1     Definitions

      1.1     Application means a request for coverage, including assumption
              of coverage, under this Policy for a Loan on a form or in a

              documents or information furnished to the Company by the Insured
              or any other Person in connection with the insuring of the Loan.
              An application will include information, if so furnished to the
              Company, contained in the Borrower's Loan application,
              appraisal, verifications of income and deposit, plans and
              specifications for the Property, and all other exhibits and
              documents, and will include all data and information so
              furnished by electronic means.

         1.2  Appropriate Proceedings means any legal or administrative
              action by the Insured affecting either a Loan or title to a
              Property, including:

              a.   Preserving a deficiency recovery by making a bid at the
                   foreclosure sale and pursuing a deficiency judgment until
                   the end of the Settlement Period, where appropriate and
                   permissible and where directed by the Company; or

              b.   Enforcing the terms of the Loan as allowed by the laws
                   where the Property is located; or

              c.   Acquiring Borrower's Title or Good and Merchantable Title
                   to the Property, as either may be required under this
                   Policy, but excluding such title as may be acquired by a
                   voluntary conveyance from the Borrower; or

              d.   Asserting the Insured's interest in the Property in a
                   Borrower's bankruptcy.

      1.3     Borrower means any Person legally obligated to repay the debt
              obligation created by a Loan, including any co-signer or
              guarantor of the Loan.

      1.4     Borrower's Title means such title to a Property as was vested in
              the Borrower at the time of a conveyance to the Insured arising
              out of or pursuant to a foreclosure of the Loan; provided,
              however, if the Insured so elects, the redemption period need
              not have expired. Borrower's Title in the Insured may be, but
              need not be the equivalent of Good and Merchantable Title, and
              the deed evidencing Borrower's Title need not be recorded unless
              required by applicable law.

      1.5     Certificate means the document, which may be on the same form as
              the Commitment, issued by the Company pursuant to this Policy
              and extending the coverage indicated therein to a specified
              Loan.

      1.6     Certificate Effective Date means, as specified in the
              Certificate, (a) the closing date of a Loan, or (b) the later
              date requested by the Insured and accepted by the Company.

      1.7     Claim means the timely filed written request, made on a form or
              in a format provided or approved by the Company, to receive the
              benefits of this Policy.

      1.8     Claim Amount means the amount calculated in accordance with
              Section 6.2 of this Policy.

      1.9     Commitment means the document, which may be on the same form as
              the Certificate, issued by the Company evidencing the Company's
              offer to insure the Loan identified therein, subject to the
              terms and conditions therein and in this Policy.

      1.10    Default means the failure by a Borrower (a) to pay when due an
              amount equal to or greater than one (1) monthly regular periodic
              payment due under the terms of a Loan or (b) to pay all amounts
              due on acceleration of the Loan by the Insured after breach by
              the Borrower of a due on sale provision in the Loan, granting
              the Insured the right to accelerate the Loan upon transfer of
              title to, or an interest in, the Property and to institute
              Appropriate Proceedings. Violation by the Borrower of any other
              term or condition of the Loan which is a basis for Appropriate
              Proceedings shall not be considered to be a Default.

              A Loan is deemed to be in Default for that month as of the close
              of business on the installment due date for which a scheduled
              monthly payment has not been made or as of the close of business
              on the due date stated in the notice of acceleration given
              pursuant to the due-on-sale provision in the Loan. The Loan will
              be considered to remain in Default until filing of a Claim so
              long as such periodic payment has not been made or such basis
              for Appropriate Proceedings remains. For example, a Loan is
              "four (4) months in Default" if the monthly installments due on
              January 1 through April 1 remain unpaid as of the close of
              business on April 1 or if a basis for acceleration and
              Appropriate Proceedings exists for a continuous period of four
              months.

      1.11    Environmental Condition means the presence of environmental
              contamination, including nuclear reaction or radioactive waste,
              toxic waste, or poisoning, contamination or pollution of earth
              or water subjacent to the Property or of the atmosphere above
              the Property; or the presence, on or under a Property, of any
              "Hazardous Substance" as that term is defined by the federal
              Comprehensive Environmental Response, Compensation, and
              Liability Act (42 U.S.C. Sec. 9601 et. seq., as amended from
              time to time) or as defined by any similar state law, or of any
              "Hazardous Waste" or "Regulated Substance" as those terms are
              defined by the federal Resource Conservation and Recovery Act
              (42 U.S.C. sec. 6901, et seq., as amended from time to time) or
              as defined by any similar state law. Environmental Condition
              does not mean the presence of radon, lead paint, or asbestos.

      1.12    Good and Merchantable Title means title to a Property free and
              clear of all liens, encumbrances, covenants, conditions,
              restrictions, easements and rights of redemption, except for any
              of the following or as permitted in writing by the Company:

         a.   Any lien established by public bond, assessment or tax, when no
              installment, call or payment of or under such bond, assessment
              or tax is delinquent;

         b.   Any municipal and zoning ordinances and exceptions to title
              waived by the regulations of federal mortgage insurers and
              guarantors with respect to mortgages on one-to-four family
              residences in effect on the date on which the Loan was closed
              and all documents were executed; and

         c.   Any other impediments which will not have a materially adverse
              effect on either the transferability of the Property or the
              sale thereof to a bona fide purchaser.

              Good and Merchantable Title will not exist if (i) there is any
              lien pursuant to the Comprehensive Environmental Response,
              Compensation, and Liability Act, or similar federal or state
              law, as in effect from time to time, providing for liens in
              connection with the removal and clean-up of environmental
              conditions, or if notice has been given of commencement of
              proceedings which could result in such a lien, or (ii) there
              are limitations on ingress and egress to the Property or on use
              of utilities. Any action or proceeding after a foreclosure sale
              relating to establishing a deficiency judgment will not be
              considered in determining whether the Insured has acquired Good
              and Merchantable Title.

      1.13    Insured means:

              a.   The Person designated on the face of this Policy; or

                   a change in the Insured named on a Certificate in

              or charge on a Property and which the Company has approved for
              insurance and to which coverage under this Policy has been
              extended.

              for payment of a Perfected Claim which is calculated in

              occurred when a Default on a Loan occurs, even though the amount
              of Loss is not then either presently ascertainable or due and
              payable.

      1.16    Owner or Owner of the Loan means the Person who owns a Loan and

              association or other entity.

      1.19    Physical Damage means any tangible injury to a Property, whether

              riot, vandalism or any Environmental Condition.

      1.20    Policy means this contract of insurance and all Applications,

              Loan (or on behalf of the Owner's designee, if any) to service
              the Loan and of whom the Company has been notified. The Servicer
              acts as a representative of the Owner of the Loan (and the
              Owner's designee, if any) and will bind the Owner and its
              designee for all purposes of this Policy, including providing

              under Section 6.4, at the end of which a Loss is payable by the

      plural, masculine or feminine, as the case may be.

2     Obtaining Coverage and Payment of Premiums

      2.1     Application and Certificate -- In order to insure a Loan under
              this Policy, the Insured or a Person acting on behalf of the
              Insured must submit to the Company a properly completed
              Application. Approval of any Application will be at the
              discretion of the Company and will be in the form of a
              Commitment or a Certificate which offers to extend, or extends
              coverage under the terms and conditions of both this Policy and
              the Commitment or Certificate, as the case may be.

              In lieu of such an Application and supporting statements,
              documents and information submitted to the Company in connection
              with insuring a Loan, the Company may accept an alternative form
              of Application, containing more limited information, including
              certifications by or on behalf of the Insured as to
              characteristics of a Loan in lieu of supporting statements,
              documents and information. The Company shall be entitled to
              fully rely on such alternative Application as submitted. Use of
              an alternative form of Application shall not waive or change the
              other terms and conditions of this Policy under which a Loan is
              insured or the responsibility of the Insured for the accuracy of
              statements, documents and information submitted by it or other
              Persons to the Company as provided in this Policy.

              If the Company declines to approve a mortgage loan, it will not
              issue a Commitment or Certificate, and it will notify the
              Insured in writing of such declination. If the Insured or the
              Person acting on its behalf subsequently denies the mortgage
              loan application which it received from the applicant, the
              Insured or such Person will be responsible for notifying the
              applicant that the Company declined to approve the mortgage
              loan. Such notification will be made in compliance with any
              applicable state or federal laws or regulations, including the
              Equal Credit Opportunity Act and any other similar law or
              regulation.

      2.2     Representations of the Insured  --  The Insured represents that:

              a.   all statements made and information provided to the Company
                   in an Application or in any Commitment or Certificate
                   (including as such is related to continuation of coverage
                   upon assumption of a Loan), whether by it, the Borrower, or
                   any other Person, have been made and presented for and on
                   behalf of the Insured; and

              b.   such statements and information are not false or misleading
                   in any material respect as of the date(s) on which they are
                   made or provided and do not omit any fact necessary in
                   order to make such statements and information not false or
                   misleading in any material respect as of such date(s).

              It is understood and agreed that such statements and information
              in the aggregate are, and in certain instances individually may
              be, material to the Company's decision to offer, provide or so
              continue coverage of the related Loan; the Company issues the
              related Commitment and Certificate or continues coverage in
              reliance on the accuracy and completeness of such statements and
              information and without any obligation to independently verify
              the statements and information submitted to it; and the
              Company's reliance on the representations in Section 2.2(a) and
              (b) above survive the issuance of a Commitment and Certificate
              or such continuation of coverage.

              Without otherwise limiting the scope of this Section 2.2, a
              breach of Section 4.8 relating to down payment will be deemed a
              material misrepresentation for purposes of this Section 2.2. The
              foregoing representations shall be effective whether or not they
              are made by the Insured or other Person with the intent to
              deceive or mislead, or with the knowledge that they are not true
              and correct.

      2.3     Company's Remedies for Misrepresentation -- Subject to Section
              2.4, if any of the Insured's representations as described in
              Section 2.2 are materially false or misleading with respect to a
              Loan, the Company will have at its option, the right to defend
              against a Claim, or to the extent permitted by applicable law,
              to cancel or rescind coverage under any Certificate
              retroactively to commencement of coverage (or if the
              misrepresentation occurs with respect to continuation of
              coverage upon assumption of a Loan, to so defend, cancel or
              rescind retroactively to the date of such continuation). In the
              case of such cancellation or rescission, the Company shall
              return at that time all paid premiums retroactively to such
              applicable date.

      2.4     Incontestability for Certain Misrepresentations --
              Notwithstanding Sections 2.2 or 2.3, no Claim for Loss will be
              denied or adjusted, nor will the Certificate's coverage be
              rescinded or canceled, by reason of any misrepresentations
              (whether by statements made or omitted) contained in an
              Application, provided that all of the following requirements,
              conditions and circumstances, to the extent not waived in
              writing at the option of the Company, are satisfied:

              a.   The misrepresentation must not have been knowingly made,
                   or knowingly participated in, by:

                   1.    The Insured or any other Person which originated the
                         Loan; or

                   2.    Any other of the following Persons:

                         i)   correspondent lender, mortgage loan broker or
                              other intermediary underwriting or processing
                              the Loan on behalf of the Insured or any other
                              Person which originated the Loan; or

                         ii)  escrow or closing agents, or any other agent of,
                              or broker for, the Insured or any other Person
                              which originated the Loan acting with respect to
                              the Loan or the related Property transaction.

              b.   The Borrower must have made twelve (12) consecutive full
                   installment payments of principal, interest and impound or
                   escrow amounts in the amounts as called for by the Loan,
                   and all of those payments must have been made from the
                   Borrower's own funds.

                   A payment will be considered to be "consecutive" only if it
                   is made prior to the date the next scheduled installment
                   becomes due. The "Borrower's own funds" will include any
                   funds used by the Borrower for the purpose of making
                   installment payments, but will not include funds provided
                   directly or indirectly by any Person (other than the
                   Borrower) who is or was a party to the Loan or to the
                   related Property transaction, unless expressly set forth in
                   the Application.

              c.   This Section 2.4 will not apply to a Certificate if within
                   twelve (12) months before or after a material
                   misrepresentation by a Borrower or other Person (other than
                   those Persons identified in Section 2.4(a)), there are one
                   or more material misrepresentations in an Application (i)
                   with respect to three (3) or more other mortgage loans
                   insured at any time by the Company for the Insured or any
                   other lender and (ii) which result from the direct or
                   indirect acts or omissions of the same Borrower or same
                   other Person (including any other Person acting directly or
                   indirectly in concert).

              d.   This Section 2.4 shall not be construed to limit the
                   applicability of Section 4.4(b) to a misrepresentation
                   which is subject to this Section 2.4.

              e.   The Company's payment of a Claim will not limit any rights
                   which the Company has against the Borrower or any other
                   Person (other than the Insured) for any misrepresentation.

      2.5     Initial Premium and Term of Coverage

              a.   Within fifteen (15) days from the Certificate Effective
                   Date, or such other date as the Company and the Insured
                   may agree to in writing, the Insured must forward to the
                   Company the appropriate initial premium. Payment of the
                   initial premium shall be a condition precedent to coverage
                   being extended to the Loan. Subject to cancellation by the
                   Insured or the Company as provided in this Policy,
                   coverage shall remain in full force and effect for the
                   period covered by the initial premium. Tender of the
                   initial premium will constitute a representation for
                   purposes of Section 2.2 by the Insured that any special
                   conditions included by the Company in the related
                   Commitment have been satisfied and that no payment which
                   is then due under the Loan is more than thirty (30) days
                   past due.

              b.   The Company will not rescind or cancel coverage, or deny or
                   adjust a Claim for Loss, with respect to a Loan on the
                   basis of a failure to satisfy a special condition (other
                   than a special condition relating to completion of
                   construction, as described in Section 4.3 or to
                   rehabilitation or repairs) if the Borrower has made
                   twenty-four (24) consecutive full installment payments from
                   the Borrower's own funds. The terms "installment payments,"
                   "consecutive," and "Borrower's own funds" shall have the
                   meanings provided in Section 2.4(b).

      2.6     Renewal of Certificate and Termination for Non-Payment of Renewal
              Premium; Reinstatement of Terminated Coverage

              a.   The Company must give the Insured prior notice of the due
                   date for payment of the applicable renewal premium payable
                   for continued coverage of each Certificate. The entire
                   renewal premium must be paid within a forty-five (45) day
                   grace period (or such longer grace period generally allowed
                   by the Company) after the due date for payment. Upon
                   payment of the entire renewal premium within such grace
                   period, the Certificate will be deemed renewed for the
                   applicable renewal period and a Default occurring within
                   said grace period which is not cured, and which results in
                   a Claim being filed, will be covered.

                   If a Default occurs prior to the date through which the
                   applicable premium has been paid, and if such Default is
                   not cured and results in a Claim being filed, such Default
                   shall remain covered and no further premium shall be due in
                   order to maintain coverage of such Default.

                   With respect to a Loan with renewal premiums due on an
                   annual basis, if the annual renewal premium is not paid
                   within such grace period (but subject to the Owner's right
                   to cure non-payment as provided in (b) of this Section
                   2.6), the coverage of the Certificate and the Company's
                   liability will terminate effective as of 12:01 a.m. on the
                   first day following the date through which the applicable
                   premium has been paid and as a result, any Default
                   occurring after the date through which the applicable
                   premium has been paid will not be covered.

                   With respect to a Loan with renewal premiums due on a
                   monthly basis, if the monthly renewal premium is not paid
                   within such grace period (but subject to the Owner's right
                   to cure non-payment as provided in (b) of this Section
                   2.6), the coverage of the Certificate and the Company's
                   liability will terminate as of 12:01 a.m. on the first day
                   following the date through which the applicable monthly
                   premium has been paid, except that if a Default on the Loan
                   occurs between the last date through which the applicable
                   monthly renewal premium has been paid and the end of such
                   grace period, the Insured shall not be required to pay
                   renewal premiums, and coverage of such Default will
                   continue, while such Default exists. If such Default is
                   cured, all monthly renewal premiums not paid during the
                   period of Default shall be payable (unless previously paid
                   by the Insured) within forty-five (45) days or such longer
                   period generally allowed by the Company after notice from
                   the Company in order to continue coverage. If such Default
                   is not cured and results in a Claim, the unpaid monthly
                   renewal premiums through the renewal month in which such
                   Default occurred shall be paid as provided in Section 6.3
                   by deduction from the Loss.

              b.   If there occurs a transfer of servicing rights for a group
                   of Loans to a new Servicer, a seizure of servicing rights
                   by the Owner of such Loans, or a Servicer's surrender to
                   the Owner of such servicing rights and if:

                   1.    the Company terminates coverage on one or more of
                         such Loans for nonpayment of the renewal premium; and
                         the grace period for payment of the renewal premium
                         provided for in Section 2.6 (a) expired after such
                         transfer, seizure or surrender;

                   2.    either the Owner of such Loans on which coverage was
                         terminated, or the new Servicer for such Loans,
                         certifies in writing to the Company within sixty (60)
                         days after expiration of such grace period, that all
                         of such Loans were serviced for the Owner at the time
                         of nonpayment of renewal premium; and that in good
                         faith it believes that the failure to pay the renewal
                         premium on all such Loans was an error or omission
                         caused by such transfer, seizure or surrender of
                         servicing; and

                   3.    either the Owner or the new Servicer of such Loans
                         pays the entire amount of renewal premiums due and
                         unpaid on all such Loans within such sixty day
                         period; then

                   upon satisfaction of all of the foregoing conditions, the
                   Company shall reinstate coverage on such Loans
                   retroactively to the effective date of termination of
                   coverage, under all of the terms and conditions in effect
                   at termination and as if there had been no lapse in
                   coverage.

      2.7     Special Procedures for Certification of Coverage; Payment of
              Initial and Renewal Premiums

              a.   The Company may permit coverage of a Loan to be certified
                   and become effective without the Insured's return of an
                   executed Commitment or Certificate, but coverage will only
                   become effective if within fifteen (15) days after the
                   Certificate Effective Date (or such longer period as the
                   Company may allow) the Insured provides the Company with
                   the Certificate Effective Date and other information
                   required by the Company, and pays the required premium. If
                   signature and return of an executed Commitment or
                   Certificate is not required, the Insured will nevertheless
                   be automatically deemed to have made all certifications,
                   representations and statements attributable to it in the
                   form of the Commitment or Certificate, as though, and to
                   the same extent as if, the Insured had executed and
                   returned the Commitment or Certificate.

               b.  The Insured acknowledges that the Company deposits initial
                   and renewal premium checks immediately upon receipt and
                   agrees that the receipt and deposit of a premium check by
                   the Company after the time specified in this Policy for
                   receipt, does not constitute a waiver of the requirements
                   of this Policy for timely receipt or an acceptance of
                   premium by the Company. The Company will have the right to
                   return such late premium payment, but only within sixty
                   (60) days after receipt, in which case coverage will be
                   cancelled retroactively to the Certificate Effective Date
                   for a late initial premium, or to the last day of the
                   period covered by the previous premium payment for a late
                   renewal premium. Receipt, deposit and retention of a
                   premium check will not constitute a waiver of any defenses
                   with respect to any other matters which the Company may
                   have under this Policy.

      2.8     Cancellation by the Insured of a Certificate -- The Insured may
              obtain cancellation of a Certificate by returning the
              Certificate to the Company or making a written request to the
              Company for cancellation. Upon receipt, the Company will refund,
              where applicable, a portion of the premium paid in accordance
              with the appropriate cancellation schedule which is either
              attached to this Policy or which will be provided by the Company
              to the Insured upon request. However, no refund on a Certificate
              will be paid if the Loan is in Default on the date the Company
              receives the request. Cancellation of a Certificate will not
              cancel this Policy.

      2.9     Cancellation of Policy -- Either the Insured or the Company may
              cancel their respective right or obligation to receive or issue
              new Commitments or Certificates under this Policy by providing
              thirty (30) days' written notice of cancellation of this Policy.
              However, Commitments and Certificates issued prior to such
              cancellation of this Policy will continue in force so long as
              all premiums are paid and all other terms and conditions of this
              Policy for coverage are complied with by the Insured.

      2.10    Relationship Among the Company, the Owner of a Loan, and the
              Servicer of a Loan -- The Company will be entitled to assume
              that the Insured identified on this Policy and under a
              Certificate is the Owner of the Loan. If the Company receives
              written notice acceptable to it that there is an Owner of the
              Loan who is not the Insured, the Company shall identify that
              Owner in its internal records and for purposes of this Policy.
              The Company shall be required to identify only one Owner for a
              Loan at any one time.

              The Company will provide the Owner of a Loan so identified in
              its records with an opportunity to cure non-payment of renewal
              premium, as provided under Section 2.6; will notify such Owner
              of the Loan of a non-approved Servicer and allow replacement
              with a new Servicer, as provided under Section 4.5; will allow
              the Owner (or its designee, if any) to replace a Servicer and
              allow the replacement Servicer to become the Insured under
              Section 1.13; and will allow the Owner to become the Insured
              under Section 1.13 if the Owner services the Loan itself. Any
              Person becoming an Insured under this Policy shall be subject to
              all of the terms and conditions of this Policy to the same
              extent as any previous Insured hereunder and without regard to
              the extent of the knowledge or responsibility of such Person,
              relating to matters occurring before such Person became an
              Insured.

      2.11    Refund of Premium for Denial of Claim in Full -- If, because of
              a provision in Sections 2, 3 or 4 (other than Sections 4.3, 4.6,
              or 4.7), no Loss is payable to the Insured, the Company shall
              return to the Insured all paid premiums retroactively and pro
              rata to the date when the event or circumstance occurred which
              resulted in no Loss being payable.

3    Changes in Various Loan Terms, Servicing and Owner; Co-ordination and
     Duplication of Insurance Benefits

      3.1     Loan Modifications -- Unless advance written approval is
              provided by, or obtained from, the Company, the Insured may not
              make any change in the terms of a Loan, including the borrowed
              amount, interest rate, term or amortization schedule of the
              Loan, except as permitted by terms of the Loan; nor make any
              change in the Property or other collateral securing the Loan;
              nor release the Borrower from liability on a Loan.

      3.2     Open End Provisions -- The Insured may increase the principal
              balance of a Loan, provided that the written approval of the
              Company has been obtained. The Insured will pay the Company the
              additional premium due at the then prevailing premium rate.

      3.3     Assumptions -- If a Loan is assumed with the Insured's approval,
              the Company's liability for coverage under its Certificate will
              terminate as of the date of such assumption, unless the Company
              approves the assumption in writing. The Company will not
              unreasonably withhold approval of an assumption. It is
              understood that coverage will continue, and that the restriction
              of this Section 3.3 will not apply, if under the Loan or
              applicable law the Insured cannot exercise a "due-on-sale"
              clause or is obligated to consent to such assumption under the
              Loan or applicable law.

      3.4     Change of Servicing -- If the servicing rights for a Loan are
              sold, assigned or transferred by the Insured or the Owner,
              coverage of the Loan hereunder will continue provided that
              written notice of the new Servicer is given to the Company and
              the new Servicer is approved in writing by the Company. The
              Company shall be automatically deemed to have approved as a
              Servicer any person to whom the Company has issued a master
              policy, which has not been cancelled, providing for residential
              mortgage guaranty insurance.

      3.5     Change of Owner -- If a Loan or a participation in a Loan is
              sold, assigned or transferred by its Owner, coverage of the Loan
              will continue, subject to all of the terms and conditions
              contained in this Policy. The new Owner of the Loan will be
              identified in the Company's records from the date that the
              Company receives written notice thereof. In the case of the sale
              of a participation in a Loan, the Company shall be notified of
              only one new Owner. If there is new ownership, the Loan must
              continue to be serviced by a Person approved by the Company as a
              Servicer.

      3.6     Co-ordination and Duplication of Insurance Benefits -- The
              coverage under this Policy shall be excess over any other
              insurance which may apply to the Property or to the Loan, except
              for mortgage guaranty pool insurance or supplemental or second
              tier mortgage insurance.

4     Exclusions From Coverage

      The Company will not be liable for, and this Policy will not apply to,
      extend to or cover the following:

      4.1     Balloon Payment -- Any Claim arising out of or in connection
              with the failure of the Borrower to make any payment of
              principal and/or interest due under a Loan, (a) as a result of
              the Insured exercising its right to call the Loan (other than
              when the Loan is in Default) or because the term of the Loan is
              shorter than the amortization period, and (b) which is for an
              amount more than twice the regular periodic payments of
              principal and interest that are set forth in the Loan (commonly
              referred to as a "balloon payment"). This exclusion will not
              apply if the Insured, the Owner of the Loan, or other Person
              acting on either's behalf offers the Borrower, in writing, a
              renewal or extension of the Loan or a new loan which (i)
              constitutes a first lien, (ii) is at rates and terms generally
              prevailing in the marketplace (but otherwise subject to Section
              3.1), (iii) is in an amount not less than the then outstanding
              principal balance, (iv) has no decrease in the amortization
              period, and (v) is offered regardless of whether the Borrower is
              then qualified under the Insured's or Owner's underwriting
              standards. This exclusion also will not apply if the Borrower is
              notified of the availability of such renewal or extension of the
              Loan or new loan and does not accept the renewal, extension or
              new loan.

      4.2     Effective Date -- Any Claim resulting from a Default existing at
              the Certificate Effective Date or occurring after lapse or
              cancellation of a Certificate.

      4.3     Incomplete Construction -- Any Claim when, as of the date of
              such Claim, construction of a Property is not completed in
              accordance with the construction plans and specifications upon
              which the appraisal of the Property at origination of the Loan
              was based.

      4.4     Fraud, Misrepresentation and Negligence -- (a) Any Claim not
              otherwise within the scope of Section 2.3 where there was fraud
              or misrepresentation by the Insured with respect to the Loan,
              and the fraud or misrepresentation (1) materially contributed to
              the Default resulting in such Claim; or (2) increased the Loss,
              except that if the Company can reasonably determine the amount
              of such increase, such Claim will not be excluded, but the Loss
              will be reduced to the extent of such amount.

              (b) Any Claim where there was negligence by the Insured with
              respect to the Loan, which (1) was material to either the
              acceptance of the risk or the hazard assumed by the Company; (2)
              materially contributed to the Default resulting in such Claim;
              or (3) increased the Loss, except that if the Company can
              reasonably determine the amount of such increase, such Claim
              will not be excluded, but the Loss will be reduced to the extent
              of such amount.

      4.5     Non-Approved Servicer -- Any Claim occurring when the Servicer,
              at time of Default or thereafter, is not approved in writing or
              in a list published by the Company; provided that this exclusion
              shall only apply if the Company notifies the Owner of the Loan
              in writing if a Servicer is no longer approved and if within
              ninety (90) days thereafter the Owner does not complete a
              transfer of servicing to a new Servicer approved by the Company.

      4.6     Physical Damage (Other than Relating to Pre-Existing
              Environmental Conditions) -- Any Claim where, at any time after
              the Certificate Effective Date, Physical Damage to a Property
              (of a type other than as described in Section 4.7 and other than
              reasonable wear and tear), occurs or manifests itself subject to
              the following provisions:

              a.   This exclusion will not apply if the Company in good faith
                   determines that the aggregate cost of restoring all such
                   Physical Damage is less than fifteen hundred dollars
                   ($1,500), or such higher amount as the Company may provide
                   from time to time.

              b.   This exclusion will apply only if such Physical Damage
                   occurred or manifested itself (1) prior to expiration of
                   the Settlement Period and the Company elects to acquire the
                   related Property in settlement of a Claim; or (2) prior to
                   the Default and was the most important cause of the Default
                   and the Property was either uninsured for loss arising from
                   such Physical Damage or was insured for an amount which,
                   disregarding normal and customary deductibles not to exceed
                   fifteen hundred dollars ($1,500) or such higher amount as
                   the Company may provide from time to time, was insufficient
                   to restore the Property as provided in paragraph (c) below.

              c.   The exclusion resulting from paragraph (b) will not apply
                   if the Property is restored in a timely and diligent manner
                   to its condition (except reasonable wear and tear) as of
                   the Certificate Effective Date. In lieu of requiring
                   restoration of the Property, the Company may, at its
                   option, reduce the Claim Amount by an amount equal to the
                   cost of such restoration.

              d.   For purposes of this Section 4.6, the Property subject to
                   restoration will consist only of the land, improvements or
                   personal property deemed part of the real property under
                   applicable law; and chattel items affixed to the real
                   property and identified in the appraisal of the Property at
                   the time the Loan was made, whether or not they are deemed
                   part of the real property.

              e.   Cost estimates relied upon by the Company in connection
                   with this Section 4.6 shall be provided in writing by an
                   independent party selected by the Company. The Company will
                   furnish the Insured with any such written cost estimates,
                   if requested by the Insured.

      4.7     Pre-Existing Environmental Conditions -- Any Claim where there
              is an Environmental Condition which existed on the Property
              (whether or not known by the Person submitting an Application
              for coverage of the Loan) as of the Certificate Effective Date,
              subject to the following provisions:

              a.   This exclusion will not apply if the existence of such
                   Environmental Condition, or the suspected existence of such
                   Environmental Condition, was specifically disclosed to the
                   Company in the Application relating to the Property.

              b.   This exclusion will apply only if such Environmental
                   Condition (1) was a principal cause of the Default, and (2)
                   has made the principal Residential structure on the
                   Property uninhabitable. A structure will be considered
                   "uninhabitable" if generally recognized standards for
                   residential occupancy are violated or if, in the absence of
                   such standards, a fully informed and reasonable person
                   would conclude that such structure was not safe to live in
                   without fear of injury to health or safety.

              c.   This exclusion will not apply if the Environmental
                   Condition is removed or remedied in a timely and diligent
                   manner in accordance with applicable governmental standards
                   for safe residential occupancy.

      4.8     Down Payment -- Any Claim involving a Loan which is for the
              purchase of the Property, and for which the Borrower did not
              make a down payment as described in the Application.

      4.9     First Lien Status -- Any Claim, if the mortgage, deed of trust
              or other similar instrument executed by the Borrower and insured
              hereunder did not provide the Insured at origination with a
              first lien on the Property.

      4.10    Breach of the Insured's Obligations or Failure to Comply with
              Terms -- Any Claim involving or arising out of any breach by the
              Insured of its obligations under, or its failure to comply with
              the terms of, this Policy or of its obligations as imposed by
              operation of law, if the breach or failure:

              a.   Materially contributed to the Default resulting in such
                   Claim; or

              b.   Except for a breach described in Section 2.3, increased the
                   Loss; provided that if the Company can reasonably determine
                   the amount of such increase, such Claim will not be
                   excluded, but the Loss will be reduced to the extent of
                   such amount.

5     Conditions Precedent to Payment of Claim

      It is a condition precedent to the Company's obligation to pay a Loss
      that the Insured comply with all of the following requirements:

      5.1     Notice of Default -- The Insured must give the Company written
              notice:

              a.   Within forty-five (45) days of the Default, if it occurs
                   when the first payment is due under the Loan; or

              b.   Within ten (10) days of either

                   1.   The date when the Borrower becomes four (4) months in
                        Default on the Loan; or

                   2.   The date when any Appropriate Proceedings which
                        affect the Loan or the Property or the Insured's or
                        Borrower's interest therein have been started;

                   whichever occurs first.

      5.2     Monthly Reports -- Following a notice of Default on the Loan,
              the Insured must give the Company monthly reports on forms or in
              a format acceptable to the Company on the status of the Loan and
              on the servicing efforts undertaken to remedy the Default. These
              monthly reports may be furnished less frequently if allowed in
              writing by the Company and must continue until the Borrower is
              no longer in Default, the Appropriate Proceedings terminate, or
              until the Insured has acquired the Property.

      5.3     Company's Option to Accelerate Filing of a Claim -- If the
              Company so directs, at any time after receiving the Insured's
              notice of Default, the Insured must file a Claim within twenty
              (20) days after notice from the Company. The Company will then
              make a payment of Loss in accordance with the percentage
              guaranty option in Section 6.3(b). Thereafter, following the
              acquisition of Borrower's Title by the Insured, the Insured will
              be entitled to file a supplemental Claim at the time prescribed
              in Section 6.1 in an amount equal to the sum of its advances,
              less the deductions, all as specified in Section 6.2, to the
              extent not included in the payment of the initial Claim. Such
              supplemental Claim must be paid by the Company in accordance
              with Section 6.3(b). No interest shall be includable in the
              Claim Amount under this Section 5.3 after the date that the
              accelerated claim is filed. If a Loan for which the Company has
              paid a Claim is subsequently brought current by the Borrower,
              the Insured shall refund to the Company the Loss paid by the
              Company with respect to that Loan. If the Company exercises its
              option under this Section 5.3, the Company shall not have the
              right to direct or participate in a deficiency recovery under
              Section 7.2.

      5.4     Voluntary Conveyance -- The Insured may only accept a conveyance
              of the Property from the Borrower in lieu of foreclosure or
              other proceeding if the prior written approval of the Company
              has been obtained. Such approval shall not be considered as an
              acknowledgement of liability by the Company with respect to such
              Loan.

      5.5     Appropriate Proceedings -- The Insured must begin Appropriate
              Proceedings no later than when the Loan becomes six (6) months
              in Default unless the Company provides written instructions that
              some other action be taken. Such instructions may be general or
              applicable only to specific Loans. The Company reserves the
              right to direct the Insured to institute Appropriate Proceedings
              at any time after Default. When either defending against or
              bringing Appropriate Proceedings, the Insured must report their
              status to the Company as reasonably and expeditiously as
              possible.

              In conducting Appropriate Proceedings, the Insured must:

              a.   Diligently pursue the Appropriate Proceedings once they
                   have begun;

              b.   Apply for the appointment of a receiver and assignment of
                   rents, if permitted by law and requested by the Company;

              c.   Furnish the Company with copies of all notices and
                   pleadings filed or required in the Appropriate
                   Proceedings, except as the Company may waive such
                   requirement in writing;

              d.   Act and bid at the foreclosure sale in accordance with
                   Section 5.11 so that its ability to preserve, transfer and
                   assign to the Company its rights against the Borrower are
                   not impaired; and so that the rights of the Company under
                   this Policy against the Borrower are fully protected. Such
                   rights include any rights to obtain a deficiency judgment,
                   subject to the Company's compliance with Sections 7.2 and
                   7.3 relating to establishing a deficiency; and

              e.   When requested by the Company, furnish the Company with a
                   written statement indicating the estimated potential Claim
                   Amount (as computed under Section 6.2) at least fifteen
                   (15) days before the foreclosure sale.

      5.6     Mitigation of Damages -- The Insured must actively cooperate
              with and assist the Company to prevent and mitigate the Loss,
              including good faith efforts by the Insured to obtain a cure of
              the Default, collect amounts due under the Loan, inspect and
              appraise the Property and effectuate the early disposition of
              the Property. The Company must administer this Policy in good
              faith.

      5.7     Advances -- The Insured must advance:

              a.   Normal and customary hazard insurance premiums and real
                   estate property taxes, in each case as due and payable;

              b.   Reasonable and necessary Property protection and
                   preservation expenses approved by the Company at the time
                   the Company reviews the Claim, which shall not include
                   expenditures to remove an exclusion from coverage under
                   Section 4; and

              c.   Reasonable costs to complete Appropriate Proceedings and
                   eviction and moving of occupants, including related court
                   expenses and attorney's fees.

      5.8     Claim Information and Other Requirements -- The Insured must
              provide the Company with:

              a.   All information reasonably requested by the Company;

              b.   A completed form furnished by or acceptable to the Company
                   for payment of a Claim;

              c.   If the Property is not being acquired by the Company: a
                   copy of an executed trustee's or sheriff's deed (which may
                   be unrecorded) conveying Borrower's Title to the Property
                   to the Insured (or satisfactory evidence that the
                   foreclosure sale has been completed if the Borrower's right
                   of redemption has not expired); or a deed from the Borrower
                   (which may be unrecorded) if a voluntary conveyance has
                   been approved by the Company, conveying to the Insured the
                   title that was required by the Company in the approval of
                   the conveyance.

                   In the event the most important cause of Default was a
                   circumstance or event which would prevent the Insured from
                   obtaining Good and Merchantable Title, the Insured shall
                   instead provide the Company with evidence described in
                   Section 5.8(d)(2) that it has acquired Good and
                   Merchantable Title to the Property.

              d.   If the Property is being acquired by the Company:

                   1.   a recordable deed in normal and customary form
                        containing the customary warranties and covenants
                        conveying to the Company or its designee Good and
                        Merchantable Title to the Property;

                   2.   a title insurance policy acceptable to the Company or
                        an attorney's opinion of title acceptable to the
                        Company, confirming that the Insured has and can
                        convey to the Company Good and Merchantable Title to
                        the Property; and

                   3.   Possession of the Property, but only if the Company
                        has required such Possession in writing.

              e.   Access to the Property, if requested by the Company under
                   Section 6.4 (b).

      5.9     Acquisition of Borrower's Title Not Required -- The Insured will
              not be required to acquire Borrower's Title to a Property if (a)
              the Company approves a sale of the Property prior to a
              foreclosure sale and such sale is closed; (b) the Company
              requires an early Claim filing pursuant to Section 5.3, except
              that such acquisition will be required as a condition to the
              Insured's filing of a supplemental Claim; or (c) the Property is
              acquired by someone other than the Insured at a foreclosure
              sale, as provided in Section 5.11, or thereafter pursuant to
              exercise of rights of redemption.

      5.10    Sale of a Property by the Insured Before End of Settlement Period

              a.   The Insured must submit to the Company any offer to
                   purchase a Property which it receives after the Company has
                   notified the Insured that it will acquire the Property and
                   before the end of the Settlement Period. The Company must
                   then promptly notify the Insured that it will either (1)
                   not approve of such offer, in which case the Company's
                   notice to acquire the Property will remain in effect, or
                   (2) approve such offer, in which case the Company's notice
                   of acquisition will remain in effect, if the approved offer
                   does not close as scheduled. The Insured shall promptly
                   notify the Company if the approved offer does not close as
                   scheduled.

              b.   If the Company has not notified the Insured that it will
                   acquire the Property, and if the Company's right to
                   acquire the Property has not expired pursuant to Section
                   6.5 or has not been waived, the Insured must submit to the
                   Company for approval any offer to purchase the Property
                   which would be acceptable to the Insured. The Company
                   shall then promptly either approve or not approve such
                   offer. If the approved offer expires or is terminated, the
                   Company shall be entitled to pay the Loss payable by (1)
                   paying the percentage guaranty option as calculated under
                   Section 6.3(b), or (2) paying the property acquisition
                   settlement option as calculated under Section 6.3(a), and
                   acquiring the Property; but if the Company's right to
                   acquire the Property has expired pursuant to Section 6.5,
                   or been waived, then such acquisition shall be under the
                   same terms and conditions as the expired or terminated
                   offer, except for terms and conditions relating to the
                   sale price and method of payment of the sale price, which
                   shall instead be governed by Section 6.3.

              c.   The following provisions shall apply to offers submitted
                   to the Company under this Section 5.10:

                    1.  At the time it presents an offer, the Insured must
                        also provide the Company with a good faith estimate
                        of gross proceeds and expenses in sufficient detail
                        for the Company to calculate the estimated net
                        proceeds described below. The Company may not require
                        any changes to the offer or direct the marketing of
                        the Property or expenditures by the Insured for
                        restoration of the Property as a condition to its
                        approval.

                   2.   If the Company approves the offer submitted by the
                        Insured, it must also advise the Insured of the
                        estimated net proceeds which it has calculated. The
                        estimated net proceeds calculated by the Company will
                        be the estimated gross sales proceeds to be received
                        by the Insured less all reasonable estimated expenses
                        submitted by the Insured and approved by the Company
                        in its approval of the offer which have been or are
                        expected to be paid by the Insured in obtaining and
                        closing the sale of the Property. If the estimated
                        net proceeds as calculated by the Company is
                        acceptable to the Insured, the Loss payable shall be
                        computed as determined below. If such calculation is
                        not acceptable to the Insured, the offer shall be
                        deemed to have not been approved by the Company.

                   3.   If the Company approves the offer, the Loss payable
                        by the Company under this Section 5.10 will be the
                        lesser of (i) the actual net amount as calculated
                        below, or (ii) the percentage guaranty option under
                        Section 6.3(b) without regard to a sale of the
                        Property. The actual net amount will be the Claim
                        Amount calculated under Section 6.2, except that (a)
                        delinquent interest will be computed through the
                        closing date for sale of the Property and (b) the
                        Claim Amount shall be reduced by the actual net
                        proceeds realized by the Insured from the sale of the
                        Property. The actual net proceeds will be determined
                        in the same manner as the estimated net proceeds, but
                        on the basis of the actual sales proceeds. For
                        purposes of computing a Loss, such actual net
                        proceeds shall not be less than the estimated net
                        proceeds calculated by the Company under this
                        subparagraph (c), or as otherwise approved by the
                        Company.

                   4.   The Company shall not unreasonably withhold its
                        approval of expenses submitted to it after its
                        approval of an offer. Expenses paid to Persons
                        employed or controlled by the Insured or the Owner of
                        the Loan or their internal costs will not be allowed
                        in calculation of either the estimated or actual net
                        proceeds.

                   5.   If requested by the Company, the Insured shall advise
                        the Company of the name of the real estate broker or
                        other Person marketing the Property and authorize
                        such broker or other Person to release marketing
                        information about the Property to the Company, if
                        requested by the Company.

      5.11    Foreclosure Bidding Instructions Given by the Company -- The
              Insured will be entitled to bid at the foreclosure sale held as
              part of the Appropriate Proceedings any amount which it
              determines necessary to obtain Borrower's Title to the Property,
              unless otherwise directed by the Company. The Company will be
              entitled to direct the Insured to bid an amount to be determined
              by the Insured within a minimum and maximum range, as follows:

              a.   The minimum amount shall not be less than the fair market
                   value of the Property, but if there has been Physical
                   Damage to the Property which affects its fair market value
                   (as determined before such Physical Damage) by more than
                   ten per cent (10%), the fair market value of the Property
                   shall be its fair market value after restoration of the
                   Property.

              b.   The maximum amount shall not exceed the greater of (1) the
                   fair market value of the Property as determined under
                   subparagraph (a) above, or (2) the estimated Claim Amount
                   less the amount which the Company would pay as the
                   percentage guaranty option under Section 6.3(b).

              c.   For purposes of this Section 5.11, fair market value shall
                   be determined as of a date acceptable to the Company by an
                   opinion of an independent real estate broker, or by an
                   independent appraiser, in either case selected by or
                   acceptable to the Company.

              The Insured is not required to acquire Borrower's Title if it
              has bid in accordance with this Section 5.11, whether or not
              pursuant to directions from the Company.

      5.12    Effect of Unexpired Redemption Period on Payment of a Claim --
              If the Insured files a Claim prior to expiration of an
              applicable redemption period, the Loss payable shall only be
              computed through the date of filing of the Claim, and if the
              Company elects to acquire the Property, the Insured will remain
              responsible for management and control of the Property until the
              Company's acquisition thereof, which may be after expiration of
              the redemption period, but not later than as required by Section
              6.4.

              If the Company has paid to the Insured a Claim under its
              percentage guaranty option in Section 6.3 (b), and the related
              Property is subsequently redeemed by the Borrower, the Insured
              shall promptly report such redemption to the Company and
              reimburse the Company for the amount of the Company's Claim
              payment, to the extent that the sum of the Company's Claim
              payment and the amount realized by the Insured from the
              redemption exceeds the Claim Amount, as would have been
              calculated through the date of redemption.

      5.13    Collection Assistance -- If the Company so requests, the Insured
              shall permit the Company to cooperatively assist the Insured in
              the collection of moneys due under the Loan, including obtaining
              information from the Borrower, attempting to develop payment
              schedules acceptable to the Insured, conducting Property
              inspections and requesting appraisals of the Property.

6     Loss Payment Procedure

      6.1     Filing of Claim -- The Insured shall file a Claim after, but no
              later than sixty (60) days following, the conveyance to the
              Insured of Borrower's Title to the Property. If the Insured is
              not required to have Borrower's Title to file a Claim for a
              reason described in Section 5.9, then the Claim must be filed
              (a) within sixty (60) days after the Property is conveyed in a
              pre-foreclosure sale, at the foreclosure sale, or by exercise of
              the rights of redemption or (b) at the time specified by Section
              5.3. If the Insured fails to file a Claim within the applicable
              time, the Insured will not be entitled to, and the Company will
              not be obligated for, any payment under this Policy for amounts,
              including additional interest and expenses, which would
              otherwise be claimable, but which accrue or are incurred after
              the sixty (60) day period for filing of a Claim.

              If the Insured fails to file a Perfected Claim within one
              hundred eighty (180) days after the filing of the Claim (or
              within such longer period of time as the Company may allow in
              writing), the Insured will no longer be entitled to payment of a
              Loss and the Company will not be obligated to make any payment
              under this Policy.

      6.2     Calculation of Claim Amount --  Subject to Sections 7.5 and 5.3,
              the Claim Amount will be an amount equal to the sum of:

              a.   The amount of unpaid principal balance due under the Loan
                   as of the date of Default without capitalization of
                   delinquent interest, penalties or advances; and

              b.   The amount of accrued and unpaid interest due on the Loan
                   computed at the contract rate stated in the Loan through
                   the date that the Claim is filed with the Company, but
                   excluding applicable late charges, penalty interest or
                   other changes to the interest rate by reason of Default;
                   and

              c.   The amount of advances incurred by the Insured under
                   Section 5.7 prior to filing of the Claim (except to Persons
                   employed or controlled by the Insured or the Owner of the
                   Loan or their other internal costs) provided that:

                   1.   Attorney's fees advanced for completion of
                        Appropriate Proceedings and obtaining Possession of
                        the Property will not be allowed to the extent they
                        exceed three percent (3%) of the sum of the unpaid
                        principal balance and the accrued and accumulated
                        interest due; and

                   2.   Such advances, other than attorney's fees, must have
                        first become due and payable after the Default, and
                        payment of such advances must be prorated through the
                        date the Claim is filed with the Company;

              less:

              (i)    The amount of all rents and other payments (excluding
                     proceeds of a sale of the Property and the proceeds of
                     fire and extended coverage insurance) collected or
                     received by the Insured, which are derived from or in any
                     way related to the Property;

              (ii)   The amount of cash remaining in any escrow account as of
                     the last payment date;

              (iii)  The amount of cash or other collateral to which the
                     Insured has retained the right of possession as security
                     for the Loan;

              (iv)   The amount paid under applicable fire and extended
                     coverage policies which are in excess of the cost of
                     restoring and repairing the Property, if the Property is
                     damaged, and which has not been paid to the Borrower or
                     applied to the payment of the Loan as required by the
                     terms of the Loan; and

              (v)    Any other amounts claimed by the Insured to the extent
                     they are excluded from the Claim Amount by reason of
                     Section 4.

      6.3     Payment of Loss; Company's Options -- Within the Settlement
              Period, but only if the Insured has satisfied all requirements
              for a payment of Loss and if the Company has received a
              Perfected Claim, the Company shall at its sole option exercise
              its:

              a.   Property acquisition settlement option. Pay to the Insured
                   as the Loss the Claim Amount calculated in accordance with
                   Section 6.2 for the Company's acquisition of the Property;
                   or

              b.   Percentage guaranty option. Allow the Insured to retain
                   all rights in and title to the Property, and pay to the
                   Insured as the Loss the Claim Amount calculated in
                   accordance with Section 6.2 of this Policy multiplied by
                   the percentage of coverage or as otherwise calculated as
                   specified in the Certificate. However, if prior to the
                   Company's payment of the Loss, a third party acquires
                   title to the Property at the foreclosure sale or a
                   Borrower redeems the Property (unless such acquisition or
                   redemption occurs because the Insured failed to bid as
                   provided in Section 5.11), then the Company shall pay the
                   lesser of: (i) the percentage guaranty option amount
                   described above; or (ii) the difference between the Claim
                   Amount and the amount realized by the Insured at the
                   foreclosure sale or redemption; or

              c.   Pre-Claim sale option. Pay to the Insured as the Loss the
                   amount calculated in accordance with Section 5.10, if the
                   terms and conditions of Section 5.10 are met.

              In addition to the sum due pursuant to the option described
              above which the Company selects, the Loss payable by the Company
              will include the other amounts provided for under Sections 6.5
              or 7.2 when such Sections are applicable. The Company will
              deduct from its payment of Loss such amounts as may be permitted
              by this Policy and the aggregate amounts of any payments of Loss
              which it had previously made. In the event of a Loss on a Loan
              with renewal premiums due monthly, which results from a Default
              covered under Section 2.6(a), the Company shall deduct from the
              payment of Loss an amount equal to any unpaid renewal premiums
              for the subject Loan through the end of the monthly renewal
              period in which such Default occurred.

      6.4     Calculation of Settlement  Period -- The Settlement  Period will
              be a sixty (60) day period after the Company's receipt of a
              Claim, calculated as follows:

              a.   No later than the twentieth (20th) day after filing of a
                   Claim, the Company may notify the Insured of additional
                   documents or information which it requires for processing
                   the Claim. The sixty-day period will be suspended until
                   the Company receives such additional documents and
                   information. The Company may request additional documents
                   and information after such twenty-day period, and the
                   Insured must use reasonable efforts to satisfy such
                   request.

              b.   No later than the sixtieth (60th) day after filing of a
                   Claim, the Company may notify the Insured that it will
                   require access to the Property sufficient to inspect,
                   appraise and evaluate the Property. If the Company does
                   not notify the Insured by that date, its right to such
                   access will be deemed waived. If such notice is given, the
                   Insured will use its best efforts to provide access to the
                   Company and, if access is not then available, the sixty
                   day period will be suspended from the date such notice was
                   given until the Company receives notice from the Insured
                   that access is available to it. If access is in fact not
                   available when sought by the Company after such notice
                   from the Insured, the Company will promptly notify the
                   Insured of such unavailability, and the passage of the
                   sixty day period will remain suspended as if the Insured's
                   notice of availability had not been given to the Company.

              c.   If the Company has elected to acquire the Property in
                   settlement of a Claim, the sixty day period also will be
                   suspended if necessary for there to be a period of ten
                   (10) days after the date on which the Insured satisfies
                   all conditions to acquisition, including any required
                   restoration of the Property, for the Insured's delivery of
                   a recordable deed and title policy or opinion evidencing
                   Good and Merchantable Title (not subject to any rights of
                   redemption, unless the Company waives such requirement)
                   and, if applicable, delivery of Possession to the
                   Property.

              d.   If the sixty day period is suspended for more than one
                   reason, the resulting suspended periods will only be
                   cumulative if in fact they occur at different times; to
                   the extent they occur simultaneously, they will not be
                   cumulative.

      6.5     Payment by the Company After the Settlement Period -- If the
              Company has not paid a Loss during the Settlement Period, then
              (a) the Company will include in its payment of Loss, if a Loss
              is ultimately payable, simple interest on the amount payable
              accruing after the Settlement Period to the date of payment of
              Loss at the applicable interest rate or rates which would have
              been payable on the Loan during such period, and (b) the Company
              will no longer be entitled to acquire the Property as an option
              for payment of the Loss.

              The Company must either pay the amount of applicable Loss
              (including any additional applicable interest as computed above)
              or deny the Claim in its entirety within (a) one hundred twenty
              (120) days after expiration of the Settlement Period, or (b) if
              the Settlement Period has not expired, no later than one hundred
              eighty (180) days after filing of the Claim. If at a later date
              it is finally determined by agreement between the Insured and
              the Company (or by completion of legal or other proceedings to
              which the Insured and the Company are parties) that the Company
              was not entitled to deny all or a portion of the Claim, the
              Company will include in any resulting subsequent payment of Loss
              interest as calculated above through the date of such payment on
              the amount of Loss which the Company was not entitled to deny.

      6.6     Discharge of Obligation -- Payment by the Company of the amount
              of Loss required to be paid in accordance with this Policy will
              be a full and final discharge of its obligation with respect to
              such Loss under this Policy.

7     Additional Conditions

      7.1     Proceedings of Eminent Domain -- In the event that part or all
              of a Property is taken by eminent domain, or condemnation or by
              any other proceedings by federal, state or local governmental
              unit or agency, the Insured must require that the Borrower apply
              the maximum permissible amount of any compensation awarded in
              such proceedings to reduce the principal balance of the Loan, in
              accordance with the law of the jurisdiction where the Property
              is located.

      7.2     Pursuit of Deficiencies

               a.   The Insured will be entitled to pursue Appropriate
                    Proceedings, or shall at the direction of the Company
                    pursue Appropriate Proceedings through the end of the
                    Settlement Period, which may result in the Borrower
                    becoming liable for a deficiency after completion of the
                    Insured's acquisition of a Property. Such pursuit may not
                    be directed by the Company unless such deficiency is
                    estimated to exceed $7,500. If the Company proposes to
                    pursue a deficiency judgment, in whole or in part for its
                    account, it will notify the Insured at least thirty (30)
                    days before the foreclosure sale. If the Company does not
                    so notify the Insured, the deficiency judgment, if
                    established by the Insured, will be solely for the account
                    of the Insured, and the Company will not be subrogated to
                    any rights to pursue the deficiency judgment.

             b.     The following provisions will apply if, in completing
                    Appropriate Proceedings there are additional expenses
                    advanced pursuant to Section 5.7 or additional interest
                    accrued on the Loan, due to (1) an additional redemptive
                    period or a delay in acquisition of Borrower's Title,
                    which period or delay is directly related to establishing
                    the deficiency judgment or (2) legal proceedings which
                    are necessary to establish and pursue the deficiency
                    judgment and which would not otherwise be the custom and
                    practice used.

                    i.     If the deficiency judgment is to be established,
                           in whole or in part, for the account of the
                            Company, the Company must pay the Insured at the
                            time of payment of the Claim, regardless of which
                            settlement option the Company has selected, the
                            full amount of:

                            (A)   such additional expenses advanced pursuant to
                                  Section 5.7 by the Insured; and

                            (B)   such additional interest accrued on the
                                  unpaid principal balance of the Loan at the
                                  contract rate stated in the Loan, but
                                  excluding applicable late charges, penalty
                                  interest, or other changes to the interest
                                  rate by reason of Default.

                     ii.    If the deficiency judgment is not to be
                            established, in whole or in part, for the account
                            of the Company, none of the additional interest or
                            expenses of the type described in subparagraph (i)
                            above will be includable in the Claim Amount or
                            payable at any time by the Company.

                     iii.   For purposes of determining the additional
                            expenses described in subparagraph (i) above
                            resulting from pursuing the deficiency judgment,
                            the limitation on attorneys' fees in Section 6.2
                            will not apply.

                     iv.    All of the additional interest, expenses,
                            attorney's fees and court expenses described in
                            subparagraph (i) above will be accrued or advanced
                            only through acquisition of Borrower's Title,
                            including any additional redemptive period.

              c.     The Company and the Insured may agree generally or with
                     respect to a Loan to different terms and conditions than
                     set forth in this Section 7.2. The Company and the
                     Insured also may agree to the joint pursuit or other
                     arrangements for the collection of deficiency judgments
                     on mutually acceptable terms and conditions.

      7.3     Subrogation -- Subject to Section 7.2(a), and only to the extent
              that the Company is entitled under applicable law to pursue such
              deficiency rights, the Company will be subrogated, upon payment
              of the Loss, in the amount thereof and with an equal priority to
              all of the Insured's rights of recovery against a Borrower and
              any other Person relating to the Loan or to the Property. The
              Insured must execute and deliver at the request of the Company
              such instruments and papers and undertake such actions as may be
              necessary to transfer, assign and secure such rights. The
              Insured shall refrain from any action, either before or after
              payment of a Loss, that prejudices such rights.

      7.4     Policy for Exclusive Benefit of the Insured and the Owner -- A
              Commitment and Certificate issued as the result of any
              Application submitted hereunder and the coverage provided under
              this Policy will be for the sole and exclusive benefit of the
              Insured and the Owner of the related Loan, and in no event will
              any Borrower or other Person be deemed a party to, or an
              intended beneficiary of, this Policy or any Commitment or
              Certificate.

      7.5     Effect of Borrower Insolvency or Bankruptcy on Principal Balance
              -- If under applicable insolvency or bankruptcy law, a Loan's
              principal balance secured by a Property is reduced (after all
              appeals of such reduction are final or the time for such appeals
              has lapsed without appeal), the portion of such principal
              balance of the Loan not secured by the Property, and related
              interest, will be includable in the Claim Amount, as provided in
              this Section 7.5.

              If a Default occurs on the Loan, the Insured has acquired
              Borrower's Title or Good and Merchantable Title to the Property
              as required by this Policy, and all other requirements for
              filing of a Claim are complied with, the Insured will be
              entitled to include in the Claim Amount (a) the amount of the
              principal balance of the Loan which was deemed unsecured under
              applicable insolvency or bankruptcy law, less any collections or
              payments on such unsecured principal balance received by the
              Insured, and (b) interest thereon at the rate and as computed in
              Section 6.2, from the date of Default giving rise to the Claim
              (but for no prior period). In no event will any expenses or
              other amounts associated with the amount by which the principal
              balance of the Loan became unsecured be includable in the Claim
              Amount, directly or by an addition to the principal balance
              includable in the Claim Amount.

      7.6     Arbitration of Disputes; Suits and Actions Brought by the Insured

              a.   Unless prohibited by applicable law, all controversies,
                   disputes or other assertions of liability or rights
                   arising out of or relating to this Policy, including the
                   breach, interpretation or construction thereof, shall be
                   settled by arbitration. Notwithstanding the foregoing, the
                   Company or the Insured both retain the right to seek a
                   declaratory judgement from a court of competent
                   jurisdiction on matters of interpretation of the Policy.
                   Such arbitration shall be conducted in accordance with the
                   Title Insurance Arbitration Rules of the American
                   Arbitration Association in effect on the date the demand
                   for arbitration is made, or if such Rules are not then in
                   effect, such other Rules of the American Arbitration
                   Association as the Company may designate as its
                   replacement.

                   The arbitrator(s) shall be neutral person(s) selected from
                   the American Arbitration Association's National Panel of
                   Arbitrators familiar with the mortgage lending or mortgage
                   guaranty insurance business. Any proposed arbitrator may
                   be disqualified during the selection process, at the
                   option of either party, if they are, or during the
                   previous two (2) years have been, an employee, officer or
                   director of any mortgage guaranty insurer, or of any
                   entity engaged in the origination, purchase, sale or
                   servicing of mortgage loans or mortgage-backed securities.

              b.   No suit or action (including arbitration hereunder)
                   brought by the Insured against the Company with respect to
                   the Company's liability for a Claim under this Policy
                   shall be sustained in any court of law or equity or by
                   arbitration unless the Insured has substantially complied
                   with the terms and conditions of this Policy, and unless
                   the suit or action is commenced within three (3) years
                   (five (5) years in Florida or Kansas) after the Insured
                   has acquired Borrower's Title to the Property or sale of
                   the Property approved by the Company is completed,
                   whichever is applicable to a Loan. No such suit or action
                   with respect to a Claim may be brought by the Insured
                   against the Company until sixty (60) days after such
                   acquisition of Borrower's Title or sale, as applicable to
                   a Loan.

              c.   If a dispute arises concerning the Loan which involves
                   either the Property or the Insured, the Company has the
                   right to protect its interest by defending the suit, even
                   if the allegations contained in such suit are groundless,
                   false or fraudulent. The Company is not required to defend
                   any lawsuit involving the Insured, the Property or the
                   Loan.

      7.7     Release of Borrower; Defenses of Borrower -- The Insured's
              execution of a release or waiver of the right to collect any
              portion of the unpaid principal balance of a Loan or other
              amounts due under the Loan will release the Company from its
              obligation under its Certificate to the extent and amount of
              said release. If, under applicable law, the Borrower
              successfully asserts defenses which have the effect of
              releasing, in whole or in part, the Borrower's obligation to
              repay the Loan, or if for any other reason the Borrower is
              released from such obligation, the Company will be released to
              the same extent and amount from its liability under this Policy,
              except as provided by Section 7.5.

      7.8     Amendments; No Waiver; Rights and Remedies; Use of Term
              "Including"

              a.     The Company reserves the right to amend the terms and
                     conditions of this Policy from time to time; provided,
                     however, that any such amendment will be effective only
                     after the Company has given the Insured written notice
                     thereof by endorsement setting forth the amendment. Such
                     amendment will only be applicable to those Certificates
                     where the related Commitment was issued on or after the
                     effective date of the amendment.

              b.     No condition or requirement of this Policy will be deemed
                     waived, modified or otherwise compromised unless that
                     waiver, modification or compromise is stated in a writing
                     properly executed on behalf of the Company. Each of the
                     conditions and requirements of this Policy is severable,
                     and a waiver, modification or compromise of one will not
                     be construed as a waiver, modification or compromise of
                     any other.

              c.     No right or remedy of the Company provided for by this
                     Policy will be exclusive of, or limit, any other rights
                     or remedies set forth in this Policy or otherwise
                     available to the Company at law or equity.

              d.     As used in this Policy, the term "include" or "including"
                     will mean "include or including, without limitation."

      7.9     No Agency -- Neither the Insured, any Servicer or Owner, nor any
              of their employees or agents, will be deemed for any reason to
              be agents of the Company. Neither the Company, nor any of its
              employees or agents, will be deemed for any reason to be agents
              of any Insured, Servicer or Owner.

      7.10    Successors and Assigns -- This Policy will inure to the benefit
              of and shall be binding upon the Company and the Insured and
              their respective successors and permitted assigns.

      7.11    Applicable Law and Conformity to Law -- All matters under this
              Policy will be governed by and construed in accordance with the
              laws of the jurisdiction in which the office of the original
              Insured on a Certificate is located. Any provision of this
              Policy which is in conflict with any provision of the law of
              such jurisdiction is hereby amended to conform to the provisions
              required by that law.

      7.12    Notice -- All claims, premium payments, tenders, reports, other
              data and any other notices required to be submitted to the
              Company by the Insured must be sent to the Company at MGIC
              Plaza, 250 East Kilbourn Avenue, Milwaukee, WI 53202. The
              Company may change this address by giving written notice to the
              Insured. Unless the Insured otherwise notifies the Company in
              writing, all notices to the Insured must be sent to the address
              on the face of this Policy or, if the Insured is not located at
              such address, to the last known address of the Insured.

              All notices under this Policy, whether or not identified in this
              Policy as required to be in writing, will be effective only if
              in writing and only upon receipt thereof. Written notices may
              instead be given in the form of telecopy or, if acceptable to
              the Company (for notices given to the Company) or to the Insured
              (for notices given to the Insured) in the form of computer tape
              or computer-generated or any other electronic message. A
              telecopy or such tape or message shall be effective only when
              received. The Company and the Insured may mutually agree that
              notices will be sent to any additional Person. Except as
              expressly agreed to by the Company and the Insured, no liability
              shall be incurred by the Company for the failure to give a
              notice to a Person other than the Insured.

      7.13    Reports and Examinations -- The Company may request, and the
              Insured must provide, such files, reports or information as the
              Company may deem necessary pertaining to any Loan, and the
              Company will be entitled to inspect the files, books and records
              of the Insured or any of its representatives pertaining to such
              Loan.

      7.14    Electronic Media -- The Company and the Insured may, from time
              to time, deliver or transfer information, documents or other
              data between them by electronic media acceptable to them. In
              addition, the Company and the Insured may maintain information,
              documents or other data on electronic media or other media
              generally accepted for business records, including microfiche.
              Such electronic or other media will be as equally acceptable for
              all purposes between the Insured and the Company as information,
              documents or other data maintained in printed or written form.

The purpose of this Endorsement is to amend terms and conditions of the Policy
to provide for the insurance of Loans under the Master Reporting Program made
available by the Company to certain Insureds to whom this Endorsement is
issued. An Insured will be entitled to submit Loans for insurance under this
Endorsement unless this Endorsement is revoked by the Company. The Company
reserves the right to revoke this Endorsement immediately upon written notice
to the Insured. This Endorsement will apply only to a Loan which is identified
by the Company as being insured under the Master Reporting Program. To the
extent of any inconsistency or conflict between the terms of the Policy and
this Endorsement, this Endorsement will control. The Policy is amended by
adding, deleting, or amending the following terms and conditions, as
indicated:

A.       The following additional definitions are added to Section 1 of the
         Policy:

         1.27     Eligibility Criteria means the requirements
                  established by the Company from time to time applicable to
                  the origination of a Loan (including approved mortgage loan
                  programs, maximum loan-to-value ratios and original
                  principal amounts, coverage limitations and underwriting
                  requirements) and of which the Company notifies the Insured,
                  as the same may be amended from time to time by the Company
                  on prior written notice to the Insured.

         1.28     Transmittal means the information and format
                  designated as such by the Company which requests or directs
                  the Company to issue its Commitment and tender its
                  Certificate with respect to the Loan identified therein,
                  which may be identified by the title "Transmittal" and which
                  includes all data and information and all exhibits and
                  documents furnished in connection therewith to the Company.
                  Whenever the term "Application" is used in this Policy, the
                  term "Transmittal" and its definition will be substituted
                  therefor.

         1.29     Loan File means, with respect to a Loan, copies of all
                  documents (including all data and information in electronic
                  format) created or received in connection with the
                  origination and closing of the Loan, including the
                  Borrower's loan application, purchase contract, appraisal,
                  credit report, verifications of employment, income and
                  deposit, and HUD-1 or other settlement statement.

B.       Sections 2.1 through 2.4 of the Policy are deleted in their entirety
         and replaced with the following:

         2.1      Loan Underwriting and Obtaining Coverage -- This
                  Policy shall automatically extend to each Loan which the
                  Insured makes, provided that it is made in accordance with
                  the terms and provisions of this Policy, including the
                  Eligibility Criteria, and is evidenced by a Certificate
                  issued by the Company. In order to obtain coverage under
                  this Policy for a Loan, the Insured or the Person acting on
                  its behalf must submit a duly completed Transmittal to the
                  Company within thirty (30) days after the Insured makes the
                  Loan (or such longer period as allowed by the Company), and
                  the Company shall then issue a Commitment and Certificate,
                  if all applicable requirements are satisfied.

                  If the Insured or the Person acting on its behalf
                  subsequently denies the mortgage loan application received
                  by it from the applicant, the Insured will be responsible
                  for notifying the applicant in compliance with any
                  applicable state or federal laws or regulations, including
                  the Equal Credit Opportunity Act and any other similar law
                  or regulation.

         2.2      Representations of the Insured , The Insured represents to
                  the Company that:

                  a.       All statements made and information provided to the
                           Company in a Transmittal or in a Commitment or
                           Certificate (including as such is related to
                           continuation of coverage upon assumption of a Loan)
                           are supported by statements and information in the
                           Loan File;

                  b.       All statements made and information
                           provided to the Company in the Transmittal or in
                           any Commitment or Certificate when provided to the
                           Company or in the Loan File when the Loan is closed
                           by the Insured are not false or misleading in any
                           material respect as of such date(s) and do not omit
                           any fact necessary in order to make such statements
                           and information not false or misleading in any
                           material respect as of such date(s); and

                  c.       The Loan complies with the Eligibility Criteria in
                           effect at the time the Transmittal is submitted to
                           the Company.

                  The foregoing representations will apply to all statements
                  and information provided to the Company in the Transmittal,
                  Commitment or Certificate or Loan File, whether made or
                  submitted by the Insured, the Borrower or any other Person,
                  and will be deemed to have been made and provided for and on
                  behalf of the Insured. The foregoing representations shall
                  be effective whether or not they are made by the Insured or
                  other Person with the intent to deceive or mislead, or with
                  the knowledge that they are not true and correct.

                  It is understood and agreed that such statements and
                  information in the Transmittal, Commitment or Certificate,
                  or Loan File in the aggregate are, and in certain instances
                  individually may be, material to the Company's decision to
                  offer, provide or so continue coverage of the related Loan;
                  the Company issues the related Commitment and Certificate or
                  continues coverage in reliance on the accuracy and
                  completeness of such statements and information submitted to
                  it; and the Company's reliance on the representations in
                  this Section 2.2 survive the issuance of a Commitment and
                  Certificate or such continuation of coverage and any later
                  review or audit of the Insured's files by the Company.
                  Without otherwise limiting the scope of this Section 2.2, a
                  breach of Section 4.8 relating to down payment will be
                  deemed a material misrepresentation for purposes of this
                  Section 2.2.

2.3               Company's Remedies for Misrepresentation -- Subject to
                  Section 2.4, if any of the Insured's representations as
                  described in Section 2.2 are materially false or misleading
                  with respect to a Loan, the Company will have at its option,
                  the right to defend against a Claim, or to the extent
                  permitted by applicable law, to cancel or rescind coverage
                  under any Certificate retroactively to commencement of
                  coverage (or if the misrepresentation occurs with respect to
                  continuation of coverage upon assumption of a Loan, to so
                  defend, cancel or rescind retroactively to the date of such
                  continuation). In the case of such cancellation or recision,
                  the Company shall return at that time all paid premiums
                  retroactively to such applicable date.

         2.4      Incontestability for Certain Misrepresentations --
                  Notwithstanding Sections 2.2 and 2.3, no Claim for Loss will
                  be denied or adjusted, nor will such Certificate's coverage
                  be rescinded or canceled, by reason of any
                  misrepresentations (whether by statements made or
                  information provided, or of statements or information
                  omitted) contained in a Transmittal or the related Loan
                  File, provided that all of the following requirements,
                  conditions and circumstances, to the extent not waived in
                  writing at the option of the Company, are satisfied:

                  a.       The misrepresentation must not have been knowingly
                           made, or knowingly participated in, by:

                           1.       The Insured or any other Person which
                                    originated the Loan; or

                           2.       Any other of the following Persons:

                                    i)      correspondent lender,
                                            mortgage loan broker or other
                                            intermediary underwriting or
                                            processing the Loan on behalf of
                                            the Insured or any other Person
                                            which originated the Loan; or

                                   ii)      escrow or closing agents,
                                            or any other agent of, or broker
                                            for, the Insured or any other
                                            Person which originated the Loan
                                            acting with respect to the Loan or
                                            the related Property transaction.

                  b.       This Section 2.4 will not apply to a Certificate if
                           within twelve (12) months before or after a material
                           misrepresentation by a Borrower or other Person
                           (other than those Persons identified in Section
                           2.4(a) above), there are one or more material
                           misrepresentations in a Transmittal or Loan File (i)
                           with respect to three or more other mortgage loans
                           insured at any time by the Company for the Insured
                           or any other lender and (ii) which result from the
                           direct or indirect acts or omissions of the same
                           borrower or same other Person (including any other
                           Person acting directly or indirectly in concert).

                  c.       This Section 2.4 shall not be construed to limit the
                           applicability of Section 4.4(b) to a
                           misrepresentation covered by this Section 2.4.

                  d.       The Company's payment of a Claim will not
                           limit any rights which the Company has against the

- ------------------------------------------------------------------------------------------------------------------


The purpose of this Endorsement is to amend terms and conditions of the Policy
to provide for an aggregate loss limit for the mortgage guaranty insurance
coverage under the Policy. To the extent of any inconsistency or conflict
between the terms of the Policy and this Endorsement, this Endorsement will
control. The terms and conditions of this Endorsement shall apply to the
coverage of all Loans under the Policy.

I.     Aggregate Loss Limit.

A.       The following definitions are added to the Policy:

         1.40     Aggregate Loss means, at any given time, the total of
                  all Losses on Loans which are subject to this Policy,
                  including advance payments of Loss and partial payments of
                  Loss with respect to a Default, paid by the Company, reduced
                  by the net proceeds received by the Company upon disposal of
                  Properties acquired by the Company in settlement of such
                  Losses. For purposes hereof, the term "net proceeds" shall
                  consist of the sale price received by the Company, reduced
                  by any expenses, payments or costs incurred by the Company
                  in the ownership, maintenance and disposition of a Property,
                  including all expenses of the type which would have been
                  includable in a Claim for Loss, brokerage commissions, title
                  insurance expenses, recording fees, and other costs and
                  expenses of closing the sale of the Property; and expenses
                  regarding the physical condition of the Property in order to
                  make it ready for sale.

         1.41     Aggregate Loss Limit means the Total Initial Principal
                  Balance (as shown on this Policy) of Loans which are subject
                  to this Policy, multiplied by the Aggregate Loss Percentage.
                  The Aggregate Loss Limit represents the maximum aggregate
                  amount payable by the Company under this Policy, and when
                  the Aggregate Losses paid by the Company under this Policy
                  are an amount equal to the Aggregate Loss Limit, the
                  liability of the Company to pay any additional Losses
                  ceases, unless and until the Aggregate Losses are reduced
                  below the Aggregate Loss Limit.

         1.42     Aggregate Loss Percentage means that percentage
                  identified on this Policy, as such percentage may be
                  adjusted and in effect from time to time as set forth on
                  such Endorsement.

         1.43     Initial Principal Balance means the unpaid principal balance
                  at the Certificate Effective Date of a Loan which is
                  subject to this Policy.

         1.44     Total Initial Principal Balance means the sum of the Initial
                  Principal Balances of all Loans insured under this
                  Policy.

    B.    Section 1.15 is deleted in its entirety and replaced with the
          following:

         1.15     Loss means the liability of the Company with respect
                  to a Loan for payment of a Perfected Claim which is
                  calculated in accordance with Section 6.3, but subject to
                  the Aggregate Loss Limit. A Loss will be deemed to have
                  occurred when a Default on a Loan occurs, even though the
                  amount of Loss is not then either presently ascertainable or
                  due and payable.

    C.   The introduction to Section 6.2 is deleted in its entirety and
         replaced with the following:

         6.2      Calculation  of Claim  Amount --- Subject to Sections  7.5
                  and 5.3,  and to the  Aggregate  Loss Limit,  the Claim
                  Amount will be an amount equal to the sum of:

    D.   The following is added as the new last sentence of Section 6.3 of the
         Policy:

                  When the Aggregate Loss paid by the Company under this
                  Policy is an amount equal to the Aggregate Loss Limit, the
                  liability of the Company to pay any additional Claims for
                  Losses ceases until the Aggregate Loss is reduced below the
                  Aggregate Loss Limit, at which time this Section 6.3 will
                  again apply to any previously Perfected Claims.

II.    Construction and Interpretation. All terms capitalized will have
       the meanings set forth in the Policy, except as otherwise defined
       herein. Nothing herein contained will be held to vary, alter, waive or
       extend any of the terms and conditions of the Policy, or any amendments
       thereto, except as expressly set forth above.

The purpose of this Endorsement is to amend certain terms and conditions of
the Policy as provided herein. An Insured will be entitled to submit Loans for
insurance under this Endorsement unless this Endorsement is revoked by the
Company. The Company reserves the right to revoke this Endorsement for future
mortgage loans submitted to it, effective upon written notice to the Insured.
This Endorsement will apply only to a Loan which is approved by the Company
for insurance under it, which approval shall include a Loan underwritten by
the Insured in accordance with the Company's Master Reporting Program
(Delegated Underwriting Program). To the extent of any inconsistency or
conflict between the terms of the Policy and this Endorsement, this
Endorsement will control. The terms and conditions of the Policy shall apply
to a Loan insured under this Endorsement, but with the Policy amended by
adding, deleting, or amending the following terms and conditions, as
indicated:

    A.    Section 1.13 of the Policy is deleted in its entirety and replaced
          with the following:

          1.13   Insured means:

                 a.  The Person designated on the face of this Policy; or

                 b.  any Person to whom coverage has been assigned with the
                     written approval of the Company as provided in Section 3.5
                     resulting in a change in the Insured named on a
                     Certificate in accordance with this Policy.

    B.    Section 2.4 and all references thereto in the Policy are deleted in
          their entirety.

    C.    Section 2.8 is amended to read in its entirety as follows:

          2.8    Cancellation by the Insured of a Certificate ---
                 Notwithstanding any provision to the contrary in this
                 Policy, the Insured shall be obligated to maintain coverage
                 of a Certificate for a Loan and to pay corresponding
                 premiums for continuation of such coverage except that
                 coverage on a Loan may be cancelled by the Insured effective
                 when the unpaid principal balance of the Loan is less than
                 50% of the Value of the Property. Subject to the foregoing
                 obligation of the Insured to maintain coverage, the Insured
                 may obtain cancellation of coverage on a Loan, if permitted,
                 by making a written request to the Company for cancellation.
                 However, no refund on a cancellation of coverage on a Loan
                 will be paid upon cancellation. Cancellation of coverage on
                 a Loan will not cancel this Policy.

    D.    Section 3.5 is amended to read in its entirety as follows:

          3.5    Change of Insured --- Change of Insured shall only be
                 allowed if advance written approval is obtained from the
                 Company (which approval shall be in the sole and absolute
                 discretion of the Company). If coverage of a Loan is to be
                 assigned or transferred by the Insured to a new Insured, the
                 Insured shall request the Company's approval thereof and if
                 the Company approves the change of Insured, the Company
                 shall, thereafter, change its records to identify the new
                 Insured for such Loan.

E.       With reference to the Master Reporting Program Endorsement
         (Form #71-7139 (8/94)):

          1.     In the first sentence of Section 2.1 the word

          2.     In the first sentence of the first paragraph of Section
                 2.2(b), the word "contained" is inserted before "in the
                 Loan File" and the words "by the Insured" are deleted;
                 and in the first sentence of the second paragraph, after
                 the words "Certificate or" and before "Loan File" is
                 inserted "contained in the".

          3.     Section 2.4 and all references thereto in the Policy are
                 deleted in their entirety.
