         before the giving of such notice, provided, that, the Preferred
         Guarantee Trustee shall be protected in withholding such notice if and
         so long as a Responsible Officer of the Preferred Guarantee Trustee in
         good faith determines that the withholding of such notice is in the
         interests of the Holders of the Preferred Securities.

              (b) The Preferred Guarantee Trustee shall not be deemed to have

                           PREFERRED GUARANTEE TRUSTEE

         .1. POWERS AND DUTIES OF THE PREFERRED GUARANTEE TRUSTEE.

              (a) This Preferred Securities Guarantee shall be held by the
         Preferred Guarantee Trustee for the benefit of the Holders of the
         Preferred Securities, and the Preferred Guarantee Trustee shall not
         transfer this Preferred Securities Guarantee to any Person except a
         Holder of Preferred Securities exercising such Holder's rights pursuant
         to Section 5.04(b) or to a Successor Preferred Guarantee Trustee on
         acceptance by such Successor Preferred Guarantee Trustee of its
         appointment to act as Successor Preferred Guarantee Trustee. The right,
         title and interest of the Preferred Guarantee Trustee shall




                                       6
   9

         automatically vest in any Successor Preferred Guarantee Trustee, 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 Preferred Guarantee Trustee.

              (b) If an Event of Default actually known to a Responsible Officer
         of the Preferred Guarantee Trustee has occurred and is continuing, the
         Preferred Guarantee Trustee shall enforce this Preferred Securities
         Guarantee for the benefit of the Holders of the Preferred Securities.

              (c) The Preferred Guarantee Trustee, before the occurrence of any
         Event of Default and after the curing of all Events of Default that may
         have occurred, shall undertake to perform only such duties as are
         specifically set forth in this Preferred Securities Guarantee, and no
         implied covenants shall be read into this Preferred Securities
         Guarantee against the Preferred Guarantee Trustee. In case an Event of
         Default has occurred (that has not been cured or waived pursuant to
         Section 2.06) and is actually known to a Responsible Officer of the
         Preferred Guarantee Trustee, the Preferred Guarantee Trustee shall
         exercise such of the rights and powers vested in it by this Preferred
         Securities Guarantee, and use the same degree of care and skill in its
         exercise thereof, as a prudent person would exercise or use under the
         circumstances in the conduct of such person's own affairs.

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

                   (i) prior to the occurrence of any Event of Default and after
              the curing or waiving of all such Events of Default that may have
              occurred:

                        (A) the duties and obligations of the Preferred
                   Guarantee Trustee shall be determined solely by the express
                   provisions of this Preferred Securities Guarantee, and the
                   Preferred Guarantee Trustee shall not be liable except for
                   the performance of such duties and obligations as are
                   specifically set forth in this Preferred Securities
                   Guarantee, and no implied covenants or obligations shall be
                   read into this Preferred Securities Guarantee against the
                   Preferred Guarantee Trustee; and

                        (B) in the absence of bad faith on the part of the
                   Preferred Guarantee Trustee, the Preferred Guarantee Trustee
                   may conclusively rely, as to the truth of the statements and
                   the correctness of the opinions expressed therein, upon any
                   certificates or opinions furnished to the Preferred Guarantee
                   Trustee and conforming to the requirements of this Preferred
                   Securities Guarantee; but in the case of any such
                   certificates or opinions that by any provision hereof are
                   specifically required to be furnished to the Preferred
                   Guarantee Trustee, the Preferred Guarantee Trustee shall be
                   under a duty to examine the same to determine whether or

   10

                   not they conform to the requirements of this Preferred
                   Securities Guarantee;

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

                   (iii) the Preferred 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 Preferred Guarantee
              Trustee, or exercising any trust or power conferred upon the
              Preferred Guarantee Trustee under this Preferred Securities
              Guarantee; and

                   (iv) no provision of this Preferred Securities Guarantee
              shall require the Preferred Guarantee Trustee to expend or risk
              its own funds or otherwise incur personal financial liability in
              the performance of any of its duties or in the exercise of any of
              its rights or powers if the Preferred Guarantee Trustee shall have
              reasonable grounds for believing that the repayment of such funds
              or liability is not reasonably assured to it under the terms of
              this Preferred Securities Guarantee or indemnity, reasonably
              satisfactory to the Preferred Guarantee Trustee, against such risk
              or liability is not reasonably assured to it.

         .2. CERTAIN RIGHTS OF PREFERRED GUARANTEE TRUSTEE.

              acting upon, any resolution, certificate, statement, instrument,
              opinion, report, notice, request, direction, consent, order, bond,
              debenture, note, other evidence of indebtedness or other paper or

              Securities Guarantee, the Preferred Guarantee Trustee shall deem
              it desirable that a matter be proved or established before taking,
              suffering or omitting any action hereunder, the Preferred
              Guarantee Trustee (unless other evidence is herein specifically
              prescribed) may, in the absence of bad faith on its part, request
              and conclusively rely upon an Officers' Certificate which, upon
              receipt of such request, shall be promptly delivered by the
              Guarantor.

                   (iv) The Preferred Guarantee Trustee shall have no duty to
              see to any recording, filing or registration of any instrument (or
              any re-recording, re-filing or registration thereof).

                   (v) The Preferred Guarantee Trustee may consult with counsel,
              and the written advice or opinion of such counsel with respect to
              legal matters shall be full and complete authorization and
              protection in respect of any action taken, suffered or omitted by
              it hereunder in good faith and in accordance with such advice or
              opinion. Such counsel may be counsel to the Guarantor or any of
              its Affiliates and may include any of its employees. The Preferred
              Guarantee Trustee shall have the right at any time to seek
              instructions concerning the administration of this Preferred
              Securities Guarantee from any court of competent jurisdiction.

                   (vi) The Preferred Guarantee Trustee shall be under no
              obligation to exercise any of the rights or powers vested in it by
              this Preferred Securities Guarantee at the request or direction of
              any Holder, unless such Holder shall have provided to the
              Preferred Guarantee Trustee such security and indemnity,
              reasonably satisfactory to the Preferred Guarantee Trustee,
              against the costs, expenses (including attorneys' fees and
              expenses and the expenses of the Preferred Guarantee Trustee's
              agents, nominees or custodians) 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
              Preferred Guarantee Trustee; provided that, nothing contained in
              this Section 3.02(a)(vi) shall be taken to relieve the Preferred
              Guarantee Trustee, upon the occurrence of an Event of Default, of
              its obligation to exercise the rights and powers vested in it by
              this Preferred Securities Guarantee.

                   (vii) The Preferred Guarantee 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, direction, consent, order, bond, debenture, note,
              other evidence of indebtedness or other paper or document, but the
              Preferred Guarantee Trustee, in its discretion, may make such
              further inquiry or investigation into such facts or matters as it
              may see fit.

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

                   (ix) Any action taken by the Preferred Guarantee Trustee or
              its agents hereunder shall bind the Holders of the Preferred
              Securities, and the signature of the Preferred Guarantee Trustee
              or its agents alone shall be sufficient and effective to perform
              any such action. No third party shall be required to inquire as to
              the authority of the Preferred Guarantee Trustee to so act or as
              to its compliance with any of the terms and provisions of this
              Preferred Securities Guarantee, both of




                                       9
   12


              which shall be conclusively evidenced by the Preferred Guarantee
              Trustee's or its agent's taking such action.

                   (x) Whenever in the administration of this Preferred
              Securities Guarantee the Preferred Guarantee Trustee shall deem it
              desirable to receive instructions with respect to enforcing any
              remedy or right or taking any other action hereunder, the
              Preferred Guarantee Trustee (A) may request instructions from the
              Holders of a Majority in liquidation amount of the Preferred
              Securities, (B) may refrain from enforcing such remedy or right or
              taking such other action until such instructions are received, and
              (C) shall be protected in conclusively relying on or acting in
              accordance with such instructions.

              (b) No provision of this Preferred Securities Guarantee shall be
         deemed to impose any duty or obligation on the Preferred 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 Preferred 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
         Preferred Guarantee Trustee shall be construed to be a duty.

         .3. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF GUARANTEE. The recitals
contained in this Preferred Securities Guarantee shall be taken as the
statements of the Guarantor, and the Preferred Guarantee Trustee does not assume
any responsibility for their correctness. The Preferred Guarantee Trustee makes

Guarantee.

         .4. COMPENSATION AND REIMBURSEMENT. The Guarantor covenants and agrees
to pay to the Preferred Guarantor Trustee, and the Preferred Guarantor Trustee
shall be entitled to, such reasonable compensation (which shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust), as the Guarantor and the Preferred Guarantor Trustee may from time to
time agree in writing, for all services rendered by it in the execution of the
trusts hereby created and in the exercise and performance of any of the powers
and duties hereunder of the Preferred Guarantee Trustee, and, except as
otherwise expressly provided herein, the Guarantor will pay or reimburse the
Preferred Guarantor Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Preferred Guarantor Trustee
in accordance with any of the provisions of this Preferred Securities Guarantee
(including the reasonable compensation and the expenses and disbursements of its
counsel and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith. The
Guarantor also covenants to indemnify the Preferred Guarantor Trustee (and its
officers, agents, directors and employees) for, and to hold it harmless against,
any loss, liability or expense incurred without negligence or bad faith on the
part of the Preferred Guarantor Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the costs and expenses
of defending itself against any claims of liability in the premises.

                           PREFERRED GUARANTEE TRUSTEE

         .1. PREFERRED GUARANTEE TRUSTEE; ELIGIBILITY.

              combined capital and surplus of at least with respect to the
              initial Trustee $500,000 (and its principal parent holding company
              having a combined capital and surplus of at least $50,000,000) and
              with respect to any successor Trustee $50,000,000, and subject to
              supervision or examination by federal, state, territorial or
              District of Columbia authority. If such corporation publishes
              reports of condition at least annually, pursuant to law or to the
              requirements of the supervising or examining authority referred to
              above, then, for the purposes of this Section 4.01(a)(ii), the
              combined capital and surplus of such 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 Preferred Guarantee Trustee shall cease to
         be eligible to so act under Section 4.01(a), the Preferred Guarantee
         Trustee shall immediately resign in the manner and with the effect set
         out in Section 4.02(c).

              (c) If the Preferred Guarantee Trustee has or shall acquire any
         "conflicting interest" within the meaning of Section 310(b) of the
         Trust Indenture Act, the Preferred Guarantee Trustee and Guarantor
         shall in all respects comply with the provisions of Section 310(b) of
         the Trust Indenture Act.

         .2. APPOINTMENT, REMOVAL AND RESIGNATION OF PREFERRED GUARANTEE
TRUSTEES.

              (a) Subject to Section 4.02(b), the Preferred Guarantee Trustee
         may be appointed or removed without cause at any time by the Guarantor.

              (b) The Preferred Guarantee Trustee shall not be removed in
         accordance with Section 4.02(a) until a Successor Preferred Guarantee
         Trustee has been appointed and has accepted such appointment by written
         instrument executed by such Successor Preferred Guarantee Trustee and
         delivered to the Guarantor.

              (c) The Preferred Guarantee Trustee appointed to office shall hold
         office until a Successor Preferred Guarantee Trustee shall have been
         appointed or until its removal or resignation. The Preferred Guarantee
         Trustee may resign from office (without need for





                                       11
   14


         prior or subsequent accounting) by an instrument in writing executed by
         the Preferred Guarantee Trustee and delivered to the Guarantor, which
         resignation shall not take effect until a Successor Preferred Guarantee
         Trustee has been appointed and has accepted such appointment by
         instrument in writing executed by such Successor Preferred Guarantee
         Trustee and delivered to the Guarantor and the resigning Preferred
         Guarantee Trustee.

              (d) If no Successor Preferred Guarantee Trustee shall have been
         appointed and accepted appointment as provided in this Section 4.02
         within 60 days after delivery to the Guarantor of an instrument of
         resignation, the resigning Preferred Guarantee Trustee may petition any
         court of competent jurisdiction for appointment of a Successor
         Preferred Guarantee Trustee. Such court may thereupon, after
         prescribing such notice, if any, as it may deem proper, appoint a
         Successor Preferred Guarantee Trustee.

              (e) No Preferred Guarantee Trustee shall be liable for the acts or
         omissions to act of any Successor Preferred Guarantee Trustee.

              (f) Upon termination of this Preferred Securities Guarantee or
         removal or resignation of the Preferred Guarantee Trustee pursuant to
         this Section 4.02, the Guarantor shall pay to the Preferred Guarantee
         Trustee all amounts accrued to the date of such termination, removal or
         resignation.

         .1. GUARANTEE. The Guarantor irrevocably and unconditionally agrees to
pay in full to the Holders the Guarantee Payments (without duplication of
amounts theretofore paid by Flagstar Trust), as and when due, regardless of any
defense, right of set-off or counterclaim that Flagstar Trust may have or
assert. The Guarantor's obligation to make a Guarantee Payment may be satisfied
by direct payment of the required amounts by the Guarantor to the Holders or by
causing Flagstar Trust to pay such amounts to the Holders.

         .2. WAIVER OF NOTICE AND DEMAND. The Guarantor hereby waives notice of
acceptance of this Preferred Securities Guarantee and of any liability to which
it applies or may apply, presentment, demand for payment, any right to require a
proceeding first against Flagstar Trust or any other Person before proceeding
against the Guarantor, protest, notice of nonpayment, notice of dishonor, notice
of redemption and all other notices and demands.

   15

              (b) the extension of time for the payment by Flagstar Trust of all
         or any portion of the Distributions, Redemption Price, Liquidation

         Securities or the extension of time for the performance of any other

         Securities (other than an extension of time for payment of
         Distributions, Redemption Price, Liquidation Distribution or other sum
         payable that results from the extension of any interest payment period
         on the Junior Subordinated Debentures or any extension of the maturity
         date of the Junior Subordinated Debentures permitted by the Indenture);

              (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 Flagstar Trust
         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,
         Flagstar Trust or any of the assets of Flagstar Trust;

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

              (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 5.03 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 consent of, the Guarantor with respect to the happening of any of the
foregoing.

         .4. RIGHTS OF HOLDERS.

              (a) The Holders of a Majority in liquidation amount of the

         place of conducting of any proceeding for any remedy available to the
         Preferred Guarantee Trustee in respect of this Preferred Securities
         Guarantee or exercising any trust or power conferred upon the Preferred
         Guarantee Trustee under this Preferred Securities Guarantee.

              (b) Any Holder of Preferred Securities may institute a legal
         proceeding directly against the Guarantor to enforce its rights under
         this Preferred Securities Guarantee, without first instituting a legal
         proceeding against Flagstar Trust, the Preferred Guarantee Trustee or
         any other Person.

         .5. GUARANTEE OF PAYMENT. This Preferred Securities Guarantee creates a
Guarantee of payment and not of collection.








                                       13
   16

         .6. SUBROGATION. The Guarantor shall be subrogated to all (if any)
rights of the Holders of Preferred Securities against Flagstar Trust in respect
of any amounts paid to such Holders by the Guarantor under this Preferred
Securities Guarantee; provided, however, that the Guarantor shall not (except to
the extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under this
Preferred Securities Guarantee, if, at the time of any such payment, any amounts
are due and unpaid under this Preferred Securities Guarantee. 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 to the Holders.

         .7. INDEPENDENT OBLIGATIONS. The Guarantor acknowledges that its
obligations hereunder are independent of the obligations of Flagstar Trust 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 Preferred Securities Guarantee notwithstanding the occurrence of
any event referred to in subsections (a) through (g), inclusive, of Section
5.03.

         .1. LIMITATION OF TRANSACTIONS. So long as any Preferred Securities
remain outstanding, if there shall have occurred and be continuing an Event of
Default or an event of default under the Trust Agreement, then (a) the Guarantor
shall not declare or pay any dividend or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of its capital
stock, (b) the Guarantor shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by
