         THIS MORTGAGE LOAN PURCHASE AGREEMENT is made as of September 24, 1998,
by and among THE SELLERS LISTED ON THE SIGNATURE PAGE HERETO (the "Sellers"),
and BANC ONE ABS CORPORATION, its successors and assigns (the "Purchaser").

         WHEREAS, the Sellers and the Purchaser wish to set forth the terms
pursuant to which the Mortgage Loans are to be sold by the Sellers to the
Purchaser and purchased by the Purchaser from the Sellers;

         NOW, THEREFORE, in consideration of the foregoing, the other good and
valuable consideration and the mutual terms and covenants contained herein, the
parties hereto agree as follows:

                                    ARTICLE I

                               CERTAIN DEFINITIONS

         Section 1.01. Certain capitalized terms used in this Agreement are
defined in and shall have the respective meanings assigned them in Article I to
the Pooling and Servicing Agreement, dated as of August 31, 1998, among the
Purchaser, as Depositor, Bank One, N.A., as Servicer and The Bank of New York,
as Trustee (the "Trustee") (the "Pooling and Servicing Agreement"). All
references herein to "the Agreement" or "this Agreement" are to this Mortgage
Loan Purchase Agreement, and all references herein to Articles, Sections and
subsections are to Articles, Sections or subsections of this Mortgage Loan
Purchase Agreement unless otherwise specified.

                                   ARTICLE II

                        CONVEYANCE OF THE MORTGAGE LOANS


         Section 2.01. Conveyance of Mortgage Loans

         (a) Immediately prior to consummation on the Closing Date of the
transactions contemplated by the Pooling and Servicing Agreement, in
consideration of the Purchaser's delivery of cash in the amount of $847,875,000
(which is net of underwriting commission), the Transferor Interest and other
consideration, each Seller does hereby transfer, assign, set over and convey to
the Purchaser without recourse, all of the right, title and interest of such
Seller in and to each Mortgage Loan, including its Principal Balance (including
all Additional Balances) set forth in the applicable Mortgage Loan Schedules
attached hereto as Exhibits B-1, B-2, B-3, B-4, B-5, B-6, B-7, B-8 and B-9,
together with the Mortgage Files relating thereto and all proceeds thereof
received after the Cut-Off Date.

         (b) It is the express intent of the parties hereto that the conveyance
of the Mortgage Loans by the Sellers to the Purchaser as provided in this
Agreement be, and be construed as, a sale of all of the Sellers' right, title
and interest in the Mortgage Loans by the Sellers to the Purchaser and to the
Trustee, as its successor and assignee hereunder. Further, it is not the
intention of the parties that such conveyance be deemed a pledge of the Mortgage
Loans by the Sellers to the Purchaser and to the Trustee, as its successor and
assignee hereunder, to secure a debt or other obligation of the Sellers;
however, in the event that, notwithstanding the


                                       2
   5
intent of the parties, the Mortgage Loans are held to be property of the
Sellers, or if for any reason this Agreement is held or deemed to create a
security interest in the Mortgage Loans, then, (a) this Agreement also shall be
deemed to be, and hereby is, a security agreement within the meaning of Articles
8 and 9 of the Uniform Commercial Code in effect in the applicable state; (b)
the conveyance provided for in this Agreement shall be deemed to be, and hereby
is, a grant by the Sellers to the Purchaser and to the Trustee as its successor
and assignee hereunder of a security interest in and to all of the Sellers'
right, title, and interest, whether now owned or hereafter acquired, in and to:

                  (I) All accounts, contract rights, general intangibles,
         chattel paper, instruments, documents, money, deposit accounts,
         certificates of deposit, goods, letters of credit, advices of credit,
         certificated securities and uncertificated securities consisting of,
         arising from or relating to any of the property described in (A)
         through (D) below: (A) each Mortgage Loan, including (a) the Mortgage
         Note and the related Mortgage and (b) its Principal Balance and all
         Additional Balances and all collections in respect thereof received on
         or after the Cut-Off Date, identified on the Mortgage Loan Schedule as
         defined herein, including all Eligible Substitute Mortgage Loans, (B)
         property that secured a Mortgage Loan that is acquired by foreclosure
         or deed in lieu of foreclosure; (C) the Purchase Agreement, (D) any
         hazard insurance policies in respect of the Mortgage Loans; and (E) the
         amounts on deposit in the Spread Account; and

                  (II) All proceeds of the collateral described in (I).

         (c) The possession by the Trustee or its designee of the Mortgage
Notes, Assignments of Mortgages and such other goods, letters of credit, advices
of credit, instruments, money, documents, chattel paper or certificated
securities shall be deemed to be "possession by the secured party," or
possession by a purchaser or a person designated by him or her, for purposes of
perfecting the security interest pursuant to the Uniform Commercial Code
(including, without limitation, Sections 9-305, 8-313 or 8-321 thereof) as in
force in the relevant jurisdiction; and (d) notifications to persons holding
such property, and acknowledgments, receipts or confirmations from persons
holding such property, shall be deemed to be notifications to, or
acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of the Trustee or its designee for the purpose
of perfecting such security interest under applicable law. Subject to the
provisions of the Pooling and Servicing Agreement permitting the Servicer to
commingle amounts collected with respect to the Mortgage Loans with other
general collections of the Servicer, the Sellers and the Trustee at the
direction of the Purchaser to the extent consistent with this Agreement, shall
take such actions as may be necessary to ensure that, if this Agreement were
deemed to create a security interest in the Mortgage Loans and the proceeds
thereof, such security interest would be deemed to be a perfected security
interest of first priority under applicable law and will be maintained as such
throughout the term of the Agreement. In connection herewith, the Trustee shall
have all of the rights and remedies of a secured party and creditor under the
Uniform Commercial Code as in force in the relevant jurisdiction.

         Section 2.02. Possession of Mortgage Files

         (a) Upon the delivery to each Seller of the consideration set forth in
Section 2.01, the ownership of each Seller's Mortgage Notes, related Mortgages
and the contents of the related Mortgage Files are vested in the Purchaser.

         (b) Pursuant to Section 2.04, each Seller has delivered or caused to be
delivered each Mortgage File with respect to the Mortgage Loans transferred by
it to the Purchaser.

         Section 2.03. Books and Records

         The transfer of each Mortgage Loan to the Purchaser shall be reflected
on the related Seller's balance sheets and other financial statements as a sale
of assets by such Seller. Each Seller shall be responsible for maintaining, and
shall maintain, a complete set of books and records for each Mortgage Loan which
shall be clearly marked to reflect the ownership of each Mortgage Loan by the
Purchaser.

         Each Seller hereby confirms to the Trustee that it has caused the
portions of the Electronic Ledgers relating to the Mortgage Loans to be clearly
and unambiguously marked, and has made the appropriate entries in its general
accounting records, to indicate that such Mortgage Loans have been transferred
to or at the direction of the Purchaser.

         Section 2.04. Delivery of Mortgage Loan Documents

         Each Seller shall deliver or cause to be delivered within 90 days of
the Closing Date to the Purchaser or its designee, in accordance with the
instructions of the Purchaser, and pursuant to Section 2.01 of the Pooling and
Servicing Agreement, each original Mortgage Note, endorsed at the direction of
the Purchaser by the applicable Seller, on its face or by allonge attached
thereto, without recourse, in blank or to the order of the Trustee in the
following form: "Pay to the order of The Bank of New York, as trustee for the
registered holders of Banc One HELOC Trust 1998-1, HELOC Asset-Backed
Certificates, Series 1998-1, without recourse, representation or warranty,
express or implied," and an original Assignment of Mortgage endorsed in blank
prepared in recordable form; provided, however, that as to any Mortgage Loan, if
(a) as evidenced by an Opinion of Counsel delivered to and in form and substance
satisfactory to the Trustee and the Credit Enhancer, (x) an optical image or
other representation of the related documents specified above are enforceable in
the relevant jurisdictions to the same extent as the original of such document
and (y) such optical image or other representation does not impair the ability
of an owner of such Mortgage Loan to transfer its interest in such Mortgage
Loan, and (b) the retention of such documents in such format will not result in
a reduction in the then current rating of the Investor Certificates, without
regard to the Policy, such optical image or other representation may be
delivered to the Trustee or assignee in lieu of the physical documents specified
above.

         Each Seller agrees not to notify the obligors on the Mortgage Loans of
the transfer of the Mortgage Loans to the Purchaser, unless required by the
terms of the Mortgage Loans or applicable law.

   7
         Section 2.05. Acceptance by Purchaser of the Mortgage Loans; Certain
Substitutions; Certification by the Trustee

         (a) The Purchaser agrees to execute and deliver on the Closing Date for
each Mortgage Loan an acknowledgment of receipt of the Mortgage Loans, in the
form attached as Exhibit C hereto, and declares that it will hold the documents
delivered to it pursuant to Section 2.04 and any amendments, replacements or
supplements thereto, as well as any other assets transferred pursuant to the
terms hereof. Pursuant to the Pooling and Servicing Agreement, any Custodial
Agreement and this Agreement, the Trustee (or any Custodian on behalf of the
Trustee) will, for the benefit of the Purchaser and the Credit Enhancer, review
(or cause to be reviewed) each of the documents set forth in Section 2.04 within
90 days following delivery to ascertain that all required documents set forth in
this Section 2.04 have been executed and received, and that such documents
relate to the Mortgage Loans identified on the Mortgage Loan Schedule, and in so
doing the Trustee may rely on the purported due execution and genuineness of any
signature thereon.

         (b) If the Trustee (or any Custodian on behalf of the Trustee) during
the process of reviewing the Mortgage Files finds any document constituting a
part of a Mortgage File which is not executed, has not been received, is
unrelated to the Mortgage Loan identified in the Mortgage Loan Schedule, or
determines that such Mortgage File is otherwise defective in any material
respect, the Trustee is required by the Pooling and Servicing Agreement to
promptly give notice of the same to the Purchaser, the applicable Seller and the
Credit Enhancer to correct or cure such defect. It is understood that the scope
of the Trustee's review of the Mortgage Files is limited solely to confirming
that the documents listed in Section 2.04 have been executed and received and
relate to the Mortgage Files identified in the Mortgage Loan Schedule. The
applicable Seller agrees to use its reasonable efforts to cause to be remedied
any material defect in a document constituting part of a Mortgage File of which
such Seller is so notified by the Purchaser, the Trustee or the Credit Enhancer.
If, however, within 90 days after notice to it respecting such defect, the
applicable Seller has not caused to be remedied the defect or if at any time any
loss is suffered by the Trustee on behalf of the Certificateholders or the
Credit Enhancer, in respect of any Mortgage Loan as a result of a defect in any
document constituting a part of its Mortgage File, then on the next succeeding
Business Day upon the deposit to the Collection Account of the Transfer Deposit
Amount, if any, and upon satisfaction of the applicable conditions described
herein, all right, title and interest of the Trust in and to such Mortgage Loan
shall be deemed to be retransferred, reassigned and otherwise reconveyed,
without recourse, representation or warranty, to the Seller on such Business Day
and the Principal Balance of such Mortgage Loan shall be deducted from the Pool
Balance; provided, however, that interest accrued on the Principal Balance of
such Mortgage Loan to the end of the related Collection Period shall be the
property of the Trust. If the Trustee determines pursuant to the Pooling and
Servicing Agreement that the reduction of such Principal Balance from the Pool
Balance in accordance with the preceding sentence would cause the Transferor
Principal Balance to be less than the Minimum Transferor Interest (a "Transfer
Deficiency") and delivers written notice of such deficiency to the applicable
Seller, then within five Business Days after the Business Day of such retransfer
the applicable Seller shall either (i) substitute an Eligible Substitute
Mortgage Loan or (ii) deposit into the Collection Account an amount (the
"Transfer Deposit Amount") in immediately available funds equal to the Transfer
Deficiency or a combination of both (i) and (ii) above. Such reduction or
substitution and the actual payment of any Transfer Deposit Amount, if any,
shall be deemed to be payment in full for such Mortgage


                                       5
   8
Loan. It is understood and agreed that the obligation of a Seller to accept a
transfer of a Defective Mortgage Loan and to either convey an Eligible
Substitute Mortgage Loan or to make a deposit of any related Transfer Deposit
Amount into the Collection Account shall constitute the sole remedy respecting
such defect available to Certificateholders, the Trustee and the Credit Enhancer
against such Seller.

         Each Seller, promptly following the transfer of a Defective Mortgage
Loan from or the transfer of an Eligible Substitute Mortgage Loan pursuant to
this Section 2.05(b), shall appropriately mark its Electronic Ledger and make
appropriate entries in its general account records to reflect such retransfer.

         Notwithstanding any other provision of this Section 2.05(b), a
retransfer of a Defective Mortgage Loan to a Seller pursuant to this Section
2.05(b) that would cause the Transferor Principal Balance to be less than the
Minimum Transferor Interest shall not occur if such Seller either fails to
convey an Eligible Substitute Mortgage Loan or to deposit into the Collection
Account any related Transfer Deposit Amount required by this Section 2.05(b)
with respect to the transfer of such Defective Mortgage Loan.

         (c) As to any Eligible Substitute Mortgage Loan or Loans, the Seller
shall deliver to the Trustee with respect to such Eligible Substitute Mortgage
Loan or Loans such documents and agreements as are required to be held by the
Trustee in accordance with Section 2.04. For any Collection Period during which
the Seller substitutes one or more Eligible Substitute Mortgage Loans, the
Transfer Deposit Amount (as determined by the Servicer pursuant to the Pooling
and Servicing Agreement) shall be deposited by the Seller in the Collection
Account at the time of substitution. Any amounts received in respect of the
Eligible Substitute Mortgage Loan or Loans during the Collection Period in which
the circumstances giving rise to such substitution occur shall not be a part of
the Trust Fund and shall not be deposited by the Seller in the Collection
Account. All amounts received by the Servicer during the Collection Period in
which the circumstances giving rise to such substitution occur in respect of any
Defective Mortgage Loan so removed by the Trust Fund shall be deposited by the
Servicer in the Collection Account. Upon such substitution, the Eligible
Substitute Mortgage Loan or Loans shall be subject to the terms of this
Agreement in all respects, and the Seller shall be deemed to have made with
respect to such Eligible Substitute Mortgage Loan or Loans, as of the date of
substitution, the covenants, representations and warranties set forth in Section
3.02. The procedures applied by the Seller in selecting each Eligible Substitute
Mortgage Loan shall not be materially adverse to the interests of the Trustee,
the Certificateholders and the Credit Enhancer.

         Section 2.06. Acceptance by the Purchaser

         The Purchaser acknowledges the assignment to it of the Mortgage Loans
being transferred hereby by the related Sellers and the delivery of the Mortgage
Files to it or upon its order and, concurrently with such delivery, has
delivered to or upon the order of the related Sellers, in exchange for such
Mortgage Loans and the related Mortgage Files, cash and other consideration as
set forth in Section 2.01.

         Section 2.07. The Closing

         The conveyance of the Mortgage Loans shall take place at the offices of
Orrick, Herrington & Sutcliffe LLP, 666 Fifth Avenue, New York, New York 10103,
on the Closing Date, immediately prior to the closing of the transactions
contemplated by the Pooling and Servicing Agreement and the Underwriting
Agreement.

         With respect to the representations and warranties set forth in this

discovered by such Seller, the Purchaser, the Servicer or a Responsible Officer
of the Trustee that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan then, notwithstanding such Seller's lack of knowledge with
respect to the substance of such representation and warranty being inaccurate at
the time the representation or warranty was made, such inaccuracy shall be
deemed a breach of the applicable representation or warranty and subject such
Seller to the obligations set forth in Section 3.03.

         Section 3.03. Purchase and Substitution

         It is understood and agreed that the representations and warranties set
forth in Sections 3.01 and 3.02 shall survive delivery of the Mortgage Loans to
the Purchaser. It is understood and agreed that the Purchaser is making certain
representations and warranties with respect to the Mortgage Loans in the Pooling
and Servicing Agreement and that the Sellers have agreed to cure any breach of
such representations and warranties or to repurchase or substitute 


                                       11
   14
for any affected Mortgage Loan as set forth herein. Upon discovery by a Seller,
the Purchaser, the Servicer or a Responsible Officer of the Trustee of (i) any
breach of the representation and warranty set forth in Section 2.04(b)(vi) of
the Pooling and Servicing Agreement or (ii) a breach of any of the
representations and warranties in Sections 3.01 and 3.02 or the representations
and warranties of the Purchaser with respect to the Mortgage Loans in Section
2.04 of the Pooling and Servicing Agreement that materially and adversely
affects the interests of the Trust or the Investor Certificateholders or the
Credit Enhancer in the related Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties and the Credit Enhancer.
Within 90 days of the earlier of its discovery or its receipt of notice of any
breach of a representation or warranty, the applicable Seller shall cure, such
breach in all material respects, or shall, not later than the Business Day next
preceding the Distribution Date in the month following the Collection Period in
which any such cure period expired (or such later date that is acceptable to the
Trustee and the Credit Enhancer as evidenced by their written consents), either
(a) accept a transfer of such Mortgage Loan from the Trust or (b) substitute an
Eligible Substitute Mortgage Loan in the same manner and subject to the same
conditions as set forth in Section 2.05; provided, however, that the cure for
any breach of a representation and warranty of the Purchaser in Section 2.04 of
the Pooling and Servicing Agreement relating to the characteristics of the
Mortgage Loans in the aggregate shall be a repurchase of or substitution for
only the Mortgage Loans necessary to cause such characteristics to be in
compliance with the related representation and warranty and provided, further,
that each Seller shall contribute proportionally to the repurchase or
substitution of such Mortgage Loans, allocated according to the proportion of
Mortgage Loans contributed by each such Seller to the Trust. Upon accepting such
transfer and making any required deposit into the Collection Account or
substitution of an Eligible Substitute Mortgage Loan, as the case may be, each
Seller shall be entitled to receive an instrument of assignment or transfer from
the Trustee to the same extent as set forth in Section 2.05 with respect to the
transfer of Mortgage Loans under that Section.

         It is understood and agreed that the obligations of any Seller to
accept a transfer of a Mortgage Loan as to which a breach has occurred and is
continuing and to make any required deposit in the Collection Account or to
substitute an Eligible Substitute Mortgage Loan, as the case may be, shall
constitute the sole remedy against such Seller respecting such breach available
to Investor Certificateholders, the Trustee on behalf of Investor
Certificateholders and the Credit Enhancer. Notwithstanding the foregoing, with
regard to any breach of the representation and warranty set forth in Section
3.02(d), the sale and assignment of the affected Mortgage Loans to the Trust
shall be deemed void and the applicable Seller shall pay to the Trust the sum of
the amount of the related Principal Balances, plus unpaid accrued interest on
each such Principal Balance at the applicable Loan Rate to the date of payment.

                                   THE SELLERS

         Section 5.01. [Reserved]

         Section 5.02. Enforceability; Merger or Consolidation of the Sellers

         (a) Each Seller (other than Bank One, Wisconsin, which is a Wisconsin
state bank) will keep in full effect its respective existence, rights and
franchises as a national bank (or state bank, in the case of Bank One,
Wisconsin), and will obtain and preserve its qualification to do business as a
foreign corporation in each jurisdiction in which such qualification is or shall
be necessary to protect the validity and enforceability of this Agreement, the
Pooling and Servicing Agreement, and any of the Mortgage Loans and to perform
its duties under such agreements.

         (b) Any Person into which any Seller may be merged or consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
any Seller shall be a party, or any Person succeeding to the business of any

   16
parties hereto, anything herein to the contrary notwithstanding.

         Section 5.03. Mandatory Sale; Grant of Security Interest

         The sale on the Closing Date by each Seller of its Mortgage Loans is
mandatory, it being specifically understood and agreed that each Mortgage Loan
is unique and identifiable on the date hereof and that an award of money damages
would be insufficient to compensate the Purchaser for the loss and damages
incurred by the Purchaser (including damages to prospective purchasers of the
Certificates) in the event of such Seller's failure to deliver the Mortgage
Loans on or before the Closing Date. Each Seller hereby grants to the Purchaser
and to the Trustee as its successor and assignee a lien on and continuing
security interest in each Mortgage Loan and each document and instrument
evidencing such Mortgage Loan to secure the performance by such Seller of its
obligations hereunder. All rights and remedies of the Purchaser under this
Agreement are distinct from, and cumulative with, any other rights or remedies
under this Agreement or afforded by law or equity, and all such rights and
remedies may be exercised concurrently, independently or successively.

                                   ARTICLE VI

                              ADDITIONAL AGREEMENTS

for the benefit of the Purchaser, the Trustee, the Certificateholders and the
Credit Enhancer that the occurrence of a breach of any of the Sellers'
representations and warranties contained in Section 3.02 hereof shall constitute
events obligating the Seller, to the extent specified in Section 2.04 of the
Pooling and Servicing Agreement, and without further notice from the Purchaser
hereunder, to purchase any Mortgage Loan from the Trustee. It is understood and
agreed that the obligation of any Seller to purchase any Mortgage Loan as to

adversely affects the rights of the Certificateholders under the Pooling and
