dated as of February 12, 1999 (the "Master Repurchase Agreement"); and

     WHEREAS, Buyer and Seller desire to supplement and amend the Master
Repurchase Agreement to enter into Transactions involving Assets (as defined
below).

     NOW, THEREFORE, the parties hereto agree as follows:


     1.   (a) The first sentence of Section 1 of the Master Repurchase Agreement
shall be amended in its entirety to read as follows:

              "From time to time in Buyer's sole and absolute discretion
          exercised in Good Faith, the parties hereto may enter into
          transactions in which one party ("Seller") agrees to transfer to the
          other ("Buyer") Assets deemed to be Eligible Mortgage Loans by the
          Buyer against the transfer of funds by Buyer, with a simultaneous
          agreement by Buyer to transfer to Seller such Assets at a date certain
          or on demand, against the transfer of funds by Seller."

          (b) Section 1 is hereby further amended by adding the following at the

     the aggregate principal balance of such Mortgage Loans exceeds five percent
     (5%) of the unpaid principal balance of all Purchased Assets constituting

being held in trust for Buyer) (the "Collection Account") with a financial

limitation, under the Related Facilities, in such order as Buyer determines in

          Seller shall service, or supervise the servicing of, the Mortgage

Transactions as set forth in Paragraphs 3(c) or 11 of this Master Repurchase
Agreement, ownership of each Mortgage Loan, including each document in the

to Buyer as set forth in Paragraph 3(a) of this Master Repurchase Agreement and
until termination of any Transactions as set forth in Paragraphs 3(c) or 11 of
this Master Repurchase Agreement and prior to the recordation of the assignments
of mortgage by the Custodian as provided for in the Custody Agreement, record
title in the name of Seller to each Mortgage shall be retained by Seller in
trust, for the benefit of Buyer, for the sole purpose of facilitating the
servicing and the supervision of the servicing of the Mortgage Loans. Nothing in
this Master Repurchase Agreement shall preclude Buyer from engaging in
repurchase transactions with the Purchased Assets or otherwise pledging or
hypothecating the Purchased Assets without the prior consent of Seller, but no
such transaction or provision hereof or provision of the Custody Agreement shall
relieve Buyer of its obligations to transfer Purchased Assets (and, with respect
to the Mortgage Loans, the same Mortgage Loans and not substitutes therefor) to
Seller pursuant and subject to Paragraphs 3, 4 or 11 hereof. Upon termination of
any Transactions as set forth in Paragraph 3(c) of this Master Repurchase
Agreement, Buyer agrees to execute promptly endorsements of the mortgage notes,
assignments of the mortgages and UCC-3 assignments, releases or

without recourse, to Seller and perfect title of like tenor to that conveyed to
Buyer to the related Mortgage Loans. Buyer shall provide reasonable cooperation
in assisting and directing the Custodian to facilitate such preparation (without
material expense to Buyer)".

     custody of any document relating to any Mortgage Loan shall be held by
     Seller in trust for Buyer for purposes of servicing or supervising the
     servicing of such Mortgage Loan and shall not be deemed to constitute
     Seller's retention of custody of the Purchased Assets for purposes of this
     subparagraph".

     17.  Paragraph 9 of the Master Repurchase Agreement is further amended by
adding at the end of the Paragraph the following subparagraphs (c) and (d):

          (c) In the case of any Transaction for which the Repurchase Date is
     other than the business day immediately following the Purchase Date and
     with respect to which Seller does not have any existing right to substitute
     substantially the same Assets for the Purchased Assets, Seller shall have
     the right, subject to the proviso to this sentence, upon notice to Buyer,
     which notice shall be given at or prior to 4:00 p.m. (New York time) on the
     preceding business day, to substitute substantially the same Assets for any
     Purchased Assets; provided, however, that Buyer, in its sole and absolute
     discretion, may elect, by the close of business on the business day next
     following the business day on which notice is received, not to accept such
     substitution.  In the event such substitution is accepted by Buyer, such
     substitution shall be made by Seller's transfer to Buyer of additional
     Mortgage Loans (including the transfer of the related Mortgage Files to the
     Custodian and the issuance to the Buyer of the related Trust Receipt and
     Delivery Confirmation) and Buyer's transfer to Seller of such Assets and
     the related Trust Receipt and Delivery Confirmation, if any, and after
     substitution, the substituted additional Mortgage Loans shall be deemed to
     be Purchased Assets.  In the event Buyer elects not to accept such
     substitution, Buyer shall offer the Seller the right to terminate the
     Transaction.  If the Seller elects to terminate such Transaction (which
     election shall be made in writing within five (5) business days of Buyer's
     offer to Seller of the right to terminate the transaction), the date of
     termination will be determined in accordance with Paragraph 3(c).

          (d) In the event Seller exercises its right to substitute or terminate
     pursuant to subparagraph (c), Seller shall be obligated to pay to Buyer, by
     the close of the business day of such substitution or termination, as the
     case may be, an amount equal to (A) Buyer's actual cost (including all
     fees, expenses and commissions) of (i) entering into replacement
     transactions; and (ii) entering into or terminating hedge transactions, (B)
     to the extent Buyer determines not to enter into replacement transactions,
     the loss incurred by Buyer directly arising or resulting from such
     substitution or termination and (C) in the 

                                       10

     case of the termination of any Transaction, the related Repurchase Price

     Assets by Seller to Buyer and the transfer of the Purchase Price by Buyer
     to Seller, or, in the event that any Transaction is deemed to constitute a
     loan, contemporaneously with the grant of the security interest in the
     Collateral by Seller to Buyer pursuant to Paragraph 6 hereof and the
     transfer of the consideration therefor, consisting of the extension of the
     Purchase Price, which represents the loan proceeds, by Buyer to Seller".

               any Servicing Agreement between Buyer and Seller or (b) amendment
               of any Servicing Agreement without the prior written consent of
               Buyer, (c) transfer by Seller of any of its servicing obligations
               with respect to any Purchased Assets or (d) failure by Seller (if
               it is the Servicer) or any Servicer to service the Mortgage Loans
               (i) in accordance with the standards set forth in the Servicing
               Agreement or (ii) industry standards for similar loans owned by
               third parties;

         (x)   Any other default by Seller of its obligations hereunder which is
               not cured within two (2) days following Seller's receipt of
               written notice from Buyer specifying such default;

     Related Facilities it has executed and delivered to Buyer or any affiliate

          "(j)  As to Transactions in which the defaulting party is acting as
Seller, Buyer may, in its sole and absolute discretion, (i) terminate any
Servicing Agreements without any liability to Seller or the applicable Servicer
(including, without limitation, without liability for 

                                       12

the payment of fees or other sums due and owing to Seller in its capacity as
Servicer) and (ii) transfer servicing responsibility for any Mortgage Loans to
any third party servicer Buyer selects.

          (k) The parties hereto recognize that Seller's obligations to Buyer
under this Master Repurchase Agreement are special, unique and of extraordinary
character. If an Event of Default occurs hereunder, Seller agrees that Buyer may
enforce this Master Repurchase Agreement by a proceeding for specific
performance or other equitable remedy including, without limitation, a
proceeding in which replevin or injunction is sought by Buyer. Seller hereby
waives to the fullest extent permitted by law any and all rights it may have by
statute, constitution or otherwise, to (a) assert the defense of adequacy of a
remedy at law that might be asserted as a bar to any such proceeding, (b) the
fixing, imposition or posting of a bond or other security by Buyer as a
condition to obtaining any equitable relief sought by Buyer, which relief Seller
further agrees may be obtained ex parte without prior notice to Seller provided
a hearing is subsequently provided Seller within a reasonable time after any ex
parte relief may be granted Buyer. Seller further agrees that the rights and
remedies hereunder are cumulative, and are not exclusive of any rights, powers,
privileges, or remedies, now or hereafter existing, at law, or in equity or
otherwise."

                     authority or arbitration panel, which, if determined

     (a) The Mortgage Loan is a binding and valid obligation of the obligor
thereon, in full force and effect and enforceable in accordance with its terms
except as the same may be limited by (i) bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to
creditors' rights generally and (ii) general principles of equity.

     (b)  The Mortgage Loan is genuine in all respects as appearing on its face
and as represented in the books and records of the Seller and all information
set forth therein is true and correct.

     (c)  The Mortgage Loan is free of any default of any party thereto
(including the Seller), other than as expressly permitted pursuant to
subparagraph (d) below, counterclaims, offsets and defenses and from any
rescission, cancellation or avoidance, whether by operation of law or otherwise.

     (d)  No payment under any Mortgage Loan is unpaid more than seventy-five
(75) days past the payment due date set forth in the underlying promissory note
and deed of trust (or mortgage); provided, in no event shall Mortgage Loans
having any payment which is unpaid more than thirty (30) days past the payment
due date set forth in the underlying promissory note and deed of trust (or
mortgage) constitute more than five percent (5%) unpaid principal balance of all
Purchased Assets then owned by Buyer pursuant to the terms of this Agreement.

     (e)  The Mortgage Loan contains the entire agreement of the parties thereto
with respect to the subject matter thereof, has not been modified or amended in
any respect and is free of concessions or understanding with the obligor thereon
of any kind not expressed in writing therein.

     (f)  The Mortgage Loan complies in all respects with the federal Truth-in-
Lending Act and all regulations promulgated thereunder, and complies in all
material respects and was originated in accordance with all other applicable
laws and regulations governing the same, including, without limitation, the
federal Consumer Credit Protection Act, the federal Real Estate Settlement
Procedures Act, the federal Equal Credit Opportunity Act, and the regulations
promulgated thereunder, and all applicable usury laws and restrictions, and all
notices, disclosures and other statements or information required by law or
regulation to be given, and any other act required by law or regulation to be
performed, in connection with the Mortgage Loan have been given and performed as
required.

     (g)  All proceeds of the Mortgage Loan have been fully disbursed and there
is no obligation on the part of the mortgagee to make future advances
thereunder.  Any and all requirements as to completion of any on-site or off-
site improvements and as to disbursements of 

                                       25

any escrow funds therefor have been complied with or are not yet required to be
complied with but will be complied with as and when required. All costs, fees
and expenses incurred in making or closing or recording such Mortgage Loans were
paid.

     (h)  At all times the Mortgage Loans will be free and clear of all liens.

     (i)  The property covered by the Mortgage Loan is insured against loss or
damage by fire and all other hazards normally included within standard extended
coverage in accordance with the provisions of the Mortgage Loan with the Seller
and its successors and assigns named as a loss payee thereon.

     (j)  The property covered by the Mortgage Loan is free and clear of all

     due and payable;

          (iii)  covenants, conditions and restrictions, rights of way,

     the originator of the Mortgage Loan and which (A) are referred to or
     otherwise considered in the appraisal made for the originator of the
     Mortgage Loan or (B) do not materially adversely affect the appraised value
     of the property as set forth in such appraisal;

          (iv)  other matters to which like properties are commonly subject and
     which do not materially interfere with the benefits of the security
     intended to be provided by the Mortgage Loan or the use, enjoyment, value
     or marketability of the related property,

          (v)  liens subordinate in priority to the lien in favor of the Seller;
     and


          (vi)  in the case of second priority Mortgage Loans, one lien superior
     in priority to the lien in favor of the Seller.

     (k)  The property shall be improved, and such improvements shall consist of
a completed one-to four-unit single family residence, including, but not limited
to, a condominium, planned unit development, townhouse, manufactured housing
which is permanently affixed to the underlying real estate, but excluding in any
event a co-op or mobile home.

     (l)  The Mortgage Loan is not subject to any servicing arrangement other
than the  Servicing Agreements nor are any servicing rights relating to the
Mortgage Loan subject to any lien, claim, interest or negative pledge in favor
of any Person other than as permitted hereunder.

                                       26

     (m)  The Additional Required Documents for each Mortgage Loan include an
appraisal of the property signed prior to the approval of the application for
such Mortgage Loan by a qualified appraiser, duly appointed by the originator of
the Mortgage Loan who has no interest, direct or indirect, in the mortgage
property or in any loan made on the security thereof, other than as an employee
of the originator and whose compensation is not affected by the approval or
disapproval of the Mortgage Loan.  The appraisal and appraiser both satisfy the
requirements of Title XI of the Federal Institutions Reform, Recovery, and
Enforcement Act of 1989 and the relegation's promulgated thereunder, all as in
effect on the date the Mortgage Loan was originated.

     (n)  The Mortgage Loan is secured by a first or second priority mortgage or

trust.

Agreement shall have been originated more than sixty (60) days prior to the date

Mortgage Loan in the appraisal referred to in (m) above; and provided further
that no Mortgage Loan secured by a second priority lien shall, when combined
with all mortgage loans secured by liens on the related property, have a
combined loan-to-value ratio of more than one hundred percent (100%).


     (s) The Mortgage Loan was originated by Seller in accordance with the
Underwriting Standards of Seller or, if such Mortgage Loan was acquired by
Seller, it was acquired from an Acceptable Originating Counterparty in
accordance with the Underwriting Standards pursuant to and in accordance with
the terms and conditions of an Underlying Agreement and is serviced by

     case may be, an amount equal to (A) Buyer's actual cost (including all
     fees, expenses and commissions) of (i) entering into replacement
     transactions; and (ii) entering into or terminating hedge transactions, (B)
     to 

                                       8

     substitution or termination and (C) in the case of the termination of any

     loan, contemporaneously with the grant of the security interest in the
     Collateral by Seller to Buyer pursuant to Paragraph 6 hereof and the

     an amount equal to the price therefor on such date, obtained from a
     generally recognized source or the most recent closing bid quotation from
     such a source, against the aggregate unpaid Repurchase Prices and any other
     amounts owing by the defaulting party hereunder and in either case upon the
     receipt and crediting by Buyer, in a manner deemed final and complete by
     Buyer in its sole and absolute discretion, of the aggregate unpaid
     Repurchase Prices and any other amounts owing by the defaulting party,
     including, without limitation, (x) any unpaid fees and expenses, (y)

the payment of fees or other sums due and owing to Seller in its capacity as
Servicer) and, to the extent permitted under any Servicing Agreement, terminate
any Servicing Agreements without any liability to the applicable Servicer
(including, without limitation,

without liability for the payment of fees or other sums due to owing to such
Servicer) and (ii) transfer servicing responsibility for any Mortgage Assets to
any third party servicer Buyer selects.

          (k) The parties hereto recognize that Seller's obligations to Buyer
under this Master Repurchase Agreement are special, unique and of extraordinary
character.  If an Event of Default occurs hereunder, Seller agrees that Buyer
may enforce this Master Repurchase Agreement by a proceeding for specific
performance or other equitable remedy including, without limitation, a
proceeding in which replevin or injunction is sought by Buyer.  Seller hereby
waives to the fullest extent permitted by law any and all rights it may have by
statute, constitution or otherwise, to (a) assert the defense of adequacy of a
remedy at law that might be asserted as a bar to any such proceeding, (b) the
fixing, imposition or posting of a bond or other security by Buyer as a
condition to obtaining any equitable relief sought by Buyer.  Seller further
agrees that the rights and remedies hereunder are cumulative, and are not
exclusive of any rights, powers, privileges, or remedies, now or hereafter

          (ii)     Seller has no actual knowledge of any pending or threatened
                   litigation or any basis therefor against Seller or any
                   Guarantor before any court, governmental agency or authority
                   or arbitration panel, which, if determined adversely to
                   Seller or such Guarantor, would have a materially adverse
                   effect on Seller's or such Guarantor's ability to perform
                   its obligations under the Related Documents or the guaranty

                   condition or results of operations.

          (v)      The information set forth in the schedule to each
                   Confirmation is true and correct in all material respects.

Purchase Date and until this Master Repurchase Agreement is no longer in force
with respect to any Transaction, Seller covenants that:

          (a) it will not take any action which would directly or indirectly

                    in default under the terms and conditions of this Master
                    Repurchase Agreement or under any agreement evidencing or

     breach of, or constitute a default under, or require any consent under, any
     contractual obligation to which the Company is a party or by which the
     Company is bound or affected. The Company has taken sufficient corporate
     action to reserve a sufficient number of shares of authorized but unissued
     Common Stock in connection with the prospective issuance of the Warrant
     Shares.

             (iii)  This Warrant Agreement has been duly executed and delivered
     by the Company and constitutes a legal, valid, binding and enforceable
     obligation of the Company, except as limited by bankruptcy, insolvency or
     other similar laws now or hereafter in effect affecting the enforcement of
     creditors' rights and by the application of equitable principles. The
     Warrants and the Warrant Certificates constitute legal, valid, binding and
     enforceable obligations of the Company, except as limited by bankruptcy,
     insolvency or other similar laws now or hereafter in effect affecting the
     enforcement of creditors' rights and by the application of equitable
     principles, and the Warrant Shares, 

                                       5
<PAGE>
 
     when issued upon exercise of the Warrants, will be duly authorized, validly
     issued, fully paid and nonassessable and be free from all taxes, liens and
     charges with respect to the issuance thereof (other than any liens or
     charges resulting from the Holder's actions).

             (iv)   The Company's authorized shares of Common Stock are as
     described in the Company's Charter. A total of 8,130,069 shares of Common
     Stock were issued and outstanding on February __, 1999.

             (v)    Except as set forth on Exhibit E, there are no Options,
     subscriptions or similar rights to acquire from the Company, or agreements
     or other obligations by the Company, absolute or contingent, to issue, sell
     or register shares of Common Stock, whether by Public Offering or on
     conversion or exchange of Convertible Securities or otherwise.

             (vi)   No holder of shares of Common Stock of the Company has any
     preemptive rights to subscribe for or to purchase any Warrants or Warrant
     Shares under the Company's Charter, any agreement to which the Company is a
     party or otherwise bound or the corporation law of the Company's
     jurisdiction of organization.

             (vii)  Assuming the accuracy of First Union's representations as
     set forth in Section 2(c), no consent, approval, authorization or other
     order of any court, regulatory body, administrative agency or other
     governmental body is required to be obtained by the Company in connection
     with the execution of this Warrant Agreement and the transactions
     contemplated hereby, including the valid issuance of the Subject
     Securities.

             (viii) Assuming the accuracy of First Union's representations as
     set forth in Section 2(c), it is not necessary in connection with the
     offer, issuance or sale to First Union of the Subject Securities to
     register the Subject Securities under the Act or any Blue Sky Law. The
     Company will not take or authorize any action which may cause the issuance
     or sale of the Subject Securities to be subject to any such registration,
     except as contemplated by Section 12.

             (ix)   No legal proceeding or investigation is pending or to the
     best knowledge of the Company threatened before any court, arbitrator or
     administrative or governmental authority, bureau or agency to restrain or
     prohibit the Company from performing this Warrant Agreement or the
     transactions contemplated hereby.

             (x)    No representation or warranty made by the Company in this
     Warrant Agreement, or in any schedule, written statement or certificate
     furnished to the Holder in connection with the transactions contemplated by
     this Warrant Agreement, contains any untrue statement of a material fact or
     omits to state a material fact necessary to make the statements contained
     herein and therein not false or misleading.

     (b)     The Company hereby covenants for so long as this Warrant Agreement
remains in effect that:

             (i)  The Company will not (and will cause any Affiliate not to)
     take any 

                                       6
<PAGE>
 
     action, including, without limitation, amending the Company's Charter,
     reorganizing, consolidating, merging, dissolving, transferring assets or
     issuing or selling securities or take any other voluntary action, to avoid,
     or seek to avoid, observing or performing any of the terms, or complying
     with the essential intent and principles, of this Warrant Agreement or the
     Subject Securities, and will at all times in good faith assist in the
     carrying out of all such terms and in the taking of all such actions as may
     be necessary or appropriate to protect the rights of the Holders against
     dilution or impairment to the extent contemplated by the terms hereof. In
     furtherance and not in limitation of the foregoing, the Company shall not
     (1) enter into any agreement with respect to its securities that is
     inconsistent with the rights granted to Holders of Subject Securities in
     this Warrant Agreement or otherwise conflicts with the provisions hereof or
     (2) increase the par value of any Warrant Shares or other Securities above
     the Exercise Price then in effect. Before taking any action that would
     cause an adjustment pursuant to Section 14, the Company will take all
     corporate action that, in the opinion of its counsel (which may be counsel
     employed by the Company), may be necessary in order that the Company may
     validly and legally issue fully paid and nonassessable Warrant Shares at
     the then applicable Exercise Price.

             (ii)   The Company will take all actions necessary or appropriate
     to be taken by it to validly and legally issue fully paid and nonassessable
     shares of Common Stock upon exercise of the Warrants and will use best
     efforts to obtain all such authorizations, exemptions or consents from any
     public regulatory body having jurisdiction thereof as may be necessary to
     enable the Company to perform its obligations under this Warrant Agreement.
     In respect of the issuance of the Warrants to the Holders, the exercise
     thereof by the Holders and the resulting issuance of Subject Securities,
     the Company shall not set off, recoup, claim, abate, withhold or defer any
     property or amount for any reason whatsoever.

             (iii)  At all times during the term of this Warrant Agreement, the
     Company shall retain a nationally recognized accounting firm as its
     auditor.

             (iv)   (A) The Company will file with the Commission such
     information as the Commission may require under Section 13 or 15(d) of the
     Exchange Act, as applicable, and shall use its best efforts to take all
     action as may be required as a condition to the availability of Rule 144 or
     Rule 144A under the Act (or any successor or similar exemptive rules
     hereafter in effect) and (B) the Company shall (1) furnish to any Holder of
     Subject Securities upon request a written statement executed by the Company
     as to the steps it has taken to comply with the current public information
     requirements of Rule 144 or Rule 144A or such successor rules and (2) make
     available to Holders of Subject Securities such reports, documents and
     information as such Holders reasonably request to enable such Holders to
     make sales of Subject Securities pursuant to such rules. If the Company
     ceases to be subject to Section 13 or 15(d) of the Exchange Act, the
     Company shall make available to the Holder of Subject Securities in
     connection with any sale thereof, the information required by Rule
     144A(d)(4) under the Act in order to permit resales of Subject Securities
     pursuant to Rule 144A.

             (v)  If the Company becomes eligible to use Form S-3 under the Act
     or a 

                                       7
<PAGE>
 
     comparable successor form, the Company shall use its best efforts to
     continue to qualify at all times for registration of its shares of Common
     Stock on Form S-3 or such successor form.

             (vi)   In the event that any of the terms of the warrant agreement
     or the warrants to be issued by the Company to GMAC/Residential Funding
     Corporation or any of its Affiliates (collectively, "GMAC"), other than (1)
     the initial exercise price, (2) the term of the warrant agreement, (3) the
     grant of tag-along rights to GMAC, and (4) the number of warrants to be
     issued, are more favorable to GMAC than the terms hereof are to the
     Holders, then a majority in interest of the Holders may prepare, and the
     Company agrees to sign, an amendment to this Warrant Agreement making such
     changes as shall be necessary in order to make the terms of this Warrant
     Agreement at least as favorable as those set forth in the Warrant Agreement
     or warrants to be issued to GMAC ("GMAC Warrants").

             (vii)  In the event that the Company reduces the exercise price of
     the 1996 Warrants to an amount below the Exercise Price of the Warrants,
     the Exercise Price of the Warrants shall be reduced concurrently to such
     lower price.

     (c) First Union hereby represents and warrants to and agrees with the
Company that:

             (i)    First Union is acquiring and will acquire the Subject
     Securities for its own account for investment and not with a view to any
     distribution thereof that might cause a violation of the Act or any rules
     or regulations thereunder; provided, however that subject to Section 6
     hereof, the disposition of the Subject Securities shall be at all times
     within the sole discretion of the Holders.

             (ii)   First Union has had an opportunity to ask questions of the
     principal officers and representatives of the Company and to obtain any
     additional information necessary to permit an evaluation of the benefits
     and risks associated with the investment made hereby.

             (iii)  First Union has had sufficient experience in business,
     financial and investment matters to evaluate the merits and risks involved
     in the investment made hereby and is able to bear the economic risk of such
     investment for an indefinite period of time.

     (d)     In addition to any reduction in the Exercise Price required by
     Sections 2(b)(vii) and 14, the Company and First Union hereby agree that
     the Company shall have the right to reduce the Exercise Price at any time,
     in its sole discretion, for such limited periods as it may from time to
     time determine, upon no less than 10 days and no more than 60 days prior
     written notice to Holders, provided that no such reduction may be effected
     without the approval of a majority of Company's Board of Directors.

     Section 3.  Warrant Certificates.  The Warrant Certificates shall be in
              --------------------                                         
registered form only and shall be substantially in the form of Exhibit B hereto,
                                                               ---------        
with such changes therein as may be required from time to time to reflect any
adjustments made pursuant to Section 14 hereof.  

                                       8
<PAGE>
 
The Warrant Certificates may have such letters, numbers or other marks of
identification or designation and such legends, summaries or endorsements
printed, lithographed or engraved thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this Warrant Agreement, or as
may be required to comply with any law, or with any rule or regulation made
pursuant thereto, or with any rule or regulation of any stock exchange on which
the Common Stock or the Warrants may be listed, or any inter-dealer quotation
system upon which the Common Stock or the Warrants may be quoted. Warrant
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, President or any Executive or Senior Vice President, and attested by its
Secretary or an Assistant Secretary. The signature of any of such officers may
be manual or facsimile. Warrant Certificates bearing the manual or facsimile
signatures of individuals who were at any time the proper officers of the
Company shall bind the Company, notwithstanding that any of such individuals
shall have ceased to hold such offices prior to the delivery of such Warrant
Certificates or did not hold such offices on the date of this Warrant Agreement.

  Section 4.  Issuance and Delivery of Warrant Certificates.  The Company
              ---------------------------------------------                
hereby agrees to issue and deliver on the Closing Date to First Union 350,000
Warrants registered in the name of First Union, and shall deliver to First Union
two (2) separate Warrant Certificates in the amount of 230,000 Warrants and
120,000 Warrants, evidencing such Warrants.  First Union hereby agrees to
deliver on the Closing Date to the Company for cancellation certificates
representing 186,667 1996 Warrants.

  Section 5.  Registration.  The Warrants shall be registered in the name(s)
              ------------                                                    
of the recordholder(s) thereof from time to time. The Company may deem and treat
the registered Holder(s) of the Warrants as the absolute owner(s) thereof
(notwithstanding any notation of ownership or other writing on the Warrant
Certificates made by anyone) for the purpose of any exercise thereof or any
distribution to the Holder(s) thereof, and for all other purposes.

  Section 6.  Transfer; Registration of Transfers and Exchanges.
              -------------------------------------------------   

  (a)  Subject to compliance with U.S. securities laws, the Warrants and all
rights thereunder are fully transferable in whole or in part and from time to
time to any Person. The Company shall register the transfer of any outstanding
Warrants made in accordance with the terms hereof and applicable law upon the
Register, upon surrender of the Warrant Certificate(s) to the Company's
principal office, accompanied by a written instrument of transfer substantially
in the form attached as Exhibit D, duly executed by the registered Holder(s)
thereof or by the duly appointed legal representative thereof. Upon any such
registration of transfer, new Warrant Certificate(s) evidencing such transferred
Warrants shall be issued to the transferee(s) and the surrendered Warrant
Certificate(s) shall be cancelled.

  (b)  Warrant Certificates may be exchanged at the option of the Holder
thereof, when surrendered to the Company at its principal office, for other
Warrant Certificates of like tenor

                                       9
<PAGE>
 
and representing in the aggregate a like number of Warrants. Warrant
Certificates surrendered for exchange shall be cancelled.

  Section 7.  Duration and Exercise of Warrants.
              ---------------------------------   

  (a)  The Warrants shall be exercisable by the Holder thereof on any Business
Day on or after the Closing Date and prior to the close of business on the
Expiration Date.

  (b)  Subject to the provisions of this Warrant Agreement, the Holder of each
Warrant shall have the right to purchase from the Company (and the Company shall
issue and sell to such Holder of a Warrant) one fully paid and nonassessable
share of Common Stock per Warrant held upon (i) surrender of the Warrant
Certificate evidencing such Warrant, with a purchase form substantially in the
form attached as Exhibit C duly filled in and signed, to the Company at its
principal office or at such other address as the Company may specify in writing
to the then registered Holders, and (ii) payment of the Exercise Price. Payment
of the Warrant Price shall be made at the option of the Holder by (i) cash or
certified or official bank check, (ii) by surrendering additional Warrants or
shares of Common Stock for cancellation to the extent the Company may lawfully
accept shares of Common Stock, with the value of such shares of Common Stock for
such purpose to equal the average Current Market Price of the Common Stock
during the 10 Trading Days immediately preceding the date of surrender and the
value of the Warrants to equal the difference between the aggregate value of the
Warrant Shares issuable on the exercise of such Warrants, calculated as set
forth in this clause 7(b)(ii), and the Exercise Price, or (iii) any combination
thereof, duly endorsed by or accompanied by appropriate instruments of transfer
duly executed by Holder or by Holder's attorney duly authorized in writing.

  (c)  Upon such surrender of the Warrant Certificate evidencing any Warrants
and payment of the Exercise Price, the Company shall, as promptly as
practicable, and in any event within five Business Days thereafter, issue and
cause to be delivered to, or upon the written order of, the Holder of such
Warrants and in such name or names as such Holder may designate, a certificate
for the Warrant Shares issued upon such exercise of such Warrants. Any Person(s)
so designated to be named therein shall be deemed to have become the Holder of
record of the Warrant Shares as of the Date of Exercise of such Warrants. The
stock certificate or certificates so delivered shall be, to the extent possible,
in such denomination or denominations as such Holder shall request.

  (d)  The Warrants evidenced by a Warrant Certificate are exercisable, from
time to time, either in whole or in part for any number of Warrant Shares as are
evidenced by the Warrant Certificate. If fewer than all of the Warrants
evidenced by a Warrant Certificate are exercised at any time, a new Warrant
Certificate or Certificates shall be issued as promptly as practicable (and in
any event within five Business Days), at the Company's expense, for the
remaining number of Warrants evidenced by such Warrant Certificate. All Warrant
Certificates surrendered upon exercise of Warrants shall be cancelled.

  Section 8.  Payment of Expenses and Taxes.  The Company shall pay all
              -----------------------------                              
expenses in connection with, and all taxes and other governmental charges that
may be imposed with respect to, the issue or delivery of Warrant Shares, unless
such tax or charge is imposed by law upon the 

                                       10
<PAGE>
 
Holder, in which case such taxes or charges shall be paid by the Holder. The
Company shall not be required, however, to pay any tax or other charge imposed
in connection with any transfer involved in the issue of any certificate for
Warrant Shares in any name other than that of the Holder.

  Section 9.  Mutilated or Missing Warrant Certificates  .  Upon receipt by the
              -----------------------------------------                        
Company from any Holder of evidence reasonably satisfactory to it of the loss,
theft, destruction or mutilation of a Warrant Certificate and indemnity
reasonably satisfactory to it (it being understood that the written agreement of
First Union, without posting of a bond, shall be sufficient indemnity), and in
case of mutilation upon surrender and cancellation of the mutilated Warrant
Certificate, the Company will execute and deliver in lieu thereof a new Warrant
Certificate of like tenor to such Holder; provided, in the case of mutilation,
                                          --------                            
no indemnity shall be required if the mutilated Warrant Certificate in
identifiable form is surrendered to Company for cancellation.

  Section 10.  Reservation and Issuance of Warrant Shares  .  The Company will
               ------------------------------------------                     
at all times authorize, reserve and have available, free from preemptive rights,
solely for the purpose of enabling it to satisfy any obligation to issue and
deliver Warrant Shares upon the exercise of the Warrants, the number of shares
of Common Stock that is equal to the total number of Warrant Shares issuable
upon the exercise of the Warrants, as such number shall vary from time to time
in accordance with Section 14, and, if necessary, will amend its Certificate of
Incorporation to provide sufficient reserves of shares of Common Stock issuable
upon exercise of the Warrants.  The transfer agent for the Common Stock and
every subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of the Warrants shall be irrevocably authorized and
directed at all times to reserve the maximum number of authorized shares as
shall be required for such purpose.  The Company shall keep a copy of this
Warrant Agreement on file with the transfer agent for the Common Stock and with
every subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of the Warrants.

  Section 11.  No Registration under the Act; Legend  .  None of the Subject
               -------------------------------------                        
Securities has been registered under the Act. In agreeing to issue the Warrants,
the Company has relied upon the exemption from registration provided by Section
4(2) of the Act on the ground that Warrants are to be issued in transactions by
an issuer not involving any Public Offering.

  A copy of this Warrant Agreement shall be filed with the Secretary of the
Company and kept at its principal office.  The Warrant Certificates shall
contain a legend substantially in the following form:

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

     (a)  Piggyback Registration
          ----------------------

          (i) If (and on each occasion that) the Company proposes to register
     any of its securities under the Act in connection with a Public Offering or
     effect an underwritten Public Offering under an effective shelf
     registration statement, either for the Company's own account and/or for the
     account of any of its securityholders, other than any such registration
     described in the next to last sentence of clause (ii) below (each such
     registration being herein called a Piggyback Registration), then the
     Company will give written notice to all Holders who then hold Registrable
     Securities (as hereinafter defined) of the Company's intention to effect
     such Piggyback Registration not later than the earlier to occur of (A) 30
     days prior to the anticipated initial filing date of such Piggyback
     Registration if such registration is on Form S-3 and (B) 45 days prior to
     such date if the registration is on any other form.

                                       13
<PAGE>
 
          (ii) Subject to the provisions contained in Section 12(b) and in the
     next to last sentence of this clause (ii), in connection with any
     registration subject to the provisions of this Section 12, if within 20
     days after the date of the Company notice pursuant to clause (i) above
     Holders of Registrable Securities request the inclusion of some or all of
     the Registrable Securities owned by them in such registration (in the form
     of shares of Common Stock to be obtained upon exercise of the Warrants then
     held by them), the Company will use best efforts to effect the registration
     under the Act of all Registrable Securities which such Holders request to
     be registered. Holders of Registrable Securities shall be permitted to
     withdraw all or any part of the Registrable Securities of such Holders from
     any Piggyback Registration at any time prior to the final filing (which has
     been made by and in the discretion of the Company) of such Piggyback
     Registration, and the Company shall have the right to postpone or withdraw
     any registration without obligation to any Holder (other than for payment
     of any reasonable expense incurred by the Holders). Notwithstanding
     anything herein to the contrary, the Company will not be obligated or
     required to include any Registrable Securities in any registration effected
     on Form S-4; on Form S-8 solely to implement an employee benefit plan
     (including any option plan) or a transaction of the type to which Rule 145
     of the Commission or any successor provision is applicable; or in
     connection with a dividend reinvestment or direct stock purchase plan for
     the benefit of the Company's stockholders. The term "Registrable
                                                          -----------
     Securities" shall mean the Warrants, any shares of Common Stock or Other
     ----------                                                              
     Securities issuable or issued upon exercise of the Warrants, any shares of
     Common Stock or Other Securities of the Company issued as a dividend or
     other distribution with respect to, or in exchange or in replacement of
     such shares of Common Stock.

     (b) Allocation on Piggyback Registrations.  In connection with an 
         -------------------------------------    
underwritten Public Offering, if the managing underwriter or underwriters in
connection with a Piggyback Registration shall advise the Company in writing
that, in the reasonable opinion of such managing underwriter or underwriters,
the inclusion of all Registrable Securities for which registration is requested
pursuant to Section 12(a) hereof would materially and adversely affect the
success of such offering, then subject to the rights, if any, of the Five
Percent Purchasers, registration for the Registrable Securities shall be cut
back such that (i) no Holder of Registrable Securities shall be entitled to
participate in such underwritten Public Offering unless all shares of Common
Stock proposed to be sold by the Company for its own account or for the account
of the parties for which the underwritten Public Offering was commenced as a
result of the exercise of demand registration rights ("Demanding Parties") have
been included in such underwritten Public Offering, and (ii) after the Company
or the Demanding Party has included its own shares of Common Stock, the Holders,
the holders of 1996 Warrants and the holders of GMAC Warrants (if not a
Demanding Party) and any other owners of Other Registrable Securities shall be
entitled to include their Registrable Securities and Other Registrable
Securities in an amount up to the amount that such managing underwriter or
underwriters advise may be included therein (as allocated among the Holders, the
holders of 1996 Warrants, the holders of GMAC Warrants and such other owners of
Registrable Securities pro rata on the basis of the number of securities
requested to be included therein by each such Holder or holder).

     (c)     Demand Registration.
         ------------------- 

         (i) The Company shall cause to be filed with the Commission as promptly
     as practicable, but in no event more than three (3) months following the
     Closing Date, a shelf Registration Statement pursuant to Rule 415 under the
     Securities Act (the "Shelf Registration Statement") on Form S-11 (or other
     appropriate form, such as Form S-3 after having established eligibility
     therefor) to cover sales of the Registrable Securities. In connection with
     the Shelf Registration Statement, the Company shall also register the offer
     and sale of the Warrant Shares issuable upon exercise of the Warrants as a
     primary registration. The Company shall use its best efforts to cause such
     Shelf Registration Statement to be declared effective by the Commission as
     soon as practicable thereafter. The Company shall use its best efforts to
     keep such Shelf Registration Statement continuously effective until the
     earlier to occur of three (3) years following the Closing Date or such time
     as, in the written opinion of counsel to the Company, such registration is
     not required for the unrestricted resale under Rule 144 (k) of Registrable
     Securities entitled to registration rights under this Agreement. If Holders
     of a majority of the Registrable Securities to be registered for resale in
     the Shelf Registration Statement so elect, an offering of Registrable
     Securities pursuant to the Shelf Registration Statement may be effected in
     the form of an underwritten offering. Upon the receipt of a notice of
     election by a majority of the Registrable Securities to effect an
     underwritten offering, the Company will notify in writing all Holders whose
     names are not included in such notice and such non-electing Holders may,
     within five (5) business days of receipt of such notice, elect to be
     included with, and treated as, an electing Holder. If the managing
     underwriter or underwriters advises the Company and the Holders of such
     Registrable Securities that in its opinion the amount of Registrable
     Securities proposed to be sold in such offering exceeds the amount of
     Registrable Securities which can be sold in such offering, there shall be
     included in such underwritten offering the amount of such Registrable
     Securities which in the opinion of such underwriter(s) can be sold, and
     such amount or number of shares of such Registrable Securities shall be
     allocated pro rata among the Holders electing to participate in such
     underwritten offering.

         (ii) In addition to their rights under Sections 12(a), (b) and (c)(i)
     hereof following the expiration of the Shelf Registration Statement,
     Holders collectively holding at least 25% of the then outstanding
     Registrable Securities shall have the right to request and have effected
     registrations of Registrable Securities for a Public Offering of
     Registrable Securities unless, in the written opinion of counsel to the
     Company, which opinion is reasonably acceptable to such Holders, such
     registration is not necessary for such Holders to sell their Registrable
     Securities in the manner contemplated in compliance with applicable
     securities laws. Such requests shall be in writing and shall state the
     number of Registrable Securities to be disposed of and the intended method
     of disposition of such Registrable Securities by such Holders. The Company
     shall give notice to all of the Holders of Registrable Securities of the
     receipt of a request for registration pursuant to this Section 12(c)(ii)
     and shall provide a reasonable opportunity for such Persons to participate
     in such a registration provided they elect to do so in writing to the
     Company within 15 days after the date of the Company's notice. Subject to
     the foregoing, the Company will use its best efforts to effect promptly the
     registration of all Registrable Securities to the extent requested by the
     Holder or Holders thereof, and to 

                                       15
<PAGE>
 
     keep such registration effective for 36 months or until all such Holder's
     Registrable Securities registered thereunder are sold, whichever is
     shorter. If so requested by any Holder in connection with a registration
     under this Section 12(c)(ii), and if the Company is then eligible to use
     Form S-11 or Form S-3, the Company shall take such steps as are required to
     register such Holder's Registrable Securities for sale on a delayed or
     continuous basis (the "Supplemental Shelf Registration") under Rule 415 of
     the Act or any successor provision (if applicable).

          (iii)  The Company further agrees to use its best efforts to prevent
     the happening of any event that would cause a Registration Statement to
     contain a material misstatement or omission or to be not effective and
     usable for resale of the Registrable Securities during the period that such
     Registration Statement is required to be effective and usable.  Upon the
     occurrence of any event that would cause a Registration Statement (1) to
     contain a material misstatement or omission, or (2) to be not effective and
     usable for resale of Registrable Securities during the period that such
     Registration Statement is required to be effective and usable, the Company
     shall as promptly as reasonably practicable file an amendment to the
     Registration Statement, in the case of clause (1) immediately above,
     correcting any such misstatement or omission, and in the case of either
     clause (1) or (2) immediately above, use its best efforts to cause such
     amendment to be declared effective and such Registration Statement to
     become usable as soon as reasonably practicable thereafter.  If requested
     by the majority in interest of the Holders selling Registrable Securities
     pursuant to an underwritten offering as provided in this Section 12(c), the
     Company's management shall cooperate in roadshow presentations to assist
     such Holders in selling their Registrable Securities and shall otherwise
     work in good faith with any managing underwriter(s) in connection with
     taking all actions necessary to successfully consummate the Public
     Offering.  If any demand registration pursuant to this Section 12(c)
     involves an underwritten public offering, the underwriter(s) to be used in
     connection with such registration shall be selected by a majority in
     interest of the Holders of Registrable Securities to be sold in such
     registration , subject to the approval of the Company (which shall not be
     unreasonably withheld).

          (iv)   Notwithstanding Sections 12(c)(i) and (ii) above, if the
     Company files a Registration Statement (other than on Form S-4 or Form S-8
     or any successor form or in connection with a dividend reinvestment plan or
     direct stock purchase plan) with respect to an underwritten Public Offering
     of Common Stock or proposes to effect an underwritten Public Offering for
     its own account or the account of a Demanding Party pursuant to an
     effective shelf registration statement and the managing underwriter or
     underwriters advise the Company in writing that an underwritten offering of
     Registrable Shares would materially and adversely affect the success of
     such proposed underwritten Public Offering, then the Company shall provide
     timely written notice of such advice from the underwriter(s) to the Holders
     (a "Holdback Notice") and the Company shall not be required (1) to cause a
     Registration Statement for an underwritten Public Offering that is demanded
     pursuant to Section 12 (c)(ii) after the date on which the Holdback Notice
     is given to the Holders to become effective or (2) to effect an
     underwritten Public Offering under a Shelf Registration Statement that is
     elected pursuant to Section 12(c)(i) after the date on which such Holdback
     Notice is given, in either case until the earlier of (A) the abandonment of
     the previously proposed underwritten offering or (B) 90 days after the

                                       16
<PAGE>
 
     effective date of the registration statement for such previously proposed
     Public Offering or, in the case of a previously proposed Public Offering
     pursuant to an effective shelf registration statement, 75 days after the
     first day on which sales to the public commence pursuant to such offering,
     in either case unless a shorter period is agreed to by such managing
     underwriter or underwriters (the "Delay Period"); provided that the Company
     shall use its best efforts (taking into account the possibility of other
     pending demands for registration made by other securityholders) to effect
     an underwritten Public Offering under a Shelf Registration Statement
     elected under Section 12(c)(i) or to achieve the effectiveness of the
     Registration Statement demanded pursuant to Section 12 (c) (ii), as the
     case may be, promptly following such Delay Period and that the Company
     shall treat any demand or election by the Holders with at least the same
     priority as any pending demands for registration made by other
     securityholders. The foregoing provisions shall not apply to a previously
     proposed underwritten Public Offering for the account of a Demanding Party
     unless such Demanding Party has agreed to restrictions on such Demanding
     Party's ability to sell securities of the Company after the Holders demand
     or elect, as the case may be, an underwritten Public Offering (which
     restrictions shall be at least as favorable to the Holders as those
     provided to other Demanding Parties under this Section 12(c)(iv)). This
     Section 12(b)(iv) shall not apply to any Holder of Registrable Securities
     if such Holder is prevented by applicable statute or regulation from
     entering into any such agreement; provided, however, that any such Holder
     shall undertake upon written request not to effect any underwritten
     offering during the Delay Period unless it has provided forty-five (45)
     days' prior written notice of such offering to the managing underwriter or
     underwriters.

          (v) The Company agrees that without the written consent of the
     managing underwriter or underwriters in an underwritten offering of
     Registrable Securities pursuant to Sections 12(a) and 12(c) hereof, it will
     not effect any public sale or distribution of its equity securities (except
     (i) pursuant to registrations on Form S-4 or Form S-8 or any successor form
     or pursuant to any dividend reinvestment or direct stock purchase plan of
     the Company, (ii) in connection with an exchange offer, or (iii) in
     connection with the acquisition of assets by the Company or its
     subsidiaries) from the date the Company receives a notice of election to
     effect an underwritten offering under Section 12(c) (i) or a demand for
     registration under Section 12(c) (ii) until the earlier of (A) the
     abandonment of such underwritten offering or (B) 90 days after the
     effective date of the registration statement for such previously proposed
     Public Offering or, in the case of a previously proposed Public Offering
     pursuant to an effective Shelf Registration Statement, 75 days after the
     first day on which sales to the public commence pursuant to such offering,
     in either case unless a shorter time period is agreed upon by the managing
     underwriter or underwriters.

  (d)   Other Provisions Relating to Registration Rights.  In connection with 
        ------------------------------------------------         
the Company's registration obligations pursuant to this Section 12, the Company
shall as expeditiously as possible:

        (i) Prepare and file with the Commission, as soon as practicable, a
  Registration Statement or Registration Statements on such form as shall be
  available for the sale of the Registrable Securities by the Holders thereof in
  accordance with the 

                                       17
<PAGE>
 
     intended method or methods of distribution thereof, and use its best
     efforts to cause such Registration Statement to become effective and to
     remain effective as provided herein; provided, however, that before filing
     a Registration Statement or Prospectus or any amendments or supplements
     thereto (including documents that would be incorporated or deemed to be
     incorporated therein by reference), the Company shall notify the Holders of
     the Registrable Securities covered by such Registration Statement, their
     counsel and the managing underwriters, if any, of its intention to file
     such documents, and upon written request shall furnish to such parties so
     requesting copies of all such documents proposed to be filed, which
     documents will be subject to the review of such Holders, their counsel and
     such underwriters, if any; provided, further, that the Company shall not be
     required to deliver to such Holders a copy of any such document that has
     not been materially changed from a copy of such document that was
     previously delivered to such Holders.

          (ii)   Prepare and file with the Commission such amendments and post-
     effective amendments to each Registration Statement as may be necessary to
     keep such Registration Statement continuously effective during the period
     provided in this Warrant Agreement with respect to the disposition of all
     securities covered by such Registration Statement, and cause the related
     Prospectus to be supplemented by any required Prospectus supplement, and as
     so supplemented to be filed pursuant to Rule 424 (or any similar provisions
     then in force) under the Act.

          (iii)  Notify the selling Holders of the Registrable Securities, their
     counsel and the managing underwriters, if any, promptly, and (if requested
     in writing by any such Person), confirm such notice in writing: (1) when a
     Registration Statement or any amendment thereto has been filed, and, with
     respect to a Registration Statement or any post-effective amendment, when
     the same has become effective, (2) of any request by the Commission or any
     other Federal or state governmental authority for amendments or supplements
     to a Registration Statement or related Prospectus or for additional
     information, (3) of the issuance by the Commission of any stop order
     suspending the effectiveness of a Registration Statement or the initiation
     of any proceedings for that purpose, (4) if at any time the representations
     and warranties of the Company contained in any agreement (including any
     underwriting agreement) contemplated by Section 12(d)(xiv) below cease to
     be true and correct, (5) of the receipt by the Company of any notification
     with respect to the suspension of the qualification or exemption from
     qualification of any of the Registrable Securities for sale in any
     jurisdiction, or the initiation or threatening of any proceeding for such
     purpose, and (6) of the happening of any event that makes any statement
     made in such Registration Statement or related Prospectus or any document
     incorporated or deemed to be incorporated therein by reference untrue in
     any material respect or that requires the making of any changes to such
     Registration Statement, Prospectus or documents so that, in the case of the
     Registration Statement, it 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, and
     that in the case of the Prospectus, it will not contain any untrue
     statement of a material fact or omit to state any material fact necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

                                       18
<PAGE>
 
          (iv)   Use its best efforts to obtain the withdrawal of any order
     suspending the effectiveness of a Registration Statement, or the lifting of
     any suspension of the qualification (or exemption from qualification) of
     any of the Registrable Securities for sale in any jurisdiction.

          (v)    If requested by the managing underwriters, if any, or the
     Holders of a majority in interest of the Registrable Securities being sold
     in connection with an underwritten offering, promptly include in a
     Prospectus supplement or post-effective amendment such information as the
     managing underwriters, if any, and such Holders may reasonably request in
     order to permit the intended method of distribution of such securities and
     make all required filings of such Prospectus supplement or such post-
     effective amendment as soon as practicable after the Company has received
     such request.

          (vi)   Furnish to each selling Holder of Registrable Securities, their
     counsel and each managing underwriter, if any, without charge, at least one
     conformed copy of the Registration Statement and each post-effective
     amendment thereto, including financial statements (including schedules, all
     documents incorporated or deemed to be incorporated therein by reference,
     and all exhibits).
 
          (vii)  Deliver to each selling Holder, their counsel, and the
     Underwriters, if any, without charge, as many copies of the Prospectus or
     Prospectuses (including each form of prospectus) and each amendment or
     supplement thereto as such Persons may reasonably request in connection
     with the distribution of the Registrable Securities; and the Company hereby
     consents to the use of such Prospectus and each amendment or supplement
     thereto by each of the selling Holders of Registrable Securities and the
     underwriters, if any, in connection with the offering and sale of the
     Registrable Securities covered by such Prospectus and any such amendment or
     supplement thereto.

          (viii) Use its best efforts to register or qualify, or obtain an
     exemption therefrom (or cooperate with the selling Holders of Registrable
     Securities, the underwriters, if any, and their respective counsel in
     connection with the registration or qualification (or exemption from such
     registration or qualification)) of such Registrable Securities for offer
     and sale under the securities or "Blue Sky" laws of such jurisdictions
     within the United States as any seller (or underwriter) reasonably requests
     in writing and to keep each such registration or qualification (or
     exemption therefrom) effective during the period such Registration
     Statement is required to be kept effective; provided, however, that the
     Company will not be required to (1) qualify generally to do business in any
     jurisdiction where it is not then so qualified, or (2) take any action that
     would subject it to general service of process or to taxation in any
     jurisdiction where it is not then so subject other than as to matters and
     transactions related to such Registration Statement.

          (ix)   Cooperate with the selling Holders of Registrable Securities
     and the managing underwriters, if any, to facilitate the timely preparation
     and delivery of certificates representing Registrable Securities to be
     sold, which certificates shall be in a form eligible for deposit with The
     Depository Trust Company; and enable such Registrable Securities to be in
     such denominations and registered in such names as the 

                                       19
<PAGE>
 
     managing underwriters, if any, or Holders may request in writing at least
     two (2) business days prior to any sale of Registrable Securities.

          (x)    Use its best efforts to cause the Registrable Securities
     covered by such Registration Statement to be registered with or approved by
     such other governmental agencies or authorities within the United States as
     may be necessary to enable the seller or sellers thereof or the
     underwriters, if any, to consummate the disposition of such Registrable
     Securities.

          (xi)   Upon the occurrence of any event contemplated by Section
     12(d)(iii)(6) above, prepare a supplement or post-effective amendment to
     the Registration Statement or a supplement to the related Prospectus or any
     document incorporated or deemed to be incorporated therein by reference, or
     file any other required document so that, as thereafter delivered to the
     purchasers of the Registrable Securities being sold thereunder, such
     Prospectus will not contain an untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading.

          (xii)   Prior to the effective date of the Registration Statement
     relating to the Registrable Securities, provide a CUSIP number for the
     Registrable Securities.

          (xiii)  Use its best efforts to cause the Common Stock covered by such
     Registration Statement to be listed on the New York Stock Exchange (or on
     such other exchange or trading system on which the Common Stock is then
     listed or authorized to be quoted), and to cause all Registrable Securities
     other than Common Stock that are covered by such Registration Statement to
     be authorized to be quoted on the NASDAQ/NMS or listed on a national
     securities exchange to the extent eligible therefor under the rules of the
     NASDAQ/NMS or such national securities exchange.

          (xiv)   Enter into such agreements (including an underwriting
     agreement in form, scope and substance as is customary in underwritten
     offerings) and take all such other actions reasonably requested by the
     Holders of a majority in interest of the Registrable Securities being sold
     in connection therewith (including those reasonably requested by the
     managing underwriters, if any) in order to expedite or facilitate the
     disposition of such Registrable Securities, and in such connection, whether
     or not an underwriting agreement is entered into and whether or not the
     registration is an underwritten offering, (1) make such representations and
     warranties to the Holders of such Registrable Securities and the
     underwriters, if any, with respect to the business of the Company and its
     subsidiaries, and the Registration Statement, Prospectus and documents, if
     any, incorporated or deemed to be incorporated by reference therein, in
     each case, in form, substance and scope as are customarily made by issuers
     to underwriters in underwritten offerings, and, if true, confirm the same
     if and when requested in writing to do so, (2) obtain opinions of counsel
     to the Company and updates thereof (which counsel and opinions, in form,
     scope and substance, shall be reasonably satisfactory to the managing
     underwriters, if any, and counsel to the Holders of Registrable Securities
     being sold), addressed to each selling Holder and each of the underwriters,
     if any, covering the matters customarily covered in opinions requested in
     underwritten offerings and such other matters as may be reasonably

                                       20
<PAGE>
 
     requested in writing by such counsel and underwriters, (3) obtain "cold
     comfort" letters and updates thereof from the independent certified public
     accountants of the Company (and, if necessary, any other independent
     certified public accountants of any subsidiary of the Company or of any
     business acquired by the Company for which financial statements and
     financial data are, or are required to be, included in the Registration
     Statement), addressed to each selling Holder (unless such accountants shall
     be prohibited from so addressing such letters by applicable standards of
     the accounting profession) and each of the underwriters, if any, such
     letters to be in customary form and covering matters of the type
     customarily covered in "cold comfort" letters in connection with
     underwritten offerings, (4) if an underwriting agreement is entered into,
     the same shall contain indemnification provisions and procedures
     substantially to the effect set forth in Section 12(f) hereof with respect
     to all parties to be indemnified pursuant to Section 12(f) and (5) deliver
     such additional documents and certificates as may be reasonably requested
     by the Holders of a majority of the Registrable Securities being sold,
     their counsel and the managing underwriters, if any, to evidence the
     continued validity of the representations and warranties made pursuant to
     Section 12(d)(xiv)(1) above and to evidence compliance with any customary
     conditions contained in the underwriting agreement or other agreement
     entered into by the Company. The above shall be done at each closing under
     such underwriting or similar agreement, or as and to the extent required
     thereunder.

           (xv)  Make available for inspection by a representative of the
     Holders of Registrable Securities being sold, each underwriter
     participating in any such disposition of Registrable Securities, if any,
     and any attorney or accountant retained by such selling Holder or
     underwriter, at the offices where normally kept, during reasonable business
     hours, all financial and other records, pertinent corporate documents and
     properties of the Company and its subsidiaries, and cause the officers,
     directors and employees of the Company and its subsidiaries to supply all
     information reasonably requested by any such representative, underwriter,
     attorney or accountant in connection with such Registration Statement;
     provided, however, that any information that is designated by the Company
     in writing as confidential at the time of delivery of such information
     shall be kept confidential by such Persons unless (1) disclosure of such
     information is required by court or administrative order, (2) disclosure of
     such information, in the opinion of counsel to such Person, is required by
     law, or (3) such information becomes generally available to the public
     other than as a result of a disclosure or failure to safeguard by such
     Person. Without limiting the foregoing, no such information shall be used
     by such Person as the basis for any market transactions in securities of
     the Company or its subsidiaries in violation of law.

           (xvi) Comply with all applicable rules and regulations of the
     Commission and make generally available to its security Holders earning
     statements satisfying the provisions of Section 11(a) of the Act and Rule
     158 thereunder, or any similar rule promulgated under the Act, no later
     than forty-five (45) days after the end of any twelve (12) month period (or
     ninety (90) days after the end of any twelve (12) month period if such
     period is a fiscal year) (A) commencing at the end of any fiscal quarter in
     which Registrable Securities are sold to underwriters in a firm commitment
     or best efforts underwritten offering, and (B) if not sold to underwriters
     in such an offering, commencing on the first day of the first fiscal
     quarter of the Company after the effective 

                                       21
<PAGE>
 
     date of a Registration Statement, which statements shall cover such twelve
     (12) month periods.

           (xvii)  Make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of any Registration Statement at the
     earliest possible moment.

           (xviii)  Cooperate and assist in any filings required to be made with
     the NASD and in the performance of any due diligence investigation by any
     underwriter (including any "qualified independent underwriter" that is
     required to be retained in accordance with the rules and regulations of the
     NASD).

     (e)  Registration Expenses.  All fees and expenses incident to the 
          ---------------------       
Company's performance of or compliance with this Section 12 will be borne by the
Company, regardless of whether a Registration Statement filed pursuant to this
Section 12 becomes effective and whether or not any securities are sold pursuant
to such Registration Statement, including without limitation:

          (i)   all registration and filing fees and expenses associated
     therewith including, without limitation, fees and expenses with respect to
     filings required to be made with the Commission and the NASD;

          (ii)  fees and expenses of compliance with federal securities or state

     of printing or engraving certificates for the Registrable Securities in a

          (iv)  reasonable fees and disbursements of counsel for the Company and
     of not more than one counsel for the Holders of Registrable Securities
     (chosen by a majority of the Holders of the Registrable Securities to be
     included in the Registration Statement);

          (v)   fees and disbursements of all independent certified public
     accountants of the Company (including the expenses of any special audit and
     "cold comfort" letters required by or incident to such performance);

          (vi)  fees and expenses associated with any NASD filing required to be
     made in connection with a Registration Statement, including, if applicable,
     the fees and expenses of any "qualified independent underwriter" (and its
     counsel) that is required to be retained in accordance with the rules and
     regulations of the NASD; and

          (vii) fees and expenses of listing the Registrable Securities on any
     securities exchange or quotation system in accordance with Section
     12(d)(xii) hereof.

                                       22
<PAGE>
 
     The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, rating
agency fees and the fees and expenses of any Person, including special experts,
retained by the Company. The Holders of Registrable Securities shall bear the
expense of any broker's commission or Underwriters' discount or commission.

     (f) Indemnification; Contribution.
         ----------------------------- 

         (i)  Subject to applicable law, the Company will indemnify and hold
     harmless each Holder of Registrable Securities (and each underwriter for
     such Holder (if any and if retained by the Holder)) being registered, and
     each person who controls any of them within the meaning of Section 15 of
     the Act or Section 20 of the Exchange Act, to the full extent lawful, from
     and against any and all losses, claims, damages, judgments, expenses and
     liabilities, joint or several (including any investigation, legal and other
     expenses incurred in connection with, and any amount paid in any settlement
     of, any action, suit or proceeding or any claim asserted), to which they,
     or any of them, may become subject under the Act, the Exchange Act or other
     federal or state statutory law or regulation, at common law or otherwise,
     insofar as such losses, claims, damages, judgments, expenses or liabilities
     arise out of or are based on (A) any untrue statement or alleged untrue
     statement of a material fact contained in such Registration Statement
     (including any related preliminary or definitive Prospectus, or any
     amendment or supplement to such Registration Statement or Prospectus), (B)
     any omission or alleged omission to state in such document a material fact
     required to be stated in it or necessary to make the statements in it not
     misleading, or (C) any violation by the Company of the Act, the Exchange
     Act, any Blue Sky Laws or any rule or regulation thereunder in connection
     with such registration; provided, however, that the Company will not be
     liable to the extent that such loss, claim, damage, judgment, expense or
     liability arises from and is based on a material untrue statement or
     omission or alleged material untrue statement or omission made in reliance
     on and in conformity with information furnished in writing to the Company
     by such Holder, underwriter or controlling person expressly for use in such
     Registration Statement. Each Holder of Registrable Securities will
     indemnify and hold harmless the Company, each other Holder of Registrable
     Securities and each person who controls any of them within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, from and against
     any and all losses, claims, damages, judgments, expenses and liabilities,
     joint or several, to which they, or any of them, may become subject under
     the Act, the Exchange Act or other federal or state statutory law or
     regulation, at common law or otherwise insofar as such losses, claims,
     damages, judgments, expenses and liabilities arise solely by reason of a
     material untrue statement or omission made in reliance on and in conformity
     with information furnished in writing to the Company by such Holder for use
     in such Registration Statement. The obligations of any Holder under this
     clause (i) shall be limited to the net proceeds to such Holder of the
     Registrable Securities sold pursuant to the Registration Statement to which
     the loss, claim, damage, judgment, expense or liability relates.

         (ii) If the indemnification provided for in clause (i) above for any
     reason is held by a court of competent jurisdiction to be unavailable to an
     indemnified party in

                                       23
<PAGE>
 
     respect of any losses, claims, damages, judgments, expenses or liabilities
     referred to therein, then each indemnifying party under such paragraph, in
     lieu of indemnifying such indemnified party thereunder, shall contribute to
     the amount paid or payable by such indemnified party as a result of such
     losses, claims, damages, judgments, expenses or liabilities in such
     proportion as is appropriate to reflect the relative fault, if any, of the
     Company and the other selling Holders in connection with the statements or
     omissions which resulted in such losses, claims, damages, expenses or
     liabilities, as well as any other relevant equitable considerations. The
     relative fault of the Company and the selling Holders shall be determined
     by reference to, among other things, whether the untrue statement or
     alleged untrue statement of a material fact or the omission or alleged
     omission to state a material fact relates to information supplied by the
     Company or the selling Holders and the parties' relative intent, knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. The Company, the Holders, and the underwriters agree that it
     would not be just and equitable if contribution pursuant to this clause
     (ii) were determined by pro rata or per capita allocation or by any other
     method of allocation which does not take account of the equitable
     considerations referred to in the immediately preceding sentence. The
     obligations of any Holder under this clause (ii) are several, not joint,
     and shall be limited to an amount equal to the net proceeds to such Holder
     of Registrable Securities sold pursuant to the Registration Statement to
     which the loss, claim, damage, judgment expense or liability relates. No
     person found guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation.

         (iii)  If any action or proceeding (including any governmental or
     regulatory investigation or proceeding) shall be brought or asserted
     against any indemnified party with respect to which indemnity may be sought
     against the indemnifying party pursuant to this Section 12(f), such
     indemnified party shall promptly notify the indemnified party in writing
     and the indemnifying party shall have the right to assume the defense
     thereof, including the employment of counsel reasonably satisfactory to
     such indemnified party and the indemnifying party shall be responsible for
     the payment of all fees and expenses; provided, however, that the omission
     so to notify the indemnifying party shall not relieve the indemnifying
     party from any liability that it may have to any indemnified party (except
     to the extent that the indemnifying party is materially prejudiced or
     otherwise forfeits substantive rights or defenses by reason of such
     failure).  An indemnified party shall have the right to employ separate
     counsel in any such action or proceeding and to participate in the defense
     thereof, but the fees and expenses of such counsel shall be at the expense
     of such indemnified party unless (1) the indemnifying party agrees in
     writing to pay such fees and expenses, (2) the indemnifying party has
     failed promptly to assume the defense and employ counsel satisfactory to
     the indemnified party or (3) the named parties to any such action or
     proceeding (including any impleaded parties) include both the indemnified
     party and the indemnifying party and such indemnified party shall have been
     advised in writing by its counsel that representation of it and the
     indemnifying party by the same counsel would be inappropriate under
     applicable standards of professional conduct (whether or not such
     representation has been proposed) due to actual or potential differing
     interests between them (in which case the indemnifying party shall not have
     the right to assume the defense of such action on behalf of such
     indemnified party). It is 

                                       24
<PAGE>
 
     understood that the indemnifying party shall not, in connection with any
     one such action or separate but substantially similar or related actions in
     the same jurisdiction arising out of the same general allegations or
     circumstances, be liable for the fees and expenses of more than one
     separate firm of attorneys (in addition to any local counsel) at any time
     for such indemnified parties which firm shall be designated in writing by
     the Holders of a majority in interest of the Registrable Securities on
     behalf of the Holders of all of the Registrable Securities, and that all
     such fees and expenses shall be reimbursed as they are incurred. The
     indemnifying party shall not be liable for any settlement of any such
     action effected without the written consent of the indemnifying party
     (which shall not be unreasonably withheld), but if settled with the written
     consent of the indemnifying party, or if there is a final judgment with
     respect thereto, the indemnifying party agrees to indemnify and hold
     harmless each indemnified party from and against any loss or liability by
     reason of such settlement or judgment. The indemnifying party shall not,
     without the prior written consent of each indemnified party affected
     thereby, effect any settlement of any pending or threatened proceeding in
     which such indemnified party has sought indemnity hereunder, unless such
     settlement includes an unconditional release of such indemnified party from
     all liability arising out of such action, claim, litigation or proceeding.

     (g)  Survival.
          -------- 

          The provisions of this Section 12 shall survive the termination or
     expiration of this Warrant Agreement.

     Section 13.  Fair Market Value.  In order to determine Fair Market Value
                  -----------------                                            
for purposes of this Warrant Agreement, the Company and a representative (the
"Representative") designated by the Holders shall attempt to agree upon such
Fair Market Value. If the Company and the Representative are unable to agree
upon the Fair Market Value within 20 days after notification of the event
requiring such a determination, the Company and the Representative shall agree
on an Appraiser to be appointed by the Company to determine the Fair Market
Value. In the event that the parties cannot agree upon an Appraiser in the
foregoing period, then the determination of Fair Market Value shall be conducted
by two Appraisers, one of whom shall be selected by the Company, and one of whom
shall be selected by the Representative. If either of such two determinations of
Fair Market Value is within ten percent (10%) of the other determination of Fair
Market Value, then the Fair Market Value shall be the average of such two
determinations. The Company shall pay the expenses of each such Appraiser. If
neither of such two determinations of Fair Market Value is within ten percent
(10%) of the other determination of Fair Market Value, a third Appraiser shall
be selected by the other two Appraisers. The third Appraiser shall make its own
independent final determination of Fair Market Value.  The Company shall pay the
expenses of such third Appraiser. All appraisal reports shall be in writing,
shall be signed by the Appraisers and shall be delivered to the Company and the
Holders. The Fair Market Value determined pursuant to this Section 13 shall be
final and binding upon the Company and the Holders.

     Section 14.  Adjustment of Exercise Price and Number of Shares of Common
                  -----------------------------------------------------------
Stock Purchasable or Number of Warrants.  In addition to any reduction in the
- ---------------------------------------                                        
Exercise Price required pursuant to Section 2(b)(vii) above, prior to the
Expiration Date, the Exercise Price, the number 

                                       25
<PAGE>
 
of shares of Common Stock purchasable upon the exercise of each Warrant and the
number of Warrants outstanding are subject to adjustment from time to time upon
the occurrence of any of the events enumerated in this Section 14.

     (a) In case the Company shall at any time after the date of this Warrant
Agreement (i) make a distribution to holders of shares of Common Stock of
additional shares of Common Stock or of Other Securities, (ii) subdivide the
outstanding shares of Common Stock, (iii) combine the outstanding shares of
Common Stock into a smaller number of shares of Common Stock, or (iv) issue any
Other Securities by reclassification of the shares of Common Stock (including
any such reclassification in connection with a consolidation or merger in which
the Company is the continuing entity), then (1) the number and kind of shares of
Common Stock and/or Other Securities issuable, at the time of the record date
for such dividend or of the effective date of such subdivision, combination or
reclassification shall be proportionately adjusted so that the Holder(s) after
such time shall be entitled to receive upon exercise of its Warrants the
aggregate number and kind of shares of Common Stock and/or Other Securities
which, if its Warrants had been exercised immediately prior to such time, it
would have owned upon such exercise and been entitled to receive by virtue of
such dividend, subdivision, combination or reclassification and (2) the Exercise
Price shall be proportionately adjusted.  Such adjustment shall be made
successively whenever any event listed above shall occur.

     (b)  (i)  In case the Company shall issue any Common Stock or any class or
     series of capital stock that is not Preferred Stock at a price per share
     less than the greater of (i) $___ and (ii) the Fair Market Value per share
     of such security (such greater amount being hereinafter referred to as the
     "Base Rate"), then the Exercise Price in effect at the opening of business
     on the day next following such issuance shall be adjusted to equal the
     price determined by multiplying (A) the Exercise Price in effect
     immediately prior to the opening of business on the day next following such
     issuance by (B) a fraction, the numerator of which shall be the sum of (x)
     the number of shares of all classes and series of capital stock (other than
     Preferred Stock) outstanding on the close of business on the day next
     preceding the day of such issuance and (y) the number of shares that could
     be purchased at the Base Rate from the aggregate proceeds to the Company
     from the issuance of such new shares of capital stock, and the denominator
     of which shall be the sum of (xx) the number of shares of all classes and
     series of capital stock (other than Preferred Stock) outstanding on the
     close of business on the day next preceding the day of such issuance and
     (yy) the number of additional shares of capital stock being issued.  For
     purposes of this Section, "Fair Market Value" shall mean, as to any class
     or series of capital stock that is not publicly traded, the fair value of
     the shares of such class or series as determined in accordance with Section
     13 hereof and, as to publicly-traded securities, shall mean the average of
     the daily Current Market Prices of a share of such capital stock during the
     ten (10) Trading Days immediately preceding the effective day of the
     Exercise Price adjustment pursuant to this subsection.  Upon each
     adjustment of the Exercise Price, the number of Warrant Shares that a
     Holder of a Warrant shall be entitled to receive upon exercise shall be
     adjusted by multiplying the number of Warrant Shares

                                       26
<PAGE>
 
     issuable upon exercise immediately prior to such adjustment by a fraction,
     the numerator of which is $______________ and the denominator of which is
     the Exercise Price after such adjustment.

          (ii) If at any time Company shall issue or sell any Options or any
     Convertible Securities, whether or not the rights to exercise, exchange or
     convert thereunder are immediately exercisable, and the price per share for
     which Common Stock is issuable upon the exercise of such Options or upon
     conversion or exchange of such Convertible Securities shall be less than
     the Base Rate in effect immediately prior to the time of such issue or
     sale, then the number of shares for which a Warrant is exercisable and the
     Exercise Price shall be adjusted as provided in Section 12(b)(i) above on
     the basis that the maximum number of additional shares of Common Stock
     issuable pursuant to all such Options or necessary to effect the conversion
     or exchange of all such Convertible Securities shall be deemed to have been
     issued and outstanding and Company shall be deemed to have received all of
     the consideration payable therefor, if any, as of the date of the issuance
     of such Options and Convertible Securities.  No further adjustments of the
     Exercise Price shall be made upon the actual issue of such Common Stock or
     of such Convertible Securities upon exercise of such Options or upon the
     actual issue of such Common Stock upon such conversion or exchange of such
     Convertible Securities or upon the expiration or termination of such
     Options or Convertible Securities.  If the number of shares for which any
     Option is exercisable or the rate at which any Convertible Securities are
     convertible into or exchangeable for shares of Common Stock shall increase,
     the number of shares of Common Stock purchasable upon the exercise of the
     Warrants in effect at the time of such event shall promptly be readjusted
     to the number of shares of Common Stock which would have been so
     purchasable at such time had such Options or Convertible Securities
     initially been exercisable or convertible into such changed number of
     shares of Common Stock and the Exercise Price shall be adjusted
     accordingly.  The provisions of this Section 14(b)(ii) shall not apply to
     the issuance by the Company of GMAC Warrants to purchase 1,624,650 shares
     of Common Stock.  The provisions of this Section 14(b) also shall not apply
     to any issuance of shares of Common Stock upon exercise of any Warrants or
     issuances covered by subsections (a), (c) or (f) of this Section 14.

     (c) In case the Company shall fix a record date for making a distribution
to any holders of the shares of Common Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing corporation) of shares of stock other than Common Stock, other
securities, evidences of its indebtedness or assets or property of whatever
nature (excluding cash dividends consistent with past practice), (i) the number
of shares of Common Stock for which a Warrant is exercisable shall be adjusted
to equal the product of the number of shares of Common Stock for which a Warrant
is exercisable immediately prior to such adjustment multiplied by a fraction (A)
the numerator of which shall be the Fair Market Value per share of Common Stock
immediately prior to such record date and (B) the denominator of which shall be
such Fair Market Value per share of Common Stock minus the amount allocable to
one share of Common Stock of any such cash so distributable and of the Fair
Market Value of any and all such shares of stock, other securities, evidences of
indebtedness, or assets or property so distributable, and (ii) the Exercise
Price to be in effect after such record date shall be determined by multiplying
the Exercise Price in effect immediately prior to such record date by a

                                       27
<PAGE>
 
fraction, of which the numerator shall be the current Fair Market Value per
share of Common Stock immediately prior to such record date minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the Fair Market Value of any and all such shares of stock, other securities,
evidences of indebtedness, or assets or property so distributable, and of which
the denominator shall be such current Fair Market Value per share of Common
Stock immediately prior to such record date. Such adjustment shall be made
successively whenever such a record date is fixed; and, if such distribution is
not so made, the Exercise Price shall again be adjusted to be the Exercise Price
which would then be in effect if such record date had not been fixed.

     (d) No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in such price;
provided that any adjustments which by reason of this subsection (d) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Section 14 shall be made to
the nearest hundredth of a cent or to the nearest share of Common Stock, as the
case may be.

     (e) If at any time, as a result of an adjustment made pursuant to
subsection (a) of this Section 14, a Holder shall become entitled to receive any
Other Securities, thereafter the number of such Other Securities so receivable
shall be subject to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions contained in this Section 14.

     (f) In the case of any capital reorganization of the Company, or of any
reclassification of the shares of Common Stock, or in case of the consolidation
of the Company with or the merger of the Company with or into any other
corporation (where the Company is not the Surviving Corporation) or of the sale
of the properties and assets of the Company as, or substantially as, an entirety
to any other company, each Warrant shall after such capital reorganization,
reclassification of shares of Common Stock, consolidation, merger or sale be
exercisable, upon the terms and conditions specified in this Warrant Agreement,
for the number of shares of stock and the cash or other securities or property
of any nature whatsoever that is receivable upon or as a result of the
reorganization, reclassification, consolidation, merger or sale by a holder of
the number of shares of Common Stock (or Other Securities) for which a Warrant
is exercisable immediately prior to such event; and in any such case, if
necessary, the provisions set forth in this Section 14 with respect to the
rights thereafter of the Holders shall be appropriately adjusted so as to be
applicable, as nearly as may reasonably be, to any shares of stock or other
securities or assets thereafter deliverable on the exercise of the Warrants. The
subdivision or combination of the shares of Common Stock at any time outstanding
into a greater or lesser number of units or any other event covered by
subsection (a) of this Section 14 shall not be deemed to be a reclassification
of the shares of Common Stock for the purposes of this subsection (f). The
Company shall not effect any such consolidation, merger or sale, unless prior to
or simultaneously with the consummation thereof, the successor corporation
resulting from such consolidation or merger or the corporation purchasing such
assets or the appropriate corporation or entity shall assume, by written
instrument, the obligation to deliver to each Holder the shares of stock, cash,
other securities or assets to which, in accordance with the foregoing
provisions, each Holder may be entitled to and all other obligations of the
Company under this Warrant Agreement.

                                       28
<PAGE>
 
     (g) In case of any adjustment or readjustment in the Warrants, Warrant
Shares  or Exercise Price in accordance with this Section 14, the Company at its
expense will promptly compute such adjustment or readjustment in accordance with
the terms of this Warrant Agreement and cause independent public accountants of
recognized national standing selected by the Company to verify such computation;
and the Company will prepare a report, certified by the principal financial
officer of the Company, setting forth such adjustment or readjustment and
showing, in detail, the facts upon which such adjustment or readjustment is
based, and all calculations relating to any adjustments made in accordance with
this Section 14. The Company will forthwith mail a copy of each such report to
each Holder, and will, upon the written request at any time of any Holder,
furnish to such Holder a report setting forth such information as may be
requested by such Holder, including any calculations with respect thereto in
order that such Holder may verify such calculations.

     Section 15. Fractional Warrants and Fractional Warrant Shares.
                 -------------------------------------------------
The Company shall not be required to issue a fractional share
of Common Stock upon exercise of any Warrant. As to any
fraction of a share which the Holder of one or more Warrants,
the rights under which are exercised in the same transaction,
would otherwise be entitled to purchase upon such exercise, the
Company shall pay a cash adjustment in respect of such final
fraction in an amount equal to the same fraction of the Current
Market Price per share of Common Stock on the date of exercise.


     Section 16.  Financial Information.
                  ---------------------   

     (a) The Company will furnish to the Holders the reports and information
that is required to be delivered to the Company's stockholders.

     (b) Unless otherwise specified herein, all accounting terms used herein
shall be interpreted, all accounting determinations hereunder shall be made, and
all financial statements required to be delivered hereunder shall be prepared in
accordance with GAAP, applied on a basis consistent (except for changes
concurred in by the Company's independent public accountants) with the most
recent audited consolidated financial statements of the Company.

     Section 17.  No Rights or Liabilities as Shareholder.  Nothing contained in
                  ---------------------------------------  
this Warrant Agreement shall be construed as conferring upon the Holder any
rights as a shareholder of the Company or as imposing any liabilities on the
Holder as a shareholder of the Company, whether such liabilities are asserted by
the Company or by creditors or shareholders of the Company or otherwise.

     Section 18.  Decisions of Holders. All decisions to be made and actions to
                  --------------------  
be taken by the Holders as a group pursuant to this Warrant Agreement will be
made or taken by a majority in interest of the Holders (each Warrant counting as
the number of Warrant Shares obtainable upon the exercise of the Warrant at such
time).

     Section 19.  Notices to Holders. In case:
                  ------------------

similar subscription rights; or

     (b) the Company shall authorize a dividend or the distribution to all
holders of shares of Common Stock of evidences of its indebtedness or assets
(including distributions payable in shares of Common Stock and cash dividends or
distributions, other than cash dividends consistent with past practice); or

     (c) of any consolidation or merger to which the Company is a party and for
which approval of any shareholders of the Company is required, or of the
conveyance or transfer of all or substantially all of the properties and assets
of the Company, or of a capital reorganization or reclassification or change of
the shares of Common Stock; or

     (d) of the voluntary or involuntary dissolution, liquidation or winding up

     (e) the Company proposes to take any other action which would require an
adjustment of the number of Warrant Shares issuable upon exercise of the
Warrants or an adjustment of the Exercise Price pursuant to Section 14;

then the Company shall cause notice to be given to each Holder of shares of
Common Stock at its address appearing on the Register, at least 30 calendar days
prior to the applicable record or effective date specified.  Such notice shall
state (i) the date as of which the holders of record of shares of Common Stock
to be entitled to receive any such dividend, rights, warrants or distribution

conveyance, transfer, dissolution, liquidation, winding up or other action is
expected to become effective, and, if applicable, the date as of which it is

     Section 20.  Amendments and Waivers. Any provision of this Warrant 
                  ----------------------     
Agreement or the Warrant Certificates may be amended or waived if, but only if,
such amendment or waiver is in writing and is signed by the Company and two
thirds of the Holders; provided that the Warrant Agreement and the Warrant
                       --------
Certificate may not be modified or amended to reduce the number of shares of
Common Stock for which a Warrant is exercisable or to increase the price at
which such shares may be purchased upon exercise of a Warrant without the prior
written consent of the Holder thereof. Notwithstanding the foregoing, a waiver
or consent to departure from the provisions hereof that relates exclusively to
the rights of Holders of Registrable Securities whose securities are being sold
pursuant to a Registration Statement and that does not directly or indirectly
affect the rights of other Holders of Registrable Securities shall be valid only
with the written consent of Holders of at least 66-2/3% of the Registrable
Securities being sold.

                  --------                                                  
survive the exercise of any Warrant in whole or part and, in event of such
exercise, the term "Holder" shall refer to the holder of any Warrant Shares
issued upon exercise hereunder; provided, however, that in the case of any sale
of Subject Securities pursuant to a Public Offering or Rule 144 under 

                                       30
<PAGE>
 
the Act, the Subject Securities which are so transferred will no longer have the
benefits of this Warrant Agreement.

     Section 22.  Indemnification.  Company agrees to indemnify and hold 
                  ---------------     
harmless the Holders from and against any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs, attorneys' fees,
expenses and disbursements of any kind which may be imposed upon, incurred by or
asserted against the Holders in any manner relating to or arising out of any
litigation to which a Holder is made a party in its capacity as a stockholder or
warrantholder of Company; provided, however, that the Company will not be liable
                          --------  -------                                     
hereunder to the extent that any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, attorneys' fees, expenses
or disbursements are found in a final non-appealable judgment by a court to have
resulted from a Holder's fraud or willful misconduct in its capacity as a
stockholder or warrantholder of the Company.

     Section 23.  Expenses. Except as provided herein, the Company shall pay all
                  --------                                                    
reasonable legal and other professional fees (and related disbursements) of
First Union in connection with this Warrant Agreement and the transactions
contemplated hereby.

     Section 24.  Notices.  Any notice or demand authorized by this Warrant
                  -------                                                    
Agreement to be given shall be in writing and shall be delivered in person, sent
by telecopy, mailed (registered or certified, return receipt requested), postage
prepaid, or sent by overnight delivery service addressed to the Company or the
Holders at their respective addresses specified above or in the Register or, as
to any such party, at such other address as may be designated by it in a notice
to the other parties hereto. All notices shall be deemed to be properly given or
made upon the earlier to occur of (i) actual delivery, (ii) 5 days after being

service. For the purposes of notices sent by facsimile, the parties' facsimile

     Section 25.  Binding Effect.  This Warrant Agreement shall be binding upon
                  --------------
and inure to the sole and exclusive benefit of the Company, and its permitted
successors and each registered Holder from time to time of the Subject
Securities and each of its respective permitted successors.

     Section 26.  Termination.  Except as provided herein, this Warrant 
                  -----------
Agreement shall terminate and be of no further force and effect at the close of
business on the Expiration Date unless, prior to such Expiration Date, there
shall no longer be any Holders in which event this Warrant Agreement shall
terminate as of such date except with respect to the provisions hereof which are
intended to survive.

     Section 27.  Severability.  In the event that any provision of this Warrant
                  ------------    
Agreement is held to be invalid, prohibited or unenforceable in any jurisdiction
for any reason, unless such provision is narrowed by judicial construction, this
Warrant Agreement shall, as to such jurisdiction, be construed as if such
invalid, prohibited or unenforceable provision had been more narrowly drawn so
as not to be invalid, prohibited or unenforceable. Notwithstanding the
foregoing, if any provision of this Warrant Agreement is held to be invalid,
prohibited or unenforceable in any jurisdiction, such provision, as to such
jurisdiction, shall be ineffective to 

                                       31
<PAGE>
 
the extent of such invalidity, prohibition or unenforceability without
invalidating the remaining portion of such provision or the other provisions of
this Warrant Agreement and without affecting the validity or enforceability of
such provision or the other provisions of this Warrant Agreement in any other
jurisdiction.

     Section 28.  Counterparts. This Warrant Agreement may be executed by one or
                  ------------
more of the parties hereto on any number of
separate counterparts and all of said counterparts taken together shall be
deemed to constitute one and the same instrument.

     Section 29.  Governing Law; Remedies.
                  -----------------------   

     (a) This Warrant Agreement and each Warrant Certificate shall be construed
in accordance with and governed by the laws of the State of New York (without
giving effect to its conflicts of law principles).

     (b) Each holder of a Subject Security, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant Agreement.
The Company agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this Warrant
Agreement and hereby agrees to waive the defense in any action for specific
performance that a remedy at law would be adequate.

     Section 30.  No Impairment. If any event occurs as to which the provisions
                  ------------- 
of this Warrant Agreement or the Subject Securities are strictly applicable and
the application thereof would not fairly protect the rights of the Holders in
accordance with the essential intent and principles of such provisions, then the
Company shall make such adjustments in the application of such provisions, in
accordance with such essential intent and principles, as shall be reasonably
necessary to protect such rights as aforesaid.

NOVASTAR FINANCIAL, INC. ANNOUNCES
- -----------------------------------

                     EXPANDED RELATIONSHIP WITH FIRST UNION
                     --------------------------------------

(WESTWOOD, KANSAS - February 16, 1999) - NovaStar Financial, Inc. (NYSE: NFI)
announced today that it has entered into certain agreements that significantly
expand its relationship with its primary lender, First Union National Bank and
its affiliates (collectively, "First Union").

As a result of the new arrangement, First Union will be providing a
significantly increased level of financing to the Company and its affiliates
through the following facilities: $75 million revolving warehouse line of
credit, $300 million whole loan repurchase facility, and $20 million of residual
financing.  All of the facilities are committed for one year, maturing February
2000.  In connection with the new arrangements, the Company will issue to First
Union 350,000 warrants to purchase NovaStar common stock at $6.9375 per share,
the closing price on February 11, 1999, in exchange for 186,667 existing
warrants to purchase NovaStar common stock at a price of $15 per share, which
will be retired.

"First Union has been tremendously supportive during the turbulent events of the
last five months.  They have served as our primary warehouse lender from
inception and we are extremely pleased to announce that we have taken a major
step in solidifying our long-term liquidity position by expanding our
relationship with them," said Scott Hartman, Chairman and CEO.  "We continue to
pursue additional arrangements that would supplement the facilities provided by
First Union and bring additional liquidity and capital to NovaStar."

Hartman commented further, "We expect to use proceeds from the First Union
residual facility to repay borrowings under the GMAC/RFC facility on or before
its maturity date of February 28, 1999.  GMAC/RFC provided us with much needed
liquidity during a very difficult time and we appreciate their support.  We
continue to negotiate with GMAC/RFC to develop a long-term lending relationship.
However, we do not envision that such a relationship would involve the issuance
of 811,919 additional warrants at $4.5625 per share, as previously contemplated.
Such a long-term lending arrangement with GMAC/RFC could include some level of
additional warrants at current market prices."

The Company had previously announced it had entered into a short-term secured
financing agreement with GMAC/RFC for $15 million to address liquidity needs.
That facility was initially scheduled to mature on January 13, 1999, and was
extended to February 28, 1999, as the Company and GMAC/RFC continued
negotiations towards a long-term strategic alliance.  In 

                                       1

connection with that financing arrangement, the Company agreed to issue GMAC/RFC
warrants for the purchase of 812,731 shares of common stock at an exercise price
of $4.5625, the closing price on October 12, 1998.

NovaStar Financial, Inc. is a real estate investment trust (REIT) that invests
in the single-family residential subprime mortgage loans originated by its
affiliate, NovaStar Mortgage, Inc.  Mortgage loans in portfolio are financed on
a long-term basis by issuing collateralized mortgage obligations accounted for
as debt instruments.  NovaStar Financial, Inc. is located in Westwood, Kansas, a
part of the Kansas City metropolitan area.  NovaStar Mortgage's operates its
wholesale lending operation in Orange County, California, and its servicing
operation in Westwood, Kansas.

Certain matters discussed in this news release may constitute forward-looking
statements within the meaning of the federal securities laws that inherently
include certain risks and uncertainties.  Actual results and the timing of
certain events could differ materially from those projected in or contemplated
by the forward-looking statements due to a number of factors, including general
economic conditions, fluctuations in interest rates, the availability of
subprime residential mortgage loans, the availability and access to financing
and liquidity resources, and other risk factors outlined in the Company's 1997
annual report on Form 10-K.
