                                       6

                                  ARTICLE III

               POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

     SECTION 3.1 Powers and Duties of the Guarantee Trustee.

          (a)    This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders,  and the  Guarantee  Trustee  shall not transfer
this  Guarantee  Agreement to any Person except a Holder  exercising  its rights
pursuant to Section 5.4(d) or to a Successor  Guarantee  Trustee upon acceptance
by such  Successor  Guarantee  Trustee of its  appointment  to act as  Successor
Guarantee Trustee.  The right, title and interest of the Guarantee Trustee shall
automatically vest in any Successor  Guarantee Trustee,  upon acceptance by such
Successor Guarantee Trustee of its appointment  hereunder,  and such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been  executed  and  delivered  pursuant to the  appointment  of such  Successor
Guarantee Trustee.

          (b)    The rights, immunities,  duties  and  responsibilities  of  the
Guarantee  Trustee  shall be as provided by this  Guarantee  Agreement and there
shall be no other duties or  obligations,  express or implied,  of the Guarantee
Trustee.   Notwithstanding  the  foregoing,  no  provisions  of  this  Guarantee
Agreement shall require the Guarantee Trustee to expend or risk its own funds or
otherwise incur any 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  for  believing  that  repayment  of such funds or  adequate
indemnity  against  such risk or  liability  is not  reasonably  assured  to it.

                                       7


Whether or not herein  expressly so provided,  every provision of this Guarantee
Agreement  relating to the conduct or  affecting  the  liability of or affording
protection to the Guarantee  Trustee shall be subject to the  provisions of this
Section 3.1. To the extent that, at law or in equity,  the Guarantee Trustee has
duties and liabilities  relating to the Guarantor or the Holders,  the Guarantee
Trustee shall not be liable to any Holder for the Guarantee Trustee's good faith
reliance on the provisions of this Guarantee  Agreement.  The provisions of this
Guarantee Agreement, to the extent that they restrict the duties and liabilities
of the Guarantee Trustee otherwise  existing at law or in equity,  are agreed by
the  Guarantor and the Holders to replace such other duties and  liabilities  of
the Guarantee Trustee.

          (c)    No provision of this Guarantee  Agreement shall be construed to
relieve the  Guarantee  Trustee from  liability  for its own  negligent  action,
negligent failure to act or own willful misconduct, except that:

               (i)  the  Guarantee  Trustee shall not be liable for any error of
     judgment  made in good  faith by a  Responsible  Officer  of the  Guarantee
     Trustee, unless it shall be proved that the Guarantee Trustee was negligent
     in ascertaining the pertinent facts upon which such judgment was made; and

               (ii) the  Guarantee  Trustee  shall not be liable with respect to
     any action  taken or omitted to be taken by it in good faith in  accordance
     with  the  direction  of  the  Holders  of not  less  than  a  Majority  in
     Liquidation Amount of the Preferred Securities relating to the time, method
     and place of  conducting  any  proceeding  for any remedy  available to the
     Guarantee  Trustee,  or exercising  any trust or power  conferred  upon the
     Guarantee Trustee under this Guarantee Agreement.

     SECTION 3.2 Certain Rights of the Guarantee Trustee.

          (a)    Subject to the provisions of Section 3.1:

               (i)  the  Guarantee  Trustee may  conclusively  rely and shall be
     fully  protected in acting or  refraining  from acting in good faith and in
     accordance  with  the  terms  hereof  upon  any  resolution,   certificate,
     statement,   instrument,   opinion,  report,  notice,  request,  direction,
     consent,  order, bond,  debenture,  note, other evidence of indebtedness or
     other paper or document reasonably believed by it to be genuine and to have
     been signed, sent or presented by the proper party or parties;

               (ii) any direction or act of the Guarantor  contemplated  by this
     Guarantee  Agreement  shall  be  sufficiently  evidenced  by  an  Officers'
     Certificate unless otherwise prescribed herein;

               (iii) the  Guarantee  Trustee may consult with  counsel,  and the
     advice  of such  counsel  shall  be full  and  complete  authorization  and
     protection in respect of any action taken,  suffered or omitted to be taken

                                       8


     by it  hereunder  in good faith and in reliance  thereon and in  accordance
     with such advice. Such counsel may be counsel to the Guarantee Trustee, the
     Guarantor or any of its  Affiliates  and may be one of its  employees.  The
     Guarantee  Trustee  shall  have the right at any time to seek  instructions
     concerning the administration of this Guarantee Agreement from any court of
     competent jurisdiction;

               (iv) the  Guarantee  Trustee  shall  be under  no  obligation  to
     exercise  any of the  rights  or  powers  vested  in it by  this  Guarantee
     Agreement  at the request or  direction  of any Holder,  unless such Holder
     shall  have  provided  to the  Guarantee  Trustee  reasonable  security  or
     indemnity against the costs, expenses (including reasonable attorneys' fees
     and  expenses)  and  liabilities  that might be incurred by it in complying
     with such request or direction,  including such reasonable  advances as may
     be requested by the Guarantee Trustee; provided, that, nothing contained in
     this Section  3.2(a)(iv)  shall be taken to relieve the Guarantee  Trustee,
     upon the  occurrence of an Event of Default,  of its obligation to exercise
     the rights and powers vested in it by this Guarantee Agreement;

     direction,  consent,  order,  bond,  debenture,  note,  other  evidence  of
     indebtedness or other paper or document,  but the Guarantee Trustee, in its
     discretion,  may make such further inquiry or investigation into such facts
     or matters as it may see fit, and if the Guarantee  Trustee shall determine
     to make such inquiry or investigation,  it shall be entitled to examine the
     books,  records and premises of the  Guarantor,  personally  or by agent or
     attorney;

               (vi) the  Guarantee  Trustee  may  execute  any of the  trusts or
     powers  hereunder or perform any duties  hereunder either directly or by or
     through its agents,  attorneys,  custodians  or nominees and the  Guarantee
     Trustee shall not be  responsible  for any  misconduct or negligence on the
     part of any such agent,  attorney,  custodian or nominee appointed with due
     care by it hereunder;

               (vii) whenever in the administration of this Guarantee  Agreement
     the Guarantee Trustee shall deem it desirable to receive  instructions with

     (A) may request  instructions from the Holders of a Majority in Liquidation

     Agreement;

               (ix) whenever, in the administration of this Guarantee Agreement,
     the Guarantee  Trustee  shall deem it desirable  that a matter be proved or
     established  before  taking,  suffering  or  omitting  to take  any  action
     hereunder,   the  Guarantee   Trustee  (unless  other  evidence  is  herein
     specifically  prescribed)  may,  in the  absence  of bad faith on its part,

impose any duty or  obligation  on the  Guarantee  Trustee to perform any act or
acts or exercise any right, power, duty or obligation conferred or imposed on it
in any  jurisdiction  in which it shall be  illegal,  or in which the  Guarantee
Trustee shall be unqualified or incompetent in accordance  with  applicable law,
to perform any such act or acts or to exercise  any such right,  power,  duty or
obligation.  No permissive power or authority available to the Guarantee Trustee
shall  be  construed  to be a duty to act in  accordance  with  such  power  and
authority.

     SECTION 3.3 Compensation.

     The  Guarantor  agrees to pay to the  Guarantee  Trustee  from time to time
reasonable  compensation  for  all  services  rendered  by it  hereunder  (which

compensation  of a trustee of an express  trust) and to reimburse  the Guarantee

     SECTION 4.1 Guarantee Trustee; Eligibility.

          (a) There shall at all times be a Guarantee Trustee which shall:

               (i) not be an Affiliate of the Guarantor; and

          corporation  shall be deemed to be its combined capital and surplus as
          set forth in its most recent report of condition so published.

          (b)    If at any time the Guarantee Trustee shall cease to be eligible
     to so act under Section  4.1(a),  the Guarantee  Trustee shall  immediately
     resign in the manner and with the effect set out in Section 4.2(c).

          (c)    If the Guarantee Trustee has or shall acquire any  "conflicting

     manner and with the effect set out in Section 4.2(c).

                                       11


     SECTION 4.2 Appointment, Removal and Resignation of the Guarantee Trustee.

          (a)    Subject  to  Section  4.2(b),  the  Guarantee  Trustee  may  be
     appointed or removed  without  cause at any time by the  Guarantor,  except
     during an Event of Default.

          (b)    The Guarantee Trustee shall not be  removed  until a  Successor
     Guarantee  Trustee has been appointed and has accepted such  appointment by
     written  instrument  executed  by  such  Successor  Guarantee  Trustee  and
     delivered to the Guarantor.

          (c)    The  Guarantee  Trustee  appointed  hereunder shall hold office
     until a Successor  Guarantee Trustee shall have been appointed or until its
     removal or  resignation.  The  Guarantee  Trustee  may resign  from  office
     (without  need for prior or  subsequent  accounting)  by an  instrument  in
     writing  executed by the Guarantee  Trustee and delivered to the Guarantor,
     which resignation shall not take effect until a Successor Guarantee Trustee
     has been  appointed  and has accepted  such  appointment  by  instrument in
     writing executed by such Successor  Guarantee  Trustee and delivered to the
     Guarantor and the resigning Guarantee Trustee.

          (d)    If no Successor Guarantee Trustee shall have been appointed and
     accepted  appointment  as provided in this  Section 4.2 within  thirty (30)
     days after delivery to the Guarantor of an instrument of  resignation,  the
     resigning Guarantee Trustee may petition,  at the expense of the Guarantor,
     any  court  of  competent  jurisdiction  for  appointment  of  a  Successor
     Guarantee Trustee. Such court may thereupon, after prescribing such notice,
     if any, as it may deem proper, appoint a Successor Guarantee Trustee.

     theretofore  paid  by or on  behalf  of  the  Issuer),  as  and  when  due,
     regardless  of any  defense  (except  for the  defense  of  payment  by the
     Issuer),  right of  set-off  or  counterclaim  which the Issuer may have or
     assert.  The  Guarantor's  obligation  to make a  Guarantee  Payment may be

                                       12


     Holders or by causing the Issuer to pay such  amounts to the  Holders.  The

     event it makes any direct payment to the Holders hereunder.

          (b)    The  Guarantor  hereby  also   agrees to  assume  any  and  all
     Obligations of the Issuer,  and, in the event any such Obligation is not so
     assumed,  subject to the terms and conditions  hereof, the Guarantor hereby
     irrevocably  and  unconditionally  guarantees to each  Beneficiary the full
     payment, when and as due, of any and all Obligations to such Beneficiaries.
     This  Guarantee is intended to be for the  Beneficiaries  who have received
     notice hereof.

     SECTION 5.2 Waiver of Notice and Demand.

     The Guarantor hereby waives notice of acceptance of the Guarantee Agreement

     performance  or  observance  by  the  Issuer  of  any  express  or  implied
     agreement, covenant, term or condition relating to the Preferred Securities
     to be performed or observed by the Issuer;

          (b)    the  extension  of time for the payment by the Issuer of all or
     any  portion of the  Distributions  (other  than an  extension  of time for
     payment of  Distributions  that results from the  extension of any interest
     payment  period  on the Notes as  provided  in the  Indenture),  Redemption
     Price,  Liquidation  Distribution or any other sums payable under the terms
     of the Preferred Securities or the extension of time for the performance of

          (c)    any  failure, omission,  delay or lack of diligence on the part
     of the Holders to enforce, assert or exercise any right,  privilege,  power
     or remedy  conferred on the Holders  pursuant to the terms of the Preferred
     Securities,  or any action on the part of the Issuer granting indulgence or
     extension of any kind;

          (d)    the voluntary  or involuntary liquidation, dissolution, sale of
     any collateral,  receivership,  insolvency,  bankruptcy, assignment for the
     benefit  of  creditors,   reorganization,   arrangement,   composition   or
     readjustment of debt of, or other similar proceedings affecting, the Issuer
     or any of the assets of the Issuer;

                                       13


          (e)    any invalidity of, or defect or deficiency  in,  the  Preferred

          (f)    the  settlement  or  compromise  of  any  obligation guaranteed
     hereby or hereby incurred; or

          (g)    any  other  circumstance   whatsoever  that    might  otherwise
     constitute  a legal or equitable  discharge  or defense of a guarantor,  it
     being the intent of this Section 5.3 that the  obligations of the Guarantor
     hereunder   shall  be  absolute  and   unconditional   under  any  and  all
     circumstances.

     There  shall be no  obligation  of the Holders to give notice to, or obtain
the  consent  of, the  Guarantor  with  respect to the  happening  of any of the
foregoing.

     SECTION 5.4 Rights of Holders.

     The Guarantor  expressly  acknowledges  that: (a) this Guarantee  Agreement
will be deposited  with the Guarantee  Trustee to be held for the benefit of the

Trustee in respect of this Guarantee  Agreement or exercising any trust or power
conferred upon the Guarantee Trustee under this Guarantee Agreement; and (d) any
Holder may  institute  a legal  proceeding  directly  against the  Guarantor  to
enforce its rights under this Guarantee  Agreement,  without first instituting a
legal proceeding against the Guarantee Trustee, the Issuer or any other Person.

     SECTION 5.5 Guarantee of Payment.

     This  Guarantee  Agreement  creates  a  guarantee  of  payment  and  not of
collection. This Guarantee Agreement will not be discharged except by payment of
the Guarantee Payments in full (without  duplication of amounts theretofore paid
by the Issuer) or upon distribution of Notes to Holders as provided in the Trust
Agreement.

     SECTION 5.6 Subrogation.

     The  Guarantor  shall be  subrogated  to all (if any) rights of the Holders
against  the  Issuer  in  respect  of any  amounts  paid to the  Holders  by the
Guarantor  under  this  Guarantee  Agreement  and shall  have the right to waive
payment by the Issuer  pursuant to Section 5.1;  provided,  that,  the Guarantor
shall not (except to the extent  required  by  mandatory  provisions  of law) be
entitled to enforce or exercise any rights it may acquire by way of  subrogation
or any indemnity,  reimbursement or other agreement, in all cases as a result of
payment under this Guarantee Agreement, if, at the time of any such payment, any
amounts are due and unpaid under this Guarantee  Agreement.  If any amount shall
be paid to the Guarantor in violation of the preceding  sentence,  the Guarantor
agrees to hold such  amount in trust for the Holders and to pay over such amount

     SECTION 5.7 Independent Obligations.

     The Guarantor  acknowledges that its obligations  hereunder are independent
of the  obligations  of the Issuer with respect to the Preferred  Securities and
that the Guarantor shall be liable as principal and as debtor  hereunder to make
Guarantee   Payments   pursuant  to  the  terms  of  this  Guarantee   Agreement
notwithstanding  the  occurrence  of any event  referred to in  subsections  (a)
through (g), inclusive, of Section 5.3.

     SECTION 5.8 Enforcement.

     A Beneficiary  may enforce the  Obligations  of the Guarantor  contained in

right or remedy to require that any action be brought  against the Issuer or any
other person or entity before proceeding against the Guarantor.

                                   ARTICLE VI

                           COVENANTS AND SUBORDINATION

     SECTION 6.1 Dividends, Distributions and Payments.

     So long as any Preferred Securities remain outstanding, if there shall have
occurred  and be  continuing  an Event of  Default or the  Guarantor  shall have
entered  into an  Extension  Period as provided  for in the  Indenture  and such
period, or any extension thereof,  shall have commenced and be continuing,  then
the Guarantor may not (a) declare or pay any dividends or  distributions  on, or
redeem, purchase,  acquire or make a liquidation payment with respect to, any of
the  Guarantor's  Equity  Interests (as defined in the  Indenture),  (b) vote in
favor of or permit or otherwise allow any of its Subsidiaries (as defined in the
Indenture)  to  declare or pay any  dividends  or  distributions  on, or redeem,
purchase,  acquire or make a  liquidation  payment  with respect to or otherwise
retire, any of such Subsidiary's  Equity Interests entitling the holders thereof
to a stated  rate of return  other than  dividends  or  distributions  on Equity
Interests payable to the Guarantor or any Subsidiary  thereof (for the avoidance
of doubt, whether such Equity Interests are perpetual or otherwise), or (c) make
any payment of principal  of or any interest or premium on or repay,  repurchase
or redeem  any debt  securities  of the  Guarantor  that rank pari  passu in all
respects with or junior in interest to the junior  subordinated  notes issued by
the Guarantor pursuant to the Indenture (other than (i) repurchases, redemptions
or other  acquisitions  of Equity  Interests of the Guarantor in connection with
(1) any employment  contract,  benefit plan or other similar arrangement with or
for  the  benefit  of  any  one  or  more  employees,   officers,  directors  or
consultants,  (2) a dividend  reinvestment  or  stockholder  stock  purchase  or
similar plan with respect to any Equity  Interests or (3) the issuance of Equity
Interests of the Guarantor (or securities  convertible  into or exercisable  for
such Equity  Interests) as consideration in an acquisition  transaction  entered
into  prior  to the  occurrence  of such  Event  of  Default  or the  applicable
Extension Period,  (ii) as a result of an exchange or conversion of any class or
series  of the  Guarantor's  Equity  Interests  (or any  Equity  Interests  of a
Subsidiary of the Guarantor) for any class or series of the  Guarantor's  Equity

                                       15



Interests or any class of series of the Guarantor's  indebtedness  for any class
or series of the Guarantor's Equity Interests,  (iii) the purchase of fractional
interests in Equity  Interests of the  Guarantor  pursuant to the  conversion or
exchange  provisions of such Equity Interests or the security being converted or
exchanged,  (iv) any  declaration  of a dividend in  connection  with any rights
plan,  the  issuance of rights,  Equity  Interests or other  property  under any
rights plan or the redemption or repurchase of rights pursuant  thereto,  or (v)
any dividend in the form of Equity Interests,  warrants, options or other rights
where the  dividend  Equity  Interests  or the Equity  Interests  issuable  upon
exercise of such warrants, options or other rights are the same Equity Interests
as those on which the  dividend  is being paid or rank pari passu with or junior
to such Equity Interests).

     SECTION 6.2 Subordination.

     The  obligations  of the  Guarantor  under this  Guarantee  Agreement  will
constitute unsecured  obligations of the Guarantor and will rank subordinate and
junior in right of payment to all Senior Debt of the Guarantor.

     SECTION 6.3 Pari Passu Guarantees.

          (a)    The obligations of the Guarantor under this Guarantee Agreement
     shall rank pari  passu  with the  obligations  of the  Guarantor  under any
     similar  guarantee  agreements  issued by the  Guarantor  with  respect  to
     preferred securities (if any) similar to the Preferred  Securities,  issued
     by trusts other than the Issuer  established  or to be  established  by the
     Guarantor (if any), in each case similar to the Issuer, including,  without
     limitation,  the Guarantee  Agreement,  dated June 26, 2002,  issued by the
     Guarantor  with  respect to the  preferred  securities  issued by  Temecula
     Valley  Statutory  Trust I, the Guarantee  Agreement,  dated  September 17,
     2003,  issued by the  Guarantor  with respect to the  preferred  securities
     issued by Temecula  Valley  Statutory  Trust II, the  Guarantee  Agreement,
     dated  September  20,  2004,  issued by the  Guarantor  with respect to the
     preferred  securities issued by Temecula Valley Statutory Trust III and the
     Guarantee Agreement, dated September 29, 2005, issued by the Guarantor with
     respect to the preferred  securities  issued by Temecula  Valley  Statutory
     Trust IV.

          (b)    The right  of the Guarantor to participate in any  distribution
     of assets of any of its subsidiaries upon any such subsidiary's liquidation
     or  reorganization or otherwise is subject to the prior claims of creditors
     of that  subsidiary,  except to the  extent  the  Guarantor  may  itself be
     recognized as a creditor of that subsidiary.  Accordingly,  the Guarantor's
     obligations  under this Guarantee will be effectively  subordinated  to all
     existing  and  future  liabilities  of the  Guarantor's  subsidiaries,  and
     claimants  should  look only to the assets of the  Guarantor  for  payments
     hereunder.  This  Guarantee  does not limit the  incurrence  or issuance of
     other secured or unsecured debt of the Guarantor,  including Senior Debt of
     the  Guarantor,  under any  indenture or agreement  that the  Guarantor may
     enter into in the future or otherwise.

the  Preferred  Securities  or (c)  full  payment  of  the  amounts  payable  in
accordance   with  the  Trust   Agreement   upon   liquidation  of  the  Issuer.
Notwithstanding  the  foregoing,  this  Guarantee  Agreement will continue to be
effective or will be  reinstated,  as the case may be, if at any time any Holder
must restore  payment of any sums paid with respect to Preferred  Securities  or
this Guarantee  Agreement.  The  obligations of the Guarantor under Sections 3.3
and 3.4 shall survive any such termination or the resignation and removal of the
Guarantee Trustee.
