensation of a trustee of an express trust) and
      shall be entitled to reimbursement for all reasonable out of pocket expenses
      incurred or made by it, including costs of collection, in addition to the
      compensation for its services. Such expenses shall include the reasonable
      compensation and expenses, disbursements and advances of the Indenture Trustee’s
      agents, counsel, accountants and experts. The Indenture Trustee shall be
      indemnified by the Master Servicer, and if not by the Master Servicer, then
      by
      the Trust Estate pursuant to the seventh clause of Section 5.4 herein against
      any and all loss, liability or expense (including attorneys’ fees) incurred by
      it in connection with the administration of this trust and the performance
      of
      its duties hereunder. The Indenture Trustee shall notify the Issuer promptly
      of
      any claim for which it may seek indemnity. Failure by the Indenture Trustee
      to
      so notify the Issuer shall not relieve the Issuer of its obligations hereunder.
      The Issuer shall defend any such claim, and the Indenture Trustee may have
      separate counsel and the Issuer shall pay the fees and expenses of such counsel.
      The Indenture Trustee shall not be entitled to any such reimbursement of any
      expense or to indemnification against any loss, liability or expense incurred
      by
      the Indenture Trustee through the Indenture Trustee’s own willful misconduct,
      negligence or bad faith. Anything in this Indenture to the contrary
      notwithstanding, in no event shall the Indenture Trustee be liable for special,
      indirect or consequential loss or damage of any kind whatsoever (including
      but
      not limited to lost profits), even if the Indenture Trustee has been advised
      of
      the likelihood of such loss or damage and regardless of the form of action.
      This
      indemnity shall survive the termination of this Indenture.

     

    

    
      
        
          
          

        

        
          46

          
            

          

        

        
          
          

        

      

    

    

    The
      Issuer’s payment obligations to the Indenture Trustee pursuant to this Section
      6.7 shall survive the discharge of this Indenture. When the Indenture Trustee
      incurs expenses or provides services after the occurrence of a Default specified
      in Section 5.1(e) or (f) hereof with respect to the Issuer, the expenses and
      fees for such services are intended to constitute expenses of administration
      under Title 11 of the United States Code or any other applicable federal or
      state bankruptcy, insolvency or similar law.

     

    Section
      6.8 Replacement
      of Indenture Trustee.
      No
      resignation or removal of the Indenture Trustee and no appointment of a
      successor Indenture Trustee shall become effective until the acceptance of
      appointment by the successor Indenture Trustee acceptable to the Insurer
      pursuant to this Section. The Indenture Trustee may resign at any time by so
      notifying the Issuer and the Insurer. As a condition to the effectiveness of
      any
      such resignation, at least 15 calendar days prior to the effective date of
      such
      resignation, the Indenture Trustee shall provide (x) written notice to the
      Depositor of any successor pursuant to this Section and (y) in writing and
      in
      form and substance reasonably satisfactory to the Depositor, all information
      reasonably requested by the Depositor in order to comply with its reporting
      obligation under Item 6.02 of Form 8-K with respect to the resignation of the
      Indenture Trustee. The Insurer or the Holders of a majority in Outstanding
      Amount of the Class A Notes (with the prior written consent of the Insurer)
      may
      remove the Indenture Trustee by so notifying the Indenture Trustee and the
      Insurer (if given by such Noteholders) and may appoint a successor Indenture
      Trustee acceptable to the Insurer. The Issuer shall (with the prior written
      consent of the Insurer) remove the Indenture Trustee if:

     

    (a) the
      Indenture Trustee fails to comply with Section 6.11 below;

     

    (b) the
      Indenture Trustee is adjudged a bankrupt or insolvent;

     

    (c) a
      receiver or other public officer takes charge of the Indenture Trustee or its
      property; or

     

    (d) the
      Indenture Trustee otherwise becomes incapable of acting.

     

    If
      the
      Indenture Trustee resigns or is removed or if a vacancy exists in the office
      of
Indenture
      Trustee
      for any reason
      (the Indenture Trustee in such event being referred to herein as
      the
      retiring Indenture Trustee), the Issuer shall promptly appoint a successor
      Indenture Trustee with the consent of the Insurer, which consent shall not
      be
      unreasonably withheld.

     

    A
      successor Indenture Trustee shall deliver a written acceptance of its
      appointment to the retiring Indenture Trustee and to the Issuer and shall
      provide to the Depositor, in writing and in form and substance reasonably
      satisfactory to the Depositor, all information reasonably requested by the
      Depositor in order to comply with its reporting obligation under Item 6.02
      of
      Form 8-K with respect to the resignation of the Indenture Trustee. Thereupon
      the
      resignation or removal of the retiring Indenture Trustee shall become effective,
      and the successor Indenture Trustee shall have all the rights, powers and duties
      of the Indenture Trustee under this Indenture. The successor Indenture Trustee
      shall mail a notice of its succession to Noteholders. The retiring Indenture
      Trustee shall promptly transfer all property held by it as Indenture Trustee
      to
      the successor Indenture Trustee.

     

    

    
      
        
          
          

        

        
          47

          
            

          

        

        
          
          

        

      

    

    
       

      If
        a
        successor Indenture Trustee does not take office within 60 days after the
        retiring Indenture Trustee resigns or is removed, the retiring Indenture
        Trustee, the Issuer or the Holders of a majority in Outstanding Amount of
        the
        Class A Notes may petition any court of competent jurisdiction for the
        appointment of a successor Indenture Trustee.

    If
      the
      Indenture Trustee fails to comply with Section 6.11 below, any Noteholder may
      (with the consent of the Insurer) petition any court of competent jurisdiction
      for the removal of the Indenture Trustee and the appointment of a successor
      Indenture Trustee.

     

    Notwithstanding
      the replacement of the Indenture Trustee pursuant to this Section 6.8, the
      Issuer’s obligations under Section 6.7 above shall continue for the benefit of
      the retiring Indenture Trustee.

     

    Section
      6.9 Successor
      Indenture Trustee by Merger.
      If the
      Indenture Trustee consolidates with, merges or converts into, or transfers
      all
      or substantially all its corporate trust business or assets to, another
      corporation or banking association, the resulting, surviving or transferee
      corporation without any further act shall be the successor Indenture Trustee;
      provided, that such corporation or banking association shall be otherwise
      qualified and eligible under Section 6.11 below. The
      Indenture Trustee shall provide (x) written notice to the Depositor of any
      successor due to merger or consolidation of the Indenture Trustee pursuant
      to
      this Section within five (5) days of the effectiveness of such merger or
      consolidation and (y) in writing and in form and substance reasonably
      satisfactory to the Depositor, all information reasonably requested by the
      Depositor in order to comply with its reporting obligation under Item 6.02
      of
      Form 8-K with respect to a replacement Indenture Trustee.

     

    In
      case
      at the time such successor or successors by merger, conversion or consolidation
      to the Indenture Trustee shall succeed to the trusts created by this Indenture
      any of the Class A Notes shall have been authenticated but not delivered, any
      such successor to the Indenture Trustee may adopt the certificate of
      authentication of any predecessor trustee, and deliver such Class A Notes so
      authenticated; and in case at that time any of the Class A Notes shall not
      have
      been authenticated, any successor to the Indenture Trustee may authenticate
      such
      Class A Notes either in the name of any predecessor hereunder or in the name
      of
      the successor to the Indenture Trustee; and in all such cases such certificates
      shall have the full force which it is anywhere in the Class A Notes or in this
      Indenture provided that the certificate of the Indenture Trustee shall
      have.

     

    Section
      6.10 Appointment
      of Co-Indenture Trustee or Separate Indenture Trustee.

     

    (a) Notwithstanding
      any other provisions of this Indenture, at any time, for the purpose of meeting
      any legal requirement of any jurisdiction in which any part of the Trust Estate
      may at the time be located, the Indenture Trustee shall have the power and
      may
      execute and deliver all instruments to appoint one or more Persons to act as
      a
      co trustee or co trustees, or separate trustee or separate trustees, of all
      or
      any part of the Trust Estate, and to vest in such Person or Persons, in such
      capacity and for the benefit of the Noteholders and the Insurer, such title
      to
      the Trust Estate, or any part hereof, and, subject to the other provisions
      of
      this Section 6.10, such powers, duties, obligations, rights and trusts as the
      Indenture Trustee may consider necessary or desirable. No co trustee or separate
      trustee hereunder shall be required to meet the terms of eligibility as a
      successor trustee under Section 6.11 below and no notice to Noteholders of
      the
      appointment of any co trustee or separate trustee shall be required under
      Section 6.8 above.

     

    

    
      
        
          
          

        

        
          48

          
            

          

        

        
          
          

        

      

    

    

    (b) Every
      separate trustee and co trustee shall, to the extent permitted by law, be
      appointed and act subject to the following provisions and
      conditions:

     

    (i) all
      rights, powers, duties and obligations conferred or imposed upon the Indenture
      Trustee shall be conferred or imposed upon and exercised or performed by the
      Indenture Trustee and such separate trustee or co trustee jointly (it being
      understood that such separate trustee or cc trustee is not authorized to act
      separately without the Indenture Trustee joining in such act), except to the
      extent that under any law of any jurisdiction in which any particular act or
      acts are to be performed the Indenture Trustee shall be incompetent or
      unqualified to perform such act or acts, in which event such rights, powers,
      duties and obligations (including the holding of title to the Trust Estate
      or
      any portion thereof in any such jurisdiction) shall be exercised and performed
      singly by such separate trustee or co trustee, but solely at the direction
      of
      the Indenture Trustee;

     

    (ii) no
      trustee hereunder shall be personally liable by reason of any act or omission
      of
      any other trustee hereunder; and

     

    (iii) the
      Indenture Trustee may at any time accept the resignation of or remove any
      separate trustee or co trustee.

     

    (c) Any
      notice, request or other writing given to the Indenture Trustee shall be deemed
      to have been given to each of the then separate trustees and co trustees, as
      effectively as if given to each of them. Every instrument appointing any
      separate trustee or co trustee shall refer to this Agreement and the conditions
      of this Article VI. Each separate trustee and co trustee, upon its acceptance
      of
      the trusts conferred, shall be vested with the estates or property specified
      in
      its instrument of appointment, jointly with the Indenture Trustee, subject
      to
      all the provisions of this Indenture, specifically including every provision
      of
      this Indenture relating to the
      conduct of, affecting the liability of, or affording protection to, the
      Indenture Trustee. Every such instrument shall be filed with the Indenture
      Trustee.

     

    (d) Any
      separate trustee or co trustee may at any time constitute the Indenture Trustee,
      its agent or attorney in fact with full power and authority, to the extent
      not
      prohibited by law, to do any lawful act under or in respect of this Agreement
      on
      its behalf and in its name. If any separate trustee or co trustee shall die,
      become incapable of acting, resign or be removed, all of its estates,
      properties, rights, remedies and trusts shall vest in and be exercised by the

      authenticated and delivered by the Indenture Trustee in exchange for Outstanding
      Class A Notes.

    Section

      of Documents Delivered to Indenture Trustee.
      In any
      case where several matters are required to be certified by, or covered by an
      opinion of, any specified Person, it is not necessary that all such matters
      be
      certified by, or covered by the opinion of, only one such Person, or that they
      be so certified or covered by only one document, but one such Person may certify
      or give an opinion with respect to some matters and one or more other such
      Persons as to other matters, and any such Person may certify or give an opinion
      as to such matters in one or several documents.

    Any
      certificate or opinion of an Authorized Officer of the Issuer may be based,
      insofar as
      it
      relates to legal matters, upon a certificate or opinion of, or representations
      by, counsel, unless such
      officer knows, or in the exercise of reasonable care should know, that the
      certificate or opinion or representations with respect to the matters upon
      which
      such officer’s certificate or opinion is based are erroneous. Any such
      certificate of an Authorized Officer or Opinion of Counsel may be based, insofar
      as it relates to factual matters, upon a certificate or opinion of, or
representations
      by, an officer or officers of the Master Servicer, the Transferor or the Issuer,
      stating that
      the
      information with respect to such factual matters is in the possession of the
      Master Servicer, the Transferor or the Issuer, unless such counsel knows, or
      in
      the exercise of reasonable care should know, that the certificate or opinion
      or
      representations with respect to such matters are erroneous.

    

    Where
      any
      Person is required to make, give or execute two or more applications, requests,
      consents, certificates, statements, opinions or other instruments under this
      Indenture, they may, but need not, be consolidated and form one
      instrument.

     

    Whenever
      in this Indenture, in connection with any application or certificate or report
      to the Indenture Trustee, it is provided that the Issuer shall deliver any
      document as a condition of the granting of such application, or as evidence
      of
      the Issuer’s compliance with any term hereof, it is intended that the truth and
      accuracy, at the time of the granting of such application or at the effective
      date of such certificate or report (as the case may be), of the facts and
      opinions stated in such document shall in such case be conditions precedent
      to
      the right of the Issuer to have such application granted or to the sufficiency
      of such certificate or report. The foregoing shall not, however, be construed
      to
      affect the Indenture Trustee’s right to rely upon the truth and accuracy of any
      statement or opinion contained in any such document as provided in Article
      VI
      hereof.

     

    Section

      expressly provided such action shall become effective when such instrument
      or
      instruments are delivered to the Indenture Trustee, and, where it is hereby
      expressly required, to the Issuer. Such instrument or instruments (and the
      action embodied therein and evidenced thereby) are herein sometimes referred
      to
      as the “Act” of the Noteholders signing such instrument or
      instruments.

     

    Proof
      of
      execution of any such instrument or of a writing appointing any such agent
      shall
      be sufficient for any purpose of this Indenture and (subject to Section 6.1
      hereof) conclusive in favor
      of

      and the Issuer, if made in the manner provided in this Section

      Note issued upon the registration thereof or in exchange therefor or in lieu
      thereof, in respect of anything .done, omitted or suffered to be done by the
      Indenture Trustee or the Issuer in reliance thereon, whether or not notation

    Section
      11.5 Notices
      to Noteholders, Waiver.
      Where
      this Indenture provides for notice to Noteholders of any event, such notice
      shall be sufficiently given (unless otherwise herein expressly provided) if
      in
      writing and mailed, first class, postage prepaid to each Noteholder affected
      by
      such event, at his address as it appears on the Note Register, not later
than
      the
      latest date, and not earlier than the earliest date, prescribed for the giving
      of such notice.
      In any
      case where notice to Noteholders is given by mail, neither the failure to mail
      such notice nor
      any
      defect in any notice so mailed to any particular Noteholder shall affect the
      sufficiency of such
      notice with respect to other Noteholders, and any notice that is mailed in
      the
      manner herein
      provided
      shall conclusively be presumed to have been duly given.

     

    Where
      this Indenture provides for notice in any manner, such notice may be waived
      in
      writing by any Person entitled to receive such notice, either before or after
      the event, and such waiver shall be the equivalent of such notice. Waivers
      of
      notice by Noteholders shall be filed with the Indenture Trustee but such filing
      shall not be a condition precedent to the validity of any action taken in
      reliance upon such a waiver.

     

    In
      case,
      by reason of the suspension of regular mail service as a result of a strike,
      work stoppage or similar activity, it shall be impractical to mail notice of
      any
      event to Noteholders when such notice is required to be given pursuant to any
      provision of this Indenture, then any manner of giving such notice as shall
      be
      satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving
      of such notice.

     

    Where
      this Indenture provides for notice to the Rating Agencies, failure to give
      such
      notice shall not affect any other rights or obligations created
      hereunder.

     

    Section
      11.6 Rights
      of the Insurer to Exercise Rights of Noteholders.
      By
      accepting its Class A Note, each Noteholder agrees that unless an Insurer
      Default exists,
      the Insurer shall have the right to exercise all rights of the Noteholders
      as
      specified under
      this
      Agreement without any further consent of the Noteholders. Any right conferred
      to
      the Insurer hereunder shall be suspended and shall run to the benefit of the
      Noteholders during any period in which there exists an Insurer Default,
      provided, however, that during an Insurer Default, the consent of the Insurer
      must be obtained with respect to any amendments that may materially adversely
      affect the Insurer. Upon the payment of any Insurance Policy Payment Amount
      in
      accordance with the terms of the Insurance Policy, the Insurer shall be fully
      subrogated to the rights of the Noteholders to receive the amount so paid and
      shall be deemed to be a Noteholder with respect thereto.

     

    Section
      11.7 Conflict
      with Trust Indenture Act.
      If any
      provision hereof limits, qualifies or conflicts with another provision hereof
      that is required to be included in this Indenture by any of the provisions
      of
      the Trust Indenture Act, such required provision shall control.

     

    The
      provisions of TIA Sections 310 through 317 that impose duties on any person
      (including the provisions automatically deemed included herein unless expressly
      excluded by this Indenture) are a part of and govern this Indenture, whether
      or
      not physically contained herein.

      agreements of the Indenture Trustee in this Indenture shall bind its successors,
      co trustees and agents.

    

    Section
      11.10 Separability.
      In
      case
      any provision in this Indenture or in the Class A
      Notes
      shall be invalid, illegal or unenforceable, the validity, legality, and
      enforceability of the remaining provisions shall not in any way be affected
      or
      impaired thereby.

     

    Section

      any
      Person, other than the parties hereto and their successors
      hereunder, and the Noteholders, the Insurer, and any other party
      secured
      hereunder, and

      Holidays.
      In any
      case where the date on which any payment isdue

      A
      Notes
      or this
      Indenture) payment need not be made on such date, but may be made on the next
      succeeding Business Day with the same force and effect as if made on the date
      on
      which nominally
      due, and no interest shall accrue for
      the
      period from
      and
      after any such nominal date.

     

    Section
      11.13 GOVERNING
      LAW.
      THIS
      INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW

      may be
      executed in any number of
      counterparts, each of which so executed shall be deemed to be an original,
      but
      all such counterparts shall together constitute but one and the same
      instrument.

     

    Section
      11.15 Recording
      of Indenture.
      If this
      Indenture is subject to recording
      in any
      appropriate public recording offices, such recording is to be effected by the
      Issuer and at its expense
      accompanied by an Opinion of Counsel (which may be counsel to the Indenture
      Trustee
      or any
      other counsel reasonably acceptable to the Indenture Trustee) to the effect
      that
      such recording is necessary either for the protection of the Noteholders, the

      secured
      hereunder or for the enforcement of any right
      or
      remedy granted to the Indenture
