Dear Sirs:

     Block Mortgage Finance,  Inc. (the  "Depositor"),  a wholly-owned,  limited
purpose  subsidiary  of  Companion  Mortgage  Corporation   ("Companion"),   has
authorized  the  issuance  and  sale of  Block  Mortgage  Finance  Asset  Backed
Certificates,  Series  1998-1,  Class A-1,  Class A-2,  Class A-3, Class A-4 and
Class A-5 Certificates  (collectively,  the "Fixed Rate Certificates") and Class
A-6  Certificates  (the "Adjustable Rate  Certificates"  and,  together with the
Fixed  Rate  Certificates,  the  "Class  A  Certificates"),   and  the  Class  R
Certificates (the "Class R Certificates").  The Class A Certificates and Class R
Certificates  are herein  collectively  referred to as the  "Certificates".  The
Certificates  evidence in the  aggregate  the  beneficial  interest in a pool of
fixed and adjustable rate mortgage loans (the "Mortgage Loans").  The Fixed Rate
Certificates  will  represent  an undivided  ownership  interest in the group of
Mortgage  Loans (the "Fixed Rate Group") which are secured by  fixed-rate  first
and second mortgages primarily on one- to four-family residential dwellings. The
Adjustable Rate Certificates will represent an undivided  ownership  interest in
the group of Mortgage Loans (the "Adjustable Rate Group" and,  together with the
Fixed Rate Group, the "Loan Groups") which are secured by adjustable-rate  first
mortgages primarily on one- to four-family residential dwellings.







     Only  the  Class  A  Certificates   are  being  purchased  by  the  several
underwriters named in Schedule A hereto (collectively,  the "Underwriters"),  at
the price set forth in Schedule A.

     The  Certificates  will be issued under a pooling and  servicing  agreement
(the "Pooling and Servicing  Agreement"),  dated as of January 1, 1998 among the
Depositor,  Companion,  as  seller  (in  such  capacity,  the  "Seller"),  Block
Financial Corporation,  as master servicer (the "Master Servicer"),  and Bankers
Trust  Company of  California,  N.A.,  as trustee  (the  "Trustee").  The Master
Servicer will enter into a subservicing  agreement,  dated as of January 1, 1998
(the "Sub-Servicing  Agreement"),  with Companion Servicing Company, L.L.C. (the
"Sub-Servicer")  to provide for the sub-  servicing of the Mortgage  Loans.  The
Seller,  pursuant  to the terms of the  Pooling and  Servicing  Agreement,  will
transfer  to the  Depositor  and the  Depositor,  pursuant  to the  Pooling  and
Servicing  Agreement,  will transfer to the Trustee, all of its right, title and
interest in and to the  Mortgage  Loans as of the Cut-Off  Date  (except for (i)
principal  (including  Prepayments) and interest collected on each Mortgage Loan
on or prior to the Cut-Off  Date (other than,  with respect to Actuarial  Loans,
scheduled  monthly  payments  collected  on or prior to the Cut-Off Date and due
after the Cut-Off  Date) and (ii) with  respect to  Actuarial  Loans,  scheduled
monthly  payments  due on or  prior  to the  Cut-Off  Date)  and the  collateral
securing each Mortgage Loan. The Certificates will evidence fractional undivided
interests  in the  property  held in trust for the holders of such  Certificates
(the  "Trust").  The assets of the Trust will include,  among other things:  the
Mortgage Loans to be conveyed by the Depositor to the Trust on the Closing Date;
such  amounts as may be held by the Master  Servicer in the  Collection  Account
(other than  investment  earnings  thereon)  and any other  accounts  held by or
maintained by the Master  Servicer with respect to the servicing of the Mortgage
Loans and the other assets of the Trust;  and such amounts as may be held by the
Trustee in the Distribution Account (other than investment earnings thereon) and
any other accounts held by the Trustee for the Trust.  The aggre- gate undivided
interest in the Trust represented by the Class A Certificates  initially will be
equal to  $184,325,817.06  of principal  (subject to a variance of plus or minus
5%),  which will  represent 100% of the  outstanding  principal  balances of the
Mortgage  Loans  as of  January  1,  1998  (the  "Cut-Off  Date").  The  Class A
Certificates  will  have  the  benefit  of two  certificate  guaranty  insurance
policies  (each,  a  "Policy")   issued  by  MBIA  Insurance   Corporation  (the
"Certificate  Insurer"),  the principal operating subsidiary of MBIA Inc., a New
York Stock  Exchange  listed  company,  pursuant to an Insurance  Agreement (the
"Insurance  Agreement") dated as of January 1, 1998 among the Seller, the Master
Servicer, the Depositor, the Trustee and the Certificate Insurer. In addition to
the Insurance Agreement,  the Seller, the Master Servicer,  the Underwriters and
the  Certificate  Insurer  will enter  into an  Indemnification  Agreement  (the
"Indemnification Agreement") dated as of January 28, 1998. A form of the Pooling
and  Servicing  Agreement  has been  filed  as an  exhibit  to the  Registration
Statement (hereinafter defined).

BWNY03/123624





     An election will be made to treat the assets of the Trust as a "real estate
mortgage  investment  conduit" (a "REMIC") for federal income tax purposes.  The
Class A Certificates will represent  beneficial ownership of "regular interests"
in the REMIC and the Class R Certificates will represent beneficial ownership of
"residual interests" in the REMIC.

     Capitalized terms used but not defined herein shall have the meanings given
to them in the Pooling and Servicing Agreement.

     This  Underwriting  Agreement,  the Pooling and  Servicing  Agreement,  the
Sub-Servicing   Agreement,  the  Insurance  Agreement  and  the  Indemnification
Agreement are referred to collectively  herein as the  "Agreements".  The Master
Servicer,  the Seller and the Depositor are referred to  collectively  herein as
the "Transaction Parties".

     The  Depositor  filed with the  Securities  and  Exchange  Commission  (the
"Commission")  on October 15,  1996, a  registration  statement on Form S-3 (No.
333-14041), including a form of prospectus and prospectus supplement relating to
the Class A Certificates,  and filed with the Commission amendment No. 1 to such
registration  statement  on  December  31,  1996  and  amendment  No.  2 to such
registration  statement  on January 21,  1997,  and  pursuant to the  provisions
hereof shall file such  post-effective  amendments  thereto as may  hereafter be
required  pursuant to the  Securities  Act of 1933, as amended (the "1933 Act"),
and the rules and  regulations  of the  Commission  thereunder  (the  "Rules and
Regulations"). Such registration statement (as amended) is referred to herein as
the "Registration Statement";  the prospectus and prospectus supplement relating
to  the  offering  of the  Class  A  Certificates  constituting  a  part  of the
Registration  Statement  filed or to be filed by the Depositor are  collectively
referred to herein as the "Prospectus" and each of the prospectus and prospectus
supplement  is  referred  to  as  the  "Base  Prospectus"  and  the  "Prospectus
Supplement,"  respectively;  "Amendment No. 1" and "Amendment No. 2" referred to
herein mean the amendment No. 1 to such  Registration  Statement  filed with the
Commission  on December 31, 1996 and the  amendment  No. 2 to such  Registration
Statement filed with the Commission on January 21, 1997,  respectively;  and any
reference herein to any amendment or supplement with respect to the Registration
Statement  or the  Prospectus  shall  be  deemed  to refer  to and  include  any
information  deemed to be a part  thereof  pursuant  to Rule 430A under the 1933
Act.

     SECTION 1.  Representations  and  Warranties  of the Master  Servicer,  the
Seller  and the  Depositor.  Each of the  Master  Servicer,  the  Seller and the
Depositor, as to itself, and the Master Servicer,  individually, with respect to
(a), (b), (o),  (q), (r) and (s) below,  represents  and warrants to, and agrees
with the Underwriters that:

     (a) The Registration Statement, as amended by Amendment No. 1 and Amendment
No. 2, has become effective under the 1933 Act. The

BWNY03/123624





Registration   Statement  complies,  and  all  amendments  to  the  Registration
Statement at the time such amended Registration Statement becomes effective will
comply,  in all material  respects with the requirements of the 1933 Act and the
Rules and Regulations.  The Registration Statement at the time such Registration
Statement  became  effective  did not,  and any  amendment  to the  Registration
Statement at the time such amended Registration Statement becomes effective will
not,  contain  any  untrue  statement  of a  material  fact or omit to state any
material fact required to be stated  therein or necessary to make the statements
therein not  misleading.  The  Prospectus  as of the date hereof  does,  and the
Prospectus as amended or supplemented as of the Closing Date will, comply in all
material  respects  with the  requirements  of the 1933  Act and the  Rules  and
Regulations. The Prospectus as of the date hereof did not, and the Prospectus as
amended or  supplemented  as of the  Closing  Date will not,  contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements  therein,  in the light of the circumstances  under which
they were made, not misleading;  provided, however, that the representations and
warranties in this  subsection  shall not apply to  statements  in, or omissions
from, the Registration  Statement or the Prospectus made in reliance upon and in
conformity  with  information  furnished  to the  Depositor  in  writing  by the
Underwriters or the Certificate  Insurer  expressly for use in the  Registration
Statement  or  Prospectus.  The Seller and the  Depositor  acknowledge  that the
statements  set  forth in the last  paragraph  of the  first  cover  page of the
Prospectus  Supplement,  in the  next to last  paragraph  of page  S-iii  of the
Prospectus  Supplement  and under the caption  "UNDERWRITING"  in the Prospectus
Supplement   constitute  the  only  information  furnished  in  writing  by  the
Underwriters  for inclusion in the Prospectus.  The conditions to the use by the
Depositor  of a  registration  statement  on Form S-3 under the 1933 Act, as set
forth in the General  Instructions to Form S-3, have been satisfied with respect
to the  Registration  Statement  and the  Prospectus.  There are no contracts or
documents of the  Depositor or its  affiliates  that are required to be filed as
exhibits to the Registration Statement pursuant to the 1933 Act or the Rules and
Regulations that have not been so filed on or prior to the effective date of the
Registration Statement.

     (b)  Since the  respective  dates as of which  information  is given in the
Prospectus,  or the Prospectus as amended and  supplemented at the Closing Date,

management,  financial  condition  or  results  of  operations  of  any  of  the
Transaction  Parties or of their  subsidiaries or affiliates,  otherwise than as
set forth in the Prospectus or the Prospectus as amended and supplemented at the
Closing Date.

business as described in the

BWNY03/123624





Prospectus and to enter into and perform its obligations under the Agreements to
which it is a  signatory,  and,  with  respect  to the  Depositor,  to cause the
Certificates to be issued; such Transaction Party is duly qualified as a foreign
corporation  to transact  business and is in good standing in each  jurisdiction
which requires such qualification, except where failure to be so qualified would
not have a material  adverse effect on (A) its business or financial  condition,
(B) its  obligations  under the Agreements to which it is a signatory or (C) the
Owners  of the  Certificates;  such  Transaction  Party is duly  authorized  and
licensed  under  applicable  law,  including,  without  limitation,  those  that
regulate the business of originating, purchasing, selling or servicing first and
second lien mortgage loans, to conduct, in the various jurisdictions in which it
does  business,  the business it currently  conducts  therein and to perform its
obligations as  contemplated  by the  Agreements,  except where failure to be so
qualified  or  licensed  would  not have a  material  adverse  effect on (A) its
business or financial  condition,  (B) its  obligations  under the Agreements to
which it is a signatory or (C) the Owners of the Certificates.

     (d) There are no legal or  governmental  proceedings  pending to which such
Transaction Party is a party, or of which any property of such Transaction Party
is the subject,  which could  reasonably be expected to materially and adversely
affect  (A)  its  financial  position,   shareholders'   equity  or  results  of
operations,  (B) its obligations under the Agreements to which it is a signatory
or (C)  the  Owners  of the  Certificates;  and to the  best  knowledge  of such
Transaction  Party,  no such  proceedings  are  threatened  or  contemplated  by
governmental authorities or threatened by others.

     (e) This  Underwriting  Agreement has been and,  prior to the Closing Date,

authorized, executed and delivered by each Transaction Party which is a party to

thereto,  will  constitute  legal,  valid and  binding  instruments  enforceable
against such  Transaction  Party,  in accordance  with their  respective  terms,
subject  as to  enforceability  (i) to  applicable  bankruptcy,  reorganization,
insolvency,  moratorium  or  other  similar  laws  affecting  creditors'  rights
generally,   (ii)  to  general  principles  of  equity  (regardless  of  whether
enforcement  is sought  in a  proceeding  in  equity  or at law) and (iii)  with
respect  to  rights of  indemnity  under  this  Underwriting  Agreement  and the
Indemnification  Agreement,  to  limitations  of public policy under  applicable
securities laws.

     (f) The issuance and delivery of the Certificates,  the consummation of any
other of the transactions  contemplated in the Agreements and the fulfillment of
the terms of the  Agreements  do not and will not  conflict  with or violate any
term or provision of the Certificate or Articles of  Incorporation  or Bylaws of
such  Transaction  Party;  any statute,  order or regulation  applicable to such
Transaction Party of any court, regulatory body,

BWNY03/123624





administrative  agency  or  governmental  body  having  jurisdiction  over  such
Transaction  Party; and do not and will not conflict with, or result in a breach

indenture,  mortgage,  deed of  trust,  loan  agreement  or other  agreement  or
instrument  to  which  such  Transaction  Party  is a  party  or by  which  such
Transaction Party may be bound or to which any of the property or assets of such
Transaction Party may be subject,  except for conflicts,  violations,  breaches,
accelerations and defaults which would not be, individually or in the aggregate,
materially  adverse to such Transaction  Party or the Owners of the Certificates
or materially adverse to the transactions contemplated by the Agreements.

authorities  or  permits  issued by the  appropriate  state,  federal or foreign
regulatory agencies or bodies necessary to conduct the business now conducted by
it and as  described  in the  Prospectus,  and such  Transaction  Party  has not
received any notice of proceedings relating to the revocation or modification of
any such  license,  certificate,  authority  or permit  which,  singly or in the
aggregate,  if the subject of an unfavorable decision,  ruling or finding, would
materially  and  adversely  affect the conduct of its  business,  operations  or
financial condition.

with respect to Actuarial  Loans,  scheduled  monthly  payments  collected on or
prior to the Cut-Off Date and due after the Cut-Off  Date) and (ii) with respect
to Actuarial  Loans,  scheduled  monthly payments due on or prior to the Cut-Off

necessary,  in the  opinion of any such  counsel  at any such time,  to amend or
supplement  the  Registration  Statement  or the  Prospectus  as then amended or
supplemented  in order to comply  with the  requirements  of the 1933 Act or the
Rules and Regulations thereunder,  or if required by such Rules and Regulations,
including  Rule 430A  thereunder,  to file a  post-effective  amendment  to such
Registration  Statement  (including an amended  Prospectus),  the Depositor will
promptly  prepare and file with the  Commission  such amendment or supplement as
may be  necessary  to correct  such untrue  statement or omission or to make the
Registration  Statement or Prospectus comply with such requirements,  and within
two  Business  Days  will  furnish  to the  Underwriters  as many  copies of the

     (b) The Depositor will give you reasonable  notice of its intention to file

     (c) The Depositor  will notify you  immediately,  and confirm the notice in
writing,  (i)  of  the  effectiveness  of  any  amendment  to  the  Registration
Statement,  (ii) of the mailing or the delivery to the  Commission for filing of
any supplement to the  Prospectus or the Prospectus as amended or  supplemented,

order  suspending  the  effectiveness  of  the  Registration  Statement  or  the
initiation of any  proceedings  for that purpose.  The Depositor will make every
reasonable effort to prevent the issuance of any stop order and, if

any stop order is issued, to obtain the lifting thereof at the earliest possible
moment.

     (d) The Depositor  will deliver to you as many signed and as many conformed
copies of the Registration Statement (as originally filed) and of each amendment
thereto (including exhibits filed therewith or incorporated by reference therein
and documents incorporated by reference in the Prospectus) as you may reasonably
request.

     (e) The Depositor will make  generally  available to holders of the Class A

statement of a firm of independent public  accountants  furnished to the Trustee
pursuant to the Pooling and Servicing Agreement,  as soon as such statements are

     (i) The Depositor  will apply the net proceeds from the sale of the Class A

governmental proceedings instituted or

BWNY03/123624





threatened  against such Transaction Party which could reasonably be expected to
materially and adversely affect the financial condition, shareholders' equity or
results of operations of such  Transaction  Party, or its ability to perform its
obligations  under  the  Agreements,  the  Master  Servicer,  the  Seller or the
Depositor,  as  applicable,  will give  prompt  written  notice  thereof  to the
Underwriters.

     Underwriting Agreement.

         (v) To such counsel's knowledge, and based in part upon the Depositor's
     written  representations  to such counsel,  the  Depositor's  execution and
     delivery of, and its performance of its obligations  under, the Pooling and
     Servicing Agreement, the Insurance Agreement and the Underwriting Agreement
     will not conflict  with,  result in a breach or violation of,  constitute a
     default or an event of  acceleration  under,  or result in the  creation or
     imposition of any lien,  charge or encumbrance  upon the property or assets
     of the  Depositor  pursuant to the terms of, (A) any  indenture,  mortgage,

BWNY03/123624





     administrative  agency or  governmental  instrumentality  applicable to the
     Depositor  which is known to such counsel,  the conflict with which, or the
     breach,  violation,  default,  acceleration  or creation or  imposition  of
     which, would have a material adverse effect on the ability of the Depositor
     to perform its obligations under any of such agreements.  To such counsel's
     knowledge,   and  based  in  part  upon  the  Master   Servicer's   written
     representations  to such  counsel,  the  Master  Servicer's  execution  and
     delivery of, and its performance of its obligations  under,  the Agreements

     Seller's  representations  to such  counsel,  the  Seller's  execution  and
     delivery of, and its performance of its obligations  under, the Pooling and
     Servicing Agreement, the Insurance Agreement and the Underwriting Agreement
     will not conflict  with,  result in a breach or violation of,  constitute a
     default or an event of  acceleration  under,  or result in the  creation or
     imposition of any lien,  charge or encumbrance  upon the property or assets
     of the Seller pursuant to the terms of, (A) any indenture,  mortgage,  deed

     State of Missouri, State of New York or United States court, administrative
     agency or  governmental  instrumentality  applicable to the Seller which is
     known to such counsel,  the conflict with which, or the breach,  violation,
     default,  acceleration  or creation or  imposition  of which,  would have a
     material  adverse  effect  on the  ability  of the  Seller to  perform  its
     obligations  under the  Pooling  and  Servicing  Agreement,  the  Insurance
     Agreement or the Underwriting Agreement.

         (vi) The  direction by the  Depositor  to the Trustee to  authenticate,
     issue  and  deliver  the  Certificates  has  been  duly  authorized  by the
     Depositor,  and the  Certificates,  when  duly  authorized,  authenticated,
     issued and  delivered  by the Trustee and paid for by the  Underwriters  in
     accordance with the Pooling and Servicing Agreement and the Underwriting

BWNY03/123624





     Agreement,  will be validly issued and  outstanding and will be entitled to
     the benefits provided by the Pooling and Servicing Agreement.

         (vii)  To  such  counsel's  knowledge,  and  based  in  part  upon  the
     Depositor's written  representations to such counsel,  the Depositor is not
     required to obtain the consent, approval,  authorization or order of, or to
     register  or file with,  or to give  notice  to, any court or  governmental
     agency or body of the State of Delaware (under the General  Corporation Law
     thereof), the State of Missouri, the State of New York or the United States
     of America in order to execute,  deliver, perform and comply with the terms
     of,  or  for  the   consummation  of  the  transactions  of  the  Depositor
     contemplated  by,  the  Pooling  and  Servicing  Agreement,  the  Insurance
     Agreement  or the  Underwriting  Agreement  except any  consent,  approval,
     authorization, order, registration, filing or notice (A) as may be required
     under  state  securities,  real  estate  syndication  or "blue sky" laws in
     connection  with the offering and sale of the Class A  Certificates  (as to
     which such counsel need  express no opinion  whatsoever)  or (B) which is a
     future obligation of the Depositor pursuant to the terms of the Pooling and
     Servicing Agreement, the Insurance Agreement or the Underwriting Agreement,
     such as, by way of illustration, but not in limitation of the generality of
     the foregoing,  filing or recording a Uniform Commercial Code assignment of
     a  financing  statement  or an  assignment  of Mortgage  with  respect to a
     Mortgage  Loan; or if any such  consent,  approval,  authorization,  order,
     registration,  filing or notice  (not  described  in the  exception  to the
     immediately preceding clause) is required, the Depositor has obtained, made
     or given the same. To such counsel's knowledge,  and based in part upon the
     Master  Servicer's  written  representations  to such  counsel,  the Master
     Servicer is not required to obtain the consent, approval,  authorization or
     order of, to  register  or file  with,  or to give  notice to, any court or
     governmental  agency or body of the State of  Delaware  (under the  General
     Corporation Law thereof),  the State of Missouri,  the State of New York or
     the United  States of America in order to  execute,  deliver,  perform  and
     comply with the terms of, or for the  consummation  of the  transactions of
     the Master  Servicer  contemplated  by, the Agreements  except any consent,

     be required under state securities,  real estate  syndication or "blue sky"
     laws in connection  with the offering and sale of the Class A  Certificates
     (as to which such counsel need express no opinion  whatsoever) or (B) which
     is a future  obligation of the Master Servicer  pursuant to the terms of an
     Agreement,  such as, by way of  illustration,  but not in limitation of the
     generality of the foregoing,  filing or recording a Uniform Commercial Code
     assignment  of a financing  statement  or an  assignment  of Mortgage  with
     respect to a Mortgage  Loan or  obtaining  a consent,  approval or order in
     connection  with  a  foreclosure;   or  if  any  such  consent,   approval,
     authorization, order,

BWNY03/123624





     registration,  filing or notice  (not  described  in the  exception  to the
     immediately  preceding  clause)  is  required,   the  Master  Servicer  has
     obtained, made or given the same. To such counsel's knowledge, and based in
     part upon the Seller's written  representations to such counsel, the Seller
     is not required to obtain the consent, approval, authorization or order of,
     to register or file with,  or to give notice to, any court or  governmental
     agency or body of the State of Delaware (under the General  Corporation Law
     thereof), the State of Missouri, the State of New York or the United States
     of America in order to execute,  deliver, perform and comply with the terms
     of, or for the consummation of the transactions of the Seller  contemplated
     by, the Pooling and Servicing  Agreement,  the  Insurance  Agreement or the
     Underwriting Agreement except any consent, approval, authorization,  order,
     registration,  filing  or  notice  (A)  as  may  be  required  under  state
     securities,  real estate  syndication or "blue sky" laws in connection with
     the offering and sale of the Class A Certificates (as to which such counsel
     need express no opinion  whatsoever) or (B) which is a future obligation of
     the Seller  pursuant to the terms of Pooling and Servicing  Agreement,  the
     Insurance  Agreement  or the  Underwriting  Agreement,  such as,  by way of
     illustration,  but not in  limitation of the  generality of the  foregoing,
     filing or recording a Uniform  Commercial  Code  assignment  of a financing
     statement or an assignment of Mortgage with respect to a Mortgage  Loan; or
     if any such consent, approval,  authorization,  order, registration, filing
     or notice (not  described  in the  exception to the  immediately  preceding
     clause) is required, the Seller has obtained, made or given the same.

         (viii) The Registration  Statement is effective under the 1933 Act, and
     to such counsel's knowledge,  no stop order suspending the effectiveness of
     the  Registration   Statement  has  been  issued  under  the  1933  Act  or
     proceedings therefor initiated or threatened by the Commission.

         (ix)  The  conditions  to the use by the  Depositor  of a  registration
     statement  on Form S-3  under the 1933  Act,  as set  forth in the  General
     Instructions  to  Form  S-3,  have  been  satisfied  with  respect  to  the
     Registration Statement. To such counsel's knowledge, and based in part upon
     the Depositor's  representations to such counsel, there are no contracts or
     documents of any of the Transaction  Parties which are required to be filed
     as exhibits to the Registration  Statement  pursuant to the 1933 Act or the
     Rules  and  Regulations  thereunder  which  have  not  been so  filed.  The
     statements  set  forth in each of the Base  Prospectus  and the  Prospectus
     Supplement  under the captions "RISK FACTORS -- Legal  Considerations"  and
     "ERISA  CONSIDERATIONS" and the statements set forth in the Base Prospectus
     under the caption  "CERTAIN LEGAL ASPECTS OF THE PRIMARY  ASSETS",  in each
     case insofar as such  statements  purport to summarize  matters of state or
     federal law or legal  conclusions with respect thereto,  have been prepared
     or

BWNY03/123624





     reviewed  by such  counsel  and  provide  a fair  summary  of  such  law or
     conclusions.

         (x) To such counsel's knowledge, and based in part upon the Depositor's
     representations to such counsel, there are no actions, suits or proceedings
     against  the  Depositor  (or to which  the  property  of the  Depositor  is
     subject)  pending  or  overtly  threatened  in  writing  before  any court,
     governmental   agency  or  arbitrator  which  (A)  question,   directly  or
     indirectly,  the  validity  or  enforceability  of any of the  Pooling  and
     Servicing Agreement, the Insurance Agreement or the Underwriting Agreement,
     (B) could  reasonably  be expected to materially  and adversely  affect the
     Depositor's financial condition, business or properties taken as a whole or
     the  validity  or   enforceability   of  any  of  such  agreements  or  the
     Certificates  or  (C)  could  reasonably  be  expected  to  materially  and
     adversely  affect the ability of the  Depositor to perform its  obligations
     under any of such  agreements.  To such counsel's  knowledge,  and based in
     part upon the Master Servicer's  representations to such counsel, there are
     no actions,  suits or proceedings  against the Master Servicer (or to which
     the  property  of the  Master  Servicer  is  subject)  pending  or  overtly
     threatened in writing before any court,  governmental  agency or arbitrator
     which (A) question,  directly or indirectly, the validity or enforceability
     of any of the  Agreements,  (B) could  reasonably be expected to materially
     and adversely affect the Master Servicer's financial condition, business or
     properties taken as a whole or the validity or enforceability of any of the
     Agreements  or the  Certificates  or (C) could  reasonably  be  expected to
     materially  and  adversely  affect the  ability of the Master  Servicer  to
     perform its obligations under the Agreements.  To such counsel's knowledge,
     and based in part upon the Seller's  representations to such counsel, there
     are no actions,  suits or  proceedings  against the Seller (or to which the
     property of the Seller is subject) pending or overtly threatened in writing
     before any court,  governmental  agency or  arbitrator  which (A) question,
     directly  or  indirectly,  the  validity  or  enforceability  of any of the
     Pooling  and  Servicing   Agreement,   the   Insurance   Agreement  or  the
     Underwriting Agreement,  (B) could reasonably be expected to materially and
     adversely affect the Seller's financial  condition,  business or properties
     taken  as a  whole  or the  validity  or  enforceability  of  any  of  such
     agreements  or the  Certificates  or (C) could  reasonably  be  expected to
     materially  and  adversely  affect the ability of the Seller to perform its
     obligations under such agreements.

         (xi)  The  Pooling  and  Servicing  Agreement  is  not  required  to be
     qualified  under the Trust Indenture Act, and neither the Depositor nor the
     Trust is required to be registered under the 1940 Act.

         (xii)  In  connection   with  such  counsel's   participation   in  the
     preparation of the Registration Statement and the

BWNY03/123624





     Prospectus,  such  counsel  need not  independently  verify  the  accuracy,
     completeness or fairness of the statements contained therein,  and, without
     limiting the generality of the  foregoing,  such counsel need not, with the
     opinion recipients' consent, review any loan files relating to the Mortgage
     Loans.  The  limitations  inherent in such counsel's  participation  in the
     preparation  of the  Registration  Statement  and  the  Prospectus  and the
     knowledge  available  to such  counsel are such that such  counsel need not
     assume any responsibility for the accuracy, completeness or fairness of the
     statements  contained in the Registration  Statement or the Prospectus.  On
     the  basis  of  such  counsel's  participation  in the  preparation  of the
     Registration  Statement  and the  Prospectus  as  described  above and such
     counsel's  participation  in conferences and telephone  conversations  with
     representatives  of the Depositor,  the Seller,  the Master  Servicer,  the
     Underwriters and others at which the contents of the Registration Statement
     and the Prospectus were discussed, and relying as to facts necessary to the
     determination  of materiality,  to the extent such counsel may do so in the
     exercise  of  such   counsel's   professional   responsibility,   upon  the
     certificates  and statements of officers and other  representatives  of the
     Depositor,  the Seller, the Master Servicer and others, such opinion letter
     will state that no facts have come to such  counsel's  attention  that lead
     such  counsel to believe  that,  as of the date of the  Prospectus  and the
     Closing  Date,   either  the  Registration   Statement  or  the  Prospectus
     (excluding  any  financial  or  statistical  data  contained  therein,  the
     sections of the Base  Prospectus  and the Prospectus  Supplement  captioned
     "FEDERAL  INCOME TAX  CONSEQUENCES",  the  section  of the Base  Prospectus
     captioned  "PLAN  OF  DISTRIBUTION"  and  the  sections  of the  Prospectus
     Supplement  captioned  "COMPANION  SERVICING  COMPANY,   L.L.C.",   "CREDIT
     ENHANCEMENT -- Certificate Insurance Policies",  "CREDIT ENHANCEMENT -- The

     valid and legally  binding  agreements  of the Trustee and are  enforceable
     against  the  Trustee  in  accordance  with  their  terms,  subject,  as to
     enforcement  of  remedies,  (A)  to  applicable   bankruptcy,   insolvency,
     reorganization  and other  similar laws  affecting  the rights of creditors

     such enforceability is considered in a proceeding in equity or at law).

         (ii) The Trustee has duly executed and  countersigned  the Certificates
     issued on the date thereof on behalf of the Trust.

         (iii) The  execution  and  delivery  by the  Trustee of the Pooling and

     Trustee of its  obligations  thereunder do not conflict with or result in a
     violation of the Articles of Association or Bylaws of the Trustee.

         (iv) The  Trustee has full power and  authority  to execute and deliver
     the Pooling and  Servicing  Agreement  and the  Insurance  Agreement and to

     proceedings or  investigations  pending or threatened  against or affecting
     the Trustee before or by any court,  arbitrator,  administrative  agency or

     and  adversely  affect  the  ability  of  the  Trustee  to  carry  out  the
     transactions  contemplated  in the Pooling and Servicing  Agreement and the
     Insurance Agreement.

         (vi)  No  consent,  approval  or  authorization  of,  or  registration,
     declaration or filing with, any court or governmental agency or body of the
     United  States  of  America  or any  state  thereof  is  required  for  the
     execution,  delivery  or  performance  by the  Trustee of the  Pooling  and
     Servicing Agreement and the Insurance Agreement.

     (e) The Underwriters shall have received the favorable opinion or opinions,
dated the Closing  Date,  of Brown & Wood LLP, as counsel for the  Underwriters,
with  respect to the  issuance of the Class A  Certificates  and the sale of the
Class A Certificates to the

BWNY03/123624





Underwriters,  the Registration  Statement,  this  Underwriting  Agreement,  the
Prospectus and such other related matters as the Underwriters may require.

     (f) The Underwriters shall have received the favorable  opinion,  dated the
Closing Date, of Kutak Rock,  special  counsel for the Certificate  Insurer,  in
form and scope satisfactory to counsel for the Underwriters, to the effect that:

         (i) The  Certificate  Insurer is a stock  insurance  corporation,  duly
     incorporated  and validly existing under the laws of the State of New York.
     The Certificate Insurer is validly licensed and authorized to issue each of
     the  Policies  and perform its  obligations  under each of the  Policies in
     accordance with the terms thereof, under the laws of the State of New York.

         (ii) The execution and delivery by the  Certificate  Insurer of each of
     the  Policies,  the Insurance  Agreement and the Insurance  Indemnification
     Agreement are within the corporate  powers of the  Certificate  Insurer and
     have been authorized by all necessary  corporate  action on the part of the
     Certificate Insurer; each of the Policies has been duly executed and is the
     valid and binding  obligation of the  Certificate  Insurer  enforceable  in
     accordance  with its terms except that the  enforcement of the Policies may
     be limited by laws  relating  to  bankruptcy,  insolvency,  reorganization,
     moratorium, receivership and other similar laws affecting creditors' rights
     generally and by general principles of equity.

         (iii) The  Certificate  Insurer is  authorized to deliver the Insurance
     Agreement  and the  Insurance  Indemnification  Agreement  and  each of the
     Insurance  Agreement and the Insurance  Indemnification  Agreement has been
     duly  executed  and is a valid and binding  obligation  of the  Certificate
     Insurer   enforceable  in  accordance   with  its  terms  except  that  the
     enforcement  of the Insurance  Agreement and the Insurance  Indemnification
     Agreement  may be  limited  by laws  relating  to  bankruptcy,  insolvency,
     reorganization,  moratorium,  receivership and other similar laws affecting
     creditors' rights generally and by general principles of equity and, in the
     case   of  the   Insurance   Indemnification   Agreement,   public   policy
     considerations  as to rights of  indemnification  for violations of federal
     and state securities laws.

         (iv) No  consent,  approval,  authorization  or order  of any  state or
     federal court or governmental agency or body is required on the part of the
     Certificate  Insurer, the lack of which would adversely affect the validity
     or  enforceability of any of the Policies,  the Insurance  Agreement or the
     Insurance  Indemnification  Agreement; to the extent required by applicable
     legal   requirements   that  would   adversely   affect  the   validity  or
     enforceability of either of the Policies, the form

BWNY03/123624





     of each  of the  Policies  has  been  filed  with,  and  approved  by,  all
     governmental  authorities having  jurisdiction over the Certificate Insurer
     in connection with the Policies.

         (v) To the extent that either of the  Policies  constitutes  a security
     within the meaning of Section  2(1) of the 1933 Act, it is a security  that
     is exempt from the registration requirements of the 1933 Act.

         (vi)  The   information   set   forth   under   the   caption   "CREDIT
     ENHANCEMENT--Certificate  Insurance Policies" in the Prospectus Supplement,
     insofar  as such  statements  constitute  a  description  of the  Policies,
     accurately summarizes the Policies.

     (g) The  Underwriters  shall have  received an  opinion,  dated the Closing

Poor's, Moody's and the Underwriters,  relating to the true sale of the Mortgage
Loans  (i) by the  Seller  to the  Depositor  and (ii) by the  Depositor  to the
Trustee.

     (h)  Each  of  the   Transaction   Parties  shall  have  furnished  to  the
Underwriters  a  certificate  signed on behalf of such  Transaction  Party by an
accounting or financial  officer thereof,  dated the Closing Date, as to (i) the
accuracy of the  representations and warranties herein of such Transaction Party
at and as of the  Closing  Date;  (ii)  there  being no  legal  or  governmental
proceedings pending,  other than those, if any, referred to in the Prospectus or
the  Prospectus  as amended or  supplemented,  as the case may be, to which such
Transaction  Party is a party or of which any property of such Transaction Party
is the  subject,  which,  in the  judgment  of such  Transaction  Party,  have a
reasonable likelihood of resulting in a material adverse change in the financial
condition,  shareholders'  equity or results of operations  of such  Transaction
Party or  having a  material  adverse  effect  on the  ability  to  perform  its
obligations  under  the  Agreements;  and to the  best  knowledge  of each  such
Transaction  Party,  no such  proceedings  are  threatened  or  contemplated  by
governmental  authorities or threatened by others; (iii) the performance by such
Transaction Party of all of its respective obligations hereunder to be performed
at or  prior to the  Closing  Date;  and  (iv)  such  other  matters  as you may

the  Trustee,  signed by one or more duly  authorized  officers of the  Trustee,

the Pooling and  Servicing  Agreement by the Trustee and the  acceptance  by the
Trustee of the trust created by the Pooling and Servicing  Agreement and the due
execution and delivery of the  Certificates  by the Trustee  thereunder and such
other matters as you shall reasonably request.

BWNY03/123624





     (j) The  Indemnification  Agreement  shall  have been  entered  into by the
Certificate  Insurer,  the Seller, the Master Servicer and the Underwriters,  in
which the Certificate  Insurer will represent to the  Underwriters,  among other
representations,   that  (i)  the   information   under  the  captions   "CREDIT
ENHANCEMENT--Certificate   Insurance  Policies"  and  "CREDIT   ENHANCEMENT--The
Certificate  Insurer" (the "Insurer  Information") in the Prospectus  Supplement
was approved by the  Certificate  Insurer and is limited and does not purport to
provide the scope of  disclosure  required to be included in a prospectus  for a
registrant  under the 1933 Act, in connection  with the public offer and sale of
securities  of such  registrant.  Within such limited scope of  disclosure,  the
Insurer  Information does not contain any untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading;  and (ii) there
has been no change in the financial  condition of the Certificate  Insurer since
September 30, 1997 which would have a material adverse effect on the Certificate
Insurer's  ability  to  meet  its  obligations  under  the  Policies;   and  the
Indemnification  Agreement shall contain provisions,  reasonably satisfactory to
the Underwriters, for the indemnification of the Underwriters.

     (k) The Policies shall have been issued by the Certificate Insurer pursuant
to the  Insurance  Agreement  and  shall  have  been  duly  countersigned  by an
authorized agent of the Certificate Insurer, if so required under
applicable state law or regulation.

     (l) The Class A  Certificates  shall  have been rated  "AAA" by  Standard &
Poor's and "Aaa" by Moody's.

     (m)  Counsel  to  the  Transaction  Parties  shall  have  furnished  to the
Underwriters  any  opinions  supplied  to  Standard  &  Poor's,  Moody's  or the
Certificate Insurer relating to the Class A Certificates and such opinions shall
state that the Underwriters may rely thereon.

     (n) The Underwriters shall have received from each of Deloitte & Touche LLP
and Ernst & Young LLP, certified public accountants,  a letter,  dated as of the
date of the Prospectus Supplement in the form heretofore agreed to.

     (o)  Prior to the  Closing  Date,  Brown & Wood  LLP,  as  counsel  for the
Underwriters, shall have been furnished with such documents and opinions as they
may  reasonably  require  for the  purpose  of  enabling  them to pass  upon the
issuance of the Class A Certificates and the sale of the Class A Certificates to
the Underwriters as herein  contemplated and related  proceedings or in order to
evidence  the  accuracy  and  completeness  of any of  the  representations  and
warranties,  or the fulfillment of any of the conditions,  herein contained; and
all proceedings taken by the Transaction Parties in connection with the issuance
of the  Class A  Certificates  and the sale of the Class A  Certificates  to the
Underwriters as herein

BWNY03/123624





contemplated shall be satisfactory in form and substance to the Underwriters and
Brown & Wood LLP.

     (p)  Since the  respective  dates as of which  information  is given in the
Prospectus, there shall not have been any change, or any development involving a
prospective change, in or affecting the general affairs,  management,  financial
condition,  stockholders'  equity  or  results  of  operations  of  any  of  the
Transaction  Parties or the Certificate  Insurer  otherwise than as set forth or
contemplated in the  Prospectus,  the effect of which is, in the judgment of the
Underwriters, so material and adverse as to make it impracticable or inadvisable
to proceed with the public  offering or the delivery of the Class A Certificates
on the terms and in the manner contemplated in the Prospectus.

     (q)  Subsequent  to  the  execution  and  delivery  of  this   Underwriting
Agreement,  there shall not have occurred any  downgrading  in the rating of any
securities of the Transaction Parties or the Certificate  Insurer, or any public
announcement that any rating  organization has under  surveillance or review its
rating of any securities of any of the  Transaction  Parties or the  Certificate
Insurer (other than an  announcement  with positive  implications  of a possible
upgrade, and no implication of a possible downgrade, of such rating).

     (r) Prior to the Closing Date, each of the  Transaction  Parties shall have
furnished to you such further information, certificates and documents as you may
reasonably request.

     If any condition  specified in this Section 6 shall not have been fulfilled
when  and as  required  to be  fulfilled,  this  Underwriting  Agreement  may be
terminated  by you by  notice  to the  Depositor  at any time at or prior to the
Closing Date, and such  termination  shall be without  liability of any party to
any other party except as provided in Section 7.

     SECTION 7. Payment of Expenses.  Block Financial  Corporation agrees to pay
all  expenses  incident  to  the  performance  of  its  obligations  under  this
Agreement,  including without  limitation those related to (i) the filing of the

first  $10,000  of fees and  expenses,  of Brown and Wood LLP,  as  special  tax
counsel for the  Depositor,  (v) the  qualification  of the Class A Certificates
under  state  securities  and  "blue  sky"  laws  and the  determination  of the
eligibility  of the Class A Certificates  for investment in accordance  with the
provisions of subsection 5(f) of this Underwriting  Agreement,  including filing
fees, (vi) the printing and delivery to the Underwriters,  in such quantities as
you may reasonably request, of copies of the Registration Statement and the

BWNY03/123624





Prospectus  and all  amendments  and  supplements  thereto,  and of any Blue Sky
Survey,  (vii) the delivery to the  Underwriters,  in such quantities as you may
reasonably  request,  of copies of the  Agreements,  (viii) the fees  charged by
nationally  recognized  statistical  rating  agencies  for  rating  the  Class A
Certificates,  (ix) the  reasonable  fees and  expenses  of the  Trustee and its
counsel and (x) the reasonable fees and expenses of the Certificate  Insurer and

provisions of Section 6, the Master Servicer, the Seller and the Depositor shall
reimburse you for all reasonable out-of-pocket expenses,  including the fees and
disbursements of Brown & Wood LLP, as counsel for the Underwriters.

     SECTION  8.  Indemnification.  (a)  Block  Financial  Corporation  and  the
Depositor  jointly  and  severally  agree to  indemnify  and hold  harmless  the
Underwriters and each person,  if any, who controls the Underwriters  within the

     therein not  misleading  or arising out of any untrue  statement or alleged
     untrue  statement of a material fact  contained in the  Prospectus  (or any
     amendment  or  supplement  thereto)  or the  omission  or alleged  omission
     therefrom  of a material  fact  necessary  in order to make the  statements
     therein,  in light of the  circumstances  under  which they were made,  not
     misleading,  unless (a) such untrue statement or omission or alleged untrue
     statement  or omission  was made in reliance  upon and in  conformity  with

     Certificate Insurer expressly for use in the Registration Statement (or any
     amendment  thereto),  or (b) such untrue  statement  or omission or alleged
     untrue  statement or omission was made in any  preliminary  prospectus  and
     corrected  in the  Prospectus  and (A) any  such  loss,  claim,  damage  or

     whatsoever  based upon any such untrue  statement or omission,  or any such
     alleged untrue  statement or omission,  if such settlement is effected with
     the written consent of the Depositor; and

         (iii) against any and all reasonable expense whatsoever  (including the
     reasonable fees and  disbursements  of counsel chosen by you) as reasonably

20 of the 1934 Act (each,  an  "Indemnified  Party")  against  any and all loss,
liability,  claim, damage and expense,  as incurred,  described in the indemnity
contained  in  subsection  (a)(i) of this  Section 8,  arising out of any untrue

damage and  expense,  as  incurred,  described  in the  indemnity  contained  in
subsection  (a)(ii) of this Section 8, arising out of any untrue  statements  or
omissions, or alleged

BWNY03/123624





untrue statements or omissions,  made in the Computational Materials (as defined
below)  prepared  and used by such  Underwriter;  provided,  however,  that such
Computational  Materials  shall not include any Mortgage  Loan  Information  (as
defined below) or any errors in the mathematical  calculations reflected in such
Computational Materials to the extent such errors result from such Mortgage Loan
Information;  and provided,  further, that any such omission or alleged omission
relating to the  Computational  Materials  shall be  determined  by reading such
Computational  Materials  in  conjunction  with the  Prospectus  as an  integral
document and in light of the  circumstances  under which such  statements in the
Computational Materials and the Prospectus were made.  "Computational Materials"
shall mean the "Computational  Materials" as defined in the No- Action Letter of
May 20, 1994 issued by the Commission to Kidder,  Peabody Acceptance Corporation
I, Kidder,  Peabody & Co.  Incorporated and Kidder Structured Asset Corporation,
the  No-Action  Letter of May 27,  1994 issued by the  Commission  to the Public

Commission to the Public Securities  Association (the "SEC No-Action  Letters").
"Computational  Materials" shall include only those Computational Materials that
have been prepared or delivered to prospective  investors by or at the direction
of the Underwriters.  In connection with the use of Computational Materials, the
Underwriters shall comply with all applicable  requirements of the SEC No-Action
Letters.  "Mortgage Loan  Information"  shall mean  information  relating to the

Underwriters are based. All information included in the Computational  Materials
shall be generated based on  substantially  the same methodology and assumptions
that are used to generate the  information in the  Prospectus  Supplement as set
forth therein;  provided,  however, that the Computational Materials may include
information  based on  alternative  methodologies  or  assumptions  if specified
therein.  The Depositor will timely file with the Commission in current  reports
on Form 8-K under the 1934 Act all information  with respect to the Certificates
which constitutes  Computational  Materials,  in accordance with and in the time
frames set forth in the SEC No-Action Letters; and provided,  further,  that the
Depositor  shall not be obligated to file any  Computational  Materials with the
Commission  that (i) in the  reasonable  determination  of the Depositor and the
Underwriters are not required to be filed pursuant to the SEC No-Action  Letters
or (ii) have been determined to contain any material error or omission, provided
that, at the request of an  Underwriter,  the Depositor will file  Computational
Materials   that  contain  a  material  error  or  omission  if  clearly  marked
"superseded  by  materials  dated   [________]"  and  accompanied  by  corrected
Computational  Materials that are marked "material previously dated [_________],
as corrected".

     (c) Each  indemnified  party shall give prompt notice to each  indemnifying
party of any action commenced against it with respect

BWNY03/123624





to which  indemnity  may be  sought  hereunder,  but  failure  to so  notify  an
indemnifying  party  shall not relieve it from any  liability  which it may have
hereunder unless it has been materially  prejudiced by such failure to notify or
from any liability which it may have otherwise than on account of this indemnity
agreement.  An  indemnifying  party may  participate  at its own  expense in the
defense of such action. In no event shall the indemnifying parties be liable for
the fees and  expenses of more than one counsel for all  indemnified  parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction  arising out of the same general allegations or circumstances,
unless  (i) if the  defendants  in any such  action  include  one or more of the
indemnified  parties  and  the  indemnifying  party,  and  one  or  more  of the
indemnified parties shall have employed separate counsel after having reasonably
concluded  that  there may be legal  defenses  available  to it or them that are
different from or additional to those available to the indemnifying  party or to
one or more of the other  indemnified  parties  or (ii) the  indemnifying  party
shall not have employed counsel reasonably satisfactory to the indemnified party
to represent the indemnified  party within a reasonable time after notice of the
commencement of the action.

     SECTION  9.  Contribution.  In order  to  provide  for  just and  equitable
contribution in circumstances in which the indemnity  agreement  provided for in
Section 8 is for any reason held to be unenforceable by the indemnified  parties
although  applicable in accordance with its terms,  Block Financial  Corporation
and the Depositor,  on the one hand, and the Underwriters,  on the other,  shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature  contemplated by said indemnity agreement incurred by Block Financial
Corporation and/or the Depositor and one or more of the Underwriters (i) in such
proportion  as shall be  appropriate  to reflect the relative  benefits to Block
Financial Corporation and the Depositor,  on the one hand, and the Underwriters,
on the  other,  in  connection  with the  matter  to which  the  indemnification
relates,   which  relative  benefits  shall  be  deemed  to  be  such  that  the
Underwriters shall be responsible for that portion represented by the percentage
that the  underwriting  discount on the cover of the  Prospectus  on the Closing
Date bears to the initial public  offering price for the Class A Certificates as
set forth thereon,  and Block  Financial  Corporation and the Depositor shall be
jointly and  severally  responsible  for the  balance or (ii) if the  allocation
provided by clause (i) above is not  permitted  by  applicable  law or otherwise
prohibited  hereby, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
Block  Financial  Corporation  and  the  Depositor,  on the  one  hand,  and the
Underwriters or Underwriter, as applicable, on the other, in connection with the
statements  or  omissions  that  resulted  in such  losses,  claims,  damages or
liabilities,  or  actions  in  respect  thereof,  as well as any other  relevant
equitable considerations; provided, however, that no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person

BWNY03/123624





who was not guilty of such fraudulent misrepresentation. Relative fault shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information  supplied by Block Financial  Corporation
or the Depositor,  on the one hand, or the Underwriters,  on the other hand, and
the parties' relative intent,  knowledge,  access to information and opportunity
to correct  or prevent  such  untrue  statement  or  omission.  Block  Financial
Corporation,  the Depositor and the Underwriters agree that it would not be just
and equitable if contributions  pursuant to this Section 9 were to be determined
by pro rata allocation (even if the Underwriters  were treated as one entity for
such  purpose)  or by any other  method of  allocation  which does not take into
account the equitable  considerations  referred to in the first sentence of this
Section 9. The amount  paid by an  indemnified  party as a result of the losses,
claims,  damages or liabilities (or actions in respect  thereof)  referred to in
the first  sentence  of this  Section 9 shall be deemed to include  any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating, preparing to defend or defending against any action or claim that
is the subject of this Section 9. Notwithstanding the provisions of this Section
9, no  Underwriter  shall be required to contribute  any amount in excess of the
amount by which the total underwriting  commission  received by such Underwriter
for the sale of the Class A Certificates  underwritten  by such  Underwriter and
distributed  to the  public  exceeds  the  amount  of  any  damages  which  such
Underwriter  has  otherwise  been  required  to pay in respect  of such  losses,
liabilities, claims, damages and expenses. The Underwriters' obligations in this
Section  9  to  contribute  are  several  in  proportion  to  their   respective
underwriting  obligations  and not joint.  Each party  entitled to  contribution
agrees that upon the service of a summons or other initial legal process upon it
in any action  instituted  against it in  respect to which  contribution  may be
sought,  it shall  promptly give written  notice of such service to the party or
parties from whom contribution may be sought, but the omission so to notify such
party or  parties  of any such  service  shall not  relieve  the party from whom
contribution may be sought for any obligation it may have hereunder or otherwise
(except as  specifically  provided  in Section 8 hereof).  For  purposes of this
Section 9, each person, if any, who controls any Underwriter  within the meaning
of  Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution  as such  Underwriter,  and each  respective  director of
Block Financial  Corporation  and/or the Depositor,  each respective  officer of
Block  Financial  Corporation  and/or the Depositor who signed the  Registration
Statement,  and each person,  if any, who controls Block  Financial  Corporation
and/or the Depositor within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act shall have the same rights to contribution as Block Financial
Corporation and/or the Depositor.

     SECTION 10. Representations, Warranties and Agreements to Survive Delivery.
All representations, warranties and agreements

BWNY03/123624





contained in this  Underwriting  Agreement or any  statement set forth in any of
the certificates of officers of the Master Servicer, the Seller or the Depositor
submitted  pursuant hereto shall remain  operative and in full force and effect,
regardless  of any  investigation  made by or on behalf of the  Underwriters  or
controlling  person  thereof,  or by or on behalf of the  Master  Servicer,  the
Seller or the Depositor and shall survive  delivery of any Class A  Certificates
to the Underwriters.

     SECTION 11. Termination of Agreement.  This Underwriting Agreement shall be
subject  to  termination  by  notice  given by you to the  Depositor  if (i) any
change,  or any  development  involving a  prospective  change,  in or affecting
particularly  the business or  properties of the Trust,  any of the  Transaction
Parties or the Certificate  Insurer which, in your judgment,  materially impairs
the investment  quality of the Class A  Certificates  or makes it impractical or
inadvisable  to market the Class A  Certificates;  (ii) any  downgrading  in the
rating of any  securities of the Trust,  any of the  Transaction  Parties or the
Certificate   Insurer  by  any   "nationally   recognized   statistical   rating
organization"  (as defined for purposes of Rule 436(g)  under the 1933 Act),  or
any public  announcement  that any such  organization has under  surveillance or
review its rating of any securities of the Trust, any of the Transaction Parties
or  the  Certificate   Insurer  (other  than  an   announcement   with  positive
implications  of  a  possible  upgrading,  and  no  implication  of  a  possible
downgrading,  of such rating);  (iii) any suspension or limitation of trading in
securities  generally on the New York Stock Exchange,  or any setting of minimum
prices  for  trading on such  exchange;  (iv) any  suspension  of trading of any
securities  of the Trust,  any of the  Transaction  Parties  or the  Certificate
Insurer on any  exchange  or in the  over-the-counter  market;  (v) any  banking
moratorium declared by federal or New York authorities;  or (vi) any outbreak or
escalation  of major  hostilities  in which the United  States is involved,  any
declaration  of  war  by  Congress,   or  any  other  substantial   national  or
international calamity or emergency if, in your judgment, the effect of any such
outbreak, escalation, declaration, calamity or emergency makes it impractical or
inadvisable to proceed with  completion of the sale of and payment for the Class
A Certificates.  In the event of any such termination, the covenant set forth in
subsection 5(b), the provisions of Section 7, the indemnity  agreement set forth
in Section 8, and the provisions of Sections 9 and 14 shall remain in effect.

     SECTION 12. Default by One of the Underwriters.  If one of the Underwriters
participating  in the public offering of the Class A Certificates  shall fail on
the Closing Date to purchase the Class A  Certificates  which it is obligated to
purchase  hereunder  (the  "Defaulted  Certificates"),  then the  non-defaulting
Underwriter  shall  have  the  right,  within  24  hours  thereafter,   to  make
arrangements  for it, or any other  underwriter,  to purchase all, but not fewer
than all, of the  Defaulted  Certificates  in such amounts as may be agreed upon
and upon the terms herein set forth. If,

BWNY03/123624





however,  you have not completed such  arrangements  within such 24-hour period,
then:

         (i) if the aggregate  principal  amount of the  Defaulted  Certificates
     does not  exceed  10% of the  aggregate  principal  amount  of the  Class A
     Certificates to be purchased pursuant to this Underwriting  Agreement,  the
     non-defaulting  Underwriter named in this  Underwriting  Agreement shall be
     obligated to purchase the full amount thereof, or

         (ii) if the aggregate  principal  amount of the Defaulted  Certificates
     exceeds 10% of the aggregate  principal  amount of the Class A Certificates
     to be purchased pursuant to this Underwriting Agreement,  this Underwriting
     Agreement  shall  terminate,  without any liability on the part of the non-
     defaulting Underwriter.

     No action taken  pursuant to this Section 12 shall  relieve the  defaulting
Underwriter  from the liability with respect to any default of such  Underwriter
under this Underwriting Agreement.

     In the event of a default by any  Underwriters as set forth in this Section
12,  either you or the Seller  shall have the right to postpone the Closing Date
for a period not exceeding five Business Days in order that any required changes
in the  Registration  Statement  or  Prospectus  or in any  other  documents  or
arrangements may be effected.

     SECTION 13. Notices. All notices and other  communications  hereunder shall
be in  writing  and  shall be  deemed  to have  been  duly  given if  mailed  or
transmitted  by  any  standard  form  of   telecommunication.   Notices  to  the
Underwriters  shall be  directed  to  Morgan  Stanley & Co.  Incorporated,  1585
Broadway,  New York,  New York 10036,  Attention:  Paul Scialabba and to Salomon

Depositor shall be directed to Block Mortgage  Finance,  Inc., 4435 Main Street,

a copy to the Treasurer.

     SECTION 14. Parties. This Underwriting Agreement shall inure to the benefit
of and be binding upon the Underwriters, the Master Servicer, the Seller and the
Depositor,  and their respective  successors.  Nothing expressed or mentioned in
this  Underwriting  Agreement  is intended nor shall it be construed to give any
person, firm or corporation,  other than the parties hereto and their respective
successors and the controlling persons and officers and directors referred to in
Sections  8 and 9 and  their  heirs  and  legal  representatives,  any  legal or
equitable  right,  remedy or claim  under or with  respect to this  Underwriting
Agreement or any provision herein contained. This Underwriting Agreement and all
conditions and  provisions  hereof are intended to be for the sole and exclusive
benefit of the parties and their respective

BWNY03/123624





successors  and said  controlling  persons and officers and  directors and their
heirs and legal  representatives  (to the  extent of their  rights as  specified
herein) and except as provided above for the benefit of no other person, firm or
corporation.  No purchaser  of the Class A  Certificates  from the  Underwriters
shall be deemed to be a successor by reason merely of such purchase.

     SECTION 15.  Governing Law and Time. This  Underwriting  Agreement shall be
governed  by the  law of the  State  of New  York  and  shall  be  construed  in
accordance  with such law  applicable  to  agreements  made and to be  performed
therein,  without  giving  effect to the conflicts of laws  principles  thereof.
Specified times of day refer to New York City time.

     SECTION 16.  Counterparts.  This Underwriting  Agreement may be executed in
counterparts,  each of which  shall  constitute  an  original of any party whose
signature  appears on it, and all of which shall  together  constitute  a single
instrument.


BWNY03/123624

our agreement, please sign and return to us a counterpart hereof, whereupon this
instrument along with all counterparts will become a binding agreement among the
Underwriters,  the Master  Servicer,  the Seller and the Depositor in accordance
with its terms.
